[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] The elastic foam, such as Figure 1-Figure 3As shown, it includes, from top to bottom, a protective layer 1, an antistatic layer 2, a waterproof layer 3, an elastic layer 4, and a base layer 5. The protective layer 1 is made of high-strength non-transparent polyester fiber material with a thickness of 0.05-0.1mm. Polyester fiber has extremely high strength and wear resistance and can effectively resist scratches and wear from external objects. For the components inside the electronic product, the protective layer 1 can provide the first line of defense to protect the internal components of the product from damage. The antistatic layer 2 can effectively prevent static electricity from damaging sensitive components inside the electronic product. During the use of the electronic product, static electricity may cause damage to the electronic components, data loss, and even device failure. The antistatic layer 2 is made of a special conductive polymer material, which can promptly conduct static electricity to ensure the normal operation of the electronic product. The waterproof layer 3 is made of a polymer waterproof material with a thickness of 0.1- 0.2mm, the polymer waterproof material selected here can be a polyolefin material, which has excellent waterproof performance and can effectively prevent moisture from penetrating into the inside of the foam, thereby protecting the internal components of the electronic products. Even in a humid environment, the electronic products can maintain normal operation. The base layer 5 is made of thermoplastic elastomer material. Thermoplastic elastomer has good flexibility and elasticity, and can provide stable support for the foam. At the same time, the thermoplastic elastomer also has good processing performance and can be easily bonded and compounded with other layers.

[0018] like Figure 1-Figure 3As shown, the elastic layer 4 is composed of a plurality of arc blocks 7. The arc blocks 7 have elastic deformation properties and can deform when subjected to external force, absorb impact force, and provide buffer protection for electronic products. The arc blocks 7 are made of thermoplastic polyurethane elastomer rubber material. This material has high elasticity and good resilience. It can quickly return to its original shape after being impacted, providing continuous protection for electronic products. Long strips 8 are provided between the contact surfaces of the arc blocks 7 and the reinforcing layer 6 and the base layer 5 respectively. The waterproof layer 3 generally has low strength. The reinforcing layer 6 is used to increase the contact area between the waterproof layer 3 and the long strips 8. The reinforcing layer 6 is made of glass fiber mesh cloth material. Glass fiber has extremely high strength and modulus. The long strips 8 and the arc blocks 7 are integrally formed. The long strips 8 not only enhance the structural stability of the foam, but also can disperse stress when subjected to external force, thereby improving the overall compressive resistance of the foam. , the long strip 8 is made of high-strength plastic material with certain toughness and rigidity. A plurality of springs 9 are fixedly connected between each arc block 7 and the base layer 5. A receiving cavity 12 is provided on the side of the arc block 7 facing the base layer 5. One end of the spring 9 is adhered to the receiving cavity 12, and the other end is adhered to the base layer 5. Since the cross-section of the arc block 7 is arc-shaped, the receiving cavity 12 can provide a horizontal surface for connection with the spring 9, which is convenient for fixing the spring 9. The spring 9 can further enhance the elastic properties of the foam. When the electronic product is subjected to a large impact force, the spring 9 can absorb more energy and protect the internal components from damage. A plurality of anti-pressure parts 10 are fixedly connected between adjacent arc blocks 7. Connecting rods 11 are provided at both ends of the anti-pressure part 10. The connecting rod 11 is fixedly connected to the side of the arc block 7. The connecting rod 11 is used to fix the anti-pressure part 10 between adjacent arc blocks 7. The anti-pressure part 10 is "o" The shape of the ring is 3-5mm in width and is made of high-strength rubber material. The rubber is nitrile rubber with good pressure resistance and wear resistance. The pressure-resistant part 10 can provide additional support and pressure resistance when the foam is under pressure. When the electronic product is squeezed or pressed by a heavy object, one side of the foam is squeezed and the compressed arc block 7 is deformed to one side. The pressure-resistant part 10 can transfer part of the pressure to the remaining arc blocks 7 and deform inward under pressure. The pressure-resistant part 10 can further prevent the foam from excessive deformation and protect the internal components from damage.
