摘要： An imaging lens module (1, 2, 3, 4) includes a lens element (11, 41, 51, 61) having an optical axis, a lens carrier (12, 22, 32, 42, 52, 62) and a variable through hole assembly (13, 43). The lens carrier accommodates the lens element and sequentially includes an object-side portion (121, 421, 521, 621), an image-side portion (122, 322, 422) and a tubular portion (123, 423). The object-side portion configured for light entering the imaging lens module forms a minimum opening (OP) of the lens carrier. The variable through hole assembly is disposed on the object-side portion and includes rotatable blades (132, 432) rotatably disposed about the optical axis and configured to form a through hole (TH) with a variable size. Moreover, the object-side portion further has a guiding structure (1212, 4212) guiding the movement of the rotatable blades and located further away from the optical axis than the minimum opening. Moreover, the object-side portion and the image-side portion form an air sleeve (AS) therebetween, and the air sleeve is located further away from the optical axis than the tubular portion.

The variable aperture module includes a light blocking sheet set, a fixed element, a movable element, and an annular light blocking portion. The light blocking sheet set includes at least two light blocking sheets, wherein the at least two light blocking sheets are mutually stacked along a circumferential direction surrounding the optical axis to form a variable aperture opening. The fixed element has a sidewall structure. The annular light blocking portion surrounds the optical axis to form a fixed aperture opening.

摘要： A variable aperture module (10) includes a blade assembly (12) including movable blades (121), a positioning element (13) including positioning structures (131) and a driving part (14) including a rotation element (141). The movable blades (121) are disposed around an optical axis (OA) to form a light passable hole (HL) with adjustable size for different hole size states and each have an inner surface (1211) to define the contour of the light passable hole (HL) in each hole size state. The positioning structures (131) correspond to the movable blades (121). The rotation element (141) is rotatable with respect to the positioning element (13) and is configured to rotate the movable blades (121) to adjust a size of the light passable hole (HL). There are matte structures (15) disposed on each inner surface (1211). Each matte structure (15) is single structure extending towards the optical axis (OA), such that at least part of the contour of the light passable hole (HL) has an undulating shape at least in several hole size states.

摘要： A variable aperture (1), a camera module (20), and an electronic device (100) are provided. The variable aperture (1) includes a base (12), a fixed plate (13), a rotation plate (14), a plurality of blades (15), a first SMA wire (16), and a second SMA wire (17). The fixed plate (13) is fixedly connected to the base (12), and the rotation plate (14) is rotatively connected to the base (12) and disposed around the fixed plate (13). The plurality of blades (15) are annularly distributed and enclose an aperture hole (11), and each of the blades (15) is rotatively connected to the fixed plate (13) and slidably connected to the rotation plate (14). One end of each of the first SMA wire (16) and the second SMA wire (17) is connected to the base (12), the other end is connected to the rotation plate (14). The first SMA wire (16) or the second SMA wire (17) is configured to shrink when power is on, to drive the rotation plate (14) to rotate relative to the fixed plate (13). Each of the blades (15) rotates relative to the fixed plate (13) and slides relative to the rotation plate (14), so that an aperture of the aperture hole (11) changes. A direction in which the first SMA wire (16) shrinks to drive the rotation plate (14) to rotate is opposite to a direction in which the second SMA wire (17) shrinks to drive the rotation plate (14) to rotate. Aperture adjustment precision of the aperture hole (11) of the variable aperture (1) is high.

摘要： [Problem] To provide a diaphragm device that can be downsized in a radius direction although a diameter of an aperture stop can be accurately set.
[Solution] The diaphragm device includes a bottom plate 12a that is formed in an annular shape on which an aperture M for an optical path is formed, a plurality of diaphragm blades 13 that are attached to the bottom plate 12a in a rotatable manner, a blade rotation member that rotates the diaphragm blades 13 with respect to the bottom plate 12a, and biasing members 16 that bias the respective diaphragm blades 13 to one side in a rotation direction of the multiple diaphragm blades 13 with respect to the bottom plate 12a. The blade rotation member has cam grooves 14a that cause the diaphragm blades 13 to rotate with respect to the bottom plate 12a to change a diameter of an aperture stop. The diaphragm blades 13 each have a cam protrusion 19 that is fixed thereto and engaged with the cam groove 14a. The diaphragm blades 13 each have a biasing protrusion 20 that protrudes from a surface thereof, is fixed thereto, and is engaged with the biasing member 16. The cam protrusion 19 is in contact with a side surface of the cam groove 14a by biasing force of the biasing member 16.
