下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的摄像头模组进行详细地说明。
请参考图1～图11，本申请实施例公开一种摄像头模组，所公开的摄像头模组应用于电子设备。所公开的摄像头模组包括第一模组壳体100、第二模 组壳体200、第一支架300、第一转动件、第二转动件、第三转动件、驱动机构600和摄像头主体400。
第二模组壳体200为摄像头模组的第一模组壳体100和其他组成部件提供安装基础。第二模组壳体200开设有第二内腔，第一模组壳体100位于第二内腔中。
第一模组壳体100开设有第一内腔，第一支架300的至少部分设置在第一内腔中。摄像头主体400的至少部分可以设置在第一内腔中，摄像头主体400通过第一支架300与第一模组壳体100相连接。
第一转动件设置于第一支架300与摄像头主体400之间，第一支架300与摄像头主体400通过第一转动件转动连接。驱动机构600可通过第一转动件驱动摄像头主体400沿第一轴线转动。
第二转动件设置于第一支架300与第一模组壳体100之间，第一支架300与第一模组壳体100通过第二转动件转动连接。驱动机构600驱动第一支架300沿第二轴线转动。此时，当驱动机构600驱动第一支架300沿第二轴线转动时，第一支架300与摄像头主体400相对固定，因此摄像头主体400可以随第一支架300一起沿第二轴线转动。
第一模组壳体100与第二模组壳体200通过第三转动件转动相连。驱动机构600可通过第三转动件驱动第一模组壳体100沿第三轴线转动。此时，当驱动机构600驱动第一模组壳体100沿第三轴线转动时，第一支架300和摄像头主体400相对于第一模组壳体100固定，因此摄像头主体400可以随着第一模组壳体100沿第三轴线一起转动。
第三轴线与第一平面相交，第一平面为第一轴线和第二轴线所在的平面。此时，第一轴线和第二轴线可以相平行，也可以相交。
本申请公开的实施例中，摄像头主体400相对于第一支架300沿第一轴线转动，摄像头主体400和第一支架300形成的整体相对于第一模组壳体100沿第二轴线转动，摄像头主体400、第一支架300和第一模组壳体100形成的整体相对于第二模组壳体200沿第三轴线转动。由于第三轴线与第一轴线 和第二轴线所在的平面相交，因此摄像头主体400在上述三个方向的转动能够补偿摄像头模组抖动造成的倾斜在这三个方向的角度分量，最终能够对摄像头模组实施有效防抖，进而提高摄像头模组的图像拍摄质量。
另外，在摄像头主体400在三个方向转动，因此摄像头模组能够实现更大视场的拍摄。
在另一种可选的实施例中，第一轴线、第二轴线和第三轴线两两相交。此方案中，摄像头主体400相对于第一支架300的转动方向、第一支架300相对于第一模组壳体100的转动方向以及第一模组壳体100相对于第二模组壳体200的转动方向均不一致。此方案能够增大摄像头模组防抖的角度，进一步提高摄像头模组的拍摄性能。
优选地，第一轴线、第二轴线和第三轴线两两相垂直，此种情况下，在拍摄的过程中摄像头模组的抖动产生的倾斜角度容易分解成为沿第一轴线、第二轴线以及第三轴线的三个角度分量，从而在这三个方向摄像头主体400在转动过程中进行角度补偿。
第一轴线可以为摄像头模组其中一条对角线，第二轴线可以为摄像头模组的另一条对角线，第三轴线可以为摄像头模组的光轴。此时，第一模组壳体100、第一支架300和摄像头主体400沿摄像头模组的光轴转动，由于实际摄像头模组的感光芯片通常为长方体，当摄像头模组发生抖动时，摄像头模组的焦点以及光线的透射方向可能会发生偏斜，因此，摄像头主体400沿摄像头模组的光轴转动能够使得摄像模组的焦点和光线的透射方向不容易发生倾斜，进一步提高了摄像头模组的拍摄质量。
在本申请实施例中，第一模组壳体100的结构可以由多种，请再次参考图1，一种具体的实施例中，第一模组壳体100可以包括第一框架110、第一顶板120和第一底板130，第一顶板120设置在第一框架110的一端的端口上，第一底板130可以设置在第一框架110的另一端的端口上。第一框架110、第一顶板120和第一底板130形成第一内腔，第一顶板120上开设有第一避让孔121，第一避让孔121与第一内腔相连通。上述结构的第一模组壳体100 具有良好的可装配性，方便摄像头主体400的安装。
