[0002] In the related art, some vehicles add air dams to reduce the airflow entering the bottom of the vehicle, thereby increasing the air downforce and improving the vehicle's stability when driving at high speeds.

Other vehicles add front shovels to guide the airflow and improve the air downforce, thereby improving the vehicle's stability when driving at low speeds. However, due to the fixed setting of the front shovel, vehicles with added front shovels will provide insufficient tire grip when driving at high speeds, which may easily weaken the vehicle's stability when driving at high speeds.

[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0031] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0032] According to the first aspect of the embodiment of the present invention, the front lip device includes a front lip body 11 and a deflector 12, and the deflector 12 is arranged at the lower part of the front lip body 11; the driving mechanism is connected to the deflector 12 and is used to drive the deflector 12 to move relative to the front lip body 11 to adjust the gas flow rate flowing through the bottom of the vehicle 10.

[0033] The front lip device according to an embodiment of the present application comprises a front lip body 11, a deflector 12, and a drive mechanism. The front lip body 11 is typically integrated beneath the front bumper of a vehicle 10, serving as a core aerodynamic component for the vehicle 10. The deflector 12 is connected to the bottom portion thereof. The deflector 12 is dynamically adjusted by the drive mechanism to vary the flow of air passing under the vehicle 10. This ensures the vehicle's overall passability while also reducing wind resistance, enhancing the vehicle's handling stability, and improving the vehicle's aerodynamic performance under various driving conditions.

[0034] In the related art, some vehicles 10 have an air dam added to the lower part of the front lip body 11, such as Figure 1 As shown, the deflector 12 is perpendicular to the ground, reducing the airflow entering the bottom of the vehicle and increasing the air downforce, thereby improving the stability of the vehicle 10 when traveling at high speeds. However, the fixed setting of the air dam will increase the wind resistance of the vehicle 10 when traveling at low speeds. Some vehicles 10 are equipped with a front shovel at the lower part of the front lip body 11, such as Figure 2As shown, the deflector 12 is parallel to the ground, improving the stability of the vehicle 10 at low speeds. However, due to the fixed front shovel, the tire grip it provides is insufficient when the vehicle 10 is traveling at high speeds, which can easily weaken the stability of the vehicle 10 at high speeds. In the front lip device of the present embodiment, the deflector 12 is dynamically adjusted by a drive mechanism. The deflector 12 can be dynamically adjusted in its forward and backward extension and tilt angle according to the different driving conditions of the vehicle 10 to adjust the air flow rate flowing through the bottom of the vehicle 10 and improve the aerodynamic performance of the vehicle 10 under different driving conditions.

[0035] According to some embodiments of the present invention, the driving mechanism includes a driving component and a moving component. The driving component is connected to the moving component, and the moving component is connected to the guide plate 12. The driving component drives the moving component to move so that the guide plate 12 moves relative to the front lip body 11.

[0036] Specifically, the driving mechanism is composed of a driving component and a motion component. The driving component serves as a power source, and the motion component serves as a transmission medium to transmit power to the guide plate 12, thereby linking the guide plate 12 to move relative to the front lip body 11.

[0037] In some optional embodiments, the drive component may use a stepper motor, a servo motor or a linear electromagnetic drive, and receive instructions from the vehicle 10 ECU via the CAN bus. The motion component may include a gear set, a connecting rod or a flexible transmission belt. For example, the motor drives the screw to rotate through a worm gear reduction mechanism, which is converted into a linear displacement of the guide plate 12. The connection point between the motion component and the guide plate 12 adopts a ball joint structure, which allows multi-degree-of-freedom fine-tuning to avoid mechanism jamming caused by chassis vibration of the vehicle 10. In addition, the layered design of the drive mechanism realizes the decoupling of power transmission and actuator, which is convenient for fault diagnosis and component replacement.

[0038] According to some embodiments of the present invention, the motion assembly includes a sliding assembly and a rotating assembly to enable the deflector 12 to move relative to the front lip body 11 .

