Anti-explosion power supply device of electric vehicle

Abstract

The invention discloses an anti-explosion power supply device of an electric vehicle. The anti-explosion power supply device comprises a power supply box body (1), a box cover (1), a storage battery (8), a connection box (3) and a charging socket assembly (4), wherein a main power supply switch (6) is connected with the connection box (3); the charging socket assembly (4) is hinged with a socket cover plate (5) capable of separating the outside; a first electromechanical interlocking device is arranged between the main power supply switch (6) and the socket cover plate (5); a second electromechanical interlocking device is arranged between the charging socket assembly (4) and the storage battery (8). By using the structure, the phenomenon that the charging socket is charged when the charging socket is not charged or the main power supply switch is turned off can be avoided, so that the safety performance is greatly improved.

Description

technical field [0001] The invention relates to the technical field of explosion-proof power supplies, in particular to an explosion-proof power supply device for electric vehicles for explosion-proof electric vehicles in hazardous environments with explosive gases I and II and environments with combustible dust. Background technique [0002] With the development of mechanical modernization, industrial electric vehicles are widely used in many places such as cargo handling, loading and unloading, stacking, etc., saving time and effort, and greatly improving production efficiency. However, in some dangerous environments with explosive gas and combustible dust, the explosion-proof performance of the vehicle is particularly important. Therefore, the safety of the explosion-proof power supply device of the explosion-proof vehicle is also a key technology. The explosion-proof power supply device in the prior art generally includes a power supply box, a box cover and a lead-acid b...

AI Technical Summary

Problems solved by technology

The above existing technologies are not considered from the direction of sealing, or from the direction of ventilation, and have not fundamentally solved the potential safety hazards of the power supply device itself.

This is because the battery is connected to the vehicle power supply joint installed in the junction box on the outer wall of the power supply box, and is connected to the charging socket for charging the battery at the same time, therefore, the power supply device supplies power (in a non-charging state at this time) At this time, the entire junction box and charging socket are charged; in addition, even when the main switch of the power supply is turned off, the charging socket connected to the battery is still charged; therefore, the entire power supply device has potential safety hazards.
