Description

[Technical Field]

[0001] The present invention relates to a railway vehicle body structure and a base plate for a drive unit. [Background technology]

[0002] Railway vehicles such as express trains and commuter trains have side doors on their side structures for passengers to enter and exit. The side doors are suspended from rails and are opened and closed in the direction of the track by a drive unit fixed to the side structure above the side doors.

[0003] Known examples of drive devices include the opening and closing device disclosed in Patent Document 1, but drive devices are selected from a variety of drive devices with different manufacturers and drive systems and are used as appropriate. Known drive systems include, for example, electric types using a motor as the drive source and pneumatic types using an air cylinder as the drive source. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-309849 Summary of the Invention [Problem to be solved by the invention]

[0005] The drive unit is generally fixed to the frame members (horizontal and vertical frames) that make up the side structure. This allows the frame members to support the mass of the drive unit and absorb the reaction force that the drive unit receives when operating the door. However, because the shape of the drive unit varies depending on the drive system and manufacturer, the shape of the frame members and their placement position must be designed each time to suit the selected drive unit. This can lead to a decrease in the manufacturing efficiency of railway vehicles.

[0006] The present invention is intended to solve the above problems, and aims to provide a body structure and a base plate for a drive unit that enable the design of railway vehicle bodies to be standardized regardless of the type of drive unit. [Means for solving the problem]

[0007] In order to solve the above problems, the body structure of the present invention has the following configuration.

[0008] (1) A railway vehicle structure comprising a side structure, an opening for a side door provided in the side structure, and a frame member reinforcing the side structure above the opening, and a drive unit for opening and closing the side door is fixed to the frame member, the drive unit being fixed to the frame member via a drive unit base plate connected to the frame member, and , railway vehicles A pair of vertical bones extending along the vertical direction of the vehicle body are provided, and the vertical bones are Opening The vertical ribs are provided with a lower portion below the upper end portion and an upper portion above the upper end portion, and the upper portion has a thickness in the sleeper direction that is thinner than that of the lower portion. of the vehicle body The base plate is characterized by having a joint portion joined to the underside of the side surface, the joint portion extending continuously in the vertical direction from the lower end of the side structure beyond the upper end of the opening and from the lower portion to the upper portion, and the base plate being positioned overlapping the upper portion.

[0009] (2) In the structure of the railway vehicle described in (1), it is preferable that the base plate for the drive unit is formed in the shape of a roughly rectangular plate, with a longitudinal direction along the track direction of the side structure and a lateral direction in the height direction of the side structure, the longitudinal length being at least twice the length of the opening in the track direction, and the lateral length being formed within a range that fits within the fascia portion above the opening, and that the base plate can be used in common with a drive unit selected from multiple types of drive units.

[0010] The base plate for a drive device of the present invention is (3) a side structure, an opening for a side door provided in the side structure, and the The present invention is used in a railway vehicle having a frame member that reinforces a side structure and a drive device for opening and closing the side door, and is located between the drive device and the frame member and attached to the frame member. A bolt is attached to the provided nut member. a fixing portion for fixing; In order to enable the attachment of multiple types of drive devices, a drive device is provided corresponding to the type of drive device. and a mounting portion.

[0011] (4) In the base plate for the drive unit described in (3), it is preferable that the base plate is formed in an approximately rectangular plate shape, has a longitudinal direction along the track direction of the side structure and a lateral direction in the height direction of the side structure, the longitudinal length is at least twice the length of the track direction of the opening, and the lateral length is formed within a range that fits within the fascia portion above the opening, and can be used in common with drive units selected from multiple types of drive units.

[0012] According to the above-described railway vehicle body structure or drive unit base plate, the drive unit is fixed to the frame member of the side structure via the drive unit base plate, which is connected to the frame member. Therefore, if the drive unit base plate can be made to be capable of mounting multiple types of drive units, the shape and arrangement of the frame member only need to be such that the drive unit base plate can be connected, eliminating the need to consider the manufacturer or drive system of the drive unit. In other words, the shape and arrangement of the frame member do not need to be designed each time to suit the selected drive unit, and the design of the railway vehicle body can be standardized. This can improve the manufacturing efficiency of railway vehicles.

[0013] It is desirable that the base plate for the drive unit be formed in a rectangular shape with a longitudinal length that is at least twice the length of the opening for the side door in the track direction and a transverse length that fits within the fascia portion above the opening.By forming it in this manner, it becomes possible to attach many of the commonly used drive units. [Effects of the Invention]

[0014] According to the above-described body structure or drive unit base plate, it is possible to standardize the design of the railway vehicle regardless of the type of drive unit. [Brief explanation of the drawings]

[0016] The following detailed description will be given of an embodiment of a railway vehicle body structure (hereinafter simply referred to as body structure) and a drive unit base plate according to the present invention with reference to the drawings. Note that the drawings used in the description do not necessarily accurately represent the shapes and dimensions.