[0039] like Figure 3-4 The guide plate 12 can move relative to the front lip body 11 through the sliding component and the rotating component to achieve a close fit between the guide plate 12 and the lower surface of the front lip body 11. Figure 4 The position shown is hidden under the lower surface of the front lip body 11 when the vehicle 10 is accelerating or traveling at a constant speed, which can effectively reduce the impact of the deflector 12 on the wind resistance of the vehicle 10.

[0040] According to some embodiments of the present invention, the driving member includes a first sub-driving member, a sliding component connected to the guide plate 12, the first sub-driving member is connected to the sliding component, and is used to drive the guide plate 12 to move along the front and rear direction of the vehicle 10; a second sub-driving member, a rotating component connected to the guide plate 12, and the second sub-driving member is connected to the rotating component, and is used to drive the guide plate 12 to move along the up and down direction of the vehicle 10.

[0041] Specifically, the deflector 12 can be moved along the front and rear directions of the vehicle 10 through the sliding component, and the deflector 12 can be moved along the up and down directions of the vehicle 10 through the rotating component. That is, when the sliding component and the rotating component act on the deflector 12 at the same time, the deflector 12 can be moved along the front and rear directions of the vehicle 10 and along the up and down directions of the vehicle 10 at the same time, ensuring that the deflector 12 is tightly fitted with the lower surface of the front lip body 11, and is used to be hidden on the lower surface of the front lip body 11 when the vehicle 10 is accelerating or traveling at a constant speed, which can effectively reduce the impact of the introduction of the deflector 12 on the wind resistance of the vehicle 10.

[0042] According to some embodiments of the present invention, the sliding assembly includes a first slide rail 13 and a first slider 14 adapted to the first slide rail 13, the first slider 14 is connected to the deflector 12, the first slide rail 13 extends along the front and rear direction of the vehicle 10, and the first sub-drive member is connected to the first slider 14, for driving the first slider 14 to slide along the deflector 12 so that the deflector 12 moves along the front and rear direction of the vehicle 10.

[0043] like Figure 3-8 As shown, the first sub-driving member pushes the slider to move, and the first slide rail 13 is installed along the front-rear direction of the vehicle 10 , so that the first sub-driving member drives the first slider 14 to move along the first slide rail 13 in the front-rear direction of the vehicle 10 .

[0044] In some optional embodiments, the first sub-drive member is a linear motor, which drives the slider to move linearly through a ball screw. In addition, mechanical limit blocks and Hall sensors are set at both ends of the first slide rail 13 to prevent the first slider 14 from being damaged by overtravel.

[0045] According to some embodiments of the present invention, the deflector 12 is further provided with a rotating shaft 15 , and the driving member further includes a third sub-driving member, which is connected to the rotating shaft 15 and is used to drive the deflector 12 to rotate relative to the front lip body 11 .

[0046] like Figure 3-8As shown, the deflector 12 is additionally provided with a rotating shaft 15, and the deflector 12 is rotated around the rotating shaft 15 by a third sub-driving member, thereby expanding the movement dimension of the deflector 12, and realizing adaptive adjustment of the rotation angle of the deflector 12 at the lower part of the front lip body 11, for example, the deflector 12 can be parallel to the ground, the deflector 12 can have a certain angle with the ground, or the deflector 12 can be perpendicular to the ground. In addition to the aerodynamic benefits of the integrated front shovel and the air dam, the deflector 12 can also be adjusted to have a certain angle with the ground in combination with the actual specific driving state of the vehicle 10, thereby realizing effective regulation of wind resistance and downforce, enhancing the handling stability of the vehicle 10, and improving the aerodynamic performance of the vehicle 10 under different driving conditions.

[0047] In some optional embodiments, the third sub-driving member is a driving motor or an engine.

