Abstract

The invention provides a driving mechanism for carrying an optical element, which includes a fixed module, a movable module, a driving module and an elastic element arranged between the fixed module and the movable module. The driving module can drive the movable module to rotate around a first rotation axis relative to the fixed module. The elastic element includes a first connection part connected to the movable module, a second connection part connected to the fixed module, a first string part connected to the first connection part, and a first buffer part connected to the first string part. The first string portion is disposed on the first rotation axis, and its long axis direction is parallel to the first rotation axis. The first buffer part has a corrugated structure.

Description

Technical field [0001] The present invention relates to a drive mechanism. More specifically, the present invention relates to a drive mechanism having an elastic element. Background technique [0002] With the development of technology, many electronic devices (such as smartphones or digital cameras) have functions or video. The use of these electronic devices is increasingly common and developed towards facilitating and lightweight design directions to provide more choices. [0003] The electronic device having a photographic or video function is provided with an elastic element and a drive module to rotate in a suspension optical element and drive an optical element, thereby achieving the purpose of shaking compensation. However, when the optical element is rotated, the elastic element tends to generate a stress concentration, thereby causing breakage and damage to the elastic element. Therefore, how to solve the problem of the aforementioned problem into an important issue. ...
