Description

绝缘件、端盖组件、储能装置和用电设备 技术领域
本申请涉及储能技术领域，具体涉及一种绝缘件、端盖组件、储能装置和用电设备。
背景技术
二次电池(Rechargeable battery)又称为充电电池或蓄电池，是指在电池放电后可通过充电的方式使活性物质激活而继续使用的电池。二次电池的可循环利用特性使其逐渐成为用电设备的主要动力来源，随着二次电池的需求量逐渐增大，人们对其各方面的性能要求也越来越高，尤其是对于电池单位体积能量密度的要求，而电池的端盖组件的厚度是影响电池单位体积能量密度的重要参数，端盖组件过厚则降低电池单位体积的能量密度。
目前的端盖组件包括用于顶盖和极柱之间进行绝缘的绝缘件，现有绝缘件所处位置的气体流动较为混乱，无法为防爆阀提供更大的气压环境；并且，由于绝缘件较薄的设计，还导致绝缘件不易脱模且结构强度不足。所以如何解决绝缘件内气压混乱和强度不足成为了关键问题。
发明内容
本申请的目的是提供一种可提高安全性能的绝缘件、端盖组件、储能装置和用电设备。
为实现本申请的目的，本申请提供了如下的技术方案：
第一方面，本申请提供一种绝缘件，包括主体板、第一边条、凸台、第一支撑条和第二支撑条；主体板在其厚度方向上包括相背的第一表面和第二表面；第一边条位于所述主体板的长度方向上的一端，且与所述主体板之间具有间隔距离，所述第一边条相背的两端与所述主体板为圆角连接；凸台位于所述主体板和所述第一边条之间，所述凸台凸出于所述第一表面；第一支撑条和第二支撑条设置于所述主体板和所述第一边条之间，所述第一支撑条和所述第二支撑条在所述主体板的宽度方向上相对间隔设置；所述第一支撑条和所述第二支撑条为弧形，且所述第一支撑条朝背向所述第二支撑条的方向突出，所述第二支撑条朝背向所述第一支撑条的方向突出；在所述主体板的厚度方向上，所述第一支撑条和所述第二支撑条的一端连接所述凸台，所述第一支撑条和所述第二支撑条的壁厚沿远离所述凸台的方向逐渐减小；所述主体板、所述第一边条、所述凸台、所述第一支撑条和所述第二支撑条为一体成型结构。
本申请通过设置第一支撑条和第二支撑条均为弧形，一方面使得支撑条能够适配防爆阀；另一方面，位于第一支撑条和第二支撑条之间的气流在二者的引导下，能够形成涡流状在防爆阀的下侧汇聚，从而在储能装置内部的气压增大时，呈涡流状汇聚的气流能够产生更大的气压，从而加快开阀速度；还通过设置第一支撑条和第二支撑条的壁厚逐渐减小，使得第一支撑条和第二支撑条与凸台连接处的接触面更大，能够减小电芯向上挤压时对应第一支撑条和第二支撑条位置的凸台所受到的压强，从而避免凸台差异化受力过大导致开裂并划伤极芯，提高绝缘件的结构稳定性和结构强度；另一方面，注塑时第一支撑条和第二支撑条的位置对应为注塑用的流道，第一支撑条和第二支撑条壁厚较宽的位置可以便于更多的塑胶液快速通 过且成型，避免第一支撑条和第二支撑条与凸台的连接处缺胶或者形成熔接痕，以此提高生产良率和效率。由于第一支撑条和第二支撑条均为圆弧形，而因为注塑冷却后圆弧形结构会出现收缩箍紧膜具凸块的现象。所以，设置第一支撑条和第二支撑条为上窄下宽的结构方便圆弧形筋脱膜，与模具凸块分离。
一种实施方式中，所述凸台包括第一连接部、第二连接部和透气板，所述第一连接部和所述第二连接部在所述主体板的宽度方向上相对间隔设置，所述第一连接部和所述第二连接部凸出于第一表面，透气板相背的两端分别连接所述第一连接部和所述第二连接部，所述透气板包括朝向所述第一表面的第三表面，所述第一支撑条和所述第二支撑条连接在所述第三表面上，所述透气板上设有透气孔。
通过设置第一连接部和第二连接部连接在透气板相对的两端，并设置第一连接部和第二连接部为突出第一表面的结构，使得透气板所在的平面相较于低于主体板所在的平面，从而为容置防爆阀、第一限位条和第二限位条提供的空间；进一步的，第一连接条和第二连接条连接在透气板的第三表面上，可以提高透气板在和主体板之间的结构强度，提高透气板的抗压能力。
一种实施方式中，所述第一支撑条和所述第二支撑条为镜像对称，所述第一支撑条包括第一支撑部和第二支撑部，所述第二支撑部相背离的两端分别连接所述第一支撑部和所述透气板；在所述主体板的长度方向上，所述第二支撑部的直线长度小于等于所述透气板的长度。
通过设置第二支撑部的直线长度小于等于透气板的长度，使得上述中的第一气流槽和第二气流槽在宽度方向上没有阻挡，气体能够在第一气流槽和第二气流槽中实现纵向流动；并且由于第一支撑条和第一连接部之间具有间隔距离，使得第一气流槽和第二气流槽能够通过第一支撑条和第一连接部之间的间距连通，在第一支撑条和第二支撑条均为环形的情况下，能够在防爆阀的外周形成类圆环型的气流通道(以下简称环形气道)。进一步的，该环形气道的优势在于，在储能装置为常压状态下，环形气道更有利于气体循环；而在增压情况下，环形气道更有利于气体形成涡流然后向防爆阀形成汇流。
