Abstract

PURPOSE:To prevent a bumper molding from being thermally deformed at the corner section by configurating a device in such a way that a convex section is formed along the longer direction of the bumper main body at the center section of a long groove around the corner of the bumper main body, and the bumper molding is fitted into the bumper while a portion of the bumper molding comes in contact with the convex. CONSTITUTION:A long groove 4 is formed at a center section of a bumper main body 2 in the longer direction, and a bumper molding 3 is fitted into the said long groove 4. In this configuration, a convex 8 which has the specified height from the bottom, is formed along the longer direction at the center section of the long groove 4 around the corner 2a of the bumper main body 2. And the bumper molding 3 is fitted into the bumper while a portion of the bumper molding comes in contact with the said convex 8. The configuration is capable of preventing the outer surface of the bumper molding 3 from forming concaves in an irregular shape due to thermal deformation, because the convex 8 holds the bumper molding 3 from the inside even if the bumper molding 3 is deformed while it is bent along the corner 2a.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mounting structure for a decorative molding to be mounted on a bumper of an automobile.

BACKGROUND OF THE INVENTION Generally, in automobile bumpers, which are mainly made of synthetic resin, a decorative molding extending along the longitudinal direction of the bumper is attached at a substantially central position to enhance the appearance. That is, a bumper molding 3 is fitted and fixed to the bumper body 2 attached to the front of the automobile I shown in FIG.
As shown in the cross-sectional view of FIG. 4, a bumper molding 3 having a cavity is fixed to a clip 5 in a long groove 4 formed approximately in the longitudinal center of the bumper body 2.

Problems to be Solved by the Invention However, in such a conventional bumper molding mounting structure, the bumper molding located at the corner of the bumper body is deformed by an unreasonable external force, and the bumper molding is mounted at the corner. There was a problem in that this pambamole was deformed by heat and its appearance deteriorated. That is, the bumper molding 3 located along the line ■-■ in FIG.
The shape shown in Figure (A) is thermally deformed to the shape shown in Figure (B), and a recessed portion 6 is generated on the front surface of the Pambamall 3, which causes a deterioration in the appearance.

On the other hand, as a means to solve the above-mentioned problems, a structure in which a filling member 7 shown in FIG. 6 is stuffed inside the pamba mold 3 located at the corner portion is also used. The material of the filling member 7 is not particularly limited, but it must be able to withstand the thermal A-type stress of the bumper mold 3. However, such a packing structure of the filling member 7 has disadvantages such as tedious work during assembly and increases in the weight of the vehicle, and can be said to have low practical value.

Therefore, the present invention eliminates the problems of the conventional bumper molding mounting structure as described above, eliminates thermal deformation of the bumper molding at the corner, and provides a mounting structure that is easy to assemble and does not increase weight. This is what we provide.

Means for Solving the Problem A convex portion having a predetermined length along the longitudinal direction of the bumper body is provided at approximately the center of the long groove corresponding to the corner portion of the bumper body, and one end of the bumper molding is brought into contact with the convex member. They are brought into contact and fixed by fitting.

Since one end/portion of the bumper molding that is fitted and fixed in the long groove of the working bumper body is in contact with the convex portion of the corner portion,
Even if an external force is applied to the extrusion-molded pamba molding along the corner shape of the bumper body to deform it and attach it, since the convex portion supports the bumper molding from the inside of the bumper molding, heat will be applied to the pamba molding and the surface of the pamba molding will not dent. This eliminates the occurrence of thermal deformation such as

EXAMPLES Below, a mounting structure for a pamba mall according to the present invention will be explained based on the drawings. That is, a long groove 4 is formed at approximately the center position in the longitudinal direction of the bumper body 2 shown in FIG. It is provided along the longitudinal direction of the bumper main body 1. Therefore, the bumper molding 3 fitted and fixed in the long groove 4 is inserted into the bumper body 2 inward of the bumper molding 3 having a cavity, as shown in FIG.
It has a structure in which a surface marking convex portion 8 protruding from the surface contacts.

Therefore, even if this bumper molding 3 is bent and deformed along the shape of the corner part, since the convex part 8 supports the bumper molding 3 from the inside, dents will not occur on the surface of the bumper molding due to irregular thermal deformation. This is to prevent

The mounting structure of the bumper mold according to the present invention described in detail includes providing a convex portion of a predetermined length along the longitudinal direction of the bumper main body at the center position of the long groove corresponding to the corner portion of the bumper main body, and attaching the bumper mold to one end of the bumper mold. Since the part is fitted and fixed in contact with the protrusion, even if the bumper molding is bent and deformed along the shape of the bumper body, the protrusion firmly supports the bumper molding from the inside of the bumper molding. It is possible to prevent the surface from being thermally deformed.

Furthermore, since the convex portion does not pose any hindrance to the bumper molding installation work, the assembly work is simplified and a bumper molding mounting structure can be obtained that does not increase weight.
