[0178] In embodiments of the present invention, the 'vehicle rear seat display device' is a display device positioned in the rear seat of a vehicle (100) and may be formed to be movable in different directions. The vehicle rear seat display device may have a plurality of driving modules for moving in different directions. In addition, the vehicle rear seat display device may be formed to be tiltable to have a predetermined angle with respect to the ceiling of the vehicle.

[0179] FIG. 2 is a drawing showing a vehicle rear seat display device (800) according to an embodiment of the present invention installed in a vehicle (100).

[0180] As illustrated in FIG. 2, the vehicle rear seat display device (800) may be formed such that a plurality of movable frames (840a, 840b) connected to a fixed frame (801) installed on the ceiling facing from the front seat (110) to the rear seat in the vehicle (100), and a first and second display (820a, 820) are respectively arranged on the front of the plurality of movable frames (840a, 840b).

[0181] Meanwhile, an angle adjustment unit (860) may be mounted on the back of a plurality of movable frames (840) to adjust the angle of the first and second displays (820a, 820b). Depending on the operation of the angle adjustment unit (860), the first and second displays (820a, 820) may be horizontal with respect to the fixed frame (801) or vertical as illustrated.

[0182] A plurality of movable frames (840) are formed to be movable in different directions. Accordingly, the first and second displays (820a, 820b) placed on the front of each of the plurality of movable frames (840) can move in different directions.

[0183] Specifically, a plurality of movable frames (840) can move along the longitudinal direction of a fixed frame (801) installed on the ceiling to the front of the front seat or to the rear of the front seat (or, the front of the rear seat). Accordingly, the first and second displays (820a, 820b) move to the front of the front seat of the vehicle (100) or to the front of the rear seat.

[0184] Additionally, multiple moving frames (840) can be moved to move closer to or further apart from each other. Accordingly, the spacing between the first and second displays (820a, 820b) is adjusted so that they move closer to (or come into contact with) or further apart from each other.

[0185] As a plurality of moving frames (840) move toward the front of the front seat, the first and second displays (820a, 820b) are positioned toward the front of the front seat of the vehicle (100), and the occupant of the front seat (driver and / or passenger) can receive content services through the first and second displays (820a, 820b).

[0186] Meanwhile, when a plurality of moving frames (840) are located behind the front seat as shown in FIG. 2, the passenger in the rear seat of the vehicle (100) can receive content services through the first and second displays (820a, 820b).

[0187] In addition, when the first and second displays (820a, 820b) are spaced apart from each other, the passenger in the rear seat of the vehicle (100) can receive content services through the first and second displays (820a, 820b) as independent screens. That is, the passenger on the left side of the rear seat can receive content services through the first display (820a), and the passenger on the right side of the rear seat can receive another content service through the second display (820b).

[0188] Meanwhile, when the distance between the first and second displays (820a, 820b) is adjusted to be close, the entire first and second displays (820a, 820b) can operate as a full screen. That is, when the first and second displays (820a, 820b) come close to each other and come into contact, they can be switched to a full screen without additional screen control.

[0189] In another embodiment, if it is determined that there is no intention to use the first and second displays (820a, 820b), folding may be performed so that a plurality of movable frames (840) form a horizontal line relative to the fixed frame (801) according to the operation of the angle adjustment unit (860).

[0190] The state in which a plurality of movable frames (840) shown in FIG. 2 form a vertical position with the fixed frame (801) is defined as the “unfolding state.” Additionally, although not shown, the state in which a plurality of movable frames (840) form a horizontal position with the fixed frame (801) is defined as the “folding state.”

[0191] Referring to FIG. 2, the portion connected to the fixed frame (801) in the plurality of movable frames (840) remains fixed, and the plurality of movable frames (840) can be switched from an "unfolding state" to a "folding state" by rotating significantly toward the fixed frame (801) in a bent manner until they form a horizontal line with the fixed frame (801).

[0192] In this way, the vehicle rear seat display device (800) according to an embodiment of the present invention is movable between the front seat and the rear seat, and the plurality of displays are movable to move closer to or further away from each other, so that all passengers in the vehicle (100) can receive content services through the rear seat display device (800).

[0193] FIG. 3 is a block diagram for explaining the detailed configuration of a vehicle rear seat display device (800) according to an embodiment of the present invention.

[0194] A vehicle rear seat display device (800) may comprise a communication unit (810), first and second displays (820a, 820b), first and second driving modules (830a, 830b), a plurality of moving frames (840), a control unit (850), an angle adjustment unit (860), and an input unit (870). Additionally, the vehicle rear seat display device (800) may be connected to communicate with a system within the vehicle (100) through the communication unit (810).

[0195] The communication unit (810) can receive vehicle data and vehicle driving data by communicating with the vehicle (100), the system within the vehicle (100), various sensors within the vehicle (100), and various devices such as ADAS (Advanced Driver Assistance Systems) and DMS (Driver Monitoring System).

[0196] Additionally, the communication unit (810) can receive an input signal corresponding to an input applied to an input device installed in the vehicle (100) and transmit it to the control unit (850). For example, the communication unit (810) can receive a signal related to the driving of at least one of the first and second driving modules (830a, 830b) of the rear seat display device (800) from an input device connected in the vehicle (100).

[0197] The display of the rear seat vehicle display device (800) is configured to include a first and second display (820a, 820b), each having a separate frame. The first and second displays (820a, 820b) may each display different screens, display the same screen, or display a single connected screen.

[0198] The first and second displays (820a, 820b) may be placed on the front of each of a plurality of movable frames (840) arranged side by side. In other words, the back of the first and second displays (820a, 820b) may be placed to be coupled to a movable frame formed to be movable. Accordingly, as the plurality of movable frames (840) move, the coupled first and second displays (820a, 820b) may also move together.

[0199] When the first and second displays (820a, 820b) are used as independent screens, the screens can be controlled independently of each. Also, when the first and second displays (820a, 820b) are used as full screens, a single integrated screen control can be performed.

[0200] In the embodiment, screen control of the first and second displays (820a, 820b) can be performed based on movement resulting from the driving of the first and second driving modules (830a, 830b). For example, if the first and second displays (820a, 820b) move toward the front or rear seat according to the driving of the first driving module (830a), the type of content displayed may change. Also, for example, if the first and second displays (820a, 820b) move closer to or further apart from each other according to the driving of the second driving module (830b), the screen mode of the display (e.g., full screen mode) may change.

[0201] The first and second driving modules (830a, 830b) provide driving force to move a plurality of moving frames (840) so that the first and second displays (820a, 820b) move in a first direction or in a second direction. Specifically, the first driving module (830a) can transmit driving force to a plurality of moving frames (840) so that the first and second displays (820a, 820b) move in a first direction, that is, in a direction toward the front seat or toward the rear seat together. In addition, the second driving module (830b) can provide driving force to a plurality of moving frames (840) so that the first and second displays (820a, 820b) move in a second direction, that is, in a direction toward each other or toward each other.

