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，下面将结合附图对本申请实施例的实施方式进行详细描述。
本申请实施例提供的一种电子设备，包括但不限于为手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、手持计算机、对讲机、上网本、POS机、个人数字助理(personal digital assistant，PDA)、可穿戴设备、虚拟现实设备、无线U盘、蓝牙音响/耳机、或车载前装等具有天线的移动或固定终端。
其中，本申请实施例中，以手机为上述电子设备为例进行说明，本申请实施例提供的手机可为可折叠的手机，图1和图2分别示出了折叠手机展开和合上的结构，参见图1所示，手机可以包括：第一金属中框10和第二金属中框100，第一金属中框10和第二金属中框100之间可以通过转动件50(例如转动件50可以为转轴、铰链或柔性板)转动相连。这样使得手机中的第一金属中框10和第二金属中框100可以绕着转动件50进行折叠和展开，应当理解的是，折叠手机还可以包括显示屏和后壳，其中，显示屏和后壳分别位于第一金属中框和第二金属中框的正反两面。显示屏为可弯折的柔性显示屏，后壳也为可弯折的柔性板。
其中，本申请实施例中，第一金属中框10和第二金属中框100可以如图1中的箭头方向左右折叠。而在其他示例中，第一金属中框10和第二金属中框100还可以上下折叠、对角线折叠或其他任意角度进行折叠。可以理解的，图1中示出的手机包括第一金属中框10和第二金属中框100这两个金属中框，以实现手机中两个显示屏的折叠，在其他示例中，手机还可以包括三个金属中框，这样实现了手机中三个显示屏可折叠。
其中，第一金属中框10和第二金属中框100的其中一个可以为手机主屏对应的金属中框，另一个可以为手机副屏对应的金属中框，例如，第一金属中框10可以为主屏对应的主中框，第二金属中框100可以为副屏对应的副中框。折叠时，将副中框折叠到主中框上，当副中框折叠到主中框上时，手机的主屏和副屏可以相对，或者手机的主屏和副屏可以相互背离，本申请实施例中，第一金属中框10和第二金属中框100沿着图1中的箭头方向折叠后，手机的主屏和副屏相互背离，即手机折叠后手机的正反面均为显示屏，此时用户可以使用主屏进行显示，也可以使用副屏进行显示。
本申请实施例中，具体以第一金属中框10为主中框，第二金属中框100为副中框为例进行说明，参见图1所示，第一金属中框10的一侧边与第二金属中框100相连，第一金属中框10的另一侧边上设有侧端盖203，当第二金属中框100折叠到第一金属中框10上时，此时，侧端盖203与第二金属中框100上的显示屏可以平齐。
其中，本申请实施例中，为了防止第二金属中框100与第一金属中框10折叠后自动打开，具体的，如图1所示，在侧端盖203上设有按钮202，同时在按钮202下方设有卡 扣201，卡扣201的一端从侧端盖203的内侧面向外伸出，按钮202可以驱动卡扣201移动。相应的，第二金属中框100上设有与卡扣201配合的卡口(未示出)，这样当第二金属中框100折叠到第一金属中框10上时，此时卡扣201卡入卡口实现对第二金属中框100锁住的目的。当第二金属中框100需要打开时，此时，向下按动按钮202，按钮202驱动卡扣201从卡口中脱离，第二金属中框100可以向外展开。所以，本申请实施例中，通过按钮202、卡扣201和卡口配合实现了第二金属中框100与第一金属中框10折叠后的卡合作用，防止了第二金属中框100折叠到第一金属中框10上时向上翘起而影响用户对手机副屏的使用。
其中，本申请实施例中，为了实现手机在展开时显示面具有高屏占比的目的，如图2所示，可以将摄像头204和闪光灯205设置在侧端盖203上，在图2中，侧端盖203的顶端处依次间隔设置四个摄像头204。需要说明的是，摄像头204的设置数量包括但不限于为4个，还可以设置三个摄像头204等。本申请实施例中，通过将摄像头204、闪光灯205设置在侧端盖203上。这样手机展开时，显示面上避免了设置摄像头204和闪光灯205而造成屏占比降低的问题，所以，本申请实施例中，实现了手机全面屏的目的，提高了屏占比，参见图2所示，第一金属中框10的底边框靠近侧端盖203的位置开设电源接口206，即本实施例中，电源接口206靠近手机的底边缘设置，这样用户充电过程中，电源线位于手机的边缘处，对用户使用手机不易造成影响。
其中，为了确保电子设备的正常通信，电子设备中往往会设置多种天线。本申请实施例中，将第一金属中框10中内置天线的场景设置为场景一、将第一金属中框10和第二金属中框100中均设置内置天线的场景设置为场景二，将第一金属中框10和第二金属中框100中的至少一个上设置外接天线的场景设置为场景三。
