目前,随着新能源的大力发展,新能源动力电池的使用越来越多。新能源电池具有性价比高、安全性好、低污染等优点的突显,已经取得越来越广泛的应用,不仅仅应用在普通电子领域,还逐渐在动力和储能领域得到应用。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统,而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具,以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大,其市场的需求量也在不断地扩增。动力电池作为新能源用电装置的核心部件,其安全性直接影响到用电装置的安全性能。
储电柜,是一种将一个或多个电池包箱体(下文简称电箱)放置在柜体内而形成的能量高度集中的储能装置。由于柜体内部电箱电压高,当电箱发生热失控时,会产生大量的高温高压气体,该高温高压气体会聚积到储电柜的柜体中,进而引起爆炸。对此,储电柜内往往充满氮气,以用于减少柜内电箱热失控引发消防安全隐患问题。
储电柜结构由柜体和门扇组成,相关技术往往只考虑柜体和门扇的连接方式,未考虑详细的密封的方案,尤其对于大型储电柜,柜体与门扇设计的配合间隙很难控制到预期范围,储电柜柜体与门扇之间的安装气密性往往难以得到保障。由于储电柜气密性较差,导致柜体内部的氮气大量泄漏至柜体外部,并且柜体外部环境中的空气流进储电柜内部。在电箱热失控情况下,柜体内部由于氮气的减少,以及新增混入的外部空气,导致电箱容易起火及发生安全事故。此外,由于储电柜密封性差,柜体内高温高压气体容易往外扩散,柜内火势往柜外蔓延,导致储电柜加重用电装置的安全隐患的现象。因此,用电装置的安全性能对储电柜的气密性提出了严格要求。
为了提高用电装置整体安全性,一些相关技术中,在储电柜柜体棱边的满焊工艺中,采用塔边拼焊方法,其柜体与门扇之间的配合间隙减小,结构强度能够得到很大提高,但是,由于焊缝很多及钢板很薄等原因,提高柜体气密性的加工难度很大,柜体仍然无法气密,产品一致性不高。一些相关技术还额外采 用配套的密封设备及检验设备以减小柜体与门扇之间的间隙,该类技术增加了大型储电柜加工技术难度和加工成本,实际适用性较差。对大型储电柜,由于柜体较大,相关技术往往较难做到良好的气密,消防安全隐患较大,一些相关技术中,大型储电柜采用柜体内壁粘贴防火棉的方式实现消防安全问题,但是单个电芯起火会引发柜内所有电芯燃烧甚至发生爆炸,无法从根源上解决储电柜起火及爆炸问题。相关技术中,储电柜密封性难以达到预期效果。
为解决上述问题,本申请实施例设计一种储电柜,该储电柜通过将门扇外框和柜门外框密封连接,降低了起火及爆炸的概率,从根源上提高了消防安全可靠性。相比于传统储电柜结构,本申请实施例实现了储电柜的气密装配,从而起到从根源上提高储电柜的消防安全可靠性和使用寿命的作用。
当然,尤其需重点说明的是,本申请的柜体密封技术包括但不限于用于储电柜,还可以用于柜内为高温高压环境的其余柜体装置,例如,还可以用于配电柜、汇流柜等。
本申请实施例提供了一种使用储电柜作为电源的储能装置,该储能装置可以为但不限于电动玩具、电动工具、电瓶车、电动汽车、轮船、航天器等等。其中,电动玩具可以包括固定式或移动式的电动玩具,例如,游戏机、电动汽车玩具、电动轮船玩具和电动飞机玩具等等,航天器可以包括飞机、火箭、航天飞机和宇宙飞船等等。
本申请实施例中,储电柜可以包括但不限于为具有容纳空间的柜体式储能装置,该容纳空间内可以放置一个或多个电箱(全称电池包箱体),其中,电箱用于为储电柜提供电能。本申请实施例中,电箱由至少一个电池包组成。
以下对本申请实施例的相关概念做进一步解释。
电芯(Cell):指单个含有正、负极的电化学电池的最小功能单元,一般不直接使用,区别于电池含有保护电路和外壳,可以直接使用,其必须要有较高的能量密度,以及尽可能多的存储电能。除此之外,电芯的寿命也是最为关键的因素,任何一颗电芯的损坏,都会导致整个电池包的损坏。
电池模组(Module):当多个电芯被同一个外壳框架封装在一起,通过统一的边界与外部进行联系时,这就组成了一个模组。
电池包(Pack):当数个模组被电池管理系统(BMS)和热管理系统共同控制或管理起来后,这个统一的整体就叫做电池包。
电芯、模组和电池包的区别,除了电池数量以外,还有是否有附加的管理系统的区别。
请参阅图1,第一方面,本申请实施例提供一种储能装置1000,包括储电柜100。
本申请实施例的储能装置1000,具备良好的气密效果,提高了储能装置1000的消防安全性能。
在一些实施例中,该储能装置1000还包括控制器、消防介质源、冷却介质源等,分别通过穿线孔和进出口连接储电柜100。
