Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is applicable to an automobile in which the rear edge of the front door and the front edge of the rear door are arranged facing each other in the front and back outside the center pillar. It concerns the door structure.

(Prior art) Conventionally, in the event of a head-on collision of a car, the front door moves rearward and its trailing edge enters the front edge of the rear door, resulting in a deadlock situation in which both doors interfere and are difficult to open and close. To prevent this, for example, as shown in Japanese Utility Model Application Publication No. 61-5265, a guide is placed on the front outer surface of the center pillar to guide the rear end outward when the front door moves backward. Providing a sliding surface is practiced. However, since the center pillar is usually formed of a thin plate material, the sliding surface is easily deformed in the event of a car collision, and it may not be possible to guide the rear end of the front door to an extent that prevents the deadlock. . Furthermore, when the rear door moves forward due to a rear-end collision of the vehicle, the front edge of the rear door deforms to cover the outside of the rear edge of the front door, causing a deadlock problem.

(Purpose of the invention) This invention was made to solve the above problem, and in the event of a head-on collision or a rear-end collision, the trailing edge of the front door and the leading edge of the rear door An object of the present invention is to provide an automobile door structure that can effectively prevent the occurrence of a deadlock condition due to interference between parts.

(Structure of the invention) The present invention is an automobile door structure in which a rear edge of a front door and a front edge of a rear door are arranged opposite to each other on the outside of a center pillar, and the rear door is arranged opposite to each other on the outside of a center pillar. A hinge member for attaching to the front door is provided with a guide portion that slopes outward in the vehicle width direction from the front end toward the rear end, and a guide portion is provided on the rear wall of the front door so as to face the front door in a state close to the guide portion. A sloped guide surface is formed.

According to the above configuration, when the front door moves rearward in the event of a frontal collision of the automobile, and when the rear door and the hinge member move forward in the event of a rear-end collision of the automobile, the guide portion of the hinge member moves toward the rear end of the front door. The trailing edge of the front door abuts against the inclined guide surface, and the rear edge of the front door expands outward to prevent the door from becoming deadlocked.

(Embodiment) Fig. 1 shows a four-door sedan type automobile equipped with a door structure according to the present invention. are placed facing each other on the outside of the As shown in FIG. 2, the front door 1 includes an outer panel 4 and an inner panel 5.
A front door main body 6 consisting of a front door main body 6, a door sash 7 erected on the front door main body 6, and a door glass 8 supported along the door sash 7 so as to be movable up and down. A weather strip 9 is attached which is pressed against the front edge of the center pillar 3 when the front door 1 is closed. The rear door 2 also includes a rear door main body 12 consisting of an outer panel 10 and an inner panel 11, a door sash 13, a door glass 14, and a weather strip 15. 2
A pair of upper and lower door hinges 16 that support the door so that it can be opened and closed.
is installed.

The door hinge 16 includes a hinge metal fitting 17 bolted to the front wall of the rear door 2, a hinge bracket 18 bolted to the outer surface of the center pillar 3, and a hinge pin 19 that pivots the hinge metal fitting 17 to the hinge bracket 18. It is made up of. As shown in FIG. 2, a guide portion 20 is provided at the front end of the base plate of the hinge bracket 18 and is formed of a protrusion that slopes outward from the front end toward the rear end. Furthermore, an inclined guide surface 21 is formed on the rear wall of the front door 1 by slanting the central portion of the rear wall surface of the inner panel 5, so as to be close to and opposite to the guide section 20.

As described above, the hinge member consisting of the hinge bracket 18 constituting the door hinge 16 of the rear door 2 is provided with a guide portion 20 whose rear end is inclined outward in the vehicle width direction, and the rear wall portion of the front door 1 is In addition, since the inclined guide surface 21 is formed to face the guide portion 20 in close proximity to the guide portion 20, the inclined guide surface 21 of the front door 1 and the guide portion 20 of the hinge bracket 18 will come into contact with each other in the event of an automobile collision. By this, the rear edge 1 of the front door 1
As shown in FIG. 2, a can be moved outward to prevent interference between the doors 1 and 2. That is, when the front door 1 is forced rearward due to a head-on collision of a car, the inclined guide surface 21 is closed before the rear edge 1a of the front door 1 interferes with the front edge 2a of the rear door 2. comes into contact with the guide part 20,
Since the front door 1 moves along the slope, the rear edge 1a of the front door 1 is guided outward from the front edge 2a of the rear door 2, and both doors 1 and 2 are in a deadlock state. It is possible to prevent this from happening.

Further, when the rear door 2 is forced forward due to a rear-end collision of the automobile, the door hinge 16 moves forward together with the rear door 2, so that the front edge 2a of the rear door 2 is moved forward by the rear edge 1a of the front door 1. Before the guide part 20 interferes with the inclined guide surface 21
The rear edge 1a of the front door 1 can be moved outward to prevent interference between the doors 1 and 2. Moreover, in the above embodiment, since the guide portion 20 is formed by bending the substrate of the hinge bracket 18 made of thick plate material, the guide portion 20 has a predetermined rigidity and can withstand impact loads. The front door 1 above does not deform easily.
This has the advantage that the rear end of the can be reliably guided outward.

(Effects of the invention) As explained above, the invention provides a hinge member for attaching the rear door to the center pillar with a guide part that slopes outward from the front end toward the rear end, and Since an inclined guide surface is formed on the wall that faces the guide section in close proximity to the above-mentioned guide section, the rear edge of the front door can be moved outward with a simple structure in both a frontal collision and a rear-end collision. By opening the door, interference between the two doors can be reliably prevented, and a deadlock state can be prevented with a simple configuration.
