Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of vehicles, in particular to a front wheel wind deflector and a vehicle. BACKGROUND

[0002] Wind resistance is an important component of vehicle driving resistance, and reducing wind resistance is one of the means to reduce energy consumption and increase driving range of vehicles. In order to reduce the wind resistance during vehicle driving, a front wheel wind deflector is generally arranged in front of the front wheel. In the related art, when the airflow flows along the front wheel wind deflector to the rear end of the front wheel wind deflector, it is easy to be rolled into the wheel cavity by the rotating front wheel, resulting in an increase in the airflow in the wheel cavity of the front wheel, so that the wind resistance during vehicle driving cannot be further reduced. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the present disclosure is to provide a front wheel wind deflector and a vehicle to solve the technical problems existing in the related art.

[0004] In order to achieve the above-mentioned purpose, according to a first aspect of the present disclosure, a front wheel wind deflector is provided, comprising:

[0005] a front wheel wind deflector body for being mounted on a vehicle body and located in front of a front wheel, a lower surface of the front wheel wind deflector body being a first flow guide surface, the first flow guide surface extending downwardly in a direction close to the front wheel;

[0006] an extension plate arranged at a rear end of the front wheel wind deflector body, a lower surface of the extension plate being a second flow guide surface connected with the first flow guide surface, the second flow guide surface extending downwardly in a direction close to the front wheel, and an included angle a of the second flow guide surface with respect to a horizontal direction being greater than an included angle y of the first flow guide surface with respect to the horizontal direction.

[0007] Optionally, the first flow guide surface is a convex arc surface arranged with a downward direction, and the second flow guide surface is a concave arc surface arranged with an upward direction.

[0008] Optionally, a radius of curvature of the first flow guide surface is greater than a radius of curvature of the second flow guide surface.

[0009] Optionally, the first flow guide surface and the second flow guide surface are connected by a circular arc transition.

[0010] Optionally, the extension plate extends along a length direction of the rear end of the front wheel wind deflector body, so that the extension plate can be engaged with the entire rear end of the front wheel wind deflector body.

[0011] Optionally, an angle difference between the included angle y and the included angle a is 10°-20°.

[0012] Optionally, the second flow guide surface has a downward distance L in the vertical direction of 5mm-20mm.

[0013] Optionally, a tangent direction of an end of the first flow guide surface intersects the front wheel, and a tangent direction of an end of the second flow guide surface is staggered with respect to the front wheel.

[0014] According to a second aspect of the present disclosure, a vehicle is provided, comprising a vehicle body, a front wheel, and the front wheel air baffle described above, wherein the front wheel air baffle body of the front wheel air baffle is mounted to the vehicle body and located in front of the front wheel.

[0015] Optionally, a distance between the rear end of the extension plate and the outer circumferential surface of the front wheel in the front-rear direction is greater than 10mm.

[0016] By the above technical solution, the extension plate extending downward is arranged at the rear end of the front wheel air baffle body, and the lower surface of the front wheel air baffle body is the first flow guide surface, and the lower surface of the extension plate is the second flow guide surface. Since the included angle α between the first flow guide surface and the horizontal direction is less than the included angle γ between the second flow guide surface and the horizontal direction, an included angle between the first flow guide surface and the second flow guide surface can be less than 180°, so that when the airflow flows to the rear end of the first flow guide surface of the front wheel air baffle body, the airflow can be turned downward at the included angle between the first flow guide surface and the second flow guide surface, that is, the airflow can be downwardly guided by the second flow guide surface at this position, so that the airflow can flow in a direction away from the wheel cavity of the front wheel, thereby facilitating the reduction of the airflow into the wheel cavity of the front wheel, achieving the purpose of further reducing the vehicle wind resistance and reducing the vehicle energy consumption.

[0029] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0030] In the present disclosure, the orientation words such as "up, down, left, right, top, bottom" are defined with the up, down, left, right, top, bottom in the normal driving state of the vehicle, only for the convenience of describing the present disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a particular orientation, and a particular orientation configuration and operation, therefore, it cannot be understood as a limitation on the present disclosure, for example, up, down, top, bottom can be the up, down, top, bottom when the vehicle is in the normal use state. "Inner, outer" refers to the inner and outer of the contour of the corresponding component, in addition, the terms "first", "second" and the like are used to distinguish one element from another element, and do not have sequentiality and importance.

