[0187] In embodiments of the present invention, the 'vehicle rear seat display device' is a display device placed on the rear seat of a vehicle (100), and may be formed to be movable in different directions. The vehicle rear seat display device may be equipped with a plurality of drive 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.

[0188] 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).

[0189] As illustrated in FIG. 2, a vehicle rear seat display device (800) may be formed such that a plurality of movable frames (840a, 840b) are connected to a fixed frame (801) installed on the ceiling facing the rear seat from the front seat (110) in the vehicle (100), and first and second displays (820a, 820) are arranged on the front of the plurality of movable frames (840a, 840b), respectively.

[0190] Meanwhile, an angle adjusting unit (860) may be mounted on the back surface of the plurality of movable frames (840) to adjust the angle of the first and second displays (820a, 820b). Depending on the operation of the angle adjusting unit (860), the first and second displays (820a, 820) may be horizontal to the fixed frame (801) or may be vertical as shown.

[0191] A plurality of movable frames (840) are formed to be movable in different directions. Accordingly, the first and second displays (820a, 820b) arranged on the front of each of the plurality of movable frames (840) can move in different directions.

[0192] Specifically, the plurality of movable frames (840) can move forward of the front seats or backward of the front seats (or forward of the rear seats) along the longitudinal direction of the fixed frame (801) installed on the ceiling. Accordingly, the first and second displays (820a, 820b) move forward of the front seats of the vehicle (100) or forward of the rear seats.

[0193] Additionally, the plurality of moving frames (840) can be moved closer to or further away from each other. Accordingly, the spacing between the first and second displays (820a, 820b) is adjusted so that they come closer to (or come into contact with) or further away from each other.

[0194] When the first and second displays (820a, 820b) are positioned in front of the front seats of the vehicle (100) as the plurality of moving frames (840) move to the front of the front seats, the passengers in the front seats (driver and / or passenger in the front seat) can receive content services through the first and second displays (820a, 820b).

[0195] Meanwhile, when a plurality of moving frames (840) are positioned behind the front seats as illustrated in FIG. 2, passengers in the rear seats of the vehicle (100) can receive content services through the first and second displays (820a, 820b).

[0196] In addition, when the first and second displays (820a, 820b) are spaced apart from each other, passengers 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 in the left rear seat can receive content services through the first display (820a), and the passenger in the right rear seat can receive another content service through the second display (820b).

[0197] Meanwhile, if the spacing between the first and second displays (820a, 820b) is adjusted to become closer, the entire first and second displays (820a, 820b) can operate in full screen mode. That is, if the first and second displays (820a, 820b) become close to each other and come into contact, they can be switched to full screen mode without additional screen control.

[0198] 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 the plurality of movable frames (840) form a horizontal line with respect to the fixed frame (801) according to the operation of the angle adjustment unit (860).

[0199] The state in which the plurality of movable frames (840) illustrated in FIG. 2 form a vertical line with the fixed frame (801) is defined as an "unfolding state." In addition, although not illustrated, the state in which the plurality of movable frames (840) form a horizontal line with the fixed frame (801) is defined as a "folding state."

[0200] Referring to FIG. 2, a portion of a plurality of movable frames (840) connected to a fixed frame (801) remains fixed, and the plurality of movable frames (840) can be rotated significantly toward the fixed frame (801) as if bending until they form a horizontal line with the fixed frame (801), thereby transitioning from an “unfolding state” to an “unfolding state.”

[0201] In this way, the vehicle rear seat display device (800) according to an embodiment of the present invention is movable between the front and rear seats, and multiple displays are movable to move closer 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).

[0202] 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.

[0203] A vehicle rear seat display device (800) may include 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). In addition, the vehicle rear seat display device (800) may be connected to a system within a vehicle (100) so as to be communicable therewith through the communication unit (810).

[0204] The communication unit (810) can receive vehicle data and vehicle driving data by communicating with various devices such as a vehicle (100), a system within the vehicle (100), various sensors within the vehicle (100), and ADAS (Advanced Driver Assistance Systems) and DMS (Driver Monitoring System).

[0205] In addition, 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 linked in the vehicle (100).

[0206] The display of the rear seat vehicle display device (800) is configured to include first and second displays (820a, 820b), each having a separate frame. The first and second displays (820a, 820b) may each display different screens, the same screen, or a single connected screen.

[0207] The first and second displays (820a, 820b) may be arranged on the front surfaces of a plurality of movable frames (840) arranged side by side. In other words, the first and second displays (820a, 820b) may be arranged to be coupled to movable frames formed to be movable on the back surfaces of each of the first and second displays (820a, 820b). Accordingly, as the plurality of movable frames (840) move, the coupled first and second displays (820a, 820b) may also move together.

[0208] When the first and second displays (820a, 820b) are used as independent screens, each screen can be controlled independently. Furthermore, when the first and second displays (820a, 820b) are used as full screens, a single, integrated screen control can be performed.

[0209] In an embodiment, the screen control of the first and second displays (820a, 820b) may be performed based on the movement according to 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 seats according to the driving of the first driving module (830a), the type of displayed content may change. In addition, for example, if the first and second displays (820a, 820b) move closer or farther away from each other according to the driving of the second driving module (830b), the screen mode (e.g., full screen mode) of the displays may change.

