[0029] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure.

[0032] Figure 1 1 is a schematic structural diagram of an electric tail wing system in one state according to an embodiment of the present disclosure. Figure 2 3 is a schematic structural diagram of an electric tail wing system in a state from another angle according to an embodiment of the present disclosure.

Figure 43 is a schematic structural diagram of an electric tail wing system in another state at another angle according to an embodiment of the present disclosure.

[0033] like Figures 1 to 4 As shown, the electric tail system of the present disclosure includes a base 100 , a driving device 200 , a first tail component 300 , a second tail component 400 and other structures.

[0034] When the electric rear wing system of the present disclosure is in use, the base 100 can be fixed to a vehicle body or a trunk lid or other components, thereby achieving the fixation of the electric rear wing system of the present disclosure.

[0035] The base 100 can be implemented by using a structure in the prior art. The present disclosure will not further elaborate on the structure of the base 100.

[0036] The driving device 200 of the present disclosure is used to provide driving force. In one embodiment, the driving device 200 can be fixed to the base 100 and located below the base 100.

[0037] The driving device 200 includes a driving shaft, that is, when the driving device 200 is working, the driving shaft can generate a rotation motion. The rotation motion includes rotation along a first direction and rotation along a second direction, and the first direction and the second direction are opposite.

[0038] The driving device 200 disclosed in the present invention can be implemented using solutions in the prior art, for example, using the structure in CN202011442352.4, which will not be described in detail in this disclosure.

[0039] Driven by the driving force provided by the driving device 200, the driving device 200 of the present disclosure can drive the first tail wing component 300 to move between a first position and a second position, wherein, compared with the first position, when the first tail wing component 300 is in the second position, the first tail wing component 300 can provide greater grip to the vehicle; and the driving device 200 can drive the second tail wing component 400 to move between a third position and a fourth position, wherein, compared with the third position, when the second tail wing component 400 is in the fourth position, the second tail wing component 400 can provide greater grip to the vehicle.

[0040] Thus, when the electric rear wing system of the present disclosure is in use, when the vehicle is moving at a low speed, the first rear wing component 300 can be in the first position, and the second rear wing component 400 can be in the third position. This reduces the wind resistance of the vehicle, thereby improving the electric vehicle's range and saving energy. On the other hand, when the vehicle is moving at a high speed or when braking suddenly, the first rear wing component 300 can be in the second position, and the second rear wing component 400 can be in the fourth position. This allows the vehicle to have better grip and thus improve safety performance.

[0041] In one embodiment, a recess is provided on the first fin component 300 . When the first fin component 300 is in the first position and the second fin component 400 is in the third position, at least a portion of the first fin component 300 is located in the recess.

[0042] Based on this, the first tail wing component 300 of the present disclosure has a larger area and can also be referred to as the main tail wing, while the second tail wing component 400 has a smaller area and can also be referred to as the auxiliary tail wing. Because the second tail wing component 400 can be at least partially disposed within the recess of the first tail wing component 300, the electric tail wing system of the present disclosure has a smaller size, making it convenient to place the electric tail wing system on the vehicle's trunk lid.

[0043] The recess of the first rear wing component 300 of the present disclosure has both an upward and a rearward opening, facilitating the movement of the second rear wing component 400 into and out of the recess. In other words, if the recess had four sidewalls, not only would the fit between the first rear wing component 300 and the trunk lid need to be considered, but also the fit between the second rear wing component 400 and the first rear wing component 300 would need to be considered, increasing the design complexity of the electric rear wing system.

[0044] In a preferred embodiment, when the first fin component 300 is in the first position and the second fin component 400 is in the third position, the upper surface of the first fin component 300 is substantially flush with the upper surface of the second fin component 400 .

[0045] More preferably, the rear surface of the first spoiler component 300 is also substantially flush with the rear surface of the second spoiler component 400. Thus, the electric spoiler system of the present disclosure has a smaller volume, thereby being adaptable to more vehicle models and expanding usage scenarios.

