    [0001] Field of the invention The present invention relates to a motor-driver module comprising an electric motor and a geared motor housing with an electronic interface receiving an electronic module inserted in the electronic interface in the direction of insertion, the electronic interface having walls spaced from one another, and which, in combination with the inserted electronic module, form a closed electronic box for the electronic circuit. The invention also relates to a method of realizing a geared motor module. State of the art There are already known different drive devices comprising a separate electronic module coupled to the housing of the drive device. Document DE 200 04 338 A 1 describes, for example, a drive device comprising an electric motor housed in a transmission housing in which an insertable module is slid. The module has a front surface with a connector on the outside and a circuit board on the inside, receiving electronic components and motor contacts for power supply. A finger of the circuit board has a Hall sensor as surface mounted component (SMD component) which cooperates with an annular magnet carried by the armature shaft. According to EP1618645B1 discloses a drive unit whose outer side wall has latching holes for an electronic interface. The hooks of the electronic module penetrate into its attachment holes when the electronic module is inserted completely. The disadvantage of this device is that the hooking connection of the electronic interface can be detached at any time in a non-destructive way to open the electronic box. This makes it possible to intervene on the electronic unit and install it again in the interface without this intervention leaving any traces. OBJECT OF THE INVENTION The present invention aims to develop a geared motor module to prevent unauthorized intervention on the module and including any non-destructive intervention. DESCRIPTION AND ADVANTAGES OF THE INVENTION For this purpose, the subject of the present invention is a geared motor module comprising an electric motor and a geared motor housing with an electronic interface receiving an electronic module inserted in the electronic interface in the direction of insertion and the electronic interface comprises walls spaced apart from each other, which, in combination with the inserted electronic module, form a closed electronic box for the electronic circuit, the electronic interface comprises fastening elements and the electronic module comprises corresponding complementary latching elements, which after complete insertion of the electronic module are hung integrally with each other and are completely in the electronic box. The gearmotor module according to the invention as well as its manufacturing method have the advantage that the connection by hooking in the electronic box does not make it possible to detach the electronic module in a non-destructive manner with respect to the electronic interface. picnic. When the electronic module is slid into the electronic interface, these two elements are connected in solidarity and we can check if the electronics is still in its original state of manufacture and has not been handled in a way not authorized. The housing portions of the electronic module and that of the electronic interface constitute a generally closed housing for the electronic circuit. According to a particularly economical and reliable feature, the hooking elements are hooks that snap into latching eyelets or matching latches.
    [0002] The hooks can be provided on the electronic interface or on the electronic module. The corresponding complementary coupling elements are provided on the corresponding housing part. This solution has the advantage of not requiring a link segment or additional security, which allows a saving of components and mounting time.
    [0003] So that the hooks hook securely in the corresponding complementary hooking elements, they are carried by elastic branches connecting them to the housing parts.
    [0004] In a particularly advantageous manner, these movable branches extend in the direction of insertion so that when the electronic module is mounted, they are automatically discarded and when the insertion end stop is reached, the elements 'hooking back safely in the complementary fastening elements. As the fastening elements and the complementary fastening elements are made in one piece with the electronic interface and the electronic module, there is no additional cost for the manufacture and mounting. The embodiment as an injected piece of plastic material makes it possible to have elastic fastening elements thanks to their geometry. According to a preferred development, the housing part of the geared motor module comprises inside the electronic interface, a recess oriented radially with respect to the armature shaft and through which one can slide the circuit board of a module insertable. The circuit board may be tangential or radial with respect to the armature shaft, for example also for a larger dimension, in the axial direction or in a plane perpendicular to the armature shaft. This makes it possible to position sensor elements in the immediate vicinity of the armature shaft or on a generator element carried by the armature shaft. If the insertion module has a circuit board that slides into a recess of the gearmotor module housing, the arrangement of the sensor system for entering the speed of rotation can be done in a simple manner with an exact position capture of the actuator. We will thus have a precise positioning of the sensor system for example in the case of two Hall sensors, thanks to the side walls and the guide rail of the electronic interface. If the sealing surfaces of the electronic interface are realized so that with the joints of the insertable module they provide the radial seal with respect to the direction of insertion, the sealing effect is ensured independently of the applied pressure in the insertion direction. Particularly advantageously, along the edge of the opening of the electronic interface, in the direction of insertion, guide rails are made for the electronic module making it possible to press the radial seal against the sealing surface formed by the inner wall of the electronic interface. This prevents the relatively flexible walls of the electronic interface from moving apart laterally when the module is inserted and thus the interface is no longer sealed. At the same time, the axial, folded, formed extensions stabilize the walls of the electronic interface and also serve for the mechanical fixing of the electronic module even in the case of a module having no seal.
