Description

A vehicle and its fender

technical field

The invention relates to the field of vehicle devices, in particular to a vehicle and its fender.

Background technique

When the vehicle is running, the pressure under the chassis is higher than the pressure on the outside of the vehicle body, so that the airflow under the chassis flows to the outside of the vehicle body. At the same time, the rotation of the tires lifts up the muddy water on the ground, and the muddy water on the ground flows outward under the chassis. It is easy to adhere to the surface of the car body, so the rear of the vehicle tires is usually equipped with fenders to prevent muddy water or other sundries brought up by the rotation of the tires, and try to keep the vehicle clean without affecting the vision of the vehicles behind. In order to achieve a better blocking effect, the fenders are usually enlarged as much as possible, but the enlarged fenders will increase the air resistance and increase the fuel consumption of the vehicle. At present, the above-mentioned problems are solved by opening diversion holes on the fender, for example, a Chinese patent application with the publication number CN102530100A and the publication date of 2012.07.04 discloses a downwind slit fender for vehicles, The middle part of the fender body of the fender forms a radian backwards, and the slits are evenly distributed on the flanging downwind, and the flanging downwind slits are the diversion channels. And the flanging and downwind slits increase the strength. After the wind passes through the fender flanging and downwind slits, the wind direction turns to blow downwards, reducing wind resistance. Since the pressure under the chassis is higher than the pressure outside the vehicle body during the running of the vehicle, the sludge passing through the diversion holes of the sludge plate will still splash on the vehicle body under the action of the airflow flowing outward under the chassis, and the protection effect is poor. In addition, the front projection area of the fender is not substantially reduced, and the effect of reducing wind resistance is poor.

Detailed ways

Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

The specific embodiment of vehicle of the present invention, as shown in Figure 1 and Figure 2, vehicle comprises vehicle frame 1, the wheel 2 that is arranged on vehicle frame 1 and is fixed on vehicle frame 1 and is in the fender 3 of wheel 2 rear side , The fender 3 is provided with an L-shaped connecting plate 32 fixedly connected with the vehicle frame.

In this embodiment, the L-shaped connecting plate 32 is made of elastic material so that the L-shaped connecting plate constitutes an elastic connecting piece disposed on the fender. After the fender is subjected to external force, the L-shaped connecting plate can produce a certain elastic deformation to prevent accidental damage to the fender. As shown in FIG. 4 , the L-shaped connecting plate 32 is provided with a mounting hole 321 , and the upper part of the L-shaped connecting plate 32 is riveted with the vehicle frame 1 profile through the mounting hole 321 . The lower part of the L-shaped connecting plate 32 is fixedly connected with the upper mounting hole of the fender 3 through the mounting hole 321 with bolts.

As shown in Figures 2 and 3, the fender 3 has a front side facing the wheel and a rear side facing away from the wheel. 1, the flow guide channel 311 extends from the front side of the fender to the rear side. In this embodiment, the fender 3 includes vertical partitions 314 arranged at intervals, and also includes transverse partitions 315 arranged at intervals. Form quadrilateral guide straight holes, guide channel 311 is made of quadrangular guide straight holes, and vertical partition 314 is inclined toward the inner side of vehicle frame from front to back so that the airflow through guide channel is blown to the inner side of vehicle frame. The transverse partition 315 is inclined from top to bottom from front to rear so that the air guide channel 311 guides the airflow to blow to the inside of the vehicle frame 1 and at the same time guides the airflow to blow to the bottom of the vehicle frame 1 .

The projections of the inlet and outlet of the guide channel 311 in the forward and backward direction have overlapping portions, which reduces the projected area of the fender in the forward and backward direction and further reduces air resistance. In other embodiments, the guide channel can be formed by a triangular direct guide hole, a polygonal direct guide hole or a circular direct guide hole arranged on the fender. Of course, a plurality of guide channels on the fender can also be made of Straight diversion holes of different shapes are formed. In this embodiment, the fender 3 is integrally formed, and the fender body is made of plastic material. In other embodiments, the horizontal partition and the vertical partition can be arranged in layers along the thickness direction of the fender and connected by bolts or Welded together, the fender can also be made of fiberglass and other materials that meet the strength and wear resistance.

The guide channel 311 is inclined from top to bottom from front to back and is inclined towards the inner side of the frame from front to rear. The angle of inclination towards the inside of the frame is 45 degrees. In other embodiments, the inclination angle of the guide channel from front to rear and from top to bottom may be 10° to 80°, and the inclination angle of the guide channel from front to rear toward the inner side of the frame may be 10° to 80°.
