Description

[Technical field]

[0001] The present invention relates to a sliding door drive device for opening and closing a sliding door of a vehicle or the like. [Background technology]

[0002] Conventionally, many minivans, wagons, and the like have adopted sliding doors as rear doors. In recent years, the opening and closing operations of the sliding doors have been automated. One of the general configurations of a vehicle door opening and closing device that automatically opens and closes a sliding door is known to include a rail member provided along the side of the body, a cable that opens and closes the door by being driven along the rail member, and a sliding door drive device for winding up the cable. In general, the sliding door drive device includes a motor as a power source, a reduction mechanism that reduces the rotation of the motor, and a rotating drum that is rotated by the reduction mechanism to wind up and pay out the cable.

[0003] In this type of sliding door drive device, when it is installed in a vehicle, in order to make it easier to route the cable to the sliding door, the cable connecting to the sliding door must be assembled in a slack state, and the slack in the cable must be eliminated after the sliding door drive device is assembled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the sliding door drive device of the present invention will be described with reference to the attached drawings. The drawings are to be viewed in the direction of the reference symbols. In this specification and the like, for the sake of simplicity and clarity, the front / rear, left / right, and up / down directions are described according to the direction as seen by the driver of the vehicle equipped with the sliding door drive device, and in the drawings, the front of the vehicle is indicated as Fr, the rear as Rr, the left as L, the right as R, the top as U, and the bottom as D.

[0012] 1, the sliding door drive device 20 is mounted on a vehicle V and slides a sliding door attached to the vehicle V to automatically open and close the sliding door. In this embodiment, the sliding door drive device 20 slides a sliding door 14 attached to the left side of the vehicle V in the front-rear direction to automatically open and close the sliding door 14.

[0013] The sliding door 14 is attached to the left side of the vehicle V and is slidable in the front-rear direction relative to the vehicle V. The sliding door 14 is supported at three points by an upper rail 16a, a center rail 16b, and a lower rail 16c, and opens and closes by sliding in the front-rear direction. The center rail 16b is provided at approximately the middle height in the up-down direction of a quarter panel 18 provided at the rear of the left side of the vehicle V.

[0014] The sliding door drive device 20 is disposed on the interior side of the quarter panel 18 and is fixed to the quarter panel 18 at a location close to the center rail 16b.

[0015] The sliding door drive device 20 includes an opening cable 21 and a closing cable 22. The sliding door 14 is provided with a support frame (not shown). One end of each of the opening cable 21 and the closing cable 22 is fixed to the support frame of the sliding door 14. The support frame includes running rollers that roll within the center rail 16b. The opening cable 21 and the closing cable 22 are, for example, stainless steel twisted wires. The sliding door drive device 20 opens and closes the sliding door 14 by winding and unwinding the opening cable 21 and the closing cable 22. The vehicle V is provided with a holding means for holding the sliding door 14 in a fully open or fully closed position.

[0016] As shown in Figures 2 and 5, the sliding door drive device 20 is a single unit that includes an opening cable 21 having one end connected to the sliding door 14, a closing cable 22 having one end connected to the sliding door 14, a drive motor 30, an ECU (Electric Control Unit) 40 that controls the drive motor 30, a reduction mechanism 50 that reduces the rotational power output from the drive motor 30, and an opening drum mechanism 61 and a closing drum mechanism 62 that engage with the reduction mechanism 50.

[0017] Hereinafter, for the sake of simplicity and clarity, the left-right direction will sometimes be referred to as the vehicle width direction, and the right side will sometimes be referred to as the inside side of the vehicle and the left side will sometimes be referred to as the outside side of the vehicle.

[0018] The sliding door drive device 20 includes a housing case 70 that houses the drive motor 30, the ECU 40, the speed reduction mechanism 50, the opening drum mechanism 61, and the closing drum mechanism 62. The housing case 70 has a base member 71, an exterior housing 72 that covers the exterior side of the base member 71, and an interior housing 73 that covers the interior side of the base member 71.

[0019] The base member 71 extends in the up-down direction and the front-rear direction.

[0020] 2 to 4, in the sliding door drive device 20, a drive motor 30 and an ECU 40 are disposed on the vehicle interior side of a base member 71. On the vehicle interior side of the base member 71, the drive motor 30 is fixed to an upper region of the base member 71, and the ECU 40 is disposed so as to surround the radial outside of a lower region of the drive motor 30 when viewed in the vehicle width direction from the vehicle interior side.

