[0095] When the lifting device 30 drives the base 10 to move upward in the vertical direction of the vehicle, the lifting device 30 can drive the second transmission component 42 to move through the first transmission component 41, so as to drive the first tail wing 21 and the second tail wing 22 to move away from each other, realizing the deployment of the first tail wing 21 and the second tail wing 22, which can increase the downward pressure when the vehicle is running, and is beneficial to improving the stability and handling performance of the vehicle at high speed; when the lifting device 30 drives the base 10 to move downward in the vertical direction of the vehicle, the lifting device 30 can drive the second transmission component 42 to move through the first transmission component 41, so as to drive the first tail wing 21 and the second tail wing 22 to move towards each other, realizing the closing of the first tail wing 21 and the second tail wing 22, which can reduce the wind resistance when the vehicle is running at low speed, is beneficial to saving consumption, improving the economy of the vehicle, and is convenient for parking in a limited parking space.

[0096] Compared with the fixed tail wing in the related art, the tail wing assembly 100 of the present utility model has the advantages of large expandable width, high aesthetics, etc., and can simultaneously control the rising and deployment or falling and closing of the first tail wing 21 and the second tail wing 22, making the control more convenient and beneficial to improving the user experience.

[0097] It should be noted that for the convenience of description, the orientations such as "left-right direction" in the present utility model are based on the orientation relationship shown in the drawings, rather than the limitation of the orientation in the actual application process.

[0098] In some embodiments, such as Figure 1 As Figure 2 shown, the first tail wing 21 and the second tail wing 22 are arranged in the length direction of the base 10, which can effectively increase the deployment length of the first tail wing 21 and the second tail wing 22, improve the grip of the vehicle, ensure the stability of the vehicle at high speed, and ensure the beautiful appearance.

[0099] According to the tail wing assembly 100 of the embodiment of the present utility model, the first tail wing 21 and the second tail wing 22 are movably arranged on the base 10 along the length direction of the base 10. The lifting device 30 is used to drive the base 10 to move in the up and down direction of the vehicle. The second transmission component 42 of the unfolding device 40 is connected to the first tail wing 21 and the second tail wing 22, and the first transmission component 41 of the unfolding device 40 is connected to the lifting device 30 and the second transmission component 42. When the lifting device 30 drives the base 10 to move upward in the up and down direction of the vehicle, it drives the second transmission component 42 to drive the first tail wing 21 and the second tail wing 22 to move away from each other. When the lifting device 30 drives the base 10 to move downward in the up and down direction of the vehicle, it drives the second transmission component 42 to drive the first tail wing 21 and the second tail wing 22 to move closer to each other. It can realize the control of the first tail wing 21 and the second tail wing 22, has the advantages of large expandable width, high aesthetics, etc., and can simultaneously control the rising and unfolding or the falling and closing of the first tail wing 21 and the second tail wing 22, and the control is more convenient, which is beneficial to improving the user experience.

[0100] In some embodiments of the present utility model, such as Figure 3 , Figure 4 , Figure 33 and Figure 46 shown, the lifting device 30 includes a lifting component 31 and a driving mechanism 32. The lifting component 31 includes a support seat 311, a support bracket 312 and a lifting link assembly 313.

The upper and lower ends of the lifting link assembly 313 are respectively connected to the support bracket 312 and the support seat 311. The driving mechanism 32 can drive the lifting link assembly 313 to be adjustable in height in the up and down direction, so that the lifting link assembly 313 can drive the support bracket 312 to move in the up and down direction, thereby enabling the base 10 to move in the up and down direction, realizing the control requirement for the up and down movement of the first tail wing 21 and the second tail wing 22. In addition, the structure of the lifting device 30 is simple and the control is convenient, which is beneficial to reducing the production cost. Moreover, the lifting link assembly 313 is connected to the first transmission component 41. When the lifting link assembly 313 is adjustable in height in the up and down direction, it is convenient to control the movement of the first tail wing 21 and the second tail wing 22 through the first transmission component 41, making the control more convenient.