请参阅图2-图5,本申请实施例提供了一种储电柜100,包括:包括柜体1和门扇2,柜体1具有柜门外框101,门扇2具有门扇外框201,柜门外框101与门扇外框201密封接触;柜门外框101具有沿柜门外框101的周向设置的第一连接部10101,门扇外框201具有沿门扇外框201的周向设置的第一配合部20101,第一连接部10101与第一配合部20101线面密封。
值得说明的是,本申请实施例的技术方案中,柜门外框101与门扇外框201密封接触可以通过多种方式实现。
例如,在一些实施例中,在柜门外框101与门扇外框201之间的接触面上设置独立的密封件,密封件夹设于柜门外框101与门扇外框201之间的缝隙处,柜门外框101和/或门扇外框201朝指向其中另一者的方向挤压密封件,从而实现柜门外框101与门扇外框201的气密装配。其中,独立的密封件指密封件与柜门外框101、门扇外框201之间可分离。
示例性的,密封件可以包括但不限于为套设于柜门外框101或门扇外框201上的橡胶条、橡胶圈、弹性衬垫等。
又如,在一些实施例中,基于柜门外框101的本体和门扇外框201的本体,分别一体设置的相配合使用的密封结构,柜门外框101的密封结构与柜门外框101为一体式结构,门扇外框201的密封结构与门扇外框201为一体式结构。柜门外框101的密封结构与门扇外框201的密封结构适配安装、相互挤压,挤压安装后的密封结构填补柜门外框101与门扇外框201之间的缝隙,从而实现柜门外框101与门扇外框201的气密装配。
示例性的,密封结构可以包括但不限于为:设于柜门外框101或门扇外框201上、并且朝向其中另一者凸起的弹性凸起结构件,以及设于柜门外框101与门扇外框201的另一者上的密封槽,弹性凸起结构件与密封槽对应设置,弹性凸起结构件伸入密封槽内,利用弹性凸起结构件的弹性变形量,起到补偿柜门外框101与门扇外框201之间的缝隙的效果。
其中,沿柜门外框101或门扇外框201的周向,弹性凸起结构呈连续状结构或间断结构。示例性的,弹性凸起结构件可以包括但不限于为:一体凸设于门扇外框201或柜门外框101上的弹性凸条、弹性凸点、弹性卡扣等结构。密封槽可以包括但不限于:为凹设于门扇外框201或柜门外框101上的连续式环状沟槽结构,该连续式环状沟槽结构容纳至少一个弹性凸起结构件;或,为凹设于门扇外框201或柜门外框101上的间断式开孔结构,该间断式开孔结构与弹性凸起结构件一一对应设置。其中,弹性凸起结构件与密封槽的数量可以为一对多、多对一、多对多或一对一。借助弹性凸起结构件与密封槽的配合安装、相互挤压,以填补柜门外框101与门扇外框201之间的缝隙,从而实现柜门外框101与门扇外框201的气密装配。
本申请实施例的技术方案中,可以通过设计密封件和/或密封结构受挤压的相对变形量大于柜门外框101的相对变形量,利用密封件和/或密封结构的弹性变形,抵消储电柜100柜门外框101的加工变形量、使用变形量,以填补配合接触面之间的间隙,从而利用密封件和/或密封结构提高储电柜100的密封性能。通过柜门外框101与门扇外框201密封接触,实现柜体1与门扇2的气密装配。
由于柜门外框101与门扇外框201之间密封装配,使得柜体1内部的氮气难以泄漏至柜体1外部环境,柜体1外部环境中的空气难以流进储电柜100的内部,从而即便在储电柜100的内部发生电池热失控情况下,柜体1内部仍然可以保持足量的氮气,且隔离了氧气,柜内惰性环境得以保障,大大减少储电柜100内部起火的概率,提高了储电柜100的安全性能。此外,由于本实施例储电柜100具有良好的气密性,柜体1内部聚集的高温高压气体难以逃窜至柜外,大大减少了储电柜100用电装置安全事故的发生。
一些实施例中,为进一步提高柜体1与门扇2的气密性,在柜体1和门扇2的左下角、左上角、右下角、右下角设计过渡圆角,以减少在储能柜的各转角位置处柜体1与门扇2的摩擦损耗,从而提高储电柜100气密效果的持久性。
一些实施例中,柜体1还设有穿线孔,穿线孔内安装有与柜体1连接的其余密封件,以提高柜体1的气密性。
相比于传统储电柜,本申请实施例储电柜100通过将门扇外框201和柜门外框101密封连接,实现了储电柜100的气密装配,降低了起火及爆炸的概率,从根源上提高了消防安全可靠性和使用寿命的作用。此外,电池置于密封装配的储电柜100内,可用于在潮湿,积水,腐蚀严重的各种场景下,通过气密装配的柜体1,减少柜内电池受到损害腐蚀损坏。
本申请实施例的技术方案中,柜门外框101的周向指柜门外框101的四周。即,柜门外框101具有沿柜门外框101的周向设置的第一连接部10101,指柜门外框101的四周,设置第一连接部10101。门扇外框201的周向指门扇外框201的四周。即,门扇外框201具有沿门扇外框201的周向设置的第一配合部20101,指绕门扇外框201的四周,设置第一配合部20101。下文中的柜门外框101的周向、门扇外框201的周向,也可采用相同的解释。
