Description
本发明涉及光学成像装置,特别涉及一镜头驱动组件和摄像模组。
随着移动电子设备的普及,被应用于移动电子设备的用于帮助使用者获取影像的摄像模组的相关技术得到了迅猛的发展和进步。目前在市场中,消费者对于配置于移动电子设备(例如,智能手机)的摄像模组的功能要求越来越高和多样化,例如要求摄像模组防抖功能,以期获得更佳的成像效果。
在使用移动电子设备进行摄像时,由于人体在正常情况下存在的一定频率的生理震颤和由于运动产生的抖动,会导致摄像效果下降,尤其是对于普通消费者而言,其缺乏专业的训练而更容易导致抖动且抖动幅度更大。因此移动电子设备通常配有防抖马达(即驱动组件),以驱动光学镜头移动实现防抖功能。
随着摄像模组的成像质量要求越来越高,光学镜头的体积和重量越来越大,对驱动组件的驱动力要求也越来越高,防抖马达的占用体积随着镜头的增大而相应的增加。而当前移动电子设备的轻薄化的发展趋势对摄像模组的体积也有很大的限制,导致摄像模组逐渐地无法满足电子设备的配置需要。换句话说,在光学镜头向更大体积、更大重量发展的趋势下,驱动组件所能提供的驱动力却难以相应地增加。在驱动力受限的前提下,镜头越重,驱动组件能够驱动光学镜头移动的行程越短,影响防抖能力。另外,光学镜头越重,驱动组件能够驱动光学镜头移动的速度也越慢,光学镜头到达预定的补偿位置的时间也越长,这也会影响防抖效果。

依本发明的说明书附图之附图1A至图18,依本发明的一较佳实施例的一摄像模组在接下来的描述中将被揭露和被阐述,其中所述摄像模组包括一镜头组件20、一感光组件30以及一镜头驱动组件40,所述镜头组件20包括一光学镜头21,所述光学镜头21被设置于所述感光组件30的感光路径,并且所述镜头驱动组件40被设置能够驱动所述光学镜头21平移而实现所述摄像模组的防抖,和驱动所述光学镜头21沿着所述摄像模组的光轴方向运动而实现所述摄像模组的对焦。
优选地,参考附图1A、图1B和图14,所述摄像模组进一步包括一芯片驱动组件10,其中所述感光组件30被可驱动地设置于所述芯片驱动组件10,以由所述芯片驱动组件10驱动所述感光组件30运动而实现所述摄像模组的防抖。
换言之,在本发明的所述摄像模组的这个具体示例中,所述芯片驱动组件10被设置能够驱动所述感光组件30运动,如此镜头驱动组件40被设置能够驱动所述光学镜头21运动,如此大幅度地提高所述摄像模组的防抖效果。
参考附图3A和图3B,所述镜头驱动组件40包括一镜头防抖载体410、一镜头对焦内框420以及一镜头对焦外框430,其中所述光学镜头21被设置于所述镜头防抖载体410,所述镜头防抖载体410被可驱动地连接于所述镜头对焦内框420,所述镜头对焦内框420被可驱动地连接于所述镜头对焦外框430,其中所述镜头对焦外框430能够被直接或者间接地设置于所述感光组件30,以由所述镜头驱动组件40保持所述光学镜头21于所述感光组件30的感光路径,或者所述镜头对焦外框430能够被直接或者间接地设置于所述芯片驱动组件10,以由所述镜头驱动组件40保持所述光学镜头21于所述感光组件30的感光路径。
当所述镜头对焦内框420保持不动,并且所述镜头防抖载体410被驱动做相对于所述镜头对焦内框420的运动时,所述镜头防抖载体410能够带动所述光学镜头21在垂直于所述摄像模组的光轴的方向做相对于所述感光组件30的运动,以实现所述摄像模组的防抖,即,所述光学镜头21能够被平移。换言之,所述镜头防抖载体410能够形成所述镜头驱动组件40的一镜头防抖部41的可动部分,从而所述镜头防抖载体410形成所述镜头防抖部41的一镜头防抖可动单元411,相应地,所述镜头对焦内框420能够形成所述镜头驱动组件40的所述镜头防抖部41的固定部分,从而所述镜头对焦内框420形成所述镜头防抖部41的一镜头防抖固定单元412。
