[0031] Although not shown in the drawings, the slidable display device 1000 can be applied to other objects with ceilings in addition to the roof panel 10 of a vehicle.

[0032] The slidable display device 1000 includes a mounting frame 1100 , a guide member 1200 , a roller unit 1300 , a panel transport unit 1400 and a display panel assembly 1500 .

[0033] The mounting frame 1100 is disposed in the space between the outer shell plate of the vehicle and the roof panel 10. The mounting frame 1100 has a guide member 1200, a roller unit 1300, and a panel transfer unit 1400 attached thereto.

[0034] 1a to 2b, the mounting frame 1100 includes a first support frame 1110, a second support frame 1120, and a fixing bracket 1130.

[0035] A plurality of first support frames 1110 (for example, a pair) are provided and spaced apart along the transverse direction above the roof panel 10. The plurality of first support frames 1110 are arranged above the roof panel 10 and are supported on the roof panel 10 by respective fixing brackets 1130.

[0036] Furthermore, a guide body 1210 of a guide member 1200 is coupled to one side end of the first support frame 1110 .

[0037] In addition, the first support frame 1110 has a rounded upper surface on one side.

[0038] The second support frame 1120 is positioned on the top of the roof panel 10 and connects a plurality of first support frames 1110. The first support frames 1110 are supported by the second support frame 1120. The second support frame 1120 is formed in a plate shape that extends in one direction and has a predetermined width in the intersecting direction.

[0039] The fixing bracket 1130 is provided on the upper part of the roof panel 10 and supports the plurality of first support frames 1110. A plurality of fixing brackets 1130 are provided and fixed to the outer surfaces of the plurality of first support frames 1110. A portion of each fixing bracket 1130 extends in the vertical direction (see FIG. 1), and the remaining portion extends in the intersecting direction.

[0040] Although not shown in the drawings, the mounting frame 1100 further includes a mounting bracket (not shown) for fixing the first support frame 1110 to an outer shell plate of the vehicle. The mounting bracket is fixed to the inner surface of the first support frame 1110. A portion of the mounting bracket extends in the vertical direction and the remaining portion extends in the cross direction.

[0041] FIG. 6a is a perspective view of a guide member according to an embodiment of the present invention, FIG. 6b is a perspective view showing a state in which a guide driving part according to an embodiment of the present invention is bent, and FIG. 6c is an enlarged perspective view showing a part where a guide main body part according to an embodiment of the present invention and an opening / closing plate are connected.

[0042] 1a to 6c, the guide member 1200 is tiltably coupled to the mounting frame 1100, supports the display panel assembly 1500, and guides the movement of the display panel assembly 1500. The guide member 1200 is configured to bend at least a portion of the display panel assembly 1500 during the tilting process.

[0043] The guide member 1200 is configured to be tiltable between an angle at which the display panel assembly 1500 is positioned horizontally and an angle at which a portion of the display panel assembly 1500 is pulled out below the mounting frame 1100 .

[0044] The guide member 1200 includes a guide main body 1210 , a guide driving portion 1220 , a guide support portion 1230 , an opening / closing plate 1240 , and a sensor 1250 .

[0045] The guide main body 1210 is provided in multiple pieces, is arranged at the end of the first support frame 1110, and is coupled to the outer surface of the first support frame 1110. The lower part of the guide main body 1210 is arranged in the slit 12 of the roof panel 10. The guide main body 1210 is provided with a guide drive unit 1220 and a sensor 1250.

[0046] The guide body 1210 also includes support protrusions 1211 and insertion protrusions 1212 to rotatably support the opening and closing plate 1240. The support protrusions 1211 and insertion protrusions 1212 of the guide body 1210 rotatably support both sides of the opening and closing plate 1240.

[0047] A portion of the support protrusion 1211 extends along the intersecting direction at the bottom of the guide main body 1210, and the remaining portion extends along one direction and protrudes forward of the first support frame 1110. The support protrusion 1211 is disposed inside the opening 11.

[0048] The insertion protrusion 1212 protrudes in the intersecting direction from the remaining portion of the support protrusion 1211. The insertion protrusion 1212 is inserted into a groove formed in the opening and closing plate 1240. The opening and closing plate 1240 is rotatably coupled to the support protrusion 1211 by the insertion protrusion 1212.

[0049] With the support protrusions 1211 positioned within the opening 11, the opening and closing plate 1240 is supported through the insertion protrusions 1212, so that when the opening and closing plate 1240 does not rotate, the opening and closing plate 1240 remains horizontally positioned with the roof panel 10, improving the aesthetics of the interior of the vehicle. In addition, since the support protrusions 1211 support the opening and closing plate 1240 at a position protruding forward from the first support frame 1110, the opening and closing plate 1240 can rotate without being interfered with by the first support frame 1110.

[0050] The guide drive portion 1220 is provided on the mounting frame 1100 and the guide main body portion 1210, and rotatably supports the guide support portion 1230.

[0051] The guide drive unit 1220 includes a motor 1221 , a link assembly 1222 , and a guide belt 1223 .

[0052] The motor 1221 is provided on the other side of the mounting frame 1100 and generates a rotational driving force. The motor 1221 is connected to the guide belt 1223 and transmits the rotational driving force to the guide belt 1223.

[0053] The motor 1221 includes a motor pulley 1221a and a motor support member 1221b.

[0054] A guide belt 1223 is wound around the motor pulley 1221a.

[0055] The motor support member 1221b is provided on the second support frame 1120 and rotatably supports the motor 1221 and the motor pulley 1221a. One side of the motor support member 1221b is recessed inward to guide a portion of the guide belt 1223 wound around the motor pulley 1221a.

[0056] The motor 1221 can be connected to a power supply generator (not shown) such as an external power supply or an internal battery, and can receive power from the power supply generator (not shown). The motor 1221 generates a rotational driving force and transmits it to the motor pulley 1221a.

