后续描述中将以移动终端为例进行说明，本领域技术人员将理解的是，除了特别用于移动目的的元件之外，根据本申请的实施方式的构造也能够应用于固定类型的终端。
本申请提供了一种摄像模组1，应用于移动终端2，请一并参阅图1及图2，图1为实现本申请各个实施例的一种移动终端的硬件结构示意图；图2为图1中沿I-I线的剖视示意图。所述摄像模组1包括第一光学组件11、反射元件12及第二光学组件13，所述第一光学组件11用于将光线聚焦至所述反射元件12，所述光线通过所述反射元件12反射至所述第二光学组件13，所述第二光学组件13用于所述反射元件12反射的光线聚焦至所述移动终端2上的感光模块21。
可选地，所述第一光学组件11及所述第二光学组件13中通常至少包括一个光学透镜，以对入射至所述第一光学组件11或所述第二光学组件13的光线进行聚焦。在本实施方式 中，外界光线入射至所述第一光学组件11，所述第一光学组件11对光线进行聚焦，并入射至所述反射元件12。通过所述反射元件12反射的光线入射至所述第二光学组件13，所述第二光学组件13对光线进行聚焦，并入射至所述移动终端2上的所述感光模块21。可以理解的，最终入射至所述感光模块21的光线的经过了至少两次聚焦，故光线的聚焦倍数应为所述第一光学组件11的聚焦倍数与所述第二光学组件13的聚焦倍数的乘积。
可以理解的，在本实施方式中，所述第一光学组件11及所述第二光学组件13对光线进行多次聚焦，使得最终入射至所述移动终端2的感光模块21的光线聚焦倍数为所述第一光学组件11的聚焦倍数与所述第二光学组件13的聚焦倍数的乘积，大大提高了入射至所述移动终端2感光模块21的聚焦倍数。
可选地，在本实施方式中，所述移动终端2还包括壳体22，如图2所示，所述第二光学组件13及所述反射镜嵌设于所述壳体22内，在减小了所述摄像模组1的占用体积的可选地，由于所述感光模块21通常也设置于所述壳体22内，此种设置方式使得所述第二光学组件13的聚焦出光口可以更好的与所述感光模块21对接。可以理解的，在其他可能的实施方式中，所述第一光学组件11及所述第二光学组件13还可以设置于其他位置，本申请对此不加以限制。
在一种可能的实施方式中，请再次参阅图2，所述摄像模组1还包括至少两个基座12，所述第一光学组件11和所述第二光学组件13分别设置在不同基座14内。
可选地，所述摄像模组1的聚焦倍数是由所述第一光学组件11的聚焦倍数与所述第二光学组件13的聚焦倍数的乘积得到的。可以理解的，在本实施方式中，所述第一光学组件11和所述第二光学组件13分别设置在不同所述基座14内，可以改变所述第一光学组件11的聚焦倍数或所述第二光学组件13的聚焦倍数的乘积，从而改变所述摄像模组1的聚焦倍数，以适应不同的拍摄需求。
在一种可能的实施方式中，请一并参阅图2及图3，图3为本申请一实施方式提供的摄像模组剖视示意图。所述至少两个基座14包括第一基座141、第二基座142和第三基座143，所述第二基座142设于所述第一基座141的一侧，所述第三基座143设置于所述第二基座142背离所述第一基座141的一侧，且所述第三基座143可完全收容于所述第二基座142。
可选地，所述第三基座143可完全收容于所述第二基座142是指，所述第三基座143可沿层叠方向朝向所述第二基座142一侧，或者背离所述第二基座142一侧伸缩。如图3所示，所述第三基座143可伸缩至完全收容于所述第二基座142。
可以理解的，在本实施方式中，所述第三基座143可沿层叠方向朝向所述第二基座142一侧，或者背离所述第二基座142一侧伸缩，从而达到改变所述第一光学组件11的聚焦倍数的效果，以适应不同的拍摄需求。
在一种可能的实施方式中，请再次参阅图2或图3，所述第一光学组件11设置在所述第三基座143内，所述第二光学组件13和所述反射元件12设置在所述第一基座141内。
可选地，如图2或图3所示，所述反射元件12、所述第二光学组件13嵌设于所述移动终端2的所述壳体22内，且所述反射元件12及所述第二光学组件13设置于所述第一基座141内，也就是说，所述第一光学组件11的至少部分也嵌设于所述移动终端2的所述壳体22内。
可以理解的，在本实施方式中，此种设置方式减小了所述摄像模组1的占用体积，可选地，所述反射元件12及所述第二光学组件13还可以用于支撑所述第二基座142及所述第三基座143。
