Abstract

The invention relates to a connecting structure of a power battery pack frame and a vehicle body mounting beam of a new energy vehicle and belongs to the technical field of automobile design and manufacturing. The connecting structure of the power battery pack frame and the vehicle body mounting beam of the new energy vehicle comprises the power battery pack frame, the vehicle body mounting beam,a mounting reinforcing plate, a nut box, a nut plate and a bolt, wherein the bolt sequentially penetrates through the through hole of the power battery pack frame, the through hole of the vehicle bodymounting beam, the through hole of the nut box, and the threaded hole of the nut plate; the nut plate is arranged inside the nut box, and the nut box forces the nut plate to move horizontally. The connecting structure of the power battery pack frame and the vehicle body mounting beam of the new energy vehicle optimizes the structural form of nuts and bolts in respect of tolerance matching, thereby effectively preventing the risk of pulling-out of standard components.
