[0003] However, the above patent has certain shortcomings in the actual installation process. A large number of first through holes and second through holes are formed between the middle steel plate and the friction plate.

When the energy absorber is recycled and replaced, the numerous bolts must be removed one by one, which makes the disassembly and assembly efficiency of the energy absorber low. Therefore, it is necessary to design a new composite energy absorber to solve this problem. Utility Model Content
