Description

Door latch release force transmission mechanism

The present invention relates to a door latch releasing force transmission mechanism capable of releasing a latch by transmitting a door latch releasing force from a door handle provided on a vehicle door to a latch mechanism capable of latching a vehicle door in a closed state.

In recent years, a door latch release force transmission mechanism capable of transmitting not only a door handle but also a door latch release force from a release actuator to a latch mechanism has become widespread (see, for example, Patent Document 1). As one of the door latch release force transmission mechanisms of this type, a second, intermediate rotation among the first, second, and third rotation levers that sequentially transmits and rotates the door latch release force from the door handle. It is known that a release actuator is connected to the lever and a latch mechanism is connected to the rearmost third pivot lever. Further, the relay member is movably assembled between the lock position and the unlock position on the third rotation lever, and the second rotation is performed only when the relay member is disposed at the unlock position. The door latch releasing force can be transmitted from the dynamic lever to the third pivot lever, and when the relay member is placed in the lock position, the second pivot lever and the third pivot lever are shut off and the door latch is engaged. The release force is not transmitted, and the door handle and release actuator lock the door so that it can not be opened.

Unexamined-Japanese-Patent No. 2010-31569 (Paragraph [0076], [0077])

By the way, a vehicle with a release actuator is rapidly spreading due to the convenience that the vehicle door can be easily opened even with a luggage or the like. However, when the conventional door latch release force transmission mechanism is in the locked state, not only between the door handle and the latch mechanism but also between the release actuator and the latch mechanism is shut off. In the case of using the release actuator, as in the case of using the door handle, the unlocking operation had to be performed in advance. That is, in the conventional door latch release force transmission mechanism, when riding on a vehicle in a locked state, two operations of a lock release operation and a switch operation of the release actuator are required, which is a convenience of using the release actuator. There is a problem that the sex is halved.

The door latch release force transmission mechanism according to claim 1 includes a handle interlock lever, an actuator interlock lever, and a latch release output lever, wherein the handle interlock lever is pivoted only by the door latch release force from the door handle, and the actuator interlock The lever pivots only with the door latch release force from the release actuator. Then, when the relay member is disposed at the unlock position, the latch release output lever is rotated by any door latch release force of the handle interlock lever and the actuator interlock lever and outputs the door latch release force to the latch mechanism. That is, in the unlocked state in which the relay member is disposed at the unlocked position, the latch of the vehicle door by the latch mechanism is released by any one operation of the door handle operation or the switch operation of the release actuator. On the other hand, when the relay member assembled to the latch release output lever is disposed at the lock position, the latch release output lever is rotated only by the door latch release force from the actuator interlock lever and outputs the door latch release force to the latch mechanism. . That is, when using the door handle in the locked state where the relay member is disposed at the lock position, the latch mechanism is operated by two operations of the lock release operation of moving the relay member to the unlock position and the operation of the door handle. The vehicle door latch is released. On the other hand, when the release actuator is used in the locked state, the above-mentioned unlocking operation becomes unnecessary, and the latch of the vehicle door by the latch mechanism is released by only one operation of the switch of the release actuator. That is, when the release actuator is used, only one operation of the switch of the release actuator is required in order to release the latch of the door by the latch mechanism regardless of the unlock state and the lock state, which is more convenient than before Improve.

By the way, if the release actuator pivots the latch release output lever and the release actuator falls in a position where the latch mechanism releases the latch and becomes inoperable, the vehicle door can not be closed and returned to the latchable state, You will not be able to drive the vehicle. On the other hand, according to the door latch releasing force transmission mechanism of the second aspect of the present invention, the first contact portion of the actuator interlock lever that contacts the relay member in the unlock position and the second contact portion that contacts the relay member in the lock position. The release actuator rotates the latch release output lever, and the latch mechanism releases the latch, because a blocking portion is provided between the relay member to receive the relay member and block the door latch release force from the actuator interlock lever to the latch release output lever. In the case where the release actuator fails and becomes immobile in the above position, the relay member is disposed at an intermediate position between the lock position and the unlock position, and is received by the blocking portion, whereby the latch release output lever and latch mechanism Can be disconnected from the release actuator and the vehicle door can be closed back to a latchable state.

In the door latch releasing force transmission mechanism according to claim 3, the relay member is moved in the rotation radius direction of the actuator interlocking lever, and the blocking portion is opened between the first and second contact portions, and the pivoting radius of the actuator interlocking lever The relief groove extends in the direction intersecting with the direction, so when the latch release output lever and latch mechanism are separated from the release actuator, the latch can be released by the release actuator after latching the vehicle door in the closed state. It disappears. In addition, since the relay member is received in the escape groove, the relay member can not be disposed in the unlock position. On the other hand, according to the door latch releasing force transmission mechanism of the fourth aspect, the escape groove has a width such that the relay member can move to the first intermediate position on the rotating shaft side and the second intermediate position on the opposite side. At the same time, the steering wheel interlock lever is not in contact with the relay member in the second intermediate position but in contact with the relay member in the first intermediate position separately from the third contact portion in contact with the relay member in the unlock position. Since the fourth contact portion is provided, the relay member is received in the release groove, the latch release output lever and the latch mechanism are separated from the release actuator, and the vehicle door is latched in the closed state. By arranging, the door handle can release the latch of the vehicle door, and by arranging the relay member at the second intermediate position, the door handle can release the latch of the vehicle door. It is also possible to have a locked state.

Further, according to the configuration of claim 5, the flat surfaces provided on the side surface of the connecting pin and the side surface of the actuator interlock lever abut on each other to transmit the door latch releasing force, so transmission of the door latch releasing force Stabilize. According to the sixth aspect of the present invention, since the connecting pin is prevented from rotating in the guide elongated hole, the flat surfaces of the connecting pin and the actuator interlocking lever can be reliably brought into surface contact with each other.

