Car front safety anti-collision beam

Abstract

The invention discloses a car front safety anti-collision beam. The car front safety anti-collision beam comprises a body, a truss and an energy suction box fixedly connected with the truss, the trusscomprises a first trapezoidal body, a second trapezoidal body and a third trapezoidal body which are connected in sequence, the transverse dimension of the second trapezoidal body is gradually decreased from the inner side of the body to the outside, and the transverse dimension of the first trapezoidal body and the transverse dimension of the third trapezoidal body are gradually increased from the inner side of the body to the outside; and the first trapezoidal body, the second trapezoidal body and the third trapezoidal body are all connected with the body. The truss disperses local impact force into the three trapezoidal bodies in the mode that one of the first trapezoidal body, the second trapezoidal body and the third trapezoidal body extrudes the other two to generate displacement, and the impact force is transmitted to the whole body through the three trapezoidal bodies so as to avoid stress concentration. Meanwhile, according to the truss structure, the rigidity of the body canbe improved, and the anti-collision performance of the body is improved.

Description

technical field [0001] The invention relates to an automobile front safety anti-collision beam. Background technique [0002] With the continuous development of the domestic economy, the number of families owning cars is also increasing, accompanied by the continuous improvement of the requirements for car safety performance, which makes the research on the field of car safety technology more and more important. The function of the anti-collision beam is to absorb the energy generated by the collision of the car when the car collides, so as to avoid or reduce the damage to people. Specifically, when a car collides, it first acts on the anti-collision beam of the car, and then causes the anti-collision beam to bend and deform, and then is transmitted to the energy-absorbing box of the car by the anti-collision beam. Minimize the harm to people and protect the life and property safety of drivers. Therefore, the stiffness of the anti-collision beam, whether it has good energy...

AI Technical Summary

Problems solved by technology

However, the structure of the existing anti-collision beams of automobiles is too simple, which leads to insufficient rigidity and stress concentration, and when a collision occurs, the front anti-collision beams of automobiles cannot effectively transfer the collision energy to the energy-absorbing box; The structure of the box is simple, the energy absorption effect is poor, and it cannot effectively protect the car occupants
