Definitions
- the invention relates to an operating device, in particular for a vehicle, in particular a motor vehicle, with an operating element which can be actuated by a user and which is movably mounted on a carrier element, with at least one controllable actuator which is designed to move the operating element relative to the carrier element, and with a spring device which is arranged between the operating element and the carrier element and movably supports the operating element on the carrier element.
- Control devices of the type mentioned are already known from the prior art.
- vehicle construction there are already numerous operating devices for every type of electrical or mechanical device, which are increasingly being replaced by screens with virtual operating elements. Examples of this are outside of the vehicle area, hotplates, copiers, mobile phones, and in the vehicle area, in particular, navigation and multimedia systems.
- haptic feedback is felt by the user with real/mechanical switching devices.
- haptic displays which, when touching a user interface, use at least one actuator to perform a specific movement or vibration, which depends, for example, on the location of the touch, a direction of movement and/or the force of the touch are dependent. As a result, the user is given haptic feedback when operating the operating device.
- Such an operating device is also known, for example, from the publication US 9,436,341 B1 known.
- the user interface is formed by an operating element that is movably mounted on a carrier element by a spring device.
- An electromagnetic actuator is arranged between the carrier element and the operating element in order to move the operating element relative to the carrier element if necessary, in order to thus generate the haptic feedback.
- the direction of movement and the vibrations that occur can lead to airborne noise and/or structure-borne noise, which can reduce comfort.
- an operating device which has an operating element and a compensation element, the operating element and the compensation element being connected to one another by an actuator.
- the operating device also has a single spring device, by means of which both the operating element and the compensation element are movably mounted on a carrier element.
- the operating device with the features of claim 1 has the advantage that the occurrence of structure-borne noise or airborne noise is reduced in a simple and cost-effective manner.
- a compensation element is movably arranged on the carrier element and the actuator is connected to the operating element and to the compensation element.
- the actuator interacts both with the control element and with the compensation element.
- actuation of the operating element by the actuator also affects movement of the compensation element.
- This also allows movements to be transferred from the operating element to the compensation element.
- the compensation element can oscillate in the transverse, inverse direction of movement to the operating element, as a result of which structure-borne noise and/or airborne noise can be compensated for.
- the transmission behavior between the oscillating mass of the control element and that of the compensation element is preferably matched to one another so that the dynamic forces cancel each other out (superposition principle).
- the compensation element is preferably arranged on that side of the carrier element which faces the operating element.
- the operating element is arranged or mounted on the side of the carrier element facing away from the carrier element.
- a second spring device is arranged between the compensation element and the carrier element, which supports the compensation element on the carrier element.
- the spring device creates an oscillatable operating mass system with the operating element and an oscillatable compensation mass system with the compensation element, which are in particular matched to one another by adapting the mass and spring stiffness in such a way that the generation of airborne noise and structure-borne noise is minimized or completely prevented.
- a degree of damping and/or degree of acceleration is also set by the design of the spring devices and the compensation element and the operating element.
- the compensation element and the operating element can preferably be displaced only perpendicularly or only almost perpendicularly to a longitudinal center plane of the carrier element. In this way, the compensation element and the operating element can be moved at least essentially only perpendicularly towards one another or away from one another. Sideways movements are at least largely ruled out. This ensures that, on the one hand, the operating element is guided securely, which gives the user a valuable feeling, and, on the other hand, that the effects of the spring devices can be optimally utilized in order to achieve the desired effect.
- the operating element has a touch-sensitive screen.
- the operating element carries a display which is covered by a transparent protective pane and which includes means for recognizing/detecting the position of at least one finger on the protective pane.
- it can be a capacitive display.
- other embodiments of the touch-sensitive screen are also conceivable. Due to the mobility of the screen and the controllable actuator, it is now possible to haptically convey to the user switching a virtual switch shown on the display. If, for example, the actuator is actuated, the control element and the actuator element are moved towards one another in order to thereby simulate a switching process for the user and to offer haptic feedback.
- the compensation element is preferably a compensation mass.
- the compensation element is thus distinguished solely by its mass, and for this purpose it is preferably manufactured from a stable, one-piece mass element. By skilfully determining the mass of the compensation mass as compensation for the operating element, the vibrations can be compensated for in a particularly advantageous manner.
- the compensation element is preferably designed as a lighting device for the operating element.
- the compensation element preferably has one or more lamps, which are distributed on a substrate or carrier of the compensation element and are aligned towards the back of the operating element in order to illuminate the operating element from behind or from the direction of the carrier element.
- the support element is preferably transparent in sections or provided with openings in order to ensure that the light generated by the lighting device reaches the operating element.
- the lighting device serves as a compensation mass for the operating element and is preferably matched to the mass of the operating element.
- the operating element and the compensation element in particular the lighting device, have at least essentially the same weight. In this way, an advantageous avoidance of vibrations or airborne noise and/or structure-borne noise is achieved.
- the quotient of spring stiffness and mass of the oscillatable systems is preferably the same.
- the compensation element and the second spring device form an oscillatable system and the operating element and the first spring device form another oscillatable system.