[0057] The motor 1221 generates a rotational driving force when power is applied from the power generating unit. Also, when the plurality of sensors 1250 detects the rotation link 1222ba, the motor 1221 can stop generating the rotational driving force in response to a signal transmitted from the plurality of sensors 1250 to the power generating unit. This will be described in more detail with reference to the sensor 1250.

[0058] The link assembly 1222 is rotatably mounted on the guide main body 1210 and supports the guide support part 1230 and the opening / closing plate 1240. A plurality of link assemblies 1222 are provided, one for each of the plurality of guide main bodies 1210. The link assemblies 1222 are provided on both sides of the mounting frame 1100.

[0059] One of the link assemblies 1222 (the link assembly located on the left side in the drawing) receives the rotational driving force generated by the motor 1221 through the guide belt 1223, tilting (rotating) the guide support part 1230 and the opening / closing plate 1240.

[0060] The link assembly 1222 includes a link pulley 1222a, a first link 1222b, a second link 1222c, and a third link 1222d.

[0061] The link pulley 1222a is rotatably coupled to the guide main body 1210 and the first support frame 1110, and a guide belt 1223 is wound around the link pulley 1222a. The link pulley 1222a is coaxially coupled to one side of the rotation link 1222ba (and the other side of the connecting link 1222bb).

[0062] The first link 1222b tilts the guide support part 1230 using the rotational driving force transmitted from the guide belt 1223. The first link 1222b includes a rotation link 1222ba, a connecting link 1222bb, and a support link 1222bc.

[0063] The rotation link 1222ba is rotatably mounted on one side of the guide body 1210 and is coaxially coupled to the link pulley 1222a. The rotation link 1222ba is tiltable between a first position and a second position, and its rotation range is limited by a plurality of sensors 1250.

[0064] The first position is an arrangement angle at which the display panel assembly 1500 is arranged horizontally inside the roof panel 10, and the second position is an arrangement angle at which a portion of the display panel assembly 1500 is pulled out below the mounting frame 1100. Specifically, the first and second positions are positions arranged along the circumferential direction of a circle whose central axis is one side (or the intersecting direction) of the rotation link 1222ba. The second position is arranged at a position relatively higher than the first position.

[0065] The tilting angle of the rotation link 1222ba can be limited by one of a first sensor 1251 and a second sensor 1252, which will be described later.

[0066] One side of the connecting link 1222bb is connected to one side of the rotating link 1222ba and the link pulley 1222a, and the other side of the connecting link 1222bb is fixed to the support link 1222bc. The connecting link 1222bb transmits the rotational driving force of the guide belt 1223 transmitted through the rotating link 1222ba to the support link 1222bc.

[0067] The connecting link 1222bb is disposed so as to be inclined relative to the rotating link 1222ba, and the angle between the connecting link 1222bb and the rotating link 1222ba is an obtuse angle.

[0068] In addition, one side of the third link 1222d is rotatably connected to the center of the connecting link 1222bb. When the connecting link 1222bb is tilted, the third link 1222d is pressed by the connecting link 1222bb.

[0069] The support link 1222bc supports the guide support part 1230. One side of the support link 1222bc is fixed to the connecting link 1222bb, and the other side is fixed to the moving block 1231c of the guide support part 1230. The support link 1222bc tilts the guide support part 1230 when the connecting link 1222bb tilts, and as the guide support part 1230 tilts, the display panel assembly 1500 supported by the guide support part 1230 is also bent. The support link 1222bc is formed in a plate shape extending in the cross direction.

[0070] The second link 1222c is provided on the upper part of the opening and closing plate 1240 and presses the opening and closing plate 1240 in conjunction with the first link 1222b and the third link 1222d. The second link 1222c is disposed perpendicular to the opening and closing plate 1240, and one side of the second link 1222c is connected to the opening and closing plate 1240. The other side of the second link 1222c is rotatably connected to the third link 1222d.

[0071] The third link 1222d connects the first link 1222b and the second link 1222c. The first link 1222b, the second link 1222c, and the third link 1222d are connected to each other so as to be pivotally rotatable with one side of the connecting link 1222bb and the support protrusion 1211 as the rotation end, forming a four-joint link structure, which rotates relative to each other to tilt (rotate) the guide support part 1230 and the opening / closing plate 1240.

[0072] The guide belt 1223 is disposed inside the first support frame 1110 in the cross direction and transmits the rotational driving force generated by the motor 1221 to the link assembly 1222. One side of the guide belt 1223 is wound around the motor pulley 1221a, and the other side is wound around the link pulley 1222a of the link assembly 1222.

[0073] The guide support part 1230 is connected to the display panel assembly 1500 and can be tilted and disposed so as to be inclined relative to the mounting frame 1100. An end of the display panel assembly 1500 is coupled to one end of the guide support part 1230. The guide support part 1230 is pressed by the display panel assembly 1500 moving in one direction by the panel transport part 1400, and the length of the guide support part 1230 extends to guide the sliding movement of the display panel assembly 1500.

[0074] The guide support part 1230 has a telescopic structure that allows its length to be extended. The extension length of the guide support part 1230 is three to four times the vertical length of the first support frame 1110 (i.e., the height of the mounting frame 1100). Because the extension length of the guide support part 1230 is limited to three to four times the vertical length of the first support frame 1110, excessive stress generated within the guide support part 1230 due to the load of the extended guide support part 1230 is suppressed or prevented from decreasing in durability of the guide support part 1230.

[0075] FIG. 7a is a bottom perspective view showing the guide support part according to the embodiment of the present invention in an unfolded state, and FIG. 7b is an exploded perspective view of the guide support part according to the embodiment of the present invention.

[0076] 1a to 7b, the guide support part 1230 includes a main guide plate 1231, a plurality of auxiliary guide plates 1232, 1233 and a connecting guide plate 1234.