当所述镜头对焦外框430保持不动,并且所述镜头对焦内框420被驱动做相对于所述镜头对焦外框430的运动时,所述镜头对焦内框420通过所述镜头防抖载体410带动所述光学镜头21在所述摄像模组的光轴方向运动,以实现所述摄像模组的对焦。换言之,所述镜头对焦内框420能够形成所述镜头驱动组件40的一镜头对焦部42的可动部分,从而所述镜头对焦内框420形成所述镜头对焦部42的一镜头对焦可动单元421,相应地,所述镜头对焦外框430能够形成所述镜头对焦部42的固定部分,从而所述镜头对焦外框430形成所述镜头对焦部42的一镜头对焦固定单元422。
也就是说,所述镜头驱动组件40包括镜头防抖部41和所述镜头对焦部42。所述镜头防抖部41包括所述镜头防抖可动单元411和所述镜头防抖固定单元412,所述光学镜头21被设置于所述镜头防抖可动单元411,当所述镜头防抖可动单元411被驱动在垂直于所述摄像模组的光轴的方向做相对于所述镜头防抖固定单元412的运动,所述摄像模组实现防抖。所述镜头对焦部42包括所述镜头对焦可动单元421和所述镜头对焦固定单元422,当所述镜头对焦可动单元421被驱动在所述摄像模组的光轴的方向做相对于所述镜头对焦固定单元422的运动时,所述摄像模组实现对焦。
参考附图3A、图3B、图7至图12,所述镜头防抖可动单元411包括所述镜头防抖载体410,所述镜头防抖固定单元412包括所述镜头对焦内框420,所述镜头对焦可动单元421包括所述镜头对焦内框420,所述镜头对焦固定单元422包括所述镜头对焦外框430,即,所述镜头对焦内框420同时作为所述镜头防抖部41和所述镜头对焦部42的一部分,如此所述镜头驱动组件40具有紧凑的结构,从而有利于减小所述摄像模组的整体体积。
继续参考附图3A、图3B、图7至图12,所述镜头防抖部41进一步包括一镜头防抖驱动单元413,其中所述镜头防抖驱动单元413包括至少一镜头防抖磁石4131和至少一镜头防抖线圈4132,所述镜头防抖磁石4131被设置于所述镜头防抖载体410,所述镜头防抖线圈4132被设置于所述镜头对焦内框420,并且所述镜头防抖磁石4131的位置和所述镜头防抖线圈4132的位置相对应,如此当所述镜头防抖线圈4132被通入电流而使所述镜头防抖线圈4132产生磁场时,所述镜头防抖线圈4132的磁场和所述镜头防抖磁石4131的磁场相互作用,以驱动所述镜头防抖载体410带动所述光学镜头21沿着垂直于所述摄像模组的光轴的方向平移,从而实现所述摄像模组的防抖。
值得一提的是,对于所述镜头防抖载体410来说,无论是在所述摄像模组实现防抖的过程中,还是在所述摄像模组实现对焦的过程中,所述镜头防抖载体410均需要被改变位置;对于所述镜头对焦内框420来说,只有在所述摄像模组实现对焦的过程中,所述镜头对焦内框420才需要被改变位置,而在所述摄像模组实现防抖的过程中,所述镜头对焦内框420保持不动。基于此,本发明的所述摄像模组通过将所述镜头防抖磁石4131设置于所述镜头防抖载体410和将所述镜头防抖线圈4132设置于所述镜头对焦内框420的方式,能够简化所述摄像模组的电路设计并保证所述摄像模组在被使用过程中的可靠性。
尽管如此,在本发明的所述摄像模组的其他示例中,所述镜头防抖驱动单元413的所述镜头防抖磁石4131可以被设置于所述镜头对焦内框420,相应地,所述镜头防抖线圈4132可以被设置于所述镜头防抖载体410。
进一步地,所述镜头防抖载体410具有一载体顶面4101、相对于所述载体顶面4101的一载体底面4102以及自所述载体顶面4101延伸至所述载体底面4102的一载体通道4103,其中所述镜头防抖载体410环绕于所述光学镜头21,以允许所述光学镜头21被设置于所述镜头防抖载体410的所述载体通道4103。优选地,所述光学镜头21的外壁和所述镜头防抖载体410的用于形成所述载体通道4103的内壁被贴装,以固定所述光学镜头21于所述镜头防抖载体410。
