An anti-vibration connector for battery replacement of electric passenger car chassis

Abstract

The invention provides a vibration-proof connector for power exchange of a chassis of an electric passenger vehicle. The connector comprises a male board and a mother board; the male board and the mother board are respectively provided with a main panel and a connecting base arranged on the main panel; the male board comprises a communication safety pin, a strong current safety pin and a positioning pin which are arranged on the main panel of the male board; the mother board comprises a communication safety pin socket, a strong current safety pin socket and a positioning pin socket which are arranged on the main panel of the mother board; the communication safety pin, the strong current safety pin and the positioning pin are respectively inserted into the corresponding sockets; the male board is fixed on a battery box; the mother board is fixed on the chassis of the electric passenger vehicle; the male board and the mother board are aligned by the positioning pin. The vibration-proof connector well solves the problem of switching-off of the connector in the working process, has high reliability and is rapid and convenient to insert and pull out.

Description

technical field [0001] The invention belongs to the technical field of battery charging and swapping stations for electric vehicles, and in particular relates to an anti-vibration connector used for battery swapping of electric passenger car chassis. Background technique [0002] With the progress and development of society, traditional energy sources are getting closer and closer to exhaustion, so it is imperative to develop new energy sources, including nuclear energy, solar energy, and combustible ice, which will be the trend of future energy technology development and will also become the future The source of power for the car. The rapid development of the transportation industry is the electrification of railway transportation. After the key development of the Eleventh Five-Year Plan, the electrification level of my country's railways has exceeded 80%, and the development of electric technology in automobiles is relatively slow. With the development and progress of bat...

Problems solved by technology

A difficult problem that electric vehicles are facing now is: when the vehicle battery is exhausted, it usually takes tens of minutes for the fast charging station to fully charge the battery for a vehicle, which takes a long time and affects the continuous operation of the vehicle.

However, the connector of the quick-change battery box disconnects, catches fire during work, or loses signal failure after long-term use

The main reason is that under the condition of vibration during the driving of the car, the contact between the pin and the socket of the connector has an electrochemical reaction, and there may be a local temperature that is too high and the risk of fire and combustion may occur.
