[0062] FIG. 1 is a conceptual diagram of a vehicle system (100) according to one embodiment of the present invention. FIG. 2 (a) is a front view of the display device (120) illustrated in FIG. 1, and FIG. 2 (b) is a diagram showing a plan view of the display device (120) illustrated in FIG. 1. FIG. 3 is a conceptual diagram showing a passenger (P) boarding the vehicle system (100) illustrated in FIG. 1 checking information output through the display device (120). FIG. 4 is a diagram showing an example of information output through the display device (120) illustrated in FIG. 3. FIG. 5 is a diagram showing a passenger checking information output through the display device (120) illustrated in FIG. 4. FIG. 6 is a diagram showing another example of information output through the display device (120) illustrated in FIG. 3.

[0063] Referring to FIGS. 1 to 6, a vehicle system (100) includes a vehicle (110) and a display device (120).

[0064] A vehicle (110) is a transport vehicle that transports people, objects, etc. to a destination. In the drawings of the present invention, the vehicle (110) is depicted as a ground-based mobility vehicle, but may also be configured as an aerial mobility vehicle, such as Urban Air Mobility (UAM). Furthermore, in addition to simply transporting passengers (P) to their destinations, the vehicle (110) may be configured to provide various services to the passengers (P) while in motion. For example, the vehicle (110) may be equipped with facilities for providing healthcare, dining, entertainment, and education services.

[0065] The display device (120) is installed on the ceiling (111) of the vehicle (110). The display device (120) may be configured to provide various visual information to the passengers (P) of the vehicle (110). Here, the visual information provided to the passengers (P) may include, for example, image information about the surroundings of the entrance (112) of the vehicle (110) when the vehicle (110) is stopped, as illustrated in FIG. 4, and a message notifying that the entrance (112) of the vehicle (110) is open. As another visual information, as illustrated in FIG. 6, when the vehicle (110) is running, information showing the current road condition centered on the vehicle (110) and a stop schedule message may be included. In addition, the vehicle system (100) may further include a side display, as illustrated in FIG. 3, which is arranged on a side surface inside the vehicle (110) and formed to provide visual information to the passengers (P).

[0066] The display device (120) includes a flat display module (121), a first curved display module (122), and a second curved display module (123). Installation of the display device (120) may be accomplished by first mounting the flat display module (121) on the ceiling (111) of the vehicle (110), and then mounting the first and second curved display modules (122, 123) on the ceiling (111) of the vehicle (110). As illustrated in FIG. 2, the peripheral area of ​​the display device (120) may be arranged to be partially covered by the headlining (111a) of the vehicle (110).

[0067] The flat display module (121) has a flat display (121a) formed to output visual information. The flat display module (121) can be placed between the first and second curved display modules (122, 123).

[0068] The first curved display module (122) has a first flat portion (122a1) and a first curved portion (122a2). The first curved display module (122) is arranged on the front side of the flat display module (121). The first curved display module (122) includes a curved display (122a) that forms a first flat portion (122a1) and a first curved portion (122a2).

[0069] The first flat surface (122a1) is formed in a continuous form from the flat surface (121a1) of the flat display module (121).

[0070] The first curved portion (122a2) is formed to extend downward from the first flat portion (122a1).

[0071] The second curved display module (123) has a second flat portion (123a1) and a second curved portion (123a2). The second curved display module (123) is arranged on the front side of the flat display module (121). The second curved display module (123) includes a curved display (123a) that forms a second flat portion (123a1) and a second curved portion (123a2).

[0072] The second flat surface (123a1) is formed in a continuous form from the flat surface (121a1) of the flat display module (121).

[0073] The second curved portion (123a2) is formed to extend downward from the second flat portion (123a1).