[0046] The term "substantially flush" in the present disclosure does not specifically refer to the case where the upper surfaces of the first and second tail wing components 300, 400 are both planar. It also includes the case where the upper surfaces of the first and second tail wing components 300, 400 are curved. Specifically, the upper surface of the first tail wing component 300 can be an upwardly convex curved surface. In this case, the upper surface of the second tail wing component 400 can also be an upwardly convex curved surface. In this case, the upper surfaces of the first and second tail wing components 300, 400 form a continuous curved surface. This continuous curved surface can adapt to the upper surface of the trunk lid, so that the electric tail system of the present disclosure does not protrude from the upper surface of the trunk lid when not in operation.

[0047] When the first fin component 300 is in the second position and the second fin component 400 is in the fourth position, at least a portion of the second fin component 400 protrudes from the upper surface of the first fin component 300 .

[0048] Thus, when the electric rear wing system of the present disclosure is in use, air flows not only over the upper surface of the first rear wing component 300, but also over the upper surface of the second rear wing component 400. Because the second rear wing component 400 protrudes from the first rear wing component 300, the electric rear wing system of the present disclosure can provide greater downforce than conventional systems that only have one rear wing component, thereby effectively improving vehicle stability and safety.

[0049] When the second tail wing component 400 moves from the third position to the fourth position, the second tail wing component 400 rotates by a predetermined angle relative to the first tail wing component 300. In other words, the position of the second tail wing component 400 of the present disclosure changes during its movement from the third position to the fourth position. However, the change in angle is more significant relative to that of the first tail wing component 300.

[0050] Specifically, in this state, that is, when the first tail wing component 300 is in the second position and the first tail wing component 300 is in the fourth position, an angle with an opening facing backward is formed between the first tail wing component 300 and the second tail wing component 400 of the present disclosure. Therefore, the front end of the first tail wing component 300 of the present disclosure is lower than the rear end of the first tail wing component 300, and at the same time, the front end of the second tail wing component 400 is also lower than the rear end of the second tail wing component 400.

[0051] Based on this structure, the electric rear wing system disclosed in the present invention can provide greater downforce to the vehicle, thereby making the vehicle have better stability and safety.

[0052] Those skilled in the art will appreciate that the first position of the present disclosure may be the state in which the electric rear spoiler system is retracted into the trunk lid, and the second position may be the state in which the electric rear spoiler system is moved to the maximum open position. Furthermore, the electric rear spoiler system of the present disclosure may be suspended at any position between the first and second positions.

[0053] For example, the transmission structure of the driving device 200 of the present disclosure may use a worm gear assembly with a self-locking function, so that the first tail component 300 and the second tail component 400 can be suspended at an ideal position by the driving device 200 with a self-locking function.

[0054] Refer again Figures 1 to 4 In the present disclosure, the drive device 200 synchronously drives the first tail wing component 300 and the second tail wing component 400 to move. As a result, the electric tail wing system of the present disclosure can have fewer drive devices 200, and accordingly, lower costs. In another implementation, the present disclosure can also be provided with two drive devices 200, one for driving the first tail wing component 300 and the other for driving the second tail wing component 400, thereby enabling the two tail wing components to move independently.

[0055] In a more preferred embodiment, when the drive device 200 drives the first rear wing component 300 from the first position to the second position, it also drives the second rear wing component 400 from the third position to the fourth position. Thus, the electric rear wing system of the present disclosure can be conveniently controlled. That is, by rotating the drive device 200 in one direction, the downforce provided by the electric rear wing system to the vehicle will gradually increase. Conversely, when the drive device 200 rotates in the other direction, the downforce provided by the electric rear wing system to the vehicle will gradually decrease. Thus, when the electric rear wing system of the present disclosure is in use, precise control of the electric rear wing system can be achieved simply by controlling the speed and number of revolutions of the motor of the drive device.

[0056] Figures 5 to 7 1 is a schematic structural diagram of a connecting rod assembly 500 of an electric tail system according to an embodiment of the present disclosure.

[0057] The driving shaft of the driving device 200 of the present disclosure is connected to the first and second empennage components 300 and 400 via the connecting rod assembly 500 . Thus, the driving force of the driving device 200 of the present disclosure can be converted into position changes of the first and second empennage components 300 and 400 via the connecting rod assembly 500 .

[0058] Specifically, two connecting rod assemblies 500 are provided, one at each end of the second empennage component 400. In the present disclosure, a through hole is defined on the bottom wall of the recess of the first empennage component 300, through which at least a portion of the connecting rod assembly 500 can pass, positioned above the first empennage component 300. Thus, the connecting rod assembly 500 of the present disclosure can be connected to the second empennage component 400.

