节能减排是汽车产业可持续发展的关键。在这种情况下，电动车辆由于其节能环保的优势成为汽车产业可持续发展的重要组成部分。而对于电动车辆而言，电池技术又是关乎其发展的一项重要因素。
在电池技术的发展中，除了提高电池的性能外，安全问题也是一个不可忽视的问题。如果电池的安全问题不能保证，那该电池就无法使用。因此，如何增强电池的安全性，是电池技术中一个亟待解决的技术问题。
发明内容
本申请实施例提供了一种电池和用电设备，能够提高电池的强度和安全性。
第一方面，提供了一种电池，所述电池包括：第一箱体部，所述第一箱体部为具有开口的中空结构，所述第一箱体部包括与所述开口相邻的 第一侧壁；多个电池单体，容纳于所述中空结构，所述电池单体的第一壁上设置有电极端子，所述第一壁为所述电池单体的朝向所述第一侧壁的壁；多个汇流部件，用于电连接所述多个电池单体的电极端子；第一加强板，设置于所述多个电池单体中相邻的第一电池单体和第二电池单体之间，所述第一加强板与所述第一电池单体的第二壁附接，所述第二壁与所述第一电池单体的第一壁相交；加强块，所述加强块具有相对设置第一端面和第二端面，所述第一端面抵接于所述第一加强板，所述第二端面抵接于所述第一侧壁，以使所述第一侧壁与所述汇流部件之间具有间隙。
因此，本申请实施例的电池，在受到挤压或者碰撞时，第一侧壁受到的力会直接作用于与第一侧壁抵接的加强块，并通过该加强块将该作用力进一步传输至第一加强板，一方面不会使该第一侧壁受到的力直接作用于电池单体的第一壁，也就不会影响该第一壁上设置的电极端子以及汇流部件，避免电池单体发生热失控，提高了电池的安全性；另一方面也提高了电池的箱体的强度，使得该电池的箱体不易损坏，进一步提高电池的安全。
在一些实施例中，所述第一电池单体和所述第二电池单体沿第一方向排列，所述第一加强板垂直于所述第一方向，所述第一方向平行于所述第一侧壁且平行于所述第一箱体部的底壁。
这样，在第一电池单体和第二电池单体之间夹持第一加强板并安装于第一箱体部内的情况下，便于通过第一箱体部的开口安装加强块。
在一些实施例中，所述第一电池单体的电极端子和所述第二电池单体的电极端子之间不通过汇流部件连接，使得这两个电池单体之间具有足够的空间设置加强块，并且该加强块的第一端面可以与第一加强板抵接，第二端面与第一侧壁抵接。
在一些实施例中，所述第一端面以及所述第一加强板的与所述第一 端面抵接的表面相互平行且均相对于所述第一电池单体的第一壁倾斜，所述第一端面的靠近所述开口的一边远离所述第一侧壁，且所述第一端面的远离所述开口的一边靠近所述第一侧壁。
在安装时，可以通过倾斜的第一端面，将加强块自第一箱体部的开口处插进第一加强块与第一侧壁之间，进而实现加强块与第一侧壁之间紧密附接以及加强块与第一加强板之间的紧密附接。
在一些实施例中，所述加强块包括第一部分，所述第一部分包括所述第一端面，所述第一部分设置于所述第一电池单体和所述第二电池单体之间，以使得该第一部分可以夹持在第一电池单体和第二电池单体之间，则加强块在第一方向上相对固定，也就避免加强块在第一方向上的偏移。
在一些实施例中，所述加强块包括与所述第一部分相连的第二部分，所述第二部分位于所述第一部分与所述第一侧壁之间，所述第二部分包括所述第二端面，所述第二部分沿第一方向的长度大于所述第一部分沿所述第一方向的长度，所述第一方向为所述第一电池单体和所述第二电池单体的排列方向。
这样，第二部分沿第一方向的长度上相较于第一部分多余的部分，可以与第一电池单体的第一壁或者第二电池单体的第一壁相抵接，避免加强块沿垂直于第一侧壁的第三方向偏移，使得加强块在第三方向上相对固定。
在一些实施例中，所述多个电池单体中的第三电池单体与所述第一电池单体沿第二方向排列，所述多个电池单体中的第四电池单体与所述第二电池单体沿所述第二方向排列，所述第二方向垂直于所述第一箱体部的底壁，所述第三电池单体与所述第四电池单体相邻，所述第三电池单体和所述第四电池单体之间通过所述汇流部件连接。
