Problems solved by technology

If the known tactile operating elements, for example for so-called touch screens, are to be used, for example, in environments subject to very large temperature differences, for example if they are used to maintain their functionality regardless of arctic cold or summer heat In vehicles, such haptic operating elements require a large installation space, expensive drives and special construction methods

Embodiment Construction

[0015] exist figure 1 identified in the following: a first ferromagnetic planar part 1 with a raised portion 1 a; a second ferromagnetic planar part 2 with raised parts 2 a; a first printed circuit board 3 with a flat coil 4 in which twelve Two segments 4 a are represented by individual coils; second printed circuit board 5 with second flat coil 6 in which twelve segments 6 a are likewise represented by individual conductor tracks of the second flat coil. The bead 1 a of the ferromagnetic planar part 1 simultaneously acts as the coil core of the first flat coil 4 , and the bead 2 a of the second ferromagnetic planar part 2 acts as the coil core of the second flat coil 6 . When the first flat coil and the second flat coil are energized, there is a magnetic field respectively in the first ferromagnetic planar part 1 and in the second ferromagnetic planar part 2: thus the ferromagnetic planar parts 1, 2 and the flat coil 4, 6 The generated electromagnetics attract or repel each ...

Abstract

An operator control apparatus has an operator control element with haptic feedback. The operator control element has an input area and can be operated by an operator using an input member. The operator control apparatus includes a first and second ferromagnetic areal components and a first and second flat coils that are arranged between the first and second components. The first and second components have their largest areas oriented toward each other and are configured to move relative to each other. The input area is either configured as a part of the first or second component or coupled to the first or second component using a coupling apparatus. The first coil is associated with the first component and the second coil is associated with the second component such that a flow of current through the first and second coils causes the first and second components to move.

Description

technical field [0001] The invention relates to an operating device having an operating element with tactile feedback, wherein the operating element can be actuated by an operator by means of an input organ. Background technique [0002] Tactile feedback of the operating element is required in particular when the operator cannot directly perceive the operating process being carried out by him. While in the case of operating devices with electromagnetic switches the operator can perceive the opening and closing of the switch contacts by means of a changing tactile sensation of the operating part, this is not necessarily the case for electronic switches. An operating element is therefore known in the prior art which, by means of a movement of the operating element which can be felt by the operator, gives tactile feedback about the operating process carried out. If the known tactile operating elements, for example for so-called touch screens, are to be used, for example, in en...
