Description

The invention relates to a display device for an interior of a motor vehicle having the features of the preamble of patent claim 1.

Such a display device is known from KR 10 2019 0140 806 A known. Specifically, a display device in the roof lining of an autonomous motor vehicle is described. The display device has a display unit with two screens and also includes a frame-like position adjustment unit, via which the position of the screens can be adjusted. The position adjustment unit has a frame-like guide body with lateral guide rails in which guide rods of the screens are guided. Via a drive motor, the screens can be adjusted from a non-use position resting on the roof lining of the motor vehicle to a use position in which the screens are lowered in a V-shape towards the interior.

In the DE 10 2015 005 365 A1 A display device on the instrument panel of a motor vehicle is described, comprising a flexible display unit and an adjustment device that can be covered by a hinged hood. The adjustment device can move the display unit from a stowed position to a use position and vice versa. The display unit is bent in the process and forms an instrument cluster for the motor vehicle. The display unit is adjusted from a stowed position to a use position whenever the motor vehicle's ignition is activated. When the ignition is deactivated, the display unit is again adjusted to the stowed position.

Another display device is from the US2018/0027689 A1 Specifically, this document discloses a display device comprising a plurality of screens mounted on a roof lining. The screens can be arranged in a longitudinally displaceable manner via a quick-connect system in a rail aligned in the longitudinal direction of the motor vehicle. Additionally, the quick-connect system is designed such that each screen can rotate 360 degrees around a vertical axis and 180 degrees around a horizontal axis.

Based on this prior art, the present invention is based on the object of providing an easily mountable display device for an interior of a motor vehicle, in which on the one hand the space requirement in its position of use can be kept low and on the other hand an attractive appearance can be created in the non-use position.

This object is achieved by a display device having the features of patent claim 1. Advantageous embodiments or further developments of the invention can be found in the dependent claims.

Further objects of the present invention are to provide a motor vehicle with increased comfort for passengers and to propose a suitable method for operating the display device in a motor vehicle.

The above objects are achieved by a motor vehicle having the features of patent claim 5 and by a method having the features of patent claim 7.

Advantageous embodiments or further developments of the invention can also be found in the respective dependent claims.

The invention initially relates to a display device for the interior of a motor vehicle. The display device comprises at least one movable screen that can be moved into at least two different positions.

It is further proposed that the display device comprise two screens, each of which can be positively and automatically moved into a predetermined retracted position or a predetermined extended position. In their extended position, the screens form a V-shaped arrangement with one another. In their retracted position, the screens form a common plane with one another.

Such a display device can significantly increase passenger comfort in the vehicle interior. In particular, the V-shaped arrangement of the screens ensures good visibility of one screen at a time for all passengers sitting opposite each other in a vehicle, while saving space.

Due to the formation of a common plane when the screens are retracted, the prerequisite is created that the screens do not get in the way in any way when not in use.

According to a first development of the invention, the screens have mutually facing ends and mutually remote ends. The mutually facing ends form a joint The opposite ends of the screens can be moved toward or away from each other via a positive guide.

The ends of the screens are to be understood as the long or short sides of the screens visible in a plan view of the screens or the long or short sides of the housings that may enclose the display surfaces of the screens.

This further development provides an easily implemented mechanism with which the screens can be brought into the predetermined use or retracted position.

In order to minimize the space required by the display device in the retracted position, another development proposes that the common plane of the screens formed in the retracted position is aligned flush with a surface surrounding the screens.

To minimize the space requirement when the screens are extended and to create an attractive appearance when retracted, one implementation of the inventive concept proposes that the forced guide be arranged in a recess, which is concealed by the screens when retracted. The recess can, for example, be trough-shaped.

In order to ensure automatic movement of the screens in a simple and cost-effective manner, the screens can be moved from their retracted position to their extended position and vice versa by an electric motor.

A further feature of the invention is to design the display device as a component of a built-in module. This allows for particularly easy installation of the display device in the interior of the motor vehicle.

As already mentioned, the invention also aims to protect a motor vehicle. Such a motor vehicle is characterized by at least one display device arranged in an interior of the motor vehicle.

It is considered very advantageous if the display device is arranged in a roof lining and/or in a side panel of the motor vehicle.

