A fuel filler device for filling fuel into a vehicle tank, includes a filler pipe for receiving a fuel filler nozzle, which filler pipe can be connected with the vehicle tank. At least one pivotably mounted closing flap is arranged in the filler pipe. A spring element is provided, which biases the at least one closing flap into a closing position closing a passage through the filler pipe. The at least one closing flap is pivotable from the closing position into an opening position opening a passage through the filler pipe as a result of the fuel filler nozzle inserted into the filler pipe. At least one valve element forms at least one bypass to the at least one closing flap, and from a limit pressure difference, allows a passage of gas out of the filler pipe and/or into the filler pipe.

A door lock assembly includes a housing having a hollow structure, a lifting shaft provided inside the housing, a driving spring, and a buffering device. A top end of the lifting shaft is configured for assembling a refueling or charging port flap, the lifting shaft being slidably engaged with the housing along a first portion and threadably engaged with the housing along a second portion. One end of the driving spring is fixed and the other end abuts against the lifting shaft for driving the lifting shaft to move relative to the housing. The buffering device provides a buffering function in the when the lifting shaft is threadably engaged with the housing.

Systems of an electrical vehicle and the operations thereof are provided. A powered accessory port may be utilized to selectively reveal/conceal an interior portion, such as charging connection when the powered accessory port is disposed on the exterior of a vehicle, or a user device connection, such as when the powered accessory port is disposed in the interior of the vehicle. The powered accessory port, when energized, provides a rotational force that is partially translated into a longitudinal force such that the single rotational force provides both a lifting (or lowering) motion as well as a rotational motion.

A closure of a tank of a motor vehicle for closing a filler neck gas- and fluid-tight, having a closure fastened to a flap, the flap being fastened to a vehicle body of the motor vehicle such that it is movable into an open or closed position, the closure including a seal, which causes the closure to close against the filler neck. The tank closure should be easy for a user to handle and have a relatively simple design and be economical to manufacture. This is achieved in that the seal is electromechanically or pneumatically adjustable with the aid of an actuator.

A charging flap arrangement (3) has a charging flap housing (6) which configures a recess (7) for arranging a charging plug coupling (8). The recess (7) configures the charging plug opening (5) opposite the charging plug coupling (8). The charging flap arrangement includes a charging flap (9) for closing the charging plug opening (5), an electric locking device (10) for locking the charging flap (9) which has been adjusted into a closed position, and an emergency unlocking mechanism (13) which makes opening of the charging flap (9) possible if the electric locking device (10) fails in the case of a locked charging flap (9).

Fuel charging or electricity charging port lid lock includes an elevating shaft provided with an elevating thread on an exterior wall thereof. The port lid lock also includes a worm gear configured to drive the elevating shaft. The worm gear is sleeved outside of the elevating shaft. The port lid lock also includes a worm configured to drive the worm gear. The elevating shaft is configured to be capable of moving up and moving down along an axial direction of the elevating shaft and rotating about the axial direction of the elevating shaft when driven by the worm. A head portion of the elevating shaft is used to drive a fuel charging or electricity charging port lid so as to control the opening and closing of the fuel charging or electricity charging port lid.

A fuel filler device for filling fuel into a vehicle tank, includes a filler pipe for receiving a fuel filler nozzle, which filler pipe can be connected with the vehicle tank. At least one pivotably mounted closing flap is arranged in the filler pipe. A spring element is provided, which biases the at least one closing flap into a closing position closing a passage through the filler pipe. The at least one closing flap is pivotable from the closing position into an opening position opening a passage through the filler pipe as a result of the fuel filler nozzle inserted into the filler pipe. At least one valve element forms at least one bypass to the at least one closing flap, and from a limit pressure difference, allows a passage of gas out of the filler pipe and/or into the filler pipe.

An opening and closing device (10), such as for a charging port on electric vehicles or a fuel filler neck on vehicles with a combustion engine, has a flap unit (68), an actuator (30) for moving the flap unit (68), and a housing (16). The flap unit (68) has at least one guide element (114) which engages in a guide slot (126, 130) formed in the housing (16). The flap unit (68) is coupled to a cross-piece or traverse that can be moved by the actuator by means of at least one coupling element.

A forward/backward movement device includes: a case; a guide member that is housed in the case and includes a shaft and a protrusion formed on an outer peripheral surface of the shaft; and a forward/backward movement member having a cylindrical shape. The forward/backward movement member includes a groove that is formed on an inner peripheral surface of the forward/backward movement member and moves forward and backward with respect to the case while rotating by being guided by the protrusion. The groove is a portion where the protrusion slides. Thereby the forward/backward movement device can be miniaturized while preventing the intrusion of water.
