[0066] This application provides a tail wing device, which can be used in vehicles in practical applications. The tail wing device of this application will be described in detail below with reference to the accompanying drawings.

[0067] Reference Figures 1-6 Specifically, the tail wing device described in this application embodiment includes: a tail wing body 1; a hydraulic mechanism 3 and a pressure holding valve disposed on the hydraulic mechanism 3, the hydraulic mechanism 3 being used to drive the tail wing body 1 to open or close; and a pressure holding valve disposed on the hydraulic mechanism 3 to maintain the liquid pressure in the hydraulic mechanism 3.

[0068] Specifically, the rear wing body 1 can be opened or closed to adjust the direction and intensity of airflow, thereby optimizing aerodynamic performance. For example, when the vehicle is traveling at high speed on a straight road, the rear wing body 1 can be opened to reduce air resistance and increase vehicle speed. When the vehicle is traveling at high speed on a curve, the rear wing body 1 can be closed to provide downforce during cornering and improve the vehicle's high-speed cornering ability. The hydraulic mechanism 3 provides liquid pressure, which can be hydraulic oil or other types of brake fluid. The liquid pressure drives the opening and closing of the rear wing body 1. A pressure-holding valve is located in the hydraulic mechanism 3. When the hydraulic mechanism 3 increases the liquid pressure to drive the rear wing body 1 to open, the pressure-holding valve maintains the liquid pressure in the hydraulic mechanism 3 at a high pressure.

[0069] In this embodiment, by setting a pressure-holding valve (not shown in the figure) in the hydraulic mechanism 3, after the hydraulic mechanism 3 increases the liquid pressure to drive the tail wing body 1 to open, the pressure-holding valve can keep the high-pressure liquid in a high-pressure state. When the tail wing body 1 needs to be opened again, since the liquid is already in a high-pressure state, the hydraulic mechanism 3 can quickly provide sufficient pressure, reduce the pressure build-up time, improve the response speed of the tail wing device, and thus improve the safety and stability of the vehicle.

[0070] In some embodiments, the hydraulic mechanism 3 includes: a first hydraulic pipe 310, the second end of which is connected to the tail fin body 1 in a transmission manner, the first hydraulic pipe 310 being used to transmit oil to drive the tail fin body 1 to open or close; and a pressure holding valve disposed at the first end of the first hydraulic pipe 310 for blocking at least a portion of the first hydraulic pipe 310 to maintain the liquid pressure of the first hydraulic pipe 310.

[0071] like Figures 1-4 As shown, the first hydraulic pipe 310 has a first end and a second end. The first end can be connected to a hydraulic source or other hydraulic components, and the second end can be connected to the tail fin body 1 for transmission. The first hydraulic pipe 310 can transmit high-pressure oil from the hydraulic source or other hydraulic components to the tail fin body 1, thereby driving the tail fin body 1 to open or close through the driving force generated by the high-pressure oil. The first hydraulic pipe 310 is made of pressure-resistant material so that it can withstand the transportation of high-pressure liquid.

[0072] A pressure-holding valve is located at the first end of the first hydraulic pipeline 310. It can maintain the liquid pressure in the first hydraulic pipeline 310 by partially blocking it, ensuring that the hydraulic mechanism 3 can quickly provide sufficient pressure when needed. Specifically, the pressure-holding valve has an internal valve. When the pressure in the first hydraulic pipeline 310 exceeds a set upper limit pressure, the internal valve closes, partially blocking the first hydraulic pipeline 310, preventing liquid backflow and maintaining pressure. If the liquid pressure drops below a set lower limit, the internal valve opens, allowing the first hydraulic pipeline 310 to reconnect and replenish liquid until the set upper pressure value is reached.

[0073] In this embodiment, by providing a pressure-holding valve at the first end of the first hydraulic pipe 310, a portion of the pipe can be effectively blocked to prevent oil backflow and ensure that the liquid pressure within the first hydraulic pipe 310 remains at a set value. This allows the hydraulic mechanism 3 to quickly provide sufficient pressure when the tail fin body 1 needs to be reopened, reducing pressure build-up time and improving the response speed of the tail fin device.

