摄像头组件200通常包括摄像头支架210、摄像头镜片220、摄像头230和柔性电路板240。摄像头支架210为摄像头组件200的其它组成部分提供安装基础。在本公开实施例中，摄像头支架210可以具有安装槽，摄像头镜片220固定在安装槽的槽口上，摄像头镜片220与安装槽形成安装空间，摄像头230固定在安装空间中，摄像头230可以感应透过摄像头镜片220的光线，从而实现拍摄。
安装槽的侧壁可以开设有穿孔，柔性电路板240的一端与摄像头230电连接，柔性电路板240的另一端穿过穿孔后与壳体100内的电路板电连接，电路板通常为终端设备的主板。当然，柔性电路板240还可以由其它种类的柔性电连接件代替，例如柔性线缆。柔性电路板240通过自身的形变适应摄 像头组件200的位置变化，进而维持摄像头组件200的接电。
驱动机构300设置在壳体100之内，驱动机构300与摄像头组件200相连，本公开实施例中，驱动机构300包括驱动电机310和齿条321，齿条321与摄像头组件200相连。驱动电机310与齿条321传动相连，以驱动齿条321移动。齿条321的移动，带动摄像头组件200通过开口111伸出壳体100之外或回缩到壳体100之内。
本公开实施例公开的终端设备在工作时，驱动电机310能够对齿条321移动进行驱动，齿条321沿摄像头组件200的移动方向延伸，齿条321的移动能够驱动摄像头组件200移动。当需要拍摄时，齿条321带动摄像头组件200通过开口111伸出到壳体100之外；当完成拍摄时，齿条321带动摄像头组件200通过开口111回缩到壳体100之内，进而实现摄像头组件200在壳体100内的隐藏。此种结构的终端设备能够避免摄像头组件200对设置显示屏的板面的占用，进而能够使得终端设备设置更大面积的显示屏，最终能够增大终端设备的屏幕占比。
本公开实施例公开的驱动机构300可以包括齿条组件320，齿条组件320包括齿条321和齿条支架322，齿条321可以设置在齿条支架322上，齿条支架322与摄像头组件200可以固定相连，齿条321沿摄像头组件200的移动方向延伸。驱动电机310能够驱动齿条321移动，齿条321驱动摄像头组件200通过开口111伸出壳体100之外或者回缩到壳体100之内。
为了方便传动，驱动机构300还可以包括齿轮组330，驱动电机310可以通过齿轮组330与齿条321传动连接。
如上文所述，齿条支架322与摄像头组件200固定相连，而齿条支架322为齿条321提供安装基础，驱动电机310驱动齿条321移动，能够通过驱动齿条支架322的移动，进而实现对摄像头组件200移动的驱动。具体的，齿条321可以与齿条支架322固定相连，摄像头组件200跟随齿条321实现位置的变化。
在齿条321与齿条支架322固定相连的前提下，由于齿条支架322与摄像头组件200固定相连，因此齿条321的移动距离与摄像头组件200的移动距离一致。为了实现摄像头组件200伸缩，驱动机构300在摄像头组件200 的移动方向上会占据较大的空间，这会导致终端设备的主板需要开设较大面积的挖空区域来避让，这导致在主板上集成电子器件越来越困难。
基于此，本公开实施例公开的终端设备中，齿条组件320还可以包括弹性伸缩件323，弹性伸缩件323沿摄像头组件200的移动方向伸缩，齿条321设置在摄像头组件200的一侧，而且齿条321滑动地设置在齿条支架322上，进而使得齿条321能够相对于齿条支架322发生移动，也就能够相对于摄像头组件200发生移动，由于齿条321设置在摄像头组件200的一侧，因此齿条321的移动不会受摄像头组件200的干涉。
在本公开实施例中，齿条支架322与摄像头组件200相连的端部为第一端，齿条支架322包括设置在第一端的第一限位部3221。齿条321可以开设有安装槽3211，安装槽3211沿着齿条321的长度方向延伸。安装槽3211的两端分别为开口端和封闭端，开口端与安装槽3211的槽内空间连通。开口端朝向摄像头组件200的伸出方向。
弹性伸缩件323的两端分别定位在封闭端与第一限位部3221之间，第一限位部3221随齿条321的滑动进出安装槽3211的开口端。
当用户需要拍摄时，驱动机构300开启，驱动电机310驱动齿条321向着摄像头组件200伸出的方向移动，由于齿条321可以滑动地设置在齿条支架322上，而齿条支架322与摄像头组件200固定相连，并且弹性伸缩件323的两端分别定位在安装槽3211的封闭端与第一限位部3221之间，因此齿条321相对于齿条支架322的滑动能够通过弹性伸缩件323推动第一限位部3221，第一限位部3221被推动，从而能够实现齿条支架322推动摄像头组件200向着伸出的方向移动，由于齿条321具有一定的速度而且弹性伸缩件323具有弹性，因此在齿条321移动的过程中，摄像头组件200的伸出速度会并未达到齿条321的滑动速度，弹性伸缩件323能够被逐渐压缩，当驱动电机310与齿条321的末端啮合时能够停止工作，此时弹性伸缩件323被压缩到最短，此种情况下，第一限位部3221已经从开口端相对运动到安装槽3211中。