所述镜头对焦内框420包括一镜头对焦内框顶部4201,其中所述镜头对焦内框顶部4201具有一内框顶面42011、相对于所述内框顶面42011的一内框底面42012以及自所述内框顶面42011延伸至所述内框底面42012的一内框通道42013。所述镜头防抖载体410以所述镜头对焦内框顶部4201的所述内框底面42012和所述镜头防抖载体410的所述载体顶面4101相对应的方式被悬持于所述镜头对焦内框420的底部,并且所述镜头防抖载体410被驱动能够做相对于所述镜头对焦内框顶部4201的运动。所述光学镜头21被可活动地保持在所述镜头对焦内框顶部4201的所述内框通道42013,以使所述镜头对焦内框顶部4201环绕于所述光学镜头21的四周。
可以理解的是,所述镜头对焦内框顶部4201的用于界定所述内框通道42013的内壁和所述光学镜头21的外壁之间具有间隙,以允许所述光学镜头21平移而实现所述摄像模组的防抖。
所述镜头防抖驱动单元413的所述镜头防抖磁石4131被设置于所述镜头防抖载体410的所述载体顶面4101,所述镜头防抖线圈4132被设置于所述镜头对焦内框顶部4201的所述内框底面42012,如此:一方面,所述镜头防抖磁石4131和所述镜头防抖线圈4132相邻,以确保所述镜头防抖线圈4132在被通电时产生的磁场和所述镜头防抖磁石4131的磁场能够相互作用,从而提高足够的驱动力驱动所述镜头防抖载体410带动所述光学镜头21在垂直于所述摄像模组的光轴的方向平移,以实现所述摄像模组的防抖;另一方面,所述镜头防抖磁石4131和所述镜头防抖线圈4132能够被保持在所述镜头防抖载体410和所述镜头对焦内框顶部4201之间,以使所述镜头防抖磁石4131和所述镜头防抖线圈4132远离所述感光组件30和/或所述芯片驱动组件10,从而减少所述镜头防抖磁石4131向所述感光组件30的方向外溢的磁场对所述感光组件30的线路板、感光元件以及所述芯片驱动组件10的磁干扰。
优选地,所述镜头防抖载体410进一步具有至少一防抖磁石凹槽4104,所述防抖磁石凹槽4104自所述载体顶面4101向所述载体底面4102方向延伸,其中所述镜头防抖磁石4131被嵌入所述镜头防抖载体410的所述防抖磁石凹槽4104,如此设置所述镜头防抖磁石4131于所述镜头防抖载体410。并且,通过将所述镜头防抖磁石4131嵌入所述镜头防抖载体410的所述防抖磁石凹槽4104的方式,能够降低所述镜头防抖磁石4131的高度位置,从而有利于降低所述镜头驱动组件40的高度尺寸。
值得一提的是,通过将所述镜头防抖磁石4131嵌入所述镜头防抖载体410的所述防抖磁石凹槽4104的方式,所述镜头防抖磁石4131的顶面可以低于所述镜头防抖载体410的所述载体顶面4101,或者,所述镜头防抖磁石4131的顶面可以平齐于所述镜头防抖载体410的所述载体顶面4101。可以理解的是,通过将所述镜头防抖磁石4131嵌入所述镜头防抖载体410的所述防抖磁石凹槽4104的方式,所述镜头防抖磁石4131的顶面可以高于所述镜头防抖载体410的所述载体顶面4101。
可选地,在本发明的所述摄像模组的其他示例中,所述镜头防抖磁石4131可以分别被直接贴装于所述镜头防抖载体410的所述载体顶面4101。
所述镜头防抖驱动单元413包括四个所述镜头防抖磁石4131和四个所述镜头防抖线圈4132,每个所述镜头防抖磁石4131分别被设置于所述镜头防抖载体410的所述载体顶面4101,每个所述镜头防抖线圈4132分别被设置于所述镜头对焦内框420的所述镜头对焦内框顶部4201的所述内框底面42012,并且每个所述镜头防抖磁石4131的位置和每个所述镜头防抖线圈4132的位置分别相对。
为了便于描述和理解,定义所述镜头防抖驱动单元413的四个所述镜头防抖磁石4131分别为一第一防抖磁石4131a、一第二防抖磁石4131b、一第三防抖磁石4131c和一第四防抖磁石4131d,其中所述第一防抖磁石4131a、所述第二防抖磁石4131b、所述第三防抖磁石4131c和所述第四防抖磁石4131d分别被固定于所述镜头防抖载体410。相应地,定义所述镜头防抖驱动单元413的四个所述镜头防抖线圈4132分别为一第一防抖线圈4132a、一第二防抖线圈4132b、一第三防抖线圈4132c和一第四防抖线圈4132d,其中所述第一防抖线圈4132a、所述第二防抖线圈4132b、所述第三防抖线圈4132c和所述第四防抖线圈4132d分别被固定于所述镜头对焦内框420。

