    The invention relates to a charging unit for charging a vehicle, the charging unit having an insertion device with at least one pivotable insertion funnel and a first contact arranged therein for electrical connection to at least one further contact along a connection axis
    having.
    Such charging units can be installed in the vehicle that is to be charged or can be arranged at a charging station such as a charging station. A charging station in the former case or the vehicle to be charged in the second case can connect to the charging unit for charging. In this way, a connection can be established between a charging station that provides electricity and the vehicle that stores the electricity.
    Such charging units are accordingly particularly important for electrically powered cars such as pure electric vehicles or vehicles with more than one type of operation such as hybrid vehicles, since these vehicles regularly have to absorb larger amounts of energy in the form of electricity. For this purpose, the vehicles are usually first brought close to the charging station and positioned appropriately to the charging station, so that another contact can then connect to the first contact. This connection is preferably made automatically or semi-automatically, so that the driver can no longer get out or look around
    Connection must take care of.
    The insertion device serves to at least partially accommodate a further contact so that it can connect to the first contact. The further contact can be arranged, for example, on a charging cable or on a similar transmission medium.
    US 2011/300738 A1 and US 5,462,439 A1 describe loading units which have loading funnels in order to center automatically movable further contacts in the loading unit if the vehicle is arranged slightly offset from the loading station. This enables an expansion of the parking area of the vehicle in which a connection is still possible. However, this area is still very small and the second contact with the charging funnel can tilt, which means that a complete connection is not possible.
    This is very uncomfortable because this is only connected by further connection attempts or even moving the vehicle, which makes the connection process lengthy and cumbersome for the user of the vehicle.
    DE 10 2001 082 092 A1 describes a loading system with a loading unit, which has a pivotable insertion funnel. This allows the insertion funnel to pivot in the direction of the further contact in order to facilitate the connection to the first contact and to expand the effective range of the insertion funnel. In this case, however, the further contact or a part connected to it can jam or jam with that of the loading unit, which prevents the connection. Since the connection is very susceptible to errors when using conventional, standardized contacts, specially shaped contacts must be provided in order to enable a better connection. However, this is not very advantageous since the production is so expensive and complicated and there are compatibility problems with vehicles with widespread, standardized connector types.
    The object of the invention is thus to avoid the disadvantages described and to provide a loading unit which has a reduced risk of canting when
    Connect with the further contact.
    This object is achieved in that at least one guide element is arranged in the region of the first contact and that
    Guide element is movable at least along the connecting axis.
    The spring-loaded guide element further centers and aligns the further contact in relation to the first contact, so that they are directly opposite and can easily connect to one another. This is particularly advantageous in the case of plug-in connections, since this facilitates sliding into one another. The guide element can have a wide variety of shapes.
    The connection axis is defined by the first contact and is the axis along which the first contact and the further contact connected to it must be moved to one another in order to be able to produce an optimal electrical connection of the contacts with the least possible risk of jamming or jamming. In the case of a plug-in connection, this connection axis is usually defined by the
    Direction of the pins, or openings in which the pins are inserted, specified. In the case of a connection without an electrically conductive contact, for example in the case of inductive transmission, the optimal inductive coupling is achieved when the further contact is aligned with the first contact along the connection axis. As a rule, this connecting axis points straight out of the insertion funnel, since the first contact is arranged centrally in the center of the insertion funnel, that is to say at its narrowed point.
    The insertion funnel does not have to taper uniformly, but can have different slopes, courses or plateaus in different directions. It can be pivoted about an axis or a gimbal
    Have storage and thus be pivoted in several directions.
    In the area of the first contact, it is meant that the guide element is spatially close to the first contact, although it does not have to be directly adjacent to it. The guide element can, for example, be designed as part of the insertion funnel or as part of the first contact. It can be moved and / or sprung along the other axes beyond the connecting axis
    be.
    It is advantageous if the first contact is connected to the guide element. It is particularly advantageous if the first contact is immovably connected to the guide element. The guide element and the first contact can be made in one piece. The first contact is thus also spring-loaded and can be moved - preferably in a limited space - when loaded by the further contact. This simplifies the construction and improves the connection of the contacts to one another. In particular in the case of a plug connection, when the further contact approaches, the first contact can first be pushed a little away from it and moved deeper into the insertion funnel if the optimal relative position to one another has not yet been found. This favors centering and adjusting the contacts to one another. If the contacts face each other in such a way that a connection is possible, they can, if provided by the type of contacts, at least partially slide into one another and thus establish the connection. The first contact may move back.
    If the first contact is connected to the insertion funnel via at least one spring of the guide element, the construction can thus be further simplified. Several springs can be provided, which, for example, in
    Are arranged substantially uniformly around the circumference of the guide element,
    to allow good suspension.
    In order to enable improved guidance of the further contact, the guide element can be pivotable in relation to the connection axis. The guide element can be pivoted about an axis transverse to the connecting axis
    or about two axes.
