背景技术
为了实现移动支付、公交出行、读取NFC电子标签或给NFC卡片充值等功能，移动终端上需要设置近场通信(Near Field Communication，NFC)天线。NFC天线是通过磁场耦合进行通信的，一般采用线圈或等同于线圈的闭合环路来实现，工作时线圈或闭合环路的磁通量大小直接影响NFC天线的性能高低。
相关技术中的部分移动终端受结构或其它因素限制，无法采用常规方式绕制多匝线圈构成NFC天线，因而通常采用金属壳体结构作为NFC天线，这种采用金属壳体结构作为NFC天线的移动终端，其仅能依赖金属壳体形成一圈电流回路，即NFC天线的线圈匝数为1匝，NFC天线的磁通量较小，NFC天线的性能较差，这导致相关技术中的移动终端难以适用于对NFC天线性能要求较高的使用场景，例如，移动终端作为感应式读卡器使用的场景。
发明内容
本公开实施例提供一种移动终端及天线控制方法，以解决相关技术中的折叠屏移动终端因NFC天线的磁通量较小而导致难以适用于对NFC天线性能要求较高的使用场景的问题。
为解决上述技术问题，本公开是这样实现的：
第一方面，本公开实施例提供了一种移动终端，包括第一壳体和第二壳体，所述第一壳体和第二壳体的连接状态具有折叠状态或展开状态；
所述第一壳体的侧边设置有与所述第一壳体电隔离的第一辐射臂，所述第一辐射臂接地；所述第一壳体设置有第一电触点和第二电触点，所述第一电触点与所述第一辐射臂电连接，所述第二电触点与第一信号源电连接，所述第一信号源接地；
所述第二壳体的侧边设置有与所述第二壳体电隔离的第二辐射臂，所述第二辐射臂接地；所述第二壳体设置有第三电触点和第四电触点，所述第三电触点与所述第二辐射臂电连接，所述第四电触点接地；
所述第一壳体与所述第二壳体处于所述折叠状态时，所述第一电触点与所述第四电触点接触导通，所述第二电触点与所述第三电触点接触导通。
第二方面，本公开实施例还提供一种天线控制方法，应用于上述移动终端，包括：
在所述第一壳体与所述第二壳体处于所述展开状态时，控制所述开关处于导通状态；
在所述第一壳体与所述第二壳体处于所述折叠状态时，控制所述开关处于断开状态。
本公开实施例中，在移动终端处于折叠状态时，天线的工作路径依次经过两个壳体以构成具有两圈电流回路的闭合环路，能够大大提升天线的磁通量，进而能够提升移动终端在折叠状态时天线的性能，这样，只需将移动终端调整为折叠状态就能够使移动终端较好地适用于对天线性能要求较高的使用场景。故当应用于NFC天线时(即第一信号源采用NFC信号源时)，就能够在移动终端处于折叠状态时大大提升NFC天线的磁通量，这样，只需折叠移动终端就能够使移动终端较好地适用于对NFC天线性能要求较高的使用场景。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例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作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。
如图1至图3所示，本公开一实施例提供一种移动终端，包括第一壳体1和第二壳体2，第一壳体1和第二壳体2的连接状态具有折叠状态或展开状态；
第一壳体1的侧边设置有与第一壳体1电隔离的第一辐射臂3，第一辐射臂3接地；第一壳体1设置有第一电触点6和第二电触点7，第一电触点6与第一辐射臂3电连接，第二电触点7与第一信号源9电连接，第一信号源9接地；
第二壳体2的侧边设置有与第二壳体2电隔离的第二辐射臂4，第二辐射臂4接地；第二壳体2设置有第三电触点11和第四电触点12，第三电触点11与第二辐射臂4电连接，第四电触点12接地；
第一壳体1与第二壳体2处于折叠状态时，第一电触点6与第四电触点12接触导通，第二电触点7与第三电触点11接触导通。
