Description

Technical Field

[0001] This invention relates to the field of motorcycle front fender technology, and in particular to a motorcycle front fender bracket. Background Technology

[0002] The motorcycle front fender is a key protective component mounted above the front wheel of a motorcycle. Its core function is to block mud, sand, and debris splashed from the front wheel during vehicle operation, preventing debris from hitting the vehicle body or splashing onto the rider. At the same time, it can reduce the corrosion of the vehicle's core components by mud and water, thus protecting the vehicle and improving riding comfort and safety.

[0003] The motorcycle front fender bracket is a special support structure that connects the front fender to the motorcycle frame. As a load-bearing and connecting intermediary between the fender and the frame, it must provide a stable mounting base for the front fender to ensure that the position of the fender is fixed during vehicle operation. It must also be compatible with the assembly dimensions of the fender and the frame to ensure that the fender corresponds to the protective area above the front wheel.

[0004] Most existing motorcycle front fender brackets adopt an integrated welded structure. This type of bracket is rigidly connected to the frame by a welded connecting plate, and the fender is then locked in place at the pre-set mounting point of the bracket with bolts. This prevents the fender from shaking or falling off when the vehicle is in motion. However, because the mounting point is fixed, the mounting height of the fender cannot be changed by adjusting the bracket itself during actual use. This makes it impossible to adjust the distance between the fender and the wheel, making it difficult to adapt to different sizes of front wheels or meet the rider's personalized needs for protection height. Summary of the Invention

[0005] The purpose of this invention is to provide a motorcycle front mudguard bracket that solves the problem that a fixed mudguard height cannot be adapted to front wheels of different sizes or meet the rider's personalized needs for protection height.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a motorcycle front mudguard bracket, including a mudguard frame, an installation mechanism provided in the middle of the mudguard frame, a fixing mechanism provided at the bottom of the mudguard frame, and a support mechanism provided on the inner side of the mudguard frame, the support mechanism being used to provide shock absorption support for the exterior of the mudguard frame; The installation mechanism includes two crossbars, both of which are slidably connected to the middle of the mud board frame. Each crossbar has a threaded groove at both ends, and a threaded ring I is threadedly connected to both sides of each crossbar. The opposite side of the two threaded rings I is in contact with the inner wall of the mud board frame. Each crossbar also has a threaded ring II threadedly connected to both ends, and a rotating ring is rotatably connected to the outer wall of each of the two threaded rings. A fixing block I is fixedly connected to both sides of each of the two rotating rings. A lifting bracket is slidably connected to the middle of each fixing block I. A threaded column is fixedly connected to the top of the lifting bracket, and an installation plate is fitted onto the outer wall of the threaded column. A fixing ring II is rotatably connected to the outer wall of the threaded column. A positioning component is provided on the outer wall of the lifting bracket. Through the above technical solution: the installation mechanism realizes the installation and position adjustment of the mudguard. Two crossbars slidably connected in the middle of the mudguard frame serve as the core support base. The threaded grooves at both ends of the crossbars can form a threaded engagement with threaded ring one and threaded ring two. Threaded ring one fits against the inner wall of the mudguard frame to lock and fix the position of the crossbars. Threaded ring two can drive the rotating ring on its outer wall to move left and right to adapt to mudguards of different widths. Fixed blocks one on both sides of the rotating ring provide sliding support for the lifting bracket. The lifting bracket can drive the mudguard to adjust the distance between itself and the wheel. The threaded post at the top is used to fit the mounting plate to connect with the mudguard. Fixed ring two can limit and fix the position of the mounting plate. The positioning component on the outer wall of the lifting bracket can lock the sliding position of the lifting bracket, ensuring the stability of the mudguard after installation.