[0202] First and second displays (820a, 820b) are respectively arranged on the front of a plurality of movable frames (840). One side of the plurality of movable frames (840) is connected to one side of a fixed frame (801, FIG. 2) that connects the front and rear seats of the vehicle ceiling. Accordingly, when the first driving module (830a) is driven, the plurality of movable frames (840) can be operated to move along the longitudinal direction of the fixed frame (801).

[0203] A plurality of movable frames (840) may be arranged side by side with a predetermined spacing and formed to be supported by the same support frame located on the back. Accordingly, when the second driving module (830b) is driven, the plurality of movable frames (840) may move closer to each other or move again with a predetermined spacing while being supported by the same support frame.

[0204] The control unit (850) controls the overall operation of the vehicle rear seat display device (800). The control unit (850) may be named a processor or a PC and may be placed, for example, within a housing located between the front seats inside the vehicle (100).

[0205] The control unit (850) can control the driving of the first and second driving modules (830a, 830b) and the screens of the first and second displays (820a, 820b). In an embodiment, the control unit (850) can control the first driving module (830a) so that the first and second displays (820a, 820b) move together in a first direction in response to a first input signal. Additionally, the control unit (850) can control the second driving module (830b) so that the first and second displays (820a, 820b) move in a second direction different from the first direction, moving away from or closer to each other, in response to a second input signal different from the first input signal.

[0206] The angle adjustment unit (860) can be positioned between a fixed frame located on the back of a plurality of movable frames (840) and a fixed frame (801, FIG. 2) formed on the ceiling of the vehicle.

[0207] The angle adjustment unit (860) is coupled to one side of a plurality of movable frames (840) so that the plurality of movable frames (840) can operate to form a predetermined angle with respect to the fixed frame (801). Specifically, the angle adjustment unit (860) provides a driving force for the plurality of movable frames (840) to rotate so that the plurality of movable frames (840) form a horizontal or vertical angle with respect to the fixed frame (801), or form a set angle between horizontal and vertical.

[0208] The input unit (870) may be positioned on one side of the vehicle (100) so as to be spaced apart from the first and second displays (820a, 820b). The input unit (870) may be configured to include a plurality of buttons corresponding to each direction or to include an operating unit capable of tilting / moving in a plurality of directions to control the movement direction of the first and second displays (820a, 820b).

[0209] In an embodiment, when a first input signal is generated based on a first input to the input unit (870), the control unit (850) can drive the first driving module (830a) to control the first and second displays (820a, 820b) to move together in a first direction. Additionally, when a second input signal is generated based on a second input to the input unit (870), the control unit (850) can drive the second driving module (830b) to control the first and second displays (820a, 820b) to move in a second direction, either moving closer to or further apart from each other.

[0210] FIG. 4 is a conceptual diagram illustrating the movement of a vehicle rear seat display device (800) and compatibility with a front seat display device according to an embodiment of the present invention.

[0211] The vehicle rear seat display device (800) may be used by the passenger in the rear seat, or it may be operated to move toward the front seat so that the passenger in the front seat can use it.

[0212] To this end, the vehicle rear seat display device (800) can communicate with another display device located in the front seat via a router. Additionally, the vehicle rear seat display device (800) can determine whether to move the vehicle rear seat display device (800) based on the results of communication with the other display device.

[0213] Specifically, when an input is received in the input section (870) of the rear seat display device (800), for example, a hard key or a touch screen, the first processor (850a) can transmit a signal corresponding to the received input to the second processor (850b) through a router. At this time, the first processor (850a) may be, for example, an NVIDIA SYSTEM, and the second processor (850b) may be, for example, a mini PC.

[0214] As another example, the first processor (850a) can directly transmit a driving signal corresponding to the received input to the first driving module (830a) for moving the first and second displays (820a, 820b) in the forward / backward direction. Accordingly, the motor of the first driving module (830a) is driven, and a driving force is generated for moving the first and second displays (820a, 820) in the forward / backward direction.

[0215] Meanwhile, the functions of the first and second processors (850a, 850b) shown in FIG. 4 may be swapped with each other, divided to perform some operations, or performed by a single processor (850).

[0216] Additionally, an input of a request identical to the input to the input unit (870) may be made through the display of the front seat or the operating unit of the front seat of the vehicle (100). In this case, similar to the above description, a signal corresponding to the input is transmitted to the processor of the vehicle rear seat display device (800) through a router, thereby enabling the motor of the first driving module (830a) to move the first and second displays (820a, 820b) back and forth.

[0217] Additionally, the vehicle rear seat display device (800) can be used as multiple independent screens for each rear seat passenger to use, or as a full screen to display a single connected image by moving multiple screens closer together.

[0218] To this end, the vehicle rear seat display device (800) can drive the motor of the second driving module (830b) so that the first and second displays (820a, 820b) move closer to or further apart from each other, based on a signal corresponding to another input applied to the input unit (870) as shown in FIG. 4 being transmitted to the first and / or second processor (850a, 850b) (or processor (850)).

[0219] At this time, each moving frame (840, FIG. 2) on which the first and second displays (820a, 820b) are placed is equipped with a separate driving motor because it moves in a direction toward each other or in a direction toward each other. And, the motors matching each moving frame (840) rotate in opposite directions so that the plurality of moving frames (840) gradually move closer to or further away from each other.

[0220] In addition, in an embodiment, the vehicle rear seat display device (800) can adjust the angle adjustment unit (860) so that the first and second displays (820a, 820b) can form a predetermined angle with respect to a fixed frame (801, FIG. 2) placed on the ceiling of the vehicle (100). The angle adjustment unit (860) can operate to tilt the first and second displays (820a, 820b) by driving a motor so that a plurality of movable frames (840) form an angle horizontal, vertical, or in between with respect to the fixed frame (801).

[0221] For example, when the first and second displays (820a, 820b) of the vehicle rear seat display device (800) are moved to the front of the vehicle's front seat, they are transmitted to the front seat display and system through a router, and the angle adjustment unit (860) can operate so that a plurality of moving frames (840) form a predetermined angle between the horizontal and vertical with the fixed frame (801).

[0222] Additionally, for example, before the first and second displays (820a, 820b) of the vehicle rear seat display device (800) move to the front of the front seat or the front of the rear seat of the vehicle, the angle adjustment unit (860) can be operated so that a plurality of moving frames (840) form a horizontal line with the fixed frame (801).

[0223] Meanwhile, although not described in detail, when the front seat display is in operation while the vehicle is in a driving state, the processor (850) may limit the operation of the first drive module (830a) so that the first and second displays (820a, 820b) of the vehicle rear seat display device (800) do not move toward the front of the vehicle's front seat. Accordingly, driving safety is not interfered with.

