Description

Motor vehicle with a display device that has a screen arrangement that can be adjusted into different extended positions, and a display device

DESCRIPTION:

The invention relates to a motor vehicle with a display device which has a screen arrangement which can be adjusted along an adjustment axis into at least two different extended positions.

A display device is understood to mean a device, a device component or a device group which is designed to display image content, in particular digital image content. A screen arrangement is understood to mean a component group which has the display area for outputting the image content and which can be adjusted into the different extended positions. The screen arrangement thus forms an adjustable display or an adjustable projection surface of the display device.

Displays are used in motor vehicles to display information to the driver. Typically, displays in motor vehicles are static, or can be fully retractable and fully extendable. When installed, the display is located with its display surface facing the driver, so that a mounting mechanism is behind it from the occupants' perspective. In this way, communication can take place from the vehicle inward to the occupants.

However, if communication is to take place via a screen to the outside, that is to say in the surroundings of the motor vehicle, a second display is required be implemented, the screen side is aligned to a window pane of the motor vehicle.

DE 10 2019 125 596 B3 describes an OLED display for a vehicle, the OLED display being able to be arranged on a control panel of the vehicle. The OLED display is double-sided and is designed to be bendable along at least one bending edge.

A display device for a motor vehicle is known from DE 10 2019 207 514 A1, which comprises a double-sided display comprising a laminate with a first display layer and a second display layer, between which a magnetic layer is arranged.

EP 2 889 722 A1 describes a flexible display device.

The problem to be solved is the provision of a space-saving screen arrangement with a wide variety of options for displaying display content.

The task is solved by the motor vehicle of claim 1. Advantageous developments are given by the dependent claims.

The invention is based on the idea of providing a display device in a motor vehicle that has a screen arrangement that can be adjusted into at least two different extended positions.

The screen arrangement with the two at least partially flexible display surface elements also includes a linear guide arrangement, ie a mechanism for guiding the two display surface elements on a linear guide plane. The combination of the mechanics for the linear guide and the at least partially flexible display surface elements allows the setting of different extended positions and thus the provision of available display areas of different sizes in two different directions.

The screen arrangement has two display surfaces, the display surface of the first display surface element being oriented in a first direction and the second display surface element being oriented in an opposite direction. In other words, the screen assembly has a double-sided display area.

The two display surface elements can be two separate components, for example two separate screens, or each part of a coherent screen. The two display surface elements are at least partially flexible, ie they are at least partially flexible, preferably at least partially rollable. In other words, each of the display surface elements either has a flexible or rollable portion, or is flexible or rollable over the entire area.

Both display surface elements are arranged on the linear guide arrangement, that is, for example, fastened or mounted. When setting different extension heights of the linear guide arrangement, the two display surface elements are pushed out of an interior paneling element of the motor vehicle, for example a dashboard, a center console or a control panel, due to their arrangement on the linear guide arrangement. When retracting the linear guide arrangement, the two display surface elements, due to their flexibility, can be rolled up in the housing or interior paneling element, for example. The screen arrangement is therefore installed in a very space-saving manner in each of the extended positions and in the rest position. In addition, the display surface elements are stabilized in each of the extended positions by the linear guide arrangement, ie the respective display surface can be clamped in each of the extended positions. As a result, the space-saving design is combined with a very high stability of the display surfaces in each of the extended positions, which always results in very good visibility of the displayed content.

The screen arrangement can preferably be arranged in the motor vehicle in such a way that the display surface of the first display surface element is oriented towards the occupants, i.e. towards the interior, and the display surface of the second display surface element is oriented towards a window pane of the motor vehicle, i.e. towards the outside.

Alternatively, for example, the screen assembly may be arranged between two rear seats, such that one of the display panels faces the right-hand seat of the rear seat and the other display panel faces the left-hand seat of the rear seat. Accordingly, further variants are possible, for example arranging the screen arrangement between the rear seat and the front seats.