[0048] According to some embodiments of the present invention, the rotation shaft 15 extends in the left-right direction of the vehicle 10. Specifically, the rotation shaft 15 is arranged horizontally in the left-right direction of the vehicle 10. This arrangement ensures that the deflector 12 is subjected to symmetrical forces on both sides when rotating about the rotation shaft 15, thereby avoiding deflection vibration caused by uneven torque.

[0049] According to some embodiments of the present invention, the rotating assembly is connected between the first slider 14 and the rotating shaft 15 to enable the deflector 12 to move in the up-down direction of the vehicle 10 .

[0050] like Figure 3-8 As shown, the rotating assembly connects the first slider 14 and the rotating shaft 15 through a mechanical structure. The first slider 14 moves along the front and rear directions of the vehicle 10. That is, by adjusting the rotating shaft 15 along the up and down directions of the vehicle 10 through the rotating assembly, the deflector 12 can be synchronously moved along the up and down directions of the vehicle 10, and the overall structure of the front lip device can be simplified.

[0051] According to some embodiments of the present invention, the rotating assembly includes a roller 16 and a flexible member 17 . The roller 16 is disposed on the first slider 14 . The roller 16 is connected to the rotating shaft 15 through the flexible member 17 . The second sub-driving member is connected to the roller 16 .

[0052] like Figure 3-8 As shown, the rotating assembly includes a roller 16 and a flexible member 17. The second sub-driving member drives the roller 16 to rotate, thereby driving the flexible member 17 to contract or extend. The flexible member 17 is connected to the rotating shaft 15, that is, the flexible member 17 contracts or extends to achieve synchronous movement of the deflector 12 along the up and down directions of the vehicle 10.

[0053] In some optional embodiments, the second sub-driving member is a driving motor or an engine to drive the roller 16 to rotate.

[0054] According to some embodiments of the present invention, there is one or more rollers 16. There are two rollers 16, and the second sub-driving member drives the two rollers 16 to rotate in opposite directions.

[0055] Specifically, when there is only one roller 16, a support rod is required to support the roller. When the roller rotates clockwise or counterclockwise, the flexible member 17 contracts or extends, achieving synchronous movement of the deflector 12 along the vertical direction of the vehicle 10. When there are multiple rollers 16, at least two rollers 16 typically rotate in opposite directions to achieve reciprocating motion of the flexible member 17, causing the flexible member 17 to contract or extend, achieving synchronous movement of the deflector 12 along the vertical direction of the vehicle 10. Furthermore, a single roller 16 solution is generally suitable for low-load scenarios, with a simple structure and low cost. Dual rollers 16 driven in opposite directions can offset lateral forces and improve system stability.

[0056] In some optional embodiments, when there are two rollers 16 , the two rollers 16 are spaced apart in the front-to-rear direction of the vehicle 10 .

[0057] According to some embodiments of the present invention, the flexible member 17 is a flexible steel bar, which replaces traditional chains or wire ropes and has advantages such as no lubrication requirement and corrosion resistance. In some optional embodiments, the roller 16 has a V-groove on its surface to engage with the flexible steel bar.

[0058] In some optional embodiments, the first sub-driving member drives the sliding assembly to drive the deflector 12 to move in the front and rear directions of the vehicle 10, and at the same time, the second sub-driving member drives the rotating assembly to drive the deflector 12 to move in the up and down directions of the vehicle 10. Under the combined action, the deflector 12 moves along the lower surface of the front lip body 11 to the position shown in FIG. Figure 5 Then, the third sub-drive member drives the shaft 15 to rotate, so that the guide plate 12 is parallel to the ground. Figure 6 In the position shown, the deflector 12 can act as a front shovel by dividing the airflow hitting the front of the vehicle, thereby forming a high-pressure area above the deflector 12 and a low-pressure area below the deflector 12, thereby increasing the downforce in front of the vehicle 10. This can increase the grip of the tires when the vehicle 10 is turning at low speeds, while almost not increasing the wind resistance of the vehicle 10. Further, by driving the rotating shaft 15 to rotate by the third sub-drive member, the deflector 12 can be made perpendicular to the ground. Figure 7 In the position shown, the deflector 12 can act as an air dam, introducing a large low-pressure area by introducing a backflow vortex at the rear of the deflector 12, thereby greatly increasing the downforce on the front of the vehicle 10, thereby increasing the tire grip of the vehicle 10 when negotiating a high-speed curve; in addition, the deflector 12 can also act as a speed brake when the vehicle 10 decelerates and brakes on a straight road, shortening the deceleration time of the vehicle 10. In addition, by driving the rotating shaft 15 to rotate by the third sub-drive member, the deflector 12 can be made to have a certain angle with the ground, such as Figure 8 The position shown can effectively balance the wind resistance and front downforce of the vehicle 10, which can ensure that the tire grip of the vehicle 10 does not increase the wind resistance too much when passing through a medium-speed corner.

