    [0001] BACKGROUND OF THE INVENTION The present invention relates to the field of aerodynamics and more particularly to the field of actuators of moving members, in particular for vehicles, such as by example of the air distribution flaps in the heating, ventilation and air conditioning circuits. Such circuits are particularly present in the air conditioning installations of the vehicles. BACKGROUND OF THE INVENTION A large part of the vehicles is now equipped with air conditioning devices and whatever the type of motorization of the vehicle. Conventionally, such a device comprises a cold generating unit, driven by the vehicle engine or by a dedicated electric motor, as well as heat recovery elements of the engine of the vehicle (in the case of an internal combustion engine ) or heating elements, generally electric. A flow of air taken in the passenger compartment or outside the vehicle is directed through a heat exchanger to add or subtract calories to this flow. The air stream thus heated or cooled is then led to different points of blowing of the vehicle through a network of air distribution ducts. In order to be able to direct the flow of air, make mixtures of hot and cold air, switch from a heating circuit to a cooling circuit or regulate the flow of the air flow at each of the blowing points, shutters Aeraulics are placed at various points in the network of air distribution ducts. The position of these ventilation flaps is generally controlled using electromechanical actuators.
    [0002] Usually, such an actuator comprises an electric motor whose motor shaft is provided with a worm. This worm meshes with the first gear of a gear train transmitting, at a reduction ratio of about 20, the rotation of the motor shaft to an output component of the actuator. The output component, generally a toothed wheel, a splined shaft or any other connector capable of transmitting a rotation, interacts with a homologous component integral with an axis 10 of rotation of the ventilation flap. Such an actuator is packaged in a parallelepipedal casing resulting from the assembly of two half-housings which each comprise bearings guiding in rotation the axes of the gears of the gear train 15. The output component of the actuator protrudes from one of the faces of the housing in a direction perpendicular to that of the output shaft of the electric motor. The housing also comprises means for locking in rotation of the electric motor, often made with flat surfaces bearing on flats made on the motor casing. This requires particular machining. Such an actuator has several drawbacks in particular in terms of cost, size and ease of assembly. In addition, the housing must be provided with means for countering its rotation relative to the flap support, which is generally achieved by means of screws passing through the housing to bite into the plastic material of the flap support. OBJECT OF THE INVENTION An object of the invention is to reduce the size of the actuator and the costs associated with its manufacture and assembly.
    [0003] SUMMARY OF THE INVENTION 3030150 3 To this end, there is provided a positioning actuator of a movable member, in particular for a vehicle, comprising an electric motor (30) housed in a motor casing closed at one end by A cover, the motor comprising a motor shaft which passes through the cover, the drive shaft being rotatably connected to an epicyclic reduction gear having an outer ring gear, the cover (35) comprising locking means blocking the rotation of said cover 10 by relative to the engine casing and blocking the rotation of said outer ring gear. Thus, the rotational locking of the gearbox with respect to the motor is ensured by the cover which is an integral part of the motor casing, which facilitates the assembly of these two elements during the manufacture of the actuator and reduces them. the costs. The use of an epicyclic reduction gearbox improves the compactness of the actuator and also reduces the manufacturing costs.
    [0004] Advantageously, the locking means are arranged to also lock the motor casing in rotation with respect to the casing. This arrangement facilitates the assembly of the actuator elements together and reduces the manufacturing time and cost of the actuator. Advantageously, the motor shaft extending along a longitudinal axis, the locking means also perform a guide in position of the cover relative to the casing in a longitudinal direction. The use of the same means to realize the locking in rotation and the guiding of the cover relative to the casing also reduces the manufacturing time and cost of the actuator. According to a particular embodiment, the locking means comprise at least one element projecting from the lid in a direction perpendicular to the axis of the motor shaft. According to another embodiment, the electric motor is a stepper motor and the locking means also comprise an indexing reference of the motor for indexing the rotation of the motor relative to a point of the envelope. This allows to take advantage of the engine calibration operation during its manufacture and avoids having to perform a final calibration operation of the actuator.
