Description

[Technical field]

[0001] The present invention relates to a vehicle opening / closing body drive device that drives an opening / closing body such as a door or a tailgate provided in a vehicle. [Background technology]

[0002] Conventionally, there has been known a vehicle opening / closing body drive device that drives an opening / closing body such as a door or a tailgate provided in a vehicle. In general, the vehicle opening / closing body drive device includes an electric motor module capable of outputting rotational power, a connecting / disconnecting module provided in a power transmission path and switchable between a connected state and a disconnecting state, a reduction gear module that reduces the rotational power, and an output module. In the vehicle opening / closing body drive device, the rotational power output from the electric motor module is transmitted to the output module via the connecting / disconnecting module and the reduction gear module, and the output module is operated to drive the opening / closing body provided in the vehicle.

[0003] For example, Patent Document 1 discloses a vehicle opening / closing body drive device in which an electric motor module, two reduction gear modules, and an output module are arranged side by side on approximately the same axis. Also, for example, Patent Document 2 discloses a vehicle opening / closing body drive device in which an electric motor module is arranged on a first axis, and an actuator module is arranged on a second axis parallel to the first axis. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6458923 [Patent Document 2] Patent No. 6676512 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the vehicle opening / closing body drive device described in Patent Document 1, the electric motor module, the two reduction gear modules, and the output module are arranged side by side on approximately the same axis, so that the dimension in the axial direction is large. In this case, in the vehicle opening / closing body drive device described in Patent Document 1, the electric motor module, the two reduction gear modules, and the output module are specially designed so that they can be arranged side by side on approximately the same axis. Therefore, in order to reduce the dimension in the axial direction, for example, to make it possible to arrange the electric motor module and the two reduction gear modules on different axes, it is necessary to change the design of the electric motor module and the two reduction gear modules.

[0006] On the other hand, in the vehicle opening / closing body drive device described in Patent Document 2, the electric motor module is arranged on the first axis, and the actuator module is arranged on the second axis parallel to the first axis, so that the dimension in the direction perpendicular to the first axis and the second axis is large. In this case, in the vehicle opening / closing body drive device described in Patent Document 2, the electric motor module and the actuator module are specially designed so that the electric motor module can be arranged on the first axis, and the actuator module can be arranged on the second axis. Therefore, in order to reduce the dimension in the direction perpendicular to the first axis and the second axis, for example, to make it possible to arrange the electric motor module and the actuator module on approximately the same axis line, it is necessary to change the design of the electric motor module and the actuator module.

[0007] As described above, the vehicle opening / closing body drive device described in Patent Documents 1 and 2 cannot change its overall shape without changing the design of each module, making it difficult to improve layout suitability on the vehicle while reducing costs.

[0008] The present invention provides a vehicle opening / closing body drive device that can share each module of the vehicle opening / closing body drive device to reduce costs and improve layout flexibility on the vehicle. [Means for solving the problem]

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle opening / closing body drive device according to the present invention will now be described with reference to the accompanying drawings. The drawings are to be viewed in the direction indicated by the reference numerals.

[0014] The vehicle opening / closing body drive device 100 of this embodiment is a device that drives an opening / closing body such as a door provided in a vehicle.

[0015] 1 and 2, the vehicle opening / closing body drive device 100 includes an electric motor module 200 capable of outputting rotational power, a connection / disconnection module 300 provided in a power transmission path and switchable between a connected state and a disconnected state, a speed reducer module 400 that reduces the rotational power, and an output module 500. Furthermore, the vehicle opening / closing body drive device 100 includes a conversion module 600 having an input gear 610 to which the rotational power is input, and an output gear 620 that outputs the rotational power of a rotation shaft different from the rotation shaft of the rotational power input to the input gear 610.

[0016] The vehicle opening / closing body drive device 100 transmits rotational power output from the motor module 200 via the disconnecting module 300 and the reduction gear module 400 to the output module 500, and the output module 500 operates to drive the opening / closing body provided in the vehicle.

[0017] 1(a), the electric motor module 200 has an electric motor case 210, an electric motor (not shown) housed inside the electric motor case 210, and a drive shaft 220 that rotates integrally with a rotor of the electric motor to output rotational power. The electric motor case 210 has a generally cylindrical shape that is generally coaxial with the drive shaft 220. The drive shaft 220 protrudes to one axial side from an output side surface 201, which is an axial end surface on one side of the electric motor case 210 having a generally cylindrical shape.

