Technical Field
[0001] This invention relates to the field of automotive parts technology, and in particular to a mudguard for autonomous vehicles. Background Technology
[0002] With the rapid development of automotive technology, automobiles, as a fast and convenient means of transportation, are increasingly gaining popularity across all sectors of society. Autonomous vehicles, also known as driverless cars, computer-driven cars, or wheeled mobile robots, are intelligent vehicles that achieve driverless operation through computer systems. As autonomous driving technology develops, the technology of components supporting autonomous vehicles is also continuously being upgraded. When a car is driving, the rotating wheels will kick up mud on the road surface and throw the mud out along the tangential directions during the rotation of the wheels. In order to prevent the mud kicked up by the wheels from dirtying the car and to prevent flying sand and stones from hitting the car body and damaging the protective paint, mudguards are usually installed behind the car wheels to block rainwater and sand splashed up by the wheels.
[0003] Existing mudguards are mainly made by rolling a single sheet of material using relevant processing equipment to form a mudguard with rounded ends and rounded sides. The mudguard is directly fixed to the vehicle body with bolts. The length and height of the pressed mudguard are fixed. After installation, the distance between the mudguard and the tire and the height of the ground are kept constant. Later, when the vehicle is driving autonomously, the mudguard with fixed dimensions is prone to scraping against the road surface when it is affected by uneven road conditions. This not only increases the vehicle's drag but also easily causes the mudguard to deform. In addition, mud and clay will adhere to the tires later. Since the distance between the mudguard and the tire remains constant, clay will easily accumulate, which will increase the friction between the tire and the mudguard, thus increasing the difficulty of driving. Summary of the Invention
[0004] The purpose of this invention is to provide a mudguard for autonomous vehicles, aiming to improve the existing mudguards. The existing mudguards, with their fixed distance from the tire and height from the ground, are prone to scraping against the road surface when the road surface changes unevenly. This not only increases vehicle drag but also easily causes mudguard deformation. Furthermore, mud and clay adhere to the tires later, and the constant distance between the mudguard and tire makes it easy for clay to accumulate, thus increasing the friction between the tire and the mudguard, and consequently increasing the difficulty of driving.

[0011] Furthermore, the mounting base is assembled onto the vehicle frame with bolts, and a vertical rod is fixed vertically upward on the top surface of the mounting base. The vertical rod passes vertically upward through the perforated strip on the lifting plate. A first electric telescopic rod is installed vertically upward on the top surface of the mounting base, and the top end of the first electric telescopic rod is fixed to the bottom surface of the perforated strip.
[0012] Furthermore, the first sludge scraper includes a sludge scraper shell and a first scraper. The sludge scraper shell is vertically disposed at the bottom end of the plate body, and screw holes are fixed vertically upward on both sides of the top surface of the sludge scraper shell. The screw holes are assembled in the screw holes of the sludge scraper shell by screws. The first scraper is horizontally adjustable inside the sludge scraper shell.
[0013] Furthermore, an adjusting screw is installed on the outer end face of the mud scraper plate with a horizontal thread passing through the inner end face, and the end of the adjusting screw is rotatably connected to the first scraper plate through a bearing. Multiple first scraper strips are horizontally fixed on the outer end face of the first scraper plate away from the mud scraper plate, and an insert rod is horizontally fixed on the outer end face of the first scraper plate near the mud scraper plate, and the insert rod is horizontally slidably installed through the outer end face of the mud scraper plate.
[0014] Furthermore, the second sludge scraper includes a sliding frame and a sliding groove plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] (1) During use, the mudguard can be adjusted horizontally and vertically on the mounting part to change the distance between the mudguard and the tire and the distance between the bottom of the mudguard and the ground. Thus, in autonomous driving, the distance between the mudguard and the tire and the distance between the bottom of the mudguard and the ground can be adjusted according to the needs of the ground and the clay adhering to the tire, making it suitable for driving in different terrains.
