[0064] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0065] The tail wing 1 is arranged at the rear of the vehicle. The main function of the tail wing 1 is to rotate and open and close at different angles through the power drive of the motor 21 during the driving process of the vehicle, thereby changing the direction of the airflow on the roof, providing different degrees of downforce for the vehicle, and improving the stability and handling performance of the vehicle. When the vehicle is driving at a low speed, the tail wing 1 is folded to reduce wind resistance and fuel consumption; as the vehicle speed increases, the tail wing 1 gradually rises to improve the aerodynamic performance of the vehicle, enhance the handling and high-speed driving safety.

[0066] like Figures 1 to 18 As shown, a rear wing 1 provided by an embodiment of the utility model includes a first panel 11, a second panel 12 and a support portion 13. The first panel 11 and the second panel 12 are arranged opposite to each other, and the second panel 12 is located below the first panel 11 in the height direction of the vehicle, and the second panel 12 faces the vehicle body 6.

[0067] The first plate 11 includes a plate body 111 , a first connecting member 112 and a second connecting member 113 . The plate body 111 connects one end of the first connecting member 112 and one end of the second connecting member 113 . The second plate 12 connects the other end of the first connecting member 112 and the other end of the second connecting member 113 .

[0068] Among them, the panel body 111, the first connecting member 112 and the second connecting member 113 are an integrally formed structure, the first connecting member 112 is bent from one end of the panel body 111 to the second panel 12, and the second connecting member 113 is bent from the other end of the panel body 111 to the second panel 12. In the front and rear direction of the vehicle, the front end of the second panel 12 is connected to the second connecting member 113, and the rear end of the second panel 12 is connected to the first connecting member 112. The second panel 12 is connected between the first connecting member 112 and the second connecting member 113, so that the outer edge of the first panel 11 is connected to the outer edge of the second panel 12.

[0069] In this embodiment, the first plate 11 and the second plate 12 are connected to form a whole through the first connecting member 112 and the second connecting member 113, so that the tail wing 1 forms a double-layer structure. While ensuring lightness, the strength of the tail wing 1 can be enhanced, and the wind pressure that can be borne is greater. During the process of unfolding or closing the tail wing 1, it is less likely to vibrate, thereby reducing noise.

[0070] In one embodiment, the first plate 11 and the second plate 12 are non-metallic parts, which can meet the lightweight requirement of the tail wing 1 .

[0071] In one embodiment, the middle portion of the panel body 111 is arched toward the second panel 12, so that the outer surface of the rear wing 1 forms a structure that is slightly lower in the middle and slightly higher at both ends, thereby affecting the flow rate of the airflow when the rear wing 1 changes the direction of the airflow, thereby increasing the downforce of the vehicle.

[0072] In one embodiment, the first connecting member 112 is arc-shaped, and the first connecting member 112 arches in a direction away from the plate body 111 , so that when the tail wing 1 is deployed, the airflow flows more smoothly when passing through the first connecting member 112 .

[0073] In one embodiment, a transfer member 1131 is installed on the second connecting member 113 , and the transfer member 1131 is fixedly connected to the second plate member 12 , so that one end of the second plate member 12 and one end of the first plate member 11 are connected via the transfer member 1131 .

[0074] Preferably, the adapter 1131 is a reed nut, and a screw hole is provided on the second plate 12. The screw passes through the screw hole and is connected to the reed nut, thereby fixing the adapter 1131 and one end of the second plate 12.

[0075] In one embodiment, the tail 1 further includes a support portion 13, which is disposed on the second plate 12 and supports the first plate 11. The first plate 11 and the second plate 12 can enclose a cavity, and the support portion 13 is disposed in the cavity to support the plate body 111 to prevent deformation from affecting the direction of airflow.

[0076] The support portion 13 is supported between the first plate 11 and the second plate 12 , so that deformation of the first plate 11 and the second plate 12 can be reduced, and the strength of the tail 1 can be further increased.

[0077] The support portion 13 and the second plate 12 are integrally formed. When the first plate 11 and the second plate 12 are connected, the support portion 13 can abut against the first plate 11 to provide support. The contact portion between the support portion 13 and the first plate 11 can be bonded by applying adhesive or by welding.

[0078] In one embodiment, the support portion 13 includes a first support member 131 and a second support member 132. The first support member 131 connects the plate body 111 and the second plate 12, and can support the plate body 111. The second support member 132 connects the plate body 111 and the first connecting member 112, and can support the plate body 111 and the bent first connecting member 112.

[0079] There are multiple first support members 131 , and the multiple first support members 131 are spaced between the plate body 111 and the second plate 12 , so that the plate body 111 is subjected to a more uniform force.

