Various types of vehicle hatches with opening and closing devices are known. In the field of electromobility, for example, there is frequent charging of traction batteries at charging stations where vehicles use various standardized connectors and

• - loading cans is required. In order to prevent the high-voltage connections from getting dirty and from contact with moisture or water, the charging sockets of the vehicles are covered and sealed at least when the vehicle is in motion. For charging, the covers are opened and the mating connector can be connected to the charging station. The preferred automatic opening of the vehicle flap, also known as the loading flap, on the vehicle is an important comfort feature. In order to avoid damage to the flap or the outer contour of vehicles, it is advantageous to avoid interfering edges with vehicle flaps. The vehicle flaps preferably close flush with the outer contour of the vehicle or are flush with it in the closed state. Furthermore, the vehicle flaps seal with the outer contour of vehicles.

A vehicle hatch of this type is off DE 10 2010 053 137 A1 known. A charging interface for a motor vehicle for charging the traction battery with a charging socket arranged in a body opening and a closure device covering the body opening comprises a charging socket that can be displaced in the axial direction of the body opening and that opening the closure device causes the charging socket to move. In the open state, the locking device, also called the cover, protrudes from the outer contour of vehicles.

DE 10 2018 128 972 A1 discloses a flap having an opening mechanism having first and second guides. A guide pin fastened to an inside of the flap is mounted in or on the guides, which guide pin can be moved in reverse along a trajectory predetermined by the corresponding guide between a first end point and a second end point. The flap can thus be moved between a closed position and an open position and vice versa. When open, the flap protrudes from the outer contour of vehicles.

Out DE 196 42 687 A1 a locking device for securing a charging socket is known. In this case, a swivel cover can be locked in a securing position, the securing position corresponding to a defined open position in which the swiveling cover can act as a blocking effect against the removal of an inserted charging plug.

The invention is based on the object of improving a vehicle flap of the type mentioned at the outset in such a way that the opening and closing of the vehicle flap can be implemented automatically on a vehicle and damage or injuries to or through the vehicle flap are avoided in the open state.

The object is achieved according to the invention by the design features of claim 1.
Further developments result from the dependent claims.

A first advantage of the vehicle flap is that this vehicle flap comprises an opening and closing device which can automatically expose or close an opening in a vehicle contour, e.g. a body, and that an interface is provided within this opening which is related to the vehicle contour in Set back towards the interior of the vehicle, is arranged in a stationary manner on the vehicle.
Such an interface can be a charging module (charging socket) for an electric or hybrid vehicle. Alternatively, the interface can be an opening for receiving gaseous or liquid fuels or for oil or for comparable media.

A second advantage arises from the fact that the opening and closing device comprises a sliding and pivoting device connected to the vehicle flap, and the sliding and pivoting device is coupled to a gear, preferably a toothed gear. The transmission is connected to an actuator by means of a shaft or, alternatively, by means of a transmission coupling. The controllable actuator can preferably be connected to control electronics of the vehicle in terms of circuitry and signaling. The control electronics can advantageously be activated by means of a proximity sensor, radio key, smartphone, etc., so that the opening and closing process of the vehicle flap can be implemented in an automated manner. In a further embodiment, the actuator can be activated manually.

A third advantage is that by means of the drivable sliding and pivoting device, a sliding movement of the vehicle flap in the direction of the vehicle interior or vice versa in the direction of the vehicle contour, e.g. the outer contour of the body, can be implemented and that a pivoting movement of the vehicle flap is also possible by means of the drivable sliding and pivoting device around a Axis, for example the shaft, can be realized, in which case the vehicle flap can be set back to the vehicle contour inside the vehicle and can be moved back into an open position or vice versa in the direction of a closed position (intermediate position).

The advantage here is that the vehicle flap can always be moved inside the vehicle with regard to the sequence of movements, i.e. set back from the vehicle contour. In this way, in every phase of movement of the vehicle flap, possible parts or interfering edges protruding from the vehicle contour (body) can be avoided. Damage or injuries to or from the vehicle flap when it is open can be avoided. When handling charging cables, plug-in systems, dispensing devices, etc., the interface is always easily accessible when open.

In the closed position, the vehicle flap is aligned with the vehicle contour and closes the opening. The opening advantageously comprises a seal against which the vehicle flap rests tightly from the inside in the closed position. When the vehicle flap is opened, the pressure on the seal can also be relieved by the sliding movement of the vehicle flap in the direction of the vehicle interior.