其中，上述移动终端可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device) 等。
上述第一壳体1和第二壳体2可以是通过转轴连接，也可以是通过滑轨连接。当第一壳体1和第二壳体2通过转轴连接时，第一壳体1和第二壳体2可以是通过绕转轴转动的方式相对运动至折叠状态或展开状态。当第一壳体1和第二壳体2通过滑轨连接时，第一壳体1和第二壳体2可以是通过沿滑轨滑动的方式相对运动至折叠状态或展开状态。上述第一壳体1和上述第二壳体2还可以是通过其他的连接方式实现折叠和展开，对此，本公开实施例不作限定。
上述第一壳体1的侧边可以是第一壳体1的边框；参见图1和图2，上述第一辐射臂3与上述第一壳体1之间可以采用断口13进行电隔离，进一步地，考虑到移动终端的美观度，可以用非导电材料(例如，塑胶)填充第一辐射臂3与第一壳体1之间的断口13。上述第一电触点6的材质可以是金属或导电非金属；上述第二电触点7的材质可以是金属或导电非金属。
上述第二壳体2的侧边可以是第二壳体2的边框；参见图1和图2，上述第二辐射臂4与上述第二壳体2之间可以采用断口14进行电隔离，进一步地，考虑到移动终端的美观度，可以用非导电材料(例如，塑胶)填充第二辐射臂4与第二壳体2之间的断口14。上述第三电触点11的材质可以是金属或导电非金属；上述第四电触点12的材质可以是金属或导电非金属。
上述第一辐射臂3与上述第二辐射臂4、上述第一辐射臂3与上述第二壳体2、上述第一壳体1与上述第二辐射臂4可以是相互电隔离。上述第一信号源9可以是NFC信号源。
本公开实施例中，在移动终端处于折叠状态时，天线的工作路径(如图3所示，折叠状态下天线的工作路径为：第一信号源→第二电触点→第三电触点→第二辐射臂→第二接地点→第四电触点→第一电触点→第一辐射臂→第一接地点→第一信号源)依次经过两个壳体以构成具有两圈电流回路的闭合环路，能够大大提升天线的磁通量，进而能够提升移动终端在折叠状态时天线的性能，这样，只需将移动终端调整为折叠状态就能够使移动终端较好地适用于对天线性能要求较高的使用场景，即使得移动终端能够在折叠状态下较好地适用于对天线性能要求较高的使用场景。故当应用于NFC天线时(即 第一信号源采用NFC信号源时)，就能够在移动终端处于折叠状态时大大提升NFC天线的磁通量，这样，只需折叠移动终端就能够使移动终端较好地适用于对NFC天线性能要求较高的使用场景。
可选地，移动终端还包括开关8，第一电触点6通过开关8与第二电触点7电连接；
第一壳体1与第二壳体2处于展开状态时，开关8处于导通状态；第一壳体1与第二壳体2处于折叠状态时，开关8处于断开状态。
其中，上述开关8可以是用于导通或断开上述第一电触点6和上述第二电触点7之间的电连接，例如，当开关8处于导通状态时，上述第一电触点6和上述第二电触点7电导通；当开关8处于断开状态时，上述第一电触点6和上述第二电触点7电断开。
由于在移动终端处于折叠状态时，通过断开开关使天线的工作路径依次经过两个壳体以构成具有两圈电流回路的闭合环路，而在移动终端处于展开状态时，通过导通开关使天线的工作路径(展开状态下天线的工作路径为：第一信号源→第二电触点→开关→第一电触点→第一辐射臂→第一接地点→第一信号源)也能经过第一壳体以构成具有一圈电流回路的闭合环路，从而使得移动终端的天线在移动终端处于闭合状态或展开状态时均能够工作。
可选地，第一电触点6与第一辐射臂3的第一端的端部电连接，第一辐射臂3的第二端的端部接地，第三电触点11与第二辐射臂4的第一端的端部电连接，第二辐射臂4的第二端的端部接地。
这样，能够增加天线构成的电流回路的匝数(圈数)，这样，能够进一步提升天线的磁通量，进而能够进一步提升天线的性能。
