 具体实施方式
需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图1-图5描述根据本公开实施例的电池箱体100。
参照图1和图3，根据本公开第一方面的电池箱体100，电池箱体100具有间隔布置的电池仓101和电器仓102，也就是说，电池箱体100形成有两个仓，分别为电池仓101和电器仓102，电池仓101与电器仓102分隔开布置，换言之，电池仓101与电器仓102相互隔离。电池仓101用于容纳电池模块300，电器仓102用于布置电器元件200。
本公开的电池箱体100，通过设置间隔的电池仓101和电器仓102，可以将电池模块300和电器元件200隔开，相比现有技术中电池模块300和电器元件200未隔开的方案，本实施例的电池箱体100在电池模块300发生热失控时，可以保证电器元件200的正常运行，防止控制系统失效，从而能够保证动力装置1000的运行安全，同时，电器仓102可以将电器元件200集成在电器仓102内，方便对电器元件200的检修，还可以将电池模块300中的能量集成到电器仓102内，统一输出。
根据本公开的实施例的电池箱体100，通过设置间隔的电池仓101和电器仓102，可以将电池模块300和电器元件200隔开，保证动力装置1000的运行安全，同时，方便对电器元件200的检修，还可以统一输出电池模块300中的能量。
根据本公开的一些实施例，参照图1，电器仓102布置在电池箱体100在第一方向（如图1所示的前后方向）上的一端（如图1所示的电池箱体100的前端），第一方向为电池箱体100的长度方向或宽度方向，也就是说，第一方向可以是电池箱体100的长度方向，第一方向也可以是电池箱体100的宽度方向。由此，可以将电池仓101和电器仓102隔开，使电池仓101和电器仓102互不影响，同时，电器仓102在电池箱体100的一端，可以方便电器元件200的安装。
根据本公开的一些实施例，参照图1和图3，电池箱体100可以包括：框架10。框架10包括第一梁11、第二梁、第三梁12和电器梁13，第一梁11、第二梁、第三梁12和电器梁13首尾顺次相连为矩形环状并在内侧限定出顶部和底部均敞开的电池仓101，电器梁13的内部形成有电器仓102。
通过设置框架10，可以形成电池仓101和电器仓102，同时，可以保证电池箱体100的强度，提高电池箱体100的使用寿命；通过设置电器梁13，可以方便电器仓102的形成，同时，可以保证电器仓102的强度，提高电器仓102的使用寿命，此外还可以通过电器梁13将电池仓101和电器仓102隔开，减少零部件的使用，从而能够对电池箱体100的减重降本，再有，此种结构形式简单，不占用电池箱体100的多余空间，能够提高电池箱体100内部的空间利用率。
进一步地，在电池箱体100左右方向的中部位置还设有平行于第一梁11和第三梁12的第四梁14，第四梁14的两端分别与电器梁13和第三梁12相连，这样第四梁14与第一梁11、第二梁、第三梁12和电器梁13构成日字形的框架10，从而能够进一步加强电池箱体100的结构，防止电池箱体100被破坏，同时，第四梁14将电池仓101分隔成两个仓，这样可以方便电池模块300的安装。优选的，第一梁11、第二梁、第三梁12、第四梁14和电器梁13之间采用焊接连接，这样可以保证电池箱体100的强度。
再有，电器梁13从电池箱体100长度方向（例如图1中所示的左右方向）上的一端延伸至另一端，电器仓102从电器梁13的长度方向上的一端延伸到另一端。此时，电器仓102的长度与电池仓101的长度大体相等，电器仓102的长度大体等于电池箱体100的长度。由此，不仅可以增大电器仓102的长度，增大电器仓102的容积，还可以方便电池模块300集成的端头伸入到电器仓102内部，同时，无需考虑电池模块300输出端头位置与电器梁13在前后方向是否对应的问题，方便电池模块300的集成端头可以在任意位置进入电器仓102内。
例如，如图1所示，电器仓102形成于电器梁13内部，电器仓102在电器梁13的内部且沿左右方向延伸，第一梁11、第二梁、第三梁12和电器梁13形成电池仓101，电池仓101布置在电器仓102的后端，电池箱体100的顶部敞开，电池模块300可以从上至下进入电池箱体100，方便电池模块300的安装。
根据本公开的一些实施例，参照图1和图2，电器梁13可以包括梁主体131和盖板132，梁主体131限定出背离电池仓101的一侧敞开的电器仓102，盖板132封盖在电器仓102的敞开侧。通过设置梁主体131，可以方便电器仓102的形成，还可以方便电器元件200的安装；通过设置盖板132，可以封盖电器仓102的开口处，从而对电器仓102进行有效保护。另外，在对电器元件200检修时，拆卸盖板132就可以观察电器元件200的状态，方便检修操作。
例如，如图1所示，梁主体131为前侧敞开的矩形体，电器元件200可以从前向后安装在电器仓102内部，盖板132呈板型，盖板132将梁主体131的敞开侧封盖。优选的，盖板132和梁主体131采用焊接连接，这样可以保证盖板132和梁主体131的连接强度，同时，将盖板132和梁主体131的焊点打磨后就能够将盖板132拆卸，从而能够方便盖板132的拆卸与安装。
