可以理解的是，镜头212的光轴方向可以是第一方向H1，该第一方向H1可以是竖直方向，例如是坐标轴中的Z轴方向。垂直于镜头212的光轴方向可以是第二方向H2，该第二方向H2可以是水平面内的任一水平方向，例如是坐标轴中的X轴方向或Y轴方向。围绕镜头212的光轴方向，可以是垂直于镜头212的光轴的平面内的任一方向，例如是坐标轴中的XOY平面内的任一方向。

可以理解的是，防抖机构214除了驱动图像传感器213沿垂直于镜头212的光轴方向移动或者围绕镜头212的光轴方向转动外，还可以驱动图像传感器213以其他的方式运动，例如，防抖机构214还可以驱动图像传感器213沿镜头212的光轴方向上下运动；或者，防抖机构214还可以驱动图像传感器213围绕垂直于镜头212的光轴方向翻转。本申请实施例对防抖机构214驱动图像传感器213运动的具体方式不进行限定。

可以理解的是，第二防抖组件220除了驱动第一防抖组件210围绕垂直于镜头212的光轴方向翻转外，还可以驱动第一防抖组件210以其他的方式运动，例如，第二防抖组件220还可以驱动第一防抖组件210沿镜头212的光轴方向上下运动，或者第二防抖组件220还可以驱动第一防抖组件210沿垂直于镜头212的光轴方向移动或者围绕镜头212的光轴方向转动。本申请实施例对第二防抖组件220驱动第一防抖组件210运动的具体方式不进行限定。

基于光学防抖技术，电子设备10(或摄像模组200)的陀螺仪或加速度计 等传感器可以检测到镜头212的抖动以生成抖动信号，并将该抖动信号传递至电子设备10和/或摄像模组200的处理芯片，电子设备10和/或摄像模组200的处理芯片可以计算出防抖机构214、第二防抖组件220需要补偿的位移量，以使得防抖机构214、第二防抖组件220可以根据镜头212的抖动方向及其位移量对镜头212进行补偿，从而改善或摄像模组200因用户在使用过程中发生抖动而产生的成像效果。
相关技术中，通常仅可以实现摄像头防抖或图像传感器213防抖等单一防抖功能，然而摄像头防抖或图像传感器213防抖等单一防抖结构受电子设备10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。并且，相关技术中通过驱动摄像头或图像传感器213翻转时，摄像头或图像传感器213之间的相对角度发生偏转，二者相互不平行，此时图像传感器213不易通过摄像头采集到清晰的图像。
而本申请实施例的摄像模组200，第一防抖组件210的防抖机构214可以驱动图像传感器213运动，防抖机构214可以实现图像传感器213的防抖功能；第二防抖组件220可以驱动整个第一防抖组件210运动并使镜头212和图像传感器213运动，第二防抖组件220可以实现图像传感器213和镜头212的防抖功能，从而，本申请实施例的第二防抖组件220和防抖机构214相配合可以实现摄像模组200的多功能防抖。例如，当第一防抖组件210的防抖机构214驱动图像传感器213沿垂直于镜头212的光轴方向移动或围绕镜头212的光轴方向转动，防抖机构214可以驱动图像传感器213实现X轴平移、Y轴平移、XOY平面转动的三轴防抖功能；第二防抖组件220驱动整个第一防抖组件210翻转而实现镜头212和图像传感器213围绕垂直于镜头212的光轴方向翻转，第二防抖组件220可以驱动镜头212和图像传感器213以XOY平面内的第一轴线L1、第二轴线L2进行翻转运动，第二防抖组件220和防抖机构214相配合可以实现摄像模组200的五轴防抖功能，摄像模组200可以实现多种抖动场景下的防抖补偿，摄像模组200的适应性更优。
