Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an automobile door and a method for assembling the same.

(Prior Art) Conventionally, an automobile door generally consists of a door body made up of an inner panel and an outer panel, and door interior parts such as a window regulator assembled to the door body. In other words, in the conventional door body, the door body is formed by joining the inch panel and the outer panel on three sides excluding the waist line, which makes it difficult to assemble the door interior parts to the door body. Attachment is done using the many working holes provided in the inner panel.

More specifically, in the door sacrificial process (the process of assembling door interior parts to the door body) as shown in Japanese Patent Publication No. 60-59101, each door interior part is inserted through a working hole opened in the inner panel. They were to be assembled at predetermined positions on the inner surface of the door body.

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

(1) The movement trajectory of the door interior parts is complicated because the door interior parts must be inserted through the working hole in the inner panel and positioned at a predetermined position, and the interior space of the door body is narrow, so it is difficult to assemble the door interior parts. The workability of the attachment work was poor, and it was also difficult to automate it.

(2) A large number of door interior parts had to be assembled within a limited time, requiring skilled workers.

(3) In particular, when assembling door lock mechanism parts such as door lock parts and key cylinders, it is necessary to connect the door lock part and each linking part with a connecting rod.
The work of connecting these parts in the interior space of the door body is complicated.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an automobile door and a method for assembling the same, which improves the ease of assembling door interior parts, particularly door lock mechanism parts, in door assembly.

(Means and effects for solving the problem) The present invention provides a method for assembling door lock mechanism parts by inserting them individually through work holes opened in the inner panel as in the conventional case. Based on the recognition that there is a limit to the improvement of workability, we have developed an automobile door with a skeleton placed between an inner panel and an outer panel, and a part of the skeleton that is assembled to the skeleton. Bracket for mounting the component door lock mechanism parts.

It consists of door lock mechanism parts assembled to the skeleton via the bracket.

The assembly method involves assembling the door lock mechanism parts to the door body in advance to the door lock mechanism parts mounting bracket that forms a part of the skeleton when it is assembled to the skeleton. By attaching the door lock mechanism parts mounting bracket to the skeleton, the door lock mechanism parts can be assembled to the skeleton.

With this configuration, it is possible to assemble the door lock mechanism components to the skeleton before assembling the inner panel or the outer panel. Therefore, it is possible to assemble door interior parts without having to worry about 1-inch panels or the like. In particular, since the door lock mechanism component mounting bracket constitutes a part of the skeleton when it is assembled to the skeleton, it is possible to maintain the rigidity of the skeleton. In addition, when assembling the door lock mechanism parts to the skeleton, it is done by assembling the bracket to which the door lock mechanism parts are already attached to the skeleton, so the process of attaching the door lock mechanism parts to the bracket and the bracket Since the process of assembling the parts into the skeleton can be carried out separately, it is possible to streamline each process.

(Example) An embodiment of the present invention will be described below based on the drawings.
