Abstract
Description
Field of the Invention
[0001] The present invention relates to a display assembly adapted for attachment of a display device inside a vehicle. The present invention also relates to a method of operating the display assembly and its use in a vehicle. Background Art
[0002] Display assemblies in vehicles are known from the prior art, for example, in which the display assembly is attached to the inner side of the vehicle roof and the display can be easily pivoted from a storage position to an operating position in which the vehicle occupants can view the display screen.
[0003] Although these display assemblies can be pivoted manually, motorized pivoting systems are becoming increasingly common in the art. A motorized display assembly can simply pivot about a single axis to pivot from a storage position to an operating position and back. Alternatively, the display assembly can pivot about an axis and also slide along the roof to a fixed storage position.
[0004] The latter option typically requires two separate movements. In one movement, the display assembly moves along the X-axis extending in the longitudinal direction, and in one movement, the display moves along the Z-axis extending in the vertical direction. Known solutions require two drive motors to perform the respective movements. One motor moves the display along the X-axis and one motor moves the display along the Z-axis.
[0005] Two such drive motors require sufficient space along the roof to accommodate these drive motors. It also increases the complexity of controlling the two drive motors to cooperate with each other in the correct sequence and at the correct timing to move from one movement to another. Moreover, the additional motor means additional weight of the assembly and thus additional weight of the vehicle.
[0006] There are some single drive motor designs, but they are generally still bulky and require additional structures such as spring elements to provide the downward force required to fix the display assembly in its operating position. In particular, when the display has moved along the Z-axis but is still traveling a little along the X-axis, the display assembly needs to be properly fixed in the downward direction for this last bit of travel.
[0007] Accordingly, it is an object of the present invention to provide a display assembly to alleviate these drawbacks. Summary of the Invention
[0008] This object is achieved by providing a display assembly for attaching a display device inside a vehicle, the display assembly comprising: a guide rail along the X-axis; a sliding guide arranged on the guide rail; a locator bend arranged inside the sliding guide; a sliding rod slidably connected to the locator bend; and a foldable display mount attached to the sliding rod, wherein the locator bend includes a lower bent portion and an upper bent portion, the sliding rod includes a sliding groove, and the foldable display mount includes at least one sliding foot slidably connected to the sliding groove, the sliding rod is slidably guided inside the locator bend so that the foldable display mount moves along the X-axis, and the foldable display mount is guided inside the sliding groove so that the foldable display mount tilts towards the Z-axis.
[0009] The guide rail generally extends longitudinally along the X-axis so as to follow the contour inside the vehicle roof. The guide rail can be part of the roof assembly. The guide rail can also be part of a fixed or movable vehicle sunroof assembly. The display assembly can include a single guide rail in the form of a U-shape, having two portions extending along the X-axis. The display assembly can include two or more separate guide rails, such as a pair of guide rails that are mirror images of each other. The pair of guide rails can include multiple rail portions or components that substantially form two mirror-image guide rails.
[0010] The sliding guide can be an integral part of the guide rail. The sliding guide can be, for example, a part formed or molded inside the guide rail and operative as a sliding guide. Alternatively, the sliding guide can be a separate component that can be attached to the guide rail by any conventional fixing means.
[0011] The locator bend arranged inside the sliding guide can extend along the X-axis. The locator bend can also only partially extend along the X-axis. For example, the lower bent portion of the locator bend can extend along the X-axis, wherein the upper bent portion can deviate from the X-axis, thereby creating an inclined bent portion. Thus, the lower bent portion can be horizontally oriented, while the upper bent portion can be diagonally or slightly vertically oriented.
[0012] The sliding rod can be slidably connected to the locator bend by a sliding pin or block on the first side of the sliding rod. The sliding rod includes a sliding groove located on the second side of the sliding rod. The first side and the second side can be on opposite sides or adjacent sides. The sliding rod can be manually operated or operated by a single drive motor.