进一步地,所述芯片驱动组件10包括至少一芯片防抖导磁构件14,所述芯片防抖导磁构件14被罩设在所述芯片防抖磁石131的上方,如此:一方面,所述芯片防抖导磁构件14能够向下(即,所述芯片防抖线圈132所在的方向)加强磁场强度,以使所述芯片防抖驱动部13具有足够的驱动力来驱动所述芯片防抖可动部12做相对于所述芯片防抖固定部11的平移和/或旋转运动,另一方面,所述芯片防抖导磁构件14能够避免朝向所述镜头驱动组件40的方向漏磁而干扰所述镜头驱动组件40的磁场。
具体地,所述芯片防抖导磁构件14被设置于所述芯片防抖固定部11的所述上盖112,所述芯片防抖磁石131被设置于所述芯片防抖导磁构件14,即,所述芯片防抖磁石131通过被设置于所述芯片防抖导磁构件14的方式被设置于所述上盖112,如此能够保持所述芯片防抖导磁构件14于所述芯片防抖磁石131和所述上盖112之间。通过这样的结构设计,所述芯片防抖导磁构件14允许所述芯片防抖磁石131的磁力线朝向所述芯片防抖线圈132的方向集中,以增加所述芯片防抖驱动部13的磁场强度,同时减少外溢到所述镜头驱动组件40的磁场强度,从而避免对所述镜头驱动组件40产生磁干扰。

值得一提的是,所述芯片防抖导磁构件14的数量和所述芯片防抖磁石131的数量的对应关系在本发明的所述摄像模组中不受限制。例如,在附图14至图18示出的本发明的所述摄像模组的这个具体示例中,所述芯片防抖导磁构件14的数量和所述芯片防抖磁石131的数量一致,这样,在每个所述芯片防抖磁石131的上方可以分别罩设一个所述芯片防抖导磁构件14,如此所述芯片防抖导磁构件14和所述芯片防抖磁石131可以一一对应。可选地,在本发明的所述摄像模组的另一些示例中,所述芯片防抖导磁构件14的数量少于所述芯片防抖磁石131的数量,这样,一个所述芯片防抖导磁构件14能够罩设在至少两个所述芯片防抖磁石131的上方。

可选地,在本发明的所述摄像模组的另外一些示例中,所述芯片防抖可动部12可以没有设置所述芯片防抖电连接部123,此时所述芯片防抖驱动部13的这些所述芯片防抖线圈132分别被贴装于所述感光组件30的所述电路板31,以通过所述电路板31向这些所述芯片防抖线圈132供电。此时,所述感光组件30的所述电路板31可以被直接地贴装于所述芯片防抖可动载体121的所述载体背面1212。
继续参考附图14至图18,所述芯片防抖可动载体121具有多个载体缺口1214,这些所述载体缺口1214分别自所述载体正面1211延伸至所述载体背面1212,其中所述芯片防抖驱动部13的这些所述芯片防抖线圈132分别被保持在所述芯片防抖可动载体121的这些所述载体缺口1214,如此在所述芯片防抖电连接部123被贴装于所述芯片防抖可动载体121的所述载体背面1212的基础上,所述芯片防抖驱动部13的这些所述芯片防抖线圈132能够经所述芯片防抖可动载体121的所述多个载体缺口1214朝向所述芯片防抖磁石131的方向延伸。也就是说,所述芯片防抖可动载体121的这些所述载体缺口1214能够形成所述安置位1210,以分别用于安置所述芯片防抖线圈132。
值得一提的是,所述芯片防抖可动载体121的所述载体缺口1214的形状在本发明的所述摄像模组中不受限制。
优选地,在本发明的所述摄像模组的这个实施例中,所述芯片防抖驱动部13的这些所述芯片防抖线圈132分别被贴装于所述芯片防抖电连接部123,通过贴装所述芯片防抖电连接部123于所述芯片防抖可动载体121的所述载体背面1212的方式,能够分别保持这些所述芯片防抖线圈132于所述芯片防抖可动载体121的这些所述载体缺口1214。
