  • Patent number: 9586490
    Abstract: A charging port structure includes a guide plate, and is configured such that a release lever of a port cap can be prevented from being exposed to water even when water has flowed into a port housing. The guide plate receives water that has flowed into a port housing from the periphery of a port lid for covering a forward opening part of the port housing so as to be capable of opening and closing. The port housing surrounds a charging port having an end connection to which a charging connector for supplying electric power from an outside power source is connected, and guides the water away from where the release lever is disposed for opening the port cap for covering the end connection of the charging port so as to be capable of opening and closing. The guide plate is disposed above the charging port.

  • Patent number: 9321363
    Abstract: An external charging structure for an electric vehicle is provided with a normal charging port to be connected with a charging gun, and a charging port lid that closes when charging is not occurring to cover an opening of a port chamber where the normal charging port is disposed and opens when charging is occurring to ensure an open space allowing a port connection with the charging gun. In the external charging structure of the electric vehicle, the charging gun has a locking part for holding a port coupling in a position of electrical connection, and an unlocking operation part placed projecting from a surface of the gun and used for unlocking by a push operation. A first-striking part is disposed on a rear surface of the charging port lid, the first-striking part coming in contact with a location other than the unlocking operation part ahead of where contact would be made with the unlocking operation part when the charging port lid is closed toward the charging gun during charging.
