Description

  The present invention relates to a door latch release force transmission mechanism that can release a latch by transmitting a door latch release force from a door handle provided on the vehicle door to a latch mechanism that can latch a vehicle door in a closed state.

  In recent years, door latch release force transmission mechanisms that can transmit not only door handles but also door latch release forces from release actuators to latch mechanisms have become widespread (see, for example, cited document 1). As one of the door latch release force transmission mechanisms of this type, the intermediate second rotation of the first, second, and third rotation levers that sequentially transmit and rotate 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 last third rotating lever. In addition, the relay member is assembled to the third rotating lever so as to be movable between the lock position and the unlock position, and the second rotation is performed only when the relay member is disposed at the unlock position. When the door latch releasing force can be transmitted from the moving lever to the third rotating lever, and the relay member is disposed at the lock position, the second latching lever and the third rotating lever are disconnected from each other, and the door latch The release force is not transmitted, and the door cannot be opened by the door handle and the release actuator.

By the way, vehicles with a release actuator are rapidly spreading due to the convenience that the vehicle door can be easily opened even when a load is held. However, when the conventional door latch release force transmission mechanism is locked, not only the door handle and the latch mechanism, but also the release actuator and the latch mechanism are blocked. When the release actuator is used, the unlocking operation must be performed in advance as in the case of using the door handle. That is, the conventional door latch release force transmission mechanism requires two operations, that is, a lock release operation and a release actuator switch operation when riding in a locked vehicle, and is convenient for using the release actuator. There was a problem that the property was halved.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a door latch release force transmission mechanism that is more convenient than conventional ones.

In order to achieve the above object, the door latch release force transmission mechanism according to the invention of claim 1 is provided with a door handle and a release actuator provided in the vehicle door in contrast to a latch mechanism configured to be able to latch the vehicle door in a closed state. It is configured to carry door latch release force from the latch mechanism to a latch releasable door latch release force transmission mechanism is configured to rotate only in the door latch release force from the door handle of the door handle and release the actuator a handle interlocking lever that, an actuator interlocking lever configured to rotate only in the door latch release force from a release actuator of the door handle and release the actuator, the door latch release force, by receiving from the handle interlocking lever and the actuator interlock lever latch Output to mechanism A latch release output lever configured ability receives locking switching power from the lock switching means provided in the vehicle door, it is arranged to reciprocate between a locked position and an unlocked position of the latch release output lever, Ann When placed in the locked position, it is located in the rotation region of both the handle interlocking lever and the actuator interlocking lever, and transmits the door latch release force from any one of the handle interlocking lever and the actuator interlocking lever to the latch release output lever. as configured Meanwhile, when placed in the locking position is positioned only in the pivoting region of the actuator interlock lever out from the pivot region of the handle interlocking lever, only the door latch release force from the actuator interlocking lever unlatching output When configured relay member to transmit to the lever, actuated A first contact portion that is provided on the interlocking lever and abuts against the relay member at the unlocked position to apply a door latch release force to the relay member; and a door latch that contacts the relay member disposed at the lock position of the actuator interlocking lever. Provided between the second contact portion for applying the release force to the relay member and the first and second contact portions of the actuator interlocking lever, and disposed at an intermediate position between the lock position and the unlock position. And a blocking portion for receiving the relay member and blocking the door latch releasing force from the actuator interlocking lever to the latch releasing output lever .

According to a second aspect of the present invention, in the door latch release force transmission mechanism according to the first aspect, a handle interlocking lever, an actuator interlocking lever, a latch release output lever, and a latch release output lever, which are overlapped with each other and are arranged coaxially. The relay member assembled to the release output lever, and the latch release output lever extending in the rotational radius direction, movably receiving the relay member, and having one end region on the rotary shaft side as an unlock position, the other end A guide slot with the region as a lock position and an opening between the first and second contact portions and extending in a direction crossing the rotational radius direction of the actuator interlocking lever, between the lock position and the unlock position. An escape groove as a blocking portion that receives the relay member arranged at the intermediate position and blocks the door latch release force from the actuator interlocking lever to the latch release output lever; It has a feature where you have.

A third aspect of the present invention, the door latch release force transmission mechanism according to claim 2, the relay member at an inner portion relief movable in a first intermediate position of the rotation shaft side and a second intermediate position on the opposite side A groove, a third contact portion that is provided in the handle interlocking lever and contacts the relay member in the unlocked position to apply a door latch release force to the relay member; and a second intermediate position in the escape groove of the handle interlocking lever. It can contact the relay member located at the first intermediate position in the escape groove without contacting the relay member located, and the door latch release force can be transmitted from the handle interlocking lever to the latch release output lever via the relay member. characterized in place with a fourth contact portion to.

A fourth aspect of the present invention, the door latch release force transmission mechanism according to claim 2 or 3, and the connecting pin as a relay member inserted through the guide slot, provided on the side surfaces of the actuator interlocking lever of the connecting pin has a feature where having a contact flat surface capable impart door latch release force to unlatch the output lever from the actuator interlock lever in contact with each other when the relay member is unlock position or the lock position.

