本发明要求在2020年04月17日提交中国专利局、申请号为202010306951.7发明名称为“摄像模组及电子设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本发明涉及通信技术领域，尤其涉及一种摄像模组及电子设备。
背景技术
随着拍照和摄像功能在手机终端上的应用越来越广泛，使用者对手机相机的成像质量要求也越来越高。其中，在手机相机进行拍照或摄像的过程中，为了避免因手持或走动所产生的抖动而导致镜头模组的图像模糊、造成手机相机成像质量下降的问题，手机相机的镜头模组配备了相应的防抖稳定***来补正抖动时的镜头模组的图像偏移、以保证手机相机的成像质量。
目前，手机的防抖稳定***主要通过平移或倾斜镜头的方式对镜头模组的图像偏移进行补正。但是，由于平移或倾斜镜头的方式使得镜头相对于感光芯片都发生了相对移动或倾斜，所以在光学上要求镜头的直径比感光芯片的尺寸大、来覆盖相对移动或倾斜时的感光芯片的成像区域，进而需将镜头的直径设计的较大。
发明内容
本发明公开一种摄像模组及电子设备，以解决目前手机相机的防抖稳定***所导致的镜头模组的镜头直径设计较大的问题。
为了解决上述问题，本发明采用下述技术方案：
第一方面，本发明提供了一种摄像模组，包括镜头模组和防抖模组；所述防抖模组包括外框架和第一驱动组件，所述镜头模组转动设置于所述外框架之内；所述第一驱动组件包括第一驱动线圈和第一磁性元件；所述第一驱动线圈和所述第一磁性元件中的一者设置于所述外框架，另一者设置于所述镜头模组，且所述第一驱动线圈位于所述第一磁性元件的磁场中；在所述第一驱动线圈通电的情况下，所述镜头模组可相对于所述外框架转动。
第二方面，本发明提供了一种电子设备，所述电子设备包括上述的摄像模组。
本发明公开的摄像模组及电子设备，通过第一磁性元件的磁场使得第一驱动线圈在通电的情况下可以受到第一磁性元件的安培力，并可以通过调节通入电流的大小、方向，来实现对第二驱动线圈的安培力的大小、方向进行调节。由此，利用第一驱动线圈受到的安培力可以对镜头模组进行转动调节，如此即实现了对抖动时的图像偏移量进行补正，进而提高了镜头模组的成像质量。
本发明实施例公开的摄像模组可以在转动过程中保持镜头与感光芯片之间的相对位置不变，镜头采用较小的直径设计尺寸即可满足成像要求，其在实现拍摄防抖的基本功能之外，无疑能够优化电子设备内部的结构布局。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例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。
以下结合附图，详细说明本发明各个实施例公开的技术方案。
请参考图1至图10所示，本发明实施例公开了一种摄像模组，所公开的摄像模组包括镜头模组和防抖模组。
防抖模组作为镜头模组的防抖功能组件，可以对镜头模组的图形偏移进行补正，避免因抖动而影响图像的成像质量。
本发明实施例公开的防抖模组包括外框架100和第一驱动组件，镜头模组转动设置于外框架100之内，也即是说，镜头模组可在外框架100内相对于外框架100发生相对转动。
其中，第一驱动组件包括第一驱动线圈102和第一磁性元件420；第一驱动线圈102和第一磁性元件420中的一者设置于外框架100，另一者设置于镜头模组，且第一驱动线圈102位于第一磁性元件420的磁场中，从而在电流通过第一驱动线圈102时，第一磁性元件420的磁场可以对第一驱动线圈102产生安培力。第一磁性元件420可以为永磁铁或电磁铁。
在第一驱动线圈102通电的情况下，镜头模组可相对于外框架100转动。具体而言，通过第一磁性元件420的磁场使得第一驱动线圈102在通入电流的情况下可以受到第一磁性元件420的安培力，并可以通过调节通入电流的大小、方向，来实现对第一驱动线圈102的安培力的大小、方向进行调节。
由此，利用第一驱动线圈102受到的安培力可以对镜头模组进行转动调节，如此即实现了对抖动时的图像偏移量进行补正，进而提高了镜头模组的成像质量。
相较于现有技术中所采用的通过平移或倾斜镜头300对镜头模组的图形偏移进行补正的方式，本发明实施例公开的摄像模组既可以补正抖动时的图像偏移量、提高镜头模组的成像质量，又可以在转动过程中保持镜头300与感光芯片510之间的相对位置不变、减小镜头300的直径设计尺寸，优化了电子设备内部的结构布局。
