Description

Technical Field

[0001] The present application relates to the field of mudguards, and particularly to a mudguard with an extended service life. Background Art

[0002] A mudguard is a plate-like structure installed behind the outer frame of a wheel, usually made of high-quality rubber or engineering plastics. It is mainly used to block and shield the sediment and sewage thrown out by the wheel, preventing the sediment and sewage from splashing onto automotive parts (such as automotive tie rods, ball heads, etc.) around the wheel, causing corrosion. It can also provide safety protection for the whole vehicle, preventing stones, gravel, etc. thrown out by the wheel from damaging the vehicle body.

[0003] For example, the utility model patent with the patent publication number CN221114105U discloses a new type of automotive mudguard, including a mudguard body. A plurality of mounting holes are processed above the front end of the mudguard body. A plurality of cross bars are fixedly connected below the front end of the mudguard body. Vertical plates are fixedly connected to the outer walls of the rear ends of the plurality of cross bars. A noise reduction device is installed at the front end of the cross bar, and a connecting device is installed at the front end of the vertical plate, having the characteristic of reducing tire noise.

[0004] When using the above mudguard, when the vehicle is driving on an uneven road section, the mudguard may collide and wear with the raised parts on the road section, resulting in damage to the lower half of the mudguard, and the mudguard needs to be replaced in time, shortening the service life of the mudguard, which needs to be improved. Summary of the Invention

[0005] In order to extend the service life of the mudguard, the present application provides a mudguard with an extended service life.

[0006] A mudguard with an extended service life provided by the present application adopts the following technical solutions:

[0007] A mudguard with an extended service life includes a plate body. An extension plate is slidably moved up and down on the plate body. The extension plate is located below the plate body. A receiving cavity is formed in the plate body. An opening and a first through hole are formed in the outer side wall of the plate body. The opening and the first through hole are located on the same side of the plate body. The first through hole is located below the opening, and both the opening and the first through hole communicate with the receiving cavity. A fixing block is provided on the extension plate, and the fixing block is located in the receiving cavity.

[0008] By adopting the above technical scheme, when the car is driving on an uneven road section, the raised part on the road section comes into contact with the extension plate, and the extension plate moves under the push of the road surface to adapt to the ups and downs of the road section, thereby reducing the impact and subsequent damage between the fender and the road surface, which is beneficial to extending the service life of the fender; the mud, sand and stones thrown out by the rotation of the wheel enter the accommodating cavity through the opening and fall onto the fixed block, and the water is discharged through the through hole. Solid objects such as stones and gravel remain on the fixed block to exert pressure on the extension plate, making it difficult for the extension plate to reciprocate significantly under the bumps caused by the driving of the car, thereby reducing the wear between the extension plate and the plate body, which is beneficial to further extending the service life of the fender, and can also reduce the sound made by the fixed block hitting the plate body, thereby achieving noise reduction.

[0009] Optionally, a slope 1 is provided on the fixing block, and the slope 1 is located above the fixing block, and the slope 1 is inclined upward in a direction away from the through hole.

[0010] By adopting the above technical solution, inclined plane 1 is set. When the fixed block moves upward so that inclined plane 1 is aligned with the opening, the solid matter on inclined plane 1 will slide along inclined plane 1 toward the opening and then break away from the fixed block. After the fixed block falls back to the bottom of the accommodating cavity, the mud, sand and gravel thrown out by the rotation of the wheel will re-enter the accommodating cavity, thereby realizing the continuous renewal of the solid matter in the accommodating cavity and reducing the situation where the movement of the fixed block is hindered due to the hardening of mud and sand.

[0011] Optionally, an elastic sheet is provided on the plate body, the elastic sheet is located in the accommodating cavity and above the fixing block, and a push block is provided at the lower end of the elastic sheet.

[0012] By adopting the above technical solution, an elastic sheet and a push block are provided. When the fixed block moves upward, the deformation ability of the elastic sheet is utilized, and the push block abuts against inclined surface one and tilts along inclined surface one toward the direction close to the opening, thereby pushing the solid objects on the fixed block out of the opening, reducing the adhesion of solid objects such as mud and sand on the fixed block.

[0013] Optionally, a second inclined surface is provided on the push block, the second inclined surface is located below the push block, and the second inclined surface is inclined upward in a direction close to the through hole.

[0014] By adopting the above technical solution, inclined plane 2 is provided so that the lower end of the push block forms a pointed end. When the solid objects on the fixed block are accumulated higher than inclined plane 1, it is convenient for the push block to penetrate the solid objects and abut against inclined plane 1.

[0015] Optionally, the distance between the push block and the inner wall of the accommodating groove away from the opening is 3-5 mm.

[0016] By adopting the above technical solution, it is convenient for the upper end of the fixing block to extend between the pushing block and the inner wall of the receiving groove far away from the opening, so as to push the pushing block to tilt in the direction close to the opening.

[0017] Optionally, the distance between the elastic sheet and the inner wall of the receiving groove far away from the opening is 3-5 mm.

[0018] By adopting the above technical solution, an activity space is provided for the deformation of the elastic sheet. When the sediment and stones thrown out by the rotation of the wheel enter through the opening, the sediment and stones impact the pushing block, and the elastic sheet buffers the sediment and stones through its elasticity, which can reduce the sound generated by the sediment and stones hitting the inner wall of the receiving cavity and has a noise reduction effect.

[0019] Optionally, a second through hole is also provided on the outer side wall of the plate body. The second through hole is located between the opening and the first through hole and communicates with the receiving cavity, and the second through hole is inclined downward in the direction close to the receiving cavity.