[0007] Preferably, the fixing mechanism includes two horizontal plates, which are arranged on both sides of the mud board frame. A fixing plate is fixedly connected to one side of each horizontal plate. A connecting plate is rotatably connected to the front side of the fixing plate. An installation ring is rotatably connected to the other side of the connecting plate. A moving groove is provided on the other side of the fixing plate. A threaded rod is rotatably connected to the rear side of the fixing plate. The front end of the threaded rod passes through the moving groove and is threadedly connected to a connecting plate. An installation ring is fixedly connected to the other side of the connecting plate. A fixing block is fixedly connected to the other side of both the first and second installation rings. A fixing bolt is rotatably connected to the rear side of the fixing block. The front end of the fixing bolt passes through the fixing block. A reinforcing component is provided on the other side of the horizontal plate. Through the above technical solution: the fixing mechanism achieves a stable assembly of the mudguard frame and the motorcycle through the cooperation of multiple components. Two horizontal plates set on both sides of the mudguard frame serve as the installation base, and the fixing plate on one side provides a carrier for each connecting component. The connecting plate one on the front side of the fixing plate can drive the mounting ring one to adjust its angle to align with the motorcycle's front bumper. The threaded rod on the rear side of the fixing plate passes through the moving groove and is threadedly engaged with the connecting plate two, which can drive the connecting plate two to move the mounting ring two, together with the mounting ring one to clamp the motorcycle's front bumper. The fixing block two on the mounting ring one and the mounting ring two can bear the fixing bolt. The fixing bolt passes through the fixing block two to lock and fix the two mounting rings. The reinforcing component on the other side of the horizontal plate further enhances the connection strength between the fixing mechanism and the mudguard frame, ensuring that the overall assembly structure is firm and reliable.

[0008] Preferably, the support mechanism includes a first fixed ring, which is fixedly connected to the outer wall of the crossbar. Return springs are fixedly connected to both sides of the first fixed ring. Moving rings are fixedly connected to the opposite ends of the two return springs. Connecting blocks are fixedly connected to the bottom of each of the two moving rings. Rotating plates are rotatably connected to the bottom of each of the two connecting blocks. Connecting blocks are rotatably connected to the bottom of each of the two rotating plates. The other side of each of the two connecting blocks is fixedly connected to the inner wall of the mud board frame. A guide assembly is provided inside the moving ring. Through the above technical solution: the support mechanism achieves shock absorption and stable support for the mud slab frame through multi-component linkage. The fixed ring 1, which is fixedly connected to the outer wall of the crossbar, serves as the core support base point. The return springs on both sides can absorb external extrusion pressure through their own expansion and contraction deformation. The moving ring at the end of the return spring can drive the connecting block 1 at the bottom to move synchronously. The connecting block 1 rotates and cooperates with the rotating plate, which can transmit the force generated by the extrusion of the mud slab frame to the return spring. The connecting block 2 at the bottom of the rotating plate connects the support mechanism to the inner wall of the mud slab frame, effectively transmitting the extrusion pressure. The guide component inside the moving ring can limit the movement trajectory of the moving ring, preventing it from rotating and deviating on the outer wall of the crossbar, thus ensuring the stable operation of the support mechanism.

[0009] Preferably, the positioning component includes multiple positioning teeth, which are fixedly connected to both sides of the lifting bracket. A rotating rod is rotatably connected to one side of the fixing block, and the rotating rod passes through the fixing block and is rotatably connected to a positioning tooth. Through the above technical solution: the positioning component locks the position of the lifting bracket by the engagement of each component. The multiple positioning teeth are fixed on both sides of the lifting bracket and can serve as the basic structure for positioning engagement. The rotating rod connected to one side of the fixed block can drive the positioning teeth through the fixed block to move. By controlling the rotation of the rotating rod, the positioning teeth can engage or disengage with the positioning teeth, thereby locking and unlocking the sliding position of the lifting bracket.

[0010] Preferably, the reinforcing component includes a cylinder with a sliding groove inside. Two pushing blocks are slidably connected inside the sliding groove. A rotating rod is rotatably connected to the outside of the cylinder. The rotating rod passes through the cylinder and is rotatably connected to a pressing block. Through the above technical solution: the reinforcement component achieves tight fit and reinforcement with the mudplate frame through component linkage. The cylinder serves as the core mounting base, and the sliding groove inside provides sliding space for the two push blocks. The rotating rod rotatably connected to the outside of the cylinder can drive the extrusion block that passes through the cylinder to move. The extrusion block drives the push block in the sliding groove to expand outward through the extrusion action, so that the push block fits tightly with the inner wall of the mudplate frame, thereby enhancing the connection between the fixing mechanism and the mudplate frame and preventing loosening after assembly.

