[0002] The front fork component is located in the front part of the electric vehicle structure. Its upper end is connected to the handlebar component, the frame component cooperates with the front tube, and the lower end cooperates with the front axle component to form the guidance system of the electric vehicle. The working order of the front fork should be: encountering an obstacle - the front fork is compressed - to the extreme - rebounded to the original length (the rebound speed is affected by the damping) - the rebound system finishes working. No matter what front fork is used, the inner tube must be kept clean.

[0003] When the front fork shock absorption of an electric vehicle is used without adjusting the stroke according to the road conditions, it may affect the riding experience, because the length of the shock absorption stroke directly affects the shock absorption effect and the rider's feeling. The shock absorption stroke refers to the distance that the front fork can move when compressed. The existing shock absorption stroke is not adjustable. When facing different road conditions, the front fork will cause excessive sensitivity. Even a small change in the road surface will cause a large bounce, which may make the rider feel uncomfortable and affect the riding stability. Therefore, an electric vehicle front fork shock absorption device with adjustable stroke is proposed to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1 to 4 In this embodiment, a front fork shock absorbing device of an electric vehicle with adjustable stroke includes a front fork connecting frame 1, a front fork sleeve 2 and an adjusting component 3.

[0023] Two fork rods 101 are provided below the front fork connecting frame 1 , the front fork sleeve 2 is provided outside the two fork rods 101 , and the adjustment assembly 3 is provided on the left and right sides of the front fork sleeve 2 .

[0024] Example 2: Please refer to Figures 2 to 4 On the basis of the first embodiment, in order to facilitate the adjustment of the front fork shock absorption stroke, the adjustment assembly 3 in this embodiment includes two adjustment boxes 31, which are respectively arranged on the left and right sides of the front fork sleeve 2. A stroke adjustment plate 32 is slidably arranged inside the two adjustment boxes 31. A stroke baffle 33 is provided on the outer side of the two fork rods 101, and the outer sides of the two stroke baffles 33 are respectively connected to the two stroke adjustment plates 32 to limit the shock absorption stroke of the fork rods 101. After the fixed teeth 37 are separated from the tooth plate 34, the stroke adjustment plate 32 can be freely moved to perform fine-tuning according to personal preferences and road conditions. A tooth plate 34 is provided on the outer side of the left stroke adjustment plate 32.

[0025] The adjustment assembly 3 also includes a screw hole opened on the left side wall of the left adjustment box 31, and the inner wall of the screw hole is threadedly connected to an adjusting bolt 35. A push plate 36 is rotatably provided at the right end of the adjusting bolt 35, and a fixed tooth 37 engaged with the tooth plate 34 is provided on the right side of the push plate 36 to limit the position height of the stroke adjustment plate 32. Gently rotate the adjusting bolt 35 to move the push plate 36 outward to ensure that the engagement state between the fixed tooth 37 and the tooth plate 34 is released, preparing for the next adjustment.

[0026] In this embodiment, the upper sides of the two travel baffles 33 are provided with sliding holes for the fork rod 101 to slide, and a balance rod 38 is provided between the opposite sides of the two travel baffles 33 to make the two travel baffles 33 move synchronously. A handwheel is fixed to the left end of the adjusting bolt 35 to drive the adjusting bolt 35 to rotate. The upper and lower sides of the two adjustment boxes 31 are provided with adjustment ports for the sliding adjustment of the travel adjustment plates 32. By smoothly pulling the balance rod 38, the two travel baffles 33 are moved synchronously and slide along the outer side of the fork rod 101 to adjust the distance between the travel baffle 33 and the front fork sleeve 2, and the shock absorption stroke of the fork rod 101 is accurately set. According to the weight, riding style and expected road conditions, the travel baffle 33 is adjusted to the most suitable position to achieve the best shock absorption effect.

[0027] In this embodiment, limit plates are fixed at the upper and lower ends of the left stroke adjustment plate 32 to limit the stroke distance of the stroke adjustment plate 32, and sliding grooves 39 with the same length as the stroke adjustment plate 32 are provided on the front and rear sides of the right stroke adjustment plate 32.

[0028] In this embodiment, the front and rear inner walls of the right adjustment box 31 are respectively provided with sliders 310 that slide along the inner walls of the two slide grooves 39 to make the stroke adjustment plate 32 move vertically linearly. After adjusting to the ideal stroke, the adjusting bolt 35 is gradually tightened to push the push plate 36 inward, so that the fixed teeth 37 re-engage with the tooth plate 34 to ensure that the position of the stroke adjustment plate 32 remains fixed.

[0029] The working principle of the above embodiment is:

[0030] After the fixed teeth 37 are separated from the tooth plate 34, the travel adjustment plate 32 can be freely moved to make fine adjustments according to personal preferences and road conditions. By smoothly pulling the balance bar 38, the two travel baffles 33 are moved synchronously and slide along the outside of the fork rod 101 to adjust the distance between the travel baffle 33 and the front fork sleeve 2 to accurately set the shock absorption stroke of the fork rod 101. According to weight, riding style and expected road conditions, adjust the travel baffle 33 to the most suitable position to achieve the best shock absorption effect. After adjusting to the ideal stroke, gradually tighten the adjusting bolt 35 to push the push plate 36 inward to re-engage the fixed teeth 37 with the tooth plate 34 to ensure that the position of the travel adjustment plate 32 remains fixed.
