Description

[Technical field]

[0001] The present invention relates to rail vehicles, and more particularly to rail vehicles having continuous horizontal windows in laser-welded side panels. [Background technology]

[0002] In recent years, railroad cars with excellent aesthetic appearance have been developed for express trains and the like, for example, by using stainless steel plates for the side panels of the car body and laser welding the side panels to reinforcing cross beams. Conventionally, side windows formed on such laser-welded side panels have side panels that are laser-welded to the winding section, so the window glass is largely divided by the side panels, and the window is not continuous in the longitudinal direction of the car, resulting in problems with the aesthetics and design of the car's exterior. To solve this problem, for example, Patent Document 1 discloses a railroad car in which a continuous window is formed on the side panels by providing a side pillar structure as described below.

[0003] That is, as shown in Figures 13 to 15, in the railway vehicle 100 of Patent Document 1, a side pillar structure 106 of a vehicle body structure 101K is provided at the winding portion 102H of a continuous window 102 provided in the side portion 101 of the vehicle, which supports the side portion 101 in the vertical direction (the up-down direction of the vehicle). This side pillar structure 106 includes an upper side pillar 106a extending upward from the vehicle from a cross frame 104 of the vehicle body structure 101K arranged above the continuous window 102, and a lower side pillar 106b extending downward from a cross frame 105 of the vehicle body structure 101K arranged below the continuous window 102. A window side pillar 106c is arranged between the upper side pillar 106a and the lower side pillar 106b, and is located on the vehicle inner side of the upper side pillar 106a and the lower side pillar 106b. The window side pillar 106c, the upper side pillar 106a, and the lower side pillar 106b are connected together by a side pillar auxiliary member 106d.

[0004] Then, side panels 107 are attached to the outer sides of the upper side pillars 106a and lower side pillars 106b, and a windscreen panel 108 is attached to the window side pillars 106c. In addition, reinforcing members 109 for holding the glass panels 102a, 102b, and 102c of the continuous window 102 are attached to the window opening 103 sides of the cross beams 104 and 105. Furthermore, when installing the glass plates 102a, 102b, and 102c in the window opening 103, the glass plates 102a, 102b, and 102c are each fitted into a recess 110 formed by a side outer plate 107 supported by the upper side pillar 106a and the lower side pillar 106b, and a wind-up plate 108 supported by the window side pillar 106c, and the glass plates 102a, 102b, and 102c are each airtightly installed to the reinforcing members 109 attached to the cross beams 104 and 105 and the wind-up plate 108 via a sealant 111. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 7-4237 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the railway vehicle 100 of the above-mentioned Patent Document 1 has the following problem. That is, in the above-mentioned side pillar structure 106, the upper side pillar 106a, the lower side pillar 106b, and the window side pillar 106c are integrally connected by the side pillar auxiliary member 106d provided on the inside of the vehicle from each of the side pillars 106a, 106b, and 106c, and a side outer plate 107 is attached to the outside of the vehicle of the upper side pillar 106a and the lower side pillar 106b, and a wind-over plate 108 is attached to the window side pillar 106c. Therefore, it is necessary to previously connect each of the side pillars 106a, 106b, and 106c integrally by the side pillar auxiliary member 106d provided on the inside of the vehicle and attach the wind-over plate 108 to the window side pillar 106c, and then attach the side outer plate 107 to the outside of the vehicle of the upper side pillar 106a and the lower side pillar 106b.

[0007] However, since this side column structure 106 is manufactured by joining multiple components (106a, 106b, 106c, 106d) by spot welding or the like, twisting and deformation of the entire side column is likely to occur during joining, which poses the problem that it is difficult to join the upper side column 106a to the side outer plate 107, and the lower side column 106b to the side outer plate 107 by laser welding, which has strict construction conditions in terms of equipment.

