Description

Technical Field

[0001] The invention relates to a device for a vehicle roof having a display assembly. The invention also relates to a vehicle roof for a motor vehicle having such a device. Background Art

[0002] Some motor vehicles have screen assemblies which can provide entertainment programs as desired and contribute to increased comfort in the motor vehicle. If necessary, such screen assemblies are provided with a kinematic design which enables the screen assembly to be folded in and out when necessary. The challenge here is to achieve a space-saving and cost-effective arrangement of such entertainment electronics and to contribute to the comfort of the motor vehicle. Summary of the invention

[0003] The object underlying the present invention is to provide a device for a vehicle roof having a display arrangement which can contribute to increased comfort in the motor vehicle.

[0004] This object is achieved by the features of the independent claim. Advantageous developments are given in the dependent claims.

[0005] A device according to the invention for a vehicle roof comprises a guide rail, which is provided for coupling with a roof body of a vehicle roof. The device also comprises a display assembly, which comprises a transparent display and at least one display attachment, which establishes a mechanical and electrical attachment. The device also comprises a lever mechanism, which is configured to swivel the display assembly outward and inward and / or move it, and which is movably coupled to the guide rail on the one hand and movably coupled to the display assembly on the other hand by means of the display attachment, so that when the lever mechanism is actuated by means of a drive unit, the display assembly can be swung open and swung inward and / or moved.

[0006] In the context of the present invention, it is recognized that in conventional designs, screens installed in motor vehicles are not transparent and usually have relatively complex and space-consuming attachments. They are hidden, for example, in the headrests or behind the vehicle roof in order to cover or hide the necessary electronic components behind the screen. The attachment to the vehicle peripherals is also usually implemented in the area of ​​the image-generating surface or behind it, because the screen is not transparent and the associated mechanical and electrical contacts are not visible in any case. Therefore, in conventional designs, it is not possible for the observer to see what is happening behind the screen. Although such screens provide a comfortable entertainment possibility, such screens reduce the viewing area of ​​the vehicle passengers for whom the entertainment system is provided. In particular, in combination with a glass roof or a panoramic roof, the screen reduces the outward field of view when it is folded in the non-use position or in the parking position.

[0007] Furthermore, depending on the vehicle structure (e.g. the position of the windshield and cockpit) and the screen size, such screens can obstruct the view to the surroundings in the folded-out position of use or in the cinema position. This can lead to the onset of so-called "motion sickness", especially when watching moving images or films while driving. Motion sickness describes a type of travel sickness and is caused by a contradiction in perception when the eyes perceive something different from the balance system in the inner ear.

[0008] The described device and the transparent display can counteract the previously described adverse effects and contribute to the particular comfort of the motor vehicle. By integrating the transparent display into the vehicle roof environment, the passengers can perceive the surroundings through the display both upwards in the parking position and forwards in the use position.

[0009] In connection with the present description, terms such as "upper", "lower", "front", "rear", "upper side", "lower side" as well as "horizontal" and "vertical" refer to the direction or orientation of a motor vehicle with a vehicle roof and a device with a display assembly arranged thereon, according to the vehicle being put into use. The usual direction of travel is oriented forward, while the rear of the vehicle is arranged at the rear. The longitudinal axis of the vehicle can be regarded as a line between the rear of the vehicle and the front of the vehicle.

[0010] According to a development of the device, the display attachment comprises a lateral attachment, which establishes a mechanical and / or electrical coupling of the transparent display to the lever mechanism on the side facing the guide rail. In particular, such lateral attachments can be provided on the vehicle roof and on the opposite sides of the display, respectively, which are coupled to the corresponding lever mechanism and the corresponding guide rail. If the transparent display is designed, for example, as a relatively large display, for example as a transparent panoramic display, then, in addition to the display itself, the described components of the device are especially present in duplicate and are designed and / or arranged mirror-symmetrically with respect to the central vehicle longitudinal axis.

[0011] By means of the described lateral attachments, the upper and lower edges of the transparent display can be kept free of contact and an overall impression that is particularly aesthetically appealing can be achieved. Due to its transparency, the transparent display allows a see-through view into the area behind the display (both during operation and especially in the non-operating state). This contributes to an increased level of comfort in the motor vehicle.

