For ease of understanding, the following description is made regarding the course of movement of the drive device 3:

the driving device 3 includes a driving portion 31, a transmission assembly 32, and a driving shaft 33, wherein the driving portion 31 is an electric motor or a motor, and the transmission assembly 32 includes: the first link 321, the second link 322, and the third link 323, the first link 321 and the third link 323 being connected by the second link 322; one end of the first link 321 is connected to the output shaft 311 of the driving unit 31, the other end is connected to the second link 322, one end of the third link 323 is connected to the second link 322, and the other end is connected to the driving shaft 33.

The power generated by the rotation of the output shaft 311 of the driving part 31 is transmitted to the transmission assembly 32, and then transmitted to the driving shaft 33 through the transmission assembly 32, the driving shaft 33 drives the actuator 35 to act, and the actuator 35 controls the tail wing plate 2, so that the motion of the tail wing plate 2 can be realized, and the tail wing plate 2 can be switched between the retracted state and the open state. The mounting and connection relationships of the respective components in the driving device 3 are as follows: the driving device 3 further comprises a mounting seat 34, wherein the mounting seat 34 is arranged in the middle area of the base 1, and the mounting seat 34 is provided with a through hole; the driving unit 31 is mounted on the mounting seat 34, the driving shaft 33 rotatably penetrates the through hole, and the axis of the driving shaft 33 is parallel to the axis of the output shaft 311 of the driving unit 31. The mounting seat 34 is mounted on the second surface 12 of the base 1, the mounting seat 34 is used as a basic member for mounting the driving part 31, the driving part 31 is mounted on the mounting seat 34, the output shaft 311 of the driving part 31 is connected with the first connecting rod 321, the other end of the first connecting rod 321 is hinged with the second connecting rod 322, the other end of the second connecting rod 322 is hinged with the third connecting rod 323, the other end of the third connecting rod 323 is fixed with the driving shaft 33, the driving shaft 33 passes through the mounting seat 34, a bearing is arranged at a relative movement part, the driving shaft 33 is connected with the mounting seat 34 through the bearing, the driving shaft 33 can only rotate relative to the mounting seat 34 around the axis, and the axis direction of the driving shaft 33 is parallel to the output shaft 311 of the driving part 31.

When the output shaft 311 of the driving portion 31 rotates, the first link 321 swings with the output shaft 311, and drives the second link 322 through the first hinge point 324, and then drives the third link 323 through the second hinge point 325, and the third link 323 drives the driving shaft 33 to rotate, and the rotation of the output shaft 311 is finally converted into the rotation of the driving shaft 33, and the driving shaft 33 rotationally penetrates through the through hole of the mounting seat 34, and since the mounting seat 34 is located in the middle area of the base 1, the driving shaft 33 is more stable, that is, the middle area of the driving shaft 33 is located at the base 1.

When the output shaft 311 of the driving part 31 rotates in the first direction or the second direction within a certain range, that is, rotates in the forward and reverse directions, the driving shaft 33 swings within a corresponding range, and finally, the elevating action of the tail wing is realized. The start and stop of the driving section 31 is no longer controlled using the position sensor signal. During initialization, for example, the driving part 31 rotates positively, so that the driving part 31 drives the transmission component 32 to move, and current of the driving part 31 is monitored in the process, when the driving component reaches the limit position, the current of the driving part 31 is suddenly increased due to stalling, at the moment, the current position of the output shaft 311 of the driving part 31 is recorded, then the output shaft 311 of the driving part 31 rotates reversely, the limit position of the other side is searched according to the same method, an accurate movement section of the tail wing plate 2 can be established according to the limit positions at two sides, the position of the output shaft 311 of the driving part 31 can be controlled in the section as required, accurate control of the lifting position of the tail wing plate 2 is realized, and meanwhile, slow start and stop of the movement of the tail wing plate 2 can be realized through speed regulation of the rotation of the output shaft 311 of the driving shaft 33, so that the movement of the tail wing plate 2 is smoother and more natural. The position detection sensor of the transmission assembly 32 is eliminated, and the structure and wiring of the tail wing of the automobile provided by the embodiment of the utility model are simplified by detecting the position of the driving shaft 33 through the driving part 31 (such as a motor) with a position feedback device (such as an encoder).

The motion of the tail wing of the automobile provided by the embodiment of the utility model needs to have two stable states, namely when the tail wing plate 2 rises to the top and descends to the bottom, under the two stable states, each element needs to be kept relatively static, external load and disturbance can be resisted to a certain extent, more directly, when the tail wing descends, the tail wing cannot be sprung up by itself due to jolt and the like in running of the automobile; after the tail wing is lifted, the tail wing should not be automatically lowered under the action of air flow and the like, in order to achieve the fact that each element in the driving device 3 meets a specific geometric relation in movement, the following figure shows an outline view of the driving device 3 in a steady state, as shown in fig. 5, the output shaft 311 of the driving part 31 rotates in a counterclockwise direction, when the output shaft 311, the first hinging point 324 and the second hinging point 325 are rotated to the positions shown in fig. 5, the axes of the output shaft 311, the first hinging point 324 and the second hinging point 325 are basically in the same plane, each element is stopped in the positions, and the first connecting rod 321, the second connecting rod 322 and the third connecting rod 323 are in dead point positions when seen from the side of the driving shaft 33, namely, the driving shaft 33 cannot reversely drive the driving part 31 to rotate, and even if the driving part 31 does not use braking or other position control measures, the whole structure can still keep a steady state, namely, the driving part 31, the transmission assembly 32, the driving shaft 33 and the tail wing plate 2. When the tail vane 2 is at the first station, the tail vane 2 can be understood to move to the highest point or the lowest point when being at the first station, the output shaft 311 of the driving part 31 rotates along the first direction, and the output shaft 311 of the driving part 31 is positioned in the concave area 322a and is abutted with the second connecting rod 322; when the output shaft 311 of the driving portion 31 continues to rotate in the counterclockwise direction, the concave region 322a of the second link 322 collides with the output shaft 311 at the first limit contact region a, and the driving portion 31 cannot continue to rotate under the constraint of the geometric factor, so that the entire mechanism moves to the limit point position, and the tail vane 2 moves to the highest (low) point.

Similarly, as shown in fig. 6, when the driving portion 31 rotates clockwise to the position shown in fig. 6, the axes of the driving portion 31, the first hinge point 324 and the second hinge point 325 are also substantially in the same plane, the driving device 3 is at another dead point position, so that the stable state can be well maintained, the output shaft 311 of the driving portion 31 continues to rotate, and when the tail vane 2 is at the second station, the output shaft 311 of the driving portion 31 rotates in the second direction, and the driving shaft 33 is located in the concave area 322a and abuts against the second link 322. The concave portion of the second link 322 collides with the driving shaft 33 at the second limit contact area B, and the whole driving device 3 moves to the other side limit point position.

In fig. 7, in order to ensure stable lifting movement of the tail vane 2, the two actuators 35 are respectively located at two ends of the driving shaft 33, and both the two actuators 35 are connected with the tail vane 2, because both the two actuators 35 are connected through the driving shaft 33, that is, the two actuators 35 are coaxially connected, the synchronous action of the two actuators 35 is achieved, so that the working process of the actuator 35 for driving the tail vane 2 is more stable; of course, the number of the actuators 35 may be one, that is, one actuator 35 may be disposed at either end of the driving shaft 33.