[0013] The foldable display mount is connected to a sliding rod by means of at least one sliding leg, and the at least one sliding leg is slidably connected to a sliding groove of the sliding rod. The sliding leg may have a pin or a block extending into the sliding groove. The foldable display mount may further include a support rod attached to the at least one sliding leg. The support rod may pivot about the Y-axis on the at least one sliding leg. The support rod may serve as a carrier for the display or a display fixing frame suitable for holding the display. In a preferred example, the foldable display mount includes two sliding legs, each sliding leg including a support rod, wherein the support rods are attached to each other to form an X or Y pattern, such as a scaling or scissor-like structure, wherein one support rod serves as a carrier for the display or a display fixing frame. In the said example, the first support rod is connected to the first sliding leg, and the second support rod is directly connected to the second sliding leg. During operation, when the first sliding leg approaches the second sliding leg, the display starts to pivot. The distance between the two legs, the length of the support rods, and the intersection position where the two support rods meet affect the magnitude of the force required to tilt the display. The speed of movement of the first sliding leg affects the pivoting speed of the display. Preferably, these parameters are selected such that the magnitude of the required force is minimized while maintaining sufficient stiffness throughout the assembly and the display pivots in a smooth manner.
[0014] By providing a sliding rod within a sliding guide and connecting the foldable display mount to the sliding rod, such a sliding rod can perform two movement actions. By moving the sliding rod within the sliding guide, the foldable display mount moves along the X-axis. By moving the sliding legs of the foldable display mount within the sliding rod, the foldable display mount tilts towards the Z-axis. A locator bend within the sliding guide enables the sliding rod to switch between the two movement actions and locks the sliding rod in the Z-axis direction.
[0015] More particularly, in the starting position, the foldable display mount connected to the sliding rod is folded, and the sliding legs are also in the starting position. When movement is started manually or automatically, the sliding rod moves in the lower bent portion of the sliding guide, and the sliding legs remain in the starting position, thus holding the foldable display mount in the folded state. Once the sliding rod transitions from the lower bent portion to the upper bent portion, the sliding rod is repositioned such that the first sliding leg can start moving from its starting position towards the operating position. The sliding rod remains in its transition position until the first sliding leg is at or near its operating position. When the first sliding leg is at or near its operating position, the foldable display mount unfolds, and the sliding rod can travel within the upper bent portion to cause the unfolded display mount to further move along the X-axis towards the end position. To fold and store the display back to its starting position, the movement is reversed.
[0016] Thus, the combination of the locator bender and the sliding rod allows the sliding rod to move by a single manual or automatic driving device while performing two separate actions and fixing the degree of freedom within the Z-axis direction.
[0017] For reference, in a vehicle, the X-axis is typically also represented as the longitudinal direction or longitudinal axis extending from the front to the rear of the vehicle, the Y-axis is represented as the lateral direction or lateral axis extending from the left side to the right side of the vehicle, and the Z-axis is represented as the vertical direction or vertical axis extending from the top to the bottom of the vehicle.
[0018] In an embodiment, the sliding guide is provided as an integral part of the guide rail or as a separate component fixed to the guide rail.
[0019] By providing the sliding guide as an integral part of the guide rail, the amount of components used can be minimized. When provided as an integral part of the guide rail, the sliding guide can be one of many integral parts, each having a different function. To provide the sliding guide as an integral part, the guide rail and the sliding guide can be formed from a single part, or can be formed by providing a sliding guide portion within the internal structure of a preformed guide rail. By providing the sliding guide as a separate component fixed to the guide rail, the guide rail can also be provided with other components. When provided as a separate component, the sliding guide can operate or be adjusted independently within the guide rail.
[0020] In an embodiment, a locator bender is provided, wherein the rear end of the lower bending portion is connected to the front end of the upper bending portion, thereby forming a shallow S-shaped bending connection between the lower bending portion and the upper bending portion.
[0021] By providing a locator bender having a lower bending portion and an upper bending portion forming a shallow S-shaped bend, the curvature allows the sliding rod slidably connected to the locator bender to transition slowly between the lower bender and the upper bender without a hard stop moment. Thus, the action of the display assembly moving along the X-axis and the action of the display assembly tilting towards the Z-axis transition smoothly with each other, thereby achieving a smoother motion appearance during the movement.
