  However, since this prior art is configured such that the outer tube is pulled together with the inner wire to move the restricting member to prevent the door lock from being released, the door lock is released when the outer tube is not pulled in a side collision. Can not be prevented.

  In view of the above-described facts, an object of the present invention is to provide a vehicle door structure that can stably prevent a door lock from being released in a side collision.

The vehicle door structure according to claim 1 is arranged between the door outer panel constituting the outer plate and the door inner panel constituting the inner plate in the side door, and is pulled in one direction by pulling the wire when the door is opened. And a lock pin for releasing the door lock state in which the side door is closed, and the door outer panel in a state of being separated from the door outer panel and disposed through the base member to which the lock pin is attached. arranged locking pin and with are integrally provided Te in the vehicle width direction outer side of the locking pin adjacent the locking pin and the vehicle longitudinal direction as viewed from the side of the vehicle, to the vehicle width direction inside of the door outer panel during a side collision of the vehicle bending around the tip of the tilted vertical wall in a direction apart from the locking pin taken to toward the vehicle lower side with the deformation Has a stopper for restricting the movement of the lock pin as the door locked state are arranged on the movement path of the lock pin moves to the inside in the vehicle width direction is not released, the and.

  In the first aspect of the invention, the lock pin is disposed between the door outer panel constituting the outer plate and the door inner panel constituting the inner plate in the side door. The lock pin moves in one direction when the wire is pulled when the door is opened, thereby releasing the door lock state in which the side door is closed.

Further , the stopper is disposed to face the door outer panel while being separated from the door outer panel. The stopper is provided integrally with the lock pin via a base member to which the lock pin is attached, and is disposed outside the lock pin in the vehicle width direction. The stopper moves inward in the vehicle width direction along with the deformation of the door outer panel inward in the vehicle width direction at the time of a side collision, and is arranged on the movement locus of the lock pin. Thereby, the movement of the lock pin is restricted so that the door lock state of the side door is not released. That is, even if the lock pin is pulled by the wire, the lock pin interferes with the stopper, so that the movement of the lock pin is restricted. Thereby, the door lock state is maintained for the side door.

Here, since the stopper restricts the movement of the lock pin so that the door lock state of the side door is not released, if the lock pin can interfere with the stopper within the range where the door lock state is not released. good. Therefore, the lock pin may be configured to be able to move within the range in which the door lock state of the side door is not released, or the lock pin may not move (the movement of the lock pin is prevented). Also good. Further , the stopper is disposed adjacent to the lock pin in the vehicle front-rear direction in a side view of the vehicle, and is normally disposed on the inner side in the vehicle width direction of the door outer panel and on the outer side of the lock pin in the vehicle width direction. For this reason, when the lock pin is pulled by the wire, the lock pin moves, and the door is unlocked from the side door. On the other hand, when the door outer panel is deformed inward in the vehicle width direction at the time of a side collision, the stopper is bent and disposed on the movement locus of the lock pin. Thereby, even if the lock pin is about to be pulled by the wire, the lock pin interferes with the stopper, so that the movement of the lock pin is restricted and the side door is maintained in the door lock state.

As described above, the vehicle door structure according to the first aspect of the present invention has an excellent effect that the release of the door lock can be stably prevented in the case of a side collision. Moreover, since the release of the door lock can be stably prevented by bending the stopper at the time of a side collision, there is an excellent effect that the configuration is simple.

  The stopper 74 is provided between the lock pin 50 and the holder 72 in a side view of the vehicle and is disposed adjacent to the lock pin 50 as shown by a solid line in FIG. Moreover, the stopper 74 is arrange | positioned in the vehicle width direction inner side of the door outer panel 20 and the vehicle width direction outer side of the lock pin 50, as the solid line of FIG.7 (B) shows. Here, in FIGS. 7A and 7B, the solid line indicates the state before the side collision, and the virtual line indicates the state after the side collision.

  Here, as shown in FIG. 4, the bracket 68 is provided with a vertical wall 76 erected outward in the vehicle width direction, and the stopper 74 is directed downward from the tip of the vertical wall 76. It is overhanging. That is, the stopper 74 is provided integrally with the bracket 68, and the stopper 74 is disposed on the outer side of the lock pin 50 in the vehicle width direction.

  7A, the straight line P along the width direction of the vertical wall 76 and the straight line Q along the width direction of the stopper 74 have angles with respect to the straight line along the vehicle front-rear direction. It is formed to have it. In addition, an arc-shaped cutout 74A is cut out at a substantially central portion in the longitudinal direction of the stopper 74, and the stopper 74 forms an obtuse angle when viewed from the side of the vehicle with reference to the cutout 74A. It is bent.

  The base side of the stopper 74 extends obliquely forward and downward from the front end of the vertical wall 76, and approaches the lock pin 50 side from the front end of the vertical wall 76 toward the notch 74A. ing. Further, the distal end side of the stopper 74 extends downward so as to be substantially parallel to the lock pin 50. The straight line R connecting the notches 74A has a slight angle with respect to the straight line along the vehicle longitudinal direction, and is formed so as to have an angle with respect to the straight line P and the straight line Q. Yes.

  On the other hand, as shown in FIGS. 1 and 2, a door outside handle 78 is provided on the upper side of the door lock device 18 outside the side door 12 in the vehicle width direction on the vehicle front side. The door outside handle 78 is provided with a rotation center portion O (see FIG. 2) on the rear side along the vehicle longitudinal direction. When the door outside handle 78 is pulled toward the front side, the rotation center portion O is centered. The door outside handle 78 is rotatable.

