Definitions

  • the invention relates to a cover element and a cavity cover with such a cover element for covering a cavity in a vehicle.
  • cover elements and cavity covers for vehicles are known from the prior art. These are usually simple covers for covering various cavities, such as glove compartments, storage compartments and tank or loading accesses in or on a vehicle.
  • a narrow decorative part is also known, which has lighting means, so that symbols and the like could in principle be displayed by controlling the lighting means.
  • trim part In addition to the lack of usability of such a trim part, there is also the fact that the trim part cannot be used to represent different lighting scenarios and, for example, to change light colors or light intensities, which is of great importance in modern vehicles, in order to offer the user a high degree of individualization or to enable situation-dependent lighting.
  • the invention is therefore based on the object of overcoming the aforementioned disadvantages and providing a cover element and a cavity cover with such a cover element, which not only requires little space but also allows different colors to be displayed.
  • a cover element is therefore proposed for covering a cavity on a vehicle, ie in the vehicle or on the outside of the vehicle, the cover element having an electronic control unit.
  • the covering element can in particular be used for covering of cavities, in and on the vehicle.
  • a glove compartment, a tank or loading access or storage compartments can be covered with such a cover element.
  • the covering element also has a carrier layer and, towards one visible side, a decorative layer with a surface which is curved at least in sections on the visible side and which follows a predetermined surface profile.
  • the surface is therefore in particular designed as a free-form surface, convex, concave or curved in some other way or also multiply curved.
  • the electronic operating part is arranged between the carrier layer and the decorative layer or alternatively on a side of the carrier layer facing away from the decorative layer.
  • the electronic control unit has at least one printed circuit board, at least one lamp arranged on the printed circuit board, which is designed to emit light parallel to the printed circuit board, and at least one light guide element, which is designed to redirect light to the surface of the decorative layer.

If sufficient installation space is available, the at least one light source can also be a top LED, ie an LED that emits light upwards. It is further provided that the light source is designed to provide a mixed light of a mixed color by at least two individual light sources.
  • the illuminant therefore has at least two light sources, which each provide an individual color, so that a mixed color of the individual colors results preferably by controlling or adjusting the intensity of the light from the light sources.
  • one light source can also be provided for each functionality.
  • a first light source could provide search lighting (eg, white light) and a second light source could provide functional lighting (eg, red light).
  • the light sources can be switched alternately, so that in this alternative, the at least one light source alternately provides functional lighting and search lighting. tion can be provided.
  • the light source is preferably designed as an RGB LED or RGBW LED, so that the light source has three or four light sources.
  • the light sources are each designed to emit one of the colors red (R), green (G), blue (B) or white (W) as individual colors.
  • the problem here is that the individual light sources with their different individual colors are often clearly visible to an observer.
  • the light-guiding element determines a light path that extends from the illuminant to the surface and along which the light emitted by the individual light sources mixes completely to form the mixed light.
  • the light path is particularly long enough so that the light from the individual light sources mixes up to the surface to such an extent that the individual light sources are no longer recognizable to the viewer and the viewer only perceives the mixed light that the viewer sees from a single source seems to come.
  • the illuminant can be used to provide search and/or functional lighting as well as design lighting.
  • the design lighting can also represent dynamic lighting, ie a dynamic change (change in intensity and (mixed) color over time) of the lighting.
  • the light path extending from the illuminant through the light-guiding element to the surface, along which light can be emitted from the illuminant through the light-guiding element to the surface is at least 20 mm long .
  • a section of the light path that extends from the lighting means through the light-guiding element is at least 20 mm long. This ensures that the different light colors or individual colors that are provided by the light sources of the illuminant are sufficiently mixed up to the decorative layer to be able to provide a viewer with mixed light in which the individual primary colors are not recognizable.
  • the at least one printed circuit board is flexible and/or has a profile that corresponds to the surface profile.
  • the printed circuit board can be arranged on the carrier element according to a predetermined course and at a uniform distance from the surface, it being possible to ensure at the same time through the flexibility that the distance from the visible surface to a rear side facing away from it remains the same, so that a can be realized in the thickness slim structure of the cover.
  • the printed circuit board can be a deep-milled printed circuit board or a flexible printed circuit board.
  • a printed circuit board can also be formed by a plurality of individual printed circuit boards connected in particular by flexible electrical connectors.
  • a distance between a surface of the at least one printed circuit board pointing towards the decorative layer and the surface of the decorative layer remains the same.
  • the at least one light guide element can be arranged between the printed circuit board and the surface of the decorative layer and determine the distance between the printed circuit board and the surface.
  • the printed circuit board can have a sensor element extending in particular over the entire surface of the printed circuit board on a side facing the decorative layer, ie on the visible side, and/or on a side facing away from the decorative layer, ie on the back, which is designed to touch the surface the decorative layer and/or approximation to capture the surface of the decorative layer.
  • a sensor element for example one that works capacitively, can therefore also provide an operating functionality in that a function of the vehicle is triggered when the sensor detects contact or approach.
  • a sensor element can also be designed as a so-called “touch foil” and can be arranged directly on the printed circuit board or between the printed circuit board and the decorative layer.
  • the control panel can also include (electrical) components through which feedback can be given to an operator.
  • the control panel can have movement actuators for haptic feedback (vibration) or acoustic actuators for acoustic feedback.
  • the at least one light source and the at least one light-guiding element are arranged on a side of the printed circuit board that faces the decorative layer.
