It is located near the bracket 15. It is preferable that the inclined portion 38 is provided so as to incline diagonally upward on the door outer panel 3 side from a position below the lowest point 25B of the open rod 25. That is, the inclined portion 38 is provided so as to avoid the movable region of the open rod 25 that moves downward.

Further, the upper end edge 38B of the inclined portion 38 in the vehicle vertical direction, that is, the upper end edge 38B on the door outer panel 3 side is located above the lower end portion 25A of the open rod 25 in the vehicle vertical direction, and the cross-section hat-shaped apparinose 8 It is arranged so as to face the bottom surface portion 8C connecting the pair of vertical wall portions 8B. Preferably, the upper end edge 38B of the inclined portion 38 in the vehicle vertical direction is arranged so as to face the central portion of the bottom surface portion 8C of the apparel informs 8 in the vehicle vertical direction. Further, the upper end edge 38B of the inclined portion 38 in the vertical direction of the vehicle and the bottom surface portion 8C of the apparinose 8 are separated by a predetermined distance.

Further, the rod pushing member 26 extends upward substantially at a right angle from the side edge of the inclined portion 38 facing the door lower frame 13 in a substantially triangular shape in front view (see FIG. 2), and the bottom surface portion 13A of the door lower frame 13 It has a fixing portion (first extending portion) 39 which is welded and fixed by spot welding or the like. The inner side edge of the fixed portion 39 in the vehicle width direction is formed along the inner side edge of the bottom surface portion 13A of the door lower frame 13 in the vehicle width direction. In FIG. 2, the welded portion of the fixed portion 39 is indicated by a cross. Here, the door lower frame 13 functions as an example of the door member. The fixing portion 39 functions as an example of the first extending portion.

Therefore, the rod pushing member 26 is formed in an L shape in a side view by the inclined portion 38 and the fixing portion 39, and a gap of a distance L1 is formed between the door lock device 22 and the fixing portion 39 in the vehicle width direction. Is formed. Further, the rod pushing member 26 is formed with a pair of reinforcing ribs 41 recessed upward at positions where the ridge line formed by the inclined portion 38 and the fixing portion 39 is substantially divided into three in the longitudinal direction.

Further, as shown in FIG. 2, the distance L2 in the vehicle width direction from the lower end portion 25A of the open rod 25 to the inclined portion 38 of the rod pushing member 26 is the vehicle width between the door lock device 22 and the door lower frame 13. The distance is set to be shorter than the distance L1 in the direction by a predetermined length (for example, about 5 mm to 20 mm). As a result, as will be described later, when the inclined portion 38 of the rod pushing member 26 comes into contact with the lower end portion 25A of the open rod 25 at the time of a side collision, a predetermined position is provided between the door lock device 22 and the door lower frame 13. It is configured so that a gap of a distance (for example, about 5 mm to 20 mm) can be formed (see the central figure of FIG. 4).

Next, an example of deformation of the door lock structure 11 when the vehicle door 1 configured as described above is subjected to a side collision will be described with reference to FIG. The figure on the left of FIG. 4 shows a state before the door outer panel 3 is subjected to a side collision. The central view of FIG. 4 shows a state in which the lower end portion 25A of the open rod 25 is in contact with the inclined portion 38 of the rod pushing member 26 in response to a side collision. The figure on the right of FIG. 4 shows a state after receiving a side collision.

As shown in the left view of FIG. 4 and the center view of FIG. 4, when the vehicle door 1 receives a side collision, the apparel infoce 8 moves inward in the vehicle width direction together with the door outer panel 3. As a result, the bottom surface portion 8C of the apparinose 8 abuts on the upper end edge 38B of the inclined portion 38 of the rod push-up member 26, and the rod push-up member 26 and the door lower frame 13 to which the rod push-up member 26 is fixed are brought into contact with each other. Push it inward in the width direction of the vehicle.

