Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle shock absorption equipment, and in particular to a motorcycle rear shock absorber that is easy to adjust. Background Technology

[0002] Motorcycles are widely used as a convenient means of transportation in daily commutes and outdoor riding. The rear shock absorber is the core component of the motorcycle suspension system, and its performance directly affects the motorcycle's ride comfort, stability, and safety. Different road conditions (such as smooth highways and bumpy mountain roads), different rider weights, and different riding needs (such as commuting and off-roading) place different requirements on the installation position and shock absorber travel of the motorcycle's rear shock absorber.

[0003] The patent publication number "CN220523161U" discloses "An Adjustable Motorcycle Rear Shock Absorber," which includes an upper connector and a lower connector. A piston rod is screwed to the lower part of the upper connector, and an outer cylinder is screwed to the top right side of the lower connector. An oil seal assembly and an outer cylinder cap are sequentially installed from bottom to top on the inner side of the top of the outer cylinder. An inner cylinder is located inside the outer cylinder, and a guide sleeve is installed at the top of the inner cylinder. A piston assembly and a buffer spring are sequentially installed from bottom to top on the bottom of the piston rod. The piston assembly is fitted inside the inner cylinder. The adjustable downward screw plug assembly and the adjustable rebound screw plug assembly are respectively equipped with a flathead downward adjusting screw and a flathead rebound adjusting screw. This utility model utilizes a guide sleeve connection for the inner cylinder installation, ensuring verticality and preventing the inner cylinder from becoming non-vertical. This results in smooth piston movement, good shock absorption, and good user comfort. Furthermore, it can be adjusted with a flathead screwdriver, making the adjustment tool widely available and convenient to use.

[0004] The aforementioned motorcycle rear shock absorber adjustment methods are quite complex, often requiring multiple tools and involving repeated disassembly and calibration, making the process cumbersome and time-consuming. Some shock absorbers also suffer from poorly designed adjustment structures, resulting in insufficient adjustment precision and difficulty in accurately adapting to different usage scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide a conveniently adjustable motorcycle rear shock absorber, which solves the problems of the existing motorcycle rear shock absorber adjustment method being relatively complicated, mostly requiring the use of multiple tools, and requiring repeated disassembly and calibration during the adjustment process, which is cumbersome and time-consuming.

[0006] To achieve the above objectives, this utility model provides a conveniently adjustable motorcycle rear shock absorber, including a shock absorber body. One end of the shock absorber body is provided with a position adjustment component; the other end of the shock absorber body is provided with an auxiliary adjustment component. The position adjustment component includes a docking box, which is fixedly connected to one side of the motorcycle. A translation screw is rotatably connected between the inner walls of the docking box. A nut block is threadedly connected to the outer wall of the translation screw. A first concave block is fixedly connected to the bottom of the nut block. One end of the shock absorber body is rotatably connected to the inner wall of the first concave block. A hexagonal insertion hole is opened inside one end of the translation screw.

[0007] The nut block is cubic in shape and is slidably connected to the inner wall of the docking box.

[0008] The hexagonal socket is equipped with a corresponding hexagonal wrench.

[0009] The nut block has a first threaded hole on one side, and the docking box has a first through hole on one side. The first through holes are distributed in a straight line array along the docking box. The position adjustment component also includes a first bolt, which passes through the first through hole and is threadedly connected to the first threaded hole.

[0010] The auxiliary adjustment component includes a sleeve, which is fixedly connected to one end of the shock absorber body, and a second through hole is provided on one side of the sleeve.

[0011] The sleeve has a slider slidably connected inside, and a second threaded hole is provided on one side of the slider. The second threaded holes are distributed in an array along the direction of the slider.

[0012] The slider is rectangular in shape, and the auxiliary adjustment component also includes a second bolt. The second bolt passes through a second through hole and is internally threaded into a second threaded hole. A protrusion is fixedly connected to one end of the slider.

[0013] The auxiliary adjustment component also includes a pad, which is fixedly connected to the rear interface of the motorcycle. A second concave block is fixedly connected to the top of the pad, and the inner wall of the second concave block is rotatably connected to one end of the protrusion.

[0014] Beneficial effects Compared with existing technologies, it has the following advantages: 1. This utility model achieves dual adjustment of the shock absorber body by setting a position adjustment component and an auxiliary adjustment component. The adjustment range is wide, precisely adaptable to different road conditions, riders of different weights, and different riding needs, greatly improving the motorcycle's riding comfort and adaptability. The position adjustment component includes a translation screw, a hexagonal socket, and a matching hexagonal wrench. Only a single tool is needed to drive the translation screw to rotate, thereby causing the nut block to translate, achieving position adjustment at one end of the shock absorber body. Operation is simple and quick, requiring no complex disassembly.

