Detailed implementation manners

[0016] The present invention can be explained in detail through the following embodiments, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Please refer to Figures 1-6 , this embodiment provides a technical solution: a mudguard for an automobile that is easy to clean, including a frame 1. Two driving rollers 8 are rotatably installed inside the frame 1. A conveyor belt 4 is drivingly connected between the two driving rollers 8. A servo motor 2 is installed on the side of the frame 1. The output shaft of the servo motor 2 is fixedly connected to one of the driving rollers 8. A heating unit 3 is installed on the conveyor belt 4. A scraper 6 is fixed at the position corresponding to the back of the conveyor belt 4 on the frame 1. The scraper 6 is in contact with the outer surface of the conveyor belt 4. The servo motor 2 is electrically connected to the vehicle-mounted controller of the automobile.

[0018] It further includes a tooth groove 10 and teeth 11. The teeth 11 are evenly fixed on the driving roller 8. The tooth grooves 10 are evenly formed on the conveyor belt 4. The teeth 11 are meshed with the tooth grooves 10. The transmission stability of the conveyor belt 4 is increased through meshing transmission. The output shaft of the servo motor 2 drives the driving roller 8 to rotate. The two driving rollers 8 are drivingly connected through the conveyor belt 4. The conveyor belt 4 is used as a mudguard. The dirty part on the conveyor belt 4 moves to the position of the scraper 6. The dirt on the conveyor belt 4 is scraped off by the scraper 6. It avoids the trouble of the need for the scraper 6 to reciprocate to clean the dirt, has a good cleaning effect, and is convenient to use.

[0019] It further includes a rail groove 9. The rail groove 9 is formed on the frame 1. The edge of the conveyor belt 4 extends into the inside of the rail groove 9 and is in contact and sliding connection with the rail groove 9. The rail groove 9 is used to plan the running path of the conveyor belt 4, so as to meet the mudguard requirement.

[0020] The heating unit 3 includes a warm air duct 31 and a heat conduction pipe 34. The heat conduction pipe 34 is evenly filled inside the conveyor belt 4. The end of the heat conduction pipe 34 is in internal communication with the track groove 9. The warm air duct 31 is fixed to the side of the frame 1 and is in internal communication with the track groove 9. The warm air duct 31 is in communication with the warm air system of the vehicle. The heating unit 3 further includes a first through hole 32 and a second through hole 33. The first through hole 32 is opened on the inner surface of the conveyor belt 4, and the second through hole 33 is opened on the heat conduction pipe 34. The first through hole 32 and the second through hole 33 are in mutual communication. When encountering freezing weather, the warm air system of the vehicle inputs hot air into the track groove 9 through the warm air duct 31. The hot air in the track groove 9 enters the heat conduction pipe 34, and the conveyor belt 4 is heated through the heat conduction pipe 34 to remove ice. At the same time, the hot air in the heat conduction pipe 34 enters the inside of the conveyor belt 4 through the first through hole 32 and the second through hole 33, so as to heat the conveyor belt 4 as a whole. It is convenient to clean the ice layer, avoiding the trouble of manual cleaning, saving time and effort. It uses the warm air system of the vehicle as the heating source without adding new equipment, thus reducing the equipment cost.

[0021] It further includes a vibration motor 7. The vibration motor 7 is installed on the side of the scraper 6. The vibration motor 7 is electrically connected to the vehicle-mounted controller of the vehicle. The vibration motor 7 drives the scraper 6 to vibrate, and the vibration of the scraper 6 causes the dirt on its surface to vibrate and fall off, thus ensuring the cleaning effect of the scraper 6.

[0022] It further includes a diversion groove 5. The diversion grooves 5 are evenly opened on the surface of the conveyor belt 4. The diversion grooves 5 are arranged along the conveying direction of the conveyor belt 4. The diversion grooves 5 are used to increase the drainage capacity of the conveyor belt 4.

[0023] It further includes a hydrophobic coating. The hydrophobic coating is a hydrophobic coating containing SiO2 nanoparticles. The hydrophobic coating is sprayed on the outer surface of the conveyor belt 4. The hydrophobic coating is used to reduce the adhesion ability of stains on the surface of the conveyor belt 4, thus reducing the working burden of the scraper 6.

[0024] The working principle of a fender for automobiles that is convenient to clean provided by the present invention is as follows: The output shaft of the servo motor 2 drives the driving roller 8 to rotate. The two driving rollers 8 are driven by a conveyor belt 4 therebetween. The conveyor belt 4 is used as a fender. The dirty part on the conveyor belt 4 moves to the position of the scraper 6, and the dirt on the conveyor belt 4 is scraped off by the scraper 6. The vibration motor 7 drives the scraper 6 to vibrate, and the vibration of the scraper 6 causes the dirt on its surface to vibrate and fall off. When encountering icy weather, the warm air system of the automobile inputs hot air into the track groove 9 through the warm air duct 31. The hot air in the track groove 9 enters into the heat conduction pipe 34, and the conveyor belt 4 is heated through the heat conduction pipe 34 to remove ice. At the same time, the hot air in the heat conduction pipe 34 enters the inner side of the conveyor belt 4 through the first through hole 32 and the second through hole 33, so as to heat the conveyor belt 4 as a whole. The diversion groove 5 is used to increase the drainage capacity of the conveyor belt 4, and the hydrophobic coating is used to reduce the adhesion ability of stains on the surface of the conveyor belt 4.
