相关技术中,为了对电池进行固定,一般通过电池箱体上的挂载结构对电池箱体进行挂载,那么挂载结构的可靠性也就会影响电池安装可靠性。
发明内容

在一些实施例中,遮挡件的外周侧设有弹性卡扣,挂载梁上形成有卡孔,弹性卡扣插配于卡孔且与挂载梁的表面抵接。
上述技术方案中,通过设置弹性卡扣和卡孔,便于实现遮挡件与挂载梁之间的卡扣连接,方便遮挡件与挂载梁的组装,有利于提升挂载结构的组装效率,同时这种连接方式也不会对挂载梁和遮挡件的电泳工序产生影响。
在一些实施例中,第一连通口形成于挂载梁在长度方向上的端部,卡孔形成在空腔的周侧腔壁上且邻近第一连通口的边沿,遮挡件位于空腔内,弹性卡扣自空腔内通过卡孔伸出空腔外,且与挂载梁的外表面抵接。
上述技术方案中,卡孔与第一连通口的边沿之间的距离较短,或者说,卡孔与挂载梁的形成有第一连通口的长度一端端面之间的距离较短,有利于改善弹性卡扣自空腔内向外穿设于卡孔的过程 中遮挡件与挂载梁之间的干涉、挤压等,便于使得遮挡件通过弹性卡扣顺利安装于挂载梁;同时在一定程度上可以适当增大遮挡件的外轮廓,有利于减小遮挡件外周壁与空腔壁面之间在遮挡件安装后的距离,方便遮挡件与空腔壁面之间直接形成密封、或、方便密封件在遮挡件外周壁与空腔壁面之间可靠密封。
在一些实施例中,弹性卡扣为多个且位于遮挡件的同侧,遮挡件的远离多个弹性卡扣的一侧与空腔的壁面间隔以形成第二连通口的至少部分。
上述技术方案中,通过设置多个弹性卡扣,通过将多个弹性卡扣设于遮挡件的同侧,且遮挡件的远离多个弹性卡扣的一侧与空腔的壁面间隔开,便于遮挡件沿相对于卡孔的中心轴线倾斜的设定方向顺利安装于空腔,有利于改善遮挡件安装过程中弹性卡扣与遮挡件的远离弹性卡扣的一侧之间发生装配干涉,提升遮挡件的安装便利性。
在一些实施例中,遮挡件的外周壁除连接弹性卡扣的部分外,其余部分与空腔的壁面间隔设置以在空腔的壁面与遮挡件之间形成第二连通口。
上述技术方案中,通过设置遮挡件的外周壁除连接弹性卡扣的部分外,其余部分与空腔的壁面间隔设置,便于实现遮挡件的可靠、稳定安装,提升遮挡件对电泳液冲击的承载能力,同时可以适当增大第二连通口的第一连通口面积,提升电泳液在进出空腔时的流通面积,有利于提升电泳效率。
在一些实施例中,遮挡件外周侧的第二连通口的宽度沿环绕遮挡件的方向不变。
上述技术方案中,通过设置遮挡件外周侧的第二连通口的宽度沿环绕遮挡件的方向不变,则密封该第二连通口的密封件的宽度可以为定值,有利于简化密封件的结构;尤其是当密封件采用发泡材料件时,通常发泡材料件的发泡比例是一定的,上述设置便于通过等厚度的发泡材料来密封第二连通口,便于简化密封件的设计。
在一些实施例中,弹性卡扣包括主体部和弹性臂部,主体部与遮挡件相连,且穿设于卡孔,弹性臂部悬臂设置于主体部的远离遮挡件的一端,弹性臂部的自由端与主体部之间限定出大小可调的开口,弹性臂部的背离主体部的一侧表面形成有朝向主体部凹陷的凹槽,凹槽贯穿弹性臂部的自由端,以使弹性臂部与挂载梁的表面、卡孔的孔壁分别抵接。
上述技术方案中,通过设置弹性臂部的自由端与主体部之间限定出大小可调的开口,以便利用弹性卡扣的弹性变形能力实现遮挡件的快速、顺利、可靠安装;通过在弹性臂部的远离主体部的一侧表面形成有凹槽,以使弹性臂部与挂载梁的表面、卡孔的孔壁分别抵接,以在实现遮挡件顺利、可靠安装的前提下,使得遮挡件安装完整后弹性臂部的一部分配合在卡孔内且与卡孔的孔壁抵接,以便在遮挡件需要拆卸时,可以直接挤压弹性臂部直至弹性臂部与挂载梁的表面脱离配合即可,无需将弹性臂部的自由端与卡孔对准,方便遮挡件拆卸。
在一些实施例中,遮挡件包括板体部和连接部,连接部设于板体部且参与限定第二连通口,密封件连接于连接部的背离板体部的一侧,在板体部的厚度方向上,连接部的厚度大于板体部的厚度。