According to a fifth aspect of the present invention, in the door latch release force transmission mechanism according to the fourth aspect of the present invention, the connecting pin is provided in a portion disposed in the guide elongated hole and is opposed to a pair of inner side surfaces of the guide elongated hole. And having a pair of flat surfaces for preventing the connection pins from rotating.

  The door latch release force transmission mechanism of claim 1 includes a handle interlocking lever, an actuator interlocking lever, and a latch release output lever, and the handle interlocking lever rotates only by the door latch releasing force from the door handle, and is interlocked with the actuator. The lever rotates only with the door latch release force from the release actuator. When the relay member is disposed at the unlocked position, the latch release output lever rotates by any door latch release force of the handle interlocking lever or the actuator interlocking 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 unlock position, the latch of the vehicle door by the latch mechanism is released by any one of the door handle operation or the release actuator switch operation. On the other hand, when the relay member assembled to the latch release output lever is arranged at the lock position, the latch release output lever rotates only with the door latch release force from the actuator interlocking lever and outputs the door latch release force to the latch mechanism. . That is, when the door handle is used in the locked state where the relay member is disposed at the lock position, the latch mechanism is used in two operations, that is, the unlock operation for moving the relay member to the unlock position and the door handle operation. The vehicle door latch is released. On the other hand, when the release actuator is used in the locked state, the above-described unlocking operation becomes unnecessary, and the latch of the vehicle door by the latch mechanism is released by only one operation of the release actuator switch operation. In other words, when using a release actuator, regardless of the unlocked and locked states, only one release actuator switch operation is required to unlock the door by the latch mechanism, which is more convenient than before. Will improve.

By the way, if the release actuator turns the latch release output lever and the release actuator fails to move at the position where the latch mechanism releases the latch, if the vehicle door cannot be closed and returned to the latchable state, It becomes impossible to drive the vehicle. In contrast, in the door latch release force transmission mechanism according to claim 1, a first contact portion for contacting the connection member in the unlocked position of the actuator interlocking lever, the second abutment portion abutting on the relay member locked position In the middle, there is a blocking part that receives the relay member and blocks the door latch release force from the actuator interlocking lever to the latch release output lever, so the release actuator rotates the latch release output lever and the latch mechanism releases the latch When the release actuator fails and does not move at the position, the relay release member is placed at an intermediate position between the locked position and the unlocked position and received by the blocking portion, thereby releasing the latch release output lever and the 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 release force transmission mechanism according to claim 2 , the relay member moves in the rotational radius direction of the actuator interlocking lever, and the blocking portion opens between the first and second contact portions, so that the pivot radius of the actuator interlocking lever is reached. Since the release groove extends in a direction that intersects the direction, if the latch release output lever and the latch mechanism are disconnected from the release actuator, the latch can be released by the release actuator after the vehicle door is latched to the closed state. Disappear. Further, since the relay member is received in the escape groove, the relay member cannot be disposed at the unlock position. On the other hand, in the door latch release force transmission mechanism according to claim 3 , the escape groove has a width within which the relay member can move to the first intermediate position on the rotating shaft side and the second intermediate position on the opposite side. In addition to the third contact portion that contacts the relay member in the unlock position, the handle interlocking lever does not contact the relay member in the second intermediate position, but contacts the relay member in the first intermediate position. Since the fourth contact portion is provided, the relay member is received in the escape 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, and then the relay member is moved to the first intermediate position. 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.

According to the fourth aspect of the present invention, the contact flat surfaces provided on the side surface of the coupling pin and the side surface of the actuator interlocking lever are in surface contact with each other to transmit the door latch release force. Stabilize. According to the fifth aspect of the present invention , since the connecting pin is prevented from rotating in the guide elongated hole, the contact flat surfaces of the connecting pin and the actuator interlocking lever can be reliably brought into surface contact.

  As shown in FIG. 11, the latch release output lever 130 is provided with a pair of lever protrusions 131 and 132 protruding in the opposite direction from the main support shaft 102. Of the pair of lever protrusions 131 and 132, the front end of the lever protrusion 132 protruding to the same side as the in-vehicle handle connecting lever 140 is connected to the front door lock device 10A and the rear door via open cables 91W and 92W. Each ratchet 30 of the locking device 10B is connected (see FIG. 5).

  Of the latch release output lever 130, a lever protrusion 131 that is superimposed on the lever protrusion 121 of the connecting pin penetrating lever 120 is formed with a guide long hole 133 that extends in the rotational radius direction. The guide elongated hole 133 can be overlapped with the L-shaped first side path 123A of the coupling pin penetrating lever 120 when both the latch release output lever 130 and the coupling pin penetrating lever 120 are in their original positions. A common connecting pin 400 passes through 133 and the L-shaped long hole 123. The connecting pin 400 is supported by a pair of side sides extending in the longitudinal direction of the guide long hole 133 and can reciprocate within the guide long hole 133. The connecting pin 400 corresponds to the “relay member” of the present invention.