    [0005] Other characteristics and advantages of the invention will emerge on reading the following description of particular non-limiting embodiments of the invention.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIGS. 1 to 7, the actuator according to FIG. the invention, generally designated 1, is mounted in a vehicle (not shown) and comprises a housing 10 enclosing an electric motor 30, for example an electric stepping motor, connected to a two-stage epicyclic reduction gearbox 50 including a component outlet 70 is rotatably connected to a movable member, for example a ventilation flap (not shown) of a motor vehicle.
    [0007] The housing 10 comprises a first half-housing 11 and a second half-housing 12 connected to each other. According to a particular embodiment, the connection is made by latching four lugs 12.1 of the second half-housing 12 in corresponding windows 11.1 made in tongues 11.2 projecting from the first half-housing 11. However, other modes of link can be used. The first half-casing 11 extends at least partially around the motor 30 while the second half-casing 12 comprises an opening 24 through which the outlet component 70 extends. The motor 30 is housed in the housing 30. A cylindrical envelope 31. According to an exemplary embodiment, this cylindrical envelope 31 is integral with the stator 32 of the motor 30. The stator 32 consists, for example, of a series of copper windings surrounding a rotor 33 which is integral with the minus a motor shaft 34 of the motor 30. The motor shaft 34 extends along a longitudinal axis X of the actuator 1 projecting from a cover 35 extending perpendicular to the longitudinal axis X and closing one end of In other words, the drive shaft passes through the cover along the longitudinal axis X of the actuator 1. According to one embodiment, a toothed wheel 36 is integral with the drive shaft 34. This toothed wheel 36 is located on the portion of the output shaft 34 located near the cover 35. According to a particular embodiment, a washer 37 of lubricant material, such as Teflon, 20 is interposed between the base of the toothed wheel 36 and the cover 35, the motor shaft 34 extending well beyond the face of the toothed wheel 36 opposite that in contact with the washer 37. As shown in Figure 2, the electric circuit 38 of the electric motor 30 is connected to at least one conductor. According to a particular embodiment, the electrical circuit 38 is connected to at least two conductors, preferably four identical conductors 39 parallel to each other.
    [0008] This or these conductors are substantially S-shaped each having at least one elbow. According to a particular embodiment, this or these conductors have at least two elbows 39.1 and 39.2. In the remainder of the description, only one of the conductors 39 will be described, the other conductors being identical.
    [0009] In the particular embodiment in which the conductor has two elbows, the elbow 39.1 connects a first end section 39.3 of the conductor 39 connected to the electrical circuit 38 to an intermediate section 39.4 which is itself connected by the elbow 39.2 to the second end section 39.5 of the driver. The first and second end sections 39.3 and 39.5 are mutually parallel and extend perpendicular to the axis X of rotation of the motor shaft 34 while being non-collinear. The second end portion 39.5 of the conductor 39 is connected to a first end of an electronic card 40. According to an exemplary embodiment, the electronic card 40 extends in a plane parallel to the X axis. The second end of the card 40 comprises at least one conductor 40.1. According to the embodiment illustrated in FIG. 3, the second end of the card 40 comprises four conductors 40.1 extending parallel to the sections 39.3 and 39.5. This or these conductors 40.1 are intended to be connected to a low current network of the vehicle 100. This or these conductors 40.1 are made using a steel wire 25. According to an exemplary embodiment, this steel wire has a square section of width 1 '. As used herein, the term "elbow" refers to a change in direction of an elongate member resulting from bending or folding, the elbow being able to have a rounded or pointed profile. The conductor 39 is made by bending a wire - for example a steel wire - whose square section has a side of length 1. Preferably, the minimum length of the sections 39.3, 39.4 and 39.5 is substantially equal to 2 mm. The 3030150 8 successive sections 39.3 and 39.4 extend in directions preferably forming an angle of 70 ° between them. The directions of the successive sections 39.4 and 39.5 also form an angle of 70 ° between them. Note that the electrical conductors 39 are sufficiently rigid so that their welding is easily automated. The elbows provide good driver compactness, flexibility to absorb the vibrations of the engine and its environment, and flexibility to accommodate larger manufacturing and mounting tolerances, thus reducing manufacturing costs. Conductors 39 also have a lower cost than that of a flexible conductor. In addition, because of the elbows 39.1, 39.2, the end sections 39.1, 39.2 are offset relative to each other. It is therefore possible to mount electronic components on one or the other face of the portion of the electronic card 40 next to the end sections 39.5 and facing the bend 39.1 and the intermediate section 39.3. As seen in FIGS. 1 to 3, the cover 35 is disk-shaped and extends in a plane perpendicular to the X axis. However, the cover may be of different shape. The cover 35 comprises at least one tongue 41 projecting radially from the disc. According to the example illustrated in FIG. 2, the cover 35 comprises a plurality of tongue 41 projecting radially from the disc and which extend in different directions, for example perpendicular to one another. Each tongue 41 cooperates with a homologous groove 42 of the casing 31. The tongue or tabs 41 have a length greater than the thickness of the casing 31 and therefore project from it, when the cover 30 is closed. The outer ring gear 51 of the first stage of the epicyclic gear train 50 has a lower face which rests on the cover 35. The ring 51 5 comprises a skirt 52 projecting axially and which surrounds the upper portion of the outer surface. of the casing 31. This skirt 52 comprises at least one notch 53 opening in which is engaged a tongue portion 41 projecting from the casing 31.
