Title:
IRIS DIAPHRAGM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/231935
Kind Code:
A1
Abstract:
An iris diaphragm (301) and an electronic device, relating to the technical field of terminal devices. The iris diaphragm (301) comprises: a base (3a), a rotating ring (2) and a plurality of blades (1), wherein the rotating ring (2) is rotationally connected to the base (3a); the plurality of blades (1) are arranged on the side of the rotating ring (2) away from the base (3a); the plurality of blades (1) are annularly distributed and jointly define a diaphragm hole (4); tail ends of the blades (1) are used for controlling the aperture size of the diaphragm hole (4); each blade (1) is rotationally connected to the base (3a) and is slidably connected to the rotating ring (2); positions where the blades (1) are rotationally connected to the base (3a) are rotation pivots for the rotation of the blades (1); positions where the blades (1) are slidably connected to the rotating ring (2) are driving positions for the sliding of the blades (1); and the rotation pivots are located between the driving positions and the diaphragm hole (4). Compared with providing the driving positions between the rotation pivots and the diaphragm hole (4), when there is an error in an actual movement displacement of the rotating ring (2), a ratio of magnification errors in linear displacements of actual rotation of the ends of the blades (1) is reduced, thereby increasing f-stop F.
