下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参照图1-6，一种用于摄像镜头的防抖装置，包括：外壳40、设置于所述外壳40内的定子组件30、设置于所述定子组件30内的动子组件20及与所述动子组件20插接的底座10；所述定子组件30包括框架32及镶嵌于所述框架32内的FPC板31，所述框架32的一周的内壁上均开设有镶嵌槽，所述镶嵌槽中嵌合有FPC板31，且框架32内设置有嵌埋电路连接件，所述电路连接件包括第一电路连接321及与所述第一电路连接321相邻设置的第二电路连接322，所述第一电路连接321与第二电路连接322均用于连接对向设置的FPC板31，其中框架32一相对的对角处开设有卡槽33，通过框架32内设置有电路连接件，起到向FPC板31供电，而FPC板31内设置有OIS线圈，与磁石23相互作用，最终实现OIS防抖功能，通过设置独立的四个FPC板31，方便将OIS线圈层数加以增设，可实现较大推力，OIS防抖效果好，能载动较大镜头。四线圈中对向的两线圈互为串联结构，具体是通过FPC两侧端的各焊盘与框架32内设的电路连接结构相连接，通过电路连接结构为桥接实现对向两线圈之间的电路导通。且还可将柔性FPC板31改装成硬性PCB板材质创造了有利条件，直接在硬性PCB电路板上涂以电路层数，制作工艺相对直接简单、成 本较低。
进一步的，所述动子组件20包括磁石支架22、设置于磁石支架22内的绕线载体24、设置于绕线载体24上端的第一弹簧件21、设置于所述绕线载体24下端的第二弹簧件25，所述磁石支架22包括方形结构的连接杆221及设置于所述连接杆221四角处的固定座222，且所述连接杆221内嵌埋有加强筋结构。所述固定座222相对的两面上分别开设有镶嵌槽，每相邻的两个固定座222之间镶嵌有磁石23，所述磁石23两端设置有镶嵌面，所述镶嵌面与所述镶嵌槽相匹配。为圆筒状的绕线载体24上缠绕有环状线圈241，且该绕线载体24沿外周一圈固接有多个固定连接台243，每两个所述固定连接台243对称设置于绕线载体24上。所述第一弹簧件21包括两个相对设置的第一弹簧连接杆211与第二弹簧连接杆211，所述第一弹簧连接杆211与第二弹簧连接杆211构成一圆形结构且与绕线载体24相对应。所述第一弹簧连接杆211与第二弹簧连接杆211的结构相同，且第一弹簧连接杆211的两端上分别固接有第一固定板。所述第一固定板上固接有第一弹簧链2112，所述第一弹簧链2112上固接有第一角固定板2111，所述第一角固定板2111固定于固定座222上。第一弹簧连接杆211与第二弹簧连接杆211上的第一角固定板2111构成一正方形结构。第一弹簧连接杆211与第二弹簧连接杆211均通过第一固定板固定于绕线载体24的固定连接台243上端面上。所述第二弹簧件25包括一环形杆252及均匀分布固定于所述环形杆252上的第二固定板，所述环形杆252通过第二固定板固定于绕线载体24的固定连接台243的下端面上。所述环形杆252上均匀固定有四个第二固定板，每个所述第二固定板上固接有第二弹簧链254。所述第二弹簧链254上固接有固定件251，所述固定件251固定于固定座222的下端面上。通过向绕线载体24上的环状线圈241附加电流，则在Z轴光轴方向(前方)上电磁力就开始起作用，但经第一弹簧件21和第二弹簧件25的弹性按比例性地进行变位(即弹簧丝伸缩)后，就会作用向Z轴光轴方向。因此，透镜的位置即向前方移动的距离是在电磁力和弹性力相平衡的点上。据此，根据附加在驱动线圈上的电流量，就可决定作为绕线载体24的移动量。而且当环状线圈241通入电流后，环状线圈241与驱动磁石之间就会产生电磁力，根据弗莱明左手法则，由于电磁力的作用驱使绕线载体24沿镜头光轴方向(即Z轴)作直线移动，绕线载体最终停留于环状线圈241与磁石23之间产生的电磁力与第一弹簧件21和第二弹簧件25的弹性力的合力达到相均衡状态时的位置点。通过向环状线圈241通入既定的电流，可控制使绕线载体24移动至目标位置，从而达到自动调焦的目的。
通过向FPC板31内的四个线圈通入既定的电流，通电的四个线圈与对向的四个磁石23相作用产生电磁力，根据左手弗兰明法则，驱使动子组件20向X\Y轴向作防抖补正驱动。整个OIS防抖装置靠四根悬丝11得以支撑。动子组件20与定子组件30及底座之间，在X\Y\Z轴向上保留有一定空间距离，不相接触。
进一步的，环形杆252上的固定件251呈方形设置且与固定座222一一相对应。
进一步的，所述底座10包括基座、嵌埋于所述基座内的连接线路结构14、设置于所述基座上的位置传感器12及设置于基座四角处的悬丝11，基座上设置有两个位置传感器12，一个设置于底座10X轴向，用于检测X轴向的磁气变化，另一个设置于底座10Y轴向，用于检测Y轴向的磁气强弱变化。两个位置的位置传感器12与设于磁石支架22的磁石23在Z轴光轴方向上呈对向位置关系。通过位置传感器12感应在X-Y轴向随磁石支架22一起偏向抖动位移的磁石23所产生的磁场强弱变化，从而检测出X-Y轴向镜头的位置偏移距离，由此在实际拍摄过程中对X-Y轴向镜头抖动位移基于位置传感器12的时时受到反馈控制(即闭环控制)。根据反馈控制信号，施加反向驱动力加以位置偏差补正，即实现防抖的功能和目的，避免了拍摄模糊的情形。
进一步的，所述基座一相对的边角处分别固接有连接柱，基座另一相对的边角处分别固接有卡接条13，所述卡接条13与框架32上的卡槽33相对应。
进一步的，所述基座为一方形板，且该基座中间开设有一通孔，所述通孔与绕线载体24及磁石支架22中的让位孔分别相对应。
进一步的，所述悬丝11一端延伸至基座的连接线路结构14上，另一端沿竖直方向穿过固定座222延伸至第一弹簧件21的第一角固定板2111中。
进一步的，所述绕线载体24、磁石支架22及磁石23之间间隙装配，使得绕线载体24不会受到摩擦阻力，顺畅在Z轴光轴方向作对焦驱动。
进一步的，所述动子组件20与定子组件30之间间隙配合，为该装置在X\Y轴向的防抖驱动保留一定位移空间距离。
进一步的，所述框架32与磁石支架22之间的四角处设置有阻尼胶，通过该阻尼胶使得该装置在X/Y轴向具有缓冲防震及稳定驱动的效果。
进一步的，所述磁石支架22四角处靠近底座10的一面上涂覆有阻尼胶，通过该阻尼胶，对该装置X/Y轴向位震颤进一步起到缓冲防震的作用，通电状态下使驱动更具稳定性，整个防抖驱动线性进一步提升。
进一步的，绕线载体24与磁石支架22之间设置有阻尼胶，所述阻尼胶使得绕 线载体24在X/Y轴向位震颤起到缓冲防震的作用，通电状态下使驱动更具稳定性，对防抖驱动和对焦驱动的良好线性提升都具有促进作用。
这里说明的设备数量和处理规模是用来简化本发明的说明的，对本发明的应用、修改和变化对本领域的技术人员来说是显而易见的。
尽管本发明的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
