Description

Technical Field

[0001] This utility model relates to the field of motorcycle mudguard installation, specifically to an adjustable motorcycle mudguard installation structure. Background Technology

[0002] Motorcycle mudguards are protective components installed above the wheels. Their main functions include: blocking mud and water splashes, improving riding comfort and safety; protecting mechanical parts, reducing the impact and wear of mud, gravel, and other foreign objects on key components such as wheel hubs, brake systems, and chains; and optimizing aerodynamics, reducing wind resistance, and improving high-speed stability.

[0003] The distance between the mudguard and the wheel hub (usually referring to the vertical distance between the inner edge of the mudguard and the outer edge of the tire) directly affects its protective effect and vehicle safety. Currently, the distance between the mudguard and the wheel hub cannot be adjusted after installation. When riding on muddy or slippery roads, the tires kick up a large amount of mud and water. If the clearance between the mudguard and the rear wheel is too small, mud can easily clog the gap, affecting not only the mud-blocking effect but also potentially increasing mechanical friction loss between the wheel and the mud, and even causing a sharp increase in lift, affecting handling stability. Therefore, motorcycles used on such surfaces (such as off-road motorcycles) typically have a larger clearance between the mudguard and the rear wheel to prevent mud clogging and ensure mud-blocking effectiveness. When riding in urban areas or on dry roads, the amount of mud and water kicked up by the tires is relatively small. In this case, the clearance between the mudguard and the rear wheel can be designed to be smaller to ensure mud-blocking effectiveness while reducing the impact of air resistance on vehicle performance. Therefore, when riding in different road conditions, riders need to adjust the distance between the mudguard and the wheel hub according to their needs, but current technology does not allow for flexible adjustment based on these needs. In addition, after riding in mud for an extended period, mud can become trapped between the mudguard and the tire, hindering riding. Removing the mudguard or increasing the distance between it and the wheel rim would facilitate cleaning. However, existing mudguards have fixed installation positions and the distance between them and the wheel rim cannot be adjusted. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable motorcycle mudguard installation structure to solve the problem that the installation position of the motorcycle rear mudguard is fixed in the existing technology and cannot be adjusted in real time according to the rider's needs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An adjustable motorcycle mudguard mounting structure includes a rear swingarm and a rear mudguard. Support members are symmetrically mounted on the left and right sides of the rear mudguard, with their ends fixedly connected to the corresponding side rods of the rear swingarm. A rear wheel is mounted between the left and right side rods of the rear swingarm via a swingarm axle. Each support member includes two support rods. An upper connecting seat and a lower connecting seat are fixedly mounted on the upper and lower sides of the left and right side rods of the rear swingarm, respectively. The ends of the two support rods of the two support members correspond to the upper and lower connecting seats on their respective sides and can move laterally and be positioned on the upper and lower connecting seats. Thus, the support members are connected and fixed to the rear swingarm by fastening bolts and nuts, making installation and disassembly convenient. Furthermore, when the rider needs to adjust the distance between the rear mudguard and the rear wheel, they only need to first release the positioning of the support rods on the two support members from the upper and lower connecting seats, then move the two support rods and the rear mudguard together on the upper and lower connecting seats, and after moving into position, reconnect the support rods on the two support members to the upper and lower connecting seats.

[0006] Furthermore, both the upper and lower connecting seats have a horizontally oriented oblong hole. At the ends of the two support rods of the two support members, there is a mounting cylinder. A fastening bolt passes through the mounting cylinder and the corresponding oblong hole, and then engages with a fastening nut to secure the connection between the mounting cylinder and the upper connecting seat, and between the mounting cylinder and the lower connecting seat. Thus, when the rider needs to adjust the distance between the rear fender and the rear wheel, they only need to rotate the fastening nut and move the two support members and the rear fender together. During this movement, the fastening bolt can slide along the length of the oblong hole, thereby adjusting the installation position of the two support members. After adjustment, the fastening nut is rotated in the opposite direction to fix the support rods on the two support members to the upper and lower connecting seats. During adjustment, the oblong hole provides guidance for the sliding of the support members.

[0007] Furthermore, one side of the upper connecting seat is bent upwards to form an upper upright plate, and one side of the lower connecting seat is bent downwards to form a lower upright plate. The upper and lower upright plates are located on the same side, and an oblong hole is provided on the upper and lower upright plates. In this way, the upper and lower connecting seats are respectively provided with upper and lower upright plates. After the upper and lower upright plates are set, they can be easily attached to the mounting cylinder, and the structural strength of the upper and lower connecting seats is also high.

[0008] Furthermore, length graduations are marked on both the upper and lower upright plates along the length of the waist-shaped holes. These graduations at the waist-shaped holes provide an indication of the distance the rider travels, ensuring consistent movement of the support components on both sides for precise adjustment.

