Abstract

The invention discloses an electric automobile battery pack mounting structure which comprises a pair of doorsill beams, a front baffle lower cross beam and a rear floor front cross beam. The front baffle lower cross beam is arranged at the front ends of the doorsill beams, and the rear floor front cross beam is arranged at the rear ends of the doorsill beams. The doorsill beams, the front baffle lower cross beam and the rear floor front cross beam are all of hollow aluminum profile structures and each internally provided with a nut plate mounting strip. A battery mounting nut plate is arranged on each nut plate mounting strip. Through holes corresponding to screw holes in the battery mounting nut plates are formed in bottom plates of the doorsill beams, a bottom plate of the front baffle lower cross beam and a bottom plate of the rear floor front cross beam correspondingly. Each nut plate mounting strip is of an aluminum batten structure, the weight is low, lightweight of an electric automobile is facilitated, and the driving mileage of the electric automobile can be effectively prolonged; and the overall stress is uniform, batteries are reliably fixed and conveniently mounted, and mounting structures are located inside the beams correspondingly, so that no external space is occupied.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle battery pack installation structure. Background technique [0002] As a new energy vehicle, electric vehicles have the advantages of energy saving and environmental protection. Electric vehicles are becoming more and more research hotspots in the automotive field. At present, the common problem in the field of electric vehicles is that the battery life of electric vehicles is limited, which limits the popularization and application of electric vehicles. [0003] Most of the power batteries on the existing car body are fixed on the underbody beam through steel brackets. The steel bracket is located at the lower part of the underbody beam and occupies the battery layout space. It is unfavorable to effectively extend the cruising range of electric vehicles. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the technical...
