Description

储能装置的防水组件与储能装置
本申请要求于2021年11月25日提交的名称为“储能装置的防水组件与储能装置”的中国专利申请202122918062.9的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及储能技术领域，具体涉及一种储能装置的防水组件和储能装置。
 背景技术
由于市场对清洁能源的广泛需求，储能装置得到了广泛应用。但由于风能、光伏发电、潮汐能等清洁能源的生产设备多在野外，储能装置也通常露天放置。在下雨天气时，雨水容易进入储能装置内部，轻者破坏储能装置的功能，重者造成漏电等危险事故的发生。因此，如何增强储能装置的防雨淋能力成为亟待解决的一项问题。
 技术问题
鉴于防雨淋能力问题，本申请实施例提供了一种储能装置的防水组件和储能装置，能够提高储能装置的防雨淋能力。
 技术解决方案
鉴于上述问题，本申请实施例提供了一种储能装置的防水组件和储能装置，能够提高储能装置的防雨淋能力。
本申请第一方面提供一种储能装置的防水组件，包括凸台和线束罩。凸台设置于电池的箱体外壁，凸台包括第一外突部，第一外突部围成第一通孔，第一通孔与箱体内部连通。线束罩设置为中空腔体结构以收纳线束，线束罩内部包括第一凹槽，第一凹槽用于容纳第一外突部以使第一通孔与中空腔体相连通。
在本申请一实施例中，第一外突部与第一凹槽在凸台的轴向上过盈配合。过盈配合连接的结构简单，对第一外突部与第一凹槽的强度削弱小，耐冲击性好。由于第一外突部的外侧壁与第一凹槽的内壁过盈配合，从而使线束罩对凸台的密封性能得到极大地提高。
在本申请一实施例中，凸台包括第一端和第二端。第一端与箱体的侧壁相连接。第二端与第一端相对设置，第二端设置有第一外突部。其中，第一端与第一外突部之间形成第二凹槽，第二凹槽用于在第一凹槽容纳第一外突部时容纳线束罩的一部分。本方案可以增强线束罩对凸台的密封性能。
在本申请一实施例中，线束罩包括口部、尾部和过度部。口部位于线束罩用于与凸台相连接的一端，口部设置有开口，第一外突部经开口进入线束罩的中空腔体。尾部位于线束罩的另一端，尾部包括第二通孔，线束经第二通孔进入线束罩的中空腔体内。过度部连接口部和尾部，过度部连接于口部一端的外径大于过度部连接于尾部一端的外径。本方案可以减少尾部的体积，从而减少线束罩在储能装置中的占用体积，进而提高储能装置的能量密度。
在本申请一实施例中，口部包括开口段和连接段。开口段位于口部与凸台相连接的一端。连接段位于口部的另一端，用于连接开口段和过度部。其中，连接段的内径大于开口段的内径，开口段和连接段和过度部共同形成第一凹槽。
在本申请一实施例中，凸台还包括第二外突部。第二外突部位于第二凹槽中，第二外突部与第一外突部形成第三凹槽，第三凹槽用于在第一凹槽容纳第一外突部时容纳开口段的至少部分，开口段的至少部分与第三凹槽过盈配合。本方案可以进一步增强线束罩对凸台的密封性能。
在本申请一实施例中，开口段与第二外突部相接触的部分设有朝向第一端延伸的第三外突部。第二外突部设有与第三外突部相匹配的第四凹槽。本方案可以进一步增强线束罩对凸台的密封性能。
在本申请一实施例中，尾部包括折弯尾管。折弯尾管的内腔与第二通孔相连通。本方案可以增强线束罩的防雨淋能力。
在本申请一实施例中，线束罩的材质包括橡胶。本方案可以增强线束罩的密封性能。
本申请第二方面提供一种储能装置，包括电池、线束和本申请第一方面提供的任一项防水组件。防水组件用于实现线束与电池连接处的防水功能。本申请第二方面提供的储能装置具有防雨淋效果优良的特点。

以下实施例为了方便说明，以本申请一实施例的一种储能装置1000为例进行说明。
请参看图1，图1为本申请一些实施例提供的储能装置1000的结构示意图。储能装置1000的内部设置有电池100和柜架200，电池100可以设置在柜架200上。多个电池100可以在柜架200之间自上而下堆叠设置。
