请参考附图1～8，其中，图1为本申请所提供电池包在一种具体实施例中的局部结构示意图；图2为图1中消防流体储存装置的爆炸图；图3为图2中的消防流体储存装置在第一工作状态时的结构示意图；图4为图2中的消防流体储存装置在第二工作状态时的结构示意图；图5为图3中驱动件的结构示意图；图6为图5的另一视角的结构示意图；图7为图3的截面图；图8为图7中Ⅰ部分的局部放大图。
本申请实施例提供一种电池包A，如图1所示，该电池包A包括壳体4，该壳体4具有容纳腔41；电池模组3，放置于该壳体4的容纳腔41，且该电池模组3包括多个电池单元31，电池单元31设置有具有防爆口，该防爆口可设置防爆阀，当该电池单元31发生热失控时，其内部产生高温高压的热流，该防爆阀用于排出热流，以降低该电池单元31燃爆的风险，而当热流从防爆阀排出时，该高温热流可能导致相邻电池单元31发生燃烧。
为了降低某电池单元31热失控时引起相邻电池单元31燃烧的风险，本申请中，在该电池包A中增设喷淋系统，从而降低热流的扩散，提高 电池包A的安全性。其中，该喷淋系统包括喷淋管路2和消防流体储存装置1，且该喷淋管路2和消防流体储存装置1相连通，该消防流体储存装置1用于储存消防流体，该喷淋管路2与防爆口对应设置。
当某电池单元31热失控并从防爆口排出时，在热流的作用下，喷淋管路2能够形成开口，从而使得喷淋管路2中的消防流体从该开口处排出，降低喷淋管路2中的压力，从而使得消防流体储存装置1中的消防流体进入喷淋管路2，并从开口排出，实现对该电池单元31的喷淋。
其中,本申请中的消防液体包括氟化液，该氟化液从喷淋管路2喷出后，能够与电池单元31的热流发生化学反应，从而起到吸收热量、防止热量扩散的作用。
具体地，如图2～4所示，该消防流体储存装置1包括箱体11，该箱体11具有内腔110和流体出口113，该内腔110用于容纳消防流体，流体出口113与箱体11的内腔110和喷淋管路2连通，从而使得箱体11内腔110中的消防流体能够通过该流体出口113进入喷淋管路2。
同时，该消防流体储存装置1还包括气体发生部件133，气体发生部件133能够产生气体，且在气体发生部件133产生的气体的作用下，能够驱动消防流体朝向流体出口113的方向运动。
本申请中，当电池包A中的电池单元31未发生热失控时，气体发生部件133未产生气体，喷淋管路2未形成开口。当电池包A中的电池单元31发生热失控、从防爆口中喷出热流时，在热流的作用下，该位置的喷淋管路2能够形成开口，喷淋管路2中的消防流体从该开口处排出，且气体发生部件133产生气体，在气体压力的作用下，能够驱动箱体1内腔110中的消防流体进入喷淋管路2，并从喷淋管路2的开口喷出，起到防止热扩散的作用。
同时，该消防流体储存装置1无需设置储气部，从而有助于减小消防流体储存装置1的体积，提高电池包A的能量密度，同时，还有助于增大箱体11内腔110中消防流体的流量，从而提高箱体11的体积利用率。另外，该消防流体储存装置1设置气体发生部件133且该气体发生部件133未产生气体时，箱体11内腔110无高压气体，从而防止因箱 体11内气压过高导致的气体泄漏，且能够避免因箱体11内腔110的压力过高导致的安全性较低。
其中，该气体发生部件133为现有技术中常用的气体发生器，其内部具有产气物质，产气物质混合后，能够释放出气体，且释放出的气体应为不可燃气体，例如氮气等惰性气体，该气体发生部件133的具体结构请参考现有技术。
另外，本申请中的消防流体储存装置1可用于电池包A的喷淋系统，还可用于其他场合。
具体地，该气体发生部件133与箱体11可拆卸连接，当气体发生部件133故障时，便于拆卸维修，如图2所示，该气体发生部件133与箱体11之间通过紧固件131可拆卸连接。
同时，为了防止气体发生部件133处发生泄漏，该气体发生部件133与箱体11的连接处还设置有密封圈14，从而提高该箱体11的密封性能。
在一种可能的设计中，该消防流体储存装置1还包括驱动件12，该驱动件12位于箱体11的内腔110，当气体发生部件133释放气体时，在气体的作用下，该驱动件用12于驱动消防流体朝向流体出口113的方向运动，从而促进消防流体从流体出口113排出，并进入喷淋管路2，从喷淋管路2的开口排出。
本实施例中，通过在消防流体储存装置1内增设驱动件12，当气体发生部件133释放气体时，能够通过该驱动件12驱动消防流体，从而促进消防流体朝向流体出口113的方向流动，并提高消防流体流动的准确性。
