本申请实施例提出一种摄像头模组及电子设备。下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域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，都属于本申请保护的范围。
请参阅图1和图2，图1为本申请实施例提供的电子设备的结构示意图，图2为图1所示电子设备中 摄像头模组的结构示意图。本申请实施例提供的电子设备1000具体可以是手机、平板电脑、笔记本电脑和穿戴设备等便携设备，下面以手机为例进行说明。如图1所示，电子设备1000可以包括壳体200、摄像头模组400以及显示屏600。显示屏600设置在壳体200上，其可以用于显示画面，摄像头模组400可以设置于壳体200，并能够接受到外部环境射入的光线以实现画面拍摄。
如图2所示，摄像头模组400可以包括防抖机构420、镜头440、感光元件460和防抖模组480。其中，镜头440设置在防抖机构420上，通过防抖机构420驱动镜头440移动而实现摄像头模组400的镜头的防抖功能。感光元件460设置在防抖机构420的一侧，而且在平行于防抖机构420的轴向上与镜头440相对设置。防抖模组480与防抖机构420设置在感光元件460同一侧，并且防抖模组480与感光元件460连接，防抖模组480用于驱动感光元件460在垂直于镜头440的光轴方向的平面移动，从而实现摄像头模组400的感光元件460的防抖功能。在本实施例中，摄像头模组400可以用于实现电子设备1000的拍照、录像、人脸识别解锁、扫码支付等功能。此外，需要说明的是，摄像头模组400可以是如图示中所示的后置式摄像头的，也可以是前置式摄像头，本实施例对此不作限定。
具体地，镜头440的材质可以是玻璃或塑胶等。镜头440主要用于改变光线的传播路径，并对光线进行聚焦。镜头440可以包括多组镜片，多组镜片会相互矫正过滤光线；以在光线通过镜头440时，多组镜片层层过滤杂光(例如红外光)，以便于增加摄像头模组400的成像效果。感光元件460具体可以是CCD(Charge Coupled Device，电荷耦合元件)这类影像传感器，也可以是CMOS(Complementary Metal Oxide Semiconductor，互补金属氧化物半导体)这类影像传感器。感光元件460可以在摄像头模组400的光轴方向(也即是镜头440的光轴方向，如图2中虚线所示)上与镜头440相对设置，主要用于接收来自镜头440采集的光线，并将光信号转化为电信号，以便于实现摄像头模组400的成像需求。防抖机构420则主要用于改善摄像头模组400因用户在使用过程中发生抖动而产生的成像效果，以使得感光元件460的成像效果能够满足用户的使用需求。
基于光学防抖技术，电子设备1000(或摄像头模组400)的陀螺仪或加速度计等传感器可以检测到镜头440的抖动以生成抖动信号，并将该抖动信号传递至电子设备1000和/或摄像头模组400的处理芯片，电子设备1000和/或摄像头模组400的处理芯片可以计算出防抖机构420需要补偿的位移量，以使得防抖机构420可以根据镜头440的抖动方向及其位移量对镜头440进行补偿，从而改善或摄像头模组400因用户在使用过程中发生抖动而产生的成像效果。
下面就防抖机构420的具体结构及其与摄像头模组400中其它结构件之间的配合关系进行详细的说明。
请结合图3至图4，图3为图2所示摄像头模组中防抖机构的结构示意图，图4为图2所示防抖机构的 爆炸结构示意图。防抖机构420可以包括承载组件421和第一线圈4232。其中，承载组件421用于承载镜头440，第一线圈4232设置在承载组件421远离感光元件一侧，并且第一线圈4232能够驱动承载组件421沿垂直于镜头440的光轴方向移动。防抖模组480能够驱动感光元件460进行移动以实现感光元件460的防抖，第一线圈4232能够驱动镜头440进行移动以实现镜头440的防抖，通过防抖模组480和第一线圈4232实现感光元件460和镜头440的双重防抖，能够得到更大的防抖角度。另外，第一线圈4232设置在承载组件421远离感光元件460一侧，可以避免与防抖模组480干涉，同时防止摄像头模组400的高度过高。
