Title:
VARIABLE APERTURE STRUCTURE, CAMERA MODULE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/005812
Kind Code:
A1
Abstract:
A variable aperture structure (10), a camera module, and an electronic device. The variable aperture structure (10) comprises: a fixed part (100), a moving part (200), a driving part, a blade assembly (300), and a locking structure. The moving part (200) is sleeved on the fixed part (100); the blade assembly (300) is disposed on the moving part (200) ±, and the blade assembly (300) is used to form a light inlet hole through which light passes; the driving part is used to drive the moving part (200) to rotate relative to the fixed part (100), and the rotation of the moving part (200) can drive the blade assembly (300) to rotate so as to adjust the size of the light inlet hole; and the locking structure is used to lock the moving part (200) on the fixed part (100) when the moving part (200) is rotated to a set position. The driving part can drive the moving part (200) to the fixed part (100) for locking when the driving part stops working, so that the moving part (200) will not autorotate after the driving part stops working, and the aperture of the light inlet hole can then be kept at the largest position, which facilitates subsequent photographing.
