Description

TECHNICAL FIELD

[0001] The invention relates to a motor vehicle with an adjustable display device, i.e. with a movable display device. A display device is understood to be an instrument, an instrument group or an instrument component designed for displaying image content, in particular a display. BACKGROUND

[0002] Displays in vehicles are increasingly large and are positioned at various locations in the vehicle cockpit. There is furthermore the desire for displays to be variably designed in terms of their size, for example to be implemented in a way that can be extended and retracted. Furthermore, they should be touch-operable, i.e. can be operated by touching on a touch-sensitive surface.

[0003] DE 102 015 011 614 A1 describes a display device for a motor vehicle, which has a flexible display and a linear guide, by means of which a first part of the display is guided.

[0004] DE 101 150 50 A1 relates to a display device, which comprises a flat screen and positioning means with which the flat screen can be moved into a desired viewing position.

[0005] From DE 102 014 006 338 A1 a display device for a motor vehicle is known, which has a housing with a channel, in which a display element is adjustably arranged, which has a first display area and a second display area, which is opposite the first display area, wherein the display element can be adjusted into a first position, in which the first display area protrudes from the channel, and into a second position, in which the second display area protrudes from the channel.

[0006] Extensible displays have the disadvantage that they are not sufficiently rigid, in particular when they consist of rigid and flexible parts. Touch-operability, i.e. operation by touching, is thereby made difficult, since flexible displays quickly bulge and do not provide resistance. SUMMARY

[0007] It is a basic task of the invention to provide a display device which has more stable and reliable touch-operability.

[0008] The proposed task is solved by the device according to the invention according to the independent patent claim. Advantageous refinements are given by the dependent claims.

[0009] The invention is based on the idea of providing a display device which not only has a display surface element which is flexible, but also a combination of a carrier which is flexible, i.e. bendable, and an additional linear guide. The display surface element is pulled by means of the guide element in the respective extended position to the track element in order to form a support over the entire plane of the track element. The track element is fixedly arranged in the interior space of the interior space panel element. The flexible, i.e. bendable, display is thus already taut in the process of extension and remains taut in the extended state, so that the touch operation is very simple. The construction is very stable and allows the display surface to be set to different sizes without loss of stability. By means of the forced coupling a stable support over the entire plane of the display, for example in different extended positions, is thus achieved and a reliable touch operation is thereby achieved.

[0010] The display device according to the invention has a display surface element which is flexible arranged in a housing. The housing can optionally be an interior space panel element of a motor vehicle, for example a switch panel or a hutze. The display surface element is understood to be a part or a group of parts which provides a surface for displaying image content. The display surface can be designed, for example, as a screen for projection or as a screen, preferably as an OLED screen. The flexible display surface element is understood to mean that it is not rigid or stiff, in other words is crimpable or foldable.

[0011] Furthermore, the display device has an adjustable carrier element, i.e. a part or a group of parts as a carrier, which is arranged in such a way that it can be adjusted, displaced or moved. The adjustable carrier element has a flexible and a rigid portion. The carrier element is arranged, for example glued, mounted or welded, with its front side flat on the rear side of the flexible display surface element.

[0012] The flexible portion of the carrier element is with respect to the adjustment plane of the carrier element, i.e. the plane in which the carrier element is moved out of or into the housing, arranged facing the interior space of the housing. The adjustment plane thus prescribes the direction of movement of the carrier element out of or into the housing. The adjustment axis and the axis of movement are also located in which the carrier element is displaced.

[0013] In other words, for example, the flexible half of the carrier element can be the portion which first sinks into the interior space of the interior space panel element when the carrier element is retracted and as the last comes out of the interior space of the interior space panel element when the carrier element is extended.

[0014] The rigid portion, which can also be called a support portion, is designed as a linear guide and is oriented or arranged with respect to the adjustment plane in the direction of the interior space panel element's outer environment. In other words, if the carrier element is extended, the first thing that comes out of the interior space of the interior space panel element is the planar, rigid portion of the carrier element, and it is the last portion to reenter the interior space of the interior space panel element when the carrier element is retracted.