[0008] The present invention has been made to solve such problems, and has an object to provide a railway vehicle in which side exterior panels made of stainless steel can be easily laser welded, and in which the aesthetic and design aspects of the joint sections that support the glass panels of the continuous windows formed on the side exterior panels can be improved. [Means for solving the problem]

[0009] In order to achieve the above object, a railway vehicle according to the present invention has the following configuration. (1) A railway vehicle using stainless steel plates for the side outer panels of a car body and having a horizontally long continuous window formed continuously in the longitudinal direction of the car on the side outer panels, The side outer plate is laser-welded from the inside of the vehicle along the vehicle longitudinal direction to a plurality of cross bones arranged on the inside of the side outer plate, The cross frame is joined to a cross beam plate disposed on the vehicle interior side from the cross frame at the wind-up portion of the continuous window and extending in the vehicle up-down direction from the uppermost cross frame to the lowermost cross frame, The wind-collecting plate is connected to a vertical frame disposed on the vehicle inner side from the upper end to the lower end of the wind-collecting plate in the vehicle up-down direction, The glass panels of the continuous window are divided along the vertical direction of the vehicle within the range of the continuous window of the windshield, and the seams of each divided glass panel are connected to the windshield via a sealing member.

[0010] In the present invention, the side outer panel is laser welded from the inside of the vehicle along the longitudinal direction of the vehicle to a plurality of cross bones arranged on the inside side of the side outer panel, so that the weld bead (back bead) does not appear on the outer surface of the side outer panel, improving the aesthetic appearance of the vehicle while increasing the strength of the side outer panel in the longitudinal direction of the vehicle.

[0011] In addition, the cross frame is joined to a cross beam plate that is disposed on the inside of the cross frame at the winding portion of the continuous window and extends in the vertical direction of the vehicle from the top cross frame to the bottom cross frame, and the winding plate is joined to a vertical frame that is disposed on the inside of the cross frame and extends in the vertical direction of the vehicle from the upper end to the lower end of the winding plate. Therefore, all the cross frames located above the continuous window and all the cross frames located below the continuous window can be connected on the inside of the vehicle by the winding plate and the vertical frame at the intermediate portion of the continuous window in the longitudinal direction of the vehicle. This makes it possible to reinforce the side outer plate forming the horizontally long continuous window from the inside of the vehicle with a simple structure. The winding plate that is joined to the vertical frame is joined to the cross frame that is laser welded to the side outer plate. Therefore, the side outer plate is not easily affected by thermal distortion, etc., when the vertical frame and the winding plate are joined, and the aesthetic appearance of the side outer plate can be maintained.

[0012] In addition, the glass panes of the continuous window are divided along the vertical direction of the vehicle within the range of the continuous window of the winding plate, and the joints of each divided glass pane are connected to the winding plate via a sealing member, so that each glass pane of the continuous window is supported from the inside of the vehicle by the winding plate reinforced with vertical ribs. Therefore, the outer surfaces of each glass pane of the continuous window can be formed to be approximately flush with each other, sandwiching a sealing member that fills the minute gaps of the joints. Furthermore, the glass panes are not largely divided by the side outer panels. As a result, the continuous window is formed continuously in the longitudinal direction of the vehicle, and the aesthetic and design qualities of the vehicle exterior can be improved.

[0013] Therefore, according to the present invention, a railway vehicle can be provided in which stainless steel side panels can be easily laser welded, and the aesthetics and design of the joint parts that support the glass panels of the continuous window formed on the side panels can be improved.

[0014] (2) In the case of a railway vehicle as described in (1), The glass plate is divided at both ends in the vehicle longitudinal direction within the continuous window of the windshield plate, The vertical bones are joined to both ends of the siding.

[0015] In the present invention, the glass plate is divided at both ends in the longitudinal direction of the vehicle within the continuous window of the soffit plate, and the vertical ribs are joined to both ends of the soffit plate, so that the joints of each divided glass plate can be connected to both ends of the soffit plate, which are strongly reinforced by the vertical ribs, via sealing members. Therefore, each divided glass plate can be more stably connected to the soffit plate, and a continuous window with excellent aesthetics that is longer in the longitudinal direction of the vehicle can be formed. In addition, the glass plate can be divided into a glass plate for soffit facing the soffit plate and a glass plate for observation, which allows the view outside the vehicle to be seen from the passenger compartment, and the area of ​​the glass plate for soffit can be made smaller than the area of ​​the glass plate for observation. This makes it possible to reduce the weight of the entire glass plate by making the thickness of the glass plate for soffit thinner than the thickness of the glass plate for observation, which is also advantageous in terms of cost. As a result, it is possible to form a continuous window with excellent aesthetics that is longer in the longitudinal direction of the vehicle, while promoting weight reduction and cost reduction of the vehicle.

