JP 2003-120102 A

  However, according to the above prior art, there is a possibility that the latch open lever is pushed down by the grip portion of the outside handle moving in the pulling direction due to the impact at the time of a side collision, and the connecting lever moving downward. This is because when the door panel is deformed at the time of a side collision, the grip portion of the outside handle easily moves in the pulling direction due to the influence of inertia or the like.

  In view of the above facts, an object of the present invention is to provide a vehicle door structure that can prevent a door latch from being released even when subjected to an impact during a side collision.

  According to the first aspect of the present invention, there is provided a vehicle door structure provided with a door lock device for releasing a latch by moving a connecting lever connected to an outside handle attached to the door outer panel downward and pushing down the latch open lever. And the high rigidity part whose rigidity is higher than the general surface of the said door outer panel is provided from the part to which the said outside handle of the said door outer panel was attached to the lower part side of the said door outer panel.

  According to a second aspect of the present invention, in the vehicle door structure according to the first aspect, the high-rigidity portion is composed of a reinforcing member coupled to an inner surface of the door outer panel in the vehicle width direction. .

  According to the first aspect of the present invention, the high rigidity portion having higher rigidity than the general surface of the door outer panel is provided from the portion of the door outer panel to which at least the outside handle is attached to the lower side of the door outer panel. When the lower side of the door outer panel is deformed inward in the vehicle width direction at the time of a side collision, the behavior of the door outer panel can be controlled so that the door outer panel around the part to which the outside handle is attached is deformed outward in the vehicle width direction. Accordingly, the outside handle attached to the door outer panel rotates outward in the vehicle width direction with the lower side of the door outer panel as a fulcrum, and the connecting lever connected to the outside handle easily moves upward. For this reason, it is possible to prevent the latch open lever from being pushed down at all or to be pushed down slightly. Therefore, it is possible to prevent the door latch from being released even if it receives an impact during a side collision.

  According to the second aspect of the present invention, since the high-rigidity portion is composed of the reinforcing member coupled to the inner surface in the vehicle width direction of the door outer panel, the high-rigidity portion of the door-outer panel depends on the shape and the coupling position of the reinforcing member. Position adjustment is easy. As a result, the behavior of the door outer panel can be more reliably controlled at the time of a side collision, and the door latch can be prevented from being released even if it receives an impact at the time of a side collision.

  As described above, the vehicle door structure according to the first aspect of the present invention has an excellent effect that the door latch can be prevented from being released even when receiving an impact during a side collision.

  The vehicle door structure according to the second aspect of the present invention has an excellent effect that the door latch can be more reliably prevented from being released even when an impact is received during a side collision.

  Hereinafter, a first embodiment of a vehicle door structure according to the present invention will be described with reference to FIGS. In these drawings, an arrow FR appropriately shown indicates the vehicle front side, an arrow UP indicates the vehicle upper side, and an arrow OUT indicates the vehicle width direction outer side.

  1 and 2 show the overall configuration of the vehicle door structure according to the present embodiment. As shown in FIG. 1, a front door opening 12 and a rear door opening 14 are formed on the side of the body body 11 of the vehicle 10. A front side door 16 is attached to the front door opening 12 so as to be opened and closed by a hinge 18, and a rear side door 20 is attached to the rear door opening 14 so as to be opened and closed by a hinge 22.

  As shown in FIGS. 1 and 2, the front side door 16 includes a door outer panel 24 on the vehicle width direction outer side and a door inner panel 26 on the vehicle width direction inner side. An outside handle 30 is attached to the upper side of the door outer panel 24. The outside handle 30 is provided with a grip portion 32 that is operated in the pulling direction (arrow A direction) when the front side door 16 is opened.

  Further, a reinforcing member 28 is joined to the inner surface of the door outer panel 24 in the vehicle width direction from a portion where the outside handle 30 is attached to a lower side of the door outer panel 24 by welding or the like. By joining the reinforcing member 28 to the inner surface of the door outer panel 24 in the vehicle width direction, a highly rigid portion having higher rigidity than other portions of the door outer panel 24 is configured. In the present embodiment, a rectangular metal plate having a flange at the edge is used as the reinforcing member 28.

  As shown in FIG. 3, a moving member 34 connected to the grip portion 32 is disposed inside the door outer panel 24 so as to pass through an opening 24 </ b> A formed in the door outer panel 24. Is configured to be movable in a guide portion (not shown) fixed inside the door outer panel 24.

  Inside the door outer panel 24, a shaft 42 supported by a bearing portion 40 formed in the handle escutcheon 38 and a handle lever 44 that rotates around the shaft 42 as a rotation axis are disposed. A main body portion 44A of the handle lever 44 is formed in a substantially inverted triangular shape, and an arm 44B is formed at the apex portion on the lower side of the main body portion 44A so as to protrude obliquely downward on the inner side in the vehicle width direction. The tip of the arm 44B is locked to a convex locking portion 34A formed on the moving member 34. As a result, when the moving member 34 moves outward in the vehicle width direction, the handle lever 44 rotates in the opening direction (clockwise direction in the drawing) by being pulled by the arm 44B locked by the locking portion 34A. It has become.

  A connecting lever 48 that is pivotally supported at one end by a shaft 46 so as to be rotatable is provided at the apex angle portion on the inner side in the vehicle width direction of the main body 44A. The connecting lever 48 is made of a long plate-like member arranged along the vehicle vertical direction, and the other end of the connecting lever 48 is an engaging portion that engages with a roller 52 provided at the end of the latch open lever 50. 49 is formed. The roller 52 of the latch open lever 50 and the shaft 46 of the connecting lever 48 are arranged so that their axes are substantially parallel. The engaging portion 49 is formed in a bifurcated shape, and includes a substantially inverted U-shaped slit portion 49B between the two leg portions 49A. The width of the slit portion 49B is slightly larger than the diameter of the roller 52, and the roller 52 is inserted into the slit portion 49B.