[0074] like Figure 1-4As shown, optionally, the hydraulic mechanism 3 includes a hydraulic pump 30, which is connected to the first end of the first hydraulic pipeline 310; the pressure holding valve is disposed in the passage between the hydraulic pump 30 and the first hydraulic pipeline 310, and the pressure holding valve maintains the liquid pressure by controlling the opening of the passage between the hydraulic pump 30 and the first hydraulic pipeline 310.

[0075] Specifically, the hydraulic pump 30 generates high-pressure liquid through internal mechanical movement. Furthermore, the hydraulic pump 30 can be any of a rotor pump, gear pump, or vane pump. The first end of the first hydraulic pipe 310 is connected to the outlet of the hydraulic pump, which can transmit the high-pressure liquid in the hydraulic pump 30 to the tail fin body 1, thereby enabling the tail fin body 1 to open or close.

[0076] A pressure-holding valve is installed in the passage between the hydraulic pump 30 and the hydraulic pipeline 31 to control the liquid pressure in the hydraulic mechanism 3, ensuring that the system can quickly provide sufficient pressure when needed. The pressure-holding valve maintains liquid pressure by controlling the opening of the passage between the hydraulic pump 30 and the first hydraulic pipeline 310. Specifically, the pressure-holding valve has an internal valve. When the pressure in the first hydraulic pipeline 310 exceeds the set upper limit pressure, the internal valve of the pressure-holding valve closes, making the opening of the passage between the hydraulic pump 30 and the first hydraulic pipeline 310 zero, preventing liquid backflow and maintaining pressure. If the liquid pressure drops and falls below the set lower limit, the internal valve of the pressure-holding valve opens, allowing the passage between the hydraulic pump 30 and the first hydraulic pipeline 310 to have a certain opening to replenish liquid until the set upper pressure value is reached.

[0077] In this embodiment, by setting a pressure-holding valve in the passage between the hydraulic pump 30 and the first hydraulic pipe 310, the hydraulic pressure in the first hydraulic pipe 310 can always be kept in a high-pressure state. When the tail wing body 1 needs to be opened again, the hydraulic mechanism 3 can quickly provide sufficient pressure, reduce the pressure build-up time, and further improve the response speed of the tail wing device.

[0078] In some alternative embodiments, the pressure-holding valve is located at the liquid outlet of the hydraulic pump 30.

[0079] Specifically, a pressure-holding valve is integrated into the hydraulic pump 30. Located between the liquid outlet of the hydraulic pump 30 and the hydraulic pipeline 31, the pressure-holding valve directly maintains the liquid pressure by controlling the opening of the liquid outlet of the hydraulic pump 30. Specifically, when the pressure in the first hydraulic pipeline 310 exceeds a set upper limit pressure, the pressure-holding valve closes, making the opening of the liquid outlet of the hydraulic pump 30 zero. When the pressure falls below a set lower limit, the pressure-holding valve opens, giving the liquid outlet of the hydraulic pump 30 a certain opening. In this way, the pressure-holding valve can maintain the pressure in the hydraulic mechanism 3 more quickly. When the hydraulic mechanism 3 needs to maintain high pressure, the pressure-holding valve can quickly close to prevent pressure drop, improving the response speed of the hydraulic mechanism 3 and further improving the response speed of the tail fin device. Furthermore, since the pressure-holding valve is integrated into the hydraulic pump 30, the size of the hydraulic mechanism 3 can be reduced, simplifying the installation process.

[0080] In some alternative embodiments, the pressure holding valve is disposed on the first hydraulic conduit 310.

