技术领域
本公开涉及通信技术领域，尤其涉及一种移动终端。
背景技术
随着用户对大屏幕的追求，重叠屏移动终端(例如，折叠屏手机)逐渐进入人们的视野。重叠屏移动终端通常包括以下两种，一种是由一块整的屏幕通过弯曲对折或推拉形成两个盖体；另一种是由两个单独的屏幕对折或推拉形成两个盖体，两个盖体打开时两个屏幕处于同一平面而拼凑成一个大屏幕。
为了满足用户对移动终端的外观需求，目前市面上的重叠屏移动终端通常采用金属材质的壳体，同时，将用于辐射天线能量的天线辐射支设置在其中一个盖体的壳体上，当重叠屏移动终端的两个盖体重叠时，与天线辐射支相对的是另一盖体的金属壳体，这导致对天线辐射空间的压缩较大，进而导致天线的辐射能力较差。
发明内容
本公开实施例提供一种移动终端，以解决相关技术中的重叠屏移动终端，由于两个盖体重叠时，与天线辐射支相对的是另一盖体的金属壳体，这导致对天线辐射空间的压缩较大，进而导致天线的辐射能力较差的问题。
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，包括能够相对运动到至少部分重叠的闭合状态的第一壳体和第二壳体；
所述第一壳体包括间隔设置的第一导电本体和第一天线辐射支，所述第一导电本体接地，所述第一天线辐射支上设有馈电点，所述第一天线辐射支 与匹配电路电连接；所述第一天线辐射支的第一端与所述第一导电本体之间设有第一绝缘区，所述第一天线辐射支的第二端与所述第一导电本体之间设有第二绝缘区，所述第一天线辐射支的第一侧与所述第一导电本体之间设有第三绝缘区；
所述第二壳体包括间隔设置的第二导电本体和第二天线辐射支，所述第二导电本体接地，所述第二天线辐射支上设有第一接地点；所述第二天线辐射支的第一端与所述第二导电本体之间设有第四绝缘区，所述第二天线辐射支的第二端与所述第二导电本体之间设有第五绝缘区，所述第二天线辐射支的第一侧与所述第二导电本体之间设有第六绝缘区；
所述第一壳体与所述第二壳体处于所述闭合状态时，所述第一天线辐射支分别与所述第二天线辐射支、所述第二导电本体存在间隔，所述第二天线辐射支与所述第一导电本体存在间隔，所述第一绝缘区与所述第四绝缘区至少部分相对，所述第二绝缘区与所述第五绝缘区至少部分相对，所述第三绝缘区与所述第六绝缘区至少部分相对，所述第一天线辐射支与所述第二天线辐射支电容耦合。
在本公开实施例中，由于第一壳体与第二壳体处于闭合状态时，第一绝缘区与第四绝缘区至少部分相对，第二绝缘区与第五绝缘区至少部分相对，第三绝缘区与第六绝缘区至少部分相对，从而使得第一壳体与第二壳体处于闭合状态时，与第一天线辐射支相对的是第二天线辐射支或者是第二天线辐射支和绝缘区，这样，能够减小对天线辐射空间的压缩，进而能够提升天线的辐射能力；同时；同时，由于第一壳体与第二壳体处于闭合状态时，第一天线辐射支与第二天线辐射支电容耦合，从而使得第一天线辐射支辐射的天线能量能够通过电容耦合被传递至第二天线辐射支进行二次辐射，这样，能够进一步提升天线的辐射能力和增加天线带宽。
附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳 动性的前提下，还可以根据这些附图获得其他的附图。
图1是本公开一实施例提供的移动终端的结构图之一；

图3是本公开一实施例提供的移动终端的举例图。
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和图2所示，本公开一实施例提供一种移动终端，包括能够相对运动到至少部分重叠的闭合状态的第一壳体1和第二壳体2；
第一壳体1包括间隔设置的第一导电本体11和第一天线辐射支12，第一导电本体11接地，第一天线辐射支12上设有馈电点121，第一天线辐射支12与匹配电路电连接；第一天线辐射支12的第一端与第一导电本体11之间设有第一绝缘区13，第一天线辐射支12的第二端与第一导电本体11之间设有第二绝缘区14，第一天线辐射支12的第一侧与第一导电本体11之间设有第三绝缘区15；
第二壳体2包括间隔设置的第二导电本体21和第二天线辐射支22，第二导电本体21接地，第二天线辐射支22上设有第一接地点221；第二天线辐射支22的第一端与第二导电本体21之间设有第四绝缘区23，第二天线辐射支22的第二端与第二导电本体21之间设有第五绝缘区24，第二天线辐射支22的第一侧与第二导电本体21之间设有第六绝缘区25；
