The invention provides an automobile anti-collision beam skeleton assembly. The automobile anti-collision beam skeleton assembly comprises a steel bumper skeleton transverse beam, two aluminum energy absorption boxes and two bottom plates, wherein the two aluminum energy absorption boxes are arranged at the two ends of the bumper skeleton transverse beam respectively, and the two bottom plates are arranged at the bottom ends of the two aluminum energy absorption boxes respectively. The weight of the automobile anti-collision beam skeleton assembly is about 15%-40% that of an existing steel automobile anti-collision skeleton assembly, and is equal to that of an existing full-aluminum automobile anti-collision skeleton assembly, in this way, the weight is effectively reduced, and functions can still be effectively brought into play. In addition, the anti-collision transverse beam is not likely to crack after being collided, existing laser cutting can be adopted for hole position machining, an existing technology is adopted for welding supports to the anti-collision transverse beam, the machining cost is low, the machining technology is mature, and the automobile anti-collision beam skeleton assembly is suitable for application and popularization.