[0081] Specifically, the pressure-holding valve can be installed on a section of the first hydraulic pipe 310, and can be fixed to the first hydraulic pipe 310 by means of threaded connection, flange connection, or other fixing methods. It maintains the liquid pressure by controlling the opening of the first hydraulic pipe 310. When the internal pressure of the first hydraulic pipe 310 reaches the set pressure, the pressure-holding valve closes, the opening of the first hydraulic pipe 310 becomes 0, blocking the first hydraulic pipe 310 and preventing the backflow of high-pressure liquid. This ensures that the pressure inside the first hydraulic pipe 310 is maintained at the set value, ensuring that the tail fin body 1 can respond quickly when needed. In practical applications, by installing the pressure-holding valve on a section of the first hydraulic pipe 310, the valve can be placed closer to the location where pressure needs to be maintained. When pressure needs to be re-established, the pressure-holding valve can open quickly, allowing the high-pressure oil to reach the target position rapidly, improving the response speed of the tail fin device.

[0082] In some alternative embodiments, the hydraulic mechanism 3 further includes a hydraulic cylinder 32, which is connected between the second end of the first hydraulic pipe 310 and the tail fin body 1; the hydraulic pump 30 inputs the liquid into the hydraulic cylinder 32 through the first hydraulic pipe 310, and the hydraulic cylinder 32 drives the tail fin body 1 to open or close under the action of liquid pressure.

[0083] Specifically, the first end of the first hydraulic pipe 310 is connected to the hydraulic pump 30, and the second end of the first hydraulic pipe 310 is connected between the hydraulic cylinder 32 and the tail fin body 1. High-pressure hydraulic fluid in the hydraulic pump 30 is transmitted to the hydraulic cylinder 32 through the first hydraulic pipe 310. The hydraulic cylinder 32 contains a piston and a piston rod connected to the piston. The piston rod can extend out of the hydraulic cylinder 32 and connect to the tail fin body 1. Under the action of the high-pressure fluid, the piston moves within the hydraulic cylinder 32, driving the piston rod to move, thereby opening or closing the tail fin body 1. For example, when the fluid pressure increases, the piston rod extends outward, and the tail fin body 1 opens; when the fluid pressure decreases, the piston rod retracts inward, and the tail fin body 1 closes. In this embodiment, by coordinating the hydraulic pump 30 and the hydraulic cylinder 32, the fluid pressure can be quickly transmitted to the tail fin body 1, improving the response speed of the tail fin body 1.

[0084] In some alternative embodiments, a check valve and a throttle valve may also be provided on the hydraulic cylinder 32 to control the flow rate of the return fluid.

[0085] In some alternative embodiments, the hydraulic mechanism 3 further includes a drive member 33 connected to the hydraulic pump 30, the drive member 33 being used to drive the hydraulic pump 30 to work.

[0086] Specifically, the drive component 33 can be a drive motor, etc., and can be connected to an external power supply device. The external power supply device provides current to the drive component 33, enabling it to operate. The output terminal 35 of the drive component 33 is connected to the hydraulic pump 30. When the drive component 33 operates, it drives the hydraulic pump 30 to generate high-pressure liquid. In practical applications, by setting up the drive component 33, it can quickly start the hydraulic pump 30 according to the control signal, allowing the hydraulic mechanism 3 to quickly respond to the control signal to open or close the tail fin body 1, thereby improving the response speed of the tail fin device.

[0087] Furthermore, a controller (not shown in the figure) can be integrated on the drive unit 33. This controller can connect to the vehicle's control system via the Controller Area Network (CAN) protocol. The controller receives control signals sent by the vehicle control system and controls the drive unit 33 to operate according to the control signals. In practical applications, the integrated design of the controller and drive unit 33 further simplifies the structure of the hydraulic mechanism 3 and improves its reliability and stability.

[0088] In some embodiments, such as Figures 1-4As shown, the hydraulic mechanism 3 further includes: a second hydraulic pipe 311, the first end of which is connected to the hydraulic cylinder 32, and the second end of which is connected to the hydraulic pump 30; the second hydraulic pipe 311 is used to transfer the liquid in the hydraulic cylinder 32 to the hydraulic pump 30.

