请参阅图4和图5，定焦镜头23与图像传感器22相对应定焦镜头23包括第一镜筒231、第二镜筒232、第一镜片组233和第二镜片组234。
第一镜筒231设置在外壳21内且能够相对外壳21沿定焦镜头23的光轴L方向移动。第一镜片组233安装在第一镜筒231内且与第一镜筒231固定连接。在第一镜筒231相对外壳21沿光轴L移动时，第一镜筒231带动第一镜片组233沿光轴L移动。也即是说，第一镜筒231和第一镜片组233均可相对图像传感器22沿光轴L移动。
第一镜片组233包括至少一个镜片235，在图4和图5所示的实施方式中，第一镜片组233包括多个镜片235，多个镜片235的类型可以一致也可不一致，例如，多个镜片235均可为凸透镜或者凹透镜或者多个镜头中的部分为凸透镜，另一部分为凹透镜，一部分为球面镜，另一部分为非球面镜，具体在此不作限制。

也即是说，在本申请的实施方式中，第一镜筒231和第一镜片组233的运动与第二镜筒232和第二镜片组234的运动是相互不干涉的，两者均可自由的相对图像传感器22沿光轴L方向运动，同时，两者也可在光轴L方向上相对运动。
第二镜片组234也包括至少一个镜片235，在图4和图5所示的实施方式中，第一镜片组233也包括多个镜片235，多个镜片235的类型可以一致也可不一致，例如，多个镜片235均可为凸透镜或者凹透镜或者多个镜头中的部分为凸透镜，另一部分为凹透镜，一部分为球面镜，另一部分为非球面镜，具体在此不作限制。
此外，在本申请的实施方式中，第一镜筒231可与外壳21滑动连接。第二镜筒232可套设在第一镜筒231内，第二镜筒232和第一镜筒231也滑动连接，从而与第一镜筒231共同形成可伸缩式的定焦镜头23。当然，在一些实施方式中，第二镜筒232也是位 于第一镜筒231外，第二镜筒232和第一镜筒231分别于外壳21滑动连接。
需要指出的是，在本申请的描述中，例如以上的描述的“第一镜片组”、“第二镜片组”中，术语“第一”、“第二”仅用于描述目的，并不能指示定焦镜头仅具有两个镜片组，也不能暗示第一镜片组比第二镜片组重要，或者说，术语“第一”、“第二”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。此外，在本申请的描述中，需要理解的是，术语“内”、“外”指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
可以理解，在一些实施方式中，定焦镜头23也还可包括第三镜片组或者更多的镜片组，多个镜片组可以是设置在第一镜片组233和第二镜片组234之前或者之后或者之间。在这样的实施方式中，除第一镜片组233和第二镜片组234可以沿光轴L移动外，其它的镜片组也能够沿光轴L移动或者是部分能够沿光轴L移动或者是均不能移动，具体在此不作限制。
请一并参阅图4至图7，在本实施方式中，第一镜片组233和第二镜片组234能够沿光轴L向远离图像传感器22所在一侧运动以使得定焦镜头23从第一位置A运动至第二位置B(从图4和图6所示的位置运动至图5和图7所示的位置)。定焦镜头23在处于第二位置B时的长度大于定焦镜头23在处于第一位置A时的长度。在定焦镜头23处于第一位置A时，定焦镜头23收纳在电子装置100的壳体10内，在定焦镜头23处于第二位置B时，定焦镜头23至少部分地伸出壳体10。第一镜筒231和第二镜筒232均可由驱动组件30驱动，也即是说，在本申请的实施方式中，驱动组件30连接第一镜片组233和第二镜片组234，驱动组件30用于驱动第一镜片组233和第二镜片组234运动以使定焦镜头23在第一位置A和第二位置B之间运动。
具体地，请参阅图4和图6，在定焦镜头23处于第一位置A时，定焦镜头23的第一镜片组233靠近图像传感器22，第二镜片组234靠近第一镜片组233，第一镜片组233和图像传感器22之间的间隔较小，第二镜片组234和第一镜片组233之间的也间隔较小。此时，第一镜片组233、第一镜筒231、第二镜片组234和第二镜筒232均位于摄像组件的外壳21内，或者说第一镜片组233、第一镜筒231、第二镜片组234和第二镜筒232均位于电子装置100的壳体10内(如图2所示)。在这样的情况下，由于第一镜片组233和图像传感器22之间的间隔较小，第二镜片组234和第一镜片组233之间 的间隔较小，定焦镜头23和摄像模组20的总长较短。