[0031] In the description of the present disclosure, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "connect", "connected", "install" should be understood in a broad sense, for example, can be fixedly connected, can also be detachably connected, or integrally connected, can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0032] According to a first aspect of the present disclosure, a front wheel deflector is provided, as shown in Figures 1 to 5 、 Figures 7 to 8 The front wheel deflector body 20 is used to be installed on the vehicle body 10 and located in front of the front wheel 11, the lower surface of the front wheel deflector body 20 is a first flow guide surface 21, the first flow guide surface 21 extends downwardly in the direction close to the front wheel 11, the extension plate 30 is arranged at the rear end of the front wheel deflector body 20, the lower surface of the extension plate 30 is a second flow guide surface 31 connected with the first flow guide surface 21, the second flow guide surface 31 extends downwardly in the direction close to the front wheel 11, the included angle α of the second flow guide surface 31 relative to the horizontal direction is greater than the included angle γ of the first flow guide surface 21 relative to the horizontal direction.

[0033] Through the above technical solution, the extension plate 30 extending downwardly is arranged at the rear end of the front wheel deflector body 20, and the lower surface of the front wheel deflector body 20 is the first flow guide surface 21, and the lower surface of the extension plate 30 is the second flow guide surface 31. Since the included angle α between the first flow guide surface 21 and the horizontal direction is smaller than the included angle γ between the second flow guide surface 31 and the horizontal direction, an included angle smaller than 180° can be formed between the first flow guide surface 21 and the second flow guide surface 31. When the airflow flows to the rear end of the first flow guide surface of the front wheel deflector body 20, the airflow can be turned downwardly at the included angle between the first flow guide surface 21 and the second flow guide surface 31, that is, the airflow can be guided downwardly by the second flow guide surface 31 at this position, so that the airflow can flow in the direction away from the wheel cavity of the front wheel 11, thereby facilitating to reduce the airflow flowing into the wheel cavity of the front wheel 11, achieving the purpose of further reducing the wind resistance of the whole vehicle and reducing the energy consumption of the whole vehicle.

[0034] In addition, the present disclosure can achieve the purpose of reducing wind resistance and increasing endurance by arranging the extension plate 30 at the rear end of the front wheel deflector body 20 without changing the ground clearance of the front wheel deflector body 20 and without affecting the passability of the bottom of the vehicle 100.

[0035] Figure 5 A schematic view of the airflow flowing through the front wheel deflector 2 provided by the present disclosure during the vehicle driving process, Figure 6 A schematic view of the airflow flowing through the front wheel deflector 2' in the related art during the vehicle driving process, inFigure 5 and Figure 6 In the above, the thick solid line represents the flow path of the airflow, and the arrow represents the flow direction of the airflow. By comparison Figure 5 and Figure 6 It can be seen that when the front wheel baffle 2 provided by the present disclosure is at the same installation height as the front wheel baffle 2' in the related art, compared to the position of the airflow after flowing through the front wheel baffle 2 provided by the present disclosure, the position of the airflow after flowing through the front wheel baffle 2' in the related art is closer to the wheel cavity of the front wheel 11, and thus is more likely to be rolled into the wheel cavity, resulting in increased wind resistance. That is, without changing the ground clearance of the front wheel baffle body 20, the front wheel baffle 2 provided by the present disclosure can make the airflow flow away from the wheel cavity of the front wheel 11, thereby reducing the airflow rolled into the wheel cavity of the front wheel 11.

[0036] If the airflow is desired to flow through the front wheel baffle 2' in the related art, and its position is approximately the same as that of the airflow flowing through the front wheel baffle 2 provided by the present disclosure, the installation height of the front wheel baffle 2' in the related art needs to be lowered, which will result in poor passability of the vehicle 100. Therefore, the present disclosure can guide the airflow away from the wheel cavity of the front wheel 11 without affecting the passability of the bottom of the vehicle 100.

[0037] The above-mentioned extension plate 30 is arranged at an angle with the front wheel baffle body 20, and the angle can be set to any suitable angle, which can achieve the purpose of guiding the airflow away from the wheel cavity of the front wheel 11.