[0210] The first and second driving modules (830a, 830b) provide driving force to move the plurality of moving frames (840) so that the first and second displays (820a, 820b) move in a first direction or a second direction. Specifically, the first driving module (830a) can transmit driving force to the plurality of moving frames (840) so that the first and second displays (820a, 820b) move in the 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 the plurality of moving frames (840) so that the first and second displays (820a, 820b) move in the second direction, that is, in a direction toward or away from each other.

[0211] First and second displays (820a, 820b) are respectively arranged on the front of the plurality of movable frames (840). One side of the plurality of movable frames (840) is connected so as to be in contact with one side of a fixed frame (801, FIG. 2) connecting 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).

[0212] A plurality of moving frames (840) may be arranged side by side with a predetermined spacing distance between them, and may be formed to be supported by an identical support frame located on the rear surface. Accordingly, when the second driving module (830b) is driven, the plurality of moving frames (840) may move closer to each other or move again to have a predetermined spacing distance while being supported by the identical support frame.

[0213] The control unit (850) controls the overall operation of the vehicle rear seat display device (800). The control unit (850) may be referred to as a processor or a PC, and may be placed, for example, within a housing located between the front seats inside the vehicle (100).

[0214] 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. In addition, 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 to move away from or toward each other in response to a second input signal different from the first input signal.

[0215] The angle adjustment unit (860) can be placed between a fixed frame located on the back of a plurality of moving frames (840) and a fixed frame (801, FIG. 2) formed on the ceiling of the vehicle.

[0216] The angle adjustment unit (860) is coupled to one side of a plurality of movable frames (840) and can operate to allow the plurality of movable frames (840) 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 plane, a vertical plane, or a set angle between the horizontal and vertical planes with respect to the fixed frame (801).

[0217] The input unit (870) may be placed 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 an operation unit that can be tilted / moved in a plurality of directions in order to control the movement direction of the first and second displays (820a, 820b).

[0218] 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 drive module (830a) to control the first and second displays (820a, 820b) to move together in a first direction. In addition, 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 drive module (830b) to control the first and second displays (820a, 820b) to move in a second direction toward or away from each other.

[0219] FIG. 4 is a conceptual diagram for explaining the movement operation of a vehicle rear seat display device (800) and compatibility with a front seat display device according to an embodiment of the present invention.

[0220] The vehicle rear seat display device (800) can be used by a rear seat passenger, or can be moved toward the front seat and operated for use by a front seat passenger.

[0221] To this end, the vehicle rear seat display device (800) can communicate with other display devices located in the front seat via a router. In addition, 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 devices.

[0222] Specifically, when an input is received through an input unit (870) of a rear-seat display device (800), such as 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) via a router. At this time, the first processor (850a) may be, for example, NVIDIA SYSTEM, and the second processor (850b) may be, for example, a mini PC.

[0223] As another example, the first processor (850a) can directly transmit a signal corresponding to the received input to the first drive module (830a) as a drive signal for moving the first and second displays (820a, 820b) in the forward / backward direction. Accordingly, the motor of the first drive module (830a) is driven, and a driving force is generated for moving the first and second displays (820a, 820) in the forward / backward direction.

[0224] Meanwhile, the functions of the first and second processors (850a, 850b) illustrated in FIG. 4 may be implemented by being swapped, performing some operations separately, or being performed by one processor (850).

[0225] In addition, an input of a request identical to the input to the input unit (870) may be made through the display or the operating unit of the front seat of the vehicle (100). In this case, similarly to the above-described case, a signal corresponding to the input is transmitted to the processor of the rear seat display device (800) of the vehicle through the router, thereby operating the motor of the first drive module (830a) so that the first and second displays (820a, 820b) move back and forth.

[0226] 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 in which multiple screens are moved closer to each other to display a single connected image.

[0227] To this end, the vehicle rear seat display device (800) can drive the motor of the second drive module (830b) to move the first and second displays (820a, 820b) closer to or further away from each other based on a signal corresponding to another input applied to the input unit (870) as illustrated in FIG. 4 being transmitted to the first and / or second processors (850a, 850b) (or processor (850)).

[0228] At this time, each of the moving frames (840, Fig. 2) on which the first and second displays (820a, 820b) are arranged moves toward or away from each other, and therefore each has a separate driving motor. In addition, the motors matching each moving frame (840) rotate in opposite directions, thereby causing the plurality of moving frames (840) to gradually approach or move away from each other.

[0229] In addition, in the 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 the fixed frame (801, FIG. 2) arranged 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 the plurality of movable frames (840) form an angle with the fixed frame (801) that is horizontal, vertical, or in a range therebetween.

[0230] 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, the information is transmitted to the front seat display and the system through the router, and the angle adjustment unit (860) can operate so that the plurality of moving frames (840) form a predetermined angle between the horizontal and vertical with the fixed frame (801).

[0231] In addition, 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) may operate so that the plurality of moving frames (840) form a horizontal line with the fixed frame (801).

[0232] Meanwhile, although not shown in detail, when the front seat display is in operation while the vehicle is in a driving state, the processor (850) can 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 prevented from being hindered.

[0233] Similarly, when the front seat display is in operation during manual driving of the vehicle, the processor (850) may limit the operation of the second driving module (830b) so that the first and second displays (820a, 820b) of the rear seat display device (800) of the vehicle do not move in a direction that brings them closer to each other. Accordingly, the first and second displays (820a, 820b) are prevented from blocking the rearview mirror during manual driving of the driver.

