In order to achieve this object, the railway vehicle of the present invention comprises a window block having an outer panel with a window opening formed thereon, and an entrance block having an entrance frame with an entrance opening formed thereon. The entrance block is joined to form a side structure, and includes a shear plate that is joined to the inner side surface of the outer plate of the window block, and a cover member that is arranged on the entrance block. In a state in which an edge portion of the outer plate on the vehicle longitudinal direction side protrudes toward the entrance opening portion more than an edge portion of the entrance frame on the vehicle longitudinal direction side, the entrance frame is positioned on a surface of the outer plate on the vehicle inner side. The shear plate is joined to a curtain plate portion which is a portion of the entrance frame positioned above the entrance opening, and the cover member is disposed on the vehicle outer side of the curtain plate portion of the entrance block. be done .
Further, the railway vehicle of the present invention includes a window block having an outer panel with a window opening formed thereon, and an entrance block having an entrance frame with an entrance opening formed thereon, wherein the window block and the entrance block are It is joined to form a side structure, and includes a shear plate that is joined to a vehicle-interior surface of the outer plate of the window block, and an edge of the outer plate on the vehicle longitudinal direction side of the entrance frame. The entrance frame is joined to the surface of the outer plate on the inside of the vehicle in a state where the edge portion on the vehicle longitudinal direction side protrudes toward the entrance opening, and the entrance block is provided on one side in the vehicle longitudinal direction and on the other side in the vehicle longitudinal direction. The window blocks are joined to each other, and the shear plate is joined to a curtain plate portion that is a portion of the entrance frame located above the entrance opening, and the shear plate of the window block on one side in the vehicle longitudinal direction and the shear plate of the window block on the other side in the longitudinal direction of the vehicle, a gap of 2/1000 or more and 10/1000 or less of the interval between the window blocks facing each other in the longitudinal direction of the vehicle is formed.

According to the railway vehicle of claim 1 or 2 , in a state in which the edge of the outer plate on the vehicle longitudinal direction side protrudes toward the entrance opening than the edge of the entrance frame on the vehicle longitudinal direction side, Since the entrance frame is joined to the inner surface, it is possible to suppress the formation of a step on the vehicle outer side of the side structure.

The shear plate is joined to the inner surface of the outer plate of the window block. A load acting on the block) can be transferred to the entrance block (window block) via the shear plate.

According to the railcar of claim 1 , since the cover member is provided on the vehicle outer side of the curtain plate portion of the entrance block, the shear plate and the curtain plate portion can be covered, and the appearance can be improved. Further, by setting the plate thickness of the cover member to be the same as the plate thickness of the outer plate, it is possible to avoid forming a step on the outside of the vehicle of the side structure.

According to the railroad vehicle of claim 2 , between the shear plate of the window block on one side in the longitudinal direction of the vehicle and the shear plate of the window block on the other side in the longitudinal direction of the vehicle, there is a gap between the window blocks facing each other in the longitudinal direction of the vehicle. Since a gap of 2/1000 or more is formed, assuming that the side structure will sag due to deflection due to its own weight, when joining the window block in an inclined (cambered) posture with respect to the entrance block, the shear plate Interference between them can be suppressed.

On the other hand, the gap between the shear plate of the window block on one side in the longitudinal direction of the vehicle and the shear plate of the window block on the other side in the longitudinal direction is 10/1000 or less of the gap between the window blocks facing each other in the longitudinal direction of the vehicle. The length of the shear plate for supporting the cover member from the inside of the vehicle can be ensured. Therefore, it is possible to suppress bending of a part of the cover member due to an external force such as running wind.

According to the railway vehicle of claim 3 , in addition to the effects of the railway vehicle of claim 1 or 2 , the shear plate has an edge on the side facing the entrance opening in the longitudinal direction of the vehicle and the entrance in the vertical direction of the vehicle. Since the edge connecting the edge facing the opening is curved in an arc shape, stress concentration on the shear plate is suppressed when the load is transmitted between the window block and the entrance block. As a result, breakage of the shear plate can be suppressed.

Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. First, referring to FIG. 1, the configuration of the railcar 10 will be described. FIG. 1 is a perspective view of a railway vehicle 10 according to one embodiment of the invention. Note that arrows FB, UD, and LR in FIG. 2 to 4 , and the same applies to FIGS. 2 to 4 .