[0015] 2. In this utility model, the nut block is designed as a cube and slides along the inner wall of the docking box, while the slider is designed as a rectangle and slides along the sleeve. This effectively prevents the components from rotating during adjustment, ensuring adjustment accuracy and guaranteeing the accurate adjustment position of the shock absorber body. The first bolt passes through the first through hole and is threaded into the first threaded hole, and the second bolt passes through the second through hole and is threaded into the second threaded hole. This double-bolt fixing structure firmly locks the adjusted position, preventing the components from loosening due to vibration or other factors during use, thus improving the stability and safety of the shock absorber.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Reference Figure 1 , Figures 3-6This utility model provides a technical solution: a conveniently adjustable rear shock absorber for motorcycles, comprising a shock absorber body 1. The shock absorber body 1 adopts a mature and reliable hydraulic or spring-type shock absorption structure, internally equipped with a high-precision damper and a high-strength shock-absorbing spring, which can effectively absorb the impact force from the road surface during motorcycle riding, providing stable basic shock absorption and buffering functions, significantly reducing the impact of vibration on the rider, and ensuring riding comfort and stability. One end of the shock absorber body 1 is provided with a position adjustment component 2, which is specifically used to precisely adjust the horizontal position of this end of the shock absorber body 1. By changing the installation point of the shock absorber on the side of the motorcycle, it adapts to different frame stress requirements. The other end of the shock absorber body 1 is provided with an auxiliary adjustment component 3, mainly used to flexibly adjust the extension length of this end of the shock absorber body 1, thereby cooperating with the position adjustment component 2 to achieve comprehensive optimization of the overall shock absorption stroke, force angle, and shock absorption stiffness, meeting the shock absorption needs under diverse riding scenarios. The position adjustment assembly 2 includes a docking box 21, which is integrally stamped from high-strength alloy steel. This material possesses excellent tensile strength and deformation resistance, enabling it to withstand the continuous forces generated during shock absorber operation. The docking box 21 is fixedly connected to a pre-set mounting base on one side of the motorcycle frame using four high-strength fastening bolts. Anti-loosening washers and lock nuts are provided at the bolt connections to effectively prevent loosening due to long-term vibration, ensuring a secure, reliable, and durable connection. A translation screw 22 is rotatably connected between the inner walls of the docking box 21 via high-precision ball bearings. The ball bearings significantly reduce the frictional resistance of the translation screw 22 during rotation, making the adjustment process smoother and less strenuous, while also improving rotational accuracy. The outer wall of the translation screw 22 is provided with a precision trapezoidal thread, which precisely meshes with the inner thread of the nut block 23. The nut block 23 is designed as a standard cube, and its outer wall is slidably connected to the inner wall of the docking box 21 via a precision slide rail. The cube structure and the slide rail can strictly limit the rotational freedom of the nut block 23, allowing it to only make smooth horizontal translational movements along the inner wall of the docking box 21, avoiding deviation or jamming during adjustment. The bottom of the nut block 23 is fixedly connected to the first concave block 24 by welding. The weld is inspected for flaws to ensure that the connection strength meets the standards. The inner walls of the first concave block 24 are rotatably connected to one end of the shock absorber body 1 via a high-hardness alloy rotating shaft. Both ends of the rotating shaft are equipped with wear-resistant bushings and dustproof sealing rings, which not only ensures that the shock absorber body 1 can rotate flexibly during adjustment to adapt to different installation angle changes, but also effectively prevents dust, mud, water and other debris from entering the rotating connection, extending its service life.One end of the translation screw 22 has a standard hexagonal socket 28. The inner wall of the hexagonal socket 28 is polished to reduce wear when engaging with a wrench. A dedicated extended hexagonal wrench is included; this wrench is forged from CR-V alloy steel, offering high strength and stable torque transmission. By precisely inserting the hexagonal wrench into the hexagonal socket 28 and rotating it, the translation screw 22 can be easily driven to rotate without the need for additional complex tools, making operation simple and efficient. One side of the nut block 23 has a first threaded hole 25 with an internal thread precision of 6H. The inner wall of the threaded hole is smooth and burr-free, ensuring precise engagement with the bolt. One side of the docking box 21 has multiple first through holes 26 along its length. These first through holes 26 are evenly distributed in a linear array. The spacing between adjacent through holes is scientifically calculated, allowing for multi-level fine-tuning of the shock absorber's horizontal position to meet different precision adjustment needs. The position adjustment assembly 2 also includes a first bolt 27 that fits into the first threaded hole 25. The first bolt 27 is made of high-strength carbon steel and is galvanized for rust prevention, providing excellent corrosion resistance. When the nut block 23 moves to the target position, the first bolt 27 is passed through the corresponding first through hole 26 on the docking box 21 and tightly threaded into the first threaded hole 25 on the nut block 23. After tightening the first bolt 27, the bolt head fits tightly against the outer wall of the docking box 21, forming a reliable locking and fixing mechanism. This effectively prevents the nut block 23 from shifting due to severe vibrations during motorcycle operation, ensuring the stability of the adjustment position.