请结合图5，图5为图4所示摄像头模组中电路板的结构示意图。摄像头模组400还可以包括电路板427，电路板427设置在第一线圈4232远离所述承载组件421一侧，电路板427与第一线圈4232电连接。电路板427可以控制第一线圈4232的通断。
电路板427远离承载组件421一侧可以设有第一感应元件4272，第一感应元件4272用于获取摄像头模组400的抖动信息。摄像头模组400根据该抖动信息可以控制第一线圈4232的通断从而进行镜头440的防抖。
摄像头模组400还包括上盖426，上盖426盖设于电路板427，上盖426设有露出感应元件4272的开口4264。上盖426露出感应元4272可以降低上盖426和电路板427之间的距离，降低摄像头模组400的整体高度。
电路板427包括主体部4274和弯折部4276，主体部4274设置在上盖426和承载组件421之间，弯折部4276设置在主体部和感光元件之间，也可以理解为，弯折部4276从主体部4274朝向感光元件一侧弯折延伸，弯折部4276一端与主体部4274弯折连接，弯折部4276另一端与所述承载组件421连接。
其中，弯折部4276包括依次连接的连接部42762、第一弯折边42764和第二弯折边42766，第一弯折边42764沿第一方向延伸，第二弯折边42766沿第二方向延伸，第一方向和第二方向垂直，第一弯折边42764通过连接部42762与主体部4274弯折连接，第二弯折边42766与承载组件421连接。
弯折部4276包括至少两个方向的弯折边，为了更好的设置两个弯折边，第一弯折边42764和第二弯折边42766可以垂直设置。可以理解的是，第一弯折边42764和第二弯折边42766可以围绕承载组件421的边缘设置。
第二弯折边42766远离第一弯折边42764的一端设有第二感应元件(图中未示出)，第二感应元件用于获取摄像头模组400的对焦信息。摄像头模420组根据第二感应元件获取的对焦信息进行对焦操作。
电路板427还包括自主体部4274边缘朝感光元件突出的延伸部4278，延伸部4278位于摄像头模组400外侧，延伸部4278上设有连接引脚。延伸部4278位于摄像头模组400的整体外侧，延伸部4278上的连接引脚可以用来与外部设备连接，如与电子设备的主处理器电性连接。
其中，第二弯折边42766设置第二感应元件的一端可以和延伸部4278相对设置，延伸部4278位于承载组件421的外侧，第二弯折边42766设置第二感应元件的一端可以向内凹陷设置，如承载组件对应延伸部设有一凹陷结构，第二弯折部设置第二感应元件的一端可以向该凹陷结构弯折设置。
需要说明的是，电路板可以为柔性电路板，当第一线圈驱动承载组件进行防抖作动时，其他部件如对焦组件为固定部，具有弯折部的电路板可以降低相对于固定部的防抖作动的反拉力。
防抖机构420还可以包括第一驱动组件422。第一驱动组件422设置在承载组件421上，第一驱动组件422能够驱动承载组件421沿平行于镜头440的光轴方向移动，当承载组件421沿平行于镜头440的光轴方向移动时可以带动镜头440一起沿平行于镜头440的光轴方向移动，以补偿镜头440在平行于镜头440的光轴方向的抖动量。第一线圈4232能够驱动承载组件421沿垂直于镜头440的光轴方向移动，当承载组件421沿垂直于镜头440的光轴方向移动时可以带动镜头440一起沿垂直于镜头440的光轴方向移动，以补偿镜头440在垂直于镜头440的光轴方向的抖动量。同时，防抖模组480能够驱动感光元件460沿垂直于镜头440的光轴方向移动，以补偿感光元件460在垂直于镜头440的光轴方向的抖动量。
