具体实施方式
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。
图1为本申请第一个实施例所提供的电池模组的结构示意图，参照图1所示，本申请实施例提供了一种电池模组，包括侧板200和电池模组端板100，该电池模组端板100可以与侧板200固定连接，图2为本申请第一个实施例 所提供的电池模组端板的结构示意图，如图2所示，电池模组端板100可以包括本体10和连接于本体10的连接件20。对于单个电池模组端板100而言，电池模组端板100需要与相对设置的两个侧板200相连，因此可以将连接件20设置为两个，两个连接件20分别连接于本体10靠近侧板200的位置。图2中，仅以一个连接件20为例进行说明。
本体10主要用于承受电池膨胀力、设置安装孔等，因此可以设置本体10的材质为压铸铝，侧板200可以采用挤压铝，为了保证电池模组端板100的本体10与侧板200能够具有较好的可焊接性，本申请实施例设置连接件20，连接件20可以采用钣金铝。
在连接件20与侧板200激光焊接时，会有激光从二者连接的间隙射到电池模组端板100的内部，电池模组内的电池受到激光照射后容易引起高温爆炸，因此，上述连接件20设置有遮光部23，图3为本申请第一个实施例所提供的电池模组端板的俯视图，如图3所示，该遮光部23位于连接件20朝向侧板200的一侧，且位于连接件20与侧板200之间。通过设置遮光部23，避免了电池受到激光照射后引起的电池安全问题。
图4为本申请第一个实施例所提供的电池模组端板中本体的俯视图，参照图2至图4，本体10上可以设置有安装槽12，安装槽12沿着电池模组的高度方向(图1和图2中的Z向)贯通。连接件20插接于该安装槽12中。这样，本体10和连接件20分体设置，两者可以单独加工完毕以后再组装到一起，此种结构可以使得两者的加工更加灵活，并且可以更有效地提升两者之间的连接强度。
图5为本申请第一个实施例所提供的电池模组端板中连接件的俯视图，优选地，连接件20包括插接部21和连接部22，插接部21沿着电池模组的高度方向(图1和图2中的Z向)延伸，且与安装槽12插接配合，连接部22与电池模组的侧板200固定连接。上述的遮光部23则设置在连接部22与侧板200之间。
可以在本体10上仅设置一个安装槽12，连接件20具有插接部21，插接部21与安装槽12的插接配合具有足够的强度。上述插接部优选地设置为条形块状。如果设置片状或者板状结构与安装槽12配合，其插接强度不够，通常需要设置两个或两个以上的安装槽12才能保证连接的可靠性。因此，本申 请实施例提供的电池模组端板100通过设置连接件20具有条形块状的插接部21保证了本体10与连接件20的连接可靠性。连接件20还包括连接部22，通过该连接部22实现本体10与侧板200的固定连接。
如图2至图5所示，作为一种优选的实现方式，安装槽12和插接部21在电池模组的高度方向上的投影均为梯形。上述结构适用于安装槽12不便于开设在本体10的边缘位置，可以将安装槽12开设在本体10的第一侧面11上，安装槽12在第一侧面11上的位置不作具体限定，其可以位于第一侧面11的中间位置，也可以靠近第一侧面11的边缘，可以根据侧板200的尺寸进行适当的调整。
优选地，安装槽12靠近侧板200的一端开口尺寸小于远离侧板200的一端宽度尺寸，插接部21的外轮廓与安装槽12的内轮廓相匹配。这种开口窄内腔宽的结构，能够避免插接部21从安装槽12中脱出，提高了连接件20与本体10的连接可靠性。
图6为本申请第二个实施例所提供的电池模组端板的俯视图，图7为本申请第二个实施例所提供的电池模组端板中本体的俯视图，图8为本申请第二个实施例所提供的电池模组端板中连接件的俯视图。如图6至图8所示，在一种实施例中，安装槽12和插接部21在电池模组的高度方向上的投影还可以均是圆弧形。
优选地，安装槽12的圆心角大于180度，插接部21的外轮廓与安装槽12的内轮廓相匹配。这种开口窄内腔宽的结构，能够避免插接部21从安装槽12中脱出，提高了连接件20与本体10的连接可靠性。
当安装槽12开设在本体10的第一侧面11时，可以设置连接部22为板状结构，该板状结构的连接部22与侧板200贴合并焊接固定。由于板状结构的连接部22，且平面度精度不容易保证，在连接部22与侧板200焊接后，会有激光从二者连接的部位射到电池模组端板100的内部，电池模组内的电池受到激光照射后容易引起高温爆炸，因此设置连接部22包括第一板221和第二板222，第一板221和第二板222之间具有阶梯部231，上述遮光部23包括该阶梯部231，在连接部22与侧板200贴合并焊接后，该阶梯部231能够起到挡光的作用，因此避免了电池受到激光照射后引起的电池安全问题。
可以通过设置第一板221和第二板222的厚度不同实现上述阶梯部231， 也可以通过将相同厚度的第一板221和第二板222错开布置来实现上述阶梯部231。
图9为本申请第三个实施例所提供的电池模组端板的俯视图，图10为本申请第三个实施例所提供的电池模组端板中连接件的俯视图，图11为本申请第三个实施例所提供的电池模组端板与侧板连接的示意图。在上述实施例的基础上，遮光部23还优选地包括弹性件232，参照图9至图11，该弹性件232支撑在连接部22和侧板200之间，其可以与连接部22一体成型，在侧板200与连接件20焊接固定后，在焊点A的位置如果有激光透过，会被弹性件232遮挡，从而避免了激光对电池照射引发的电池安全问题。
基于上述结构，本申请实施例还提供一种电池模组，该电池模组包括侧板200和电池模组端板100，两者固定连接，且此电池模组端板100为上述任一实施例所述的电池模组端板100。
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。
