They effectively shield the vehicle from mud, water, sand and gravel splashed up during driving, protecting the vehicle body from damage. They also reduce road noise and the impact of debris on the chassis, improving driving safety and the vehicle's appearance.
[0003] The patent document with publication number CN221938310U discloses an angle-adjustable mudguard, including a top plate. Both ends of the top plate are equipped with connecting pipes. The connecting pipes are rotatably connected to a rotating rod through a sliding groove. The connecting pipe in front of the rotating rod has an installation groove. A gear is installed in the installation groove in front of the rotating rod. A locking component is installed at the upper end of the connecting pipe above the gear. A handle is installed at the front end of the gear through the connecting rod. The surface of the connecting pipe has a rotating groove.
[0004] In the process of realizing this utility model, the inventors discovered that:
[0005] When using the above technical solution, the user needs to rotate the component and use the locking teeth to adjust and fix the angle of the mudguard assembly that rotates the gear. This process is cumbersome and time-consuming. At the same time, this fixing method is not stable enough. Especially under bumpy or high-speed road conditions, the angle of the mudguard may change due to vibration, affecting the performance. Therefore, an angle-adjustable mudguard is provided to solve the above problems. Summary of the Invention
[0006] In order to solve the problems existing in the prior art, this utility model provides an angle-adjustable mudguard, which has the advantages of stable angle adjustment and flexible and convenient operation.
[0007] Therefore, the technical solution of this utility model is as follows: an angle-adjustable mudguard, including a top fixed plate, a rotating fixed seat fixedly connected to the side of the top fixed plate, a fixed rotating shaft rotatably connected to the side of the rotating fixed seat, a side mudguard fixedly connected to the side of the fixed rotating shaft, side fixed rotating arms fixedly connected to both ends of the fixed rotating shaft through the rotating fixed seat, a dual-axis motor fixedly connected to the bottom of the top fixed plate, a set of threaded rods fixedly connected to the two sets of rotating shafts of the dual-axis motor, a top mudguard fixedly connected to the bottom of the top fixed plate, a side moving plate provided on the side of the side fixed rotating arm, a protrusion moving groove opened on the side of the side moving plate, an upper limit slider fixedly connected to the top of the side moving plate, a middle connecting crossbar fixedly connected to the side of the upper limit slider, a mudguard groove opened on the inner side of the middle connecting crossbar, an opening fixed seat fixedly connected to the top of the middle connecting crossbar, and a sliding protrusion fixedly connected to the side of the side fixed rotating arm near the side moving plate.
[0008] Furthermore, the number of rotating fixing seats is set to four sets, which are symmetrically fixed and connected on both sides of the top fixing plate.
[0009] Furthermore, one end of each of the two sets of threaded rods is fixedly connected to a set of rotating shafts of the dual-axis motor, and the other end of the threaded rod is rotatably connected to the inner side of the top mudguard.
[0010] Furthermore, a groove adapted to the upper limit slider is provided below the top fixed plate, so that the side moving plate can slide stably relative to the top fixed plate.
[0011] Furthermore, the inner side of the opening fixing seat is provided with a threaded hole that is compatible with the threaded rod.

[0013] Furthermore, the sliding bump is adapted to the bump moving groove.
[0014] Beneficial Effects: Compared with existing technologies, this invention uses a dual-axis motor to drive the threaded rod to rotate, achieving axial movement of the side moving plate, which in turn pushes the side fixed rotating arm to rotate around a fixed axis, thus easily adjusting the tilt angle of the side mudguard.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings, but this embodiment should not be construed as a limitation of this utility model.
