Description

Technical Field

[0001] This utility model relates to the field of mudguard technology, specifically a self-draining mudguard structure with a flow guide groove. Background Technology

[0002] Mudguards, as essential protective accessories for vehicles, are primarily used to block mud, water, stones, and other debris kicked up by tires during driving, preventing them from splashing onto the vehicle body or surrounding components. Traditional mudguards are mostly fixed directly to the vehicle body with bolts, and the bolt connection lacks an effective sealing structure. Mud and water can easily seep in through the bolt gaps or the seams between the mudguard and the vehicle body, leading to corrosion of the connecting parts and affecting the vehicle's lifespan. At the same time, the surface of existing mudguards is mostly flat or simply curved, lacking a directional flow guidance structure. Mud and water splashed onto the surface tend to spread irregularly, with some mud and water lingering at the edges and in recesses of the mudguard. Traditional mudguards are mostly designed with a fixed length, making it difficult to adjust the mud-blocking range according to changes in tire size or different usage scenarios. Although some adjustable mudguards can extend or retract in length, the flow guidance structure is prone to misalignment after adjustment, resulting in a broken drainage path and an inability to maintain continuous mud-blocking and drainage functions, thus limiting their adaptability and practicality. In response to the problems of poor sealing, inefficient drainage, and poor adaptability of the existing technologies, there is an urgent need to develop a mudguard structure with efficient sealing and waterproofing, directional drainage, and flexible telescopic adjustment functions to improve the protective performance and ease of use of mudguards and meet the diverse protection needs of vehicles.

[0003] Public technical solution CN223086122U discloses an improved vehicle mudguard, including a front body and a rear bonding plate. This design eliminates any connection holes on the front of the mudguard body, making it easy to wash and, most importantly, preventing mud from entering the vehicle body, thus ensuring interior cleanliness. Even if wastewater enters the rear from the connection between the top of the mudguard and the vehicle body, it is blocked by the outer bonding plate and flows downwards to the inner bonding plate, preventing contamination of the vehicle's exterior. However, the existing technical solution still has some shortcomings in practical implementation. The surface of the main body of the device is planar, lacking a directional flow design. When the vehicle is moving, mud and water splashed by the tires tend to spread irregularly after hitting the plane, failing to form a concentrated drainage path. Some mud and water, affected by surface tension and mud friction, tend to stagnate at the edges of the mudguard and in the recesses where it connects to the vehicle body. Long-term accumulation can easily form sludge that clogs the gaps, reducing drainage efficiency and requiring frequent manual cleaning, increasing maintenance costs. Utility Model Content

[0004] Given that the existing technology has a planar surface structure and lacks a directional flow design, mud and water splashed up by the tires when the vehicle is driving tend to spread irregularly after hitting the surface, making it impossible to form a concentrated drainage path; some mud and water will remain at the edge of the mudguard and in the recesses where it connects to the vehicle body due to surface tension and mud friction, and long-term accumulation can easily form dirt that clogs the gaps, reducing drainage efficiency and requiring frequent manual cleaning, which increases maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A self-draining mudguard structure with a flow guide groove includes a protective component and an adjustment component for length adjustment. The protective component includes: a main body; and a main water inlet channel formed on the surface of the main body; The adjustment assembly includes: an adjustment screw disposed inside the main body; and a protective knob keyed to the upper end of the adjustment screw.

[0006] As a further embodiment of this utility model: the protective component further includes: a bonding plate and a vehicle body; the bonding plate is fixed to the rear end of the main body, and the bonding plate is L-shaped; the vehicle body is disposed on the upper end of the horizontal plate of the bonding plate.

[0007] As a further embodiment of this utility model: the protective component further includes: an extension plate and an extension section water inlet groove; the extension plate is threaded to the surface of the adjusting screw; the extension section water inlet groove is formed on the surface of the extension plate, and the surface of the extension plate has a plurality of evenly distributed extension section water inlet grooves.

