[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0059] This application provides a tail fin assembly; please refer to [link / reference]. Figure 1 and Figure 3 .

[0060] The tail assembly has a length direction and a width direction, and includes a fixed wing body 1, a flap 2, a hydraulic power mechanism 4, and at least two transmission mechanisms 3.

[0061] In this embodiment, the flap 2 is located on one side of the fixed wing 1 in the width direction. The flap 2 and the fixed wing 1 can contact each other, allowing them to form a closed state and improving aesthetics. However, the flap 2 is not directly fixed to the fixed wing 1, enabling the flap 2 to move relative to the fixed wing 1 and adjust its angle to switch between downward and upward airflow guidance states. At least two transmission mechanisms 3 are fixed to the fixed wing 1, and the drive end of the transmission mechanism 3 is connected to the flap 2 to drive the flap 2 to rotate. In this embodiment, there are two transmission mechanisms 3, which are connected to the flap 2 at intervals along the length direction, ensuring that the force on the flap 2 is evenly distributed along the length direction, facilitating the rotation of the flap 2. In other embodiments, there may be three or more transmission mechanisms 3, which are connected to the flap 2 at intervals along the length direction. The specific number of transmission mechanisms 3 can be selected according to the length of the flap 2 in the length direction, and is not limited here. A hydraulic power mechanism 4 is connected to at least two transmission mechanisms 3 to drive the at least two transmission mechanisms 3 to move synchronously, so that the two transmission mechanisms 3 can receive the power of the hydraulic power mechanism 4 synchronously, thereby ensuring that the driving actions of the two transmission mechanisms 3 can be as consistent as possible, thereby ensuring that the force on the flap 2 in the length direction can be as consistent as possible, improving the smoothness of the flap 2's movement, and avoiding the situation where the flap 2 is not driven synchronously by the two transmission mechanisms 3, resulting in torque on the flap 2 or even damage.

[0062] The technical solution provided in this application drives at least two transmission mechanisms 3 to operate synchronously through a hydraulic power mechanism 4, thereby ensuring that multiple transmission mechanisms 3 connected to the hydraulic power mechanism 4 can synchronously drive the flaps 2 to rotate. This not only solves the problem that traditional tail fin components cannot switch between downward and upward modes in real time, but also ensures the consistency of the rotation of the flaps 2 driven by multiple transmission mechanisms 3, avoiding damage to the flaps 2 due to inconsistent actions of multiple transmission mechanisms 3.

[0063] In some embodiments, the hydraulic power mechanism 4 includes at least two hydraulic drive components 335. The oil circuits of the at least two hydraulic drive components 335 are connected so that the two hydraulic drive components 335 can synchronously receive the driving fluid; in this embodiment, the driving fluid is oil. The at least two hydraulic drive components 335 are correspondingly arranged with at least two transmission mechanisms 3. By connecting the oil circuits of the two hydraulic drive components 335, the two hydraulic drive components 335 can synchronously receive the oil and then operate synchronously, driving the corresponding transmission mechanisms 3. This allows the transmission mechanisms 3 to achieve synchronous movement of multiple transmission mechanisms 3 under the cooperative drive of the hydraulic drive components 335, thereby driving the flap 2 to rotate stably.

[0064] In some embodiments, the hydraulic power mechanism 4 includes a power unit 41, the hydraulic output end of which is connected to at least two hydraulic drive components 335, enabling the hydraulic output end of the power unit 41 to simultaneously drive the two hydraulic drive components 335 to move synchronously, thereby jointly rotating the flap 2. In this embodiment, the power unit 41 is hydraulically driven, which, compared to some mechanical drives such as motor-driven worm gears, has the advantages of faster response and more flexible structural arrangement.

