第一伸缩件300为处于压缩状态的弹性伸缩件。第一伸缩件300与摄像头200相连、且用于向摄像头200施加使其从穿孔伸出的弹力。在工作的过程中，弹力能驱动摄像头200从内腔120进入穿孔，然后从穿孔伸出壳体100之外，进而能为用户的后续拍摄做好准备。
第一伸缩件300可以为伸缩弹簧(为了区分后文的伸缩弹簧，此处的伸缩弹簧可以称之为第二伸缩弹簧)、弹性橡胶柱等具有伸缩功能的构件。具体的，壳体100之内可以设置有定位件400，定位件400用于与第一伸缩件300的一端(固定端)固定相连，第二伸缩件500的另一端为与摄像头200相连的移动端，移动端相对于固定端的移动来实现第二伸缩件500的伸缩。定位件400是壳体100内用于定位(例如固定)第一伸缩件300的一端的部件，可以是移动终端专门为第一伸缩件300配置的定位基座；也可以是移动终端内布设的其它零部件，此时该零部件除了发挥其本有的功能之外，还能起到定位第一伸缩件300一端的作用。当然，第一伸缩件300也可以通过直接与壳体100相连的方式实现其一端的定位。
控制装置600可以包括控制主体610、第一霍尔器件620和第一磁铁630。第一磁铁630设置在摄像头200上、且能随摄像头200移动。第一霍尔器件620用于感应第一磁铁630的磁通量。第一磁铁630的移动会使得第一霍尔器件620感应的磁通量发生变化。控制主体610根据第一霍尔器件620感应到的第一磁铁630的磁通量变化、控制第二伸缩件500收缩。第二伸缩件500 在处于伸展状态下可将摄像头200定位于内腔120中。第二伸缩件500的伸缩能发挥避让和定位作用。
控制主体610控制第二伸缩件500收缩，则使得第二伸缩件500与摄像头200之间的定位配合被解除，第二伸缩件500收缩后能避让摄像头200，进而使得摄像头200被第一伸缩件300从内腔120穿过穿孔后移动至壳体100之外。控制主体610可以控制第二伸缩件500伸展，则能够使得第二伸缩件500与摄像头200定位配合，进而将摄像头200定位在壳体100的内腔120中，此时，第二伸缩件500发挥定位作用。所述将摄像头200定位在内腔120中，指的是在定位配合下摄像头200不会在第一伸缩件300的弹力驱动下透过穿孔伸出到壳体100之外，由于摄像头200与第一伸缩件300之间为弹性连接，因此摄像头200能够在内腔120中通过压缩第一伸缩件300实现在设定范围内活动。
本公开实施例公开的移动终端的工作过程如下：
第二伸缩件500处于伸展状态下将摄像头200定位在壳体100的内腔120中，由于摄像头200与第一伸缩件300相连，因此按压摄像头200则能够使得第一伸缩件300进一步压缩。当用户使用摄像头200时，用户按压一下摄像头200，进而使得摄像头200带动第一磁铁630一起移动。第一磁铁630的移动会使得第一霍尔器件620感应到的第一磁铁630的磁通量变化，此种情况下，控制主体610根据第一霍尔器件620感应到的第一磁铁630的磁通量变化、控制第二伸缩件500收缩。第二伸缩件500收缩则会解除其与摄像头200的定位，进而使得摄像头200能够被第一伸缩件300的弹力驱动而进入穿孔，最后从穿孔被推出到壳体100之外。摄像头200处于壳体100之外则能够进行拍摄工作。
当用户不使用摄像头200时，用户可以直接通过按压摄像头200使其回缩至壳体100的内腔120中，最终能够在第二伸缩件500处于伸展状态时被定位在内腔120中，最终实现对摄像头200的收拢。
通过上述工作过程可知，本公开实施例公开的移动终端能够确保移动终端具备摄像功能的前提下，通过摄像头200的位置(从壳体100内移动至壳体100外，从壳体100外移动至壳体100内)转换实现其工作，摄像头200 的布设不会占用移动终端上布置显示屏的区域，也就不会限制移动终端的屏占比的进一步增大，进而能解决相关技术中摄像头的布设会影响移动终端向着大屏占比的方向发展的问题。