[0077] The main guide plate 1231 is connected to the support link 1222bc, and both sides of the main guide plate 1231 are supported by the support links 1222bc of the guide drive unit 1220, which are provided in plural numbers.

[0078] An inwardly recessed receiving groove 1231a is formed at one end of the main guide plate 1231. A plurality of auxiliary guide plates 1232 and 1233 are received in the receiving groove 1231a of the main guide plate 1231 so as to be expandable in a direction horizontal to the main guide plate 1231.

[0079] The main guide plate 1231 includes a moving rail 1231b, a moving block 1231c, a guide roller 1231d, a guide support roller 1231e, an auxiliary moving rail 1231f, and an auxiliary moving block 1231g.

[0080] A plurality of moving rails 1231b are provided, one at each end of the upper portion of the main guide plate 1231. The moving rails 1231b extend horizontally with the main guide plate 1231. The moving rails 1231b serve as a path for the sliding movement of the moving block 1231c.

[0081] The moving blocks 1231c are provided in a plurality and are coupled to the plurality of moving rails 1231b in a sliding manner so as to be relatively movable.

[0082] When the moving rail 1231b is fixed, the moving block 1231c can move forward or backward on the moving rail 1231b. On the other hand, when the moving block 1231c is fixed, the moving rail 1231b moves forward or backward.

[0083] Additionally, a support link 1222bc is fixed to the upper part of the moving block 1231c.

[0084] The movable block 1231c is disposed on the other side of the movable rail as shown in FIG. 4a when the guide support part 1230 is not tilted (i.e., when the guide support part 1230 is positioned horizontally), and is disposed adjacent to one side of the movable rail 1231b as shown in FIG. 4b when the guide support part 1230 is tilted (i.e., when the guide support part 1230 is positioned at an incline).

[0085] When the guide driver 1220 operates to tilt the guide supporter 1230, the movable rail 1231b, which is connected to the movable block 1231c so as to be relatively movably, is pushed aside in conjunction with the tilting (rotation) of the link assembly 1222. Since the movable rail 1231b, which is connected to the movable block 1231c so as to be relatively movably, is pushed aside in conjunction with the tilting (rotation) of the link assembly 1222, the display panel assembly 1500 can be positioned in an inclined state together with the guide supporter 1230, maintaining the same radius based on the portion where bending occurs.

[0086] The guide rollers 1231d are provided in plurality and rotatably mounted on both ends of the other side of the main guide plate 1231. The guide rollers 1231d are rotatably mounted on the first support frame 1110. The guide rollers 1231d are mounted on a portion of the first support frame 1110 that is formed with a rounded surface. When the guide support part 1230 is tilted, the guide rollers 1231d move along the rounded surface of the first support frame 1110 and support the main guide plate 1231 so that the main guide plate 1231 can be tilted stably.

[0087] The guide support rollers 1231e are provided in plurality, protrude downward from the center of the other side of the main guide plate 1231, and are in rolling contact with the upper part of the display panel assembly 1500. The plurality of guide support rollers 1231e are disposed to face second lower rollers 1322, which will be described later, when the guide support unit 1230 is tilted. When the guide support unit 1230 is tilted, the upper and lower parts of the bent portion of the display panel assembly 1500 are supported by the plurality of guide support rollers 1231e and the plurality of second lower rollers 1322, respectively, and can slide stably. Therefore, damage to the display panel assembly 1500 during sliding movement can be prevented.

[0088] A plurality of auxiliary movement rails 1231f are provided, and are provided on the inner surfaces of both sides of the main guide plate 1231 that form the accommodation groove 1231a. The auxiliary movement rails 1231f extend horizontally relative to the main guide plate 1231. The auxiliary movement rails 1231f serve as a path for the sliding movement of the auxiliary movement block 1231g.

[0089] A plurality of auxiliary moving blocks 1231g are provided, and are slidably coupled to the plurality of auxiliary moving rails 1231f, respectively. The auxiliary moving blocks 1231g are pushed or pulled along the direction parallel to the main guide plate 1231 in conjunction with the slidingly moved display panel assembly 1500, and can move on the auxiliary moving rails 1231f. An auxiliary guide plate (i.e., the first auxiliary guide plate 1232) is coupled to the auxiliary moving block 1231g, and the auxiliary moving block 1231g moves forward and backward along the auxiliary moving rails 1231f to move the auxiliary guide plate (i.e., the first auxiliary guide plate 1232) forward (i.e., unfold) or backward (i.e., retract).

[0090] The plurality of auxiliary guide plates 1232, 1233 are provided in the receiving grooves 1231a of the main guide plate 1231. The plurality of auxiliary guide plates 1232, 1233 are formed so as to be expandable in a direction horizontal to the main guide plate 1231. The plurality of auxiliary guide plates 1232, 1233 include driving rails 1232a, 1233a and driving blocks 1232b, 1233b, respectively, and are formed in a structure in which they overlap each other so as to be expandable like a telescopic structure.

[0091] In the embodiment of the present invention, as shown in Figures 7a and 7b, a case will be described in which two auxiliary guide plates 1232 and 1233 are provided. The two auxiliary guide plates 1232 and 1233 are respectively a first auxiliary guide plate 1232 and a second auxiliary guide plate 1233, the drive rails of the two auxiliary guide plates 1232 and 1233 are respectively a first drive rail 1232a and a second drive rail 1233a, and the drive blocks of the two auxiliary guide plates 1232 and 1233 are respectively a first drive block 1232b and a second drive block 1233b.

[0092] The first auxiliary guide plate 1232 is a relatively larger auxiliary guide plate among the multiple auxiliary guide plates 1232, 1233. The first auxiliary guide plate 1232 is penetrated in the direction in which the main guide plate 1231 extends. The second auxiliary guide plate 1233 is accommodated in the penetrated portion of the first auxiliary guide plate 1232.

