The invention discloses a collision energy absorption mechanism which comprises a collision energy absorption device. The collision energy absorption device comprises a supporting frame and an energy absorption mechanism. Energy absorption mechanisms are arranged on the supporting frame, the supporting frame can drive the energy absorption mechanisms to deform, and at least one energy absorption mechanism is arranged on the supporting frame. The energy-absorbing device has the beneficial effects that when the energy-absorbing device is collided, the supporting frame can drive one end of the energy-absorbing mechanism to move, so that the bending energy-absorbing assembly is stretched to absorb energy, and the bending energy-absorbing assembly can be torn through the secondary stretching part; by means of the device, large deformation and movement can be generated in the frontal collision of the truck cab, the peak value of the collision acceleration borne by passengers in the collision process is reduced, the risk that the passengers are clamped in the cab in a collision accident is reduced, the collision safety performance is improved, the energy absorption mechanism is allowed to generate specific large deformation, and the safety performance is improved. Therefore, collision energy can be absorbed together with the cab body, and the connection between the cab and the chassis can be maintained.
本发明公开了一种碰撞吸能机构,包括碰撞吸能装置;碰撞吸能装置包括支撑架,以及吸能机构;支撑架上设置吸能机构,支撑架可带动吸能机构进行形变,支撑架上至少设置一组吸能机构。本发明的有益效果为在受到碰撞时,支撑架可以带动吸能机构的一端进行运动,使折弯吸能组件进行拉伸吸收能量,并且通过二次拉伸件可以对折弯吸能组件进行撕裂,通过本装置可以在卡车驾驶室正面碰撞中可以产生较大的变形和移动,减少乘员在碰撞过程中受到的碰撞加速度的峰值,减少在碰撞事故中乘员被卡在驾驶室中的风险,提高了碰撞安全性能,本发明允许该吸能机构产生特定的大变形,从而和驾驶室本体共同吸收碰撞能量,同时又保证驾驶室和底盘维持连接作用。
