After the force-bearing block is impacted, the impact force is transmitted to the ball head, and the ball head will be displaced. Due to the change of radius, the tile block will be squeezed out, and the retreat path of the tile block The upper part is resisted by the fixing plate from behind, and this part of the supporting force is transmitted to the ball head. In practice, however, the pavement structure comprises a plurality of units, and each unit adopts the above-mentioned structure. On the one hand, it prevents the impact force from continuing to pass forward. On the other hand, it changes the direction of the impact force vertically, and unloads the force in a way of diffusion and direction change, and the effect of unloading force is good.

As a preference of the present invention, the tile is provided with a force-receiving surface conforming to the shape of the ball head.

As a preference of the present invention, friction pads are provided on the force-bearing surface.

In summary, the present invention has the following beneficial effects:

1. The Y-shaped anti-collision bar divides the entire side door assembly into three stress-bearing triangular parts, which are stable in force and strong in deformation resistance.

2. The reinforced anti-collision plate has high impact resistance and structural strength.

3. The secondary anti-collision plate protects the lock part of the car door.

4. The force paving structure can prevent the impact force from continuing to be transmitted forward. On the other hand, the force direction of the impact force is changed vertically, and the force is unloaded in a way of diffusion and direction change, and the force unloading effect is good.