[0234] As described above, the vehicle rear seat display device (800) according to an embodiment of the present invention provides expanded usability by operating the first and second displays (820a, 820b) in different directions or forming a predetermined angle in conjunction with the vehicle's front seat display. In addition, by limiting the movement of the first and second displays (820a, 820b) according to the operation of the front seat display according to the vehicle's driving status, a service can be provided while taking vehicle driving safety into consideration.

[0235] Below, FIGS. 5a, 5b, 5c, and 5d are conceptual diagrams for explaining how the vehicle rear seat display device (800) moves in different directions and is angle-adjusted.

[0236] The vehicle rear seat display device (800) can be used as an integrated full screen or as multiple independent screens by moving in a direction closer or farther away from each other at a position corresponding to the rear seat of the vehicle.

[0237] In addition, the vehicle rear seat display device (800) provides expanded usability by allowing not only rear seat passengers but also front seat passengers to use multiple screens by moving to a position corresponding to the front seat of the vehicle or moving back to a position corresponding to the rear seat.

[0238] Furthermore, when the vehicle rear seat display device (800) is not used and is used by passengers in the front seats of the vehicle, it operates so that multiple screens form a set angle, thereby efficiently using the vehicle space and providing comfortable viewing and viewing to passengers in the front seats.

[0239] Figure 5a is an exemplary drawing showing the initial state of a vehicle rear seat display device (800).

[0240] 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 front seat of the vehicle (or in front of the rear seat), and one side is coupled to a fixed frame (801, FIG. 2) of the ceiling to maintain a horizontal state. Accordingly, as shown in (a) of FIG. 5A, the plurality of movable frames (840a, 840b) face the ceiling of the vehicle, and as shown in (b) of FIG. 5A, the fronts of the first and second displays (820a, 820b) face the floor of the vehicle.

[0241] FIG. 5b is an exemplary drawing showing a state in which each passenger in the rear seat is using the vehicle rear seat display device (800). That is, this is an example in which the first and second displays (820a, 820b) of the vehicle rear seat display device (800) are used as multiple independent screens in the rear seat.

[0242] The first and second displays (820a, 820b) are kept apart from each other by a predetermined distance (L1) and are kept vertical with respect to the fixed frame (801, Fig. 5a) of the ceiling (a).

[0243] 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. Furthermore, only one of the first and second displays (820a, 820b) may be activated, while the other may remain inactive. Furthermore, the first and second displays (820a, 820b) may each be used as multiple independent screens, and may simultaneously display the same content screen. Furthermore, in an embodiment, the screen displayed on one of the first and second displays (820a, 820b) may be transmitted to the other.

[0244] Also, in FIG. 5b, a plurality of movable frames (840a, 840b) are positioned on the backs of the first and second displays (820a, 820b) and face the front seats of the vehicle (100) (b). Also, an angle adjusting unit (860) coupled to a portion of the plurality of movable frames (840a, 840b) and a portion 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).

[0245] FIG. 5c is an exemplary drawing showing a state in which multiple screens of a rear seat display device (800) move closer to each other and operate in full screen.

[0246] Each of the plurality of moving frames (840a, 840b) has a motor, and the linked motors rotate in different directions (a) based on a control signal of the processor (850) so that the first and second displays (820a, 820b) move in a direction (L2) toward each other. When one side of the first and second displays (820a, 820b) contacts 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 one image in full screen or display execution screens of the same application on multiple screens.

[0247] While a plurality of moving frames (840a, 840b) move toward each other in a direction closer to each other according to the operation of the second driving module (830b) located on the rear surface, the fixed frame (801) on the ceiling, the angle adjustment unit (860) connected thereto, and the fixed frame on the rear surface included in the second driving module (830b) are formed to support the plurality of moving frames (840a, 840b) (b).

[0248] Meanwhile, the movement of the first and second displays (820a, 820b) to become closer to each other as shown in FIG. 5c may be performed before the first and second displays (820a, 820b) move toward the front of the vehicle's front seats. In other words, while the plurality of moving frames (840) move forward / 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.

[0249] Next, FIG. 5d is an exemplary drawing showing a state in which multiple screens of the rear seat display device (800) move toward the front seats and operate so that they are available to passengers in the front seats.

[0250] 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 according to 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 toward the ceiling and move in a folded state facing the fixed frame (801) of the ceiling (a).

[0251] 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 passengers in the front seats (110) and operate to form a predetermined angle with the fixed frame (801) of the ceiling (d).

[0252] Meanwhile, although not illustrated, a similar movement operation as described above may 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) tilted for the occupants of the front seat (110) are folded to form a horizontal line 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 by reaching the end of the longitudinal direction (L3) of the fixed frame (801), the initial state described with reference to FIG. 5a may be maintained, or the display may be unfolded to form a vertical line with the fixed frame (801) of the ceiling so that the occupants of the rear seat can use the display.

[0253] A vehicle rear seat display device (800) according to an embodiment of the present invention operates such that the first and second displays (820a, 820b) move in different directions according to the respective driving of a plurality of driving units, i.e., a first driving module (830a) and a second driving module (830b).

[0254] FIGS. 6 and 7 are drawings for explaining the structure and operation of the first drive module (830a, FIG. 2) of the vehicle rear seat display device (800).

[0255] The first driving module (830a) includes a plurality of moving frames (840a, 840b) and a first motor (831), and can operate to move the plurality of moving frames (840) along a guide rail (834) formed on the first fixed frame (801) based on the driving force of the first motor (831).

