Description

设备天线及可折叠设备 技术领域
本公开涉及(但不限于)通信领域。
背景技术
终端设备正趋于更小更薄更轻，却能够拥有更多的功能，这势必在终端设备的天线设计上有更高的要求。实现的功能越多就会使手机内部空间紧张，留给天线的空间会越来越少，而如何在更小的空间内实现相同甚至更好的性能是现在终端天线设计的难点之一。
双屏设备(如手机)的出现进一步加大了天线的设计难度。双屏手机的硬件设计上更加复杂，留给天线的空间会更少，同时屏幕打开、闭合状态都会很大程度上影响天线的性能，如果还按照传统手机天线来设计会有很大的困难。
发明内容
根据本公开的一个实施例，提供了一种用于电子设备的天线，所述电子设备包括设置有主板的本体和与所述本体分开设置的第一屏幕，所述天线包括：馈点，其设置在所述本体所在的一侧；第一天线，其与所述馈点连接，所述第一天线从所述本体所在的一侧延伸至所述第一屏幕所在的一侧；第二天线，其设置在所述本体所在的一侧；以及转轴，其跨接在所述本体和所述第一屏幕之间，其中，所述转轴与所述第一天线之间设置有开关。

附图说明
此处所说明的附图用来提供对本公开的进一步理解，构成本公开的一部分，本公开的示意性实施例及其说明用于解释本公开，并不构成对本公开的不当限定。在附图中：
图1是根据本公开实施例的用于电子设备的天线的结构平面示意图；
图2是根据本公开实施例的天线的转轴处电路示意图；