下面，针对场景一、场景二和场景三，分别对折叠手机的结构进行描述。
场景一
参见图3所示，第一金属中框10中设有多个第一天线31，且多个第一天线31沿着第一金属中框10靠近侧端盖203的侧边间隔设置。例如，多个第一天线31位于侧端盖203的下方，多个第一天线31从侧端盖203设置摄像头204的一端到靠近电源接口206的一端依次间隔分布。需要说明的是，由于金属材料会对第一天线31产生干扰，所以为了防止侧端盖203对第一天线31产生的电磁波进行干扰，所以侧端盖203采用非金属材料制成，例如侧端盖203采用塑胶材料制成，这样多个第一天线31位于侧端盖203下方时侧端盖203对第一天线31产生的电磁波不会产生影响。
本申请实施例中，通过将多个第一天线31设置在第一金属中框10侧端且位于侧端盖203的下方，这样第一天线31、摄像头204、闪光灯205以及按钮202集中分布在侧端盖203处，一方面避免了第一天线31、摄像头204、散光灯以及按钮202对折叠手机显示区域的占用，这样折叠手机展开时可以实现全面屏。手机折叠时手机主屏也可以实现全面屏。另一方面，实现了折叠手机中天线的合理设置，从而解决现有技术中天线在折叠手机中不易布置的问题。
其中，本申请实施例中，多个第一天线31的工作频段可以为低频(700-960MHz)、中频(1.71-2.2GHz)和高频(2.3-2.7GHz)。其中，多个第一天线31可以为单频天线，例如其中一个第一天线31的工作频段为(700-960MHz)，另一个第一天线31的工作频段可以 为(1.71-2.2GHz)，其余一个第一天线31的工作频段可以为(2.3-2.7GHz)。或者，多个第一天线31中的其中部分第一天线31为多频天线，部分第一天线31为单频天线，例如，其中一个第一天线31为中高频天线(1.71-2.7GHz)，第一天线31的工作频段可以为(1.805-2.2GHz)和(2.3-2.69GHz)。其中，本申请实施例中，多个第一天线31的工作频段可以根据实际应用进行设计，本申请实施例对此不作限制。需要说明的是，多个第一天线31的工作频段可以覆盖中高低频段(例如，低频为700-960MHz，中频为1.71-2.2GHz，高频为2.3-2.7GHz)，这样电子设备可以正常通信。
示例性的，如图3所示，第一天线31的数量可以为11个。本申请实施例中，该些第一天线31可以为多输入-多输出(Multiple-Input Multiple-Output，简称：MIMO)天线、蓝牙天线、全球定位系统(Global Positioning System，GPS)天线、WIFI天线和长期演进(Long Term Evolution，LTE)天线等。本申请实施例中，MIMO天线的工作频段可以为(700-960MHz)、(1.7-2.2GHz)和(2.3-2.6GHz)，蓝牙天线的工作频段可以为(2400-2500MHz)，GPS天线的工作频段可以为(1575-1602MHz)，WIFI天线的工作频段可以为(2400-2500MHz)，其中LTE天线的工作频段可以为(824-960MHz)、(1710-2170MHz)和(2500-2690MHz)。
本申请实施例中，随着5G技术的发展，多个第一天线31中的部分第一天线31还可以为5G天线，例如5G WIFI天线或者5G MIMO天线。其中，当部分第一天线31为5G天线时，其中，5G天线的工作频段可以为(3300-3600MHZ)和(4800-5000MHz)。
其中，本申请实施例中，参见图4所示，多个第一天线31可以设置在承载件32上，承载件32与多个第一天线31组成一个整体结构安装在第一金属中框10，这样方便多个第一天线31的安装。应当理解的是，由于第一天线31为金属件，所以为了防止对第一天线31造成干扰，承载件32为非金属材料，例如，可以为塑料。本申请实施例中，多个第一天线31与承载件32可以为一体结构，例如多个第一天线31与承载件32可以通过纳米注塑工艺形成一整体结构。这样该整体结构中具有金属区域和非金属区域，其中，金属区域可以作为第一天线31，非金属区域可以作为承载件32。在安装第一天线31和承载件32时，可以在承载件32上开设安装孔进行固定，从而方便了第一天线31的安装。当然也可以通过其他方式安装，例如焊接等其他方式。
