Dashboard beam assembly for pure electric vehicles

Abstract

The invention belongs to the technical field of car manufacturing. A novel instrument board beam assembly of blade electric vehicles comprises a beam body, a left instrument board beam connecting plate, a right instrument board beam connecting plate and a longitudinal arm beam; the beam body comprises a left tube beam and a right tube beam which are fixed in a matched and sleeved manner, the left tube beam comprises an upper left tube beam and a lower left tube beam, the upper left tube beam and the lower left tube beam are in U-shaped groove shapes, and openings of the upper left tube beam and the lower left tube beam are opposite; the right tube beam comprises an upper right tube beam and a lower right tube beam, and the upper right tube beam and the lower right tube beam are provided with an upper steering wheel support and a lower steering wheel support; and the upper steering wheel support and the upper right tube beam are of an integrated molding structure, and the lower steering wheel support and the lower right tube beam are of an integrated molding structure. According to the novel instrument board beam assembly, the left tube beam and the right tube beam are welded together in a sleeved manner, by means of the structural design, the material using amount of parts is reasonably distributed, and material waste is avoided; and meanwhile, aluminum alloy die-cast formation is adopted in the tube beams, and the overall weight is reduced while the performance requirement is met.

Description

Technical field [0001] The invention belongs to the technical field of automobile manufacturing, and specifically relates to an instrument panel beam assembly of a pure electric automobile. Background technique [0002] In recent years, in response to national policies, the state and auto factories have vigorously developed pure electric vehicles. For electric vehicles, in order to increase the cruising range of electric vehicles based on the original power, one of the important solutions is the lightweight design of the vehicle body. The invention introduces a new type of aluminum alloy material automobile instrument panel beam assembly. Because the density of aluminum is one-third that of iron, the application of aluminum alloy materials can greatly reduce its quality. At the same time, customers' requirements for automobile performance are becoming more and more stringent. The instrument panel beam assembly is the support frame of the instrument panel system. The instrument ...

AI Technical Summary

Problems solved by technology

For ordinary cars, the crossbeam on the side of the steering wheel needs to be installed with heavy parts such as the steering wheel, so the diameter of the crossbeam needs to be designed to be large, so the diameter of the crossbeam is usually designed to be large. This design method is wasteful compared to the instrument panel crossbeam material

[0004] The steering wheel mounting bracket needs to be welded on the instrument panel beam. Welding the steering wheel mounting bracket on the instrument panel beam will have problems such as complex fixture design, low welding efficiency, poor welding quality, and high failure rate.