[0021] The driving motor 30 is, for example, a reversible motor that can instantly switch between forward and reverse rotation. The driving motor 30 is, for example, an inner rotor type, flat and thin brushless motor. When viewed from the axial direction of the driving motor 30, a plurality of mounting base portions 30a (three in this embodiment) having insertion holes 30b penetrating in the axial direction are provided along the circumferential direction at the radially outer end portion. The driving motor 30 is fixed to the base member 71 by inserting fastening members such as bolts through the insertion holes 30b of the mounting base portions 30a and fastening them to the base member 71.

[0022] In this embodiment, the drive motor 30 is an inner rotor type brushless motor, and since the coil is arranged on the outer periphery, it has excellent heat dissipation properties and small rotational inertia. Since the drive motor 30 is a brushless motor, it can be made flat, and is thinner than drive motors that have been used for this purpose in the past. The thinner drive motor 30 makes it easier to integrate it with the sliding door drive device 20.

[0023] As a characteristic of a brushless motor, the drive motor 30 can perform stop-hold control to generate a holding torque even in a stopped state. This allows the sliding door 14 to be held in a stopped state even on a somewhat inclined ground, and eliminates the need to provide a separate member (e.g., a clutch, etc.) for holding the position of the sliding door 14, allowing the sliding door drive device 20 to be made smaller and thinner. In addition, the drive motor 30 can perform step control like a stepping motor, providing excellent controllability and rotation accuracy. In addition, the drive motor 30 can be driven in a sine wave, reducing torque fluctuations.

[0024] In the case where the driving motor 30 needs to brake suddenly during the sliding operation of the sliding door 14, the above-mentioned stop holding control is performed to apply a forced braking force, thereby obtaining a strong braking force. Also, in the driving motor 30, the magnetic force of the permanent magnet can be changed by vector control, and high torque low rotation operation or low torque high rotation operation can be performed depending on the type of sliding door 14 and other specifications. Furthermore, high voltage low rotation control can obtain an operation like a stepping motor. Low voltage high rotation control can assist the manual opening and closing operation of the sliding door 14 in the manual opening and closing mode.

[0025] The ECU 40 is a device in which a control circuit board is covered with a case, and includes an inverter circuit for controlling the drive motor 30. The ECU 40 has a box shape having a thin thickness in the vehicle width direction. When viewed in the vehicle width direction from the inside of the vehicle, the ECU 40 has a substantially U-shape that opens upward so as to surround the radially outer side of the lower region of the drive motor 30. A connector 41 facing downward is provided on the lower surface of the ECU 40. A harness (not shown) is connected to the connector 41. The ECU 40 is supplied with power and a sensor signal from the harness via the connector 41. Since the connector 41 is provided on the lower surface of the ECU 40 so as to face downward, the harness can be connected to the connector 41 so as not to protrude in the vehicle width direction. The ECU 40 and the drive motor 30 are electrically connected by a three-phase wire 42, and the ECU 40 converts the power supplied from the harness and supplies three-phase power of U phase, V phase, and W phase to the drive motor 30.

[0026] The driving motor 30 and the ECU 40 have their exterior surfaces covered by a base member 71, and their interior surfaces and front, rear, top and bottom surfaces covered by an interior housing 73.

[0027] The interior housing 73 has an upper region fixed to the base member 71 at three fixing portions 731 using fastening members such as bolts, and a lower region fixed to the base member 71 at four points by engaging with four claw portions 711 extending from the base member 71 toward the interior side of the vehicle.

[0028] The lower end of the interior housing 73 has an opening 732 that opens downward. The connector 41 that faces downward is inserted into the opening 732, so that a harness (not shown) can be connected to the connector 41 from below.

[0029] 5 to 8, in the sliding door drive device 20, the speed reduction mechanism 50, the opening drum mechanism 61, and the closing drum mechanism 62 are arranged on the vehicle exterior side of the base member 71. On the vehicle exterior side of the base member 71, the speed reduction mechanism 50 is arranged side by side in the vehicle width direction so that the opening drum mechanism 61 and the closing drum mechanism 62 are arranged on the vehicle exterior side.

[0030] The drive motor 30 has a motor output shaft 31 that extends in the vehicle width direction toward the vehicle exterior. A motor output gear 32 is provided on the motor output shaft 31. The motor output shaft 31 passes through an insertion hole (not shown) provided in the base member 71 from the drive motor 30 provided on the vehicle interior side of the base member 71. The motor output gear 32 meshes with the reduction gear mechanism 50 that is arranged on the vehicle exterior side of the base member 71.

[0031] The reduction mechanism 50 reduces the rotation of the drive motor 30 and transmits it to the opening drum mechanism 61 and the closing drum mechanism 62. The reduction mechanism 50 includes an input side reduction gear 51 that meshes with the motor output gear 32, and an output side reduction gear 52 that is smaller in diameter and has fewer teeth than the input side reduction gear 51 and rotates coaxially with the input side reduction gear 51.

