Automobile controller lower bracket of automobile

Abstract

The invention discloses an automobile controller lower bracket of an automobile and a preparation method of the automobile controller lower bracket. The automobile controller lower bracket comprises atop plate, two side plates and two bottom plates. The bottom plates are arranged on the positions, below the top plate, of the left side and the right side. The automobile controller bracket is madeof cold-rolled low-carbon steel and has very good tenacity, the effect of a chemical siliconizing agent is promoted through surface lasers, thus the surface of the bracket is provided with a siliconized layer, and the surface hardness and corrosion resistance are greatly improved; and before the effect of the siliconizing agent, ELID grinding is further conducted, thus the surface of the bracket is provided with nanoscale protrusions, the superficial area of the bracket is increased, and when the siliconizing agent acts, the thickness of a corrosion-resistant layer is increased.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a lower bracket of a vehicle controller. Background technique [0002] Energy saving and emission reduction are the main purposes of current automobile research, and electric vehicles are the mainstream of new energy vehicle development in the future. Electric vehicle control technology is one of the key technologies for the development of electric vehicles. The vehicle controller is the core of the control system. The normal driving, safety, fault diagnosis and treatment of the car, and the monitoring of the vehicle status play a key role. The vehicle controller is the powertrain controller. As the core control component, it collects accelerator pedal signals, brake pedal signal signals and other component signals, and makes corresponding judgments to control the actions of the lower-level component controllers to drive the car to run normally. Vehicle driving adop...

AI Technical Summary

Problems solved by technology

[0003] In the process of driving, the vehicle usually passes through the uneven bottom surface, and the vibration of the vehicle body is severe. As the safety performance device of the vehicle, the vehicle controller has to be very sensitive. When it is constantly vibrating, it is easy to cause the control device failure

[0004] When most metals have good hardness, they can improve their wear resistance and corrosion resistance. Soft metals can be used in springs, reeds and other applications. Although they have certain toughness, they are not wear-resistant. A large amount of rust will appear in a humid environment

[0005] The present invention has the characteristics of the prior art and mainly solves the problem that the toughness of the existing controller bracket is high and the hardness does not meet the requirements, or the hardness is good but the flexibility is poor