[0011] Preferably, sliders are fixedly connected to both sides of the push block, and a groove is provided inside the cylinder, with the sliders slidably connected to the middle of the groove; Through the above technical solution: the sliders fixedly connected to both sides of the push block slide in cooperation with the grooves opened inside the cylinder, which precisely limits the sliding direction of the push block, prevents the push block from tilting, jamming or deviating during the sliding process, and ensures that the push block can expand outward stably along the preset trajectory and fit tightly against the inner wall of the mud board frame, thus ensuring that the reinforcement effect of the reinforcement component is stable and reliable.

[0012] Preferably, a guide rod is fixedly connected to the inner wall of the movable groove, and the guide rod passes through one side of the connecting plate two; Through the above technical solution: the guide rod fixedly connected to the inner wall of the moving groove passes through one side of the connecting plate two, which can guide the moving trajectory of the connecting plate two in the moving groove, effectively restricting the deviation or shaking of the connecting plate two when it moves, ensuring that it can smoothly drive the installation ring two to move, and ensuring the clamping and fixing effect of the fixing mechanism.

[0013] Preferably, sliders are fixedly connected to both sides of the push block, and a groove is provided inside the cylinder, with the sliders slidably connected to the middle of the groove; Through the above technical solution: the sliders fixed on both sides of the push block slide in cooperation with the grooves opened inside the cylinder, which can limit the sliding direction of the push block, prevent it from tilting or deviating when moving, and ensure that the push block expands outward stably along the preset trajectory.

[0014] Preferably, washers are fitted at both ends of the crossbar, and one side of the washers is in contact with the threaded ring; Through the above technical solution: the gaskets fitted at both ends of the crossbar fit against the threaded ring, which can increase the contact area between the threaded ring and the inner wall of the mud plate frame, improve the fixing stability of the threaded ring pair against the crossbar, and at the same time play a buffering and protective role, avoiding direct contact of the threaded ring and causing wear.

[0015] Preferably, the two sides of the extrusion block are in contact with one side of the push block, and both the extrusion block and one side of the push block are designed to be inclined. Through the above technical solution: the two sides of the extrusion block are attached to one side of the push block, and both sides are inclined. This can efficiently convert the lateral thrust of the extrusion block into the outward expansion force of the push block, ensuring that the push block moves outward quickly and fits tightly against the inner wall of the mud board frame, thereby improving the reinforcement efficiency and effect of the reinforcement component.

[0016] In summary, the present invention has at least one of the following beneficial technical effects: 1. This invention achieves adjustable mudguard installation position, strong adaptability, and stable positioning after spacing adjustment by rotating threaded ring one to fix the crossbar, rotating threaded ring two to adjust the position of the rotating ring to adapt to mudguards of different widths, rotating mounting plate to adjust the installation position and being limited by fixed ring two, rotating rotating rod one to disengage or engage positioning tooth two with positioning tooth one, and pulling and raising bracket to adjust the distance between mudguard and wheel.

[0017] 2. This invention achieves a stable assembly of the mudguard frame and the motorcycle by inserting a cylinder into the mudguard frame, rotating a rotating rod to push the extrusion block to move, and extrusion pushing the block to fit outward against the inner wall of the mudguard frame. Then, the connecting plate is rotated to install the first mounting ring, and the threaded rod is rotated to drive the second mounting ring to move, clamping the front bumper with the first mounting ring and locking it with a fixing bolt. This results in a high connection strength, simple installation process, and good adaptability.

[0018] 3. This invention uses the mudguard being squeezed to cause the mudguard frame to contract inward, which pushes the connecting block two to move the rotating plate towards the center. This, in turn, pushes the connecting block one and the moving ring to squeeze the reset springs on both sides of the fixed ring one to absorb the pressure. At the same time, the guide block slides in the guide groove to prevent the moving ring from rotating, thus achieving efficient shock absorption and buffering of the mudguard frame, improving support stability, and avoiding damage to components due to compression.