[0032] The input side reduction gear 51 is provided below the motor output gear 32 and meshes with the motor output gear 32 .

[0033] The output side reduction gear 52 is provided coaxially with the input side reduction gear 51 and on the vehicle outer side of the input side reduction gear 51. The output side reduction gear 52 is formed on a boss portion of the input side reduction gear 51.

[0034] The rotation shafts of the input side reduction gear 51 and the output side reduction gear 52 are located below the motor output shaft 31 and are parallel to the motor output shaft 31 .

[0035] The opening drum mechanism 61 includes an opening drum 611 and an opening drum input gear 612 that is provided on the vehicle interior surface of the opening drum 611 and rotates coaxially with the opening drum 611. The opening drum input gear 612 is attached to the vehicle interior surface of the opening drum 611. The rotation axes of the opening drum 611 and the opening drum input gear 612 are located obliquely above and rearward of the rotation axes of the input side reduction gear 51 and the output side reduction gear 52, and are parallel to the motor output shaft 31 and the rotation axes of the input side reduction gear 51 and the output side reduction gear 52.

[0036] The opening drum 611 has a flat cylindrical shape with the rotation axis as the center. The opening cable 21 is wound around the outer circumferential surface of the opening drum 611.

[0037] The opening drum input gear 612 is disk-shaped and has a larger diameter than the opening drum 611 , and meshes with the output side reduction gear 52 of the reduction mechanism 50 .

[0038] The closing drum mechanism 62 includes a closing drum 621 and a closing drum input gear 622 that is provided on the vehicle interior surface of the closing drum 621 and rotates coaxially with the closing drum 621. The closing drum input gear 622 is attached to the vehicle interior surface of the closing drum 621. The rotation axes of the closing drum 621 and the closing drum input gear 622 are located diagonally above and in front of the rotation axes of the input side reduction gear 51 and the output side reduction gear 52, and are parallel to the motor output shaft 31 and the rotation axes of the input side reduction gear 51 and the output side reduction gear 52.

[0039] The closing drum 621 has a flat cylindrical shape with the rotation axis as the center. The closing cable 22 is wound around the outer circumferential surface of the closing drum 621.

[0040] The closing drum input gear 622 is in the shape of a disk having a diameter larger than that of the closing drum 621 , and meshes with the output side reduction gear 52 of the reduction mechanism 50 .

[0041] In this embodiment, the opening drum mechanism 61 and the closing drum mechanism 62 have a shape and arrangement that are linearly symmetrical about a virtual straight line connecting the motor output shaft 31 and the rotation axes of the input side reduction gear 51 and the output side reduction gear 52, when viewed from the vehicle width direction.

[0042] One end of the opening cable 21 is connected to the sliding door 14 as described above, and the other end of the opening cable 21 is fixed to the outer circumferential surface of the opening drum 611. The opening cable 21 is wound around the outer circumferential surface of the opening drum 611 counterclockwise as viewed in the vehicle width direction from the vehicle exterior, starting from the other end. Therefore, when the opening drum 611 rotates counterclockwise as viewed in the vehicle width direction from the vehicle exterior, the opening cable 21 is unwound, and when the opening drum 611 rotates clockwise, the opening cable 21 is wound.

[0043] As described above, one end of the closing cable 22 is connected to the sliding door 14, and the other end of the closing cable 22 is fixed to the outer circumferential surface of the closing drum 621. The closing cable 22 is wound around the outer circumferential surface of the closing drum 621 in a clockwise direction as viewed in the vehicle width direction from the vehicle exterior, starting from the other end. Therefore, when the closing drum 621 rotates clockwise as viewed in the vehicle width direction from the vehicle exterior, the closing cable 22 is unwound, and when the closing drum 621 rotates counterclockwise, the opening cable 21 is wound.

[0044] A torsion coil spring 613 wound around the rotation axis of the opening drum 611 is housed inside the opening drum 611. One end of the torsion coil spring 613 is engaged with the opening drum input gear 612, and the other end of the torsion coil spring 613 is engaged with the opening drum 611. In the opening drum mechanism 61, the opening drum 611 is biased in the rotation direction of the side on which the opening cable 21 is wound relative to the opening drum input gear 612 by the elastic force of the torsion coil spring 613. In this embodiment, the opening drum 611 is biased in the clockwise direction relative to the opening drum input gear 612 when viewed in the vehicle width direction from the vehicle exterior side.

