Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an assembling method and an assembling operation for assembling exterior parts to an outer panel of an automobile body, such as for assembling an upper helium boiler for a trunk lid. This relates to an assembly collar that is sometimes used.

(Prior Art) Conventionally, when attaching a rear spoiler as an exterior part of an automobile, for example, to the upper surface of a trunk lid as an outer panel of the vehicle body,
A stud bolt is provided protruding from the mounting surface of the rear spoiler, the stud bolt is inserted into a mounting hole drilled in the trunk lid, and a nut is screwed into the inserted stud bolt from the lower surface side of the trunk lid. The most common method is to assemble the An example of such an assembly structure is a mounting structure for a Yasu boiler as shown in Japanese Utility Model Application No. 60-117279. Furthermore, what is shown in the publication is:
A groove is provided on the mounting surface around the stud bolt of the rear spoiler, and the wave groove is filled with a sealer to prevent rainwater, etc. that flows down the gap between the rear spoiler and the trunk lid from penetrating into the bolt threaded area. It is made to be.

(Problem to be Solved by the Invention) However, in the conventional assembly structure as described above, it is difficult to insert the bolt into the mounting hole without accurately aligning the bolt and the mounting hole. If this happens, the tip of the bolt may come into contact with the top surface of the trunk lid, causing the paint on the top surface to peel off and rusting to occur on the trunk lid.
Further, when inserting the bolt, the threaded portion of the bolt hits the periphery of the mounting hole, damaging the thread of the bolt, which not only reduces the strength of the assembly of the rear spoiler, but also makes it impossible to screw the nut into the bolt. In addition, in the above-mentioned publication, a sealer is required separately from the rear spoiler and stud bolts, and the installation work of the sealer is complicated, so it is said that the workability of assembling the rear spoiler is inferior. It had a problem.

In consideration of these points, the present invention provides an assembly method that prevents damage to the vehicle body outer panel and bolts themselves when assembling exterior parts such as the rear spoiler, and in the assembled state, the bolt threaded portion The purpose is to realize a structure that is waterproof to the surrounding area at a low cost.

(Means for Solving the Problems) In view of the above points, the present invention achieves its objects by the method and members shown below.

That is, in the invention according to claim (1), as an assembling method for assembling an exterior part to an outer panel of an automobile body, a collar portion through which the bolt is inserted into a bolt protruding from the exterior part; After inserting a collar integrally formed with a holder part that covers at least the tip of the bolt and inserting the collar into a mounting hole drilled in the outer panel of the vehicle body, the tip of the holder part of the collar is partially inserted. The bolt is exposed from the collar, and a nut is screwed onto the bolt from the back side of the outer panel of the vehicle body to fasten the exterior parts.

In addition, in the invention described in claim (2), when assembling the exterior part to the outer panel of the vehicle body, as an assembly collar that is inserted into at least the tip of a bolt protruding from the exterior part, The assembly of the above exterior parts consists of a collar part interposed in a sealed state between the vehicle body outer plate and the exterior part, a collar part integrally protruding from the collar part, which is engaged with the tip of a bolt. , and a cylindrical holder part whose tip can be partially broken by pressing the bolt.

In the case of JL, after inserting a collar that covers at least the tip of the bolt into a mounting hole in the outer panel of the vehicle body, a part of the tip of the collar is damaged to expose the bolt from the collar, so the bolt cannot be inserted into the mounting hole. The collar prevents the bolt from coming into direct contact with the outer skin of the vehicle before it is inserted into the vehicle body. Moreover, when the bolt is inserted into the mounting hole, the collar prevents the bolt from coming into contact with the periphery of the mounting hole.

In addition, in the invention according to claim (2), the assembly of the exterior parts includes a collar part of the collar interposed between the vehicle body outer plate and the exterior part and a lower end of the collar part. By providing a holder part that protrudes from the bolt and part of its tip is damaged when the bolt is exposed, the collar part prevents water from entering the bolt threading area and the core material of the exterior parts. This prevents damage to the outer panel of the vehicle body due to contact with the vehicle body.

Next, the procedure for attaching the rear spoiler 2 to the upper surface of the trunk lid 1 using the collar 4 will be explained.

When attaching the rear spoiler 2 to the upper surface of the trunk lid 1, as shown in FIG. 1(a), a collar 4 is fitted to the tip of the weld bolt 3, and aligned with the mounting hole 1a of the trunk lid 1. At this time, the tip of the holder part 6 is a conical guide part 6b, and each holder piece 6f is connected by a connecting part 6e, so the weld bolt 3 is not exposed from the holder part 6. do not have. Then, with the above positioning performed, the collar portion 5 is inserted to a position where it comes into contact with the upper surface of the trunk lid 1, as shown in FIG. 1(b). In this case, the weld bolt 3 is quickly inserted into the mounting hole 1a by the guide part 6b of the collar 4, and since the tip and surrounding threads of the weld bolt 3 are covered by the holder part 6, There is no contact with the trunk lid 1. Thereafter, by strongly pushing the rear spoiler 2 toward the trunk lid 1, the bolts 3 forcefully press the guide portion 6b, and as shown in FIG. 1(C), the connecting portion 6e is broken and this When the connecting portion 6e breaks, each holder piece 6f is pushed by the bolt 3 and its tip expands outward, thereby exposing the weld bolt 3 below the trunk lid 1. Finally, as shown in FIG. 1(d), the seat nut 7 is screwed and fastened from the bottom side of the trunk lid, thereby completing the installation of the rear spoiler 2. At this time, the holder portion 6 is pressed against the lower surface of the trunk lid by the seat surface 7a of the nut 7 and is deformed. As a result of the rear spoiler being assembled in this manner, the periphery of the bolt 3 between the rear spoiler 2 and the trunk lid 1 is sealed by the collar portion 5, preventing rainwater etc. from entering the bolt threaded portion. This prevents rust from occurring, and since the core material 2e does not come into contact with the trunk lid 1, the trunk lid 1 is also prevented from being damaged. In addition, the assembly of the collar 4-beam mill boiler 2 does not need to be removed later, so the assembly is excellent in workability.

In order to enhance the effect of preventing the infiltration of rainwater, etc., as shown in FIG.
It is also possible to fit a rubber gasket 8 around the outer periphery of the holder portion 6 at the lower end. If this configuration is adopted,
When the rear spoiler 2 is assembled, the lip portion 5b
The core material 2b of the rear spoiler 2 is tightened by the tightening force of the nut 7.
