  • Patent number: 10884215
    Abstract: Provided are a lens driving device, a camera device, and an electronic apparatus that are capable of smoothly guiding a lens support. A lens driving device (10) includes a lens support (22) configured to support a lens, a frame member (30) surrounding a periphery of the lens support (22), and a plurality of guiding mechanisms (52a to 52a) configured to guide the lens support (22) relative to the frame member (30) in a freely movable manner. Each of the plurality of guiding mechanisms (52a to 52d) includes a first guiding portion (62a to 62d) formed in the frame member (30), a second guiding portion (64a to 64d) formed in the lens support (22), and balls (24a to 24d) arranged between the first guiding portion (62a to 62d) and the second guiding portion (64a to 64d). The first guiding portion (62b) is formed with use of a first frame member (30a) and a second frame member (30b) that are separate members.

  • Patent number: 8970973
    Abstract: A lens actuating device includes a fixed member, an adjustable member, a driving unit and a movable support unit. The adjustable member is movably disposed in the fixed member along an optical axis, and has a lens module disposed therein. The driving unit is disposed between the fixed member and the adjustable member to provide a driving force for the adjustable member. The movable support unit is disposed at one side of the adjustable member opposite to the driving unit and has a first guiding structure formed on an inner side of the fixed member parallel to the optical axis, a second guiding structure, and a plurality of rolling members. The rolling members are configured into two rows and are disposed between the first and second guiding structures to fix the seconding guiding structure such that the displacement of the adjustable member is constrained along the optical axis.

  • Patent number: 7652835
    Abstract: An optical device. A drive moving assembly includes a lens module and a drive coil. The drive coil surrounds the lens module and provides a central axis parallel to an optical axis of the lens module. A drive stator includes a housing, a magnetic member, and a yoke. The lens module is movably disposed in the housing. The magnetic member surrounds the drive coil and includes an opening. The yoke interacts with the magnetic member, generating a magnetic field. The magnetic member, yoke, and drive coil interact to move the drive moving assembly parallel to the optical axis. A brake coil is disposed in the opening. A braking resilient member is connected between the drive stator and the brake coil and disposed in the opening. The brake coil interacts with the magnetic member, yoke, and braking resilient member and detachably abuts the drive moving assembly.
