With the popularization of automobiles, people pay more attention to the maintenance cost and insurance cost of the automobiles, and especially pay more attention to the maintenance cost of the automobiles under low-speed collision. The vehicle maintenance economy is the maintainability of the vehicle in terms of physical conditions and cost. Generally, the smaller the number of damaged expensive high-value-added parts of an automobile, the lower the price of replacement parts, the fewer the man-hours for repair, and the better the repair economy of the automobile. Therefore, it is necessary to reduce damage to vulnerable parts in a low-speed collision of a vehicle, and particularly, to reduce damage to high value-added parts, thereby reducing maintenance costs.
If a good rear collision maintenance economy rating is desired, the rear collision-proof beam and the rear energy-absorbing box must be required to absorb energy sufficiently, parts behind the energy-absorbing box are protected from large impact and deformation, and particularly, the maintenance cost after collision of the rear longitudinal beam, the rear coaming and the rear floor is reduced. However, due to the influence of the shape and the length of the rear overhang, the energy absorption space at the rear end is limited and cannot be increased without limit. The traditional rear longitudinal beam connecting flange (the thickness is generally less than or equal to 1.8mm) is generally connected with the rear section of a rear longitudinal beam by adopting a fillet transition structure, and a mounting gap of about 9mm exists between the rear end surface of the rear longitudinal beam and the mounting plane of the rear enclosing plate in the X direction, so that the transmission of the collision force of the rear end structure is discontinuous. When the automobile bumps at the back, the flanging of the connecting flange of the back longitudinal beam and the fillet transition structure are easy to deform by extrusion, so that the flanging and the fillet transition structure invade the back longitudinal beam rear section, the back coaming and the back floor, and the back longitudinal beam rear section, the back coaming and the back floor are damaged. The cost of maintaining the rear longitudinal beam rear section, the back panel and the rear floor is very high, and the rear collision maintenance economy rating is greatly reduced.
