具体实施方式
下面结合附图和实施例对本公开进行说明。
实施例一
图1A为本实施例提供的一种电源适配设备的结构示意图，本实施例可适用于多种接口的电源适配器以及导线，与TYPE-C接口的电子设备电连接以完成充电。如图1A所示，电源适配设备10包括：电源输入接口11、通讯协议芯片12、电压转换芯片13与电源输出接口14。
所述通讯协议芯片12的第一检测端与所述电源输入接口11连接，所述通讯协议芯片12的第二检测端与所述电源输出接口14连接，所述通讯协议芯片12的控制端与所述电压转换芯片13连接。
所述电压转换芯片13的输入端与所述电源输入接口11连接，所述电压转换芯片13的输出端与所述电源输出接口14连接。
电源适配设备10是一个连接于直流适配器与电子设备之间的设备，使得与电子设备不匹配的直流适配器能够顺利完成充电。其中，直流适配器是小型便携式电子设备及电子电器的供电电源变换设备，将电源提供的交流换转为电子设备能适用的直流，如手机等移动设备的充电头，或者笔记本电脑中的配适器等。一般来说，用户购买电子设备均配有直流适配器，但是，每类电子产品的适配器经常不一样，导致用户出行或者长期旅游时，需要携带的直流适配器较多，比较繁琐。
直流适配器不能与所有电子设备相匹配有两点制约因素：第一，直流适配器的接口与电子设备的接口型号不统一，不能正常物理连接；第二，每类电子设备的供电参数不一样，即使直流适配器的接口与电子设备的接口能够物理连接，也无法正常充电，有可能充电时间较长，甚至有可能由于供电电流过大造成损坏电源或者烧损电线的严重后果。例如，若平板电脑的供电参数为5V，3A， 就不能使用手机3V，2.5A的直流适配器进行充电。
电源输入接口11为与直流适配器电连接的接口，用于接收直流适配器传输的输入电压。电源输入接口11与直流适配器物理连接的方式有两种情况：当直流适配器中的适配头(充电头)与适配线(导线)为一体时，可以将电源输入接口11与适配线物理连接，即电源输出接口14直接与电子设备物理连接；当直流适配器中的适配头与适配线为分离体时，可以将电源输入接口11与适配头物理连接或者将电源输入接口11与适配线物理连接。另外，电源输入接口11的接口类型可以是USB A接口或者USB B接口。
在本实施例中，通讯协议芯片12为根据双方完成通信或服务所遵循的规则和约定，对电路中输入电压转换为目标电压的行为发出控制信号的芯片。例如，含有USB PD协议的通讯协议芯片，即基于TYPE-C端口后提出的功率传输概念，可以实现与电子设备的双向通讯的功能。而且，通讯协议芯片12可以将多档关于“供电电压与供电电流”的键值存储于一预设关系表中。
电压转换芯片13将输入的电压转换成目标电压。在本实施例中，目标电压一般为电子设备请求的电压，通过将输入的电压转换为目标电压，使得电压转换芯片13输出的电压能够与电子设备匹配，以完成对电子设备的充电。电源输出接口14为与电子设备电连接的接口，用于向电子设备输出目标电压。同样的，电源输出接口14与电子设备物理连接的方式有两种情况：当直流适配器中的适配头(充电头)与适配线(导线)为一体时，可以直接将电源输出接口14与电子设备物理连接；当直流适配器中的适配头与适配线为分离体时，可以将电源输出接口14与适配线物理连接或者将电源输出接口14与电子设备物理连接。
如图1A所示，在电源适配设备10中，通讯协议芯片12的第一检测端与电源输入接口11连接，通讯协议芯片12的第二检测端与电源输出接口14连接， 通讯协议芯片12的控制端与电压转换芯片13连接；电压转换芯片13的输入端与电源输入接口11连接，电压转换芯片13的输出端与电源输出接口14连接。
示例性的，本实施例提供的电源适配设备还包括直流适配器，直流适配器的输入端与外部电源连接，所述直流适配器的输出端与所述电源输入接口连接。
