Description

Technical Field

[0001] The present disclosure relates to a display device for arrangement on the inside of a roof of a motor vehicle and / or a motor vehicle having the display device. Background Art

[0002] It is known to install a display device for the optical display of images and / or videos in motor vehicles, for example passenger cars, on the inside of the vehicle roof in association with a seat.

[0003] Known display devices are assigned to viewers in the rear seats and are accordingly installed there. Although some have proposed adjustment mechanisms for adjusting the viewing distance, these do not allow for sufficiently flexible operation considering other vehicle interior components. Furthermore, the overall available installation space for arranging the display devices is often underutilized.

[0004] Document DE 10 2016 225 745 A1 describes a screen which is arranged and fastened in the vehicle interior in the region of the roof interior, the screen extending continuously over at least half, preferably at least two thirds, in particular substantially the entire width of the roof interior.

[0005] Document DE 10 2019 13 19 25 A1 describes a display device for a vehicle interior. The display unit is designed for optically displaying information and, for this purpose, comprises a display element. The display unit is arranged or can be arranged behind the front seats in the longitudinal direction of the vehicle, preferably on the vehicle's roof. A movement unit is designed to pivot the display unit, particularly by means of the display element, outwardly from the vehicle's roof in the longitudinal direction, particularly controllably between different operating positions and / or to maintain it in a given operating position. The control unit is designed to control the movement unit such that the display unit and the display element are arranged or spaced apart from elements of the front seats at a predetermined first distance or at a first distance.

[0006] Document DE102020101719A1 describes a display device for a vehicle interior. The display unit is designed to optically display information and is arranged or can be arranged on the vehicle's roof ceiling. The movement unit is designed to controllably (open-loop controllable) and / or adjustably (closed-loop controllable) move the display unit between different usage positions along the longitudinal extension of the vehicle and / or to maintain it in a given usage position. The first usage position comprises a first position for one or more front seats in the longitudinal extension direction, and the second usage position comprises a second position for one or more rear seats in the longitudinal extension direction or for one or more luggage compartments for the display unit.

[0007] Furthermore, display devices are known that each comprise a screen and a mirrored disk, which together generate a virtual image in space. This allows for a sufficiently wide viewing distance between the user and the virtual image. To achieve this, such display devices must be positioned as far in front of the user as possible in the vehicle. In rear-seat configurations of motor vehicles, the front seats limit the installation space forward, so the mirrored disk must maintain a sufficient distance from the front seats. Therefore, it is recommended that the display system be adjustable and that the distance to the corresponding seat adjustment be kept as close as possible in front.

[0008] Until now, it has only been known to mount such a display device on a rail system and to have the entire display device track the front seat. If the front seat is adjusted forward or backward by a dimension X, the entire display device is also adjusted by the same dimension X, whereby the virtual image is also moved in space by the dimension X.

[0009] For example, the viewing distance between the eyes of the occupant and the virtual image has been increased by, for example, more than 150 mm compared to a conventional display device that is essentially composed only of a screen. This makes viewing the screen content significantly more comfortable.

[0010] This display device must be aligned for the largest front passenger or for the front seat that moves backward significantly.At the smaller front passenger place that accordingly makes the front seat move further forward, the whole display system also can move forward.

[0011] A disadvantage is that the entire display device in the motor vehicle must be moved. This also includes one or more screens that must be supplied with power or data via electrical lines. Furthermore, known display devices are relatively heavy (typically several kilograms) and therefore require complex mechanical devices to achieve their movement.

[0012] Furthermore, this deterministic approach does not provide the maximum possible viewing distance. Instead, for every millimeter that the display device is moved forward, only approximately one millimeter of additional viewing distance is obtained. Summary of the Invention

[0013] Against the background of this prior art, the object of the present disclosure is to specify a device which is suitable for improving the prior art.

[0014] This object is achieved by the features of the independent claims. The independent claims and the dependent claims each contain optional developments of the present disclosure.

