[0069] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0070] According to the first aspect of the present application, refer to Figures 1 to 11 The present application provides a spoiler, comprising a shell 1, a first spoiler 2 and a second spoiler 3, the first spoiler 2 is arranged on the shell 1, the second spoiler 3 is connected to the shell 1 or the first spoiler 2, the first spoiler 2 and the second spoiler 3 can both move relative to the shell 1, and the movement directions of the first spoiler 2 and the second spoiler 3 are different.

[0071] It can be understood that the first spoiler 2 and the second spoiler 3 can both play a spoiler role. At the same time, since the first spoiler 2 and the second spoiler 3 move in different directions, when the first spoiler 2 and the second spoiler 3 play a spoiler role, the first spoiler 2 and the second spoiler 3 will move to different positions and play a spoiler role at different positions, thereby improving the overall spoiler effect of the spoiler, improving the performance of the spoiler, and helping to improve the stability of the vehicle equipped with the spoiler.

[0072] In some examples, the first spoiler 2 can move laterally, and the second spoiler 3 can move longitudinally.

[0073] In some examples, the first spoiler 2 can move laterally, and the second spoiler 3 can move rotationally.

[0074] In some examples, the first spoiler 2 may move in a horizontal direction, and the second spoiler 3 may move in a vertical direction.

[0075] In some embodiments, see Figure 1 and Figure 4 The spoiler also includes a driving component 4, which is installed on the shell 1 and connected to the first spoiler 2. The driving component 4 is used to drive the first spoiler 2 to extend and retract relative to the shell 1.

[0076] It is understandable that the driving assembly 4 can drive the first spoiler 2 to move, so that the first spoiler 2 can be extended relative to the housing 1, and the first spoiler 2 can be automatically moved. When the first spoiler 2 is needed to play a spoiling role, the driving assembly 4 drives the first spoiler 2 to extend relative to the housing 1, so that the first spoiler 2 can provide downward force; when the first spoiler 2 is not needed to play a spoiling role, the driving assembly 4 drives the first spoiler 2 to retract relative to the housing 1, which is conducive to reducing the wind resistance caused by the first spoiler 2.

[0077] It can be understood that when the first spoiler 2 is not needed to play a spoiler role, the first spoiler 2 can be retracted relative to the housing 1, which is beneficial to reducing wind resistance.

[0078] It can be understood that, compared with the rotatable arrangement of the first spoiler 2 , the telescopic arrangement of the first spoiler 2 occupies a smaller space, thereby reducing the degree of limitation on the arrangement position of the first spoiler 2 .

[0079] Specifically, the extension direction of the first spoiler 2 is the horizontal direction.

[0080] In some embodiments, see Figure 4 and Figure 6 The driving assembly 4 includes a first driving member 41 and a rolling member 42. The first spoiler 2 is connected to the rolling member 42. The rolling member 42 is connected to the first driving member 41. The first driving member 41 is used to drive the rolling member 42 to roll relative to the housing 1.

[0081] It can be understood that the first driving member 41 can drive the rolling member 42 to roll relative to the shell 1, so that the rolling member 42 can move relative to the shell 1, and the first spoiler 2 is connected to the rolling member 42, and then the first spoiler 2 will also move relative to the shell 1 with the rolling member 42, thereby realizing the motion control of the first spoiler 2.

[0082] In some examples, the first driving member 41 is, for example, a motor or a cylinder or any other suitable driving structure.

[0083] In some examples, the rolling element 42 is, for example, a roller or a gear or any other suitable rolling structure.

[0084] For details, see Figure 2 and Figure 3 The housing 1 is formed with a guide rail 11 , the rolling member 42 is connected to the guide rail 11 , and the rolling member 42 can move relative to the guide rail 11 .

[0085] It can be understood that the guide rail 11 can guide the movement of the rolling member 42, so that the rolling member 42 rolls along a specified direction, thereby ensuring that the first spoiler 2 can move along the specified direction.

[0086] For details, see Figure 4 and Figure 6 The spoiler also includes a connecting member 5, and the connecting member 5 connects the first spoiler 2 and the rolling member 42.

