The invention relates to the technical field of vehicle safety, in particular to an instrument panel cross beam collision collapse mechanism which comprises a vehicle body connecting piece, a steering column mounting piece, an instrument panel cross beam and two rigid supporting pieces, the steering column mounting piece comprises a first mounting plate, and a first mounting part and a second mounting part are arranged at the two ends of the first mounting plate correspondingly; each rigid supporting piece comprises a first supporting plate, a second supporting plate is arranged at one end of each first supporting plate, a crumple part is arranged on each second supporting plate, and through the crumple parts on the second supporting plates, the collision impact force is weakened at the crumple parts, and the crumple parts are bent and deformed, so that the effect of counteracting the collision impact force is achieved; therefore, collision impact force cannot be transmitted to the tubular column support, a steering wheel on the tubular column support is prevented from hurting a driver, and the problems that in the collision process of an existing instrument panel beam steering mechanism on the front face of a vehicle body, the invasion amount is large, the living space of passengers is small, and the safety performance is reduced are solved.
本发明涉及车辆安全技术领域,具体涉及一种仪表板横梁碰撞溃缩机构,包括车身连接件、转向管柱安装件、仪表盘横梁和两个刚性支撑件,所述转向管柱安装件包括第一安装板,所述第一安装板的两端分别设有第一安装部和第二安装部,每个所述刚性支撑件均包括第一支撑板,所述第一支撑板的一端设有第二支撑板,所述第二支撑板上设有溃缩部,通过第二支撑板上的溃缩部,使碰撞冲击力在溃缩部减弱,并使溃缩部折弯变形,以达到抵消碰撞冲击力的效果,从而使碰撞冲击力无法传递到管柱支架上,避免了管柱支架上的方向盘对司机进行伤害,解决了现有的仪表板横梁转向机构在车身正面遇到碰撞过程中,存在侵入量大,导致乘客生存空间小和安全性能降低的问题。
