Description

Technical Field

[0001] The present invention relates to a display device, and more particularly to a pop-up display device that protrudes when needed. Background Art

[0002] Vehicles include various input units and output units as user interface devices. As input units, vehicles have previously mainly used mechanical input units such as buttons, dials, and levers, but in recent years, there has been a growing trend for vehicles to adopt input units that allow users to input more intuitively, such as voice input units, touch input units, and even gesture input units.

[0003] As an output unit, the most basic output unit is an instrument panel that provides information such as vehicle speed, RPM (Revolutions Per Minute) and fuel level. However, as display technology improves and vehicle functions become more precise, the number of vehicles that include display units for outputting various contents is gradually increasing.

[0004] In the past, only small liquid crystals were used for sound output, but in recent years, large displays for navigation and vehicle status have been applied to the center instrument panel between the driver's seat and the front passenger seat. Furthermore, the instruments on the instrument panel no longer use pointers, but use displays to provide various information.

[0005] Furthermore, HUDs (head up displays) that are output on the front windshield so that the user can see important information without looking away have become common, and the driver can check the speed or navigation guidance while looking forward.

[0006] The display can not only output information but also implement touch input at the same time by providing a touch sensor, so that it can simultaneously function as an output unit and an input unit, and the size of the display applied to the vehicle is gradually increasing.

[0007] However, since the instrument panel including the instrument panel and the center instrument panel is located at the front of the vehicle, there is a problem that the front view is blocked as the size of the instrument panel becomes larger. In addition, in recent years, as the autonomous driving function becomes more advanced, the function of the instrument panel that provides information to the user during autonomous driving has become unnecessary or weakened, so the instrument panel is not necessarily the larger the better. Summary of the invention

[0045] Figure 1 FIG. 1 is a diagram showing a state where the display device 100 according to the embodiment of the present invention is installed as an instrument panel of a vehicle.

[0046] The display device 100 of the present invention can be installed in a vehicle and located on a dashboard in the front of the vehicle. The display device 100 is not limited thereto, and can be located in the rear seat or side of the vehicle. The display device 100 can be configured not only in a vehicle, but also in a non-mobile device.

[0047] However, in order to maximize the practicality in the limited space of the vehicle, a display device 100 that can be introduced and removed and change the area according to the needs is required. Therefore, the following is a display device 100 installed in a vehicle, especially, Figure 1 As shown, the description will be given based on the display device 100 installed as an instrument panel located on an instrument panel.

[0048] The vehicle equipped with the display device 100 may be an autonomous driving vehicle. The vehicle may be switched to an autonomous driving mode or a manual driving mode based on user input. For example, the vehicle may be switched from a manual driving mode to an autonomous driving mode, or from an autonomous driving mode to a manual driving mode, based on user input received through a user interface device.

[0049] The vehicle may be switched to an automatic driving mode or a manual driving mode based on the driving situation information. The driving situation information may include at least one of object information outside the vehicle, navigation information, and vehicle state information.

[0050] When the vehicle is driven in the autonomous driving mode, the autonomous driving vehicle may be driven according to the driving system. For example, the autonomous driving vehicle may be driven based on information, data or signals generated in the driving system, the departure system and the parking system.

[0051] When the vehicle is traveling in the manual driving mode, the autonomous driving vehicle may receive user input for driving through the driving operation device. The vehicle may travel based on the user input received through the driving operation device.

[0052] The information provided varies according to the driving mode of the vehicle, and the size of the display unit can vary according to the information provided. The present invention can provide a display device 100 with a wider screen as needed while ensuring a sense of openness in the front by equipping the vehicle with a display device 100 whose size can be changed according to the situation.

[0053] The display device 100 of the present invention may include: a display panel 110 introduced through an opening 15 formed on a dashboard 10 ; and a driving unit 130 driving the display panel 110 to move in a vertical direction.

[0054] Although the description is based on a form in which the display panel 110 is led out from the bottom to the upper side, the display panel 110 may be led out in the horizontal direction or may be led out from the upper side to the lower side.

[0055] However, when considering the installation space of the driving unit 130 and the space for accommodating the display panel 110 in the front of the vehicle, it is possible to Figure 1 As shown, an opening portion 15 is formed on the instrument panel 10 , and a storage space for the driving unit 130 and the display panel 110 can be configured at the lower portion of the instrument panel 10 .

[0056] Figure 1 (a) is the first state, Figure 1 (b) is the second state. In the first state, the upper portion of the display panel 110 is partially exposed, and the display panel 110 moves upward and is converted to the second state. In the second state, the display panel 110 is exposed upward to its lower portion and expanded to the maximum screen.

[0057] The display panel 110 may display graphic objects corresponding to various information. The display panel 110 may include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, a three-dimensional graphic display (3D display), and an electronic ink display (e-ink display).

[0058] The display panel 110 may form a layered structure or an integrated structure with the touch input portion 213 to implement a touch screen. The display panel 110 may include a transparent display. The transparent display may be attached to a windshield or a window.

[0059] Figure 2 yes Figure 1 The driving unit 130 located at the back of the display panel 110 may be located inside the instrument panel 10 .

