Abstract

The invention discloses a rotary actuating structure, an actuator and a camera module. The rotary actuating structure comprises a base plate with with a power supply circuit arranged in an end surface, a rotating plate movably arranged on the same end face of the base plate and the power supply circuit, and a first SMA wire with one end connected with the rotating plate. The other end of the firstSMA wire is connected with a first output port corresponding to the power supply circuit, and the first SMA wire is used for closing contraction to drive the rotating plate to rotate relative to thebase plate. According to the rotary actuating structure, the rotation stroke can be easy to control.

Description

technical field [0001] The invention relates to the technical field of camera devices, in particular to a rotary actuation structure, an actuator and a camera module. Background technique [0002] An actuating device (actuating device) is a commonly used driving mechanism in the electronic field, and can be used to drive a lens unit to achieve anti-shake or focusing. SMA refers to shape memory alloy, which is a kind of driving element in the actuating device. SMA is a material composed of two or more metal elements having a shape memory effect (SME) through thermoelasticity and martensitic phase transformation and its inversion. SMA can be deformed at a lower temperature, can be contracted and deformed after being heated by electricity, and returns to the shape before deformation after cooling, so as to realize electronically controllable shrinkage. At present, the actuating structure on the actuating device is usually electrically connected by ordinary wiring or printed c...