[0017] (Regarding railway vehicles) First, the schematic configuration of a railway vehicle 1 that uses a body structure according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a side view of the railway vehicle 1 according to this embodiment. Note that the left-right direction in Fig. 1 corresponds to the track direction of the railway vehicle 1, and the height direction in Fig. 1 corresponds to the vertical direction of the railway vehicle 1.

[0018] The railway vehicle 1 is, for example, a stainless steel vehicle used as a commuter vehicle, and as shown in Fig. 1, has a vehicle body structure 2 and a bogie 3 that supports the vehicle body structure 2. Note that the use of the railway vehicle 1 as a commuter vehicle is merely an example, and it may also be an express vehicle.

[0019] The vehicle body structure 2 is configured to form a hexahedron and is made up of an underframe 21 that forms the floor of the railway vehicle 1, a front end body structure 22 that is erected at one end of the underframe 21 in the track direction (the left end in Figure 1) and forms the front part of the vehicle body structure 2, a transverse end body structure 23 that is erected at the other end of the underframe 21 in the track direction (the right end in Figure 1) and forms the connecting part of the vehicle body structure 2, a pair of side bodies 24 that are erected at both ends of the underframe 21 in the sleeper direction and form the side parts of the vehicle body structure 2, and a roof body structure 25 that is connected to the upper end of the front end body structure 22, the upper end of the transverse end body structure 23, and the upper ends of the pair of side bodies 24 and forms the roof part of the vehicle body structure 2.

[0020] The side structure 24 is provided with a side door 26 and windows 27A, 27B, 27B, and 27C for passengers to board and disembark. The side door 26 is a double-hinged door in which two door bodies slide in opposite directions. The side structure 24 is formed by joining together a front-side end window block 241 having a window 27A, a rear-side end window block 242 having a window 27C, two sets of intermediate window blocks 243 having windows 27B, and three sets of side entrance blocks 244 having side doors 26. The numbers of intermediate window blocks 243 and side entrance blocks 244 are merely examples and are not limited thereto. For example, three sets of intermediate window blocks and four sets of side entrance blocks may be used.

[0021] The upper portions of the vehicle body structure 2 above the side doors 26 and windows 27A, 27B, 27B, and 27C are called the fascia portion 28, the lower portions below the windows 27A, 27B, 27B, and 27C are called the wainscot portion 29, and the portion sandwiched between the fascia portion 28 and the wainscot portion 29 is called the soffit portion 30.

[0022] (About the structure) Next, the body structure of the railway vehicle 1 will be described with reference to Figures 2 to 9. Figure 2 is a view of the periphery of the side entrance block 244 of the side body structure 24 as seen from the inside of the vehicle body structure 2. Figure 3 is a partially enlarged view of portion A in Figure 2, with the drive unit base plate 34 omitted. Figure 4 is a partially enlarged view of portion A in Figure 2. Figure 5 is a cross-sectional view taken along line BB in Figure 2. Figure 6 is a cross-sectional view taken along line CC in Figure 2. Figure 7 is a partially enlarged view of portion D in Figure 3. Note that the shape of the gusset 58 in Figure 7 is partially represented by a two-dot chain line to make the configuration of the first vertical frame 56 easier to see. Figure 8 is a cross-sectional view taken along line EE in Figure 7. Figure 9 is a cross-sectional view taken along line FF in Figure 7.

[0023] As shown in Figures 2, 3, and 5, the side entrance block 244 has as its main components a side entrance frame 6, a shear plate 31, two horizontal ribs 32A, 32B (an example of a rib member), and two vertical ribs 33, 33 of the fascia board portion (an example of a rib member).

