[0042] DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS
[0043] Identical, similar or equivalent parts of the different figures bear the same numerical references so as to facilitate the passage from one figure to another. Figure 1 represents a geared motor 1 for a cooling system for a motor vehicle, typically an automobile.

The engine control and command member 12 is configured to control the position of the electric motor based on the data collected by the position detector 5. Additionally or alternatively, the engine control and command member 12 is configured to transmit this data to the control unit (not shown) of the vehicle.
[0049] With joint reference to Figures 2 to 6, the reducer 3 comprises a first stepped gear 32, a second stepped gear 34, a third stepped gear 36 and an output gear 38. In each embodiment shown, the set of reduction gears 3 consists of the train of stepped gears 32, 34, 36 and an output gear 38. The reducer 3 also comprises an input axis 41, a central axis 43 and an intermediate axis 45 around which the stepped gears 32, 34, 36 and the output gear 38 are located.
[0050] The reducer 3 is configured to reduce the rotational speed at the output of the reducer 3 relative to that at the output of the electric motor 2 and to increase the torque at the output of the reducer 3 relative to that at the output of the electric motor 2.

[0052] Each of the stepped gears 32, 34, 36 comprises a cogwheel and a pinion which are coaxial which are superimposed and integral with each other in rotation. More precisely, each of the stepped gears 32, 34, 36 is in one piece in each embodiment shown. The pinion of each stepped gear 32, 34, 36 mechanically engages the cogwheel of one of the stepped gears of the stepped gear train or of the output gear 38. The first stepped gear 32 is rotated about the longitudinal direction X2-X2 of the input axis 40 by the electric motor 2. The first stepped gear 32 rotates the second stepped gear 34.

The output gear 38 comprises a coupling portion which is configured to mechanically engage by form cooperation a coupling portion at the output of the reducer 3.
[0056] The axes of the stepped gears 41, 43, 45 are parallel in pairs. The axes of the stepped gears 41, 43, 45 are also parallel to the motor axis 20. The input axis 40 serves to center the first stepped gear 32 of the reducer. The central axis 43 serves to center the second stepped gear 34 and the output gear 38. The intermediate axis 45 serves to center the third stepped gear 36.
[0057] With reference to Figures 1 to 6, the position detector 5 comprises a fixed part 51 and a mobile source. The position detector 5 is configured to detect the angular position of the electric motor 2 of the geared motor 1 and / or of at least a part of the reducer 3. In the first embodiment shown, the position detector 5 comprises a magnetosensitive probe, for example a Hall effect sensor 56.
[0058] In each embodiment shown, the position detector 5 detects the angular position of the output gear 38. The motor electronic board 12 determines the angular position of the electric motor 2 and the angular speed of the electric motor 2 from the detected angular position of the output gear 38, to control the electric motor 2. In each embodiment shown, the fixed position detector part 51 consists of a position detector electronic board 52. The position detector electronic board 52 is notably formed of a printed circuit and a Hall effect sensor 56 which is assembled to the printed circuit. The fixed position detector part 51 is in a housing 65 of the console, when it is connected to the motor electronic board 12.
[0059] The fixed part 51 of the position detector forms a detection cell of the position detector. The fixed part 51 of the position detector forms in particular a power control member of the position detector and a connection and data exchange member of the position detector.
[0060] In each embodiment shown, the moving source is a moving magnetic source, for example a permanent magnet, which is attached to the output gear 38. The moving source is intended to be detected by the fixed position detector portion 51 when it comes into contact with the Hall effect sensor 56.
[0061] The connection member of the position detector comprises terminals 8, for example three terminals for the power supply, the ground and the signal of the position detector 5.

[0063] In the two embodiments shown, the first connection portion 81 is a lower connection portion of the terminal, the intermediate portion 83 is substantially horizontal, and the second connection portion 85 is an upper connection portion of the terminal. The lower connection portion 81 of the terminal mechanically engages connection recesses 55 of the position detector electronic card 52. The upper connection portion 85 of the terminal mechanically engages connection recesses of the motor electronic card 12.
[0064] With joint reference to figures 2 to 7, the console 6 comprises a base 60, feet 62, a first plate 66, the housing 65 of the fixed part 51 of the detector, a retaining hook 70, a first slide 71 and a second slide 73 of the electronic card 52 of the detector, a groove 92 for holding each terminal 8 of the connection member, and a through conduit 90 for each terminal 8. The console 6 is a single piece in each of the embodiments shown.
[0065] The console 6 is a console for supporting and centering the central axis 43. It serves to transmit mechanical forces to the housing 10, in particular on the central axis 43 those which would tend to bend the central axis 43, and to limit the vibrations of the reducer 3. The console 6 is configured to house the fixed part 51 of the position detector. The console 6 is configured to house at least partially each terminal 8 for connecting the position detector 5 to the control and command member 12 of the electric motor. In each embodiment shown, the console 6 comprises three feet 62. The feet 62 are preferably equidistant two by two. The feet 62 each extend from the base 60 to the housing and the feet 62 carry the base 60 relative to the housing 10 and the cover 14. The console 6 is fixed to the housing 10 and / or the cover 14, for example at the feet 62.