并且，本申请实施例的摄像模组200，第二防抖组件220带动整个第一防抖组件210翻转，第二防抖组件220不需要受限于第一防抖组件210内部的空间，第二防抖组件220可以设置更大的行程，第二防抖组件220可以带动镜头212和图像传感器213实现大角度的翻转防抖补偿，第二防抖组件220可以大幅度改善摄像模组200在抖动状态下的图像质量，提高摄像模组200的拍照体验；而且， 第二防抖组件220同时带动镜头212和图像传感器213翻转，镜头212和图像传感器213之间依然可以保持平行而不发生相对偏转，在防抖补偿的过程中，图像传感器213可以清晰地采集穿过的镜头212的光线，而使得图像传感器213形成的图像不易模糊、图像更清晰。

其中，定位座221上可以设有至少两个滑槽2211。至少两个滑槽2211可以位于垂直于镜头212的光轴方向的一条轴线上例如第一轴线L1上，至少两个滑槽2211可以关于该第一轴线L1的中心点O(也可以是第一轴线L1与镜头212的光轴的交点)对称设置。此时，滚动结构2221可以包括至少两个滚动子结构，以使得每一滚动子结构可以限位于一个滑槽2211内。当滚动结构2221在滑槽2211内运动时，对称设置的两个滚动子结构可以对称地对第一防抖组件210施加作用力，相较于仅只有一个滚动子结构施加作用力的方案而言，本申请实施例的第一驱动机构222可以提高驱动第一防抖组件210翻转的稳定性。
可以理解的是，定位座221上还可以设有至少四个滑槽2211，至少两个滑槽2211可以位于垂直于镜头212的光轴方向的一条轴线上例如第一轴线L1上并关于第一轴线L1的中心点O对称设置，至少另外两个滑槽2211可以位于垂直于镜头212的光轴方向的另一条轴线上例如第二轴线L2上并关于第二轴线L2的中心点O对称设置，该第一轴线L1和第二轴线L2可以是XOY平面内的两条交叉的对角线。相应的，滚动结构2221可以至少包括四个滚动子结构，以使得每一滚动子结构可以限位于一个滑槽2211内。此时，第一驱动机构222通过至少四个滑槽2211和至少四个滚动子结构，可以驱动第一防抖组件210沿第一轴线L1翻转或沿第二轴线L2翻转，第二防抖组件220可以实现摄像模组200的双轴线翻转。

可以理解的是，滑槽2211也可以不为轴对称结构，此时，第一驱动机构222可以带动第一防抖组件210顺时针或逆时针翻转不同的角度。本申请实施例对 滑槽2211的具体结构不进行限定。
考虑到第二驱动机构223提供的驱动力的方向问题，该滑槽2211除了包括球形槽外，还可以包括与球形槽连通的其他槽体段，例如但不限于直槽段。当第二驱动机构223为第一驱动机构222提供驱动力时，滚动结构2221可以先沿直槽段运动一定距离后进入球形槽内，然后带动第一防抖组件210翻转运动。可以理解的是，该直槽段的尺寸可以较小，以使得第一防抖组件210沿直槽段的运动可以忽略。

可以理解的是，当对一个或多个形变件2144进行通电、或者对一个或多个形变件2144传输不同大小的电流时，一个或多个形变件2144的长度可以发生变化而使得与多个形变件2144连接的第一载体2142或第二载体2143平移，以使得图像传感器213也可以平移。
示例性的，当第一载体2142上的端部为固定不变的端部而第二载体2143上的端部为可产生形变的端部时，若对第一形变件21441通电使其变长时(和/或对第三形变件21443通电使其变短，以下形变变化可以参考该状态而不再赘述)，第一形变件21441可带动第一载体2142和图像传感器213沿Y轴方向向前平移；若对第三形变件21443通电使其变长时，第三形变件21443可带动第一载体2142和图像传感器213沿Y轴方向向后平移；若对第二形变件21442通电使其变长时，第一形变件21441可带动第一载体2142和图像传感器213沿X轴方向向右平移；若对第四形变件21444通电使其变长时，第四形变件21444可带动第一载体2142和图像传感器213沿X轴方向向左平移；若同时对第一形变件21441和第三形变件21443通电使其变长时，第一形变件21441可带动第一载体2142