Description

智能移动终端USB TYPE-C接口系统
相关申请的交叉参考
本申请要求于2016年3月29日提交中国专利局、申请号为201610188884.7、发明名称为“智能移动终端USB TYPE-C接口系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及USB TYPE-C接口应用技术领域，尤其涉及一种智能移动终端USB TYPE-C接口系统。
背景技术
当前，随着智能手机和平板电脑的性能越来越强大以及屏幕越来越大，其功能性也逐渐可以像笔记本电脑一样使用，鼠标、键盘和U盘等电脑常用的外接设备也有需求同时使用。但是，智能手机和平板电脑由于自身轻薄的结构特点，通常只设有一个USB接口，在需要外接多个USB设备时，将不得不连接额外的USB集线器，这一方面显得非常麻烦，另一方面，由于USB集线器体积较大，便携性差，而且不美观。
当前，新推出的智能手机、平板电脑已经开始将最新的基于USB 3.1标准的USB TYPE-C接口作为标准配置，这种USB TYPE-C接口可以支持正反向均能插接，在使用上具有很大的便利性。在USB TYPE-C接口中一共设有四根信号线：TX1+、TX2-、RX1+、RX1-，然而，由于受限于外接设备发展的局限性，智能手机和平板电脑目前都还不能很好地实现USB3.0、USB3.1标准的功能，从而使得USB TYPE-C接口得不到充分的利用。
发明内容
本发明要解决的技术问题在于，提供一种智能移动终端USB TYPE-C接口系统，能使智能移动终端上的一个USB TYPE-C接口可以外接多个符合USB 2.0标准的USB设备。
为解决上述技术问题，本发明提供如下技术方案：一种智能移动终端USB TYPE-C接口系统，包括：
USB控制器，设置于智能移动终端内；
第一USB TYPE-C接口，设置于智能移动终端内并自智能移动终端的壳体露出，其包含有两组对称排布的管脚组，每一管脚组中均设有四个传输信号的管脚TX+、TX-、RX+、RX-以及用于兼容USB 2.0接口的管脚D+和D-，所述管脚D+和管脚D-为一组，管脚TX+和管脚TX-为一组，管脚RX+和管脚RX-为一组，从而构成三组信号管脚组；
USB Hub芯片，设置于智能移动终端内部，其连接于USB控制器和第一USB TYPE-C接口之间，其具有一个上行端口及两个或三个下行端口，所述上行端口连接USB控制器，每一个下行端口均对应连接一组信号管脚组；以及
转接连接线，其设置于智能移动终端的外部，转接连接线的一端为用于与第一USB TYPE-C接口对应插接的第二USB TYPE-C接口，而另一端则分成数量与USB Hub的下行端口数量相同的USB 2.0接口，且各USB 2.0接口内的管脚与各下行端口所连接的第一USB TYPE-C接口的各管脚分别一一对应并通过连接连接线内部的分线连接至第二USB TYPE-C接口的各对应管脚上。
进一步地，所述USB Hub芯片具有3个下行端口，对应地所述转接连接线的另一端设有3个USB 2.0接口。
进一步地，所述USB控制器设置于智能移动终端的系统级芯片内。
进一步地，所述智能移动终端为智能手机或平板电脑。
采用上述技术方案后，本发明至少具有如下有益效果：本发明充分、合理地利用了智能移动终端的系统级芯片(SoC)内置的USB 3.1标准的USB控制器，并增设一个符合USB 2.0标准的USB HUB芯片，同时复用智能移动终端上的第一USB TYPE-C接口中的传输信号的管脚TX+、TX-、RX+、RX-作为USB 2.0接口的管脚D+和管脚D-，从而可以将1个第一USB TYPE-C接口拓展成最多3个USB 2.0接口。再配合特制的转接连接线，可 同时插接最多3个USB设备，例如键盘，鼠标和U盘。一方面提供了更好的用户体验；另一方面，也还避免了用户想同时使用多个USB2.0标准的USB设备时需要额外连接携带不方便的USB集线器的麻烦。
