    The invention relates to the field of ventilation, heating and / or air conditioning installations. The invention relates in particular to a motor-fan unit including such an installation.
    A heating, ventilation and / or air conditioning system of a vehicle, in particular an automobile, is generally used to distribute air into the passenger compartment of the vehicle. In such an installation, the circulating air flow is propelled by a motor-blower unit also called blower, comprising in particular a blower wheel and an electric motor adapted to rotate the blower wheel.
    The motor-fan unit also comprises a motor support, secured to a housing of the heating, ventilation and / or air conditioning system, suitable for carrying the motor of the fan motor unit.
    Conventionally, the motor is controlled by a control module comprising in particular a control circuit for powering the motor windings and an electrical connector allowing in particular to bring the energy to the control circuit and / or control signals. According to a known solution, a control module support carries this control module. It is known that this control module support also provides the bearing support function for the motor.
    In order to allow assembly of the motor-fan unit, the motor support and the control module support are generally assembled together in a fixed position, with the electrical connector being able to extend parallel or orthogonally with respect to extension planes. main motor support and control module support that are parallel to each other. For reasons of space, the electrical connector preferably extends parallel to the main extension planes of the motor support and the control module support. In addition, the electrical connector extends in a fixed direction relative to the housing on which the motor-fan unit is mounted.
    The designers usually make the prior choice to allow mounting of the motor-fan unit on the motor vehicle with a specific predefined orientation of the electrical connector according to the application. The installation of the motor-fan unit on the vehicle housing must take into account several parameters such as in particular the risk of water intrusion in the electrical connector of the control module, the space requirement, or the assembly of the motorcycle unit. in the vehicle in particular the connection of the electrical connector to the vehicle harness. Indeed, it is preferable that the motor-fan unit is arranged so that the electrical connector is oriented downwards according to the arrangement on the vehicle to avoid water intrusions. Furthermore, on the assembly line, an operator must be able to easily access the electrical connector, so it is important that cables or other connectors do not prevent the operator from accessing the electrical connector of the engine control module of the group. fan motor.
    According to known solutions, the motor-fan unit is designed specifically for each application, so as to comply in particular with an orientation of the specific electrical connector, which is a critical point for integration on the vehicle.
    Consequently, for each type of heating, ventilation and / or air conditioning system, it is necessary to adapt the entire motor-fan unit. In particular, the motor support, or more precisely the interface of the motor support with the vehicle housing, must be modified. Or it can be a complicated piece whose redesign and / or modification can be long.
    The lack of flexibility proves to be restrictive and requires the assembly of the motor-fan unit exclusively according to a specific choice previously defined according to the needs of the car manufacturer. The invention therefore aims to at least partially overcome these problems of the prior art by providing a motor-fan unit whose assembly and mounting on the vehicle can be adapted to the needs of the car manufacturer. To this end, the subject of the invention is a motor-fan unit, in particular for a heating, ventilation and / or air-conditioning installation of a motor vehicle, comprising: a motor, an engine support, and a module support. bearing support arrangement for the motor, characterized in that the motor support and the control module support each comprise at least one attachment zone, the fixing zones being able to cooperate with one another for the assembling the motor support to the control module support in at least two different positions of the motor support relative to the control module support.
    In other words, the fixing areas of the motor support and the control module support are configured so that the motor support and the control module support can be assembled to each other in at least two different positions.
    The motor is in particular a brushless motor or electrically commutated motor.
    Thus, there are at least two, preferably three, possible assembly positions between the motor support and the control module support. During assembly, it is possible to define the orientation of the motor-fan unit relative to the vehicle casing and consequently in which position to assemble the motor support and the control module support.
    Each attachment area includes all mounting features for assembling the motor mount to the control module mount. In particular, the attachment zones may be able to receive one or more mounting elements which may be chosen from: screws or screw-nut assemblies, or even rivets. Alternatively or in addition, the assembly can be done by deformation of material at the complementary fastening areas vis-à-vis.
    According to one aspect of the invention, the motor support and the control module support have parallel main extension planes, and the attachment area of at least one of the supports is invariant by rotation of a predefined angle. around an axis substantially orthogonal to the main extension planes.
    Advantageously, the attachment zones of the two supports, that is to say the motor support and the control module support, are invariant by rotation of a predefined angle around the axis substantially orthogonal to the main extension planes .