在一些实施例中，所述第三电池单体和所述第四电池单体之间夹持 有第二加强板。将第一加强板和第二加强板设置为相互独立的两个部件，可以避让在第一电池单体与第三电池单体之间以及第二电池单体与第四电池单体之间设置的其他部件。
在一些实施例中，所述第二部分包括延伸部，所述延伸部位于所述汇流部件与所述第一侧壁之间，且所述延伸部与所述汇流部件之间具有间隙。
由于第三电池单体和第四电池单体之间设置有同一个汇流部件，因此，加强块无法直接与第二加强板相抵接，因此，该加强块的第二部分可以包括延伸部，安装时，将该延伸部***汇流部件与第一侧壁之间，延伸部与第一侧壁相抵接，而与汇流部件之间具有间隙，这样，在第一侧壁受到挤压或者碰撞时，该延伸部可以加强第一侧壁的强度，延伸部与汇流部件之间的间隙也可以避免第一侧壁发生变形时之间挤压到汇流部件，保证汇流部件的安全，以提高电池单体和电池的安全性。
在一些实施例中，所述第一电池单体与所述第三电池单体之间，以及所述第二电池单体与所述第四电池单体之间均设置有热管理部件，以调节电池单体的温度。
在一些实施例中，所述多个电池单体中的第五电池单体与所述第一电池单体沿第三方向排列，所述多个电池单体中的第六电池单体与所述第二电池单体沿所述第三方向排列，所述第三方向垂直于所述第一侧壁，所述第五电池单体的第一壁和所述第六电池单体的第一壁朝向所述第一箱体部的第二侧壁，所述第二侧壁与所述第一侧壁相对设置，所述第一加强板设置于所述第一电池单体和所述第二电池单体之间以及所述第五电池单体和所述第六电池单体之间，所述第一加强板的沿所述第三方向的两端均设置有所述加强块。
在第一电池单体和第二电池单体之间以及第五电池单体和第六电池 单体之间设置有同一个第一加强板，该第一加强板与第一侧壁之间设置有加强块，第一加强板与第二侧壁之间同样设置有加强块，这样可以使得在第三方向上，第一侧壁和第二侧壁之间设置有两个加强块和第一加强板，结构对称，便于安装也提高了电池的强度，保证第三方向上两列电池单体的第一壁的安全，进而提高了电池的安全性。

因此，本申请实施例提供了一种电池，电池的箱体内设置有多个电池单体，电池单体的第一壁上设置有电极端子，该第一壁朝向箱体的第一侧壁设置；该电池还包括多个汇流部件，用于连接多个电池单体的电极端子；该电池还包括第一加强板，该第一加强板设置于多个电池单体中相邻的第一电池单体和第二电池单体之间，第一加强板与第一电池单体的第二壁附接，该第二壁与第一电池单体的第一壁相交；该电池还包括加强块，该加强块具有相对设置第一端面和第二端面。该加强块的第一端面抵接于第一加强板，第二端面抵接于第一侧壁，以使第一侧壁与汇流部件之间具有间隙，这样，在电池受到挤压或者碰撞时，第一侧壁受到的力会直接作用于与第一侧壁抵接的加强块，并通过该加强块将该作用力进一步传输至第一加强板，一方面不会使该第一侧壁受到的力直接作用于电池单体的第 一壁，也就不会影响该第一壁上设置的电极端子以及汇流部件，避免电池单体发生热失控，提高了电池的安全性；另一方面也提高了电池的箱体的强度，使得该电池的箱体不易损坏，进一步提高电池的安全。
本申请实施例描述的技术方案均适用于各种使用电池的用电设备。
用电设备可以是车辆、手机、便携式设备、笔记本电脑、轮船、航天器、电动玩具和电动工具等等。车辆可以是燃油汽车、燃气汽车或新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等；航天器包括飞机、火箭、航天飞机和宇宙飞船等等；电动玩具包括固定式或移动式的电动玩具，例如，游戏机、电动汽车玩具、电动轮船玩具和电动飞机玩具等等；电动工具包括金属切削电动工具、研磨电动工具、装配电动工具和铁道用电动工具，例如，电钻、电动砂轮机、电动扳手、电动螺丝刀、电锤、冲击电钻、混凝土振动器和电刨等等。本申请实施例对上述用电设备不做特殊限制。
以下实施例为了方便说明，以用电设备为车辆为例进行说明。
