请参见图1-3，本实用新型提供了一种功率分配单元，用于充电桩，功率分配单元包括：壳体1、辅助电源2、电表3、PDU模组和铜排4，壳体1具有收容腔10，PDU模组固定连接于收容腔10内，壳体1开设有连通收容腔10的第一开口、第二开口和第三开口，辅助电源2可拆卸装配于收容腔10且正对于第一开口，电表3固定连接于收容腔10内且正对于第二开口，铜排4部分位于收容腔10内且部分突出于第三开口。
本实用新型的功率分配单元包括具有收容腔10的壳体1，以及装配于收容腔10内的辅助电源2、电表3、PDU模组和铜排4，其中，辅助电源2位于第一开口处，因此可以从第一开口中将辅助电源2拆卸下来，以对辅助电源2进行维修；电表3位于第二开口处，因此可以从第二开口处对电表3进行读数；而铜排4突出于第三开口，既可以作为PDU模组的输入接口，也可以作为充电桩内部配电的输出接口。本实用新型将原本分散安装于充电桩桩体的电气件整合到收容腔10内，把充电桩系统复杂的功能集成为模块，实现功能模块化。一方面，可以简化充电桩机柜内部布局，使得充电桩机柜内部空间得以释放，可以用于扩展其它功能。另一方面，充电桩机柜外壳不再需要大量压铆来安装部件，使得充电桩机柜外观质量得到提升。本实用新型的功率分配单元与充电桩系统解耦，从而可以单独生产备货，单独测试，单独包装运输到现场安装，改善充电桩生产交付周期。
进一步地，功率分配单元还包括部分位于收容腔10内且部分位于第一开口外的第一装配板5，第一装配板5位于第一开口外的部分与壳体1可拆卸连接，辅助电源2固定连接于第一装配板5上。
具体的，在本实施例中，壳体1主要为长方体架构，即壳体1具有六个侧面，其中第一开口开设于壳体1的第一侧面。辅助电源2可以通过螺钉连接或卡扣连接等方式固定连接于第一装配板5上。而第一装配板5有部分位于第一开口外，且第一装配板5中位于第一开口外的部分与壳体1可拆卸连接，比如可以是螺钉连接、卡扣连接等。因此，在对辅助电源2进行拆卸时，可以将第一装配板5中位于第一开口外的部分与壳体1进行拆卸，再通过第一开口将第一装配板5从收容腔10拉取出，此时固定连接于第一装配板5上的辅助电源2也将从第一开口被拉取，从而可以方便对辅助电源2进行维修测试。在进行拆卸时，只需要将第一装配板5中位于第一开口外的部分与壳体1进行拆卸分离即可。本实用新型具有简易的安装方式，方便现场的维护检修。

在本实施例中，功率分配单元还包括监控模块6，与相关技术相比，本实用新型的功率分配单元还设置有监控功能，且监控模块6与充电桩系统解耦，因此可以单独生产、单独测试，有利于全球范围内不同客户的定制需求。监控模块6用于连接铜排4、以及PDU模组的控制器、接触器等，也可以与上位机通讯，实现组网。另外，监控模块6与收容腔10可拆卸连接，因此，当需要对监控模块6进行测试时，可以通过第四开口，将监控模块6从壳体1上拆卸下来。本实用新型具有简易的安装方式，方便现场的维护检修。
进一步地，功率分配单元还包括部分位于收容腔10内且部分位于第四开口外的第二装配板7，第二装配板7与壳体1可拆卸连接，监控模块6固定连接于第二装配板7。
具体的，在本实施例中，第四开口开设于壳体1的第二侧面，第一侧面和第二侧面垂直设置，且第二侧面位于第一侧面的顶部，第四开口主要开设于第二侧面中靠近第一侧面的一边，即在收容腔10靠近第一侧面和第二侧面的区域，同时收容有辅助电源2和监控模块6，因此，壳体1在该区域处，还形成有突出于长方体表面的凸起区域，使得壳体1的一侧面形成为L型，从而可以更好地装配辅助电源2和监控模块6，且具有一定的美观性。监控模块6可以通过螺钉连接或卡扣连接等方式固定连接于第二装配板7上。而第二装配板7有部分位于第四开口外，且第二装配板7中位于第四开口外的部分与壳体1可拆卸连接，比如可以是螺钉连接、卡扣连接等。因此，在对监控模块6进行拆卸时，可以将第二装配板7中位于第四开口外的部分与壳体1进行拆卸，再通过第四开口将第二装配板7从收容腔10拉取出，此时固定连接于第二装配板7上的辅助电源2也将从第四开口被拉取，从而可以方便对辅助电源2进行维修测试。在进行拆卸时，只需要将第二装配板7中位于第四开口外的部分与壳体1进行拆卸分离即可，本实用新型具有简易的安装方式，方便现场的维护检修。