相比于相关技术中仅采用一个弹片式驱动马达或一个滚珠式驱动马达同时实现水平方向和竖直方向的位移，本申请实施例采用两个不同驱动结构分别对承载组件进行两个不同方向的驱动，可以防止由于同一个驱动结构在同时实现两种不同方向的位移时导致驱动部分部件损坏的情况，从而提高防抖机构420的防抖可靠性，提升防抖机构420的整体性能。
此外，经发明人长期研究发现，一些手机的弹片式驱动马达通常运用弹片结构以及吊环线结构实现驱动马达的水平方向以及竖直方向的位移以带动镜头的水平方向以及竖直方向的位移，然而在实现水平方向位移过程中容易出现弹片结构和/或吊环线断裂的问题；一些手机的滚珠式驱动马达通常采用多个滚珠实现驱动马达的水平方向以及竖直方向的位移以带动镜头的水平方向以及竖直方向的位移，然而在实现竖直方向的位移过程中，多个滚珠会相互撞击从而使得多个滚珠容易出现凹坑而导致滚动不顺畅的问题。
基于此，本申请实施例的第一驱动组件422包括弹性结构4221，弹性结构4221被配置为弹性作用力能够使得承载组件421沿平行于镜头440的光轴方向移动。摄像头模组还包括滚动结构4231，滚动结构4231和第一线圈4232组成第二驱动组件423，滚动结构4231被配置为能够使得承载组件421基于滚动结构4231的滚动操作而实现沿垂直于镜头440的光轴方向移动。
可以理解的是，本申请实施例的第一驱动组件422通过弹性结构4221实现承载组件421的上下移动，第二驱动组件423通过滚动结构4231实现承载组件421的左右移动，相对于相关技术，可以避免弹性结构4221同时受到上下移动和左右移动等两个相互垂直的方向的拉扯而容易断裂的问题，以及可以避免滚动 结构4231在实现上下移动过程中容易出现凹坑而导致滚动不顺畅的问题。
需要说明的是，本申请实施例中所有方向性指示(诸如上、下、左、右、前、后)仅用于解释在某一特定姿态下各部件之间的相对位置关系、移动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
结合图5和图6所示，图6为图4所示防抖机构的第一种部分结构示意图，承载组件421可以包括第一载体4211、第二载体4212和导向件4213，第二载体4212和导向件4213均设置在第一载体4211上。第一载体4211可以为规则形状，比如第一载体4211可以为矩形的框架结构，其可以具有依次连接的第一侧边42111、第二侧边42112、第三侧边42113和第四侧边42114，第一侧边42111和第三侧边42113相对设置，第二侧边42112与第四侧边42114相对设置。第一载体4211还设置有收纳空间42115，该收纳空间42115由第一侧边42111、第二侧边42112、第三侧边42113和第四侧边42114围设形成，其可以收纳防抖机构420的部分器件。当然，第一载体4211也可以为圆角矩形或不规则形状。
第二载体4212可以容置在收纳空间42115内，而且第二载体4212还可以在收纳空间42115内移动。其中，镜头440可以设置在第二载体4212上，当第二载体4212移动时可以带动镜头440移动。示例性的，第二载体4212也可以为矩形框架结构，其可以包括相互连接的第一支撑部42121、第二支撑部42122、第三支撑部42123和第四支撑部42124，第一支撑部42121和第三支撑部42123相对设置，第二支撑部42122与第四支撑部42124相对设置。第二载体4212可以设置有通孔42125，镜头440可以穿设于通孔42125，且与通孔42125的孔壁固定。

导向件4213在平行于镜头440的光轴方向上层叠设置于第一载体4211的一部分上，以使得第一载体4211的一部分裸露于导向件4213外部。比如，导向件4213可以包括相互连接的第一侧部42131和第二侧部42132，其大致呈“L”型结构。第一侧部42131可以层叠在第一侧边42111上，第二侧部42132可以层叠在第二侧边42112上，以使得第三侧边42113和第四侧边42114裸露在导向件4213外部，或者说第三侧边42113和第四侧边42114未与导向件4213的一部分层叠设置。相比于相关技术中，矩形结构的导向件4213，本申请实施例的导向件4213可以减小导向件4213的体积，从而减少导向件4213对防抖机构420的空间占用，有利于防抖机构420的小型化。