[0065] In some embodiments, see Figures 1 to 3 The hydraulic power mechanism also includes at least two hydraulic pipes 42. The two ends of each hydraulic pipe 42 are connected to the hydraulic output end of the power unit 41 and the transmission mechanism 3, respectively, with each hydraulic pipe 42 corresponding to a specific transmission mechanism 3. By connecting the two hydraulic pipes 42 to the hydraulic output end of the power unit 41, the two hydraulic pipes 42 can simultaneously receive the power output from the power unit 41, and thus simultaneously transmit the power to their respective transmission mechanisms 3. This ensures that the two transmission mechanisms 3 can maintain as much consistency in their movements as possible, thereby allowing the flap 2 to rotate smoothly and minimizing the torque generated during the flap 2's rotation.

[0066] It should be noted that in other embodiments, the hydraulic power mechanism 4 may not use hydraulic power, but may use pneumatic power, worm gear, motor, etc. In this embodiment, hydraulic drive is preferred, which has the advantages of fast response time, more choices in structural settings, and less damage to the surface of the tail wing assembly.

[0067] In some embodiments, see Figure 4 The transmission mechanism 3 includes a linkage assembly 33 and a first connecting member 31. The input end of the hydraulic drive component 335 is connected to the hydraulic pipe 42. The drive end of the hydraulic drive component 335 is rotatably connected to the active end of the linkage assembly 33, driving the active end of the linkage assembly 33 to move. The driven end of the linkage assembly 33 is rotatably connected to the first connecting member 31, driving the first connecting member 31 to rotate. The first connecting member 31 is fixed to the inner surface of the flap 2. When the hydraulic power mechanism 4 transmits power to the hydraulic drive component 335 through the hydraulic pipe 42, the drive end of the hydraulic drive component 335 drives the linkage assembly 33 to move. The driven end of the linkage assembly 33 then moves with the active end, and then the driven end transmits power to the first connecting member 31, causing the first connecting member 31 to rotate. The rotation of the first connecting member 31 further drives the rotation of the flap 2, allowing the flap 2 to change its angle and shape in real time according to actual road conditions.

[0068] Furthermore, the linkage assembly 33 includes a support arm 331. The support arm 331 is fixed to the vehicle body and has a receiving cavity communicating with the outside. The support arm 331 includes a first housing 3311 and a second housing 3312, which are detachably connected to form the receiving cavity. Both the linkage assembly 33 and the first connector 31 are rotatably disposed within the receiving cavity. A portion of the first connector 31 is located outside the receiving cavity and connected to the flap 2. The connection between the first connector 31 and the flap 2 is a thermo-pressed connection, that is, a groove matching the shape of the first connector 31 is formed on the surface of the flap 2. The flap 2 is cured with the first connector 31 using one or more combinations of autoclave, resin transfer molding (RTM), wet molding, dry molding, and sheet molding compound (SMC). Compared to bolts, the hot pressing process makes the connection between the flap 2 and the first connecting piece 31 more stable and eliminates the torque generated by bolts. In particular, when the first connecting piece 31 drives the flap 2 to move, the torque between the first connecting piece 31 and the flap 2 is greatly reduced compared to the bolt fixing method, which is conducive to the long-term stable connection between the first connecting piece 31 and the flap 2.

[0069] Furthermore, please see Figure 4 The transmission mechanism 3 includes a second rotating shaft 3313, and the first connecting member 31 is provided with the first rotating shaft 311. The second rotating shaft 3313 is connected between the first housing 3311 and the second housing 3312 of the support arm 331. The second rotating shaft 3313 is located in the receiving cavity, and the first connecting member 31 is rotatably connected to the second rotating shaft 3313.

[0070] The linkage assembly 33 includes a first link 332 and a second link 333. The first end of the first link 332 is connected to the hydraulic power mechanism 4, and the first end of the second link 333 is rotatably connected to the second end of the first link 332. The second end of the second link 333 is connected to the flap 2. The first link 332 can drive the second link 333 to rotate under the drive of the hydraulic power mechanism 4, thereby causing the flap 2 to rotate.

[0071] Furthermore, the second end of the second link 333 is rotatably connected to the flap 2 via the first pivot 311, and the first end of the second link 333 is rotatably connected to the second end of the first link 332 via the third pivot 334.

