本申请实施例涉及电池领域，并且更具体地，涉及一种电池、用电装置、制备电池的方法和装置。
背景技术
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
本申请提供一种电池、用电装置、制备电池的方法和装置，能够增强电池的安全性。
第一方面，提供一种电池，包括：电池单体，包括第一壁，该第一壁上设置有泄压机构，该泄压机构用于在电池单体的内部压力或温度达到阈值时致动以泄放内部压力；消防管道，用于容纳消防介质，该消防管道用于在泄压机构致动时排出消防介质；固定件，设置在第一壁和消防管道之间，该固定件用于固定消防管道；其中，消防管道包括第一限位部，固定件包括第二限位部，第一限位部与第二限位部相互配合，以在第一方向和第二方向上对消防管道进行限位，第一方向垂直于第一壁，第二方向平行于第一壁且垂直于消防管道的延伸方向。
通过本申请实施例的技术方案，在电池中设置消防管道，可以在电池单体的泄压机构致动时排出消防介质，对电池单体的排放物乃至电池单体的内部进行降温，提升电池的安全性能。在此基础上，消防管道上设置有第一限位部，且电池中还设置有固定件，该固定件上设置有第二限位部，该第一限位部和第二限位部相互配合，对消防管道在多个方向上进行限位，可使得消防管道较为稳定的设置于电池中，并起到较为可靠的消防以及温度调节效果，以增强电池的安全性能。
在一些可能的实施方式中，第一限位部为单卡爪结构，单卡爪结构包括连接部和第一卡爪部，连接部由消防管道的管壁沿第二方向延伸形成，第一卡爪部连接于连接部，并朝向电池单体延伸，第一卡爪部卡接于第二限位部。
通过该实施方式的技术方案，将消防管道上的第一限位部设计为单卡爪结构， 并与固定件上的第二限位部实现卡接，在保证第一限位部与第二限位部之间的连接稳定性的同时，能够较为方便的实现单卡爪结构在消防管道上的设置，相对提高消防管道的生产效率。
在一些可能的实施方式中，第二限位部为卡槽结构，卡槽结构包括沿第二方向排列的第一卡槽壁和第二卡槽壁，第一卡槽壁与第二卡槽壁用于夹持第一卡爪部，以在第一方向和第二方向上对消防管道进行限位。
通过该实施方式的技术方案，将固定件上的第二限位部设计为配合于第一卡爪部的卡槽结构，该卡槽结构中的第一卡槽壁和第二卡槽壁对第一卡爪部进行夹持，可提高第一限位部和第二限位部之间的卡接强度，从而提升在第一方向和第二方向上对消防管道的限位和固定效果，提高消防管道在电池中的安装稳定性。
在一些可能的实施方式中，第一卡槽壁和/或第二卡槽壁远离电池单体的一端设置有第一凸起，第一卡爪部靠近电池单体的一端设置有第二凸起，第一凸起与第二凸起相互配合，以在第一方向上对消防管道进行限位。
通过该实施方式的技术方案，当第一卡槽壁和/或第二卡槽壁与第一卡爪部相互卡接后，第一卡爪部上的第二凸起相对于第一卡槽壁和/或第二卡槽壁上的第一凸起朝向电池单体设置，该第一凸起能够防止第二凸起及其所在的第一卡爪部远离电池单体，从而进一步提高第二限位部与第一限位部在第一方向上的卡接强度，以提高消防管道在第一方向上的限位和固定效果。
在一些可能的实施方式中，第一凸起远离电池单体的一端设置有第一倾斜面，第二凸起靠近电池单体的一端设置有第二倾斜面，第一倾斜面与第二倾斜面相互对应，且分别倾斜于垂直于第一壁的所在平面。
通过该实施方式的技术方案，在第一卡爪部设置有第一凸起，且第一卡槽壁和/或第二卡槽壁设置有与第一凸起相互配合的第二凸起的基础上，该第一凸起和第二凸起上可分别设置有相互配合的倾斜面，在保证第一卡爪部与第一卡槽壁和第二卡槽壁能够具有较佳的卡接效果的同时，还能进一步提高第一卡爪部在第一卡槽壁和第二卡槽壁之间的安装效率。因此，通过该实施方式的技术方案，在保证消防管道在电池中的安装稳定性的同时，可提升消防管道在电池中的安装效率。
在一些可能的实施方式中，卡槽结构沿第三方向延伸，第一卡爪部能够沿第三方向在卡槽结构中滑动，其中，第三方向平行于第一壁且平行于消防管道的延伸方向。
通过该实施方式的技术方案，卡槽结构的第二限位部沿第三方向延伸，因而卡槽结构在该第三方向上具有一定的长度。消防管道中的第一卡爪部能够沿第三方向在该卡槽结构中滑动。在电池单体的运行过程中，由于其内部的化学反应，电池单体会产生膨胀。当电池单体在第三方向上产生膨胀时，会引起位于其第一壁的固定件的位置变化，乃至引起该固定件上的第二限位部的位置变化。由于消防管道中的第一卡爪部能够沿第三方向在卡槽结构的第二限位部中滑动，即使电池单体的膨胀会引起第二限位部的位置变化，但对消防管道的影响较小或者没有影响，因此，即使电池单体发生膨胀，消防管道在电池中安装稳定性仍然较高。
在一些可能的实施方式中，第一限位部为双卡爪结构，双卡爪结构包括：连接 部、沿第二方向排列的第一卡爪部和第二卡爪部，连接部由消防管道的管壁沿第二方向延伸形成，第一卡爪部和第二卡爪部连接于连接部，并朝向电池单体延伸；第一卡爪部和第二卡爪部用于夹持第二限位部，以在第一方向和第二方向上对消防管道进行限位。
通过该实施方式的技术方案，在消防管道上设置双卡爪结构的第一限位部，该双卡爪结构用于夹持固定件上的第二限位部，以实现消防管道在电池中的安装。具体的，当双卡爪结构夹持于第二限位部后，双卡爪结构可在第二方向中的两个相反的子方向上均对第二限位部实现良好的限位和固定效果，使得消防管道在第二方向上具有较高的稳定性。再者，双卡爪结构夹持第二限位部时，双卡爪结构与第二限位部之间可具有第一方向上的相互作用力，以保证消防管道在第一方向上也具有一定的稳定性。
在一些可能的实施方式中，第二限位部为卡扣结构，卡扣结构包括沿第一方向排列的第一卡扣部和第二卡扣部，第一卡扣部由固定件沿远离电池单体的方向延伸形成，第二卡扣部设置于第一卡扣部远离电池单体的一端，在第二方向上，第二卡扣部的尺寸不小于第一卡扣部的尺寸，第一卡爪部和/或第二卡爪部卡接于第二卡扣部。
通过该实施方式的技术方案，将第二限位部设计为包括第一卡扣部和第二卡扣部的卡扣结构，其中，第二卡扣部朝向消防管道设置，且该第二卡扣部在第二方向上的尺寸不小于第一卡扣部在第二方向上的尺寸，因此，利用该尺寸较大的第二卡扣部，可以易于实现该第二卡扣部在消防管道的双卡爪结构中的卡接，且提高该第二卡扣部在双卡爪结构中的卡接强度。
在一些可能的实施方式中，第一卡爪部和/或第二卡爪部靠近电池单体的一端设置有第三凸起；第二卡扣部包括沿第二方向相对于第一卡扣部突出的第四凸起，第四凸起与第三凸起相互配合，以在第一方向上对消防管道进行限位。
通过该实施方式的技术方案，当第一卡爪部和/或第二卡爪部与第二卡扣部相互卡接后，第二卡扣部上的第四凸起相对于第一卡爪部和/或第二卡爪部上的第三凸起远离电池单体设置，该第四凸起能够防止第三凸起及其所在的第一卡爪部和/或第二卡爪部远离电池单体，从而进一步提高第二限位部与第一限位部在第一方向上的卡接强度，以提高消防管道在第一方向上的限位和固定效果。
在一些可能的实施方式中，第三凸起靠近电池单体的一端设置有第三倾斜面，第四凸起远离电池单体的一端设置有第四倾斜面，第三倾斜面与第四倾斜面相互对应，且分别倾斜于垂直于第一壁的所在平面。
通过该实施方式的技术方案，在第一卡爪部和/或第二卡爪部设置有第三凸起，且第二卡扣部设置有与第三凸起相互配合的第四凸起的基础上，该第三凸起和第四凸起上可分别设置有相互配合的倾斜面，在保证第二卡扣部与第一卡爪部和第二卡爪部能够具有较佳的卡接效果的同时，还能进一步提高第二卡扣部在第一卡爪部和第二卡爪部之间的安装效率，从而在保证消防管道在电池中的安装稳定性的同时，提升消防管道在电池中的安装效率。
在一些可能的实施方式中，双卡爪结构沿第三方向延伸，第二限位部能够沿第三方向在双卡爪结构中滑动，其中，第三方向平行于第一壁且平行于消防管道的延伸 方向。
通过该实施方式的技术方案，双卡爪结构的第一限位部沿第三方向延伸，因而双卡爪结构在该第三方向上具有一定的长度。固定件中的第二限位部能够沿第三方向在该双卡爪结构中滑动。在电池单体的运行过程中，由于其内部的化学反应，电池单体会产生膨胀。当电池单体在第三方向上产生膨胀时，会引起位于其第一壁的固定件的位置变化，乃至引起该固定件上的第二限位部的位置变化。由于第二限位部能够沿第三方向在双卡爪结构中滑动，即使电池单体的膨胀会引起第二限位部的位置变化，但对消防管道的影响较小或者没有影响，因此，即使电池单体发生膨胀，消防管道在电池中安装稳定性仍然较高。
在一些可能的实施方式中，第一限位部沿第三方向延伸，在第三方向上，第一限位部的延伸长度与消防管道的延伸长度相同，其中，第三方向平行于第一壁且平行于消防管道的延伸方向。
