Abstract

The invention relates to an actuating motor device which is provided with a supporting structure, a movable assembly and a memory alloy actuator; the movable assembly is assembled on the supporting structure and obtains a first axial direction for guiding the moving direction of the movable assembly, the movable assembly is provided with two or more moving parts, and the moving parts move in a graded mode in the first axial direction; the memory alloy actuator is used for driving the moving parts of the movable assembly to move in the first axial direction. By designing the structural system of the movable assembly, the moving parts in the movable assembly move in a graded mode in the first axial direction, the size is small, work is stable and reliable, and a large focusing stroke is obtained. The actuating motor device is used for manufacturing a camera assembly, can drive a lens to move up and down, achieves the automatic focusing function of the lens, achieves the grading movementfocusing, increases the focusing function of the lens, is light and miniaturized in product structure, reduces the manufacturing cost, is simple, convenient and precise in control, and is suitable forpopularization and application.

Description

technical field [0001] The invention relates to the technical field of actuating motor devices, in particular to actuating motor devices driven by memory alloy (SMA) materials, especially for driving camera lens elements. Background technique [0002] In recent years, with the explosive popularity of portable information terminals sometimes referred to as PDAs (Portable Digital Assistants) and mobile phones, more and more devices incorporate compact digital camera devices employing image sensors. When such a digital camera device is miniaturized using an image sensor with a relatively small image acquisition area, its optical system (including one or more lenses) needs to be miniaturized accordingly. [0003] To enable focus and zoom, some type of drive must be contained within the small space of such compact cameras to drive the camera lens elements along the optical axis. Because camera lens elements are relatively small, the drive must be able to provide precise drive ov...