The child lock operating portion 19 is rotatably supported by the mechanism board 101, and one end remote from the center of rotation is exposed from the end face of the vehicle door 90, and the other end remote from the center of rotation It is connected to the child lock pin 125. The child lock pin 125 is moved away from the main support shaft 102 by the rotation operation of the child lock operating portion 19 (a position shown by a two-dot chain line in FIG. 7) and a child unlock near the main support shaft 102. It moves to and from the position (the position shown by the solid line in FIG. 7). When in the child unlocking position, the child lock pin 125 is located within the pivoting area of the in-vehicle handle connecting lever 140, so the in-vehicle handle connecting lever 140 and the connecting pin penetrating lever 120 are the first via the child lock pin 125. It is connected integrally rotatably in the rotation direction. That is, it becomes possible to transmit the operation power by the opening operation of the in-vehicle door handle 18 from the in-vehicle handle connecting lever 140 to the connecting pin penetrating lever 120. On the other hand, at the child lock position, the child lock pin 125 is located outside the pivot area of the in-vehicle handle connecting lever 140, so the in-vehicle handle connecting lever 140 and the connecting pin through lever 120 are disengaged in an interlocking manner. That is, it becomes impossible to transmit the operation power by the opening operation of the in-vehicle door handle 18 from the in-vehicle handle connecting lever 140 to the connecting pin penetrating lever 120.

A switch pressing protrusion 128 is integrally formed on the connecting pin penetration lever 120. The switch pressing protrusion 128 protrudes toward the switch 111 (see FIG. 5) fixed to the mechanism board 101, and when the connecting pin penetrating lever 120 is pivoted in the first rotation direction, the switch pressing protrusion 128 Is to press the switch 111 (on).

As shown in FIG. 11, the latch release output lever 130 is provided with a pair of

lever projecting pieces

131 and 132 protruding in opposite directions from the main support shaft 102. Of the pair of

lever projections

131 and 132, the front end door lock device 10A and the rear side door are opened via the

open cables

91W and 92W at the tip of the lever projection 132 which protrudes to the same side as the in-vehicle handlebar connecting lever 140. The respective ratchets 30 of the locking device 10B are connected (see FIG. 5).

Of the latch release output lever 130, a guide long hole 133 extending in the rotational radial direction is formed through the lever projecting piece 131 superimposed on the lever projecting piece 121 of the connecting pin penetrating lever 120. The guide long hole 133 can be overlapped with the L-shaped first side path 123A of the connection pin through lever 120 when both the latch release output lever 130 and the connection pin through lever 120 are in the original position, and the guide long hole A common connection pin 400 passes through 133 and the L-shaped elongated hole 123. The connecting pin 400 is supported by a pair of side portions extending in the longitudinal direction of the guide long hole 133 and is capable of reciprocating in the guide long hole 133. The connection pin 400 corresponds to the "relay member" in the present invention.

Here, from the side edge portion of the lever projecting piece 121 of the connecting pin penetrating lever 120 which is directed to the first pivoting direction, the interlocking contacting piece 126 is bent at a right angle toward the unlatching output lever 130, The interlocking contact piece 126 is capable of coming into contact with the side edge of the lever projection 131 of the latch release output lever 130 that is directed in the first rotation direction. Therefore, the latch release output lever 130 receives the biasing force of the torsion coil spring 129 via the connecting pin penetrating lever 120, and is biased in the second rotation direction. And always, when the stopper part 135 with which the tip part of the lever protrusion 132 was equipped contact | abuts with the mechanism board 101 (refer FIG. 5), both the latch release output lever 130 and the connecting pin penetration lever 120 are shown in FIG. It is positioned at the original position.

As shown in FIGS. 5 and 7, the mechanism board 101 is assembled with a locking lever 180 and a locking actuator 185 for moving the connecting pin 400 in the guide long hole 133. The locking lever 180 includes a lever projection 181 (see FIG. 7) extending from the sub support shaft 103 toward the locking actuator 185 and a lever projection 182 extending from the sub support shaft 103 toward the connecting pin 400 (see FIG. 7). And. An arcuate long hole 183 is formed through the lever projection 182 of the locking lever 180. The long hole 183 can be superimposed on the guide long hole 133 and the L-shaped long hole 123, and the connection pin 400 can move through the long hole 183 so as to be movable.

The locking actuator 185 mainly includes an electric motor operated by remote control (the remote control key 301 (see FIG. 1) or the operation of the central door lock button in the vehicle), and the output lever 186 thereof is one lever protrusion of the locking lever 180. It is connected to 181 via a pin and a long hole (see FIG. 7). Further, the output lever 186 and the indoor lock operating unit 16 are connected such that the output lever 186 is pivoted by the movement operation (lock / unlock operation) of the indoor lock operating unit 16 (see FIG. 5).

When the lock / unlock operation of the indoor lock operating portion 16 is performed or the locking actuator 185 is actuated, the locking lever 180 is pivoted around the sub support shaft 103, and the connection pin 400 is the main of the guide long hole 133. It moves between the center end (the position shown in FIG. 7) on the support shaft 102 side and the outer end (the position shown in FIG. 12) of the guide long hole 133 on the L-shaped second side path 123B side.

For example, when the lock operation unit 16 is operated to lock (operation to move the vehicle door 90 in the closing direction), the locking lever 180 pivots around the sub support shaft 103 in the counterclockwise direction in FIG. The lock position of the outer end of the hole 133 is obtained (see FIG. 12). On the other hand, when the indoor lock operating portion 16 is unlocked (operation to move the vehicle door 90 in the opening direction), the locking lever 180 pivots around the sub support shaft 103 clockwise in FIG. It moves to the unlocking position (refer to FIG. 7) of the center side end of the long hole 133.

