The invention discloses a collision energy absorption device and a tramcar, and belongs to the technical field of rail vehicle energy absorption, the collision energy absorption device comprises a connecting plate, an anti-collision mechanism, a first buffer mechanism, a moving plate group, a second buffer mechanism and a third buffer mechanism; the first buffering mechanism is arranged on one side of the connecting plate and connected with the anti-collision mechanism. The movable plate group is arranged on the other side of the connecting plate and moves parallel to the connecting plate in the same direction; the second buffer mechanism is arranged on the connecting plate and is on the same side with the movable plate group; the third buffering mechanism limits the anti-collision mechanism to move perpendicular to the connecting plate. Longitudinal buffering of the anti-collision mechanism is achieved through the third buffering mechanism, the first buffering mechanism can drive the anti-collision mechanism to move relative to the connecting plate in the transverse direction, the movable plate set and the second buffering mechanism can drive the third buffering mechanism to move relative to the connecting plate in the transverse direction, and the impact force from the inclined side of the vehicle running direction can be effectively reduced; and transverse shaking of the vehicle body after being impacted is reduced.
本发明公开了一种碰撞吸能装置及有轨电车,属于轨道车辆吸能技术领域,一种碰撞吸能装置,包括:连接板、防撞机构、第一缓冲机构、移动板组、第二缓冲机构和第三缓冲机构;所述第一缓冲机构设于连接板一侧并与防撞机构相连;所述移动板组设于连接板另一侧并平行于连接板同向移动;所述第二缓冲机构设于连接板并与移动板组同侧;所述第三缓冲机构限位防撞机构垂直于连接板移动。本发明通过第三缓冲机构实现了防撞机构在纵向的缓冲,第一缓冲机构可带动防撞机构在横向上相对连接板移动、移动板组和第二缓冲机构可带动第三缓冲机构在横向上相对连接板移动,能够有效降低来自车辆行驶方向斜侧的撞击力,降低车体受到撞击后的横向晃动。