[0016] (3) In the case of railway vehicles described in (2), The sealing member is characterized by comprising a pair of sponge-like first synthetic rubber plates connected to the peripheral portions of the joints of the glass plates, a sealant filled in the gaps at the joints and in the gaps between the first synthetic rubber plates, and a second synthetic rubber plate connecting the first synthetic rubber plates and the sealant to the gathering plate.

[0017] In the present invention, the sealing member comprises a pair of sponge-like first synthetic rubber plates connected to the peripheral edges of the joints of the glass plates, a sealant filled in the gaps at the joints and in the gaps in the first synthetic rubber plates, and a second synthetic rubber plate connecting the first synthetic rubber plate, the sealant, and the windscreen plate. Therefore, by surrounding the sealant filled in the gaps at the joints of the glass plates with the first synthetic rubber plate and the second synthetic rubber, even if there is a difference in plate thickness between the windscreen glass plate facing the windscreen plate and the observation glass plate through which the view outside the vehicle can be seen from the passenger compartment, the difference in plate thickness can be absorbed, reducing the difference in level on the outer surface of the vehicle between the windscreen glass plate and the observation glass plate, thereby further improving the aesthetics of the continuous window.

[0018] (4) In a railway vehicle according to any one of (1) to (3), The upper and lower ends of the glass plate are fitted into a sealing elastic member and are pressed and adhered to cross beams joined to the upper and lower ends of the continuous window by a glass holder extending in the longitudinal direction of the vehicle.

[0019] In the present invention, the upper and lower ends of the glass sheets, fitted into the sealing elastic member, are pressed and bonded to the cross frame joined to the upper and lower ends of the continuous window by the glass holder extending in the longitudinal direction of the vehicle, so that each divided glass sheet can be pressed and bonded continuously to the cross frame by the common glass holder extending in the longitudinal direction of the vehicle. This reduces the variation in the step between each glass sheet and the side outer panel, and further improves the aesthetics of the side outer panel forming the continuous window. Effect of the Invention

[0020] According to the present invention, it is possible to provide a railway vehicle in which the side panels made of stainless steel can be easily laser welded, and in which the aesthetic and design aspects of the joint portion that supports the glass panes of the continuous window formed in the side panels can be improved.

[0022] <Configuration of this railway vehicle> Next, a railway vehicle according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0023] FIG. 1 shows a schematic side view of a railway vehicle according to one embodiment of the present invention. As shown in FIG. 1, the railway vehicle 10 of this embodiment uses a stainless steel plate SK as a side outer plate 1 of the car body ST, and is provided with a horizontally long continuous window 2 formed continuously in the longitudinal direction of the car on the side outer plate 1. The stainless steel plate SK is preferably an austenitic stainless steel plate that is high in strength and can be made lightweight, and is formed with a plate thickness of about 2 mm. The car body ST is provided with an underframe DW supported by a bogie DS running on a rail RL, a side structure GK rising upward from both ends of the underframe DW on the outer side of the car in the inside-outside direction of the car, an end structure TK rising upward from both ends of the underframe DW in the longitudinal direction of the car, and a roof structure YK connected to the upper ends of the side structure GK and the end structure TK. The side structure GK has a side door GT for boarding and alighting formed at a position near the end structure TK. In FIG. 1, there is one side door GT, but there may be more than one.

[0024] The side structure GK is divided into a plurality of side structure blocks GK1, GK2, and GK3 in the longitudinal direction of the vehicle, and the side structure blocks GK1, GK2, and GK3 are joined at boundaries (not shown). A horizontally long continuous window 2 is formed in the side outer plate 1 arranged on the outer side of the side structure GK. The continuous window 2 is formed, for example, in a horizontally long, approximately rectangular shape between one end structure TK and the side door GT. The side outer plate 1 includes a curtain portion 1a located above the continuous window 2 on the vehicle and a waist portion 1b located below the continuous window 2 on the vehicle.