[0015] Therefore, this object is achieved by a display device for arrangement on the inside of a roof of a motor vehicle. This display device can also be referred to as a combiner display device (or system), for example.

[0016] The display device comprises a screen arrangement comprising a first side for placement and / or contact against the inside of a vehicle roof (and / or a roof ceiling of a motor vehicle) and a second side opposite the first side and having a screen for displaying images.

[0017] The display device comprises a reflector arrangement for reflecting and projecting an image displayed via a screen. The reflector arrangement can also be referred to as a mirror disk and / or a combiner disk.

[0018] The display device comprises a motion device for moving the reflector device in translation relative to the screen device. The motion device may also be referred to as an adjustment mechanism of the reflector device.

[0019] The reflector device can be designed (and / or arranged) such that, in use (and, for example, in the installed state), the image displayed by the screen is visible to a user, for example, a vehicle occupant. The user can be located, for example, sitting, behind the reflector device and / or on the side of the screen device opposite the reflector device. The reflector device can be located, for example, in the field of view and / or the direction of sight of a user looking towards the reflector device, in use.

[0020] By reflecting and projecting the image displayed by the screen, a virtual image can be generated (or displayed).The image displayed by the screen can be reflected to the user's eyes by the reflector device to generate a virtual image that is located behind the reflector device for the user.

[0021] The virtual image can be derived from the relative positions of the screen device and the reflector device and the user's eye position. The face of the reflector device can be arranged at an angle of 45 degrees + / - 20 degrees, optionally + / - 10 degrees relative to the first side of the screen device, for example.

[0022] The (observation) distance of the user and the virtual image can be derived from the distance between the user and the reflector device and the distance between the reflector device and the screen device. In other words, as the distance between the reflector device and the screen device increases, the virtual image can be displayed farther and farther behind the reflector device for the user.

[0023] The display device may further comprise a stand on which the screen device and the movement device are mounted.

[0024] The reflector arrangement can be moved manually or automatically, for example mechanically, electrically, hydraulically and / or electro-hydraulically, by means of a movement device. The movement device can, for example, have at least one guide rail, at least one pivot arm and / or at least one telescopic arm, which can be or is mounted on the inside of the roof and extends, for example, in the width direction of the screen arrangement and / or in the longitudinal direction of the motor vehicle.

[0025] The above-described display device offers a number of advantages. In particular, it advantageously eliminates the need for the screen itself, its electrical connections, and the electronics integrated therein to be movably arranged. This allows the movable component, namely the reflector device, to be constructed more lightweight with the aid of the motion device, and the kinematic mechanism for moving the movable component of the display device can therefore also be designed for a lower weight. The reflector device may weigh, for example, 400 grams. When installed in a motor vehicle, the lower weight of the reflector device compared to the screen also offers advantages in the event of a head-on collision (in which case there is a possibility that a person sitting behind the reflector device will collide with the reflector device), as the reflector device has a lower mass.

[0026] Furthermore, with only the movement of the reflector device, a viewing distance can advantageously be achieved that increases by (almost) twice the movement travel (or adjustment travel). In an installation situation in which the display device is arranged behind a front seat and the space for the forward movement (or translational movement) of the reflector device is defined by the front seat, when the front seat is moved forward, for example, the viewing distance increases by (almost) twice the movement travel (or adjustment travel) when the reflector device is tracked, because the resulting viewing distance consists of the distance from the user's eye to the reflector device (which distance can approximately increase as the front seat moves forward) and the distance from the virtual image behind the reflector device (which distance increases accordingly as the distance between the screen and the forward-moving reflector device increases).

[0027] Next, feasible expansion solutions for the above-mentioned display device are described in detail.

[0028] The screen arrangement can be designed to be arranged fixedly and / or immovably on or in the interior of the vehicle roof (and / or the roof ceiling of the motor vehicle).

