Description

[0001] Swivel screen

[0002] The invention relates to a motor vehicle with a swiveling screen that can be used for multiple purposes.

[0003] As new vehicle passenger compartment designs evolve, screens and lighting effects are becoming increasingly important.

[0004] It is therefore an object of the present invention to create a motor vehicle with a novel screen. This object is achieved by a motor vehicle according to claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

[0005] According to one embodiment of the invention, a motor vehicle is equipped with a dashboard; a screen which is pivotably mounted on the dashboard; and a projection display surface which is arranged below the screen pointing towards a vehicle passenger compartment, wherein the screen is pivotable at least between a usable position and a projection position, wherein a screen display area of ​​the screen in the usable position is directly usable as a screen display for vehicle occupants, and wherein the screen display area in the projection position points towards the projection display surface, so that representations and / or light effects can be displayed at least on the projection display surface by means of the screen display area.The advantage of this embodiment is that the screen is used multifunctionally, namely in a usage position in its actual function as a display screen for the direct presentation of entertainment media (e.g. films) or for the input of user instructions, e.g. in the form of a touch screen, as well as in its projection position as a light source or as a projector for illuminating a projection display surface in order to project images and / or light effects onto the projection display surface, thus creating an appealing lighting design in the vehicle passenger compartment.

[0006] The term "directly usable as a screen display" means that at least one passenger in the front row of the vehicle (properly seated in a vehicle seat) can look directly at the screen display to view display content, such as a film, entertainment content or the like.

[0007] In particular, the screen display cannot be used directly as a screen display in projection mode. Specifically, this means that the screen display area faces downwards, so that (properly seated) vehicle occupants cannot look directly at the screen display area, but rather it is hidden from them.

[0008] In particular, the screen is adapted such that when swiveling between the operating position and the projection position, it is swivelled by at least 60°, specifically such that, starting from the operating position to the projection position, a lower edge of the screen, relative to a longitudinal axis of the vehicle, is moved towards the front, and, starting from the projection position to the operating position, a lower edge of the screen, relative to a longitudinal axis of the vehicle, is moved backward. According to a further embodiment of the invention, in the projection position, a plane comprising an edge of the projection display surface facing the screen and an edge of the projection display surface facing away from the screen, forms an angle between 30° and 80° with the screen display surface on the side facing a vehicle passenger compartment.This provides an advantageous angle for achieving the desired projection image, so that on the one hand the screen display area is not directly visible to the (properly seated) vehicle occupant and on the other hand the vehicle occupants look at the projection display area from a comfortable viewing angle.

[0009] In particular, it is advantageous if the angle between a line of sight (from the eyes of a vehicle occupant to the projection display surface) and the projection display surface in the projection position is less than 90° in order to avoid a perpendicular viewing angle to the projection display surface.

[0010] It is also advantageous if, in the projection position, the screen display area and the projection display area are aligned to each other in such a way that a projection line (along which a screen display point is projected onto a point of the projection display area) and the line of sight to this point form an angle to which an angle normal of the projection display area forms the angle bisector.

[0011] According to a further embodiment of the invention, the screen display surface, in its operating position, forms an angle of 0° to 50° with a vehicle's vertical axis on the upward-facing side. This provides a comfortable viewing angle for the vehicle occupants. According to a further embodiment of the invention, in its projection position, the screen display surface forms an angle of -10° to 30° with a vehicle's longitudinal axis on the side facing the passenger compartment.

[0012] According to a further embodiment of the invention, the screen display surface, in the projection position, forms a first display area and a second display area. Furthermore, an edge of the projection display surface facing the screen is arranged closer to a transition between the first and second display areas than to a top or bottom edge of the screen. The first display area is also configured to project content onto the projection display surface, and the second display area is configured to project content into a background space located behind the projection display surface from the perspective of a vehicle occupant (properly seated in a vehicle seat) looking at the projection display surface.This has the advantage that, for example, objects can be displayed on the projection surface using the first display area, while the second display area allows for lighting effects in the form of backlighting (so-called ambient light) of the projection surface. In this way, the first and second display areas fulfill different functions in projection mode. In particular, the first and second display areas are only active in projection mode and not in normal use mode.

[0013] According to a further embodiment of the invention, the transition is spaced at least 1 cm away from the lower edge of the screen, which, in the projection position, is located furthest forward relative to a vehicle's longitudinal axis. In particular, the transition is an imaginary dividing line between the first and second display areas. The first and second display areas are, in particular, the same contiguous screen display area, one sub-area (first display area) of which displays different content than the other sub-area (second display area).