如图1B所示，其中，直流适配器20输入端与外部电源21连接，直流适配器20的输出端直接与电源适配设备10的电源输入接口11连接以实现对电子设备的供电。
示例性的，所述电源输入接口11和所述电源输出接口14中的至少一个为下述任意一种类型的接口：公头或母座。
由于电源适配设备10为直流适配器与电子设备之间的一个连接设备，因此电源适配设备10中的电源输入接口11与电源输出接口14的接口类型与电源适配器的物理连接位置有关。当电源适配设备10与直流适配器中适配头物理连接时，电源输入接口11可以设置为公头，电源输出接口14可以设置为母座；当电源适配设备10与直流适配器中适配线物理连接时，电源输入接口11可以设置为母座，电源输出接口14可以设置为公头。
示例性的，所述电源输出接口14为USB TYPE-C接口。
由于未来电子设备接口的发展趋势是统一采用TYPE-C接口，但是在未转型成功的一段时间内，传统直流适配器并未完全退出市场，造成了直流适配器20混乱使用的现象，因此，可选地，电源输出接口14设置为USB TYPE-C公头接口。电源适配设备10设置为与直流适配器20中适配线物理连接，即与电子设备直接连接的方式，以使电源适配设备10的TYPE-C公头接口能够与电子设备的TYPE-C母座接口相对应。
示例性的，图1C为电源适配设备10的一种实物示意图，15为常用USB A 型电源输入接口，16为PD通讯协议芯片，17为电压转换芯片以及18为TYPE-C电源输出接口。
示例性的，图1D为当电源适配设备10与直流适配器20物理连接时的实物示意图，151为任意非TYPE-C型母座的电源输入接口，201为直流适配器20的适配头，202为直流适配器20的适配线。其中，直流适配器20为一体式结构，即适配头201与适配线202不能分开，且适配线201的接口为非TYPE-C型的任意公头接口。当适配线201接通电源时，电源适配设备10的电源输入接口151接收直流适配器20传输的电压，并传输至电压转换芯片17，电压转换芯片17根据通讯协议芯片16的要求对接收的电源电压转换成电子设备的最佳适用电压，通过电源输出接口18传输至电子设备。采用图1D中的电源适配设备10，可以使得任意非TYPE-C型公头接口的直流适配器20成功对TYPE-C型母座接口的电子设备进行充电。
示例性的，图1E为电源适配设备10与直流适配器物理连接的又一种实物示意图，152为USB A型公头电源输入接口，181为USB A型母座电源输出接口，203为含有USB A型母座接口的适配头，204为含有USB A型公头接口的适配线。其中，直流适配器为分离式结构，即适配头203与适配线204可以分开。采用图1E中的电源适配设备10，在适配头203与适配线204之间放置电源适配器10，可以使得直流适配器能够为更多同类接口、不同供电参数的电子设备进行充电。
上述电源适配设备的电源输入接口与电源输出接口的类型不仅仅包含本实施例中所提及的接口，其他类型的接口同样适用。
本实施例提供了一种电源适配设备，基于电源输入接口、通讯协议芯片、电压转换芯片与电源输出接口，实现了电源适配器为多种与该电源适配器不匹 配的电子设备供电的可能性，解决了相关技术中直流适配器(直流电源适配器)不适用TYPE-C型USB接口的电子设备而导致资源浪费的问题，便于用户出行携带同一直流适配器即可完成多种电子设备的充电任务，提高了直流适配器的利用率。
实施例二
图2为本实施例提供的一种电源适配设备的控制方法流程图，本实施例可适用于对电源适配设备的控制的情况，该方法可以由本实施例提供的电源适配设备的控制装置来执行，该装置可采用软件和/或硬件的方式实现，该装置可集成在提供电源适配设备的控制功能的设备中。如图2所示，本实施例提供的电源适配设备的控制方法可以包括以下步骤。