具体实施方式
下文中将参考附图并结合实施例来详细说明本公开。需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。
需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
随着科学技术的不断发展，手机也越做越小、越做越薄，但是功能却越来越多。相关技术中的手机天线的工艺也在不断发展，从最开始的外置螺旋天线到内置的金属平面倒F天线(The Planar Inverted-F Antenna，PIFA)，再到柔性电路板(Flexible Printer Circuit，FPC)、激光直接成型(Laser Direct Structuring，LDS)的天线，直到金属边框天线。如何在有限的空间设计出满足要求的天线，对于折叠设备或者翻盖设备，相关技术中的天线都是单一的天线，导致其应用场景有限。
相关技术中的折叠屏手机或翻盖手机都是通过使用转轴将手机的两部分连接，而转轴的使用会占用一定的手机空间。现在的手机频段越来越多，走线的面积也越来越大，这就会导致难以兼顾结构和天 线设计。如果将天线设计在转轴附近，则天线的性能势必会受到转轴的干扰，导致天线的性能不理想。双屏手机打开和闭合状态也会影响到天线的状态，如果这两种状态的差异过大会严重影响到天线的调试，增大天线的调试难度。
图1是根据本公开实施例的用于电子设备的天线的结构平面示意图。
如图1所示，电子设备可以包括设置有主板的本体1和第一屏幕2，天线可以包括：设置在本体1所在的一侧的馈点11，馈点11可引入信号；与馈点11连接的第一天线12，第一天线12从本体1所在的一侧延伸至第一屏幕2所在的一侧；设置在本体1所在的一侧的第二天线13；以及跨接在本体1和第一屏幕2之间的转轴14，转轴14与第一天线12之间设置有开关15。
根据本公开实施例，通过将转轴14用作天线的一部分，既节省了天线的空间、降低了成本，又降低了转轴对天线的影响。此外，还可以通过本体1和第一屏幕2的打开、闭合两种状态来切换天线的工作状态，使天线在不同的使用场景下切换到不同的工作频段，提升天线性能，解决了相关技术中的天线干扰大且性能弱的技术问题。
在一个实施例中，天线12布置在本体1和第一屏幕2的净空区20内。
在一个实施例中，本体1可以包括第二屏幕。当本体1包括第二屏幕时，该电子设备是双屏设备，例如，双屏手机。本体1也可以包括键盘，此时，该电子设备是翻盖设备，例如，翻盖手机。此外，本体1和第一屏幕2可以按照其他形式进行组合，例如，电子设备可以是可旋转设备。
在一个实施例中，第一天线12的长度可以为四分之一波长。
在一个实施例中，开关15可以为单刀单置开关。
在一个实施例中，开关15可以与馈点11相邻，从而可以在装配时节约更多的空间，减少电路的走线。
在一个实施例中，在本体1和第一屏幕2打开时，开关15可以处于导通状态，并且在本体1和第一屏幕2闭合时，开关15可以处 于断开状态。
在一个实施例中，开关15可以与设置在本体1或第一屏幕2上的霍尔传感器连接。可以通过霍尔传感器的不同状态来控制开关15，并且可以通过本体1和第一屏幕2打开和闭合来切换霍尔传感器的状态。
在一个实施例中，第一天线12和第二天线13分别在转轴14的两侧接地。第一天线12可以经开关15和转轴14与第一屏幕2侧的地板相连，第二天线13可以在本体1侧直接与地板相连，起到寄生天线的作用。
本公开实施例还提供了一种可折叠设备，包括设置有主板的本体1、第一屏幕2和如图1所示的天线。
在一个实施例中，可折叠设备还可以包括霍尔传感器，其设置在本体1或第一屏幕2上，并且与开关15连接。
在一个实施例中，本体1可以包括第二屏幕。
如图1所示，天线包括馈点11，第一天线12、第二天线13、转轴14和开关15组成。本实施例仅示意地示出通过转轴14连接本体1和第一屏幕2，其他类型的连接方式也可以应用于本公开的方案。
当本体1包括第二屏幕时，转轴14可以跨接在两个屏幕之间，起到连接作用。转轴14在主屏幕(即，第二屏幕)侧不接地，而在副屏幕(即，第一屏幕)侧接地。
馈点11可以位于主屏幕侧，信号从馈点11进入天线12。天线12可以布置在主屏幕和副屏幕的净空区20内，并且天线12的长度大约在四分之一波长。
第一天线12在馈点11的相邻位置处通过开关15接入转轴14，然后经过转轴14与副屏幕侧的地板相连。开关15可以为单刀单置开关。
第二天线13可以在主屏幕侧直接与地板相连，起到寄生天线的作用。
当主、副屏幕打开时，开关15可以导通，并且天线切换到第一状态，即，第一天线12通过转轴14接地，形成一个传统的IFA天线， 并通过与旁边的寄生天线(即，第二天线13)的耦合作用，形成一个低频850MHz和高频2.4GHz的双频天线；当主、副屏幕闭合时，开关15可以断开，并且天线切换到第二状态，即，第一天线12形成一个单极子天线，通过与寄生天线(即，第二天线13)的耦合作用，形成一个低频900MHz和中频1.7-2.1GHz的多频天线。开关15可以由霍尔器件控制其通断。通过以上操作实现了天线在不同频段之间的切换。
图2是根据本公开实施例的天线的转轴处电路示意图。
如果图2所示，转轴14连接开关15，开关15与霍尔器件30连接，并且单刀单置开关15与馈点11连接。馈点11可以作为天线馈源。
在实验室通过制作治具对这两种天线状态分别进行了无源测试，可以使天线在B5/B40与B1/B3/B8这两组频段之间切换，也可以根据需要调整工作频段。
图3是根据本公开实施例的天线在第一状态下的回波损耗示意图，并且图4是根据本公开实施例的天线在第二状态下的回波损耗示意图。
参见图3和图4，这两种状态的低频效率均超过了30％，高频均超过了40％，可以证明根据本公开实施例的天线可正常使用。
根据公开实施例，将转轴作为天线的一部分，通过是否连接到接地的转轴来控制天线的状态，充分利用了转轴本身的金属特性，在紧张的结构设计中，节省了部分天线的走线空间。
根据本公开实施例，通过将转轴作为天线的一部分节省了天线占用的空间，同时利用天线转轴来改变天线的不同状态，从而达到提升天线性能的目的。通过将转轴用作天线的一部分，既节省了天线的空间、降低了成本，又降低了转轴对天线的影响。此外，还可以通过双屏的打开、闭合两种状态来切换天线的工作状态，使手机天线在不同的使用场景下切换到不同的工作频段，提升天线性能。
以上所述仅为本公开的实施例，并不用于限制本公开。对于本领域的技术人员来说，本公开可以有各种更改和变化。凡在本公开的 精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
