The invention relates to the technical field of automobile safety accessories, and provides an energy absorption device, a rear protection device and a vehicle. The energy absorption device comprises at least one set of main energy absorption parts, and each main energy absorption part comprises an outer skin of a pipeline structure and provided with a first energy absorption space and a supporting structure arranged on the side wall of the outer skin in a surrounding mode and forming a second energy absorption space; the adapter plate and the mounting plate are arranged at two opposite end parts of the outer skin; a separation structure is arranged in at least one second energy absorption space in the direction from the mounting plate to the adapter plate, and the separation structure is connected to the outer skin and the supporting structure and divides the second energy absorption space into a plurality of energy absorption subspace areas. According to the invention, impact and energy generated by collision are effectively reduced; when the energy absorption device is used for the tail of a large vehicle such as a tank car, damage to a front vehicle body during rear-end collision can be reduced, the energy absorption device can achieve energy absorption blocking through deformation buffering, loss is further reduced, and leakage of hazardous chemicals caused by structural damage of the tank is avoided.

    本发明涉及汽车安全配件技术领域,提供一种吸能装置、后防护装置及车辆,其中,吸能装置包括至少一组主吸能件,主吸能件包括呈管道结构且具有第一吸能空间的外蒙皮、围设于外蒙皮的侧壁且形成第二吸能空间的支撑结构,以及设置于所述外蒙皮的相对两端部的转接板和安装板;至少一个第二吸能空间内自安装板至转接板方向上设置有分隔结构,分隔结构连接于外蒙皮和支撑结构,且将第二吸能空间分隔形成多个吸能子空间区域。本申请有效地降低了碰撞产生的冲击和能量;当吸能装置用于槽罐车等大型车辆的尾部时,还能够降低追尾碰撞时前车车体的损坏,吸能装置能够通过变形缓冲来实现吸能阻拦,进一步地降低损失,避免槽罐结构破损而导致危化品的泄漏。
