The middle of the shock-absorbing plate 2 is composed of polyurethane components, which can withstand higher loads and impact forces. At the same time, the shock-absorbing plate 2 is connected to the installation sub-frame 3 through the connecting frame 22, the transverse frame 23, and the installation sub-frame 3, which can reduce the impact force on the installation sub-frame 3.
