Description

手持设备电池及手持设备
技术领域
本发明涉及增强型近距离无线通信手持设备技术领域， 尤其涉及一种手 持设备电池及及手持设备。
背景技术
近年， 具有 NFC ( Near Field Communication, 近距无线通信）功能的手 持设备逐渐走入市场。 NFC釆用 13.56MHz的工作频段， 它可以实现非接触 式 IC卡模拟、读卡器、点对点数据交换的功能，数据传输率可以达到 424kbps。
在 NFC方案的基础上， 又衍生出来了 eNFC方案， eNFC方案是 NFC方 案的改进， eNFC方案将需要保密和鉴权的信息放到 SIM ( Subscriber Identity Model, 客户识别模块）卡中， 通过 SIM卡中的应用程序完成各种应用。
由于实现 NFC功能需要使用一个面积较大的绕线天线， 而一般手持设备 内部由于空间所限 ,很难把如此大面积天线做到内部的 PCB板（ Printed circuit board, 印刷电路板） 中， 所以目前多数厂家一般把天线做成 FPC (柔性 PCB 板） ， 贴到外壳内壁上。 外壳组装上后， 作为天线的 FPC通过焊盘和主板上 NFC天线连接器紧密压接。
上述方法带来的问题是：首先由于不同的手持设备由于外形设计的不同， 外壳也不尽相同，这样就要针对不同的外壳设计不同的 NFC天线和天线连接 器； 并且由于针对每款专用的 NFC天线， 都要调试对应的天线匹配电路， 这 样不但增加了成本， 增大的研发的难度， 还会大大延长研发周期， 推迟产品 上市的时间； 其次就是外壳要给 NFC天线避让出一定厚度， 就可能会造成外 壳过薄， 跌落时会引起裂缝； 再次也会给生产组装带来一定的困难。
发明内容
鉴于上述的分析， 本发明旨在提供一种手持设备电池及及手持设备， 用 以解决现有技术中存在的 NFC天线设计难度大、 成本高等问题。
本发明的目的主要是通过以下技术方案实现的：
本发明提供了一种手持设备电池， 其包括： 电池本体、 NFC天线、 铁氧 体和标签纸， 其中， 铁氧体设置于电池本体上， NFC天线设置于铁氧体上， 标签纸设置于 NFC天线上。
优选地， 电池本体的一侧面设置有电池金手指， NFC天线包括 NFC金手 指， 且 NFC金手指设置于电池金手指所在的侧面上。
优选地， 标签纸覆盖电池本体、 铁氧体和 NFC天线， 且 NFC金手指和 电池金手指棵露于标签纸外。
本发明还提供了一种手持设备， 其包括： 手持设备电池和 NFC天线连接 器， 其中， 手持设备电池包括电池本体、 NFC天线、 铁氧体和标签纸， 铁氧 体设置于电池本体上， NFC天线设置于铁氧体上，标签纸设置于 NFC天线上， NFC天线包括 NFC金手指； NFC金手指与 NFC天线连接器电连接。
优选地， 电池本体的一侧面设置有电池金手指， 且 NFC金手指设置于 电池金手指所在的侧面上。
优选地， 标签纸覆盖电池本体、 铁氧体和 NFC天线， 且 NFC金手指和 电池金手指棵露于标签纸外。
优选地， NFC天线连接器包括 NFC弹簧触片， 该弹簧触片与 NFC金手 指接触。
本发明有益效果如下：
本发明不但大大降低了 NFC天线的设计难度，缩短研发周期，降低成本， 而且还可以实现 NFC天线的模块化设计。
本发明的其他特征和优点将在随后的说明书中阐述， 并且， 部分的从说 明书中变得显而易见， 或者通过实施本发明而了解。 本发明的目的和其他优 点可通过在所写的说明书、 权利要求书、 以及附图中所特别指出的结构来实 现和获得。 附图概述
图 1为本发明实施例所述手持设备电池的结构示意图；
图 2为本发明实施例手持设备电池的外型示意图。
本发明的较佳实施方式
本发明的目的在于提供一种手持设备电池及手持设备，通过把 NFC天线 内嵌入电池内部， 不但减少了 NFC手持设备整机设计复杂度， 增强 NFC天 线的通用性， 提高设计的灵活性， 还能够降低成本。