上述技术方案中,通过设置遮挡件包括板体部和连接部,可以使得遮挡件大致呈板状结构,便于实现对第一连通口的部分的可靠遮挡,而连接部将板体部与密封件隔开,并使得连接部的厚度大于板体部的厚度,便于为密封件提供较大的设置区域,提升密封件与遮挡件的连接面积,实现密封件与遮挡件的可靠连接。
在一些实施例中,其中一个连接部为第一连接部,第一连接部设于板体部的外周侧,第一连接部的背离板体部的一侧表面与空腔的壁面之间限定出第二连通口;和/或,其中一个连接部为第二连接部,第二连接部呈环形,板体部设于第二连接部的外周侧,第二连接部的背离板体部的一侧表面限定出第二连通口。

上述技术方案中,通过设置挂载梁为一体件,便于挂载梁的加工,同时第一腔部的厚度大于第二腔部的厚度,使得空腔的腔壁在第一腔部和第二腔部的连接位置处并非平整设置,则该连接位置可以对对应腔壁起到一定的加强作用,有利于提升挂载梁的结构强度和结构稳定性;此外,当挂载结构用于电池箱体中时,挂载梁与箱体本体连接,且第一腔部的敞开侧朝向箱体本体设置,由于第一腔部的厚度大于第二腔部的厚度,以便提升挂载梁与箱体本体的连接可靠性。
在一些实施例中,遮挡件为树脂件、或金属件,密封件为发泡材料件。
上述技术方案中,遮挡件具有良好的结构强度,且密封件能可靠密封第二连通口;而且,当发泡材料件构造成通过高温方式发泡时,可以利用电泳工序中的烘烤来同时实现发泡,简化加工工序,提升加工效率。

在一些实施例中,支撑件设于遮挡件与挂载梁的连接位置处。
上述技术方案中,通过将支撑件设于遮挡件与挂载梁的连接位置处,有利于进一步减小遮挡件与挂载梁连接位置处的受力,例如遮挡件通过弹性卡扣卡设于挂载梁,支撑件的设置有利于改善弹性卡扣的受力,便于提升遮挡件安装可靠性。

近些年,新能源汽车有了飞跃式的发展,在电动汽车领域,电池作为电动汽车的动力源,起着不可替代的重要作用。其中,电池在安装可靠性方面有着较高的要求。
相关技术中,为了对电池进行固定,一般通过电池箱体上的挂载结构对电池箱体进行挂载,那么挂载结构的可靠性也就会影响电池安装可靠性。
基于上述考虑,提出了一种挂载结构,包括挂载梁、遮挡件和密封件,挂载梁内限定出空腔,挂载梁还形成有连通空腔内外两侧的第一连通口,挂载梁上至少空腔的壁面设有电泳层,遮挡件与挂载梁相连且遮挡第一连通口的一部分,遮挡件的表面也设有电泳层,空腔的壁面与遮挡件之间和/或遮挡件上形成有与空腔连通的第二连通口,密封件密封第二连通口。

请参照图1,图1为本申请一些实施例提供的用电装置1000为车辆的结构示意图。车辆可以为燃油汽车、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。车辆设置有电池200,电池200可以设置在车辆的底部或头部或尾部。电池200可以用于车辆的供电,例如,电池200可以作为车辆的操作电源。车辆还可以包括控制器300和马达400,控制器300用来控制电池200为马达400供电,例如,用于车辆的启动、导航和行驶时的工作用电需求。在本申请一些实施例中,电池200不仅可以作为车辆的操作电源,还可以作为车辆的驱动电源,代替或部分地代替燃油或天然气为车辆提供驱动动力。
