Description

Technical Field

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

[0002] Some motor vehicles have display devices that can provide entertainment programs as needed and help improve the comfort of the motor vehicle. In some cases, such display arrangements have a kinematic design that allows the display device to be folded up and folded out as needed. One challenge is to be able to arrange such electronic entertainment systems in a space-saving and cost-effective manner. Summary of the invention

[0003] The object of the present invention is to provide a device for adjusting a display device for a vehicle roof which allows the required adjustments of the display device to be configured reliably and safely and also contributes to achieving a cost-effective and comfortable motor vehicle.

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

[0005] The device for adjusting a display device for a vehicle roof according to the present invention comprises a lever mechanism, which can be coupled to a display holder of the display device and is configured to be able to pivotally open and pivotally enter and move the display device, wherein the lever mechanism comprises a first guide slider and a second guide slider that can be moved along a guide rail by a drive unit. The lever mechanism also comprises a first pivot rod and a second pivot rod, which are coupled to each other so as to be pivotable about a corresponding pivot axis, and the first pivot rod and the second pivot rod are coupled to the guide slider.

[0006] The guide rail can be considered as a component of the device or the vehicle roof or as a separate component. The device is designed for use on and / or on the guide rail. The same applies to the display device including the display and the display holder. The display device can be considered as a component of the device or the vehicle roof or as a separate component. The device is designed for use in conjunction with the display device.

[0007] The device further comprises a spring element and a spring guide element. The spring element comprises a first spring arm and a second spring arm and is coupled to a second guide slider and a second pivot rod. The spring guide element is fixed to an arrangement relative to the guide rail or the roof and comprises a guide portion having at least one first end stop. The guide portion is configured to fit the end of the first spring arm so that the end of the first spring arm can engage in the guide portion and can move along the guide rail in a predetermined manner within the guide rail.

[0008] The device further comprises a locking element. The locking element is coupled to the second guide slide and is mounted to be rotatable about the pivot axis. The locking element can be switched from a first state in which the display device is folded and locked to a second state in which the display device is unlocked and can be pivoted open or pivoted in by means of the first guide slide and the spring element. In the unlocked second state, the two guide slides can be moved relative to each other, whereby the spacing between the two guide slides can be changed in a predetermined manner, and the pivoting opening and pivoting in of the display device can be adjusted in a predetermined manner by means of the two pivot rods.

[0009] The device described enables comfortable and reliable adjustment of the desired position and orientation of a display device, which can also be realized cost-effectively and integrated in a space-saving manner into the roof structure of a motor vehicle. The device uses an electrically drivable mechanism and only requires a drive unit to activate the two guide slides and to pivot and move the display device. The device can thus be realized with a particularly manageable and space-saving construction with a small number of components and allows comfortable lowering in the downward direction as well as positioning and adjustment of a display in the vehicle interior.

[0010] In the context of this description, the terms "top", "bottom", "front", "rear", "left", "right" and "vertical" and "horizontal" refer to directional information or orientation of the device for operational use in a motor vehicle to be used. The display device described, which can be lowered and oriented as required by the device, is particularly intended for vehicle occupants on rear seats. The horizontal component of movement therefore refers to a plane that is essentially parallel to the roof of the vehicle. The vertical direction therefore occurs in a plane that is essentially perpendicular to the horizontal plane or the roof of the vehicle. The front of the vehicle is arranged at the front and the rear of the vehicle is arranged at the rear.

[0011] According to a development of the device, the spring element on the first spring arm has a hook-shaped end which engages in a guide recess of the spring guide element. The guide recess can be designed as a channel or a groove. With respect to the longitudinal axis of the roof and the freedom of movement provided by the spring arm, the guide recess can be open on both sides, closed on both sides or open or closed on one side. The guide recess can also be open at the top and / or at the bottom in order to provide at least one channel for the end of the first spring arm and to provide a reliable and controllable guidance of the first spring arm.