例如，如图1所示，为本申请一个实施例的一种车辆1的结构示意图，车辆1可以为燃油汽车、燃气汽车或新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等。车辆1的内部可以设置马达40，控制器30以及电池10，控制器30用来控制电池10为马达40的供电。例如，在车辆1的底部或车头或车尾可以设置电池10。电池10可以用于车辆1的供电，例如，电池10可以作为车辆1的操作电源，用于车辆1的电路***，例如，用于车辆1的启动、导航和运行时的工作用电需求。在本申请的另一实施例中，电池10不仅仅可以作为车辆1的操作电源，还可以作为车辆1的驱动电源，替代或部分地替代燃油或天然气为车辆1提供驱动动力。
图2示出了本申请一个实施例的一种电池10的结构示意图，如图2所示，本申请实施例的电池10包括：多个电池单体20和箱体11。其中，箱体11内部为中空结构，多个电池单体20容纳于箱体11内。图2示出了本申请实施例的箱体11的一种可能的实现方式，如图2所示，箱体11可以包括两部分，这里分别称为第一箱体部111和第二箱体部112，第一 箱体部111和第二箱体部112扣合在一起。第一箱体部111和第二箱体部112的形状可以根据电池单体20组合的形状而定，第一箱体部111和第二箱体部112中至少一个具有一个开口。例如，如图2所示，第一箱体部111和第二箱体部112中可以仅有一个为具有开口的中空长方体，而另一个为板状，以盖合开口。例如，这里以第一箱体部111为中空长方体且具有一个开口1113，而第二箱体部112为板状为例，那么第二箱体部112盖合在第一箱体部111的开口1113处以形成具有封闭腔室的箱体11，该腔室可以用于容纳多个电池单体20。多个电池单体20相互并联或串联或混联组合后置于第一箱体部111和第二箱体部112扣合后形成的箱体11内。
再例如，不同于图2所示，该第一箱体部111和第二箱体部112均可以为中空长方体且各自有一个面为开口面，第一箱体部111的开口和第二箱体部112的开口相对设置，并且第一箱体部111和第二箱体部112相互扣合形成具有封闭腔室的箱体11。
根据不同的电力需求，电池10中的电池单体20的数量可以设置为任意数值。多个电池单体20可通过串联、并联或混联的方式连接以实现较大的容量或功率。由于每个电池10中包括的电池单体20的数量可能较多，为了便于安装，还可以将电池单体20分组设置，每组电池单体20组成电池模块。电池模块中包括的电池单体20的数量不限，可以根据需求设置。电池可以包括多个电池模块，这些电池模块可通过串联、并联或混联的方式进行连接。
可选地，电池10还可以包括其他结构，在此不再一一赘述。例如，该电池10还可以包括汇流部件12，汇流部件12用于实现多个电池单体20之间的电连接，例如并联或串联或混联。具体地，汇流部件12可通过连接电池单体20的电极端子211实现电池单体20之间的电连接。进一步地，汇流部件12可通过焊接固定于电池单体20的电极端子211。多个电池单体20的电能可进一步通过导电机构穿过箱体11而引出。
下面将结合附图，对本申请实施例的电池10进行详细描述。图3示出了本申请实施例的电池10的局部分解结构示意图。如图2至图3所 示，本申请实施例的电池10具体包括：第一箱体部111，该第一箱体部111为具有开口1113的中空结构，该第一箱体部111包括与该开口1113相邻的第一侧壁1111；多个电池单体20，容纳于该中空结构，该电池单体20的第一壁21上设置有电极端子211，该第一壁21为该电池单体20的朝向该第一侧壁1111的壁；多个汇流部件12，用于电连接该多个电池单体20的电极端子211；第一加强板131，设置于该多个电池单体20中相邻的第一电池单体201和第二电池单体202之间，该第一加强板131与该第一电池单体201的第二壁22附接，该第二壁22与该第一电池单体201的第一壁21相交；加强块14，该加强块14具有相对设置第一端面141和第二端面142，该第一端面141抵接于该第一加强板131，该第二端面142抵接于该第一侧壁1111，以使该第一侧壁1111与该汇流部件12之间具有间隙。
