Description

The invention relates to a vehicle window and a vehicle with a vehicle window.

From the prior art are vehicle windows with sensors, for example from the document EP 2 121 308 B1 , known. These sensors can also, as in EP 2 121 308 B1 described, be integrated into the vehicle window (between individual layers of the vehicle window).

In general, the known solutions for vehicle windows, which can be configured, inter alia, with sensors, with regard to their optical properties felt to be relatively susceptible to interference.

In the manufacture of a vehicle window, a bending process is carried out under thermal influence. In this case, the vehicle window can have different temperatures along transparent areas and printed or black-printed area, so that the bending behavior along the vehicle window can vary. As a result, for example, transparent areas and black-printed areas of the vehicle window can have different bending radii.

The consequence of such deviations or variations of the bending radii are considerable distortions along the vehicle window. There are so-called "focal lines" along the boundaries between transparent and black printed areas of the vehicle window.

The focal lines lead to a diffraction of the light, so that an optical distortion takes place. The occurrence of focal lines as an optical property or optical effect can therefore have a considerable influence on e.g. exert the accuracy of the optical sensors. Furthermore, such distortions in the peripheral areas of the vehicle window can also be perceived by a vehicle driver and at least disturb the overall impression.

In this case, black print areas are provided, inter alia, for aesthetic reasons along sensor arrangements on vehicle windows in order to hide, for example, splices for fastening the sensor units.

The invention is therefore an object of the invention to provide a vehicle window, which is an aesthetic. provides a distortion-free appearance, is inexpensive to produce and provides improved optical properties.

The object of the present invention is achieved by a vehicle window according to the independent claim 1. Advantageous embodiments and further developments emerge from the dependent claims and from the description with reference to the figures.

The vehicle window according to the invention, in particular for a motor vehicle, a bus, a train or a ship, is provided with at least a first disc element and a second disc element, which are connected to one another in a planar manner, so that the vehicle window has a first disc surface, a second disc surface, a third disc Disc surface and a fourth disc surface. The second disk surface has a first printing area and the third or fourth disk surface has a second printing area for configuring a viewing area along a vehicle window. The first and second printing areas are each configured with at least a first, second and third zone, wherein at least one of the first and / or second zones is at least partially printed and the third zones are each unprinted, and wherein the second zones each act as a transition area are formed between the first zone and the third zone, so that at least one optical effect of the first pressure range can be compensated, preferably compensated, by an optical effect of the second pressure range

The invention is based on the idea that first and second disk elements of a vehicle window are each designed with printing areas, so that occurring optical effects or optical properties cancel each other or compensate each other.

By the first pressure range and the second pressure range are configured with different adapted or coordinated zones, a compensation of optical effects or properties can be carried out so that, for example, a focal line or an optical diffraction within the vehicle window can be compensated. In particular, mutually corresponding optical effects should be provided so that the mutually corresponding effects in sum preferably cancel each other out.

By optical effects or properties along the vehicle window, in particular in a field of vision of a vehicle driver and / or an optical sensor or a sensor arrangement can be canceled or avoided, are at least a distortion-free appearance, pleasant visibility conditions for a driver and / or improved Accuracy or reproducibility of the results of sensors or sensor arrangements can be achieved.

It is thus provided in particular that a vehicle window with advantageous optical properties can be provided for use with an optical sensor on the basis of the present invention.

Furthermore, it can be provided that a vehicle window with advantageous optical properties can be provided for a vehicle driver on the basis of the present invention.

The vehicle window according to the invention has at least one first disk element and one second disk element, which are connected to each other in a planar manner, so that the vehicle window is configured with a first disk surface, a second disk surface, a third disk surface and a fourth disk surface.

Preferably, the first and second disc element are arranged on each other by lamination and connected to each other. Thus, a laminating layer can be provided between the first and second disk element. This corresponds to a commonly used procedure for providing interconnected disc elements for a vehicle window.

Based on the laminated disk members, a basic structure for a vehicle window optical system is provided.

Based on the connected disc elements a total of four disc surfaces are available. The first disc surface represents the outside of the vehicle window. The fourth disc surface represents the inside of the vehicle window.