[0059] According to some embodiments of the present invention, the sliding assembly and the rotating assembly are provided on the front lip body 11. Figure 4-8 As shown, the sliding guide rail and the rotating mechanism are directly fixed to the inner frame of the front lip body 11. The integrated installation can reduce the overall volume of the front lip device, which is beneficial to saving space in the vehicle.

[0060] According to some embodiments of the present invention, a seal 18 is provided on the front lip body 11 to prevent airflow from entering the vehicle interior through the front lip body 11. For example, a flexible, stretchable and compressible foam can be filled on the lower surface of the front lip body 11 to prevent airflow from entering the vehicle interior through the lower surface of the front lip body 11. Furthermore, the addition of a flexible foam can effectively suppress wind noise caused by airflow entering the vehicle interior.

[0061] According to the control method of the second aspect embodiment of the present invention, applied to the front lip device of the above embodiment, the method includes: controlling the driving mechanism to drive the deflector 12 to move relative to the front lip body 11 according to the state of the vehicle 10 to adjust the gas flow rate flowing through the bottom of the vehicle 10.

[0062] According to the control method of the embodiment of the present application, the front lip device of the above embodiment is applied, and the method specifically includes: according to the different driving states of the vehicle 10, the driving mechanism can dynamically adjust the movement of the deflector 12 relative to the front lip body 11 to change the gas flow rate flowing through the bottom of the vehicle 10, thereby ensuring the passability of the entire vehicle while reducing wind resistance, enhancing the handling stability of the vehicle 10, and improving the aerodynamic performance of the vehicle 10 under different driving conditions.

[0063] According to some embodiments of the present invention, the driving mechanism is controlled according to the state of the vehicle 10 to drive the deflector 12 to move relative to the front lip body 11, specifically including: when the vehicle 10 is in linear motion, the deflector 12 is controlled to move relative to the front lip body 11 according to the acceleration of the vehicle 10.

[0064] Specifically, the vehicle 10 is in linear motion, and the movement of the deflector 12 relative to the front lip body 11 is controlled according to the acceleration of the vehicle 10, that is, when the vehicle 10 is accelerating or traveling at a constant speed, the impact of the wind resistance of the vehicle 10 due to the introduction of the deflector 12 is reduced as much as possible; when the vehicle 10 is decelerating, the deflector 12 acts as a deceleration plate, shortening the deceleration time of the vehicle 10, enhancing the handling stability of the vehicle 10, and improving the aerodynamic performance of the vehicle 10 under different driving conditions.

[0065] In some optional embodiments, whether the vehicle 10 is moving in a straight line is determined by using driving data transmitted back by a steering sensor installed on the vehicle 10 .

[0066] In some optional embodiments, the acceleration and deceleration conditions of the vehicle 10 may be obtained in real time through the driving data transmitted back by an acceleration sensor installed on the vehicle 10 .

[0067] According to some embodiments of the present invention, the movement of the deflector 12 relative to the front lip body 11 is controlled according to the acceleration of the vehicle 10, specifically including: when the acceleration of the vehicle 10 is greater than or equal to zero, the deflector 12 is controlled to be parallel to the lower surface of the front lip body 11; when the acceleration of the vehicle 10 is less than zero, the deflector 12 is controlled to be perpendicular to the ground.

