Automobile anti-collision beam and manufacturing method thereof

Abstract

The invention discloses an automobile anti-collision beam and a preparation method. The anti-corrosion beam comprises a transverse beam and an energy absorption plate, wherein the cross section of the energy absorption plate is of a U-shaped structure; an outwards projected curve surface is formed in the length direction of the energy absorption plate; in addition, an outwards projected arc-shaped structure is arranged on the energy absorption plate in the length direction; the two ends of the energy absorption plate are provided with outwards projected bulges; holes are formed in the top surface of the energy absorption plate; the energy absorption plate and the cross beam are connected to form a sealed cavity; the sealed cavity is filled with buffer materials bonded with the inner wall of the sealed cavity. The automobile anti-collision beam has the advantages that the structure is simple; the manufacturing is convenient; the energy absorption effect is good; the safety performance is high; in addition, the damage of other parts can be reduced, so that the repair cost is reduced. Through the curve surface deign and the arc-shaped structure of the energy absorption plate, the deformation capability of the energy absorption plate is enhanced; the fast transfer of collision force is retarded; the buffer materials between the energy absorption plate and the cross beam can realize high intensity; certain elasticity is realized; the collision force generated in the collision process can be further relieved.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an anti-collision beam and a preparation method thereof. Background technique [0002] With the advancement of science and technology, automobiles have also developed rapidly. In our country, the use of cars is very high, and the number of cars is also increasing year by year. The problems of traffic congestion and safety are becoming more and more prominent, and the traffic accidents that follow frequently occur. Of course, some force majeure traffic accidents cannot be completely avoided. As an important part of a car, the anti-collision beam can maximize the safety of occupants during a vehicle collision. Therefore, it is of great significance to improve the reliability of automobile anti-collision beams. [0003] At present, most of the anti-collision beams on the market have a single structure, including only the anti-collision beam and the rear energy-absorbing ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the anti-collision beams on the market have a relatively simple structure, including only the anti-collision beam and the rear energy-absorbing box, and the two ends of the anti-collision beam are welded together with the rear energy-absorbing box

When different degrees of collisions occur, the energy absorption effect of the anti-collision beam is poor, which is likely to cause life-threatening danger to the driver or occupant in the parking space, and is likely to cause damage to other parts, which increases the maintenance cost