The second and third disc surfaces are opposed to each other with a lamination layer interposed therebetween.

The second disk surface has a first printing area and the third or fourth disk surface has a second printing area for forming a viewing area along a vehicle window, e.g. for at least one optical sensor.

By means of the present invention, it is provided to design a vehicle window or a viewing area along a vehicle window with advantageous optical properties. This applies both to a driver of a motor vehicle, a ship or the like, as well as the application of sensors or optical sensors. By way of example, the present invention is to be explained below, in particular with regard to the use of optical sensors, wherein selbige versions are to be used for a driver.

In the context of the present invention, a pressure range can be understood to mean, in particular, a region of a disk surface or a disk element which can be suitably coated, for example partially coated, by means of black printing or screen printing, for example.

Thus, a print area can have both continuously printed areas or zones, partially printed areas and non-printed areas.

The second pressure area may be arranged along the third or fourth sliding surface. Preferably, and set forth below by way of example, the second pressure region is arranged on the fourth disk surface.

In this sense, a third pressure range, e.g. be provided on the third disc surface.

For the purposes of the present invention, the viewing area can be understood as the area of a vehicle window that influences the optical properties or conditions or conditions of a sensor measurement or the field of vision of a vehicle driver.

Depending on the application or individual case, both central areas and peripheral areas of a vehicle window can be assigned to the viewing area. While a sensor is primarily to assign a viewing area in more central portions of a vehicle window, the field of vision of a driver may include the entire area of a vehicle window including the edges.

Thus, the viewing area can be defined as the area in which the sensor or the sensor arrangement can "see" optical effects or optical properties of a vehicle window, that is to say an influencing of the measurement results of the respective sensor.

Thus, for example, the field of vision does not merely refer to a e.g. transparent region of a vehicle window through which electromagnetic radiation can pass in the course of an optical measurement. Rather, the viewing area in the sense of the present invention also describes surrounding or peripheral areas, which in particular can influence the refractive power of the first and / or second disk element along the optical axis of the at least one sensor.

According to the present invention, the first and second pressure regions are each configured with a first, second and third zone, wherein at least one of the first and / or second zones (FIG. 14.1 ; 14.2 ; 15.1 ; 15.2 ) is at least partially printed and the third zones are each not printed, and wherein the second zones are each formed as a transition region between the first zone and the third zones, so that at least one optical effect of the first pressure range can be compensated by an optical effect of the second pressure range is.

The first and second pressure range are subdivided in terms of their design in each of three zones. Within the scope of the present invention, these zones can be regarded as preferably distinguishable surface areas or sections in a viewing area of the optical sensor.

The first zone represents a zone that determines a global, optical behavior of the vehicle window. The first zone preferably has an imprint, in particular a black imprint. Alternatively, the first zone may be at least partially unprinted.

The second zone represents a transition region between the first zone and the third zone. Thus, the second zone may be considered as a printed area, particularly as a partially printed area, to provide a transition between the first and third zones.

Alternatively, the second zone may be integrated into a first zone.

In this sense, the second zone may represent a progressive, gradual, or soft transition or an abrupt, immediate, hard, or infinitesimally short transition between the first and third zones.

The third zone is always configured as a transparent zone of the first and second printing surfaces. By being transparent, the third zone constitutes an area of the first and second printing surfaces through which, for example, an optical sensor or driver can conveniently view through. In this respect, the third zone can be considered as the area that is framed by the first and / or second zone.

The compensation of optical effects or properties on the basis of the first and second pressure range means in particular that, for example, a diffraction by the first pressure range can be canceled by means of an inverted or corresponding diffraction of the second pressure range.

In particular, for the purposes of the present invention, the compensation of an optical effect means the compensation of an optical distortion, so that there is a completely or almost completely distortion-free vehicle window.

Preferably, an inverted optical effect can be achieved by the second pressure range, which corresponds in terms of amount to an optical effect of the first pressure range in this sense.

Thus, for example, the first disc elements with the first printing area form a collecting or concave lens, wherein the second disc element forms a diverging or convex lens with the second printing area, so that a neutral optical system is present in combination of the first and second disc elements.

