Abstract

PROBLEM TO BE SOLVED: To prevent generation of deformation and strain and increase fixing strength by disposing a floating hole and/or slitting at a sheet-shaped attaching member just near the periphery of an attaching hole corresponding to a staking shaft part. SOLUTION: A sheet-shaped attaching member floating hole 6 is formed annular so as to surround the attaching hole 5 of a sheet-shaped attaching member 3 where a staking shaft 9 is inserted, and the attaching hole 5 of a film is inserted in the staking shaft 9. At this time, a relationship between the thickness (d) of the attaching part on the resin formed product side and the outside diameter dimension C of the floating hole of the film is preferably d>c in appearance. A relationship between a staking shaft diameter 8 and a film attaching hole 7 is preferably b>=a, which is a tight attaching relationship without play, and in this case, a positioning action works. It is thus possible to relieve sufficiently stress due to even the expansion or contraction of the resin formed product or the sheet-shaped attaching member with a temperature change, if any.

Description of the Related Art Conventionally, as a means for attaching another member to a resin molded product, there is a method in which a boss portion provided in the molded product is fitted in a hole of another component, and the boss portion is friction welded and caulked to join. (For example, Jikken 5-18131). However, in this method, since the mounting member is tightly fixed to the molded product at the joint, when the materials of the two are different, if the difference in linear expansion coefficient between them is large, the joint member will be As heating and cooling are repeated, deformation and distortion occur. Further, it has been proposed to provide a radial notch in a hole of a plate when attaching a metal plate to a stud provided on a resin member (Japanese Patent Laid-Open No. 483/1990).
No. 27), in this case as well, after the stud is heat-crimped, the stud and the plate are tightly integrated with each other, and the same problem as described above occurs. Further, as disclosed in Japanese Utility Model Publication No. 3-53866, there is also a method in which the mounting portion of the mounting member is formed into a substantially I-shape and the rib of the molded product is inserted into this and the rib is welded and caulked. In this method, the stress applied to the mounting member is partially relieved due to the difference in the coefficient of linear expansion during expansion and contraction of the joining member, but since it is I-shaped, there is a limitation in the directionality and there is no deformation or strain. Insufficient to prevent.

部材が剥がれやすくなるので有効な手段ではない。As described above, in the conventional joining structure, there is a high possibility that the resin molded product may be deformed or distorted, and in some cases, wrinkled, when a sheet-shaped member is attached. This is a problem in the joining structure for vehicles such as automobiles where there is a large difference between high temperature and low temperature. As a solution to such a problem, it is conceivable to loosen both mounting portions, but in such a case, the sheet-shaped mounting member is easily peeled off, which is not an effective means.

明に至った。Means for Solving the Problems As a result of earnest studies, the inventor of the present invention constructed a caulking shaft in which each mounting portion of a thermoplastic resin molded product is integrated, and a corresponding sheet-shaped mounting member is mounted with a corresponding mounting member. It is possible to solve the above-mentioned problems by providing holes and arranging a seat loosening hole and / or a notch in the immediate vicinity of these holes, attaching this to a caulking shaft, and then caulking the caulking shaft to fuse them. The present invention has been completed and the present invention has been achieved.

After that, in a joint structure of the resin-molded product formed by crimping the head portion of the caulking shaft portion and the sheet-shaped mounting member, a loose hole is formed in the sheet-shaped mounting member near the mounting hole portion corresponding to the caulking shaft portion.

The sheet-shaped mounting member joined by caulking the caulking shaft portion of the resin molded product is provided with a seat loosening hole and / or a notch in the immediate vicinity of the joint portion. By adopting such a joint structure, even if the sheet-shaped member contracts or expands due to temperature change, the stress caused by the difference in linear expansion coefficient between the sheet-shaped mounting member and the resin molded product causes It can be relaxed by the incision site. Therefore, the joining structure of the present invention is suitable for mounting parts for vehicles such as automobiles with drastic temperature changes, for example, a lighting panel in a cluster, a film printed with a receiving antenna pattern for keyless entry, or a thin metal plate. It can also be applied to fixing to a resin molded product such as a nameplate made of, for example. In the conventional bonding structure, in the case of a thin resin film such as an antenna pattern printed film, the attached film may warp due to contraction or expansion due to temperature change due to the difference in heat capacity. The distance between the pattern and the car body (metal) changes, which adversely affects the reception characteristics. However, according to the joint structure of the present invention, even when such a thin film is attached, the film is not warped or deformed. Can be prevented. Moreover, in the joint structure of the present invention, the fixing portion between the resin molded product and the sheet-shaped mounting member is firmly and firmly fixed because the caulking shaft is fused and integrated with the sheet-shaped mounting member at the mounting hole portion. Since it can be attached to, there is no need to worry about peeling.

の形状を選択することができる。As described above, according to the joining structure of the present invention, even if the resin molded product or the sheet-shaped mounting member mounted thereto expands or contracts due to the temperature change, the stress caused thereby can be sufficiently relaxed. Therefore, it is possible to prevent the sheet-shaped mounting member from being deformed, such as warped, in particular, permanently deformed. Further, when the expansion and contraction directions of the sheet-shaped mounting member when mounted on the resin molded product are clear, it is possible to select an appropriate shape of the loose hole and / or cut according to the directionality.