在步骤210中，通讯协议芯片通过第一检测端获取输入电压值。
可选地，电源适配设备包括电源输入接口、通讯协议芯片、电压转换芯片与电源输出接口。通讯协议芯片包括第一检测端、第二检测端和控制端，其中，第一检测端与电源适配设备中的电源输入接口电连接，第二检测端与电源输出接口电连接，控制端与电压转换芯片连接。
通讯协议芯片通过第一检测端在电源输入接口获取输入电压值，该电压值由与电源适配设备电连接的直流适配器所提供。由于直流适配器有将外部电源的交流电转换为直流电的功能，因此，通讯协议芯片在第一检测端获取的输入电压为直流电压值。
在步骤220中，所述通讯协议芯片通过第二检测端获取目标电压值。
可选地，通讯协议芯片的第二检测端与电源适配设备中的电源输出接口电连接。其中，电源输出接口与电子设备电连接。由于通讯协议芯片具有与电子设备双方通信的功能，因此当电子设备通过电源适配设备以及外部电源相连时， 电子设备可以将自身的最佳供电参数(目标电压值和/或目标电流值)提供给通讯协议芯片，以完成供电的需求。
在步骤230中，所述通讯协议芯片根据所述目标电压值和所述输入电压值确定电压调节信息。
可选地，又由于每台电子设备的目标电压值不一样，直流适配器的供电电压不能确定是否与相连接的电子设备相匹配，因此，通讯协议芯片根据电子设备请求的目标电压值与通过电源输入接口获取的输入电压值来获取电压调节信息。当电子设备请求的目标电压值等于电源输入接口获取的输入电压值时，通讯协议芯片最终确定的电压调节信息是不对输入电压值做处理；当电子设备请求的目标电压值不等于电源输入接口获取的输入电压值时，通讯协议芯片确定能够使输入电压转换为电子设备请求的目标电压的电压调节信息。其中，电压调节信息是电压转换芯片能够识别的信号，是为了电压转换芯片调节电路而设定的参数。
例如，假设通讯协议芯片的第一检测端通过电源输入接口获取的输入电压值为7V，第二检测端通过电源输出接口获取的目标电压值为5V，由于电子设备请求的目标电压值不等于电源输入接口的输入电压值，因此，通讯协议芯确定如何将7V电压值转换为5V电压值的电压调节信息，并将该电压调节信息发送至电压转换芯片，作为电压转换芯片转换电压的控制信号。
在步骤240中，电压转换芯片根据所述电压调节信息进行电压转换，以使电源输出接口的电压值与所述目标电压值一致。
电压转换芯片在接收到通讯协议芯片发送的电压调节信息后，根据电压调节信息将电源输入接口的输入电压值转换为电子设备请求的目标电压值，使得电源适配设备中电源输出接口的电压值与电子设备所请求的目标电压值一致。 电压转换芯片将转换后的目标电压传输至电源适配设备中的电源输出接口，并由电源输出接口提供给电子设备。
例如，电压转换芯接收到上述将7V电压值转换为5V电压值的电压调节信息后，将电源输入接口的输入电压值7V转换为电子设备请求的目标电压值5V。
示例性的，所述电压转换芯片根据所述电压调节信息进行电压转换，包括：所述电压转换芯片调整所述电压转换芯片的内部电路的电阻值；或者，通过预设通讯协议对所述电压转换芯片的内部电路进行调整。
可选地，电压转换芯片可以调整内部电路的电阻值大小，以使电源输入接口的输入电压值转换为电子设备请求的目标电压值。电压转换芯片也可以通过预设通讯协议对电压转换芯片的内部电路进行调整。其中，预设通讯协议为提前设定好的，用于调整电压转换芯片的内部电路的一个协议，通过该通讯协议来获取电子设备的目标电压，例如，集成电路总线(Inter-Integrated Circuit，IIC)通讯协议。
本实施例提供的电源适配设备的控制方法中，通讯协议芯片根据检测的目标电压值和输入电压值确定电压调节信息，电压转换芯片根据电压调节信息进行电压转换，以使电源输出接口的电压值与目标电压值匹配，实现了电源适配器为多种与该电源适配器不匹配的电子设备供电的可能性，使得直流适配器的利用率达到最大化。