    The two groups of parts respectively carried by the motor support and the control module support can rotate relative to each other to be placed in the selected assembly position.
    According to an additional aspect of the invention, the predefined angle is 120 °.
    According to a further aspect of the invention, at least one attachment area of the motor support and / or the control module support comprises at least two sets of mounting elements.
    According to a particular aspect of the invention, each set of mounting elements is the image of another set of mounting elements by rotation of the predefined angle around the axis substantially orthogonal to the main extension planes .
    The control module support and the engine support can thus be assembled to one another in several positions and the assembly is done with several attachment points, which increases the robustness of this assembly.
    Preferably, the motor support has three sets of mounting elements and the control module support also has three sets of mounting elements.
    Thus, the motor support and the support of the control module can be assembled in three different assembly positions, which makes it possible to meet different needs with regard to the implementation of the motor-fan unit on the vehicle, in particular with respect to the orientation of an electrical connector that would be carried by the control module support. In addition, with three attachment points between the motor support and the control module support, the assembly is robust.
    According to a further aspect of the invention, the sets of mounting elements of a fixing area of a support are distributed in a constant angular offset. Advantageously, the sets of mounting elements of the motor support and the control module support are three in number and are distributed at an angular offset of the order of 120 °. This ensures a sufficient number of assembly positions between the engine support and the support of the control module to meet the needs of implantation on the vehicle, while ensuring a robust assembly.
    This configuration is advantageously adapted to a substantially circular shape of the motor support and the control module support.
    According to a preferred embodiment, the motor control module comprises at least one electrical connector extending substantially parallel to the main extension plane of the control module support, and the attachment zones of the motor support and the module support. are configured so that the electrical connector extends in a separate direction in each of the mounting positions of the motor bracket and the control module bracket.
    The electrical connector arranged parallel to the extension planes of the motor support and the control module support saves space. In addition, the invention makes it possible to have at least two, preferably three, different positions of the electrical connector without the need to modify the parts of the motor-fan unit. There is no need to redesign the engine mount for example to adapt the motor-fan unit in terms of orientation of the electrical connector once assembled to the vehicle.
    According to a particular embodiment, the control module support carries a control circuit, and the fixing area of the control module support comprises mounting elements arranged jointly on the control module support and on the circuit. control. In other words, associated mounting elements are arranged both on the control module support and on the control circuit.
    According to another aspect of the invention, the attachment regions of the motor support and the control module support have complementary mounting elements, at least some of which are configured to allow attachment of the motor support to the control module support and are selected from the following list: screws, nut sets, rivets, orifices, fixing studs.
    According to yet another aspect of the invention, the control module support carries a control module comprising a predetermined number of terminals connected to the motor, and the attachment areas of the motor support and the control module support have elements of the control module. complementary assemblies, at least some of which are configured to allow the terminals to pass through the motor support and the control module support.
    According to another aspect of the invention, the control module support comprises first openings for the passage of terminals, the first openings being the same number as the terminals. The motor support comprises second openings for the passage of the terminals, the number of which is determined according to the number of terminals and the number of possible assembly positions between the motor support and the control module support.
    The motor-fan unit comprises for example three terminals connected between the control module and the motor, and the motor support and the control module support can be assembled to one another in three different positions. The engine support comprises according to this example six second openings for the passage of the three terminals according to the three assembly positions between the motor support and the control module support.
    According to a particular embodiment, the motor support comprises protruding portions with respect to the engine support and extending towards the control module support, the said protruding parts having the second openings for the passage of the terminals, and the support control module further comprises cavities in which open certain parts projecting from the engine support.
    Thus, on the one hand the projecting portions of the motor support which are traversed by the terminals open into the first openings of the control module support, while on the other hand the protruding portions of the motor support not traversed by the terminals open in the corresponding cavities of the control module holder.
    Advantageously, the control module support comprises a cooling means of the control module, such as a cooling radiator, which makes it possible to evacuate and / or dissipate the heat produced by the components of the control module. The invention also relates to a heating, ventilation and / or air conditioning system for a motor vehicle characterized in that it comprises at least one motor-fan unit as defined above.
