Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

(One embodiment)
1 to 7 show a bus having a vehicle structure according to an embodiment of the present invention.

Although the entire bus of this embodiment is not shown, as shown in the cross-sectional view of FIG. 7, the bus 1 of this embodiment has a space skeletal structure 12 mounted on a chassis 11 and the space skeletal structure 12 thereof. A vehicle body 10 in which the exterior panel 13 is covered is provided. A floor panel 14 and a plurality of rows of seats 15 are attached to the inside of the vehicle body 10.

The chassis 11 is a chassis in which a front chassis, a rear chassis, a central chassis, and a piping chassis are integrally combined, like the chassis disclosed in, for example, Japanese Patent Laid-Open No. 10-194165. It is not limited to the chassis structure.

As shown in FIG. 7, the spatial skeletal structure 12 includes a floor frame 21 that forms a skeletal structure of the floor of the vehicle body 10, and a fixed base frame that supports the floor frame 21 on the chassis 11 at a higher position above the tire T. 22, side pillars 23 on the left and right of the vehicle, beam members above and below the window (not shown in detail), and the like.

The exterior panel 13 is an outer plate of a decorative plate that is supported by the space skeletal structure 12 by welding or the like so as to cover the space skeletal structure 12 from the outside. The floor panel 14 is a floor plate that forms, for example, a flat floor surface 14a inside the vehicle body 10.

As shown in the schematic shape in FIG. 5, a plurality of rows of seats 15 are arranged in each row, for example, six seats 15 are aligned in the same direction. As shown in FIGS. The seat 15 includes a seat surface portion 51, a backrest portion 52, and a seat frame 53 having legs 53a and 53b. The orientation of the plurality of seats 15 in each row is the vehicle frontward direction in FIG. 5, but may be different. The seats 15 in each row are arranged at the same position in the vehicle front-rear direction, and the seats in a plurality of rows are arranged adjacent to each other in the vehicle left-right direction. The left and right seats 15 may not be adjacent to each other at the same position in the front-rear direction.

As shown in FIGS. 4(A), 4(B) and 5, the floor frame 21 includes a pair of center beams 31 and side beams 33 that extend in the longitudinal direction in the front and rear of the bus 1 and are parallel to each other. The center beam 31 and the side beams 33 include a plurality of cross beams 35 that are connected in parallel and integrally, and a plurality of diagonal members 36 that connect the connection points of the center beam 31, the side beams 33, and the cross beams 35. It is composed of. The center beam 31, the side beams 33, the cross beams 35, and the diagonal members 36 extend in the direction along the floor surface 14a of the floor panel 14 (floor surface direction) and form a plurality of skeletal members integrally coupled to each other. I am configuring. The floor frame 21 shown in these figures shows only a part of the vehicle front-rear direction.

Here, each pair of the center beam 31 and the side beam 33 is a plurality of longitudinal frame members that extend in the vehicle front-rear direction and are separated in the vehicle left-right direction, and the plurality of cross beams 35 respectively. Further, there are a plurality of parallel cross skeleton members that are substantially orthogonal to the side beams 33 and are spaced apart from each other in the vehicle front-rear direction.

The diagonal member 36 is a connecting point P1 of one of the cross beams 35 and the center beam 31 among four connecting points of the pair of adjacent cross beams 35 and the adjacent center beam 31 and side beam 33 on each of the left and right sides. And the connection point P2 of the other cross beam 35 and side beam 33 is connected.

Therefore, the inclination directions of the pair of diagonal members 36 with respect to the center beam 31, the side beam 33, and the cross beam 35 are opposite to each other before and after the connecting points P1 and P2 in the vehicle front-rear direction.

The seat frames 53 of the plurality of rows of seats 15 are fastened or fixed to the plurality of seat support modules 61 by bolts or the like, or welded.

As shown in a typical example in FIG. 3A, each seat support module 61 includes, for example, a pair of substantially parallel left and right support plates 62 having a length L in the vehicle front-rear direction and having the same length. The pair of support plates 62 are substantially orthogonal to each other, and have a pair of connecting plates 63 that integrally connect the support plates 62 to each other.