一种实施方式中，所述凸台在所述主体板的宽度方向上包括相背第一外侧面和第二外侧面，所述第一外侧面位于所述第一连接部，所述第二外侧面位于所述第二连接部，所述第一外侧面和所述第二外侧面的形状均为正梯形，所述第一外侧面和所述第二外侧面连接所述主体板的一边为长顶边，连接所述透气板的一边为短顶边。
通过设置第一连接部和第二连接为梯形截面的结构，有利于在制造时利用一对梯形动模具和梯形定模具配合注塑，且在梯形模具无需高精度操作对准便可完成互相快速卡合，并且密封性较强，能够避免溢胶，进一步提升产品生产效率和良率；同时，由于连接主体板的一侧为长顶边，能够加强第一连接部和第二连接与主体板之间的连接强度，从而提高绝缘件整体的结构稳固性。
一种实施方式中，所述透气板在所述主体板的长度方向上还包括相背离的第一边缘和第二边缘，所述第一边缘与所述主体板之间具有间隔距离，所述第二边缘与所述第一边条之间具有间隔距离。
通过设置主体板的第一边缘与主体板之间具有间隔距离，第二边缘与第一边条之间具有间隔，提高了气流流至防爆阀处的气体通道数量，从而使得储能装置内的气体可以快速的在防爆阀的附近流动，以此在储能装置内部产气后，气体能够顺利的抵达防爆阀处从而将防爆阀冲破。
一种实施方式中，在所述主体板的长度方向上，所述第一边缘到所述第二边缘的距离小 于所述主体板到所述第一边条的距离。通过设置第一边缘到第二边缘的距离小于主体板到第一边条的距离，使得第一边缘和主体板之间的距离，以及第二边缘和第一边条之间的距离更大，从而形成更大的气流槽，在电芯产气后，气体能够通过所形成的气流槽快速汇聚到防爆阀的下端，从而实现快速相应的目的。
一种实施方式中，所述主体板、所述透气板和所述第一边条满足关系式：0.85≤S1/S2≤1.15，其中，S1为所述第一边缘到所述主体板的最小距离，S2为所述第二边缘到所述第一边条的最小距离。
将S1和S2之间的比值设定在上述外围内，可以确保所形成的第一气流槽和第二气流槽的槽宽相近，以此使得防爆阀两侧的气流相近。该设计可以防止经过第一气流槽和第二气流槽的气体由于流量不均而产生的气压差，在搬运储能装置的过程种，或受外力冲击的情况中，能够避免产生气压差而导致的误开防爆阀的现象。
一种实施方式中，所述透气孔的数量为多个，多个所述透气孔呈多行多列排布。通过在透气板上开设多个透气孔，有利于增加防爆阀处的气体流量，从而提高防爆阀的响应速度。
一种实施方式中，多个所述透气孔分为第一透气孔组、第二透气孔组和第三透气孔组，所述第一透气孔组、所述第二透气孔组和所述第三透气孔组沿所述主体板的宽度方向依次排布，所述第一透气孔组和所述第三透气孔组中的透气孔数量相同，所述第一透气孔组中的透气孔数量小于所述第二透气孔组中的透气孔数量，所述第二透气孔组与所述防爆阀对应。
通过划分多个透气孔为第一透气孔组、第二透气孔组和第三透气孔组，且设置具有较多透气孔的第二透气孔组与防爆阀对应，使得防爆阀和透气板之间的气体能够快速汇聚；并且，第一透气孔组和第三透气孔组的透气孔数量相同，使得汇流至环形气道的气体为均匀的，不会产生气压差而导致破坏环形气道的情况。
一种实施方式中，所述第一支撑条和所述第二支撑条均与所述透气板连接，所述第一支撑条与所述透气板的连接点位于所述第一透气孔组和所述第二透气孔组之间，所述第二支撑条与所述透气板的连接点位于所述第二透气孔组和所述第三透气孔组之间。
通过设置第二透气孔组位于第一支撑条和第二支撑条之间，使得经第二透气孔组流至防爆阀下侧的气流不会在短时间内流出，从而能够提高气体的汇聚效率，从而进一步提高防爆阀的响应速度。
一种实施方式中，所述绝缘件还包括第二边条和第三边条，所述第二边条和所述第三边条均连接在所述主体板的同一侧，且所述第二边条和所述第三边条在所述宽度方向上相对间隔设置，所述第一边条相背离的两端分别与所述第二边条和所述第三边条为圆角连接；所述第一边条、所述第二边条和所述第三边条满足关系式：0.8≤R1/R2≤1.2，1.8mm≤R1≤2.2mm；其中，R1为所述第一边条和所述第二边条连接所形成的圆角的半径，R2为所述第一边条和所述第三边条连接所形成的圆角的半径。
通过设置第一边条相背的两端与主体板为圆角连接的优势在于，能够减少储能装置在安装时的有害摩擦，避免绝缘件部分过于尖锐而磨破转接件。
一种实施方式中，所述绝缘件还包括沉台，所述沉台连接在所述主体板远离所述凸台的一端，所述沉台凸出于所述第一表面，所述沉台包括背向所述第二外侧面的第三外侧面，所述第三外侧面与所述第一外侧面的朝向相同。