可选地，第一辐射臂3具有第一连接点31和第一接地点32，第一连接点31与第一电触点6电连接，第一接地点32接地；第二辐射臂4具有第二连接点41和第二接地点42，第二连接点41与第三电触点11电连接，第二接地点42接地；
第一壳体1与第二壳体2处于折叠状态时，第一连接点31与第二连接点41相互对齐，第一接地点32与第二接地点42相互对齐。
可选地，第一壳体1与第二壳体2处于折叠状态时，第一辐射臂3与第 二辐射臂4相互对齐。
其中，上述第一辐射臂3与第二辐射臂4相互对齐，可以是指第一辐射臂3与第二辐射臂4的形状和尺寸相同，且二者在第一壳体1与第二壳体2处于折叠状态时相互对齐。
这样，由于第一辐射臂与第二辐射臂在第一壳体与第二壳体处于折叠状态时相互对齐，从而能够使得移动终端的外观更加齐整和美观。
可选地，第一壳体1与第二壳体2处于折叠状态时，第一电触点6与第四电触点12相互对齐，第二电触点7与第三电触点11相互对齐。
这样，由于第一壳体与第二壳体处于折叠状态时，第一电触点与第四电触点以及第二电触点与第三电触点均相互对齐，从而能够使得第一电触点与第四电触点之间以及第二电触点与第三电触点之间的接触导通效果更好。
可选地，第一辐射臂3与第二信号源15电连接，第二信号源15与第一信号源9为不同的信号源。
其中，上述第二信号源15可以是第二代手机通信技术规格(2-Generation wireless telephone technology，2G)、第三代移动通信技术(3rd-Generation，3G)、第四代移动通信技术(the 4th Generation mobile communication technology，4G)、第五代移动通信技术(5th-Generation，5G)、无线保真(WIreless-Fidelity，WIFI)或全球定位系统(Global Positioning System，GPS)等射频模块。
这样，由于第一辐射臂还与第二信号源电连接，从而使得辐射臂能够同时实现多种天线功能，例如，可以同时实现NFC天线功能和4G天线功能，这样，能够节省移动终端的装配空间和制造成本。
可选地，第二电触点7通过第一电感器5与第一信号源9电连接；和/或，
第四电触点12通过第二电感器10接地。
其中，上述第一电感器5可以是用于隔离频率大于预设阈值的电磁波，即在频率大于预设阈值时呈现高阻抗而在频率小于或等于预设阈值时呈现低阻抗；此处的预设阈值可以根据具体需求进行设定，对此，本公开实施例不作限制，例如，当应用于NFC天线时，预设阈值可以是13.56MHZ。
上述第二电感器10可以是用于隔离频率大于预设阈值的电磁波，即在频率大于预设阈值的时呈现高阻抗而在频率小于或等于预设阈值时呈现低阻抗； 此处的预设阈值可以根据具体需求进行设定，对此，本公开实施例不作限制，例如，当应用于NFC天线时，预设阈值可以是13.56MHZ。
这样，在第二电触点与第一信号源之间设置第一电感器和/或在第四电触点与第二接地点之间设置第二电感器，能够减小不同谐振频率的天线之间的相互干扰。例如，当第一信号源为NFC信号源，第二信号源为非NFC信号源时，由于NFC天线的谐振频率较低，而非NFC天线的谐振频率通常较高，因而通过设置第一电感器和/或第二电感器能够减小NFC天线和非NFC天线之间的相互干扰。

步骤401、在所述第一壳体与所述第二壳体处于所述展开状态时，控制所述开关处于导通状态；
在所述第一壳体与所述第二壳体处于所述折叠状态时，控制所述开关处于断开状态。
本公开实施例的天线控制方法，应用于上述实施例中的移动终端，在移动终端处于折叠状态时，通过断开开关使天线的工作路径依次经过两个壳体以构成具有两圈电流回路的闭合环路，能够大大提升天线的磁通量，进而能够提升移动终端在折叠状态时天线的性能，这样，只需将移动终端调整为折叠状态就能够使移动终端较好地适用于对天线性能要求较高的使用场景。
