Abstract

The subject matter relates to a device for arrangement on a motor vehicle, comprising: at least one display; a front cover of the display; and a back cover of the display, wherein the front and back covers completely enclose the display.

Description

Field of invention

The subject matter relates to a display device, which can be arranged in particular on a motor vehicle, with the features according to the preamble of claim 1.

Background of the invention

Information that is visible to third parties on motor vehicles is generally unchangeable after being attached to the motor vehicle or can only be changed with considerable effort. In the event that, for example, advertising information on a motor vehicle is to be arranged so that it is visible to third parties from the outside, this is usually done by sticking the motor vehicle with information to be displayed previously transferred onto a film. Should z. If, for example, further or different advertising information is to be displayed on the motor vehicle, the previous advertising information must first be removed from the motor vehicle, so that the new advertising information can then be attached according to the procedure described above.

Displays that are known from the prior art are not suitable for use on motor vehicles because, due to legal provisions, e.g. B. when changing information to be displayed by means of the display and the associated outgoing active lighting, these are not permitted for use in road traffic.

General description of some exemplary embodiments of the invention

For example, in order to enable the display and modification of information to be displayed, such as advertising information, in a user-friendly manner, it would be desirable to overcome the disadvantages known from the prior art and to provide a way to display variable information in a visible manner on a motor vehicle.

Against the background of the state of the art presented, the object of the object is to enable the presentation and modification of information to be presented, such as advertising information, in a user-friendly manner such that the information to be presented is visible from the outside on a motor vehicle.

This object is objectively achieved by a device for arrangement on a motor vehicle, the device comprising: at least one display; a front cover of the display; and a rear cover of the display, the front and rear covers completely enclosing the display; wherein the display is a non-light emitting display (e.g. an e-paper display, or a non-luminous display, or a reflective TFT (thin-film transistor) display); an intermediate space is formed between the rear cover and the front cover, in which space can be arranged for regulating the temperature of the display; and the device further comprises one or more holding devices, by means of which the device can be arranged on the motor vehicle, wherein a respective holding device of the one or more holding devices is designed in such a way that the device is damped against impacts and other operating forces when it is arranged on the motor vehicle .

In the context of the present subject matter, the term “non-light-emitting display”, including as a non-self-illuminating display, is understood to mean a display that does not include an active light source that emits light. Such a non-light-emitting display is, for example, an e-paper display or a reflective display (also referred to as a reflective TFT display). In contrast to this, the term “non-light-emitting display in the sense of the present subject matter in particular not conventionally known LCD (Liquid Crystal Display) z. B. with LED () background lighting, or plasma displays, which, in contrast to a non-light-emitting display, comprise an active light source that emits light, i.e. emitted.

It has been recognized that representational displays initially meet the requirement that information reproduced by the representational display are not active light sources, since representational displays, in contrast to conventional LED displays or the like, for example, have no active background lighting. A physical display therefore does not emit any light. Thus, representational displays can in principle be used in road traffic, in particular without danger in the form of distraction and / or glare from other road users due to the representational display.

The display of the device is therefore z. B. an e-paper display. Such e-paper displays are also referred to as electronic paper, e-paper displays, and e-paper or e-paper display devices. Such a physical display reflects light like normal paper. In contrast to plasma, LCD or LED displays, such a physical display is a passive, non-self-illuminating display. Such a physical display consequently does not emit any light. This makes an objective display suitable for use in road traffic (especially in accordance with the German road traffic regulations) by placing it on a motor vehicle. Accordingly, the use of an objective display in road traffic does not represent a source of light that can sometimes be a nuisance.

In order to be able to implement operating conditions for the display in question, the display is enclosed by a front cover and a rear cover. The display in question is arranged within a space formed between the front cover and the rear cover of the device. The intermediate space formed can be subdivided into one or more dry areas, which for example can be hermetically sealed and / or which are subject to moisture regulation, as well as one or more wet areas into which moisture is allowed to penetrate. The one or more humid areas of the device can be required, for example, for temperature regulation, for example in order to pass air through the one or more humid areas of the device for cooling or heating the display in question.

