Description

Technical Field

[0001] This utility model relates to the field of automobile mudguard technology, and in particular to an automobile mudguard support structure. Background Technology

[0002] As an important component around the wheels of a car, mudguards primarily function to prevent mud, sand, and other debris from splashing onto the vehicle and the surrounding environment during driving, while also protecting other road users from the impact of these particles. Mudguards are generally made of materials such as plastic, rubber, or metal and are typically installed behind or on the sides of the wheels. With the continuous evolution of automotive exterior design and functional requirements, the support structure of mudguards is constantly being improved to enhance their ease of installation, stability, and adaptability to different vehicle models.

[0003] For example, Chinese utility model patent application number 202421883630.3 discloses a car mudguard support structure, relating to the field of automotive parts. It includes a first support rod, a second support rod, and a mudguard. A first slot and a second slot are provided on one side of the mudguard. The first support rod is inserted into the first slot, and the second support rod is inserted into the second slot. First mounting holes are provided on the surface of the mudguard at positions corresponding to the first and second slots, and first bolts are installed inside the first mounting holes. Both the first and second support rods are fixedly connected to the mudguard by the first bolts. The end of the second support rod located outside the mudguard is detachably connected to the wall of the first support rod. A mounting seat is fixedly provided at the end of the first support rod located outside the mudguard. This utility model provides support rods at both the top and bottom of the mudguard, increasing the support strength of the mudguard and making it less likely to detach under greater impact, thus improving its performance.

[0004] While the above solutions can ensure the mudguards are securely fixed to the wheel frame and effectively prevent mud and water from splashing, there are certain difficulties in the installation process, especially when the gap between the wheel frame and the wheel is small. Traditional installation methods often require the use of multiple bolts for fixing, and the installation positions of some bolts are relatively hidden, making the installation operation cumbersome and inconvenient. In addition, the traditional mudguards have a fixed length and cannot adapt to the differences in wheel arch size of different models, resulting in low versatility. Customization or the addition of shims is required when modifying them, which increases costs. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a car mudguard support structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a car mudguard support structure, including a wheel frame and a mudguard body. Two trapezoidal grooves are opened on one side of the wheel frame, and a trapezoidal frame is fixedly installed inside the trapezoidal grooves. Two fixing plates are fixedly installed on the front of the mudguard body. Each of the two fixing plates is provided with a fixing component for fixing the mudguard body. A square groove is opened at the bottom of the mudguard body, and a rotating groove is opened at the top of the mudguard body. A sleeve is rotatably connected inside the rotating groove. A limiting groove is opened inside the sleeve, and an extension component is provided at the bottom of the sleeve.

[0007] The trapezoidal frame is welded into the trapezoidal groove of the wheel frame. The inner wall is inclined to form a conical guide channel, which guides the trapezoidal block to slide in accurately and is pre-fixed to prevent it from falling off. The fixing plate serves as a load-bearing base and has through holes for positioning and fixing bolts. A square groove is opened at the bottom of the mudguard body with a rectangular guide rail cross section to constrain the extension plate to move only axially and prevent thread jamming caused by rotation. The sleeve transmits the torque of the knob and cooperates with the threaded block to extend the threaded rod from the sleeve. The outer wall of the sleeve and the inner wall of the rotating groove are provided with a micro-textured structure. When the sleeve rotates, it will have a certain friction with the rotating groove. When static, it maintains sufficient static friction to resist vibration interference.

[0008] As a further description of the above technical solution:

[0009] Two trapezoidal blocks are fixedly installed on the side of the mudguard body near the wheel frame, and the outer wall of the trapezoidal blocks is slidably connected to the inside of the trapezoidal frame.

[0010] The trapezoidal block and the trapezoidal frame are fitted with a clearance to achieve axial sliding installation, eliminating the need for bolt alignment and reducing the required operating space.

[0011] As a further description of the above technical solution:

[0012] The fixing assembly includes a fixing bolt that runs through the front of the two fixing plates, and a flower nut is fixedly installed at one end of the fixing bolt.

