Description

[Detailed explanation of the idea] The present invention relates to a panel structure for an automobile.

Panel structures such as automobile doors and lids are generally formed by joining an outer panel and an inner panel, and around the panel,
A hemming structure is formed by folding and joining the outer panel onto the inner panel. In cases where the factory is remote or in knock-down production, such panel structures are stored with anti-corrosion oil applied after panel assembly is completed until they are assembled into the body. Rust preventive oil is removed using degreasing liquid before assembly. Removal of anti-corrosion oil is
This is done by submerging the panel in a degreasing liquid or by spraying the panel with a shower of degreasing liquid. In this case, the rust preventive oil that has entered the space between the inner panel and the outer panel is removed by the degreasing liquid that enters the space through the drain hole formed in the inner panel. However, in the hemming area, rust preventive oil also enters the small gap formed inside the folded part of the outer panel, and this rust preventive oil cannot be removed by the degreasing process described above. In the subsequent process, it oozes out from the above-mentioned voids, causing poor adhesion of the paint sealant. However, such a problem has not been pointed out to date.

The present invention was developed to solve these problems, and aims to provide an automobile panel structure that can effectively degrease the small voids formed inside the folded portion of the outer panel. purpose.

That is, the automotive panel structure of the present invention is characterized in that a notch is formed that communicates with a gap formed in at least one of the edge of the inner panel and the folded part of the outer panel, and inside the folded part of the outer panel. . What is the notch here?
The term is not limited to those that are formed to reach the edge, but also includes those that have an opening that leaves the edge. According to this configuration of the present invention, the degreasing liquid can sufficiently reach the void formed inside the folded part of the outer panel, so that the rust preventive oil is satisfactorily removed, and the remaining rust preventive oil oozes out afterwards. This eliminates the risk of poor paint adhesion.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, in FIGS. 1 and 2, a panel structure such as an automobile door panel or other lids is composed of an outer panel 1 and an inner panel 2. The edge portion 1a of the panel 1 is folded back onto the edge portion 2a of the inner panel 2 and joined by spot welding or the like to form a hemming portion. The inner panel 2 has a drainage hole 3 for removing rainwater that has entered the space between it and the outer panel 1.
is formed. Folded edge 1 of outer panel 1
A small void 4 is formed inside a due to the radius of curvature required for bending. In this example, cutouts 5 are formed at appropriate locations on the edge 2a of the inner panel 2. This notch 5 is
It reaches outside the edge of the folded edge 1a of the outer panel 1, and therefore the gap 4 is formed by this notch 5.
It will be exposed to the atmosphere through the Therefore, in the process of degreasing the panel structure, the degreasing liquid can sufficiently penetrate into the voids 4 to degrease the voids 4. This notch is preferably closed with a sealer in a subsequent step.

3 and 4 show another embodiment, in which a notch 15 reaching the gap 4 is formed in the folded edge 1a of the outer panel 1. The effect of this notch 15 is almost the same as that of the notch 5 in the previous example. Note that, as described above, the notches 5 and 15 are not limited to the shape shown in the drawings, but may be in the shape of an opening with a slight edge remaining.
