Abstract

The invention relates to a drive arrangement for the motorized adjustment of a closure element of a motor vehicle, wherein the drive arrangement, in the installed state, is coupled in drive terms to the closure element. It is proposed for the drive arrangement to have at least one drive, which is intended for generating drive movements and in or on which is arranged an acoustic indicator for supplying acoustic feedback to the user.

Claims

1. A drive arrangement for the motorized adjustment of a closure element of a motor vehicle, wherein the drive arrangement, in the installed state, is coupled in drive terms to the closure element, wherein the drive arrangement has at least one drive, which is intended for generating drive movements and in or on which is arranged an acoustic indicator for supplying acoustic feedback to the user.

2. The drive arrangement according to claim 1, wherein the acoustic feedback covers the running of the motorized adjustment of the closure element, a situation where something gets caught, a situation where the closure element reaches a predetermined position, the occurrence of a predetermined fault situation.

3. The drive arrangement according to claim 1, wherein the drive is configured as an elongate linear drive which, at each end, has a mechanical connection for delivering the drive moments, which is configured in particular as part of a ball-and-socket joint.

4. The drive arrangement according to claim 1, wherein the drive has a drive housing, and in that the acoustic indicator is arranged in or on the drive housing.

5. The drive arrangement according to claim 1, wherein the drive is configured as a spindle drive and has a drive motor and a spindle/spindle-nut gear mechanism, which is arranged downstream of the drive motor.

6. The drive arrangement according to claim 1, wherein the drive housing has a bush-like termination piece at least at one end, and in that the acoustic indicator is arranged, at least in part, within the bush-like termination piece.

7. The drive arrangement according to claim 1, wherein the acoustic indicator has a dedicated housing, and in that the housing of the acoustic indicator is positioned on the drive.

8. The drive arrangement according to claim 1, wherein the drive housing or the drive-module housing is configured, and the acoustic indicator is arranged, such that the drive housing or the drive-module housing serves as a resonating body for the acoustic indicator.

9. The drive arrangement according to claim 1, wherein the drive has an electrical connection arrangement, and in that the acoustic indicator is arranged within the electrical connection arrangement.

10. The drive arrangement according to claim 9, wherein the electrical connection arrangement comprises a plug arrangement and the acoustic indicator is arranged in or on the plug arrangement.

11. The drive arrangement according to claim 1, wherein the acoustic signals of the acoustic indicator are generated by an electric acoustic generator.

12. The drive arrangement according to claim 1, wherein the acoustic signals of the acoustic indicator are generated by a relative movement of components of the drive during the motorized adjustment of the drive.

13. A closure-element arrangement of a motor vehicle, having a closure element and a drive arrangement according to claim 1 for the motorized adjustment of the closure element, wherein, in the installed state, the drive arrangement, in particular the acoustic indicator, is exposed at least in part in relation to the motor-vehicle environment at least over an adjusting region of the closure element.

14. The closure-element arrangement according to claim 13, wherein, with the closure element closed, the drive arrangement is covered by the closure element.

15. The closure-element arrangement according to claim 13, wherein the closure element is a tailgate, a boot lid, a bonnet, a side door, a cargo-space hatch closure, a window, a pop top or the like of a motor vehicle.

16. The drive arrangement according to claim 3, wherein the acoustic indicator is arranged in the region of at least one of the mechanical connections.

17. The drive arrangement according to claim 4, wherein drive housing comprises two sub-housings which run telescopically one inside the other during the motorized adjustment.

18. The drive arrangement according to claim 9, wherein the electrical connection arrangement has a cable-like supply line, and in that the acoustic indicator is arranged in or on the cable-like supply line.

19. The drive arrangement according to claim 10, wherein the plug arrangement comprises an intermediate plug, in or on which the acoustic indicator is arranged.

20. The drive arrangement according to claim 11, wherein the acoustic indicator comprises an electric loudspeaker, an electric buzzer or the like.