  Here, the interlocking contact piece 126 is bent and raised at a right angle from the side edge portion of the lever protruding piece 121 of the connecting pin penetrating lever 120 facing the first rotation direction toward the latch release output lever 130. The interlocking abutting piece 126 can abut on a side edge portion of the lever protruding piece 131 of the latch release output lever 130 facing 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. Then, always, the stopper 135 provided at the tip of the lever protrusion 132 comes into contact with the mechanism panel 101 (see FIG. 5), so that the latch release output lever 130 and the connecting pin penetrating lever 120 are both shown in FIG. It is positioned in 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 protrusion 181 (see FIG. 7) extending from the sub-support shaft 103 toward the locking actuator 185, and a lever protrusion 182 (see FIG. 7) extending from the sub-support shaft 103 toward the connecting pin 400. ). An arc-shaped long hole 183 is formed through the lever protrusion 182 of the locking lever 180. The long hole 183 can be overlapped with the guide long hole 133 and the L-shaped long hole 123, and the connecting pin 400 is movable through the long hole 183.

  The locking actuator 185 is mainly composed of an electric motor that is operated by remote operation (operation of a remote control key or a central door lock button in the vehicle), and its output lever 186 has a pin and a long hole in one lever protruding piece 181 in the locking lever 180. (See FIG. 7). Further, the output lever 186 and the indoor lock operation unit 16 are connected so that the output lever 186 is rotated by a movement operation (lock / unlock operation) of the indoor lock operation unit 16 (see FIG. 5).

  When the locking / unlocking operation of the indoor lock operation unit 16 is performed or the locking actuator 185 is actuated, the locking lever 180 rotates around the sub support shaft 103, and the connecting pin 400 is connected to the main guide hole 133. It moves between the center side end portion (position shown in FIG. 7) on the support shaft 102 side and the outer end portion (position shown in FIG. 12) on the L-type second side path 123 </ b> B side of the guide long hole 133.

  For example, when the indoor lock operation unit 16 is locked (moving in the closing direction of the vehicle door 90), the locking lever 180 rotates about the sub-support shaft 103 in the counterclockwise direction in FIG. It becomes the lock position of the outer side edge part of the hole 133 (refer FIG. 12). On the other hand, when the indoor lock operation unit 16 is unlocked (moving in the opening direction of the vehicle door 90), the locking lever 180 rotates about the sub-support shaft 103 in the clockwise direction in FIG. It moves to the unlock position (see FIG. 7) at the center side end of the long hole 133.

Here, in the present embodiment, the center side end portion of the guide elongated hole 133 that can overlap with the L-shaped first side 123A (the portion that overlaps the rotation region of the center side interference portion 167 described later) of the present invention is “ Corresponding to the “unlock position”, the outer portion of the guide elongated hole 133 that can overlap with the L-shaped second side path 123B (the portion that overlaps the rotation region of the first side protruding piece 163 to be described later) of the present invention. Corresponds to “lock position”. Further, a portion of the guide long hole 133 sandwiched between the unlock position and the lock position corresponds to an “intermediate position” of the present invention, and a portion of the “intermediate position” that can overlap with the L-shaped first side path 123A. Corresponds to the “first intermediate position” of the present invention, and the portion that can overlap the L-shaped second side path 123B corresponds to the “second intermediate position” of the present invention. 12, 19, and 20 show the connecting pins 400 disposed at the lock position, the second intermediate position, and the first intermediate position, respectively. Further, in a normal state, the connecting pin 400 is arranged at either one of the both ends of the guide long hole 133, that is, at either the unlock position or the lock position. The position and the second intermediate position are not stopped.

  When the connecting pin 400 is set to the unlocked position or the first intermediate position, the latch releasing output lever 130 and the connecting pin penetrating lever 120 are connected by the connecting pin 400 so as to be integrally rotatable. That is, power can be transmitted from the connecting pin penetrating lever 120 to the latch release output lever 130.

  On the other hand, when the connecting pin 400 is in the locked position that 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 in the locked position. . Therefore, even if the connecting pin penetrating lever 120 rotates around the main support shaft 102 in the first rotation direction, the power is not transmitted to the latch release output lever 130, and the latch release output lever 130 is not shown in FIG. Will stay in position.

  As shown in FIG. 16, the vehicle exterior handle connecting lever 150 has a pair of lever projecting pieces 151 and 152 projecting in the opposite direction from the main support shaft 102. One lever projecting piece 151 extends from the main support shaft 102 to the side opposite to the in-vehicle handle connecting lever 140, and a through hole 153 is formed at the tip thereof. A slide bush 153B is supported in the through hole 153, and one end of an open cable 94W extending from the exterior door handle 17 is connected to the slide bush 153B (see FIG. 5).

  In addition, the interlocking contact piece 154 is bent at a right angle from the side edge portion of the lever protruding piece 151 facing the second rotation direction toward the connecting pin penetrating lever 120 (toward the back side of the paper surface of FIG. 16). Has been. On the other hand, from the side edge portion of the lever protruding piece 121 of the connecting pin penetrating lever 120 facing the second rotation direction toward the vehicle exterior handle connecting lever 150 (toward the front side of the page in FIG. 16), The contact piece 127 is bent up at a right angle.