在一种可能的设计中，如图5和图6所示，该驱动件12包括安装部121和变形部122，其中，该安装部121与箱体11连接，从而将该驱动件12安装于箱体11，变形部122为柔性件，能够在压力作用下变形。
其中，该变形部122具体可为尼龙材质，能够隔离液体和气体，且能够变形。本实施例中，变形部122的变形包括变形部122形状的改变，当变形部122为弹性结构时，本实施例中的变形可包括弹性变形，即变形部122的壁面发生拉伸或压缩；当变形部122为非弹性结构时，本实 施例中的变形指的是由柔性材料围成的变形部122形状的变化，变形部122的的壁面未发生拉伸或压缩，或者拉伸量(或压缩量)可忽略。
具体地，如图4和图5所示，该变形部122将箱体11的内腔110分隔为第一腔体118和第二腔体119，且第一腔体118与第二腔体119不连通，其中，第一腔体118用于容纳消防流体，第二腔体119用于容纳气体发生部件133产生的气体。同时，该第一腔体118具有第一侧壁118a，第二腔体119具有第二侧壁119a，流体出口113设置于该第一侧壁118a，气体发生部件133设置于该第二侧壁119a。
本实施例中，驱动件12的变形部122作为第一腔体118和第二腔体119的分隔结构，因此，当该变形部122变形时，能够改变第一腔体118与第二腔体119的体积，且第一腔体118的体积减小时，能够驱动其中的消防流体从流体出口113进入喷淋管路2，第一腔体118的体积增大时，能够增大其中的消防流体的流量。且当流体出口113与气体发生部件133分别位于第一侧壁118a和第二侧壁119a时，能够使得消防流体从流体出口113快速排出，提高喷淋系统的灵敏性。
在一种可能的设计中，如图2所示，该第一侧壁118a与第二侧壁119a相对设置，即流体出口113与气体发生部件133相对设置，从而能够进一步促进消防流体从流体出口113快速排出。
具体地，如图5所示，该变形部122的壁面围成第三腔体123，该第三腔体123用于容纳消防流体或气体。其中，变形部122在工作过程中，当其两侧的压力变化时，该变形部122的状态也随之不断变化，在多个变形状态中，该变形部122至少具有如图3所示的第一变形状态和如图4所示的第二变形状态。
如图4所示，该变形部122在第二变形状态时，沿长度方向X，该变形部122与气体发生部件133之间具有第二预设距离，该第二预设距离使得变形部122与气体发生部件133之间不接触，从而使得该气体发生部件133能够释放气体，且该第二预设距离较小，即变形部122靠近气体发生部件133，从而使得第二腔体119的体积和气压较小，第一腔体118的体积较大，使得该消防流体储存装置1能够处于充液状态，即 消防流体能够经流体进口进入第一腔体118，且随着液压力的增大，能够促进变形部122朝向第二侧壁119a的方向变形，此时，该变形部122的第三腔体123朝向第一腔体118的方向，并能够用于储存消防流体，从而使得消防流体能够接近充满整个箱体11的内腔110，增大箱体11储存的消防流体流量。
如图3所示，当气体发生部件133受到触发释放出气体时，第二腔体119内的气体压力逐渐增大，从而驱动变形部122朝向第一侧壁118a的方向变形，驱动第一腔体118内的消防流体从流体出口113排出，且随着第二腔体119内压力逐渐增大，沿长度方向X，该变形部122与第一侧壁118a之间的第一预设距离逐渐减小，且随着消防流体从流体出口113排出以及气体发生部件133释放气体，该变形部122的至少部分能够与第一侧壁118a抵接，此时，变形部122的第三腔体123朝向第二腔体119的方向，并能够用于储存气体，从而促进第一腔体118内的消防流体完全排出，提高消防流体的利用率。
因此，本实施例中，该驱动件12在满足足够流量的消防流体排出至喷淋管路2的同时，能够减小消防流体储存装置的体积，提高其利用率，并提高电池包A的能量密度。
另一方面，如图2～4所示，沿高度方向Z，该安装部121具有相对设置的上端部121a和下端部121b，其中，该安装部121中，上端部121a与下端部121b用于与箱体11连接。在一种具体实施例中，该上端部121a靠近第一侧壁118a，下端部121b靠近第二侧壁112c，因此，该安装部121沿高度方向Z倾斜设置；在另一种具体实施例中，上端部121a靠近第二侧壁112c，下端部121b靠近第一侧壁118a，此时，该安装部121沿高度方向Z倾斜设置。
本实施例中，与安装部121沿竖直平面布置或沿水平面布置相比，该安装部121倾斜布置时，变形部122变形后能够与第一侧壁118a或第二侧壁112c接近贴合，从而能够增大该箱体11内储存的消防流体的流量，并能够促进箱体11内腔110的消防流体完全排出，进一步提高消防流体储存装置的利用率和电池包A的能量密度。