[0089] Specifically, the first hydraulic pipe 310 is connected between the outlet of the hydraulic pump 30 and the inlet of the hydraulic cylinder 32. The first hydraulic pipe 310 can transmit the high-pressure liquid in the hydraulic pump 30 to the hydraulic cylinder 32. The second hydraulic pipe 311 is connected between the outlet of the hydraulic cylinder 32 and the inlet of the hydraulic pump 30, and can then transmit the liquid in the hydraulic cylinder 32 to the hydraulic pump 30. In this way, by setting the first hydraulic pipe 310 and the second hydraulic pipe 311, the liquid in the hydraulic mechanism 3 can be recycled, reducing the amount of oil consumed, lowering the operating cost, and the recycled oil can reach the hydraulic cylinder 32 more quickly, improving the response speed of the hydraulic mechanism 3.

[0090] In some alternative embodiments, the tail fin device further includes a transmission mechanism 2, which is disposed between the tail fin body 1 and the hydraulic mechanism 3. The transmission mechanism 2 is driven by the hydraulic mechanism 3 to drive the tail fin body 1 to open or close.

[0091] like Figures 1-4 As shown, the transmission mechanism 2 can convert the liquid pressure provided by the hydraulic mechanism 3 into mechanical motion. The transmission mechanism 2 can be implemented by means of linkage transmission, gear transmission, etc., to convert the motion of the hydraulic mechanism 3 into a more complex motion form, such as rotational motion or compound motion. In practical applications, by setting the transmission mechanism 2, the driving force provided by the hydraulic mechanism 3 can be utilized more effectively to improve the opening and closing speed of the tail fin body, thereby improving the response speed of the entire tail fin device.

[0092] like Figure 5 and Figure 6 As shown, the transmission mechanism 2 includes: a first connecting rod 21, the first end of the first connecting rod 21 being connected to the output end of the hydraulic mechanism 3, and the second end of the first connecting rod 21 being movably connected to the tail fin body 1. The output end 35 of the hydraulic mechanism 3 can drive the first connecting rod 21 to move, so as to open or close the tail fin body 1.

[0093] Specifically, the first connecting rod 21 can be a rigid structural component with a first end and a second end. The first end is connected to the output end 35 of the hydraulic cylinder 32 in the hydraulic mechanism 3, and the second end is connected to the tail fin body 1. Movement of the output end 35 of the hydraulic mechanism 3 drives the first connecting rod 21 to move. The second end of the first connecting rod 21 can be connected to the tail fin body 1 by means of rotational connection, hinge connection, or other methods. Thus, the tail fin body 1 can be moved via the first connecting rod 21, thereby opening or closing the tail fin body 1. In practical applications, the opening or closing of the tail fin body 1 can be achieved simply by setting the first connecting rod 21, making the structure of the transmission mechanism 2 relatively simple, reducing the number and complexity of parts, and lowering the cost of the tail fin device.

[0094] Furthermore, the transmission mechanism 2 also includes a second link 22, the first end of which is movably connected to the tail fin body 1, and the second end of which is movably connected to the second end of the first link 21. The hydraulic mechanism 3 can drive the tail fin body 1 to move through the first link 21 and the second link 22.

[0095] like Figure 5 and Figure 6 As shown, the second link 22 is also a rigid structural component, having a first end and a second end. The first end is connected to the tail fin body 1 via a rotatable connection, hinge connection, or other movable connection. The second end is movably connected to the second end of the first link 21 via a rotatable connection, hinge connection, or other movable connection. When the output end 35 in the hydraulic mechanism 3 moves, driving the first link 21 to move, the first link 21 drives the second link 22 to move, thereby causing the tail fin body 1 to move and opening or closing. In this embodiment, multi-stage transmission is achieved through the cooperation of the first link 21 and the second link 22, which allows for more precise control of the movement of the tail fin body 1 and rapid transmission of the output power of the hydraulic cylinder 32, enabling the tail fin body 1 to respond quickly to control signals.

[0096] Furthermore, the transmission mechanism also includes a third link 23, the first end of which is movably connected to the second end of the first link 21, and the second end of which is movably connected to the second end of the second link 22. The hydraulic mechanism drives the tail fin body 1 to move through the first link 21, the third link 23 and the second link 22.

