Technical Field

[0001] This utility model relates to the field of rear mudguard technology, and in particular to an adjustable rear mudguard assembly. Background Technology

[0002] Currently, motorcycles and other vehicles widely use rear mudguards to shield themselves from mud, water, or dust, improving rider comfort and the vehicle's appearance.

[0003] Common rear fenders employ a two-section support arm design, with angle adjustment achieved via tightening and loosening bolts. This method is simple to operate and suitable for various installation needs. However, this design has certain limitations when adapting to similar vehicle models and specific installation requirements. The main problem is that adjusting the distance between the rear fender and the tire requires replacing the support arm with one of different lengths. This not only increases production and storage costs but also makes it inconvenient for users to adjust flexibly according to their actual needs. This adjustment method, which relies on changing the length of the support arm, lacks flexibility and cannot meet the specific usage needs of all users. Therefore, we propose an adjustable rear fender assembly. Utility Model Content

[0007] Furthermore, the three-section design of the adjustment groove includes a wide-mouth slide groove, a narrow-mouth slide groove, and a nut fixing groove. The width of the narrow-mouth slide groove is smaller than that of the wide-mouth slide groove and the nut fixing groove, and the width of the nut fixing groove is larger than that of the locking nut. The wide-mouth slide groove, the narrow-mouth slide groove, and the nut fixing groove are opened through the angle adjustment arm from one end face to the other end face along the length direction.

[0008] Furthermore, the cross-section of the adjusting block is convex, and the two ends of the adjusting block are provided with sliders. The sliders are slidably connected in the limiting groove opened along the length direction of the wide-mouth groove. The size of the adjusting block is adapted to the wide-mouth groove and the narrow-mouth groove.

[0009] Furthermore, the adjusting block is bolted or welded to the connecting arm, and the connecting arm is bolted or welded to the rear mudguard.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Example 1

[0032] like Figure 1-4As shown, this utility model provides a technical solution: an adjustable rear mudguard assembly, including a mounting and fixing arm 1, an angle adjusting arm 2, and a rear mudguard 3. The angle adjusting arm 2 and the mounting and fixing arm 1 are rotatably connected by a rotating connection structure (such as a bolt rod passing through the mounting and fixing arm 1, and the angle adjusting arm 2 rotating on the bolt rod), and are pressed and fixed by bolts. This design ensures that the two can rotate relative to each other to achieve angle adjustment, and can be firmly fixed by bolts after adjusting to a suitable angle.

[0033] An adjustment groove 4 is provided on the angle adjustment arm 2. The adjustment groove 4 provides a track for the sliding of the subsequent adjustment block 5. The adjustment block 5 is slidably connected in the adjustment groove 4 and can slide in the adjustment groove 4 according to a preset trajectory. The end of the adjustment block 5 away from the mounting and fixing arm 1 is fixedly connected to the rear mudguard 3 through the connecting arm 6. The connecting arm 6 serves to connect the adjustment block 5 and the rear mudguard 3, so that the movement of the adjustment block 5 can drive the movement of the rear mudguard 3. A threaded fixing head 7 is provided on the outer side of the other side of the adjustment block 5. A locking nut 8 is threadedly connected to the threaded fixing head 7. Rotating the locking nut 8 in both directions will cause the adjustment block 5 to be squeezed and fixed when it rotates towards the adjustment groove 4 and abuts against the adjustment groove 4, thereby fixing the position of the adjustment block 5. When the locking nut 8 rotates away from the adjustment groove 4, it will release the fixing of the adjustment block 5, allowing the adjustment block 5 to slide freely in the adjustment groove 4, thus realizing the fixing and unlocking of the position of the adjustment block 5.

[0034] Example 2

[0035] like Figure 1-4 As shown, the adjustment groove 4 adopts a three-section design, including a wide-mouth slide groove 41, a narrow-mouth slide groove 42, and a nut fixing groove 43. The width of the narrow-mouth slide groove 42 is smaller than that of the wide-mouth slide groove 41 and the nut fixing groove 43, and the width of the nut fixing groove 43 is larger than that of the locking nut 8, providing sufficient space for the locking nut 8 to rotate and fix. The wide-mouth slide groove 41, the narrow-mouth slide groove 42, and the nut fixing groove 43 are opened through the angle adjustment arm 2 from one end face to the other end face along the length direction, ensuring that the adjustment block 5 can slide and adjust within the entire length range of the angle adjustment arm 2.