如图4所示，防抖机构420还可以包括磁性组件424，磁性组件424可以为永磁体或者电磁铁，其可以产生磁场。其中磁性组件424可以设置在承载组件421上，而且磁性组件424可以包括多个磁性件，每 一磁性件均可以包括磁性相反的两个磁体。
第一驱动组件422位于磁性组件424所产生的磁场内，而且第一驱动组件422在磁性组件424的作用下能够带动承载组件421沿平行于镜头440的光轴方向移动。比如，第一驱动组件422还可以包括第一导电件4222，第一导电件4222在垂直于镜头440的光轴方向上与磁性组件424相对设置，基于弗莱明左手定则，第一导电件4222通电之后可以产生一个磁场，第一导电件4222所产生的磁场可以与磁性组件424的磁场相互作用而产生垂直于镜头440的光轴方向第一作用力(或者说磁性作用力)，弹性结构4221能够产生垂直于镜头440的弹性作用力，第一作用力和弹性作用力同时作用于承载组件421，承载组件421在第一作用力和弹性作用力的驱动下，可以实现上下移动，从而带动镜头440上下移动，以实现镜头440的自动对焦和/或补偿镜头440在竖直方向上的抖动。
示例性的，请参阅图4和图6，第一驱动组件422可以包括两个第一导电件4222，两个第一导电件4222在垂直于镜头440的光轴方向上相对设置于第二载体4212的两侧，比如一个第一导电件4222可以设置在第一支撑部42121上，另一个第一导电件4222可以设置在第三支撑部42123上。两个第一导电件4222的结构可以相同，比如两个第一导电件4222可以均为图5所示的环状结构，第一支撑部42121和第三支撑部42123均可以设置有限位结构，一个第一导电件4222可以卡设在第一支撑部42121的限位结构上，另一个第一导电件4222可以卡设在第三支撑部42123的限位结构上。当然，两个第一导电件4222也可以为单杆结构或双杆结构。在一些实施例中，两个第一导电件4222的结构也可以不同，比如一个第一导电件4222可以为环状结构，另一个第一导电件4222可以为单杆结构或双杆结构等。
磁性组件424可以包括第一磁性件4241、第二磁性件4242和第三磁性件4243，第一磁性件4241、第二磁性件4242和第三磁性件4243可以均设置在第一载体4211上。
比如，结合图7至图9所示，图7为图4所示防抖机构中第一载体的结构示意图，图8为图3所示防抖机构的第二种部分结构示意图，图9为图3所示防抖机构的第三种部分结构示意图。第一载体4211设置有第一容置槽42116a、第二容置槽42116b和第三容置槽42116c，第一容置槽42116a设置在第一侧边42111上，第二容置槽42116b设置在第三侧边42113上，第三容置槽42116c设置在第四侧边42114上。第一磁性件4241设置在第一容置槽42116a中，而且在垂直于镜头440的光轴方向上与一个第一导电件4222相对设置以使得一个第一导电件4222位于第一磁性件4241所产生的磁场内，一个第一导电件4222在通电时可以产生磁场，并与第一磁性件4241所产生的磁场相互作用，并对第二载体4212产生推力。
其中，第一磁性件4241可以包括第一磁体42411和第二磁体42412，第一磁体42411的磁性与第二磁体42412的磁性相反，比如第一磁体42411可以为南极，第二磁体42412可以为北极；或者第一磁体42411可以为北极，第二磁体42412可以为南极。而且第一磁体42411和第二磁体42412沿平行于所述镜头的光 轴方向层叠设置。一个第一导电件4222的一部分与第一磁体42411相对设置，一个第一导电件4222的一部分与第二磁体42412相对设置。以第一导电件4222为环状结构为例，第一导电件4222可以包括沿垂直于镜头440的光轴方西设置的第一部分、第二部分以及沿平行于镜头440的光轴方向设置的第三部分、第四部分，第一部分与第一磁体42411相对设置，第二部分与第二磁体42412相对设置。