With the mechanics, for example, both the display on the inside and the display on the outside can be physically varied. The retraction and extension of the display surface elements, ie the screen arrangement, which can preferably be designed as a display, supports the perceptibility of the display. By moving the screen arrangement, ie the exemplary display, it is perceived more quickly by the user, which is of particular advantage when using rental vehicles, or for example when used by a delivery service for food and drink or parcels. The display device arranged according to the invention also enables a particularly good staging and a high degree of user-friendliness. The display device also offers a user a lot of fun using it and is a special eye-catcher, as well as a unique selling point.

The motor vehicle according to the invention comprises a display device, which is divided into at least two different ones along an adjustment axis Has extended positions adjustable screen assembly. In the respective extended position, the screen arrangement protrudes from an interior paneling element of the motor vehicle. It can optionally be provided that the screen arrangement can also be moved into a rest position in which the screen arrangement is fully retracted into the housing or interior trim element.

In other words, a portion of each display surface of the respective display surface element is visible to a user in each of the at least two extended positions, for example for a user of the motor vehicle and for a person outside the motor vehicle. The screen arrangement therefore has a different extension height in each of the extended positions.

The extended positions of the screen arrangement thus differ, in other words, in a respective extended height of an upper edge of the screen arrangement opposite the lower edge, which can also be, for example, the upper edge of the respective display area. The extension height is understood to be the distance between the top edge and the interior trim element, so that at different extension heights, different portions of a display area are visible to people on the two sides of the screen arrangement. In other words, the extended positions differ in that in each of the extended positions a different proportion of the respective display surface is extended, spread out, unfolded or stretched out. Ideally, the screen arrangement can be continuously adjusted in these extended positions.

Optionally, the display device can have a housing in which the screen arrangement can be stowed at least partially or even completely. Such a housing is regarded as part of the interior trim element of the motor vehicle. In other words, the term "interior trim element" also includes an optional housing of the display device for the screen arrangement. The screen assembly includes a first at least partially flexible or rollable display surface element. The first display surface element therefore has a flexible or rollable portion, or can be flexible or rollable over its entire surface. Optionally, the first display surface element can have a flexible portion and a rigid, unbent portion. The first display surface element is therefore a flat display surface element, ie for example designed at least partially as a tarpaulin, and one of the flat sides, the display side, is designed as a display surface.

The first display surface element can preferably be designed as a display, in particular as an OLED display. Optionally, the display surface element can be designed as a touch-sensitive screen.

The screen arrangement has a second at least partially flexible or rollable display surface element. A display side of the second display surface element is also designed as a display surface. The second display surface element can be configured in the same variants as the first display surface element.

The two display surface elements can either form a single screen element or be separate components. That is, the two display tiles may form an integral screen element, one portion of which is the first display tile and another portion of which is the second display tile.

The screen arrangement has a linear guide arrangement, ie an arrangement, subassembly or component of the screen arrangement which/which comprises a mechanism which enables linear guidance along the adjustment axis on a linear guide plane. The linear guide arrangement can therefore also be understood as a mechanism that can be adjusted within the linear guide plane on which the adjustment axis runs. In other words, the linear guide assembly can be used as an adjustment mechanism Setting the different extension positions of the screen assembly are referred to. The linear guide arrangement can be moved by a motor, for example.

The linear guide arrangement of the motor vehicle according to the invention has at least one slide element that can be displaced along the adjustment axis (and thus on the linear guide plane), i.e. at least one component or at least one component group, which can be displaced along the adjustment axis due to the bearing within the linear guide arrangement. As a result, the extension height of the screen arrangement is adjusted by a distance predetermined by the respective carriage element along the adjustment axis. The adjustment distance can be specified, for example, by the dimensions of the carriage element.

Ideally, the linear guide arrangement can have a plurality of carriage elements which are mounted on one another and can be displaced in relation to one another. The carriage elements can be arranged next to one another, for example, so that, for example, an adjustment of the first carriage element causes an adjustment of the screen arrangement into the first extended position; an adjustment of the second, adjacently arranged carriage element, which can be displaced along the first carriage element, an additional adjustment of the screen arrangement into the second extended position; and so forth. In a development, the carriage elements lying next to one another can, for example, also have different lengths and thus specify different adjustment heights. This development is particularly advantageous for enabling a particularly large number of different extended positions.