[0012] For example, the transparent display is implemented as an OLED display and has no backlight. Power supply and control as well as mechanical retention can be provided by lateral attachments or display attachments and are therefore only displaced into the outer area. For example, the OLED display comprises only one OLED panel introduced between two glass plates and can have a transparency of, for example, 20% to 50%. Alternatively, other transparency values ​​can also be provided depending on the available technology. Transparency here refers in particular to the spectral range that is visually visible to humans and can include individual wavelengths and / or wavelength ranges in the visually visible spectrum.

[0013] According to another development of the device, the display attachment comprises a bridge attachment, which establishes the coupling of the transparent display screen with the lever mechanism on at least one side, which faces the vehicle roof when the display screen assembly is folded out on the vehicle roof and can be put into use. The side described represents the upper side or upper edge of the display screen, which is arranged at the top in the folded-out state, while the lower side or lower edge of the display screen is oriented in the direction of the vehicle interior and arranged at the bottom in the folded-out state. In the state where the display screen is folded in or swung inwards, the upper edge and the lower edge are essentially at a height, so that the display screen is arranged, for example, mainly parallel to the vehicle roof in a horizontal plane. For example, the bridge attachment is an elongated transverse element, which extends from the lever mechanism on the left vehicle roof side to the lever mechanism on the right vehicle roof side.

[0014] According to another embodiment of the device, the display screen attachment comprises a frame attachment, which establishes a circumferential coupling of the transparent display screen on at least three sides of the display screen, two of which are mutually opposite. The frame attachment can form an open frame, which extends, for example, on the upper edge and side edges of the display screen, so that the lower edge of the display screen remains free. Alternatively, the frame connection can establish a completely circumferential coupling on all sides of the display screen, so that it forms a self-contained frame.

[0015] Thus, the transparent display screen can be integrated by means of a slender display screen attachment on the lever mechanism and / or a further component on the vehicle roof. The display screen attachment preferably holds the transparent display screen only in a minimal edge region and hardly obstructs or reduces the view through the transparent surface that generates the image. The display screen attachment can be provided in the form of a left / right retaining element in a materially locked (e.g. glued), force-locked (e.g. clamped and / or screwed) and / or form-locked manner.

[0016] According to another development of the device, the corresponding display attachment is transparently constructed. In particular, the transparency of the display attachment can be coordinated with the transparency of the display screen, so that the display attachment is almost invisible or at least is constructed in accordance with the transparent display screen. The display attachment can be completely transparent or partially transparent. Accordingly, the display assembly can be intentionally completely or partially opaque, for example, in order to cover or conceal certain positions or interfaces of electrical and / or mechanical attachments, and / or to meet customer-oriented design aspects.

[0017] The display attachment provides the energy and signaling supply as well as the mechanical connection of the transparent display. However, the electrical interface or interfaces do not have to coincide with the mechanical interface or interfaces, so that they can be provided in the form of a display attachment on one side of the display or can be distributed along one or more sides of the display. For example, the mechanical attachment by means of a lever mechanism preferably takes place on the outer side of the display facing the corresponding guide rail or rails.

[0018] Here, the lever mechanism can also establish an electrical attachment, for example, an electrical attachment on the side edge of the transparent display screen. Alternatively, a mechanical and / or electrical attachment can be provided on the upper edge of the transparent display screen. Even if the electrical attachment of the transparent display screen is provided separately from the mechanical attachment, the corresponding attachment is either directly or indirectly coupled to the lever mechanism and the guide rail.

[0019] According to another development of the device, the lever mechanism comprises a first and a second guide sliding contact and a first and a second swing lever. The swing levers are swingably coupled to each other and are swingably coupled to one of the guide sliding contacts, and the guide sliding contact is movably supported in a guide channel of the guide rail. By means of actuation of the lever mechanism, at least one of the guide sliding contacts can be driven and the swing lever can be swung and / or moved. In particular, the lever mechanism can be electrically actuated by means of a drive unit, the drive unit comprising an electric motor and a drive cable, the drive cable being coupled to the electric motor on the one hand and to the lever mechanism on the other hand.

[0020] The lever mechanism can be actuated by means of one or more drive units in order to adjust the display screen to the desired cinema position or parking position when necessary. The display screen is designed in particular as a rigid, transparent panoramic screen. Alternatively, the display screen can be implemented as a rollable OLED display screen that can be rolled up to a predefined diameter without impeding the electronics and functionality.

