Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0026] In this embodiment, the EVA board structure 2 includes an EVA board body 201 , and a flame retardant layer 202 is fixed to the outer side of the EVA board body 201 . The flame retardant layer 202 can play a flame retardant role and conveniently protect the EVA board body 201 .

[0027] Furthermore, a wear-resistant layer 203 is fixed to the outer side of the flame-retardant layer 202 . The wear-resistant layer 203 has a wear-resistant property, making the EVA board body 201 more durable.

[0028] Example 2

[0029] On the basis of Example 1, the preferred embodiment of the flame retardant high-density EVA board for mining trucks provided by the present invention is as follows: Figures 2 to 3 As shown,

[0030] In this embodiment, a group of every two buffer spring sheets 3 is provided, and several groups of buffer spring sheets 3 are provided. The two buffer spring sheets 3 in each group are symmetrically arranged to facilitate the buffering effect.

[0031] In this embodiment, the air holes 4 are distributed on the EVA plate structure 2 in a rectangular array. The air holes 4 can be used for air intake and exhaust, and the air intake holes and the exhaust holes are distributed one by one in an alternating manner.

[0032] Furthermore, a connecting elastic rope 5 is fixed on the EVA plate mechanism 2, and a sealing cover 6 is fixed to the end of the connecting elastic rope 5. The sealing cover 6 is arranged one-to-one with the air hole 4, and the buffer spring piece 3 is retractable to facilitate the buffering effect. When the buffer spring piece 3 is compressed, external air can enter between the heat conducting plate 1 and the EVA plate mechanism 2 through the air inlet hole. At this time, the corresponding sealing cover 6 automatically opens. When the buffer spring piece 3 is extended, the sealing cover 6 on the exhaust hole automatically opens, which is convenient for smooth exhaust.

The buffer spring 3 supports the heat conducting plate 1 and the EVA board structure 2, which facilitates the buffering effect. When the buffer spring 3 is used for buffering, some of the pores 4 will be used as air inlets, and the external air can break through the cover 6 and enter between the heat conducting plate 1 and the EVA board structure 2. Another part of the pores 4 will be used as air outlets, and the gas between the heat conducting plate 1 and the EVA board structure 2 will break through the corresponding cover 6 and be discharged, thus completing the entire work.
