Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to an electric tail wing hinge structure, an electric tail wing, and a vehicle. Background Technology

[0002] As intelligent and electrification technologies are increasingly applied in the automotive field, electric rear wings are becoming more and more widely used. When a vehicle is traveling at high speed, the electric rear wing deploys, and the spoiler creates downward pressure due to air resistance, offsetting some of the lift and effectively controlling downforce. This reduces the drag coefficient, lowers the vehicle's air resistance, and increases high-speed stability. However, in these technologies, electric rear wings have low self-locking performance in both open and / or closed states, making it difficult to maintain their current position. The spoiler's stability is also low, making it prone to wobbling, which affects reliability and safety. Utility Model Content

[0003] In view of this, embodiments of this application aim to provide an electric tail wing hinge structure, an electric tail wing, and a vehicle capable of achieving two-stage self-locking in the open and / or closed states.

[0004] To achieve the above objectives, one embodiment of this application provides an electric tail wing hinge structure, comprising:

[0005] Fixed base;

[0006] An input shaft, rotatably connected to the fixed base; a connecting plate, used to connect to the tail spoiler of the electric tail wing;

[0007] The linkage assembly includes a drive rod, a first link, a second link, and a third link. One end of the drive rod is connected to the input shaft. One end of the first link and the second link are respectively hinged to the fixed base, and the other end is respectively hinged to the end of the connecting plate away from the tail spoiler. One end of the third link is hinged to the end of the drive rod away from the input shaft, and the other end is hinged to the second link.

[0008] The input shaft can drive the linkage assembly and the connecting plate to rotate, so that the tail spoiler can switch between an open state and a closed state.

[0009] When the tail spoiler is in the open and / or closed state, the active rod and the third connecting rod are collinear, and the active rod, the third connecting rod, the second connecting rod, and the fixed base form a triangular self-locking structure; the connecting plate is collinear with the first connecting rod or the second connecting rod, and the first connecting rod, the second connecting rod, the third connecting rod, and the fixed base form a triangular self-locking structure.

[0010] In some implementations, when the tail spoiler is in the open state, the angle between the active rod and the third link is 180°, and the angle between the connecting plate and the first link is 180°; when the tail spoiler is in the closed state, the angle between the active rod and the third link is 180°, and the angle between the connecting plate and the second link is 180°.

[0011] In some implementations, the connection position between the second link and the third link is located between the connection position between the second link and the connecting plate and the connection position between the second link and the fixed base.

[0012] In some implementations, the connection point between the second link and the third link is located at the midpoint of the line connecting the connection point between the second link and the connecting plate and the connection point between the second link and the fixed base.

[0013] In some implementations, the second link is a one-piece structure.

[0014] In some embodiments, the second link includes a first branch and a second branch with a split design, the first branch being connected to the second branch, the end of the first branch away from the second branch being hinged to the fixed seat, the end of the second branch away from the first branch being hinged to the connecting plate, and the third link being hinged at the connection between the first branch and the second branch.

[0015] In some implementations, there is no relative movement between the first branch and the second branch, and the first branch and the second branch are always collinear and do not overlap; or, the first branch and the second branch are hinged.

[0016] In some implementations, one end of the drive rod is provided with a through connecting hole, and the input shaft is provided with a pin, which passes through the fixed base and the connecting hole;

[0017] The other end of the active rod is provided with a pin, which passes through the third connecting rod to realize the hinge connection between the active rod and the third connecting rod.

[0018] In some implementations, the active rod is a one-piece structure.

[0019] In some implementations, the mounting base includes a bottom wall, a first side wall, and a second side wall. The first side wall and the second side wall are disposed opposite each other along a first direction and are respectively connected to the top side of the bottom wall. The bottom wall, the first side wall, and the second side wall define an installation space. The active rod is disposed within the installation space. The end of the first connecting rod away from the connecting plate is disposed in the installation space and hinged to the first side wall. The end of the second connecting rod away from the connecting plate is disposed in the installation space and hinged to the second side wall. The first direction is perpendicular to the top and bottom direction of the electric tail fin.

