Description

The invention relates to a display device for a motor vehicle according to the preamble of claim 1. Furthermore, the invention relates to a method.

An integration of advertisements for entertainment media or rear-seat entertainment for vehicles, in particular for the entertainment of rear-seat passengers and thus for realizing a high level of travel comfort, has so far only been solved to a limited extent. Today's displays usually have display surfaces that are designed, for example, as LCD, OLED or plasma displays and display screen information. In the case of mobile devices such as cell phones in particular, there is usually a dilemma between the size of the display or screen and the size of the cell phone itself in order to be able to operate, hold and / or stow the device easily and conveniently. The first mobile phones with collapsible or foldable displays are already on the market, in which in particular the user is able to manually fold and unfold them.

From the DE 10 2015 015 694 B3 a method for operating a display device for a motor vehicle is known, in which objects are displayed on a touch-sensitive and foldable display device of the display device. As a first step, at least one folding of the display device is carried out by a user. Furthermore, as a second step, the objects are displayed on at least one main surface of the display device, as well as on at least one side surface of the display device arranged at an angle to the main surface, depending on the folding.

It is the object of the invention to create a display device and a method so that particularly advantageous operation can be implemented.

This object is achieved by means of a display device and by a method having the features of the independent patent claims. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

The display device according to the invention for a motor vehicle, in particular for a passenger car, comprises at least a first surface segment and a second surface segment, which are connected to one another, in particular articulated, by means of a folding mechanism arranged on a rear side of the display device. The folding mechanism is designed to adjust the surface elements relative to one another and thus the display device between a use position in which the surface segments form a common display surface of the display device and a stowed position in which the surface segments are at least essentially folded over one another. The common display area is to be understood as meaning in particular that the first area segment forms or has a first part of the display area and the second area segment forms or has a second part of the display area, the parts being arranged next to one another in the position of use and forming the display area together or together. In particular, the parts designed as surface parts are arranged, for example, in a common plane in the position of use, it being possible for the respective part, for example, to be at least substantially flat. The display surface is then flat, for example. However, it is also conceivable that the respective part is curved or arched, so that the display surface can be curved or arched or can have the curved or arched parts. In this case, especially in the position of use, the rear side of the display surface is turned away. Thus, for example, the first surface segment forms a first rear side part of the rear side, and the second surface segment forms, for example, a second rear side part of the rear side. In the position of use, the rear side parts are arranged, for example, next to one another and together or together form the rear side. The respective rear side part faces away from the respective part of the respective area segment, also referred to as the display part or the display area part.

In order to be able to realize a particularly advantageous folding and unfolding of the display device and thus a particularly advantageous operation of the display device, in particular automatically or without external influence by a person, it is provided that the folding mechanism comprises an inflatable air element. By changing the volume of the inflatable air element, the display device can be adjusted between the position of use and the stowed position.

For example, to move the display device from the stowed position to the use position, a fluid such as a gas, in particular air, is introduced into the air element, which increases the volume of the air element, thus increasing the volume of the air element. For example, in the position of use, the volume of the air element is maximized by supplying air, as a result of which the air element is particularly stiff. As a result of the increase in volume, for example, the surface segments are unfolded. For example, in order to move the display device from the position of use to the stowed position, the fluid is discharged from the air element or the fluid is allowed to flow out of the air element. As a result, the volume of the air element is reduced, and consequently a volume reduction or reduction in size of the air element is effected. As a result, the surface segments are collapsed or collapsed, or the surface segments can be folded up or together. For example, the air element is elastically tensioned or stretched in the position of use, so that the air element contracts, in particular automatically, when the fluid is removed from the air element or the fluid is allowed to flow out of the air element.

For example, the air element is connected to the surface segments, in particular in such a way that a tensile force can be transmitted from the air element to the respective surface segment. For example, when the air element contracts as a result of the fluid being discharged from the air element, the air element exerts a respective tensile force on the surface segments that are initially unfolded, by means of which the surface segments are folded together or on top of one another. As a result, the display device is adjusted from the position of use to the stowed position. The air element is formed, for example, from an elastically deformable material, in particular from an elastically deformable plastic such as rubber. It can thus be provided that the air element is elastically tensioned or stretched in the position of use, so that the air element provides the aforementioned tensile force as a spring force, by means of which the surface segments are folded onto one another when the fluid is discharged from the air element or flows out .

