图3A为本申请实施例提供的移动终端的一种详细电路图。其中,下面以所述第一接口10为USB Micro B和所述第二接口20为POGO PIN接口为例进行详细说明。和图1中相同的部分请参考图1的描述,本申请实施例只说明与图1不同的部分。如图3A所示:
所述第一接口10的VBUS_1与所述第一在位检测电路11电连接,所述第二接口20的VBUS_2与所述第二在位检测电路电连接21,所述数据检测电路12与所述第一接口10 和所述第二接口20的USB_ID电连接,所述第一在位检测电路11与所述处理器30的第一输入端3011电连接、所述第二在位检测电路21与所述处理器30的第一输入端3012电连接,所述数据检测电路12与所述处理器30的第三输入端3013电连接。
所述开关电路40包括第一开关Q1,第二开关Q2,第三开关Q3,数据通道开关S1;
所述第一开关Q1的第一端4011与所述第一接口10的电源端口VBUS_1电连接,所述第一开关Q1的第二端4012与所述电池50电连接;所述第一开关Q1的控制端4013与所述处理器30的第一输出端3021电连接;
所述第二开关Q2的第一端4021与所述第二接口20的电源端口VBUS_2电连接,所述第二开关Q2的第二端4022与所述电池50电连接;所述第二开关Q2的控制端4023与所述处理器30的第二输出端3022电连接;
所述第三开关Q3的第一端4031与所述第一接口10的电源端口VBUS_1电连接,所述第三开关Q3的第二端4032与所述第二接口20的电源端口VBUS_2电连接;所述第三开关Q3的控制端4033与所述处理器30的第三输出端3023电连接;
所述数据通道开关S1的控制端S13与所述处理器30的第四输出端3024电连接,所述数据通道开关S1包含第一端,第二端,第三端,所述数据通道开关S1的第一端(S111,S112)与所述第一接口的数据端(D+,D-)电连接,所述数据通道开关S1的第二端(S121,S122)与所述第二接口的数据端(D+,D-)电连接,所述数据通道开关S1的第三端(S141,S142)与所述处理器的数据端口(D+,D-)电连接,即S111与所述第一接口10的D+电连接,S112与所述第一接口10的D-电连接,S121与所述第二接口20的D+电连接,S122与所述第二接口20的D-电连接,S141与所述处理器30的D+电连接,S142与所述处理器30的D-电连接。
需要说明的是,所述第一在位检测电路和所述第二在位检测电路采用现有技术中检测电路和检测方法,在这里不再赘述。所述数据检测电路,用于检测所述外围设备是否与所述移动终端进行数据交互,例如:所述数据检测电路可以为USB_ID在位检测电路。如图3所示,初始时,所述数据通道开关S1默认导通第一接口10和所述处理器30(导通S1的S111端口和S141端口,S112端口和S142端口),所述第一接口10和所述第二接口20的USB_ID端口相连通,且与所述USB_ID在位检测电路电连接,无论哪个接口接入OTG设备,USB_ID端口均会被拉低触发中断,处理器通过数据端口(D+、D-)对USB设备进行识别,如果该接口无数据传输,则会切换S1开关状态(S1导通S121端口和S141端口,S122端口和S142端口),从而导通处理器和另外接口的数据通路,如果有数据传输,则S1开关状态保持不变(S1保持导通S1的S111端口和S141端口,S112端口和S142端口),即保持处理器与当前接口的数据通路,进行正常的数据传输。可以根据第一接口10和第二接口20的类型来设置S1的默认状态,从安全方面考虑,优先将Micro B接口与所述处理器默认导通,如果两个均为Micro B接口,随机选择其中一个接口即可。
如图3A所示,所述第一接口10可以为USB Micro B接口,第二接口可以为POGO PIN接口;如图3B所示,所述第一接口10和所述第二接口也可以均为USB Micro B接口;或者,如图3C所示,使用一个底座作为转接器,将如图3A中的POGO PIN接口转换成Micro B接口。移动终端也可以通过所述底座与所述POGO PIN接口连接,将所述POGO PIN接口转换成Type A接口,图中未示出。当移动终端的两个接口无法满足外围设备的接入需求时,移动终端可以配置底座等转换器,将移动终端的接口转换成需要的接口,来满足不同接口 的需要。
如图3A所示,该第一接口10和该第二接口20的5个端口分别为VBUS,D+,D-,USB_ID,地。第二接口20为POGO PIN接口,因为外围设备接入第二接口时无需使用线缆,可以直接通过POGO PIN接口接入移动终端的第二接口,如移动终端为二合一笔记本电脑中的主体部分,主体部分可以通过POGO PIN接口与键盘连接。因此为用户使用移动终端提供方便。如果移动终端还需要支持USB Micro B接口,则可使用底座将Pogo Pin接口转换成USB Micro B接口,所述底座可以对移动终端起到支撑作用。
所述外围设备包括电源适配器、OTG设备,个人电脑等。下面以同时插入移动终端的第一接口和第二接口的外围设备的几种情况来分别阐述本发明实施例中的开关电路如何工作的。

表1
Figure PCTCN2018097622-appb-000001
需要说明的是,如果在移动终端中的第一接口和第二接口同时插入两个OTG设备时,因为数据传输通路只有一个,所以同一时间只能使用一个接口进行数据传输,为了避免冲突,可以将先插入的OTG设备配置最高优先级,控制数据通道开关S1导通先插入OTG设备的接口与处理器的数据通道。也可以分时导通两个接口与处理器的数据通道,使得两个接口上的数据可以分时传输,本申请实施例不做具体限定。
如果在移动终端中的第一接口和第二接口同时插入两个电源适配器时,两个在位检测电路都会检测到外围设备在位,处理器将先插入的电源适配器配置最高优先级。当然,处理器也可以将后插入的电源适配器配置最高优先级,本申请实施例不做具体限定。
如果在移动终端中的仅有一个接口被使用,则需要控制开关电路设置另外一个接口不会有电流通过,保证移动终端的安全性。例如:在所述第一接口插入所述外围设备,所述第二接口不接入任何外围设备,则所述处理器控制第一开关闭合,第二开关和第三开关断开,使得所述第二接口的VBUS_2没有电流通过;在所述第二接口插入所述外围设备,所述第一接口不接入任何外围设备,则所述处理器控制第一开关和第三开关断开,第二开闭合,使得所述第一接口的VBUS_1没有电流通过。
以上,仅为本申请的具体实施方式,但本申请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申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以权利要求的保护范围为准。
