Description

The present invention relates to a flap assembly, in particular a tank flap assembly, for a motor vehicle, in particular a passenger car and a motor vehicle with such a flap arrangement.

From the EP 1 527 930 A2 a device for locking and unlocking a tank flap of a motor vehicle with a locking member is known, which is positively engageable with a receiving element in engagement. A switching element activates an actuator when pressure on the fuel filler flap, which disengages the receiving element.

An object of an embodiment of the present invention is to provide a motor vehicle with an improved door assembly.

This object is achieved by a flap arrangement with the features of claim 1. Claim 10 provide a corresponding motor vehicle under protection. Advantageous embodiments of the invention are the subject of the dependent claims.

According to one aspect of the present invention, a motor vehicle flap arrangement, in particular a passenger car flap arrangement, an openable flap, in particular a fuel filler flap for covering a tank recess of a body of the motor vehicle. In one embodiment, a filler neck for fuel and / or an electrical plug for charging an energy store of the motor vehicle, which is covered by the flap in a closed position, at least substantially, is disposed in the tank well.

In one embodiment, the flap is movable, in particular rotatable and / or -schiebbar mounted on a body of the motor vehicle. In one embodiment, the flap of the closed position in which it covers the tank well, at least substantially, and / or aligned with an outside of the body, at least substantially, movable in an opening direction into an open position in which they the tank well at least essentially releases and / or protrudes from the outside of the body, in particular at an angle of at least 45 °, in particular at least 60 °. In a further development, the flap of the closed position in the opening direction in an open position upstream actuating position is movable, in which it protrudes from the body, in particular at an angle of at most 40 °, in particular at most 30 °, and engageable by at least one finger for further opening behind is and / or, at least substantially, still no access to the tank well allowed. Additionally or alternatively, the flap may be movable from the closed position against the opening direction into an activating position in which it is engaged in the outside of the body, in particular to effect opening of the flap. The flap can be fixable in one or more of these positions, in particular frictionally or positively, in particular by a corresponding stop.

In one aspect of the present invention, the flap assembly includes a magnet assembly having one or more magnetic members for magnetically biasing the flap in the opening direction. As a result, in one embodiment, the flap can be moved magnetically in an advantageous manner from the closed position in the opening direction into the actuating or open position.

One or more magnetic elements of the magnet arrangement can be permanently magnetic or permanent magnets. As a result, in one embodiment, a cost-effective and / or robust magnet arrangement can be made available. Additionally or alternatively, one or more magnetic elements of the magnet assembly may be electromagnetically or electromagnets. As a result, in one embodiment, the magnetic bias can be advantageously set electrically, in particular (de) activated.

One or more permanent or electromagnetic magnetic elements of the magnet arrangement can be arranged body-side in one embodiment, in particular fixed, in particular rigid, be connected to the body. Additionally or alternatively, one or more permanent or electromagnetic magnetic elements of the magnet arrangement can be arranged on the flap side, in particular fixedly, in particular rigidly, connected to the flap. In particular, a core and / or a coil of an electromagnet of the magnet arrangement can be rigidly connected to the body or flap.

In particular, when the magnet assembly at least one permanent magnet element pair with a flap-side and a body-side permanent magnet element opposite polarity or Having orientation that face each other in one embodiment in the closed position and repel each other to bias the flap magnetically in the opening direction may be provided in one embodiment, an openable latch for, in particular positive locking the flap against movement of the flap in the opening direction. However, such a bolt may also be provided in an electromagnetic magnet arrangement.

If the latch is opened, the magnet arrangement moves the flap in the opening direction, in particular in its actuating position, in one embodiment.

The bolt is rotatable in one embodiment and / or -schiebbar mounted on the body or flap. In one embodiment, the latch can be opened by engaging the flap against the opening direction from the closed position to the activation position of the flap. In a further development of the latch by such engagement of the flap mechanically, in particular by a slotted guide, a run-on slope or the like, can be opened. In another embodiment of the bolt is openable by such engagement of the flap by electric motor. In particular, a detection means for detecting the activation position of the flap may be provided which actuates an electric motor based on detecting the activation position of the flap to open the bolt by an electric motor.

