[0019] The internal structure of the mobile body of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings. The drawings used in the following description are schematic diagrams and do not necessarily reflect the actual objects. For the convenience of illustration and easy understanding, there are cases where the scale, aspect ratio, etc. are changed from the actual objects and exaggerated. The same or corresponding parts in the figures are marked with the same reference numerals, and their descriptions are not repeated.

[0020] (Internal Structure of Vehicle 10)

[0021] Figure 1 1 is a diagram showing an example of the internal structure of the vehicle 10 of the present embodiment. In the present embodiment, the vehicle 10 is used as a moving body for illustration, but the moving body is not limited to the vehicle 10. The moving body may include ships, airplanes, spacecraft, etc. in addition to the vehicle 10. In addition, the vehicle 10 is described as a bus, but it is not limited to this, and may be a private car, a taxi, or any other vehicle. Figure 1 In the figure, "front" indicates the front direction of the vehicle 10. "Rear" indicates the rear direction of the vehicle 10. "Up" indicates the direction opposite to the direction in which gravity acts. "Down" indicates the direction in which gravity acts.

[0022] like Figure 1 As shown, a plurality of seats, namely seats 3a to 3e, are provided inside the vehicle 10. Specifically, the vehicle 10 is provided with a front row seat 3a, a second row seat 3b, a third row seat 3c, a fourth row seat 3d, and a rear row seat 3e. Figure 1 There are five seats in the vehicle, but this is an example, and the number of seats is not limited to five.

[0023] In the present embodiment, the seats 3a to 3e are arranged along the bottom surface 2 inside the vehicle 10 in such a manner that the height of the seats relative to the horizontal plane gradually increases toward the rear direction of the vehicle 10. The "horizontal plane" mentioned here refers to a plane perpendicular to the direction in which gravity acts. In addition, the "height relative to the horizontal plane" can be defined as, for example, the height reaching the headrest of each seat with an arbitrary horizontal plane as a reference. In addition, as long as the height relative to the horizontal plane gradually increases when looking down at the seats 3a to 3e as a whole, the heights of any multiple seats relative to the horizontal plane can be the same. For example, in Figure 1 In the figure, the heights of seats 3a and 3b relative to the horizontal plane are the same, but if the seats 3a to 3e are viewed from above as a whole, it can be seen that the heights relative to the horizontal plane gradually increase. Of course, the heights of all seats relative to the horizontal plane may be different. Alternatively, when the heights of seats 3a to 3e relative to the horizontal plane are set to h1 to h5 respectively based on an arbitrary horizontal plane, h1<h2<h3<h4<h5.

[0024] Such an arrangement of the seats 3a to 3e may be expressed as “the seats 3a to 3e are arranged in a stepped manner toward the rear direction of the vehicle 10” or “the seats 3a to 3e are arranged inclined toward the rear direction of the vehicle 10”.

[0025] exist Figure 1 In the embodiment, the bottom surface 2 is formed in a stepped shape toward the rear direction of the vehicle 10 , but the present invention is not limited thereto and the bottom surface 2 may be formed to be inclined at a predetermined upward angle toward the rear direction.

[0026] Two rails (not shown) extending in the front-rear direction are laid on the ceiling 1 inside the vehicle 10 , and the plate-like plate member 4 is attached to these rails.

[0027] In the present embodiment, at least a portion of the plate 4 or at least a part of the plate 4 is tilted downward relative to the horizontal plane as it moves toward the front direction of the vehicle 10. As an example of a method for tilting the plate 4, a support member 5 for tilting the plate 4 at a predetermined angle is installed on the plate 4, and the support member 5 is engaged with the rail. The plate 4 may be composed of a single plate extending in the front-rear direction of the vehicle 10, or a plurality of plates may be arranged adjacent to each other in the front-rear direction of the vehicle 10, and the details will be described later.

[0028] A projection film (not shown) is attached to the surface of the plate 4, which is the surface visible from the passengers sitting on the seats 3a to 3e, and the image of the projector 6 installed inside the vehicle 10 can be projected onto the projection film. However, if the surface of the plate 4 itself is suitable for projection, the projection film is not necessarily required. The material of the plate 4 is not particularly limited, and it can be fiber, for example. The installation position of the projector 6 is not particularly limited, for example, Figure 1 Shown may be a side view of the interior of vehicle 10 .

