ELECTROMAGNETIC DRIVE MODULE AND LENS DRIVING DEVICE USING THE SAME

PROBLEM TO BE SOLVED: To provide an electromagnetic driving assembly that is arranged so as to supply power to drive and move components (for example, a lens assembly) in an electronic product, and a downsized electromagnetic module.SOLUTION: An electromagnetic drive module includes: a frame 20 installed so as to surround a main axis M; a magnet 30 that is installed on the frame 20, and has a front side surface and a rear side surface opposite to the front side surface, and in which the front side surface is arranged so as to separate from the main axis M compared to the rear side surface, and the area of the front side surface is smaller than the area of the rear side surface; a base arranged adjacently to the frame 20; and an OIS drive coil installed on the base so as to be opposite to the magnet 30, and arranged so as to pass current. The electromagnetic drive module is driven so that the frame 20 moves along a direction vertical to the main shaft M.SELECTED DRAWING: Figure 2 【課題】動力を提供して、電子製品内の構成要素（例えば、レンズアセンブリ）を駆動して移動させるように配置された電磁駆動アセンブリを提供し、且つ小型化した電磁駆動モジュールを提供する。【解決手段】主軸Ｍを囲んで設置されるフレーム２０、フレーム２０の上に設置され、前側面および前側面と対向する後側面を含み、前側面は後側面に比べ、主軸Ｍから離れて配置され、且つ前側面の面積は、後側面の面積より小さい磁石３０、フレーム２０に隣接して配置されるベース、およびＯＩＳ駆動コイルは、磁石３０に対向してベースの上に設置され、電流を通過させるように配置され、フレーム２０が主軸Ｍに垂直な方向に沿って移動するように駆動する電磁駆動モジュール。【選択図】図２