[0068] like Figure 9 As shown, the vehicle 10 is in a straight line. When the acceleration of the vehicle 10 is greater than or equal to zero, that is, when the vehicle 10 is traveling at a constant speed or accelerating, the controller can issue a command to control the driving mechanism to drive the deflector 12 to move to the position shown in FIG. Figure 4 The deflector 12 is hidden under the lower surface of the front lip body 11, which can effectively reduce the impact of the deflector 12 on the wind resistance of the vehicle 10. When the vehicle 10 is traveling in a straight line, when the acceleration of the vehicle 10 is less than zero, that is, when the vehicle 10 is decelerating and braking in a straight line, the controller can issue a command to control the driving mechanism to drive the deflector 12 to move to the position shown in the figure. Figure 7 In the position shown, the deflector 12 is perpendicular to the ground. At this time, the deflector 12 acts as a speed brake, shortening the deceleration time of the vehicle 10.

[0069] like Figure 4 、 Figure 9 As shown, in some optional embodiments, the vehicle 10 is traveling in a straight line. When the acceleration of the vehicle 10 is greater than or equal to zero, the first sub-driving member in the driving mechanism is controlled to drive the first slider 14 to move backward to the rear end allowed, and at the same time, the second sub-driving member in the driving mechanism is controlled to drive the two rollers 16 to press Figure 4 The roller 16 rotates in the direction shown, and then controls the third driving member to drive the guide plate 12 to rotate clockwise around the rotating shaft 15, and finally realizes the following Figure 4 With the deflector 12 in the position shown, the vehicle 10 is in a low-drag driving state.

[0070] like Figure 5 、 Figure 7 、 Figure 9 As shown, in some optional embodiments, the vehicle 10 is traveling in a straight line. When the acceleration of the vehicle 10 is less than zero, the first sub-driving member in the driving mechanism is controlled to drive the first slider 14 to move forward to the front end allowed, and at the same time, the second sub-driving member in the driving mechanism is controlled to drive the two rollers 16 to press Figure 5The roller 16 rotates in the direction shown, so as to achieve the following Figure 5 The deflector 12 is positioned as shown, and the third driving member is further controlled to drive the deflector 12 to rotate counterclockwise around the rotating shaft 15, and finally the following is achieved: Figure 7 The position of the deflector 12 shown is that the deflector 12 is perpendicular to the ground, and the airflow on the lower surface of the front lip body 11 directly hits the deflector 12. The deflector 12 acts as a deceleration plate to shorten the deceleration time of the vehicle 10.

[0071] According to some embodiments of the present invention, the driving mechanism is controlled according to the state of the vehicle 10 to drive the deflector 12 to move relative to the front lip body 11, specifically including: when the vehicle 10 is in a turning motion, the deflector 12 is controlled to move relative to the front lip body 11 according to the turning speed of the vehicle 10.

[0072] Specifically, the vehicle 10 is in a turning motion, and the movement of the deflector 12 relative to the front lip body 11 is controlled according to the turning speed of the vehicle 10. That is, according to the turning speed of the vehicle 10, the driving mechanism is controlled to make the deflector 12 parallel to the ground, the deflector 12 have a certain angle with the ground, or the deflector 12 is perpendicular to the ground. While ensuring the passability of the entire vehicle, it can also reduce wind resistance, enhance the handling stability of the vehicle 10, and improve the aerodynamic performance of the vehicle 10 under different driving conditions.

[0073] In some optional embodiments, whether the vehicle 10 is turning is determined by using driving data transmitted back by a steering sensor installed on the vehicle 10 .

[0074] In some optional embodiments, the turning speed of the vehicle 10 may be obtained in real time through driving data transmitted back by an onboard speed sensor installed on the vehicle 10 .