In addition, the left and right support plates 62 of each seat support module 61 have a front-rear length L that can be supported between each pair of cross beams 35 that are adjacent in the vehicle front-rear direction among the plurality of cross beams 35. , The left and right legs 53a and 53b of the seat 15 are separated from each other in the vehicle left-right direction with a center-to-center distance d corresponding to the distance. That is, the front-rear length L is set to be closer to or more than the separation distance L1 between each pair of cross beams 35 adjacent in the vehicle front-rear direction (L≧L1).

Further, between a predetermined number of seat support modules 61 arranged in the vehicle front-rear direction corresponding to the seats 15 in each row, for example, between the six seat support modules 61 in each row shown in FIG. The six support plates 62 adjacent to each other on the one side in the front and rear are integrally formed with each other or partially welded to each other so as to be integrally connected. The plurality of seat support modules 61 in each row are interlocked between the seat frames 53 and the floor frames 21 of the plurality of seats 15 by the plurality of sets of support plates 62 that are integrally connected to each other on the left and right sides. A pair of left and right seat mounting plates 65 (see FIGS. 4B and 5) for supporting the leg portions 53a and 53b of the row seat frames 53 on the floor frame 21 are formed.

More specifically, the pair of left and right seat mounting plates 65 that form the support plates 62 of the plurality of seat support modules 61 extend in the longitudinal direction while being separated from each other substantially in parallel, while the plurality of seat support modules 61 are provided. Are joined together in the plate width direction (shorter direction) by a plurality of sets of joining members 63 corresponding to. Then, each of the seat support modules 61 is formed in a substantially parallel beam shape by the corresponding module length section (section of a specific length L) of each pair of seat mounting plates 65 and each set of coupling members 63. .. As a result, with respect to various assumed seat specifications, each seat support module 61 is a seat attachment member having a predetermined strength that satisfies a predetermined technical standard for ensuring safety.

Each support plate 62 is formed of, for example, a plate-shaped steel material having a rectangular cross section as shown in FIG. 3B, or an inverted U-shaped or hat-shaped steel material as shown in FIG. 3C. The plurality of coupling plates 63 (coupling members) are made of a steel plate having a smaller cross-sectional area than the support plate 62, a grooved steel, a hat-shaped steel, or the like. Further, as shown in FIG. 4B, each support plate 62 has a plurality of stud bolts, bolt holes, etc. capable of fastening and positioning the leg portions 53a and 53b of the seat frame 53 of the corresponding seat 15 to the floor frame 21. Has a fastening and fixing portion 62a having a predetermined pitch.

The members forming each seat support module 61 are not limited to the support plate 62 and the connecting plate 63 in the illustrated example. Further, even when each seat support module 61 has a shape similar to that of the illustrated cross girder, the shape, the number, and the mutual arrangement posture of the members corresponding to the support plate 62 and the coupling plate 63 are not limited to those similar to the illustrated example. However, each seat support module 61 has the same dimension in the floor surface direction, for example, the length L in the vehicle front-rear direction and the lateral width W in the vehicle left-right direction. That is, the plurality of seat support modules 61 have the same shape having the same dimensions in the floor surface direction.

The front-rear length L here may be slightly shorter than the space distance between each pair of cross beams 35 adjacent to each other in the vehicle front-rear direction, as long as they can be integrally coupled by welding or the like. In other words, the front-rear length L may be equal to or more than the distance between the facing surfaces of the pair of cross beams 35 adjacent in the vehicle front-rear direction in the same direction. Of course, the front-rear length L may be larger than the distance between the facing surfaces of the pair of cross beams 35 adjacent in the front-rear direction of the vehicle in the same direction. In that case, when the cross-shaped seat support module 61 is embedded in the floor frame 21 so as to have substantially the same upper surface height, portions that overlap with each other and interfere with each other are generated. The cross-shaped seat support module 61 is partially cut out in advance so that it can be embedded at substantially the same height as the floor frame 21, and then the two are integrated.

