  • the door can be pivoted relative to the housing and thus moved between the closed position and the open position, in particular when the device is fully manufactured.
  • the translational movement of the threaded nut relative to the threaded spindle allows the hinge parts, in particular the aforementioned pivot axis, to be pivoted relative to one another, whereby the door can be pivoted relative to the housing.

  • the feature that the torque that can be transmitted between the drive motor and the threaded spindle is automatically limited to the maximum value by means of the slipping clutch is to be understood in particular as meaning that an external control, that is to say a control from outside, that is to say from a component external to the slipping clutch, is not necessary to limit the torque to the maximum value by means of the slipping clutch, but rather the slipping clutch itself or independently and therefore automatically prevents the torque from exceeding the maximum value.
  • the slip clutch comprises, for example, a first coupling part rotatable about the axis of rotation and a second clutch part rotatable about the axis of rotation, which, for example, is at least partially, in particular at least predominantly or completely, in the axial direction of the slip clutch and thus along the axis of rotation.

  • a transmission of an excessively large torque from the threaded spindle to the drive motor and vice versa can be avoided, so that damage to the drive device can be avoided in a particularly simple, space-saving, weight-saving and cost-effective manner.
  • the slip clutch which is also referred to as a torque limiter, is preferably a, in particular purely, mechanical clutch, by means of which the maximum torque that can be transmitted from the threaded spindle to the drive motor or vice versa or the maximum force that can be transmitted is limited.
  • the stated maximum value is a threshold value. If the torque acting on the slipping clutch by the threaded spindle or the drive motor exceeds the threshold value, the slipping clutch or the clutch parts slip, which limits the maximum transferable torque.
  • the threshold value can be specified and thus defined in particular by appropriate design of the slip clutch, in particular the clutch parts.
  • the invention is based in particular on the following findings:
  • the drive motor can be assigned to an electronic computing device, which can, for example, be part of the drive device.
  • control is designed to control the drive motor, in particular electrically or electronically, and thereby in particular to control or regulate it.
  • a force or a torque which the drive motor provides in particular via its rotor and is provided, for example, for driving the threaded spindle, can be set or controlled or regulated.
  • this setting, i.e. controlling or regulating, the torque by means of the electronic computing unit could not work, i.e.
  • the slip clutch is a countermeasure to prevent excessive torque provided by the drive motor from being transmitted to the threaded spindle, for example in the event of a fault.
  • slipping occurs in particular when the drive motor provides a torque whose value is greater than the maximum value, so that this torque, whose value is greater than the maximum value, is not completely transmitted to the threaded spindle via the slip clutch.
  • the drive device In principle, it would be conceivable for the drive device to allow the door to be pivoted manually relative to the housing. If a person manually pivots the door relative to the housing, the threaded nut drives the threaded spindle so that the threaded spindle is rotated about the axis of rotation. As a result, the threaded spindle, in particular via the slip clutch, drives the drive motor, in particular its rotor. If the door were to be pivoted manually excessively quickly and/or forcefully, a torque could act on the threaded spindle or the threaded spindle could provide a torque whose value is greater than the maximum value.
  • the slip clutch prevents a torque provided by the threaded spindle, the value of which is higher than the maximum value, from being transmitted via the slip clutch to the drive motor, since in this case the slip clutch slips. This means that, for example, with intentional Misuse or vandalism as well as damage caused by unintentional, excessively fast movement of the door can be avoided.
  • the torque that can be transmitted between the drive motor and the threaded spindle is limited to at least one maximum value in a first direction of rotation running around the axis of rotation, with the slipping clutch between the drive motor and the torque that can be transmitted to the threaded spindle in a second direction of rotation that extends around the axis of rotation and is opposite to the first direction of rotation is limited to a second maximum value that is different from the at least one maximum value.
  • a first torque can be transmitted from the drive motor, in particular from the rotor, to the threaded spindle via the slip clutch and, conversely, from the threaded spindle via the slip clutch to the drive motor or the rotor, a maximum second torque can be transmitted, the second torque being greater or smaller than is the first torque.
  • slip clutch has the previously described clutch parts.
  • the first coupling part has a first toothing on its first end face facing the coupling parts in the axial direction of the second coupling part.
  • the second coupling part has a second toothing on its second end face facing the first coupling part in the axial direction of the coupling parts.
  • the axial direction of the respective coupling part coincides with the axial direction of the slip clutch and thereby with the axis of rotation, with the axial directions of the coupling parts coinciding.
  • the first toothing has successive first teeth in the circumferential direction of the coupling parts extending around the axial directions of the coupling parts, which are preferably spaced apart from one another, so that respective first tooth gaps of the first are between the first teeth Gearing are arranged.
  • the second toothing has second teeth in succession in the circumferential direction of the coupling parts extending around the axial directions of the coupling parts, which are preferably spaced apart from one another, so that respective second tooth gaps of the second toothing are preferably arranged between the second teeth in the circumferential direction of the coupling parts.
  • the respective first tooth also has first tooth flanks with different pitches arranged in the circumferential direction of the coupling parts on opposite sides, the respective second tooth having tooth flanks with different pitches arranged on opposite sides in the circumferential direction of the coupling parts.
  • the respective maximum value can be set using the tooth flanks, especially their pitches.
  • the tooth flanks in particular their gradients, can be used to set how large the highest torque that can be transmitted between the coupling parts is or from what amount of torque the slip clutch slips. Due to the different pitches of the tooth flanks of the respective tooth, it can be realized in a cost-, space- and weight-efficient manner that, for example, from the drive motor to the threaded spindle via the slip clutch at most the first torque and from the threaded spindle to the drive motor via the slip clutch at most the second Torque can be transmitted, the second torque being greater or smaller than the first torque.

  • the slip clutch has a spring device which provides a spring force acting in the axial direction of the slip clutch, by means of which the coupling parts are held in mutual support in the axial direction of the coupling parts, in particular in such a way that the teeth engage with one another.
  • the spring device comprises at least one disc spring or a plurality of disc springs, which can be designed separately from one another and/or can be arranged one after the other in the axial direction of the coupling parts.
