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，下面将对本公开的实施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。
结合图1和图2所示，电池包包括箱体3以及设置在箱体3的单体电池组件，箱体3可由铝、铝合金或其他金属材料制成，箱体3内具有容置腔。在一些实施例中，箱体3为顶部敞开的箱体3结构，并包括上箱盖，上箱盖的尺寸与箱体3顶部的开口的尺寸相当，上箱盖可通过螺栓等固定件固定于开口，从而形成容置腔。同时，为了提高箱体3的密封性，在上箱盖与箱体3之间还可设置密封件。
结合图2和图3所示，本公开实施例提供的电池包包括箱体3和设置于箱体3内的单体电池组件，单体电池组件包括顶盖和设置于所述顶盖上的极柱；其中，所述顶盖和所述箱体3之间设有支撑件4以使极柱和所述箱体之间形成避让部。一方面，支撑件4可以起到缓冲作用，降低极柱受碰撞力的风险；另一方面，避让部可以作为箱体受到碰撞时的变形空间，减少由于箱体变形造成箱体3挤压极柱使极柱损坏的可能性。当箱体发生碰撞时，箱体3可以将受到的碰撞力通过支撑件4传递给顶盖以及顶盖下方的壳体，还可以将碰撞力传导至壳体边缘，使箱体3发生碰撞时不容易损坏单体电池组件内部电极组件，提高了电池包的安全性。
避让部可以为箱体3与极柱之间形成的避让间隙。
在一些具体的实施方式中，支撑件4包括相互连接的上支撑筋411和下支撑筋412，上支撑筋411与顶盖抵接，下支撑筋412与箱体3抵接。一方面，支撑件4可以起到缓冲作用，降低极柱受碰撞力的风险。另一方面，当箱体3发生碰撞时，箱体3可以将受到的碰撞力传递给下支撑筋412，下支撑筋412将力传导至上支撑筋411，上支撑筋411再将力传导至壳体。通过在顶盖和箱体3之间设置支撑件4，可以将碰撞力传导至壳体边缘，不容易损坏单体电池组件内部电极组件，提高了电池包的安全性。
在一些具体的实施方式中，箱体3的容置腔内可容置一个或两个以上的电池模组，电池模组在箱体3内可以沿电池包的长度方向并排设置，也可以沿电池包的宽度方向并排设置，且各电池模组与箱体3固定。
具体地，单体电池组件包括电池模组，电池模组包括多个电池单元和框架结构，其中，电池单元可以为能够重复充放电使用的二次电池，框架结构包括相互连接的端板、侧板、顶板和底板，多个电池单元位于框架结构的内腔，并在该内腔中相互堆叠设置，堆叠方向可为长度方向、宽度方向或高度方向。
如图4所示，电池单元包括电极组件13、顶盖组件和壳体14，其中，壳体14可为六面体形，也可为其他形状，且该壳体14内部形成容纳腔，用于容纳电极组件13和电解液，壳体14的一端开口，使得电极组件13可通过该开口放置于壳体14的容纳腔，且容纳腔内可设置有多个电极组件13，多个电极组件13相互堆叠。其中，壳体14可包括金属材料，例如铝或铝合金等，也可包括绝缘材料，例如塑胶等。
顶盖组件包括顶盖板和两个极柱，顶盖板固定于壳体14的开口，并设置有防爆口，从而将电极组件13和电解液封闭于壳体14的容纳腔，极柱设置于顶盖板，并包括正极柱和负极柱。
结合图2和图3所示，本公开实施例提供的电池包中单体电池组件包括第一电池模组和第二电池模组，第一电池模组和第二电池模组并排设置；第一电池模组包括多个第一电池单元1，多个第一电池单元1沿排列方向依次堆叠，第一电池单元1包括第一顶盖板11和设置于第一顶盖板11上的第一极柱12；第二电池模组包括多个第二电池单元2，多个第二电池单元2沿排列方向依次堆叠，第二电池单元2包括第二顶盖板21和设置于第二顶盖板21上的第二极柱22；第一顶盖板11、第二顶盖板21和箱体3之间设有支撑件4，支撑件4沿排列方向延伸，此时，避让部为第一极柱12、第二极柱22和箱体3之间的避让间隙。
