Vehicle anti-collision beam and manufacturing method thereof

Abstract

The invention provides a vehicle anti-collision beam and a manufacturing method thereof, and particularly provides a high-strength anti-collision beam with multi-section buffering and the manufacturing method thereof. The vehicle anti-collision beam comprises a plastic bumper shell, an energy absorbing buffer layer, a reinforcing cross beam, energy absorbing boxes and bolts, and the plastic bumpershell, the energy absorbing buffer layer and the reinforcing cross beam are sequentially connected from outside to inside; and the energy absorbing boxes are separately arranged at the two ends on one inward side surface of the reinforcing cross beam, and the energy absorbing boxes are connected with the reinforcing cross beam and a vehicle body main body. The manufacturing method of the vehicleanti-collision beam comprises the steps that (1) the plastic bumper shell is prepared from a compression molding process; (2) the reinforcing cross beam is prepared by adopting a high-strength steel hot stamping method; (3) the energy absorbing buffer layer with the same size as the reinforcing cross beam is prepared by adopting carbon fiber composite rubber materials, and the plastic bumper shell, the energy absorbing buffer layer and the reinforcing cross beam are connected through the bolts; and (4) the two energy absorbing boxes are connected to the two ends of the inner side of the reinforcing cross beam, and the reinforcing cross beam is connected to an installation plate through the energy absorbing boxes.

Description

technical field [0001] The invention relates to the technical field of auto parts and manufacturing methods thereof, in particular to an anti-collision beam for vehicles and a manufacturing method thereof. Background technique [0002] The anti-collision beam is a device used to reduce the absorption of collision energy when the vehicle is hit by a collision. It is composed of a main beam, an energy-absorbing box, and a mounting plate connected to the car. The main beam and the energy-absorbing box can effectively absorb when the vehicle collides at a low speed. The collision energy minimizes the damage of the impact force to the longitudinal beams of the body, and thus exerts its protective effect on the vehicle. Chinese patent CN102923080B is an automobile front anti-collision beam assembly, which is characterized in that: the two ends of the anti-collision beam assembly are connected to the energy-absorbing box through the connecting plate respectively, and the energy-abs...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the problem that the anti-collision beam protection method in the prior art is single and the impact force on the vehicle body is too large, the present invention provides a vehicle anti-collision beam and a manufacturing method thereof, a vehicle anti-collision beam, It is characterized in that it includes a plastic bumper shell, an energy-absorbing buffer layer, a reinforcing beam, an energy-absorbing box and bolts; the plastic bumper shell, the energy-absorbing buffer layer, and the reinforcing beam are sequentially connected from the outside to the inside, and the reinforcing beam is inward. An energy-absorbing box is provided at both ends of one side, and the energy-absorbing box is connected to the reinforcing beam and the main body of the vehicle body