其中，另一个第一导电件4222对第二载体4212所产生的推力可以与一个第一导电件4222对第二载体4212所产生的推力相等，使得第二载体4212的两侧受力平衡而以相同的速度上下移动。当然，另一个第一导电件4222对第二载体4212所产生的推力可以与一个第一导电件4222对第二载体4212所产生的推力不相等，从而使得第二载体4212的两侧不平衡而以不同的速度上下移动，进而实现第二载体4212偏转一定的角度。
本申请实施例中，第二磁性件4242的结构可以与第一磁性件4241的结构相同，比如第二磁性件4242可以包括第三磁体42421和第四磁体42422，第三磁体42421的磁性与第四磁体42422的磁性相反，比如第三磁体42421可以为南极，第四磁体42422可以为北极；或者第三磁体42421可以为北极，第四磁体42422可以为南极。而且第三磁体42421和第四磁体42422沿平行于所述镜头的光轴方向层叠设置。另一个第一导电件4222的一部分与第三磁体42421相对设置，另一个第一导电件4222的一部分与第四磁体42422相对设置，具体可参见上述一个第一导电件4222与第一磁性件4241的相关描述，在此不再赘述。

本申请实施例中，第二驱动组件423位于磁性组件424所产生的磁场内，而且第二驱动组件423在磁性组件424的作用下能够带动承载组件421沿垂直于镜头440的光轴方向移动。比如，第二驱动组件423还可以包括第一线圈4232，第一线圈4232在平行于镜头440的光轴方向上与磁性组件424相对设置。基于弗莱明左手定则，第一线圈4232通电之后可以产生一个磁场，第一线圈4232所产生的磁场可以与磁性组件424的磁场相互作用而产生平行于镜头440的光轴方向第二作用力(或者说磁性作用力)，第二作用力作用于承载组件421以带动承载组件421基于滚动结构4231沿垂直于镜头440的光轴方向移动，以补偿镜头440在水平方向上的抖动。
示例性的，结合图4和图12所示，图12为图3所示防抖机构的第六种部分结构示意图。第一线圈可以包括三个，在平行于镜头440的光轴方向上，一个第一线圈4232与第一磁性件4241相对设置以使得该第一线圈4232位于第一磁性件4241所产生的磁场内，该第一线圈4232在通电时可以产生磁场，并于第一磁性件4241所产生的磁场相互作用，并对第一载体4211产生推力，第一载体4211在推力的作用下基于滚动结构4231的滚动操作而带动第二载体4212和导向件4213一起沿垂直于镜头440的光轴方向移动(或者说左右移动)，以补偿镜头440在水平方向上的抖动。
其中，结合图3、图8、图10以及图13所示，图13为图4所示防抖机构中导向件与第一滚珠的配合结构示意图。滚动结构4231可以包括多个第一滚珠42311和多个第二滚珠42312，多个第一滚珠42311和多个第二滚珠42312均设置在承载组件421上，第一线圈4232所产生的第二作用力能够驱动承载组件421基于多个第一滚珠42311沿第一子方向移动，和/或驱动承载组件421基于多个第二滚珠42312沿第二子方向移动，第一子方向和第二子方向均垂直于镜头440的光轴方向，而且第一子方向和第二子方向相互垂直。
可以理解的是，可以将镜头440的移动分解为X、Y和Z方向等三个方向的移动，其中X方向和Y方向同时与Y方向垂直，X方向和Y方向在垂直于Z方向的平面上相互垂直，其中Z方向可以理解为平行于 镜头440的光轴方向，X方向和Y方向可以理解为垂直于镜头440的光轴方向的两个子方向，X方向可以理解为第一子方向，Y方向可以理解为第二子方向。三个第一线圈4232中，与第一磁性件4241相对设置的第一线圈4232以及与第二磁性件4242相对设置的第一线圈4232所产生的第二作用力能够驱动承载组件421基于多个第一滚珠42311沿X方向移动，与第三磁性件4243相对设置的第一线圈4232所产生的第二作用力能够驱动承载组件421基于多个第二滚珠42312沿Y方向移动。