[0014] According to a further embodiment of the invention, the projection display surface can be pivoted and / or bent away from the screen during a swiveling movement of the screen. This creates a clearance so that the screen can be swiveled without collision. As soon as the screen has left a potential collision area or after completion of the swiveling movement, the projection display surface is returned to its initial position.

[0015] Alternatively or additionally, according to another embodiment, during a swiveling movement of the screen, the screen can be guided along a path curve via a kinematic mechanism and extended and retracted in such a way that a collision with the projection display surface is avoided.

[0016] According to a further embodiment of the invention, the screen in the projection position protrudes no more than 1 cm from an adjacent area of ​​the dashboard.

[0017] According to a further embodiment of the invention, the projection position corresponds to a fully swiveled and stowed position of the screen and the operating position to a fully swiveled position of the screen.

[0018] A preferred embodiment of the present invention is described below with reference to the accompanying drawings. These drawings depict the following: Figure 1 shows a motor vehicle according to an embodiment of the present invention, and

[0019] Figure 2 schematically shows a screen of the motor vehicle according to the embodiment of the present invention.

[0020] Figure 1 shows a motor vehicle 1, in particular a passenger car, according to an embodiment of the invention. A coordinate system shows a longitudinal axis x, a transverse axis y, and a vertical axis z, all of which are perpendicular to each other. The motor vehicle 1 has a passenger compartment 2 in which vehicle seats 3 are arranged and at the front end of which a dashboard 4 (see Fig. 2) is arranged.

[0021] Figure 2 shows the dashboard 4 of the motor vehicle 1, which extends, for example, across the entire width of the passenger compartment 2 (viewed along the vehicle's transverse axis y). A screen 5 is pivotably mounted on the dashboard 4. More precisely, the screen 5 can be pivoted between a user position 5a and a projection position 5b. This pivoting can be achieved, for example, about a pivot axis, a four-bar linkage, or the like, and can be carried out, in particular, by an electric motor. In the simplest case, manual operation would also be conceivable. In Figure 2, the screen 5 is shown in both positions 5a and 5b, and it is the same screen 5 that is depicted in different positions in the same figure.

[0022] In operating position 5a, a screen display surface 6 faces at least one vehicle seat 3, so that at least one vehicle occupant properly and upright seated in the vehicle seat 3 can look directly at the screen display surface 6 to view the displayed content, e.g., films and entertainment content, and / or to make inputs, particularly via touchscreen functionality. That is, in operating position 5a, this vehicle occupant can look at the screen display surface 6 in a straight line of sight. In this operating position 5a, the screen display surface 6 forms an angle α with respect to the vehicle's vertical axis z of 0° to 50°, so that in the range greater than 0° up to 50°, the upper edge of the screen 7 is positioned further away from the vehicle's longitudinal axis x than the lower edge of the screen 8. Operating position 5a represents a maximum swiveled-out state of the screen 5.

[0023] In projection position 5b, the screen display area 6 points downwards, so that properly seated, upright vehicle occupants cannot look directly at the screen display area 6. That is, in projection position 5b, these vehicle occupants cannot see the screen display area 6 in a straight line of sight; it remains hidden from them. In this projection position 5b, the screen display area 6 forms an angle β with respect to the vehicle's longitudinal axis x of -10° to 30°, such that in the range greater than 0° up to 30°, the upper edge of the screen 7, relative to the vehicle's vertical axis z, is positioned higher than the lower edge of the screen 8, and in the range less than 0° up to -10°, the upper edge of the screen 7 is positioned lower than the lower edge of the screen 8. Projection position 5b represents a maximum swiveled-out state of the screen 5.

