Abstract

PROBLEM TO BE SOLVED: To prevent deformation and strain by a method in which more than one caulking shaft is fitted in each fitting part, the corresponding number of fitting holes are formed, the diameter of the hole is set up to be larger than that of the caulking shaft, the shafts are fused to each other between the holes to fix both. SOLUTION: A fitting hole 5 of a film is inserted into a caulking shaft 8. The diameter D of the shaft is made greater than the diameter d6 of the hole 5. The shaft 8 is caulked by a caulking jig 9. The tip part of the jig 9 has a caulking fusion part 10 in the middle and a ring-shaped bank 11 on the periphery of the fusion part 10. The relation between caulking volume x12 and caulking shaft volume y13 is made X>=Y. Since a molten resin in a caulking shaft part does not enter the clearance between a hole formed in a film and the shaft by the relation, fixing can be done in a movable state. The distance between the caulking shafts z14 is changed by the caulking volume x12, and if it is little, the distance z14 needs to be adjusted.

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 their linear expansion coefficients is large, the joint member will be As heating and cooling are repeated, deformation and distortion occur. Alternatively, as disclosed in Japanese Utility Model Publication No. 3-53866, there is also a method in which the mounting portion of the mounting member has a substantially I-shape and a rib of a 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 linear expansion coefficient between the joint members during expansion and contraction, but since it is I-shaped, there is a limitation in the directionality, and the deformation and strain Insufficient to prevent.

のである。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 that both mounting portions are loose, but in such a case, the sheet-shaped mounting member is easily peeled off, which is not an effective means. Therefore, the present invention provides a joint structure with a resin molded product that can prevent expansion and contraction of the sheet-shaped mounting member due to ambient temperature changes to prevent its deformation and distortion, and at the same time have a large bonding strength and are resistant to peeling. It is intended to be provided.

The inventors have found that the above-mentioned problems can be solved by providing them and caulking a caulking shaft at the portion between these holes to fuse them, and arrived at the present invention. That is, according to the present invention, a resin molded product having a caulking shaft projecting and a sheet-shaped mounting member having a mounting hole at a position corresponding to the caulking shaft are mounted by inserting the mounting hole into the caulking shaft and caulking the caulking shaft. A joint structure, wherein each of the mounting portions comprises a plurality of the caulking shafts, and the plurality of mounting holes correspond to each other,
Also, the present invention relates to a joint structure characterized in that a hole diameter is set larger than a caulking shaft diameter, and the caulking shafts are fused to each other at a portion between the mounting holes to fix the both.

いは金属の薄体などがある。In the joining structure of the present invention, the sheet-like mounting member is fixed to the resin molded product by fusion bonding of the plurality of caulking shafts at the portions sandwiched by the mounting holes, that is, the portions between the mounting holes. , It is important that most of the other parts around the mounting holes are free. It should be noted that the number of caulking shafts may be two or three, and in some cases more. Due to the difference in the linear expansion coefficient between the sheet-shaped mounting member and the resin molded product due to such a joint structure, even if the sheet-shaped member contracts or expands due to temperature change, the stress caused by it is different from that of the resin molded product around the mounting hole. It can be relaxed by the free part that is not fixed. 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, when a thin resin film such as an antenna pattern printed film is used, 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 vehicle body (metal) changes, which adversely affects the reception characteristics. However, according to the joining structure of the present invention, even when such a thin film is attached,
It is possible to prevent the film from being warped or deformed. Moreover, in the joint structure of the present invention, the fixing portion of the resin molded product and the sheet-like mounting member is firmly and surely mounted because the caulking shafts are fused and integrated with each other in the portion between the mounting holes. There is no need to worry about peeling. The material of the resin molded product in the present invention is not particularly limited, and a thermoplastic resin or a thermosetting resin can be used. Further, the material of the sheet-shaped mounting member to be mounted on the resin molded product is not particularly limited, and may be general synthetic resin or a thin metal body.

うにすることが好ましい。The inter-caulking distance Z (14) depends on the volume of the caulking volume X (12). When the caulking volume X (12) is small, if the distance Z (14) is too large, the caulking fused portion (10) Since it is difficult to form, it is necessary to adjust Z appropriately. FIG. 5 shows another embodiment, in which a mounting film is attached to a resin molded product by caulking a shaft pedestal (1) having a diameter (b).
6) It is a cross-sectional explanatory view in the case where a distance “a” is secured to the upper mounted product. At this time, the film mounting hole diameter d is d>
In the case of b, the caulking shaft pedestal (16) constitutes a film support portion (15) between the caulking pedestals, as shown in FIG.
In plan view, it is preferable that the film has a dumbbell shape so that the film does not fall down.

Therefore, it is possible to prevent the sheet-shaped mounting member and the resin molded product from being deformed such as warped. Moreover, at the same time, in the joint structure of the present invention, the attachment portion and the attachment portion are integrated by the plurality of caulking shafts at the attachment portion, so that the attachment strength can be improved. By using a plurality of thin crimping shafts, sink marks on the surface of the resin molded product can be prevented.