和图像传感器213沿对角线L3在XOY平面内顺时针转动；若同时对第一形变件21441和第三形变件21443通电使其变短时，第一形变件21441和第三形变件21443可带动第一载体2142和图像传感器213沿对角线L3在XOY平面内逆时针转动；若同时对第二形变件21442和第四形变件21444通电使其变长时，第二形变件21442和第四形变件21444可带动第一载体2142和图像传感器213沿对角线L4在XOY平面内顺时针转动；若同时对第二形变件21442和第四形变件21444通电使其变短时，第二形变件21442和第四形变件21444可带动第一载体2142和图像传感器213沿对角线L4在XOY平面内逆时针转动。
可以理解的是，防抖机构214还可以包括一个或多个支撑件2146，每一支撑件2146可以位于第一载体2142和第二载体2143之间，每一支撑件2146可以设置于第一载体2142或第二载体2143上，每一支撑件2146可以将第一载体2142和第二载体2143间隔，以使得第一载体2142和第二载体2143之间具有一定的间隙，一方面，多个形变件2144发生形变时不易与第一载体2142和第二载体2143接触，可以避免第一载体2142和第二载体2143对形变件2144的形变干扰；另一方面，当第一载体2142和第二载体2143上设有金属结构时，也可以防止第一载体2142和第二载体2143接触而短路。
本申请实施例的防抖机构214通过SMA马达实现图像传感器213的水平移 动及水平面转动，相较于其他的结构而言，防抖机构214通过形变件2144的形变特性实现图像传感器213的驱动，防抖机构214不需要设置磁力驱动、电机驱动等结构，防抖机构214的结构更简单，占用的空间更小。其中，请再次参考图1至图4，防抖机构214还可以包括柔性电路板模组2145，该柔性电路板模组2145可以围设且连接于第一载体2142的边缘，柔性电路板模组2145可与图像传感器213电连接以为其供电。当图像传感器213在多个形变件2144的带动下运动时，柔性电路板的形态也可以产生变化，以适应图像传感器213的运动。并且，柔性电路板模组2145可与第一载体2142和底板2141形成吊篮结构，该吊篮结构可使底板2141与后盖2112之间可以存在0.1和0.5毫米的运动空间，以便于防抖机构214运动。
其中，请参考图11，图11为图10所示的防抖机构的一种电连接示意图。摄像模组200还可以包括控制芯片例如第一控制芯片230，该第一控制芯片230可以但不限于设置在柔性电路板模组2145上，第一控制芯片230可以与防抖机构214电连接，第一控制芯片230可以监控防抖机构214的运动参数，第一控制芯片230可以根据监控防抖机构214的运动参数与摄像模组200的抖动参数来实时控制防抖机构214的摆动，以便于防抖机构214的抖动补偿更精准，实现防抖机构214的闭环控制。
其中，本申请实施例的第一防抖组件210还可以包括对焦机构215。请结合图1至图4并请参考图12，图12为本申请实施例提供的对焦机构215的一种结构示意图。对焦机构215可以与镜头212连接，对焦机构215可以驱动镜头212沿镜头212的光轴方向移动。
对焦机构215可以位于外壳211形成的容置空间内，对焦机构215可以在镜头212的光轴方向与防抖机构214相对设置，对焦机构215和防抖机构214可以沿第一方向H1层叠设置。在一些实施例中，对焦机构215可以包括第二承载件2151和驱动件，该第二承载件2151可以承载镜头212，第二承载件2151可以但不限于是镜头212载体。驱动件可以包括弹性结构2152，该弹性结构2152与第一防抖组件210的外壳211连接，弹性结构2152可以沿镜头212的光轴方向设置在第二承载件2151上并与第二承载件2151连接，弹性结构2152可以被配置为采用弹性作用力能够使得第二承载件2151能沿镜头212的光轴方向移动，从而弹性结构2152可使第二承载件2151和镜头212沿第一方向H1移动，以实现镜头212的对焦操作。