[0224] Similarly, when the front seat display is operated in the vehicle's manual driving state, the processor (850) may limit the operation of the second driving module (830b) so that the first and second displays (820a, 820b) of the vehicle's rear seat display device (800) do not move in a direction that brings them closer to each other. Accordingly, the first and second displays (820a, 820b) do not obstruct the rearview mirror during manual driving by the driver.

[0225] As described above, the vehicle rear seat display device (800) according to an embodiment of the present invention provides expanded usability by driving the first and second displays (820a, 820b) to move in different directions or form a predetermined angle in conjunction with the vehicle's front seat display. In addition, by restricting the movement of the first and second displays (820a, 820b) according to the operation of the front seat display based on the vehicle's driving state, the service can be provided while considering the driving safety of the vehicle.

[0226] Hereinafter, FIGS. 5a, FIGS. 5b, FIGS. 5c, and FIGS. 5d are conceptual diagrams for explaining how a vehicle rear seat display device (800) moves in different directions and adjusts its angle.

[0227] The vehicle rear seat display device (800) can be used as an integrated full screen or as multiple independent screens by moving in directions closer to or further apart from each other at positions corresponding to the rear seats of the vehicle.

[0228] Additionally, the vehicle rear seat display device (800) moves to a position corresponding to the front seat of the vehicle or moves back to a position corresponding to the rear seat, thereby providing extended usability so that not only the rear seat occupant but also the front seat occupant can use multiple screens.

[0229] Furthermore, when the rear seat display device (800) is not using the screen, or when it is used by the occupant of the front seat of the vehicle, it operates so that a plurality of screens form a predetermined angle, thereby efficiently utilizing the vehicle space and providing comfortable audiovisual viewing to the occupant of the front seat.

[0230] FIG. 5a is an example drawing showing the initial state of a vehicle rear seat display device (800).

[0231] In the initial state of the vehicle rear seat display device (800), the first and second displays (820a, 820b) are positioned at the rear of the vehicle's front seat (or, the front of the rear seat), and one side is connected to a fixed frame (801, FIG. 2) of the ceiling to maintain a horizontal state. Accordingly, as shown in FIG. 5a (a), a plurality of movable frames (840a, 840b) face the ceiling of the vehicle, and as shown in FIG. 5a (b), the front of the first and second displays (820a, 820b) faces the floor of the vehicle.

[0232] FIG. 5b is an example drawing showing the state in which the rear seat display device (800) of a vehicle is being used by each passenger in the rear seat. That is, it is an example in which the first and second displays (820a, 820b) of the rear seat display device (800) are used as multiple independent screens in the rear seat.

[0233] The first and second displays (820a, 820b) are maintained apart by a predetermined distance (L1) and are maintained in a vertical position relative to the fixed frame (801, FIG. 5a) of the ceiling (a).

[0234] In this case, the first display (820a) is displayed for the passenger on the left side of the rear seat, and the second display (820b) is displayed for the passenger on the right side of the rear seat. Additionally, either of the first and second displays (820a, 820b) may be activated while the other remains in a deactivated state. Furthermore, the first and second displays (820a, 820b) may each be used as independent multiple screens and may simultaneously display the same content screen. Also, in the embodiment, a screen displayed on either of the first and second displays (820a, 820b) may be transmitted to the other.

[0235] Also, in FIG. 5b, a plurality of movable frames (840a, 840b) are located on the back of the first and second displays (820a, 820b) and face the front seat of the vehicle (100) (b). Additionally, an angle adjustment part (860) coupled to a part of the plurality of movable frames (840a, 840b) and a part of the fixed frame (801) supports the plurality of movable frames (840a, 840b) to maintain a horizontal state with respect to the fixed frame (801).

[0236] FIG. 5c is an example drawing showing a state in which multiple screens of a rear seat display device (800) are moved closer to each other to operate as a full screen.

[0237] Each of the multiple moving frames (840a, 840b) is equipped with a motor, and each linked motor rotates in a different direction (a) so that the first and second displays (820a, 820b) move in a direction (L2) toward each other based on a control signal from the processor (850). When one side of the first and second displays (820a, 820b) comes into contact with each other, the operation of each linked motor is stopped. The processor (850) can control the screen so that the first and second displays (820a, 820b) display a single image in full screen, or display the execution screen of the same application on multiple screens.

[0238] While a plurality of movable frames (840a, 840b) move in a direction that brings them closer to each other according to the operation of a second driving module (830b) located on the back, a fixed frame (801) on the ceiling and an angle adjustment part (860) connected thereto, and a fixed frame on the back included in the second driving module (830b) are formed to support the plurality of movable frames (840a, 840b) (b).

[0239] Meanwhile, as shown in FIG. 5c, the movement of the first and second displays (820a, 820b) so that they come closer to each other can be operated to be performed before the first and second displays (820a, 820b) move toward the front of the vehicle's front seat. In other words, while the plurality of moving frames (840) move forward and backward along the longitudinal direction of the fixed frame (801) of the ceiling, the first and second displays (820a, 820b) move together while maintaining contact with each other.

[0240] Next, FIG. 5d is an example drawing showing a state in which a plurality of screens of a rear seat display device (800) move toward the front seat so that they can be used by the occupant of the front seat.

[0241] Referring to FIG. 5d, the first and second displays (820a, 820b) move toward the front seat (110) along the longitudinal direction (L3) of the fixed frame of the vehicle ceiling in accordance with the driving of the first driving module (830a). At this time, the front of the first and second displays (820a, 820b) faces the floor and the plurality of moving frames are tilted so as to face the ceiling, moving in a folded state facing the fixed frame (801) of the ceiling (a).

[0242] When the movement is completed by reaching the end of the longitudinal direction (L3) of the fixed frame (801), the first and second displays (820a, 820b) are unfolded at an angle that can be viewed by the occupant of the front seat (110) and operate to form a predetermined angle with the fixed frame (801) of the ceiling (d).

[0243] Meanwhile, although not illustrated, a similar movement operation as above can be performed when the first and second displays (820a, 820b) move from the front seat (110) toward the rear seat. Specifically, the first and second displays (820a, 820b), which are tilted for the occupant of the front seat (110), are folded to form a horizontal position again with the fixed frame (801) of the ceiling, and then move toward the rear seat along the longitudinal direction (L3) of the fixed frame (801). When the movement is completed upon reaching the end of the longitudinal direction (L3) of the fixed frame (801), they may be unfolded to maintain the initial state described with reference to FIG. 5a or to form a vertical position with the fixed frame (801) of the ceiling so that the occupant of the rear seat can use them.

[0244] A vehicle rear seat display device (800) according to an embodiment of the present invention operates such that a plurality of driving units, namely a first driving module (830a) and a second driving module (830b), each drive so that the first and second displays (820a, 820b) move in different directions.