根据本公开的一些可选实施例，参照图1和图2，梁主体131上形成有贯通梁主体131的第一引出口和第二引出口，第一引出口与第二引出口间隔布置，第一引出口连通在电池仓101与电器仓102之间，第一引出口用于电池模块300的采集组件310伸入电器仓102，第二引出口连通在电池仓101与电器仓102之间，第二引出口用于电池模块300的汇流件320伸入电器仓102。通过设置第一引出口，可以方便采集组件310伸入到电器仓102内，保证采集组件310采集的信号传输到电器元件200内；通过设置第二引出口，方便汇流件320伸入到电器仓102内，保证汇流件320中的能量传输到电器元件200上，统一输出。
根据本公开的一些实施例，参照图1，第一引出口包括两个，两个第一引出口分别形成于梁主体131在长度方向（如图1所示的左右方向）上的两端（如图1所示的梁主体131左右两端），第二引出口形成于梁主体131在长度方向上的中部位置。由此，第一引出口和第二引出口间隔布置，使第一引出口和第二引出口互不影响，同时，可以方便采集组件310从第一引出口伸出和汇流件320从第二引出口伸出与电器元件200的连接。
进一步地，如图1所示，在电池模块300进入电池仓101之前，采集组件310向前伸出，在电池模块300进入电池仓101时，电池模块300左侧的采集组件310向右弯折且与电池模块300的左右方向平行，电池模块300右侧的采集组件310向左弯折且与电池模块300的左右方向平行，采集组件310经过第一引出口后与电器元件200连接，汇流件320设有两个向前凸出的连接部，连接部伸出第二引出口后连接在电器元件200上。
根据本公开的一些实施例，参照图1、图2和图3，电池箱体100还可以包括插接座30，插接座30固定于电器仓102内用于连接采集组件310，盖板132上形成有沿盖板132的厚度方向（如图1所示盖板132的前后方向）贯通盖板132的第一过线孔1321，第一过线孔1321用于穿设与插接座30和/或采集组件310相连的第一线束，也就是说，第一过线孔1321可以用于穿设第一线束，第一线束可以与插接座30相连，第一线束也可以与采集组件310相连。通过设置第一过线孔1321，可以将第一线束从第一过线孔1321引出，方便第一线束与控制板连接；插接座30和采集组件310插接连接，此种连接形式简单，成本低廉，便于批量化生产，同时，插接连接能够保证多种信号的同时传输，保证传输效果。
例如，如图2和图3所示，插接座30呈长条形且沿上下方向布置，在上下方向设有间隔布置的多个信号接收线，多个信号接收线插入到采集组件310内部，实现信号的传输。 
根据本公开的一些实施例，参照图1、图2和图3，电池箱体100还可以包括输出极座20，输出极座20固定于电器仓102内用于连接汇流件320，盖板132上形成有沿盖板132的厚度方向（如图1所示盖板132的前后方向）贯通盖板132的第二过线孔1322，第二过线孔1322用于穿设与汇流件320相连的接线柱40，也就是说，第二过线孔1322用于穿设接线柱40，接线柱40与汇流件320相连。通过设置第二过线孔1322，可以将接线柱40从第二过线孔1322引出，方便接线柱40与电机连接。另外，设置第一过线孔1321和第二过线孔1322可以将第一线束与接线柱40隔开，防止第一线束和接线柱40接触发生危险。再有，汇流件320和输出极座20固定连接可以保证能量传输效果，还可以防止汇流件320传输的能量对采集组件310的信号造成影响，从而能够保证电池模块300的安全。
例如，如图1所示，第一过线孔1321设在第二过线孔1322的左侧，采集组件310与插接座30插接连接后，第一线束与插接座30连接，之后第一线束从第一过线孔1321伸出。输出极座20呈中间低两边高的凹形，汇流件320的两个连接部连接到输出极座20的两边，通过螺栓将输出极座20和汇流件320紧固连接。优选的，输出极座20为塑料件，这样可以对汇流件320与周围构件进行绝缘。
根据本公开的一些实施例，参照图1和图5，盖板132上还设有入水接口1323和出水接口1324，入水接口1323和出水接口1324用于连接换热水管400，换热水管400的至少部分位于电器仓102内，也就是说，换热水管400可以部分位于电器仓102内，换热水管400也可以全部位于电器仓102内。由此，换热水管400可以吸收电器仓102内的电器元件200散发的热量，从而能够满足电器元件200对维持恒定温度的需求，保证电器元件200的正常运行。
进一步地，如图1所示，电池箱体100内设有液冷板，液冷板中设有换热通道和与换热通道连通第一接管和第二接管，换热水管400包括进水管和出水管，进水管的一端与第一接管相连且另一端连接入水接口1323，出水管的一端与第二接管相连且另一端连接出水接口1324，液体从入水接口1323流入换热水管400的进水管，再从进水管流入液冷板的第一接管内，从第一接管流入换热通道内，之后液体从第二接管流出换热通道，从第二接管流入换热水管400的出水管，从出水接口1324流出换热水管400的出水管，完成对电池模块300和电器元件200的热交换。
根据本公开的一些实施例，参照图1，盖板132为铝系冲压件。由此，在能够保证盖板132的强度的条件下，可以降低电器仓102的重量。
根据本公开的一些实施例，参照图1，梁主体131为铝镁合金压铸件。由此，可以保证梁主体131的强度，提高梁主体131的使用寿命，同时，可以防止电器仓102变形破坏，从而能够保证电器元件200在电器仓102正常运行。优选的，梁主体131采用铸铝技术压铸形成，这样可以保证梁主体131的强度。
参照图1，根据本公开第二方面的动力装置1000，包括本实施例第一方面的电池箱体100。
