Low-voltage control box for new energy automobile

Abstract

The invention discloses a low-voltage control box for a new energy automobile. The low-voltage control box structurally comprises a radiator, a radiating plate, a base, a shell, a data interface, a sensor interface, a laminated capacitor, a control power panel, a driving module and a fastening bolt, wherein the radiator is fixedly arranged below the radiating plate, and interference fit is adopted; the base is mounted above the radiating plate, and bolted connection is adopted; the base is mounted below the shell, and buckled connection is adopted; the data interface is mounted on the right side of the sensor interface, and signal connection is adopted between pins of the data interface and pins of the sensor interface. The radiator is provided with a coil, a rotating shaft, a permanent magnet, fan blades and a frame body, the radiator of the improved low-voltage control box for the new energy automobile in the prior art is additionally arranged outside, the temperature of the controller is reduced through the cooperation with radiating fins, and the problem of electric appliance fault caused by condensed water vapor when the temperature of main board components is reduced once theautomobile is turned off cannot appear.

Description

technical field [0001] The invention is a low-voltage control box for a new energy vehicle, which belongs to the technical field of low-voltage control box equipment. Background technique [0002] The electric vehicle controller is the core control device used to control the start, operation, advance and retreat, speed, stop and other electronic devices of the electric vehicle motor. It is like the brain of the electric vehicle and an important part of the electric vehicle. At present, electric vehicles mainly include electric bicycles, electric two-wheeled motorcycles, electric tricycles, electric three-wheeled motorcycles, electric four-wheeled vehicles, battery cars, etc. Electric vehicle controllers also have different performance and characteristics due to different models. . [0003] However, in the prior art, some low-voltage control box radiators for new energy vehicles are installed inside the housing. Once the temperature of the main board original is lowered once...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a low-voltage control box for new energy vehicles to solve the problem that some radiators of the low-voltage control box for new energy vehicles in the prior art are installed inside the housing. It is also a general problem to reduce the condensed water vapor to cause electrical failure, or to choose an integrated aluminum shell for heat dissipation.
