在本实施例中，电芯24的外部由保护膜套23包覆，保护膜套23的上端开口使电芯24的电极露出，其中保护膜套23起绝缘作用，防止异物进入电芯之间影响电芯24供电。框边包括长边11b和短边11c，其中长边11b位于侧框11的上下两端，短边11c位于侧框11的左右两端，上护套25、电芯24以及下护 套22组成的电芯组件卡设在上下两长边11b之间以限制其在Z轴方向的位移电芯组件卡设在左右两端的短边11c之间以限制其在Y轴方向的位移，电芯组件卡设在两相对的框板11a之间以限制其在X轴方向的位移。短边11c上还设置有安装孔11d，压铆螺柱13则设置在安装孔11d中，其中螺柱朝外设置，压铆螺柱13穿过第一通孔12d并通过螺母将连接板12固定在两侧框11上，实现对侧框11的固定连接。
参照图4，下护套22排列设置在框架10底部并由框架10完全约束，盒体22a与盒体22a之间通过第一凹槽22c和第一凸起22b连接在一起。上护套25设置在下护套22的上方，其中盖体25a与其下方的盒体22a一一对应，盖体25a的内部的长宽尺寸与电芯24顶部的外围的长宽尺寸适配，盖体25a与盖体25a之间通过第二凹槽25b和第二凸起25e连接在一起，电极通孔25c位于盖体25a顶部靠近两端边缘处。本结构利用上、下护套22的壁厚控制电芯24间的距离，即预留电芯24充电时膨胀空间，有利于通风散热。
本发明设置了包括框架10、下护套22和上护套25的电池模组框架结构，其中框架10包括两相对设置的侧框11以及分别设置在所述侧框11的两端并用于连接两侧框11的连接板12；上护套25和下护套22各自排列设置在框架10中，电芯24则的上下两端分别由上、下护套22包裹固定，上护套25由侧框11的下部框边承接，上护套25的侧边由框架10的两侧板以及两端的框边包覆固定，同样上护套25的侧边由框架10的两侧板以及两端的框边包覆固定，上护套25的顶端与侧框11的上部框边抵接，由此实现了对电芯24的全方位的固定，同时通过在侧框11两端的框边上设置压铆螺柱13也方便侧框11与连接板12连接。此种固定方式主要通过侧边的尺寸来固定电芯24，减少了螺钉的应用，使电池模组框架结构的连接结构更加稳定。
优选地，所述第一凹槽22c和第二凹槽25b为燕尾槽。在本实施中第一凹槽22c和第二凹槽25b优选燕尾槽，第一凸起22b和第二凸起25e为燕尾形凸起。第一凸起22b的数量为两个并设置在盒体22a较长的一侧板上，第一凹槽22c则设置在另一较长侧板上，第一凸起22b与第一凹槽22c的位置相互对应。第二凸起25e的数量为两个并设置在盖体25a较长的一侧板上，第二凹槽25b则设 置在另一较长侧板上，第二凸起25e与第二凹槽25b的位置相互对应。通过设置燕尾形的连接结构，进一步提高盒体22a之间的连接强度，以及盖体25a之间的连接强度。
优选地，所述侧框11还包括自所述板体12a与所述板边12b相邻侧边向外延伸的固定边12c以及设置在所述固定边12c上的第二通孔，所述固定边12c的延伸方向与所述板边12b的延伸方向相反。在本实施例中通过设置固定边12c及第二通孔，可通过螺钉连接的方式或者销轴定位的方式将电池模组框架结构安装在电池仓中，或者也可设置安装板并在其上设置与第二通孔对应的螺孔，实现对多个电池模块的安装固定。
进一步的，所述框板11a上还设置有散热孔。其中散热孔为设在框板11a上两个并排设置的较大的方形孔，尽可能扩大方形孔的面积可加快热空气在电芯24之间的流通以加快散热。
在本实施例中，所述电池模组框架结构还包括设置在所述侧框11背对所述电芯24的一侧上的涡流风扇(图中未示出)，所述涡流风扇的进气侧孔与所述散热孔对应。涡流风扇的出气口则朝上设置，使热空气上升，以便外部环境中的冷空气从低处进入以加快散热。
本发明还提出一种电池模组，包括权上述的电池模组框架结构以及设置在所述电池模组框架结构中的电芯24。
进一步的，所述电池模组还包括金属板条21以及固定所述金属板条21的螺钉，所述金属板条21上设置有与所述电芯24的同性电极对应的连接孔，所述螺钉穿过所述连接孔与所述同性电极上的螺孔适配。
本发明通过设置安装电芯24的电池模组安装结构可用于组装并固定多个电芯24并形成电池模组，应对不同尺寸的电池容纳腔，可将多个电池模组组装在一起，通过将电芯24先并后串组成的特定规格型号的电池包，以便后续的维修、互换电池模组及电池的梯次利用。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。以上实施例仅表达 了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