值得说明的是,本申请实施例的技术方案中,第一连接部10101与第一配合部20101密封配合形成第一密封单元。其中,第一连接部10101和第一配合部20101指用于实现柜门外框101与门扇外框201之间的装配的,并且在装配状态下,柜门外框101与门扇外框201之间相交接的位置处的接触部。
本申请实施例提及的线面密封,指相接触的两个物体,其中一者与对方相配合安装的接触部的端面结构为面状体结构,另一者与对方相配合安装的接触部的端面结构为线状体和/或点状体等非面状结构,在面状结构体与非面状结构体相交接的接触部位置处,该非面状体结构装配入该面状体结构内,使得第一连接部10101和第一配合部20101之间的接触部完全接触,从而实现两物体的线面接触式气密装配。一些实施例中,设计第一连接部10101的横截面为前述非面状结构,设计第二连接部10102的横截面为面状结构。
示例性的,如图3所示,第一连接部10101的端面和第一配合部20101的端面,垂直或大致垂直于第一连接部10101与第一配合部20101的接触部所在平面;其中,第一连接部10101的端面为点状,第一配合部20101的端面为平面状,第一连接部10101与第一配合部20101的连接为线面接触,且气密装配,从而实现柜门外框101与门扇外框201的线面密封。
为实现门扇外框201与柜门外框101的气密装配,非面状结构和面状结构中至少一者由可变形弹性材 料制成。
由于生产加工原因或长时间使用原因,在沿周向方向,储电柜100的柜门和门扇2可能存在多处表面平整度不一致的凹凸不平之处,导致柜门与门扇2之间的各间隙大小不一致。对此,本申请实施例利用线面密封技术,通过接触部处的非面状结构装配入面状结构内,以填充该处柜门与门扇2之间的间隙,并且,利用各接触部处的弹性变形量,以灵活适配大小不一致的相应间隙,从而可以使得柜体1与门扇2之间的间隙被有效填充,以提高柜体1与门扇2之间的气密装配效果。
其中,由于柜门与门扇2之间的各间隙,可能沿柜门的周向方向或门扇2的周向方向零散分布,因此,为使全部间隙被完全填充,第一连接部10101可以是多个散布于柜门外框101的周向方向的密封结构,第二连接部10102可以是多个散布于门扇外框201的周向方向的密封结构;第一连接部10101还可以是沿柜门外框101的周向方向设置的非间断式密封结构,第二连接部10102也可以是沿柜门外框101的周向方向设置的非间断式密封结构。
例如,非面状结构可以为弹性凸条或非弹性凸条等非间断式结构,也可以为弹性凸点或非弹性凸点等间断式结构,面状结构还可以为弹性密封平面、非弹性密封平面等,其中,通过将凸条或凸点装配入密封平面内,从而实现线面密封。
根据本申请的一些实施例,第一连接部10101与第一配合部20101之一为第一密封凸条,第一连接部10101与第一配合部20101之另一为第一密封面。
本实施例的技术方案中,通过将非面状结构设计为凸条结构,将面状结构设计为平面结构,其中,通过将密封凸条装配入密封平面内,第一密封凸条与第一密封面密封接触以实现线面密封。由于密封凸条为非间断式一体结构,使得柜门与门扇2之间的密封结构不易掉落,提高了线面密封的密封稳定性。
示例性的,非面状结构可以为一种橡胶圈,该橡胶圈在接触部处的横截面具有一个或多个棱角、棱边、顶角、或顶边等线性凸起部,线性凸起部朝向面状结构的方向突出设置;面状结构可以为另一种橡胶圈,该橡胶圈在接触部处的横截面形状为具有一个或多个平面或内凹的弧形面,该弧形面朝指向非面状结构的方向凹陷设置。如此,通过该一体式非面状结构装配入面状结构内,通过二者的接触配合,从而提高了储电柜100线面密封的可靠性。
请参阅图5,根据本申请的一些实施例,第一密封凸条具有嵌入部,第一密封面具有弹性形变部,嵌入部与弹性形变部可嵌入式配合。
本实施例中,第一密封凸条和第一密封面之间的配合安装方式,可以包括但不限于为胶粘、嵌入、卡合等方式。其中,通过将第一密封凸条嵌入第一密封面内,可以便于密封面的快速装配,灵活性高,并且易拆卸,从而有效确保安装效率。
本实施例中,嵌入式密封凸条与密封面的压紧配合以实现线面密封。其中,密封凸条嵌入密封面后,密封凸条的压缩量,以及密封凸条嵌入至密封面的深度,需保证该线面密封的牢靠性。该线面密封的具体实现方式中,可以设计密封凸条和密封面中的其中一者为弹性件,另一者为刚性件,例如,可以是弹性密封面配刚性密封凸条,也可以是刚性密封面配合弹性密封凸条。
在一些具体的实施例中,柜门外框101的四周边缘,沿朝指向门扇外框201的方向,弯折形成弯折部,该弯折部即为第一密封凸条;第一密封面可以为粘贴于门扇外框201上的胶垫、胶条等弹性结构件,弯折部能够嵌入弹性结构件中,从而门扇2在关闭状态,第一密封凸条嵌入第一密封面内。
请参阅图3-图5,根据本申请的一些实施例,柜门外框101具有沿柜门外框101的周向设置的第二连接部10102,第二连接部10102围设于第一连接部10101的外侧;