[0045] In the opening drum mechanism 61, when the opening drum input gear 612 rotates clockwise as viewed from the outside of the vehicle in the vehicle width direction, the opening drum 611 rotates clockwise together with the opening drum input gear 612, and the opening cable 21 is wound around it. On the other hand, when the opening drum input gear 612 rotates counterclockwise as viewed from the outside of the vehicle in the vehicle width direction, the opening drum 611 rotates counterclockwise in conjunction with the opening drum input gear 612 while balancing with the biasing force of the torsion coil spring 613, and the opening cable 21 is paid out.

[0046] Because the opening drum 611 is biased in the clockwise direction relative to the opening drum input gear 612 as viewed in the vehicle width direction from the outside of the vehicle, when an assembler of the sliding door drive device 20 pulls the opening cable 21 to pay out the opening cable 21, the opening drum input gear 612 does not rotate, and only the opening drum 611 rotates counterclockwise as viewed in the vehicle width direction from the outside of the vehicle against the biasing force of the torsion coil spring 613. Then, when an assembler of the sliding door drive device 20 releases the opening cable 21, the opening drum input gear 612 does not rotate, and only the opening drum 611 rotates clockwise as viewed in the vehicle width direction from the outside of the vehicle due to the biasing force of the torsion coil spring 613, returning to its original position. This makes it easier for an assembly worker to pull the opening cable 21 and pay out the opening cable 21 to perform the assembly work of the sliding door drive device 20, improving the ease of assembly of the sliding door drive device 20.

[0047] A torsion coil spring 623 wound around the rotation axis of the closing drum 621 is housed inside the closing drum 621. One end of the torsion coil spring 623 is engaged with the closing drum input gear 622, and the other end of the torsion coil spring 623 is engaged with the closing drum 621. In the closing drum mechanism 62, the closing drum 621 is biased in the rotation direction of the side on which the closing cable 22 is wound relative to the closing drum input gear 622 by the elastic force of the torsion coil spring 623. In this embodiment, the closing drum 621 is biased in the counterclockwise direction relative to the closing drum input gear 622 when viewed in the vehicle width direction from the vehicle exterior side.

[0048] In the closing drum mechanism 62, when the closing drum input gear 622 rotates counterclockwise as viewed in the vehicle width direction from the vehicle exterior, the closing drum 621 rotates counterclockwise together with the closing drum input gear 622, and the closing cable 22 is wound around it. On the other hand, when the closing drum input gear 622 rotates clockwise as viewed in the vehicle width direction from the vehicle exterior, the closing drum 621 rotates clockwise in conjunction with the closing drum input gear 622 while balancing with the biasing force of the torsion coil spring 623, and the closing cable 22 is paid out.

[0049] Because the closing drum 621 is biased in the counterclockwise direction relative to the closing drum input gear 622 when viewed in the vehicle width direction from the outside of the vehicle, when an assembler of the sliding door drive device 20 pulls the closing cable 22 to pay out the closing cable 22, the closing drum input gear 622 does not rotate, and only the closing drum 621 rotates clockwise when viewed in the vehicle width direction from the outside of the vehicle against the biasing force of the torsion coil spring 623. Then, when an assembler of the sliding door drive device 20 releases the closing cable 22, the closing drum input gear 622 does not rotate, and only the closing drum 621 rotates counterclockwise when viewed in the vehicle width direction from the outside of the vehicle due to the biasing force of the torsion coil spring 623, returning to its original position. This makes it easier for an assembly worker to pull the closing cable 22 and pay out the closing cable 22 to perform the assembly work of the sliding door drive device 20, improving the ease of assembly of the sliding door drive device 20.

[0050] When viewed from the vehicle exterior in the vehicle width direction, when the drive motor 30 rotates forward or backward and the motor output shaft 31 rotates clockwise, in the reduction mechanism 50, the input side reduction gear 51 meshing with the motor output gear 32 rotates counterclockwise, and the output side reduction gear 52 also rotates counterclockwise together with the input side reduction gear 51. Then, the opening drum input gear 612 of the opening drum mechanism 61 and the closing drum input gear 622 of the closing drum mechanism 62, which mesh with the output side reduction gear 52, both rotate clockwise. At this time, since the output side reduction gear 52 has a smaller diameter and fewer teeth than the input side reduction gear 51, the rotational power of the drive motor 30 is reduced by the reduction mechanism 50 and transmitted to the opening drum input gear 612 of the opening drum mechanism 61 and the closing drum input gear 622 of the closing drum mechanism 62. Then, when the opening drum input gear 612 of the opening drum mechanism 61 and the closing drum input gear 622 of the closing drum mechanism 62 both rotate clockwise, the opening drum 611 of the opening drum mechanism 61 rotates clockwise to wind the opening cable 21 onto the opening drum 611, and the closing drum 621 of the closing drum mechanism 62 rotates clockwise to unwind the closing cable 22 from the closing drum 621. This causes the sliding door 14 to perform an opening operation.

