Description

The invention relates to a switch panel according to the preamble of patent claim 1.

Such a switch panel may have one or more switching elements for manual operation. The switch panel, which is preferably equipped with a closed surface, can be used in particular in a motor vehicle.

Such a control panel has an actuating surface for manual action by means of an element by the user. In particular, the element may be the finger of a human hand, with the aid of which the actuation of the switching elements of the control panel takes place. The actuating surface acts together with a sensor such that the sensor generates a signal on approach of the element to the actuating surface and / or upon contact of the actuating surface by means of the element and / or pressure of the element by means of the actuating surface. The signal is used for switching and / or triggering a function associated with the respective switching element in the switch operating panel in the manner of a switching signal. It lacks the switch panel, especially in such a closed surface, on a perceivable by the user feel and / or acoustics.

From the DE 10 2008 036 155 A1 Furthermore, a switch panel for a motor vehicle is known in which the signal generated upon actuation of the actuating surface has a haptic Reaction of the actuating surface triggers. For this purpose, an actuator is in operative connection with the actuating surface, wherein the actuated by the signal actuator exerts a lateral, rapidly decaying vibration as a haptic reaction to the actuating surface. The actuator may be an electromagnet having a coil and an armature movable in the coil. When the actuator is actuated, the armature of the electromagnet is moved by appropriate energization of the coil of the electromagnet.

Other switch panels, where a haptic for the actuating surface can be generated, are in the WO 2007/147507 A2 . US 2008/163051 A1 . WO 2008/033710 A2 . US 2007/057928 A1 and EP 1 310 860 A1 described.

The invention has for its object to further develop the switch panel so that a haptic and / or acoustics is created for the switch panel, the haptic and / or acoustics should be performed adjustable.

In particular, the realization of the feel and / or acoustics in control panels with a closed surface without a directly movable switching element, such as an electrical switch, a snap disk o. The like., Which previously produced the feel and acoustics, object of the invention. In previous switch panels, which, however, have no closed surface, conventional, directly movable, electrical switching elements are used, these switching elements then produce the feel and / or acoustics.

This object is achieved in a generic switch panel by the characterizing features of claim 1.

When switching panel according to the invention a haptic and / or acoustic-generating element is provided, wherein the haptic and / or acoustic-generating element is in operative connection with the actuating surface. The signal generated by the sensor activates the actuator for actuating the haptic and / or acoustic-generating element. In a simple and compact arrangement is the haptic and / or acoustic-generating element of a fixed to the actuating surface bracket or attached to the actuating surface fork. When the electromagnet is actuated, the armature of the electromagnet can in turn pull on the yoke or fork and / or hit the yoke or fork. In another arrangement, in which the force curve for the haptics can be varied within a wide range, the haptic and / or acoustic-generating element comprises an adapter that can be longitudinally displaced from the armature of the electromagnet when the electromagnet is actuated and has one end connected to the adapter and with the other end acting on the actuating surface lever. Thus created is a concept for the haptic and / or acoustic feedback by means of an actuator, especially in a switch panel with a closed surface. Advantageously, the concept dispenses with conventional electrical switching elements for the switch panel. Further embodiments of the invention are the subject of the dependent claims.

The armature of the electromagnet in turn actuates the haptic and / or acoustic-generating element. The corresponding energization of the electromagnet generates the accordingly adjustable feel. Various haptic and / or acoustic effects can now be achieved with the aid of the inventive concept. Thus, on the one hand, the actuator can actuate the haptic and / or acoustic-generating element essentially perpendicular to the actuating surface. And preferably so that the haptic and / or acoustic-generating element moves the actuating surface substantially perpendicular to the surface. On the other hand, the actuator can actuate the haptic and / or acoustic-generating element substantially parallel to the actuating surface. And preferably so that the haptic and / or acoustic-generating element moves the actuating surface substantially parallel to the surface thereof. Advantageously, a movement or a vibration of the actuating surface can thus be represented in different directions. Depending on the desired force curve for the feel of the actuator pulling or hitting the operation on the haptic and / or acoustic-generating Interact with the element. With these measures, a different acoustics can be achieved.

