Description

Technical Field

[0001] This disclosure relates to an apparatus for deploying a display unit. More specifically, this disclosure relates to an apparatus for deploying a display unit located within a shock-absorbing pad, and the apparatus controls the tilt of the display unit in the fore-and-aft direction, taking into account the driving state or the state of the vehicle seat. Background Technology

[0002] Generally, vehicles are equipped with a display device near the driver's seat to provide a variety of information. This display device can provide information such as the route from the origin to the destination and the vehicle's current location.

[0003] In addition, the display device can play music or video, receive terrestrial or satellite broadcast signals and display these signals on the screen, and provide information about the vehicle's status or other convenient information for the user (such as weather and news).

[0004] Traditional vehicle display devices are configured to unfold their display units by moving them vertically from their housing state using a lead screw. However, since the speed at which the display unit moves is determined by the lead screw pitch and the motor speed, this presents a problem: slow drive speed and inability to tilt the display unit.

[0005] The information disclosed above in the background section is only intended to enhance the understanding of the background of this disclosure. Therefore, the background section may include information on related technologies that are not known to those skilled in the art. Summary of the Invention

[0006] Therefore, it is necessary to address the aforementioned problems with low-speed and tilted display units. Furthermore, it is necessary to develop display units that can be actively controlled in response to changes in the driving environment or seat position. In addition, it is necessary to develop technologies that control the tilt of the display unit and the distance between the user and the display unit in response to the external environment of the vehicle.

[0007] This disclosure addresses the problems described above in relation to related technologies. The objective of this disclosure is to provide a means for deploying a display unit such that the angle of the display unit is controllable according to the driving state or the vehicle seat position.

[0008] Another objective of this disclosure is to provide a means for deploying a display unit by sliding along a previous cowl cross bar, thereby changing the position of the display unit according to the vehicle's driving conditions.

[0009] The objectives of this disclosure are not limited to those mentioned above. Other objectives not mentioned herein will be readily apparent to those skilled in the art from the following description, and will become apparent with reference to embodiments of this disclosure.

[0042] In the following description, embodiments are described in detail with reference to the accompanying drawings. Throughout the specification, the same or similar parts are indicated by the same reference numerals, and repeated descriptions thereof have been omitted.

[0043] This disclosure relates to an apparatus for deploying a display unit 100. Specifically, this disclosure relates to an apparatus for deploying a display unit 100, the apparatus including a rollable display that can be rolled into and released from a shock-absorbing pad 10 disposed in the passenger compartment of a vehicle.

[0044] The display unit 100 can be wound into the housing 200 by a winding unit located within the housing 200, and the display unit 100 can be configured as a flexible display.

[0045] Furthermore, this disclosure provides an apparatus for unfolding a display unit 100, wherein a central portion 13 is driven to change: the degree of unfolding of the display unit 100, the angle formed by the display unit 100 and the shock-absorbing pad 10, and the distance between the display unit 100 and a user sitting in a vehicle seat.

[0046] Additionally, the device includes a rotating unit for rotating the housing 200 to tilt the display unit 100. Therefore, the display unit 100 can rotate in the front-to-back direction.

[0047] Figure 1 This is a perspective view of the shock-absorbing pad 10, where the device for unfolding the display unit 100 according to an embodiment of the present disclosure is located.

[0048] As shown in the figure, the shock absorber 10 includes an upper portion 11, a lower portion 12, and a central portion 13 located in the height direction between the upper portion 11 and the lower portion 12. The shock absorber 10 also includes a housing 200 that houses a display unit 100 configured to project upward from the central portion 13. The shock absorber 10 also includes a front bulkhead beam 300 located within the central portion 13 to extend in the vehicle width direction, and the front bulkhead beam is connected to side brackets 400 at both ends.

[0049] The housing 200 is located on the front bulkhead crossbeam 300. A connecting portion 320 is disposed between the housing 200 and the front bulkhead crossbeam 300, allowing the housing 200 to rotate relative to the front bulkhead crossbeam 300 in the longitudinal direction. When the rotational force of the rotating unit is transmitted to the connecting portion, the connecting portion 320 enables the housing 200 to move independently relative to the front bulkhead crossbeam 300. The housing 200 can be configured to rotate relative to the front bulkhead crossbeam 300 in the longitudinal direction.