[0012] According to a further development of the device, the guide recess is delimited in a U-shaped manner, for example, the guide recess is delimited laterally by the side walls of the spring guide element and longitudinally by the first end stop. Thus, the guide recess can be open on one side and provide a predetermined guide channel for the first spring arm. Thus, the first end stop represents a controlled movement end of the first spring arm and the second guide slide and allows a simple and reliable unlocking and locking of the display device. The second guide slide is coupled to the spring element and moves in a predetermined manner until the first spring arm hits the first end stop. Then, further movement of the second guide slide in the direction of the guide rail or the longitudinal axis is intentionally blocked, so that the second guide slide now forms a fixed support inside the guide rail, and the first guide slide can approach the support to pivot open the display device. Thus, when the display device is pivoted in, the first guide slide moves away from the fixed second guide slide.

[0013] According to a further development of the device, the spring guide element comprises a further second end stop, so that the two end stops delimit the guide recess on opposite sides and limit the mobility of the first spring arm along the longitudinal axis of the vehicle roof in a predetermined manner.

[0014] According to a further development of the device, the first spring arm contacts the first end stop in the first state of the display device and / or contacts the second end stop in the second state of the display device. The end stops thus represent controlled movement ends of the first spring arm and the second guide slide.

[0015] According to a further development of the device, the guide recess of the spring guide element and the locking element are configured to be geometrically adapted to each other. For example, the guide recess can form an upwardly open pocket that allows a predetermined mobility of the first spring arm and the second guide slide connected thereto. This mobility is adapted to the shape of the locking element, in particular in relation to the shape of the locking element, so that a reliable movement and / or rotation of the locking element can be achieved by driving the first guide slide and the second guide slide coupled thereto until the display device is unlocked or locked.

[0016] According to a further development of the device, the spring guide element comprises a fastening element, by means of which the spring guide element can be fixedly attached to the guide rail. For example, the fastening element can be designed in the form of a bolt or a screw.

[0017] According to a further development of the device, the spring guide element comprises a support element supporting the first spring arm. The support element can in particular be designed such that it is in direct contact with the first spring arm, for example at the lower surface, at the end region, thereby providing a particularly safe and reliable support.

[0018] According to a further development of the device, a second spring arm is coupled to the second pivot rod in such a way that it can apply a force to the second pivot rod, which drives the second pivot rod in a direction to form a first state of the display device. The first spring arm can provide a counterweight or a reaction force for the second spring arm, in particular in connection with the above-mentioned support element. For example, the second spring arm engages at a dedicated opening of the second pivot rod or engages below the second pivot rod, thereby allowing a particularly gentle lowering of the display device, because its spring force counteracts the weight of the display device. The two spring arms can be coupled together, in particular by a winding, for example, which is wound around a pin on the second guide slide and provides the second spring arm with the required freedom of movement for lowering the display device. In this way, the spring element represents an elastic compensation element, which introduces coupling and elastic properties into the device in a targeted manner.

[0019] According to a further development of the device, the locking element has a locking arm which is configured to fit into the locking receiver such that in a first state the locking arm is arranged outside the locking receiver and in a second state the locking arm is arranged inside the locking receiver.

[0020] According to a further development, the device is configured relative to the ready-to-operate state on the roof so that, starting from a first state of the display device, a locking element having a locking arm can be driven along the longitudinal axis of the roof by means of a first guide slider and a spring element and can be moved in a direction toward the lower surface of the roof until the locking arm engages with the locking receiver, thereby forming a second state of the display device, wherein the display device can be lowered by further movement of the first guide slider.

[0021] According to a further development, the device comprises a guide rail, with which the device can be coupled to a representative body of the vehicle roof, wherein the guide rail has an opening forming a locking receiver. Thus, the locking element can be configured to cooperate with the guide rail. The guide rail can also have an end stop element, against which the first guide slide moves when the display is folded and locked, thereby specifying a reliable and safe end position or parking position of the display device. Such an end stop element can be represented by a button, which confirms that the locking position has been reached and prevents further movement of the display device.

[0022] The embodiment options of the described device allow the display device in a motor vehicle to be lowered and turned gently and quietly in various situations. The structure of the device has a small number of components, is easy to manage and cost-effective, and since no noise-related switching processes are required, a reliable and safe orientation of the display device in the vehicle interior can be achieved by a single electric drive. No separate switching element is required for unlocking. Therefore, it is not necessary to move the locking element out of a pocket or an opening and reengage it in another position. The spring element is guided in the slotted guide, serves as an unlocking element and gently pushes the locking element at a predetermined position and opens the locking hook.

