Detailed implementation manners

[0026] This application is made based on the inventor's discovery and recognition of the following facts and problems:

[0027] With the development of electric vehicles, the bottom of the vehicle can be designed to be more and more flat. In the related art, multiple underbody panels at the bottom of the vehicle can be smoothly connected, but it is easy to cause uneven air flow at the rear of the vehicle, resulting in unbalanced wake flow and increasing the overall wind resistance of the vehicle.

[0028] Those skilled in the art in the related art generally believe that the flatter the bottom structure of the vehicle, the more it can avoid the increase in the overall wind resistance caused by the uneven structure, thereby reducing the overall wind resistance of the vehicle.

[0029] However, through a large number of studies, the inventor of this application has found that for a too flat bottom structure of the vehicle, affected by the high-speed rotating tires and the ground extrusion effect, the air flow at the bottom will show a phenomenon that the speed is low on both sides and high in the middle, and the distribution of the air flow speed and flow rate at the bottom is uneven, and this phenomenon is more obvious the closer to the rear of the vehicle. Due to the uneven air flow at the rear of the vehicle, it is easier to cause the upper and lower imbalance of the vehicle wake flow, resulting in an increase in the overall wind resistance of the vehicle.

[0033] The vehicle underbody panel 1 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0034] As Figures 1-6 shown, the vehicle underbody panel 1 is for mounting on a vehicle chassis. The vehicle underbody panel 1 includes a middle guard panel 30 and two relatively arranged side guard panels 40. The two side guard panels 40 are respectively connected to the left and right sides of the middle guard panel 30 (the up-down, left-right, and front-back directions are as shown by the arrows in the figure). The two side guard panels 40 are recessed relative to the plane where the middle guard panel 30 is located, and the two side guard panels 40 are used to guide the airflow to diffuse to the left and right sides of the vehicle chassis.

[0035] Specifically, as Figures 1-6 shown, the length direction of the vehicle underbody panel 1 is oriented along the left-right direction.

[0036] According to the vehicle underbody panel 1 of the embodiment of the present utility model, by providing a middle part 30 of the panel and two side parts 40 of the panel, and making the two side parts 40 of the panel concave upward relative to the middle part 30 of the panel, the airflow can be guided to diffuse to the left and right sides of the vehicle chassis by the two side parts 40 of the panel. In this way, compared with the vehicle underbody panel with a flat structure in the related art, the vehicle underbody panel 1 can have a structure with a lower middle and higher sides in the left-right direction. When the airflow flows through the lower part of the vehicle underbody panel 1, the side parts 40 of the panel on both sides have a stronger drainage effect compared with the flat plate shape, which can reduce the convergence of the airflow to the middle, reduce the influence of the extrusion effect on the bottom airflow, relieve the phenomenon of lower speed on both sides and higher speed in the middle, make the distribution of the bottom airflow speed and flow more uniform, so that the upper and lower wakes are more balanced, reduce the overall vehicle aerodynamic drag, and improve the vehicle's cruising range.

[0037] Therefore, the vehicle underbody panel 1 according to the embodiment of the present utility model has the advantages of being able to reduce the overall vehicle aerodynamic drag and improve the cruising range.

[0038] Next, the vehicle underbody panel 1 according to the specific embodiment of the present utility model will be described with reference to the accompanying drawings.

[0039] Specifically, as Figures 1-6 shown, the side part 40 of the panel includes a connection end 41 and a diffusion end 42 arranged opposite to the connection end 41, and a concave upward surface 43 connected between the connection end 41 and the diffusion end 42. The side part 40 of the panel is connected to one side of the middle part 30 of the panel through the connection end 41, and the side part 40 of the panel guides the airflow to diffuse towards the connection end 41 through the concave upward surface 43. Among them, as Figure 3 shown, the diffusion end 42 is arranged higher than the connection end 41 and the middle part 30 of the panel. By making the diffusion end 42 higher than the connection end 41, it is convenient for the airflow to diffuse to both sides, enhancing the drainage effect of the side part 40 of the panel, which can further reduce the convergence of the airflow to the middle, reduce the influence of the extrusion effect on the bottom airflow, relieve the phenomenon of lower speed on both sides and higher speed in the middle, make the distribution of the bottom airflow speed and flow more uniform, so that the upper and lower wakes are more balanced, reduce the overall vehicle aerodynamic drag, and improve the vehicle's cruising range. Among them, the concave upward surface can be an arc surface, a combination of a plane and an arc surface, a combination of multi-arc surfaces with different curvatures, a combination of multi-planes, etc.