Furthermore, it is conceivable that at least one spring element provided in addition to the air element is provided, which is tensioned at least in the position of use and thereby provides a spring force. The spring force acts, for example, at least indirectly, in particular directly, on the surface segments. As a result of the removal of the fluid from the air element, the surface elements that are in the position of use and thereby initially unfolded can be folded up. An essentially stepless adjustment of the display device that is gentle on the display surface can be implemented. The air element can, for example, be cylindrical and / or tubular and thus designed as an air hose and arranged essentially transversely to a folding or pivoting axis of the display device, also referred to as an adjustment axis, whereby the stiffening or the increase in volume of the air element opens the surface segments. For example, the air element, in particular at least in the position of use, has a direction of longitudinal extent which runs obliquely or perpendicularly or parallel to an adjustment axis, also known as the pivot axis, about which the surface segments can be pivoted relative to one another when the display device is adjusted between the stowed position and the position of use, that means that they can be folded apart and on top of each other. Furthermore, it is conceivable that the air element is designed as an air cushion or has another shape.

It is conceivable that the fluid flows out of the air element by allowing the fluid to flow out of the air element and as a result the air element contracts, in particular independently. Alternatively or in addition, it is conceivable that the fluid is actively conveyed out of the air element, in particular sucked off, by means of at least one pump. In this way, for example, the volume of the air element is minimized in the stowed position, so that the installation space requirement can be kept particularly low. For example, the air element itself is flexible or limp so that, for example, the air guide element, in particular as a result of the removal of the fluid from the air element, is foldable and can be folded up with the folding mechanism. In addition, especially by using the pump, a speed at which the volume change takes place can be adjusted depending on use or need, whereby, for example, the adjustment to the stowed position can be adapted to a predetermined time for shutting down or switching off the display device. In particular, in addition to the position of use and the stowed position, the display device can also have further positions or positions, whereby the air element can participate as a component of the display device to be set in stiffening or in increasing the volume.

An advantageous embodiment provides that the inflatable air element is designed to lie flat on the rear side in the stowed position. In other words, it is preferably provided that the air guide element rests flat on the rear side in the stowed position. As a result, the space requirement can be kept particularly low will. In addition, due to the flat contact, a particularly high number of surface segments of the display device, compared to two larger numbers, can be folded together in a space-saving manner in the position of use, so that the display surface is particularly large in the position of use, but the display device in the stowed position only requires little installation space. In the position of use, the air guiding element can lie flat against the rear side and be flat or curved. The air element is preferably formed from an at least partially flexible, in particular flexible, material. The at least partially flexible material of the air element essentially avoids any impairment of the folding process. In particular, the folding or a folding arrangement of the surface segments is at least partially variable.

A further advantageous embodiment provides that the display device is designed to control the change in volume of the air element by means of an included electrically operated pump. In other words, it is preferably provided that the display device has a pump or the aforementioned pump, by means of which the fluid is to be conveyed into the air guide element and / or out of the air guide element. Alternatively or additionally, an electronic computing device, in particular the display device, can be provided, which can control the pump and thereby control or regulate, whereby the fluid is to be conveyed into and / or out of the air guiding element by means of the pump. The pump is fluidically connected to the air element, for example, by means of a line element designed in particular as a hose. The pump is designed, for example, to both convey air, in particular via the line element, into the air element, and to convey air, in particular via the line element, out of the air element, in particular to suck it off. By means of the pump and the folding mechanism, in particular by setting different volumes of the air element, the display device can also be adjusted to at least one or more, further and in particular positions different from the position of use and the stowed position, for example between the stowed position and the position of use will. The surface segments of the display device can be adjusted to one another at a certain angle. In other words, in the respective further position, the surface segments enclose, for example, an angle with one another which is smaller or larger than 180 degrees. For example, in the respective further position, the surface segments can be held or fixed relative to one another by means of the air element. Furthermore, it is conceivable that the surface segments are held in the use position and / or in the stowed position, in particular exclusively, by means of the air element. Furthermore, it is possible that at least one, in particular mechanical, fixing device provided in addition to the air element is provided, by means of which the surface segments are held in the use position and / or in the stowed position and / or in the further position relative to one another, that is, locked or are fixed. The fixing device can, for example, lock the surface segments in a form-fitting manner relative to one another. Furthermore, it is conceivable that the fixing device has a magnet, in particular a permanent magnet, which provides or can provide a magnetic field. By means of the magnetic field or by means of a magnetic force resulting from the magnetic field and acting at least indirectly, in particular directly, on the respective surface segment, the surface segments can be locked relative to one another.

