下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的充电器、数据线以及充电设备进行详细地说明。
请同时参阅图1、图2和图3，其中，图1是本申请实施例提供的充电设备的电路图；图2是本申请实施例提供的充电器的电路图；图3是本申请实施例提供的数据线的电路图。
其中，本申请实施例提供的充电器1与本申请实施例提供的数据线2相互匹配，且共同构成本申请实施例提供的充电设备。
具体的，如图1所示，充电器1与数据线2之间通过Type-A接口连接，具体的：所述第一通信引脚与所述第三通信引脚连接，所述第二通信引脚与所述第四通信引脚连接。
在具体实施中，上述第一通信引脚和第三通信引脚可以是第一信号走线 上的引脚，且第二通信引脚和第四通信引脚可以是第二信号走线上的引脚。例如：在上述第一通信引脚和第三通信引脚是如图1中所示D+引脚，且上述第二通信引脚和第四通信引脚是如图1中所示D-引脚，此时，上述第一信号走线也可以称之为D+走线，上述第二信号走线也可以称之为D-走线。在D+走线和D-走线连通的情况下，充电设备可以对待充电设备进行非PD充电，该非PD充电也可以称之为：D+/D-充电，具体的是经D+引脚和D-引脚与待充电设备进行充电通信，该非PD充电处理单元13支持经D+引脚和D-引脚传输的通信信号的通信协议。
当然，上述第一通信引脚也可以是D-引脚，且第二通信引脚也可以是D+引脚，或者上述第一通信引脚和第二通信引脚还可以是其他信号传输引脚，例如：第三代通用串口总线(USB3.0)中的RX引脚和TX引脚等，在此不作具体限定。
为便于说明，如图1至图4所示实施例中，以第一通信引脚是D+引脚，且第二通信引脚是D-引脚为例进行举例说明。
在该充电设备连接电源时，充电器1与数据线2之间进行相互匹配。并且，在充电器1与数据线2匹配成时，充电器1内的D+引脚与PD充电处理单元12连接，数据线2内的D+引脚与CC引脚连接，从而可以复用Type-A接口中的D+引脚传输CC信号，从而支持PD充电功能。
具体的，在充电器1与数据线2匹配成功时，D+引脚与PD充电处理单元12连通，D-引脚与数据线匹配单元14连通，D+引脚和D-引脚均与非PD充电处理单元13断开，第二Type-A接口21中的D+引脚与CC1引脚连通，第二Type-A接口21中的D-引脚与充电器匹配单元24连通，且第二Type-A接口21和Type-C接口22中的D+引脚以及D-引脚均分别断开。
在应用中，数据线2内具有磁性元件211，充电器1可以通过数据线匹配单元14检测该磁性元件211的感应信号强度，在该感应信号强度大于或者等于预设强度时，触发数据线2与充电器1之间的匹配过程，该匹配过程中，数据线匹配单元14与充电器匹配单元24经D-引脚连通，且在确定数据线2与充电器1匹配成功时，充电器1内的D+引脚与PD充电处理单元12连接，且数据线2内的D+引脚与CC1引脚连接。
需要说明的是，在充电器1与数据线2匹配的过程中，可以将第四通信引脚与充电器匹配单元24连接，且D-引脚与数据线匹配单元14连接，以使充电器匹配单元24与数据线匹配单元14连通，从而基于D-引脚上传输的匹配信号进行相互匹配。
在具体实施中，上述基于D-引脚上传输的匹配信号进行相互匹配可以是：数据线匹配单元14经D-引脚向充电器匹配单元24发送匹配信息，该匹配信息可以是数据线匹配单元14中预先存储的字符串等。充电器匹配单元24在接收到该匹配信息时，若确定该匹配信息与充电器匹配单元24内预先存储的字符串匹配，则可以确定数据线与充电器匹配成功，并向数据线匹配单元14反馈匹配信息，以告知数据线匹配单元14数据线与充电器匹配成功。
当然，在具体实施中，还可以由充电器匹配单元24先向数据线匹配单元14发送匹配信号，并由数据线匹配单元14确定数据线与充电器是否匹配成功，其过程与上述由数据线匹配单元14先向充电器匹配单元24发送匹配信号的匹配过程相似，在此不再赘述。
需要说明的是，在具体实施中，数据线2内可以不设置磁性元件211，并在检测到数据线通过充电器连接时触发上述数据线与充电器的匹配过程，在此不作具体限定。
