Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a spoiler structure, a spoiler assembly, a vortex generator and a vehicle. Background Art

[0002] A spoiler structure is usually set at the bottom of a high-performance sports car. The spoiler structure is used to disturb the air under the body of the car. When the vehicle turns quickly, the negative pressure at the bottom of the body is increased to increase the downforce on the body, thereby improving the vehicle's grip and reducing vehicle slippage or rollover.

[0003] However, when the vehicle is driving on a straight road, the spoiler structure will also increase the downforce of the vehicle, which will increase the vehicle's resistance and is not conducive to increasing the vehicle speed. Summary of the Invention

[0004] The purpose of the present application is to provide a spoiler structure, a spoiler assembly, a vortex generator and a vehicle, aiming to solve the problem that the spoiler structure increases the driving resistance of the vehicle when it is driving on a straight road.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] In a first aspect, the present application provides a spoiler structure, which may include multiple spoilers, each of which is suitable for being rotatably connected to a vehicle; the spoiler structure has a spoiler state and a drag reduction state, and when the spoiler structure is in the spoiler state, the multiple spoilers are sequentially docked to form a spoiler strip for disrupting the airflow at the bottom of the vehicle body; when the spoiler structure is in the drag reduction state, the length direction of the multiple spoilers is consistent with the length direction of the vehicle.

[0007] Through the spoiler structure provided by the present application, when the vehicle turns, the spoiler structure can be put into a spoiler state. At this time, the spoiler strip can block part of the smooth airflow from the front direction of the vehicle, so that the smooth airflow spoiler at the bottom of the vehicle body produces a vortex, thereby generating negative pressure at the bottom of the vehicle body, and then the vehicle body can be subjected to downward pressure (hereinafter referred to as downforce) to increase the vehicle's grip, so as to increase the vehicle's cornering speed.

[0008] When the vehicle is traveling straight ahead, the spoiler structure can be placed in a drag-reducing state. Because the spoiler structure's multiple spoilers are rotatably connected to the vehicle, the spoilers can be rotated to adjust their orientation. When the spoilers are rotated so that their lengths align with the length of the vehicle, the windward surface area of the spoilers is reduced, thereby reducing wind resistance and facilitating increased vehicle speed. Furthermore, when the lengths of the spoilers align with the length of the vehicle, the vehicle's crosswind resistance is enhanced, improving its handling stability.

[0009] In some embodiments, for any two adjacent spoilers, one of the spoilers is located on a side of the other spoiler facing the rear of the vehicle and is located on an outer side of the other spoiler in a width direction of the vehicle.

[0010] In this way, when multiple spoilers are docked to form a spoiler strip, in the width direction of the vehicle, the end of the spoiler strip facing the rear of the vehicle can be located on the outside of the end of the spoiler strip facing the front of the vehicle, so that the spoiler strip can form a shielding plane that intersects with the length direction of the vehicle, thereby blocking the smooth airflow at the bottom of the vehicle body to form a vortex, thereby increasing the negative pressure at the bottom of the vehicle body, increasing the downforce of the vehicle, and improving the vehicle's grip.

[0011] In some embodiments, when the spoiler structure is in the drag reduction state, a flow guide gap extending along the length direction of the vehicle is formed between any two adjacent spoilers along the width direction of the vehicle.

[0012] In this way, when the vehicle is moving straight, the spoiler structure can be placed in a resistance reduction state. At this time, the airflow at the bottom of the vehicle body can flow along the guide gap to the rear of the vehicle, thereby reducing wind resistance and driving resistance.

[0013] In some embodiments, the spoiler includes a spoiler plate, and a thickness direction of the spoiler plate is perpendicular to a height direction of the vehicle.

[0014] The spoiler facilitates the diversion of air beneath the vehicle. When the spoiler structure is in the drag-reducing state, its length aligns with the vehicle's length and its thickness is perpendicular to the vehicle's height. This reduces the spoiler's windward area, thereby reducing driving resistance. Furthermore, when in the drag-reducing state, the spoiler structure enhances the vehicle's crosswind resistance, reduces vehicle roll, and improves vehicle handling stability.

[0015] In some embodiments, the multiple spoilers include a first type of spoiler and a second type of spoiler, the second type of spoiler is located on the side of the first type of spoiler facing the rear of the vehicle and is located on the outside of the first type of spoiler in the width direction of the vehicle; along the direction from the front of the vehicle to the rear of the vehicle, the size of the first type of spoiler in the height direction of the vehicle gradually increases.

[0016] The first type of spoiler is located in the direction closer to the front of the vehicle than the second type of spoiler. The size of the first type of spoiler gradually increases in the height direction of the vehicle. The height of the spoiler structure in the direction of the front of the vehicle is less than the height of the spoiler structure in the direction of the rear of the vehicle. This can increase the ground clearance of the front of the vehicle, thereby effectively improving the vehicle's passability, avoiding the problem of the spoiler structure hitting the ground on a sloping road, and reducing the danger of the vehicle.

[0017] In some embodiments, the first type of spoiler includes a first spoiler and a second spoiler, the second spoiler is located on the side of the first spoiler facing the rear of the vehicle and is located on the outside of the first spoiler in the width direction of the vehicle; along the height direction of the vehicle, the dimension of one end of the first spoiler facing the second spoiler is less than or equal to the dimension of one end of the second spoiler facing the first spoiler.

[0018] The first spoiler is located in a direction where the second spoiler is closer to the front of the vehicle. The dimension of the first spoiler at one end facing the second spoiler is smaller than or equal to the dimension of the second spoiler at one end facing the first spoiler. Since the dimension of the first type of spoiler gradually increases in the height direction of the vehicle, the airflow flows through the first spoiler and the second spoiler in sequence when flowing from the front to the rear of the vehicle. The height from the first spoiler to the second spoiler gradually increases, that is, the shielding effect on the smooth airflow gradually increases, thereby facilitating the formation of vortices and thereby increasing the downforce of the vehicle.

[0019] In some embodiments, the spoiler strip is in an arc-shaped structure, and along the width direction of the vehicle, the concave side of the arc-shaped structure is located outside the convex side of the arc-shaped structure.

[0020] The spoiler is set to an arc-shaped structure, so that the airflow can form a smooth flow path at the bottom of the vehicle body. Along the width direction of the vehicle, the concave side of the arc structure is located on the outside of the convex side of the arc structure, which can prevent the airflow from flowing back to the bottom of the vehicle body and reducing the spoiler effect.

[0021] In some embodiments, a length direction of a spoiler located at the front end of the vehicle in the spoiler strip is consistent with a length direction of the vehicle.