通过该实施方式的技术方案，可以便于消防管道通过其第一限位部安装于多个不同位置的固定件。作为一种示例，在不同类型的电池单体中，电池单体在第三方向上的尺寸可能发生变化，因此，不同类型的电池单体上的固定件的位置也可能会发生相应变化。作为另一示例，在多个电池单体中，可以仅在部分电池单体的第一壁上设置固定件，在不同的应用需求下，固定件在多个电池单体上的位置也可能会发生调整和变化。在上述两种示例的情况下，通过本申请实施例的技术方案，仍然可以利用该消防管道上的第一限位部与固定件配合安装。换言之，消防管道的固定安装不会因为多个电池单体上固定件的位置变化而产生影响。通过该实施方式的技术方案，不仅可以提高消防管道在电池中的安装效率，还可以使得消防管道能够适用于更多的应用场景，有利于消防管道在多种不同类型的电池中的推广和使用。
在一些可能的实施方式中，消防管道包括至少一对第一限位部，在第二方向上，每对第一限位部分别位于消防管道的两侧；固定件包括至少一对第二限位部，每对第二限位部与每对第一限位部对应设置。
通过该实施方式的技术方案，消防管道在第二方向上的两侧设置有至少一对第一限位部，该至少一对第一限位部通过与其对应的至少一对第二限位部相互配合，实现对消防管道在第二方向上较为可靠和稳定的限位和固定，从而提升消防管道在电池中的安装稳定性。
在一些可能的实施方式中，消防管道包括沿第一方向相对设置的第一管壁和第二管壁，第一管壁相对于第二管壁更远离电池单体，其中，第一管壁的厚度大于第二管壁的厚度，和/或，第一管壁设置有加强件。
通过该实施方式的技术方案，在消防管道中，远离电池单体的第一管壁的厚度大于靠近电池单体的第二管壁的厚度，和/或，第一管壁设置有加强件，因此，远离电池单体的第一管壁可具有较高的强度，能够较大程度的承受外力对消防管道造成的冲击，提升消防管道在电池中的使用可靠性。
在一些可能的实施方式中，在第二方向上，第一管壁的尺寸大于第二管壁的尺寸。
通过该实施方式的技术方案，在消防管道中，通过设计第一管壁与第二管壁在第二方向上的尺寸，也可以使得第一管壁的强度强于第二管壁，即第一管壁可具有较高的强度，能够较大程度的承受外力对消防管道造成的冲击，提升消防管道在电池中的使用可靠性。另外，当电池单体内部的排放物经过泄压机构冲击第一管壁时，可能会使得第二管壁整体贴附于第一管壁，当第一管壁与第二管壁的尺寸相同时，该相互贴附的第二管壁与第一管壁会阻塞流道，从而阻碍消防管道中的消防介质流入对应的泄压机构以及电池单体内部，影响消防管道的消防效果。而通过本实施方式的技术方案，第一管壁在第二方向上的尺寸大于第二管壁在第二方向上的尺寸，即使第二管壁贴附于第一管壁，也不会完全阻塞流道，可以使得消防介质流入对应的泄压机构以及电池单体内部，以起到良好的消防作用。
第二方面，提供一种用电装置，包括：第一方面或第一方面中任一可能的实施方式中的电池，该电池用于向用电装置提供电能。
第三方面，提供一种制备电池的方法，包括：提供电池单体，电池单体包括第一壁，第一壁上设置有泄压机构，泄压机构用于电池单体的内部压力或温度达到阈值时致动以泄放内部压力；提供消防管道，消防管道用于容纳消防介质，并在泄压机构致动时排出消防介质；提供固定件，固定件设置在第一壁和消防管道之间；将消防管道固定安装于固定件；其中，消防管道包括第一限位部，固定件包括第二限位部，第一限位部与第二限位部相互配合，以在第一方向和第二方向上对消防管道进行限位，第一方向垂直于第一壁，第二方向平行于第一壁且垂直于消防管道的延伸方向。
第四方面，提供一种制备电池的装置，包括：提供模块，用于：提供电池单体，电池单体包括第一壁，第一壁上设置有泄压机构，泄压机构用于电池单体的内部压力或温度达到阈值时致动以泄放内部压力；提供消防管道，消防管道用于容纳消防介质，并在泄压机构致动时排出消防介质；提供固定件，固定件设置在第一壁和消防管道之间；安装模块，用于将消防管道固定安装于固定件；其中，消防管道包括第一限位部，固定件包括第二限位部，第一限位部与第二限位部相互配合，以在第一方向和第二方向上对消防管道进行限位，第一方向垂直于第一壁，第二方向平行于第一壁且垂直于消防管道的延伸方向。
通过本申请实施例的技术方案，在电池中设置消防管道，可以在电池单体的泄压机构致动时排出消防介质，对电池单体的排放物乃至电池单体的内部进行降温，提升电池的安全性能。在此基础上，消防管道上设置有第一限位部，且电池中还设置有固定件，该固定件上设置有第二限位部，该第一限位部和第二限位部相互配合，对消防管道在多个方向上进行限位，可使得消防管道较为稳定的设置于电池中，并起到较为可靠的消防以及温度调节效果，以增强电池的安全性能。

电池单体包括电极组件和电解液，电极组件由正极片、负极片和隔离膜组成。电池单体主要依靠金属离子在正极片和负极片之间移动来工作。正极片包括正极集流体和正极活性物质层，正极活性物质层涂覆于正极集流体的表面，未涂敷正极活性物质层的集流体凸出于已涂覆正极活性物质层的集流体，未涂敷正极活性物质层的集流体作为正极极耳。以锂离子电池为例，正极集流体的材料可以为铝，正极活性物质可以为钴酸锂、磷酸铁锂、三元锂或锰酸锂等。负极片包括负极集流体和负极活性物质层，负极活性物质层涂覆于负极集流体的表面，未涂敷负极活性物质层的集流体凸出于已涂覆负极活性物质层的集流体，未涂敷负极活性物质层的集流体作为负极极耳。负极集流体的材料可以为铜，负极活性物质可以为碳或硅等。为了保证通过大电流而不发生熔断，正极极耳的数量为多个且层叠在一起，负极极耳的数量为多个且层叠在一起。隔膜的材质可以为聚丙烯(Polypropylene，PP)或聚乙烯(Polyethylene，PE)等。此外，电极组件可以是卷绕式结构，也可以是叠片式结构，本申请实施例并不限于此。
电池技术的发展要同时考虑多方面的设计因素，例如，能量密度、循环寿命、 放电容量、充放电倍率等性能参数，另外，还需要考虑电池的安全性。
对于电池来说，主要的安全危险来自于充电和放电过程，为了提高电池的安全性能，对电池单体一般会设置泄压机构。泄压机构是指电池单体的内部压力或温度达到预定阈值时致动以泄放内部压力或温度的元件或部件。该预定阈值可以根据设计需求不同而进行调整。所述预定阈值可取决于电池单体中的正极极片、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，当电池单体的内部压力或温度达到预定阈值时，泄压机构致动，从而形成可供内部压力或温度泄放的通道。
本申请中所提到的“致动”是指泄压机构产生动作，从而使得电池单体的内部压力及温度得以被泄放。泄压机构产生的动作可以包括但不限于：泄压机构中的至少一部分破裂、被撕裂或者熔化，等等。泄压机构在致动后，电池单体内部的高温高压物质作为排放物会从泄压机构向外排出。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的排放物包括但不限于：电解液、被溶解或分裂的正负极极片、隔离膜的碎片、反应产生的高温高压气体、火焰，等等。
电池单体上的泄压机构对电池的安全性有着重要影响。例如，当电池单体发生短路、过充等现象时，可能会导致电池单体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致动可以将内部压力及温度向外释放，以防止电池单体爆炸、起火。
除了在电池单体上设置泄压机构以保障电池的安全性以外，用于容纳电池单体的箱体中还可设置有消防管道，该消防管道中可容纳有消防介质，该消防介质可为消防液体、消防气体或者还可以为消防固体。可选地，在一些实施方式中，消防管道可与电池单体中的泄压机构对应设置。当该泄压机构致动时，从电池单体内泄放的排放物会破坏消防管道的壁，使得消防介质从消防管道中流出，消防介质可以对电池单体的高温排放物进行降温，降低排放物的危险性，从而提升电池单体以及电池整体的安全性能。
在一些相关技术中，会利用支架将消防管道安装于电池单体中泄压机构所在的壁。例如，在电池单体中泄压机构所在的壁上设置支架，消防管道设置于支架上，且与泄压机构对应设置。支架上仅具有简单的限位结构，例如凹槽等，对消防管道起到较为有限的固定作用。因此，在该技术方案中，消防管道在电池中的安装稳定性不佳。当电池所在的用电装置(例如：电动车辆)等处于运动状态时，会对电池中的消防管道产生一定的影响，在消防管道的安装稳定性不佳的情况下，消防管道会产生震动乃至从电池单体上脱落，进而影响消防管道的正常使用并带来电池的安全隐患。
