Abstract

The present disclosure relates to a lens assembly, comprising a lens module and a lens driving mechanism for driving the lens module to move relative to an image sensor, the lens driving mechanism comprising: a base fixedly mounted on the image sensor; a bearing structure which is used for mounting the lens module; a bearing structure which is mounted on the base in a sliding manner through the first sliding rail; a second sliding rail, wherein the extension direction of the second sliding rail is different from the extension direction of the first sliding rail, and the lens module is slidably mounted on the bearing structure through the second sliding rail; a first electromagnetic generating device which is used for generating electromagnetic induction and driving the bearing structure to move along the first sliding rail; and a second electromagnetic generating device which is used for generating electromagnetic induction to drive the lens module to move along the second sliding rail. The lens module always linearly moves along the slide rail and is supported by the slide rail, so that the lens module moves more stably and has higher movement precision, the optical axis of the lens is ensured not to deflect, and the imaging definition is improved.

Description

technical field [0001] The present disclosure relates to the field of lens technology, in particular, to a lens assembly. Background technique [0002] An optical system is a system used for imaging or optical information processing, which can be applied in various fields, for example, it can be applied to the lens of mobile phone camera, camera or projection technology. As the application of optical systems becomes more and more extensive, users are more pursuing optical systems with high-definition imaging. During the use of the lens, hand-held equipment or other external actions may cause the shooting equipment to shake. When the shutter speed is slow, shake reduces the sharpness of the image. At the same time, for the sensor chip that detects whether the image is in focus through the lens, shaking will also slow down the focusing speed. Therefore, in order to minimize the negative impact of shaking on taking pictures, a lens drive mechanism is introduced to counteract...