具体地，如图2所示，该箱体11为矩形结构，包括顶壁114、底壁115和四个侧壁，且顶壁114与第一腔体118的第一侧壁118a相连的位置形成第一弯折部116，底壁115与第二腔体119的第二侧壁119a相连的位置形成第二弯折部117，该第一弯折部116与第二弯折部117为该箱体11的对角线位置。因此，沿高度方向Z，该安装部121的一端与第一弯折部116固定连接，另一端与第二弯折部117固定连接，即该安装部121沿箱体11的对角线布置，从而进一步增大该箱体11内储存的消防流体的流量，并能够促进箱体11内腔110的消防流体完全排出，提高消防流体储存装置的利用率和电池包A的能量密度。
需要说明的是，如图2～4所示，该第二侧壁119a设置有气体发生部件133，因此，该气体发生部件133占据第二腔体119的一部分空间，因此，该第二弯折部117与第二侧壁119a具有一段距离。
以上各实施例中，该箱体11包括分体设置的第一箱体111和第二箱体112，该第一箱体111与第二箱体112均为近似三棱柱结构，二者拼接形成矩形的箱体11，如图7和图8所示，安装部121位于该第一箱体111和第二箱体112之间，并通过第一箱体111和第二箱体112压紧，从而实现驱动件12在箱体11内的安装。
其中，上述第一弯折部116为第一箱体111的一部分，且该第一弯折部116为第一箱体111的一个端部，因此，该第一弯折部116与第二箱体112对应的端部对接，第二弯折部117为第二箱体112的一部分，且该第二弯折部117为第二箱体112的一个端部，因此，该第二弯折部117与第一箱体111对应的端部对接。
同时，如图2所示，该第一箱体111与第二箱体112中，二者相对应的其他端部也对接，从而实现第一箱体111与第二箱体112的固定连接，且二者连接形成完整的箱体11。上述驱动件12的安装部121位于第一箱体111与第二箱体112的端部之间，从而通过第一箱体111与第二箱体112压紧。
本实施例中，分体设置的箱体11能够便于驱动件12的安装，且该第一箱体111与安装部121之间、第二箱体112与安装部121之间还设 置有密封胶15，从而通过密封胶15提高安装部121与箱体11的安装可靠性和密封性，且变形部122变形过程中，安装部121保持不动。
其中，该驱动件12中，变形部122为柔性可变形结构，而安装部121为刚性结构，以便提高安装部121与箱体11的安装可靠性。
需要说明的是，上述第一腔体118并非第一箱体111的内腔，第二腔体119也并非第二箱体112的内腔，第一箱体111的内腔和第二箱体112的内腔为矩形箱体11内腔110的一半，而第一腔体118与第二腔体119的形状和大小随变形部122的变形不断改变，且二者近似围成箱体11的内腔110。
另外，该第一箱体111中，靠近流体出口113的一侧设置有凹陷部111a，从而能够促进消防流体从流体出口113排出；该第二箱体112的外侧壁设置有支架112a，该箱体11通过该支架112a固定于电池包A壳体4的容纳腔41内，且该支架112a设于第二侧壁119a。
以上各实施例中，该消防流体储存装置1包括气体发生组件13，其中，该气体发生组件13包括上述气体发生部件133以及点火线132，且该点火线132与气体发生部件133连接，当满足触发条件时，该点火线132用于向气体发生部件133通电，以驱动气体发生部件133释放气体。具体地，该触发条件为电池包A内任意电池单元31发生热失控，电池包A的监测装置监测到电池单元31发生热失控时，控制装置能够发送控制信号至点火线132，点火线132向气体发生部件133通电，实现消防流体的排出。
或者，上述气体发生组件13中，该气体发生部件133内部设置有包括温控保险丝的控制电路，当该电池包A内的任意电池单元31发生热失控时，该电池包A内的问题升高，因此，当该温控保险丝达到预设温度时，该温控保险丝熔断，控制电路控制气体发生部件133释放气体。其中，该预设温度设置为一个电池单元31发生热失控时电池包A达到的最低温度，以便及时排出消防流体。
本申请实施例还提供一种电动车，包括如上述的电池包A。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡 在本申请的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本申请保护的范围之内。
