The invention relates to the field of battery packs, in particular to a frame assembly for a power battery, a power battery pack with the frame assembly and a vehicle body assembly, and the frame assembly comprises an inner frame and an outer frame; the outer frame is arranged on the periphery of the inner frame; the inner frame is connected with the outer frame through a flexible connecting mechanism; the flexible connecting mechanism comprises a connecting part; the connecting part comprises an elastic pin arranged on the inner frame; the elastic pins are connected to the outer frame through fasteners. The strength of the elastic pins is lower than that of the outer frame and the inner frame; the frame assembly disclosed by the invention adopts a double-frame structure; not only is the installation of the battery pack facilitated, but also the installation and fixation of the frame assembly on the vehicle body are facilitated; moreover, through the arrangement of the flexible connecting mechanism, when the vehicle body structure is greatly deformed in an accident, the deformation force cannot directly act on the power battery module on the inner frame.

    本发明涉及电池包领域,具体来说是一种动力电池用框架总成及具有该框架总成的动力电池包、车身总成,包括内框架以及外框架;所述外框架布置在内框架外围;所述内框架与外框架通过柔性连接机构相连接;所述柔性连接机构包括连接部;所述连接部包括设置在内框架上的弹性销;所述弹性销通过紧固件连接在外框架上;所述弹性销强度低于外框架以及内框架强度;本发明公开的框架总成采用双框架结构;不仅方便了电池包的安装,同时还方便了框架总成在车身上的安装固定;并且,在本发明中通过柔性连接机构的设置,车身结构在事故当中发生较大变形时,变形力不会直接作用于内框架上的动力电池模组。
