It was inconvenient and the installation work was very bad.

Further, since only a small working hole 4 is provided in the inner panel 1 in consideration of its rigidity, the inner panel 1 becomes considerably bulky and becomes a bottleneck in reducing the weight of an automobile door structure. Was.

When attaching the glass 6 to the guide rail 8, the operator holds the glass 6 with one hand, inserts the glass 6 from the upper opening 5 of the door bag section 3, and uses the other hand to hold the lower end of the glass 6. Then, a driver is inserted into the through hole k, and the opening x of the glass mounting portion 8b and the lower end mounting portion 6 of the door glass 6 are inserted.
The opening work y using a screw, etc., together with the opening y in a, is a blind operation.
From this point, workability is also deteriorated.

Furthermore, the guide rail 8 has a structure mounted on the inner panel via the rail bracket 11, and is mounted so as to float on the inner panel, thereby substantially contributing to an increase in rigidity of the door structure. I didn't.

Further, since the door speaker P is mounted on the inner panel C, a speaker mounting portion is necessarily provided at the edge of the opening 18 of the inner panel 1 in order to mount the door speaker P. Therefore, the area of the opening 18 is at most one size larger than the external dimensions of the door speaker P, and it is difficult to reduce the weight of the door body A.

In view of the above, a first object of the present invention is to provide a door structure for an automobile which achieves both a reduction in weight and an improvement in workability for mounting a glass elevating mechanism and the like.

Further, since the door speaker 60 is sub-assembled on the back surface of the door trim 50, the mounting operation is much more difficult than the conventional operation of inserting the hand through the working hole and mounting it on the inner panel 21. In addition, individual parts such as performance tests can be checked at the sub-assembly stage, and the troublesome parts checking work performed after the completion of the vehicle door can be eliminated.

Further, since the door speaker 60 is covered by the rib 53 and the molded sheet 62 surrounding the door speaker 60, sound leakage can be reduced as much as possible. Since it is possible to follow the shape change of the speaker 60 by deforming or the like, it is not necessary to prepare a different shape for each change of the door speaker 60 type.

According to the third aspect of the present invention, the lower end of the upper trim is formed in a bifurcated shape, and the upper end of the lower trim is inserted into the bifurcated portion. As a configuration in which the lower end and the upper end of the lower trim are superimposed, the upper trim and the lower trim adopt a configuration in which the upper end of the lower trim is inserted into the forked portion of the upper trim, so the lower trim is attached to the inner panel. After installing, when installing the upper trim, just insert the forked part into the upper end of the lower trim,
With the lower end of the upper trim and the upper end of the lower trim trimmed up, the lower end of the upper trim can be attached, and the upper end or side end of the upper panel can be attached to the inner panel. .

According to the automobile door structure of the present invention as described in claims 4 and 5, similarly to the above-mentioned invention, the inner panel is provided with the guide rail or the reinforcing plate bridged by the opening hole. Since the inner panel is connected, the rigidity of the inner panel also controls the guide rail and the reinforcing plate, and the opening hole can secure a very large opening area.

For this reason, the mounting operation is performed by inserting a glass elevating mechanism or glass from the large opening hole, so that the mounting workability is greatly improved, and the guide rail is used as a reinforce member. This contributes to the weight reduction of the inner panel and thus the door structure itself.

Further, according to the present invention as set forth in claim 4 or 5, the door speaker is sub-assembled on the back surface of the door trim. Compared with the work of attaching to the panel, it becomes very simple, and furthermore, it is possible to check individual parts such as performance tests at the sub-assembly stage, and it is possible to eliminate the troublesome parts check work performed after the door is completed.

Further, since the door speaker is covered by the rib and the molding sheet surrounding the door speaker, sound leakage can be reduced as much as possible. Therefore, it is not necessary to prepare a door speaker having a different shape every time the door speaker type is changed.
