The transmission structures of the two spoilers 1 can be the same, which will not be described here.

[0039] Preferably, Figure 1 and Figure 4As shown, in an embodiment, the side skirt 2 can be arranged on both sides in the width direction of the vehicle. The side skirt 2 may include a recovery bin 21, an arcuate rack 22, a wing 23, a third gear 24, a fourth gear 25 and a second motor 26. Among them, the recovery bin 21 can be installed at the bottom of both sides of the vehicle. The recovery bin 21 can be a rectangular box body, and the end of the recovery bin 21 away from the vehicle can be formed with an opening (i.e., formed as an open side). The arcuate rack 22 can be installed inside the recovery bin 21. The arcuate rack 22 can be fixed in the recovery bin 21 by clamping or welding. The first end of the wing 23 can be connected to the recovery bin 21 through a rotating shaft 4, so that the wing 23 can rotate relative to the recovery bin 21 to achieve extension or retraction in the recovery bin 21. The second end of the wing 23 can be formed into an arc, and the wing 23 can move along the extension direction of the arcuate rack 22. Specifically, a third gear 24 may be provided inside the recovery bin 21, and the third gear 24 may mesh with the arc-shaped rack 22. Preferably, an arc-shaped groove for limiting may be provided inside the recovery bin 21 at the position corresponding to the motion trajectory of the third gear 24, so that the third gear 24 can move along the arc-shaped rack 22. A fourth gear 25 may be provided inside the wing plate 23, and the fourth gear 25 meshes with the third gear 24. The wing plate 23 may be provided with a window at a position corresponding to the third gear 24, and the fourth gear 25 may be exposed from the window to achieve meshing with the third gear 24. More preferably, the third gear 24 may be divided into two layers, the lower layer of the third gear 24 may mesh with the arc-shaped rack 22, and the upper layer of the third gear 24 may mesh with the fourth gear 25, so as to achieve transmission connection between the fourth gear 25 and the arc-shaped rack 22. In addition, the second motor 26 may be installed inside the wing plate 23 by screws. A crown gear 27 may be installed at the output end of the second motor 26. The crown gear 27 can mesh with the fourth gear 25, so that the second motor 26 can be indirectly connected to the third gear 24, thereby driving the wing plate 23 to extend or retract into the recovery bin 21. In addition, the transmission structures of the two side skirts 2 can be the same, which will not be repeated here.

[0040] Further, preferably, Figure 1 and Figure 4In the embodiment, the two ends of the recovery bin 21 in the length direction are provided with a rotating shaft 4, and the rotating shaft 4 can be arranged on the side of the recovery bin 21 away from the vehicle. The recovery bin 21 can be rotatably mounted on the main body of the vehicle through the rotating shaft 4. The side skirt 2 can also include a shaft 211, a first rack 214 and a third motor 215. Among them, the shaft 211 can be installed at the end of the recovery bin 21 close to the vehicle. A shaft gear 212 and a fifth gear 213 (which can be keyed) that rotate synchronously with the shaft 211 can be arranged on the shaft 211. A first rack 214 can be installed on the structural member of the vehicle chassis. The first rack 214 can be arranged on the vehicle in the vertical direction. The shaft gear 212 can mesh with the first rack 214, so that the end of the recovery bin 21 away from the vehicle can move in the vertical direction, and then the recovery bin 21 as a whole can be deflected around the rotating shaft 4 to control the extension direction of the wing 23. Preferably, the number of the shaft gears 212 can be two, and the two shaft gears 212 are respectively arranged at the two ends of the length direction of the recovery bin 21. The two first racks 214 are arranged corresponding to the two shaft gears 212. The third motor 215 can be installed inside the wing plate 23 by screws. The output end of the third motor 215 can be installed with a sixth gear 216, and the sixth gear 216 can be engaged with the fifth gear 213, so that the third motor 215 can be connected to the fifth gear 213 through the sixth gear 216, thereby driving the recovery bin 21 to swing up and down. When the vehicle is traveling on an uneven road, the extension angle of the wing plate 23 is adjusted by the third motor 215, so as to balance the vehicle to ensure the smooth driving of the vehicle.

[0041] Preferably, Figure 1 and Figure 2As shown, in an embodiment, the diffuser 3 can be arranged at the center of the bottom of the rear end of the vehicle. The diffuser 3 may include a plurality of blades 31, a first cross bar 32, a second cross bar 33, a second rack 34 and a fourth motor 35. Among them, the blade 31 may be a rectangular plate, and the sizes of the plurality of blades 31 may be equal. The plurality of blades 31 may be arranged at intervals along the width direction of the vehicle, and the plurality of blades 31 may be aligned with each other. The first cross bar 32 may be hinged to the ends of the plurality of blades 31 respectively, and the first cross bar 32 may be movably mounted on the bottom of the vehicle (the two ends of the first cross bar 32 may be mounted in the slide groove). The second cross bar 33 may be hinged to the middle of the plurality of blades 31 respectively, and the second cross bar 33 may move along the width direction of the vehicle with the blades 31. The second rack 34 may be fixed to the second cross bar 33 (may be integrally formed). The fourth motor 35 may be mounted on the vehicle by bolts. The output shaft of the fourth motor 35 can be connected to the seventh gear 36, and the seventh gear 36 can mesh with the second rack 34, so that the fourth motor 35 can drive the second rack 34 to drive the second cross bar 33 to move in the width direction, thereby realizing the swing of the blade 31.