请参照图2,图2为本申请一些实施例提供的电池200的结构爆炸图。电池200包括电池箱体100和多个电池单体101,电池单体101容纳于电池箱体100内。其中,电池箱体100用于为电池单体101提供装配空间,电池箱体100可以采用多种结构。在一些实施例中,电池箱体100可以包括箱体本体2,箱体本体2包括第一箱体1001和第二箱体1002,第一箱体1001与第二箱体1002相互盖合,第一箱体1001和第二箱体1002共同限定出用于容纳电池单体101的容纳腔2a。第二箱体1002可以为一端开放的空心结构,第一箱体1001可以为板状结构,第一箱体1001盖合于第二箱体1002的开放侧,以使第一箱体1001与第二箱体1002共同限定出容纳腔2a;或者,第一箱体1001和第二箱体1002还可以均为一侧开放的空心结构(例如图2所示),第一箱体1001的开放侧盖合于第二箱体1002的开放侧。当然,第一箱体1001和第二箱体1002形成的电池箱体100可以是多种形状,比如,圆柱体或长方体等。
在电池200中,多个电池单体101之间可串联、并联或混联,混联是指多个电池单体101中既有串联又有并联。多个电池单体101之间可直接串联、并联或混联在一起,再将多个电池单体101构成的整体容纳于电池箱体100内;或者,电池200也可以是多个电池单体101先串联、并联或混联组成电池模组形式,多个电池模组再串联、并联或混联形成一个整体,并容纳于电池箱体100内。 电池200还可以包括其他结构,例如,电池200还可以包括汇流排,用于实现多个电池单体101之间的电连接。
请参照图3和图4,在本申请的实施例中,挂载结构1可以实现相关结构的固定、挂载,例如挂载结构1用于电池200中,可以实现支撑、固定电池200。
挂载结构1包括挂载梁11,挂载梁11可以提供合适数量以及合适布置方式的挂载点位,挂载梁11内限定出空腔11a,挂载梁11的至少部分可以大致呈中空结构,便于通过较少的材料量实现挂载梁11足够的结构强度和稳定性,有利于提升挂载结构1的使用可靠性;其中,挂载梁11上形成有连通空腔11a内外两侧的第一连通口11d,挂载梁11上至少空腔11a的壁面设有电泳层,则在电泳过程中,电泳液可以通过第一连通口11d流至空腔11a内、或自空腔11a内流出,以在空腔11a壁面上形成电泳层,有利于提升空腔11a壁面的防腐性能等,从而提升挂载梁11的使用可靠性。当然,挂载梁11的外表面(例如挂载梁11的背向空腔11a的表面)可以并未设置电泳层、或挂载梁11的外表面也设有电泳层。
挂载结构1还包括遮挡件12,遮挡件12与挂载梁11相连,且遮挡件12遮挡第一连通口11d的一部分,遮挡件12的表面也设有电泳层,空腔11a的壁面与遮挡件12之间形成有与空腔11a连通的第二连通口12a、和/或、遮挡件12上形成有与空腔11a连通的第二连通口12a,第二连通口12a与第一连通口11d相对且连通;示例性地,遮挡件12表面的电泳层和空腔11a壁面上的电泳层可以在同一电泳工序中形成,则在电泳前中,遮挡件12设于第一连通口11d处以遮挡第一连通口11d的一部分,电泳时,电泳液可以通过第二连通口12a流至空腔11a内、或自空腔11a内流出,实现空腔11a壁面的顺利电泳。挂载结构1还包括密封件13,密封件13密封第二连通口12a,则遮挡件12和密封件13可以实现第一连通口11d处的密封设置,以便封闭空腔11a,挂载结构1运输、或使用时,外界杂物或水等不易通过第一连通口11d进入空腔11a内造成腐蚀问题等,以便进一步提升挂载梁1的使用可靠性。
可以理解的是,第二连通口12a可以为一个或多个;当第二连通口12a为多个时,每个第二连通口12a处分别对应一个密封件13、或、一个密封件13密封所有第二连通口12a,但不限于此。遮挡件12与挂载梁11的相对位置本申请实施例不做具体限制。
例如,以第一连通口11d形成于挂载梁11的长度端部为例:
遮挡件12可以与挂载梁11的长度方向(例如图3中的X方向)上的端面抵接,此时遮挡件12的至少部分可以位于空腔11a外,在挂载梁11的横截面上,遮挡件12的正投影的一部分位于空腔11a壁面的正投影外轮廓内、另一部分位于空腔11a壁面的正投影外轮廓外,挂载梁11的横截面垂直于挂载梁11的长度方向,可以包括以下方案:1、空腔11a的壁面与遮挡件12之间形成有第二连通口12a,则在挂载梁11的横截面上,遮挡件12的正投影外边缘的一部分位于空腔11a壁面的正投影外轮廓内、另一部分位于空腔11a壁面的正投影外轮廓外;2、遮挡件12上形成有第二连通口12a,第二连通口12a可以与第一连通口11d相对,在挂载梁11的横截面上,遮挡件12的正投影的整个外边缘位于空腔11a壁面的正投影外轮廓外;3、遮挡件12上形成有第二连通口12a,且空腔11a的壁面与遮挡件12之间也形成有第二连通口12a。
或者,遮挡件12设于空腔11a内且邻近第一连通口11d设置,此时在挂载梁11的横截面上, 遮挡件12的正投影位于空腔11a壁面的正投影外轮廓内,可以包括以下方案:1、空腔11a的壁面与遮挡件12之间形成有第二连通口12a,则遮挡件12的外周壁的至少部分与空腔11a壁面间隔开设置,以限定出第二连通口12a;2、遮挡件12上形成有第二连通口12a,第二连通口12a可以与第一连通口11d相对,遮挡件12的外周壁可以与空腔11a的壁面抵接;3、遮挡件12上形成有第二连通口12a,且空腔11a的壁面与遮挡件12之间也形成有第二连通口12a。
当然,第一连通口11d还可以形成在挂载梁11的侧壁上,比如第一连通口11d形成于挂载梁11在其宽度方向(例如图3中的Y方向)上的侧壁上、或、第一连通口11d形成于挂载梁11在其厚度方向(例如图3中的Z方向)上的侧壁上,本申请不再赘述。
可见,上述技术方案中,对于空腔11a而言,遮挡件12与密封件13配合提升空腔11a在第一连通口11d处的密封性,同时加上电泳层的设置,便于双重提升空腔11a壁面的防腐性能,从而提升挂载结构1的使用可靠性;而且,遮挡件12和密封件13的设置,也不会影响空腔11a的电泳工序,且有利于减小密封件13需要密封的区域大小,便于实现密封件13对第二连通口12a的可靠密封,有利于提升遮挡件12和密封件13对第一连通口11d处的密封效果。
相对于一些技术中,为了提升挂载梁的使用可靠性,通常在挂载梁的第一连通口处设置一个钣金件直接封堵第一连通口,以阻挡外界杂物等进入空腔内,从而提升耐腐性能,而钣金件与挂载梁弧焊连接,则如果挂载梁在进行电泳前,将钣金件与挂载梁焊接固定,钣金件封堵第一连通口导致电泳液无法流至空腔内,难以实现空腔壁面的正常电泳,未设置电泳层或电泳层质量较差,影响挂载梁的耐腐性能和可靠性,如果先对挂载梁进行电泳、再将钣金件与挂载梁焊接,电泳层会影响钣金件与挂载梁之间的焊接质量,难以实现钣金件与挂载梁之间的可靠焊接,易导致钣金件无法可靠密封第一连通口处,易降低挂载梁的耐腐性能和可靠性。
本申请上述设置,可以解决相关技术中“钣金件与挂载梁焊接相连”与“挂载梁电泳”之间的矛盾,提升加工便利性;例如在挂载梁11进行电泳操作之前,将遮挡件12安装于挂载梁11,电泳液能通过第二连通口12a正常流至空腔11a内、或自空腔11a内流出,而后再将密封件13密封在第二连通口12a,以便封闭空腔11a。
可以理解的是,密封件13可以在完成电泳后将第二连通口12a密封,或者,密封件13具有第一状态和第二状态,密封件13在第一状态下的体积小于在第二状态下的体积,在第二状态,密封件13能密封第二连通口12a,在第一状态,密封件13无法密封连通,则在电泳前,可以将处于第一状态的密封件13安装至第二连通口12a处,在电泳液自空腔11a内流出后的后续工序中,触发密封件13以使密封件13切换至第二状态以密封第二连通口12a。