[0074] In this way, the first and second curved display modules (122, 123) are formed to have both a flat portion and a curved portion, unlike a general curved display that is formed to have an overall curvature. In addition, the central portion of the display device (120) is formed by combining the flat portion (121a1) of the flat display module (121) and the first and second flat portions (122a1, 123a1) of the first and second curved display modules (122, 123) to form a single flat surface. In addition, the two ends of the display device (120) are formed by bending the first and second curved portions of the first and second curved display modules (122, 123) downwardly in a curved manner, respectively.

[0075] In addition, referring to FIG. 3, the display device (120) may be configured to output one first visual information (120a) by combining an image (121a') output through one flat display (121a) and images (122a1', 122a2', 123a1', 123a2') output through two curved displays (122a, 123a). In addition, the display device (120) may be configured to output one second visual information (120b) by combining an image (121a') output through the flat display (121a) and images output through the first and second flat portions (122a1', 123a1') of the two curved displays (122a, 123a). In addition, specific visual information can be provided to passengers (P) through each image (122a2', 123a2') output through the first and second curved portions (122a2, 123a2) of the two curved displays (122a, 123a).

[0076] Here, the view of the passenger (P) can form a first view angle (V1) looking at the second visual information (120b) and a second view angle (V2) looking at the first curved portion (122a2) of the curved display (122a), for example, as shown in FIG. 3.

[0077] Meanwhile, the curvature of the first curved portion (122a2) and the curvature of the second curved portion (123a2) may be formed to be the same. That is, the first and second curved portions (122a2, 123a2) may be formed to be symmetrical in the front-rear direction with respect to the flat display module (121). Accordingly, even when multiple passengers (P) view the display device (120) from different positions, similar information can be transmitted.

[0078] Additionally, the vehicle (110) may include an entrance (112), a first seat portion (113), and a second seat portion (114).

[0079] The entrance (112) may be provided on at least one of the left and right sides of the vehicle (110).

[0080] The first sheet part (113) is provided on the front side based on the entrance (112) and can be positioned below the first curved display module (122).

[0081] The second sheet part (114) is provided on the rear side based on the entrance (112) and can be positioned below the second curved display module (123).

[0082] In addition, the visual information output from the first curved portion (122a2) and the visual information output from the second curved portion (123a2) can be made to be the same. For example, as illustrated in FIGS. 4 and 5, the first and second curved portions (122a2, 123a2) can provide the passenger (P) with visual information notifying that the vehicle's entrance (112) is open when the vehicle (110) stops. At this time, the passenger (P) looking at the first curved portion (122a2) and the passenger (P) looking at the second curved portion (123a2) can receive the same visual information.

[0083] Additionally, the visual information output from the first and second flat portions (122a1, 123a1) may be related to the visual information output from the flat portion (121a1) of the flat display module (121).

[0084] In addition, the visual information output from the first and second curved portions (122a2, 123a2) may be composed of detailed information on a portion of the visual information output from the flat portion (121a1) of the flat display module (121) and the first and second flat portions (122a1, 123a1).

[0085] According to the configuration of the vehicle system (100) described above, the various pieces of information output through the flat display module (121) and the first and second curved display modules (122, 123) can be more effectively delivered to all passengers (P) of the vehicle (110), rather than only to some of the passengers on board the vehicle (110).

[0086] Meanwhile, the conventional method of manufacturing a curved display uses a jig to create the curvature of the display, attaches a flex bar to the back of the display, and then uses the flex bar to mount the display to a counterpart. At this time, the curvature created by the jig is maintained by frictional force through screw fastening on the side of the flex bar. Furthermore, since the curvature is maintained by frictional force through screw fastening on the side of the flex bar, it is difficult to maintain the curvature inside a vehicle where continuous impact may be applied. Furthermore, since a TV box weighing approximately 3.5 kg is mounted on the back of the curved display, there is a risk of damage to the display. Furthermore, the conventional method of manufacturing a curved display using a jig can only create a constant curvature of the display, and it is difficult to apply different curvatures to only certain sections. To solve these conventional problems, the present invention proposes a novel curved display installation structure.

