By dividing the energy-absorbing structural units into independent units, Each energy-absorbing component can function independently and effectively absorb collision energy instead of relying on each other, which improves the stability and reliability of the energy-absorbing effect. At the same time, it adopts a connection method different from the traditional bolting, which reduces the cumbersome bolting operation and makes the connection between the components simpler and more efficient. A D-shaped energy-absorbing barrel 6 and an arc-shaped guide plate 7 are welded to the outside of one of the fixing frames 4. The arc-shaped guide plate 7 is arranged on the outside of the D-shaped energy-absorbing barrel 6. By setting the D-shaped energy-absorbing barrel 6 and the arc-shaped guide plate 7, it can contact the vehicle first. The D-shaped energy-absorbing barrel 6 can effectively absorb the collision energy through its own structure and material properties, reduce the impact force of the collision on the vehicle and personnel, and the arc-shaped guide plate 7 can guide the vehicle to move in a predetermined direction, reducing loss of control and secondary injuries after the collision.

The bottoms of the damping rod 15 and the buffer spring 16 are fixedly connected with movable blocks 17, and the damping rod 15 and the buffer spring 16 absorb and slow down the collision energy through their own deformation, reduce the impact force of the collision on the vehicle and personnel, and improve the protective performance of the anti-collision pad bracket.