[0093] A first driving rail 1232a and a first driving block 1232b are provided inside the first auxiliary guide plate 1232.

[0094] The first drive rail 1232a is provided on the inner surface of the first auxiliary guide plate 1232. The first drive rail 1232a extends in a direction horizontal to the first auxiliary guide plate 1232. A first drive block 1232b is slidably coupled to the first drive rail 1232a.

[0095] The first drive block 1232b is slidably coupled to the first drive rail 1232a and can move on the first drive rail 1232a by being pushed or pulled along a direction parallel to the first auxiliary guide plate 1232 in conjunction with the sliding movement of the display panel assembly 1500.

[0096] A second auxiliary guide plate 1233 is fixed to the first driving block 1232b, and the second auxiliary guide plate 1233 can be accommodated inside the first auxiliary guide plate 1232 or deployed outside the first auxiliary guide plate 1232 in conjunction with the forward and backward movement of the first driving block 1232b.

[0097] The first drive rail 1232a and the first drive block 1232b may be formed as a linear motion guide.

[0098] Furthermore, a first guide block 1232c is provided on the outer surface of the first auxiliary guide plate 1232.

[0099] The first guide block 1232c is engaged with and coupled to the movable rail 1231b at a position that does not interfere with the movable block 1231c. The first guide block 1232c has a slit recessed inward on one surface facing the movable rail 1231b. The first guide block 1232c is slidably coupled to the movable rail 1231b through the slit. The first guide block 1232c allows the first auxiliary guide plate 1232 to be stably deployed on the main guide plate 1231 or accommodated inside the main guide plate 1231.

[0100] The second auxiliary guide plate 1233 is a relatively smaller auxiliary guide plate among the multiple auxiliary guide plates 1232, 1233. The second auxiliary guide plate 1233 is formed to a size that allows it to be inserted into the perforated interior of the first auxiliary guide plate 1232. The second auxiliary guide plate 1233 is perforated in the extension direction of the first auxiliary guide plate 1232. The connecting guide plate 1234 is accommodated in the perforated portion of the second auxiliary guide plate 1233.

[0101] A second driving rail 1233a and a second driving block 1233b are provided inside the second auxiliary guide plate 1233.

[0102] The second drive rail 1233a is provided on the inner surface of the second auxiliary guide plate 1233. The second drive rail 1233a extends in a direction horizontal to the second auxiliary guide plate 1233. A second drive block 1233b is slidably coupled to the second drive rail 1233a.

[0103] The second driving block 1233b is slidably coupled to the second driving rail 1233a and can move on the second driving rail 1233a by being pushed or pulled along a direction parallel to the second auxiliary guide plate 1233 in conjunction with the sliding movement of the display panel assembly 1500.

[0104] A connecting guide plate 1234 is fixed to the second driving block 1233b, and the connecting guide plate 1234 can be accommodated inside the second auxiliary guide plate 1233 or deployed outside the second auxiliary guide plate 1233 in conjunction with the forward and backward movement of the second driving block 1233b.

[0105] The second driving rail 1233a and the second driving block 1233b may be formed as a linear motion guide.

[0106] Further, the second auxiliary guide plate 1233 is provided on its outer surface with a second guide block 1233c.

[0107] The second guide block 1233c is engaged with and coupled to the first drive rail 1232a at a position that does not interfere with the first drive block 1232b. The second guide block 1233c has a recessed slit formed in the surface facing the first drive rail 1232a. The second guide block 1233c is slidably inserted into the first drive rail 1232a through the slit. The second guide block 1233c allows the second auxiliary guide plate 1233 to stably deploy on the first auxiliary guide plate 1232 or to be accommodated inside the first auxiliary guide plate 1232.

[0108] The connecting guide plate 1234 supports an end of the display panel assembly 1500. The connecting guide plate 1234 is sized to be insertable into the hole in the second auxiliary guide plate 1233 and is slidably mounted within the hole in the second auxiliary guide plate 1233. The connecting guide plate 1234 is fixed to the second driving block 1233b and can be accommodated within the second auxiliary guide plate 1233 or deployed outside the second auxiliary guide plate 1233 in conjunction with the forward and backward movement of the second driving block 1233b.

[0109] Furthermore, the connecting guide plate 1234 has a fixing piece 1234a formed at an end thereof for fixing the display panel assembly 1500. The fixing piece 1234a is fixed to the display panel assembly 1500 by a bolt and a nut.

[0110] Furthermore, a third guide block 1234b is provided on the outer surface of the connection guide plate 1234.

[0111] The third guide block 1234b is engaged with and coupled to the second drive rail 1233a at a position that does not interfere with the second drive block 1233b. The third guide block 1234b has a recessed slit formed in the surface facing the second drive rail 1233a. The third guide block 1234b is slidably inserted into the second drive rail 1233a through the slit. The third guide block 1234b allows the connecting guide plate 1234 to stably unfold on the second auxiliary guide plate 1233 or to be accommodated inside the second auxiliary guide plate 1233.

[0112] The opening / closing plate 1240 is rotatably coupled to one side of the guide body 1210 and connected to the guide driver 1220, and rotates (tilts) together with the rotation of the guide support 1230 by the guide driver 1220.

[0113] The opening / closing plate 1240 closes the opening 11 in the roof panel 10 when the guide support portion 1230 and the display panel assembly 1500 are housed on top of the roof panel 10, and opens the opening 11 in the roof panel 10 so that the guide support portion 1230 and the display panel assembly 1500 can be deployed below the roof panel 10.

[0114] The opening and closing plate 1240 extends in the cross direction and is formed to have a size equal to or relatively smaller than the size of the opening 11 of the roof panel 10 .