一种实施方式中，在所述第一外侧面上具有注塑工艺留下的第一注塑部，在所述第三外侧面上具有注塑工艺留下的第二注塑部。
本申请通过设置第一注塑部位于凸台的第一外侧面，使得熔化的塑胶液流动方向为主体 板的宽度方向，可以将注塑模具的脱模方向沿着主体板的厚度方向设置，注塑口位于模具上方，塑胶液可以在重力作用下结合负压吸力双重引导，从上至下快速流动充满模腔；并且得益于塑胶液流动方向与凸台和第一边条的延伸方向一致，从而避免凸台和第一边条结构过长造成的塑胶液延不均匀的熔接痕现象；同时，结合上述中圆角连接的第一边条，使得在注塑时，塑胶液自上而下流经至第一边条的端部时，减少塑胶液以90度角撞击模具的内壁而形成涡流后产生的气泡，从而使得第一边条在弯角处的塑胶不会存在缺陷，提高第一边条在弯角处的结构强度。
通过在沉台的与凸台的同一侧设置第二注塑部，使得绝缘件在注塑成型时，可以利用第一注塑部和第二注塑部进行同时注液，一方面提高了绝缘件的制造速度，并且位于主体板两侧的注塑部中的塑胶液可以向主体板的中间汇流，从而提高绝缘件整体的均匀度；另一方面，塑胶液流动方向与沉台的延伸方向一致，从而避免沉台结构过长造成的塑胶液延不均匀的熔接痕现象。

由于人们所需要的能源都具有很强的时间性和空间性，为了合理利用能源并提高能量的利用率，需要通过一种介质或者设备，把一种能量形式用同一种或者转换成另外一种能量形式存储起来，基于未来应用需要再以特定能量形式释放出来。众所周知，要实现碳中和的大目标，目前绿色电能的产生主要途径是发展光伏、风电等绿色能源来替代化石能源。目前绿色电能的产生普遍依赖于光伏、风电、水势等，而风能和太阳能等普遍存在间歇性强、波动性大的问题，会造成电网不稳定，用电高峰电不够，用电低谷电太多，不稳定的电压还会对电力造成损害，因此可能因为用电需求不足或电网接纳能力不足，引发“弃风弃光”问题，要解决这些问题须依赖储能。即将电能通过物理或者化学的手段转化为其他形式的能量存储起来，在需要的时候将能量转化为电能释放出来，简单来说，储能就类似一个大型“充电宝”，在光伏、风能充足时，将电能储存起来，在需要时释放储能的电力。
以电化学储能为例，本方案提供一种储能装置，储能装置内设有一组化学电池，主要是利用化学电池内的化学元素做储能介质，充放电过程伴随储能介质的化学反应或者变化，简单说就是把风能和太阳能产生的电能存在化学电池中，在外部电能的使用达到高峰时再将存 储的电量释放出来使用，或者转移给电量紧缺的地方再使用。
目前的储能(即能量存储)应用场景较为广泛，包括(风光)发电侧储能、电网侧储能、基站侧储能以及用户侧储能等方面，对应的储能装置的种类包括有：
(1)应用在电网侧储能场景的大型储能集装箱，其可作为电网中优质的有功无功调节电源，实现电能在时间和空间上的负荷匹配，增强可再生能源消纳能力，并在电网系统备用、缓解高峰负荷供电压力和调峰调频方面意义重大。
(2)应用在用户侧的工商业储能场景(银行、商场等)的中小型储能电柜，主要运行模式为“削峰填谷”。由于根据用电量需求在峰谷位置的电费存在较大的价格差异，用户有储能设备后，为了减少成本，通常在电价低谷期，对储能柜/箱进行充电处理；电价高峰期，再将储能设备中的电放出来进行使用，以达到节省电费的目的。
请参考图1和图2，本申请实施例提供的储能装置应用于一种储能系统，该储能系统包括电能转换装置(光伏板200)、风能转换装置(风机300)、用电设备(电网400)以及储能装置100，该储能装置100可作为储能柜，可以安装于室外。具体的，光伏板200可以在电价低谷时期将太阳能转换为电能，储能装置100用于储存该电能并在用电高峰时供给电网400，或者在电网400断电/停电时进行供电。风能转换装置(风机300)可以将风能转换为电能，储能装置100用于储存该电能并在用电高峰时供给电网400，或者在电网400断电/停电时进行供电。其中，电能的传输可以采用高压线缆进行传输。
储能装置100的数量可以为数个，数个储能装置100相互串联或并联，数个储能装置100采用隔离板(图未示)进行支撑及电连接。本实施例中，“数个”是指两个及两个以上。储能装置100外部还可以设有储能箱，用于收容储能装置100。
可以理解的是，储能装置100可包括但不限于单体电池、电池模组、电池包、电池系统等。本申请实施例提供的储能装置的实际应用形态可以为但不限于为所列举产品，还可以是其他应用形态，本申请实施例不对储能装置100的应用形态做严格限制。本申请实施例仅以储能装置100为多芯电池为例进行说明。