[0072] It should be noted that the first end of the first link 332 refers to the end of the first link 332 away from the second link 333, and the second end of the first link 332 refers to the end of the first link 332 away from the hydraulic power mechanism 4. The first end of the second link 333 refers to the end of the second link 333 close to the hydraulic power mechanism 4, and the second end of the second link refers to the end of the second link 333 away from the hydraulic power mechanism 4.

[0073] For example, one end of the first link 332 is rotatably connected to the drive end of the hydraulic drive 335, and the other end is rotatably connected to the second link 333 via a third pivot 334. The end of the first link 332 away from the hydraulic drive 335 is passed through the third pivot 334, and the second link 333 is also passed through the third pivot 334, thus completing the rotatable connection of the first link 332 and the second link 333 to the third pivot 334. Because the third pivot 334 is not fixed to the support arm 331 or other components, the movement of the first link 332 and the second link 333 can drive the third pivot 334 to move synchronously. The end of the second link 333 away from the first link 332 is rotatably connected to the first connector 31 via a first pivot 311. The first connector 31 rotates around the second pivot 3313 as its axis of rotation, and under the action of the second link 333, it can rotate around the second pivot 3313, thereby changing the angle of the flap 2.

[0074] It should be noted that the shortest line connecting the first rotating shaft 311 and the third rotating shaft 334 intersects the motion trajectory of the second end of the first connecting rod 332, so that the second end of the first connecting rod 332 is not in the same direction as the shortest line connecting the first rotating shaft 311 and the third rotating shaft 334. When the driving force is applied to the first connecting rod 332, the second end of the first connecting rod 332 moves. Because the motion trajectory intersects the shortest line connecting the first rotating shaft 311 and the third rotating shaft 334, i.e., the angle is not 0, and in conjunction with the two ends of the second connecting rod 333 being rotatably connected to the first rotating shaft 311 and the third rotating shaft 334 respectively, the second connecting rod 333 can rotate around the first rotating shaft 311 under the action of the first connecting rod 332, thereby driving the first connecting member 31 to move. Because the first connecting member 31 is rotatably connected to the second rotating shaft 3313, when the first connecting member 31 is acted upon by the second connecting rod 333, it is restricted by the second rotating shaft 3313. This restricts the first connecting member 31 to convert the force of the second connecting rod 333 into the force required for rotation, thus enabling it to rotate. In this process, the second rotating shaft 3313 not only serves to connect and support the first connecting member 31, but also allows the first connecting member 31 to rotate around the second rotating shaft 3313.

[0075] To better understand the working process of the hydraulic drive component 335 driving the flap 2 through the linkage assembly 33, the following is a detailed explanation:

[0076] When the output end of the hydraulic drive 335 extends, it can push the first link 332 to move. During the movement of the first link 332, the driven end of the first link 332 will exert a pushing force on the third rotating shaft 334. Since the second link 333 is rotatably connected to the third rotating shaft 334, the second link 333 will tend to move with the first link 332. However, since the first rotating shaft 311 is fixed to the first connecting member 31, and the two ends of the second link 333 are rotatably connected to the first rotating shaft 311 and the third rotating shaft 334 respectively, the second link 333 will be restricted by the first rotating shaft 311. This will cause the second link 333 to change its tendency to move with the first link 332 to rotate around the first rotating shaft 311 as the rotation axis. The direction of rotation will be opposite to the direction of extension of the output end of the hydraulic drive 335. This will cause the second link 333 to pull the first connecting member 31 to move closer to the hydraulic drive 335. Furthermore, since the first connecting member 31 is fixed on the second rotating shaft 3313, the first connecting member 31 cannot move directly toward the hydraulic drive member 335. Instead, the movement is converted into a rotational motion around the second rotating shaft 3313. The rotation of the first connecting member 31 synchronously drives the flap 2 to rotate, so as to reduce the angle between the flap 2 and the horizontal plane.