鉴于此，本申请提供一种电池，该电池中的消防管道上设置有第一限位部，且电池中还包括固定件，该固定件中的第二限位部和消防管道上的第一限位部能够相互配合，以实现在多个方式向上对消防管道进行限位和固定，提高消防管道在电池中的安装稳定性，从而提升电池的安全性能。
本申请实施例描述的技术方案适用于各种使用电池的装置，例如，手机、便携 式设备、笔记本电脑、电瓶车、电动玩具、电动工具、电动车辆、船舶和航天器等，例如，航天器包括飞机、火箭、航天飞机和宇宙飞船等。
应理解，本申请实施例描述的技术方案不仅仅局限适用于上述所描述的装置，还可以适用于所有使用电池的装置，但为描述简洁，下述实施例均以电动车辆为例进行说明。
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11，控制器12以及电池10，控制器12用来控制电池10为马达11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的电路系统，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。
为了满足不同的使用电力需求，电池可以包括多个电池单体，其中，多个电池单体之间可以串联或并联或混联，混联是指串联和并联的混合。电池也可以称为电池包。可选地，多个电池单体可以先串联或并联或混联组成电池模块，多个电池模块再串联或并联或混联组成电池。也就是说，多个电池单体可以直接组成电池，也可以先组成电池模块，电池模块再组成电池。
例如，如图2所示，为本申请一个实施例的一种电池10的结构示意图，电池10可以包括多个电池单体20。电池10还可以包括箱体100(或称罩体)，箱体100内部为中空结构，多个电池单体20容纳于箱体100内。如图2所示，箱体100可以包括两部分，这里分别称为第一部分111和第二部分112，第一部分111和第二部分112扣合在一起。第一部分111和第二部分112的形状可以根据多个电池单体20组合的形状而定，第一部分111和第二部分112可以均具有一个开口。例如，第一部分111和第二部分112均可以为中空长方体且各自只有一个面为开口面，第一部分111的开口和第二部分112的开口相对设置，并且第一部分111和第二部分112相互扣合形成具有封闭腔室的箱体100。多个电池单体20相互并联或串联或混联组合后置于第一部分111和第二部分112扣合后形成的箱体100内。
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，汇流部件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，汇流部件可通过连接电池单体20的电极端子实现电池单体20之间的电连接。进一步地，汇流部件可通过焊接固定于电池单体20的电极端子。多个电池单体20的电能可进一步通过导电机构穿过箱体而引出。可选地，导电机构也可属于汇流部件。
根据不同的电力需求，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，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。
图3示出了本申请一个实施例的电池单体20的结构示意图。
如图3所示，电池单体20包括一个或多个电极组件22、壳体211和盖板212。壳体211的壁以及盖板212均称为电池单体20的壁。壳体211根据一个或多个电极组件22组合后的形状而定，例如，壳体211可以为中空的长方体或正方体或圆柱体，且壳体211的其中一个面具有开口以便一个或多个电极组件22可以放置于壳体211内。例如，当壳体211为中空的长方体或正方体时，壳体211的其中一个平面为开口面，即该平面不具有壁体而使得壳体211内外相通。当壳体211可以为中空的圆柱体时，壳体211的端面为开口面，即该端面不具有壁体而使得壳体211内外相通。盖板212覆盖开口并且与壳体211连接，以形成放置电极组件22的封闭的腔体。壳体211内填充有电解质，例如电解液。
该电池单体20还可以包括两个电极端子214，两个电极端子214可以设置在盖板212上。盖板212通常是平板形状，两个电极端子214固定在盖板212的平板面上，两个电极端子214分别为正电极端子214a和负电极端子214b。每个电极端子214各对应设置一个连接构件23，或者也可以称为集流构件23，其位于盖板212与电极组件22之间，用于将电极组件22和电极端子214实现电连接。
如图3所示，每个电极组件22具有第一极耳221a和第二极耳222a。第一极耳221a和第二极耳222a的极性相反。例如，当第一极耳221a为正极极耳时，第二极耳222a为负极极耳。一个或多个电极组件22的第一极耳221a通过一个连接构件23与一个电极端子连接，一个或多个电极组件22的第二极耳222a通过另一个连接构件23与另一个电极端子连接。例如，正电极端子214a通过一个连接构件23与正极极耳连接，负电极端子214b通过另一个连接构件23与负极极耳连接。
在该电池单体20中，根据实际使用需求，电极组件22可设置为单个，或多个，如图3所示，电池单体20内设置有4个独立的电极组件22。
作为示例，电池单体20的一个壁上还可设置泄压机构213。泄压机构213用于电池单体20的内部压力或温度达到阈值时致动以泄放内部压力或温度。
可选地，在本申请另一个实施例中，泄压机构213和电极端子214设置于电池单体20的同一壁。例如，如图3所示，电极端子214和泄压机构213均可设置于电池单体20的顶壁，即盖板212。
将泄压机构213和电极端子214设置于电池单体20的同一壁上，例如设置于电池单体20的盖板212，可以方便泄压机构213和电极端子214的加工和安装，有利于提高电池10的生产效率。
可选地，在本申请一个实施例中，泄压机构213和电极端子214设置于电池单体20的不同壁。例如，电池单体20的电极端子214可设置于电池单体20的顶壁，即盖板212。泄压机构213设置于电池单体20中不同于顶壁的另一个壁，例如，泄压机构213设置于与顶壁相对的底壁。
上述泄压机构213可以为其所在壁的一部分，也可以与其所在壁为分体式结构，通过例如焊接的方式固定在其所在壁上。例如，在图3所示实施例中，当泄压机构213 为底壁的一部分时，泄压机构213可以通过在底壁上设置刻痕的方式形成，与该刻痕的对应的底壁厚度小于泄压机构213除刻痕处其他区域的厚度。刻痕处是泄压机构213最薄弱的位置。当电池单体20产生的气体太多使得壳体211内部压力升高并达到阈值或电池单体20内部反应产生热量造成电池单体20内部温度升高并达到阈值时，泄压机构213可以在刻痕处发生破裂而导致壳体211内外相通，气体压力及温度通过泄压机构213的裂开向外释放，进而避免电池单体20发生爆炸。
另外，泄压机构213可以为各种可能的泄压机构，本申请实施例对此并不限定。例如，泄压机构213可以为温敏泄压机构，温敏泄压机构被配置为在设有泄压机构213的电池单体20的内部温度达到阈值时能够熔化；和/或，泄压机构213可以为压敏泄压机构，压敏泄压机构被配置为在设有泄压机构213的电池单体20的内部气压达到阈值时能够破裂。
图4示出了本申请一实施例提供的电池10的截面爆炸示意图。
如图4所示，电池10包括：电池单体20，包括第一壁201，该第一壁201上设置有泄压机构213，该泄压机构213用于在电池单体20的内部压力或温度达到阈值时致动以泄放内部压力；消防管道30，用于容纳消防介质，该消防管道30用于在泄压机构213致动时排出消防介质；固定件40，设置在第一壁201和消防管道30之间，该固定件40用于固定消防管道30；其中，该消防管道30包括第一限位部310，固定件40包括第二限位部410，该第一限位部310与第二限位部410相互配合，以在第一方向x和第二方向y上对消防管道30进行限位，第一方向x垂直于第一壁201，该第二方向y平行于第一壁201且垂直于消防管道30的延伸方向。
具体地，在本申请实施例中，电池单体20中的第一壁201可以为图3所示实施例中盖板212，或者，也可以为壳体211中的任意壁。可选地，该第一壁201不为电池单体20中面积最大的壁，该电池单体20中面积最大的壁可用于与其它电池单体20或者箱体100相互附接，提高电池单体20在箱体中的安装稳定性。
