Description

Technical Field

[0001] The utility model relates to the field of electric vehicle front forks, in particular to an adjustable sliding sleeve assembly for electric vehicle front forks. Background Art

[0002] The electric vehicle front fork is a part of the electric vehicle frame. It connects the frame and the wheel and is located in the front of the electric vehicle. The main function of the front fork is to support the front wheel, enable the vehicle to turn, and absorb the impact from the ground during driving to improve the riding comfort.

[0003] According to the Chinese patent authorization announcement: CN215399143U, a plastic part assembly for an electric vehicle front fork disclosed therein includes a front fork tube, a plastic part, a damping system, and a sliding sleeve system. The bottom of the front fork tube is connected through the plastic part. A damping system is arranged at the bottom of the plastic part. A sliding sleeve system is sleeved outside the damping system. A copper shaft is arranged in the inner cavity of the damping system. A spring is arranged outside the copper shaft. A buffer shaft is arranged at the bottom of the copper shaft. A sleeve is arranged outside the spring. The diameter of the spring is larger than that of the copper shaft and smaller than that of the sleeve. When the assembly needs to be used, the front fork tube and the plastic part can be connected through the cooperation of a round shaft and a round pad, so as to stably control the forward direction of the electric vehicle. Then, through the cooperation of the copper shaft and the spring in the inner cavity of the damping system and the sliding sleeve system, it can ensure the safety of the impact of the forward inertia of the human body when the electric vehicle is riding. The buffer shaft is conical, which can greatly reduce mechanical wear, thereby improving the service life of the electric vehicle front fork. However, there are still deficiencies in this front fork sliding sleeve assembly. Specifically, during the use of these assemblies, although they can achieve basic support and partial adjustment functions, they often lack the ability to adjust the damping amplitude. This means that regardless of whether the rider is facing a flat road or a rough off-road road surface, the damping effect provided by the front fork sliding sleeve assembly is fixed and cannot be adjusted according to actual needs. This design with a fixed damping amplitude limits the comfort and controllability of the rider under different road conditions, thereby affecting the overall riding experience. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an adjustable sliding sleeve assembly for an electric vehicle front fork, which solves the problem that although the traditional assembly can achieve basic support and partial adjustment functions during use, it often lacks the ability to adjust the damping amplitude. This means that regardless of whether the rider is facing a flat road or a rough off-road road surface, the damping effect provided by the front fork sliding sleeve assembly is fixed and cannot be adjusted according to actual needs.

[0014] The utility model provides an adjustable front fork sliding sleeve assembly for an electric vehicle. Compared with the prior art, the following beneficial effects are achieved:

[0015] In this utility model, through the provided adjustment structure, when it is necessary to adjust the damping amplitude of the front fork sliding sleeve assembly of the electric vehicle, by rotating the adjustment handle, the adjustment rod is driven to rotate, so that the adjustment plate rises or falls on the surface of the telescopic rod. When the adjustment plate rises, the distance between the adjustment plate and the fixed bottom plate is increased, so that the compression and reset distances of the damper and the first spring structure and the second spring structure on the surface are increased, effectively increasing the damping amplitude of the electric vehicle, significantly improving the riding comfort and safety. When the adjustment plate falls, the distance between the adjustment plate and the fixed bottom plate is reduced, so that the compression and reset distances of the damper and the first spring structure and the second spring structure on the surface are reduced, effectively reducing the damping amplitude, making the electric vehicle lighter and more responsive, and improving energy efficiency. This design improves the overall performance of the electric vehicle and meets different road conditions and riding requirements;

[0016] 2. In this utility model, through the provided positioning structure, before adjusting the distance between the adjustment handle and the fixed bottom plate, the positioning bolts inside the upper positioning hole and the lower positioning hole are screwed out, so that the adjustment handle can rotate freely. After adjusting the damping amplitude of the front fork sliding sleeve assembly of the electric vehicle, the positioning bolts are re-screwed into the upper positioning hole and the lower positioning hole, thereby preventing the adjustment handle from rotating due to the vibration during the driving of the electric vehicle, causing the problem of incorrect adjustment of the damping amplitude, ensuring the stability and accuracy of the damping amplitude adjustment, preventing incorrect adjustment during driving, and improving the safety and reliability of the electric vehicle. By installing a rubber gasket between the positioning bolt and the upper positioning hole, the loosening of the bolt caused by the vibration during the driving of the electric vehicle is effectively avoided, ensuring the stability of the positioning bolt.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides two technical solutions, specifically including the following embodiments: Embodiment