In a further variant, the linear guide arrangement can have a plurality of carriage elements which can be arranged next to one another, with the two outer carriage elements forming a pair; the two inner carriage elements another pair; and optionally again two carriage elements flanked by this second pair of carriage elements a third pair of carriage elements, or for example a centrally located carriage element. In this variant, it can be provided that each pair of carriage elements specifies the same distance, i.e. the same extension height, with the respective pair of carriage elements offset by one further inwards allowing an additional adjustment distance, i.e. a respective extension position with a respective higher exit height.

In the screen arrangement of the motor vehicle according to the invention, a rear side of the respective display surface element is arranged flat on the linear guide arrangement, so that the rear side of the respective display surface element lies in or parallel to the linear guide plane. The two display surface elements are on opposite sides of the linear guide arrangement.

In other words, the linear guide arrangement is sandwiched between the two display surface elements. The at least one carriage element, in particular several carriage elements, which can be moved telescopically, determine the extension height of the linear guide arrangement, and thus also the extension height of the two display surface elements, depending on the extension height specified by the adjustment signal. This results in the extended position of the screen arrangement.

As a result, both display surface elements are also adjusted along the adjustment axis when the at least one carriage element is adjusted along the adjustment plane. The arrangement on the linear guide arrangement provides that the respective display surface element can be fastened to the carriage elements with its rear side, for example, can be fastened with an upper edge to a frame of the linear guide arrangement, or is, for example, fixedly or movably mounted on the linear guide arrangement. In other words, the respective display surface element is arranged on the linear guide arrangement in such a way that the movement of the linear guide arrangement during an adjustment process on the first Display surface element is transferred. The back of each

Display surface element is the back of the display side.

In the case of the second display surface element, a rollable end can preferably face the interior lining element, so that the portion that is not extended can be rolled up.

If the two display surface elements form a one-piece screen element, the screen element can enclose the linear guide arrangement, ie the screen element consisting of the two display surface elements can be folded over, for example, a frame of the linear guide arrangement. In this variant, the screen element can either be fastened to the linear guide arrangement or folded over loosely.

The motor vehicle also has a control device which is set up to generate an adjustment signal, the adjustment signal generated specifying the extended position and describing the adjustment of the linear guide arrangement into the specified extended position.

A control device is understood to mean a device, a device component or a device group that is set up to receive and evaluate signals and to generate control signals. The control device can be designed, for example, as a control device, as a control chip or a computer program, or as a computer program in combination with, for example, a control device or a control chip. The control device can preferably be a control device of the motor vehicle.

The control device can have a data processing device or a processor device that is set up to generate the adjustment signal as a function of a current driving mode, for example. Preferably, the control device can also be set up to generate a display or image signal that is generated by one or both Display surface elements output display or image content describes. For this purpose, the processor device can have at least one microprocessor and/or at least one microcontroller and/or at least one FPGA (Field Programmable Gate Array) and/or at least one DSP (Digital Signal Processor). Furthermore, the processor device can have a program code which, when executed by the processor device, is set up to carry out the exemplary adjustment of the screen arrangement as a function of the driving mode. The program code can be stored in a data memory of the processor device.

The control device can preferably include a connection for receiving signals from, for example, a driver assistance system or a sensor device of the motor vehicle, and an output for transmitting the adjustment signal, i.e. for transmitting a control command to, for example, an electric motor for adjusting the linear guide arrangement.

The advantages mentioned above result. A further advantage is that the display area or the display forms a bright area on a rear side, which is better visible from the outside, for example.

The extended position and thus the extended height can depend, for example, on how high a current state of charge of a motor vehicle battery is, in which driving mode a driver of the motor vehicle is currently driving or the motor vehicle is currently parked, or, for example, depending on who is inside and/or outside wants to use the display or is authorized to use it.

The adjustment signal can preferably be an important parameter for the displays on both display surface elements. For example, if the height is adjusted, the drive signals can also be adjusted with the graphical user interface ("GUI") on both display surface elements, so that the GUI, for example on both sides always matches the extended position. In other words, the control device can optionally be set up to generate one or more control signals, each of which describes a display content, depending on the specified extended position, and to transmit the generated control signal or the generated control signals to the display device for outputting the respective display content. The respective display content can optionally depend on the specified extended position.