Here, in the present embodiment, the center side end portion of the portion of the guide long hole 133 which can overlap with the L-shaped first side 123A (the portion overlapping with the rotation region of the center side interference portion 167 described later) This corresponds to the unlock position, and the outer part of the part of the guide long hole 133 which can overlap with the L-shaped second side path 123B (the part overlapping with the pivoting area of the first side projecting piece 163 described later) It corresponds to the "lock position". Further, a portion of the guide long hole 133 which is sandwiched between the unlock position and the lock position corresponds to the "intermediate position" of the present invention, and the "intermediate position" of the portion which can overlap with the L-shaped first side path 123A. Corresponds to the “first intermediate position” in the present invention, and the portion that can overlap with the L-shaped second side path 123B corresponds to the “second intermediate position” in the present invention. Note that FIGS. 12, 19 and 20 show the connecting pins 400 disposed at the lock position, the second intermediate position, and the first intermediate position, respectively. Also, in normal operation, the connecting pin 400 is arranged at either one of the both end portions of the guide long hole 133, that is, either one of the unlocking position or the locking position, and the middle position (first middle position) It does not stop at the position and the second intermediate position).

When the connecting pin 400 is in the unlocking position or the first intermediate position, the uncoupling output lever 130 and the connecting pin penetrating lever 120 are integrally rotatably coupled by the connecting pin 400. That is, power can be transmitted from the connecting pin penetration lever 120 to the latch release output lever 130.

On the other hand, when the connecting pin 400 is at the lock position which is the outer end of the guide long hole 133, the connecting pin 400 can move in the longitudinal direction in the L-shaped second side path 123B while being held at the lock position. . Therefore, even if the connecting pin penetration lever 120 pivots around the main support shaft 102 in the first pivoting direction, the power is not transmitted to the latch release output lever 130, and the latch release output lever 130 is shown in FIG. It will stay in position.

As shown in FIG. 16, the out-of-vehicle handle connecting lever 150 has a pair of

lever protrusions

151 and 152 protruding in opposite directions from the main support shaft 102. One lever protrusion 151 extends from the main support shaft 102 to the opposite side to the in-vehicle handlebar connecting lever 140, and a through hole 153 is formed at the tip end thereof. A slide bush 153B is supported by the through hole 153, and one end of an open cable 94W extended from the outside door handle 17 is connected to the slide bush 153B (see FIG. 5).

Further, from the side edge portion of the lever projecting piece 151 directed in the second rotation direction, the interlocking contact piece 154 is bent at a right angle toward the connecting pin penetrating lever 120 (backward in FIG. 16). It is done. On the other hand, the side edge portion of the lever projecting piece 121 of the connecting pin penetrating lever 120 which is directed to the second rotation direction is directed toward the vehicle outside handle connecting lever 150 (toward the paper surface of FIG. 16). The contact piece 127 is bent at a right angle.

When the outside door handle 17 is opened (pulled to the front), the open cable 94W is pulled toward the outside door handle 17 by the operation power, and the outside handle connection lever 150 rotates around the main support shaft 102 from the original position for the first time. Rotate in the moving direction. At this time, since the interlocking

contact pieces

127 and 154 abut (see FIG. 16), the connecting pin penetration lever 120 is pushed by the outside handle connection lever 150 in the first pivoting direction. That is, regardless of the lock / unlock state of the door lock (the position of the connecting pin 400 in the guide long hole 133), the operating power due to the opening operation of the outside door handle 17 can By being transmitted, they always rotate together in the first rotation direction. Further, as described above, when the connecting pin 400 is in the unlock position, the connecting pin through lever 120 and the latch release output lever 130 are integrally rotatably connected, so the operation power by the open operation of the outside door handle 17 is , And the unlatched output lever 130 via the outside handle connection lever 150 and the connection pin penetration lever 120.

Further, as shown in FIG. 16, the side edge portion of the other lever projection piece 152 of the outside handle connection lever 150 facing the second pivoting direction faces the fully open lock lever 170 (in FIG. The interlocking abutment 155 is bent at a right angle.

When the external handle coupling lever 150 is pivoted in the first pivoting direction by the opening operation of the external door handle 17, the interlocking contact piece 155 pushes the fully open lock lever 170 into pivoting in the first pivoting direction. (See Figure 9).

The “handle interlock lever” according to the present invention is configured by the in-vehicle handle connecting lever 140, the connecting pin penetrating lever 120 and the out-of-vehicle handle connecting lever 150.

Here, remote control device 100 is provided with release actuator 60 (see FIG. 5), and door latch releasing force transmission mechanism 100K receives power of release actuator 60 and rotates main support shaft 102 in the first rotational direction. An actuator interlocking lever 160 that rotates is provided. The release actuator 60 operates when the door latch by the latch mechanism 20K is released by the manual operation of the in-vehicle door handle 18 or the out-vehicle door handle 17. Specifically, for example, it operates as a first operation condition that one of the

switches

110 and 111 is turned on and the door latch of the rear door lock device 10B is released, and the electric door open / close device starts operation (vehicle The latch mechanism 20K is maintained in the door unlatched state until the door 90 starts the motorized slide).

Further, the release actuator 60 operates with the remote operation (the operation of the remote control key 301 and the door opening and closing button in the car) performed as the second operation condition, and rotationally drives the actuator interlocking lever 160 to release the door latch. Do.

