For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0034] Unless otherwise specified, the front-to-back direction in this application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0035] Reference below Figure 1-Figure 5 A spoiler assembly 100 according to an embodiment of the present invention is described. The two spoiler panels 1 of the spoiler assembly 100 are movably connected to the vehicle body via a movable mechanism 2. When a downward force is applied to the two spoiler panels 1, the ends of the two spoiler panels 1 away from each other are adapted to swing upward, so that the two spoiler panels 1 present a V-shaped structure. Air is concentrated at the position of the V-shaped structure formed by the two spoiler panels 1, thereby generating greater air downforce and increasing the adhesion between the wheels and the ground. In addition, the overall structure of the spoiler assembly 100 is compact, and the number of parts is less than that of other spoiler assemblies 100, making it easy to process, produce and assemble.

[0036] like Figure 1-5 As shown, a spoiler assembly 100 according to one embodiment of the present invention includes: two spoiler panels 1, which are distributed in the transverse direction of the vehicle, and each spoiler panel 1 is connected to the vehicle body via a set of movable mechanisms 2; wherein the two sets of movable mechanisms 2 are suitable for driving the corresponding spoiler panels 1 to move relative to the vehicle body, and causing the ends of the two spoiler panels 1 facing away from each other to swing upward or downward.

[0037] In practice, the rear wing panel 1 is provided at the rear of the vehicle body and is raised relative to the vehicle body. When the vehicle is moving forward, the main function of the rear wing panel 1 is to reduce the lift at the rear of the vehicle, thereby improving the stability and handling of the vehicle.

[0038] The embodiment of the present invention is provided with two tail wing panels 1, and both tail wing panels 1 are connected to the vehicle body through a set of movable mechanisms 2, wherein the two tail wing panels 1 are horizontal and flush in an initial state. During the initial movement, the electric spring, pneumatic spring or balance spring exerts force on the two tail wing panels 1 through a telescopic action, and the movable mechanism 2 can ensure that the tail wing panels 1 rotate smoothly relative to the vehicle body. For example, when the electric spring is compressed, the ends of the two tail wing panels 1 close to each other can rotate downward at the same time, and the two tail wing panels 1 rotate at the ends close to each other to be lower than the ends away from each other, that is, the ends away from each other rotate upward, so that the two tail wing panels 1 present a V-shaped structure, and the V-shaped structure forms a space open upward. Then, during the driving of the vehicle, the airflow can be gathered in the upward-open space of the V-shaped structure formed by the two tail wing panels 1, that is, the pressure of the airflow at the position where the two tail wing panels 1 are close to each other is greater than the pressure away from each other, thereby improving the ground force between the wheels and the ground, thereby increasing the stability of the vehicle driving.

[0039] If the two rear wing panels 1 are of the same size and the ends of the two rear wing panels 1 that are closer to each other are located in the middle position of the vehicle in the transverse direction, then when the pressure of the airflow on the ends of the two rear wing panels 1 that are closer to each other is greater than the pressure on the ends that are farther away from each other, it is equivalent to the airflow pressure on the middle position of the rear wing panels 1 being greater, that is, it is equivalent to the pressure on the middle position of the wheels on both sides being greater, thereby improving the ground contact force between the wheels and the ground and, at the same time, improving the force balance.

[0040] When the tail wing panels 1 are not in use, the electric spring, pneumatic spring or balance spring exerts force on the two tail wing panels 1 through telescopic action. When the electric spring is reset, the two tail wing panels 1 can be rotated toward each other's ends until they are reset.

[0041] Therefore, the rear wing assembly 100 according to the embodiment of the present invention can generate greater air downforce, thereby improving the adhesion between the wheels and the ground, thereby improving the driving stability of the vehicle.

[0042] In some embodiments, the movable mechanism 2 includes a first rotating component 21 and a second rotating component 22; one end of each tail wing panel 1 is fixedly connected to a swing arm 211, and the swing arm 211 is movably connected to the first rotating component 21 and the second rotating component 22 respectively. The first rotating component 21 and the second rotating component 22 are both movably connected to the vehicle body. When the tail wing panel 1 is suitable for rotation, the first rotating component 21 enables the tail wing panel 1 to rotate in the up and down directions, and the second rotating component 22 guides the rotation trajectory of the tail wing panel 1.