本申请实施例中，多个第一天线31和承载件32形成整体结构在第一金属中框10中安装时，第一天线31可以通过支撑件33撑起一定的高度，以确保第一天线31的下方具有一定的净空，净空可以为0.2-3mm，例如净空可以为0.5mm，也可以为1.5mm。其中，支撑件33将多个第一天线31和承载件32形成的整体结构进行支撑。其中，支撑件33可以为金属件，也可以为非金属件。其中，本申请实施例中，如图4所示，支撑件33、承载件32和多个第一天线31组成条状的天线组合件30，即支撑件33、承载件32和多个第一天线31可以为一个整体结构。
其中，支撑件33、承载件32和多个第一天线31可以通过纳米注塑工艺将三者形成整体的天线组合件30。这样安装时，通过支撑件33将天线组合件30支撑在第一金属中框10。需要说明的是，支撑件33为非金属材料时，此时可以将支撑件33的部分区域延伸形成支撑件33。当支撑件33为金属件时，此时支撑件33与第一天线31之间通过承载件32隔开，如图4所示，多个第一天线31和支撑件33之间通过承载件32隔开，当然支撑件 33、承载件32和多个第一天线31可以也可以通过其他方式安装，例如焊接等其他方式。
其中，本申请实施例中，天线组合件30与第一金属中框10之间可以设有印刷电路板20。天线组合件30通过支撑件33设在印刷电路板20上方，具体的，如图5和图6所示，支撑件33的两端分别设有第一安装部301和第二安装部302，第一安装部301和第二安装部302分别与印刷电路板20上的安装孔24和安装孔23通过紧固件(例如螺钉)进行固定。这样天线组合件30悬空安装在印刷电路板20上方。当支撑件33为金属件时，此时支撑件33的两端可以通过第一安装部301和第二安装部302与印刷电路板20接触实现接地。需要说明的是，天线组合件30与第一金属中框10之间设置有印刷电路板20，印刷电路板20的部分区域位于天线组合件30与第一金属中框10之间，印刷电路板20的其余部分还可以位于第一金属中框10的顶端和底端处，以供手机顶端和底端处的器件可以设置在印刷电路板20上。
其中，本申请实施例中，天线组合件30从第一金属中框10的顶端延伸到底端，如图5所示，天线组合件30与摄像头204和闪光灯205正对的区域分别开设可供闪光灯205和摄像头204装配的安装孔35和安装孔34，这样摄像头204和闪光灯205安装时，摄像头204和闪光灯205可以穿过安装孔34和安装孔35实现安装。
其中，本申请实施例中，第一天线31工作时，馈电点向第一天线31馈入高频电流。其中，馈电点可以设置在印刷电路板20上，第一天线31与馈电点之间电性相连，这样印刷电路板20通过馈电点向第一天线31馈入高频电流，高频电流在第一天线31上形成电磁波向外发射。本申请实施例中，如图5所示，第一天线31包括：第一馈点结构40a，第一馈点结构40a的一端与第一天线31电连接，例如可以通过铆接方式实现电连接，第一馈点结构40a的另一端与印刷电路板20上的馈电点电相连。其中，第一天线31与第一馈点结构40a的一端通过铆接连接时，实现了第一馈点结构40a与第一天线31之间具有较大的拉拔力，避免了在天线上焊接铜片或弹片时而导致铜片或弹片与天线之间的拉拔力较小的问题。由于第一馈点结构40a与第一天线31之间铆接连接，不存在焊接点，所以避免了由于焊接而导致天线上焊接点易受酸碱腐蚀的问题。
应当理解的是，第一馈点结构40a可以为金属件，例如，第一馈点结构40a的材料可以为铜，屈服强度为600MPa，硬度为280HV，磁导率<1.01。第一馈点结构40a可以为柱状结构，这样与现有技术中铜片或弹片馈点结构相比，第一馈点结构40a为柱状结构时，结构可靠性高。其中，第一馈点结构40a例如可以为铆钉。在其他示例中，第一馈点结构40a还可以为其他形状的结构。
其中，本申请实施例中，第一天线31的材料可以为铝(例如：为AL6013)。本申请实施例中，第一馈点结构40a与第一天线31可以直接铆接，这样不受材料之间焊接性能影响，第一天线31和第一馈点结构40a可选用多种材料。
其中，第一天线31与第一馈点结构40a铆接时，第一天线31与第一馈点结构40a铆接的区域厚度可以增厚，这样便于第一馈点结构40a与第一天线31实现铆接。需要说明的是，第一馈点结构40a和第一天线31的材料还可根据具体情况更换材料，但第一馈点结构40a的硬度可以高于第一天线31的硬度，以实现第一馈点结构40a压铆到第一天线31上。
其中，本申请实施例中，第一馈点结构40a与第一天线31铆接时，具体采用压铆的方式进行铆接，即将第一馈点结构40a通过压铆机压入第一天线31中。
其中，第一馈点结构40a与印刷电路板20上的馈电点之间的电连接可以通过多种方式实现。在一种可能的实现方式中，由于第一天线31位于印刷电路板20的上方，而印刷电路板20具有金属走线和金属器件，为了避免印刷电路板20上的金属走线对第一天线31的干扰，所以第一天线31与印刷电路板20之间具有一定间隔来确保第一天线31与印刷电路板20之间具有0.2-3mm的净空，本申请实施例中，第一天线31印刷电路板与印刷电路板20之间的最小高度H可以为0.2-3mm，例如第一天线31与印刷电路板20之间的最小高度H可以为0.5mm，也可以为1.5mm，这样可以确保第一天线31与印刷电路板20之间具有所需的净空，从而提高第一天线31的辐射效率。