The rear cover has, for example, at least one bulge in which means for regulating the temperature of the display can be arranged. Furthermore, the device comprises one or more holding devices, by means of which the device can be arranged on the motor vehicle, a respective holding device of the one or more holding devices being designed in such a way that the device is dampened against impacts when it is arranged on the motor vehicle.

A motor vehicle - also referred to as a vehicle - in the context of the present subject matter is understood to mean in particular a vehicle that can be moved by means of its own drive. Such a motor vehicle is, for example, a moped, scooter, motorcycle, passenger car, van, truck, e-scooter, duck train, boat, drone, helicopter, airplane or the like, to name just a few non-limiting examples. The motor vehicle includes, for example, one or more drives. Such a drive is, for example, an internal combustion engine and / or an electric motor. It goes without saying that a motor vehicle in the sense of the present subject matter is not limited to a vehicle for propulsion on land, but can be designed for propulsion on water and / or in the air. In the event that it is a motor vehicle for propulsion on land, it can be provided, for example, with two, three, four or more wheels or with other propulsion means (e.g. chains). Furthermore, the term motor vehicle or vehicle in the sense of the present subject matter also includes vehicles that are mobile in road traffic and that do not have their own drive. These are, for example, trailers that can be moved by a powered vehicle. For example, trailers can have a loading area for the transport of goods.

The one or more holding devices are designed in such a way that the one or more holding devices, when the device is arranged on the motor vehicle, are connected both to the device in question or to a part thereof and to the motor vehicle or vehicle or to a part thereof. The one or more holding devices can, for example, be detachably connected to the motor vehicle, so that the device is held on the motor vehicle. When arranged on the motor vehicle, the device is held in such a way that it cannot become detached from the motor vehicle during operation of the motor vehicle.

The arrangement of the display in question between the front and back cover provides protection against moisture for the display in question, so that environmental influences, such as water (e.g. liquid, solid and / or water), sometimes acting on the device during operation of the motor vehicle gaseous), cannot damage the display in question.

The means for temperature regulation also ensure that environmental influences acting on the device during operation of the motor vehicle, such as high or low temperatures, cannot lead to an interruption in the operation of the display in question or even damage to the display in question as a result.

The one or more holding devices realize a certain impact resistance of the device and in particular of the physical display comprised by the device, so that shocks which are sometimes not fully cushioned by the vehicle (or its chassis) during operation of the vehicle are applied to the device can (such as caused by road damage or the like), be reduced or eliminated in their intensity. The one or more holding devices enable shock absorption in the direction of at least two degrees of freedom, for example.

Due to the moisture protection, the temperature regulation and the shock resistance of the device, the device can be used to reproduce (optical) information by means of the objective display, in particular during the Operation of the motor vehicle or vehicle allows. It is understood that the device or the operation of the device also in the non-active operation of the motor vehicle, for. B. when the motor vehicle or vehicle is parked and / or not moving, is possible by means of the device in question.

An exemplary embodiment according to all aspects of the present invention provides that the means for temperature regulation form an air channel (e.g. chimney shaft with a corresponding chimney effect, i.e. chimney shaft-like cavity) through which tempered air can flow.

The air duct for temperature regulation is provided vertically, for example, so that a chimney effect for temperature regulation can be achieved. The air duct can alternatively or additionally be provided at least partially horizontally. For example, an air duct is routed in a serpentine manner within the rear cover (or the wet area) so that air flowing in can enter a lower inlet opening, for example. The inflowing air can, for example, at least partially flow through the extending air duct by means of a chimney effect through a serpentine to an upper outlet opening of the device.

The means for temperature regulation can include, for example, one or more heat sinks, in particular in order to operate the display in question within a permissible temperature range when the outside temperature is high.

An exemplary embodiment according to all aspects of the present invention provides that the means for temperature regulation furthermore comprise a fan, by means of which air can be introduced into the device from outside the device.

