  The conventional opening / closing body driving device described in Patent Document 1 has an advantage that the sliding door can be opened and closed manually by stopping the power supply to the electromagnetic clutch and disabling the clutch. However, since it has an expensive electromagnetic clutch, a drive device also becomes expensive.

  In order to obtain an inexpensive driving device, it is conceivable that the electromagnetic clutch is omitted, and the motor and the output drum are directly linked only by the mechanical linkage means. In the case of transmission to the output drum by the worm and worm wheel, when the motor becomes inoperable due to an electrical system failure or the like, it becomes impossible to rotate the output drum by rotating the motor idle. It may be difficult to manually open and close the electrical system, making it impossible to repair the electrical system.

  The present invention has been made in view of the above problems, and it is not necessary to use an expensive electromagnetic clutch, and even when the motor becomes inoperable due to a failure of the electric system, the opening / closing body can be easily operated by manual operation. An object of the present invention is to provide an inexpensive vehicle opening / closing drive device that can be opened and closed.

According to the present invention, the above problem is solved as follows.
(1) In a vehicle opening / closing body drive device in which an opening / closing body supported to be openable / closable by a vehicle body is opened / closed by a motor, the drive rotation body driven by the motor and the pivot of the drive rotation body rotate An output rotator that is freely pivoted and linked to the opening / closing body, a base rotator that rotates integrally with the drive rotator, and a base rotator that is movable in a direction that engages and disengages the output rotator. A linkage member that links the drive rotator and the output rotator, and a linkage member that is linked to the linkage member and that releases the linkage member from the output rotator by an external operation. A manual operation plate that can be moved to block the linkage between the drive rotator and the output rotator, the manual operation plate is provided with a plurality of rotation grooves, and one side of the output rotator is provided on one side. On the covering base plate A kick portion corresponding to the rotational locus of the rotary Domizo, providing arcuate window hole.

( 2 ) In the above item ( 1 ), a pair of linking members are provided on both sides of the pivot so as to be substantially symmetrical with each other.

( 3 ) In the above item (1) or (2) , the base rotating plate and the manual operation plate are fitted to the pivot in the cylindrical output rotating body, and the linking member is attached to the output rotating body. The base rotating plate is provided so as to be movable in the radial direction so that it can be engaged with and disengaged from the engaging portion provided on the inner peripheral surface.

(4) above (1) to (3) Oite to any one of Items, the linkage member pivotally attached rotatably to the base rotor plate, the end opposite its pivot point, the base rotor plate A linking pin projecting toward the manual operation plate is inserted through the provided radial hole, and the projecting end of the linking pin is slidably fitted to the manual operation plate; and When the manual operation plate is rotated in one direction against the biasing means, the linkage pin relatively moves from one end portion to the other end portion, whereby the linkage member and the output rotating body A guide slot that can be disengaged is provided.

( 5 ) In the above item ( 4 ), a part of the outer peripheral surface of the linkage pin is fitted and stopped at one end of the guide slot, so that the linkage pin becomes the other end of the guide slot. The locking recess is provided to temporarily prevent the locking member and the output rotating body from being disengaged from each other.

According to the present invention, the following effects can be achieved.
(A) According to the first aspect of the present invention, the driving force of the motor is normally transmitted to the output rotating body by the action of the linkage member provided on the base rotating body that rotates integrally with the driving rotating body, so The body can be opened and closed automatically.

Further, even if the motor becomes inoperable due to, for example, an electric system failure or the like, by manually operating the manual operation plate from the outside , the linkage between the output rotating body and the driving rotating body can be cut off. Therefore, the opening / closing body can be easily opened / closed manually. Therefore, an expensive electromagnetic clutch or the like is not required, and an inexpensive drive device can be provided. Further, by inserting a rod-like tool into the rotation groove of the manual operation plate through the window hole of the base plate, the manual operation plate can be easily rotated while the drive device is mounted on the vehicle. .

( B ) According to the invention described in claim 2, since a pair of linkage members are provided, the driving force when the motor is rotated forward and backward can be transmitted to the output rotating body in a balanced manner.

( C ) According to the invention described in claim 3 , the base rotating plate and the manual operation plate are accommodated in the cylindrical output rotating body, and the linkage member provided on the base rotating plate is also included in the output rotating body. Since the engaging portion is engaged with and disengaged from the engaging portion on the peripheral surface, the intermittent means does not protrude in the axial direction, and the overall dimension of the driving device in the axial direction is reduced, so that the size can be reduced.

( D ) According to the invention described in claim 4, by simply rotating the manual operation plate in one direction, the linkage member that is always engaged with the output rotating body can be smoothly moved in the direction of releasing the engagement. And it can be reliably rotated.

