Touch-sensitive display device with an integrated mechanical operating part for motor vehicles
View Patent ↗The invention relates to a touch-sensitive display device with an integrated mechanical operating part for motor vehicles, in which a mechanical operating part ( 2 ) and a holding magnet ( 3 ) are provided. The operating part ( 2 ) is held by magnetic force on the surface of a touch-sensitive display device ( 1 ), whereby sensor elements ( 5 ) are provided under the surface of the display device ( 1 ), and that the switching positions of the operating part ( 2 ) can be determined by the sensor elements.
1. A touch-sensitive display device for motor vehicles comprising:
a touch sensitive display for motor vehicles;
a mechanical operating part;
a holding magnet whereby said operating part is held by magnetic force on the surface of said touch-sensitive display; and
a sensor element under the surface of said touch-sensitive display, and wherein said sensor element determines the switching positions of the operating part;
at least two drives capable of moving said mechanical operating part on the surface of said touch sensitive display; and
wherein said mechanical operating part moves automatically to pre-selected positions on the surface of the touch-sensitive display device with said drives and implements gestural display effects through motions.
2. The touch-sensitive display device of claim 1 wherein said holding magnet ( 3 ) is a permanent magnet.
3. The touch-sensitive display device of claim 1 , wherein the said holding magnet ( 3 ) is an electromagnet.
4. The touch-sensitive display device of claim 1 , wherein said mechanical operating part ( 2 ) can be removed from the display device ( 1 ).
5. The touch-sensitive display device of claim 1 , wherein said removable mechanical operating part ( 2 ) assumes the safety function of a key.
6. The touch-sensitive display device of claim 1 , wherein said mechanical operating part ( 2 ) is configured as a push button ( 14 ).
7. The touch-sensitive display device of claim 1 , wherein said mechanical operating part ( 2 ) is configured as a rotating knob.
8. The touch-sensitive display device of claim 1 , wherein said mechanical operating part ( 2 ) is capable of moving to pre-selected positions on the surface of the touch-sensitive display device ( 1 ) and control signals are triggered by the motions.
9. The touch-sensitive display device of claim 1 , wherein said mechanical operating part ( 2 ) is configured as a slider, capable of sliding along the surface of said touch-sensitive display.
10. The touch-sensitive display device of claim 1 , wherein said mechanical operating part ( 2 ) is configured as a short-stroke lever, and capable of pivoting about an axis.
11. The touch-sensitive display device of claim 10 , wherein said axis is substantially parallel to said touch-sensitive display.
12. The touch-sensitive display device of claim 10 , wherein said axis does not pass though said touch-sensitive display.
13. The touch-sensitive display device of claim 1 , wherein said motions of the operating part ( 2 ) are received by means of an optical system including a photosensor ( 12 ) and an optical waveguide ( 11 ), and converted into control signals.
