[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0028] Based on this, the present embodiment provides a car tail wing and a vehicle, by arranging the telescopic structure in a closed space formed by the top plate, the bottom plate and the side plate, the telescopic structure can be prevented from being polluted by the external environment, thereby ensuring the neatness of the telescopic structure itself and significantly improving the reliability of the entire active car tail wing; it should be understood that when the telescopic end of the telescopic structure is extended, the bottom plate is lifted toward the side away from the top plate, thereby increasing the curvature of the bottom plate, and when the bottom plate is convex downward, the surface area of the bottom plate relative to the top plate increases, and when the car moves at high speed, due to the relatively long flow distance, the wind speed of the bottom plate is relatively large, while the wind speed flowing through the top plate is relatively small; due to the Bernoulli principle, the gas flow rate at the top plate is small and the pressure is large; while the gas flow rate at the bottom plate is large and the pressure is small, so a pressure difference is formed on the upper and lower surfaces of the car tail wing, generating downward air pressure, which can enhance the grip of the car in high-speed movement, make the car move more smoothly, and improve the driving experience; when the vehicle speed is reduced, the telescopic end is retracted, at this time the bottom plate can be reset by its own elasticity or can be pulled back to its original position by the telescopic end. The following is a detailed description of the embodiments:
[0029] Reference Figure 1 and Figure 2 As shown, a car rear wing provided by the present embodiment includes: a top plate 1, a bottom plate 2, a telescopic structure 3 and two side plates 4; the bottom plate 2 is an elastic plate, and one of the top plate 1 or the bottom plate 2 is provided with a connecting portion for connecting to the vehicle body, the top plate 1 and the bottom plate 2 are stacked along the height direction of the vehicle body, and the top plate 1 is located above the bottom plate 2, the front and rear sides of the top plate 1 are correspondingly connected to the front and rear sides of the bottom plate 2, and the two side plates 4 are respectively arranged on both sides of the top plate 1 along the width direction of the vehicle body, that is, arranged on the left and right sides of the top plate 1, and are surrounded by the top plate 1 and the bottom plate 2 to form a closed space; the telescopic structure 3 is installed in the closed space and is used to push the bottom plate 2 to deform, the telescopic structure 3 includes a sliding plug base 31 and a telescopic end 32, the base 31 is connected to the top plate 1, and the telescopic end 32 is connected to the bottom plate 2.
[0030] Among them, by arranging the telescopic structure 3 in a closed space formed by the top plate 1, the bottom plate 2 and the side plates 4, that is, the inside of the rear wing, the telescopic structure 3 can be prevented from being polluted by the external environment, thereby ensuring the cleanliness of the telescopic structure 3 itself, and significantly improving the reliability of the entire active automobile rear wing; it should be understood that when the telescopic end 32 of the telescopic structure 3 is extended, the bottom plate 2 is pushed up toward the side away from the top plate 1, thereby increasing the curvature of the bottom plate 2. When the bottom plate 2 bulges downward, the surface area of the bottom plate 2 relative to the top plate 1 increases. When the automobile moves at high speed, Due to the relatively long flow distance, the wind speed of the bottom plate 2 is relatively large, while the wind speed flowing through the top plate 1 is relatively small; due to the Bernoulli principle, the gas flow rate at the top plate 1 is small and the pressure is large; while the gas flow rate at the bottom plate 2 is large and the pressure is small, so a pressure difference is formed on the upper and lower surfaces of the car's rear wing, generating downward air pressure, which can enhance the grip of the car in high-speed motion, make the car move more smoothly, and improve the driving experience; when the car speed decreases, the telescopic end 32 is retracted, at which time the bottom plate 2 can be reset by its own elasticity or pulled back to its original position by the telescopic end 32.

[0032] In some embodiments, the telescopic structure 3 is arranged in a direction perpendicular to the bottom plate 2; such a setting can make the telescopic structure 3 respond more quickly, and can also make the top plate 1 better support the telescopic structure 3. The telescopic structure 3 can improve stability through the squeezing force of the top plate 1 and the bottom plate 2.
[0033] Continue to refer to Figure 1 As shown, the telescopic end 32 is provided with an arc portion 321, and the arc portion 321 protrudes toward one side of the bottom plate 2; such a configuration can utilize the arc portion 321 to avoid bending deformation of the bottom plate 2 when the telescopic end 32 lifts the bottom plate 2, and can also utilize the arc portion 321 to fit the bottom plate 2 more closely, thereby improving the supporting stability of the telescopic end 32 on the bottom plate 2.
[0034] Continue to refer to Figure 1As shown, a plurality of telescopic structures 3 are arranged along the length direction of the vehicle body, and / or a plurality of telescopic structures 3 are arranged along the width direction of the vehicle body; by disposing a plurality of telescopic structures 3 arranged along the length direction of the vehicle body and / or the width direction of the vehicle body, the contact area between the telescopic structure 3 and the bottom plate 2 can be increased, thereby ensuring that the bottom plate 2 can maintain its large curvature shape even when the vehicle moves at high speed, wherein the length direction of the vehicle body can also be understood as the direction of air flow, and the width direction of the vehicle body can be understood as the direction perpendicular to the air flow.
[0035] Continue to refer to Figure 1 As shown, one dotted line area is the original position 2a of the bottom plate, that is, the position of the bottom plate 2 when the telescopic end 32 of the telescopic structure 3 is retracted, and the other dotted line area is the original position 32a of the telescopic end, that is, the position of the telescopic end 32 of the telescopic structure 3 when it is retracted.
