Figure 2 FIG. is a perspective view of a display device 200 according to an embodiment of the present disclosure. Figure 3 FIG. is a schematic diagram for explaining a method of identifying the position of a driver-specific face in the display device 200 according to an embodiment of the present disclosure.

[0045] Hereinafter, when describing the display device 200 according to an embodiment of the present disclosure, it is assumed that the front-rear direction is the x-axis direction, the left-right direction is the y-axis direction, and the up-down direction is the z-axis direction.

[0046] Figure 1 FIG. is a schematic diagram showing a vehicle 100 according to an embodiment of the present disclosure. Specifically, Figure 1 the front of the driver's seat and the front passenger seat inside the vehicle 100 is shown.

[0047] As Figure 1 shown, the display device 200 can be installed on the mounting portion 120 located on the vehicle body 110. The mounting portion 120 can include an instrument panel, which is located in front of the driver's seat and the front passenger seat. In addition, the display device 200 can include a front display 210, which is located in front of the driver's seat and the front passenger seat of the vehicle 100. As Figure 2 shown, the display device 200 can include a driving module 220, which is used to adjust the height of the front display 210.

[0048] In addition, the steering wheel 130 can be located in front of the driver's seat. The steering wheel 130 installed on the vehicle 100 according to an embodiment of the present disclosure can include a D-shaped steering wheel 130 to ensure a better view for the driver towards the front display 210. The camera 140 can be located on the top of the mounting portion 120 or the vehicle body 110.

[0049] The camera 140 mounted on the vehicle 100 can function to identify the position of a specific face of the driver. The driving module 220 is connected to the camera 140 and is configured to adjust the height of the front display 210 according to the position of the specific face of the driver.

[0050] Reference Figure 3 , the display device 200 according to an embodiment of the present disclosure can identify the position of a specific face (e.g., eyes or nose) of the driver 10 through the camera 140. In one embodiment, when the driver 10 is sitting on the seat, the position of the specific face of the driver 10 can be identified within the Figure 3 range shown.

[0051] In addition, in the vehicle 100 according to an embodiment of the present disclosure, in response to the expansion of the display device 200 and the adjustment of the height of the front display 210, a passenger airbag 150 can be installed in the upper front part of the passenger seat, which will be described later. Therefore, the present disclosure can improve the safety of passengers and provide a display device 200 customized for passengers.

[0052] Figure 2 is a perspective view of the display device 200 according to an embodiment of the present disclosure.

[0053] The display device 200 according to an embodiment of the present disclosure may include a driving module 220 that is connected to the front display 210 and the camera 140 and is configured to adjust the height of the front display 210 according to the position of the specific face of the driver. The front display 210 is located in front of the driver's seat and the passenger seat of the vehicle 100, and the camera 140 is mounted on the vehicle 100. The driving module 220 can provide a driving force to the front display 210 to cause the front display 210 to rotate and move along a curved path.

[0054] The support frame 211 can be connected to the rear surface of the front display 210. The driving module 220 may include a link member 211 that is rotatably coupled to the support frame 211. The driving module 220 may include a ball screw member 222 that is connected to the link member 221, moves linearly, and rotates the link member 221.

[0055] The support frame 211 may include a first rotation protrusion 2111 formed on one side thereof and a second rotation protrusion 2112 formed on the other side thereof. The link member 221 may include: a first link 2211, the first rotation protrusion 2111 is inserted into the first link 2211 on one side thereof; and a second link 2212, the second rotation protrusion 2112 is inserted into the second link 2212 on one side thereof. Specifically, the first link 2211 may include a first guide groove 2211a formed longitudinally.

[0056] The driving module 220 may include a fixing bracket 223 which is formed to rotatably connect the other sides of the first link 2211 and the second link 2212. The fixing bracket 223 may include a guiding plate 2231 into which the first rotating protrusion 2111 is inserted. Specifically, the guiding plate 2231 may include a second guiding groove 2231a which is formed to guide the curved movement of the supporting frame 211.

[0057] The driving module 220 may include a rotating plate 225. The rotating plate 225 is formed by extending from the rotating shaft 224 coupled to the other side of the first link 2211 and the outer peripheral surface of the rotating shaft 224. In addition, the rotating plate 225 is coupled to the ball screw member 222. The second rotating shaft 228 may be coupled to the other side of the second link 2212. Accordingly, the pair of link members 221 may rotate simultaneously with the rotating shaft 224.

[0058] The ball screw member 222 may include a driving motor 2221, a ball screw bolt 2222, and a ball screw nut 2223. The ball screw bolt 2222 rotates under the drive of the driving motor 2221, and the ball screw nut 2223 linearly moves due to the rotation of the ball screw bolt 2222. In this case, the rotating plate 225 may be rotatably coupled to the ball screw nut 2223. Accordingly, as the ball screw nut 2223 moves linearly, the rotating plate 225 may rotate with the rotating shaft 224, enabling the first link 2211 to rotate.

[0059] In addition, the display device 200 according to an embodiment of the present disclosure may include a position detection sensor 226 which detects the height of the front display 210. The driving module 220 may include a detection plate 227 which extends from the outer peripheral surface of the rotating shaft 224 at a position corresponding to the position detection sensor 226.

