[0071] Figure 1 is a schematic structural diagram of an electric tail wing system according to an embodiment of the present disclosure.

[0072] like Figure 1 As shown, the electric tail wing system of the present disclosure may include: a first drive assembly 100, a second drive assembly 200, a third drive assembly 300 and other components.

[0073] In the present disclosure, the first drive assembly 100 and the second drive assembly 200 can be fixed to (arranged on) the same base component 400, and accordingly, the third drive assembly 300 can drive the base component 400 to move, thereby, the third drive assembly 300 can simultaneously drive the first drive assembly 100 and the second drive assembly 200 to move.

[0074] Preferably, the base component 400 may be a plate-shaped component and has a length direction, wherein the length direction of the base component 400 is a horizontal direction, and preferably a width direction of the motor vehicle.

[0075] The third driving assembly 300 is used to drive the base component 400 to move in a second direction. Specifically, the second direction may be a vertical direction. Thus, the base component 400 can be driven by the third driving assembly 300 to generate a lifting motion.

[0076] Accordingly, as the base component 400 is raised or lowered, at least a portion of the tail wing 900 can generate a lifting action. Figure 1 As shown, the tail 900 can be divided into three parts, that is, the tail 900 includes a middle part 901 and end parts 902 located at both ends of the middle part 901. In another embodiment, although not shown in the legend of the present disclosure, those skilled in the art should know that the tail 900 can be divided into two parts from the approximately middle position in the length direction (in this case, the two parts can be referred to as two end parts 902).

[0077] Figure 2 It is a schematic structural diagram of a first accommodating component and a second accommodating component according to an embodiment of the present disclosure.

[0078] In actual use, a accommodating space is formed on the body of the motor vehicle, and a first accommodating component 700 may be disposed in the accommodating space. In the present disclosure, the first accommodating component 700 has an upward opening and may be fixed to the body.

[0079] More preferably, a second accommodating part 800 may be disposed inside the first accommodating part 700 , wherein the second accommodating part 800 may form a fixed relationship with the first accommodating part 700 .

[0080] In the present disclosure, at least part of the second accommodating component 800 extends out of the first accommodating component 700. Specifically, the upper end of the second accommodating component 800 is higher than the upper end of the first accommodating component 700. At this time, the upper end of the second accommodating component 800 is also formed into an open structure, and the middle part 901 of the rear wing 900 can be fixed on the second accommodating component 800 and at least partially close the open structure of the second accommodating component 800. Therefore, when the electric rear wing system of the present disclosure is in use, the second accommodating component 800 can be fixedly connected with the base component 400, so that the second accommodating component 800 can generate a lifting action, and the middle part 901 of the rear wing 900 fixed to the second accommodating component 800 can also be driven to lift, and at this time, air flows through the upper surface of the middle part 901 of the rear wing 900, thereby generating additional downforce.

[0081] The end portion 902 of the rear wing 900 can be driven to generate a lifting action. Specifically, in the initial state, the end portion 902 of the rear wing 900 can form a smooth continuous curved surface with the cover of the motor vehicle; when the third drive assembly 300 is activated and drives the end portion 902 to rise, the end portion 902 can rise to a preset position away from the cover of the motor vehicle, so that when the motor vehicle is in a forward or backward form, the air can act on the upper and lower surfaces of the end portion 902 of the rear wing 900, so that the rear wing 900 can provide increased grip to the motor vehicle.

[0082] Refer to Figure 1 The third driving assembly 300 of the present disclosure may include a connecting plate 301, a fourth driving device 302 and a guide assembly 303. The connecting plate 301 may be fixed to the body of the motor vehicle through a plurality of connecting members, and the position of the electric rear wing system of the present disclosure may be fixed.

