The invention discloses an unmanned vehicle collision energy absorption device which comprises a front baffle, a telescopic rod, a telescopic cylinder, a fixed cylinder and a base, by arranging two-stage energy absorption structures, when slight collision occurs, only the first-stage energy absorption structure absorbs energy, in the state, the front baffle slightly moves backwards and recovers after a vehicle is moved away, and damage to the front baffle caused by collision is reduced. However, when kinetic energy during collision is large, the second-stage energy absorption structure can be triggered to absorb energy, and the front baffle can further move backwards. And when the kinetic energy is larger during collision, the secondary energy absorption mechanism directly releases all energy and triggers the emergency braking assembly to help the vehicle stop and reduce the damage caused by collision.
本发明公开一种无人车碰撞吸能装置,包括前挡板、伸缩杆、伸缩筒、固定筒和基座,通过设置二级吸能结构,在轻微碰撞时,仅仅第一级吸能结构进行吸能,此状态下,前挡板会略微后移,并在车辆移开后恢复,减小碰擦造成的前挡板损坏。但碰撞时的动能较大时,会触发第二级吸能结构进行吸能,使得前挡板会进一步后移。而在碰撞时的动能更大时,二级吸能机构直接释放掉所有能量,并触发紧急制动组件,帮助车辆停止,减小碰撞造成的伤害。
