附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部分，本发明的示意性实施例及其说明用于解释本发明，并不构成对本发明的不当限定。在附图中：
图1是根据本发明实施例的充电装置的结构示意图；
图2是根据本发明实施例的另一充电装置的结构示意图；
图3是根据本发明实施例的又一充电装置的结构示意图；
图4是根据本发明实施例的充电方法的流程示意图。
具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在所写的说明书、权利要求书、以及附图中所特别指出的结构来实现和获得。
本发明实施例提供了一种充电装置，如图1所示，该充电装置包括：
至少两个第一接口12；
充电整流保护电路14，设置为接收至少两个第一接口12分别传输的第一电流，并将各个第一电流整流为输出电流，输出电流的值等于各个第一电流的值的总和；
第二接口16，设置为接收并输出充电整流保护电路14传输的输出电流。
通过至少两个第一接口12，通过充电整流保护电路14将从至少两个第一接口12传输的第一电流整流为输出电流，并通过第二接口16输出上述输出电流，相对于相关技术中的充电装置受到物理器件特性的限制，不仅解决了相关技术中的充电装置存在充电速度缓慢、充电效率较低的问题，进而达到了缩短电子设备电池的充电时间，提高充电效率的效果。
目前，大多电子设备的USB(Universal Serial Bus，通用串行总线)接口为标准USB接口，可以满足各种工业和民用需要。标准USB接口的输出电压是+5V，输出电 流是500mA。当输出电流超过500mA会有风险，例如，会对连接在该标准USB接口上的U盘或移动硬盘造成性能上的损伤。因此，通过增大该标准USB接口的输出电流的方法来提高充电效率会受到物理器件特性的限制。
在本发明实施例中，充电装置包括至少两个第一接口12，该至少两个第一接口12可以为标准USB接口，该至少两个第一接口12可以分别连接在任意的标准USB接口上，例如，电脑上的标准USB接口、标准USB插座等，该至少两个第一接口12接收上述任意的标准USB接口的第一电流，并分别将接收到的第一电流传输至充电整流保护电路14。
其中，如图2所示，该至少两个第一接口12可以通过导线24与充电整流保护电路14连接，并且该至少两个第一接口12可以连接在相同的具有标准USB接口的设备上，也可以连接在不同的具有标准USB接口的设备上。例如，本发明的充电装置设置有两个第一接口，分别为接口A和接口B，那么，当使用本发明的充电装置进行充电时，接口A和接口B可以插设在同一台电脑的两个标准USB接口上；也可以接口A插设在一台电脑的标准USB接口上，接口B插设在另一台电脑的标准USB接口上；还可以接口A和接口B分别插设在标准USB插座上；还可以接口A插设在一台电脑的标准USB接口上，接口B插设在标准USB插座上，此处不做限制。
充电整流保护电路14接收上述至少两个第一接口12分别传输的第一电流，并将各个第一电流整流为输出电流，输出电流的值等于各个第一电流的值的总和。也就是说，以电脑充电为例，电脑的单个标准USB接口承载的电流有限，那么，在使用本发明实施例的充电装进行充电时，充电整流保护电路14保证输出电压+5V不变，输出电流为各个电流的总和，通过大电流给电池充电，缩短了充电时间。
进而，第二接口16接收并输出充电整流保护电路14传输的输出电流，当需给电子设备进行充电时，将电子设备通过与该电子设备配套的充电线插设在该第二接口16上。
作为本发明的一个可选的实施例，如图2所示，该充电装置，还可以包括：
充电指示灯18，设置为指示连接在与充电整流保护电路14连接的第二接口16上的电子设备的充电状态。
其中，该充电整流保护电路14包括检测电路20，该检测电路20与上述充电指示灯18连接，检测电路20设置为检测从第二接口16输出的电流值，若从第二接口16输出的电流值小于预设门限，则控制上述充电指示灯18开启或关闭。
