Optical element driving device, camera and portable electronic device

An optical element driving device, comprising:

• 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 alloy from being broken,
• wherein the fixing component and the movable component are connected by the first shape memory alloy and the second shape memory alloy;
• wherein the safety mechanism device is coupled to the fixing component or the movable component by a force applied by an elastic component, and the applied force is larger than a force generated by shape recovering of any one of the first shape memory alloy and the second shape memory alloy when being energized.