[0101] According to some embodiments of the present utility model, such as Figure 4 , Figures 7 - 10 , Figures 13 - 15 , Figures 18 - 20 , Figure 43 and Figure 44As shown, the lifting link assembly 313 includes a first lifting link 51 and a second lifting link 52.

The lower end of the second lifting link 52 is rotatably connected to the support base 311, and the upper end of the second lifting link 52 is rotatably connected to the support bracket 312. The drive mechanism 32 can drive the first lifting link 51 and the second lifting link 52 to rotate relative to the support base 311.

[0102] Thus, by driving the first lifting link 51 and the second lifting link 52 by the drive mechanism 32, the height of the lifting link assembly 313 can be adjusted in the up and down direction, facilitating the adjustment of the height of the lifting link assembly 313. Moreover, the first lifting link 51 and the second lifting link 52 can enhance the stability and load-bearing capacity of the lifting device 30, making the lifting process smoother.

The driven wheel 325 meshes with the driving wheel 324. The driving wheel 324 is fixedly arranged on the motor shaft 322. The lower end of the second lifting link 52 is connected to the driven wheel 325. Thus, when the motor shaft 322 rotates, the motor shaft 322 can drive the driving wheel 324 to rotate relative to the support base 311. The driving wheel 324 meshes with the driven wheel 325 to drive the driven wheel 325 to rotate. The lower end of the second lifting link 52 rotates synchronously with the driven wheel 325, so that the second lifting link 52 rotates relative to the support base 311, realizing the height adjustment of the second lifting link 52.

[0105] Thus, the gear assembly 323 facilitates the synchronous movement of the first lifting link 51 and the second lifting link 52, avoiding problems such as dislocation, making the movement more reliable. Moreover, the gear assembly 323 can improve the transmission efficiency and reduce energy loss. At the same time, the first lifting link 51 and the second lifting link 52 are simple to control, and the control accuracy of the motor 321 is high, which can ensure the accuracy and reliability of the lifting action.

[0106] In some embodiments, as Figure 4 、 Figure 8 shown in Figure 10 , the driving wheel 324 and the first lifting link 51 are coaxial, which can make the structure of the lifting device 30 compact, facilitating the reduction of the occupied space, and thus being beneficial to reducing the layout space requirements for the tail assembly 100.

[0107] In some embodiments, the lower end of the second lifting link 52 is connected to the driven wheel 325 through a pin shaft, making the connection between the lower end of the second lifting link 52 and the driven wheel 325 reliable, facilitating the driven wheel 325 to drive the second lifting link 52 to rotate synchronously, and the connection structure is simple, which is beneficial to reducing the production cost.

[0108] In some embodiments, as Figure 4 、 Figure 8 shown in Figure 10 、 Figure 50 shown in Figure 51 , the gear assembly 323 further includes a gear box 80. The gear box 80 includes an inner plate 81 and an outer plate 82 that are mutually covered. The driving wheel 324 and the driven wheel 325 are located between the inner plate 81 and the outer plate 82. The inner plate 81 and the outer plate 82 can protect the driving wheel 324 and the driven wheel 325, preventing the driving wheel 324 and the driven wheel 325 from being exposed and damaged, which is beneficial to extending the service life of the gear assembly 323.

[0109] According to some embodiments of the present invention, as Figures 3 - 5 、 Figures 7 - 22 shown in

[0110] , the support bracket 312 is provided with a chute 314. One end in the length direction of the first transmission assembly 41 is connected to the first lifting link 51. The upper end of the first lifting link 51 is slidably arranged in the chute 314. By sliding the first lifting link 51 in the chute 314, the first transmission assembly 41 can be driven to move along the length direction of the base 10, and through the transmission of the second transmission assembly 42, it is converted into the movement of the first tail wing 21 and the second tail wing 22 along the length direction of the base 10.Thus, only one driving mechanism 32 can be used to raise and deploy or lower and close the first tail wing 21 and the second tail wing 22, that is, to realize the actions of the first tail wing 21 and the second tail wing 22 in two directions, namely the vertical upward direction and the horizontal direction. This can simplify the movement of the first tail wing 21 and the second tail wing 22, avoid the problem of complex driving motion mechanisms in the opening and closing process of the three-segment tail wing in the related art, make the control convenient, and avoid driving the lifting device 30 and the deploying device 40 respectively by multiple driving mechanisms 32. This can reduce the number of driving mechanisms 32, facilitate the reduction of manufacturing costs, and at the same time can reduce the occupied space and the requirements for the layout space of the tail wing assembly 100.

