为了说明本申请所提供的技术方案，以下结合具体附图及实施例进行详细说明。
随着新能源的快速发展，电池的应用越加广泛。而为了保证电池在应用中具有足够的能量密度，如图1所示，通常将多个电芯单元21进行串联或者并联形成电芯组件20，电芯单元21是构成电池的最小能量单元，实现化学能和电能转换。电芯单元21主要由正极片和负极片卷绕或层叠放置形成，并且通常在正极片与负极片之间设有隔膜。正极片和负极片具有活性物质的部分构成电芯单元21的主体部，正极片和负极片不具有活性物质的部分各自构成极耳210。在电池的充放电过程中，正极活性物质和负极活性物质与电解液发生反应，极耳210为形成电流回路提供了连接基础。多个电芯单元21沿同一方向层叠在一起，两侧加上端板22，并通过绑带23进行绑定，为了保证电芯单元21不会轻易被端板22挤压致损，在端板22与电芯单元21贴合的一侧可以加上一层缓冲垫。
汇流排组件用于实现电芯组件20中多个电芯单元21之间的电性连接，汇流排组件包括用于起到电性连接作用的汇流排，及用于支撑固定汇流排的汇流排支架，汇流排支架采用绝缘材料制成，通过汇流排可以将多个电芯单元21的极耳210连接在一起，连接形式可以为串联或者并联。
但是，申请人注意到，目前的汇流排组件通常设计为穿孔形式，电芯组件20正对汇流排组件进行装配，每个电芯单元21的极耳210需要在装配过程中经过穿孔，后与汇流排进行焊接，在装配人员实际装配过程中，由于电芯组件20与汇流排组件保持正对，视线会受到装配部件的阻隔，无法确认每个电芯单元21的极耳210均能准确地经过穿孔，尤其是当电芯单元21的数量较多时，装配的困难会大幅提升。
为了降低汇流排组件与电芯组件20装配时的难度，申请人发现，可以将汇流排组件设计为导向缺口的形式，即在汇流排支架上开设多个缺口，每个缺口均能保证电芯组件20的极耳210顺利***。
在采用这样的汇流排组件后，电芯组件20不再正对汇流排组件进行装配，装配人员只需将电芯组件20中每个电芯单元21的极耳210***汇流排支架的缺口中，而后进行极耳210与汇流排部件之间的焊接，即可完成汇流排组件与电芯组件20之间的装配，由于在装配过程中，电芯组件20中每个电芯单元21的极耳210与汇流排组件是相互错开的，装配人员可以时刻观察到，每个电芯单元21的极耳210逐渐***汇流排支架上的缺口的过程，并且可以直接进行偏移调整，因此，装配过程中的可视化程度更高，降低了装配难度。
本申请实施例提供的汇流排组件可以但不限用于锂硫电池、钠离子电池或镁离子电池。
如图2和图3所示，本申请实施例提供的汇流排组件10包括汇流排支架11和汇流排12，汇流排支架11设置有沿预设方向（图3中箭头X所示方向）交替分布的多个抵接部111和多个第一缺口112，每个第一缺口112用于供电芯组件20的极耳210***；汇流排12与至少部分抵接部111连接、用于与***第一缺口112的极耳210电性连接。
汇流排支架11是用于支撑固定汇流排12的部件，汇流排12是用于电性连接电芯组件20的极耳210的部件。汇流排支架11设置有沿预设方向交替分布的多个抵接部111和多个第一缺口112，是指汇流排支架11上设置的多个第一缺口112沿同一方向分布，两个相邻的第一缺口112之间具有间隔，与每个第一缺口112相邻的是一个抵接部111，第一缺口112即用于供电芯组件20的极耳210***的导向缺口。
通过汇流排支架11上设置的多个第一缺口112，可以在与电芯组件20装配时，起到为电芯组件20的极耳210导向的作用，使电芯组件20中每个电芯单元21的极耳210能够顺利地***第一缺口112，并与连接在抵接部111上的汇流排12电性连接，在电芯组件20的极耳210***第一缺口112的过程中，装配人员可以明确地观察到电芯组件20的极耳210与第一缺口112的配对情况，及二者之间的偏移程度，从而使得汇流排组件10与电芯组件20的装配过程的可视化程度更高，有利于装配人员的实时调整，降低了装配过程中的难度。
此处汇流排12可以用于串联电芯组件20中多个电芯单元21的场合，也可以用于并联电芯组件20中多个电芯单元21的场合，下面以汇流排12用于串联电芯组件20中多个电芯单元21的场合为例，说明汇流排组件10的具体形式。
在本申请的一些实施例中，可选地，汇流排12包括多个相互分隔的汇流排本体120（图4和图5所示），每两个相邻的汇流排本体120之间间隔一个抵接部111，每个汇流排本体120用于电性连接***相邻的第一缺口112的极耳210。
汇流排本体120指形成汇流排12的单个实体，多个汇流排本体120相互分隔指多个汇流排本体120处于相互绝缘的情况，彼此之间没有电性连接在一起。
