请参阅图1和图2，电子装置包括显示屏组件10、摄像头模组20、升降壳体30、固定壳体40和动力机构50，显示屏组件10固定在固定壳体40上用于信息显示，升降壳体30与固定壳体40可滑动连接，动力机构50用于使升降壳体30相对于固定壳体40滑动，摄像头模组20容置于升降壳体30内，从而在升降壳体30相对于固定壳体40滑动的过程中摄像头模组20可在不被固定壳体 40遮挡或者被固定壳体40遮挡的两种状态下切换。固定壳体40用于容置电池、主板、处理器、扬声器、麦克风等零件。电子装置包括智能手机、平板、笔记本、智能手表和PDA等，在此不做限定。
在非伸出状态下，摄像头模组20被固定壳体40挡住，无法接收到外界环境光，此时摄像头模组20在显示屏组件10所在平面的投影与显示屏组件10的显示区域112至少部分重叠；在伸出状态下，摄像头模组20不被固定壳体40挡住，可以正常接收到外界环境光。
请参阅图3，显示屏组件10可以包括玻璃面板11和显示屏12，显示屏12与固定壳体40连接，玻璃面板11设置在显示屏12的远离固定壳体40的一侧。玻璃面板11具有暴露显示屏12以显示信息的显示区域112，以及阻断显示屏12向外发光的非显示区域114。显示屏12用于信息显示，例如显示图像、视频或文本等信息。非显示区域114还可以用来为光线传感器、距离传感器、听筒网、点阵投影器等零部件预留安装空间。在非伸出状态下，摄像头模组20在显示屏12所在平面上的投影与显示屏组件10的显示区域112至少部分层叠设置。
在一实施例中，在非伸出状态下，摄像头模组20在显示屏12所在平面上的投影与显示屏组件10的显示区域112部分重叠设置，在伸出状态下，摄像头模组20可随升降壳体30从固定壳体40的端部滑出，从而摄像头模组20不占用显示屏组件10的非显示区域114的空间位置去获取环境光，进而显示区域112的面积扩大，非显示区域114的面积缩小。
此时，听筒、距离传感器、光线传感器、点阵投影器等零部件可以设置在非显示区域114的位置处。当然，听筒、距离传感器、光线传感器、点阵投影器等零部件中至少一个也可以设置在升降壳体30内上。
请参阅图4，在另一实施例中，在非伸出状态下，摄像头模组20在显示屏12所在平面上的投影与显示屏组件10的显示区域112完全重叠设置(如图所示)，在伸出状态下，摄像头模组20可随升降壳体30从固定壳体40的端部滑出，从而摄像头模组20不占用显示屏组件10的非显示区域114的空间位置去 获取环境光，进而显示区域112的面积进一步扩大，非显示区域114的面积进一步缩小。
其中，听筒、距离传感器、光线传感器、点阵投影器等需要占用显示屏组件10的非显示区域114的空间位置的零部件可以设置在除非显示区域114的其他位置。例如：听筒、距离传感器、光线传感器、点阵投影器等零部件中至少一个可以设置在升降壳体30内上，以使显示区域112的面积进一步扩大，非显示区域114的面积进一步缩小，从而实现显示屏组件10的显示区域112近似完全取代非显示区域114的空间位置的效果。
请参阅图5，动力机构50包括电机51、蜗杆52、减速齿轮组53和滑动件54，电机51与固定壳体40连接，电机51的输出端、蜗杆52、减速齿轮组53、滑动件54和升降壳体30依次传动连接，具体地，电机51用于通过蜗杆52带动减速齿轮组53沿滑动件54的齿轮槽541(具体请参阅图9)滚动，以使升降壳体30相对于固定壳体40滑动，从而使摄像头模组20可在不被固定壳体40遮挡或者被固定壳体40遮挡的两种状态中进行切换。
其中，电机51可以在通电状态下转动，并且可以根据电流的方向改变转动的方向，从而蜗杆52可以正向转动或者反向转动，进而可以改变蜗杆52相对于滑动件54的滑动方向，最终升降壳体30可以相对固定壳体40做远离运动或者相对固定壳体40做靠近运动。此外，电机51可以根据电流的大小来决定其转动的速度，从而与减速齿轮组53配合使升降壳体30可以以不同的速度相对固定壳体40滑动。
请同时参阅图6和图7，动力机构50还包括齿轮盒55和导向柱56，齿轮盒55与固定壳体40连接，电机51、蜗杆52和减速齿轮组53均容置于齿轮盒55的收容腔内，齿轮盒55的外侧围合形成有收纳槽551，导向柱56穿过滑动件54容置于收纳槽551内且与齿轮盒55连接，以使滑动件54能够在导向柱56的导向作用下稳定地滑行。动力机构50通过齿轮盒55和导向柱56将电机51、蜗杆52、减速齿轮组53和滑动件54连动成一个独立的整体，动力机构50可以 整体装配进入电子装置中或者整体从电子装置中取出，从而提高了电子装置拆的动力机构50的卸维修效率或者组装效率。