请参考图2，储能装置100包括壳体40、电芯组件30、转接件20和端盖组件10。电芯组件30包括电芯301、正极耳302和负极耳303，正极耳302和负极耳303分别与电芯301相连。电芯组件30设置在壳体40内，转接件20连接电芯组件30和端盖组件10，端盖组件10封闭壳体40的开口。转接件20包括正极侧的转接件(即第一转接件201)和负极侧的转接件(即第二转接件202)，端盖组件10与第一转接件201和第二转接件202相连，并连接壳体40的开口处封闭壳体40。
端盖组件10包括盖板102、防爆阀103和绝缘件101。防爆阀103设置在盖板102上，防爆阀103上还可覆盖有盖片。请参考图3和图4，绝缘件101包括正极侧的第一子绝缘件101A和负极侧的第二子绝缘件101B，第一子绝缘件101A和第二子绝缘件101B与盖板102连接。第一子绝缘件101A与正极耳302对应，第二子绝缘件101B与负极耳303对应，第一子绝缘件101A和第二子绝缘件101B沿盖板102的长度方向X对接。在一个实施例中，第一子绝缘件101A和第二子绝缘件101B可以是一体成型的，也可以是分体的。
本实施例提供一种绝缘件101，请参考图2和图3，具体为第二子绝缘件101B。第二子绝缘件101B包括主体板11、第一边条12A、凸台13、第一支撑条14A和第二支撑条14B。
主体板11在其厚度方向Z上包括相背的第一表面111和第二表面112。第一表面111和第二表面112为平面，其中主体板的第二表面112朝向盖板102。可选的，主体板11的方形的平板状，所以主体板11包括长度方向X、宽度方向Y和厚度方向Z。
优选的，主体板11的长度方向X可以为储能装置100的长度方向X，主体板11的宽度方向Y可以为储能装置100的宽度方向Y，主体板11的厚度方向Z可以为储能装置100的高度方向。
需要说明的，以下所涉及的长度方向X、宽度方向Y和厚度方向Z均以主体板11为参照。
第一边条12A连接在主体板11的长度方向X上的一端，且与主体板11之间具有间隔距离，第一边条12A相背的两端与主体板11为圆角连接。
可选的，绝缘件101还包括第二边条12B和第三边条12C。第二边条12B和第三边条12C均连接在主体板11的同一侧，且第二边条12B和第三边条12C在宽度方向Y上相对间隔设置，第一边条12A相背离的两端分别连接第二边条12B和第三边条12C。
进一步的，主体板11、第一边条12A、第二边条12B和第三边条12C共同围合容置口16。防爆阀103设置于容置口16。
优选的，第一边条12A和第二边条12B的连接处为圆角，第一边条12A和第三边条12C的连接处为圆角。请参考图6，第一边条12A、第二边条12B和第三边条12C满足关系式：0.8≤R1/R2≤1.2，1.8mm≤R1≤2.2mm，(mm：毫米millimeter)；其中，R1为第一边条12A和第二边条12B连接所形成的圆角的半径，R2为第一边条12A和第三边条12C连接所形成的圆角的半径。
通过设置第一边条12A相背的两端与主体板11为圆角连接的优势在于，能够减少储能装置100在安装时的有害摩擦，避免绝缘件101部分过于尖锐而磨破转接件20。
凸台13连接在主体板11的长度方向X上的一端，且位于主体板11和第一边条12A之间，凸台13凸出于第一表面111，凸台13的位置与防爆阀103对应，凸台13在主体板11的宽度方向Y上，包括相背第一外侧面131和第二外侧面132。
可选的，凸台13在宽度方向Y上相背离的两端分别连接第二边条12B和第三边条12C。所以凸台13位于主体板11和第一边条12A之间，且凸台13和容置口16的位置相对。
可选的，凸台13和防爆阀103之间具有间隔距离，方便气体在防爆阀103下方聚集，通过若干通气孔将气体导入防爆阀103。同时，凸台13隔开电芯301和防爆阀103，凸台13对防爆阀103起到了遮蔽作用，避免电池以外跌落时，电芯组件30直接撞击到防爆阀103而导致防爆阀103误触发。
第一支撑条14A和第二支撑条14B设置于主体板11和第一边条12A之间，第一支撑条14A和第二支撑条14B在主体板11的宽度方向Y上相对间隔设置，防爆阀103位于第一支撑条14A和第二支撑条14B之间。其中第一支撑条14A靠近第二边条12B，第二支撑条14B靠近第三边条12C。
可选的，第一支撑条14A和第二支撑条14B设置于容置口16，且第一支撑条14A和第二支撑条14B在长度方向X上相背的两端均分别连接主体板11和第一边条12A。第一支撑条14A和第二支撑条14B在厚度方向Z上的一端还可以与凸台13连接。
所以主体板11、第一边条12A、凸台13、第一支撑条14A和第二支撑条14B共同确定了容置空间17，防爆阀103设置在容置空间17中。
