[0002] In the latest national standard of China, "Terms and Definitions for the Types of Automobiles and Trailers" (GB / T 3730.1-2001), an automobile is defined as follows: a vehicle driven by power, having 4 or more wheels and non-railborne, mainly used for: carrying passengers and / or goods; towing vehicles carrying passengers and / or goods; special purposes.
[0003] An automobile fender is a plate structure installed behind the outer frame of a wheel, usually made of high-quality rubber material. The automobile fender can effectively block the mud splashed during the driving of the automobile.
[0004] During the rolling process of the tire and the ground when the vehicle is running, due to the presence of dust between the tire and the ground, the gas flow generated by the vehicle driving and the extrusion deformation of the inner cavity of the tire tread cause air explosion, which ultimately results in rolling dust. Rolling dust is an important factor in vehicle dust. Therefore, those skilled in the art have provided an automobile fender to solve the problems raised in the above background art. Summary of the Utility Model
[0005] The purpose of the utility model is to provide an automobile fender to solve the technical problems raised in the background art.
[0006] To achieve the above purpose, the specific technical solution of the utility model is as follows: an automobile fender, including an upper baffle, a front baffle is arranged at the front end of the upper baffle, a rear baffle is arranged at the rear end of the upper baffle, side baffles detachably connected to the upper baffle are arranged on both the left and right sides of the upper baffle, a tail plate is rotatably connected to the bottom of the rear baffle through a rotating shaft, an elastic telescopic rod is rotatably connected to the back of the tail plate through a rotating shaft, a U-shaped seat is arranged on the back of the rear baffle, the top end of the elastic telescopic rod is rotatably connected to the U-shaped seat through a rotating shaft, and a brush strip is arranged on the inner wall of the tail plate.
[0007] Preferably, the upper baffle, the front baffle and the rear baffle are of an integral structure, and the front baffle and the rear baffle are of an arc structure.
[0008] Preferably, a U-shaped fixing frame is arranged on the upper surface of the upper baffle, mounting holes are arranged on the upper surfaces of both ends of the fixing frame, and a plurality of equally spaced long slots are arranged on the upper surface of the fixing frame.
[0009] Preferably, three second bumps are arranged on the side wall of the side baffle in an orderly manner, and one first bump corresponding to the second bump is arranged on the side walls of the front baffle and the rear baffle. Studs are arranged at the middle parts of the left and right side walls of the fixing frame and on the surfaces of the first bumps. An oblong hole is arranged on the surface of the second bump, and the end of the stud extends to the outside of the oblong hole and is threadedly connected with a nut.
[0010] Preferably, the distance between the two side baffles is greater than the width of the tire.
[0011] Preferably, a plurality of brush strips are provided, and there is a gap between every two adjacent brush strips.
[0012] Preferably, the bottom of the tail plate is lower than the bottom of the front baffle.
[0013] The mudguard for an automobile of the present utility model has the following advantages:
[0014] 1. In the present utility model, by making the length of the front baffle shorter than the sum of the lengths of the rear baffle and the tail plate, the pressure in the front part of the wheel well is higher than that in the rear part. The relatively clean oncoming air flow of the vehicle flows backward along the upper surface of the wheel, driving the particulate matter remaining on the tire surface to accumulate on the rear baffle, and at the same time playing a role in cleaning the tire surface and reducing the dust in the front part of the wheel well. The rear baffle and the tail plate isolate the interaction between the eddy current behind the rear baffle and the tail plate and the air flow below the rear of the wheel, which can effectively reduce the dust. The side baffles are respectively arranged inside and outside the tire to reduce the air flow area, and the air flow containing dust is enclosed in the wheel well, which is beneficial to its post-treatment. By adopting a tail plate with brush strips on the surface, the kinetic energy of the air flow containing particulate matter will be greatly attenuated when it enters the area of the brush strips. Under the action of inertia, part of the air is separated from the particulate matter and stored in the tail plate, which can be washed off later, and other particulate matter will slide downward along the surface of the brush strips, reducing the energy of being lifted.