请同时参阅图7至图8，齿轮盒55包括盒本体552和盖板553，盖板553盖设在盒本体552上以共同围合形成收容腔，电机51、蜗杆52和减速齿轮组53均装配于收容腔内。
具体地，盒本体552包括底壁5521和侧壁5522，底壁5521开设有第一缺口5523，侧壁5522环绕底壁5521的边沿设置，侧壁5522在第一缺口5523处围设形成收纳槽551，导向柱56与侧壁5522连接，盖板553开设有第二缺口5531，盖板553盖设在侧壁5522上，第一缺口5523和第二缺口5531相互连通，盖板553、侧壁5522和底壁5521共同围合形成收容腔。
侧壁5522在收纳槽551处具有依次连接的第一侧壁5524、第二侧壁5525和第三侧壁5526，第一侧壁5524和第三侧壁5526相对设置，导向柱56的相对两端分别与第一侧壁5524和第三侧壁5526连接，第二侧壁5525设置有开口5527，开口5527可以贯穿第二侧壁5525的部分区域，滑动件54穿过开口5527与减速齿轮组53连接，此时滑动件54可以通过在滑动的过程中抵接于第二侧壁5525进行限位。具体可以理解地，在升降壳体30(请参阅图5)过度伸出或者过渡缩回至固定壳体40(请参阅图5)的过程中时，滑动件54可以通过抵接于第二侧壁5525，从而阻止升降壳体30过度拉伸固定壳体40或者撞击固定壳体40，进而保证滑动件54只在限位孔的长度距离内运行。
当然，在另一实施例中，开口5527也可以贯穿第二侧壁5525的全部区域，即第二侧壁5525完全去除掉，此时，滑动件54可以通过在滑动的过程中抵接于第一侧壁5524或者第三侧壁5526进行限位。
在其它一实施例中，减速齿轮组53穿过开口5527与滑动件54连接，此时，滑动件54可以通过在滑动的过程中抵接于第一侧壁5524和第三侧壁5526进行限位。
进一步地，动力机构50还包括缓冲件57，缓冲件57装配在收纳槽551中 且与侧壁5522连接。滑动件54与第二侧壁5525抵接限位时，缓冲件57设置在第二侧壁5525上，滑动件54与第一侧壁5524或者第三侧壁5526抵接限位时，缓冲件57设置在第一侧壁5524和第三侧壁5526上。滑动件54能够抵接于缓冲件57上，以完成对滑动件54的缓冲限位。可选地，缓冲件57可以包括弹簧、硅胶垫或者泡棉中任意一种。
请参阅图7和图9，滑动件54包括固定部542和滑动部543，固定部542的一端与升降壳体30(请参阅图5)固定连接，固定部542的相对一端与滑动部543连接，滑动部543穿过导向柱56且装配于收纳槽551内，滑动部543设置有齿轮槽541以与减速齿轮组53传动连接。滑动部543可以与收纳槽551的侧壁5522抵接或者与缓冲件57抵接，以完成对滑动部543的缓冲限位。
滑动件54的齿轮槽541的排布方向(如图9中箭头所指方向)为升降壳体30的滑动方向，导向柱56为条形柱状体，导向柱56的截面形状可以是圆形、三角形、四边形、五边形、六边形等等，导向柱56的截面形状还可以是其它形状，在此不一一赘述，滑动件54的齿轮槽541的排布方向与导向柱56的延伸方向相同。
此外，电机51的轴线与导向柱56的轴线不重合，具体指，电机51和导向柱56在同一平面或者大致在同一平面的情况下，电机51的轴线可以与导向柱56的轴线平行，电机51的轴线也可以与导向柱56的轴线呈锐角或者钝角。从而在滑动件54的齿轮槽541的排布方向上减小动力机构50的整体长度，而增大动力机构50的整体宽度，以优化动力机构50在电子装置中的布局。例如在动力机构50插入至升降壳体30的深度一定的前提下，动力机构50的整体宽度增大，从而动力机构50可以占用更多的升降壳体30的空间，从而使固定壳体40(请参阅图5)可以获得更大的容置空间，例如电池的尺寸可以做的更大，电子装置的电池容量得到了提高等等。
请参阅图7和图10，减速齿轮组53包括变向双联齿轮531和第一减速双联齿轮532。
变向双联齿轮531包括层叠同心设置的上蜗轮5311和下直齿轮5312，以保证二者的角速度相同进行同步转动。蜗杆52与上蜗轮5311传动连接以带动下直齿轮5312转动，蜗杆52与上蜗轮5311配合，从而使下直齿轮5312获得一个与电机51转动平面相互垂直的转动平面，从而达到变向的目的。