In particular, it is in the one arrangement to provide a metal bracket or a metal fork to achieve a special acoustics. Furthermore, an acoustic element may be attached to the bracket or on the fork, to which the armature strikes upon actuation of the electromagnet, whereby a presettable according to the user acoustics is possible.

In an expedient and compact embodiment, the actuating surface comprises a panel and a support member. It is advisable in this case that the carrier part is mounted movably on a reflector, in particular floating. For this purpose, an elastic element in the nature of a soft component can be arranged on the reflector for mounting the carrier part. The reflector also allows reliable illumination of the actuating surface.

In the other arrangement, the lever may continue to be hinged near the other end of the reflector. For example with the help of a nose on other end of the lever can be acted upon in longitudinal displacement of the adapter on the diaphragm support in a corresponding manner.

In a further refinement, a touch-sensitive switching element, a short-stroke button, a snap-action disk or the like can be used to generate the acoustics. However, these conventional switching elements then do not serve as before to generate a switching signal but only to generate the Elkustik. For this purpose, an approach may be arranged on the support part and / or on the adapter, with the aid of which then, when the actuator is actuated, the tactile switching element, the short-stroke key, the snap-action disc or the like is acted upon to generate the acoustics.

Conveniently, the switch panel on a housing for receiving the actuator and the actuating surface, so that the switch panel can be made as a separate, pre-assembled component. The switch panel can then be mounted in a simple manner in the vehicle. The housing may be configured such that the actuating surface constitutes a termination located on one side of the housing and thus forms a substantially closed surface on the housing.

In a further embodiment of the switch panel, a piezoelectric element, in particular based on the direct and / or indirect piezoelectric effect, as a haptic and / or acoustic-generating element and actuator or actuator is provided. The piezoelectric element can be brought into operative connection with the actuating surface such that a haptic effect for the actuating surface can be generated by applying an electrical voltage to the piezoelectric element. Advantageously, the haptics and / or acoustics can be set by appropriate electrical and / or electronic control of the piezo element.

In a simple and functionally reliable design, an actuator may be arranged on the actuating surface. The actuator establishes the operative connection between the actuating surface and the piezoelectric element.

It is also within the scope of this embodiment that the sensor detecting the action of the element on the actuating surface consists of a piezo element, in particular based on the direct and / or indirect piezoelectric effect. The pressure detection on actuation by the operator is then realized with the piezo element, which allows its use as a sensor.

Finally, the piezoelectric element can serve both as a sensor and as a haptic and / or acoustic-generating element together with the actuator. The concept therefore provides for haptic and / or acoustic feedback as well as pressure detection by means of an actuator based on both the direct and the indirect piezoelectric effect. Advantageously, thus, the piezoelectric element can serve as an actuator and / or as a sensor.

For particularly preferred embodiments of the switch panel according to the invention is to be determined below.

As an actuator solenoid is used, which is recorded in the control panel. Upon actuation, the plunger or armature of the electromagnet strikes against a haptic and / or acoustic generating element which is located on the underside of the user interface, e.g. attached to the panel. Thus, the feel and / or acoustics are separated and individually adjustable. Depending on the desired feel and / or acoustics, the electromagnet may have different mounting positions. Also, the modes of action and the directions of action, such as train and / or pressure, may vary.

A piezo element is placed in a control panel, preferably directly on the circuit board. An actuator which is fixedly connected to the user interface, e.g. injected, presses on actuation of the operator on the piezo element and deforms it. Due to the physical principle, namely the direct piezoelectric effect, the element converts mechanical energy into electrical energy. The delivered electrical voltage can be detected, whereby the use is possible as a sensor.

And / or vice versa deforms when applying an electrical voltage, the piezoelectric element mechanically, in accordance with the indirect piezoelectric effect. There are the piezo element emits an acoustic and / or mechanical signal due to the impact. This allows use as an actuator.

Through the use of different materials for the actuator and the change of the control, the haptics and / or acoustics can be adjusted separately and individually.

The advantages achieved by the invention are in particular that a possibility is created to realize the haptic and / or acoustics and / or sensor without conventional switching elements with a movement path. Advantageously, one obtains a control panel with "zero path" and, if necessary, with "zero force". Furthermore, the influence of manufacturing tolerances of the individual components on the feel and / or acoustics is minimized in this system. In addition, a saving of components in the control panel by eliminating the actuator and / or the sensor is given. Finally, the switchboard is also particularly inexpensive.

schematically the operation of a piezoelectric element as an actuator.