[0029] It is described that at least part of the plate 4 or at least a portion of the plate 4 is tilted downward relative to the horizontal plane as it moves toward the front direction of the vehicle 10, but there are multiple modes of this tilt. Therefore, the tilt modes are described below separately in the case where the internal structure of the vehicle 10 is composed of multiple plates and the case where the internal structure of the vehicle 10 is composed of one plate.

[0030] (Inclination pattern when composed of multiple plates)

[0031] First, refer to Figure 2 , the tilting mode when the internal structure of the vehicle 10 is composed of a plurality of plates is described. For the names of the plurality of plates, such as Figure 2 As shown in FIG. 1 , the plates 4a, 4b, 4c, 4d, 4e, and 4f are sequentially referred to as plates 4a, 4b, 4c, 4d, 4e, and 4f from the front side of the vehicle 10. Figure 2 , an example is shown in which the internal structure of the vehicle 10 is composed of six plates. Plate 4a is the "starting plate" and plate 4f is the "last plate". Figure 2 In the figure, the ceiling 1 and the supporting member 5 are omitted, and only the plates 4a to 4f are shown.

[0032] You can Figure 2 As shown in the mode 1A, only the starting plate 4a among the multiple plates 4a to 4f is inclined downward relative to the horizontal plane. When the inclination angle at this time is set to θ1, the size of the inclination angle θ1 is not particularly limited, and it can be any angle as long as the passengers sitting on the seats 3a to 3e can see and hear the image projected at least on the plate 4a at a natural neck angle. In addition, for the plates other than the starting plate 4a, that is, the plates 4b to 4f, it is assumed that they are configured to be parallel to the horizontal plane along the ceiling 1 of the vehicle 10, but depending on the bus, the ceiling 1 may also be curved. In the case where the ceiling 1 is curved, the plates 4b to 4f may also be configured to draw a curve along the ceiling 1. That is, the plates 4b to 4f other than the starting plate 4a may not necessarily be configured to be parallel to the horizontal plane.

[0033] In addition, you can Figure 2As shown in mode 2A, in addition to the inclination of the starting plate 4a, the plates 4b and 4c are also inclined at the same inclination angle θ1 as the plate 4a. In this case, the plates 4d to 4f are arranged parallel to the horizontal plane. In addition, the combination with the starting plate 4a is not limited to this combination. It is also possible to construct the two plates 4a and 4b to be inclined at an inclination angle θ1. In this case, the plates 4c to 4f are arranged parallel to the horizontal plane. In addition, it is also possible to construct the four plates 4a to 4d to be inclined at an inclination angle θ1. In this case, the plates 4e and 4f are arranged parallel to the horizontal plane. In addition, it is also possible to construct the five plates 4a to 4e to be inclined at an inclination angle θ1. In this case, only the last plate 4f is arranged parallel to the horizontal plane.

[0034] In addition, you can Figure 2 As shown in the pattern 3A, all of the plurality of plate members 4a to 4f are inclined at an inclination angle θ1. In this case, there is no plate member arranged parallel to the horizontal plane.

[0035] In addition, if Figure 2 As shown in mode 4A, the inclination angle may also have two different angles. Plates 4a and 4b are inclined at an inclination angle θ2. In addition, plates 4c and 4d are inclined at an inclination angle θ1. Here, θ2>θ1. In this case, plates 4e and 4f are configured to be parallel to the horizontal plane. In this way, it is also possible to configure multiple plates 4a to 4f to be inclined at two different angles. In addition, the combination of plates is not limited to the combination shown in mode 4A. For example, it is also possible that the starting plate 4a is inclined at an inclination angle θ2, and the plate 4b is inclined at an inclination angle θ1. In this case, plates 4c to 4f are configured to be parallel to the horizontal plane. In addition, it is also possible that plates 4a to 4c are inclined at an inclination angle θ2, and plates 4d to 4f are inclined at an inclination angle θ1. In this case, there is no plate configured to be parallel to the horizontal plane. When one or more plates including at least the starting plate 4a among the plurality of plates 4a to 4f are set as the first plate group and one or more plates adjacent to the first plate group are set as the second plate group, the first plate group and the second plate group may be inclined downward relative to the horizontal plane.

