Description

一种存储运输装置
本申请要求于2021年11月26日申请的、申请号为202122943005.6的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及存储运输设备技术领域,尤其涉及一种存储运输装置。
背景技术
二次电池具有能量密度大、输出功率高、充放电寿命长、无污染、工作温度范围宽及自放电小等诸多优点。其作为新型的高能化学电源,近年来,二次电池广泛应用于手机、电脑和电动汽车等领域,二次电池具有续航时间长、使用寿命长、自放电率低和绿色环保等优点。
电池极片是二次电池的重要组成部分,是二次电池生产过程中非常重要的环节,是二次电池的核心。在二次电池的生产过程中,一般需要对电池极片进行存储、转运、烘干等多个周转操作步骤。在这些周转操作步骤中,电池极片直接与外界空气发生接触,外界空气的湿度会影响电池极片中的水分含量,进而影响到最终制备的二次电池的安全和性能。
技术问题
鉴于二次电池的安全和性能问题,本申请实施例提供了一种存储运输装置,能够保证该存储运输装置内的湿度不发生变化,进而保证电池极片的水分含量,保证制备出的二次电池的安全和性能。
技术解决方案
根据本申请实施例的一个方面,提供了一种存储运输装置,包括外罩、支撑板和密封胶。支撑板盖合于外罩的开口,以形成容纳待运输物的空间。该存储运输装置还包括第一容胶槽和第二容胶槽,第一容胶槽设置于外罩和支撑板的密封连接处,密封胶包括第一部分和第二部分,第一部分和第二部分分别位于第一容胶槽和第二容胶槽内,且第一部分和第二部分相连接。密封胶用于密封外罩和支撑板。
在一些实施例中,第一容胶槽和第二容胶槽连通。
通过上述方案,使得第一容胶槽中的密封胶和第二容胶槽中的密封胶可以互相流通。在盖合外罩与支撑板时,从第一容胶槽溢出的密封胶可以流至第二容胶槽,从第二容胶槽溢出的密封胶也可以流至第一容胶槽,便于密封胶存留在外罩与支撑板的间隙中,而不至于被挤压至间隙外,从而有利于提高存储运输装置的密封性。
在一些实施例中,第一容胶槽和第二容胶槽均沿外罩的周向设置在外罩的开口端。
该方案提供了一种第一容胶槽和第二容胶槽的设置方式。这两个容胶槽中均容纳有密封胶,且这两个容胶槽中的密封胶相连接,相连接的密封胶填充在外罩和支撑板的密封连接处的间隙,可以密封该间隙,从而增加外罩和支撑板之间的透水路径,有效阻断水汽通路,减少水汽进入的可能,以保证该存储运输装置内的湿度不发生变化。
在一些实施例中,第一容胶槽和第二容胶槽均沿外罩的周向设置在支撑板上。
该方案提供了另一种第一容胶槽和第二容胶槽的设置方式。支撑板的板面较大,在支撑板上设置第一容胶槽和第二容胶槽,可以降低因外罩的开口端在密封连接处尺寸有限而较难同时设置第一容胶槽和第二容胶槽的风险。
在一些实施例中,第一容胶槽和第二容胶槽中的一者沿外罩的周向设置于外罩的开口端,第一容胶槽和第二容胶槽中的另一者沿外罩的周向设置于支撑板上。
该方案提供了又一种第一容胶槽和第二容胶槽的设置方式,将第一容胶槽和第二容胶槽分别设置在外罩的开口端和支撑板上,可以降低因外罩的开口端或支撑板在密封连接处尺寸有限而无法同时设置第一容胶槽和第二容胶槽的风险,也可以避免将第一容胶槽和第二容胶槽集中设置在外罩或支撑板上而使外罩或支撑板的强度不达标。
在一些实施例中,第二容胶槽的数量为多个,多个第二容胶槽错开设置。
多个第二容胶槽错开设置,如果多个第二容胶槽均涂满密封胶,这多个第二容胶槽中的密封胶会存留在外罩和支撑板的间隙中的不同位置,可以增大密封连接处的密封面积,有利于提高存储运输装置的密封性。
在一些实施例中,第二容胶槽的数量为多个时,外罩的开口端和支撑板均设置有第二容胶槽。
第二容胶槽分开设置在外罩的开口端和支撑板上,可以降低因外罩的开口端或支撑板在密封连接处尺寸有限而无法设置多个第二容胶槽的风险,也可以避免将多个第二容胶槽集中设置在外罩或支撑板上而使外罩或支撑板的强度不达标。