[0018] (2) When in use, start the second motor to drive the gear to rotate, thereby driving the rack on the plate and the gear to move horizontally, thereby driving the horizontal bar on the bracket on the plate to slide horizontally on the sliding hole plate on the lifting plate, adjusting the distance between the tire and the plate, and adapting to different terrain driving needs.
[0019] (3) During use, the fixed seat is assembled on the vehicle frame with bolts. The first electric telescopic rod is started to push the lifting plate vertically on the vertical rod to lift it vertically. This makes it convenient to adjust the height of the plate from the ground according to the driving needs of the terrain later, so as to avoid the plate from rubbing against the ground, increasing driving resistance, and causing the plate to deform, which would affect the mud-blocking effect.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a mudguard for an autonomous vehicle includes a mudguard 1, a mounting component 2, a first mud scraper 3, and a second mud scraper 4. The mudguard 1 includes a plate body 11, with the mounting component 2 disposed on the outer end face of the plate body 11, and the plate body 11 is fixed to the vehicle frame by the mounting component 2. The first mud scraper 3 is vertically and detachably mounted on the bottom end of the plate body 11, and the second mud scraper 4 is horizontally and detachably mounted on the top end of the plate body 11. In use, the mudguard 1 can be adjusted horizontally and vertically on the mounting component 2 to change the distance between the mudguard 1 and the tire and the distance between the bottom end of the mudguard 1 and the ground. Thus, in autonomous driving, the distance between the mudguard 1 and the tire and the distance between the bottom end of the mudguard 1 and the ground can be adjusted according to the needs of the ground and the clay adhering to the tire, making it suitable for driving in different terrains.
[0031] Please see Figure 2 and Figure 3 The bottom two vertical end faces of the plate 11 are provided with assembly screw grooves 111, and the inner middle of the plate 11 is provided with a material-pulling rod 12. Both ends of the material-pulling rod 12 are provided through the two end faces of the plate 11 via bearings. A first motor 14 is horizontally fixed on one end face of the plate 11, and the output end of the first motor 14 is connected to one end shaft of the material-pulling rod 12. Multiple rotating wheels 13 are horizontally fixed on the outer circumference of the material-pulling rod 12, and multiple scraper blades 131 are evenly and vertically fixed on the outer circumference of the rotating wheels 13. In use, the first motor 14 drives the material-pulling rod 12 to rotate on the plate 11. The rotation of the material-pulling rod 12 drives the multiple rotating wheels 13 to rotate. The multiple scraper blades 131 on the rotating wheels 13 are used to loosen the clay adhering to the plate 11 and the tire, so that the clay between the plate 11 and the tire can be removed, reducing the friction of the clay on the tire.
[0032] Please see Figure 2 , Figure 3 and Figure 4The mounting component 2 includes a bracket 21 and a lifting component 24. The bracket 21 is fixed to the outer end face of the plate 11, and horizontal bars 22 are horizontally fixed on both sides of the top surface of the bracket 21 away from the plate 11. A rack 23 is horizontally fixed in the middle of the top surface of the bracket 21 away from the plate 11. The lifting component 24 is provided on the vertical end face of the bracket 21. The lifting component 24 includes a lifting plate 241 and a fixed seat 245. The lifting plate 241 is vertically arranged, and a sliding hole plate is fixed on the top surface of the lifting plate 241. The sliding hole plate on the lifting plate 241 is slidably engaged with the horizontal bars 22. The bottom of one vertical end face of the lifting plate 241 is... A perforated strip 244 is horizontally fixed, and a fixed seat 245 is horizontally and vertically adjustable on the perforated strip 244. A second motor 242 is horizontally fixed on one vertical end face of the lifting plate 241, and a gear 243 is fixed at the output end of the second motor 242. The gear 243 meshes with the rack 23. When in use, the second motor 242 is started to drive the gear 243 to rotate, thereby driving the rack 23 on the plate 11 and the gear 243 to move horizontally. This causes the horizontal rod 22 on the bracket 21 on the plate 11 to slide horizontally on the sliding perforated plate on the lifting plate 241, adjusting the distance between the tire and the plate 11 to meet different terrain driving needs.