[0021] The vehicle roof according to the invention for a motor vehicle comprises a roof body and also an embodiment of the device described above with a display assembly, which is coupled to the roof body. The display assembly is coupled to a lever mechanism on the side facing the vehicle interior. With the aid of the device, a transparent display screen of the display assembly can be moved along the longitudinal axis under the vehicle roof and, for example, moved to the front or rear in the motor vehicle and folded out or folded in.

[0022] In particular, the vehicle roof comprises a roof element which is implemented, for example, as a roof system with one or more glass roofs or as a panoramic glass roof. Alternatively, the roof element can also form an opaque roof covering of the vehicle roof. The roof element can be arranged vertically adjustable or extendable and / or can be designed to be fixed to a roof body or movable relative to the roof body.

[0023] Since the vehicle roof comprises an embodiment of the device, the described features and properties of the device are also disclosed for the vehicle roof and vice versa.

[0024] The device and a corresponding vehicle roof can contribute to increased comfort of the motor vehicle and to better visibility through the vehicle roof. The display assembly is space-saving and can be arranged visually inconspicuously and comfortably adjustable due to its transparency and can also contribute to better visibility forward in the usual direction of travel through the inwardly swung display and through the vehicle roof or through the outwardly swung display.

[0025] The lever mechanism for swinging the display screen assembly open and swinging it inward and moving it can be constructed, for example, as follows: the lever mechanism is connected to the display screen by means of a display screen attachment. For example, the display screen attachment includes a retaining element. The lever mechanism includes a first and a second guide sliding contact, one of which can realize a drive slider, which causes the other guide sliding contact to move together at least in sections in a predetermined manner. The lever mechanism can include a first and a second swing rod, which is swingably coupled to one of the guide sliding contacts and can be moved by means of one or more drive units, especially electrically. The first guide sliding contact can have, for example, a guide section with a first driver. The first guide sliding contact can also be rigidly coupled to the second guide sliding contact by a swing rod at the beginning. The guide sliding contacts can be coupled to each other by means of a coupling element. Such a coupling element can have a rod element with a guide section, and the guide section includes a stop element, which interacts with the driver, so that the guide sliding contacts can be coupled to each other, for example, detachably. The movement of the first guide sliding contact can initiate the unlocking of the display screen assembly, so that the pivot lever can then be pivoted and can be pivoted downward and outward and the transparent display screen can be lowered.

[0026] The two guide sliding contacts are coupled to each other so that they can be moved relative to each other at least in sections and the spacing between the two guide sliding contacts can be adjusted in a predetermined manner, and the display screen assembly can be swung open and swung inward at a desired orientation angle by means of two swing rods in a predetermined manner. Here, the guide sliding contacts can be individually controlled or moved inside the guide rail, or can be coupled to each other at least in sections along the movement path by means of coupling elements. Thus, a translation and subsequent rotation of the display screen assembly along the longitudinal axis can be achieved. The guide sliding contacts are not necessarily completely contactless, but can be coupled to each other in particular in a sliding manner, thereby achieving a relative movement of the guide sliding contacts that guides each other.

[0027] The lever mechanism can be arranged such that the two guide sliding contacts have a first spacing from each other along the longitudinal axis in the first coupled state and a second spacing from each other in the second coupled state. For example, the second spacing is equal to or greater than zero and smaller than the first spacing. Accordingly, the spacing between the two guide sliding contacts can be reduced or increased in a controlled manner when the display assembly is swung open and swung inwards. Thus, the display assembly can be moved forward or backward under the vehicle roof and can be folded out and folded in and adjusted to a predetermined orientation angle by means of a predetermined movability of the swivel lever and the guide sliding contacts.

[0028] For example, the display assembly can be tilted in the direction of the vehicle interior to an orientation angle of 65°-85°. Here, such an orientation angle refers to the angle between the main extension plane of the display and a horizontal plane or a parking position in which the display is folded in. Alternatively, the orientation angle can refer to the angle enclosed between the main extension plane of the display and a vertical plane. Accordingly, an orientation angle of 5°-25° can be established. The adjustment of the orientation angle is particularly carried out continuously, but can also be set in predetermined steps. Thus, the outward or inward swinging of the display can also stop at an intermediate position of 30°, 40°, 50° or 60°, for example. In addition, the device can also be configured to achieve other angle ranges of the display for adjusting the display assembly.