[0018] As shown in FIG. 1B, the disconnecting module 300 has an input shaft 310 and an output shaft 320. The disconnecting module 300 is provided in a power transmission path and has a clutch mechanism that can be switched between a connected state and a disconnected state. In this embodiment, the input shaft 310 and the output shaft 320 are provided to be coaxial. The input shaft 310 protrudes from an input side surface 301, which is an end surface on one side in the axial direction of the input shaft 310 and the output shaft 320 of the disconnecting module 300, to one side in the axial direction of the input shaft 310 and the output shaft 320. The output shaft 320 protrudes from an output side surface 302, which is an end surface on the other side in the axial direction of the input shaft 310 and the output shaft 320 of the disconnecting module 300 and faces the input side surface 301, to the other side in the axial direction of the input shaft 310 and the output shaft 320. When the clutch mechanism of the connecting / disconnecting module 300 is in an engaged state, the power transmission path of the connecting / disconnecting module 300 is in a connected state, and the rotational power input to the input shaft 310 is transmitted and output from the output shaft 320. When the clutch mechanism of the connecting / disconnecting module 300 is in a disengaged state, the power transmission path of the connecting / disconnecting module 300 is in a cut-off state, and the rotational power input to the input shaft 310 is not transmitted to the output shaft 320. An external spline 311 is formed on the outer circumferential surface of the lower end of the input shaft 310. The output shaft 320 is integrated with a sun gear of a first-stage planetary gear mechanism in the reduction gear module 400 described later.

[0019] As shown in FIG. 1(c), the reducer module 400 has an output shaft 420. In this embodiment, the reducer module 400 has, for example, a two-stage planetary gear mechanism. The reducer module 400 reduces the rotational power input from the output shaft 320 of the disconnecting module 300 and outputs it to the output shaft 420. In this embodiment, the reducer module 400 is a two-stage planetary gear mechanism. The two-stage planetary gear mechanisms of this embodiment share a ring gear. The ring gear is fixed to a first housing 700 or a second housing 800, which will be described later. The sun gear of the first-stage planetary gear mechanism is provided on the output shaft 320 of the disconnecting module 300. The output shaft 320 of the disconnecting module 300 is connected to the reducer module 400 from an input side surface 401. The output shaft 420 protrudes from an output side surface 402 opposite to the input side surface 401. In this embodiment, the reduction gear module 400 is connected to the disconnecting module 300 such that the output shaft 320 of the disconnecting module 300 and the output shaft 420 of the reduction gear module 400 are coaxial. The rotational power output from the output shaft 320 of the disconnecting module 300 is transmitted to the sun gear of the first-stage planetary gear mechanism. The sun gear of the second-stage planetary gear mechanism is connected to the planetary carrier of the first-stage planetary gear mechanism and rotates integrally with the planetary carrier of the first-stage planetary gear mechanism. The output shaft 420 is connected to the planetary carrier of the second-stage planetary gear mechanism and rotates integrally with the planetary carrier of the second-stage planetary gear mechanism. Therefore, the reduction gear module 400 reduces the rotational power input from the output shaft 320 of the disconnecting module 300 in two stages by the two-stage planetary gear mechanism, and outputs it from the output shaft 420.

[0020] 2(a1) to 2(a3), the output module 500 includes a plurality of types of output modules 500. The vehicle opening / closing body drive device 100 can select any one of the plurality of types of output modules 500.

[0021] In this embodiment, the output module 500 includes a first output module 510 (see (a1) of FIG. 2) having an output arm 511 that rotates by the rotational power input from the output shaft 420 of the reduction gear module 400, a second output module 520 (see (a2) of FIG. 2) having an output gear 521 that rotates by the rotational power input from the output shaft 420 of the reduction gear module 400, and a third output module 530 (see (a3) ​​of FIG. 2) having a rack-and-pinion mechanism 531 that operates by the rotational power input from the output shaft 420 of the reduction gear module 400. The first output module 510, the second output module 520, and the third output module 530 can all be connected to the output side 402 of the reduction gear module 400.

[0022] For example, when a hinged door (swing door) is driven by the vehicle opening / closing body drive device 100, the first output module 510 is selected and the hinge mechanism of the hinged door is connected to the output arm 511. Also, when a sliding door that slides by a belt unit is driven by the vehicle opening / closing body drive device 100, the second output module 520 is selected and the output gear 521 is connected to the belt drive device of the sliding door. Also, when a sliding door that slides by a rack and pinion is driven by the vehicle opening / closing body drive device 100, the rack portion of the rack and pinion mechanism 531 is fixed to the sliding door.

[0023] 2(b), the conversion module 600 outputs rotational power having a rotation axis parallel to and different from the rotation axis of the rotational power input to the input gear 610. The conversion module 600 includes a conversion module housing 630 that houses the input gear 610 and the output gear 620.

