[0003] Most existing rubber pads use a single rubber material, relying on their elasticity to buffer vibrations. However, under long-term use, facing the high-frequency vibrations of a vehicle, they are prone to plastic deformation, reducing their elasticity and thus affecting their shock absorption effect and service life. Furthermore, a single rubber material is not effective in preventing the intrusion of oil, gas, and dust. Therefore, we provide a combination rubber pad for automobiles. Utility Model Content

[0007] Preferably, the inner side of the collar is provided with sealing grooves at the upper and lower ends, and the outer walls of the bottom rubber pad and the surface rubber pad are fitted with sealing rings that are compatible with the sealing grooves.

[0008] Preferably, the bottom rubber pad, the middle rubber pad, and the top rubber pad are bonded together by a vulcanization process, and the middle rubber pad is distributed between the bottom rubber pad and the top rubber pad.

[0009] Preferably, the bottom end of the bottom pad is serrated, and the bottom pad is made of nitrile rubber.

[0010] Preferably, the middle layer pad is made of silicone rubber, the surface layer pad is made of fluororubber, and the interior of the surface layer pad is honeycomb-shaped.

[0011] Preferably, the top of the energy-absorbing rod and the top of the collar are on the same horizontal plane, and the energy-absorbing rod is made of sponge material.

[0012] By employing the above technical solution, this utility model provides a rubber combination pad for automobiles, which has at least the following beneficial effects:

[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] Example 1

[0026] Existing technologies using a single rubber material for shock absorption often suffer from reduced shock absorption and cushioning performance after prolonged use. This embodiment provides a composite rubber pad for automobiles that improves the overall shock absorption performance of the device through a multi-layered composite structure and modular design. Furthermore, it effectively prevents the intrusion of oil, gas, and dust, thus enhancing the assembly and sealing performance of the device. Please refer to... Figure 1 - Figure 5 The rubber assembly pad for automobiles includes a collar 1. Two symmetrically distributed positioning sleeves are installed on the lower outer wall of the collar 1, enabling rapid positioning of the entire device, reducing manual positioning time, and improving installation efficiency. The collar 1 contains a multi-layered shock-absorbing and sealing mechanism 2 to reduce pressure. The shock-absorbing and sealing mechanism 2, through its multi-layered composite structure and modular design, enhances the shock absorption effect, counteracts the impact force generated by high-frequency vibrations, and thus extends the service life of the entire device.

[0027] Most existing rubber pads use a single rubber material, relying on their elasticity to buffer vibrations. However, under long-term use, facing the high-frequency vibrations of a vehicle, they are prone to plastic deformation, reducing their elasticity and thus affecting their shock absorption effect and service life. Furthermore, a single rubber material is not effective at preventing the intrusion of oil, gas, and dust. To address these issues, the shock absorption sealing mechanism 2 includes a bottom rubber pad 21 installed inside the sleeve 1. The bottom rubber pad 21, the middle rubber pad 23, and the surface rubber pad 26 are tightly bonded together through a vulcanization process. This vulcanization process ensures a tight bond between the three layers, preventing delamination and extending the service life of the combined pads. The bottom of the bottom rubber pad 21 has a serrated bottom to enhance friction with metal parts and prevent sliding displacement. The bottom rubber pad 21 is made of nitrile rubber, whose oil and wear resistance effectively copes with oil and wear encountered during vehicle use. To enhance the stability and durability of the composite pad, the bottom rubber pad 21 has multiple sets of cushioning protrusions 22 installed at its top, and a middle rubber pad 23 is installed at its top. The middle rubber pad 23 is made of silicone rubber, utilizing its high elasticity and cushioning performance, combined with the internal cushioning spring 25 and ball groove 24 structure, to effectively absorb vibration energy and improve the overall shock absorption effect. The middle rubber pad 23 is distributed between the bottom rubber pad 21 and the top rubber pad 26, and the bottom of the middle rubber pad 23 has multiple sets of ball grooves 24 corresponding to the positions of the cushioning protrusions 22. Multiple sets of buffer springs 25 are connected inside the middle layer rubber pad 23 and above the ball groove 24. A surface rubber pad 26 is installed on the top of the middle layer rubber pad 23. The surface rubber pad 26 is made of fluororubber, which has strong resistance to high and low temperatures and corrosion. Its internal honeycomb structure and sponge energy-absorbing rods 27 form a dual energy-absorbing system, which can offset the impact force generated by high-frequency vibration. The honeycomb structure inside the surface rubber pad 26 can also enhance the shock absorption and buffering capacity, and improve the shock absorption performance of the device. Multiple sets of energy-absorbing rods 27 are installed on the top of the surface rubber pad 26 in an array. The top of the energy-absorbing rod 27 is at the same level as the top of the collar 1, ensuring that the energy-absorbing rod 27 can directly contact the vibration source, thereby initially absorbing the energy generated by the vibration. The energy-absorbing rod 27 is made of sponge material, which has good elasticity and strong energy absorption, and can effectively absorb high-frequency vibration energy. Together with the surface fluororubber honeycomb structure, it forms a dual shock absorption system, which enhances the shock absorption effect of the device. The inner side of the collar 1 has sealing grooves 28 at the upper and lower ends. The bottom rubber pad 21 and the outer wall of the surface rubber pad 26 are fitted with sealing rings 29 that are compatible with the sealing grooves 28.The inner ring 1 is composed of a bottom rubber pad 21, a middle rubber pad 23, and a top rubber pad 26 arranged sequentially from bottom to top. These three layers are tightly bonded together through a vulcanization process. The bottom rubber pad 21 has a serrated bottom end and is made of nitrile rubber. Its top cushioning protrusion 22 is embedded in the corresponding ball groove 24 at the bottom end of the middle rubber pad 23, providing a certain cushioning and shock absorption effect. The middle rubber pad 23 is made of silicone rubber and is located above the ball groove 24, connected to a cushioning spring 25. The deformation of the cushioning spring 25, in conjunction with the ball groove 24 and the cushioning protrusion 22, absorbs shock. To absorb vibration energy and improve shock absorption, the surface rubber pad 26 is made of fluororubber and has a honeycomb structure inside. The array of sponge energy-absorbing rods 27 and the honeycomb structure of the surface rubber pad 26 form a dual energy absorption system to offset the impact of high-frequency vibration. At the same time, when the bottom rubber pad 21 and the surface rubber pad 26 are assembled inside the collar 1, the sealing ring 29 can be inserted into the sealing groove 28 under pressure to form a double sealing barrier to prevent the intrusion of oil, gas and dust, which has certain practical performance.