The means for temperature regulation include, for example, one or more fans and / or fans. In particular, the means for temperature regulation comprise one or more radial fans. Alternatively or additionally, the means for temperature regulation comprise one or more axial fans. Such a radial fan sucks in air, for example, and blows it, deflected by 90 ° by rotating the radial fan, for example into an air duct comprised by the means for temperature regulation. In contrast to an axial fan, the use of a radial fan has the advantage that one or more vibrations that are caused by such a radial fan during operation are reduced compared to an axial fan. This ensures, for example, safe operation even with higher counter pressures. Furthermore, the use of one or more axial fans compared to one or more radial fans, for example in the case of counterpressure in the air duct, could lead to a higher loss of power. The one or more fans are arranged in particular on the air inlet opening, so that they suck in air from outside the device and blow it into the interior of the device. It goes without saying that alternatively or additionally one or more fans (in particular according to the type set out above) can be arranged at the air outlet opening, the fans then sucking in air from within the device and conveying it to the outside.

An embodiment according to all aspects of the present invention provides that the means for temperature regulation comprise one or more cooling ribs, so that elements of the device which are in contact with the cooling ribs can be temperature-regulated; and / or comprises one or more heating elements, so that elements of the device which are in contact with the heating elements can at least partially be temperature-regulated.

The cooling fins are arranged, for example, within the rear cover of the device. The cooling fins are each supported, for example, by one or more metal sheets or baffles for guiding air. The cooling fins or the cooling fins held by the guide plates are arranged, for example, within the humid area of the device. The cooling fins are, for example, in contact with the display in question, e.g. B. via a connection that is implemented via a carrier of the display in question.

The one or more heating elements have high thermal conductivity, for example. The one or more heating elements are or include, for example, one or more Peltier elements. The one or more heating elements are designed to give off heat to the elements with which the one or more heating elements are in contact. It goes without saying that in the case of one Peltier element or several Peltier elements, heat can be absorbed accordingly.

The one or more heating elements can form a heater, for example. The one or more heating elements can, for example, form a layer of the device.

Both the one or more heating elements and the one or more cooling fins can be designed in such a way that they enable a planar introduction of heat and / or cold, in particular a heat and / or cold introduction into the elements in contact with them.

An exemplary embodiment according to all aspects of the present invention provides that the rear cover has an air inlet opening and an air outlet opening, wherein air can be sucked into the air inlet opening by means of the fan and can be discharged via the air outlet opening.

By means of the fan, air can be sucked into the air inlet opening and thus into the humid area of the device. The rear cover of the device also has an air outlet opening through which air can be released from the humid area of the device to the external environment of the device. In particular, this enables a (e.g. constant) exchange of air from air located within the humid area of the device. Such an exchange of air enables, in particular, temperature regulation by, for example, removing warm air from the humid area of the device and bringing cooler air into the humid area of the device to absorb heat given off by the present display.

An exemplary embodiment according to all aspects of the present invention provides that the means for temperature regulation are arranged on a carrier, wherein the carrier can be arranged on the rear cover in such a way that the means for temperature regulation are arranged within a recess of the rear cover.

The cooling fins form, for example, a cooler plate (also referred to as a cooling body), which can dissipate heat given off from the display to the cooler plate by air flowing through the humid area of the device.

The display in question is arranged on the opposite side of the carrier so that it can be temperature-regulated, for example. The display in question is held on the carrier, for example by means of a display frame. For example, the display frame completely surrounds the display in question. The display frame also serves, for example, as a centering aid when mounting the display on the carrier. The display is, for example (e.g., over the entire surface) glued to the carrier (e.g. aluminum plate), e.g. with glue or foil). Furthermore, the display in question and the display frame are arranged lying on the same plane, for example.

The transparent element is spaced from the display, for example. This ensures, for example, that forces and / or impacts acting on the transparent element from the outside are not transmitted to the display.

An exemplary embodiment according to all aspects of the present invention provides that one or more electronic components for controlling the display are included in the device, the one or more electronic components being hermetically sealed.

The one or more electronic components can include, for example, one or more controllers for controlling the display. The one or more controllers can be designed as so-called embedded controllers, for example.

