The outer surface in the vehicle width direction, which constitutes approximately the lower half of the vehicle door 1, is constituted by a door outer panel 3 made of a metal plate. A door sash 5 is provided on the upper part of the door outer panel 3, and the upper end of the door outer panel 3 and the door sash 5 form a window part 7 that can be opened and closed by a window glass 6 made of tempered glass.

A door lock structure 11 is disposed below the rear sash 5A on the rear side of the door sash 5. The door lock structure 11 locks to a center pillar (not shown) when the vehicle door 1 is closed. In addition, on the inner surface of the door outer panel 3 in the vehicle width direction, an upper reinforcement 8 (reinforcing member) with a hat-shaped cross section (see Fig. 2) and a lower reinforcement 9 with a band plate shape are arranged vertically on the inside surface of the door outer panel 3 in the vehicle width direction. It is provided so as to extend over almost the entire width of the vehicle door 1 along the width direction (vehicle longitudinal direction). Here, the upper reinforcement 8 functions as an example of a reinforcing member.

As shown in FIGS. 1 and 2, the upper reinforcement 8 having a hat-shaped cross section is a reinforcing member having a convex shape toward the inside in the vehicle width direction, and is welded to the door outer panel 3 by spot welding or the like at each flange 8A. It is joined. The end portion of the upper reinforcement 8 on the vehicle rear side is disposed at a position facing the lower portion of the door lock structure 11 in the vehicle width direction. Further, the lower reinforcement 9 is arranged below the upper reinforcement 8, inclined downward toward the rear of the vehicle, and welded to the door outer panel 3 by spot welding or the like. Further, the upper end portion of a metal door lower frame 13 is connected to the lower portion of the rear sash 5A.

As shown in FIGS. 2 and 3, the door lower frame 13 has a substantially U-shaped cross section that opens toward the front of the vehicle, and is made of rubber (not shown) with a substantially U-shaped cross section. A glass run is fitted inside to support the rear edge of the window glass 6 in a vertically slidable manner. One end portion 15A of a mounting bracket 15 made of a metal plate formed into a substantially L-shape in plan view of the vehicle is welded (fixed) to the bottom surface portion 13A of the lower end of the door lower frame 13 on the rear side of the vehicle by spot welding or the like. ) has been done. In FIG. 2, welding locations are indicated by x marks. A nut 16 is welded to the other end 15B of the mounting bracket 15 on the outer surface in the vehicle width direction, and is attached to a door inner panel 18 made of a metal plate that constitutes the inner surface in the vehicle width direction of about the lower half of the vehicle door 1. It is fixed with bolts.

As shown in FIGS. 2 and 3, the door lock structure 11 includes a door handle 21 disposed on the door outer panel 3, and a door lock device disposed below the door handle 21 and closer to the vehicle interior than the door lower frame 13. 22, an open lever 23 that unlocks the door lock device 22, a bar-shaped open rod 25 that connects the open lever 23 and the door handle 21, and a lower end portion 25A of the open rod 25 facing the lower side of the vehicle. A metal rod push-up member 26 is provided.

Further, a key cylinder 27 is incorporated in the end of the door handle 21 on the vehicle rear side. The door lock structure 11 includes a bar-shaped key rod 28 that connects the key cylinder 27 and the upper end of the door lock device 22 and rotates in conjunction with the rotation performed by inserting a key (not shown) into the key cylinder 27. ing. By inserting a key (not shown) into the key cylinder 27 and rotating it counterclockwise, for example, the key rod 28 is rotated and the vehicle door 1 is locked.

The door lock device 22 engages with a substantially U-shaped striker 31 having both ends fixed to a center pillar (not shown) when the vehicle door 1 is closed, thereby locking the vehicle door 1 in a fully closed position. It is composed of Further, the door lock device 22 is disposed between the door lower frame 13 and the door inner panel 18, and is formed so that about half of the front side of the vehicle facing the door lower frame 13 is thinner. A gap of distance L1 is formed between the door lock device 22 and the door lower frame 13 in the vehicle width direction.

The open rod 25 is a rod-shaped member that extends substantially in the vertical direction of the vehicle, and has an upper end that is the tip of a support rib 21A that protrudes inward in the vehicle width direction from the upper end edge of the door handle 21 on the vehicle front side than the key cylinder 27. is rotatably connected to. The open rod 25 passes between the door lower frame 13 and the door outer panel 3 so that its lower end is located closer to the vehicle rear side than the bottom surface 13A of the door lower frame 13 on the vehicle rear side. , after being bent inward in the vehicle width direction, it is further bent toward the lower side of the vehicle.