[0008] As a further embodiment of this utility model: the protective component further includes: a secondary water inlet trough; the secondary water inlet trough is horizontally opened on both sides of the main water inlet trough, the secondary water inlet trough is inclined, the two ends of the secondary water inlet trough are respectively connected to the adjacent main water inlet trough, and the surfaces of the main water inlet trough and the secondary water inlet trough are provided with an anti-stick coating.

[0009] As a further improvement of this utility model, the protective component further includes: a scraper and a scraper block; the scraper is fixed to the lower end of the main body; and the scraper block is disposed on one side of the scraper.

[0010] As a further improvement of this utility model, the adjustment component further includes a limiting block; the limiting block is fixed to the upper right side of the extension plate, and a sliding groove is provided on one side of the main body corresponding to the limiting block.

[0011] As a further improvement of this utility model: a fixing component is provided on the rear side of the protective component, the fixing component including: a claw and a fixing bolt; the claw is located on the right side of the vertical plate of the bonding plate; the fixing bolt passes through the interior of the horizontal plate of the bonding plate, and the bonding plate is fixed to the lower end of the vehicle body by the fixing bolt.

[0012] As a further embodiment of this utility model: the fixing component further includes: a sealing ring and a drain hole; the sealing ring is sleeved on the surface of the fixing bolt; the drain hole is opened in the middle of the cross plate of the bonding plate.

[0013] The beneficial effects of this utility model are: 1. When the inserter is inserted into the pre-set hole in the vehicle body, the sealing ring inside the hole forms the first waterproof barrier. The sealing ring inside the countersunk hole of the bonding plate is compressed after the fixing bolts are tightened, preventing mud and water from seeping in through the bolt gaps. Even if a small amount of water seeps into the bonding plate area, the drainage hole in the middle can quickly drain it. The triple protective structure works together to prevent mud and water from entering the vehicle body and affecting the performance of components, and also avoids corrosion problems caused by water accumulation in the bonding plate area.

[0014] 2. This utility model features an arc-shaped structure at the front end of the main body that adapts to the tire contour, which reduces the impact of mud and water splashing and guides the mud and water to converge into the main water intake channel. The horizontally inclined secondary water intake channel can guide the dispersed mud and water to the adjacent main water intake channels on both sides, and achieve rapid drainage in conjunction with the through path in the height direction of the main water intake channel. At the same time, the anti-stick coating on the surface of the main water intake channel and the secondary water intake channel reduces the adhesion of mud and water, further reducing the probability of mud and dirt accumulation, significantly reducing the frequency of manual cleaning, and improving the drainage stability of the mudguard during long-term use.

[0015] 3. This utility model uses a rotating protective knob to drive the adjusting screw to rotate, causing the threaded extension plate to extend and retract along the main body groove. The length can be flexibly adjusted according to changes in tire size or mud-blocking range requirements. The upper right limit block of the extension plate can prevent deviation during extension and retraction, ensuring that the water channel of the extension section is aligned with the main water channel of the main body to form a continuous flow path. When the extension plate retracts, the scraper and scraper block can scrape off the mud and water on the surface and in the groove respectively, ensuring that the mudguard still maintains efficient mud-blocking and drainage capabilities after adjustment, adapting to different vehicle models and usage scenarios.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example 1: Please refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a self-draining mudguard structure with a flow guide groove, including a protective component 1 and an adjustment component 2 for length adjustment. The protective component 1 includes: a main body 101; and a main water channel 103 formed on the surface of the main body 101; The adjustment assembly 2 includes: an adjustment screw 201 disposed inside the main body 101; and a protective knob 202 keyed to the upper end of the adjustment screw 201.

[0020] Specifically, the protective component 1 also includes: a bonding plate 107 and a body 102; the bonding plate 107 is fixed to the rear end of the main body 101, and the bonding plate 107 is L-shaped; the body 102 is disposed on the upper end of the horizontal plate of the bonding plate 107.

[0021] Furthermore, a sealing ring 303 is installed in the pre-set insertion hole of the vehicle body 102 to prevent mud and water from entering.