As a result, the inclined portion 38 of the rod pushing member 26 pushed inward in the vehicle width direction comes into contact with the lower end portion 25A of the open rod 25 that has moved slightly downward due to the deformation of the door outer panel 3, and the open rod 25 The downward movement is blocked. That is, the downward rotation of the open lever 23 is prevented, the engagement between the door lock device 22 and the striker 31 is maintained, and the locked state of the vehicle door 1 is maintained.

Subsequently, as shown in the central view of FIG. 4 and the right figure of FIG. 4, the rod push-up member 26 and the rod push-up member 26 were fixed via the door outer panel 3 and the apparition informose 8. The door frame 13 is integrally pushed further inward in the vehicle width direction. As a result, the lower end portion 25A of the open rod 25 that comes into contact with the inclined portion 38 of the rod pushing member 26 moves upward in the vehicle along the inclined portion 38 as the rod pushing member 26 moves inward in the vehicle width direction. Pushed up to the side.

As a result, the movement of the open rod 25 and the open lever 23 to the lower side of the vehicle is restricted, and it is possible to prevent the vehicle door 1 from opening with a simple configuration in the event of a side collision. Further, in the event of a side collision, the rod push-up member 26, which is a fixing component fixed to the door lower frame 13 which is not involved in unlocking and locking the vehicle door 1, hits the apparinose 8 attached to the door outer panel 3, so that the side surface It is easy to manage the collision mode of parts at the time of collision.

Further, since the flat plate-shaped inclined portion 38 of the rod pushing member 26 hits the open rod 25 at an angle, not only the mounting position of the rod pushing member 26 with respect to the door lower frame 13 varies, but also the mounting bracket 15 and the door inner panel 18 It is possible to easily absorb variations in the degree of deformation of other parts such as, and variations in the timing of deformation. Further, it is not necessary to attach a part to the open rod 25, and the space required for the open rod 25 to move in the vertical direction can be saved.

The vehicle door lock structure of the present invention is not limited to the configuration, structure, appearance, shape, processing procedure, etc. described in the above embodiment, and various changes and improvements are made without changing the gist of the present invention. , Additions and deletions are possible. In the following description, the same reference numerals as those of the vehicle door 1 and the like according to the above embodiments of FIGS. 1 to 4 indicate the same or equivalent parts as those of the vehicle door 1 and the like according to the embodiment.

[Other First Embodiment]
(A) For example, a schematic configuration of a door lock structure 53 of a vehicle door 51 according to another first embodiment will be described with reference to FIGS. 5 and 6. As shown in FIGS. 5 and 6, the door lock structure 53 of the vehicle door 51 has substantially the same configuration as the door lock structure 11 of the vehicle door 1 according to the embodiment. However, the difference is that a metal rod pushing member 55 is provided instead of the rod pushing member 26.

Specifically, the rod pushing member 55 is lower than the lower end portion 25A of the open rod 25 that moves to the lower side of the vehicle (in the direction of arrow 36) by the opening operation of the door handle 21 (the operation of rotating in the direction of arrow 35). It has a flat plate-shaped inclined portion 38 that inclines diagonally upward from the position on the door outer panel 3 side. The inclined portion 38 is formed in a substantially rectangular shape, and is located in the vicinity of the bottom surface portion 13A with the side edge on the front side of the vehicle separated from the bottom surface portion 13A of the door lower frame 13, and the bottom surface portion of the door lower frame 13. It is arranged so as to intersect with respect to 13A. Further, the lower end edge 38A of the inclined portion 38 in the vehicle vertical direction is located in the vicinity of the mounting bracket 15 attached to the lower end portion of the door lower frame 13.

Further, the upper end edge 38B of the inclined portion 38 in the vehicle vertical direction, that is, the upper end edge 38B on the door outer panel 3 side is located above the lower end portion 25A of the open rod 25 in the vehicle vertical direction. Then, the rod push-up member 55 extends outward in the vehicle width direction from the upper end edge 38B of the inclined portion 38 to the bottom surface portion 8C of the apparite informs 8 (reinforcing member) over the entire width, and further extends to the outer end in the vehicle width direction. It has a side view inverted L-shaped fixing portion (second extending portion) 57 extending downward at a substantially right angle along the bottom surface portion 8C over the entire width from the edge. Here, the fixing portion 57 functions as an example of the second extending portion. The Appari Infoce 8 functions as an example of a door member.