In Fig. 1 is a switch panel 1 for a motor vehicle to see with an actuating surface 3, are arranged on the individual areas 2 in the manner of switching elements for triggering and / or operation of various functions in the motor vehicle. For example, the control panel 1 may be one for operating the air conditioning system in the motor vehicle, wherein by means of the switching elements 2, the temperature in the motor vehicle, the ventilation, the windshield fan o. The like. By the user is adjustable. On the actuating surface 3 is for the switching elements 2, a function symbol 9 for displaying the triggerable by means of the switching element 2 function and a Function display 10 for displaying the state (on / off) of the respective function arranged, the function icon 9 and the function display 10 are illuminated.

The control panel 1 has a housing 4, on the upper side of the actuating surface 3 is located. Again Fig. 1 can be seen, the actuating surface 3 has a closed surface, whereby the control panel 1 is largely protected from harmful external influences. The switching elements 2 are actuated by the user by means of an element 11 on the corresponding area 2 of the actuating surface 3 acts manually. The element 11 is in particular a finger of the user's human hand.

How to get in Fig. 2 sees, is located in the housing 4, a printed circuit board 5, on the electrical / electronic components 6, for example light emitting diodes for illuminating the actuating surface 3, are arranged. The actuating surface 3 is in turn arranged on a housing 4, serving as a holder for the circuit board 5 reflector 26. Of the light emitting diodes 6 lead light guide 37 to the function symbols 9 and light guide 38 to the function displays 10 on the actuating surface 3, such that the radiated light from the LEDs 6 for lighting the function symbols 9 and / or the function displays 10 is performed. Based on Fig. 3 one recognizes further that the actuating surface 3 consists of a diaphragm 24, a diaphragm support 25 and a further support member 39.

The manual action of the finger 11 on the actuating surface 3 is detected by means of a sensor. For this purpose, an electrically conductive film 12 is arranged in and / or on the actuating surface 3, by means of which an electric field is generated in the region of the actuating surface 3 by applying an electrical voltage. The actuating surface 3 interacts with the sensor 12 in such a way that the sensor 12 generates a signal when the element 11 approaches the actuating surface 3 by evaluating the change in the electric field due to the approach of the finger 11, in particular the capacitive change.

How to continue the Fig. 3 The film 12 is arranged such that each region 2 on the actuating surface 3 is assigned such a guide region 13. By evaluating the change in the electric field for a single guide region 13, it is also possible to detect the contact of the actuation surface 3 by means of the finger 11, specifically the touch of the respective switching element 2 on the basis of the respective guide region 13. The actuation surface 3 interacts with the sensor 13 in this way in that, when the corresponding area 2 of the actuating surface 3 is touched by the element 11, the sensor 13 generates a signal by evaluating the change in the electric field for the guide area 13 by the touch of the finger 11, in particular the capacitive change.

As further on the basis of Fig. 2 can be seen, a magnet 14 is disposed on the inside of the housing 4 facing side of the actuating surface 3 on a holder 47. The magnet 14 is associated with a Hall sensor 15, which is located on the circuit board 5 in the housing 4. When pressure is applied by means of the finger 11 on the actuating surface 3, the actuating surface 3 bends slightly, so that the magnet 14 is moved accordingly. This movement of the magnet 14 is detected by means of the Hall sensor 15. Thus, the actuating surface 3 cooperates with the sensor 15 such that the sensor 15 generates a signal when pressure is applied to the actuating surface 3 by means of the element 11 by the change of the magnetic field by the magnet 14 is evaluated.

In addition to or instead of the Hall sensor 15, a strain gauge (not shown in detail) can be used as the sensor, to which the bending of the actuating surface 3 acts in a deforming manner. This deformation of the strain gauge causes a change in its electrical resistance. The change in the electrical resistance is then in turn evaluated for the generation of the signal.

