A charging pile that is automatically disconnected and retracted after charging

Abstract

The invention discloses a charging pile capable of being automatically disconnected and withdrawn after charging is completed, which comprises acharging pile.Awire cavity is formed in the charging pile; the right side of the wire cavity communicates with an annular contact cavity; a wire rotating wheel shaft extending leftwards into the wire cavity is connected into the right end wall of the annular contact cavity in a rotating fit mode. Power is supplied through abutting of thewire and the annular contact. The wire and the charging box can be withdrawn by rotating awire turntable; the wire isprevented from being exposed outside to cause aging or stumbling a user; when the charging box is pulled out, apower torsional spring is twisted to store power; power is provided for subsequent automatic separation of the charging box, the power source is thus reduced, and the cost is reduced; and after charging is completed, the charging box is automatically separated and reset under the actionof wire tension, so that the situation that the charging head is left in the charging port for a long time when an automobile owner is not in place is avoided, meanwhile, when the charging box is separated, abaffle is reset, the automobile charging port cover can be automatically closed, and rainwater infiltration is avoided.

Description

technical field [0001] The invention relates to the related technical field of charging piles, in particular to a charging pile that is automatically disconnected and retracted after charging. Background technique [0002] With the popularity of electric vehicles, a large number of charging piles have also begun to be installed. Due to the relatively long charging time at present, some car owners will leave the parking space when charging. Many car owners mistakenly believe that the charging pile is in use. At the same time, the long-term exposure of the charging gun and wires will easily lead to the aging of the outer rubber layer. On the other hand, most of the current charging gun wires do not have the function of automatic retraction. There is a possibility of being run over by a car, damaging the user or tripping the user, which poses a certain safety hazard. Contents of the invention [0003] In view of the deficiencies of the above-mentioned technologies, the prese...
