具体实施方式
为了能够更清楚地理解本公开的上述目的、特征和优点，下面将对本公开的方案进行进一步描述。需要说明的是，在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其他不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不 是全部的实施例。
如图1至图3所示，本公开提供一种电驱动总成，包括壳体、电机控制器2、电机和升压装置。其中，壳体具有容纳腔。电机控制器2设置于容纳腔，电机控制器2内具有功率模块电路。电机设置于壳体上，且电机电性连接于功率模块电路。升压装置设置于容纳腔内，升压装置包括滤波电路和继电器4，滤波电路电性连接于电机控制器2和继电器4，继电器4电性连接于电机的电机中性点。
可以理解的是，通过将升压装置和电机控制器2均设置于壳体的容纳腔内，能够对电机控制器2和升压装置进行防护，而且将升压装置与电机、电机控制器2集成设置，结构紧凑，整个电驱动总成全部位于副车架30上，提高了车辆被追尾时的高压安全性；而且由于滤波电路和继电器4均电性连接于电机控制器2，继电器4连接于电机的电机中性点，由动力电池20引出的高压正极输入线束8可通过电机控制器2连接滤波电路，经滤波电路滤波后经继电器4与电机中性点连接，随后经电机和功率模块电路升压后可对动力电池20进行充电，因此升压装置与电机控制器2共负极，能够将动力电池20到外置的升压装置之间两根高压连接线优化为动力电池20到电驱动总成之间的一根高压线，且省去电驱动单元的负极到升压装置的高压线束，因此能够减少高压线的长度，降低成本。
除此之外，相比现有技术需要安装电驱动单元和升压装置，将升压装置集成到电驱动总成，可简化装配工序，降低工时，且由于继电器4连接于电机的电机中性点，可使得升压装置利用电机的电感，从而可省去升压装置自身的冷却设计，进一步简化装配工序，降低工时。
如图1所示，在一些实施例中，电驱动总成还包括排线6，排线6设置于容纳腔内，排线6一端连接于继电器4，另一端连接于电机控制器2，电机控制器2能够通过排线6控制继电器4的通断。如此设置，将对升压装置的低压控制线集成设置到电驱动总成内，并通过电机控制器2通过排线6控制继电器4的通断，可降低线束的长度，降低成本。
在一些实施例中，电机控制器2包括PCB板21，继电器4包括电路板，排线6连接于PCB板21和电路板之间，电机控制器2通过排线6控制继电器4的通断，进而实现升压电路的通断。
如图1和图2所示，在一些实施例中，电驱动总成还包括设置于容纳腔内的第一导电排5，所述电机控制器2具有电性连接于滤波电路的第二导电排22，第二导电排22连接于第一导电排5。
需要说明的是，第一导电排5和第二导电排22可拆卸连接，便于第一导电排5和/或第二导电排22的更换。
进一步地，壳体上设置有供动力电池20的高压正极输入线束8插入的接插件7，高压正极输入线束8能够电性连接于第一导电排5。可以理解的是，接插件7对高压正极输入线束8进行固定，使得第一导电排5和高压正极输入线束8电性连接，第一导电排5电连接于第二导电排22，进而实现了高压正极输入线束8和电机控制器2的电性连接。上述接插件7优选为PIN接插件。
通过采用接插件7、第一导电排5和第二导电排22实现高压正极输入线束8和电机控 制器2的连接，能够使得高压正极输入线束8和电机控制器2稳定连接。
如图1和图2所示，滤波电路设置于电机控制器2内，电机控制器2上设置有电性连接于滤波电路的第三导电排24，继电器4上设置有能够电性连接于第三导电排24的输入导电排41。上述滤波电路设置于电机控制器2内，如此电机控制器2和升压装置共用一套滤波电路。
需要说明的是，第三导电排24和输入导电排41可拆卸连接，便于电驱动总成的组装和拆卸，也便于第三导电排24和/或输入导电排41的更换。