    Alternatively, it can also be provided that the guide element is guided in a translatory manner along the connecting axis. This means that the guide element can be moved along the connecting axis, but it cannot be pivoted in relation to this axis. This can be particularly advantageous when aligning the further contact in relation to the first contact. In particular with a plug connection, the alignment of the axes of the female and
    male contacts to each other can be achieved.
    In order to prevent uncontrolled movement out of the insertion funnel, it can be provided that the guide element has at least one shoulder, and the shoulder limits the movement of the guide element in the direction of an insertion recess of the funnel. The shoulder can be on a corresponding shoulder of the insertion funnel in a maximally extended
    Position.
    It is particularly advantageous if the guide element is at least partially arranged between the first contact and the insertion funnel. The alignment of the axes of the contacts with one another can thus be designed particularly effectively.
    It can also be provided that the guide element is arranged essentially around the first contact. The guide element can also not be connected to the first contact. A plurality of guide elements can also be provided, which are around the first contact
    are arranged.
    In order to further improve the guidance of the further contact, the guide element can protrude into an insertion recess of the insertion funnel in a relaxed position. The insertion recess is understood to mean that part of the insertion funnel which at least largely tapers and thus mainly assumes the function of guiding and guiding the further contact. If the guide element projects into this area, the axis of the further contact can be supported while it is being positioned
    the insertion recess is improved.
    For better guidance of the further contact, it can also be provided that the guide element has at least one guide surface, at least in sections
    is inclined towards the first contact.
    In order to ensure a stable and simple design, the guide element can be connected to the insertion funnel via at least one spring
    be.
    It can also be provided that the first contact with the insertion funnel is rigid
    connected is.
    To protect against contamination, it can be provided that the insertion device has at least one movable flap for covering at least the first contact
    having.
    Charging devices are particularly advantageous which have a charging unit of the type described and such a charging device has at least one movable arm with a second contact for electrical connection to the first contact. This second contact can connect as a further contact to the first contact and thus establish a connection between a vehicle and a charging station. The charging device can preferably be arranged at the charging station, such as a charging station, while the arm is preferably
    is arranged on the vehicle. Reverse arrangements are also possible.
    It is also advantageous if the first contact is designed as a socket and the second contact as a plug. With this, a plug connection can be easily established, which represents a stable and simple connection over the large quantities
    of energy can be transferred in a short time. Alternatively, the first one
    Contact as a plug and the second contact as a socket. Socket is understood to mean the external contact of a plug connection into which the plug is inserted.
    In order to enable energy transmission to be as safe as possible, it can be provided that the first contact and the second contact are designed for this
    are to transmit energy without contact, preferably via an inductive coupling.
    Alternatively, the first contact and the second contact can also have electrical contact surfaces for connection to one another. This enables a particularly high energy transfer rate.
    In order to enable better centering of the second contact, the arm can preferably have a section in the region of the second contact that is flexible. This makes it easier to insert the arm into the insertion funnel.
    In order to reduce the space requirement of the arm, the arm can at least partially be designed as a push chain. The push chain can be rolled up in the de-energized state, but can transmit thrust and compressive forces under tension. In this sense, it is particularly advantageous if the push chain has at least two links connected to one another, a first link having at least one first connecting surface arranged essentially transversely to a main axis of the push chain and a second link at least one second link arranged essentially transversely to the main axis of the push chain Has connecting surface, wherein the first connecting surface and the second connecting surface are formed in a linear position one above the other
    to be arranged and to rest on each other.
    In order to simplify the positioning of the vehicle in relation to the charging station, the charging device can have a positioning system for aligning the arm and insertion device with respect to one another, and the positioning system can have at least one laser. The lasers can simplify the fine positioning of the vehicle to the charging station, preferably automatically or semi-automatically.
    Alternatively, the laser can also be arranged on the arm side.
    It can be provided that the second contact has a pyramidal body
    has, the tip or stump preferably pointing away from the arm.
    Alternatively, standardized connection types such as the connector type ICE 62196 type 2 can also be used. Accordingly, the first plug can also have a socket corresponding to it.
    The arm is preferably movable along one of its main axes. It is particularly advantageous if the arm can be moved by a motor at least along a main axis of the arm. This allows the arm to be retracted and extended by a motor,
    to connect the contacts.
    In order to ensure a better connection, it can be provided that the arm is flexibly mounted transversely to a main axis. So the arm can swing out
    if the contacts are staggered.
    The present invention is explained in more detail below on the basis of a non-restrictive embodiment variant shown in the figures. It
    demonstrate:
    Figure 1 shows part of an embodiment of an inventive
    Insertion funnel in a schematic perspective view;
    Figure 2 shows the insertion funnel in a schematic perspective view;
    Figure 3 shows a rear part of the loading unit in a schematic perspective view;
    Figure 4 shows an insertion device according to the invention in a side view.
