目前,从市场形势的发展来看,电池的应用越加广泛。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。
在一些用电装置中,采用电池进行供电,电池包括电池箱体、设于电池箱体内的电池单体和设于电池箱体的锁附结构,电池通过锁附结构安装于用电装置上。以车辆为例,电池可以通过锁附结构安装于车辆的车底纵梁上,以利用车体下方有限的安装空间来安装电池,并且便于对车辆电池的换电和维修等操作。
在相关技术中,锁附结构主要采用焊接或螺栓固定的结构形式与电池箱体连接,电池箱体上焊接处和螺栓锁附处容易变形、开裂,导致强度很难保证。为了满足焊接和螺栓固定的强度需求,在电池箱体上与锁附结构连接位置需要加厚,导致电池箱体的箱壁厚度增大,占用电池的内部空间,进而导致降低电池箱体内电池单体的可占用空间,从而降低空间利用率、降低电池能量密度和续航能力,或者导致电池的整体体积增大,不利于部分车体下方较小安装空间的安装需求,且容易导致电池的离地高度过小。并且,焊接强度和螺栓固定强度也有限,对于一些对强度要求较高的电池,很难满足其结构强度需求。
基于此,本申请提出了一种电池箱体100,包括挂载板10和挂载件20。挂载板10和具有安装槽101,安装槽101具有朝向第一方向F1的开口102。挂载件20包括底座部21和沿第一方向F1凸出于底座部21的凸出部22,底座部21的至少部分嵌于安装槽101中,凸出部22的至少部分沿第一方向F1经由开口102伸出安装槽101外。
在上述这种结构的电池箱体100中,挂载件20和挂载板10采用嵌入挂载式连接,以形成挂载件20与挂载板10之间的互锁连接,提升结构可靠性和强度。并且,嵌入挂载式连接方式对挂载板10的厚度要求较低,可以降低占用电池箱体100内部的空间,以使具有电池箱体100的电池1000能够有更大的空间安装电池单体,有利于提高电池1000的空间利用率、能量密度和续航能力。并且,有利于减小电池箱体100的整体占用空间,进而减小电池1000的整体占用空间,例如在电池1000安装于车体下方时,有利于增大电池1000的离地高度,且有利于满足车体下方安装空间较小的车型安装需求。
采用本申请实施例公开的电池箱体100的电池1000可以用于、但不限用于车辆、船舶或飞行器等用电装置2000中,可以使具备本申请公开的电池1000等组成该用电装
置2000的电源系统,以提高用电装置2000的使用安全性和可靠性。
例如,本申请实施例公开的用电装置2000可以是、但不限于是车辆、轮船、航天器、电动玩具和电动工具等等。车辆可以是燃油车辆、或燃气车辆、或新能源车辆、或轨道车辆,新能源车辆可以是纯电动车辆、混合动力车辆或增程式车辆等;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、电动车辆玩具、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。
下面,参考附图,描述根据本申请实施例的电池箱体100。
请参照图1-图5,图1为本申请一些实施例提供的电池箱体100的爆炸图,图2为图1中圈示A处的放大结构示意图,图3为本申请一些实施例提供的电池箱体100的俯视图,图4为图3沿B-B线所示方向的剖视图,图5为图4中圈示C处的放大结构示意图。电池箱体100包括挂载板10和挂载件20。挂载板10具有安装槽101,安装槽101具有朝向第一方向F1的开口102。挂载件20包括底座部21和沿第一方向F1凸出于底座部21的凸出部22,底座部21的至少部分嵌于安装槽101中,凸出部22的至少部分沿第一方向F1经由开口102伸出安装槽101外。
请参照图1和图2,挂载板10,指能够实现挂载功能的板体,板体可以为实心板也可以为空心板。挂载板10可以自身形成为电池箱体100的箱壁,以减小电池箱体100的占用空间;或者挂载板10可以为安装于电池箱体100的箱壁的板体,以利于提高电池箱体100的强度。