[0013] The fixing bolts pass horizontally through the fixing plate, are adapted to the threaded holes of the wheel frame, and are locked from the side. They can be operated from the outside of the wheel, avoiding the narrow space inside the wheel hub.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the fixing bolt penetrates the fixing plate and is threadedly connected to the hole on the wheel frame.

[0016] As a further description of the above technical solution:

[0017] The extension assembly includes a threaded block fixedly installed at the bottom of the sleeve, and the inner wall of the threaded block is threadedly connected to a threaded rod.

[0018] The threaded block is fixed to the bottom of the sleeve and has a fine thread embedded in it, which converts the rotational motion into linear motion. The fine thread enables high-precision adjustment.

[0019] As a further description of the above technical solution:

[0020] The top end of the threaded rod is fixedly connected to a limiting block, and the outer wall of the limiting block slides along the limiting groove.

[0021] The limiting block is rigidly connected to the top of the threaded rod and is embedded in the sleeve limiting groove to prevent the threaded rod from completely coming out.

[0022] As a further description of the above technical solution:

[0023] An extension plate is fixedly installed at the bottom of the threaded rod, and the outer wall of the extension plate slides along the square groove.

[0024] The extension plate is fixed to the bottom of the threaded rod, and its edge slides into the square groove, which can expand the protection area of ​​the mudguard.

[0028] This utility model has the following beneficial effects:

[0029] 1. Compared with the existing technology, the car mudguard support structure, through the combined use of a fixing plate, a trapezoidal frame, a trapezoidal block and fixing components, can easily fix the mudguard to the wheel frame through the sliding engagement of the trapezoidal block and the trapezoidal frame. Furthermore, the fixing plate and fixing components on the front can be used for installation from the front, avoiding the inconvenience caused by the limited operating space. This not only simplifies the installation steps but also ensures that the mudguard body is stably fixed.

[0030] 2. Compared with the existing technology, this car mudguard support structure, through the combined use of extension components, sleeves, rotating grooves and square grooves, can rotate the anti-slip knob to drive the sleeve to rotate, so that the threaded rod extends out from the sleeve, thereby achieving the effect of adjusting the length of the mudguard. This allows the mudguard body to adapt to more types of vehicles, making the product have a wider range of applications. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figure 1-4This utility model provides a car mudguard support structure, including a wheel frame 1 and a mudguard body 2. Two trapezoidal grooves 3 are formed on one side of the wheel frame 1, and a trapezoidal frame 4 is fixedly installed inside the trapezoidal grooves 3. Two fixing plates 5 are fixedly installed on the front of the mudguard body 2. Each fixing plate 5 has a fixing component for fixing the mudguard body 2. A square groove 6 is formed at the bottom of the mudguard body 2, and a rotating groove 7 is formed at the top of the mudguard body 2. A sleeve 8 is rotatably connected inside the rotating groove 7. A limiting groove 9 is formed inside the sleeve 8, and an extension component is provided at the bottom of the sleeve 8. The trapezoidal frame 4 is welded into the trapezoidal groove 3 of the wheel frame 1, with an inclined inner wall forming a conical guide channel to guide the trapezoidal block 10 to slide in accurately, pre-fixing to prevent detachment. The fixing plate 5 serves as a load-bearing base, with through holes for positioning and fixing bolts 11. 6 is located at the bottom of the mudguard body 2, with a rectangular guide rail cross-section. It constrains the extension plate 16 to move only axially, preventing thread jamming caused by rotation. The sleeve 8 transmits the knob torque and, in conjunction with the threaded block 13, extends the threaded rod 14 from the sleeve 8. The outer wall of the sleeve 8 and the inner wall of the rotating groove 7 are provided with a micro-textured structure. When the sleeve 8 rotates, it will have a certain friction with the rotating groove 7. When static, it maintains sufficient static friction to resist vibration interference. Through the cooperation of the fixing plate 5, trapezoidal frame 4, trapezoidal block 10 and fixing components, the mudguard can be easily fixed to the wheel frame 1 through the sliding cooperation between the trapezoidal block 10 and the trapezoidal frame 4. Furthermore, through the fixing plate 5 and fixing components on the front, it can be installed from the front, avoiding the inconvenience caused by the narrow operating space. This not only simplifies the installation steps but also makes the mudguard body 2 stably fixed.