此外,密封件13密封第二连通口12a的方式本申请不做具体限制,比如密封件13粘接于第二连通口12a的周壁、或密封件13粘接于遮挡件12且封堵第二连通口12a、或密封件13过盈配合于第二连通口12a等等。
请参考图6和图7,在一些实施例中,遮挡件12的外周侧设有弹性卡扣14,挂载梁11上形成有卡孔11e,弹性卡扣14插配于卡孔11e,且弹性卡扣14与挂载梁11的表面抵接,以便实现遮挡件12与挂载梁11之间的卡扣连接,方便遮挡件12与挂载梁11的组装,有利于提升挂载结构1的组装效率,同时这种连接方式也不会对挂载梁11和遮挡件12的电泳工序产生影响。
示例性地,如图4、图6和图7所示,挂载结构1构造成:弹性卡扣14适于自卡孔11e的内侧朝向卡孔11e的外侧插配于卡孔11e,且弹性卡扣14与挂载梁11的外表面抵接。当然,在其他示例中,挂载结构1还可以构造成:弹性卡扣14适于自卡孔11e的外侧朝向卡孔11e的内侧插配于卡孔11e,且弹性卡扣14与挂载梁11的内表面(即空腔11a的壁面)抵接。本申请描述中,卡孔11e的外侧可以理解为卡孔11e的背向空腔11a的一侧,卡孔11e的内侧可以理解为卡孔11e的朝向空腔11a的一侧。
当然,在本申请其他实施例中,遮挡件12与挂载梁11之间的连接方式还可以为粘接固定、螺纹连接等,也不会对电泳工序产生影响。
请参考图4、图6和图7,在一些实施例中,遮挡件12位于空腔11a内,弹性卡扣14自空腔11a内通过卡孔11e伸出空腔11a外,且弹性卡扣14与挂载梁11的外表面抵接。
上述技术方案中,通过将遮挡件12设于空腔11a内,弹性卡扣14自空腔11a内通过卡孔11e伸出空腔11a外以与挂载梁11的外表面抵接,可以使得挂载梁11对遮挡件12起到一定保护作用,例如可以减少遮挡件12受到的碰撞等,有利于减小弹性卡扣14受到的外力,同时配合弹性卡扣14的上述设置,便于在实现遮挡件12通过弹性卡扣14可靠安装于挂载梁11的前提下,有利于简化遮挡件12与弹性卡扣14之间的连接设置。
请参考图4、图6和图7,在一些实施例中,遮挡件12位于空腔11a内,弹性卡扣14自空腔11a内通过卡孔11e伸出空腔11a外,且弹性卡扣14与挂载梁11的外表面抵接;第一连通口11d形成于挂载梁11在长度方向上的端部,卡孔11e形成在空腔11a的周侧腔壁上,且卡孔11e邻近第一连通口11d的边沿。
例如,空腔11a的周侧腔壁包括挂载梁11在其宽度方向上的两侧侧壁、以及挂载梁11在其厚度方向上的两侧侧壁。
可见,上述技术方案中,卡孔11e与第一连通口11d的边沿之间的距离较短,或者说,卡孔11e与挂载梁11的形成有第一连通口11d的长度一端端面之间的距离较短,有利于改善弹性卡扣14自空腔11a内向外穿设于卡孔11e的过程中遮挡件12与挂载梁11之间的干涉、挤压等,便于使得遮挡件12通过弹性卡扣14顺利安装于挂载梁11;同时在一定程度上可以适当增大遮挡件12的外轮廓,有利于减小遮挡件12外周壁与空腔11a壁面之间在遮挡件12安装后的距离,方便遮挡件12与空腔11a壁面之间直接形成密封、或、方便密封件13在遮挡件12外周壁与空腔11a壁面之间可靠密封。
请参考图6和图8,在一些实施例中,弹性卡扣14为多个,多个弹性卡扣14位于遮挡件12的同侧,遮挡件12的远离多个弹性卡扣14的一侧与空腔11a的壁面间隔以形成第二连通口12a的至少部分。
上述技术方案中,通过设置多个弹性卡扣14,通过将多个弹性卡扣14设于遮挡件12的同侧,且遮挡件12的远离多个弹性卡扣14的一侧与空腔11a的壁面间隔开,便于遮挡件12沿相对于卡孔11e的中心轴线倾斜的设定方向顺利安装于空腔11a,有利于改善遮挡件12安装过程中弹性卡扣14与遮挡件12的远离弹性卡扣14的一侧之间发生装配干涉,提升遮挡件12的安装便利性。
