The invention belongs to the technical field of automobile safety, and discloses a translation energy absorption mechanism which comprises a first sliding module, a second sliding module and a first energy absorption module. The first sliding module comprises a first sliding rail, a first transmission part, a fixing seat, a first limiting assembly and a second limiting assembly, at least two second protrusions are arranged at the end, in the second direction, of the fixing seat, the second direction is perpendicular to the first direction, and the first limiting assembly comprises at least two first protrusions; the first protrusions are located on the peripheral side of the fixing base in the second direction and are opposite to the second protrusions in a one-to-one mode, the second protrusions abut against the corresponding first protrusions in a pressing mode, and the end faces, connected with the first protrusions, of the second protrusions are gradually away from the fixing base in the direction from the first limiting assembly to the second limiting assembly. One of the second protrusion and the first protrusion which correspond to each other can stretch out and draw back elastically. In the collision process, relative movement of the trunk and the head is effectively reduced through the translation energy absorption mechanism, and neck injuries of passengers are reduced.
本发明属于汽车安全技术领域,公开了一种平动吸能机构,其包括第一滑动模块、第二滑动模块和第一吸能模块。第一滑动模块包括第一滑轨、第一传动件、固定座、第一限位组件和第二限位组件,固定座在第二方向上的端部设有至少两个第二凸起,第二方向垂直于第一方向,第一限位组件包括至少两个第一凸起,各第一凸起位于固定座在第二方向上的周侧,且与各第二凸起一一相对,各第二凸起压抵在对应的第一凸起上,沿第一限位组件指向第二限位组件的方向,第二凸起和第一凸起相接的端面逐渐远离固定座,相互对应的第二凸起和第一凸起两者中的一者能够弹性伸缩。在碰撞过程中,平动吸能机构有效地降低了躯干和头部的相对运动,减少乘员颈部损伤。
