Description

TECHNICAL FIELD The present invention relates to an automobile door and a method for assembling the same.

(Prior Art) Conventionally, an automobile door is generally composed of a door body including an inner panel and an outer panel, and a door interior component such as a window regulator attached to the door body. That is, in the conventional one, the door body is
It is formed by joining the three sides of the inner panel and the outer panel, excluding the waistline, so that when assembling the door interior parts to the door body, many working holes are provided in the inner panel. It is designed to be used.

More specifically, in the door fitting process (the process of assembling the door interior parts to the door body) found in Japanese Patent Publication No. 60-59101, insert each door interior part from the work hole opened in the inner panel. It was supposed to be attached to each predetermined position on the inner surface of the door body.

(Problems to be Solved by the Present Invention) Therefore, the conventional door assembly work has the following problems.

(1) Since the door interior parts must be inserted from the work holes of the inner panel and positioned at predetermined positions, the movement path of the door interior parts is complicated, and the internal space of the door body is narrow, so that the combination of the door interior parts is assembled. Workability in attaching work was poor, and its automation was also difficult.

(2) A large number of door interior parts must be assembled within a limited time, and a skilled worker is required.

(3) In particular, in assembling the door lock mechanism parts such as the door lock parts and the key cylinder, it is necessary to connect the door lock part and each linking part with a connecting rod. The work of connecting them was complicated.

Therefore, an object of the present invention is to provide an automobile door and an assembling method thereof for improving the workability of assembling door interior parts, particularly door lock mechanism parts in door assembly.

(Means and Actions for Solving Problems) According to the present invention, when the door lock mechanism components are individually inserted from the working holes opened in the inner panel to assemble these components, as in the conventional case. Based on the recognition that there is a limit to the improvement of workability, a skeleton that is placed by sandwiching an automobile door between an inner panel and an outer panel, and a part of the skeleton that is assembled to the skeleton A bracket for mounting the constituent parts of the door lock mechanism,
The door lock mechanism is assembled to the skeleton through the bracket. Then, as the assembling method, the door lock mechanism parts are assembled to the door body in advance when the door lock mechanism parts mounting bracket that constitutes a part of the skeleton when assembled to the skeleton is equipped with the door lock mechanism parts. Installed,
By assembling the door lock mechanism component mounting bracket to the skeleton, the door lock mechanism components are assembled to the skeleton.

With such a structure, the door lock mechanism component can be assembled to the skeleton before the inner panel or the outer panel is assembled. Therefore, the door interior component assembling work can be performed without being bothered by the inner panel and the like. In particular, since the door lock mechanism component mounting bracket constitutes a part of the bracket when assembled to the skeleton, it is possible to maintain the rigidity of the skeleton. Also, assembling the door lock mechanism parts to the skeleton is performed by assembling the bracket to which the door lock mechanism parts are already attached to the skeleton. Since it can be performed separately from the step of assembling the skeleton, each step can be integrated.
