    • A power actuator for a door lock device comprising an electric motor driving a worm gear, a gear wheel driven by the worm gear, a handling lever driven by an arcuate projection on the gear wheel and a locking arm rotated by the handling lever. The wheel gear has a peripheral groove with a portion of reduced width for supporting opposite ends of an elongate coil spring; which is compressed in a direction corresponding to the rotation of the gear wheel. An arcuate segment projects axially from the gear wheel. The opposite ends of the arcuate segment and the handling lever is shaped to provide point contact with the handling lever upon initial engagement and surface contact as the arcuate projection moves the handling lever to the locking and unlocking position. A contact is disposed on a base plate; and contacts on the handling lever slidably engage the contacts on the base plate to detect the locking and unlocking position of the handling lever.
    • 一种用于门锁装置的动力致动器,包括驱动蜗轮的电动马达,由蜗轮驱动的齿轮,由齿轮上的弧形突起驱动的操纵杆和由操纵杆旋转的锁定臂。 轮齿轮具有一个具有减小宽度部分的周边槽,用于支撑细长螺旋弹簧的相对端; 其在与齿轮的旋转相对应的方向上被压缩。 弧形段从齿轮轴向突出。 当弧形突起将操纵杆移动到锁定和解锁位置时,弓形段和操纵杆的相对端成形为在初始接合和表面接触时提供与操纵杆的点接触。 接触件设置在基板上; 并且操纵杆上的触点可滑动地接合在底板上的触点,以检测操纵杆的锁定和解锁位置。
