Abstract

PROBLEM TO BE SOLVED: To provide a temporary hook means for sticking a resin panel to a metal frame at a low cost by integrally molding the hook means hooking the end edge section of a plate member on a metal member in a body structure connected with the extrusion-molded metal frame member and the synthetic resin plate member with an adhesive. SOLUTION: A rear member 1 corresponding to the installation portion of a rear wheel suspension device at the rear section of a body is molded into a shape connected with a pair of hollow rectangular cross sections having different cross sectional areas. The end edge sections of a rear floor panel 4 made of a synthetic resin material and a rear wheel house 5 are hooked on the end sections in the vehicle width direction of the rear member 1, and hook sections 6 are formed to prevent the floating of them. The hook sections 6 are constituted of shelf-like sections 7 supporting the lower faces of the side end sections of the members 4, 5 and hook lugs 8 hooked on the upper sides of the end edge sections. The rear floor panel 4 and the rear wheel house 5 are stuck in the temporary fixed state between the shelf-like sections 7 and the hook lugs 8.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile body structure constructed by welding hollow members extruded of a light metal material such as aluminum to each other, and particularly to a metal frame member and a synthetic resin body. The present invention relates to a vehicle body structure of an automobile, which is joined to a plate member using an adhesive.

[0002]

2. Description of the Related Art A long hollow material extruded from a light metal material such as aluminum with a constant cross-sectional shape allows the cross-sectional shape to be set relatively freely and has a thickness in the horizontal and vertical directions. Since they can be formed integrally by being made different from each other, a desired strength characteristic according to the site of use can be obtained with high efficiency, and therefore, their use as a frame constituent material for automobiles has recently been drawing attention.

On the other hand, in the case of a space frame having a welded structure of an extruded material, a member that does not substantially contribute as a strength member, such as a partition wall of a wheel house or a floor plate of a trunk room, is positively made into a synthetic resin to be lightweight. It is desirable to promote

[0004]

However, epoxy- or urethane-based reaction-curable resin adhesives are generally used for joining synthetic resin members to metal members, but these have a relatively long curing time. Therefore, provisional fixing measures are required to prevent the joint portion between the synthetic resin member and the metal member from shifting. As a temporary fixing measure, a temporary fixing clip may be provided in a key place or a special jig may be used for clamping, but both of them increase man-hours and affect manufacturing cost. I cannot avoid it.

The present invention has been devised for the purpose of solving the problem imposed on the prior art, that is, the point that special temporary fixing measures are required when bonding a synthetic resin member and a metal member. It was done.

[0006]

In order to achieve such an object, in the present invention, an adhesive is used for a metal frame member formed by extrusion molding and a synthetic resin plate member. In the vehicle body structure of the automobile, the locking means for hooking and stopping the edge of the plate member made of synthetic resin is integrally formed with the metal frame member. In particular, the locking means is composed of a shelf-like portion that supports the lower surface of the edge portion of the synthetic resin plate member, and a locking protrusion that is also caught on the upper side of the edge portion. It is advisable to provide a slope.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows a main part of a vehicle body frame of an automobile to which the present invention is applied. This vehicle body frame is constructed by welding tubular hollow members extruded from a light metal material such as aluminum to each other.

As shown in FIG. 2, the rear member 1 corresponding to the portion where the rear wheel suspension device is provided at the rear part of the vehicle body is integrally formed in a shape in which a pair of hollow rectangular cross-sections having different cross-sectional areas are connected to each other. With the axis of the section extending in the front-rear direction of the vehicle body, it is provided at a position adjacent to the inside of the rear wheel (not shown). The rear member 1 is provided with a seat 2 of a coil spring which constitutes a part of a rear wheel suspension device on its side portion, and a lower end of a rear pillar 3 is connected to its rear end.

At the respective end portions of the rear member 1 in the vehicle width direction, the end portions of the rear floor panel 4 and the rear wheel house 5 made of a synthetic resin material are locked so as to prevent them from rising. A stop 6 is formed. The locking portion 6 is provided on the rear floor panel 4 and the rear wheel house 5.
It is composed of a shelf-like portion 7 that supports the lower surface of the side end portion of the rear end portion, and a locking projection 8 that is also hooked to the upper side of the end edge portion. Since the upper portion of the locking projection 8 is a sloped surface 9, the rear floor panel 4 and When the rear wheel house 5 is pushed in from above, the side edges of the rear floor panel 4 and the rear wheel house 5 are bent by the elastic force of the material itself, and are restored when they get over the apex of the locking projections 8 to form the shelf-like parts 7. The position is held in a form in which the side end is sandwiched between the locking projection 8 and the locking projection 8.

Thus, the rear floor panel 4 and the rear wheel house 5 are temporarily fixed between the shelf-like portion 7 and the locking projection 8 by applying the adhesive in advance on the upper surface of the shelf-like portion 7. Since the state is brought into a state, it is possible to prevent them from being displaced before the adhesive is cured.

[0012]

As described above, according to the present invention, the temporary fixing means for the resin panel can be formed at the time of molding the frame material. Therefore, when the resin panel is bonded to the metal frame without any pressure on the manufacturing cost. Provisional temporary measures can be taken.
