Title:
IRIS DIAPHRAGM DEVICE AND CAMERA MODULE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2023/093839
Kind Code:
A1
Abstract:
The present invention provides an iris diaphragm device and a camera module. The iris diaphragm device at least comprises a driving mechanism (22), a transmission mechanism (23), and a blade assembly (24); the transmission mechanism (23) is transmittingly connected to the blade assembly (24); and the driving mechanism (22) drives the transmission mechanism (23) to drive the blade assembly (24) to form a blade through hole (252) having a variable aperture. Or, the iris diaphragm device at least comprises a driving assembly (20a), a transmission mechanism (40a), and a blade assembly (30a); the driving assembly (20a) comprises a driving component (21a), a return component (22a), a fixing portion (23a), and a moving component (24a), the driving component (21a) and the return component (22a) driving the transmission mechanism (40a) by means of the moving component (24a) to reciprocatively rotate; or the driving assembly (20a) comprises a driving component (21a), a return component (22a), a first guide mechanism (25a), and a second guide mechanism (26a), the driving component (21a) being supported by the first guide mechanism (25a) to telescopically move, the return component (22a) being supported by the second guide mechanism (26a) to telescopically move, and the driving component (21a) and the return component (22a) driving the transmission mechanism (40a) to reciprocatively rotate. The camera module comprises the iris diaphragm device.