[0256] The first driving module (830a) is arranged to move together with the plurality of moving frames (840) along the 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 surfaces of each of the plurality of moving frames (840), to move in the first direction.

[0257] Here, the first direction may be a direction of movement between the front and rear seats 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 a direction of movement from the front seat of the vehicle (100) toward the rear seat.

[0258] Additionally, 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).

[0259] Additionally, the first direction may be a direction in which a plurality of moving frames (840a, 840b) move from one end (the other end) of the first fixed frame (801) to the other end (the first end).

[0260] The first fixed frame (801) is installed on the ceiling inside the vehicle (100) and can be formed long in the front-back direction to connect the front of the front seat and the front of the rear seat of the vehicle.

[0261] Specifically, the first fixed frame (801) is installed on the ceiling of the vehicle (100) and is formed to connect the front of the front seat and the front of the rear seat in a long manner. For example, the first fixed frame (801) may be arranged long between the front seats and the rear seats. In addition, the first fixed frame (801) may be made of a metal material. The first fixed frame (801) may have a bar structure formed long in the longitudinal direction, and may have, for example, a length of 740 mm in the longitudinal direction and a width of 230 mm.

[0262] First and second displays (820a, 820b) are respectively coupled to the front surfaces 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 the first direction according to the operation of the first driving module (830a).

[0263] A plurality of moving frames (840) may be provided with a plurality of supports for supporting the first and second displays (820a, 820b) arranged on the front. That is, the first and second displays (820a, 820b) may be coupled to each moving frame (840a, 840b) through the plurality of supports.

[0264] A second fixed frame (802) is arranged on the rear side of the plurality of moving frames (840) to support the rear side of the plurality of moving frames (840). A plurality of pores / holes may be formed on the rear side of the plurality of moving frames (840).

[0265] A guide rail (834) is formed on the inside of the first fixed frame (801) to guide the movement of a plurality of moving frames (840) according to the operation of the first driving module (830a). The guide rail (834) can be formed on the inside of each of both sides along the longitudinal direction of the first fixed frame (801).

[0266] A first motor (831) of a first driving module (830a) may be mounted on the inside of the first fixed frame (801). The first motor (831) may be arranged in a direction parallel to a plurality of moving frames (840).

[0267] When the first motor (831) is driven based on power applied 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 inside of the first fixed frame (801) in a first direction, for example, in the longitudinal direction or in a direction from one of the front and rear seats of the vehicle (100) to the other. When the power applied to the first motor (831) is stopped, the rotation of the first motor (831) is stopped, and thus the movement of the plurality of movable frames (840a, 840b) is terminated.

[0268] The first drive module (830a) may include a first cable bear (832) on the inside of the first fixed frame (801). The first cable bear (832) may be formed as a rail structure including a plurality of unit chains that are rotatably connected to each other, as illustrated in FIG. 6.

[0269] One end of the first cable bear (832) may be fixed to a portion of the first fixed frame (801), for example, to a point of a guide rail formed on the inner frame. In addition, the other end of the first cable bear (832) may be coupled to the rear of the first motor (831).

[0270] When a plurality of moving frames (840) move in the first direction along the work of the guide rail according to the driving of the first motor (831), a plurality of chains included in the first cable bear (832) gradually move together in the same direction as the plurality of moving frames (840). Accordingly, one side of the first cable bear (832) is fixed to an inner point of the first fixed frame (801) and moves along the first motor (831) of the first cable bear (832).

[0271] The plurality of unit chains included in the first cable bear (832) may be referred to as transport rollers for transporting the plurality of moving frames (840). The first cable bear (832) may be made of a different material from the plurality of moving frames (840), for example, an elastic material.

[0272] Referring to Fig. 7, a plurality of unit chains simultaneously move a plurality of moving frames (840) in a first direction (M) according to the driving of a first motor (831) connected to the other side of a first cable bear (832). At this time, the plurality of unit chains are fixed to a first fixed frame (801), and in that sense, the first fixed frame (801) can function as a support for the first cable bear (832).

[0273] In addition, the first cable bear (832) may further include a first cable bear connection module (not shown) for connection with 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 the plurality of moving frames (840) move back and forth along the guide rails (834) of the first fixed frame (801). In addition, the first cable bear (832) can move back and forth in conjunction with the plurality of moving frames (840). When the plurality of moving frames (840) move back and forth, the plurality of unit chains of the first cable bear (832) are formed to gradually move along.

[0274] A cover (C) may be formed on the upper portion of the first fixed frame (801) on which the first motor (831) is arranged. The cover (C) may be formed in a structure in which it is combined with 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).

[0275] The guide rail (834) formed on the first fixed frame (801) can form a rail structure customized to the first motor (831) of the first driving module (830a). Accordingly, when the first driving 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 inner side of the first fixed frame (801). For example, the guide rail (834) can be configured to move together with other components of the first driving module (830a) along the rails formed on both inner sides of the first fixed frame (801).

[0276] Figure 7 shows a state in which a first motor (831), a guide rail (834), and a part of a chain of a first cable bearer (832) are 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).

[0277] 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 seats. The first and second displays (820a, 820b) positioned in front of the plurality of movable frames (840a, 840b) are positioned in front of the passengers in the front seats, so that the passengers in the front seats are available for use. At this time, the second fixed frame (802) positioned at the rear of the plurality of movable frames (802) also moves in the first direction (M) along the plurality of movable frames (804). In addition, although not shown, the cover (C) illustrated in FIG. 6 also moves together in the first direction (M) in a state in which it is coupled with the guide rail (834). Additionally, one side of the first cable bear (832) remains fixed to a point on the inside of the first fixed frame (801), and the other side moves together in the first direction (M) along the first motor (831).