The mounting wall portion 57A extending downward at a substantially right angle along the bottom surface portion 8C from the outer edge of the fixed portion (second extending portion) 57 in the vehicle width direction is the bottom surface portion 8C of the apparing weld 8 (reinforcing member). It is fixed by welding by spot welding or the like. In FIG. 6, the welded portion of the fixed portion (second extending portion) 57 is indicated by a cross. As a result, when the vehicle door 51 is subjected to a side collision, the door outer panel 3 and the apparie infose 8 move inward in the vehicle width direction, and the apparel informose 8 and the rod push-up member 55 integrally move inward in the vehicle width direction. Moving.

Further, as shown in FIG. 5, the distance L2 in the vehicle width direction from the lower end portion 25A of the open rod 25 to the inclined portion 38 of the rod pushing member 55 is between the door lower frame 13 and the bottom surface portion 8C of the apparinose 8. The distance is set to be shorter than the distance L3 in the vehicle width direction by a predetermined length (for example, about 5 mm to 20 mm). As a result, as will be described later, when the inclined portion 38 of the rod pushing member 55 comes into contact with the lower end portion 25A of the open rod 25 at the time of a side collision, between the door lower frame 13 and the bottom surface portion 8C of the apparinose 8. A gap of a predetermined distance (for example, about 5 mm to 20 mm) can be formed in the center (see the central figure of FIG. 7).

Next, an example of deformation of the door lock structure 53 when the vehicle door 51 configured as described above is subjected to a side collision will be described with reference to FIG. 7. The figure on the left of FIG. 7 shows a state before the door outer panel 3 is subjected to a side collision. The central view of FIG. 7 shows a state in which the lower end portion 25A of the open rod 25 is in contact with the inclined portion 38 of the rod pushing member 55 in response to a side collision. The figure on the right of FIG. 7 shows a state after receiving a side collision.

As shown in the left view of FIG. 7 and the center view of FIG. 7, when the vehicle door 1 is subjected to a side collision, the apparel infoce 8 is pushed inward in the vehicle width direction together with the door outer panel 3. As a result, since the mounting wall portion 57A of the fixing portion 57 is welded to the bottom surface portion 8C of the apparie infose 8, the rod push-up member 55 is pushed inward in the vehicle width direction integrally with the apparel informose 8.

As a result, the inclined portion 38 of the rod pushing member 55 pushed inward in the vehicle width direction comes into contact with the lower end portion 25A of the open rod 25 that has moved slightly downward due to the deformation of the door outer panel 3, and the open rod 25 The downward movement is blocked. That is, the downward rotation of the open lever 23 is prevented, the engagement between the door lock device 22 and the striker 31 is maintained, and the locked state of the vehicle door 1 is maintained.

Further, as shown in the central figure of FIG. 7, when the inclined portion 38 of the rod pushing member 55 abuts on the lower end portion 25A of the open rod 25 at the time of a side collision, the bottom surface of the door lower frame 13 and the apparinose 8 is formed. A gap of a predetermined distance (for example, about 5 mm to 20 mm) can be formed between the portion 8C and the portion 8C. As a result, after the lower end portion 25A of the open rod 25 comes into contact with the inclined portion 38 of the rod push-up member 55, the rod push-up member 55 and the apparinose 8 move integrally and smoothly inward in the vehicle width direction. Can be done.

Subsequently, as shown in the center view of FIG. 7 and the right figure of FIG. 7, the rod push-up member 55 and the apparie infose 8 are integrally provided via the door outer panel 3 and the apparel informose 8, and the vehicle width is further increased. Pushed inward in the direction. As a result, the lower end portion 25A of the open rod 25 that comes into contact with the inclined portion 38 of the rod pushing member 55 moves upward in the vehicle along the inclined portion 38 as the rod pushing member 55 moves inward in the vehicle width direction. Pushed up to the side.

