A fuel lid opener-has: a heart cam mechanism that is structured so as to, each time a lifter is push-operated via a fuel lid, cause the lifter to alternately repeat advancing-out and withdrawing, and so as to push the fuel lid open due to advancing-out of the lifter; and a locking mechanism-that can restrict operation of the heart cam mechanism. At the locking mechanism, a time when a stopper is moved by operation of a motor, and the aforementioned restricting is released, the aforementioned stopper engages with the heart cam mechanism and operates the heart cam mechanism. Due thereto, the lifter advances-out, and the fuel lid is pushed open.

An actuating device for a movable part, in particular a cover of a vehicle body opening, including at least one actuator and at least one electromechanical switching element. The electromechanical switching element is changeable between a first mode and a second mode. In the first mode, the electromechanical switching element senses an actuation by the actuator and in the second mode, the electromechanical switching element releases the actuator such that the actuator can be moved toward the movable part. The electromechanical switching element has an electroactive polymer and/or a piezoelectric element.

A closing device includes a box with a hole, a roto-translating pin disposed in the hole of the box in such a way to rotate and translate from a retracted closing position to an extracted opening position. The closing device has a spring to push the roto-translating pin in the opening position, a locking device to lock the roto-translating pin in the closing position, a first actuator to move the locking device, a second actuator to move the first actuator. The roto-translating pin has a shoulder that protrudes externally from the roto-translating pin to be stopped against the internal wall of the box around the hole in such manner to stop the extraction travel of the roto-translating pin.

A cover apparatus for a motor vehicle body has a movement device (5) with first and second guide rails (8, 9) that are spaced from one another and received rigidly on the motor vehicle body (2). A covering element (4) covers a filling connector (7) of the motor vehicle body (2) and is received movably on the motor vehicle body (2). The covering element (4) is coupled to the first and second guide rails (8, 9). A third guide rail (10) is transverse to the first and second guide rails (8, 9). The third guide rail (10) is configured to be movable relative to the motor vehicle body (2) and the first and second guide rails (8, 9). The third guide rail (10) is configured to receive the covering element (4), and the covering element can be moved relative to the third guide rail.

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.

An actuating device for opening and closing a cover in or on a vehicle includes a housing, a rotatable plunger, a spring that preloads the plunger into a discharge position, and an actuating sleeve into which the plunger can be introduced. At least one actuating groove extends helically around the longitudinal axis of the actuating sleeve and is formed on the inside of the sleeve. At least one actuating projection of the plunger engages into the actuating groove when the plunger is introduced into the actuating sleeve causing the plunger to rotate about its longitudinal axis during an axial relative movement between the actuating sleeve and the plunger. A blocking device blocks plunger movement into the discharge position to hold the plunger in a locked position. A spring element preloads the blocking device into a blocking position, and an actuator disengages the blocking device from the blocking position.

An actuating apparatus for opening and closing a cover in or on a vehicle has a blocking device for blocking the cover in a locked position. The blocking device has a transmission mechanism with a rotation part (64.1; 50) mounted rotatably and driveable by an actuator (34), and a blocking bar (62) which is operatively connected to the rotation part. The transmission mechanism converts a rotation movement of the rotation part into an axial movement of the blocking bar. The blocking bar is transferable with the aid of the rotation part from a release position into a blocking position. The transmission mechanism is self-locking so that, at least whenever the blocking bar is in the blocking position, the rotation part is not driveable via an axial movement of the blocking bar, and the rotation part prevents an axial movement of the blocking bar out of the blocking position.

A motor vehicle has at least one pressure vessel for storing storage medium, preferably fuel, at least one pressure relief device for pressure relief of the at least one pressure vessel, and at least one opening through which storage medium flows out during a pressure relief.

A lock pin is arranged so as to be projected from a side wall of a concave region, in which a fuel filler port of a vehicle is arranged, toward the inside of the concave region. In addition, a retainer placed around the lock pin on an inner side of the side wall of the concave region and a protector supported by the retainer so as to be placed in a region close to the lock pin are provided. The protector has a detent pin to prevent the retainer from rotating relative to the lock pin.

A sealing device for sealing a through opening in a vehicle chassis includes a sealing element that can be shifted between an open position, in which the through opening is released, and a closed position, in which the through opening can be closed. The sealing device has an adjusting device which includes a guide housing that can be arranged in a spatially fixed manner on the vehicle chassis, in which guide housing a carrier element is translationally and pivotably guided, where the carrier element has the sealing element. A slide guide is provided, via which the carrier element can be translationally shifted and pivoted in relation to the guide housing. A traction element is translationally entrainably connected to the carrier element, and simultaneously connected in a rotationally decoupled manner, via a pivot bearing. The traction element is translationally shiftable by the drive.
