The invention provides a rear bumper cross beam assembly structure, and relates to the technical field of rear bumpers, the rear bumper cross beam assembly structure comprises a cross beam body, a vehicle tail body and a vehicle tail plate, collision buffers are fixed at two ends of the cross beam body, connecting bolts are connected to four corners of each collision buffer in a penetrating manner, and a supporting block is fixed on one side of the cross beam body. A supporting rod is fixed to one side of the supporting block. According to the device, when the tail of a vehicle is collided, the vehicle tail plate moves towards the cross beam body, the included angle between every two adjacent first connecting rods is increased, the two movable sleeve blocks diffuse towards the two ends, the springs are stretched, the three first connecting rods are connected through the second connecting rods, and therefore no matter the upper portion or the lower portion of the vehicle tail plate is collided, the vehicle tail plate can be fixed; when the collision buffer is used, the three groups of first connecting rods can move simultaneously, and the three springs can be stretched simultaneously, so that the energy of the tail plate is primarily absorbed, and the effect of buffering the collision while the collision buffer absorbs the energy is achieved.
本发明提供一种后保险杠横梁总成结构,涉及后保险杠技术领域,包括横梁体、车尾体和车尾板,所述横梁体两端均固定有碰撞缓冲器,所述碰撞缓冲器四角均贯穿连接有连接螺栓,所述横梁体一侧固定有支撑块,所述支撑块一侧固定有支撑杆。本装置在车辆尾部受到撞击时,车尾板向横梁体处移动,相邻两个第一连接杆之间的夹角进行增大,两个移动套块向两端扩散,对弹簧进行拉伸,通过第二连接杆将三个第一连接杆进行连接,使得在车尾板无论是上方或是下方受到撞击,三组第一连接杆均会同时进行移动,三根弹簧也会同时进行拉伸,对车尾板的能量进行初步吸收,从而达到在碰撞缓冲器吸能的同时进行撞击缓冲的效果。