[0115] A groove into which the insertion protrusion 1212 of the guide body 1210 is inserted is formed on one side of the opening / closing plate 1240. The insertion protrusion 1212 is inserted into the groove of the opening / closing plate 1240, and the opening / closing plate 1240 is rotatably supported by the guide support part 1230. The opening / closing plate 1240 is arranged horizontally with the roof panel 10 when the guide driving part 1220 is not operating. When the opening / closing plate 1240 is arranged horizontally with the roof panel 10, the opening 11 of the roof panel 10 is closed, and the roof panel 10 is generally flat, improving the aesthetics of the interior of the vehicle.

[0116] The second link 1222c of the guide actuator 1220 is fixed to the upper surface of the opening-closing plate 1240. When the guide actuator 1220 tilts the guide supporter 1230, the opening-closing plate 1240 connected via the second link 1222c also tilts. As the opening-closing plate 1240 tilts, the opening 11 of the roof panel 10 is opened, and a path is formed for the guide supporter 1230 and the display panel assembly 1500 to unfold below the roof panel 10.

[0117] The sensor 1250 is provided on the guide main body 1210 and senses the first link 1222b. The sensors 1250 sense the rotating link 1222ba moving in the circumferential direction of a circle whose central axis is one side of the rotating link 1222ba at different positions. When the sensor 1250 is positioned to face the other side of the rotating rotating link 1222ba, it transmits a signal to the power generator, which stops the rotation of the rotating link 1222ba.

[0118] The sensor 1250 includes a first sensor 1251 and a second sensor 1252 .

[0119] The first sensor 1251 is disposed on the rotation path of the rotary link 1222ba. The first sensor 1251 is disposed on the movement path on the other side of the rotary link 1222ba that revolves in the circumferential direction. When the first sensor 1251 senses the rotary link 1222ba, it transmits a sensing signal to the power generator. When the power generator receives the sensing signal from the first sensor 1251, it interrupts the power applied to the motor 1221.

[0120] The second sensor 1252 is disposed on the rotation path of the rotary link 1222ba. The second sensor 1252 is disposed at a relatively higher position than the first sensor 1251 on the movement path on the other side of the rotary link 1222ba that revolves in the circumferential direction. When the second sensor 1252 senses the rotary link 1222ba, it transmits a sensing signal to the power generation unit. When the power generation unit receives the sensing signal from the second sensor 1252, it interrupts the power applied to the motor 1221.

[0121] The driving of the motor 1221 is stopped based on the signals received by the first sensor 1251 and the second sensor 1252. Whether or not the motor 1221 is driven is determined through the first sensor 1251 and the second sensor 1252, and the degree of tilting (e.g., tilting angle) of the guide support part 1230, the opening / closing plate 1240, and the display panel assembly 1500 may be limited.

[0122] Meanwhile, within a range where the rotating link 1222ba is not detected by the first sensor 1251 and the second sensor 1252, the motor 1221 can be driven freely, and the degree of tilting (e.g., tilting angle) of the guide support part 1230, the opening / closing plate 1240, and the display panel assembly 1500 can be formed in various ways.

[0123] The roller portion 1300 supports the sliding movement of the display panel assembly 1500 .

[0124] The roller assembly 1300 includes an upper roller 1310 and a lower roller 1320 .

[0125] A plurality of upper rollers 1310 are provided and disposed in an upper region, which is a relatively high position, of the first support frame 1110. The plurality of upper rollers 1310 are spaced apart in one direction. The plurality of upper rollers 1310 rotatably support the display panel assembly 1500 from above the display panel assembly 1500.

[0126] The lower rollers 1320 are provided in plurality and are disposed in a lower region of the first support frame 1110, which is located relatively lower than the upper rollers 1310. The lower rollers 1320 rotatably support the display panel assembly 1500 below the display panel assembly 1500.

[0127] The lower rollers 1320 include a first lower roller 1321 and a second lower roller 1322 .

[0128] The first lower roller 1321 is disposed to face the plurality of upper rollers 1310. The first lower roller 1321 rotatably supports a horizontal portion of the display panel assembly 1500 that is not bent.

[0129] The second lower roller 1322 is arranged in a direction inclined downward relative to the plurality of first lower rollers 1321. The second lower roller 1322 may be arranged to be inclined at an angle of 90° to 130°, preferably 110°, relative to the plurality of first lower rollers 1321. The second lower roller 1322, together with the guide support roller 1231e, rotatably supports the bent display panel assembly 1500. The second lower roller 1322 rotatably supports the display panel assembly 1500 from below the bent display panel assembly 1500, and the guide support roller 1231e rotatably supports the display panel assembly 1500 from above the bent display panel assembly 1500.

[0130] The plurality of upper rollers 1310 and the plurality of lower rollers 1320 are each provided in the form of an idle roller.

[0131] Figure 8a is an oblique view showing the structure of a panel conveying unit according to an embodiment of the present invention, Figure 8b is an exploded oblique view showing the structure of a panel conveying unit according to an embodiment of the present invention, and Figure 9 is an exploded oblique view of a display panel assembly according to an embodiment of the present invention.

[0132] 1a to 9, the panel transport unit 1400 is attached to the mounting frame 1100 and slides the display panel assembly 1500 thereon.

[0133] The panel transfer section 1400 includes a coupling plate 1410 , a support block 1420 , a rotating shaft 1430 , a drive motor 1440 , a carrier 1450 , a pair of support bases 1460 , an LM guide 1470 , and a transfer bridge 1480 .

[0134] The coupling plate 1410 is seated on the second support frame 1120 and fixed to the plurality of first support frames 1110. A support block 1420, a driving motor support member 1441, and a pair of support stands 1460 may be fixed to the upper portion of the coupling plate 1410.

[0135] The support blocks 1420 are fixed to the upper portions of the coupling plates 1410. The support blocks 1420 are spaced apart from each other along the sliding direction of the display panel assembly 1500.