    Thus, one and the same motor-fan unit can be assembled in different positions relative to said installation, in particular a housing of said installation receiving this motor-fan unit. In particular, the control module support can be assembled to the engine support in different orientations relative to the engine support forming particular interface between the fan motor unit and said installation. Other features and advantages of the invention will emerge more clearly on reading the following description, given by way of illustrative and non-limiting example, and the appended drawings in which: FIG. 1 is an exploded view of a motor-fan unit according to the invention; FIG. 2 is a perspective view showing a motor, a control module and a control module support of the motor-fan unit of FIG. 1; FIG. in perspective of a motor support of the motor-fan unit of FIG. 1, - figure 4 is an exploded view of the motor support and the control module support before assembly, - figure 5a schematically represents a view from above of the control module support assembled to the engine support in a first position; - Figure 5b schematically represents a top view of the control module support assembled to the engine support according to a second In a position different from the first position of FIG. 5a, FIG. 5c schematically represents a view from above of the control module support assembled to the engine support in a third position different from the first and second positions of FIGS. 5a and 5b.

    The following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments may also be combined to provide other embodiments.
    In the description it is possible to index certain elements, in other words one can for example mention a first element or a second element. In this case, it is a simple indexing to differentiate and name elements close, but not identical. This indexing does not imply a priority of one element, compared to another. Such denominations can easily be interchanged without departing from the scope of the present invention.
    FIG. 1 shows an exploded view of a motor-fan unit 1, also known as a blower, for example for a heating, ventilation and / or air-conditioning system fitted to a motor vehicle. The fan motor unit 1 is therefore intended to be mounted on a housing of the heating, ventilation and / or air conditioning system (not visible in the figures).
    In this case, the motor-fan unit 1 is arranged to circulate a flow of air in a duct of the heating, ventilation and / or air conditioning system. Π may be an outside air flow taken outside the passenger compartment, or a flow of air taken inside the passenger compartment called recirculated air flow, or a mixing of an outside air flow and a recycled air flow. The air duct of the heating, ventilation and / or air conditioning system distributes the air flow to outlet openings (not shown) opening in the passenger compartment of the vehicle. For this purpose, the motor-fan unit 1 comprises a motor 3 and a fan wheel 5 intended to be driven by the motor 3, so as to ensure the movement of the air flow. This is particularly a brushless motor 3.
    More specifically, the motor 3 comprises a fixed stator and a rotor movable relative to the stator and adapted to drive the fan wheel 5. In the assembled state of the motor-fan unit 1 for example on a housing of the heating installation , ventilation and / or air conditioning, the stator of the motor 3 is fixed relative to this housing.
    With reference to the exemplary embodiment illustrated in FIGS. 1 and 2, the motor 3 extends around a longitudinal axis A, corresponding to the axis of rotation of the motor 3, and comprises a transmission shaft 4 ' extending along the longitudinal axis A. The transmission shaft 4 is for example arranged substantially in the center of the motor 3. In this example, the transmission shaft 4 protrudes from the motor 3 thus having a free end.
    The motor 3 and the fan wheel 5 are coaxial. The fan wheel 5 is mounted on the transmission shaft 4 of the engine 3.
    According to a particular embodiment shown in Figure 1, the fan wheel 5 has a portion 7 having a substantially bowl shape, this portion is subsequently designated by bowl 7. The bowl 7 is substantially concave shape . In addition, the fan wheel 5 may have a flat portion formed at the periphery of the bowl 7, the side intended to cooperate with a motor support 11 described below. In other words, the bowl 7 ends with this flat. The flat part extends in this example substantially orthogonally with respect to the axis A.
    The fan wheel 5 further comprises a central hub, to receive the free end of the transmission shaft 4 of the motor 3. The fan wheel 5 may have a substantially cylindrical general shape comprising blades or fins 9 which extend in this example from the periphery of the bowl 7, in a direction substantially parallel to the longitudinal axis A of the motor 3. In other words, according to the particular embodiment illustrated, the blades or vanes 9 extend away from the flat at the periphery of the bowl 7 and substantially orthogonal to this flat.
    The fan motor unit 1 further comprises a motor support 11.
    The motor support 11 has a general shape extending along a main extension plane. The axis A is substantially orthogonal to this main extension plane of the engine support 11.