  When the outside door handle 17 is opened (pulled forward), the open cable 94W is pulled toward the outside door handle 17 by the operating power, and the outside handle connecting lever 150 is moved around the main support shaft 102 from the original position for the first time. It rotates in the moving direction. At this time, the interlocking contact pieces 127 and 154 are in contact with each other (see FIG. 16), so that the connection pin penetrating lever 120 is pushed in the first rotation direction by the vehicle exterior handle connection lever 150. That is, the operation power generated by the opening operation of the vehicle exterior door handle 17 is changed from the vehicle exterior handle connection lever 150 to the connection pin penetrating lever 120 regardless of the locked / unlocked state of the door lock (the position of the connection pin 400 in the guide slot 133). They are transmitted so that they always rotate integrally in the first rotation direction. Further, as described above, when the connecting pin 400 is set to the unlocked position, the connecting pin penetrating lever 120 and the latch release output lever 130 are connected so as to be integrally rotatable, so that the operation power by the opening operation of the exterior door handle 17 is reduced. Then, it is transmitted to the latch release output lever 130 via the vehicle exterior handle connecting lever 150 and the connecting pin penetrating lever 120.

  Further, as shown in FIG. 16, from the side edge of the outer handle connecting lever 150 facing the second rotation direction of the other lever projection piece 152 toward the fully open lock lever 170 (the front side in FIG. 16). The interlocking contact piece 155 is bent up at a right angle.

  When the vehicle exterior handle connecting lever 150 is rotated in the first rotational direction by the opening operation of the vehicle exterior door handle 17, the fully open lock lever 170 is rotated in the first rotational direction by being pushed by the interlocking contact piece 155. (See FIG. 9).

  The “handle interlocking lever” according to the present invention includes an in-vehicle handle connecting lever 140, a connecting pin penetrating lever 120, and an out-of-vehicle handle connecting lever 150.

  Here, the remote control device 100 is provided with a release actuator 60 (see FIG. 5), and the door latch release force transmission mechanism 100K receives the power of the release actuator 60 and rotates around the main support shaft 102 in the first rotation direction. A rotating actuator interlocking lever 160 is provided. The release actuator 60 is activated when the door latch by the latch mechanism 20K is released by manual operation of the interior door handle 18 or the exterior door handle 17. Specifically, for example, the operation of the electric door opening / closing device is started when either one of the switches 110 and 111 is turned on and the door latch of the rear door lock device 10B is released as the first operating condition (vehicle Until the door 90 starts electric sliding), the latch mechanism 20K is maintained in the door latch release state.

  Further, the release actuator 60 operates under the second operating condition that a remote operation (operation of a remote control key or a door opening / closing button in the vehicle) is performed, and rotationally drives the actuator interlocking lever 160 to release the door latch. .

  As shown in FIG. 17, the actuator interlocking lever 160 extends from the main support shaft 102 to the side opposite to the in-vehicle handle connecting lever 140 (see FIG. 7). The actuator interlocking lever 160 has a center side fan-shaped portion 161 near the main support shaft 102, and a tip side protruding piece 162 protruding from the center side fan-shaped portion 161 to the side opposite to the main support shaft 102. The front end-side projecting piece 162 extends from a position closer to the second rotational direction in the central sector 161 and projects from the intermediate position in the rotational radial direction in the first rotational direction 163. And a second side protruding piece 164 protruding in the first rotation direction from the end portion on the side away from the main support shaft 102. A through hole 165 is formed at the end of the second side protruding piece 164 on the first rotation 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 operates, the open cable 95W is pulled toward the release actuator 60 by the power. As a result, the actuator interlocking lever 160 rotates around the main support shaft 102 in the first rotation direction.

  Further, the interlocking contact piece from the side edge portion of the front end side projecting piece 162 of the actuator interlocking lever 160 facing the second rotation direction toward the fully open lock lever 170 (toward the manual space side in FIG. 17). 166 is bent at a right angle, and from the tip of the lever protrusion 171 of the fully open lock lever 170 (see FIG. 7) toward the actuator interlocking lever 160 (toward the back side of the sheet of FIG. 7) The contact piece 173 is bent at a right angle. These interlocking contact pieces 166 and 173 can contact each other.

  When the release actuator 60 is actuated, the fully open lock lever 170 is rotated in the first rotation direction by being pushed by the interlocking contact piece 166. The actuator interlocking lever 160 is urged in the second rotation direction by a coil spring 176 (see FIG. 5) that urges the fully open lock lever 170 in the second rotation direction. 104 (see FIG. 5) and the actuator interlocking lever 160 are in contact with each other, the actuator interlocking lever 160 and the fully open lock lever 170 are positioned at the original positions shown in FIGS. Note that when the fully open lock lever 170 is urged in the second rotation direction by the contact of the interlocking contact piece 155 of the vehicle exterior handle connection lever 150 and the fully open lock lever 170, the vehicle exterior handle connection lever 150 is also moved to the first position. Although it is urged in two rotation directions, the fully open lock lever 170 is positioned at the original position, so that the vehicle exterior handle connecting lever 150 is also positioned at the original position shown in FIGS.