[0043] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the swing arm 211 is provided with a mounting groove 219, which is open toward the outside in the vehicle width direction, and the first rotating assembly 21 is installed at the mounting groove 219. The swing arm 211 is rotatably connected to the vehicle body through the first rotating assembly 21, and a first mounting portion 217 and a second mounting portion 218 can be provided at a position downward of the swing arm 211. The first mounting portion 217 and the second mounting portion 218 are each used to install an electric spring or a pneumatic spring. The first mounting portion 217 and the second mounting portion 218 are both ball pin mounting seats, such as the first mounting portion 217 and the second mounting portion When each part 218 is equipped with an electric spring, the electric spring is driven by a motor to drive the swing arm 211 to move downward, and the swing arm 211 and the tail wing panel 1 are fixedly connected, one end of the first rotating component 21 is movably connected to the swing arm 211, and the other end of the first rotating component 21 is rotatably connected to the vehicle body. When the swing arm 211 moves downward, it drives the tail wing panel 1 to move downward, so that under the action of the first rotating component 21, the tail wing panel 1 is rotated relative to the vehicle body, then the ends of the two tail wing panels 1 away from each other rotate upward, and the ends close to each other rotate downward.

[0044] At the same time, the swing arm 211 is also connected to a second rotating component 22, which is rotationally connected to the swing arm 211 and to the vehicle body. By setting the second rotating component 22 and the first rotating component 21, the different positions of the swing arm 211 are kept rotationally connected to the vehicle body, thereby improving the stability of the rear wing panel 1 and avoiding shaking and deformation of the rear wing panel 1 due to excessive airflow pressure. When the rear wing panels 1 rotate downward at one end close to each other, the second rotating component 22 can serve as a force point rotationally connected to the vehicle body, thereby improving the stability of the rear wing panel 1, and can also guide the rear wing panel 1 when it rotates.

[0045] In some embodiments, the first rotating assembly 21 includes a movable shaft arm 212, a first rotating shaft 215 and a second rotating shaft 214, one end of the movable shaft arm 212 is rotationally connected to the swing arm 211 through the first rotating shaft 215, and the other end of the movable shaft arm 212 is rotationally connected to the vehicle body through the second rotating shaft 214.

[0046] Reference Figure 2 As shown, the movable shaft arm 212 extends into the mounting slot 219 of the swing arm 211, and one end is rotatably connected to the swing arm 211 through the first rotating shaft 215, and the other end is rotatably connected to the vehicle body through the second rotating shaft 214. When the swing arm 211 rotates downward under the drive of the electric spring, as shown in FIG. Figure 5 As shown, the swing arm 211 applies an upward force to the right side of the movable shaft arm 212, causing the right side of the movable shaft arm 212 to rotate upward and the left side to rotate downward. The right side of the movable shaft arm 212 is the rotation connection of the first rotation shaft 215, and the left side of the movable shaft arm 212 is the rotation connection of the second rotation shaft 214. Through the setting of the movable shaft arm 212, when the swing arm 211 drives the tail wing plate 1 to rotate, the movable shaft arm 212 moves, so that the tail wing plate 1 can be smoothly driven to rotate downward.

[0047] In some embodiments, the axial centerline of the first rotating shaft 215 is parallel to the longitudinal centerline of the vehicle, and the axial centerline of the second rotating shaft 214 is inclined along the front-rear direction of the vehicle and intersects the axial centerline of the first rotating shaft 215 .

[0048] In practice, refer to Figure 2As shown, the dynamic shaft arm 212 can be divided into an integrally formed first section and a second section. The first section is parallel to the width direction of the vehicle, and the second section is inclined toward the rear side of the vehicle relative to the first section. The first section is connected to the first rotating shaft 215, and the second section is connected to the second rotating shaft 214, so that the first rotating shaft 215 at one end of the dynamic shaft arm 212 can be set to extend along the longitudinal center line of the vehicle, and the second rotating shaft 214 intersects with the first rotating shaft 215. That is, through the cooperation relationship between the first rotating shaft 215 and the second rotating shaft 214, the rear wing panel 1 can rotate downward along a predetermined trajectory when rotating, and facilitates the rotational connection between the second rotating shaft 214 and the vehicle body, thereby realizing a reasonable position layout.

[0049] In some embodiments, the movable shaft arm 212 is adapted to slide axially relative to the first rotating shaft 215 when rotating relative to the first rotating shaft 215 , and is adapted to slide axially relative to the second rotating shaft 214 when rotating relative to the second rotating shaft 214 .

[0050] That is to say, when the tail wing panel 1 rotates downward under the drive of the swing arm 211, the movable shaft arm 212 rotates, and the position of the movable shaft arm 212 changes. When the movable shaft arm 212 can also move slightly axially along the first rotation axis 215 and the second rotation axis 214, the flexibility of the rotation of the movable shaft arm 212 can be improved, thereby improving the flexibility of the two tail wing panels 1 to rotate downward at one end close to each other.

