  • Patent number: 11513312
    Abstract: A lens drive device, including a lens support, a coil winded at a periphery of the lens support; a screening can is covered outside the lens support; a driving magnets is respectively provided on opposite two inner sidewalls of the screening can; a Printed Circuit Board board (PCB board) is provided on a sidewall at another side of the screening can; a Hall chip is provided on the PCB board; a Hall magnet back gasket and a Hall magnet are provided at corresponding positions of the lens support; and the PCB board and the Hall chip thereon and the Hall magnet form a lens position detection unit. Since the driving magnets and the Hall magnet are not hindered to each other in a configuration structure, no obstacle is produced to assembly work, and the further miniaturization and thinning of the lens drive device also become possible.