[0245] FIGS. 6 and FIGS. 7 are drawings for explaining the structure and operation of the first driving module (830a, FIG. 2) of the vehicle rear seat display device (800).

[0246] The first driving module (830a) includes a plurality of moving frames (840a, 840b) and a first motor (831), and can operate so that the plurality of moving frames (840) move along a guide rail (834) formed on the first fixed frame (801) based on the driving force of the first motor (831).

[0247] The first driving module (830a) is positioned to move together with the plurality of movable frames (840) along a guide rail formed on the first fixed frame (801). The first driving module (830a) drives the first and second displays (820a, 820b), which are coupled to match the front of each of the plurality of movable frames (840), to move in a first direction.

[0248] Here, the first direction may be a direction of movement between the front seat and the rear seat of the vehicle (100). Specifically, it may be a direction of movement from the rear seat of the vehicle (100) toward the front seat, or from the front seat of the vehicle (100) toward the rear seat.

[0249] Also, the first direction may be a direction in which a plurality of moving frames (840a, 840b) move along the longitudinal direction of the first fixed frame (801).

[0250] Also, the first direction may be the direction in which a plurality of moving frames (840a, 840b) move from one end (other end) of the first fixed frame (801) to the other end (one end).

[0251] The first fixed frame (801) is installed on the ceiling inside the vehicle (100) and can be formed to be long in the front-rear direction to connect the front of the front seat and the front of the rear seat of the vehicle.

[0252] Specifically, the first fixed frame (801) is installed on the ceiling of the vehicle (100) and is formed to extend the front of the front seat and the front of the rear seat. For example, the first fixed frame (801) can be positioned extending between the front seats and the rear seats. Also, the first fixed frame (801) may be made of metal. The first fixed frame (801) may have a bar structure formed extending in the longitudinal direction, for example, having a length of 740 mm in the longitudinal direction and a width of 230 mm.

[0253] A first and second display (820a, 820b) is attached to the front of each of the plurality of moving frames (840). Thus, the first and second displays (820a, 820b) can move together when the plurality of moving frames (840) move in a first direction according to the operation of the first driving module (830a).

[0254] A plurality of movable frames (840) may have a plurality of supports for supporting the first and second displays (820a, 820b) positioned on the front. That is, the first and second displays (820a, 820b) may be combined with each movable frame (840a, 840b) through a plurality of supports.

[0255] A second fixed frame (802) is disposed on the rear surface of a plurality of movable frames (840) to support the rear surface of the plurality of movable frames (840). A plurality of holes may be formed on the rear surface of the plurality of movable frames (840).

[0256] A guide rail (834) is formed on the inner side of the first fixed frame (801) to guide the movement of a plurality of movable frames (840) according to the operation of the first driving module (830a). The guide rail (834) may be formed on the inner sides of both sides along the longitudinal direction of the first fixed frame (801).

[0257] A first motor (831) of a first drive module (830a) may be mounted on the inner side of the first fixed frame (801). The first motor (831) may be arranged in a direction parallel to a plurality of movable frames (840).

[0258] When the first motor (831) is driven based on power supplied from the control unit (850, FIG. 2), a plurality of movable frames (840a, 840b) arranged side by side move along or together with the guide rail (834) formed on the inner side of the first fixed frame (801) in a first direction, for example, the longitudinal direction, or in a direction from one of the front and rear seats of the vehicle (100) toward the other. When the power supplied to the first motor (831) is interrupted, the rotation of the first motor (831) is stopped, and the movement of the plurality of movable frames (840a, 840b) ends.

[0259] The first drive module (830a) may include a first cable carrier (832) inside the first fixed frame (801). The first cable carrier (832) may be formed as a rail structure including a plurality of unit chains connected to be rotatable with each other, as shown in FIG. 6.

[0260] One side of the first cable carrier (832) can be fixed to a part of the first fixed frame (801), for example, at a point on a guide rail formed on the inner frame. Also, the other side of the first cable carrier (832) can be connected to the rear side of the first motor (831).

[0261] When a plurality of movable frames (840) move in a first direction along the guide rail according to the driving of the first motor (831), a plurality of chains included in the first cable carrier (832) gradually move together in the same direction as the plurality of movable frames (840). Accordingly, one side of the first cable carrier (832) moves along the first motor (831) of the first cable carrier (832) while being fixed at an inner point of the first fixed frame (801).

[0262] The plurality of unit chains included in the first cable bear (832) may be named as transfer rollers for transferring the plurality of movable frames (840). The first cable bear (832) may be made of a material different from the plurality of movable frames (840), for example, an elastic material.

[0263] Referring to FIG. 7, a plurality of unit chains move a plurality of movable frames (840) simultaneously in a first direction (M) according to the driving of a first motor (831) connected to the other side of the first cable carrier (832). At this time, the plurality of unit chains are fixed to a first fixed frame (801), and in this sense, the first fixed frame (801) can function as a support for the first cable carrier (832).

[0264] Additionally, the first cable bear (832) may further include a first cable bear connection module (not shown) for connecting to an inner point of the first fixed frame (801). Accordingly, one side of the first cable bear (832) can be firmly fixed to the first fixed frame (801) while a plurality of movable frames (840) move back and forth together with the guide rail (834) of the first fixed frame (801). Also, the first cable bear (832) can move back and forth in conjunction with the plurality of movable frames (840). When the plurality of movable frames (840) move back and forth, a plurality of unit chains of the first cable bear (832) are formed to gradually move along with them.

[0265] A cover (C) may be formed on the upper part of the first fixed frame (801) on which the first motor (831) is positioned. The cover (C) may be formed in a structure that is coupled to both sides of a guide rail (834) formed on the inner side of the first fixed frame (801) and moves together with the first motor (831) and the guide rail (834) according to the driving of the first driving module (830a).

[0266] The guide rail (834) formed on the first fixed frame (801) can form a rail structure customized for the first motor (831) of the first drive module (830a). Accordingly, when the first drive module (830a) is driven, the guide rail (834) can operate to move together with the first motor (831) along the rail structure formed on the inside of the first fixed frame (801). For example, the guide rail (834) can be configured to move together with other components of the first drive module (830a) along rails formed on both inner sides of the first fixed frame (801).

[0267] FIG. 7 shows a state in which a portion of the chain of the first motor (831), guide rail (834), and first cable carrier (832) is moved in a first direction (M) together with a plurality of moving frames (840a, 840b) according to the driving of the first driving module (830a).