实施例三
图3为本实施例提供的一种电源适配设备的控制的流程示意图，本实施例在上述实施例的基础上，所述通讯协议芯片通过第二检测端获取目标电压值，包括：所述通讯协议芯片在第二检测端上，通过PD协议获取目标设备请求的目标电压值。
如图3所示，本实施例的方法可以包括以下步骤。
在步骤310中，通讯协议芯片通过第一检测端获取输入电压值。
在步骤320中，所述通讯协议芯片在第二检测端上，通过PD协议获取目标设备请求的目标电压值。
其中，目标设备是与电源适配设备电连接的电子设备。PD协议是TYPE-C端口后提出的功率传输概念，可以实现与电子设备的双向通讯的功能。通讯协议芯片的第二检测端与电源输出接口相连接，又由于电源输出接口与目标设备相连接，因此，当通讯协议芯片的第二检测端与电源输出接口相连接时，可以获取到目标设备请求的目标电压值。
示例性的，在通过PD协议获取目标设备请求的目标电压值之后，还包括：获取所述目标设备请求的目标电流值；根据预设关系表获取所述目标电压值对应的第一电流值；如果所述目标电流值大于所述第一电流值，则将所述第一电流值作为所述目标设备请求的电流值。
其中，目标电流值为目标设备的额定电流值，预设关系表为存储于PD协议芯片源功能包Source capability package中的参考值。一般来说，PD协议芯片中的预设关系表可以包含7档电压值与电流值的键值对，且每一档的电压值与电流值一一对应。预设关系表包含的7档电压值与电流值已经足够满足目前多种小型移动电子设备的需求，也就是说，目标设备所请求的目标电压值，PD协议芯片均可以控制电压转换芯片使得在第一检测端获取的输入电压值转换为目标设备所需求的目标电压值。但是，目标电流值则不像目标电压值经过转换就可以容易解决的。
因为直流适配器与电压转换芯片本身均具有额定电流，当过流值大于额定电流值时，会烧损设备，所以目标设备所请求的目标电流值需要小于直流适配 器与电压转换芯片本身的额定电流值。
可选地，通讯PD协议芯片在获取目标设备请求的目标电压值与目标电流值后，匹配预设关系表中与请求目标电压值相同的电压一档，并获取该档位相对应的第一电流值。将目标电流值与第一电流值进行比较，当目标电流值大于第一电流值时，将第一电流值作为目标设备请求的电流，并传送至目标设备(即更新目标设备请求的目标电流值)。
在步骤330中，所述通讯协议芯片根据所述目标电压值和所述输入电压值确定电压调节信息。
在步骤340中，电压转换芯片根据所述电压调节信息进行电压转换，以使电源输出接口的电压值与所述目标电压值匹配。
本实施例提供的方法适用的情况为目标设备请求的目标电流值小于直流适配器的额定电流，但是大于PD协议芯片中与目标电压值相对应的第一电流值。
本实施例通过PD协议芯片获取目标设备请求的目标电压值与目标电流值，通过将PD协议芯片存储的与目标电压值相对应的第一电流值与目标电流值进行对比，得到目标设备的最终电压值与电流值，供给目标设备充电的同时，避免因电流过大而造成的烧损设备。
实施例四
图4为本实施例提供的一种电源适配设备的控制方法的流程示意图，本实施例在上述实施例的基础上，还包括：所述通讯协议芯片通过所述第二检测端检测目标设备的连接状态；当通过所述第二检测端检测到存在目标设备连接时，监测所述电源输出接口的实时输出电压值；若所述实时输出电压值的压降与所述目标输出电压值的比值超过预设比值阈值，则获取当前输出电流值并关闭电源线；存储所述当前输出电流值与所述实时输出电压值的键值对；并将所述键 值对发送至所述目标设备并启动所述电源线。
如图4所示，本实施例的方法可以包括以下步骤。
在步骤410中，通讯协议芯片通过第一检测端获取输入电压值。