[0024] The input gear 610 has a cylindrical large-diameter gear portion 611 having a rotation axis parallel to and different from the rotation axis of the rotational power input to the input gear 610, and a small-diameter gear portion 612 extending cylindrically from one axial end face of the large-diameter gear portion 611 and centered on the same rotation axis as the large-diameter gear portion 611, having the same rotation axis as the large-diameter gear portion 611, and having a smaller diameter than the large-diameter gear portion 611. Both the large-diameter gear portion 611 and the small-diameter gear portion 612 are external gears having teeth formed on their outer circumferential surfaces. The input gear 610 is rotatably supported by an input gear shaft (not shown) provided in the conversion module housing 630.

[0025] The output gear 620 has a cylindrical gear portion 621 having a rotation axis of the rotational power input to the input gear 610 and a rotation axis parallel to and different from the rotation axis of the input gear 610, and a coupling portion 622 extending from one axial end face of the gear portion 621 in a hollow cylindrical shape centered on the rotation axis of the gear portion 621 and having a hollow cylindrical shape with a smaller diameter than the gear portion 621. The gear portion 621 is an external gear with teeth formed on the outer circumferential surface. The hollow cylindrical coupling portion 622 has a spline groove formed on the inner circumferential surface. The output gear 620 is rotatably supported by an output gear shaft (not shown) provided in the conversion module housing 630.

[0026] The rotational power input to the conversion module 600 is input to the large diameter gear portion 611 of the input gear 610. The gear portion 621 of the output gear 620 is meshed with the small diameter gear portion 612 of the input gear 610. Therefore, when the rotational power is input to the conversion module 600 and the input gear 610 rotates, the output gear 620 also rotates accordingly. At this time, the rotational power input to the conversion module 600 is input to the large diameter gear portion 611 of the input gear 610, while the gear portion 621 of the output gear 620 is meshed with the small diameter gear portion 612 of the input gear 610, so that the rotational power input to the conversion module 600 is reduced in speed by the input gear 610 and the output gear 620 and then transmitted. Therefore, the conversion module 600 reduces the speed of the input rotational power and outputs the rotational power of a rotational axis that is parallel to and separate from the rotational axis of the rotational power input to the input gear 610 and is coaxial with the rotational axis of the output gear 620.

[0027] The conversion module housing 630 has a cover wall portion 631 that covers one axial side of the input gear 610 and the output gear 620, a side wall portion 632 that bends from the outer edge of the cover wall portion 631 and extends toward the other axial side of the input gear 610 and the output gear 620 to cover the sides of the input gear 610 and the output gear 620, and a flange portion 633 that extends from the end of the side wall portion 632 on the other axial side of the input gear 610 and the output gear 620 approximately perpendicular to the axial direction of the input gear 610 and the output gear 620. The cover wall portion 631, the side wall portion 632, and the flange portion 633 are integrally molded and are formed of, for example, resin. The conversion module housing 630 has an opening on the other axial end side of the input gear 610 and the output gear 620.

[0028] (Assembly of each module) 3 and 4 , the output side 201 of the motor module 200 is connectable to the input side 301 of the disconnection module 300, and is connectable to the conversion module 600. The input side 301 of the disconnection module 300 is connectable to the output side 201 of the motor module 200, and is connectable to the conversion module 600. The output side 302 of the disconnection module 300 is connectable to the input side 401 of the speed reducer module 400. The output side 402 of the speed reducer module 400 is connectable to the output module 500.

[0029] Therefore, as shown in FIG. 3, the vehicle opening / closing body drive device 100 is capable of connecting the output side 201 of the motor module 200 to the conversion module 600, connecting the input side 301 of the disconnection module 300 to the conversion module 600, connecting the output side 302 of the disconnection module 300 to the input side 401 of the reduction gear module 400, and connecting the output side 402 of the reduction gear module 400 to the output module 500.

[0030] At this time, the electric motor module 200 is connected to the conversion module 600 by attaching the drive gear 230 to the drive shaft 220 of the electric motor module 200 and meshing the drive gear 230 with the large diameter gear portion 611 of the input gear 610 of the conversion module 600. Furthermore, the connection / disconnection module 300 is connected to the conversion module 600 by spline-connecting the external spline 311 formed on the input shaft 310 of the connection / disconnection module 300 to the connection portion 622 of the output gear 620 of the conversion module 600. Then, the connection / disconnection module 300 and the reduction gear module are connected to each other by connecting the output shaft 320 of the connection / disconnection module 300 to the reduction gear module 400, and the output shaft 420 of the reduction gear module 400 to the output module 500, thereby connecting the reduction gear module 400 to the output module 500.