[0036] Reference Figure 2 In the mode 4A, the plates 4a and 4b constitute the "first plate group", and the plates 4c and 4d constitute the "second plate group". The inclination angle θ2 of the first plate group relative to the horizontal plane is greater than the inclination angle θ1 of the second plate group relative to the horizontal plane. In addition, as described above, the "first plate group" can also be composed of one plate. Similarly, the "second plate group" can also be composed of one plate.

[0037] In addition, if Figure 2As shown in mode 5A, the inclination angle may also have three different angles. Plates 4a and 4b are inclined at an inclination angle θ3. In addition, plates 4c and 4d are inclined at an inclination angle θ2. In addition, plates 4e and 4f are inclined at an inclination angle θ1. Here, θ3>θ2>θ1. In this case, there is no plate configured to be parallel to the horizontal plane. In this way, it is also possible to configure a plurality of plates 4a to 4f to be inclined at three different angles. In addition, the combination of plates is not limited to the combination shown in mode 5A. For example, it is also possible that the starting plate 4a is inclined at an inclination angle θ3, the plate 4b is inclined at an inclination angle θ2, and the plate 4c is inclined at an inclination angle θ1. In this case, plates 4d to 4f are configured to be parallel to the horizontal plane. As long as one or more plates among the multiple plates 4a~4f, including at least the starting plate 4a, are set as the first plate group, one or more plates adjacent to the first plate group are set as the second plate group, and one or more plates adjacent to the second plate group are set as the third plate group, the first plate group, the second plate group and the third plate group are inclined downward relative to the horizontal plane.

[0038] Reference Figure 2 In mode 5A, plates 4a and 4b constitute the "first plate group", plates 4c and 4d constitute the "second plate group", and plates 4e and 4f constitute the "third plate group". The inclination angle θ3 of the first plate group relative to the horizontal plane is larger than the inclination angle θ2 of the second plate group relative to the horizontal plane. The inclination angle θ2 of the second plate group relative to the horizontal plane is larger than the inclination angle θ1 of the third plate group relative to the horizontal plane. In addition, as described above, the "first plate group" can also be composed of one plate. Similarly, the "second plate group" can also be composed of one plate. Similarly, the "third plate group" can also be composed of one plate. In addition, plates 4a to 4f can all be inclined at different angles. In this case, when the inclination angles of plates 4a to 4f are set to θ6, θ5, θ4, θ3, θ2, and θ1, θ6>θ5>θ4>θ3>θ2>θ1. The inclination angle of the starting plate 4a is the largest, and the inclination angle of the last plate 4f is the smallest.

[0039] As in Figure 2 As described in the embodiments 1A to 5A, in the present embodiment, when the internal structure of the vehicle 10 is composed of a plurality of plates 4a to 4f, at least the first plate 4a only needs to be inclined.

[0040] (Tilt mode when composed of one plate)

[0041] Next, refer to Figure 3 , the tilting mode when the internal structure of the vehicle 10 is composed of a single plate 4 will be described. Figure 3 In, also with Figure 2Likewise, illustration of the ceiling 1 and the supporting member 5 is omitted, and only the plate 4 is shown.

[0042] You can Figure 3 As shown in the mode 1B, the plate 4 is bent at at least one bending point 9a and tilted downward relative to the horizontal plane. Figure 2 The contents described in the mode 1A are the same as those described in the mode 1A, so the description is omitted. It is assumed that the remaining portion of the plate 4 except the inclined portion is arranged parallel to the horizontal plane along the roof 1 of the vehicle 10, but the roof 1 may be curved depending on the bus. In the case where the roof 1 is curved, the remaining portion of the plate 4 except the inclined portion may also be arranged to draw a curve along the roof 1. That is, the remaining portion of the plate 4 except the inclined portion may not necessarily be arranged parallel to the horizontal plane.

[0043] In addition, the position of the bending point 9a is not limited to Figure 3 The position shown in mode 1B can also be Figure 3 As shown in the pattern 2B, the bending point 9b is formed by bending the plate 4 at the center.

[0044] In addition, you can Figure 3 As shown in the pattern 3B, the plate 4 is configured to be not bent but to be inclined at an inclination angle θ1.