在一些实施例中,密封连接处还设置有插接件,插接件具有相对的第一端和第二端,第一端与外罩或支撑板连接,第二端伸入第一容胶槽内。
通过上述方案,插接件的第二端伸入第一容胶槽内,可以挤压第一容胶槽内的密封胶,是的第一容胶槽内的密封胶易于溢至蜜蜂连接处,以增加密封连接处的存胶量,从而提高存储运输装置的密封效果。另外,插接件的第二端伸入第一容胶槽内,外界水汽要绕过插接件的第二端才有可能进入存储运输装置内,增加了密封连接处的透水路径,便于有效阻断水汽通路,减少水汽进入的可能,以保证该存储运输装置内的湿度不发生变化。
在一些实施例中,插接件为沿外罩的周向延伸的环状结构,插接件连接于外罩或支撑板。
通过上述方案,插接件可以沿外罩的周向在各个位置处挤压第一容胶槽或第二容胶槽内的密封胶,使得第一容胶槽或第二容胶槽内的密封胶易于溢至密封连接处,可以提高密封胶的密封效果。另外,插接件可以沿外罩的周向整周伸入第一容胶槽或第二容胶槽,沿外罩的周向整周的外界水汽均要绕过插接件的第二端才有可能进入存储运输装置内,使得插接件沿外罩的周向各个位置均能增加透水路径,便于进一步有效阻断水汽通路,减少水汽进入的可能,以保证该存储运输装置内的湿度不发生变化。
在一些实施例中,当插接件的第二端伸入第一容胶槽时,插接件的第二端与第一容胶槽的槽底具有间距。
通过上述方案,不会在该间距处将透水路径中断,从而不会影响插接件发挥提高密封性的效果。
在一些实施例中,存储运输装置还包括锁紧机构,锁紧机构用于锁紧外罩和支撑板。
通过锁紧机构锁紧外罩和支撑板,可以增加外罩和支撑板连接的牢靠性,避免运输时外罩和支撑板发生连接失效而产生缝隙无法起到密封效果。另外,在锁紧时会挤压第一容胶槽、第二容胶槽和密封连接处的密封胶,密封胶在挤压作用下易于较大面积且均匀分布在密封连接处,利于提高密封胶的密封效果。
在一些实施例中,外罩的开口端沿周向设置有连接件,连接件凸出于外罩的外壁,连接件用于连接外罩和支撑板,且连接件与密封胶接触。
通过上述方案,可以增大外罩与支撑板的接触面,从而便于锁紧外罩和支撑板,避免运输时外罩和支撑板发生连接失效而无法起到密封效果。连接件与密封胶接触,可以增大外罩和支撑板的密封面积,有效阻断水汽通路,减少水汽进入的可能,以保证该存储运输装置内的湿度不发生变化。

有益效果

极片是二次电池的重要组成部分,是二次电池生产过程中非常重要的环节,是二次电池的核心。在二次电池的生产过程中,一般需要对极片进行存储、转运等多个周转操作步骤。在这些周转操作步骤中,若极片中的水分含量过高,会腐蚀集流体;并且水分子残留在极片上,会导致电解液吸水分解,从而产生HF,腐蚀极片,最终造成二次电池的循环性能变差,甚至发生安全事故。
相关技术采用存储运输装置对极片进行存储和运输。存储运输装置包括箱体,箱体具有两个立开门,打开两个立开门后可以将极片安置在箱体内的支撑结构上,安置好极片后关闭两个立开门实现对箱体的密封。其中,两个立开门之间有门缝,相关技术采用橡胶或硅胶做贴合面密封圈,通过两个立开门闭合时挤压橡胶或硅胶来实现对门缝的密封。另外,相关技术还在箱体的内底部放置干燥剂,通过五氧化二磷等干燥剂对箱体内的环境进行干燥,防止极片在存储、运输的过程中吸水。
申请人发现,相关技术通过密封圈密封立开门,密封圈与立开门之间存在较多间隙,该间隙为箱体外的水汽的进入提供了通道,箱体外的水汽经过该通道后可以进入箱体内,因此该存储运输装置密封性不够好,无法有效隔绝水汽。另外,相关技术在箱体内放置干燥剂来控制箱体内的水汽,但干燥剂只能短时间内保持箱体内的干燥。在长时间存储和运输过程中,箱体内的极片与干燥剂同时吸收箱体内的水汽,当干燥剂吸收水汽达到上限后,箱体内的水汽会被极片吸收,导致极片过度吸水,因此放置干燥剂无法长时间保证箱体内的湿度不发生变化,并不能有效控制极片的吸水量。综上,相关技术提供的存储运输装置并不能有效隔绝水汽,无法保证极片长时间的干燥存储和运输。