本公开实施例中，控制主体610既能够控制第二伸缩件500收缩，也能够控制第二伸缩件500伸展。当然，控制主体610可以仅控制第二伸缩件500的收缩，第二伸缩件500为弹性伸缩件时，则第二伸缩件500的伸展则由自身的变形恢复实现。
第一伸缩件300为弹性伸缩件，通过其自身的弹性恢复施加弹力，第一伸缩件300的形变恢复能够确保其对摄像头200驱动的稳定性。同时，第一伸缩件300仅采用一些简单的构件(例如弹簧)就能实现。这能够降低移动终端的结构复杂度，同时还能降低移动终端的制造成本。
在实际的使用过程中，第一伸缩件300推动摄像头200伸出壳体100进行拍摄的过程中，若用户不小心使得移动终端跌落，那么在摄像头200触地的过程中，第一伸缩件300则能够确保摄像头200弹性触地，进而避免摄像头200触地造成的损坏，最终能起到保护摄像头200的作用。
本公开实施例中，第二伸缩件500可以采用多种结构，例如，第二伸缩件500可以为滑块机构、液压伸缩件、气压伸缩件等。当然，第二伸缩件500可以是伸缩弹簧或者包含有伸缩弹簧的伸缩组件。本公开实施例不限制第二伸缩件500的具体结构。
请参考图3-4，一种具体的实施方式中，第二伸缩件500可以包括顶针510和第一伸缩弹簧520，顶针510与第一伸缩弹簧520相连、且随第一伸缩弹簧520的伸缩而移动。顶针510用于与摄像头200卡接定位。具体的，第一伸缩弹簧520的一端为固定端，另一端为移动端。在伸缩的过程中，移动端相对于固定端的移动能实现第一伸缩弹簧520的伸缩。顶针510与第一伸缩弹簧520的移动端相连，进而实现跟随移动。第一伸缩弹簧520的伸缩会带动顶针510移动，进而实现顶针510避让摄像头200或实现顶针510与摄像头200之间的定位配合。具体的，顶针510可以通过与摄像头200卡接定位来实现对摄像头200的定位。
在上述结构的基础上，控制主体610可以包括控制器611和第二磁铁612， 第二磁铁612可以为电磁铁。第二磁铁612与第一伸缩弹簧520的一端相连，顶针510与第一伸缩弹簧520的另一端相连。控制器611可以根据第一霍尔器件620感应到的第二磁铁612的磁通量变化、控制第二磁铁612的电流增大。第二磁铁612与顶针510磁性相吸。顶针510通常为铁质件。
在具体的工作过程中，控制器611可以增大第二磁铁612的电流，由于第二磁铁612为电磁铁，因此电流的增大会使得第二磁铁612的磁性增强，进而能够施加更大的磁吸力来吸附顶针510，顶针510被吸附会压缩第一伸缩弹簧520，进而使得两者形成的整体收缩，也就是第二伸缩件500的收缩。
当第二伸缩件500收缩后完成对摄像头200的避让时，第二伸缩件500无需一直保持在收缩状态，当然，一直保持在收缩状态需要第二磁铁612一直保持较大的电流，这也会导致移动终端的耗电增多。基于此，控制主体610还可以包括第二霍尔器件613。第二霍尔器件613用于感应第一磁铁630的磁通量变化。因此在摄像头200伸出的过程中，第一磁铁630同样会跟随摄像头200移动，第二霍尔器件613根据感应到的第一磁铁630的磁通量变化、控制第二磁铁612断电。第二磁铁612断电之后其对顶针510的吸附力消失，顶针510在第一伸缩弹簧520的变形恢复作用下重新被推出。此过程中，第一伸缩弹簧520也会相应伸展，最终实现第一伸缩件300的伸展。当然，此时第一伸缩件300处于伸展状态并没有对摄像头200进行定位。
当然，在摄像头200回缩至壳体100的内腔120时，控制器611可以重新控制第二磁铁612通电，进而通过第二磁铁612增大电流来实现对顶针510的吸附及第一伸缩弹簧520收缩，最终实现对摄像头200回缩的避让。
需要说明的是，本公开实施例中，第一磁铁630在移动的过程中本身的磁通量并未变化。通常，第一霍尔器件620和第二霍尔器件613位置确定，第一磁铁630发生移动时，则会使得第一霍尔器件620和第二霍尔器件613检测到的磁通量发生变化，控制器611则能够根据该变化进行相应的控制操作。
