New energy automobile charging gun head with power-off heat dissipation function

Abstract

The invention relates to the technical field of new energy vehicles, and discloses a power-off heat dissipation function. The new energy vehicle charging gun head comprises a gun body, a baffle, a first electric wire and a second electric wire, a sliding groove is formed in the side wall of the gun body, a spring is fixedly connected to the left end of the sliding groove, and a sliding plate is fixedly connected to the right end of the spring. The sliding groove and a vent hole are formed in the side wall of the gun body; the spring, the sliding plate, a magnetic plug and an electromagnetic block are arranged in the sliding groove, the baffle is arranged on the bottom side in the gun body, a thermistor is arranged on the baffle, and the magnetic force of the electromagnetic block is controlled through heat generated by long-time charging of the charging gun head under the action of the thermistor; the magnetic repulsive force of the electromagnetic block to the magnetic plug drives the magnetic plug to move to drive the sliding plate and the second wire to move, the second wire and the first wire are disconnected and powered off, and burnout of parts such as wires or electric fire caused by continuous charging due to too high temperature in the gun body is avoided.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a new energy vehicle charging gun head with power off and heat dissipation. Background technique [0002] With the improvement of people's living standards, people attach great importance to energy conservation and environmental protection. With the strong support of the state, the development of new energy electric vehicles has gradually become widespread. The use of electric vehicles is inseparable from the charging gun. The role of the charging gun is The source of power for new energy charging vehicles. [0003] In order to drive the car, the batteries used in new energy vehicles are all high-power rechargeable batteries, so when charging the car, it is also necessary to use a high-power charging gun to charge it. In the use of the charging gun, the output power of the charging gun is too large. The heating of the charging gun head will easily cause damage to the...
