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，与天线辐射枝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，与天线辐射枝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；
所述第一壳体包括第一导电本体和与所述第一导电本体电连接的第一天线辐射支；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一侧与所述第一导电本体之间设有第二绝缘区；
所述第二壳体包括第二导电本体和与所述第二导电本体电连接的第二天线辐射支；所述第二导电本体接地，所述第二天线辐射支的第一端与所述第二导电本体之间设有第三绝缘区，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四绝缘区；
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三绝缘区至少部分相对，所述第二绝缘区与所述第四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，第一绝缘区与第三绝缘区至少部分相对，第二绝缘区与第四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，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。

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包括第一导电本体11和与第一导电本体11电连接的第一天线辐射支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的第一侧与第一导电本体11之间设有第二绝缘区14；
第二壳体2包括第二导电本体21和与第二导电本体21电连接的第二天线辐射支22；第二导电本体21接地，第二天线辐射支22的第一端与第二导电本体21之间设有第三绝缘区23，第二天线辐射支22的第一侧与第二导电本体21之间设有第四绝缘区24；
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与第三绝缘区23至少部分相对，第二绝缘区14与第四绝缘区24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。上述第一天线辐射支12与第一导电本体11电连接，可以是第一天线辐射支12的第二端与第一导电本体11电连接；更具体地，上述第一天线辐射支12可以是由第一导电本体11延伸形成。上述第一天线辐射支12可以是一字型或L型。
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。上述第二天线辐射支22与第二导电本体21电连接，可以是第二天线辐射支22的第二端与第二导电本体21电连接；更具体地，上述第二天线辐射支22可以是由第二导电本体11延伸形成。上述第二天线辐射支22可以是一字型或L型。上述第二天线辐射支22的长度与上述第一天线辐射支12的长度的比值介于三分之二至三分之四之间。
上述馈电点121可以是用于与天线馈源电连接的点；此处，天线馈源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，第一绝缘区与第三绝缘区至少部分相对，第二绝缘区与第四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，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 1和H 2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两个天线谐振模态，H 1-1和H 2-1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两个天线谐振模态，H 1-2和H 2-2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两个天线谐振模态。
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 1和H 2分别对应的两个天线谐振模态H 1-1和H 2-1之外，还由第二天线辐射支22额外产生了两个天线谐振模态H 1-2和H 2-2，显然，天线谐振模态H 1-1、H 2-1、H 1-2和H 2-2的总带宽大于天线谐振模态H 1和H 2的总带宽，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 1-1的带宽较天线谐振模态H 1的带宽更宽，天线谐振模态H 2-1的带宽较天线谐振模态H 2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。
另外，由于第一天线辐射支12与第一导电本体11电连接，第二天线辐射支与第二导电本体电连接，从而能够减少第一壳体和第二壳体上的断口数量，进而能够使得移动终端的外观效果更好。
可选地，第一壳体1与第二壳体2处于闭合状态时，第一绝缘区13与第三绝缘区23相互对齐和/或第二绝缘区14与第四绝缘区14相互对齐。
这样，由于第一绝缘区与第三绝缘区相互对齐时，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四绝缘区相互对齐时，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与第二天线辐射22支相互对齐。
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与第二天线辐射支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，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。

上述第一天线辐射支12与第二天线辐射支22间隔0.3毫米至2毫米，可以是第一天线辐射支12与第二天线辐射支22之间的间隔大于或等于0.3毫米且小于或等于2毫米，例如，0.5毫米。
这样，由于第一绝缘区介于0.3毫米至3毫米之间，第二绝缘区介于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。
由于第三绝缘区介于0.3毫米至3毫米之间，第四绝缘区介于0.3毫米至8毫米之间，从而既能够使得第二天线辐射支的辐射能力较好，也能够使得第二壳体的外观效果较好。
由于第四绝缘区的宽度大于或等于第二绝缘区的宽度，且第三绝缘区的宽度大于或等于第一绝缘区的宽度，从而能够使得第二天线辐射支的辐射能力更好。
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。

这样，由于通过增加第三天线辐射支能够进一步扩大第一天线辐射支的辐射空间，通过增加第四天线辐射支能够进一步扩大第二天线辐射支的辐射空间，且第一壳体与第二壳体处于闭合状态时，第三天线辐射支与第四天线辐射支也能够电容耦合，因而能够进一步提升天线的辐射能力和增加天线带宽。