For the purposes of the present invention, the compensation of at least one optical effect can be understood as the deliberate cancellation of optical effects on the basis of opposing optically inverting components.

The completely composite beam path through the vehicle window preferably exerts no or almost no influence on the continuous optical radiation. In this sense, the beam path provided by means of the vehicle window according to the invention can be regarded as a neutral beam path.

It is possible to transfer an optical radiation undisturbed or almost unimpaired through the vehicle window.

In this context, a compensation by screen printing or black printing can also be understood as meaning an overcompensation or undercompensation of optical effects, so that the entire optical system has no or almost no refractive power, for example.

Such overcompensation not only makes it possible to cancel out the optical effects or distortions, which are justified in particular by screen printing or black printing, but also to compensate for additional optical effects of the vehicle window, as a total optical system.

Alternatively, a screen printing or a black printing in the form of an undercompensation for canceling only a part of the optical effects may be provided, so that the sum of optical effects of the overall system in turn has no or almost no optical distortions.

Thus, by means of demand-based overcompensation by means of the present invention, preferably all or almost all optical effects within an overall optical system of a vehicle driver, a sensor or optical sensor or the like can be canceled.

In general, an optical impairment or distortion of measurement results due to, for example, focal lines or diffraction effects can be avoided on the basis of the present invention.

In addition, other factors may affect the optical characteristics or conditions of a vehicle window. In particular, the thickness of the individual disk elements or the vehicle window as a whole, the color of the disk elements, the laminating layer between the at least two disk elements or coatings on or between the disk elements can exert an influence on the optical conditions in the sense of the present invention.

Thus, it may be provided in the sense of the present invention to design the first and / or second printing region in such a way that the overall optical system of the vehicle windscreen has no or virtually no optical effect, in particular no optical refractive power, and thus a neutral optical system can be provided.

For example, the disc elements may have different or identical thicknesses. In particular, disc thicknesses are provided which correspond to the dimensions commonly used in the motor vehicle sector. Furthermore, the use of thin glass for a disk element or for both disk elements, e.g. with thicknesses of less than or equal to 1.2 mm, preferably less than or equal to 1.0 mm and particularly preferably from 0.6 mm to 1.0 mm, conceivable.

With regard to the color of individual disk elements, provision may be made for at least one of the disk elements to have a coloration in green, blue, white or another coloration customary in the field of motor vehicles.

In addition, coatings along the disc surfaces, especially along the second, third or fourth sliding surface are conceivable, such as e.g. an infrared-reflective coating or a coating for reducing the heat emission ("low-emissivity" coating).

In this case, for example, an infrared-reflective coating can also be provided within a laminating layer between the two disk elements. Thus, the formation of a laminating layer in the form of two polyvinyl butyral layers (PVB layers) or films is conceivable. Between the two PVB layers, an infrared-reflective or infrared-absorbing intermediate layer may be provided, so that a sandwich construction is present.

In addition, the pressure ranges in their concrete embodiment with regard to shape and printing form can be adapted to other factors, such. the cover of splices of a sensor or a sensor unit, the provision of a printed surface as an adhesive surface for other components or the like.

In summary, in the course of the present invention, a targeted adaptation of the first and second pressure surface to the conditions of a vehicle window is provided in order to compensate for optical effects or properties and in particular to be able to provide a distortion-free vehicle window.

According to one embodiment, it is provided that a refractive power as an optical property of the first disk element in the first printing area is determined by a refractive power as an optical property of the second disk element (FIG. 12 ) is compensatable in the second pressure range.

In particular, the occurrence of a focal line at a transition between an at least partially black printed zone and a transparent zone of a printing area can be reduced or avoided. In this sense, an optical diffraction can be counteracted by the second pressure range having an inverted refractive power, which corresponds in magnitude to the refractive power of the first pressure range.

According to a further embodiment, the first zone of the first printing area is printed continuously or with a pattern of individual elements.

In particular, under a continuous pressure is a complete coating of the surface in the course of a printing process, such as e.g. a screen printing process to understand. In this case, the first zone is completely black colored or coated in the case of a black print. This achieves maximum absorption of incident electromagnetic radiation as well as the lack of transparency of the first zone.

A pattern is created by a recurring, relative arrangement of individual elements to each other.