这样，相对于为了增加像素和分辨率而使得镜头的总长，从而使得电子装置的机身越来越厚的技术方案来说，在本申请中，在定焦镜头23处于第一位置A时的状态下将摄像模组20安装在电子装置100的壳体10内可以避免增加壳体10的厚度，有利于电子装置100的轻薄化。在需要拍摄时，只需驱动第一镜片组233和第二镜片组234运动从而使得定焦镜头23伸出电子装置100的壳体10外以运动至第二位置B以使得摄像模组20在图像传感器22上对焦即可实现正常摄像功能。
此外，在本申请的实施方式中，第一镜片组233和第二镜片组234单独封装，这样，相对于为了增加像素和分辨率而采用较多的镜片一起封装的技术方案来说，本申请采用的多级镜片组单独封装可以减少每个镜片组需要封装的镜片235的数量，降低了镜头的组装难度，提高了镜头的组装良率。
可以理解的是，在本申请的实施方式中，在定焦镜头23处于第一位置A时，摄像模组20在图像传感器22外对焦。也即是说，在定焦镜头23处于第一位置A时，图像传感器22无法正常成像，摄像模组20无法进行正常的拍摄功能。“摄像模组20在图像传感器22外对焦”可以理解为图像传感器22采集的图像不是最清晰的物像，最清晰的物像所在的平面位于图像传感器22所处的平面外。
在需要使用摄像模组20进行正常拍摄时，可通过驱动组件30驱动第一镜片组233和第二镜片组234沿光轴L向远离图像传感器22所在一侧运动以使得定焦镜头23从第一位置A运动至第二位置B。在定焦镜头23处于第二位置B时，摄像模组20在图像传感器22上对焦，从而使得图像传感器22能够采集到清晰的图像。也即是说，在本申请的实施方式中，第一位置A可以理解为第一镜片组233和第二镜片组234向图像传感器22所在的一侧运动至极限位置时定焦镜头23所处的位置，此时定焦镜头23的长度最短(如图4所示)。摄像模组20无法正常对焦。可以理解的是，在本文中，“摄像模组20在图像传感器22上对焦”可以理解为图像传感器22可以采集到最清晰的物像。第二位置B可以理解为在第一镜头组和第二镜头组沿光轴L远离图像传感器22所在的一侧运动至摄像模组20刚好能够在图像传感器22上对焦时，定焦镜头23所处的位置(如图5所示)。也即是说，在定焦镜头23处于第一位置A或者是处于第一位置A与第二位置B之间的任意位置时，摄像模组20都是在图像传感器22外对焦而无法获得清晰的物像。
请参阅图4至图7，在定焦镜头23从第一位置A向第二位置B运动的过程中，第一镜片组233与图像传感器22之间的间距逐渐增大。第二镜片组234与第一镜片组233之间的间距也逐渐增大。也即是说，在这样的实施方式中，在在定焦镜头23从第一位 置A向第二位置B运动的过程中，第一镜片组233逐渐远离图像传感器22，第二镜片组234逐渐远离第一镜片组233。
在图5所示的实施方式中，在定焦镜头23处于第二位置B时，第一镜片组233收纳在壳体10内，第二镜片组234至少部分地伸出壳体10。也即是说，在装配电子装置100时，摄像模组20的定焦镜头23处于第一位置A，摄像模组20安装在电子装置100的壳体10内，第一镜片组233和第二镜片组234均完全收纳在壳体10内。在需要摄像模组20进行拍摄时，可通过驱动组件30驱动第一镜片组233和第二镜片组234运动从而使得第一镜片组233至少部分地伸出至电子装置100的壳体10外。可以理解的是，在一些实施方式中，在定焦镜头23处于第二位置B时，也可以是第一镜片组233和第二镜片组234均伸出壳体10，也即，第一镜片组233和第二镜片组234均完全伸出壳体10或者是第二镜片组234完全伸出壳体10，第一镜片组233部分地伸出壳体10，具体在此不作限制。
请参阅图8，在本实施方式中，驱动组件30连接第一镜片组233和第二镜片组234，驱动组件30用于驱动第一镜片组233和第二镜片组234运动以使定焦镜头23从第一位置A运动至第二位置B。具体第，驱动组件30可包括第一驱动机构31和第二驱动机构32，第一驱动机构31连接第一镜片组233，第一驱动机构31用于驱动第一镜片组233沿光轴L运动，第二驱动机构32连接第二镜片组234，第二驱动机构32用于驱动第二镜片组234沿光轴L运动。
在申请的实施方式中，第一驱动机构31和第二驱动机构32均可包括电机和齿轮齿条传动结构，齿条可沿光轴L方向固定连接在第一镜筒231和第二镜筒232上，电机的电机轴连接齿轮或者齿轮组，齿轮或者齿轮组与齿条啮合。电机带动齿轮转动从而带动齿条和第一镜筒231和第二镜筒232沿光轴L方向移动，从而实现第一镜片组233和第二镜片组234的移动。在一些实施方式中，第一驱动机构31和第二驱动机构32也可通过丝杆螺母的方式对第一镜片组233和第二镜片组234进行驱动。