[0022] The length direction of the spoiler located at the front end of the vehicle is consistent with the length direction of the vehicle, which can help the airflow to enter the spoiler area smoothly during the vehicle's driving. Since the rear end of the spoiler is located outside the front end of the spoiler, the spoiler can form a shielding plane that intersects with the length direction of the vehicle. The airflow flowing along the spoiler can be disturbed by the spoiler to form a vortex, thereby forming a negative pressure area at the bottom of the vehicle and increasing the downforce of the vehicle.

[0023] In some embodiments, at least a portion of the spoiler is a flexible material.

[0024] Since the spoiler is arranged at the bottom of the vehicle body, in some road conditions, the bottom of the vehicle body is close to the ground. When the vehicle is traveling at a high speed, the spoiler may hit the ground and cause damage. At least a portion of the spoiler is arranged to be made of flexible material. When the spoiler contacts the ground, at least a portion of the spoiler is deformed, thereby reducing damage to the spoiler.

[0025] In a second aspect, the present application also provides a spoiler assembly, which may include the above-mentioned spoiler structure.

[0026] In some embodiments, the spoiler assembly further includes a transmission member and a driving device, and the driving device is connected to the spoiler structure through the transmission member to switch the spoiler structure between a spoiling state and a drag reduction state.

[0027] In this way, by controlling the drive device, the spoiler structure can be controlled to switch between the spoiler state and the drag reduction state according to different driving conditions of the vehicle, and the vehicle can be adjusted to a state that is conducive to high-speed driving.

[0028] In some embodiments, the transmission member includes a first transmission member and a second transmission member, the first transmission member is connected to the driving device, the second transmission member is connected to the plurality of spoilers, and the first transmission member is in transmission connection with the second transmission member.

[0029] Since the first transmission member is connected to the driving device, the driving device can transmit the driving force to the first transmission member. Since the first transmission member is connected to the second transmission member, the power on the first transmission member can be transmitted to the second transmission member. The second transmission member is connected to multiple spoilers, thereby transmitting power to the multiple spoilers, causing the multiple spoilers to rotate to switch between the spoiler state and the drag reduction state.

[0030] In some embodiments, the first transmission member includes a transmission rod connected to the driving device, and the transmission rod is provided with a transmission groove extending spirally along its axial direction; the second transmission member includes multiple transmission plates, and the transmission plates are provided with multiple transmission teeth arranged at intervals along their circumference. The transmission teeth cooperate with the transmission groove for transmission, and one transmission plate is connected to a spoiler.

[0031] By providing a transmission groove extending helically along the axial direction of the transmission rod and a plurality of transmission teeth spaced circumferentially on the transmission disc, the transmission teeth cooperate with the transmission groove to effectively transmit the power of the drive device to the spoiler, causing the spoiler to rotate, thereby enabling the spoiler structure to switch between a flow-disturbing state and a drag-reducing state. The coordinated transmission of the transmission teeth and the transmission groove makes the transmission process more stable, and by controlling the transmission ratio of the transmission teeth to the transmission groove, the rotation angle of the spoiler can be more precisely controlled.

[0032] In addition, a transmission rod can be used to cooperate with multiple transmission discs, and each transmission disc controls a spoiler. In this way, only one driving device is needed to drive multiple spoilers, which is more convenient to operate and has a simpler structure. In some embodiments, the spoiler assembly further includes a connecting member connected between the spoiler and the transmission disc.

[0033] The connecting piece can facilitate the connection between the spoiler and the transmission plate, so that the spoiler is not restricted by the position of the transmission piece, so as to more reasonably utilize the vehicle space.

[0034] In some embodiments, the spoiler includes a first end portion and a second end portion arranged along a length direction of the vehicle, and the connecting member is connected to the first end portion and the second end portion.

[0035] The connecting piece can be connected to the first end and the second end, so that the stability of the spoiler connection can be enhanced, and the deflection and swing caused by the airflow passing through the spoiler can be reduced, so that the airflow under the vehicle body can be stably guided.

[0036] In some embodiments, the connecting member further includes a base, the spoiler is fixedly connected to the base, and the base is fixedly connected to the connecting member.

[0037] The spoiler and the connecting piece are connected via the base, so that the spoiler and the connecting piece are fixedly connected, thereby enhancing the connection strength between the spoiler and the connecting piece.

[0038] In a third aspect, the present application also provides a vortex generator, which may include the above-mentioned spoiler assembly.

[0039] In some embodiments, the vortex generator includes a plurality of spoilers arranged along the length direction of the vehicle; the spoiler includes at least one spoiler assembly.

[0040] Since the spoiler includes at least one spoiler assembly, and since the spoiler assembly can disrupt the airflow at the bottom of the vehicle body to increase the downforce of the vehicle, multiple spoilers are arranged along the length of the vehicle, which can further disrupt the air at the bottom of the vehicle body, thereby enhancing the downforce of the vehicle and facilitating the vehicle to increase cornering speed.

[0041] In some embodiments, the spoiler device includes a first spoiler component and a second spoiler component, and the first spoiler component and the second spoiler component are symmetrically arranged relative to the length direction of the vehicle.

[0042] The first spoiler assembly and the second spoiler assembly are symmetrically arranged with the longitudinal direction of the vehicle as the symmetry axis, so that the smooth airflow located at the first spoiler assembly and the second spoiler assembly can be blocked, thereby forming a vortex in the airflow spoiler at the bottom of the vehicle body. In this way, the air spoiler at the bottom of the vehicle body can be made more uniform, thereby generating negative pressure at the first spoiler assembly and the second spoiler assembly, reducing the vehicle tilt caused by uneven downforce.

[0043] In some embodiments, when the vehicle is traveling straight and the vehicle's speed is greater than a first preset speed, if the vehicle is traveling at a constant speed, the spoiler structures are controlled to switch to a drag reduction state.

[0044] When the vehicle is traveling straight at high speed, wind resistance has a greater impact on the vehicle's speed. The spoiler structures are all switched to a resistance reduction state. The length direction of multiple spoilers is consistent with the length direction of the vehicle, which can reduce the vehicle's frontal area, thereby reducing wind resistance and allowing the vehicle to maintain high-speed driving.

[0045] In some embodiments, the spoiler device includes a first spoiler device and a second spoiler device, and the second spoiler device is located on the side of the first spoiler device facing the rear of the vehicle; if the vehicle accelerates, the first spoiler device is controlled to switch to the spoiler state, and the second spoiler device is switched to the drag reduction state; if the vehicle decelerates, the first spoiler device is controlled to switch to the drag reduction state, and the second spoiler device is switched to the spoiler state.