As a result, the movement of the open rod 25 and the open lever 23 to the lower side of the vehicle is restricted, and in the event of a side collision, the opening of the vehicle door 51 can be prevented with a simple configuration. Further, at the time of a side collision, the inclined portion 38 of the rod push-up member 55, which is a fixed component fixed to the apparite informs 8 which is not involved in unlocking and locking the vehicle door 51, hits the lower end portion 25A of the open rod 25, so that the side surface It is easy to manage the collision mode of parts at the time of collision.

Further, since the flat plate-shaped inclined portion 38 of the rod pushing member 55 diagonally hits the open rod 25, not only the mounting position of the rod pushing member 55 with respect to the apparinose 8 varies, but also the mounting bracket 15 and the door inner panel 18 and the like. Variations in the degree of deformation of other parts and variations in the timing of deformation can be easily absorbed. Further, it is not necessary to attach a part to the open rod 25, and the space required for the open rod 25 to move in the vertical direction can be saved.

[Other Second Embodiment]
(B) Further, for example, in the vehicle door 1 according to the embodiment, when the bottom surface portion 8C of the apparinose 8 is located below the upper end edge 38B of the inclined portion 38 of the rod pushing member 26 in the vehicle vertical direction. May be as follows. For example, a "contact plate" made of a vertically long rectangular metal plate in front view extends upward from the upper end edge of the bottom surface portion 8C of the apparing informose 8 and the upper end edge 38B of the inclined portion 38 of the rod pushing member 26. It may be fixed by welding and joining by spot welding or the like so as to face the above. The width of the "contact plate" in the vehicle front-rear direction is preferably formed to be substantially equal to the width of the upper end edge 38B of the inclined portion 38 in the vehicle front-rear direction.

As a result, when the vehicle door 1 is subjected to a side collision, the apparite infose 8 is pushed inward in the vehicle width direction together with the door outer panel 3. As a result, the "contact plate" extending upward from the bottom surface portion 8C of the apparinose 8 abuts on the upper end edge 38B of the inclined portion 38 of the rod push-up member 26, and the rod push-up member 26 and the rod push-up member 26 The door lower frame 13 fixed to the door lower frame 13 can be integrally pushed inward in the vehicle width direction. Then, the inclined portion 38 of the rod pushing member 26 pushed inward in the vehicle width direction comes into contact with the lower end portion 25A of the open rod 25 that has moved slightly downward due to the deformation of the door outer panel 3, and is below the open rod 25. Movement to is blocked.

Subsequently, when the apparie infose 8 moves further inward in the vehicle width direction together with the door outer panel 3, the rod push-up member 26 and this rod pass through an "contact plate" extending upward from the bottom surface portion 8C of the apparel informose 8. The door lower frame 13 to which the push-up member 26 is fixed is integrally pushed further inward in the vehicle width direction. As a result, the lower end portion 25A of the open rod 25 that comes into contact with the inclined portion 38 of the rod pushing member 26 moves upward in the vehicle along the inclined portion 38 as the rod pushing member 26 moves inward in the vehicle width direction. Pushed up to the side.

As a result, the movement of the open rod 25 and the open lever 23 to the lower side of the vehicle is restricted, and it is possible to prevent the vehicle door 1 from opening with a simple configuration in the event of a side collision. Further, at the time of a side collision, the rod push-up member 26, which is a fixed component fixed to the door lower frame 13 which is not involved in unlocking and locking the vehicle door 1, extends upward from the bottom surface portion 8C of the apparinose 8. Since it hits the "plate", it is easy to manage the collision mode of parts in the event of a side collision.

[Other Third Embodiment]
(C) Further, for example, the vehicle door 1 and the vehicle door 51 according to the embodiment are the right front doors, but the door lock structures 11 and 53 are the left front door, the right rear door, and the left side. It can be applied to rear doors and the like.