另外，在某些实施方式中，第一驱动机构31和第二驱动机构32也可为电磁驱动机构、压电驱动机构或记忆合金驱动机构。
具体地，电磁驱动机构中包括磁场与导体，如果磁场相对于导体运动，在导体中会产生感应电流，感应电流使导体受到安培力的作用，安培力使导体运动起来，此处的导体为电磁驱动机构中带动第一镜片组233和第二镜片组234移动。压电驱动机构，基于压电陶瓷材料的逆压电效应：如果对压电材料施加电压，则产生机械应力，即电能与机械能之间发生转换，通过控制其机械变形产生旋转或直线运动，具有结构简单、低速的优点。
记忆合金驱动机构的驱动基于形状记忆合金的特性：形状记忆合金是一种特殊的合金，一旦使它记忆了任何形状，即使产生变形，但当加热到某一适当温度时，它就能恢复到变形前的形状，以此达到驱动的目的，具有变位迅速、方向自由的特点。
可以理解的是，在本申请的实施方式中，第一驱动机构31和第二驱动机构32的驱动方式可以相同也可以不相同，具体在此不作限制。
下面，对本实施方式的摄像模组20以及电子装置100工作原理进行介绍。
请参阅图2至图5，由上述可知，在本申请实施方式的电子装置100中，在摄像模组20的定焦镜头23位于第一位置A时，定焦镜头23的总长最短，摄像模组20的总长也最短，这样，将摄像模组20安装在壳体10上时，不会由于定焦镜头23的镜片235数量过多也导致壳体10的厚度增加。在这样的情况下，摄像模组20基本完全容置在电子装置100的壳体10内(如图2所示)，但摄像模组20图像传感器22外对焦，摄像模组20无法正常进行拍摄工作。
在需要进行正常拍摄时，可通过驱动组件30分别驱动定焦镜头23的第一镜片组233和第二镜片组234沿光轴L向远离图像传感器22所在的一侧运动以使定焦镜头23从第一位置A运动至第二位置B(图5所示)，即，使得第二镜片组234至少部分地伸出电子装置100的壳体10(如图3所示)。从而使得摄像模组20能够在图像传感器22上对焦以实现正常的拍摄。这样，开放了定焦镜头23的总长长度，而不会由于为了实现高像素和高分辨率而增加镜头的长度而增加电子装置100的壳体10的厚度。在拍摄完成后，只需通过驱动组件30驱动第一镜片组233和第二镜片组234反向沿光轴L向图像传感器22所在的一些运动即可使得第一镜片组233和第二镜片组234均收纳在电子装置100的壳体10内。
综合上述，本申请实施方式的摄像模组20包括图像传感器22和定焦镜头23，定焦镜头23与图像传感器22对应设置，定焦镜头23包括沿定焦镜头23的光轴L间隔设置的且能够沿光轴L相对运动的第一镜片组233和第二镜片组234，第一镜片组233和第二镜片组234均能够沿光轴L向远离图像传感器22所在一侧运动以使得定焦镜头23从第一位置A运动至第二位置B，在定焦镜头23处于第一位置A时，摄像模组20在图像传感器22外对焦，在定焦镜头23处于第二位置B时，摄像模组20在图像传感器22上对焦。
此外，本申请实施方式的电子装置100包括壳体10和摄像模组20，摄像模组20安装在壳体10内，在定焦镜头23处于第一位置A时，定焦镜头23收纳在壳体10内，在定焦镜头23处于第二位置B时，定焦镜头23至少部分地伸出壳体10。
综上，在本申请实施方式的摄像模组20和电子装置100中，在定焦镜头23位于第 一位置A时，图像传感器22与定焦镜头23之间的间隔较短，整个摄像模组20的总长较短，摄像模组20在图像传感器22外对焦，摄像模组20处于非工作状态，在需要工作时，第一镜片组233和第二镜片组234相对图像传感器22运动以使定焦镜头23从第一位置A运动至第二位置B，从而使得摄像模组20在图像传感器22上对焦，进而使得摄像模组20能够正常拍摄。如此，可在摄像模组20处于第一位置A时以较短的总长封装进手机等电子装置100内，而不会增加手机等电子装置100的厚度，有利于电子装置100的轻薄化。在需要拍摄时，只需驱动第一镜片组233和第二镜片组234运动从而使得定焦镜头23伸出电子装置100的壳体10外以运动至第二位置B即可实现正常摄像功能。此外，定焦镜头23采用多个镜片组组合的方式形成，这样，每个镜片组单独封装，减少了每个镜片组需要封装的镜片235的数量，降低了镜头的组装难度，提高了镜头的组装良率。
