Description

The present invention relates to a visible / interior component for the interior of a vehicle and to a vehicle as such.

In the interior or interior of vehicles and in particular of passenger cars, surface elements in the form of displays for the presentation of information, but also frequently in the form of elements for ambient lighting, are used. However, previous lighting concepts with backlighting cannot be used with many surface materials, especially when daytime visibility is important, as is the case with the display of information.

The invention is therefore based on the object of specifying a visible / interior component for the interior of a vehicle and a vehicle as such, in which, in connection with backlighting for surface elements, a higher degree of flexibility in the choice of material is achieved while at the same time achieving daytime visibility becomes.

The object on which the invention is based is achieved in a visible / interior component according to the invention with the features of claim 1 and in a vehicle in accordance with the invention with the features of claim 9. Advantageous further developments are the subject of the respective dependent claims.

1. (i) mit einem in einem sichtbaren Spektralbereich zumindest teilweise transparenten und eine Oberseite und eine Unterseite aufweisenden Oberflächenelement und
2. (ii) mit einer Beleuchtungseinheit, welche auf einer der Unterseite des Oberflächenelements zugewandten Seite angeordnet oder anordenbar und eingerichtet ist, Licht in dem sichtbaren Spektralbereich des Oberflächenelements mit einer Leuchtdichte in einem Bereich oberhalb von etwa 5000 cd/m² zum steuerbaren Beleuchten und durchleuchten des Oberflächenelements von der Unterseite auszusenden.

According to a first aspect of the present invention, a visible / interior component for the interior of a vehicle is created, which is designed

1. (i) with a surface element which is at least partially transparent in a visible spectral range and has a top side and a bottom side, and
2. (ii) with a lighting unit, which is arranged or can be arranged and set up on a side facing the underside of the surface element, light in the visible spectral range of the surface element with a luminance in a range above about 5000 cd / m ² for controllable illumination and transillumination of the To send out surface element from the underside.

Due to the measures provided according to the invention and the associated increased luminance, the selection of usable materials for the surface element results in greater flexibility, while at the same time daytime visibility can be guaranteed when used with a higher degree of reliability.

With regard to daytime visibility, particularly advantageous conditions arise when, according to a preferred exemplary embodiment of the present invention, the underlying lighting unit has one or more LED matrix elements in the proposed visible / interior component. With such elements, the required high luminance levels can be achieved within the framework of a particularly energy-efficient, compact design.

Additionally or alternatively, the lighting unit can be set up to emit light in the visible spectral range with a luminance in a range up to approximately 10,000 cd / m ² and preferably in a range up to approximately 20,000 cd / m ² , thereby increasing reliability to ensure daytime visibility.

In another advantageous embodiment of the visible / interior component according to the invention, it is additionally or alternatively provided that the lighting unit is set up to emit light in the visible spectral range of the surface element, which is or has white light, corresponds to white light and / or to or has several RGB components individually or in combination with one another.

According to another development of the visible / interior component according to the invention with regard to production and / or assembly, particularly simple geometric relationships arise when the top and bottom of the surface element are opposite one another and / or the surface element is set up in such a way that the top of the Surface element faces an interior of the underlying vehicle and / or is.

The possible uses of the visible / interior component according to the invention should advantageously not only serve to improve and adapt the ambience of the interior of the vehicle. Rather, there are applications that serve the visual representation of information and therefore relate to the classic display sector.

It is particularly advantageous if, according to a further development of the visible / interior component according to the invention, a partitioning unit for controllably partitioning off light emitted by the lighting unit for illuminating the surface element is formed between the surface element and the lighting unit. When using and operating a visible / interior component configured in this way, the light field radiating through the surface element can be used to display information content by appropriate control of the partitioning unit, with many possible applications being conceivable.

These possible applications relate to a typical instrument display, that is to say regarding the status of a device or unit of the underlying vehicle, the time, a temperature or other parameters.

For this purpose, it is particularly advantageous if, in one embodiment of the visible / interior component according to the invention, the partitioning unit is designed as a whole with a plurality of controllable partitioning elements, which are in particular arranged in a matrix-like manner and / or as pixels and are designed to controllably partition off or let through incident light.

The sealing off can be or will be implemented in a binary manner - that is, as either light transmitting or light not transmitting.

Alternatively, it is also conceivable to implement a partition with several and in particular with more than two intermediate levels, for example in a kind of gray scale or in one or with a scale with different brightnesses.

Particularly simple conditions arise with regard to manufacture, production costs and / or manageability and controllability if the partitioning unit alternatively or additionally has one or more LCD matrix elements and in particular is designed as a whole as an LCD display.

The visible / interior component according to the invention can be used in a variety of ways in order to improve the ambience and / or the functionality of the interior of a vehicle on which it is based.

In particular, it can be thought of using the visible / interior component as part of a cladding of the interior of the vehicle and / or as a component of a dashboard, a steering wheel, a speed selector lever, a shift lever, a center console, a door area, a pillar area and / or as an area of a To train roof liner or the like and to use.

Additionally or alternatively, functional elements can also be or will be assigned to the visual / interior component, for example in that a touch-sensitive and / or pressure-sensitive layer or unit is or is formed, in particular in the manner of a switch or pushbutton.

