Description

[0001] The present invention relates to a means of transport with a display that can be folded or rolled up.

[0002] Displays in vehicles are known in the prior art for displaying information or (designed as touchscreens) for receiving user input. These displays allow access to entertainment functions as well as comfort and vehicle settings.

[0003] Furthermore, initial approaches to foldable or rollable displays are now known in the prior art, promising a particularly innovative form factor for portable mobile user devices (e.g., tablets and smartphones). Such displays are illustrated, for example, in the following disclosure: https: / / www.mib-terminal.de / produkte / video-walls / led-glastransparent?gclid=CjwKCAjw3MSH Bh B3EiwAxcaEu1KGiDHZTJhaCrG6KucGcl m6fbWSal-T3j1R_aKVAvDb1wCh81T-FBoCh9kQAvD_BwE

[0004] Based on the aforementioned prior art, it is an object of the present invention to better adapt the display of information in the means of transport to the requirements prevailing in the means of transport.

[0005] The problem identified above is solved according to the invention by a means of propulsion according to claim 1. The dependent claims describe preferred embodiments of the invention.

[0006] The means of transport can be, for example, a car, van, motorcycle, truck, aircraft, and / or watercraft. A base or mount is arranged on a surface within the interior of the means of transport. This interior surface can be, for example, a dashboard, center console, A-pillar, B-pillar, headliner, or similar. The base is designed to hold a foldable or rollable display. In other words, the foldable or rollable display is embedded in the interior surface via the base and rigidly connected to it. This connection does not impede the display's rollability or foldability. Rather, the foldable or rollable display retains its ability to fold or unfold individual sections of the display.The display area can be tilted or swiveled relative to other areas of the display surface, for example, by a total angle of at least 90° or more. In particular, certain areas of the display can be swiveled or folded by approximately 180° or more. A first part of the display can also be rolled or folded by, for example, 270°, 360°, or 450° relative to a second surface area of ​​the display. This results in a particularly flexible arrangement of a display protruding from the surface of the vehicle's interior, enabling flexible targeting of individual occupants as well as a particularly crash-resistant, due to its compliant design.

[0007] The base can incorporate a lifting mechanism for recessing the display into the interior surface or interact with such a mechanism. In other words, the base is either integrated into the lifting mechanism (or its moving part) or also supports the lifting mechanism for recessing the display. This allows the display to achieve an additional degree of freedom beyond its foldability or rollability, enabling it to be partially or completely recessed into the surface. Alternatively, the base can also mount the display rigidly or allow it to swivel. In other words, the display can be rotated around a horizontal and / or vertical axis. These additional degrees of freedom can further enhance the flexibility of using the display in vehicles.

[0008] If the display is intended for multiple users within the vehicle, it can be designed, for example, to generate digital information when the display is folded or rolled, allowing the content to be modified. In other words, a section can be pivoted from one relative position to another, triggering a sensor to send a signal representing the transition. This sensor signal can then be interpreted as indicating that a different person wants to view the display, necessitating an automatic adjustment. For instance, the first person might be sitting farther away from the display than the second, allowing the content to be adjusted to reflect the changed viewing distance.For example, more and smaller details can be displayed on the screen, so that the second user sees a larger section of text at a reduced screen size than the first user. The first and second positions can also be predefined to display different content / information. For instance, the first position could be assigned to the driver of the vehicle, who might be interested in route-specific information, while a passenger in the second position would only want to consume entertainment-specific content, as they have no influence on the vehicle's operation.Thus, for example, when switching from the first to the second position, a split-screen operating mode can be activated or deactivated, the scale of the displayed content can be increased or decreased, content can be moved relative to its position on the display, or additional information can be added or hidden. All of this can happen automatically and, in particular, depending on a user-specific configuration of the vehicle. This reduces the number of steps required when swiveling the display from the first to the second position, allowing the user to refocus more quickly on the road ahead.

[0009] If the displayed content has changed when switching from the first to the second position, the content previously displayed in the first position can be shown again, or the operating mode can be started, when the display position is changed back to the first position. In other words, depending on the display position, the display switches between the first content assigned to the first position and the second content assigned to the second position, corresponding to the respective position.

[0010] The display, or an integrated sensor, can detect the transition from the first to the second position. Upon receiving this notification (e.g., an electronic signal), an imaging unit (head unit or electronic control unit) can determine the required display content (particularly based on a configuration file) and send it to the display. The sensor that detects the transition between the first and second positions could be, for example, a camera, a position sensor, a force sensor, a deformation sensor, or any other suitable sensor. A light sensor or a microphone could also be used to adjust the display content based on a change in transmission characteristics. The sensor could be located, for example, within the display housing or at its edge.This results in a slim design and a compact assembly for permanent integration into the surface of the means of transport.