As shown in FIG. 1, a railcar 10 is composed of a side structure 11, a roof structure 12, an end structure 13, and an underframe (not shown). The side structure 11 has a plurality of (two in this embodiment) window blocks 20 arranged along the front-rear direction (arrow FB direction), and a plurality of window blocks 20 at both ends of the side structure 11. A pair of car end blocks 30 arranged in a sandwiching manner and a plurality of (three in this embodiment) arranged between a plurality of window blocks 20 and between the window block 20 and the car end block 30 ) and an inlet upper cover 50 . It should be noted that illustration of a door arranged in the entrance block 40 is omitted.

Next, the configuration of the side structure 11 will be described with reference to FIGS. 2 and 3. FIG. FIG. 2 is a partially enlarged view of the side structure 11 as seen from the inside of the vehicle (the arrow R direction side). 3A is a partial enlarged view of the window block 20 viewed from the inside of the vehicle, and FIG. 3B is a partially enlarged view of the entrance block 40 viewed from the outside of the vehicle (arrow L direction side). 2 and 3, the side structure 11 (the window block 20 and the entrance block 40) arranged on the left side (arrow L direction side) is illustrated.

As shown in FIGS. 2 and 3, the window block 20 is welded to an outer plate 21 extending in the front-rear direction (arrow FB direction) and a surface of the outer plate 21 on the inside of the vehicle (arrow R direction). a first shear plate 22 and a second shear plate 23, and a rib member 24 that is welded to the inner surface of the outer plate 21, the first shear plate 22, or the second shear plate 23. configured for

The outer plate 21, the first shear plate 22, and the second shear plate 23 are each formed from a metal plate material. Window openings 25a and 25b (see FIG. 1) are formed in the outer plate 21 in the plate thickness direction (direction of arrows LR).

The first shear plate 22 is a member for securing the strength of the outer plate 21, and is arranged to surround the window openings 25a and 25b (see FIG. 1). Edge portions 22a along the vertical direction (arrow UD direction) formed at both ends of the first shear plate 22 in the front-rear direction (arrow FB direction) are formed at both ends of the outer plate 21 in the front-rear direction. The window block 20 is formed closer to the front-rear center side of the window block 20 (on the window opening 25b side) than the edge portion 21a along the vertical direction. As a result, the first shear plate 22 is not arranged around the edge 21a of the outer plate 21 .

Projections 22b are formed on the first shear plate 22 from the edge 22a toward the edge 21a of the outer plate 21, and are formed at both ends of the projection 22b in the front-rear direction (arrow FB direction). A protruding edge 22c extending in the vertical direction (arrow UD direction) is formed at a position substantially identical to the edge 21a of the outer plate 21. As shown in FIG.

For example, when the outer plate 21 is formed by abutting two plate materials in a posture along the vertical direction (the direction of the arrows UD), the projecting portion 22b straddles the butted ends of the two plate materials, By forming the protruding edge 22c at a position that is substantially the same as the edge 21a of the outer plate 21, the protruding portion 22b and the outer plate 21 can be joined up to the edge 21a of the outer plate 21 (two plate materials). As a result, the bonding strength can be improved.

In addition, the periphery of one end of the two plate materials is cut off, and the outer plate 21 is formed by joining the surface of one of the plate materials on the vehicle exterior side to the surface of the other plate material on the vehicle interior side. In this case, the projecting portion 22b may not be formed.

The second shear plate 23 is a member for transmitting load between the entrance block 40 and the window block 20 . Also, the second shear plate 23 is a member for supporting the inlet upper cover 50 . The second shear plate 23 includes a base portion 23a that is joined to the upper portion of the outer plate 21 (a portion on the side of the arrow U), and a front-to-rear direction (arrow F −B direction).

The lower portion of the base portion 23a (the portion on the arrow D direction side) is joined to the upper portion of the first shear plate 22 (the portion on the arrow U direction side) by welding. Thereby, the second shear plate 23 is supported by the outer plate 21 and the first shear plate 22 . As a result, the load generated in the second shear plate 23 can be transmitted to the outer plate 21 and the first shear plate 22, compared to the case where the second shear plate 23 is supported only by the outer plate 21. Damage to the outer plate 21 can be easily suppressed.

