The operation of the electric spoiler drive apparatus of the present disclosure will be described in detail with reference to fig. 7 and 8.

Fig. 7 shows the first state (the driving device is in the closed position) of the electric spoiler drive device 100 according to the present disclosure, wherein the first gear 205 of the motor device 20 is engaged with the second gear 302 of the transmission device 30 to transmit the power of the motor device 20 to the transmission device 30.

The worm gear portion 303 in the transmission 30 meshes with a gear/worm wheel 402 on the output shaft assembly 40 to transfer the motion of the transmission 30 to the output shaft assembly 40, which is output to the spoiler via an output shaft 401 in the output shaft assembly 40 to drive the spoiler to move into position.

The electronic sensor records the number of revolutions of the motor, so that the whole electric spoiler driving device and the spoiler can be stopped at any required position.

Before the trigger lever 403 triggers the first switch portion 50 or the second switch portion 70, the trigger lever 403 rotates together with the driving lever 405 under the action of the limit spring, and after the trigger lever 403 triggers the first switch portion 50 or the second switch portion 70, as shown in fig. 8, the motor device 20 is stopped, so that the output shaft 401 stops rotating, and the spoiler is stopped at the maximum position or the closed position.

Considering the time delay of the vehicle control system and the inertia of the entire transmission system, when the trigger lever 403 triggers the first switching portion 50 or the second switching portion 70, the electric spoiler drive 100 does not stop immediately, and therefore the driving lever 405 continues to rotate, and the trigger lever 403 and the driving lever 405 separate from each other, thereby preventing the switching portion from being crushed by the trigger lever 403.

When the electric spoiler drive 100 moves in the reverse direction, the trigger bar 403 and the driving bar 405 return to the initial positions again by the first and

second hooks

4041 and 4042 of the stopper spring, so that the position of the electric spoiler drive 100 can be accurately indicated.
