背景技术
随着终端功能的不断发展，摄像头已成为手机、平板电脑等终端产品中不可缺少的电子器件。目前手机、平板电脑等终端为了实现拍照功能和视频通话功能，需要在终端上安装前置摄像头和后置摄像头。
虽然安装前置摄像头和后置摄像头实现了终端的拍照功能和视频通话功能，但是存在以下问题：前置摄像头和后置摄像头均需要独立的摄像头组件制作，如感光器、镜头、印制电路板和连接器等，导致制造复杂、终端成本较高；前后置摄像头的两套摄像头组件需要分别占据独立的空间位置，从而减少了终端的其他器件的空间位置，导致终端的空间利用率较低；基于终端成本的考虑，通常前置摄像头的像素、变焦调节、光学防科等性能远低于后置摄像头，前置摄像头的性能较差。

实施例一
图1-图4是本公开一个实施例的摄像头模组的结构示意图。参照图1-图4可知，本公开实施例提供的摄像头模组包括：模组支架1和驱动装置(未标出)，以及设置于模组支架1内的第一反光镜2、第二反光镜3和镜头组件4；模组支架1的第一侧壁上设置有第一进光口a、第二侧壁上设置有第二进光口b，第一侧壁和第二侧壁相对设置如平行设置；
第一反光镜2设置在第一进光口a处，第一反光镜2的镜面与第一侧壁呈第一预设角度；第二反光镜3设置在第二进光口b处，第二反光镜3的镜面与垂直于第一侧壁的第一水平面呈第二预设角度；镜头组件4设置在垂直于第一侧壁的第二水平面上，镜头组件4的镜头面向第二反光镜3的镜面；
第二反光镜3与驱动装置连接，驱动装置控制第二反光镜3绕镜头组件4的中心轴旋转，当第二反光镜3的镜面面向第一反光镜2时，通过第一进光口a的光线依次经过第一反光镜2和第二反光镜3的反射，最终传输至镜头组件4；当第二反光镜3的镜面面向第二进光口b时，通过第二进光口b的光线经过第二反光镜3的反射，最终传输至镜头组件4。
模组支架1还可以设置有第三侧壁，第三侧壁与上述的第一水平面平行，镜头组件4可以设置在第三侧壁上。
第一反光镜2的镜面和第二反光镜3的镜面可以为多种形状，如圆形，长方形、正方形等。第一反光镜2的镜面尺寸可以与第一进光口a的尺寸匹配，也可以大于第一进光口a的尺寸；同理，第二反光镜3的镜面尺寸可以与第二进光口b的尺寸匹配，也可以大于第二进光口b的尺寸。
在组件支架1内放置第一反光镜2和第二反光镜3时，第一反光镜2的中心点与第二反光镜3的中心点的连线可以分别与第一进光口a的轴线、第二进光口b的轴线以及镜头组件4的中心轴垂直相交；当镜面尺寸大于进光口尺寸时，第一反光镜2的中心点与第二反光镜3的中心点的连线可以不与第一进光口a的轴线相交，通过第一进光口a的光线照射到第一反光镜2的一侧而非中心区域，同理通过第二进光口b的光线可以照射到第二反光镜3的一侧而非中心区域。反光镜的上述放置位置均可实现本公开实施例所述的光线传输，可以根据实际对反光镜的放置位置进行设置。
如图1-图4所示，如果第二反光镜3面向第二进光口b时，则可以将第二反光镜3绕镜头模组4的中心轴旋转90°，使第二反光镜3面向第一反光镜2，从而实现摄像头模组的功能切换。
摄像头模组中，第一反光镜2的镜面与第一侧壁呈第一预设角度，第二反光镜3的镜面与垂直于第一侧壁的第一水平面呈第二预设角度，可以根据具体情况对第一预设角度和第二预设角度进行设置。具体地，第一预设角度可以为45°，第二预设角度可以为45°。
模组支架可以为多种结构，如L型结构。当模组支架为L型结构时，第一反光镜2和第二反光镜3可以位于水平支架内，镜头组件4位于竖直支架内。
驱动装置与第二反光镜3连接，控制第二反光镜3旋转。具体地，第二反光镜可以固定在一支撑结构上，如三角形支架，支撑结构与驱动装置的旋转轴连接，当驱动装置控制旋转轴旋转时，旋转轴带动第二反光镜3旋转。
通过模组支架、两个反光镜、镜头组件以及驱动装置多个部件之间的位置设置和部件连接，实现了镜头组件交替对通过第一进光口的光线和通过第 二进光口的光线的采集，使摄像头模组交替具有前置摄像头功能和后置摄像头功能，摄像头模组在各方向上具有相同的且高质量的成像效果，同时具有结构简单、制造复杂度低、集成度高、产品良率高、做货周期短、成本低、便于调试和维修等优点。
图5-图8是本公开一个实施例的摄像头模组在使用前置摄像头功能时的结构示意图，图5-图8中箭头方向为光线传输方向。
参照图5-图8，将第一进光口a设置为终端的前置取景框，摄像头模组在该结构下具有前置摄像头功能。第二反光镜3面向第一反光镜2，光线通过第一进光口a后，依次经过第一反光镜2和第二反光镜3的反射，最终将光线反射至镜头组件4，使得镜头组件4获取到第一进光口a所采集的图像。