[0087] Hereinafter, with further reference to FIGS. 7 to 11, the installation structure of the display device (120) will be described in more detail.

[0088] Fig. 7 is a perspective view showing the display device (120) illustrated in Fig. 1 installed on the ceiling (111) of the vehicle (110). Fig. 8 is a conceptual diagram showing a state in which the connection unit (122f) of the display device (120) illustrated in Fig. 7 is in operation and the display controller (122d) is exposed. Fig. 9 is a perspective view showing the flat display module (121) illustrated in Fig. 7. Fig. 10 is a perspective view showing the first curved display module (122) illustrated in Fig. 7. Fig. 11 is a diagram showing the manufacturing process of the first curved display module (122) illustrated in Fig. 10.

[0089] Referring to FIGS. 7 to 11, the flat display module (121) and the first and second curved display modules (122, 123) may each include a display controller (121d, 122d, 123d) configured to control the flat display (121a) and the curved displays (122a, 123a). As illustrated in FIG. 9, the back surface of the flat display (121a) may be equipped with a first frame (121b) and a second frame (121c) that is disposed on the inner side of the first frame (121b) and is configured to support each other with the first frame (121b). The display controller (121d) of the flat display module (121) may be installed in the second frame (121c).

[0090] Meanwhile, the first and second curved display modules (122, 123) are respectively arranged on the front and rear sides of the flat display module (121), and most of their technical features are identical or similar except for the positions where they are arranged. Therefore, in the following more detailed description of the first and second curved display modules (122, 123), the first curved display module (122) will be used as an example for convenience of explanation.

[0091] The first curved display module (122) includes a curved display (122a), a plurality of brackets (122b), a support frame (122c), and a display controller (122d).

[0092] The curved display (122a) is formed to output various visual information and is formed to form the first flat portion (122a1) and the first curved portion (122a2).

[0093] A plurality of brackets (122b) are mounted on the back surface of the curved display (122a) to maintain the shape of the curved display (122a), and are provided with flat support portions (122b1a, 122b2a) corresponding to the first flat portion (122a1) along the extension direction and curved support portions (122b1b, 122b2b) corresponding to the first curved portion (122a2).

[0094] The support frame (122c) is combined with a plurality of brackets (122b) to support the plurality of brackets (122b).

[0095] The display controller (122d) is installed in the support frame (122c) and is formed to control the curved display (122a).

[0096] Meanwhile, the plurality of brackets (122b) may include a first bracket (122b1) and a second bracket (122b2).

[0097] The first bracket (122b1) and the second bracket (122b2) may be arranged to be spaced apart from each other in the left-right direction on the back surface of the curved display (122a) as illustrated in FIG. 10. Here, a portion of the support frame (122c) may be formed to be interposed between the first bracket (122b1) and the second bracket (122b2) to prevent distortion of the bracket (122b). That is, a portion of the support frame may be in contact with the bracket (122b) to support the bracket (122b), thereby maintaining the structure of the bracket (122b) more firmly.

[0098] Meanwhile, the support frame (122c) may include a base frame portion (122c1), a first cross frame portion (122c2), and a second cross frame portion (122c3).

[0099] The base frame portion (122c1) forms the basic skeleton of the support frame (122c).

[0100] The first cross frame part (122c2) is arranged to cross the inside of the base frame part (122c1) and is mounted on the inner surface of the first bracket (122b1) and the inner surface of the second bracket (122b2), respectively.

[0101] The second cross frame portion (122c3) connects the first cross frame portions (122c2) that are spaced apart from each other, and one of them supports the flat support portion (122b1a) of the first bracket (122b1) and the flat support portion (122b2a) of the second bracket (122b2), and the other supports the curved support portion (122b2b) of the first bracket (122b1) and the curved support portion (122b2b) of the second bracket (122b2).

[0102] Additionally, one of the second cross frame parts (122c3) may be placed on the first flat part (122a1) and the other may be placed on the first curved part (122a2).

