AI Technical Summary
Traditional charging adapters have drawbacks such as the charging gun being easily pulled out, leading to a risk of electric leakage; difficulty in operating the buttons with one hand, especially for people with less strength or smaller hands; and inability to meet the required distance between the feedback column and the charging gun body.
The device employs a dual-spring automatic reset mechanism. Through the cooperation of the first and second locking mechanisms, it eliminates the travel difference between the front and rear movements of the adapter, thereby achieving automatic locking and unlocking of the charging gun, simplifying the operation process and avoiding button pressing.
It improves the safety and ease of operation during the charging process, prevents the charging gun from being forcibly pulled out, simplifies one-handed operation, and is suitable for users of different body types.
