Abstract: Provided is a driver assembly for driving a moving component. The driver assembly includes: a motor; a transmission portion; and an execution portion; and a shape memory alloy wire connecting the moving component with the execution portion. The moving component is slidably connected to the transmission portion and spaced apart from the execution portion. The motor can drive the transmission portion to lead the execution portion to move along a first direction, in such a manner that the moving component is driven by the shape memory alloy wire to move along the first direction. The shape memory alloy wire is configured to drive the moving component to move along the first direction relative to the execution portion under an external electrical signal. When being applied in the camera module, the driver assembly can drive the movable lens assembly to move along an optical axis, facilitating the zooming and autofocus.

Abstract: A zoom lens group is provided and includes a cover, a first magnetic device and at least two lenses. The cover includes an installation cavity, and the first magnetic device is connected to the cover. Each of the at least two lenses is movably arranged in the installation cavity and provided with a second magnetic device. The first magnetic device is configured to attract the second magnetic device to calibrate each of the at least two lenses, in such a manner that axes of the at least two lenses coincide with each other. The zoom lens group can calibrate the camera lenses, thereby increasing precision of the zoom lens group and improving the imaging effect.

Abstract: Provided is a camera module, including: a lens group including a lens barrel and a camera lens; and a driver assembly configured to drive the camera lens to move and including a magnetic portion. The camera lens includes a magnetic matching portion. The magnetic portion and the magnetic matching portion are respectively located at two ends of a side wall of the lens barrel in a thickness direction, and are connectable to each other through magnetic attraction, in such a manner that the camera lens is driven by the driver assembly to move along the optical axis of the camera lens. In this way, the side wall of the lens barrel is free of a through hole, so that light is prevented from entering the lens barrel via the through hole, thereby prolonging the lifetime of the camera module and improving the image-capturing effect.

Abstract: The present disclosure provides a lens module. The lens module includes: a base; a lens carrier movably installed to the base; a driver configured to connect the base with the lens carrier in a transmission way and to drive the lens carrier to partially expand out of or retract into the base; and a magnet assembly provided correspondingly at the base and the lens carrier. The lens carrier can be in press fit with an inner wall of the base under a magnetic force of the magnet assembly, so that the lens carrier can maintain relatively fixed with the base in a direction perpendicular to a telescoping direction during expansion and retraction of the lens carrier. Therefore, the lens carrier and the base can always maintain precise coaxiality in the telescoping direction.

Abstract: The present disclosure provides an actuating device and a method for controlling an SMA actuator wire. The actuating device includes: a first support structure and a second support structure that are spaced from each other to define a movement space; a movable element received in the movement space; an SMA actuator wire configured to drive the movable element to move in the movement space; a detection element configured to detect movement information; and a control element configured to adjust a power state of the SMA actuator wire based on the movement information in such a manner that the SMA actuator wire is in a loose state after the SMA actuator wire drives the movable element to be fixed to the second support structure. This can alleviate the technical problem in the related art that the SMA actuator wire is prone to failure when the lens is suffering collision or falling.