可选地，第一框架110和第一顶板120可以采用卡接、粘接或者焊接等方式连接，第一框架110和第一底板130也可以采用卡接、粘接或者焊接等方式连接。或者在一种具体的实施例中，第一框架110与第一顶板120卡接，第一框架110与第一底板130一体成型。此时，第一框架110与第一底板130一体成型无需装配，第一支架300和摄像头主体400可以通过第一框架110的一端的端口装入第一框架110内，然后在盖上第一顶板120，从而完成装配。
在本申请实施例中，第二模组壳体200的结构可以由多种，请再次参考图1，一种具体的实施例中，第二模组壳体200可以包括第二框架210、第二顶板220和第二底板230，第二顶板220可以设置在第二框架210的一端的端口上。第二底板230可以设置在第二框架210的另一端的端口上，第二框架210、第二顶板220和第二底板230形成第二内腔，第二顶板220上开设有第二避让孔221，第二避让孔221可以与第二内腔相连通。上述结构的第二模组壳体200具有良好的可装配性，方便摄像头模组的安装。
第二模组壳体200也可以采用第一模组壳体100的结构，因此本文不再赘述。
进一步地，上述的第一避让孔121与上述的第二避让孔221可以相对分布。此时，摄像头模组可以通过第一避让孔121和第二避让孔221伸出至第一模组壳体100和第二模组壳体200之外，从而使得第一模组壳体100和第二模组壳体200不容易与摄像头主体400发生干涉，进而方便摄像头模组的组装。
为了提高第一模组壳体100和第二模组壳体200的转动性能，在另一种可选的实施例中，第三转动件可以设置于第一底板130和第二底板230之间。第三转动件可以包括一个中心滚珠510和多个边缘滚珠520，中心滚珠510的中心与第三轴线相重合，多个边缘滚珠520可以环绕中心滚珠510设置。此时，中心滚珠510和边缘滚珠520与第一模组壳体100和第二模组壳体200 的接触面积较小，从而使得中心滚珠510和边缘滚珠520与第一模组壳体100和第二模组壳体200之间的摩擦力较小，进而提高了第一模组壳体100和第二模组壳体200的转动性能。
进一步地，第一底板130和第二底板230中，一者可以设置有第一定位孔，另一者可以开设有滑槽540，滑槽540的延伸方向与第一模组壳体100的转动方向相同。滑槽540和第一定位孔的数量与边缘滚珠520的数量均相同。第一定位孔与边缘滚珠520限位配合。边缘滚珠520的部分可以位于滑槽540内，滑槽540与边缘滚珠520可以滑动配合。可选地，滑槽540可以为直条状滑槽，也可以是弧形滑槽。此外，滑槽540的横截面可以是矩形，当然，也可以是等边梯形或者是圆弧形，从而进一步减小边缘滚珠520与滑槽540之间的摩擦力。
此方案中，滑槽540和第一定位孔能够对边缘滚珠520的位置进行辅助限位，从而防止边缘滚珠520发生移位，进而使得第一模组壳体100的转动轴线不容易发生偏移，使得摄像头模组的防抖性能更好。
上述实施例中，中心滚珠510也容易发生偏移，为此，在另一种可选的实施例中，第一底板130和/或第二底板230上可以开设有第二定位孔550，中心滚珠510的部分可以位于第二定位孔550内。第二定位孔550与中心滚珠510可以限位配合。此方案中，第二定位孔550能够对中心滚珠510的位置进行限制，从而防止中心滚珠发生偏移。
上述实施例中，第一顶板120和第二顶板220可以直接接触，此时，第一顶板120与第二顶板220的接触面积较大，因此导致第一模组壳体100和第二模组壳体200在转动的过程中容易发生卡涩等现象。
基于此，在另一种可选的实施例中，本申请公开的摄像头模组可以设置有顶紧滚珠530，顶紧滚珠530可以设置于第二顶板220与第一顶板120之间。此方案中，此时，顶紧滚珠530与第一模组壳体100和第二模组壳体200的接触面积较小，从而使得顶紧滚珠530与第一顶板120和第二顶板220之间的摩擦力较小，进而提高了第一模组壳体100和第二模组壳体200的转动 性能。
另外，顶紧滚珠530能够对第一顶板120施加预压力，进而使得第一模组壳体100在第二内腔中不容易发生晃动，进而提高了第一模组壳体100和第二模组壳体200的装配可靠性。
上述实施例中，顶紧滚珠530也容易发生偏移，为此，在另一种可选的实施例中，第一顶板120或第二顶板220可以开设有第三定位孔560，第三定位孔560和顶紧滚珠530一一对应，顶紧滚珠530的部分可以位于第三定位孔560内。此方案中，第三定位孔560能够对顶紧滚珠530的位置进行限制，从而防止顶紧滚珠530发生偏移。
