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。
镜头212和图像传感器213可以沿第一方向H1上下层叠设置,镜头212与图像传感器213可以相互平行。镜头212的材质可以是玻璃或塑胶等。镜头212主要用于改变光线的传播路径,并对光线进行聚焦。镜头212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212时,多组镜片层层过滤杂光(例如红外光),以便于增加摄像模组200的成像效果。图像传感器213可以但不限于是电荷耦合元件(Charge Coupled Device,简称CCD)、互补金属氧化物半导体(Complementary Metal Oxide Semiconductor,简称CMOS)等类型的影像传感器。图像传感器213主要用于接收来自镜头212采集的光线,并将光信号转化为电信号,以便于实现摄像模组200的成像需求。

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。

可以理解的是,第一端部21425至第四端部21428可以是固定不变的端部而第五端部21435至第八端部21438可以是在外力作用下产生形变的端部;或者,第五端部21435至第八端部21438可以是固定不变的端部而第一端部21425至第四端部21428可以是在外力作用下产生形变的端部。从而,每一形变件2144的一端可以连接固定不动的端部而另一端连接可形变的端部。当然,第一至第八端部21438也可以均是在外力作用下产生形变的端部,此时没有形变件2144的两端均可以连接可形变的端部。本申请实施例对第一至第八端部21438的具体特性不进行限定。
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。

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。

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。
