本公开涉及一种终端设备。
随着终端设备(例如手机、平板电脑)的功能越来越多，终端设备上配置的功能器件越来越多，而且，随着用户对终端设备外观需求的提升，用户越来越青睐大屏占比的终端设备。
为了增大终端设备的屏占比，相关技术中的终端设备采用电机驱动伸缩模组运动，从而使伸缩模组可以相对于终端设备的壳体伸出和缩回。此种伸缩模组对显示区域的占用较少，因此终端设备的屏占比比较高。
但是，电机会导致终端设备的成本较高，而且采用电机驱动需要配置较为复杂的传动机构，才能实现对伸缩模组的驱动，这无疑会导致终端设备的结构较为复杂。
发明内容
本公开公开一种终端设备，以解决相关技术中的终端设备中伸缩模组的驱动方式存在成本较高以及结构较为复杂的问题。
为了解决上述问题，本公开采用下述技术方案：
一种终端设备，包括：
壳体；
伸缩模组，所述伸缩模组可移动地设置于所述壳体；
弹性驱动件，所述弹性驱动件设置于所述壳体内，且所述弹性驱动件驱动所述伸缩模组伸出所述壳体；
限位组件，所述限位组件设置于所述壳体内，所述限位组件包括限位部和用于驱动所述限位部的磁性驱动部，所述限位部在限位位置和释放位置之间可转动，在所述限位位置，所述限位部与所述伸缩模组配合以限制所述伸缩模组移动，在所述释放位置，所述限位部释放所述伸缩模组以允许所述伸缩模组移动。
本公开采用的技术方案能够达到以下有益效果：
本公开公开的终端设备中，当伸缩模组缩回壳体内时，限位部处于限位位置，此时限位部与伸缩模组配合以限制伸缩模组移动。当伸缩模组需要伸出壳体时，磁性驱动部可以驱动限位部，使得限位部释放伸缩模组以允许伸缩模组移动，弹性驱动件就可以驱动伸缩模组伸出壳体。伸缩模组使用完毕后，用户按压伸缩模组，伸缩模组向壳体内移动，限位部可以从释放位置向限位位置移动，进而使限位部与伸缩模组配合以限制伸缩模组移动，使得伸缩模组保持在缩回壳体内的状态。可见，伸缩模组的伸缩移动无需电机以及结构较为复杂的传动机构，因此，本公开实施例公开的终端设备能解决相关技术中采用电机驱动伸缩模组伸缩存在成本较高及结构较为复杂的问题。

为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开具体实施例及相应的附图对本公开技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
以下结合附图，详细说明本公开各个实施例公开的技术方案。
如图1-图3所示，本公开实施例公开一种终端设备，其包括壳体(图中未示出)、伸缩模组100、弹性驱动件210和限位组件。
壳体开设开口，具体地，壳体具有边框，该开口可以开设于边框的顶部。此开口可供伸缩模组100进出壳体，进而实现伸缩模组100的伸出和缩回。
伸缩模组100可移动地设置于壳体，进而通过开口进出壳体。该伸缩模组100相对于壳体伸出时，可以实现对应的功能；伸缩模组100相对于壳体缩回时，便收纳于壳体内。此种伸缩模组100不会占据终端设备的显示区域，因此终端设备的屏占比较大。本公开实施例中，伸缩模组100可以包括摄像头、传感器、指纹识别模组、受话器、补光灯中的至少一者。
弹性驱动件210具备弹性，其设置于壳体内。该弹性驱动件210可以与伸缩模组100抵靠或者连接在一起，当伸缩模组100受压而缩回壳体内时，伸缩模组100按压或者拉伸弹性驱动件210，使得弹性驱动件210发生变形，弹性驱动件210可以向伸缩模组100施加反作用力，即弹出力，在该弹出力的作用下，弹性驱动件210可以驱动伸缩模组100伸出壳体。为了提供更稳定的弹出力，弹性驱动件210可以设置为弹簧，终端设备还可以包括与伸缩模组100连接的导向杆260，弹性驱动件210套在该导向杆260的外部，其一端与导向杆260连接或者抵靠，另一端与伸缩模组100连接或者抵靠。