门扇外框201具有沿门扇外框201的周向设置的第二配合部20102,第二配合部20102围设于第一配合部20101的外侧,第二连接部10102与第二配合部20102密封连接。
本申请实施例的技术方案,第二连接部10102与第二配合部20102气密装配,形成第二密封单元。在一些具体的实施例中,第二连接部10102可以为粘贴于柜门外框101上的密封胶条,第二配合部20102为门扇外框201的表面,该门扇外框201的表面与该密封胶条一一配合。或者,第二连接部10102为柜门外框101的表面,第二配合部20102为粘贴于门扇外框201上的密封胶条,该柜门外框101的表面与该密封胶条一一配合。
本申请实施例中,第二密封单元可以用于与第一密封单元同时工作,使储电柜100柜门与门扇2之间实现双层密封,以提高密封效果。此外,第二密封单元还可以用于当第一密封单元密封失效时,对储电 柜100进行补充密封,以提高密封可靠性。
在一些实施例中,根据实际需要,可以灵活设计第二连接部10102和第二配合部20102的配合方式,例如,将二者的接触部设计为线面密封或面面密封。其中,面面密封是指,第二连接部10102和第二配合部20102用于与对方相配合安装的接触部的端面结构均为面状体结构,在二者相交接的接触部位置处,通过面状体结构与面状体结构的接触,以实现柜门外框101与门扇外框201的面面接触式气密装配。此外,第二连接部10102与第二配合部20102的线面密封,同前文所提及第一密封凸条与第一密封面的线面密封技术,此处不再赘述。
在一些实施例中,为提高密封性能,储电柜100还可以设计为三层及三层以上的多层密封结构,例如,储电柜100包括一个第一密封单元和两个第二密封单元,其中,第一密封单元包括设于柜门外框101的内边缘的密封凸条,以及包括粘贴于门扇外框201的密封面;第二密封单元包括粘贴于柜门外框101和门扇外框201的,相配合使用的两对密封面。为便于密封单元的制造装配,相邻的各密封单元等间隔排布。
根据本申请的一些实施例,第二连接部10102与第二配合部20102之一为第二密封凸条,第二连接部10102与第二配合部20102之另一为第二密封面,第二密封凸条与第二密封面密封接触以实现线面密封。
相较于面面密封,线面密封具有良好的密封效果,故,本申请实施例中,将第一连接部10101与第一配合部20101之间的密封、第二连接部10102和第二配合部20102之间的密封,均设计为密封凸条与密封面相结合的线面密封方式,以利用双层线面密封,进一步提高储电柜100气密效果。
本申请实施例的技术方案中,根据实际需要,可以灵活设计第一连接部10101与第一配合部20101之间、第二连接部10102与第二配合部20102之间的线面密封的实现方式。其中,第二密封凸条与第二密封面之间的线面密封,同样参考同前文所提及第一连接部10101与第一配合部20101的密封技术中,第一密封凸条与第一密封面的线面密封,此处不再赘述。
在一个具体的实施例中,第一连接部10101为第一密封凸条,第一配合部20101为第一密封面,第一密封凸条能够装配至第一密封面内,以实现第一连接部10101与第一配合部20101之间为线面密封;第二连接部10102为第二密封面,第二配合部20102为第二密封凸条,第二密封凸条能够装配至第二密封面内,以实现第二连接部10102与第二配合部20102之间为面线密封。如此,借助双层密封结构都是线面接触式密封技术,以进一步提高储电柜100的密封性能。
请参阅图3-图5,根据本申请的一些实施例,第一连接部10101为第一密封凸条,第一配合部20101为第一密封面;第二连接部10102为第一配合面,与第二配合部20102为第二配合面。
对于大型储电柜100,由于储电柜100尺寸较大,在其上加工凸条,密封难度大,并且,由于门扇2通常为扁平薄板,其整体强度低于储电柜100柜体1,故,本申请实施例的技术方案中,将密封凸条仅设置于柜门外框101,而在门扇外框201上仅设置面状结构,即,采用线面密封和面面密封的混合式密封方式。如此,在由线面密封带来的良好密封性能的情况下,同时降低了密封凸条的加工难度,有利于大型储电柜100密封技术的实现,同时还避免了由于在门扇2上设置密封凸条,导致门扇2整体强度降低进而降低储电柜100气密性的问题。
此外,为降低柜门外框101上密封结构的加工难度,在另一些实施例中还可以将密封凸条仅设置于门扇外框201,即仅在第一连接部10101或第二连接部10102的其中一者,设置密封凸条,从而通过线面密封和面面密封。
请参阅图3-图5,根据本申请的一些实施例,所述第一连接部10101设于所述柜门外框101的内边缘,所述第二连接部10102设于所述柜门外框101的外边缘。
值得说明的是,本申请所有实施例中,柜门外框101的内边缘,指柜门外框101靠近柜体1的内部的一侧的边缘;柜门外框101的外边缘指柜门外框101靠近柜体1的外部的一侧的边缘;门扇外框201的内侧边缘指门扇外框201靠近柜体1的内部的一侧的边缘;门扇外框201的外边缘指门扇外框201靠近柜体1的外部的一侧的边缘。
