Patent attributes
A lens module includes a lens, a barrel, a holder and a driving mechanism. The barrel is configured for receiving the lens. The holder is configured for receiving the barrel therein. The driving mechanism includes a first lever and a first piezoelectric device. The first lever includes a fixed end and a moving end and a connecting portion interconnected between the fixed end and the moving end. The fixed end of the first lever is pivotedly mounted in the holder. The moving end of the first lever is configured for driving the barrel to move. The first piezoelectric device is arranged between the connecting portion and the holder. The first piezoelectric device is extendable and contractible along an optical axis of the lens so as to control movement of the barrel along the optical axis relative to the holder.