[0029] The lever mechanism or at least one guide sliding contact is coupled to the motor, for example, by means of a drive cable. Only with such a drive unit can both the translational movement of the display screen or the display screen assembly and its rotational movement be achieved. The drive unit adjusts the spacing between the guide sliding contact and the desired orientation angle of the display screen assembly. Therefore, the display screen assembly can be swung inwardly and outwardly and moved in a controlled manner and reliably to construct a swing position or lifting position of the display screen assembly and adjust to the desired angular orientation. Alternatively, another drive unit can also be provided so that the guide sliding contact and / or the swing lever can be controlled independently of each other.

[0030] The lever mechanism can be realized cost-effectively and space-savingly, so that the installation space requirement in the vehicle interior can be kept small. In particular, the lever mechanism can be integrated in a vehicle roof or arranged on such a vehicle roof and can also achieve comfortable freedom of head movement in the vehicle interior. In this way, high-quality entertainment options in motor vehicles can be promoted.

[0031] Furthermore, the lever mechanism can include a locking unit, which is provided for fixing the position of the display assembly, for example, in the folded-in and / or folded-out state. In particular, the locking unit can be designed so that it interacts with the guide rail and / or the spring element and / or the stop element. For example, the guide rail includes a stop element, for example, in the form of an upwardly bent tongue, toward which the locking unit moves with the guide sliding contact and the locking or unlocking of the display assembly is formed by the stop element.

[0032] Alternatively or additionally, a spring element can be provided, which moves and twists in a predetermined manner toward the stop element when the drive slide is moved, and releases the locking of the display assembly. The spring element or another spring element can have, for example, a first spring arm and a second spring arm that are coupled to each other. The spring element can be used as an elastic compensation element to introduce coupled and elastic properties into the lever mechanism in a targeted manner, in order to achieve, for example, a smooth folding out of the display assembly. Accordingly, the spring element is coupled to the swing lever, for example, and the spring arm is embedded in it or hooked back, so that the spring element exerts an upward spring force on the swing lever, which reacts to the weight of the display assembly.

[0033] The two guide rail sliding contacts can have a corresponding plastic encapsulation which enables a sliding and low-resistance movement within the guide channel of the corresponding guide rail. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Elements of the same structure or function are marked with the same reference numerals throughout the drawings. For reasons of clarity, not all elements shown in all drawings may be marked with reference numerals. DETAILED DESCRIPTION

[0040] Figure 1A vehicle roof 1 of a motor vehicle is schematically shown in a perspective view, which comprises a roof element, a roof system or a roof 3, which closes a roof opening in the vehicle roof 1. For example, the roof 3 is a fixed glass element that is immovable relative to the vehicle roof 1. Alternatively, the roof 3 is movable relative to the vehicle roof 1 in order to selectively open and close the roof opening in the vehicle roof 1. Alternatively, the vehicle roof 1 may also not have a roof cover 3 and may realize a roof cladding without a groove, for example a foldable or foldable convertible top, which can be stored in the rear region of the motor vehicle. Furthermore, the vehicle roof 1 may also form a convertible top with the roof cover 3, in which the roof cover 3 is designed so that it can be folded together or folded.

[0041] A device 10 with a display assembly is arranged below the vehicle roof 1 and is coupled to the vehicle roof 1 or a roof body 2 of the vehicle roof 1. Figures 2 to 17 As explained, device 10 enables comfortable operation and orientation of the display assembly and also enables comfortable forward vision or upward vision through roof 3 of vehicle roof 1. Device 10 can be arranged on vehicle roof 1 in a space-saving manner and contributes to increased comfort of the motor vehicle.

[0042] In the context of the present description, terms such as "upper", "lower", "front", "rear", "upper side", "lower side", "lower side" as well as "horizontal" and "vertical" refer to the direction or orientation of a motor vehicle with a vehicle roof 1 that can be put into use, as in this Figure 1 As exemplified in the other figures. Accordingly, the horizontal plane is spanned by the drawn xy plane and is oriented perpendicularly to the drawn z direction, which is a vertical line. The longitudinal axis L coincides with the longitudinal axis of the vehicle, and the drawn arrow direction represents the usual forward direction of travel. The rear of the vehicle is arranged or constructed at the rear. Therefore, the display assembly is arranged below the vehicle roof 1 and / or is integrated therein and faces the vehicle interior of the motor vehicle.