需要说明的是，本实施例所述的排列方向为电池包的长度方向X。支撑件可以是塑料件，也可以是橡胶件。
在一些实施例中，沿电池包的宽度方向Y，第一电池模组和第二电池模组并排设置；沿电池包的长度方向X，多个第一电池单元1依次堆叠，多个第二电池单元2依次堆叠；支撑件4沿长度方向X延伸。
支撑件4包括相互连接的上支撑筋411和下支撑筋412。在一些实施例中，上支撑筋411和下支撑筋412平行。上支撑筋411分别与第一顶盖板11和第二顶盖板21抵接，下支撑筋412与箱体3抵接。一方面，支撑件4可以起到缓冲作用，降低第一极柱12或第二极柱22受Z向力的风险。另一方面，当箱体3发生碰撞时，箱体3可以将受到的碰撞力传递给下支撑筋412，下支撑筋412将力传导至上支撑筋411，上支撑筋411再将力传导至第一电池单元1的壳体14或第二电池单元2的壳体。通过在第一顶盖板11、第二顶盖板21和箱体3之间设置支撑件4，可以将碰撞力传导至第一电池单元1的壳体14边缘或第二电池单元2的壳体边缘，不容易损坏第一电池单元1或第二电池单元2内部电极组件13，提高 了电池包的安全性。
结合图3和图5所示，支撑件4包括第一斜支撑筋421和第二斜支撑筋422；第一斜支撑筋421的顶部和第二斜支撑筋422的顶部分别与上支撑筋411的两侧连接，第一斜支撑筋421的底部和第二斜支撑筋422的底部分别与下支撑筋412的两侧连接；沿从上支撑筋411到下支撑筋412的方向，第一斜支撑筋421朝向第一极柱12倾斜，第一斜支撑筋421靠近上支撑筋411的位置对准第一电池单元1外边缘，有利于将力传导至第一电池单元1的壳体14边缘，不容易损坏第一电池单元1内部电极组件13。沿从上支撑筋411到下支撑筋412的方向，第二斜支撑筋422朝向第二极柱22倾斜，第二斜支撑筋422靠近上支撑筋411的位置对准第二电池单元2外边缘，有利于将力传导至第二电池单元2的壳体边缘，不容易损坏第二电池单元2内部电极组件13。
第一斜支撑筋421和第二斜支撑筋422之间的距离逐渐增大。换言之，上支撑筋411、下支撑筋412、第一斜支撑筋421和第二斜支撑筋422围合成梯形。如图5所示，第一斜支撑筋421竖直方向呈一定角度，该角度使得第一斜支撑筋421和第二斜支撑筋422下面的间距大于上面的间距，这也有利于将力传导至第一电池单元1壳体14边缘，可以降低第一极柱12受Z向力的风险，提高电池包的安全性。在一些实施例中，第一斜支撑筋421与电池包的高度方向Z的夹角为0到90°。第二斜支撑筋422竖直方向呈一定角度，该角度使得第一斜支撑筋421和第二斜支撑筋422下面的间距大于上面的间距，这也有利于将力传导至第二电池单元2壳体14边缘，可以降低第二极柱22受Z向力的风险，提高电池包的安全性。在一些实施例中，第二斜支撑筋422与电池包的高度方向Z的夹角为0到90°。
在一些具体的实施方式中，支撑件4还包括横加强筋431，横加强筋431两端分别与第一斜支撑筋421和第二斜支撑筋422连接，且横加强筋431位于上支撑筋411和下支撑筋412之间。横加强筋431对第一斜支撑筋421和第二斜支撑筋422加强，可以增大第一斜支撑筋421和第二斜支撑筋422被压缩失稳的临界值，可以降低第一极柱12和第二极柱22受Z向力的风险，提高电池包的安全性。