在一种可能的实施方式中，请再次参阅图2或图3，所述第一基座141、所述第二基座142及所述第三基座143分别开设有第一通孔144、第二通孔145及第三通孔146，所述第一通孔144的孔径大于所述第二通孔145的孔径，所述第二通孔145的孔径大于所述第三通孔146的孔径。
可选地，所述第三通孔146的开口位于沿层叠方向背离所述第二基座142的一侧，且所述第二通孔145及所述第一通孔144与所述第三通孔146的开口方向一致。可以理解的，光线经由所述第三通孔146入射至所述聚焦元件111。为了满足所述第三基座143可沿层叠方向朝向所述第二基座142一侧，或者背离所述第二基座142一侧伸缩，所述第二通孔145的孔径大于所述第三通孔146的孔径。
可以理解的，在其他可能的实施方式中，也可以通过设置伸缩组件等其他方式，使得所述第三基座143能够沿层叠方向伸缩，本申请对此不加以限制。
在一种可能的实施方式中，所述第二光学组件13具有第一倍数的定焦功能，可选地，所述第一倍数大于或等于10。
可选地，所述第二光学组件13中具有光学透镜等元件，由于所述第二光学组件13嵌设于所述移动终端2的壳体22内，改变所述第二光学组件13较为困难，故在本实施方式中，不改变所述第二光学组件13的聚焦倍数。
在本实施方式中，当所述第三基座143完全收容于所述第二基座142时，所述摄像模 组1的聚焦倍数为第一倍数；当所述第三基座143由所述第二基座142延伸至最远距离时，所述摄像模组1的聚焦倍数为第二倍数。可选地，所述第二倍数大于所述第一倍数。
可选地，在本实施方式中，以所述第一倍数为10倍，所述第二倍数为100倍为例进行说明。如图3所示，当所述第三基座143完全收容于所述第二基座142时，所述第一光学组件11的聚焦倍数为1倍，根据所述第一光学组件11的聚焦倍数与所述第二光学组件13的聚焦倍数的乘积，则所述摄像模组1的聚焦倍数为10倍。如图2所示，当所述第三基座143由所述第二基座142延伸至最远距离时，所述第一光学组件11的聚焦倍数为10倍，根据所述第一光学组件11的聚焦倍数与所述第二光学组件13的聚焦倍数的乘积，则所述摄像模组1的聚焦倍数为100倍。
可以理解的，在本实施方式中，所述第三基座143由最远距离逐渐向所述第二基座142收缩时，所述第一光学组件11的聚焦倍数将逐渐由10倍减小至1倍。因此，根据所述第三基座143由所述第二基座142向外延伸的距离，所述摄像模组1的聚焦倍数可以实现由10倍-100倍不同的变化。
在一种可能的实施方式中，请一并参阅图4，图4为本申请另一实施方式提供的摄像模组剖视示意图。所述第一光学组件11还包括聚焦元件111和转动模块112，所述转动模块112与所述聚焦元件111连接，所述转动模块112用于带动所述聚焦元件111转动。
需要说明的是，由于所述聚焦元件111设置于所述第三基座143，当所述聚焦元件111与所述反射元件12的距离改变时，所述第一光学组件11的聚焦倍数将发生变化。因此，如图2所示，当所述第三基座143由所述第二基座142完全延伸而出时，所述聚焦元件111距离所述反射元件12的距离最大，此时所述第一光学组件11的聚焦倍数最大；如图3所示，当所述第三基座143完全收容于所述第二基座142时，所述聚焦元件111距离所述反射元件12的距离最小，此时所述第一光学组件11的聚焦倍数最小。
可以理解的，所述转动模块112带动所述聚焦元件111转动，可以实现所述第一光学组件11的追焦功能。所谓的追焦功能是指，当用于发射光线的光源3移动时，所述转动模块112可以带动所述聚焦元件111转动，从而使得光线仍能够以较好的角度入射至所述聚焦元件111，从而聚焦至所述反射元件12。
可选地，请一并参阅图5-图7，图5为本申请一实施方式提供的光源位置示意图；图6为本申请另一实施方式提供的光源位置示意图；图7为本申请另一实施方式提供的光源位置示意图。可选地，如图5所示，光源3位于所述聚焦元件111的右侧，则所述转动模块 112带动所述聚焦元件111向右侧倾斜；如图6所示，光源3位于所述聚焦元件111的中间，则所述转动模块112带动所述聚焦元件111居中；如图7所示，光源3位于所述聚焦元件111的左侧，则所述转动模块112带动所述聚焦元件111向左侧倾斜。可以理解的，以上设置方式使得光源3发出的光线能够以更好的角度入射至所述聚焦元件111，从而实现所述第一光学组件11的追焦功能。