In a first embodiment of the motor vehicle according to the invention, the first and the second display surface element can be connected to one another and form a single, at least partially flexible screen element, ie for example a single flexible screen. The screen element is wrapped around a front edge of the linear guide arrangement. In other words, the screen element envelops the linear guide arrangement. The screen element made up of the two display surface elements is therefore in one piece. With such a screen arrangement, the double-sided display can be provided with a single flexible screen. The screen element can be rolled up and/or unrolled from a roll at one end, for example. The advantage is that fewer components have to be used as a result.

In an alternative to this, the first and the second display surface element can be two structurally separate display surface elements, wherein each of the two display surface elements can be fastened or mounted on that side of the linear guide arrangement on which the display surface element is arranged flat. Exemplary possibilities for fastening or movably mounting the respective display surface element have already been mentioned above. This advantageously results in the fact that, in contrast to the folded screen element, the two display surface elements can be controlled separately from one another. Another advantage is that the control of the display surface element / the display surface elements is not must be at a top of the screen assembly, and that the screen assembly can be made very thin.

The linear guide arrangement can preferably have a strip element which can be arranged on that carriage element which can be arranged in one of the extended positions in which the screen arrangement protrudes the furthest out of the interior lining element. In other words, the bar element can mark or specify the top edge of the screen arrangement. One or both of the display surface elements can preferably be arranged on the strip element.

A bar element is understood to mean an element designed as a bar, for example a rod or a beam. If the strip element has angled legs, the strip element can also be referred to as a partial frame element or as a frame element.

The strip element again results in a particularly good stabilization of the display surface elements. In particular, the respective display surface element can be stretched particularly well, for example, on a partial frame element or on a frame element.

In a further embodiment of the motor vehicle according to the invention, the display device can have a flat stabilizing element, on the back of which the at least one carriage element rests in the linear guide plane. A stabilizing element is understood to mean a flat element designed as a plate, for example an aluminum plate or a plastic plate. The carriage elements can be mounted on the back of the stabilizing element, for example.

In a first variant, the linear guide arrangement can comprise the planar stabilizing element, on the front side of which the first display planar element can be arranged. In a second variant, the first display surface element can comprise the stabilizing element This means that the first display surface element can be partially applied to the stabilizing element, for example over a large area, or form the stabilizing element. In other words, the first display surface element cannot be designed as a film, for example, but as a stable sheet or stable plate. Alternatively, in a further variant, the second display surface element can correspondingly comprise the stabilizing element.

All variants of the stabilizing element give the screen arrangement an additional stiffening. The stabilizing element can therefore also guide the display surface element.

In a further development of the motor vehicle with the stabilizing element, this can have a flexible, rollable and/or curved portion which faces the interior trim element in the extended positions. The display surface element can be arranged, for example fastened, with its flexible or rollable portion on the flexible and/or curved portion of the stabilizing element. As a result, the display surface element is additionally supported and guided.

In a development with the flexible, rollable and/or curved portion of the stabilizing element, this is particularly flexible and at the same time stable if the flexible and/or curved portion of the stabilizing element has a honeycomb structure or is designed as a honeycomb structure. The honeycomb structure ensures that the display surface element (or the screen arrangement) bends evenly and that the pressure on the display surface element is evenly distributed. This is better for the longevity of the screen assembly. On the other hand, the honeycomb structure in the extended state (display surface element and honeycomb are flat) ensures high stability when the operator applies vertical pressure to the surface, particularly when operated by touch gestures. In a particularly preferred embodiment of the motor vehicle according to the invention, the linear guide arrangement can have at least two carriage elements which are arranged such that they can be adjusted relative to one another along the adjustment axis, preferably with the at least two carriage elements being telescopically adjustable. As a result, the linear guide arrangement can take up particularly little volume in lower extended positions or even when the screen arrangement is being stowed away, that is to say it can be stored in a space-saving manner. Nevertheless, a large number of different extension heights can be set.