[0077] When the output end of the hydraulic drive component 335 retracts, it can pull the first connecting rod 332 closer to the hydraulic drive component 335. During the movement of the first connecting rod 332, the driven end of the first connecting rod 332 will exert a pulling force on the third rotating shaft 334. Since the second connecting rod 333 is rotatably connected to the third rotating shaft 334, the second connecting rod 333 will tend to move with the first connecting rod 332. However, since the first rotating shaft 311 is fixed to the first connecting member 31, and the two ends of the second connecting rod 333 are... The first connecting rod 332 is not rotatably connected to the first rotating shaft 311 and the third rotating shaft 334. This restricts the movement of the second connecting rod 333 by the first rotating shaft 311, causing it to rotate around the first rotating shaft 311 as its axis of rotation. The direction of rotation is opposite to the direction of retraction of the output end of the hydraulic drive component 335, thus pushing the first connecting member 31 to move away from the hydraulic drive component 335. Furthermore, since the first connecting member 31 is fixed to the second rotating shaft 3313, it cannot move directly away from the hydraulic drive component 335. Instead, its movement is converted into rotation around the second rotating shaft 3313. The rotation of the first connecting member 31 synchronously drives the flap 2 to rotate, thereby increasing the angle between the flap 2 and the horizontal plane.

[0078] In some embodiments, see Figure 4The first connecting rod 332 includes a driving section 3321 and a driven section 3322. A fourth rotating shaft 3323 is provided within the receiving cavity. The driving section 3321 and the driven section 3322 are fixedly connected, and the connection point between the driving section 3321 and the driven section 3322 is rotatably connected to the fourth rotating shaft 3323. The line connecting the connection point formed by the driving section 3321 and the driven section 3322, the endpoint of the driving section 3321 away from the driven section 3322, and the endpoint of the driven section 3322 away from the driving section 3321 forms a triangle. For example, the axis of the fourth rotating shaft 3323 and the rotation axis of the first connecting rod 332 rotatably connected to the hydraulic drive component 335 intersect the same plane to form three intersection points, and the line connecting these three intersection points can form a triangle. By setting the first link 332 as a triangular structure, it is beneficial to improve the stress strength of the first link 332. The triangular structure of the first link 332 allows the first link 332 to have three connection points: the active segment 3321 is connected to the third rotating shaft 334, the driven segment 3322 is connected to the first rotating shaft 311, and the fixed connection position of the active segment 3321 and the driven segment 3322 is rotatably connected to the fourth rotating shaft 3323. This allows the first link 332 to be fixed through the fourth rotating shaft 3323, so that when the first link 332 is subjected to the force of the hydraulic drive component 335, the first link 332 can rotate around the fourth rotating shaft 3323.

[0079] Further, please see Figure 4 The first link 332 also includes a support section 3324, which is connected between the active section 3321 and the driven section 3322 to improve the connection strength between the active section 3321 and the driven section 3322 and to improve the overall strength of the first link 332.

[0080] In some embodiments, see Figure 5 The support arm 331 includes a fixing part 3314. The fixing part 3314 is fixed to the vehicle body. For example, the fixing part 3314 can be fixed to the tailgate of the vehicle body. The surface of the fixing part 3314 is provided with a guide surface 3315 to make the fixing part 3314 teardrop-shaped. The guide surface 3315 is used to divert at least part of the airflow passing through the fixing part 3314, so that when the airflow passes through the support arm 331, the airflow smoothness when it encounters the fixing part 3314 is improved, and the wind resistance caused by the obstruction of the fixing part 3314 is reduced.

[0081] In some embodiments, a fixing groove is provided on the inner side of the first housing 3311 and / or the second housing 3312, and the hydraulic drive component 335 is disposed in the fixing groove to fix the hydraulic drive component 335 and prevent the hydraulic drive component 335 from shaking during operation.