例如在如图1所示的示例中,电池箱体100的箱壁包括多个侧壁、顶壁和箱底壁30,多个侧壁构成两个第一侧壁33、两个第二侧壁34和两个凹部侧壁31,顶壁包括凹部底壁32。其中,两个相对的凹部侧壁31形成为挂载板10,并且两个挂载板10上均设有挂载件20,以使挂载板10与其他侧壁、顶壁和箱底壁30配合限定出电池箱体100的用于安装电池单体的安装腔。
安装槽101具有朝向第一方向F1的开口102,即开口102沿第一方向F1贯穿安装槽101的槽壁,以使安装槽101内空间通过开口102与外部空间连通。
请参照图2和图5,挂载件20,指能够挂载于挂载板10的部件。具体地,挂载件20包括底座部21和沿第一方向F1凸出于底座部21的凸出部22。底座部21可以为板体、块体或者其他不规则形状等。凸出部22可以为板体、块体、柱体、钩体或其他不规则形状等。凸出部22沿第一方向F1凸出于底座部21,凸出部22由底座部21的表面沿第一方向F1向远离底座部21的方向延伸。凸出部22与底座部21的连接方式不限,
可以为一体式连接、焊接、螺纹连接等。
请参照图5,底座部21至少部分嵌于安装槽101中,即底座部21的至少一部分位于安装槽101的槽内空间,以使底座部21能够挂载于安装槽101内,从而实现挂载件20在挂载板10上的嵌入挂载式连接,通过安装槽101的槽壁与底座部21配合可以实现对挂载件20的限位固定。
其中,底座部21可以一部分嵌于安装槽101中,例如底座部21的另一部分可以通过开口102伸出安装槽101外,或安装槽101沿第二方向F2或第三方向F3的端部敞开使底座部21的另一部分能够沿第二方向F2或第三方向F3伸出安装槽101外,这里第一方向F1、第二方向F2和第三方向F3两两相交,例如图1所示第一方向F1为左右方向、第二方向F2为上下方向、第三方向F3为前后方向。
或者,底座部21可以完全位于安装槽101中,底座部21不外露使电池箱体100的外部整洁,不易出现外露部分被碰触、撞击影响挂载件20安装强度的问题,并且底座部21完全用于与安装槽101配合起到嵌入挂载功能,有利于提高挂载配合面积,挺高挂载安装可靠性。
请继续参照图5,凸出部22的至少部分沿第一方向F1经由开口102伸出安装槽101外,以使凸出部22的伸出部分能够用于与其他结构连接,实现电池箱体100在车体等安装位置的安装固定。例如,凸出部22的伸出部分可以与设于车底纵梁的锁合结构锁附,以实现包括电池箱体100的电池1000在车底纵梁的可拆卸安装。并且,凸出部22根据需要也可以与开口102的边沿配合起到支撑、挂载作用,以提高挂载的可靠性。
在本申请的实施例中,挂载件20与挂载板10通过嵌入挂载式结构连接,形成挂载件20与挂载板10之间的互锁连接,连接结构强度高,可靠性好。并且,嵌入挂载连接方式对挂载板10的厚度要求较低,无需增大挂载板10的厚度也能实现可靠的连接效果,因此有利于减小挂载板10的占用空间,进而在电池箱体100整体体积一定的情况下可以增大电池箱体100内部的空间,电池箱体100用于安装电池单体的空间更大,有利于提高空间利用率、能量密度和电池1000的续航能力。而在电池箱体100内部空间一定的情况下,有利于减小电池箱体100的整体占用空间,进而减小电池1000的整体占用空间,使电池1000能够满足较小空间的安装需求。例如在电池1000安装于车体下方的实施例中,有利于增大电池1000的离地高度,提高车辆行驶过程中的电池1000安全性,且有利于满足车体下方安装空间较小的车型安装需求。
根据本申请实施例的电池箱体100,通过挂载件20的底座部21至少部分嵌入挂载板10的安装槽101,使挂载件20与挂载板10实现嵌入挂载式安装,有利于提升结构可靠性和强度,并且有利于降低对空间的影响,提高电池箱体100内用于安装电池单体的
空间、提高能量密度和电池1000续航能力,有利于满足电池箱体100在较小安装空间的安装需求。
根据本申请的一些实施例,请参照图3-图5,挂载件20通过底座部21固定连接于挂载板10。即挂载件20相对于挂载板10不可移动,例如在第一方向F1、第二方向F2和第三方向F3上均不可移动,以使电池箱体100通过挂载件20安装于车体等安装位置时位置稳固,有利于提高电池1000的安全性,并且挂载件20与挂载板10的连接结构强度和可靠性得以大大提高。