[0268] Although not shown, as it moves in the first direction (M), a plurality of movable frames (840a, 840b) are positioned in front of the front seat. The first and second displays (820a, 820b) positioned on the front of the plurality of movable frames (840a, 840b) are positioned in front of the occupant of the front seat, so that the occupant of the front seat can use them. At this time, the second fixed frame (802) positioned on the rear of the plurality of movable frames (802) also moves in the first direction (M) along the plurality of movable frames (804). Also, although not shown, the cover (C) shown in FIG. 6 also moves together in the first direction (M) while connected to the guide rail (834). Additionally, one side of the first cable bear (832) remains fixed at a point on the inner side of the first fixed frame (801), and the other side moves together in the first direction (M) along the first motor (831).

[0269] Meanwhile, referring to FIG. 6, the rotation axis (drive axis) of the first motor (831) can be coupled with a rack and pinion gear module (833) formed on one side of the guide rail (834). Specifically, a pinion formed to protrude to engage with the drive axis of the first motor (831) can be engaged with a rack formed on one side of the guide rail (834) to form a coupling structure that drives according to the rotation of the first motor (831).

[0270] A rack formed on one side of a guide rail (834) of a first fixed frame (801) is formed along one side in the longitudinal direction of the guide rail (834) and is structured to include a plurality of gears that rotate in conjunction with a pinion coupled to the drive shaft of a first motor (831).

[0271] The drive of the rack and pinion gear module (833) is performed by receiving the driving force resulting from the rotational drive of the first motor (831). Specifically, when the first drive module (830a) is driven, the rotation axis of the first motor (831) rotates, and the pinion coupled to the rotation axis rotates. Then, as the rotating pinion engages sequentially with a plurality of teeth formed on the rack, a plurality of movable frames (840a, 840b) move in the first direction (M).

[0272] The first driving module (830a) is driven based on a driving signal transmitted from the control unit (850). The rotation axis of the first motor (831) to which power is applied rotates in a direction corresponding to the detailed direction included in the driving signal, thereby causing a plurality of moving frames (840) to move in the forward / backward direction after receiving the driving force.

[0273] For example, a plurality of moving frames (840) may move in a first direction shown in FIGS. 6 and 7, for example, from the rear seat to the front seat of the vehicle (100), according to a first rotational direction of the first motor (831). Alternatively, a plurality of moving frames (840) may move in a second rotational direction opposite to the first rotational direction, for example, from the front seat to the rear seat of the vehicle (100). Here, one of the first and second rotational directions may be clockwise and the other may be counterclockwise.

[0274] Meanwhile, in an embodiment of the present invention, the guide rail (833) is included as part of the first driving module (830a) and can be implemented to move together with a plurality of moving frames (840a, 840b) according to the driving of the first motor (831).

[0275] In other words, the first drive module (830a) includes a first motor (831), a first cable carrier (832), a rack and pinion gear module (833), and a guide rail (834), and operates to move together with a plurality of moving frames (840) along a rail formed on the first fixed frame (801) when the first drive module (830a) is driven.

[0276] In an embodiment, the control unit (850, FIG. 2) of the vehicle rear seat display device (800) controls the first driving module (830a, FIG. 2) to move along the inner rail of the first fixed frame (801) together with a plurality of moving frames (840) in a first direction toward a position corresponding to either the front seat or the rear seat of the vehicle (100). That is, the guide rail (833) moves along the rail formed on both inner sides of the first fixed frame (801) together with the first motor (831) in a first direction.

[0277] In an embodiment, the control unit (850) of the vehicle rear seat display device (800) can control the power applied to the first motor (831) to adjust the rotational speed of the first motor (831). Accordingly, the rotational speed and / or travel distance of a plurality of moving frames (840a, 840b) moving in a first direction may be different.

[0278] Meanwhile, the vehicle rear seat display device (800) according to an embodiment of the present invention can perform an angle adjustment operation to form a predetermined angle with respect to the ceiling by a plurality of movable frames (840) before and / or after driving the first driving module (830a). To this end, the vehicle rear seat display device (800) may include an angle adjustment unit (860), i.e., a third driving module (860), which is positioned adjacent to the first driving module (830a).

[0279] FIG. 8 is a drawing for explaining the angle adjustment operation after the operation of the first driving module (830a) according to an embodiment of the present invention. Here, the angle adjustment operation after the operation of the first driving module (830a) is mainly explained, and the structure and operation of the third driving module (860) will be explained in more detail below with reference to FIGS. 11 to 13.

[0280] Referring to FIG. 8, a fourth motor (861) is positioned in a direction orthogonal to the first motor (831), and the fourth motor (861) is formed to move together with the first motor (831) when the first drive module (830a) moves. The fourth motor (861) is positioned on the same line as the first motor (831) inside the first fixed frame (801) and is positioned parallel to the longitudinal direction of the first fixed frame (801).

[0281] The fourth motor (861) provides driving force for a plurality of movable frames (840a, 840b) to move to form a predetermined angle relative to the ceiling. To this end, the fourth motor (861) is coupled with a second fixed frame (802) that supports the rear of the plurality of movable frames (840a, 840b).

[0282] The fourth motor (861) can be operated to be driven after the movement of a plurality of moving frames (840a, 840b) is completed according to the driving of the first driving module (830a).

[0283] In an embodiment, while a plurality of movable frames (840a, 840b) move in a first direction according to the driving of the first driving module (830a), the plurality of movable frames (840a, 840b) may be in a folded state parallel to the ceiling of the vehicle (100).

[0284] After the plurality of movable frames (840a, 840b) move in the first direction (M, FIG. 7), the unfolding operation of the plurality of movable frames (840a, 840b) can then be performed according to the operation of the third drive module (860). Here, the unfolding operation refers to the operation in which the plurality of movable frames (840a, 840b) are tilted away from the first fixed frame (801) in a horizontal direction.

[0285] A plurality of movable frames (840a, 840b) rotate (R) away from the first fixed frame (801) according to the driving of the fourth motor (861). Accordingly, they can be unfolded so that the angle between the first fixed frame (801) and the plurality of movable frames (840a, 840b) forms, for example, 120 degrees. In this case, the angle between the back surface of the plurality of movable frames (840a, 840b) and the ceiling can form, for example, 60 degrees.

[0286] In this unfolding operation, the fourth motor (861) can be named a tilting motor in that it causes a plurality of moving frames (840a, 840b) to tilt in a specific direction in place.

[0287] When the multiple movable frames (840a, 840b) are unfolded, the second fixed frame (802) supporting the rear of the multiple movable frames (840a, 840b) is also unfolded. In this way, after the multiple movable frames (840a, 840b) move in the first direction (M, FIG. 7) according to the driving of the first driving module (830a), an additional unfolding operation is performed, thereby allowing the occupant of the front seat to view the first and second displays (820a, 820b) attached to the front of the multiple movable frames (840a, 840b) in a comfortable position.

[0288] FIGS. 9 and FIGS. 10 are drawings for explaining the structure and operation of a second driving module (830b) according to an embodiment of the present invention.