基于此,本申请实施例提供一种存储运输装置,将第一容胶槽设置于外罩和支撑板的密封连接处,第一容胶槽和第二容胶槽内分别容纳有一部分密封胶,本申请通过相连接的这两部分密封胶密封外罩和支撑板的间隙,有效阻断水汽通路,减少外界环境的水汽进入存储运输装置的可能,从而起到良好的密封效果,以保证该存储运输装置内的湿度不发生变化。本申请并不依赖干燥剂控制存储运输装置内的湿度,因此适用于长时间的干燥存储运输。
本申请实施例提供的存储运输装置可以用于存储任意对含水量有要求的待运输物。例如,待运输物可以是极片。该极片可以是二次电池中的正极片或负极片,该二次电池可以是包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。例如,本申请中所提到的二次电池可以包括电池模块或电池包等。本申请中所提到的二次电池可以是方壳电池、圆柱电池等。该二次电池可以用于为用电装置提供电能。其中,用电装置可以是汽车、手机、便携式设备、笔记本电脑、轮船、航天器、电动玩具和电动工具等等。汽车可以是燃油汽车、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;航天器包括飞机、火箭、航天飞机和宇宙飞船等等;电动玩具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;电动工具包括金属切削电动工具、研磨电动工具、装配电动工具和铁道用电动工具,例如,电钻、电动砂轮机、电动扳手、电动螺丝刀、电锤、冲击电钻、混凝土振动器和电刨等等。本申请实施例对上述用电装置不做特殊限制。
下面结合附图对本申请实施例提供的存储运输装置进行详细说明。图1是本申请实施例提供的一种存储运输装置的结构示意图,图2是图1中A的局部放大图,图3是本申请实施例提供的另一种存储运输装置的结构示意图,图4是本申请实施例提供的一种支撑板2的结构示意图,图5是图4中B的局部放大图,图6至图9是本申请实施例提供的四种第一容胶槽3和第二容胶槽4的结构示意图。
如图1至图9所示,本申请提供了一种存储运输装置,该存储运输装置包括:外罩1、支撑板2和密封胶。外罩1具有开口11,支撑板2盖合于开口11,以形成容纳待运输物的空间。该存储运输装置还包括第一容胶槽3和第二容胶槽4,第一容胶槽3设置于外罩1和支撑板2的密封连接处,密封胶包括第一部分和第二部分,第一部分和第二部分分别位于第一容胶槽3和第二容胶槽4内,且第一部分和第二部分相连接,密封胶用于密封外罩1和支撑板2。
外罩1是配合支撑板2以形成容纳待运输物的空间的组件。外罩1可以是一端开口的空心结构,外罩1的形状可以是长方体形、正方体形、圆柱体形、六棱柱形等,本申请实施例对此不做限定。外罩1可以是多个板件拼接而成,为了避免拼接时产生缝隙,而为水汽进入提供通道,外罩1也可以是一体成型。外罩1的大小可以根据待运输物的大小来确定。其中,待运输物可以是任意一种对含水量有要求的物件,例如,待运输物可以是二次电池中的极片,该极片可以是正极片或负极片。外罩1的材质可以是多种,比如ABS、橡胶等,为了进一步提高存储运输装置的密封性,外罩1还可以选用透水率更小的金属材料制成。
支撑板2为板状结构,支撑板2的形状可以是长方体形、正方体形、圆柱体形等,支撑板2的形状可以与外罩1横截面的形状相同,当然,也可以不相同。支撑板2的板面可以大于外罩1的开口11尺寸,使得支撑板2盖合于外罩1的开口端12时可以完全封堵开口11,以形成容纳待运输物的空间。支撑板2也可以是ABS、橡胶等材料制成,为了进一步提高存储运输装置的密封性,支撑板2也可以选用透水率更小的金属材料制成。当外罩1和支撑板2均采用金属材料制成时,该存储运输装置的密封等级可以达到较高的密封等级,可以从材料角度隔绝水汽进入该存储运输装置内部,达到较好的密封效果。
