[0002] Currently, Chinese patent publication number CN213705648U discloses a novel motorcycle front fender structure, comprising a fender body, a decorative cover, and an inner bracket. The fender body has a mounting hole defined in the middle. The fender body and the decorative cover are bolted to the inner bracket, which is then mounted on the motorcycle's front shock absorber. The decorative cover comprises a top decorative cover and side decorative covers disposed on either side of the top decorative cover. The top decorative cover has slots defined on either side, and the side cover has buckles at the top that engage the slots. The inner bracket comprises an inner bracket body, a first bracket disposed on either side of the inner bracket body, and a second bracket disposed on either side of the inner bracket body. Both the first bracket and the second bracket have through-holes defined at their ends distal from the inner bracket body, and the first bracket has several mounting holes defined in the middle. However, the aforementioned front fender structure has a relatively large number of components, requiring a longer assembly time and resulting in relatively low assembly efficiency. Summary of the Invention

[0003] In view of this, an object of the present invention is to provide a motorcycle front fork assembly, which has the advantages of shorter assembly time and relatively higher assembly efficiency.

[0004] In order to solve the above technical problems, the technical solution of the present utility model is: a motorcycle front fork assembly, including a front fork shock absorbing structure, a front wheel and a front mud guard structure, the front fork shock absorbing structure including a front fork connecting pipe, a front fork connecting seat arranged at the lower end of the front fork connecting pipe, and two front fork shock absorbers arranged at the lower end of the front fork connecting seat, the two front fork shock absorbers are symmetrically distributed on the left and right sides, the front wheel is rotatably arranged at the lower ends of the two front fork shock absorbers, and a hydraulic disc brake is arranged on the side wall of the front wheel, the front mud guard structure includes a mud guard, and connecting brackets arranged on the left and right sides of the mud guard, the mud guard is arranged between the two front fork shock absorbers and is located above the front wheel, the left and right sides of the mud guard are both protruded outward to form a connecting cover, the lower end of the connecting bracket is pressed and fixed to the lower end of the front fork shock absorber by bolts, the upper end of the connecting bracket extends into the connecting cover, and the upper end of the connecting bracket is pressed and fixed to the inner wall of the connecting cover by bolts.

[0005] The above technical solution creates a front fender structure consisting of a fender plate and two connecting brackets. This structure is relatively simple, requiring minimal assembly time and offering the advantage of high assembly efficiency. The two connecting brackets are identical in shape, requiring only two molds to produce the front fender structure, significantly reducing the manufacturer's financial burden. The upper ends of the connecting brackets extend into the connecting cover, resulting in a simpler, more mechanically aesthetically pleasing appearance.

[0006] Preferably, a rubber connecting column is provided between the connecting cover and the connecting bracket, and a threaded section of a bolt for connecting the connecting cover and the connecting bracket passes through the rubber connecting column.

[0007] Through the above technical solution, the rubber connecting column can exert elastic force on the connecting cover and the connecting bracket after being compressed, so that the bolts connecting the connecting cover and the connecting bracket are not easy to loosen.

[0008] Preferably, a receiving groove is formed inwardly at a position where the connecting cover and the rubber connecting column are opposite to each other, and a head of a bolt connecting the connecting cover and the connecting bracket is received in the receiving groove.

[0009] Through the above technical solution, by providing a receiving groove for receiving the head of the bolt, the appearance of the above front mudguard structure is made simpler and more mechanically beautiful.

[0010] Preferably, a limiting bracket is provided on the outer side of the front fork shock absorber close to the hydraulic disc brake, and a limiting hole is provided on the limiting bracket for allowing an oil pipe connected to the hydraulic disc brake to pass through the limiting hole.

[0011] Through the above technical solution, the limiting bracket can be used to limit the oil pipe to prevent the oil pipe from being blocked by pressure, so as to ensure the normal operation of the hydraulic disc brake.

[0012] Preferably, the limiting bracket includes a fixed clamp, a movable buckle and a limiting screw. The fixed clamp is tightly clamped on the outside of the front fork shock absorber. A movable groove is provided at the side wall of the fixed clamp. The end of the movable buckle is inserted into the movable groove. The limiting hole is formed by the fixed clamp and the movable buckle. A threaded hole connected to the movable groove is provided at the upper end of the fixed clamp. The limiting screw is threadedly connected to the threaded hole, and the threaded section of the limiting screw is tightly pressed against the outer wall of the movable buckle.

[0013] Through the above technical solution, the limiting hole is formed by the fixed clamp and the movable buckle. In this way, it is only necessary to loosen the limiting screw to separate the threaded section of the limiting screw from the movable buckle, and then the fixed clamp and the movable buckle can be separated, making the disassembly and assembly of the oil pipe more convenient.

[0014] Preferably, two movable grooves are provided side by side, the movable buckle is U-shaped, and the two ends of the movable buckle are respectively inserted into the two movable grooves.

[0015] Through the above technical solution, the U-shaped movable buckle cooperates with the fixed clamp to more effectively limit the oil pipe. Furthermore, the U-shaped movable buckle and the fixed clamp have a larger contact area, making the connection more stable.

[0016] Preferably, a positioning ring groove is formed at the end of the movable buckle, and the threaded section of the limit screw extends into the positioning ring groove.

[0017] Through the above technical solution, the threaded section of the limit screw extends into the positioning ring groove, which can be used to more effectively limit the movable buckle.

[0018] Preferably, there are a plurality of positioning ring grooves, which are evenly spaced along the axial direction of the movable buckle.

[0019] With the above technical solution, by providing a plurality of positioning ring grooves, the aperture of the limiting hole can be changed to limit the oil pipes of different diameters. BRIEF DESCRIPTION OF THE DRAWINGS