[0066] The base 60 carries the first plate 66. The base 60 includes a second plate 64. The base 60 at least partially delimits the housing 65 of the fixed part 51 of the detector. The base 60 serves as a support and centering device for the second stepped gear 34 and the third stepped gear 36.
[0067] The upper surface SI and the lower surface S3 of the base are substantially planar and perpendicular to the longitudinal axis X3-X3 of the central axis 43. The upper surface SI and the lower surface S3 of the base form the flat surfaces of the base 60. The base 60 also comprises a lateral surface S5 which radially delimits the base radially relative to the central axis 43. The lateral surface S5 is an edge surface of the base 60.
[0068] The first plate 66 is crossed by a central orifice through which the central axis 43 extends. The first plate 66 is located axially between the second stepped gear 34 and the output gear 38 relative to the central axis 43. The first plate 66 is a support plate for the output gear 38.
[0069] The second plate 64 delimits the lower surface S3 of the base 60. It is located axially relative to the central axis 43 between the second stepped gear 34 and the third stepped gear 36. The second plate 64 comprises an intermediate orifice in which the intermediate axis 45 is inserted. The second plate 64 is a support for the third stepped gear 36.
[0070] The fixed part 51 of the position detector 5 is flush with the lateral edge surface S5 of the console 6, when the console 6 houses the fixed part 51 of the position detector.
[0071] With reference to each embodiment shown, the fixed part 51 of the position detector 5 is flush with the lower surface S3 of the base 60 outside the housing 65, when the console 6 houses the fixed part 51 of the position detector.
[0072] The first slide 71 and the second slide 73 extend from the base 60 towards the output gear 38. They are parallel to each other. They are configured to slide the fixed position detector portion 51 relative to the console 6, by mechanically engaging the lateral edges of the position detector electronic card 52.
[0073] The retaining hook 70 is oriented radially relative to the base 60. It is configured to mechanically engage a notch-shaped recess 53 of the position detector electronic card 52. The hook 70 is configured to radially retain the position detector electronic card 52 relative to the longitudinal axis X3-X3 of the central axis 43.
[0074] The slides 71, 73 and the retaining hook 70 together form a retaining member which is configured to retain the fixed part 51 of the detector in its housing.
[0075] 65. The outer surface of the console 6 has as many holding grooves 92 as there are lugs 8. Each holding groove 92 extends horizontally over a first portion 92a which houses the intermediate portion 83 of the corresponding lug 8. The first portion 92a is located on the upper surface SI of the base.
[0076] In the first embodiment shown, the first portion 92a extends over the entire length of the intermediate portion 83 of the terminal. Each holding groove 92 extends vertically over a second portion 92b which houses the upper connection portion 81 of the corresponding terminal 8. The second portion 92b extends over a foot 62 of the console, being in particular parallel to the longitudinal axis X3-X3 of the central axis.
[0077] In each embodiment shown, the console 6 is crossed by through conduits 90 which each extend from the upper surface S1 of the base to the lower surface S3 of the base, opposite the connection recesses 55 when the fixed part 51 of the detector is in the housing 65. The through conduits 90 house the lower connection portions 81.
[0078] The holding grooves 92 and the through conduits 90 together form a holding member which is configured to hold the lugs 8 relative to the console 6.
[0079] The geared motor 1 according to the second embodiment is mainly distinguished from the geared motor 1 according to the first embodiment in that it comprises a cover
[0080] 84 which at least partially covers the intermediate portion 83 of each terminal 8. In the second embodiment shown, the upper connection portion
[0081] 85 of each terminal is not held by the console 6, by not being assembled directly to the console 6. The cover 84 covers in particular the intermediate portion 83 of each terminal 8 which is located outside the console 6.
[0082] With reference to Figure 8, the method 100 for electrically and mechanically connecting the position detector 5 to the geared motor 1 comprises a step 101 of inserting the fixed part 51 of the position detector into its housing 65, by sliding it in the slides 71, 73. Following the step 101 of inserting the fixed part 51 of the position detector, the retaining hook 70 mechanically engages the fixed part 51 of the position detector.
[0083] The connection method 100 comprises a step 103 of assembling each terminal 8 to the console 6, by inserting the terminals 8 into the holding grooves 92 and into the through conduits 90. The connection method 100 comprises the connection 105 of the terminals 8 to the fixed part 51 of the detector, by inserting the lower connection portions 85 into the connection recesses 55 of the electronic card 52 of the detector. The connection method 100 comprises the connection 107 of the terminals 8 to the electronic card 12 of the motor, by inserting the upper connection portions 81 into the connection recesses of the electronic card 12 of the motor.
[0084] The connection method 100 ends with the closing 109 of the cover 14, assembling it in a sealed manner to the housing 10.
[0085] Other aspects of a console according to the invention will be presented in connection with Figures 9A - 9D. These aspects can be combined with one or other of the embodiments presented in this application in connection with Figures 1-8.