主体板11、第一边条12A、凸台13、第一支撑条14A和第二支撑条14B为一体成型结构，使得主体板11、第一边条12A、凸台13、第一支撑条14A和第二支撑条14B无需额外的连接结构，结构紧凑，连接可靠性高。
绝缘件101通过注塑工艺制作而成，注塑时通过模具(未图示)的注塑口向模具的模腔 中注入经高温熔化的热熔塑胶，热熔塑胶填满模腔后，待高温的热熔塑胶温度降低使得热熔塑胶凝固成型后，进行脱模，得到绝缘件101。其中，在注塑时，通过第一注塑部133注入热熔塑胶，一方面，从模具角度来看，第一注塑部133与模具的注塑口的位置对应，另一方面，从第二子绝缘件101B角度来看，第一注塑部133为绝缘件101外表面的某个位置。本申请实施例中，凸台13在第一外侧面131上具有第一注塑部133。
进一步的，可以在注塑时将第一注塑部133设置在上方，例如，设置模具以使主体板11的宽度方向Y在竖直方向上，第一外侧面131设置在主体板11背向地心的一侧，则塑胶流动时受到重力作用能够加快流动速度，进一步提高生产效率。
应当理解的是，当塑胶在模具内成型后，如塑胶稍微过量，则第一注塑部133会残留下凸起，如塑胶略有不足，则第一注塑部133会形成凹槽。对于残留有凸起的情况，脱模后，如剪切或打磨掉该凸起，则在最终产品上并不会留下该凸起，第一注塑部133会形成与其他部分齐平的平面结构。当然，在一些情况下，也可保留该凸起。对于本申请实施例而言，第一注塑部133为在凸台13第一外侧面131背向第二外侧面132的表面的预设区域的结构，该预设区域的结构可为凸起、凹槽或为平面。
本申请实施例中，设置第一注塑部133位于凸台13的第一外侧面131，使得熔化的塑胶液流动方向为主体板11的宽度方向Y，可以将注塑模具的脱模方向沿着主体板11的厚度方向Z设置，注塑口位于模具上方，塑胶液可以在重力作用下结合负压吸力双重引导，从上至下快速流动充满模腔；并且得益于塑胶液流动方向与凸台13和第一边条12A的延伸方向一致，从而避免凸台13和第一边条12A结构过长造成的塑胶液延不均匀的熔接痕现象；同时，结合上述中圆角连接的第一边条12A，使得在注塑时，塑胶液自上而下流经至第一边条12A的端部时，减少塑胶液以90度角撞击模具的内壁而形成涡流后产生的气泡，从而使得第一边条12A在弯角处的塑胶不会存在缺陷，提高第一边条12A在弯角处的结构强度。
一种实施方式中，请参考图3和图4，绝缘件101还包括沉台15，沉台15连接在主体板11远离凸台13的一端，沉台15凸出于第一表面111，沉台15包括背向第二外侧面132的第三外侧面151，第三外侧面151与第一外侧面131的朝向相同，在第三外侧面151上具有第二注塑部153。
可选的，沉台15在宽度方向Y上包括相背的第三外侧面151和第四外侧面152。其中，第三外侧面151与第一外侧面131的朝向相同，第四外侧面152与第二外侧面132的朝向相同。可以理解的，第二注塑部153的形状样式应该和第一注塑部133相同。
所以，在注塑时将第一注塑部133和第二注塑部153均设置在上方，例如，设置模具以使主体板11的宽度方向Y在竖直方向上，第一外侧面131和第三外侧面151设置在主体板11背向地心的一侧，则塑胶流动时受到重力作用能够加快流动速度，进一步提高生产效率。
可选的，沉台15和凸台13分别位于主体板11的长度方向X上的两端。由于沉台15凸出于第一表面111，使得沉台15可与下方的电芯组件30抵接，以使第一表面111与电芯组件30之间形成有间隙，以供第二转接件202、极耳等容置。沉台15背向凸台13的一侧用于与包覆电芯组件30的绝缘膜(通常为麦拉mylar)熔接固定，将电芯组件30兜住，提升储能装置100的抗振动效果。
通过在沉台15的与凸台13的同一侧设置第二注塑部153，使得绝缘件101在注塑成型时，可以利用第一注塑部133和第二注塑部153进行同时注液，一方面提高了绝缘件101的制造速度，并且位于主体板11两侧的注塑部中的塑胶液可以向主体板11的中间汇流，从而提高绝缘件101整体的均匀度；另一方面，塑胶液流动方向与沉台15的延伸方向一致，从而 避免沉台15结构过长造成的塑胶液延不均匀的熔接痕现象。
一种实施方式中，请参考图3，第一支撑条14A和第二支撑条14B为弧形，且第一支撑条14A朝背向第二支撑条14B的方向突出，第二支撑条14B朝背向第一支撑条14A的方向突出。
第一支撑条14A和第二支撑条14B可以为圆弧形结构。所以主体板11、第一支撑条14A、第二支撑条14B和第一边条12A可以共同围合一个轮廓为圆角矩形的容置空间17。
可选的，第一支撑条14A的弧度和第二支撑条14B的弧度可以相同。并且，设置弧度相同是为了能够契合防爆阀103的形状结构。