[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 The present invention will be further described in detail below.

[0022] The present invention provides a motorcycle front mudguard bracket, which can be adapted to mudguards of different widths by setting a mounting mechanism 2 and can adjust the distance between the mudguard and the wheel.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This invention provides a motorcycle front fender bracket, including a fender frame 1. An installation mechanism 2 is provided in the middle of the fender frame 1 to realize the function of bearing and installing the front fender of the motorcycle. A fixing mechanism 3 is provided at the bottom of the fender frame 1 to securely assemble the entire bracket to the motorcycle body. A support mechanism 4 is provided on the inner side of the fender frame 1 to provide shock absorption support for the outside of the fender frame 1. The mounting mechanism 2 includes two crossbars 21, which provide the mounting base for each component of the mounting mechanism 2. Both crossbars 21 are slidably connected to the middle of the clay plate frame 1, enabling adjustment of the mounting position of the crossbars 21 on the clay plate frame 1. Both ends of the crossbars 21 are provided with threaded grooves 22, enabling threaded engagement with threaded rings 23 and 24. Both sides of the crossbars 21 are threadedly connected to threaded rings 23, enabling locking and fixing of the crossbars 21 on the clay plate frame 1. The opposite sides of the two threaded rings 23 are in contact with the inner wall of the clay plate frame 1, increasing the contact area between the threaded rings 23 and the clay plate frame 1 and improving the fixing stability. Both ends of the crossbars 21 are threadedly connected to threaded rings 24, enabling adjustment of the left and right positions by driving the rotating ring 25. The outer walls of the two threaded rings 24 are rotatably connected to rotating rings. 25, which provides a mounting carrier for the first fixed block 26. The two rotating rings 25 are fixedly connected to the first fixed block 26 on both sides, which provides a sliding support for the lifting bracket 27. The middle of the first fixed block 26 is slidably connected to the lifting bracket 27, which drives the mudguard to adjust the distance between the mudguard and the wheel. The top of the lifting bracket 27 is fixedly connected to the threaded column 28, which provides a mounting fit structure for the mounting plate 210 and the second fixed ring 211. The outer wall of the threaded column 28 is fitted with the mounting plate 210, which allows it to be installed with the front mudguard of the motorcycle. The outer wall of the threaded column 28 is rotatably connected to the second fixed ring 211, which limits and locks the position of the mounting plate 210 on the threaded column 28. The outer wall of the lifting bracket 27 is provided with a positioning component 29, which locks the sliding position of the lifting bracket 27. The positioning component 29 includes multiple positioning teeth 291, which can engage with positioning teeth 293. The multiple positioning teeth 291 are fixedly connected to both sides of the lifting bracket 27, which can provide a locking and positioning structure for the positioning component 29. A rotating rod 292 is rotatably connected to one side of the fixing block 26, which can drive the positioning teeth 293 to move. The rotating rod 292 passes through the fixing block 26 and is rotatably connected to the positioning teeth 293, which can engage or disengage with the positioning teeth 291 to control the limiting state of the lifting bracket 27. Specifically, the installation mechanism 2 uses two crossbars 21 slidably connected to the middle of the mudguard frame 1 as a basic support. First, the threaded rings 23 on both sides of the crossbar 21 are rotated to move it to both ends and fit against the inner wall of the mudguard frame 1, thereby fixing the crossbar 21 on the mudguard frame 1. Then, the left and right positions of the outer wall rotating ring 25 are adjusted by rotating the threaded rings 24 connected to the two ends of the crossbar 21 to adapt to the installation requirements of motorcycle front mudguards of different widths. At the same time, the lifting brackets 27 slidably connected to the fixing blocks 26 on both sides of the rotating ring 25 are used to adjust the installation angle and position by rotating the mounting plate 210 fitted on the threaded post 28 at the top of the lifting bracket 27. The fixing rings 211 on the outer wall of the threaded post 28 are used to fix the installation. The mounting plate 210 is used for limiting and fixing to ensure the stability of the mudguard installation. When it is necessary to adjust the distance between the mudguard and the wheel, the rotating rod 292 on one side of the fixing block 26 can be rotated to drive the positioning tooth 293 through the fixing block 26 to move outward, so that it disengages from the positioning tooth 291 on both sides of the lifting bracket 27, releasing the limitation on the lifting bracket 27. At this time, pulling the lifting bracket 27 upward will drive the mudguard to rise synchronously to increase the distance between it and the wheel. After moving to the target position, the rotating rod 292 is rotated in the opposite direction to push the positioning tooth 293 to move inward and re-engage with the positioning tooth 291, completing the limiting and fixing of the lifting bracket 27 and ensuring the stability of the mudguard position after the distance is adjusted.

