    System and method for recharging nomadic electronic devices, and adapter for such a system
    FIELD OF THE INVENTION
    The present invention relates to systems for recharging nomadic electrical or electronic devices. It relates in particular to a charging system and method that are suitable for a wide variety of devices provided with autonomous power supply means, especially telephone notebooks. The invention also relates to an adapter for equipping such devices and facilitate recharging.
    BACKGROUND OF THE INVENTION
    Current electric charging solutions are not always effective and often have disadvantages. As for the conventional chargers generally supplied with the device to be recharged, the charging process is certainly fast and efficient. However, it is not systematic to carry this type of charger on oneself. Also, their use is mainly confined to the private home.
    Several other technologies meet the need to charge mobile devices, but in the absence of a dedicated charger, we do not find in practice a simple system (and intuitive) of use and compatible with a wide variety of devices.
    One can mention the category of portable batteries that can be connected to an electrical device to recharge usually out of the home. These batteries have the advantage of providing a charging device available everywhere but also the disadvantage of adding constraints for the user: in addition to having to charge his phone (or other nomadic device), it will also think to load his portable battery device, and to constantly prevail with him.
    There are also public charging stations, usually raw electrical outlets, raw USB plugs or apparent charging cables available in transit locations such as airports, train stations, libraries, fast food outlets. The purpose of these installations is to provide energy to the users present in these places. These public charging stations have the disadvantage of being able to recharge only one device per terminal, thus limiting the total number of devices that can be recharged.
    Inductive charging makes it possible to charge mobile devices in an intuitive way, the user only needs to put his device on a charging base to recharge it, without going through a wired connection. However, induction charging has the disadvantage of being able to recharge only one device per coil, making it an expensive device and difficult to use to recharge a large number of devices in a defined space. In addition, the effectiveness of these refills is not optimal because of the losses caused by induction. Also note that the practical side of this technology is strongly impacted by the fact that the user is forced to put his phone at the exact location where the coil or inductions. It is therefore often necessary in practice to add a mechanical retention mechanism that guides the device in position. This limits the variety of devices that can be recharged this way.
    Document US Pat. No. 739,2068 B2 (also published under the reference WO 03075415 A1) discloses an electricity distribution system that allows conductive electrical charging while allowing a degree of freedom of movement of the apparatus. For this, the system has a substantially flat recharge surface which has a plurality of contact areas for adapting to a multitude of positions of the receiving input terminals placed in a bottom face of the apparatus.
    The input terminals are part of a device-specific adapter that must be configured to communicate identification information to a control unit of the electricity distribution system. It should be noted that this type of adapter is very specific and can not cooperate with a wide variety of electrical or electronic devices. In addition, the authentication process of the adapter is complex and makes this type of solution unsuitable in places of passage. To recharge several devices of different range, it must also be possible to change the parameters of the current delivered by each of the contact areas, which adds an additional cost to the system.
    OBJECTS OF THE INVENTION
    The present invention aims to overcome one or more of the aforementioned drawbacks by proposing a highly compatible electricity distribution system for recharging, successively or simultaneously, a very wide variety of nomadic electrical or electronic devices, for example telephones. latest-generation mobile devices, GPS positioning devices, other similar communication devices, audio / video recording or sound and / or visual reproduction, and which requires a minimum of effort on the part of the user to obtain a efficient charging, by direct conduction. For this purpose, the invention relates to a power distribution system for recharging and / or powering, successively or simultaneously, nomadic electrical or electronic devices provided with autonomous power supply means, the system comprising: carrier having a substantially planar charging surface defined essentially by: a plurality of conductive contact areas distributed in two directions forming adjacent rows, and isolation gaps between the contact areas, a control module for selectively supplying the contact areas with current (so that the contact areas are either in a functional state or in an inactive state); and at least one adapter with two electrically conductive input terminals forming two surface portions spaced apart by a predetermined distance and adapted to cooperate by direct conduction contact with two contact areas of the charging surface; the adapter comprising a strip which incorporates the two input terminals and which has: a substantially flat outer surface comprising or defining an electrically insulating coating, the two surface portions forming part of the outer face, the outer face being dimensioned and configured so that the predetermined distance is at least three times greater than the largest extent of any of the two surface portions; an inner face opposite to the outer face and adapted to be fastened against a face of a nomadic electrical or electronic device; and a bent portion offset from the inner face and electrically connected to both surface portions.
    Thanks to these provisions, it is permitted to simply put on the charging surface a main face (it is for example a backside opposite to a display screen when the device is a mobile phone or a tablet) of a device previously equipped with the adapter. Compared to induction charging, the system is more efficient (electrical conduction) and the small size of the two input terminals of the adapter relative to their spacing allows several positioning on typically wide contact areas (unlike the induction charging, where the device must be placed above the location of the coils).
    The useful section of the input terminals may be advantageously of the same order of magnitude as the isolation spacings between two adjacent contact areas (but being typically smaller) and the predetermined distance significantly exceeds the maximum extension of a zone. contact, so as to avoid inadvertently shorting.
    The strip can be compatible with any device, with only the need, if any, for the adapter to include a specific, low-profile connector member on the side of the bent portion. In practice, the headband can simply be extended by a universal connector member having a micro USB or USB plug (Universal Serial Bus). The son or connection elements of such a plug ("VBUS" and "GND") are connected to the electrically conductive wires or bands, internal to the strip, which extend to the two input terminals.
