本申请要求于2020年02月25日提交中国专利局、申请号为202010117703.8、申请名称为“终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，特别涉及一种终端。
背景技术
终端由于其使用时自身姿态的不确定性，在实现无线通信的过程中，天线需尽可能降低自身方向性系数，以更好的覆盖各个方位通信的需求。同时，对于无线保真(Wireless Fidelity，Wi-Fi)天线，由于行业规定，需要具有较低的方向性系数，否则需要具有较低的天线发射功率。对于传统的终端Wi-Fi天线，天线的方向性系数的优化主要通过调整天线在整机的布局位置来实现。如果天线布局位置受限，则会受到整机环境影响，难以控制方向性系数，因此传统的Wi-Fi天线在天线布局位置受限时会由于天线方向性系数较高而限制天线的发射功率。
发明内容

第一方面，本申请技术方案提供了一种终端，包括：终端主体部和电子配件部；终端主体部上设置有Wi-Fi天线装置，Wi-Fi天线装置具有封闭式缝隙天线，封闭式缝隙天线包括主体直线缝隙以及分别从主体直线缝隙两端向同一侧弯折并延伸形成的第一缝隙和第二缝隙，第一缝隙和第二缝隙均垂直于主体直线缝隙，电子配件部位于主体直线缝隙的侧面。
可选地，终端主体部为平板状结构，终端主体部包括相对的两个主表面以及连接两个主表面的侧表面，封闭式缝隙天线的天线缝隙设置于两个主表面中的一者上，电子配件部可拆卸连接于终端主体部的侧表面的相对位置。
可选地，封闭式缝隙天线的天线缝隙为“U”字型或非封闭的“回”字型。
可选地，终端主体部为平板电脑，电子配件部为手写笔。
可选地，终端为笔记本电脑，终端主体部为电脑主体部，终端主体部包括相对的上壳体、下壳体以及连接上壳体和下壳体的四个侧壳体；电子配件部为显示屏，终端主体部在一个侧壳体一侧的边缘具有转轴区，电子配件部在转轴区转轴连接于终端主体部；封闭式缝隙天线位于转轴区对应的侧壳体上。
可选地，笔记本电脑在收纳状态下，电子配件部的显示面与终端主体部的上壳体 相对；终端主体部的上壳体为与封闭式缝隙天线电连接的地板。
可选地，封闭式缝隙天线的天线缝隙为非封闭的“回”字型。
可选地，封闭式缝隙天线的天线缝隙的末端位于天线缝隙靠近终端主体部的上壳体的一侧。
本申请实施例中的终端，通过在主体直线缝隙两端设置向同一侧弯折的第一缝隙和第二缝隙，使得第一缝隙和第二缝隙处的电场具有相互抵消的作用，从而可以在Wi-Fi天线布局位置受限时减弱天线在同一个方向上的辐射强度，即降低了天线的方向性系数，从而提高天线的发射功率。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
在对本申请实施例进行介绍之前，首先对现有技术的问题的进行简单说明，如图1所示，图1为现有技术中一种平板电脑的结构示意图，图2为图1中平板电脑的Wi-Fi天线辐射方向图，图1中示意了一种平板电脑结构示意图，平板电脑主体1’的侧面设置有手写笔，由于外观等其他原因限制Wi-Fi天线3’的位置位于靠近手写笔处，一般采用直线的封闭缝隙天线设计。以2.4GHz的Wi-Fi天线为例，如图2所示，由于手写笔对于天线辐射的影响，会导致天线缝隙上下两侧的辐射强度差异较大，即导致天线的方向性系数较高，达到7.5dBi。另外，如图3至图8所示，图3为现有技术中一种笔记本电脑的侧视图，图4为图3中笔记本电脑的一种立体结构示意图，图5为 图4中B区域的一种放大结构示意图，图6为图3中笔记本电脑部分侧面的放大结构示意图，图7为图6中AA’向的剖面结构示意图，图8为图3中笔记本电脑的Wi-Fi天线辐射方向图，笔记本电脑包括屏幕4’和主体部5’，主体部5’包括设置上壳体51’和下壳体52’以及靠近转轴的侧面壳体53’，如图5所示，图5中省略了屏幕4’，在靠近转轴的侧面壳体53’具有凹陷的C区域，C区域中设置有Wi-Fi天线6’，其中图5中省略了Wi-Fi天线6’的具体结构，如图6和图7所示，考虑到尽量保持产品外观面，一般将天线6’布局在凹陷的C区域内。