A ring-shaped elastic member 32 made of synthetic rubber or the like is fitted into the portion of the open rod 25 that is bent toward the lower side of the vehicle, and is formed at the outer end of the open lever 23 in the vehicle width direction. It is inserted into a through hole (not shown) from above the vehicle. As a result, the corner portion of the open rod 25 bent toward the lower side of the vehicle abuts and is connected to the outer end portion of the open lever 23 in the vehicle width direction via the ring-shaped elastic member 32. Further, the lower end portion 25A of the open rod 25 projects from the outer end of the open lever 23 in the vehicle width direction toward the vehicle lower side by a predetermined length.

As a result, when the door handle 21 is pulled up from the outside of the vehicle (rotated in the direction of arrow 35), the open rod 25 moves toward the lower side of the vehicle (in the direction of arrow 36), and the open lever 23 is moved. Rotate it downward. Thereby, the engagement between the door lock device 22 and the striker 31 is released, and the vehicle door 1 is unlocked.

The open lever 23 protrudes outward in the vehicle width direction from the rear end of the door lock device 22, passing near the rear side of the vehicle with respect to the bottom surface 13A of the door lower frame 13, and extends in the unlocking direction (direction of arrow 36). It has a plate-shaped main body 23A that is swingably supported. The open lever 23 also includes a flat plate portion 23B that protrudes from the outer end in the vehicle width direction of the main body portion 23A in a direction (vehicle rearward direction in FIG. 3) that intersects the lock release direction (arrow 36 direction). have.

A through hole (not shown) is formed in the flat plate portion 23B, through which a portion of the open rod 25 bent toward the vehicle lower side is inserted. The main body 23A of the open lever 23 is biased to rotate upwardly of the vehicle by a biasing member such as a torsion coil spring (not shown), and the open rod 25 is moved upwardly of the vehicle via the elastic member 32. Force it to move to the side.

The rod push-up member 26 has a flat plate-like inclined portion 38 that slopes obliquely upward on the door outer panel 3 side from a position below the lower end portion 25A of the open rod 25 that moves toward the vehicle lower side when the door handle 21 is opened. have. The inclined portion 38 has a substantially rectangular shape and is arranged so as to protrude from the bottom surface portion 13A of the door lower frame 13 toward the rear of the vehicle. It is located near the bracket 15. Incidentally, it is preferable that the inclined portion 38 be provided so as to be inclined obliquely 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 side of the door outer panel 3 is located above the lower end portion 25A of the open rod 25 in the vehicle vertical direction, and the upper reinforcement 8 has a hat-shaped cross section. It is arranged so as to face a bottom surface portion 8C that connects a pair of vertical wall portions 8B. Preferably, the upper end edge 38B of the inclined portion 38 in the vehicle vertical direction is disposed so as to face the center portion of the bottom surface portion 8C of the upper reinforcement 8 in the vehicle vertical direction. Further, the upper end edge 38B of the inclined portion 38 in the vehicle vertical direction and the bottom surface portion 8C of the upper reinforcement 8 are separated by a predetermined distance.

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

Therefore, the rod push-up member 26 is formed into an L-shape in side view by the inclined part 38 and the fixed part 39, and there is a gap of a distance L1 between the door lock device 22 and the fixed part 39 in the vehicle width direction. is formed. In addition, the rod push-up member 26 is provided with a pair of reinforcing ribs 41 that are recessed upward, respectively, at positions that approximately divide the ridge line formed by the inclined portion 38 and the fixed portion 39 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 push-up member 26 is the distance L2 in the vehicle width direction 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, approximately 5 mm to 20 mm). As a result, as will be described later, when the inclined portion 38 of the rod push-up member 26 comes into contact with the lower end portion 25A of the open rod 25 in a side collision, a predetermined gap is formed between the door lock device 22 and the door lower frame 13. The structure is such that a gap of a distance (for example, about 5 mm to 20 mm) can be formed (see the center diagram of FIG. 4).

Next, an example of deformation of the door lock structure 11 when the vehicle door 1 configured as described above receives a side collision will be described based on FIG. 4. The left diagram in FIG. 4 shows the state before the door outer panel 3 is subjected to a side collision. The center diagram in 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 push-up member 26 due to a side collision. The right diagram in FIG. 4 shows the state after 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 upper reinforcement 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 upper reinforcement 8 comes into contact with the upper 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 moved. Push it inward in the width direction of the vehicle.