[0022] In an embodiment, a locator bender is provided, wherein the rear end of the lower bending portion is connected to the front end of the upper bending portion, thereby forming a steep S-shaped bending connection between the lower bending portion and the upper bending portion.
[0023] By providing a locator bend having a lower bend portion and an upper bend portion that form a steep S-bend, the curvature allows a sliding rod that is slidably coupled to the locator bend to encounter a hard stop or a stopping moment during the transition between the lower bend portion and the upper bend portion. Accordingly, the movement of the display assembly along the X-axis will be temporarily aborted or completely stopped while the display assembly tilts towards the Z-axis. This results in a more distinct transition. Also, as opposed to longer or shallower bends, a smaller curvature height is required to effect the transition of movement. Accordingly, the overall height of the sliding guide having the locator bend can be minimized.
[0024] In an embodiment, the sliding rod is further provided with a sliding pin or block on a first side of the sliding rod and disposed within the locator bend, and further includes a stop portion within a sliding slot on a second side of the sliding rod, the stop portion being arranged such that the movement of at least one sliding leg that is slidably coupled to the sliding slot is stopped.
[0025] The sliding rod may be provided with a plurality of sliding pins, blocks, or a combination thereof to further guide different movements and actions during the movement of the sliding rod. Using a plurality of such pins, blocks, or both can increase the stability and fixation of the sliding rod during movement. The first side and the second side of the sliding rod may be on opposite sides or on adjacent sides.
[0026] In an embodiment of the display assembly, the foldable display mount further includes at least one connecting strut that is coupled to at least one sliding leg, the sliding leg being capable of rotating about the Y-axis of the at least one sliding leg.
[0027] The strut may pivot about the Y-axis on the at least one sliding leg. The strut may serve as a carrier for the display or a display fixing frame suitable for holding the display. In a particular example, the foldable display mount includes two sliding legs, each sliding leg including a strut, wherein the struts are attached to each other to form an X or Y pattern, such as a zoom or scissor-like structure, wherein one strut serves as a carrier for the display or a display fixing frame.
[0028] In an embodiment, the display assembly further includes a display attached to the foldable display mount.
[0029] The display may be directly attached to at least one sliding leg of the display mount, attached to at least one strut coupled to the sliding leg, or attached to both. In a particular example, the display is attached to at least one strut, and the strut has a surface area for suitably supporting the display. This increases the stability of the display mount while allowing sufficient rotational freedom at the connection of the strut to the sliding leg.
[0030] In an embodiment, the display assembly further includes a display fixing frame attached to a foldable display mount that carries or supports the display.
[0031] The display fixing frame can be directly attached to at least one sliding leg of the display mount, attached to at least one strut connected to the sliding leg, or attached to both. In a particular example, the display is attached to at least one strut, and the strut has a surface area that appropriately supports the display. This increases the stability of the display installation while allowing sufficient rotational freedom at the connection of the strut to the sliding leg. The display can also be mounted only on the display fixing frame or on the display fixing frame and at least a portion of the display mount.
[0032] In an embodiment, the display assembly further includes a drive motor and a cable connected between the drive motor and at least one sliding leg to automatically move the at least one sliding leg forward or backward by driving the cable.
[0033] The cable can be any suitable cable for moving the sliding leg forward or backward, such as a push-pull cable. The cable can push and / or pull the sliding leg. The drive motor can be any suitable electric drive motor for driving the cable, such as a spindle motor or a linear motor.
[0034] In an aspect of the present invention, there is provided a roof assembly for a vehicle, the roof assembly including a display assembly.
[0035] The roof assembly can be a fixed roof with or without a glass panel, wherein the display assembly is attached to the roof assembly.
[0036] In an embodiment, the roof assembly further includes a roof panel provided with a glass lamp and a roller screen movable between a closed position and an open position.
[0037] The roof panel can be a fixed roof panel, a movable roof panel, or a combination of both. The display assembly can be provided together with the guide rails for the movable panel and / or the roller screen. When provided together with the guide rails for the movable panel and / or the roller screen, it is particularly advantageous to provide the sliding guide of the display assembly as a separate component fixed to the guide rails.
