Description

Technical Field

[0001] The utility model belongs to the field of new energy vehicles, and specifically relates to a charging gun for new energy vehicles. Background Art

[0002] Since the beginning of the 21st century, my country's electric vehicle industry has experienced rapid growth. Demand for charging stations in places like homes and underground parking lots has also rapidly increased. However, due to design deficiencies, charging gun damage and safety hazards are common. For example, charging guns are often placed by inserting them into charging stations or hanging them with wires, which can easily cause them to fall off, get run over, and be damaged. Common placement methods for inserting charging stations are horizontal and lack locking holes, making them prone to falling off. Horizontal placement also requires more space and, in certain environments, is prone to frost, snow, dust, and water accumulation, posing serious safety risks. Furthermore, charging stations like homes and underground parking lots are often dark, making it difficult to find the charging port and align the charging gun with the vehicle socket.
