Multiple connecting columns 2 are vertically oriented, each end of which is removably connected to two adjacent bracket modules 1 above and below. At least two diagonal bracing modules 5 are positioned on opposite sides of the multiple bracket modules 1 and are removably connected to the multiple bracket modules 1. At least two diagonal bracing modules 5 and the bottom bracket module 1 in the multiple bracket modules 1 are removably connected to a connecting beam 3, which is removably connected to the vehicle frame.

[0073] The present battery frame is modularly assembled using multiple bracket modules 1, multiple connecting columns 2, at least two diagonal bracing modules 5, and connecting beams 3, which can improve assembly efficiency. At the same time, each module is detachably connected to facilitate the loading and unloading of the entire battery frame, avoiding welding defects between modules that lead to overall scrapping, and timely replacement of damaged modules to extend the service life of the battery frame and reduce the cost of the battery frame. The connecting beams 3 in the battery frame can be detachably connected to the vehicle frame, which is also convenient for loading and unloading with the vehicle frame. Furthermore, the present battery frame uses multiple connecting columns 2 to detachably connect adjacent bracket modules 1 to form a multi-layer bracket structure for supporting batteries, so that the number of bracket module 1 layers can be flexibly adjusted according to the number of batteries to be installed.
