Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper structure in which a sheet metal bumper is mounted on an upper edge of a resin bumper. 2. Description of the Related Art A bumper to be mounted on an automobile body has been provided in which a resin balance bumper is mounted below a sheet metal bumper including a plated corner portion. As shown in FIG. 3, the structure of the sheet metal bumper is such that two members, a center portion 10 and a corner portion 11, are connected by bolts 13 via brackets 12, and a resin balance bumper 14 is also shown in FIG. As described above, the structure is such that the screw 15 and the grommet screw 16 are fastened and fixed to the lower side of the center portion 10. [0005] As shown in FIG.
A bracket 17 is fixed to a part of the bumper arm 1 by welding or the like, and the bumper arm 1 is attached to the bracket 17 on a vehicle body.
8 is fixed with bolts, and the balance bumper 14 is connected to a bumper arm 18 via a bumper support 19. [0005] In the above conventional structure, the sheet metal bumper is basically mounted and fixed to the vehicle body, and the structure is such that the resin balance bumper 14 is mounted on the sheet metal bumper. Therefore, in the case where the easily damaged corner portion is damaged and is replaced, it is necessary to remove the sheet metal bumper from the vehicle body and attach and fix a new sheet metal bumper to the vehicle body. Further, the sheet metal bumper requires a large number of components in a structure for connecting the center portion 10 and the corner portion 11, and there is a problem that the cost is increased due to a complicated structure. SUMMARY OF THE INVENTION An object of the present invention is to improve appearance and repairability by attaching a sheet metal bumper to an upper edge portion of a resin bumper as a main component, and to reduce costs. [0008] In order to achieve the above object, the gist of the present invention is to provide an L-shaped concave portion having a vertical surface and a horizontal surface at an upper edge of a resin bumper, and a vertical bent flange which is in contact with the vertical surface. and mechanical fastening in any of abutment of at least the vertical bending flange and a horizontal folded flanges sheet metal bumper having a horizontal break flanges Taise' placed on the horizontal surface in the recess of the resin bumper, the sheet metal bumper
Is surrounded by a balance bumper made of a resin bumper . An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a resin bumper, and 2 is a sheet metal bumper attached to the resin bumper 1. As shown in FIG. 2, the resin bumper 1 is provided at its upper edge with an L-shaped concave portion having a vertical surface 1a and a horizontal surface 1b. The sheet metal bumper 2 has a center portion and a corner portion formed integrally with each other, and has a vertically bent flange 2a which is in contact with a vertical surface 1a of the resin bumper 1 and a horizontal flange which is in contact with and mounted on the horizontal surface 1b. And a bent flange 2b. The vertically bent flange 2 of the sheet metal bumper 2
the a is welded nut 3, for example, bending the horizontal
The flange 2b is placed in contact with the horizontal surface 1b of the resin bumper 1
Then, the vertical bent flange 2a is brought into contact with the vertical surface 1a of the resin bumper 1, a bolt 4 is screwed into the nut 3, and the sheet metal bumper 2 is fastened and fixed to a concave portion of the upper edge of the resin bumper 1. is there. In FIG. 2, reference numeral 6 denotes a bumper arm, which is fixed to a vertical surface 1a and a horizontal surface 1b of the resin bumper 1 by a bolt (not shown). Since the present invention has a structure as described above, the sheet metal bumper 2 is assembled to the recess at the upper edge of the resin bumper 1 by a simple coupling structure using bolts 4, and the resin bumper 1 is arranged around the sheet metal bumper 2. Embodies the design enclosed by the balance panel. The upper portion 1c of the resin bumper 1 in which the sheet metal bumper 2 is incorporated is supported by the upper retainer 5, and is fixed to the vehicle body via the bumper arm 6. As described above, the bumper according to the present invention basically has the resin bumper 1 attached and fixed to the vehicle body via the bumper arm 6. The sheet metal bumper 2 incorporated in the resin bumper 1 has a concave portion of the resin bumper 1. Can be easily detached. Therefore, in the case where the corner portion of the sheet metal bumper 2 which is easily damaged is replaced due to damage, the detachable replacement operation of the sheet metal bumper 2 can be performed with the resin bumper 1 attached to the vehicle body. Repair becomes possible by replacing only 2. In the above embodiment, the vertical bent flange 2a of the sheet metal bumper 2 and the vertical surface 1a of the resin bumper 1 are fastened and fixed by the bolts 4.
Horizontal bent flange 2b and horizontal surface 1b of resin bumper 1
May be fixed by bolting, or both. Further, in the above embodiment, the mechanical fastening means is exemplified by bolting, but a clip or the like is also possible. As described above, according to the present invention, the structure of the sheet metal bumper does not require a plurality of parts and its connecting parts as in the prior art, and furthermore, the resin which is basically mounted and fixed to the vehicle body. Since the sheet metal bumper can be assembled to the bumper with a simple connection structure, the workability of assembling and the repairability of the sheet metal bumper are improved, and the accuracy and cost are reduced by reducing the number of parts. Has a merit that a design bumper in which the design is surrounded by a balance panel made of a resin bumper can be provided.