通过设置第一支撑条14A和第二支撑条14B均为弧形，一方面使得支撑条能够适配防爆阀103；另一方面，位于第一支撑条14A和第二支撑条14B之间的气流在二者的引导下，能够形成涡流状在防爆阀103的下侧汇聚，从而在储能装置100内部的气压增大时，呈涡流状汇聚的气流能够产生更大的气压，从而加快开阀速度。
一种实施方式中，请参考图5至图7，在主体板11的厚度方向Z上，第一支撑条14A和第二支撑条14B的一端连接凸台13，第一支撑条14A和第二支撑条14B的壁厚沿远离凸台13的方向逐渐减小。
可选的，请参考图5和图7，第一支撑条14A包括第一支撑部14A1和第二支撑部14A2，第二支撑部14A2相背离的两端分别连接第一支撑部14A1和凸台13；沿凸台13向第一支撑部14A1的方向，第二支撑部14A2的厚度逐渐减小。
优选的，第一支撑条14A和第二支撑条14B为镜像对称。需要解释的，对称面并非为绝缘件101上实际存在的面，而是为了说明第一支撑条14A和第二支撑条14B结构所设立的虚拟面，对称面位第一支撑条14A和第二支撑条14B之间，且对称面为主体板11的长度方向X和厚度方向Z所构成的面。所以，以下通过第一支撑条14A具体说明。
第一支撑条14A在主体板11的厚度方向Z上包括相连接的第一支撑部14A1和第二支撑部14A2，第二支撑部14A2位于第一支撑部14A1和凸台13之间。第一支撑部14A1相背离的两端分别连接主体板11和第一边条12A，第二支撑部14A2用于连接凸台13。
可选的，第二支撑部14A2呈现上窄下宽的结构。其中上方即为靠近第一支撑条14A的一端，下方即为靠近凸台13的一端。所以上述中第二支撑部14A2的厚度即为壁厚。
所以在第二支撑条14B和第一支撑条14A为镜像对称的情况下，第二支撑部14A2应该包括第三支撑部14B1和第四支撑部14B2，而且第四支撑部14B2应该也为上窄下宽的结构。
通过设置第二支撑部14A2的厚度逐渐减小，使得第二支撑部14A2和凸台13连接处的接触面更大，能够减小电芯301向上挤压时对应第二支撑部14A2位置的凸台13所受到的压强，从而避免凸台13差异化受力过大导致开裂并划伤极芯，提高绝缘件101的结构稳定性和结构强度；另一方面，注塑时第二支撑部14A2的位置对应为注塑用的流道，第二支撑部14A2壁厚较宽的位置可以便于更多的塑胶液快速通过且成型，避免第二支撑部14A2和凸台13的连接处缺胶或者形成熔接痕，以此提高生产良率和效率。
可选的，第一支撑部14A1和第二支撑部14A2均为圆弧形，且第三支撑部14B1和第四支撑部14B2也均为圆弧形。由于第一支撑条14A和第二支撑条14B均为圆弧形，而因为注塑冷却后圆弧形结构会出现收缩箍紧膜具凸块的现象。所以，设置第二支撑部14A2和第四支撑部14B2为上窄下宽的结构方便圆弧形筋脱膜，与模具凸块分离。
一种实施方式中，请参考图5，凸台13包括第一连接部13A和第二连接部13B。第一连接部13A和第二连接部13B在主体板11的宽度方向Y上相对间隔设置，第一连接部13A和 第二连接部13B凸出于第一表面111。
具体的，第一连接部13A连接第二边条12B，第二连接部13B连接第三边条12C。需要解释的，因为第二边条12B和第三边条12C均连接主体板11，且边条的厚度可以和主体板11的厚度相同。所以第一连接部13A和第二连接部13B凸出于第一表面111，即为第一连接部13A凸出于第二边条12B的表面，第二连接部13B凸出于第三边条12C。
可选的，凸台13还包括与主体板11平行的透气板13C，透气板13C相背的两端分别连接第一连接部13A和第二连接部13B，透气板13C包括朝向第一表面111的第三表面，第一支撑条14A和第二支撑条14B连接在第三表面上。
透气板13C可以为长方形板状结构，其在主体板11宽度方向Y上的两端分别连接第一连接部13A和第二连接部13B。透气板13C上可以开设有透气孔13C3，壳体40内的气体通过透气孔13C3流向容置空间17内。
可选的，透气板13C背向电芯组件30的一面为第三表面。上述中的第二支撑部14A2和第四支撑部14B2均连接在第三表面上。即第二支撑部14A2和第四支撑部14B2壁厚较厚的一边连接在透气板13C上。
通过设置第一连接部13A和第二连接部13B连接在透气板13C相对的两端，并设置第一连接部13A和第二连接部13B为突出第一表面111的结构，使得透气板13C所在的平面相较于低于主体板11所在的平面，从而为容置防爆阀103、第一限位条和第二限位条提供的空间；进一步的，第一连接条和第二连接条连接在透气板13C的第三表面上，可以提高透气板13C在和主体板11之间的结构强度，提高透气板13C的抗压能力。
