Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle charging plugs, in particular to a new energy vehicle charging plug anti-dropping device. Background Art

[0002] New energy vehicles include four major types: hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as supercapacitors, flywheels and other high-efficiency energy storage devices). The promotion of new energy vehicles is to cope with the needs of environmental protection and oil crisis, reduce or abandon the current mainstream models that burn traditional gasoline or diesel to drive internal combustion engines. The popularity of new energy vehicles is getting higher and higher. When charging traditional new energy vehicles, the charging gun and the socket of the charging pile body are friction-fitted.

[0003] Existing charging cables are usually scattered around the charging device. When someone accidentally kicks or bumps into the charging cable, it will fall off due to random touching by people coming and going, or the charging plug will be pulled off by an external object accidentally pulling the charging cable, which not only affects the charging efficiency but also causes damage to the wires. In addition, when the existing charging gun is fully charged or in danger, it cuts off the power through the internal circuit program, which has low stability and may fail. For this reason, we propose a new energy vehicle charging plug anti-detachment device. Utility Model Content