[0009] Furthermore, a retaining plate is provided on the upper connecting seat, opposite to the upper upright plate. The retaining plate is shorter than the upper upright plate and is located on one side of the waist-shaped hole. A rear shock absorber mounting groove is formed between the retaining plate and the upper upright plate. Mounting holes for fixing the rear shock absorber are provided on both the retaining plate and the upper upright plate. In this way, the retaining plate is shorter than the upper upright plate and located on one side of the waist-shaped hole, so it will not interfere with the installation of the support rod. At the same time, the retaining plate can also form a rear shock absorber mounting groove with the upper upright plate for installing the motorcycle rear shock absorber.

[0010] Furthermore, a mounting plate can be detachably installed on both the left and right sides of the rear fender. Each mounting plate has a slot (arc-shaped with an arc greater than a semicircle) on its opposite side for securing the two support rods. A pressure plate, pressing against the corresponding support rod, can also be detachably installed between the two support rods of the corresponding side support member in the middle of the two mounting plates. Two positioning plates are also detachably installed on the rear fender for securing and positioning the two support members respectively. In this way, the two support rods of the two support members are connected to the rear fender by a snap-fit ​​mechanism. Simultaneously, the positioning plates and pressure plates secure the connection, ensuring a stable structure that is unlikely to detach due to vibration during riding.

[0011] Furthermore, both sides of the mounting plate are bent inwards into a U-shape. This allows the two bent sections to conceal the ends of the support rods, resulting in a more aesthetically pleasing finish after installation.

[0012] Furthermore, a reinforcing plate is fixed between the two support rods of each support member. The upper and lower sides of the reinforcing plate are tightly attached to the corresponding support rods and fixed by welding. In this way, the two support rods are connected by a reinforcing plate, making the connection structure more stable and ensuring that the two support rods on the same side can move synchronously when moved.

[0016] During cycling, riders typically encounter various road conditions. For dry roads, lightweight competitive races, or short, temporary rides, the rear fender needs to be removed. For wet or muddy roads, a rear fender must be installed. Furthermore, the distance between the fender and the wheel hub needs to be adjusted depending on the conditions, whether riding on city streets or muddy or slippery rural or mountainous terrain. Therefore, a rear fender bracket is needed that allows for flexible adjustment of the distance between the rear fender and the rear wheel and is easy to install and remove.

[0017] like Figures 1-3 As shown, the adjustable motorcycle mudguard mounting structure provided in this embodiment includes a rear horizontal fork 1 and a rear mudguard 7. Support members 2 are symmetrically installed on the left and right sides of the rear mudguard 7, with their ends fixedly connected to the corresponding side rods 11 of the rear horizontal fork 1. A rear wheel 7 is installed between the left and right side rods 11 of the rear horizontal fork 1 through a horizontal fork shaft. The support member 2 includes two support rods 21. An upper connecting seat 3 and a lower connecting seat 4 are fixedly installed on the upper and lower sides of the left and right side rods 11 of the rear horizontal fork 1, respectively. The ends of the two support rods 21 of the two support members 2 correspond to the upper connecting seat 3 and the lower connecting seat 4 on the corresponding sides, and can move laterally and be positioned on the upper connecting seat 3 and the lower connecting seat 4. In this embodiment, the movement and installation of the two support members 2 are achieved through the following structure: A horizontally arranged waist-shaped hole (not shown in the figure) is provided on both the upper connecting seat 3 and the lower connecting seat 4. An installation cylinder 23 is provided at the end of each of the two support rods 21 of the two support members 2. A fastening bolt 5 passes through the installation cylinder 23 and the corresponding side waist-shaped hole, and is then threadedly engaged with a fastening nut 6 to secure the connection between the installation cylinder 23 and the upper connecting seat 3, and between the installation cylinder 23 and the lower connecting seat 4. (Specifically, a washer is provided on the side of the fastening nut 6 near the side rod 11, and the washer is fitted onto the fastening bolt 5.) Thus, the support member 2 and the rear horizontal fork 1 are connected and fixed by the fastening bolt 5 and the fastening nut 6, making installation and disassembly relatively convenient. Simultaneously, when the rider needs to adjust the distance between the rear fender and the rear wheel 7, simply release the positioning between the support rods 21 on the two support members 2 and the upper connecting seat 3 and lower connecting seat 4. Then, move the two support rods 21 and the rear fender 7 together on the upper connecting seat 3 and lower connecting seat 4. After moving into position, reconnect the support rods 21 on the two support members 2 to the upper connecting seat 3 and lower connecting seat 4. When the rider needs to adjust the distance between the rear fender and the rear wheel 7, simply rotate the fastening nut 6 and move the two support members 2 and the rear fender 7 together. During the movement, the fastening bolt 5 can slide along the length of the oblong hole, thereby adjusting the installation position of the two support members 2. After adjustment, rotate the fastening nut 6 in the opposite direction to fix the support rods 21 on the two support members 2 to the upper connecting seat 3 and lower connecting seat 4. During adjustment, the oblong hole can guide the sliding of the support member 2.