[0015] 2. In the present utility model, through the cooperation between the elastic telescopic rod and the tail plate and the rear baffle, when being collided by an obstacle, the tail plate will be lifted upward to avoid damage to the components. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an automobile fender of the utility model in conjunction with the accompanying drawings.
[0027] like Figures 1-3 As shown, a car fender of the utility model comprises an upper fender 1, a front fender 2 is arranged at the front end of the upper fender 1, a rear fender 3 is arranged at the rear end of the upper fender 1, the upper fender 1, the front fender 2 and the rear fender 3 are an integrated structure, and the front fender 2 and the rear fender 3 are arc-shaped structures, the left and right sides of the upper fender 1 are provided with side fenders 6 detachably connected thereto, the spacing between the two side fenders 6 is greater than the width of the tire, the bottom of the rear fender 3 is rotatably connected to a tail plate 4 through a rotating shaft, the bottom of the tail plate 4 is lower than the bottom of the front fender 2, the back of the tail plate 4 is rotatably connected to an elastic telescopic rod 11 through a rotating shaft, the back of the rear fender 3 is provided with a U-shaped seat 10, the top of the elastic telescopic rod 11 is rotatably connected to the U-shaped seat 10 through a rotating shaft, and the inner wall of the tail plate 4 is provided with a brush strip 9, a plurality of brush strips 9 are provided, and there is a spacing between each adjacent two brush strips 9.
[0028] The upper surface of the upper baffle 1 is provided with a fixing frame 5 of a U-shaped structure, and the upper surfaces of both ends of the fixing frame 5 are provided with mounting holes, and the upper surface of the fixing frame 5 is provided with a plurality of long strips distributed at equal intervals. The upper baffle 1 can be fastened to the frame by setting the mounting holes on the fixing frame 5. The side wall of the side baffle 6 is provided with three orderly distributed second protrusions 8, and the side walls of the front baffle 2 and the rear baffle 3 are each provided with a first protrusion 7 distributed corresponding to the second protrusion 8. Studs 12 are provided in the middle of the left and right side walls of the fixing frame 5 and on the surface of the first protrusion 7. The surface of the second protrusion 8 is provided with an oblong hole, and the end of the stud 12 extends to the outside of the oblong hole and is threadedly connected with a nut. Through the setting of the first protrusion 7 and the second protrusion 8, and under the action of the stud 12, the side baffle 6 is easy to install and disassemble.
[0029] Under the drastic change of the velocity gradient perpendicular to the road surface in the wheel well and the disturbance of the air, particulate matter is lifted and collided, and then overflows from both sides and the rear of the wheel well, moving and migrating towards the low-pressure area, causing dust. By making the length of the front baffle 2 shorter than the sum of the lengths of the rear baffle 3 and the tailboard 4, the pressure in the front part of the wheel well is higher than that in the rear part. The relatively clean oncoming air flow of the vehicle flows backward along the upper surface of the wheel, driving the particulate matter remaining on the tire surface to accumulate on the rear baffle 3, while playing a role in cleaning the tire surface and reducing the dust in the front part of the wheel well. The rear baffle 3 and the tailboard 4 isolate the interaction between the eddy current behind the rear baffle 3 and the tailboard 4 and the air flow under the rear of the wheel, which can effectively reduce dust. The channel for the air flow to flow out of the wheel well is also an important part of dust generation. Reducing its channel area and enclosing the air flow containing dust in the wheel well as much as possible is beneficial for its subsequent treatment. Therefore, side baffles 6 are respectively arranged inside and outside the tire to reduce the air flow area. To reduce the velocity of the air flow containing particulate matter in the wheel well and separate and accumulate the particulate matter from the air, the tailboard 4 with brush strips 9 on its surface is adopted. When the air flow containing particulate matter enters the area of the brush strips 9, its kinetic energy will be greatly attenuated. Under the action of inertia, part of the air is separated from the particulate matter and stored in the tailboard 4, which can be washed off later. Other particulate matter will slide downward along the surface of the brush strips 9, reducing the energy of lifting. When collided by an obstacle, under the action of the elastic telescopic rod 11, the tailboard 4 will be lifted upward to avoid damage to the components.