[0103] In addition, grooves (122b1a1, 122b1b1, 122b2a1, 122b2b1) in which a base frame portion (122c1) is mounted can be formed in the flat support portions (122b1a, 122b2a) and the curved support portions (122b1b, 122b2b). Accordingly, the overall height of the display device (120) can be minimized along with the height of the support frame (122c), and the internal space of the vehicle (110) can be further secured.

[0104] The overall structure of the support frame (122c) can be maintained more stably without distortion.

[0105] As shown in Fig. 10, the curved support portion (122b1b, 122b2b) may be provided with a reinforcing frame (122b3) that is spaced apart from another of the second cross frame portions to reinforce the prevention of twisting of the curved support portion (122b1b, 122b2b).

[0106] In addition, the display controller (122d) can be mounted on the second cross frame portion (122c3). The second cross frame portion (122c3) is positioned between the first cross frame portion (122c2) to form a structure that is mutually supported by the first and second brackets (122b1, 122b2). Accordingly, the fixed state of the display controller (122d) mounted on the second cross frame portion (122c3) can be stably maintained.

[0107] Meanwhile, referring to FIG. 11, a method for manufacturing the display device (120) installed on the ceiling (111) of a vehicle (110) first forms a part of a flat surface of a curved display (122a) into a curved surface using a jig.

[0108] Next, in order to maintain the shape of the curved display (122a), a plurality of brackets (122b) are mounted on the back surface of the curved display (122a).

[0109] And, it includes a step of mounting a support frame (122c) on a plurality of brackets (122b). Thereafter, a display controller (122d) is mounted on the support frame (122c). The display controller (122d) can be mounted on the second cross frame portion (122c3) of the support frame (122c).

[0110] Here, each of the plurality of brackets (122b) has, along the extension direction, a flat support portion (122b1a, 122b2a) corresponding to a flat portion where a curved surface is not formed in the curved display (122a), and a curved support portion (122b1b, 122b2b) corresponding to a curved portion of the curved display (122a).

[0111] According to the structure of the first curved display module (122) as described above, the curved display (122a) can be fixed with a plurality of brackets (122b) formed to match the desired curvature, thereby stably maintaining an accurate curvature. In addition, the structural stability of the first curved display module (122) can be secured by the structure of the support frame (122c), and the assembling ability with the counterpart can be improved. In addition, by mounting the display controller (122d) on the support frame (122c), the display device (120) is not damaged even in an environment where continuous shock and vibration occur, such as a vehicle (110), so that the durability of the display device (120) can be greatly improved.

[0112] Meanwhile, the display device (120) frequently encounters situations where its back surface must be checked during installation and maintenance. In addition, the display device (120) of the present invention has a structural feature of being installed on the ceiling (111) of a vehicle (110), and an entrance door, etc. are provided at the entrance (112) of the vehicle (110), so that the space for mounting the display device (120) on the ceiling (111) of the vehicle (110) is narrow. Under these installation conditions of the display device (120), when a general hinge (pivot joint) structure is applied to the display device (120) as in the conventional general method, interference occurs with the vehicle body (111b) during hinge operation due to the thickness of the display device (120). In order to solve this problem, the display device (120) of the present invention is provided with a connection unit (122f).

[0113] Referring further to FIGS. 12 to 15 below, the mechanism of the display device (120) having the connection unit (122f) will be described in more detail.

[0114] Fig. 12 is a drawing showing the installation process of the display device (120) shown in Fig. 7. Fig. 13 is a drawing showing the display device (120) shown in Fig. 8 when viewed from the side with the connection unit (122f) as the center. Fig. 14 is a drawing conceptually showing the motion trajectory of the connection unit (122f) while the first link (122f1) shown in Fig. 13 rotates 90 degrees. Fig. 15 is a drawing conceptually showing the process of the display device (120) moving relatively from a first state to a second state as the connection unit (122f) of the display device (120) shown in Fig. 8 operates.