参见图7所示，第一天线31朝向印刷电路板20的一面上开设装配部31a，该装配部31a可以为盲孔也可以为通孔，第一馈点结构40a的一端与第一天线31的装配部31a实现铆接。第一馈点结构40a的另一端朝向印刷电路板20。其中，印刷电路板20上可以设置有增高板21，该增高板21例如可以为印制电路板(Printed Circuit Board，PCB)，该增高板21与印刷电路板20上的馈电点电性相连，在增高板21上可以设有弹片22，弹片22通过增高板21与印刷电路板20上的馈电点电性相连。第一馈点结构40a的另一端抵接在弹片22，这样第一天线31通过第一馈点结构40a、弹片22和增高板21与印刷电路板20的馈电点导通。
本申请实施例中，弹片22可以为弹性器件，若弹片22与印刷电路板20上的馈电点连接，可能会出现弹片22与第一馈点结构40a无法抵接的情况，在印刷电路板20上设置增高板21，可以保证第一天线31与印刷电路板20之间存在净空的前提下实现弹片22与第一馈点结构40a的抵接。该增高板21可以起到将弹片22与第一馈点结构40a抵接的作用，也可以对第一天线31达到了匹配净空的作用。
其中，本申请实施例中，印刷电路板20上设置与馈电点电连接的增高板21，弹片22设在增高板21上，这样弹片22与印刷电路板20之间隔着增高板21，当印刷电路板20的馈电点周围走线较多时，通过增高板21使得弹片22与印刷电路板20的馈电点周围的走线之间间隔一定的距离，从而确保弹片22与印刷电路板20之间也具有一定的净空，所以，本申请实施例提供的增高板21还可以确保弹片22与主板20之间具有净空。
本申请实施例中，增高板21的高度可以为0.4-1mm，例如可以为0.5mm，也可以为0.8mm。
在另一种可能的实现方式中，如图8所示，第一馈点结构40a的另一端可以抵接在印刷电路板20上的馈电点区域。本申请实施例中，第一馈点结构40a的另一端可以直接抵接在印刷电路板20上的馈电点。
在另一种可能的实现方式中，如图9所示，印刷电路板20上设置有弹片22，弹片22与印刷电路板20上的馈电点电性相连，第一馈点结构40a的另一端抵接弹片22。本申请实施例中，第一天线31通过第一馈点结构40a和弹片22与印刷电路板20的馈电点实现导通。本申请实施例中，弹片22可为不锈钢片，通过印刷电路板20上的馈电点与弹片22连接，这样第一馈点结构40a与不锈钢的弹片22抵接，这样避免了第一馈点结构40a直接与馈电点抵接，随着馈电点处氧化或腐蚀，使得馈电点与第一馈点结构40a之间出现接触不良的问题。
其中，本申请实施例中，弹片22与印刷电路板20馈电点之间可以通过焊接、SMT贴 片或锁螺钉等固定方式进行连接。
本申请实施例中，第一天线31接地。如图10，第一天线31还包括接地部31b，接地部31b可以与印刷电路板20上的接地点电性相连。或者由于第一金属中框10与印刷电路板20的接地点相连，所以第一金属中框10为参考地，所以第一接地部31b可以直接与第一金属中框10相连实现接地。本申请实施例中，接地部31b可以为第一天线31朝向印刷电路板20或朝向第一金属中框10延伸形成的部分，或者接地部31b也可以为第一馈点结构40a，例如第一天线31包括两个第一馈点结构40a，其中一个第一馈点结构40a用于与印刷电路板20上的馈电点电性相连，另一个作为接地馈点进行接地，或者接地部31b也可以为铜片，铜片的一端与第一天线31通过焊接或紧固件相连，另一端接地。其中，接地部31b接地时，印刷电路板20上的接地点或第一金属中框10上可以焊接弹片，接地部31b与弹片抵接实现接地。
示例性的，如图11所示，第一馈点结构40a可以包括第一铆接部43和一端与第一铆接部43相连的第一抵接部45。其中，第一铆接部43用于与第一天线31的装配部31a之间进行铆接，第一抵接部45用于与印刷电路板20上的馈电点或印刷电路板20上的弹片22进行抵接。其中，为了使得第一馈点结构40a与第一天线31铆接更紧，具体的，如图11所示，第一铆接部43的外表面具有锯齿状的滚花，这样铆接时，第一馈点结构40a与第一天线31的装配部31a内壁之间的接触面增多，使得第一馈点结构40a与第一天线31之间铆接的更紧。
