本発明は自動車の内装板とその縁部を覆って曲げた外装
板とからなるヘミング部の構造と、その形成方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a hemming section of an automobile, which is composed of an interior panel and an exterior panel bent to cover the edges thereof, and a method for forming the hemming section.

特開昭５９−１２８０８４号公報に開示されている。Automobile doors and trunk lids consist of an exterior panel and an interior panel, and the structure is called a hemming structure, in which the exterior panel is bent to cover the edge of the interior panel. The exterior and interior panels are welded together and filled with adhesive to strengthen the connection, prevent rainwater from entering, and prevent rust. Such a structure is disclosed in, for example, Japanese Patent Laid-Open No. 128084/1984.
従来の自動車車体ヘミング部の構造で、内装板と外装板

外装板を歪ませることがある。特に接着剤が肉厚に塗布
されている部分では、内部応力が増大することにより部
分的な剥がれが生じ、そこに水分が浸透して防錆性が低
下することになる。In the conventional structure of the hemming part of an automobile body, the gap between the interior and exterior panels is filled with thermosetting resin (e.g., epoxy resin) adhesive, and the bond between the interior and exterior panels is strong. Although this is preferable, the adhesive force is too strong, so
It may distort the exterior plate. Particularly in areas where the adhesive is applied thickly, internal stress increases, causing partial peeling, and moisture infiltrates there, resulting in a decrease in rust prevention.

溶接部分が腐食しやすいという欠点がある。Furthermore, conventional hemming structures in which the gap between the interior and exterior panels is filled with a thermoplastic resin such as vinyl chloride adhesive or butyl rubber adhesive have the disadvantage of weak adhesive strength. . In particular, vinyl chloride-based adhesives have low strength at high temperatures, and have the disadvantage that the spot welded parts are susceptible to corrosion due to the hydrochloric acid gas generated when the vinyl chloride decomposes due to the heat of spot welding.

である。The present invention eliminates the above-mentioned drawbacks of the conventional hemming part structure of an automobile body, and provides a hemming part structure with excellent adhesive strength, good sealing performance, and good rust prevention properties, and a method for forming the hemming part.

。The structure of the hemming portion of an automobile body according to the present invention, which solves the above-mentioned problems, will be explained with reference to FIG. 1, which corresponds to an embodiment. As shown in the figure, the hemming portion consists of an interior plate 2 and an exterior plate l having a bent portion 1a that covers an edge 2a of the interior plate 2. The gap between the interior panel 2 and the exterior panel 1 is filled with a thermosetting resin layer 4 and a thermoplastic resin layer 5.

２ａを覆うように外装板ｌを、同図（ｂ）に示すように
折り曲げる。そして、少なくとも該熱硬化性樹脂の層４
を加熱して硬化する。Further, a method of forming the structure of the hemming portion of an automobile body according to the present invention will be explained with reference to FIG. As shown in Figure (a), a thermosetting resin layer 4 and a thermoplastic resin layer 5 are applied to the exterior board 1 or the interior board 2. Next, the exterior board 1 is coated so as to cover the edge 2a of the interior board 2. The plate 1 is bent as shown in the same figure (b). At least the thermosetting resin layer 4
Heat and harden.
熱硬化性樹脂の層４と熱可塑性樹脂の層５とにより内装

を保持することができる。The thermosetting resin layer 4 and the thermoplastic resin layer 5 fill the gap between the interior panel 2 and the exterior panel 1, preventing moisture from penetrating, resulting in excellent rust prevention. Compared to the case where only thermosetting resin is filled, the amount of thermosetting resin is smaller, and the thermoplastic resin that is filled is flexible, so the thermosetting resin does not distort the exterior plate. Since the adhesive resin is also filled, the adhesive strength between the interior panel 2 and the exterior panel 1 can be maintained.

Then, as shown in FIG. 2(b), after bending the exterior plate 1 so as to cover the edge 2a of the interior plate 2, spot welding vi6 is performed between the exterior plate 1 and the interior plate 2. It is heated to harden the thermosetting resin layer 4 to form the hemming portion (see FIG. 1).
