附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。
图1是本发明实施例提供的电池包的结构示意图。
图2是图1中的电池包的分解结构示意图。
图3是图1中的电池包的仰视结构示意图。
图4是图1中的托盘的结构示意图。
图5是图4所示的托盘的分解结构示意图。
具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明提供一种车辆,包括车身以及电池包,车身的外表面设有安装位,电池包固定在安装位内。可以理解的是,安装位可以为凹槽,电池包安装在凹槽内。
请参阅图1-图3,电池包包括托盘10、多个电池20、配电箱30以及密封板40,托盘10内形成有容纳空间50,多个电池20与配电箱30均收容在容纳空间50内,且多个电池20与均配电箱30电连接,托盘10包括底板101,底板101上设有与容纳空间50连通的检修口101a,检修口101a与配电箱30相对设置,密封板40密封检修口101a,且密封板40与底板101可拆卸连接。可以理解的是,配电箱30内含有维修开关、保险等电路保护部件,售后对电池包的检修需要通过操作配电箱30进行,电池包检修口101a即用于满足售后对配电箱30的操作。密封板40与底板101通过螺栓可拆卸连接。电池包还包括护板150,护板150与底板101层叠,且护板150设于底板101的背向容纳空间50的一侧,护板150使得检修口101a露出。
电池包的底板101为自由板。即电池包的底板101不与车身连接,电池包的底板101朝向外界,检修口101a朝向外界。
从而,当电池包的配电箱30出现故障时,只需将密封板40拆卸,通过底板101朝向外界的检修口101a对配电箱30进行检修,无需拆卸电池包,检修效率高,解决了电池包检修口101a位于顶部上,需要将整个电池包从车身上拆下后通过顶部检修口101a对配电箱30进行维修,维修效率低,维修成本高的技术问题。
可选地,车身的底部的外表面设有安装位,电池包固定在底部的安装位内。当电池包安装在车辆底部的安装位内时,电池包的底板101朝下。即车辆处于正常的运行状态与停止状态时,电池包的底板101朝向地面。
从而,当电池包的配电箱30出现故障时,只需将车辆升起,检修人员在车底即可实现对配电箱30的检修,免去电池包拆卸工序。
请一并参阅图4-图5,托盘10还包括边梁60,边梁60与底板101连接形成容纳空间50,边梁60的高度大于等于电池20的高度。从而,通过边梁60的设置可以对容纳空间50内的电池20形成保护,避免了在行车过程中电池包受到侧向碰撞时,电池20容易受到挤压发生短路的技术问题,而且边梁60的设置也增强了托盘10的抗挤压强度。同时,由于边梁60的高度大于等于电池20的高度,边梁60可以将电池20完全包覆,外界的碰撞完全不会影响到电池20。可以理解的是,边梁60可以设于底板101的边缘,以使得容纳空间50的体积较大,进而较大的容纳空间50可以放置较多的电池20。
边梁60包括主边梁601与副边梁602,主边梁601上设有开口70,开口70与容纳空间50连通,副边梁602盖合开口70,且副边梁602与主边梁601可拆卸连接。具体的,副边梁602与主边梁601为可拆卸连接,主边梁601与副边梁602可以较容易连接,也较容易拆卸。边梁60为分体式结构。主边梁601与副边梁602连接的表面上设有溢胶槽,溢胶槽内设有密封胶,主边梁601与副边梁602通过密封胶粘接,且在主边梁601与副边梁602粘接固定后,还可以通过螺栓将主边梁601与副边梁602进一步紧固。
电池包还包括多个连接片80,每个电池包括顶面201,顶面201朝向开口70,每个电池20的顶面201上设有间隔设置的正极柱202与负极柱203,每个连接片80连接相邻两个电池20的正极柱202和负极柱203。具体的,多个电池20在容纳空间50内阵列排布,电池20的顶面201朝向开口70,正极柱202和负极柱203均朝向开口70,开口70的设置方便于连接片80与极柱(正极柱202与负极柱203)的连接。本申请中,连接片80连接相邻两个电池20的正极柱202和负极柱203的连接方式为焊接,当然也可以为其他的连接方式。通过多个连接片80连接相邻两个电池20的正极柱202和负极柱203,多个电池20串联连接。
从而,本申请通过副边梁602与主边梁601的可拆卸连接,当副边梁602从主边梁601上拆卸时,或者副边梁602未安装在主边梁601上时,可以使得主边梁601的开口70露出,在多个电池20装入容纳空间50后,通过主边梁601的开口70可以将连接片80安装固定在相邻两个电池20的正极柱202和负极柱203上,且当所有的连接片80均完成安装后,再将副边梁602安装连接在主边梁601上,这使得连接片80连接电池20的正极柱202和负极柱203的过程在托盘10内完成,工序简单,组装简单。这解决了将所有电池20通过连接片80焊接为一个整体后,通过工装束缚吊装或倒扣入托盘10内,工序繁琐复杂,组装难度高,且在工装束缚过程中使连接片80与极柱(正极柱202与负极柱203)之间的焊缝受力,焊缝受力不利于品质管控的技术问题。
可以理解的是,若连接片80连接相邻两个电池20的正极柱202和负极柱203的连接方式为焊接时,此处焊接一般通过激光焊接完成,由于激光焊接工艺所限,激光头到被焊接区域之间不可有阻挡物,而边梁60会阻碍激光焊接,所以边梁60需设置为分体式结构,需把前端的副边梁602设计成与主边梁601可拆卸连接,先把电池20装到托盘10内,再焊接连接片80,否则就需要先在托盘10以外完成极柱(正极柱202与负极柱203)和连接片80的焊接,再将电池20和连接片80整体装入托盘10内,但这会导致装配困难,且在电池20和连接片80整体装入托盘10的过程中会使连接片80焊缝受力。