[0051] On the other hand, when viewed from the vehicle exterior in the vehicle width direction, when the drive motor 30 is driven in the reverse or forward direction and the motor output shaft 31 rotates counterclockwise, in the reduction mechanism 50, the input side reduction gear 51 meshing with the motor output gear 32 rotates clockwise, and the output side reduction gear 52 also rotates clockwise together with the input side reduction gear 51. Then, the opening drum input gear 612 of the opening drum mechanism 61 and the closing drum input gear 622 of the closing drum mechanism 62 meshing with the output side reduction gear 52 both rotate counterclockwise. At this time, since the output side reduction gear 52 has a smaller diameter and fewer teeth than the input side reduction gear 51, the rotational power of the drive motor 30 is reduced by the reduction mechanism 50 and transmitted to the opening drum input gear 612 of the opening drum mechanism 61 and the closing drum input gear 622 of the closing drum mechanism 62. Then, when the opening drum input gear 612 of the opening drum mechanism 61 and the closing drum input gear 622 of the closing drum mechanism 62 both rotate counterclockwise, the opening drum 611 of the opening drum mechanism 61 rotates counterclockwise to unwind the opening cable 21 from the opening drum 611, and the closing drum 621 of the closing drum mechanism 62 rotates counterclockwise to wind the closing cable 22 around the closing drum 621. This causes the sliding door 14 to close.

[0052] A plurality of first ribs 611a are formed on the end surface of the opening drum 611 on the vehicle exterior in the rotation axis direction, protruding outward in the rotation axis direction along the circumferential direction of the rotation axis. The plurality of first ribs 611a extend radially from the rotation axis center along the circumferential direction of the rotation axis of the opening drum 611. A first groove portion 611b recessed inward in the rotation axis direction is formed between adjacent first ribs 611a. The provision of the first groove portion 611b allows for weight reduction, while the provision of the first ribs 611a ensures strength.

[0053] A plurality of second ribs 621a are formed on the end surface of the closing drum 621 on the vehicle exterior side in the rotation axis direction, protruding outward in the rotation axis direction along the circumferential direction of the rotation axis. The plurality of second ribs 621a extend radially from the rotation axis center along the circumferential direction of the rotation axis of the closing drum 621. Second grooves 621b recessed inward in the rotation axis direction are formed between adjacent second ribs 621a. The second grooves 621b can be provided to reduce weight, while the second ribs 621a can ensure strength.

[0054] As shown in Figures 9 to 11, the reduction mechanism 50, the opening drum mechanism 61, and the closing drum mechanism 62 have their inside surfaces covered by a base member 71, and their outside surfaces and the front, rear, upper and lower surfaces covered by an outside housing 72.

[0055] The exterior housing 72 is fixed to the base member 71 at five fixing portions 72a by fastening members such as bolts.

[0056] The exterior housing 72 has a base portion 720 corresponding to the exterior surface of the base member 71, an opening drum accommodating portion 721 cylindrically recessed from the base portion 720 toward the exterior side of the vehicle and accommodating the opening drum mechanism 61, a closing drum accommodating portion 722 cylindrically recessed from the base portion 720 toward the exterior side of the vehicle and accommodating the closing drum mechanism 62, an opening cable accommodating portion 723 extending obliquely upward from the rear upper portion of the opening drum accommodating portion 721 and covering the exterior side, upper side, and lower side of the opening cable 21, and a closing cable accommodating portion 724 extending obliquely upward from the front upper portion of the closing drum accommodating portion 722 and covering the exterior side, upper side, and lower side of the closing cable 22. The reduction mechanism 50 is accommodated between the base portion 720 of the exterior housing 72 and the base member 71.

[0057] A first drainage port 721a is provided at the lower end of the surface of the opening drum accommodating portion 721 facing the vehicle exterior, for discharging liquid such as water that has entered the opening drum accommodating portion 721. The first drainage port 721a is a hole penetrating the opening drum accommodating portion 721 in the vehicle width direction, and is provided at a position overlapping with a part of the opening drum 611 when viewed in the direction of the rotation axis of the opening drum 611 from the vehicle exterior.