[0097] like Figures 5-6As shown, specifically, the third link 23 is also a rigid structural component, having a first end and a second end. The first end is movably connected to the second end of the first link 21 via a rotational connection, hinge connection, or other means. The second end is movably connected to the second end of the second link 22 via a rotational connection, hinge connection, or other means. When the output end 35 of the hydraulic mechanism 3 moves, driving the first link 21 to move, the first link 21 drives the second link 22 and the third link 23 to move, thereby driving the tail fin body 1 to move, realizing the opening or closing of the tail fin body 1. In this embodiment, the first link 21, the second link 22, and the third link 23 together form a multi-stage transmission mechanism 2, enabling the hydraulic mechanism 3 to more precisely control the opening and closing actions of the tail fin body 1. The movement of the hydraulic mechanism 3 can be converted into the movement of the tail fin body 1 through the three links, ensuring effective power transmission.

[0098] In some optional embodiments, the third link 23 further includes: a link body 231; a drive cantilever 230, the first end of which is fixedly connected to the first end of the link body 231, and the second end of which is movably connected to the second end of the first link 21; and an execution cantilever 232, the first end of which is fixedly connected to the second end of the link body 231, and the second end of which is movably connected to the second end of the second link 22.

[0099] Specifically, the connecting rod body 231, the drive cantilever 230, and the actuating cantilever 232 can be integrally formed components, ensuring the rigidity and strength of the third connecting rod 23. The drive cantilever 230 is movably connected to the second end of the first connecting rod 21 via a rotatable connection, hinge connection, or other means. Similarly, the actuating cantilever 232 is movably connected to the second end of the second connecting rod 22 via a rotatable connection, hinge connection, or other means. Movement of the first connecting rod 21 moves the drive cantilever 230, which in turn moves the connecting rod body 231 and the actuating cantilever 232. Furthermore, the length of the drive cantilever 230 is shorter than that of the actuating cantilever 232. In practical applications, by making the length of the drive cantilever 230 shorter than that of the actuating cantilever 232, the stroke of the third connecting rod 23 can be shortened, thereby shortening the stroke of the output end 35 of the hydraulic mechanism 3. This reduces the fluid demand, decreases the volume and weight of the hydraulic mechanism 3, and improves the response speed of the hydraulic mechanism 3.

[0100] Optionally, the tail fin body 1 includes a main wing 11 and a flap 13. The flap 13 is rotatably connected to the main wing 11, and the second end of the first connecting rod 21 is movably connected to the flap 13. The hydraulic mechanism 3 can drive the first connecting rod 21 to move linearly, so as to drive the flap 13 to rotate relative to the main wing 11.

[0101] Specifically, such as Figures 1-6 As shown, the main wing 11 and flap 13 are arranged side by side, and the flap 13 can be rotatably connected to the main wing 11, that is, the flap 13 can rotate relative to the main wing 11, as shown. Figure 1 The diagram shows the rear wing in its closed state. In this state, when the vehicle is traveling at high speed through a curve, the rear wing provides downforce during cornering, improving the vehicle's high-speed cornering ability. When the flap 13 rotates counterclockwise relative to the main wing 11 by a certain angle, the rear wing is in its open state. In this state, when the vehicle is traveling at high speed on a straight road, the rear wing reduces air resistance, increasing the vehicle's speed. The transition from the closed state to the open state is defined as the opening process, and the transition from the open state to the closed state is defined as the closing process. The rotation angle can be adjusted according to actual needs, improving the flexibility of the rear wing.

[0102] In the hydraulic mechanism 3, the piston inside the hydraulic cylinder 32 moves linearly, driving the output end 35 of the piston rod to move linearly, which in turn drives the first connecting rod 21 to move linearly. The second end of the first connecting rod 21 can be movably connected to the flap 13 by means of rotational connection, hinge connection, etc. The linear movement of the first connecting rod 21 drives the flap 13 to rotate relative to the main wing 11. In practical applications, by setting the first connecting rod 21 between the output end 35 of the hydraulic cylinder 32 and the tail wing body 1, the mechanical movement jamming caused by the direct connection between the output end 35 and the first connecting rod 21 can be avoided, making the movement of the transmission mechanism 2 more stable and smooth, and thus making the movement of the tail wing body 1 smoother.