[0060] The operation method of the components included in the display device 200 according to an embodiment of the present disclosure will be described in more detail below.

[0061] Figures 4 to 7 It is a schematic diagram for explaining a method of adjusting the height of the front display 210 in the display device 200 according to an embodiment of the present disclosure. Figure 8 It is a schematic diagram for explaining a method of detecting the height of the front display 210 through the position detection sensor 226 in the display device 200 according to an embodiment of the present disclosure.

[0062] Specifically, Figures 4 to 7 It shows that the height of the front display 210 is adjusted through the operation of the driving module 220 and the height of the front display 210 changes from the lowest point to the highest point.

[0063] Figure 4 shows a situation where the height of the front display 210 is at the lowest point, in which case the forward view of the driver or passenger can be maximized. In this state, the height of the front display 210 can be adjusted according to the position of the specific face of the driver through the camera 140 in the above Figure 3 .

[0064] Specifically, the ball screw bolt 2222 can rotate according to the operation of the drive motor 2221. The ball screw nut 2223 can linearly move according to the rotation of the ball screw bolt 2222. The rotating plate 225 extending from the outer peripheral surface of the rotating shaft 224 can be rotatably coupled to one side of the ball screw nut 2223. Therefore, when the ball screw nut 2223 linearly moves, the rotating plate 225 can rotate together with the rotating shaft 224.

[0065] The support frame 211 coupled to the rear surface of the front display 210 can be rotatably coupled to one side of the first link 2211. The rotating shaft 224 can be coupled to the other side of the first link 2211. In addition, the other side of the first link 2211 can be rotatably coupled to the fixed bracket 223.

[0066] The first rotation protrusion 2111 formed on one side of the support frame 211 can be inserted into the first guide groove 2211a formed on the first link 2211. The fixed bracket 223 can include a guide plate 2231, and the first rotation protrusion 2111 is inserted into the guide plate 2231.

[0067] A second rotation protrusion 2112 can be formed on the other side of the support frame 211. The second rotation protrusion 2112 can be inserted into one side of the second link 2212. The other side of the second link 2212 can be rotatably coupled to the fixed bracket 223.

[0068] Specifically, the first link 2211 can include a first guide groove 2211a longitudinally formed on one side thereof. The first rotation protrusion 2111 can be inserted into the first guide groove 2211a. The guide plate 2231 can include a second guide groove 2231a having a curved shape. The first rotation protrusion 2111 is inserted into the second guide groove 2231a.

[0069] Therefore, both the rotation of the ball screw bolt 2222 and the linear movement of the ball screw nut 2223 are driven by the drive motor 2221. The rotation of the ball screw bolt 2222 and the linear movement of the ball screw nut 2223 can rotate the first link 2211 and the second link 2212, enabling the support frame 211 to move, thereby adjusting the height of the front display 210.

[0070] Specifically, as described above, while the front display 210 moves, the front display 210 also needs to rotate to align with the position of the driver's specific face. In other words, in order to align with the position of the driver's specific face, Figures 4 to 7 the shown angles θ1, θ2, θ3, and θ4 may all be different. The angles θ1, θ2, θ3, and θ4 may be associated with the movement of the ball screw nut 2223.

[0071] In addition, due to the structure in which the front display 210 is inserted and installed in the installation part 120 of the vehicle 100 described above, when the front display 210 moves, it is necessary to protect the front lower part of the front display 210.

[0072] To this end, the display device 200 according to an embodiment of the present disclosure can rotate the front display 210 and move it along a curved path during the movement of the front display 210. This can be achieved through the second guide groove 2231a formed in a curved shape on the guide plate 2231 and the first guide groove 2211a longitudinally formed at one end of the first link 2211.

[0073] That is, the first rotation protrusion 2111 formed on the support frame 211 can be inserted into the first guide groove 2211a and the second guide groove 2231a, so that the support frame 211 can rotate and move along a curved path when the first link 2211 rotates.

[0074] Therefore, in the display device 200 according to an embodiment of the present disclosure, the driving module 220 can adjust the height of the front display 210 through a four-bar linkage structure including four rotation points formed on the first link 2211, the second link 2212, and the support frame 211.

[0075] In addition, the front display 210 can rotate and move along a curved path to align with the driver's specific face and protect the front lower part of the front display 210.

[0076] Refer to Figure 8 , in the display device 200 according to an embodiment of the present disclosure, the driving module 220 may include a position detection sensor 226 for detecting the height of the front display 210.

[0077] In one embodiment, the position detection sensor 226 may be located at the top of the fixed bracket 223. The driving module 220 may include a detection plate 227 extending from the outer peripheral surface of the rotating shaft 224 at a position corresponding to the position detection sensor 226. Therefore, the detection plate 227 can rotate together with the rotating shaft 224, and the position detection sensor 226 can detect the height of the front display 210 by detecting the position change depending on the rotation of the detection plate 227.

[0078] Figure 9 It is a schematic diagram for explaining a control method of a display device according to an embodiment of the present disclosure. Figure 10 and Figure 11 It is a schematic diagram for explaining various embodiments of a display device control method according to the present disclosure.