[0031] In this way, the vehicle opening / closing body drive device 100 incorporates the conversion module 600 on the power transmission path that transmits the rotational power output from the motor module 200 to the output module 500, making it possible to connect the motor module 200, the disconnection module 300, the reduction gear module 400, and the output module 500.

[0032] At this time, the vehicle opening / closing body drive device 100 has the electric motor module 200 and the disconnecting module 300 arranged in a direction perpendicular to the axial direction of the drive shaft 220 of the electric motor module 200 and the input shaft 310 and the output shaft 320 of the disconnecting module 300. In the vehicle opening / closing body drive device 100, the drive shaft 220 of the electric motor module 200 forms a first axis L1. On the other hand, the input shaft 310 and the output shaft 320 of the disconnecting module 300 and the output shaft 420 of the reduction gear module 400 are coaxial and form a second axis L2 that is parallel to and separate from the first axis L1. The electric motor module 200 is arranged so as to at least partially overlap at least one of the disconnecting module 300, the reduction gear module 400, and the output module 500 in the axial direction of the first axis L1 and the second axis L2. This allows the axial dimensions of the first shaft L1 and the second shaft L2 in the vehicle opening / closing body drive device 100 to be shortened.

[0033] On the other hand, as shown in FIG. 4, the vehicle opening / closing body drive device 100 can omit the conversion module 600 and connect the output side 201 of the motor module 200 to the input side 301 of the disconnection module 300, connect the output side 302 of the disconnection module 300 to the input side 401 of the reduction gear module 400, and connect the output side 402 of the reduction gear module 400 to the output module 500.

[0034] At this time, a connecting member 240 that connects the drive shaft 220 of the motor module 200 and the input shaft 310 of the disconnecting module 300 is attached to the electric motor module 200. In this embodiment, the connecting member 240 is a two-stage planetary gear mechanism. A sun gear of the first-stage planetary gear mechanism is connected to the drive shaft 220 of the electric motor module 200. A planetary carrier of the first-stage planetary gear mechanism is fixed to a second housing 800 described later. A ring gear of the first-stage planetary gear mechanism is connected to a sun gear of the second-stage planetary gear mechanism, and the sun gear of the second-stage planetary gear mechanism rotates integrally with the ring gear of the first-stage planetary gear mechanism. The planetary carrier of the second-stage planetary gear mechanism is fixed to a second housing 800 described later, similar to the planetary carrier of the first-stage planetary gear mechanism. The ring gear of the second-stage planetary gear mechanism is connected to a hollow shaft having a spline groove formed on its inner circumferential surface, and the hollow shaft rotates integrally with the ring gear of the second-stage planetary gear mechanism. The spline groove formed on the inner circumferential surface of the hollow shaft is meshed with an external spline 311 formed on an input shaft 310 of the disconnecting module 300, and the drive shaft 220 of the electric motor module 200 is connected to the input shaft 310 of the disconnecting module 300 via a connecting member 240.

[0035] In this manner, the vehicle opening / closing body drive device 100 can omit the conversion module 600 and can couple the electric motor module 200, the connection / disconnection module 300, the reduction gear module 400, and the output module 500.

[0036] At this time, the vehicle opening / closing body drive device 100 has the electric motor module 200, the connecting / disconnecting module 300, the reduction gear module 400, and the output module 500 arranged in a line in any one direction. This allows the vehicle opening / closing body drive device 100 to reduce the dimension in a direction perpendicular to the direction in which the electric motor module 200, the connecting / disconnecting module 300, the reduction gear module 400, and the output module 500 are arranged in a line. In this embodiment, in the vehicle opening / closing body drive device 100, the drive shaft 220 of the electric motor module 200, the input shaft 310 and the output shaft 320 of the reduction gear module 400, and the output shaft 420 of the reduction gear module 400 are the same shaft and form a third shaft L3. The vehicle opening / closing body drive device 100 can reduce the dimension in a direction perpendicular to the third shaft L3.

[0037] In this manner, the vehicle opening / closing body drive device 100 can select whether to incorporate the conversion module 600 or omit it.

[0038] Furthermore, the opening / closing body drive device 100 for vehicles further includes a first housing 700 (see FIGS. 5 and 6) that houses the electric motor module 200, the disconnecting module 300, and the reduction gear module 400 and is connectable to the output module 500 and the conversion module 600, and a second housing 800 (see FIGS. 9 and 10) that houses the electric motor module 200, the disconnecting module 300, and the reduction gear module 400 and is connectable to the output module 500. The opening / closing body drive device 100 for vehicles is capable of selecting either the first housing 700 or the second housing 800. In this embodiment, the first housing 700 is selected when the conversion module 600 is incorporated into a power transmission path that transmits rotational power from the electric motor module 200 to the output module 500, and the second housing 800 is selected when the conversion module 600 is omitted.