示例性地,遮挡件12的外轮廓大致呈多边形,多个弹性卡扣14对应于上述多边形的同一条边 设置,上述多边形的与多个弹性卡扣14相对的一条边与空腔11a的壁面间隔开,上述多边形中,除设置弹性卡扣14的边、以及与多个弹性卡扣14相对的边外,其余边与空腔11a的壁面可以间隔设置、也可以止抵设置。结合图6和图8,以遮挡件12的外轮廓大致呈四边形为例,四条边分别为首尾依次连接的第一边、第二边、第三边和第四边,多个弹性卡扣14设于第一边,第三边与空腔11a的壁面间隔开,而第二边和第四边可以设置为:1、第二边和第四边分别与空腔11a的壁面止抵,此时第三边与空腔11a的壁面之间形成第二连通口12a;2、第二边和第四边分别与空腔11a的壁面间隔开(如图6所示),此时第二边、第三边和第四边三者与空腔11a的壁面之间形成第二连通口12a的至少部分;3、第二边和第四边中的其中一个与空腔11a的壁面止抵,另一个与空腔11a的壁面间隔开。
当然,在本申请其他实施例中,弹性卡扣14还可以为一个。
请参考图6,在一些实施例中,遮挡件12的外周壁除连接弹性卡扣14的部分外,其余部分与空腔11a的壁面间隔设置以在空腔11a的壁面与遮挡件12之间形成第二连通口12a,则遮挡件12的外周壁的连接弹性卡扣14的部分可以与空腔11a的壁面抵接,而弹性卡扣14与挂载梁11的外表面抵接,便于实现遮挡件12和弹性卡扣14分别夹持于空腔11a的腔壁的厚度两侧,实现遮挡件12的可靠安装。
上述技术方案中,通过设置遮挡件12的外周壁除连接弹性卡扣14的部分外,其余部分与空腔11a的壁面间隔设置,便于实现遮挡件12的可靠、稳定安装,提升遮挡件12对电泳液冲击的承载能力,同时可以适当增大第二连通口12a的第一连通口11d面积,提升电泳液在进出空腔11a时的流通面积,有利于提升电泳效率。
请参考图6,在一些实施例中,遮挡件12外周侧的第二连通口12a的宽度d沿环绕遮挡件12的方向不变,则在环绕遮挡件12的方向上,第二连通口12a的宽度d为定值;可见,遮挡件12的外周壁除链接弹性卡扣14的部分外,其余部分与空腔11a的壁面之间的间距相等。
上述技术方案中,通过设置遮挡件12外周侧的第二连通口12a的宽度d沿环绕遮挡件12的方向不变,则密封该第二连通口12a的密封件13的宽度可以为定值,有利于简化密封件13的结构;尤其是当密封件13采用发泡材料件时,通常发泡材料件的发泡比例是一定的,上述设置便于通过等厚度的发泡材料来密封第二连通口12a,便于简化密封件13的设计。
示例性地,遮挡件12外周侧的第二连通口12a的宽度d可以为3mm,但不限于,宽度d还可以为2mm、4mm、5mm等等。

可见,弹性臂部142在外力作用下发生变形,使得弹性臂部142的自由端与主体部141之间的距离发生变化,从而调节开口14a的大小;则遮挡件12安装时,弹性卡扣14在穿设卡孔11e过程中,弹性卡扣14在卡孔11e的孔壁的挤压下,弹性臂部142朝向靠近主体部141的方向变形,使得开口14a的尺寸减小,随着弹性卡扣14的逐渐穿设,弹性臂部142始终具有恢复至初始形态的 趋势,直至弹性臂部142的至少部分在卡孔11e的径向上伸出卡孔11e以使弹性臂部142能抵接于挂载梁11的围绕卡孔11e的部分,实现遮挡件12的可靠安装。
上述技术方案中,通过设置弹性臂部142的自由端与主体部141之间限定出大小可调的开口14a,以便利用弹性卡扣14的弹性变形能力实现遮挡件12的快速、顺利、可靠安装。