与此同时，由于弹性伸缩件323的一端定位于安装槽3211的封闭端，而且齿条321仍然与驱动电机310处于啮合状态，在弹性伸缩件323弹性恢复 力的作用下，弹性伸缩件323会通过推动第一限位部3221，进而达到以齿条321为基础进一步推动齿条支架322移动的目的，从而能够使得摄像头组件200继续伸出。
当用户拍摄完毕后，驱动机构300开启，驱动电机310驱动齿条321向着摄像头组件200回缩的方向移动，直至齿条321复位，摄像头组件200可以被用户按压到壳体100之内，从而完成摄像头组件200的隐藏。当然，本领域技术人员可以合理地设计弹性伸缩件323的长度，能够确保摄像头组件200位于壳体100之内时，弹性伸缩件323可以处于自然状态，而不会对摄像头组件200施加弹力。
本公开实施例公开的终端设备中，驱动摄像头组件200伸出的驱动机构300在工作时，驱动电机310驱动齿条321移动，齿条321的移动能够通过弹性伸缩件323推动齿条支架322，达到推动摄像头组件200伸出的目的，同时，由于弹性伸缩件323的在齿条321移动过程中会被压缩，因此在齿条321停止后，弹性伸缩件323压缩积攒的弹性势能能够转换为继续推动摄像头组件200继续伸出的动能，整个驱动过程中驱动机构300通过弹性伸缩件323能够达到对摄像头组件200更长距离的推动，在同样的伸出距离的前提下，本公开实施例提供的终端设备的驱动机构300无疑能够在摄像头组件200的伸缩方向上占据更小的空间。
如上文所述，在摄像头组件200回缩的过程中，齿条321回位后，摄像头组件200可以被按压到壳体100内，此过程中还需要用户的额外操作，无疑不方便用户的使用。基于此，可选的方案中，齿条支架322具有第二端，齿条支架322可以包括设置在第二端的第二限位部3222，第二限位部3222可与齿条321的端部限位配合。在摄像头组件200伸出的过程中，齿条321的移动能够压缩弹性伸缩件323，在弹性伸缩件323进一步推动摄像头组件200伸出时，摄像头组件200的伸出会拉动齿条支架322继续伸出，当摄像头组件200伸出后，齿条321的端部可以与第二限位部3222接触，当驱动电机310驱动齿条321回移的过程中，齿条321可以通过与第二限位部3222的限位配合，推动第二限位部3222回移，最终能够通过第二限位部3222实现齿条支架322和摄像头组件200一起回缩，最终实现摄像头组件200通过开 口111回缩到壳体100之内。可见，该可选的方案无疑能实现摄像头组件200的自动回缩。
本公开实施例中，第一限位部3221可以是限位片，第二限位部3222也可以是限位片。本公开实施例不限制第一限位部3221与第二限位部3222的具体结构。
如上文所述，齿条支架322能够支撑齿条321，使得齿条321相对于齿条支架322运动。齿条支架322的结构可以有多种，具体的，本公开实施例公开的一种齿条支架322的结构为：齿条支架322可以包括支架主体3223，齿条321滑动地设置在支架主体3223上，第一限位部3221和第二限位部3222分别固定在支架主体3223的两端，支架主体3223同样设置在摄像头组件200的一侧，同时能够使得齿条321在摄像头组件200的一侧移动。具体的，支架主体3223可以为板状结构部，同样，本公开实施例不限制支架主体3223的具体结构。
齿条支架322不但用于安装齿条321，而且还用于实现齿条组件320与摄像头组件200之间的连接。齿条支架322可以通过多种方式实现与摄像头组件200之间的连接。在可选的方案中，齿条支架322还可以包括连接架3224，连接架3224与支架主体3223的端部相连，连接架3224向摄像头组件200所在的一侧延伸，连接架3224与摄像头组件200固定相连。具体的，连接架3224与摄像头组件200的摄像头支架210通过连接件(例如螺纹连接件)或连接结构(例如卡扣结构)固定相连。齿条支架322通过连接架3224与摄像头组件200相连，无疑能够提高连接效果。
齿条支架322可以为一体式结构，也可以为分体式结构件。在可选的方案中，齿条支架322为一体式结构，此种结构具备方便制造、简化组装等优点。