[0080] In one embodiment, the first support member 131 is in an inverted L-shape, and the first support member 131 has a vertical section and a horizontal section. The vertical section is connected to the second plate 12, and the horizontal section is connected to the vertical section. An adhesive is applied to a surface of the horizontal section close to the plate body 111 to bond the first support member 131 and the plate body 111, or the horizontal section and the plate body 111 are welded.

[0081] The second support member 132 is in a "X" shape and is connected to the outer edge of the second plate member 12. When the second plate member 12 is matched with the first plate member 11, the second support member 132 is located between the plate member body 111 and the first connecting member 112. There is one bonding point or welding point between the second support member 132 and the plate member body 111, and there are two bonding points or welding points between the second support member 132 and the first connecting member 112.

[0082] In one embodiment, the rear wing 1 further includes a plurality of pads 14, which are mounted on the second plate 12 and are used to control the height of the rear wing 1 relative to the vehicle body. The pads 14 are fixed to the second plate 12 by screws, and the height of the pads 14 can be adjusted by rotating the screws, thereby controlling the clearance surface fit between the rear wing 1 and the vehicle body sheet metal, so that the rear wing 1 as a whole does not protrude from the vehicle body, thereby improving the overall appearance quality of the vehicle body.

[0083] In one embodiment, the cushion block 14 is made of rubber material. In addition to controlling the height of the tail wing 1 , the cushion block 14 can also play a buffering role to prevent the tail wing 1 from colliding during the process of unfolding or closing the tail wing 1 .

[0084] On the other hand, an embodiment of the utility model provides a tail assembly, including a drive mechanism and a tail 1 as described above, wherein the drive mechanism is suitable for being installed on a vehicle body 6, and an output end of the drive mechanism is connected to a second plate 12 to drive the tail 1 to open or close.

[0085] The driving mechanism provides power for the tail 1. Under the action of the driving mechanism, the tail 1 can rise or fall at different angles. When the tail 1 rotates a certain angle and rises, the tail 1 is in an open state. When the tail 1 rotates a certain angle and falls, the tail 1 is in a closed state.

[0086] In one embodiment, the maximum rotation angle of the rear wing 1 during the ascent or descent process can reach 20.84°. Different opening angles can be set according to different operating conditions and performance requirements of the vehicle to provide different grips for the vehicle, with a wider range of applications and higher flexibility.

[0087] In one embodiment, the driving mechanism includes a driving member 2 and a transmission mechanism 3. The transmission mechanism 3 includes a mounting seat 31, a tail wing mounting plate 32 and a connecting rod assembly 33, wherein the mounting seat 31 is connected to the vehicle body, the tail wing mounting plate 32 is connected to the second plate member 12, and the connecting rod assembly 33 is connected between the mounting seat 31 and the tail wing mounting plate 32.

[0088] The output end of the driving member 2 is connected to the connecting rod assembly 33, so that the connecting rod assembly 33 can drive the tail 1 to open or close through the tail mounting plate 32. The connecting rod assembly 33 is connected to the vehicle body through the mounting seat 31, and the connecting rod assembly 33 is connected to the tail 1 through the tail mounting plate 32. Driven by the driving member 2, the connecting rod assembly 33 can drive the tail mounting plate 32 and the tail 1 to rise or fall relative to the vehicle body, thereby presenting an open or closed state.

[0089] The driving member 2 can drive the connecting rod assembly 33 to be in a folded state or an unfolded state. When the driving member 2 drives the connecting rod assembly 33 to unfold, the connecting rod assembly 33 can drive the tail wing mounting plate 32 and the tail wing 1 to rise, so that the tail wing 1 is in an unfolded state. When the driving member 2 drives the connecting rod assembly 33 to fold, the connecting rod assembly 33 can drive the tail wing mounting plate 32 and the tail wing 1 to descend, so that the tail wing 1 is in a closed state.

[0090] In one embodiment, a first buffer member 3121 is provided on the mounting seat 31. The first buffer member 3121 is provided on a side of the mounting seat 31 close to the tail wing mounting plate 32. When the tail 1 is closed, the first buffer member 3121 abuts against the tail wing mounting plate 32 to prevent a hard collision between the tail wing mounting plate 32 and the mounting seat 31, thereby limiting and buffering the tail wing mounting plate 32.

[0091] The first buffer member 3121 is made of materials such as rubber and has a certain deformation capacity to achieve buffering.

[0092] In one embodiment, the mounting base 31 includes a base plate 311 , a first mounting plate 312 and a second mounting plate 313 . The first mounting plate 312 and the second mounting plate 313 are connected to the base plate 311 , and the first mounting plate 312 and the second mounting plate 313 are arranged opposite to each other on the base plate 311 .

