Abstract: A driving device includes a motor and a gearbox. The gearbox includes a first sun gear, first planetary gears surrounding and engaged with the first sun gear, and a first internal gear ring surrounding and engaged with the first planetary gears. The first sun gear is coaxially fixed to a rotary shaft of the motor. Meshing planes of the first sun gear and the first planetary gears are slanted with respect to the rotary shaft. Each of the first planetary gears is subjected to an externally-exerted first force and exerts a transverse component of force toward the rotary shaft on the first sun gear. The motor structure of the driving device is simplified, which makes the driving device have a more compact structure, lighter weight and lower cost.

Abstract: An actuator for a vehicle door lock mechanism has a motor, a first gear, a second gear and a third gear. The motor has a shaft to which the first gear is connected. The motor rotates the first gear, which in turn drives the second gear and the third gear. A non-tooth part is formed on the second gear. A projection is formed on the third gear. Stops are arranged for stopping rotation of the third gear. When the second gear rotates to a position where the non-tooth part corresponds to the third gear, the projection is spaced from one stop by an angle. When the second gear rotates further, the gears re-mesh and the third gear rotates till the projection contacts the stop.

Abstract translation: 用于车门锁定机构的致动器具有马达，第一齿轮，第二齿轮和第三齿轮。 电动机具有连接第一档的轴。 马达旋转第一齿轮，继而驱动第二齿轮和第三齿轮。 在第二齿轮上形成非齿部。 在第三档上形成突起。 停止装置用于停止第三档的旋转。 当第二齿轮旋转到非齿部对应于第三齿轮的位置时，突起与一个止挡件间隔一定角度。 当第二齿轮进一步旋转时，齿轮重新啮合，第三齿轮旋转直到突出部接触止动件。