[0050] The front bulkhead beam 300 may include an outer surface having a flat portion, such that the connecting portion 320 engages with the front bulkhead beam. The connecting portion 320 may be secured to the front bulkhead beam 300. A housing 200 is located on the outer surface of the connecting portion 320, and the housing is configured to rotate about the central axis of the front bulkhead beam 300 along the outer surface of the connecting portion 320.

[0051] The center portion 13 is configured to pop out into the passenger compartment of the vehicle. A front bulkhead crossbeam 300, connected to the inner side of the center portion 13, moves along guide portions 420 located at each of the side supports 400, so that the center portion 13, fixed to the front bulkhead crossbeam 300, moves in the longitudinal direction of the guide portions 420. The guide portions 420 can be shaped to be oriented in the longitudinal direction of the vehicle. The guide portions 420 can be shaped to be oriented at a predetermined angle relative to the horizontal plane of the vehicle body in the height direction.

[0052] The central portion 13 and the front bulkhead crossbeam 300 are moved integrally in the longitudinal direction of the guide portion 420 via the controller 500. When a user request or signal for switching to autonomous driving mode is received, the controller 500 controls the central portion 13 to move and insert into the space between the upper portion 11 and the lower portion 12.

[0053] The central portion 13 can protrude beyond the shock absorber 10 from the fully pulled-down position to the fully extended position. The central portion 13 can be positioned at a specific location between the fully pulled-down and fully extended positions. When a signal for switching to automatic driving mode is received, or when a user request is received in manual driving mode, the controller 500 can control the central portion 13 to move to the specific location between the fully pulled-down and fully extended positions.

[0054] According to an embodiment of this disclosure, when the driving mode received by the controller 500 is manual driving mode, the center portion 13 fully extends. When the driving mode received by the controller 500 is automatic driving mode, the center portion 13 is pulled down into the shock-absorbing pad 10 and stops at a position where the display can be fully extended.

[0055] Furthermore, when the user inputs a command to turn off the display unit 100 in the autopilot mode, the controller 500 controls the display unit 100 to roll into the housing 200, and the central portion 13 moves into the shock-absorbing pad 10 and stops at a position where the display can be fully pulled down.

[0056] The controller 500 is configured to independently or simultaneously control the extent of the display unit 100's unfolding and the tilt angle of the display unit 100, depending on the vehicle's driving mode. According to an embodiment, when the vehicle's driving mode is manual driving mode, the controller 500 can unfold the display unit 100 to a height below its maximum fully unfolded height and tilt the display unit 100 to a predetermined angle in the forward direction of the vehicle.

[0057] Conversely, when the vehicle's driving mode is autonomous driving mode, the controller 500 can fully extend the display unit 100 and tilt the display unit 100 in the rearward direction of the vehicle. Furthermore, in autonomous driving mode, the controller 500 can control at least a portion of the central portion 13 to be inserted into the space between the upper portion 11 and the lower portion 12.

[0058] The controller 500 can set the unfolding degree and tilt angle of the display unit 100 according to the vehicle's driving mode, the tilt angle of the seat back 21, and the rotation angle of the seat 20.

[0059] Additionally, the controller 500 can receive information about an external light source from a vision sensor located inside or outside the passenger compartment of the vehicle. The controller 500 can measure the angle at which light emitted from the external light source is introduced into the passenger compartment. Furthermore, the controller 500 can deploy or tilt the display unit 100 based on the information about the external light source transmitted from the vision sensor. In manual driving mode, the controller 500 can use the vision sensor to measure the amount of external light introduced into the passenger compartment and the angle of incidence of the external light, and can control the display unit 100 to tilt forward by 5 to 10 degrees.

[0060] As described above, the controller 500 can control at least one of the following: the unfolding degree of the display unit 100, the tilt angle of the display unit 100, or the position of the center portion 13, based on at least one of the vehicle's driving mode, the tilt angle of the seat back 21, or the rotation angle of the seat 20.

