[0002] In related technologies, in the vehicle suspension system, the shock absorber assembly serves as the main buffer component to dampen the vehicle's vibrations. When the shock absorber assembly is working, the piston rod reciprocates, continuously pressurizing the hydraulic oil.

[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0036] The following is for reference. Figures 1-5A vibration damper assembly 200 according to an embodiment of the present invention is described.

[0037] like Figures 1-5 As shown, the shock absorber assembly 200 according to an embodiment of the present invention includes: a shock absorber 10, an anti-slip sleeve 20, and a movable member 22.

[0038] An installation space 21 is formed inside the anti-slip sleeve 20. The shock absorber 10 is slidably installed in the installation space 21. The anti-slip sleeve 20 is provided with a vent 23. One end of the vent 23 is open towards the installation space 21 and the other end is open towards the outside of the anti-slip sleeve 20. The movable part 22 is movably installed in the installation space 21 and is adapted to move synchronously with the shock absorber 10. There are two sets of vent 23. The two sets of vent 23 are distributed at intervals along the axial direction of the anti-slip sleeve 20. In the axial direction of the anti-slip sleeve 20, the movable part 22 is located between the two sets of vent 23 to divide the installation space 21 into an air inlet space and an air outlet space.

[0039] Therefore, after the shock absorber 10 is installed inside the anti-slip sleeve 20, the anti-slip sleeve 20 can provide a certain degree of protection for the shock absorber 10, that is, the shock absorber 10 will not be contaminated by external debris when it is working. At the same time, the vent holes 23 provided on the anti-slip sleeve 20 are spaced apart in its axial direction. Thus, the two sets of vent holes 23 are located at both ends of the anti-slip sleeve 20, so that when the moving part 22 moves synchronously with the shock absorber 10, the moving part 22 can drive the air in the installation space 21 to flow and exchange with the outside air through the two sets of vent holes 23. In this way, the air in the installation space 21 can dissipate heat from the shock absorber 10 when it flows, which can extend the service life of the shock absorber 10.

[0040] For example, after the anti-slip sleeve 20 forms the installation space 21, the shock absorber 10 can be slidably installed in the installation space 21. In this way, the anti-slip sleeve 20 can protect the shock absorber 10. That is, when the vehicle 1000 passes through a section of road with standing water, the water splashed up by the wheels can be blocked by the anti-slip sleeve 20, so that external dirt will not adhere to the shock absorber 10 when it is working, and thus will not affect the use of the shock absorber 10.

[0041] The movable component 22 is located between two sets of vents 23 and divides the installation space 21 into an air intake space and an air exhaust space. When the movable component 22 moves synchronously with the shock absorber 10, it can change the size of the air intake space and the air exhaust space, so that air in the air intake space and the air exhaust space can enter the air intake space or leave the air exhaust space through the vents 23. As the movable component 22 moves continuously, the air intake space and the air exhaust space also have air intake and exhaust situations. In this way, the air in the installation space 21 can always exchange with the outside air, so that the movable component 22 can dissipate heat from the shock absorber 10 and extend the service life of the shock absorber 10 when it moves.

[0042] According to the embodiment of the present invention, the shock absorber assembly 200 includes a shock absorber 10 installed in the mounting space 21 of the anti-slip sleeve 20. The anti-slip sleeve 20 protects the shock absorber 10 from external influences. At the same time, a movable part 22 is provided in the mounting space 21 to move with the shock absorber 10, thereby allowing the air in the mounting space 21 to exchange with the outside, which can dissipate heat from the shock absorber 10 and improve the service life of the shock absorber 10.

[0043] In some embodiments, such as Figures 3-5 As shown, the anti-slip sleeve 20 includes an inner sidewall 24 and an outer sidewall 25, which are distributed radially apart along the anti-slip sleeve 20.

