Problems solved by technology

The installation positions of various components in the powertrain are scattered, resulting in a waste of space in the cabin
However, in the existing electric vehicles, the same device cannot be used to centrally fix and concentrate the bearing force, resulting in uneven distribution of force on the longitudinal beam of the vehicle, which is prone to large vibrations

Abstract

The invention relates to an internal component for a vehicle and in particular relates to a power assembly bracket device for a pure electric vehicle. The power assembly bracket device for the pure electric vehicle comprises a girder, wherein the girder is of a rectangular frame-shaped structure; a charger bracket is arranged on the upper surface of one end in the width direction of the girder, and a battery mounting plate is arranged on the upper surface of the other end in the width direction of the girder; a motor controller mounting plate is erected on the upper surface of the girder; a motor controller mounting bracket is arranged on the girder; an air conditioner compressor mounting frame is arranged below the girder; a speed reducer mounting bracket is fixedly arranged at the lower end of the girder; a vacuum booster pump mounting bracket and a vacuum liquid tank mounting bracket are arranged at one side opposite to the speed reducer mounting bracket; and a driving motor mounting plate is arranged below the battery mounting plate. The power assembly bracket device provided by the invention has the beneficial effects of intensively arranging parts in the power assembly, realizing unified bearing stress and ensuring that stress points of a longitudinal beam of the vehicle are fixed and have uniform stress.

Description

technical field [0001] The invention relates to an automobile internal component, in particular to a power assembly bracket device of a pure electric automobile. Background technique [0002] The powertrain of electric vehicles mainly includes electric motors, reducers, air-conditioning compressors and other equipment. The electric motors, reducers, battery packs, air-conditioning compressors and other equipment in existing electric vehicles are all welded and fixed on the front cabin beam. The cabin beam serves as the main support device. The vacuum booster pump, charger and other equipment are far away from the front cabin beam. As a result, the installation positions of various components in the powertrain are scattered, resulting in a waste of space in the engine room. However, in the existing electric vehicles, the same device cannot be used to centrally fix and centrally carry the force, resulting in uneven distribution of force on the longitudinal beam of the vehicl...
