The embodiment of the invention provides an energy-absorbing outer cover, a carriage and a railway vehicle. The energy-absorbing outer cover comprises a cover body, the cover body comprises a first-stage energy-absorbing cover body and a circumferential cover body; the cross sectional area of the first-stage energy-absorbing cover body is gradually increased in the longitudinal direction, and the cavity wall of the first-stage energy-absorbing cover body is transited through a smooth curved surface from the center to the circumferential edge; the circumferential cover body is located at the rear end of the first-stage energy-absorbing cover body, the circumferential cover body extends backwards in the longitudinal direction, and the cross sectional area of the circumferential cover body is gradually increased in the longitudinal direction; and a hollow cavity with an opening in the rear end is formed by the first-stage energy-absorbing cover body and the circumferential cover body so as to cover the front end of a vehicle body. The cover body forms a deformation energy absorption area through the first-stage energy-absorbing cover body and the circumferential cover body, impact borne by a vehicle body is buffered and absorbed, so that an energy absorption structure in the front end outer cover is omitted, the number of the energy absorption structures is reduced, and the space occupancy rate is reduced; and the vehicle body is ensured to be a non-deformation area through orderly progressive deformation failure energy absorption of the energy absorption outer cover, and the safety of a driver and passengers is ensured.

    本申请实施例中提供了一种吸能外罩、车厢及轨道车辆,吸能外罩包括罩体,罩体包括:第一级吸能罩体,第一级吸能罩体的横截面积沿纵向逐渐增大,第一级吸能罩体的腔壁自中心至周向边缘经光滑曲面过渡;周向罩体,周向罩体位于第一级吸能罩体的后端,周向罩体沿纵向向后延伸,且周向罩体的横截面积沿纵向逐渐增大;第一级吸能罩体和周向罩体形成后端开口的中空腔体,以对车体前端进行罩设。罩体通过第一级吸能罩体和周向罩体形成变形吸能区,对车体承受的冲击进行缓冲吸能,以省去前端外罩内的吸能结构,减少吸能结构的结构数,减少空间占有率;通过吸能外罩的有序渐进变形失效吸能保证车体为不变形区,保证司机和乘客安全。