[0033] Please see Figure 2 , Figure 3 and Figure 4 The mounting base 245 is assembled onto the vehicle frame by bolts 248. A vertical rod 246 is vertically fixed upward on the top surface of the mounting base 245, and the vertical rod 246 is vertically inserted through the perforated strip 244 on the lifting plate 241. A first electric telescopic rod 247 is vertically installed upward on the top surface of the mounting base 245, and the top end of the first electric telescopic rod 247 is fixed to the bottom surface of the perforated strip 244. In use, the mounting base 245 is assembled onto the vehicle frame by bolts 248. The first electric telescopic rod 247 is activated to vertically push the lifting plate 241 to vertically lift and lower on the vertical rod 246. This allows for easy vertical adjustment of the height of the plate 11 from the ground according to the terrain and driving needs, avoiding friction between the plate 11 and the ground, which would increase driving resistance and cause deformation of the plate 11, thus affecting the mud-blocking effect.
[0034] Please see Figure 2 and Figure 7The first scraper component 3 includes a scraper shell plate 31 and a first scraper 34. The scraper shell plate 31 is vertically disposed at the bottom end of the plate body 11, and screw holes 32 are vertically fixed on both sides of the top surface of the scraper shell plate 31. The screw holes 32 are assembled into the screw holes 32 of the scraper shell plate 31 by screws. The first scraper 34 is horizontally adjustable inside the scraper shell plate 31. An adjusting screw 33 is installed on the outer end face of the scraper shell plate 31 with a horizontal thread passing through the inner end face. The end of the adjusting screw 33 is rotatably connected to the first scraper 34 through a bearing. Multiple first scraper strips 36 are horizontally fixed on the outer end face of the first scraper 34 away from the scraper shell plate 31. A rod 35 is horizontally fixed on the outer end face of the plate 34 near the mud scraper plate 31. The rod 35 slides horizontally through the outer end face of the mud scraper plate 31. During use, depending on the road surface, screw holes 32 are vertically fixed on both sides of the top surface of the mud scraper plate 31. The screw holes 32 are assembled into the screw holes 32 of the mud scraper plate 31 by screws, thus completing the assembly connection between the mud scraper plate 31 and the plate body 11. At the same time, according to the terrain and the need for clay adhering to the tire, the adjusting screw 33 is adjusted to horizontally push the first scraper plate 34 closer to the tire, adjust the mud scraping distance, and prevent too much clay from the tire from being rolled into the plate body 11 and the tire, thus increasing driving resistance.
[0035] Please see Figure 2 and Figure 6 The second sludge scraper 4 includes a sliding frame 41 and a sliding groove plate 42. The sliding frame 41 is horizontally fixed to the top of the plate 11, and the sliding groove plate 42 is horizontally slidably installed in the sliding frame 41. A second electric telescopic rod 48 is horizontally fixed to one end of the top surface of the sliding frame 41 away from the plate 11, and the other end of the second electric telescopic rod 48 is fixed to the top surface of the sliding groove plate 42. The second electric telescopic rod 48 is used to horizontally drive the sliding groove plate 42 to slide on the sliding frame 41, changing its sludge scraping position. The bottom surface of the sliding groove plate 42 is open, and an airbag 43 is fixed inside the sliding groove plate 42. The bottom surface of the airbag 43 is open. A second scraper 44 is fixed horizontally at the top, and multiple scraper strips 45 are evenly and vertically fixed on the bottom surface of the second scraper 44. An air pipe 47 is fixed vertically upward through the top surface of the slide plate 42 at the top of the airbag 43, and an air pump 46 is installed on the air pipe 47. During use, according to the need to scrape mud off the tire, the air pump 46 is started to drive air through the air pipe 47 into and out of the airbag 43, causing the airbag 43 to contract or expand, which drives the second scraper 44 to move vertically closer to or away from the tire, changing the distance between the tire and the second scraper 4, and using the scraper strips 45 to scrape off the clay adhering to the tire.
[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
