Patent number: 7824115Abstract: An exemplary camera module includes a lens mount, a lens unit, a magnet unit, a printed circuit board (PCB)-based Rogowski coil and a blade spring. The PCB-based Rogowski coil is fixed around the lens unit. The PCB-based Rogowski coil establishes an induced magnetic field when an electric current is applied thereto. The induced magnetic field interacts with the magnet unit to generate a magnetic force moving the lens unit telescopically. The blade spring includes a plurality of ribs. Each rib includes a moveable end connected with the lens unit and an opposite fixed end. The moveable end moves together with the lens unit with respect to the fixed end to cause the ribs to distort and generate an elastic force. The lens unit stops at a focal position when the magnetic force and the elastic force come to a balance.Type: GrantFiled: July 22, 2008Date of Patent: November 2, 2010Assignees: Fu Zhun Precision Industry (Shen Zhen) Co., Ltd., Foxconn Technology Co., Ltd.Inventors: Wun-Chang Shih, Ching-Hsing Huang, Cheng-Fa Weng, Jen-Te Wang, Huai-Chao You, Da-Yi Wen, Biao Wang, Yun-Ming Hu

Patent number: 7782559Abstract: A camera module includes a lens unit, a magnet, a stator and an elastic element. The stator includes an upper coil seat with an upper coil wound therearound and a lower coil seat with a lower coil wound therearound. The upper and the lower coils establish an induced magnetic field when electric currents are applied thereto. The induced magnetic field interacts with the magnet to generate a magnetic force driving the lens unit into a telescopic movement. The elastic element includes a plurality of ribs. Each rib includes a fixed end connected with the stator and an opposite movable end. The moveable end moves together with the lens unit with respect to the fixed end to cause the ribs to deform and generate an elastic force. The lens unit stops at a focal position when the magnetic force and the elastic force come to a balance.Type: GrantFiled: August 12, 2008Date of Patent: August 24, 2010Assignees: Fu Zhun Precision Industry (Shen Zhen) Co., Lt.d, Foxconn Technology Co., Ltd.Inventors: Ching-Hsing Huang, Cheng-Fa Weng, Jen-Te Wang, Huai-Chao You, Da-Yi Wen

Patent number: 7729605Abstract: An auto-focusing camera includes a stator (20), a rotor (30) rotatably disposed in the stator, and a lens unit (40) received in the rotor. The stator includes a stator core (23) and coils (25) winding on the stator core. The rotor is a permanent magnet (32) securely mounted around the lens unit. The lens unit forms three ears (414) at a bottom thereof, and a wave-shaped surface (220) is formed on a top of an inner, bottom flange (22) of the stator. The ears abut the wave-shaped surface. The ears of the lens unit move along the wave-shaped surface during rotation of the rotor and the lens mount, and thus the lens unit moves telescopically along an axial direction thereof.Type: GrantFiled: December 29, 2007Date of Patent: June 1, 2010Assignees: Fu Zhun Precision Industry (Shen Zhen) Co., Ltd., Foxconn Technology Co., Ltd.Inventors: Cheng-Fa Weng, Huai-Chao You, Jen-Te Wang, Ching-Hsing Huang