[0111] In some embodiments, as Figure 4 , Figures 7 - 10 , Figure 14 , Figure 15 , Figure 19 , Figure 20 and Figure 45 shown, a slider 44 is provided at one end of the first transmission component 41 in the length direction. The slider 44 is rotatably connected to the first lifting link 51, so that the first transmission component 41 can be connected to the first lifting link 51 through the slider 44, ensuring a reliable connection between the first transmission component 41 and the first lifting link 51. And the slider 44 is slidably arranged in the chute 314, so that the slider 44 can drive one end of the first transmission component 41 in the length direction and the upper end of the first lifting link 51 to move relative to the length direction of the chute 314, meeting the required movement requirements. At the same time, it can reduce the structural complexity of the first lifting link 51, facilitate connection and processing and manufacturing, and is beneficial to reducing production costs.

[0112] In some embodiments, a connecting protrusion 441 is provided on the slider 44. The connecting protrusion 441 passes through the first lifting link 51, which can realize the connection between the first lifting link 51 and the slider 44, ensure a reliable connection between the first lifting link 51 and the slider 44, and has a simple structure, which can reduce production costs and improve assembly efficiency.

[0113] In some embodiments of the present invention, as Figure 3 and Figure 4 shown, there are two lifting components 31. The two lifting components 31 are arranged at intervals along the length direction of the base 10. By the two lifting components 31, the stability and balance of the first tail wing 21 and the second tail wing 22 during the lifting process can be improved, and the two lifting components 31 can work together to effectively disperse the load, and at the same time can reduce the risk of overall failure caused by the failure of a single component.

[0114] In some embodiments where the driving mechanism 32 includes a motor 321 and a gear assembly 323, as Figure 4As shown, there are two gear assemblies 323 corresponding to the lifting assemblies 31 one by one. The motor shaft 322 extends along the length direction of the base 10. Two driving wheels 324 are arranged at intervals along the length direction of the motor shaft 322, and both two driving wheels 324 are fixedly arranged on the motor shaft 322. The lower ends of two second lifting connecting rods 52 are connected to the corresponding driven wheels 325 and rotate synchronously. Thus, one motor 321 can be used to control the two lifting assemblies 31, making the control convenient and reducing the production cost.

[0115] According to some embodiments of the present invention, such as Figure 4 and Figure 41 shown, pulleys 315 are arranged on both two support brackets 312. The first transmission assembly 41 is wound around the two pulleys 315. The two pulleys 315 are arranged at intervals along the length direction of the chute 314 (for example, Figure 7 the front-back direction shown in the figure). By means of the two pulleys 315, it can be ensured that the first transmission assembly 41 is always in a taut state during the movement, and it is convenient to turn the first transmission assembly 41, so that the first transmission assembly 41 meets the required connection and movement requirements, ensuring the reliable movement of the first transmission assembly 41.

[0116] In some embodiments, such as Figure 4 , Figures 7 - 10 , Figure 14 , Figure 15 , Figure 19 , Figure 20 and Figure 42 shown, pulley boxes 316 are arranged on both two support brackets 312. The two pulleys 315 are respectively installed in the two pulley boxes 316. The pulley boxes 316 can protect the pulleys 315, avoiding damage caused by the exposure of the pulleys 315, which is beneficial to extending the service life of the pulleys 315. And two wire outlets 317 are arranged on the pulley boxes 316. The first transmission assembly 41 can extend in and out from the two wire outlets 317 to achieve the required connection requirements of the first transmission assembly 41.