第一减速双联齿轮532包括层叠同心设置的第一减速轮5321和第二减速轮5322，以保证二者的角速度相同。下直齿轮5312与第一减速轮5321传动连接，下直齿轮5312与第一减速轮5321的线速度相同，下直齿轮5312的齿顶圆直径小于第一减速轮5321的齿顶圆直径，以使第一减速轮5321的角速度小于下直齿轮5312的角速度，从而达到传动减速的目的。第一减速轮5321带动第二减速轮5322同步转动，第二减速轮5322与滑动件54传动连接以用于驱动滑动件54滑动。
本实施例中“上”和“下”仅用于解释在某一特定姿态下(如附图7所示)下直齿轮5312和上蜗轮5311的相对位置关系，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
减速齿轮组53还包括第二减速双联齿轮533，第二减速双联齿轮533包括层叠同心设置的第三减速轮5331和第四减速轮5332，以保证二者的角速度相同。第二减速轮5322与第三减速轮5331传动连接，第二减速轮5322与第三减速轮5331的线速度相同，第二减速轮5322的齿顶圆直径小于第三减速轮5331的齿顶圆直径，以使第二减速轮5322的角速度小于第三减速轮5331的角速度，从而达到减速的目的。第三减速轮5331带动第四减速轮5332同步转动，第四减速轮5332与滑动件54传动连接以用于驱动滑动件54滑动。
可选地，第二减速轮5322与第三减速轮5331在同一面或者大致在同一面上，第一减速轮5321与第四减速轮5332在同一面或者大致在同一面上，从而保证电机51的速度在传递逐渐降低的过程中，电机51和滑动件54始终在同一面或者大致在同一面上，进而不增加动力机构50的整体厚度。
可选地，减速齿轮组53还包括连接轮554，在没有第二减速双联齿轮533 时，第二减速轮5322通过连接轮554与滑动件54传动连接以用于驱动滑动件54滑动。在有第二减速双联齿轮533时，第四减速轮5332通过连接轮554与滑动件54传动连接以用于驱动滑动件54滑动。
变向双联齿轮531、第一减速双联齿轮532、第二减速双联齿轮533、连接轮554和滑动件54的材质均为塑料。塑料可以包括聚甲醛(POM)、尼龙(PA)、聚碳酸酯(PC)、聚对苯二酞对苯二胺(PPA)、聚酯(PBT)、液晶聚合物(LCP)、聚苯硫醚(PPS)、聚醚醚酮(PEEK)等等。
请参阅图11和图12，固定壳体40包括前壳41和后壳42，后壳42盖设在前壳41上以形成用于容置升降壳体30的容置腔43，在升降壳体30滑动容置于容置腔43内时，升降壳体30的外周面分别与相应的前壳41和后壳42齐平。可选地，容置腔43贯穿前壳41的侧板，以使升降壳体30从前壳41的侧板处外露，从而使升降壳体30的容纳能力增加。
具体地，前壳41可以包括第一底板411和第一侧板412，第一侧板412与第一底板411的一侧连接且抵接于后壳42上，第一底板411、第一侧板412和后壳42共同围设形成容置腔43。显示屏组件10固定在第一底板411的远离第一侧板412的一侧上。
升降壳体30可以包括第二底板31、第二侧板32和第三底板33，第二底板31与第一底板411的位置相对应和第二侧板32与第一侧板412的位置相对应，第三底板33与第二侧板32连接且与第二底板31相对设置，第二底板31、第二侧板32和第三底板33共同围设形成安装腔34。
第一侧板412开设有第一开孔4121(请参阅图5)，第二侧板32开设有第二开孔321，第一开孔4121和第二开孔321相互连通，第一开孔4121和第二开孔321可以是四周封闭的孔状结构，第一开孔4121和第二开孔321也可以是存在开放缺口的孔状结构，孔状结构可以是圆形，孔状结构也可以方形，在此不做限定。齿轮盒55与第一底板411连接且贯穿第一开孔4121和第二开孔321，以使齿轮盒55的部分结构可以装配于升降壳体30的安装腔34内。
请继续参阅图5和图12，摄像头模组20包括前置摄像头21，前置摄像头21容置于升降壳体30内且前置摄像头21的镜头朝向第二底板31，当升降壳体30从容置腔43中滑出时，环境光能够穿过第二底板31进入前置摄像头21中。值得注意的是，此时电子装置可以进入拍照模式或者不进入拍照模式，例如升降壳体30从容置腔43中滑出时，电子装置可以激活点阵投影器进行人脸识别解锁，电子装置也可以激活光线传感器以获取环境光线信息等。