  By the way, as shown in FIG. 17, in the central fan-shaped portion 161 of the actuator interlocking lever 160, the portion on the first rotation direction side from the tip-side protruding piece 162 (hereinafter referred to as the central interference portion 167) is the guide length. The contact flat surface 167B that protrudes in the rotational radius direction along one side edge portion extending in the longitudinal direction of the hole 133, and the contact flat surface 167B facing the first rotational direction is the guide long hole 133 and the L-shaped first side path 123A. It extends in a straight line parallel to one side extending in the longitudinal direction.

  Further, the distal end portion in the turning radius direction of the center side interference portion 167 is an arcuate 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 arrange | positions in the intermediate part of the edge part of a side, and the L-shaped 2nd edge path | route 123B. In other words, the member guide part 167A of the center side interference part 167 is disposed closer to the main support shaft 102 than the side of the L-type second side path 123B on the main support shaft 102 side. The center end portion of the guide long hole 133 overlaps the rotation region of the center interference portion 167, and the intermediate portion and the outer end portion of the guide long hole 133 rotate the center side interference portion 167. It is located outside the area. That is, the center side interference part 167 can push the connection pin 400 in the first rotation direction by the contact flat surface 167B when the connection pin 400 is located at the unlock position, and the connection pin 400 is unlocked. When located outside the lock position, it is impossible to push the connecting pin 400 in the first rotation direction.

As shown in FIG. 17, the main support shaft 102 side portion of the first side protruding piece 163 is an arc-shaped member guide portion 163A centering on the main support shaft 102, and an L-shaped second side path. It is arranged between the side on the main support shaft 102 side in 123B and the side on the side away from the main support shaft 102. Further, the abutting flat surface 163B of the first side protruding piece 163 facing the first rotation direction extends in parallel with the guide long hole 133 and one side extending in the longitudinal direction of the L-shaped first side path 123A. Yes. And the outer edge part of the guide long hole 133 overlaps with the rotation area | region of the 1st side protrusion piece 163, and the intermediate part and center side edge part of the guide long hole 133 are the 1st side protrusion piece. It is arranged outside the rotation area 163. That is, the first side protruding piece 163 is able to push the connecting pin 400 in a first rotational direction by abutting flat surface 163B when the connecting pin 400 is positioned in the locking position, the connecting pin 400 is 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, a relief groove 168 of the present invention (corresponding to the “blocking portion” of the present invention) is formed in a portion sandwiched between the center side interference portion 167 and the first side protruding piece 163. Has been. The escape groove 168 opens at a side edge portion of the actuator interlocking lever 160 facing the first rotation direction, and extends in an arc shape toward the second rotation direction. The width of the escape groove 168 is approximately twice the width of the connecting pin 400, so that the connecting pin 400 can be moved into the first intermediate position (see FIG. 20) and the second intermediate position (see FIG. 20) in the escape groove 168. 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 protruding piece 163), and the side of the L-shaped second side path 123B on the main support shaft 102 side. The distance from the side is larger than the width of the connecting pin 400 (specifically, the width of the second shaft portion 420 described later), and the connecting pin 400 arranged at the second intermediate position is a relief groove. The inside of 168 is movable along the L-shaped second side path 123B. 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-type second side path 123B on the main support shaft 102 side is The width of the connecting pin 400 is almost the same.

  FIG. 18A shows a detailed configuration of the connecting pin 400. As shown in the figure, the connecting 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. The flanges 401, 401 protrude from the boundary portion between the circular shaft portion 403 and the boundary portion between the non-circular shaft portion 403 and the second shaft portion 420 toward the side.

  The non-circular shaft portion 403 is disposed in the guide long hole 133, and the cross-sectional shape thereof is an oval shape having a two-sided width substantially the same as the width of the guide long hole 133, as shown in FIG. There is no. Specifically, the arcuate surfaces 403A and 403A at both ends in the longitudinal direction are connected by a pair of parallel flat surfaces 403B and 403B, and the pair of flat surfaces 403B and 403B are the width of the guide long hole 133. The connecting pin 400 is prevented from rotating with respect to the guide long hole 133 so as to face both inner surfaces in the direction (extending in the longitudinal direction). In addition, the pair of flange portions 401 and 401 sandwich the lever protrusion 131 from the plate thickness direction, thereby prohibiting the movement of the connecting pin 400 in the axial direction.

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

  On the other hand, the distal end portion of the first shaft portion 410 is a cylindrical portion 412 having a circular cross section. The cylindrical portion 412 is fitted so as to be movable within a long hole 183 (see FIGS. 7 and 12) penetrating the lever protrusion 182 of the locking lever 180.

  The second shaft portion 420 of the connecting pin 400 protrudes from the lever protruding piece 131 of the latch release output lever 130 toward the side opposite 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 square cross section), and the side surface of the second shaft portion 420 is composed of four flat surfaces parallel to the axial direction of the connecting pin 400. (See FIG. 17). Of these four flat surfaces, the two flat surfaces parallel to each other face the turning radius direction (longitudinal direction of the guide slot 133) about the main support shaft 102, and the remaining two flat surfaces are The first rotation direction and the second rotation direction about the main support shaft 102 are directed.

