Description

[0028] In the following, the invention is explained in more detail with reference to the appended drawings using 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 claims, individually or in combination.

[0029] In the drawings:

[0030] FIG. 1 is a three-dimensional view of a presenting device in an initial position, i.e. a closed motor vehicle door element in the unlocked state,

[0031] FIG. 2 is a three-dimensional view of the presenting device according to FIG. 1, wherein the locking lever is shown in a locked position, and

[0032] FIG. 3 again is a three-dimensional view of the presenting device according to FIGS. 1 and 2, wherein the actuating means is shown 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.

[0033] In FIG. 1, a three-dimensional view of a presenting device 1 is reproduced. The presenting device 1 comprises an electric drive unit 2, and a gear mechanism 3 connected downstream of the electric drive unit 2, wherein the gear mechanism 3 is in engagement with a toothed rack 5 by means of a gear wheel 4. The toothed rack 5 in turn forms part of the actuating means 6 and is firmly connected to the actuating means 6. A locking lever 8 is accommodated in a pivotable manner in the interior 7 of the actuating means 6. The locking lever 8 is pivotable about an axis 9 and can be brought into form-fitting engagement with a locking contour 10. A hook-shaped end 11 engages in the locking contour 10. Of course, other forms of a form-fitting and/or force-fitting 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 and thus firmly connected as a separate component to the body of the motor vehicle. The basic structure of the electric drive unit 2 and the interaction of the electric drive unit 2 with the gear mechanism 3 and the actuating means 6 is described in the generic state of the art according to DE 10 2018 132 665.3, this part of the description of the state of the art is explained in full in relation to the content of the disclosure of the application.

[0034] The actuating means 6 is shown in an initial position, wherein the actuating means is shown in the position where it is completely retracted into the motor vehicle door element 13. The motor vehicle door element 13 is consequently closed and the presenting device is out of operation.

[0035] If an operator of the motor vehicle transmits a signal to the presenting device 1 that the door is to be presented, a gear mechanism 15 is activated by means of a locking drive 14, whereby an operating lever 16 is moved. The operating lever 16 pivots an actuating shaft 17, wherein the actuating shaft 17 moves a sliding element 18 in the interior 7 of the actuating means 6, whereby the locking lever 8 is pivoted 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 the motor vehicle door element 13 can be safely guided and presented.

[0036] The presentation of the motor vehicle door element 13 is thus also safely possible when, for example, external influences act on the motor vehicle door element. If the motor vehicle is, for example, on a sloping road and/or stormy wind movements also act on the motor vehicle door element, the presenting device can be used to ensure that the motor vehicle door element 13 is guided safely at all times. The motor vehicle receives a control signal from the operator that the motor vehicle door element 13 is to be opened. The control signal causes, on the one hand, an electrical unlocking of a motor vehicle latch, the presenting device 1 preferably interacting with an electrically unlockable motor vehicle lock, so-called electric locks. The unlocked latch releases a locking mechanism so that the locked actuating means can open the door 13. During the presentation, the actuating means is guided between the gear wheel and a guide means 19.

[0037] The locked state of the presenting device 1 is shown in FIG. 2.

[0038] 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 unit 2, wherein an actuating path S is shown 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 securely held 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 gear mechanism carrier 21 pivots in the direction of the arrow P2 in FIG. 2. The movement of the extension 20 of the gear mechanism 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 controller.

[0039] A control signal for the locking drive 14 causes the locking drive 14 to pivot the operating lever 16 via the gear mechanism 15. In this exemplary embodiment, the operating lever 16 and the gear mechanism 15 are in operative connection by means of a recess 23 and a cylindrical pin 24 arranged on a gear wheel of the gear mechanism 15. The pivoting of the operating lever 16 causes the actuating shaft 17 to be rotated in the direction of the arrow P3, as a result of which the sliding element 18 pivots the locking lever 8 about the axis 9 and thus disengages 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 to the motor vehicle door element 13.

[0040] If, for example, in the position of the motor vehicle door element 13, as shown in FIG. 3, there is no adequate power supply available for the locking drive 14, the operating lever 16 can be grasped, for example through an opening in a door panel, and can release the locking lever 6 from the engagement with the locking contour 10. It is of course also conceivable that the operating lever 16 is connected to a Bowden cable, for example, so that the operating lever 16 can be operated remotely.

[0041] A control unit 25 which can also be seen in FIG. 3 is electrically connected, on the one hand, to the presenting device 1 and, on the other hand, to a further sensor 26. The control 25 is connected by means of a connecting line 27 to the electric drive units 2, 14 of the presenting device 1 and also, for example, to an inside door handle 28. The control 25 can be a control 25 of the motor vehicle or else a control 25 inside the door, which is assigned, for example, to the presenting device 1 and/or a latch or is part of the presenting device 1 itself. By means of the control unit 25, it is possible to connect the functions of the further sensors 26 and the inside door handle 28, but also to connect them to a control signal from an operator of the motor vehicle. In this combination, it is thus possible, on the one hand, to initiate a normal presentation or, on the other hand, to display further functions by means of the further sensors.

[0042] If, for example, the inside door handle 28 is now operated, wherein a child safety device is switched on at the same time by the operator of the motor vehicle in relation to the inside door handle 28, the presenting device 1 can prevent the opening process. To prevent the opening, the locking lever 8 can be brought into engagement with the contour 10, wherein a braking effect can be introduced into the door element 13 by means of the electric drive unit 2. In this case, the presenting device 1 serves as a child safety device.

[0043] Even in the case of manual opening, movement of the door element 13 can be prevented by means of the presenting device 1 in order, for example, to provide an anti-theft device. In the representation of these extended functions of the presenting device 1, it is advantageous that no additional components are required in the door element and/or in the latch.