[0023] In the first state, the display is in a parking position, for example, in the rear area above the head area of ​​the vehicle occupants, essentially parallel to the vehicle roof. When the display is folded out, it is initially moved slightly forward, so that the lock is opened and the display is transferred to the second pivotable state. The spacing between the two guide slides can now be reduced in a predetermined manner so that the pivot lever can be pivoted in a predetermined manner about the corresponding pivot axis and release the display or the lower edge of the display downward into the vehicle interior.

[0024] By cooperating with the pivot rod, the orientation angle of the display can be adjusted, for example, to 65°-85° in the direction toward the interior of the vehicle. This orientation angle refers to the angle between the main extension plane of the display and the horizontal plane or parking position in which the display is folded. Alternatively, the orientation angle can refer to the angle enclosed between the main extension plane of the display and the vertical plane. Thus, an orientation angle of 5°-25° can be adjusted. In particular, the adjustment of the orientation angle is carried out continuously, but can also be carried out in predetermined steps. Thus, the pivoting opening or pivoting in of the display can be stopped even in an intermediate position of 30°, 40°, 50° or 60°. In addition, the device can also be designed to allow other angle ranges for adjusting the display of the display device.

[0025] For example, the lever mechanism or the first guide slide is coupled to the motor via a drive cable. The translational and rotational movements of the display or display device can be simply realized by this one drive unit. Thus, the display device can be moved and pivoted inwardly and outwardly in a controlled and reliable manner to form a pivoted or lifted position of the display device and to adjust the desired angular orientation.

[0026] The device can be implemented in a manageable, cost-effective and space-saving manner, so that the installation space requirements in the vehicle interior can be kept small. The device can be integrated in the roof of a vehicle or arranged on such a roof and still allow the head to move freely and comfortably in the vehicle interior. In this way, controlled movement and blocking of the display device can be provided without noise-related switching processes and contribute to high-quality entertainment in a motor vehicle.

[0027] The vehicle roof of the invention comprises two guide rails, which are arranged on opposite sides of the vehicle roof relative to the longitudinal axis of the vehicle roof, and also comprises an embodiment of the above-mentioned device for adjusting a display device, which device is coupled to the vehicle roof via the guide rails. The device can in particular use existing spaces located in a respective guide rail, which spaces are also configured, for example, for operating a shielding device. In particular, the first and second lever mechanisms can be arranged inside a common guide rail, so that the lever mechanisms share the common guide rail.

[0028] In relation to the vehicle roof, the device may in particular comprise twice the number of components or provide two devices which are configured and arranged substantially mirror-symmetrically with respect to a central or middle longitudinal axis of the vehicle roof. Thus, a vehicle roof with the device contributes to improving the comfort of the motor vehicle and can be produced more economically than conventional tilting devices for displays. Since the vehicle roof comprises an embodiment of the device described above, the above-described features and properties of the device may also be disclosed for the vehicle roof and vice versa.

[0031] Figure 2-3 shows the method for adjusting the Figure 1 A perspective view of an embodiment of an apparatus of a display device on a roof of a vehicle;

[0032] Figure 4-21 Different views are shown according to Figure 2-3 different states of the device.

[0033] Elements having the same structure or function are marked with the same reference numerals in all drawings. For the sake of clarity, in some cases, not all shown elements are marked with reference numerals in all drawings. DETAILED DESCRIPTION

[0034] Figure 1 A perspective view schematically shows a roof 1 of a motor vehicle having a cover panel 3 and a display device 4. For example, the cover panel 3 is a fixed glass element that is immovable relative to the roof 1. Alternatively, the cover panel 3 is movable relative to the roof 1 in order to selectively open and close an opening in the roof 1. The roof 1 can also be without a cover panel 3 and can be a top skin 2 without an opening of a fixed roof or a convertible top that can be folded or folded up and can be stored in the rear area of ​​the motor vehicle. Furthermore, the roof 1 can also form a convertible top with a cover panel 3, wherein the cover panel 3 is designed to be folded together or folded up.