The support portion 23b is formed in a substantially rectangular shape elongated in the front-rear direction (arrow FB direction). A plurality of (in this embodiment, two) lightening holes 23c are formed in the front-rear direction in the support portion 23b. The weight of the second shear plate 23 is reduced by the lightening holes 23c.

The second shear plate 23 is positioned above (in the direction of the arrow U) the lower edge (in the direction of the arrow D) of the base portion 23a. An edge on the side facing the entrance opening 44) is formed, and an edge along the vertical direction (the direction of arrows UD) is formed between the lower edges of the base portion 23a and the support portion 23b. , the edge on the side facing the inlet opening 44 described later) is formed. At the edge connecting the edge along the vertical direction and the edge on the lower side of the support portion 23b, a curved portion 23d that is concave upward is curved in an arc shape to suppress stress concentration. It is formed.

The curvature of the curved portion 23d is formed to be smaller than the curvature of the upper frame curved portion 42a of the entrance block 40, which will be described later.

A block opening 26 is formed by the edge 21a of the pair of window blocks 20 (outer plate 21) and the edge on the lower side (arrow D direction side) of the second shear plate 23 (supporting portion 23b).

Here, the short sides 23e, which are the edges formed at the protruding distal end portions of the pair of second shear plates 23 (supporting portions 23b), are abutted against each other and separated by a predetermined distance (in this embodiment, , 8 mm). That is, a gap is formed between the pair of second shear plates 23 in the front-rear direction (arrow FB direction). In the present embodiment, the distance between the facing edge portions 21a of the pair of outer plates 21 in the front-rear direction is set to 1370 mm, and the gap between the pair of second shear plates 23 (support portions 23b) is set to 1370 mm. It is set to approximately 6/1000 of the distance between the edges 21a of the outer plate 21 facing each other.

By forming a gap between the pair of second shear plates 23 in this way, the window block 20 is tilted (camber ), interference between the second shear plates 23 can be suppressed.

Here, if the gap formed between the pair of second shear plates 23 is small, the second shear plates 23 may interfere with each other when joining in a cambered posture. In order to suppress interference between the second shear plates 23, the gap between the pair of second shear plates 23 (supporting portions 23b) is set to 2/2 of the distance between the edges 21a of the pair of outer plates 21 facing each other. It is desirable to be formed larger than 1000.

The rib member 24 is a member for ensuring the strength of the side structure 11, and can be attached to the outer plate 21, the first shear plate 22 or the second shear plate 23 in a posture along the front-rear direction (arrow FB direction). and a plurality of lateral rib members 24a welded to the inner surface of the vehicle (arrow R direction side), and welded to the inner surface of the lateral rib member 24a in the vertical direction (arrow UD direction). It mainly comprises a plurality of longitudinal rib members 24b that are joined together by the . Each member of these rib members 24 is formed in a hat shape from a metal plate. The vehicle-interior surface of the rib member 24 is defined as the surface of the rib member 24 that is formed on the vehicle-interior side.

Note that the plurality of transverse rib members 24a are the same except for their length in the front-rear direction (arrow FB direction), and are therefore described with the same reference numerals. Similarly, the plurality of longitudinal rib members 24b are the same except for their length in the vertical direction (the direction of arrows UD), and therefore are denoted by the same reference numerals. Further, although the vehicle end block 30 differs from the window block 20 in length in the front-rear direction, it is otherwise configured in the same manner as the window block 20, so that description thereof will be omitted.

The edge of the transverse rib member 24a on the side of the block opening 26 (the side of the edge 21a of the outer plate 21) is spaced apart from the edge 21a of the outer plate 21 by a predetermined distance (128 mm in this embodiment). be.

The entrance block 40 includes a pair of vertical frame members 41 arranged in a vertical direction (arrow UD direction) with a predetermined interval in the front-rear direction (arrow FB direction), and a pair of A rectangular shape mainly comprising an upper frame member 42 bridged over the vertical frame members 41 and a lower frame member 43 bridged under the pair of vertical frame members 41, and having an outer edge larger than the block opening 26. It is formed in a frame shape.