    [0010] According to a particular embodiment, the skirt 52 comprises a plurality of open slots 53 in which the portions of the tongues 41 projecting from the casing 31 engage. This assembly rotates the crown 51 in rotation. relative to the casing 31. The length of the tongue or tabs 41 is such that they have radially projecting portions of the skirt 52. The first stage of the sun gear 50 comprises one or more satellites 54.1 and 54.2 meshing with each other. on one hand with the ring gear 51 and on the other hand with the gearwheel 36 which acts as an inner sun gear. The satellites 54.1 and 54.2 are keyed respectively on shafts 55.1 and 55.2 which extend between two parallel lugs 56.1 and 56.2 of a planet carrier 56. One or more of the satellites 57.1 and 57.2 of the second stage 57 of the epicyclic reduction gear 50 are they, too, keyed respectively on the shafts 55.1 and 55.2. These satellites 57.1 and 57.2 each comprise one tooth less than the satellites 54.1 and 54.2 and mesh with an outer planetary ring gear 71 integral with the output component 70. The tab 56.1 comprises a circular opening 56.3 at its center through which 'Spread the toothed wheel 36 and the drive shaft 34. As seen in FIG. 3, the motor shaft 34 of the motor 30 extends along the axis X through a central cylinder 58 integral with the lug 56.2. This connection between the motor shaft 34 and the planet carrier 56 then carries out the rotational guidance of the planet carrier 56 around the axis X.
    [0011] The outlet component 70 comprises a protruding portion, for example in the form of a splined shaft 72 of X axis, intended to cooperate with a corrugated bore 92 homologous to the ventilation flap 90. The splined shaft 72 comprises a bore The housing 10 will now be described in greater detail with reference to FIGS. 1 to 7. According to one embodiment, the half-housing 11 comprises a cylindrical portion 13 having a closed end projecting radially from which comes a parallelepipedal portion 14. The portions 13 and 14 are flush at a plane 15 of junction with the half-housing 12. The half-housing 11 comprises a tongue 16 extending radially projecting from a face 14.1 of the parallelepipedal portion 14. A second tongue 17 located in the same plane as the face 14.1 comes into axial projection of the plane 15. This tongue 17 has an end of istale 17.1 provided with one or more triangular teeth 18 at the top of which is formed a flat 19 of width substantially equal to the length l 'of one side of the section of the conductors 40.1. The inner face of the cylindrical portion 13 of the half-casing 11 comprises one or more grooves 20 extending parallel to the X-axis and forming one or more openings. According to a particular embodiment, the inner face of the cylindrical portion 13 of the half-casing 11 comprises three grooves 20 located at 90 degrees to one another.
    [0012] 3030150 11 This or these grooves 20 open at the junction plane 15. The half-housing 12 comprises a cylindrical portion 21 projecting radially from which a tubular parallelepipedal portion 22. The portions 21 and 22 are flush with a plane 15 'of junction with the half-casing 11 and have an opening at this end. A disc 23 of greater diameter than that of the cylindrical portion 21 and provided with a central bore 24 for passing the spline shaft 72 extends transversely and closes the first cylindrical portion 21. The disc 23 also comprises a lug 25 radially projecting from the disk 23 and provided with a bore 26. A cylindrical wall 27 of axis X extends at the periphery of the disk 23 in the region which is delimited by the plane of the disc 23 which is opposite to that in which the cylindrical portion 21 extends. An elastic tab 28 projects from the outer face of the cylindrical wall 27 in a substantially tangential direction so as to create a deformable mechanical obstacle forming a rotational stop. The inner face of the wall 27 comprises one or more helical threads 27.1, 27.2 and 27.3.
