Description

VEHICLE SYSTEM

The present invention relates to a vehicle system in which a display is applied to a ceiling area inside.

A vehicle system refers to a means of transportation that moves people or objects along a ground path to a destination. As autonomous driving and eco-friendly vehicle technologies advance, vehicle systems are being developed in various ways to implement various forms of eco-friendly autonomous driving mobility that drive automatically without a person directly driving. In addition, displays that provide various information to passengers can be installed in the vehicle system.

Meanwhile, the Korean Patent Publication (KR 10-2371608 B1, published on March 7, 2022) discloses a vehicle having a display system configured to change the position of an image output from a display according to the suspension height of the driver's seat. However, the display system disclosed in this patent document provides information only to specific vehicle passengers, such as the driver, so other passengers in the vehicle have difficulty receiving information through the display.

Accordingly, development of a vehicle system that can more effectively convey information through displays, especially to all passengers of autonomous, unmanned vehicles, may be considered.

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.

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

The vehicle (110) is a transportation vehicle that moves people or objects to a destination. In the drawings of the present invention, the vehicle (110) is depicted as a form of mobility that moves on the ground, but may also be formed as a form of mobility that can move in the sky, such as UAM (Urban Air Mobility). In addition, the vehicle (110) may be formed to provide various services to the passengers (P) while moving, in addition to the purpose of simply moving the passengers (P) to the destination. For example, the vehicle (110) may be provided with facilities for providing healthcare, meals, entertainment, and education services.

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, as illustrated in FIG. 4, image information about the surroundings of the entrance (112) of the vehicle (110) when the vehicle (110) is stopped, and a message informing 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), a stop schedule message, etc. may be included. In addition, the vehicle system (100) may further include a side display formed to be arranged on the side of the interior of the vehicle (110) and to provide visual information to the passengers (P), as illustrated in FIG. 3.

The display device (120) includes a flat display module (121), a first curved display module (122), and a second curved display module (123). The 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). The peripheral area of the display device (120) may be arranged to be partially covered by the headlining (111a) of the vehicle (110), as illustrated in FIG. 2.

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).

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).

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

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

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).

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

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

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) forms a single flat surface 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). In addition, the two ends of the display device (120) form curves by bending the first and second curved portions of the first and second curved display modules (122, 123) downwardly.

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).

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.

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

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

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

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).

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).

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 shown in FIGS. 4 and 5, the first and second curved portions (122a2, 123a2) can provide the passenger (P) with visual information that informs the vehicle's (110) entrance (112) to be opened when the vehicle is stopped. 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.

Additionally, the visual information output from the first and second planes (122a1, 123a1) may be related to the visual information output from the plane (121a1) of the flat display module (121).

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).

According to the configuration of the vehicle system (100) described above, 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).

Meanwhile, the conventional method of manufacturing a curved display uses a jig to create the curvature of the display, mounts a flex bar on the back of the display, and mounts the display on a counterpart using the flex bar. At this time, the curvature shape created by the jig is maintained by the frictional force through the screw fastening on the side of the flex bar. In addition, since the curvature is maintained by the frictional force through the 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. In addition, since a TV box weighing about 3.5 kg is mounted on the back of the curved display, there is a risk of damage to the display. In addition, in the conventional method of manufacturing a curved display using a jig, the curvature of the display can be created only at a constant curvature, and it is difficult to apply a different curvature to only some sections. In order to solve these conventional problems, the present invention proposes a new type of curved display installation structure.

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

FIG. 7 is a perspective view showing the display device (120) shown 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) shown in FIG. 7 operates and the display controller (122d) is exposed. FIG. 9 is a perspective view showing the flat display module (121) shown in FIG. 7. FIG. 10 is a perspective view showing the first curved display module (122) shown in FIG. 7. FIG. 11 is a diagram showing the process of manufacturing the first curved display module (122) shown in FIG. 10.

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) formed to control the flat display (121a) and the curved display (122a, 123a), respectively. As shown in FIG. 9, a first frame (121b) and a second frame (121c) formed to be mutually supported by the first frame (121b) may be mounted on the back surface of the flat display (121a). The display controller (121d) of the flat display module (121) may be installed in the second frame (121c).

Meanwhile, the first and second curved display modules (122, 123) are arranged on the front and rear sides of the flat display module (121), respectively, and most of their technical features are the same or similar except for the different positions of their arrangement. 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.

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).

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 of it supports the curved support portion (122b2b) of the first bracket (122b1) and the curved support portion (122b2b) of the second bracket (122b2).

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).

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.

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

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 one of the second cross frame portions to reinforce the prevention of twisting of the curved support portion (122b1b, 122b2b).

In addition, the display controller (122d) can be mounted on the second cross frame portion (122c3). The second cross frame portion (122c3) is arranged 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.

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 portion of a curved display (122a) into a curved portion using a jig.

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).

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).

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

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 the correct 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 assemblability with the counterpart can be improved. In addition, since the display controller (122d) is mounted on the support frame (122c), the display device (120) is not subject to strain even in an environment where continuous impact and vibration occur, such as a vehicle (110), and thus the durability of the display device (120) can be greatly improved.

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 such 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 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).

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

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 as seen 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.

Referring to FIGS. 12 to 15, a display device (120) of a vehicle system (100) includes a display (121a, 122a, 123a) that outputs visual information, a plurality of brackets (122b) mounted on the back surface of the displays (121a, 122a, 123a), a support frame (122c) coupled with 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.

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) in 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), centered on the flat display module (121).

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

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

In addition, the display (121a, 122a, 123a), for example, the curved display (122a) of the first curved display module (122), may be configured to 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 downward 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).

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

The locking portion (122e1) may be formed to limit relative movement by locking the support frame (122c) in the first state in which the display (121a, 122a, 123a), for example, the curved display (122a) of the first curved display module (122), 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.

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

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

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

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).

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

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).

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).

In addition, 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 located below the first hinge point (122f1a) and the third hinge point (122f2a).

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

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 turning point position may be reached, and the display device (120) may not rotate, or an unintended operation, such as rotation in the reverse direction, may occur.

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.

In addition, 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.

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.

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.

L ² =(F-Dcosθ) ² +(S+Dsinθ) ²

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).

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.

According to the configuration of the vehicle system (100) as described above, basically, 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 moves 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.

In addition, the curved display (122a) of the display device (120) installed in the support frame (122c) is 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 rotates around the first to fourth hinge points (122f1a, 122f1b, 122f2a, 122f2b) without causing interference with the body (111b) to switch to the second state.

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.

Meanwhile, the above detailed description should not be construed as restrictive 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 included in the scope of the present invention.