    According to the embodiment illustrated in Figures 1 and 3, the motor support 11 has a generally circular general shape.
    The motor support 11 is for example made of plastic material.
    The motor support 11 defines an internal structure 13 for fixing the motor 3. In the example illustrated, the internal structure 13 defines a central hole.
    Furthermore, the engine support 11 is preferably intended to be mounted on the housing of the heating, ventilation and / or air conditioning system at a volute (not shown) ensuring the channelization of the air flow generated by the fan motor unit 1. Advantageously, the motor support 11 comprises an outer ring 15 which is intended to be fixedly mounted on a housing (not shown) of the vehicle. The motor support 11, and in particular the outer ring 15, forms in this example an interface between the motor-fan unit 1 and the vehicle, including the heating, ventilation and / or air conditioning system of the vehicle.
    In addition, the motor support 11 has in this example an upper face 11a and an opposite lower face 11b. The lower face 11b of the engine support 11 is here arranged opposite the fan wheel 5 (see FIG. 1).
    The motor support 11 further has at least one attachment zone for assembling the motor support 11 to at least one other element of the motor-fan unit 1 as described below.
    According to the example illustrated in FIGS. 1 and 2, the fan motor unit 1 further comprises a control module 17 of the motor 3.
    With reference to FIGS. 1 and 2, the control module 17 comprises a control circuit 19 such as a printed circuit board known as PCB for "Printed Circuit Board", supporting a set of electrical and / or electronic components. 3. The control module 17 comprises a predetermined number of terminals 20 connected to the motor 3 for supplying the windings of the motor 3. According to the nonlimiting example shown, the control module 17 comprises three terminals 20 connected to the motor. motor 3.
    The control module 17 furthermore comprises at least one electrical connector 21 intended to be connected to a vehicle beam, in particular to bring energy and / or a control signal to the control circuit 19. In this example, the connector electrical 21 is carried by the control circuit 19 extending in a direction B substantially perpendicular to the longitudinal axis A of the motor 3. The electrical connector 21 therefore extends here radially relative to the longitudinal axis A of the engine 3. According to the embodiment described, the extension direction B of the electrical connector 21 is substantially parallel to the main extension plane of the motor support IL.
    The motor-fan unit 1 further comprises a control module support 23. The control module 17 is thus arranged on this control module support 23, in other words the control circuit 19 and the electrical connector 21 are carried by this control module support 23.
    It is also possible to provide a protective cover 25 arranged above the control circuit 19, so as to cover the components carried by the control circuit 19, and fixed to the control module support 23. This protective cover 25 presents a shape complementary to the shape of the control circuit 19.
    The control module support 23 has a general shape extending along a main extension plane which is parallel to the main extension plane of the engine support 11. The axis A is therefore also substantially orthogonal to the main extension plane the control module support 23.
    The control module support 23 is advantageously aligned with the motor support 11 along the axis A orthogonal to the main extension planes of these two supports 11 and 23.
    According to the embodiment illustrated in FIGS. 1 and 2, the control module support 23 has a generally circular general shape.
    The control module support 23 has in this example an upper face 23a and an opposite lower face 23b.
    The control module support 23 further has in this example a central hole. More precisely, according to the embodiment described, the control module support 23 also serves as a bearing support for the motor 3. As can be seen more clearly in FIG. 4, the control module support 23 has for this purpose a substantially cylindrical chamber 26 extending axially along the longitudinal axis A from the lower face 23b of the control module support 23. The cylindrical chamber 26 is intended to receive an end (not visible in the figures) of the control shaft. transmission 4 of the engine 3, opposite the end of the transmission shaft 4 mounted on the fan wheel 5, and is therefore intended to serve as bearing support. The cylindrical chamber 26 is also intended to be received in the central hole of the engine support 11.
    According to the illustrated example, the motor support 11 is arranged axially between the control module support 23 and the fan wheel 5. In this case, the upper face 11a of the motor support 11 is arranged facing the control module support. 23.
    The motor-fan unit 1 may furthermore comprise a cooling means 27 of the control module 17 of the engine 3, such as a cooling radiator 27, for evacuating the heat produced by the electrical and / or electronic components carried by the circuit. order 19.
    According to the illustrated embodiment, the control module support 23 comprises such a cooling means 27 of the control module 17.