在另一种可选的实施例中，第一顶板120或者第二顶板220可以开设有第一通孔222和第二通孔223，顶紧滚珠530可以位于第一通孔222和第二通孔223之间。此方案中，第一顶板120或者第二顶板220在靠近顶紧滚珠530顶靠的区域附近开设有两个通孔，从而使得顶紧滚珠530顶靠的区域能够发生弹性变形，从而使得顶紧滚珠530更加可靠地位于第一顶板120和第二顶板220之间。另外，顶紧滚珠530顶靠的区域能够发生弹性变形，进而使得顶紧滚珠530的尺寸精度可以设置的较低，因此降低摄像头模组的制造成本。
可选地，第一通孔222可以为条形孔，条形孔的延伸方向为第二模组壳体200的外侧指向第二模组壳体200的内侧的方向。当然第一通孔222也可以为其他结构，本文不作限制。第二通孔223的结构可以和第一通孔222的结构相同，本文不再赘述。
在另一种可选的实施例中，摄像头主体400可以包括摄像头410和第二支架420，第二支架420可以环绕摄像头410设置，第一支架300与第二支架420可以通过第一转动件相连。此时，摄像头410与第二支架420固定连接，第一支架300与第二支架420通过第一转动件转动相连，摄像头410随第二支架420一起转动。此方案中，第二支架420环绕摄像头410设置，第二支架420能够用于保护摄像头410，从而使得摄像头410在转动的过程中 不容易与摄像头模组的其他部件发生磕碰，进而使得提高摄像头模组的可靠性和安全性。
可选地，第二支架420可以为环形板件，第二支架420上可以开设有第一安装孔，从而用于安装下文中的磁铁组件620，进而减小电子设备的体积。第二支架420的相对的两侧开设有避让豁口，第一支架300的部分能够从避让豁口伸入第一模组壳体100内，并与第一模组壳体100相连接。当然，第二支架420还可以为其他结构，本文不作限制。
在另一种可选的实施例中，驱动机构600可以包括线圈组件610和磁铁组件620，线圈组件610和磁铁组件620可以相对设置，线圈组件610和磁铁组件620可以用于驱动摄像头模组、第一支架300和第一模组壳体100转动。
通电后的线圈在磁场中会受到安培力，当线圈组件610位于磁铁组件620形成的磁场内时，受到安培力的作用，安培力能够驱动摄像头主体400、第一支架300和第一模组壳体100转动，摄像头模组的受力方向可以根据左手定则判断，左手定则为公知技术，因此本文不再赘述。
此方案中，驱动机构600中的零部件较少，因此使得摄像模组的结构简单，驱动机构600占用摄像模组的安装位置较小，从而使得摄像模组的体积较小。
另外，驱动机构600中通过改变线圈组件610的电流方向，从而实现摄像头主体400的换向，进而使得摄像头主体400换向灵活，提高摄像头模组的防抖性能。
能够达到相应驱动功能的结构很多，比如通过活塞机构实现的气压传动机构或者液压传动机构，又或者是丝杠传动机构、齿轮齿条类传动机构等，这些传动机构均能够驱动摄像头主体400、第一支架300和第一模组壳体100转动，又或者，采用形状记忆合金结构件，通过其自身形状复位来实现驱动摄像头主体400、第一支架300和第一模组壳体100转动。
在一种具体的实施例中，线圈组件610可以包括第一线圈、第二线圈和 第三线圈，磁铁组件620可以包括第一磁铁、第二磁铁和第三磁铁。第一线圈、第二线圈和第三线圈沿第一模组壳体100的周向间隔分布。第一磁铁和第二磁铁可以位于摄像头主体400的相邻两侧，第三磁铁位于设置于第二模组壳体200，且第三磁铁与第一磁铁或者第二磁铁相对设置。
第一线圈与第一磁铁相对设置，第一线圈在通电的情况下，第一线圈和第一磁铁驱动摄像头主体400沿第一轴线转动。
第二线圈与第二磁铁相对设置，第二线圈在通电的情况下，第二线圈和第二磁铁驱动第一支架300沿第二轴线转动。
第三线圈与第三磁铁相对设置，第三线圈在通电的情况下，第三线圈和第三磁铁驱动第一模组壳体100沿第三轴线转动。
此方案中，相对应的磁铁和线圈能够产生磁场力，进而能够驱动相应的构件发生旋转，从而使得摄像头模组的结构简单。
为了进一步简化摄像头模组的结构，在另一种可选的实施例中，本申请公开的摄像头模组还包括电路板800，第一线圈、第二线圈和第三线圈可以均设置于电路板800，并与电路板800电连接。此时，电路板800用于控制第一线圈、第二线圈和第三线圈通电。此方案中，第一线圈、第二线圈和第三线圈采用同一电路板800连接，从而无需为各个线圈单独配置电路板800，因此使得摄像头模组的结构更加简单紧凑。
可选地，电路板800可以包括依次连接的第一折弯段、第二折弯段和第三折弯段，第一线圈可以设置于第一折弯段，第二线圈可以设置于第二折弯段，第三线圈可以设置于第三折弯段，第一折弯段、第二折弯段和第三折弯段分别贴设在第一模组壳体100的三个面上。当然，电路板800还可以为其他结构，本文不作限制。