[0042] Preferably, Figure 1 and Figure 2 As shown, in an embodiment, the control component may include a central control host and a sensor group. Among them, the central control host may be set in the vehicle (that is, the spoiler 1, the side skirt 2 and the diffuser 3 are controlled by the central control host of the vehicle). The central control host can be conductively connected to the spoiler 1, the side skirt 2 and the diffuser 3 through a wire 5. The central control host can control the start, stop and steering of the motor (that is, control the first motor 14, the second motor 26, the third motor 215 and the fourth motor 35) to achieve the control of the motion state of the spoiler 1, the side skirt 2 and the diffuser 3. The sensor group can be installed in the vehicle. The sensor group may include a speed sensor and an acceleration sensor to detect the speed, steering and whether the vehicle is in an acceleration or deceleration state. The sensor group can be conductively connected to the central control host to transmit an electrical signal to the central control host, and the central control host can regulate the spoiler 1, the side skirt 2 and the diffuser 3 according to the current motion state of the vehicle.

[0043] During use, if Figure 5 and Figure 6As shown, the central control host can regulate each spoiler 1, side skirt 2 and diffuser 3 separately. Among them, the spoiler 1 can reduce air resistance. When the vehicle is driving at high speed, the front spoiler 1 can guide the air to the side and bottom of the vehicle, thereby improving the speed and fuel economy of the vehicle. In addition, when the vehicle is driving at high speed, it is easily affected by the side wind and aerodynamic lift, resulting in vehicle instability. The spoiler 1 can offset part of the aerodynamic lift by generating the fourth force, that is, the adhesion to the ground, and control the vehicle to float up, so that the vehicle can drive close to the road, thereby improving the stability of the vehicle. The side skirt 2 can reduce the airflow on both sides of the vehicle body entering the bottom of the vehicle, thereby reducing air resistance and improving the stability and fuel economy of the vehicle. The side skirt 2 also has a certain spoiler effect, especially when the vehicle is driving at high speed, which can help the vehicle remain stable during driving and reduce the risk of drift. The diffuser 3 can comb the airflow at the bottom of the vehicle, allowing the air to pass through the chassis faster, thereby making the air flow rate at the top of the vehicle lower than that at the bottom, so as to generate downforce, so that the vehicle is pressed on the lane by the air, thereby improving the driving stability of the vehicle. The central control host can adjust the spoiler 1, side skirts 2 and diffuser 3 according to different vehicle conditions to keep the vehicle stable.

[0044] In addition, if Figure 7 As shown, according to the second aspect of the present invention, a control method of an aerodynamic component is provided, and the control method of an aerodynamic component is used to control the aerodynamic component for a vehicle as described above. The control method of the aerodynamic component may include: after the vehicle reaches a preset speed, the control component controls the spoiler 1, the side skirt 2 and the diffuser 3, and the central control host controls the start, stop and turn of the first motor 14, the second motor 26, the third motor 215 and the fourth motor 35 according to the detection results of the sensor group. Preferably, the preset speed can be 80km / h, so that the effect of the aerodynamic component for the vehicle can be better exerted.

[0045] Specifically, Figure 7 As shown, in the embodiment, when the vehicle is started, the sensor will detect the speed of the vehicle, and when the speed exceeds the preset speed, the central control host starts to control the movement state of the spoiler 1, the side skirt 2 and the diffuser 3 according to the detection result of the sensor group (i.e. the driving state of the vehicle).

[0046] Further, preferably, Figure 7As shown, in the embodiment, when the vehicle decelerates, the central control host can control the two spoilers 1 to swing downward to increase wind resistance. At the same time, the central control host can control the wing panels 23 of the side skirts 2 to retract to the bottom of the vehicle, and control the blades 31 of the diffuser 3 to return to the normal position (i.e., the length direction of the blades 31 is parallel to the length direction of the vehicle). In this way, the vehicle can maintain stable driving while decelerating.

[0047] Preferably, Figure 7 As shown, in the embodiment, when the vehicle turns left, the central control host can control the spoiler 1 on the left side of the vehicle to swing downward, and control the spoiler 1 on the right side of the vehicle to be parallel to the ground. At the same time, the central control host can control the wing 23 of the side skirt 2 on the left side of the vehicle to extend, and control the wing 23 of the side skirt 2 on the right side of the vehicle to shorten, and control the blade 31 of the diffuser 3 to swing to the left. The specific extension length of the wing 23 of the side skirt 2 can be adaptively adjusted according to the driving speed of the vehicle.

[0048] Similar, such as Figure 7 As shown, in the embodiment, when the vehicle turns right, the central control host can control the spoiler 1 on the right side of the vehicle to swing downward, and control the spoiler 1 on the left side of the vehicle to be parallel to the ground. At the same time, the central control host can control the wing 23 of the side skirt 2 on the right side of the vehicle to extend, and control the wing 23 of the side skirt 2 on the left side of the vehicle to shorten, and control the blade 31 of the diffuser 3 to swing to the right. The specific extension length of the wing 23 of the side skirt 2 can also be adaptively adjusted according to the driving speed of the vehicle.

[0049] During use, the control method of the aerodynamic component can make the spoiler 1, the side skirt 2 and the diffuser 3 cooperate with each other to cope with complex vehicle driving scenarios, so that the vehicle has better stability to further improve the safety of the vehicle.