[0087] It can be understood that the first spoiler 2 and the rolling member 42 are connected by the connecting member 5 so that the first spoiler 2 can move along with the movement of the rolling member 42 .

[0088] In some examples, the connecting member 5 is, for example, a clamp or a connecting plate or any other suitable connecting structure.

[0089] In some embodiments, see Figure 1 and Figure 2 The housing 1 is formed with a receiving groove 12 for receiving the first spoiler 2 , and the first spoiler 2 can move relative to the receiving groove 12 .

[0090] It is understandable that by forming the receiving groove 12 in the housing 1, when the first spoiler 2 is not needed to play a spoiler role, the first spoiler 2 can be stored in the receiving groove 12, thereby achieving effective use of the space of the housing 1 and effectively reducing wind resistance.

[0091] In some embodiments, see Figure 1 and Figure 7 The spoiler further includes a second driving member 6 , which is mounted on the housing 1 or the first spoiler 2 , and is used to drive the second spoiler 3 to rotate.

[0092] It can be understood that the second spoiler 3 can be driven to rotate relative to the housing 1 by the second driving member 6, so that the second spoiler 3 can be switched between an open state and a closed state.

[0093] For details, see Figure 7 and Figure 8 The second driving member 6 includes a steering gear 61, and the steering gear 61 is connected to the second spoiler 3, and the steering gear 61 is used to drive the second spoiler 3 to rotate.

[0094] It can be understood that the second spoiler 3 is driven to rotate by the steering gear 61. When the second spoiler 3 rotates to a target angle, the steering gear 61 can control the second spoiler 3 to stop rotating and maintain the second spoiler 3 at the target angle.

[0095] In some embodiments, the spoiler also includes a pressure detection component 7 and a controller, the pressure detection component 7 is installed on the first spoiler 2 or the shell 1 or the second spoiler 3, the pressure detection component 7 is connected to the controller, the pressure detection component 7 is used to detect the airflow pressure, and the controller is configured to: control the operation of the second driving component 6 based on the detection data of the pressure detection component 7.

[0096] It can be understood that the pressure detection member 7 can be used to detect the airflow pressure at the spoiler, and the pressure detection member 7 can transmit the detection data to the controller, so that the controller can control the operation of the second driving member 6 according to the detection data of the pressure detection member 7, that is, the rotation of the second spoiler 3 can be controlled according to the airflow pressure at the spoiler, which is beneficial to improving the spoiler effect of the second spoiler 3.

[0097] According to the second aspect of this application, refer to Fig.12 The present application provides a spoiler assembly, including the above-mentioned spoiler.

[0098] It can be understood that the first spoiler 2 and the second spoiler 3 can both play a spoiler role. At the same time, since the first spoiler 2 and the second spoiler 3 move in different directions, when the first spoiler 2 and the second spoiler 3 play a spoiler role, the first spoiler 2 and the second spoiler 3 will move to different positions and play a spoiler role at different positions, thereby improving the overall spoiler effect of the spoiler, improving the performance of the spoiler, and then improving the performance of the entire spoiler assembly, which is beneficial to improving the stability of the vehicle equipped with the spoiler assembly.

[0099] In some embodiments, see Fig.12 , the spoiler assembly includes at least two spoilers.

[0100] It can be understood that by providing at least two spoilers, the first spoilers 2 of different spoilers are independent of each other and can be controlled individually, and the second spoilers 3 of different spoilers are also independent of each other and can be controlled individually, so that the spoiler assembly can have more combined spoiler effects to adapt to different usage environments.

[0101] It can be understood that the two spoilers can be adjusted independently to provide different downforces to the two sides of the vehicle, improve the vehicle's braking ability and enhance cornering stability.

[0102] In some embodiments, see Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11There are at least two first spoilers 2 of the spoilers arranged opposite to each other, wherein the first spoiler 2 of one of the spoilers is provided with a first clamping portion 21, and the first spoiler 2 of the other spoiler is provided with a second clamping portion, and the first clamping portion 21 can be clamped and matched with the second clamping portion.

