Technical Field

[0001] The utility model relates to the technical field of charging guns, and in particular to a new energy charging gun which is easy to plug and unplug. Background Art

[0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen-powered vehicles and solar vehicles. Their exhaust emissions are relatively low. Because of their green and environmental protection, they are increasingly accepted and liked by the majority of users. New energy vehicles have therefore developed rapidly. During use, they need to be charged by the charging gun of the charging terminal. The new energy vehicle charging guns currently on the market can basically meet the charging needs of various new energy vehicles. However, when charging new energy vehicles with existing charging guns, people often need a lot of force to plug and unplug the charging interface. Due to long-term wear, the car charging interface may become loose, resulting in poor contact in the later stage, affecting the charging efficiency.

[0003] The prior art patent (CN210926498U) discloses a charging gun for new energy vehicles that is easy to plug and unplug, including a charging gun body, a handle, a charging cable, and a protective cover. A vacuum generator is fixedly installed on the lower side of the charging gun body, and a mounting ring is fixedly installed on one side of the vacuum generator gun head. Small motors are fixedly installed at the angles on both sides of the mounting ring and the vacuum generator. The rotating shaft of the small motor passes through the mounting ring, and a welding machine screw rod is welded at one end of the rotating shaft. The screw rod is threadedly connected to a threaded barrel, and a vacuum suction cup is fixedly connected to one end of the threaded barrel. A retractable air pipe is connected to one side of the vacuum suction cup, and the retractable air pipe is connected to the vacuum generator. The user does not need to exert much effort throughout the whole process. He only needs to align the charging gun plug with the car charging port and press the switch to complete the charging and plugging. It is practical and convenient, and will not wear the charging port and is low in cost.

[0004] However, in the aforementioned prior art, since no protective structure is provided in the device, the charging gun is easily damaged, thereby reducing the service life of the charging gun. Utility Model Content

The gun head is inserted into the circular protective block and the rubber block is squeezed and contracted to deform. When it is inserted into the appropriate position, the elastic action of the contracted rubber block enters the interior of the square groove to clamp and fix it, which has a protective effect on the gun head. Therefore, the charging gun body can be protected and the service life of the charging gun body can be increased. BRIEF DESCRIPTION OF THE DRAWINGS
