Electric vehicle CPU control box

Abstract

The invention provides an electric vehicle CPU control box. The electric vehicle CPU control box comprises a box body and a cover board connected with the box body, wherein the left edge and the right edge of the cover board are respectively provided with four first installation holes, each first installation hole is provided with a cross sunk screw, the back surface of each first installation hole is provided with a pressing rivet nut, the right portion of the cover board is provided with a first through hole, the top, the left edge and the right edge of the cover board are respectively provided with a second through hole, a U-shaped protecting sleeve and a round pipe protecting sleeve are arranged inside the CPU control box, the center of the arc of the U-shaped protecting sleeve and the center of each second through hole are located on the same straight line, and the center of the round pipe protecting sleeve and the center of the first through hole are located on the same straight line. The electric vehicle CPU control box is made of aluminium, safety of the electric vehicle CPU control box is enhanced in an application process, strength and high-temperature resistance of the electric vehicle CPU control box are enhanced, faults of a CPU controller caused by deformation of the electric vehicle CPU control box are avoided, and the vehicle fault rate of a vehicle caused by deformation of the electric vehicle CPU control box is reduced.

Description

Technical field [0001] The invention belongs to the field of control equipment for new energy vehicles, and particularly relates to an electric vehicle CPU control box. Background technique [0002] A variety of electrical components such as high beam, low beam, fog lamp, starter, protection and other electrical components are installed in the control box of automobile electrical appliances. This has a good effect on improving the working conditions of electrical appliances. However, most control The box is a PP injection molded product, and the box may crack during use. The CPU generates high heat during the control process in a high-temperature environment, which causes the control box to deform or even burn, causing the tragedy of car crashes. The existing CPU control box also has the following shortcomings: 1. The material cost is relatively high; 2. It is difficult to guarantee the dimensional accuracy of the machining process. Summary of the invention [0003] The problem t...