[0029] The movement device can be designed to move the reflector device parallel to or obliquely downwards and / or upwards relative to the longitudinal direction of the motor vehicle between different use positions. The movement device can be designed to move the reflector device parallel to or obliquely downwards and / or upwards relative to the longitudinal direction of the motor vehicle between different use positions.

[0030] The movement device can also be designed to rotate the reflector device relative to the screen device. The rotational movement can include a pivoting movement about a pivot axis, which is oriented parallel to and offset from the second side of the screen device.

[0031] The movement device can be designed to rotate the reflector device so as to pivot the reflector device between a non-use position in which the reflector device is oriented parallel to the second side and / or the screen and / or covers the screen, and a plurality of use positions. In one of the plurality of use positions, the reflector device and the screen device can form an angle of less than 180°, optionally equal to or less than 90°.

[0032] The rotational movement can be coupled to the translational movement. The movement device can also be designed to automatically perform the rotational movement as a function of the translational movement.

[0033] The movement device can also be designed to perform a tilting movement of the reflector device about a tilting axis perpendicular to the pivot axis.

[0034] The display device can be designed to correct a tilt of an image reflected and projected by the reflector device by a tilting movement of the reflector device by means of the movement device and / or by a rotation of the image displayed by the screen.

[0035] The display device may further include a detection device.

[0036] The detection device can be designed to detect the eye position (and / or the viewing direction) of a user who, when the display device is in use (for example in the forward direction of travel of a motor vehicle), is located behind the display device.

[0037] The detection device can be designed to detect the distance between the reflector device and an object that is arranged in front of the display device during use (e.g., in the forward direction of travel of the motor vehicle). The object can be an element (e.g., a headrest) of the front seat (or at least one front seat), the driver's seat, and / or the front passenger seat of the motor vehicle.

[0038] The display device may further comprise a control device which is signal-connected to the detection device and is designed to control (or open-loop control and / or closed-loop control) a motion device for moving the reflector device according to the detected eye position of the user and / or the detected distance.

[0039] The control device can be designed to actuate the movement device for moving the reflector arrangement taking into account the detected distance, so that the reflector arrangement is arranged at a minimum distance from the object.

[0040] The control device can be designed to repeatedly and / or continuously check the distance between the reflector arrangement and the object and to track this distance in order to maintain a minimum distance.

[0041] The minimum distance may be, for example, a distance that ensures that even in the event of load changes in the front seat, for example movements of the front vehicle occupant and / or due to the elasticity of the front seat, no contact occurs between elements of the front seat, for example the head support, and the reflector arrangement.

[0042] The control device can be designed to actuate the movement device for moving the reflector device taking into account the detected eye position in such a way that the reflector device is arranged at a minimum eye distance from the user.

[0043] The control device can be designed to repeatedly and / or continuously check the eye position and to track it in order to maintain the minimum eye distance.

[0044] The detection device can have at least one sensor unit for detecting an eye position and / or a distance.

[0045] The reflector device can be formed from an inherently rigid plate. The reflector device can be formed from plastic (e.g., organic glass or fiber-reinforced plastic) or glass. Advantageously, the reflector device can be sufficiently rigid with respect to the image to be reflected to avoid distortion of the reflected image. Alternatively or additionally, the reflector device can have a reinforcement frame.

[0046] The reflector device can include a reflective layer that can be polarized according to the light emitted by the screen device. The reflective layer can be adapted to the properties of the screen device; for example, the light emitted by the screen device can be p-polarized or polarized using an additionally applied polarizer. Advantageously, the reflector device can be designed to reflect only the polarized light of the screen device, but not other components or objects in the interior of the vehicle.

[0047] The reflector device can be configured to be transparent or partially transparent. Advantageously, the transparency of the reflector device enables a forward perspective for a user sitting in front of the reflector device.

[0048] The outer shape of the reflector arrangement may be matched to the virtual image.The reflector arrangement may not be square or rectangular.

[0049] The content of the above description can be summarized in other words as a possible more specific design solution of the present disclosure as described below, wherein the following description should be interpreted as not limiting the present disclosure.

