Low-voltage power supply device of electric vehicle

Abstract

The invention discloses a low-voltage power supply device of an electric vehicle. The low-voltage power supply device comprises a device body. A clamp groove is formed in the top of the device body, a rotary shaft is arranged between the inner walls of two sides of the clamp groove in a connected manner, a handle is mounted on the rotary shaft and is matched with the clamp groove, grooves are vertically formed in the front side and the rear side of the device body, radiating pipes are horizontally arranged on the inner walls of the grooves, a fan is mounted on the inner wall of the side, which is far away from the device body, of each radiating pipe, a damping plate is arranged at the bottom of the device body, first spring columns are arranged between the damping plate and the device body in a connected manner, and second spring columns are arranged on two sides of the top of the damping plate. The low-voltage power supply device has the advantages that the low-voltage power supply device is reasonable in design and layout, and damage to the low-voltage power supply device due to shaking of a vehicle body in electric vehicle running procedures can be effectively reduced; heat can be radiated uniformly and comprehensively, heat radiation effects of a power supply can be improved under the condition that water is prevented from flowing into the device body, and accordingly the service life of the low-voltage power supply device can be doubly prolonged.

Description

technical field [0001] The invention relates to the technical field of power supply devices, in particular to a low-voltage power supply device for electric vehicles. Background technique [0002] Automobile power supply, also called power inverter, is a convenient power converter that can convert DC12V direct current into AC220V alternating current, which is the same as mains power, and is used by general electrical appliances. Since the advent of the car power supply, many limitations of using electrical appliances in the car will no longer exist, allowing people to truly enjoy the feeling of "traveling with home and communicating with the world". The car power supply is not only suitable for vehicle systems, as long as there is a DC12V DC power supply, a power inverter can be used to convert DC12V to AC220V AC power, which brings convenience to people's lives. The car power supply fully considers the external use environment, and will automatically protect and shut down ...

AI Technical Summary

Problems solved by technology

As the concept of energy conservation and environmental protection penetrates into people's lives, electric vehicles have become more widely and comprehensively used. On the one hand, the existing low-voltage power supply for electric vehicles is compact and inconvenient to install low-voltage batteries and high-voltage batteries at the same time. to the normal operation of high-voltage loads and low-voltage loads; on the other hand, the traditional power supply has poor heat dissipation performance, and the power supply is always in a high-load power supply state during the driving of the electric vehicle, resulting in a continuous rise in the temperature of the power supply, and the electric The car shakes after driving for a long time, which reduces the life of the power supply