In a development, the linear guide arrangement can have at least four carriage elements. A first pair of two of the at least four carriage elements can be arranged adjustably at the same height, and another pair of carriage elements can be flanked by this outer pair of carriage elements. As an alternative to the at least four carriage elements, the linear guide arrangement can have three carriage elements, with an outer pair of carriage elements flanking a central carriage element. Here, too, the linear guide arrangement can be plugged together in a particularly space-saving manner and, if necessary, provide a large number of extended positions with corresponding extended heights. The number of carriage element pairs can vary.

The interior trim element can preferably be located on a window pane of the motor vehicle, so that the display surface element is visible from outside the motor vehicle through the window pane in at least two of the extended positions, preferably in most extended positions or all possible extended positions.

The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus or motorcycle. The above task is also solved by a corresponding display device. This can preferably include the control device described above. Further embodiments of the display device have already been described above.

The invention also includes the combinations of features of the described embodiments. The invention also includes implementations that each have a combination of the features of several of the described embodiments, unless the embodiments were described as mutually exclusive.

The exemplary embodiments explained below are preferred embodiments of the invention. In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention that are to be considered independently of one another and that each also develop the invention independently of one another. Therefore, the disclosure is also intended to encompass combinations of the features of the embodiments other than those illustrated. Furthermore, the described embodiments can also be supplemented by further features of the invention that have already been described.

In the figures, the same reference symbols designate elements with the same function. 1 illustrates the principle of the motor vehicle according to the invention and the display device according to the invention. 1 shows a motor vehicle 10, for example a passenger car. 1 shows a view of the motor vehicle 10 from the outside and through a window pane 12, here the windshield by way of example, into the interior.

Communication between control device 14 and other components can take place via a standard data communication link 18, which can be a wired or wireless data communication link.

The control device 14 can be designed as a control device, for example, or as a control chip, for example. As an option to the representation in FIG. 1 , the control device 14 can also be a component of the display device 20 , for example. The display device 20 comprises the screen arrangement 16. The control device 14 of the example in FIG. 1 can preferably have a data memory 22 and a processor device 24, ie for example one or more microchips or one or more microprocessors.

In the example of FIG. 1 , the screen assembly 16 of the display device 20 is shown in an extended position in which a majority of the screen assembly 16 can be seen. For example, the screen arrangement 16 (highly schematized in FIG. 1) can be a double-sided screen that is partially flexible, preferably rollable. The displacement or movement or adjustment of the screen assembly 16 to the different extended positions can be effected by, for example, pushing or lifting, in which a rollable portion of one or both display surface elements 28, 28' can be rolled up or unfolded. The screen arrangement 16 can be moved at least partially or completely out of and/or into an interior trim element 30, which in the example in FIG. 1 can be a dashboard or a switch panel, for example. In Fig. 1 is by the Window pane 12 to see the display surface 32 of the rear display surface element 28'.

In other words, the height of an upper edge 34 of the screen arrangement 16 can be adjusted. The different extended positions thus differ in the position of the upper edge 34, that is to say in the distance from the upper edge 34, which delimits the portion of the display surface 32 that is visible from the outside. Correspondingly, the extended positions delimit that portion of the display surface 36 of the front display surface element 28 (both of which are not visible in FIG. 1 due to the perspective) due to the corresponding extension height.

The data communication of the control device 14 with a linear guide arrangement 26 and the display device 20 can take place via, for example, wireless or wired data communication connections 18 . The linear guide arrangement 26 can be moved, for example, via an adjustment device 27, which can have components that are designed to adjust the linear guide arrangement 26 and thus the screen arrangement 16, for example a motor, a cable, a locking bar or others, the person skilled in the art mechanisms or mechanisms known in the art for extending, unrolling or unfolding the linear guide. The movement of the linear guide arrangement 26 can be controlled by control signals from the control device 14 .

2 shows another example of the display device 20, wherein the interior trim element 30, for example the control panel, and the display device 20 can be seen in cross section. The motor vehicle 10 of the example in FIG. 2 can include the features that have already been explained for example in FIG. 1 . 2 shows the details of the screen arrangement 16.