In a further embodiment it is provided that the common display surface and thus the first surface segment and the second surface segment form a planar surface in the position of use. In this way, for example, a person staying in the interior of the motor vehicle, such as the driver of the motor vehicle or a rear passenger who is looking at the display area, can have a complete view of the display area, thereby avoiding reflections and shadows that could result from angled surface segments. In particular, the volume of the air element is minimal here, so that when there is a change in volume, the adjustment is initiated, for example, into the stowed position.

Another embodiment provides that the inflatable air element is designed as a spring element. This can be implemented, for example, in that the air element - as described above - is formed from an elastically deformable material or the aforementioned elastically deformable material. The spring element is, for example, tensioned at least in the position of use and can thereby provide a spring force at least in the position of use, which acts at least indirectly, in particular directly, for example as a tensile force on the respective surface segment. The surface segments can be folded onto one another by means of the spring force, as a result of which the display device is moved from the position of use into the stowed position. Furthermore, for example, the spring element can dampen a shock acting on the display device, in particular on its rear side. This in particular prevents damage to the display device, in particular any sensitive edges of the display device that may be provided, for example in the case of a Unfolding due to outside influence. Furthermore, it is conceivable that when the display device is fixed on a corresponding component of the motor vehicle by means of the spring element, vibrations of the display device can be damped.

In a further embodiment it is provided that the inflatable air element is non-destructively detachable, in particular fixed on the respective surface segment and / or on the rear side, whereby an exchange of the air element is possible. In the event of possible damage, it is possible for a fitter to carry out an exchange without having to replace the entire display device.

In a further embodiment it is provided that the display device comprises at least one second inflatable air element, the second inflatable air element being attached or arranged at a predetermined distance from the first inflatable air element. The previous and following statements on the first air element can easily be transferred to the second air element and vice versa. It is conceivable that the pump is a pump common to the air elements, by means of which the fluid is to be conveyed into the air elements and / or out of the air elements. Furthermore, it is conceivable that the air elements or their longitudinal extension directions run at least substantially parallel to one another.

Both air elements can, for example, be attached or run linearly, in particular in a straight line, along respective outer edges of the surface segments, in particular facing away from one another, as a result of which the surface segments can be opened particularly well. Furthermore, an area or an intermediate space can be arranged between the air elements, in which or in which at least one or more further components of the display device such as, for example, cabling or connecting hoses can be arranged. The air elements can be fluidically connected to one another and / or, in particular directly, to the pump of the display device by means of the connecting hose or the connecting hoses.

Another embodiment provides that the display device comprises at least one closure element which is designed to hold the display device in the stowed position. The closure element can be used, for example, to prevent the surface segments from being opened up by external influences. The closure element is, for example, the aforementioned fixing device or part of the fixing device.

In a further embodiment it is provided that the display device comprises at least one holding element which is designed to hold the display device in the position of use. Analogous to the closure element, the holding element can hold the display device in the position of use by means of a mechanism or a magnetic force, which prevents it from being opened or closed by external influences. The inflatable air element can also be protected by the holding element, since undesired adjustment of the display device without the associated change in volume is prevented. The holding element can be the aforementioned fixing device or a component of the fixing device.

In a method according to the invention for adjusting a display device, in particular according to the invention, for a motor vehicle, at least a first surface segment and a second surface segment of the display device are arranged between a Adjusted the use position and a stowage position. In the position of use, the surface segments form a common display surface of the display device. In the stowed position, the surface segments are at least essentially folded over one another

In order to be able to implement a particularly advantageous operation of the display device, it is provided that the surface segments are adjusted between the use position and the stowed position by means of a change in volume of an inflatable air element of the folding mechanism. Advantages and advantageous configurations of the display device according to the invention are to be regarded as advantages and advantageous configurations of the method according to the invention, and vice versa.

Further features of the invention emerge from the claims, the figures and the description of the figures. The invention will now be explained in more detail using preferred exemplary embodiments and with reference to the drawings. It shows:

• 2 a schematic sectional view of a second embodiment of the display device with three surface segments in the use position and in the stowed position.

