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，例如摄像头、人脸识别模组、环境光敏模组等，这给终端设备的装配带来极大的挑战。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，在整机尺寸确定的前提下，越来越大的屏占比会导致以往设置在终端设备的板面上的功能器件已然没有足够的安装空间。
为了增大终端设备的屏占比，相关技术中的终端设备的摄像头为伸缩式摄像头，伸缩式摄像头被设置在终端设备的壳体之内的驱动机构驱动，进而实现进出壳体。当用户需要拍摄时，控制驱动机构驱动伸缩式摄像头伸出到壳体之外，进而进行拍摄。当拍摄完成后，再控制驱动机构驱动伸缩式摄像头回缩至壳体之内，达到隐藏摄像头的目的。上述结构的终端设备能够避免摄像头对其板面空间的占用，进而能减小壳体的边框宽度，边框宽度减小则能够使得显示屏的面积增大，最终能增大终端设备的屏占比。
在相关技术中的终端设备中，驱动机构包括电机，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，才能实现对伸缩式摄像头的驱动，这无疑会导致终端设备的结构较为复杂。
当然，上述问题同样存在于闪光灯、指纹识别模组等可以伸缩的器件中。
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采用电机驱动伸缩式器件伸缩时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；
被驱动器件，所述被驱动器件设有限位部，所述被驱动器件具有回缩状态和弹出状态；
驱动机构，所述驱动机构设置在所述壳体内，所述驱动机构包括第一磁性件、限位件、线圈和弹性件，所述限位件设有作用端和限位端，所述线圈绕设于所述限位件，所述弹性件与所述被驱动器件连接；
当所述被驱动器件处于回缩状态时，所述线圈处于断电状态，所述作用端与所述第一磁性件相吸，所述限位端与所述限位部配合，所述被驱动器件位于所述壳体内；当所述被驱动器件处于弹出状态时，所述线圈处于通电状态，所述作用端与所述第一磁性件相斥，所述限位端与所述限位部分离，所述被驱动器件在所述弹性件的作用下移动至所述壳体之外；或者，
当所述被驱动器件处于回缩状态时，所述线圈处于通电状态，所述作用端与所述第一磁性件相斥，所述限位端与所述限位部配合，所述被驱动器件位于所述壳体内；当所述被驱动器件处于弹出状态时，所述线圈处于断电状态，所述作用端与所述第一磁性件相吸，所述限位端与所述限位部分离，所述被驱动器件在所述弹性件的作用下移动至所述壳体之外。
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，限位件上所设置的线圈能够使得限位件具有磁性，继而改变限位件与第一磁性件之间的作用关系。当被驱动器件处于回缩状态时，限位件与被驱动器件限位配合，使得被驱动器件即使受到弹性件的作用也不会弹出，当被驱动器件需要弹出时，限位件与被驱动器件分离，使得被驱动器件在弹性件的作用下弹出。被驱动器件结束工作后，用户按压被驱动器件，限位件重新与被驱动器件限位配合，使得被驱动器件保持在回缩状态。可见，被驱动器件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的采用电机驱动 伸缩式器件伸缩时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5所示，本公开实施例公开一种终端设备，其包括壳体100、被驱动器件200和驱动机构。
壳体100开设穿孔110，该穿孔110可以开设于壳体100的边框上，其可供被驱动器件200穿过，进而使得被驱动器件200进出壳体100。具体地， 该被驱动器件200可以包括摄像头模组、传感器、指纹识别模组、受话器、补光灯中的至少一者，当然还可以包括其他可以进出壳体100的被驱动器件。该被驱动器件200设有限位部210，此限位部210具体可以是凸起、凹槽等结构。被驱动器件200具有通过穿孔110回缩至壳体100内的回缩状态，以及通过穿孔110弹出至壳体100之外的弹出状态，被驱动器件200相对于壳体100移动时，就可以在回缩状态和弹出状态之间切换。被驱动器件200处于回缩状态时，该被驱动器件200不工作；被驱动器件200处于弹出状态时，该被驱动器件200工作。
驱动机构设置于壳体100内，其可以向被驱动器件200施加作用力，使得被驱动器件200相对于壳体100移动，该驱动机构具体可以包括第一磁性件310、限位件320、线圈330和弹性件340。第一磁性件310可以是磁铁，具体可以采用钕铁硼永磁铁。限位件320包括本体部321以及设置于该本体部321的两端的作用端322和限位端323，该作用端322与第一磁性件310相对，限位端323用于与被驱动器件200限位配合。线圈330绕设于限位件320，因此当线圈330通电时，其可以产生磁场，使得限位件320被磁化，当线圈330断电时，限位件320即失去磁性。弹性件340与被驱动器件200连接，该弹性件340可以向被驱动器件200施加弹出力，进而使被驱动器件200弹出壳体100，该弹性件340具体可以设置为弹簧。
本公开实施例中，限位件320可以可转动地设置于壳体100内，也可以可移动地设置于壳体100内。当限位件320可移动地设置于壳体100内时，作用端322远离第一磁性件310，则限位端323靠近限位部210，反之，作用端322靠近第一磁性件310，则限位端323远离限位部210。当限位件320可转动地设置于壳体100内时，作用端322远离第一磁性件310，则限位端323远离限位部210，反之，作用端322靠近第一磁性件310，则限位端323靠近限位部210。