As shown in FIG. 17, the actuator interlocking lever 160 extends from the main support shaft 102 to the opposite side of the in-vehicle steering wheel connecting lever 140 (see FIG. 7). The actuator interlocking lever 160 has a central sector 161 close to the main support shaft 102 and a tip end projection 162 projecting from the central sector 161 opposite to the main support shaft 102. The front end side projecting piece 162 is extended from the second rotational direction in the center side sector 161 and is a first side projecting piece 163 that protrudes in the first rotational direction from an intermediate position in the rotational radial direction. And a second side projecting piece 164 projecting in the first rotation direction from the end remote from the main support shaft 102. A through hole 165 is formed at an end of the second side protruding piece 164 on the first rotational direction side. A slide bush 165B is supported in the through hole 165, and one end of an open cable 95W extending from the release actuator 60 is fixed to the slide bush 165B (see FIG. 5). When the release actuator 60 is actuated, the open cable 95 W is pulled toward the release actuator 60 by its power. Thus, the actuator interlocking lever 160 pivots around the main support shaft 102 in the first pivoting direction.

Further, from the side edge portion of the tip end side projecting piece 162 of the actuator interlocking lever 160 which is directed to the second rotation direction, the interlocking abutting piece is directed toward the fully open lock lever 170 (in the direction of the paper surface of FIG. 17). 166 is bent at a right angle, and from the tip of the lever projection 171 of the fully open lock lever 170 (see FIG. 7) to the actuator interlock lever 160 (toward the paper surface of FIG. 7) The contact piece 173 is bent at a right angle. The interlocking

contact pieces

166 and 173 can be in contact with each other.

When the release actuator 60 is actuated, it is pushed by the interlocking contact piece 166 and the fully open lock lever 170 is pivoted in the first pivoting direction. The actuator interlocking lever 160 is biased in the second pivoting direction by a coil spring 176 (see FIG. 5) which biases the fully open lock lever 170 in the second pivoting direction, and a stopper provided on the mechanism board 101 The contact of the actuator interlocking lever 160 with the actuator interlocking lever 104 (see FIG. 5) positions the actuator interlocking lever 160 and the fully open lock lever 170 in the original positions shown in FIGS. 5 and 7. When the fully open lock lever 170 is urged in the second rotation direction by the contact between the interlocking contact piece 155 of the vehicle outside handle connection lever 150 and the fully open lock lever 170 described above, the vehicle outside handle connection lever 150 is also (2) Although it is biased in the pivoting direction, by positioning the fully open lock lever 170 in the original position, the outboard handle connection lever 150 is also positioned in the original position shown in FIGS. 5 and 7.

By the way, as shown in FIG. 17, in the center-side sector 161 of the actuator interlock lever 160, the portion on the first rotation direction side of the tip-side projection piece 162 (hereinafter referred to as the center-side interference portion 167) has a guide length. The contact flat surface 167B, which extends in the radial direction of rotation along one side edge extending in the longitudinal direction of the hole 133 and faces the first rotation direction, is the guide long hole 133 and the L-shaped first side path 123A. It extends in a straight line parallel to one longitudinally extending side.

Further, in the center side interference portion 167, the tip end portion in the rotation radial direction is an arc-shaped member guide portion 167A centering on the main support shaft 102, and the main support shaft 102 in the L-shaped first side path 123A. It is arrange | positioned in the intermediate part of the side edge part and L-type 2nd side path | route 123B. In other words, the member guide portion 167A of the center side interference portion 167 is disposed closer to the main support shaft 102 than the side on the main support shaft 102 side in the L-shaped second side path 123B. The center side end of the guide long hole 133 overlaps the pivoting area of the center side interference part 167, and the middle part and the outer end of the guide long hole 133 are pivoting of the center side interference part 167. It is arranged outside the area. That is, when the connecting pin 400 is positioned at the unlock position, the center side interference portion 167 can press the connecting pin 400 in the first rotation direction by the abutting flat surface 167B, and the connecting pin 400 is not When positioned outside the lock position, it is impossible to push the connecting pin 400 in the first rotation direction.

As shown in FIG. 17, the portion of the first side projection piece 163 on the main support shaft 102 side is an arc-shaped member guide portion 163A centered on the main support shaft 102, and the L-shaped second side path It is disposed between the side on the side of the main support shaft 102 in 123 B and the side on the side away from the main support shaft 102. Also, the contact flat surface 163B of the first side projection piece 163 facing in the first rotational direction extends parallel to one of the guide elongated holes 133 and one side of the L-shaped first side path 123A extending in the longitudinal direction. There is. Then, the outer end of the guide long hole 133 is overlapped with the rotation area of the first side protruding piece 163, and the middle part and the center side end of the guide long hole 133 are the first side protruding piece. It is arranged outside the pivoting area 163. That is, when the connection pin 400 is in the lock position, the first side projection piece 163 can push the connection pin 400 in the first rotation direction by the abutting flat surface 163B, and the connection pin 400 When positioned closer to the center than the lock position, it is impossible to push the connecting pin 400 in the first rotation direction.

As shown in FIG. 19, in the portion sandwiched between the center side interference portion 167 and the first side projecting piece 163, the escape groove 168 (also corresponds to the “blocking portion” of the present invention) of the present invention is formed. It is done. The escape groove 168 opens at a side edge of the actuator interlocking lever 160 facing in the first rotational direction, and extends in an arc toward the second rotational direction. The width of the relief groove 168 is approximately twice the width of the connecting pin 400, whereby the connecting pin 400 can be positioned between the first intermediate position (see FIG. 20) and the second intermediate position (see FIG. 20). It is movable between them (see FIG. 19). Specifically, the end of the escape groove 168 away from the main support shaft 102 (the member guide portion 163A of the first side projection piece 163) and the side of the L-shaped second side path 123B on the main support shaft 102 side The distance between the side and the side is larger than the width of the connection pin 400 (specifically, the width of the second shaft 420 described later), and the connection pin 400 disposed at the second intermediate position is a relief groove. It is movable along the L-shaped second side path 123B in the inside of the line 168. Further, the distance between the end of the escape groove 168 on the main support shaft 102 side (the member guide portion 167A of the center side interference portion 167) and the side of the L-shaped second side path 123B on the main support shaft 102 side is The width of the connecting pin 400 is almost the same.

