Description

无线通信装置
技术领域
本发明涉及一种无线通信装置,尤其涉及一种体积小的手表式无线通信装置。
背景技术
随着无线通信技术的快速发展,出现了集合手机与手表的功能于一体的手表式无线通信装置,这种装置可以如手表般方便的携带于用户的手腕上,还可以实现手机的语音通话、收发邮件及信息等通信功能。实现这些通信功能大多需要天线,然而手表式无线通信装置自身的体积很小,如何在有限的空间设计出手表式无线通信装置的天线成为迫切需要解决的问题。
发明内容
针对上述问题,有必要提供一种体积小的无线通信装置。
一种无线通信装置,包括接口,该接口包括连接片,该接口插接于外部电源或设备时,通过连接片为该无线通信装置充电,该接口未连接于外部电源或设备时,该连接片馈入信号以作为收发信号的天线。
本发明将无线通信装置的连接片作为天线,可有效减小无线通信装置的空间。
附图说明
图1为本发明较佳实施方式的无线通信装置的结构示意图。
图2为图1所示无线通信装置的结构分解示意图。
图3为图1所示无线通信装置的结构的部分示意图。
图4为图1所示无线通信装置的结构的部分分解示意图。
图5为本发明的无线通信装置的天线的回波损耗示意图。
主要元件符号说明
如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
请参阅图1至图2,本发明较佳实施方式的无线通信装置100包括主体10、可拆卸手带20及连接部30。该主体10及可拆卸手带20均呈C形或大致C形,该连接部30用于连接主体10及可拆卸手带20,使得该主体10、可拆卸手带20及连接部30共同形成一环形空间以容置用户的手腕。
请一并参阅图3及图4,该主体10包括接口11及电路板13。该主体10还包括用于实现该无线通信装置100的主要功能的显示屏或触控屏、按键、CPU芯片、蓝牙模块等电子元件。该接口11包括外壳111及连接片113,在本实施方式中,该接口11为通用串行总线(Universal Serial BUS, USB)接口。该无线通信装置100通过该接口11连接到外部电源或设备以充电或传输信息。
该外壳111用于插接外部电源或设备。
该连接片113包括正极连接片115及负极连接片116。在本实施方式中,正极连接片115与负极连接片116的形状及大小一样。该负极连接片116包括依次连接的第一辐射段1161、第二辐射段1162、第三辐射段1163、第四辐射段1164及第五辐射段1165。该第一辐射段1161与电路板13连接。该第二辐射段1162与第一辐射段1161在同一平面上,且该第二辐射段1162的宽度小于第一辐射段1161。该第三辐射段1163大致呈曲折的斜坡状,其与第二辐射段1162的夹角为锐角。该第四辐射段1164由第三辐射段1163朝靠近且垂直或大约垂直于第一辐射段1161的方向延伸而成。该第五辐射段1165一端垂直连接于第四辐射段1164,另一端设置于外壳111上。在本实施例中,该连接片113为金属片。可以理解,该连接片113也可以为软性电路板(Flexible Print Circuit,FPC)。
该电路板13包括正端131及负端133。该正端131与正极连接片115电性连接,该负端133与负极连接片116电性连接。该负端133包括第一结合段1331、第二结合段1332及第三结合段1333。该第一结合段1331与第三结合段1333平行设置,该第二结合段1332与负极连接片116的第一辐射段1161贴合接触。该第一结合段1331设置有一信号馈入点40,该信号馈入点40通过弹片、微带线或者同轴光缆等连接至系统馈入源(图未示),该第三结合段1333接地处理。
当该外壳111没有连接外部电源或设备时,该负极连接片116作为收发信号的天线。信号馈入点40向负端133馈入信号,该负极连接片116与负端133连接,故该信号馈入负极连接片116,使负极连接片116产生谐振,从而将该负极连接片116作为天线。在本实施方式中,该负极连接片116作为蓝牙天线(2.4~2.484GHz),可使无线通信装置100与其他蓝牙设备传输各种信息,比如:时间、心跳、行事历提醒等。请参阅图5,所示为本发明较佳实施方式的无线通信装置100的天线的回波损耗(Return Loss,RL)测量结果示意图。由图可以看出,该无线通信装置100于蓝牙工作频段下满足天线工作设计要求。
当该接口11连接于外部电源或设备时,该接口11通过连接片113连接外部电源或设备的正负极,以对该无线通信装置100充电。同时,该接口11还包括可以与外部设备电性连接以传输数据的数据端子(图未示),当接口11连接于外部设备时,该无线通信装置100可以通过数据端子与外部设备传输信息。此时,信号馈入点40受无线通信装置100的CPU的控制,停止向负端133馈入信号。
可以理解,通过在信号馈入点40增加匹配电路或改变电路板13的负端133的结构可以使该负极连接片116工作于其他频段,比如全球定位系统(Global Positioning System,GPS)频段、第三代移动通信(3rd-generation,3G)频段等。
本发明将无线通信装置100的接口11的负极连接片116当作天线,可有效节省无线通信装置100的空间。
另外,本领域技术人员还可在本发明权利要求公开的范围和精神内做其他形式和细节上的各种修改、添加和替换。当然,这些依据本发明精神所做的各种修改、添加和替换等变化,都应包含在本发明所要求保护的范围之内。