[0050] In the sense of the present disclosure, the one or more displays (or the screens of the screen arrangement) can be mounted in a fixed position in the vehicle, and only the mirror disk (or the reflector arrangement) can track the front seats in a suitable manner. This allows a leverage factor to be achieved in the gain in viewing distance. In theory, the viewing distance can be increased by twice as much as if the seats had been adjusted forward. Therefore, the system can be designed according to the largest seat percentile to be considered in the first row of seats. This can determine the rearmost adjustment position of the mirror disk, which in turn determines the orientation of the one or more displays. If the front seats are moved forward, only the mirror disk can track.

[0051] For example, the mirror plate can be moved in a translational manner in a guide. Since the beam path is slightly altered during this process, the observer can adjust the angle of the mirror plate accordingly. This can be done manually. It is conceivable to couple the necessary rotation with the translation and automatically track it. This can also be done electrically, if desired. Sensors can also detect the observer's (or user's) eye position and automatically establish the optimal orientation of the mirror plate in the vehicle based on the position of the front seats. For this purpose, coordinates can be exchanged between the front seats and the display system, as disclosed, for example, in DE 10 2019 13 19 25 A1.

[0052] In other words: the display can always be kept fixedly mounted at the same position in the vehicle roof. Only the combiner disk (or mirror disk and / or reflector device), which weighs only approximately 400 g, can be moved, so that a relatively simple movement mechanism is sufficient.

[0053] If several display devices are installed, each of the combiner panels can be individually adapted to the position of the front seats. If the entire system is moved, the rearmost seat must always be used as a reference.

[0054] An (almost) twice as great increase in the viewing distance can be achieved with the movement of the combiner disc, since the achieved viewing distance consists of two components: the distance from the eye to the combiner disc, which increases approximately as the front seat is moved forward, and the distance of the virtual image behind the combiner disc, which increases accordingly with the distance between the display and the combiner disc moved forward.

[0055] Furthermore, as the distance changes and the eye position in the rear seat area varies, the virtual image can tilt relative to the normal direction of the viewing beam. This can be corrected, for example, by moving the right and left sides of the combiner disk forward to varying degrees or by slightly rotating the image on the screen so that it is upright again in the virtual image.

[0056] Furthermore, a motor vehicle including the above-mentioned display device is provided.

[0057] The motor vehicle can be a passenger car, in particular a car, or a commercial vehicle, for example a truck.

[0058] The motor vehicle may include a front seat (or at least one front seat), a driver's seat and / or a co-pilot seat. The front seat, the driver's seat and / or the co-pilot seat may be longitudinally adjustable.

[0059] The motor vehicle may include a rear seat. The display device may be assigned to the rear seat and / or the reflector arrangement may be designed (and / or arranged) such that, in the case of use, the image displayed by the screen is visible to a vehicle occupant located in, for example, a seated vehicle in the rear seat.

[0060] The display device can be arranged on the inside of the roof in the rear seat area of the motor vehicle.

[0061] The display device can be arranged behind the front seats, the driver's seat and / or the front passenger seat in the longitudinal direction and / or in the forward driving direction of the motor vehicle.

[0062] The movement device can be designed to move the reflector device in a translational manner, so that the reflector device moves forward in the longitudinal direction of the motor vehicle and / or in the forward driving direction away from the screen device, and moves backward in the longitudinal direction of the motor vehicle and / or in the rearward driving direction toward the screen device.

[0063] The outer edge of the screen device may extend parallel to or perpendicular to the longitudinal direction (and / or transverse direction) of the motor vehicle.The first side and / or the second side of the screen device may extend parallel to the inner side of the roof.

[0064] The longitudinal direction of the screen device and / or the reflector device can extend in the transverse direction of the motor vehicle.The length of the screen device and / or the reflector device can correspond to at least half the width of the motor vehicle.