A detailed configuration of the connecting pin 400 is shown in FIG. 18A. As shown in the figure, the connection pin 400 includes a first shaft portion 410, a non-circular shaft portion 403, and a second shaft portion 420 in this order from one end side in the axial direction. From the boundary with the circular shaft 403 and the boundary between the non-circular shaft 403 and the second shaft 420, the

ridges

401 and 401 project laterally.

The non-circular shaft portion 403 is disposed in the guide long hole 133, and its cross-sectional shape is an oval having a two-face width substantially the same as the width of the guide long hole 133, as shown in FIG. 18B. . Specifically, the arc surfaces 403A and 403A at both ends in the longitudinal direction are connected by a pair of

flat surfaces

403B and 403B parallel to each other, and the pair of

flat surfaces

403B and 403B have the width of the guide elongated hole 133. The connecting pin 400 is prevented from rotating with respect to the guide long hole 133 in opposition to the direction (longitudinally extending) both

inner side surfaces

133A and 133A (see FIG. 17). In addition, the pair of

flanges

401 and 401 sandwich the lever projecting piece 131 in the thickness direction, so that the movement of the connection pin 400 in the axial direction is prohibited.

The first shaft portion 410 protrudes from the lever protrusion 131 of the latch release output lever 130 toward the mechanism board 101 side (the back side in FIG. 5 and FIG. 7). The base end of the first shaft portion 410 is a square portion 411 having a rectangular cross section (specifically, a square cross section). The square portion 411 is movably fitted in an L-shaped elongated hole 123 which penetrates the lever protrusion 121 of the connecting pin penetration lever 120.

On the other hand, the tip of the first shaft portion 410 is a cylindrical portion 412 having a circular cross section. The cylindrical portion 412 is movably fitted in an elongated hole 183 (see FIGS. 7 and 12) which passes through the lever projection 182 of the locking lever 180.

The second shaft portion 420 of the connecting pin 400 protrudes from the lever protrusion 131 of the latch release output lever 130 toward the opposite side to the first shaft portion 410 (the front side in FIG. 5 and FIG. 7). The second shaft portion 420 has a prismatic shape with a rectangular cross section (specifically, a cross section square), and the side surface of the second shaft portion 420 is formed of four flat surfaces parallel to the axial direction of the connecting pin 400. (See FIG. 17). Of these four flat surfaces, two flat surfaces parallel to each other face in the radial direction of rotation about the main support shaft 102 (longitudinal direction of the guide elongated hole 133), and the remaining two flat surfaces are It faces the first rotation direction and the second rotation direction around the main support shaft 102.

Then, as shown in FIG. 17, when the connecting pin 400 is at the unlock position, one of the four flat surfaces constituting the side surface of the second shaft 420 is one flat surface facing the second rotation direction. It is possible to make surface contact with the contact flat surface 163B of the first side projection piece 163 (hereinafter referred to as “contact flat surface 421” as appropriate). Further, when the connecting pin 400 is located at the lock position, the flat contact surface 421 of the second shaft 420 can be in surface contact with the flat contact surface 167B of the center side interference part 167. .

The configuration of the present embodiment is as described above, and next, the operation of the door latch release force transmission mechanism 100K will be described. When the vehicle door 90 is fully opened, the in-vehicle door handle 18 is closed (tilted in the closing direction), the fully open lock lever 170 is pushed by the rod 105 and the first pivoting direction (about the main support shaft 102) (Clockwise direction in FIG. 7). Then, the open cable 93W connected to the fully open lock lever 170 is pulled toward the remote control device 100, and the fully open holding of the vehicle door 90 by the latch mechanism 20K of the fully open door lock device 10C is released. Thus, the vehicle door 90 can be electrically or manually slid in the closing direction from the fully open state.

Also, when the vehicle door 90 is fully open and the outside door handle 17 is closed (pulled to the front), it is pulled by the open cable 94W and the outside handle connection lever 150 is rotated in the first rotation direction. When pushed by the outside handle connection lever 150, the connection pin penetration lever 120 and the fully open lock lever 170 integrally rotate around the main support shaft 102 in the first rotation direction (see FIG. 9). When the fully open lock lever 170 pivots in the first rotation direction, the open cable 93W is pulled toward the remote control device 100, and the fully open holding of the vehicle door 90 by the fully open door lock device 10C is released. Thus, the vehicle door 90 can be electrically or manually slid in the closing direction from the fully open state.

Further, when the vehicle door 90 is fully open, remote control is performed without operating the in-vehicle door handle 18 or the out-vehicle door handle 17 (when the remote control key 301 or the in-vehicle door open / close button is operated). Thus, the release actuator 60 operates to rotationally drive the actuator interlocking lever 160 in the first pivoting direction, and the actuator interlocking lever 160 is pushed by the actuator interlocking lever 160 to integrally rotate the fully open lock lever 170 in the first pivoting direction. Then, the open cable 93W is pulled toward the remote control device 100, and the fully open holding of the vehicle door 90 by the fully open door lock device 10C is released. This makes it possible to electrically slide the vehicle door 90 in the closing direction.

Next, the operation of the door latch release force transmission mechanism 100K when the operation is performed to open the vehicle door 90 in the closed holding state, the child lock is in the "unlocked state" (the position where the child lock pin 125 is shown by the solid line in FIG. 7). It explains on the premise that it is).

When the door lock is in the “unlocked state” (the unlock position where the connecting pin 400 is shown by the solid line in FIG. 7) and the in-vehicle door handle 18 is opened, as shown in FIG. 7 to FIG. When the lever 140 pivots around the main support shaft 102 in the first pivoting direction and pushes the child lock pin 125, the connecting pin penetration lever 120 pivots in the first pivoting direction. The rotation of the connecting pin penetration lever 120 is transmitted to the latch release output lever 130 via the connection pin 400, and the

open cables

91W and 92W are remote control devices 100 by the latch release output lever 130 rotating in the first rotation direction. Pulled to the side. When the latch release output lever 130 reaches near the rotation end position away from the original position in the first rotation direction, the door latch by the respective latch mechanisms 20K of the front door lock device 10A and the rear door lock device 10B is released. (See FIG. 3), the first operating condition of the release actuator 60 described above is satisfied.