[0103] Optionally, the first connecting rod 21 is set at an angle to the rotation axis of the flap 13.

[0104] Specifically, the rotation axes of the first link 21 and the flap 13 are set at an angle, which can be 90°. This creates a force-saving lever mechanism between the first link 21, the flap 13, and the rotation axis 14. This means that during opening, the applied torque of the air pressure is in the same direction as the torque applied by the first link 21, providing an assist effect. A smaller input force can generate a larger output force, reducing the power required by the hydraulic mechanism 3 and improving its energy efficiency. Furthermore, during opening, the response speed of the flap 13 is improved, further enhancing the response speed of the tail fin device.

[0105] Optionally, the tail fin body 1 includes a main wing 11 and a flap 13, the flap 13 being rotatably connected to the main wing 11; the first end of the second link 22 is rotatably connected to the flap 13, and the hydraulic mechanism 3 can drive the first link 21 to move linearly, thereby driving the second link 22 to rotate, so as to drive the flap 13 to rotate relative to the main wing 11.

[0106] Specifically, the flap 13 can rotate relative to the main wing 11, so that the tail assembly is in a position such that... Figure 1 The diagram shows the tail fin assembly in its closed state and the flap 13 in its open state when rotated counterclockwise relative to the main wing 11 by a certain angle. A mounting base can be installed on the flap 13. The first end of the second link 22 can be rotatably connected to the mounting base via a shaft. The second end of the second link 22 is rotatably connected to the second end of the first link 21 via a rotatable connection and a hinge connection. The output end 35 of the hydraulic mechanism 3 moves linearly, causing the first link 21 to move linearly. The first link 21 drives the second link 22 to rotate, causing the flap 13 to rotate relative to the main wing 11, thus placing the tail fin body 1 in either a closed or open state. In practical applications, by setting the second link 22 between the first link 21 and the flap 13, the second link 22 can convert the linear motion of the first link 21 into rotational motion, allowing the flap 13 to rotate relative to the main wing 11, improving the flexibility and precision of the transmission mechanism 2 control.

[0107] Furthermore, the second link 22 is set at an angle to the rotation axis of the flap 13.

[0108] Specifically, the second link 22 is set at an angle to the rotation axis of the flap 13, which can be 90°. This creates a lever mechanism between the second link 22, the flap 13, and the rotation axis 14. This means that during opening, the applied torque of the downforce is in the same direction as the torque applied by the second link 22, providing an assist effect. A smaller input force can generate a larger output force, reducing the power required by the hydraulic mechanism 3 and improving its energy efficiency. Furthermore, it improves the response speed of the flap 13 during opening, further enhancing the response speed of the tail fin device.

[0109] Optionally, the tail fin body 1 includes a main wing 11 and a flap 13. The flap 13 is rotatably connected to the main wing 11. The first end of the second link 22 is rotatably connected to the flap 13. The second end of the second link 22 is rotatably connected to the second end of the third link 23. The first end of the third link 23 is rotatably connected to the second end of the first link 21. The hydraulic mechanism 3 can drive the first link 21 to move linearly, thereby driving the second link 22 and the third link 23 to rotate, so as to drive the flap 13 to rotate relative to the main wing 11.

[0110] like Figure 6As shown, the flap 13 can be equipped with a mounting base. The first end of the second link 22 is rotatably connected to the mounting base via a shaft. The second end of the second link 22 is rotatably connected to the second end of the third link 23 via a shaft. The first end of the third link 23 is rotatably connected to the second end of the first link 21 via a shaft. The output end 35 of the hydraulic mechanism 3 is connected to the first end of the first link 21. The output end 35 of the hydraulic mechanism 3 moves linearly, driving the first link 21 to move linearly. The first link 21 drives the third link 23 to rotate. The rotation of the third link 23 drives the second link 22 to rotate. The rotation of the second link 22 drives the flap 13 to rotate relative to the main wing 11, so that the tail wing body 1 is in a closed or open state. In practical applications, the hydraulic mechanism 3 drives the first link 21 to move linearly. Through the linkage of the second link 22 and the third link 23, the linear motion is converted into the rotational motion of the flap 13. This design makes the motion transmission more efficient and precise.