    It should be noted here that the "USB-C" type charging port can obviously form the port in which the connector member of the adapter can be inserted. The USB-C port has been developed and officially adopted by the USB-IF group ("USB Implementers Forum") which has more than 700 companies (including Apple, Dell, HP, Intel,
    Microsoft and Samsung), which suggests a wide adoption by the electronics market. More generally, it can be considered that the strip has a universal character and it is sufficient to properly associate the micro-connector (whose size is typically at least ten times lower than a conventional charger) that fits in the port of the device to recharge.
    According to one feature, the inner face is at least partly adhesive and forms a flat attachment surface, so that the strip forms a sticker that extends in a longitudinal direction between the bent portion and a distal end. Thus, we can keep the adapter with the device (the embedded adapter having an additional negligible space), and if necessary take off the sticker when you want to use the device without the adapter.
    According to a particular feature, the headband of the adapter is removably attached to a connector member. This allows to leave the banner (for example in the form of a sticker) attached to the device, while releasing the charging port of the device. More generally, it is understood that the adapter can be adapted to allow charging of the device by a conventional charger without the need to detach the adapter completely or move the headband of the adapter.
    According to one feature, the bent portion of the strip has attachment means for releasably securing the strip to the connector member, selectively in a first configuration or a second configuration distinct from the first configuration, so that the relative position of the headband relative to the connector member may be modified without moving the connector member in a state connected to a device to recharge.
    According to one feature, the contact between the connector member and the strip (typically the bent part of the strip) can be done by magnetization, preferably with the possibility of detaching the strip by exerting a force greater than the magnetic attraction force. Small magnets can thus be placed in a housing constituting the connector member. They attract a ferromagnetic portion of the bent portion, thereby creating a contact between the two parts of the adapter and a passage of the current. This type of removable attachment is advantageous in that it makes it possible to modify the relative position of the connector member relative to the bent part (bend in one direction or the other, depending on the face that is desired cover by the banner, knowing that the micro USB charging sockets for example are not always oriented in the same direction on the devices).
    According to one feature, the system comprises a group of several adapters each provided with a corresponding strip (strip identical or essentially different in size), so that the system is adapted to simultaneously recharge several electrical appliances or electronic nomads equipped with a respective adapter of said group. It will be understood that the recharging surface, which may have a plurality of rows of contact zones, allows itself to recharge simultaneously at least two devices (for example a mobile phone and a music player), each equipped with an adapter of the adapter group.
    In various embodiments of the electricity distribution system according to the invention, one or more of the following arrangements may also be used: the adapter comprises a connector member provided with an insertable portion of removable connection forming a first end of the connector member and a head (eg in the form of a housing) which forms a second end of the connector member opposite the insertable portion; the head of the connector member has a rear end face of electrical connection with the strip and a side face forming a support for fixing (for example adhesive) of the bent portion; - The bent portion comprises a connecting surface for electrically connecting the head of the connector member to the strip; - The strip is elongate and has a length at least twice greater than its largest width (with for example a maximum width of between 9 and 45 mm, preferably between 10 and 35 mm); the strip has at least two parallel fold lines, extending perpendicularly to a longitudinal elongation direction of the strip and allowing to move longitudinally and radially the connection surface relative to the planar attachment surface; the bend portion of the band includes a fold line for defining a band end which deviates from the remainder of the band and extends, in a refill configuration, in an orientation opposite to the refill surface (this end extending from the fold line to a pair of output terminals); the output terminals are part of a substantially planar connecting surface which defines with the internal fastening face a predetermined angle less than 120 °, preferably of the order of 90 °; the adapter comprises a determined connector directly connected to the output terminals, preferably permanently, the determined connector being complementary to a connection port, in particular of the micro USB or USB type, to allow the charging of a device electrical or electronic nomadic (the connector member may, if necessary, correspond to the targeted technology, so it may correspond to the "Lightning®" technology of the Apple® brand to cooperate with devices of this brand); - The bent part of the headband partially covers the head, preferably on the side of the second end; - The contact areas of a given row selected from said rows each have the same perimeter; the perimeter of the contact zones, at least in the determined row, is greater than a length of an assembly formed by three successive contact zones which belong to the determined row; - The predetermined distance has a length exceeding one quarter of said perimeter and preferably is large enough so that the two input terminals can not be located on the same contact area of the charging surface; the predetermined distance is less than half of said perimeter and may optionally be greater than 40 mm, preferably greater than or equal to 55 mm (thus the perimeter may typically be much greater than 80 mm, preferably greater than or equal to 110 mm and optionally each contact area has a regular shape and / or dimensionless narrower than another, when there is a visual distinction between the insulating areas and the contact areas of the charging surface, the large size of a zone contact with the banner allows the user to more easily identify which contact areas are actually used for charging and which contact areas remain available for another device to be recharged); in several of the rows, the contact zones have the same substantially square or hexagonal format, with the same side, so as to define each one of the same surface; the two conductive surface portions, which are preferably of the same external shape and of the same dimensions, are each smaller and of an order of magnitude than the surface defined by the contact zones (in different order of magnitude, it is Of course, a variation of a ratio of about 10 or more must be understood: for example, the surface portion may be only 0.5 cm 2 while the contact zone on which it bears may be greater than 5 cm 2); the format of the contact zones is square in at least one of the rows and the predetermined distance separating the two input terminals preferably satisfies the following relation with respect to the side of the contact zones:
    where a represents the side of a contact zone, and c represents the predetermined distance; the contact zones are staggered and / or comprise at least two distinct types of format; the predetermined distance is at least four or five times greater than the largest extension of any of the two surface portions; the external characteristic dimension of the contact zones is at least five times greater than the separation distance between two adjacent contact zones, preferably at least nine times greater than this separation distance; the external characteristic dimension is for example at least 40 mm and the recharging surface is sized to define at least four parallel rows (non-limiting example) each having at least two contact zones in an active use state, whereby the charging surface can cooperate simultaneously with a number of adapters at least four which are separately associated with pairs of contact areas, each of these adapters supporting and transferring the charging current to a device provided with a charging port; the control module comprises detection means for testing a state of use of each of the contact zones.
