Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the body structure of an automobile, and particularly relates to the improvement of the door portion.

(Prior art) For example, in a four-door sedan as shown in Fig. 4,
As shown in the cross-sectional view in FIG. 5, the rear end 2a of the front door 2 and the rear end 3a of the rear door 3 are arranged on the outside of the center pillar 1 so that they are spaced apart from each other and butt each other. is normal.

By the way, in the event of a head-on collision of a car, etc., the front door 2 moves backward due to an external force, and the rear end 2a of the front door touches the rear door 3 as shown by the imaginary line.
If you go inside the door, there is a problem that both doors interfere with each other, making it impossible to open not only the front door 2 but also the rear door 3.

Therefore, conventionally, as disclosed in Japanese Utility Model Application No. 61-5265, for example, on the front outer surface of the center pillar 1 facing the rear end surface of the front door 2,
It has been proposed to provide a guide surface for guiding the rear end portion 2a of the front door 2 toward the outside of the vehicle when the front door 2 is moved backward, thereby preventing both doors from becoming deadlocked.

However, in the above-mentioned configuration, if there were variations in the relative positions of the center pillar 1 and the front door 2, there was a risk that the front door 2 would not move to the outside of the rear door 3.

(Purpose of the invention) Therefore, an object of the present invention is to provide a door structure that can reliably prevent both doors from locking without making any changes to the center pillar.

(Structure of the invention) The present invention is arranged so that the rear end of the front door and the front end of the rear door are spaced apart from each other and abut against each other on the vehicle outer side of the center pillar. In the door structure, a striker is provided on the center pillar for engaging a rear end portion of the front door to the center pillar by engaging a catch that is attached to the front door, the front door being moved backward by an external force. The present invention is characterized in that a guide portion for guiding the catch to the outside of the vehicle when the catch is engaged is formed so as to be inclined rearward toward the outside of the vehicle from the engagement position with the engagement member.

(Effects of the invention) According to the invention, when the front door attempts to move backward during a head-on collision, the catch provided on the front door is reliably engaged with the striker provided on the center pillar. Since the rear end of the front door is guided by the guide portion to the outside of the vehicle, it is possible to reliably prevent both doors from becoming locked. Furthermore, the object of the present invention is achieved by an extremely simple structure in which only a guide portion is formed on the striker provided on the center pillar, so it is extremely easy to change the design of an existing vehicle body.

(Example) An example of the present invention will be described in detail below with reference to FIGS. 1 and 2.

FIG. 1 is a sectional view showing an embodiment of the present invention corresponding to FIG. 5, and the same reference numerals are given to the same structural parts as in FIG. 5. 4 is center pillar 1
A door lock striker is a door lock striker that projects horizontally forward on the front end surface of the door.As is clear from Figure 2, it is formed by bending a metal bar with a circular cross section into a U-shape in the horizontal plane. A striker body 5 is provided, and the striker body 5 is fixed to the center pillar 1 via a flat bracket 6. The striker body 5 is connected to the front door 2.
When the striker body 5 is closed, it engages in the groove 7 formed in the front door 2, but at that time, the catch 8 installed at the back of the groove 7 engages the U of the striker body 5.
The front door 2 is engaged with the arm front portion 5a (indicated by hatching in FIG. 2) on the outside of the figure to lock the front door 2 in the closed position.

The catch 8 has a configuration known per se.
As shown in FIG. 3, a groove 15a into which the striker body 5 engages when the front door 2 is closed.
A latch base 15 is fixed to the rear end of the front door 2, and two pins 11 and 12 are provided on the latch base 15 in parallel with each other at a predetermined interval. It includes a pivoted fork 9 and a lever 10.

The fork 9, which is rotatably supported by the pin 11, is biased counterclockwise (in the direction of arrow A) in FIG. and the striker body 5
It has a groove 9b into which the portion 5a fits, and a wall 9c formed linearly between the protrusion 9a and the groove 9b. The fork 9 has a first position where it can lock the striker body 5 (the position indicated by a solid line in FIG. 3), and a second position where it can release the striker body 5.
The front door 2 is rotatably supported by a pin 11 between a position shown in FIG.

A lever 1 rotatably supported on a pin 12
0 is biased clockwise (in the direction of arrow B) in FIG.
a convex portion 10a that locks in the position; a lever portion 10b that is operated counterclockwise to release the lock;
When the front door 2 is open and the fork 9 is engaged with the edge of the latch base 15,
The lever part 10c locks the lever 10 in the position shown by the solid line in FIG. 3 when the lever 10 is locked in the position shown in FIG.

Next, the operation of the catch 8 will be explained. When the front door 2 is about to be closed, the striker body 5 gets stuck in the groove 15a of the latch base 15.
The portion 5a of the fork 9 comes into contact with the wall portion 9c of the fork 9, and the fork 9 rotates clockwise in FIG. The fork 9 comes into contact with the lever 10 due to the rotation of the lever 10.
By rotating counterclockwise against the biasing force of the spring, the fork 9 and the lever 10 are brought into the states shown by the dashed lines in FIG. 3, respectively. When the fork 9 is further rotated by the portion 5a of the striker body 5, the lever 10 slides on the outer peripheral surface of the fork 9 and returns to the position shown by the solid line in FIG. The front door 2 is locked in the first position shown by the solid line in FIG. 3, thereby keeping the front door 2 in the locked state. and the first
The fork 9 at the position locks the portion 5a of the striker body 5 near the outer side end of the groove 15a of the latch base 15 (inner part of the groove 15a).

When opening the front door 2, the lever 10 is rotated counterclockwise in FIG. 3 against the spring, thereby disengaging the lever 10 from the fork 9 and unlocking the front door 2. , the part of the striker body 5 is in the groove 1 of the latch base 15.
As it escapes from 5a, it returns to the second position (the position indicated by the broken line in FIG. 3) by the action of the spring.

This embodiment is characterized in that an inclined portion 5b is formed rearwardly from the portion 5a of the striker body 5 at which the catch 8 engages, and is inclined rearward toward the outside of the vehicle.

Such an inclined portion 5b is formed on the striker body 5, and when the front door 2 is locked in the closed position, the portion 5a of the striker body 5 is moved to the latch base 1 by the fork 9 of the catch 8.
5, the inclined portion 5b of the striker body 5 is locked near the outer end of the groove 15a of the latch base 15 when the front door 2 moves backward due to an impact such as a frontal collision. Since the catch 8 comes into contact with the outer side end of the vehicle, the catch 8 is guided by the inclined part 5b and moves along this inclined part 5b.
Before interfering with the front end 3a of the rear door 3, the rear end 2a of the front door 2 comes out further to the outside of the vehicle than the front end 3a of the rear door 3, and moves rearward as shown by the imaginary line. As a result, even if both doors are slightly deformed, a state in which both doors can be opened is obtained, and deadlock due to the backward movement of the front door 2 can be prevented.