[0020] Another embodiment of this application provides an electric tail fin, including:

[0021] Rear spoiler;

[0022] Drive motor;

[0023] And the electric tail wing hinge structure described in any embodiment of this application;

[0024] The tail spoiler is connected to the side of the connecting plate away from the link assembly, and the drive motor is powered to the end of the input shaft away from the link assembly.

[0025] Another embodiment of this application provides a vehicle, including a vehicle body and an electric tail wing as described in any embodiment of this application, wherein the mounting base is connected to the vehicle body.

[0026] The electric tail wing hinge structure provided in this application embodiment transmits the rotation of the input shaft to the tail wing spoiler through a multi-link structure formed by the linkage assembly and the connecting plate, so that the tail wing spoiler can be opened or closed. When the tail wing spoiler is in the open and / or closed state, two triangular self-locking structures are formed by the collinearity of the active rod and the third link, and the collinearity of the connecting plate and the first or second link, which restricts the relative movement of the linkage assembly and the connecting plate. The electric tail wing hinge structure has high self-locking performance, which enables the tail wing spoiler to be stably maintained in the current position in the open and / or closed state, reducing the probability of the tail wing spoiler losing stability due to external pressure and rain and snow forces, and increasing the safety of the tail wing spoiler in use.

[0044] This application provides an embodiment of an electric tail wing hinge structure 10. Please refer to... Figures 1 to 14 The electric tail wing hinge structure 10 includes a fixed base 11, an input shaft 12, a connecting plate 13, and a connecting rod assembly 14.

[0045] The input shaft 12 is rotatably connected to the fixed base 11.

[0046] The fixed base 11 can serve as a fixed mounting structure, providing a stable mounting position and support point for moving parts such as the input shaft 12 and the connecting rod assembly 14.

[0047] For example, the mounting base 11 can be connected to the vehicle body to increase the rigidity of the electric rear wing hinge structure 10, reduce the vibration and displacement that may occur during the operation of the electric rear wing hinge structure 10, and improve the working stability of the electric rear wing hinge structure 10.

[0048] The input shaft 12 is rotatably connected to the fixed base 11, meaning that the input shaft 12 can rotate relative to the fixed base 11, thereby driving the connecting rod assembly 14 and the connecting plate 13 to rotate.

[0049] The input shaft 12 can be connected to the drive motor of the electric tail fin to obtain rotational driving force.

[0050] The rotational connection between the input shaft 12 and the fixed seat 11 is not limited. For example, it can be a bearing connection, a pivot connection, etc., and there is no limitation here.

[0051] The connecting plate 13 is used to connect to the tail spoiler of the electric tail wing.

[0052] The linkage assembly 14 includes a drive rod 141, a first link 142, a second link 143, and a third link 144. One end of the drive rod 141 is connected to the input shaft 12. One end of the first link 142 and the second link 143 are respectively hinged to the fixed base 11, and the other end is respectively hinged to the end of the connecting plate 13 away from the tail spoiler. One end of the third link 144 is hinged to the end of the drive rod 141 away from the input shaft 12, and the other end is hinged to the second link 143.

[0053] In other words, the linkage assembly 14 and the connecting plate 13 can form a multi-link mechanism.

[0054] The input shaft 12 can drive the linkage assembly 14 and the connecting plate 13 to rotate, so that the tail spoiler can switch between the open and closed states.

[0055] Specifically, the rotational motion of the input shaft 12 is transmitted to the third link 144 through the active link 141, and then to the second link 143, the first link 142 and the connecting plate 13 through the third link 144, thereby transmitting the power of the input shaft 12 to the tail spoiler, causing the tail spoiler to open or close.

[0056] Understandably, when a vehicle is traveling at high speed, the opening of the rear spoiler can change the direction of airflow behind the vehicle, creating a low-pressure area above the vehicle and a high-pressure area below the vehicle. This gives the vehicle additional downforce, increasing the friction between the tires and the ground, thereby improving the vehicle's grip and stability, and helping to reduce air resistance.