    The control module support 23 is advantageously made of aluminum.
    Furthermore, the control module 17 is mounted in this example on the upper face 23a of the control module support 23. The control module 17 can be fixed by any appropriate means to the control module support 23, for example by screwing. The lower surface 23b of the control module support 23 can itself be arranged opposite the engine support 11. The control module 17 is therefore arranged on the control module support 23 on the opposite side to the engine support 11.
    According to the illustrated embodiment, the control module support 23 is rigidly connected to the stator of the motor 3.
    In addition, the control module support 23 is assembled to the engine support 11. The control module support 23 is for example assembled to the engine support 11, by its lower face 23b facing the engine support 11. More specifically, the support control module 23 is provided to cooperate with the internal structure 13 of the motor support 11. The assembly is made along the axis A orthogonal to the main extension planes of the two supports 11 and 23, as shown schematically in FIG. The axis A is also designated by assembly axis.
    The motor support 11 and the control module support 23 are for example assembled to one another by assembly faces 11a, respectively 23b. The assembly face 11a of the engine support 11 extends along the main extension plane of the engine support 11. Similarly, the assembly face 23b of the control module support 23 extends along the plane of main extension of the control module support 23. The assembly faces 11a and 23b therefore extend in planes parallel to each other and perpendicular to the longitudinal axis A. For this purpose, the control module support 23 presents less a fixing zone for the assembly to the engine support 11. The fixing zones on the one hand of the engine support 11 and on the other hand of the control module support 23 are able to cooperate with one another to the assembly of the engine support 11 to the control module support 23, in at least two different positions of the engine support 11 relative to the control module support 23. The attachment zones of the engine support 11 and the control module support 23 his t therefore complementary.
    Of course, the fixing zone of the engine support 11 comprises mounting elements and the fixing zone of the control module support 23 comprises complementary mounting elements of the mounting elements of the attachment zone of the engine support 11.
    The motor support 11 and the control module support 23 are therefore positioned relative to one another via their attachment zones.
    More specifically, the assembly of the control module support 23 to the engine support 11 can be done in at least two different positions, preferably in three different positions. By way of example, three assembly positions between the motor support 11 and the control module support 23 are illustrated in FIGS. 5a to 5c. In each position, the electrical connector 21 extends in a direction L1, L2 or L3 distinct which is different depending on the selected assembly position between the motor support 11 and the control module support 23.
    Thus, during assembly, a first assembly carried by the control module support 23 and a second assembly formed by the engine support 11, can be rotated relative to each other to the position assembly chosen from among the three possible assembly positions in this example. According to the embodiment described, the first assembly is shown in FIG. 2, and thus comprises the control module support 23 and in particular the motor 3, the control module 17 with its control circuit 19 and the electrical connector 21, and the possible protective cover 25. The orientation of the first set relative to the second set is adjustable. The orientation of this first set is defined during assembly.
    After assembly of the assembly formed by the control module support 23 and the elements that it carries, and the motor support 11, a cover 28 (see FIG. 1) of generally circular shape can still be arranged and fixed on the motor support 11. The cover 28 is for example fixed at the level of the outer ring 15 of the motor support 11.
    Advantageously, in order to allow the assembly of the motor support 11 to the control module support 23 in different assembly positions, the zone of attachment of at least one of the supports 11 or 23 is invariant by rotation of an angle predefined around the axis A substantially orthogonal to the main extension planes of the supports 11 and 23, as shown in FIGS. 5a to 8.
    According to the illustrated embodiment, both the zone of attachment of the motor support 11 and the zone of attachment of the control module support 23 are invariant by rotation of a predefined angle a around the axis A. The angle a Rotational invariance is the same for one or other of the attachment areas. In the illustrated example, it is a rotation invariance of 120 °.
    The attachment zone of the engine support 11 comprises at least one set of mounting elements 29 visible in FIG. 6. The expression "set of mounting elements" 29 or 31 here designates at least one mounting element or several elements mounting.
    Similarly, the fixing area of the control module support 23 comprises at least one set of mounting elements 31 visible in FIGS. 7 and 8.
    In FIGS. 6 to 8, the sets of mounting elements 29, respectively 31, are delimited by dashed axes.