下面结合附图来具体描述本发明的优选实施例， 其中， 附图构成本申请 一部分， 并与本发明的实施例一起用于阐释本发明的原理。 为了清楚和简化 目的， 当其可能使本发明的主题模糊不清时， 将省略本文所描述的器件中已 知功能和结构的详细具体说明。
首先结合附图 1和附图 2对本发明实施例所述手持设备电池进行详细说 明。
如图 1所述， 图 1为本发明实施例所述手持设备电池的结构示意图， 具 体可以包括： 电池本体、 NFC天线、 铁氧体和标签纸， 铁氧体设置于电池本 体上表面、 NFC天线设置于铁氧体上、 标签纸设置于 NFC天线上， NFC天 线包括 NFC金手指。
其中， NFC天线在尺寸和形状上与电池本体相当， 即二者在尺寸和形状 上相等， 或者 NFC天线的尺寸和形状略小于电池本体； 电池本体金手指所在 侧面的另一侧预留有 NFC天线的焊盘空间， NFC天线的三个金手指通过背胶 粘贴到电池金手指所在侧面预留的焊盘空间处， 并且 NFC 天线的金手指与 NFC天线连接器电连接。
需要注意的是，在向电池本体上贴标签时注意露出电池和 NFC天线的金 手指， 即标签纸覆盖电池本体、 铁氧体和 NFC天线， 且 NFC金手指和电池 金手指棵露于标签纸外。
虽然手持设备呈现出各种各样的外形， 但是属于同一家公司的产品所使 用的电池大多是通用的， 就是几款电池用于很多款机型。 本发明实施例所述 的手持设备电池不但增强了电池和电池连接器的通用性， 也避免了为每一款 机型设计一款电池的成本。
并且由于手持设备电池外型和电芯的限制， 一般都做成扁平的立方体， 目前经常见到的扁平电池的表面积，对于 NFC天线已经足够大。 所以把 NFC 天线嵌入到电池中去， 不但可行， 还可以降低 NFC天线的设计难度。
如图 2所示， 图 2为本发明实施例手持设备电池的外型示意图， 通过图 2 可以看出 NFC 天线的金手指和电池金手指位于手持设备电池的同一侧面 上， NFC天线内嵌到铁氧体与标签纸中间。 实际应用时， 要求 NFC天线的三 根金手指与手持设备中设置的 NFC天线连接器露出的三个弹簧接触片在位置 ——对应。 使用时， 将手持设备电池嵌入到手机中， NFC天线的三根金手指 与手持设备中设置的 NFC天线连接器中的三个弹簧接触片自然压紧即可。
本发明实施例所述手持设备至少包括： 手持设备电池本体、 NFC天线、 铁氧体和标签纸， 铁氧体设置于电池本体上、 NFC天线设置于铁氧体上、 标 签纸设置于 NFC天线上， NFC天线包括 NFC金手指， 。
电池金手指所在侧面的另一侧预留有 NFC天线的焊盘空间， NFC天线的 金手指粘贴到电池金手指所在侧面预留的焊盘空间处，并且 NFC天线的金手 指与 NFC天线连接器的弹簧触片在位置上相对应， 即 NFC天线的三根金手 指与手持设备中的 NFC天线连接器露出的三个弹簧接触片在位置——对应。 使用时， 将手持设备电池嵌入到手持设备中， NFC天线的三根金手指与手持 设备中的 NFC天线连接器中伸出的三个弹簧接触片自然压紧即可。
综上所述， 本发明实施例提供了一种手持设备电池及手持设备， 通过把 NFC天线内嵌入电池内部， 降低了 NFC天线的设计难度， 缩短研发周期， 降 低成本， 而且还可以实现 NFC天线的模块化设计； 并且， 釆用本发明实施例 所述手持设备电池的 NFC手持设备不用再考虑外壳厚薄的问题，生产组装简 单。
以上所述， 仅为本发明较佳的具体实施方式， 但本发明的保护范围并不 局限于此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可 轻易想到的变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明 的保护范围应该以权利要求书的保护范围为准。
工业实用性
本发明不但大大降低了 NFC天线的设计难度，缩短研发周期，降低成本, 而且还可以实现 NFC天线的模块化设计。