示例性的,第一密封凸条设于柜门外框101的内边缘,第一配合面设于柜门外框101的外边缘。
由于柜门外框101或门扇外框201往往通过将其外侧边缘装订至柜门或门扇2上,内侧边缘处则无柜门或门扇2实体,在内侧边缘加工第一密封凸条的难度,远小于在外侧边缘加工第一密封凸条的难度。基于此,为兼顾线面密封的加工难度,本实施例通过将配合面套设于第一密封凸条的外侧,以减小该密封凸条的加工难度。
本实施例的技术方案中,针对柜门外框101具有密封凸条的情形,通过将第一密封凸条设计为位于柜门外框101的内侧边缘,第一配合面位于柜门外框101的外侧边缘,可以便于在柜门外框101的基体上,通过对柜门外框101的边缘进行卷边等方式,在柜门外框101上一体成型制作出第一密封凸条,从而降低密封凸条在储电柜100柜门上的加工难度。
本实施例借助在储电柜100的柜体1和门扇2之间,通过由柜门外框101的内圈翻边形成的密封凸条结构和增设的外圈密封条,外圈密封条和门扇外框201的平面段紧压,实现内圈线面接触密封、外圈面面接触密封的双层密封结构,实现稳定的柜体1气密。
此外,对于采用线面密封和面面密封组合的双层密封的其余情形,例如,当密封凸条设于门扇外框201时,为方便带密封凸条结构在门扇外框201的生产组装,同样可以将密封凸条布设于门扇外框201的内侧边缘,即,对门扇外框201的边缘进行翻折卷边。
请参阅图4,根据本申请的一些实施例,所述第一配合部20101为横截面呈方形的密封圈;所述第二连接部10102为所述柜门外框101的表面的一部分,第二配合部20102为横截面呈弧形的密封圈。
示例性的,第一密封面为横截面呈方形的密封圈,第一配合面为柜门外框101的表面的一部分,第二配合面为横截面呈弧形的密封圈,密封圈的曲边与第一配合面密封接触。
本申请实施例的技术方案,第二密封单元中,第一配合面与第二配合面的接触,即柜门外框101所在平面,与弧形密封圈的圆弧顶点所在直线之间的接触,可视为线面接触。基于此,又由于第一密封单元的密封方式为密封凸条与密封面构成的线面接触式密封,因而本实施例实质可以理解为双层线面密封。
其中,由于方形横截面、弧形横截面的密封圈均可以选为标准件,例如,弧形密封圈沿可以选择为断面呈半圆形的市售标准密封圈,因此,本实施例中实现了储电柜100低成本,易制造,且密封佳的密封技术,解决了大型储电柜100密封复杂及密封难的问题。
一些实施例中,第一密封面、第一配合面或第二配合面中至少一者为设于柜门外框101的胶垫;和/或,第一密封面、第一配合面或第二配合面中至少一者为设于门扇外框201的胶垫。
对于线面密封和面面密封,将接触部中的面状体结构设置为胶垫,可以更有利制造,且由于胶垫成本低,从而可以进一步降低储电柜100密封成本。在一些实施例中,根据实际需要,胶垫可以设置于柜门外框101或门扇外框201上。
例如,对于面面密封式第二连接部10102和第二配合部20102,其中,第一配合面可以为设于柜门外框101的胶垫,第二配合面可以为设于门扇外框201的胶垫。再如,对于线面密封的第一连接部10101和第一配合部20101,其中,第二密封面可以为设于门扇外框201的胶垫。
请参阅图3-图5,根据本申请的一些实施例,第一密封面、第一配合面或第二配合面中至少一者为柜门外框101的表面的一部分;和/或,第一密封面、第一配合面或第二配合面中至少一者为门扇外框201的表面的一部分。
对于线面密封和面面密封,将接触部中的面状体结构,设计为储电柜100的柜门外框101或者门扇外框201表面的一部分,由于面状体结构为柜门外框101或者门扇外框201的一部分,无需单独增设密封件,因此可以提高储电柜100的气密性,并且可以维持更长时间的有效密封。
请参阅图3-图5,根据本申请的一些实施例,第一连接部10101于柜门外框101的表面沿柜门外框101的周向以朝向门扇外框201的方向突出形成。
示例性的,第一密封凸条基于柜门外框101的表面沿柜门外框101的周向以朝向门扇外框201的方向突出形成。
本实施例中,对于第一连接部10101,沿柜门外框101的周向方向,将在柜门外框101的外侧边缘,向外翻折,卷起形成凸起结构,即形成第一密封凸条,以作为接触部的非面状体结构。由于密封凸A与柜门外框101一体制作,可以有效提高密封凸条的气密性。
请参阅图3-图5,根据本申请的一些实施例,所述第二连接部10102第二密封凸条基于所述门扇外框201的表面沿所述门扇外框201的周向以朝向所述柜门外框101的方向突出形成。
示例性的,第二密封凸条基于门扇外框201的表面沿门扇外框201的周向以朝向柜门外框101的方向突出形成。