[0024] Reference Figure 2 , Figure 5 , Figure 6 and Figure 7The fixing mechanism 3 includes two horizontal plates 31, which are arranged on both sides of the mudguard frame 1. These plates connect and assemble the fixing mechanism 3 to the mudguard frame 1. A fixing plate 32 is fixedly connected to one side of each horizontal plate 31, providing a mounting carrier for the connecting plate 33 and the threaded rod 36. The front side of the fixing plate 32 is rotatably connected to the connecting plate 33, allowing the mounting ring 34 to be adjusted at the mounting angle. The other side of the connecting plate 33 is rotatably connected to the mounting ring 34, enabling initial docking with the motorcycle front bumper. A movable groove 35 is provided on the other side of the fixing plate 32, providing guiding space for the movement of the connecting plate 37. The rear side of the fixing plate 32 is rotatably connected to the threaded rod 36, allowing the connecting plate 37 to be adjusted in position by rotation. The front end of the threaded rod 36 passes through... A connecting plate 37 is threaded through the moving slot 35, enabling the second mounting ring 38 to move towards the first mounting ring 34. The other side of the connecting plate 37 is fixedly connected to the second mounting ring 38, which works with the first mounting ring 34 to clamp the front bumper of the motorcycle. The other side of both the first mounting ring 34 and the second mounting ring 38 is fixedly connected to a fixing block 310, providing an installation position for the fixing bolt 311. The rear side of the fixing block 310 is rotatably connected to the fixing bolt 311, locking the first mounting ring 34 and the second mounting ring 38 together. The front end of the fixing bolt 311 passes through the fixing block 310, completing the locking engagement. A reinforcing component 39 is provided on the other side of the horizontal plate 31, enhancing the connection between the fixing mechanism 3 and the mudguard frame 1. The reinforcement component 39 includes a cylinder 391, which provides a mounting base for each component of the reinforcement component 39. The cylinder 391 has a sliding groove 392 inside, which provides a space for the sliding of the push block 395. Two push blocks 395 are slidably connected inside the sliding groove 392, which expands outward and fits against the inner wall of the mud plate frame 1. A rotating rod 393 is rotatably connected to the outside of the cylinder 391, which drives the extrusion block 394 to move in position. The rotating rod 393 passes through the cylinder 391 and is rotatably connected to the extrusion block 394, which transmits the force of the rotating rod 393 to the push block 395. Specifically, the fixing mechanism 3, with the fixing plate 32 on one side of the horizontal plate 31, achieves a dual fixing function. Firstly, the connecting plate 33, rotatably connected to the front of the fixing plate 32, drives the mounting ring 34 to adjust its angle to fit the installation position of the motorcycle front bumper. Simultaneously, rotating the threaded rod 36 on the rear of the fixing plate 32 causes the connecting plate 37 and the mounting ring 38, which pass through the moving groove 35 of the fixing plate 32, to move towards the mounting ring 34. This allows the mounting ring 34 and the mounting ring 38 to clamp the motorcycle front bumper. Then, through the other... The fixing bolts 311 on the side fixing block 310 are locked and fixed to complete the stable connection between the mudguard frame 1 and the front bumper of the motorcycle. Secondly, the installation strength is improved by the reinforcement component 39 on the other side of the horizontal plate 31. After the cylinder 391 is inserted into the mudguard frame 1, the rotating rod 393 on the outside of the cylinder 391 is rotated to drive the extrusion block 394 through the cylinder 391 to move, thereby extruding the two pushing blocks 395 in the sliding groove 392 to move outward and fit tightly against the inner wall of the mudguard frame 1, thereby enhancing the connection stability between the fixing mechanism 3 and the mudguard frame 1.

