Description

Technical Field

[0001] The utility model relates to the technical field of metal bumpers, in particular to a stable metal bumper that is convenient for installation. Background Art

[0002] An automobile bumper is a safety device that absorbs and mitigates external impact forces and protects the front and rear parts of the vehicle body. The bumper is composed of three parts: an outer panel, a buffer material, and a cross beam. The outer panel and the buffer material are mostly made of plastic, which is more aesthetically pleasing, and the cross beam is made of metal and undertakes the protection function.

[0003] With the development of technology, combined cross beams have gradually been applied. By connecting and fixing multiple cross beams through strengthening beams, the production cost can be reduced while ensuring the protection effect. However, for some existing bumpers, the strengthening beams and cross beams need to be sequentially fixed inside the exterior trim panel composed of the outer panel and the buffer material. Since the automobile exterior trim panel is not a flat structure, it is difficult to accurately position the strengthening beams and cross beams during installation, resulting in troublesome installation of the bumper. Therefore, in view of the above problems, a stable metal bumper that is convenient for installation is proposed. Summary of the Utility Model
