Battery protection equipment for preventing charging head of new energy automobile from being fused

Abstract

The invention relates to the technical field of whole vehicle manufacturing of new energy vehicles, and discloses battery protection equipment for preventing a charging head of a new energy vehicle from being fused. The exterior of a main body is fixedly connected with an air spring. According to the battery protection equipment for preventing the charging head of the new energy automobile from being fused, due to the fact that a rubber block cannot provide enough bearing force for the load of an air spring, the air spring expands to extrude a rubber block, the rubber block extrudes a mounting frame to synchronously move towards the middle, and cold air in a telescopic bag is extruded out; the gas enters a thermometer through a central tube and moves downwards under the power-off action of a power-off strip; the left end and the right end of the power-off strip are a positive electrode and a negative electrode respectively, the power-off strip is made of a rubber material, and electric quantity is guided out; and the gas finally enters a metal part, and the cooled gas in the metal part is stored and detected, so the situation that a gun head is heated and fused due to the fact that equipment cannot be cooled in time due to high temperature is prevented.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle manufacturing, in particular to a battery protection device for preventing melting of a charging head of a new energy vehicle. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four types Hybrid electric vehicles, pure electric vehicles, including solar vehicles, fuel cell electric vehicles, and other new energy sources, among which new energy charging guns are essential. [0003] However, in the traditional new energy vehicle equipment, the traditional car charging gun often does not have the function of temperature testing and protection.

Problems solved by technology

[0003] However, in the traditional new energy vehicle equipment, the traditional car charging gun often does not have the function of temperature testing and protection. The charging tip part is prone to failure, and it is easy to continue to use it frequently even when the temperature is high. It makes the tip of the gun hot or even melted, and there is no way to cut off the power. It is very dangerous for new energy vehicles. Not only that, after the charging gun is automatically powered off, some internal wires are still connected, and a certain amount of power will still be lost. , when an overvoltage occurs in the wire, it will cause damage to the car battery, so a new energy car charging head to prevent battery protection equipment from melting came into being
