下面将结合附图对本申请的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
在本申请的描述中,需要说明的是,术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本申请和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本申请的限制。此外,术语“第一”、“第二”、“第三”仅用于描述目的,而不能理解为指示或暗示相对重要性。
在本申请的描述中,需要说明的是,除非另有明确的规定和限定,术语“安装”、“相连”、“连接”应做广义理解,例如,可以是固定连接,也可以是可拆卸连接,或一体地连接;可以是机械连接,也可以是电连接;可以是直接相连,也可以通过中间媒介间接相连,可以是两个元件内部的连通。对于本领域的普通技术人员而言,可以具体情况理解上述术语在本申请中的具体含义。
参见图1至图4所示,本申请提供的模组端板102被设置于电池包内的电池模组101的端部,电池模组101的两端均设置有模组端板102,以从两侧对电池模组101夹持固定。电池模组101从模组端板102处引出正极连接线和负极连接线,以连接输出极组件。
具体来说,模组端板102包括端板本体103,端板本体103的顶面开设有多个第一固定部104和多个第二固定部105,以分别固定正极输出极组件106和负极输出极组件107。对于不同串数的电池模组101来说,连接正极输出极组件106的正极连接线和连接负极输出极组件107负极连接线的引出位置存在差异。
参见图1和图4所示,正极连接线从端板本体103的右侧引出,端板本体103的右侧设置了两个间隔排布的第一固定部104,对于一些电池模组101的正极连接线的引出位置靠近右侧的第一固定部104的情况下,电池模组101的正极输出极组件106可安装于右侧的第一固定部104,以连接正极连接线;对于一些电池模组101的正极连接线的引出位置靠近左侧的第一固定部104的情况下,电池模组101的正极输出极组件106可安装于左侧的第一固定部104,以连接正极连接线。对于负极连接线来说,原理等同于正极连接线,在此不再赘述。
也就是说,本申请的模组端板102可适用于不同串数的电池模组101,以便于不同位置的正极连接线与正极输出极组件106的连接,以及不同位置的负极连接线与负极输出极组件107的连接,从而可增加模组端板102的通用性,便于批量制造。
该实施例可选的方案中,第一固定部104的轮廓与正极输出极组件106的安装部适配,以对正极输出极组件106的可靠固定。第二固定部105的轮廓与负极输出极组件107的安装部适配,以对负极输出极组件107的可靠固定。
进一步地,为了防止正、负极输出极组件错插,将第一固定部104与第二固定部105设置为防呆结构。例如,可选取安装部的形状、结构或尺寸不同的正、负极输出极组件,对应地,第一固定部104与第二固定部105的形状、结构或尺寸不同,很容易区分插接位置。
可选地,第一固定部104和第二固定部105均为孔结构或者槽结构,图1中示出的第一固定部104与第二固定部105均为菱形孔,但对应正、负极的菱形孔的角度不同,在保证正、负极输出极组件的引出侧都向外侧的前提下,正、负极输出极组件不会出现差错的情况。
该实施例可选的方案中,沿端板本体103的高度方向,端板本体103的外侧面形成有第一绑扎区域(图2中上部的点划线框出的区域)、及位于第一绑扎区域下方的第二绑扎区域(图2中下部的点划线框出的区域)。其中,第一绑扎区域形成有第一限位凹槽,第一限位凹槽内设置有第一绑扎件108,第一限位凹槽在第一绑扎件108的宽度方向上的两侧对其限位,以避免第一绑扎件108移动而绑扎失效,第一绑扎件108具体可为钢扎带。
同理地,第二绑扎区域形成有第二限位凹槽,第二限位凹槽内设置有第二绑扎件109,第二绑扎件109具体可为塑料扎带。第一绑扎件108和第二绑扎件109共同将端板本体103和电池模组101绑扎,以保证二者可靠固定。具体地,第一限位凹槽和第二限位凹槽的槽深在1.5mm-2.5mm之间,优选地,第一限位凹槽和第二限位凹槽的槽深为1.5mm。