[0015] The flexible portion of the adjustable carrier element has at least one guide element. A guide element is understood to be a part or component of the rear side of the carrier element that protrudes from the rear side, although it is arranged at the rear side. The guide element can be designed as a slider, a ball, or a knob, for example, in correspondence with this. Preferably, only the flexible portion of the adjustable carrier element can have the at least one guide element. In the case of this option, all guide elements can be detached from the rail, for example, when the display panel element (and thus the carrier element) is stored or stowed, whereby a still greater portion of the carrier element and thus the display panel element can be stowed very space-savingly.

[0016] Furthermore, the display device has a fixed guide device that has a support surface, preferably a flat or planar surface, arranged along the adjustment plane, which contains at least one rail element that extends along the adjustment axis. The at least one rail element is oriented such that, when the carrier element is adjusted, the at least one guide element is supported in the rail element along the adjustment axis and guided by the rail element. In other words, the arrangement of the rail element and the at least one guide element is coordinated such that, when the carrier element is extended, the at least one guide element is held at the fixed guide device by the rail element and guided along the adjustment axis. The disengageable form fit of the guide element and the rail element thus forms to place the carrier element in the desired position and at the same time to support and tension it.

[0017] The display device has an adjustment device that is designed for this purpose to control the change between the storage position of the display panel element (and thus between the storage position of the carrier element) and the display position of the display panel element (and thus of the carrier element) by moving or displacing or adjusting the carrier element. The storage position can also be called the stowage position, and is a position in which the carrier element with the display panel element is at least partially lowered into the interior space of the interior space panel element, for example, is rolled up. The display position or extended position is a position in which the carrier element is moved further along the adjustment axis out of the interior space panel element than in the storage position.

[0018] The advantages discussed above are achieved.

[0019] The strength of the display surface element, i.e. its stability, is produced in that a rigid linear guide of the carrier element supports the upper region of the display surface element, and the at least one guide element is held and oriented by the guide means, so that the flexible portion of the carrier element is also thereby tensioned. Since the flexible portion can be folded or rolled up, the carrier element with the display surface element can be stored very space-savingly in the storage position.

[0020] The carrier element can preferably have at least two guide elements which are arranged in a row along the adjustment axis. In other words, the carrier element can have at least two guide elements which form a row which extends along or parallel to the adjustment axis. Thereby, the display surface element is also better supported, without a higher space requirement in the storage position, or only a very slight additional space requirement through the additional guide elements.

[0021] In an improvement, the carrier element can have at least two rows of guide elements, in other words, the carrier element can be supported by one row of guide elements, for example, on the left and on the right, respectively. Thereby, the stability is also very much improved.

[0022] In a preferred embodiment form of the display device according to the application, the at least one rail element extends as a circular arc in the interior space of the housing. The guide element and thereby the carrier element are thereby guided along the guide element in the storage position or when being retracted or extended, however, so space-savingly that despite the guidance in the interior space of the interior space panel element no folding or bending occurs in the display surface element or in the carrier element.

[0023] The rigid portion of the carrier element and the flexible portion of the carrier element are preferably located in one plane, i.e. preferably form a stepless rear side of the carrier element. In other words, the carrier element (and thereby the combination of the display surface element and the carrier element) can preferably have the same thickness in the region of the rigid portion as in the region of the flexible portion. This is responsible for an even more stable form fit between the carrier element and the guide element. The form fit can be disentangled and thus ideally designed for touch operation of the size-adjustable display.

[0024] According to a further embodiment form of the display device according to the application, the at least one guide element can be arranged in such a way that it is located outside the rail element in the storage position and is guided into the deployed position when the carrier element is adjusted into the rail element. At a certain point in time thereby in the storage, the guide element or the guide elements is / are disengaged from the rail element, so that the flexible carrier element with the flexible display surface element can be stored even more space-savingly. This advantage occurs in particular if the at least one rail element does not have a circular arc in the interior space of the interior space panel element.

[0025] According to a further embodiment of the display device according to the application, the carrier element has at least two guide elements, wherein at least a portion of the guide elements are arranged such that they lie outside the track elements in the storage position and are guided into the respective track elements when the carrier element is adjusted into the display position. The advantages have already been discussed.

[0026] The task set out above is also solved by a motor vehicle having an embodiment of the display device according to the application. The motor vehicle according to the application is preferably designed as a motor vehicle, in particular as a passenger car or a utility vehicle, or as a passenger car or a motorcycle.