[0103] It can be understood that the first spoilers 2 of the two spoilers are arranged relative to each other so that the first spoilers 2 of the two spoilers can move toward each other. When the first spoilers 2 of the two spoilers are fully opened, the first snap-fitting portion 21 and the second snap-fitting portion are snap-fitted to achieve the connection between the first spoilers 2 of the two spoilers, which is beneficial to improving the structural stability of the spoiler assembly.

[0104] According to the third aspect of this application, refer to Fig.13 The present application provides a vehicle shell, comprising the above-mentioned spoiler or spoiler assembly.

[0105] It can be understood that the first spoiler 2 and the second spoiler 3 can both play a spoiler role. At the same time, since the first spoiler 2 and the second spoiler 3 have different movement directions, when the first spoiler 2 and the second spoiler 3 play a spoiler role, the first spoiler 2 and the second spoiler 3 will move to different positions and play a spoiler role at different positions, thereby improving the overall spoiler effect of the spoiler, improving the performance of the spoiler, and then improving the performance of the entire spoiler assembly, so that the performance of the vehicle shell can also be improved.

[0106] In some embodiments, see Fig.13 The vehicle shell includes a shell body 8, and the shell 1 is fixedly connected to the shell body 8.

[0107] It can be understood that the shell 1 of the spoiler is fixedly connected to the shell body 8 to fix the shell 1, so that the first spoiler 2 and the second spoiler 3 can move relative to the shell 1, and the first spoiler 2 and the second spoiler 3 can move relative to the vehicle shell.

[0108] According to a fourth aspect of the present application, the present application provides a vehicle, comprising the above-mentioned spoiler or spoiler assembly or vehicle shell.

[0109] It can be understood that the first spoiler 2 and the second spoiler 3 can both play a spoiler role. At the same time, since the first spoiler 2 and the second spoiler 3 have different movement directions, when the first spoiler 2 and the second spoiler 3 play a spoiler role, the first spoiler 2 and the second spoiler 3 will move to different positions and play a spoiler role at different positions, thereby improving the overall spoiler effect of the spoiler, improving the performance of the spoiler, improving the performance of the entire spoiler assembly, and thereby improving the performance of the vehicle.

[0110] In some examples, the vehicle may be a fuel vehicle, a plug-in hybrid vehicle, or a new energy vehicle, etc., and this application does not make specific limitations on this.

[0111] According to the fifth aspect of the present application, refer to Fig.14 The present application provides a spoiler control method, which is applied to a vehicle; the spoiler comprises a housing 1 and a first spoiler 2, the first spoiler 2 is arranged on the housing 1, and the first spoiler 2 can move relative to the housing 1; the spoiler control method comprises:

[0112] Step 100: Control the movement of the first spoiler 2 according to the mode information of the vehicle.

[0113] It is understandable that the vehicle has different requirements for wind resistance and downforce in different modes. The present application determines the current mode of the vehicle according to the mode information of the vehicle, and then determines the requirements of the vehicle for wind resistance and downforce according to the current mode of the vehicle, and then controls the movement of the first spoiler 2 so that the wind resistance and downforce brought by the first spoiler 2 can meet the requirements of the current mode of the vehicle, thereby realizing automatic regulation of the first spoiler 2 according to the requirements, reducing the amount of operation of the driver, and being conducive to improving the control accuracy and the degree of intelligence.

[0114] That is, the present application realizes automatic allocation of wind resistance and downforce for the vehicle according to the driving status when the vehicle is driving, intelligently adapting to more complex aerodynamic conditions, and meeting the user's richer driving needs.

[0115] In some embodiments, the step of controlling the movement of the first spoiler 2 according to the mode information of the vehicle comprises:

[0116] Determining, according to the mode information of the vehicle, whether the vehicle is in a sports mode or a comfort mode;

[0117] The first spoiler 2 is controlled to be fully opened.

