Title
(EN) Driving assembly, camera module and electronic equipment with shooting function
(ZH) 驱动组件、相机模块和具有拍摄功能的电子设备
Abstract
(EN) The invention relates to a driving assembly, a camera module and electronic equipment with a shooting function. The driving assembly is used for driving a moving part to move, and the driving assemblycomprises a motor for providing driving force, a transmission part connected with the output end of the motor and an execution part movably matched with the transmission part. The moving part can beconnected to the transmission part in a sliding mode, the moving part and the execution part are arranged in a spaced mode, and the driving assembly further comprises a shape memory alloy wire used for connecting the moving part and the execution part. The motor can drive the transmission part to enable the execution part to move in a first direction, so that the shape memory alloy wire drives themoving part to move in the first direction, and the shape memory alloy wire enables the moving part to move relative to the execution part in the first direction under the control of an external electric signal. When the driving assembly is used for the camera module, the driving assembly can be used for driving a movable lens assembly to move along the optical axis, and therefore zooming and automatic focusing can be conveniently achieved.
(ZH) 本发明涉及一种驱动组件、相机模块和具有拍摄功能的电子设备,用于驱动移动部件运动,驱动组件包括提供驱动力的电机、与所述电机的输出端连接的传动部以及与所述传动部可动配合的执行部;所述移动部件能够滑动连接于所述传动部并与所述执行部间隔设置,所述驱动组件还包括用于连接所述移动部件和所述执行部的形状记忆合金线;所述电机能够驱动所述传动部使所述执行部沿第一方向移动,从而通过所述形状记忆合金线带动所述移动部件沿所述第一方向运动,所述形状记忆合金线在外部电信号的控制下使所述移动部件沿所述第一方向相对所述执行部移动。当该驱动组件用于相机模块时,能够用于驱动可动镜片组件沿光轴运动,从而能够便于实现变焦和自动对焦。
