[0025] Refer to Figures 1-4It can be known that the flap 3 is arranged above the main wing 2 between the two end plates 1, the flap 3 comprises a rotating wing 301, a movable wing 302 and a movable slot 303, the movable slot 303 is arranged on the inner side of the rotating wing 301, the movable wing 302 is movably connected to the inner side of the movable slot 303, one side of the rotating wing 301 is provided with a size adjusting mechanism 5 connected with the movable wing 302, the size adjusting mechanism 5 comprises a side plate 501, a drive motor 502, a winding shaft 503, a connecting rope 504 and a supporting spring 505, the side plate 501 is symmetrically arranged on one side of the rotating wing 301, the winding shaft 503 is rotatably connected to the inner side of the side plate 501, the connecting rope 504 is connected between the winding shaft 503 and the movable wing 302, the drive motor 502 is installed at one end of the side plate 501 and connected with the winding shaft 503 through a shaft coupling, the movable wing 302 and the winding shaft 503 constitute a transmission structure through the connecting rope 504, the supporting spring 505 is connected between the movable wing 302 and the movable slot 303, and the movable wing 302 and the movable slot 303 constitute an elastic structure through the supporting spring 505.

[0026] Referring to Figures 1-4 It can be known that, since the movable wing 302 is slidably connected with the rotating wing 301 through the movable slot 303, and the movable wing 302 is connected with the winding shaft 503 through the connecting rope 504, when driving at high speed on a straight road, the drive motor 502 works, and at the same time, the output end of the drive motor 502 drives the winding shaft 503 to rotate and wind the connecting rope 504, so that the position of the movable wing 302 in the movable slot 303 can be adjusted through the connecting rope 504, so as to shorten the flap 3, thereby reducing the contact area of the flap 3 with the air, and further reducing the resistance. Since the movable wing 302 is elastically connected with the movable slot 303 through the supporting spring 505, when the connecting rope 504 is loosened, the movable wing 302 will automatically reset under the action of the supporting spring 505, so that the use is more convenient.

[0027] Referring to Figure 1 , Figure 2 and Figure 4 It can be known that the angle adjusting mechanism 4 is arranged between the rotating wing 301 and the end plate 1, the angle adjusting mechanism 4 comprises a horizontal plate 401, an electric push rod 402, a hinged seat 403 and a pin shaft 404, the pin shaft 404 is movably connected between the rotating wing 301 and the end plate 1, the horizontal plate 401 is arranged on one side of the two end plates 1 which are close to each other, the electric push rod 402 is movably connected between the horizontal plate 401 and the rotating wing 301, the hinged seat 403 is connected between the electric push rod 402, the horizontal plate 401 and the rotating wing 301, and the rotating wing 301 and the end plate 1 constitute a rotating structure through the pin shaft 404.

[0028] Referring to Figure 1 , Figure 2 andFigure 4 As can be seen, since the flap 3 and the end plate 1 are rotatably connected by the pin 404, and the electric push rod 402 is rotatably connected to the flap 3 and the cross plate 401 by the hinge seat 403, the electric push rod 402 is activated and extended when cornering, causing it to push the flap 3 to deflect around the pin 404 as the axis, thereby increasing the required downforce. Furthermore, this adjustment structure greatly reduces air resistance and expands the angle adjustment range, improving the ease of use of the adjustable tail wing of the electric racing car.

[0029] See Figure 2 and Figure 4 It is known that the movable groove 303 has a guide groove 6 inside, and both ends of the movable wing 302 are provided with guide blocks 7. The guide groove 6 is set with an arc-shaped structure. The movable wing 302 and the movable groove 303 form a sliding structure through the guide groove 6 and the guide blocks 7. There are two guide grooves 6 and two guide blocks 7 symmetrically arranged about the central axis of the movable groove 303, which can play a role in supporting and limiting the movable wing 302, thereby increasing the stability of the movable wing 302 during the extension and retraction process.

[0030] The working principle of this utility model is as follows: When the race car is cornering, the driver controls the electric push rod 402 to work and extend via the control button on the steering wheel, causing it to push the flap 3 to deflect counterclockwise around the pivot 404, thereby increasing the required downforce. When the race car exits the corner, the electric push rod 402 is activated and retracted, causing the flap 3 to deflect clockwise around the pivot 404 and return to its original position. When the race car is traveling at high speed on a straight road, the driver controls the drive motor 502 via the control button on the steering wheel, causing the output end of the drive motor 502 to drive the winding shaft 503 to rotate and wind up the connecting rope 504. This allows the position of the movable wing 302 within the movable groove 303 to be adjusted via the connecting rope 504, thereby shortening the flap 3 and reducing the contact area between the flap 3 and the air, thus reducing the drag during the race car's movement.