The screen arrangement 16 can preferably be a “display-on-demand expandable”, ie a bendable one—for example scrollable - display that can preferably be continuously adjusted in variable Ausfahrhöhen, and preferably situation-specific, so for example depending on a driving mode of motor vehicle 10 or a program that a user of motor vehicle 10 is currently using. The screen arrangement 16 is shown in FIG. 2 in an extended position in which it is partially extended out of the interior trim element 30 . The lower end of the first display surface element 28 that is retracted into the interior lining element 30 is shown as a bent portion 38 .

FIG. 2 shows a cross section through the screen arrangement 16, which is arranged inside the interior trim element 30 so that it can be extended and retracted. The screen assembly 16 can be moved in and out through a shaft 39 . 2 illustrates the sandwich-like structure in which the linear guide arrangement 26 is arranged between the first display surface element 28 and the second display surface element 28'. If the display surface elements 28, 28' form a single, one-piece screen element, this can be folded over at a front edge or face of the screen arrangement 16, ie at its top edge 34. However, the example in FIG. 2 shows two separate display surface elements 28, 28'.

The display surface 36 of the first display surface element 28 can be oriented toward the interior of the motor vehicle, so that the display surface 32 of the second display surface element 28 ′ can be oriented outward. The display surface 32 can therefore be visible from the outside through a window pane 12, and the display surface 36 for the occupants in the interior of the motor vehicle 10. In FIG Display surface element 28 displayed image content emits. Analogously, the arrow 42 illustrates the direction in which the second display surface element 28' radiates. The linear guide arrangement 26 is highly schematized in FIG. 2 and is explained in detail further below, in relation to FIGS. 5 to 10 . 2 focuses on the principle of adjusting the screen arrangement 16 in the various extended positions.

The control device 14 can, for example, generate an adjustment signal as a function of a driving mode (method step S1 , see FIG. 1 ). For example, when the motor vehicle 10 is operated in a fully automatic driving mode, the adjustment signal generated can then describe an extended position in which the screen arrangement 16 is, for example, fully extended. In order to determine the driving mode, the control device 14 can include a connection, for example, via which the control device 14 can receive the corresponding information from a driver assistance system of the motor vehicle. Such a connection can be part of an optional communication module of the control device 14 . Alternatively or additionally, the control device 14 can receive signals from a sensor system of the motor vehicle 10 via such an optional communication module.

To adjust the screen arrangement 16 to an extended position in which a larger proportion of the display surface elements 28, 28' can be seen, i.e. when the screen arrangement 16 is extended S2, the adjustment signal generated can be transmitted, for example, to an electric motor (S3) in order to to control exemplary electric motor. FIG. 1 shows the example that the screen assembly 16 is extended (S2). 2 shows that the screen arrangement 16 can be extended (S2) or partially or completely retracted (S4) into the interior trim element 30 via a corresponding adjustment signal.

In the example of FIG. 2 , the linear guide arrangement 26 can comprise a swivel arm 44 which can be rotated via a joint, a roller or a swivel axis 46 . If the swivel arm 44 is actuated by the control device 14 to extend S2, the swivel arm 44 can be rotated clockwise (S5) in the example in FIG the screen assembly 16 can be lifted out of the shaft 39 and extended (S2).

2 also shows the adjustment axis 47 along which the height of the upper portion of the screen arrangement 16 is shifted.

FIG. 3 and FIG. 4 each show a schematic three-dimensional representation of the exemplary control panel from the perspective of a person who is standing outside the motor vehicle 10 and is looking through the window pane 12, here the windshield in the examples. The steering wheel 48 can be seen in both figures, so the screen arrangement 16 is arranged approximately at the height of the passenger seat. The motor vehicle 10 can preferably correspond to the motor vehicle 10 shown in Fig. 1, with the corresponding display device 20.