[0045] In addition, you can Figure 3 As shown in the pattern 4B, the plate 4 has two bending points 9c and 9d, and is bent at different angles at the bending points 9c and 9d. In this case, the inclination angle θ2 at the bending point 9c relative to the horizontal plane is larger than the inclination angle θ1 at the bending point 9d relative to the horizontal plane. In the pattern 4B, the remaining portion of the plate 4 except the inclined portion is arranged parallel to the horizontal plane along the roof 1 of the vehicle 10.

[0046] In addition, you can Figure 3 As shown in the pattern 5B, the plate 4 has two bending points 9c and 9d, is bent at different angles at the bending points 9c and 9d, and does not have a portion arranged parallel to the horizontal plane. In this case, the inclination angle θ3 at the bending point 9c relative to the horizontal plane is larger than the inclination angle θ2 at the bending point 9d relative to the horizontal plane. The inclination angle θ2 at the bending point 9d relative to the horizontal plane is larger than the inclination angle θ1 relative to the horizontal plane.

[0047] (Effect)

[0048] As described above, according to the internal structure of the vehicle 10 (an example of a moving body) of the present embodiment, the following effects can be obtained.

[0049] In the internal structure of the vehicle 10, plate-like plates 4a to 4f or plate 4 are arranged along the ceiling 1 inside the vehicle 10, and an image can be projected onto the plate. A plurality of seats 3a to 3e are arranged inside the vehicle 10 in such a manner that the height of the seats relative to the horizontal plane gradually increases in one direction. At least part of the plates 4a to 4f or at least part of the plate 4 is inclined downward relative to the horizontal plane as it moves in an opposite direction opposite to the one direction. An example of the "one direction" mentioned here is the rear direction of the vehicle 10, and an example of the "opposite direction opposite to the one direction" is the front direction of the vehicle 10.

[0050] According to the above structure, passengers sitting on the seats 3a~3e can see and hear the images projected onto the panels 4a~4f or the panel 4 arranged along the ceiling 1 at a natural neck angle even in the normal sitting state, that is, the seats 3a~3e are not tilted significantly or completely tilted, thereby realizing seeing and hearing while moving.

[0051] Furthermore, since the images projected onto the plates 4a to 4f or the plates 4 arranged along the ceiling 1 can be viewed and heard without tilting the seats 3a to 3e to a large extent or completely, it is not necessary to ensure a space for tilting the seats 3a to 3e. Thus, a large number of seats can be arranged, and the vehicle can be used when there are a large number of people. That is, more passengers can be boarded, and economical contributions can also be made.

[0052] Furthermore, by tilting at least some of the plates 4a to 4f or at least part of the plate 4, projection can be achieved that is directed toward the target of the sight line toward the front of the vehicle 10, thereby providing passengers with images with a more realistic feel.

[0053] In addition, the "horizontal plane" of "height relative to the horizontal plane" may also be referred to as the bottom plane or the first horizontal plane. In addition, the "horizontal plane" of "inclined toward the lower side relative to the horizontal plane" may also be referred to as the ceiling plane or the second horizontal plane. The position of the first horizontal plane relative to the vertical direction is lower than the position of the second horizontal plane relative to the vertical direction.

[0054] Furthermore, when the internal structure of the vehicle 10 is composed of a plurality of plates 4a to 4f, at least the first plate 4a in the front direction of the vehicle 10 among the plates continuous along the ceiling 1 may be inclined downward relative to the horizontal plane (see Figure 2 In addition, when the internal structure of the vehicle 10 is composed of a plate 4, the plate 4 may be bent at at least one bending point 9a or bending point 9b and tilted downward relative to the horizontal plane (see Figure 3 Mode 1B, 2B).

[0055] Even in the case of such a structure, the passenger can view and listen to the video at a natural neck angle, thereby achieving viewing and listening while moving.

[0056] Furthermore, when the internal structure of the vehicle 10 is composed of a plurality of plates 4a to 4f, all the plates 4a to 4f continuous along the ceiling 1 may be inclined downward relative to the horizontal plane (see Figure 2 In addition, when the internal structure of the vehicle 10 is composed of a single plate 4, the single plate 4 may be tilted downward relative to the horizontal plane without being bent (see Figure 3 Mode 3B).