[0289] The second drive module (830b) includes a plurality of movable frames (840a, 840b), a second fixed frame (802), and second and third motors (835, 837), and operates so that the plurality of movable frames (840) move closer to each other or further apart along a guide rail (839) formed on the second fixed frame (802) according to the simultaneous driving of the second and third motors (835, 837).

[0290] The second drive module (830b) is arranged to move together with the plurality of moving frames (840) along a guide rail formed on the second fixed frame (802).

[0291] To this end, the second fixed frame (802) includes second and third motors (835, 837) that are respectively linked to a plurality of movable frames (840a, 840b). At this time, the second and third motors (835, 837) are arranged in the same direction on the same line within the second fixed frame (802). Additionally, the second and third motors (835, 837) are arranged in a direction orthogonal to the plurality of movable frames (840) within the second fixed frame (802).

[0292] A second motor (837) positioned on one side within the second fixed frame (802) is coupled to a movable frame (840a) coupled to a first display (820a) on the front. Additionally, a third motor (835) positioned on the other side within the second fixed frame (802) is coupled to a movable frame (840b) coupled to a second display (820b) on the front.

[0293] Thus, when the second drive module (830b) is driven, the driving force of the second motor (837) is transmitted to the moving frame (840a), and the driving force of the third motor (835) is transmitted to the moving frame (840b), so that a plurality of moving frames (840) move in a second direction, either moving closer to or further apart from each other.

[0294] In the second fixed frame (802), a second cable carrier (838) connected to the second motor (837) and a third cable carrier (836) connected to the third motor (835) are arranged.

[0295] Additionally, a rack and pinion gear module (839) linked to each of the second motor (837) and the third motor (835) is disposed on the second fixed frame (802). Each of the second motor (837) and the third motor (835) applies driving force to each rack and pinion gear module (839), thereby causing the linked moving frames (840a, 840b) to move simultaneously in different directions.

[0296] To this end, the second motor (837) and the third motor (835) rotate in different rotational directions. For example, according to the driving of the second driving module (830b), the second motor (837) rotates in the first rotational direction and the third motor (835) rotates in the second rotational direction simultaneously. At this time, one of the first and second rotational directions may be clockwise and the other may be counterclockwise. In this way, by the second and third motors (835, 837) rotating simultaneously in different directions according to the driving of the second driving module (830b), each of the interconnected multiple moving frames (840) is operated to move simultaneously in different directions.

[0297] At this time, the maximum distance between the multiple movable frames (840) may be, for example, 234 mm. In this state, each of the multiple movable frames (840) may move so as to be closer to each other by a maximum distance of 117 mm, so that one side of each of the multiple movable frames (840) comes into contact with each other.

[0298] The second and third motors (835, 837) apply driving force to the rack and pinion gear module (839) connected to each, so that each of the connected multiple moving frames (840a, 840b) moves in a second direction along the guide rail formed inside the second fixed frame (802).

[0299] Here, the second direction is determined by the second motor (837) and the third motor (835) rotating in different directions. That is, it refers to the direction in which a plurality of moving frames (840) move closer to or further apart from each other as the second motor (837) and the third motor (835) rotate simultaneously in different directions.

[0300] Additionally, the second direction may be a direction in which multiple moving frames (840) move simultaneously in a horizontal direction (horizontal direction) so as to move closer to or further apart from each other.

[0301] Additionally, the second direction may be a direction in which the two sides of a plurality of spaced-apart moving frames (840) move to come into contact with each other.

[0302] Additionally, the second direction may be a direction in which a plurality of movable frames (840) arranged to be in contact with each other move horizontally relative to each other with a predetermined distance. At this time, the horizontal distance of the plurality of movable frames (840) may be, for example, 170 mm.

[0303] The second drive module (830b) may be placed within a second fixed frame (802) that supports the back of a plurality of movable frames (840). The second fixed frame (802) may include second and third cable bears (836, 838) that move in conjunction with the second and third motors (835, 837), respectively.

[0304] The second drive module (830b) is coupled to one side of the first fixed frame (801), and each of the plurality of movable frames (840a, 840b) is arranged to move along the plurality of guide rails formed on the second fixed frame (802) together with the second and third motors (835, 837).

[0305] The second drive module (830b) is formed in a structure that moves together with a plurality of movable frames (840) when the first drive module (830a) is driven. Additionally, the second drive module (830b) is placed within the second fixed frame (802), and the second fixed frame (802) forms a structure coupled to support the back surface of the plurality of movable frames (840).

[0306] One side of the second fixed frame (802), for example, the top, can be coupled with a third drive module (860) disposed on the first fixed frame (801). Additionally, the front of the second fixed frame (802) can be coupled with a plurality of movable frames (840).

[0307] According to the operation of the second drive module (830b), the second motor (837) positioned on one side within the second fixed frame (802) moves along the internal guide rail between the one side and the center within the second fixed frame (802). At the same time, the third motor (835) positioned on the other side within the second fixed frame (802) moves along the internal guide rail between the other side and the center within the second fixed frame (802). Accordingly, when the plurality of movable frames (840) move in the second direction to become closer to each other, the second and third motors (835, 837) within the second fixed frame (802) also move to become closer to each other. Also, when the plurality of movable frames (840) move in the second direction to become further apart from each other, the second and third motors (835, 837) within the second fixed frame (802) also move to become further apart from each other.

[0308] A plurality of guide rails formed within the second fixed frame (802) guide the movement of the second and third motors (835, 837). Specifically, a pinion coupled to the drive shaft of each of the second and third motors (835, 837) engages with the teeth of a rack formed on the lower side of each of the plurality of guide rails, thereby helping the second and third motors (835, 837) and the plurality of moving frames (840) linked thereto to move smoothly.

[0309] Meanwhile, the second drive module (830b) includes second and third cable carriers (836, 838) disposed within the second fixed frame (802). The second cable carrier (838) is coupled with the second motor (837), and the third cable carrier (836) is coupled with the third motor (835).

[0310] One side of the second cable bear (838) is connected to the second motor (837), and the other side is fixed to the center of the second fixed frame (802). When the second motor (387) moves according to the driving of the second drive module (830b), a plurality of unit chains forming the second cable bear (838) rotate with each other and move together in the second direction along the second motor (387).

[0311] Additionally, one side of the third cable carrier (836) is connected to the third motor (835), and the other side is fixed to the center of the second fixed frame (802). When the third motor (385) moves according to the driving of the second drive module (830b), a plurality of unit chains forming the third cable carrier (836) rotate with each other and move together in the second direction along the third motor (385).

[0312] The multiple unit chains included in each of the second and third cable bears (836, 838) may be named as transfer rollers for transferring multiple movable frames (840). Additionally, the second and third cable bears (836, 838) may be made of a material different from that of the multiple movable frames (840), for example, an elastic material.

