在一些具体示例中，也可以是在线路板200的连接线路上焊接连接触头(例如连接母头或者公头)，而功能机构300通过连接公头或者连接母头与连接线路上的连接触头进行插接，然后通过螺钉、螺栓或者螺杆等固定件固定在线路板200上。可以理解，在这种情况下，在线路板200上可以设有螺纹孔或者螺纹柱。
可选的，本申请实施例中，交流充电组件的工作功率可以是3kw、5kw、7kw等；当然，也可以是例如15kw、30kw等功率，本申请实施例中对此不做限定。
具体的，本申请实施例中，壳体100可以是绝缘材料制成，例如硬质塑料。当然，壳体100也可以是其他现有技术中使用的绝缘材料，本申请实施例中对此不再一一列举。
进一步的，参照图3所示，壳体100包括一侧具有开口1012的主壳体101、以及盖设于主壳体101的开口1012处的盖体102，盖体102与主壳体101围成壳体100的壳腔。
在具体生产时，将安装有功能机构300的线路板200安装在主壳体101内，具体可以通过螺钉、螺栓或者螺杆等固定件将线路板200固定在主壳体101内。然后，将盖体102盖设在主壳体101的开口1012处，从而将线路板200和设置在线路板200 上的功能机构300封装在壳体100内。这样，能够对安装腔室内的线路板200和功能机构300进行有效保护，延长交流充电组件10的使用寿命。
本申请实施例中，如图3所示，在壳体100内填充有绝缘导热材料。
其中，绝缘导热材料可以是导热胶或者导热硅胶，导热胶可以通过一体灌封的方式填充在主壳体101内，然后将盖体102盖设在主壳体101的开口处。这样，一体灌封的导热胶能够与盖体102形成良好的密封，能够进一步加强对线路板200和功能机构300的保护。
通过在壳体100内填充绝缘导热材料，这样，绝缘导热材料能够迅速将功能机构300产生的热量导走，能够提高交流充电组件10的散热效率，避免功能机构300过热的情况发生。也就是说，通过填充绝缘导热材料后，还能够进一步提高交流充电组件10的充电功率。
本申请实施例中，通过在壳体100内设置线路板200，并且功能机构300设置在线路板200上，也就是将功能机构300与线路板200集成在一起，这样，能够节省连接功能机构300的各个组成单元之间的导线所占用空间，使得交流充电组件10的整体结构紧凑，能够减小交流充电组件10的整体结构，便于布设推广。并且，因为多个功能机构300直接安装在线路板200上，也能够方便功能机构300的安装连接，提高安装效率，节省安装成本。
参照图2-图6所示，图4是本申请实施例提供的交流充电组件的主视图，图5是本申请实施例提供的交流充电组件中线路板与功能机构的装配结构示意图，图6是图4的主视图。功能机构300包括均设置于线路板200上的控制单元302、第一漏电检测单元301以及开关元件305。开关元件305连接于控制单元302和输出端202之间。
第一漏电检测单元301与控制单元302相连接且用于检测流入第一漏电检测单元301的电流值。控制单元302用于根据第一漏电检测单元301检测到的电流值控制开关元件305的通断。
其中，如图2所示，第一漏电检测单元301可以连接于输入端201和控制单元302之间，也可以是第一漏电检测单元301的单元输出端与控制单元302连接，第一漏电检测单元301的单元输入端为线路板200的输入端201。
可以理解，为新能源汽车进行充电的充电桩通常布设在停车场或者车库等位置，在较多的情况下，为露天布设，因此，对电能的使用安全性需要特别注意。本申请实施例中，通过设置第一漏电检测单元301，第一漏电检测单元301能够检测线路板200是否漏电或短路，并在检测到漏电或短路时，控制开关元件305断开，从而能够保证交流充电组件10使用的安全性。
可以理解的是，第一漏电检测单元301可以将所检测的流入第一漏电检测单元301的电流的电流值转化成漏电信号发送给控制单元302，控制单元302对漏电信号进行处理，将上述第一漏电检测单元301所检测的电流值与安全电流值上限(比如可以在30mA-100mA之间)进行比较，如果大于安全电流值上限则控制开关元件305断开。例如，在流入第一漏电检测单元301的电流的电流值小于15mA时，可以不进行动作。在流入第一漏电检测单元301的电流的电流值较大时，例如大于30mA时，控制单元302控制开关元件305断开，从而达到保护的目的。
