Claim Text:
1. A driving mechanism of an actuator for a vehicle door double lock system, comprising: a motor having a shaft; a first gear fixed to the shaft to rotate with the shaft; a second gear meshed with the first gear, the second gear comprising a non-tooth part formed thereon; a third gear meshed with the second gear, the third gear being rotatable between a first position, a second position and a third position; a projection formed on the third gear and rotates with the third gear; a first stop arranged on a rotation path of the projection for cooperating with the projection to stop rotation of the third gear; wherein the motor is configured to rotate the first gear, which in turn rotates the second gear, which in turn drives the third gear; and when the second gear rotates to a position where the non-tooth part of the second gear corresponds to the third gear, the third gear is in the second position and the projection is spaced from the first stop by an angle, and when the second gear continues rotating to a position where the non-tooth part of the second gear is completely separated from the third gear, the second gear is re-meshed with the third gear and drives the third gear to rotate until the third gear is in the third position and the projection on the third gear is in contact with the first stop.