In one embodiment, the second zone of the first printing area is at least partially configured as a pattern of printed individual elements.

The second zone may in this sense have areas that are completely printed or not printed. Furthermore, the second zone of the first pressure region has at least one partial surface which is equipped with a pattern of individual elements.

The configuration of the second zone of the first pressure range can be provided such that the second zone is supplemented by the first zone and / or the third zone. Thus, the second zone may only partially surround the third zone to provide a transition between the first and third zones in this area.

The specific configuration of the first, second and third zones of the first and second pressure ranges is always based on the optical end result to be achieved, which results from a combination of the first and second disk elements.

The formation of the first, second and third zones of the first and second pressure range is in this sense, as needed, variable and tunable to each other.

In a further embodiment, the first zone of the second printing area is continuous, with a pattern of individual elements or not printed.

Thus, the first zone of the second printing area, as well as the first zone of the first printing area, can be configured completely non-transparent or pattern-printed.

In one embodiment, the second zone of the second pressure area is at least partially configured as a pattern of individual elements. In this sense, the second zone along the second pressure region or the second disk element is to be understood as a transition region between the associated first and third zone.

The second zone of the second printing area can be printed in such a way with a pattern of individual elements, so that, for example, an optical diffraction in connection with the first printing area of the first disk element can be canceled.

In this way, an optical effect of the first disk element can be compensated by a corresponding optical effect of the second disk element.

According to a further embodiment, the first zone and / or the second zone of the first pressure region and / or the second pressure region is at least partially identical to the respectively associated third zone.

Any convenient variation of printed and unprinted areas or zones is applicable. In particular, individual zones can also merge into each other and are not strictly geometrically delimited from each other. In this sense, in particular first and second zones can be considered as at least partially integrated or identical.

Thus, for example, the third zone of the second pressure range identical to the associated third zone as not printed and thus made transparent.

Furthermore, for example, the second zone of the first printing area may be partially unprinted, such as the associated first zone.

According to a further embodiment, the pattern of individual elements of the first zone and / or the second zone of the second pressure region may be a gradient pattern.

In particular, a gradient pattern can be understood to mean that the characteristics of the printed pattern change over the printed area. Thus, the size of the individual elements, the distances of the individual elements, the shape of the individual elements, a coloring of the printed individual elements or a comparable characteristic feature along the relevant printing surface can be varied.

In this sense, the pattern of individual elements along the surface of the first and / or second zone of the second pressure range can vary or vary.

Furthermore, such a gradient pattern may generally be provided for any zone of the first and / or second pressure range.

In an embodiment, it is provided that the first and second zones of the first and second pressure regions are formed at least partially in the form of a black print.

In this sense, it is possible to design the first and second zones in such a way individually and adapted with a black print that in particular effects such as a refractive power in the optical system of the vehicle window can be compensated. The vehicle window preferably has no or almost no optical effect, for example in the form of a refractive power.

Furthermore, the black printing can be provided as a diaphragm for the purpose of advantageously distortion-free design of the vehicle window.

According to one embodiment, the first pressure region and the second pressure region can each be configured as a screen printing.

By means of the screen printing method, a cost-effective duplication of the first and second printing area for the mass production of vehicle windows according to the invention is thus possible.

Furthermore, in the course of a screen-printing process it can be provided that functional layers are otherwise applied alongside or instead of a black print along one of the pane surfaces of the vehicle window. Thus, at least one of the disc surfaces may be provided with elements for the realization of e.g. a heating or antenna function or other functionalization are coated.

For example, an infrared-reflective coating or an electrically conductive coating for implementing a disc, camera or sensor heating is conceivable. Also, the design of a coating to reduce the heat radiation, a so-called "low-emissivity" coating, possible, and any other, any functionalizing coating is conceivable. In particular, such functionalizing coatings can be arranged on the third or fourth disk surface, preferably on the third disk surface. A "low-emissivity" coating is preferably arranged on the fourth disk surface.

In one embodiment, for a printed pattern of discrete elements, the discrete elements have the geometric shape of a circle, a rectangle, a square, a rhombus, a hexagon, an octahedron, or the like.