Thereby, at least a part of the plurality of seat mounting plates 65 in the vehicle height direction is arranged within the installation range of the floor frame 21 in the vehicle height direction, and a part of the plurality of seat mounting plates 65 is on the floor. The plurality of seats 15 have a required rigidity with respect to the floor frame 21 while being integrated with a part of the center beam 31, the side beam 33, the cross beam 35, and the diagonal member 36, which are the frame members of the frame 21. A plurality of seat support modules 61 for fixed support are configured integrally with the floor frame 21.

In FIG. 5, an integral multiple of the front-rear length L corresponds to the distance between the cross beams 35 at the front and rear ends of the illustrated floor frame 21, but the floor frame 21 is configured to further extend in the vehicle front-rear direction. Alternatively, it may be integrally connected to another front and rear frame. Further, here, by using the left and right seat mounting plates 65 having a length that is a multiple of the front-rear length L or more, the plurality of seat support modules 61 are previously combined integrally in the front-rear direction, and the left and right seat mounting plates 65 are also combined. On the other hand, by forming the above-described partial notches in the height direction (thickness direction), the plurality of seat support modules 61 are embedded in the floor frame 21 having a skeletal structure and fixed by welding or the like. However, the left and right seat mounting plates 65 may be divided into front and rear depending on the arrangement of the seats and the position where they are connected to the floor frame 21.

Further, in FIG. 5, the lateral width W of each seat support module 61 corresponds to the separation distance w3 of the center beam 31 and the side beam 33 on each of the left and right sides of the floor frame 21. That is, the lateral width W of each seat support module 61 is such that when each seat support module 61 is embedded between the center beam 31 and the side beam 33 of the floor frame 21 at substantially the same upper surface height, It is set so that it can be fixed to the center beam 31 and the side beams 33 by welding or the like at both ends of the width W. However, the width W may be different from the distance w3 between the center beam 31 and the side beam 33. Although the length of the connecting plate 63 is equal to the lateral width W here, the plurality of connecting plates 63 are integrally connected in the same manner as the seat mounting plate 65 constitutes the plurality of supporting plates 62. Alternatively, the length of the connecting plate 63 may be different from the lateral width W and the separation distance w3.

The front-rear length L and the lateral width W of each seat support module 61, the plate widths of the plurality of support plates 62 in each seat support module 61 and their lateral separation distances d, and the plate widths and the front-rear separation distances of the plurality of coupling plates 63. As shown in FIGS. 6(A) and 6(B), no matter which position the seat support modules 61 are arranged on the floor frame 21, the seat support modules 61 are connected to the center beam 31 and the side beams. It is set to a value such that at least two members of the beam 33, the cross beam 35, and the diagonal member 36 can fix and support the floor frame 21 at three or more places.

As described above, in the present embodiment, each of the seat support modules 61 has the front-rear length L and the lateral width W that can be stably supported by the floor frame 21, and is separated from each other in the vehicle left-right direction, for example, a pair. Support plate 62 and a plurality of, for example, a pair of connecting plates 63 that integrally connect the plurality of supporting plates 62 to each other. A plurality of seat support modules 61 are integrally connected to the floor frame 21, and a plurality of sets of support plates 62 are connected to the front and rear of the floor frame 21, so that the center beam 31, the side beam 33, and the cross beam 35 of the floor frame 21 are connected. Between the diagonal members 36, the floor panel 14 (floor plate) on the floor frame 21 is integrally supported with the floor frame 21, and the corresponding plurality of seats 15 are also supported. That is, the floor frame 21, the plurality of seat mounting plates 65, and these and the plurality of connecting plates 63 form the same floor plate supporting surface F (see FIG. 7) that supports the floor panel 14.

In FIG. 5, the gap distance d1 between the plurality of support plates 62 in the vehicle left-right direction and the distance d between the centers are the lateral widths w1 and w2 of the center beams 31 and the side beams 33 in the vehicle left-right direction. Is set to a value greater than.