    [0005] According to a preferred development, the hooking connection outside the interior volume receiving the sealed electronics is nevertheless located inside the electronic housing formed by the outer walls of the housing. It is advantageous in that the front face of a surface of the electronic module comprises a seal which is applied against a corresponding sealing surface of the electronic interface and away from this surface, there is a bottom surface for a connector skirt forming a surrounded cavity. This cavity offers sufficient space to fix the fastening elements and the corresponding complementary fastening elements. The cavity is closed laterally in the direction of insertion by the other walls of the housing or the guides / guide rails which interpenetrate. In a particularly compact and reliable manner, the attachment elements and the complementary fastening elements are in the same plane transverse to the rotor shaft in which are also the guide rails and the guides. Thus the attachment link is in the region stabilized mechanically by the guides and guide rails so that during insertion, the hooks hook securely into the latching beaks.
    [0006] To have additional security, control ports are made in the electronics box to check that the fastening elements have hooked securely into the complementary fastening elements. These control orifices are particularly economical if they are through orifices made in the area of the guides or guide rails so that one will be directly seen on the attachment element and / or the complementary fastening element. The control holes are dimensioned to not allow to intervene and manipulate or detach the attachment link. According to a preferred development, the inspection orifices are located in the region of the guide rails of the electronic interface. For this, we can for example use an area of the folded extension which is not surrounded by the corresponding groove of the electronic module. The geometry of the bonding connection is such that one can not manipulate the bonding connection by simply inserting a measuring pin. If the side walls of the electronic interface are oriented in a slightly conical shape radially relative to the rotor shaft (at a small angle, less than 5 °) the electronic module, in particular with a seal formed on the module can be introduced more easily into the electronic interface, because it is only in the last part of the insertion stroke that there will be a stronger friction between the seal and the sealing surface. Similarly, the sealing zone, during insertion, may be pressed as an axial seal against the housing wall facing the pole pot, this sealing zone being bent. The two branches preferably form an angle between 170 ° and 178 °. Thus, the necessary insertion force increases directly before the abutment, continuously, which allows to have a defined axial tightness.
    [0007] If the two surfaces whose front faces are provided with the peripheral radial joints of the electronic module make an angle of between approximately 92 ° and 115 °, then during the assembly it will suffice to have a significantly reduced insertion force exerted in the direction of insertion. because the radial seal will be compressed radially only just before reaching the final position of the electronic module, and this carefully against the corresponding sealing surfaces. To stabilize the insertion module, a frame member may be provided between the outer walls of the insertion module so that the connector pins and the circuit board can be brought into easy contact by the compression technique. This makes it possible to have the advantageous electrical contacts directly on the frame element because in the inserted state, it is completely received by the electronic interface. In this case, the circuit board can be mounted laterally without difficulty in a simple manner on the connector and guided in the insert module. The frame which supports the two ends of the branches of the surfaces forming an angle between them, advantageously comprises different bearing surfaces through which the insertable module is applied in the final mounting position against the corresponding complementary surfaces of the electronic interface. . To facilitate automatic mounting, these bearing surfaces form insertion cones so that the insertable module automatically and more easily finds its exact position. These bearing surfaces can be made both with respect to the axial direction and with respect to the direction of insertion. The cavity between the second surface with the peripheral seal and the bottom surface of the connector skirt is preferably wedge-shaped because the second surface is at an angle to the first surface and this angle is greater than 90 ° (it is preferably between 92 ° and 115 °). Thus, the wedge-shaped cavity formed by this angle can be used at the same time to receive the fastening elements and the complementary fastening elements. The bottom surface of the connector skirt forms the outer wall of the electronics housing which surrounds the wedge-shaped cavity with the corresponding wall portions of the interface walls spaced from each other. The bottom surface thus extends substantially perpendicular to the connector skirt around its outer periphery and it is formed in the connector skirt in the form of a base receiving the connector pins.