Another advantage is that the opening and closing device of the vehicle flap - with reference to a vehicle floor - can be arranged, for example, horizontally, vertically or at any desired angle inside the vehicle. Depending on the space available in the vehicle interior, the vehicle flap can thus be moved upwards, downwards or sideways in the vehicle interior for the purpose of realizing the pivoting movement - with reference to the vehicle floor. The operating principle is always maintained in that a sliding movement of the vehicle flap in the direction of the vehicle interior or vice versa in the direction of the vehicle contour can be implemented by means of a drivable sliding and pivoting device and a pivoting movement of the vehicle flap around the axis can be implemented by means of the drivable sliding and pivoting device, with the vehicle flap set back to the vehicle contour in the vehicle interior is pivotable and movable into an open position or, conversely, can be moved back in the direction of a closed position.

• 2 die Fahrzeugklappe mit Bezug zur Schließstellung in linear zurückgesetzter Position (Zwischenposition)
• 3 die Fahrzeugklappe in Öffnungsstellung.

The invention is to be explained in more detail using an exemplary embodiment. The present example relates to a vehicle flap which, in addition to a linear sliding movement, realizes a pivoting movement - with reference to the vehicle floor - upwards within the vehicle interior. They show schematically:

• 1 a vehicle flap with opening and closing device in the closed position, aligned with the vehicle contour
• 2 the vehicle flap in relation to the closed position in a linearly recessed position (intermediate position)
• 3 the vehicle flap in the open position.

A vehicle includes a vehicle door 1 with opening and closing device, with an opening in a vehicle contour by means of the opening and closing device 17th , for example a body, can be exposed or closed and an interface within this opening 14th is provided which is related to the vehicle contour 17th is set back in the vehicle interior, fixed to the vehicle. Such an interface 14th can be a charging module (charging socket) for an electric - or be a hybrid vehicle. Alternatively, the interface 14th an opening for receiving gaseous or liquid fuels or for oil or for comparable media.

The opening and closing device includes one with the vehicle door 1 connected sliding and swiveling device 2 , 3 , 4th , which at least one holding arm 3 and at least a guide 4th having.

The present example shows two holding arms arranged in parallel 3 , which with the vehicle flap 1 are firmly connected and each has its own guide 4th are arranged. The guides 4th are by means of a shaft 9 connected as an intermediate shaft on the drive side. Alternatively, this can also be done by means of a transmission coupling of an intermediate gear. Each holding arm 3 each has a front cam 12th on. The respective front cam 12th is along a stationary guide rail 19th movable so that a sliding movement (linear movement) 15th of the front cam 12th allows a pivoting movement 16 around an axis 5 in the area of the guide rail 19th is prevented.

The sliding and swiveling device 2 to 4th is with at least one gear transmission 6th , 7th , 8th coupled and the gear transmission 6th to 8th is equipped with an actuator that can be reversed with regard to the direction of rotation 10 by means of the shaft 9 (or the gearbox coupling) connected. Each holding arm 3 has a stop 18th on which the sliding movement (linear movement) 15th limited in a first direction. Furthermore, each holding arm 3 a lock 11 on which the sliding movement (linear movement) 15th limited in the opposite, second direction.
By means of the drivable sliding and swiveling device 2 to 4th is the sliding movement 15th the Vehicle flap 1 in the direction of the vehicle interior or vice versa in the direction of the vehicle contour 17th realizable.

Furthermore, by means of the drivable sliding and swiveling device 2 to 4th a pivoting movement 16 the vehicle flap 1 around an axis 5 , e.g. the wave 9 , feasible, with the vehicle flap 1 always set back to the vehicle contour 17th can be pivoted inside the vehicle and moved back into an open position or vice versa to reach the closed position. When realizing the swivel movement 16 the retaining arms remain 3 adjacent to the respective stop 18th .

The sliding and swiveling device 2 to 4th includes at least one guide 4th and one each in the respective tour 4th recorded holding arm 3 . The respective holding arm 3 carries a rack 8th , which as part of the gear transmission 6th with the gear 7th is engaged. Each holding arm 3 (with rack 8th ) is linear in sliding movement 15th within the leadership 4th Movable back and forth. Here is the sliding movement 15th by blocking the swivel movement 16 realizable.

Any guided tour 4th with incorporated holding arm 3 (and rack 8th ) is around the axis 5 in pivoting movement 16 pivotable, the pivoting movement 16 by blocking the linear sliding movement 15th is feasible.

End to the respective holding arm 3 is at least a rear cam 13th fixed in place. The respective rear cam 13th represents a stop that the rearward pivoting movement 16 limited by blocking. Furthermore, this releases the lock 11 so that when the swivel movement is blocked 16 the sliding movement 15th is feasible.

The gear transmission 6th includes one on each shaft 9 arranged gear 7th , which with the respective rack 8th is coupled in terms of transmission technology. In the present embodiment are, for example, on the shaft 9 , two tours 4th arranged at defined intervals, each with a holding arm 3 with rack 8th and one gear each 7th are in operative connection.

