Abstract

The invention provides an aperture switching device, a photographic device thereof and electronic equipment. The aperture switching device comprises a base and a shell, a first light hole is formed inthe base corresponding to an aperture, a second light hole is formed in the shell corresponding to the aperture, the shell covers the base, the base is provided with a rotary connecting part and a sliding groove, and the clamping part is a driving power supply input terminal and is fixed on the base; two ends of a shape memory alloy wire are respectively and correspondingly connected with the clamping parts; a movable bump is connected with the shape memory alloy wire; the elastic part is fixed at the rotary connecting part and is propped against the movable bump; one end part of the opticalaperture switching unit is mounted on the rotary connecting part, a switching groove is formed in the end part, and the switching groove is mounted on the movable bump. Through driving of the shape memory metal wire, the size of the lens light inlet aperture can be changed to adjust the amount of light entering the imaging system.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to an aperture switching device, a photographing device including the same, and electronic equipment. Background technique [0002] With the increasing popularity of portable electronic devices such as smartphones and tablet computers, these electronic devices may include camera functions, for example, a voice coil motor-type aperture switcher for a mobile phone camera module is a relatively common one. [0003] However, the driving structure of the aperture switcher of the camera module of the voice coil motor type mobile phone is complicated, and the size of the product is not easy to be reduced. The structure of the aperture switch needs to be integrated with the structure of the camera motor, and cannot be an independent functional component, and it can be selected and assembled according to different modules. The electromagnetic components in the switcher are prone to elect...