如图1和图2所示，继电器4上还设置有输出导电排42，输出导电排42连接于电机中性点。在一些实施例中，电机中性点设置有中性点导电排31，上述继电器4的输出导电排42连接于中性点导电排31。
如图1和图2所示，在一些实施例中，壳体包括可拆卸连接的第一壳体11和第二壳体12，第一壳体11和第二壳体12之间形成上述容纳腔，继电器4安装于第二壳体12上。上述第一导电排5和接插件7均安装于第二壳体12上，上述电机控制器2安装于第一壳体11上。
进一步地，壳体上对应第一导电排5和第二导电排22的位置开设有安装孔121，安装孔121能够供紧固件穿过以连接第一导电排5和第二导电排22。具体地，上述第二壳体12上对应第一导电排5和第二导电排22的位置开设有安装孔121。通过设置安装孔121，能够在第一壳体11和第二壳体12连接后通过紧固件对第一导电排5和第二导电排22进行固定，保证第一导电排5和第二导电排22连接稳定。上述紧固件优选为螺钉。
在一些实施例中，壳体上还设置有能够盖设于安装孔121上的遮盖板123，遮盖板123可拆卸连接于壳体。具体地，遮盖板123可拆卸连接于第二壳体12。通过设置遮盖板123，能够在通过紧固件连接第一导电排5和第二导电排22后对安装孔121进行遮盖，避免杂物或者水汽进入到容纳腔内。
在一些实施例中，第二壳体12上对应第一导电排5与高压正极输入线束8的连接位置、第三导电排24与输入导电排41的连接位置及输出导电排42和中性点导电排31的连接位置均开设有供紧固件穿过的安装孔121。紧固件优选为螺钉，能够在第一壳体11和第二壳体12连接后对位于容纳腔内的第一导电排5与高压正极输入线束8、第三导电排24与输入导电排41及输出导电排42和中性点导电排31进行固定，保证连接稳定性。在一些实施例中，第二壳体12上对应每个上述安装孔121均设置有遮盖板123。
如图1和图2所示，电机上设置有第一UVW导电排32，电机控制器2具有第二UVW导电排23，第一UVW导电排32穿过第二壳体12并伸入容纳腔内，第一UVW导电排32连接于第二UVW导电排23。
进一步地，如图2所示，第二壳体12上设置有至少四个间隔设置的隔断边122，相邻两个隔断边122之间形成一隔断腔。上述第一UVW导电排32包括第一U排321、第一V排322和第一W排323，第一U排321、第一V排322和第一W排323分别位于不同的隔断腔。通过设置隔断边122形成隔断腔，能够对第一U排321、第一V排322和第一W排 323进行隔挡，提高安全性。
进一步地，上述中性点导电排31穿过第二壳体12并伸入容纳腔内，且中性点导电排31位于一个隔断腔内。在一些实施例中，中性点导电排31与第一U排321、第一V排322和第一W排323分别位于不同的隔断腔，此时隔断边122设置有五个。通过隔断边122将中性点导电排31和第一UVW导电排32隔开，提高安全性。
进一步地，第二UVW导电排23包括第二U排、第二V排和第二W排，第二壳体12上对应第一U排321和第二U排的连接位置、第一V排322和第二V排的连接位置及第一W排323和第二W排的连接位置均对应开设有供紧固件穿过的安装孔121。紧固件优选为螺钉，能够保证第一UVW导电排32和第二UVW导电排23的连接稳定性。第二壳体12上对应每个上述安装孔121均设置有遮盖板123。
如图3所示，电驱动总成还包括减速器。壳体还包括第三壳体13，第三壳体13可拆卸连接于第二壳体12，减速器设置于第三壳体13和第二壳体12之间，第二壳体12上开设有供减速器的输出轴穿过的穿设孔124。
进一步地，壳体还包括第四壳体14，第四壳体14可拆卸连接于第三壳体13，电机设置于第三壳体13和第四壳体14之间，电机连接于上述减速器。在一些实施例中，电机的中性点导电排31、第一UVW导电排32均穿过第三壳体13和第二壳体12，并伸入至容纳腔内。