[0118] It can be understood that when it is determined that the vehicle is in the sport mode or the comfort mode based on the vehicle mode information, it means that the driving state of the vehicle at this time is a high control demand, that is, the user may have a high control demand at this time, and then control the first spoiler 2 to be fully opened, so that the first spoiler 2 can provide downforce for the vehicle and improve the stability of the vehicle.

[0119] In some examples, when the first spoiler 2 is controlled to be fully opened, the opening information of the first spoiler 2 can be obtained, and then it is determined whether the opening of the first spoiler 2 is less than the preset opening; if it is less than, it means that the first spoiler 2 is not fully opened at this time, and then the first spoiler 2 is controlled to continue to open; if it is not less than, it means that the first spoiler 2 is already fully opened at this time, and the movement control of the first spoiler 2 is stopped, and then it can be determined whether the second spoiler 3 needs to be opened according to the driving conditions.

[0120] In some embodiments, the spoiler further includes a second spoiler 3, and the second spoiler 3 is rotatably connected to the housing 1; after the step of controlling the first spoiler 2 to be fully opened, the method further includes:

[0121] Based on the driving speed of the vehicle, the rotation of the second spoiler 3 is controlled.

[0122] It is understandable that after the first spoiler 2 is controlled to be fully opened, the rotation of the second spoiler 3 can be controlled according to the driving speed of the vehicle, so that the second spoiler 3 can cooperate with the first spoiler 2 to improve the driving performance of the vehicle.

[0123] Specifically, the step of controlling the rotation of the second spoiler 3 based on the driving speed of the vehicle includes:

[0124] When the running speed of the vehicle is greater than or equal to a preset speed, the second spoiler 3 is controlled to open; or,

[0125] When the running speed of the vehicle is less than a preset speed, the second spoiler 3 is controlled to be completely closed.

[0126] It can be understood that when the rotation of the second spoiler 3 is controlled based on the driving speed of the vehicle, it is first determined whether the driving speed of the vehicle is greater than or equal to the preset speed. If it is greater than, it means that the driving speed of the vehicle is faster, and the stability of the vehicle needs to be improved at this time. Therefore, the second spoiler 3 is controlled to be opened so that the second spoiler 3 can provide downforce to the vehicle to improve the driving stability of the vehicle. If it is less than, it means that the downforce provided by the first spoiler 2 to the vehicle at this time is enough to keep the vehicle stable. Therefore, the second spoiler 3 is controlled to be completely closed to prevent the second spoiler 3 from increasing the wind resistance of the vehicle.

[0127] In some examples, the second spoiler 3 is connected to the steering gear 61, and the steering gear 61 is used to drive the second spoiler 3 to rotate. When controlling the second spoiler 3 to be fully opened or fully closed, the current rotation angle of the steering gear 61 can be obtained, and the current rotation angle of the steering gear 61 can be compared with the target rotation angle, so as to determine whether the second spoiler 3 is fully opened or fully closed.

[0128] Exemplarily, when the second spoiler 3 is controlled to be fully opened, when the current rotation angle of the steering gear 61 is less than 90°, it means that the second spoiler 3 is not fully opened at this time, and then the second spoiler 3 can be controlled to continue to rotate so that the second spoiler 3 is fully opened.

[0129] Exemplarily, when the second spoiler 3 is controlled to be completely closed, when the current rotation angle of the steering gear 61 is greater than 0°, it means that the second spoiler 3 is not completely closed at this time, and then the second spoiler 3 can be controlled to continue to rotate to make the second spoiler 3 completely closed.

[0130] In some embodiments, the step of controlling the movement of the first spoiler 2 according to the mode information of the vehicle comprises:

[0131] Determining, based on the mode information of the vehicle, that the vehicle is in an economy mode;

[0132] The first spoiler 2 is controlled to be completely closed.

[0133] It can be understood that when it is determined that the vehicle is in economy mode based on the vehicle mode information, it means that the driving state of the vehicle at this time has a high endurance requirement, that is, the user has a high endurance requirement at this time, and then controls the first spoiler 2 to be completely closed to reduce the wind resistance brought by the first spoiler 2, reduce the wind resistance of the vehicle, and improve the vehicle's endurance.