这里,底座部21与挂载板10的固定连接方式包括、但不限于过盈连接、铆接等。例如通过安装槽101沿第一方向F1相对的两槽壁夹紧底座部21实现固定;再例如在图5所示的示例中,底座部21与挂载板10采用压力机进行锚点,实现连接,连接结构牢固,且连接过程无需焊接和螺栓安装。
在一些实施例中,请参照图2和图5,底座部21可以为厚度方向平行于第一方向F1的板体,结构更简单且占用空间更小,并且便于底座部21与挂载板10的连接操作,例如便于提高锚点连接的强度。
在本申请的一些实施例中,请参照图2和图5,开口102沿第二方向F2的最大尺寸小于底座部21沿第二方向F2的最大尺寸,第二方向F2与第一方向F1相交。
需要说明的是,开口102沿第二方向F2的尺寸可以处处相等,也可以不完全相等。例如图2所示开口102沿第三方向F3延伸呈长条形,且开口102第三方向F3上任意位置处沿第二方向F2的尺寸均为定值,以使开口102沿第二方向F2的尺寸处处相等。再例如在另一些实施例中,开口102在第三方向F3上不同位置处沿第二方向F2的尺寸可以不相等。同理,底座部21沿第二方向F2的尺寸可以处处相等,也可以不完全相等。
这里,开口102沿第二方向F2的最大尺寸,指开口102用于与底座部21配合的区域沿第二方向F2的最大尺寸,而开口102与底座部21错开的区域沿第二方向F2的最大尺寸可以小于、等于或者大于底座部21沿第二方向F2的最大尺寸。
第二方向F2与第一方向F1相交,是指第二方向F2与第一方向F1的夹角为锐角、直角或钝角的任意角度。例如图2所示第二方向F2与第一方向F1相互垂直。
通过开口102沿第二方向F2的最大尺寸小于底座部21沿第二方向F2的最大尺寸,使开口102边沿处安装槽101的槽壁能够在第一方向F1上对底座部21形成阻挡,以阻止底座部21沿第一方向F1由开口102脱出,提高了底座部21在安装槽101内安装的稳定性。
此外,由于安装槽101能够容纳底座部21,因此安装槽101沿第二方向F2的最大尺寸大于或等于底座部21沿第二方向F2的最大的尺寸,因此安装槽101沿第二方向
F2的最大尺寸大于开口102沿第二方向F2的最大尺寸,由此,在垂直于第一方向F1的截面上,安装槽101和开口102的可以大体形成为L型或T型结构,对应的挂载件20垂直于第一方向F1的截面大体为L型或T型,使挂载件20与挂载板10挂载连接稳固。
在一些实施例中,请继续参照图2和图5,开口102沿第二方向F2的最大尺寸大于或等于凸出部22沿第二方向F2的最大尺寸。其中,开口102沿第二方向F2的最大尺寸等于凸出部22沿第二方向F2的最大尺寸的实施例中,使开口102的边沿能够与凸出部22配合实现第二方向F2上对挂载件20的限位,提高挂载件20的稳定性。开口102沿第二方向F2的最大尺寸大于凸出部22沿第二方向F2的最大尺寸的实施例中,开口102可以为底座部21与挂载板10的连接提供足够的操作空间,例如可以便于压力机通过开口102伸入安装槽101内以对底座部21和安装槽101的槽壁进行锚点,使挂载件20安装操作更方便。
在本申请的一些实施例,请参照图2,安装槽101由挂载板10的至少部分折弯形成。折弯方式成型不仅使安装槽101加工容易,满足多样化形状、尺寸的加工需求,而且可以提高挂载板10的结构强度。
例如图2和图5所示,挂载板10先向下延伸,然后折弯向上、再折弯向下延伸之后折弯向上延伸,以形成安装槽101,然后再折弯向下延伸以形成安装槽101的开口102。需要说明的是,挂载板10的向下延伸的板体和向上延伸的板体,可以间隔开一定间隙,也可以彼此贴合。
在一些实施例中,请继续参照图2,挂载板10包括沿第一方向F1层叠设置的内层壁11和外层壁12,外层壁12折弯形成安装槽101。
这里,内层壁11和外层壁12的内外方向,是指内层壁11位于外层壁12的内侧,即位于外层壁12的靠近电池箱体100的内腔(用于安装电池单体的安装腔)的一侧。
内层壁11和外层壁12形成为双层结构,以提高挂载板10的整体结果强度,并且通过外层壁12折弯形成安装槽101,使挂载件20可以挂载于挂载板10的外侧,以便于与安装位点连接。外层壁12折弯过程中,可以占用内侧壁和外层壁12之间的空间,而不会因设置安装槽101导致挂载板10的整体沿第一方向F1的厚度增大,有利于降低对空间的影响。