[0278] Meanwhile, referring to FIG. 6, the rotational axis (driving axis) of the first motor (831) can be linked with a rack and pinion gear module (833) formed on one side of the guide rail (834). Specifically, a pinion formed to protrude and engage with the driving axis of the first motor (831) can be formed as a fastening structure that engages with a rack formed on one side of the guide rail (834) to drive according to the rotation of the first motor (831).

[0279] The rack formed on one side of the guide rail (834) of the first fixed frame (801) is formed along one longitudinal side of the guide rail (834) and has a structure including a plurality of teeth that rotate in combination with a pinion coupled to the drive shaft of the first motor (831).

[0280] The rack and pinion gear module (833) is driven by receiving driving force according to the rotational drive of the first motor (831). Specifically, when the first drive module (830a) is driven, the rotational shaft of the first motor (831) rotates, and the pinion coupled to the rotational shaft rotates. Then, as the rotating pinion sequentially meshes with a plurality of gears formed on the rack, a plurality of moving frames (840a, 840b) move in the first direction (M).

[0281] 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) that has been powered rotates in a direction corresponding to the detailed direction included in the driving signal, thereby causing a plurality of moving frames (840) that have received the driving force to move forward / backward.

[0282] For example, the plurality of moving frames (840) can move in the first direction shown in FIGS. 6 and 7, for example, in the direction from the rear seat of the vehicle (100) toward the front seat, according to the first rotational direction of the first motor (831). Alternatively, the plurality of moving frames (840) can move in the second rotational direction opposite to the first rotational direction, for example, in the direction from the front seat of the vehicle (100) toward the rear seat again. Here, one of the first and second rotational directions can be clockwise and the other can be counterclockwise.

[0283] Meanwhile, in an embodiment of the present invention, the guide rail (833) may be included as a component of the first driving module (830a) and implemented to move together with a plurality of moving frames (840a, 840b) according to the driving of the first motor (831).

[0284] In other words, the first drive module (830a) includes a first motor (831), a first cable bearer (832), a rack and pinion gear module (833), and a guide rail (834), and operates to move together along a rail formed on the first fixed frame (801) together with a plurality of moving frames (840) when the first drive module (830a) is driven.

[0285] In an embodiment, the control unit (850, FIG. 2) of the vehicle rear seat display device (800) controls the first drive module (830a, FIG. 2) to move in a first direction from one of the front and rear seats of the vehicle (100) to a position corresponding to the other, along the rails on the inner side of the first fixed frame (801) together with the plurality of movable frames (840), in response to a first signal. That is, the guide rail (833) moves in the first direction together with the first motor (831) along the rails formed on both inner sides of the first fixed frame (801).

[0286] 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 rotation speed of the first motor (831). Accordingly, the rotation speed and / or movement distance of the plurality of moving frames (840a, 840b) moving in the first direction can be changed.

[0287] 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 moving frames (840) before and / or after the first driving module (830a) is driven. To this end, the vehicle rear seat display device (800) can include an angle adjustment unit (860), i.e., a third driving module (860), arranged adjacent to the first driving module (830a).

[0288] FIG. 8 is a drawing for explaining an angle adjustment operation after the operation of the first driving module (830a) according to an embodiment of the present invention. Here, the operation of the angle adjustment 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.

[0289] Referring to Fig. 8, a fourth motor (861) is arranged 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 driving 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 arranged parallel to the longitudinal direction of the first fixed frame (801).

[0290] The fourth motor (861) provides a driving force to move the plurality of moving frames (840a, 840b) to form a predetermined angle with respect to the ceiling. To this end, the fourth motor (861) is coupled to the second fixed frame (802) that supports the rear of the plurality of moving frames (840a, 840b).

[0291] The fourth motor (861) can be operated to be driven after the movement of the plurality of moving frames (840a, 840b) is completed according to the driving of the first driving module (830a).

[0292] In an embodiment, while a plurality of moving frames (840a, 840b) move in the first direction according to the driving of the first driving module (830a), the plurality of moving frames (840a, 840b) may be folded to be parallel to the ceiling of the vehicle (100).

[0293] After the plurality of moving frames (840a, 840b) move in the first direction (M, FIG. 7), an unfolding operation of the plurality of moving frames (840a, 840b) can be performed according to the operation of the third driving module (860). Here, the unfolding operation means an operation in which the plurality of moving frames (840a, 840b) are folded away from the first fixed frame (801) in the horizontal direction.

[0294] The 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, the angle between the first fixed frame (801) and the plurality of movable frames (840a, 840b) can be unfolded to form, 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.

[0295] This unfolding motion can be referred to as a tilting motor for the fourth motor (861) in that it causes the plurality of moving frames (840a, 840b) to tilt in a specific direction in place.

[0296] When the plurality of movable frames (840a, 840b) are unfolded, the second fixed frame (802) supporting the rear surfaces of the plurality of movable frames (840a, 840b) is also unfolded. In this way, after the plurality of movable frames (840a, 840b) move in the first direction (M, FIG. 7) according to the driving of the first driving module (830a), the unfolding operation is additionally performed, so that the passengers in the front seats can comfortably view the first and second displays (820a, 820b) coupled to the front surfaces of the plurality of movable frames (840a, 840b).

