Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the present application and its practical application, and to enable others skilled in the art to understand the present application in order to design various embodiments with various modifications for specific use cases.

[0018] Embodiment: Please refer to Figure 1 Figure 4 The utility model provides a technical scheme: a shock absorbing range adjustable motorcycle shock absorber, it includes: cylinder 1, the inner wall sliding joint of cylinder 1 has telescopic link 2, the outer wall fixed connection of telescopic link 2 has spring 3, the outer wall fixed connection of cylinder 1 top has limit cap 4;Adjusting device 5, the outer wall of adjusting device 5 is connected with the inner wall of limit cap 4 rotationally;Extrusion device 6, the outer wall of extrusion device 6 is connected with the outer wall of cylinder 1 slidingly;

[0019] Adjusting device 5 includes rotating ring 51, the side wall fixed connection of rotating ring 51 inside has connecting ring 52, the outer wall of connecting ring 52 is set with gear slot 53, the inner wall of rotating ring 51 is provided with driven gear 54, the inner wall fixed connection of driven gear 54 has screw rod 55, the outer wall rotationally connected of driven gear 54 bottom has anti-off device 56, setting adjusting device 5 plays a role, when rotating ring 51 inside the gear slot 53 of connecting ring 52 is engaged with driven gear 54, so the rotation of rotating ring 51 will drive driven gear 54 to rotate, driven gear 54 drives the rotation of fixed axle position screw rod 55, and screw rod 55 is connected with the sliding ring 61 in extrusion device 6 through screw hole 62 thread, when screw rod 55 rotates, sliding ring 61 will be pushed along the outer wall of cylinder 1 and moves up and down.

[0020] Connecting ring 52 is engaged with the outer wall of driven gear 54 through gear slot 53, the outer wall of screw rod 55 top is rotationally connected with the inner wall of limit cap 4, and the inner wall of limit cap 4 is rotationally connected with the outer wall of rotating ring 51.

[0021] ​The extrusion device 6 comprises a sliding ring 61, a threaded hole 62 is formed in the wall of the sliding ring 61, the outer wall of the bottom of the sliding ring 61 is fixedly connected with the outer wall of the top of the spring 3, the side wall in the interior of the sliding ring 61 is slidably connected with the outer wall of the cylinder body 1, and the inner wall of the sliding ring 61 is threadedly connected with the outer wall of the screw rod 55 through the threaded hole 62. Since the telescopic rod 2 is at the maximum extension length when not being extruded, when the screw rod 55 drives the sliding ring 61 to move downwards, the sliding ring 61 will compress the spring 3 in cooperation with the telescopic rod 2 that cannot be extended, so that the pre-tightening force of the spring 3 is increased, and at this time, the damping amplitude of the motorcycle shock absorber is reduced. When the screw rod 55 reversely rotates, the sliding ring 61 moves upwards, the pre-tightening force of the spring 3 is reduced, so that the damping amplitude of the shock absorber is increased.

[0022] The anti-disengagement device 56 comprises a fixed ring 561, a limiting hole 562 is formed in the wall of the fixed ring 561, the side wall in the interior of the fixed ring 561 is fixedly connected with the outer wall of the cylinder body 1, the inner wall of the fixed ring 561 is rotatably connected with the outer wall of the screw rod 55 through the limiting hole 562, and the outer wall of the top of the fixed ring 561 is rotatably connected with the outer wall of the bottom of the driven gear 54. The fixed ring 561 in the anti-disengagement device 56 ensures the stable rotation of the screw rod 55 through the limiting hole 562, prevents the screw rod 55 from moving in the rotation process, and ensures the reliability of the whole adjustment process.

[0023] Working principle:

[0024] During the driving of the motorcycle, when the road surface is bumpy, the impact force of the road surface will make the telescopic rod 2 slide up and down in the cylinder body 1, and the spring 3 will play a buffering role and absorb part of the impact force, so that damping is realized.

[0025] In order to realize the adjustment of the damping amplitude, the adjustment device 5 is arranged to play a role. When the rotating ring 51 in the limiting cover 4 is rotated, since the tooth-shaped groove 53 of the connecting ring 52 in the rotating ring 51 is engaged with the driven gear 54, the rotation of the rotating ring 51 will drive the driven gear 54 to rotate, the driven gear 54 drives the screw rod 55 to rotate, and the screw rod 55 is threadedly connected with the sliding ring 61 in the extrusion device 6 through the threaded hole 62. When the screw rod 55 rotates, the sliding ring 61 will be pushed to move up and down along the outer wall of the cylinder body 1. Since the telescopic rod 2 is at the maximum extension length when not being extruded, when the screw rod 55 drives the sliding ring 61 to move downwards, the sliding ring 61 will compress the spring 3 in cooperation with the telescopic rod 2 that cannot be extended, so that the pre-tightening force of the spring 3 is increased, and at this time, the damping amplitude of the motorcycle shock absorber is reduced. When the screw rod 55 reversely rotates, the sliding ring 61 moves upwards, the pre-tightening force of the spring 3 is reduced, so that the damping amplitude of the shock absorber is increased.

[0026] The fixed ring 561 in the anti-disengagement device 56 ensures the stable rotation of the screw rod 55 through the limiting hole 562, prevents the screw rod 55 from moving in the rotation process, and ensures the reliability of the whole adjustment process.

[0027] By adjusting the setting of the adjusting device 5, the user can flexibly adjust the damping amplitude according to different road conditions and driving needs. When driving at high speed on flat road, the damping amplitude can be adjusted small, so that the motorcycle has better controllability and stability. When driving on bumpy road or off-road, the damping amplitude is adjusted large, the damping effect is enhanced, the driving comfort is improved, different use scenes are adapted, and the comprehensive performance and driving experience of the motorcycle are improved. And the structure is simple, convenient to operate, and easy for the user to adjust the shock absorber individually.

[0028] Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by ordinary skilled in the art and related fields without creative labor shall belong to the scope of protection of the present application. The structures, devices and operation methods not specifically described and explained in the present application, if not specially described and limited, are implemented according to the conventional means in the art.