因此，本申请实施例的电池10中设置有第一加强板131和加强块14，该加强块14的第一端面141抵接于第一加强板131，第二端面142抵接于第一侧壁1111，以使第一侧壁1111与汇流部件12之间具有间隙，这样，在电池10受到挤压或者碰撞时，第一侧壁1111受到的力会直接作用于与第一侧壁1111抵接的加强块14，并通过该加强块14将该作用力进一步传输至第一加强板131，一方面不会使该第一侧壁1111受到的力直接作用于电池单体20的第一壁21，例如，第一侧壁1111受到的力不会直接作用于第一电池单体201的第一壁21和第二电池单体201的第一壁21，也就不会影响第一壁21上设置的电极端子211以及汇流部件12，避免电池单体20发生热失控，进而提高了电池10的安全性；另一方面也提高了电池10的箱体11的强度，使得该电池10的箱体11不易损坏，进一步提高电池10的安全。
应理解，本申请实施例中的电池单体20可以为任意多面体结构，该电池单体20的第一壁21可以为电池单体20的任意一个壁，并且该第一壁21上设置有电极端子211。例如，该电池单体20可以为六面体结构，该第一壁21可以为电池单体20的面积最小的或者最大的壁。再例如，如图2至图3所示，下文中以该电池单体20为长方体为例进行说 明，该第一壁21可以为电池单体20的任意一个壁，图中以第一壁21为电池单体20的面积最小的壁为例，但本申请实施例并不限于此。
应理解，本申请实施例电池单体20的电极端子211可以用于实现多个电极单体20之间的电连接。具体地，电池单体20的内部可以包括电极组件，电极组件包括极耳和主体部，其中，电极组件的极耳可以包括正极极耳和负极极耳，正极极耳可以由正极极片上未涂覆正极活性物质层的部分层叠形成，负极极耳可以由负极极片上未涂覆负极活性物质层的部分层叠形成，主体部可以由正极极片上涂覆有正极活性物质层的部分和负极极片上涂覆有负极活性物质层的部分层叠形成或者卷绕形成。电极端子211用于与电极组件电连接，以输出电池单体的电能。每个电池单体20的电极端子211可以包括正极电极端子和负极电极端子，正极电极端子用于与正极极耳电连接，负极电极端子用于与负极极耳电连接。正极电极端子与正极极耳可以直接连接，也可以间接连接，负极电极端子与负极极耳可以直接连接，也可以间接连接。示例性的，正极电极端子通过一个连接构件与正极极耳电连接，负极电极端子通过一个连接构件与负极极耳电连接。
可选地，该电池单体20的第一壁21上还可以设置有泄压机构212，泄压机构212是泄放电池单体20内部的压力的部件。具体地，在电池单体20内部的压力或温度达到阈值时，泄压机构212致动以泄放电池单体20内部的压力。例如，该泄压结构212上可以设置有刻痕槽，在电池单体20内部的压力或温度达到阈值时，泄压结构212沿刻痕槽破裂，从而释放内部压力。
本申请中所提到的“致动”是指泄压机构212产生动作，从而使得电池单体20的内部压力及温度得以被泄放。泄压机构212产生的动作可以包括但不限于：泄压机构212中的至少一部分破裂、被撕裂或者熔化，等等。泄压机构212在致动后，电池单体20内部的高温高压物质作为排放物会从泄压机构212向外排出。以此方式能够在可控压力或温度的情况下使电池单体20发生泄压，从而避免潜在的更严重的事故发生。
本申请中所提到的来自电池单体20的排放物包括但不限于：电解 液、被溶解或***的正负极极片、隔离膜的碎片、反应产生的高温高压气体、火焰等。
该预定阈值可以根据设计需求不同而进行调整。例如，该预定阈值可取决于电池单体20中的正极极片、负极极片、电解液和隔离膜中一种或几种的材料。泄压机构212可以采用诸如对压力敏感或温度敏感的元件或部件，即，当电池单体20的内部压力或温度达到预定阈值时，泄压机构212致动，从而形成可供内部压力或温度泄放的通道。
