DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting an air spoiler, which is a blow-molded hollow cylinder, to a vehicle body.

[0002]

2. Description of the Related Art Generally, an air spoiler is a half-shell air spoiler obtained by press-molding a plate-shaped resin material (SMC prepreg), or a hollow air spoiler obtained by blow-molding a cylindrical resin material (parison). Air spoiler. These air spoilers are attached to the upper edge of the rear part of the vehicle body and the like, and the wing portion receives an airflow that flows on the roof and reaches the rear part with little turbulence, thereby preventing the vehicle body from rising during high-speed traveling. Therefore, a strong air resistance acts on the air spoiler, and therefore, a sufficient strength is particularly required for a structure for attaching the air spoiler to the vehicle body.

For example, Japanese Patent Laying-Open No. 5-238321 discloses a structure for attaching a half-shell air spoiler to a vehicle body. According to the mounting structure disclosed in the publication,
The air spoiler has a mounting surface to the vehicle body formed along the rear edge, and a bolt is integrated with the mounting surface. On the other hand, a bolt insertion hole is formed in a mounting portion of the vehicle body panel, and the bolt is inserted into the insertion hole and fastened by a nut from the back side of the vehicle body panel to attach the air spoiler to the vehicle body.

[0004]

However, the mounting structure disclosed in the above publication is suitable for a spoiler having a semi-shell shape to the extent that it is tired. Although it is possible to integrate the bolts, when this mounting structure is applied to an air spoiler of a hollow body formed by blow molding, the buried portion of the bolt becomes fragile, and sufficient mounting strength cannot be obtained.
Because, in blow molding, a simple cylindrical molten resin (parison) is expanded into a complicated three-dimensional shape, so that the complicated parts such as the corners and protrusions that become the mounting parts are compared with flat parts. This is because the bolt and the like cannot be integrally formed with sufficient strength.

Accordingly, the present invention solves the above-mentioned problems, and obtains a mounting structure which can be mounted on a vehicle body with sufficient mounting strength even if the air spoiler is made of a synthetic resin hollow body formed by blow molding and has an uneven thickness. The purpose is to:

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention relates to a structure for mounting a synthetic resin air spoiler made of a blow molded hollow body to a vehicle body, wherein the air spoiler has a simple surface mounting structure. A fastener engaging means is integrated with the surface, and one end of an interposition body having an extending portion extending near the edge is fixed to the mounting surface by a fastener engaging with the fastener engaging means. The main structure is a blow-molded hollow air spoiler mounting structure, characterized in that the extended portion of the intervening body is fixed to the mounted portion of the vehicle body with an appropriate mounting member.

[0007] Preferably, the mounting surface of the air spoiler is substantially the same as the mounting portion of the vehicle body as a whole,
A recess is formed at the center of the mounting surface, and the fastener engaging means is formed and integrated with the bottom surface of the recess.

[0008] More preferably, the bottom surface includes a first bottom surface in which the fastener engaging means is integrated, and a second bottom surface recessed so as to accommodate the mounting member of the intervening body.

According to the mounting structure of the present invention, since the mounting surface is formed avoiding a flat surface, that is, a portion which is extremely thin by blow molding, it is possible to embed the fixing member firmly and integrally form the fixing device. it can. In addition, the air spoiler is fixed to the mounting portion of the vehicle body via an interposition between the mounting surface of the air spoiler and the vehicle body so that the air spoiler and the vehicle body are not directly fixed, regardless of the position of the mounting surface. Since the part to be mounted can freely select an optimal part in terms of strength, workability, appearance, etc., air with good workability, sufficient mounting strength is secured, and there is no problem in appearance. A spoiler mounting structure can be obtained.

In the case where the concave portion is formed in the mounting surface, the intervening body and the mounting member can be completely accommodated in the concave portion, so that the mounting surface can be completely adhered to the mounted portion of the vehicle body. The appearance can be further improved.