限位组件设置于壳体内，其可以包括限位部220和磁性驱动部230。限位部220转动设置于壳体内，因此其可以在限位位置和释放位置之间可转动，磁性驱动部230可以驱动限位部220。当伸缩模组100需要保持缩回状态时，限位部220处于限位位置，此时限位部220与伸缩模组100配合，从而可以向伸缩模组100施加作用力，以克服弹性驱动件210施加于伸缩模组100的 弹出力，达到限制伸缩模组100移动的目的，使得伸缩模组100无法弹出。当伸缩模组100需要伸出壳体时，限位部220处于释放位置，此时限位部220可以与伸缩模组100分离而撤去限位部220对于伸缩模组100的限位作用，从而释放伸缩模组以允许伸缩模组100移动，使得伸缩模组100可以弹出。
磁性驱动部230具体可以是电磁结构，其通电与断电时的磁性状态不同，进而可以通过磁性作用驱动限位部220转动。具体地，磁性驱动部230可以仅驱动限位部220从限位位置转动至释放位置，也可以仅驱动限位部220从释放位置转动至限位位置，还可以同时实现限位部220从限位位置转动至释放位置、从释放位置转动至限位位置。该磁性驱动部230可以与限位部220相连，也可以保持一定的距离，只要能够向限位部220施加磁力即可。
由上可知，当伸缩模组100处于缩回状态时，限位部220处于限位位置，此时伸缩模组100与限位部220限位配合，弹性驱动件210因变形向伸缩模组100施加弹出力，但由于限位部220的限制，该弹出力不会发挥作用，伸缩模组100无法移动。如果伸缩模组100需要工作，磁性驱动部230向限位部220施加驱动力，使得限位部220沿远离伸缩模组100的方向运动，进而与伸缩模组100分离，最终到达释放位置。此时限位部220对于伸缩模组100的限制消失，弹性驱动件210向伸缩模组100施加的弹出力将会发挥作用，使得伸缩模组100移动至壳体之外。
伸缩模组100使用完毕之后，用户可以按压伸缩模组100，伸缩模组100受到用户施加的按压力而移动至壳体内，限位部220可以在磁性驱动部230的作用下从释放位置向限位位置移动，即限位部220靠近伸缩模组100并与伸缩模组100限位配合，此时伸缩模组100重新回到前文所述的缩回状态。如此往复，就可以通过伸缩模组100移动而使伸缩模组100在工作状态和非工作状态之间切换，伸缩模组100不占用显示区域的面积，进而提高终端设备的屏占比。
本公开实施例中，伸缩模组100的伸缩移动无需电机以及结构较为复杂的传动机构，因此，本公开实施例公开的终端设备能解决相关技术中采用电机驱动伸缩模组100伸缩存在成本较高及结构较为复杂的问题。
如果磁性驱动部230同时实现限位部220从限位位置转动至释放位置、 从释放位置转动至限位位置，那么终端设备的能耗就会偏高。因此，限位组件还包括弹性复位件240，该弹性复位件240设置于壳体内，且弹性复位件240与限位部220相连，弹性复位件240可以驱动限位部220向释放位置转动。伸缩模组100需要伸出时，磁性驱动部230不再向限位部220施加作用力，使得限位部220在弹性复位件240的作用下沿远离伸缩模组100的方向运动，进而与伸缩模组100分离，最终到达释放位置。伸缩模组100使用完毕之后，用户可以按压伸缩模组100，伸缩模组100受到用户施加的按压力而移动至壳体内，限位部220在磁性驱动部230的作用下从释放位置向限位位置移动，从而限制伸缩模组100移动。此状态下，弹性复位件240变形，从而为限位部220的下一次运动做准备。
为了提供更稳定的复位力，可以将弹性复位件240设置为弹簧。
限位部220具体可以包括转动基体221以及分别设置于转动基体221的相对两侧的第一端部222和第二端部223。这里的第一端部222与弹性复位件240连接，第二端部223与磁性驱动部230连接。采用此种结构后，限位部220基本呈条形，其结构比较简单，且占用的空间更小，便于伸缩模组100、限位部220、磁性驱动部230和弹性复位件240的布置。
