The invention discloses an anti-collision beam for a vehicle. The anti-collision beam comprises an anti-collision beam main body and an energy absorption box, the abutting face is provided with a connecting area used for arranging an energy absorption box. A collision face opposite to the abutting face is further formed on the anti-collision beam body, and the direction from the collision face to the abutting face is the stress direction of the anti-collision beam body. Weak force areas are symmetrically arranged on the collision surface, and the cross sections of the weak force areas are the same as those of the end parts of the anti-collision beam main body; the weak force area is composed of at least one pair of welding seams arranged at intervals, and the distance between the weak force area and the central axis of the anti-collision beam body is d1. A deformation area of the anti-collision beam body is arranged between the weak force areas, the deformation area deforms in the stress direction of the anti-collision beam body, and the invasion amount with the distance being d2 is formed. The anti-collision beam has the advantages that the three welding seams are arranged on the anti-collision beam body to guide the anti-collision beam body to deform, the deformation quantity of the anti-collision beam body is minimum, then force transmitted to a vehicle body after the anti-collision beam is collided is reduced, and damage to vehicle sound and threat to personal safety of a driver and passengers are effectively reduced.
本发明揭示了一种车用防撞梁,包括防撞梁主体和吸能盒;抵接面上设置有用于设置吸能盒的连接区;防撞梁主体上还形成有与抵接面相对的碰撞面,自碰撞面向抵接面的方向为防撞梁主体的受力朝向;碰撞面上对称设置有弱力区,弱力区的横截面与防撞梁主体的端部横截面相同;弱力区由至少一对间隔设置的焊缝组成,弱力区至防撞梁主体的中轴线的距离为d1;弱力区之间为防撞梁主体的形变区,形变区沿防撞梁主体的受力朝向形变,并形成距离为d2的侵入量。本发明的优点有:在防撞梁主体上设置三条焊缝以引导其产生形变,且防撞梁主体的形变量最小,进而使得防撞梁受碰撞后传递给车身的力量减小,有效减小对车声的损伤和对驾乘人员的人身安全的威胁。