[0313] Referring to FIG. 10, a plurality of unit chains of the second and third cable bears (836, 838) move together according to the driving of the second and third motors (835, 837), and a plurality of moving frames (840a, 840b) move simultaneously in a second direction (M2) toward each other. At this time, a second and third cable bear connection module (not shown) for connecting to the central point of the second fixed frame (802) may be further included.

[0314] Meanwhile, the second and third motors (835, 837), each positioned inside the second fixed frame (802), are connected by penetrating the matching movable frames (840a, 840b). Specifically, the second motor (837) is connected to penetrate the upper rear surface of the movable frame (830a), so that when the second motor (837) moves according to the drive of the rack and pinion gear module (839), the movable frame (830a) moves together with the second motor (837) in the second direction. Additionally, the third motor (835) is connected to penetrate the upper rear surface of the movable frame (830b), so that when the third motor (835) moves according to the drive of the rack and pinion gear module (839), the movable frame (830b) moves together with the third motor (835) in the second direction.

[0315] In this way, the second and third cable bears (836, 838) are each linked with a plurality of movable frames (840a, 840b) to enable movement in the left-right direction (or horizontal direction) along the second and third motors (835 837) within the second fixed frame (802). At this time, the plurality of unit chains included in each of the second and third cable bears (836, 838) move gradually along the second and third motors (835 837).

[0316] Although not described in detail, the respective rotational axes (drive axes) of the second and third motors (835, 837) are coupled with a rack and pinion gear module (839) formed on one side inside the first fixed frame (802), for example, on the upper side inside. Specifically, a pinion protruding to engage with the respective drive axes of the second and third motors (835, 837) engages with a rack formed on one side (e.g., the upper side) of the guide rail of the second fixed frame (802), thereby forming a coupling structure that drives according to the rotation of the second and third motors (835, 837).

[0317] At this time, the second and third motors (835, 837) operate to rotate simultaneously in different directions. Accordingly, while the drive of the rack and pinion gear module linked to the second motor (837) moves the second motor (837) and the movable frame (830a) to the right, the drive of the rack and pinion gear module linked to the third motor (835) moves the third motor (835) and the movable frame (830b) to the left.

[0318] This rack and pinion gear module (839) comprises a plurality of racks formed along the longitudinal direction on one side of the second fixed frame (802), for example, on both sides of the inner upper side, and a plurality of pinions coupled to each drive shaft of the second and third motors (835, 837). That is, on the inner side of the second fixed frame (802), each of the second and third motors (835, 837) is coupled with an independent rack and pinion gear module (839).

[0319] Meanwhile, in the embodiment, the control unit (850) of the vehicle rear seat display device (800) can apply power to the second and third motors (835, 837) in response to the second signal and control each motor to rotate in a different direction. At this time, the second and third motors (835, 837) are driven simultaneously at the same rotational speed, so that the movement distance of each of the plurality of moving frames (840a, 8040b) is the same.

[0320] Additionally, the control unit (850) of the vehicle rear seat display device (800) can control the travel distance and travel speed of the second and third motors (835, 837) that are driven simultaneously. For example, the control unit (850) can control the travel speed of the multiple moving frames (840a, 840b) moving closer to or further apart from each other by controlling the power applied to the second and third motors (835, 837).

[0321] Additionally, the control unit (850) of the vehicle rear seat display device (800) can stop the rotation of the second and third motors (835, 837) based on the detection of contact on one side of a plurality of movable frames (840a, 840b) according to the driving of the second and third motors (835, 837) of the second driving module (830b). Additionally, the control unit (850) can stop the rotation of the second and third motors (835, 837) when the second and third motors (835, 837) reach both ends within the second fixed frame (802) according to the driving of the second and third motors (835, 837) of the second driving module (830b).

[0322] Meanwhile, as another embodiment, the structure of FIGS. 9 and FIGS. 10 can be modified so that the rack and pinion gear module (839) linked to the second and third motors (835, 837) is one, and the second and third motors (835, 837) share one rack and pinion gear module (839).

[0323] In this case, the control unit (850) can control only one of the second and third motors (835, 837) to drive, and accordingly, only one of the plurality of moving frames (840) can be operated to move in the horizontal direction. This allows the left passenger in the rear seat to use the first and second displays (820a, 820b) placed on the front of the plurality of moving frames (840) as a connected screen, or the right passenger in the rear seat to use the first and second displays (820a, 820b) as a connected screen.

[0324] Meanwhile, a vehicle rear seat display device (800) according to an embodiment of the present invention includes a third driving module (860) and performs a tilting operation so that a plurality of movable frames (840) form a predetermined angle based on a first fixed frame (801) installed on the ceiling of the vehicle.

[0325] FIG. 11 is a drawing for explaining the structure of a third driving module (860) for angle adjustment according to an embodiment of the present invention.

[0326] FIGS. 12 and FIGS. 13 are drawings for explaining the operation of the third drive module (860).

[0327] The third driving module (860) is formed to adjust the tilting so that a plurality of linked moving frames (840) form a predetermined angle relative to the first fixed frame (801).

[0328] To this end, the third drive module (860) is positioned across the first fixed frame (801) and the second fixed frame (802). Specifically, the fourth motor (861) of the third drive module (860) is positioned parallel to the longitudinal direction within the first fixed frame (801). Additionally, the tilting gear module (862) of the third drive module (860) is positioned to connect one side of the first fixed frame (801) and one side of the second fixed frame (802). The tilting gear module (862) receives driving force from the driving of the fourth motor (861) and operates so that a plurality of linked moving frames (840) form a set predetermined angle.

[0329] Referring together with FIG. 8, the fourth motor (860) is positioned adjacent to the first motor (831) but is positioned in a direction orthogonal to each other. One side of the fourth motor (861) is coupled to a tilting gear module (862) to provide driving force to the tilting gear module (862) when the fourth motor (861) is driven. The driving force transmitted to the tilting gear module (862) causes the second fixed frame (802) to rotate clockwise or counterclockwise relative to the first fixed frame (801). Accordingly, a plurality of movable frames (840a, 840b) coupled to the second fixed frame (802) tilt and rotate clockwise or counterclockwise along the second fixed frame (802).

[0330] In an embodiment, the control unit (850) of the vehicle rear seat display device (800) can operate the third driving module (860) before driving the first driving module (830a) according to the first signal.

[0331] Specifically, while the plurality of movable frames (840) are in a state where they are perpendicular to the first fixed frame (801), tilting rotation can be performed so that the plurality of movable frames (840) become parallel to the first fixed frame (801) according to the driving of the third driving module (860). This tilting rotation can be described as the second fixed frame (802) and the plurality of movable frames (840) folding relative to the first fixed frame (801). At this time, the fourth motor (861) of the third driving module (860) is driven in the first rotation direction.

[0332] In addition, in an embodiment, the control unit (850) of the vehicle rear seat display device (800) can operate the third driving module (860) after driving the first driving module (830a) according to the first signal.