外罩1和支撑板2的密封连接处指的是外罩1中与支撑板2接触的接触面,以及支撑板2中与外罩1接触的接触面。如图2、图4至图7所示,第一容胶槽3和第二容胶槽4可以均设置在外罩1和支撑板2的密封连接处。如图6至图9所示,第一容胶槽3和第二容胶槽4的形状均可以是方槽、圆槽、梯形槽等,第一容胶槽3的形状与第二容胶槽4的形状可以相同,也可以不同,本申请实施例对此不作限定。第一容胶槽3和第二容胶槽4的槽宽可以设置地相对较宽,以便于增加密封连接处的密封面积,从而提高存储运输装置的密封性,而第一容胶槽3和第二容胶槽4的深度可以设置地较小,使得第一容胶槽3和第二容胶槽4内易于填满密封胶,也可以节省密封胶的使用量。其中,第一容胶槽3的宽度是第一容胶槽3的两个槽壁之间的距离,第二容胶槽4的宽度是第二容胶槽4的两个槽壁之间的距离;第一容胶槽3的深度是第一容胶槽3的槽口至槽底的距离,第二容胶槽4的深度是第二容胶槽4的槽口至槽底的距离。
第一容胶槽3内可以容纳有第一部分密封胶,第二容胶槽4内可以容纳有第二部分密封胶,第一部分密封胶和第二部分密封胶相连接指的是第一部分密封胶与第二部分密封胶相接触。示例地,第一部分密封胶和第二部分密封胶可以直接连接,即第一容胶槽3中的密封胶与第二容胶槽4中的密封胶直接接触。第一部分密封胶和第二密封胶也可以间接连接,这种情况下,第一部分密封胶和第二部分密封胶可以通过外罩1和/或支撑板2的接触面上涂覆的密封胶间接连接,还可以通过从第一容胶槽3溢出的密封胶和/或从第二容胶槽4溢出的密封胶间接连接,本申请实施例对此不作限定。
密封胶可以是任意种类的密封胶。不同种类的密封胶具有不同的透水系数,因此可以根据待运输物对含水量的要求来选择密封胶。例如,待运输物对含水量的要求较高,则可以选择透水系数较小的密封胶;待运输物对含水量的要求较低,则可以选择透水系数较大的密封胶。为了保证该存储运输装置具有良好的密封性,可以在第一容胶槽3和第二容胶槽4均涂满密封胶,且在外罩1的开口端12和支撑板2的其他接触部位均涂覆密封胶。这样,当外罩1和支撑板2盖合时,可以挤压这几部分密封胶,使得密封胶均匀分布在间隙中,通过密封胶填满间隙以起到密封作用。
本申请实施例提供的存储运输装置,将支撑板2盖合于外罩1的开口端12形成容纳待运输物的空间,整个装置中只有外罩1和支撑板2的密封连接处可能存在间隙。本申请在外罩1和支撑板2的密封连接处设置第一容胶槽3和第二容胶槽4,这两个容胶槽中均容纳有密封胶,且这两个容胶槽中的密封胶相连接,也就是说,本申请通过互相连接的密封胶密封外罩1和支撑板2的间隙,有效阻断水汽通路,减少外界环境的水汽进入存储运输装置的可能,从而起到良好的密封效果,以保证该存储运输装置内的湿度不会受到外界环境的影响。本申请并不依赖干燥剂控制存储运输装置内的湿度,因此适用于长时间的干燥存储运输。
在一些实施例中,如图2、图6至图9所示,第一容胶槽3和第二容胶槽4连通。
第一容胶槽3和第二容胶槽4均具有槽口和槽壁。在一些可能的情况下,如图2、图6和图8所示,第一容胶槽3和第二容胶槽4可以直接连通。示例地:参见图2、图6和图8所示,第一容胶槽3的槽口与第二容胶槽4的槽口连通,或者,第一容胶槽3的槽壁与第二容胶槽4的槽壁连通。其中,第一容胶槽3和第二容胶槽4的槽壁均可以设置有通孔,第一容胶槽3和第二容胶槽4通过两者槽壁上的通孔实现第一容胶槽3的槽壁与第二容胶槽4的槽壁连通。
在另一些可能的情况下,如图9所示,第一容胶槽3和第二容胶槽4可以通过外罩1和支撑板2之间的间隙间接连通。
不论第一容胶槽3和第二容胶槽4是哪种方式的连通,第一容胶槽3中的密封胶可以流入第二容胶槽4,第二容胶槽4中的密封胶也可以流入第一容胶槽3。这样,在涂胶时,可以仅向第一容胶槽3涂胶,当第一容胶槽3中的胶填满后可以溢至第二容胶槽4。也可以仅向第二容胶槽4涂胶,当第二容胶槽4中的胶填满后可以溢至第一容胶槽3。当然,也可以同时向第一容胶槽3和第二容胶槽4涂胶,本申请实施例对此不作限定。
