Aperture device, imaging device, action camera, and movable object

Abstract

An aperture device (100), a shooting device, a motion camera and a movable object, the aperture device (100) comprises a blade support (10), a plurality of blade assemblies (20), a driving assembly (30) and an elastic assembly (40), the plurality of blade assemblies (20) are arranged around an optical axis, and one side of the blade assembly (20) is connected with the blade support (10), and the blade assembly (20) comprises a guide part (21). The driving assembly (30) comprises a driving part (31) corresponding to the plurality of guide parts (21), for driving the plurality of blade assemblies (20) to rotate along a preset direction through the guide part (21). The elastic assembly (40) is connected with the blade support (10), the elastic assembly (40) comprises a plurality of elastic members (41), and at least part of the plurality of elastic members (41) are commonly formed into an integral forming structure, and the elastic assembly (40) is used for abutting against the plurality of blade assemblies (20), so that the edge of the guide part (21) always abuts against the driving part (31) through the elastic force of the elastic member (41).