[0297] FIG. 9 and FIG. 10 are drawings for explaining the structure and operation of the second drive module (830b) according to an embodiment of the present invention.

[0298] The second driving module (830b) includes a plurality of moving frames (840a, 840b), a second fixed frame (802), and second and third motors (835, 837), and operates to move the plurality of moving frames (840) toward or away from each other along a guide rail (839) formed on the second fixed frame (802) according to simultaneous driving of the second and third motors (835, 837).

[0299] The second driving module (830b) is arranged to move together with the plurality of moving frames (840) along the guide rail formed on the second fixed frame (802).

[0300] To this end, the second fixed frame (802) includes second and third motors (835, 837) that are linked to a plurality of moving frames (840a, 840b), respectively. 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). In addition, the second and third motors (835, 837) are arranged in a direction orthogonal to the plurality of moving frames (840) within the second fixed frame (802).

[0301] The second motor (837) positioned on one side within the second fixed frame (802) is coupled with the movable frame (840a) coupled with the first display (820a) on the front. In addition, the third motor (835) positioned on the other side within the second fixed frame (802) is coupled with the movable frame (840b) coupled with the second display (820b) on the front.

[0302] Thus, when the second driving 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 the second direction, approaching or moving away from each other simultaneously.

[0303] A second cable bear (838) linked to a second motor (837) and a third cable bear (836) linked to a third motor (835) are arranged on the second fixed frame (802).

[0304] In addition, a rack and pinion gear module (839) linked to a second motor (837) and a third motor (835) is arranged 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.

[0305] To this end, the second motor (837) and the third motor (835) rotate in different rotation directions. For example, according to the driving of the second driving module (830b), the second motor (837) rotates in the first rotation direction and the third motor (835) simultaneously rotates in the second rotation direction. At this time, one of the first and second rotation directions may be clockwise and the other may be counterclockwise. In this way, by simultaneously rotating the second and third motors (835, 837) in different directions according to the driving of the second driving module (830b), each of the linked plurality of moving frames (840) is operated to move simultaneously in different directions.

[0306] At this time, the maximum separation distance between the plurality of moving frames (840) may be, for example, 234 mm. In this state, each of the plurality of moving frames (840) may move closer to each other by a maximum distance of 117 mm, so that one side of each of the plurality of moving frames (840) may be in contact with each other.

[0307] The second and third motors (835, 837) apply driving force to the rack and pinion gear module (839) linked to each other, thereby causing each of the plurality of linked moving frames (840a, 840b) to move in the second direction along the guide rail formed inside the second fixed frame (802).

[0308] Here, the second direction is determined by the second motor (837) and the third motor (835) rotating in different rotational directions. That is, it means a direction in which the plurality of moving frames (840) move closer to or farther away from each other as the second motor (837) and the third motor (835) rotate simultaneously in different rotational directions.

[0309] Additionally, the second direction may be a direction in which multiple moving frames (840) move simultaneously in a horizontal direction (horizontal direction) toward or away from each other.

[0310] Additionally, the second direction may be a direction in which both sides of a plurality of moving frames (840) spaced apart from each other move so that they come into contact with each other.

[0311] Additionally, the second direction may be a direction in which a plurality of moving frames (840) arranged to contact each other move horizontally with respect to each other at a predetermined distance. In this case, the horizontal movement distance of the plurality of moving frames (840) may be, for example, 170 mm.

[0312] The second drive module (830b) may be placed within a second fixed frame (802) that supports the back surface of a plurality of moving frames (840). The second fixed frame (802) may include second and third cable bearers (836, 838) that move in conjunction with the second and third motors (835, 837), respectively.

[0313] The second drive module (830b) is coupled to one side of the first fixed frame (801), and each of the plurality of moving 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).

[0314] The second driving module (830b) is formed in a structure that moves together with a plurality of moving frames (840) when the first driving module (830a) is driven. In addition, the second driving module (830b) is arranged within the second fixed frame (802), and the second fixed frame (802) forms a structure that is coupled to support the back surface of the plurality of moving frames (840).

[0315] One side, for example, the upper side, of the second fixed frame (802) can be coupled with a third driving module (860) arranged on the first fixed frame (801). In addition, the front side of the second fixed frame (802) can be coupled with a plurality of moving frames (840).

[0316] According to the operation of the second driving module (830b), the second motor (837) arranged on one side within the second fixed frame (802) moves between one side and the center within the second fixed frame (802) along the internal guide rail. At the same time, the third motor (835) arranged on the other side within the second fixed frame (802) moves between the other side and the center within the second fixed frame (802) along the internal guide rail. Accordingly, when the plurality of moving frames (840) move in the second direction to approach each other, the second and third motors (835, 837) within the second fixed frame (802) also move to approach each other. In addition, when the plurality of moving frames (840) move in the second direction to move away from each other, the second and third motors (835, 837) within the second fixed frame (802) also move to move away from each other.

[0317] 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.

[0318] Meanwhile, the second drive module (830b) includes second and third cable bearers (836, 838) arranged within the second fixed frame (802). The second cable bearer (838) is coupled with the second motor (837), and the third cable bearer (836) is coupled with the third motor (835).

[0319] One side of the second cable bear (838) is coupled 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 driving module (830b), a plurality of unit chains forming the second cable bear (838) rotate mutually and move together in the second direction along the second motor (387).