[0024] Below the screen 5, relative to the vehicle's vertical axis z, a projection display surface 9 is arranged. The projection display surface 9 is a display surface for projected display content and is formed in (if covered with transparent material) or on a projection display 10. The projection display 10 can be a flat or curved (thin-walled) plate-shaped element or panel, one side of which is provided with the projection display surface 9. Furthermore, the projection display 10 itself can be opaque or semi-transparent. It can be made of metal, glass, and / or plastic. For example, the projection display 10 could simply be a mirror. Preferably, however, the projection surface 9 has a lower reflectance than a mirror.The projection display surface 9 can be designed not only as a flat surface but also with a 2.5D or 3D shape, for example, to create a lateral transition or to influence the size and position of the image. The projection display 10 is normally in a normal position 9c. During a pivoting operation of the screen 5, the projection display 10, in particular its edge facing the screen 5, can be pivoted downwards (i.e., away from the screen 5) and / or bent. Specifically, the projection display 10 is only bent / pivoted downwards during the pivoting operation and is otherwise in its normal position 9c. In Fig. 2, the downwardly pivoted and / or bent position is shown with reference numeral 9d.2 is therefore the projection display surface 9 / the projection display 10 shown in both positions 9c, 9d, where it is the same projection display surface 9 / projection display 10 and is shown in different positions in the same figure.

[0025] Alternatively or additionally, during a swiveling movement of the screen 5, the screen 5 can be guided along a trajectory curve via a kinematic mechanism and extended and retracted in such a way that a collision with the projection display surface 9 is avoided.

[0026] In its normal position 9c, the projection display surface 9 faces at least one vehicle seat 3, so that at least one vehicle occupant properly seated upright in vehicle seat 3 can look directly at the projection display surface 9 to view the displayed content. That is, in normal position 9c, this vehicle occupant can see the projection display surface 9 with a straight line of sight. When the screen 5 is in projection position 5b and the projection display surface 9 is in normal position 9c, a plane (one line of this plane is shown as a dashed line 11), which includes an edge of the projection display surface 9 facing the screen and an edge of the projection display surface 9 facing away from the screen, forms an angle y between 30° and 80° with the screen display surface 6 on the side facing a vehicle passenger compartment 2.

[0027] In its normal position 9c, the projection display surface 9 can be arranged such that an edge of the projection display surface 9 facing the screen is located near the lower edge 8 of the screen (this embodiment is not shown in Fig. 2). In this way, screen content emitted from the entire screen display surface 6 is projected onto the projection display surface 9 and produces a corresponding mirror image on it.

[0028] However, Fig. 2 shows a different arrangement of the projection display area 9. More precisely, in projection position 5b, the screen display area 6 has a first display area 6a and a second display area 6b. As shown in Fig. 2, an edge of the projection display area 9 facing the screen 5 is located closer to a transition 12 between the first and second display areas 6a and 6b than to the top edge 7 or the bottom edge 8 of the screen. The first and second display areas 6a and 6b are both sections of the same continuous screen display area 6. In projection position 5b, the first display area 6a, which extends from the top edge 7 to the transition 12, displays different content than the second display area 6b, which extends from the transition 12 to the bottom edge 8 of the screen.The transition 12 is in particular an imaginary dividing line on the screen display area 6, which runs parallel to the top edge of the screen 7 and the bottom edge of the screen 8.

[0029] Furthermore, a background space 11 is provided, which, from the perspective of a vehicle occupant looking at the projection display 9, is located behind the projection display 9, i.e., in front of the projection display 9 with respect to the vehicle's longitudinal axis x. The background space 11 is bordered to the vehicle occupant compartment 3 by the projection display 10, upwards by the screen display 6 (in particular its second display area 6b), and downwards (with respect to the vehicle's longitudinal axis x) by a curved wall 13 that bulges forwards, and downwards by a flat wall 14. The walls 13 and 14 can have reflective properties on their inward-facing surfaces, i.e., those facing the screen display 6. The walls 13 and 14 can also have a different shape, so that, for example, a rectangular background space 11 is formed.

[0030] The first display area 6a is functionally assigned to the projection display surface 9, and the second display area 6b is functionally assigned to the background space 11. More precisely, the first display area 6a is configured to project content onto the projection display surface 6, and the second display area 6b is configured to project content into the background space 11. In this way, objects can be displayed on the projection display surface 9 via the first display area 6a. Depending on the properties of the projection display surface 9, these objects can be mirror images of the first display area 6a, or 3D effects can be created so that the object is displayed as a hologram. Optionally, the second display area 6b can also be used to create lighting effects in the form of ambient light for the projection display surface 9. This effect can optionally be enhanced by additional light sources positioned next to or adjacent to the first display area 6a.are located outside the screen display area 6.

[0031] While the invention has been illustrated and described in detail in the drawings and the preceding description, this illustration and description is to be understood as exemplary and not as limiting, and it is not intended to limit the invention to the disclosed embodiment. The mere fact that certain features are mentioned in various dependent claims is not intended to imply that a combination of these features could not also be advantageously used.