在该第一壁201中设置有泄压机构213，参照上文所述，该泄压机构213可以为第一壁201的一部分，也可以与第一壁201为分体式结构。该泄压机构213可以为温敏泄压机构、压敏泄压机构或者其它类型的泄压机构。关于泄压机构213的相关技术方案可以参见上文实施例的相关描述，此处不再赘述。
作为示意，在本申请实施例中，泄压机构213和电极端子214均可设置于该第一壁201，可以方便泄压机构213和电极端子214的加工和安装，有利于提高电池10的生产效率。当然，在其它替代实施例中，泄压机构213和电极端子214也可处于电池单体20中的不同壁。
请继续参见图4，在本申请实施例中，消防管道30与第一壁201对应设置。可选地，消防管道30与第一壁201上的泄压机构213对应设置。该消防管道30中容纳有消防介质，当泄压机构213致动并泄放来自电池单体20内部的高温排放物时，消防管道30可排出消防介质以对该高温排放物进行降温，防止该高温排放物对电池10产生影响并带来安全隐患。进一步地，在消防管道30与泄压机构213对应设置的情况下，通过消防管道30排出的消防介质可通过致动后的泄压机构213流入电池单体20的内部， 对电池单体20的内部进行降温，防止该电池单体20的高温传递至其它电池单体20从而对其它电池单体20产生影响。
可选地，消防管道30中的消防介质可为冷却介质，其具有较低的温度，除了可以在泄压机构213致动时，起到更好的降温效果以外，在泄压机构213未致动时，也可以对电池单体20起到冷却的效果，防止电池单体20的温度过高更容易引发安全问题。可选地，该消防介质可以是消防气体、消防液体或者还可以是消防固体。在一些实施方式中，该消防介质可以是循环流动的，以达到更好的降温效果。作为示例而非限定，在本申请实施例中，消防介质可以为水、水和乙二醇的混合液或者空气等等。
作为示例而非限定，如图4所示，消防管道30的主体部可为截面为环形的管道。除了主体部以外，消防管道30还可进一步包括第一限位部310，其连接于消防管道30的主体部。可选地，该第一限位部310可与消防管道30的主体部为一体成型结构，或者，该第一限位部310也可与消防管道30的主体部为分体式结构，例如，该第一限位部310可通过焊接等机械连接方式固定于消防管道30的主体部。该第一限位部310用于配合消防管道30与电池单体20的第一壁201之间的固定件40，实现消防管道30在电池单体20的第一壁201上的固定。
具体地，继续参见图4，固定件40包括第二限位部410，上述消防管道30中的第一限位部310与该第二限位部410相互配合，以在第一方向x和第二方向y上对消防管道30进行限位，其中，第一方向x垂直于第一壁201，该第二方向y平行于第一壁201且垂直于消防管道30的延伸方向。
可选地，在一些实施方式中，固定件40可仅包括第二限位部410，该第二限位部410可通过焊接等机械连接方式固定设置于电池单体20的第一壁201。
或者，在另一些实施方式中，固定件40除了包括第二限位部410以外，还可以包括其它结构件，以便于固定件40及其第二限位部410在第一壁201上的安装。作为示例，如图4所示，除了第二限位部410以外，固定件40可包括安装部，第二限位部410设置于安装部上，通过将安装部安装于第一壁201，可实现第二限位部410在第一壁201上的稳定设置。
对于第一限位部310和第二限位部410的相互配合连接，作为示例而非限定，在图4所示的实施方式中，在第二方向y上，第一限位部310分别设置于消防管道30的两侧；在第一方向x上，第二限位部410朝向消防管道30凸起，且与第一限位部310对应设置。当第一限位部310和第二限位部410相互配合时，第一限位部310和第二限位部410可在第一方向x和第二方向y上相互抵接，以实现在第一方向x和第二方向y上对消防管道30的限位。
可选地，第一限位部310和第二限位部410除了可设置为图4所示的相互配合的机械结构以外，还可以设置为卡扣卡槽、轴孔插接、凹凸配合等相关方式的机械结构，以实现在第一方向x和第二方向y上对消防管道30的限位。本申请实施例对第一限位部310和第二限位部410的具体结构以及相互配合的具体方式不做限定，旨在能够实现在第一方向x和第二方向y上对消防管道30进行限位即可。
通过本申请实施例的技术方案，在电池10中设置消防管道30，可以在电池单 体20的泄压机构213致动时排出消防介质，对电池单体20的排放物乃至电池单体20的内部进行降温，提升电池10的安全性能。在此基础上，消防管道30上设置有第一限位部310，且电池10中还设置有固定件40，该固定件40上设置有第二限位部410，该第一限位部310和第二限位部410相互配合，对消防管道30在多个方向上进行限位，使得消防管道30可较为稳定的设置于电池10中，并起到较为可靠的消防以及温度调节效果，以增强电池10的安全性能。
图5示出了本申请一实施例提供的电池10的另一截面爆炸示意图，图6示出了图5中A部分的局部放大示意图。
结合图5和图6所示，在本申请实施例中，消防管道30上的第一限位部310为单卡爪结构，该单卡爪结构包括连接部311和第一卡爪部312，该连接部311由消防管道30的管壁沿第二方向y延伸形成，第一卡爪部312连接于该连接部311，并朝向电池单体20延伸，且该第一卡爪部312卡接于第二限位部410。
通过本申请实施例的技术方案，将消防管道30上的第一限位部310设计为单卡爪结构，并与固定件40上的第二限位部410实现卡接，在保证第一限位部310与第二限位部410之间的连接稳定性的同时，能够较为方便的实现单卡爪结构在消防管道30上的设置，相对提高消防管道30的生产效率。
可选地，如图6所示，消防管道30在第二方向y上的两侧分别设置有第一限位部310，即消防管道30在第二方向y上的两侧分别设置有单卡爪结构，利用消防管道30两侧的单卡爪结构卡接于第二限位部410，能够进一步提高消防管道30在电池10中的安装稳定性。
可选地，在该单卡爪结构的第一限位部310中，连接部311可以连接于消防管道30中远离电池单体20的一端。作为示例，如图6所示，消防管道30的截面可为跑道形，消防管道30中远离电池单体20的管壁为平行于第二方向y的平板状结构，该部分管壁可称之为消防管道的第一管壁，连接部311可为该第一管壁在第二方向y上的延伸部。通过该实施方式，可以利用消防管道30在第一方向x上厚度空间，设置与连接部311相互连接且朝向电池单体20延伸的第一卡爪部312，对应的，与第一卡爪部312相互卡接的第二限位部410也可设置于该消防管道30在第一方向x上厚度空间，从而节省消防管道30在电池单体20上的安装空间，有利于降低电池10的整个体积从而提升电池10的能量密度。
作为示例而非限定，如图6所示，第一卡爪部312可包括第一凸起，对应的，第二限位部410可包括第二凸起，该第一凸起和第二凸起可相互配合以实现第一卡爪部312与第二限位部410的相互卡接。
或者，在其它实施例中，第一卡爪部312与第二限位部410也可通过其它方式相互卡接。图7示出了本申请另一实施例提供的电池10的局部放大爆炸示意图。
如图7所示，在本申请实施例中，第二限位部410为卡槽结构，该卡槽结构包括沿第二方向y排列的第一卡槽壁411和第二卡槽壁412，该第一卡槽壁411与第二卡槽壁412用于夹持第一卡爪部312，以在第一方向x和第二方向y上对消防管道30进行限位。
具体地，在本申请实施例中，第二限位部410为配合于第一卡爪部312的卡槽结构，该卡槽结构中的第一卡槽壁411和第二卡槽壁412对第一卡爪部312进行夹持，可提高第一限位部310和第二限位部410之间的卡接强度，从而提升在第一方向x和第二方向y上对消防管道30的限位和固定效果，提高消防管道30在电池10中的安装稳定性。
可选地，为了使得第一卡槽壁411和第二卡槽壁412对第一卡爪部312起到良好的夹持效果，第一卡槽壁411和第二卡槽壁412在第二方向y上的距离适配于第一卡爪部312在第二方向y上的尺寸，例如：第一卡槽壁411和第二卡槽壁412在第二方向y上的距离与第一卡爪部312在第二方向y上的尺寸相等或相近。另外，第一卡槽壁411、第二卡槽壁412以及第一卡爪部312在第一方向x上的尺寸也可以相同或相近。