具体的，参照图1b、图3和图5所示，本申请实施例中，第一漏电检测单元301包括：检测本体3011和开关手柄3012；检测本体3011设置在线路板200上；开关手柄3012与检测本体3011连接，并位于检测本体3011背离线路板200的一侧；开关手柄3012延伸至壳体100的外部。
这样，通过设置开关手柄3012，在交流充电组件10发生故障或者漏电的情况下，能够及时对交流充电组件10进行急停，能够对整个设备电路的通断进行控制，能够有效保护交流充电组件10和被充电的新能源汽车。避免危险情况发生。
可选的，本申请实施例中，第一漏电检测单元301可以是空气开关或者漏电保护开关。其中，开关手柄3012可以是D型手柄或者B型手柄等，本申请实施例中对开关手柄3012的具体形式不做限定。
可以理解，通过设置开关手柄3012，在充电完成后，可以通过开关手柄3012对整个交流充电组件10进行断电，这样，在交流充电组件10不使用时，也能够较好的对交流充电组件10进行保护，避免漏电的危险情况发生。
可选的，本申请实施例中，控制单元302可以是中央处理器(Central Processing Unit，CPU)、微控制单元(Microcontroller Unit，MCU)或者现场可编程门阵列(Field-Programmable Gate Array，FPGA)等。
本申请实施例中开关元件305可以是利用小电流去控制大电流运作的自动开关，例如继电器。继电器是当输入量(激励量)的变化达到规定要求时，在电气输出电路中使被控量发生预定的阶跃变化的一种电器。在电路中起着自动调节、安全保护和转换电路的作用。具体的，本申请实施例中，继电器可以是板载继电器。
板载继电器根据控制单元302的控制信号来控制连接线路与充电枪之间的通断。例如，在用户刷卡或者扫描二维码后，控制单元302输出控制信号给继电器，继电器控制连接线路与充电枪之间导通。在用户完成充电后，例如充电枪拔出时或者缴费后，控制单元302输出控制信号给继电器，继电器切换至断开状态。
第一漏电检测单元301与壳体100之间的关系不唯一，在一些实施例中，如图3所示，第一漏电检测单元301包括漏电单元壳体3015，漏电单元壳体3015与壳体100分体设计。
在另一些实施例中，如图7～图12所示，图7为本申请另一些实施例中的交流充电组件10的结构示意图，图8为图7的交流充电组件10拆去端子保护罩后的结构示意图，图9为图7的交流充电组件10另一侧的结构示意图，图10、图11为图7的交流充电组件10在不同的视角下的***图，图12为图7的交流充电组件10拆去壳体100后的结构示意图。
漏电单元壳体3015与壳体100为一体结构。
通过将漏电单元壳体3015与壳体100一体成型，这样可以减少交流充电组件10的零件数目，从而可以方便交流充电组件10的组装，提高交流充电组件10的组装效率。
继续参照图2、图3和图5所示，本申请实施例中，功能机构300还包括：电能计量单元303，电能计量单元303连接于输入端201和控制单元302之间电能计量单元303用于计量流过电能计量单元303的电量，从而在使用时方便用户获知所充电的 电量。
具体的，如图2所示，电能计量单元303连接于第一漏电检测单元301和控制单元302之间，这样第一漏电检测单元301可以对电能计量单元303起到一定的保护作用，以避免电流过大时损害电能计量单元303。
本申请实施例中电能计量单元303可以是电能计量芯片(例如，ADE7755、SA9904B、ATT7026A、CS5463、RN8290D等型号的计量芯片)。在一些具体示例中，电能计量芯片可以采用满足JJG 1148-2018电动汽车交流充电在国家计量鉴定规程要求的计量芯片。这样，使得本申请实施例提供的交流充电组件10不仅仅可以用于对新能源汽车进行充电，还可以作为普通电表使用，扩展了交流充电组件10的使用范围。
