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] Currently, vehicles use shock absorbers and elastic components to provide cushioning, but the existing connection methods between these components limit their application in vehicles, resulting in limited functionality and an inability to meet diverse user needs. Furthermore, current methods of adjusting vehicle height by manually replacing springs, shock absorbers, or tires are difficult, time-consuming, and labor-intensive.

[0043] Based on this, refer to Figures 1 to 4 This utility model provides a shock absorber, including a shock absorber body, an elastic element 1, a first moving element 2, and a second moving element 3.

[0044] Specifically, the shock absorber body includes an outer cylinder 4, and the first movable member 2 and the second movable member 3 are movably mounted on the outer cylinder 4. An elastic member 1 is wound around the outer cylinder 4, with one end of the elastic member 1 abutting against the first movable member 2 and the other end abutting against the vehicle body (not shown in the figure).

[0045] The outer wall of the outer cylinder 4 is provided with a first connecting structure, the first moving part 2 is provided with a second connecting structure, and the second moving part 3 is provided with a third connecting structure. The first moving part 2 cooperates with the first connecting structure through the second connecting structure to achieve initial positioning of the first moving part 2. The second moving part 3 is located on the side of the first moving part 2 away from the elastic member 1, and the second moving part 3 cooperates with the first connecting structure through the third connecting structure to achieve complete positioning of the first moving part 2.

[0046] Understandably, in actual use, the end of the outer cylinder 4 furthest from the elastic element 1 can be connected to the vehicle's suspension via a connecting component (not shown), while the end of the elastic element 1 furthest from the vehicle's suspension abuts against the vehicle's body. Therefore, the vehicle's ground clearance is affected by the overall length of the shock absorber.

[0047] In this invention, the movement of the first moving member 2 drives the elastic member 1 to move on the outer cylinder 4, thereby adjusting the overall length of the shock absorber. This allows the invention to not only provide shock absorption but also adjust the vehicle's ground clearance, meeting diverse user needs and solving the problem of limited functionality in existing shock absorbers. It offers excellent flexibility and a superior user experience. Furthermore, after the first moving member 2 is in place, it is initially positioned by the first connecting structure and then fully positioned by the second moving member 3. This prevents the first moving member 2 from moving due to external forces, ensuring its stability and providing good support for the elastic member 1. This guarantees stable cooperation between the shock absorber and the elastic member, improving cushioning performance.

[0048] In one specific embodiment, please refer to Figure 3 The first connecting structure may include a plurality of snap-fit ​​parts 9 that are radially retractable along the outer cylinder 4, and the plurality of snap-fit ​​parts 9 are spaced apart along the axial direction of the outer cylinder 4 on the outer wall of the outer cylinder 4. The second connecting structure includes a first positioning hole 10, and the third connecting structure includes a second positioning hole 13.

[0049] The first moving part 2 engages with the locking part 9 through the first positioning hole 10 to achieve initial positioning of the first moving part 2. The second moving part 3 engages with the locking part 9 through the second positioning hole 13 to achieve complete positioning of the first moving part 2.

[0050] Specifically, in use, the first moving part 2 can be engaged with different engaging parts 9 through the first positioning hole 10, thereby positioning it at different positions on the outer cylinder 4. The engaging parts 9, by engaging with the first positioning hole 10 of the first moving part 2, provide support for the first moving part 2, thus defining its position and providing good stability, achieving initial positioning of the first moving part 2. Similarly, the second moving part 3 can be engaged with different engaging parts 9 through the second positioning hole 13, thereby positioning it at different positions on the outer cylinder 4. Specifically, the second moving part 3, through the second positioning hole 13, engages with the engaging part 9, approaching the side of the first moving part 2 away from the elastic member 1, thereby completely positioning the first moving part 2 by abutting against it, further improving the stability of the first moving part 2.

[0051] In one specific embodiment, please refer to Figure 5The bottom of the snap-fit ​​part 9 is embedded in the outer wall of the outer cylinder 4, and the bottom of the snap-fit ​​part 9 is connected to the outer cylinder 4 through the elastic reset member 12, thereby achieving retractability.

[0052] Furthermore, the outer diameter of the snap-fit ​​part 9 can be gradually reduced from the side closer to the outer cylinder 4 to the side farther away from the outer cylinder 4, thereby reducing the impact of the snap-fit ​​part 9 on the movement of the first moving member 2 and the second moving member 3, resulting in a better user experience.

[0053] In one specific embodiment, the first connecting structure may include an external thread 5. The first moving member 2 has a hollow structure, and the second connecting structure is located on the inner surface of the first moving member 2, wherein the second connecting structure may include a first internal thread 6. The second moving member 3 also has a hollow structure, and a third connecting structure is located on the inner surface of the second moving member 3, wherein the third connecting structure may include a second internal thread 7.