[0025] 2 shows a partial side view of the A part of the side structure shown in FIG. 1 as seen from the inside of the vehicle (the vehicle inner side). FIG. 3 shows the BB cross section shown in FIG. 2. FIG. 4 shows a perspective view of the C part shown in FIG. 2. FIG. 5 shows a perspective view of the D part shown in FIG. 2. As shown in FIG. 2 to FIG. 5, the side structure GK is provided with upper cross beams 3 (3a, 3b, 3c) of the hat-shaped cross section window, which are arranged in parallel on the vehicle inner side of the side outer plate 1 and spaced apart from each other above the continuous window 2, and lower cross beams 4 (4a, 4b, 4c, 4d, 4e) of the hat-shaped cross section window, which are arranged in parallel on the vehicle inner side of the side outer plate 1 and spaced apart from each other below the continuous window 2. Each cross beam 3, 4 is formed to have a length substantially equal to the length of each side structure block GK1, GK2, GK3 in the vehicle longitudinal direction, and is arranged parallel to each other. Each of the cross bones 3, 4 is formed by bending a steel plate (for example, a stainless steel plate) having a thickness of about 1 to 3 mm into a hat-shaped cross section of approximately the same height.

[0026] The side panel 1 is laser welded from the inside of the vehicle to a plurality of cross bones 3, 4 arranged on the inside of the vehicle from the inside of the vehicle in the longitudinal direction of the vehicle. Here, the side panel 1 is laser welded to the flanges 31, 41 of the cross bones 3, 4 in a two-ply state. Therefore, the weld bead (back bead) does not appear on the outer surface of the side panel 1, and the strength of the side panel 1 in the longitudinal direction of the vehicle can be increased while improving the aesthetic appearance of the vehicle. The cross bone 3 located above the continuous window 2 is located near the window upper end 21 of the continuous window 2 and the upper end 11 of the side panel 1 (curtain portion 1a), and is arranged in parallel between them with a space therebetween in the vertical direction. The cross bone 4 located below the continuous window 2 is located near the window lower end 22 of the continuous window 2 and the lower end 12 of the side panel 1 (waist portion 1b), and is arranged in parallel between them with a space therebetween in the vertical direction. The lower end 12 of the side panel 1 (waist portion 1b) is joined to the underframe DW. Therefore, the cross beams 3, 4 can be accurately overlapped with the curtain portion 1a and waist portion 1b of the side panel 1. Furthermore, a predetermined space is formed between the cross beams 3 above adjacent windows and between the cross beams 4 below adjacent windows, allowing the laser beam RB to move linearly in the longitudinal direction of the vehicle. Therefore, the cross beams 3, 4 can be stably set with no gaps with respect to the curtain portion 1a and waist portion 1b of the side panel 1, and high-quality laser welding can be performed.

[0027] In addition, the cross beams 3, 4 are joined to a cross beam plate 5 arranged on the inside of the vehicle from the cross beams 3, 4 at the cross beam portion 2H of the continuous window 2, and extending in the vertical direction of the vehicle from the uppermost cross beam 3c to the lowermost cross beam 4e. The cross beam plate 5 is also joined to a vertical beam 6 arranged on the inside of the vehicle from the cross beam plate 5 to the upper end 51 of the cross beam plate 5 to the lower end 52 of the cross beam plate 5. Therefore, all the cross beams 3 located above the continuous window 2 and all the cross beams 4 located below the continuous window 2 can be connected on the inside of the vehicle by the cross beam plate 5 and the vertical beam 6 at the intermediate portion of the continuous window 2 in the longitudinal direction of the vehicle. This makes it possible to reinforce the side outer plate 1, which is formed by laser welding the horizontally long continuous window 2, from the inside of the vehicle with a simple structure. The vertical beam 6 is formed, for example, by bending a steel plate (for example, a stainless steel plate) having a thickness of about 1 to 3 mm into a hat-shaped cross section.

[0028] Moreover, the cross beams 3, 4 which are laser welded to the side outer plate 1 are joined to the vertical beams 6. Therefore, the side outer plate 1 is not easily affected by thermal distortion and the like when the vertical beams 6 and the cross beams 5 are joined, and the aesthetic appearance of the side outer plate 1 can be maintained. Here, the cross beams 5 are welded (for example, laser welded RY in the vertical direction of the vehicle) to the top plate portions 32, 42 of all the cross beams 3, 4. Moreover, the flange portions 61 of the vertical beams 6 are intermittently joined (for example, spot welded SY) to the cross beams 5 from their upper end portions 51 to their lower end portions 52 at predetermined intervals.

