(5)常规膝上型和/或掌上型无线电电话收发器等。
参考图1，在一些实施方式中，终端设备10为智能手机，终端设备10包括摄像头模组100和壳体200，摄像头模组100设置于壳体200，摄像头模组100可用于执行拍摄功能。例如，在一些实施方式中，摄像头模组100能够执行前置摄像头的功能，用户可以通过摄像头模组100进行自拍、视频通话等操作。在另一些实施方式中，摄像头模组100能够执行后置摄像头的功能，用户可以通过摄像头模组100进行近景拍摄、远景拍摄、视频录制等操 作。在其他实施方式中，终端设备10可以为平板电脑、笔记本电脑等。本发明以智能手机的摄像头模组100为例进行说明，但可以理解的是，本发明公开的摄像头模组100，对于其他类型的终端设备10也是适用的。
参考图2，摄像头模组100采用了潜望式摄像头方案，即摄像头模组100的入光面101与摄像头模组100的光轴103的延伸方向不是相互垂直的关系。例如，参考图1，终端设备10包括相背设置的显示面201和背面203，显示面201可用于显示信息并为用户提供交互界面。摄像头模组100从终端设备10的背面203入光，摄像头模组100的光轴103与终端设备10的厚度方向垂直，因此在光轴103的延伸方向上，摄像头模组100可以具有相对较大的长度和宽度，以获得较长的焦距，并获得更好的拍摄质量。这种结构的摄像头模组100，其内部可以提供相对较大的空间供透镜移动，进而可以实现光学变焦功能，以获得更好的拍摄质量，并适应更多样的拍摄场景。
具体地，参考图2，摄像头模组100包括座体110、反射元件120、透镜组130、图像传感器140和驱动结构150，反射元件120、透镜组130分别安装于座体110并被座体110支撑，反射元件120用于摄像头模组100的入光，环境光线能够入射至反射元件120，并被反射元件120反射至透镜组130，穿过透镜组130的光线可以进一步入射至图像传感器140，以将环境光信号转化为电信号，经过进一步的处理后即可形成被拍摄物的图像。光轴103由透镜组130确定，且光轴103的延伸方向与反射元件120的入光面101平行或者成锐角。驱动结构150包括流体元件151和挤压元件153，挤压元件153安装于座体110，图像传感器140连接流体元件151，挤压元件153能够挤压流体元件151以驱使流体元件151变形，进而带动图像传感器140运动。
摄像头模组100进一步包括电路板160，电路板160连接座体110，流体元件151连接电路板160并位于图像传感器140和电路板160之间。电路板160与图像传感器140电性连接，电路板160可以设置柔性线路板，并通过柔性线路板电性连接至终端设备10的主板，以将摄像头模组100采集的图像数据传输至终端设备10的处理器作进一步的处理。进一步，摄像头模组100 包括滤光元件170，滤光元件170安装于座体110且位于透镜组130和图像传感器140之间。滤光元件170能够过滤红外光，以使摄像头模组100能够获得更好的拍摄质量。
在一些实施方式中，反射元件120大致呈三棱柱状，且反射元件120为棱镜并包括反射面121，反射面121能够对入射光线产生全反射。全反射的设置，使得入射光经由反射元件120后的损失较小，有利于获得更好的拍摄质量。在其他实施方式中，反射元件120为棱镜且包括反射面121，反射面121镀有反射膜以使入射至反射面121的光线产生全反射。在这种实施方式中，反射膜为光学膜且加工较为容易，因而可以降低对棱镜的材质要求，在降低摄像头模组100的制造成本的同时，获得相对较高的拍摄质量。
流体元件151包括外壳和流体，外壳为柔性体且包覆流体，流体可以为液体或者气体或者气液混合物且被外壳密封。外壳可以采用粘接或者其他连接方式连接至图像传感器140，以在流体元件151变形时带动图像传感器140运动。挤压元件153包括压电陶瓷件、磁致伸缩件中的任一种。具体地，压电陶瓷件在电场作用下尺寸会发生变化，因此可以通过控制电场使挤压元件153对流体元件151施加挤压力；磁致伸缩件在磁场作用于下可以产生伸缩变形，因此可以通过采用电磁铁等结构控制磁场使挤压元件153对流体元件151施加挤压力。在一些实施方式中，挤压元件153包括电磁铁和永磁铁，电磁铁与座体110的位置相对固定，永磁铁则可以相对座体110移动，在电磁铁通电产生磁场时，可以驱使永磁铁移动并挤压流体元件151。当然，挤压元件153也可以包括永磁铁和线圈，永磁铁固定设置于座体110并用于提供磁场，线圈连接座体110并设于磁场中且在通电时能够移动以挤压流体元件151。
