Problems solved by technology

However, unlike tactile-generating devices constructed in a mechanically positioned manner, it is found to be disadvantageous in this rotary actuator that the zero position of the rotary actuator is relatively unstable (weich) and due to the fact that the motor must be applied when turning the handle. Reaction torque, adjustment vibration can be felt

Embodiment Construction

[0012] The rotary adjuster shown in the drawing is accommodated, apart from a rotary knob 1 for manual actuation, in a housing 2 , which is shown partially open in FIG. 1 . The adjusting shaft 3 rotatably supported in the housing 2 passes through the top surface of the housing 2 and connects the knob 1 with the tactile generating device, which is constructed in the form of mechanical positioning and mainly includes an annular positioning cam 6 and two A spring-loaded positioning pin 5, 5' embedded in the positioning cam. These two positioning pins 5, 5' are mutually supported by the compression spring 4, and are arranged opposite to each other in a sleeve-shaped receiving body that is connected to the adjustment shaft 3 and is arranged perpendicular to the axis of rotation of the adjustment shaft. The positioning cam 6 is formed on the inner side of an annular body 7 which is mounted rotatably in the housing 2 about an axis which coincides with the axis of rotation of the adju...

Abstract

The invention relates to a rotating actuator comprising a rotatably mounted control stick (3) and a rotary knob (1) which is connected thereto, in addition to a device for generating a haptic perception when rotating the rotary knob (1). Said device is provided in the form of a mechanical detent and comprises a detent curve (6) and at least one detent element (5, 5') which engages in the detent curve (6). The invention is characterised in that the haptic perception generating device is assigned to an actuating device which is driven by an electromotor (8), by means of which the haptic perception generating device can be subsequently rotated by operating the electromotor (8) of the rotary knob (1) which is connected thereto by means of the control stick (3).

Description

technical field [0001] The invention relates to a rotary regulator with a rotatably mounted adjusting shaft and a knob connected thereto, and with a device for generating a tactile sensation when the knob is rotated, wherein the device is designed in the form of a mechanical positioning and includes a positioning cam and at least one positioning pin embedded in the positioning cam. Background technique [0002] For example, rotary actuators are used in data input devices, wherein by rotating the rotary actuator and optionally by pressing or deflecting the rotary actuator, the cursor can be controlled in different menu surfaces. Such a rotary adjuster can be part of a so-called joystick, for example. Such a rotary regulator is known from DE 19712 049 A1. In this known rotary adjuster, a device for generating a tactile sensation is coupled to the adjusting shaft by means of a transmission. This device is an electric motor which applies a correspondingly loaded torque to the...
