[0046] The collapse plate 12 is arranged inside the edge of the buffer plate 5, one side of the collapse plate 12 is fixed with the inner wall of the buffer plate 5, the other side of the collapse plate 12 is fixed with the inner bulge 3 at the corresponding position, and the upper surface and the lower surface of the collapse plate 12 are both provided with a plurality of energy absorption grooves 13 in a staggered distribution;

[0047] In the embodiment, the secondary energy absorption assembly comprises:

[0048] The energy absorption box 15 is arranged between the outer bulge 2 and the support column 14, one side of the energy absorption box 15 is fixed with the back side of the outer bulge 2, the energy absorption box 15 has a hollow structure, the inner cavity of the energy absorption box 15 is welded and fixed with the collapse induction plate 16, the mounting plate 17 is fixed at the corresponding position of the support column 14 and the energy absorption box 15, the mounting plate 17 is provided with the mounting hole for being fixed with the energy absorption box 15, and the energy absorption box 15 is fixed with the mounting plate 17 through the bolts.

[0049] The buffer layer 6 is made of ACF material, the ACF material has a unique micro-nano structure, when the impact force attacks, the micro-nano structure can not be “surrendered”, but deformed rapidly, and the impact energy is layer by layer disassembled and absorbed, like “soft overcomes hard” in Tai Chi, so that the violent impact is invisible, has a strong energy absorption effect, and can absorb most of the potential energy generated by the impact in an instant when the vehicle collides with the device, the ACF material not only has excellent energy absorption, but also has excellent resilience, can quickly restore to the original state, and is ready to meet the next impact at any time; it is worth noting that the ACF material is prior art, and those skilled in the art should be familiar with it, and the present application will not be described in more detail; compared with traditional materials such as rubber material and EVA material, according to the strict ASTM F1614 measurement method, the ACF material can absorb more than 90% of the impact force, and even the maximum value can reach 97.1%, which is much higher than traditional rubber and EVA materials, and the internal stable molecular structure of the ACF material makes it not afraid of friction loss, and the service life is greatly prolonged, in addition, the ACF material is lighter, so that the weight of the device can be reduced;

[0050] When the collision occurs, the buffer layer 6 absorbs the potential energy generated by the collision first, then the excess impact force pushes the buffer layer 6 and the buffer plate 5 to displace inward, and acts on the plurality of buffer assemblies, under the action of the plurality of buffer assemblies, most of the impact force can be extremely effectively absorbed, and the small distributed impact force is transmitted to the rear energy absorption box 15 through the outer protrusion 2, under the action of the energy absorption box 15, the crush inducing plate 16 and the support column 14, the remaining impact force can be approximately completely absorbed, and the trace impact force is transmitted to the ground through the support column 14 for absorption.

[0054] Wherein, referring to the accompanying drawings Figure 1 And 2 The outer protrusion 2 and the inner protrusion 3 are supported by steel materials, and the surfaces are uniformly coated with a layer of anti-rust coating, due to the W-shaped structure of the outer protrusion 2 and the inner protrusion 3, the grooves of the outer protrusion 2 and the inner protrusion 3 can absorb the energy generated by the impact, which can further weaken the adverse consequences caused by the impact.

[0059] By setting the spring 10 to absorb the pressure generated when the buffering plate 5 displaces inwardly, the effective rigid contact between the buffering plate 5, the buffering layer 6 and the vehicle is reduced, and the impact potential energy generated during the collision is greatly weakened.
