Embodiment Construction

[0029] figure 1 A drive mechanism 10 is shown, which is suitable, for example, for locking and unlocking an electric vehicle lock.

[0030] The drive mechanism 10 includes a drive element 12 configured as a spindle 12a and a drive motor 14 configured as an electric motor. The first worm gear 16 and the second worm gear 18 are connected between the drive motor 14 and the drive element 12 to increase or decrease the rotational drive speed and drive torque of the drive motor 14 .

[0031] The first worm gear 16 includes a first worm gear shaft 20 rotationally fixedly coupled to a drive shaft 22 of the drive motor 14 and a first gear 24 in meshing engagement with the first worm gear shaft 20 . The first worm gear 24 is rotationally fixedly coupled to and arranged coaxially with the second worm gear shaft 26 . The second worm gear shaft 26 is in meshing engagement with a second worm gear 28 . The second worm gear shaft 26 and the second worm gear 28 together form the second worm...

Abstract

The invention relates to a drive mechanism having a double worm gear and a related apparatus including the drive mechanism. The drive mechanism has a drive motor and a drive element drivable by the drive motor. A first worm gear, which has a first worm gear shaft and a first worm wheel, and a second worm gear, which has a second worm gear shaft and a second worm wheel, are connected between the drive motor and the drive element.

Description

technical field [0001] The invention relates to a drive mechanism with a double worm gear having a drive motor and a drive element drivable by the drive motor. The invention further relates to a device for opening or closing a door or cover, a device for actuating a lock of a motor vehicle, a camera device and a seat adjustment device. Background technique [0002] For example, drive mechanisms of the type originally named are used in vehicles to actuate various devices to increase the comfort of the vehicle operator, such as locking mechanisms for doors or lids, extension mechanisms for rear view cameras, or seat adjustment devices. [0003] As the number of such devices in a vehicle increases, it becomes increasingly difficult to accommodate the associated drive mechanism in the existing build space of the vehicle. Contents of the invention [0004] The underlying object of the present invention is to provide a drive mechanism which requires less construction space and ...