[0111] Furthermore, the third link 23 is arranged parallel to the rotation axis of the flap 13. While this creates a lever mechanism that requires more effort, it allows for a more compact structure of the first link 21, second link 22, and third link 23, reducing the volume of the transmission mechanism 2 and making the entire transmission mechanism 2 more compact, thus reducing space occupation and enabling complex motion control within a limited space. Moreover, by making the length of the drive cantilever 230 of the third link shorter than the length of the actuating cantilever 232, the stroke of the third link 23 can be shortened, thereby shortening the stroke of the output end 35 of the hydraulic mechanism 3. This reduces the amount of fluid required, decreases the volume and weight of the hydraulic mechanism 3, and improves the response speed of the hydraulic mechanism 3.

[0112] In some alternative embodiments, the tail fin body 1 further includes two ailerons 12, which are respectively disposed on both sides of the main fin 11 and the flap 13, and the flap 13 is rotatably connected to the two ailerons 12.

[0113] Specifically, such as Figure 4 As shown, the two ailerons 12 can be fixedly connected to both sides of the main wing 11 by means of bonding, welding, or other methods. A rotation shaft 14 can be erected between the two ailerons 12, and the flap 13 is rotatably connected to the rotation shaft 14, allowing the flap 13 to rotate relative to the main wing 11. In this embodiment, by providing ailerons 12 on both sides of the main wing 11 and the flap 13, the ailerons 12 can provide additional support points for the main wing 11 and the flap 13, increasing the stability of the tail fin body 1.

[0114] Optionally, the tail fin body 1 further includes a support 10, and the main fin 11 is fixedly mounted on the support 10.

[0115] Specifically, the support 10 can be a rigid component of any shape. One end of the support 10 can be fixedly connected to the main wing 11 by welding, bonding or other fixing methods. In this way, by setting the support 10, the main wing 11 can be provided with stable support, so that the support 10 and the tail wing body 1 form a solid integral structure, thereby improving the structural strength of the tail wing body 1.

[0116] In some alternative embodiments, the third link 23 is rotatably connected to the side of the bracket 10 near the flap 13.

[0117] Specifically, the bracket 10 has a through hole at one end near the flap 13, through which the connecting rod body 231 of the third connecting rod 23 passes, allowing the third connecting rod 23 to be rotatably connected. In this way, the bracket 10 can support the third connecting rod 23, improving the smoothness and reliability of the transmission mechanism 2 during its movement.

[0118] Optionally, the hydraulic cylinder 32 is fixedly mounted on the side of the bracket 10 near the main wing 11. The hydraulic cylinder 32 can be fixedly mounted on the side of the bracket 10 near the main wing 11 by means of welding, bolting, or other fixing methods. In this way, on the one hand, the bracket 10 can provide support for the hydraulic cylinder 32, and on the other hand, by mounting the hydraulic cylinder 32 on the side of the bracket 10 near the main wing 11, the stroke of the output end 35 of the hydraulic cylinder 32 can be minimized while ensuring that the hydraulic cylinder 32 has a certain stroke. This can reduce the amount of liquid required, reduce the size and weight of the hydraulic mechanism 3, and improve the response speed of the hydraulic mechanism 3.

[0119] Optionally, the hydraulic mechanism 3 further includes a base 34, the hydraulic pump 30 is disposed on the base 34, the bracket 10 is connected to the base 34, and the base 34 is used for fixed connection with the vehicle.

[0120] Specifically, such as Figures 1-6 As shown, the base 34 can be a rigid structural component of any shape. One end of the base 34 is fixedly connected to the bracket 10, and the other end is used to fix it to the vehicle. The hydraulic pump 30 is fixedly connected to the base 34. In this way, by setting the base 34, the tail wing body 1 and the hydraulic mechanism 3 can be fixedly supported, so that the entire tail wing device remains stable during operation.