[0039] Two trapezoidal blocks 10 are fixedly installed on the side of the mudguard body 2 near the wheel frame 1. The outer wall of the trapezoidal block 10 is slidably connected to the inside of the trapezoidal frame 4. The trapezoidal block 10 and the trapezoidal frame 4 are clearance-fitted to achieve axial sliding installation, eliminating the need for bolt hole alignment and reducing the operating space requirement.

[0040] The fixing assembly includes a fixing bolt 11 that passes through the front of the two fixing plates 5. A flower nut 12 is fixedly installed at one end of the fixing bolt 11. The fixing bolt 11 passes horizontally through the fixing plate 5 and is adapted to the threaded hole of the wheel frame 1. It is laterally locked and operated from the outside of the wheel to avoid the narrow space inside the wheel hub. The outer wall of the fixing bolt 11 passes through the fixing plate 5 and is threadedly connected to the hole on the wheel frame 1.

[0041] The extension assembly includes a threaded block 13 fixedly installed at the bottom of the sleeve 8. The inner wall of the threaded block 13 is threadedly connected to a threaded rod 14. The threaded block 13 is fixed at the bottom of the sleeve 8 and has a fine thread embedded in it, which converts the rotational motion into linear motion. The fine thread enables high-precision adjustment.

[0042] The top end of the threaded rod 14 is fixedly connected to a limiting block 15. The outer wall of the limiting block 15 slides along the limiting groove 9. The limiting block 15 is rigidly connected to the top of the threaded rod 14 and is embedded in the limiting groove 9 of the sleeve 8 to prevent the threaded rod 14 from completely coming out.

[0043] An extension plate 16 is fixedly installed at the bottom of the threaded rod 14. The outer wall of the extension plate 16 slides along the square groove 6. The extension plate 16 is fixed to the bottom end of the threaded rod 14, and its edge slides in fit with the square groove 6, which can expand the protection area of ​​the mudguard.

[0044] The top of the sleeve 8 is provided with an anti-slip button 17, which is fixed to the top of the sleeve 8 and has a knurled surface to provide hand-tightening operation.

[0045] Working principle: First, when using the device, the trapezoidal block 10 on the mudguard body 2 can be aligned with the trapezoidal frame 4 on the wheel frame 1 from the front. Then, the operator can push the trapezoidal block 10 into the trapezoidal frame 4 from the front. The mudguard body 2 is firmly fixed to the wheel frame 1 through the cooperation of the trapezoidal block 10 and the trapezoidal frame 4. Then, the fixing bolt 11 is inserted into the hole of the fixing plate 5, and the nut 12 is screwed in to make the fixing bolt 11 screw into the wheel frame 1, thereby fixing the structure. Through the sliding cooperation between the trapezoidal block 10 and the trapezoidal frame 4, the mudguard can be easily fixed to the wheel frame 1, thus simplifying the installation process. Moreover, since the device is fixed from the front, it is not constrained by the limited operating space, making it convenient to install and fix.

[0046] When the length of the mudguard needs to be adjusted, the anti-slip knob 17 can be rotated to rotate the sleeve 8, which in turn causes the threaded block 13 to rotate. At this time, the extension plate 16 at the bottom of the threaded rod 14 located in the threaded block 13 is constrained by the guide constraint of the square groove 6, pushing the extension plate 16 to extend straight out from the sleeve 8, thereby extending the length of the mudguard body 2. Then, when the threaded rod 14 moves from the sleeve 8, the limiting block 15 at the top of the threaded rod 14 will move vertically under the restriction of the limiting groove 9 on the inner wall of the sleeve 8, ensuring that the threaded rod 14 will not move out of the sleeve 8, thus limiting it. The threaded rod 14 can extend or retract under the restriction of the extension plate 16, thereby adjusting the length of the mudguard body 2 and improving the adaptability of the structure.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