[0117] In some embodiments of the present invention, such as Figure 3 , Figure 5 , Figure 11 , Figure 12 , Figure 16 , Figure 17 , Figure 21 and Figure 22 shown, the second transmission assembly 42 includes a cam assembly 421 and a deployment link assembly 422. The cam assembly 421 is rotatably arranged on the base 10. The first transmission assembly 41 cooperates with the cam assembly 421. The deployment link assembly 422 is connected to the cam assembly 421, the first tail wing 21 and the second tail wing 22.

[0118] When the first transmission component 41 moves, the first transmission component 41 can drive the cam component 421 to rotate. When the cam component 421 rotates, the deployment link component 422 can drive the first tail wing 21 and the second tail wing 22 to move away from or closer to each other, which can convert linear motion into rotational motion and then convert it into translational motion of the first tail wing 21 and the second tail wing 22 through the deployment link component 422, realizing the transmission and conversion of motion. Thus, during the upward movement of the base 10, the first tail wing 21 and the second tail wing 22 are driven to move away from each other, and during the downward movement of the base 10, the first tail wing 21 and the second tail wing 22 are driven to move closer to each other. The structure of the second transmission component 42 is simple, which can reduce production costs.

[0119] According to some embodiments of the present invention, such as Figure 11 , Figure 12 , Figure 16 , Figure 17 , Figure 21 , Figure 22 , Figure 36 and Figure 37 shown, the cam component 421 includes a cam body 61 and a grooved pulley 62. The cam body 61 and the grooved pulley 62 are rotatably arranged on the base 10. The grooved pulley 62 is located on one side of the cam body 61. The cam body 61 is provided with a toggle block 611, and the grooved pulley 62 is provided with a mating groove 621. The first transmission component 41 is engaged with the outer peripheral wall of the cam body 61, and the grooved pulley 62 is connected to the deployment link component 422. Thus, the movement of the first transmission component 41 can drive the cam body 61 to rotate, so that the toggle block 611 can extend into the mating groove 621 to drive the grooved pulley 62 to rotate. The rotation of the grooved pulley 62 can drive the deployment link component 422 to drive the first tail wing 21 and the second tail wing 22 to move away from or closer to each other, realizing the required movement requirements. The control is simple, and the structure of the cam component 421 is simple, which can reduce production costs.

[0120] In some embodiments, such as Figure 5 , Figure 11 , Figure 12 , Figure 16 , Figure 17 , Figure 21 , Figure 22 , Figure 30 and Figure 31As shown, the cam assembly 421 also includes a cam housing 63, which includes a first housing 631 and a second housing 632 that cover each other, and the cam body 61 and the groove wheel 62 are rotatably located between the first housing 631 and the second housing 632. The cam body 61 and the groove wheel 62 can be protected by the first housing 631 and the second housing 632 to prevent the cam body 61 and the groove wheel 62 from being exposed and damaged, which is beneficial to extending the service life of the cam assembly 421.

[0121] In some embodiments, Figure 31 As shown, the side of the second shell 632 facing the first shell 631 (eg Figure 3 The first rotating shaft 633 and the second rotating shaft 634 are provided on the second shell 632 at intervals. The cam body 61 is rotatably provided on the first rotating shaft 633, and the groove wheel 62 is rotatably provided on the second rotating shaft 634, so that the cam body 61 and the groove wheel 62 can be rotatably provided on the second shell 632, ensuring that the cam body 61 and the groove wheel 62 are reliably limited in the second shell 632 to avoid movement, making the rotation more reliable.

[0122] In some embodiments of the present invention, Figure 36 and Figure 37 As shown, an arc groove 622 is provided on the outer peripheral wall of the groove wheel 62, and the arc groove 622 is located on one side of the width direction of the matching groove 621. The cam body 61 includes a body part 612 and a protrusion 613. The body part 612 is cylindrical, and the protrusion 613 is provided on the outer peripheral wall of the body part 612. The toggle block 611 is provided on the protrusion 613, and the arc groove 622 can be matched with the outer peripheral wall of the body part 612. When the cam body 61 rotates, the arc groove 622 cooperates with the outer peripheral wall of the body part 612 to prevent the groove wheel 62 from rotating, and has a certain invalid stroke tolerance. After the toggle block 611 extends into the matching groove 621, it can drive the groove wheel 62 to rotate, thereby driving the deployment link assembly 422 to drive the first tail wing 21 and the second tail wing 22 to move in a direction away from or close to each other.

