One end of the second spring 9 is fixedly connected to the right outer wall of the limit post 7. The other end of the second spring 9 is fixedly connected to the left outer wall of the second extrusion block 10. The outer wall of the second extrusion block 10 is rotatably connected with a rotating wheel 11. The outer wall of the rotating wheel 11 is rotatably connected to the outer wall of the connecting plate 5. The outer wall of the anti-collision strip 1 is provided with a connecting component for assisting in supporting the connecting plate 5.

[0024] Specifically, when the anti-collision strip 1 is subjected to an external impact, the impact force is transmitted through the anti-collision strip 1 to the first extrusion block 2, and at the same time, the hydraulic rod 3 and the first spring 4 are compressed. The first extrusion block 2 functions to extrude the second extrusion block 10. The second extrusion block 10 drives the rotating wheel 11 to slide on the connecting plate 5, and the second extrusion block 10 extrudes the second spring 9 to slide on the sliding column 8 to compress the second spring 9. The support block 6 functions to fix and limit the position of the limiting column 7.

[0025] Refer to Figure 2 and Figure 3 , the connecting component includes a connecting column 12. The outer wall of the connecting column 12 is fixedly connected to the outer wall of the anti-collision strip 1. A second limiting ring 15 is fixedly connected to the outer wall of the connecting column 12. A connecting cylinder 13 is slidably connected to the outer wall of the second limiting ring 15. A first limiting ring 14 is fixedly connected to the inner wall of the connecting cylinder 13. The outer wall of the connecting column 12 is slidably connected to the inner wall of the first limiting ring 14. A third spring 16 is fixedly connected to the outer wall of the second limiting ring 15. The third spring 16 is slidably connected to the inner wall of the connecting cylinder 13.

[0026] Specifically, the connecting column 12 drives the second limiting ring 15 to slide on the inner wall of the connecting cylinder 13, achieving the effect of compressing the third spring 16, and further buffering the impact force from the front. The first limiting ring 14 functions to limit the position of the second limiting ring 15.

[0027] Refer to Figure 1 , a first compression spring 17 is fixedly connected to the outer wall of the anti-collision strip 1, and the other end of the first compression spring 17 is fixedly connected to a baffle 18.

[0028] Specifically, the first compression spring 17 functions to connect the anti-collision strip 1 and the baffle 18.

[0029] Refer to Figure 2 and Figure 4 , a sliding rod 19 is fixedly connected to the outer wall of the connecting plate 5, and a fixing column 23 is fixedly connected to the inner wall of the sliding rod 19; a support rod 24 is rotatably connected to the outer wall of the fixing column 23, and a clamping block 25 is rotatably connected to the outer wall of the support rod 24; a second compression spring 26 is fixedly connected to the outer wall of the clamping block 25, and a fixing block 20 is slidably connected to the outer wall of the sliding rod 19; a limiting groove 22 is formed inside the fixing block 20, and the outer wall of the clamping block 25 is slidably connected to the inner wall of the limiting groove 22; an energy-absorbing buffer plate 21 is fixedly connected to the outer wall of the fixing block 20.

[0030] Specifically, the sliding rod 19 drives the sliding of the clamping block 25, so that it slides on the inner wall of the fixed block 20, achieving the effect of clamping the clamping block 25 in the limiting groove 22. The fixed column 23 plays a role in assisting the support of the support rod 24, and the second compression spring 26 plays a role in assisting the support of the clamping block 25.

[0031] Working principle: When the bumper needs to be used, if the anti-collision strip 1 is impacted, the impact force will be transmitted to the first extrusion block 2 through the anti-collision strip 1. While squeezing the hydraulic rod 3, the first spring 4 is compressed. Then, when the first extrusion block 2 squeezes the second extrusion block 10, the second extrusion block 10 drives the rotating wheel 11 to slide on the connecting plate 5. The second extrusion block 10 squeezes the second spring 9 to slide on the sliding column 8, and at the same time squeezes the second spring 9. The support block 6 plays a role in fixing the limiting column 7, and can also squeeze the connecting column 12. The connecting column 12 drives the second limiting ring 15 to slide on the inner wall of the connecting cylinder 13 while compressing the third spring 16, so as to buffer the frontal impact force. Under the combined action of the first compression spring 17 and the baffle 18, the side impact force can be buffered. The first limiting ring 14 plays a role in limiting the second limiting ring 15. When installing the energy-absorbing buffer plate 21, the sliding rod 19 drives the clamping block 25 to slide on the inner wall of the fixed block 20, so that the clamping block 25 is clamped in the limiting groove 22. The fixed column 23 plays a role in assisting the support of the support rod 24, and the second compression spring 26 plays a role in assisting the support of the clamping block 25, making it firmly clamped in the limiting groove 22. This bumper not only achieves the effect of effectively buffering the impact forces from all directions, but also achieves the effect of quickly docking and installing the energy-absorbing buffer plate 21.