[0320] In addition, one side of the third cable bear (836) is coupled 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 driving module (830b), a plurality of unit chains forming the third cable bear (836) rotate with each other and move together in the second direction along the third motor (385).

[0321] The plurality of unit chains included in each of the second and third cable bears (836, 838) may be referred to as transport rollers for transporting the plurality of moving frames (840). In addition, the second and third cable bears (836, 838) may be made of a different material from the plurality of moving frames (840), for example, an elastic material.

[0322] 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 connection to the central point of the second fixed frame (802) may be further included.

[0323] Meanwhile, the second and third motors (835, 837) arranged inside the second fixed frame (802) are respectively coupled by penetrating the matching movable frames (840a, 840b). Specifically, the second motor (837) is coupled so as to penetrate the upper portion of the back surface of the movable frame (830a), so that when the second motor (837) moves according to the driving of the rack and pinion gear module (839), the movable frame (830a) moves together with the second motor (837) in the second direction. In addition, the third motor (835) is coupled so as to penetrate the upper portion of the back surface of the movable frame (830b), so that when the third motor (835) moves according to the driving of the rack and pinion gear module (839), the movable frame (830b) moves together with the third motor (835) in the second direction.

[0324] In this way, the second and third cable bears (836, 838) are each linked to a plurality of moving frames (840a, 840b) so as to move left and right (or horizontally) 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) gradually move along the second and third motors (835, 837).

[0325] Although not illustrated in detail, the respective rotational axes (driving axes) of the second and third motors (835, 837) are linked to a rack and pinion gear module (839) formed on one side, for example, the inner upper side, of the first fixed frame (802). Specifically, a pinion formed to protrude so as to engage with each of the driving axes of the second and third motors (835, 837) engages with a rack formed on one side (for example, the upper side) of the guide rail of the second fixed frame (802), thereby forming a fastening structure that drives according to the rotation of the second and third motors (835, 837).

[0326] At this time, the second and third motors (835, 837) operate to rotate in different directions simultaneously. Accordingly, while the operation of the rack and pinion gear module linked to the second motor (837) moves the second motor (837) and the moving frame (830a) to the right, the operation of the rack and pinion gear module linked to the third motor (835) moves the third motor (835) and the moving frame (830b) to the left.

[0327] This rack and pinion gear module (839) comprises a plurality of racks formed along the longitudinal direction on both sides of one side, for example, the inner upper side, of the second fixed frame (802), and a plurality of pinions coupled to the respective drive shafts 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).

[0328] 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 different directions. At this time, the second and third motors (835, 837) are driven simultaneously at the same rotational speed, thereby moving such that each of the plurality of moving frames (840a, 8040b) moves at the same distance.

[0329] In addition, the control unit (850) of the vehicle rear seat display device (800) can control the movement distance and movement speed of the second and third motors (835, 837) that are driven simultaneously. For example, the control unit (850) can control the movement speed at which a plurality of moving frames (840a, 840b) move closer to or farther away from each other by controlling the power applied to the second and third motors (835, 837).

[0330] In addition, 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 the plurality of moving frames (840a, 840b) according to the driving of the second and third motors (835, 837) of the second driving module (830b). In addition, 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).

[0331] Meanwhile, as another embodiment, the structure of FIGS. 9 and 10 may be modified to have a structure in which 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).

[0332] In this case, the control unit (850) can control to drive only one of the second and third motors (835, 837), and accordingly, can operate to move only one of the plurality of moving frames (840) in the horizontal direction. This allows the left passenger in the rear seat to use the first and second displays (820a, 820b) arranged in front of the plurality of moving frames (840) as connected screens, or the right passenger in the rear seat to use the first and second displays (820a, 820b) as connected screens.

[0333] 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 moving frames (840) form a predetermined angle with respect to a first fixed frame (801) installed on the vehicle ceiling.

[0334] FIG. 11 is a drawing for explaining the structure of a third drive module (860) for angle adjustment according to an embodiment of the present invention.

[0335] Figures 12 and 13 are drawings for explaining the operation of the third drive module (860).

[0336] The third drive module (860) is formed to adjust the tilting so that a plurality of linked moving frames (840) form a predetermined angle with respect to the first fixed frame (801).

[0337] To this end, the third driving module (860) is arranged across the first fixed frame (801) and the second fixed frame (802). Specifically, the fourth motor (861) of the third driving module (860) is arranged in parallel in the longitudinal direction within the first fixed frame (801). In addition, the tilting gear module (862) of the third driving module (860) is arranged to couple 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 according to the driving of the fourth motor (861) and operates so that the plurality of linked moving frames (840) form a set predetermined angle.

[0338] Referring to FIG. 8 together, the fourth motor (860) is arranged adjacent to the first motor (831), but in a direction orthogonal to each other. One side of the fourth motor (861) is coupled to the tilting gear module (862), and provides 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 with respect to the first fixed frame (801). Accordingly, a plurality of moving frames (840a, 840b) coupled to the second fixed frame (802) tilt and rotate clockwise or counterclockwise along the second fixed frame (802).

[0339] 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.

[0340] Specifically, when the plurality of moving frames (840) are in a state where they form a vertical line with the first fixed frame (801), the plurality of moving frames (840) can perform tilting rotation so that they become parallel to the first fixed frame (801) according to the driving of the third driving module (860). This tilting rotation can be said to be that the second fixed frame (802) and the plurality of moving frames (840) are folded based on the first fixed frame (801). At this time, the fourth motor (861) of the third driving module (860) is driven in the first rotational direction.

