Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0023] Example 1 The shock absorber provided in this application can be specifically used in the rear frame of vehicles such as electric bicycles. The shock absorber can absorb the vibration generated during riding, thereby improving riding comfort.
[0024] See Figures 1 to 4 As shown, the shock absorber provided in this application includes a guiding mechanism, a damping mechanism, and an adjusting mechanism.
[0025] The guiding mechanism includes a guide rod 101 and a guide cylinder 102. The guide cylinder 102 is sleeved around the guide rod 101, and the guide rod 101 can reciprocate relative to the guide cylinder 102. One of the guide rod 101 and the guide cylinder 102 is used to connect to the frame, and the other is used to connect to the rear swingarm. The shock absorption mechanism includes a first elastic element 103 and a second elastic element 104. The first elastic element 103 is sleeved on the outside of the guiding mechanism, and its two ends are respectively connected to the guide rod 101 and the guide cylinder 102. The second elastic element 104 is installed inside the guide cylinder 102, and its two ends are respectively connected to the guide rod 101 and the guide cylinder 102.
[0026] The adjustment mechanism includes a first adjustment component and / or a second adjustment component; the first adjustment component is located between the first elastic element 103 and the guide mechanism to adjust the pre-compression amount of the first elastic element 103; the second adjustment component is located between the second elastic element 104 and the guide mechanism to adjust the pre-compression amount of the second elastic element 104.
[0027] Specifically, the first elastic element 103 and the second elastic element 104 are springs, respectively disposed outside and inside the guide mechanism, thus forming a parallel damping structure. This structure can achieve multi-level damping response, meaning that under different vibration intensities, the two elastic elements can work together, improving the adaptability and flexibility of the damping system. The dual elastic element structure can distribute the load, preventing a single elastic element from bearing excessive stress, thereby reducing fatigue damage and extending the service life of the overall damper.
[0028] The guiding mechanism consists of a guide rod 101 and a guide cylinder 102, ensuring the linearity and stability of the shock absorber during movement. The relative reciprocating motion between the guide rod 101 and the guide cylinder 102 also limits the offset and torsion of the first elastic element 103, improving structural reliability. The second elastic element 104 is concealed within the guide cylinder 102, saving space and making the overall structure more compact.
[0029] Preferably, the guiding mechanism further includes a limiting plug 105; the limiting plug 105 is installed at the opening of the guide cylinder 102 near the guide rod 101; the guide rod 101 passes through the limiting plug 105 and is capable of reciprocating relative to the limiting plug 105; a second limiting platform 106 is provided at the end of the guide rod 101, and the second limiting platform 106 can abut against the inner side of the limiting plug 105. The setting of the limiting plug 105 restricts the end of the guide rod 101 inside the guide cylinder 102, preventing the guide rod 101 from coming out of the guide cylinder 102, thus improving the structural stability of the entire guiding mechanism. Furthermore, this structure limits the stroke range of the guiding mechanism, preventing the first elastic element 103 and the second elastic element 104 from bearing excessive tensile force, thereby extending the service life of the shock absorber.
[0030] Furthermore, since the pre-compression of the elastic element directly affects its initial stiffness and response sensitivity, this application adjusts the pre-compression of the first elastic element 103 by setting a first adjustment component and adjusts the pre-compression of the second elastic element 104 by setting a second adjustment component. This enables fine adjustment of the shock absorption performance, changes the feedback state of the shock absorber when the user is riding, meets the different shock absorption needs of different groups of people, has good versatility and environmental adaptability, meets the needs of different usage scenarios or load conditions, and improves riding comfort and vehicle handling.
[0031] In an optional embodiment, the guide mechanism further includes a first connecting seat 107, which is connected to the end of the guide rod 101 away from the guide cylinder 102; the first adjustment component includes a plurality of adjustment pads 108 of different thicknesses, any one of which can be detachably installed between the first connecting seat 107 and the first elastic member 103 to pre-compress the first elastic member 103.
[0032] In this embodiment, one end of the first elastic element 103 is connected to the end of the guide rod 101 away from the guide cylinder 102, and the other end of the first elastic element 103 is connected to the end of the guide cylinder 102 away from the guide rod 101. When the guide rod 101 reciprocates relative to the guide cylinder 102, the first elastic element 103 can be compressed or stretched accordingly. The first connecting seat 107 provided on the guide rod 101 is used to connect the frame or rear swingarm to achieve structural support. By providing adjusting pads 108 of different thicknesses between the first connecting seat 107 and the first elastic element 103, the pre-compression amount of the first elastic element 103 can be adjusted, allowing users to flexibly adjust the working characteristics of the elastic element according to specific application requirements and working environment, simplifying the adjustment process.
[0033] In an optional embodiment, the adjusting pad 108 includes multiple splicing parts 109; the multiple splicing parts 109 are spliced together to form a cylindrical structure to surround the circumference of the guide rod 101; and the multiple splicing parts 109 are detachably connected to each other. Figure 1 The adjusting pad 108 shown is composed of two semi-circular splicing parts 109, which can be fixed together by snap-fit or other fastening structures. The splicing parts 109 have few parts, making them easy for users to operate. When it is necessary to replace the adjusting pad 108 with one of different thicknesses, only the new splicing parts 109 need to be disassembled and reassembled, greatly simplifying the replacement process. The cylindrical structure formed by the splicing parts 109 is fitted around the guide rod 101, allowing the guide rod 101 to position it and improving the stability of the structure.