电池单体20上的泄压机构212对电池10的安全性有着重要影响。例如，当电池单体20发生短路、过充等现象时，可能会导致电池单体20内部发生热失控从而压力或温度骤升。这种情况下通过泄压机构212致动可以将内部压力及温度向外释放，以防止电池单体20***、起火，进而保证电池10的安全性。因此，在泄压机构212设置在第一壁21的情况下，由于该第一壁21朝向箱体11的第一侧壁1111设置，第一侧壁1111受到挤压或者碰撞时，加强块14可以避免第一侧壁1111受到的力直接作用于第一壁21，既可以避免第一壁21上设置的电极端子211以及汇流部件12受到挤压和碰撞，还可以避免泄压机构212受到挤压和碰撞而发生变形，避免泄压机构212提前失效，进而提高了电池10的安全性。
在本申请实施例中，电池10可以包括多个电池单体20，该多个电池单体20可以呈阵列排列，以提高电池10的能量密度。例如，如图2至图3所示，该多个电池单体20可以包括沿第一方向X排列的多个电池单体20，该第一方向X可以平行于第一侧壁1111且平行于第一箱体部111的底壁。再例如，该多个电池单体20也可以包括沿第二方向Z排列的多个电池单体20，该第二方向Z垂直于第一箱体部111的底壁。再例如，该多个电池单体20也可以包括沿第三方向Y排列的多个电池单体20，第三方向Y垂直于第一侧壁1111。其中，第一方向X、第二方向Z和第三方向Y相互垂直。
应理解，本申请实施例中的第一电池单体201和第二电池单体202可以为任意相邻的两个电池单体20。例如，如图2和图3所示，第一电池单体201和第二电池单体202沿第一方向X排列，第一加强板131垂直于 第一方向X，第一方向X平行于第一侧壁1111且平行于第一箱体部111的底壁。也就是说，该第一电池单体201和第二电池单体202为第一方向X上排列的多个电池单体20中任意两个相邻的电池单体20，第一方向X上排列有至少3个电池单体20时，则任意两个相邻的电池单体20之间均可以设置第一加强板131，本申请实施例并不限于此。
其中，第一加强板131垂直于第一方向X可以指：该第一加强板131的面积最大的表面所在的平面垂直于第一方向，即该第一加强板131的面积最大的表面所在平面垂直于第一箱体部111的底壁和第一侧壁1111，同时，与该第一加强板131附接的第一电池单体201的第二壁22和第二电池单体202的第二壁也均垂直于第一箱体部111的底壁和第一侧壁1111。这样，在第一电池单体201和第二电池单体202之间夹持第一加强板131并安装于第一箱体部111内的情况下，便于通过开口1113安装加强块14。
图4为本申请实施例的电池10的局部放大图，具体地，该图4为图2中区域A的放大图。如图4所示，第一电池单体201的电极端子211和第二电池单体202的电极端子211之间不通过汇流部件12连接。具体地，考虑到多个电池单体20之间需要通过汇流部件12实现电连接，若第一电池单体201和第二电池单体202之间不通过同一个汇流部件12相连，那么这两个电池单体20之间则具有足够的空间设置加强块14，以使得该加强块14的第一端面141与第一加强板131抵接，第二端面142与第一侧壁1111抵接。
在本申请实施例中，第一端面141以及第一加强板131的与第一端面141抵接的表面相互平行且均相对于第一电池单体201的第一壁21倾斜，第一端面141的靠近开口1113的一边远离第一侧壁1111，且第一端面141的远离开口1113的一边靠近第一侧壁1111。具体地，图5示出了本申请实施例的加强块14的示意图，如图2至图5所示，该加强块14的第一端面141与第一加强板131抵接，并且第一加强板131与第一端面141相抵接的表面与第一端面141是相互平行的，使得二者可以紧密贴合；并且，第一端面141倾斜设置，在安装时，可以通过倾斜的第一端面 141，将加强块14自开口1113处***第一加强块131与第一侧壁1111之间，进而实现加强块14与第一侧壁1111之间紧密附接以及加强块14与第一加强板131之间的紧密附接。