在一些实施例中，如图7～图10所示，主壳体101的开口1012处设有用于铅封的第一穿线孔1011，盖体102上设有用于铅封的第二穿线孔1021，第一穿线孔1011与第二穿线孔1021相对设置。这样，当盖体102盖在主壳体101的开口上之后，可以将连接线穿在第一穿线孔1011与第二穿线孔1021中，然后再对第一穿线孔1011与第二穿线孔1021进行铅封。在铅封之后，主壳体101和盖体102不容易被打开，从而防止用户对位于壳体100内的电能计量单元303进行篡改，以影响电能计量单元303对电能计量的准确性。
通常，在使用充电桩对新能源汽车进行充电时，可能会用到一些通讯功能。例如，通过扫描二维码消费、通过***或者通过蓝牙绑定新能源汽车等。为此，参照图2和图4所示，本申请实施例中，功能机构300还包括：通信接口304，通信接口304与控制单元302相连接，通信接口304被配置为与通信单元连接。
具体的，本申请实施例中，通信单元可以是射频识别电子标签(Radio Frequency Identification，RFID)，可以通过RFID刷卡对充电枪进行解锁等，从而对新能源汽车进行充电；当然，也可以通过RFID进行***，例如根据充电时间长度进行收费。
可以理解，上述RFID仅作为一种示例进行说明，本申请实施例中，通信单元还可以是蓝牙、无线保真(Wireless Fidelity，Wi-Fi)、***移动通信技术(the 4th generation mobile communication technology，4G)、第五代移动通信技术(5th generation mobile networks，5G)或者是刷卡器等。
通过功能通信接口304，能够有效扩展交流充电组件10的各项通信功能，方便用户使用。
在一些可能的方式中，通信接口304也可以是与功能扩展板相连接，在功能扩展板上可以同时集成上述通信单元。
进一步的，参照图1和图6所示，图6是图5的主视图。本申请实施例提供的功能机构300还包括显示器306，显示器306与控制单元302相连接，显示器306用于显示交流充电组件10的状态信息以及电能计量单元303的电能计量信息。
具体的，交流充电组件10的状态信息包括以下信息中的至少一种：充电量、当前充电状态以及故障代码。可以理解的是，状态信息还可以包括：充电时长，费用信息等等。
这样，一方面能够方便用户了解充电情况；另一方面，也能够方便调试人员对交流充电组件10进行调试和故障排查，提高了故障排查效率。
可选的，显示器306可以是触摸屏或者触控屏，在触摸屏或者触控屏上可以设置虚拟交互按键；通过虚拟交互按键可以对交流充电组件10进行调试和故障排除。在一些可能的方式中，显示器306也可以是普通的液晶显示屏，而交互按键可以是设置在显示器306的一侧的物理按键。
当然，在一些可能的方式中，控制单元302上还可以连接有多个指示灯，多个指示灯可以延伸到壳体100的外部，或者在壳体100上设置透明罩，指示灯可以延伸到透明罩内。指示灯可以是工作状态指示灯、电源状态指示灯或者故障报警指示灯中的一种或多种。
如图13～图18所示，图13为本申请另一些实施例中的交流充电组件10的结构示意图，图14为图13的交流充电组件10的另一侧的结构示意图，图15为图13中的交流充电组件10的原理框图，图16、图17为图13中的交流充电组件10在不同视角下的***图，图18为图13的交流充电组件10拆去壳体100后的结构示意图。
交流充电组件10还包括位于壳体100外的第二漏电检测单元400，第二漏电检测单元400与输入端201电连接，第二漏电检测单元400用于根据流入第二漏电检测单元400的电流的电流值控制第二漏电检测单元400的通断。
功能机构300包括均设置于线路板200上的控制单元302以及开关元件305，开关元件305连接于控制单元302和输出端202之间，控制单元302用于根据线路板200的通电参数控制开关元件305的通断。其中，上述通电参数可以是输出功率、线路板200上流过的电量等，在此不做具体限定。
在该实施例中，由于第二漏电检测单元400设置于壳体100之外，这样就可以采用现有的漏电检测器件，比如空气开关等，作为第二漏电检测单元400，那么就可以降低第二漏电检测单元400的设计成本，从而降低了交流充电组件10的设计和制作成本。
