[0024] As shown in the accompanying Figure 2 , drive unit 3 includes shell 31, motor 32, primary worm 33, primary worm gear 34, secondary worm 35, secondary worm gear 36, drive shaft 37, motor 32 is fixedly arranged in shell 31, the output shaft of motor 32 is fixed with primary worm 33, primary worm 33, primary worm gear 34, secondary worm 35, secondary worm gear 36 and drive shaft 37 are all rotationally connected in shell 31, primary worm 33 is engaged with primary worm gear 34, primary worm gear 34 is coaxially fixed with secondary worm 35, secondary worm 35 is engaged with secondary worm gear 36, secondary worm gear 36 is fixedly sleeved on drive shaft 37.

[0025] Shell 31 includes upper shell and lower shell, and the upper shell and the lower shell are fixedly connected together by screws.

[0026] When the driving unit 3 is powered on, the motor 32 outputs a rotating shaft, which drives the driving shaft 37 to rotate through a first worm 33, a first worm wheel 34, a second worm 35, and a second worm wheel 36. Due to the rigid fixation of the connecting pipe 44, the hinge shafts 42 on the first hinge mechanism 4 and the second hinge structure 5 rotate synchronously with the driving shaft 37, driving the linkage mechanism to lift and lower, and the spoiler 1 can be opened or closed.

[0027] The housing 31 is fixed with a sensor 38, and the driving shaft 37 is sleeved with a magnetic ring 39, which is located on one side of the sensor 38.

[0028] The motor 32 is provided with a motor magnetic ring 6 and a signal acquisition circuit board 7 at the tail end.

[0029] As shown in the accompanying drawings, Figure 3 The housing 31 includes an upper shell and a lower shell, which are fixedly connected together by screws.

[0030] The first hinge mechanism 4 and the second hinge structure 5 are both composed of a bottom support 40, a hinge body 41, a hinge shaft 42, and a top support 43. The hinge body 41 is connected with the bottom support 40, the hinge shaft 42, and the top support 43. The top support 43 is fixedly connected to the spoiler 1, the hinge shaft 42 is fixedly connected to one end of the driving shaft 37, and the bottom support 40 is fixedly connected to the mounting base 2.

[0031] As shown in the accompanying drawings, Figure 4 The hinge body 41 includes a first connecting rod 45, a second connecting rod 46, a third connecting rod 47, and a fourth connecting rod 48. The first connecting rod 45 is hingedly connected to the top support 43 and the bottom support 40 at both ends, respectively. The second connecting rod 46 is hingedly connected to the rod body of the first connecting rod 45 and one end of the third connecting rod 47 at both ends, respectively. The other end of the third connecting rod 47 is fixedly connected to one end of the hinge shaft 42. The fourth connecting rod 48 is hingedly connected to the top support 43 and the bottom support 40 at both ends, respectively. The hinge shaft 42 is connected with the third connecting rod 47 through interference fit, and synchronous motion is achieved between them. The hinge shaft 42 is coupled with the top support 43 through the connecting rod assembly, achieving the change of the height and angle of the electric tail wing. When the tail wing is in the fully open state, the third connecting rod 47 contacts the bottom support at this time, and the mechanical structure limiting realizes self-locking of the hinge mechanism, ensuring the opening height and angle of the tail wing. Under the action of external force, the tail wing is not easy to shake, and the support stability of the four connecting rod mechanism to the tail wing plate is further improved. When the tail wing is in the closed state, the third connecting rod 47 contacts the bottom support again, and the hinge mechanism is self-locked again, ensuring that the tail wing can also withstand a certain external force in the closed state. In addition, an anti-collision pad is provided on the bottom support, which can effectively reduce the noise generated when the third connecting rod 47 contacts the bottom support 40.

The liquid stored in the mounting sink 21 can be discharged through the drain pipe 23.

[0033] The hinge shaft 42 is fixedly connected with one end of the driving shaft 37 through the connecting pipe 44.

[0034] The signal acquisition circuit board 7 is electrically connected with the wire harness assembly 30.

[0035] After the ECU sends a command, the motor 32 starts to rotate. A primary worm 33 is pressed and mounted on the output shaft of the motor 32 and rotates synchronously with the motor 32. The primary worm 33 meshes with a primary worm gear 34, and the rotation of the primary worm 33 drives the rotation of the primary worm gear 34. The primary worm gear 34 is pressed and mounted on a secondary worm 35, and the rotation of the primary worm gear 34 drives the synchronous rotation of the secondary worm 35. The secondary worm 35 meshes with a secondary worm gear 36, and the rotation of the secondary worm 35 drives the rotation of the secondary worm gear 36. The secondary worm gear 36 is in interference fit with a driving shaft 37, and the rotation of the secondary worm gear 36 drives the synchronous rotation of the driving shaft 37. A magnetic ring 39 is in interference fit on the driving shaft 37, and the rotation of the driving shaft 37 drives the synchronous rotation of the magnetic ring 39. A motor magnetic ring 6 is integrated at the tail end of the motor 32 and corresponds to the signal acquisition circuit board 7, which can sense the magnetic pole signal change in the rotation process of the motor 32 and output the direction and number of turns of the motor 32 to the ECU. By recording and feeding back the number of turns and direction of the motor 32, the rotation of the motor 32 can be accurately controlled, and the rotation angle and direction of the driving shaft 37 can be controlled, finally realizing the accurate control of the opening angle of the tail wing and achieving the stepless adjustment of the opening angle.

In the intermediate stepless angle opening position, the primary worm 33, the primary worm gear 34, the secondary worm 35, and the secondary worm gear 36 in the driving unit 3 realize two-stage worm gear transmission self-locking, ensuring the reliability and stability of the intermediate arbitrary opening angle.