具体地，充电整流保护电路14包括检测电路20，该检测电路20可以实时检测从第二接口输出的电流值，若从第二接口16输出的电流值小于预设门限，例如，现有的电子设备在充满电后，仍会接收微弱的电流，该电流一般小于50mA，也就是说，当检测电路20检测到从第二接口输出的电流值小于50mA时，则会认为该电子设备已经充满电，此时，检测电路20会传输控制信号值充电指示灯18，以控制充电指示灯的开启或关闭，例如，充电指示灯开启表示电子设备处于正常充电状态，充电指示灯关闭表示电子设备处于过充状态，当电子设备未充满电，即从第二接口16输出的电流值大于等于50mA时，检测电路20会控制充电指示灯18处于开启状态，当电子设备充满电，即从第二接口16输出的电流值小于50mA时，检测电路20会控制充电指示灯18关闭，那么用户则知道该电子设备已经充满电了，以指示用户及时拔除以免对电子设备的电池性能造成伤害。
优选地，如图3所示，充电指示灯18包括第一指示灯182及第二指示灯184；检测电路20，设置为当从第二接口16输出的电流值大于等于预设门限，则控制第一指示灯182开启、第二指示灯184关闭，以指示连接在第二接口16上的电子设备处于正常充电状态；当从第二接口16输出的电流值小于预设门限，则控制第一指示灯182关闭、第二指示灯184开启，以指示连接在第二接口16上的电子设备处于过充状态。
具体地，本发明实施例的充电指示灯18可以包括第一指示灯182及第二指示灯184，其中，第一指示灯182可以为绿灯，第二指示灯184可以为红灯，那么，绿灯亮可以表示电子设备处于正常充电状态，红灯亮可以表示电子设备处于过充状态，与上述方案类似的，当从第二接口16输出的电流值大于等于50mA时，检测电路20会控制第一指示灯182开启、第二指示灯184关闭(即绿灯亮、红灯灭)，当从第二接口16输出的电流值小于50mA时，检测电路20会控制第一指示灯182关闭、第二指示灯184开启(即绿灯灭、红灯亮)，更加直观地提醒用户在电子设备已充满电时，及时拔除以免对电子设备的电池性能造成伤害。
需要说明的是，本发明实施例对充电指示灯的数量、颜色、尺寸及形状等并不做限制，并且，本发明的充电装置也可以包含其它具有指示电子设备充电状态的装置，例如，显示屏、语音扬声器等，也应在本发明的保护范围内。
如图2所示，充电装置，还可以包括：
壳体22，充电整流保护电路14设置于壳体11的内部，至少两个第一接口12通过导线24与充电整流保护电路14连接并裸露于壳体22的外部，壳体22设置设置为嵌入第二接口16的开口(图2中未标出)。
需要说明的是，该壳体的材料可以为绝缘材料。
另外，至少两个第一接口及第二接口均可以为通用串行总线USB接口。
本发明实施例提供的充电装置，包括至少两个第一接口(也称标准USB接口公头)、第二接口(也称标准USB接口母头)、充电整流保护电路、充电指示灯、壳体，该壳体可以为长方形结构，标准USB接口公头通过数据线(其功能相当于图2中的导线24)和壳体相连，标准USB接口母头设置于壳体后端的中空结构内(即嵌入壳体的开口内)，其中，壳体后端是指与上述标准USB接口公头一端远离的一端；充电整流保护装置(其功能相当于图2中的充电整流保护电路14)设置于壳体内部，设置为将至少两个标准USB接口公头输入的第一电流整流为输出电流，例如，若有两个标准USB接口公头，则充电整流保护装置设置为将两个USB接口公头的输入电流整形为双倍输出，并可以防止电脑突发的读写硬盘或者运行某些软件CPU或显卡全频工作时出现输出电压/电流波动，使得充电相对稳定；充电指示灯可以设置于壳体内部，可以显示电子设备的充电状态，正常充电状态显示绿灯，当充电完成电池处于过充状态时，显示红灯，提示用户充电已完成，及时拔除以免对电子设备的电池性能造成伤害。
采用本发明实施例的充电装置，连接在电脑标准USB接口和电子设备(例如手机)充电线之间，与相关技术相比，可以让至少两个第一接口同时对手机充电，达到了手机充电电流倍增效果，节省了充电时间，提高了充电效率和充电安全性。
在本实施例中提供了一种充电方法，如图4所示，该流程包括如下步骤：
S102，接收至少两路第一电流；
S104，将至少两路第一电流整流为输出电流，输出电流的值等于各个第一电流的值的总和；
S106，将输出电流传输至电子设备。
通过上述步骤，解决了现有技术中USB接口充电速度缓慢、充电效率较低的问题，进而达到了缩短电子设备电池的充电时间，尤其是缩短利用USB接口的充电时间效果。