[0136] Bearings are provided inside the support block 1420. One end and the other end of the rotating shaft 1430 are rotatably attached to the bearings provided in the support block 1420. The pair of bearings fix the rotating shaft 1430 in a fixed position without eccentricity. The pair of bearings support the weight of the rotating rotating shaft 1430 and the load acting on the rotating shaft 1430.

[0137] The rotating shaft 1430 can move the carrier 1450 in the sliding movement direction of the display panel assembly 1500 through a rotational driving force transmitted by a driving motor 1440 .

[0138] The rotating shaft 1430 is formed in the form of a ball screw. The rotating shaft 1430 converts the rotation of the driving motor 1440 into a linear reciprocating motion of the carrier 1450 disposed on the rotating shaft 1430. The rotating shaft 1430 is rotated by the driving motor 1440, and can move the carrier 1450 linearly toward one side of the support block 1420 or the other side of the support block 1420.

[0139] The drive motor 1440 is coupled to the support block 1420 and transmits a driving force to the rotating shaft 1430 in the support block 1420 .

[0140] The drive motor 1440 is connected to the rotating shaft 1430 through a coupler (not shown). The coupler holds the rotating shaft 1430 even if the concentricity of the rotating shaft 1430 shifts during the movement of the carrier 1450, and allows the rotating shaft 1430 to rotate in a fixed axial direction.

[0141] The drive motor 1440 is supported by a drive motor support member 1441 that is connected to the other side of the support block 1420 and is disposed between the drive motor 1440 and the coupler. The drive motor support member 1441 is fixed to the upper part of the coupling plate 1410.

[0142] The driving motor 1440 may be connected to a power generator (not shown) such as an external power source or an internal battery to receive power from the driving motor 1440. The driving motor 1440 generates a rotational force and transmits the rotational force to the rotation shaft 1430 having a ball screw shape.

[0143] The drive motor 1440 can rotate the rotation shaft 1430 according to the position of the first LM block 1472 received from the position sensor S by a power supply generating unit (not shown). The carrier 1450 is disposed on a rotation shaft 1430 and can be moved linearly in the sliding movement direction of the display panel assembly 1500 by using a rotational driving force transmitted by a drive motor 1440 .

[0144] The pair of support bases 1460 are disposed on both sides of the support block 1420. The pair of support bases 1460 are fixed to the upper part of the coupling plate 1410 along the moving direction of the carrier 1450.

[0145] A plurality of position sensors S are provided and arranged side by side at a distance from each other along one direction on one side of the support block 1420. The position sensors S sense the position of the first LM block 1472 which moves together with the carrier 1450. The position sensors S transmit position signals of the sensed first LM block 1472 to a power supply generator (not shown).

[0146] The plurality of position sensors S are provided as limit sensors that limit the movement of the carrier 1450 by detecting the position of the first LM block 1472. The movement of the carrier 1450 is limited by the plurality of position sensors S, thereby preventing damage or breakage of the panel transfer unit 1400 and noise generation.

[0147] The power generation unit (not shown) can control (ON / OFF) the driving of the drive motor 1440 according to the position signal received from the first LM block 1472. The power generation unit (not shown) can control the drive motor 1440 to rotate the rotation shaft 1430 according to the position signal received from the first LM block 1472.

[0148] An LM guide (Linear Motion Guide) 1470 supports the sliding movement of the display panel assembly 1500 .

[0149] The LM guide 1470 includes a pair of first guide rails 1471 and a pair of first LM blocks 1472 .

[0150] The pair of first guide rails 1471 are respectively fixed to the upper portions of the pair of support bases 1460. The first guide rails 1471 serve as a path along which the first LM block 1472 moves.

[0151] The pair of first LM blocks 1472 are movably coupled to the pair of first guide rails 1471, respectively. A second transfer member 1482 is coupled to the upper part of the pair of first LM blocks 1472. The pair of first LM blocks 1472 are coupled to the second transfer member 1482 and connected to the carrier 1450 through a first transfer member 1481 formed integrally with the second transfer member 1482 (see FIGS. 8a and 8b). Therefore, the pair of first LM blocks 1472 operate in conjunction with the movement of the carrier 1450. That is, when the carrier 1450 reciprocates back and forth in one direction, the pair of first LM blocks 1472 connected to the carrier 1450 through the first transfer member 1481 and the second transfer member 1482 also reciprocates back and forth in one direction along the pair of first guide rails 1471 together with the carrier 1450.

[0152] The transfer bridge 1480 is coupled to the carrier 1450 and the top of the first LM block 1472. The transfer bridge 1480 moves the display panel assembly 1500 back and forth.

[0153] The transfer bridge 1480 includes a first transfer member 1481 and a second transfer member 1482 .

[0154] The first transfer member 1481 is coupled to the upper part of the carrier 1450. The interface board 1550 of the display panel assembly 1500 is coupled to the upper part of the first transfer member 1481. Therefore, as the carrier 1450 moves back and forth, the pair of first LM blocks 1472 as well as the interface board 1550 of the display panel assembly 1500 can slide and move.

[0155] The second transfer member 1482 is formed integrally with the first transfer member 1481 and is coupled to the upper part of the pair of first LM blocks 1472. The second transfer member 1482 is longer in the cross direction than the first transfer member 1481 and is relatively taller than the first transfer member 1481. A predetermined step is formed between the second transfer member 1482 and the first transfer member 1481. The interface board 1550 is seated on the stepped portion of the first transfer member 1481, which is formed relatively lower than the second transfer member 1482.