为了使得镜头模组能够实现任意方向上的角度补偿，在可选的方案中，防抖模组还可以包括内框架200和第二驱动组件，内框架200转动设置于外框架100之内。更为具体地，内框架200可绕第一转轴转动而设置于外框架100，且镜头模组可绕第二转轴转动而设置于内框架200，第一转轴和第二转轴的转动轴线相交设置，从而使得镜头模组和内框架200之间互不干扰，镜头模组可以单独绕第二转轴转动、也可同时与内框架200一起绕第一转轴转动，进而使得镜头模组可以在任意方向上的转动调节，实现镜头模组更大范围的防抖。
其中，第二驱动组件包括第二驱动线圈101和第二磁性元件410；第二驱动线圈101和第二磁性元件410中的一者设置于外框架100，另一者设置于内框架200或镜头模组，且第二驱动线圈101位于第二磁性元件410的磁场中，从而在电流通过第二驱动线圈101时、第二磁性元件410的磁场可以对第二驱动线圈101产生安培力。第二磁性元件410可以为永磁铁或电磁铁。
在第二驱动线圈101通电的情况下，内框架200和镜头模组可相对于外框架100转动。具体而言，通过第二磁性元件410的磁场使得第二驱动线圈101在通入电流的情况下可以受到第二磁性元件410的安培力，并可以通过调节通入电流的大小、方向，来实现对第二驱动线圈101的安培力的大小、方向进行调节。由此，结合前述，利用第二驱动线圈101和第一驱动线圈102受到的安培力可以分别对镜头模组和内框架200进行转动调节，且镜头模组和内框架200的转动调节互不干扰、实现了整个镜头模组在任意方向上的转动，即镜头模组在任意方向上发生抖动时都能够对其图像偏移量进行补正，进而进一步提高了镜头模组的成像质量。
在本实施例中，未限制第二驱动线圈101、第一驱动线圈102、第二磁性元件410和第一磁性元件420的种类和设置位置，当然它们需要保持各自的对应设置关系。
在具体的实施方式中，第二磁性元件410和第一磁性元件420设置于镜头模组，且第二磁性元件410和第一磁性元件420位于第一转轴的同一侧、并位于所述第二转轴的两侧；或者，第二磁性元件410和第一磁性元件420位于第二转轴的同一侧、并位于第一转轴的两侧。又或者，第二驱动线圈101和第一驱动线圈102可以设置于镜头模组上，相应地，第二磁性元件410和第一磁性元件420设置于外框架100上；同时，第二磁性元件410和第一磁性元件420也可以位于第一转轴的同一侧、并分别位于第二转轴的两侧。具体地，镜头模组包括镜头300和第三驱动组件400，镜头300活动设置于第三驱动组件400之中、并可通过第三驱动组件400调节所述镜头300的焦距。通常情况下，第三驱动组件400 为音圈马达，音圈马达在工作时可对镜头300产生驱动作用而驱使镜头300移动，进而调节镜头300的焦距。
其中，如图2和图4所示，第三驱动组件400可以包括第三驱动线圈411、第四驱动线圈，第二磁性元件410和第一磁性元件420设置于镜头300的两侧、并分别与镜头300留有活动间距，第三驱动线圈411和第四驱动线圈设置于镜头300的外壁上，且第三驱动线圈411位于朝向第二磁性元件410的一侧、第四驱动线圈位于朝向第一磁性元件420的一侧，从而在第三驱动线圈411和第四驱动线圈通电时，利用第二磁性元件410与第三驱动线圈411、第一磁性元件420与第四驱动线圈所产生的安培力控制镜头300转动，实现镜头300焦距的调节。
由上可知，可选地，第二驱动线圈101和第三驱动线圈411可以共用第二磁性元件410，而第一驱动线圈102和第四驱动线圈可以共用第一磁性元件420，进而使得摄像模组内部的空间得到充分利用，避免了设置额外的磁性元件。当然，本实施例对第三驱动组件400的具体结构不做限制，第三驱动组件400也可以包括独立的磁性元件，则第一磁性元件420和第二磁性元件410可以设置在第三驱动组件400之外。
如前所述，第二磁性元件410和第一磁性元件420可以位于第二转轴的同一侧、并分别位于第一转轴的两侧，第二驱动线圈101和第一驱动线圈102可以设置于外框架100，且第二驱动线圈101与第二磁性元件410位于相对的位置、第一驱动线圈102与第一磁性元件420位于相对的位置；其中，可参见图3和图4中所示，镜头模组的转动调节过程可如下述示例进行说明。