    It is also proposed an adapter for electrical or electronic nomadic devices, provided with two electrically conductive input terminals forming two surface portions spaced apart by a predetermined distance and adapted to cooperate by direct conduction contact with a charging surface, which defines said adapter of the electricity distribution system according to the invention, comprising a strip which includes the two input terminals and which has: a substantially flat outer surface comprising or defining an electrically insulating coating, the two surface portions forming part of the outer face, the outer face being dimensioned and configured so that the predetermined distance is at least three times greater than the largest extension of any of the two surface portions; an internal face opposite to the outer face and adapted to be fastened against a face of a nomadic electrical or electronic device, preferably opposite to a display screen; and a bent portion offset from the inner face and electrically connected to both surface portions.
    Such an adapter facilitates the correct positioning of the device on a large charging surface that can typically be used to charge multiple devices simultaneously. The latest generation of phones ("smartphones") and tablets usually need to connect to computers, and for this the almost unique standard is USB, which corresponds to a voltage of 5V. Thus all devices of this kind are provided with an interface that corresponds to the standard USB input (5.25 V to 4.75 V) and which lowers this voltage to match that of the internal battery (usually 3 or 4 V). All of these devices (regardless of brand) operate in 5V input, so an adapter as defined above may be suitable for charging by direct current conduction of a wide variety of electrical or electronic devices.
    Of course, the adapter may be capable if necessary of operating for a charging voltage different from the aforementioned values. Optionally, a DC / DC voltage converter can be installed in the adapter. Also, for another use, the nominal voltage provided by the charging surface can be adapted (the contact areas can also provide different voltages depending on the device). As an alternative to USB technology, we can mention the "Lightning®" technology used for devices marketed under the Apple® brand.
    Thanks to the bent part, the connection elements output strip head are particularly well oriented to allow connection to the interface of the device. In addition, because of the attachment against the dorsal face closer to the charging port, there are no free son or similar free parts connectivity can be inserted under the device placed on the charging surface and may prevent efficient conduction to the nearest input terminal of the charging port.
    According to one feature, the adapter comprises a rigid head connector member and which has an insertable removable connection portion distinct from said head (typically USB or micro USB type, without being limiting), the bent portion being connected to the head of the connector member and having an adjustment portion in the defined position between a first fold line of the proximal strip relative to the connector member and a second fold line of the strip distal from the connector member. With this type of adjustment, the output connection elements are well oriented, regardless of the small variations in distance that may exist, from one device to another, between the interface on the edge and the face (usually a face dorsal) on which the inner face of the band is contiguous.
    Another object of the invention is to provide an electric charging method which combines efficiency and ease of use with a wide range of devices. For this purpose, it is proposed a power distribution method for recharging, successively or simultaneously, several electrical or electronic nomadic devices provided with autonomous power supply means, by using a substantially flat recharge surface which has a plurality of zones. conductive contacts distributed in two directions forming adjacent rows, the method comprising for each apparatus reloading the steps of essentially: connecting an adapter to a charging port of the apparatus via a removably connectable connector member , preferably on the side of a slice of the apparatus, the adapter comprising a strip which extends the connector member and which is provided on an outer face with two electrically conductive input terminals forming two surface portions; attaching and attaching, in a zone of attachment, an internal face of the strip opposite the outer face against a face of the device, keeping the connector member away from the attachment zone and in a state of electrical connection to part of the band which is bent; placing the adapter between the apparatus and the recharge surface by directly contacting the two surface portions with conduction on separate contact areas of the recharging surface, knowing that the two surface portions are spaced apart from one another; a predetermined distance at least three times greater than the largest extension of any of the two surface portions; and selectively supplying contact areas with current, so that the two contact areas on which the two surface portions rest are in a functional state and allow recharging via the adapter.
    According to a feature, each of the contact zones is supplied with the same voltage of between approximately 4 V and approximately 5.25 V, for example between 4.75 V and 5.25 V, the detachably connected connector member being for example USB or micro-USB type.
    Advantageously, there is no need to specifically orient the device or devices to recharge, once they equipped with the adapter. The method can be implemented in several contexts. It is thus possible to install this system in all places where the user spends time waiting or is motionless for a certain time: transport (airports, stations ..), restaurants, universities, waiting rooms, factories, offices . It is also possible to install this system at home.
    To allow users access to the charging surface, it is possible to market separately a number of adapters (with the possibility for the user to keep the adapter that forms a typically repositionable tab).

    DESCRIPTION OF EMBODIMENTS OF THE INVENTION
    In the various figures, identical references indicate identical or similar elements.
    With reference to FIGS. 1, 2 and 4, the electricity distribution system 1 comprises a stationary part 2 and at least one adapter 3 which is mounted on a nomadic device 4 (electric or electronic) to be recharged. There is no wired connection between the stationary part 2 and the adapter 3 and no male or female part to make the electrical connection of the adapter 3 to the charging surface 5 of the stationary part 2. The adapter 3 simply presents two electrically conductive input terminals B1, B2 (for example metallic) which are located in a substantially flat outer face F2 of a strip B.
