Operating unit for a device, in particular for a vehicle component
The operating unit for a device, particularly for a vehicle component, is provided with a housing that has an operating panel and is provided for attachment in an apparatus, particularly a vehicle dashboard or vehicle center console, the operating panel being elastically mounted on the housing. Further, an actuator for mechanically exciting the operating panel when use of the operating panel is detected is provided. Finally, the operating unit also has a vibration compensation mass that is mechanically excitable by the or by an actuator when use of the operating panel is detected and is elastically mounted in and/or on the housing and is movable to essentially compensate for a motion of the housing when the actuator mechanically exciting the operating panel is activated. The operating unit has a backlit display that has a display unit and a backlight unit separate therefrom. The backlight unit serves as a vibration compensation mass.
1. An operating unit for a device, comprising:
a housing which comprises an operating panel and is provided for attachment in a vehicle dashboard or vehicle center console, the operating panel being elastically supported at the housing;
an actuator for mechanically exciting the operating panel when an operation of the operating panel is detected; and
a balance weight, wherein:
the balance weight is mechanically excitable by the or by an actuator when the operation of the operating panel is detected,
the balance weight is elastically supported in and/or at the housing and/or is elastically supported at the operating panel,
the balance weight is movable to compensate for forces acting on the housing when the operating panel is mechanically excited,
the operating panel is designed as a front side of a display unit that is elastically supported at the housing, and
the balance weight is designed as a backlight unit for backlighting the display unit.
2. The operating unit of claim 1 , wherein the movement strokes of the display unit and the backlight unit, when excited by the actuator or the actuators, are configured or determined as a function of the relation between the respective masses of the display unit and the backlight unit and/or the relation between the position of the centers of mass of the display unit and the backlight unit and/or the spring damper elements of the respective elastic supports of the display unit and the backlight unit at the housing and/or the magnitude of the vectorially oppositely directed movement stroke components or movement strokes of the display unit and the backlight unit.
3. The operating unit of claim 1 , wherein a common actuator is provided for moving both the display unit and the backlight unit, the actuator comprising length-variable actuator element with two ends averted from each other, the distance between the ends being variable by movement in opposite directions and one end being operatively connected with the display unit and the other end being operatively connected with the backlight unit for mechanical excitation of the display unit and the backlight unit.
4. The operating unit of claim 1 , wherein the actuator or the actuators operates/operate electromechanically or piezo-electrically.
5. The operating unit of claim 2 , wherein a common actuator is provided for moving both the display unit and the backlight unit, the actuator comprising length-variable actuator element with two ends averted from each other, the distance between the ends being variable by movement in opposite directions and one end being operatively connected with the display unit and the other end being operatively connected with the backlight unit for mechanical excitation of the display unit and the backlight unit.
6. The operating unit of claim 2 , wherein the actuator or the actuators operates/operate electromechanically or piezo-electrically.
7. The operating unit of claim 3 , wherein the actuator or the actuators operates/operate electromechanically or piezo-electrically.