一种实施方式中，请参考图4和图5，所述第一外侧面131位于所述第一连接部13A，所述第二外侧面132位于所述第二连接部13B，所述第一外侧面131和所述第二外侧面132的形状均为正梯形，所述第一外侧面131和所述第二外侧面132连接所述主体板11的一边为长顶边，连接所述透气板13C的一边为短顶边。
第一外侧面131为第一连接部13A背向第二连接部13B的一面，第二外侧面132为第二连接部13B背向第一连接部13A的一面。
可选的，第一连接部13A和第二连接部13B在主体板11长度方向X上的尺寸可以为上宽下窄的结构。其中，上方为连接边条的一端，下方为连接透气板13C的一端。
优选的，第一连接部13A和第二连接部13B均为正梯形结构。其中第一连接部13A连接第二边条12B的一端为长顶边，连接透气板13C的一端为短顶边；第二连接部13B连接第三边条12C的一端为长顶边，连接透气板13C的一端为短顶边。
通过设置第一连接部13A和第二连接为梯形截面的结构，有利于在制造时利用一对梯形动模具和梯形定模具配合注塑，且在梯形模具无需高精度操作对准便可完成互相快速卡合，并且密封性较强，能够避免溢胶，进一步提升产品生产效率和良率；同时，由于连接主体板11的一侧为长顶边，能够加强第一连接部13A和第二连接与主体板11之间的连接强度，从而提高绝缘件101整体的结构稳固性。
一种实施方式中，请参考图6，所述透气板13C在所述主体板11的长度方向X上还包括相背离的第一边缘13C1和第二边缘13C2，所述第一边缘13C1与所述主体板11之间具有间隔距离，所述第二边缘13C2与所述第一边条12A之间具有间隔距离。
具体的，在主体板11的长度方向X上，透气板13C相背的两侧分别为第一边缘13C1和第二边缘13C2。其中，第一边缘13C1为透气板13C靠近主体板11的一端，第二边缘13C2为透气板13C靠近第一边条12A的一端。所以，第一边缘13C1与主体板11之间具有间隔距 离，第二边缘13C2与第一边条12A具有间隔距离，可以理解为，第一边缘13C1和第二边缘13C2分别与主体板11和第一边条12A为不连接的状态。
可选的，第一边缘13C1和第二边缘13C2可以分别和主体板11和第一边条12A在厚度方向Z上具有间隔距离。举例而言，透气板13C的长度(在主体板11的长度方向X上的尺寸，下文同理)可以大于或等于容置口16的口径(在主体板11的长度方向X上的口径，下文同理)；所以透气板13C和主体板11以及第一边条12A之间仅存在高度差。
所以在上述方案中，第一边缘13C1和主体板11之间的间隔距离可以为第一气流槽Q1，第二边缘13C2和第一边条12A之间的间隔距离可以为第二气流槽Q2。
通过设置主体板11的第一边缘13C1与主体板11之间具有间隔距离，第二边缘13C2与第一边条12A之间具有间隔，提高了气流流至防爆阀103处的气体通道数量，从而使得储能装置100内的气体可以快速的在防爆阀103的附近流动，以此在储能装置100内部产气后，气体能够顺利的抵达防爆阀103处从而将防爆阀103冲破。
一种实施方式中，请参考图6，在主体板11的长度方向X上，第一边缘13C1到第二边缘13C2的距离小于主体板11到第一边条12A的距离。
具体的，在上述实施方式的基础上，透气板13C和容置口16为相对设置的。所以，第一边缘13C1到第二边缘13C2的距离即为透气板13C在长度方向X上的长度，主体板11到第一边条12A的距离即为容置口16在长度方向X上的口径。
所以透气板13C和主体板11以及第一边条12A之间不仅存在高度差，还在长度方向X上具有长度差。以此使得上述中的第一气流槽Q1和第二气流槽Q2能够具有更大的开口尺寸，从而在单位时间内第一气流槽Q1和第二气流槽Q2能够流过更大的气流。
通过设置第一边缘13C1到第二边缘13C2的距离小于主体板11到第一边条12A的距离，使得第一边缘13C1和主体板11之间的距离，以及第二边缘13C2和第一边条12A之间的距离更大，从而形成更大的气流槽，在电芯301产气后，气体能够通过所形成的气流槽快速汇聚到防爆阀103的下端，从而实现快速相应的目的。
一种实施方式中，请参考图8，主体板11、透气板13C和第一边条12A满足关系式：0.85≤S1/S2≤1.15，其中，S1为第一边缘13C1到主体板11的最小距离，S2为第二边缘13C2到第一边条12A的最小距离。
需要解释的，第一边缘13C1到主体板11的最小距离，应该为第一边缘13C1到主体板11朝向第一边条12A一侧的直线距离；第二边缘13C2到第一边条12A的最小距离，应该为第二边缘13C2到第一边条12A朝向主体板11一侧的直线距离。具体可参照图8中所标注处的S1和S2。