如图2至图5所示，加强块14包括第一部分144，第一部分144包括第一端面141，第一部分144设置于第一电池单体201和第二电池单体202之间，以使得该第一部分144可以夹持在第一电池单体201和第二电池单体202之间，使得加强块14在第一方向X上相对固定，避免加强块14在第一方向X上的偏移。
如图2至图5所示，加强块14包括与第一部分144相连的第二部分145，第二部分145位于第一部分144与第一侧壁1111之间，第二部分145包括第二端面142，第二部分145沿第一方向X的长度大于第一部分144沿第一方向X的长度，第一方向X为第一电池单体201和第二电池单体202的排列方向，以使得第二部分145沿第一方向X的长度上相较于第一部分144多余的部分，可以与第一电池单体201的第一壁21或者第二电池单体202的第一壁21相抵接，避免加强块14沿垂直于第一侧壁1111的第三方向Y偏移，使得加强块14在第三方向Y上相对固定。
如图2至图5所示，该加强块14还包括：第三端面143，该第三端面143连接第一端面141和第二端面142，第三端面143抵接于第二箱体部112，以使得该加强块14在第二方向Z上相对固定，避免加强块14在第二方向Z上的偏移，该第二方向Z垂直于第一箱体部111的底壁。
应理解，加强块14的第一端面141、第二端面142和第三端面143分别抵接不同部件，使得该加强块14相对第一方向X、第二方向Z和第三方向Y均相对固定，保证在电池10的使用过程中，加强块14不会发生偏移，也就保证在第一侧壁1111受到挤压和碰撞时，受到的外力可以通过加强块14顺利传输至第一加强板131，保证电池10的强度和安全性。
如图2至图5所示，多个电池单体20中的第三电池单体203与第一电池单体201沿第二方向Z排列，多个电池单体20中的第四电池单体204与第二电池单体202沿第二方向Z排列，第二方向Z垂直于第一箱体部111的底壁，第三电池单体203与第四电池单体204相邻，第三电池单 体203和第四电池单体204之间通过汇流部件12连接。在按照如图所示的方式设置多个汇流部件12以连接多个电池单体20时，第三电池单体203和第四电池单体204之间通常可以通过同一个汇流部件12实现电连接。
可选地，如图2至图5所示，第一电池单体201与第三电池单体203之间，以及第二电池单体202与第四电池单体204之间均设置有热管理部件15，以调节电池单体20的温度，例如，该热管理部件15可以容纳流体以给多个电池单体20调节温度。这里的流体可以是液体或气体，调节温度可以是指给多个电池单体20加热或者冷却。在给电池单体20冷却或降温的情况下，该热管理部件15用于容纳冷却流体以给多个电池单体20降低温度；另外，热管理部件15也可以用于加热以给多个电池单体20升温，本申请实施例对此并不限定。可选的，上述流体可以是循环流动的，以达到更好的温度调节的效果。可选的，流体可以为水、水和乙二醇的混合液或者空气等。
可选地，本申请实施例的热管理部件15上还可以设置其他部件，例如，还可以在热管理部件15的表面设置结构胶，以使固定设置在热管理部件15表面的电池单体20，尤其是多个电池单体20的面积最大的壁朝向热管理部件15时，设置结构胶能够极大的增加电池单体10的稳定性，进而提高了电池10的强度和稳定性。或者，也可以将热管理部件15替换为其他部件，例如，将热管理部件15替换为结构胶等，本申请实施例并不限于此。