第一壳体1与第二壳体2处于闭合状态时，第一天线辐射支12分别与第二天线辐射支22、第二导电本体21存在间隔，第二天线辐射支22与第一导电本体11存在间隔，第一绝缘区13与第四绝缘区23至少部分相对，第二绝缘区14与第五绝缘区24至少部分相对，第三绝缘区15与第六绝缘区25至少部分相对，第一天线辐射支12与第二天线辐射支22电容耦合。
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，也可以是通过滑轨或滑槽连接。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可以是通过折叠相对运动至至少部分重叠的闭合状态；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可以是通过滑动(例如，左右滑动或上下滑动)相对运动至至少部分重叠的闭合状态。
上述第一天线辐射支12的材质可以是任一导电体，例如，铜、不锈钢、镁合金、铝合金等。上述第二天线辐射支22的材质可以是任一导电体，例如，铜、不锈钢、镁合金、铝合金等。上述馈电点121可以是用于与信号源3电连接；信号源3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 mobile communication technology，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 mobile communication technology，5G)、无线保真(WIreless-Fidelity，WIFI)或全球定位系统(Global Positioning System，GPS)等射频模块。
上述第一天线辐射支12与匹配电路电连接至少可以通过以下方式中的其中一种来实现：其一，将匹配电路连接于馈电点121和信号源3之间，即此时，馈电点121通过匹配电路与信号源3电连接；其二，在第一天线辐射支12上另外设置一连接点122，将匹配电路与连接点122电连接并将该匹配电路接地。需要注意的是，此处的匹配电路既可以由电感和/或电容构成，也可以是由多路开关加多路电感和/或电容构成，还可以仅由导电线构成，当此处的匹配电路仅由导电线构成时，前述第二种方式中的“将匹配电路与连接点122电连接并将该匹配电路接地”可以理解为“将连接点122直接接地”。上述第一接地点221可以是用于与参考地电连接，即用于接地。
上述绝缘区也可以称为电绝缘区；上述各个绝缘区均可以是由非金属材料(例如，塑料)填充而成。需要指出的是，为了进一步提高空间利用率，在一些可选方案中，上述各个绝缘区内嵌设有接地或不接地的金属件，例如， 喇叭、摄像头、USB等，且这些金属件与天线辐射支之间存在间隔。上述至少部分相对可以理解为至少部分对齐。
在谐振频率方面，上述第一天线辐射支12的谐振频率与上述第二天线辐射支22的谐振频率可以相同的，也可以是不同的，例如，第一天线辐射支12可以是谐振于高频段(2.3吉赫～2.69吉赫)或中频段(1.71吉赫～2.17吉赫)，第二天线辐射支22可以是谐振于低频段(0.7吉赫～0.96吉赫)。另外，上述第一天线辐射支12可以谐振于一个频段也可以是谐振于多个频段；上述第二天线辐射支22可以谐振于一个频段也可以是谐振于多个频段；对此，本公开实施例不作限定。
在本公开实施例中，由于第一壳体与第二壳体处于闭合状态时，第一绝缘区与第四绝缘区至少部分相对，第二绝缘区与第五绝缘区至少部分相对，第三绝缘区与第六绝缘区至少部分相对，从而使得第一壳体与第二壳体处于闭合状态时，与第一天线辐射支相对的是第二天线辐射支或者是第二天线辐射支和绝缘区，这样，能够减小对天线辐射空间的压缩，进而能够提升天线的辐射能力；同时；同时，由于第一壳体与第二壳体处于闭合状态时，第一天线辐射支与第二天线辐射支电容耦合，从而使得第一天线辐射支辐射的天线能量能够通过电容耦合被传递至第二天线辐射支进行二次辐射，这样，能够进一步提升天线的辐射能力和增加天线带宽。
为了对本公开实施例的有益技术效果有一个更加直观的解释，此处举例说明，请参见图3，图3为相关技术中的移动终端与图1所示的移动终端在第一壳体与第二壳体处于闭合状态时所产生的天线谐振模态的对比示意图，其中，H 0表示相关技术中的移动终端在其第一壳体与第二壳体处于闭合状态时所产生的天线谐振模态，H 0-1表示图1所示的移动终端的第一天线辐射支12在它的第一壳体1与第二壳体2处于闭合状态时所产生的天线谐振模态，H 0-2表示图1所示的移动终端的第二天线辐射支22在它的第一壳体1与第二壳体2处于闭合状态时所产生的天线谐振模态。
