Embodiment Construction

[0018] figure 1 and 2 The schematic structure of the rotary adjuster according to the invention is shown in each case in section. The rotary adjuster consists of a statically arranged, stamp-shaped stator 3 , around which a rotor 4 is arranged. The rotor 4 is designed as a hollow-cylindrical rotor which is rotatably mounted on a stationary housing part 8 of the rotary actuator.

[0019] The support plate 6 carrying the sensor surface 2 is connected to the stator 3 via spring elements 7 . The sensor area 2 , shown only schematically here, is preferably formed by a conductor structure extending over a plane, which is electrically connected to an electronic processing unit, not shown. The conductor structure forms a capacitor system, which can evaluate the approach of an object on the operating surface 1 formed by the surface of the rotor 4 in a position-resolved manner by means of the change in capacitance.

[0020] In order to achieve that the rotor 4 can rotate relative to...

Abstract

A rotary actuator includes a stator on which a sensor surface is arranged and a rotor configured to rotate about the stator. The rotor forms an actuating surface for the sensor surface. An interval fixing device such as a rotationally fixed sliding disk is arranged between the actuating surface and the sensor surface. A spring is configured to press the sensor surface towards the actuating surface.

Description

technical field [0001] The invention relates to a rotary regulator with: a fixed part (stator) on which a capacitive sensor surface is arranged; The operating surface of the type sensing surface. Background technique [0002] Rotary actuators with integrated capacitive sensors are known in principle. For example, DE 10 2004 010 406 B3 describes an information and entertainment system with a rotary actuator integrated with a touch-sensitive surface. In this case, the touch-sensitive surface can in particular be embodied as a touch screen and be provided as an input device for handwriting recognition. Of course, this document does not disclose the details of the structural design of the touchscreen and the rotary actuator here. [0003] For the configuration of the touch-sensitive surface on the rotary adjuster, it is expedient to arrange the electrical components on the fixed part, in particular so that the electrical connection of these elements does not limit the rotatio...
