The main function of the buffer structure provided is to absorb and mitigate external impact forces, reduce the damage suffered by the vehicle during a collision or impact event, and protect the safety of the occupants.

[0003] In the prior art, the publication number CN220562679U was proposed. The technical solution disclosed in this patent document is as follows: an energy-absorbing bumper, including an insurance substrate and a mounting component. Installation connection blocks are arranged at both the left and right ends of the top of the insurance substrate. The mounting component is arranged inside the front wall of the insurance substrate, and installation components are arranged at both the left and right ends of the bottom of the mounting component. The installation component includes an installation clamping block and a fastening screw hole, and a fastening screw hole is arranged inside the installation clamping block. Compared with the existing bumpers, this energy-absorbing bumper further improves the protection performance of the bumper and the safety factor by setting the mounting component and the installation component to install on the front end of the insurance substrate, and a limit buffer component and an energy-absorbing component that can be limited are arranged on the inner side for energy-absorbing connection, thereby improving the buffer capacity of the device.

[0004] The above technical solution provides buffer energy absorption protection by setting a buffer component on the insurance substrate, but does not provide buffer protection for both sides of the insurance substrate. Since the impact on the vehicle may come from the front or the side, and no buffer component is arranged on both sides of the insurance substrate, the overall deformation and damage ability of the bumper is increased.