[0038] In an embodiment provided by the present disclosure, as shown in Figure 3 The first flow guide surface 21 can be an arc surface with the convex direction downward, and the second flow guide surface 31 can be an arc surface with the concave direction upward. In this way, the end of the first flow guide surface 21 can be a structure that does not extend downward or gently extends downward, which can be beneficial for smoothly guiding the airflow, thereby reducing the resistance at this position. However, the end of the second flow guide surface 31 is a structure that extends downward, which can guide the airflow to flow downward by using the second flow guide surface 31, thereby being beneficial for increasing the difficulty of the airflow flowing into the wheel cavity of the front wheel 11, and further reducing the airflow rolled into the wheel cavity of the front wheel 11.

[0039] Optionally, the curvature radius of the first flow guide surface 21 can be greater than the curvature radius of the second flow guide surface 31, that is, the bending degree of the first flow guide surface 21 is less than that of the second flow guide surface 31, so that the first flow guide surface 21 can achieve a relatively gentle flow guide, so that the airflow can pass through the first flow guide surface 21 gently, thereby reducing the wind resistance. Moreover, the second flow guide surface 31 has a greater bending degree than the first flow guide surface 21, which can effectively guide the airflow downward and ensure that the airflow is away from the front wheel 11.

[0040] In order to improve the smoothness of the airflow flowing through the junction between the front wheel wind deflector 2 and the extension plate 30, the first flow guide surface 21 and the second flow guide surface 31 can be connected by a circular arc transition. The circular arc transition can smoothly guide the flow direction of the airflow, reduce the formation of turbulent flow or vortex, thereby reducing wind resistance and energy consumption.

[0041] In some embodiments provided by the present disclosure, as shown in Figure 3 The extension plate 30 can extend along the length direction of the rear end of the front wheel wind deflector body 20, so that the extension plate 30 can be engaged with the entire rear end of the front wheel wind deflector body 20, that is, the entire rear end edge of the front wheel wind deflector body 20 is connected with the entire front end edge of the extension plate 30. In this way, the large space in the front part of the front wheel 11 can be guided by the extension plate 30, and the reliability of the extension plate 30 in guiding the airflow direction can be improved.

[0042] It can be understood that the length direction of the rear end of the front wheel wind deflector body 20 refers to the extension direction of the rear part of the front wheel wind deflector body 20 in the left-right direction of the vehicle, which is not limited by the present disclosure.

[0043] As shown in Figure 8 The angle difference between the included angle γ and the included angle α is 10°-20°. In this way, it can be ensured that the airflow will not form turbulent flow or vortex due to the too small angle between the first flow guide surface 21 and the second flow guide surface 31, and the wind resistance will not increase to cause the energy consumption to increase. It can also be ensured that the airflow will not be unable to be guided due to the too large angle between the first flow guide surface 21 and the second flow guide surface 31.

[0044] For example, the first flow guide surface 21 is set to an angle of 30° with the horizontal direction, and the second flow guide surface 31 is set to an angle of 40-50° with the horizontal direction, and the included angle between the first flow guide surface 21 and the second flow guide surface 31 is 160°-170°, such as 165°. When the included angle is set to this angle, the airflow can be guided in the direction while not causing too much resistance to the airflow, which is conducive to reducing energy loss.

[0045] It can be understood that when the first flow guide surface 21 and the second flow guide surface 31 are both arc surfaces, the included angle α is the included angle between the tangent line of the rear end of the first flow guide surface 21 and the horizontal direction, and the included angle γ is the included angle between the tangent line of the front end of the second flow guide surface 31 and the horizontal direction. In other embodiments, the first flow guide surface 21 can not be an arc surface, but can be a plane or a combination of a plane and an arc surface; the second flow guide surface 31 can not be an arc surface, but can be a plane or a combination of a plane and an arc surface.