对于第二连接部10102或第二配合部20102,当密封凸条设置于门扇外框201时,沿门扇外框201的周向方向,将在门扇外框201的外侧边缘,向外翻折,卷起形成凸起结构,即形成第二密封凸条,以作 为接触部的非面状体结构。由于密封凸B条与门扇外框201一体制作,可以有效提高密封凸条的气密性。
请参阅图4,根据本申请的一些实施例,第一密封凸条包括凸条本体T,以及基于凸条本体T朝背离门扇2的方向弯折形成的折叠部M。
其中,折叠部M与凸条本体T呈一定夹角,使折叠部M能嵌入第一配合部20101内。其中,该夹角可以为0-90°。为使折叠部M具备足够强度,该夹角优选为0°-10°,即折叠部M与凸条本体T完全重合或接近重合。
具体地,当第一连接部10101设于柜门外框101的内边缘,基于柜门外框101的内边缘,并朝指向门扇外框201的方向多次弯折形成折叠部M;或者,当第一配合部20101设于门扇外框201的内边缘,基于门扇外框201的内边缘,并朝指向门扇外框201的方向多次弯折形成折叠部M。
门扇2关闭过程中,通过将第一连接部10101嵌入第一密封面内,或者,第一配合部20101嵌入第一连接部10101内,从而实现第一连接部10101与第一密封面之间的线面密封,以提高门扇2与柜门之间的牢固度。折叠部M可以增加各连接部与相应配合部之间的接触面积,使各连接部与相应配合部之间的接触更紧贴牢靠,从而提高气密性效果以及密封持久性。
本申请实施例技术方案中,通过在第一连接部10101或第一配合部20101上设置折叠部M,以提高密封效果的持久性。
请参阅图4~图5,根据本申请的一些实施例,门扇外框201具有用于放置第二配合部20102的安装凸台H;
沿安装凸台H的凸起方向,凸条本体T的尺寸x与第一配合部20101的尺寸y之和为h1,安装凸台H的尺寸与第二配合部20102的尺寸之和为h2;h1与h2之差小于预设阈值。
本实施例中h1、h2的调节方法有多种可能的实施方式,例如,沿第一连接部10101指向第一配合部20101的方向,改变第一连接部10101凸起的凸起段的长度,即改变凸条本体T的长度;又如,沿门扇外框201指向柜门外框101的方向,改变门扇外框201的用于安装第二配合部20102的凸起段的尺寸,即改变安装凸条H的高度;再如,改变第一配合部20101的厚度、改变第二配合部20102的厚度。如此,在门扇2关闭状态下,使第一配合部20101和第二配合20102部均能被压缩,并借此弥补关门密封状态下第一配合部20101和第二配合部201012的挤压型变量误差,从而实现两个密封部的同时密封,以加强柜体1的密封效果。
根据储电柜100的实际应用场景,预设阈值可以设定至允许取值范围内,以借助各连接部与配合部的尺寸差,吸收密封结构的弹性变形误差量。示例性的,预设阈值可以设为0,即h1与h2相等。
请参阅图3和图6,根据本申请的一些实施例,储电柜100还包括铰接组件4;铰接组件4包括设于门扇外框201和柜门外框101之一上的动铰链401,以及设于门扇外框201和柜门外框101之另一上的静铰链402;动铰链401的铰接端与静铰链402的铰接端通过铰链轴403连接。
本实施例的技术方案中,通过在将柜体1与门扇2之间设置铰接组件4,动铰链401的铰接端,与静铰链402的铰接端之间通过铰链轴403铰接连接,从而利用铰链结构实现门扇2与柜门之间的铰接连接,以提高柜体1与门扇2之间的连接稳固性,从而提高柜体1的气密性。
请参阅图3和图6,根据本申请的一些实施例,动铰链401的非铰接端和静铰链402的非铰接端通过锁止组件锁合;锁止组件包括设于动铰链401和静铰链402的其中一者上的锁止件404,以及设于动铰链401和静铰链402的另一者上且与锁止件404对应设置的锁孔405。
对于高压柜体,由于柜体1内部气压高于柜体1外部气压,受压差作用,门扇2易发生形变、位移,导致铰链结构中动铰链401朝着静铰链402的方向发生位移,从而铰链轴403转动,门扇2与柜体1之间产生间隙,该间隙将影响储电柜100的气密性。
鉴于此,本实施例设计动铰链401和静铰链402的非铰接端增设锁止组件,以使动铰链401和静铰链402通过锁止组件锁合。利用锁止组件,使铰链轴403的端部通过锁止组件限位止挡。当铰链闭合后,利用锁止组件对动铰链401限位止挡,减小由于铰链轴403转动导致门扇2与柜体1之间产生的微小缝隙,从而有效确保了气密效果。
为便于重复开门及维护,在一些实施例中,锁止件404可以为螺钉,锁孔405可以为螺纹孔,螺钉插入螺纹孔内,可固定锁止铰链结构,防止铰链松动,可更好的保证密封效果。
请参阅图3和图6,根据本申请的一些实施例,静铰链402设有限位台阶G,限位台阶G用于约束锁 止件404,锁孔405设于所述限位台阶G的表面。
本申请实施例中,通过将锁孔405设于限位台阶G上,借助限位台阶G的高度,以控制锁止件404旋入静铰链402的深度,以提高门扇2与柜体1的装配气密性。
请参阅图6,根据本申请的一些实施例,沿与铰链轴403的轴向,锁止件404和锁孔405分别居中设置于动铰链401和静铰链402上。