[0082] In some embodiments, see Figure 4The transmission mechanism 3 also includes a second connecting member 32, which is fixed to the first housing 3311 and the second housing 3312 by bolts. For example, the bolts pass through the second connecting member 32, and then both ends of the pin are fixed to the inner sides of the first housing 3311 and the second housing 3312, respectively, thereby allowing the second connecting member 32 to be installed within the receiving cavity of the support arm 331. Furthermore, a portion of the second connecting member 32 protrudes from the outside of the support arm 331 through the receiving cavity for connection with the fixed wing body 1. The connection method can be achieved by one or more combinations of autoclave, resin transfer molding (RTM), wet molding, dry molding, and sheet molding compound (SMC) processes to solidify the fixed wing body 1 and the second connecting member 32.

[0083] In some embodiments, see Figure 3 The tail wing assembly also includes a first side wing 8 and a second side wing 9, which are arranged opposite each other along the length direction. The two ends of the fixed wing body 1 are fixedly connected to the first side wing 8 and the second side wing 9 respectively, and the two ends of the flap 2 are movably connected to the first side wing 8 and the second side wing 9 respectively, so as to ensure that the flap 2 can rotate under the action of the transmission mechanism 3.

[0084] In some embodiments, see Figure 6 and Figure 7The power unit 41 includes a main delivery pipeline 411, a housing 412, a filter 413, a hydraulic pump 414, a hydraulic valve 415, a throttle valve 416, an overflow valve 417, and delivery branch pipelines 418. The output end of the main delivery pipeline 411 is connected to at least two hydraulic pipes 42, allowing the driving fluid delivered by the main delivery pipeline 411 to be simultaneously distributed to the at least two connected hydraulic pipes 42. Each hydraulic pipe 42 is connected to a corresponding transmission mechanism 3, enabling at least two transmission mechanisms 3 to receive the driving fluid synchronously, thereby improving the driving consistency of multiple transmission mechanisms 3. The housing 412 is used to hold the driving fluid and is connected to the input end of the main delivery pipeline 411, providing the driving fluid to the main delivery pipeline 411. The filter 413, hydraulic pump 414, hydraulic valve 415, and throttle valve 416 are sequentially arranged on the main delivery pipeline 411 from the input end to the output end. The driving fluid in housing 412 flows sequentially through main delivery pipeline 411, passing through filter 413, hydraulic pump 414, hydraulic valve 415, and throttle valve 416, ultimately diverting the driving fluid into multiple branch delivery pipelines 418. Filter 413 is located between housing 412 and hydraulic pump 414, ensuring the driving fluid is filtered before entering hydraulic pump 414, preventing impurities in the driving fluid from affecting subsequent machinery. Hydraulic pump 414 provides the flow power for the driving fluid. Hydraulic valve 415 opens or closes main delivery pipeline 411. Throttle valve 416 controls the flow rate of the driving fluid in main delivery pipeline 411, thereby controlling the extension and retraction amplitude and speed of the delivery end of hydraulic drive component 335 in transmission mechanism 3. The two ends of the delivery branch pipe 418 are connected to the main delivery pipe 411 and the housing 412 respectively. The overflow valve 417 is installed on the delivery branch pipe 418 to prevent excessive pressure rise in the power unit 41 and to prevent pipe rupture and damage to the hydraulic pump 414.

[0085] Furthermore, the delivery branch line 418 is connected between the hydraulic pump 414 and the hydraulic valve 415. When the output pressure of the hydraulic pump 414 suddenly rises beyond the system's capacity (such as due to hydraulic pump 414 failure, pipeline blockage, or pressure spike caused by sudden load changes), the relief valve 417 quickly opens, diverting excess pressurized oil back to the housing 412 via the delivery branch line 418, limiting the system pressure within a safe threshold, and preventing pipeline rupture, pump damage, and other component failures.

[0086] In some embodiments, the power unit 41 further includes a motor 7, the power output end of which is connected to two transmission mechanisms 3 respectively. In this embodiment, the power output end of the motor 7 is connected to a hydraulic pump 414 to change the internal cavity volume of the hydraulic pump 414, thereby realizing the functions of the hydraulic pump 414 in suction and discharge.