[0046] Optionally, asFigure 8 As shown, the falling distance L of the second flow guide surface 31 in the vertical direction is 5mm-20mm, that is, the distance L between the rear end of the front wheel air baffle body 20 and the rear end of the extension plate 30 in the vertical direction can be set to 5mm-20mm. In this way, the extension plate 30 can not be too small in height dimension to weaken or lose the guiding effect on the airflow, and can also prevent the height dimension of the extension plate 30 from being too large to form a large resistance to the airflow, and even affect the passability of the bottom of the vehicle 100.

[0047] For example, the above distance L can be set to 10mm, which can guide the direction of the airflow as much as possible while forming the least resistance to the airflow. It has been verified by experiments that when the above distance L is set to 10mm, the extension plate 30 can reduce the wind resistance to about 8count, which can improve the cruising range of the vehicle 100 by about 6km.

[0048] Alternatively, as shown in Figure 3 , the tangent direction of the end of the first flow guide surface 21 intersects the front wheel 11, and the tangent direction of the end of the second flow guide surface 31 is staggered with the front wheel 11. In this way, the second flow guide surface 31 can effectively guide the airflow to flow downward compared with the first flow guide surface 21, so as to reduce the airflow into the wheel cavity of the front wheel 11. That is, since the tangent direction of the end of the second flow guide surface 31 is staggered with the front wheel 11, the flow direction of the airflow guided by the end of the second flow guide surface 31 can be directed away from the front wheel 11, and since the extension direction of the airflow does not intersect the front wheel 11, the flow of the airflow toward the front wheel 11 can be reduced, thereby reducing the risk of the wheel cavity inhaling the airflow, which is beneficial to reducing the energy consumption of the vehicle 100.

[0049] The direction from the front end of the front wheel air baffle body 20 to the rear end of the front wheel air baffle body 20 in the present disclosure refers to the longitudinal direction of the vehicle 100 (i.e. the direction of the vehicle 100 from front to back).

[0050] According to a second aspect of the present disclosure, as shown in Figure 7 , a vehicle 100 is provided, which comprises a vehicle body 10, a front wheel 11, and the above-mentioned front wheel air baffle 2, and the front wheel air baffle body 20 of the front wheel air baffle 2 is installed on the vehicle body 10 and located in front of the front wheel 11.

[0051] In some embodiments of the present disclosure, as shown in Figure 4 , the vehicle body 10 can comprise a front lower guard plate 13 and a front lower body 14, and the front wheel air baffle body 20 can comprise a plurality of mounting portions 40, which are connected with the above-mentioned front lower guard plate 13 and the front lower body 14 to install the front wheel air baffle body 20 on the vehicle body 10, and the above-mentioned connection can be provided in the form of screwing or riveting.

[0052] In the present disclosure, as shown in Figures 4 to 7 The vehicle 100 further comprises a fender 12 mounted on the vehicle body 10, the fender 12 having a front fender portion located in front of the front wheel 11, and the extension plate 30 is located between the front wheel 11 and the front fender portion. In this way, after the airflow flows along the surface of the extension plate 30, the gas that has flowed downward can not have been rolled into the wheel cavity of the front wheel 11 before it leaves the position below the wheel cavity of the front wheel 11 due to the small distance between the end of the extension plate 30 and the surface of the front wheel 11, which is beneficial to reduce the airflow rolled into the wheel cavity of the front wheel 11.

[0053] In some embodiments of the present disclosure, the front wheel wind deflector 2 can be connected with the fender 12 to reduce the gap between the front wheel wind deflector 2 and the fender 12, which can effectively prevent the airflow from entering the wheel cavity of the front wheel 11 through the gap between the front wheel wind deflector 2 and the fender 12.

[0054] Since the vehicle 100 may vibrate during driving, the extension plate 30 close to the front wheel 11 may touch the front wheel 11, thereby causing damage to the front wheel 11, or deforming the front wheel wind deflector 2 and the extension plate 30, which reduces the guidance of the airflow. The distance between the rear end of the extension plate 30 and the outer circumferential surface of the front wheel 11 in the front-rear direction can be greater than 10 mm, so that the extension plate 30 and the front wheel 11 can be prevented from touching each other during normal driving of the vehicle 100.

[0055] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0056] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0057] In addition, various different embodiments of the present disclosure can also be combined in any manner, as long as they do not deviate from the idea of the present disclosure, and they should also be considered as disclosed by the present disclosure.