[0333] Specifically, while the plurality of movable frames (840) are parallel to the first fixed frame (801), the plurality of movable frames (840) can perform tilting rotation to form a vertical or predetermined angle with respect to the first fixed frame (801) according to the driving of the third driving module (860). This tilting rotation can be described as the second fixed frame (802) and the plurality of movable frames (840) unfolding relative to the first fixed frame (801). At this time, the fourth motor (861) of the third driving module (860) is driven in the second rotation direction, which is opposite to the first rotation direction corresponding to the folding operation described above.

[0334] FIG. 12 is an example in which a vehicle display device (800) moves from the rear seat toward the front seat and then performs an unfolding operation.

[0335] Referring to FIG. 12, after the driving of the first driving module (830a) is completed in response to the first signal, the fourth motor (861) of the third driving module (860) is driven to perform an unfolding operation so that the second fixed frame (802) and the plurality of movable frames (840) rotate counterclockwise (R1). At this time, the angle between the second fixed frame (802) and the plurality of movable frames (840) and the first fixed frame (801) may be 120 degrees. In other words, it may be unfolded so that the angle formed between the back surface of the plurality of movable frames (840) and the first fixed frame (801) or the ceiling forms 60 degrees. In this way, the plurality of moving frames (840) are moved toward the front seat and then unfolded to form a predetermined angle according to the driving of the third driving module (860), so that the first and second displays (820a, 820) coupled to the front of the plurality of moving frames (840) can be viewed by the occupant of the front seat at a comfortable angle.

[0336] FIG. 13 is an example in which a vehicle display device (800) moves from the front seat toward the rear seat and then performs an unfolding operation.

[0337] Referring to FIG. 13, after the driving of the first driving module (830a) is completed in response to the first signal, the fourth motor (861) of the third driving module (860) is driven to perform an unfolding operation so that the second fixed frame (802) and the plurality of movable frames (840) rotate counterclockwise (R2). At this time, the angle between the second fixed frame (802) and the plurality of movable frames (840) and the first fixed frame (801) may be 90 degrees. In other words, the unfolding may be performed so that the angle formed between the back surface of the plurality of movable frames (840) and the first fixed frame (801) or the ceiling forms a right angle. In this way, the plurality of movable frames (840) are moved toward the rear seat and then unfolded to form a predetermined angle according to the driving of the third driving module (860), so that the first and second displays (820a, 820) coupled to the front of the plurality of movable frames (840) are aligned to face the occupant in the rear seat.

[0338] Meanwhile, as described with reference to FIG. 5b, the plurality of movable frames (840) may be parallel to the first fixed frame (801) in the initial state or in accordance with the folding operation before movement driven by the first driving module (820a). For example, in the initial state where the first and second displays (820a, 820b) are not used, the plurality of movable frames (840) may maintain a state parallel to the first fixed frame (801). Also, for example, when the plurality of movable frames (840) move from the rear seat to the front seat, as well as when moving back from the front seat to the rear seat, a folding operation may be performed so that the plurality of movable frames (840) are parallel to the first fixed frame (801) before driving the first driving module (830a).

[0339] The folding operation can be performed by rotating the second fixed frame (802) and the plurality of movable frames (840) clockwise according to the driving of the fourth motor (861).

[0340] According to the folding motion, the second fixed frame (802) and the plurality of movable frames (840) rotate so that they approach the first fixed frame (801), and then become parallel to the first fixed frame (801).

[0341] Meanwhile, in an initial state where a plurality of movable frames (840) are parallel to the first fixed frame (801), the control unit (850) can perform an unfolding operation by driving the third drive module (860) so that the plurality of movable frames (840) and the second fixed frame (802) form a vertical alignment with the first fixed frame (801), based on a request for use by a vehicle occupant, for example, an input to the input unit (870).

[0342] Meanwhile, in some embodiments, the folding or unfolding operation resulting from the driving of the third driving module (860) may be determined differently depending on the position and arrangement state of the plurality of moving frames (840) and the second fixed frame (801).

[0343] To this end, the vehicle rear seat display device (800) may be equipped with at least one sensor to detect the position and arrangement status of a plurality of movable frames (840). For example, the first fixed frame (801) and the plurality of movable frames (840) and / or the first fixed frame (801) and the second fixed frame (802) may include a first sensor for detecting whether the position of the plurality of movable frames (840) is a front seat or a rear seat, and a second sensor for detecting whether the plurality of movable frames (840) are in a horizontal state or formed at a predetermined angle (e.g., vertical, 60 to 120 degrees) relative to the first fixed frame (801).

[0344] In this case, the control unit (850) can determine the movement of the plurality of moving frames (840) according to at least one of the first and second driving modules, the driving status of the third driving module (860), and the degree of tilting based on the position and arrangement state of the plurality of moving frames (840) detected through the sensor.

[0345] Additionally, according to an embodiment, the control unit (850) can control the activation status of the first and second displays (820a, 820b) placed on the front of each of the plurality of moving frames (840) and the screen to be displayed differently based on the position and arrangement status of the plurality of moving frames (840) detected through a sensor.

[0346] For example, if a plurality of movable frames (840) and a second fixed frame (802) are arranged to form a horizontal position with the first fixed frame (801), the first and second displays (820a, 820b) can be controlled to a deactivated state. Also, for example, if a plurality of movable frames (840) and a second fixed frame (802) are positioned at a location corresponding to the front seat on the first fixed frame (801), the type of content screen displayed on the first and second displays (820a, 820b) can be changed. For example, the control unit (850) can control the screen to display content related to driving the vehicle when the plurality of movable frames (840) are positioned at a location corresponding to the front seat, and to display entertainment content when they are positioned at a location corresponding to the rear seat.

[0347] As described above, according to the vehicle rear seat display device of the embodiment of the present invention, the display mode of the screen changes as a plurality of screens located in the rear seat of the vehicle move closer to or further away from each other, thereby allowing them to be used as independent screens or multi-screens depending on the needs of the rear seat passengers. Accordingly, the user experience utilizing multiple screens is further expanded. In addition, by implementing the plurality of screens located in the rear seat of the vehicle so that they can move toward the front seat or back toward the rear seat, passengers in the front seat can also use the rear seat screens when necessary. Accordingly, a limited number of displays can be shared by more passengers, expanding the user experience and allowing the interior design of the vehicle to be kept simple.

[0348] The above-described invention may be implemented as computer-readable code on a medium on which a program is recorded. A computer-readable medium includes all types of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include HDD (Hard Disk Drive), SSD (Solid State Disk), SSD (Silicon Disk Drive), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc., and also include implementation in the form of a carrier wave (e.g., transmission over the Internet). Additionally, the computer may include a controller / processor of a vehicle display device (800). Accordingly, the above detailed description should not be interpreted restrictively in all respects and should be considered exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.