[0046] When the vehicle accelerates, switching the first spoiler to the spoiler mode and the second spoiler to the drag reduction mode increases downforce on the front of the vehicle, mitigating nose-up during acceleration. This increased downforce on the front of the vehicle also improves grip on the front wheels, shortening acceleration time. When the vehicle decelerates, switching the first spoiler to the drag reduction mode and the second spoiler to the spoiler mode increases downforce on the rear of the vehicle, mitigating tail-up during deceleration and ultimately reducing braking distance.

[0047] In some embodiments, when the vehicle's driving speed is less than a first preset speed and greater than a second preset speed, and is traveling at a constant speed, wherein the second preset speed is less than the first preset speed; if the vehicle turns right and the steering angle is less than the first preset angle, the spoiler assembly on the left side of the multiple spoiler devices is controlled to switch to a spoiling state, and the spoiler assembly on the right side of the multiple spoiler devices is controlled to switch to a drag reduction state; if the vehicle turns left and the steering angle is less than the first preset angle, the spoiler assembly on the right side of the multiple spoiler devices is controlled to switch to a spoiling state, and the spoiler assembly on the left side of the multiple spoiler devices is controlled to switch to a drag reduction state.

[0048] In some embodiments, when the vehicle's driving speed is less than a first preset speed and greater than a second preset speed, and the vehicle is accelerating, if the vehicle turns right and the steering angle is less than the first preset angle, the spoiler component on the left side of the first spoiler device is controlled to switch to a spoiling state, and the spoiler component on the right side of the first spoiler device and the second spoiler device are switched to a drag reduction state; if the vehicle turns left and the steering angle is less than the first preset angle, the spoiler component on the right side of the first spoiler device is controlled to switch to a spoiling state, and the spoiler component on the left side of the first spoiler device and the second spoiler device are switched to a drag reduction state.

[0049] In some embodiments, when the vehicle's driving speed is less than the first preset speed and greater than the second preset speed, and the vehicle is decelerating, if the vehicle turns right and the steering angle is less than the first preset angle, the spoiler component on the left side of the second spoiler device is controlled to switch to the spoiling state, and the spoiler component on the right side of the second spoiler device and the first spoiler device are switched to the drag reduction state; if the vehicle turns left and the steering angle is less than the first preset angle, the spoiler component on the right side of the second spoiler device is controlled to switch to the spoiling state, and the spoiler component on the left side of the second spoiler device and the first spoiler device are switched to the drag reduction state.

[0050] In some embodiments, when the vehicle turns, the vehicle's driving speed is less than a second preset speed, and the steering angle is greater than a first preset angle, the plurality of spoiler components are controlled to switch to a spoiler state.

[0051] In a fourth aspect, the present application also provides a vehicle, which may include the above-mentioned spoiler structure, spoiler assembly or vortex generator.

[0052] It should be noted that the technical effects brought about by the implementation methods of the second to fourth aspects can all refer to the technical effects brought about by the corresponding implementation methods in the first aspect, and will not be repeated here.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0073] The present application provides a vehicle 1000. Vehicle 1000 may be a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, an extended-range electric vehicle, a gasoline vehicle, etc. Vehicle 1000 may also be a racing car, a sedan, a van, a bus, a truck, a trailer, etc.

[0074] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in an embodiment of the present application. Vehicle 1000 includes a body 100 and wheels 200. Body 100 is used for seating passengers and carrying items. Wheels 200 are mounted beneath body 100 to support body 100 and are capable of rolling on the road to enable vehicle 1000 to travel.

[0075] Please refer to Figure 2 , Figure 2 for Figure 1 The bottom structure diagram of the vehicle 1000 is shown. In order to improve the safety of the vehicle 1000 when traveling at high speed, the vehicle 1000 is provided with a vortex generator 300. The vortex generator 300 is provided at the bottom of the vehicle body 100.

[0076] The vortex generator 300 includes a spoiler assembly 320. The spoiler assembly 320 is used to spoil the airflow at the bottom of the vehicle body 100, so as to increase the negative pressure at the bottom of the vehicle body 100 and improve the grip of the vehicle body 100.

[0077] In some embodiments, the spoiler assembly 320 may include a spoiler structure 330. Figure 2 and Figure 3 , Figure 3 This is a structural schematic diagram of a spoiler assembly 320 in a spoiler state provided in an embodiment of the present application. The spoiler structure 330 may include a plurality of spoilers 331 , and the plurality of spoilers 331 are all suitable for being rotatably connected to the vehicle 1000 .

[0078] The spoiler structure 330 can have a spoiler state. When the spoiler structure 330 is in the spoiler state, the plurality of spoilers 331 are connected in sequence to form a spoiler strip 332 for spoiling the smooth airflow at the bottom of the vehicle body 100 .

[0079] Please refer to Figure 2 Specifically, when the vehicle 1000 is driving, air will enter the bottom of the vehicle body 100 from the front 110 of the vehicle 1000 and flow toward the rear 120. The spoiler strip 332 is provided at the bottom of the vehicle body 100. When the air from the bottom of the vehicle body 100 flows toward the rear 120, part of the smooth airflow will be blocked by the spoiler strip 332.

[0080] In this way, this part of the blocked airflow will generate vortices during the flow, thereby generating negative pressure at the bottom of the vehicle body 100, which in turn can cause the vehicle body 100 to be subjected to downward pressure to increase the grip of the vehicle 1000, so as to increase the cornering speed of the vehicle 1000.

[0081] However, when the vehicle 1000 is traveling on a straight road, the vehicle 1000 is not prone to rollover or tailspin, and does not require much grip. However, the spoiler strip 332 will increase the frontal area of the vehicle 1000, thereby increasing wind resistance, which is not conducive to accelerating the vehicle 1000.

[0082] Because the plurality of spoilers 331 of the spoiler structure 330 are rotatably connected to the vehicle 1000, the spoilers 331 can be rotated to adjust the orientation of the spoilers 331 and reduce the windward surface area of the spoilers 331. The windward surface of the spoilers 331 refers to the surface of the spoilers 331 that faces the front end 110 when the vehicle 1000 is traveling.

[0083] Please refer to Figure 4 and Figure 5 , Figure 4 for Figure 3 The structure diagram of the spoiler assembly 320 shown is in a drag reduction state. Figure 5 for Figure 2 The vehicle 1000 shown is a structural schematic diagram showing that the spoiler components 320 are all in a drag reduction state. The spoiler structure 330 provided in the present application can also have a drag reduction state. When the spoiler structure 330 is in the drag reduction state, the length direction of the multiple spoilers 331 is consistent with the length direction of the vehicle 1000.

[0084] When the vehicle 1000 is traveling straight, the spoiler structure 330 can be placed in a resistance reduction state. At this time, the spoiler 331 rotates until its length direction is consistent with the length direction of the vehicle 1000, and the area of the windward surface of the spoiler 331 is reduced, thereby reducing the wind resistance of the vehicle 1000 and facilitating an increase in vehicle speed.