The signal generated by the sensors 12, 13, 15 can be evaluated accordingly and then serves for switching and / or triggering the respective function in the motor vehicle in the manner of a switching signal. At least one of the signals generated by the sensors 12, 13, 15 and / or another due to the evaluation of the signals generated by the sensors 12, 13, 15 causes the generation of a haptic and / or acoustics for the switch panel 1. For this purpose, a haptic and / or acoustic generating element 7 (see Fig. 4 ), which is in operative connection with the actuating surface 3. The corresponding signal then controls an actuator 8 for actuating the haptic and / or acoustic-generating element 7.

How to get in Fig. 4 sees, it is the actuator 8 is an electromagnet. The electromagnet 8 has a coil 16 and a movably mounted in the coil 16, acted upon by a spring 48 anchor 17. Now, the actuator 8 is driven, there is a corresponding energization of the coil 16 of the electromagnet 8, which in turn the armature 17 of the electromagnet 8 is moved. The moving armature 17 beats on the leaf spring-like configured haptic and / or acoustic-generating element 7. Due to the impact on the one hand by the haptic and / or acoustic-generating element 7 generates a noise in the manner of a click, which signals the user switching the switching element 2. On the other hand, the impact movement of the armature 17 is transmitted from the haptic and / or acoustic-generating element 7 via an arranged on the inside of the actuating surface 3 plunger 18 on the actuating surface 3, which in turn from the user's finger 11 as a haptic feedback for the switching of Switching element 2 is felt. In this case, the actuator 8 actuates the haptic and / or acoustic-generating element 7 substantially perpendicular to the actuating surface 3, preferably such that the haptic and / or acoustic-generating element also moves the actuating surface 3 substantially perpendicular to the surface thereof.

In a further embodiment, the direction of impact of the lifting magnets 8 in about 180 ° relative to those after Fig. 4 turned around, how to use the Fig. 5 sees. According to Fig. 6 the haptic and / or acoustic-generating element 7 consists of a bracket 19 attached to the actuating surface 3, in the present case of a metal bracket. When the electromagnet 8 is actuated, the armature 17 of the electromagnet 8 moves in the direction of actuation of the finger 11 and strikes the bracket 19, wherein the actuating surface 3 for the haptic is slightly lowered. At the same time a noise is generated at the stop. To improve the acoustics can still on the bracket 19 In addition, an acoustic element 20 may be arranged, on which the armature 17 strikes. How to use the Fig. 5 sees, the control panel 1, two brackets 19 and 8 electromagnets.

In another embodiment according to Fig. 7 Pulling solenoids 8 are used, which pull when energized, the actuating surface 3 in the direction of actuation down. How to continue in Fig. 8 sees, a fork-like configured haptic and / or acoustic-generating element 7 is attached to the inside of the actuating surface 3. In the fork 23 of the Haptikund / or acoustic-generating element 7, the armature 17 of the electromagnet 8 is mounted, whereby the actuator 8 acts pulling to actuate the haptic and / or acoustic generating element 7. Furthermore, on the inside of the actuating surface 3, a lug 21 is arranged, which acts in switching control of the actuator 8 and thereby effected movement of the actuating surface 3 on a Tastschaltelement 22 switching, which generates a clicking noise. Thus, in this case, the haptic for the control panel 1 by means of the haptic and / or acoustic-generating element 7 and the acoustics by means of the Tastschaltelements 22 is generated. Instead of a push-button 22 may also be a short-stroke, for example, has an actuation of about 0.5 to 0.6 mm, a snap-action disc o. The like. Are used to generate the acoustic feedback.

In yet another embodiment according to Fig. 9 and Fig. 10 a solenoid 8 is arranged lying in the housing 4 and pulls the actuating surface 3 in the longitudinal direction. For this purpose, the actuating surface 3 comprises a diaphragm 24, a diaphragm support 25 and a support member 39. The support member 39 is in turn on a reflector 26 movable, and floating, stored. An elastic element 27 in the manner of a soft component is arranged on the reflector 26 for supporting the carrier part 39. The haptic and / or acoustic-generating element 7 consists of a fork 29 mounted on the support member 39 by means of a screw 28 made of metal. When controlling the electromagnet 8, the armature 17 of the electromagnet 8 pulls on the fork 29. The actuator 8 thus actuates the haptic and / or acoustic-generating element 7 substantially parallel to the actuating surface 3, which in turn the haptic and / or acoustic generating element 7, the actuating surface 3 is moved substantially parallel to the surface thereof. The acoustic feedback in the Art a double click is generated by the contact of the armature 17 with the metallic fork 29.