[0058] A second drainage port 722a is provided at a lower end of the outer surface of the closing drum accommodating portion 722, for discharging liquid such as water that has entered the inside of the closing drum accommodating portion 722. The second drainage port 722a is a hole penetrating the closing drum accommodating portion 722 in the vehicle width direction, and is provided at a position overlapping with a part of the closing drum 621 when viewed in the direction of the rotation axis of the closing drum 621 from the outer side of the vehicle.

[0059] The vehicle exterior housing 72 of the storage case 70 is provided with a restricting member 80 below the opening drum accommodating portion 721 and the closing drum accommodating portion 722 .

[0060] The regulating member 80 is provided between the opening drum 611 and the closing drum 621 in the front-rear direction, which is the direction in which the opening drum 611 and the closing drum 621 are arranged.

[0061] The regulating member 80 rotates about a rotation axis that is perpendicular to both the rotation axis of the opening drum 611 and the rotation axis of the closing drum, and is parallel to a virtual line VL1 that passes through the rotation axis of the opening drum 611 and the rotation axis of the closing drum 621. In this embodiment, the rotation axis of the opening drum 611 and the rotation axis of the closing drum both extend in the vehicle width direction, and the rotation axis of the opening drum 611 and the rotation axis of the closing drum 621 are aligned in the front-rear direction, so that the virtual line VL1 extends in the front-rear direction. Therefore, in this embodiment, the regulating member 80 rotates about a rotation axis that extends in the front-rear direction.

[0062] The regulating member 80 includes a first snap portion 81 that can engage with the opening drum 611 by being inserted into the first groove portion 611b of the opening drum 611 to regulate the rotation of the opening drum 611, and a second snap portion 82 that can engage with the closing drum 621 by being inserted into the second groove portion 621b of the closing drum 621 to regulate the rotation of the closing drum 621.

[0063] When the regulating member 80 is rotated in the clockwise direction as viewed from the rear by an assembly worker or the like, the first snap portion 81 passes through the first drainage port 721a of the exterior housing 72, enters the inside of the opening drum accommodating portion 721 and is inserted into the first groove portion 611b of the opening drum 611, thereby engaging with the opening drum 611, and the second snap portion 82 passes through the second drainage port 722a of the exterior housing 72, enters the inside of the closing drum accommodating portion 722 and is inserted into the second groove portion 621b of the closing drum 621, thereby engaging with the closing drum 621. As a result, the rotation of both the opening drum 611 and the closing drum 621 is regulated by the regulating member 80.

[0064] In this way, the regulating member 80 is inserted into the first groove portion 611b of the opening drum 611 and the second groove portion 621b of the closing drum 621 and engages with the opening drum 611 and the closing drum 621, thereby being able to regulate the rotation of both the opening drum 611 and the closing drum 621.

[0065] In addition, when the regulating member 80 is rotated counterclockwise as viewed from the rear by an assembly worker or the like from a state in which it is inserted into the first groove portion 611b of the opening drum 611 and the second groove portion 621b of the closing drum 621 and engaged with the opening drum 611 and the closing drum 621, it disengages from the opening drum 611 and the closing drum 621, and the first snap portion 81 and the second snap portion 82 also disengage from the opening drum accommodating portion 721 and the closing drum accommodating portion 722, respectively.

[0066] In this manner, the regulating member 80 is provided so as to be engageable with and detachable from the opening drum 611 and the closing drum 621.

[0067] Therefore, when an assembly worker of the sliding door drive device 20 pulls the opening cable 21, the opening drum 611 rotates counterclockwise as viewed in the vehicle width direction from the vehicle exterior against the biasing force of the torsion coil spring 613, and the opening cable 21 is let out. Similarly, when an assembly worker of the sliding door drive device 20 pulls the closing cable 22, the closing drum 621 rotates clockwise as viewed in the vehicle width direction from the vehicle exterior against the biasing force of the torsion coil spring 623, and the closing cable 22 is let out. In this state, when an assembly worker rotates the regulating member 80 in the clockwise direction as viewed from the rear, the first snap portion 81 is inserted into the first groove portion 611b of the opening drum 611 and engages with the opening drum 611, and the second snap portion 82 is inserted into the second groove portion 621b of the closing drum 621 and engages with the closing drum 621. As a result, the rotation of both the opening drum 611 and the closing drum 621 is regulated by the regulating member 80, and the opening cable 21 and the closing cable 22 are maintained in the reeled out state.

