本发明要求在2020年03月30日提交中国专利局、申请号为202010241344.7、发明名称为“电子设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本发明涉及通信技术领域，尤其涉及一种电子设备。
背景技术
随着电子设备(例如手机、平板电脑)的功能越来越多，电子设备上配置的功能器件越来越多，这给电子设备的装配带来极大的挑战。随着用户对电子设备外观需求的提升，用户越来越青睐大屏占比的电子设备。
以摄像头为例，为了增大电子设备的屏占比，目前的电子设备的摄像头为升降式摄像头，该升降式摄像头被设置在电子设备的壳体之内的驱动机构驱动，进而进出壳体。当用户需要拍摄时，控制驱动机构驱动升降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升降式摄像头回缩至壳体之内，达到隐藏摄像头的目的。此电子设备能够避免摄像头对其板面空间的占用，从而增大电子设备的屏占比。
在目前的电子设备中，需要在电子设备中做伸缩运动的功能组件均需要驱动机构进行驱动。而驱动机构包括电机，该电机需要配置较为复杂的传动机构，该传动机构通常包括丝母导杆、弹簧导杆等结构，用于在驱动功能组件移动的过程中起到导向的作用，以限定功能组件在电子设备内部的运行方向。然而这些器件均需要占用电子设备内的空间，因此导致驱动组件在电子设备中的占用较大的内部空间。
发明内容
本发明公开一种电子设备，以解决电子设备的驱动机构占用的空间较大这一问题。
为了解决上述问题，本发明采用下述技术方案：
一种电子设备，包括：壳体，所述壳体设有开口；功能模组，所述功能模组可通过所述开口回缩至所述壳体之内或伸出至所述壳体之外；驱动机构，所述驱动机构设置于所述壳体内，所述驱动机构包括驱动源、丝杠、丝母套组和卡钳，所述驱动源与所述丝杠驱动相连，所述丝母套组包括配合部，所述配合部与所述丝杠螺纹配合，所述卡钳的第一端与所述配合部限位配合，所述卡钳的第二端与所述功能模组固定连接；其中，所述配合部的横截面形状为多边形。
本发明采用的技术方案能够达到以下有益效果：
本发明公开的电子设备中，驱动机构包括驱动源、丝杠、丝母套组和卡钳，卡钳的第一端与配合部限位配合，且配合部的横截面形状为多边形，因此配合部的转动将被卡钳限制，从而使得配合部可以带动卡钳仅沿着丝杠移动，而无法随丝杠一起转动，因此该结构 可以通过卡钳与配合部之间的配合同时实现驱动力的传递以及限制配合部转动的目的，该电子设备可以省去用于导向的额外结构，使得驱动机构所占用的空间更小。

如图1至图5所示，本发明实施例公开一种电子设备，其包括壳体100、功能模组200和驱动机构。
壳体100可以作为电子设备的主体结构，其可以为电子设备的其它零部件提供安装基础，该壳体100设有开口110，此开口110可供功能模组200进出壳体100。可选地，壳体100可以包括边框，开口110可以设置于边框。
功能模组200可通过开口110回缩至壳体100之内或伸出至壳体100之外。可选地，功能模组200可以包括支架210以及设置于该支架210上的功能器件。当功能模组200通过开口回缩至壳体100之内时，功能模组200可以处于非工作状态，此时功能模组200隐藏于壳体100之内。当功能模组200通过开口110伸出至壳体100之外时，功能模组200可以处于工作状态，当功能模组200工作完毕时，则可以通过开口回缩至壳体100之内。此种功能模组200可以不占用电子设备的显示区域，因此可以提升电子设备的屏占比；同时，壳体100不需要对应功能模组200设置安装孔等结构，使得电子设备的外观一致性更好，用户体验更佳。可选地，功能模组200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，当然，功能模组200也可以包括其它器件，本发明实施例对此不作限制。
驱动机构设置于壳体100内，驱动机构包括驱动源310、丝杠320、丝母套组和卡钳 370，驱动源310与丝杠320驱动相连，丝母套组包括配合部330，配合部330与丝杠320螺纹配合，卡钳370的第一端与配合部330限位配合，卡钳370的第二端与功能模组200固定连接。其中，配合部330的横截面形状为多边形，相对应地，卡钳370的第一端的横截面形状也可以为多边形，且两者形状配合，此时，卡钳370可以限制配合部330的转动，从而使得卡钳370的第一端与配合部330更可靠地限位配合。这里的卡钳370可以采用卡配的方式与配合部330配合，从而实现作用力的传递。卡钳370和功能模组200的支架210分体设置，或者，两者也可以一体成型，相对而言，当卡钳370和功能模组200的支架210一体成型时，作用力可以更加高效地传递。