In yet another embodiment according to Fig. 11 the solenoid 8 is again installed lying and pulls the floating bearing actuating surface 3 via a lever 30 in the longitudinal direction. For this purpose, the haptic and / or acoustic-generating element 7 comprises a longitudinally displaceable by the armature 17 of the electromagnet 8 when controlling the electromagnet 8 and the adapter 33 with one end to the adapter 33 by means of a shaft 34 hinged lever 30, as can be seen in Fig. 12 sees. The lever 30 is hinged in the vicinity of its other end on the reflector 26 by means of a slot 31 on a further shaft 35. At the other end of the lever 30 is still a nose 32 is located. Now, if the adapter 33 is moved longitudinally by means of the armature 17, so the lever 30 rotates about its hinges 34, 35 and acts with the nose 32 at the other end on the support member 39 a. As a result, in turn, the actuating surface 3 is moved to produce a feel substantially parallel to the surface thereof. The adapter 33 is acted upon by a spring 36 against the reflector 26 and acts in its movement to produce an acoustics in the manner of a click on a arranged on the reflector 26 Tastschaltelement 22 a

With reference to the described embodiments for the haptic and / or acoustic-generating element 7, it can be seen that the feel and / or acoustics for the control panel 1 can be adjusted within wide ranges in accordance with the wishes of the user. In addition, the following further exemplary measures for the selectable adjustment of the feel and / or acoustics are suitable:

• Material selection,
• Geometry,
• Installation conditions,

• Type actuator,
• Mounting positions as well as interface.

Finally, in a further embodiment, a piezo-element is used as a haptic and / or acoustic-generating element and / or as a sensor. For this purpose, the piezoelectric effect will first be explained in more detail.

As in Fig. 13 is shown for explanation, a pressure on the piezoelectric element 40 by means of a pusher 41 is exercised. In this case, a conversion of mechanical into electrical energy is carried out by means of the direct piezoelectric effect in the piezoelectric element 40. At the piezoelectric element 40 thus an electrical voltage 42 can be tapped. The direct piezoelectric effect is used in sensors, piezo ignitors, energy harvesting or the like. As in Fig. 14 is shown, an electrical voltage 42 is applied to the piezoelectric element 40. In this case, by means of the indirect piezoelectric effect in the piezoelectric element 40, a conversion of electrical into mechanical energy is performed. Thus, the piezoelectric element 40 generates a force 43. The indirect piezoelectric effect is used in fast actuators.

In Fig. 15 is the switching panel 1 using a piezo element closer to see in a schematic diagram. The switch panel 1 has a housing 4, on which an actuating surface 3 is arranged for manual pressure by the user. A sensor 44 is in operative connection with the actuating surface 3 for detecting the action on the actuating surface 3. The sensor 44 consists of a piezoelectric element, in particular based on the direct and / or indirect piezoelectric effect described above.

The piezoelectric element 44 can also serve as a haptic and / or acoustic-generating element and actuator, in particular based on the direct and / or indirect piezoelectric effect. The operation of such, realized by means of a piezoelectric element, electrically and / or electronically controllable actuator 44 for exerting a force F on a component 46, wherein the component 46 is then in turn correspondingly movable by the force F is in Fig. 16 shown.

As further on from Fig. 15 can be seen, the piezoelectric element 44 can be brought into operative connection with the actuating surface 3 for the haptic and / or acoustic generation, so that by applying an electrical voltage to the piezoelectric element 44, a haptic effect for the actuating surface 3 can be generated. It is advisable that these two functions are shared, with which the piezo-element 44 serves as a sensor and as a haptic and / or acoustic-generating element together with actuator. In this case, the piezoelectric element 44 generates as a sensor the signal with a corresponding action on the actuating surface 3. The signal then controls the piezoelectric element 44 to produce a feel for the actuating surface 3 and / or acoustics. In the housing 4 is a circuit board 5, on which the piezo-element 44 is arranged An actuator 45 is disposed on the actuating surface 3, such that the actuator 45, the operative connection between the actuating surface 3 and the piezo-element 44 produces.