The design with a pattern of individual elements describes in particular the printing with a plurality of preferably arbitrarily or as needed ausgestaltbaren elements.

In a sidelined aspect of the invention, a vehicle is provided, in particular a motor vehicle, preferably a passenger or truck, a bus, a train or a ship, with a vehicle window according to one of the preceding claims.

Consequently, the vehicle window according to the invention can advantageously be used for vehicles. In conjunction with optical sensors improved measurement accuracy can be achieved with the vehicle window according to the invention.

In a further, ancillary aspect, a method for producing a vehicle window or a vehicle according to the invention with a vehicle window is provided, wherein at least one of the second zones of the first and / or second pressure region are formed as a transition region between the first zone and the third zone so that at least one optical effect of the first printing area is compensated by an optical effect of the second printing area.

In the course of the production process of a vehicle window according to the invention, the bending behavior is dependent on the heat absorption of the vehicle window. The heat absorption is adjustable or configurable on the basis of the printing or black printing of local areas of the disk elements of a vehicle window. In particular, for this purpose, the density or intensity of the printing with individual elements, the shape of the individual elements, the configuration can be varied as a completely printed surface or the like, so that there is a specific, individually designed surface section.

Thus, by means of a concrete, individual design of a printed area, the bending behavior of a vehicle window, in particular in individual local areas, can be influenced. Thus, also optical effects or properties of the resulting vehicle window such. Distortions, in particular the refractive power of the vehicle window, based on the configuration of the first and second pressure range substantially configurable.

Furthermore, it is provided in the sense of the method according to the invention that all the above-described embodiments of a vehicle window pane or a vehicle according to the invention can be expediently implemented or provided within the scope of the manufacturing method according to the invention.

Thus, a completely or almost completely distortion-free vehicle window can be provided by means of the method according to the invention.

The invention will be explained below with reference to the attached figures.

According to 1 have the first and second pressure ranges 14 ; 15 both transparent and black-print coated or printed, non-transparent areas or zones. Accordingly, it is provided that the at least one optical sensor substantially along a transparent part of the pressure areas 14 ; 15 is positioned or through transparent portions of the pressure areas 14 ; 15 performs an optical measurement.

The first and second pressure range 14 ; 15 are after 1 configured with two transparent areas for coupling sensors. The transparent areas are cylindrical or square along the pressure areas 14 ; 15 educated.

In particular, the transparent areas or zones are along the first and second pressure areas 14 ; 15 essentially designed in the same form.

The transparent areas along the first print area 14 may have larger dimensions than the transparent areas along the second pressure area 15 , This is based on the outward-directed first pressure range 14 an adequate, transparent region can be provided for a fan-shaped or conically extending beam path, for example of a sensor arrangement, as well as eg a suitable protection against solar radiation.

Furthermore, it is conceivable that the after 1 shown transparent areas are designed as semi-transparent surface areas or the like. In particular, this may be the case when using infrared sensors or other sensors which work with electromagnetic radiation in the invisible wavelength range.

In the 1 illustrated transparent portions of the first and second printing area 14 ; 15 illustrate in this sense, in particular the coupling regions of two sensors along the fourth disc surface 12.4 or along the second disc element 12 ,

In 2 is an overview of a zoning of the first pressure range 14 along the second disc surface 11.2 of the first disc element 11 illustrated.

An adaptation or preferably individual adaptation of the optical properties of the vehicle window 10 is especially along the field of view 16 relevant. So it is envisaged that the pressure ranges 14 ; 15 each are at least partially or completely printed with an individually designed black print.

Deviating from the 3 can the field of view 16 also be defined with another geometric shape, such as circular or hexagonal. The formation of the relevant field of view may depend on the shape of the vehicle window, the type of sensor coupled, the environmental conditions that act on the vehicle window, or the like.

The second zone 14.2 is at a sharp side end and a flat side end of the frusto-conical third zone 14.3 designed as a pattern of individual elements.

The third zone 14.3 may also have an otherwise different form of deviating from a frusto-conical geometry. The frusto-conical geometry of the third zones 14.3 ; 15.3 is in the sense of 3a to 3d as well as the 4a to 4e merely to be understood as an exemplary embodiment.