摄像头模组20还包括后置摄像头22，后置摄像头22容置于升降壳体30内且后置摄像头22的镜头朝向第三底板33，当升降壳体30从容置腔43中滑出时，环境光穿过第三底板33进入后置摄像头22中，从而避免在固定壳体40上开孔以用于使环境光照射进入固定壳体40内，进而确保固定壳体40的远离显示屏组件10的一侧的完整性。
进一步地，后壳42在对应于升降壳体30的第三底板33的位置处设置有一避让缺口421，避让缺口421用于避让升降壳体30的第三底板33，以使在升降壳体30滑动容置于容置腔43内时升降壳体30的至少部分区域能够从避让缺口421处外露。可选地，后置摄像头22可以在升降壳体30滑至容置腔43时，依然可以通过第三底板33和避让缺口421来接收环境光，从而避免频繁的伸出升降壳体30来激活后置摄像头22的正常功能。
当然，如图13所述，在另一实施例中，后置摄像头(图13上未显示)设置在前壳41和后壳42之间，后置摄像头22通过后壳42来接收环境光，从而避免频繁的伸出升降壳体30来激活后置摄像头22的正常功能。
在上述本实施中，电子装置包括摄像头模组20、升降壳体30、固定壳体40和动力机构50，摄像头模组20固定在升降壳体30内，升降壳体30与固定壳体40可滑动连接，升降壳体30可以通过动力机构50相对于固定壳体40滑动；动力机构50包括电机51、蜗杆52、减速齿轮组53和滑动件54，电机51与固定壳体40连接，电机51的输出端、蜗杆52、减速齿轮组53、滑动件54和升降壳体30依次传动连接，电机51用于通过蜗杆52带动减速齿轮组53沿滑动件 54的齿轮槽541滚动，以使升降壳体30相对于固定壳体40滑动，从而使摄像头模组20可在不被固定壳体40遮挡或者被固定壳体40遮挡的两种状态中进行切换，以实现摄像头模组20自由伸出和缩回的目的，进而避免在电子装置的固定壳体40上开设用于供摄像头模组20接收环境光的通孔。
如果消费者不需要调取摄像头模组20，升降壳体30就可以缩进电子装置的内部，此时，摄像头模组20被固定壳体40遮挡；如果消费者需要调取摄像头模组20，升降壳体30就可以从电子装置的内部伸出，摄像头模组20不被固定壳体40遮挡。这样摄像头模组20不占用显示屏组件10的非显示区域114的位置空间，进而显示屏组件10的显示区域112的面积进一步扩大，非显示区域114的面积进一步缩小，提升了电子装置整体的美观性。另外，电机51可以通过控制电流的大小，来达到给齿轮不同的转动速度的目的，进而准确地控制升降壳体30滑动的速度，以满足用户不同的拍照体验。
请参阅图5和图14，其中，电子装置包括摄像头模组20、升降壳体30、固定壳体40和动力机构50，摄像头模组20固定在升降壳体30内；动力机构50包括电机51、蜗杆52、减速齿轮组53和滑动件54，电机51与固定壳体40连接，电机51的输出端、蜗杆52、减速齿轮组53、滑动件54和升降壳体30依次传动连接。
M101：电子装置接收控制指令。
电子装置接收到的控制指令包括开始拍照指令、结束拍照指令、开始视频聊天指令、结束视频聊天指令、开始录像指令和结束录像指令等一些需要摄像头模组20配合的指令。
M102：电子装置向电机51发送执行指令。
电子装置向电机51发送执行指令，以为电机51提供电流。此时，电机51接收执行指令后带动蜗杆52转动，蜗杆52带动减速齿轮组53转动，减速齿轮组53沿滑动件54的齿轮槽541滚动，以使升降壳体30相对于固定壳体40滑动，从而使摄像头模组20可在不被固定壳体40遮挡或者被固定壳体40遮挡的 两种状态中进行切换。
当控制指令为需要调取摄像头工作的指令时，电子装置向电机51供正向电流；当控制指令为结束摄像头工作的指令时，电子装置向电机51供反向电流。正向电流指可以使电机51带动蜗杆52正向转动，以使升降壳体30可以向远离固定壳体40的方向运动，进而升降壳体30带动摄像头模组20伸出电子装置的内部而不被固定壳体40遮挡。反向电流指可以使电机51带动蜗杆52反向转动，以使升降壳体30可以向靠近固定壳体40的方向运动，进而升降壳体30带动摄像头模组20滑动至电子装置的内部而被固定壳体40遮挡。此外，电机51可以根据电流的大小来决定转动的速度，进而使升降壳体30以不同的速度运动。
以上所述仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本申请的专利保护范围内。