[0123] In this way, it is possible to unfold the first tail wing 21 and the second tail wing 22 after the lifting device 30 drives the first tail wing 21 and the second tail wing 22 to rise a certain distance, or to drive the first tail wing 21 and the second tail wing 22 to descend after the first tail wing 21 and the second tail wing 22 are closed, thereby effectively preventing the first tail wing 21 and the second tail wing 22 from colliding with the vehicle body 200 during the lifting or lowering process, thereby ensuring that the tail wing assembly 100 moves stably and reliably.

[0124] According to some embodiments of the present invention, Figure 11 , Figure 12 ,Figure 16 , Figure 17 , Figure 21 , Figure 22 , Figures 38 - 40 As shown in Figures 38 - 40 , the deployment link assembly 422 includes a first deployment link 71, a second deployment link 72, and a third deployment link 73. The cam assembly 421 is connected to the first deployment link 71, enabling the connection between the cam assembly 421 and the deployment link assembly 422. One end of the second deployment link 72 and one end of the third deployment link 73 are respectively rotatably connected to both ends of the first deployment link 71 in the length direction. Moreover, the end of the second deployment link 72 away from the first deployment link 71 is rotatably connected to the first tail fin 21, such that the second deployment link 72 can drive the first tail fin 21 to move. The end of the third deployment link 73 away from the first deployment link 71 is rotatably connected to the second tail fin 22, such that the third deployment link 73 can drive the second tail fin 22 to move.

[0125] Thus, when the cam assembly 421 rotates, the cam assembly 421 can drive the first deployment link 71 to rotate. The rotation of the first deployment link 71 can drive the first deployment link 71 and the second deployment link 72 to move away from or closer to each other, thereby enabling the first tail fin 21 and the second tail fin 22 to move away from or closer to each other, achieving the required driving requirements. Moreover, the structure of the deployment link assembly 422 is simple, facilitating processing and manufacturing, and conducive to reducing production costs.

[0126] In some embodiments, the end of the second deployment link 72 away from the first deployment link 71 is connected to the first tail fin 21 through a pin shaft, making the connection between the second deployment link 72 and the first tail fin 21 reliable, facilitating the second deployment link 72 to drive the first tail fin 21 to move, and the connection structure is simple, which is conducive to reducing production costs.

[0127] In some embodiments, the end of the third deployment link 73 away from the first deployment link 71 is connected to the second tail fin 22 through a pin shaft, making the connection between the third deployment link 73 and the second tail fin 22 reliable, facilitating the third deployment link 73 to drive the second tail fin 22 to move, and the connection structure is simple, which is conducive to reducing production costs.

The first body 11 is connected to the lifting device 30. The first body 11 is located above the second body 12, and the first body 11 is connected to the second body 12, enabling the connection between the base 10 and the lifting device 30. A part of the unfolding link assembly 422 and the cam assembly 421 are located between the first body 11 and the second body 12, which can prevent the cam assembly 421 from being exposed and damaged, is beneficial to extending the service life of the cam assembly 421, and makes the structure compact, can reduce the occupied space, and is beneficial to improving the aesthetic appearance. In addition, both ends of the unfolding link assembly 422 pass through the first body 11, enabling both ends of the unfolding link assembly 422 to be connected to the first tail wing 21 and the second tail wing 22 to meet the required connection requirements.

[0129] In some embodiments, such as Figure 2 , Figure 3 , Figure 5 , Figure 13 , Figure 18 and Figure 47 As shown, the base 10 further includes a decorative plate 16. The decorative plate 16 is located on the upper side of the first body 11 and between the first tail wing 21 and the second tail wing 22, which can improve the structural strength of the base 10, and the internal structure of the first body 11 can be blocked by the decorative plate 16, having good aesthetics.