[0115] Referring to FIGS. 12 to 15, a display device (120) of a vehicle system (100) includes a display (121a, 122a, 123a) for outputting visual information, a plurality of brackets (122b) mounted on the back of the displays (121a, 122a, 123a), a support frame (122c) coupled to the plurality of brackets (122b), a display controller (122d) installed on the support frame (122c) and formed to control the displays (121a, 122a, 123a), a fixed frame (122e), and a connection unit (122f). Here, the display (121a, 122a, 123a) may be formed as a flat display (121a), a curved display (122a, 123a). In addition, in a more detailed description of the mechanism of the display device (120) having the connection unit (122f), the first curved display module (122) will be described as an example for convenience of explanation.

[0116] In addition, the flat display (121a) and the curved display (122a, 123a) may be provided in the flat display module (121) and the first and second curved display modules (122, 123), respectively. In addition, as illustrated in FIG. 12, the display device (120) may first install the flat display module (121) on the body (111b) of the vehicle (110), and then install the first and second curved display modules (122, 123) on both sides of the flat display module (121) with the flat display module (121) as the center.

[0117] The fixed frame (122e) is installed on the body (111b) of the ceiling (111) of the vehicle (110).

[0118] The connecting unit (122f) is configured to connect the support frame (122c) to the fixed frame (122e) so that it can move relative to the fixed frame.

[0119] In addition, the display (121a, 122a, 123a), for example, the curved display (122a) of the first curved display module (122), may be relatively movable between a first state in which it is arranged to form a part of the ceiling (111) of the vehicle (110), and a second state in which it is arranged to be inclined downwards and expose the display controller (122d). The display controller (122d) of the second state curved display (122a) may be arranged to be inclined toward an entrance (112) provided on the side of the vehicle (110).

[0120] Meanwhile, the fixed frame (122e) may be provided with a locking part (122e1).

[0121] The locking portion (122e1) may be formed to limit relative movement of the display (121a, 122a, 123a), for example, the curved display (122a) of the first curved display module (122), by locking the support frame (122c) in the first state in which the display is arranged to form a part of the ceiling (111) of the vehicle (110). Accordingly, the second state of the curved display (122a) can be maintained more stably.

[0122] Meanwhile, the connection unit (122f) may include a first link (122f1) and a second link (122f2).

[0123] The first link (122f1) is hinge-connected to the fixed frame (122e) and the support frame (122c), respectively.

[0124] The second link (122f2) has a hinge axis (122f2a1, 122f2b1) parallel to the hinge axis (122f1a1, 122f1b1) of the first link (122f1), but is hinge-connected to the fixed frame (122e) and the support frame (122c) while being spaced apart from the first link (122f1), and may be formed longer than the first link (122f1).

[0125] Additionally, the first link (122f1) may have a first hinge point (122f1a) and a second hinge point (122f1b), and the second link (122f2) may have a third hinge point (122f2a) and a fourth hinge point (122f2b).

[0126] The first hinge point (122f1a) may be connected to one end of the fixed frame, and the second hinge point (122f1b) may be connected to one end of the support frame.

[0127] The third hinge point (122f2a) may be positioned at a position spaced apart from the first hinge point toward the other end of the fixed frame (122e). In addition, the fourth hinge point (122f2b) may be formed at a position spaced apart from the second hinge point (122f1b) toward the other end of the support frame (122c).

[0128] Additionally, the gap between the first hinge point (122f1a) and the third hinge point (122f2a) may be formed wider than the gap between the second hinge point (122f1b) and the fourth hinge point (122f2b).

[0129] Additionally, in the first state where it is arranged to form a part of the ceiling (111) of the vehicle (110), the second hinge point (122f1b) and the fourth hinge point (122f2b) may be positioned lower than the first hinge point (122f1a) and the third hinge point (122f2a).