    [0013] According to a particular embodiment, the inner face of the wall 27 comprises three helical threads whose overlapping portions delimit grooves 27.4, 27.5 and 27.6. Finally, as can be seen in FIGS. 5 and 7, the bottom of the parallelepipedal portion 22 comprises one or more square slots 29.1 having a side substantially equal to 1. According to a particular embodiment, the bottom of the parallelepiped portion 22 comprises four parts. square squares which are separated by three 3030150 12 triangular teeth 29.2. The parallelepipedal portion 22 also has a face provided with a cutout having one or more grooves and one or more protruding portions. This cutout is intended to receive and retain a specific electrical connector. The manufacture of the actuator 1 is described with reference to FIGS. 8.1 to 8.4. During its manufacture, the motor 30 is indexed with respect to one of the tongues 41 of the cover 35. The rotation reference of the motor 30 is then taken from this tongue 41. The conductor (s) 39 are welded to the 40. As shown in FIG. 8.1, the epicyclic reduction gear 50 is presented facing the drive shaft 34 and moved so that the drive shaft 34 engages in the central bore of the cylinder 58 and then through the bore 73 of the outlet component 70. The motor shaft extending beyond the toothed wheel constituting the inlet component engaging in the bores allows relative guidance of the epicyclic reduction gear 70 and the output component. 70 relative to the motor 30 during assembly and then reduce the assembly time. In addition, the rotation guide of the planet carrier by the output shaft of the engine advantageously reduces the difficulties and mounting time of the planet carrier and makes the guidance more reliable, thereby improving the overall reliability of the actuator. The ring 51 is then rotated until the groove (s) 53 are facing the tab (s) 41 and the epicyclic reduction gear 50 is moved in a direction parallel to the X axis so that the tab (s) 41 are engaged in the grooves 53. The epicyclic reduction gear 50 is then locked in rotation with respect to the motor 30.
    [0014] The assembly consisting of the motor 30 and the epicyclic reduction gear 50 is presented facing the half-housing 11 so that the groove or grooves 20 of the half-housing 11 face the tabs 41 of the cover 35.
    [0015] The motor unit 30 / epicyclic reduction gear 50 is then moved in a direction parallel to the axis X so that the tongue or tongues 41 are engaged in the grooves 20 (FIG. 8.2). The engagement of the tongue or tongues 41 in the grooves 20 rotates the motor 30 / epicyclic reduction gear unit 50 relative to the half-casing 11. In this position, the conductor 40 or conductors rest on the or the flats 19 of the triangular teeth 18 (FIG. 8.3) and the periphery of the electronic card are received in the groove or grooves formed in the walls of the parallelepipedal portion 14.1 of the half-casing 11. The half-casing 12 is then presented with In such a way that the splined shaft 72 faces the bore 24 and the windows 11.1 of the tongues 11.2 are aligned with the lugs 12.1. A translation along the axis X of the half-housing 12 relative to the half-housing unit 11 / motor 30 / epicyclic reduction gear 25 then brings the respective junction planes 15 and 15 'of the half-housings 11 and 12 in contact. According to a particular embodiment, lugs 12.1 snap into the windows 11.1 of the tongues 11.2 and complete the assembly of the actuator 1. When the half-housings 11 and 12 are assembled, the conductor or drivers 40.1 are received in the crenellations 29.1 and pinched between the bottom thereof and the flats 19 of the teeth 18 (Figure 5). This ensures that the conductor 40.1 3030150 14 is maintained in an effective position and reduces the mechanical stresses on the welds connecting the conductors 40.1 to the electronic card 40. The relative positioning of the conductor (s) 40.1 is guaranteed, which makes it possible to avoid to use overmolded tips. During the assembly of the elements of the actuator 1, the indexing reference of the engine is maintained. Indeed, it corresponds to one of the tongues 41 whose position relative to the housing 10 is determined. It is then not necessary to carry out a new calibration operation of the motor 30, which represents a significant advantage over the actuators of the prior art. FIG. 10 shows a connector 80 for connecting the actuator 1 to a device, for example a ventilation flap (not shown) of a ventilation system. This connector 80 comprises two coaxial cylindrical walls 81 and 82 projecting perpendicularly to a flat portion of the outer face of a hood 83 of the air flow circuit. The wall 81 surrounds a bore 84 behind which is a corrugated bore 92 (shown in dotted line in particular in Figure 11.1) integral in rotation with the axis of rotation of the air shutter. The wall 82 extends around the wall 81. One or more helical threads 85, 86 and 87 project radially from the outer face of the wall 81 and respectively have a free end portion 85.1, 86.1 and 87.1. The outer face of the cap 83 also comprises a parallelepipedal pin 87 projecting in a direction substantially perpendicular to the plane of the flat portion of the cap 83. The mounting of the actuator 1 on the connector 80 is described with reference to FIGS. 11.5.