[0035] The vehicle roof 1 further comprises two devices 10 which are arranged on opposite sides of the vehicle roof 1 with respect to the travel direction or longitudinal axis L of the vehicle roof 1. The devices 10 are constructed and arranged in a mirror-symmetrical manner with respect to the longitudinal axis L, so that only one device 10 is described in detail below. Figure 2-21 Explained in more detail, the device 10 has a manageable and space-saving structure, allows for the adjustments required to reliably and safely configure the display device 4 , and contributes to the realization of a cost-effective and comfortable motor vehicle.

[0036] In the context of this description, terms such as "top", "bottom", "front", "rear", "left", "right", "vertical" and "horizontal" refer to directional information, orientation or position of the device 10 for operational use in a motor vehicle ready for operation. The longitudinal axis L of the diagram also has an arrow symbol, which indicates the general direction of travel to improve orientation. The display device 4 is provided in particular for vehicle occupants on the rear seats and can be simply and comfortably lowered and oriented by the device 10 as required.

[0037] Figure 2 and Figure 3 The device 10 is shown in each case in a corresponding perspective view, wherein Figure 2 With guide rail 5, Figure 3 There is no rail 5.

[0038] The device 10 for adjusting the display device 4 on the vehicle roof 1 comprises a lever mechanism, which is coupled to a display holder of the display device 4 and is configured for pivoting opening and pivoting in and for moving the display device 4. The lever mechanism comprises a first guide slide 11 and a second guide slide 12 movable along the guide rail 5 by means of a drive unit. The lever mechanism further comprises a first pivot rod 13 and a second pivot rod 14, which are coupled together so as to be pivotable about a respective pivot axis S1, S2, S3 and are coupled to the guide slides 11, 12.

[0039] The device 10 further comprises a spring element 17, which comprises a first spring arm 18 and a second spring arm 19, and which is wound on a pin and coupled to the second guide slide 12. The device 10 further comprises a spring guide element 20, which is coupled to the guide rail 5 and is fixedly arranged on the guide rail by a fastening element 22, and which comprises a guide portion having a strip-shaped guide recess 21. The guide recess 21 is bounded on both sides along the longitudinal axis L by a first and a second end stop 23 and 24 and provides a predetermined degree of freedom of movement of the spring element 17 and the second guide slide 12 coupled thereto. The guide recess 21 has a substantially strip-shaped annular shape and is configured to fit the hook-shaped end 181 of the first spring arm 18. The end 181 of the first spring arm 18 engages in the guide recess 21 and can be moved in the guide recess 21 in a predetermined manner along the guide rail 5.

[0040] The device 10 further comprises a locking element 15 having a locking arm 151 and a locking hook 16. The locking element 15 is coupled to the second guide rail slider 12 and is mounted to be rotatable about the pivot axis S2. The locking element 15 can be converted from a first state in which the display device 4 is folded and locked to a second state in which the display device 4 is unlocked and can be pivoted open or pivoted into by means of the first guide slider 11 and the pivot rods 13, 14 coupled thereto and thereby by means of the spring element 17. Therefore, in the unlocked second state, the two guide sliders 11, 12 can be moved relative to each other, and the spacing between the two guide sliders 11, 12 can be changed, and the pivoting opening and pivoting into and orientation of the display device 4 can be adjusted in a predetermined manner by means of the two pivot rods 13, 14.

[0041] The first spring arm 18 is mounted so as to be movable in the guide rail 5. The hook-shaped end 181 of the first spring arm 18 engages in the guide recess 21 and can be moved therein between the end stops 23, 24. The second spring arm 19 is coupled to the second pivot lever 14 and exerts a force on the second pivot lever 14, which drives the second pivot lever in the upward direction to form the first state of the display device 4. The first spring arm 18 is supported from below in the region of the end 181 by the support element 25 of the spring guide element 20 and forms a counterweight or reaction force for the second spring arm 19. The second spring arm 19 engages below the second pivot lever 14 and allows a particularly gentle lowering of the display device 4, because its spring force counteracts the weight of the display device 4. The two spring arms 18 and 19 are coupled together by a winding, which is wound around a pin on the second guide slide 12 and provides the second spring arm 19 with the required freedom of movement for lowering the display device 4. In this way, the spring element 17 represents an elastic compensation element, which introduces coupling and elastic properties into the device 10 in a targeted manner.

