For example, without departing from the scope of the various embodiments of this utility model, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0041] It should be noted that, in this utility model, unless otherwise explicitly specified and defined, terms such as "installation," "connection," and "fixation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] Please refer to Figures 1 to 4 This utility model provides a shock absorption device, including a first shock absorber 1 and a second shock absorber 2, wherein the first shock absorber 1 is provided with a first mounting component and a second mounting component.

[0043] Specifically, the first mounting assembly includes a first mounting base 3 and a first limiting member 4. The second shock absorber 2 and the first mounting base 3 are sleeved on the first shock absorber 1, and the two ends of the second shock absorber 2 respectively abut against the first position of the vehicle and the first mounting base 3. The first mounting base 3 is movable relative to the first shock absorber 1. The first limiting member 4 is disposed on the first shock absorber 1 to prevent the first mounting base 3 from moving relative to the first shock absorber 1.

[0044] The second mounting assembly includes a second mounting base 7 and a second limiting member 8. The second mounting base 7 is movably fitted onto the first shock absorber 1, and the second mounting base 7 is located on the side of the first mounting base 1 away from the second shock absorber 2. The second mounting base 7 is provided with an external connecting part 9 for connecting to a second position of the vehicle. The second limiting member 8 is provided on the first shock absorber 1 to prevent the second mounting base 7 from moving relative to the first shock absorber 1.

[0045] It should be noted that the first position of the vehicle is the vehicle body, and the second position of the vehicle is the vehicle suspension.

[0046] In this invention, since one end of the second shock absorber 2 abuts against the first mounting base 3, and the first mounting base 3 is movable, the second shock absorber 2 can move under the drive of the first mounting base 3, thereby allowing the overall axial length of the shock absorber to be flexibly adjusted. Furthermore, since the external connecting part 9 is disposed on the second mounting base 7, and the second mounting base 7 is movable, the external connecting part 9 can move under the drive of the second mounting base 7, allowing the distance between the external connecting part 9 and the second shock absorber 2 to be flexibly adjusted. This allows the external connecting part 9 and the second shock absorber 2 to adapt to vehicles of different sizes at different distances, and the space between the vehicle body and the suspension can be adjusted by adjusting the distance between the external connecting part 9 and the second shock absorber 2, providing good flexibility. In addition, this invention can also prevent the first mounting base 3 from moving relative to the first shock absorber 1 by the first limiting member 4, and prevent the second moving part 7 from moving relative to the first shock absorber 1 by the second limiting member 8, ensuring good stability after the first mounting base 3 and the second mounting base 7 are in place.

[0047] In one specific embodiment, the first mounting base 3 includes a hollow column 31 and a disc 32 formed by extending outward from the column 31. The second shock absorber 2 is sleeved on the first shock absorber 1 and the column 31, and the two ends of the second shock absorber 2 respectively abut against the first position of the vehicle and the disc 32.

[0048] Please combine Figure 3 and Figure 4 The distance h2 between the inner wall of the second damping member 2 and the outer wall of the first damping member 1 is between 4 mm and 7 mm, and the distance h1 between the inner wall of the second damping member 2 and the outer wall of the column 31 is between 0.8 mm and 1.2 mm.

[0049] Therefore, the shock absorption device provided by this utility model, based on the reasonable distance between the inner wall of the second shock absorber 2 and the outer wall of the first shock absorber 1, and the reasonable distance between the inner wall of the second shock absorber 2 and the outer wall of the column 31, has the advantages of compact structure and high stability. In addition, the structural design of the first mounting base 3, which includes a hollow column 31 and a disc 32 extending outward from the column 31, also effectively improves the installation stability of the second shock absorber 2, thereby improving the connection stability between the shock absorption device and the vehicle, and improving the shock absorption effect.

[0050] It should be noted that the inner wall of the second damper 2 is also the side of the second damper 2 closest to the first damper 1 and the column 31. In some cases, the second damper 2 may include... Figure 3 The spring shown is sleeved on the first damping member 1 and the column 31. The inner wall of the second damping member 2 is the side of the spring closest to the first damping member 1 and the column 31.

[0051] In one specific embodiment, please refer to Figure 3 The ratio of the outer diameter d1 of the disc 32 to the outer diameter d2 of the cylinder 31 can be between 1.4 and 1.7. For example, the outer diameter d1 of the disc 32 can be 90 mm and the outer diameter d2 of the cylinder 31 can be 60 mm, such that the ratio of the outer diameter d1 of the disc 32 to the outer diameter d2 of the cylinder 31 is 1.5.

[0052] Furthermore, the ratio of the outer diameter d3 of the second damper 2 to the outer diameter d1 of the disc 32 can be between 0.7 and 1.0. The outer diameter d3 of the second damper 2 is less than or equal to the outer diameter d1 of the disc 32, so that the projection of the second damper 2 on the disc 32 is located inside the disc 32, making the structure more compact and the stability of the second damper 2 better.