[0018] Of course, in practical implementation, the aforementioned fastening bolt 5 can be welded and fixed to the two support rods 21 of the support member 2. Alternatively, a T-shaped slider can be used instead of the fastening bolt 5. During adjustment, pushing the support rod 21 moves the slider, and after sliding to the expected position, the slider is positioned by the locking device. When disassembly is required, the locking device can be removed directly, and the slider can be rotated so that its end corresponds to the oblong hole, and then removed from the oblong hole.

[0019] Furthermore, one side of the upper connecting seat 3 is bent upward to form an upper upright plate 31, and one side of the lower connecting seat 4 is bent downward to form a lower upright plate 41. The upper upright plate 31 and the lower upright plate 41 are located on the same side, and an oblong hole is provided on the upper upright plate 31 and the lower upright plate 41. In this way, the upper connecting seat 3 and the lower connecting seat 4 are respectively provided with an upper upright plate 31 and a lower upright plate 41. After the upper upright plate 31 and the lower upright plate 41 are set, they can be easily attached to the mounting cylinder 23, and the structural strength of the upper connecting seat 3 and the lower connecting seat 4 is also high.

[0020] Furthermore, length scale lines (not shown in the figure) are marked on both the upper upright plate 31 and the lower upright plate 41 along the length of the waist-shaped hole, and the scale markings and starting positions of each length scale line are consistent. In this way, after setting the length scale lines at the waist-shaped hole, it can provide an indication of the distance the rider moves, ensuring that the moving distance of the two side support members 2 is consistent, so as to achieve the purpose of precise adjustment.

[0021] Furthermore, a retaining plate 32 is provided on the upper connecting seat 3, on the opposite side of the upper upright plate 31. The length of the retaining plate 32 is less than the length of the upper upright plate 31, and it is located on one side of the waist-shaped hole. A rear shock absorber mounting groove is formed between the retaining plate 32 and the upper upright plate 31. Mounting holes for fixing the rear shock absorber are provided on both the retaining plate 32 and the upper upright plate 31. In this way, the retaining plate 32 is shorter than the upper upright plate 31 and is located on one side of the waist-shaped hole, so it will not interfere with the installation of the support rod 21. At the same time, the retaining plate 32 can also form a rear shock absorber mounting groove with the upper upright plate 31 for installing the motorcycle rear shock absorber.

[0022] like Figure 2 , Figure 4As shown, a mounting plate 71 can be detachably installed on both the left and right sides of the rear fender 7. Each mounting plate 71 has a slot on its opposite side for securing the two support rods 21 (the slot is arc-shaped with an arc greater than a semicircle). A pressure plate 74 can also be detachably installed between the two support rods 21 of the corresponding side support member 2 at the center of the two mounting plates 71. This pressure plate 74 (with a threaded post inside the rear fender, the pressure plate 74 is connected to the threaded post by a screw 73 passing through it) is also detachably installed on the rear fender 7. Two positioning plates 72 are also detachably installed on the rear fender 7 for securing and positioning the two support members 2 respectively. The positioning plates 72 are bent downwards on both sides and then horizontally, and are locked and fixed to the rear fender by fasteners. In this way, the two support rods of the two support members are connected to the rear fender by a locking mechanism. Simultaneously, the positioning plates and pressure plates secure the connection, making the structure stable and preventing it from easily falling off due to vibration during riding.

[0023] Furthermore, both sides of the mounting plate 71 are bent inwards to form a U-shape. In this way, the two bent parts can cover the ends of the support rod 21, making the installation more aesthetically pleasing.

[0024] In this embodiment, the distance between the two support rods 21 of each support member 2 gradually decreases from the connecting end of the rear horizontal fork 1 to the connecting end of the rear mudguard 7. A reinforcing plate 22 is also fixed between the two support rods 21 of each support member 2. The upper and lower sides of the reinforcing plate 22 are tightly attached to the corresponding side support rods 21 and fixed by welding. A weight-reducing hole is also provided in the middle of the reinforcing plate 22 to reduce the weight of the entire support member 2. In this way, the two support rods 21 are connected by a reinforcing plate 22, the connection structure is more stable, and it can be ensured that the two support rods 21 on the same side can move synchronously when moving.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