[0087] In some embodiments, the power unit 41 is fixed to the sheet metal part 5 of the vehicle body to improve the stability of the power unit 41. The motor 7 in the power unit 41 is mounted on the sheet metal part 5 and is used to drive the power unit 41 to deliver or recover the driving fluid. Exemplarily, the motor 7 is connected to the input shaft of the hydraulic pump 414 via a coupling. When the motor 7 is energized and rotates, the torque it generates is directly transmitted to the input shaft of the hydraulic pump 414 via the coupling. The rotational motion of the rotor of the motor 7 drives the gears, blades, or plungers and other components inside the hydraulic pump 414 to move according to a specific pattern, causing the pump chamber volume to change periodically. During the oil suction phase, the pump chamber volume increases to form a negative pressure, drawing the driving fluid from the housing 412 into the pump chamber; during the oil pressure phase, the pump chamber volume decreases, pressurizing the drawn-in driving fluid and forcing it to flow through the oil outlet into the hydraulic circuit, thereby providing a continuous and stable pressure oil flow for the entire hydraulic system and driving the hydraulic cylinder and other actuators to work. The motor 7 reverses to drive the hydraulic pump 414, changing the oil flow direction and pressure, causing the hydraulic cylinder piston rod to retract, which in turn drives the flap 2 back to the closed angle, generating the required downward pressure. Furthermore, by fixing both the power unit 41 and the motor 7 to the sheet metal component 5, the strength of the sheet metal component 5 is utilized to resist any deformation of the mounting point that may be caused by the reverse rotation of the motor 7.

[0088] Furthermore, a buffer pad 6 is provided between the power unit 41 and the sheet metal part 5. The buffer pad 6 can be a soft rubber pad, foam, etc., which helps to reduce the vibration of the power unit 41 during operation.

[0089] In some embodiments, both the fixed wing body 1 and the flaps 2 are made of lightweight, high-strength carbon fiber composite material to reduce the deformation of the tail wing assembly under high wind pressure and ensure the stability of downforce during vehicle operation. Downforce refers to the downward pressure caused by the change in airflow speed at the upper and lower ends of the tail wing assembly due to the tail wing assembly structure, resulting in different air pressures at the upper and lower ends of the wing surface.

[0090] Please see Figure 8 and Figure 9 The tail wing assembly can switch between a closed state and an open state in real time. The working process of the tail wing assembly provided in this application is as follows:

[0091] When the tail fin assembly switches from the closed state to the open state, the control motor 7 rotates forward, driving the power unit 41 to deliver driving fluid to the hydraulic drive component 335 in the transmission mechanism 3. The hydraulic drive component 335 can be a hydraulic cylinder. Driven by the driving fluid, the output end of the hydraulic drive component 335 extends, thereby driving the first connecting rod 332 to rotate about the fourth rotating shaft 3323 in a direction away from the hydraulic drive component 335. This, in turn, drives the second connecting rod 333 to rotate in the direction of the hydraulic drive component 335. The second connecting rod 333 drives the first connecting member 31 to rotate, and the first connecting member 31 then drives the flap 2 to rotate and open.

[0092] When the tail fin assembly switches from the open state to the closed state, the control motor 7 reverses, driving the power unit 41 to draw the driving fluid from the hydraulic drive unit 335 back into the power unit 41. The space in the hydraulic drive unit 335 used to store the driving fluid is under negative pressure, and the output end of the hydraulic drive unit 335 retracts, thereby driving the first connecting rod 332 to rotate about the fourth rotating shaft 3323 in the direction of the hydraulic drive unit 335. This, in turn, drives the second connecting rod 333 to rotate in the direction away from the hydraulic drive unit 335. The second connecting rod 333 drives the first connecting member 31 to rotate, and the first connecting member 31 then drives the flap 2 to rotate and close.
