Description

BRIEF DESCRIPTION OF DRAWINGS

(1) In the following, the invention is explained in more detail with reference to the accompanying drawings by means of an exemplary embodiment. However, the principle applies that the exemplary embodiment does not limit the invention, but merely represents an embodiment. The features shown can be implemented individually or in combination with further features of the description as well as the patent claims.

(2) The figures show:

(3) FIG. 1 shows a three-dimensional view of a presenting device in an initial position, that is, of a closed motor vehicle door element and in the unlocked state,

(4) FIG. 2 shows a three-dimensional view of the presenting device according to FIG. 1, with the locking lever reproduced in a locked position, and

(5) FIG. 3 in turn shows a three-dimensional view of the presenting device according to FIGS. 1 and 2, wherein the actuating means is reproduced extended, i.e. FIG. 3 shows the position of the actuating means in a presenting position of the motor vehicle door element, wherein the motor vehicle door element is held in the presenting position by means of the locking means.

DETAILED DESCRIPTION

(6) FIG. 1 shows a three-dimensional view of a presenting device 1. The presenting device 1 comprises an electric drive 2, a gear 3 connected downstream of the electric drive 2, the gear 3 being in engagement with a rack 5 by means of a gear wheel 4. The rack 5 in turn forms part of the actuating means 6 and is fixedly connected to the actuating means 6. A locking lever 8 is accommodated in the interior 7 of the actuating means 6 so that it can pivot. The locking lever 8 can be pivoted about an axis 9 and can be brought into positive engagement with a locking contour 10. In doing so, a hook-shaped end 11 engages the locking contour 10. Of course, other forms of a positive and/or non-positive connection between the locking lever 8 and the locking contour 10 are also conceivable according to the invention. In this embodiment, the locking contour 11 is screwed to the body of the motor vehicle as a separate component and is thus firmly connected. The basic structure of the electric drive 2 and the interaction of the electric drive 2 with the transmission 3 and the actuating means 6 are described in the generic prior art according to (DE 10 2018 132 665.3), this part of the description of the prior art being fully declared to be part of the disclosure content of the application.

(7) The actuating means 6 is reproduced in an initial position, wherein the actuating means is reproduced fully retracted into the motor vehicle door element 13. Consequently, the motor vehicle door element 13 is closed and the presenting device is out of operation.

(8) If a signal is now transmitted to the presenting device 1 by an operator of the motor vehicle that the door is to be presented, a gear 15 is actuated by means of a locking drive 14, whereby an operating lever 16 is moved. The operating lever 16 pivots an actuating shaft 17, the actuating shaft 17 moving a sliding element 18 inside 7 of the actuating means 6, causing the locking lever 8 to pivot about the axis 9 in the direction of the arrow P1. The locking lever 8 comes into engagement with the locking contour 10, so that safe guiding and presenting of the motor vehicle door element 13 is possible.

(9) The presenting of the motor vehicle door element 13 is thus also possible in a safe manner if, for example, external influences act on the motor vehicle door element. If, for example, the motor vehicle is on a sloping road and/or stormy wind movements additionally act on the motor vehicle door element, safe guiding of the motor vehicle door element 13 can be ensured at any time by means of the presenting device. The motor vehicle receives a control signal through the operator that the motor vehicle door element 13 is to be opened. On the one hand, the control signal causes an electrical unlocking of a motor vehicle lock, wherein the presenting device 1 preferably cooperates with an electrically unlockable motor vehicle lock, so-called B-locks. The unlocked lock releases a latch so that the locked actuating means can present the door 13. During the presenting process, the actuating means is guided between the gear wheel and a guide means 19.

(10) The locked state of the presenting device 1 is shown in FIG. 2.

(11) FIG. 3 shows the presenting device 1 in a presenting position of the motor vehicle door element 13. The actuating means 6 has been moved completely out of the motor vehicle door element 13 by means of the drive 2, a displacement S being drawn in FIG. 3. The locking lever 8 is still in engagement with the locking contour 10, so that the motor vehicle door element 13 is held securely in the presenting position. If the motor vehicle door element 13 is now gripped, for example by the operator of the motor vehicle, an extension 20 of the transmission carrier 21 pivots in the direction of the arrow P2 in FIG. 2. The movement of the extension 20 of the transmission carrier 21 can be detected by means of the sensor 22, whereby a control signal can be transmitted to the locking drive 14 by means of the control system.

(12) A control signal for the locking drive 14 causes the locking drive 14 to pivot the operating lever 16 via the gear 15. In this embodiment, the operating lever 16 and the gear unit 15 are operatively connected by means of a recess 23 and a cylindrical pin 24 arranged on a gearwheel of the gear unit 15. Pivoting the operating lever 16 causes the actuating shaft 17 to be rotated in the direction of the arrow P3, causing the sliding element 18 to pivot the locking lever 8 about the axis 9, thereby disengaging the locking lever 8 from the locking contour 10. The motor vehicle door element 13 can be opened manually and the actuating means 6 is returned into the motor vehicle door element 13.

(13) If it now happens, for example, in the position of the motor vehicle door element 13 as reproduced in FIG. 3, that no sufficient power supply is available for the locking drive 14, the operating lever 16 can be gripped, for example through an opening in a door panel, and the locking lever 6 is released from engagement with the locking contour 10. It is of course also conceivable that the operating lever 16 is connected to, for example, a Bowden cable, so that the operating lever 16 can be operated remotely.

(14) FIG. 3 further shows a control unit 25 which, on the one hand, is electrically connected to the presenting device 1 and, on the other hand, to a further sensor 26. The control unit 25 is connected by means of a connecting line 27 to the electric drives 2, 14 of the presenting device 1 and further, by way of example, to an interior door handle 28. In this context, the control unit 25 may be a control unit 25 of the motor vehicle or may also be a door-internal control unit 25 which, for example, is associated with the presenting device 1 and/or a lock or represents a part of the presenting device 1 itself. By means of the control unit 25, it is possible to combine the functions of the further sensors 26 and the interior door handle 28, but also a control signal from an operator of the motor vehicle. In this combination it is thus possible, on the one hand, to initiate a usual presenting or, on the other hand, to represent further functions by means of the further sensors.

(15) If, for example, the inner door handle 28 is now actuated, while at the same time a child safety lock has been switched on by the operator of the motor vehicle with respect to the inner door handle 28, the presenting device 1 can prevent the opening process. To stop the opening, the locking lever 8 can be engaged with the contour 10, whereby a braking effect can be introduced into the door element 13 by means of the electric drive 2. In this case, the presenting device 1 serves as a child safety device.

(16) Even in the case of manual opening, movement of the door element 13 can be prevented by means of the presenting device 1, for example in order to represent an anti-theft device. It is advantageous in the representation of these extended functions of the presenting device 1 that no additional components are required in the door element and/or in the lock.
