Abstract

A charging connection device of this type, comprising a vehicle-mounted charging recess in its ready-to-use state, which surrounds a charging connection, and a closing flap which is displaceable relative to the charging recess between a closed position and an open position, wherein the closing flap has a flap carrier and a cover held on the outside of the flap carrier, and a drive system which drives the closing flap for an opening movement in the direction of the opening position and/or for a closing movement in the direction of the closed position, wherein the drive system has a switching arrangement that can be activated by a movement of the closing flap, is known. According to the invention, the aperture is mounted with limited movement relative to the flap carrier, and in the closed position of the closing flap, the aperture and the switching arrangement are spatially related to each other in such a way that a movement of the aperture leads to a mechanical contact with the switching arrangement, which triggers an activation of the switching arrangement.

Description

The invention relates to a charging connection device for a motor vehicle according to the preamble of claim 1. Such a charging port device is made from the DE 10 2022 135 079 A1 The known charging port device has a vehicle-mounted charging recess surrounding a charging port. A closing flap is guided on the charging recess and is movable between a closed and an open position. The closing flap is formed by a flap carrier and a cover plate held on the outside of the flap carrier. A drive system is provided for moving the closing flap, which has a switching arrangement that can be activated by movement of the closing flap. The cover plate is adjustably mounted on the flap carrier such that it can be partially moved from a rest position to an active position in order to trigger a sensor signal from a sensor unit. The DE 10 2022 102 402 A1 discloses a fuel filler flap arrangement in which a fuel filler flap can be locked by means of a push-push mechanism or released for a pivoting movement. Another charging port device is from the DE 10 2022 209 940 A1 The known charging port device is designed to provide access to an electric charging port of a motor vehicle. A charging recess is provided in a cutout in a vehicle body. The charging recess encloses an electric charging port. The charging recess can be closed by a flap, which is movably mounted on the vehicle side of the charging recess between an open position (releasing the charging recess) and a closed position (closing the charging recess). An electric drive system is provided for moving the flap between the closed and open positions, which can be activated by means of a switch assembly. The switch assembly is designed as a movable switching element and is fixed to the vehicle in the area of the charging recess. The flap has an integrally molded actuating finger that interacts with the movable switching element. The flap consists of a flap carrier and an externally positioned cover plate, with the actuating finger being integrally molded onto the flap carrier. The cover plate is fixedly connected to the flap carrier. The object of the invention is to create a charging connection device of the type mentioned above which enables a reliable opening or closing process of the closing flap, independent of temperature. This problem is solved by the features of claim 1. According to the invention, to open the closing flap from the outside, pressure is manually applied to the flap's cover in its closed position, thereby activating the switching arrangement, which transmits a corresponding signal to the drive system to actuate the closing flap for an opening movement. Because only the cover needs to be moved manually, the operating forces required by an operator are significantly reduced compared to the prior art. Since the cover is relatively lightweight compared to the entire closing flap, comparatively small operating forces are sufficient to activate the switching arrangement. The cover can be applied externally at various positions distributed across its surface without a significant increase in the operating forces. Furthermore, the operating forces remain essentially constant regardless of ambient temperature. Advantageously, the operating force required by an operator remains at least largely constant over a wide temperature range, from very low to very high temperatures. The flap carrier itself is not moved during this actuation and remains in the closed position, in which it rests on an edge of the loading recess. The solution according to the invention is suitable for all types of motor vehicles. It is particularly advantageous for motor vehicles with electric charging ports, preferably for passenger cars. An electric charging port is used to charge a vehicle battery that powers the vehicle's drive system. Electricity is supplied to the charging port of the charging device via a charging cable from a stationary charging station. Alternatively, the solution according to the invention can also be used for motor vehicles where energy is charged in the form of fuel by inserting a refueling nozzle into a charging port in the form of a vehicle-side fuel filler neck. Here, too, the loading flap can be moved from the closed position to the open position by means of a drive system. According to the invention, the aperture projects laterally at least partially beyond an edge region of the flap carrier, and the switching arrangement is arranged laterally on the loading trough in such a way that the switching arrangement projects into a movement area of the aperture section projecting laterally outwards beyond the edge region of the flap carrier – to the closed position of the The invention relates to the closing flap. This flap section can be provided with an integrally molded or fixedly arranged actuating extension, preferably in the form of an actuating finger. When pressure is applied to the flap from the outside, the actuating extension mechanically comes into cont
