Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a module assembly structure for an automobile body.

[Conventional technology]

Conventionally, the floor and the body side of the vehicle body, together with the roof, the engine compartment, etc., have various strength members with a closed cross-section structure as skeleton members, and various panel materials are sequentially joined to this skeleton member to form a white body. After transferring to the painting process and assembly process, various functional parts and interior parts are finally assembled.

However, in the assembly and assembly process of this white body, assembling work is sequentially performed in each main line according to the above-mentioned procedure, so that the main line becomes longer, the equipment becomes larger accordingly, and it is expanded, which is disadvantageous in terms of cost. Becomes In addition, if the floor and body side are pre-configured, when assembling various parts inside the floor and inside the body side during the assembly process, the operator may enter the cabin or the body side opening of the body side. It has to be done manually, which requires a lot of labor and time. As a vehicle body structure for improving this, as shown in FIG. 6, the vehicle body is composed of a cowl lower part 180 and a cowl upper part 181.
Andamojuyuru 182 and Atsupamojuyuru 184 divided into two, these Andamojuyuru 182 and Atsupamojuyuru 1
A so-called vehicle body module assembly structure in which a vehicle body is constituted by connecting 84 and 84 is disclosed in Japanese Utility Model Publication No. 64-28372.

However, in this vehicle body module assembly structure, as shown in FIG. 7, the cowl upper portion 181 of the upper module 184 has a closed vertical cross section that is orthogonal to the vehicle width direction in order to improve rigidity. It has a sectional structure 186.

Therefore, when assembling the wiper link 188 to the cowl upper part 181, it is necessary to insert the wiper link 188 into the closed cross-section structure 186 from the working hole formed in the cowl upper part 181 in advance and to attach it. For this reason, there is a problem that the assembling of the wiper link becomes complicated and the assembling workability is not good.

[Problems to be solved by the device]

In consideration of the above facts, the present invention has an object to obtain a vehicle body module assembly structure capable of improving the workability of assembling the wiper link.

[Means for solving the problem]