From the outside, the person looks at the display surface 32 of the second display surface element 28'. In FIG. 3 the screen arrangement 16 is shown in an extended position, in which only a piece of the screen arrangement 16 has been moved out of the interior lining element 30 . The visible portion of the display area 32 can be, for example, the space for a text line 50 in which, for example, the greeting, for example “Hello”, can be displayed to greet the user of the motor vehicle. The screen arrangement 16 can assume this extended position, for example, if the control device 14 (not shown in FIG. 4) receives a radio signal from a motor vehicle key or a corresponding information signal from a locking system of the motor vehicle 10. The control device 14 then generates in response to this radio signal or this information the adjustment signal (S1), which can specify the extended position shown in FIG.

FIG. 4 shows the screen arrangement 16 in a different extended position, in which a larger portion of the screen arrangement 16 has been moved out of the interior trim element 30 . Motor vehicle 10 can be parked, for example. The generation of the adjustment signal S1 can Example of a state of charge of a traction battery of the motor vehicle 10 depend if the motor vehicle 10 is a hybrid vehicle or an electric vehicle. In other words, the extended position can depend on the state of charge of the traction battery. The motor vehicle 10 of Fig. 4 can be connected to a charging station, for example, and when a fully charged traction battery is reached, the control device 14 can use a corresponding adjustment signal to cause the screen arrangement 16 to be extended even further out of the interior trim element 30 in step S2, for example is fully extended. A battery symbol with the information "100 percent" can be displayed on a display field 52 on the display surface 32 of the display surface element 28' facing the external environment of the motor vehicle 10, optionally also with a corresponding text, such as "I am ready to drive". . 4 also shows the viewing direction 54 of a person who may be outside the motor vehicle.

FIGS. 5 to 8 each show the details of a preferred exemplary embodiment of the linear guide arrangement 26. FIG. 5 shows the screen arrangement 16 from a rear side. The second display surface element 28 ′ is shown transparent in order to reveal the structure of the linear guide arrangement 26 .

The second display surface element 28' can preferably be designed as an OLED display, which can be flexible at least partially, preferably completely, preferably rollable. In the example in FIG. 5, the screen arrangement 16 is shown in an extended position in which a section 56 of the second display surface element 28' has not yet been extended and opened up, and is still rolled up on a carrier element 58 of the linear guide arrangement 26. In the example of FIG. 5 , the linear guide arrangement 26 can have carrier elements 58 on both sides, the extension of which can form an outer carriage element 60 in an angled manner. The respective carrier element 58 can thus be a support structure or a support strut for the linear guide arrangement 26, for example. In the example in FIG. 5 , the two carrier elements 58 are connected to one another by the pivot axis 46 , which can be rotated by the control device 14 . The swivel arm 44 is arranged at a lower end of a stabilizing element 62 and can thus push the stabilizing element 62 out of the interior trim element 30 or pull it back into it.

In the example of FIGS. 5 to 8 , the stabilizing element 62 can be a component of the first display surface element 28 . Alternatively, the stabilizing element 62 can be part of the linear guide arrangement 26 . The stabilizing element 62 has a flexible, ie a bendable, portion 64 and a rigid portion 66, and can preferably be designed as an aluminum plate.

The flexible portion 64 can preferably have a support structure which can be configured as a honeycomb structure 68 . This honeycomb structure 68 is shown in a longitudinal section through the stabilizing element 62 in FIG. 9, and in a three-dimensional view in FIG the flexible portion 64 is vertical, that is, the flexible portion 64 is extended from the interior paneling element 30. The individual honeycombs 70 may preferably be eight to ten millimeters thick and, as previously mentioned, are stiff under load but normal in area.

FIG. 10 additionally shows the bend 72 which the honeycomb structure 68 makes possible. Figure 10 also shows the direction of stress 74. Suitable materials are known to those skilled in the art.

6 shows the screen arrangement 16 in a cross section. In the example of FIG. 6, the two display surface elements 28, 28' are separated from one another. In a variant, however, the two display surface elements 28, 28' form a coherent, one-piece screen element, which can then have been folded around an end face of the linear guide arrangement 26, ie then forms the outer layer of the upper edge 34 of the screen arrangement 16. FIG. 6 also shows a roll 76 on which the second display surface element 28' can be wound and unwound.