常规的天线6’采用(Inverted-F Antenna，IFA)倒F天线形式设计，馈电位置D在天线6’与下壳体52’之间，下壳体52’接地。以2.4GHz的Wi-Fi天线为例，如图8所示，由于屏幕4’对天线的影响，会导致天线上下两侧的辐射强度差异较大，即导致天线的方向性系数较高，达到8dBi以上。
以下对本申请实施例进行说明，如图9和图10所示，图9为本申请实施例中一种终端的立体结构示意图，图10为图9中终端的俯视图，本申请实施例提供一种终端，包括：终端主体部1和电子配件部2；终端主体部1上设置有Wi-Fi天线装置，Wi-Fi天线装置具有封闭式缝隙天线3，封闭式缝隙天线3包括主体直线缝隙30以及分别从主体直线缝隙30两端向同一侧弯折并延伸形成的第一缝隙31和第二缝隙32，第一缝隙31和第二缝隙32均垂直于主体直线缝隙30，电子配件部2位于主体直线缝隙30的侧面。
具体地，封闭式缝隙天线3的缝隙两侧具有一致的电场方向，例如图10中所示的结构，主体直线缝隙30处的电场方向为从上向下，第一缝隙31处的电场方向为从左向右，第二缝隙32处的电场方向为从右向左，由于第一缝隙31和第二缝隙32相对，因此，第一缝隙31和第二缝隙32处的电场具有相互抵消的作用，而非叠加的作用，从而减弱了天线在同一个方向上的辐射增强。因此，当封闭式缝隙天线3的设置位置被限定时，虽然封闭式缝隙天线3的辐射方向会受到其主体直线缝隙30侧面的电子配件部2所影响，但是，仍然可以通过对封闭式天线3的缝隙弯折设计而降低天线的方向性系数。如图11所示，图11为图10中终端的Wi-Fi天线辐射方向图，可以看出，和图2相比，图11中终端的Wi-Fi天线方向性系数较低，接近3.5dBi，低于采用直线式缝隙天线的方向性系数。
本申请实施例中的终端，通过在主体直线缝隙两端设置向同一侧弯折的第一缝隙和第二缝隙，使得第一缝隙和第二缝隙处的电场具有相互抵消的作用，从而可以在Wi-Fi天线布局位置受限时减弱天线在同一个方向上的辐射强度，即降低了天线的方向性系数，从而提高天线的发射功率。
可选地，终端主体部1为平板状结构，终端主体部1包括相对的两个主表面以及连接两个主表面的侧表面，封闭式缝隙天线3的天线缝隙设置于两个主表面中的一者上，电子配件部2可拆卸连接于终端主体部1的侧表面的相对位置。限制封闭式缝隙天线3需要位于如图9和图10中所示的位置时，若电子配件部2设置于终端主体部1侧表面处时，会对封闭式缝隙天线3的天线方向性造成不良影响，然而在本申请实施例中，由于封闭式缝隙天线3的弯折设置方式，降低了电子配件部2对于天线方向性的不良影响，降低了天线的方向性系数。
可选地，如图10和图12所示，图12为本申请实施例中另一种终端的俯视图，封闭式缝隙天线3的天线缝隙为“U”字型或非封闭的“回”字型。
具体地，在图10所示的结构中，主体直线缝隙30、第一缝隙31和第二缝隙32形成“U”字型结构，以形成封闭式缝隙天线3。在图12所示的结构中，封闭式缝隙天线3的天线缝隙除了包括主体直线缝隙30、第一缝隙31、第二缝隙32，还包括第三缝隙33和第四缝隙34，第三缝隙33从第一缝隙31的下端向右弯折延伸，第四缝隙34从第二缝隙32的下端向左弯折延伸，主体直线缝隙30、第一缝隙31、第二缝隙32、第三缝隙33和第四缝隙34形成非封闭的“回”字型结构，以形成封闭式缝隙天线3。如图13所示，图13为图12中终端的Wi-Fi天线辐射方向图，可以看出，和图2相比，如图13中终端的Wi-Fi天线方向性系数较低，接近3.5dBi，低于采用直线式缝隙天线的方向性系数。