通过使多个汇流排本体120之间相互分隔，可以使每个汇流排本体120在电性连接两个相邻的电芯单元21中，其中一个电芯单元21的正极耳和另外一个电芯单元21的负极耳的同时，确保电芯组件20中多个电芯单元21一路串联下去，从而实现电芯组件20中多个电芯单元21的串联。
这里的电芯组件20中，多个电芯单元21的极耳210呈一正一负的形式设置，即两个相邻的电芯单元21反向设置，使得其中一个电芯单元21的正极耳210与另外一个电芯单元21的负极耳210位于电芯组件20的同一侧。
在本申请的一些实施例中，可选地，在预设方向上位于最外侧的一个汇流排本体120上设置有接线部121（即图4所示的汇流排本体），接线部121自该汇流排本体120向远离其他汇流排本体120的方向延伸，汇流排支架11上设置有与接线部121相扣合的定位槽113。
接线部121指汇流排本体120上设置的用于与外部电性连接的部分，由于此处的汇流排本体120用于串联电芯组件20中多个电芯单元21的场合，因此，接线部121设置在预设方向上位于最外侧的一个汇流排本体120上，定位槽113指汇流排支架11上设置的与接线部121相扣合的凹槽结构。
通过在预设方向上位于最外侧的一个汇流排本体120上设置接线部121，可以为电芯组件20与外部的电性连接提供连接基础和足够的连接空间。
在本申请的一些实施例中，可选地，接线部121上设置有通孔122。
通孔122指接线部121上设置的穿孔，通过在接线部121上设置通孔122，可以有利于外部连接部件的定位。
在本申请的一些实施例中，可选地，每个汇流排本体120上还设置有卡接部123，每个汇流排本体120的卡接部123自该汇流排本体120向预设方向（图3中箭头X所示方向）弯折延伸，每个汇流排本体120的卡接部123上设置有定位缺口124，汇流排支架11上设置有***定位缺口124的卡块114。
卡接部123指汇流排本体120上与汇流排支架11进行卡接的部分，定位缺口124指汇流排本体120上设置的缺口结构。
通过卡接部123的设置，可以实现每个汇流排本体120与汇流排支架11之间的卡接，有利于汇流排本体120在汇流排支架11上的定位，在汇流排本体120与汇流排支架11卡接时，汇流排支架11上的卡块114***汇流排本体120上的定位缺口124，从而将汇流排本体120卡在汇流排支架11上。
在本申请的一些实施例中，可选地，汇流排支架11上设置有与多个汇流排本体120一一对应的多个热熔柱115，每个汇流排本体120上设置有环绕对应的热熔柱115的凹槽125，每个热熔柱115通过热熔固接对应的汇流排本体120与汇流排支架11。
热熔柱115是汇流排支架11上设置的柱体，可以通过热熔成蘑菇状，对环绕热熔柱115设置的汇流排本体120起到固定作用。
通过对热熔柱115进行热熔，使热熔柱115的头部形成蘑菇状，从而可以防止环绕热熔柱115设置的汇流排本体120从汇流排支架11上脱离，与卡块114共同起到固定连接汇流排本体120与汇流排支架11上的作用。
其中，卡块114可以防止汇流排本体120从图3图面的下方脱离，热熔柱115可以防止汇流排本体120从图3图面的上方脱离，同时，两者均能防止回流本体120从图3图面的左右方向脱离，因此，起到了将汇流排本体120牢固地固定在回流排支架11上的作用。
此处也可以在汇流排本体120上设置环绕热熔柱115的穿孔结构，同样可以在对热熔柱115进行热熔后，固定连接汇流排本体120与汇流排支架11。
在连接汇流排本体120与汇流排支架11时，将汇流排本体120沿正对汇流排支架11的方向贴附在汇流排支架11上，使汇流排支架11上的卡块114***汇流排本体120上的定位缺口124，并使汇流排本体120上的凹槽125环绕汇流排支架11上的热熔柱115，然后对热熔柱115进行热熔，即可将汇流排本体120固定在汇流排支架11上。
在本申请的一些实施例中，可选地，汇流排支架11上还设置有沿预设方向分布的多个挡片116，每个挡片116位于两个相邻的汇流排本体120的卡接部123之间。
通过挡片116可以对两个相邻的汇流排本体120起到绝缘阻隔的作用，以确保两个相邻的汇流排本体120处于绝缘状态。
在进行电芯组件20与汇流排组件10的装配时，如图6所示，可以先将汇流排组件10安装至支撑工装30上，然后将电芯组件20落下，直至电芯组件20的极耳210***汇流排支架11上的第一缺口112。
而为了便于将汇流排组件10安装至支撑工装30上，在本申请的一些实施例中，可选地，汇流排支架11还设置有沿预设方向交替分布的多个导向部117和多个第二缺口118，多个第二缺口118与多个第一缺口112位于汇流排支架11的相对两侧，多个导向部117向远离汇流排12的一侧凸起。