The arrangement in a roof lining allows for particularly good and central visibility of the display for passengers sitting opposite each other in the interior of the vehicle, with legroom not being restricted in any way by the display. However, arranging the display in a side panel (e.g., door panel or wall panel) can also be useful, for example, if the display is designed with a touch-sensitive surface (e.g., a touchscreen) and easy accessibility to the screens is desirable for passengers.

Finally, a suitable method for operating a display device according to the invention in a motor vehicle is also proposed. Such a method is characterized in that the display device is automatically moved from its extended position to the retracted position as soon as the motor vehicle is stationary and a door is opened that provides direct access to an area of the interior containing the display device.

This ensures that the display device does not interfere with passengers entering or exiting the vehicle. This approach is particularly conceivable for automated vehicles that, like a taxi, transport several passengers boarding and alighting at short intervals, possibly unfamiliar with each other.

The method according to the invention also includes automatically moving the display device from its retracted position to the extended position as soon as all doors of the motor vehicle are closed and the vehicle starts moving. Such a method contributes to a further increase in comfort for passengers of the motor vehicle.

Preferred embodiments of the invention are illustrated in the figures and are explained in more detail in the following description with reference to the figures. This also makes further advantages of the invention clear. The same reference numerals, even in different figures, refer to the same, comparable or functionally identical components. Corresponding or comparable properties and advantages are achieved even if there is no repeated description or reference to them. The figures are not, or at least not always, to scale. In some figures, proportions or distances may be exaggerated in order to emphasize features of an embodiment more clearly.

• 2 the motor vehicle according to 1 , but with the indicator in a retracted position,
• 3 a detailed representation of the display device designed as part of a built-in module, in various positions,

• 5 the representation of another embodiment of the display device, in different positions.

First, the 1 Reference is made to this figure. This figure shows a motor vehicle K, which in the present exemplary embodiment is designed as an automatically driving motor vehicle. Passengers P1 and P2 are seated in an interior 10 of the motor vehicle K. They are seated opposite each other and are facing each other (in the direction of travel or against the direction of travel).

A display device 13 is arranged in the region of a roof lining 11 of the motor vehicle. The display device 13 has a first screen 13a and a second screen 13b.

The screens 13a, 13b form an articulated connection 14 at their mutually facing ends. In other words, the articulated connection 14 forms a common axis of rotation of the screens 13a and 13b, extending into the plane of the drawing.

Ends 13c of the screens 13a, 13b facing away from each other, however, are held in a forced guide not further numbered in this figure and can be moved towards or away from each other in adjustment movements B2.

It is indicated that the display device 13 can be designed as a component of an installation module 100 which is installed in the roof lining 11.

In the position shown, the display device 13 is in an extended position. In this extended position, the screen 13a faces the passengers P1 sitting in the area of a vehicle front F. The screen 13b faces the passengers P2 sitting in the area of a vehicle rear H.

Furthermore, it can be seen that the screens 13a, 13b, in the extended position shown (viewed from the side), form a V-shaped arrangement V with one another. The V-shaped arrangement V is designed in particular such that a surface normal N of the screens 13a, 13b falls approximately within the field of vision or head area of the passengers P1 and P2, respectively. This ensures particularly good visibility of the screen contents displayed on the screens 13a, 13b.

In the 2 A retracted position of the display device 13 is shown. It can be seen that the screens 13a, 13b (or housings enclosing the screens 13a, 13b) form a common plane E with one another in the retracted position of the display device 13. Preferably, the common plane E is parallel to the roof lining 11 and close to the roof lining 11 or is even flush with a surface of the roof lining 11.

In the figures, a further display device 13 is indicated by dashed lines, which is arranged in a side panel 12 of the motor vehicle K. In the present exemplary embodiment, the side panel 12 is a wall panel of the motor vehicle K. However, it is also conceivable that the side panel 12 is an interior panel of a door, for example a sliding door.

Based on the 3a -c the display device 13 will now be described in more detail.

As already mentioned, the display device 13 is designed as a component of a built-in module 100. A trough-like depression M is formed in the built-in module 100. A positive guide 19 is arranged in this depression M, which may, for example, be groove-like. The opposite ends 13c of the screens 13a, 13b are movably held in this positive guide 19. Connected to the ends 13c of the screens 13a, 13b are, in turn, preferably bolt-like drivers 13d, which in turn are movably coupled to threaded sleeves 16a and 16b.