    [0008] This pedestal extends from the inner side of the connector skirt in the axial direction through the second surface through a radial seal so that the pedestal forms the passage of the connector pins to the circuit board. In the axial cavity, between the bottom surface and the second surface, the base comprises the complementary coupling elements of the electronic module which, during insertion into the electronic interface clings to the fastening elements. Thanks to the base to form the hooks, any additional axial space is useless. The base can further advantageously comprise abutment surfaces which, after complete insertion, are applied against complementary surfaces of the electronic interface or directly against the fastening elements. According to the method of the invention, the electronic module is inserted by a single operation in the electronic interface and at the same time it is hooked by a non-visible hooking of the outside. This is why the electronic box includes a control port for controlling, for example by sight or using a measuring pin that the bonding connection is correct. The geometry of the control port and the snap connection ensures that the snap connection can not be manipulated through the control port.

    [0009] DESCRIPTION OF EMBODIMENTS FIGS. 1 and 2 show a geared motor unit 10 (also called simply a geared motor) before and after the insertion of an electronic module 34; this geared motor module is particularly intended for an ice lifter. The rotor shaft 16 protrudes from the pole housing 14 of the electric motor 12 and enters the geared motor housing 18. The rotor shaft 16 carries a screw 20 in engagement with a screw wheel 22 to transmit the torque through a drive pinion 26 carried by the shaft 24, to a mechanism window not detailed. To grasp the position of a moving part, the rotor shaft 16 comprises, at the level of the geared motor housing 18, for example an annular magnet 28 cooperating with Hall sensors 30 installed on a circuit board 32 of the electronic module 34. To insert the electronic module 34, the geared motor module 10 has an electronic interface 36 made in one piece with the housing 18 by an injection method. The electronic interface 36 has walls 38 spaced from one another and which extend from the rotor shaft 16. The two walls 38 form substantially the housing 40 of the electronic circuit 33 with a radial opening 42 and an axial opening 44 with respect to the rotor shaft 16; the openings 42, 44 are connected to one another and form almost a common opening in two directions of opening (radial direction and axial direction). The two walls 38 which, in a first approximation, are parallel to each other and to the rotor shaft 16, are connected to one another by another connecting wall 39. The latter is substantially perpendicular to the walls 38 and to the rotor shaft 16. The geared motor housing 18 has a recess 46 in the direction of the rotor shaft 16 which receives the circuit board 32 inserted radially or tangentially with respect to the rotor shaft 16. For this purpose, the electronic interface 36 comprises positioning elements 31 (for example rails) for the circuit board 32. If the recess 46 is an open passage towards the inside of the motor, at the same time as the module is inserted In the direction of insertion 51 the watertightness of the entire internal volume of the gearmotor must be achieved to enable the gearmotor 10 to be used in a humid atmosphere. For this, the electronic interface 36 comprises different sealing surfaces 50 cooperating with corresponding seal segments 60 of the electronic module 34. When inserting the electronic module 34, the contact connectors 91 connected to the circuit board 32 are electrically connected by the motor contacts 95 to the brushes not shown of the electric motor 12. The guide rails 54 are formed on the electronic interface 36 in a plane 52 transverse to the rotor shaft 16; the corresponding guides 56 of the electronic module 34 slide on the guide rails 54. The guide rails 54 are in the form of a folded extension 55 of the lower axial edge of the walls 38. The electronic module 34 comprises correspondingly, a guide 56 made in the form of a groove 57 into which the folded extension 55 extends in an axial orientation. When inserting the electronic module 34 in the insertion direction 51 along the guide rails 54; the electronic module 34 encounters a stop 62 the electronic interface 36 when the electronic module 34 reaches its radial end position. The electronic module 34 is in the form of an injected piece of plastic material having a first surface 66 and a second surface 67 closing the two openings 42, 44 of the electronic interface 36 and thus forming the electronic box 40. The first surface 66 forms the outer radial wall 104 and the second surface 67 closes the electronic circuit 33 in the axial direction 49. In the area of the