[0051] In some embodiments, the second rotating shaft 214 is rotatably connected to the first mounting base 213 , and the first mounting base 213 is fixedly connected to the vehicle body.

[0052] Among them, the first mounting base 213 is fixedly connected to the vehicle body, the dynamic shaft arm 212 is fixedly connected to the second rotating shaft 214, and the second rotating shaft 214 is rotatably connected to the first mounting base 213, that is, the rotational connection between the dynamic shaft arm 212 and the vehicle body is realized through the first mounting base 213 and the second rotating shaft 214. The first mounting base 213 provides a connection position between the dynamic shaft arm 212 and the vehicle body, and strengthens the strength of the connection between the dynamic shaft arm 212 and the vehicle body, and enables the dynamic shaft arm 212 to move relative to the vehicle body when rotating.

[0053] In some embodiments, the second rotating assembly 22 includes a first guide ball head 221 and a ball head mounting seat 223; the first guide ball head 221 is rotatably connected to the swing arm 211, the first guide ball head 221 is fixedly connected to the ball head mounting seat 223, and the ball head mounting seat 223 is rotatably connected to the vehicle body.

[0054] Reference Figure 3As shown, the first guide ball head 221 of the second rotating component 22 and the swing arm 211 are rotatably connected, which can improve the connection flexibility between the swing arm 211 and the first guide ball head 221, that is, when the swing arm 211 moves downward, it drives the tail wing panel 1 to rotate downward, and the direction of the tail wing panel 1 is constantly changing. The action of the first guide ball head 221 adapts to the change in the direction of the tail wing panel 1. At the same time, the first guide ball head 221 is also rotatably connected to the vehicle body through the ball head mounting seat 223, that is, the second rotating component 22 can serve as another installation position for the active connection between the tail wing panel 1 and the vehicle body, so that the tail wing panel 1 can always maintain an active connection with the vehicle body during the rotation and change of direction, so that there is a force point between the tail wing panel 1 and the vehicle body, and at the same time it can also improve the flexibility of the tail wing panel 1 when rotating.

[0055] In addition, the first rotating shaft 215 can be arranged between the second rotating shaft 214 and the first guide ball head 221, so that the rotation of the three positions does not interfere with each other, and when the swing arm 211 drives the tail wing panel 1 to rotate downward, while the dynamic shaft rotating arm 212 rotates, the first rotating shaft 215, the second rotating shaft 214 and the first guide ball head 221 rotate relative to the swing arm 211 more smoothly.

[0056] It should be noted that, in actual design, when the axes of the first rotating shaft 215 and the second rotating shaft 214 at both ends of the movable shaft rotating arm 212 intersect at one point, the axes of the first rotating shaft 215 and the second rotating shaft 214 are extended to form an axis intersection point, and the axis intersection point may intersect or not intersect with the center of the ball head at the rotation connection between the first guide ball head 221 and the swing arm 211. When the center of the ball head at the rotation connection between the first guide ball head 221 and the swing arm 211, the first rotating shaft 215 and the second rotating shaft 214 are intersected, the first rotating shaft 215 and the second rotating shaft 214 are intersected. When the axes intersect, the displacement of the movable shaft arm 212 along the axial movement of the first rotating shaft 215 and the second rotating shaft 214 is 0; when the ball head center of the first guide ball head 221 does not intersect with the intersection point of the axes of the first rotating shaft 215 and the second rotating shaft 214, the farther the distance between the ball head center of the first guide ball head 221 and the intersection point of the axes of the first rotating shaft 215 and the second rotating shaft 214 is, the greater the displacement of the movable shaft arm 212 along the axial movement of the first rotating shaft 215 and the second rotating shaft 214 is.

[0057] In some embodiments, the tail assembly 100 further includes a third rotating shaft 222 , through which the ball head mounting seat 223 is rotatably connected to the vehicle body, and a central axis of the third rotating shaft 222 extends along the width direction of the vehicle.