[0061] Figure 2a A cross-sectional view is shown of the front bulkhead beam 300 sliding along the guide portion 420 in the rearward direction of the vehicle with the center portion 13 fully extended. Figure 2b The diagram shows a cross-sectional view of the front bulkhead beam 300 sliding along the guide portion 420 in the forward direction of the vehicle and with the central portion 13 fully pulled down.

[0062] In other words, the central portion 13 can move between a fully pulled-down position and a fully popped-out position depending on the movement of the front bulkhead beam 300 along the guide portion 420, which is located at each of the side brackets 400 mounted to the vehicle body.

[0063] According to an embodiment of this disclosure, when the display unit 100 is fully deployed, the controller 500 can control the housing 200 to tilt to a predetermined angle in the rearward direction of the vehicle, and at least a portion of the central portion 13 is inserted into the shock absorber 10. Further, upon receiving a signal for switching to manual driving mode or upon user request, the controller 500 controls the drive unit 310 to fully eject the central portion 13.

[0064] According to another embodiment of this disclosure, the controller 500 is configured to independently set the degree of expansion of the display unit 100 and the tilt angle of the display unit 100 based on the state of the central portion 13.

[0065] Figure 3 A housing 200 located on a front bulkhead beam 300 according to an embodiment of the present disclosure is shown, as well as side brackets 400 connected to the two ends of the front bulkhead beam 300.

[0066] The housing 200 is located in the middle portion of the front bulkhead beam 300 and surrounds the outer surface of the front bulkhead beam 300. The housing 200 can be configured to connect to the outer surface of a connecting portion 320, which is located on the outer surface of the front bulkhead beam 300. The housing 200 rotates longitudinally along the connecting portion 320 about the center of the front bulkhead beam 300. When the housing 200 rotates, the display unit 100, which extends upward from the housing 200, rotates integrally with the housing 200.

[0067] The two ends of the front bulkhead crossbeam 300 are connected to the side brackets 400 fixed to the vehicle body. Drive units 310 are disposed between the two ends of the front bulkhead crossbeam 300 and the side brackets 400. Each of the drive units 310 may surround at least a portion of the front bulkhead crossbeam 300.

[0068] The drive unit 310 is configured such that one surface of it surrounds at least a portion of the end of the front bulkhead beam 300 and its opposing surface faces the side bracket 400. The side bracket 400 is provided with a guide portion 420 to which at least a portion of the drive unit 310 is coupled. The guide portion 420 may include a raised flat surface, and the drive unit 310 can be inserted into the space between the upper surface of the side bracket 400 and the raised flat surface of the guide portion 420.

[0069] The drive unit 310 includes a rack portion 311 formed generally parallel to the guide portion 420. The drive unit 310 receives driving force from the drive portion 410, which is disposed at the side bracket 400, to move the front bulkhead beam 300 in the longitudinal direction of the guide portion 420.

[0070] The controller 500 controls the driving force of the drive unit 410 to control the movement of the rack portion 311 in the longitudinal direction. The rack portion 311 is integrally formed with the drive unit 310. The degree to which the center portion 13 protrudes upward from the shock absorber 10 is set by the degree of drive of the drive unit 410.

[0071] Figure 4 The drive unit 310 and the front bulkhead beam 300 are shown, which are connected to the side bracket 400. Figure 5 The configuration of the side bracket 400, the front bulkhead beam 300, and the drive unit 310 is shown.

[0072] The rack portion 311 engages gearedly with the drive portion 410 fixed to the side bracket 400 so that the rack portion can move by the driving force of the drive portion 410. Further, at least a portion of the drive unit 310 is inserted into the side bracket 400 including the guide portion 420, so that the drive unit 310 can move in the longitudinal direction of the guide portion 420.

[0073] The drive unit 310 may include a slot 312 formed therein to allow the raised, flat surface of the guide portion 420 to be inserted into the slot. When a rotational force is applied to the drive unit 310, the slot 312 moves along the guide portion 420. Therefore, the front bulkhead beam 300 and the drive unit 310 move integrally in the longitudinal direction of the guide portion 420.