可选地，上述驱动源310可以采用驱动马达，也可以采用压电件等能够输出驱动力的结构，只要该驱动源310能够输出驱动力以驱动丝杠320转动即可，因此本发明实施例不限制驱动源310的具体形式。驱动源310可以设置在开口110和配合部330之间，从而使得驱动机构的结构更加紧凑。另外，配合部330的横截面形状可以为三角形、矩形、五边形、六边形，八边形等，对应地，卡钳370的第一端的横截面形状可以为三角形、矩形、五边形、六边形，八边形等。本领域技术人员可以理解的是，卡钳的形状可与配合部330的形状相匹配，即配合部330的形状为四边形，卡钳370的形状也为四边形。在另一些实施例中，卡钳370的形状也可以与配合部330不同，但应保证在配合部330具有棱边的位置，能与卡钳370相对应的棱边配合，且需要在两个棱边之间增大摩擦力，以防止两者脱离。本发明实施例对配合部330的横截面形状以及卡钳370的第一端的横截面形状不作限制。需要说明的是，这里的横截面平行于电子设备的厚度方向，同时垂直于功能模组200的移动方向。
采用上述方案时，驱动源310可以驱动丝杠320转动，由于丝杠320与配合部330螺纹配合，同时卡钳370可以限制配合部330的转动，因此在丝杠320的带动下，配合部330可以沿着丝杠320移动，而配合部330可以通过卡钳370将作用力传递至功能模组200，因此功能模组200可以在驱动机构的作用下相对于壳体100移动，进而在不同的状态之间切换。
本发明实施例中，配合部330的横截面形状为多边形，因此配合部330的转动将被卡钳370限制，从而使得配合部330可以带动卡钳370仅沿着丝杠320的延伸方向移动，而无法随丝杠320一起转动，因此该结构可以通过卡钳370与配合部330之间的配合同时实现驱动力的传递以及限制配合部330转动的目的，该电子设备可以省去用于导向的特定装置，使得驱动机构所占用的空间更小。同时，该驱动机构的重量有所降低，从而减小电子设备的重量，更有利于电子设备的轻薄化设计。
进一步的实施例中，上述丝母套组还包括弹性件350和活动挡板360，活动挡板360通过弹性件350与配合部330相连接，活动挡板360位于配合部330的远离开口110的一侧，卡钳370可相对于配合部330滑动，且卡钳370沿丝杠320移动。在卡钳370与配合部330至少部分分离的情况下，弹性件350带动活动挡板360，使卡钳370与配合部330接触。首先，卡钳370在限制配合部330的转动的同时，可以相对于配合部330滑动，使得两者的配合处可以产生一定的活动余量，当功能模组200需要伸出至壳体100之外时，丝杠320带动配合部330移动，配合部330带动活动挡板360移动，当卡钳370与活动挡板360相接触时，活动挡板360可以带动卡钳370移动，从而带动功能模组200移动。其 次，如果功能模组200受到外力作用，该外力将通过卡钳370传递至活动挡板360，活动挡板360相对于配合部330移动，此时弹性件350可以发生变形，从而减小配合部330的移动量，甚至使得配合部330不发生移动，从而防止功能模组200受到的外力对驱动机构造成损害。
可选地，上述的弹性件350可以是弹簧，或者其他具有弹性的部件。
当功能模组200受到外力作用时，卡钳370将与活动挡板360接触并带动活动挡板360移动，如果功能模组200受到的外力较大，那么卡钳370的移动幅度较大，导致卡钳370容易与配合部330脱离，致使卡钳370与配合部330之间的作用力传递路径被切断。因此，为了防止此种情况出现，一种可选的实施例中，电子设备还可以包括检测件和控制件，其中，检测件设置于壳体100内，在卡钳370与配合部330至少部分分离的情况下，检测件被触发，并用于检测卡钳与配合部之间的相对距离。相对距离可以是卡钳的重心与配合部的重心之间的距离，也可以是卡钳的第一表面和配合部的第二表面之间间隔的距离，其中卡钳的第一表面和配合部的第二表面在卡钳和配合部未分离的情况下，两个表面共面。控制件设置于壳体100内，且控制件分别与检测件和驱动源310电连接，在检测件被触发的情况下，控制件根据检测件的检测结果控制驱动源310，使得驱动源310处于工作状态。此实施例中，一旦卡钳370与配合部330出现至少部分分离的情况，检测件即可被触发而发送相关信号，控制件可以根据该信号控制驱动源310处于工作状态，使得配合部330移动，从而使得配合部330可以与卡钳370可靠地配合。进一步地，控制件控制驱动源310处于工作状态后，驱动源310可以通过卡钳370带动功能模组200回缩至壳体100内，从而防止功能模组200持续受到外力作用，以达到保护功能模组200的目的。