The device comprises (or has), for example, a power supply for feeding the display in question with electrical energy. The power supply can for example be provided by the motor vehicle. Additionally or alternatively, the power supply can comprise an accumulator (e.g. a battery) or be a corresponding accumulator. The power supply includes, for example, an embedded controller, or the embedded controller includes the power supply. The power supply can be implemented, for example, by one or more solar cells. The one or more solar cells are included in the device, for example. Alternatively or additionally, a photovoltaic system can be included in the motor vehicle or vehicle, for example, and correspondingly connected to the device for supplying the device with electrical energy (operationally). Alternatively or in addition, the display can have photovoltaic properties, so that, for example, incoming light on the display is converted into electrical energy according to the principle of a solar cell. The generated electrical energy can be stored in an accumulator, for example. In this way, the device can, for example, be operated independently (i.e. independently of an externally added electrical energy).

The one or more electronic components can include, for example, an automatic switch-off of the display in question, so that, for example, in the event that the display in question is in non-permissible ambient conditions (e.g. temperature outside an allowable temperature range for the display in question, and / or air humidity is operated outside a permissible humidity range for the display in question).

A permissible temperature range for the present display is, for example, between the limits listed below: minus 20, minus 15, minus 10, minus 5, 0, plus 5, plus 10, plus 15, plus 20, plus 25, plus 30, plus 35, plus 40, plus 45, plus 50, plus 55, plus 60 degrees Celsius in the immediate vicinity of the device.

A permissible humidity range for the present display is to be considered, for example, between the limits listed below: 0%, 5%, 10%, 15%, 20%, 25%; 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100% relative humidity or humidity in the immediate vicinity of the device.

A prevailing temperature and / or air humidity on the outwardly facing surface of the device in the sense of the present subject matter, for example on the outside of the front cover of the device, is understood as the immediate environment of the device. It goes without saying that this also includes the outer surface of the rear cover of the device, which can sometimes be located in the interior or inner region of the motor vehicle when the device is in the state of the device arranged on the motor vehicle. For the determination, for example, corresponding sensors can be used by the device and optionally encompassed by the device or can be connected to it.

Such an airtight closure of the one or more electronic components enables in particular a moisture protection of the one or more electronic components.

In particular, the device has a dry area and a wet area inside. The representational display is arranged, for example, within the dry area of the device. The dry area is, for example, completely protected from external moisture. Furthermore, the one or more electronic components can be arranged in the drying area of the device. In particular, the means for regulating the temperature of the device are arranged in the humid area of the device. The humid area of the device is formed, for example, by an air duct through which air can flow to regulate the temperature of the display in question. The moist area can be located essentially within a bulge or depression in the rear cover of the display in question.

An exemplary embodiment according to all aspects of the present invention provides that the display is also sealed airtight.

Such an airtight closure of the objective display enables in particular a moisture protection of the objective display. In particular, through the use of the device, and thus also of the display in question in a motor vehicle, the display in question can be exposed to the most varied of environmental influences, such as temperature and / or humidity conditions. In the conventional use of an objective display, particularly in the home, this is not the case, since such use in the home in the interior always guarantees at least dry ambient conditions.

The drying area of the device is sealed off airtight, for example. For example, the device could be manufactured under a protective atmosphere in order to enable an airtight seal of the dry area of the device.

An exemplary embodiment according to all aspects of the present invention provides that the display is also at least partially sealed airtight.

The display is, for example, at least partially hermetically sealed in the event that a drying area can be opened and / or closed for introducing and / or extracting moisture into the drying area of the device. For example, one or more closable openings can exist between the dry area and the wet area, so that, for example, moisture regulation is made possible. The humidity regulation enables, for example, a setting of setpoint values of a humidity that is required, for example, to operate the display in question or the one or more electronic components thereof, to name just one non-limiting example.

An exemplary embodiment according to all aspects of the present invention provides that the one or more holding devices are designed as spring holders, whereby impacts acting on the device can be cushioned by elastic deformation of the one or more holding devices.