    [0016] The actuator 1 is shown to be coaxial with the bore 84 (Fig. 11.1). In this position, the splined shaft 72 faces the splined bore 92. The actuator 1 is then moved along the X axis to insert the wall 27 of the housing 10 between the two cylindrical portions 81 and 82. The translational movement of the actuator 1 is carried out until the free end portions 85.1, 86.1 and 87.1 of the helical threads 27.1, 27.2 and 27.3 of the housing 10 of the actuator 1 come into contact with the threads 10 helical 85, 86 and 87 of the connector 80 (Figure 11.2). The actuator 1 is then rotated about the X axis clockwise so as to engage the helical threads 27.1, 27.2 and 27.3 with the homologous threads 85, 86 and 87.
    [0017] During this rotational movement of the actuator 1, the free end 28.1 of the elastic tab 28 comes into contact with the lug 88. This situation is shown in FIG. 11.3 and corresponds to a rotation of the actuator 1 relative to the lug 88 20 of approximately 15 to 30 ° clockwise. Further rotation of the actuator 1 relative to the connector 80 causes deformation of the elastic lug 28 against the lug 88. This rotational movement is continued until the free end portions 85.1, 86.1 and 85.1. 87.1 are engaged respectively in grooves 27.4, 27.5 and 27.6 (Figure 11.4). This corresponds to a maximum rotation of about 30 ° of the actuator 1 about the X axis in the clockwise direction. In this relative position of the actuator 1 and the connector 80, the elastic tab 28 returns to its position and the free end 28.1 bears behind the lug 88, thus blocking the rotation of the actuator 1 relative to the connector 80 The actuator 1 is then locked in position on the connector 80 and the splined shaft 72 of the actuator 1 is engaged in the grooved bore 3030150 16 of the ventilation flap. The electrical connection of the actuator 1 to the low-voltage network of the vehicle is achieved by engagement of a connection pin on the conductor or conductors 40.1.
    [0018] Removal of the actuator 1, after electrical disconnection, is done by exerting a pressure in a substantially radial direction on the end 28.1 of the elastic tab 28 to disengage it from the pin 88. Then simply to impose a rotational movement of 60 ° counterclockwise to the actuator 1 in order to disengage it. In case of accidental breaking of the elastic tab 28 or the lug 88, it is possible, during the reassembly of the actuator 1, to immobilize the actuator 1 in rotation relative to the cover 83 by engaging a self-tapping screw in the hole 26 of the ear 25. This screw will become caught in the material constituting the cover 83. The actuator 1 can thus be easily mounted and disassembled without requiring tools. The indexing of the motor 20 being made with reference to a point of the housing 10 of the actuator 1, and the final position thereof with respect to the ventilation flap 90 being known, no additional calibration operation is required. It will be noted that the rotational locking of the gearbox 25 with respect to the motor is ensured by the cover which is an integral part of the motor casing, which facilitates the assembly of these two elements during the manufacture of the actuator and reduces costs. The use of an epicyclic reduction gearbox improves the compactness of the actuator and also reduces its manufacturing costs. Of course, the invention is not limited to the embodiment described but encompasses any variant within the scope of the invention as defined by the claims.