In one embodiment, the electric motor returns the latch after a predetermined period of time back into a locking position. In particular, the electric motor can be coupled by a gear with the bolt, which is infinitely rotatable and, in particular in a complete revolution, again reaches a starting position. In this way, the electric motor can be activated by the detection means to perform a complete revolution, by which he first opens the latch and then returned to a locking position. Similarly, the electric motor can reset the latch on reaching a predetermined position of the flap, in particular the actuation or open position again in a locking position.

In particular, when the electric motor resets the bolt back into a locking position, it may be appropriate that the flap is locked by moving against the opening direction, in particular in the closed position, again, without the bolt is adjusted for this purpose. Therefore, in one embodiment, the bolt in a locking position against the opening direction is mechanically overflowable. For this purpose, the bolt, in particular elastic, biased into the locking position and be displaced by the closing of the flap from this, so that it returns to an overflow back into the locking position and then engages behind an undercut to lock the flap. Similarly, an undercut which is slotted in particular can be elastically deformed and thus opened when the locking bar overflows in the locking position, which snaps back after overflowing and thus engages behind the bolt in order to lock the flap.

According to one aspect of the present invention, the magnet assembly is switchable between an active state in which it magnetically biases the flap in the opening direction and a passive state in which it magnetically biases the flap in the opening direction, at least substantially, not or at least weaker than in the active state , in particular with at most half the opening force compared to the active state.

As a result, in one embodiment, the magnet arrangement can be advantageously (de) activated selectively, in particular by engagement of the flap against the opening direction from the closing position to the activation position of the flap.

In one embodiment, the magnet arrangement is mechanically switchable between the active state and the passive state, in particular between an active position and a passive position movable. In particular, a flap-side and / or a body-side permanent magnet element of a permanent magnet element pair opposite polarity or orientation in an embodiment between an active position in which they face each other and so magnetically bias the flap in the opening direction, and a passive position in which they do not face each other or at least cover less and / or are more widely spaced and so bias the flap in the opening direction not or weaker magnetic. In one embodiment, the magnet assembly biases the flap even in the passive position in the opening direction, in particular at least 5 N, preferably at least 15 N. In particular, a flap-side and a body-side permanent magnet element of a permanent magnet element pair opposite polarity can still face each other even in the passive position or each other , at least partially, thereby cover in one embodiment in the passive position, a resistance against an unwanted engagement of the flap, for example, by brushing a car wash or the like, counteracted. Preferably, the magnet arrangement then biases the flap more magnetically in the open position in the active position, in particular by at least 5 N, preferably at least 15 N stronger.

This can in particular be combined with the above-explained latch, in particular by arranging in one embodiment at least one magnetic element of the magnet arrangement on the latch. If this is moved out of or into the locking position, a pair of permanent magnet elements can thereby be mechanically adjusted.

In one embodiment, the magnet assembly is electrically switchable between the active state and the passive state. In particular, the flap arrangement for this purpose may comprise a power supply means for energizing one or more electromagnetic magnetic elements of the magnet arrangement. In a further development, the magnet arrangement can be energized by engagement of the flap against the opening direction from the closed position to the activated position. In particular, a detection means may be provided for detecting the activation position of the flap, which energizes the magnet arrangement on the basis of detecting the activation position of the flap in order to magnetically bias the flap in the opening direction.

In one embodiment, the flap assembly has a spring means for mechanically biasing the flap against the opening direction. This spring means may comprise one or more rotary, tension, pressure, plate and / or form springs. In one embodiment, a biasing force of the spring means against the opening direction, in particular at least in the closed position of the flap, smaller than a biasing force of the, in particular in the active state connected, magnet arrangement in the opening direction, so that, in particular switched to the active state, the magnetic arrangement, the spring means overcome and the flap can move in the opening direction.