[0029] 6 shows the EE cross section shown in FIG. 2. FIG. 7 shows an enlarged cross section of the F portion shown in FIG. 3. As shown in FIG. 6, the glass plate 2G of the continuous window 2 is divided along the vertical direction of the vehicle within the range of the continuous window 2 of the winding plate 5, and the joints 2GT of the divided glass plates 2G1, 2G2 are connected to the winding plate 5 via a seal member 7. Therefore, the glass plates 2G1, 2G2 of the continuous window 2 are supported from the inside of the vehicle by the winding plate 5 reinforced by the vertical frame 6. Therefore, the outer surfaces of the glass plates 2G1, 2G2 of the continuous window 2 can be formed to be approximately flush with each other with the seal member 7 that fills the gap of the minute joint 2GT sandwiched therebetween. And the glass plate 2G is not largely divided by the side outer plate 1. As a result, the continuous window 2 formed continuously in the vehicle longitudinal direction can improve the aesthetics and design of the vehicle exterior.

[0030] Here, the glass panes 2G (2G1, 2G2) are divided at both ends 53, 54 in the vehicle longitudinal direction within the continuous window 2 of the joint plate 5, and the vertical frames 6 are joined to both ends 53, 54 of the joint plate 5, so that the joints 2GT of the divided glass panes 2G1, 2G2 can be connected via the seal members 7 to both ends 53, 54 of the joint plate 5, which is firmly reinforced by the vertical frames 6. Therefore, the divided glass panes 2G1, 2G2 can be connected to the joint plate 5 more stably, and a continuous window 2 that is longer in the vehicle longitudinal direction and has excellent aesthetics can be formed.

[0031] Also, the glass plate 2G can be divided into a glass plate 2G1 for windscreen facing the windscreen plate 5 and a glass plate 2G2 for observation through which the scenery outside the train can be seen from the passenger compartment, and the area of ​​the glass plate 2G1 for windscreen can be made smaller than the area of ​​the glass plate 2G2 for observation. This makes it possible to reduce the weight of the entire glass plate 2G by making the thickness of the glass plate 2G1 thinner than that of the glass plate 2G2 for observation, which is also advantageous in terms of cost. As a result, it is possible to form a continuous window 2 that is longer in the longitudinal direction of the train and has excellent aesthetics, while promoting weight reduction and cost reduction of the train.

[0032] The glass plate 2G1 shielded by the soffit plate 5 may be made of opaque glass HG or light-shielding glass SG. In this case, the soffit plate 5 is not visible from the outside of the vehicle, and the aesthetics and design of the soffit portion 2H supporting the glass plate 2G of the continuous window 2 can be improved. For the opaque glass HG, for example, frosted glass, shading glass, colored glass, etc. can be used. For the light-shielding glass SG, for example, laminated glass sandwiching a black intermediate film 2G11, mirror glass with a reflective film formed on the back surface, etc. can be used. For the observation glass plate 2G2, for example, double-glazed glass HSG having a hollow portion 2G21 between the glass plates can be used. This allows the heat insulation and soundproofing to be improved while maintaining the transparency.

[0033] Moreover, Fig. 8 shows a partial side view of a part of the continuous window shown in Fig. 1 as seen from outside the vehicle (the vehicle exterior side). Fig. 9 shows a side view of the observation glass plate of the continuous window shown in Fig. 8. As shown in Figs. 8 and 9, it is advisable to form a light-shielding layer (e.g., a black ceramic layer) 2G22 on the outer peripheral edge of the observation glass plate 2G2. The light-shielding layer (e.g., a black ceramic layer) 2G22 can hide the ends of the interior material (not shown) that covers the siding panel 5, vertical ribs 6, horizontal ribs 3, 4, etc., and can improve the aesthetic appearance of the outer peripheral edge of the continuous window 2.

[0034] Therefore, according to this railway vehicle 10, laser welding of the side outer plate 1 made of stainless steel plate SK can be easily performed, and the aesthetics and design of the winding portion 2H supporting the glass plate 2G of the continuous window 2 formed in the side outer plate 1 can be improved.

