Title:
ELASTIC SHEET DESIGN METHOD AND ELASTIC SHEET, SMA ASSEMBLY, LENS MODULE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/233418
Kind Code:
A1
Abstract:
The present application provides an elastic sheet design method and an elastic sheet, a shape memory alloy (SMA) assembly, a lens module, and an electronic device. The SMA assembly comprises a fixing member, an elastic sheet, and an SMA wire; one end of the SMA wire is connected to the fixing member, and the other end of the SMA wire is connected to the elastic sheet; the elastic sheet comprises an elastic sheet main body and at least one elastic sheet cantilever, wherein the elastic sheet cantilever is connected to the elastic sheet main body and extends along the outer edge of the elastic sheet main body, the elastic sheet cantilever is connected to the fixing member at a predetermined position of an extension portion, and the at least one elastic sheet cantilever is in an axial symmetry or a 90° rotational symmetry. The technical solution can reduce or eliminate the mechanical crosstalks of the elastic sheet in the SMA assembly, and improve the optical image stabilization performance.