[0060] like Figure 2 As shown, the instrument panel 10 can be composed of two layers, and can be constructed so that the part close to the driver is lower and the front is higher. The front instrument panel 10 and the rear instrument panel 10 can have steps, and the opening 15 for introducing and extracting the display panel 110 can be located between the first instrument panel 11 and the second instrument panel 12.

[0061] The second instrument panel 12 and the first instrument panel 11 located at the back of the display panel 110 have a step, and the fixing cover 120 located at the back of the display device 100 can be arranged to align the position of the second instrument panel 12 .

[0062] The fixing cover 120 may cover the driving part 130 that drives the display panel 110 in the up-down direction, and may fix the components (the motor 131 , the pinion gear, etc.) of the driving part 130 that are fixed and do not move.

[0063] The driving unit 130 may be installed inside the instrument panel 10 and partially protrude toward the upper side of the opening 15 , but the area covered by the second instrument panel 12 or exposed is small.

[0064] Figure 2 (a) shows a first state (AA cross-sectional view), and since in the first state, the back side of the display portion protruding upward from the second instrument panel does not have the fixed cover 120 or the driving unit 130, the display device 100 can have a slim appearance.

[0065] Figure 2 (b) shows a second state (BB cross-sectional view). When switching to the second state, the display panel 110 moves upward. In order to cover the structure of the driving unit 130 (rack 137) fixed to the back side of the display panel 110, in the second state, the fixing cover 120 can be located on the upper side than the lower end of the display panel 110.

[0066] The height of the fixed cover 120 in the vertical direction needs to be set to be greater than the moving distance of the display panel 110 and the length of the rack 137. The relevant content will be described in detail later. Figure 7 Please explain specifically when necessary.

[0067] Figure 3 1 is a rear perspective view of the display device 100 according to the embodiment of the present invention. A shows a position corresponding to the top surface of the first instrument panel 11, B shows a position corresponding to the top surface of the second instrument panel 12, the upper side of A is a portion for viewing by a user sitting in a vehicle seat, and the upper portion of B is a portion visible when viewing the display device 100 from the back (front of the vehicle).

[0068] If the thickness of the display device 100 exposed to the upper portion of the large instrument panel 10 is thick, it becomes bulky and is not preferable from a design point of view. The present invention aims to improve the structure of the driving part 130 that moves the display panel 110 to reduce the size of the fixing cover 120.

[0069] Figure 4 FIG. 1 is a diagram showing the driving unit 130 of the display device 100 according to the embodiment of the present invention. Figure 4 Shown in Figure 3 State (a) is a diagram showing that the driving unit 130 is located on the back side of the display panel 110 in a state where the fixing cover 120 is removed.

[0070] The driving part 130 may be composed of a motor 131 providing a rotational force, a pinion gear receiving the rotational force of the motor 131 and rotating, and a rack gear 137 that linearly moves when the pinion gear rotates by meshing with the pinion gear.

[0071] The display panel 110 of the present invention can be formed long in the horizontal direction, and a pair of racks 137 can be provided on the left and right so that the display panel 110 moves without twisting. In order to transmit the force of one motor 131 to both sides, a horizontal shaft 134 extending long in the horizontal direction can be used.

[0072] Since the horizontal axis 134 extends in the horizontal direction, the motor 131 can also be configured to rotate with the horizontal direction as the axis. However, gravity will apply a load to the axis when rotating, such as Figure 4 As shown, the axis of the motor 131 can be arranged in the vertical direction, and the force rotating about the vertical direction as the axis can be converted into the force rotating about the horizontal direction as the axis.

[0073] Figure 5 1 is an enlarged view showing a portion of the motor 131, which may include a worm gear 132 coupled to the shaft of the motor 131 and a helical gear 133 that rotates in mesh with the worm gear 132. The worm gear 132 is in the shape of a rod having a threaded outer peripheral surface, and the gear that rotates in mesh with the worm gear 132 may rotate around an axis that is in a different direction (usually a vertical direction) from the rotation axis of the worm gear 132.

[0074] Therefore, unlike the worm gear 132 arranged in the vertical direction, the rotation axis of the helical gear 133 extends in the horizontal direction.

[0075] The gear meshing with the worm gear 132 may be a spur gear, but in this embodiment, a helical gear 133 is used. The helical gear 133 has twisted teeth and has a better meshing effect than a spur gear, thereby reducing noise and facilitating force transmission.

[0076] like Figure 4 As shown, the number of revolutions of the horizontal shaft 134 relative to the number of revolutions of the motor 131 may be adjusted by providing a plurality of gears.

[0077] The horizontal shaft 134 extends in the left-right direction, and a pair of gear modules are located at the left and right ends of the horizontal shaft 134. Since the gear modules have a left-right symmetrical structure, the gear modules on one side are used as a reference for description.

[0078] Figure 6 1 is a diagram showing the pinion module 135 of the display device 100 according to an embodiment of the present invention. Figure 6 As shown, the pinion module 135 of the present invention may include a plurality of pinions 1351, 1352, 1353, and the horizontal shaft 134 may be connected to one of the plurality of pinions 1351, 1352, 1353 to transmit rotational force.