[0040] Advantageously, as Figures 1-6As shown in the figure, a plurality of strip-shaped flow guiding ribs 10 are provided on the lower surface of the middle part 30 of the guard plate. The plurality of strip-shaped flow guiding ribs 10 protrude downward from the lower surface of the middle part 30 of the guard plate and are arranged at intervals in the left-right direction of the middle part 30 of the guard plate. The length direction of the plurality of strip-shaped flow guiding ribs 10 is parallel to the length direction of the vehicle. By providing the strip-shaped flow guiding ribs 10 on the lower surface of the vehicle underbody guard 1, compared with the vehicle underbody guard with a smooth and flat lower surface in the related art, the strip-shaped flow guiding ribs 10 can be used to guide the airflow at the rear of the vehicle bottom, so that the airflow is not easily disturbed with each other in the length direction of the vehicle underbody guard 1, reducing the influence of the rotating wheel belt and the ground extrusion effect on the airflow at the rear of the vehicle bottom, making the airflow velocity and flow rate at the rear of the vehicle bottom more uniform, making the upper and lower wakes more balanced, thereby reducing the overall vehicle wind resistance and improving the vehicle's cruising range.

[0041] More advantageously, as Figures 1-6 shown, a plurality of strip-shaped flow guiding grooves 20 are provided on the lower surface of the middle part 30 of the guard plate. The plurality of strip-shaped flow guiding grooves 20 are recessed in the lower surface of the middle part 30 of the guard plate and are arranged at intervals in the left-right direction of the middle part 30 of the guard plate. The length direction of the plurality of strip-shaped flow guiding grooves 20 is parallel to the length direction of the vehicle. By providing the strip-shaped flow guiding grooves 20 on the lower surface of the vehicle underbody guard 1, compared with the vehicle underbody guard with a smooth and flat lower surface in the related art, the strip-shaped flow guiding grooves 20 can be used to form a certain disturbance to the airflow flowing through the lower surface of the vehicle underbody guard 1, making it difficult to form an airflow boundary layer, reducing the thickness of the airflow boundary layer, and delaying the airflow separation, thereby further reducing the vehicle wind resistance and improving the vehicle's cruising range.

[0042] Moreover, arranging the strip-shaped flow guiding ribs 10 and the strip-shaped flow guiding grooves 20 on the middle part 30 of the guard plate can further improve the effect of the strip-shaped flow guiding ribs 10 and the strip-shaped flow guiding grooves 20 on the middle airflow, and further facilitate reducing the overall vehicle wind resistance.

[0043] In addition, by providing the strip-shaped flow guiding ribs 10 and the strip-shaped flow guiding grooves 20 on the vehicle underbody guard 1, the strength of the guard plate can also be enhanced, making the vehicle underbody guard 1 not easily deformed.

[0044] More specifically, as Figures 1-6 shown, at least one strip-shaped flow guiding groove 20 is provided between any two adjacent strip-shaped flow guiding ribs 10. Specifically, the number of strip-shaped flow guiding ribs 10 is one more than the number of strip-shaped flow guiding grooves 20. In this way, the strip-shaped flow guiding ribs 10 can guide the airflow at the rear of the vehicle bottom, divide the airflow into multiple regions, and then the strip-shaped flow guiding grooves 20 disturb the airflow in each separated region. Through the cooperation of the strip-shaped flow guiding ribs 10 and the strip-shaped flow guiding grooves 20, while reducing the disturbance of the airflow in the left-right direction to reduce the influence of the extrusion effect on the airflow at the rear of the vehicle, disturbing the airflow boundary layer, reducing the boundary layer thickness, making the airflow velocity and flow rate at the rear of the vehicle bottom more uniform, making the upper and lower wakes more balanced, thereby reducing the overall vehicle wind resistance and improving the vehicle's cruising range.

[0045] Further, both the middle part 30 of the guard plate and the two side parts 40 of the guard plate are inclined upward relative to the horizontal plane in the vehicle front-to-rear direction, and the inclination angle of the middle part 30 of the guard plate relative to the horizontal plane is smaller than the inclination angle of the side part 40 of the guard plate relative to the horizontal plane. This can further improve the drainage effect of the side part 40 of the guard plate, further reduce the convergence of the air flow to the middle, reduce the influence of the extrusion effect on the air flow, make the air flow distribution more uniform, and thus reduce the overall vehicle aerodynamic drag.