[0035] As shown in Fig. 2 and Fig. 6, the vertical bones 6 are arranged symmetrically with respect to the center line CL of the headboard 2H, and are joined to both ends 53, 54 of the headboard 5. The headboard 5 is composed of an upper headboard 5J joined to the horizontal bone 3 above the window, a lower headboard 5K joined to the horizontal bone 4 below the window, and a connecting headboard 5T that connects the upper headboard 5J and the lower headboard 5K inside the continuous window 2. The pair of vertical bones 6 are joined to both ends 53, 54 of the connecting headboard 5T. The upper headboard 5J and the lower headboard 5K are formed wider than the connecting headboard 5T, and the corners SM where the upper headboard 5J and the lower headboard 5K intersect with the connecting headboard 5T are formed in an arc shape. This alleviates stress concentration at the upper and lower corners SM, and enables the curtain portion 1a and waist portion 1b of the side panel 1 to be reinforced more effectively on the passenger compartment side of the continuous window 2.

[0036] In addition, in the present railway vehicle 10, as shown in Fig. 6, the seal member 7 preferably includes a pair of sponge-like first synthetic rubber plates 71, 72 connected to the periphery of the joint 2GT between the glass plates 2G1, 2G2, a sealant 73 filled in the gap at the joint 2GT and the gap between the first synthetic rubber plates 71, 72, and a second synthetic rubber plate 74 connecting the first synthetic rubber plates 71, 72 and the sealant 73 to the wind-mounted plate 5. Here, the first synthetic rubber plates 71, 72 and the second synthetic rubber plate 74 may be made of synthetic rubber (e.g., CR rubber (chloroprene rubber)) having excellent mechanical strength, weather resistance, heat resistance, cold resistance, oil resistance, etc. The sealant 73 may be made of a sealant having excellent weather resistance, water resistance, heat resistance, etc., such as a silicone-based sealant.

[0037] With the above configuration, the sealant 73 filled in the gap at the joint 2GT of the glass plates 2G1, 2G2 is enclosed by the first synthetic rubber plates 71, 72 and the second synthetic rubber plate 74. Therefore, even if there is a difference in plate thickness between the front glass plate 2G1 facing the front plate 5 and the observation glass plate 2G2 through which the view outside the vehicle can be seen from the passenger compartment, the difference in plate thickness can be absorbed, while reducing the step on the outer surface of the vehicle between the front glass plate 2G1 and the observation glass plate 2G2, thereby further improving the aesthetics of the continuous window 2.

[0038] Moreover, the glass plates 2G1, 2G2 can be brought closer to the side outer plate 1 while maintaining the separation distance t2 between the windscreen plate 5 and the glass plate 2G1. As a result, the step t1 between the glass plates 2G1, 2G2 and the side outer plate 1 can be reduced, and the aesthetics of the side outer plate 1 in which the continuous window 2 is formed can be further improved. The first synthetic rubber plates 71, 72 are formed in a sponge-like shape, and can flex flexibly according to the difference in thickness of the glass plates 2G1, 2G2. The sponge-like first synthetic rubber plates 71, 72 can also connect the glass plates 2G1, 2G2 and the windscreen plate 5 while absorbing vibrations of the vehicle.

[0039] In addition, in the present railway vehicle 10, as shown in Figs. 3 and 7, the upper end 2GJ and the lower end 2GK of the glass plate 2G (2G1, 2G2) are preferably bonded by being pressed to the cross beams 3, 4 (in this embodiment, the window side surface 331 of the vertical flange portion 33 on the window upper end 21 side of the cross beam 3 and the window side surface 431 of the vertical flange portion 43 on the window lower end 22 side of the cross beam 4) joined to the window upper end 21 and the window lower end 22 of the continuous window 2 while being fitted into the sealing elastic member 81 by the glass retainer 9 extending in the vehicle longitudinal direction. Here, for example, foamed urethane rubber or the like can be used for the sealing elastic member 81. For example, an extruded member made of aluminum or an aluminum alloy can be used for the glass retainer 9. The glass retainer 9 is fastened to the cross beams 3, 4 by, for example, a screw or the like. Further, a sealant 82 that seals the outer edge side of the sealing elastic member 81 is filled in the gaps between the window upper end 21 and the window lower end 22 and the glass plate 2G (2G1, 2G2).

[0040] With the above-mentioned configuration, the divided glass plates 2G1, 2G2 can be pressed and bonded continuously to the cross frames 3, 4 by the common glass holder 9 extending in the longitudinal direction of the vehicle. This reduces the variation in the step t1 between the glass plates 2G1, 2G2 and the side outer panel 1, and further improves the aesthetics of the side outer panel 1 in which the continuous window 2 is formed.

