The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0033] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0034] In this text, the first direction X, the second direction Y, and the third direction Z intersect each other pairwise. For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other pairwise.

[0035] This disclosure provides a vehicle, which can be a new energy vehicle, a hybrid vehicle, a gasoline vehicle, or other types of vehicle. The vehicle may include a body, a chassis, and wheels. The chassis is connected to both the body and the wheels. See also... Figure 1 The vehicle body may include a main body, wheel arches 2, wheel fenders 3, and fenders 1. Wheel arches 2 are connected to the main body and wrapped around the wheels to prevent debris from splashing up and damaging the vehicle body. There is a gap between the wheel arches 2 and the wheels. Wheel fenders 3 are connected to the outer side of the wheel arches 2 away from the main body, and an air duct exists between the wheel arches 3 and the wheel arches 2. Fenders 1 are connected to the wheel arches 3 and the main body via clips and bolts. Fenders 1 have a vehicle air duct structure with an air guide channel 14, which connects to the air duct. Thus, during vehicle operation, airflow can pass sequentially through the air duct and the air guide channel 14, reducing wind resistance and wind noise, and increasing the vehicle's range.

[0036] In one embodiment of this disclosure, see Figures 2-5 The vehicle's air duct structure includes an outer panel 11 and an inner panel stacked along a first direction X. The inner panel has an air guide channel 14 extending along a second direction Y. The inner panel includes a first inner panel 12 and a second inner panel 13 stacked on top of the outer panel 11 along the first direction X. The first inner panel 12 and the second inner panel 13 form at least a portion of the air guide channel 14, and the first direction X and the second direction Y intersect. Thus, by forming at least a portion of the air guide channel 14 through the first inner panel 12 and the second inner panel 13, the vehicle can exhaust air through the air guide channel 14 during vehicle operation, thereby reducing wind resistance during vehicle operation, which helps to improve the vehicle's driving range and reduce energy consumption. The outer panel 11 can provide protection for the inner panel, making the vehicle's shape more aesthetically pleasing, while also increasing the structural strength of the fender 1 and improving the vehicle's reliability.

[0037] In one embodiment of this disclosure, the outer panel 11, the first inner panel 12, and the second inner panel 13 are connected to each other in pairs. For example, the outer panel 11 and the first inner panel 12 can be connected by piercing welding and riveting, and the outer panel 11 and the second inner panel 13 can also be connected by piercing welding and riveting. The first inner panel 12 and the second inner panel 13 can be connected by riveting to improve the connection strength of the fender 1, meet the stress requirements during wading, and improve the reliability of the vehicle. At the same time, it avoids the generation of welding marks and injection molding shrinkage marks, thereby improving the appearance of the vehicle.

[0038] In one embodiment of this disclosure, the first inner plate 12 and the second inner plate 13 may form a portion of the air guide channel 14. In other embodiments of this disclosure, the first inner plate 12 and the second inner plate 13 may form the entire area of ​​the air guide channel 14.

[0039] In one embodiment of this disclosure, see Figure 3 , Figure 5 The area of ​​the air guide channel 14 decreases sequentially along the Z-direction. This increases the inlet area of ​​the air guide channel 14, effectively increasing the exhaust volume and further reducing wind resistance during vehicle operation.

[0040] In one embodiment of this disclosure, see Figures 2-5 The first inner panel 12 includes an integrally connected base plate 121 and a baffle 122. The base plate 121 is fitted to the outer panel 11, and the baffle 122 is located on the inlet side of the air guide channel 14, through which the air guide channel 14 passes. Thus, placing the baffle 122 between the base plate 121 and the second inner panel 13 provides support for both the base plate 121 and the second inner panel 13, which is beneficial for the installation of the air guide channel 14 and improves the structural strength.

[0041] In one embodiment of this disclosure, the side of the fender 1 closest to the wheel is curved. For example, the side of the fender 1 closest to the wheel can be arc-shaped to facilitate adaptation to the wheel.

[0042] In one embodiment of this disclosure, see Figures 2-5 At least one air guide plate 123 is provided within the air duct 14. For example, the number of air guide plates 123 can be multiple, such as one, two, three, four, five, six, or seven. The air guide plate 123 is connected to the baffle 122, and the air guide plate 123 divides at least a portion of the air duct 14 located within the baffle 122 into multiple sub-channels along a third direction Z. In this way, the air duct 14 can be divided into multiple sub-channels by the air guide plate 123, so that the air in the air duct 14 is discharged in a certain direction, which is compatible with the streamlined structure of the vehicle body and further reduces wind resistance during vehicle operation. In addition, it also improves the aesthetics of the fender 1.

[0043] In one embodiment of this disclosure, at least a portion of the air guide plate 123 located within the baffle 122 is integrally formed with the baffle 122. This saves process steps and reduces costs.