通过上文所述的工作过程可知，在摄像头组件200伸出的过程中，齿条321和齿条支架322会发生相对的运动，具体的，齿条321与齿条支架322中，一者可以设置有轨道，另一者可以设置有连接槽，连接槽与轨道之间配合，从而能够确保相对运动精度的同时，而且还能确保两者的组装。
当然，齿条321还可以通过其他结构件实现与齿条支架322之间的装配。 在可选的方案中，第一限位部3221可以开设有第一连接孔，齿条321可以开设有第二连接孔，第二限位部3222可以开设有第三连接孔，第一连接孔、第二连接孔和第三连接孔依次连通，齿条组件320还可以包括支撑杆324，支撑杆324依次穿过第一连接孔、第二连接孔和第三连接孔，支撑杆324与第一限位部3221或第二限位部3222固定相连，齿条321与支撑杆324滑动配合。当然，支撑杆324可以同时与第一限位部3221和第二限位部3222固定相连。上述方案中，支撑杆324能够起到连接齿条321与齿条支架322的作用，支撑杆324沿摄像头组件200的移动方向延伸，支撑杆324能够起到导向的作用，进而能够使得齿条321的滑动更加稳定、精确。
本公开实施例中的弹性伸缩件323的种类有多种，例如硅胶弹性件、橡胶件、螺旋弹簧，本公开实施例不限制弹性伸缩件323的具体种类。在工作的过程中，弹性伸缩件323能够伸缩变形，为了提高其变形的稳定性，可选的方案中，弹性伸缩件323可以具有中心孔，支撑杆324在装配的过程中可以穿过中心孔，从而进一步确保齿条321及摄像头组件200移动的稳定性。
安装槽3211可以开设在齿条321的多个表面上，在可选的方案中，齿条321具有齿面，安装槽3211可以开设在齿条321上与齿面相背离的表面，支架主体3223可以封堵在安装槽3211的槽口上，此种情况下，弹性伸缩件323会位于支架主体3223与齿条321形成的空间中，不但能够避免弹性伸缩件323的外露，同时还能进一步规范弹性伸缩件323的变形。
本公开实施例中，驱动电机310是驱动机构的动力源，驱动电机通常通过齿轮组330与齿条321传动相连。在可选的方案中，驱动电机可以与摄像头组件200均位于齿条321的同一侧，此种设置方式无疑能够进一步提高驱动机构300的紧凑度，进而能够进一步减小驱动机构300的占用空间。
驱动电机310和齿轮组330可以通过多种方式实现在壳体100内的安装。为了方便两者的安装，在可选的方案中，驱动机构300还可以包括安装支架340，驱动电机310和齿轮组330均可以安装在安装支架340上，安装支架340固定在壳体100内，在装配的过程中，组装人员可以先将齿轮组330和驱动电机310均组装在安装支架340上，然后再通过安装支架340在壳体100内的安装，从而实现驱动电机310和齿轮组330在壳体100内的组装，此种 结构有利于形成机构的模块化，这无疑有利于终端设备的装配，达到提高装配效率的目的。
通常情况下，驱动电机的转速较高，在驱动齿条321的过程中需要减速，基于此，齿轮组330在发挥传动连接的前提下可以发挥减速的功能。一种具体的实施方式中，齿轮组330可以包括主动齿轮331和变速齿轮332，主动齿轮331固定在驱动电机的动力输出轴上，变速齿轮332包括同轴设置的第一齿轮段3321和第二齿轮段3322，第一齿轮段3321的直径可以大于第二齿轮段3322的直径，主动齿轮331与第一齿轮段3321啮合，所述第二齿轮段3322与齿条321啮合。
在具体的驱动过程中，驱动电机带动主动齿轮331转动，主动齿轮331与第一齿轮段3321啮合，进而将动力传输给变速齿轮332，由于主动齿轮331与第一齿轮段3321啮合，两者的转动线速度相同，由于第一齿轮段3321与第二齿轮段3322同轴，因此两者的转动角速度相同，第一齿轮段3321的转动，使得第二齿轮段3322同轴转动，第二齿轮段3322与齿条321的啮合传动，从而驱动齿条321移动，由于第一齿轮段3321的直径大于第二齿轮段3322的直径，而且两者同轴转动，因此第二齿轮段3322驱动齿条321，会使得齿条321的移动速度变小，进而能够达到减速的目的。
本公开实施例公开的终端设备可以是智能手机、平板电脑、电子书阅读器、可穿戴设备(例如智能手表)、游戏机等移动终端，本公开实施例不限制终端设备的具体种类。
本公开上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本公开的实施例而已，并不用于限制本公开。对于本领域技术人员来说，本公开可以有各种更改和变化。凡在本公开的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本公开的权利要求范围之内。