[0027] Improvements of the motor vehicle according to the application also belong to the application, which have features as they have already been described in connection with the improvements of the display device according to the application. For this reason, the respective improvements of the motor vehicle according to the application are not described again here.

[0028] The application also comprises combinations of features of the described embodiments. BRIEF DESCRIPTION OF DRAWINGS

[0029] Embodiments of the application are described below. To this end:

[0031] Figure 2 A schematic view in cross section of the first embodiment is shown, in which the display device can be seen in the display position; and

[0032] Figure 3 A schematic view of a further embodiment of the display device is shown, in which a partial view of the display device can be seen in a plan view. DETAILED DESCRIPTION

[0033] The embodiments explained below are preferred embodiments of the application. In the case of these embodiments, the described components of the embodiments exhibit respective individual features of the application, which are to be considered independently of one another, which respectively improve the application independently of one another. The disclosure should therefore also comprise combinations different from the illustrated combinations of the features of the embodiments. Furthermore, the described embodiments can also be supplemented by other features of the application already described.

[0034] In the figures, identical reference signs denote functionally identical elements.

[0035] Figure 1To illustrate the principle of a motor vehicle 10 according to the application, the motor vehicle can be designed, for example, as a passenger car, and a display device 12 according to the application in cross section.

[0036] The display device 12 has a housing 14, which has an opening 16 through which the combination of the carrier element 20 and the display surface element 18 can be extended and retracted from the housing. If the display device 12 is installed in the motor vehicle 10, the housing 14 can be, for example, an interior space panel element of the motor vehicle 10, for example a center console, a door panel, a switch panel or a cowling.

[0037] Figure 1 The display device 12 is shown in a position in which a portion of the display surface element 18 extends from the housing 14 through the opening 16. This can be, for example, already a storage position in which the display surface element 18 is set in a rest position. Alternatively, a larger part of the display surface element 18 or the entire display surface element 18 can be retracted into the housing 14 in the storage position.

[0038] The display surface element 18 can be designed, preferably, as a display with organic light emitting diodes ("Organic Light Emitting Diodes", OLED) and is flexible, i.e. it is bendable, pliable and rollable. Alternatively, the display surface element 18 can be, for example, a silver screen, and in the case of this option the display device 12 can additionally have a projector, which can be arranged in the motor vehicle 10 such that it projects an image onto the display surface element 18.

[0039] The display surface element 18 is arranged face-shaped at the carrier element 20, wherein the carrier element 20 is connected with a rear side of the display surface element 18. The front side of the display surface element 18 is the side at which a display content can be displayed, i.e. for example a projection surface or a screen surface. The front side 19 of the display surface element 18 can be preferably configured as a touch screen, i.e. a touch-sensitive surface or a touch-sensitive screen.

[0040] The carrier element 20 can, as in the example of Figure 1 consist of a pliable material, for example metal or plastic, over the entire face. In Figure 1In the example of Fig. 1, the carrier element 20 comprises a rigid, i.e. non- yieldable, portion 22 which can be arranged in a face-like manner in a recess of the upper portion. Here, the rigid portion 22 can consist, for example, of a more solid material or, for example, of a rigid plastic. The rigid portion 22 is located in the upper part of the carrier element 20, i.e. in that portion of the carrier element 20 which is first pushed out of the opening 16 when the carrier element 20 with the display surface element 18 is extended. Thereby, the entire upper portion is rigid. The rigid portion 22 serves as a linear guide and brings strength to the display surface element 18 in this upper region so that the display surface element 18 can be extended out of the housing 14 by means of the rigid portion 22.