[0021] This utility model is as follows Figures 1 to 4 As shown:
[0022] An angle-adjustable mudguard includes a top fixed plate 1, a rotating fixed seat 2 fixedly connected to the side of the top fixed plate 1, a fixed rotating shaft 3 rotatably connected to the side of the rotating fixed seat 2, a side mudguard 4 fixedly connected to the side of the fixed rotating shaft 3, and side fixed rotating arms 5 fixedly connected to both ends of the fixed rotating shaft 3 through the rotating fixed seat 2. A dual-axis motor 6 is fixedly connected below the top fixed plate 1, and a set of threaded rods 7 are fixedly connected to the two sets of rotating shafts of the dual-axis motor 6. A top mudguard 8 is fixedly connected below the top fixed plate 1. A side moving plate 9 is provided on the side of the side fixed rotating arm 5. A protrusion moving groove 10 is opened on the side of the side moving plate 9. An upper limit slider 11 is fixedly connected above the side moving plate 9, and a middle connecting crossbar is fixedly connected to the side of the upper limit slider 11. The rod 12 has a mudguard slot 13 on the inner side of the middle connecting crossbar 12. The middle connecting crossbar 12 is fixedly connected to the top of the hole fixing seat 14. The side fixed rotating arm 5 is fixedly connected to the side moving plate 9 with a sliding protrusion 15. When it is necessary to adjust the unfolding angle of the two side mudguards 4, it is only necessary to drive the dual-axis motor 6 to make its two sets of rotating shafts rotate synchronously, driving the threaded rod 7 to rotate. Since the threaded hole on the inner side of the hole fixing seat 14 is compatible with the threaded rod 7, the two side moving plates 9 will move synchronously along its axial direction with the rotation of the threaded rod 7, and move inward or outward at the same time. The sliding protrusion 15 moves up and down inside the protrusion moving slide groove 10, thereby pushing the side fixed rotating arm 5 to rotate around the fixed rotating shaft 3, thereby adjusting the tilt angle of the side mudguard 4.
[0023] The number of rotating fixing seats 2 is four sets, which are symmetrically fixed and connected to both sides of the top fixing plate 1. The setting of four sets of rotating fixing seats 2 ensures the stability and balance of the side mudguard 4 during the rotation process, and prevents displacement or damage caused by uneven force.
[0024] One end of each of the two sets of threaded rods 7 is fixedly connected to one set of rotating shafts of the dual-axis motor 6, and the other end of the threaded rods 7 is rotatably connected to the inner side of the top mudguard 8. This design enables the threaded rods 7 to rotate stably under the drive of the dual-axis motor 6, while ensuring that the side moving plate 9 can move smoothly along the axial direction of the threaded rods 7.
[0025] A groove adapted to the upper limit slider 11 is provided below the top fixed plate 1, so that the side moving plate 9 can slide stably relative to the top fixed plate 1. The upper limit slider 11 slides in the groove below the top fixed plate 1, providing stable guidance and limiting function for the side moving plate 9, preventing it from deviating or shaking during movement.
[0026] The inner side of the opening fixing seat 14 is provided with a threaded hole that matches the threaded rod 7. The opening fixing seat 14 cooperates with the threaded rod 7 through the threaded hole on its inner side, realizing the axial movement of the side moving plate 9 along the threaded rod 7. The mudguard slot 13 is adapted to the top mudguard 8, so that the middle connecting crossbar 12 can slide and connect with the top mudguard 8. The design of the mudguard slot 13 allows the middle connecting crossbar 12 to slide smoothly along the top mudguard 8, providing additional stability and support for the angle adjustment of the side mudguard 4. The inner side of the mudguard slot 13 is fixedly connected with cleaning bristles that are close to the bottom of the top mudguard 8, so that the middle connecting crossbar 12 can clean the bottom of the top mudguard 8 at the same time when it moves. The sliding protrusion 15 is adapted to the protrusion moving slide groove 10. The sliding protrusion 15 moves up and down in the protrusion moving slide groove 10, providing the necessary guidance and limiting function for the rotation of the side fixed rotating arm 5.
[0027] The working principle of this utility model:
[0028] When it is necessary to adjust the angle of the side mudguard 4, start the dual-axis motor 6. The two sets of rotating shafts of the dual-axis motor 6 rotate synchronously, driving the two sets of threaded rods 7 to start rotating respectively. Since the threaded hole on the inner side of the opening fixing seat 14 is compatible with the threaded rod 7, as the threaded rod 7 rotates, the side moving plate 9 will move along the axial direction of the threaded rod 7. The side moving plates 9 on both sides will move inward or outward synchronously, depending on the rotation direction of the dual-axis motor 6.
[0029] As the side moving plate 9 moves, the sliding protrusion 15 moves up and down inside the protrusion moving groove 10. The movement of the sliding protrusion 15 pushes the side fixed rotating arm 5 to rotate around the fixed rotating shaft 3, thereby adjusting the tilt angle of the side mudguard 4.
[0030] While the side moving plate 9 moves, the upper limit slider 11 slides along the slot below the top fixed plate 1, and the middle connecting crossbar 12 slides smoothly along the top mudguard 8 through the mudguard slot 13. During the movement of the middle connecting crossbar 12, the cleaning bristles are in close contact with the bottom of the top mudguard 8, which plays a cleaning role. This can help keep the bottom of the top mudguard 8 clean and reduce the accumulation of dirt and impurities.
[0031] Any aspects not described in detail in this specification are techniques well-known in the art.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