[0038] In another aspect of the present invention, there is provided a method for operating the above-described display assembly, which comprises the following steps: causing a slide bar slidably connected to a locator bend of a slide guide to move from a first position within the locator bend towards a second position within the locator bend; and causing a foldable display mount attached to the slide bar to move by causing at least one slide leg slidably connected to a slide groove to move from a first position within the slide groove towards a second position within the slide groove, during the transition between a lower bent portion and an upper bent portion of the locator bend, the movement of the slide bar is temporarily slowed down or aborted.
[0039] By providing a slide bar within the slide guide and connecting the foldable display mount to the slide bar, such a slide bar can perform the two movement actions as described. By moving the slide bar within the slide guide, the foldable display mount moves along the X-axis. By moving the slide legs of the foldable display mount within the slide bar, the foldable display mount tilts towards the Z-axis. The locator bend within the slide guide enables the slide bar to transition between the two movement actions and locks the slide bar in the Z-axis direction. Therefore, the combination of the locator bend and the slide bar allows the slide bar to be moved by a single manual or automatic drive device while performing two separate actions and fixing the degree of freedom in the Z-axis direction.
[0040] In an embodiment, the method further comprises the following steps: causing the slide bar to perform a first movement towards the rear end of the lower bent portion within the lower bent portion; keeping the slide legs in a first position within the slide groove during the first movement; causing the slide legs to move from their first position towards a second position in the slide groove while keeping the slide bar at the rear end of the lower bent portion, thereby unfolding the foldable display mount; starting a second movement of the slide bar when the slide legs are in their second position; causing the slide bar to transition from the lower bent portion to the upper bent portion and move towards the rear end of the upper bent portion, thereby causing the unfolded display mount to further move along the X-axis.
[0041] In this embodiment, before the slide bar further moves, the movement of the slide bar is temporarily aborted, thereby creating a hard stop. This allows the display mount to unfold before moving towards the operating position.
[0042] In another aspect of the present invention, there is provided a use of the above-described display assembly for attaching a display device to the interior of a vehicle, which comprises the foregoing steps.
[0043] The display assembly can be provided inside a vehicle (especially an automobile, such as a car or a truck), wherein the display assembly is operated such that a display attached to the display assembly moves from a closed or stored position to an open or operating position and returns from the open position to the closed position.
[0044] In yet another aspect of this embodiment, there is provided a use of a roof assembly for a vehicle for attaching a display device inside the vehicle, which, as described above, includes the above method steps.
[0045] The display assembly may be provided within the roof assembly of the vehicle, particularly the roof of an automobile, such as a car or a truck, wherein the display assembly is operative such that a display attached thereto moves from a closed or stored position to an open or operative position and back from the open position to the closed position.

[0059] In the following description, the spatial references (such as the X-axis, Y-axis or Z-axis) are with respect to the overall orientation of the vehicle, such as a passenger car, and more particularly with respect to the driver behind the steering wheel of such a vehicle. In some of the figures, schematic representations of the X-axis, Y-axis and Z-axis are given to enhance the sense of direction.
[0060] In Figure 1 , the display assembly is shown as including a guide rail 1 having a guide rail groove 11 and a guide rail slot 12. Also shown is a sliding guide 2 disposed within the guide rail 1, the sliding guide 2 including a lower curved portion 21 and an upper curved portion 22. A sliding rod 3 having a sliding slot 31 is provided, which is slidably connected to the sliding guide 2. A first sliding foot 4 and a second sliding foot 5 are attached to the sliding rod 3. A foldable display mount 6 is attached to the first sliding foot 4 by a first connecting strut 61, and the mount 6 is also attached to the second sliding foot 5 by a second connecting strut 62. The first connecting strut 61 and the second connecting strut 62 form a scissor-like structure. The display 7 is indirectly mounted on the first connecting strut 61 through a display fixing frame 8 attached thereto.
[0061] In addition, a sliding rod front stopper 311 and a sliding rod rear stopper 312 can be distinguished, which will be shown in more detail in Figure 2 . Also, a first sliding foot guide rod 41 of the first sliding foot 4 can be seen and will be shown in more detail in Figure 4 .