[0057] When the tail spoiler is in the open and / or closed state, the active rod 141 and the third link 144 are collinear, and the active rod 141, the third link 144, the second link 143, and the fixed seat 11 form a triangular self-locking structure; the connecting plate 13 is collinear with the first link 142 or the second link 143, and the first link 142, the second link 143, the third link 144, and the fixed seat 11 form a triangular self-locking structure.

[0058] It is understandable that the tail spoiler can form two triangular self-locking structures when it is open, or when it is closed, or when it forms two triangular self-locking structures in both the open and closed states.

[0059] For example, please refer to Figures 4 to 7 In both the open and closed states, the electric tail wing hinge structure 10 forms two triangular self-locking structures.

[0060] The collinearity of the driving rod 141 and the third link 144 means that the connection positions A between the driving rod 141 and the input shaft 12, B between the driving rod 141 and the third link 144, and C between the third link 144 and the second link 143 are all on the same straight line. The included angle between the driving rod 141 and the third link 144 can be 0° or 180°.

[0061] Please see Figures 4 to 7 The active rod 141, the third link 144, the second link 143, and the fixed seat 11 form a triangular self-locking structure. This means that the connection positions A between the active rod 141 and the input shaft 12, C between the third link 144 and the second link 143, and D between the second link 143 and the fixed seat 11 can serve as the three vertices of the triangle. The lines connecting the connection positions A between the active rod 141 and the input shaft 12, B between the active rod 141 and the third link 144, and C between the third link 144 and the second link 143 can form one side of the triangle. The lines connecting the connection positions C between the third link 144 and the second link 143, and D between the second link 143 and the fixed seat 11 can form another side of the triangle. The lines connecting the connection positions D between the second link 143 and the fixed seat 11, and A between the active rod 141 and the input shaft 12 can form yet another side of the triangle.

[0062] The connection plate 13 and the first connecting rod 142 are collinear, meaning that the connection position F between the connection plate 13 and the first connecting rod 142, the connection position E between the connection plate 13 and the second connecting rod 143, and the connection position G between the first connecting rod 142 and the fixed base 11 are all on the same straight line. In this case, the included angle between the connection plate 13 and the first connecting rod 142 can be 0° or 180°.

[0063] The connection plate 13 and the second connecting rod 143 are collinear, meaning that the connection position E between the connection plate 13 and the second connecting rod 143, the connection position F between the connection plate 13 and the first connecting rod 142, and the connection position D between the second connecting rod 143 and the fixed base 11 are all on the same straight line. In this case, the included angle between the connection plate 13 and the second connecting rod 143 can be 0° or 180°.

[0064] When the connecting plate 13 and the first connecting rod 142 are collinear, the first connecting rod 142, the second connecting rod 143, the third connecting rod 144, and the fixed seat 11 form a triangular self-locking structure. This means that the connection position G between the first connecting rod 142 and the fixed seat 11, the connection position E between the connecting plate 13 and the second connecting rod 143, and the connection position D between the second connecting rod 143 and the fixed seat 11 can serve as the three vertices of the triangle. The line connecting the connection position G between the first connecting rod 142 and the fixed seat 11, the connection position F between the first connecting rod 142 and the connecting plate 13, and the connection position E between the connecting plate 13 and the second connecting rod 143, and the connection position D between the second connecting rod 143 and the fixed seat 11 can form one side of the triangle. The line connecting the connection position E between the connecting plate 13 and the second connecting rod 143, and the connection position D between the second connecting rod 143 and the fixed seat 11, and the connection position G between the first connecting rod 142 and the fixed seat 11 can form another side of the triangle.

[0065] When the connecting plate 13 and the second connecting rod 143 are collinear, the first connecting rod 142, the second connecting rod 143, the third connecting rod 144, and the fixed seat 11 form a triangular self-locking structure. This means that the connection position G between the first connecting rod 142 and the fixed seat 11, the connection position F between the connecting plate 13 and the first connecting rod 142, and the connection position D between the second connecting rod 143 and the fixed seat 11 can serve as the three vertices of the triangle. The line connecting the connection position G between the first connecting rod 142 and the fixed seat 11 and the connection position F between the first connecting rod 142 and the connecting plate 13 can form one side of the triangle. The line connecting the connection position F between the first connecting rod 142 and the connecting plate 13, the connection position E between the connecting plate 13 and the second connecting rod 143, and the connection position D between the second connecting rod 143 and the fixed seat 11 can form another side of the triangle. The line connecting the connection position D between the second connecting rod 143 and the fixed seat 11 and the connection position G between the first connecting rod 142 and the fixed seat 11 can form yet another side of the triangle.

