摘要： A lens displacement mechanism using shaped memory alloy (SMA) applied to an auto-focusing lens module is disclosed. The lens displacement mechanism comprising at least one SMA wire. Two opposite ends of the SMA wire are fixed and a longitudinal mid-point of an intermediate movable portion between the two opposite ends is tightened and is fixed on a corresponding hook disposed on an outer edge of the lens so that the intermediate movable portion is tightened between the two opposite ends. When the SMA wire is heated, the intermediate movable portion contracts to pull the hook of the lens for driving the lens to move and slide along with an optical axis so as to achieve auto-focus control. The present lens displacement mechanism is simple in structure and reflow process. Therefore, the present displacement mechanism is suitable to be used in portable camera or mobile phone or PDA, which needs to be small and have easily mass production by SMT.