[0022] Specifically, the protective component 1 also includes: an extension plate 105 and an extension section water channel 106; the extension plate 105 is threaded to the surface of the adjusting screw 201; the extension section water channel 106 is formed on the surface of the extension plate 105, and the surface of the extension plate 105 has a number of evenly distributed extension section water channels 106.

[0023] Furthermore, the extended section water inlet channel 106 evenly distributed on the surface of the extension plate 105 forms a continuous flow path with the main water inlet channel 103 of the main body 101.

[0024] Specifically, the protective component 1 also includes: a secondary water inlet trough 104; the secondary water inlet trough 104 is horizontally opened on both sides of the main water inlet trough 103, the secondary water inlet trough 104 is inclined, and the two ends of the secondary water inlet trough 104 are respectively connected to the adjacent main water inlet trough 103, and the surfaces of the main water inlet trough 103 and the secondary water inlet trough 104 are provided with anti-stick coatings.

[0025] Furthermore, the horizontally inclined secondary water intake channel 104 utilizes the slope to gather mud and water to both sides, and finally discharges them quickly along the vertical path through the adjacent main water intake channel 103 connected at both ends.

[0026] During use, the mud and water kicked up by the tire are first blocked by the main body 101. The front end of the main body 101 has an arc-shaped structure that matches the tire's contour, reducing the impact of mud and water splashing onto the surface of the main body 101. At the same time, it makes it easier for the mud and water to gather in the main water channel 103. After the dispersed mud and water fall onto the surface of the main body 101, the horizontally inclined secondary water channel 104 uses the slope to gather the mud and water to both sides. Finally, it is quickly discharged through the adjacent main water channel 103 connected at both ends along the vertical path. At the same time, the anti-stick coating on the surface of the main water channel 103 and the secondary water channel 104 reduces the adhesion of mud and water and reduces the accumulation of dirt. When the tire size changes or the mudguard range needs to be expanded, the protective knob 202, which is keyed to the upper end of the adjusting screw 201, is rotated in the adjusting assembly 2. This causes the adjusting screw 201 to rotate inside the main body 101. Since the extension plate 105 is threadedly connected to the adjusting screw 201 and the upper right limit block 203 is embedded in the corresponding side groove of the main body 101, the rotation of the adjusting screw 201 causes the extension plate 105 to move up and down along the groove. The water channel 106 of the extension section, which is evenly distributed on the surface of the extension plate 105, forms a continuous flow path with the main water channel 103 of the main body 101, ensuring that the efficient drainage capacity is maintained after the extension.

[0027] In summary, when the inserter 301 is inserted into the pre-set insertion hole of the vehicle body 102, the sealing ring 303 inside the insertion hole forms the first waterproof barrier. The sealing ring 303 inside the countersunk hole of the cross plate of the bonding plate 107 is compressed after the fixing bolt 302 is tightened, preventing mud and water from seeping in through the bolt gap. Even if a small amount of water seeps into the cross plate area of ​​the bonding plate 107, the drainage hole 304 in the middle can quickly drain it. The triple protective structure works synergistically to prevent mud and water from entering the interior of the vehicle body 102 and affecting the performance of the components, and to avoid corrosion problems caused by water accumulation in the bonding plate 107 area. This invention features an arc-shaped structure at the front end of the main body 101 that adapts to the tire contour, which reduces the impact of mud and water splashing and guides the mud and water to converge into the main water intake channel 103. The secondary water intake channel 104, which is arranged laterally at an inclination, can guide the dispersed mud and water to the adjacent main water intake channels 103 on both sides, and achieve rapid drainage in conjunction with the through path in the height direction of the main water intake channel 103. At the same time, the anti-stick coating on the surface of the main water intake channel 103 and the secondary water intake channel 104 reduces the adhesion of mud and water, further reducing the probability of mud and dirt accumulation, significantly reducing the frequency of manual cleaning, and improving the drainage stability of the mudguard during long-term use.

[0028] Example 2: Please refer to Figures 1-5 This is the second embodiment of the present utility model.