[0034] In an optional embodiment, the shock absorption mechanism further includes a sliding ring 110; the sliding ring 110 is located between the adjusting pad 108 and the first elastic member 103, and the sliding ring 110 is connected to the first elastic member 103; the sliding ring 110 is sleeved on the circumference of the guide rod 101 and can reciprocate relative to the guide rod 101.
[0035] In this embodiment, the sliding ring 110 is connected to the first elastic element 103, which can fix the end of the first elastic element 103 to prevent it from shifting or tilting, ensuring its normal operation. Furthermore, the sliding ring 110 can evenly distribute the pressure from the first elastic element 103, avoiding localized stress concentration and improving the stability and reliability of the entire shock absorption mechanism. Figure 2As shown, when replacing the installation adjustment pad 108, the sliding ring 110 provides a gripping position for the user. The user can hold the sliding ring 110 and compress the first elastic element 103 downward to create a distance between the sliding ring 110 and the first mounting seat, making it easier to place the adjustment pad 108 between the sliding ring 110 and the first connecting seat 107.
[0036] In an optional embodiment, the guiding mechanism further includes a second connecting seat 111, which is movably connected to the end of the guide cylinder 102 away from the guide rod 101; the second adjusting assembly includes a threaded adjusting push block 112 and a driving rod 113, with the adjusting push block 112 sleeved on the driving rod 113; one end of the driving rod 113 is connected to the second connecting seat 111, and the other end of the driving rod 113 extends into the guide cylinder 102; the adjusting push block 112 is located inside the guide cylinder 102, and the second elastic element 104 is located between the guide rod 101 and the adjusting push block 112; when the second connecting seat 111 rotates relative to the guide cylinder 102, the driving rod 113 drives the adjusting push block 112 to reciprocate, so as to pre-compress the second elastic element 104.
[0037] In this embodiment, the second connecting seat 111 on the guide cylinder 102 is not only used to connect the frame or the rear swingarm, but also to adjust the second adjusting assembly inside the guide cylinder 102, so that the second adjusting assembly pre-compresses the second elastic member 104 inside the guide cylinder 102. Specifically, the second adjusting assembly includes an adjusting push block 112 and a drive rod 113. The drive rod 113 is connected to the second connecting seat 111 and extends into the guide cylinder 102. The adjusting push block 112 is provided with an internal thread, and the drive rod 113 is provided with an external thread. The adjusting push block 112 is sleeved on the outside of the drive rod 113. When the second connecting seat 111 rotates relative to the guide cylinder 102, the rotation of the drive rod 113 can drive the adjusting push block 112 to reciprocate. The second elastic member 104 is located between the guide rod 101 and the adjusting push block 112. When the adjusting push block 112 moves towards the guide rod 101, the second elastic member 104 is pre-compressed.
[0038] The pre-compression of the second elastic element 104 can be adjusted by rotating the second connecting seat 111 from the outside, which is very simple to operate. Furthermore, the relative position of the second connecting seat 111 and the first connecting seat 107 remains unchanged in the spring direction of the shock absorber, and will not affect the overall length of the shock absorber. Preferably, the second elastic element 104 is sleeved on the drive rod 113, which can position the second elastic element 104 to prevent it from shifting or tilting, ensuring its normal operation.
[0039] In this embodiment, the inner cross-section of the guide cylinder 102 is non-circular, such as square or triangular. When the drive rod 113 rotates, the inner cavity structure of the guide cylinder 102 restricts the adjusting push block 112 from rotating, so that the adjusting push block 112 can only reciprocate in the axial direction of the drive rod 113, thereby pre-compressing the second elastic element 104.
[0040] Example 2 The shock absorber in this second embodiment is an improvement on the above embodiments. The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this second embodiment.
[0041] See Figure 4 As shown, in an optional embodiment, the shock absorber further includes a limiting sleeve 114; the limiting sleeve 114 includes a connecting portion 115 and a limiting portion 116; the connecting portion 115 is connected to the guide cylinder 102; the limiting portion 116 is connected to the side of the connecting portion 115 near the second connecting seat 111, and the limiting portion 116 is located on the side of the second connecting seat 111 away from the guide cylinder 102, so as to limit the second connecting seat 111. The limiting sleeve 114 can connect the second connecting seat 111 to the guide cylinder 102, while providing space for the second connecting seat 111 to rotate. When the second connecting seat 111 rotates, the limiting sleeve 114 does not affect the rotation of the second connecting seat 111, but restricts the second connecting seat 111 to only be able to rotate horizontally, thereby causing the adjusting push block 112 in the guide cylinder 102 to reciprocate.
[0042] Specifically, the guide cylinder 102 is connected to the second connecting seat 111 at one end and is provided with a first limiting platform 117. The end of the first elastic member 103 abuts against the first limiting platform 117. The connecting part 115 surrounds the first limiting platform 117 in the circumferential direction and protrudes from the first limiting platform 117 to limit the first elastic member 103 in the circumferential direction.
[0043] In this embodiment, the first limiting platform 117 is connected to the first elastic member 103, which can fix the end of the first elastic member 103 to prevent it from shifting or tilting, ensuring its normal operation. The connecting part 115 protrudes from the first limiting platform 117, limiting the first elastic member 103 circumferentially, further preventing the first elastic member 103 from shifting laterally or tilting when subjected to external force. This ensures that the first elastic member 103 can evenly distribute pressure when compressed, reducing local stress concentration and improving its working stability.
[0044] Example 3 This application provides a vehicle in embodiment three that includes the shock absorber of any of the above embodiments, and thus has all the beneficial technical effects of the shock absorber of any of the above embodiments, which will not be repeated here.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
