Technical Field
[0001] The utility model relates to the technical field of foam materials, and particularly relates to a foam material with good shockproof performance. Background Art
[0002] Foam is a material obtained by foaming plastic particles, abbreviated as foam. Foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, CR, EVA, cross-linked PE, SBR, EPDM, etc. Foam has a series of characteristics such as elasticity, light weight, quick pressure-sensitive fixation, easy to use, flexible bending, ultra-thin volume, and reliable performance.
[0003] However, the structure of traditional foam is single, and its shock absorption performance can only rely on the physical properties of its own structure to achieve the shock absorption effect. When encountering a strong impact, its shock absorption effect is limited and it cannot guarantee the safety of the protected item. Therefore, the utility model provides a foam material with good shockproof performance to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a foam material with good shockproof performance, which solves the technical problems of the single structure of traditional foam, whose shock absorption performance can only rely on the physical properties of its own structure to achieve the shock absorption effect, and when encountering a strong impact, its shock absorption effect is limited and it cannot guarantee the safety of the protected item.
[0005] The technical solution of the utility model is as follows:
[0006] A foam material with good shockproof performance includes a foam body. A tensile layer is embedded in the middle of the foam body. A number of first buffer air chambers are arranged in a matrix on the upper and lower surfaces of the tensile layer. The first buffer air chambers are communicated with the outside through a first air passage on one side of the foam body. Two second buffer air chambers are oppositely arranged on the left and right sides of the tensile layer. The second buffer air chambers are communicated with the outside through a second air passage on one side of the foam body. Two third buffer air chambers are oppositely arranged on the front and back sides of the tensile layer. The third buffer air chambers are communicated with the adjacent second air passages through a third air passage.
[0007] Further, the tensile layer is a fiberglass woven layer.
[0008] Further, anti-tensile copper wires arranged horizontally and vertically are embedded inside the fiberglass woven layer.
[0009] Further, the first buffer air chambers, the second buffer air chambers, and the third buffer air chambers are all hemispherical.
[0010] Further, a graphite layer is arranged on the upper surface of the foam body.
[0011] Further, the graphite layer is connected to the foam body through a heat-conducting adhesive layer.
[0012] Further, a heat dissipation layer is provided on the lower surface of the foam body.
[0013] Further, the heat dissipation layer is connected to the foam body through an adhesive layer.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] (1) By embedding a tensile layer in the middle of the foam body, the tensile layer is a glass fiber woven layer, and tensile copper wires arranged horizontally and vertically are embedded inside the glass fiber woven layer, thereby greatly enhancing the tensile resistance performance of the foam, making it not easy to deform inside;
[0016] (2) By arranging a first buffer air chamber, a second buffer air chamber, and a third buffer air chamber around the tensile layer, when subjected to external impact, the first buffer air chamber, the second buffer air chamber, and the third buffer air chamber will deform, and the air inside will be discharged to the outside from the air ducts on one side, thereby achieving a good shock absorption and buffering effect;
[0017] (3) By arranging a graphite layer and a heat dissipation layer on the upper and lower surfaces of the foam body, while using the foam body to prevent vibration, heat can be quickly dissipated, so that the heat dissipation effect and the vibration prevention effect can coexist.

[0020] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will further describe the present utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.
[0021] In order to illustrate the technical solutions described in the present utility model, the following will be illustrated through specific embodiments.
[0022] Embodiment
[0023] Please refer to Figure 1, this embodiment provides a foam with good shock resistance, which is composed of a graphite layer 1, a thermal conductive adhesive layer 2, a foam body 3, an adhesive layer 4, and a heat dissipation layer 5 from top to bottom. Among them, a tensile layer 6 is embedded in the middle of the foam body 3. A number of first buffer air chambers 7 are arranged in a matrix on the upper and lower surfaces of the tensile layer 6. The first buffer air chambers 7 communicate with the outside from one side of the foam body 3 through a first air passage 8. Two second buffer air chambers 9 are arranged opposite to each other on the left and right sides of the tensile layer 6. The second buffer air chambers 9 communicate with the outside from one side of the foam body 3 through a second air passage 10. Two third buffer air chambers 11 are arranged opposite to each other on the front and back sides of the tensile layer 6. The third buffer air chambers 11 communicate with the adjacent second air passage 10 through a third air passage 12. The first buffer air chambers 7, the second buffer air chambers 9, and the third buffer air chambers 11 are all hemispherical.
[0024] By embedding a tensile layer 6 in the middle of the foam body 3, the tensile layer 6 is a glass fiber woven layer, and anti-tensile copper wires arranged horizontally and vertically are embedded inside the glass fiber woven layer, thereby greatly enhancing the anti-tensile performance of the foam and making it not easy to deform internally.
[0025] By arranging the first buffer air chambers 7, the second buffer air chambers 9, and the third buffer air chambers 11 around the tensile layer 6, when subjected to an external impact, the first buffer air chambers 7, the second buffer air chambers 9, and the third buffer air chambers 11 will deform, and the air inside will be discharged to the outside through the air passage on one side, thereby achieving a good shock absorption and buffering effect. After the shock absorption and buffering are completed, the first buffer air chambers 7, the second buffer air chambers 9, and the third buffer air chambers 11 will automatically recover under the action of the material structure of the foam body 3 itself.
[0026] By arranging the graphite layer 1 and the heat dissipation layer 5 on the upper and lower surfaces of the foam body 3, the graphite layer 1 conducts the external heat to the foam body 3 through the thermal conductive adhesive layer 2, and then conducts it to the heat dissipation layer 5 on the other side through the adhesive layer 4 for heat dissipation, so that heat dissipation can coexist with the shockproof effect.
[0027] The above is only a preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