In particular, in order to prevent unwanted fixing during the magnetic opening of the flap or overcome, in particular by a spring means described above, the Bestromungsmittel can energize the magnet assembly for a predetermined time. In one embodiment, the spring means pulls the power back to the flap again in the closed position and fixes them there force fit.

The above-described detection means for detecting an opposite to the opening direction against a closed position recessed activation position of the flap may in particular one, in particular optical, magnetic or electrical, distance sensor, a Hall sensor and / or a pressure switch. In one embodiment, the Hall sensor detects a flap-side permanent magnet element of the magnet assembly, in particular its position or distance, or is configured for this purpose and arranged accordingly. In this way, in one embodiment, the permanent magnet element of the magnet arrangement at the same time for Hall sensor-based detection of the activation position of the flap 1 be used or be.

A means in the sense of the present invention may be designed in terms of hardware and / or software, in particular a data or signal-connected, preferably digital, processing, in particular microprocessor unit (CPU) and / or a memory and / or bus system or multiple programs or program modules. The CPU may be configured to execute instructions implemented as a program stored in a memory system, to capture input signals from a data bus, and / or to output output signals to a data bus. A storage system may comprise one or more, in particular different, storage media, in particular optical, magnetic, solid state and / or other non-volatile media.

Further advantageous developments of the present invention will become apparent from the dependent claims and the following description of preferred embodiments. This shows, partially schematized:

1 a fuel filler flap assembly of a motor vehicle according to an embodiment of the present invention in a section along the line II in 2 in a closed position;

2 the tank flap assembly of 1 in a section along the line II-II in 1 ;

3 the tank flap assembly of 1 in an activation position;

4 the tank flap assembly of 1 in an operating position;

5 a tank flap assembly of a motor vehicle according to a further embodiment of the present invention in a closed position in 1 corresponding representation;

6 the tank flap assembly of 5 in an activation position; and

7 the tank flap assembly of 5 in an operating position.

1 shows a fuel filler flap assembly of a motor vehicle according to an embodiment of the present invention in a section along the line II in FIG 2 in a closed position, 2 this tank flap assembly in a section along the line II-II in 1 ,

The tank flap assembly has an openable fuel filler flap 1 for covering a tank pit 2 a body 3 of the motor vehicle, which is rotatably mounted on the body 3 of the motor vehicle.

The flap 1 is from one in 1 shown closed position in which they the tank well 3 covering and with an outside of the bodywork 3 is aligned, in an opening direction (clockwise rotation in 1 ) into an in 4 shown actuating position movable in which it protrudes from the body, is engaged behind by a finger for further opening and still does not allow access to the tank trough. From this operating position, it is manually movable further in the opening direction into an open position in which it releases the tank recess and protrudes from the outside of the body at an angle of approximately 90 ° (not shown).

Contrary to the opening direction or mathematically positive in 1 Can the flap 1 from the closed position ( 1 ) manually in a 3 shown activation position to open the flap 1 to effect, as described below.

The flap arrangement has a magnet arrangement in the form of a pair of permanent magnet elements with a flap-side permanent magnet element 4A , rigid with the flap 1 is connected, and a body-side permanent magnet element 4B opposite polarity or orientation, the rigid with a bolt 5 is connected.

The bolt 5 is movable (horizontally in 1 ) on the body 3 stored.

To open the flap 1 the user presses them from the closed position into the activation position ( 1 → 3 ). A detection means in the form of a Hall sensor or pressure switch 6 detects the activation position of the flap and then actuates an electric motor 7 to the bolt 5 electromotive from its locking position (see. 1 ) and thereby open. In this case, the permanent magnet element 4A at the same time for Hall sensor-based detection of the activation position of the flap 1 used.

The electric motor 7 is through a gear with the bolt 5 coupled, which is infinitely rotatable and reaches a starting position by a complete rotation of 360 ° again. Will the electric motor 7 through the detection means 6 activated, he completes a complete turn, through which he locks the bar 5 first opens and then returns to the locking position ( 3 → 4 ).

