背景技术
随着智能手表的兴起，智能手表的功能也越来越多。现有的智能手表，其大部分功能均需要通过接收外界的信号实现(如打电话、付款等)，因此，智能手表上需要设置天线以传输信号。
但由于智能手表的尺寸较小，内部集成空间相对于其他设备更加局限，集成难度更大。因此如何在智能手表上设计天线成为业内人士研究的问题。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术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发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例提供的智能手表的结构示意图。
附图标记：
1、金属表壳；2、电路板；3、接地部件；4、馈电部件；5、缝隙；6、显示屏；7、表盖；8、表带；9、表耳。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
为了实现上述目的，本发明实施例提供了一种智能手表，图1为本发明实施例提供的智能手表的结构示意图，该智能手表包括金属表壳1、电路板2、接地部件3和馈电部件4，电路板2位于金属表壳1内，接地部件3与电路板2和金属表壳1两者电连接，馈电部件4与电路板2和金属表壳1两者电连接，金属表壳1上开有缝隙5。
具体地，电路板2可以为现有的智能手表处理数据的主板，其可以实现通话功能、付款功能等，当然电路板2还可以实现其他功能，本发明对此不做限定。金属表壳1的材质可以为不锈钢，为了实现良好的导电功能，金属表壳1的材质优选为铝。接地部件3和馈电部件4均具有导电功能，接地部件3与电路板2和金属表壳1电连接，馈电部件4与电路板2和 金属表壳1电连接，以使金属表壳1与电路板2电连接，金属表壳1上开有缝隙5，以使接地部件3、馈电部件4和带有缝隙5的金属表壳1共同构成一个缝隙天线，可实现信号的传输。
本发明实施例提供的智能手表，利用原有的智能手表的金属表壳完成了天线设计，本申请简单易行、便于实施，同时节省了单独制造天线所需的材料。也节约了智能手表内部的硬件集成空间，解决了单独天线在智能手表中缺少集成空间的问题。
进一步地，电路板2上设有接地片和信号传输线，接地部件3与接地片电连接，可增加信号的稳定性；馈电部件4与信号传输线电连接，以实现接收和发送信号。
可选地，接地部件3和馈电部件4还可以为普通的金属片，通过焊接的方式，将金属片焊接在金属表壳1内壁上。可选地，接地部件3可以为弹片，馈电部件4可以为弹片。本实施例中，弹片为现有的用于机械或电学领域的具有导电性的弹性金属片，可抵接在金属表壳1的内壁上。
金属表壳1上缝隙5的位置可以随意设定，但需要说明的是，金属表壳1上缝隙5的位置，以及接地部件3和馈电部件4与金属表壳1的接触点的位置共同确定了天线工作的频率，因此可通过改变缝隙5的位置、接地部件3或馈电部件4与金属表壳1接触点的位置得到特定的频率。
为了得到特定的频率(如中国使用的无线信号的频率、美国使用的无线信号的频率等)，在实际制作智能手表时，可通过现有的信号仿真技术模拟信号的信道，从而确定缝隙5、接地部件3和馈电部件4与金属表壳1的接触点的位置。
进一步地，智能手表还包括显示屏6，显示屏6固定安装在金属表壳1的外端面上并与电路板2电连接。本实施例中，显示屏6可以为现有任意的具有显示文字、图像等功能的显示屏，在此不做具体限定。
可选地，表壳的外端面上设置有安装槽，显示屏6嵌装于安装槽内，使智能手表的外形更加美观，并且节省了空间；显示屏6还可以通过螺钉固定安装在表壳的外端面上，增加显示屏的固定效果。
进一步地，智能手表还包括表盖7(表盖7位于图1中的金属表壳1的后端面上)，金属表壳1上设置有插装孔，表盖7固定安装在金属表壳1上，以封堵插装孔。本实施例中，插装孔可用于智能手表的维修；表盖7可起到保护电路板2的作用。举例而言，当智能手表的电路板2出现故障后，可拆下表盖7，通过插装孔将电路板2从金属表壳1内取出，对电路板2进行维修。
进一步地，智能手表还包括表带8，表带8与金属表壳1两侧固定设置的表耳9可拆卸连接。具体地，每个表耳9的两侧均设置有安装孔，表带8的两侧均设置有与安装孔匹配的插入杆，表带8为弹性表带。举例而言，当装配表带8时，可将表带8挤压弯曲，使表带8两侧的插入杆之间的距离缩短，然后，将表带8两侧的插入杆对准表耳9两侧的安装孔并释放表带8，表带8两侧的插入杆均插入安装孔内，完成表带8的安装；当拆卸表带8时，挤压表带8，当表带8两侧的插入杆从表耳9两侧的安装孔中抽出后，退出表带8，完成表带8的拆卸。
优选地，为了避免外界的粉尘或水汽从缝隙5中进入金属表壳1内，金属表壳1上的缝隙5内可填充有绝缘体。同时，在绝缘体的表明面喷上一层与金属表壳1相同颜色的漆，既进一步避免了外界的粉尘或水汽的进入，同时用户在佩戴时，无法察觉缝隙5的存在，可使智能手表更加美观。优选地，绝缘体可以为塑料。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
本说明书中的各个实施例均采用相关的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于系统实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
以上所述仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内所作的任何修改、等同替换、改进等，均包含在本发明的保护范围内。