[0046] Optionally, the inclination angle of the middle part 30 of the guard plate relative to the horizontal plane is 7 - 10 degrees, and the inclination angle of the side part 40 of the guard plate relative to the horizontal plane is 10 - 13 degrees. This can avoid the angles of the middle part 30 and the side part 40 of the guard plate being too large or too small, and avoid the angle difference between the middle part 30 and the side part 40 of the guard plate being too large or too small. On the one hand, it can facilitate improving the guiding effect on the air flow, and on the other hand, it can facilitate the forming of the vehicle underbody panel 1.

[0047] Figures 1-6 Shows a vehicle underbody panel 1 according to some examples of the present utility model. As Figure 1 、 Figure 2 、 Figures 4-6 shown, the upper surface of the vehicle underbody panel 1 is provided with a front mounting platform 50 and a rear mounting platform 60. The front mounting platform 50 is located at the front edge of the vehicle underbody panel 1, and the rear mounting platform 60 is located at the rear edge of the vehicle underbody panel 1. The front mounting platform 50 is provided with a front mounting hole 51, and the rear mounting platform 60 is provided with a rear mounting hole 61. The vehicle underbody panel 1 is adapted to be connected to the front guard plate through a threaded fastener and a buckle fitted in the front mounting hole 51, and is adapted to be connected to the edge of the rear bumper through a threaded fastener and a buckle fitted in the rear mounting hole 61. This can not only facilitate the assembly of the vehicle underbody panel 1, but also setting the front mounting platform 50 and the rear mounting platform 60 on the upper surface of the vehicle underbody panel 1 can reduce the influence of the front mounting platform 50 and the rear mounting platform 60 on the air flow, and further reduce the vehicle aerodynamic drag.

[0048] Specifically, as Figure 1 、 Figure 2 、 Figures 4-6 shown, both the front mounting platform 50 and the rear mounting platform 60 are multiple. The multiple front mounting platforms 50 are arranged at intervals in the left-right direction, and the multiple rear mounting platforms 60 are arranged at intervals in the left-right direction. This can make the force on the vehicle underbody panel 1 more stable, make the vehicle underbody panel 1 not easily deformed, and ensure the effect of the vehicle underbody panel 1 on the air flow.

[0049] More specifically, as Figure 1 and Figure 2As shown, the strip-shaped flow guiding rib 10 extends to the front edge of the vehicle underbody panel 1 and is spaced apart from the rear edge of the vehicle underbody panel 1, and the strip-shaped flow guiding groove 20 is spaced apart from both the front edge and the rear edge of the vehicle underbody panel 1. This not only facilitates the formation of the strip-shaped flow guiding rib 10 and the strip-shaped flow guiding groove 20 and the processing of the strip-shaped flow guiding rib 10 and the strip-shaped flow guiding groove 20, but also can improve the guiding effect of the strip-shaped flow guiding rib 10 on the air flow.

[0050] Advantageously, as Figures 1-4 shown. The upper surface of the vehicle underbody panel 1 is provided with a reinforcing rib 70. This can improve the structural strength of the vehicle underbody panel 1, prevent the vehicle underbody panel 1 from deforming, and setting the reinforcing rib 70 on the upper surface of the vehicle underbody panel 1 can avoid the influence of the setting of the reinforcing rib 70 on the air flow and ensure the flow guiding effect of the vehicle underbody panel 1.

[0051] Specifically, the strip-shaped flow guiding rib 10 and the strip-shaped flow guiding groove 20 can be integrally formed by the vehicle underbody panel 1, for example, by stamping.

[0054] Specifically, the vehicle includes a chassis, a front bumper installed at the front end of the chassis, and a rear bumper installed at the rear end of the chassis. The vehicle underbody panel 1 is at least partially installed below the rear bumper, so as to protect the rear bumper and prevent the rear bumper from being damaged. This can facilitate the vehicle underbody panel 1 to guide the air flow.

[0055] Through experimental verification, for the vehicle according to an embodiment of the present invention, compared with the method of using a flat structure for the rear bumper underbody panel, the wind resistance is reduced by 3-5 counts.