  As shown in FIG. 17, when the connecting pin 400 is located at the unlock position, one flat surface facing the second rotation direction among the four flat surfaces constituting the side surface of the second shaft portion 420. 421 (hereinafter, referred to as “abutting flat surface 421” as appropriate) can come into surface contact with the abutting flat surface 163B of the first lateral protrusion piece 163. Further, when the connecting pin 400 is located at the lock position, the contact flat surface 421 of the second shaft portion 420 can come into surface contact with the contact flat surface 167B of the center side interference portion 167. .

  The configuration of the present embodiment is as described above. Next, the operation of the door latch release force transmission mechanism 100K will be described. When the interior door handle 18 is closed (tilted toward the closing direction) when the vehicle door 90 is in the fully open state, the fully open lock lever 170 is pushed by the rod 105 to move around the main support shaft 102 in the first rotational direction ( It rotates in the clockwise direction in FIG. 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 and ratchet mechanism of the fully open door lock device 10C is released. Thereby, 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 closed (pulled forward) when the vehicle door 90 is fully open (pulled forward), the vehicle exterior handle connection lever 150 is rotated in the first rotation direction by being pulled by the open cable 94W. The connecting pin penetrating lever 120 and the fully open lock lever 170 are integrally rotated in the first rotation direction around the main support shaft 102 by being pushed by the vehicle outer handle connecting lever 150 (see FIG. 9). When the fully open lock lever 170 is rotated 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. Thereby, 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 in a fully opened state, when remote operation is performed without operating the in-vehicle door handle 18 or the out-of-vehicle door handle 17 (operating a remote control key or a door opening / closing button in the vehicle), as shown in FIG. In addition, the release actuator 60 is actuated to rotate the actuator interlocking lever 160 in the first rotational direction, and the fully open lock lever 170 is integrally rotated in the first rotational direction by being pushed by the actuator interlocking lever 160. 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. As a result, the vehicle door 90 can be electrically slid in the closing direction.

  Next, regarding the operation of the door latch release force transmission mechanism 100K when an 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 indicated by the solid line in FIG. 7). ).

  When the door handle 18 is opened by setting the door lock to the “unlocked state” (the connecting pin 400 is indicated by the solid line in FIG. 7), as shown in the change from FIG. 7 to FIG. When the lever 140 rotates around the main support shaft 102 in the first rotation direction and pushes the child lock pin 125, the connecting pin penetrating lever 120 rotates in the first rotation direction. The rotation of the connection pin penetrating lever 120 is transmitted to the latch release output lever 130 via the connection pin 400, and the open cables 91W and 92W are connected to the remote control device 100 by the rotation of the latch release output lever 130 in the first rotation direction. Pulled to the side. When the latch release output lever 130 reaches the vicinity of the rotation end position away from the original position in the first rotation direction, the door latch by the 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 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 part 167 (contact flat surface 167 </ b> B) comes into contact with the connecting 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 penetrating lever 120 are held at the rotation end position away from the original position in the first rotation direction. As a result, even if the hand is released from the vehicle interior door handle 18 and the vehicle interior handle connection lever 140 returns to the original position, the latch mechanism 20K is used until the operation of the electric door opening / closing device starts (the vehicle door 90 starts the electric slide). The door latch release can be maintained (see FIG. 10).

  When the door lock 17 is unlocked and the outside door handle 17 is opened (pulled forward), the outside handle connecting lever 150 moves around the main support shaft 102 as shown in the change from FIG. 7 to FIG. It rotates in the first rotation direction. At this time, the vehicle handle connecting lever 150 pushes the connecting pin penetrating lever 120. Further, since the connecting pin penetrating lever 120 and the latch release output lever 130 are connected by the connecting pin 400, the operating power by the opening operation of the outside door handle 17 causes the outside handle connecting lever 150 and the connecting pin penetrating lever 120 to be operated. To the latch release output lever 130, and these rotate integrally around the main support shaft 102 in the first rotation direction. When the latch release output lever 130 rotates in the first rotation direction, the open cables 91W and 92W are pulled toward the remote control device 100 side. When the latch release output lever 130 reaches the vicinity of the rotation end position away from the original position in the first rotation direction, the door latch by the 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 is satisfied.

  Then, the center side interference part 167 (abutting 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 are pressed. Is held at the rotation end position away from the original position in the first rotation 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 operation of the electric door opening / closing device starts (the vehicle door 90 starts electric sliding). Can maintain the door latch release by the latch mechanism 20K.

  When the door lock is set to the “unlocked state” and the remote operation is performed without opening the interior door handle 18 or the exterior door handle 17, the second operating condition of the release actuator 60 is satisfied. As shown in the change from FIG. 7 to FIG. 10, the actuator interlocking lever 160 rotates around the main support shaft 102 in the first rotation direction, and the center side interference portion 167 pushes the connecting pin 400 to latch. The release output lever 130 rotates in the first rotation direction. Then, as described above, the door latch by each latch mechanism 20K provided in the front door lock device 10A and the rear door lock device 10B is released. Until the electric door opening / closing device starts operating (the vehicle door 90 starts electric sliding), the release of the latch mechanism 20K can be maintained by the power of the release actuator 60. The center-side interference portion 167 of the actuator interlocking lever 160 corresponds to the “first contact portion” of the present invention.

  That is, when both the door lock and the child lock are in the “unlocked state”, the vehicle door 90 can be opened by the opening operation of the interior door handle 18, the opening operation of the exterior door handle 17 and the remote operation of the remote control key or the like. Is possible.