根据实际需要,锁止件404可以设于铰链结构的任意位置。例如,由于锁止件404在锁合打开的过程中,易受锁孔405孔壁的阻挡,可以将锁止件404设于动铰链401,将锁孔405设于静铰链402,以便于灵活锁合锁止件404或解锁锁止件404。此外,考虑到受力均衡,优选将锁止件404设于动铰链401或静铰链402的居中位置。
请参阅图3和图7,根据本申请的一些实施例,储电柜100还包括门托组件6,门托组件6包括设于柜门外框101的底部的门托本体601。
经长时间使用,门扇2相对储电柜100的柜体1发生位移,门扇2松脱下坠,密封效果降低,长期使用甚至有安全事故风险。
本实施例门托组件6包括门托本体601,门托本体601连接在储电柜100的柜门外框101的底部。门托本体601的上表面设有一承托面。在门扇2正常关闭情况下,承托面的高度,可以等于或略高于门扇2最底部处下表面的高度。当门扇2在关闭状态下,门扇2的该下表面与门托本体601的承托面接触,从而门托本体601为门扇2提供一个向上的支撑力,门托本体601向上托住门扇2。采用上述技术方案,通过在储电柜100上设置门托组件6,当门扇2关闭后,利用门托本体601可以对门扇2起到支撑作用,使得门扇2能够处于正常关闭的状态,有效解决了门扇2用久以后就松脱下垂的问题。
请参阅图7和图8,根据本申请的一些实施例,门托组件6还可以包括设于门扇外框201的底部的滚轮组件602。

为提高密封效果,本实施例在储电柜100的柜门外框101与门扇外框201上增设固定组件7。具体地,在门扇2处于关闭状态时,本实施例可以通过调节螺栓组件701旋入柜体1的深度,以协调控制第一连接部10101与第一配合部20101的受挤压变形度、第二连接部10102与第二配合部20102的受挤压变形度,从而使门扇外框201与柜门外框101呈大致平行状态,通过将限位件702与螺栓组件701配合,以将门扇2锁合固定至柜体1。
由此,借助限位件702与螺栓组件701的配合使用,以调节储电柜100的各密封结构,以使储电柜100达到更佳的气密效果。值得说明的是,该螺栓组件701的旋紧,不能过松,也不能过紧,需保障密闭状态下门扇外框201与柜门外框101呈大致平行的状态。
在一些实施例中,螺栓组件701、限位件702均可以通过焊接、铆接等机械连接方式安装在门扇外框201/柜门外框101上。此外,本实施例中,借助本固定组件7,还可以,实现对门扇2限位固定作用,使得储电柜100密闭状态下,门扇2及柜门四周均被锁死,避免了门扇2因受到冲击力出现松动的现象,提高了门扇2的防爆能力,储电柜100的气密可靠性得到进一步保障。请参阅图9和图10,根据本申请的一些实施例,螺栓组件701包括活节螺栓70101和固定螺母70102。
本实施例中,活节螺栓70101可转动,与固定螺母70102配套使用,起到对门扇2的固定作用。活节螺栓70101安装起来简单方便,降低了储电柜100气密装配的难度。

固定组件7的安装无需对柜体1的柜门结构进行改变,按照能够与行业标准尺寸进行适配,遵循储电柜100标准产品的尺寸,保证产品通用性。一些实施例中,活接螺栓可以采用标准件。
请参阅图9和图10,根据本申请的一些实施例,限位件702包括一平板,平板远离门扇2的一端设有凹陷部N,凹陷部N用于容纳活节螺栓70101。
本实施例中,活节螺栓70101的一端固定至柜体1,例如,固定至柜门外框101上。门扇2闭合状态下,旋转活节螺栓70101,将活节螺栓70101的另一端拨至限位件702的凹陷部N内,并在该另一端上旋入固定螺母70102,直至固定螺母70102抵靠于限位件702,从而利用固定螺母70102将活节螺栓70101旋紧固定。
利用凹陷部N,以对活节螺栓70101在平行于柜门所在平面方向的位移、晃动进行限位,以提升螺栓组件701与限位件702的装配稳固性,从而提升柜体1的密封气密效果。
在一些实施例中,螺栓组件701还包括螺栓安装架70103,螺栓安装架70103用于将活节螺栓70101安装至柜体1。
本实施例借助螺栓安装架70103,可以实现将螺栓组件701安装至柜体1上,当门扇2需要关闭时,轻轻拨动螺栓即可实现门扇2的锁止固定,提高了储电柜100整体的装配灵活度。
在一些实施例中,螺栓组件701还包括销钉70104,销钉70104穿设于螺栓安装架70103内。借助销钉70104,将活节螺栓70101转动连接至螺栓安装架70103,并将螺栓安装架70103固定至柜门外框101。由此,借助固定组件7,将门扇2锁止于柜门上。
在一些实施例中,螺栓组件701还包括止挡件70105,销钉70104穿设于螺栓安装架70103内,止挡件70105设于销钉70104上的端部。借助止挡件70105,对销钉70104的转动进行限位,从而提高螺栓组件701与限位件702的装配稳定性,从而进一步提高储电柜100气密效果。在一些实施例中,螺栓安装架70103由三块板状件构成,各板状件围合形成一容纳腔S,容纳腔S为活节螺栓70101提供可转动空间。