[0053] In one specific embodiment, please refer to Figure 1 The second damping element 2 can be helical. Specifically, the second damping element 2 can be a helical spring, and preferably, the diameter of the helical spring remains constant along its length. Therefore, compared to a conical spring with a varying diameter, the helical spring structure provided in this embodiment is more compact and has higher stability.

[0054] In one specific embodiment, please refer to Figure 1 and Figure 2 The first damping component 1 is provided with an external thread 5, and the first limiting component 4 is sleeved on the first damping component 1. Both the inner wall of the first mounting base 3 and the inner wall of the first limiting component 4 are provided with internal threads 6. The internal thread 6 on the inner wall of the first mounting base 3 engages with the external thread 5 to allow the first mounting base 3 to move relative to the first damping component 1. The internal thread 6 on the inner wall of the first limiting component 4 engages with the external thread 5 to prevent the first mounting base 3 from moving relative to the first damping component 1.

[0055] For example, in an embodiment where the first mounting base 3 includes a column 31 and a disc 32, the internal thread 6 on the inner wall of the first mounting base 3 can be provided on the inner wall of the column 31. The first mounting base 3 can move relative to the first shock absorber 1 by engaging the internal thread 6 with the external thread 5 on the inner wall of the column 31. After moving to the expected position, the first limiting member 4 can also move relative to the first shock absorber 1 by engaging the internal thread 6 with the external thread 5 on its inner wall to approach the first mounting base 3. The first limiting member 4 prevents the first mounting base 3 from moving by abutting the side of the first mounting base 3 away from the second shock absorber 2.

[0056] For example, please refer to Figure 2The external thread 5 can be distributed along the axial direction of the first damping member 1, and the length of the external thread 5 can be between 12cm and 18cm. The internal thread 6 on the inner wall of the column 31 and the internal thread 6 on the inner wall of the first limiting member 4 can also be distributed along the axial direction of the first damping member 1. Optionally, the length of the internal thread 6 on the inner wall of the column 31 can be between 1.2cm and 2cm, and the length of the internal thread 6 on the inner wall of the first limiting member 4 can be between 0.6mm and 1mm. In actual use, the length of the thread can be adaptively set according to the adjustment range requirements.

[0057] Furthermore, this embodiment can be configured based on the previous embodiment. Specifically, the second mounting base 7 and the second limiting member 8 are both sleeved on the first shock absorber 1, and the inner walls of both the second mounting base 7 and the second limiting member 8 are provided with internal threads 6. The internal threads 6 on the inner wall of the second mounting base 7 cooperate with the external threads 5, so that the second mounting base 7 can move relative to the first shock absorber 1. The internal threads 6 on the inner wall of the second limiting member 8 cooperate with the external threads 5 to prevent the second mounting base 7 from moving relative to the first shock absorber 1. Specifically, the second limiting member 8 moves closer to the second mounting base 7 by moving relative to the first shock absorber 1, and the second limiting member 8 prevents the movement of the second mounting base 7 by abutting the side of the second mounting base 7 away from the first mounting base 3.

[0058] Optionally, the length of the internal thread 6 of the second mounting base 7 and the length of the internal thread 6 of the second limiting member 8 can also be adapted to actual needs, and no specific limitation is made here.

[0059] In one specific embodiment, please refer to Figure 1 and Figure 2 The outer periphery of the end of the column 31 extends radially outward along the first shock absorber 1 to form a disc 32. Thus, in this embodiment, the disc 32 is flat, with no bent parts on the edges or surface, making it less prone to water accumulation, easier to process and manufacture, lower in cost, and more economical.

[0060] In one specific embodiment, the first damping component 1 includes a damper, which may specifically include an oil reservoir, a working cylinder, and a piston rod.

[0061] The working cylinder is located inside and connected to the oil reservoir. One end of the piston rod extends into the working cylinder, while the other end protrudes to the outside. The first damping component 1 in the figure can be understood as the oil reservoir of the shock absorber. The working cylinder, piston rod, and other components are not shown in the figure.

[0062] In summary, the shock absorber provided by this utility model can move the second shock absorber through the first mounting base and move the external connecting part through the second mounting base, so that the overall axial length of the shock absorber and the distance between the external connecting part and the second shock absorber can be flexibly adjusted. The shock absorber can be adapted to vehicles of different sizes, and the space between the vehicle body and the suspension can be adjusted by adjusting the distance between the external connecting part and the second shock absorber, thus exhibiting good flexibility and adaptability.

[0063] Furthermore, this utility model achieves a compact structure and high stability based on the reasonable distance and proportion settings between the various components. The reasonable structural design of the first mounting base effectively improves the installation stability of the second shock absorber, thereby enhancing the connection stability between the shock absorber and the vehicle during actual use and improving the shock absorption effect.

[0064] Furthermore, the disc body of this utility model can be formed by extending the end of the column outward along the radial direction of the first shock absorber. The disc body is flat and has no bent parts on the edges and surface, so it is not easy to accumulate water and is easy to process and manufacture, with lower cost and better economy.