Will the bar 5 open, so by the Mitbewegung of the bar 5 arranged permanent magnet element 4B the magnet assembly mechanically from a passive state or a passive position, in which the permanent magnet elements 4A . 4B not directly opposite each other or each other in the direction of the bolt 5 are spaced so that they do not cover each other or at least less (cf. 1 ), switched to an active state or an active position or moved (see. 3 ), in which they face each other or cover more. In a modification, not shown, the permanent magnet elements 4A . 4B each other also in the passive state or the passive position opposite or each other, at least partially, cover, in particular, to an unwanted engagement of the flap 1 To counteract, for example, by a brush a car wash.

In this active position spans the magnet assembly 4A . 4B the flap 1 magnetically in the opening direction, thereby moving them due to the opened latch 5 in their operating position (cf. 4 ) when the user the flap 1 releases.

The electric motor 7 puts the bar 5 then by turning back into the locking position back.

To the flap 1 to lock again after use in the closed position by moving against the opening direction ( 4 → 1 ), without the bolt 5 must be adjusted for this purpose, this bar in the locking position against the opening direction is mechanically overflowable. The flap points to this 1 a slotted undercut 8th on (cf. 2 ) when overflowing the bolt 5 is elastically deformed in the locking position and thus opened. After overrunning, the undercut snaps 8th back and thus grasps behind the bolt 5 to the flap 1 to lock positively.

5 - 7 show a fuel filler flap assembly of a motor vehicle according to a further embodiment of the present invention in a closed position in 1 . 3 . 4 corresponding representation. Corresponding elements are designated by identical reference numerals, so that reference is made to the above description and will be discussed below only differences.

In the execution of 5 the magnet arrangement has a flap-side permanent magnet element 4A , rigid with the flap 1 is connected, and a body side solenoid member 4C opposite polarity or orientation, the core and coil rigid with the body 3 are connected.

This magnet arrangement 4A . 4C is electrically between an active state in which a Bestromungsmittel 10 the solenoid element 4C energized such that it is the permanent magnet element 4A repels and thereby the flap 1 biased in the opening direction, and a passive state switchable, in which the Bestromungsmittel 10 the solenoid element 4C not energized.

Captures the detection means in the form of a pressure switch 6 ' the activation position of the flap 1 (see. 6 ), the energizing agent is energized 10 the solenoid element 4C as explained above. Thus, the magnet arrangement 4A . 4C by an engagement of the flap 1 can be energized against the opening direction from the closed position to the activation position.

The flap assembly of the embodiment of 5 has a spring means 9 for mechanical pretensioning of the flap 1 opposite to the opening direction, the in 5 is exemplified as a torsion spring.

The spring means 9 Shut up 1 closed in passive state. Its biasing force against the opening direction is in the closed position of the flap 1 but smaller than a biasing force of the switched into the active state magnet assembly 4A . 4C in the opening direction, so that the switched into the active state magnet assembly, the spring means 9 overcome and shut up 1 can move in the opening direction.

To open the flap 1 the user presses them from the closed position into the activation position ( 5 → 6 ). The detection means 6 ' detects the activation position of the flap. The energizing agent is then energized 10 the solenoid element 4C , This opens the door 1 magnetically in the opening direction, overcomes due to the larger magnetic biasing force, the oppositely acting biasing force of the spring means 9 and so he moves the flap 1 in the operating position (see. 7 ) when the user the flap 1 releases.

The energizer 10 energizes the magnet arrangement 4A . 4C for a given time. Then it switches the magnet arrangement 4A . 4C by interrupting the energizing again in the passive state. In this tension the spring means 9 the flap 1 again against the opening direction and fixes this non-positively in the closed position. The spring means 9 may have a transition point between the actuating and open positions, so that it biases the flap in the operating position in the closed position, in the open position, however, not.

Likewise, the flap 1 in the open position, for example by a toggle kinematics, be fixed (not shown).