[0021] Reference Figures 1-3 , Figures 5-6 In one aspect of this embodiment, the auxiliary adjustment component 3 includes a sleeve 31 made of high-strength alloy material, fixedly connected to one end of the shock absorber body 1. A second through hole 32 is provided on one side of the sleeve 31. A slider 34 is slidably connected inside the sleeve 31. The slider 34 is rectangular in shape to prevent the slider 34 from rotating inside the sleeve 31, ensuring the smoothness of the sliding process. A second threaded hole 35 is provided on one side of the slider 34. The second threaded holes 35 are arrayed along the direction of the slider 34. The auxiliary adjustment component 3 also includes a second bolt 33, which passes through the second through hole 32 and is threadedly connected to the inside of the second threaded hole 35. By selecting different positions of the second threaded hole 35 and the second through hole 32 for alignment and fixing, the length of the slider 34 extending out of the sleeve 31 can be adjusted. One end of the slider 34 is fixedly connected to the protrusion 36. The auxiliary adjustment component 3 also includes a pad 38. The pad 38 is fixedly connected to the rear interface of the motorcycle by bolts. The top of the pad 38 is fixedly connected to the second concave block 37. The inner wall of the second concave block 37 is rotatably connected to one end of the protrusion 36 through a rotating shaft, so as to ensure that the shock absorber body 1 can swing flexibly with the motorcycle's driving state during operation.

[0022] Working Principle: This easily adjustable motorcycle rear shock absorber allows for adjustment of the shock absorber body 1 according to actual riding needs via the position adjustment component 2 and auxiliary adjustment component 3. When adjusting the horizontal position of one end of the shock absorber body 1, first loosen the first bolt 27, disengaging it from the first threaded hole 25 on the nut block 23, thus releasing the fixing constraint on the nut block 23. Insert the matching hex wrench into the hexagonal socket 28 at one end of the translation screw 22, and rotate the hex wrench, causing the translation screw 22 to rotate within the inner wall of the docking box 21. Since the nut block 23 is threadedly connected to the translation screw 22 and its rotation is restricted, the rotation of the translation screw 22 is converted into horizontal displacement of the nut block 23 along the inner wall of the docking box 21. The nut block 23 drives the first concave block 24 at the bottom to move synchronously, thereby pulling one end of the shock absorber body 1 horizontally, achieving position adjustment. After the shock absorber body 1 is moved to the target position, stop turning the hex wrench, pass the first bolt 27 through the corresponding first through hole 26 on the docking box 21, and thread it into the first threaded hole 25 on the nut block 23. Tighten the first bolt 27 to complete the fixation after position adjustment. When it is necessary to adjust the extension length of the shock absorber body 1 to optimize the shock absorption effect, loosen the second bolt 33 so that the second bolt 33 disengages from the second threaded hole 35 on the slider 34, releasing the fixation of the slider 34. Push or pull the protrusion 36 as needed to drive the slider 34 to slide inside the sleeve 31, adjust the length of the slider 34 extending out of the sleeve 31, and thus change the overall effective shock absorption stroke of the shock absorber body 1. After the slider 34 is adjusted to the appropriate position, align the second through hole 32 on the sleeve 31 with the corresponding second threaded hole 35 on the slider 34, pass the second bolt 33 through the second through hole 32 and thread it into the second threaded hole 35, and tighten the second bolt 33 to complete the fixation after auxiliary adjustment.

[0023] During motorcycle operation, the shock absorber body 1 is flexibly adapted to road bumps by rotating the first concave block 24 and the second concave block 37 at both ends. At the same time, the bolt fixing structure of the position adjustment component 2 and the auxiliary adjustment component 3 ensures the overall stability of the shock absorber, prevents the adjustment position from loosening, and ensures driving safety.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