对应于图1所示，充电装置接收至少两路第一电流，其中，充电装置包括至少两个第一接口12，该至少两个第一接口12可以为标准USB接口，可以分别连接在任意的标准USB接口上，例如，电脑上的标准USB接口、标准USB插座等，该至少两个第一接口12接收上述任意的标准USB接口的第一电流，并分别将接收到的第一电流 传输至充电整流保护电路14。充电整流保护电路14接收上述至少两个第一接口12分别传输的第一电流，并将各个第一电流整流为输出电流，输出电流的值等于各个第一电流的值的总和。也就是说，以电脑充电为例，电脑的单个标准USB接口承载的电流有限，那么，在使用本发明实施例的充电装进行充电时，充电整流保护电路14保证输出电压+5V不变，输出电流为各个电流的总和，通过大电流给电池充电，缩短了充电时间。第二接口16接收并输出充电整流保护电路14传输的输出电流，当需给电子设备进行充电时，将电子设备通过与该电子设备配套的充电线插设在该第二接口16上。
较优地，上述充电方法，还可以包括：
S2，检测输出的电流值；
S4，判断输出的电流值是否小于预设门限；
S6，在判断结果为是的情况下，控制充电指示灯开启或关闭，其中，充电指示灯设置为指示电子设备的充电状态。
具体地，充电整流保护电路14包括检测电路20，该检测电路20可以实时检测从第二接口输出的电流值，若从第二接口16输出的电流值小于预设门限，例如，现有的电子设备在充满电后，仍会接收微弱的电流，该电流一般小于50mA，也就是说，当检测电路20检测到从第二接口输出的电流值小于50mA时，则会认为该电子设备已经充满电，此时，检测电路20会传输控制信号值充电指示灯18，以控制充电指示灯的开启或关闭，例如，充电指示灯开启表示电子设备处于正常充电状态，充电指示灯关闭表示电子设备处于过充状态，当电子设备未充满电，即从第二接口16输出的电流值大于等于50mA时，检测电路20会控制充电指示灯18处于开启状态，当电子设备充满电，即从第二接口16输出的电流值小于50mA时，检测电路20会控制充电指示灯18关闭，那么用户则知道该电子设备已经充满电了，以指示用户及时拔除以免对电子设备的电池性能造成伤害。
若输出的电流值小于预设门限，则控制充电指示灯开启或关闭包括：
S8，若输出的电流值小于预设门限，则控制第一指示灯关闭、第二指示灯开启，以指示电子设备处于正常充电状态；
S10，若输出的电流值大于等于预设门限，则控制第一指示灯开启、第二指示灯关闭，以指示电子设备处于过充状态；其中，充电指示灯包括第一指示灯及第二指示灯。
优选地，如图3所示，充电指示灯18包括第一指示灯182及第二指示灯184；检测电路20，设置为当从第二接口16输出的电流值大于等于预设门限，则控制第一指示灯182开启、第二指示灯184关闭，以指示连接在第二接口16上的电子设备处于正常充电状态；当从第二接口16输出的电流值小于预设门限，则控制第一指示灯182关闭、第二指示灯184开启，以指示连接在第二接口16上的电子设备处于过充状态。
具体地，本发明实施例的充电指示灯18可以包括第一指示灯182及第二指示灯184，其中，第一指示灯182可以为绿灯，第二指示灯184可以为红灯，那么，绿灯亮可以表示电子设备处于正常充电状态，红灯亮可以表示电子设备处于过充状态，与上述方案类似的，当从第二接口16输出的电流值大于等于50mA时，检测电路20会控制第一指示灯182开启、第二指示灯184关闭(即绿灯亮、红灯灭)，当从第二接口16输出的电流值小于50mA时，检测电路20会控制第一指示灯182关闭、第二指示灯184开启(即绿灯灭、红灯亮)，更加直观地提醒用户在电子设备已充满电时，及时拔除以免对电子设备的电池性能造成伤害。
需要说明的是，本发明实施例对充电指示灯的数量、颜色、尺寸及形状等并不做限制，并且，本发明的充电装置也可以包含其它具有指示电子设备充电状态的装置，例如，显示屏、语音扬声器等，也应在本发明的保护范围内。
以本发明实施例的充电装置设置有两个第一接口，并通过电脑为手机充电为例进行说明，充电时，首先保证两个标准USB接口公头(即图3中的第一接口12)和电脑的两个标准USB接口相连接，随后标准USB接口母头(即图3中的第二接口16)插上充电线对手机等电子设备进行充电。具体的，电脑单个标准USB接口的输入功率为P1＝U1*I1，其中P1为USB接口的输入功率，U1为输入电压，I1为输入电流。对于两个标准USB接口，输入功率倍增P＝2*P1，在保持输出电压不变的情况下，充电装置的输出电流倍增，进而达到快速充电的目的。本发明通过放大充电电流的方式使充电时间急剧缩短，显示了快速充电的优越性。
