如图1-图3所示，本公开的一些实施例公开一种移动终端，其包括壳体100和摄像头模组200。
壳体100具有边框。不同结构的壳体100，形成边框的部件则不同。例如，壳体100可以包括前壳、后盖和设置在两者之间的中框。边框可以成型于中框上。此种情况下，边框作为中框的一部分。再例如，壳体100包括前盖和后盖，边框可以成型于后盖上。壳体100具有内腔，进而为移动终端的组成构件提供安装空间。通常情况下，边框开设有开口110，该开口110与内腔连通，开口110用于供摄像头模组200穿过进而进出壳体100。当然，摄像头模组200还可以通过其它通道进出壳体100，并非限于开设在边框上的开口110。
如图4-图9所示，摄像头模组200具体可以包括摄像头支架210、摄像头220以及驱动机构230。摄像头220设置于摄像头支架210上，驱动机构230设置于壳体100内，其与摄像头支架210连接，进而可以驱动摄像头支架210运动，摄像头支架210运动时可以带动摄像头220运动。具体地，当摄像头220通过开口110移动至壳体100之外时，可以实现拍摄；当摄像头220通过开口110移动至壳体100之内后，便收纳于壳体100内。此种摄像头模组200不会占据移动终端的显示区域，因此移动终端的屏占比较大。摄像头220可以设置为一个，也可以设置为两个甚至更多个。
为了实现摄像头220相对于壳体100的运动，上述驱动机构可以包括驱动源231和驱动轴232，驱动源231具体可以是驱动电机，驱动轴232与该驱动源231相连接，使得驱动源231可以驱动驱动轴232转动。摄像头支架210和驱动轴232中，一者设有第一定位结构，另一者设有第二定位结构。壳体100上可以设置限位滑轨，该限位滑轨可以保证摄像头支架210或者摄像头220对准开口110，以防摄像头支架210或者摄像头220运动时与壳体100干涉。同时，该限位滑轨还可以在摄像头220相对于壳体100尚未伸出到位时，限制摄像头支架210相对于壳体100的转动，使得摄像头支架210可以在驱动轴232的驱动下相对于壳体100移动。
当摄像头支架210移动时，第一定位结构与第二定位结构分离，此时驱动轴232可以通过摄像头支架210带动摄像头沿驱动轴232的轴线方向移动，使得摄像头220可以从开口110伸出至壳体100之外，或者从开口110缩回至壳体100内；当摄像头220伸出至壳体100之外时，摄像头支架210移动至第一定位结构与第二定位结构定位配合的位置，驱动轴232驱动摄像头支架210绕前文所述的轴线转动。当摄像头支架210转动时，摄像头220随之转动，即驱动轴232可以通过摄像头支架210带动摄像头220绕前述轴线转动，摄像头220朝向将会发生变化，进而可以实现不同方向上的拍摄。
具体地，当摄像头220需要实施拍摄操作时，驱动机构230首先驱动摄像头支架210移动，摄像头支架210带动摄像头220移动，使得摄像头220伸出壳体100，这个过程中第一定位结构和第二定位结构逐渐靠近。当摄像头220伸出到位后，如果摄像头220的拍摄方向为摄像头220在当前状态下所朝向的方向，那么摄像头220拍摄完毕后即可在驱动机构230的驱动作用下缩回至壳体100内，这个过程中第一定位结构和第二定位结构分离并逐渐远离；如果摄像头220的拍摄方向不是摄像头220在当前状态下所朝向的方向，那么驱动机构230可以向摄像头支架210施加作用力，使得摄像头220旋转并最终到达目标位置，拍摄完毕后，摄像头220可以在驱动机构230的作用下复位，并缩回壳体100内，这个过程中第一定位结构和第二定位结构同样相互分离并逐渐远离。
需要说明的是，摄像头220伸出壳体100之外以及缩回壳体100内的过程中，驱动轴232的转动方向相反。
由上述内容可知，本公开的一些实施例公开的摄像头模组200既可以实现前摄，又可以实现后摄。故，移动终端可以仅设置一个摄像头模组200，无需同时设置前置摄像头和后置摄像头，因此移动终端内可供其他零部件安装的空间更大，进而使得移动终端的结构设计更加简单。同时，移动终端的厚度将会随之减小，其成本随之降低。