[0039] First, a case where the first housing 700 is selected, that is, a case where the conversion module 600 is incorporated into a power transmission path along which rotational power is transmitted from the electric motor module 200 to the output module 500, will be described.

[0040] As shown in Figures 5 and 6, the first housing 700 comprises a bottom wall portion 701, a first accommodating portion 710 having a cylindrical shape extending from the bottom wall portion 701 in a first direction D1, and a second accommodating portion 720 having a cylindrical shape adjacent to the bottom wall portion 701 in a direction perpendicular to the first direction D1 and extending from the bottom wall portion 701 in the first direction D1 parallel to the first accommodating portion 710.

[0041] A first opening 711 that opens from the bottom wall 701 in the first direction D1 is formed at an end of the first accommodating section 710 on the bottom wall 701 side in the first direction D1. A second opening 712 is formed at an end of the first accommodating section 710 opposite the bottom wall 701 side in the first direction D1. The first opening 711 is of a size and shape that allows the drive shaft 220 of the electric motor module 200 to be inserted therethrough, but does not allow the electric motor case 210 to be inserted therethrough. The second opening 712 is of a size and shape that allows the electric motor module 200 including the electric motor case 210 to be inserted therethrough.

[0042] A first opening 721 that opens from the bottom wall 701 in the first direction D1 is formed at an end of the second accommodating section 720 on the bottom wall 701 side in the first direction D1. A second opening 722 is formed at an end of the second accommodating section 720 opposite the bottom wall 701 side in the first direction D1. The first opening 721 has a size and shape that allows the input shaft 310 of the disconnecting module 300 to be inserted therethrough, but does not allow the disconnecting module 300 to be inserted therethrough. The second opening 722 has a size and shape that allows the disconnecting module 300 and the reducer module 400 to be inserted therethrough.

[0043] 7 and 8, first, the electric motor module 200 is accommodated in the first accommodating portion 710.

The connector module 910 is assembled in the second opening 712 of the first housing 710 so that the connection terminal portion 912 is electrically connected to the plurality of wiring members arranged inside the first housing 700. As a result, the electric motor of the electric motor module 200 and the clutch mechanism of the disconnecting module 300 can be operated by power supplied from the outside via the connection terminal portion 912.

[0052] In this way, when the conversion module 600 is incorporated into the power transmission path through which rotational power is transmitted from the electric motor module 200 to the output module 500, the vehicle opening / closing body drive device 100 is assembled by accommodating the electric motor module 200, the disconnecting module 300, and the reducer module 400 in the first housing 700, assembling the electric motor module 200, the disconnecting module 300, and the reducer module 400 to the first housing 700, and then assembling the conversion module 600 and the output module 500 to the first housing 700.

[0054] Next, a case where the second housing 800 is selected, that is, where the conversion module 600 is omitted, will be described.

[0055] As shown in Fig. 9 and Fig. 10, the second housing 800 has a cylindrical shape extending in the second direction D2, and has a first end 801 on one side of the second direction D2 and a second end 802 on the other side of the second direction D2. The second housing 800 has a substantially cylindrical accommodation section 810 with a bottom extending in the second direction D2. A bottom wall section 811 is formed at an end on one side of the accommodation section 810 in the second direction D2, and an opening section 812 is formed at an end on the other side of the accommodation section 810 in the second direction D2. The bottom wall section 811 of the accommodation section 810 is formed at the first end section 801 of the second housing 800, and the opening section 812 is formed at the second end section 802 of the second housing 800.

[0056] 11, when the second housing 800 is selected, that is, when the conversion module 600 is omitted, first, the electric motor module 200 and the connecting member 240 are connected. The connecting member 240 is connected to the electric motor module 200 so as to face the output side surface 201, and the drive shaft 220 of the electric motor module 200 is connected to the sun gear of the first stage planetary gear mechanism of the connecting member 240.

[0057] Next, the connector module 920 is engaged with the electric motor module 200. The connector module 920 has a board unit 921 having a substantially disk shape with a diameter substantially the same as that of the electric motor case 210 of the electric motor module 200, and a connection terminal portion 922 to which a conductor member such as a harness for electrically connecting with an external device is connected. The board unit 921 is electrically connected to the connection terminal portion 922 by a wiring member such as a conductor.