    In an assembled configuration of the adapter 3, the strip B matches the plane relief of a dorsal surface 6 of the device 4, so as to expose the external face F2 on the side of a main face (typically a parallel face and opposite to a display screen of the device 4). In variants, the strip B can be attached, in addition or in replacement, to the sidewalls or even the front (at least in part) of a device 4. It is understood that the strip B may, optionally, marry in part a sidewall of a device 4 which is placed on the side of this flank against the charging surface 5.
    Stationary part
    Referring to Figures 2 and 4, the stationary portion 2 comprises a control module M and a support device 8 which has a charging surface 5 substantially flat and adapted to provide charging current. The control module M is configured to selectively power the contact areas 9 distributed over the charging surface 5. These contact areas 9 are electrically conductive and separated from each other by insulation spacings 10. The spacings 10 define a separation distance D10 between two adjacent contact areas 9.
    The contact areas 9 are distributed in two directions forming adjacent rows R1, R2, R3, R4. The support device 8 may be in the form of a plate which comprises an insulating substrate 8a, cut elements 80 which are conductive and define the contact zones 9, and a wire connection 11 allowing each cut element 80 to be connected to the control module M. In the non-limiting example of Figures 2 and 4, the contact areas 9 have a shape corresponding to a square or a general shape of square or rectangle. It is preferable that the separation distance D10 be reduced with respect to the side a here defined by the contact zones 9.
    The support device 8 can be cut into the desired shape. It allows to distribute energy on a given surface which typically breaks down into at least two rows R1, R2, R3, R4 each having at least two, three or four contact zones 9. This arrangement allows, if necessary, recharging of several devices 4, which simultaneously have access to this energy. As can be clearly seen in FIG. 4, the energy can come from a single electrical socket 12 in connection with the control module M.
    Alternatively, a single row may be provided. For an application that does not target a simultaneous charging of devices 4 on the same charging surface 5, it is understood that a minimum of two contact zones 9 is sufficient. By way of nonlimiting example, the insulation used in the support device 8 may be selected from polymers (and derivatives), or wood (and derivatives), or glasses (and derivatives), or other electrical insulating materials. This insulator may be rigid (and preferably non-brittle and impact-resistant) in order to give the support device 8 a certain solidity. When the insulating substrate 8a forms an integral plate, the cut-out elements 80 may be inlaid or embedded in the insulating substrate 8a. The cut elements 80 have for example a thickness of 0.001 mm to 1 mm and form a contact zone 9 whose diagonal (or greater equivalent extension) is typically smaller than the distance c between the two input terminals B1 and B2 of the adapter. More generally, it is understood that the contact zones 9 formed by the cut elements 80 may have a diagonal or equivalent maximum extension sufficiently large to limit the density of the wire connection 11, and for example greater than or equal to 30 or 40 mm.
    In a preferred embodiment, the contact zones 9 of a row R1, R2, R3 or R4 each have the same perimeter which is greater than a length L3 of an assembly formed by three successive contact zones 9 belonging to this row, which shows that the distance D10 is much smaller than the diagonal of a contact zone 9. The predetermined distance c exceeds a quarter of such a perimeter and, preferably, is sufficiently large for the two terminals B1 and B2 inputs can not be located on the same contact area 9 of the charging surface 5.
    Furthermore, it may be advantageous for each contact zone 9 to have a perimeter greater than the predetermined distance and typically such that the predetermined distance c is less than half of said perimeter.
    In practice for generally square or hexagonal contact zones 9 and when the total length of the strip B does not greatly exceed the distance c, this generally avoids that the strip B overlaps more than four contact zones 9 (While it is sufficient that two contact areas are covered by and in contact with the outer face F2 of the strip B to allow charging).
    In the example shown, the cut elements 80 are embedded in the insulating substrate 8a so that the surface "insulator + conductive element" is even and flat (cut elements 80 conductors arranged flush with the insulator). The material of the elements 80 may be selected from metals (and derivatives) or graphite (and derivatives). When the elements 80 form squares or hexagons, they are arranged on the insulating substrate 8a at regular intervals. The distance c between two adjacent contact areas 9 may be chosen according to a DC diameter or equivalent characteristic size of the input terminals B1 and B2 of the adapter 3. Thus, the distance D10 may be greater than the diameter DC.
    The diameter DC must be smaller than the distance D10 if it is desired that a surface portion PSI or PS2 can not connect two different contact zones 9. In practice it may be preferable for the distance D10 to be just smaller than the diameter DC (or equivalent dimension) to prevent the surface portions PSI and PS2 are found in the middle of the insulation too often.
    The wire connection 11 has a common sheath or a bundle of cables for connection with the control module M and has a plurality of branches which connect to each of the elements 80, preferably by a dorsal surface opposite to the contact zone 9 corresponding. Each electrical wire or branch (not shown) is then connected from below the support device 8 to the same end 8b, and then connected to the control module M, here through the sheath common to all the son. This wired connection 11 makes it possible to circulate the information and the electrical energy between the elements 80 and the control module M.
    FIG. 5 illustrates a circuit diagram that can be used in the control module M, for example inside the housing 14 shown in FIG. 4. Among the electrical components of the control module M, there is a processing unit 15, for example in the form of a processor or a microcontroller, detection means 16 configured to selectively and periodically test the state of use of the contact zones 9 and a switching device 17.