[0083] The guide assembly 303 can be fixed to the connecting plate 301 and is used to guide the lifting and lowering of the base component 400. Specifically, the guide assembly 303 is configured as at least two cylindrical tubes, and adjacent cylindrical tubes can slide relative to each other, so that when the base component 400 rises, one of the two adjacent cylindrical tubes extends from the other; in the opposite working process, when the base component 400 descends, one of the two adjacent cylindrical tubes can be retracted into the other cylindrical tube.

[0084] The fourth driving device 302 can be fixed to the connecting plate 301. Specifically, the fourth driving device 302 can adopt the spoiler actuator disclosed in the Chinese invention patent publication document CN116767360A, that is, the fourth driving device 302 can drive the flocking cable in the conduit to reciprocate. Specifically, one end of the conduit can pass through the guide assembly 303 and be located inside the guide assembly. One end of the flocking cable is fixed to the base component 400, so that when the fourth driving device 302 drives the flocking cable to extend, the base component 400 can generate an upward movement; corresponding working process, when the fourth driving device 302 drives the flocking cable to retract, the base component 400 can generate a downward movement. In the present disclosure, the fourth driving device 302 can self-lock at any position, so that the base component 400 of the present disclosure is limited to a preset position.

[0088] In a preferred embodiment, the guide member 401 includes a bottom wall, wherein the bottom wall includes a length direction and a width direction, and the length direction of the bottom wall is the movement direction of the second drive assembly 200, that is, the length direction of the bottom wall is the following first direction, or the width direction of the motor vehicle, and accordingly, the first direction is perpendicular to or approximately perpendicular to the second direction.

[0089] A recessed portion is formed at the center portion of the bottom wall in the width direction, and the anchor head of the anchor can be located in the recessed portion, so that the anchor will not affect the movement of the second driving assembly 200 .

[0090] Side walls are provided at both ends of the bottom wall in the width direction, wherein the lower end of the side wall is fixedly connected to the end of the bottom wall, and the upper end of the side wall is formed with an inward flange portion, thereby preventing the sliding portion 201 from detaching from the guide member 401.

[0091] Therefore, through the setting of the guide member 401, the second driving assembly 200 can be guided by the guide member 401 so that the second driving assembly 200 moves along the first direction.

Specifically, the two ends of the rotating rod 102 are respectively connected to a first connecting rod 103, and the second driving assembly 200 is respectively connected to a second connecting rod 104, so that the second connecting rod 104 of the first driving assembly 100 of the present disclosure can generate a movement along the first direction, so that the second connecting rod 104 can drive the sliding part 201 to move along the first direction, and accordingly, the second driving assembly 200 can move along the first direction.

[0099] More preferably, when the second drive component 200 moves to the maximum stroke, that is, the distance between the second drive component 200 and the first drive component 100 is the largest, the rotating rod, the first connecting rod and the second connecting rod can be on the same straight line, thereby achieving self-locking of the position of the second drive component 200.

[0124] S106, controlling the second drive assembly to move, and causing the drive shaft to rotate along the first rotation axis by a first preset angle, and along the second rotation axis by a second preset angle. In a preferred embodiment, the first preset angle may be 40-80°, preferably about 60°, and the second preset angle may be about ±15°.

[0125] In the present disclosure, when the second drive component is controlled to operate and the drive shaft is rotated along the first rotation axis by a first preset angle, the second drive device and the third drive device rotate synchronously in the same direction and at the same speed, so that when the bracket part 230 rotates along the first rotation axis, the drive shaft will not rotate along the second rotation axis.

[0126] In addition, when the second driving assembly is controlled to move and the driving shaft is rotated along the second rotation axis by a preset angle, the second driving device stops rotating and the third driving device rotates, thereby realizing the rotation of the tail wing.

[0127] Furthermore, due to the flipping and rotating action of the end portion 902 of the rear wing, a lateral force can be provided to the vehicle, making the motor vehicle easier to control at high speeds.

[0128] In the present disclosure, the rear wing can be reset and the rear wing can be taken out of the working state by the reverse working process.