由图3不难看出，图1所示的移动终端除了由第一天线辐射支12产生了与天线谐振模态H 0对应的天线谐振模态H 0-1之外，还由第二天线辐射支22额外产生了天线谐振模态H 0-2，天线谐振模态H 0-1与天线谐振模态H 0-2的总 带宽大于天线谐振模态H 0的带宽，这说明图1所示的移动终端的天线带宽较相关技术中的移动终端的天线带宽更宽，辐射能力更好。另外，如图3所示，天线谐振模态H 0-1的带宽较天线谐振模态H 0的带宽更宽，这说明第二天线辐射支22还能够扩大第一天线辐射支12的辐射空间，进而能够提升第一天线辐射支12的辐射能力。
可选地，第一接地点221通过调谐元件接地；和/或，
馈电点121位于第一天线辐射支12的第一端，第一接地点221位于第二天线辐射支22的第一端。
其中，上述调谐元件可以是固定匹配，例如，0欧姆电阻、电感或电容，也可以是多路开关加多路固定匹配，还可以是可变电容等。上述馈电点121可以是通过弹片、螺丝或柔性电路板(Flexible Printed Circuit，FPC)等与信号源3连接。
这样，由于第一接地点通过调谐元件接地，从而能够实现对第二天线辐射支的谐振频率的调节。
通过将馈电点设置于第一天线辐射支的第一端并将第一接地点设置于第二天线辐射支的第一端，能够使得第二天线辐射支的谐振模态的频率更加接近第一天线辐射支产生的谐振模态的频率，进而能够使得天线的辐射能力更好。
可选地，第一壳体与第二壳体处于闭合状态时，第一绝缘区13与第四绝缘区23相互对齐，和/或，第二绝缘区14与第五绝缘区24相互对齐，和/或，第三绝缘区15与第六绝缘区25相互对齐。
这样，由于第一绝缘区与第四绝缘区相互对齐时，第一天线辐射支的第一端的端面与第二天线辐射支的第一端的端面也会对齐，从而，既能够进一步降低第二导电本体对第一天线辐射支的干扰以及降低第一导电本体对第二天线辐射支的干扰，同时也能够改善第一天线辐射支与第二天线辐射支之间的耦合效果，进而能够进一步提升天线的辐射能力；另外还能够使得移动终端的外观更加对称和齐整。
由于第二绝缘区与第五绝缘区相互对齐时，第一天线辐射支的第二端的端面与第二天线辐射支的第二端的端面也会对齐，从而，既能够进一步降低 第二导电本体对第一天线辐射支的干扰以及降低第一导电本体对第二天线辐射支的干扰，同时也能够改善第一天线辐射支与第二天线辐射支之间的耦合效果，进而能够进一步提升天线的辐射能力；另外还能够使得移动终端的外观更加对称和齐整。
由于第三绝缘区与第六绝缘区相互对齐时，第一天线辐射支的第一侧与第二天线辐射支的第一侧也会对齐，从而，既能够降低第二导电本体对第一天线辐射支的干扰以及降低第一导电本体对第二天线辐射支的干扰，也能够改善第一天线辐射支与第二天线辐射支之间的耦合效果，进而能够提升天线的辐射能力；另外还能够使得移动终端的外观更加对称和齐整。
可选地，第二天线辐射支22的长度与第一天线辐射支12的长度的比值介于三分之二至三分之四之间。
可选地，第一壳体1与第二壳体2处于闭合状态时，第一天线辐射支12和第二天线辐射支22相互对齐。
其中，上述第一壳体1与第二壳体2处于闭合状态时，第一天线辐射支12和第二天线辐射支22相互对齐，可以理解为，第一天线辐射支12的形状和尺寸与第二天线辐射支22的形状和尺寸均一致，且当第一壳体1与第二壳体2处于闭合状态时，第一天线辐射支12和第二天线辐射支22完全对齐。
由于第一壳体与第二壳体处于闭合状态时，第一天线辐射支和第二天线辐射支相互对齐，从而不仅能够进一步降低第二导电本体对第一天线辐射支的干扰以及第一导电本体对第二天线辐射支的干扰，进而能够使天线的辐射能力更好；而且也能够进一步改善第一天线辐射支与第二天线辐射支之间的耦合效果，进而能够进一步提升天线的辐射能力；另外还能够使得移动终端的外观更加对称和齐整。
可选地，第一绝缘区的宽度和第二绝缘区的宽度均介于0.3毫米至3毫米之间，第三绝缘区的宽度介于0.3毫米至8毫米之间；和/或，

这样，由于第一绝缘区和第二绝缘区的宽度均介于0.3毫米至3毫米之间，第三绝缘区的宽度介于0.3毫米至8毫米之间，从而既能够使得第一天线辐射支的辐射能力较好，也能够使得第一壳体的外观效果较好。

由于第一壳体与第二壳体处于闭合状态时，第一天线辐射支与第二天线辐射支间隔0.3毫米至2毫米，从而既能够使得第一天线辐射支与第二天线辐射支之间的耦合效果较好，进而能够使得天线的辐射能力较好，也能够使得移动终端在第一壳体与第二壳体处于闭合状态时的外观效果较好。