second surface 67, a peripheral connector skirt 64 surrounds the connector pins 67 which are located inside ; the connector pins 65 touch the circuit board 32 through the second surface 67, for example by pressed contacts 31 or welds. Between the connector skirt 64 and the second surface 67 are formed the guides 56 which lie in the plane 52. The peripheral end faces 68 of the first and the second surface 66, 67 carry seal segments 60, in particular made by injection and which constitute the radial seal for the insertion direction 51. The joint segments 60 are continuous, without interruption; the joint area 61 constitutes an axial seal pressed against another housing wall 37 in the insertion direction 51; this wall is turned towards the pole housing 14. The seal segments 60 of the electronic module 34 are pressed against the sealing surfaces 50 of the electronic interface 36, radially with respect to the insertion direction 51 at the time of insertion. . The walls 38 are substantially rectangular so that the sealed interior volume of the electronic housing 40 thus obtained is substantially a cube. The guides 56 and the guide rails 54 are substantially perpendicular to the rotor shaft 16. In order to connect the electronic module 34 in a solid manner, the electronic interface 36 comprises attachment elements 76 which penetrate into complementary hooking elements 74 of the electronic module 34. The hooking elements 76 are made in the form of hooks 78 connected by a connection by the shape to the electronic interface 36 by means of elastic branches 80 located in the plane 52. In Figure 2, the branches 80 extend in the two spaced walls 38, substantially parallel to the walls 38 for example, the legs 80 are formed on the wall 37 of the housing of the electronic interface 36, which wall is turned to the pole housing 14. When inserting the electronic module 34, the connector skirt 64 is oriented in the axial direction 49; the gripping elements 76 and the complementary gripping elements 74 are between the connector skirt 64 and the second surface 67 substantially in the plane 52 transverse to the rotor shaft 16. FIGS. 3a-3c show a section of the module in the plane 52 of the latching elements and the complementary latching elements 76, 74 which are here outside the internal electronic volume sealed by the joint segments 60 as it appears in FIG. 2 Figure 3a shows the electronic module 34 in the electronic interface 36; the cutting plane passes through a base 63 serving to pass to the connector pins 65 towards the inside of the box. The base 63 integrally carries connector pins, in particular pins forcibly inserted or integrated by injection. In the insertion direction 51, the side of the pedestal 63 facing the fastening elements 76 has complementary fastening elements 74 formed as latching noses 75. The maximum extension 70 of the two fastening elements 74, transversely to the insertion direction 51, is greater than the internal distance 72 between the two attachment elements 76, transversely to the insertion direction 51. Note also that the guide 56 has already been slipped very widely on the guide rail 54. If we continue to push the electronic module 34 of Figure 3b, further in the direction of insertion 51 between the guide rails 77 of the attachment elements 76, these shackles 76 deviate transversely to the insertion direction 51; the elastic branches 80 are then deflected for example by an angle of the order of 10 ° relative to the walls 38. Figure 3c shows the electronic module 34 in its fully inserted state; the fastening elements 76 are returned elastically after being completely passed over the complementary fastening elements 74 by the insertion ramp 77 between the fastening elements 76. The electronic module 34 has a stop surface 82 which is based on against the free ends of the fastening elements 76 in the direction of insertion 51. The end of the guide rail 54 of the electronic interface 36 has another stop 62 with respect to the direction of insertion 51. The electronic module 34 is thus positioned exactly so that the seal segments 60, in particular the axial seal of the sealing zone 61 will apply optimally against the sealing surfaces 50, 37, 39. In the fully inserted state, the walls 38 surround the housing wall 37 and the first surface 66 of the snap connection 73, in the plane 52, transversely to the rotor shaft 16. The bottom wall 89 of the connector skirt 64 with the guides 54 formed on the skirt close the connection by hooking 73 in the axial direction 49. According to an alternative embodiment of the electronic module 34 according to Figure 4, the hooks 75 are made asymmetrically relative to the base 63, transversely to the insertion direction 51. The stop 82 is formed in this case by the extension 85 in the insertion direction 51; this abutment leans directly against the housing wall 37 of the electronic interface 36.
