Title: ULTRA-THIN SHAFT-SHIFT MID-SET-TYPE OPTICAL ANTI-SHAKE VOICE COIL MOTOR
Abstract:
Disclosed is an ultra-thin shaft-shift mid-set-type optical anti-shake voice coil motor. The ultra-thin shaft-shift mid-set-type optical anti-shake voice coil motor relates to the technology field of voice coil motors, solving problems of excessive power consumption of the shaft-shift mid-set-type optical anti-shake voice coil motor, a complicated motor structure and being not suitable for an ultra-thin portable photography device, an insufficient linearity area, and focusing performance being influenced and the closest focal distance being limited. The motor comprises a pedestal (1), a lens carrier (2) and a shell (3), wherein the pedestal (1) is provided with three or more pedestal bosses (11), each pedestal boss (11) is connected to an outer side wall of the lens carrier (2) via a set of spring sheets (4); and the shell (3) is mounted on the pedestal (1), an inner side wall of the shell (3) is provided with three or more groups of magnets (5), each group of magnet (5) comprises a single-sided bipolar magnet, or each group of magnet (5) is composed of two magnets, and magnetic pole orientation of each magnet is opposite to each other, thereby effectively reducing a focusing power consumption, prolonging the endurance of an image device and reducing an impact of motor heating power on components around the motor.