[0085] In addition, since the length direction of the multiple spoilers 331 is consistent with the length direction of the vehicle, no spoiler strips 332 will be formed. Therefore, no negative pressure area will be formed at the bottom of the vehicle body 100 due to the spoiler strips 332 blocking the smooth airflow, and the vehicle 1000's grip will be reduced, thereby reducing driving resistance.

[0086] At the same time, when the length direction of the spoiler 331 is consistent with the length direction of the vehicle 1000, the vehicle 1000 can enhance its ability to resist crosswinds, reduce the roll of the vehicle 1000, and increase the handling stability of the vehicle 1000.

[0087] For example, the size of the spoiler 331 along the height direction of the vehicle 1000 can be 30 mm to 60 mm, for example, the size of the spoiler 331 along the height direction of the vehicle 1000 can be 30 mm, 35 mm, 40 mm, 42 mm, 45 mm, 50 mm, or 60 mm, etc., and this size can be adjusted according to the distance between the bottom of the vehicle body 100 and the ground. The size of the spoiler 331 along the length direction of the vehicle 1000 can be 15 mm to 100 mm, for example, the size of the spoiler 331 along the length direction of the vehicle 1000 can be 15 mm, 20 mm, 30 mm, 50 mm, or 100 mm, etc., and this size can be adjusted according to the size of the vehicle body 100. The size of the spoiler strip 332 along the length direction of the vehicle 1000 can be 800mm~1000mm. For example, the size of the spoiler strip 332 along the length direction of the vehicle 1000 can be 800mm, 850mm, 900mm or 1000mm, etc. The size can also be adjusted according to the size of the vehicle body 100, and this application does not make further restrictions on this.

[0088] Please refer to Figure 2 and Figure 5 In some embodiments, for any two adjacent spoilers 331 , one spoiler 331 is located on the side of the other spoiler 331 facing the rear end 120 and is located on the outside of the other spoiler 331 in the width direction of the vehicle 1000 .

[0089] In this way, when multiple spoilers 331 are docked to form a spoiler strip 332, in the width direction of the vehicle 1000, the end of the spoiler strip 332 facing the rear end 120 can be located on the outside of the end of the spoiler strip 332 facing the front end 110, so that the spoiler strip 332 can form a blocking plane that intersects with the length direction of the vehicle 1000, thereby blocking the smooth airflow at the bottom of the vehicle body 100 to form a vortex, thereby increasing the negative pressure at the bottom of the vehicle body 100, increasing the downforce of the vehicle 1000, and improving the grip of the vehicle 1000.

[0090] It can be understood that in the width direction of the vehicle 1000, the body 100 includes a first end and a second end, and the area between the first end and the second end is the middle part of the body 100. Then, the side of the first end facing away from the middle part of the body 100 is the outside of the vehicle 1000, and the side of the second end facing away from the middle part of the body 100 can also be the outside of the vehicle 1000.

[0091] Please continue to refer to Figure 5 In some embodiments, when the spoiler structure 330 is in the drag reduction state, a guide gap 130 extending along the length direction of the vehicle 1000 may be formed between any two adjacent spoilers 331 along the width direction of the vehicle 1000 .

[0092] In this way, when the vehicle 1000 is traveling straight, the spoiler structure 330 can be placed in a resistance reduction state, and the airflow at the bottom of the vehicle body 100 can flow along the guide gap 130 to the rear end 120, thereby reducing wind resistance and driving resistance.

[0093] Please continue to refer to Figure 3 and Figure 4 In some embodiments, the spoiler 331 may include a spoiler 331A, and the thickness direction of the spoiler 331A is perpendicular to the height direction of the vehicle 1000.

[0094] The spoiler 331A can facilitate the diversion of air under the vehicle. When the spoiler structure 330 is in the resistance reduction state, since the length direction of the spoiler 331A is consistent with the length direction of the vehicle 1000, and the thickness direction of the spoiler 331A is perpendicular to the height direction of the vehicle 1000, when the vehicle 1000 is driving, the windward surface area of the spoiler 331A is smaller, the wind resistance is smaller, and it is not easy to block the smooth airflow at the bottom of the vehicle body 100 to form vortices, which makes the vehicle 1000 have less grip, thereby reducing the driving resistance of the vehicle 1000.

[0095] At the same time, the spoiler 331A can enhance the vehicle 1000's ability to resist crosswinds, reduce the vehicle 1000's roll, and increase the vehicle 1000's handling stability.

[0096] In some other embodiments, the spoiler 331 may also be a block-shaped structure, a rod-shaped structure, a blade-shaped structure, an irregular structure, etc.

[0097] In some embodiments, the plurality of spoilers 331 include a first type of spoiler and a second type of spoiler, wherein the second type of spoiler is located on the side of the first type of spoiler facing the rear end 120 and is located on the outside of the first type of spoiler in the width direction of the vehicle 1000; along the direction from the front end 110 to the rear end 120, the size of the first type of spoiler in the height direction of the vehicle 1000 gradually increases.

[0098] The first type of spoiler is located in the direction closer to the front end 110 of the vehicle than the second type of spoiler. The size of the first type of spoiler gradually increases in the height direction of the vehicle 1000. The height of the spoiler structure 330 in the direction of the front end 110 is less than the height of the spoiler structure 330 in the direction of the rear end 120. This can increase the ground clearance of the front end 110, thereby effectively improving the passability of the vehicle 1000, avoiding the problem of the spoiler structure 330 hitting the ground on a sloping road, and reducing the danger of the vehicle 1000.

[0099] In some embodiments, the first type of spoiler may include a first spoiler 3311 and a second spoiler 3312, the second spoiler 3312 being located on the side of the first spoiler 3311 facing the rear end 120 and being located on the outside of the first spoiler 3311 in the width direction of the vehicle 1000; along the height direction of the vehicle 1000, the dimension of one end of the first spoiler 3311 facing the second spoiler 3312 is less than or equal to the dimension of one end of the second spoiler 3312 facing the first spoiler 3311.

[0100] The first spoiler 3311 is located in the direction where the second spoiler 3312 is close to the front end 110 of the vehicle. The size of the first spoiler 3311 at one end facing the second spoiler 3312 is less than or equal to the size of the second spoiler 3312 at one end facing the first spoiler 3311. Since the size of the first type of spoiler gradually increases in the height direction of the vehicle 1000, when the airflow flows from the front end 110 to the rear end 120, it flows through the first spoiler 3311 and the second spoiler 3312 in sequence. The height direction from the first spoiler 3311 to the second spoiler 3312 gradually increases, that is, the shielding effect on the smooth airflow gradually increases, which helps to form vortices and thereby increases the downforce of the vehicle 1000.