[0058] For details, please refer to Figure 3As shown, the ball head mounting seat 223 includes a connected transverse mounting portion 2232 and a vertical mounting portion 2231, the first guide ball head 221 passes through the transverse mounting portion 2232 from top to bottom and is fixedly connected to the transverse mounting portion 2232, and the vertical mounting portion 2231 is rotatably connected to the vehicle body through the third rotating shaft 222. That is, when the swing arm 211 moves downward, the first guide ball head 221 rotates relative to the swing arm 211 to adapt to the movement of the swing arm 211. At the same time, the third rotating shaft 222 enables the first guide ball head 221 and the ball head mounting seat 223 to rotate relative to the vehicle body. That is, when the swing arm 211 and the rear wing panel 1 rotate, they are always movably connected to the vehicle body and rotate relative to the vehicle body, and the movement trajectory is controllable. By setting the rotational connection between the first guide ball head 221 and the swing arm 211, and the rotational connection between the first guide ball head 221 and the vehicle body by the third rotating shaft 222, the flexibility of the rear wing panel 1 in moving downward can be improved, and the phenomenon of getting stuck can be avoided.

[0059] In some embodiments, the third rotating shaft 222 is rotatably connected to the ball head mounting seat 223 and fixedly connected to the second mounting base 224 . The second mounting base 224 is fixedly connected to the vehicle body.

[0060] In practice, the third rotating shaft 222 is fixedly connected to the second mounting base 224 and is rotatably connected to the ball head mounting seat 223. The second mounting base 224 is fixedly connected to the vehicle body. By setting the second mounting base 224, the connection direction and connection position between the third rotating shaft 222 and the vehicle body can be changed, and when the first guide ball head 221 rotates relative to the swing arm 211, it can also rotate relative to the third rotating shaft 222, that is, rotate relative to the vehicle body, so the connection flexibility is higher, the rotation flexibility is high, and the rotation is smoother.

[0061] In some embodiments, the first guide ball head 221 includes a first rod body portion 2211 and a first ball head portion 2212 connected to each other. The first rod body portion 2211 is fixedly connected to the ball head mounting seat 223, and the first ball head portion 2212 is rotatably connected to the swing arm 211 through the first ball cap 216.

[0062] Specifically, a first ball cap 216 is provided on the rear side of the swing arm 211, and the first ball head portion 2212 is inserted into the first ball cap 216. When the swing arm 211 and the rear wing panel 1 rotate downward, the first ball cap 216 and the first ball head portion 2212 rotate relative to each other, thereby adapting to the state in which the ends of the two rear wing panels 1 close to each other move downward. That is, as the rear wing panel 1 gradually rotates downward, the swing arm 211 drives the relative position between the first ball cap 216 and the first ball head portion 2212 to change, but the first rod body portion 2211 is always along the up and down direction of the vehicle.

[0063] Therefore, the tail wing panel 1 can not only rotate, but also use the first guide ball head 221 as a rotation support point, and the first guide ball head 221 and the ball head mounting seat 223 are rotationally connected to the vehicle body, which is equivalent to the rear side of the swing arm 211 maintaining rotational support with the vehicle body through the first ball cap 216, the first guide ball head 221, the ball head mounting seat 223, the third rotating shaft 222 and the second mounting base 224, thereby improving the stability of the rotation support of the tail wing panel 1.

[0064] Moreover, the position of the second mounting base 224 is lower than that of the first mounting base 213, and the second mounting base 224 at the bottom of each tail wing panel 1 is closer to the other tail wing panel 1 than the first mounting base 213. The first mounting base 213 serves as the position where the dynamic shaft arm 212 is rotatably connected to the vehicle body, and the second mounting base 224 serves as the position where the other end of the swing arm 211 is rotatably connected to the vehicle body. After the tail wing panel 1 rotates, the ends of the two tail wing panels 1 close to each other are lower than the ends away from each other. Then, the height of the second mounting base 224 of the tail wing panel 1 is lower than the height of the first mounting base 213, thereby adapting to the rotation trajectory of the tail wing panel 1. That is, by setting different positions of the rotation connection between the tail wing panel 1 and the vehicle body, the final rotation trajectory of the tail wing panel 1 is limited, so that the two tail wing panels 1 can move to present a V-shaped structure.

[0065] In some embodiments, the tail assembly 100 further includes a connection mechanism 3 , which enables the ends of the two tail panels 1 close to each other to be movably connected.

[0066] In practice, the connecting mechanism 3 movably connects the two tail wing panels 1, that is, when the tail wing panel 1 at one end rotates under the action of a set of movable mechanisms 2, the tail wing panel 1 at the other end rotates under the action of another set of movable mechanisms 2, which can realize the flexible rotation of the two tail wing panels 1 while movably connecting the two tail wing panels 1 to avoid the rotation angle difference between the two tail wing panels 1 being too large, making it difficult to form the set V-shaped structure, that is, maintaining the synchronization and stability of the movement of the two tail wing panels 1.