[0074] The guide portion 420 can be oriented in the longitudinal direction of the vehicle. The guide portion 420 can be oriented at a predetermined angle relative to the longitudinal direction of the vehicle. The shape of the guide portion 420 can be set according to the position of the center portion 13 and the height reached by the center portion 13 after popping out. The rack portion 311 moves along the guide portion 420. Therefore, according to the movement of the rack portion 311 in the longitudinal direction of the guide portion 420, the front bulkhead crossbeam 300, which is connected to the drive unit 310 including the rack portion 311, moves integrally with the center portion 13.

[0075] With the front end of the rack portion 311 engaged with the drive portion 410, the center portion 13 remains fully extended into the passenger compartment of the vehicle. With the rear end of the rack portion 311 engaged with the drive portion 410, the center portion 13 remains fully pulled down into the shock absorber 10.

[0076] Thus, the degree to which the central portion 13 protrudes from the front surface of the shock absorber 10 is determined by the degree to which the drive portion 410 is driven and the engagement position between the rack portion 311 and the drive portion 410.

[0077] Figure 6 The configuration of the rotating unit is shown, which is configured to rotate the housing 200 in the longitudinal direction of the vehicle, the housing being connected to the front bulkhead crossbeam 300.

[0078] The housing 200 is coupled to at least a portion of the front bulkhead beam 300. The housing 200 includes a winding portion (not shown) for winding a rollable display. The housing 200 includes an opening formed in its upper end to allow the display unit 100 to be deployed through the opening, and the housing includes a fastening portion 220 formed at its lower end to fasten to the front bulkhead beam 300. The fastening portion 220 is formed to surround a connecting portion 320 located on the outer surface of the front bulkhead beam 300, and the fastening portion is rotatable relative to the connecting portion 320.

[0079] The gear portion 330 may be fixedly disposed around the outer surface of the front bulkhead beam 300 at a position adjacent to the connecting portion 320. The housing 200 includes a rotating portion 210 disposed on its lower surface at a position adjacent to the front bulkhead beam 300 for engaging with the gear portion 330.

[0080] According to an embodiment of this disclosure, the rotating portion 210 can be implemented as a motor, and a gear can be connected to the rotating shaft of the motor. The gear connected to the rotating shaft of the motor meshes with a gear portion 330 fixed to the front bulkhead beam 300. Therefore, the housing 200 is capable of rotating about the central axis of the front bulkhead beam 300 in the longitudinal direction of the vehicle.

[0081] The connecting portion 320 is connected to the front bulkhead beam 300. The fastening portion 220 of the housing 200 is configured to surround the outer surface of the connecting portion 320 and is rotatable relative to the connecting portion 320. Therefore, when the driving force of the motor provided on the lower surface of the housing 200 is applied to the gear portion 330, the housing 200 rotates along the connecting portion 320.

[0082] According to embodiments of this disclosure, the housing 200 can rotate 5 degrees in the forward direction of the vehicle and 15 degrees in the rearward direction of the vehicle. The housing 200 can rotate freely within an area that does not cause the upper portion 11 of the shock absorber 10 and the display unit 100 to interfere with each other. Furthermore, the degree of rotation of the housing 200 can be automatically controlled by the controller 500 based on the following conditions: the tilt angle of the seat 20, the rotation angle (turning angle) of the seat 20 in the left-right direction, and the driving state of the vehicle.

[0083] The controller 500 receives information about the tilt angle of the seat 20 and controls the rotating part 210 based on the received information about the tilt angle of the seat 20, so that the housing 200 rotates corresponding to the angle of the seat back 21 of the seat 20. Further, the controller 500 receives information about the rotation angle of the seat 20 and controls the rotating part 210 of the housing 200, so that the display unit 100 is vertically oriented in the height direction of the vehicle.

