Problems solved by technology

[0003] The existing steel front bumper has high material density and heavy weight, which makes the weight of the car itself too high to a certain extent. At the same time, the bumper and the connecting parts are mainly connected by bolts and nuts, but it is easy to use the nuts for a long time. Loose, which will cause the bumper to fall, which is very dangerous

Abstract

The invention belongs to the field of crashproof bars, and particularly relates to a basalt fiber composite front crashproof bar which comprises a main body, the interior of the main body is of a hollow structure, cross beams are welded to the two sides of the main body, end covers are arranged at the two ends of the main body, and the two cross beams are provided with the same connecting piece. Bolts are inserted between the cross beams and the connecting pieces, nuts are installed on the bolts, horizontal grooves are formed in the sides, close to each other, of the two cross beams, guide columns are fixedly installed on the inner walls of the horizontal grooves, sliding sleeves are connected to the guide columns in a sleeving mode, telescopic grooves are formed in the top sides of the sliding sleeves, and U-shaped frames are installed in the telescopic grooves in a sliding mode. The defects in the prior art are overcome, the nut on the bolt can be more stable, the deviation phenomenon is avoided, and then connection of the bumper is more stable.

Description

technical field [0001] The invention relates to the technical field of anti-collision bars, in particular to a basalt fiber composite front anti-collision bar. Background technique [0002] The bumper is stamped from cold-rolled steel plate and connected with the frame. As the first barrier of passive safety of the car, the bumper is an important safety device that absorbs and mitigates the external impact force and protects the front and rear parts of the body. [0003] The existing steel front bumper has high material density and heavy weight, which makes the weight of the car too high to a certain extent. At the same time, the bumper and the connecting piece are mainly connected by bolts and nuts, but it is easy to use nuts for a long time. It is very dangerous if it is loose, which will cause the bumper to fall off. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and propose a basalt fiber ...