可选地,在本发明的所述摄像模组的其他示例中,所述芯片防抖驱动部13的这些所述芯片防抖线圈132分别被固定于所述芯片防抖可动载体121,并且这些所述芯片防抖线圈132可以通过连接线被连接于所述芯片防抖电连接部123或被连接于所述电路板31。此时,所述芯片防抖可动载体121可以没有被设置所述载体缺口1214。
继续参考附图14至图18,所述芯片驱动组件10进一步包括至少一芯片防抖磁吸构件15,其中所述芯片防抖磁吸构件15被设置于所述芯片防抖可动部12,并且所述芯片防抖磁吸构件15的位置和所述芯片防抖驱动部13的所述芯片防抖磁石131的位置相对应,如此所述芯片防抖磁吸构件15和所述芯片防抖磁石131能够相互配合而在Z轴方向产生磁吸力,以悬持所述芯片防抖可动部12于所述芯片防抖固定部11的所述收容腔1101。
换言之,所述芯片防抖磁吸构件15和所述芯片防抖驱动部13的所述芯片防抖磁石131在Z轴方向产生的磁吸力能够保证所述芯片防抖可动部12的一组所述芯片防抖滚珠122始终贴紧所述芯片防抖固定部11的所述上盖112,由于所述芯片防抖可动部12在所述芯片防抖可动载体121的所述载体正面1211和所述上盖112的内壁之间设置有一组可滚动的所述芯片防抖滚珠122,因此,所述芯片防抖可动部12和所述芯片防抖固定部11之间是点摩擦接触,通过这样的方式,所述芯片防抖驱动部13能够顺畅地驱动所述芯片防抖可动部12做相对于所述芯片防抖固定部11的平移和/或旋转运动,以实现所述摄像模组的平移防抖和/或旋转防抖。
优选地,所述芯片防抖可动载体121具有一组保持槽1215,其形成于所述芯片防抖可动载体121的所述载体正面1211,其中所述芯片防抖滚珠122被可滚动地保持在所述芯片防抖可动载体121的所述保持槽1215,通过这样的方式,在所述芯片防抖驱动部13驱动所述芯片防抖可动部12做相对于所述芯片防抖固定部11的平移和/或旋转运动时,能够避免所述芯片防抖滚珠122自所述芯片防抖可动载体121和所述上盖112之间脱离,从而保证所述摄像模组的可靠性、稳定性。具体地,在所述芯片防抖驱动部13驱动所述芯片防抖可动部12的所述芯片防抖可动载体121做相对于所述芯片防抖固定部11的平移和/或旋转运动时,所述芯片防抖滚珠122的运动轨迹能够被限制在所述芯片防抖可动载体121的所述保持槽1215内,以使所述芯片防抖滚珠122始终支撑所述芯片防抖可动载体121和所述芯片防抖固定部11的所述上盖112。
也就是说,所述芯片防抖可动载体121的所述保持槽1215和所述芯片防抖滚珠122能够形成所述芯片驱动组件10的一芯片防抖支撑部17,即,所述芯片防抖支撑部17包括一组所述芯片防抖滚珠122和具有一组所述保持槽1215,其中一组所述保持槽1215分别形成于所述芯片防抖可动载体121的所述载体正面122,一组所述芯片防抖滚珠122分别被可滚动地保持于所述保持槽1215且位于所述芯片防抖可动载体121和所述上盖112之间,如此所述芯片防抖支撑部17能够支撑所述芯片防抖可动载体121和所述上盖112。所述芯片防抖滚珠122在 所述保持槽1215内可以沿着X轴和Y轴形成的平面移动,以为所述芯片防抖可动部12的移动提供移动空间。
进一步地,所述芯片防抖可动载体121具有至少一延伸柱1216,所述保持槽1215形成于所述延伸柱1216,并且所述保持槽1215的开口朝向所述芯片防抖固定部11的所述上盖112。所述保持槽1215的深度小于或等于所述芯片防抖滚珠122的直径,如此所述芯片防抖滚珠122的至少一部分可以凸出于所述保持槽1215,并且所述芯片防抖滚珠122的高度位置大于所述芯片防抖线圈132的高度位置,以使所述芯片防抖滚珠122能够分别与所述芯片防抖可动载体121的所述延伸柱1216和所述上盖112点摩擦接触。
