A charging flap system for electrically propelled vehicles has a charging socket bracket and a charging socket fastened therein having an outer wall, an inner wall and a cavity therebetween, including a DC power connection, and a charging flap, which is connected for rotation via an articulation joint with a return spring to the charging socket bracket and covers the DC power connection in a first position and reveals the power connection in a second position. An undercut is arranged on the articulation joint. A retaining hook has a socket pin, the bottom of which can be displaced on the charging socket bracket and which includes a tip which points towards the DC power connection. The retaining hook has a joint pin, which is connected to an end region opposite the tip and leads away from the charging socket bracket at a predefined angle, wherein the free end of the joint pin has a retaining lug matching the undercut. A spring is arranged on the joint pin such that the joint pin is pressed towards the charging socket. A recess is arranged in the outer wall of the charging socket such that the tip of the socket pin can be guided through the recess. The undercut of the articulation joint and the retaining hook are arranged such that, in the closed state of the charging socket cover, the retaining lug bears on a region of the articulation joint, which does not have an undercut, such that the tip of the socket pin extends through the outer wall but not into the cavity, and, in the opened state of the charging socket cover, the undercut is arranged such that the retaining lug engages in the undercut and the tip of the socket pin extends into the cavity.

Charging flap system for electrically propelled vehicles

A charging housing or filler neck housing for insertion into a body opening in a motor vehicle comprises a housing body with a passage opening. A plug-in charging connector or a tank filler pipe can be inserted into the passage opening, and a sealing ring is arranged on the passage opening. The sealing ring has an annular sealing body, from which a first elastic sealing lip and a second elastic sealing lip extend, wherein the first sealing lip is designed to bear against a plug-in charging connector or tank filler pipe inserted into the passage opening, and wherein the second sealing lip is designed to bear against a closure flap closing the filler neck housing or charging housing.