其中，本申请实施例中，为了增强第一抵接部45与弹片22之间的电连接性能，具体的，如图11所示，在第一抵接部45与弹片22抵接的一端上增加镀层46，该镀层46可以镀镍层(厚度为3～5μm)或镀金层(厚度≥0.25μm)，这样实现了第一馈点结构40a与弹片22之间良好的电性连接。
其中，本申请实施例中，为了在第一馈点结构40a与第一天线31铆接之前预先将第一馈点结构40a安装在第一天线31上，所以，如图11所示，第一馈点结构40a还包括第一定位部41，第一定位部41与第一铆接部43的一端相连，安装时，如图12所示，第一定位部41与第一天线31的装配部31a实现预定位，将第一馈点结构40a预先安装在装配部31a中，这样在横向(即X和Y向上)上对第一馈点结构40a在装配部31a内的位置进行限定，铆接时，第一馈点结构40a可以沿着第一定位部41向装配部31a中铆接，这样实现了第一馈点结构40a与第一天线31之间准确铆接的目的。
其中，本申请实施例中，为了防止铆接时第一馈点结构40a向第一天线31的装配部31a内伸入过多，具体的，第一馈点结构40a与第一天线31的装配部31a之间需进行限位。本申请实施例中，第一馈点结构40a与第一天线31的装配部31a之间具体可以通过两种方式实现限位，在一种可能的实现方式中，如图12所示，第一天线31的装配部31a为直孔，第一铆接部43与第一抵接部45之间具有限位部44，这样铆接时，如图13所示，当限位部44卡在装配部31a的进口边缘处，这样在纵向上对第一馈点结构40a进行限位，防止第一馈点结构40a的一端在装配部31a中深入过多。
在另一种可能的实现方式中，如图14所示，第一天线31的装配部31a为相通的两个腔体，且两腔体内壁之间形成限位台阶31c。铆接时，如图15所示，第一定位部41装入装配部31a的上腔体内，将第一铆接部43与装配部31a的下腔体内壁之间进行铆接，当第 一铆接部43移动到限位台阶31c处时，限位台阶31c对第一馈点结构40a进行阻挡，防止第一馈点结构40a向装配部31a中深入过多。
本申请实施例中，参见图15所示，第一定位部41与第一铆接部43之间具有宽度小于第一定位部41的第一配合部42，该第一配合部42使得第一定位部41、第一铆接部43以及装配部31a内壁之间形成预留空间，这样第一铆接部43与装配部31a内壁之间进行铆接时，在机械挤压过程中，装配部31a的部分内壁被第一铆接部43向上挤压到该预留空间中，这样当铆接完成时，此时挤压到该预留空间中的部分同时对第一定位部41起到阻挡作用，从而进一步地确保了第一馈点结构40a与第一天线31之间的可靠连接。
其中，本申请实施例中，第一馈点结构40a整体可以使用车削工艺加工，制作时，第一定位部41的直径可以为0.7-1.5mm，例如可以为0.83mm，对应的装配部31a的孔径可以为0.8-1.6mm，例如可以为0.9mm，第一铆接部43上的滚花的外径可以为0.9-1.7mm，例如可以为1.2mm，内径为0.3-0.6mm，例如可以为0.42mm，限位部44的直径可以为1.0-2.0mm，例如可以为1.5mm，第一抵接部45的直径可以小于或等于限位部44的直径，其中，本申请实施例中，第一馈点结构40a的尺寸包括但不限于上述数值。
场景二
本申请实施例中，第一金属中框10中设置第一天线31，如图16所示，在第二金属中框100中设置第二天线102，第一金属中框10与第二金属中框100之间通过转动件50(可以为转轴)相连，第一金属中框10和第二金属中框100分别位于转动件50两侧，其中，第一金属中框10通过与印刷电路板20的接地点相连实现接地。由于第二金属中框100通过转动件50与第一金属中框10相连，所以第二金属中框100通过转动件50也实现接地，即第一金属中框10和第二金属中框100在转动件50处共地，第一金属中框10和第二金属中框100形成完整的辐射参考地。其中，在第一金属中框10和第二金属中框100展开时，此时第一天线31与第二天线102之间由于距离较远，所以第一天线31和第二天线102之间干扰较小，相互影响较小，但是当第二金属中框100折叠到第一金属中框10上时，此时第一天线31与第二天线102之间由于距离较近，且尤其当第一天线31和第二天线102同频时(即第一天线31和第二天线102的工作频段相同，或者部分重叠，或者不重叠但两天线工作的频率范围间隔较小)，第一天线31和第二天线102之间存在信号干扰，对两个天线的性能影响较大。
本申请实施例中，第二天线102可以为第一天线31的寄生天线。当第二天线102为寄生天线时，此时，第二天线102可以不与馈电点相连，第二天线102不通过馈电点馈入高频电流，第一天线31耦合激励第二天线102。本申请实施例中，第二天线102包括回地点1021(具体见图20)。其中，第二天线102的回地点1021可以与第二金属中框100相连实现接地，或者第二天线102的回地点1021可以与第二金属中框100中设置的电路板103接地点相连实现接地，电路板103的接地点与第二金属中框100相连，最终实现第二天线102接地。