[0079] Based on the above, with reference to Figures 1 to 8 , a control method of a display device according to an embodiment of the present disclosure will be described.

[0080] In the control method of the display device according to an embodiment of the present disclosure, the position of a specific facial part of the driver can be recognized by a camera 140 installed on a vehicle 100 (S910). Then, the operation amount of a ball screw member 222 of a drive module 220 can be determined based on the recognized position of the specific facial part (S920). Here, the operation amount of the ball screw member 222 can refer to the moving amount of a ball screw nut 2223 when it moves linearly. Therefore, the rotation amount of a ball screw bolt 2222 by the operation of a drive motor 2221 can be determined.

[0081] Through the operation of the ball screw member 222 (S930), a link member 221 of the drive module 220 can rotate, thereby adjusting the height of a front display 210 (S940). Specifically, the control method of the display device according to an embodiment of the present disclosure can adjust the height of the front display 210 to align with the position of a specific facial part of the driver, and control the front display 210 to rotate and move along a curved path to protect the lower front part of the front display 210.

[0082] Figure 10 It is a schematic diagram for explaining another embodiment of a display device control method according to the present disclosure.

[0083] After adjusting the height of the front display 210 (S1010), information for requesting confirmation from the driver or passenger can be displayed (S1020). Information for requesting confirmation from the driver or passenger can be displayed on the screen of the front display 210, and the displayed information for requesting confirmation can include, for example, whether it is necessary to adjust the height of the front display 210 (as Figure 10 shown) (S1030).

[0084] If the driver or passenger determines that height adjustment is not required, the adjusted height of the front display 210 can be maintained. On the other hand, if the driver or passenger determines that height adjustment is required, an operation signal from the driver or passenger can be received (S1040). The operation signal from the driver or passenger can include, for example, adjusting the height of the front display 210 by touching the screen of the front display 210. In addition, based on the operation signal from the driver or passenger, the height of the front display 210 can be readjusted (S1050). Additionally, the display can be automatically adjusted by an operation signal based on the detection by the camera 140 of the position of a specific face of the driver or the front passenger.

[0085] Alternatively, the information displayed for requesting confirmation can include information for performing the steps (S1010) of adjusting the height of the front display 210. The driver or passenger can restart the height adjustment step (S1010) by touching the screen of the front display 210 again.

[0086] Figure 11 A schematic diagram for explaining another embodiment of the display device control method according to the present disclosure.

[0087] After identifying the position of a specific face of the driver by the camera 140 mounted on the vehicle 100 (S1110), the operation amount of the ball screw member 222 of the drive module 220 can be determined according to the identified position of the specific face (S1120). The ball screw member 222 can be operated accordingly (S1130).

[0088] In this case, the current load of the drive motor 2221 of the ball screw member 222 can be monitored (S1140), and it can be determined whether the monitored current load exceeds a reference value (S1150). This is because if the operation of the drive module 220 is obstructed by an obstacle, it may cause damage to the display device 200. If the monitored current load does not exceed the reference value, the operation of the ball screw member 222 can be continued, thereby allowing the height of the front display 210 to be adjusted (S1160).

[0089] On the other hand, if the monitored current load exceeds the reference value, that is, if the operation of the drive module 220 is obstructed by an obstacle, the front display 210 can return to the original position (S1170). Thereafter, information for requesting confirmation of the obstacle can be displayed (S1180). The information for requesting confirmation of the obstacle can be displayed on the screen of the front display 210. In addition, an operation signal from the driver or passenger can be received (S1190).

[0090] For example, an operation signal from a driver or a passenger can be received by touching the screen of the front display 210. After an obstacle that hinders the operation of the driving module 220 is removed, the driver or the passenger can send an operation signal by touching the screen of the front display 210 so that the driving module 220 can operate again. Thereafter, the display device control method can return to the step (S1110) of identifying the position of the specific face of the driver through the camera 140 mounted on the vehicle 100.

[0091] The present disclosure also includes a system for adjusting the position of a display device in a vehicle. The system includes: a front display 210 located in front of the driver's seat and the passenger's seat of the vehicle 100; a camera 140 configured to detect the position of the specific face of an occupant on the driver's seat or the passenger's seat; a driving module 220 communicatively coupled with the camera 140 and configured to provide a driving force to enable the front display 210 to move; and a controller (such as a processor) configured to control the driving module 220 to adjust the position of the front display 210 to provide an optimal viewing for the occupant. The movement of the front display 210 includes at least one of linear movement, rotational movement, and curvilinear path movement or any combination thereof.

[0092] In summary, according to the display device and its control method of the present disclosure, the height of the display can be adjusted according to the position of the specific face of the driver, thereby effectively providing various convenience information. In addition, according to the display device and its control method of the present disclosure, the movement and tilt of the display can be effectively controlled by a driving module including a ball screw member and a link member.

[0093] The above detailed description should not be construed as restrictive in all aspects, but rather as illustrative. The scope of the present disclosure should be determined by a reasonable interpretation of the technical solutions of the present disclosure, and all changes within the equivalent scope of the present disclosure are covered by the present disclosure.
