The invention provides an end wall plate which comprises a back plate and door stand columns, the door stand columns are fixedly connected to the two sides of the back plate 1, a door upper cross beam is fixedly connected between the two door stand columns, the top of each door stand column is fixedly connected with an end top camber beam, and the bottom of each door stand column is fixedly connected with a bottom beam. The front face of the back plate is movably connected with a rebounding assembly used for providing buffering, the rebounding assembly comprises a front end frame, a first sliding groove, a first elastic plate and a first restoring spring, the first sliding groove is formed in the side, opposite to the door stand column, of the front end frame, and the first sliding groove makes contact with the front face of the first elastic plate. Deformation of the first elastic plate, the second elastic plate and the third elastic plate can be recovered, continuous deformation energy absorption of the first elastic plate, the second elastic plate and the third elastic plate is achieved, meanwhile, impact force borne by the front end frame can be dispersed and buffered, and the risk that the rear end frame and the structure of a vehicle body deform due to impact is reduced.

    本发明提供一种端墙板,包括背板和门立柱,所述门立柱固定连接在所述背板1的两侧,两个所述门立柱之间固定连接有门上横梁,所述门立柱的顶部固定连接有端顶弯梁,所述门立柱的底部和底梁固定连接,其特征在于,所述背板的正面活动连接有用于提供缓冲的回弹组件,所述回弹组件包括前端框架、第一滑槽和第一弹性板以及第一恢复弹簧,所述前端框架相对所述门立柱的一侧开设有第一滑槽,所述第一滑槽和第一弹性板的正面接触。本发明利用第一弹性板和第二弹性板以及第三弹性板的变形可以恢复,实现第一弹性板和第二弹性板以及第三弹性板的连续变形吸能,同时可以分散缓冲前端框架受到的撞击力,降低后端框架和车体的结构受到撞击变形的风险。