Then, the actuator interlocking lever 160 is rotationally driven in the first rotation direction by the release actuator 60, and the center side interference portion 167 (contact flat surface 167 B) abuts on the connection pin 400. That is, by the power of the release actuator 60, the actuator interlocking lever 160, the latch release output lever 130 and the connecting pin penetration lever 120 are held at the rotation end position separated from the original position in the first rotation direction. As a result, even if the in-vehicle handle connection lever 140 returns to the original position after the hand is removed from the in-vehicle door handle 18, the latch mechanism 20K is used until the electric door opening / closing device starts to operate (the vehicle door 90 starts the electric slide). Door latch release can be maintained (see FIG. 10).

When the door lock is in the "unlocked state" and the outside door handle 17 is operated to be opened (pulled to the front), as shown in the change from FIG. 7 to FIG. It turns in the first turning direction. At this time, the outside handle connection lever 150 pushes the connection pin penetration lever 120. Further, since the connecting pin through lever 120 and the latch release output lever 130 are connected by the connecting pin 400, the operation power by the opening operation of the outside door handle 17 is the outside handle handle connecting lever 150 and the connecting pin through lever 120. This is transmitted to the latch release output lever 130, and these integrally rotate around the main support shaft 102 in the first rotation direction. The

open cables

91W and 92W are pulled toward the remote control device 100 by turning the latch release output lever 130 in the first rotation direction. When the latch release output lever 130 reaches near the rotation end position away from the original position in the first rotation direction, the door latch by the respective latch mechanisms 20K of the front door lock device 10A and the rear door lock device 10B is released. The first operating condition of the release actuator 60 is established (see FIG. 3).

Then, the center side interference part 167 (contact flat surface 167B) of the actuator interlocking lever 160 is pressed against the connecting pin 400 by the power of the release actuator 60, and the actuator interlocking lever 160, the latch release output lever 130 and the connecting pin penetrating lever 120 Is held at a rotational end position separated from the original position in the first rotational direction. As a result, even if the hand is released from the outside door handle 17 and the outside handle connecting lever 150 returns to the original position (see FIG. 10), the electric door opening / closing device starts to operate (the vehicle door 90 starts electric sliding) Can maintain the door latch release by the latch mechanism 20K.

When the door lock is in the "unlocked state" and remote control is performed without opening the in-vehicle door handle 18 or the out-vehicle door handle 17, the second operation condition of the release actuator 60 described above is satisfied. As shown in the change from FIG. 7 to FIG. 10, the actuator interlocking lever 160 pivots around the main support shaft 102 in the first pivoting direction, and the center side interference part 167 pushes the connecting pin 400 to latch it. The release output lever 130 pivots in the first pivoting direction. Then, as described above, the door latch is released by the latch mechanisms 20K provided in the front door lock device 10A and the rear door lock device 10B. Then, the power of the release actuator 60 can maintain the door latch release of the latch mechanism 20K until the operation of the electric door opening / closing device starts (the vehicle door 90 starts the electric slide). In addition, the center side interference part 167 of the actuator interlocking lever 160 corresponds to the "1st contact part" of this invention.

That is, when the door lock and the child lock are both in the "unlocked state", the vehicle door 90 is opened by the opening operation of the in-vehicle door handle 18, the opening operation of the outside door handle 17, and the remote control such as the remote control key 301. Is possible.

When the door lock is in the “locked state” (the locked position where the connecting pin 400 is shown by the solid line in FIG. 12) and the door handle 18 is opened, as shown in FIG. 12 to FIG. The handle connecting lever 140 and the connecting pin penetrating lever 120 are pivoted in the first rotation direction, but the connecting pin 400 moves in the L-shaped second side path 123B while being held at the lock position of the guide long hole 133 Therefore, the transmission of power from the coupling pin through lever 120 to the latch release output lever 130 is interrupted. That is, since the operation power by the opening operation of the in-vehicle door handle 18 is not transmitted to the latch release output lever 130, the latch release output lever 130 remains at the original position shown in FIG. Thus, the closing and holding of the vehicle door 90 by the front door lock device 10A and the rear door lock device 10B is maintained.

When the door lock is in the “locked state” and the door handle 17 is opened, as shown in the change from FIG. 12 to FIG. When pressed by the handle connecting lever 150, the connecting pin penetrating lever 120 integrally rotates in the first rotation direction. However, at this time, since the connection pin 400 moves in the L-shaped second side path 123B, the transmission of power from the connection pin penetration lever 120 to the latch release output lever 130 is interrupted. That is, since the operation power due to the opening operation of the outside door handle 17 is not transmitted to the latch release output lever 130, the latch release output lever 130 remains at the original position shown in FIG. Thus, the closing and holding of the vehicle door 90 by the front door lock device 10A and the rear door lock device 10B is maintained.

When the door lock is in the “locked state” and the remote control is performed without performing the opening operation of the in-vehicle door handle 18 or the out-vehicle door handle 17, the second operation condition of the release actuator 60 described above is satisfied. As shown in the change from FIG. 12 to FIG. 15, the actuator interlocking lever 160 pivots around the main support shaft 102 in the first pivoting direction, and the first side projecting piece 163 pushes the connecting pin 400, The latch release output lever 130 pivots in the first pivoting direction. And the door latch by each latch mechanism 20K with which front side door lock device 10A and rear side door lock device 10B were equipped is released. The first side projection piece 163 of the actuator interlocking lever 160 corresponds to the "second contact portion".