[0130] According to some embodiments of the present invention, such as Figure 3 , Figure 5 and Figure 28 As shown, a slide rail 13 is provided on the base 10. The slide rail 13 extends along the length direction of the base 10. Slide holes 23 are provided on both the first tail wing 21 and the second tail wing 22. The slide rail 13 passes through the slide holes 23. Through the cooperation of the slide holes 23 and the slide rail 13, the slide rail 13 can play a role in guiding and positioning, making the movement of the first tail wing 21 and the second tail wing 22 on the base 10 smoother and more stable, and being beneficial to improving the movement reliability and accuracy of the first tail wing 21 and the second tail wing 22.

[0131] In some embodiments, such as Figure 3 , Figure 5 and Figure 28As shown, there are multiple slide rails 13, and the multiple slide rails 13 are arranged at intervals along the length direction and / or the width direction of the base 10. That is, the multiple slide rails 13 can be arranged at intervals along the length direction of the base 10, or the multiple slide rails 13 can be arranged at intervals along the width direction of the base 10, or the multiple slide rails 13 can be arranged at intervals along both the length direction and the width direction of the base 10. The sliding holes 23 of the first tail fin 21 and the sliding holes 23 of the second tail fin 22 are multiple and correspond one by one to the slide rails 13. By the cooperation of the multiple slide rails 13 and the multiple sliding holes 23, it can ensure the reliable movement of the first tail fin 21 and the second tail fin 22 and avoid skew.

[0132] In the embodiment of the present utility model, the number of the slide rails 13 can be flexibly set according to the actual situation. For example, as shown in Figure 3 there are six slide rails 13, or there can be two, three, four, five, seven or more, which are all within the protection scope of the present utility model.

[0133] In some embodiments, as shown in Figure 3 、 Figure 5 、 Figure 27 and Figure 29 two connecting brackets 15 are provided above the base 10. The two connecting brackets 15 are respectively arranged opposite to the first tail fin 21 and the second tail fin 22. Support members 14 are provided above both of the two connecting brackets 15. The slide rails 13 are arranged on the support members 14. The support members 14 can fix the slide rails 13 to ensure the reliable fixation of the slide rails 13 on the connecting brackets 15. Moreover, the support members 14 are arranged on the base 10 through the connecting brackets 15, which can reduce the structural complexity of the base 10 and is beneficial to reducing the manufacturing cost.

[0134] In some embodiments, as shown in Figure 5 there are multiple (greater than or equal to two) support members 14 arranged at intervals along the length direction of the slide rails 13. The multiple support members 14 can support multiple different positions of the slide rails 13 to ensure the reliable support of the slide rails 13 and avoid skew.

[0135] In some embodiments of the present utility model, as shown in Figure 4 and Figure 35 the deployment device 40 further includes a protective cover 43. The protective cover 43 extends along the length direction of the first transmission component 41. The protective cover 43 is sleeved outside the first transmission component 41. The protective cover 43 can protect the first transmission component 41 to avoid damage caused by the exposure of the first transmission component 41, which is beneficial to extending the service life of the first transmission component 41. Moreover, the protective cover 43 can limit the position of the first transmission component 41 to ensure the structural compactness.

[0136] In some embodiments where pulley boxes 316 are provided on both support brackets 312, the two ends in the length direction of the protective sleeve 43 are respectively connected to one of the wire outlets 317 of the two pulley boxes 316, which can limit the protective sleeve 43, ensure reliable limitation of the protective sleeve 43, prevent the protective sleeve 43 from moving, and thus ensure reliable movement of the first transmission assembly 41.

[0138] For example, in some embodiments, as Figures 3 - 5 , Figure 34 shown, the first transmission assembly 41 can be a cable. By using the cable, the transmission efficiency between the lifting device 30 and the deployment device 40 can be increased, the structural design can be made more reasonable, the structural stability can be ensured, the occupied space can be reduced, and the economy is high.

