Abstract

A driving mechanism is used to drive an optical assembly, and the driving mechanism includes an outer frame module, a bearing part and an electromagnetic driving assembly. The carrying part is arranged in the outer frame module for accommodating the optical components, wherein the carrying part has a side wall part, and a through hole is formed in the side wall part. The electromagnetic driving assembly includes a first magnetic assembly and a second magnetic assembly, wherein the first magnetic assembly is arranged on the bearing part and exposed inside the bearing part through a hole. The second magnetic component is connected with the frame module and corresponds to the first magnetic component, and is used for driving the carrier to move relative to the frame module.

Description

technical field [0001] The present invention relates to a driving mechanism, in particular to a driving mechanism capable of moving an optical component by electromagnetic force. Background technique [0002] With the rapid development of communication technology, camera lens modules have been widely used in portable electronic devices such as mobile phones and tablet computers. However, in order to improve the quality of photos taken by the camera lens module, it is usually equipped with an electromagnetic drive mechanism to adjust the position of the optical lens to achieve the functions of autofocus and / or zoom. shows a clear image. [0003] Since the camera lens module has tended to be miniaturized in recent years, it is extremely necessary to reduce the volume of its driving mechanism, but this often leads to the problem that the mechanical strength of the driving mechanism is insufficient and easily damaged. In view of this, how to reduce the size of the aforemention...