[0041] <Modification> Needless to say, the present railway vehicle 10 can be modified in various ways without departing from the gist of the present invention. For example, in the present railway vehicle 10, as shown in Figs. 6 and 8, the glass plate 2G (2G1, 2G2) is divided at both ends 53, 54 in the longitudinal direction of the vehicle within the continuous window 2 of the wind-mounted panel 5. However, the position of division of the glass plate 2G is not limited to this. For example, as in a modified railway vehicle 10B shown in Figs. 10 to 12, the glass plate 2GB (2G2B, 2G2B) may be divided at a center CL in the longitudinal direction of the vehicle within the continuous window 2B of the wind-mounted panel 5. In this case, the glass plate 2GB of the continuous window 2B can be used in common with the observation glass plate 2G2B, which can reduce costs. It is preferable to form a light-shielding layer (e.g., a black ceramic layer) 2G22B on the outer periphery of the observation glass plate 2G2B widely in the longitudinal direction of the vehicle so as to hide the entire wind-mounted panel 5.

[0042] In addition, in the present railway vehicle 10, the vertical bones 6 are joined to both ends 53, 54 of the windscreen plate 5, and a pair of vertical bones 6, 6 spaced apart in the vehicle longitudinal direction are arranged parallel to the vehicle up-down direction. However, it is not necessary to be limited to a pair of vertical bones 6, 6. For example, a single vertical bone 6 may be used. In this case, left and right flange portions 61 are joined to both ends 53, 54 of the windscreen plate 5.

[0043] <Action and effect> According to the railway cars 10 and 10B according to the present embodiment described above in detail, the side outer plate 1 is laser welded from the inner side of the car along the longitudinal direction of the car to the cross beams 3 and 4 arranged on the inner side of the car from the side outer plate 1, so that the weld bead (back bead) does not appear on the outer surface of the side outer plate 1, and the strength of the side outer plate 1 in the longitudinal direction of the car can be increased while improving the aesthetic appearance of the car. The cross beam 3 located above the continuous window 2 and 2B is located near the window upper end 21 of the continuous window 2 and 2B and the upper end 11 of the side outer plate 1 (curtain portion 1a), and is arranged in parallel between the two and spaced apart vertically. The cross beam 4 located below the continuous window 2 and 2B is located near the window lower end 22 of the continuous window 2 and 2B and the lower end 12 of the side outer plate 1 (waist portion 1b), and is arranged in parallel between the two and spaced apart vertically. Therefore, the cross beams 3 and 4 can be accurately overlapped with the curtain portion 1a and waist portion 1b of the side outer plate 1. Furthermore, a predetermined space is formed between adjacent cross beams 3 above the windows and between adjacent cross beams 4 below the windows, allowing the laser beam RB to move linearly in the longitudinal direction of the vehicle. Therefore, the cross beams 3, 4 can be stably set with no gaps against the curtain portion 1a and waist portion 1b of the side panel 1, allowing high-quality laser welding to be performed.

[0044] In addition, the cross beams 3, 4 are joined to the cross beams 5 arranged on the inside of the vehicle from the cross beams 3, 4 at the joint portion 2H of the continuous window 2, 2B, and extend in the vertical direction of the vehicle from the top cross beam 3c to the bottom cross beam 4e. The cross beams 5 are joined to the vertical beams 6 arranged on the inside of the vehicle from the cross beams 5 to the top end 51 to the bottom end 52 of the cross beams 5. Therefore, all the cross beams 3 located above the continuous window 2, 2B and all the cross beams 4 located below the continuous window 2, 2B can be connected on the inside of the vehicle by the cross beams 5 and the vertical beams 6 at the intermediate portion of the vehicle longitudinal direction of the continuous window 2, 2B. This allows the side outer plate 1 forming the horizontally long continuous window 2, 2B to be reinforced from the inside of the vehicle with a simple structure. The cross beams 5 joined to the vertical beams 6 are joined to the cross beams 3, 4 laser-welded to the side outer plate 1. Therefore, the side skin 1 is less susceptible to the effects of thermal distortion and the like that occurs when the vertical beams 6 and the pierced panel 5 are joined, and the aesthetic appearance of the side skin 1 can be maintained.