请参看图2，图2为本申请一些实施例提供的电池100的爆炸图。电池100包括箱体10和电池单体20，电池单体20容纳于箱体10内。其中，箱体10用于为电池单体20提供容纳空间，箱体10可以采用多种结构。在一些实施例中，箱体10可以包括第一部分11和第二部分12，第一部分11与第二部分12相互盖合，第一部分11和第二部分12共同限定出用于容纳电池单体20的容纳空间。第二部分12可以为一端开口的空心结构，第一部分11可以为板状结构，第一部分11盖合于第二部分12的开口侧，以使第一部分11与第二部分12共同限定出容纳空间；第一部分11和第二部分12也可以是均为一侧开口的空心结构，第一部分11的开口侧盖合于第二部分12的开口侧。当然，第一部分11和第二部分12形成的箱体10可以是多种形状，比如，圆柱体、长方体等。

请参看图4和图5，图4为本申请一些实施例的一种储能装置1000的局部示意图，图5为图4中A区域的放大图。如图4所示，多个电池100在多个柜架200所组成的空间中堆叠放置，多个电池100之间通过线束300实现电连接。如图5所示，线束罩30设置于电池的箱体10上，线束300穿过线束罩30与箱体10内部的电池100实现电连接。
请参看图6至图8，图6为本申请一些实施例的一种防水组件的爆炸图，图7为本申请一些实施例中单个线束罩30与电池箱体10的连接示意图，图8为图7中C区域沿B-B方向的剖面结构示意图。根据本申请的一些实施例，本申请提供了一种储能装置1000的防水组件，防水组件包括凸台40和线束罩30。凸台40设置于电池的箱体10外壁，凸台40包括第一外突部41，第一外突部41围成第一通孔401，第一通孔401与箱体10内部连通。线束罩30设置为中空腔体结构以收纳线束300，线束罩30内部包括第一凹槽301，第一凹槽301用于容纳第一外突部41以使第一通孔401与中空腔体相连通。
凸台40设置于箱体10外壁，用于与线束罩30连接。凸台40的材质可以为铁、镁、铝等金属材料，也可以为PBT（Polybutylece Terephthalate，聚对苯二甲酸丁二酯）等工程塑料。凸台40的内部可以为中空管道结构，以便于线束300通过凸台40的中空管道与电池100电连接。凸台40的外部可以为长方体或圆柱体、球体等简单几何结构，也可以为长方体或圆柱体、球体等简单几何结构组合而成的复杂几何结构。
凸台40包括有第一外突部41，第一外突部41可以设置在凸台40与箱体10侧壁相对的一端，并沿凸台40的径向X朝箱体10的棱的方向延伸。
第一外突部41向凸台40的四周延伸，并在内部围成有第一通孔401。第一通孔401可以与箱体40的内部连通，以便于线束300穿过第一通孔401与电池100电连接。

通过在箱体10上设置具有第一外突部的41凸台40，并在线束罩30内设置可以容纳第一外突部41的第一凹槽301。由此，线束罩30可以将与凸台41相连接的部位包裹在罩内，防止雨水直接淋入线束罩30或箱体10内，从而增强储能装置1000的防水能力。
根据本申请的一些实施例，可选地，第一外突部41与第一凹槽301在凸台41的轴向Y上过盈配合。
第一外突部41与第一凹槽301在凸台41的轴向Y上过盈配合，即第一外突部41的轴向的外侧壁的直径D1大于第一凹槽301的内侧壁的直径D2。过盈配合是指在机械安装过程中，有零件间需要紧密配合时，利用材料的弹性使第一凹槽301扩大，变形而套在第一外突部41上，当第一凹槽301复原时产生对第一外突部41的箍紧力，从而使第一外突部41与第一凹槽301紧密配合。
过盈配合连接的结构简单，对第一外突部41与第一凹槽301的强度削弱小，耐冲击性好。由于第一外突部41的外侧壁与第一凹槽301的内壁过盈配合，从而使线束罩30对凸台40的密封性能极大地提高了。