可以理解的，在其他可能的实施方式中，光源3位置还可以位于其他位置，只要不影响所述转动模块112带动所述聚焦元件111转动至更好的角度，本申请对此不加以限制。
在一种可能的实施方式中，请再次参阅图4，所述转动模块112包括第一磁性组件1121、第一线圈1122、第二磁性组件1123及第二线圈1124，所述第一磁性组件1121及所述第二磁性组件1123分别设置于所述聚焦元件111的两侧，且所述第一磁性组件1121夹设所述第一线圈1122，所述第二磁性组件1123夹设所述第二线圈1124，当所述第一线圈1122通电时，所述聚焦元件111向所述第一磁性组件1121一侧倾斜转动；当所述第二线圈1124通电时，所述聚焦元件111向所述第二磁性组件1123一侧倾斜转动。
可选地，在本实施方式中，可以通过在所述第三基座143内的多个位置设置感光元件，例如光敏电阻等，从而确定光源3(见图5-图7)入射至所述第三基座143的光线的方向。可选地，光源3由所述聚焦元件111的左侧向右侧移动时，位于所述第三基座143内的感光元件感受到的光线强度应与光源3移动的方向相反，即所述第三基座143内感光元件感受到的光线强度值由右侧较大逐渐变为左侧较大。可选地，向位于所述聚焦元件111右侧的所述第二线圈1124通电，使得所述第二磁性组件1123产生磁性，从而带动所述聚焦元件111向所述第二磁性组件1123一侧倾斜转动，实现所述第一光学组件11的追焦功能。
可选的，在本实施方式中，所述第一磁性组件1121及所述第二磁性组件1123分别设置于所述聚焦元件111垂直于层叠方向上的两侧，以更好的带动所述聚焦元件111倾斜转动。
可以理解的，在其他可能的实施方式中，还可以是其他方式实现所述第一光学组件11的追焦功能，本申请对此不加以限制。
在一种可能的实施方式中，请再次参阅图5-图7，当所述转动模块112带动所述聚焦元件111转动时，所述转动模块112还用于带动所述反射元件12转动，且所述反射元件12转动的方向与所述聚焦元件111转动的方向相同。
可选地，如图5-图7所示，当所述光源3的位置发生改变时，所述光源3入射至所述反射元件12的光线角度也随之发生变化。可以理解的，所述反射元件12转动的方向与所 述聚焦元件111转动的方向相同，可以使得所述聚焦元件111聚焦的光线以更好的角度入射至所述反射元件12。
可选地，在本实施方式中，所述转动模块112还可以包括电机，并与所述反射元件12相连接，用于带动所述反射元件12转动。在其他可能的实施方式中，所述转动模块112还可以以其他方式带动所述反射元件12转动，本申请对此不加以限制。
本申请还提供了一种移动终端2，请一并参阅图8，图8为本申请一实施方式提供的移动终端框架示意图。所述移动终端2包括如上文所述的摄像模组1及感光模块21，经过所述摄像模组1聚焦后的光线入射至所述感光模块21的感光面，所述感光模块21用于将光信号转换为电信号。
可选地，所述移动终端2通常还包括处理器23，所述感光模块21将光信号转换为电信号，并发送至所述处理器23，所述处理器23可根据所述电信号实现不同的功能，例如在移动终端2上显示拍摄的画面等。所述摄像模组1的具体结构参照上述实施例，由于本移动终端可以采用上述任一实施例的任一技术方案，说明书拓展和解释内容与上述各实施例基本相同，在此不再一一赘述。
上述本申请实施例序号仅仅为了描述，不代表实施例的优劣。本申请实施例设备中的单元可以根据实际需要进行合并、划分和删减。在本申请中，对于相同或相似的术语概念、技术方案和/或应用场景描述，一般只在第一次出现时进行详细描述，后面再重复出现时，为了简洁，一般未再重复阐述，在理解本申请技术方案等内容时，对于在后未详细描述的相同或相似的术语概念、技术方案和/或应用场景描述等，可以参考其之前的相关详细描述。在本申请中，对各个实施例的描述都各有侧重，某个实施例中没有详述或记载的部分，可以参见其它实施例的相关描述。
本申请技术方案的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本申请记载的范围。
