Optical element driving mechanism

The utility model provides an optical element driving mechanism. The optical element driving mechanism comprises a fixed part, a movable part, a driving assembly and a sensing assembly. The fixing part is provided with a main shaft and comprises an outer frame and a base. The base and the outer frame are arranged along the spindle. The movable part moves relative to the fixed part and can bear anoptical element with an optical axis. The driving assembly drives the movable part to move relative to the fixed part. The sensing assembly senses the movement condition of the movable part relative to the fixed part. The sensing assembly comprises a sensor. The sensor is arranged on the base. 本公开提供一种光学元件驱动机构。光学元件驱动机构包括一固定部、一活动部、一驱动组件以及一感测组件。固定部具有一主轴，包括一外框以及一底座。底座与外框沿着主轴排列。活动部相对于固定部运动，并可承载具有一光轴的一光学元件。驱动组件驱动活动部相对于固定部运动。感测组件感测活动部相对于固定部的运动状况。感测组件包括一感测器。感测器设置于底座。