[0068] The rotation of both the opening drum 611 and the closing drum 621 is restricted by the restricting member 80, the opening cable 21 and the closing cable 22 are maintained in a reeled state, and the sliding door drive device 20 is assembled to the vehicle V in a state in which the opening cable 21 and the closing cable 22 are slackened. After the assembly of the sliding door drive device 20 to the vehicle V is completed, when an assembly worker or the like rotates the restricting member 80 in a counterclockwise direction as viewed from the rear, the restricting member 80 is detached from the opening drum 611 and the closing drum 621. Then, the opening drum 611 rotates in the rotation direction of the side on which the opening cable 21 is wound, that is, in a clockwise direction as viewed in the vehicle width direction from the vehicle exterior, by the biasing force of the torsion coil spring 613, and winds up the opening cable 21, so that the slack in the opening cable 21 is eliminated. Similarly, the closing drum 621 rotates in the direction of the side on which the closing cable 22 is wound, that is, counterclockwise when viewed in the vehicle width direction from the outside of the vehicle, due to the biasing force of the torsion coil spring 623, thereby winding up the closing cable 22, thereby eliminating slack in the closing cable 22.

[0069] In this way, the sliding door drive device 20 is equipped with a regulating member 80 capable of regulating the rotation of both the opening drum 611 and the closing drum 621, and the single regulating member 80 can maintain and eliminate the slack state of both the opening cable 21 and the closing cable 22, thereby suppressing an increase in the number of parts and labor required.

[0070] In addition, the regulating member 80 includes a first snap portion 81 that can be inserted into the first groove portion 611b of the opening drum 611 to engage with the opening drum 611 and regulate the rotation of the opening drum 611, and a second snap portion 82 that can be inserted into the second groove portion 621b of the closing drum 621 to engage with the closing drum 621 and regulate the rotation of the closing drum 621. Therefore, it is not necessary to newly process the opening drum 611 and the closing drum 621 for the portions where the regulating member 80 engages. This reduces the manufacturing cost of the slide door drive device 20. In addition, if the operation of removing the regulating member 80 from the opening drum 611 and the closing drum 621 is forgotten after the installation of the slide door drive device 20 to the vehicle V is completed, the rotation of both the opening drum 611 and the closing drum 621 remains regulated by the regulating member 80, so that the slide door 14 does not operate even if the slide door drive device 20 is driven. This makes it possible to recognize that the operation of removing the regulating member 80 from the opening drum 611 and the closing drum 621 has been forgotten, thereby preventing the operation of removing the regulating member 80 from the opening drum 611 and the closing drum 621 from being forgotten.

[0071] Furthermore, in the exterior housing 72, the first drainage port 721a and the second drainage port 722a can also be used as insertion ports for the first snap portion and the second snap portion 82 of the restricting member 80, respectively, so that the processing costs of the exterior housing 72 can be reduced.

[0072] Furthermore, when an installer of the sliding door drive device 20 operates the regulating member 80, no alignment is required, and the rotation of both the opening drum 611 and the closing drum 621 can be easily and reliably regulated by simply rotating the regulating member 80, thereby improving the ease of assembly when assembling the sliding door drive device 20 to the vehicle V.

[0073] The first snap portion 81 has a first leg portion 81a and a second leg portion 81b formed to be spaced apart from each other in the rotation direction of the opening drum 611, which in this embodiment is the front-rear direction at the lower end of the opening drum 611. In this embodiment, the first leg portion 81a is located in the front, and the second leg portion 81b is located in the rear, and the first leg portion 81a and the second leg portion 81b are formed to be spaced apart from each other in the front-rear direction. The first leg portion 81a and the second leg portion 81b are inserted into the first groove portion 611b of the opening drum 611 to restrict the rotation of the opening drum 611. This allows the weight of the restricting member 80 to be reduced.

[0074] In addition, when viewed from the outside of the vehicle in the vehicle width direction, when the opening drum 611 attempts to rotate counterclockwise, the first leg 81a elastically abuts against the first rib 611a of the opening drum 611 to restrict the counterclockwise rotation of the opening drum 611, and if the rotational force is large, the first leg 81a abuts against the second leg 81b to restrict the rotation, and when the opening drum 611 attempts to rotate clockwise, the second leg 81b elastically abuts against the first rib 611a of the opening drum 611 to restrict the counterclockwise rotation of the opening drum 611, and if the rotational force is large, the second leg 81b abuts against the first leg 81a to restrict the rotation. This allows the rotation of the opening drum 611 to be regulated by distributing the load between the first leg 81a and the second leg 81b, and allows the first leg 81a and the second leg 81b to elastically receive the load when they come into contact with the first rib 611a.

[0075] Similarly, the second snap portion 82 has a third leg 82a and a fourth leg 82b formed to be spaced apart from each other in the rotation direction of the closing drum 621, which in this embodiment is the front-rear direction at the lower end of the closing drum 621. In this embodiment, the third leg 82a is located in the front, and the fourth leg 82b is located in the rear, and the third leg 82a and the fourth leg 82b are formed to be spaced apart from each other in the front-rear direction. The third leg 82a and the fourth leg 82b are inserted into the second groove 621b of the closing drum 621 to restrict the rotation of the closing drum 621. This allows the weight of the restricting member 80 to be reduced.