As a result, the inclined portion 38 of the rod push-up 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. Downward movement is prevented. 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 center diagram of FIG. 4 and the right diagram of FIG. The door lower 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 in contact with the inclined portion 38 of the rod pushing up member 26 moves upward in the vehicle along the inclined portion 38 as the rod pushing up member 26 moves inward in the vehicle width direction. Pushed to the side.

This restricts the movement of the open rod 25 and the open lever 23 toward the lower side of the vehicle, making it possible to prevent the vehicle door 1 from opening with a simple configuration in the event of a side collision. In addition, in the event of a side collision, the rod push-up member 26, which is a fixed part fixed to the door lower frame 13 that is not involved in unlocking or locking the vehicle door 1, hits the upper reinforcement 8 attached to the door outer panel 3. It is easy to manage the collision mode of parts during a collision.

Further, since the flat inclined portion 38 of the rod push-up member 26 obliquely contacts the open rod 25, not only the mounting position of the rod push-up member 26 with respect to the door lower frame 13 may vary, but also the mounting bracket 15 and the door inner panel 18 may It is also possible to easily absorb variations in the degree of deformation of other parts, such as variations in the timing of deformation, etc. Further, there is no need to attach any parts 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 embodiments, and various changes and improvements can be made without departing from the gist of the present invention. , addition, and deletion are possible. In the following description, the same reference numerals as the vehicle door 1 etc. according to the embodiment shown in FIGS. 1 to 4 above indicate the same or equivalent parts as the vehicle door 1 etc. 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 based on 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 push-up member 55 is provided instead of the rod push-up member 26.

Specifically, the rod push-up member 55 is positioned below the lower end portion 25A of the open rod 25 that moves toward the lower side of the vehicle (in the direction of arrow 36) when the door handle 21 is opened (rotated in the direction of arrow 35). It has a flat plate-shaped slope part 38 that slopes obliquely upward from the position toward the door outer panel 3 side. The inclined portion 38 is formed in a substantially rectangular shape, and is located near the bottom portion 13A of the door lower frame 13 with the side edge on the front side of the vehicle spaced apart from the bottom portion 13A of the door lower frame 13. It is arranged to intersect with 13A. Further, a lower end edge 38A of the inclined portion 38 in the vehicle vertical direction is located near the mounting bracket 15 attached to the lower end portion of the door lower frame 13.

Further, an upper end edge 38B of the inclined portion 38 in the vehicle vertical direction, that is, an upper end edge 38B on the side of the door outer panel 3 is located higher than the lower end portion 25A of the open rod 25 in the vehicle vertical direction. The rod push-up member 55 extends outward in the vehicle width direction from the upper end edge 38B of the inclined portion 38 over the entire width to the bottom surface portion 8C of the upper reinforcement 8 (reinforcement member), and further extends to the outer end in the vehicle width direction. It has a fixing part (second extending part) 57 extending substantially perpendicularly downward from the edge along the bottom surface part 8C over the entire width and having an inverted L-shape in side view. Here, the fixing part 57 functions as an example of the second extending part. The upper reinforcement 8 functions as an example of a door member.

A mounting wall portion 57A extending substantially perpendicularly downward from the outer edge in the vehicle width direction of the fixed portion (second extending portion) 57 along the bottom portion 8C is attached to the bottom portion 8C of the upper reinforcement 8 (reinforcing member). It is welded and fixed by spot welding etc. In FIG. 6, welding locations of the fixing portion (second extension portion) 57 are indicated by x marks. As a result, when the vehicle door 51 receives a side collision, the door outer panel 3 and the upper reinforcement 8 move inward in the vehicle width direction, and the upper reinforcement 8 and the rod push-up member 55 integrally move inward in the vehicle width direction. Moving.

Further, as shown in FIG. 5, a 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 push-up member 55 is the distance L2 between the door lower frame 13 and the bottom surface portion 8C of the upper reinforcement 8. The distance is set to be shorter than the distance L3 in the vehicle width direction by a predetermined length (for example, approximately 5 mm to 20 mm). As a result, as will be described later, when the inclined portion 38 of the rod push-up member 55 abuts the lower end portion 25A of the open rod 25 during a side collision, the gap between the door lower frame 13 and the bottom surface portion 8C of the upper reinforcement 8 A gap of a predetermined distance (for example, about 5 mm to 20 mm) can be formed between the holes (see the center diagram of FIG. 7).

