[0003] Currently, some car vibration damping and sound insulation pads on the market adopt a relatively simple structural design. They are commonly made of a single material or a simple composite material, such as relying solely on ordinary rubber or sponge materials. They achieve vibration damping and sound insulation functions through their own elasticity and certain sound absorption capabilities. In terms of technical principle, they mainly utilize the physical properties of the material itself. When subjected to vibration, the material undergoes elastic deformation to buffer the vibration. When sound travels to the material, some of the energy is absorbed by the material, thereby reducing noise.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model is provided: a car shock absorption and sound insulation pad, including a wrapping layer 1, a wrapping layer 2 12 slidably connected to the lower surface of the wrapping layer 1, a buffer sound insulation component provided on the inner wall of the wrapping layer 1, and a disassembly component provided on the outer wall of the wrapping layer 1.

[0026] The sound insulation and buffer assembly includes a sound insulation board 8. The outer wall of the sound insulation board 8 is set on the inner wall of the first wrapping layer 1. Sound insulation cotton 13 is fixedly connected to the inner wall of the sound insulation board 8. A cotton pad 9 is attached to the outer wall of the sound insulation board 8. A silicone plate 10 is attached to the outer wall of the cotton pad 9. A rubber plate 11 is attached to the outer wall of the silicone plate 10. A spring 15 is fixedly connected to the lower surface of the second wrapping layer 12. One end of the spring 15 is fixedly connected to the outer shell 6. Moisture absorption holes 2 are opened on the outer wall of the first wrapping layer 1.

[0027] Specifically, when vibrations and noise occur during vehicle operation, the cushioning and sound insulation components inside the wrapping layer 1 come into play. The sound insulation cotton 13, in direct contact with the vehicle's interior, effectively absorbs interior noise and reduces sound transmission due to its porous structure. The sound insulation panel 8 further blocks the remaining noise from spreading outwards, enhancing the sound insulation effect. The cotton padding layer 9, thanks to its material properties, not only isolates some noise but also provides insulation, reducing heat loss from the vehicle interior. The silicone sheet 10, while resistant to high temperatures, also provides some cushioning against vibrations and noise. The rubber sheet 11 not only increases the overall strength of the pad, making it more durable, but also assists in cushioning during vehicle vibrations, converting vibration energy into heat and other forms of energy, reducing the transmission of vibrations into the vehicle interior, collectively creating a quiet and comfortable environment. The moisture-absorbing holes 2 on the outer wall of the wrapping layer 1 absorb moisture from the outside, keeping the inside of the pad dry and preventing moisture from affecting the performance of the components.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The disassembly assembly includes tooth 3, the inner wall of which is fixedly connected to the outer wall of wrapping layer 1; tooth 4 is fixedly connected to the outer wall of wrapping layer 12; zipper 5 is slidably connected to the outer wall of tooth 3; positioning groove 14 is provided on the inner wall of wrapping layer 12; positioning plate 7 is fixedly connected to the lower surface of wrapping layer 1; positioning plate 7 is slidably connected to the inner wall of positioning groove 14; positioning plate 7 is used to position wrapping layer 1 and moisture-absorbing hole 2 when connected; zipper 5 is slidably connected to the inner wall of tooth 4; zipper 5 is used to fix wrapping layer 1; zipper 5 is used to connect tooth 3 and tooth 4; cotton pad 9 is set on the inner wall of wrapping layer 1; cotton pad 9 is used for heat insulation and noise insulation; silicone plate 10 is set on the inner wall of wrapping layer 1; silicone plate 10 is used for high temperature resistance; rubber plate 11 is set on the inner wall of wrapping layer 1; rubber plate 11 is used to improve the strength of the pad and provide auxiliary cushioning.

[0029] Specifically, the disassembly process begins with the positioning plate 7 on the lower surface of the first layer 1 engaging with the positioning groove 14 on the inner wall of the second layer 12. The positioning plate 7 is slid into the positioning groove 14 to initially position the connection between the first layer 1 and the second layer 12, ensuring accurate alignment. The teeth 3 on the outer wall of the first layer 1 correspond to the teeth 4 on the outer wall of the second layer 12. The zipper 5 is slid along the outer wall of the teeth 3 until it connects with the inner wall of the teeth 4, thus connecting the teeth 3 and the teeth 4 and securing the first layer 1 and the second layer 12. When disassembly is required, the zipper 5 is reversed to disengage from the teeth 4, and the positioning plate 7 is then removed to separate the first layer 1 and the second layer 12, facilitating maintenance, replacement, or cleaning of the sound insulation pad.

[0030] Working Principle: When a car vibration damping and sound insulation pad is needed, the buffer and sound insulation components inside the wrapping layer 1 function when the car vibrates and generates noise during driving. The sound insulation panel 8 is in direct contact with the car's interior space, and its porous structure effectively absorbs interior noise and reduces sound transmission. The sound insulation cotton 13 further blocks the remaining noise from spreading outward, enhancing the sound insulation effect. The cotton pad layer 9, due to its material properties, can both isolate some noise and provide heat insulation, reducing heat loss from the car's interior. The silicone plate 10, while resistant to high temperatures, can also buffer vibration and noise to a certain extent. The rubber plate 11 not only improves the overall strength of the pad, making it more durable, but also assists in buffering vibrations, converting vibration energy into heat and other forms of energy, reducing the transmission of vibration into the car's interior. The moisture-absorbing holes 2 on the outer wall of the wrapping layer 1 can absorb moisture from the outside, keeping the inside of the pad dry. To prevent moisture from affecting the performance of each component, when subjected to a heavy impact, the first layer 1 drives the second layer 12 to compress the spring 15. At this time, the first layer 1 and the moisture-absorbing hole 2 slide inside the outer shell 6, and the spring 15 rebounds to achieve a secondary buffering effect. In addition, when installing the shock-absorbing and sound-insulating pad, the positioning plate 7 is slid into the positioning groove 14 to initially position the connection between the first layer 1 and the second layer 12, ensuring that the two are accurately aligned. The first tooth 3 corresponds to the second tooth 4. The zipper 5 slides along the first tooth 3 to connect the first tooth 3 and the second tooth 4, thus firmly fixing the first layer 1 and the second layer 12. When disassembly is required, the zipper 5 is reversed to disengage it from the second tooth 4. The first layer 1 is then opened, causing the positioning plate 7 to rotate and disengage from the positioning groove 14, thus separating the first layer 1 and the second layer 12. This facilitates maintenance, replacement, or cleaning of the inside of the sound-insulating pad.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
