Description

Technical Field

[0001] The present invention relates to the technical field of charging guns, and in particular to a locking mechanism for a charging gun for a new energy vehicle. Background Art

[0002] A new energy vehicle charging gun is a special device used to transfer electrical energy from a power source to the battery of an electric vehicle. It consists of a plug, a cable, and a controller. The plug is connected to the power source, the cable transfers the electrical energy to the electric vehicle, and the controller monitors and regulates parameters such as current, voltage, and time during the charging process to ensure the safety and reliability of charging. There are many types of new energy vehicle charging guns, the most common of which are AC charging guns and DC charging guns.

[0003] After searching, the publication (announcement) number: CN220332484U discloses a new energy vehicle charging gun, including a connecting cavity, a protective cold air cavity is fixedly installed on one side of the top of the connecting cavity, a protective cold air chamber is nested and connected inside the protective cold air chamber, an isolation plate is provided on one side of the interior of the protective cold air chamber, a battery is overlapped on the top of the isolation plate surface, a guide rod is connected to one side of the battery, a guide rod is connected to one side of the battery, a cooling fan is movably connected to one side of the guide rod, a filter exhaust port is provided at one end of the cooling fan, and a charging gun body is nested inside the protective cold air chamber. When the charging gun body is in the charging process, the present invention is fixed by connecting the cavity for transfer, and the outer wall of the charging gun body is cooled by the cooling fan provided inside the protective cold air cavity, which can reduce the high temperature environment while reducing the heat of the gun body itself, thereby facilitating the reduction of temperature restrictions, and further reducing the wear and burning of its power components by high temperature, thereby maintaining its service life.

[0004] In the above-mentioned prior art solution, there is no locking structure, and charging is performed by plugging the connector into the charging base. Since the charging gun itself does not have a locking structure, it is easy to be accidentally unplugged during the charging process, affecting the subsequent charging, thereby reducing the use effect.

[0005] To this end, we propose a locking mechanism for a charging gun for a new energy vehicle. Summary of the invention
