Problems solved by technology

[0004] During the use of the high-voltage power distribution cabinet of new energy vehicles, due to the high-speed operation of the car, the heat inside the power distribution cabinet will also rise, so heat dissipation is required. The air inlet direction of the fan heating device of the existing power distribution cabinet They are all fixed, and the wind always enters from one side and exits from the other. If this goes on for a long time, the mesh of the dust-proof net will be easily blocked, resulting in poor cooling effect

Abstract

The invention discloses a dustproof heat dissipation mechanism. The mechanism comprises an n-shaped frame, mounting cylinders and fan blades; the mounting cylinders are mounted on the two sides of thebottom of the n-shaped frame correspondingly; a motor is mounted in the middle of the top of the n-shaped frame; a semi-conical gear is mounted on the output shaft of the motor; a rotating shaft below the semi-conical gear is arranged on the n-shaped frame; bevel gears located on the two sides of the semi-conical gear are mounted on the rotating shaft; the bevel gears are meshed with the semi-conical gear; mounting shafts are arranged in the mounting cylinders; the fan blades are mounted on the mounting shafts. The dustproof heat dissipation mechanism of the invention is provided with the motor, the semi-conical gear, the bevel gears, a first belt pulley, a belt, a second belt pulley and the mounting shafts; when the fan blades rotate forwardly, air is continuously pumped into a power distribution cabinet through dust screens to perform air cooling; the fan blades rotate reversely, the air in the power distribution cabinet is pumped out, dust in the dust screens is blown to the outside of the power distribution cabinet; and therefore, the dust is prevented from entering the power distribution cabinet, a good dustproof effect is achieved, and the dust screens can be prevented frombeing blocked by more and more dust.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a dust-proof heat dissipation mechanism and a multifunctional high-voltage power distribution cabinet for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources or the use of conventional vehicle fuels, the use of new vehicle power devices, and the comprehensive vehicle power control and advanced technology in driving, forming advanced technical principles and new technologies. , The new structure of the car. [0003] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is rela...