另外，在数据线匹配单元14检测到的感应信号强度小于所述预设强度时，可以不进行上述数据线2与充电器1之间的匹配过程，例如：充电器1在与不包括磁性元件211的数据线连接时，第一切换单元15将D-引脚与所述数据线匹配单元14断开，且还可以将D-引脚和D-引脚均与非PD充电处理单元13连接，且第二切换单元25可以将第二Type-A接口21中的D-引脚与充电器匹配单元24断开，并将第二Type-A接口21和Type-C接口22中的D-引脚以及D+引脚对应连通，以便于经D-引脚和D+引脚传输非PD充电信号。
本申请实施例提供的充电设备与第一待充电设备连接时，将D+引脚与CC1引脚连通，从而复用D+走线与第一待充电设备进行PD充电。
在一种实施方式中，上述第一待充电设备可以是支持PD充电的待充电设备；相应的，非第一待充电设备可以是不支持PD充电的待充电设备。
另外，若本申请实施例提供的充电设备与不支持PD充电的待充电设备 连接时，充电器1内的通信引脚还可以与非PD充电处理单元13连接，且数据线2内的通信引脚与对应的通信引脚连通，从而通过通信引脚与待充电设备传输非PD充电信号，以对待充电设备进行非PD充电。
在另一种实施方式中，非PD充电处理单元13和本申请实施例提供的充电设备标配的待充电设备内可以配置有预设通信协议和通用通信协议，该预设通信协议和通用通信协议的通信信号能够经通信引脚(D+引脚和D-引脚)传输。
此时，上述第一待充电设备可以是支持PD充电且为非本申请实施例提供的充电设备标配的待充电设备，即该第一待充电设备中未配置所述预设通信协议。
具体的，在本申请实施例提供的充电设备与非第一待充电设备连接时，D+引脚和D-引脚均与非PD充电处理单元13连通，且第二Type-A接口21和Type-C接口22中的D+引脚和D-引脚一一对应连通。
上述非第一待充电设备可以包括与本申请实施例提供的充电设备标配的待充电设备，以及非标配且不支持PD充电的待充电设备。
具体的，在本申请实施例提供的充电设备与标配的待充电设备连接时，D+引脚和D-引脚均与非PD充电处理单元13连通，且第二Type-A接口21和Type-C接口22中的D+引脚和D-引脚一一对应连通。
这样，可以经通信引脚传输预设通信协议的充电信号，以对标配的待充电设备进行标配充电。
另外，在本申请实施例提供的充电设备与非标配且不支持PD充电的待充电设备连接时，D+引脚和D-引脚均与非PD充电处理单元13连通，且第二Type-A接口21和Type-C接口22中的D+引脚和D-引脚一一对应连通。
这样，可以经D+引脚和D-引脚传输通用通信协议的充电信号，以对非标配的待充电设备进行常规的充电，该常规的充电与现有技术中通过D+/D-引脚进行充电协商的充电方式相同，在此不再赘述。
当然，本申请实施例提供的充电器1还可以与不匹配的数据线连接，以对待充电设备进行非PD充电，且本申请实施例提供的数据线2还可以与不匹配的充电器连接，以通过通信引脚传输非PD充电，从而对待充电设备进 行非PD充电。
请参阅图1和图2，充电器1，包括：第一Type-A接口11、PD充电处理单元12、非PD充电处理单元13、数据线匹配单元14以及第一切换单元15。
具体的，第一Type-A接口11包括D+引脚和D-引脚，第一切换单元15与D+引脚、D-引脚、数据线匹配单元14、PD充电处理单元12以及非PD充电处理单元13连接。
在充电器1与数据线2连接时，若数据线2为第一数据线，第一切换单元15将D+引脚与PD充电处理单元12连通，将D-引脚与数据线匹配单元14连通，且将D+引脚和D-引脚均与非PD充电处理单元13断开；
在充电器1与数据线2连接时，若数据线2为第二数据线，第一切换单元15将D+引脚和D-引脚均与非PD充电处理单元13连通，且将D+引脚和D-引脚均与PD充电处理单元12以及数据线匹配单元14断开。
其中，数据线匹配单元14基于获取到的磁性元件211的感应信号强度大于或者等于预设强度，且确定数据线2与充电器1匹配时，数据线2为第一数据线；数据线匹配单元14基于获取到的所述感应信号强度小于预设强度，且确定数据线2与充电器1不匹配时，数据线2为第二数据线，所述第一数据线包括磁性元件211。