    Fig. 1 and Fig. 2 show an insertion funnel 3 according to the invention, which is pivotally gimbal-mounted. This has an insertion recess 4, which initially remains the same width and height from an essentially square insertion opening 5 into the interior of the insertion funnel 3 and then tapers substantially uniformly. At the end of the insertion recess 4 opposite the insertion opening 5, the insertion funnel 3 tapers in a curved and particularly strong manner before the insertion recess 4 opens into a supply recess 6. This ends at the opposite end of the insertion funnel 3. In the supply recess 6 there is a first one designed as a type 2 E mobility connector
    Contact 7 used, which is only shown schematically. The elongated plug
    is connected on its outer sides to a guide element 8 and is made in one piece with it, the guide element 8 having a shoulder 10 at the end remote from the insertion opening 5, which limits the penetration of the guide element 8 and the first contact 7 into the insertion recess 4. The guide element 8 together with the first contact 7 has a cross section which, with the exception of the shoulder 10, fits snugly with the cross section of the supply recess 6. The first contact 7 can thus be moved in translation along a connecting axis A. The first contact is designed as a socket and has an end face 12 for connection to a further contact, which is normal to the connection axis A and into which
    Insertion recess 4 shows.
    The guide element 8 is connected via four springs 9 to the insertion funnel 3, whereby this is pushed in the unloaded position in the direction of the insertion recess 4 until the shoulder 10 is pressed against the corresponding shoulder of the insertion funnel 3. This unloaded position is shown in Fig. 2. The guide element 8 and also the first one protrude
    Contact 7 into the insertion recess 4.
    The first contact 7 is electrically via cables, not shown, via the
    Supply recess 6 supplied.
    The insertion funnel 3 has a front part 13 and a rear part 14, which are screwed together. In Fig. 3 only the rear part 14 is shown, which shows that the supply recess 4 at the end remote from the insertion opening 5 is reduced in cross section. This releases a surface that is normal to the connection axis A and on which the springs 9 can engage. This area also limits the movement of the guide element 8 away from the
    Insertion opening 5.
    4 shows a charging device which has an insertion device 1 for installation in a charging unit such as a charging station of a charging station and a movable arm 15 for installation in a vehicle. The insertion device 1 has a loading funnel 3 similar to the embodiment shown in FIGS. 1 to 3, which is movable in a suspension 11 once around a first pivot axis S1 and once around a second pivot axis S2
    is pivotally mounted. This results in a cardanic bearing for the
    Loading funnel 3. Both swivel axes S1 and S2 are normal to the connecting axis A. This allows the insertion funnel 3 to be swiveled by approximately 30 ° in any direction. In other embodiments, a smaller or larger angle can be selected. 4, the insertion funnel 3 is shown in a neutral, not swiveled out position.
    The arm 15 has a rigid main arm 16 which is connected to a motorized entry device 18 via a toothed rack 17. The arm 15 can thus be displaced linearly along a main axis B and thus pushed out of a covering of the vehicle from a storage position in the interior of the body into an active position. He protrudes at least partially in the active position
    out of the vehicle and can connect to the insertion unit 1.
    At the end further from the vehicle, ie the end facing the charging funnel 3, a connecting head 19 is arranged, which has an elastic section 20. In this embodiment, this elastic section 20 is designed as a spiral spring. A second contact 21 is arranged on the elastic section 20 at one end of the arm 15 and has a substantially truncated pyramid-shaped body 22 which extends along an intermediate axis C. The intermediate axis C is also the axis on which, should the second contact 21 be displaced along this, the risk of canting or of getting stuck when connecting to the first contact 7 is particularly low. In the illustrated, unloaded position of the arm 15, in which no significant forces act on the second contact 21, the main axis B and the intermediate axis C are the same axis.
    In Fig. 4 the optimal case is shown in which the main axis B and the connecting axis A are the same axis. In other words, the vehicle is optimally positioned in relation to the charging station, so that a connection between the first contact 7 and the second contact 21 can be established by the linear extension of the arm 15. Since the second contact 21 is not loaded transversely, the intermediate axis € is also axially aligned with the connecting axis A. But if the vehicle is slightly offset, the main axis C and connecting axis A are no longer the same axis and they may also no longer be parallel to each other. If the main arm 16 is moved by the insertion device 18 in the direction of the insertion device 1, then
    in this case the second contact 21 meets due to a displacement between
    Connection axis A and main axis B are not centered on the insertion funnel 3. The elastic section 20 can thus bend and the second contact 21 can be guided in the direction of the first contact 7. If the second contact 21 meets one or more guide elements 8, this is guided further to the first contact 7 by the elastic guide and / or its intermediate axis 21 is aligned in accordance with the connecting axis A, so that these become parallel and / or axially identical. This will bring together the first and second
    Contact 7, 21 optimally achieved.