[0036] The cross-section of the adjusting block 5 is convex, which allows the adjusting block 5 to better fit with the adjusting groove 4. The two ends of the adjusting block 5 are provided with sliders 51, which are slidably connected in the limiting groove 44 opened along the length direction of the wide groove 41. The limiting groove 44 limits the slider 51, preventing the adjusting block 5 from shifting during the sliding process, ensuring the stability and accuracy of the sliding of the adjusting block 5, and providing a limiting contact surface to cooperate with the locking nut 8 to fix the position of the sliding block. The size of the adjusting block 5 is adapted to the wide groove 41 and the narrow groove 42, so that the adjusting block 5 can slide smoothly in the adjusting groove 4 without shaking or jamming.

[0037] The adjusting block 5 and the connecting arm 6 can be fixed by bolts or by welding. Bolting makes it easier to disassemble and replace, while welding is more robust and stable. Similarly, the connecting arm 6 and the rear mudguard 3 can also be fixed by bolts or by welding. Users can choose the appropriate connection method according to their actual needs and usage scenarios.

[0038] The threaded fixing head 7 is welded to the adjusting block 5 and extends into the nut fixing groove 43, providing an installation position for the locking nut 8. There are no fewer than two threaded fixing heads 7. Multiple threaded fixing heads 7 can distribute the fixing force and enhance the stability of the fixing. An anti-loosening washer is provided between the locking nut 8 and the inner wall of the nut fixing groove 43. The anti-loosening washer can increase the friction between the locking nut 8 and the nut fixing groove 43, preventing the locking nut 8 from loosening due to vibration or other reasons during vehicle operation, thereby ensuring the stability of the position of the adjusting block 5.

[0039] The mounting arm 1 has an open end away from the angle adjustment arm 2. This design facilitates insertion and connection with the motorcycle mounting part, improving installation stability. Bolt mounting holes 11 are provided at both ends of the open end, corresponding to the preset holes in the motorcycle mounting part. By passing bolts through the bolt mounting holes 11 and the preset holes in the motorcycle mounting part, the mounting arm 1 can be firmly installed on the motorcycle. A weight reduction groove 12 is provided through the mounting arm 1. The weight reduction groove 12 can reduce the weight of the entire rear fender assembly while ensuring the structural strength of the mounting arm 1.

[0040] The working process of this utility model is as follows: When using an adjustable rear fender assembly, firstly, the open end of the mounting arm 1 is engaged with the motorcycle mounting part, so that the bolt mounting hole 11 on the mounting arm 1 is aligned with the preset hole position of the motorcycle mounting part. Then, bolts are passed through the bolt mounting hole 11 and the preset hole position, and the mounting arm 1 is firmly installed on the motorcycle by means of bolts.

[0041] Next, adjust the distance between the rear fender 3 and the tire according to actual needs. First, turn the locking nut 8 counterclockwise to move the locking nut 8 away from the adjustment groove 4 and release the fixing of the adjustment block 5. At this time, the adjustment block 5 can slide freely in the adjustment groove 4. By pushing the adjustment block 5, the adjustment block 5 drives the connecting arm 6 and the rear fender 3 to move together, thereby changing the distance between the rear fender 3 and the tire. During the adjustment process, the sliders 51 at both ends of the adjustment block 5 slide in the limiting groove 44 of the wide-mouth groove 41 to ensure the stability of the sliding of the adjustment block 5.

[0042] After adjusting to the appropriate spacing, rotate the locking nut 8 clockwise to move the locking nut 8 towards the adjusting groove 4 and abut against the adjusting groove 4. The slider 51 abuts against the limiting groove 44, which exerts a squeezing and fixing effect on the adjusting block 5, fixing the adjusting block 5 in the current position. Since the number of threaded fixing heads 7 is not less than two and anti-loosening washers are provided, it can be ensured that the locking nut 8 is firmly fixed and will not loosen during vehicle operation.

[0043] The angle of the adjustable support arm 2 can be finely adjusted by rotating the connecting bolt between the angle adjustment support arm 2 and the mounting support arm 1. After adjusting to the appropriate angle, the connecting bolt is tightened again to fix the angle adjustment support arm 2 and the mounting support arm 1 at the current angle, thus completing the installation and adjustment process of the entire adjustable rear fender assembly and making it better meet the riding needs.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