在具体实施中，上述数据线匹配单元14可以包括任意能够检测磁性元件211的电磁感应信号的强度的装置，例如：如图4中所示霍尔检测单元141。
另外，上述第一数据线为如图1或图4中所示数据线2，该第一数据线与本申请实施例提供的充电器1相互匹配。
在实际应用中，与本申请实施例提供的充电器1匹配的数据线2内设置有磁性元件211，该磁性元件211具体可以是磁铁，或者电磁体等，该磁性元件211具体可以设置于数据线2的用于与充电器1连接的第二Type-A接口21内。具体的，充电器1的第一Type-A接口11可以是Type-A母座，数据线2的第二Type-A接口21可以是Type-A公座。
这样，在数据线2的Type-A公座插入充电器1的Type-A母座时，磁性元件211可以伸入充电器1的壳体内，从而使得数据线匹配单元14检测到的 感应信号强度大于或者等于预设强度，其中，上述预设强度可以根据磁性元件211磁性强度、Type-A接口的结构以及数据线匹配单元14等进行预先设置，以使第一Type-A接口11与第二Type-A接口21连接时，数据线匹配单元14检测到的感应信号强度大于或者等于该预设强度，且在第一Type-A接口11与第二Type-A接口21未连接时，数据线匹配单元14检测到的感应信号强度小于该预设强度即可。
另外，本申请实施例提供的充电器1支持PD充电和非PD充电。
其中，PD充电具体可以是：经CC引脚与待充电设备进行PD充电。
而且，非PD充电具体可以是：经D+引脚和D-引脚与待充电设备进行充电协。
另外，上述第一切换单元15可以是开关组，该开关组可以将PD充电处理单元12和非PD充电处理单元13中的一个与D+引脚连通，且该开关组还可以将非PD充电处理单元13和数据线匹配单元14中的一个与D-引脚连通。

其中，数据线匹配单元14基于获取到的所述感应信号强度和经D-引脚传输的匹配信号，确定所述数据线与所述充电器是否匹配。
在具体实施中，如图1所示，第一切换单元15的第一端与D+引脚连接， 第一切换单元15的第二端与D-引脚连接，第一切换单元15的第三端与PD充电处理单元12连接，第一切换单元15的第四端与非PD充电处理单元13连接，第一切换单元15的第五端与数据线匹配单元14连接。
这样，在数据线匹配单元14检测到的感应信号强度大于或者等于预设强度，且数据线匹配单元14经D-引脚获取到匹配信号时，第一切换单元15连通其第一端和第三端，且连通其第二端和第五端；在数据线匹配单元14检测到的感应信号强度小于预设强度，或者，数据线匹配单元14经D-引脚未获取到匹配信号时，第一切换单元15连通其第一端和第四端，且连通其第二端和第四端。
本实施方式中，在数据线匹配单元14检测到的感应信号强度大于或者等于预设强度时，触发数据线匹配单元14基于D-引脚上传输的匹配信号确定数据线2是否为与充电器1匹配的数据线。避免充电设备外的磁性元件对数据线匹配单元14检测到的感应信号强度产生干扰时，使数据线匹配单元14误判断数据线2为与充电器1的匹配结果，能够提升充电器1与数据线2之间的匹配过程的可靠性。

其中，在充电器1与数据线2连接时，若霍尔检测电路141检测到的所述感应信号强度大于或者等于所述预设强度，则第一控制器142控制所述第二开关K2将D-引脚与数据线匹配单元14连通，且D-引脚与非PD充电处理单元13断开，第一控制器142经D-引脚向所述数据线发送第一匹配信号，在第一控制器142经D-引脚接收到第二匹配信号时，确定数据线2为所述第一数据线，所述第二匹配信号为所述第一数据线对所述第一匹配信号的响应信号。
在具体实施中，上述第一匹配信号和第二匹配信号可以是相同或者相对应的匹配信号，具体的：可以是具有相同规律的编码信息，或者相同的字符串等，且上述第一控制器142内预先存储有第一匹配信号和所述第二匹配信号，或者预先存储有第一匹配信号和第二匹配信号之间的对应关系。
本实施方式中，霍尔检测电路141检测的感应信号强度为磁性元件的磁场强度，以在该磁场强度大于或者等于所述预设强度时，触发第二开关K2将D-引脚与数据线匹配单元14连通，以及触发第一控制器142基于D-引脚传输的匹配信号与数据线2进行匹配，通过电磁感应检测和匹配信号进行双重匹配，提升了匹配过程的可靠性。