[0075] According to some embodiments of the present invention, the movement of the deflector 12 relative to the front lip body 11 is controlled according to the turning speed of the vehicle 10, specifically including: when the turning speed of the vehicle 10 is less than a first threshold, the deflector 12 is controlled to be parallel to the ground; when the turning speed of the vehicle 10 is greater than or equal to the first threshold and less than a second threshold, the deflector 12 is controlled to have a certain angle with the ground; when the turning speed of the vehicle 10 is greater than or equal to the second threshold, the deflector 12 is controlled to be perpendicular to the ground.

[0076] like Figure 9 As shown, the vehicle 10 is in a turning state. When the turning speed of the vehicle 10 is less than a first threshold, the control driving mechanism drives the deflector 12 to move to the position shown in FIG. Figure 6In the position shown, the deflector 12 is parallel to the ground, and by dividing the airflow hitting the front of the vehicle, a high-pressure area is formed above the deflector 12, and a low-pressure area is formed below the deflector 12, thereby increasing the downforce on the front of the vehicle 10. This can increase the grip of the tires when the vehicle 10 is turning at low speeds, while almost not increasing the wind resistance of the vehicle 10. When the turning speed of the vehicle 10 is greater than or equal to the first threshold and less than the second threshold, the control drive mechanism drives the deflector 12 to move to the position shown. Figure 8 The position shown, that is, the deflector 12 has a certain angle with the ground, which can effectively balance the wind resistance and front downforce of the vehicle 10, ensuring the tire grip of the vehicle 10 when passing a medium-speed corner while not increasing the wind resistance too much. At this time, the vehicle 10 is in a medium downforce driving state. When the turning speed of the vehicle 10 is greater than or equal to the second threshold, the control driving mechanism drives the deflector 12 to move to the position shown in FIG. Figure 7 In the position shown, that is, the deflector 12 is perpendicular to the ground, a larger low-pressure area is introduced by introducing a backflow vortex at the rear of the deflector 12, which can greatly increase the downforce on the front of the vehicle 10, ensuring the tire grip requirement of the vehicle 10 when negotiating high-speed corners. At this time, the vehicle 10 is in a high-downforce driving state.

[0077] According to some embodiments of the present invention, the method further includes: controlling the length of the deflector 12 extending relative to the front lip body 11, and / or controlling the angle between the deflector 12 and the ground, based on the turning speed of the vehicle 10, the first threshold value, and the second threshold value, so as to achieve precise control of the gas flow rate flowing through the bottom of the vehicle 10, effectively balance the tire grip requirements and the low wind resistance requirements, and further improve the aerodynamic performance of the vehicle 10 under different driving conditions.

[0078] In some optional embodiments, when the vehicle 10 is turning and the speed of the vehicle 10 is less than a first threshold, the first sub-driving member in the driving mechanism is controlled to drive the first slider 14 to move forward, and the second sub-driving member in the driving mechanism is controlled to drive the two rollers 16 to press Figure 5 The roller 16 rotates in the direction shown, so as to achieve the following Figure 5 The deflector 12 is positioned as shown, and the third driving member is further controlled to drive the deflector 12 to rotate counterclockwise around the rotating shaft 15, and finally the following is achieved: Figure 6 The deflector 12 is in the position shown, that is, the deflector 12 is parallel to the ground. At this time, the deflector 12 acts as a front shovel, and the vehicle 10 is in a low downforce driving state. In addition, when the vehicle 10 travels at a speed less than a first threshold, the deflector 12 moves to the position shown. Figure 5 The extension length of the deflector 12 corresponding to the position shown can be adaptively adjusted according to the driving speed of the vehicle 10. The specific control algorithm is as follows: Figure 9In the low-pressure mode shown, the speed V of the vehicle 10 is obtained via a speed sensor. The extended length L of the deflector 12 is calculated as (V / Q1)^2*L_max, where Q1 is the first threshold, i.e., the vehicle 10's maximum speed for negotiating a slow-speed corner, and L_max is the maximum extended length of the deflector 12. At this point, the angle A between the deflector 12 and the incoming airflow is 0°. This allows the deflector 12 to divide the airflow striking the front of the vehicle, creating high-pressure and low-pressure areas above and below the deflector 12, respectively. This increases downforce on the front of the vehicle 10, improving tire grip when negotiating a slow-speed corner, while barely increasing wind resistance.