[0130] That is, in the first state, the support frame (122c) located on the connecting line of the first and third hinge points (122f1a, 122f2a) is positioned lower than the fixed frame (122e) located on the connecting line of the second and fourth hinge points (122f1b, 122f2b). Accordingly, the rotation mechanism of the display device (120) can be implemented more stably.

[0131] In contrast, in the first state, if the support frame (122c) on the connecting line of the first and third hinge points (122f1a, 122f2a) and the fixed frame (122e) on the connecting line of the second and fourth hinge points (122f1b, 122f2b) are arranged in a straight line, the position of the turning point may be such that the rotational motion of the display device (120) may not occur, or an unintended motion such as rotation in the reverse direction may occur.

[0132] In addition, in the first state, the first link (122f1) and the second link (122f2) may be arranged to be inclined downward toward one side relative to the fixed frame (122e). For example, the first link (122f1) and the second link (122f2) may be arranged to be inclined toward the side where the entrance (112) of the vehicle (110) is not formed in the first state.

[0133] Additionally, when the first link (122f1) is rotated 90 degrees, the support frame (122c) may be arranged to be inclined downward toward the other side. For example, when the first link (122f1) is rotated 90 degrees, the support frame (122c) may be arranged to be inclined downward toward the side where the entrance (112) of the vehicle (110) is formed.

[0134] In addition, when the first link (122f1) is rotated 90 degrees, the support frame (122c) on which the curved display (122a) is mounted can be formed to rotate 40 degrees. In addition, the second state in which the curved display (122a) is arranged to be inclined downward to expose the display controller (122d) can be formed in a state in which the first link (122f1) is rotated 90 degrees or more, as illustrated in FIG. 15.

[0135] For example, when the length of the first link (122f1) is 140 mm and the distance between the first hinge point (122f1a) and the third hinge point (122f2a) is 100 mm, the length of the second link (122f2) and the distance between the second and fourth hinge points (122f1b, 122f2b) can be calculated by the following equation.

[0136] L2=(F-Dcosθ)2+(S+Dsinθ)2

[0137] Here, S represents the length of the first link (122f1), F represents the distance between the first and third hinge points (122f1a, 122f2a), L represents the length of the second link (122f2), and D represents the distance between the second and fourth hinge points (122f1b, 122f2b).

[0138] According to the above formula, the length of the second link (122f2) can be set to 190 mm, and the distance between the second and fourth hinge points (122f1b, 122f2b) can be set to 50 mm.

[0139] According to the configuration of the vehicle system (100) as described above, the display device (120) is basically configured so that as the first link (122f1) rotates around the first and third hinge points (122f1a, 122f2a), the center of rotation of the display (122a) mounted on the support frame (122c) moves closer to the display (122a), thereby causing the display (122a) to rotate more and more. That is, the center of rotation of the display device (120) created when the extensions of the first and second links (122f2) meet is configured so that the center of rotation changes from a position farther away from the display (122a) to a position closer to the display (122a) as it changes from the first state to the second state.

[0140] In addition, the curved display (122a) of the display device (120) installed on the support frame (122c) is configured to be lowered to a certain height while maintaining the first state when moving relative to the fixed frame (122e) by the connection unit (122f) as illustrated in FIG. 15, and then rotated around the first to fourth hinge points (122f1a, 122f1b, 122f2a, 122f2b) without causing interference with the body (111b) to switch to the second state.

[0141] That is, the vehicle system (100) of the present invention can more easily install the display device (120) on the ceiling (111a) of the vehicle (110) by operating the connection unit (122f), or set the back of the curved display (122a, 123a) to be visible to the worker for maintenance of the installed display device (120). Accordingly, the convenience of work during installation and maintenance related to the display device (120) installed in the vehicle (110) can be greatly improved, and the work speed can also be greatly shortened.

[0142] Meanwhile, the above detailed description should not be construed as limiting in any respect and should be considered illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
