The invention discloses an auto-control new energy vehicle charging device. The auto-control new energy vehicle charging device comprises a pile body, a beam fixedly arranged on the upper portion of the left side of the pile body and a charging gun point. A plug-in groove is formed in the position, below the beam, of the pile body and internally provided with a conductive contact pin. A first sliding groove is formed in the end face of the bottom of the right side of the beam and internally provided with a clamping locking mechanism and a first threaded rod which is connected with the clamping locking mechanism in a screw-threaded fit mode and extends towards the left side and the right side, a first sliding cavity is formed in the position, on the right side of the beam, of the pile body, and a through groove is formed between the first sliding cavity and the first sliding groove. A first cavity is formed in the position, above the through groove, of the pipe body, a second cavity is formed in the position, above the right side of the first sliding groove, of the beam, and a second sliding groove used for penetrating through the top wall of the beam is formed in the position, above the second cavity, of the beam. A push rod arranged opposite to the left side end of the through groove is arranged on the end face of the right side of the clamping locking mechanism, and a sliding block is connected into the first sliding cavity in a sliding-fit mode. The auto-control new energy vehicle charging device is simple in structure and convenient to plug, plug-in is automatically locked, and meanwhile the intelligent prompting function is achieved.
