[0004] To this end, we propose a sound-absorbing and shock-absorbing foam. Utility Model Content

[0013] (3) Beneficial effects

[0014] Compared with the existing technology, the present invention provides a sound-absorbing and shock-absorbing foam with the following beneficial effects:

[0015] 1. This kind of sound-absorbing and shock-absorbing foam has a multi-layer structure design, which can improve noise reduction and shock resistance.

[0016] 2. This sound-absorbing and shock-absorbing foam is provided with a first sound-absorbing foam layer and a second sound-absorbing foam layer, and honeycomb holes are opened on the first sound-absorbing foam layer and the second sound-absorbing foam layer. The honeycomb hole design causes the sound waves to be reflected and refracted multiple times during the propagation process, thereby increasing the contact area and time between the sound waves and the material, thereby more effectively absorbing the sound wave energy and converting it into other forms of energy such as heat energy, thereby achieving the purpose of reducing noise. After the sound wave enters the honeycomb hole, it will be reflected and scattered multiple times inside the pore, causing the sound wave energy to be gradually converted into heat energy and dissipated. This energy conversion process effectively reduces the propagation and reflection of the sound wave, thereby achieving the sound absorption effect.

The upper part of the first shock-absorbing foam layer is longitudinally wavy, and the upper part of the second shock-absorbing foam layer is transversely wavy, so that it can absorb energy by bending and compressing when impacted, thereby improving the shock-absorbing performance.

[0018] 4. The sound-absorbing and shock-absorbing foam can improve its anti-slip properties by providing an anti-slip texture on the outer surface of the lower end of the bottom foam layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] This embodiment is a sound-absorbing and shock-absorbing foam.

[0026] like Figure 1-4 As shown, it includes a first sound-absorbing foam layer 1, the lower outer surface of the first sound-absorbing foam layer 1 is bonded with a first shock-absorbing foam layer 2, the lower outer surface of the first shock-absorbing foam layer 2 is bonded with a second sound-absorbing foam layer 3, the lower outer surface of the second sound-absorbing foam layer 3 is bonded with a second shock-absorbing foam layer 4, and the lower outer surface of the second shock-absorbing foam layer 4 is bonded with a bottom foam layer 5.

[0027] The first sound-absorbing foam layer 1 and the second sound-absorbing foam layer 3 have the same structure. The upper outer surfaces of the first sound-absorbing foam layer 1 and the second sound-absorbing foam layer 3 are both provided with honeycomb holes 6; the upper outer surface of the first shock-absorbing foam layer 2 is longitudinally wavy; the upper outer surface of the second shock-absorbing foam layer 4 is transversely wavy; the lower outer surface of the bottom foam layer 5 is provided with an anti-slip texture 7.

[0028] It should be noted that the present invention is a sound-absorbing and shock-absorbing foam. By setting a first sound-absorbing foam layer 1, a first shock-absorbing foam layer 2, a second sound-absorbing foam layer 3, a second shock-absorbing foam layer 4 and a bottom foam layer 5, the multi-layer structure design can improve noise reduction and shock resistance. By setting the first sound-absorbing foam layer 1 and the second sound-absorbing foam layer 3, honeycomb holes 6 are opened on the first sound-absorbing foam layer 1 and the second sound-absorbing foam layer 3. The design of the honeycomb holes 6 causes the sound waves to be reflected and refracted multiple times during the propagation process, increasing the contact area and time between the sound waves and the material, thereby more effectively absorbing the sound wave energy and converting it into other forms of energy such as heat energy. , achieving the purpose of reducing noise. After the sound wave enters the honeycomb hole 6, it will be reflected and scattered multiple times inside the pore, causing the sound wave energy to gradually be converted into heat energy and dissipated. This energy conversion process effectively reduces the propagation and reflection of the sound wave, thereby achieving the effect of sound absorption. By setting the first shock-absorbing foam layer 2 and the second shock-absorbing foam layer 4, the upper part of the first shock-absorbing foam layer 2 is longitudinally wavy, and the upper part of the second shock-absorbing foam layer 4 is transversely wavy, so that it can absorb energy by bending and compression when impacted, thereby improving the shock absorption performance. By arranging an anti-slip texture 7 on the outer surface of the lower end of the bottom foam layer 5, the anti-slip property can be improved.