[0134] In some examples, when controlling the first spoiler 2 to be completely closed, the opening information of the first spoiler 2 can be obtained, and then it is determined whether the opening of the first spoiler 2 is greater than the target opening value; if it is greater than, it means that the first spoiler 2 is not completely closed at this time, and then the first spoiler 2 is controlled to continue closing; if it is not greater than, it means that the first spoiler 2 is completely closed at this time, and the movement control of the first spoiler 2 is stopped.

[0135] In some embodiments, the spoiler further includes a second spoiler 3, and the second spoiler 3 is rotatably connected to the housing 1; the spoiler control method further includes:

[0136] Based on the braking information of the vehicle, the rotation of the second spoiler 3 is controlled.

[0137] It can be understood that, according to the braking information of the vehicle, the current braking state of the vehicle can be determined, and then the rotation of the second spoiler 3 can be controlled according to the braking state of the vehicle.

[0138] When it is determined according to the vehicle's braking information that the vehicle is in an emergency braking state, the vehicle needs downforce to increase stability, so the second spoiler 3 can be controlled to open so that the second spoiler 3 can provide downforce to the vehicle to improve the stability and safety of the vehicle.

[0139] When it is determined according to the braking information of the vehicle that the vehicle is not in an emergency braking state, it is possible to further combine the vehicle speed, turning angle and other information to comprehensively determine how to control the second spoiler 3 .

[0140] Specifically, the step of controlling the rotation of the second spoiler 3 based on the braking information of the vehicle includes:

[0141] When the braking depth of the vehicle is greater than or equal to a preset depth, the second spoiler 3 is controlled to be fully opened.

[0142] It is understandable that whether the vehicle is in an emergency braking state can be determined according to the braking depth of the vehicle. When the braking depth of the vehicle is greater than or equal to the preset depth, it means that the vehicle is in an emergency braking state at this time, so the second spoiler 3 can be controlled to be fully opened to provide downforce and wind resistance for the vehicle.

[0143] In some embodiments, the spoiler further includes a second spoiler 3, and the second spoiler 3 is rotatably connected to the housing 1; the spoiler control method further includes:

[0144] Based on the turning angle of the vehicle, the rotation of the second spoiler 3 is controlled.

[0145] It is understandable that, according to the turning angle of the vehicle, it can be determined whether the vehicle is currently in a sharp turn state, and then the rotation of the second spoiler 3 is controlled according to the determination result, so that the second spoiler 3 can adapt to the real-time state of the vehicle.

[0146] Specifically, the number of the second spoilers 3 is at least two, and the two second spoilers 3 are respectively located on both sides of the vehicle; the step of controlling the rotation of the second spoiler 3 based on the turning angle of the vehicle includes:

[0147] When the turning angle of the vehicle is not less than a preset angle, one of the second spoilers 3 is controlled to rotate 0°, and the other second spoiler 3 is controlled to rotate 90°.

[0148] It is understandable that when the rotation of the second spoiler 3 is controlled based on the turning angle of the vehicle, the turning angle of the vehicle is compared with the preset angle. When the turning angle of the vehicle is not less than the preset angle, it indicates that the vehicle is in a sharp turn state.

[0149] The two second spoilers 3 are respectively located on both sides of the vehicle, that is, one of the second spoilers 3 is located on the left side of the vehicle, and the other second spoiler 3 is located on the right side of the vehicle. Exemplarily, when the vehicle turns sharply to the right, the second spoiler 3 on the right side is controlled to rotate 90°, so that the second spoiler 3 on the right side is fully opened, providing downforce for the right side of the vehicle, and improving the stability of the vehicle when turning, while the second spoiler 3 on the left side is rotated 0°, that is, the second spoiler 3 on the left side is not opened.

[0150] In some examples, the steering wheel angle α is obtained; it is determined whether |α| is greater than or equal to the steering threshold α0; if so, the driving condition is determined to be a sharp turn; the corresponding angles θ1=45+(45α / |α|) and θ2=45-(45α / |α|) are output, and θ1 and θ2 correspond to the rotation angles of the second spoiler 3 on the left and right sides, respectively.