    Optionally, the switching device 17 may comprise quadruple half-bridges HB ("halfbridges"), each of which makes it possible to drive four elements 80. Resistors R are optionally provided between the element 80 and the one or more switching elements. of the switching device 17. Thus the processing unit 15 can independently drive each of the elements 80 and change them from a low potential (for example 0V) to a high potential (for example 5V). Of course, any type of switching element, arranged between the control module M and the contact zones 9, can be used in order to distribute current in these contact zones 9 from the same power supply source. link with the control module M. The processing unit 15 can also manage a data link enabling it to drive ADC converters (it can be a data bus with communication according to a master-slave scheme) each serving to measure the intensity output by the elements 80 and then return a signal or information representative of this intensity to the processing unit 15, when requested. Such ADC converters are here detection means 16. Optionally, these ADC converters can be integrated on one or more microcontrollers that are part of the processing unit 15.
    It is understood that the processing unit 15 can thus drive test elements (for example in the form of ADC converters) distributed in parallel and each associated with one of the contact zones 9. The detection means 16 which include such test elements can make it possible successively to determine, for the contact zones 9, a state of charge to be maintained and a state ready to charge, as a function of a response of each of the test elements associated with the same group of contact zones 9.
    In an exemplary embodiment, the processing unit 15 recovers, thanks to the ADC converters, the intensities discharged by each element 80 of the same group. Here, a group consists of a set of cut elements 80, conductors, belonging to the support device 8 and which are sufficiently far apart that whatever the configuration, each adapter 3 (which has the predetermined distance c between the terminals B1 and B2) can not be connected to two elements 80 of the same group.
    Before measuring an intensity, the processing unit 15 turns on (from 0 to 5V for example) simultaneously the elements 80 belonging to the same group during a course of time allowing the intensity measurements to be recovered. The processing unit 15 will then test each of the intensities obtained and deduce if it corresponds to a resistance equivalent to that of a device 4. Thus, by a test, we deduce for this group which elements 80 already connected to 4. If this is the case, the high voltage is maintained on the corresponding element 80. Otherwise, the element 80 is brought back to the low voltage.
    In another version, the processing unit 15 may be configured to turn each element 80 independently in a cyclic manner with a random frequency but greater than a constant. The tests are also done independently. Thus, in the case where two elements 80 connected to the same adapter 3 are tested at the same time, this would make the test false-negative but the random frequency of these tests would allow a near assured shift of these tests to the next cycle.
    More generally, the processing unit 15 can deduce by one or more appropriate tests whether a battery or equivalent autonomous means of an electrical or electronic device 4 is connected. In the illustrated case, the processing unit 15 then leaves all the outputs of the half-bridges HB (or other elements of a switching device 17) corresponding to the elements 80 that have had a positive test and extinguish them in a functional state. other.
    In the diagram of Figure 5, the ADC converters measure the intensity typically output through the output voltage drop, but this could also be done via Hall effect sensors. It is understood that this type of function can be performed differently.
    More generally, the control module M is able to automatically modify the configuration of the switching device 17, so as to: - stop the power supply to make the contact zones 9 still in the idle state a functional state without the state of use determined by the detection means 16 corresponding to the state of charge to be maintained, and selectively energizing the contact zones 9 hitherto maintained in the inactive state and for which the state of use determined by the detection means corresponds to the state ready to load.
    It is understood that the control module M distributes the right amount of energy on the support device 8 at the right time. It is in this control module M that the intelligence of the system 1 is located. As clearly visible in FIG. 4, this control module M is connected to the support device 8 at one end (output interface of the module M). and to a power outlet at the other end (power supply input).
    In the non-limiting example shown, it is allowed to keep the elements 80 in an inactive state and turn on one of these elements 80 only for a very instant course, of the order of one millisecond. The system 1 is therefore very efficient in standby. In operation, the batteries of the apparatuses 4 are connected to the contact zones 9 formed by the elements 80 via an electrical conduction contact, which makes it possible to have performances very close to the conventional charger but with the possibility of simultaneously recharging a wide variety of devices 4.
    Of course, the activation mode of the elements 80 may change as needed. The detection means 16 can thus be configured differently, in particular (and in a nonlimiting manner) if the support device 8 comprises a low number of contact zones 9. Detection without forming groups of elements 80 may for example be performed. For this, it suffices for example to use several modules (for example processors) each capable of independently ensuring the testing of each element 80, each having its own process.
    Although the examples in Figures 2 and 4 show square-shaped contact areas 9, a hexagon shape or other shapes can be used with the same kind of distribution and the same narrowness of insulation spacings. variants, the contact areas 9 are staggered and / or comprise at least two distinct types of format.
    For a substantially square format of the contact areas 9, at least in one of the rows, the predetermined distance c which separates the two input terminals B1, B2 may satisfy the following relation with respect to the side a of the contact areas:
    Indeed, it is not useful in practice for the distance c, defined by the strip B between the input terminals B1 and B2, to be too long compared with a characteristic size of the contact zones 9. here a good compromise since it allows all the same terminals Bl, B2 not to come into contact with the same square contact.
    Adapter
    While the electricity distribution system 1 may have a variety of options for the stationary part 2, an adapter 3 is provided according to the invention, the geometry of which is particularly suitable for equipping a nomadic device 4 which has a charging port, for example a micro USB type port or the like.
    With reference to FIGS. 1 and 3A-3B, the adapter 3 has an elongated tab or label format thanks to the strip B. The strip B is thin and lengthwise extended by a thicker connector member 20. Preferably, the strip B is flexible and has an optionally constant thickness which does not exceed 2 mm (the thickness being typically greater than 0.001 mm).
