Abstract: The disclosure provides an optical driving mechanism, including a frame body, a holding member, a plate coil and a magnet. The holding member is movably disposed in the frame body and configured to hold an optical element. The plate coil is disposed on the holding member. The magnet is disposed on the frame body and corresponds to the plate coil. The plate coil acts with the magnet to generate an electromagnetic force to drive the holding member and the optical element to move along an optical axis of the optical element relative to the frame body.

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.
Abstract translation: 本发明提供了一种基于VCA的透镜驱动装置。 通过提供改进的OIS线圈结构，用于感测可能由用户的手抖动引起的顶部的磁体的移动的磁感应元件可以尽可能远离OIS线圈。 因此，OIS线圈的磁场对磁感应元件的影响减小。 在一个实施例中，OIS线圈尺寸减小以减小OIS线圈对放置在其旁边的磁感应元件的影响。 在另一个实施例中，OIS线圈具有单侧缩进，并且磁感应元件放置在OIS线圈的凹槽之下或旁边。

Abstract: A driving mechanism for moving an optical element is provided, including a movable portion, a fixed portion, a driving assembly, and a first resilient element. The movable portion is for connecting the optical element. The movable portion is movable relative to the fixed portion. The driving assembly drives the movable portion to move relative to the fixed portion. The first resilient element has a board structure. The movable portion is movably connected to the fixed portion via the first resilient element. The fixed portion includes a connection surface, a restricting surface, and a recessed portion. At least a portion of the first resilient element is disposed on the connection surface. The restricting surface contacts and restricts the movable portion. The recessed portion is located between the connection surface and the restricting surface, wherein the recessed portion is lower than the connection surface and the restricting surface.