[0044] Therefore, the inner wall 24 and the outer wall 25 are spaced apart, so there is a certain gap between the inner wall 24 and the outer wall 25 of the anti-slip sleeve 20. This allows the movable part 22 to be positioned between the inner wall 24 and the outer wall 25, making it easier for the movable part 22 to drive the air in the installation space 21 to exchange with the outside air. This ensures that the air flow direction in the installation space 21 is consistent, which improves the heat exchange effect of the movable part 22 and thus improves the heat dissipation effect of the vibration damper 10, thereby extending the service life of the vibration damper 10.

[0045] In some embodiments, such as Figures 3-5 As shown, the vent 23 includes an inner through hole 231 and an outer through hole 232. The inner through hole 231 is disposed on the inner side wall 24, and the outer through hole 232 is disposed on the outer side wall 25. The inner through hole 231 and the outer through hole 232 are disposed opposite to each other.

[0046] Therefore, the relative arrangement of the inner through hole 231 and the outer through hole 232 results in a shorter airflow path through the inner through hole 231 and the outer through hole 232. This allows the air inside the anti-slip sleeve 20 to pass through more quickly when exchanging with the outside, thus making the air exchange between the installation space 21 and the outside air more efficient. This allows the shock absorber 10 to cool down more quickly when exchanging heat through the moving part 22, thereby increasing the service life of the shock absorber 10.

[0047] For example, after the shock absorber 10 has been working for a long time, the hydraulic oil inside the shock absorber 10 will heat up and heat the air inside the anti-slip sleeve 20. At this time, the moving part 22 will move synchronously with the shock absorber 10. In this way, the air inside the anti-slip sleeve 20 will exchange heat with the air outside the anti-slip sleeve 20 through the vent 23 driven by the moving part 22, thereby cooling down the shock absorber 10 and extending the service life of the shock absorber 10.

[0048] In some embodiments, such as Figures 3-5As shown, at least one of the inner through hole 231 and the outer through hole 232 is provided with a filter device 233.

[0049] Therefore, the filter device 233 can filter the air entering the anti-slip sleeve 20, so that some dust will not enter the anti-slip sleeve 20, thereby protecting the shock absorber 10 inside the anti-slip sleeve 20 and extending the service life of the shock absorber 10.

[0050] For example Figure 3 As shown, the filter device 233 is constructed as a filter screen and the filter screen is located at the external through hole 232. In this way, when the air in the installation space 21 exchanges with the outside air, the filter screen can remove some of the impurities attached to the air, so that the air entering the installation space 21 will not affect the normal operation of the shock absorber 10.

[0051] A filter device 233 can be installed at the inner through hole 231, or at the outer through hole 232, or at both the inner through hole 231 and the outer through hole 232. This will make the air entering the installation space 21 cleaner and will not affect the use of the shock absorber 10.

[0052] In some embodiments, the damper assembly 200 further includes a folding sleeve 30 connected to an anti-slip sleeve 20. The damper 10 includes a damper body 11 and an elastic element 12. The damper body 11 is connected to the elastic element 12. The anti-slip sleeve 20 is sleeved on the damper body 11, and the folding sleeve 30 is sleeved on the elastic element 12.

[0053] Therefore, the folding sleeve 30 is fitted onto the elastic element 12 to protect the elastic element 12. That is, the folding sleeve 30 can block the water splashed by the wheel, thus preventing the elastic element 12 from being corroded by the water. At the same time, when the shock absorber 10 is working, the elastic element 12 will extend and retract, and the folding sleeve 30 will also move with the elastic element 12. In this way, no matter what state the elastic element 12 is in, the folding sleeve 30 can protect the elastic element 12, so that the shock absorber 10 will not be affected by the external environment and thus ensure the service life of the shock absorber 10.

[0054] For example, the elastic element 12 can be constructed as a spring, which makes it more convenient to place the spring in the mounting space 21, while also providing good vibration damping performance.

[0055] In some embodiments, such as Figures 3-5 As shown, the damper assembly 200 also includes a spacer 26, which is located between the mounting space 21 and the elastic member 12 in the axial direction of the damper 10.