[0151] Preferably, in order to effectively adjust the driving resistance and downforce distribution, the turning angles θ1 and θ2 are as follows:

[0152]

[0153] θ1∈[0°,90°] (1)

[0154] ,θ2∈[0°,90°] (2)

[0155] Wherein, P0 is 1 standard atmospheric pressure, P1 and P2 are the pressure measurements on the first spoiler 2 on the left and the first spoiler 2 on the right, respectively, in units of pa;

[0156] The control strategy of the present invention is based on detecting the incoming flow pressure on the first spoiler 2, calculating the pressure difference between the left and right spoilers, and determining the optimal second spoiler 3 angle by the ratio of the pressure difference to the empirical pressure under simulation and test conditions, that is, the output angle θ = standard angle θ a +Difference angle θ b , where the output angle θ refers to the angle control signals θ1 and θ2 output to the second spoiler 3, and the standard angle θ a Refers to the spoiler angle corresponding to the air resistance required when the vehicle decelerates through a corner, which is obtained by taking the difference between P0 and P1 and the ratio of the empirical value; the difference angle θ b Refers to the turning angle of the second spoiler 3 required for assisting cornering, calculated based on the pressure difference between the left and right second spoilers 3, obtained by subtracting the measured point values ​​P1 and P2 and then comparing them with the empirical value (the empirical value is between 180Pa and 1200Pa, preferably 260Pa). This changes the force on the second spoiler 3 and the side and rear of the vehicle body, so that the whole vehicle obtains downforce with the point of action on the same side as the turning direction when driving at high speed, thereby improving the driving stability of the whole vehicle.

[0157] Specifically, the step of controlling the rotation of the second spoiler 3 based on the turning angle of the vehicle includes:

[0158] When the turning angle of the vehicle is less than a preset angle, obtaining the airflow pressure at the spoiler;

[0159] determining a target rotation angle of the second spoiler 3 based on the airflow pressure;

[0160] Based on the target rotation angle, the rotation of the second spoiler 3 is controlled.

[0161] It is understandable that when the rotation of the second spoiler 3 is controlled based on the turning angle of the vehicle, the turning angle of the vehicle is compared with the preset angle. When the turning angle of the vehicle is less than the preset angle, it indicates that the vehicle is not in a sharp turn state.

[0162] At this time, the target rotation angle of the second spoiler 3 can be determined according to the airflow pressure at the spoiler, and then the rotation of the second spoiler 3 is controlled according to the target rotation angle, so that the rotation angle of the second spoiler 3 is adapted to the airflow pressure, which is beneficial to improving the driving performance of the vehicle.

[0163] In some examples, the steering engine 61 is used to drive the rotation of the second spoiler 3. When controlling the rotation of the second spoiler 3:

[0164] Obtaining the current rotation angle of the second spoiler 3;

[0165] Determine whether the current rotation angle of the second spoiler 3 is greater than θ1 (θ2 for the right second spoiler 3);

[0166] When the current turning angle of the second spoiler 3 is greater than the control turning angle θ1, it is determined that the turning angle of the second spoiler 3 is too large;

[0167] A reverse signal is sent to the steering engine 61 to control the second spoiler 3 to reduce the turning angle;

[0168] Determine whether the current rotation angle of the second spoiler 3 is less than θ1 (θ2 for the right second spoiler 3);

[0169] When the current turning angle of the second spoiler 3 is less than the control turning angle θ1, it is determined that the turning angle of the second spoiler 3 is too small;

[0170] Send a forward rotation signal to the steering engine 61 to control the second spoiler 3 to increase the rotation angle;

[0171] When the current rotation angle of the second spoiler 3 is equal to the control rotation angle θ1, it is determined that the rotation angle of the second spoiler 3 reaches the control value;

[0172] A stop signal is sent to the steering engine 61 to control the second spoiler 3 to limit its position.