The one or more holding devices each have, for example, at least partially reduced rigidity. Such a reduced rigidity can be directional, for example, by means of elastically deformable parts of the respective holding device of the one or more holding devices. In this way, for example, shock absorption of the device can be made possible in a defined (e.g. of two possible) degrees of freedom. Furthermore, it is possible in this way to bridge manufacturing tolerances that sometimes occur during the manufacture of the device.

The one or more holding devices are made, for example, of a metal, in particular stainless steel, fiber composite materials, elastomers, or the like, to name just a few non-limiting examples.

The shock resistance of the device enables in particular the use of the device on a motor vehicle.

An exemplary embodiment according to all aspects of the present invention provides that the front cover - when the device is arranged on the motor vehicle - has no externally accessible fastening means.

In particular, when it is arranged on the motor vehicle, the device has no fastening means (such as screw connections or the like) on the front side that are accessible from the outside by unauthorized third parties. This primarily serves to prevent vandalism and / or theft.

An exemplary embodiment according to all aspects of the present invention provides that the display in question is held on the carrier by a display frame which holds the display in question within the front cover surrounding the display and the rear cover. For example, the support of the display has one or more stud bolts. For example, the display is arranged on the carrier in such a way that it is spaced from the rear cover and / or front cover.

The display is, for example, at a distance from the recess formed by the rear cover, so that the means for temperature regulation can be arranged within the recess of the rear cover.

The carrier is embedded in plastic, for example, so that there is no metallic contact between the carrier and its embedding in the front or rear cover of the display in question.

A welt seals, for example, one or more edges of the device, e.g. B. against environmental influences. Such a welt enables, for example, the display to be sealed against material expansion, which can be caused, for example, by thermal expansion of the front and / or rear cover of the present display, and / or one or more compensations for material expansion. Such a welt allows, for example to avert undesired (tension) forces, a relative movement of the respective components of the device to one another. Furthermore, such a welt enables, for example, a more extensive shock absorption with respect to impacts acting on the display or the device, in particular in addition to shock absorption by the one or more holding devices of the device. Such a welt, which surrounds the carrier of the display in question, also enables, for example, protection of one or more contacts (e.g. control contacts of the display in question) against damage that can be caused, for example, by moisture (e.g. corrosion of the contacts of the representational displays, to name just one non-limiting example).

The carrier consists of or comprises, for example, high-strength aluminum. The representational display is for example (z. B. full surface) connected to the carrier, z. B. glued. In the event that the display in question is glued to the carrier, a thermally conductive adhesive can be used, for example. This enables heat conduction, for example to be able to dissipate heat generated and / or introduced during the operation of the display in question via the carrier.

An exemplary embodiment according to all aspects of the present invention provides that the front cover is at least partially transparent.

The front cover can, for example, have or comprise a transparent element, or alternatively consist entirely of a transparent material. The transparent element has a transparency greater than 0, for example. The transparent element can have a maximum transparency of 100. Such a transparent material is, for example, a polycarbonate, ESG (toughened safety glass), or a VSG (laminated safety glass), or at least partially comprises a polycarbonate, ESG, or VSG. For example, the front cover or the transparent element of the device consists of or the front cover or the transparent element of the device comprises at least partially an acrylic glass, so that the physical display arranged directly behind the transparent area of the front cover is visible through the front cover, and furthermore in particular is protected against damage caused by external influences from outside the device.

An exemplary embodiment according to all aspects of the present invention provides that a medium is arranged between the transparent element and the display. The medium is for example air, a gas, and / or a liquid or solid medium. The medium is, for example, an adhesive. In the event that the medium is an adhesive, what is known as bonding takes place between the transparent element and the display. Such a bonding is a connection technique that produces a (e.g. direct connection) between the transparent element (e.g. glass) and the display.