在步骤420中，所述通讯协议芯片在第二检测端上，通过PD协议获取目标设备请求的目标电压值。
在步骤430中、所述通讯协议芯片根据所述目标电压值和所述输入电压值确定电压调节信息。
在步骤440中，电压转换芯片根据所述电压调节信息进行电压转换，以使电源输出接口的电压值与所述目标电压值匹配。
在步骤450中，所述通讯协议芯片通过所述第二检测端检测目标设备的连接状态。
可选地，通讯协议芯片的第二检测端与电源输出接口连接，因此可以检测目标设备的连接状态。当电源适配设备与直流适配器连接，且接通外部电源，未连接目标设备时，通讯协议芯片的第二检测端检测的电压为一个恒定值，电压值不发生变化。当连接目标设备时，监测到的电压值会发生变化。
在步骤460中，当通过所述第二检测端检测到存在目标设备连接时，监测所述电源输出接口的实时输出电压值。
通讯协议芯片的第二检测端持续监测电源输出接口，当获取的电压值发生变化时，可以确认第二检测端检测到存在目标设备连接，并获取电源输出接口的实时输出电压值。
或者，通讯协议芯片的第二检测端持续监测电源输出接口的实时输出电压值，而不判断是否存在目标设备。
在步骤470中，若所述实时输出电压值的压降与所述目标输出电压值的比 值超过预设比值阈值，则获取当前输出电流值并关闭电源线。
其中，预设比值阈值为根据经验而设定的一个动态值，一般设定为20％，即若实时输出电压值的压降与目标输出电压值的比值超过20％，则获取当前输出电流值并关闭电源线。
可选地，通讯协议芯片获取目标设备请求的目标电压值，与预设关系表中存储的电压相匹配，控制电压转换芯片对输入电压值进行调整，以供输出目标设备所请求的目标电压值。电压转换芯片将转换成功的目标电压值输出给电源输出接口，作为该目标设备的目标输出电压值。但是，由于目标设备请求的电流值超过直流适配器的额定电流，因此，通讯协议芯片的第二检测端获取的实时输出电压值会持续降低。当实时输出电压的压降与目标输出电压超过预设比值阈值时，为防止烧损直流适配器，此时关闭电源线(VBUS)以保护电路，并获取当前输出电流值。
在步骤480中，存储所述当前输出电流值于所述预设关系表中，与所述目标输出电压值形成新的键值对。
可选地，随着实时输出电压值的降低，当前输出电流值增加。在实际操作中，将实时输出电压值的压降与目标输出电压值的比值超过20％时的当前输出电流值作为直流适配器所能承受的最大电流值。因此，将当前输出电流值存储在预设关系表中，与该电压档位所匹配，与目标输出电压(目标电压)形成新的键值对。
由于PD通讯协议芯片中的预设关系表中的存储有7个档位的电压值与电流值的键值对，因此，将当前输出电流值存储于预设关系表中的过程，等同于更新原有预设关系表中与相应电压档位所对应的原有电流值。
在步骤490中，并将所述键值对发送至所述目标设备并启动所述电源线。
可选地，通讯协议芯片将更新后的键值对发送给目标设备，使得目标设备将更新后的键值对作为新的供电参数进行请求。另外，启动电源线，用以供电。
本实施例提供的方法适用的情况为目标设备请求的目标电流值小于PD协议芯片中与目标电压值相对应的第一电流值，但是大于直流适配器的额定电流。
可选地，当目标设备请求的目标电流值同时大于PD协议芯片中与目标电压值相对应的第一电流值，且大于直流适配器的额定电流时，应该获取出较小的电流值，分情况进行处理。
本实施例提供的电源适配设备的控制方法中，当通讯协议芯片的第二检测端监测的实时输出电压值的压降与目标输出电压值的比值超过预设比值阈值时，获取当前输出电流值作为新的预设关系表中与目标电压相对应的电流值，作为目标设备请求的新的供电参数，使得传统电源适配器能够适用多种基于USB PD通信协议的TYPE-C型USB接口的电子设备，提高电源适配器的利用率。