例如图2和图5所示,外层壁12先向下延伸,然后向内且向上折弯,再向内且向下折弯,再向外且向上折弯,最后向外且向下折弯,以形成安装槽101和开口102,安装槽101位于外层壁12的外表面与内层壁11之间,以避免增大挂载板10的整体厚度。
需要说明的是,内层壁11和外层壁12可以为一体件,例如可以通过一块金属板通
过折弯得到相连的内层壁11和外层壁12,最后将金属板的起始边沿和末端边沿通过焊接等方式连接,以使内层壁11和外层壁12之间形成型腔,以提高挂载板10的结构强度。再例如,内层壁11和外层壁12可以通过不同金属板各自成型,最后将内层壁11的两侧边沿分别与外层壁12的两侧边沿通过焊接等方式连接,以使内层壁11和外层壁12之间形成型腔,以提高挂载板10的结构强度。
在一些实施例中,请参照图2和图6,图6为本申请一些实施例提供的电池箱体100的主视图。挂载板10沿第三方向F3的两端分别设有封堵件13,封堵件13连接内层壁11和外层壁12,第三方向F3、第二方向F2和第一方向F1两两相交。
通过封堵件13可以提高内层壁11和外层壁12的连接强度,进而提高挂载板10的整体结构强度。并且,封堵件13还可以封堵内层壁11和外层壁12之间型腔沿第三方向F3的端部敞口,防止外部灰尘等杂质进入型腔内。
本申请对封堵件13与内层壁11、外层壁12的连接方式不限,例如可以为焊接、粘接、过盈配合等。在一些实施例中,封堵件13可以为板体,板体垂直于第三方向F3的形状与型腔垂直于第三方向F3的形状相同,以提高封堵件13的封堵效果,且封堵件13可以不封堵安装槽101的端部敞口,以便于挂载件20损害时能够通过端部敞口对挂载件20进行拆装更换。
根据本申请的一些实施例,请参照图1和图6-图7,图6为本申请一些实施例提供的电池箱体100的主视图,图7为图6沿D-D线所示方向的剖视图。安装槽101沿第三方向F3延伸,挂载件20有多个,且多个挂载件20沿第三方向F3间隔嵌设于安装槽101中,第三方向F3与第一方向F1相交。由此,多个挂载件20可以从第三方向F3上多个位点对电池箱体100安装至安装位点,以提高电池箱体100安装的稳定性。
例如在电池1000安装于车底纵梁的一些实施例中,第三方向F3可以平行于车底纵梁的长度方向,多个挂载件20可以从车底纵梁长度方向上的多个位点实现电池1000与车底纵梁的连接,以提高电池1000受力的均匀性、提高安装的可靠性。
并且,多个挂载件20可以与同一个安装槽101相配合,以简化电池箱体100的结构,简化挂载件20在挂载板10上的装配难度。在一些具体实施例中,安装槽101沿第三方向F3的两端敞开,挂载件20的底座部21可以通过安装槽101沿第三方向F3的端部装入安装槽101内,移动至所需位置后再将底座部21与挂载板10进行固定,挂载件20装配便捷。并且对于不同挂载件20数量、挂载件20不同固定位置的电池箱体100,挂载板10的结构可以相同,以提高挂载板10的适配性。
根据本申请的一些实施例,请参照图1、图3-图4和图6-图7,挂载板10为两个且沿第一方向F1间隔开布置。例如,两个挂载板10上安装槽101的开口102相对敞开,
使两侧的挂载件20能够由所在开口102彼此相对伸出;或者,两个挂载板10上安装槽101的开口102相背敞开;再或者两个挂载板10上安装槽101的开口102同向敞开。
在电池箱体100安装于安装位点时,可以由安装位点在第一方向F1上的两处进行安装,例如可以由车底纵梁宽度方向的两侧与车底纵梁进行连接,一方面可以提高电池箱体100在车底纵梁上的安装稳定性,另一方面,电池箱体100的至少一部分可以位于车底纵梁宽度方向的两侧,以充分利用车底纵梁两侧的空间,提高所能安装电池1000的体积和续航能力。
根据本申请的一些实施例,请参照图1和图8,电池箱体100具有凹部301,凹部301具有两个凹部侧壁31和凹部底壁32,两个凹部侧壁31沿第一方向F1相对,凹部底壁32连接两个凹部侧壁31。
