Description

Technical Field

[0001] This utility model relates to the technical field of automotive rubber shock absorber sleeves, specifically to an adjustable high-performance automotive rubber shock absorber sleeve. Background Technology

[0002] Rubber vibration damping sleeves are widely used vibration damping components in various machinery, equipment, and vehicles. They typically consist of a rubber body and metal fittings. The rubber body is generally cylindrical or rectangular in shape, with a hollow or solid internal structure. Its exterior and interior may feature special textures or raised designs to enhance vibration damping and friction. The metal fittings, such as bolts and nuts, are used for connection to the mounting points. Utilizing the high elasticity and viscoelasticity of rubber, when equipment or components vibrate, the rubber vibration damping sleeve absorbs and dissipates vibration energy, converting mechanical energy into heat or other forms of energy, thereby reducing the amplitude and transmission of vibration and achieving the purpose of vibration reduction and noise reduction.

[0003] During vehicle operation, various vibrations are generated due to uneven road surfaces, engine operation, and vehicle acceleration and deceleration. These vibrations can affect the ride comfort of passengers and damage vehicle components. Traditional automotive rubber shock absorber bushings generally use fixed structure and material parameters, resulting in relatively limited shock absorption performance. They cannot meet diverse shock absorption needs under different road conditions. For example, when driving on highways, shock absorber bushings need to effectively filter out minor road vibrations to provide a smooth and comfortable driving experience; while in off-road conditions, shock absorber bushings are required to have stronger buffering capacity to cope with larger impacts. Therefore, an adjustable high-performance automotive rubber shock absorber bushing is proposed. Utility Model Content

[0004] This invention provides an adjustable high-performance automotive rubber shock absorber to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An adjustable high-performance automotive rubber shock absorber includes an automotive rubber shock absorber sleeve. The internal part of the automotive rubber shock absorber sleeve has a shock absorption enhancement mechanism. A pressurization mechanism is located at the bottom of the shock absorption enhancement mechanism. The shock absorption enhancement mechanism includes a shock absorber cylinder. A pressure sensor is located in the middle of the bottom of the shock absorber cylinder's inner cavity. A first solenoid valve is located on one side of the bottom of the shock absorber cylinder's inner cavity, and a second solenoid valve is located on the other side of the bottom of the shock absorber cylinder's inner cavity. A separating piston is located inside the shock absorber cylinder, above the separating piston and inside the shock absorber cylinder. A compression piston has flow holes on its surface.

[0007] A further improvement of this utility model is that: a pressing component is fixedly connected to the top of the compression piston, and a sealing ring is sleeved on the surface of the pressing component.

[0008] A further improvement of this utility model is that: the surface of the sealing ring is fixedly connected to the inner wall of the shock-absorbing cylinder, a spring is fixedly connected to the surface of the extrusion piece, and the lower end of the spring is fixedly connected to the surface of the shock-absorbing cylinder.

[0009] A further improvement of the present invention is that the vehicle rubber shock absorber includes a lower shock absorber and an upper shock absorber, and the structure of the lower shock absorber is the same as that of the upper shock absorber.

[0010] A further improvement of the present invention is that the lower shock absorber sleeve includes a sleeve body, the sleeve body has an air cavity inside, and the sleeve body has a groove on its surface.

[0011] A further improvement of the present invention is that the pressurization mechanism includes a high-pressure gas cylinder, and a connecting pipe is provided at the upper end of the high-pressure gas cylinder.

[0012] A further improvement of this utility model is that a third solenoid valve is provided at one end of the connecting pipe near the high-pressure gas cylinder, and one end of the connecting pipe is connected to the first solenoid valve.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] This invention provides an adjustable high-performance automotive rubber shock absorber sleeve. Through the inclusion of a shock-absorbing reinforcement mechanism, when vibration occurs, the spring is compressed by an extruder, buffering and storing the kinetic energy generated by the vibration. Simultaneously, the compression piston presses the hydraulic oil above the separating piston, causing it to flow along the flow hole to the top of the extrusion piston. Due to the size limitation of the flow hole, a large resistance is applied to the extruder, thereby consuming the kinetic energy stored in the spring and enhancing the shock-absorbing performance of the rubber sleeve. Furthermore, when the hydraulic oil is compressed, it also pushes the separating piston downwards, compressing the high-pressure air in the cavity below the separating piston, further improving the shock absorption effect. The air pressure in the cavity below the separating piston can be adjusted via a high-pressure gas cylinder, thereby changing the overall shock absorption effect of the rubber shock absorber sleeve and making it easier to use.

[0020] The present invention will be further described in detail below with reference to embodiments: Example 1

[0021] like Figure 1-4 As shown, this utility model provides an adjustable high-performance automotive rubber shock absorber, including an automotive rubber shock absorber. The shock absorber has an internal shock absorption enhancement mechanism, and a pressure boosting mechanism is located at the bottom of the shock absorption enhancement mechanism. The shock absorption enhancement mechanism includes a shock absorber cylinder 21. A pressure sensor 22 is located in the middle of the bottom of the inner cavity of the shock absorber cylinder 21. A first solenoid valve 23 is located on one side of the bottom of the inner cavity of the shock absorber cylinder 21, and a second solenoid valve 24 is located on the other side of the bottom of the inner cavity of the shock absorber cylinder 21. A separating piston 25 is located inside the shock absorber cylinder 21. A compression piston 26 is located above the separating piston 25 and inside the shock absorber cylinder 21. A flow hole 27 is located on the surface of the compression piston 26. An extrusion member 28 is fixedly connected to the top of the compression piston 26. A sealing ring 29 is fitted onto the surface of the extrusion member 28. The surface of the sealing ring 29 is fixedly connected to the inner wall of the shock absorber cylinder 21. A spring 210 is fixedly connected to the surface of the extrusion member 28, and the lower end of the spring 210 is fixedly connected to the surface of the shock absorber cylinder 21.