如图2至图5所示，第三电池单体203和第四电池单体204之间夹持有第二加强板132。在第一电池单体201与第三电池单体203之间，以及第二电池单体202与第四电池单体204之间均设置有热管理部件15，或者设置有其他部件的情况下，将第一加强板131和第二加强板132设置为相互独立的两个部件，可以避让在第一电池单体201与第三电池单体203之间以及第二电池单体202与第四电池单体204之间的热管理部件15或者其他部件。在第一电池单体201与第三电池单体203之间以及第二电池单体202与第四电池单体204之间未设置有其他部件时，第一加强板131 和第二加强板132可以设置为相互独立的两个部件，或者，也可以设置为同一个加强板，即第二加强板132为第一加强板131。将第一加强板131和第二加强板132设置为相互独立的两个部件可以便于组装，例如，可以将第一电池单体201、第二电池单体202以及夹持的第一加强板131相对固定，另外，将第三电池单体203、第四电池单体204以及夹持的第二加强板132相对固定，结构相对简单；而将第一加强板131和第二加强板132设置为同一个加强板，可以节省设置的加强板的个数，降低成本。
如图2至图5所示，第二部分145包括延伸部1451，延伸部1451位于汇流部件12与第一侧壁1111之间，且延伸部1451与汇流部件12之间具有间隙。由于第三电池单体203和第四电池单体204之间设置有同一个汇流部件12，因此，加强块14无法直接与第二加强板132相抵接，因此，该加强块14的第二部分145可以包括延伸部1451，安装时，将该延伸部1451***汇流部件12与第一侧壁1111之间，延伸部1451与第一侧壁111相抵接，而与汇流部件12之间具有间隙，这样，在第一侧壁1111受到挤压或者碰撞时，该延伸部1451可以加强第一侧壁1111的强度，延伸部1451与汇流部件12之间的间隙也可以避免第一侧壁1111发生变形时之间挤压到汇流部件12，保证汇流部件12的安全，以提高电池单体20和电池10的安全性。
图6示出了本申请实施例的电池10的俯视示意图，具体地，图6可以为图3所示的电池10在安装之后的俯视示意图。如图6所示，多个电池单体20中的第五电池单体205与第一电池单体201沿第三方向Y排列，多个电池单体20中的第六电池单体206与第二电池单体202沿第三方向Y排列，第三方向Y垂直于第一侧壁1111，第五电池单体205的第一壁21和第六电池单体206的第一壁21朝向第一箱体部111的第二侧壁1112，第二侧壁与第一侧壁1111相对设置，第一加强板131设置于第一电池单体201和第二电池单体202之间以及第五电池单体205和第六电池单体206之间，第一加强板131的沿第三方向Y的两端均设置有加强块14。
如图6所示，第一箱体部111可以具有相对设置的第一侧壁111和 第二侧壁1112，并且，在第三方向Y上，可以设置有多列电池单体20，例如，可以设置有两列个电池单体20，其中，一列电池单体20中的第五电池单体205与另一列电池单体20中的第一电池单体201相邻，一列电池单体20中的第六电池单体206与另一列电池单体20中的第二电池单体202相邻。
第一电池单体201的第一壁21和第二电池单体202的第一壁21朝向第一侧壁1111，第一电池单体201的第二壁22与第二电池单体202的第二壁22之间夹持第一加强板131，并且第一加强板131与第一侧壁1111之间设置有加强块14；第五电池单体205的第一壁21和第六电池单体206的第一壁21朝向第二侧壁1112，第五电池单体205的第二壁22和第六电池单体206的第二壁22之间也夹持第一加强板131，并且第一加强板131与第二侧壁11112之间也设置有加强块14。这样，在第三方向Y上，第一侧壁1111和第二侧壁1112之间设置有两个加强块14和第一加强板131，结构对称，便于安装也提高了电池10的强度，保证第三方向Y上两列电池单体20的第一壁21的安全，进而提高了电池10的安全性。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