例如,如图6、图8-图10所示,弹性臂部142的背离主体部141的一侧表面形成有朝向主体部141凹陷的凹槽142a,凹槽142a贯穿弹性臂部142的自由端,则凹槽142a的背向主体部141的一侧敞开设置,且凹槽142a的背向弹性臂部142的悬臂端的一侧也敞开设置,以使弹性臂部142与挂载梁11的表面、卡孔11e的孔壁分别抵接。
可见,弹性卡扣14卡设于卡孔11e以实现遮挡件12的安装后,弹性臂部142的一部分伸出卡孔11e外,且弹性臂部142的伸出卡孔11e外的部分与挂载梁11的表面抵接,弹性臂部142的还有一部分位于卡孔11e内,且弹性臂部142的位于卡孔11e内的部分与卡孔11e的孔壁抵接。

示例性地,如图6、图8和图12所示,以弹性卡扣14与挂载梁11的外表面抵接为例,在卡孔11e的周向上,凹槽142a也贯穿弹性臂部142的两端,此时凹槽142a可以具有第一槽壁142b和第二槽壁142c,第一槽壁142b可以与挂载梁11的围绕卡孔11e的部分外表面平行,第二槽壁142c连接在第一槽壁142b的内侧边沿;换言之,弹性臂部142可以包括第一部分1421和第二部分1422,第一部分1421的一端连接于主体部141,第一部分1421的另一端端面的一部分形成第一槽壁142b,另一部分连接于第二部分1422,第二部分1422的远离第一部分1421的一端形成弹性臂部142的自由端,第二部分1422的背离主体部141的一侧表面形成第二槽壁142c。弹性卡扣14卡设于挂载梁11时,第一部分1421位于卡孔11e外,且第一槽壁142b与挂载梁11的外表面抵接,第二部分1422位于卡孔11e内,且第二槽壁142c与卡孔11e的孔壁抵接。

上述技术方案中,通过设置遮挡件12包括板体部121和连接部122,可以使得遮挡件12大致呈板状结构,便于实现对第一连通口11d的部分的可靠遮挡,而连接部122将板体部121与密封件 13隔开,并使得连接部122的厚度大于板体部121的厚度,便于为密封件13提供较大的设置区域,提升密封件13与遮挡件12的连接面积,实现密封件13与遮挡件12的可靠连接。
可以理解的是,板体部121的厚度方向与第一连通口11d的轴向平行,或,板体部121的厚度方向与第一连通口11d的轴向呈夹角设置。当第一连通口11d形成在挂载梁11的长度方向上的一端时,第一连通口11d的轴向可以与挂载梁11的长度方向平行,或,第一连通口11d的轴向可以与挂载梁11的长度方向呈夹角布置;示例性地,结合图3和图5,挂载梁11的长度方向上的两端分别形成有第一连通口11d,挂载梁11长度方向上的其中一端的端面与长度方向垂直,上述其中一端对应的第一连通口11d的轴向与长度方向平行,挂载梁11长度方向上的另一端的端面与长度方向呈锐角夹角,上述另一端对应的第一连通口11d的轴向与长度方向呈夹角设置。

此外,当空腔11a的壁面与遮挡件12之间形成有第二连通口12a时,与该第二连通口12a对应的连接部122设于板体部121的外周侧;当遮挡件12上形成有第二连通口12a时,与该第二连通口12a对应的连接部122呈环形,且板体部121连接于该连接部122的外周侧。
请参考图6、图8和图10,在一些实施例中,其中一个连接部122为第一连接部1221,第一连接部1221设于板体部121的外周侧,第一连接部1221的背离板体部121的一侧表面与空腔11a的壁面之间限定出第二连通口12a,该第二连通口12a位于空腔11a的壁面与遮挡件12之间;和/或,其中一个连接部122为第二连接部1222,第二连接部1222呈环形,板体部121设于第二连接部1222的外周侧,第二连接部1222的背离板体部121的一侧表面限定出第二连通口12a,该第二连通口12a形成在遮挡件12上。