As described above, in the door latch release force transmission mechanism 100K, when the door lock is in the “locked state”, the vehicle door 90 can not be opened even if the outside door handle 17 and the in-vehicle door handle 18 are opened. It is possible to open the vehicle door 90 by remote control of the remote control key 301 or the like.

Summarizing the above, in the door latch release force transmission mechanism 100K, when the outside door handle 17 and the inside door handle 18 are opened, the front door lock device 10A and the rear door are in the “unlocked state” when the door lock is in the “unlocked state”. The closed hold of the vehicle door 90 by the side door lock device 10B can be released, and when the door lock is in the “locked state”, the closed hold can not be released. Further, when remote control of the remote control key 301 or the like is performed, the front door lock device 10A and the rear door lock device 10B are used regardless of whether the door lock is in the “locked state” or the “unlocked state”. The closed holding of the vehicle door 90 can be released.

When the child lock is in the “locked state” (the position where the child lock pin 125 is shown by the two-dot chain line in FIG. 7), when the in-vehicle door handle 18 is opened, the in-vehicle handle connection lever 140 is Although pivoted in the moving direction, the child lock pin 125 is disposed at the child lock position and does not abut on the in-vehicle handle connecting lever 140, so that the operating power is not transmitted to the connecting pin penetrating lever 120 and the latch release output lever 130. Therefore, the connecting pin penetration lever 120 and the latch release output lever 130 remain at the original position shown in FIG. 7 and the front door lock device regardless of whether the door lock is in the “locked state” or the “unlocked state”. The closed retention of the vehicle door 90 by 10A and the rear door lock device 10B is maintained. The “locked state” of the child lock is effective only for the opening operation of the in-vehicle door handle 18, and the door lock is the “unlocked state” even if the child lock is in the “locked state”. The vehicle door 90 can be opened by the opening operation 17.

Now, as shown in FIGS. 10 and 15, the actuator interlocking lever 160 and the latch release output lever 130 have reached the rotational end position separated from the original position in the first rotational direction (or, first from the original position) When the actuator interlocking lever 160 and the latch release output lever 130 stop moving due to, for example, a failure of the release actuator 60, an abnormality of the power transmission path, or the like during rotation in the moving direction) It does not return from the state (that is, the position where the ratchet 30 is shown by the alternate long and two short dashes line in FIG. 4) in which the closing and holding of the lens is released.

In such an emergency, the indoor lock operation unit 16 (see FIG. 6) may be operated. Specifically, when an abnormality occurs with the door lock in the "unlocked state", the lock operation (operation to move the vehicle door 90 in the closing direction) is performed, and when an abnormality occurs with the door lock in the "locked state" The lock operation (operation of moving the vehicle door 90 in the closing direction) is performed.

When the door lock is in the “unlocked state” and the locking operation is performed, the connecting pin 400 moves from the unlocked position to the intermediate position and the pivoting of the center side interference portion 167 as shown in the changes in FIGS. The actuator interlocking lever 160 is disposed outside the area, and the actuator interlocking lever 160 is separated from the coupling pin penetration lever 120 and the latch release output lever 130 (the release actuator 60 is separated from the latch mechanism 20K). At the same time, the connection pin 400 enters into the escape groove 168 by the biasing force of the torsion coil spring 129, and the connection pin penetrating lever 120 and the latch release output lever 130 integrally rotate in the second pivoting direction to the original position. To return. As a result, the

open cables

91W and 92W are returned to the latch mechanism 20K side provided in the front door lock device 10A and the rear door lock device 10B, and the latch mechanisms 20K are restored to the state where the vehicle door 90 can be closed and held. It can be done. In detail, the connecting pin 400 moving from the unlock position to the intermediate position abuts on the first side protruding side 163 of the actuator interlocking lever 160 and is held at the second intermediate position, and the member guide portion 163A It moves along the relief groove 168.

When the door lock is in the “locked state” and the unlocking operation is performed, as shown in the changes in FIG. 15 to FIG. 20, the connection pin 400 moves from the lock position to the intermediate position and the first side projection piece The actuator interlocking lever 160 is disposed out of the pivoting region of 163 and is separated from the coupling pin penetration lever 120 and the latch release output lever 130 (the release actuator 60 is separated from the latch mechanism 20K). Then, the connecting pin 400 enters the relief groove 168 by the biasing force of the torsion coil spring 129, and the connecting pin penetrating lever 120 and the latch release output lever 130 integrally rotate in the second rotation direction and return to the original position Do.

As described above, in the door latch release force transmission mechanism 100K, even when the door lock is in the “locked state” or the “unlocked state”, the actuator interlocking lever 160 does not move due to the failure of the release actuator 60 or the like. The release actuator 60 can be disconnected from the latch mechanism 20K to return the vehicle door 90 to a state capable of closing and holding.

Further, when the vehicle door 90 closed and held by the above-described actuator separation operation (lock / unlock operation by the indoor lock operation unit 16) is opened, the indoor lock operation unit 16 may perform the unlock operation. In detail, when the actuator separation operation is performed, the center side interference portion 167 of the actuator interlocking lever 160 overlaps the center side end (unlock position) of the guide long hole 133 as shown in FIG. When the unlocking operation of the indoor lock operating portion 16 is performed in this state, as shown in the change from FIG. 19 to FIG. 20, the connection pin 400 moves in the escape groove 168 from the second intermediate position to the center side. It abuts on the member guide portion 167A of the center side interference portion 167 and is held at the first intermediate position. In this state, since the connecting pin 400 is located in the L-shaped first side path 123A, power can be transmitted from the connecting pin through lever 120 to the latch release output lever 130. On the other hand, since the connecting pin 400 is disposed outside the pivoting area of the center side interference part 167, the actuator interlocking lever 160 is separated from the connecting pin penetrating lever 120 and the latch release output lever 130 (release actuator 60 is in a state of being separated from the latch mechanism 20K).