1 shows in a schematic sectional view a first embodiment of a Display device 10 for a motor vehicle, in particular for a passenger vehicle. This means that the motor vehicle in its fully manufactured state has the display device 10 has, which is arranged, for example, in the interior of the motor vehicle, also referred to as the passenger compartment. The display device 10 has at least or exactly two surface segments in the first embodiment 12th , 14th on, where the area segment 12th also as the first area segment 12th and the area segment 14th also as a second area segment 14th referred to as. The surface segments 12th , 14th are by means of a folding mechanism 16 the display device articulated to one another and thereby about a pivot axis, also referred to as a folding axis 30th relative to each other between a position of use G and a stowage V pivotable, that is, foldable. The folding mechanism is on a rear 20th the display device 10 arranged and designed that the display device 10 between the position of use G and the stowage V can be adjusted. The surface segments form 12th , 14th in the position of use G a common display area 22nd the display device 10 , which is a planar surface or is arranged in a plane and a flush or uninterrupted image for a viewer of the display surface 22nd can represent. This is to be understood in particular that the display area 22nd preferably without interruption via the pivot axis 30th stretched away. Thus, for example, is the display area 22nd a foldable or bendable electronic display or formed by such a foldable or bendable electronic display, which is also referred to as a display. In the position of use G are the

Surface segments 12th , 14th arranged next to one another, in particular along a perpendicular to the folding axis (pivot axis 30th ) running first direction.

In the stowage position V however, both are area segments 12th , 14th at least partially, in particular at least predominantly or completely, folded over or on top of one another, in particular along a second direction running perpendicular to the folding axis and perpendicular to the aforementioned first direction. In this way, for example, the display device 10 , in particular by means of a stowage mechanism of the motor vehicle, can be stowed in a space-saving manner in a storage space provided for this purpose, such as a drawer, for example.

To a particularly advantageous operation of the display device 10 to be able to realize, has the folding mechanism 16 at least or exactly one inflatable air element 18th on, by the change in volume the display device 10 between the position of use G and the stowage V is adjustable. This change in volume can be monitored by one of the display devices 10 assigned, for example electrically operable and / or electrically controllable and thus controllable or regulatable pump 24 be effected which part of the display device 10 can be. For example, to increase the volume of the air element 18th to effect and thereby, for example, the display device 10 from the stowage V in the position of use G can be adjusted by means of the pump 24 Air into the air element 18th be promoted. This creates the air element 18th inflated. Alternatively or additionally, it is conceivable that by means of the pump 24 Air from the air element 18th can be conveyed out, in particular sucked off. This reduces the volume of the air element 18th causes the display device 10 from the position of use G in the stowage position V is adjusted.

For example, in the position of use G the volume of the air element 18th maximized by supplying air, eliminating the air element 18th stiffened and the two surface segments 12th , 14th unfolds and firmly in the position of use G being held. By evenly supplying or introducing air into the air element 18th can be an at least substantially stepless and thus gentle adjustment of the display device 10 be made. The air element 18th can, for example, in particular at least in the position of use, be at least substantially cylindrical and / or tubular or else cuboid.

The air element 18th is here on a first outer edge 26th of the first surface segment 12th and on a second outer edge 28 of the second surface segment 14th attached and / which extends, for example, in particular continuously, from the outer edge 26th up to the outer edge 26th facing away from the outer edge 28 , where the respective outer edge 26th , 28 for example opposite a respective folding edge of the respective surface segment 12th , 14th is arranged. For example, the hinged edges face one another. The pivot axis 30th is arranged on or between the hinged edges. Here are the surface segments 12th , 14th Can be folded in a wing-like or wing-like manner relative to one another. The air element 18th or its longitudinal extension direction, in particular running along the first direction or parallel to the first direction, is at least substantially transverse, that is to say perpendicular to the respective folding edge or to the pivot axis 30th the display device 10 arranged. For example, is a first end 32 of the air element 18th on the first outer edge 26th of the area segment 12th fixed, and a second end 34 of Air element 18th is for example on the second outer edge 28 of the area segment 14th fixed. It is possible to use the air element 18th on the respective folding edge of the respective surface segment 12th , 14th to fix in order to achieve a particularly high stability of the display device 10 to realize. In particular, it is provided that the air element 18th non-destructive detachable on the back 20th or on the respective surface segment 12th , 14th is fixed, thereby replacing the air element 18th is possible.