    The length of the strip B is typically shorter or equal to the length of the device 4 reloaded. In practice, with regard to the usual screen sizes (at least 3 inches or 7.62 cm) for nomadic devices, the strip B has an apparent length L 2 (visible in FIGS. 3A and 3B) which can be typically between 50 and 120 mm. The predetermined distance c can thus be between 40 and 100 mm in preferred embodiments. A longer strip length B may be provided, especially if it is possible to fold one end of the strip B.
    The strip B may comprise several layers, at least three layers in a preferred option. The lower layer is here flat and covered with an adhesive material (for example repositionable adhesive of a kind known per se or elements with suction effect) for fixing the strip B to the device 4. The adhesive material can be chosen to provide removable and repeatable adhesion a dozen times without loss of adhesion. The upper layer of the strip B defines the outer face F2 and can display information and if necessary one or more logos.
    The lower layer defines the bottom face F1 which is optionally transparent or translucent, as shown in FIG. 3B. The internal face F1 is at least partly adhesive and forms a flat attachment surface, so that the strip B forms a sticker which extends in a longitudinal direction between a distal end 40 and a proximal end, bent and close to the charging port in an assembled state of the adapter 3 on the device 4 to be recharged. The input terminal B2 is here close to the distal end 40, being for example located at less than 20 or 30 mm, preferably less than 12 mm, from the free edge defined by the distal end 40.
    The intermediate layer comprises two electrically conductive strips or lines 18, 19, each connected at one end to one of the conductive input terminals Bl, B2 of the adapter 3, and to the other at the connection elements 22 (FIG. "VBUS" and "GND") of the connector member 20. The latter is made in the form of a micro USB plug if the device 4 is recharged by micro USB. The connector elements 22 are mounted in the strip B in a bent portion 21 of the strip B. It may be noted that these connector elements 22 (defining the connection surface 220) can be located on the side of the internal face Fl, at the difference of the input terminals B1 and B2 located on the side of the outer face F2.
    Although this example shows a strip B which assembles with the connector member 21, where appropriate by a removable attachment, it can alternatively be provided that the connector member 21 is inseparable from the strip B and formed in one piece with the banner B to define the adapter 3.
    Referring to Figure 6, the insertion portion 24 of the connector member 20 allows a rigid attachment, typically on a slice of the device 4 (position generally adopted in electronic devices that have a display screen and some other electrical appliances). The connector member 20 also has a head 25, here bounded externally by a housing, which forms a support of the insertion portion 24, finer. The connector member 20 serves as an electrical power transmission medium between the device 4 to be recharged and the two electrically conductive strips 18, 19 of the strip B.
    To ensure that the current is sent in the correct direction, the adapter 3 may include a component that allows only one direction of current flow between the two terminals B1, B2, in the closed state of the circuit recharge. Even if the phones of last generation are generally equipped with a protection mechanism of a kind known per se preventing a connection that would reverse the polarity of the batteries (the device would not charge in such a case), this type of component such that a diode for a one-way operation makes it possible to ensure the good direction of the current, so that the device 4 charges each time even if it is a device without protection mechanism. For example, one can incorporate such a component in the connector member 20. Furthermore, a voltage stabilizer can also be incorporated, to ensure optimum voltage on all devices 4.
    In one embodiment, the conductive strips 18, 19 are composed of metallic materials. The input terminals B1 and B2 are typically in the same material and / or include a coating with high electrical conductivity (copper, silver, some alloys such as silver-cadmium, copper alloy and / or gold can agree without being limiting).
    The lower and upper layers are composed of flexible and non-conductive materials, for example paper or a flexible polymer. Thus, with the exception of the two input terminals B1, B2, the external face F2 consists of an electrically insulating coating. It is thus understood that more than 90 or 95% of the outer face F2 consists of an electrically insulating coating.
    Of course, the system 1 may comprise a plurality of adapters 3, which preferably are identical. As illustrated in the drawings, each adapter 3 may have a number of input terminals B1, B2 exactly equal to two and forming two surface portions PSI, PS2 spaced apart by the predetermined distance c and which form part of the outer face F2.
    As clearly visible in FIG. 2, the predetermined distance c is at least three times greater than the largest extension of any of the two surface portions PSI, PS2 shown in FIG. 3A. For portions PSI, PS2 of circular or substantially circular section having a diameter DC, the distance c can typically be of an order of magnitude greater (for example by being about 10 to 100 times greater than the diameter DC or equivalent maximum extension when the PSI, PS2 portions are not circular). The bent portion 21 may comprise a predefined fold line 26 formed at the end of the strip B which rigidly assembles with the connector member 20 and a restriction zone in width ZP able to deform and bend and which facilitates the forming one or two additional fold lines 31, 32, as visible in FIGS. 1 and 3B.
    The restriction zone ZP can thus extend transversely to the longitudinal direction of the strip B when the latter is attached by its internal face F1 to a flat dorsal face 6 of an apparatus 4. The central axis X visible in FIG. 3B can define such a longitudinal direction. In a non-limiting manner, the restriction zone ZP here essentially extends on one side only with respect to the central axis X, which makes it possible to form a long edge 33 that is substantially straight. Such a long edge 33 facilitates for the user the attachment of the inner face Fl in the longitudinal direction of the central axis X, which avoids in practice to create a twist of the restriction zone width ZP.
    The strip B shown in FIGS. 3A-3B, before mounting on a device 4, may be flat and it is the junction with the bent portion 21 which forms the predefined fold line 26. Alternatively, at least one other fold line 31 and / or 32, parallel to the fold line 26 may be formed before a first assembly on a device 4 to recharge.