第一容胶槽3和第二容胶槽4连通,使得第一容胶槽3中的密封胶和第二容胶槽4中的密封胶可以互相流通。在盖合外罩1与支撑板2时,从第一容胶槽3溢出的密封胶可以流至第二容胶槽4,从第二容胶槽4溢出的密封胶也可以流至第一容胶槽3,便于密封胶存留在外罩1与支撑板2的间隙中,而不至于被挤压至间隙外,从而有利于提高存储运输装置的密封性。
在一些实施例中,如图10和图11所示,第一容胶槽3和第二容胶槽4均沿外罩1的周向设置在外罩1的开口端12。
外罩1的开口端12是外罩1朝向支撑板2的一端,外罩1的开口端12的形状可以是长方形、正方形、圆形等。第一容胶槽3和第二容胶槽4的形状可以与外罩1的开口端12的形状相同也可以不同,本申请实施例对此不做限定。为了保证密封连接处的各个部位均具有良好密封性,外罩1的开口端12沿外罩1的周向可以一整周设置第一容胶槽3和第二容胶槽4,也就是说,第一容胶槽3和第二容胶槽4可以是设置在外罩1的开口端12的环槽。
第二容胶槽4可以位于第一容胶槽3的内侧,也可以位于第一容胶槽3的外侧,本申请实施例对此不作限定。其中,内侧指靠近该存储运输装置内部的一侧,外侧指远离该存储运输内置内部的一侧。
第一容胶槽3和第二容胶槽4可以紧邻设置,或者说,第一容胶槽3和第二容胶槽4可以具有公共的槽壁,这种情况下,第一容胶槽3中的密封胶和第二容胶槽4中的密封胶可以直接连接。第一容胶槽3和第二容胶槽4也可以具有一定间隔,该间隔可以根据外罩1的壁厚来设置,这种情况下,第一容胶槽3中的密封胶和第二容胶槽4中的密封胶可以通过外罩1和/或支撑板2的接触面上涂覆的密封胶间接连接,还可以通过从第一容胶槽3溢出的密封胶和/或从第二容胶槽4溢出的密封胶间接连接。
第一容胶槽3和第二容胶槽4均沿外罩1的周向设置在外罩1的开口端12,提供了一种第一容胶槽3和第二容胶槽4的设置方式。这两个容胶槽中均容纳有密封胶,且这两个容胶槽中的密封胶相连接,相连接的密封胶填充在外罩1和支撑板2的密封连接处的间隙,可以密封该间隙,从而增加外罩1和支撑板2之间的透水路径,有效阻断水汽通路,减少水汽进入的可能,以保证该存储运输装置内的湿度不发生变化。
在一些实施例中,如图2、图4至图9所示,第一容胶槽3和第二容胶槽4均沿外罩1的周向设置在支撑板2上。
第一容胶槽3和第二容胶槽4的形状可以与前面实施例中第一容胶槽3和第二容胶槽4的形状相同。第一容胶槽3和第二容胶槽4的相对位置关系可以与前面实施例中第一容胶槽3和第二容胶槽4的相对位置关系相同。与前面实施例不同的是,本实施例中的第一容胶槽3和第二容胶槽4设置在支撑板2上与外罩1的开口端12接触的部位。
本实施例提供了另一种第一容胶槽3和第二容胶槽4的设置方式。支撑板2的板面较大,在支撑板2上设置第一容胶槽3和第二容胶槽4,可以降低因外罩1的开口端12在密封连接处尺寸有限而较难同时设置第一容胶槽3和第二容胶槽4的风险。
在一些实施例中,如图12至图15所示,第一容胶槽3和第二容胶槽4中的一者沿外罩1的周向设置于外罩1的开口端12,第一容胶槽3和第二容胶槽4中的另一者沿外罩1的周向设置于支撑板2上。
第一容胶槽3和第二容胶槽4的形状可以与前面两个实施例中第一容胶槽3和第二容胶槽4的形状相同。
与前面两个实施例不同的是,本实施例中第一容胶槽3和第二容胶槽4分别位于外罩1的开口端12和支撑板2上。本实施例中,第一容胶槽3和第二容胶槽4的位置可以相对,也可以部分错开,还可以完全错开。
如图12所示,当第一容胶槽3和第二容胶槽4的位置相对时,第一容胶槽3中的密封胶和第二容胶槽4中的密封胶在密封连接处具有第一重叠区域a,第一容胶槽3中的密封胶和第二容胶槽4中的密封胶可以密封第一重叠区域a所在密封连接处的间隙。
如图13所示,当第一容胶槽3和第二容胶槽4部分错开时,第一容胶槽3中的密封胶和第二容胶槽4中的密封胶在密封连接处具有第二重叠区域b、第一错开区域c和第二错开区域d,第一容胶槽3中的密封胶和第二容胶槽4中的密封胶可以密封第二重叠区域b、第一错开区域c和第二错开区域d所在密封连接处的间隙,增大了密封胶密封的范围。其中,第一错开区域c是第一容胶槽3暴露在第二容胶槽4之外的部分,第二错开区域d是第二容胶槽4暴露在第一容胶槽3之外的部分。