[0067] In some embodiments, the connecting mechanism 3 includes two connecting frames 31 and a fourth rotating shaft 32. The central axis of the fourth rotating shaft 32 extends along the up and down direction of the vehicle. The two connecting frames 31 are rotatably connected to the fourth rotating shaft 32. Each connecting frame 31 is rotatably connected to a tail wing panel 1.

[0068] Combine Figure 2 and Figure 3As shown, each connecting frame 31 is constructed as an L-shaped structure, one end of the L-shaped structure is rotationally connected to the fourth rotating shaft 32, and the other end is rotationally connected to the tail wing panel 1. Then, when the tail wing panel 1 on one side rotates downward, the position of the fourth rotating shaft 32 is lowered along the height direction of the vehicle, so that the tail wing panel 1 on the other side can also move downward. Of course, the tail wing panel 1 on the other side also has a corresponding electric spring to drive the swing arm 211 to move downward, thereby achieving the same movement trajectory of the two tail wing panels 1, making the two tail wing panels 1 present a V-shaped structure, thereby increasing the downward pressure of the airflow, and making the pressure at the position where the two tail wing panels 1 are close to each other greater than at the position where they are far away from each other, thereby improving the ground force of the vehicle.

[0069] In some embodiments, a second guide ball head 33 is provided on the lower side of each tail wing panel 1 , and a second ball cap 311 corresponding to the second guide ball head 33 is provided on the connecting frame 31 , and the second guide ball head 33 is rotatably connected to the second ball cap 311 .

[0070] That is, reference Figure 3 As shown, the second guide ball head 33 includes a second ball head portion 331, and the second ball head portion 331 is rotatably connected to the second ball cap 311 of the connecting frame 31. Then, when the tail wing plate 1 rotates, the second ball head portion 331 can rotate freely in the second ball cap 311, thereby realizing a V-shaped distribution of the two tail wing plates 1. In addition, the connection method of the second guide ball head 33 and the second ball cap 311 makes the rotation flexibility of the tail wing plate 1 higher.

[0071] It should be noted that, in the tail assembly 100 of the embodiment of the present invention, the tail panel 1 has a unique motion trajectory, and the entire mechanism is a single-degree-of-freedom mechanism, which reduces the influence of other factors that cause changes in the trajectory path and has good motion stability; the movable mechanism 2 of the tail assembly 100 is set to a hinge movable principle, with a compact structure and fewer parts than other tail hinges, and is easy to process, produce and assemble. The movable mechanism 2 can take into account and ensure the rapid opening and closing of the tail panel 1.

[0072] In the embodiment of the present invention, it can be considered that the movable mechanism 2 is composed of two transmission hinge mechanisms and one connecting hinge mechanism, and the tail wing transmission hinge mechanism is composed of two cylindrical pairs, one spherical pair and one rotation pair. The first rotating shaft 215 and the second rotating shaft 214 serve as cylindrical pairs, the first ball head 2212 serves as a spherical pair, and the axis of the third rotating shaft 222 serves as a rotation pair.

[0073] Among them, the connecting mechanism 3 is composed of two spherical pairs and a revolute pair, the two second ball heads 331 serve as spherical pairs, and the axis of the fourth rotating shaft 32 serves as a revolute pair; the first guide ball head 221 and the ball head mounting seat 223 and other components play the role of guiding the hinge motion trajectory, and the dynamic shaft arm 212 and the swing arm 221 connecting the tail wing panel 1 mainly play the role of preventing the door from sinking and bearing weight; when the left tail wing panel 1 is in motion, the right end of the left tail wing panel 1 moves downward and the left end moves upward, that is, it presents an arc-shaped motion trajectory, that is, the cosine state equation motion trajectory, the right end of the right tail wing panel 1 moves upward and the left end moves downward, and finally forms an open state, realizing a combined motion action of first opening sideways and then rotating upward. When the tail wing panel 1 is closed, the action is opposite to the above-mentioned tail wing opening.

[0074] An embodiment of the present invention also discloses a vehicle, including the above-mentioned tail wing assembly 100, wherein the two tail wing panels 1 of the tail wing assembly 100 are movably connected to the vehicle body, and when the ends of the two tail wing panels 1 facing away from each other are swung upward, the two tail wing panels 1 present a V-shaped structure, so that air is concentrated at the position of the V-shaped structure formed by the two tail wing panels 1, thereby generating greater air downforce, increasing the adhesion between the wheels and the ground, and improving the stability of the vehicle's driving.