[0101] In some embodiments, the first spoiler 3311 and the second spoiler 3312 may be two adjacent spoilers 331, and the dimension of the end of the first spoiler 3311 facing the second spoiler 3312 may be equal to the dimension of the end of the second spoiler 3312 facing the first spoiler 3311. In this way, the height gradually increases from the first spoiler 3311 to the second spoiler 3312, and no bulge in the height direction is formed, thereby reducing unnecessary resistance.

[0102] In some embodiments, a third spoiler may be provided between the first spoiler 3311 and the second spoiler 3312. The third spoiler may be a first type of spoiler or a second type of spoiler. The size of the end of the first spoiler 3311 facing the second spoiler 3312 may be smaller than the size of the end of the second spoiler 3312 facing the first spoiler 3311.

[0103] Please refer to Figure 2 and Figure 3 In some embodiments of the present application, when the spoiler structure 330 is in the spoiler state, the spoiler strip 332 may be an arc-shaped structure, and along the width direction of the vehicle 1000, the concave side of the arc-shaped structure is located outside the convex side of the arc-shaped structure.

[0104] The spoiler strip 332 is set to an arc-shaped structure, and the airflow can form a smooth flow path at the bottom of the vehicle body 100. Along the width direction of the vehicle 1000, the concave side of the arc structure is located on the outside of the convex side of the arc structure, which can avoid the airflow flowing back to the bottom of the vehicle body 100 and reduce the spoiler effect.

[0105] In some embodiments, the length direction of the spoiler 331 located at the front end of the vehicle 1000 in the spoiler strip 332 is consistent with the length direction of the vehicle 1000 .

[0106] The spoiler strip 332 is located at the front end of the vehicle 1000, and the length direction of the spoiler 331 is consistent with the length direction of the vehicle 1000, which can help the airflow to smoothly enter the spoiler area during the driving of the vehicle 1000. Since the rear end 120 of the spoiler strip 332 is located on the outside of the front end 110 of the spoiler strip 332, the spoiler strip 332 can form a blocking plane that intersects with the length direction of the vehicle 1000. The airflow flowing along the spoiler 331 can be disturbed by the spoiler strip 332 to form a vortex, thereby forming a negative pressure area at the bottom of the vehicle 1000, thereby increasing the downforce of the vehicle 1000.

[0107] In some embodiments, at least a portion of the spoiler 331 is made of a flexible material. Because the spoiler 331 is disposed at the bottom of the vehicle body 100, in some road conditions, the bottom of the vehicle body 100 is relatively close to the ground. When the vehicle 1000 is traveling at a high speed, the spoiler 331 may strike the ground and cause damage. Since at least a portion of the spoiler 331 is made of a flexible material, at least a portion of the spoiler 331 deforms when it contacts the ground, thereby reducing damage to the spoiler 331.

[0108] For example, the side of the spoiler 331 close to the ground may be made of a flexible material; the entire spoiler 331 may also be made of a flexible material.

[0109] Exemplarily, the flexible material may be a soft rubber material, for example, the flexible material may be silicone, rubber, thermoplastic elastomer, thermoplastic polyurethane or polyvinyl chloride plastic, etc., and this application does not make any further limitations on this.

[0110] In addition, the spoiler 331 is configured to be made of a flexible material, which can form a buffer between the bottom of the vehicle 1000 and the ground, thereby reducing the falling of parts of the vehicle 1000 due to bottom collision, and further reducing the malfunction or loss of control of the vehicle 1000 caused by the falling of parts.

[0111] At the same time, the spoiler 331 is made of flexible material, and if it accidentally falls off, it can reduce the damage caused by the impact on surrounding people or equipment when it flies out.

[0112] Please refer to Figure 3 and Figure 4 In some embodiments, the spoiler assembly 320 may further include a transmission member 350 and a drive device 340. The drive device 340 is connected to the spoiler structure 330 through the transmission member 350 to enable the spoiler structure 330 to switch between a spoiler state and a drag reduction state.

[0113] In this way, by controlling the driving device 340, the spoiler structure 330 can be controlled to switch between the spoiler state and the drag reduction state according to different driving states of the vehicle 1000, so as to adjust the vehicle 1000 to a state conducive to high-speed driving.

[0114] In some embodiments, since the spoiler structure 330 includes multiple spoilers 331, in order to control the rotation of the multiple spoilers 331, the spoiler assembly 320 may include multiple driving devices 340 and multiple transmission members 350. The multiple driving devices 340, the multiple transmission members 350 and the multiple spoilers 331 correspond one to one, so that the rotation of the multiple spoilers 331 is controlled by controlling the multiple driving devices 340, thereby switching the spoiler structure 330 between the spoiler state and the drag reduction state.

[0115] In order to simplify the number and structure of components of the vehicle 1000, in some embodiments, multiple spoilers 331 can be driven by a driving device 340, and the power output by the driving device 340 is transmitted to different spoilers 331 through a transmission member 350 to rotate the spoilers 331, thereby switching the spoiler structure 330 between a spoiling state and a drag reduction state.

[0116] Please continue to refer to Figure 3 and Figure 4 In some embodiments, the transmission member 350 may include a first transmission member 351 and a second transmission member 352, the first transmission member 351 is connected to the driving device 340, the second transmission member 352 is connected to the plurality of spoilers 331, and the first transmission member 351 and the second transmission member 352 are in transmission connection.

[0117] Since the first transmission member 351 is connected to the driving device 340, the driving device 340 can transmit the driving force to the first transmission member 351. Since the first transmission member 351 is connected to the second transmission member 352, the power on the first transmission member 351 can be transmitted to the second transmission member 352. The second transmission member 352 is connected to multiple spoilers 331, thereby transmitting power to the multiple spoilers 331, causing the multiple spoilers 331 to rotate to switch between the spoiler state and the drag reduction state.

[0118] In a possible structural design, the second transmission member 352 can be configured as multiple transmission members, each of which corresponds to a plurality of spoilers 331 , thereby switching the spoiler structure 330 between a spoiling state and a drag reduction state.

[0119] In some embodiments, the first transmission member 351 may include a transmission rod 351A connected to the driving device 340, and the transmission rod 351A is provided with a transmission groove extending spirally along its axial direction; the second transmission member 352 includes multiple transmission disks 352A, and the transmission disk 352A is provided with multiple transmission teeth arranged at intervals along its circumference, and the transmission teeth cooperate with the transmission groove for transmission, and a transmission disk 352A is connected to a spoiler 331.