其中，本申请实施例中，如图16所示，第二天线102具体位于第二金属中框100的底端，且第二金属中框100可以包括三个边框，三个边框可以分别为底边框、顶边框和侧边框101，第二天线102可以为第二金属中框100中的底边框经过断缝形成，例如第二金 属中框100的部分底边框作为第二天线102。
其中，本申请实施例中，第一天线31和第二天线102的工作原理，具体为：当第一金属中框10和第二金属中框100展开时(即手机的副屏和主屏展开)，此时，第一天线31和第二天线102之间由于距离较远，第一天线31可能无法耦合激励第二天线102辐射，所以，第二天线102不工作，第一天线31为主天线工作在第一频段(例如可以为低频：700-960MHz，中频：1.71-2.2GHz，高频：2.3-2.7GHz)。
当第二金属中框100折叠到第二金属中框100上时(即手机的副屏和主屏折叠)，此时第一金属中框10和第二金属中框100之间的距离较近，第一天线31耦合激励第二天线102，第二天线102作为第一天线31的寄生天线工作。其中，第一天线31工作在第一频段，第二天线102工作在第二频段，第二天线102的辐射对第一天线31的辐射起到增强作用，从而提升了第一天线31的性能。
其中，本申请实施例中，当第一天线31为单频天线时，第一天线31的第一频段包括单频天线对应的频段，当第一天线31为多频天线时，第一天线31的第一频段包括多频天线对应的多个频段，第二天线102工作在第二频段时，第二频段可以为与第一频段相近的频段，或者第二频段可以为第一频段相差较大的频段。需要说明的是，当第一天线31的第一频段包括多个频段时，第二天线102的第二频段可以为与第一频段中其中一个频段相近或相差较大的频段，或者第二天线102的第二频段可以包括与第一频段中多个频段相近或相差较大的多个频段。
例如，第一天线31的第一频段可以为低频(700-960MHz)，第二天线102的第二频段可以为与低频频段相近的频段，例如第二频段可以为824-960MHz，或者第二天线102的工作频段可以为与低频工作频段相差较大的频段，例如可以为中频(1710-2200MHz)或高频(2.3-2.7GHz)。可以理解的，由于第一金属中框10中设置多个第一天线31，所以第二金属中框100与第一金属中框10折叠时，可以耦合激励第二天线102的为多个第一天线31中靠近第二天线102、能耦合激励第二天线102的其中一个或多个第一天线31。
其中，本申请实施例中，当第二金属中框100折叠到第一金属中框10上时，若第二金属中框100与第一金属中框10仍通过转动件50共地时，此时第二天线102接地的路径需绕到转动件50处与第一金属中框10共地，这样使得第二天线102与第一天线31的共地路径远，天线辐射时损耗较大，从而对辐射性能造成影响。
为此，本申请实施例中，第二金属中框100折叠到第一金属中框10上时，第一金属中框10与第二金属中框100就近共地。如图17所示，天线组合件30中的支撑件33通过第一安装部301和第二安装部302分别与印刷电路板20的安装孔24和安装孔23相连实现接地，同时印刷电路板20的接地点与第一金属中框10电连接，第一金属中框10作为第一天线31的地。本申请实施例中，如图17所示，卡扣201可以安装在支撑件33上，具体的，卡扣201与支撑件33之间可以设置弹片实现紧密接触，这样卡扣201通过支撑件33与第一天线31的地接通，此时，由于卡扣201与第二金属中框100的侧边框101卡合，所以，本申请实施例中，在第二金属中框100的侧边框101上设置与卡扣201卡合的连接结构40b，即本申请实施例中，连接结构40b与卡扣201实现卡合，其中，连接结构40b由于与第二金属中框100的侧边框101相连，所以连接结构40b通过侧边框101与第二金属中框100实现接地。
如图18所示，当第二金属中框100折叠到第一金属中框10上时，此时，卡扣201与连接结构40b卡合接触，第一金属中框10与第二金属中框100通过卡扣201与连接结构40b的接触实现就近共地，从而使得第二天线102的地与第一天线31的地较近。第一金属中框10和第二金属中框100通过转动件50、以及卡扣201和连接结构40b接触实现了双侧共地，这样可以满足主天线与寄生天线的地近的要求，也可以满足第一天线31和第二天线102的地多处完整的要求，最终达到提升天线性能的目的。