可以理解的是，弹性结构2152可以包括上簧片21521和下簧片21522，上簧片21521的一部分可以与第二承载件2151连接、另一部分可以与第一防抖机构214的外壳211连接；下簧片21522的一部分可以与第二承载件2151连接、另一部分可以与第一防抖机构214的外壳211连接。当弹性结构2152驱动第二承载件2151沿第一方向H1上下移动时，上簧片21521和下簧片21522与外壳211连接的部分可以对第二承载件2151施加一牵引力，以使得第二承载件2151可以稳定的停留在某一位置处，从而实现第二承载件2151和镜头212的精准对焦。
如图12所示，对焦机构215还可以包括第二磁性件2153和第二导电件2154。第二磁性件2153可以产生第二磁场，第二承载件2151可以位于第二磁场内。第二导电件2154可在垂直于镜头212的光轴方向上与第一磁性件2231相对设置，第二导电件2154在第二磁性件2153的作用下可以产生第二作用力，第二作用力和弹性结构2152产生的弹性作用力可以共同使第二承载件2151沿镜头212的光轴方向移动。
可以理解的是，第二磁性件2153可以但不限定是永磁铁、电磁铁等可以产生磁场的磁性元件。第二磁性件2153可以设置在第二承载件2151上。第二导电件2154可以但不限于是线圈结构，外部电源可以为线圈通电，以使得第二导电件2154可以在第二磁性件2153的作用下产生驱动第二承载件2151沿第一方向H1上下移动的作用力。
可以理解的是，弹性结构2152还可以与第二导电件2154电连接，例如下簧片21522可以与第二导电件2154电连接，外部电源可以通过下簧片21522为第二导电件2154供电。在一些实施例中，外部电源的电能可以通过柔性电路板模组2145与下簧片21522电连接并传输电能。
可以理解的是，第二磁性件2153可以包括一个或多个子磁性件。例如，第二磁性件2153可以包括四个子磁性件，四个子磁性件可以均匀间隔地围绕镜头212的光轴方向分布在第二承载件2151的周围。相应的，第二导电件2154也可以对应包括多个子导电件，以使得每一子导电件可以与有一个子磁性件相对设置。本申请实施例对第二磁性件2153和第二承载件2151的具体结构不进行限定。
本申请实施例的对焦机构215通过第二磁性件2153和第二导电件2154相互配合可以使第二承载件2151和镜头212沿竖直方向上下运动，对焦机构215结构简单、占据的空间较小，可以实现摄像模组200的小型化设计。
需要说明的是，本申请实施例的对焦机构215、防抖机构214和第二防抖组 件220的具体结构并不局限于上述实施例的说明。对焦机构215、防抖机构214、第二防抖组件220的结构可以相互借鉴并相互组合，以实现对焦机构215、防抖机构214、第二防抖组件220的不同运动形式。例如，防抖机构214、第二防抖组件220还可以如对焦机构215一样设置弹性结构2152、第二磁性件2153、第二导电件2154等部件，以实现沿镜头212的光轴光线上下运动。再例如，防抖机构214、对焦机构215还可以如第二防抖组件220一样设置滑槽2211、滚动结构2221等部件，以实现围绕垂直于镜头212的光轴方向翻转。又例如，对焦机构215和第二防抖组件220还可以如防抖机构214一样设置形状记忆合金式马达而实现沿垂直于镜头212的光轴方向移动或围绕镜头212的光轴方向转动。本申请实施例对对焦机构215、防抖机构214和第二防抖组件220的具体结构不进行限定。
需要说明的是，在本申请的描述中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