[0079] In this embodiment, the horizontal shaft 134 is connected to the second pinion 1352 located at the upper side, and the first pinion 1351 is located at the lower side below the second pinion 1352. In order to transmit the rotational force of the second pinion 1352 to the first pinion 1351, a third pinion 1353 located between the first pinion 1351 and the second pinion 1352 may also be included.

[0080] The horizontal shaft 134 may also be combined with the first pinion gear 1351 or the third pinion gear 1353 .

[0081] The first pinion gear 1351 and the second pinion gear 1352 are located at the same position in the horizontal direction and are spaced apart in the up-down direction, and the third pinion gear 1353 may be located between the first pinion gear 1351 and the second pinion gear 1352 .

[0082] like Figure 6 As shown in (b), the rotation direction of the third pinion 1353 is different from the rotation direction of the first pinion 1351 and the second pinion 1352. That is, since the vertical movement of the rack 137 can be restricted when the third pinion 1353 contacts the rack 137, the third pinion 1353 can be located slightly closer to the back direction than the first pinion 1351 or the second pinion 1352 in a manner that does not contact the rack 137.

[0083] Figure 7 1 and 2 are diagrams showing the positions of the pinion and the rack 137 in the first state and the second state of the display device 100 according to the embodiment of the present invention. Figure 7 (a) shows a first state, in which the rack 137 is meshed with the first pinion 1351. Figure 7 (b) shows the second state, where the rack 137 is meshed with the second pinion 1352 .

[0084] When switching from the first state to the second state, the rack 137 switches from being meshed with the first pinion 1351 to being meshed with both the first pinion 1351 and the second pinion 1352 , and finally ends up being meshed with only the second pinion 1352 and switches to the second state.

[0085] Since the rack 137 can be driven as long as it is kept in meshing with one of the first pinion 1351 and the second pinion 1352, in the first state, the upper end of the rack 137 is kept in meshing with the first pinion 1351, and in the second state, the lower end of the rack 137 is kept in meshing with the second pinion 1352. Therefore, the length r1 of the rack 137 is shorter than the moving distance d.

[0086] on the other hand, Figure 81 is a diagram showing the driving unit 130 when there is only one pinion gear. Since the rack 137 needs to remain in meshing with one pinion gear in both the first state and the second state, it needs to move a length r2 greater than the distance d. That is, it is necessary to add the length of the rack 137 corresponding to the length of the space meshing with the pinion gear to the moving distance.

[0087] If the length of the rack 137 is increased, the length of the space occupied by the rack 137 on the back of the display panel 110 will be increased. Since the fixing cover 120 needs to have a height that can cover the rack 137 even in the second state, Figure 7 As shown, in the case of using a plurality of pinions, the height c1 of the fixed cover 120 may be shorter than Figure 8 The height c2 of the fixed cover 120 in the embodiment.

[0088] Fig. 9 1 is a side view showing the position of the fixing cover 120 according to the number of pinion gears. Fig. 9 (a) is Figure 7 The embodiment shown includes a plurality of pinions, Fig. 9 (b) is Figure 8 An embodiment including a pinion is shown.

[0089] If the length of the rack 137 is shorter, then Fig. 9 As shown in (a) of FIG. 9 , the height of the fixing cover 120 is also reduced, and the fixing cover 120 does not protrude from the second instrument panel 12. On the other hand, as shown in (b) of FIG. 9 , if the length of the rack 137 is longer, Fig. 9 As shown in (b), the rack 137 will protrude to the upper side of the second instrument panel 12, and the height of the fixing cover 120 needs to be increased. When viewed from the side, the fixing cover 120 has a heavy appearance.

[0090] Although the above-mentioned embodiment is described based on the embodiment in which two pinions are meshed with the rack 137, more than two pinions may be used, thereby obtaining a longer driving distance using a shorter rack 137.

[0091] Reference Figure 4 , a guide rail 1381 and a guide block 1382 for guiding the movement in the vertical direction may be additionally included.

[0092] The guide rail 1381 may be coupled to the fixing cover 120 , and the guide block 1382 may be coupled to the rear surface of the display panel 110 and move in the up-down direction along the guide rail 1381 .

[0093] If only the rack 137 and the pinion are used, distortion may occur, such as Figure 4As shown, the guide rail 1381 and the guide block 1382 can be used to stably and shake-free move in the vertical direction.

[0094] Additional, such as Figure 3 As shown, the driving in the vertical direction is assisted by forming a long groove in the fixing cover 120 itself and forming a guide protrusion 1383 inserted into the groove on the back of the display panel 110.

[0095] As described above, the display device 100 of the present invention can reduce the size of the fixing cover 120 by reducing the height of the driving part 130 structure at the rear side.

[0096] In particular, it is possible to ensure a frontal view and provide a sense of openness by changing the size of an instrument panel applied to a vehicle.

[0097] The detailed description should not be interpreted as limiting in all aspects, but should be considered as illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