具体地，多个第一滚珠42311设置在导向件4213中背离第一载体4211的一面，多个第二滚珠42312夹设在导向件4213与第一载体4211之间。由此，第一载体4211可基于多个第一滚珠42311相对于底座425在第一子方向(或者说在X方向)上移动，同时带动导向件4213和第二载体4212在第一子方向上移动，从而使得防抖机构420能够在第一子方向上对镜头440进行补偿；和/或第一载体4211可基于多个第二滚珠42312相对于底座425在第二子方向(或者说Y方向)上移动，同时带动导向件4213和第二载体4212在第二子方向移动，从而使得防抖机构420能够在第二子方向上对镜头440进行补偿。
如图13所示，导向件4213沿第一子方向可以开设有多个第一限位槽42133，一个第一滚珠42311容置于一个第一限位槽42133，第一限位槽42133可以对第一滚珠42311的滚动方向进行限制以使得第一滚珠42311仅能沿第一子方向滚动，从而提高防抖机构420在第一子方向上的防抖精度。
如图8和图14所示，图14为图4所示防抖机构中导向件的结构示意图。第一载体4211沿第二子方向可以开设有多个第二限位槽42117，导向件4213靠近第一载体4211的一面开设有多个第三限位槽42134，一个第三限位槽42134与一个第二限位槽42117相对设置，而且相对设置的第二限位槽42117和第三限位槽42134的形状大小相适配，一个第二滚珠42312夹设于一个第二限位槽42117和一个第三限位槽42134之间，一个第二滚珠42312可以与第二限位槽42117的槽底面和槽壁面接触，也可以与第三限位槽42134的槽底面和槽壁面接触，可以提高防抖机构420在第二子方向上的防抖精度。
结合图4以及图7至图9所示，第一载体4211具有相邻设置的凹槽42118和凸出部42119，导向件4213容置于凹槽42118，凸出部42119的外表面与导向件4213的外表面大致齐平。具体地，凹槽42118可以设置在第二侧边42112和第三侧边42113上，凸出部42119可以设置在第一侧边42111和第四侧边42114上。或者说第一侧边42111和第四侧边42114在平行于镜头440的光轴方向上的高度均大于第二侧边42112和第三侧边42113的高度，以在第二侧边42112和第三侧边42113形成凹槽42118，第一侧边42111和第四侧边42114高出第二侧边42112和第三侧边42113的部分形成凸出部42119。导向件4213层叠在第二侧边42112和第三侧边42113上且容置在凹槽42118内，而且导向件4213的外表面与第一侧边42111和第四侧边42114的外表面大致齐平。其中，大致齐平可以理解为在本领域的允许误差内两个外表面齐平。
滚动结构4231还可以包括第三滚珠42313，第三滚珠42313设置在承载组件421上，多个第三滚珠 42313可以使得承载组件421沿第一子方向和/或第二子方向相对于底座425移动。第三滚珠42313设置在凸出部42119上，比如第三侧边42113和第四侧边42114的连接位置可以设置有第四限位槽42119a，第三滚珠42313容置在第四限位槽42119a内且可在第四限位槽42119a内沿第一子方向或者第二子方向滚动。第一线圈4232所产生的第二作用力能够驱动承载组件421基于多个第一滚珠42311和第三滚珠42313沿第一子方向移动，或者驱动承载组件421基于多个第二滚珠42312和第三滚珠42313沿第二子方向移动。
相关技术中的滚珠式驱动马达通常设置有八个滚珠，其中四个滚珠用于实现载体在X方向的移动，另外四个滚珠用于实现载体在Y方向的移动。而本申请实施例通过设置即可沿第一子方向(或者说X方向)滚动又可以沿第二子方向(或者说Y方向)滚动的第三滚珠42313，使得实现第一子方向滚动的多个第一滚珠42311和实现第二子方向滚动的多个第二滚珠42312可以共用一个滚珠，从而相对于相关技术可以节省一颗滚珠，减少防抖机构420的部件，简化防抖机构420的结构。