[0029] Specifically, the protective component 1 also includes: a scraper 108 and a scraper block 109; the scraper 108 is fixed to the lower end of the main body 101; the scraper block 109 is disposed on one side of the scraper 108.

[0030] Furthermore, the scraper 108 and the extension plate 105 are tightly fitted together, the scraper block 109 and the extension section water channel 106 are tightly fitted together, and both the scraper 108 and the extension plate 105 are made of rubber.

[0031] Specifically, the adjustment component 2 also includes: a limiting block 203; the limiting block 203 is fixed to the upper right side of the extension plate 105, and the main body 101 has a sliding groove on one side corresponding to the limiting block 203.

[0032] Furthermore, the limiting block 203 prevents the extension plate 105 from shifting during extension and retraction, thereby ensuring the alignment of the guide channel.

[0033] Specifically, a fixing component 3 is provided on the rear side of the protective component 1. The fixing component 3 includes: a claw 301 and a fixing bolt 302; the claw 301 is located on the right side of the vertical plate of the bonding plate 107; the fixing bolt 302 passes through the interior of the horizontal plate of the bonding plate 107, and the bonding plate 107 is fixed to the lower end of the vehicle body 102 by the fixing bolt 302.

[0034] Furthermore, the insert claw 301 is fixed to the rear end of the main body 101, and the fixing bolt 302 passes through the countersunk hole of the horizontal plate of the bonding plate 107.

[0035] Specifically, the fixing component 3 also includes: a sealing ring 303 and a drain hole 304; the sealing ring 303 is sleeved on the surface of the fixing bolt 302; the drain hole 304 is opened in the middle of the horizontal plate of the bonding plate 107.

[0036] Furthermore, the sealing ring 303 inside the countersunk hole of the bonding plate 107 is compressed to prevent mud and water from seeping in from the bolt gap. A small amount of water that seeps into the bonding plate 107 horizontal plate area is discharged directly through the drainage hole 304 in the middle.

[0037] In use, first insert the claw 301 fixed to the right side of the vertical plate of the bonding plate 107 into the preset insertion hole of the body 102. The claw 301 is fixed to the rear end of the main body 101. A sealing ring 303 is provided in the preset insertion hole of the body 102 to prevent mud and water from entering. At this time, the initial positioning is formed. The horizontal plate of the bonding plate 107 has a countersunk hole, and a sealing ring 303 is provided in the countersunk hole. Then, the fixing bolt 302 is passed through the countersunk hole of the horizontal plate of the bonding plate 107 and then tightened into the threaded hole at the lower end of the body 102. The sealing ring 303 inside the countersunk hole of the bonding plate 107 is compressed to prevent mud and water from seeping in from the bolt gap. If a small amount of water seeps into the area of ​​the bonding plate 107, it will be discharged directly through the drainage hole 304 in the middle to avoid water accumulation. When the extension plate 105 retracts, the scraper 108 scrapes off the mud and water on the surface of the extension plate 105, and the scraper block 109 scrapes off the mud and water in the water channel 106 of the extension section. The limiting block 203 of the adjusting component 2 prevents the extension plate 105 from shifting during extension and retraction to ensure the alignment of the guide channel.

[0038] In summary, this utility model uses the rotating protective knob 202 to drive the adjusting screw 201 to rotate, causing the threaded extension plate 105 to extend and retract along the slide groove of the main body 101. The length can be flexibly adjusted according to changes in tire size or mud-blocking range requirements. The upper limit block 203 on the right side of the extension plate 105 can prevent deviation during extension and retraction, ensuring that the water channel 106 of the extension section is aligned with the main water channel 103 of the main body 101 to form a continuous flow path. Furthermore, when the extension plate 105 retracts, the scraper 108 and scraper block 109 can scrape away mud and water from the surface and inside the channel, ensuring that the mudguard still maintains efficient mud-blocking and drainage capabilities after adjustment, making it suitable for different vehicle models and usage scenarios.

[0039] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