The vertical frame member 41 includes a joint member 41a that is welded to the surface of the frame member 24 (transverse frame member 24a) of the window block 20 on the vehicle interior side (arrow R direction side), and a pair of joint members 41a that face each other. and a connecting plate 41c that is welded to the surfaces of the joining member 41a and the entrance hook 41b on the outside of the vehicle (in the direction of the arrow L).

The joining member 41a is a member for joining the window block 20 and the entrance block 40 together. The entrance hook 41b is a member for preventing the space formed between the outer plate 21 and the side sliding door (not shown) from being visually recognized.

The connecting plate 41c is a member for connecting (joining) the joining member 41a and the inlet hook 41b. The joining member 41a and the inlet hook 41b are arranged side by side in the front-rear direction (arrow FB direction), and the joining member 41a and the inlet hook 41b are connected via the connecting plate 41c, so that the left-right direction (arrow L- The thickness of the inlet block 40 in the R direction) is formed small.

A pair of connecting plates 41c are arranged with a predetermined distance therebetween along the vertical direction (direction of arrows UD). It is formed slightly larger than the vertical length of 22b. Thereby, the projecting portion 22b can be arranged between the pair of connecting plates 41c facing each other.

The connecting plate 41 c is made of a metal plate material, and the thickness of the connecting plate 41 c (thickness in the vehicle width direction) is substantially the same as the thickness of the first shear plate 22 . As a result, in a state in which the connecting plate 41c is joined to the surface of the outer plate 21 on the vehicle interior side (arrow R direction side), the vehicle interior surface of the projecting portion 22b of the first shear plate 22 is connected to the joint member 41a and the inlet port. It becomes possible to abut on the surface of the hook 41b on the outside of the vehicle (in the direction of the arrow L). As a result, the first shear plate 22, the joining member 41a, and the inlet hook 41b can be joined. That is, in addition to joint spot welding between the outer plate 21 and the connecting plate 41c, joint spot welding is performed between the first shear plate 22 (projecting portion 22b), the joint member 41a, and the entrance hook 41b, so that the window block 20 and the entrance The joint spot welding interval of the block 40 can be narrowed, and the joint strength can be increased.

The upper frame member 42 is a member for joining the entrance block 40 to the second shear plate 23 of the window block 20 . At the lower (arrow D direction side) edges on both sides (the connecting portion side with the vertical frame member 41) of the upper frame member 42 in the front-rear direction (arrow FB direction), upward (arrow U direction) A concave upper frame curved portion 42a is formed to curve in an arc shape.

Next, with reference to FIG. 4, joining of the window block 20 and the entrance block 40 will be described. 4(a) is a partially cut end view of the side structure 11 taken along the IVa-IVa line in FIG. 2, and FIG. 4(b) is a partially cut end view of the side structure 11 taken along the IVb-IVb line in FIG. 4(c) is a cut end view of the side structure 11 taken along line IVc-IVc of FIG.

As shown in FIGS. 4(a) and 4(b), the window block 20 and the vertical frame member 41 of the entrance block 40 are joined together by connecting the edge 21a of the outer plate 21 to the vertical frame member 41 (connection plate 41c). The connecting plate 41c is welded to the surface of the window block 20 (outer plate 21) on the inside of the vehicle (in the direction of the arrow R) while protruding from the edge 41d.

As a result, it is possible to suppress the occurrence of a step on the outside of the side structure 11 (the side in the direction of arrow L), thereby improving the appearance of the railcar 10 .

In addition, the connecting plate 41c is welded to the vehicle interior (arrow R direction) surface around the edge 21a of the outer plate 21, and the joint member 41a is welded to the vehicle interior surface of the lateral rib member 24a. be. Since the rib member 24 is arranged at a predetermined distance from the edge portion 21a of the outer plate 21, the rib member 24 is provided at a plurality of locations (in the present embodiment, at two locations) at a predetermined distance in the front-rear direction (arrow FB direction). By joining the window block 20 and the entrance block 40 at the point), the joint strength between the window block 20 and the entrance block 40 can be improved.

Furthermore, by joining the inlet block 40 around the edge 21 a of the outer plate 21 , the strength around the edge 21 a of the outer plate 21 can be secured by the inlet block 40 . This eliminates the need to join the first shear plate 22 and the rib member 24 around the edge 21a of the outer plate 21, and the weight of the side structure 11 can be reduced.