所以，本申请实施例中，通过连接结构40b与卡扣201的卡合，一方面实现了第二金属中框100和第二金属中框100折叠后不易自动展开的目的，另一方面实现了第一金属中框10与第二金属中框100就近共地，使得第一天线31和第二天线102的共地路径缩短，降低了辐射损耗，提升了天线性能。
其中，本申请实施例中，连接结构40b可以应用于活动状态下的动态部件的电连接场景中，本申请实施例提供的连接结构40b可以应用于更多的场景。
其中，本申请实施例中，如图19所示，为了对连接结构40b实现安装，具体的，第二金属中框100的侧边框101与卡扣201对应的位置开设凹槽1011，连接结构40b通过压铆方式压入侧边框101的凹槽1011中，实现连接结构40b与侧边框101的固定连接。本申请实施例中，通过压铆方式，使得连接结构40b与侧边框101之间的拉拔力增大，电连接可靠性高，不易被腐蚀，避免了连接结构40b与侧边框101之间焊接而导致侧边框101与馈点结构拉拔力小且易受腐蚀的问题。
其中，本申请实施例中，如图20所示，第二金属中框100内侧可以设置电路板103，电路板103的接地点与第二金属中框100电性连接。第二天线102的回地点1021与弹片104抵接，如图21所示，电路板103上的接地点电性连接弹片104，这样实现第二天线102的回地点1021与电路板103的接地点连接。
其中，本申请实施例中，如图22所示，连接结构40b可以包括第三铆接部402，第三铆接部402的一端端面上开设可供卡扣201卡入的内腔404，其中第三铆接部402用于与侧边框101进行压铆固定，内腔404用于卡扣201实现卡合。内腔404的深度和形状具体根据卡扣201及卡扣201形式进行调整。本申请实施例中，如图22所示，内腔404为长条状的凹槽1011，凹槽1011的槽深具体可以为0.2-1.0mm，例如可以为0.3mm，凹槽1011的壁厚可以为0.2-0.8mm，例如可以为0.4mm，且第三铆接部402的长可以为4-10mm，例如可以为5.85mm，宽可以为1.5-5mm，例如可以为1.85mm，需要说明的是，第三铆接部402和内腔404的尺寸包括但不限于为上述尺寸。
其中，由于卡扣201与内腔404的内壁接触要电性连接，所以，在内腔404的内壁(侧壁以及底壁)上设置耐磨镀层以保证电连接可靠性，其中，耐磨镀层可以为钯镍或者铑钌合金。卡扣201与内腔404的配合可以在10万次摩擦之后电阻小于1欧姆。
参见图22所示，为了确保卡扣201可以顺利卡入内腔404中，具体的，内腔404的开口处具有外缘403，且外缘403的端面为弧形面，这样便于卡扣201卡入内腔404中。
参见图22所示，连接结构40b还包括至少一个第二定位部401，其中，图22中示出两个第二定位部401，这样通过第二定位部401可以将连接结构40b安装在侧边框101的凹槽1011中。在横向上对连接结构40b起到定位作用，防止第二馈点在凹槽1011中前后左右晃动。需要说明的是，第二定位部401的数量包括但不限于为两个，还可以为多个。 其中，定位结构可以为类圆柱结构，直径可以为0.9mm，且两个定位结构之间间距可以为3.8mm。
图23和图24示出了连接结构40b与侧边框101之间的装配过程中，如图23所示，侧边框101的凹槽1011中具有分别与两个定位结构配合的装配孔1011a和装配孔1011b。两个装配孔1011a和装配孔1011b与凹槽1011内壁之间形成限位结构1011c，限位结构1011c对第三铆接部402起到纵向上的限位作用，防止第三铆接部402卡入凹槽1011中过多。
如图23所示，第二定位部401和第三铆接部402之间具有宽度小于定位结构的第二配合部405，第二配合部405的作用可以参见上述场景一中的第一配合部42的作用。
安装时，首先两个第二定位部401预先安装在装配孔1011a和装配孔1011b，实现预定位，接着，如图24所示，将第三铆接部402压铆到凹槽1011中，实现连接结构40b与侧边框101的固定连接。
其中，本申请实施例中，连接结构40b的材料可以为不锈钢(SUS316-0)，采用锻压和CNC(程序控制的自动化机床)工艺制成，且第一馈点结构40a磁导率<1.01，第二金属中框100和侧边框101的材料可以为铝(AL6013)，若侧边框101与连接结构40b之间采用焊接时，由于铝与不锈钢之间的焊接性能较差，所以两者的拉拔力较差，而本申请实施例中，侧边框101与连接结构40b铆接，这样避免了侧边框101与连接结构40b之间由于材料焊接性能差而导致拉拔力小的问题。
场景三