[0120] By providing a transmission groove extending spirally along its axial direction on the transmission rod 351A, and providing a plurality of transmission teeth arranged at intervals along its circumference on the transmission disk 352A, the transmission teeth can cooperate with the transmission groove for transmission, and the power of the driving device 340 can be effectively transmitted to the spoiler 331, so that the spoiler 331 rotates, thereby allowing the spoiler structure 330 to switch between the spoiling state and the drag reduction state.

[0121] The transmission teeth and the transmission groove cooperate for transmission. By adjusting the transmission ratio of different transmission plates 352A and the transmission rod 351A, when the transmission rod 351A rotates, the transmission groove rotates the same distance, and different transmission plates 352A can rotate at different angles, so that the multiple spoilers 331 can rotate at different angles, so that the spoilers 331 located at different positions can be connected to form a smooth spoiler strip 332. In this way, the transmission process can be made more stable through the cooperation between the transmission teeth and the transmission groove, and the rotation angle of the spoiler 331 can be made more precise by controlling the transmission ratio of the transmission teeth and the transmission groove.

[0122] In addition, since the contact form between the transmission teeth and the transmission groove is mainly sliding friction, when the transmission rod is rotated to a fixed position, the friction can prevent the transmission disc from driving the transmission rod in the reverse direction. Therefore, when the transmission rod is rotated to a fixed position, the transmission disc can be driven to rotate a specified angle, thereby causing the spoiler to rotate to a specified angle, so that the spoiler structure switches between the turbulence state and the resistance reduction state. Since the transmission disc cannot reversely drive the transmission rod to rotate, when the spoiler is disturbed by the airflow, it will not drive the transmission disc and the transmission rod to rotate, thereby preventing the spoiler from shifting and causing the turbulence state or the resistance reduction state to fail. In some embodiments, the transmission rod 351A may include a worm, and the transmission disc 352A may include a worm wheel. The worm and the worm wheel are provided with mutually cooperating transmission teeth, so that the worm wheel and the worm are engaged, and the power of the drive device 340 is transmitted to the spoiler 331 through the worm and the worm wheel in sequence.

[0123] In other embodiments, the transmission rod 351A may include a screw, and for example, the screw may be a ball screw. The transmission teeth on the transmission disc 352A need to match the ball screw's raceway, and the balls roll between the screw's raceway and the tooth grooves of the transmission teeth to achieve the conversion between the screw's rotational motion and the linear motion or rotational motion of the transmission disc 352A, thereby enabling high-precision and high-efficiency power transmission. In some embodiments, the spoiler assembly 320 may further include a connector 360, which is connected between the spoiler 331 and the transmission disc 352A. The connector 360 can facilitate the connection between the spoiler 331 and the transmission disc 352A, thereby allowing the spoiler 331 to be free from the positional restrictions of the transmission member 350, so as to more rationally utilize the space of the vehicle 1000.

[0124] In some embodiments, the spoiler 331 may include a first end portion and a second end portion arranged along the length direction of the vehicle 1000 , and the connector 360 is connected to the first end portion and the second end portion.

[0125] The connecting member 360 can be connected to the first end and the second end, so that the stability of the connection of the spoiler 331 can be enhanced, and the deflection and swing caused by the airflow passing through the spoiler 331 can be reduced, so that the airflow at the bottom of the vehicle body 100 can be stably guided.

[0126] In some embodiments, the connector 360 may include a first connector and a second connector, wherein the first connector is connected to the first end, and the second connector is connected to the second end, so that the two ends of the spoiler 331 can be fixedly connected to prevent the spoiler 331 from being deflected due to airflow disturbance.

[0127] In a possible structural design, the connecting member 360 may include a first rod portion, a second rod portion and a connecting portion, the first rod portion and the second rod portion are respectively connected to the two ends of the connecting portion, and the first rod portion is connected to the first end portion, and the second rod portion is connected to the second end portion, so that the two ends of the spoiler 331 can be fixedly connected to prevent the spoiler 331 from being deflected due to airflow disturbance.

[0128] In another possible structural design, the connecting member 360 may include a connecting plate or a connecting block, which may be connected to the first end and the second end, or may be completely connected to the surface of the spoiler 331 facing the connecting member 360 to increase the connection strength of the spoiler 331.

[0129] Please refer to Figure 3 and Figure 6 , Figure 6 for Figure 3 As shown in a partial schematic diagram of the spoiler assembly 320 , in some embodiments, the connecting member 360 may include a base 370 , the spoiler 331 is fixedly connected to the base 370 , and the base 370 is fixedly connected to the connecting member 360 .

[0130] Connecting the spoiler 331 and the connecting member 360 via the base 370 can facilitate fixed connection between the spoiler 331 and the connecting member 360 , thereby enhancing the connection strength between the spoiler 331 and the connecting member 360 .

[0131] For example, the spoiler 331 is made of silicone and the connector 360 is made of metal, so the two cannot be directly connected by welding. A base 370 is introduced to connect between the spoiler 331 and the connector 360. The spoiler 331 can be riveted to the base 370 by rivets, and then the base 370 and the connector 360 are welded and fixed. In this way, the spoiler 331 can be fixedly connected to the connector 360, reducing the interference of airflow on the stability of the spoiler 331.

[0132] Please continue to refer to Figure 2 In some embodiments, the vortex generator 300 may include one spoiler assembly 320 or a plurality of spoiler assemblies 320 .

[0133] In some examples, the vortex generator 300 includes a plurality of spoilers 310 , which are arranged along the length of the vehicle 1000 . The spoiler 310 may include at least one spoiler assembly 320 .

[0134] Since the spoiler 310 includes at least one spoiler assembly 320, and since the spoiler assembly 320 can interfere with the smooth airflow at the bottom of the vehicle body 100 to form a vortex to increase the negative pressure at the bottom of the vehicle body, thereby increasing the downforce of the vehicle 1000, therefore, multiple spoilers 310 are arranged along the length direction of the vehicle 1000, which can further disturb the air at the bottom of the vehicle body 100, thereby further enhancing the downforce of the vehicle 1000 and facilitating the vehicle 1000 to increase its cornering speed.

[0135] In one possible structural design, the vortex generator 300 may include two spoilers 310, which are respectively disposed on the rear side of the front suspension and the front side of the rear suspension at the bottom of the vehicle 1000. In another possible structural design, the vortex generator 300 may include three spoilers 310, which are respectively disposed on the rear side of the front suspension, the front side of the battery pack, and the front side of the rear suspension at the bottom of the vehicle 1000.

[0136] In some embodiments, the spoiler device 310 includes a first spoiler component 320A and a second spoiler component 320B. The first spoiler component 320A and the second spoiler component 320B are symmetrically arranged with respect to the length direction of the vehicle 1000 .

