Abstract: An auto-focus driving structure for installing a lens has an optical axis. The auto-focus driving structure comprises a main body, a lens retainer, and a driving unit. The lens retainer is movably disposed in the main body. The driving unit includes a coil circuit board and a magnetic group. The coil circuit board has a plurality of printed coils. The plurality of printed coils corresponds to the position of the magnetic group, thus the lens retainer can be selectively moved with respect to a bottom portion of the main body through the driving unit.

Abstract translation: 用于安装透镜的自动聚焦驱动结构具有光轴。 自动对焦驱动结构包括主体，透镜保持器和驱动单元。 透镜保持件可移动地设置在主体中。 驱动单元包括线圈电路板和磁性组。 线圈电路板具有多个印刷线圈。 多个印刷线圈对应于磁性体的位置，因此可以通过驱动单元相对于主体的底部选择性地移动透镜保持器。
