Abstract

The embodiment of the invention discloses an aperture device, an image capturing mechanism and electronic equipment. The electronic device can be a mobile phone, a tablet personal computer, a handheld computer, an interphone, a POS machine, an automobile data recorder, a wearable device, a virtual reality device, a vehicle-mounted front part and other terminal products with screens. The aperture device provided by the embodiment of the invention comprises a light through hole, a shielding part and a heating part, the shielding part is provided with a thermal deformation area, and the heating part is used for heating the thermal deformation area; the thermal deformation area is made of a shape memory material, the shape of the thermal deformation area can be changed under the thermal driving effect of the heating part and after the thermal driving effect is eliminated, the shielding area of the shielding part on the light through hole is changed through the shape change of the thermal deformation area, and therefore the aperture value is changed. The aperture device provided by the embodiment of the invention is simple in structure, light in weight and low in power consumption, and can meet the requirements of portability, light weight, battery durability and the like of the electronic equipment when being applied to an image capturing mechanism of the electronic equipment.

Description

technical field [0001] The present application relates to the technical field of electronic products, and in particular to an aperture device, which can be applied to electronic equipment equipped with an image-taking mechanism. Background technique [0002] With the rapid development of electronic products, the functional requirements of the imaging mechanism of electronic products are getting higher and higher. Allowing the aperture value of the aperture device of the imaging mechanism to be adjustable is a powerful means to enhance the competitiveness of electronic products. [0003] At present, the aperture device of the imaging mechanism on the market mainly drives a group of blades to rotate in a plane through a motor to change the blocking area of ​​the blades on the light hole, thereby changing the aperture value. This kind of aperture device has complex structure, heavy weight, and high power consumption, which cannot meet the requirements of portable, light weight...