[0140] In some embodiments where the cam body 61 includes a body portion 612 and a protrusion portion 613, as Figure 36 shown, the cable is wound around the outer peripheral wall of the cam body 61. A groove 614 extending along the circumferential direction of the body portion 612 is provided on the body portion 612, and the cable is wound in the groove 614. The groove 614 can limit the cable and prevent the cable from moving in the axial direction of the body portion 612 (for example, Figure 3 the up and down direction shown in

[0141] For example, in some embodiments, the first transmission assembly 41 can be a chain, and the cam assembly 421 is formed as a sprocket. The chain cooperates with the sprocket, which can meet the transmission requirements between the lifting device 30 and the deployment device 40 and ensure the accuracy of movement.

[0143] Refer to Figures 3 - 5As shown, the fin assembly 100 includes a base 10, a first fin 21, a second fin 22, a lifting device 30 and a deploying device 40. The first fin 21 and the second fin 22 are movably disposed on the base 10 along the length direction of the base 10 and are arranged in the length direction of the base 10.

[0144] As Figure 3 and Figure 4 shown, the deploying device 40 includes a first transmission assembly 41 and a second transmission assembly 42. The first transmission assembly 41 is a cable.

[0145] As Figure 3 and Figure 5As shown, the second transmission assembly 42 includes a cam assembly 421 and a deployment link assembly 422. The cam assembly 421 includes a cam body 61 and a grooved pulley 62. The cam body 61 includes a body portion 612 and a convex portion 613. The deployment link assembly 422 includes a first deployment link 71, a second deployment link 72, and a third deployment link 73. The cam body 61 is rotatably provided on the base 10. The cable is wound around the outer peripheral wall of the cam body 61. The grooved pulley 62 is rotatably provided on the base 10 and is located on one side of the cam body 61. A mating groove 621 is provided on the grooved pulley 62, and an arc-shaped groove 622 is provided on the outer peripheral wall of the grooved pulley 62. The arc-shaped groove 622 is located on one side in the width direction of the mating groove 621. The body portion 612 is cylindrical, the convex portion 613 is provided on the outer peripheral wall of the body portion 612, and a toggle block 611 is provided on the convex portion 613. The grooved pulley 62 is connected to the first deployment link 71. One end of the second deployment link 72 and one end of the third deployment link 73 are respectively rotatably connected to both ends in the length direction of the first deployment link 71. And the end of the second deployment link 72 far from the first deployment link 71 is rotatably connected to the first tail wing 21, and the end of the third deployment link 73 far from the first deployment link 71 is rotatably connected to the second tail wing 22.

[0146] When the tail wing assembly 100 is not opened, as Figure 6 , Figure 7 and Figure 9 shown, the first tail wing 21 and the second tail wing 22 are not raised and are in a closed state. The left end of the cable is at a position close to the pulley 315 on the left side, and the right end of the cable is at a position far from the pulley 315 on the right side. The upper ends of the first lifting link 51 and the second lifting link 52 are both at the lowermost positions. The toggle block 611 does not enter the mating groove 621, and the grooved pulley 62, the first deployment link 71, the second deployment link 72, the third deployment link 73, the first tail wing 21, and the second tail wing 22 all remain stationary.

[0147] When it is necessary to open the tail wing assembly 100, as Figures 11 - 17As shown, the motor 321 drives the motor shaft 322 to rotate, and the motor shaft 322 drives the driving wheel 324 and the first lifting link 51 to swing upward, and the driving wheel 324 drives the driven wheel 325 to rotate through the gear meshing transmission, so that the second lifting link 52 connected to the driven wheel 325 swings upward, so that the first lifting link 51 and the second lifting link 52 drive the supporting bracket 312 to swing upward, thereby realizing the lifting action of the first tail 21 and the second tail 22. At the same time, the first lifting link 51 on the left side drives the left end of the cable to slide downward along the length direction of the slide slot 314, gradually away from the pulley 315 on the left side, and the first lifting link 51 on the right side drives the right end of the cable to slide downward along the length direction of the slide slot 314, gradually approaching the pulley 315 on the right side, so that the cable moves to the left and drives the cam body 61 to rotate clockwise, so that the toggle block 611 gradually enters the matching groove 621, driving the groove wheel 62 to rotate in the opposite direction. The rotation of the groove wheel 62 can drive the first deployment link 71 to rotate counterclockwise, thereby driving the second deployment link 72 to move to the left and the third deployment link 73 to move to the right, so that the first tail wing 21 connected to the second deployment link 72 moves to the left, and the second tail wing 22 connected to the third deployment link 73 moves to the right. For example, the movement direction is as follows: Figure 12 Indicated by the arrow.