When the interior door handle 18 is opened when the door lock is in the “locked state” (the connecting pin 400 is in the locked position shown by the solid line in FIG. 12 ), as shown in the change in FIGS. The handle connection lever 140 and the connection pin penetrating lever 120 rotate in the first rotation direction, but the connection 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, transmission of power from the connecting pin penetrating lever 120 to the latch release output lever 130 is interrupted. That is, the operating power generated by opening the interior door handle 18 is not transmitted to the latch release output lever 130, so the latch release output lever 130 remains in the original position shown in FIG. Accordingly, the vehicle door 90 is kept closed by the front door lock device 10A and the rear door lock device 10B.

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

  When the door lock is set to the “locked state” and the remote operation is performed without opening the interior door handle 18 or the exterior door handle 17, the second operating 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 rotates around the main support shaft 102 in the first rotation direction, and the first side protruding piece 163 presses the connecting pin 400. The latch release output lever 130 rotates in the first rotation direction. And the door latch by each latch mechanism 20K with which the front door lock device 10A and the rear door lock device 10B are provided is released. The first side protruding piece 163 of the actuator interlocking lever 160 corresponds to a “second contact portion”.

  Thus, in the door latch release force transmission mechanism 100K, when the door lock is in the “locked state”, the vehicle door 90 cannot be opened even if the exterior door handle 17 and the interior door handle 18 are opened, The vehicle door 90 can be opened by remote operation such as a remote control key.

  In summary, in the door latch release force transmission mechanism 100K, when the outside door handle 17 and the inside door handle 18 are opened, when the door lock is in the “unlocked state”, the front door lock device 10A and the rear door lock device 10A The closed holding of the vehicle door 90 by the side door lock device 10B can be released, and the closed holding cannot be released when the door lock is in the “locked state”. When performing remote operation using a remote control key or the like, the vehicle is operated by the front door lock device 10A and the rear door lock device 10B regardless of whether the door lock is “locked” or “unlocked”. The closed holding of the door 90 can be released.

  Note that if the in-car door handle 18 is opened while the child lock is in the “locked state” (the child lock pin 125 is at the position indicated by the two-dot chain line in FIG. 7), the in-car handle connecting lever 140 is moved by the first power. Although it rotates in the moving direction, the child lock pin 125 is disposed at the child lock position and does not come into contact with 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 penetrating lever 120 and the latch release output lever 130 remain in their original positions shown in FIG. 7, and the front door lock device is used regardless of whether the door lock is in the “locked state” or “unlocked state”. The closed holding 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. Even if the child lock is in the “locked state”, if the door lock is “unlocked”, the door handle outside the vehicle 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 rotation end position separated from the original position in the first rotation direction (or the first rotation from the original position). When the actuator interlocking lever 160 and the latch release output lever 130 are not moved due to, for example, a failure of the release actuator 60 or an abnormality in the power transmission path during the rotation in the moving direction), the latch mechanism 20K causes the vehicle door 90 to move. The state in which the closed holding is released (that is, the ratchet 30 is not restored from the position indicated by the two-dot chain line in FIG. 4).

  In such an emergency, the indoor lock operation unit 16 (see FIG. 6) may be operated. Specifically, when an abnormality occurs when the door lock is “unlocked”, a lock operation (moving operation in the closing direction of the vehicle door 90) is performed, and when an abnormality occurs when the door lock is “locked”, unlocking occurs. A lock operation (moving operation in the closing direction of the vehicle door 90) is performed.

  If the lock operation is performed when the door lock is in the “unlocked state”, as shown in FIG. 19, the connecting pin 400 moves from the unlock position to the intermediate position and is disposed outside the rotation area of the center side interference portion 167. The actuator interlocking lever 160 is disconnected from the connecting pin penetrating lever 120 and the latch release output lever 130 (the release actuator 60 is disconnected from the latch mechanism 20K). At the same time, the urging force of the torsion coil spring 129 causes the connecting pin 400 to enter the escape groove 168, and the connecting pin penetrating lever 120 and the latch release output lever 130 rotate together in the second rotational direction to return to the original position. Return. Thereby, 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 returned to a state in which the vehicle door 90 can be held closed. Can be made. Specifically, the connecting pin 400 that moves from the unlocked position to the intermediate position abuts on the first side protrusion 163 of the actuator interlocking lever 160 and is held at the second intermediate position, and is held by the member guide portion 163A. It moves in the escape groove 168 along.

  If the unlocking operation is performed when the door lock is in the “locked state”, the connecting pin 400 moves from the locked position to the intermediate position and is disposed outside the rotation region of the first side protruding piece 163, and is interlocked with the actuator. The lever 160 is disconnected from the connecting pin penetrating lever 120 and the latch release output lever 130 (the release actuator 60 is disconnected from the latch mechanism 20K). Then, due to the biasing force of the torsion coil spring 129, the connection pin 400 enters the escape groove 168, and the connection pin penetrating lever 120 and the latch release output lever 130 rotate integrally in the second rotation direction to return to the original position. To do.

