Battery mounting bracket assembly of pure electric vehicle

Abstract

A battery mounting bracket assembly of a pure electric vehicle comprises left and right battery mounting brackets 1, a battery mounting cross beam 2, a rear floor 3 and left and right rear longitudinal beams 4. The battery mounting cross beam is welded with the left and right rear longitudinal beams and the rear floor, and the left and right battery mounting brackets are welded with the battery mounting cross beam and the rear floor to form a U-shaped structure. The battery mounting bracket assembly is characterized in that the battery mounting bracket comprises a first horizontal plate part 11, a first vertical plate part 12, a second horizontal plate part 13 and one or more reinforcing plate assemblies 14, the first horizontal plate part, the first vertical plate part and the second horizontal plate part are sequentially connected to form a structure substantially shaped like a Chinese character 'ji', the first vertical plate part is provided with a plurality of recesses 121, and thesecond horizontal plate part is connected with the reinforcing plate assemblies. According to the battery mounting bracket assembly of the pure electric vehicle, the rear floor and the rear longitudinal beams of an original vehicle are not changed, the battery mounting space is maximized, the bearing capacity of the rear floor is enhanced, and the strength of a battery mounting point is guaranteed.

Description

technical field [0001] The invention belongs to the field of pure electric vehicle body parts structure, and is used for the installation of power batteries (batteries), in particular to a pure electric vehicle battery installation bracket assembly. Background technique [0002] Electric vehicles developed on the basis of gasoline models need to add battery mounting brackets. It is necessary to minimize the amount of changes to the prototype vehicle, but also be limited to the space layout of auto parts, and at the same time meet the strength requirements of the battery installation point, which is convenient for popularization and production. Design is more difficult. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a battery mounting bracket assembly for pure electric vehicles, which does not change the rear floor and rear longitudinal beams of the prototype vehicle, maximizes the battery...
