Description

Top mount of rear bumper for vehicle {A BINDER OF A REAR BUMPER FOR A CAR}

The present invention relates to an upper stand of the rear bumper for an automobile, and in particular, it is possible to prevent damage to the tail car body due to an inner collision of the bumper due to an external impact, and to prevent a deterioration of the appearance of the assembly, as well as a simple bumper. In addition to the assembly operation for the vehicle body is made only by operation, the assembly portion and the fixed portion is formed in a position to facilitate the operation to improve the work efficiency.

In general, the rear end of the car is mounted with a rear bumper to protect the body and occupants from external shocks such as collision of other vehicles, the rear bumper is made of a flexible material such as resin to cushion the external impact A bumper face, an energy observer form filled and fastened inside the bumper face to absorb and alleviate the external shock, and fastened to the vehicle body to fix and support the energy observer form and the bumper face to the vehicle body. It is made of a retainer or the like.

Here, the bumper consisting of the bumper face and the energy observer foam is conventionally fastened to the rear end of the vehicle body as shown in FIGS. 5, 6, and 7, and the conventional rear bumper fixing shown in FIG. In order to support the energy observer foam and to fix the bumper face, a plurality of retainers 71 bent and formed in a substantially inverse " c " cross section are arranged and fastened horizontally to the end surface of the rear panel 11, In the state where the fixing part of the bumper 21 abuts on the front end of the retainer 71, the fastener 72 is inserted into the inner side of the retainer 11, and the junction between the retainer 71 and the bumper 21 is inserted. The upper end of the bumper 21 is fixed to the vehicle rear panel 11 or the like.

In addition, the conventional rear bumper fixing shown in FIG. 6 has a plurality of joint portions of the bumper 21 and the rear panel 11 in a state where the front end of the bumper 21 is abutted on the upper surface of the rear panel 11. It is fixed by a screw 81 which is to be inserted and fastened downward from an upper portion of the top, and a grommet 82 located inside the rear panel 11 so as to fix the screw 81.

In addition, the rear panel bumper shown in FIG. 7 is fixed to the rear panel 11 while the front end of the bumper 21 is extended and bent downward to be brought into contact with the end surface of the rear panel 11. And the expansion part of the bumper 21 is fastened via the bolt 99 and the nut 93, and the bumper 21 is expanded by the nut 93 while being able to improve the adhesion of the expansion part of the bumper 21. A belt-shaped bracket 91 is joined to the inner side of the expansion part to prevent breakage of the part, and thus the upper end of the rear bumper 21 is fastened.

However, as shown in FIG. 5, as the upper end of the bumper 21 and the upper end of the retainer 71 are fixed to the vehicle body such as the rear panel 11 without any supporting force, the bumper 21 may be caused by an external impact applied to the bumper 21. ) Is moved toward the rear panel 11, the retainer 71 made of the upper end and the steel material of the bumper 21 is impacted with a vehicle body such as the rear panel 11, as well as the rear panel 11, ) Is damaged or damaged, and as shown in FIG. 6, the bumper 21 is fixed to the upper end of the rear panel 11 only by the bumper 21 itself. In the case of cracks or severe cracks in the government, the bumper 21 needs to be replaced, as well as fixing members such as screws 81 are exposed to the outside, resulting in a deterioration in appearance. 92) and the bumper 21 is mounted by fixing members such as nuts 93. Since the tightening operation of the bolts 92 is performed inside the rear panel 11, operation of the work tool becomes inconvenient, and it becomes difficult for the operator to observe and observe the work efficiency and, of course, the bumper 21. ), The support of the nut 93 to dismantle and rotate the bolt 92 is required, so that the bumper 21 can be supported and fixed to the nut 93 fastened on the inner surface of the bumper 21. There is a problem that additional work is required, such as the need to separate the energy observer form.

Accordingly, the present invention has been made to solve the above problems, and to securely support the upper fixing portion of the rear bumper, as well as to prevent damage to the bumper and the fixing member to prevent the appearance deterioration, the assembly and The purpose is to provide an upper fixing stand of the rear bumper for automobiles to facilitate the fastening operation.