Further, the separation distance w3 between the facing surfaces of the plurality of center beams 31 and side beams 33 in the vehicle left-right direction of the floor frame 21 shown in FIG. 5 is the separation distance d2 of the outer edges of the plurality of support plates 62 in the vehicle left-right direction. And a value close to the lateral width W of the seat support module 61, which is larger than the distance d between the centers and slightly larger than the lateral width W.

Next, the operation will be described.

In the present embodiment configured as described above, a part of the plurality of seat mounting plates 65 is different from the center beam 31, the side beam 33, the cross beam 35, and the diagonal member 36, which are the plurality of skeletal members of the floor frame 21. A plurality of seat supporting modules 61 for fixedly supporting the plurality of seats 15 with respect to the floor frame 21 with a required rigidity in a state of being integrated with a part thereof. It is embedded and integrated to the height.

Therefore, even though the vehicle body 10 having the floor frame 21 is provided, even if the user has a special seat shape or seat arrangement of the seat 15, each seat support module is the same as the standard seat specification or seat arrangement. While fixing the seat to 61, the seat support module 61 can be embedded and integrated with the floor frame 21 at a position corresponding to the required seat arrangement so as to have substantially the same upper surface height. The vehicle structure has a seat mounting strength that can ensure safety.

As a result, even though the vehicle body 10 having the floor frame 21 having a skeletal structure is provided, it is possible to cope with a user's own seat or seat arrangement at low cost and in a short time, and yet to ensure safety, the bus 1 having a vehicle structure. Can be provided.

In addition, in the present embodiment, the plurality of seat support modules 61 have the same shape having the same dimensions in the surface direction (floor surface direction) of the floor surface 14a and the floor plate support surface F. Therefore, regardless of the arrangement of the seats 15, the vehicle structure is such that the seat mounting strength that can ensure the safety of each seat 15 can be ensured by the corresponding seat support module 61.

Further, in the present embodiment, the plurality of seat mounting plates 65 are integrally coupled to each other in the lateral direction by the plurality of sets of coupling members 63 corresponding to the plurality of seat supporting modules 61, respectively. However, the plurality of support plates 62 that are the specific length sections of the plurality of seat mounting plates 65 that are the sections of the corresponding front-rear length L and the coupling members 63 of each set form a substantially cross beam shape. Therefore, the plurality of seat support modules 61 integrally connected to the floor frame 21 can be easily and lightly manufactured to have a required strength.

In addition, the plurality of seat support modules 61 support the floor panel 14 on the floor frame 21 by the plurality of seat mounting plates 65 (a plurality of sets of support plates 62) integrally connected to the floor frame 21, and Parallel seat tracks M1 and M2 (see FIG. 3A) that support the seat 15 are formed. Therefore, it is possible to secure a sufficient degree of freedom in the arrangement of the seat 15 and each seat support module 61 in the vehicle front-rear direction with respect to the floor frame 21.

In addition, in the present embodiment, each of the seat support modules 61 has a front-rear length that is close to or more than the distance L1 between the pair of cross beams 35 that are adjacent to each other in the vehicle front-rear direction. The mounting strength of each seat 15 with respect to the seat support module 61 can be sufficiently ensured by the corresponding seat support module 61, and in combination with the floor frame 21 having the diagonal member 36, the degree of freedom of arrangement of each seat support module 61 is increased. You can secure enough.

Moreover, in the present embodiment, the gaps d1 between the plurality of support plates 62 in the vehicle left-right direction are larger than the lateral widths w1 and w2 of the center beams 31 and the side beams 33 in the vehicle left-right direction, respectively. A separation distance w3 between the facing surfaces of the beam 31 and the side beam 33 facing each other in the vehicle left-right direction is larger than a separation distance d2 of the outer edges of the plurality of support plates 62 in the vehicle left-right direction.

Therefore, the degree of freedom in arranging the plurality of seat support modules 61 with respect to the floor frame 21 in the vehicle left-right direction can be increased.