In addition, by joining the entrance block 40 to the surface of the outer plate 21 on the vehicle inner side (arrow R direction side), the outer plate 21 can cover the vehicle outer surface (arrow L direction side) of the entrance block 40. can. As a result, the surface of the entrance block 40 on the outside of the vehicle does not need to be finished for the purpose of improving the appearance, and the manufacturing cost can be reduced.

On the other hand, the surface of the entrance block 40 on the vehicle interior side (arrow R direction side) is covered with the interior panel (not shown) disposed on the vehicle interior side of the side structure 11, so finishing processing is not required, and the manufacturing cost is reduced. can be suppressed from increasing.

The window block 20 and the upper frame member 42 of the entrance block 40 are joined to each other, as shown in FIG. This is done by contacting and welding the frame member 42 . In addition, the inlet upper cover 50 is welded to the surface of the second shear plate 23 on the outside of the vehicle (in the direction of the arrow L). By joining the inlet upper cover 50 to the vehicle-exterior surface of the second shear plate 23, it is possible to prevent the second shear plate 23 and the upper frame member 42 from being seen from the vehicle exterior.

In addition, the plate thickness of the inlet upper cover 50 is formed to be substantially the same as the plate thickness of the outer plate 21, so that the side structure 11 (the outer plate 21 and the inlet upper cover 50) is located outside the vehicle (arrow L direction side). The surface can be formed substantially flush. As a result, formation of a step in the side structure 11 (between the outer plate 21 and the inlet upper cover 50) can be avoided. By these, the appearance of the railcar 10 can be improved.

Further, the support portions 23b of the pair of second shear plates 23 are abutted in the front-rear direction (arrow FB direction), thereby supporting the entrance upper cover 50 from the inside of the vehicle (arrow R direction side) (entrance upper portion The length of the second shear plate 23 is ensured for restricting the deformation of the cover 50 toward the inside of the vehicle. As a result, it is possible to prevent a portion of the inlet upper cover 50 from being bent (deformed toward the inside of the vehicle) due to an external force such as running wind.

In addition, in order to secure the length of the second shear plate 23 for supporting the inlet upper cover 50 from the inside of the vehicle (direction of arrow R), a pair of second shear plates 23 in the front-rear direction (direction of arrow FB) is required. The gap between the shear plates 23 (supporting portions 23b) is desirably formed to be smaller than 10/1000 of the distance between the edge portions 21a of the pair of outer plates 21 facing each other.

Here, the second shear plate 23 and the upper frame member 42 are joined above the entrance opening 44 (between the edges 21a of the pair of window blocks 20) to form the entrance block 40 (window block 20). can be transmitted to the window block 20 (entrance block 40 ) via the second shear plate 23 . Thereby, the load can be supported by the entrance block 40 and the window block 20, and the load acting on the entrance block 40 (window block 20) can be reduced.

As a result, the curvature of the upper frame curved portion 42a of the upper frame member 42 can be increased and the entrance opening 44 can be made larger than when the load acting on the entrance block 40 is supported by the entrance block 40 alone.

As described above, since the second shear plate 23 is formed with the curved portion 23 d, the second shear plate 23 (curved portion) is formed when the load is transmitted between the entrance block 40 and the window block 20 . It is possible to suppress the occurrence of stress concentration in the portion 23d), and it is possible to suppress the breakage of the second shear plate 23 (the curved portion 23d).

Further, since the second shear plate 23 is joined to the outer plate 21, the curved portion 23d can be formed at a position away from the entrance opening 44 in the front-rear direction (arrow FB direction). As a result, the curved portion 23d can be arranged on the opposite side (the window block 20 side) of the entrance opening 44 from the upper frame curved portion 42a in the front-rear direction, and the entrance opening 44 can be made smaller by the curved portion 23d. can be suppressed.

In addition, the curvature of the curved portion 23d can be made smaller than the curvature of the upper frame curved portion 42a by forming the curved portion 23d at a position away from the entrance opening 44 in the front-rear direction (arrow FB direction). Thereby, when a load is transmitted between the entrance block 40 and the window block 20, it is possible to suppress the occurrence of stress concentration on the second shear plate 23 (the curved portion 23d).