[0062] When the sliding guide 2 is disposed within the guide rail 1 (thus forming an integral part of the guide rail 1), the sliding rod 3 having the first sliding foot 4 and the second sliding foot 5 is disposed within the guide rail groove 11 of the guide rail 1.
[0063] As shown, the display assembly is in a transitional stage of operating the display assembly. In other words, the display assembly is in an unfolded state, in which the display 7 is tilted towards the Z-axis, while the slider 32 of the sliding rod 3 is in a first position within the upper curved portion 22. Thus, the sliding rod 3 is in a transition between the lower curved portion 21 and the upper curved portion 22. The first sliding foot 4 is close to a second position within the sliding slot 31, but still has to travel to reach the second position in order to fully unfold the display assembly to the operating position. Further details of the movement will be explained in the subsequent figures.
[0064] Figure 2 shows an enlarged view of region A as shown in Figure 1 where the front stop 311 of the slide bar 3 can be seen more clearly. Also, the slider 32 of the slide bar 3 can be more clearly distinguished and is located within the upper curved portion 22.
[0065] The front stop 311 of the slide bar is an angled portion of the slide groove 31. When the slide pin 42 of the first slide leg 4 (not shown in this figure) moves within the slide groove 31, it can be (temporarily) locked in the front stop 311 of the slide bar.
[0066] In Figure 3 shows an enlarged view of region B of Figure 1 . The guide rail groove 11 and the guide rail slot 12 can be more clearly distinguished. The guide rail groove 11 in this figure is shown as two smaller grooves. The guide rail slot 12 is arranged perpendicular to the guide rail groove 11. The guide rail slot 12 can also be arranged in the same plane as the guide rail groove 11, or at any angle between the same plane and the perpendicular position.
[0067] In Figure 4 shows an enlarged view of region C of Figure 1 . The guide rod 41 of the first slide leg 4 can be distinguished. The rear stop 312 of the slide bar can also be seen more clearly in this figure, where the slide pin 42 of the first slide leg 4 is positioned close to the rear stop 312.
[0068] The guide rod 41 of the first slide leg can be slidably connected to the guide rail slot 12 of the guide rail 1 (not shown in this figure). This allows the first slide leg 4 to move stably and reliably within the guide rail 1, thus restricting the movement of the leg 4 to only along the X-axis.
[0069] Similar to the front stop 311 of the slide bar (not shown), the rear stop 312 of the slide bar is an angled portion of the slide groove 31. When the slide pin 42 of the first slide leg 4 moves within the slide groove 31, it can be (temporarily) locked in the rear stop 312 of the slide bar. When the slide pin 42 is located within the rear stop 312, the first slide leg 4 is in its second operating position.
[0070] Moreover, it is also shown that the second slide leg 5 is not slidably connected to the slide groove 31, but is fixed on the axis at the end portion of the slide bar 3 and can pivot about the axis.
[0071] Figure 5 shows as previously in Figure 1The display assembly shown in the figure, where the display assembly is in the storage position. Both the display 7 and the display fixing frame 8 extend along the X-axis parallel to the guide rail 1. The sliding rod 3 is in the first storage position within the lower locator bend 21 of the sliding guide 2. The first sliding foot 4 is in the first storage position within the sliding guide 31 of the sliding rod 3.
[0072] Figure 6 shows the display assembly as previously shown in Figure 1 where the display assembly is in the operating position. Both the display 7 and the display fixing frame 8 are inclined towards the Z-axis, and the Z-axis extends vertically downward relative to the guide rail 1. The sliding rod 3 is in the second operating position within the upper locator bend 22 of the sliding guide 2. The first sliding foot 4 is in the second operating position within the sliding guide 31 of the sliding rod 3.