[0041] Furthermore, Figure 1 The example of Fig. 1 shows an adjustment device 24 of the display device 12 which can comprise, for example, a motor and, for example, a lever 25 which can be fixed at the carrier element 20, in particular at the rear, inner end of the carrier element 20, in order to push the carrier element 20 and also thereby the display surface element 18 out of and / or into the housing 14. Here, an adjustment axis is predetermined which movement direction, in the example of Fig. 1, is upwards, i.e. out of the housing 14 through the opening 16 or into the housing 14. The exemplary lever 25 can be adjusted by means of the motor in order to extend the carrier element 20, for example, to 90 degrees so that, then, in the unfolded position, the carrier element 20 with the display surface element 18 is extended out of the housing 14 as shown in Fig. 2. Alternatively, in order to move the carrier element 20, the adjustment device 24 can have, for example, a rope drive or a pulley block or other possibilities for moving the display known to the person skilled in the art from the prior art. Figure 1 Figure 2 The example of Fig. 1 shows an adjustment device 24 of the display device 12 which can comprise, for example, a motor and, for example, a lever 25 which can be fixed at the carrier element 20, in particular at the rear, inner end of the carrier element 20, in order to push the carrier element 20 and also thereby the display surface element 18 out of and / or into the housing 14. Here, an adjustment axis is predetermined which movement direction, in the example of Fig. 1, is upwards, i.e. out of the housing 14 through the opening 16 or into the housing 14. The exemplary lever 25 can be adjusted by means of the motor in order to extend the carrier element 20, for example, to 90 degrees so that, then, in the unfolded position, the carrier element 20 with the display surface element 18 is extended out of the housing 14 as shown in Fig. 2. Alternatively, in order to move the carrier element 20, the adjustment device 24 can have, for example, a rope drive or a pulley block or other possibilities for moving the display known to the person skilled in the art from the prior art.

[0042] The disengageable form fit between the carrier element 20 and the housing 14 takes place by the bearing of the guide element 26 in the track element 28 of the guide device 30.

[0043] The track element 28 can preferably be designed as a rail or a groove. The guide element 26 can then preferably be designed as a ball or a right-angled parallelepiped and the shapes of the guide element 26 and the track element 28 are ideally coordinated with one another so that the guide element 26, although form-fittingly supported in the track element 28, can nevertheless be moved along the adjustment axis within the track, i.e. in the movement direction.

[0044] In addition to the track element 28, the guide device 30 also comprises a linear guide 32 against which the rigid portion 22 of the carrier element 20 can rest in the storage position (Fig. 1) and against which the yieldable portion of the carrier element 20 with the guide element 26 can rest in the unfolded position (Fig. 2). Figure 1 Figure 2 In addition to the track element 28, the guide device 30 also comprises a linear guide 32 against which the rigid portion 22 of the carrier element 20 can rest in the storage position (Fig. 1) and against which the yieldable portion of the carrier element 20 with the guide element 26 can rest in the unfolded position (Fig. 2).​​

[0045] Figure 2 The carrier element 20 is shown after it has been pushed out by the adjustment device 24. The guide elements 26 are located in the track elements 28 almost exclusively in the linear region of the track elements 28, and the rear side of the carrier element 20 with its pliable portion is held and stabilized in the track elements 28 and by the linear guide 32 in a form-fit manner by the guide elements 26.

[0046] The track elements 28 are designed according to Figure 1 and Figure 2 the example of a circular-arc shape are responsible for the fact that the carrier element 20 can be retracted into the housing 14 in the storage position and stored space-savingly.

[0047] Figure 3 A top view of the carrier element 20 is shown in the region in which the entire thickness of the carrier element 20 is pliable. Figure 3 An exemplary embodiment is shown according to which the carrier element 20 can have two or more rows of guide elements 26, wherein the guide elements 26 are designed, for example, as spheres on one side and as right parallelepipeds on the other side. Alternatively, however, each of the guide elements 26 can be designed as a sphere or as a right parallelepiped. Figure 3 For illustration, in particular, the guide elements 26 can be designed to fit or approximately fit the respective track element 28, i.e. can be supported in the track elements 28 in such a way that they are held in a form-fit or approximately form-fit by the track elements 28, although they are movable as soon as the adjustment device 24 causes a change between the storage position and the deployed position.

[0048] Overall, the example shows how an assembly for a pliable display face element 18, in particular a flexible display, can be provided.

[0049] In an assembly for a flexible display, for example, which can be extended, for example, a flexible display carrier is coupled with a linear guide. The carrier element 20, i.e. for example the display carrier, can be pushed, for example, by the adjustment device 24, for example by a motor and simple kinematics.

[0050] Furthermore, a plurality of guide elements 26 is preferably present at the carrier element 20, which run to a second guide unit, i.e. the guide device 30. The guide line of the track elements 28 here transitions from a circular arc to a linear portion. The second guide unit has the task of preventing possible bulging of the flexible carrier.

[0051] In the different extended positions, a stable support of as much of the plane of the exemplary display as possible is achieved, and thus a reliable touch operation is achieved.

[0052] The overall unit has a robust configuration and stable and reliable touch operation.