    The ZP zone which corresponds to a narrowing is optional and may have a different format from the case illustrated in Figures 1 and 3A-3B. In addition, the number of terminals on the strip B may vary depending on the need. Thus, the strip B may have more than two contact terminals B1, B2, for example if one wants to charge laptops whose battery has a high capacity (for example with a much higher number of cells compared to a battery phone).
    For a recharge of more powerful devices, the adapter 3 can optionally combine several strips or conductive lines 18, 19 in the same strip B having larger dimensions. In this case, a greater number of contact zones 9 feed the same strip B which is perceived by the support device 8 as representing several bands. Thus, an adapter provided with a strip B which has more than one pair of contact terminals can be perfectly adapted to reload a relatively powerful device 4.
    The output terminals of the strip B, formed by the connector elements 22, protrude from an inner face of the strip B and are oriented in a direction substantially perpendicular to the orientation of the two input terminals B1, B2, so that the strip B keeps a planar configuration of the outer face F2 when the adapter 3 is attached to a back surface 6 of a device 4 and connected to a charging port of the same device 4 by the connector member 20 .
    Referring to Figure 7, the head 25 of the connector member 20 may be rigid and is extended by an insertable portion 24 of removable connection, for example micro-USB type. The terminals 201, 202 formed in the head 25 are arranged at the bottom of cavities which correspond to the projections formed by the connector elements 22 in the bent portion 21. This bent portion 21, rigid and which may include an L-shaped section of ferromagnetic material covers the rear face 28 of the connector member 20.
    The ferromagnetic material present in the bent portion 21 completes the connection elements 22 here to define attachment means which allow detaching the strip B. Magnets may optionally be provided (here on the side of the connector member 20), so that the strip B is removably attached to the connector member 20. This arrangement also allows to selectively position the strip B on one side (in a first configuration) or on another opposite side (in a second configuration). It is thus possible to unhook the strip B to turn it over and hang it up, for example by magnetization.
    When the bent portion 21 forms an L, the covering section 21b which covers the rear face 28 is flat, rigid, and perpendicular to the central axis X or other longitudinal direction defined by the remainder of the strip B. The other section 21a , adjacent to the narrower and more flexible ZP restriction zone, may have substantially the same width as the cover section 21b and preferably has a stiffness similar or identical to that of the cover section 21b.
    The bent portion 21 is advantageously connected to the head 25 opposite the insertable portion 24, which facilitates the miniaturization of the head 25. The strip B comprises a position adjustment portion which corresponds to the restriction zone. ZP width, this adjustment portion being delimited between the first fold line 31 of the strip B which is proximal relative to the connector member 21 and the second fold line 32 which is distal. The adjustment portion makes it possible to offset the bent portion 21 with respect to the plane attachment zone defined by the internal face F1. The longitudinal dimension of the zone ZP defined by the adjustment portion can be of the order of 5. at 15 or 20 mm (dimension measured along the central axis X before folding).
    Although the figures show an adapter 3 only connected to the device 4, one can alternatively connect an accessory to the adapter 3. Thus, when the device 4 is equipped with interchangeable shells (which allows customization), the adapter 3 can: either cover the shell by its internal face Fl (where the face 6 can be defined by a shell integral with the adapter 3), or partly be incorporated in a shell which completes the device 4 ( case of a shell that is removable with the adapter 3).
    More generally, it is permitted to extend the strip B and / or the connector member 20 to perform additional functions. At least one end of the adapter 3, distant from the contact zone where the terminals B1, B2, are located, can thus comprise a complementary element which covers or extends close to another face of the apparatus 4.
    Installing the adapter and charging
    Referring to Figures 1 and 6-7, the process of installation of the adapter 3 on the device 4 by the user is as follows: the user first plugs the insertable portion 24, here a micro plug USB in the example of Figure 6 (or other if the device 4 is not recharged by micro USB), in the socket forming the charging port of his device 4, then fold the flexible B-band back of the one (See Figures 1 and 7 showing a conformation of the adapter 3 which is well adapted so that the strip B is fixed in the manner of a label or sticker).
    With reference to FIG. 1, this strip B adheres by its internal face F1 to the dorsal face 6 of the appliance 4 thanks to the adhesive of the lower layer. In the installed state, the input terminals B1 and B2 are arranged in the same plane, on the outer face F2 with an alignment that may be substantially parallel to the central axis X or similar longitudinal direction.
    Referring to Figure 4, once the adapter 3 and installed on the device 4, the user can reload it by placing it on the charging surface 5 with the use face (face to screen and / or to user interface) upwards, which makes it possible to position the external face F2 of the strip B downwards. The two conductive input terminals B1, B2, which here are two metal circles of small size (between 0.001 mm and 5 mm, for example), each reside on a different contact zone 9. The contact areas 9 here have the shape of a square but the cutting of the elements 80 may of course be different.
    Referring to Figure 4, each support device 8 is configured, in normal times, so that the charging surface 5 is connected to ground. It is typically the mass of the circuit which is itself connected to the mains mass. It is possible to provide a controlled switch or similar switching device, for example positioned on the printed circuit board of the control module M, which makes it possible to connect each cut-out element 80 to the required voltage independently of the other elements 80.