[0022] In this embodiment, the upper damping sleeve 12 compresses the extrusion member 28 downward, causing the spring 210 to contract under force and store the kinetic energy generated by vibration. The extrusion member 28 pushes the compression piston 26 downward, compressing the hydraulic oil above the separating piston 25, so that the hydraulic oil flows into the upper part of the compression piston 26 along the flow hole 27. Due to the influence of the hydraulic oil flow resistance, the buffering effect of the damping sleeve can be improved again. When the spring 210 and the automotive rubber damping sleeve rebound, the compression piston 26 moves upward, causing the hydraulic oil to return to the upper part of the separating piston 25 again. The kinetic energy is consumed by the hydraulic oil flow resistance, improving the damping effect. When the hydraulic oil is squeezed, the hydraulic oil pressure above the separating piston 25 increases. When it is greater than the air pressure below the separating piston 25, the air pressure below the separating piston 25 is compressed, thereby improving the overall damping effect of the damping sleeve again. Example 2

[0023] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the vehicle rubber shock absorber includes a lower shock absorber 11 and an upper shock absorber 12. The structure of the lower shock absorber 11 is the same as that of the upper shock absorber 12. The lower shock absorber 11 includes a sleeve body 111. An air chamber 112 is provided inside the sleeve body 111, and a groove 113 is provided on the surface of the sleeve body 111.

[0024] In this embodiment, the kinetic energy generated by the vehicle vibration during use causes the upper shock absorber 12 to move downward and compress the lower shock absorber 11. When the rubber expands and contracts, it absorbs and dissipates vibration energy, converting mechanical energy into other forms of energy such as heat energy, thereby reducing the amplitude and transmission of vibration. Example 3

[0025] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the pressurization mechanism includes a high-pressure gas cylinder 31, a connecting pipe 32 is provided at the upper end of the high-pressure gas cylinder 31, a third solenoid valve 33 is provided at one end of the connecting pipe 32 near the high-pressure gas cylinder 31, and one end of the connecting pipe 32 is connected to the first solenoid valve 23.

[0026] In this embodiment, when it is necessary to improve the shock absorption sensitivity of the shock-absorbing sleeve, the second solenoid valve 24 is opened, and the air pressure sensor 22 detects the air pressure. The gas below the separating piston 25 is discharged to reduce the air pressure, which makes the separating piston 25 easier to move down and improves the shock absorption sensitivity. Conversely, the first solenoid valve 23 and the third solenoid valve 33 are opened, and the air pressure is increased through the high-pressure gas cylinder 31, which improves the rigidity of the shock-absorbing sleeve and allows for flexible adjustment of the shock absorption effect, making it easier to use.

[0027] The working principle of this adjustable high-performance automotive rubber shock absorber will be explained in detail below.

[0028] like Figure 1-4As shown, during use, the kinetic energy generated by vehicle vibration causes the upper shock absorber 12 to move downwards, compressing the lower shock absorber 11. During the expansion and contraction of the rubber, the vibration energy is absorbed and dissipated, converting mechanical energy into heat and other forms of energy, thereby reducing the amplitude and transmission of vibration. Simultaneously, the upper shock absorber 12 compresses the extruder 28 downwards, causing the spring 210 to contract and store the kinetic energy generated by the vibration. The extruder 28 pushes the compression piston 26 downwards, compressing the hydraulic oil above the separator piston 25. This allows the hydraulic oil to flow along the flow hole 27 above the compression piston 26. Due to the resistance of the hydraulic oil flow, the damping effect of the shock absorber 26 is further enhanced. When the spring 210 and the vehicle rubber shock absorber 21 rebound, the compression piston 26 moves upwards, causing the hydraulic oil to return to the separator piston 25. Above the separator piston 25, the kinetic energy is consumed by the resistance of hydraulic oil flow, thus improving the damping effect. When the hydraulic oil is squeezed, the hydraulic oil pressure above the separator piston 25 increases. When it exceeds the air pressure below the separator piston 25, it compresses the air pressure below the separator piston 25, thereby further improving the overall damping effect of the damping sleeve. When it is necessary to increase the damping sensitivity of the damping sleeve, the second solenoid valve 24 is opened, and the air pressure sensor 22 detects the air pressure. Part of the gas below the separator piston 25 is discharged, reducing the air pressure, which makes it easier for the separator piston 25 to move down and increases the damping sensitivity. Conversely, the first solenoid valve 23 and the third solenoid valve 33 are opened, and the air pressure is increased through the high-pressure gas cylinder 31, which increases the rigidity of the damping sleeve. The damping effect can be flexibly adjusted, making it easier to use.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
