Therefore, when the motor shaft 322 rotates, the motor shaft 322 can drive the driving wheel 324 to rotate relative to the support seat 311, and the driving wheel 324 is meshed with the driven wheel 325 to drive the driven wheel 325 to rotate, and 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 seat 311, and the height adjustment of the second lifting link 52 is achieved.

[0105] Therefore, the gear assembly 323 is used to facilitate the synchronous movement of the first lifting link 51 and the second lifting link 52, avoiding problems such as misalignment, making the movement more reliable, and 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 easy 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, Figure 4 , Figure 8 and Fig.10 As shown, the driving wheel 324 is coaxial with the first lifting link 51 , which can make the structure of the lifting device 30 compact and reduce the occupied space, thereby facilitating reducing the layout space requirement 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 via a pin shaft, so that the lower end of the second lifting link 52 is reliably connected to the driven wheel 325, which facilitates the driven wheel 325 to drive the second lifting link 52 to rotate synchronously, and the connection structure is simple, which is conducive to reducing production costs.

[0108] In some embodiments, Figure 4 , Figure 8 and Fig.10 , Fig.50 and Fig.51 As shown, the gear assembly 323 also includes a gear box 80, which includes an inner plate 81 and an outer plate 82 that cover each other, and 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 to avoid damage caused by exposure of the driving wheel 324 and the driven wheel 325, which is beneficial to extending the service life of the gear assembly 323.

The first lifting link 51 slides in the slide groove 314 to drive the first transmission component 41 to move along the length direction of the base 10, and the transmission of the second transmission component 42 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.

[0110] Thus, the first tail 21 and the second tail 22 can be lifted and deployed or lowered and closed only by one driving mechanism 32, that is, the first tail 21 and the second tail 22 can be moved in two directions, vertically upward and horizontally. The movement of the first tail 21 and the second tail 22 can be simplified, and the problem of complex driving and moving mechanism existing in the opening and closing process of the three-stage tail wing in the related art is avoided, so that the control is convenient, and it is avoided that the lifting device 30 and the deployment device 40 are driven separately by multiple driving mechanisms 32, so the number of driving mechanisms 32 can be reduced, which is convenient for reducing the manufacturing cost, and at the same time it can reduce the occupied space and reduce the requirements for the layout space of the tail assembly 100.

[0112] In some embodiments, a connecting protrusion 441 is provided on the slider 44, and the connecting protrusion 441 is passed through the first lifting link 51, so as to realize the connection between the first lifting link 51 and the slider 44, ensure that the first lifting link 51 and the slider 44 are reliably connected, and has a simple structure, which can reduce production costs and improve assembly efficiency.

[0113] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, there are two lifting assemblies 31, and the two lifting assemblies 31 are spaced apart along the length direction of the base 10. The two lifting assemblies 31 can improve the stability and balance of the first tail 21 and the second tail 22 during the lifting process, and the two lifting assemblies 31 can work together to effectively disperse the load, while reducing the risk of overall failure caused by failure of a single component.

[0114] In some embodiments, the drive mechanism 32 includes a motor 321 and a gear assembly 323, such as Figure 4 As shown, there are two gear assemblies 323 corresponding to the lifting assemblies 31, the motor shaft 322 extends along the length direction of the base 10, the two driving wheels 324 are arranged at intervals along the length direction of the motor shaft 322, and the two driving wheels 324 are fixed on the motor shaft 322, and the lower ends of the two second lifting links 52 are connected to the corresponding driven wheels 325 and rotate synchronously. Therefore, the control of the two lifting assemblies 31 can be realized by one motor 321, which makes the control convenient and can reduce the production cost.

The cam assembly 421 is rotatably disposed on the base 10. The first transmission assembly 41 cooperates with the cam assembly 421. The unfolding 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 unfolding connecting rod component 422 can drive the first tail 21 and the second tail 22 to move in a direction away from each other or closer to each other, and can convert linear motion into rotational motion, and then convert it into translational motion of the first tail 21 and the second tail 22 through the unfolding connecting rod component 422, thereby realizing the transmission and conversion of motion, thereby achieving the process of driving the first tail 21 and the second tail 22 to move away from each other during the upward movement of the base 10, and driving the first tail 21 and the second tail 22 to move towards each other during the downward movement of the base 10. The second transmission component 42 has a simple structure and can reduce production costs.