  As described above, in the door latch release force transmission mechanism 100K, when the door interlock is in the “locked state” or the “unlocked state”, when 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 and returned to a state where the vehicle door 90 can be kept closed.

  Further, when the vehicle door 90 that is closed and held by the above-described actuator disconnection operation (lock / unlock operation by the indoor lock operation unit 16) is opened, the unlock operation may be performed by the indoor lock operation unit 16. Specifically, when the actuator disconnecting operation is performed, the center side interference portion 167 of the actuator interlocking lever 160 overlaps the center side end portion (unlock position) of the guide long hole 133 as shown in FIG. When the unlocking operation of the indoor lock operation unit 16 is performed in this state, the connecting pin 400 moves in the escape groove 168 from the second intermediate position to the center side as shown in the change from FIG. 19 to FIG. Then, the member abuts against 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 penetrating lever 120 to the latch release output lever 130. On the other hand, since the connecting pin 400 is disposed outside the rotation region of the center side interference portion 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 separated from the latch mechanism 20K).

  In addition, when the lock operation is performed by the indoor lock operation unit 16 after the actuator disconnection operation (lock / unlock operation by the indoor lock operation unit 16), the connecting pin 400 is disposed at the second intermediate position, and the interior door handle 18 and the door handle 17 outside the vehicle are in a locked state in which the closed holding of the vehicle door 90 cannot be released.

  Of the side edge portion of the L-shaped first side path 123A of the connecting pin penetrating lever 120 that faces the first rotation direction, a portion that overlaps the rotation region of the center side interference portion 167 of the actuator interlocking lever 160 (that is, The portion that is in contact with the connecting pin 400 in the unlock position) is a third contact edge 123T1 corresponding to the “third contact portion” of the present invention, and is outside the rotation region of the central interference portion 167. (That is, the portion that contacts the connecting pin 400 at the first intermediate position) is a fourth contact edge 123T2 corresponding to the “fourth contact portion” of the present invention (FIGS. 19 and 20). reference).

  Then, when the outside door handle 17 is opened with the connecting pin 400 disposed at the first intermediate position, the connecting pin 400 passes outside the member guide portion 167A of the center side interference portion 167, so that the actuator stopped abnormally. With the interlocking lever 160 (release actuator 60) disconnected from the latch mechanism 20K, the vehicle exterior handle connecting lever 150, the connecting pin penetrating lever 120, and the latch release output lever 130 rotate integrally in the first rotation direction, and the open cables 91W and 92W Is pulled to the remote control device 100 side. Accordingly, the holding 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. Note that the locked state of the child lock is invalid with respect to the opening operation of the door handle 17 outside the vehicle, so that the vehicle door is opened by the opening operation of the door handle 17 regardless of whether the child lock is locked or unlocked. It is possible to open the vehicle door 90 by releasing the 90 holding. If the child lock is unlocked, the vehicle door 90 can be opened by opening the in-vehicle door handle 18 as in the case of the out-of-vehicle door handle 17.

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

  Further, in the door latch release force transmission mechanism 100K, the center-side interference portion 167 that contacts the connecting pin 400 at the unlocked position of the actuator interlocking lever 160, and the first side protruding piece 163 that contacts the connecting pin 400 at the locked position, Since the release groove 168 opened at the edge between the release actuator 60, the release actuator 60 rotates the latch release output lever 130, and the release mechanism 60 is lost in the state in which the latch mechanism 20K is unlatched, so that it does not move. In this case, the connecting pin 400 is disposed at an intermediate position between the locked position and the unlocked position and received in the escape groove 168, so that the latch release output lever 130 and the latch mechanism 20K are separated from the release actuator 60, and the vehicle door 90 can be closed back to a latchable state.

  Moreover, the escape groove 168 has a width within which the connecting pin 400 can move between the first intermediate position and the second intermediate position, and contacts the connecting pin penetrating lever 120 with the connecting pin 400 in the unlocked position. Apart from the third abutting edge portion, the fourth abutting edge portion that abuts on the connecting pin 400 at the first intermediate position without contacting the connecting pin 400 at the second intermediate position is provided. And the latch release output lever 130 and the latch mechanism 20K are disconnected from the release actuator 60 and the vehicle door 90 is latched in the closed state, and then the connecting pin 400 is disposed at the first intermediate position. The latch 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. By the inner door handle 18 and the exterior door handle 17 can be locked unable to release the latch of the vehicle door 90.

  In the present embodiment, the operation when the indoor lock operation unit 16 is operated when opening the vehicle door 90 closed by the actuator disconnecting operation or the actuator disconnecting operation is illustrated, but the remote control key is operated, Even when a key is inserted into a key cylinder provided on the outdoor surface of the door 90 and a lock / unlock operation is performed, the remote control device 100 can be operated in the same manner as when the indoor lock operation unit 16 is operated. That is, remote control keys and key cylinders are also included in the “lock switching means” of the present invention. Further, as described above, by operating the locking actuator 185, the remote control device 100 can be operated in the same manner as when the indoor lock operation unit 16 is operated. In summary, at least one of the indoor lock operation unit 16, the remote control key, the key cylinder, and the locking actuator 185 is the “lock switching means” of the present invention.
