请参阅图1-图3，其中，图1为本实用新型实施例提供的接地结构的接地连接部采用接地螺纹孔的三维结构示意图；图2为本实用新型实施例提供的接地结构的接地连接部采用接地螺纹孔的正面结构示意图；图3为本实用新型实施例提供的接地结构的接地连接部采用接地螺钉柱的三维结构示意图。
本实用新型实施例提供了一种接地结构，应用于电气设备，参照图1-图3，电气设备包括具有接地需求的机箱1和至少部分设置于机箱1外侧的功能器件2，其中，机箱1内安装有电器件，这些电器件具有接地需求，功能器件2是为了使得机箱1内电器件更好的工作而配置的具有相应功能的器件，其具体可以是内部设置有磁性元器件的电感壳；还可以是辅助机箱散热的散热器；又或者是为机箱1配备的其他功能器件；另外，该接地结构具体可以包括至少一个接地连接部3，该接地连接部3设置于功能器件2处于机箱的外侧部分的壳壁上；其中，功能器件2的壳壁与机箱1导电连接。
该接地结构，在实际应用过程中，通过将接地连接部3布置在功能器件2的壳壁上，而功能器件2的壳壁又与机箱1导电连接，因此，能够满足电气设 备的机箱1接地需求，同时无需占据机箱1内部空间，也即无需考虑接地连接部3与机箱1内电气件之间的安规空间(电气间隙、爬电距离等)，更有利于机箱小型化。
需要说明的是，接地结构一般还包括接地标识4，接地标识4设置于功能器件2的外壳壁上且靠近接地连接部3布置，从而能够方便用户或操作人员执行接地操作。
另外需要说明的是，上述接地连接部3的数量可以设计为一个，也可以设计成多个，比如两个。实际应用过程中，还可以选择实际需求选择相应数量的接地连接部，在此不做具体的限定。
此外，上述接地连接部3具体可以采用接地螺纹孔，配合接地螺栓及接地线缆与大地连接；也可以采用接地螺钉柱，配合接地螺母及接地线缆与大地连接。当然可以理解的是，接地连接部3采用接地螺纹孔和接地螺钉柱的方式，仅仅是本实用新型实施例的举例而已，实际应用过程中，还可以采用本领域技术人员常用的其他接地连接部的形式，比如接地连接片或者接地线夹的方式等，实际应用过程中，可以根据实际需求选择配置，在此不做更具体的限定。

在一些具体的实施方案中，上述功能器件2具体可以为压铸件，也可以是机加工件、3D打印件或型材件等，实际应用过程中，可以根据实际需求选择对应的加工方式制作而成，在此不做更具体的限定。
需要说明的是，上述接地连接部3与功能器件2具体可以设计成一体成型结构，也可以设计成分体式固定连接结构，实际应用过程中，可以根据接地连接部3的具体结构形式，选择对应的接地连接部3在功能器件2上的成型方式，当接地连接部3采用接地螺钉柱时，可以采用分体式固定连接结构，比如，焊接的方式固定在功能器件2，当然也可以采用一体成型；当接地连接部3采用接地螺纹孔时，接地连接部3更优选设计成与功能器件2一体成型的结构，比 如可以通过机加工螺纹孔实现。
进一步的实施方案中，当接地结构同时包括接地连接部3和接地标识4时，上述接地连接部3和接地标识4这两者中的至少一者可以设计成与功能器件2为一体成型结构。也即，可以是接地连接部3和接地标识4这两者中一者可以设计成与功能器件2一体成型(比如压铸成型)，另一者可以通过外加装或后加工等方式设置在功能器件2上；也可以是接地连接部3和接地标识4这两者均以一体成型的方式设置于功能器件2上，实际应用过程中，可以根据实际需求选择布置。比如，当功能器件2为压铸件时，接地连接部3(比如，接地螺纹孔(参照图1和图2)或接地螺钉柱(参照图3))和接地标识4均可以通过模具成型，不用额外增设其他零部件的安装固定工序，有助于减少零部件数量、减少工序和工时，降低综合成本。
在一些具体的实施方案中，上述接地标识4在功能器件2的外壳壁呈现的结构形式可以为形成于外壳壁上的凸起结构或凹陷结构。通过设计成该种结构形式，使得接地标识4不容易因外界环境的长期影响而损坏，使用寿命更加长久。
需要说明的是，上述接地标识4具体可以采用钢印敲制的方式设置于外壳壁，也可以采用激光打标方式的设置于外壳壁，又或者是通过粘贴标签的方式，还可以是印字的方式设置于外壳壁。实际应用过程中，可以根据实际需求选择对应的加工布置方式，在此不做更具体的限定。
另外，本实用新型还提供了一种电气设备，包括接地结构，其中该接地结构为上述任一方案所描述的接地结构。由于上述接地结构具有前述技术效果，因此具有该接地结构的电气设备也应具有相应的技术效果，在此不再赘述。
进一步的实施方案中，上述电气设备具体可以是光伏发电用电气设备，比如，逆变器、整流器或汇流箱等，只要是具有接地需求和功能器件的电气设备均可，在此不做具体的限定。
需要说明的是，本说明书中的各个实施例均采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。