    [0010] In this embodiment, the walls 38 comprise control orifices 86 which make it possible to look transversely to the direction of insertion 51 of all the gripping elements 76 without having to open the fastening elements 76 through the orifices of FIG. control 86. The control orifices 86 are made in the area of the guide rails 54 or their extension towards the polar housing 14 in the plane 52 as a passage; their dimension corresponds substantially to the extension of the insertion ramps 77. It can be verified, for example, that the attachment connection 73 has been correctly made, for example by a measurement of depth or by the movement of the spring through the control orifices. 86 to the latching elements 76. FIG. 5 shows another embodiment of an electronic module whose first and second surfaces 66, 67 form between them an angle 87 of between 92 ° and 115 ° and which is particularly equal to about 95 °. The joint segments 60 of the end faces 68 of the two surfaces 66, 67 are substantially the same pattern under the same angle 87. Thus, when the electronic module 34 is inserted into the electronic interface 36, this ensures that the force of Full radial application is generated by the seal segments 60 only when entering the total insertion position, which greatly simplifies the mounting process and makes it safer. As in FIG. 5, the circuit board 32 is not yet installed, a frame 88 appears which supports the two surfaces 66, 67 with respect to each other. The base 63 with the connector pins 65 it comprises, extends in the axial direction 49 of the inner side of the second surface 67 as a passage to the connector skirt 64. It appears that the bottom surface 89 of the connector skirt 64 which also includes the guides 56 form with the second surface 67 a corner cavity 90; the gripping elements 76 and the complementary fastening elements 74 are in this cavity.
    [0011] In this embodiment, the second surface 67, after insertion into the electronic interface 36 forms another wall of the electronics housing 40 and the bottom surface 89 of the connector skirt 64 forms an outer wall of the electronics housing 40. Thus, the hooking connection 73 is outside the internal volume of the housing of the electronic circuit 33, the sealing of which is effected by the seal segments 60. According to an embodiment variant, not shown, the connection with the elements 73 and the complementary latching elements 74 are also located in the sealed interior volume of the electronics box 40. FIG. 5 shows the guides 56 and the complementary latching elements 74 in the plane 52 transverse to FIG. 16. The frame 88 has in the receiving region 97, in the direction of insertion 51, towards the opening 46 of the geared motor housing 1 8, the contact connectors 91 which provide the electrical connection between the circuit board 32 and the motor contacts 95 with the carbon brushes not detailed. To correctly position the electronic module 34 in the electronic interface 36, the frame 88 has a plurality of bearing surfaces 92 which, when fully inserted, come against the electronic interface 36. The electronic module 34 is thus positioned exactly at the times in the insertion direction 51, radially with respect to the rotor shaft 16 and also in the axial direction 49 with respect to the geared motor housing 18.