可选地，如图9、图10和图12所示，终端主体部1为平板电脑，电子配件部2为手写笔。手写笔可以吸附于平板电脑的侧面，此时，封闭式缝隙天线3的天线缝隙位于靠近平板电脑的后壳，且临近吸附有手写笔的侧边，当手写笔吸附于平板电脑上时，由于封闭式缝隙天线3的弯折设置方式，降低了手写笔对于天线方向性的不良影响，降低了天线的方向性系数。
可选地，如图14、图15和图16所示，图14为本申请实施例中另一种终端的立体结构示意图，图15为图14中封闭式缝隙天线处的放大结构示意图，图16为图15中EE’向的剖面结构示意图，终端为笔记本电脑，终端主体部1为电脑主体部，终端主体部1包括相对的上壳体11、下壳体12以及连接上壳体11和下壳体12的四个侧壳体13；电子配件部2为显示屏，终端主体部1在一个侧壳体13一侧的边缘具有转轴区4，电子配件部2在转轴区4转轴连接于终端主体部1；封闭式缝隙天线3位于转轴区4对应的侧壳体13上。
具体地，例如，封闭式缝隙天线3的天线缝隙可以为侧壳体13的缝隙，或者，封闭式缝隙天线3的天线缝隙可以为设置于侧壳体13上导电板的缝隙。封闭式缝隙天线3同样包括主体直线缝隙30以及分别从主体直线缝隙30两端向同一侧弯折并延伸形成的第一缝隙31和第二缝隙32，第一缝隙31和第二缝隙32均垂直于主体直线缝隙30，电子配件部2位于主体直线缝隙30的侧面。由于封闭式缝隙天线3的位置限制于转轴区4对应的侧壳体13上，因此，显示屏会对封闭式缝隙天线3的天线方向性造成不良影响，在本申请实施例中，由于第一缝隙31和第二缝隙32处的电场具有相互抵消的作用，从而减弱了天线在同一个方向上的辐射增强，即降低了天线的方向性系数，从而提高天线的发射功率。
可选地，如图14、图15和图16所示，笔记本电脑在收纳状态下，电子配件部2的显示面与终端主体部1的上壳体11相对；终端主体部1的上壳体11为与封闭式缝隙天线3电连接的地板。
具体地，终端主体部1的上壳体11为与封闭式缝隙天线3电连接的地板时，即终端主体部1的上壳体11接地。上壳体11位于显示屏和封闭式缝隙天线3之间，显示屏对于封闭式缝隙天线3的辐射影响是使更多的辐射波束向上，而地板对天线的辐射具有反射的作用，即上壳体11会使天线的辐射波束向下反射，因此，通过设置上壳体 11作为地板可以降低显示屏对于封闭式缝隙天线3辐射方向的不良影响，进一步降低天线的方向性系数，从而提高天线的发射功率。
可选地，如图14、图15和图16所示，封闭式缝隙天线3的天线缝隙为非封闭的“回”字型。由于通常笔记本电脑的侧壳体13的高度较小，为了增加天线长度以满足要求，设置封闭式缝隙天线3的天线缝隙为非封闭的“回”字型，即封闭式缝隙天线3还包括第三缝隙33和第四缝隙34，第三缝隙33从第一缝隙31的上端向右弯折延伸，第四缝隙34从第二缝隙32的上端向左弯折延伸，主体直线缝隙30、第一缝隙31、第二缝隙32、第三缝隙33和第四缝隙34形成非封闭的“回”字型结构，以形成封闭式缝隙天线3。
可选地，如图14、图15和图16所示，封闭式缝隙天线3的天线缝隙的末端位于天线缝隙靠近终端主体部1的上壳体11的一侧，即第三缝隙33和第四缝隙34的末端均位于主体直线缝隙30靠近上壳体11的一侧，例如，其中第三缝隙33的末端连通至上壳体11处，在该处设置有馈电点35，通过馈电点35以及上壳体11分别实现馈电。如图17所示，图17为图14中终端的Wi-Fi天线辐射方向图，可以看出，和图8相比，图17中终端的Wi-Fi天线方向性系数较低，接近5.2dBi，低于IFA天线的方向性系数。