    According to a time interval, the switch briefly branches element 80 to the nominal voltage. The equivalent resistance between this element 80 and the mass is then measured. If it corresponds to that of the device 4 provided then the voltage is always sent. A cyclic measure of equivalent resistance begins. During the first measurement or cyclic measurements after a first verified test, if the equivalent resistance no longer corresponds to that of the device 4 provided, then the switch is placed back on the ground. This solution makes it possible to ensure that as soon as a device to be recharged 4 is put on the recharging surface, the good contact zone 9 of an element 80 goes to the high potential.
    By default, the control module M ensures that all the elements 80 remain at the low potential. Only the adapter 3 installed on a device to be recharged 4 can activate the power distribution. The ADC converters take care of the measurements, while a microcontroller or similar processing unit processes these measurements and controls them.
    When the control module M has detected the presence of the assembly formed by the adapter 3 and the device 4 on the charging surface 5 and identified the good contact areas 9, it controls the switching device 17 to deliver the current required to recharge the device 4. Only the two contact zones 9 which are in contact with the input terminals B1, B2 are lit, after a verification by the processing unit 15 that the state of these contact zones 9 corresponds to the "ready to charge" state.
    The current flow between the contact areas 9 of the charging surface 5 and the two input terminals B1, B2 conductive adapter 3 is made by contact, with high energy efficiency.
    In one embodiment, the test elements that enable the detection of the operating state of the elements 80 forming the contact zones 9 are configured to periodically and very briefly control such a state. The tester elements are, for example, electrical signal converters. It will be understood that the control module M makes it possible to automatically modify the state of the elements 80 to avoid any unnecessary energy expenditure and to recharge a device 4 which has just been placed on the charging surface 5, without any identification step concerning the nature or specific characteristics of the device 4.
    The relative position of the dorsal face 6 of the apparatus 4 with respect to the charging surface 5 is irrelevant to allow charging, since the terminals B1, B2 are well positioned on one of the contact zones 9.
    The separation distance D10 between the contact zones 9 is here slightly greater than the diameter DC of the surface portions PSI, PS2, so as to prevent the input terminals B1, B2 from being in contact with two contact zones 9.
    One of the advantages of the electricity distribution system 1 is its adaptation to a very large number of users (anyone having at least one nomadic electrical or electronic device 4) and to any kind of environment (home or in public places) providing access to the recharge area), with the possibility of freely distributing or marketing the adapter independently for the company or organization wishing to provide target users with such an opportunity to recharge their mobile devices 4 in their premises or in their premises. public spaces. The space available on the outer face F2 makes it possible to play the banner B as a label, so that the adapter 3 can be used to make visual communication around a logo, text or image. other communication elements.
    Once the user has an adapter 3, he can use any corresponding charging surface 5 to recharge his electrical or electronic nomadic device 4. Other advantages include: - the ability to recharge several devices 4 on the same charging surface 5, preferably providing energy optimally from a single electrical outlet 12; the reduced weight of the adapter 3, which is typically much less than 10 g thanks to the fineness of the strip B (whose thickness may be substantially constant at the possible exception of the bent portion, and for example less than or equal to 2; mm); and the low energy cost due to a power control of the contact areas 9 (same charging efficiency as a conventional charger, no energy losses during charging and standby).
    The system 1 can be incorporated into suitable furniture or supports. If necessary, a holding device may be used to permit charging of devices 4 on flat or vertical plane charging surfaces. The device 4 to be recharged is pressed against the charging surface 5 by means of a holding element in position and / or thanks to an elastic return element (for example a spring member) which tends to press the device 4 against the surface recharge. The strip B may optionally be connected, by its end opposite the connector member 20 or by another part, to a fastening member. According to one option, the device 4 can be suspended on a wall, a piece of furniture, when the adapter 3 is connected to the support device 8 to be recharged and / or powered.
    The devices to recharge 4 are not limited to phones and other nomadic communication devices. Digital photography devices, PDA (Personal Digital Assistant), portable computers, digital headsets, wireless mice, robots, chargers or toys with batteries, provided they have a relatively flat surface or suitable support surface close to a charging port, are also suitable for recharging by the electricity distribution system 1, using the adapter 3 embedded. It is thus understood that the charging surface 5 may be suitable for powering and / or recharging: appliances of small household appliances equipped with the adapter 3, and the "objects" said "connected": watches, bracelets, sensors, textiles (existing objects and coming).
    It should be obvious to those skilled in the art that the present invention allows embodiments in many other specific forms without departing from the scope of the invention as claimed. Thus, the strip B or tab is not necessarily integral and may, in variants, be broken down into several parts assembled together using any suitable method of attachment, the snap corresponding to a preferred option (but non-limiting).
    The relative position of the strip B relative to the apparatus 4 may be different, for example by using a foldable or specifically articulated part (which may optionally constitute a foot for placing the apparatus 4 at an angle of the order of 90 ° or less (for example 60 °) relative to the horizontal (in the manner of a photo frame) A position different from the flat position can thus be obtained, with the advantage of promoting the comfort of viewing video for example, the adapter 3 can also be extended by a case or a case that performs a function of storing accessories, for example earflaps.Optionally, the strip B and / or the connector member 20 can be assembled to such a device. In this case, the container may for example include the connector member 20 and extend away from the terminals B1, B2, with a space suitable for not interfering with the charging contacts between the strip B and the charging interface 5.
    Although the figures illustrate the case of a substantially flat face 6 for attaching the strip B, it is understood that the strip B can be hooked differently along one side of the device 4. For example, the outer face F2 of the strip B may be housed, at least in part, in a cavity formed on a face of the device 4 to be recharged (which may allow to partially border the strip B; in such a case, the thickness of the strip B does not necessarily add to the thickness of the device 4).