此外,前侧检修口101a的设置,除了用于配电箱30检修,其目的还包含电池20的极柱(正极柱202与负极柱203)与连接片80之间的连接,如焊接。从而,本申请的检修口101a以及副边梁602与主边梁601的可拆卸连接可以使得电池20的极柱(正极柱202与负极柱203)与连接片80之间的连接更加容易,更加方便。
本申请通过边梁60的设置,可以实现边梁60对电池20的保护作用,强化托盘10的抗挤压强度;通过副边梁602与主边梁601的可拆卸连接,可实现正极柱202与连接片80的连接以及负极柱203与连接片80的连接均在托盘10内完成,提升电池包的工装质量,避免边梁60对连接片80连接极柱(正极柱202和负极柱203)的工序产生影响。可以理解的是,若连接片80连接相邻两个电池20的正极柱202和负极柱203的连接方式为焊接时,副边梁602与主边梁601的可拆卸连接,避免了副边梁602对极柱(正极柱202和负极柱203)焊接工序的影响。
在一个具体的实施例中,主边梁601的端部与底板101的端部共同形成开口70,副边梁602还与底板101可拆卸连接。可以理解的是,开口70延伸到了底板101,这增大了开口70的面积,通过开口70使得连接片80连接电池20的正极柱202和负极柱203的过程更加方便。
具体的,主边梁601包括第一边梁603、第二边梁604以及第三边梁605,第一边梁603与第二边梁604相对设置,第三边梁605与副边梁602相对设置,第一边梁603包括第一端603a以及与第一端603a相对设置的第二端603b,第二边梁604包括第三端604a以及与第三端604a相对设置的第四端604b,底板101包括连接端101b以及与连接端101b相对设置的固定端101c,第一端603a、第三端604a以及连接端101b位于同一侧,且第一端603a、第三端604a以及连接端101b形成开口70,副边梁602与第一端603a、第三端604a以及连接端101b均可拆卸连接,第二端603b、第四端604b以及固定端101c位于同一侧,第三边梁605固定连接第二端603b、第四端604b以及固定端101c。可以理解的是,第一边梁603、第三边梁605、第二边梁604以及副边梁602依次首尾相接形成边梁60。第一边梁603、第二边梁604、第三边梁605以及底板101一起成型。当电池包为一个完整的结构时,第一边梁603可以为右侧长边梁60,第二边梁604可以为左侧长边梁60,第三边梁605可以为后边梁60,副边梁602可以为前边梁60,开口70位于托盘10的前端。
从而,本申请通过第一边梁603、第三边梁605、第二边梁604以及副边梁602的设置,不仅可以对正极柱202和负极柱203进行保护,还可以对电池20的其他部位进行保护,实现对电池20的全方位保护。
托盘10还包括多个间隔边梁90,多个间隔边梁90间隔设于容纳空间50内,以将容纳空间50分割为多个子空间,一个子空间内设有部分电池20。间隔边梁90的设置可以增强托盘10的抗挤压强度,提高电池包的结构稳定性。可以理解的是,第一边梁603、第二边梁604、第三边梁605、底板101以及多个间隔边梁90一起成型。
在一个具体的实施例中,配电箱30设于电池20与副边梁602之间。具体的,配电箱30与电池20之间通过连接线连接,配电箱30设于电池20与副边梁602之间可以使得连接线的长度较短,节约成本,且线路简单,发生故障的概率低。可以理解的是,配电箱30位于电池包的前端。
电池包还包括结构胶110,结构胶110设于底板101与多个电池20之间,以将多个电池20固定粘接在底板101上。结构胶110用于将电池20固定在底板101上,避免电池20在电池包内的晃动。
电池包还包括直冷板120,直冷板120设于边梁60上,以盖合容纳空间50。直冷板120用于密封托盘10,且用于导出电池20上产生的热量。直冷板120与边梁60压合的区域使用密封泡棉或密封胶进行密封。直冷板120上设有多个弯曲的冷流道140,冷流道140用于冷媒的流动,以将电池20上产生的热量带走,直冷板120前端接口与冷媒进出口通过螺栓锁附。
电池包还包括导热结构胶130,导热结构胶130设于多个电池20与直冷板120之间。导热结构胶130不仅用于粘合固定电池20与直冷板120,还用于将电池20上产生的能量传递给直冷板120,通过直冷板120进行散热。
在电池包安装时,首先将多个电池20装入托盘10的容纳空间50内,多个电池20阵列排布,每个电池20的正极柱202和负极柱203朝向开口70,多个电池20与托盘10底板101之间使用结构胶110粘接固定;然后将连接片80安装于正极柱202和负极柱203上,激光焊接头通过托盘10开口70将连接片80焊接于正极柱202和负极柱203上;将配电箱30通过检修口101a装入托盘10,再安装检修口101a的密封板40;副边梁602安装至托盘10的开口70,主边梁601与副边梁602的接触面使用密封胶填充,二者通过螺栓紧固;在电池20顶部涂导热结构胶130,直冷板120安装至托盘10顶部,通过直冷板120实现容纳空间50密封,直冷板120与托盘10的边梁60之间压合区域使用密封泡棉(或密封胶)密封;直冷板120前端接口与冷媒进出口通过螺栓锁附,即完成电池包组装。
以上所揭露的仅为本发明较佳实施例而已,当然不能以此来限定本发明之权利范围,本领域普通技术人员可以理解实现上述实施例的全部或部分流程,并依本发明权利要求所作的等同变化,仍属于发明所涵盖的范围。