[0084] Furthermore, when the central portion 13 moves to a position near the fully pulled-down position via the sliding movement of the front bulkhead beam 300 along the guide portion 420, the controller 500 rotates the housing 200 to a predetermined angle so that the display unit 100 does not interfere with the upper portion 11 of the shock-absorbing pad 10.

[0085] Figure 7a The tilt angle of the display unit 100 is shown in the manual driving mode of the vehicle.

[0086] In manual driving mode, the display unit 100 needs to be tilted to a predetermined angle in the forward direction of the vehicle to ensure the user's line of sight. For this purpose, the controller 500 rotates the housing 200 so that the display unit 100 is tilted 5 degrees in the forward direction of the vehicle.

[0087] In other words, when the vehicle's driving mode is switched to manual driving mode, the controller 500 tilts the display unit 100 in the forward direction of the vehicle so that the display unit 100, which extends upward from the housing 200, does not obstruct the user's view. Therefore, the display unit 100 is positioned at a predetermined angle tilted below the user's field of vision at the front of the vehicle.

[0088] Figure 7bThe tilt angle of the display unit 100 is shown when the vehicle is driving in autonomous driving mode or when the tilt angle of the seat 20 exceeds the reference angle set by the controller 500.

[0089] As shown in the figure, when a signal for switching to autonomous driving mode is received, or when the tilt angle of the seat 20 exceeds a set reference angle, the controller 500 controls the display unit 100 to tilt to its maximum extent in the rearward direction of the vehicle, substantially corresponding to the tilt angle of the seat back 21. In other words, when the vehicle is driving in autonomous driving mode, or when the seat 20 is tilted to an angle greater than set by the controller 500, the controller 500 controls the rotating part 210 to tilt the housing 200 to its maximum extent in the rearward direction of the vehicle, causing the front surface of the display unit 100 to be tilted downward. Therefore, the position of the display unit 100 is changed so that its front surface enters the user's field of vision.

[0090] When the seat 20 tilts at an angle exceeding the set reference angle (relaxation mode) in the vehicle's autonomous driving mode, the controller 500 can control the display unit 100 to fully unfold and control the drive unit 410 to fully pull down the center part 13.

[0091] In this way, in the relaxation mode, the controller 500 controls the degree of unfolding and the tilt angle of the display unit 100 to increase the convenience of the driver, and controls the drive unit 410 to pull the center unit 13 down completely, thereby increasing the interior space in the vehicle.

[0092] Figure 7c This is a side view showing the angle at which the display unit 100 unfolds under the rotational dynamics of the seat 20.

[0093] When the seat 20 rotates (i.e., rotates in the left-right direction) so that the driver can see the passenger sitting in the front seat, the controller 500 determines that the seat 20 is in a rotating state and controls it so that the display unit 100 is fully vertically unfolded in the height direction of the vehicle.

[0094] This state can be used as a dialogue mode that enables conversation between occupants sitting in the front seats. At this time, the display unit 100 is fully extended, allowing occupants to share the screen of the display unit 100. In other words, the display unit 100 and the central portion 13 are controlled so that the display unit 100 is fully vertically extended in the vehicle's height direction, so that occupants sitting in the front and rear seats can share the image displayed on the display unit 100.

[0095] In an embodiment of this disclosure, when the seat 20 is rotated in the left-right direction to an angle greater than a first set angle, the controller controls the display unit 100 to fully unfold from the housing and stand upright in the height direction of the vehicle.

[0096] Conversely, when the seat 20 rotates in the left-right direction to an angle less than or equal to the first preset angle, the controller causes the display unit 100 to be pulled into the housing and its center portion inserted into the shock-absorbing pad. As an example of this disclosure, the first preset angle can be set as a rotation angle of 90 degrees to the left and right relative to the center portion of the seat. The first preset angle can be set differently depending on the angle at which the seat can rotate.

[0097] It should be apparent from the above description that this disclosure provides the following effects through the above embodiments and through the configurations, combinations and usage relationships described above.

[0098] The device for unfolding the display unit according to the present disclosure controls the tilt angle of the display unit according to the driving state of the vehicle, thereby providing the most suitable field of view for the user who intends to view the information displayed on the display unit.