上盖426与底座425相互连接以在底座425和上盖426之间形成活动空间，承载组件421可移动地容置于活动空间。可以理解的是，承载组件421可以在活动空间内进行上下移动和/或左右移动。多个第一滚珠42311夹设在上盖426和导向件4213之间，使得导向件4213可以相对于上盖426左右移动，第三滚珠42313夹设在上盖426和第一载体4211之间，使得第一载体4211可以相对于上盖426左右移动。
其中，请结合图15，图15为图4所示防抖机构中上盖的结构示意图。上盖426设置有第五限位槽4261和多个第六限位槽4262，第五限位槽4261在平行于镜头440的光轴方向上与第四限位槽42119a相对设置，且两者的形状大小相适配，第三滚珠42313夹设在第四限位槽42119a之间。一个第六限位槽4262在平行于镜头440的光轴方向上与一个第一限位槽42133相对设置，一个第一滚珠42311夹设在一个第一限位槽42133和一个第六限位槽4262之间。
当需要实现镜头440的对焦和/或竖直方向(或者说Z方向)的防抖补偿时，可以通过电路板427给两个第一导电件4222通电，两个第一导电件4222在通电状态下可以产生磁场，其所产生的磁场和第一磁性件4241与第二磁性件4242的磁场相互作用以对第二载体4212产生推力，从而驱动第二载体4212在第一载体4211的收纳空间42115内上下移动，第二载体4212移动时可以带动镜头440上下移动以改变镜头440与感光芯片460之间的距离以实现对焦，镜头440上下移动时也可以补偿镜头440在平行于镜头440的光轴方向上的抖动。
当需要实现镜头440在第一子方向(或者说X方向)上的防抖时，可以通过电路板427给分别与第一磁性件4241与第二磁性件4242相对设置的两个第一线圈4232中的一个或两个通电，该第一线圈4232在通电状态下可以产生磁场，其所产生的磁场和第一磁性件4241和/或第二磁性件4242的磁场相互作用以对第一载体4211产生推力以驱动第一载体4211带动第二载体4212和导向件4213基于多个第一滚珠 42311和第三滚珠42313相对于上盖426和底座425在第一子方向(或者说X方向)上左右移动，第二载体4212移动时可以带动镜头440一起在第一子方向(或者说X方向)上左右移动，从而补偿镜头440在第一子方向上的抖动。
当需要实现镜头440在第二子方向(或者说Y方向)上的防抖时，可以通过电路板427给与第三磁性件4243相对设置的第一线圈4232通电，该第一线圈4232在通电状态下可以产生磁场，其所产生的磁场和第三磁性件4243的磁场相互作用以对第一载体4211产生推力以驱动第一载体4211带动第二载体4212和导向件4213基于多个第二滚珠42312和第三滚珠42313相对于上盖426和底座425在第二子方向(或者说Y方向)上左右移动，第二载体4212移动时可以带动镜头440一起在第二子方向(或者说Y方向)上左右移动，从而补偿镜头440在第二子方向(或者说Y方向)上的抖动。
如图16所示，图16为图2所示摄像头模组中的部分爆炸结构示意图。本申请实施例提供的摄像头模组400中同时具有防抖机构420和防抖模组480，防抖机构420能够驱动镜头440移动以实现镜头440防抖，防抖模组480可以驱动感光元件460移动以实现感光芯片460防抖，即本申请实施例的摄像头模组400具有双防抖功能。相关技术中，通常仅可以实现摄像头防抖或感光芯片防抖等单一防抖功能，然而摄像头防抖或感光芯片防抖等单一防抖结构受电子设备的结构空间限制所能实现的防抖角度有限，仅能实现小角度(诸如1°以内或1.5°以内)的光学防抖功能。本申请实施例的摄像头模组400可以同时实现镜头440防抖和感光元件460防抖，集成镜头440防抖功能以及感光元件460防抖功能，相对于相关技术可以实现更大角度的光学防抖，有效提升摄像头模组400的光学防抖效果。