[0137] The first spoiler assembly 320A and the second spoiler assembly 320B are symmetrically arranged with the longitudinal direction of the vehicle 1000 as the axis of symmetry, so that the smooth airflow located at the first spoiler assembly 320A and the second spoiler assembly 320B can be blocked, thereby forming a vortex in the airflow turbulence at the bottom of the vehicle body 100. In this way, the air turbulence at the bottom of the vehicle body 100 can be made more uniform, and negative pressure can be generated at the first spoiler assembly 320A and the second spoiler assembly 320B, thereby reducing the tilt of the vehicle 1000 caused by uneven downforce.

[0138] In addition, since the first spoiler component 320A and the second spoiler component 320B can be switched between a spoiler state and a drag reduction state, the downforce on both sides of the vehicle 1000 when the vehicle 1000 turns can be adjusted by adjusting the state of the first spoiler component 320A and the second spoiler component 320B, thereby reducing the occurrence of unexpected situations such as the vehicle 1000 rolling over when turning.

[0139] In some embodiments, when the vehicle 1000 is traveling straight and the speed of the vehicle 1000 is greater than a first preset speed, if the vehicle 1000 is traveling at a constant speed, the spoiler structures 330 are controlled to switch to a resistance reduction state.

[0140] When the vehicle 1000 is traveling straight at high speed, the wind resistance has a greater impact on the speed of the vehicle 1000. The spoiler structures 330 are all switched to the resistance reduction state. The length direction of the multiple spoilers 331 is consistent with the length direction of the vehicle 1000, which can reduce the windward area of the vehicle 1000, thereby reducing the wind resistance and allowing the vehicle 1000 to maintain high-speed driving.

[0141] Exemplarily, the first preset speed may be 180 km / h, 190 km / h or 200 km / h. When the vehicle speed is higher than the first preset speed, it can be understood that the vehicle 1000 is traveling at a high speed.

[0142] The vehicle 1000 going straight can be understood as the length direction of the vehicle 1000 and the extension direction of the straight section completely coinciding. The vehicle 1000 going straight can also be understood as the length direction of the vehicle 1000 and the extension direction of the straight section having a small angle (named as the deflection angle). Exemplarily, when the vehicle 1000 goes straight, the deflection angle of the vehicle 1000 can be 0° to 0.5°. For example, when the vehicle 1000 goes straight, the deflection angle of the vehicle 1000 can be 0°, 0.2° or 0.5°, etc.

[0143] In some embodiments, the spoiler 310 includes a first spoiler 310A and a second spoiler 310B, and the second spoiler 310B is located on the side of the first spoiler 310A facing the rear end 120; if the vehicle 1000 accelerates, the first spoiler 310A is controlled to switch to the spoiling state, and the second spoiler 310B is switched to the resistance reduction state; if the vehicle 1000 decelerates, the first spoiler 310A is controlled to switch to the resistance reduction state, and the second spoiler 310B is switched to the spoiling state.

[0144] For example, when the acceleration of the vehicle 1000 is greater than or equal to 0.05 times the acceleration due to gravity, it can be understood that the vehicle 1000 is in an accelerating state. For example, the acceleration of the vehicle 1000 is 0.5 m / s. 2 , 0.6m / s 2 or 0.8m / s 2 , the vehicle 1000 is in an accelerating state.

[0145] For example, when the acceleration of the vehicle 1000 is less than or equal to -0.05 times the acceleration due to gravity, it can be understood that the vehicle 1000 is in a deceleration state. For example, the acceleration of the vehicle 1000 is -0.5 m / s 2 、-0.6m / s 2 or -0.8m / s 2 , the vehicle 1000 is in a decelerating state.

[0146] When the vehicle 1000 accelerates, the second spoiler 310B is located on the side of the first spoiler 310A facing the rear end 120, so the first spoiler 310A is located at the front of the vehicle 1000 and the second spoiler 310B is located at the rear of the vehicle 1000. Switching the first spoiler 310A to the spoiling state and the second spoiler 310B to the drag reduction state increases the downforce on the front of the vehicle 1000, thereby reducing the upward tilt of the front end 110 during acceleration of the vehicle 1000. At the same time, the increased downforce on the front of the vehicle 1000 increases the grip of the front wheels of the vehicle 1000, thereby shortening the acceleration time.

[0147] When the vehicle 1000 decelerates, the rear end of the vehicle 1000 may rush forward due to inertia, causing the rear end 120 to tilt upward. Switching the first spoiler 310A to the drag reduction state and the second spoiler 310B to the spoiler state can increase the downforce on the rear section of the vehicle 1000, thereby reducing the tilting of the rear end 120 when the vehicle 1000 decelerates, and thus shortening the braking distance.

[0148] Please refer to Figure 7 , Figure 7 for Figure 2The structure diagram of the vehicle 1000 shown is a diagram of a single-side spoiler assembly 320 in a drag reduction state. In some embodiments, when the driving speed of the vehicle 1000 is less than a first preset speed and greater than a second preset speed, and is traveling at a constant speed, wherein the second preset speed is less than the first preset speed; if the vehicle 1000 turns right and the deflection angle is less than the first preset angle, the spoiler assembly 320 on the left side of the multiple spoiler devices 310 is controlled to switch to the spoiling state, and the spoiler assembly 320 on the right side of the multiple spoiler devices 310 is switched to the drag reduction state; if the vehicle 1000 turns left and the deflection angle is less than the first preset angle, the spoiler assembly 320 on the right side of the multiple spoiler devices 310 is controlled to switch to the spoiling state, and the spoiler assembly 320 on the left side of the multiple spoiler devices 310 is switched to the drag reduction state.

[0149] When the speed of vehicle 1000 is less than the first preset speed and greater than the second preset speed, vehicle 1000 is traveling at a relatively high speed. For example, the second preset speed may be 140 km / h, 145 km / h, or 150 km / h. When vehicle 1000 is traveling in this speed range, a deviation in the direction of travel of vehicle 1000 may cause vehicle body 100 on the opposite side of the turning direction to tilt upward, thereby easily causing vehicle 1000 to roll.

[0150] Exemplarily, the first preset angle can be 2°. Since when the deflection angle of vehicle 1000 is 0°~0.5°, vehicle 1000 is considered to be moving straight. Therefore, when the deflection angle of vehicle 1000 is 0.5°~2°, it can be understood that the driving direction of vehicle 1000 is deflected. For example, the deflection angle of vehicle 1000 is 0.5°, 0.8°, 1.2°, 1.5° or 2°.

[0151] Therefore, if the vehicle 1000 turns right and the deflection angle is less than the first preset angle, the spoiler assembly 320 located on the left side of the multiple spoiler devices 310 is controlled to switch to the spoiler state, and the spoiler assembly 320 located on the right side of the multiple spoiler devices 310 is switched to the drag reduction state. In this way, the downforce on the left side of the vehicle 1000 is increased, thereby increasing the grip of the left side of the vehicle 1000 and preventing the vehicle 1000 from rolling over when turning right.