The wave 9 alternatively, the transmission technology coupling is with the actuator 10 connected and the actuator 10 is preferably in an operative connection in terms of signaling and circuitry with control electronics of the vehicle. Here are the torque and speed of the actuator 10 controllable, as well as the respective position of the vehicle flap 1 can be read out as actual value.

Furthermore, by monitoring the motor current of the actuator 10 or a blocking of mechanical parts of the device can be detected by reading out the actual position. By controlling the speed of the actuator 10, the speed profile of the movement of the vehicle flap 1 to be influenced.

The actuator 10 can be reversed with regard to the direction of rotation. This can, for example, prevent the vehicle flap from being blocked 1 can be removed by icing. By means of a sensor connected to the control electronics in terms of circuit and signal technology, there is a risk of icing or an already existing icing on the vehicle flap 1 recognizable. The actuator 10 can then be reversed with regard to the direction of rotation. If necessary, the reversal can be implemented several times.
By limiting the motor current to the actuator 10 a possible risk of pinching or crushing can also be minimized or avoided.

The torque of the actuator 10 is controllable. Furthermore, the speed of the actuator is 10 controllable. The respective position of the vehicle flap 1 can be monitored.
The wave 9 or the transmission technology coupling, z. B. an intermediate gear, is with the actuator 10 connected and the actuator 10 is in signal and circuitry with a control electronics of the vehicle in operative connection.
The controllable actuator 10 can be connected to the control electronics in terms of circuitry and signaling by means of a sensor and by means of the sensor there is a risk of icing or an already existing icing on the vehicle flap 1 recognizable, whereupon the actuator 10 is reversible with regard to the direction of rotation.

The movement profile of the vehicle flap 1 is by controlling the speed of the actuator 10 changeable.

In one training, the controllable actuator 10 via an intermediate gear with the gear drive 6th be coupled. With two parallel sliding and swiveling devices 2 - 4 the synchronization can be realized by means of the intermediate gear.

In a further development, the movement of the vehicle flap 1 additionally be controllable by one or more joints and handlebars.

The mode of action is as follows and is illustrated using two holding arms as an example 3 explained.

Starting from a closed position ( 1 ) where the vehicle flap 1 aligned with the vehicle contour 17th is arranged, the actuator 10 activated manually by means of control electronics or mechanically. The drivable shaft 9 and the associated gears 7th turn in one specified first direction of rotation. Since every holding arm 3 a rack 8th is carried by the gearbox pairing of the gear 7th and rack 8th each holding arm 3 synchronously in sliding movement 15th linear in the direction of the vehicle interior, within the guide 4th , emotional.

The one on the respective holding arm 3 arranged, front cams 12th is at least in the stationary guide rail 19th linear (in sliding movement 15th ) guided. The guide rail blocks in this movement phase 19th the pivoting movement 16 . Reaches the respective rack 8th the end of the toothing of the rack 8th , limits a respective stop 18th on the respective holding arm 3 the further linear movement of the holding arm 3 with vehicle flap 1 . So that is the sliding movement 15th blocked (intermediate position, 2 ). The vehicle flap 1 is now with reference to the vehicle contour 17th set back by a defined amount, e.g. 10 mm (towards the interior of the vehicle, 2 ).

The guide rail 19th is dimensioned in its length in such a way that the cam 12th when the holding arm 3 the attack 18th has reached, is no longer performed. As a result of the actuator 10 further maintained first direction of rotation rotates the shaft 9 with holding arms 3 and vehicle flap 1 around the axis 5 steadily further and the pivoting movement 16 begins (at by stop 18th blocked sliding movement 15th ). The actuator 10 turns the shaft 9 continue in the retained first direction of rotation until the open position ( 3 ) is reached and the actuator 10 stops.

The opening position can be limited by at least one mechanical stop or an electronic limit switch. the interface 14th is now exposed for the purpose of carrying out a loading or filling process.

When the loading or filling process is finished, the actuator is 10 activated again. The actuator 10 is controlled in such a way that, for example, the shaft 9 and the associated gears 7th can be driven in the opposite, second direction of rotation. This is the pivoting movement 16 initiated in the opposite direction. The at least one lock 11 prevents undesired linear sliding movement 15th . The sliding and swiveling device 2 to 4th with vehicle flap 1 swivels around the axis 5 back up the holding arms 3 with at least one rear cam 13th are in operative connection. The respective rear cam 13th blocks further swivel movement 16 and gives the assigned lock 11 free.
As a result of the actuator that is always activated in the second direction of rotation 10 then the sliding movement begins 15th the slide - and swivel device 2 to 4th with vehicle flap 1 towards the outer vehicle contour 17th . Each holding arm 3 becomes synchronously linear in the reverse slide direction 15th within the leadership 4th , emotional. Reaches the vehicle flap 1 the vehicle contour 17th and if it rests against the existing seal, the actuator will be 10 stopped. The closed position is reached again ( 1 ).