[0043] Figures 2 to 6 One embodiment of an apparatus 10 is shown. Figures 2 to 5 The positions of transparent display screen 4 which can be configured with the aid of device 10 are shown in each case in a perspective view. Figure 6 A corresponding plan view or a view from above onto the inwardly pivoted display screen 4 is shown.

[0044] The device 10 comprises two guide rails 6, which are coupled to the roof body 2 on opposite sides of the vehicle roof 1. The device 10 also comprises a display assembly having a transparent display screen 4 and a display screen attachment 5, which establishes a mechanical and electrical attachment. The display screen attachment 5 can be configured as a lateral attachment 51 (see Figures 2 to 6 ), constructed as a bridge attachment 52 (see Figures 7 to 12 ) or constructed as a frame attachment 53 (see Figures 13 to 17 ), or includes such a lateral attachment 51, a bridge attachment 52 or a frame attachment 53.

[0045] The device 10 further comprises two lever mechanisms 15, which are coupled to the roof body 2 on opposite sides of the vehicle roof 1 and are provided for swinging the display assembly outward and inward and / or moving the display assembly. The lever mechanisms 15 are respectively coupled movably to the corresponding guide rails 6 on the one hand and are coupled movably to the display assembly on the other hand by means of the display attachment 5, 51, 52 and / or 53, so that when the lever mechanisms 15 are actuated by means of the drive unit, the display assembly can be swung open and swung inward and / or moved.

[0046] The lever mechanism 15 includes a first guide sliding contact 11 and a second guide sliding contact 12 and a first swing rod 13 and a second swing rod 14. The first swing rod 13 is rotatably coupled to the first guide sliding contact 11 and the second swing rod 14. The second swing rod 14 is rotatably coupled to the first swing rod 13 and the second guide sliding contact 12. The guide sliding contacts 11 and 12 are movably supported in the guide channels of the corresponding guide rails 6, so that the first guide sliding contact 11 is driven by means of the manipulation of the lever mechanism 15, for example, by means of a drive unit having a motor and a drive cable, and the swing rods 13 and 14 directly or indirectly coupled to the first guide sliding contact can be swung and / or moved.

[0047] according to Figures 2 to 6 , the display screen attachment 5 is implemented only as a lateral attachment 51, so that on the opposite side of the vehicle roof 1, the lateral attachment 51 respectively establishes the mechanical coupling and energy supply and electrical control of the transparent display screen 4. The lateral attachment 51 is constructed in sections on the corresponding outer lateral edges of the display screen 4 and is coupled to the swing levers 13, 14 of the lever mechanism 15 and faces the corresponding guide rails 6. The upper and lower edges of the transparent display screen 4 have no additional elements. The sections on the side edges of the display screen 4 can also remain free. Therefore, the transparent display screen 4 allows particularly comfortable perspective, not only in the operating state, but also especially in the parked or stationary state.

[0048] Figure 2 and 6 In each case, a transparent display screen 4 is shown in a completely swung-in or folded-in state, which allows a wide view through the roof panel 3 of the vehicle roof. Figure 3 The display screen 4 is shown in a partially pivoted open or exposed state. Figure 4 The display screen 4 is shown in the pivoted open or exposed state. Figure 5 The display screen 4 is shown in a swing-open or open state, in which the display screen is moved forward and is in contact with the display screen. Figure 4 In contrast, the display screen has a slightly differently set orientation angle within the vehicle interior. Preferably, the display screen 4 is stowed in its parking position substantially parallel to the vehicle roof 1 in the rear region.

[0049] Figures 7 to 12 Another embodiment of the device 10 is shown. Figures 7 to 11 The positions of the transparent display screen 4 are shown in each case in a perspective view, which positions can be configured with the aid of the device 10. Figure 7 It can be seen in FIG. 8 that the roof frame 7 can provide for the movability of the display screen 7 . Fig.12 A corresponding plan view or a view from above is shown of the inwardly pivoted display screen 4 .