可以理解的是,通过上述这样的结构设计,所述芯片防抖滚珠122的上部分面向所述上盖112的内壁形成的平面,所述芯片防抖滚珠122的下部分面向所述保持槽1215形成的凹槽,如此:一方面,所述芯片防抖滚珠122能够在所述芯片防抖可动载体121和所述上盖112之间进行滚动,另一方面,所述保持槽1215能够对所述芯片防抖滚珠122进行限位,以避免所述芯片防抖滚珠122脱落,从而保证所述摄像模组的可靠性。
可以理解的是,所述芯片防抖滚珠122使得所述芯片防抖磁石131和所述芯片防抖线圈132之间具有间隙,以避免所述芯片防抖磁石131和所述芯片防抖线圈132之间直接接触。优选地,形成于所述芯片防抖磁石131和所述芯片防抖线圈132之间的间隙的范围为0.05mm至0.5mm,以保证所述芯片防抖磁石131和所述芯片防抖线圈132之间具有良好的电磁感应。
进一步地,所述芯片驱动组件10包括至少三个所述芯片防抖支撑部17,以保证所述芯片防抖可动部12沿着X轴和Y轴形成的平滑平移和绕着Z轴旋转。也就是说,所述芯片防抖可动部12包括至少三个所述芯片防抖滚珠122,所述芯片防抖可动载体121具有至少三个所述保持槽1215。
优选地,在附图14至图18示出的所述摄像模组的这个具体示例中,所述芯片驱动组件10包括四个所述芯片防抖支撑部17,其分别被设置于所述第一位置组12101和所述第二位置组12102之间以及位于所述第二位置组12102和所述第三位置组12103之间。也就是说,所述芯片驱动组件10的四个所述芯片防抖支撑部17分别位于所述芯片防抖可动部12的四个转角处,以为所述芯片防抖可动部12提供更平稳的支撑,同时充分利用所述芯片驱动组件10的内部空间而使所述芯片驱动组件10的结构更紧凑。可选地,在本发明的所述摄像模组的另外一些示例中,所述芯片驱动组件10的所述芯片防抖支撑部17可以是滑块,其被可滑动地保持在所述芯片防抖可动载体121和所述上盖112之间,以用于平稳支撑所述芯片防抖可动部12。继续参考附图14至图18,所述芯片驱动组件10包括四个所述芯片防抖磁吸构件15,每个所述芯片防抖磁吸构件15分别被设置于所述芯片防抖可动部12的每个转角处,如此能够保证所述芯片防抖可动部12的平整度而使所述摄像模组的光轴能够垂直于所述感光组件30的所述感光元件32的感光面。
继续参考附图14至图18,在本发明的所述摄像模组的这个具体示例中,所述芯片防抖磁吸构件15被设置于所述芯片防抖电连接部123,以优化所述摄像模组的结构。可选地,在本发明的所述摄像模组的另外一些示例中,所述芯片防抖磁吸构件15可以被设置于所述芯片防 抖可动载体121,或者所述芯片防抖磁吸构件15可以被设置于所述感光组件30的所述电路板31,或者所述芯片防抖磁吸构件15被设置于所述芯片防抖可动载体121和所述芯片防抖电连接部123之间,或者所述芯片防抖磁吸构件15可以被设置于所述芯片防抖电连接部123和所述电路板31之间。
另外,在本发明的所述摄像模组的一些示例中,所述芯片防抖磁吸构件15和所述芯片防抖驱动部13的所述芯片防抖磁石131可以完全对准,即,所述芯片防抖磁吸构件15可以位于所述芯片防抖驱动部13的所述芯片防抖磁石131的正下方。在本发明的所述摄像模组的另一些示例中,所述芯片防抖磁吸构件15和所述芯片防抖驱动部13的所述芯片防抖磁石131可以没有完全对准,两者之间存在一些偏差。
可以理解的是,在所述芯片防抖驱动部13驱动所述芯片防抖可动部12做相对于所述芯片防抖固定部11的平移和/或旋转运动时,所述芯片防抖磁吸构件15会同步地产生相对于所述芯片防抖固定部11的平移和/或旋转运动,此时,所述芯片防抖磁吸构件15和所述芯片防抖磁石131之间也会产生一些偏差,但是所述芯片防抖磁吸构件15所在的平面和所述芯片防抖磁石131所在的平面始终是平行的,即,所述芯片防抖磁吸构件15所在的平面和所述芯片防抖磁石131所在的平面始终正交于Z轴,因此,所述芯片防抖磁吸构件15和所述芯片防抖磁石131能够相互配合而在Z轴方向产生磁吸力是指所述芯片防抖磁吸构件15所在的平面和所述芯片防抖磁石131所在的平面之间的磁吸力,包括但不限于竖直方向的磁吸力、偏移竖直方向的倾斜磁吸力。