[0156] The connecting panel 1560 of the display panel assembly 1500 is attached to the upper part of the second transport member 1482 and can move together with the carrier 1450 in conjunction with the movement of the carrier 1450. Therefore, when the carrier 1450 reciprocates back and forth in one direction, the pair of first LM blocks 1472 also reciprocates, and the second transport member 1482 and the connecting panel 1560 coupled to the upper parts of the pair of first LM blocks 1472 both reciprocate back and forth in one direction. As the connecting panel 1560 reciprocates back and forth in one direction, the display panel 1510 of the display panel assembly 1500 also moves together.

[0157] The interface board 1550 of the display panel assembly 1500 is coupled to the first transport member 1481 and slides together with the display panel 1510 as the display panel 1510 moves and the carrier 1450 moves at the same time.

[0158] The display panel assembly 1500 is slidably mounted to the mounting frame 1100 .

[0159] 1a to 9, a display panel assembly 1500 includes a display panel 1510, a mid-cover 1520, a plurality of back bars 1530, a support panel 1540, an interface board 1550, and a connecting panel 1560.

[0160] The display panel 1510 can be slidably moved to the underside of the roof panel 10 (i.e., inside the vehicle) through the opening 11. The display panel 1510 has a connection panel 1560 attached to one side thereof, and is connected to a second transfer member 1482 by the connection panel 1560. When the carrier 1450 is moved, the display panel 1510 can be slidably moved by receiving a driving force through the first transfer member 1481 and the second transfer member 1482.

[0161] The display panel 1510 includes display elements for displaying images, drive elements for driving the display elements, wiring for transmitting various signals to the display elements and drive elements, etc. The display panel 1510 is generally arranged parallel to the connecting plate 1410 and can be bent by being driven by the guide drive unit 1220. In the bent state, the display panel 1510 can be unfolded so as to tilt toward the underside of the roof panel 10 through the opening 11 opened by the tilting operation of the opening / closing plate 1240.

[0162] The display panel 1510 may have a flexible form so that it can be bent by a guide drive unit and a guide support unit and can slide in a bent state.

[0163] The display panel 1510 is connected to the interface board 1550 via a connection panel 1560. The display panel 1510 receives electrical signals from the interface board 1550 through the connection panel 1560.

[0164] The mid cover 1520 is disposed on one surface of the display panel 1510 and supports the display panel 1510. The mid cover 1520 may have a larger area than the display panel 1510 so as to protect the display panel 1510 from external impact.

[0165] The mid cover 1520 includes a ductile material that does not deform even when the display panel assembly 1500 is repeatedly slid. More specifically, the mid cover 1520 may include a material such that the stress applied to the mid cover 1520 when the display panel 1510 is bent by the guide member 1200 and slid in the bent state is equal to or less than the yield stress of the mid cover 1520. For example, the mid cover 1520 may include metal, rubber, plastic, fabric, or the like. However, the material of the mid cover 1520 may be variously changed as long as it satisfies physical property conditions such as thermal deformation, radius of curvature, and rigidity depending on the design, and is not limited thereto.

[0166] The mid cover 1520 may have a thin thickness so that deformation does not occur even when the display panel assembly 1500 is repeatedly slid.

[0167] Between the mid cover 1520 and the display panel 1510, a first adhesive layer AD1 is disposed.

[0168] The first adhesive layer AD1 can bond the mid cover 1520 and the display panel 1510. The first adhesive layer AD1 is made of an adhesive material, and includes a thermosetting or natural curing adhesive. The first adhesive layer AD1 can include, but is not limited to, an OCA (Optical Clear Adhesive) or a PSA (Pressure Sensitive Adhesive).

[0169] A plurality of back bars 1530 are disposed on one surface of the mid cover 1520 .

[0170] The plurality of back bars 1530 support the display panel 1510 and the mid cover 1520. The thickness of the plurality of back bars 1530 may be thicker than the thickness of the mid cover 1520, and protect the display panel 1510 and the mid cover 1520 from external impact.

[0171] The plurality of back bars 1530 includes a rigid material. The plurality of back bars 1530 may include metal such as SUS (Steel Use Stainless) or Invar, or plastic. However, the material of the plurality of back bars 1530 may be variously changed depending on the design as long as it satisfies physical property conditions such as thermal deformation amount, curvature radius, rigidity, etc., and is not limited thereto.

[0172] A second adhesive layer AD2 is disposed between the plurality of back bars 1530 and the mid cover 1520.

The support panel 1540 is supported by the connecting guide plate 1234 through the fixing pieces 1234a, and the mid cover 1520 and the display panel 1510 are supported by the plurality of back bars 1530 coupled to the support panel 1540. Therefore, when the display panel 1510 is unfolded by the panel transport unit 1400, the connecting guide plate 1234 (and the plurality of auxiliary guide plates 1232 and 1233 and the main guide plate 1231) fixed to the support panel 1540 can be unfolded together by the force of the display panel 1510 sliding.

[0175] The interface board 1550 is connected to a connection panel 1560. The interface board 1550 is electrically connected to the display panel 1510 through the connection panel 1560. The interface board 1550 can exchange data, signals, or power for image display with the display panel 1510 through the connection panel 1560.

[0178] Figure 10a is a perspective view showing a state in which a display panel assembly according to an embodiment of the present invention is accommodated, Figure 10b is a bottom perspective view showing a state in which a display panel assembly according to an embodiment of the present invention is accommodated, Figure 11a is a perspective view showing a state in which a display panel assembly according to an embodiment of the present invention is bent, Figure 11b is a bottom perspective view showing a state in which a display panel of a display panel assembly according to an embodiment of the present invention is moved and exposed outside the roof panel, and Figure 12b is a bottom perspective view showing a state in which a display panel of a display panel assembly according to an embodiment of the present invention is moved and exposed outside the roof panel.

[0179] 1a to 12b, a process in which the display panel assembly 1500 passes through the opening 11 in the roof panel 10 and is deployed inside the vehicle will be described below.

