Definitions

  • the present invention relates to an operating element, in particular for a motor vehicle, with a freely programmable symbolism.
  • System status assigned a variable meaning In order to indicate to the user the meaning currently assigned to the operating element, it is known to make the symbolism displayed on the operating element freely programmable.
  • the published patent application DE 103 42 142 A1 discloses a control element with freely programmable symbols, in which the light of a light source is parallelized by means of a lens and transmitted through a display. The light then hits the key cap of the control element, where it is perceived by the user.
  • a disadvantage of this solution is the necessary space for parallelizing the light space. It is therefore an object of the present invention to provide a control element with programmable symbolism, which is simple in construction and easy to manufacture and requires only a small space.
  • control element according to the invention with a freely programmable symbolism for a motor vehicle has a movably received in a housing, transparent keycap, a light source disposed in the control element, a means for parallelizing the emitted light from the light source and a soulichtuchtbares from parallelized light, programmable display element, wherein the display element is arranged behind the transparent key cap, that the symbolism represented by the display element is projected onto the transparent key cap, the means for parallelizing the light is designed as a concave mirror and the light source is arranged between the display means and the concave mirror.
  • the light source is preferably arranged in the focal point of the concave mirror.
  • the transparent key cap is preferably made of plastic.
  • the concave mirror consists of a reflective coated carrier material.
  • the support material is concave in the manner of a conventional concave mirror. Alternatively, that represents
  • Support material is a block of any shape with a curved shape.
  • the concave mirror may consist of a light block with integrated or behind the light stone reflection layer.
  • a light stone is a transparent light guide.
  • the beam path can be further optimized, for example, produce a parallel beam with even smaller size.
  • the display element is designed as a liquid crystal display (LCD). LCDs are inexpensive standard components that ensure good image quality at low cost.
  • At least one light-emitting diode is used as the light source.
  • An LED is characterized by a low power consumption and a correspondingly low heat development.
  • LEDs can be realized very compact, so they can be considered approximately as a point source of light. The smaller the spatial extent of the light source, the lower the divergence of the reflected radiation behind the concave mirror. A small divergence, ie a light bundle that is as parallel as possible, increases the imaging quality of the LCD.
  • the light source consists of several LEDs.
  • each LED emits light of a different color, preferably a primary color.
  • any color mixtures can be generated. If a red, a green and a blue LED is used, additive color mixing can cover a wide range of colors.
  • the operating element has a scattering film for scattering the light of the light source transmitted through the display element. Since the light guided through the display element is as parallel as possible, as described above, it usually has to be deflected in order to be visible from different viewing directions. This is done by means of a scattering foil, which scatters the light in a defined angular range. This angular range is preferably kept as large as possible so that, for example, both the driver and the passenger of the motor vehicle can recognize the symbolism. Alternatively, a scattering angle range is possible, which preferably covers the head of the driver of the motor vehicle.
  • the operating element has a light block arranged behind the display element with respect to the beam path.
  • the display element is oriented such that the parallel light beam is not perpendicular to the surface of the display element. This makes it possible to exploit the fact that a display element, in particular an LCD, has different imaging properties depending on the angle of incidence of the incident light, for example with respect to the contrast.
  • This control element 1 has an LED 2, a concave mirror 3 and an LCD 4.
  • the concave mirror 3 is a plastic support with a convex mirrored surface 9.
  • the LED 2 is arranged in a region between the LCD 4 and the concave mirror 3, preferably in the focal point of the concave mirror 3.
  • a divergent beam cone 8 goes out, which strikes the curved surface 9 of the concave mirror 3 and is reflected as a parallel or approximately parallel beam 8 '.
  • the beam 8 ' penetrates the LCD 4, which is controlled by a control device, not shown here, such that it shows a desired symbolism.
  • the symbol displayed on the LCD 4 is projected onto the key cap 7 by the parallel beam.
  • a light block 5 is arranged. This consists of a transparent light guide with a high refractive index, which retains any residual divergence of the beam 8'. decreases.
  • the transmitted through the display 4 and the light brick 5 light radiation strikes a scattering film 6, which scatters the light so that it can be perceived by an operator of the control element 1.
  • the scattering film 6 is arranged either on the light stone 5 or the key cap 7. For the operator of the control element 1 creates the impression as if the symbolism on the key cap 7 is shown. It is particularly advantageous that the darg Congress symbolism by programming the LCD 4 is changeable.
  • an operating element 1 may be any type of control, such as a button, a turntable or a combination of both.
  • the LED 2 and the concave mirror 3 are fixed relative to the operating element 1.
  • the LCD 4, the light stone 5 and the scattering film 6 are firmly connected to the key cap 7 and therefore movable together with the key cap 7 relative to the operating element 1. This is particularly advantageous when it comes to the control element 1 is a button.
  • the LCD 4 and / or the light block 5 and / or the scattering film 6 may be arranged stationarily relative to the operating element 1, which is advantageous in particular when the operating element 1 is a turntable.