在一些具体的实施方式中，支撑件4还包括第一斜传力筋441和第二斜传力筋442；第一斜传力筋441一端与下支撑筋412连接，另一端形成第一极柱侧向支撑面491；第二斜传力筋442一端与下支撑筋412连接，另一端形成第二极柱侧向支撑面492。当碰撞力大于一定值时，第一斜支撑筋421和第二斜支撑筋422被压缩变形，第一斜支撑筋421向第一极柱12靠近，第二斜支撑筋422向第二极柱22靠近，第一极柱12和第二极柱22分别抵挡第一极柱侧向支撑面491和第二极柱侧向支撑面492的侧向滑动，通过第一斜传力筋441和第二斜传力筋442可以将下支撑筋412拉住，减弱下支撑筋412朝向上支撑筋411压缩的趋势，使下支撑筋412受到的碰撞力向第一电池单元1壳体14和第二电池单元2壳体14传递，可以降低第一极柱12和第二极柱22受Z向力的风险，提高电池包的安全性。
在一些具体的实施方式中，支撑件4还包括第一斜加强筋451和第二斜加强筋452；第一斜加强筋451一端与第一斜支撑筋421连接，另一端与第一斜传力筋441连接；第二斜加强筋452一端与第二斜支撑筋422连接，另一端与第二斜传力筋442连接。第一斜加 强筋451和第一斜传力筋441配合，可以增大支撑件4被压缩失稳的临界值，第二斜加强筋452和第二斜传力筋442配合，可以增大支撑件4被压缩失稳的临界值，可以降低第一极柱12和第二极柱22受Z向力的风险，提高电池包的安全性。
在一些具体的实施方式中，支撑件4包括第一限位筋461和第二限位筋462；第一限位筋461一端与上支撑筋411连接，另一端与第一斜传力筋441连接，使第一斜传力筋441和第一斜加强筋451向第一极柱12方向滑动受到限制，避免支撑件4滑出第一电池单元1或第二单元高度范围。
第二限位筋462一端与上支撑筋411连接，另一端与第二斜传力筋442连接，使第二斜传力筋442和第二斜加强筋452向第二极柱22方向滑动受到限制，避免支撑件4滑出第一电池单元1或第二单元高度范围可，提高了电池包的安全性。
在一些具体的实施方式中，第一限位筋461设有第一弯折部461a，第一弯折部461a受拉可以变长，接近安全展开时，第一极柱侧向支撑面491与第一极柱12接触。在一个实施例中，第一限位筋461厚度比其他筋薄以有利于其展开。第二限位筋462设有第二弯折部462a，第二弯折部462a受拉可以变长，接近安全展开时，第二极柱侧向支撑面492与第二极柱22接触。在一个实施例中，第二限位筋462厚度比其他筋薄以有利于其展开。
在一些具体的实施方式中，支撑件4还包括第一极柱绝缘筋471和第二极柱绝缘筋472；第一极柱绝缘筋471与第一斜传力筋441连接，且第一斜传力筋441位于第一极柱12和箱体3之间，减少箱体3与第一极柱12接触造成短路的可能性；第二极柱绝缘筋472与第二斜传力筋442连接，且第二斜传力筋442位于第二极柱22和箱体3之间，减少箱体3与第二极柱22接触造成短路的可能性。
在一些具体的实施方式中，第一电池单元1和第二电池单元2之间具有间隙5；支撑件4包括凸筋481，凸筋481设置于上支撑筋411的顶部，且凸筋481位于间隙5。凸筋481位于第一电池单元1和第二电池单元2之间，可以避免当支撑件4受力不均时向第一极柱12或第二极柱22滑动，导致支撑件4起不到支撑作用的情况。