将第二进光口b设置为终端的后置取景框，摄像头模组在该结构下具有后置摄像头功能。当第二反光镜3旋转至面向第二进光口b时，通过第二进光口b的光线经过第二反光镜3的反射最终传输至镜头组件4。通过第二进光口b的光线经过一次反射最终传输至镜头组件4。
图9-图12是本公开一个实施例的摄像头模组在使用后置摄像头功能时的结构示意图，图9-图12中箭头方向为光线传输方向。参照图9-图12，将第二进光口b设置为终端的后置取景框，摄像头模组在该结构下具有后置摄像头功能。第二反光镜3面向第二进光口b和镜头组件4，光线通过第二进光口b后最终反射至镜头组件4，使得镜头组件4获取到第二进光口b所采集的图像。
安装有上述摄像头模组的终端如移动终端、具有前后摄像头功能。如果将第一进光口a作为前置取景框，将第二进光口b作为后置取景框，则将第一进光口a可以设置于移动终端的显示屏侧，将第二进光口b可以设置在移动终端的终端后盖侧。
本公开实施例提供的摄像头模组在不同结构时交替具有前置摄像头功能和后置摄像头的功能，摄像头模组在各方向上具有相同的成像效果，具有结构简单、制造复杂度低、集成度高、产品良率高、做货周期短、成本低、便 于调试和维修等优点。
相比于相关技术中因造价过高而省去一个摄像头模组的装配，致使产品功能减少的问题，基于本公开实施例提供的摄像头模组的结构，只需将本公开实施例提供的一个摄像头模组安装在终端内，即可交替实现终端的前置摄像头功能和后置摄像头功能，大大降低了终端的制造成本，具有结构简单、空间利用率高等上述优点。
由于第一表面和第二表面相对设置，因此第一进光口和第二进光口不在同一平面上，符合将前置摄像头和后置摄像头安装在终端壳体两侧的设计观念，符合现阶段对终端的外观需求。
本公开实施例还提供了一种上述的摄像头模组的控制方法。图13是本公开一个实施例的摄像头模组的控制方法的流程图，参照图13，所述方法可以包括以下步骤：
步骤101、使用驱动装置控制第二反光镜旋转至第一旋转位置，使第二反光镜面向第一反光镜，使用镜头模组采集通过第一进光口的光线。
本公开实施例提供的摄像头模组包括第一反光镜和第二反光镜，第二反光镜与驱动装置连接，驱动装置控制第二反光镜的旋转。通过控制驱动装置控制第二反光镜旋转，让第二反光镜面向第一反光镜，这时通过第一进光口的光线会先被第一反光镜反射至第二反光镜，光线再经过第二反光镜的反射作用最终反射至镜头组件，使得镜头组件采集通过第一进光口的光线，获取到第一进光口采集的图像。
步骤102、使用驱动装置控制第二反光镜旋转至第二旋转位置，使第二反光镜面向第二进光口，使用镜头模组采集通过第二进光口的光线。
通过控制驱动装置控制第二反光镜旋转，让第二反光镜面向第二进光口，这时通过第二进光口的光线会被第二反光镜反射至镜头组件，使得镜头组件采集通过第二进光口的光线，获取到第二进光口采集的图像。
操作中，所述使用镜头模组采集通过所述第一进光口的第一光线的步骤 可以包括：使用第一反光镜将通过第一进光口的光线反射至第二反光镜，使用第二反光镜将经第一反光镜反射的光线反射至镜头模组。所述使用镜头模组采集通过第二进光口的光线的步骤可以包括：使用第二反光镜将通过第二进光口的光线反射至镜头模组。
本公开实施例中，第一旋转位置与第二旋转位置之间的夹角可以为90°，这时驱动装置可以通过控制第二反光镜旋转90°，实现前后摄像头功能的切换。
依据本公开实施例提供的控制方法，实现了上述摄像头模组的控制，实现镜头组件对通过第一进光口的光线和通过第二进光口的光线的采集，实现终端的前置摄像头功能和后置摄像头功能。
本公开实施例还提供了一种移动终端。移动终端包括本公开实施例提供的摄像头模组。移动终端可以为多种，如手机、平板电脑、笔记本等。
安装有上述摄像头模组的移动终端具有以下优点：成本降低，普通的前置摄像头和后置摄像头需要两个摄像头模组，本公开提供的移动终端为单个摄像头模组，仍可实现前后置摄像头的功能，减小了摄像头模组的数目，大大降低了终端成本；空间结构优化，节省了一个摄像头模组的空间应用，便于布置更多的器件应用，在一定程度上降低了终端厚度；性能提升：前置摄像头可以达到与后置摄像头同样的性能指标，如分辨率、光学防抖等，另外节省出的空间可以增加镜头数目，达到多倍的光学变焦；效率提升：依据传统的设计需要，印制电路板需要预留前置摄像头与后置摄像头的连接器的位置，在装机过程中，需要分别完成前置摄像头、后置摄像头的安装工作，在测试过程中，需要分别完成前置摄像头、后置摄像头的测试工作，使用本公开提供的移动终端后，可以简化上述操作过程，操作效率如装机效率、测试效率等得到大幅度提升。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