[0066] When the rear spoiler is in the open position, please refer to Figure 4 and Figure 5 It is possible that the connecting plate 13 and the first connecting rod 142 are collinear. When the tail spoiler is in the closed state, please refer to [the relevant documentation]. Figure 6 and Figure 7 It is possible that the connecting plate 13 and the second connecting rod 143 are collinear.

[0067] Please see Figures 1 to 3When the tail spoiler is in an intermediate state that is neither fully open nor fully closed, the active rod 141 and the third link 144 are not collinear, the connecting plate 13 is not collinear with the first link 142, and the connecting plate 13 is not collinear with the second link 143. At this time, the active rod 141, the third link 144, the second link 143 and the fixed seat 11 form a quadrilateral structure, and the first link 142, the connecting plate 13, the second link 143 and the fixed seat 11 form a quadrilateral structure. The electric tail spoiler hinge structure 10 does not have structural stability.

[0068] Please refer to the following for the rear spoiler's on and / or off state: Figures 4 to 7 The electric tail wing hinge structure 10 forms a double-stage self-locking structure through two triangular self-locking structures. By utilizing the stability of triangles, the relative movement of the connecting rod assembly 14 and the connecting plate 13 is restricted, so that the tail wing spoiler can remain in the set position in the open and / or closed state and will not be disturbed by external forces.

[0069] Understandably, in related technologies, the tail spoiler can only form a single-stage self-locking state when it is open and / or closed. The self-locking performance is low, and it cannot reliably maintain the current state. The stability of the tail spoiler is low, and it is prone to shaking, which affects the reliability and safety of use.

[0070] The electric tail wing hinge structure 10 provided in this application embodiment transmits the rotation of the input shaft 12 to the tail wing spoiler through a multi-link structure formed by the connecting rod assembly 14 and the connecting plate 13, so that the tail wing spoiler can be opened or closed. When the tail wing spoiler is in the open and / or closed state, two triangular self-locking structures are formed by the collinearity of the active rod 141 and the third connecting rod 144, and the collinearity of the connecting plate 13 and the first connecting rod 142 or the second connecting rod 143, which restricts the relative movement of the connecting rod assembly 14 and the connecting plate 13. The electric tail wing hinge structure 10 has high self-locking performance, which enables the tail wing spoiler to be stably maintained in the current position in the open and / or closed state, reducing the probability of the tail wing spoiler losing stability due to external pressure and rain and snow forces, and increasing the safety of the tail wing spoiler.

[0071] In some embodiments, please refer to Figure 4 and Figure 5 When the tail spoiler is in the open state, the angle between the active rod 141 and the third connecting rod 144 is 180°, and the angle between the connecting plate 13 and the first connecting rod 142 is 180°. When the tail spoiler is in the closed state, please refer to [link to relevant documentation]. Figure 6 and Figure 7 The angle between the active rod 141 and the third link 144 is 180°, and the angle between the connecting plate 13 and the second link 143 is 180°.

[0072] In other words, the electric tail wing hinge structure 10 can form two triangular self-locking structures in both the open and closed states of the tail wing spoiler.

[0073] When the tail spoiler is in the open and closed states, the angle between the active rod 141 and the third link 144 is 180°, meaning that the active rod 141 and the third link 144 will not overlap. This makes it easier to arrange the link assembly 14 in a compact space, reducing the extension length of the active rod 141 and the third link 144, and increasing the output force under the same input torque.

[0074] In some embodiments, please refer to 1 to Figure 7 The connection position C between the second link 143 and the third link 144 is located between the connection position E between the second link 143 and the connecting plate 13 and the connection position D between the second link 143 and the fixed seat 11.