- the actuator and the spring devices are designed in such a way that the compensation element and the operating element can be controlled by the actuator with the same force value in opposite directions or in phase opposition. This results in a particularly advantageous reduction in structure-borne noise and/or airborne noise.
- the user can easily perceive the activation of the operating element by the actuator.
- the first spring device and/or the second spring device have at least one spring element, in particular a plurality of spring elements arranged in particular in a uniformly distributed manner.
- the spring elements define the respective spring stiffness or elasticity of the respective spring device and ensure, in particular with a uniform distribution, that the control element and compensation element are uniformly subjected to spring force and thus a uniform movement of the control element and compensation element distributed over their surface area is ensured.
- At least one spring element is preferably an elastomer or foam spring element. This type of spring element is inexpensive and can be easily integrated into the operating device in terms of construction.
- At least one spring element is a metal spring element or plastic spring element, in particular in the form of a spring tongue. So is for example, at least one of the spring elements is integrated into the operating element or into the compensation element.
- the substrate of the lighting device can have one or more spring tongues, which are designed as spring tongues that are cut free and bent out and that implement the spring effect of the spring device through their inherent elasticity.
- the actuator is preferably designed as an electromagnetic actuator or as a piezo actuator. This ensures a cost-effective and space-saving implementation of the actuator in the operating device, which also allows rapid actuation of the operating element.
- the actuator is arranged centrally between the operating device and the compensation element, seen in a plan view of the operating element, so that the actuator force produced by the actuator acts evenly on the operating element and the compensation element.
- several actuators are arranged between the operating element and the compensation element, with the actuators preferably being arranged in a uniformly distributed manner in this case in order to ensure a uniform application of force to the operating element and the compensation element here as well.
- the electromagnetic actuator has a first actuator element arranged on the operating element and a second actuator element arranged on the carrier element.
- the actuator is thus designed in at least two parts, with the actuator elements being designed in such a way that they interact with one another when the actuator is activated, in particular attracting or repelling, in order to pull the operating element towards the compensation element or to repel it.
- At least one of the actuator elements has at least one energizable coil for generating a magnetic field.
- a magnetic field is generated, by which an actuator element is repelled or attracted to the other actuator element of the same actuator.
- there is an air gap between the actuator elements when the control device is in the non-actuated state which allows the control element to be moved from the non-actuated position to an actuation position applied to the compensation element or the carrier element can be pulled by the actuator.
- the vehicle according to the invention with the features of claim 14 is characterized by the operating device according to the invention. This results in the advantages already mentioned.

- the operating element 2 has a touch-sensitive screen 6 with a protective screen 7 .
- a compensation element 8 is movably mounted on the carrier element 3 and is connected to the carrier element 3 by a second spring device 9 .
- the second spring device 9 has a plurality of spring elements 10 which are distributed evenly over the circumference of the compensation element 8 in order to ensure a uniform movement or loading of the compensation element 8 .
- the compensation element 8 is arranged on the side facing away from the operating element 2 of the carrier element 3, so that the carrier element 3 between the compensation element 8 and the Operating element 2 is located and extends there in particular flat. According to an alternative exemplary embodiment, not shown here, the compensation element 8 is arranged on the side of the carrier element 3 facing the operating element 2 .
- the carrier element 3 is itself preferably coupled by viscoelastic damping elements 11 to a dashboard of the motor vehicle, for example.
- the damping elements 11 reduce vibrations that are introduced from the outside, for example vibrations that are caused by a road surface along which the motor vehicle is moving.
- uncompensated vibrations of the operating device itself are reduced, for example tilting movements occurring around the Y-axis.
- the operating device 1 also has a number of actuators 12 which are arranged between the operating element 2 and the compensation element 8 and also act between them.
- each of the actuators 12 has a first actuator element 13 which is connected to the operating element 2 on its rear side facing the carrier element 3 , and a second actuator element 14 which is connected to the compensation element 8 .
- the actuator elements 13 and 14 are each spaced apart from one another, so that an air gap 15 remains between them. At least one of the actuator elements 13 or 14 is provided with an energizable coil which, when energized, generates a magnetic field by which the opposite actuator element 14 or 13 is attracted or repelled. By activating the respective actuator 12, the operating element 2 can be moved relative to the carrier element 3, in particular in the direction of the carrier element or away from it. By controlling the actuators 12, a haptic feedback can thus be generated, which the user of the operating device 1 can feel in particular when operating the touch-sensitive screen 6.
- the operating element 2 and the compensation element 8 are guided in particular on the carrier element 3 in such a way that they only face one another or away from each other and thus at least essentially only perpendicular to the longitudinal center plane of the carrier element 3 are movable.

- a first oscillatable mass results from the touch-sensitive screen 6 with the protective pane 7 and the electronic components arranged thereon, and a second oscillatable mass results from the compensation element.
- a favorable vibration frequency range of the masses moving transversely toward one another is 10 Hz to 300 Hz.
- a resonant frequency of 115 Hz for the respective movable mass is selected.
- This resonance frequency has proven to be favorable in previous tests because the resonance point is in the middle of the haptically perceptible range.
- the required value of the spring stiffness k of the spring elements 5, 10 or of the spring devices 4, 9 in the X-direction of 506 N/mm in the present case is preferably determined from the mass and resonance frequency.
