Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for joining a panel of a sub-assembly such as a dash module in which a steering member and an air conditioning unit are integrated with a panel on a vehicle body in an automobile.

[0002]

2. Description of the Related Art Conventionally, as a structure for joining a panel of the dash module to a vehicle body side panel, there is a structure shown in FIG. 4 (see Japanese Patent Laid-Open No. 59-206267). That is, one of the edge portions of the dash module side panel 1 or the vehicle body side panel 2 has a structure having a U-shaped groove 1a or 2a, and the groove is filled with an adhesive, and the edge of the other panel is filled therewith. The portion 2b or 1b is inserted, and the adhesive is hardened or combined with the bolt 3 to be joined.

[0003]

However, such a conventional panel joining structure has the following problems. When mounting the dash module on the vehicle body, it is difficult to align the edges of the panels to be joined because of low rigidity, and as a result, the edge of the panel cannot be inserted unless the groove width of the other panel is increased. Therefore, there is a problem in assembly accuracy.

Since the cross-sectional shape of the edge portion of the panel on the inserting side is substantially linear in the inserting direction, and even when fastening with a bolt, the fastening direction and the inserting direction are different,
After joining, it is easy to come off, and even if it does not come off, a gap is created and the sealing performance is likely to deteriorate. A separate structure for pressing the ends of the dash module side and vehicle body side insulators is required.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide an automobile panel joining structure that solves the above problems by devising the shape of the edge portion of the panel. And

[0006]

Therefore, the panel joining structure for an automobile according to the present invention is a structure for joining an end edge portion of a panel of a subassembly assembled to a vehicle body and an edge portion of a vehicle body side panel. , Bending at the end edge of the one panel in a direction upright with respect to the panel surface, and forming a hook portion formed by folding back the tip portion and a hole penetrating the inner and outer surfaces of the hook portion, The hook portion is bent and formed at an end edge portion of the other panel into a freely insertable concave groove portion, and portions adjacent to the hook portion and the concave groove portion of the two panels are polymerized to form a fastening portion that can be fastened. The hook portion is formed into the concave groove portion, and the hook portion is adhered to the concave groove portion with a sealing function by an adhesive filled therein, and the fastening portion is fastened and joined. To do.

Insulators are attached and fixed to the surfaces of the two panels, respectively, and a flange portion for pressing the end portion of the insulator of the other panel is provided at a portion extending from the fastening portion of at least one panel by joining the panels to each other. It may be formed.

[0008]

Since the edge of each panel is bent, the rigidity is improved, the positioning accuracy at the time of joining is improved, and the work efficiency is also improved. The adhesive enters the inside and outside of the hook through the holes of the hook, which improves the sealing and sound insulation properties, and the hook is inserted in the groove and the fastening direction is the same as the fastening direction. It is possible to reliably prevent the parts from coming off.

Further, in the structure in which the flange portion of one panel presses the end portion of the insulator on the other panel side, the sound insulation by the insulator can be further improved.