如图14所示,当第一容胶槽3和第二容胶槽4完全错开,且第一容胶槽3和第二容胶槽4紧邻设置时,第一容胶槽3中的密封胶和第二容胶槽4中的密封胶直接连接,第一容胶槽3中的密封胶和第二容胶槽4中的密封胶可以密封第一容胶槽3和第二容胶槽4对应的密封连接处的间隙,进一步增大了密封胶密封的范围。
如图15所示,当第一容胶槽3和第二容胶槽4完全错开,且第一容胶槽3和第二容胶槽4间隔设置时,第一容胶槽3中的密封胶和第二容胶槽4中的密封胶通过中间区域e的密封胶间接连接,第一容胶槽3中的密封胶、中间区域e的密封胶和第二容胶槽4中的密封胶可以密封第一容胶槽3、中间区域e、第二容胶槽4对应的密封连接处的间隙,更进一步增大了密封胶密封的范围。其中,中间区域e是密封连接处中位于第一容胶槽3和第二容胶槽4之间的区域,中间区域e的密封胶指外罩1和/或支撑板2的接触面上涂覆的密封胶,或者,从第一容胶槽3溢出的密封胶和/或从第二容胶槽4溢出的密封胶。
本实施例提供了又一种第一容胶槽3和第二容胶槽4的设置方式,将第一容胶槽3和第二容胶槽4分别设置在外罩1的开口端12和支撑板2上,可以降低因外罩1的开口端12或支撑板2在密封连接处尺寸有限而无法同时设置第一容胶槽3和第二容胶槽4的风险,也可以避免将第一容胶槽3和第二容胶槽4集中设置在外罩1或支撑板2上而使外罩1或支撑板2的强度不达标。
在一些实施例中,第二容胶槽4的数量为多个,多个第二容胶槽4错开设置。
不论第一容胶槽3和第二容胶槽4设置在外罩1的开口端12还是支撑板2上,也不论第一容胶槽3和第二容胶槽4的相对位置关系如何,第二容胶槽4的数量均可以为多个。
多个第二容胶槽4错开设置,如果多个第二容胶槽4均涂满密封胶,这多个第二容胶槽4中的密封胶会存留在外罩1和支撑板2的间隙中的不同位置,可以增大密封连接处的密封面积,有利于提高存储运输装置的密封性。
值得指出的是,不论第一容胶槽3和第二容胶槽4的数量是多少,也不论第一容胶槽3和第二容胶槽4设置在外罩1还是支撑板2上,所有第一容胶槽3和第二容胶槽4均可以互相错开。这样,当所有第一容胶槽3和第二容胶槽4填满密封胶,外罩1和支撑板2盖合后,所有第一容胶槽3和第二容胶槽4中的密封胶相连接时,相连接的密封胶可以增加外罩1和支撑板2之间的密封面积,有效阻断水汽通路,减少水汽进入的可能,以保证该存储运输装置内的湿度不发生变化。
在一些实施例中,第二容胶槽4的数量为多个时,可以仅外罩1的开口端12设置有第二容胶槽4。
本实施例中,第一容胶槽3和多个第二容胶槽4可以均位于外罩1的开口端12,或者,第一容胶槽3位于支撑板2上,多个第二容胶槽4均位于外罩1的开口端12。
在一些实施例中,第二容胶槽4的数量为多个时,可以仅支撑板2设置有第二容胶槽4。
本实施例中,第一容胶槽3和多个第二容胶槽4可以均位于支撑板2上,或者,第一容胶槽3位于外罩1的开口端12,多个第二容胶槽4均位于支撑板2上。
在一些实施例中,第二容胶槽4的数量为多个时,外罩1的开口端12和支撑板2均设置有第二容胶槽4。
本实施例中,第一容胶槽3和部分第二容胶槽4可以位于外罩1的开口端12,剩余的第二容胶槽4位于支撑板2上。或者,第一容胶槽3和部分第二容胶槽4可以位于支撑板2上,剩余的第二容胶槽4位于外罩1的开口端12。
前面几个实施例提供了当第二容胶槽4的数量为多个时,第一容胶槽3和多个第二容胶槽4的几种设置方式,设置方式灵活多样。其中,外罩1的开口端12和支撑板2均设置有第二容胶槽4,即第二容胶槽4均设置在外罩1的开口端12和支撑板2上,可以降低因外罩1的开口端12或支撑板2在密封连接处尺寸有限而无法设置多个第二容胶槽4的风险,也可以避免将多个第二容胶槽4集中设置在外罩1或支撑板2上而使外罩1或支撑板2的强度不达标。