通过将壳体设置为可拆卸连接的第一壳体11、第二壳体12、第三壳体13和第四壳体14，便于电驱动总成的组装，并且将电机和减速器与电机控制器2和升压装置相隔开，避免相互之间产生干扰。
如图3所示，电驱动总成还包括高压正极输入线束8、正极高压线束9和负极高压线束10，高压正极输入线束8一端能够连接于动力电池20，另一端能够通过电机控制器2电性连接于滤波电路，正极高压线束9和负极高压线束10均能够连接于电机控制器2的功率模块电路和动力电池20。
在一些实施例中，高压正极输入线束8可插接于接插件7，并通过第一导电排5和第二导电排22电性连接于滤波电路，正极高压线束9连接于动力电池20的正极端口和电机控制器2的功率模块电路，负极高压线束10连接于动力电池20的负极端口和电机控制器2的功率模块电路。
结合上文，可以理解的是，动力电池20引出的高压正极输入线束8通过接插件7与第一导电排5的一端连接，第一导电排5的另一端与电机控制器2的第二导电排22连接，第二导电排22连接于滤波电路，滤波电路对正极输入进行滤波，滤波后经过第三导电排24与继电器4的输入导电排41连接，继电器4通过输出导电排42与电机的中性点导电排31连接，电机的第二UVW导电排23与电机控制器2的第一UVW导电排32连接，最后经功率模块电路升压后连接到动力电池20的正负极对动力电池20进行充电。
在此过程中，电机控制器2通过排线6控制继电器4的通断，实现控制升压电路通断的目的。
需要说明的是，上述第一导电排5、第二导电排22、第三导电排24、第一UVW导电排 32、第二UVW导电排23、中性点导电排31、输入导电排41和输出导电排42均优选为铜排。
该电驱动总成将升压装置集成在三合一电驱动单元内部，升压装置与电机控制器2共负极，动力电池20到电驱动总成之间只需要一根高压正极输入线束8、一根正极高压线束9和一根负极高压线束10，升压装置的低压控制线束(即上述排线6)集成到电驱动总成内部，且取消了升压装置的冷却设计和接地设计，省去了升压装置与整车间的多个连接管线，且无需通过螺栓将升压装置固定在后地板，简化了后驱动桥总装时的装配工序。
而且相比于技术，升压装置无需与高压配电总成(ODU)模块层叠布置，从而不侵占车身Z向空间，增大后备箱体积；且取消了升压装置到动力电池20之间从副车架30顶部走线的高压线，从而解决了高压线束和线槽侵占乘员舱的Z向空间，影响乘客舒适性的问题。
基于同一个发明构思，结合上述实施例的电驱动总成的描述，本实施例提供一种车辆，该车辆具有上述实施例的电驱动总成相应的技术效果，在此不再赘述。
一种车辆，包括上述实施例的电驱动总成和动力电池20，动力电池20电性连接于电驱动总成。具体地，动力电池20上引出的高压正极输入线束8插接于接插件7，电驱动总成上引出的正极高压线束9和负极高压线束10均连接于动力电池20。当动力电池20接入充电桩后，经过电驱动总成对动力电池20进行快速充电。
如图4所示，上述车辆还包括副车架30和后保险杠40，上述电驱动总成安装于副车架30。在车辆的前进方向上，动力电池20位于电驱动总成前方，后保险杠40位于副车架30后方。其中，车辆的前进方向为图4中的ba方向。
如此，升压装置位于副车架30上，电驱动总成在副车架30和后保险杠40之间没有连接动力电池20的高压线，提高了车辆被追尾撞击时的高压安全性能。
需要说明的是，在本文中，诸如“第一”和“第二”等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
以上所述仅是本公开的具体实施方式，使本领域技术人员能够理解或实现本公开。对这些实施例的多种修改对本领域的技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本公开的精神或范围的情况下，在其它实施例中实现。因此，本公开将不会被限制于本文所述的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
