Automobile charging gun with good heat dissipation effect

Abstract

The invention relates to the technical field of charging guns, and discloses an automobile charging gun with a good heat dissipation effect, the automobile charging gun comprises a charging gun shell, a first charging wire, a second charging wire and a fixed box, and movable cavities are formed in the upper and lower side walls of the charging gun shell. By designing a first charging wire, a second charging wire, a fixed box, a sliding rod, a sliding cavity and an upper moving plate, the temperature in the charging gun head is continuously increased, so that the volume of mercury in the sliding cavity is increased after heating expansion, and meanwhile, the air pressure in an air bag is gradually expanded due to the influence of temperature rise; the sliding block is propped by utilizing the expansion of mercury and an air bag to drive the sliding plate to move, and the sliding plate moves to drive the upper moving plate to move towards the right side, so that the clamping part between the first charging wire and the second charging wire is disconnected, a circuit in the charging gun is disconnected, and the situation that an automobile is continuously charged under the condition that the temperature in the charging gun rises is prevented; and the aging speed of electronic components in the charging gun is prevented from being accelerated.

Description

technical field [0001] The invention relates to the technical field of charging guns, in particular to an automobile charging gun with good heat dissipation effect. 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 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...