[0025] An adjustable front fork sliding sleeve assembly for an electric vehicle, comprising a front fork mechanism 1. The front fork mechanism 1 includes a fixed top plate 103 and a fixed bottom plate 105. Both ends of the lower surface of the fixed bottom plate 105 are fixedly connected with fixed bottom rods 106. The upper end inside the fixed bottom rod 106 is slidably connected with a telescopic rod 104. The top end of the telescopic rod 104 is fixedly connected to both ends of the lower surface of the fixed top plate 103. By the telescopic rod 104 ascending and descending inside the fixed bottom rod 106, and through the stretching and resetting of the second spring structure 203 on the surface of the telescopic rod 104, the shock absorption function during the driving of the electric vehicle is realized. An adjustment structure 3 is installed between the fixed top plate 103 and the fixed bottom plate 105. The adjustment structure 3 includes an adjustment plate and an adjustment rod 301. The adjustment plate is slidably connected to the surface of the telescopic rod 104. The adjustment rod 301 is rotatably connected through the surface of the fixed top plate 103. The adjustment plate is threadedly connected to the surface of the adjustment rod 301. The upper surface of the adjustment rod 301 is fixedly connected with an adjustment handle 303. A shock absorption structure 2 is installed between the adjustment plate and the fixed bottom plate 105. The shock absorption structure 2 includes a damper 201 and a second spring structure 203. A second spring structure 203 is arranged between the upper surfaces of the adjustment plate and the fixed bottom plate 105. The second spring structure 203 is arranged on the surface of the telescopic rod 104. By the damper 201, it prevents the electric vehicle from vibrating when not driving. Through the reset elastic force of the second spring structure 203 and the first spring structure 202, the shock absorption during the driving process is realized. The adjustment rod 301 is a long threaded rod structure. The lower surface of the adjustment rod 301 is fixedly connected with a limiting block 302. Both ends of the upper surface of the fixed top plate 103 are fixedly connected with fixed top rods 101. The surface of the fixed top rod 101 is fixedly connected with a handlebar 102 through which the steering function of the electric vehicle is realized.

[0026] When using the adjustable front fork sliding sleeve assembly for an electric vehicle, first, rotate the adjustment rod 301 through the adjustment handle 303 to make the adjustment plate slide up and down on the surface of the telescopic rod 104 to adjust the distance between the adjustment plate and the fixed bottom plate 105. Then, when the adjustment plate rises, it increases the compression and reset distance of the second spring structure 203, thereby increasing the shock absorption amplitude; when the adjustment plate descends, it reduces the compression and reset distance of the second spring structure 203, reducing the shock absorption amplitude. After the adjustment is completed, to ensure the stability of the adjustment structure 3, it is necessary to threadedly screw the positioning bolt 403 into the upper positioning hole 401 and the lower positioning hole 402 to prevent the adjustment handle 303 from being misadjusted due to vibration during driving. Finally, control the steering of the electric vehicle through the handlebar 102. At the same time, during driving, the damper 201 and the second spring structure 203 act together to absorb road vibrations and provide a comfortable riding experience. When the electric vehicle stops driving, the damper 201 can also prevent the vehicle from vibrating unnecessarily. Embodiment

[0027] On the basis of the first embodiment, a positioning structure 4 is mounted on the surface of the adjusting handle 303. The positioning structure 4 includes a positioning bolt 403. A plurality of upper positioning holes 401 are formed through the surface of the adjusting handle 303. The plurality of upper positioning holes 401 are evenly distributed on the surface of the adjusting handle 303. A lower positioning hole 402 is formed in the surface of the fixed top plate 103. The positioning bolt 403 is threadedly connected inside the upper positioning hole 401 and the lower positioning hole 402. A rubber gasket 404 is arranged between the positioning bolt 403 and the upper positioning hole 401. By means of the rubber gasket 404 installed between the positioning bolt 403 and the upper positioning hole 401, loosening of the positioning bolt 403 caused by vibration during the running of the electric vehicle can be avoided, ensuring the stability of the positioning bolt 403. A mudguard 107 is fixedly connected to the inner surface of the fixed bottom rod 106. A damper 201 is arranged between the fixed bottom plate 105 and the adjusting plate. A plurality of dampers 201 are provided. A first spring structure 202 is arranged on the surface of each of the plurality of dampers 201;

[0028] When using the adjustable front fork sliding sleeve assembly of the electric vehicle, first, adjust the shock absorption amplitude according to needs. By rotating the adjusting handle 303, the adjusting plate is moved up and down along the telescopic rod 104 to adjust the distance from the fixed bottom plate 105. During the adjustment, the positioning bolt 403 can be first screwed out of the upper positioning hole 401. After the adjustment is completed, the positioning bolt 403 is re-threadedly connected to the upper positioning hole 401 and the lower positioning hole 402 on the fixed top plate 103, and at the same time, ensure that the rubber gasket 404 is located between the positioning bolt 403 and the upper positioning hole 401 to prevent the bolt from loosening due to vibration during driving. Next, the inner structure is protected from mud and water by the mudguard 107 inside the fixed bottom rod 106. At the same time, the damper 201 between the adjusting plate and the fixed bottom plate 105 and the first spring structure 202 on its surface act together to absorb and reduce the vibration during driving, improving the riding comfort. Finally, during driving, if encountering different road conditions, the shock absorption amplitude can be finely adjusted at any time through the adjusting handle 303 to adapt to environmental changes and ensure riding stability and safety.

[0029] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the application shall be included within the protection scope of the present application.