The board unit 921 is engaged with the surface of the electric motor module 200 opposite to the output side surface 201, and is connected to a plurality of wiring members arranged inside the second housing 800. The plurality of wiring members arranged inside the second housing 800 include a wiring member connected to the electric motor of the electric motor module 200 and a wiring member connected to a clutch mechanism of the disconnecting module 300. Therefore, by engaging the board unit 921 with the surface of the electric motor module 200 opposite the output side surface 201 and connecting it to a plurality of wiring members arranged inside the second housing 800, the electric motor of the electric motor module 200 and the clutch mechanism of the disconnecting module 300 can be operated by power supplied from the outside via the connection terminal portion 922.

The connection terminal portion 922 of the connector module 920 is disposed on the opposite side to the electric motor module 200 across the board unit 921.

[0058] As a result, the electric motor module 200, the connecting member 240, and the connector module 920 are integrated together.

[0059] 12 and 13, the unit in which the electric motor module 200, the connecting member 240, and the connector module 920 are integrated is then accommodated in the accommodating section 810 of the second housing 800. At this time, the unit in which the electric motor module 200, the connecting member 240, and the connector module 920 are integrated is accommodated in the accommodating section 810 from the opening 812 with the connector module 920 facing the bottom wall section 811 and the connecting member 240 facing the opening 812. A through hole 811a is formed in the bottom wall section 811 of the accommodating section 810 of the second housing 800, into which the connection terminal section 922 of the connector module 920 can be fitted. Then, the connection terminal portion 922 of the connector module 920 is fitted into the through hole 811a formed in the bottom wall portion 811 so that the connection terminal portion 922 of the connector module 920 is exposed to the outside of the second housing 800 from the through hole 811a, and the unit in which the electric motor module 200, the coupling member 240, and the connector module 920 are integrated is assembled to the second housing 800. In a state in which the unit in which the electric motor module 200, the coupling member 240, and the connector module 920 are integrated is assembled to the second housing 800, both of the planetary carriers of the first and second stage planetary gear mechanisms of the coupling member 240 are engaged with the second housing 800.

[0060] Next, the disconnecting module 300 is accommodated in the accommodation section 810. At this time, the disconnecting module 300 is accommodated in the accommodation section 810 from the opening 812 with the input side surface 301 facing the bottom wall section 811 and the output side surface 302 facing the opening 812. The disconnecting module 300 is accommodated in the accommodation section 810 with the input side surface 301 facing the connecting member 240. Then, the external spline 311 formed on the input shaft 310 of the disconnecting module 300 is engaged with a spline groove formed on the inner circumferential surface of a hollow shaft that rotates integrally with the ring gear of the second stage planetary gear mechanism of the connecting member 240, and the disconnecting module 300 is assembled to the second housing 800.

[0061] Next, the reducer module 400 is accommodated in the accommodation section 810. At this time, the reducer module 400 is accommodated in the accommodation section 810 from the opening 812 with the input side surface 401 facing the bottom wall section 811 and the output side surface 402 facing the opening 812. The reducer module 400 is accommodated in the accommodation section 810 with the input side surface 401 facing the output side surface 302 of the disconnecting module 300. Then, the reducer module 400 is coupled to the output shaft 320 of the disconnecting module 300, and the reducer module 400 is assembled to the second housing 800 with the output shaft 420 of the reducer module 400 protruding from the second end portion 802 of the second housing 800 in the second direction D2.

[0062] Next, the output module 500 is assembled to the second housing 800. The output module 500 is assembled to the second housing 800 so as to close the opening 812 of the accommodating portion 810. At this time, the output module 500 is assembled to the second housing 800 so that the output shaft 420 of the reduction gear module 400 is connected to the output module 500.

[0063] In this way, when the conversion module 600 is omitted, the vehicle opening / closing body drive device 100 is assembled by accommodating the electric motor module 200, the disconnecting module 300, and the reduction gear module 400 in the second housing 800, assembling the electric motor module 200, the disconnecting module 300, and the reduction gear module 400 to the second housing 800, and then assembling the output module 500 to the second housing 800. By assembling the electric motor module 200, the disconnecting module 300, and the reduction gear module 400 to the second housing 800 in this way, the electric motor module 200, the disconnecting module 300, and the reduction gear module 400 can be integrated, thereby improving the ease of assembly of the vehicle opening / closing body drive device 100.

[0064] The second housing 800 is provided with a plurality of mounting portions 820 in which nut members are embedded, and the second housing 800 is fixed to the body of the vehicle by fastening members such as bolts fastened to the mounting portions 820. In this way, the vehicle opening / closing body drive device 100 is fixed to the body of the vehicle. At this time, the electric motor module 200, the disconnecting module 300, and the reduction gear module 400 are assembled to the second housing 800, and the electric motor module 200, the disconnecting module 300, and the reduction gear module 400 are integrated, improving the ease of handling when assembling the vehicle opening / closing body drive device 100 to the vehicle.