( E ) According to the invention of claim 5 , since the linkage member can be temporarily held in the disengaged state, even if the manual operation plate is not held while being rotated in one direction, The opening / closing body can be manually opened and closed.

Then, the projecting end portions are movably fitted to a pair of guide long holes (34) (34) drilled on both sides of the manual operation plate (31) sandwiching the pivot (13). It is linked.

  As shown in FIG. 7, both long holes (33) of the base rotating plate (26) face the radial direction substantially orthogonal to the angular shaft portion (24), and the shaft hole (35) for inserting the pin (27). It is formed in an arc shape centering on (35).

  As shown in FIG. 8, the guide long holes (34) of the manual operation plate (31) have a direction in which one end approaches the shaft hole (36) and the other end moves away from the shaft hole (36). And is substantially arc-shaped and point-symmetric with respect to the shaft hole (36).

  The length in the radial direction of both long holes (33) of the base rotating plate (26) is substantially the same as the range of the rotation locus centering on the shaft holes (36) at both ends of both guide long holes (34). (Refer to FIGS. 5 and 6), the movement region of the linkage pin (32) fitted in the guide slot (34) and the rotation range of the linkage member (28) integrated therewith are as follows. Therefore, the lengths of the long holes (33) in the radial direction may be long.

  Although the details will be described later on the inner edge of the outer end of the guide hole (34) on the side close to the shaft hole (36), when the manual operation plate (31) is manually rotated, the above-mentioned A locking recess (34a) that temporarily prevents the linkage pin (32) from moving toward the other end of the guide slot (34) is formed. Note that the locking recess (34a) does not need to be provided in both guide long holes (34), and even if provided only in one guide long hole (34), the movement of the linkage pin (32) is temporarily prevented. be able to.

  Between the base rotating plate (26) and the manual operation plate (31), a torsion spring (37) as a biasing means is loosely fitted to the bush (29), and a foot piece (37a) at one end thereof is The inwardly engaging piece (38) projecting at the center of the outer peripheral surface between the shaft holes (35) and (35) in the plate (26) and the foot piece (37b) at the other end are manually operated. A part between the guide long holes (34) of the plate (31) is cut into a square shape in the centripetal direction, and each of the outward locking pieces (39) projecting on the outer peripheral surface of the inner part thereof, It is locked. As a result, the manual operation plate (31) is always urged counterclockwise as viewed from the side with respect to the base rotation plate (26), and as shown in FIG. It is located at the outer end of both long holes (33) of (26) and at the outer end away from the pivot (13) in both guide long holes (34) of the manual operation plate (31). As a result, the two linking members (28) are always biased outward and rotated.

  A plurality of U-shaped rotating grooves (40) are formed on the outer peripheral surface of the manual operation plate (31) at predetermined intervals in the circumferential direction.

  As shown in FIGS. 2 and 4, two arc-shaped window holes (41) and (41) are formed in a portion of the base plate (11) corresponding to the rotation locus of the rotation groove (40). By inserting the rod-shaped tool (42) inserted from one of the window holes (41) into any one of the rotating grooves (40), the manual operation plate (31) is resisted against the torsion spring (37). Thus, it can be manually rotated in the clockwise direction when viewed from the side.

  An engaging claw (28a) is formed on the outer peripheral end of the both linking members (28) on the side of the linking pin (32), which is slightly outward and has an acute angle. Due to the biasing force of the spring (37), the linkage pin (32) is positioned at the outer end of the long hole (33) of the base rotating plate (26), so the tips of both engaging claws (28a) In (16), it is engaged with a pair of engaging grooves (43) (43) formed on the inner surface of the thick wall portion (16b) at the inner inner surface.

  In the driving device (6) of the above embodiment, when the motor (9) is rotated, the worm wheel (14) is rotated by the worm (10) fixedly fitted to the rotating shaft (9a), and the worm wheel is rotated. The pivot (13) is also rotated via the drive plate (20) which is substantially integral with (14).

  When the pivot (13) rotates, the base rotating plate (26) fitted to the angular shaft (24) and a pair of linkage members (28) (28) pivotally attached to the pin (27). Then, the intermittent means (17) comprising the manual operation plate (31) linked to both the linkage members (28) via the linkage pins (32) also rotates integrally.

  Further, as described above, the manual operation plate (31) is urged counterclockwise in a side view with respect to the base rotation plate (26) by the torsion spring (37), and as shown in FIG. (32) has moved to the outer ends of both long holes (33) of the base rotating plate (26) and both guide long holes (34) of the manual operation plate (31). ) And the linkage member (28) integrated with the pin (27) rotate outward about the pin (27), and the engaging claw (28a) at the tip thereof is a pair of engaging grooves ( 43) It rushes into and prevents the output drum (16) from rotating independently.