可选地，在本申请实施例的一些实施方式中，第一卡槽壁411、第二卡槽壁412以及第一卡爪部312均可为板状结构。当第一卡槽壁411和第二卡槽壁412形成的卡槽结构能够对第一卡爪部312进行稳固夹持时，卡槽结构的第二限位部410不仅可以在第二方向y上直接对第一卡爪部312起到较为可靠和稳定的限位和固定作用以外，还可以通过摩擦力在第一方向x上对第一卡爪部312起到一定程度的限位和固定作用。
或者，在本申请实施例的另一些实施方式中，为了进一步提高第二限位部410与第一卡爪部312在第一方向x上的卡接强度，以提高消防管道30在第一方向x上的限位和固定效果，在卡槽结构的第二限位部410中，第一卡槽壁411和/或第二卡槽壁412远离电池单体20的一端设置有第一凸起4101，第一卡爪部312靠近电池单体20的一端设置有第二凸起3121，该第一凸起4101与第二凸起3121相互配合，以在第一方向x上对消防管道30进行限位。
作为示例而非限定，如图7所示，第二卡槽壁412上设置有第一凸起4101，该第一凸起4101和第一卡爪部312上的第二凸起3121分别朝向第二方向y中相反的两个子方向凸出，且当第一卡爪部312安装于第一卡槽壁411和第二卡槽壁412之间后，第一凸起4101和第二凸起3121在第一方向x上相对设置，以使得该第一凸起4101和第二凸起3121能够相互配合卡接。另外，第一凸起4101设置于第二卡槽壁412远离电池单体20的一端，且第二凸起3121设置于第一卡爪部312靠近电池单体20的一端，当第二卡槽壁412与第一卡爪部312相互卡接后，第二凸起3121相对于第一凸起4101朝向电池单体20设置，该第一凸起4101能够防止第二凸起3121及其所在的第一卡爪部312远离电池单体20。
可以理解的是，在第一卡槽壁411设置有第一凸起4101的情况下，该第一卡槽壁411上的第一凸起4101和第一卡爪部312上的第二凸起3121也可分别朝向第二方向y中相反的两个子方向凸出。该第一凸起4101和第二凸起3121除了凸出方向与图7所示的凸出方向相反以外，其它相关技术方案可以参见上文相关描述，此处不做赘述。
另外，需要说明的是，在本申请实施例中，当第一卡爪部312安装于第一卡槽壁411和第二卡槽壁412之间后，第一凸起4101和第二凸起3121相对位置设计，只要使得第二凸起3121相对于第一凸起4101朝向电池单体20设置即可。因此，第一凸起4101除了可设置于第一卡槽壁411和/或第二卡槽壁412远离电池单体20的一端以外， 还可以设置于第一卡槽壁411和/或第二卡槽壁412的其它位置。第二凸起3121除了可设置于第一卡爪部312靠近电池单体20的一端以外，也可以设置于第一卡爪部312的其它位置。本申请实施例对第一凸起4101和第二凸起3121的具体位置不做限定。
可选地，在图7所示实施方式中，第一凸起4101和第二凸起3121均为块状凸起，当然，在其它实施方式中，该第一凸起4101和第二凸起3121也可为其它形状的凸起，本申请实施例对该第一凸起4101和第二凸起3121的形状也不做具体限定。
在本申请另一实施例中，第一卡爪部312上的第一凸起3121远离电池单体20的一端可设置有第一倾斜面3122，第一卡槽壁411和/或第二卡槽壁412上的第二凸起4101靠近电池单体20的一端设置有第二倾斜面4102，该第一倾斜面3122与第二倾斜面4102相互对应，且分别倾斜于垂直于第一壁201的所在平面。
在图7所示实施例的基础上，图8示出了本申请一实施例提供的电池10的一种局部放大示意图，其中，图8中的(a)图为局部放大爆炸示意图，图8中的(b)图为局部放大组装示意图。
如图8所示，第二卡槽壁412上的第二凸起4101靠近电池单体20的一端设置有第二倾斜面4102，第一卡爪部312上的第一凸起3121远离电池单体20的一端设置有第一倾斜面3122。当第一卡爪部312安装于第一卡槽壁411和第二卡槽壁412的过程中，第一倾斜面3122和第二倾斜面4102相对设置且能够滑动的相互附接，第一卡爪部312通过其第一倾斜面3122滑动接触于第二卡槽壁412的第二倾斜面4102，从而便于第一卡爪部312安装于第一卡槽壁411和第二卡槽壁412之间。
可选地，第一倾斜面4102和第二倾斜面3122可相互平行，以优化第一卡爪部312在第一卡槽壁411和第二卡槽壁412之间的滑动安装。
通过本申请实施例的技术方案，在第一卡爪部312设置有第一凸起3121，且第一卡槽壁411和/或第二卡槽壁412设置有与第一凸起3121相互配合的第二凸起4101的基础上，该第一凸起3121和第二凸起4101上可分别设置有相互配合的倾斜面，在保证第一卡爪部312与第一卡槽壁411和第二卡槽壁412能够具有较佳的卡接效果的同时，还能进一步提高第一卡爪部312在第一卡槽壁411和第二卡槽壁412之间的安装效率，从而在保证消防管道30在电池10中的安装稳定性的同时，提升消防管道30在电池10中的安装效率。
在图8所示实施例的基础上，图9示出了本申请一实施例提供的电池10的一种立体爆炸示意图。
如图9所示，在本申请实施例中，第二限位部410为卡槽结构，该卡槽结构沿第三方向z延伸，第一限位部310中的第一卡爪部312能够沿第三方向z在该卡槽结构中滑动，其中，第三方向z平行于电池单体20的第一壁201且平行于消防管道30的延伸方向。
具体地，在卡槽结构的第二限位部410中，第一卡槽壁411和第二卡槽壁412可沿第三方向z延伸，并在第三方向z上具有一定的长度，从而便于消防管道30中的第一卡爪部312能够沿第三方向z在该第一卡槽壁411和第二卡槽壁412之间滑动。
在电池单体20的运行过程中，由于其内部的化学反应，会造成电池单体20内 部的气体膨胀，使得电池单体20也会产生相应膨胀。当电池单体20在第三方向z上产生膨胀时，会引起位于其第一壁201的固定件40的位置变化，乃至引起该固定件40上的第二限位部410的位置变化。由于消防管道30中的第一卡爪部312能够沿第三方向z在该卡槽结构的第二限位部410中滑动，即使电池单体20的膨胀会引起第二限位部410的位置变化，但对消防管道30的影响较小或者没有影响，因此，即使电池单体20发生膨胀，消防管道30在电池10中安装稳定性仍然较高。
可选地，如图9所示，在电池单体20上的固定件40可包括多个第二限位部410。具体地，在第二方向y上，固定件40在对应于消防管道30的两侧的位置分别设置有第二限位部410，另外，在第三方向z上，固定件40在对应于消防管道30的同一侧的位置，也可设置有多个第二限位部410，以进一步加强对消防管道30的限位和固定作用。可选地，在第三方向z上，两个第二限位部410可分别设置于电池单体20的泄压机构213的两侧，固定件40在该两个第二限位部410之间留有开口，以供泄压机构213进行电池单体20内部的压力的泄放。
可以理解的是，图9仅作为示意而非限定的示出了本申请实施例中第二限位部410在固定件40上的数量和位置设置。该固定件40中具有对应于泄压机构213的开口，消防管道30对应于该泄压机构213以及该开口设置，因此，在本申请实施例中，第二限位部410能够设置于固定件40中除该开口以外，且能配合于消防管道30中第一限位部310的任意位置，本申请实施例对于固定件40上的第二限位部410的数量以及位置不做具体限定。
另外，在图9所示实施方式中，固定件40的两端可分别设置有环状安装部，通过该环状安装部与电池单体20中的电极端子214相互配合，可以实现固定件40在电池单体20上的固定安装。当然，除了该图9所示的实施方式以外，还可以通过其它机械固定方案实现固定件40在电池单体20上的固定安装，本申请实施例对于固定件40在电池单体20上的安装方式也不做具体限定。
请继续参见图9，可选地，在本申请实施例中，电池单体20中具有最大面积的壁朝向第三方向z设置，在该情况下，多个电池单体20可沿该第三方向z相互附接排列，可以提高多个电池单体20之间的稳定性。与此同时，消防管道30沿第三方向z，即多个电池单体20的排列方向延伸，可以对多个电池单体20同时起到消防和温度调节的作用。
另外，在图9所示实施例中，除了卡槽结构的第二限位部410沿第三方向z延伸以外，可选地，消防管道30中的第一限位部310也可沿第三方向z延伸。