An exemplary embodiment according to all aspects of the present invention provides that a light guide is arranged between the transparent element and the display. Such a light guide comprises or consists for example of a plastic or the like. Such a light guide comprises, for example, at least partially one or more illuminants. Such a light guide is arranged, for example, in an intermediate space which is formed between the transparent element and the display. For example, the light guide does not cover the display. Such a light guide enables z. B. illuminating the non-reflective display, for example in the dark, so that information reproduced by the display also z. B. are visible to outsiders at night, e.g. B. when a vehicle or motor vehicle on which the device in question is arranged is parked in the dark, to name just one non-limiting example.

The device is for example such on a motor vehicle, for. B. a side wall of the motor vehicle, arranged that, when installed, the front cover is flush with the side wall, rear wall, roof, or a combination thereof, to name just a few non-limiting examples, of the motor vehicle or the vehicle. A suitable side wall, rear wall, roof, or a combination thereof, as stated above, of the motor vehicle or vehicle can, for example, at least partially have an essentially flat area, so that the device can be arranged in this area. The device can, for example, be arranged on an outer wall of a motor vehicle or vehicle by means of a holder (e.g. quick-release holder, magnetic holder, spring and / or pin holder, snap lock, or a combination thereof, to name just a few non-limiting examples) . It goes without saying that in this case the device does not have to end flush with the surface of the outer wall, for example.

An exemplary embodiment according to all aspects of the present invention provides that a respective holding device comprises at least a first and a second elastically deformable element, as well as a main element connected to the first and the second element, the first and the second element being connected to the Main element of the respective holding device are connected so that the first and the second elastically deformable element are elastically movable in the direction of two degrees of freedom relative to the main element.

For example, the first element can be elastically deformable in the direction of a first of the two degrees of freedom. Furthermore, for example, the second element can be elastically deformable in the direction of a second of the two degrees of freedom.

The main element, as well as the first and the second elastically deformable element, are, for example, formed in one piece or in one piece. Alternatively, the first and the second elastically deformable element can also be connected to the main element of a respective holding device of the one or more holding devices via a movable connection, such as a hinge (e.g. spring-loaded hinge or the like). The main element is, for example, firmly connected to the device. The first and the second elastically deformable element, however, are firmly connected to the motor vehicle, for example. If a force, z. B. caused by a shock or the like, transmitted to the motor vehicle, a force is applied to a respective holding device of the one or more holding devices of the device. Due to the elastic deformability of the first and the second element of a respective holding device, the one or more holding devices of the device moves (z. B. deformed) the first and / or second element relative to the main element of the corresponding holding device, so that, for. B. the force of the impact is not fully transferred in its intensity to the device. The elastic deformability is therefore suitable for damping such impacts.

The object according to the invention is also achieved by using the device in question according to all aspects of the present invention, as disclosed above, on a motor vehicle. The device can be used, for example, to reproduce information, in particular in such a way that the reproduced information is visible from the outside when the motor vehicle is viewed.

The object according to the invention is also achieved by a motor vehicle comprising a physical device according to all aspects of the present invention, as disclosed above.

Via the air outlet opening 6th can for example air from this space between the device 1 be left out.

The back cover 3 is in the present case designed in two parts, the rear cover being divided into an upper and a lower housing part of the rear cover 3 is divided.

In 2 FIG. 13 is an exploded perspective view of the exemplary embodiment of a subject device in accordance with all aspects of the present invention of FIG 1a shown.

The (e.g. e-paper) display 7th is from the front cover 2 including the transparent element 4th (e.g. lying directly on the e-paper display). The e-paper display 7th is flush with a display frame 8a outlined. Both the e-paper display 7th as well as the display frame 8a are on a display support 8b arranged, the e-paper display 7th and the display frame 8a firmly to the display support 8b can be connected. The display carrier 8b is designed so that it is in the back cover 3 can be held. The back cover 3 forms a depression or bulge, so that in this Recess in the assembled state of the device 1 those from the front cover 2 and the back cover 3 completely enclosed components (e.g. e-paper display 7th , Display carrier 8b , Means for temperature regulation 9 ) of the device 1 can be arranged.

The area between the front cover 2 and the display carrier 8b can form a dry area. The area between the display support 8b and the back cover 3 can form a damp area.