[0075] That is, the connection position between the second link 143 and the third link 144 will not be located outside the connection position between the second link 143 and the connecting plate 13 and the connection position between the second link 143 and the fixed seat 11. In this way, the force distribution can be more uniform, increasing the flexibility and stability of the electric tail wing hinge structure 10. At the same time, the overall size of the second link 143 can be smaller, reducing the space required for the electric tail wing hinge structure 10 and facilitating its arrangement in a compact space.

[0076] In some embodiments, please refer to Figures 4 to 7 The connection position C between the second link 143 and the third link 144 is located at the midpoint of the line connecting the second link 143 and the connecting plate 13 at the connection position E and the second link 143 and the fixed seat 11 at the connection position D.

[0077] This allows for a more even distribution of force on the second link 143, reducing local stress concentration, facilitating a more stable self-locking structure, and extending the service life of the electric tail wing hinge structure 10. Furthermore, the connection point between the second link 143 and the third link 144 is located at the midpoint of the line connecting the second link 143 to the connecting plate 13 and the second link 143 to the fixed base 11, making the connection relationship of the electric tail wing hinge structure 10 more symmetrical and intuitive.

[0078] In some embodiments, please refer to Figure 13 The second connecting rod 143 is a one-piece structure.

[0079] In other words, the second link 143 is manufactured as a single piece. This eliminates weak points caused by connection or welding processes, increases the structural strength of the second link 143, and allows it to better withstand forces during movement, reducing the risk of breakage or damage. Simultaneously, the one-piece design of the second link 143 also reduces assembly errors, improves the self-locking reliability of the electric tail wing hinge structure 10, and reduces the number of links required for the electric tail wing hinge structure 10, resulting in a simpler and more reliable overall layout.

[0080] In other embodiments, the second link 143 includes a first branch and a second branch with a split design. The first branch is connected to the second branch. The end of the first branch away from the second branch is hinged to the fixed seat 11. The end of the second branch away from the first branch is hinged to the connecting plate 13. The third link 144 is hinged at the connection between the first branch and the second branch.

[0081] In other words, in this embodiment, the second connecting rod 143 is a split structure. The first and second connecting rods are manufactured separately and then assembled to form the second connecting rod 143.

[0082] In this embodiment, the connection position of the second link 143 with the connecting plate 13 and the third link 144 can be adjusted by adjusting the size of the first and second links and their connection position, thereby enabling the electric tail wing hinge structure 10 to adapt to different layout spaces and functional requirements, and increasing the adaptability of the electric tail wing hinge structure 10.

[0083] The connection method between the first and second branch links is not limited, as long as they are collinear when the tail spoiler is in the open and closed states.

[0084] In some embodiments, there is no relative movement between the first and second branch rods, and the first and second branch rods are always collinear and do not overlap.

[0085] In this embodiment, the first and second segments can be considered as a continuous whole, and there is no relative motion between the first and second segments. The overall structure of the electric tail wing hinge structure 10 is simple, the movement mode is simple, the force transmission is more direct and effective, and the additional stress caused by deflection is reduced.

[0086] In other embodiments, the first branch rod is hinged to the second branch rod.

[0087] In this embodiment, there is a certain relative movement between the first and second branch rods, and the electric tail wing hinge structure 10 is more flexible and can better adapt to different working states or installation conditions, as long as it can be collinear when the tail wing spoiler is in the open and closed states.

[0088] In some embodiments, please refer to Figures 1 to 7 , Figure 9 and Figure 10 One end of the active rod 141 is provided with a through connecting hole 141a, and the input shaft 12 is provided with a pin 121, which passes through the fixed seat 11 and the connecting hole 141a.

[0089] The other end of the active rod 141 is provided with a pin 141b, which passes through the third link 144 to realize the hinge connection between the active rod 141 and the third link 144.

[0090] Understandably, after the pin 121 and the connecting hole 141a are engaged, there will be no relative sliding between the input shaft 12 and the drive rod 141, thus increasing the driving reliability of the input shaft 12.

