[0038] Reference is made to the accompanying drawings that are included to provide a further understanding of the application, and are incorporated in and constitute a part of this specification. Figures 2-6As shown, the control component 3 includes a fixed part 301 fixedly installed in the piston cylinder 1 and located above the damping valve piston 201, a control plate 302 is rotatably installed on the fixed part 301, and three groups of through holes 306 of the same size are equidistantly arranged on the fixed part 301 and the control plate 302. By controlling the rotation of the control plate 302, the size of the misalignment gap of the through holes 306 on the fixed part 301 and the control plate 302 is adjusted, and then the flow rate of the hydraulic oil is controlled, so as to achieve the purpose of adjusting the damping. The control plate 302 is fixedly installed at the center of the control plate 302, and the connecting pipe 303 is rotatably sleeved on the piston rod 2. The end of the connecting pipe 303 is fixedly connected with the rotating ring 304, and the rotating ring 304 is located at the top of the piston cylinder 1. Specifically, the monitoring component 4 controls the rotation of the rotating ring 304, and then drives the control plate 302 to rotate on the fixed part 301 through the connecting pipe 303, so as to adjust the size of the misalignment gap of the through holes 306 on the fixed part 301 and the control plate 302.

[0039] Reference is made to the accompanying drawings Figures 4-6 As shown, the monitoring component 4 includes a hollow ring 401 fixedly installed at the top of the piston cylinder 1. The arc-shaped arrangement of the hollow ring 401 facilitates the rotation of the rotating ring 304. The sliding block 403 and the pushing block 404 are slidably installed in the hollow ring 401. Liquid is injected between the sliding block 403 and the pushing block 404. The sliding block 403 pushes the liquid to move the pushing block 404. The connecting block 4011 is arranged on the inner side of the hollow ring 401, which limits the movement range of the pushing block 404. The connecting piece 4041 is slidably inserted into the connecting block 4011, and the connecting piece 4041 is fixedly connected with the pushing block 404 and the rotating ring 304. When the pushing block 404 moves, the connecting piece 4041 drives the rotating ring 304 to rotate. The conduit 402 is fixedly connected to the bottom of the hollow ring 401 and communicates with the piston cylinder 1. When the shock absorber is impacted in the first moment, the flowing hydraulic oil enters the hollow ring 401 through the conduit 402 to push the sliding block 403. Two groups of limiting plates 405 are symmetrically installed in the hollow ring 401, and the limiting plates 405 are located between the conduit 402 and the sliding block 403. By arranging the limiting plates 405, the movement range of the sliding block 403 is limited, and the sliding block 403 is prevented from moving excessively and then blocking the communication port above the conduit 402.

[0040] Specifically, when the shock absorber is impacted in the first moment, the flowing hydraulic oil enters the hollow ring 401 through the conduit 402 to push the sliding block 403. The sliding block 403 pushes the liquid to move the pushing block 404, and then drives the connecting piece 4041 to rotate the rotating ring 304, so as to control the control component 3 to adjust the damping.

[0041] The arc-shaped groove is arranged on the positioning plate 202, and the positioning plate 202 is arranged on the arc-shaped groove, so that the user can quickly adjust the handle 4013 outside the device. The hollow ring 401 is fixedly connected with the connecting block 4011. The connecting block 4011 is fixedly installed with the connecting rod 4012. The upper end of the connecting rod 4012 is fixedly connected with the handle 4013 through the arc-shaped groove. Specifically, when the motorcycle ends the journey, the handle 4013 is pushed to move, and then the handle 4013 at the bottom of the connecting rod 4012 drives the rotating ring 304 to rotate, so that the damping in the piston cylinder 1 is adjusted back to the initial state.

[0042] The limiting component 5 is used for limiting the activity range of the control component 3, and includes a limiting piece 501 fixedly installed at the top of the piston cylinder 1. By arranging the limiting piece 501, the extension and retraction range of the compression spring 504 is limited, and the influence of the hydraulic oil on the compression spring 504 is reduced. The limiting piece 501 is slidably inserted with a positioning pin 502. The positioning pin 502 is fixedly connected with a limiting block 503. By arranging the limiting block 503, the activity range of the positioning pin 502 is limited, so that the positioning ball 5021 on the positioning pin 502 is prevented from being ejected from the limiting groove 305. The positioning pin 502 is sleeved with the compression spring 504, and the two ends of the compression spring 504 are fixedly connected with the piston cylinder 1 and the limiting block 503, respectively. By arranging the compression spring 504, the compression spring 504 gives the positioning pin 502 a thrust force that always inserts the positioning pin 502 into the clamping groove 3051. The limiting groove 305 is arranged on the control plate 302. By arranging the limiting groove 305, the rotation range of the control plate 302 is limited, so that the rotation angle is prevented from being too large, and then the through hole 306 on the control plate 302 is completely dislocated with the fixed piece 301, so that the through hole 306 loses the function, and then the hydraulic oil in the space below the fixed piece 301 and the space above the control plate 302 cannot flow, so that a damping adjustment failure occurs.

[0043] A plurality of sets of clamping grooves 3051 are equidistantly arranged in the limiting groove 305, and the clamping grooves 3051 are arranged to facilitate the positioning pin 502 to fix the control plate 302, so as to effectively avoid the connecting piece 4041 from losing the pushing force after the hydraulic oil leaves the hollow ring 401, and thus the random deflection of the control plate 302, the bottom of the positioning pin 502 is fixedly installed with a positioning ball 5021, and the end of the positioning ball 5021 is slidingly inserted into the clamping groove 3051, the arrangement of the ball end of the positioning ball 5021 helps to reduce the abrasion of the positioning ball 5021 during movement, the positioning pin 502 is inserted into the clamping groove 3051, so as to fix the rotation angle of the control plate 302, when the shock absorber encounters a greater impact force, the hydraulic oil pushes the sliding block 403, and thus the pushing block 404 continues to move towards the end of the hollow ring 401, the connecting piece 4041 drives the rotating ring 304 to rotate, the control plate 302 rotates together with the connecting pipe 303, the positioning pin 502 is lifted by the protrusion of the limiting groove 305 and is pressed against the compression spring 504, when the control plate 302 stops moving, the compression spring 504 is elastically released, the positioning pin 502 is inserted into the corresponding clamping groove 3051, and the deflection position of the control plate 302 is fixed.

[0044] When the motorcycle encounters bumps, the flowing hydraulic oil enters the hollow ring 401 through the conduit 402 to push the sliding block 403 in the first moment of impact, the sliding block 403 pushes the liquid, and thus the pushing block 404 moves with the pushing force, the connecting piece 4041 drives the rotating ring 304 to rotate together, the connecting pipe 303 on the rotating ring 304 drives the control plate 302 to rotate, and thus the misalignment gap size of the through hole 306 on the fixed part 301 and the control plate 302 is adjusted, so as to achieve the effect of adjusting the damping.

[0045] When the control plate 302 rotates, the positioning pin 502 is lifted by the protrusion of the limiting groove 305 and is pressed against the compression spring 504, when the control plate 302 stops moving, the compression spring 504 is elastically released, the positioning pin 502 is inserted into the corresponding clamping groove 3051, and the deflection position of the control plate 302 is fixed, when the motorcycle ends the journey, the pushing handle 4013 moves, and thus the rotating ring 304 is driven to rotate back to the original position through the handle 4013 at the bottom of the connecting rod 4012, so as to adjust the damping in the piston cylinder 1 back to the initial state, so as to adjust the damping to the impact strength suitable for different road conditions.

[0046] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the same; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