[0148] like Figures 18 - 22 As shown, the first lifting link 51 on the left side continuously drives the left end of the cable to slide downward along the length direction of the slide slot 314 to reach the lowest end of the slide slot 314, and the cable is extended to the longest on the left side; the first lifting link 51 on the right side drives the right end of the cable to slide downward along the length direction of the slide slot 314 to reach the lowest end of the slide slot 314, and the cable is shortened to the shortest on the right side. At the same time, the control groove wheel 62 continues to rotate to drive the first deployment link 71 to rotate counterclockwise, thereby driving the second deployment link 72 to move to the farthest end to the left, and driving the third deployment link 73 to move to the farthest end to the right, so that the first tail 21 moves to the left and the second tail 22 moves to the right, so that the tail assembly 100 is fully deployed. For example, the movement direction is as follows: Figure 17 Indicated by the arrow.

[0149] When the tail assembly 100 needs to be closed, the driving action is opposite to the direction of opening the tail assembly 100. The motor 321 drives the motor shaft 322 to rotate in the opposite direction, and the motor shaft 322 drives the driving wheel 324 and the first lifting link 51 to swing downward. The driving wheel 324 drives the driven wheel 325 to rotate in the opposite direction through gear meshing transmission, so that the second lifting link 52 connected to the driven wheel 325 swings downward, so that the first lifting link 51 and the second lifting link 52 drive the support bracket 312 to swing downward together, thereby realizing the landing action of the first tail 21 and the second tail 22. At the same time, the first lifting link 51 on the left side drives the left end of the cable to gradually slide upward from the lowest point along the length direction of the slide groove 314, gradually approaching the pulley 315 on the left side, and the first lifting link 51 on the right side drives the right end of the cable to gradually slide upward from the lowest point along the length direction of the slide groove 314, gradually moving away from the pulley 315 on the right side, so that the cable moves to the right and drives the cam body 61 to rotate counterclockwise, and the toggle block 611 slides in the matching groove 621, driving the groove wheel 62 to rotate clockwise. The rotation of the groove wheel 62 can drive the first deployment link 71 to rotate clockwise, thereby driving the second deployment link 72 to move to the right and driving the third deployment link 73 to move to the left, so that the first tail wing 21 connected to the second deployment link 72 moves to the right, and the second tail wing 22 connected to the third deployment link 73 moves to the left, realizing the landing and closing of the car tail.

[0150] When the toggle block 611 is disengaged from the matching groove 621, the main body 612 continues to rotate counterclockwise in the arc groove 622, so that the cable moves from left to right. At this time, the groove wheel 62, the first deployment link 71, the second deployment link 72, the third deployment link 73, the first tail 21 and the second tail 22 remain stationary and no longer move. The first tail 21 and the second tail 22 remain in a closed state, the first lifting link 51 and the second lifting link 52 continue to swing downward, the first lifting link 51 on the left side continues to drive the left end of the cable to slide upward along the length direction of the slide groove 314, gradually approaching the pulley 315 on the left side and reaching the highest point, and the first lifting link 51 on the right side continues to drive the right end of the cable to slide upward along the length direction of the slide groove 314, gradually approaching the pulley 315 on the right side and reaching the highest point. Finally, the first lifting link 51 and the second lifting link 52 swing to the lowest point, and the second lifting link 52 drives the support bracket 312 to descend to the lowest point, and the car tail wing is closed.