    Each set of mounting elements 29 or at least set of mounting elements 29 provided on the attachment area of the motor support 11 is arranged opposite a set of complementary mounting elements 31, provided on the zone of attachment of the control module support 23, in the assembled state of the motor-fan unit 1.
    Moreover, as is better seen in FIG. 7, the control module 17 is fixed on the control module support 23, and in this example in particular the control circuit 19 is fixed on the control module support 23. in a predefined position. The control circuit 19 at least partially covers the control module support 23. In this case, at least some mounting elements are arranged jointly and complementary to the control module support 23 and the control circuit 19. Sets of mounting elements 31 are therefore provided both on the control module 17, in this case in particular the control circuit 19, and on the control module support 23.
    On the other hand, referring again to FIG. 6, the motor support 11 may comprise at least two sets of mounting elements 29.
    In particular, one set of mounting elements 29 is the image of the other set of mounting elements 29 by rotation of the predefined angle α about the axis A. In particular, the term image symmetrical image. In other words, the sequence of mounting elements of a set 29 is repeated by rotation of the predefined angle a around the axis A. These two sets of mounting elements 29 may be designated by sets of elements of symmetrical mounting.
    The two sets of mounting elements 29 make it possible to assemble the motor support 11 and the control module support 23 to each other in at least two different positions according to the set of mounting elements chosen.
    Alternatively or additionally, it is the control module support 23 (see FIGS. 7 and 8) which comprises at least two sets of mounting elements 31, one of which is the image of the other by rotation of the predefined angle around the axis A.
    According to a preferred embodiment, the two supports, namely the motor support 11 on the one hand and the control module support 23 on the other hand, respectively comprise the same number of sets of mounting elements 29, 31 respectively. .
    According to the embodiment illustrated in FIGS. 6 to 8, the engine support 11 comprises three sets of mounting elements 29 and the control module support 23 also comprises three sets of mounting elements 31. Each set of elements mounting 31 of the control module support 23 is arranged vis-à-vis a set of mounting elements 29 complementary to the engine support 11 in the assembled state of the fan motor unit 1.
    According to this embodiment, the sets of mounting elements 29, respectively 31, are distributed at a constant angular offset α on the zone of attachment of the motor support 11, respectively of the control module support 23. The angular offset corresponds to the invariance angle by rotation.
    Furthermore, referring again to FIGS. 6 to 8, the sets of mounting elements 29 of the fastening zone of the engine support 11 are for example distributed at the same angular offset a as the sets of mounting elements 31 of FIG. the area of attachment of the control module support 23. Advantageously, the angular offset α is constant.
    According to the particular example illustrated, the three sets of mounting elements 29 of the motor support 11 are distributed at an angular offset α of the order of 120 °, and the three sets of mounting elements 31 of the support module module. command 23 are distributed at the same angular offset α of the order of 120 °.
    FIGS. 5a to 5c schematically illustrate the three possible assembly positions between the motor support 11 and the control module support 23 in this case.
    FIG. 5a shows a first assembly position of the motor support 11 to the control module support 23, in which the electrical connector 21 extends in a first direction L1. FIG. 5b shows a second assembly position of the motor support 11 to the control module support 23, in which the electrical connector 21 extends in a second direction L2 different from the first direction L1 and here forming a angle a of the order of 120 ° with respect to the first direction L1. Finally, in FIG. 5c, there is shown a third assembly position of the motor support 11 to the control module support 23, in which the electrical connector 21 extends in a third direction L3 different from the first direction L1 and different from the second direction L2. In addition, this third direction L3 here forms an angle α of the order of 120 ° with respect to the first direction L1 and with respect to the second direction L2.
    To switch from one configuration to another, it suffices to turn the control module support 23 and the parts that it bears relative to the engine support 11. Thus, the configuration illustrated in FIG. 5b, respectively 5c, is obtained from the same elements as the configuration illustrated in FIG. 5a, the only difference with respect to the configuration of FIG. 5a being that the control module support 23 and the parts it carries have been rotated by the order of 120 ° (FIG. 5b), respectively 240 ° (FIG. 5c) around the assembly axis A.
    Furthermore, each set of mounting elements 29 of the motor support 11 and each set of mounting elements 31 of the control module support 23 comprises at least one mounting element for the assembly or more precisely the attachment of the engine support. 11 in the control module support 23.