另外，上述摄像头模组200还具有以下优点：
驱动机构230可以带动摄像头220进行任意角度(例如90°、180°、360°等)的旋转，因此摄像头模组200可以实现全景拍摄等拍摄模式，使得摄像头 模组200的拍摄模式更多样化，用户体验更好；当摄像头模组200缩回壳体100内时，其与移动终端的天线结构之间的距离增加，一方面使得摄像头模组200不再占用天线结构的净空空间，另一方面使得摄像头模组200工作时对天线结构产生的射频干扰更弱，最终提升天线结构的性能；通过旋转的方式切换拍摄模式时，不会出现黑屏等卡顿现象，使得用户体验更好。
为了简化摄像头模组200的结构，摄像头支架210和驱动轴232中，一者设有内螺纹，另一者设有外螺纹，该内螺纹与外螺纹配合。当驱动轴232在驱动源231的作用下转动，且第一定位结构与第二定位结构分离时，驱动轴232通过这里的外螺纹和内螺纹驱动摄像头支架210沿驱动轴232的轴线方向移动，使得摄像头220在摄像头支架210的作用下伸出至壳体100之外。当摄像头220伸出到位后，第一定位结构与第二定位结构定位配合，驱动轴232驱动摄像头支架210转动，摄像头支架210带动摄像头220转动，从而改变摄像头220的朝向。
一种可选的实施例中，为了简化摄像头模组200的结构，摄像头支架210可以包括螺管211，其中：该螺管211设有前文所述的内螺纹，驱动轴232套装于该螺管211内，且驱动轴232设有前文所述的外螺纹；或者，螺管211设有前文所述的外螺纹，螺管211套装于驱动轴232内，且驱动轴232设有前文所述的内螺纹。进一步地，第一定位结构包括设置于螺管211上的定位销240，第二定位结构包括设置于驱动轴232上的定位孔232a。当定位销240插入定位孔232a时，驱动轴232与螺管211连接成一体，使得驱动轴232可以转动带动驱动摄像头支架210转动，进而实现摄像头220相对于壳体100的转动；当定位销240与定位孔232a分离时，驱动轴232可以驱动摄像头支架210移动，进而实现摄像头220相对于壳体100的移动。此种定位销240和定位孔232a的结构形式，可以简化第一定位结构和第二定位结构，使得摄像头模组200的结构更加简单。
具体地，可以在上述定位销240上设置导向面，使得定位销240随着摄像头支架210的移动可以插入定位孔232a内，也可以从定位孔232a中移出，但是此种方式的可靠性较差，导致摄像头220相对于壳体100的运动不够顺畅。为了解决这一问题，第一定位结构还包括设置于螺管211上的磁性驱动部250， 该磁性驱动部250驱动定位销240插入定位孔232a或者与定位孔232a分离。也就是说，磁性驱动部250可以与定位销240磁性作用，继而向定位销240施加磁吸力或者磁斥力，使得定位销240可以相对于螺管211移动。
进一步的实施例中，上述磁性驱动部250可以包括安装部以及缠绕在该安装部上的线圈，定位销240设置于安装部上，且定位销240的至少一部分位于线圈内。当线圈通电或者断电时，其向定位销240施加的作用力的方向不同，进而实现定位销240相对于螺管211运动的目的。由于安装部和线圈所占用的空间较小，因此此种磁性驱动部250占用的空间更小，更便于移动终端内其他零部件的布置。并且，此种磁性驱动部250的控制精度更高。
为了提升定位销240与定位孔232a的配合效果，可以使定位销240的延伸方向垂直于驱动轴232的轴线方向，并使定位孔232a沿驱动轴232的径向延伸。当定位销240与定位孔232a相互配合时，两者之间形成的作用力几乎都是有效的作用力，使得定位销240和定位孔232a之间的作用力更大，两者不容易因意外情况而相互脱离。因此，该结构可以提升螺管211与驱动轴232同步转动时的可靠性。
上述定位销240的数量可以是一个、两个甚至更多个，为了增加螺管211与驱动轴232之间的连接点数量，从而提升螺管211与驱动轴232同步转动时的可靠性和稳定性，可以将定位销240的数量设置为至少两个。这些定位销240中包括第一定位销和第二定位销，该第一定位销和第二定位销沿驱动轴232的径向分布在驱动轴232的两侧，使得定位销240的数量尽量少，且能够提升螺管211与驱动轴232同步转动时的可靠性和稳定性。