如前所述，限位部220的运动可以通过磁性驱动部230和弹性复位件240共同控制，当伸缩模组100缩回时，磁性驱动部230可以通电或者断电，使得限位部220在伸缩模组100缩回到位后与伸缩模组100限位配合。磁性驱动部230的通电或者断电时机可以通过程序控制，但是为了更快速地响应伸缩模组100的缩回，在伸缩模组100缩回壳体的过程中，伸缩模组100将与第二端部223接触，进而带动限位部220转动，以使第一端部222从释放位置向限位位置运动，即第一端部222靠近伸缩模组100，并最终与伸缩模组100限位配合。另外，当第一端部222与弹性复位件240连接，第二端部223与磁性驱动部230连接时，伸缩模组100驱动第二端部223转动到一定程度后，磁性驱动部230工作并使得第一端部222的位置得以保持，使得第一端部222可靠地与伸缩模组100限位配合，此时整个结构的控制都会比较简单。
上述第二端部223可以与转动基体221平齐，两者形成直杆状结构。但是，如果采用这种结构，伸缩模组100与第二端部223之间的接触面积会比 较小，不利于作用力的传递，并且也很容易在伸缩模组100和第二端部223的表面形成划痕，对于伸缩模组100的精确伸缩产生负面影响。为了解决这一问题，第二端部223可以在转动基体221的径向方向上向外且向伸缩模组100凸出。此时可以适当调整第二端部223的表面结构，使得第二端部223与伸缩模组100之间的接触面积有所增大，继而解决前述问题。
如前所述，对于相互接触以传递作用力的部件来说，彼此接触时的面积大小将会影响作用力的传递效果和结构的完整性。基于此，本公开实施例中，可以在伸缩模组100上设置弧形施力面110，在第二端部223上设置弧形受力面223a，该弧形施力面110与弧形受力面223a适配，以使第二端部223和伸缩模组100相对可滑动，两者可以保持较大的接触面积，以此提升作用力传递的效果，同时保证结构的完整性。
需要说明的是，上述的弧形施力面110及弧形受力面223a均是从主动施加作用力的角度进行命名，实际使用时，受力面也可能施力，施力面也可能受力，本文对此不做限制。
为了便于伸缩模组100与限位部220限位配合，可以在伸缩模组100上开设卡槽120，第一端部222的朝向伸缩模组100的一侧具有卡勾222a，在限位位置，卡勾222a卡接在卡槽120内以限制伸缩模组100移动。
进一步地，上述卡槽120具有第一限位平面121，卡勾222a可以与该第一限位平面121配合，且第一限位平面121垂直于伸缩模组100的移动方向(即开口的贯穿方向)。此种结构下，第一限位平面121与卡勾222a之间的作用力可以最大程度地形成限制伸缩模组100的作用力，使得伸缩模组100更加可靠地保持在缩回状态。
一种具体实施例中，限位部220的第二端部223可以与磁性驱动部230连接。为了便于连接两者，可以设置连接件250，该连接件250的一端与第二端部223铰接，该连接件250的另一端与磁性驱动部230铰接，使得第二端部223与磁性驱动部230通过该连接件250相连。
当限位部220的第二端部223与磁性驱动部230连接时，其第一端部222与弹性复位件240连接。为了实现第一端部222与弹性复位件240之间的可靠连接，限位部220的第一端部222设有连接柱224，弹性复位件240的一 端与壳体连接，另一端与连接柱224连接。为了防止弹性复位件240与第一端部222出现干涉，可以将连接柱224设置于第一端部222背离伸缩模组100的一侧。
可选地，弹性驱动件210位于伸缩模组100的一侧，限位组件和弹性复位件240均位于伸缩模组100的另一侧。如此设置后，弹性驱动件210的变形和复位基本不会受到限位部220、磁性驱动部230和弹性复位件240的影响，同时限位部220、磁性驱动部230和弹性复位件240之间的相互作用关系也不会受到弹性驱动件210的影响。并且，限位部220、磁性驱动部230和弹性复位件240之间的相互作用比较密集，将三者设置到一起可以缩短动力的传递路径，以便于伸缩模组100快速响应用户的拍摄需求，以及快速回复至缩回状态。
本公开实施例所公开的终端设备可以为智能手机、笔记本电脑、平板电脑、电子书阅读器或可穿戴设备。当然，该终端设备也可以是其他设备，本公开实施例对此不做限制。
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。
