The tramcar collision energy absorption structure comprises a front beam and a rear beam, the rear end of the front beam is connected with the front end of the rear beam, an upper row of square pipes and a lower row of square pipes are welded and fixed to the rear wall of the front beam and the two side walls of the interior of the rear beam correspondingly, and first energy absorption boxes are fixedly installed at the positions, close to the two ends, of the rear portions of the square pipes of the rear wall of the front beam correspondingly; a reinforcing frame is fixedly connected to the rear walls of the two first energy absorption boxes, a buffering box is arranged in the front of the reinforcing frame in a penetrating mode, second energy absorption boxes are connected between the two sides of the reinforcing frame and the two side walls of the interior of the rear beam, and a plurality of spring shock absorbers are connected between the rear wall of the buffering box and the rear wall of the interior of the reinforcing frame at equal intervals. An air bag assembly is mounted on the rear wall of the buffer box; according to the anti-collision device for the tramcar, the buffering support is arranged to be matched with the buffering box and the air bag assembly, when the tramcar is collided, multi-stage buffering can be carried out, energy absorption protection is effectively carried out, and the anti-collision effect of the tramcar is improved.

    本发明公开了一种有轨电车碰撞吸能结构,包括前梁与后梁,所述前梁的后端与后梁的前端相连接,所述前梁的后壁以及后梁的内部两侧壁均焊接固定有上下两排方形管,前梁后壁的方形管的后部靠两端位置均固定安装有吸能盒一,且两个吸能盒一的后壁固定连接有加固框,贯穿加固框的前部设置有缓冲盒,且加固框的两侧与后梁的内部两侧壁之间均连接有吸能盒二,缓冲盒的后壁与加固框的内部后壁之间等距连接有若干个弹簧减震器,且缓冲盒的后壁安装有气囊组件;本发明通过设置了缓冲支架配合缓冲盒与气囊组件,在有轨电车受到碰撞时,可进行多级缓冲,有效的进行吸能保护,提高了有轨电车的防碰撞效果。