请参阅图1和图3，数据线2包括：第二Type-A接口21、Type-C接口22以及连接于第二Type-A接口21与Type-C接口22之间的线缆23，数据线2上设置有充电器匹配单元24和第二切换单元25；

在数据线2分别与充电器1和待充电设备连接时，若充电器1为第二充电器，第二切换单元25将第二Type-A接口21和Type-C接口22中的D+引脚以及D-引脚一一对应连接，将第二Type-A接口21中的D+引脚与CC1引脚断开，且将第二Type-A接口21中的D-引脚与充电器匹配单元24断开；
其中，充电器匹配单元24基于经第二Type-A接口21中的D-引脚传输的匹配信号确定充电器1与数据线2匹配时，充电器1为第一充电器；充电器匹配单元24基于经第二Type-A接口21中的D-传输的匹配信号确定充电器1与数据线2不匹配时，充电器1为第二充电器。
在具体实施中，上述第一充电器为如图1或图4中所示充电器1，该第一充电器与本申请实施例提供的数据线2相互匹配。
本申请实施例提供的数据线2与本申请实施例提供的充电器1相互匹配，且数据线2执行的与充电器匹配的过程与本申请实施例提供的充电器1执行的与数据线匹配的过程相对应，在此不再赘述。
另外，在数据线2与匹配的充电器1匹配成功之前可以将第二Type-A接口21中的第四通信引脚与充电器匹配单元24连通，以经D-引脚与充电器1内的数据线匹配单元14传输匹配信号，从而执行匹配过程。
另外，在数据线2与匹配的充电器1匹配成功时，将第二Type-A接口 21中的D+引脚与CC1引脚连通，可以将充电器内的PD充电处理单元12与CC1引脚连通，从而使PD充电处理单元12经CC1引脚与待充电设备进行PD充电。
本申请实施例提供的数据线2具有与本申请实施例提供的充电器1和充电设备相同的有益效果，为避免重复，在此不再赘述。
另外，在具体实施中，在第二Type-A接口21与第一Type-A接口11连接时，磁性元件211可以位于第二Type-A接口21的朝向充电器1中心的一侧。
本实施方式，可以在第二Type-A接口21与第一Type-A接口11连接时，使磁性元件211更加深入的进入充电器1的壳体内，使充电器1壳体内的磁场强度更强，从而提升霍尔检测电路141检测到的磁场强度，从而提升霍尔检测电阻141的精确度。
进一步的，若磁性元件211位于第二Type-A接口21的第一侧边，则第二Type-A接口21中的引脚(包括：通信引脚、VBUS引脚以及GND引脚等)可以位于第二Type-A接口21的第二侧边，且第一侧边和第二侧边可以是第二Type-A接口21的相对两侧边。

其中，在数据线2与所述第一充电器连接时，第二切换单元25将CC2引脚与第一电阻Rp断开；在数据线2与所述第二充电器连接时，第二切换单元25将CC2引脚通过第一电阻Rp与线缆中的VBUS走线连接。
在具体实施中，在数据线2与其连接的充电器1匹配成功时，所述充电器1为上述第一充电器，且控制第二切换单元25将CC2引脚与第一电阻Rp断开，此时CC2可以处于高阻状态(也可以称之为断开状态)，且CC1引脚与第三通信引脚(D+引脚)连接。
另外，当数据线2与常规的充电器连接时，该充电器具有常规的Type-A 接口，且该常规的Type-A接口与现有技术中的Type-A接口的结构相同，其不能够将D+引脚与PD充电处理单元12连接，且不能够向充电器匹配单元24发送匹配信号。
这样，在本申请实施例提供的数据线2与该常规的充电器连接时，数据线2内的D+走线和D-走线连通，而CC1引脚处于高阻状态(也可以称之为断开状态)，且将Type-C接口22中的CC2引脚上拉至VBUS引脚，以允许充电设备对待充电设备充电。
此时，本申请实施例提供的数据线2的作用与现有技术中的常规Type-A to Type-C数据线相同，且充电器仅能够经D+引脚和D-引脚与待充电设备协商充电参数，即仅能够对待充电设备进行非PD充电。

本实施方式中，将第二切换单元25设置为第三开关SW1、第四开关SW3和第五开关SW2，以简化第二切换单元25的结构和控制逻辑。
作为一种可选的实施方式，充电器匹配单元24包括第二控制器，所述第二控制器与第三开关SW1的控制端、第四开关SW3的控制端和第五开关SW2的控制端分别连接，且第二控制器与第四开关SW3的第三端连接；