[0065] It is also conceivable that the motor vehicle includes multiple display devices described above, for example, a first display device and a second display device. The first display device may be arranged behind the driver's seat, and the second display device may be arranged behind the passenger seat. The first display device and the second display device may be arranged side by side, for example, parallel to each other, or at an angle to each other.

[0066] The above description with reference to the display device also applies analogously to the motor vehicle, and vice versa. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] Next, refer to Figure 1A 、 1B2 and 2 describe alternative embodiments compared to known motor vehicles or known display devices.

[0068] Figure 1A 、 1B A known motor vehicle with a display device is schematically shown, and

[0069] Figure 2 A motor vehicle having a display device according to the present disclosure is schematically shown. DETAILED DESCRIPTION

[0070] exist Figure 1A A known vehicle 110 according to the prior art is shown only schematically in FIG.

[0071] The motor vehicle 110 includes a display device 101 which is mounted on a bracket on the roof inner side 111A of a vehicle roof 111 .

[0072] The display device 101 comprises a screen device 102 oriented parallel to the inner side 111A of the vehicle roof, and a pivotably mounted reflector device 103 for reflecting and projecting an image displayed on the screen of the screen device 102. To simplify the illustration, only one plane of the reflector device 103 is shown, wherein in this embodiment the reflector device is fixed to the screen device 102 or to a support of the display device 101.

[0073] The display device 101 is arranged behind the front row of seats including the front seat 112. A user 130 who looks at the reflector arrangement 103 when the display device 101 is in use is located in the rear row of seats and is, for example, sitting on the rear seat.

[0074] The reflector device 103 is designed or arranged to make the image displayed by the screen visible to the user 130 in this use case. The virtual image 104 is generated (or displayed) by reflecting and projecting the image displayed by the screen of the screen device 102, wherein the image is reflected by the reflector device 103 to the eyes of the user 130 to generate the virtual image 104 that is located behind the reflector device 103 for the user 130.

[0075] The viewing distance 131 between the user 131 and the virtual image 104 results from the distance between the user 131 and the reflector device 103 and the distance between the reflector device 103 and the screen device 102. In other words, as the distance between the reflector device 103 and the screen device 102 increases, the virtual image 104 can be displayed farther and farther behind the reflector device 103 for the user 131.

[0076] When the reflector device 103 is pivoted, a minimum distance 105 is maintained between the head support 112A of the front seat 112 and the reflector device 103 due to the flexibility of the front seat 112, for example its length adjustability. Since the front seat 112 in the motor vehicle 110 is longitudinally adjustable, it is also useful to make the display device adjustable in order to provide the user 131 with the maximum possible viewing distance at any time.

[0077] For this purpose, it is known that the entire display device 101 can be displaced in the longitudinal direction of the motor vehicle 111. For this purpose, the entire display device 101 can be guided in at least one guide rail, for example.

[0078] Figure 1B A known vehicle 110 is schematically shown with a display device 101 in two different adjustment positions A and B. Display device 101 is shown for each of the adjustment positions and is emphasized by a circle, display device 101 and the circle being shown in continuous lines in adjustment position A and in dashed lines in adjustment position B.

[0079] If front seat 112 is adjusted forward, for example, by an adjustment distance X, display device 101 can be adjusted forward from adjustment position A to adjustment position B by the same amount, i.e., the same adjustment distance X. This movement increases viewing distance 131A by the adjustment distance X, resulting in viewing distance 131B. If front seat 112 is adjusted forward, for example, by 50 mm, the viewing distance is also increased by 50 mm.

[0080] exist Figure 2 A vehicle 10 according to an embodiment of the present disclosure is shown only schematically in FIG.

[0081] The motor vehicle 10 comprises a display device 1 which is arranged on a roof inner side 11A of a vehicle roof 11 , for example in the rear seat area of the motor vehicle 10 .

[0082] Display device 1 includes screen device 2, which includes a first side 2A for being arranged and / or abutted against inner side 11A of a vehicle roof, and a second side 2B opposite to first side 2A and having a screen for displaying an image. In contrast to screen device 102 of known display device 101, screen device 2 is fixedly and / or immovably arranged (or mounted) on or in inner side 11A of the vehicle roof.