[0065] As described above, the vehicle opening / closing body drive device 100 is capable of connecting the motor module 200, the disconnection module 300, the reduction gear module 400, and the output module 500 by incorporating the conversion module 600 on the power transmission path along which the rotational power output from the motor module 200 is transmitted to the output module 500, and is also capable of connecting the motor module 200, the disconnection module 300, the reduction gear module 400, and the output module 500 without using the conversion module 600.

[0066] As a result, the vehicle opening / closing body drive device 100 can change its overall shape by selecting whether to incorporate the conversion module 600 or omit the conversion module 600 depending on the shape of the space in which it is installed in the vehicle, without changing the designs of the motor module 200, the connect / disconnect module 300, and the reducer module 400. As a result, the vehicle opening / closing body drive device 100 can improve the layout flexibility on the vehicle while reducing costs by sharing the motor module 200, the connect / disconnect module 300, and the reducer module 400.

[0067] Furthermore, in the vehicle opening / closing body drive device 100, when the conversion module 600 is incorporated on the power transmission path through which rotational power is transmitted from the electric motor module 200 to the output module 500, the first housing 700 is selected and the electric motor module 200, the disconnecting module 300 and the reducer module 400 are assembled to the first housing 700, thereby making it possible to integrate the electric motor module 200, the disconnecting module 300 and the reducer module 400. In addition, in the vehicle opening / closing body drive device 100, when the conversion module 600 is omitted, the second housing 800 is selected and the electric motor module 200, the disconnecting module 300 and the reducer module 400 are assembled to the second housing 800, thereby making it possible to integrate the electric motor module 200, the disconnecting module 300 and the reducer module 400. In this way, the vehicle opening / closing body drive device 100 can be constructed by selecting either the first housing 700 or the second housing 800 depending on whether the conversion module 600 is incorporated or omitted, and assembling the motor module 200, the disconnection module 300, and the reduction gear module 400 into either the first housing 700 or the second housing 800.In either case, the motor module 200, the disconnection module 300, and the reduction gear module 400 can be integrated, thereby improving the assemblyability of the vehicle opening / closing body drive device 100 and improving the handleability when assembling the vehicle opening / closing body drive device 100 to the body of the vehicle.

[0068] In addition, the output module 500 has a first output module 510, a second output module 520, and a third output module 530, and the first output module 510, the second output module 520, and the third output module 530 are all connected to the output shaft 420 of the reduction gear module 400 and can be assembled to either the first housing 700 or the second housing 800. Therefore, in the vehicle opening / closing body drive device 100, in either case where the conversion module 600 is incorporated into the power transmission path along which the rotational power output from the motor module 200 is transmitted to the output module 500 to connect the motor module 200, the disconnection module 300, the reduction gear module 400, and the output module 500, or where the conversion module 600 is omitted and the motor module 200, the disconnection module 300, the reduction gear module 400, and the output module 500 are connected, any one of the first output module 510, the second output module 520, and the third output module 530 can be selected.

[0069] 3, 7, and 8 show a case where the first output module 510 is selected as the output module 500, but the second output module 520 and the third output module 530 can also be selected. Similarly, in FIGS. 4, 12, and 13, a case where the second output module 520 is selected as the output module 500, but the first output module 510 and the third output module 530 can also be selected.

[0070] As a result, the vehicle opening / closing body drive device 100 can select any one of the multiple types of output modules 500 depending on the type of opening / closing body to be driven. Therefore, the vehicle opening / closing body drive device 100 can drive different types of opening / closing bodies by sharing the electric motor module 200, the connecting / disconnecting module 300, and the reduction gear module 400. As a result, different types of opening / closing bodies can be driven without changing the design of the electric motor module 200, the connecting / disconnecting module 300, and the reduction gear module 400, thereby reducing costs.

[0071] Although one embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such an embodiment. It is clear that a person skilled in the art can come up with various modified or revised examples within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present invention. In addition, the components in the above embodiment may be arbitrarily combined within the scope of the invention.

[0072] For example, in this embodiment, the conversion module 600 is connected between the electric motor module 200 and the disconnecting module 300 in the power transmission path of the vehicle opening / closing body drive device 100 in which the rotational power output from the electric motor module 200 is transmitted to the output module 500, but the conversion module 600 may be connected, for example, between the disconnecting module 300 and the reducer module 400, or between the reducer module 400 and the output module 500 in the power transmission path of the vehicle opening / closing body drive device 100.

