Abstract

The invention discloses a variable aperture device, a camera module and electronic equipment, the variable aperture device comprises a fixing assembly, an aperture assembly and a driving assembly, the fixing assembly comprises an aperture carrier, the aperture carrier is provided with a through hole and a shell, the aperture assembly comprises a first aperture piece, a second aperture piece and at least one adjusting rod, the aperture assembly is adjustably installed on the aperture carrier, and the driving assembly drives the first aperture piece to rotate. One end of the adjusting rod is rotatably connected to the top surface of the shell, the other end of the adjusting rod is connected to the first aperture piece and / or the second aperture piece, and the driving assembly drives the adjusting rod to rotate so as to guide the first aperture piece and the second aperture piece to move, so that the aperture area of the aperture assembly is adjusted. Therefore, the aperture assembly is switched between the large aperture state and the small aperture state, and is suitable for the variable aperture with two-stage change or multi-stage accurate change.

Description

technical field [0001] The invention relates to an aperture device, in particular to a variable aperture device, a camera module and electronic equipment. Background technique [0002] At present, the aperture of the mobile phone camera module can be divided into two types: variable and immutable. The aperture device is an important part of the camera module. As an indispensable element of the optical system, it is set on the lens in the form of a structural component when the lens is assembled. on / in. The area of ​​the aperture directly affects the amount of light entering the camera module, which also affects the brightness and depth of field of the image. When the area of ​​the aperture is large, the camera module has a larger amount of light entering, so that the formed image has high brightness and a good background blurring effect. The resulting image details are sharper. [0003] Due to the limited installation space of the camera module in electronic equipment suc...