[0091] In this embodiment, one end of the active rod 141 is connected to the input shaft 12 through the connecting hole 141a, and the other end is hinged to the third connecting rod 144 through the pin 141b. In this way, the active rod 141 can have greater structural strength, reducing the phenomenon of weak strength caused by the use of hole structure connection at both ends of the active rod in related technologies. While ensuring that the active rod 141 has sufficient structural strength, the length of the active rod 141 can be compressed to the maximum extent, thereby increasing the output force of the active rod 141 under the same input torque, thereby improving the operating efficiency of the electric tail wing hinge structure 10.

[0092] In some embodiments, please refer to Figure 10 The active rod 141 is an integral structure.

[0093] In other words, the drive rod 141 is manufactured as a single piece. This eliminates weak points caused by connection or welding processes, increases the structural strength of the drive rod 141, and allows it to better withstand forces during movement, reducing the risk of breakage or damage. Simultaneously, the one-piece design of the drive rod 141 reduces assembly errors, improves the self-locking reliability of the electric tail wing hinge structure 10, and also reduces the number of connecting rods required for the electric tail wing hinge structure 10, resulting in a simpler and more reliable overall layout.

[0094] For example, the drive rod 141 is a one-piece die-cast structure.

[0095] In some embodiments, please refer to Figure 1 and Figure 8The mounting base 11 includes a bottom wall 11a, a first side wall 11b, and a second side wall 11c. The first side wall 11b and the second side wall 11c are arranged opposite each other along the first direction X1 and are respectively connected to the top side of the bottom wall 11a. The bottom wall 11a, the first side wall 11b, and the second side wall 11c define an installation space 11d. The active rod 141 is disposed in the installation space 11d. The end of the first connecting rod 142 away from the connecting plate 13 is disposed in the installation space 11d and is hinged to the first side wall 11b. The end of the second connecting rod 143 away from the connecting plate 13 is disposed in the installation space 11d and is hinged to the second side wall 11c. The first direction X1 is perpendicular to the top and bottom direction X2 of the electric tail wing.

[0096] In this embodiment, the active rod 141, the first connecting rod 142, and the second connecting rod 143 can be installed and positioned through the first sidewall 11b and the second sidewall 11c. At the same time, by utilizing the installation space 11d formed within the fixed base 11, the portion of the connecting rod assembly 14 located outside the fixed base 11 is reduced, making the overall layout of the electric tail wing hinge structure 10 more compact. Of course, this also reduces the probability of motion interference between the first connecting rod 142 and the second connecting rod 143, ensuring smooth and reliable movement of the connecting rod assembly 14 within a limited space.

[0097] The hinge connection method between the connecting rod assembly 14 and the fixed seat 11 is not limited.

[0098] For example, please refer to Figure 1 , Figure 8 , Figure 12 and Figure 13 The fixed base 11 is provided with a first mounting hole 11e, a second mounting hole 11f and a third mounting hole 11g. The second mounting hole 11f penetrates the first side wall 11b, and the first mounting hole 11e and the third mounting hole 11g penetrate the second side wall 11c. The pin 121 of the input shaft 12 passes through the second mounting hole 11f and engages with the connecting hole 141a of the drive rod 141.

[0099] The first connecting rod 142 is provided with a first through hole 142a, and the second connecting rod 143 is provided with a fifth through hole 143c. The connecting rod assembly 14 may include a first rotating shaft and a second rotating shaft. The first rotating shaft passes through the second mounting hole 11f and the first through hole 142a to realize the hinge connection between the first connecting rod 142 and the fixed seat 11. The second rotating shaft passes through the third mounting hole 11g and the fifth through hole 143c to realize the hinge connection between the second connecting rod 143 and the fixed seat 11.

[0100] The specific construction of the connecting plate 13 is not limited; for example, please refer to [reference needed]. Figure 11The connecting plate 13 may include a first connecting portion 131 and a second connecting portion 132 that are connected to each other. The connecting plate 13 is hinged to the first connecting rod 142 and the second connecting rod 143 respectively through the first connecting portion 131, and the connecting plate 13 is connected to the tail spoiler through the second connecting portion 132. The first connecting portion 131 and the second connecting portion 132 may be angled to facilitate cooperation with the tail spoiler, so as to enable the opening and closing of the tail spoiler within a small rotation angle range.

