    • An actuator assembly is for a lock including a handle, a latch, a retractor for retracting the latch when the handle rotates, and a lock member displaceable between locked and unlocked positions, which either releasably couples the handle with the retractor or releasably prevents handle rotation. The actuator includes a motor having a shaft rotatable about an axis and a coupler spring disposed about the axis and having a first end coupled with the lock member and a second end. A drive member is coupled or integrally formed with the motor shaft and has a helical drive surface threadably engaged with the coupler spring second end, such that rotation of the shaft displaces the coupler spring along the axis to move the lock member between the locked and unlocked positions. Preferably, the drive member includes a spring coupled with the motor shaft and threadably engaged with the coupler spring.
    • 致动器组件用于包括手柄,闩锁,当手柄旋转时用于收回闩锁的收缩器的锁定器,以及可在锁定位置和解锁位置之间移动的锁定构件,锁定构件可释放地将手柄与牵开器联接或可释放地防止手柄旋转 。 致动器包括具有可绕轴线旋转的轴的马达以及围绕轴线设置的联接器弹簧,联接器弹簧具有与锁定构件联接的第一端和第二端。 驱动构件与马达轴联接或一体形成并且具有与联接器弹簧第二端螺纹接合的螺旋驱动表面,使得轴的旋转使联接器弹簧沿轴线移动,以将锁定构件在锁定和解锁之间移动 位置。 优选地,驱动构件包括与马达轴联接并与联接器弹簧螺纹接合的弹簧。