所以S1和S2可以理解为第一气流槽Q1和第二气流槽Q2的槽宽。而将S1和S2之间的比值设定在上述外围内，可以确保所形成的第一气流槽Q1和第二气流槽Q2的槽宽相近，以此使得防爆阀103两侧的气流相近。该设计可以防止经过第一气流槽Q1和第二气流槽Q2的气体由于流量不均而产生的气压差，在搬运储能装置100的过程种，或受外力冲击的情况中，能够避免产生气压差而导致的误开防爆阀103的现象。
可选的，S1/S2的具体大小可以但不限于为0.85、0.9、0.95、1、1.05、1.1、1.15。当S1和S2的比值超过上述范围时，说明两侧的口径不同，会出现第一气流槽Q1的气流大于第二气流槽Q2的气流(或第二气流槽Q2的气流大于第一气流槽Q1的气流)的情况，从而产生气压差或紊流现象，容易造成防爆阀103误开的情况。
一种实施方式中，在主体板11的长度方向X上，第二支撑部14A2的直线长度小于等于 透气板13C的长度，且第四支撑部14B2的直线长度小于等于透气板13C的长度。
具体的，在上述实施方式的基础上，第二支撑部14A2在主体板11的长度方向X上的直线长度，应该为第二支撑部14A2在长度方向X上背离的最远两端的直线距离。
可选的，第一支撑部14A1和第二边条12B在宽度方向Y上应该为正对设置的，第二支撑部14A2和第一连接部13A在宽度方向Y上应该为正对设置的。所以，当第二支撑部14A2的直线长度小于等于透气板13C的长度时，第一连接部13A在第二连接部13B上的正投影应该完全覆盖第二支撑部14A2在第二连接部13B上的正投影的。
可选的，第一支撑条14A和第一连接部13A之间具有间隔距离，第二支撑条14B和第二连接部13B之间具有间隔距离。
通过设置第二支撑部14A2的直线长度小于等于透气板13C的长度，使得上述中的第一气流槽Q1和第二气流槽Q2在宽度方向Y上没有阻挡，气体能够在第一气流槽Q1和第二气流槽Q2中实现纵向流动；并且由于第一支撑条14A和第一连接部13A之间具有间隔距离，使得第一气流槽Q1和第二气流槽Q2能够通过第一支撑条14A和第一连接部13A之间的间距连通，在第一支撑条14A和第二支撑条14B均为环形的情况下，能够在防爆阀103的外周形成类圆环型的气流通道(请参考图6中的环形虚线，以下简称环形气道)。
进一步的，该环形气道的优势在于，在储能装置100为常压状态下，环形气道更有利于气体循环；而在增压情况下，环形气道更有利于气体形成涡流然后向防爆阀103形成汇流。
一种实施方式中，请参考图6，透气板13C上设有多个透气孔13C3，多个透气孔13C3呈多行多列排布。具体的，透气板13C上的透气孔13C3均可以为圆形，且尺寸相同。举例而言，透气板13C上的透气孔13C3的数量可以为十八个；且十八个透气孔13C3可以为两列九行排布。
通过在透气板13C上开设多个透气孔13C3，有利于增加防爆阀103处的气体流量，从而提高防爆阀103的响应速度。
一种实施方式中，请参考图6，多个透气孔13C3分为第一透气孔组N、第二透气孔组M和第三透气孔组W(请参考图6中的方形虚线)，第一透气孔组N、第二透气孔组M和第三透气孔组W沿主体板11的宽度方向Y依次排布，第一透气孔组N和第三透气孔组W中的透气孔13C3数量相同，第一透气孔组N中的透气孔13C3数量小于第二透气孔组M中的透气孔13C3数量，第二透气孔组M与防爆阀103对应。
具体的，第一透气孔组N和第二透气孔组M中的透气孔13C3数量均可以为四个。第一透气孔组N靠近第一连接部13A，第三透气孔组W靠近第二连接部13B。所以第二透气孔组M中的透气孔13C3数量为十个，且十个透气孔13C3均与容置空间17连通，且与防爆阀103对应设置。
通过划分多个透气孔13C3为第一透气孔组N、第二透气孔组M和第三透气孔组W，且设置具有较多透气孔13C3的第二透气孔组M与防爆阀103对应，使得防爆阀103和透气板13C之间的气体能够快速汇聚；并且，第一透气孔组N和第三透气孔组W的透气孔13C3数量相同，使得汇流至环形气道的气体为均匀的，不会产生气压差而导致破坏环形气道的情况。
一种实施方式中，请参考图6，第一支撑条14A与透气板13C的连接点位于第一透气孔组N和第二透气孔组M之间，第二支撑条14B与透气板13C的连接点位于第二透气孔组M和第三透气孔组W之间。
通过设置第二透气孔组M位于第一支撑条14A和第二支撑条14B之间，使得经第二透气孔组M流至防爆阀103下侧的气流不会在短时间内流出，从而能够提高气体的汇聚效率， 从而进一步提高防爆阀103的响应速度。
