摘要： This application provides a variable aperture, a camera module, and an electronic device. The variable aperture includes a fixing base, a rotating support, a mover, a stator, and a plurality of blades. The rotating support is disposed on an inner side of the fixing base. In this way, on one hand, the rotating support does not interfere with components on an outer side of the fixing base, thereby ensuring accuracy of a rotation angle of the rotating support in a rotating process; and on another hand, the components on the outer side of the fixing base may be disposed close to the fixing base, and the components are arranged more compactly, thereby facilitating miniaturization of the variable aperture. In addition, the mover is fixedly connected to an outer peripheral side surface of the rotating support, and the stator is disposed facing the mover. In this way, on one hand, stacking of the mover and the stator in a thickness direction of the camera module is avoided; and on another hand, the mover, the stator, the fixing base, and the rotating support may be arranged more compactly.

摘要： A light pass aperture module (110, 110', 110"), in order along a central axis (CA), includes a blade assembly (111) and a cap (112, 112', 112"). The blade assembly (111) includes a plurality of blades (111a, 111b). The blades form a light pass aperture (100), and the light pass aperture (100) is variable in size with the central axis as a center. The cap (112, 112', 112") covers the blade assembly (111). The cap (112, 112', 112") has a through hole (112a), and the through hole (112a) is disposed corresponding to the light pass aperture (100). The cap (112, 112', 112") includes a surface level down structure (112b, 112b'). The surface level down structure (112b,112b') is disposed corresponding to one of the blades (111a, 111b), and the surface level down structure (112b,112b') is closer to the one blade (111a, 111b) than the through hole (112a).

摘要： An imaging lens assembly includes a plurality of optical lens elements, a single-piece-formed light blocking sheet and a lens barrel. The lens barrel has a circular light-passing hole corresponding to the plurality of optical lens elements and the single-piece-formed light blocking sheet. The single-piece-formed light blocking sheet has a central aperture corresponding to the lens barrel and the plurality of optical lens elements. A maximum aperture diameter is defined by the central aperture. The single-piece-formed light blocking sheet comprises a plurality of light blocking structures surrounding and disposed adjacent to the central aperture. A minimum inner radius of the central aperture is defined near the center of each of the light blocking structures.

摘要： An imaging lens (100) with an optical axis (101) includes a lens carrier (110) and a variable through hole assembly (120). The lens carrier (110) is configured for at least one lens element (1202) to be disposed therein, and the lens carrier (110) includes a mount structure (112). The variable through hole assembly (120) includes a plurality of movable blades (121) and a rotatable element (122). The movable blades (121) movably and together surround the optical axis (101) to form a through hole (TH), and a size of the through hole (TH) is variable by movement of the movable blades (121). The rotatable element (122) is connected to the movable blades (121), and the rotatable element (122) moves the movable blades (121) to vary the size of the through hole (TH). At least one of the movable blades (121) and the rotatable element (122) of the variable through hole assembly (120) is disposed on the mount structure (112).

摘要： A controllable aperture stop (2) includes a light pass portion (21), a fixed portion (23), a driving part (25) and rollable elements (270). The light pass portion (21) includes movable blades (ASB) together surrounding a light pass aperture (210). The fixed portion (23) has shaft structures (2310) corresponding to the movable blades (ASB). The driving part (25) includes a rotatable element (251), a magnet (253) and a coil (255). The magnet (253) is disposed on the rotatable element (251). The magnet (253) and the coil (255) are to drive the rotatable element (251) to rotate around the light pass aperture (210) for driving the movable blades (ASB) to rotate relative to the shaft structures (2310). The rollable elements (270) are disposed between the fixed portion (23) and the rotatable element (251) and arranged around the light pass aperture (210), so the rotatable element (251) is rotatable relative to the fixed portion (23).

摘要： This application relates to the field of terminal device technologies, and in particular, to an aperture, a camera module, and an electronic device. The aperture includes a base, a carrier base, a driving part, a resilient sheet, and a plurality of blades. A first optical hole for light to pass through is formed on the base. Each blade is hinged on the base, and the plurality of blades are distributed around the first optical hole, so that a light entry hole coaxial with the first optical hole is formed among the plurality of blades. The carrier base is connected to the base by using the resilient sheet, and the carrier base is configured to drive each blade to rotate relative to the base to change a size of the light entry hole. The driving part is configured to drive the carrier base to rotate by using an axis line of the first optical hole as a rotation axis. The driving part in the aperture may be set as a miniature driver, and a structure of the resilient sheet is also relatively light and thin. The driving part, cooperating with the resilient sheet, may provide driving force for driving size adjustment of the aperture, which is further beneficial to realizing a small size structure of the aperture. Therefore, the aperture may be applied to a camera module of a miniature electronic device, to meet a photographing requirement of the miniature electronic device.