在一些实施方式中，在第三方向z上，第一限位部310的延伸长度与消防管道30的延伸长度相同。通过该实施方式的技术方案，可以便于消防管道30通过其第一限位部310安装于多个不同位置的固定件40。作为一种示例，在不同类型的电池单体20中，电池单体20在第三方向z上的尺寸可能发生变化，因此，不同类型的电池单体20上的固定件40的位置也可能会发生相应变化。作为另一示例，在多个电池单体20中，可以仅在部分电池单体20的第一壁210上设置固定件40，在不同的应用需求下，固定件40在多个电池单体20上的位置也可能会发生调整和变化。在上述两种示例的情况 下，通过本申请实施例的技术方案，仍然可以利用该消防管道30上的第一限位部310与固定件40配合安装。换言之，消防管道30的固定安装不会因为多个电池单体20上固定件40的位置变化而产生影响。通过该实施方式的技术方案，不仅可以提高消防管道30在电池10中的安装效率，还可以使得消防管道30能够适用于更多的应用场景，有利于消防管道30在多种不同类型的电池10中的推广和使用。
而在另一些实施方式中，在第三方向z上，第一限位部310的延伸长度也可小于消防管道30的延伸长度。具体地，在第三方向z上，该第一限位部310的延伸长度匹配对应于第二限位部410的延伸长度。通过该实施方式的技术方案，也可以通过第一限位部310与第二限位部410实现消防管道30在电池10中的安装，并降低消防管道30整体的制造成本。
上文结合图5至图9说明了本申请一些实施例提供的电池10的技术方案，在上述申请实施例的技术方案中，消防管道30中的第一限位部310为单卡爪结构。下面结合图10至图14，说明本申请另一些实施例提供的电池10的技术方案，在下述申请实施例的技术方案中，消防管道30中的第一限位部310为双卡爪结构。
图10示出了本申请一实施例提供的电池10的另一截面爆炸示意图，图11示出了图10中B部分的局部放大示意图。
结合图10和图11所示，在本申请实施例中，消防管道30上的第一限位部310为双卡爪结构，该双卡爪结构包括：连接部311、沿第二方向y排列的第一卡爪部312和第二卡爪部313，连接部311由消防管道30的管壁沿第二方向y延伸形成，第一卡爪部312和第二卡爪部313连接于连接部311，并朝向电池单体20延伸；第一卡爪部312和第二卡爪部313用于夹持第二限位部410，以在第一方向x和第二方向y上对消防管道30进行限位。
可选地，如图11所示，消防管道30在第二方向y上的两侧分别设置有第一限位部310，即消防管道30在第二方向y上的两侧分别设置有双卡爪结构，利用消防管道30两侧的双卡爪结构夹持于第二限位部410，能够进一步提高消防管道30在电池10中的安装稳定性。
通过本申请实施例的技术方案，在消防管道30上设置双卡爪结构的第一限位部310，该双卡爪结构用于夹持固定件40上的第二限位部410，以实现消防管道30在电池10中的安装。具体的，当双卡爪结构夹持于第二限位部410后，双卡爪结构可在第二方向y中的两个相反的子方向上均对第二限位部410实现良好的限位和固定效果，使得消防管道30在第二方向y上具有较高的稳定性。再者，双卡爪结构夹持第二限位部410时，双卡爪结构与第二限位部410之间可具有第一方向x上的相互作用力，以保证消防管道30在第一方向x上也具有一定的稳定性。
可选地，在该双卡爪结构的第一限位部310中，连接部311可以连接于消防管道30中远离电池单体20的一端。作为示例，如图11所示，消防管道30的截面可为跑道形，消防管道30中远离电池单体20的管壁为平行于第二方向y的平板状结构，该部分管壁可称之为消防管道的第一管壁，连接部311可为该第一管壁在第二方向y上的延伸部。通过该实施方式，可以利用消防管道30在第一方向x上厚度空间，设置与连接 部311相互连接且朝向电池单体20延伸的第一卡爪部312和第二卡爪部313，对应的，夹持于第一卡爪部312和第二卡爪部313之间的第二限位部410也可设置于该消防管道30在第一方向x上厚度空间，从而节省消防管道30在电池单体20上的安装空间，有利于降低电池10的整个体积从而提升电池10的能量密度。
可选地，在图11所示实施方式中，第一卡爪部312和第二卡爪部313可为板状结构，对应的，第二限位部410也可为板状结构。在第二方向y上，该第一卡爪部312和第二卡爪部313之间的距离可与第二限位部410的尺寸相近，以使得第一卡爪部312和第二卡爪部313实现对第二限位部410的可靠夹持，提升消防管道30在电池10中的安装可靠性。另外，第一卡爪部312、第二卡爪部313以及第二限位部410在第一方向x上的尺寸也可以相同或相近，在第一方向x上，通过该实施方式，可以充分利用三者在第一方向x上的尺寸，增大第二限位部410在第一卡爪部312和第二卡爪部313之间摩擦力，从而进一步提升消防管道30在电池10中的安装可靠性。
在图11所示实施例的基础上，图12示出了本申请一实施例提供的电池10的另一局部放大爆炸示意图。
如图12所示，在本申请实施例中，第二限位部410为卡扣结构，该卡扣结构包括沿第一方向x排列的第一卡扣部413和第二卡扣部414，该第一卡扣部413由固定件40沿远离电池单体20的方向延伸形成，第二卡扣部414设置于第一卡扣部413远离电池单体20的一端，在第二方向y上，第二卡扣部414的尺寸不小于第一卡扣部413的尺寸，另外，在消防管道30的双卡爪结构的第一限位部310中，第一卡爪部312和/或第二卡爪部313卡接于该第二卡扣部414。
具体地，在本申请实施例中，在固定件40中，第二限位部410为包括第一卡扣部413和第二卡扣部414的卡扣结构，相对于第一卡扣部413，第二卡扣部414朝向消防管道30设置，且该第二卡扣部414在第二方向y上的尺寸不小于第一卡扣部413在第二方向y上的尺寸。因此，利用该尺寸较大的第二卡扣部414，可以易于实现该第二卡扣部414在消防管道30的双卡爪结构中的卡接，且提高该第二卡扣部414在双卡爪结构中的卡接强度。
作为示例而非限定，在一些实施方式中，在消防管道30的双卡爪结构的第一限位部310中，第一卡爪部311和/或第二卡爪部312靠近电池单体20的一端设置有第三凸起3101，第二卡扣部414包括沿第二方向y相对于第一卡扣部413突出的第四凸起4141，该第四凸起4141与第三凸起3101相互配合，以在第一方向x上对消防管道30进行限位。通过该实施方式的技术方案，可以提高第二卡扣部414与双卡爪结构在第一方向x上卡接强度。
例如，在图12所示实施方式中，第一卡爪部311和第二卡爪部312靠近电池单体20的一端均设置有第三凸起3101，且该两个第三凸起3101沿第二方向y排列且相对设置。对应于该两个第三凸起3101，在第二限位部410中远离电池单体20的一端，第二卡扣部414置有两个第四凸起4141，该两个第四凸起4141分别位于第二卡扣部414在第二方向y上的两侧。
通过图12所示的实施方式，当第二卡扣部414安装于第一卡爪部312和第二卡 爪部313之间后，每个第三凸起3101与其对应的第四凸起4141在第一方向x上相对设置，以使得该第三凸起3101和第四凸起4141能够相互配合卡接。另外，第三凸起3101设置于第一限位部310靠近电池单体20的一端，且第四凸起4141设置于第二限位部410远离电池单体20的一端，当第一限位部310与第二限位部410相互卡接后，第四凸起4141相对于第三凸起3101朝向电池单体20设置，该第四凸起4141能够防止第三凸起3101及其所在的双卡爪结构远离电池单体20。
可以理解的是，除了如图12所示实施方式以外，第三凸起3101可仅设置于第一卡爪部312和第二卡爪部313中的其中一个，对应的，第二卡扣部414也可仅在其第二方向y上的一侧设置第四凸起4101，通过该实施方式，也可以实现双卡爪结构与第二卡扣部414在第一方向x上的相互卡接。
另外，需要说明的是，在本申请实施例中，当第二卡扣部414安装于第一卡爪部312和第二卡爪部313之间后，第三凸起3101和第四凸起4141相对位置设计，只要使得第四凸起4141相对于第三凸起3101朝向电池单体20设置即可。因此，第四凸起4141除了可设置于第二限位部410远离电池单体20的一端以外，还可以设置于第二限位部410的其它位置。第三凸起3101除了可设置于第一卡爪部312和/或第二卡爪部313靠近电池单体20的一端以外，也可以设置于第一卡爪部312和/或第二卡爪部313的其它位置。本申请实施例对第三凸起3101和第四凸起4141的具体位置不做限定。
可选地，在图12所示实施方式中，第三凸起3101和第四凸起4141均为块状凸起，当然，在其它实施方式中，该第三凸起3101和第四凸起4141也可为其它形状的凸起，本申请实施例对该第三凸起3101和第四凸起4141的形状也不做具体限定。