[0050] Figure 8 and 12 In each case, a transparent display screen 4 is shown in the completely swung-in or folded-in state, which allows a wide view through the roof panel 3 of the vehicle roof. Fig. 9 The display screen 4 is shown in a partially pivoted open or exposed state. Fig.10 The display screen 4 is shown in the pivoted open or exposed state. Figure 7 and 11 The display screen 4 is shown in each case in a swung-open or open state, in which, among other things, the display screen is moved forward and is in contact with the display screen 4. Fig.10 In contrast, the display screen has a slightly differently set orientation angle within the vehicle interior.

[0051] According to Figures 7 to 12The display attachment 5 of the embodiment is realized in the form of a bridge attachment 52, which extends along the upper edge of the display screen 4 between the lever mechanisms 15 on the left and right sides. The bridge attachment 52 can be used in particular for power supply or control, and is coupled to the on-board power supply of a motor vehicle, for example. The same may also be applied to other embodiments of the display attachment 5. Alternatively or additionally, the electrical attachment can also be realized by the lateral attachment 51. Alternatively or additionally, the bridge attachment 52 can also realize a mechanical retaining element, which helps to stably and safely hold the display screen 4.

[0052] According to Figures 7 to 12 In the embodiment of the invention, in addition to the bridge attachment 52, two opposite side attachments 51 are shown, which can be regarded as part of the bridge attachment 52 or as separate additional attachment sections. Figures 2 to 6 and Figures 13 to 17 In particular, the lateral attachment elements 51 can be smaller, narrower and / or shorter than in other exemplary embodiments, since the bridge attachment element 52 can assume a mechanical and / or electrical attachment.

[0053] Figures 13 to 17 Another embodiment of the device 10 is shown. Figures 13 to 16 The positions of transparent display screen 4 which can be configured with the aid of device 10 are shown in each case in a perspective view. Fig.17 A corresponding plan view or a view from above is shown of the inwardly pivoted display screen 4 .

[0054] Fig.13 and 17 In each case, a transparent display screen 4 is shown in a completely swung-in or folded-in state, which allows a wide view through the roof cover 3 of the vehicle. Fig.14 The display screen 4 is shown in a partially pivoted open or exposed state. Fig.15 The display screen 4 is shown in the pivoted open or exposed state. Fig.16 The display screen 4 is shown in a swing-open or open state, in which the display screen is also moved forward and is in contact with the display screen 4. Fig.15 In contrast, the display screen has a slightly differently set orientation angle within the vehicle interior.

[0055] According to Figures 13 to 17The display screen attachment 5 of the embodiment is realized in the form of a frame attachment 53, which forms a circumferential coupling of the transparent display screen 4 on the lever mechanism 15. The frame attachment 53 can be used for power supply or control and / or helps to make the display screen 4 particularly safe and reliable mechanically. Alternatively or additionally, the electrical and / or mechanical attachment can also be realized by the lateral attachment 51.

[0056] According to Figures 13 to 17 In the embodiment of the invention, in addition to the frame attachment 53, two opposite side attachments 51 and a bridge attachment 52 are shown, which can be regarded as part of the frame attachment 53 and / or can be arranged in addition to the frame attachment. Figures 2 to 12 In comparison with the previous embodiments, the bridge attachment 52 and / or the lateral attachment 51 can in particular be configured to be smaller, shorter and / or narrower, since the frame attachment 53 can assume mechanical and / or electrical attachment.

[0057] The described and illustrated exemplary embodiment of the device 10 with a transparent display screen 4 achieves, in particular, one or more of the following advantages:

[0058] The corresponding display attachment 5 realizes one or more clamping holding elements which are not located or are hardly located in the region of the see-through surface of the display 4, so that a complete or almost complete see-through through the image-generating transparent surface of the display 4 is achieved;

[0059] In the parking position of the display screen 4 , the passengers can still have a view through the roof 3 in the roof region, since the display screen 4 is particularly transparent in the parking position in the switched-off state.

[0060] The induction of so-called “motion sickness” is significantly reduced, since, for example, a passenger or observer in the position of use can see a partially transparent moving image, but can still look forward through the display screen 4 and perceive parts of the moving peripheral device.