本申请实施例中，防抖模组480可以包括底板481和形变件482，底板481可以为防抖模组480的其他器件提供支撑，形变件482可以发生形变以带动感光元件460在垂直于镜头440的光轴方向(包括X方向和/或Y方向)上移动，进而实现感光元件460的光学防抖功能。其中，形变件482可以包括固定部分4821和形变部分4822，固定部分4821与底板481固定连接，形变部分4822与感光元件460连接，形变部分4822在通电状态下可发生形变，从而带动感光元件460相对于底板481沿垂直于镜头440的光轴方向移动。可选的，形变件482还可以发生形变以带动感光元件460在垂直于镜头440的光轴方向的平面上，围绕镜头440的光轴方向转动，即形变件482带动感光元件460在X方向和Y方向所在的平面，绕Z方向转动。
其中，形变部分4822可以采用形状记忆合金(shape memory alloys，SMA)制作形成，形状记忆合金在通电状态下可以使得形状记忆合金被加热并使其变形，变形时可以使得形变部分4822的长度发生变化，从而带动与其连接的感光元件460移动，实现感光元件460的防抖功能。
防抖模组480包括突出于底座425的防抖引脚483，底座425对应防抖引脚483设有避让口4252。可以通过防抖引脚483控制形变部分4822的形变，从而控制感光元件460的移动。
为了更好的理解本申请，请结合图17至图19，图17为图1所示电子设备中摄像头模组的另一结构示意图，图18为图17所示摄像头模组AA方向的截面示意图，图19为图17所示摄像头模组BB方向的截面示意图。该摄像头模组可以包括外壳、镜头、感光元件、防抖机构和防抖模组。其中，外壳具有收容空间，比如外壳可以包括上述申请实施例所述的底座425和上盖426，底座425和上盖426连接形成的活动空间为本申请实施例所述的收容空间。镜头、感光元件、防抖机构均容置于收容空间。感光元件在镜头的光轴方向上与镜头相对设置以接收镜头所采集到的光线，具体可参见上述申请实施例中关于镜头440和感光元件460的相关描述，在此不再赘述。防抖机构与镜头连接，防抖机构可以包括两个部分，诸如第一部分和第二部分，第一部分用于驱动镜头沿平行于镜头的光轴方向移动，第二部分用于驱动镜头沿垂直于镜头的光轴方向移动，其中第一部分可以包括但不限于上述申请实施例所述的第一驱动组件422，第二部分可以包括但不限于上述申请实施例所述的第二驱动组件423。防抖模组与感光元件连接，防抖模组用于驱动感光元件沿垂直于镜头的光轴方向移动。其中，防抖模组的具体结构可以参见上述申请实施例所述的防抖模组480，在此不再赘述。
需要说明的是，在一些实施例中，摄像头模组可以仅包括部分驱动结构，诸如第二驱动组件。示例性地，摄像头模组包括感光元件、承载组件和第二驱动组件。感光元件、承载组件和第二驱动组件的具体结构可以参见上述申请实施例所述的感光元件、承载组件和第二驱动组件，在此不再赘述。其中，第二驱动组件包括第一线圈，第一线圈设置在所述承载组件远离感光元件一侧，第一线圈能够驱动承载组件沿垂直于镜头的光轴方向移动。当然，摄像头模组还可以包括其他驱动结构，如还包括第一驱动组件，第一驱动组件设置在所述承载组件上，第一驱动组件用于驱动承载组件沿平行于镜头的光轴方向移动。第一驱动组件的具体结构可以参见上述申请实施例所述的第一驱动组件，在此不再赘述。
可以理解的是，本申请实施例的摄像头模组可以通过防抖机构和防抖模组的设置可以实现镜头和感光元件的双防抖功能，而且其中镜头两个方向的移动可以分别通过防抖机构的两个不同的部分实现，防止由于同一部分同时实现两个方向的移动而导致防抖机构容易损坏的情况发生。
以上对本申请实施例提供的摄像头模组以及电子设备进行了详细介绍。本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请。同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