在一些实施例中,如图2所示,密封连接处还设置有插接件5,插接件5具有相对的第一端和第二端,第一端与外罩1或支撑板2连接,第二端伸入第一容胶槽3内。
当第一容胶槽3设置在支撑板2上,插接件5设置在外罩1的开口端12与第一容胶槽3相对的位置时,插接件5的第一端与外罩1连接,第二端伸入第一容胶槽3。其中,当外罩1的开口端12上与该第一容胶槽3相对的位置设置有第二容胶槽4时,插接件5可以设置在第二容胶槽4内,当外罩1的开口端12上与该第一容胶槽3相对的位置没有设置第二容胶槽4时,插接件5也可以是设置在外罩1的开口端12未设第二容胶槽4的位置。
当第一容胶槽3设置在外罩1的开口端12,插接件5设置在支撑板2上与第一容胶槽3相对的位置时,插接件5的第一端与支撑板2连接,第二端伸入第一容胶槽3。其中,当支撑板2上与该第一容胶槽3相对的位置设置有第二容胶槽4时,插接件5可以设置在第二容胶槽4内,当支撑板2上与该第一容胶槽3相对的位置没有设置第二容胶槽4时,插接件5也可以是设置在支撑板2上未设第二容胶槽4的位置。
在密封连接处设置插接件5,插接件5的第一端与外罩1或支撑板2连接,当外罩1和支撑板2盖合时,一方面,插接件5的第二端伸入第一容胶槽3内,可以挤压第一容胶槽3内的密封胶,使得第一容胶槽3内的密封胶易于溢至密封连接处,以增加密封连接处的存胶量,从而提高存储运输装置的密封效果。另一方面,插接件5伸入第一容胶槽3,插接件5的侧壁沾满密封胶,外界水汽要绕过插接件5才有可能进入该存储运输装置内,可见,插接件5的设置可以将原本的直线型透水路径改变为曲线型透水路径,增加了密封连接处的透水路径,便于有效阻断水汽通路,减少水汽进入的可能,以保证该存储运输装置内的湿度不发生变化。其中,透水路径指的是外界环境的水汽进入存储运输装置所要经过的路线。
在此需要说明的是,插接件5的第二端伸入第二容胶槽4内,通过挤压第二容胶槽4内的密封胶也可以达到上面的效果。当插接件5的第二端伸入的是外罩1的开口端12的第二容胶槽4时,插接件5可以设置在支撑板2上设置的与该第二容胶槽4相对的第一容胶槽3或第二容胶槽4内,也可以设置在支撑板2上未设第一容胶槽3和第二容胶槽4的位置。当插接件5的第二端伸入的是支撑板2上的第二容胶槽4时,插接件5可以设置在外罩1的开口端12设置的与该第二容胶槽4相对的第一容胶槽3或第二容胶槽4内,也可以设置在外罩1的开口端12未设第一容胶槽3和第二容胶槽4的位置,本申请实施例对此不作限定。
在一些实施例中,如图2所示,插接件5为沿外罩1的周向延伸的环状结构,插接件5连接于外罩1或支撑板2。
基于前面的实施例,插接件5既可以设置在外罩1的开口端12或支撑板2上,也可以设置在第一容胶槽3或第二容胶槽4内,因此,插接件5可以是沿外罩1的周向,从外罩1的开口端12朝支撑板2设置的环状凸起,或者,是从支撑板2朝外罩1设置的环状凸起,或者,是从第一容胶槽3的槽底朝槽口设置的环状凸起,或者,是从第二容胶槽4的槽底朝槽口设置的环状凸起。
将插接件5设置为沿外罩1的周向延伸的环状结构,插接件5的第一端与外罩1或支撑板2连接,第二端伸入第一容胶槽3或第二容胶槽4内,当外罩1和支撑板2盖合时,一方面,插接件5可以沿外罩1的周向在各个位置处挤压第一容胶槽3或第二容胶槽4内的密封胶,使得第一容胶槽3或第二容胶槽4内的密封胶易于溢至密封连接处,可以提高密封胶的密封效果。另一方面,插接件5可以沿外罩1的周向整周伸入第一容胶槽3或第二容胶槽4,沿外罩1的周向整周的外界水汽均要绕过插接件5的第二端才有可能进入存储运输装置内,使得插接件5沿外罩1的周向各个位置均能增加透水路径,便于进一步有效阻断水汽通路,减少水汽进入的可能,以保证该存储运输装置内的湿度不发生变化。
在一些实施例中,如图2所示,当插接件5的第二端伸入第一容胶槽3时,插接件5的第二端与第一容胶槽3的槽底可以具有间距。