Next, an example of deformation of the door lock structure 53 when the vehicle door 51 configured as described above receives a side collision will be described with reference to FIG. 7. The left view in FIG. 7 shows the state before the door outer panel 3 is subjected to a side collision. The center diagram in 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 push-up member 55 due to a side collision. The right diagram in FIG. 7 shows the state after a side collision.

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

As a result, the inclined portion 38 of the rod push-up member 55 pushed inward in the vehicle width direction comes into contact with the lower end portion 25A of the open rod 25, which has moved slightly downward due to the deformation of the door outer panel 3, and the open rod 25 Downward movement is prevented. 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 center diagram of FIG. 7, when the inclined portion 38 of the rod push-up member 55 abuts the lower end portion 25A of the open rod 25 during a side collision, the bottom surface of the door lower frame 13 and the upper reinforcement 8 A gap of a predetermined distance (for example, approximately 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 upper reinforcement 8 integrally move further inward in the vehicle width direction smoothly. I can do it.

Subsequently, as shown in the center diagram of FIG. 7 and the right diagram of FIG. pushed inward. As a result, the lower end portion 25A of the open rod 25 that has come into contact with the inclined portion 38 of the rod pushing up member 55 moves upward in the vehicle along the inclined portion 38 as the rod pushing up member 55 moves inward in the vehicle width direction. Pushed to the side.

This restricts the movement of the open rod 25 and the open lever 23 toward the lower side of the vehicle, making it possible to prevent the vehicle door 51 from opening with a simple configuration in the event of a side collision. Further, in the event of a side collision, the inclined portion 38 of the rod push-up member 55, which is a fixed part fixed to the upper reinforcement 8 that is not involved in unlocking or locking the vehicle door 51, hits the lower end portion 25A of the open rod 25, so that the side It is easy to manage the collision mode of parts during a collision.

In addition, since the flat inclined portion 38 of the rod push-up member 55 obliquely contacts the open rod 25, not only the mounting position of the rod push-up member 55 with respect to the upper reinforcement 8 may vary, but also the mounting bracket 15, door inner panel 18, etc. It is also possible to easily absorb variations in the degree of deformation of other parts, variations in the timing of deformation, etc. Further, there is no need to attach any parts 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) Also, for example, in the vehicle door 1 according to the embodiment, the bottom surface portion 8C of the upper reinforcement 8 is located lower than the upper edge 38B of the inclined portion 38 of the rod push-up member 26 in the vehicle vertical direction. You can do the following: For example, a "contact plate" made of a metal plate having a vertically elongated rectangular shape when viewed from the front is arranged so as to extend upward from the upper edge of the bottom surface part 8C of the upper reinforcement 8, and the upper edge 38B of the inclined part 38 of the rod push-up member 26. They may be welded and fixed by spot welding or the like so that they face each other. It is preferable that the width of the "contact plate" in the vehicle longitudinal direction is approximately equal to the width of the upper end edge 38B of the inclined portion 38 in the vehicle longitudinal direction.

Thereby, when the vehicle door 1 receives a side collision, the upper reinforcement 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 8C of the upper reinforcement 8 comes into contact with the upper edge 38B of the inclined part 38 of the rod push-up member 26, and the rod push-up member 26 and this rod push-up member 26 The door lower frame 13 to which is fixed can be integrally pushed inward in the vehicle width direction. Then, the inclined portion 38 of the rod push-up 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 lower end portion 25A of the open rod 25 moves downward. Movement to is prevented.

Subsequently, when the upper reinforcement 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 are The door lower frame 13 to which the push-up member 26 is fixed is further pushed inward in the vehicle width direction as a whole. As a result, the lower end portion 25A of the open rod 25 in contact with the inclined portion 38 of the rod pushing up member 26 moves upward in the vehicle along the inclined portion 38 as the rod pushing up member 26 moves inward in the vehicle width direction. Pushed to the side.

This restricts the movement of the open rod 25 and the open lever 23 toward the lower side of the vehicle, making it possible to prevent the vehicle door 1 from opening with a simple configuration in the event of a side collision. In addition, in the event of a side collision, the rod push-up member 26, which is a fixed part fixed to the door lower frame 13 that is not involved in unlocking or locking the vehicle door 1, is brought into contact with the This makes it easier to manage the collision mode of the parts in the event of a side collision.