[0341] In addition, in the 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.

[0342] Specifically, when the plurality of moving frames (840) are parallel to the first fixed frame (801), the plurality of moving frames (840) can perform tilting rotation so that they form a vertical or predetermined angle with the first fixed frame (801) according to the driving of the third driving module (860). This tilting rotation can be said to be that the second fixed frame (802) and the plurality of moving frames (840) are unfolded with respect to the first fixed frame (801). At this time, the fourth motor (861) of the third driving module (860) is driven in the second rotational direction, which is the opposite direction to the first rotational direction corresponding to the folding operation described above.

[0343] Fig. 12 is an example of a vehicle display device (800) performing an unfolding operation after moving from the rear seat toward the front seat.

[0344] Referring to FIG. 12, after the first driving module (830a) is driven 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, the unfolding may be performed so that the angle 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 unfolded to form a predetermined angle according to the operation of the third driving module (860) after moving toward the front seats, so that the passengers in the front seats can comfortably view the first and second displays (820a, 820) coupled to the front of the plurality of moving frames (840).

[0345] Fig. 13 is an example of a vehicle display device (800) performing an unfolding operation after moving from the front seat to the rear seat.

[0346] Referring to Fig. 13, after the first driving module (830a) is driven 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 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 moving frames (840) are moved toward the rear seat and then unfolded to form a predetermined angle according to the operation 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) are aligned to face the passenger in the rear seat.

[0347] Meanwhile, as described with reference to FIG. 5b, the plurality of movable frames (840) may be arranged so that the plurality of movable frames (840) and the second fixed frame (802) are parallel to the first fixed frame (801) according to a folding operation before movement according to the initial state or the operation of the first driving module (820a). For example, in an initial state in which the first and second displays (820a, 820b) are not used, the plurality of movable frames (840) may maintain a state in which they are parallel to the first fixed frame (801). In addition, for example, not only when the plurality of movable frames (840) move from the rear seat to the front seat, but also when they move from the front seat to the rear seat again, a folding operation may be performed before the operation of the first driving module (830a) so that the plurality of movable frames (840) are parallel to the first fixed frame (801).

[0348] The folding motion 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).

[0349] According to the folding motion, the second fixed frame (802) and the plurality of movable frames (840) rotate to come closer to the first fixed frame (801) and then become parallel to the first fixed frame (801).

[0350] Meanwhile, in an initial state where a plurality of moving frames (840) are parallel to the first fixed frame (801), the control unit (850) can perform an unfolding operation by driving the third driving module (860) so that the plurality of moving frames (840) and the second fixed frame (802) form a vertical line with the first fixed frame (801) based on a vehicle passenger's usage request, for example, an input to the input unit (870).

[0351] Meanwhile, in some embodiments, the folding or unfolding operation according to the operation of the third driving module (860) may be determined differently depending on the positions and arrangements of the plurality of moving frames (840) and the second fixed frame (801).

[0352] To this end, the vehicle rear seat display device (800) may be equipped with at least one sensor to detect the position and arrangement of the 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 to detect whether the position of the plurality of movable frames (840) is the front seat or the rear seat, and a second sensor to detect whether the plurality of movable frames (840) are horizontal or form a predetermined angle (e.g., vertical, 60 to 120 degrees) with respect to the first fixed frame (801).

[0353] In this case, the control unit (850) can determine the movement operation of the plurality of moving frames (840) according to the configuration of at least one of the first and second driving modules and the driving and tilting degree of the third driving module (860) based on the positions and arrangement states of the plurality of moving frames (840) detected through the sensor.

[0354] In addition, according to an embodiment, the control unit (850) can differently control whether the first and second displays (820a, 820b) arranged on each front side of the plurality of moving frames (840) are activated and the screen to be displayed based on the positions and arrangement states of the plurality of moving frames (840) detected through the sensor.

[0355] For example, if a plurality of movable frames (840) and a second fixed frame (802) are arranged horizontally with the first fixed frame (801), the first and second displays (820a, 820b) can be controlled to be in an inactive state. In addition, for example, if a plurality of movable frames (840) and a second fixed frame (802) are located at positions corresponding to the front seats in 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 of the vehicle when the plurality of movable frames (840) are located at positions corresponding to the front seats, and to display entertainment content when the plurality of movable frames (840) are located at positions corresponding to the rear seats.

[0356] As described above, according to the vehicle rear seat display device according to an embodiment of the present invention, the display mode of the screens located in the rear seat of the vehicle changes as the screens move closer or farther apart, so that the screens can be used as independent screens or multi-screens according to the needs of the rear seat passengers. Accordingly, the user experience utilizing the multiple screens is further expanded. Furthermore, by implementing the multiple screens located in the rear seat of the vehicle to be able to move toward the front seats or back toward the rear seats, the rear seat screens can also be used by the front seat passengers when necessary. Accordingly, the limited number of displays can be shared by more passengers, thereby expanding the user experience and maintaining a simple vehicle interior design.

[0357] The present invention described above can be implemented as computer-readable code on a medium in which a program is recorded. The computer-readable medium includes all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, etc., and also includes media implemented in the form of carrier waves (e.g., transmission via the Internet). In addition, the computer may include a controller / processor of a vehicle display device (800). Therefore, the above detailed description should not be construed as limiting in all respects, but should be considered as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are intended to be included in the scope of the present invention.