[0025] Reference Figure 1 and Figure 8 The support mechanism 4 includes a fixed ring 41, which provides an installation position for the return spring 42. The fixed ring 41 is fixedly connected to the outer wall of the crossbar 21. Return springs 42 are fixedly connected to both sides of the fixed ring 41, realizing the function of absorbing external pressure through their own expansion and contraction. Moving rings 43 are fixedly connected to the far ends of the two return springs 42, realizing the function of driving the connecting block 44 to move synchronously. Connecting blocks 44 are fixedly connected to the bottom of the two moving rings 43, realizing the function of providing a rotational connection fulcrum for the rotating plate 45. The bottom of each of the two connecting blocks 44 is rotatably connected to a rotating plate 45, which realizes the function of transmitting the extrusion force of the mud plate frame 1 to the return spring 42. The bottom of each of the two rotating plates 45 is rotatably connected to a connecting block 46, which realizes the function of connecting the rotating plate 45 to the mud plate frame 1. The other side of each of the two connecting blocks 46 is fixedly connected to the inner wall of the mud plate frame 1, which realizes the function of sensing the extrusion deformation of the mud plate frame 1 and transmitting the force. The inside of the moving ring 43 is provided with a guide component 47, which realizes the function of limiting and guiding the movement direction of the moving ring 43. The guide assembly 47 includes two guide blocks 471, which cooperate with the guide groove 472 to perform sliding guidance. Both guide blocks 471 are fixedly connected to the inner side of the moving ring 43, which realizes the function of assembling the guide assembly 47 with the moving ring 43. The outer wall of the crossbar 21 is provided with multiple guide grooves 472, which realizes the function of providing a sliding trajectory for the guide blocks 471. The guide blocks 471 are slidably connected to the middle of the guide grooves 472, which realizes the function of preventing the moving ring 43 from rotating and deviating on the outer wall of the crossbar 21. Specifically, the support mechanism 4 uses the fixed ring 41, which is fixedly connected to the outer wall of the crossbar 21, as the core support base. The return springs 42 connected on both sides are connected to the moving ring 43 respectively. The connecting block 44 at the bottom of the moving ring 43 is rotatably connected to the rotating plate 45. The bottom end of the rotating plate 45 is fixed to the inner wall of the mud plate frame 1 through the connecting block 46. When the mud plate is squeezed and the mud plate frame 1 shrinks inward, it will push the connecting block 46 to drive the rotating plate 45 to rotate towards the middle, thereby pushing the connecting block 44 to drive the moving ring 43 to move towards the fixed ring 41, squeezing the return spring 42 to absorb the external squeezing force, thereby improving the support and buffering effect on the mud plate frame 1. At the same time, the two guide blocks 471 on the inner side of the moving ring 43 are slidably connected in the guide groove 472 on the outer wall of the crossbar 21, which can effectively prevent the moving ring 43 from rotating on the outer wall of the crossbar 21 and ensure the stable operation of the support mechanism 4.