[0119] According to some embodiments of the present invention, Fig.11 , Fig.12 , Fig.16 , Fig.17 , Fig.21 , Fig. 22 , Fig.36 and Fig.37As shown, the cam assembly 421 includes a cam body 61 and a groove wheel 62, the cam body 61 and the groove wheel 62 are rotatably arranged on the base 10, the groove wheel 62 is located at one side of the cam body 61, the cam body 61 is provided with a toggle block 611, the groove wheel 62 is provided with a matching groove 621, the first transmission assembly 41 is matched with the outer peripheral wall of the cam body 61, and the groove wheel 62 is connected to the deployment link assembly 422. Thus, the movement of the first transmission assembly 41 can drive the cam body 61 to rotate, so that the toggle block 611 can extend into the matching groove 621 to drive the groove wheel 62 to rotate, and the rotation of the groove wheel 62 can drive the deployment link assembly 422 to drive the first tail 21 and the second tail 22 to move in a direction away from each other or close to each other, so as to achieve the required movement requirements, and the control is simple, and the structure of the cam assembly 421 is simple, which can reduce the production cost.

[0120] In some embodiments, Figure 5 , Fig.11 , Fig.12 , Fig.16 , Fig.17 , Fig.21 , Fig. 22 , Fig.30 and Fig.31 As 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, Fig.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, Fig.36 and Fig.37As 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, Fig.11 , Fig.12 , Fig.16 , Fig.17 , Fig.21 , Fig. 22 , Figure 38-Figure 40 As shown, the deployment link assembly 422 includes a first deployment link 71, a second deployment link 72 and a third deployment link 73, and the cam assembly 421 is connected to the first deployment link 71, so as to realize 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 the two ends of the length direction of the first deployment link 71, and the end of the second deployment link 72 away from the first deployment link 71 is rotatably connected to the first tail wing 21, so that the second deployment link 72 can drive the first tail wing 21 to move, and the end of the third deployment link 73 away from the first deployment link 71 is rotatably connected to the second tail wing 22, so that the third deployment link 73 can drive the second tail wing 22 to move.

[0125] Therefore, when the cam assembly 421 rotates, the cam assembly 421 can drive the first unfolding link 71 to rotate, and the rotation of the first unfolding link 71 can drive the first unfolding link 71 and the second unfolding link 72 to move in a direction away from or close to each other, thereby enabling the first tail 21 and the second tail 22 to move in a direction away from or close to each other, achieving the required driving requirements, and the unfolding link assembly 422 has a simple structure, which is easy to process and manufacture, and is conducive to reducing production costs.

A sliding hole 23 is provided on the first tail 21 and the second tail 22. The slide rail 13 is penetrated into the sliding hole 23, and cooperates with the slide rail 13 through the sliding hole 23, so that the slide rail 13 can play a guiding and positioning role, so that the movement of the first tail 21 and the second tail 22 on the base 10 is more stable and smooth, which is beneficial to improve the movement reliability and accuracy of the first tail 21 and the second tail 22.

[0131] In some embodiments, Figure 3 , Figure 5 and Fig.28 As shown, there are multiple slide rails 13, and the multiple slide rails 13 are spaced apart along the length direction and / or width direction of the base 10, that is, the multiple slide rails 13 can be spaced apart along the length direction of the base 10, or the multiple slide rails 13 can be spaced apart along the width direction of the base 10, or the multiple slide rails 13 can be spaced apart along the length direction and the width direction of the base 10, and the sliding holes 23 of the first tail wing 21 and the sliding holes 23 of the second tail wing 22 are multiple corresponding to the slide rails 13 one by one.

The slide rail 13 can be fixed by the support member 14 to ensure that the slide rail 13 is reliably fixed on the connecting bracket 15. The support member 14 is provided on the base 10 through the connecting bracket 15, which can reduce the structural complexity of the base 10 and is conducive to reducing the manufacturing cost.

[0148] like Figure 18-Figure 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: Fig.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.
