Abstract

The invention relates to the technical field of new energy, and discloses a heat-dissipating and power-off safe charging gun, which comprises a charging gun shell, a first charging wire, a second charging wire and a charging head, sliding cavities are formed in the middle parts of the upper and lower side walls of the charging gun shell, and the upper and lower side walls of the sliding cavities are fixedly connected with resistance layers; and a sliding contact is connected between the resistance layers in a sliding manner. By designing the first charging wire, the second charging wire, the sliding cavity, a magnetic sliding plate and an electromagnetic block, an air bag in the sliding cavity is heated and expanded through heat generated when the charging gun is used, and a sliding contact is driven to move through expansion of the air bag, so that the resistance value of a resistance layer is reduced; therefore, the current needed by the electromagnetic block is controlled to increase to promote the magnetic force of the electromagnetic block to increase, the electromagnetic block attracts the magnetic sliding plate to move, the first charging wire and the second charging wire are disconnected, and the situation that when the interior of the charging gun is seriously heated, an automobile is still charged, and electronic elements in the charging gun are damaged is avoided.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a safe charging gun capable of dissipating heat and cutting off power. Background technique [0002] With the development of society, people pay more and more attention to environmental protection. With the improvement of living standards, automobiles have become one of the main ways of travel for people. Due to the impact of automobile exhaust on the environment, it also promotes the development and use of electric vehicles. The driving power of electric vehicles all comes from electric drive, so there will be no harmful auxiliary substances such as carbon monoxide and nitrogen oxides produced when fuel vehicles are used, and the use of electric vehicles will basically not pollute the environment. [0003] In the use of electric vehicles, the battery on the vehicle is mainly charged through the charging gun, so that the vehicle has kinetic energy, which is convenient for the ...