[0073] In addition, for example, in the present embodiment, the power transmission path of the vehicle opening / closing body drive device 100 is connected in the order of the electric motor module 200, the reducer module 400, the disconnecting module 300, and the output module 500, but the power transmission path of the vehicle opening / closing body drive device 100 may be connected in the order of the electric motor module 200, the reducer module 400, the disconnecting module 300, and the output module 500. In this case, the conversion module 600 may be connected, for example, between the electric motor module 200 and the reducer module 400, between the reducer module 400 and the disconnecting module 300, or between the disconnecting module 300 and the output module 500 in the power transmission path of the vehicle opening / closing body drive device 100.

[0074] Also, for example, in this embodiment, when the second housing 800 is selected, i.e., when the conversion module 600 is omitted, the electric motor module 200 is connected to the connecting member 240, and the input shaft 310 of the disconnection module 300 is connected to the connecting member 240, so that the electric motor module 200 and the disconnection module 300 are connected via the connecting member 240, but the connecting member 240 can be omitted. That is, the drive shaft 220 of the electric motor module 200 may be directly connected to the input shaft 310 of the disconnection module 300.

[0075] Also, for example, in this embodiment, the connecting member 240 is a two-stage planetary gear mechanism, but the connecting member 240 may be a reduction mechanism that reduces the rotational power output from the motor module 200 at a predetermined reduction ratio depending on the specifications such as the required output.

[0076] Also, for example, in this embodiment, the connecting / disconnecting module 300 has a clutch mechanism, but the connecting / disconnecting module 300 may have a brake mechanism that is provided in the power transmission path and can be switched between a connected state and a disconnected state. When the connecting / disconnecting module 300 has a brake mechanism, the power transmission circuit is braked so as not to rotate by setting the brake mechanism of the connecting / disconnecting module 300 to a connected state (brake state), and the door can be held in any position, and when the brake mechanism of the connecting / disconnecting module 300 is set to a disconnected state, the power transmission circuit is set to a state in which it can freely rotate, and the door can be opened and closed manually and electrically.

[0077] Also, for example, in this embodiment, the vehicle opening / closing body drive device 100 is equipped with an electric motor module 200, a disconnecting module 300, a reduction gear module 400, and an output module 500, but the vehicle opening / closing body drive device 100 may omit the disconnecting module 300.

Also, when the conversion module is omitted, the motor module, the disconnecting module, and the reducer module can be integrated by assembling them in the second housing, improving the assembling property of the vehicle opening / closing body drive device and improving the handling property when assembling the vehicle opening / closing body drive device to the body of the vehicle. In this way, the vehicle opening / closing body drive device can be configured by selecting either the first housing or the second housing depending on whether the conversion module is incorporated or omitted, and assembling the motor module, the disconnect module, and the reducer module into either the first housing or the second housing.In either case, the motor module, the disconnect module, and the reducer module can be integrated, thereby improving the assemblyability of the vehicle opening / closing body drive device and improving the handleability when assembling the vehicle opening / closing body drive device to the vehicle body.

[0086] According to (4), when the conversion module is incorporated in the power transmission path that transmits rotational power from the motor module to the output module, the motor module and the reducer module can be integrated by assembling them in the first housing, improving the ease of assembly of the vehicle opening / closing body drive device and improving the ease of handling when assembling the vehicle opening / closing body drive device to the body of the vehicle. Also, when the conversion module is omitted, the motor module and the reducer module can be integrated by assembling them in the second housing, improving the ease of assembly of the vehicle opening / closing body drive device and improving the ease of handling when assembling the vehicle opening / closing body drive device to the body of the vehicle. In this way, the vehicle opening / closing body drive device can be configured by selecting either the first housing or the second housing depending on whether the conversion module is incorporated or omitted, and assembling the motor module and the reduction gear module into either the first housing or the second housing, so that the motor module and the reduction gear module can be integrated in either case, thereby improving the assemblyability of the vehicle opening / closing body drive device and improving the handleability when assembling the vehicle opening / closing body drive device to the vehicle body.

[0087] (5) A vehicle opening / closing body drive device according to any one of (1) to (4), The output module includes a plurality of types of output modules (a first output module 510, a second output module 520, and a third output module 530), The opening / closing body drive device for a vehicle is capable of selecting any one of the plurality of types of output modules.

[0088] According to (5), the vehicle opening / closing body drive device can select any one of a plurality of types of output modules depending on the type of opening / closing body to be driven. Therefore, the vehicle opening / closing body drive device can drive different types of opening / closing bodies by sharing each module. This allows different types of opening / closing bodies to be driven without changing the design of each module, thereby reducing costs. [Explanation of symbols]