其中，在数据线2与充电器1连接时，第二控制器用于经第二Type-A接口21中的D-引脚获取到第一匹配信号时，确定充电器2为第一充电器，且第二控制器还用于响应于所述第一匹配信号经第二Type-A接口21中的D-引脚向所述第一充电器发送第二匹配信号。
在具体实施中，上述第二控制器可以是微控制单元(Microcontroller Unit，MCU)等，在此不作具体的限定。
本实施方式中，第二控制器中预先存储有所述第一匹配信号和所述第二匹配信号，或者预先存储有所述第一匹配信号与所述第二匹配信号之间的对应关系，从而可以在接收到第一匹配信号时，判断数据线2与匹配的第一充电器连接，并经第二Type-A接口21中的D-引脚向所述第一充电器发送对应的第二匹配信号，可以简化充电器匹配单元24的结构和进行充电器匹配的控 制逻辑。
需要说明的是，本申请实施例提供的数据线2可以与常规的充电器(即与本申请实施例提供的数据线2非标配的充电器)连接，以对待充电设备进行非PD充电，如图5所示，数据线2与常规的充电器连接时的具体工作流程如下：
步骤501、判断非标配的充电器是否接入电源。
在本步骤的判断结果为“是”的情况下，执行步骤502，否则可以等待非标配的充电器接入电源时再执行后续步骤。
步骤502、判断充电器是否插入标配的数据线。
其中，上述标配的数据线即本申请实施例提供的数据线2。
在本步骤的判断结果为“是”的情况下，执行步骤503，在本步骤的判断结果为“否”的情况下，执行步骤504。另外，在充电器未插入数据线的情况下，可以等待充电器插入数据线时再执行后续步骤。
步骤503、充电器匹配单元经D-引脚向充电器发送匹配信号。
需要说明的是，标配的数据线在未连接电源的初始状态下，SW2闭合，SW3连通D-引脚和充电器匹配单元，以使充电器匹配单元能够在连通电源时经D-引脚向充电器发送匹配信号。
步骤505、数据线与充电器匹配失败，SW2闭合，SW1连通D+走线，SW3连通D-走线。
本步骤中，由于充电器为非标配的，从而不会响应数据线经D-引脚发送的匹配信号而经D-引脚向数据线反馈对应的匹配信号，从而使得数据线与充电器匹配失败。
另外，在本步骤之后，数据线与充电器能够对待充电设备进行非PD充电。
步骤504、数据线与充电器对待充电设备进行非PD充电。
本申请实施例提供的数据线2在与常规的充电器连接时，能够通过上述工作流程连通D+走线和D-走线，从而实现经D+走线和D-走线与待充电设备进行非PD充电通信。
需要说明的是，本申请实施例提供的充电器1也可以与常规的数据线连 接，以对待充电设备进行非PD充电，如图6所示，充电器1与常规的数据线或者标配的数据线2连接时的具体工作流程如下：
步骤601、判断标配的充电器是否接入电源。
其中，上述标配的充电器即本申请实施例提供的充电器1。
在本步骤的判断结果为“是”的情况下，执行步骤602，否则可以等待非标配的充电器接入电源时再执行后续步骤。
步骤602、判断充电器是否插入标配的数据线。
其中，上述标配的数据线即本申请实施例提供的数据线2。
在本步骤的判断结果为“是”的情况下，执行步骤603，在本步骤的判断结果为“否”的情况下，执行步骤604。另外，在充电器未插入数据线的情况下，可以等待充电器插入数据线时再执行后续步骤。
步骤603、充电器匹配单元经D-引脚向充电器发送匹配信号。
需要说明的是，标配的数据线在未连接电源的初始状态下，SW2闭合，SW3连通D-引脚和充电器匹配单元，以使充电器匹配单元能够在连通电源时经D-引脚向充电器发送匹配信号。
步骤605、数据线匹配单元经D-引脚向数据线反馈匹配信号，且K2连通D-引脚与PD充电处理单元，K1断开。
需要说明的是，标配的充电器在未连接电源的初始状态下，K1断开，且K2连通D-引脚和数据线匹配单元，以使数据线匹配单元能够在连通电源时经D-引脚接收数据线发送的匹配信号，并向数据线反馈对应的匹配信号，并在通信成功后，将K2连通D-引脚与PD充电处理单元，并保持K1断开。
步骤606、标配的数据线的SW2闭合，SW1连通D+走线，SW3导通D-走线。