[0024] The side entrance frame 6 is a rectangular frame that forms the periphery of an entrance opening 61 (an example of an opening) for the side door 26, and is made of, for example, stainless steel plate. The side entrance frame 6 includes a pair of entrance pillars 62, 62 that form both ends of the entrance opening 61 in the track direction, a lintel portion 63 that forms the upper end of the entrance opening 61, and a threshold portion 64 that forms the lower end of the entrance opening 61. The entrance opening 61 is formed by joining these parts. Each of the members 62, 63, 64 that form the side entrance frame 6 is formed with an L-shaped cross section by a first piece extending inward of the vehicle body structure 2 and a second piece parallel to the side surface of the vehicle body structure 2. Specifically, taking the lintel portion 63 as an example, as shown in FIG. 5, the L-shaped cross section is formed by a first piece 631 that extends inward of the vehicle body structure 2 and a second piece 632 that is parallel to the side surface of the vehicle body structure 2. The second piece 632 of the lintel portion 63 extends to the lower end of the roof structure 25, thereby forming the fascia panel portion 28 above the side door 26. As shown in Figure 8, the entrance posts 62, 62 are formed with an L-shaped cross section, with a first piece 621 parallel to the track direction and a second piece 622 parallel to the sleeper direction. The second piece 622 of the entrance posts 62, 62 is connected to the side outer plate (not shown) that constitutes the front end window block 241, or the side outer plate (not shown) that constitutes the rear end window block 242, or the side outer plate 51 that constitutes the intermediate window block 243.

[0025] The shear plate 31 is a plate material made of, for example, stainless steel plate, and is joined to the inner side of the second piece 632 of the lintel portion 63 in the direction of the sleepers, as shown in Figures 3 and 5. In this way, the shear plate 31 reinforces the second piece 632 (i.e., the top panel portion 28). The shear plate 31 is also connected to the roof structure 25 by a pair of connecting pieces 311 via the cross beams 32A.

[0026] As shown in FIG. 3, the cross beams 32A and 32B are arranged parallel to each other at the center of the inner surface of the second piece 632 of the lintel portion 63, extending in the track direction. The material is, for example, stainless steel. As shown in FIG. 5, the cross beams 32A and 32B have a hat-shaped cross section with a convex portion 321 protruding inward in the sleeper direction (to the left in FIG. 5) and flange portions 322 and 323 extending from the convex portion 321. The flange portions 322 and 323 are joined to the inner surface of the shear plate 31 (the surface opposite the second piece 632). A floating nut 41 is fixed to the inside of the top surface of the convex portion 321 for fixing the drive unit base plate 34 (described later). As shown in FIG. 3, four floating nuts 41 are fixed to each of the cross beams 32A and 32B, for a total of eight floating nuts 41. This floating nut 41 is a typical floating nut that includes a case and a nut that is held loosely within the case.

[0027] As shown in FIG. 3 , the pair of vertical ribs 33, 33 of the headboard section extend vertically on both sides of the cross ribs 32A, 32B in the track direction. The material is, for example, stainless steel. The cross section is formed into a hat shape by a convex portion 331 protruding inward in the direction of the sleepers and flange portions 332, 333 extending from the convex portion 331. The flange portions 332, 333 are joined to the inner surface of the second piece 632 of the lintel portion 63. A connecting piece 334 is joined to the upper end of the headboard section vertical ribs 33, 33, connecting the headboard section vertical ribs 33, 33 to the roof structure 25. A floating nut 41 for securing a drive unit base plate 34 (described later) is fixed to the inside of the top surface of the convex portion 331, near the lower side (the side doorway frame 6 side). This floating nut 41 is the same as the floating nut 41 fixed to the cross ribs 32A, 32B.

[0028] The intermediate window blocks 243, located on both sides of the side entrance block 244 in the track direction, are mainly composed of side outer panels 51 (see FIG. 6), multiple frame members, and window frames 52 (see FIG. 2). The multiple frame members refer to, for example, as shown in FIG. 2, a top panel cross rib 53 (an example of a frame member), a soffit section cross rib 54, a waist panel cross rib 55, a first vertical rib 56, and a second vertical rib 57.

[0029] The headboard cross ribs 53 are elongated members made of, for example, stainless steel, and extend the entire length of the intermediate window blocks 243 (the front end window blocks 241 and the rear end window blocks 242) in the track direction, reinforcing the headboard sections 28 of the side outer panels 51. The headboard cross ribs 53 have a hat-shaped cross section with a convex portion 531 that protrudes inward in the direction of the sleepers and flange portions 532, 533 that extend from the convex portion 531. The flange portions 532, 533 are joined to and overlapped with a shear plate (not shown) that is joined to the inner surface of the side outer panel 51. Of the three headboard cross ribs 53, floating nuts 41 are fixed inside the top surfaces of the two upper convex portions 531. Four floating nuts 41 are fixed to the headboard cross ribs 53 on each side of the side entrance block 244. The floating nut 41 is the same as the floating nut 41 fixed to the cross beams 32A and 32B.

