Definitions
- the invention relates to an operating element such as is preferably used in a vehicle, in particular a motor vehicle, a rail vehicle, an aircraft or a watercraft.
- the invention is based on the object of providing an operating element that allows the least possible distraction of a user.
- an operating element comprising a magnetorheological material, with at least one driver arrangement for generating a changeable magnetic field.
- a change in the feel of the operating element can be generated by a change in the magnetic field. This can be brought about in particular by changing the shape of the control element and / or by changing the rigidity of the control element. In this way, communication with a user of the operating element can be achieved without the user having to look at the operating element himself and thus being distracted.
- the magnetorheological material can be a magnetorheological elastomer or a magnetorheological fluid.
- a magnetorheological elastomer contains magnetorheological material that is dispersed in the elastomer. In most cases, it is carbonyl iron powder that is homogeneously dispersed in the elastomer.
- the magnetorheological material can also be dispersed with a specific texture. Under the influence of a magnetic field, the magnetorheological elastomer aligns itself in the direction of the field.
- the magnetic field leads to an elongation in the longitudinal direction of the coil or to a cross-sectional reduction in the transverse direction of the coil. This results in a corresponding change in shape that can be grasped by a user as a changed haptic.
- magnetorheological material is designed as a magnetorheological fluid, then it goes without saying that this material is accommodated in a sealed manner in the cavity of an elastomer.
- a change in the magnetic field only leads to a change in the viscosity and thus the rigidity of the switching element, but not to a change in shape.
- the change in stiffness can also be detected by a user as changed haptics.
- the driver arrangement is designed to generate a vibration of the operating element, in particular with different frequencies perceptible by the operator, different duration and / or intermittent output.
- a user could be indicated by a vibration when a correct entry has been made, for example the entry of a telephone number has been completed.
- it could be indicated to a user by different frequencies whether, for example, an input should be made to increase a certain value or to decrease a certain value.
- different frequencies can be used to give a user specific feedback or specific requirements for an input.
- different durations and / or intermittent outputs of a frequency can be used to communicate with a user.
- the driver arrangement is designed to allow at least part of the operating element to protrude from a surface when activated or to sink it into a surface.
- control element when it is not needed, the control element can, for example, remain sunk in a surface and only be moved out when an input is required.
- the operating element is preferably designed as a push button or button.
- the operating element comprises a plurality of individual operating elements, each of which has its own driver arrangement.
- the operating element has a magnetorheological elastomer, which is coupled to a coil for generating a changeable magnetic field, the coil being coupled to an electrical switching device and at least one end via a connection with a manually movable one Area is connected to the driver arrangement, the switching device having means for monitoring the magnetic field and / or the capacitance between the two connections in order to trigger a switching process when the manually movable area is activated.
- control element is combined with an electrical switching device.
- the control element is designed in a particularly simple and compact manner, on the one hand to implement a switching device and, on the other hand, to provide a changeable feel in order to be able to communicate with a user.
- An operating element according to the invention can preferably be produced using 3D printing. Almost any shape can be realized in 3D printing, so that the control element can be easily adapted to different applications and requirements.
- an operating element according to the invention can preferably be used to communicate with an operator, for which purpose a change in the feel of the operating element that can be perceived by an operator is used.
- a vibration can be used, for example, to give an operator feedback on activation of the control element or to prompt the operator to make an entry.
- an operating element according to the invention can preferably be used in a vehicle, in particular a motor vehicle, a rail vehicle, an aircraft or a watercraft.

- FIG. 1 a schematic representation of an operating element according to the invention is designated as a whole by the number 10. It is an operating element 10 with a magnetorheological elastomer 12 in the form of a block which is surrounded by a coil 15.
- the magnetorheological elastomer 12 has magnetizable particles that are dispersed in the elastomer matrix. This is mostly carbonyl iron powder that is homogeneously dispersed in the elastomer matrix. A texture can also be present for special applications.
- a driver arrangement denoted overall by 14 comprises a coil 15, a voltage source 20 and a switch 22.
- the voltage source 20 and the switch 22 are preferably electronically controllable.
- the coil can be, for example, a ring coil in a cylindrical, elongated shape, within which the magnetorheological elastomer 12 is enclosed. It goes without saying, however, that various other coil arrangements are also possible.
- the magnetorheological elastomer 12 can be designed not only in block form, as shown, but in almost any shape, which can easily be represented by 3D printing.
- a magnetorheological fluid 13 is provided here, which is sealingly enclosed in a cavity of an elastomer. Otherwise, the construction corresponds to the arrangement according to FIG. 1.
- the operating element 10 or 10a according to FIG. 1 or 2 can be part of a switching element with which, for example, an electrical switch is operated.
- the operating element 10 or 10a can thus be part of a mechanical plunger with which an electrical switch is operated.
- the driver arrangement 14 is used to generate a variable haptic, which can be perceived by an operator, by changing the shape and / or rigidity of the elastomer 12.
- a vibration of the elastomer 12 can be brought about, with different frequencies, a different duration and / or an intermittent output being able to be used in order to exchange certain information with the operator.
- the operating element can also consist of a plurality of individual elements, as is shown schematically in FIGS. 3 and 6.
- the control element 10b according to FIG. 3 consists, for example, of nine individual control elements 26, 27, 28, 29, 30, 31, 32, 33, 34, which are arranged in a checkerboard manner.

- FIG. 4 a further embodiment of an operating element according to the invention is shown and designated as a whole with 10c.
- the operating element 10c is let into a surface 45 and is movable within it.
- a part of the operating element 10c ′ can protrude outwardly from the surface 45.
- Fig. 6 shows another control element designated as a whole by 10d which, in turn, consists of nine individual control elements 26 to 34 arranged in a checkerboard manner.
- Each individual operating element 26 to 34 also has a switching area 47 which, when activated manually, triggers an electrical switching process.
- the non-activated state results in a certain Correct pressure point characteristics, by means of which a switching process can be triggered by manual actuation (fail-safe operation).
- the switching characteristics can be changed and, on the other hand, communication with the user, as described above, can be achieved.
- a further control element is shown as an example, which is designated as a whole by 10e.
- This is an operating element in which, on the one hand, an electrical switching element 50 is implemented and which, on the other hand, is combined with a magnetorheological elastomer 12 in order to generate a variable feel.
- the coil 15 is connected via a flat connection 16, which has the switching area 47 protruding outwardly.
- the coil 15 is connected to the driver arrangement 14 via a connection 18.