[0101] For example, please refer to Figure 11 The connecting plate 13 may be provided with a first through hole 13a, a second through hole 13b, and a third through hole 13c. The first through hole 13a and the second through hole 13b pass through the first connecting part 131, and the third through hole 13c passes through the second connecting part 132. The tail spoiler is connected to the connecting plate 13 through the third through hole 13c, and the connection method may be screwed or the like. The number of third through holes 13c may be one or more. For example, the number of third through holes 13c is two.

[0102] Please see Figure 1 , Figure 12 and Figure 13 The first connecting rod 142 is provided with a second through hole 142b, and the second connecting rod 143 is provided with a third through hole 143a. The connecting rod assembly 14 may include a third rotating shaft and a fourth rotating shaft. The third rotating shaft passes through the second through hole 142b and the first through hole 13a to realize the hinge connection between the first connecting rod 142 and the connecting plate 13. The fourth rotating shaft passes through the third through hole 143a and the second through hole 13b to realize the hinge connection between the second connecting rod 143 and the connecting plate 13.

[0103] For example, please refer to Figure 13 and Figure 14 The second link 143 is also provided with a fourth through hole 143b, and the third link 144 is provided with a sixth through hole 144a and a seventh through hole 144b. The link assembly 14 may include a fifth rotating shaft, which passes through the fourth through hole 143b and the sixth through hole 144a to realize the hinge connection between the third link 144 and the second link 143. The pin 141b of the driving link 141 passes through the sixth through hole 144a to realize the hinge connection between the driving link 141 and the third link 144.

[0104] In other words, in this embodiment, the first connecting rod 142, the second connecting rod 143, and the third connecting rod 144 are all multi-hole structures, which simplifies the forming process and facilitates manufacturing. Of course, the first connecting rod 142, the second connecting rod 143, and the third connecting rod 144 can also adopt a similar arrangement as the active rod 141, with one end being a hole and the other end being a shaft; this is not a limitation.

[0105] For example, the first link 142 and the third link 144 are both integral structures. This results in a simple structure for the link assembly 14 and high assembly efficiency. The electric tail wing hinge structure 10 can form a double self-locking structure while having a smaller number of links, and its movement is simple and reliable.

[0106] Another embodiment of this application provides an electric tail wing, including a tail wing spoiler, a drive motor, and an electric tail wing hinge structure 10 according to any embodiment of this application.

[0107] The tail spoiler is connected to the side of the connecting plate 13 away from the connecting rod assembly 14, and the drive motor is powered to the end of the input shaft 12 away from the connecting rod assembly 14.

[0108] The drive motor is used to provide rotational driving force for the input shaft 12. The drive motor drives the input shaft 12 to rotate by a certain angle or Hall effect value to control the opening or closing of the tail spoiler.

[0109] The rear spoiler can be installed on the vehicle's trunk lid. When the spoiler is open, the drive motor drives the input shaft 12 to rotate, thereby moving the connecting rod assembly 14 and the connecting plate 13, causing the spoiler to rise and form a duckbill-like protrusion on the trunk lid. This increases vehicle stability, helps reduce air resistance, saves energy, and also serves a decorative purpose, enhancing the vehicle's appearance. When the spoiler needs to be closed, the drive motor drives the input shaft 12 to rotate in the opposite direction, thereby moving the connecting rod assembly 14 and the connecting plate 13, causing the spoiler to descend and embed itself into the trunk lid.

[0110] The drive motor can be directly connected to the input shaft 12 or indirectly connected to the input shaft 12 through an intermediate structure; there is no restriction on this.

[0111] The type of drive motor can be a stepper motor, a servo motor, etc., and there are no restrictions here.

[0112] Understandably, there can be two electric tail wing hinge structures 10, in order to further increase the stability of the tail wing spoiler during movement.

[0113] Another embodiment of this application provides a vehicle, including a vehicle body and an electric tail wing according to any embodiment of this application, wherein the fixed seat 11 is connected to the vehicle body.

[0114] The vehicle body can provide stable support for the fixed seat 11, thereby increasing the reliability of the rear spoiler's movement.

[0115] It should be noted that the vehicle in this application can be of various types, such as sedan, commercial vehicle, SUV or SUV.
