现有很多终端设备中搭载有NFC装置(或称为NFC模块)，通常将NFC的驱动电路板和NFC天线线圈做成一体化的片状。因为NFC的驱动电路需要设置在特定的位置以保持与终端设备的主电路板的连接，所以NFC装置通常固定于终端内侧，例如装配在手机或者移动电源的后盖内侧，并且尽可能靠近终端设备的背部。
但是，当终端设备的后盖材质为金属时，或者在终端设备后盖外侧加装了如摄像头或者充电设备等其他扩展功能模块时，装配在终端后盖内侧的NFC装置将不能正常通信。
发明内容
本发明实施例提出了一种近距离无线通信NFC装置，用以解决金属材质后盖或者终端附加的其他扩展功能模块影响终端NFC装置通信的问题。

具体实施方式
为了使本发明的技术方案及优点更加清楚明白，以下结合附图对本发明的示例性实施例进行进一步详细的说明，显然，所描述的实施例仅是本发明的一部分实施例，而不是所有实施例的穷举。并且在不冲突的情况下，本说明中的实施例及实施例中的特征可以互相结合。
发明人在发明过程中注意到：当终端设备的后盖材质为金属时，或者在终端设备后盖外侧加装了如摄像头或者充电设备等其他扩展功能模块时，装配在终端后盖内侧的NFC装置将不能正常通信。
针对上述不足，本发明提供了一种NFC装置，将NFC装置的NFC驱动电 路与NFC天线分开设置，使终端内部线路布局可以更灵活，并且使NFC天线能够在需要时滑动至终端外侧，避免终端壳体或终端附加的其他扩展功能模块对终端NFC装置通信的影响。
为了便于本发明的实施，下面以实例进行说明。

驱动电路板102安装有NFC天线的驱动电路，其通过螺钉与手机的机体固定连接，也即与手机的后壳层固定连接。在驱动电路板102与手机的后壳层间形成夹缝，在夹缝中NFC板101可以滑动出终端设备外，或者收置于终端设备内。在驱动电路板102的边缘朝向NFC板101设置有两个导电弹片103，所述导电弹片103与驱动电路板上的NFC驱动电路电联通，并且其能够分别抵接在NFC板101的两个金属条106上。所述金属条106与NFC板101上铺设的NFC 天线104电联通，基于导电弹片103和金属条106的连接关系，所述NFC驱动电路能够与NFC天线104电联通。为进一步确保NFC板101能够在夹槽中可靠滑动，在NFC板101的两侧设置有两条通槽，在壳体上分别设置有两个与通槽配合的凸起105，当NFC板在夹槽中滑动时，所述凸起105能够沿通槽滑动，并当NFC板滑动出终端设备时，限制其可滑动的最大位置，避免其滑脱。
图2示出了本发明实施例二中NFC装置处于工作状态时的结构示意图。终端设备200中设置了前述NFC装置100，图2中示出了所述NFC装置中的NFC板被拉出终端设备时的状态
图3示出了本发明实施例二中NFC装置处于非工作状态时的结构示意图。终端设备200包括前壳层201、中框层202和后壳层203，所述NFC装置100的NFC板101可以由终端设备200的中框层202抽出，驱动电路板102固定安装在前壳层201，进而与所述后壳层203固定连接，若中框层202相对较厚，所述驱动电路板102也可能固定安装在中框层202。(或者也可反向安装，即驱动电路板102安装在中框层202或后壳层203，NFC板101位于驱动电路板102和前壳层201之间。)
本实施例中将NFC装置100的NFC驱动电路与NFC天线104分开设置，使终端内部线路布局可以更灵活，并且使NFC天线104能够在需要时滑动至终端外侧，避免终端壳体或终端附加的其他扩展功能模块对终端NFC装置110通信的影响。并且本实施例中在NFC板101的两侧分别开设了通槽，其与后壳层203的凸起相配合能够使NFC板101相对于终端设备200的滑动更加可靠，也使导电弹片103与金属条106的电联通更加可靠，并且限制了NFC板不会完全滑出终端设备外。
实施例三：
基于同一发明构思，本发明实施例中还提供了近距离无线通信NFC终端设备，由于其原理与近距离无线通信NFC装置相似，因此其实施可以参见装置的实施，重复之处不再赘述。所述终端设备包括：壳体和上述任一种实施方式的近距离无线通信NFC装置。
可以理解，本领域技术人员还可于本发明精神内做其它变化，只要其不偏离本发明的技术效果均可。这些依据本发明精神所做的变化，都应包含在本发明所要求保护的范围之内。
