Title:
OPTICAL ANTI-SHAKE COMPONENT
Document Type and Number:
WIPO Patent Application WO/2021/047608
Kind Code:
A1
Abstract:
An optical anti-shake component (100), comprising an annular first base (10), a second base (20) disposed on the inner side of the first base (10) at an interval and used for mounting a lens, and three shape memory alloy wires (36, 37, 38). Each shape memory alloy wire (36, 37, 38) comprises a first fixed end (31) fixed on the first base (10), a first extension section (32) extending from the first fixed end (31) to the direction of the second base (20), a second fixed end (33) fixed at the second base (20), a second extension section (34) extending from the second fixed end (33) to the direction of the first base (10), and a third fixed end (35) connected to the second extension section (34) and fixed at the first base (10); the first fixed ends (31) and the third fixed ends (35) are disposed at intervals, the included angle between two driving forces generated by two adjacent shape memory alloy wires (36, 37, 38) to the second base (20) is smaller than 180° when the two adjacent shape memory alloy wires are powered on, and reverse extension lines of the driving forces generated by the shape memory alloy wires (36, 37, 38) are gathered at one point. The optical anti-shake component (100) has the advantages of simple structure and low production cost.