上述检测件可以安装于壳体100，并且该检测件靠近配合部330和卡钳370，从而可以准确地获知配合部330和卡钳370的配合状态。在另一些实施例中，检测件也可以安装于配合部330，从而使得检测件与配合部330及卡钳370之间的距离更小，从而更准确地获知配合部330和卡钳370的配合状态，更快速地对功能模组200受到外力作用的情况做出响应。
需要说明的是，上述的检测件可以采用位置传感器、接近开关等器件，控制件可以是控制器等器件，本发明实施例不限制检测件和控制件的具体种类。
活动挡板360可以整体设置于丝杠320的上方，或者，活动挡板360设有避让孔，丝杠320的一端穿过该避让孔，此时活动挡板360的尺寸较大，能够增大活动挡板360与卡钳370的接触面积，有利于两者之间的作用力更可靠地传递，同时，活动挡板360不会影响丝杠320转动。可选地，避让孔的形状可以与丝杠320的结构相匹配，例如，避让孔可以为圆孔，该圆孔的孔径可以大于丝杠320的外径，从而使得两者之间可以形成一定的间隙。当然，形状还可以是矩形，三角形等。
为了更可靠地发挥弹性件350的作用，可以将弹性件350的数量设置为多个，其中包括第一弹性件351和第二弹性件352，第一弹性件351的一端和第二弹性件352的一端均与活动挡板360相连，且第一弹性件351和第二弹性件352分别位于丝杠320的两侧。随着弹性件350的数量增加，活动挡板360与配合部330之间的连接点将会增加，从而使得两者连接时的可靠性更高，且结构更稳定。此外，当功能模组200受到外力作用时，多个弹性件350可以吸收更多的外力，防止功能模组200和驱动机构损坏。
弹性件350可以直接与配合部330靠近开口110的一端相连接，采用此种结构时，由于配合部330靠近开口110的一端的尺寸相对较小，因此不便于弹性件350和配合部330之间的连接。基于此，可选的实施例中，丝母套组还包括连接板340，连接板340连接于配合部330靠近开口110的一端，第一弹性件351的一端和第二弹性件352的一端均通过连接板340与配合部330相连。功能模组200需要通过开口110回缩至壳体100之内时，驱动源310通过丝杠320带动配合部330移动，连接板340随之移动并带动卡钳370沿远离开口110的方向移动，从而带动功能模组200向壳体100内移动。
连接板340的尺寸适当增大，可更可靠地与弹性件350和卡钳370相连接，同时，更便于使弹性件350的延伸方向平行于功能模组200的移动方向，从而使得弹性件350更高效地传递驱动力，同时更好地吸收功能模组200受到的外力。
可选地，上述连接板340和配合部330可以分体设置，即两者可以分体成型后再装配到一起，或者，连接板340和配合部330一体成型，从而提高两者所形成结构的结构强度。
弹性件350和卡钳370的布置位置比较集中，因此两者之间容易出现干涉。有鉴于此，一种可选的实施例中，卡钳370具有避让凹部372，弹性件350的至少一部分位于该避让凹部372内。设置避让凹部372时，卡钳370和弹性件350不容易干涉，因此两者可以设置得更集中，使得功能模组200和驱动机构所形成的结构更加紧凑，使得两者占用的空间更小，有利于电子设备内零部件的堆叠。
卡钳370与配合部330限位配合的情况下，在一种可选的方案中，卡钳370可以设有配合孔，配合部330可以与该配合孔配合。另一种可选的方案中，卡钳370具有联动凹部371，该联动凹部371与配合部330限位配合。这里的联动凹部371首先可以在功能模组200的移动方向上贯通卡钳370，同时还可以沿垂直于该移动方向的方向延伸至卡钳370的表面，此种联动凹部371的结构类似于凹槽，相对而言，该联动凹部371对卡钳370的装配方向的限制更少，因此便于实现卡钳370与驱动机构的组装，使得电子设备的组装效率更高。
本发明实施例公开的电子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)、电子游戏机等设备，本发明实施例不限制电子设备的具体种类。
本发明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。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