如果限位件320可转动地设置于壳体100内，当被驱动器件200处于回缩状态时，线圈330处于断电状态，作用端322与第一磁性件310相吸，限位端323与限位部210配合，被驱动器件200位于壳体100内；当被驱动器件200处于弹出状态时，线圈330处于通电状态，作用端322与第一磁性件 310相斥，限位端323与限位部210分离，被驱动器件200在弹性件340的作用下移动至壳体100之外。
如果限位件320可移动地设置于壳体100内，当被驱动器件200处于回缩状态时，线圈330处于通电状态，作用端322与第一磁性件310相斥，限位端323与限位部210配合，被驱动器件200位于壳体100内；当被驱动器件200处于弹出状态时，线圈330处于断电状态，作用端322与第一磁性件310相吸，限位端323与限位部210分离，被驱动器件200在弹性件340的作用下移动至壳体100之外。
因此，如若用户想要使用被驱动器件200，则可以控制线圈330的通电状态，使得限位端323与限位部210分离，被驱动器件200就可以在弹性件340的作用下弹出壳体100。用户使用完被驱动器件200时，用户按压被驱动器件200，使得被驱动器件200缩回至壳体100内，此时同样可以控制线圈330的通电状态，使得限位端323与限位部210限位配合，进而限制被驱动器件200的运动，使得被驱动器件200即使受到弹性件340所施加的弹出力也不会弹出至壳体100外。可见，被驱动器件200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的采用电机驱动伸缩式器件伸缩时存在成本较高及结构较为复杂的问题。另外，该驱动机构还具有结构简单、成本低、装配简便、安全可靠、灵活性高、占用空间小等优点，进而满足终端设备的轻薄性等要求。
考虑到限位件320可转动地设置于壳体100内时，限位件320所需的运动空间相对较小，且其与壳体100内其他器件发生干涉的几率较小，因此本公开实施例可选为限位件320可转动地设置于壳体100内。此时，作用端322和限位端323分别位于限位件320的转动轴线的两侧。具体地，限位件320可以通过连接轴350可转动地设置于壳体100内，作用端322和限位端323分别位于连接轴350的两侧。
当被驱动器件200处于回缩状态时，第一磁性件310向作用端322施加磁吸力，限位端323向限位部210施加限位力。为了增大限位力，从而强化限位效果，可以使磁吸力的力臂大于限位力的力臂，也就是说，限位力大于磁吸力。
线圈330可以设置于限位件320的任意位置，只要能够磁化限位件320就可以。由于限位件320靠近被驱动器件200的部分的空间较小，因此如果将线圈330设置在该部分上，就会导致线圈330的设置空间较小，有可能无法保证所形成的磁场强度。为了解决这一问题，可以使线圈330位于第一磁性件310与限位件320的转动轴线之间。也就是说，线圈330更靠近第一磁性件310，以获得更大的安装空间。另外，当磁吸力的力臂大于限位力的力臂时，限位件320中，自转动轴线至作用端322的这一部分的长度大于自转动轴线至限位端323的这一部分的长度，因此线圈330的匝数可以适当增加，进而形成更强的磁场。
进一步的实施例中，如图1所示，驱动机构还包括设置于被驱动器件200上的第二磁性件360。限位件320的限位端323与被驱动器件200的限位部210配合时，该第二磁性件360与限位端323相吸，使得限位端323与限位部210之间所形成的限位力更大，进而强化限位效果；限位端323与限位部210分离时，第二磁性件360与限位端323相斥，使得限位端323与限位部210分离的速度更快，进而便于被驱动器件200快速弹出壳体100，以此提高被驱动器件200的弹出灵敏度。此第二磁性件360具体可以设置为钕铁硼磁石。
可选地，限位件320的作用端322具有第一弧形面322a，第一磁性件310设有第二弧形面311，当作用端322与第一磁性件310相吸时，第一弧形面322a与第二弧形面311相对。具体地，第一弧形面322a和第二弧形面311可以直接接触，也可以形成较小的间隙。该第一弧形面322a和第二弧形面311可以使作用端322和第一磁性件310相作用的部分的结构更加圆滑，使得两者不容易因彼此接触而出现划痕，两者的使用寿命有所延长。
另外，限位件320的作用端322与本体部321可以形成L形结构，以简化限位件320的结构。同时，当线圈330位于第一磁性件310与限位件320的转动轴线之间时，线圈330可以更均匀地缠绕在本体部321上，所形成的磁场也更加均匀。
本公开实施例中，第一磁性件310可能会出现漏磁的问题，为了解决该问题，驱动机构还包括设置于壳体100内的屏蔽罩370，第一磁性件310位 于该屏蔽罩370内。当然，屏蔽罩370并非将第一磁性件310完全罩住，可以在该屏蔽罩370朝向作用端322的部分上开设避让结构，使得第一磁性件310可以向作用端322施加足够的磁吸力或者磁斥力。
为了简化被驱动器件200的结构，其限位部210可选为限位槽。限位件320的限位端323位于该限位槽内时，两者限位配合，限位端323从该限位槽移出时，限位件320不再限制被驱动器件200的移动。进一步地，该限位槽具有底面211和限位面212，该底面211和限位面212均可以是平面，且两者可以相互垂直。另一种实施例中，限位面212的一端与底面211连接，限位面212的另一端沿靠近第一磁性件310的方向倾斜。此种结构便于限位件320的限位端323进出限位槽，同时可以防止限位件320与被驱动器件200在相互配合的过程中出现卡死的问题。
本公开实施例所公开的终端设备可以为智能手机、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。