[0073] In Figure 7 a magnified view of the operation as discussed in Figure 1 can be seen. The display assembly shown in the figure is in the transition stage of operating the display assembly. In other words, the display assembly is in the unfolded state, where the display 7 is inclined towards the Z-axis while the slider 32 of the sliding rod 3 is in the first position within the upper bend portion 22. Therefore, the sliding rod 3 is in the transition between the lower bend portion 21 and the upper bend portion 22. The first sliding foot 4 is close to the second position within the sliding groove 31, but still has to travel to reach the second position in order to fully unfold the display assembly to the operating position.
[0074] In addition, in Figure 7 it can be seen that the sliding guide 2 is perforated in order to reduce the amount of material used and thus reduce the weight of the sliding guide 2 without sacrificing its strength. It can also be seen that the length of the first connecting rod 61 is kept to a minimum, and the rod 61 includes some cutouts, which are also used to reduce weight. The second connecting rod 62 also has cutouts in its inner body in order to reduce its weight without sacrificing its strength.
[0075] Figure 8A 、 9A and 10A schematically show several actions of the sliding rod 3 within the locator bends of the sliding guide 2 during the operation of the display assembly, while Figure 8B 、 9B and 10B show the corresponding actions of the first sliding foot 4 (not shown in these figures) within the sliding groove 31 of the sliding rod 3 when a driving force is applied to the first sliding foot 4 to operate the display assembly. The driving force is provided to the first sliding foot 4 through a drive cable connected to a drive motor.
[0076] In a first action, the slider 32 of the sliding rod 3 moves from its starting position in the lower bent portion 21 towards the S-bending connection portion S, as Figure 8A shown, where the movement is indicated by an arrow, so that the sliding rod 3 moves from its starting position towards the operating position. At the same time, as Figure 8B shown, the sliding pin 42 of the first sliding leg 4 remains within the sliding rod front stopper 311 during the first action, thereby holding the first sliding leg 4 in its starting position during the first action movement and allowing the sliding rod 3 to move when a driving force is applied to the first sliding leg 4 without causing the first sliding leg 4 to move within the sliding groove 31.
[0077] When the slider 32 reaches the S-bending connection portion S, its movement temporarily stops, as Figure 9A shown, so that the arrow of the slider 32 is omitted to indicate no movement, thereby initiating the second action. The movement of the sliding rod 3 also stops. At the same time, the sliding pin 42 will leave the sliding rod front stopper 311 and move towards the end position within the sliding groove 31, as Figure 9B shown. Due to the design and shape of the sliding rod 3 combined with the sliding guide 2, the sliding pin 42 can leave the front stopper 311. In this example, due to the steep S-bending connection portion S, the slider 32 can strike the wall portion of the lower bent portion 21 to provide sufficient resistance to allow the sliding pin 42 to be released from the sliding rod front stopper 311 while still applying a driving force on the first sliding leg 4. Alternatively, when the slider 32 is located at the S-bending connection portion S, a different shape of the sliding rod 3 towards the front stopper 311 can be used to slightly tilt the sliding rod 3 to allow the sliding pin 42 to be released. For example, when using a smooth S-bending connection portion S, a gradual tilt of the sliding rod 3 may occur when the slider 32 moves slowly within the S-bending connection portion S, thereby releasing the sliding pin 42.
[0078] When the sliding pin 42 is in the end position of the sliding groove 31, the third action is initiated, as Figure 10B shown. In the end position, the sliding pin 42 allows the slider 32 of the sliding rod 3 to transition from the lower bent portion 21 towards the upper bent portion 22. In this example, the sliding pin 42 falls into the sliding rod rear stopper 312 (see Figure 4 ), thereby tilting the sliding rod 3 and pushing the slider 32 towards the upper bent portion 22. Alternatively, the S-bending connection portion S can be designed, for example, with a smoother S-bend, such that when the sliding pin 42 is in its end position, the driving force on the first sliding leg 4 allows the slider 32 to transition through the S-bend. In the case where the slider 32 transitions to the upper bent portion 22, the slider 32 travels towards the end position within the bent portion, as Figure 9BAs shown. In this movement, the foldable display mount 6 connected to the first sliding foot 4 has been deployed and will move longitudinally along the X-axis towards the operating position in the deployed state, so that the display 7 is in its operating state. To store the display 7 back to the storage position, the actions and movements are reversed.