Further, in the present embodiment, the floor frame 21 having a skeletal structure, the plurality of sets of support plates 62 of the plurality of seat support modules 61, and the plurality of sets of coupling plates 63 support the same floor panel 14. Since F is formed, even if a plurality of seats 15 are attached to the floor frame 21 having a skeletal structure via a plurality of seat supporting modules 61, the installation height of the floor panel 14 is the arrangement of the plurality of seat supporting modules 61. Therefore, it is possible to suppress the increase in the height, and it is possible to secure the required seat support rigidity without narrowing the space of the passenger compartment 17.

As a result, no matter where the seat support modules 61 are arranged on the floor frame 21, the seat support modules 61 are provided with at least two members of the center beam 31, side beams 33, cross beams 35, and diagonal members 36. Accordingly, the floor frame 21 can be fixed and supported at three or more places, and a flexible seat layout for the vehicle body 10 is possible.

As described above, in the present embodiment, the seat support module 61 common to the seats 15 is configured, and the seat support module 61 can be arranged at a desired position of the floor frame 21, so that the floor frame 21 supported by the chassis 11 can be disposed. In a bus 1 equipped with a vehicle body 10 having a vehicle body, it is possible to deal with a seat 15 and its seat arrangement based on a user's unique specification at low cost and in a short time, and at the time of a collision required by the bus 1. It is possible to provide a bus having a vehicle structure having a required seat mounting strength capable of ensuring safety such as.

(Other embodiments)
FIG. 8 shows a bus having a vehicle structure according to another embodiment of the present invention.

The floor frame of this embodiment is different from that of the above-described embodiment, but the other configurations are the same as those of the embodiment. Therefore, hereinafter, with respect to the same or similar configuration as that of the one embodiment, the different points from the one embodiment will be described by using the reference numerals of the corresponding constituent elements in FIGS. 1 to 7.

In the bus 1 according to the present embodiment, the spatial skeletal structure 12 serves as the floor of the vehicle body 10 and has a skeleton structure as shown in FIG. 8, and the floor frame 71 above the tire T on the chassis 11. It includes a fixed base frame 22 that is supported at a high position, side pillars 23 on the left and right of the vehicle, and beam members (not shown) above and below the window.

In addition, as shown in FIG. 8, a plurality of sets of support plates 62 of each of the plurality of seat support modules 61 have a pair of cross beams adjacent to each other in the vehicle front-rear direction on both end sides in the vehicle front-rear direction (the left-right direction in FIG. 8). 35 (cross frame members), and the plurality of coupling plates 63 of each of the plurality of seat support modules 61 are adjacent to each other in the vehicle left-right direction on both sides of the center beam 31 and the side beam 33 (side beam 33). It is welded to a pair of longitudinal frame members.

Further, the support plate 62 and the coupling plate 63 of a part of the seat support module 61 are partially cut out to be constituted by a part of the diagonal member 36 and welded to the diagonal member 36.

Also in the present embodiment, the plurality of seat support modules 61 support the floor panel 14 on the floor frame 71 and the plurality of seats 15 by the plurality of sets of support plates 62 integrally coupled to the floor frame 71. doing.

In the present embodiment, each seat support module 61 is illustrated as having a pair of support plates 62 and a pair of connecting plates 63 in the drawings, but the number of these supporting plates 62 and the connecting plates 63 and their mutual connection are shown. Needless to say, the posture is not particularly limited, and the pair of support plates 62 may not be parallel to each other or may intersect.

Further, the case where the floor frames 21, 71, the plurality of support plates 62, and the plurality of coupling plates 63 configure the same substantially flat floor plate support surface F has been illustrated, but the floor plate support surface F is not flat and the vehicle height direction is high. It may have irregularities. Although the bus 1 is illustrated as a high-decker vehicle, the present invention is not limited to the same floor surface height even if it has a spatial skeletal structure as shown in FIG. 9 or a lower floor. It goes without saying that it can be applied.

Furthermore, in each of the above-described embodiments, the plurality of seats 15 are arranged to face the front of the vehicle, but the seats 15 may have different directions, for example, diagonally frontward. It goes without saying that the shape of the seat 15 and the presence/absence of a movable part are arbitrary.