[0044] In one embodiment of this disclosure, the baffle 122 has a notch, and at least a portion of the air guide plate 123 located within the baffle 122 is inserted into the notch. This allows the air guide plate 123 to be detachably connected to the baffle 122, facilitating the maintenance, cleaning, and replacement of the air guide plate 123.

[0045] In one embodiment of this disclosure, multiple air guide plates 123 can be inclined in the same direction, and the air guide plates 123 can rotate within the air guide channel 14 about the straight line containing the first direction X, so as to adjust the angle of the air guide plates 123 to a suitable angle to suit the air guide mode of different intersections. The angle adjustment of the air guide plates 123 can be automatic, such as by adjusting through a motor transmission mechanism, or it can be manual.

[0046] In one embodiment of this disclosure, the wind deflector 123 may be extended from the baffle 122 along the second direction Y to improve the stability during the wind direction guidance process.

[0047] In one embodiment of this disclosure, the air guide plate 123 can pass through the second inner plate 13, and the second inner plate 13 has a cavity for the air guide plate 123 to pass through. In this way, when installing the second inner plate 13 and the first inner plate 12, it is beneficial to quickly position the second inner plate 13 and improve the installation efficiency.

[0048] In one embodiment of this disclosure, see Figure 3 , Figure 5 , Figure 6The sidewall of the area of ​​the air guide channel 14 located within the baffle 122 includes multiple air guide surfaces, and each air guide surface includes at least a first air guide surface 141 and a second air guide surface 142 distributed along the first direction X. The first air guide surface 141 and the second air guide surface 142 are bent in opposite directions. In this way, the first air guide surface 141 and the second air guide surface 142 are bent in opposite directions, which increases the area of ​​the inlet of the air guide channel 14, which can further improve the exhaust effect of the air guide channel 14, thereby reducing the wind resistance during vehicle movement.

[0049] In one embodiment of this disclosure, each air guide surface may further include a third air guide surface and a fourth air guide surface. The third air guide surface and the fourth air guide surface are arranged opposite to each other. One end of the first air guide surface 141 and one end of the second air guide surface 142 are connected through the third air guide surface. The other end of the first air guide surface 141 and the other end of the second air guide surface 142 are connected through the fourth air guide surface. The first air guide surface 141, the second air guide surface, the third air guide surface and the fourth air guide surface form a closed entrance to the air guide channel 14.

[0050] In one embodiment of this disclosure, see Figure 2 , Figure 3 The second inner plate 13 includes a plate body 131 and a boss 132 disposed on the plate body 131. The plate body 131 is attached to the baffle 122, and the plate body 131, the boss 132, and the bottom plate 121 form a part of the air guide channel 14. In this way, the boss 132 can limit the area of ​​the air guide channel 14, preventing the air velocity from being too slow due to the area of ​​the air guide channel 14 being too large, thereby affecting the exhaust efficiency.

[0051] In one embodiment of this disclosure, see Figure 2 The orthographic projection of the panel 131 on the first plane is located within the orthographic projection of the outer panel 11 on the first plane. A portion of the air duct 14 is exposed on the panel 131. The first plane is the plane formed by the second direction Y and the third direction Z. This makes the fender more aesthetically pleasing.

[0052] In one embodiment of this disclosure, see Figure 2 , Figure 3 The boss 132 has a mounting area 133 for mounting an image acquisition device. The mounting area 133 has a recessed portion, which is recessed towards the side of the plate 131 away from the boss 132. The image acquisition device is mounted in the recessed portion. The base plate 121 and the outer plate 11 are configured to expose at least the mounting area 133. In this way, an image acquisition device can be mounted on the fender 1, and the image acquisition device can capture images of the vehicle's surroundings, which is beneficial for the vehicle's intelligent driving.

[0053] In one embodiment of this disclosure, see Figure 4 , Figure 5The first inner panel 12 also includes a connecting plate 124, which is integrally connected to the bottom plate 121 along the third direction Z and to the baffle 122. The connecting plate 124 is connected to the outer panel 11 by riveting and piercing welding. There is a notch 125 between the connecting plate 124 and the bottom plate 121. The second inner panel 13 has a connecting part that passes through the notch 125 and connects to the outer panel 11. In this way, the connection strength between the second inner panel 13 and the outer panel 11 is improved by connecting the connecting part through the notch 125, thereby improving the reliability of the fender 1.

[0054] In one embodiment of this disclosure, the vehicle body has a plastic bracket and sheet metal parts, and the fender 1 has a connector, which can be a plastic clip. The fender 1 is connected to the plastic bracket and sheet metal parts respectively through the connector, so that the fender 1 can be installed on the vehicle body.
