Abstract

PURPOSE: To facilitate the wiring work in a back door, to reduce the cost of parts and the manhour, and to improve the rigidity. CONSTITUTION: In a back door structure of an automobile where a reinforcement is arranged between an outer panel and an inner panel of a back door fitted to the back face of the automobile body in an openable manner, a wall part 10a is formed on the reinforcement 10 so that an insert member 6 to be inserted in the back door is not interfered by a fitting piece 8 for mounting an outer parts.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back door structure for an automobile, which facilitates wiring work in the back door.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 4 and 5, a back door 1 of an automobile has a reinforcement 4 installed between an outer panel 2 and an inner panel 3. The back door 1 is attached to the body 5 via a hinge and a balancer (not shown). The back door 1 may be internally equipped with a wire harness 6 or a pipe or the like for power supply or signal for a wiper motor or the like. The wire harness 6 and the like are introduced into the back door 1 through an inner panel upper insertion hole (not shown) of the back door 1 and inserted through the back door 1 to be arranged.

By the way, in such a back door 1,
External parts such as the spoiler 7 may be attached via the screw 8 or the like.

For this reason, the wire harness 6 and the like are fixed to the reinforcement 4 by using the clamp 9 so that the screw 8 and the like do not interfere with the wire harness 6 and the like.

[0005]

However, the work for fixing the wire harness 6 and the like using the clamp 9 is required, and the work for moving and regulating the wire harness 6 and the like requires skill and the workability is poor. It was Moreover, since the clamp 9 is required, the number of parts is increased,
It was uneconomical.

The present invention solves the above problems and provides a back door structure for an automobile, which can easily perform wiring work inside the back door, can reduce the cost of parts and the number of work steps, and can improve the rigidity. The purpose is to do.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a vehicle in which a lean force is provided between an outer panel and an inner panel of a back door which is releasably attached to the rear surface of the vehicle body. In the back door structure of No. 1, the lean member has a wall portion that restricts the insertion member inserted into the back door so as not to be interfered with by the external component attachment fastener.

[0008]

[Operation] For example, when wiring the wire harness to the wiper motor mounting portion of the back door, the wire harness is guided along the wall of the reinforcement and does not interfere with the external component mounting fastener.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

1 to 3, the same parts as those of FIGS. 4 and 5 are designated by the same reference numerals, and the description of the same parts will be omitted. 1 to 3, the back door 1 is composed of an outer panel 2 and an inner panel 3, and a lean reinforcement 10 is provided between the outer panel 2 and the inner panel 3.

The lean reinforcement 10 includes screws 8 and the like (fasteners) for fastening external parts such as the spoiler 7 and the like.
In the portion that protrudes inward, a wall portion 10a that partitions off the protruding portion 8a such as the screw 8 is formed by curving the middle of the lean reinforcement 10. This prevents the screw 8 or the like from interfering with the wire harness 6 or the like when the wire harness 6 or the like (insertion member) is inserted into the back door 1.

According to the back door of the automobile having the above-mentioned structure, when the wire harness 6 and the like are inserted into the back door 1, the screws 8 and the like for fixing the external parts such as the spoiler 7 and the like project from the outer panel 2 to the inside. In part, it is guided along the wall 10a. Therefore, the screw 8 or the like does not interfere with the wire harness 6 or the like.

[0013]

As described above, according to the backdoor structure for an automobile according to the present invention, a lean force is provided between the outer panel and the inner panel of the backdoor which is releasably attached to the rear surface of the vehicle body of the automobile. In the backdoor structure of the arranged vehicle, since the insertion member to be inserted into the backdoor is formed with a wall portion for restricting the reinforcement member so as not to be interfered with by the external component attachment fastener, the wire When inserting the harness or the like into the back door, the parts such as the screws protruding inside the back door do not interfere. Since it is not necessary to use a clamp or the like as in the conventional case, the cost of parts and the number of steps can be reduced. In addition, since it is not necessary for the worker to move or regulate the wire harness or the like, skill is required, so that productivity can be improved. Since the rigidity of the external component mounting portion can be improved, the outer panel can be prevented from being deformed.
