Patent ID: 8218062

Claim:
A photographing module, at least including a lens unit, an electrically controlled actuator, an elastic member, and a photo sensor, the lens unit at least comprising one lens element; the electrically controlled actuator at least comprising: a fixed element, a movable element positioned within the fixed element, having, a hollow central portion around an optical axis, and connected to the lens unit, and an electrical unit positioned around the outside of the movable element; the elastic member at least comprising: a fixed portion, a movable portion, an elastic portion linked between the fixed portion and the movable portion, and a pair of power supply terminals linked to the fixed portion; and the photo sensor being positioned on an image side of the photographing module and connected to the fixed member of the electrically controlled actuator, wherein the elastic member is positioned between the fixed element and the movable element of the actuator, the elastic member electrically communicates with the electrical unit of the actuator, the fixed portion of the elastic member is connected to the fixed element of the actuator, the movable portion of the elastic member is connected to the movable element of the actuator, and the fixed portion is integrally formed with the elastic portion as one piece such that the thickness of the fixed portion in a direction of optical axis of the lens unit is greater than that of the elastic portion; and wherein when power from, an external power source is input to the electrical unit through the pair of power supply terminals, an axial displacement of the movable element of the actuator is generated, which enables the lens unit to move linearly along the optical axis leading to the movement of the movable portion of the elastic member that enables the elastic portion to have a linear displacement.