[0057] Even if all the plates 4a to 4f are tilted or all the plates 4 are tilted as in the above-described configuration, a passenger can view and listen to images at a natural neck angle, thereby enabling viewing and listening while moving.

[0058] Furthermore, when the internal structure of the vehicle 10 is composed of a plurality of plates 4a to 4f, one or more plates including at least the plate 4a starting in the front direction of the vehicle 10 among the plurality of plates 4a to 4f are set as the first plate group and one or more plates adjacent to the first plate group are set as the second plate group, and the first plate group and the second plate group are inclined downward relative to the horizontal plane. Alternatively, the inclination angle of the first plate group relative to the horizontal plane may be greater than the inclination angle of the second plate group relative to the horizontal plane (see Figure 2 In addition, when the internal structure of the vehicle 10 is composed of a plate 4, the plate 4 is bent at two bending points 9c and 9d and tilted downward relative to the horizontal plane. Alternatively, when the two bending points 9c and 9d are set as the first bending point and the second bending point in order from the front direction of the vehicle 10, the inclination angle of the plate 4 at the first bending point relative to the horizontal plane is larger than the inclination angle of the plate 4 at the second bending point relative to the horizontal plane (see Figure 3 An example of the "first sheet group" mentioned here is shown in Figure 2 The two plates 4a and 4b described in the pattern 4A are shown as an example of the "second plate group". Figure 2 The two plates 4c and 4d described in the mode 4A are used. However, the "first plate group" may be composed of one plate, and the "second plate group" may be composed of one plate.

[0059] According to the above configuration, by changing the angle in the middle of the surface on which the video is projected, it is possible to realize a projection that replaces the space, thereby providing a new experience to the passengers.

[0060] [Other implementation methods]

[0061] In the above-mentioned embodiment, the shape of the surface on which the image of the projector 6 is projected is described as a planar shape in the plate materials 4a to 4f or the plate material 4, but the present invention is not limited to this. Figure 4 As shown in FIG. 1 , the shape of the plate 4a that is inclined downward relative to the horizontal plane is not a flat surface, but a curved surface. In addition, when the plate is composed of a single plate 4, the shape of the portion that is inclined downward relative to the horizontal plane may also be a curved surface. In this way, even if the shape of the surface on which the image of the projector 6 is projected is a curved surface, the passenger can view and listen to the image at a natural neck angle, thereby achieving viewing and listening while moving.

[0062] In the above-mentioned embodiment, an example of using the support member 5 to tilt at least part of the plates 4a to 4f or at least part of the plate 4 is described, but the tilting method is not limited to the method using the support member 5. For example, a telescopic frame may be provided between at least part of the plates 4a to 4f or at least part of the plate 4 and the rail, and at least part of the plates 4a to 4f or at least part of the plate 4 may be tilted by extending the frame. Alternatively, at least part of the plates 4a to 4f or at least part of the plate 4 may be tilted using a known mechanism composed of a combination of a gear and a connecting rod, and at least part of the plates 4a to 4f or at least part of the plate 4 may be tilted using a bracket.

[0063] In the above-mentioned embodiment, the example in which the seats 3a to 3e are arranged so that the sight lines of the seated passengers are directed toward the front of the vehicle 10 is described, but the present invention is not limited thereto. For example, the seats 3a to 3e may be arranged in a manner such that the sight lines of the seated passengers are directed toward the rear of the vehicle 10. In this case, the seats 3a to 3e may be arranged along the bottom surface 2 inside the vehicle 10 in such a manner that the height of the seats relative to the horizontal plane gradually rises toward the front direction of the vehicle 10. Furthermore, at least part of the plates 4a to 4f or at least part of the plate 4 may be configured so as to be inclined downward relative to the horizontal plane as it moves toward the rear direction of the vehicle 10. According to such a structure, even when the seats 3a to 3e are arranged so that the sight lines of the seated passengers are directed toward the rear of the vehicle 10, the passengers can view and listen to the images at a natural neck angle, thereby realizing viewing and listening while moving.

[0064] The present disclosure is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims. Modes obtained by appropriately combining the technical means disclosed in the embodiments are also included in the protection scope of the present disclosure.