当第二驱动线圈101和第一驱动线圈102分别通入大小相同的正向电流，根据左手定则可知第二驱动线圈101和第一驱动线圈102受到向上的安培力，因外框架100固定所以使得第二磁性元件410和第一磁性元件420受到第二驱动线圈101和第一驱动线圈102的反作用力、向下推动镜头模组随内框架200一起绕第二转轴进行正向转动调节。
当第二驱动线圈101和第一驱动线圈102分别通入大小相同的反向电流，根据左手定则可知第二驱动线圈101和第一驱动线圈102受到向下的安培力，因外框架100固定所以使得第二磁性元件410和第一磁性元件420受到第二驱动线圈101和第一驱动线圈102的反作用力、向上推动镜头模组随内框架200一起绕第二转轴进行反向转动调节。
当第二驱动线圈101通入正向电流、第一驱动线圈102通入反向电流，且正向电流与反向电流的大小可以相同；根据左手定则可知第二驱动线圈101受到向上的安培力、第一驱动线圈102受到向下的安培力，因外框架100固定所以使得第二磁性元件410受到第二驱动线圈101的反作用力向下推动镜头模组、第一磁性元件420受到第一驱动线圈102的反作用力向上推动镜头模组，从而使得镜头模组绕第一转轴进行正向转动调节。
当第二驱动线圈101通入反向电流、第一驱动线圈102通入正向电流，且反向电流与正向电流的大小可以相同；根据左手定则可知第二驱动线圈101受到向下的安培力、第一驱动线圈102受到向上的安培力，因外框架100固定所以使得第二磁性元件410受到第二驱动线圈101的反作用力向上推动镜头模组、第一磁性元件420受到第一驱动线圈102的反作用力向下推动镜头模组，从容使得镜头模组绕第一转轴进行反向转动调节。
当第二驱动线圈101和第一驱动线圈102断电时，第二驱动线圈101和第一驱动线圈102无电流通过，所以第二磁性元件410和第一磁性元件420不产生安培力，从而使得镜 头模组和内框均处于静止状态。
在可选的方案中，参考图2、图3和图7所示，第二磁性元件410包括磁极相反设置的第三磁性部4101和第四磁性部4102，第三磁性部4101的N极和第四磁性部4102的S极分别朝向第二驱动线圈101在通电时电子移动方向相反的线圈部，第三磁性部4101的S极和第四磁性部4102的N极分别朝向第三驱动线圈411在通电时电子移动方向相反的线圈部；第一磁性元件420包括磁极相反设置的第一磁性部和第二磁性部，第一磁性部的N极和第二磁性部的S极分别朝向第一驱动线圈102在通电时电子移动方向相反的线圈部，第一磁性部的S极和第二磁性部的N极分别朝向第四驱动线圈421在通电时电子移动方向相反的线圈部；从而使得第二磁性元件410的磁场和第一磁性元件420可以更好地作用于相应导电线圈的电子移动方向相反的部分，使得整个线圈均可以受到安培力作用；其中，第三磁性部4101和第四磁性部4102可以为两块并排、且磁极相反设置的磁铁。
同时，第三驱动组件400还可以包括壳体，壳体设置有收容腔以及与收容腔连通的开口；镜头300的一端位于收容腔之中、另一端可伸缩地设置于开口，也即是说，镜头300的另一端可通过开口进行变焦移动；镜头300背离开口的一侧设置有感光芯片510和电路板500，感光芯片510设置于电路板500上、并朝向镜头300；第二磁性元件410和第一磁性元件420设置于收容腔的内侧壁，从而通过壳体不仅可以为导电线圈、第二磁性元件410、第一磁性元件420、感光芯片510以及电路板500等组件的设置提供承载基础，而且还可以兼顾保护和外观性能。
并且，为了避免壳体对第二磁性元件410和第一磁性元件420的磁场的阻碍，壳体的侧面与第二磁性元件410和第一磁性元件420对应位置分别开设有窗口450，从而通过相应的窗口450使得第二磁性元件410和第一磁性元件420的磁场穿过壳体、并分别作用于对应的第二驱动线圈101和第一驱动线圈102。
为了提高第三驱动组件400移动镜头300变焦的稳定性，第三驱动组件400还可以包括第三磁性元件430和第五驱动线圈431；如图2和图4所示，第五驱动线圈431设置于镜头300、并位于与第三驱动线圈411相对的一侧；第三磁性元件430设置于收容腔的内侧壁、并与第二磁性元件410相对；从而在第三驱动组件400对镜头300进行变焦移动的过程中，可以使镜头300组件相对的两侧均受到作用力、进而提高移动的稳定性。
本发明实施例公开的摄像模组还可以包括角度检测模组，角度检测模组用于检测内框架200和镜头模组中至少一者的转动角度。应理解的是，通过角度检测模组获取内框架200和镜头模组的转动角度，即可以确定镜头模组进行防抖补偿是否转动到位。