The threaded sleeves 16a, 16b are in turn supported by a threaded rod 15.

The thread pairs of the threaded rod 15 and the threaded sleeves 16a and 16b are designed such that rotation of the threaded rod 15 results in an adjustment movement B1 in which the threaded sleeves 16a, 16b are moved towards or away from each other.

The adjustment movement B1 then leads in turn to the adjustment movement B2 of the ends 13c of the screens 13a, 13b in the forced guide 19. During the adjustment movement B2, the drivers 13d slide in the vertical direction within vertically projecting tubular parts of the threaded sleeves 16a, 16b.

Rotation of the threaded rod 15 can be accomplished via an electric motor 17, which has an integrated, unspecified control unit. The electric motor 17 is in turn connected to a connector 18 via a signal and control line. With the help of the connector 18 and with the help of locking elements (not shown in detail), the installation module 100 can be easily connected to an interior panel of the motor vehicle K in the roof lining 11 and/or in the side panel 12, as well as to an electrical system of the motor vehicle K.

When installed, the display device 13 can then be very conveniently moved from its extended position with a V-like arrangement V into its retracted position, in which the screens 13a, 13b form a common plane E (cf. 3a to 3c ). Of course, it is also possible to transfer the display device 13 from the retracted position to the extended position in a similar manner.

It should also be noted that in the retracted position ( 3c ) the screens 13a and 13b form a common plane E, which is approximately flush with a surface 21 surrounding the screens 13a, 13b. In the assembled state of the installation module 100, the surface 21 is in turn approximately flush with a surface 11a of the roof lining 11.

Based on the 4a -c, a further embodiment of a display device 13' will now be explained.

In contrast to the display device 13, the display device 13' has two screens 13a and 13b, which are not connected to each other at their mutually facing ends 13e. However, the screens 13a and 13b form a single display in their retracted position ( 4a) also form a common plane E with each other. The plane E is in turn approximately flush with a surface 23 surrounding the screens 13a, 13b. The surface 23 can be part of an interior panel or part of a built-in module accommodating the screens 13a, 13b.

In this example, too, the screens 13a, 13b cover recesses M1, M2 in their retracted position.

In the recesses M1, M2 there are again groove-like forced guides 19' in which opposite ends 13c of the screens 13a, 13b are forcedly guided.

In the extended position ( 3c ), the screens 13a, 13b again assume a V-like arrangement V with one another. Here, the screens 13a, 13b strike a stop formed by the recesses M1, M2 with their side facing away from the passengers or the interior 10. In the extended position, the screens 13a, 13b are also slightly recessed into the interior paneling, for example, into the roof lining 11.

The movement of the indicator device 13' from the extended position to the retracted position and vice versa (compare 4a to 4c ) is also carried out here by an electric motor not shown in detail.

Finally, the 5a -c a third embodiment of a display device 13" is explained. In contrast to the display device 13', the screens 13a, 13b are not partially recessed in a panel or in a built-in module. Rather, the screens 13a, 13b are in a retracted position ( 5a) on a surface 23 surrounding the screens 13a, 13b. The screens 13a, 13b in turn form a common plane E. The plane E is aligned parallel to the surface 23. The screens 13a, 13b rest against the surface with a surface facing away from the passengers, and the mutually facing ends 13e of the screens 13a, 13b lie close to one another or even touch one another.

The ends 13c of the screens 13a, 13b facing away from each other are in turn each held in a forced guide 19", which only allows the screens 13a, 13b to rotate R about an axis of rotation, wherein the axis of rotation runs perpendicular to the image plane and coincides with the ends 13c.

In an extended position ( 5c ), the screens 13a, 13b rest against a stop 24. However, the screens 13a, 13b also form a V-like arrangement V with one another.

The automatic adjustment of the indicator device 13" from a retracted to the extended position and vice versa (compare 5a to c) is also carried out here by an electric motor not shown in detail.

Finally, it should be noted that the described indicator devices 13, 13' and 13" in their retracted position are used to realize entry lighting or to create ambient lighting. For example, it is conceivable that the display device 13 installed in the roof lining 11 (see 1 ) emits a starry sky-like illumination into the interior of the motor vehicle K.