  The latch open lever 50 is attached to the door lock device 56 so as to rotate around a shaft 54 disposed on the inner side in the vehicle width direction from the roller 52. The latch open lever 50 is engaged with a detent lever (not shown) of the door lock device 56. When the door lock is released, the latch open lever 50 is rotated downward by the connecting lever 48 to act on the detent lever to lock the door. A latch (not shown) of the device 56 allows the door to be pivoted to the door opening allowance position. That is, the latch provided in the door lock device 56 is configured to be removable from a striker (not shown) provided on the vehicle body side.

  Further, a counterweight 58 is provided at the apex angle portion on the outer side in the vehicle width direction of the main body portion 44 </ b> A of the handle lever 44. The counterweight 58 is set so that the center of gravity is slightly inside the vehicle width direction with respect to the center of the shaft 42. Further, a torsion coil spring (not shown) is wound around the shaft 42, and the grip portion 32 and the handle lever 44 are directed to the normal position (the position shown in FIG. 3) before operation by the action of the torsion coil spring. Is energized.

  As shown in FIG. 3, when the front side door 16 is opened, the grip portion 32 of the outside handle 30 is moved outward in the vehicle width direction against the urging force of the torsion coil spring wound around the shaft 42 ( Pull in the direction of arrow A) to perform the opening operation. Then, as shown in FIG. 4, the moving member 34 connected to the grip portion 32 moves outward in the vehicle width direction, and the arm 44 </ b> B of the handle lever 44 locked to the locking portion 34 </ b> A of the moving member 34. Is pulled, and the handle lever 44 rotates in the opening direction (clockwise direction in the figure) with the shaft 42 as a fulcrum. With the rotation of the handle lever 44, the connecting lever 48 pivotally supported by the shaft 46 is pushed downward, and the roller 52 engaged with the engaging portion 49 of the connecting lever 48 is pulled to latch. The open lever 50 rotates in the opening direction (counterclockwise direction in the figure) with the shaft 54 as a fulcrum. As a result, the latch of the door lock device 56 is released, and the front side door 16 can be opened.

  Next, the operation and effect of this embodiment will be described.

  On the inner side in the vehicle width direction of the door outer panel 24, there is provided a high-rigidity portion in which a reinforcing member 28 is coupled from a portion where the outside handle 30 is attached to the lower side of the door outer panel 24. The high-rigidity part 24 is not easily deformed in a bending direction. Therefore, as shown in FIG. 5, when the bumper 102 of the counterpart vehicle 100 collides with the lower side of the door outer panel 24, the lower side of the door outer panel 24 is deformed inward in the vehicle width direction (arrow B direction). Thus, the behavior of the door outer panel 24 can be controlled such that the door outer panel 24 around the part to which the outside handle 30 is attached is deformed outward in the vehicle width direction (arrow C direction).

  As shown in FIG. 6, when the periphery of a portion of the door outer panel 24 to which the outside handle 30 is attached is deformed outward in the vehicle width direction, the outside handle 30 is in a normal position (shown in FIG. 3) that faces obliquely upward. Rotate downward compared to the state. As a result, the connecting lever 48 interlocked with the outside handle 30 moves upward, and the inner part of the slit portion 49B of the engaging portion 49 formed at the lower end of the connecting lever 48 moves away from the roller 52 of the latch open lever 50. That is, since the distance between the back part of the slit part 49B and the roller 52 increases, it is possible to prevent the back part of the slit part 49B of the engaging part 49 from pushing the roller 52 and pushing down the latch open lever 50 due to an impact at the time of a side collision. . Therefore, it is possible to prevent the latch of the door lock device 56 from being released even if an impact is received during a side collision.

  Further, since the reinforcing member 28 is coupled to the inner side in the vehicle width direction of the door outer panel 24 to constitute the highly rigid portion, the position of the highly rigid portion can be easily adjusted depending on the shape of the reinforcing member 28 and the coupling position. For this reason, the behavior of the door outer panel 24 at the time of a side collision can be controlled more reliably.

  On the other hand, as shown in FIG. 7, in the front side door 110 in which the reinforcing member is not coupled to the door outer panel 112, if the bumper 102 of the counterpart vehicle 100 collides with the lower side of the door outer panel 112, the door outer panel 112 is thin. Therefore, it deforms locally. Therefore, the door outer panel 112 around the part to which the outside handle 30 is attached is not deformed outward in the vehicle width direction, and the outside handle 30 cannot be rotated downward with respect to the normal position.

  Further, the handle lever 44 is provided with a counterweight 58 so as to exert an inertia in a direction opposite to a pulling direction of the grip portion 32 of the outside handle 30 at the time of a side collision, and to cancel each other's force. That is, the counterweight 58 is set so as to suppress the latch open lever 50 from being pushed down with respect to the acceleration in the collision direction. However, even in such a configuration, when acceleration opposite to the collision direction at the time of a side collision occurs, the latch open lever 50 works to encourage the depression. In an actual side collision phenomenon, an acceleration opposite to the collision direction often occurs due to complicated deformation of the door outer panel 112. Therefore, there is a possibility that the counterweight 58 works in a direction that encourages the latch open lever 50 to be pushed down.

  On the other hand, in this embodiment, the door outer panel 24 around the part to which the outside handle 30 is attached is deformed outward in the vehicle width direction, so that the outside handle 30 is in a normal position facing obliquely upward (FIG. 3). Rotate downward compared to (see). As a result, the connecting lever 48 interlocked with the outside handle 30 moves upward, so that the latch of the door lock device 56 can be prevented from being released.