When the lock operation is performed by the indoor lock operation unit 16 after the actuator release operation (lock / unlock operation by the indoor lock operation unit 16), the connecting pin 400 is disposed at the second intermediate position, and the in-vehicle door handle The door 18 and the outside door handle 17 lock the vehicle door 90 so that it can not be released.

A portion of the side edge of the L-shaped first side path 123A of the connecting pin penetrating lever 120 facing the first pivoting direction that overlaps the pivoting area of the center side interference portion 167 of the actuator interlocking lever 160 (ie, The portion in contact with the connecting pin 400 in the unlocked position is the third contact edge portion 123T1 corresponding to the "third contact portion" of the present invention, and is outside the pivoting region of the center side interference portion 167 (Ie, the portion in contact with the connection pin 400 in the first intermediate position) is the fourth contact edge 123T2 corresponding to the "fourth contact portion" of the present invention (Figs. 19 and 20). reference).

Then, when the external door handle 17 is opened in a state where the connecting pin 400 is disposed at the first intermediate position, the actuator that has abnormally stopped because the connecting pin 400 passes outside the member guide part 167A of the center side interference part 167. While the interlock lever 160 (release actuator 60) is separated from the latch mechanism 20K, the outboard handle connection lever 150, the connection pin penetration lever 120 and the latch release output lever 130 integrally rotate in the first rotation direction, and the

open cables

91W and 92W Is pulled to the remote control device 100 side. As a result, the closing retention of the vehicle door 90 by the latch mechanism 20K of the front door lock device 10A and the rear door lock device 10B is released, and the vehicle door 90 can be opened manually. Since the lock state of the child lock is invalid with respect to the opening operation of the outside door handle 17, the vehicle door is opened by the opening operation of the outside door handle 17, regardless of whether the child lock is in the locked state or the unlocked state. The vehicle door 90 can be opened by releasing the closing hold of 90. Also, if the child lock is in the unlocked state, it becomes possible to open the vehicle door 90 by the opening operation of the in-vehicle door handle 18 as in the case of the outside door handle 17.

The above is the description regarding the operation of the door latch release force transmission mechanism 100K. Thus, in the door latch release force transmission mechanism 100K, in the unlocked state in which the connecting pin 400 is disposed at the unlock position, the operation of the door handle (the in-vehicle door handle 18, the out-vehicle door handle 17) or the switch operation of the release actuator 60 In any one operation of the latch mechanism 20K, the latch of the vehicle door 90 is released. On the other hand, when using the door handle in the locked state where the connecting pin 400 is disposed in the locked position, the unlocking operation of moving the connecting pin 400 to the unlocked position, the door handle (in-vehicle door handle 18, outside door handle The latch 20 of the vehicle door 90 by the latch mechanism 20K is released by two operations of the operation 17). On the other hand, when the release actuator 60 is used in the locked state, the above unlocking operation becomes unnecessary, and the latch 20 of the vehicle door 90 by the latch mechanism 20K is only required by one operation of the switch of the release actuator 60. It is released. That is, when using the release actuator 60, the operation for releasing the latch 20 of the vehicle door 90 by the latch mechanism 20K is the release actuator regardless of whether the door lock is in the unlocked state or in the locked state. Only one operation of the 60 switch operations is required, and the convenience is improved compared to the prior art.

Further, in the door latch release force transmission mechanism 100K, the center side interference portion 167 in contact with the connecting pin 400 in the unlocked position of the actuator interlocking lever 160 and the first side projecting piece 163 in contact with the connecting pin 400 in the locked position. The release actuator 60 pivots the latch release output lever 130, and the release actuator 60 fails and does not move when the latch mechanism 20K is unlatched. In the case where the connection pin 400 is disposed at an intermediate position between the lock position and the unlock position and received in the release groove 168, the latch release output lever 130 and the latch mechanism 20K are separated from the release actuator 60 90 can be closed back to a latchable state.

In addition, the escape groove 168 has a width such that the connection pin 400 can move to the first intermediate position and the second intermediate position in the inside, and the connection pin penetrating lever 120 abuts on the connection pin 400 in the unlocked position. Since the fourth contact edge which contacts the connection pin 400 at the first intermediate position without contacting the connection pin 400 at the second intermediate position is provided separately from the third contact edge, the connection pin 400 is provided. Is received in the release groove 168 and the latch release output lever 130 and the latch mechanism 20K are separated from the release actuator 60 to latch the vehicle door 90 in the closed state, and then the connecting pin 400 is disposed at the first intermediate position. The latch 20 of the vehicle door 90 can be released by the door handle 18 or the outside door handle 17, and the connecting pin 400 is disposed at the second intermediate position. In, can be locked unable to release the latch 20 of the vehicle door 90 by the vehicle door handle 18 and the exterior door handle 17.

In the present embodiment, when the vehicle door 90 closed by the actuator release operation or the actuator release operation is opened, the operation in the case of operating the indoor lock operation unit 16 is exemplified. However, the remote control key 301 is operated. Even when the key 303 (see FIG. 1) is inserted into the key cylinder 302 provided on the outer surface of the vehicle door 90 and the lock / unlock operation is performed, the remote control device 100 is operated as in the case of operating the indoor lock operation unit 16. Can operate. That is, the remote control key 301 and the key cylinder 302 are also included in the "lock switching means" of the present invention. Further, as described above, also by operating the locking actuator 185, the remote control device 100 can be operated in the same manner as when the indoor lock operating unit 16 is operated. Summarizing the above, at least one of the indoor lock operating unit 16, the remote control key 301, the key cylinder 302, and the locking actuator 185 is the "lock switching means" of the present invention.