[0083] The display device 1 further comprises a reflector device 3 for reflecting and projecting an image displayed through the screen, and a movement device 5 for moving the reflector device 3 in translation relative to the screen device 2 .

[0084] The display device 1 is arranged behind a front row of seats including the front seat 12. A user 30 who looks at the reflector arrangement 3 when the display device 1 is in use is located in the rear row of seats and is, for example, sitting on the rear seat.

[0085] Similar to the known display device 101 with the reflector device 103 , the reflector device 3 is designed or arranged to make the image displayed by the screen visible to the user 30 in the case of use, wherein a virtual image 4 is generated (or displayed).

[0086] In order to enable the display device 1 to track the longitudinally adjustable front seat 12 and thus to provide the user 30 with the maximum possible viewing distance at any time, the reflector device 3 can be moved, for example, toward or away from the front seat 12 by means of the movement device 5 independently of the screen device 2. In this case, a minimum distance between the reflector device 3 and the head support 12A should be maintained.

[0087] Two different adjustment positions A and B of the reflector device 3 and the movement device 5 are shown. The reflector device 3 and the movement device 5 are shown for each of the adjustment positions and are emphasized by circles, wherein the reflector device 3, the movement device 5 and the circles are shown in adjustment position A with a solid line and in adjustment position B with a dashed line.

[0088] If the front seat 12 is adjusted forward, for example, by an adjustment travel X, the reflector arrangement 3 can be adjusted forward from the adjustment position A to the adjustment position B by the same amount, i.e., the same adjustment travel X. This movement increases the viewing distance 31A by (almost) twice the adjustment travel X, resulting in a viewing distance 31B. If the front seat 12 is adjusted forward, for example, by 50 mm, the viewing distance increases by a factor of 2, i.e., by, for example, 50 mm.

[0089] In the schematic diagram, the movement device 5 is also shown schematically and greatly simplified, in addition to other components. The movement device 5 can be fixed to the screen device 2 and / or to a bracket of the display device 1. In addition, the movement device 5 can have, for example, at least one guide rail mounted on the inner side 11A of the roof and extending in the longitudinal direction of the motor vehicle 10, at least one pivot arm, and / or at least one telescopic arm.

[0090] Furthermore, the movement device 5 can be designed to move the reflector device 3 not only between different operating positions in the longitudinal direction of the motor vehicle 10, but also to move it downwards and / or upwards, for example, obliquely relative to the width direction of the screen device 2 or the longitudinal direction of the motor vehicle 10. The displacement of the reflector device in terms of (vehicle) height is not critical.

[0091] Furthermore, the movement device 5 can be designed to perform a rotational movement of the reflector device 3 relative to the screen device 2 , wherein the rotational movement can include a pivoting about a pivot axis which is oriented parallel and offset to the second side 2B of the screen device 2 .

[0092] The rotational movement can be coupled to the translational movement and / or the movement device 5 can also be designed to automatically carry out the rotational movement as a function of the translational movement.

[0093] The movement device 5 can also be designed to tilt the reflector device 3 around a tilt axis perpendicular to the pivot axis. If the reflector device 3 is tiltable, the display device 1 can also be designed to correct the tilt of the image reflected and projected by the reflector device 3, that is, the virtual image 4, by tilting the reflector device 3 with the help of the movement device 5 and / or by rotating the image displayed on the screen.

[0094] The display device 1 may further include a detection device and a control device. The detection device may be designed to detect the eye position of a user who, when the display device 1 is in use, is located behind the display device 1 and / or the distance between the reflector device 3 and an object that is located in front of the display device 1. The control device may be connected to the detection device for signaling purposes and may be designed to control the movement device 5 for moving the reflector device 3 based on the detected eye position of the user and / or the detected distance, for example, to maintain a minimum distance between the reflector device 3 and the head support 12A.