In 3d is a first zone 14.1 provided as a pattern of printed single elements, the second zone 14.2 as in the first zone 14.1 integrated can be understood. In this sense, the second zone 14.2 completely in the first zone 14.1 integrated provided.

The first and second zones 14.1 ; 14.2 surround the frusto-conical third zone 14.3 Completely.

In the 4a to 4e are different embodiments of the embodiment of the second pressure range 15 along the second disc element 12 shown.

With regard to the embodiments of the first, second and third zones 15.1 ; 15.2 ; 15.3 of the second pressure range 15 the same options are applicable as already above for the first printing area 14 explained.

To 4a is the first zone 15.1 designed as a continuous black print, the third zone 15.3 not printed and thus provided transparent.

The second zone 15.2 can than in the first zone 15.1 be understood integrated.

Generally, the second zones 14.2 ; 15.2 within the meaning of the present invention, if necessary identical to the first zones 14.1 ; 15.1 be designed or integrated into this. In such a case, a transition region forms as a second zone 14.2 ; 15.2 between the first and third zones 14.1 ; 14.3 ; 15.1 ; 15.3 in the sense of the present invention, in particular directly along the border to the transparent, third zone 14.3 ; 15.3 out.

It is an individual and expedient embodiment of the first and second pressure range 14 ; 15 with first, second and third zones 14.1 ; 14.2 ; 14.3 ; 15.1 ; 15.2 ; 15.3 provided a suitable combination of disc elements 11 ; 12 to compensate for optical effects, especially in a field of view 16 an optical sensor.

To 4b the first zone is printed with a pattern of individual elements, wherein the individual elements have a circular shape.

The second zone 15.2 is in the first zone 15.1 shown integrated.

In 4c is the second zone 15.2 also as in the first zone 15.1 integrated provided.

The first zone 15.1 is designed as a pattern of individual elements, wherein the individual elements have a hexagonal shape.

To 4c is the first zone 15.1 provided with a gradient pattern.

The gradient pattern is in the form of varying sizes of the hexagonal individual elements. In particular, the size of the hexagonal discrete elements varies along the course of the flat frusto-conical end of the third zone 15.3 in the direction of the tapered end of the frusto-conical third zone 15.3 ,

Instead of a simple, uniformly designed pattern of individual elements, a gradient pattern can always be provided for the purposes of the present invention, wherein the size of the individual elements, the shape of the pattern, distances of the individual elements from one another or comparable features of the printing can change.

In 4d is the first zone 15.1 of the second pressure range 15 identical to the third 15.3 as not printed or transparent.

The second zone 15.2 framed the third zone 15.3 Completely. The second zone 15.2 is formed with a circumferential gradient pattern of square individual elements.

The gradient pattern is in particular designed such that along the rounded edges of the third zone 15.3 a spread of rows of individual elements takes place. So lies along the rounded corners of the third zone 15.3 a lower density of individual elements within the second zone 15.2 in front.

To 4e is the first zone 15.1 printed or designed with a uniform pattern of circular individual elements.

The second zone 15.2 is along the flat side end of the frusto-conical third zone 15.3 provided as a gradient pattern of individual elements.

The individual elements have substantially a circular geometry, wherein the individual elements overlap in places. A partially serpentine pattern is achieved.

Apart from the blunt or flat side end of the third zone 15.3 is the second zone 15.2 as in the first zone 15.1 integrated or designed as identical to this. This is how the second zone rises 15.2 to 4e only at the blunt end of the third zone 15.3 from.

The third zones 14.3 ; 15.3 are always as a transparent portion of the first and second pressure range 14 ; 15 delimited, so that a vehicle driver, an optical sensor or the like through the transparent third area 15.3 can see through.

In general, by arranging the first and second disc elements 11 ; 12 a combination of specifically designed first and second pressure ranges 14 ; 15 be provided to optical effects or properties of individual disc elements 11 ; 12 to compensate.

In particular, the second zone 14.2 ; 15.2 can act as a transition area between the first and third zones 14.1 ; 14.3 ; 15.1 ; 15.3 be configured as needed.

So can a vehicle window 10 which has advantageous optical properties for use with at least one sensor or sensor arrangement.