It is advisable to use the lighting to indicate the respective function and / or operation of the switch or button.

On the bottom 12th of the UI element 10 a carrier element closes for mechanical stabilization and / or shaping 20th with its top 21 and the opposite underside 22nd at.

On the bottom 22nd of the carrier element 20th closes with its top 31 a foreclosure unit 30th on, which can also be used as a partition display 30th can be understood and for example also as an LCD unit 35 can be formed.

On the opposite bottom 32 the foreclosure unit 30th a lighting unit closes 40 that is also called an LED unit 45 can be understood with their upside 41 on which a bottom 42 opposite.

The UI element 10 is partially or completely transparent in a certain visual spectral range and can therefore be illuminated in this spectral range, for example by light coming from the underside 12th towards the top 11 penetrates.

To during operation by lighting or irradiation by means of the lighting unit 40 actually from the bottom 12th In order to be able to be x-rayed, the layers or plies in between, namely the partitioning unit, have to be 30th and in particular the support element 20th , at least in the spectral range of the surface element in question or in a sub-region thereof also be partially, completely or essentially completely optically transparent.

In operation of the visible / interior component 1 and in particular the lighting unit 40 can therefore from the lighting unit 40 generated light 43 , 44 generated and towards the bottom 12th of the UI element 10 be sent out. In this light 43 , 44 it can be white light or light equivalent to white light, for example light perceived as white. However, one or more colored types of light are also conceivable, for example in the manner of an RGB mixture.

The partitioning unit which is provided and designed - optionally also optionally - can be used for the purpose of that of the lighting unit 40 emitted light field laterally and / or perpendicular to or to the direction of propagation of the light 43 , 44 spatially structuring and / or modulating in order to generate a spatial and / or temporal structured and / or modulated light pattern, for example to create a corresponding ambience, for example with a texture simulation or the like, and / or to display information, for example in form a pictogram, a lettering and / or a time or the like.

To control the operation of the visible / interior component 1 and in particular the lighting unit 40 and / or the foreclosure unit 30th is a control unit 50 educated. It can be an external control unit 50 or a control unit 50 act as part of the visible / interior component. In connection with the control unit 50 are first and second acquisition / control lines 51 and 52 in operative connection with the partitioning unit 30th and the lighting unit 40 trained to control their operation.

An external recording / control line can also be used 53 be designed in operative connection with an external vehicle control or the like.

For the energy supply and for the actual operation of the partitioning unit 30th and the lighting unit 40 can be a power supply / driver unit 60 via supply lines 61 and 62 in operative connection with the partitioning unit 30th and / or the lighting unit 40 be trained. The power supply / driver unit 60 can be via an additional recording / control line 54 by means of the control unit 50 be designed to be controllable.

In connection with 2 are, as has already been mentioned above, various possibilities for the design and arrangement of a visible / interior component designed according to the invention 1 in one through a body 2 defined and surrounded interior 3 of a vehicle 100 explained. A corresponding visible / interior component designed according to the invention 1 may accordingly, for example, but not exclusively, be used in the context of a dashboard 4th , a steering wheel 5 , a center console 6th , a vehicle seat 7th , a speed selector lever, a gear lever, a door area 8th , a pillar area 9 and the like.

To implement the present invention, in particular that from the development of front headlights in vehicles can be used 1 known principle with a light source 40 and a partition display 30th can be used in a different form.

An embodiment of the system according to the invention for a surface element according to the invention 10 consists for example of three main elements or main layers.

On the one hand, there is a light-emitting unit in the manner of a lighting unit 40 , e.g. in the form of an LED unit 45 formed with one or more LED matrix elements, which, if required, also represent RGB colors individually or in any combination and white light, that is to say can generate and emit them. The layer or location of the lighting unit 40 in this form generates the high luminance levels required for daytime visibility.

There is also a so-called partition display 30th formed, for example in the manner of a liquid crystal or LCD display 35 which the light exit to the underside 12th of the UI element 10 and thus the top 11 controlled as a visible surface in a targeted manner, for example via variable shading patterns, possibly in binary form and / or with a plurality of intermediate levels, intensity levels or gray levels.

In the representation according to 1 act the partitioning elements 33 translucent, i.e. as transparent pixels. That means the foreclosure elements 33 let the light 43 happen so that the carrier 20th and the surface element 10 be screened accordingly.

The partitioning elements act against this 34 translucent, i.e. as non-transparent pixels. That means the foreclosure elements 34 let the light 44 not happen so that the carrier 20th and the surface element 10 through the shares 44 of the total light generated and emitted 33 , 44 not be x-rayed.

Overall, the surface element is 10 as a translucent surface of the interior component 1 formed, for example with or from translucent synthetic leather or other materials.

Optionally, further layers or layers can be used, e.g. the one in 1 portrayed carrier 20th , which is purely optional, for the translucent surface 11 of the UI element 10 and / or a touch-sensitive or pressure-sensitive intermediate layer, through which functions of a button, switch, regulator or slide, especially in cooperation with the control unit 50 can be realized. In this case, the interaction of the lighting unit 40 with the foreclosure unit 30th the respective functionality is indicated by displaying corresponding information.