[0180] 10a and 10b, the display panel assembly 1500 is housed between the roof panel 10 and the outer shell plate of the vehicle. The display panel assembly 1500 is arranged horizontally in one direction. The guide driving unit 1220 is not driven. The guide support unit 1230 is arranged in one direction. The opening 11 of the roof panel 10 is partially covered by the opening / closing plate 1240 arranged horizontally with the roof panel 10. The other side of the rotating link 1222ba of the first link 1222b is arranged to face the first sensor 1251 of the plurality of sensors 1250.

[0181] 11a and 11b, the guide actuator 1220 is actuated to bend a portion (ie, the front end) of the display panel assembly 1500. As shown in FIG.

[0182] The motor 1221 of the guide drive unit 1220 is operated to generate a rotational driving force. The rotational driving force generated by the motor 1221 is transmitted to the guide belt 1223 through the motor pulley 1221a. The rotational driving force transmitted to the guide belt 1223 is transmitted to the first link 1222b, the second link 1222c, and the third link 1222d through the link pulley 1222a.

[0183] As shown in FIG. 4b, the rotating link 1222ba of the first link 1222b rotates to a position where one side is supported by the guide body 1210 and the other side interferes with the second sensor 1252.

[0184] In conjunction with the rotation of the rotary link 1222ba, the connecting link 1222bb and the support link 1222bc also rotate by the same angle as the rotation of the rotary link 1222ba.

[0185] As the connecting link 1222bb rotates, the second link 1222c connected via the third link 1222d is pressed, tilting the open-close plate 1240 downward. With one side of the open-close plate 1240 supported by the support protrusion 1211 of the guide main body 1210, the other side is pressed by the second link 1222c, causing the open-close plate 1240 to tilt downward. When the open-close plate 1240 tilts downward, the opening 11 is opened, providing a space for the guide support part 1230 to be pulled into the opening 11.

[0186] Furthermore, as the support link 1222bc rotates together with the connecting link 1222bb, the guide support part 1230 also tilts downward. The main guide plate 1231 (and the plurality of auxiliary guide plates 1232, 1233, and connecting guide plate 1234) connected to the support link 1222bc tilts downward and is inserted into the opening 11. During the process of tilting the main guide plate 1231, the display panel assembly 1500, whose end is supported by the connecting guide plate 1234, is bent downward.

[0187] In addition, during the tilting of the guide support part 1230, the moving rail 1231b, which is relatively movably connected to the moving block 1231c of the main guide plate 1231, is pushed aside in conjunction with the tilting (rotation) of the connecting link 1222bb and the support link 1222bc so that the display panel assembly 1500 can be bent downward while maintaining the same length as before. Comparing Figures 4a and 4b, before the guide support part 1230 is tilted, the support link 1222bc is located at the other end of the main guide plate 1231, and after the guide support part 1230 is tilted, the support link 1222bc is located adjacent to one side of the main guide plate 1231.

[0188] In addition, while the guide support part 1230 is tilting, the bent end of the display panel assembly 1500 is seated on the second lower roller 1322. The upper surface of the display panel assembly 1500 seated on the second lower roller 1322 contacts the guide support roller 1231e.

[0189] In addition, during the process of tilting the guide support part 1230, the bent end of the display panel assembly 1500 is arranged parallel to the tilted opening / closing plate 1240.

[0190] 12a and 12b, the panel transfer unit 1400 is actuated, and the display panel assembly 1500 is guided by the tilted guide member 1200 and deployed below the roof panel 10 (ie, inside the vehicle).

[0191] The drive motor 1440 of the panel transfer unit 1400 is operated to generate a rotational driving force. The rotational driving force generated by the drive motor 1440 is transmitted to the carrier 1450 through the rotation shaft 1430. The carrier 1450 slides in one direction along the support block 1420 to move forward.

[0192] As the carrier 1450 moves forward, it pushes the transfer bridge 1480 in one direction. In conjunction with the forward movement of the carrier 1450, the first LM block 1472 connected via the first transfer member 1481 and the second transfer member 1482 is also guided along the first guide rail 1471 and slides.

[0193] 4c, the transfer bridge 1480 moves in one direction in conjunction with the movement of the carrier 1450, causing the connection panel 1560 (and the mid cover 1520, display panel 1510, back bar 1530, and support panel 1540) coupled to the second transfer member 1482 to slide forward. As the display panel assembly 1500 moves forward, the tilted guide support unit 1230 causes the display panel assembly 1500 to slide and bend along the tilted angle of the guide support unit 1230.

[0194] Additionally, as the display panel assembly 1500 moves forward, the guide support portion 1230 is widened by the support panel 1540 fixed to the connection guide plate 1234. As the support panel 1540 of the display panel assembly 1500 moves forward in an inclined direction, the connection guide plate 1234 also slides in an inclined direction. The connection guide plate 1234 slides in an inclined direction along the second drive rail 1233a, and the second drive block 1233b fixed to the connection guide plate 1234 is disposed at the end of the second drive rail 1233a.

[0195] When the display panel assembly 1500 moves further forward while the second driving block 1233b is positioned at the end of the second driving rail 1233a, the second driving block 1233b presses the inner surface of the second auxiliary guide plate 1233, causing the second auxiliary guide plate 1233 to expand outward from the first auxiliary guide plate 1232. In this manner, the first auxiliary guide plate 1232 expands from the inside to the outside of the main guide plate 1231.

[0196] Since the connecting guide plate 1234 and the first and second auxiliary guide plates 1232 and 1233 are only deployed horizontally relative to each other, the display panel 1510, whose ends are supported by the connecting guide plate 1234, extends horizontally in an inclined direction, resulting in the arrangement shown in Figure 4c.

[0197] Therefore, the display panel assembly 1500 is guided by the guide member 1200 so as to incline in a direction toward the lower side of the roof panel 10, and the display panel assembly 1500 can be disposed inside the vehicle.