[0026] Reference Figure 6 , Figure 7 and Figure 8 A guide rod 5 is fixedly connected to the inner wall of the moving groove 35, providing a stable guide trajectory for the movement of the connecting plate 37. The guide rod 5 passes through one side of the connecting plate 37, limiting the offset of the connecting plate 37 during movement. Slider blocks 6 are fixedly connected to both sides of the pushing block 395, cooperating with the sliding groove 7 for sliding limit. The cylinder 391 has a sliding groove 7 inside, providing sliding space for the slider 6. The slider 6 is slidably connected to the middle of the sliding groove 7, preventing the pushing block 395 from tilting or jamming during sliding. Yes, the two ends of the crossbar 21 are fitted with gaskets 8 to increase the contact area between the threaded ring 23 and the inner wall of the mud plate frame 1. One side of the gasket 8 is in contact with the threaded ring 23 to improve the fixing stability of the threaded ring 23 on the crossbar 21. The two sides of the extrusion block 394 are in contact with one side of the push block 395 to efficiently transmit the force of the extrusion block 394 to the push block 395. One side of both the extrusion block 394 and the push block 395 are inclined to convert the lateral thrust of the extrusion block 394 into the outward expansion force of the push block 395. Specifically, the guide rod 5, which is fixedly connected to the inner wall of the moving groove 35, passes through one side of the connecting plate 37 and guides the movement of the connecting plate 37 within the moving groove 35, ensuring the stability of its movement trajectory. The sliders 6, which are fixedly connected to both sides of the pushing block 395, are slidably connected in the grooves 7 inside the cylinder 391, which limits the sliding direction of the pushing block 395 and prevents it from deviating during movement. One side of the gaskets 8 sleeved at both ends of the crossbar 21 is in contact with the threaded ring 23, which increases the contact area between the threaded ring 23 and the inner wall of the mud plate frame 1, improves the fixing effect of the threaded ring 23 on the crossbar 21, and also plays a role in buffering and protection. The two sides of the extrusion block 394 are in contact with one side of the pushing block 395, and both sides are inclined. This structure can efficiently convert the lateral thrust of the extrusion block 394 into the outward expansion force of the pushing block 395, ensuring that when the rotating rod 393 is rotated, the pushing block 395 can move outward quickly and fit tightly with the inner wall of the mud plate frame 1.

[0027] Reference Figure 9 The diagram shows the production process of mud board frame 1. The raw material is extruded and molded into mud board frame 1 by pressing the lower mold with the upper mold. Mud board frame 1 has an arc shape and a lightweight design, which facilitates integrated manufacturing. It has high strength and long service life due to one-time stamping. It is made of Q235 and Q195 carbon structural steel.

[0028] Working principle: When it is necessary to install the motorcycle front fender on the fender frame 1, first rotate the threaded ring 23 to move it to both ends to fit against the inner wall of the fender frame 1 and fix the crossbar 21. At this time, rotate the threaded ring 24 to adjust the rotating ring 25 to move left and right to adapt to different widths of fenders. Rotate the mounting plate 210 to rotate on the outer wall of the threaded post 28 to adapt to different installation positions. Rotate the fixing ring 211 to limit and fix the mounting plate 210. When it is necessary to adjust the distance between the fender and the wheel, rotate the rotating rod 292 to drive the positioning tooth 293 to move outward and disengage from the positioning tooth 291 to cancel the limitation on the lifting bracket 27. At the same time, pull the lifting bracket 27 to move upward and drive the fender to move upward to increase the distance between the fender and the wheel. When it moves to the required position, rotate the rotating rod 292 to push the positioning tooth 293 to move inward and engage with the positioning tooth 291 to limit and fix the lifting bracket 27. When it is necessary to install the mudguard frame 1 on the motorcycle, first insert the cylinder 391 into the inside of the mudguard frame 1, and at the same time rotate the rotating rod 393 to push the extrusion block 394 to move. At the same time, the pushing blocks 395 on both sides of the extrusion block move outward and fit against the inner wall of the mudguard frame 1. At this time, rotate the connecting plate 33 to install the mounting ring 34 on the front bumper of the motorcycle. At the same time, rotate the threaded rod 36 to drive the connecting plate 37 and the mounting ring 38 to move towards the mounting ring 34 in the moving groove 35. The mounting ring 34 and the mounting ring 38 are clamped on the front bumper. Rotate the fixing bolt 311 to fix the mounting ring 34 and the mounting ring 38. Finally, when the mudguard is squeezed, the mudguard frame 1 is squeezed inward. At this time, the connecting block 2 46 is pushed to drive the rotating plate 45 to move towards the middle. At the same time, the connecting block 1 44 is pushed to drive the moving ring 43 to move towards the middle and squeeze the fixed ring 1 41 to push the reset spring 42 to absorb the external pressure and improve the support force. The guide block 471 slides in the guide groove 472 to prevent the moving ring 43 from rotating on the outer wall of the crossbar 21.