在本申请另一实施例中，第三凸起3101靠近电池单体20的一端设置有第三倾斜面3102，第四凸起4141远离电池单体20的一端设置有第四倾斜面4142，该第三倾斜面3102与第四倾斜面4142相互对应，且分别倾斜于垂直于电池单体20的第一壁201的所在平面。
在图12所示实施例的基础上，图13中示出了本申请一实施例提供的电池10的另一局部放大示意图，其中，图13中的(a)图为局部放大爆炸示意图，图13中的(b)图为局部放大组装示意图。
如图13所示，第二卡扣部414上的第四凸起4141靠近电池单体20的一端设置有第四倾斜面4142，第一卡爪部312和第二卡爪部313上的第三凸起3101远离电池单体20的一端设置有第三倾斜面3102。当第二卡扣部414安装于第一卡爪部312和第二卡爪部313的过程中，第三倾斜面3102和第四倾斜面4142相对设置且能够滑动的相互附接，第一卡爪部312和第二卡爪部313通过其第三倾斜面3102滑动接触于第二卡扣部414的第四倾斜面4142，从而便于第二卡扣部414安装于第一卡爪部312和第二卡爪部313之间。
可选地，第三倾斜面3102和第四倾斜面4142可相互平行，以优化第二卡扣部414在第一卡爪部312和第二卡爪部313之间的滑动安装。
通过本申请实施例的技术方案，在第一卡爪部312和/或第二卡爪部313设置有第三凸起3101，且第二卡扣部414设置有与第三凸起3101相互配合的第四凸起4141的 基础上，该第三凸起3101和第四凸起4141上可分别设置有相互配合的倾斜面，在保证第二卡扣部414与第一卡爪部312和第二卡爪部313能够具有较佳的卡接效果的同时，还能进一步提高第二卡扣部414在第一卡爪部312和第二卡爪部313之间的安装效率，从而在保证消防管道30在电池10中的安装稳定性的同时，提升消防管道30在电池10中的安装效率。
在图13所示实施例的基础上，图14示出了本申请一实施例提供的电池10的另一立体爆炸示意图。
如图14所示，在本申请实施例中，第一限位部310为双卡爪结构，该双卡爪结构沿第三方向z延伸，固定件40中的第二限位部410能够沿第三方向z在该双卡爪结构中滑动，其中，第三方向z平行于电池单体20的第一壁201且平行于消防管道30的延伸方向。
具体地，双卡爪结构的第一限位部310中，第一卡爪部312和第二卡爪部313可沿第三方向z延伸，并在第三方向z上具有一定的长度，从而便于固定件40中的第二限位部410能够沿第三方向z在该第一卡爪部312和第二卡爪部313之间滑动。
在电池单体20的运行过程中，由于其内部的化学反应，会造成电池单体20内部的气体膨胀，使得电池单体20也会产生相应膨胀。当电池单体20在第三方向z上产生膨胀时，会引起位于其第一壁201的固定件40的位置变化，乃至引起该固定件40上的第二限位部410的位置变化。由于第二限位部410能够沿第三方向z在第一限位部310的第一卡爪部312和第二卡爪部313之间滑动，即使电池单体20的膨胀会引起第二限位部410的位置变化，但对消防管道30的影响较小或者没有影响，因此，即使电池单体20发生膨胀，消防管道30在电池10中安装稳定性仍然较高。
可选地，如图14所示，在本申请实施例中，除了双卡爪结构的第一限位部310沿第三方向z延伸以外，可选地，固定件40中的第二限位部410也可沿第三方向z延伸，从而提高第二限位部410与双卡爪结构之间的安装可靠性。
另外，对于本申请实施例中固定件40，除了其第二限位部410的结构不同于图9所示的技术方案以外，该固定件40的其它相关技术方案，可以参见上文图9所示实施例的相关描述，此处不做具体赘述。
可选地，作为示例而非限定，在图14所示实施方式中，在第三方向z上，双卡爪结构的第一限位部310的延伸长度与消防管道30的延伸长度相同。而在另一些实施方式中，在第三方向z上，双卡爪结构的第一限位部310的延伸长度也可小于消防管道30的延伸长度。具体地，在第三方向z上，该第一限位部310的延伸长度匹配对应于第二限位部410的延伸长度。
参照上文图9所示实施方式的相关描述，在第一限位部310在第三方向z上的延伸长度与消防管道30在第三方向z上的延伸长度相同的情况下，可以便于消防管道30通过其第一限位部310安装于多个不同位置的固定件40，从而提高消防管道30在电池10中的安装效率，还可以使得消防管道30能够适用于更多的应用场景，有利于消防管道30在多种不同类型的电池10中的推广和使用。在第一限位部310在第三方向z上的延伸长度小于消防管道30在第三方向z上的延伸长度的情况下，可以降低消防管道 30整体的制造成本。
综合上述图4至图14所示实施例的技术方案，在本申请中，消防管道30可包括至少一对第一限位部310，在第二方向y上，每对第一限位部310分别位于消防管道30的两侧，固定件40可包括至少一对第二限位部410，每对第二限位部410与每对第一限位部310对应设置。
可选地，消防管道30可包括一对第一限位部310，在第二方向y上，该一对第一限位部310分别位于消防管道30的两侧，且该一对第一限位部310在第三方向z上的延伸长度小于或等于消防管道30的延伸长度。在该实施方式下，固定件40包括至少一对第二限位部410，该至少一对第二限位部410中每对第二限位部410对应位于消防管道30在第二方向y上的两侧，且该每对第二限位部410均与该一对第一限位部310对应设置。
可选地，消防管道30可包括多对第一限位部310，在第二方向y上，该多对第一限位部310中的每对第一限位部310分别位于消防管道30的两侧，该每对第一限位部310在第三方向z上的延伸长度小于消防管道30的延伸长度。在该实施方式下，固定件40包括多对第二限位部410，该多对第二限位部410中每对第二限位部410对应位于消防管道30在第二方向y上的两侧，在第三方向z上，该多对第二限位部410可以与多对第一限位部310一一对应设置。
通过本申请实施例的技术方案，消防管道30在第二方向y上的两侧设置有至少一对第一限位部310，该至少一对第一限位部310通过与其对应的至少一对第二限位部410相互配合，实现对消防管道30在第二方向y上较为可靠和稳定的限位和固定，从而提升消防管道30在电池10中的安装稳定性。
除了上述申请实施例的技术方案以外，在另一些实施方式中，第一限位部310也可不设置于消防管道30在第二方向y上的两侧，而设置在消防管道30朝向电池单体20的一侧，即设置在消防管道30在第一方向x上的一侧。或者，第一限位部310也可设置于消防管道30在第三方向z上的两侧。本申请实施例对第一限位部310在消防管道30上的具体位置和数量不做具体限定，旨在能够实现第一限位部310与固定件40上第二限位部410相互配合，以实现消防管道30在电池10中的稳定安装即可。
另外，在本申请中，第一限位部310除了可以上文申请实施例中所述的单卡爪结构或是双卡爪结构以外，第一限位部310还可以为三卡爪结构或者为更多数量的卡爪结构，以进一步增强消防管道30在电池10中的安装稳定性。在该情况下，多卡爪结构中每个卡爪可以参见上文实施例的相关技术方案，且多卡爪结构对应的第二限位部410也可以参见上文实施例的相关技术方案，此处不再做过多赘述。
图15示出了本申请一实施例提供的电池10的另一立体爆炸示意图。
如图15所示，电池10包括多个沿第三方向z相互附接排列的电池单体20，消防管道30沿该第三方向z延伸，并与该多个电池单体20中的泄压机构213对应设置。
可选地，如图15所示，在沿第三方向z排列的一列电池单体20中，仅部分电池单体20与消防管道30之间设置有固定件40。该消防管道30上设置有第一限位部310，且固定件40上设置有第二限位部410，该第一限位部310和第二限位部410的相 关技术方案可以参见上文图4至图14中任一实施例中的技术方案。
通过该实施方式的技术方案，可以在保证消防管道30在电池10中的固定稳定性的同时，可以减少电池10中固定件40的数量，从而降低电池10的制造成本。
可选地，在图15所示实施方式中，设置有固定件40的电池单体20之间间隔至少一个未设置固定件40的电池单体。在该实施方式中，固定件40的尺寸可设计的较大，例如，在第三方向z上，该固定件40除了可设置在其所在电池单体20的第一壁201以外，还可以设置在与其所在电池单体20相邻的电池单体20的第一壁201。因此，通过该实施方式的技术方案，一方面，可以利用较大尺寸的固定件40实现固定件40在电池单体20上较为稳定和可靠的固定；另一方面，该较大尺寸的固定件40上也可设置较大尺寸的第二限位部410，以提高第二限位部410与消防管道30上第一限位部310之间的安装可靠性，从而提高消防管道30在电池10中的安装稳定性。