由于第一霍尔器件620和第二霍尔器件613感应到磁通量变化后，触发的控制操作不同。为了更方便两者进行工作，同时提高检测精度，优选的方案中，第二霍尔器件613可以设置在穿孔与第一霍尔器件620之间，即第一 霍尔器件620则可以设置在第二霍尔器件613背离穿孔的一侧。具体的，第一霍尔器件620设置在第一伸缩件300的固定端的一侧。第二霍尔器件613可以设置在边框110的内壁上。
为了简化操作，优选的方案中，顶针510可以具有倾斜面511，倾斜面511设置在顶针510朝向穿孔一侧的表面上。倾斜面511可以与摄像头200滑动配合，顶针510上与倾斜面511相背离的表面与摄像头200定位配合。上述结构的顶针510在工作的过程中，用户直接按压摄像头200，摄像头200相对于倾斜面511滑动，在滑动的过程中逐渐推动顶针510，进而使得顶针510压紧第一伸缩弹簧520收缩，进而实现对摄像头200的避让。摄像头200需要包括定位结构(例如定位凹陷)，当滑动完成之后，顶针510会在第一伸缩弹簧520的弹力作用下复位，进而使得顶针510上背离倾斜面的表面与摄像头200的定位结构定位配合，最终使得摄像头200收拢于壳体100的内腔120中。上述结构的顶针510无疑会使得摄像头200的收拢操作变得简单、方便，同时还能简化终端的结构复杂度。
为了实现对摄像头200实施更为稳定地定位，优选的方案中，第二伸缩件500可以为两个，两个第二伸缩件500对称布置在摄像头200的两侧。此种情况下，两个第二伸缩件500则能够实现对摄像头200实施更为均衡的定位。
通常情况下，摄像头200的体积较小，为了便于其安装以及与其它构件之间的装配，摄像头200可以安装在摄像头支架700上，第一伸缩件300可以通过摄像头支架700与摄像头200相连。在具体的装配过程中，摄像头200可以先安装在摄像头支架700上，然后通过摄像头支架700实现与其它构件之间的装配。优选的方案中，摄像头支架700具有容纳腔，摄像头200安装在摄像头支架700的容纳腔中。此种情况下，摄像头支架700还能对摄像头200进行防护，这能降低摄像头200被损坏的概率。为了提高摄像头支架700移动的稳定性，优选的方案中，壳体100内可以设置有轨道，摄像头支架700可以与轨道滑动配合。摄像头200通常与摄像头支架700固定相连，两者可以直接通过卡接的方式实现固定，也可以通过中间连接件(例如螺纹连接件)实现固定相连。
同样道理，第二伸缩件500可以通过与摄像头支架700之间的定为配合，来间接定位摄像头200。基于此，摄像头支架700可以包括定位部710，定位部710与第二伸缩件500定位配合。具体的，定位部710通常为摄像头支架700的边沿，如图3和图4所示。定位部710与第二伸缩件500实现定位配合的方式有多种，例如，定位部710设置有定位孔，第二伸缩件500的一端(能够移动的一端)可以通过插接的方式与定位孔定位配合，处于定位配合状态下，摄像头支架700在摄像头200的移动方向上不会发生移动。
当然，定位部710还可以借助第一伸缩件300实现对摄像头200的定位，第二伸缩件500会伸展至与定位部710相干涉的位置，第一伸缩件300的弹力会将摄像头支架700抵触在第二伸缩件500上，从而使得摄像头支架700在摄像头200的移动方向不发生移动。
为了提高装配的紧凑性以及移动终端的防尘、防水，优选的方案中，在摄像头200收拢于壳体100的内腔120后，定位部710可以与壳体100的内壁贴合，且摄像头支架700与穿孔封堵配合。此种配合方式能够避免外界的水、灰尘通过穿孔进入到移动终端的内部。
本公开实施例公开的移动终端中，移动终端可以是手机、平板电脑、可穿戴设备等具有摄像头和显示屏的设备，本公开实施例不限制移动终端的具体种类。
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。
