New energy automobile charging interface safe in power supply and charging device

Abstract

The invention discloses a new energy automobile charging interface safe in power supply and a charging device. The charging device comprises a charging pile and the automobile interface. A take-up cavity is formed in the charging pile. An operating groove is formed in the outer end face, on the right side of the take-up cavity, of the charging pile. A through hole is formed between the operating groove and the take-up cavity. A first sliding groove with the top communicating with the take-up cavity is longitudinally formed in the inner bottom wall of the right side of the take-up cavity. A second sliding groove is transversely formed in the middle of the first sliding groove in a penetrating mode and communicates with the first sliding groove. A rotating shaft is longitudinally arranged in the take-up cavity. The top of the rotating shaft is connected with a take-up motor in a power fit mode. A take-up reel is fixedly and circumferentially arranged on the rotating shaft. A charging line is wound on the take-up reel. A charging gun is arranged in the operating groove. A plug used for being in plugging fit with the through hole is arranged on the left side end face of the charging gun. The left side end face of the plug is fixedly connected with the charging line. A connecting block is arranged in the charging gun. A protruding block is arranged on the right side end face of the connecting block. The charging device is simple in structure, convenient to operate, stable in connection and high in safety.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle charging, in particular to a new energy vehicle charging interface and a charging device for safe power supply. Background technique [0002] With the emergence of electric vehicles, the use of charging piles for electric vehicles has increased. When users use the existing electric vehicle charging piles to charge electric vehicles, they plug the charging plug directly into the socket for charging. If it is loose, there will be poor contact, and because there is a large current flowing through the socket, the charging plug is easily damaged. When the charging pile is charging the electric vehicle, pulling out the charging gun will cause a safety accident, causing casualties, If the device is damaged or even causes a fire, in order to avoid safety accidents, it is necessary to lock the charging gun during the charging process and unlock it after charging; if the power is cut off during t...

[0002] With the emergence of electric vehicles, the use of charging piles for electric vehicles has increased. When users use the existing electric vehicle charging piles to charge electric vehicles, they plug the charging plug directly into the socket for charging. If it is loose, there will be poor contact, and because there is a large current flowing through the socket, the charging plug is easily damaged. When the charging pile is charging the electric vehicle, pulling out the charging gun will cause a safety accident, causing casualties, If the device is damaged or even causes a fire, in order to avoid safety accidents, it is necessary to lock the charging gun during the charging process and unlock it after charging; if the power is cut off during the charging process, the charging gun cannot be pulled out, and manual unlocking requires charging Pile maintenance personnel operate, which brings inconvenience to the actual application. In addition, the existing charging pile automatic charging line, the user often does not place the charging line as required after use, but throws the charging line on the ground at will; in this way, the charging line is easy to use. Various unexpected stresses, such as trampling by people, rolling over by cars, etc., will cause damage to the outer insulation of the charging line, resulting in a decrease in the life of the charging line, resulting in electric shock accidents
