Battery pack bottom plate, battery pack frame and battery pack

The invention relates to the technical field of battery packs, and provides a battery pack bottom plate, a battery pack frame and a battery pack, the battery pack bottom plate mainly comprises a bottom plate body and a honeycomb plate, and the honeycomb plate and the bottom plate body are of an integrated structure. According to the scheme, the honeycomb plate and the bottom plate body are arranged to be of the integrated structure, so that the honeycomb plate can serve as a part of the integrated structure to jointly form the battery pack bottom plate, and the problem that in the prior art, the honeycomb plate needs to be installed on the battery pack bottom plate through bolts, and consequently the occupied space in the Z direction is large can be solved; according to the scheme, bolts do not need to be arranged between the honeycomb plate and the bottom plate body for installation and connection, the occupied space needed by the interior and the exterior of the battery pack due to the arrangement of the bo