Fig. 5 also shows the arrangement of the carriage elements 60, 78, 80 in a rear view. The exemplary linear guide arrangement 26 of Fig. 5 to 8 is an exemplary variant with a strip element 82, which can be designed as a partial frame, and the display surface elements 28 , 28' when extending S2 tightens. The strip element 82 can optionally have a spacing element 84 which spaces the portion of the strip element 82 designed as a partial frame from the central carriage element 80 . Ideally, this spacer element 84 arranged on the partial frame of the strip element 82 can also be designed as a carriage element that can be extended telescopically out of the preceding carriage element 80 and retracted again.

6 shows the screen arrangement 16 in an extended position, in which the carriage elements 78, 80 in the flanking carriage element pair 60 are retracted, so that only the carriage elements 60, 84 specify the extended height.

FIG. 7 shows the screen assembly 16 of FIGS. 5 and 6 in a fully extended deployment position. For reasons of better clarity, not all reference numbers are shown in FIG. 7 .

8 shows the screen arrangement 16 again in a three-dimensional exploded view. Stabilizing member 62 may also be referred to as a beam, specifically a flexible beam that can be flexed or flexed, but is rigid when surface 86 is pressed perpendicularly. From the flexible portion 64 des A portion of the stabilizing element 62 is shown transparently in order to once again illustrate the honeycomb structure 68 under the surface.

The support members 58 are fixedly attached to the exemplary panelboard, which also securely connects the outer pair of carriage members 60 to the panelboard. For the sake of better clarity, not all reference numbers are entered in FIG. 8 either.

The carriage elements 78, 80, 84 are retracted in the manner of drawers, so that the spacer element 84, which is retracted within the carriage element 80, cannot be seen in FIG.

An electric motor for adjusting the pivot arm 44 can optionally be arranged on the roller or pivot axis 46 . Optionally, the control device 14 and/or separate control electronics can also be installed here.

The second display surface element 28' is shown partially rolled up in the manner of a roller blind. The rolling up and unrolling can take place via the roller 76 , which can optionally have a torsion spring 90 . Such a torsion spring allows the second display surface element 28 to be rolled up when the linear guide arrangement 26 is retracted.

11 shows an exemplary embodiment of the motor vehicle 10 in which the screen arrangement 16, which can preferably correspond to one of the exemplary embodiments of the screen arrangement 16 of the previous examples, can display navigation instructions and a route map to a driver 92, for example, via the first display surface element 28 while driving . The display surface 36 of the first display surface element 28 is oriented toward the driver. 11 shows an exemplary embodiment in which the control device 14 (not shown in FIG. 11) can optionally display further information on the opposite display surface element 28', which is projected onto the window pane 12 via a head-up display, for example can. Overall, the exemplary embodiments illustrate how a double-sided flexible display can be provided. The idea here is that a rear side of the display, ie the screen arrangement 16, is also provided with a display surface element 28', preferably a flexible (ie bendable) OLED. This display can be used, for example, for external communication (e.g., detection of motor vehicle 10, greeting, instructions for, for example, delivery of food or parcels, display charge status, warnings such as, for example, "Warning: puddle near the driver's door").

The mechanics can be much like a "simple" extendable flexible display, but is adapted so that it works for both displays, i.e. for both display surface elements 28, 28'.

In other words, the idea envisages a "sandwich" (i.e. a sandwich-like arrangement) of the retractable and extendable display preferably with a flexible OLED mechanism and flexible OLEDs. This gives the ability to provide an inboard and an outboard display that are height adjustable. Another advantage here is that the mechanism can be used to display both the inside and the outside.

The first display surface element 28 can preferably lie on an aluminum plate as a stabilizing element 62, that is to say it can be arranged, with this example aluminum plate being able to be, for example, five to six elements that can be displaced in relation to one another.

The display surface elements 28, 28 'can at the top

Linear guide assembly 26 may be positioned, for example fixed, or an integral screen element may overlay linear guide assembly 26 like an inverted U. The advantages already mentioned above result. The display, ie the screen arrangement 16, can be moved in and out. The display inwards and outwards can be adjusted in height.