继续参考附图14至图18,所述芯片驱动组件10进一步包括至少三芯片防抖位置感测元件16,其分别通过感测所述第一磁石组136、所述第二磁石组137和所述第三磁石组138的位置信息的方式感测所述芯片防抖可动部12于X轴方向平移、Y轴方向平移、Z轴方向旋转的位置信息。
优选地,三个所述芯片防抖位置感测元件16分别被定义为一第一感测元件161、一第二感测元件162以及一第三感测元件163。所述第一感测元件161被设置于所述第一线圈1321的所述线圈空间13202,以对应于所述第一磁石1311,其中所述第一感测元件161用于感测X轴方向平移时的磁场变化。所述第二感测元件162被设置于所述第四线圈1324的所述线圈空间13202,以对应于所述第四磁石1314,其中所述第二感测元件162用以感测Y轴方向平移时的磁场变化。所述第三感测元件163被设置于所述第五线圈1325的所述线圈空间13202,以对应于所述第五磁石1315,其中所述第二感测元件162和所述第三感测元件163用于感测Z轴方向旋转时的磁场变化。
优选地,所述芯片防抖位置感测元件16被贴装于所述芯片防抖电连接部123。
在本发明的所述摄像模组中,所述芯片防抖驱动部13的所述第一线圈组133、所述第二线圈组134和所述第三线圈组135是独立控制的线圈组,因此仅需设置三个所述芯片防抖位置感测元件16即可,如此不仅能够减少所述芯片驱动组件10的元件数量,利用较少的数量接口实现平移防抖和/或旋转防抖的感测而有利于减小所述芯片驱动组件10的尺寸,而且能够充分地利用所述芯片驱动组件10的内部空间而使得所述芯片驱动组件10的结构紧凑。
值得一提的是,在本发明的所述摄像模组的一些实施例中,所述芯片防抖位置感测元件16可以是霍尔元件。在发明的所述摄像模组的另一些实施例中,所述芯片防抖位置感测元件16可以是驱动I C,其适于在获取所述芯片防抖磁石131的位置变化的同时控制所述芯片防抖线圈132的电流。具体地,当所述摄像模组开启防抖功能后,所述芯片防抖位置感测元件16能够感测当前的所述第一磁石组136、所述第二磁石组137和所述第三磁石组138的当前位置,并通过控制所述第一线圈组133、所述第二线圈组134和所述第三线圈组135的电流的方式驱动所述芯片防抖可动部12移动至感测的中心位置,当所述摄像模组关闭防抖功能后,通过所述感光组件30的所述电路板31的反发力(即,所述芯片防抖可动部12在被平移和/或旋转时,所述电路板31因产生弹性形变而积蓄的弹性力)使得所述芯片防抖可动部12返回至初始位置。
附图19示出了本发明的所述摄像模组的一个变形示例,与附图1至图18示出的所述摄像模组不同的是,在附图19示出的所述摄像模组的这个变形示例中,所述第一线圈组133包括四个所述防抖线圈132,其中组成所述第一线圈组133的两个所述防抖线圈132相互对称地设置在所述感光元件32的所述第二芯片侧边322和所述第四芯片侧边324中的一端,另外两个所述防抖线圈132相互对称地设置在所述感光元件32的所述第二芯片侧边322和所述第四芯片侧边324中的另外一端。所述芯片防抖可动载体121的四个所述保持槽1215分别形成于所述感光元件32的所述第一芯片侧边321、所述第二芯片侧边322、所述第三芯片侧边323和所述第四芯片侧边324的中部,如此使得四个所述滚珠122分别于所述感光元件32的所述第一芯片侧边321、所述第二芯片侧边322、所述第三芯片侧边323和所述第四芯片侧边324的中部被可滚动地保持在所述芯片防抖可动载体121的所述载体正面1211和所述上盖112的内壁之间。
本领域的技术人员应理解,上述描述及附图中所示的本发明的实施例只作为举例而并不限制本发明。本发明的目的已经完整并有效地实现。本发明的功能及结构原理已在实施例中展示和说明,在没有背离所述原理下,本发明的实施方式可以有任何变形或修改。
