The invention relates to the technical field of automobile chassis, in particular to an automobile chassis with an impact protection function and a using method, and the automobile chassis comprises a frame formed by welding longitudinal beams located on the two sides and a plurality of cross beams. According to the automobile chassis with the collision protection function and the using method, a deformed anti-collision beam abuts against and pushes a column casing and a plate base through a connecting rod and moves backwards along an embedded plate through a transverse shaft, a sliding column compresses a spring along the moving column casing to form relative forward movement, and an inclined fin synchronously moves along with the sliding column and abuts against and pushes a tail cone of U-shaped steel; the front end of the U-shaped steel is slightly lifted to break back balance of the tension spring, the tension spring is used for pulling the U-shaped steel to further deflect until the U-shaped steel is limited to be in a vertical state by the plate seat, at the moment, the U-shaped steel, the main body and the plate seat form an L-shaped blocking frame at the front end of the frame and beside the engine, and the frame with the maximum strength serves as an acting point to resist impact transmitted from the head of the bicycle. The direct collision force of the engine in the engine compartment can be effectively reduced, and potential safety hazards caused by the fact that the engine moves backwards and impacts a passenger compartment are avoided.
本发明涉及汽车底盘技术领域,具体为一种具有撞击保护功能的汽车底盘及使用方法,包括由位于两边的纵梁和若干根横梁焊接组成的车架。该种具有撞击保护功能的汽车底盘及使用方法,通过变形的防撞梁通过连杆抵推柱筒及板座利用横轴沿嵌板后移,滑柱沿移动的柱筒压缩弹簧形成相对前移,斜鳍跟随滑柱同步移动并抵推U形钢的尾锥,使U形钢前端微抬打破拉簧回拉的平衡,并利用拉簧拉动U形钢进一步偏转,直至U形钢被板座限位为竖立状态,此时U形钢与主体、板座在车架前端、发动机旁形成L形的挡架,并以强度最大的车架作为着力点抵抗车首传来的冲击,可有效降低发动机舱内的发动机直接受撞力度,避免发动机后移冲击乘员舱造成安全隐患。