具体地，角度检测模组可以包括用于分别检测内框架200和镜头模组的第一传感器1011和第二传感器1021；第一传感器1011和第二传感器1021中，一者设置于第一驱动线圈102上、另一者设置于第二驱动线圈101上。可选地，第一传感器1011和第二传感器1021可以为霍尔传感器。
具体而言，基于第一传感器1011和第二传感器1021，即可检测内框架200和镜头模组的转动角度。需要说明的是，通过霍尔元器件检测转动角度为本领域的常规技术，故不再赘述。当然，第一传感器1011和第二传感器1021也可以为角度传感器、陀螺仪等其他类型的角度检测元件。
角度检测模组还可以包括处理器；第一传感器1011和第二传感器1021分别与处理器 的信号输入端连接；处理器的控制输出端分别与第二驱动线圈101和第一驱动线圈102连接，并可根据第一传感器1011和第二传感器1021控制第二驱动线圈101和第一驱动线圈102的电流；从而使得第一传感器1011、第二传感器1021、处理器、第二驱动线圈101和第一驱动线圈102构成形成一个闭环的控制***，实现对镜头模组和内框架200转动调节的精准控制。
同时，镜头模组中的电路板500设置有第一线路板501，从而通过第一线路板501方便于电路板500与电子设备的主板连接，并且如图10所示，为了避免镜头模组转动对线路板的影响，第一线路板501可以为柔性线路板、并折叠弯曲呈S形；第一线路板501的连接端可以设置连接器。
第二驱动线圈101和第一驱动线圈102可以设置于第二线路板103上，从而通过第二线路板103方便于与处理器或电子设备的主板连接；第二线路板103可以为柔性线路板，且第二线路板103的连接端可以设置连接器。
本发明实施例公开的摄像模组中，为了方便于内框架200与外框架100以及内框架200与镜头模组之间的转动装配，如图6所示：内框架200包括两个第一安装座210，相应地、外框架100的内侧壁与第一安装座210对应的位置分别设置有第一转动座110，且一个第一安装座210对应于一个第一转动座110；相对应的第一安装座210和第一转动座110中，一者设置有第一凸部、另一者设置有与第一凸部适配的第一凹陷部，从而可以将第一凸部嵌入第一凹陷部之内，使得第一凸部与第一凹陷部转动配合，由此，两个第一凸部就形成了第一转轴，进而实现内框架200与外框架100之间的转动装配。
内框架200包括两个第二安装座220，相应地、镜头模组的外侧壁与第二安装座220对应的位置分别设置有第二转动座120，且一个第二安装座220对应于一个第二转动座120；相对应的第二安装座220和第二转动座120中，一者设置有第二凸部、另一者设置有与第二凸部适配的第二凹陷部，从而可以将第二凸部嵌入第二凹陷部之内，使得第二凸部与第二凹陷部转动配合，由此，两个第二凸部就形成了第二转轴，进而实现内框架200与镜头模组之间的转动装配。
其中，如图8和图9所示，第一凸部和第二凸部的形状为圆柱状，第一凹陷部和第二凹陷部为盲孔或通孔；当然，第一凸部和第二凸部也可以为圆弧形凸起，第一凹陷部和第二凹陷部可以为相应的圆弧形凹槽；本发明实施例不限制第一凸部、第二凸部、第一凹陷部和第二凹陷部的形状。
同时，如图5、图7和图9所示，镜头模组上被第二转轴的转动轴线所通过的两侧外壁分别设置有安装部440，安装部440的一端与镜头模组连接，安装部440的另一端沿镜头模组的外侧壁延伸，且安装部440与镜头模组之间具有间隙；一个第二转动座120对应于的一个安装部440，且第二转动座120位于间隙之内、并设置于安装部440朝向镜头模组的内侧面上；从而通过安装部440方便于第二转动座120的安装设置。
安装部440可以为板状结构件、也可以为凸台状结构件等；镜头模组的形状可以为八边形、也可以为方形或圆形等；本发明实施例不限制安装部440以及镜头模组的形状。
本发明实施例还公开了一种电子设备，所公开的电子设备设置有本发明实施例公开的上述摄像模组；同时，防抖模组可以与电子设备的陀螺仪和驱动芯片连接，从而控制防抖模组中的第二驱动线圈101和第一驱动线圈102的电流；其中，电子设备可以为智能手机、 平板电脑、电子书阅读器等电子设备。
本发明上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上仅所述为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