当定位销240设置为至少两个时，定位孔232a可以对应设置为至少两个，各定位销240可以与各定位孔232a一一对应地配合。但是，为了简化驱动轴232的结构和加工工艺，可以将定位孔232a设置为贯穿驱动轴232的通孔，第一定位销和第二定位销可分别插入该定位孔232a的两端。需要说明的是，定位销240在螺管211上的设置位置以及定位孔232a在驱动轴232上的设置位置可以通过摄像头220的移动距离以及旋转角度等确定，使得移动终端可以根据摄像头220的移动距离以及旋转角度控制定位销240与定位孔232a的配合状态。
一种可选的实施例中，定位销240可以设置于螺管211远离摄像头220的一端。如此设置一方面可以保证定位销240所处的位置满足摄像头220的移动距离的要求，同时可以尽量缩短螺管211的长度，使得螺管211占用的空间更小。
由于第一定位结构或者第二定位结构可能会相对于螺管211或者驱动轴232凸出，因此为了提升摄像头支架210转动时的顺畅性，可以在壳体100上开设避让槽，当摄像头220伸出至壳体100之外时，第一定位结构或者第二定位结构在该避让槽内转动，因此该避让槽可以防止第一定位结构或者第二定位结构与壳体100干涉，从而达到前述目的。
本公开的一些实施例所公开的移动终端可以为智能手机、平板电脑、电子书阅读器或可穿戴设备。当然，该移动终端也可以是其他设备，本公开的一些实施例对此不做限制。
本公开的一些实施例还公开一种移动终端的控制方法，该控制方法可以应用于第一定位结构包括定位销240和磁性驱动部250，第二定位结构包括定位孔232a的移动终端，其具体可以包括：
S110、检测定位销240与定位孔232a的相对位置；
由于驱动轴232通过摄像头支架210带动摄像头220移动时，定位销240与定位孔232a相对靠近，因此两者的相对位置将发生变化，检测该相对位置可以获知摄像头220相对于壳体100所处的位置。
S120、当定位销240相对于定位孔232a到达预设位置时，控制磁性驱动部250驱动定位销240插入定位孔232a，以使驱动机构230通过摄像头支架210驱动摄像头220转动；
当定位销240相对于定位孔232a到达预设位置时，即表示摄像头220已经伸出到位，此时定位销240与定位孔232a正对，磁性驱动部250向定位销240施加作用力后，定位销240就可以插入定位孔232a，从而使得驱动轴232可以与螺管211同步转动，从而带动摄像头220转动。
S130、当摄像头220的转动角度等于预设角度时，控制磁性驱动部250驱动定位销240与定位孔232a分离。
这里的预设角度可以是摄像头220拍摄完毕后所处的角度，也可以是摄像 头220复位后所处的角度，在该预设角度下，摄像头220已经结束拍摄工作，并且需要缩回壳体100内。此时，磁性驱动部250向定位销240施加反向作用力，使得定位销240与定位孔232a分离，驱动轴232可以带动螺管211移动，从而带动摄像头220移动并缩回壳体100内。
上述控制方法可以通过磁性驱动部250精确地控制定位销240与定位孔232a的配合状态，从而实现驱动轴232带动摄像头220移动及转动的目的。
基于上述控制方法，本公开的一些实施例还公开一种移动终端，该移动终端包括上文所述的摄像头模组(该摄像头模组中，第一定位结构包括定位销240和磁性驱动部250，第二定位结构包括定位孔232a)，其还包括：
检测模块，用于检测定位销240与定位孔232a的相对位置；
控制模块，用于在定位销240相对于定位孔232a到达预设位置时，控制磁性驱动部250驱动定位销240插入定位孔232a，以使驱动机构230通过摄像头支架210驱动摄像头220转动，并在摄像头220的转动角度等于预设角度时，控制磁性驱动部250驱动定位销240与定位孔232a分离。
这里的检测模块和控制模块可以通过磁性驱动部250精确地控制定位销240与定位孔232a的配合状态，从而实现驱动轴232带动摄像头220移动及转动的目的。