[0079] In some optional embodiments, the vehicle 10 is turning. When the speed of the vehicle 10 is greater than or equal to a first threshold and less than a second threshold, the first sub-driving member in the driving mechanism is controlled to drive the first slider 14 to move forward, and the second sub-driving member in the driving mechanism is controlled to drive the two rollers 16 to press Figure 5 The roller 16 rotates in the direction shown, so as to achieve the following Figure 5 The deflector 12 is positioned as shown, and the third driving member is further controlled to drive the deflector 12 to rotate counterclockwise around the rotating shaft 15, and finally the following is achieved: Figure 8 The deflector 12 is in the position shown, that is, the deflector 12 has a certain angle with the ground, and the vehicle 10 is in a medium downforce driving state. In addition, when the vehicle 10 is traveling at a speed greater than or equal to the first threshold and less than the second threshold, the deflector 12 moves to the position shown. Figure 5 The extension length of the deflector 12 corresponding to the position shown can be adaptively adjusted according to the driving speed of the vehicle 10. The specific control algorithm is as follows: Figure 9 In the medium downforce mode, the speed sensor measures the vehicle 10's speed V, and the deflector 12's extended length L = L_max, where L_max is the maximum extended length of the deflector 12. At this point, the angle A between the deflector 12 and the incoming airflow is arccos(1-((V-Q1) / (Q2-Q1))^2), where Q1 is the first threshold, representing the vehicle 10's speed limit for negotiating slow corners, and Q2 is the second threshold, representing the vehicle 10's speed limit for negotiating medium-speed corners. This effectively balances the vehicle 10's wind resistance and front downforce, ensuring tire grip while minimizing wind resistance when negotiating medium-speed corners.

[0080] In some optional embodiments, the vehicle 10 is turning. When the turning speed of the vehicle 10 is greater than or equal to the second threshold, the first sub-driving member in the driving mechanism is controlled to drive the first slider 14 to move forward, and the second sub-driving member in the driving mechanism is controlled to drive the two rollers 16 to press Figure 5 The roller 16 rotates in the direction shown, so as to achieve the following Figure 5The deflector 12 is positioned as shown, and the third driving member is further controlled to drive the deflector 12 to rotate counterclockwise around the rotating shaft 15, and finally the following is achieved: Figure 7 The deflector 12 is in the position shown, that is, the deflector 12 is perpendicular to the ground. At this time, the deflector 12 acts as an air dam, and the vehicle 10 is in a high downforce driving state. In addition, when the turning speed of the vehicle 10 is greater than or equal to the second threshold, the deflector 12 moves to the position shown. Figure 5 The extension length of the deflector 12 corresponding to the position shown can be adaptively adjusted according to the driving speed of the vehicle 10. The specific control algorithm is as follows: Figure 9 In high-pressure mode, the speed sensor measures vehicle 10's speed V. The deflector 12's extended length, L, is L_max, where L_max represents the maximum extended length. At this point, the angle A between the deflector 12 and the incoming flow is 90°. By introducing a large low-pressure area behind the deflector 12 and a backflow vortex, this significantly increases downforce on the front of the vehicle 10, ensuring tire grip when negotiating high-speed corners.

[0081] In some optional embodiments, the driving status of the vehicle 10 is monitored in real time through sensor data of the vehicle 10, and the driving mechanism is controlled according to the real-time status of the vehicle 10 to drive the deflector 12 to move relative to the front lip body 11, so as to adjust the gas flow rate flowing through the bottom of the vehicle 10, thereby ensuring the passability of the entire vehicle, reducing wind resistance, enhancing the handling stability of the vehicle 10, and improving the aerodynamic performance of the vehicle 10 under different driving conditions.
