下面参考附图描述根据本公开实施例的全地形车1。
如图1-图3所示，根据本公开实施例的全地形车1包括车架10、发动机20、动力电机30、发动机散热器40、电机散热器50和水泵60。
发动机20安装于车架10，动力电机30安装于车架10，动力电机30连接有控制器组件31。例如，动力电机30通过发动机20设置在车架10上，动力电机30可以通过连接法兰固定在发动机20的一侧。即动力电机30固定于发动机20的一侧，且动力电机30与发动机20传动连接，动力电机30可以在发动机20的驱动下进行发电，同时也可以输出动力，驱动车轮。其中，动力电机30可以为纯电机，也可以为动力发电机。
发动机散热器40和电机散热器50均设置在车架10上，发动机散热器40通过发动 机冷却水管41与发动机20相连，冷却液可以在发动机散热器40和发动机20之间流动，在发动机20工作时，高温冷却液可以流动至发动机散热器40内，发动机散热器40可以有效散热，从而可以降低冷却液的温度，再使得冷却液回流到发动机20中。电机散热器50通过电机冷却水管51与动力电机30相连，冷却液可以在电机散热器50和动力电机30之间流动，在动力电机30工作时，高温冷却液可以流动至电机散热器50内，电机散热器50可以有效散热，从而可以降低冷却液的温度，再使得冷却液回流到动力电机30中，电机冷却水管51可以进一步地与控制器组件31相连，以同时对控制器组件31进行散热。需要说明的是，发动机20和动力电机30的最佳工作温度不同，因此单独设置散热器，可以保证发动机20和动力电机30能够保持在最佳运行温度。
具体地，如图1所示，发动机散热器40设置在车架10的前部，电机散热器50设置在发动机散热器40的前表面上。由于动力电机30运行温度低于发动机20的运行温度，因此将电机散热器50设置在发动机散热器40的前表面上，保证空气先对电机散热器50降温，然后再对发动机散热器40降温。例如，电机散热器50设置在发动机散热器40的前表面上半部分，这样可以将发动机散热器40和电机散热器50设置在一起，可以方便散热器在车架10上的整体布置，而且可以方便发动机散热器40和电机散热器50的散热，可以保证发动机20和动力电机30的工作温度。
水泵60设于电机冷却水管51，具体地，动力电机30连接有控制器组件31，控制器组件31与电机冷却水管51相连且位于动力电机30和电机散热器50之间，水泵60设置在控制器组件31与电机散热器50之间的电机冷却水管51上。水泵60可以提供动力，这样可以使得电机散热器50和动力电机30组成的循环回路循环顺畅。
现有技术中，基本是将水泵集成在动力电机内部，由于动力电机安装位置较低，所以水泵会与电机散热器存在较大高度差，导致水泵扬程不够的问题，进而影响冷却液循环效率，不利于响散热。本发明通过将水泵60设置在动力电机30、控制器组件31与电机散热器50之间的电机冷却水管51上，冷却液由电机散热器51到水泵60，再流入控制器组件31和动力电机30内，即水泵60设置在动力电机30的外部，可以提高水泵60的设置高度，进而提高水泵60的扬程，提高循环效率；另外，由于将水泵60设置在动力电机30的外部，还可以方便水泵60的维修。
由此，发动机散热器40可以单独为发动机20的冷却液散热，电机散热器50可以单独为动力电机30的冷却液散热，从而使得发动机20和动力电机30能够处于适宜的工作温度，这样发动机20和动力电机30工作效率高，并且互不干涉。
下面参考附图描述根据本公开实施例的水泵60。
如图2和图3所示，根据本公开实施例的水泵60包括泵壳100、叶轮200、无刷电 机300和控制总成400。
泵壳100设有进水口101和出水口102，叶轮200可旋转地设于泵壳100内，叶轮200旋转时将水从进水口101导入泵壳100并从出水口102导出泵壳100。无刷电机300设于泵壳100内，无刷电机300与叶轮200相连且驱动叶轮200旋转。控制总成400设于泵壳100内且与无刷电机300相连。
根据本公开实施例的全地形车1，水泵60采用无刷电机300，不仅整体机构尺寸变小、安装空间需求小，能够在相同体积下达到需要的性能，从而提高整车的空间利用率，而且电机30由于为无电刷结构，不会产生摩擦阻力，也不会产生热量消耗能量，从而能量损失小，能量转换效率高。此外，无刷电机300高速运转时不会产生电磁干扰，从而保证全地形车1其它电器元件的性能可靠性，且采用无刷电机300的水泵60在EMC(电磁兼容)法规测试中较易通过。
因此，根据本公开的实施例的全地形车1具有空间利用率高、能量转化效率高、性能可靠等优点。
本领域的技术人员可以理解地是，根据本公开实施例的全地形车1的水泵60不限于应用在上述设置在电机冷却水管51上的实施例，水泵60也可以应用于全地形车1的任何需要的位置。
在本公开的一些具体实施例中，如图3所示，无刷电机300包括定子310和转子320。
转子320可旋转地设于定子310内，转子320为永磁件且与叶轮200传动连接。
进一步地，控制总成400具有逆变电路，所述逆变电路将输入的直流电转换成定子310的线圈中的交流电，从而带动转子320旋转，且逆变电路隔离了线圈产生的振荡信号，防止其反馈至直流电路中。
在本公开的一些具体示例中，如图3所示，为了合理利用泵壳100内的空间，避免水泵60内各部件之间相互影响和干涉，泵壳100内限定出电气室103、定子室104和叶轮室105，控制总成400设于电气室103，定子310设于定子室104，叶轮200设于叶轮室105，进水口101和出水口102均与叶轮室105连通。
具体而言，如图3所示，泵壳100包括壳体110、端盖120、中壳体130和泵头140。
端盖120安装于壳体110，且端盖120与壳体110共同限定出电气室103。中壳体130安装于壳体110，且中壳体130与壳体110共同限定出定子室104。泵头140安装于中壳体130，且泵头140与中壳体130共同限定出叶轮室105，进水口101和出水口102形成于泵头140，转子320可旋转地安装于中壳体130和泵头140，即转子320的至少一部分位于中壳体130，至少一部分位于泵头140。
其中，端盖120和控制总成400之间设有导热垫410，导热垫410可以为硅胶垫。端盖120与壳体110之间，壳体110与中壳体130之间以及中壳体130与泵头140之间可以分别通过密封圈提高装配后的密封性。
由此，可以合理在泵壳100内限定出电气室103、定子室104和叶轮室105，且通过将泵壳100分成壳体110、端盖120、中壳体130和泵头140等部分，能够方便水泵60内部元件的拆装和维护。
在本公开的一些具体实施例中，如图3所示，转子320设于叶轮室105，且转子320与叶轮200形成一体，中壳体130被构造成分隔定子310和转子320的结构。
具体地，中壳体130设有第一支撑台150，泵头140设有第二支撑台160，转子320设有转轴330，转轴330的一端可旋转地配合于第一支撑台150，转轴330的另一端可旋转地配合于第二支撑台160，从而将转子320可旋转地安装于中壳体130和泵头140，且支撑稳定可靠。
在本公开的一些具体示例中，如图3所示，为了便于水泵60的电连接，壳体110设有插接头170，插接头170内设有与控制总成400相连的插接端子180。
根据本公开实施例的全地形车1的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“具体实施例”、“具体示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本公开的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。
尽管已经示出和描述了本公开的实施例，本领域的普通技术人员可以理解：在不脱离本公开的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本公开的范围由权利要求及其等同物限定。