As preferably for adjusting the display device 10 in the stowage position V Air from the air element 18th is sucked off, whereby its volume is reduced, the air element lies 18th in the stowage position V for example, strip-shaped and / or flat on the back 20th the display device 10 or the surface segments. Here is the air element 18th flexibly foldable and can therefore by means of the folding mechanism 16 be folded or folded up with the surface segments 12, 14. Furthermore, a second inflatable air element 42 can be provided, which is at a distance from and / or at least substantially parallel to the first air element 18th and is attached. The inflatable air elements can be connected to one another or directly to the pump by means of at least one or more connecting elements, in particular connecting hoses 24 the display device 10 be fluidically connected.

It is conceivable that the surface segments 12th , 14th in at least one, from the position of use G and that of the stowage V different, additionally provided position can be moved, in particular by means of the air element 18th . The surface segments 12th , 14th for example by means of the air element 18th and / or by means of an in addition to the air element 18th provided fixing device in the position of use G and / or the stowage V and / or the further position are held relative to one another, whereby in the use position G , the stowage V and / or the further position unwanted relative movements between the surface segments 12th , 14th are avoided.

The inflatable air element 18th is also used as a spring element 36 educated. Here, for example, is the air element 18th formed from an elastically deformable material, in particular rubber. The spring element 36 is at least in the position of use G elastically stretched or stretched and thereby puts an at least indirectly, in particular directly, on the surface segments 12th , 14th acting and acting as a restoring force spring force ready. Will the air out of the air element 18th sucked out, the air element can 18th relax independently, whereby the surface segments 12th , 14th be collapsed or collapsed by means of the restoring force. Alternatively or additionally, it is conceivable that the display device 10 about the spring element 36 is held on a corresponding component, in particular in the interior. Thus, for example, by means of the spring element 36 Vibrations of the display device 10 are transmitted or by means of the spring element 36 it can be avoided that vibrations of the component are excessively transmitted to the display device 1 β.

The display device 10 comprises at least one closure element 38 , which is, for example, part of the fixing device and the display device 10 or the surface segments 12th , 14th relative to each other in the stowage position V holds. The display device also includes 10 a retaining element 40 , which is, for example, part of the fixing device and the display device 10 or the surface segments 12th , 14th relative to each other in the position of use G holds. Both the closure element 38 as well as the holding element 40 can, for example, the surface segments 12th , 14th mechanically, in particular positively and / or frictionally, and / or magnetically, that is, hold them relative to one another by magnetic force, that is to say fix them, thereby preventing folding and unfolding due to external influences. In addition, by means of the holding element 40 can the air element 18th be protected, as a forcible adjustment of the display device 10 is prevented without the associated change in volume.

2 shows in a schematic sectional view a second embodiment of the display device 10 which at least or exactly a third surface segment 44 includes. The surface segments 12th , 14th , 44 are by means of the folding mechanism 16 articulately coupled to one another in such a way that the surface segments 14th , 44 around a second pivot axis 50 are pivotable relative to each other. The pivot axis 50 is from the pivot axis 30th spaced and runs parallel to the pivot axis 30th . In the position of use G are the surface segments 12th , 14th , 44 arranged side by side along the first direction, and in the stowed position V are the surface segments 12th , 14th , 44 arranged one above the other or on top of one another along the second direction.

the end 1 it can be seen that in the first embodiment in the stowed position the surface segments arranged on top of one another 12th , 14 are arranged between the air element. The second embodiment is in the stowed position V the folded surface segments 12th , 14th , 44 between the air element 18th arranged, the surface segment 12th between the surface segments 14th and 44 is arranged, and wherein a part of the air element 18th between the surface segments 12th , 44 is arranged. The air element 18th is for example on the first outer edge 26th of the first surface segment 12th and on a third outer edge 48 of the third surface segment 44 attached, with the outer edges 26th , 48 of the respective folding edges of the three surface segments 12th , 14th , 44 are turned away. For example, the folding edges of the surface segments 12th , 14th and the folding edges of the surface segments 14th , 44 facing each other or adjoining each other. In particular, it is conceivable that the surface segments 12th , 14th , 44 formed separately from each other and by means of the folding mechanism 16 are articulated to one another, or the surface segments 12th , 14th , 44 are formed integrally with one another, so that, for example, the folding mechanism 16 through the surface segments 12th , 14th , 44 is formed or part of the surface segments 12th , 14th , 44 is. In particular, the first end 32 of the air element 18th on the first outer edge 26th and the second end 34 of the air element 18th on the third outer edge 48 be fixed.