[0059] In a specific embodiment, Figure 5 The connecting rod assembly 500 may include a seat component 501, a crank 502, a first connecting rod 503, a second connecting rod 504, a third connecting rod 505, a first fixed seat 506, a fourth connecting rod 507, a fifth connecting rod 508, a second fixed seat 509 and a sixth connecting rod 510.

[0060] Specifically, one end of the drive shaft of the drive device 200 of the present disclosure is rotatably disposed on the seat component 501. In a preferred embodiment, the drive shaft may not be supported by the seat component 501, but only be able to rotate relative to the seat component 501.

[0061] One end of the crank 502 is fixedly connected to one end of the drive shaft; thus, when the drive shaft rotates, the crank 502 can rotate around the rotation axis of the drive shaft.

[0062] One end of the first connecting rod 503 is rotatably connected to the other end of the crank 502 ; moreover, the rotation axis of the first connecting rod 503 relative to the crank 502 is parallel to the rotation axis of the drive shaft.

[0063] One end of the second connecting rod 504 is rotatably arranged on the seat part 501, and the other end of the first connecting rod 503 is rotatably connected to the middle part of the second connecting rod 504; thus, the crank 502, the first connecting rod 503 and the second connecting rod 504 disclosed in the present invention can form a four-bar structure. At this time, when the drive shaft rotates, the other end of the second connecting rod 504 will produce a swinging motion.

[0064] One end of the third link 505 is rotatably provided on the seat component 501; one end of the first fixed seat 506 is rotatably provided on the other end of the second link 504, and the other end of the first fixed seat 506 is rotatably provided on the other end of the third link 505; thus, the second link 504, the third link 505 and the first fixed seat 506 disclosed in the present invention will form a four-bar linkage mechanism. At this time, the first fixed seat 506 will produce a posture change, thereby driving the first tail wing component 300 installed on the first fixed seat 506 to produce a posture change.

[0065] Moreover, one end of the fourth link 507 is hinged to one end of the first fixed seat 506; one end of the fifth link 508 is hinged to the other end of the first fixed seat 506; one end of the second fixed seat 509 is hinged to the other end of the fourth link 507, and the other end of the second fixed seat 509 is hinged to the other end of the fifth link 508; thus, the fourth link 507, the fifth link 508 and the second fixed seat 509 of the present disclosure will form a four-link mechanism.

[0066] Furthermore, one end of the sixth connecting rod 510 is hinged to the base member 501, and the other end of the sixth connecting rod 510 is hinged to the second fixed base 509. Thus, the position and posture of the second fixed base 509 of the present disclosure can be accurately determined. Specifically, when the first fixed base 506 changes position, the second fixed base 509 will change position with the first fixed base 506. Furthermore, due to the arrangement of the sixth connecting rod 510, the second fixed base 509 will also change angle relative to the first fixed base 506. As a result, the second empennage member 400 can change angle relative to the first empennage member 300.

[0067] In a preferred embodiment, the other end of the second connecting rod 504 and one end of the fourth connecting rod 507 share the same rotation axis. In other words, the second connecting rod 504 and the fourth connecting rod 507 can be mounted on the first fixing base 506 via the same shaft. Similarly, the other end of the third connecting rod 505 and one end of the fifth connecting rod 508 share the same rotation axis, meaning that the third connecting rod 505 and the fifth connecting rod 508 can be mounted on the first fixing base 506 via the same shaft. As a result, the connecting rod assembly 500 of the present disclosure can have a simplified structure, with a reduced number of components and easy installation.

[0068] The other end of the fourth link 507 and the other end of the sixth link 510 have the same rotation axis. In other words, the fourth link 507 and the sixth link 510 can be set on the second fixed seat 509 through the same axis component. Thus, the second fixed seat 509 of the present disclosure can move along a preset motion trajectory.

[0069] In the present disclosure, the first fixing seat 506 is fixedly connected to the first tail wing component 300, and the second fixing seat 509 is fixedly connected to the second tail wing component 400. Therefore, the first tail wing component 300 and the second tail wing component 400 of the present disclosure can move independently.

[0070] According to another aspect of the present disclosure, a motor vehicle is provided, comprising the above-mentioned electric tail wing system.