[0121] In some alternative embodiments, there are at least two brackets 10 and bases 34.

[0122] Specifically, a bracket 10 and a base 34 form a group. The bracket 10 is fixedly connected to the tail fin body 1, and the base 34 is fixedly connected to the vehicle. In practical applications, setting multiple brackets 10 and bases 34 can provide more support points and enhance the stability of the entire tail fin device. For example, there can be two, three, or four brackets 10 and bases 34. The specific configuration can be determined according to actual needs.

[0123] Optionally, there are at least two hydraulic mechanisms 3, pressure holding valves, and transmission mechanisms 2.

[0124] Specifically, such as Figures 1-6 As shown, there can be at least two hydraulic mechanisms 3, pressure holding valves, and transmission mechanisms 2, which are spaced apart and connected to the tail fin body 1. One hydraulic mechanism 3, one pressure holding valve, and one transmission mechanism 2 form a group. Multiple groups of hydraulic mechanisms 3, pressure holding valves, and transmission mechanisms 2 can be controlled to operate simultaneously to open or close the tail fin body 1. In this embodiment, by setting multiple groups of hydraulic mechanisms 3, pressure holding valves, and transmission mechanisms 2, the simultaneous operation of multiple systems can quickly and stably open or close the tail fin body 1, thereby accelerating the response speed of the tail fin body 1. In situations requiring rapid adjustment, the coordinated operation of multiple systems can achieve the expected state more quickly, thus enabling the tail fin device to withstand greater air pressure.

[0125] It should be noted that the hydraulic mechanism 3, the pressure holding valve, and the transmission mechanism 2 can be 2, 3, 4, etc., and can be specifically set according to actual needs.

[0126] In summary, the tail fin device described in the embodiments of this application may include at least the following advantages:

[0127] In this embodiment, by setting a pressure-holding valve in the hydraulic mechanism 3, when the hydraulic mechanism 3 increases the liquid pressure to drive the tail wing body 1 to open, the pressure-holding valve can keep the high-pressure liquid in a high-pressure state. When the tail wing body 1 needs to be opened again, since the liquid is already in a high-pressure state, the hydraulic mechanism 3 can quickly provide sufficient pressure, reduce the pressure build-up time, improve the response speed of the tail wing device, and thus improve the safety and stability of the vehicle.

[0128] This application also provides a vehicle, which may specifically include the tail wing device described in any of the above embodiments.

[0129] The vehicle can be a sports car, racing car, etc.

[0130] It should be noted that in this embodiment, the structure of the tail fin is the same as that of the tail fin in any of the above embodiments, and its beneficial effects are similar, so it will not be described in detail here.

[0131] Optionally, the vehicle includes a vehicle body, a control system, and the rear wing device is disposed on the vehicle body. The control system is electrically connected to the rear wing device and is used to control the rear wing device to open or close.

[0132] Specifically, the base 34 of the rear wing device is fixedly connected to the vehicle body, thereby mounting the entire rear wing device on the vehicle body. The control system can be the vehicle's overall control system, electrically connected to the controller of the drive component 33 in the rear wing device. The control system and the motor controller can use the CAN communication protocol. The control system sends an execution command signal to the motor controller to open or close. The motor controller receives the execution command signal and, based on the status feedback of the hydraulic mechanism 3, outputs control commands to the drive component 33. These control commands include open and close commands. When the drive component 33 receives the open command, it drives the hydraulic pump 30 to work. The hydraulic pump 30 compresses the liquid, and the high-pressure liquid is transmitted to the hydraulic cylinder 32 through the first hydraulic pipe 310. The high-pressure liquid pushes the piston in the hydraulic cylinder 32 to move, and the piston movement drives the transmission mechanism 2 to move, causing the rear wing body 1 to open. When the drive component 33 receives the close command, it drives the hydraulic pump 30 to generate reverse pressure, which extracts the liquid from the hydraulic cylinder 32 through the second hydraulic pipe 311. The piston resets under the action of the reverse pressure, thereby causing the transmission mechanism 2 to drive the rear wing body 1 to close.
