Fixing device for front and rear bumpers of automobile

Abstract

The invention discloses a fixing device for front and rear bumpers of an automobile. The fixing device comprises a fixing groove, a side plate, a heat dissipation groove, an air collection groove, a safety shell, a first clamping groove, a fixing hole, a protective shell, a fixing rod, a limiting plate, a fixing block, a sliding way, a buffer plate, a fixing cross beam, a fixing bolt, a second clamping groove and a limiting groove. The fixing device for front and rear bumpers of an automobile has the advantages that the safety shell, the buffer plate and the fixing cross beam are connected through the fixing rod, the buffer plate is clamped in a limiting groove in the fixing cross beam and the fixing cross beam is slidably connected to the side plate through the limiting plate, so that thefixing bolt can penetrate into the fixing rod accurate and installation of bumpers is facilitated; and meanwhile, the air collecting groove is formed in the side face of the side plate, and the heatdissipation groove is formed in the air collection groove, so that the balance of the temperature in a bumper can be guaranteed, the deformation of the buffer plate can be effectively prevented, and the safety of an automobile is enhanced.

Description

technical field [0001] The invention relates to a fixing device for bumpers, in particular to a fixing device for front and rear bumpers of automobiles, and belongs to the technical field of automobile equipment applications. Background technique [0002] The front and rear ends of the car are equipped with bumpers, which not only have decorative functions, but more importantly, are safety devices that absorb and ease external impact, protect the body and protect the occupants. Among them, the outer plate and buffer material are made of plastic, and the beam is stamped with a cold-rolled sheet with a thickness of about 1.5 mm to form a U-shaped groove; the outer plate and buffer material are attached to the beam, and the beam is connected with the longitudinal beam of the frame by screws. disassembled. The plastic used in this plastic bumper is generally made of polyester and polypropylene, and is made by injection molding. [0003] The current automobile bumper is general...

AI Technical Summary

Problems solved by technology

[0003] The current automobile bumpers are generally fixed with bolts, but the shape of the automobile is irregular, and the fixing bolts are not easy to be screwed into the fixing holes accurately, which brings inconvenience to the fixing work, and the heat dissipation performance of the current automobile bumpers is relatively poor. , and the buffer plate in the bumper is a plastic product, if the heat cannot be removed in time, the buffer plate will be heated and deformed, which will affect the stability of the overall structure of the bumper and bring safety hazards