示例性地,当遮挡件12通过弹性卡扣14安装于挂载梁11时,弹性卡扣14可以设在第一连接部1221上;例如,第一连接部1221的背离板体部121的一侧表面除连接弹性卡扣14的部分外,其余部分与空腔11a的壁面间隔以形成第二连通口12a。
可以理解的是,本申请实施例中,第二连接部1222的数量、形状以及布置方式可以根据空腔11a形状以及实际需求等具体设置。示例性地,如图4和图10所示,第二连接部1222为三个,其中两个第二连接部1222的长度方向与挂载梁11的厚度方向平行,其余第二连接部1222的长度方向与挂载梁11的宽度方向平行。
请参考图7,在一些实施例中,挂载梁11为一体件,空腔11a包括沿挂载梁11宽度方向依次设置的第一腔部11b和第二腔部11c,在挂载梁11的厚度方向上,第一腔部11b的厚度t1大于第二腔部11c的厚度t2,且第一腔部11b的背离第二腔部11c的一侧敞开设置。
上述技术方案中,通过设置挂载梁11为一体件,便于挂载梁11的加工,同时第一腔部11b的厚度大于第二腔部11c的厚度,使得空腔11a的腔壁在第一腔部11b和第二腔部11c的连接位置处并非平整设置,则该连接位置可以对对应腔壁起到一定的加强作用,有利于提升挂载梁11的结构 强度和结构稳定性;此外,当挂载结构1用于电池箱体100中时,挂载梁11与箱体本体2连接,且第一腔部11b的敞开侧朝向箱体本体2设置,由于第一腔部11b的厚度大于第二腔部11c的厚度,以便提升挂载梁11与箱体本体2的连接可靠性。

可以理解的是,第一遮挡部123上第二连通口12a的数量、布置方式以及第二遮挡部124上第二连通口12a的数量、布置方式等可以根据实际需求具体设置。示例性地,第一遮挡部123和第二遮挡部124上的第二连通口12a的宽度可以为5mm,但不限于此。
在一些实施例中,遮挡件12为树脂件、或金属件,密封件13为发泡材料件。由此,遮挡件12具有良好的结构强度,且密封件13能可靠密封第二连通口12a;而且,当发泡材料件构造成通过高温方式发泡时,可以利用电泳工序中的烘烤来同时实现发泡,简化加工工序,提升加工效率。其中,烘烤工序中烘烤温度和烘烤时间可以根据实际需求设置,烘烤温度可以为200℃,烘烤时间为20min。
结合图6、图8-图10,示出的密封件13为发泡前的状态,遮挡件12和发泡前的密封件13可以构成夹胶件,将该夹胶件安装于挂载梁11后进行电泳,待电泳液自空腔11a排出后,需要进行烘烤,以使电泳液干燥形成电泳层,同时在烘烤工序中,密封件13发泡膨胀,以密封第二连通口12a;可见,利用电泳工序中的烘烤工序,既实现了电泳,同时实现了密封件13的发泡。
可以理解的是,发泡材料件的发泡倍数可以根据实际需求具体设置,例如发泡倍数为9倍,发泡倍数可以理解为发泡后体积与发泡前体积之比。
请参考图10-图13,在一些实施例中,在第二连通口12a的轴向上,遮挡件12的相对两侧分别设有支撑件15,支撑件15设于遮挡件12的外周侧,且支撑件15与空腔11a的壁面抵接。
示例性地,遮挡件12设于空腔11a内,电泳液大致沿第二连通口12a的轴向或沿与第二连通口12a轴向倾斜的方向进出空腔11a,则电泳液对遮挡件12的冲击力大致沿第二连通口12a的轴向或具有沿第二连通口12a轴向的分力,那么遮挡件12在第二连通口12a轴向上的两侧分别设置支撑件15,而支撑件15与空腔11a的壁面抵接,以提升遮挡件12对电泳液冲击的承载能力。
上述技术方案中,通过在遮挡件12的相对两侧分别设置支撑件15,支撑件15与空腔11a的壁面抵接,有利于提升遮挡件12的安装稳定性,提升遮挡件12对电泳液冲击的承载能力,降低遮挡 件12被电泳液冲击倾倒的风险,同时有利于减小遮挡件12与挂载梁11连接位置处的受力,提升安装可靠性。