汇流排支架11还设置有沿预设方向交替分布的多个导向部117和多个第二缺口118，是指汇流排支架11上设置的多个第二缺口118沿同一方向分布，两个相邻的第二缺口118之间具有间隔，与每个第二缺口118相邻的是一个导向部117，第二缺口118即用于为汇流排组件10安装至支撑工装上时提供导向的缺口，多个第二缺口118的分布方向与多个第一缺口112的分布方向相同，同样是沿图3中箭头X所示方向分布。
多个第二缺口118与多个第一缺口112位于汇流排支架11的相对两侧，指第二缺口118的开设方向与第一缺口112的开设方向相反，如图3所示，第一缺口112自图3中汇流排支架11的顶部向底部开设，第二缺口118自图3中汇流排支架11的底部向顶部开设。
通过汇流排12上设置的第二缺口118和导向部117，如图7和图8所示，可以为汇流排组件10安装至支撑工装10上提供导向作用，从而有利于将汇流排组件10轻松安装至支撑工装30上，支撑工装30上的支撑柱31可以沿第二缺口118***。
另外，支撑工装30上设置的支撑柱31，可以在焊接电芯组件20的极耳210的过程中，承受来自焊枪焊嘴的压力。
如图7所示，支撑工装30为一块矩形平板，支撑工装30的相对两侧设置有凹陷区域，用于定位待安装的汇流排支架11，同时，支撑工装30的凹陷区域设置有一排支撑柱31，支撑柱31可以在汇流排支架11安装至支撑工装30时，沿两个相邻的导向部117之间的第二缺口118***，直至支撑柱31抵接在汇流排支架11的抵接部111上，然后再进行电芯组件20与汇流排组件10的装配，待极耳210焊接完成后，将装配好的电芯组件20与汇流排组件10从支撑工装30上取出即可。
图9示出了电芯组件20的极耳210逐渐落下并***汇流排支架11的结构，图10和图11则分别示出了电芯组件20的极耳210与汇流排本体120完成焊接后的主视结构和俯视结构，图12则示出了在汇流排支架11与电芯单元21之间存在的空间（矩形框C所示区域），该空间为装配汇流排组件10后的电芯组件20在从支撑工装30上取出时，支撑工装30上的支撑柱31所占据的空间，以便在电芯组件20的极耳210与汇流排本体120的焊接过程中，通过支撑柱31承受来自焊枪焊嘴的压力。
在本申请的一些实施例中，可选地，汇流排支架11靠近多个第二缺口118的一侧设置有定位孔119（图2所示）。
定位孔119用于与支撑工装30上的定位柱32相配合，以在将汇流排组件10安装至支撑工装30上时，对汇流排支架11起到定位的作用。
在本申请的一些实施例中，汇流排组件10包括汇流排支架11和汇流排12，汇流排支架11设置有沿预设方向交替分布的多个抵接部111和多个第一缺口112，每个第一缺口112用于供电芯组件20的极耳210***，汇流排支架11还设置有沿预设方向交替分布的多个导向部117和多个第二缺口118，多个第二缺口118与多个第一缺口112位于汇流排支架11的相对两侧，多个导向部117向远离汇流排12的一侧凸起，汇流排12包括多个相互分隔的汇流排本体120，每个汇流排本体120与其中一个抵接部111连接，每两个汇流排本体120之间间隔一个抵接部111，在预设方向上位于最外侧的一个汇流排本体120上设置有接线部121，每个汇流排本体120与汇流排支架11通过热熔进行固定。
本申请实施例还提供一种电池，包括电芯组件20，以及上述实施例中的汇流排组件10，汇流排组件10有两个且相对设置在电芯组件20的两侧，电芯组件20一侧的极耳210***其中一个汇流排组件10的汇流排支架11上的第一缺口112、并与该汇流排组件10的汇流排12电性连接，电芯组件20另一侧的极耳210***另一个汇流排组件10的汇流排支架11上的第一缺口112、并与该汇流排组件10的汇流排12电性连接。
在电芯组件20的极耳210***第一缺口112的过程中，装配人员可以明确地观察到电芯组件20的极耳210与第一缺口112的配对情况，及二者之间的偏移程度，从而使得汇流排组件10与电芯组件20的装配过程的可视化程度更高，有利于装配人员的实时调整，降低了装配过程中的难度。
本申请实施例还提供一种用电装置，用电装置使用上述实施例中的电池作为电源。本申请实施例提供的用电装置可以为但不限于手机、平板、笔记本电脑、电动玩具、电动工具、电瓶车、电动汽车、轮船、航天器等等。其中，电动玩具可以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，航天器可以包括飞机、火箭、航天飞机和宇宙飞船等等。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
