[0021] The top of the locking nut 34 is press-fitted with the bottom of the rotating shell 32, the top of the buffer bag 38 is fixedly connected with the bottom of the sliding column 37, and the bottom of the top spring 36 is fixedly connected with the top of the top block 24; when an impact force is applied, the buffer bag 38 can rely on the elasticity and compressibility of the internal gas or liquid to assist the top spring 36 to buffer and absorb the impact force, and the damping effect is further optimized.

[0022] Working principle:

[0023] The length-adjustable motorcycle rear shock absorber mainly comprises a ring body 1, an adjusting assembly 2 and a buffer assembly 3, and each part cooperates with each other to realize the adjustment of the length position and the softness and hardness of the shock absorber, and thus suitable damping effect is provided for the motorcycle in different riding scenes, and the stability and comfort of riding are ensured.

[0024] The ring body 1 is used as a basic component for connecting the entire shock absorber with the motorcycle frame or other related components, plays a role in stable installation, can reliably fix the shock absorber on the corresponding position of the motorcycle, lays a stable foundation for the functions of the subsequent adjusting assembly 2 and buffer assembly 3, and ensures that the entire shock absorber will not be loose or dislocated during the working process.

[0025] The adjusting assembly 2 is located above the ring body 1 and is fixedly connected with the ring body 1, and is mainly responsible for adjusting the length position of the shock absorber. The fixed shell 21 is an important component of the adjusting assembly 2. The bottom inner wall of the fixed shell 21 is rotationally connected with the limiting shell 22, so that the limiting shell 22 can rotate relative to the fixed shell 21. The inner wall at the bottom of the limiting shell 22 is slidably connected with the top block 24 through the pull spring 23. One end of the pull spring 23 is fixed to the inner wall at the top of the top block 24, and the other end is fixed to the inner wall of the limiting shell 22. The outer wall of the top block 24 is also fixedly connected with the limiting columns 25 arranged in an annular array. These limiting columns 25 are interlocked with the stepped grooves 26 formed in the inner wall of the fixed shell 21. When the length position of the shock absorber needs to be adjusted, the limiting columns 25 on the top block 24 are gripped and slid upward, and the position of the limiting columns 25 in the stepped grooves 26 is changed. Through the action of external force, the limiting shell 22 rotates relative to the fixed shell 21. During the rotation process, due to the elastic action of the pull spring 23 and the interlocking relationship between the limiting columns 25 and the stepped grooves 26, the top block 24 will slide along the inner wall of the limiting shell 22, the pull spring 23 will be stretched or contracted, and the limiting columns 25 will move to different positions along the stepped grooves 26, so as to change the height of the adjusting assembly 2 as a whole. Because the position of the limiting columns 25 in the stepped grooves 26 changes, the height position also changes synchronously, so as to change the length between the adjusting assembly 2 and the buffer assembly 3, that is, the length of the shock absorber is changed, and the length position of the entire shock absorber is adjusted. This way of rotating and relying on the cooperation of the pull spring 23 and the limiting structure makes the height adjustment operation more convenient, and can keep the corresponding height state after adjustment by relying on the interaction between the components, so as to meet the needs of different riders for the seat height of the motorcycle or the ground clearance of the vehicle under different riding conditions.

[0026] The buffer assembly 3 is located above the adjusting assembly 2 and is fixedly connected with the adjusting assembly 2, and is mainly used for adjusting the softness and hardness of the shock absorber to adapt to different road impact forces. The fixed cylinder 33 is a key structure of the buffer assembly 3, the inner wall of the fixed cylinder 33 is in sliding connection with the sliding column 37, the top of the sliding column 37 is fixedly connected with the fixed ring 35, the bottom of the fixed ring 35 is fixedly connected with the top spring 36, the bottom of the top spring 36 is fixedly connected with the top block 24 in the adjusting assembly 2, and the inner wall of the bottom of the fixed cylinder 33 is also fixedly connected with the buffer bag 38, the top of the buffer bag 38 is fixedly connected with the bottom of the sliding column 37, in addition, the top of the fixed ring 35 is in threaded connection with the rotating shell 32 through the threaded column first, and then the bottom of the rotating shell 32 is pressed and fixed by the locking nut 34, and the top of the rotating shell 32 is in rotational connection with the limiting ring 31, when it is needed to change the softness and hardness of the shock absorber, the rotating shell 32 is rotated, due to the threaded connection, the fixed ring 35 moves along the axial direction of the threaded column, and then the initial compression state of the top spring 36 is changed, so that the top spring 36 is further compressed or appropriately relaxed, the elastic potential energy change characteristics and response speed of the top spring 36 when the impact force is received are changed, and therefore the adjustment of the softness and hardness of the shock absorber is realized, and at the same time, the buffer bag 38 also changes in extension and contraction corresponding to the movement of the sliding column 37, when the impact force is received, the buffer bag 38 can rely on the elasticity and the compressibility of the internal gas or liquid to assist the top spring 36 to buffer and absorb the impact force, and the shock absorption effect is further optimized, so that the shock absorber can be adjusted to the appropriate softness and hardness according to different road conditions such as flat roads and bumpy dirt roads in the actual riding process, and good shock absorption protection is provided for the motorcycle, and the riding stability is improved.

[0027] In the whole driving process of the motorcycle, the shock absorber is first adjusted to the appropriate length position by the adjusting assembly 2, and then the appropriate softness and hardness is adjusted by the buffer assembly 3 according to the actual road conditions, and various impact forces from the road are jointly coped with by the assemblies according to the working principles, so that the shock absorber can normally play a role, the stability of the motorcycle in riding is maintained, and the riding needs of the rider in different scenes are met.