  Therefore, when the pivot (13) is rotated by the forward / reverse rotation of the motor (9), the output drum (16) is also rotated around the pivot (13) via both linkage members (28) of the intermittent means (17). The slide door (1) is opened and closed by winding the wire (15a) (or (15b)) wound around the output drum (16).

  On the other hand, when the operation of the motor (9) becomes impossible due to a failure of the electric system or the like, the slide door (1) can be manually opened and closed as follows.

  First, the opening / closing lid (not shown) provided in the vicinity of the drive device (6) in the inner panel of the vehicle body is removed so that the window hole (41) provided in the base plate (11) of the drive device (6) can be seen from the outside. To do.

  Next, as shown in FIGS. 2 and 4, the tip of the rod-like tool (42) inserted through one of the window holes (41) is inserted into any of the rotation grooves (40) of the manual operation plate (31). And is rotated clockwise in a side view.

  Then, as shown in FIGS. 3 and 6, the manual operation plate (31) is rotated clockwise against the urging force of the torsion spring (37), and both the long holes (33) and the guide long holes ( The link pins (32) located at the outer ends of (34) move relatively to the inner ends of the long holes (33), (34), so that both link members ( 28) is forcibly rotated inward about the pin (27).

As a result, the front ends of the engaging claws (28a) of the two linking members (28) are separated from the engaging grooves (43) on the inner surface of the output drum (16), and the worm wheel (14) and the pivot (13) When the transmission of the driving force between the output drums (16) is interrupted, the output drum (16) can freely rotate around the pivot (13).
Therefore, the sliding door (1) can be easily opened and closed by manual operation.

  When the linkage pin (32) moves to the inner end of the guide slot (34), it enters and stops in the locking recess (34a) provided at the end, and moves toward the other end. Therefore, it is not necessary to keep the manual operation plate (31) rotated with the rod-shaped tool (42), and the rod-shaped tool (42) is pulled out or released. Thus, the sliding door (1) can be opened and closed.

  When the repair of the electrical system is completed, the bar-shaped tool (42) is again fitted into one of the rotating grooves (40) of the manual operation plate (31), and the manual operation plate (31) is turned counterclockwise. What is necessary is just to rotate. Thereby, each member of the intermittent means (17) returns to the state of FIG. 5, and the sliding door (1) can be opened and closed again by the rotation of the motor (9).

  Even if the output drum (16) is manually rotated and the engaging groove (43) and the engaging claw (28a) of the linking member (28) do not face each other, the linking member (28) remains outward. Therefore, when the base rotating plate (26) is rotated by the motor (9), the engaging claw (28a) automatically engages with the engaging groove (43).

  As described above, in the driving device (6) of the above embodiment, the pivot (13) rotating integrally with the worm wheel (14) driven by the motor (9) and the output drum (16) are provided. An intermittent means (17) is provided between the pivot (13) and the motor (9) by rotating the manual operation plate (31) from the outside in a direction in which the linkage with the output drum (16) is cut off. ) Forcibly cuts off the driving force transmission path between the driving system and the output drum (16) until the sliding door (1) can be opened and closed manually. It is not necessary to use an electromagnetic clutch, and the sliding door (1) can be opened and closed by manual operation even if the motor (9) becomes inoperable due to a failure of the electrical system.

The present invention is not limited to the above embodiment.
In the above embodiment, the intermittent means (17) is provided between the pivot (13) and the output drum (16), but the drive plate (20) and the output which are substantially integrated with the worm wheel (14). It can also be provided between the drum (16). In this case, for example, the output drum (16) is provided opposite to the left and right so that the cylinder portion is on the left side, and a base rotation plate similar to the base rotation plate (26) is attached to the side surface of the drive plate (20). The base rotating plate may be provided with the same linking member (28) as described above, and the manual operation plate (31) may be linked with the linking pin (32) as described above.

One of them may be omitted. At this time, the engagement claw (28a) of the linkage member (28) and the engagement groove (43) of the output drum (16) are prevented so that the output drum (16) does not rotate in any direction in a normal state. What is necessary is just to change a shape suitably.

  Further, in the above-described embodiment, the linkage member (28) is rotated by the manual operation plate (31) to be engaged with and disengaged from the output drum (16) .For example, the linkage member (28) is linked to the base rotation plate (26). The member is provided so as to be movable in the radial direction, and the linkage member and the manual operation plate (31) are linked by a link mechanism or the like that changes the rotational movement of the manual operation plate (31) into a linear motion, and the manual operation plate (31).