请参看图9和图10，图9为本申请一些实施例的一种凸台40的结构示意图，图10为图9所示凸台40在X-Y平面上的剖面结构示意图。根据本申请的一些实施例，可选地，凸台40包括第一端40a和第二端40b。第一端40a与箱体10的侧壁相连接。第二端40b与第一端40a相对设置，第二端40b设置有第一外突部41。其中，第一端40a与第一外突部41之间形成第二凹槽402，第二凹槽402用于容纳线束罩30的一部分。
在第一凹槽301容纳第一外突部41时，通过在凸台40上设置第二凹槽402以容纳线束罩30的一部分，可以增强线束罩30对凸台40的密封性能。
请参看图11至图14，其中，图11为本申请一些实施例的一种线束罩30的结构示意图，图12为图11的线束罩30的正视图，图13为图11的线束罩30的俯视视角下的剖面结构示意图，图14为图11的线束罩30的沿D-D方向的剖面结构示意图。根据本申请的一些实施例，可选地，线束罩30包括口部31、过度部32和尾部33。口部31位于线束罩30用于与凸台40相连接的一端，口部31设置有开口310，第一外突部41经开口310进入线束罩30的中空腔体。尾部33位于线束罩30的另一端，尾部33包括第二通孔302，线束300经第二通孔302进入线束罩30的中空腔体内。过度部32连接口部31和尾部33，过度部32连接于口部31一端的外径D3大于过度部32连接于尾部33一端的外径D4。
口部31位于线束罩30与凸台40相连接的一端，用于与凸台40相连接。口部31可以设置开口310，第一外突部41经开口310进入线束罩30的中空腔体内并被第一凹槽301以容纳。口部31的材质可以为PBT等工程塑料或橡胶等具有弹性的材料。
尾部33位于线束罩30的与口部31相对的另一端。尾部33可以包括第二通孔302，线束300可以经第二通孔302进入线束罩30的中空腔体，并进而通过口部31进入第一通孔401与电池100相连接。
过度部32用于连接口部31和尾部33。如图13所示，过度部32连接于口部31一端的外径D3可以大于过度部32连接于尾部33一端的外径D4。
将线束罩30设置为尾部33的外径D4小于口部31的外径D3可以减少尾部33的体积，从而减少线束罩30在储能装置1000中的占用体积，进而提高储能装置1000的能量密度。
请参看图13至图14，根据本申请的一些实施例，可选地，口部31包括开口段311和连接段312。开口段311位于口部31与凸台40相连接的一端。连接段32位于口部31的另一端，用于连接开口段311和过度部32。其中，连接段312的内径D5大于开口段311的内径D6，开口段311和连接段312和过度部32共同形成第一凹槽301。
请参看图15，图15为本申请一些实施例的一种线束罩30和凸台40的部分结构剖面示意图。根据本申请的一些实施例，可选地，凸台40还包括第二外突部42，第二外突部42位于第二凹槽402中，第二外突部42与第一外突部41形成第三凹槽403，第三凹槽403用于在第一凹槽301容纳第一外突部41时容纳开口段311的至少部分，开口段311的至少部分与第三凹槽403过盈配合。
在凸台40上增设第三凹槽403，并使开口段311的至少部分与第三凹槽403过盈配合，可以增强线束罩30对凸台40的密封性能。
请参看图16，图16为本申请一些实施例的另一种线束罩30和凸台40的部分结构剖面示意图。根据本申请的一些实施例，可选地，开口段311与第二外突部42相接触的部分设有朝向第一端40a延伸的第三外突部313，第二外突部42设有与第三外突部313形状相匹配的第四凹槽404。
在凸台40上增设第四凹槽404，以及在线束罩30上设置与第四凹槽404相配和的第三外突部313，可以增强线束罩30对凸台40的密封性能。
请参看图17，图17为本申请一些实施例的一种包含折弯尾管331的线束罩30的结构示意图。根据本申请的一些实施例，可选地，尾部33包括折弯尾管331，折弯尾管331的内腔与第二通孔302相连通。
