Title:
CORE-DRIVEN-TYPE AUTOFOCUS CAMERA MODULE
Document Type and Number:
WIPO Patent Application WO/2024/040692
Kind Code:
A1
Abstract:
The present disclosure relates to a core-driven-type autofocus camera module, which resolves problems such as soft circuit boards of existing core-driven-type autofocus cameras shifting easily when moving, occupying a large space and having poor heat dissipation. The module comprises a housing, a lens arranged on the housing, a circuit board arranged in the housing, an image sensor, a position sensor, and a driving mechanism. When in use, the position sensor is used for detecting displacement of the image sensor so as to implement autofocusing. When a circuit board body moves upwards, a deformation supporting part is restored to provide a downward restoring force for a supporting connecting part. When the circuit board body moves downwards, the deformation supporting part is restored to provide an upward restoring force for the supporting connecting part. When the camera module is not working, the restoring force resets a movable seat to reduce the impact of the movable seat on other components and abnormal sound caused by external vibrations. In addition, when the circuit board body moves up and down, same is not prone to tilting, the positioning is accurate, and the occupied space is small. Furthermore, heat dissipation efficiency of the image sensor is increased.
