Description

一种支持NFC功能和指纹识别功能的装置和终端 技术领域
本文涉及终端的NFC功能和指纹识别功能技术领域，特别是涉及一种支持NFC功能和指纹识别功能的装置和终端。
背景技术
随着技术的发展，终端中配置了指纹识别功能，在现有需求基础上，如何在终端中增加设置近场通信(NFC，Near Field Communication)功能，存在不同的实现方法：
在终端(例如：手机)后壳为非金属的情况下，将具备NFC功能的NFC天线设置在手机后壳上或者贴在电池上；在手机后壳为部分金属部分非金属的情况下，将NFC天线贴在后壳的非金属部分；在手机后壳为全金属的情况下，NFC天线利用后置摄像头的开孔，NFC天线中信号线设置在后置摄像头周围。(如HTC M8)。
在终端后壳为全金属的情况下，如果利用后置摄像头在后壳上的开孔(如HTC M8)对整机的布局比较限制。后置摄像头需要远离手机其他天线位置，一般需要放在后壳中间位置。但为了便于用户拍摄，很多终端的后置摄像头都设置在后壳的一个角落，而这个角落需要放置其他的天线，无法再放置NFC天线。
因此，对于全金属后壳的终端设备，放置NFC天线比较困难。

本发明的较佳实施方式
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
为了解决相关技术中全金属后壳的终端设备上放置NFC天线比较困难的问题，本发明提供了一种支持NFC功能和指纹识别功能的装置和终端，以下结合附图以及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
对于全金属后壳的终端设备，NFC天线的实现比较困难，如果要实现，需要在全金属后壳开孔，但造型方面希望后壳保证完整的全金属，不希望开孔。而大部分终端设备自身带有指纹识别功能，即在全金属后壳上开孔以设置指纹识别模块。基于此，可以将NFC天线需要的开孔和指纹识别模块在后壳上的开孔共用。把NFC天线和指纹识别模块做成一体，以解决相关技术中全金属后壳的终端设备上放置NFC天线比较困难的问题。下面通过实施例对本发明的技术方案进行详细介绍。
本实施例提供了一种支持NFC功能和指纹识别功能的装置，图1是根据本发明实施例的支持NFC功能和指纹识别功能的装置的结构示意图，如图1所示，该装置包括：NFC天线11和指纹识别模块12，本实施例将NFC天线 11和指纹识别模块12进行空间复用，指纹识别模块12嵌于NFC天线11的中间无线圈走线部位；指纹识别模块12的大小、外形与终端后壳开孔的大小、外形一致，二者相互吻合，将所述装置与所述终端组装后，指纹识别模块12的上表面(或者称为盖板)与所述终端的全金属后壳的外表面平齐，即处于同一水平面上。
NFC天线11包括：柔性电路板FPC基材、信号线和铁氧体；其中，指纹识别模块12与NFC天线11共用上述FPC基材，NFC天线的信号线布置在上述FPC基材上。
图2所示的是根据本发明实施例的移动终端中NFC天线的爆炸图，如图2所示，21表示NFC天线的铁氧体，22表示NFC天线的FPC基材，铁氧体21贴合在FPC基材22的反面，该反面是指FPC基材靠近终端内电路板的一面，且该铁氧体21的位置、大小与FPC基材22上布置的NFC天线11的信号线的位置、大小对应一致。
图3所示的是根据本发明实施例的移动终端中NFC天线的走线图，如图3所示，31表示NFC天线的信号线，采用双面FPC实现，NFC天线的信号线可以在FPC基材的正反两面走线。
在将NFC天线11和指纹识别模块12进行空间复用之后，如何实现信号收发，可以至少通过以下方式实现：
(1)NFC天线11的信号线与指纹识别模块12的信号线，均通过终端内主板上的弹片，与终端主板上的信号线连接。
(2)NFC天线11的信号线与指纹识别模块12的信号线，均通过连接器与主板上的信号线连接。图4所示的是支持NFC功能和指纹识别功能的装置的优选结构示意图，如图4所示，连接器13，与NFC天线11相连。
图5所示的是根据本发明实施例的移动终端装配示意图，如图5所示，13表示连接器，54表示终端后壳。连接器与终端内主板连接，该连接器所起的作用与终端内主板上的弹片作用是一样的。其中，NFC天线11和指纹识别模块12组成的装置贴在手机终端后壳54上，NFC天线11正面朝向手机终端后壳54的外侧。指纹识别模块12位于NFC天线11中间无线圈走线位置。 指纹识别模块12的大小、外形与终端后壳54开孔的大小、外形一致，并且安装时对准手机终端后壳54开孔安装，安装后指纹识别模块12的上表面与手机后壳54外表面平齐。
本实施例介绍的支持NFC功能和指纹识别功能的装置，可以通过贴合的方式固定在终端后壳，或者终端后壳下方的屏蔽罩，或者终端后壳下方的电池。
本发明技术方案还提供了一种终端，包括上述实施例介绍的支持NFC功能和指纹识别功能的装置。该终端可以是手机终端、pad、笔记本等无线终端。
在阅读并理解了附图和详细描述后，可以明白其他方面。
对于本发明技术方案，不仅限于应用在全金属终端后壳上，还可以应用在非金属材质的终端后壳上。另外，NFC天线和指纹识别模块不仅可以放在终端后壳上(包括直接贴在终端后壳上、贴在终端后壳下方的屏蔽罩上或者贴在终端后壳下方的电池上)，同时可以放在终端前面板上，如终端正面按键处。
从以上的描述可知，在本发明中将NFC天线和指纹识别做成一个模块，在不影响后壳全金属终端外观造型的前提下，解决了NFC天线实现的难题。从而减少终端后壳上的开孔，保证终端外观造型的美观。另外，还可以节约物料成本，减少组装时间，节约人工成本。
尽管为示例目的，已经公开了本发明的优选实施例，本领域的技术人员将意识到各种改进、增加和取代也是可能的，因此，本发明的范围应当不限于上述实施例。
工业实用性
在本发明的技术方案中，为了保证终端后壳全金属的完整性，NFC天线和指纹识别模块做成一体，指纹识别模块放置于NFC天线中间无线圈走线处，从而节省指纹识别模块的空间，满足了终端设置增设NFC天线的性能要求，同时满足了终端造型美观的要求。因此本发明具有很强的工业实用性。
