Description

Technical Field

[0001] This utility model relates to an electronic lock for a charging dock and a charging dock including the electronic lock. Background Technology

[0002] In existing technology, charging docks for new energy vehicles typically include a housing, a mounting bracket, terminals, and an electronic lock. The terminals are housed within the housing, and the housing and electronic lock are fixed to the mounting bracket. The housing has a mating port suitable for mating with a charging gun, and the mounting bracket has a mating socket allowing the charging gun to be inserted. The mating port of the housing mates with the mating socket of the mounting bracket. The terminals extend into the mating port for mating with the mating terminals of the inserted charging gun. The electronic lock has a retractable locking lever, and a locking lever hole is formed on the peripheral wall of the mating socket of the mounting bracket to allow the locking lever to pass through. When the charging gun is mated with the charging dock, the locking lever extends and engages with a pin hole on the charging gun to lock the charging gun to the charging dock, preventing accidental detachment of the charging gun from the charging dock.

[0003] In existing technology, rainwater or washing water can easily enter the mating port and mating socket of the charging dock. To drain water from the mating port, a water pipe connector is usually formed on the peripheral wall of the mating port of the housing, communicating with the interior of the mating port. This allows water in the mating port to be drained to the outside of the vehicle in a timely manner through a drain pipe connected to the water pipe connector. However, the locking rod hole and locking rod on the mounting bracket have a clearance fit, allowing water in the mating socket to flow directly into the interior of the vehicle through the locking rod hole, causing dampness inside the vehicle.