此外,至少一个凹部侧壁31包括挂载板10,换言之,挂载板10可以形成为凹部侧壁31的一部分并安装于凹部侧壁31的其他结构上,或者挂载板10形成为凹部侧壁31。
凹部侧壁31可以为一体式侧壁,也可以由多个侧壁拼接而成;凹部底壁32可以为一体式壁,也可以由多个壁拼接而成。
由此,凹部301可以用于容纳用于与电池箱体100连接的外部部件,例如容纳车底纵梁。并且挂载件20设于凹部侧壁31上,能够由外部部件的侧部与外部部件连接,使电池箱体100与外部部件的连接操作更便捷,提高连接的可靠性,并且凹部侧壁31可以对挂载件20的连接结构进行遮挡保护,防止连接结构被损坏或沾染泥污。
其中,两个凹部侧壁31均包括挂载板10的实施例中,两个凹部侧壁31上的安装槽101的开口102彼此相对敞开,且两个凹部侧壁31上的挂载件20穿过开口102后彼此相对延伸并伸入凹部301内。挂载件20可以从两侧与凹部301内的外部部件进行连接,连接操作方便且有利于提高连接的稳定性。并且,电池箱体100的至少部分可以位于外部部件沿第一方向F1的两侧,以充分利用外部部件的侧部空间,提高空间利用率和电池的续航能力。
根据本申请的一些实施例,请参照图8,电池箱体100具有两个第一侧壁33和两个第二侧壁34,两个第一侧壁33沿第一方向F1相背,两个第二侧壁34沿第三方向F3相背。相背,即两个侧壁上,安装槽101的开口102朝向相反,挂载件20穿出开口102后彼此远离延伸。
其中,在一些实施例中,至少一个第一侧壁33包括挂载板10;在另一些实施例中,至少一个第二侧壁34包括挂载板10;在又一些实施例中,至少一个第一侧壁33包括挂载板10,且至少一个第二侧壁34包括挂载板10。
这里,侧壁包括挂载板10是指,挂载板10可以形成为侧壁的一部分并安装于侧壁
的其他结构上,或者挂载板10形成为侧壁。第一侧壁33可以为一体式侧壁,也可以由多个侧壁拼接而成。第二侧壁34可以为一体式侧壁,也可以由多个侧壁拼接而成。
由此,挂载件20可以设于第一侧壁33和第二侧壁34的至少一处,以使电池箱体100可以由侧面与外部部件进行连接,提高连接的稳定性,且使连接操作更方便。并且,在两个第一侧壁33均包括挂载板10或者两个第二侧壁34均包括挂载板10的实施例中,可以由第一方向F1的两侧或者由第三方向F3的两侧对电池箱体100进行安装,可以提高电池箱体100受力的均匀性和安装稳定性。

在一些实施例中,电池1000还包括电池单体,电池单体安装于电池箱体100内,以通过电池箱体100对电池单体进行遮挡和保护。

挂载板10具有长度方向沿第三方向F3延伸、厚度方向沿第一方向F1延伸的型腔,以使挂载板10的结构强度满足电池1000的强度需求和安全需求。并且,挂载板10的外层壁12向内折弯以形成安装槽101,安装槽101位于型腔内,占用型腔内空间,因此不会使挂载板10的厚度以及电池1000的整体占用空间增大,对电池1000的能量密度不会产生不良影响。
挂载件20包括底座部21和凸出部22,底座部21为板体且与安装槽101的内槽壁和外槽壁夹紧配合,底座部21还与安装槽101的内槽壁和外槽壁中的至少一个通过压力机锚点连接。凸出部22为设于底座部21的柱体,柱体沿第一方向F1穿出安装槽101的开口102,以使柱体的伸出部分能够形成为锁销,以便于与车底纵梁侧面的锁附件可拆卸连接。
底座部21和凸出部22垂直于第三方向F3的截面构成T型,安装槽101垂直于第三方向F3的截面形成为T型,使底座部21嵌入安装槽101内且凸出部22由安装槽101的开口102伸出后,挂载件20与挂载部形成嵌入挂载式连接,形成互锁,以提升挂载件20与挂载板10之间连接结构的可靠性和强度,满足一些较高强度需求的使用。
需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互结合。
以上仅为本申请的优选实施例而已,并不用于限制本申请,对于本领域的技术人员来说,本申请可以有各种更改和变化。凡在本申请的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本申请的保护范围之内。