参考图3和图4，在一些实施方式中，挤压元件153挤压流体元件151使流体元件151变形时，图像传感器140能够沿光轴103平移以靠近或远离透镜组130。具体地，参考图5，在这种实施方式中，挤压元件153包括两个第一挤压元件153a，且两个第一挤压元件153a相背设置于流体元件151的 两端。两个第一挤压元件153a可以相互独立控制，也可以同步控制，以使两个第一挤压元件153a同时产生相等的位移，进而使得图像传感器140在光轴103的延伸方向产生平移运动。这种结构的摄像头模组100，由于挤压元件153能够挤压流体元件151，进而驱使图像传感器140平移，因而可以实现对焦功能。例如，当物距发生变化时，基于成像原理1/f＝1/u+1/v(其中f为镜头焦距，u为物距，v为相距)可知，像距也应当相应发生改变，通过驱动结构150即可调整图像传感器140的位置，进而满足对焦的需求。参考图5，在一些实施方式中，第一挤压元件153a和第二挤压元件153可以关于光轴103呈中心对称布置。在其他实施方式中，第一挤压元件153a的数量可以在2个以上，以更便捷、精确地控制流体元件151的变形，且驱动结构150的可以获得相对较快的响应。由于流体元件151的变形较容易控制，采用相对较小的挤压力即可实现流体的变形，因而挤压元件153可以具有相对较低的功耗，并且挤压元件153的结构可以相对简单、制造也较为容易，且占用的体积可以相对较小，以使驱动结构150能够提供相对较大的位移并利于实现摄像头模组100的小型化设计，进而有利于终端设备10的轻薄化设计。
进一步，结合图3和图6，在一些实施方式中，挤压元件153挤压流体元件151使流体元件151变形时，图像传感器140能够产生偏转。具体地，参考图5和图6，两个第一挤压元件153a能够分别独立控制，以此为例，其中一个第一挤压元件153a挤压流体元件151时，另一个可以不挤压流体元件151，或者两个第一挤压元件153a对于流体元件151的挤压位移不相等，图像传感器140即可产生偏转。这种结构的摄像头模组100，由于挤压元件153能够挤压流体元件151，进而驱使图像传感器140偏转，因而可以实现防抖功能，以在摄像头模组100产生抖动时仍然可以获得清晰的拍摄图像。例如，终端设备10包括陀螺仪，通过陀螺仪可以检测终端设备10的抖动量，在终端设备10产生抖动时，驱动结构150可以根据抖动量对图像传感器140进行补偿，以获得清晰的拍摄图像。同样地，这种防抖的方式也可以获得相对较快的响应，并有利于摄像头模组100和终端设备10的轻薄化设计。
当两个第一挤压元件153a关于光轴103呈中心对称地设置于流体元件151的两端时，两个第一挤压元件153a可以驱使图像传感器140绕第一轴偏转，进而实现摄像头模组100在第一轴的防抖。当然，第一挤压元件153a可以设置2个以上，以实现更精确的控制。进一步，参考图7，挤压元件153包括两个能够相互独立控制的第二挤压元件153b，且两个第二挤压元件153b与两个第一挤压元件153a交替并间隔设置于流体元件151的周向，两个第二挤压元件153b相背设置。第二挤压元件153b的结构和工作原理可以和第一挤压元件153a相似，两个第二挤压元件153b也可用于摄像头模组100的对焦。进一步，两个第二挤压元件153b可以驱使图像传感器140绕第二轴偏转，进而实现摄像头模组100在第二轴的防抖。第一轴与第二轴可以相互垂直，也可以呈锐角。
以第一轴与第二轴相互垂直为例，相邻第一挤压元件153a和第二挤压元件153b关于光轴103的圆心角相等。例如，在第一挤压元件153a为两个、第二挤压元件153b为两个的实施方式中，相邻第一挤压元件153a与第二挤压元件153b的圆心角为90度，这种设置能够较为便捷地控制驱动结构150，以实现摄像头模组100在第一轴和第二轴的防抖功能，进而获得更好的防抖效果。终端设备10的陀螺仪可以检测终端设备10的抖动量，并在终端设备10产生抖动时，根据抖动量在第一轴和第二轴分别对图像传感器140进行补偿，以获得清晰的拍摄图像。同样地，这种防抖的方式也可以获得相对较快的响应，并有利于摄像头模组100和终端设备10的轻薄化设计。
上述摄像头模组100，挤压元件153可以挤压流体元件151，以使流体元件151产生变形，进而带动图像传感器140运动，图像传感器140的运动即可实现摄像头模组100的对焦或者防抖功能。驱动结构150具有相对较小的体积、结构较为简单，且流体的变形易于控制，因而能够在相对较低的功耗下较为容易地控制图像传感器140的运动，以获得更快的对焦速度或者更好的防抖效果。上述驱动结构150对于大体积的透镜和大面积的图像传感器140同样适用，且有利于简化摄像头模组100的结构、缩小摄像头模组100的体 积并降低摄像头模组100的功耗。
进一步，在一些实施方式中，摄像头模组100包括音圈马达，音圈马达设置于座体110且能够驱动透镜组130移动。具体地，音圈马达包括线圈和磁铁，线圈连接透镜组130，磁铁连接座体110并用于提供磁场，在线圈通电时即可驱使透镜组130移动。进一步，音圈马达可以驱使透镜组130中的单个或多个透镜沿光轴103方向移动，进而实现光学变焦功能。