可以理解的是，在图15所示的电池10中，电池10还可以进一步包括箱体100，用于容纳多个电池单体20。例如，在图15所示的箱体100中，其可用于容纳沿第二方向y排列的两列电池单体20，每列电池单体20中的多个电池单体20沿第三方向z排列。作为示例，图15中仅示意了两列电池单体20中的其中一列。
还可以理解的是，上文图4至图8，以及图10至图13中的截面示意图可以为图15中沿C-C’方向的截面示意图，上文图9和图14所示的立体示意图可以为图15中的局部立体图。换言之，上文图4至图14中任一申请实施例的技术方案均可应用于图15所示的申请实施例中。
在上文申请实施例中，消防管道30的管壁可为厚度均匀的管壁，在该实施方式下，消防管道30的制造方式较为便捷，且制造工艺也相对成熟。
可选地，为了进一步增加消防管道30的强度，提升消防管道30的抗冲击能力，以保障消防管道30在电池10中的消防和温度调节功能，消防管道30中至少部分管壁的厚度可以设计的较厚。
在一些可能的实施方式中，消防管道30包括沿第一方向x相对设置的第一管壁301和第二管壁302，第一管壁301相对于第二管壁302更远离电池单体20，其中，第一管壁301的厚度大于第二管壁302的厚度，和/或，第一管壁301设置有加强件50。
图16示出了本申请一实施例提供的消防管道30的一种结构示意图，其中，图16中的(a)图为消防管道30的一种立体结构示意图，图16中的(b)图为(a)图所示的消防管道30的一种截面示意图。
作为示例而非限定，在图16中，消防管道30的截面近似为跑道形，其中，沿第一方向x相对设置的第一管壁301和第二管壁302可为平板状结构，该第一管壁301在第一方向x上的厚度大于第二管壁302在第一方向x上的厚度。
需要说明的是，在其它实施方式中，消防管道30还可以为其它形状的管道，例如圆形管道、四边形管道或者多边形管道等等，在该实施方式下，消防管道30的管壁同样可包括沿第一方向x相对设置的第一管壁301和第二管壁302，该第一管壁301和第二管壁302可以为平板状结构、曲面板状结构或者还可以为其它形状结构，本申请实施例对该消防管道30、第一管壁301和第二管壁302的具体形状结构不做限定。
通过本申请实施例的技术方案，在消防管道30中，远离电池单体20的第一管壁301的厚度大于靠近电池单体20的第二管壁302的厚度，因此，远离电池单体20的第一管壁301的厚度较大且其具有较高的强度，能够较大程度的承受外力对消防管道30造成的冲击，提升消防管道30在电池10中的可靠性。与此同时，当电池单体20内的排放物经过泄压机构213排放时，一方面，排放物可以较为容易的冲破厚度较小的第二管壁302，使得消防管道30中的消防介质排出从而起到消防作用，另一方面，当排放物通过第二管壁302到达第一管壁301时，具有较大厚度以及较高强度的第一管壁301能够承受该排放物的冲击，该第一管壁301不易被排放物冲破，因而能够避免消防管道30中的消防介质从第一管壁301中的缺口排出，避免造成消防介质不必要的浪费，从而提升消防管道30的消防效果。
可选地，在图16所示实施方式中，第一管壁301包括远离电池单体20方向的凸起，通过该凸起的设置，可以实现第一管壁301的厚度大于第二管壁302的厚度。在该实施方式中，第一管壁301的厚度设计不会影响消防管道30中用于容纳消防介质的管道容量。当然，在其它实施方式中，为了节约消防管道30所需占用的安装空间，该第一管壁301也可适当朝向消防管道30的内部凸起。另外，在图16所示实施方式中，第一管壁301的截面近似为梯形，在其它实施方式中，该第一管壁301的截面还可以为四边形或者其它形状，本申请实施例对该第一管壁301的截面的具体形状不做具体限定。
图17示出了本申请一实施例提供的消防管道30的另一结构示意图，其中，图17中的(a)图为消防管道30的一种立体结构示意图，图17中的(b)图为(a)图所示的消防管道30的一种截面示意图。
如17所示，在本申请实施例提供的消防管道30中，第一管壁301设置有加强件50。可选地，第一管壁301在远离电池单体20方向的一侧设置有加强件50，该加强件50的设置不会影响消防管道30内的管道容量。
可选地，该加强件50可为条状结构。在一些相关技术中，该条状结构的加强件50也可称之为加强筋。通过在第一管壁301上设置加强件50，同样可以提高第一管壁301的强度，以提高第一管壁301的耐冲击能力，提升消防管道30在电池10中的使用可靠性。
作为示例而非限定，在图17所示实施方式中，加强件50包括沿第二方向y延伸的至少一个第一加强件，该至少一个第一加强件沿第三方向z排列；和/或，沿第三方向z延伸的至少一个第二加强件，该至少一个第二加强件沿第二方向y排列。
可选地，在一些实施方式中，该第一加强件在第二方向y上的尺寸可以与第一管壁301在第二方向y上的尺寸相近或相同。可选地，在另一些实施方式中，如图17所示，该第一加强件可以进一步覆盖第一限位件310中的连接部311，即第一加强件在第二方向y上的尺寸可以与第一管壁301与连接部311在第二方向y上的尺寸之和相近或相同。通过该至少一个第一加强件的设置可以提高第一管壁301在第二方向y上的强度。
类似地，第二加强件在第三方向z上的尺寸可以与第一管壁301在第三方向z 上的尺寸相近或相同。该至少一个第二加强件的设置可以提高第一管壁301在第三方向z上的强度。
可以理解的是，为了较大程度的提高第一管壁301的强度，在另一些实施方式中，第一管壁301在具有较大的厚度的同时可进一步设置加强件50。即综合图16和图17所示实施例的方案，能够得到具有较高强度的消防管道30。
图18示出了本申请一实施例提供的消防管道30的另一结构示意图，其中，图18中的(a)图为消防管道30的一种立体结构示意图，图18中的(b)图为(a)图所示的消防管道30的一种截面示意图。
如图18所示，在本申请实施例中，在第二方向y上，第一管壁301的尺寸大于第二管壁302的尺寸。
作为示例而非限定，在图18所示实施例中，消防管道30的截面可为倒梯形，第一管壁301在第二方向y上的尺寸可大于第二管壁302在第二方向y上的尺寸。
通过图18所示实施例的技术方案，在消防管道30中，通过设计第一管壁301与第二管壁302在第二方向y上的尺寸，也可以使得第一管壁301的强度强于第二管壁302，即第一管壁301可具有较高的强度，能够较高程度的承受外力对消防管道30造成的冲击，提升消防管道30在电池10中的使用可靠性。另外，当电池单体20内部的排放物经过泄压机构213冲击第二管壁302时，可能会使得第二管壁302整体贴附于第一管壁301，当第一管壁301与第二管壁302的尺寸相同时，该相互贴附的第二管壁302与第一管壁301会阻塞流道，从而阻碍消防管道30中的消防介质流入对应的泄压机构213以及电池单体20内部，影响消防管道30的消防效果。而通过本申请实施例的技术方案，第一管壁301在第二方向y上的尺寸大于第二管壁302在第二方向y上的尺寸，即使第二管壁302贴附于第一管壁301，也不会完全阻塞流道，可以使得消防介质流入对应的泄压机构213以及电池单体20内部，以起到良好的消防作用。
可选地，在图18所示实施例中，消防管道30的第一管壁301可同时采用上述图16和/或图17的技术方案，即第一管壁301的厚度大于第二管壁302的厚度，和/或，第一管壁301设置有加强件50，以进一步提高第一管壁301的强度。
需要说明的是，上文图16至图18中，消防管道30中的第一限位部310以图8中所示的第一限位部310进行了举例示意，该图16至图18中的第一限位部310还可以为上文图4至图15中任一实施例中的第一限位部310。换言之，图16至图18所示实施例中，第一管壁301、第二管壁302以及加强件50的相关技术方案可以应用于上文图4至图15中任一实施例。
本申请一个实施例还提供了一种用电装置，该用电装置可以包括前述实施例中的电池10，电池10用于向该用电装置提供电能。
可选地，用电装置可以为车辆1、船舶或航天器。
上文描述了本申请实施例的电池10和用电装置，下面将描述本申请实施例的制备电池的方法和装置，其中未详细描述的部分可参见前述各实施例。
