Battery pack mounting structure and vehicle

The utility model provides a battery pack mounting structure and a vehicle. The battery pack mounting structure comprises a threshold beam inner plate, a connecting assembly and a fastener, wherein abending cavity is formed in the threshold beam inner plate, the connecting assembly comprises a reinforcing plate and a plurality of threaded pipes arranged on the reinforcing plate, and the reinforcing plate is arranged in the bending cavity and connected with the side wall of the bending cavity; the fastener sequentially penetrates through the first through hole in the battery pack, the second through hole in the bending cavity and the threaded pipes so that the battery pack can be installed on the threshold beam inner plate. According to the battery pack mounting structure disclosed by theutility model, the reinforcing plate is arranged in the bending cavity of the threshold beam inner plate, so that the stress of a battery pack mounting point is locally expanded to a cavity body of the whole threshold beam inn
