  • Patent number: 9575331
    Abstract: A lens driving device is based on a Voice Coil Actuator (VCA) structure and provides the auto-focusing and optical image stabilization (OIS) functions. These two functions can be realized by a common magnet scheme, or a separate magnet scheme. Also, the present invention provides an improved structure for the lens driving device to enhance the function of OIS thereof. By arranging a magnetic enhancement device below the OIS coils in the lens driving device, the magnetic driving force of the OIS coils and magnetic induction of the Hall sensors, if present, can be enhanced, and the magnetic sensitivity thereof may be also improved.

  • Patent number: 9366840
    Abstract: A method for manufacturing a base structure of lens-focusing mechanism first prepares a conductive member having at least two conductive parts, interconnection part, contacts and two conductive pins. The conductive parts have proximity ends separated and staggered to each other. An insulating base is formed by injection molding and encapsulates the conductive member wherein the conductive pins, the interconnection part and the contacts are exposed out of the insulating base. The interconnection part is cut and then a spring member is mounted to the insulating base and electrically connected to the conductive pins through the contacts. The present invention can solve the problem of difficulty in assembling conductive pins and connecting the spring member for the insulating base. The conductive member is arranged within the insulating base such that plastic material can be saved, the flatness, the stability and the anti-damage ability of base can be enhanced.

  • Publication number: 20160131923
    Abstract: The present invention provides some configurations of flexible connections jointly or integrally formed with a movable part and/or a fixed part of a lens module. The flexible connections may move the movable part along an optical axis direction and/or directions perpendicular to the optical axis. The configuration and material of the flexible connections provide an enhanced strength bearing plastic deformation, and hence increasing the structure strength of the lens module. The formation of the flexible connections with the movable part and/or the fixed part with one mold-injection process can reduce parts of the lens module and simply its manufacturing process.

  • Patent number: 9304325
    Abstract: The present invention provides a VCA-based lens driving device. By way of giving an improved OIS coil structure, a magnetic induction element used to sense movement of magnets atop which maybe cause from a user's hand shaking can be placed as far away from OIS coils as possible. The impact of the magnet field of the OIS coil on the magnetic induction element is thus reduced. In one embodiment, the OIS coil is down-sized to reduce the influence of the OIS coil on the magnetic induction element placed beside it. In another embodiment, the OIS coil has a one-sided indention and the magnetic induction element is placed below/or beside the indention of the OIS coil.