[0030] Like the top panel cross-ribs 53, the top panel cross-ribs 54 and the wainscot cross-ribs 55 are also formed to have a hat-shaped cross section and are joined to the inner surface of the side skin 51. The two top panel cross-ribs 54 extend in the track direction between the side entrance block 244 and the window frame 52, thereby reinforcing the top panel 30 of the side skin 51. The five wainscot cross-ribs 55 extend in the wainscot portion 29 over the entire length of the side skin 51 in the track direction, thereby reinforcing the wainscot portion 29 of the side skin 51.

[0031] The first vertical ribs 56 extend vertically from the lower end to the upper end of the side structure 24 at the track-direction ends where the side entrance blocks 244 of the front end window blocks 241, the rear end window blocks 242, or the intermediate window blocks 243 are joined, thereby reinforcing the side structure 24. A connecting piece 566 is provided at the upper end of the first vertical rib 56, connecting the first vertical rib 56 to the roof structure 25. As shown in FIGS. 7 to 9 , the first vertical rib 56 is a long member formed with a Z-shaped cross section and including a first flange 561, a second flange 562 provided substantially parallel to the first flange 561, and a leg 563 connecting the end of the first flange 561 opposite the entrance opening 61 to the end of the second flange 562 on the entrance opening 61 side.

[0032] The first flange 561 is formed so as to extend continuously in the vertical direction from the upper end to the lower end of the side structure 24. The first flange 561 is joined to the side doorway frame 6 via a side outer plate (not shown) constituting the front end window block 241, or a side outer plate (not shown) constituting the rear end window block 242, or a side outer plate 51 constituting the intermediate window block 243. Specifically, below the upper end of the doorway opening 61 in the vertical direction, the first flange 561 is joined to the back surface of the second piece 622 of the entrance pillar 62 (see FIG. 8), and above the upper end of the doorway opening 61 in the vertical direction, the first flange 561 is joined to the back surface of the second piece 632 of the lintel portion 63 (see FIG. 9).

[0033] The second flange 562 has an upper portion 562a located above the upper end of the entrance / exit opening 61 in the vertical direction, and a lower portion 562b provided below the upper portion 562a.

[0034] The lower portion 562b is integral with the first flange 561 and the leg portion 563. "Integrated" here means that the first flange 561, the leg portion 563, and the lower portion 562b form a single member. The lower portion 562b extends vertically along the entrance post 62, and is joined with its surface on the first flange 561 side (the surface on the outer side in the sleeper direction) in contact with the cross beams 54, 55.

[0035] The upper portion 562a is formed of a separate member (second member 564). A more detailed explanation is as follows. A notch 565 is formed in the first vertical frame 56 by cutting a portion of the first vertical frame 56 that is located above the upper end of the entrance / exit opening 61 in the vertical direction, while leaving the first flange 561 and approximately half of the leg portion 563. The second member 564 is positioned to complement this notch 565, thereby forming the upper portion 562a. The end surface of the first flange 561 that forms the notch 565 is referred to as a notch end surface 565a, and the end surface of the leg portion 563 that forms the notch 565 is referred to as a notch end surface 565b.

[0036] The second member 564 has an L-shaped cross section and is made up of a first piece 564a forming the upper portion 562a and a second piece 564b joined to the leg portion 563. As shown in FIG. 9, the first piece 564a is positioned approximately flush with the notched end surface 565b in the sleeper direction or slightly toward the inside of the car body (lower in FIG. 9), and the second piece 564b is joined to the surface of the leg portion 563 on which the second flange 562 extends. This results in a difference in level between the upper portion 562a and the lower portion 562b of the second flange 562. More specifically, the upper portion 562a is positioned closer to the outside of the car body in the sleeper direction than the lower portion 562b. In other words, the thickness t11 of the first vertical rib 56 at the upper portion 562a of the side doorway frame 6 of the headboard 28 is thinner than the thickness t12 at the lower portion 562b. This ensures a space for installing a drive device (described later) for opening and closing the side door 26.

[0037] The upper portion 562a of the second flange 562 is formed from a separate member (second member 564), while the first flange 561 extends continuously from the upper end to the lower end of the side structure, thereby ensuring sufficient strength of the side structure.

[0038] A gusset 58 is joined to the first vertical rib 56. The gusset 58 includes a main body 581 that connects an upper portion 562a and a lower portion 562b of the second flange 562, a first joint 582 that extends from the main body 581 toward the side doorway frame 6 in the track direction and is joined to the side doorway frame 6, and a second joint 583 that extends from the main body 581 to the opposite side from the side doorway frame 6 in the track direction and is joined to the header panel horizontal rib 53.