由于钢扎带一般采用中间有搭接的结构形式,该实施例可选的方案中,第一绑扎区域的中部形成有凹陷部(图2中的虚线框出的区域,为了便于加工,凹陷部的底面一直向上延伸至端板本体103的顶面),凹陷部用于避让第一绑扎件108形成的搭接凸起110,以避免第一绑扎件108的搭接位置向外侧凸出,影响电池包整体结构。凹陷部相对于第一限位凹槽进一步下陷,具体地,凹陷部相对于端板本体103的外侧面的下陷深度为1.5mm-2.5mm。
如图2所示,端板本体103一体压铸成型,端板本体103的外侧面设置有横向和纵向分布的加强筋111,以提升端板本体103的强度。基于外侧面加强筋111的结构,槽壁不是连续的壁面,槽沿都是由间隔设置的竖向的加强筋111上的台阶结构组合形成的。在端板本体103的长度方向上的凹陷部的两侧,第一限位凹槽靠近端板本体103的顶面的槽沿包括多个间隔设置的限位凸起112。具体以图1中的凹陷部的左侧结构为例说明,第一限位凹槽靠近端板本体103的顶面的槽沿包括两个限位凸起112,两个限位凸起112形成的槽沿的结构即可对硬度较高的钢扎带固定,且能够精简该处的结构,便于制造。
该实施例可选的方案中,第一限位凹槽的槽底和槽壁的连接处圆弧过渡,第一限位凹槽的槽口边沿圆弧过渡;第二限位凹槽的槽底和槽壁的连接处圆弧过渡,第二限位凹槽的槽口边沿圆弧过渡。第一限位凹槽和第二限位凹槽没有尖角结构,避免尖角结构硌伤第一绑扎件108和第二绑扎件109。
该实施例可选的方案中,端板本体103开设有至少一个固定孔113,固定孔113贯穿端板本体103的顶面和底面,优选地,固定孔113为腰形孔,以满足电池模组101长度公差的装配要求。固定孔113处设置有连接件114,以将端板本体103与电池包的下壳体连接。如图4所示,端板本体103开设有四个固定孔113以保证端板本体103与下壳体连接可靠,在端板本体103的两端分别设置有一个固定孔113,在端板本体103的中部设置有两个固定孔113,连接件114具体可为螺栓。
参见图1和图4所示,螺栓的头部压接在端板本体103的顶面,由于延伸至端板本体103的顶面的凹陷部的存在,端板本体103对应凹陷部的位置厚度较薄、顶面的面积较小,螺栓安装面容易产生压溃现象。故在端板本体103的顶面设置有相对于凹陷部凸出的扩边沿115,扩边沿115用于承载连接件114的头部,从而增加此处的螺栓头部的压接面积。
该实施例二中的模组端板是在上述实施例基础上的改进,上述实施例中公开的技术内容不重复描述,上述实施例中公开的内容也属于该实施例二公开的内容。
参见图1所示,该实施例可选的方案中,端板本体103靠近电池模组101的一侧的角为倒角结构116,且倒角结构116的边缘与端板本体103之间圆弧过渡。也就是说,端板本体103靠近电池模组101的一侧没有尖角结构,在电池包进行机械测试时,避免端板本体103歪斜造成尖角部分挤压电池模组101,以致电池模组101的损坏的问题。
可选地,端板本体103的两侧部形成有加热膜限位槽117,对于侧面设置有加热膜的模组,热膜限位槽可对加热膜的出线的定位。
该实施例可选的方案中,端板本体103开设有两个间隔设置的吊装孔118;吊装孔118贯穿端板本体103的外侧面和内侧面,且两个吊装孔118在端板本体103的长度方向上对称设置,在吊装模组端板102时,可保证吊装受力平衡。
该实施例可选的方案中,端板本体103的底部设置有连接板119,连接板119的一侧板面与端板本体103的内侧面平齐,连接板119的另一侧板面与端板本体103的底面形成避让空间,在避让空间处可容纳电池包的下壳体设置的横梁。连接板119的具体厚度在1.5mm-2mm之间。优选地,连接板119的中部形成有避让口120,避免因连接板119的中部的变形使用长度超差。
本申请实施例三提供了一种电池包,包括上述任一实施例的模组端板,因而,具有上述任一实施例的模组端板的全部有益技术效果,在此,不再赘述。
最后应说明的是:以上各实施例仅用以说明本申请的技术方案,而非对其限制;尽管参照前述各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,或者对其中部分或者全部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范围。此外,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。