[0056] Therefore, the spacer 26 can act as a separator between the installation space 21 and the elastic element 12, so that the hot air in the installation space 21 is not easy to enter the elastic element 12. This can prevent the heat in the installation space 21 from affecting the elastic element 12 and thus affecting the performance of the elastic element 12 itself.

[0057] In some embodiments, such as Figures 3-5 As shown, the shock absorber 10 also includes a support 13, which is connected to the elastic member 12, and a fixed rod 27 is connected between the support 13 and the movable member 22.

[0058] Therefore, after the support 13 is connected to the elastic element 12, the support 13 will also move along with the elastic element 12 when the elastic element 12 extends or retracts. The support 13 is also connected to the movable element 22 through the fixed rod 27. In this way, the support 13 can drive the movable element 22 when it moves with the elastic element 12, thereby realizing the synchronous movement of the movable element 22 and the shock absorber 10. At the same time, the movable element 22 can drive the air flow in the installation space 21 and exchange with the outside air through the vent 23, thereby heat exchange for the shock absorber 10 and extending the service life of the shock absorber 10.

[0059] In some embodiments, such as Figures 3-5 As shown, the fixing rod 27 passes through the spacer 26 and slides with the spacer 26.

[0060] Therefore, when the fixed rod 27 is connected to the movable part 22, it passes through the spacer 26. At the same time, the fixed rod 27 will slide with the spacer 26. In this way, when the fixed rod 27 drives the movable part 22 to move, it will not be affected by the spacer 26. That is, when the fixed rod 27 drives the movable part 22 to move, the spacer 26 can ensure that the air in the installation space 21 is not easy to enter the elastic element 12. Thus, the air in the installation space 21 of the shock absorber 10 will not affect the elastic element 12 while exchanging heat with the outside.

[0061] In other embodiments, the fixing rod 27 does not pass through the spacer 26, which is located inside the fixing rod 27. In this way, when the fixing rod 27 moves with the support 13 and drives the movable part 22, the spacer 26 can also separate the installation space 21 and the elastic part 12.

[0062] The present invention also proposes a suspension system 100.

[0063] like Figures 1-2 As shown, the suspension system 100 according to an embodiment of the present invention includes: a cantilever 101, a connecting arm 102, and a shock absorber assembly 200 of any of the above embodiments, wherein the shock absorber assembly 200 is connected between the cantilever 101 and the connecting arm 102.

[0064] Thus, the shock absorber assembly 200 connects the cantilever 101 and the connecting arm 102. The cantilever 101 is connected to the chassis of the vehicle 1000, and the connecting arm 102 is connected to the wheel. In this way, when the vehicle 1000 passes over uneven road surfaces, the shock absorber assembly 200 can alleviate the impact on the wheel, so that the occupants of the vehicle 1000 are less likely to feel the bumps. At the same time, the shock absorber assembly 200 is equipped with an anti-slip sleeve 20, and the anti-slip sleeve 20 is also connected to a folding sleeve 30. This ensures that the water splashed out by the wheel will not come into contact with the shock absorber 10, so that the shock absorber 10 is not easily affected by the external environment. In addition, when the shock absorber 10 is working, the moving part 22 drives the air in the mounting space 21 to exchange with the outside, thereby dissipating heat from the shock absorber 10 and extending the service life of the shock absorber 10.

[0065] The present invention also proposes a vehicle 1000.

[0066] like Figure 6 As shown, the vehicle 1000 according to an embodiment of the present invention includes the suspension system 100 of the above embodiment.

[0067] According to an embodiment of the present invention, in the suspension system 100 of the vehicle 100, the shock absorber 10 is installed in the mounting space 21 of the anti-slip sleeve 20. In this way, the anti-slip sleeve 20 can protect the shock absorber 10 from external influences. At the same time, a movable part 22 is provided in the mounting space 21, which can move with the shock absorber 10 to allow the air in the mounting space 21 to exchange with the outside, thereby dissipating heat from the shock absorber 10 and improving the service life of the shock absorber 10.