One side of the third mounting plate 321 is connected to the fourth mounting plate 322 , and the other side of the third mounting plate 321 extends from the fourth mounting plate 322 toward the mounting seat 31 .

[0094] The first buffer member 3121 is mounted on the first mounting plate 312 . When the tail 1 is closed, the first buffer member 3121 abuts against the fourth mounting plate 322 to prevent the fourth mounting plate 322 from colliding with the mounting seat 31 .

[0095] In one embodiment, a second buffer 3221 is provided on the tail wing mounting plate 32, and the second buffer 3221 abuts against the second plate 12 of the tail wing 1. In this way, during the process of unfolding or closing the tail wing 1, it can effectively limit the position of the tail wing 1 and provide soft contact, thereby avoiding hard contact between the second plate 12 and the tail wing mounting plate 32 to generate friction and abnormal noise, and preventing collision between the second plate 12 and the tail wing mounting plate 32.

[0096] The second buffer member 3221 is made of materials such as rubber and has a certain deformation capacity to achieve buffering.

[0097] In one embodiment, the second buffer member 3221 is installed on the fourth mounting plate 322 . A plurality of second buffer members 3221 are provided, and the plurality of second buffer members 3221 are spaced apart on the fourth mounting plate 322 to ensure that the tail wing mounting plate 32 does not collide with the second plate member 12 .

[0098] Preferably, two second buffer members 3221 are provided.

[0099] In one embodiment, a plurality of first mounting holes 121 are provided on the second plate 12, and a plurality of second mounting holes 3222 are provided on the tail mounting plate 32, and each second mounting hole 3222 is connected to the corresponding first mounting hole 121. The second mounting holes 3222 are provided on the fourth mounting plate 322, and nuts are embedded in the first mounting holes 121. The tail mounting plate 32 can be fixed on the second plate 12 by bolts passing through the second mounting holes 3222 and connected to the embedded nuts, thereby realizing the connection between the transmission mechanism 3 and the tail 1, and when the driving member 2 drives the transmission mechanism 3 to move, the tail 1 can be driven to move up and down.

[0100] In a preferred embodiment, three first mounting holes 121 are provided, the number of second mounting holes 3222 is consistent with the number of first mounting holes 121, and the three first mounting holes 121 are arranged in a triangular shape, which can increase the connection stability and firmness between the tail wing mounting plate 32 and the tail wing 1, thereby increasing the connection strength of the tail wing 1.

[0101] In one embodiment, the connecting rod assembly 33 includes a first connecting rod 331, a second connecting rod 332 and a third connecting rod 333. One end of the first connecting rod 331 is connected to the output end of the driving member 2, the second connecting rod 332 is connected to the other end of the first connecting rod 331 and the third connecting rod 333, and the two ends of the third connecting rod 333 are respectively connected to the tail mounting plate 32 and the mounting seat 31. The driving member 2 can drive the first connecting rod 331 to rotate, thereby driving the second connecting rod 332 and the third connecting rod 333 to rotate. When the tail 1 is opened to the maximum angle, the first connecting rod 331 and the second connecting rod 332 extend in opposite directions from the intersection. The second link 332 is located on the extension line of the first link 331, and the total length of the first link 331 and the second link 332 reaches the maximum. At this time, the first link 331 and the second link 332 are in a straight line, and a mechanical self-locking state is formed between the first link 331 and the second link 332. It is not easy for the state of the first link 331 and the second link 332 to change, so that the tail 1 can maintain an open state.

[0102] When the tail 1 is closed, the first link 331 and the second link 332 partially overlap. At this time, the first link 331 and the second link 332 extend from the intersection in the same direction, so that the first link 331 and the second link 332 overlap, the total length of the first link 331 and the second link 332 is minimized, and a self-locking state is formed between the first link 331 and the second link 332. The state change between the first link 331 and the second link 332 is not easy to occur, so that the tail 1 can remain in the closed state. Driven by the driving member 2, the tail 1 can switch between the open state and the closed state.

[0103] In this embodiment, the length of the first connecting rod 331 is smaller than the length of the second connecting rod 332 , and the length of the overlapping portion of the first connecting rod 331 and the second connecting rod 332 is equal to the length of the first connecting rod 331 .

[0104] As an example, the connecting rod assembly 33 includes a first connecting rod 331, a second connecting rod 332 and a third connecting rod 333. One end of the first connecting rod 331 is connected to the output end of the driving member 2, and the driving member 2 can drive the first connecting rod 331 to rotate.