[0020] By adopting the above technical solution, when the muddy water is splashed onto the plate body by the flinging of the wheel, the muddy water flows down along the surface of the plate body and enters the receiving cavity along the second through hole to moisten the solid matter in the receiving cavity, and the excess muddy water is discharged through the first through hole, thereby inhibiting the hardening of the solid matter in the receiving cavity.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. When the vehicle is driving on an uneven road section, the extension plate can move to adapt to the undulation of the road section, thereby reducing the impact between the mudguard and the road surface and being damaged, which is beneficial to extending the service life of the mudguard. The sediment and stones thrown out by the rotation of the wheel enter the receiving cavity through the opening and fall on the fixing block to apply pressure to the extension plate, so that the extension plate is not prone to large reciprocating movement under the bumps generated during the driving of the vehicle, thereby reducing the wear of the extension plate, being beneficial to further extending the service life of the mudguard, and also reducing the sound generated by the fixing block hitting the plate body to achieve noise reduction;

[0023] 2. By providing the first inclined surface, continuous update of the solid matter in the receiving cavity can be realized, and the situation that the movement of the fixing block is blocked due to the hardening of the sediment is reduced;

[0024] 3. By providing the elastic sheet and the pushing block, when the fixing block moves upward, by using the deformation ability of the elastic sheet, the pushing block abuts against the first inclined surface and tilts in the direction close to the opening along the first inclined surface, thereby pushing the solid matter on the fixing block out of the opening and reducing the adhesion of solid matters such as sediment on the fixing block.

[0025] 4. By providing the second through hole, when mud and water are splashed onto the plate body under the flinging of the wheel, the mud and water enter the accommodating cavity through the second through hole to moisten the solid matter in the accommodating cavity, thereby inhibiting the hardening of the solid matter in the accommodating cavity.

An opening 13 and a plurality of first through holes 14 are formed on the outer side wall of the plate body 1. The opening 13 and the plurality of first through holes 14 are both located on the same side of the plate body 1. In actual use, the opening 13 and the first through holes 14 are located on the side of the plate body 1 facing the wheel. The plurality of first through holes 14 are all located below the opening 13 and are evenly spaced in the horizontal direction, and both the opening 13 and the plurality of first through holes 14 communicate with the accommodating cavity 12.

[0032] Refer to Figures 1-3 , a plurality of second through holes 15 are further formed on the outer side wall of the plate body 1. The plurality of second through holes 15 are located on the side of the plate body 1 close to the opening 13 and between the opening 13 and the first through holes 14. The plurality of second through holes 15 are evenly spaced both horizontally and vertically. The plurality of second through holes 15 all communicate with the accommodating cavity 12, and each second through hole 15 is inclined downward towards the accommodating cavity 12.

[0033] Refer to Figures 1-3An extension plate 2 is provided in the slide groove 11 for lifting and sliding. The extension plate 2 is located below the plate body 1. A fixed block 3 is fixed to the upper end of the extension plate 2. The fixed block 3 is located in the accommodating cavity 12, and the outer peripheral wall of the fixed block 3 is arranged to fit the inner wall of the accommodating groove. An inclined surface 4 is formed on the outer wall of the fixed block 3. The inclined surface 4 is located above the fixed block 3, and the inclined surface 4 is inclined upward in the direction away from the through hole.

[0034] See also Figures 1-3 An elastic sheet 5 is fixed on the plate body 1. The elastic sheet 5 is located in the accommodating cavity 12 and above the fixed block 3. The elastic sheet 5 is fixed on the top inner wall of the accommodating cavity 12.

In this embodiment, the elastic sheet 5 is made of rubber.

[0035] The implementation principle of a fender capable of extending the service life in the embodiment of the present application is as follows:

[0036] When the car is traveling on an uneven road section, the raised part on the road section comes into contact with the extension plate 2, and the extension plate 2 moves under the push of the road surface to adapt to the ups and downs of the road section, thereby reducing the impact and subsequent damage between the fender and the road surface, which is beneficial to extending the service life of the fender; the mud, sand and stones thrown out by the rotation of the wheel enter the accommodating chamber 12 through the opening 13 and fall onto the fixed block 3, and the water is discharged through the through hole 14. Solid objects such as stones and gravel remain on the fixed block 3 to exert pressure on the extension plate 2, making it difficult for the extension plate 2 to reciprocate significantly under the bumps caused by the driving of the car, thereby reducing the wear between the extension plate 2 and the plate body 1, which is beneficial to further extending the service life of the fender, and can also reduce the sound emitted by the fixed block 3 hitting the plate body 1, thereby achieving noise reduction.

[0037] When the fixed block 3 moves upward, the deformation ability of the elastic sheet 5 is utilized to make the push block 6 abut against the inclined surface 4 and tilt along the inclined surface 4 toward the opening 13, thereby pushing the solid objects on the fixed block 3 toward the opening 13, so that the solid objects on the fixed block 3 slide along the inclined surface 4 toward the opening 13 and then separate from the fixed block 3. After the fixed block 3 falls back to the bottom of the accommodating chamber 12, the mud, sand and gravel thrown out by the rotation of the wheel will re-enter the accommodating chamber 12, thereby realizing the continuous renewal of the solid objects in the accommodating chamber 12 and reducing the situation where the movement of the fixed block 3 is hindered due to the hardening of mud and sand.

[0038] When muddy water is splashed onto the plate body 1 by the rotation of the wheel, the muddy water flows down along the surface of the plate body 1 and enters the accommodation cavity 12 through the second through hole 15 to moisten the solid matter in the accommodation cavity 12. The excess muddy water is discharged through the first through hole 14, thereby suppressing the hardening of the solid matter in the accommodation cavity 12.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
