Abstract
An optical element driving device is provided, which includes: a fixing component as a base; an original position being a neutral position with respect to the fixing component; a movable component movable in two reversed directions with respect to the original position; a first shape memory alloy energized to move the movable component towards one of the two reversed directions; a second shape memory alloy energized to move the movable component towards the other one of the two reversed directions; and a safety mechanism device arranged between the fixing component and the movable component, for preventing the first shape memory alloy and the second shape memory from being broken. The fixing component and the movable component are connected by the first shape memory alloy and the second shape memory alloy. The optical element driving device can avoid damage of shape memory alloy and thus have high reliability.
