- FIG. 3 is a sectional view of an operating device according to a third embodiment of the invention.
- FIG. 4 is a sectional view of an operating device according to a fourth embodiment of the invention.
- Figure 5 is a perspective view of an exemplary surface acoustic wave sensor as may be used for the operating devices of the invention.
- FIG. 1 a first embodiment of an operating device is shown with push-button function.
- the operating device includes a control panel 10 made of a plastic material.
- the control panel 10 has a user facing user side 10a (top of FIG. 1) and an inner side 10b facing away from the user (bottom of FIG. 1).
- the operating device has three actuating elements in this embodiment. These are formed in this embodiment by elastically deformable portions 12 of the control panel 10. That the actuating elements are an integral part of the control panel 10, which is formed at least in the region of the actuating elements of a flexible plastic material and in a suitable layer thickness.
- the elastically deformable portions 12 are preferably marked on the user side 10a of the control panel 10 (e.g., by imprinted symbols and / or color), so that they are identified as operating elements for the user.
- On the inner side 10b of the control panel 10 a plurality of wirelessly interrogatable, passive surface wave sensors 14 are provided, each elastically deformable portion 12 of the control panel 10 is associated with at least one such surface wave sensor 14.
- the surface acoustic wave sensors 14 each form a sensor for detecting a deformation of the respective section 12 by a force 16 by a user on the user side 10 a of the control panel in the region of the elastically deformable section 12.
- the surface acoustic wave sensors 14 are integrated in the control panel 10. This can be done for example by means of assembly injection molding ("overmolding", “assembly molding”) in a process step in the manufacture of the control panel 10.
- the control device further includes a control device 16 for actuating the surface wave sensors 14 and evaluating the measurement signals obtained from the surface wave sensors 14.
- the control device 16 is equipped with a transceiver 18 which communicates wirelessly with the surface acoustic wave sensors 14 by radio.
- the construction of a surface wave sensor 14, as it can be used for the described operating device, is shown by way of example in FIG.
- the surface acoustic wave sensor 14 has a base body 30 having piezoelectric properties, for example, a piezoelectric single crystal.
- a transducer 34 which serves as an input transducer and output transducer in this example, and a plurality of reflectors 36 are provided.
- the transducer 34 is also connected to an antenna 32.
- the transceiver 18 of the controller 16 transmits a polling pulse 38 received by the antenna 32 of the surface acoustic wave sensor 14.
- the electromagnetic interrogation pulse 38 is converted by the transducer 34 due to the piezoelectric effect of the base body in mechanical waves / surface acoustic waves, which run over the base body 30 and reflected at the reflectors 36. Due to the piezoelectric effect of the base body, the transducer 34 converts the reflected waves back into a corresponding electromagnetic response signal 40, which is received by the transceiver 18 of the control device 16 as a measurement signal.
- the response signal 40 is a pulse sequence that depends on the arrangement of the reflectors 36 and the propagation of the waves on the base body 30.
- the section 12 When a force 26 acts on the section 12 of the control panel 10, the section 12 deforms. The deformation of the section 12 exerts a corresponding pressure on the base body 30 of the associated surface acoustic wave sensor 14. As a result, the propagation of the waves on the base body 30 changes, whereby ultimately the response signal 40 generated by the transducer 34 changes. For example, the pause times between the pulses of the response signal 40 are changed by changing the propagation speed of the waves on the base body 30. From the change of the response signal 40, the control device can then close to an actuation of the actuating element 12 of the operating device 10.
- the surface wave sensors 14 differ in the arrangement and / or position and / or number of their reflectors 36, so that the control device 16 receives the signals received from the transceiver 18.
- the control device 16 can differentiate responsive response signals 40 of the various surface acoustic wave sensors 14 and thus can distinguish which of the multiple actuators 12 has been actuated by the user.
- the response signals 40 of the various surface wave sensors 14 differ in particular in the pulse sequences and the time intervals of the pulse sequences to the interrogation pulse.
- Fig. 2 shows a second embodiment of an operating device with push-button function.
- the same or corresponding components are identified with the same reference numerals as in the first exemplary embodiment.

- the connecting elements 20 are, for example, carrier foils or punched lattice girders.
- the surface acoustic wave sensors 14 have to be individually inserted into an injection mold in order to integrate them into the control panel 10 by means of assembly injection molding.
- the plurality of surface acoustic wave sensors 14 can be simplified and possibly automated as a common sensor array be inserted into the injection mold.