    [0012] Optionally, the bearing surfaces 92 may also have an insertion cone 93, which simplifies the automatic mounting of the electronic module 34 by a robot. Figure 6a is a top view of the object of Figure 5, showing the seal segments 60 made on the second surface 67 making a small angle 94 between 1 ° and 5 ° and in particular equal to 3 °. Since these seal segments 60 are introduced in the insertion direction 51 between the spaced apart walls 38 which also make a small angle 94 between them, this considerably reduces the insertion force required for mounting. On the right, the figure again shows the abutment surface 92 with an insertion cone 93 formed on the frame 88.
    [0013] This bearing surface 92 is made on the receiving zone 97 for the connector 91. The frame 88 further comprises receiving pins 96 for the circuit board 32 not shown. Figure 6b is a view of Figure 5 from the left side with the seal segments 60 on the end faces 68 of the first surface 66. In the axial direction 49, in the opposite region of the connector skirt 64, the joint segments 60 have a folded area 59 whose two legs 58 form between them an angle 98 between 170 ° and 180 ° and preferably equal to about 174 °. The folded area 59 after insertion in the axial direction 49 is applied against the connecting wall 39 of the electronic interface 36 which is also folded by a corresponding angle 98. This increases the sealing effect in the axial direction 49. Fig. 7a shows another embodiment for Fig. 6b (the view is turned 90 °). In this view, the electronic module 34 is inserted into the electronic interface 36. The spaced apart walls 38 are oriented axially in the direction of the connector skirt 64, each with a guide rail 54 in the form of an extension. folded 55. These folded extensions 55 penetrate into the corresponding guides 56 of the electronic module 34 made here as groove 57. To facilitate the insertion of the electronic module 34, in the region of the radial opening 42, the guide rails 54, the electronic interface 36 have insertion leaves 100 which slide on the guides 56 which have optional complementary insertion leaves 102. The complementary insertion leaves 102 are made on the side of the electronic module 34 turned in the insertion direction 51 of the electronic interface 36. Between the front face 68 of the first surface 66 and the sealing surfaces 50 of the two walls 38, there are the segments of e seal 60 made here transversely to the insertion direction 51 in the form of a radial seal. The wedge-shaped cavity 90 here has a partition 111 in the insertion direction 51 forming a plug hole 110, open in the insertion direction 51 for a mounting robot which can insert the electronic module 34 in a manner fully automatic in the radial opening 42 of the electronic interface 36.
    [0014] Figure 7b is an enlarged view of the electronic interface 36 of the embodiment of Figure 7a; the electronic interface 36 is rotated 180 ° in this figure. The side of the spaced apart walls 38 opposite the axial direction 49 is provided with guide rails 54 which here occupy only substantially half of the extension of the electronic interface 36 in the insertion direction 51. The end of the guide rails 54 has on both sides control holes 86; once the electronic module 34 has been completely inserted, the control orifices are opposite the fastening elements 76, as also shown in FIG. 4. The detailed view shows, in correspondence with FIG. 7a, the insertion fillets 100 made on the folded extension 55 of the walls 38. The folded extension 55 is almost folded twice by 90 ° so that there will be walls substantially parallel to the spaced walls 38. The insertion leave is formed on the ridges in the region of the guide rails 54 where the module 34 is slid in the insertion direction 51. In this case also, the guide rails 54 and the control orifices 86 are in the plane 52 transverse to the rotor shaft 16. The device according to the invention is not limited to the insertable module 34 described above and to the electronic interface 36, but also comprises embodiments with different electronic boxes 40. s and sealing geometries 60 as well as circuit boards 32 of different shape. The heart of the invention lies in the attachment connection 73 housed inaccessibly in the control unit 40; the hooking elements 76 and the complementary hooking elements 74 have a shape and an arrangement inside the control unit 40 that can be modified. The electronic interface 36 according to the invention is intended both for application in a humid atmosphere or in a dry atmosphere. A preferred application is the actuation of moving components of vehicles, for example closing parts fitted to the openings of a vehicle, such as window lifts or sliding roofs.