[0152] If the vehicle 1000 turns left and the deflection angle is less than the first preset angle, the spoiler assembly 320 on the right side of the multiple spoiler devices 310 is controlled to switch to the spoiler state, and the spoiler assembly 320 on the left side of the multiple spoiler devices 310 is switched to the drag reduction state. In this way, the downforce on the right side of the vehicle 1000 is increased, thereby increasing the grip of the right side of the vehicle 1000 and preventing the vehicle 1000 from rolling over when turning left.

[0153] Please refer to Figure 8 , Figure 8 for Figure 2 The structure diagram of the vehicle 1000 shown is a schematic diagram of a single spoiler assembly 320 in a drag reduction state. In some embodiments, when the driving speed of the vehicle 1000 is less than the first preset speed and greater than the second preset speed, and the vehicle 1000 is accelerating, if the vehicle 1000 turns right and the deflection angle is less than the first preset angle, the spoiler assembly 320 on the left side of the first spoiler device 310A is controlled to switch to the spoiling state, and the spoiler assembly 320 on the right side of the first spoiler device 310A and the second spoiler device 310B are switched to the drag reduction state; if the vehicle 1000 turns left and the deflection angle is less than the first preset angle, the spoiler assembly 320 on the right side of the first spoiler device 310A is controlled to switch to the spoiling state, and the spoiler assembly 320 on the left side of the first spoiler device 310A and the second spoiler device 310B are switched to the drag reduction state.

[0154] When the vehicle 1000 is traveling at a relatively high speed and the driving angle is deflected, the vehicle 1000 is accelerated and the front end 110 is prone to tilting up, causing the vehicle 1000 to accelerate more slowly. Controlling the second spoiler 310B to switch to the resistance reduction state can reduce the grip of the rear section of the vehicle 1000 relative to the grip of the front section, so that the grip of the front section of the vehicle 1000 and the rear section of the vehicle 1000 are balanced, and the vehicle 1000 is not prone to tilting up.

[0155] If the vehicle 1000 turns right, the spoiler assembly 320 on the left side of the first spoiler device 310A is in the spoiling state, and the spoiler assembly 320 on the right side is in the drag reduction state, thereby increasing the grip on the left side of the vehicle 1000 and making it less likely for the vehicle 1000 to roll over when turning right. If the vehicle 1000 turns left, the spoiler assembly 320 on the left side of the first spoiler device 310A is in the drag reduction state, and the spoiler assembly 320 on the right side is in the spoiling state, thereby increasing the grip on the right side of the vehicle 1000 and making it less likely for the vehicle 1000 to roll over when turning left.

[0156] In some embodiments, when the vehicle 1000 is traveling at a speed less than a first preset speed and greater than a second preset speed, and is decelerating, if the vehicle 1000 turns right and the deflection angle is less than the first preset angle, the spoiler component 320 on the left side of the second spoiler device 310B is controlled to switch to a spoiling state, and the spoiler component 320 on the right side of the second spoiler device 310B and the first spoiler device 310A are switched to a drag reduction state; if the vehicle 1000 turns left and the deflection angle is less than the first preset angle, the spoiler component 320 on the right side of the second spoiler device 310B is controlled to switch to a spoiling state, and the spoiler component 320 on the left side of the second spoiler device 310B and the first spoiler device 310A are switched to a drag reduction state.

[0157] When the vehicle 1000 is traveling at a relatively high speed and the driving angle is deflected, the vehicle 1000 slows down and the rear end 120 is prone to tilt up, which lengthens the braking distance of the vehicle 1000. Controlling the first spoiler 310A to switch to the resistance reduction state can reduce the grip of the rear section of the vehicle 1000, balance the grip of the front section of the vehicle 1000 and the rear section of the vehicle 1000, and make it difficult for the rear end of the vehicle 1000 to tilt up and cause a tailspin, thereby shortening the braking distance.

[0158] If the vehicle 1000 turns right, the spoiler assembly 320 on the left side of the second spoiler device 310B is in the spoiling state, and the spoiler assembly 320 on the right side is in the drag reduction state, then the grip on the left side of the vehicle 1000 is increased, and the vehicle 1000 is less likely to roll when turning right. If the vehicle 1000 turns left, the spoiler assembly 320 on the left side of the second spoiler device 310B is in the drag reduction state, and the spoiler assembly 320 on the right side is in the spoiling state, then the grip on the right side of the vehicle 1000 is increased, and the vehicle 1000 is less likely to roll when turning left.

[0159] Please refer to Figure 2 In some embodiments, when the vehicle 1000 turns, the driving speed of the vehicle 1000 is less than the second preset speed, and the deflection angle is greater than the first preset angle, the plurality of spoiler components 320 are controlled to switch to the spoiler state.

[0160] When the yaw angle of vehicle 1000 is greater than the first preset angle, for safety reasons, the driving speed of vehicle 1000 is generally less than the second preset speed, and vehicle 1000 can then turn. For example, the yaw angle of vehicle 1000 is greater than or equal to 2° and less than or equal to 15°. For example, the yaw angle of vehicle 1000 is 3°, 5°, 9°, 12°, or 15°.

[0161] When the vehicle 1000 turns, the vehicle 1000 is prone to roll or drift. Therefore, controlling the multiple spoiler assemblies 320 to switch to the spoiler state can increase the downforce of the entire vehicle and ensure that the vehicle 1000 has sufficient grip, so that the vehicle 1000 can turn smoothly.

[0162] When the vehicle 1000 turns, the vehicle 1000 needs sufficient grip to ensure the cornering speed. At this time, the vehicle 1000 accelerates or decelerates, and the multiple spoiler components 320 maintain a spoiler state to ensure grip and prevent the vehicle 1000 from having an accident.

[0163] In some embodiments, the vehicle 1000 can manually control the vortex generator 300 , and the driver can manually control the driving device 340 to switch the state of the spoiler structure 330 according to the driving state.

[0164] In other embodiments, the vehicle 1000 may include an intelligent vehicle control system, which may include a speed detection device and an angle detection device, and automatically adjust the vortex generator 300 of the vehicle 1000 by identifying the speed and direction of the vehicle 1000 to put the vehicle 1000 in an optimal driving state.

[0165] In some embodiments, the vehicle 1000 may also include a front active diffuser, a rear active diffuser and an active air dam. The intelligent vehicle control system may simultaneously adjust the vortex generator 300, the front active diffuser, the rear active diffuser and the active air dam, thereby maximizing the aerodynamic efficiency of the vehicle 1000.

[0166] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0167] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