在一些实施例中,限位件702焊接在门扇2的边缘,螺栓安装架70103焊接在柜门的边缘,活节螺栓70101的一端通过销钉70104转动连接至螺栓安装架70103,从而借助螺栓安装架70103,将活节螺栓70101的该一端稳固安装至柜门,提高储电柜100的气密装配灵活度。
请参阅图3,根据本申请的一些实施例,固定组件7为多个,各螺栓组件701呈等间距分布于柜门外框101的周缘,各限位件702呈等间距分布于门扇外框201的周缘。
本实施例通过在柜门四周间隔设置多个固定组件7,各螺栓组件701与相应限位件702相互锁止配合,实现柜体1的多点锁止。多个间隔设置的固定组件7,使柜门受力更加合理,储电柜100能够均匀承受压力,因而可以承受更大的冲击力,提高了柜门锁止可靠性。
根据实际需要,限位件702和活节螺栓70101的布设方式,可以灵活设计为位于柜门周缘。一些实施例中,螺栓组件701对称分布于柜门外框101的上侧边缘和下侧边缘,当柜门外框101的左侧边缘为铰接组件4中静铰链402所在一侧,则柜门外框101的右侧边缘均匀分布有多个螺栓组件701。
根据本申请的一些实施例,门扇外框201和/或柜门外框101为经多次弯折的一体式钣金结构件。
本实施例中,柜门外框101或门扇外框201可以由一块钣金经冲压或辊压,多次弯折形成。例如,边框断面为闭合的四边形框体,且第一折边、第二折边、第三折边以及第一限位凸起均为实心结构,从而使储电柜100门扇外框201和/或柜门外框101具有较高的强度,结构更加稳固,在受到外力时不容易产生变形。而且钣金结构件为金属材质,一体成型,厚度均一,高压强磁环境下提高柜体1内部的抗电磁干扰性能。
在一些实施例中,柜体1内的气压大于柜体1外的气压。
为提高储电柜100阻燃效果,储电柜100内部往往充有氮气或者其它惰性气体。本申请实施例通过将柜内气压设为大于柜外气压,以减少外部空气进入箱体内部,并有利于柜内气体往外流出至柜体1外部,减少了柜内助燃气体的含量,从而有利于提供柜内阻燃环境。
示例性的,储电柜100置于大气压环境中,柜体1内的气压为1.5-5倍标准大气压。
请参阅图2和图9,根据本申请的一些实施例中,柜体1包括气体管路连接口5。
储电柜100往往由于制造时结构加工误差,导致气密性仍然达不到用户要求,或者,长期使用导致储电柜100密封失效等,便于柜内气体交换。一些实施例中,通过在柜体1的底部设置气体管路连接口5,柜体1的顶部设有出气口3,以便于从柜体1的底部充入呈惰性气体,并从柜体1的顶部流出柜内已有气 氛,将柜体1内空气快速置换为氮气或者其它惰性气体。
本申请实施例实现了柜体1内部气体的实时置换,尽可能提高了柜体1内部惰性气体的含量,实现了柜体1内部可靠的动态阻燃环境,降低由于微量空气进入柜体1内,导致柜内空气达到一定浓度从而引发储电柜100爆炸的可能性。
在一些实施例中,储电柜100为长宽高分别为0.6m~1m;1m~1.5m;1.5m~2.5m的长方体结构。
相关技术中,大体积储电柜100,柜体1的棱边需满焊,由于焊缝很多,钢板很薄,产品一致性不高等原因,储电柜100密封难度较大。本申请实施例的密封技术应用至该类大型储电柜100,例如,对于长、宽、高分别为0.6m~1m、1m~1.5m、1.5m~2.5m的长方体状储电柜100,可以实现大型储电柜100的良好气密。具体地,储电柜100为长可以为0.6m、0.7m、0.8m、0.9m、1m;宽可以为1m、1.1m、1.2m、1.3m、1.4m、1.5m;高可以为1.5m、1.6m、1.7m、1.8m、1.9m、2.0m、2.1m、2.2m、2.3m、2.4m、2.5m。
一些实施例中,柜体1包括但不限于为六面体状,还可能是圆柱柜,棱柱柜等,门扇2包括但不限于是侧面开闭方式,还可能是上下面开闭方式。
本方案克服了传统大型储电柜需在柜体1内壁粘贴防火棉才能实现消防安全的问题,解决了传统大型储电柜由于受到门扇外框201和柜门外框101折弯精度的限制,门扇2与柜门之间的配合间隙很难控制到预期范围,导致门扇2与柜门之间的密封连接难度大,储电柜100整体气密性难以达到预计预期的问题。
在一些实施例中,所述储电柜100内放置有至少一个电池包箱体组。
本申请实施例中,储电柜100可以包括但不限于为具有容纳空间的柜体式储能装置1000,该容纳空间内可以放置一个或多个电箱。
本申请实施例的储电柜100密封技术尤其适用于大型储电柜100的密封,例如适用于放置有3~8个电箱的柜体式储能装置1000,该类储能装置1000由于内部能量高度集中,通过采用本申请实施例的密封技术,例如柜体1与门扇2之间采用双层线密封,可以实现该高能量大型储电柜100的良好密封。具体地,电箱的个数可以为3个,4个,5个,6个,7个,8个,等等。