如果插接件5的第二端伸入第一容胶槽3后,与第一容胶槽3的槽底接触,也即,插接件5的第二端与第一容胶槽3的槽底没有间距,则插接件5的第二端与槽底互相接触的地方没有密封胶,透水路径会从此处中断,此处将可能有水汽渗入。而如果插接件5的第二端与第一容胶槽3的槽底有间距,则该间距内可以填充密封胶,因而透水路径不会由此中断。因此,有必要在插接件5的第二端与第一容胶槽3的槽底设置间距。
示例地,该间距可以为2mm、5mm等,本申请实施例对此不作限定。但是,在第一容胶槽3的深度不变的情况下,插接件5的第二端插入第一容胶槽3越深,也即,插接件5的第二端与第一容胶槽3的槽底的间距越小,水汽要渗入时需要通过的路程越长,插接件5的设置越能增加透水路径。因此,可以尽可能将间距设置地较小。
插接件5的第二端伸入第一容胶槽3时,插接件5的第二端与第一容胶槽3的槽底具有间距,如此,不会在该间距处将透水路径中断,从而不会影响插接件5发挥提高密封性的效果。
基于前面的描述,插接件5的第二端也可能会伸入第二容胶槽4,该情况下,插接件5的第二端与第二容胶槽4的槽底也可以具有间距,以便很好发挥插接件5的作用。
在一些实施例中,如图2所示,存储运输装置还包括锁紧机构6,锁紧机构6用于锁紧外罩1和支撑板2。
锁紧机构6可以是卡扣,外罩1和支撑板2盖合后,可以通过卡扣将外罩1和支撑板2沿盖合方向锁紧。
锁紧机构6还可以是螺栓和螺母。外罩1的开口端12和支撑板2沿盖合方向可以设置有螺纹孔,外罩1和支撑板2盖合后,可以将螺栓穿过外罩1的开口端12上的螺纹孔和支撑板2上的螺纹孔,将螺母拧紧在螺栓上,以锁紧外罩1和支撑板2。
通过锁紧机构6锁紧外罩1和支撑板2,可以增加外罩1和支撑板2连接的牢靠性,避免运输时外罩1和支撑板2发生连接失效而产生缝隙无法起到密封效果。另外,锁紧机构6锁紧外罩1和支撑板2,可以减小外罩1和支撑板2之间的间隙,从而减小用于密封间隙的密封胶的用量。再者,在锁紧时会挤压第一容胶槽3、第二容胶槽4和密封连接处的密封胶,密封胶在挤压作用下易于较大面积且均匀分布在密封连接处,利于提高密封胶的密封效果。
在一些实施例中,如图10和图11所示,外罩1的开口端12沿周向设置有连接件7,连接件7凸出于外罩1的外壁,连接件7用于连接外罩1和支撑板2,且连接件7与密封胶接触。
连接件7可以是外罩1的开口端12设置的凸出于外罩1的外壁的折边,也可以是连接在外罩1的开口端12的法兰,法兰的外缘凸出于外罩1的外壁。
连接件7朝支撑板2的一侧可以涂抹有密封胶,连接件7上涂抹的密封胶可以与支撑板2上的密封胶接触。
连接件7凸出于外罩1的外壁的部分可以增大外罩1与支撑板2的接触面,从而便于锁紧外罩1和支撑板2,避免运输时外罩1和支撑板2发生连接失效而无法起到密封效果。连接件7与密封胶接触,可以增大外罩1和支撑板2的密封面积,有效阻断水汽通路,减少水汽进入的可能,以保证该存储运输装置内的湿度不发生变化。
根据本申请的一些实施例,参见图1至图11所示,本申请提供了一种存储运输装置,包括外罩1、支撑板2和密封胶。外罩1具有开口11,支撑板2盖合于开口11,以形成容纳待运输物的空间。存储运输装置还包括互相连通的第一容胶槽3和第二容胶槽4,第一容胶槽3和第二容胶槽4位于外罩1和支撑板2的密封连接处且沿外罩1的周向设置于支撑板2上。先向第一容胶槽3和第二容胶槽4内填充密封胶,这两部分密封胶相连接,再将外罩1盖合于支撑板2,通过锁紧机构6锁紧外罩1和支撑板2,以使密封胶均匀分布在间隙中,提高该存储运输装置的密封性。
本领域的技术人员能够理解,尽管在此的一些实施例包括其它实施例中所包括的某些特征而不是其它特征,但是不同实施例的特征的组合意味着处于本申请的范围之内并且形成不同的实施例。例如,在权利要求书中,所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
以上所述,以上实施例仅用以说明本申请的技术方案,而非对其限制;尽管参照前述实施例对本申请进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
