Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a front wheel dam and a vehicle. Background Technology
[0002] With energy issues becoming increasingly severe, reducing vehicle fuel consumption and improving power and economy have become key concerns for OEMs both domestically and internationally. Lowering the drag coefficient of a vehicle can significantly reduce fuel consumption at high speeds; furthermore, for electric vehicles, a lower drag coefficient translates to a longer driving range. Therefore, reducing the drag coefficient of vehicles has become a major focus and research issue for OEMs.
[0003] Some car models have a lot of exposed tires, resulting in high tire resistance. For these models, a wind deflector is usually added to the front of the wheels to transfer tire resistance to the wind deflector, thereby reducing tire resistance. However, since most wind deflectors are straight plates, the wind deflector itself also has a large resistance, so its effect on reducing the vehicle's drag coefficient is limited. Utility Model Content
[0004] In view of the defects or deficiencies in the existing technology, this utility model provides a front wheel dam and vehicle that can guide airflow, prevent airflow from directly impacting the wheels, and reduce the resistance of the dam itself, which is beneficial to reducing the vehicle's drag coefficient.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, an embodiment of the present invention provides a front wheel wind deflector, including a wind deflector, the wind deflector being disposed on the front side of the front wheel of a vehicle, a guide plate being disposed on the bottom edge of the wind deflector, the bottom end of the guide plate being inclined to the side of the front wheel of the vehicle, and a flap being disposed at the bottom end of the guide plate, the flap being vertically disposed.
[0006] Furthermore, the wind vane includes a first end and a second end opposite to each other, wherein the first end is close to the outer side of the vehicle body and the second end is close to the inner side of the vehicle body, and the wind vane is inclined from the second end to the first end toward the wheel.
[0007] Furthermore, the upper edge of the deflector is matched with the lower edge of the front air intake.
[0008] Furthermore, the guide plate includes a first guide surface, a second guide surface, and a third guide surface, with the first guide surface and the third guide surface located on both sides of the second guide surface.
[0009] Furthermore, the first guide surface extends towards the inside of the front wheel of the vehicle at the end away from the wind vane, the second guide surface extends towards the lower part of the front wheel of the vehicle at the end away from the wind vane, and the third guide surface extends towards the outside of the front wheel of the vehicle at the end away from the wind vane.
[0010] Furthermore, the wind vane and the deflector are connected by a rounded corner transition.
[0011] Furthermore, the first guide surface, the second guide surface, and the third guide surface are all curved surfaces.
[0012] Furthermore, the bottom end face of the flap is an arc surface.
[0013] Secondly, an embodiment of the present invention provides a vehicle including a front wheel wind deflector as described above, wherein the wind deflector is located in front of the front wheel of the vehicle and its top end is connected to the bottom surface of the front bumper of the vehicle.
[0014] Furthermore, the wind vane is integrally formed with the vehicle's front bumper.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by setting a deflector at the bottom of the windshield with the bottom of the deflector tilted towards the wheel, can guide the airflow on the windshield during vehicle operation, reducing the resistance of the windshield itself. At the same time, by setting a flap at the bottom of the deflector, the airflow can be prevented from directly impacting the tire, further reducing the vehicle's drag coefficient.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0018] Example 1 A typical embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, a front wheel wind deflector includes a wind deflector 1, which is located in front of the front wheel 2 of the vehicle. Its top end is adapted to the shape of the bottom surface of the front bumper 3 of the vehicle, so that its top end is connected to the bottom surface of the front bumper 3 of the vehicle. Furthermore, the wind deflector 1 and the front bumper 3 of the vehicle are integrally formed.
[0019] The wind vane 1 is set perpendicular to the bottom surface of the front bumper 3 of the vehicle. The wind vane 1 includes a first end and a second end opposite to each other, wherein the first end is close to the outer side of the vehicle body and the second end is close to the inner side of the vehicle body. The wind vane 1 is inclined from the second end to the first end towards the wheel.
[0020] By tilting the wind vane 1 to the outside of the vehicle body, the airflow can be guided to the outside of the vehicle body, thereby avoiding the airflow directly impacting the wind vane 1 and causing an increase in wind resistance.
[0021] The lower edge of the wind vane 1 is U-shaped, and a guide plate 4 is provided at the bottom edge of the wind vane 1. The guide plate 4 is inclined. Specifically, the top of the guide plate 4 is connected to the lower edge of the wind vane 1, and the bottom of the guide plate 4 is inclined toward the front wheel 2 of the vehicle.
[0022] The upper edge of the deflector 4 is U-shaped and matches the lower edge of the front deflector 1. It includes a first deflector surface, a second deflector surface, and a third deflector surface. The first deflector surface and the third deflector surface are located on both sides of the second deflector surface. The end of the first deflector surface away from the front deflector 1 extends toward the inside of the front wheel 2 of the vehicle. The end of the second deflector surface away from the front deflector 1 extends toward the lower part of the front wheel 2 of the vehicle. The end of the third deflector surface away from the front deflector 1 extends toward the outside of the front wheel 2 of the vehicle.
[0023] Because the lower edge of the wind vane 1 is U-shaped, when the airflow passes the bottom of the wind vane 1, it will flow towards the inner side of the wheel, the lower part of the wheel, and the outer side of the wheel under the action of the guide plate 4, thereby reducing the frontal impact of the airflow on the wheel and reducing wind resistance.
[0024] The wind vane 1 and the guide vane 4 are connected by rounded corners. In this embodiment, the radius of the rounded corners is 5mm. By setting the rounded corners, the airflow can be optimized to separate smoothly at the edge. At the same time, the first guide surface, the second guide surface and the third guide surface are all curved surfaces, which can optimize the degree of airflow adhesion on their surfaces and make the airflow smoothly transition to the lower edge of the guide vane 4.
[0025] A flap 5 is provided at the bottom of the deflector 4. The flap 5 is vertically arranged. The airflow guided by the deflector 4 flows downward through the flap 5 at the bottom of the deflector 4. In this embodiment, the height of the deflector 4 is 10mm, which can guide the airflow to the lower part of the wheel, thereby avoiding the airflow impacting the tire and reducing wind resistance.
[0026] The bottom end face of the flap 5 is an arc surface. In this embodiment, the radius of the arc surface is 3mm. By setting the arc surface, the airflow can be optimized to separate smoothly at the lower edge of the flap 5.
[0027] Working principle Airflow flows from the bottom of the front bumper 3 to the wind vane 1. Since the wind vane 1 is tilted to the outside of the vehicle, part of the airflow flows to the outside of the vehicle under the guidance of the wind vane 1, and another part of the airflow flows to the lower edge of the wind vane 1. Guided by the deflector 4, it flows to the inside of the wheel, the bottom of the wheel and the outside of the wheel respectively. At the bottom of the deflector 4, the airflow is further guided downward by the flap 5, thereby avoiding the airflow impacting the tire and reducing the vehicle's wind resistance.
[0028] By setting a deflector plate 4 at the bottom of the wind vane 1, and tilting the bottom of the deflector plate 4 towards the wheel, the wind on the wind vane 1 can be guided during vehicle operation, reducing the resistance of the wind vane itself. At the same time, by setting a flap at the bottom of the deflector plate 4, the airflow can be prevented from directly impacting the tires, further reducing the vehicle's drag coefficient.
[0029] Example 2 This embodiment provides a vehicle, including a front wheel dam as described in Embodiment 1, such as... Figure 3 As shown, the wind vane 1 is located in front of the front wheel 2 of the vehicle, and its top is connected to the bottom surface of the front bumper 3 of the vehicle, and is integrally formed with the front bumper 3 of the vehicle.
[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