[0042] Furthermore, an end stop element 26 is introduced inside the guide rail 5, against which the first guide slide 11 moves when the display is folded and locked, thereby specifying a reliable and secure end position or parking position of the display device 4. The end stop element 26 may represent a kind of button which confirms when the locking position is reached and intentionally blocks further movement of the display device 4.

[0043] Figure 4-21 Different positions of the display device 4 are shown in the various views. Figure 4-21 , a left view, a right view and a cross section along a vertical plane perpendicular to the longitudinal axis L of various adjustment positions of the display device 4 are shown respectively.

[0044] Figure 4-6 A first folded and locked state of the display device 4 is shown. The locking element 15 and the locking hook 16 lock the display device 4, the three-point linkage provided by the pivot levers 13, 14 being effectively rigid. Driving the first guide slide 11 backwards causes a synchronous displacement of the second guide slide 12 forwards. The compensating spring element 17 is preloaded for (over)compensating the weight of the screen of the display device 4. The end 181 of the first spring arm 18 is in contact with the first end stop 23. Alternatively, the end 181 and / or the guide recess 21 can be configured such that in the first state, the end 181 is not in contact with the first end stop 23.

[0045] Figure 7-9 The configuration of the second state is shown, in which the display device 4 is still folded but unlocked, and thus released to be able to pivot open. Via the first guide slide 11, the spring element 17 is moved forwards via the pivot rods 13, 14, and the end 181 moves away from the first end stop 23 until it contacts the second end stop 24. With this forward movement, the spring element 17 pushes the second guide slide 12 to the front, so that the coaxially mounted locking element 15 is also pressed against the leg spring element 27 (see Fig. 9 and Fig.11 ) is pushed forward and downward in a preloaded manner, and the locking arm 151 of the locking element 15 penetrates into the locking receiver 6, which is provided for this purpose and is configured as a recess at a predetermined position in the guide rail 5. The locking hook 16 is thus unlocked by the opening torque of the leg spring element 27 and the cutout or switching contour in the guide rail 5. The second guide slide 12 is now fixed in its position and serves as a fixed bearing. The display device 4 is released for pivoting downward to open into the vehicle interior.

[0046] Figure 10-12 The state in which the display device 4 has been folded out slightly is shown.

[0047] Figure 13-15 Shown with Figure 10-12In comparison, the display device 4 is in a state where it is further folded out.

[0048] Figure 16-18 Shown with Figure 13-15 In comparison, the display device 4 is in a state where it is further folded out.

[0049] For example, Figure 19-21 The fully folded-out state of the display device 4 is shown, with the desired orientation angle for pleasant and comfortable operation and / or viewing angle. The engagement of the first spring arm 18 on the end stop 24 is preferably secured by a vertical Z-direction bearing pin.

[0050] Further movement of the drive slide or first guide slide 11, for example rearward movement, is blocked in a predetermined manner by the position of the drive cable and the geared motor of the drive unit. The blocking portions and end stops 23, 24 and 26 also serve to fix the display device 4 in the event of a collision and to counteract improper operation of the display device 4, for example if it is pulled further to the front or pushed further to the rear.

[0051] By means of the described embodiments of the device 10, in each case the mechanism is provided with an electrically adjustable display direction, which provides some advantages compared to conventional designs, for example, allowing the display to be pivoted using a drive motor connected to the back of the display. In particular, the space requirement in the vertical direction can be kept small, so that the parking position of the display device 4 is not so close to the head position of the vehicle occupant, and the field of vision in front is not restricted, or is less restricted. The device 10 can also be implemented in a cost-effective and space-saving manner, with a particularly manageable structure and few components. The device 10 can be actuated, in particular by an electric drive device fixedly mounted in the roof 1. The second guide slide 12 does not require an additional drive device and an additional drive cable.