[0045] In addition, the glass plates 2G, 2GB of the continuous window 2, 2B are divided along the vertical direction of the vehicle within the range of the continuous window 2, 2B of the winding plate 5, and the joints 2GT of each divided glass plate 2G, 2GB are connected to the winding plate 5 via the sealing member 7, so that each glass plate 2G (2G1, 2G2), 2GB (2G2B) of the continuous window 2, 2B is supported from the inside of the vehicle by the winding plate 5 reinforced by the vertical frame 6. Therefore, the outer surfaces of each glass plate 2G (2G1, 2G2), 2GB (2G2B) of the continuous window 2, 2B can be formed to be approximately flush with each other with the sealing member 7 that fills the gap of the minute joint 2GT sandwiched therebetween. And the glass plates 2G, 2GB are not largely divided by the side outer plate 1. As a result, the continuous window 2, 2B formed continuously in the vehicle longitudinal direction can improve the aesthetics and design of the vehicle exterior.

[0046] Therefore, according to this embodiment, it is possible to provide railway cars 10, 10B that can easily perform laser welding of the side outer panel 1 made of stainless steel plate SK, while also improving the aesthetics and design of the winding portion 2H that supports the glass plates 2G, 2GB of the continuous windows 2, 2B formed in the side outer panel 1.

[0047] According to this embodiment, the glass plate 2G is divided at both ends 53, 54 of the continuous window 2 in the longitudinal direction of the vehicle by the ridge plate 5, and the vertical frame 6 is joined to both ends 53, 54 of the ridge plate 5, so that the joints 2GT of the divided glass plates 2G1, 2G2 can be connected to both ends 53, 54 of the ridge plate 5, which is strongly reinforced by the vertical frame 6, via the seal member 7. Therefore, the divided glass plates 2G1, 2G2 can be connected to the ridge plate 5 more stably, and a continuous window 2 that is longer in the longitudinal direction of the vehicle and has excellent aesthetics can be formed. Also, the glass plate 2G can be divided into a ridge glass plate 2G1 facing the ridge plate 5 and a view glass plate 2G2 through which the view outside the vehicle can be seen from the passenger compartment, so that the area of ​​the ridge glass plate 2G1 can be made smaller than the area of ​​the view glass plate 2G2. This allows the thickness of the glass plate 2G1 for the viewing area to be thinner than that of the glass plate 2G2 for the observation area, making the glass plate 2G lighter overall and advantageous in terms of cost. As a result, it is possible to form a continuous window 2 that is longer in the longitudinal direction of the vehicle and has excellent aesthetic appearance, while promoting weight reduction and cost reduction of the vehicle.

[0048] Furthermore, according to this embodiment, the sealing member 7 includes a pair of sponge-like first synthetic rubber plates 71, 72 connected to the peripheral portion of the joint 2GT between the glass plates 2G1, 2G2, a sealant 73 filled in the gap at the joint 2GT and the gap between the first synthetic rubber plates 71, 72, and a second synthetic rubber plate 74 connecting the first synthetic rubber plates 71, 72 and the sealant 73 to the windscreen plate 5. Therefore, even if there is a difference in plate thickness between the windscreen glass plate 2G1 facing the windscreen plate 5 and the observation glass plate 2G2 through which the view outside the vehicle can be seen from the passenger compartment, the difference in plate thickness can be absorbed, and the step on the outer surface of the vehicle between the windscreen glass plate 2G1 and the observation glass plate 2G2 can be reduced, thereby further improving the aesthetics of the continuous window 2.

[0049] According to this embodiment, the upper end 2GJ and the lower end 2GK of the glass plates 2G (2G1, 2G2), 2GB (2G2B) are pressed and bonded to the cross frames 3, 4 joined to the window upper end 21 and the window lower end 22 of the continuous window 2, 2B by the glass holder 9 extending in the vehicle longitudinal direction while being fitted into the sealing elastic member 81, so that the divided glass plates 2G1, 2G2 can be pressed and bonded continuously to the cross frames 3, 4 by the common glass holder 9 extending in the vehicle longitudinal direction. Therefore, the variation in the step t1 between the glass plates 2G (2G1, 2G2), 2GB (2G2B) and the side outer panel 1 can be reduced, and the aesthetics of the side outer panel 1 forming the continuous window 2, 2B can be further improved.