进一步地，第二装配板7包括第二主体部71和第二连接部72，第二主体部71与第二连接部72垂直设置，第二主体部71位于收容腔10内，监控模块6固定连接于第二主体部71上；第二连接部72设置于第四开口外且与壳体1可拆卸连接。
具体的，在本实施例中，第二装配板7为L型，其中一边为第二主体部71，另外一边为第二连接部72。第四开口为矩形状，第四开口的左边与第二侧面的左边具有第三间隔、第四开口的右边与第二侧面的右边具有第四间隔，本实施例中设置有两个第二装配板7，其中一个第二装配板7的第二主体部71固定连接于监控模块6的左边且位于收容腔10内，另一个第二装配板7的第二主体部71固定连接于监控模块6的右边且位于收容腔10内。当第二主体部71位于收容腔10内时，与第一主体部51垂直设置的第一连接部52即可位于第三间隔和第四间隔处，第三和第四间隔为第二侧面的一部分，两个第二连接部72分别与第三、第四间隔可拆卸连接，比如可以是螺钉连接、卡扣连接等。在对监控模块6进行拆卸时，可以先将两个第二连接部72分别与第三、第四间隔进行螺钉拆卸或卡扣拆卸等，再拉动第二连接部72，与第二连接部72垂直设置的第一主体部51即可通过第四开口从收容腔10被拉取出，此时固定连接于第二主体部71上的监控模块6也将从第四开口被拉取，从而可以方便对监控模块6进行维修。在进行拆卸时，只需要将第二连接部72与壳体1进行拆卸分离即可，因此，还具有操作方便优点，降低了维修难度。
进一步地，壳体1开设有若干散热孔；PDU模组集成有散热控制单元，散热控制单元可根据收容腔10内的热量变化进行强制散热控制。具体的，功率分配单元与充电桩桩体装配连接，功率分配单元位于充电桩的风道内。传统功率分配单元都不自带散热模块，尤其是充电桩行业大功率快充需求后，短时温升很大，而本实施例的散热控制单元可检测收容腔10内的温度值，同时将检测到的温度值与预设阈值进行对比，当检测到的温度值大于预设阈值时，散热控制单元将控制PDU模组等进行散热，将热量通过散热量带出收容腔10外，进而带出桩体外，因此本实用新型可以提高产品的可靠性和安全性。
进一步地，功率分配单元还包括风机8，壳体1开设有第五开口，功率分配单元可拆卸装配于收容腔10内且正对于第五开口。具体的，第五开口开设于壳体1的第三侧面，且第三侧面与第一侧面相对设置，通过风机8可以加速PDU模组的散热，将热量带出收容腔10外，进而将热量带出充电桩外。另外，风机8为可选配置，当需求大功率配置时，可以配轴流风扇加强PDU的散热能力。
进一步地，功率分配单元还包括第三装配板9，第三装配板9盖合第三开口，第三装配板9开设有通孔，铜排4可通过通孔突出于收容腔10外。具体的，在本实施例中，在壳体1的第四侧面和第五侧面均开设有第三开口，其中第四侧面和第五侧面分别在第一侧面的左右两侧，且功率分配单元包括两个第三装配板9和多个铜排4，各个第三装配板9上还开设有多个通孔，铜排4与通孔一一对应。两个第三装配板9的通孔可以相同也可以不同。铜排4既是PDU模组的输入接口，也是充电桩内部配电的输出接口，可以根据功率需求、充电枪头、调配等进行灵活配置，比如铜排4可根据需求配双枪或单枪。本实用新型可通过更换铜排4实现功率分配单元的规则组合变化，因此，具有适应面广、可拓展性强的优点。
进一步地，壳体1安装有滑块，充电桩桩体安装有导轨，滑块与导轨滑动连接。具体的，在壳体1第六侧面上安装有滑块，其中第六侧面与第二侧面相对设置，通过滑块与导轨的滑动连接，可以方便功率分配单元与充电桩桩体的装配。当功率分配单元滑动到充电桩桩体的特定位置时，铜排4伸出收容腔10部分将与桩体的铜排4对应配合。应当理解的是，第一、第二、第三、第四和第五侧面的位置关系是可以根据功率分配单元的布局以及充电桩桩体的布局而改变，即第一、第二、第三、第四和第五开口的设置位置本实用新型并不做具体限定，可以根据实际情况进行调整。而设置有滑块的侧面，只需要不同于设置开口的侧面即可。进一步地，第一侧面还安装有握持部11，握持部11可以是把手、凸块等等，从而可以方便用户对功率分配单元进行握持。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其它实施例的相关描述。
以上为对本实用新型所提供的技术方案的描述，对于本领域的技术人员，依据本实用新型实施例的思想，在具体实施方式及应用范围上均会有改变之处，综上，本说明书内容不应理解为对本实用新型的限制。