[0086] First of all, as already explained above, the outer surface of the console 6 preferably comprises grooves 92 for holding the terminal(s) 8. Various variants make it possible to improve the passage of tools for holding and / or removing the terminals and / or the positioning of the terminals: a) first of all, in the embodiment presented above, the first portion 92a extends over the entire length of the intermediate portion 83 of the terminal. As a variant (FIG. 9A), the first portion 92a' does not extend over the entire length of the intermediate portion 83 of the terminal, but over a fraction thereof, for example between 20% and 60% thereof.The longitudinal extension of the bosses 192'a for guiding the terminals is therefore limited in the same way, which makes it possible to facilitate the passage of tools for holding the terminals when inserting the terminals into the console; b) and / or a clearance (or opening) 194 can be added to a portion of the extension of the terminals and of the first portion 92a': this facilitates the demolding of the part (it allows the passage of the part of the mold which forms the two slides) and possibly the passage of the tools for removing the terminals; as can be seen in figures 1, 2 and 9A, this clearance is elongated in an inclined direction (but not perpendicularly), in a plane perpendicular to the longitudinal axis X3-X3 of the central axis 43, relative to the direction of extension of the first portion 92a' of the holding grooves 92, which makes it possible to optimize the space; it preferably has an at least partly parallelepiped shape.This clearance may be at least partly through in a direction parallel to X3-X3 or to the axis 43 (this can be seen in figure 9C where it opens onto the surface onto which the through conduits 90 open and on which guides 166i, 1662 can be positioned as explained below); it may comprise, as can be seen in figure 9A, a widened part 194a (along a plane perpendicular to the longitudinal axis X3-X3 of the central axis 43), not through, which allows the passage of the terminal removal tools; c) and / or the second portion 92b, which extends for example over a foot 62 of the console, being in particular parallel to the longitudinal axis X3-X3 of the central axis, can be provided with entry chamfers 192'b (on the side of the lugs which will be connected to the card 12) which make it possible to improve the prepositioning of the lugs before the insertion of the lugs into the console.
[0087] As regards the housing 65 of the fixed part of the detector, here again, one or more improvements can be made: a') guides I661, 1662 (figures 9B and 9C), for example in the form of longitudinal extension ribs, can be provided in the upper part of the housing 65 to limit the axial play of the fixed part 52 of the detector when it is introduced into the housing 65; for reasons of economy of space, these guides can be of different dimensions, one I662 of them being for example of a length less than that of the other I661, for example to allow the through conduits 90 to open;b') and / or the device comprises means 168 for stopping, for example a central pillar, the travel of the detector in the housing 65, these means 168 for stopping being able to comprise chamfers 1681, 1682 (figure 9C), for example on the sides of the central pillar 168, which make it possible to bring the fixed part of the detector into abutment against it; these chamfers 168i, 168z preferably have an extension parallel to the longitudinal axis X3-X3 of the central axis 43; c') and / or the width of the pillar 168 can be provided to center the fixed part of the detector;d') and / or centering and / or holding means, for example one or more lateral bosses or notches 170i, 170? (figures 9C, 9D), may be provided on the head of the clip 70, which allow(s) to center and / or hold the fixed part of the detector. Figure 9D shows the correct positioning of the fixed part of the detector 52 in its housing, thanks at least to the presence of the chamfers 168i, 1682 and the bosses 170i, 1702.;
[0088] Thanks to the console 6 according to the invention, the electrical and mechanical connection of the position detector 5 to the geared motor 1 is facilitated, while mechanically protecting the position detector 5 and the electrical connection of the position detector 5 to the geared motor 1, and while protecting the position detector 5 and the electrical connection of the position detector 5 to the geared motor 1 against electromagnetic disturbances. In particular, the position detector 5 and the electrical connection of the position detector 5 to the geared motor 1 are better protected from vibrations.
[0089] Finally, the compactness of the geared motor 1 is increased, while having a satisfactory mass of the geared motor 1 and a high reduction of the reducer 3. In particular, the reducer 3 is more compact than a multi-stage gear reducer of known structure, while tending to increase the reduction of the reducer 3 at equivalent mass of these reducers.
[0090] Of course, various modifications can be made by those skilled in the art to the invention which has just been described without departing from the scope of the disclosure of the invention.
[0091] Alternatively, the geared motor 1 is used, for example, to drive an electric vehicle, such as an electric bicycle.
[0092] Alternatively, the electric motor 2 is, for example, a brushed motor. The electric motor 2 is, for example, single-phase or three-phase. Alternatively, the reducer 3 comprises at least one non-stepped gear in addition to the output gear 38, for example two toothed wheels.
[0093] Alternatively, the electronic motor card 12 is located below the electric motor 2, between the electric motor 2 and the bottom of the housing 10.
[0094] Additionally or alternatively, the position detector 5 detects the angular position of another gear 32, 34, 36 of the reducer 3 than the output gear 38.
[0095] Alternatively, the fixed part 51 of the position detector contributes to delimiting the upper surface of the console 6 by being flush with the upper surface SI of the base 60.
