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 Figure 3,
As shown in the cross-sectional view in FIG. 4, the rear end 2a of the front door 2 and the rear end 3a of the rear door 3 are disposed on the vehicle outer side of the center pillar 1 so that they are spaced apart from each other and abut against 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 configuration, the center pillar 1
If variations occur in the relative positions of the front door 2 and the front door 2, there is a risk that the front door 2 will not move outward from the rear door 3.

(Purpose of the invention) An object of the invention is to provide a door structure that can more reliably prevent both doors from becoming deadlocked than conventional ones.

(Structure of the invention) The present invention provides a support member that supports the rear door on the vehicle body with a receiving surface facing forward, and a receiving surface that contacts the said receiving surface at the rear end of the front door when the front door is moved backward by an external force. The present invention is characterized in that an abutting member is provided opposite to the receiving surface so that the rear end of the front door and the front end of the rear door can be kept in a spaced relationship by being in contact with each other.

(Effects of the invention) According to the invention, even if the front door attempts to move backward during a head-on collision, the contact member provided at the rear end of the front door will come into contact with the receiving surface provided on the support member of the rear door. Since the rear end of the front door and the front end of the rear door are kept in a spaced relationship because they are in contact with each other, deadlock of both doors can be prevented.

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

FIG. 1 is a sectional view showing an embodiment of the present invention corresponding to FIG. 4, and the same reference numerals are given to the same structural parts as in FIG. 4. Further, FIG. 2 is an exploded perspective view of the main parts of FIG. 1. In the figure, reference numeral 4 denotes a hinge plate bolted to the center pillar 1 in order to pivotally support the rear door 3 to the center pillar 1, and a bracket 6 bolted to the front of the rear door 3 together with a reinforcing plate 5 is attached to the hinge pin 7. is pivotally supported at the rear of the hinge plate 4 by. The front end of the hinge plate 4 is bent at a substantially right angle to form a receiving surface 4a facing forward. On the other hand, on the rear surface of the front door 2, a contact member 8 having a contact surface 8a at a position opposite to the receiving surface 4a is bolted together with a reinforcing plate 9.
The receiving surface 4a and the abutting surface 8a face each other with a slight distance therebetween.

With this configuration, when the front door 2 attempts to move backward due to a head-on collision, etc., the contact member 8
Since the abutment surface 8a abuts against the receiving surface 4a of the hinge plate 4 and prevents the front door 2 from moving backward, the distance between the rear end 2a of the front door 2 and the front end 3a of the rear door 3 is maintained; As a result, it is possible to prevent both doors from becoming deadlocked.

Claims (1)

[Claim for Utility Model Registration] In a vehicle body structure in which 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, a support member that supports the rear door on the vehicle body has a front A receiving surface facing the front door is provided at the rear end of the front door, and when the front door is moved backward due to an external force, the receiving surface contacts the receiving surface to connect the rear end of the front door and the front end of the rear door. A door structure for an automobile, characterized in that an abutment member that can be maintained in a spaced-apart relationship is provided opposite the receiving surface.