为了进一步减小摄像头模组的体积，第一模组壳体100的表面还可以开设有第二安装孔，第二安装孔用于安装线圈组件610，从而可以将线圈组件610容纳于第二安装孔内，进而可以减小摄像头模组的体积。
在另一种可选的实施例中，本申请公开的摄像头模组还可以包括至少一 个检测元件700，至少一个检测元件700可以设置于电路板800，检测元件700用于检测摄像头主体400的偏移角度。此方案中，检测元件700可以对摄像头主体400的偏振角度进行实时测量，从而保证摄像头模组的防抖效果。检测元件700可以是霍尔芯片，当然，还可以为其他类型的芯片，本文不作限制。
可选地，电路板800上还可以设置有控制芯片810，控制芯片810与电路板800电连接，控制芯片810可根据陀螺仪或者检测元件700的检测信号控制线圈组件610的电流，从而在不同区域产生不同强度的磁场，进而摄像头模组产生适当转动以抵消外部抖动带来的影响。
具体的操作过程中，当电子设备或者摄像头模组内部的陀螺仪检测到摄像模组倾斜，陀螺仪将获取摄像头模组的倾斜角度等数据传输给控制芯片810，控制芯片810输入相应的角度补偿量，控制芯片810输出对应的电流，从而控制相应的线圈通电，进而驱动摄像头主体400转动。
在摄像头模组转动时，检测元件700能够对摄像头主体400的偏移角度进行检测，检测信号能够反馈至控制芯片810，从而对摄像头主体400的偏转角度进行修正。
具体地，检测元件700的数量可以为三个，三个检测元件700分别对应安装在对应线圈的中心位置。此时每个检测元件700能够对对应的方向的偏转进行检测，从而提高了检测的精度。
第一支架300的结构可以有多种。在一种可选的实施例中，第一支架300可以包括支架主体310、第一连接臂320和第二连接臂330，第一连接臂320的一端与支架主体310固定相连，第一连接臂320的另一端与摄像头主体400通过第一转动件转动连接，第二连接臂330的一端与支架主体310固定相连，第二连接臂330的另一端与第一模组壳体100可以通过第二转动件连接。此方案中，第一连接臂320和第二连接臂330为悬臂结构，第一连接臂320和第二连接臂330可以分别伸入第一支架300和第一模组壳体100内，从而更有利于整体摄像头模组的小型化设计。
为了进一步提高摄像头模组的连接稳定性，在另一种可选的实施例中，第一连接臂320和第二连接臂330可以均为两个，两个第一连接臂320成一对角分别分布在摄像头主体400的两侧，两个第二连接臂330成另一对角分别分布在摄像头主体400的两侧。此种情况下，每个第一连接臂320可以与一个第一转动件转动连接，每个第二连接臂330可以与一个第二转动件转动连接，这无疑能够提高转动支撑的均衡性。
可选地，第一连接臂320和第二连接臂330均朝向第一内腔的一侧折弯，此时第一连接臂320和第二连接臂330伸入第一内腔中，因此第一连接臂320和第二连接部不容易外露，进而使得第一连接臂320和第二连接臂330不容易受到破坏，提高了第一支架300的使用寿命。
为了提高摄像头主体400和第一支架300的转动性能，在另一种可选的实施例中，第一转动件可以包括两个第一滚珠，两个第一滚珠可以位于摄像头主体400和第一支架300之间，且两个第一滚珠可以沿第一轴线分布，也可以关于第一轴线对称分布。此方案中，第一滚珠与摄像头主体400和第一支架300的接触面积较小，从而使得第一滚珠与摄像头主体400和基座之间的摩擦力较小。同时，第一滚珠与摄像头主体400和第一支架300均可以实现滚动配合，从使得摄像头主体400与第一支架300之间转动更加灵活，进而使得摄像头主体400和第一支架300的转动性能更好。
此外，第一转动件还可以为滚柱，滚柱与摄像头主体400和第一支架300均可以实现滚动配合。
为了提高第一模组壳体100和第一支架300的转动性能，第二转动件可以包括两个第二滚珠，两个第二滚珠可以位于第一支架300与第一模组壳体100之间，且两个第二滚珠可以沿第二轴线分布，也可以关于第二轴线对称分布。此方案中，第二滚珠与第一模组壳体100和第一支架300的接触面积较小，从而使得第二滚珠与第一模组壳体100和第一支架300之间的摩擦力较小。同时，第一滚珠与第一模组壳体100和第一支架300均可以实现滚动配合，从使得第一模组壳体100与第一支架300之间转动更加灵活，进而使 得第一模组壳体100和第一支架300的转动性能更好。
此外，第二转动件还可以为滚柱，滚柱与第一模组壳体100和第一支架300均可以实现滚动配合。