  Here, the door outside handle 78 is provided with a link member (not shown) that moves following the rotation of the door outside handle 78. A pipe 80 shown in FIG. 1 is connected to the link member, and the pipe 80 is movable along with the movement of the link member. An L-shaped transmission member 84 provided on the surface of the cover 82 is connected to the pipe 80 via a connector 81, and the transmission member 84 is centered on the shaft portion 86 as the pipe 80 moves. It is designed to rotate.

  The shaft portion 86 is fixed to the transmission member 84, and the shaft portion 86 is rotated by the rotation of the transmission member 84. The shaft portion 86 is provided through the cover 82. A lock piece 88 fixed to the shaft portion 86 is disposed in the cover 82. The other end of the wire 52 is attached to the lock piece 88, and the wire 52 is pulled by the rotation of the lock piece 88.

  The lock piece 88 is provided with a torsion spring (not shown). When the door outside handle 78 is pulled toward the front side, an elastic force is accumulated in the torsion spring. For this reason, when the hand is released from the door outside handle 78, the lock piece 88 returns to the original state by the restoring force of the torsion spring. Thereby, the door outside handle 78 returns to the original state via the shaft portion 86, the transmission member 84, the pipe 80, and the like.

(Operation and effect of vehicle door structure)
When the door outside handle 78 shown in FIG. 1 is pulled to the near side, the transmission member 84 is rotated in the direction of arrow A by a pipe 80 connected to a link member (not shown). As a result, the shaft portion 86 of the transmission member 84 rotates, and the lock piece 88 fixed to the shaft portion 86 rotates together with the shaft portion 86 in the arrow B direction. For this reason, the other end portion of the wire 52 attached to the lock piece 88 is pulled in the arrow B direction, and the lock pin 50 moves in the arrow C direction. As a result, the engagement state between the latch and the striker 16 (see FIG. 2) is released, and the side door 12 is slidable (can be opened).

  Here, in the present embodiment, as indicated by the solid line in FIG. 7B, the stopper 74 is disposed inside the door outer panel 20 in the vehicle width direction and outside the lock pin 50 in the vehicle width direction. Therefore, when the side door 12 is opened, the lock pin 50 does not interfere with the stopper 74 even if the lock pin 50 moves (moves from the front side of the drawing toward the back side) by pulling the wire 52.

  Moreover, the stopper 74 is arrange | positioned between the lock pin 50 and the holder 72 by the vehicle side view as shown by the continuous line of FIG. 7 (A). A stopper 74 is disposed adjacent to the lock pin 50 on the rear side of the lock pin 50 in the vehicle front-rear direction. 7B, when the door outer panel 20 is deformed inward in the vehicle width direction at the time of a side collision, the stopper 74 is centered on the front end portion of the vertical wall 76 along with the deformation of the door outer panel 20. Bends inward in the vehicle width direction.

  As a result, the stopper 74 is disposed on the movement locus of the lock pin 50. By arranging the stopper 74 on the movement locus of the lock pin 50, even if the lock pin 50 is about to be pulled by the wire 52, the lock pin 50 interferes with the stopper 74, so that the movement of the lock pin 50 is prevented. Be regulated. Thereby, the door lock state is maintained for the side door 12. Therefore, it is possible to stably prevent the door lock from being released during a side collision.

  Here, since the stopper 74 restricts the movement of the lock pin 50 so that the door lock state of the side door 12 is not released, the lock pin 50 can interfere with the stopper 74 within a range where the door lock state is not released. It only has to be. Therefore, the lock pin 50 may be configured to be able to move within a range where the door lock state of the side door 12 is not released, or may be configured to prevent the lock pin 50 from moving.

  In the present embodiment, as the door outer panel 20 is deformed, the stopper 74 bends inward in the vehicle width direction around the front end portion of the vertical wall 76 as shown in FIG. 7B. Since the stopper 74 is arranged on the movement trajectory of the lock pin 50, a complicated mechanism is unnecessary and can be dealt with easily.

  Further, as shown in FIG. 4, the stopper 74 protrudes downward from the front end portion of the vertical wall 76 erected outward in the vehicle width direction at the bracket 68. 7A, the straight line P along the width direction of the vertical wall 76 and the straight line Q along the width direction of the stopper 74 are respectively angled with respect to the straight line along the vehicle front-rear direction. It is formed to have. The base side of the stopper 74 extends obliquely forward and downward from the front end of the vertical wall 76, and the front end side of the stopper 74 extends downward so as to be substantially parallel to the lock pin 50. Has been issued. The straight line R connecting the notches 74 </ b> A has a slight angle with respect to the straight line along the vehicle front-rear direction and is formed so as to have an angle with respect to the straight line P and the straight line Q.

  At the time of a side collision, the door outer panel 20 (see FIG. 7B) is deformed inward in the vehicle width direction, but with the configuration described above, a bend line where the door outer panel 20 bends is surely applied to the vertical wall 76 and the stopper 74. In this way, the stopper 74 is reliably bent.

  Here, the stopper 74 is bent toward the inner side in the vehicle width direction with the front end portion of the vertical wall 76 as the center, but the notch 74A formed at the substantially central portion in the longitudinal direction of the stopper 74. Further bending may be performed at the portion, and the bent portion may be disposed on the movement locus of the lock pin 50.

  Furthermore, in this embodiment, as shown in FIGS. 4 and 6, a stopper 74 is provided integrally with a bracket 68 to which a holder 72 that holds one end portion 70 </ b> A of the outer tube 70 that covers the wire 52 is fixed. Yes. That is, since the bracket 68 and the stopper 74 can be used together by changing the mold shape of the bracket 68, the cost can be reduced as compared with the case where a separate stopper member is provided. Of course, the stopper 74 may be provided on a member other than the bracket 68.

  Moreover, although the door structure for vehicles which concerns on this embodiment demonstrated the slide door, it is applicable also with a swing door.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and other various modifications can be made without departing from the spirit of the present invention. It is.