其中，如图13和图18所示，第二漏电检测单元400可以与壳体100固定连接，这样可以使壳体100与第二漏电检测单元400形成一个整体，以方便交流充电组件10的移动和安装。
如图13和图18所示，第二漏电检测单元400包括输入接线端和输出接线端，第二漏电检测单元400的输出接线端与输入端201之间通过两个连接导线510电连接。具体地，连接导线510的一端与第二漏电检测单元400的输出接线端连接，另一端伸入壳体100中与线路板200的输入端201电连接。
为了避免两个连接导线510之间发生短路，如图18所示，每个连接导线510外套设有绝缘套520，这样可以将两个连接导线510之间绝缘，以避免两个连接导线510相接触时出现短路。
在一些实施例中，如图12和图18所示，线路板200包括第一线路板203、以及位于第一线路板203沿厚度方向一侧的第二线路板204，第二线路板204与第一线路板203电连接。
开关元件305设置于第一线路板203上，且位于第一线路板203和第二线路板204之间，控制单元302、电能计量单元303、显示器306设置于第二线路板204上。
通过这样设置，开关元件305就可以充分利用第一线路板203和第二线路板204 之间的空间，从而提高了壳体100内的空间利用率，同时将开关元件305、控制单元302、电能计量单元303、显示器306分别设置在第一线路板203和第二线路板204上，这样可以使得功能机构在线路板200上的布置更加紧凑，进而有利于缩小壳体100体积，以减小该交流充电组件10的占用空间。
其中，第二线路板204可以是双层线路板，这样控制单元302、电能计量单元303、显示器306就可以分别布置于第二线路板204的两侧，比如图10和图11所示，显示器306设置于第二线路板204的一侧，控制单元302、电能计量单元303设置于第二线路板204的另一侧，从而可以优化控制单元302、电能计量单元303、显示器306在第二线路板204上的布置，以进一步提高壳体100内的空间利用率。
如图12和图18所示，第一线路板203和第二线路板204之间可以设置支撑柱205，这样可以使得第一线路板203和第二线路板204之间形成放置开关元件305的空间。
如图12和图18所示，第一线路板203和第二线路板204之间可以通过排针206电连接，由于排针206属于刚性体不易产生晃动，这样可以保证第一线路板203和第二线路板204之间电连接的可靠性。
参照图1a和图2所示，图1a是本申请实施例提供的交流充电设备的结构示意图。该交流充电设备，包括本申请第一个方面任一可选实施方式提供的交流充电组件10和充电枪。在充电枪与新能源汽车的充电接口对接后，能够对新能源汽车进行充电。
在一些实施例中，如图1a和图2所示，交流充电设备还包括导轨20，壳体100上开设有滑槽104，滑槽104与导轨20滑动配合。其中，滑槽104可以设置在盖体102上。
在具体实施时，导轨20可以是随停车场、地下车库或者是立体车库等的建立一起布设在停车场内。在布设交流充电组件10时，通过滑槽与导轨20滑动配合，这样，不但能够方便交流充电组件10的安装和布设，提高安装布设效率，而且交流充电组件10也可以沿着导轨20移动，这样，可以和旁边的车位共享一个交流充电组件10，能够节省成本。
并且，在交流充电组件10发生故障时，能够方便的将交流充电组件10从导轨20上拆卸下来，直接更换，而故障的交流充电组件10可以返回厂家进行检修或者故障排查。这样，能够提高交流充电组件10故障时的更换效率，不会影响用户的使用，能够提高用户体验。
可选的，本申请实施例中，导轨20可以是宽度为30mm-40mm的卡轨，在一些具体示例中，导轨20可以是宽度为35mm的标准卡轨。这里需要说明的是，本申请涉及的数值和数值范围为近似值，受制造工艺的影响，可能会存在一定范围的误差，这部分误差本领域技术人员可以认为忽略不计。
以上所述，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所述权利要求的保护范围为准。
