[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 2The utility model provides an embodiment: an electric vehicle fender with a self-cleaning function, comprising a fender 1, the fender 1 is arranged in an arc shape, convenient for matching with a wheel hub 4, a side plate 2 for supporting is fixedly connected to the back of the fender 1, a shaft body 3 arranged in a horizontal state is installed through the middle of the side plate 2, a wheel hub 4 is arranged on the circumferential surface of the shaft body 3, and a cleaning mechanism is arranged inside the fender 1.

[0033] Reference Figure 3 , Figure 4 The cleaning mechanism includes a scraper 5 for cleaning the inner wall of the mudguard 1. A moving groove 6 is provided on the front of the side plate 2. The direction of the moving groove 6 is the same as the arc direction of the mudguard 1. The scraper 5 is slidably installed on the inner wall of the moving groove 6. The displacement of the scraper 5 is guided by setting the moving groove 6 so that the scraper 5 moves along the arc of the mudguard 1. A slider 7 is fixedly connected to the front of the scraper 5. A slide groove 8 is provided on the front of the mudguard 1. The slider 7 is slidably installed on the inner wall of the slide groove 8. The slider 7 is set to be L-shaped, and the end of the slider 7 away from the scraper 5 is set to be trapezoidal. The shape of the slide groove 8 matches the slider 7. The cooperation of the spring slider 7 and the slide groove 8 ensures that the scraper 5 will not fall off the inner wall of the mudguard 1 when it moves. The displacement of the scraper 5 is guided by setting the slider 7 to further improve the movement stability of the scraper 5.

[0034] Reference Figure 3 - Figure 5 The cleaning mechanism also includes a stepper motor 9, which can accurately control the rotation angle of its output shaft, conveniently adjust the rotation speed and rotation angle of its rotating shaft, and can be adjusted accordingly according to different needs to improve the accuracy of control. The stepper motor 9 is fixedly installed on the front side of the scraper 5, and the rear side of the output shaft of the stepper motor 9 is fixedly connected with a rotating shaft 10, which passes through and is rotatably installed on the inner wall of the scraper 5. The cleaning mechanism also includes a gear 11, which is arranged on the rear side of the scraper 5. The gear 11 is fixedly installed on the circumferential surface of the rotating shaft 10, and the inner wall of the fender 1 is fixedly connected with teeth 12. The number of teeth 12 is set to multiple, and multiple teeth 12 are arranged on the inner wall of the fender 1 in a ring-shaped and equidistant manner. The gear 11 is meshed with the teeth 12. Through the cooperation of the gear 11 and the teeth 12, when the gear 11 is displaced relative to the teeth 12, the gear 11 will also rotate.

[0035] Reference Figure 5A self-cleaning mechanism is provided on the left side of the scraper 5, and the self-cleaning mechanism includes a fixed plate 13 and a reciprocating screw 14. When the reciprocating screw 14 rotates, it drives the cleaning plate 16 to perform reciprocating linear motion in the axial direction of the reciprocating screw 14. The fixed plate 13 is fixedly installed on the left side of the scraper 5, and the reciprocating screw 14 penetrates and is rotatably installed on the inner wall of the fixed plate 13 to improve the stability of the reciprocating screw 14 when rotating. A cleaning plate 16 is slidably installed on the circumferential surface of the reciprocating screw 14. Since the soil is sticky, it will adhere to the surface of the scraper 5, affecting the subsequent cleaning effect. The soil adhered to the surface of the scraper 5 is scraped off by the displacement of the cleaning plate 16 to improve the cleaning effect. The right side of the cleaning plate 16 is fitted with the left side of the scraper 5. The self-cleaning mechanism also includes a gear 2 15, which is fixedly installed on the circumferential surface of the reciprocating screw 14, and the gear 2 15 is meshed with the teeth 12. A purification mechanism is provided inside the cleaning plate 16.

[0036] Reference Figure 5 , Figure 6 The purification mechanism includes a hose 17, and a detergent is installed inside the hose 17 to soften the soil and facilitate subsequent cleaning. It is a prior art. A threaded hole 18 is opened inside the cleaning plate 16, and the hose 17 is threadedly installed on the inner wall of the threaded hole 18 to improve the stability of the installation of the cleaning plate 16. The purification mechanism also includes a guide hole 19, which is opened inside the cleaning plate 16. The guide hole 19 is connected to the threaded hole 18. The detergent inside the hose 17 will be discharged from the guide hole 19 to the outside of the cleaning plate 16, thereby improving the scraping effect of the cleaning plate 16 on the soil.

[0037] Working principle: When in use, by starting the stepper motor 9, the stepper motor 9 works to rotate the shaft 10, and the rotation of the shaft 10 drives the gear 11 to rotate. The rotation of the gear 11 causes the scraper 5 to slide on the inner wall of the fender 1 through the action of the teeth 12. When the scraper 5 moves to the edge of the fender 1, the stepper motor 9 rotates in the opposite direction, causing the scraper 5 to move in the opposite direction. The reciprocating movement of the scraper 5 scrapes off the mud adhered to the inner wall of the fender 1 to ensure the normal rotation of the wheel hub 4.

[0038] When the scraper 5 is displaced on the inner wall of the fender 1, the movement of the scraper 5 will also drive the cleaning plate 16 and the reciprocating screw 14 to move together. The movement of the reciprocating screw 14 drives the gear 2 15 to move. The gear 2 15 rotates under the action of the teeth 12, causing the reciprocating screw 14 to rotate. The rotation of the reciprocating screw 14 causes the cleaning plate 16 to reciprocate in a straight line in the axial direction of the reciprocating screw 14. The displacement of the cleaning plate 16 scrapes off the dirt on the surface of the scraper 5 for a second time, thereby avoiding the dirt adhered to the surface of the scraper 5 from having an adverse effect on the cleaning effect of the scraper 5, thereby improving the cleaning effect of the scraper 5 on the inner wall of the fender 1.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