[0011] When the present invention refers to rolling (rolling in or unrolling) or folding, pivoting, or collapsing the display, this refers in particular to a process in which the display surface at least partially leaves or re-enters a common plane in which it was not previously located. For example, the display is bent, folded, or twisted to give at least a portion of one of its surface normals a different orientation than before. In this way, a particularly flexible and therefore crash-resistant display surface can be provided, since it yields quickly, without splintering, and to a large extent upon impact, thus preventing such severe consequences as in the prior art.

[0012] For example, the display can be folded, rolled, or bent / folded by a motor. The motor can be an electric motor and / or a piezoelectric motor. In particular, a signal from a pre-crash safety system can be used to control the motor and / or to roll or fold the display, thus minimizing its silhouette / exposure potential in the event of a crash.

[0013] For example, the display can react almost automatically to a changing viewing situation. For instance, if a user previously viewing the display looks away, a portion or all of the display can be automatically reoriented within the vehicle. This could, for example, maximize the projection area from the perspective of a second user by aligning the display surface normal towards them. An interior camera (especially one integrated into the display housing), another sensor, a speech processing system, or a different user interface could detect that a second user intends to use the display from a different location. Either an explicit or implicit command from the user can then trigger the display to adjust to their position.This allows the same display area to be used ergonomically in different positions within the vehicle. The sensors already present in the vehicle for identifying the person currently most interested in viewing the display can be used for this purpose, as can sensors integrated into the display itself, its frame, or its housing (alternatively or additionally).

[0014] Depending on its position and application, the display can also feature matrix displays on opposing surfaces / sides, which can be switched between a first and a second display, or between an activated and a deactivated mode, depending on the folding state. For example, a display suspended in an A-pillar, when rolled around the A-pillar, can function as a (partially) transparent A-pillar by displaying images captured by a camera on one side of the rolled-up display, while in a second position, areas on a second (opposite) side of the display located within the driver's primary or secondary field of vision are used to display other information (e.g., route instructions / commands). The applications for a display according to the invention can be further expanded in this way.

[0015] To further improve crash safety in conjunction with a display according to the invention in a vehicle according to the invention, the display can include an airbag, which can be arranged, in particular, in an edge of the display and / or in a base of the display. In other words, an air-filled flexible bag can be deployed / blasted out of the edge and / or the base, which, in the event of a user impacting the display, distributes the resulting forces and thus reduces the risk of injury to the user. The deployment of the airbag can also be based on crash sensors or pre-crash sensors, whereby the roll-up or fold-up function of the display can be controlled alternatively or additionally to reduce the silhouette and the probability of injury.

[0016] Further details, features, and advantages of the invention will become apparent from the following description and the figure. The figure shows a perspective view of a driver's workstation of a means of transportation designed according to the invention, featuring different displays.

[0017] The figure shows a car as a means of transport 10, in whose dashboard 4 a first rollable display 2 is held by means of a base 1. The base 1 is flush with the surface of the dashboard 4 and holds a lower part of the display 2. In a first (deactivated or rolled-up) position, the display 2 is not in the user's primary or secondary field of vision. Upon detection of the display 2, an actuator / motor can move the display 2 into an upright position, in which the display 2' also directs a camera 6 towards the viewer. If the viewer sees the content displayed on the display 2 or 2', the display 2 or 2' can remain in the unfolded (shown with dashed lines) position.If the displayed content is no longer visible to the current viewer, the display can swivel in a different direction, tilt, or switch to a rolled-up configuration. Additionally, a second display 2 is arranged on the A-pillar 3, which follows the convex contour of the A-pillar 3 to provide a function also called the "transparent A-pillar." In this position, a section of a curb 5 located behind the A-pillar 3 is displayed as content 5b' by the first side of the display 2. The position of the displayed content can be determined using the camera 6 or another camera located inside the vehicle 10. For this purpose, the position and orientation of the user's attention (not shown) can be determined, and the environmental features located behind the A-pillar 3 (e.g., curb 5) can be captured using a front camera (not shown).The display content 5b' can now be positioned, scaled, and colored to correspond to the curb 5 visible through the windshield. In a second position, swiveled in front of the windshield base, the dashed display 2' serves as the windshield base display, with the opposite side of display 2' used to show navigation instructions 5a'. The navigation instructions 5a' can be displayed automatically when display 2 is swiveled into the position of display 2', at which point display content 5b' is deactivated to prevent reflections in the windshield. Swiveling can be motorized or manual. Other possible positions for displays 2 include the headliner, the rearview mirror, etc.its base, the center console, the B-pillar, the C-pillar, or, for example, the headrests and backrests of the first or second row of seats.