本申请实施例中，在第一金属中框10和第二金属中框100中的至少一个上设置外接天线300。如图25所示，以第二金属中框100为例进行说明，第二金属中框100可以包括三个边框，三个边框可以分别为侧边框101、顶边框和底边框，第二金属中框100中设置电路板20a，电路板20a具有馈电点，馈电点上连接有弹片22a。其中，外接天线300可以包括第二馈点结构40c。外接天线300通过第二馈点结构40c与弹片22a电连接。具体的，在侧边框101上开设通孔1012，第二馈点结构40c通过压铆方式压入通孔1012中，第二馈点结构40c的一端与弹片22a抵接，另一端与外接天线300可拆卸相连。具体的，外接天线300与第二馈点结构40c之间可以通过卡合或螺纹等方式可拆卸相连，这样需要外接天线300时，将外接天线300与第二馈点结构40c的一端相连，电路板20a通过馈电点向外接天线300馈入高频电流，高频电流在外接天线300上以电磁波方式向外辐射。
需要说明的是，第二金属边框100的侧边框101为金属边框时，第二馈点结构40c与侧边框101的通孔1012之间绝缘设置，例如，可以在第二馈点结构40c的外表面设置绝缘层，或者也可以在通孔1012的内壁上设置绝缘层，确保电路板20a上的馈电点馈入的高频电流经第二馈点结构40c传输到外接天线300，高频电流在外接天线300上形成向外发射的电磁波。
其中，在场景二中，第一金属中框10和第二金属中框100展开时，第一天线31工作，第二天线102不工作，本申请实施例中，外接天线300通过第二馈点结构40c可拆卸连接在第二金属中框100，第一金属中框10和第二金属中框100展开后，第一金属中框10中的第一天线31工作，第二金属中框100上的第二天线102不工作，第二金属中框100上 的外接天线300可以工作，这样确保了两个可折叠的金属中框展开时各自的天线可以工作。
在一种可能的实现方式中，当内置天线(例如第一天线31和第二天线102)可以满足正常通信的频段时，可以将外接天线300与第二馈点结构40c断开。当内置天线无法满足正常通信时，可以通过第二馈点结构40c连接外接天线300，通过外接天线300实现正常通信，或者，在内置天线满足正常通信的要求时，外接天线300也可以仍然与第二馈点结构40c相连。本申请实施例中，第二馈点结构40c作为外接天线300的馈点，通过外接天线300与第二馈点结构40c的断开和连接实现电子设备上的内置天线和外接天线300的切换。
其中，图26和图27示出了第二馈点结构40c、外接天线300以及与电路板103之间的装配结构，参见图26所示，第二馈点结构40c可以包括第二铆接部402c，第二铆接部402c的一端具有卡槽404c，外接天线300上具有与卡槽404c卡合的卡合部310，如图27所示，外接天线300通过卡合部310与卡槽404c卡合连接在第二馈点结构40c上，需要断开时，将卡合部310从卡槽404c中拔出即可实现外接天线300与第二馈点结构40c的断开。
其中，参见如图26和图27所示，第二馈点结构40c还包括第二抵接部405c，第二抵接部405c的一端与第二铆接部402c相连，另一端抵接到弹片22a上。这样可以实现外接天线300与电路板20a的馈电点的电连接。本申请实施例中，第二馈点结构40c与外接天线300的断开和连接，使得第二馈点结构40c不限于应用于固定连接的场景中，第二馈点结构40c和场景二中的连接结构40b均可应用于可活动电连接的场景，相比于焊接馈点结构，本申请实施例提供的铆接的馈点结构应用的场景更多，即可应用于固定连接的场景，也可以应用于活动连接的场景，这样满足5G等新技术规模化应用时馈点结构所应对的场景增多的要求。
其中，本申请实施例中，需要说明的是，外接天线300可以但不限于在第一金属中框10和第二金手中框100上进行设置，外接天线300通过第二馈点结构40c还可以设置在非折叠手机的金属中框的侧边框上。
在本申请实施例的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应作广义理解，例如，可以是固定连接，也可以是通过中间媒介间接相连，可以是两个元件内部的连通或者两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请实施例中的具体含义。
本申请实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)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。
最后应说明的是：以上各实施例仅用以说明本申请实施例的技术方案，而非对其限制；尽管参照前述各实施例对本申请实施例进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请实施例各实施例技术方案的范围。