[0076] In addition, when viewed from the outside of the vehicle in the vehicle width direction, when the closing drum 621 attempts to rotate counterclockwise, the third leg 82a elastically abuts against the second rib 621a of the closing drum 621 to restrict the counterclockwise rotation of the closing drum 621, and if the rotational force is large, the third leg 82a abuts against the fourth leg 82b to restrict the rotation, and when the closing drum 621 attempts to rotate clockwise, the fourth leg 82b elastically abuts against the second rib 621a of the closing drum 621 to restrict the counterclockwise rotation of the closing drum 621, and if the rotational force is large, the fourth leg 82b abuts against the third leg 82a to restrict the rotation. This allows the rotation of the closing drum 621 to be regulated by distributing the load between the third leg 82a and the fourth leg 82b, and the third leg 82a and the fourth leg 82b can elastically absorb the load when they come into contact with the second rib 621a.

[0077] The restricting member 80 is provided with a claw portion 83 that engages with the vehicle-exterior housing 72 of the accommodation case 70. In this embodiment, the claw portion 83 is provided in each of a front region and a rear region of the restricting member 80. Therefore, in this embodiment, the restricting member 80 is provided with two claw portions 83 aligned in the front-rear direction.

[0078] An engagement portion 725 with which the claw portion 83 of the restricting member 80 can engage is provided at a lower end portion of the exterior-side housing 72. In this embodiment, two engagement portions 725 are provided at the lower end portion of the exterior-side housing 72 aligned in the front-rear direction, corresponding to the two claw portions 83 aligned in the front-rear direction provided on the restricting member 80.

[0079] Each claw portion 83 of the regulating member 80 engages with a corresponding engagement portion 725 of the exterior housing 72 at a position where the regulating member 80 is disengaged from the opening drum 611 and the closing drum 621 (in this embodiment, the first snap portion 81 and the second snap portion 82 are also disengaged to the outside of the opening drum accommodating portion 721 and the closing drum accommodating portion 722, respectively), thereby holding the regulating member 80 in the position where it is disengaged from the opening drum 611 and the closing drum 621 (see Figure 11).

[0080] This prevents the regulating member 80 from being displaced at a position separated from the opening drum 611 and the closing drum 621 after the sliding door drive device 20 is assembled to the vehicle V, thereby preventing the regulating member 80 from being displaced and colliding with other members or generating abnormal noises from the regulating member 80 after the sliding door drive device 20 is assembled to the vehicle V.

[0081] Outside the sliding door drive device 20, the opening cable 21 is housed in a hollow portion of a tube-shaped opening outer casing 231. An opening casing cap 241 is fitted onto one end of the opening outer casing 231.

[0082] In the exterior housing 72, an opening casing cap 241 engages with a front upper end surface 723a of the opening cable housing portion 723. One end of the opening outer casing 231 is fixed to the exterior housing 72 by the opening casing cap 241 engaging with the front upper end surface 723a of the exterior housing 72.

[0083] Outside the sliding door drive device 20, the closing cable 22 is housed in a hollow portion of a tubular closing outer casing 232. A closing casing cap 242 is fitted onto one end of the closing outer casing 232.

[0084] In the exterior housing 72, a closing casing cap 242 engages with a rear upper end surface 724a of the closing cable housing 724. One end of the closing outer casing 232 is fixed to the exterior housing 72 by the closing casing cap 242 engaging with the rear upper end surface 724a of the exterior housing 72.

[0088] Also, for example, in this embodiment, the regulating member 80 regulates the rotation of both the opening drum 611 and the closing drum 621, but the worker who installs the sliding door drive device 20 may pull the opening cable 21 to pay out more of the opening cable 21 than in this embodiment, and the regulating member 80 may regulate only the rotation of the opening drum 611, or may pull the closing cable 22 to pay out more of the closing cable 22 than in this embodiment, and the regulating member 80 may regulate only the rotation of the closing drum 621.

[0089] Furthermore, for example, in this embodiment, the regulating member 80 is provided in the alignment direction of the opening drum 611 and the closing drum 621, i.e., between the opening drum 611 and the closing drum 621 in the front-to-back direction, but the regulating member 80 is not limited to being provided in the alignment direction of the opening drum 611 and the closing drum 621, and may be provided, for example, between the opening drum 611 and the closing drum 621 from a functional standpoint.