[0054] Please refer to Figure 1 and Figure 2 The hollow structure can be a through hole 8 formed in the first moving part 2 and the second moving part 3. The through direction of the through hole 8 is preferably the same as the axial direction of the outer cylinder 4, and the cross-sectional shape of the through hole 8 is adapted to the outer cylinder 4, for example, it is circular, so that both the first moving part 2 and the second moving part 3 can be sleeved on the outer cylinder 4 through the through hole 8. The inner surface of the first moving part 2 and the inner surface of the second moving part 3 are the hole walls of the through hole 8. The first moving part 2 is sleeved on the outer cylinder 4 and is threaded to the outer cylinder 4 through the first internal thread 6 located on the hole wall of its through hole 8. The second moving part 3 is sleeved on the outer cylinder 4 and is threaded to the outer cylinder 4 through the second internal thread 7 located on the hole wall of its through hole 8.

[0055] In actual use, the first internal thread 6 engages with the external thread 5, allowing the first moving part 2 to move on the outer cylinder 4. Once it reaches the desired position, the external thread 5 engages with the first internal thread 6 to initially position the first moving part 2. Furthermore, the second internal thread 7 engages with the external thread 5, allowing the second moving part 3 to move on the outer cylinder 4 and approach the first moving part 2. The second moving part 3 abuts against the side of the first moving part 2 furthest from the elastic element 1, thus achieving complete positioning of the first moving part 2.

[0056] In one specific embodiment, the external thread 5 is distributed along the axial direction of the outer cylinder 4, and optionally, the length of the external thread 5 can be between 3cm and 10cm. The first internal thread 6 and the second internal thread 7 can also be distributed along the axial direction of the outer cylinder 4, the length of the first internal thread 6 can be between 1cm and 2.5cm, and the length of the second internal thread 7 can be between 0.5cm and 1.5cm.

[0057] For example, the length of the external thread 5 is 4.5 cm, the length of the first internal thread 6 is 2 cm, and the length of the second internal thread 7 is 0.8 cm.

[0058] In other cases, each thread structure can be adapted to other lengths according to the movable range requirements of the first moving part 2.

[0059] In one specific embodiment, please refer to Figure 1 and Figure 2 The outer periphery of the first moving member 2 is bent toward the elastic member 1 to form a blocking part 21. The blocking part 21 is used to restrict the elastic member 1 from detaching. When the elastic member 1 wants to detach, it will be blocked by the blocking part 21.

[0060] Alternatively, please refer to Figure 4 The included angle R formed between the blocking part 21 and the first moving part 2 can be between 95° and 150°, for example, 100°.

[0061] In addition, at least one drain hole 22 is provided on the first movable member 2. Exemplarily, a plurality of drain holes 22 may be provided on the first movable member 2 at intervals along the annular direction.

[0062] In one specific embodiment, the outer cylinder 4 is provided with a lug 11 for connecting to an external vehicle. The lug 11 is located on the side of the first moving member 2 away from the elastic member 1. The lug 11 is used to position and connect the shock absorber body to the vehicle's suspension. The structure of the lug 11 is not specifically limited and can be adapted according to actual conditions and needs. Its specific structure can be referred to... Figure 1 .

[0063] In one specific embodiment, the elastic element 1 includes a helical spring, the outer diameter of the middle portion of the helical spring being larger than the outer diameters of its two ends. One end of the helical spring abuts against the first movable element 2, and the other end can indirectly abut against the vehicle body through a fixed seat (not shown in the figure).

[0064] This utility model also provides a vehicle, including a body and a shock absorber as described in any of the above embodiments. Specifically, the shock absorber is mounted on the vehicle body. Therefore, the vehicle provided by this utility model can adjust its ground clearance based on the shock absorber, allowing it to better adapt to different road conditions and meet diverse user needs.

[0065] In summary, the shock absorber provided by this utility model has one end of the elastic element abutting against the first movable element and the other end abutting against the vehicle body. The first movable element is movably fitted onto the outer cylinder. The operator can adjust the position of the elastic element by moving the first movable element, thereby flexibly adjusting the overall length of the shock absorber. This allows the shock absorber of this utility model to not only have the function of shock absorption but also the function of adjusting the vehicle body's ground clearance, meeting different user needs and solving the problem of the single function of existing shock absorbers. At the same time, adjusting the vehicle body's ground clearance by adjusting the overall length of the shock absorber is easier and more convenient to operate compared to the traditional method of replacing parts.

[0066] In addition, the shock absorber of this utility model can initially position the first moving part through the first connecting structure, and fully position the first moving part through the second moving part, which avoids the first moving part from moving due to vibration caused by external forces on the vehicle. This makes the first moving part have good stability after it is moved into place, and can play a good supporting role for the elastic element, ensuring the stable cooperation between the shock absorber and the elastic element and improving the buffering performance.

[0067] The vehicle provided by this utility model, based on the setting of the shock absorber, realizes the adjustment of the vehicle body height from the ground, which can flexibly adapt to different application scenarios and provide a better user experience.