[0039] The main body 581 has a generally Z-shaped cross section cut vertically to match the step between the upper portion 562a and the lower portion 562b (see FIG. 6). The main body 581 is joined to the first vertical rib 56 by plug welding using elongated holes 581a that penetrate the main body 581 in the thickness direction while in contact with the upper portion 562a and the lower portion 562b. This reinforces the first vertical rib 56. The first joint 582 is joined to the side doorway frame 6 by plug welding using elongated holes 582a that penetrate the first joint 582 in the thickness direction. The second joint 583 is joined to the header panel horizontal rib 53 by plug welding using elongated holes 583a that penetrate the second joint 583 in the thickness direction.

[0040] When a railway vehicle is traveling, stress tends to concentrate at the four corners of the side entrance frame 6 due to the compressive forces applied from the vehicles in front and behind. However, as described above, the gussets 58 connect the first vertical frame 56 to the side entrance frame 6, and connect the first vertical frame 56 to the horizontal frame 53 of the fascia panel, thereby providing reinforcement against the compressive forces.

[0041] The second vertical ribs 57 are made of, for example, stainless steel and have a hat-shaped cross section. The second vertical ribs 57 extend vertically from the lower end to the upper end of the side outer plate 51 at both ends of the window frame 52 in the track direction. In this way, the second vertical ribs 57 reinforce the side outer plate 51. In addition, a connecting piece 571 that connects the second vertical ribs 57 to the roof structure 25 is joined to the upper end of the second vertical ribs 57.

[0042] (Regarding the drive unit base plate) Next, the drive unit base plate 34 attached to the side structure 24 will be described. The drive unit base plate 34 is used to secure a drive unit (described later) for opening and closing the side door 26 to the side structure 24. The drive unit base plate 34 is formed in a substantially rectangular plate shape, for example, from stainless steel. As shown in FIG. 4, the drive unit base plate 34 has a longitudinal direction along the track direction, and the longitudinal dimension L11 is set to be at least twice the length of the doorway opening 61 in the track direction (dimension L21). Specifically, it is approximately 2620 mm. The drive unit base plate 34 also has a lateral direction along the vertical direction, and the lateral dimension L12 is set to be within the range that fits within the header panel portion 28 above the doorway opening 61. Specifically, it is approximately 255 mm. The dimension L12 in the short side direction is the dimension including the convex portion 341 that protrudes upward at the center in the longitudinal direction, and the dimension L13 in the long side direction of the convex portion 341 is approximately 350 mm. The dimension L14 in the short side direction excluding the convex portion 341 is sufficient if it is approximately 230 mm.

[0043] The dimensions L11, L12, L13, and L14 of the drive unit base plate 34 are the minimum dimensions necessary to enable the drive unit base plate 34 to be used with a variety of drive units. Therefore, the dimensions L11, L12, L13, and L14 may be set to be larger than the above dimensions. However, since the space available for placing the drive unit base plate 34 is limited to the space above the side doorway frame 6 and between the pair of second vertical ribs 57 of the header panel 28, the drive unit base plate 341 must be sized to fit within this space. Furthermore, the longitudinal dimension L13 of the protrusion 341 must be within a range that fits between the pair of connecting pieces 311. Additionally, since the protrusion 341 is where the nut member 73A (described later) is located, the size of the protrusion 341 is determined taking into account the position of the nut member 73A. The drive device base plate 34 has a protrusion 341 in the center in the longitudinal direction, which makes it easier to position the drive device base plate 34 while checking the positional relationship with the pair of connecting pieces 311.

[0044] The drive unit base plate 34 also has a through hole 343 (an example of a fixing portion) that penetrates the drive unit base plate 34 in the thickness direction at a position corresponding to the floating nut 41. A bolt (not shown) is passed through the through hole 343 from the inside side of the car body structure 2 (the front side in FIG. 2 or the left side in FIGS. 4 and 5) and the bolt is screwed into the floating nut 41, thereby fixing the drive unit base plate 34 to the side body structure 24. When fixing, if necessary, a spacer 42 (see FIG. 5) can be sandwiched between the side body structure 24 and the drive unit base plate 34 to adjust the position of the drive unit base plate 34 in the sleeper direction.

[0045] Furthermore, of both ends in the short side direction, a notch 342 is provided at a position corresponding to the first vertical rib 56 on the side of the side doorway frame 6 (the lower end in the drawing). The notch 342 functions as a relief to prevent interference between the drive unit base plate 34 fixed to the side structure 24 and the first vertical rib 56.

[0046] The drive unit fixed to the side structure 24 via the drive unit base plate 34 described above can be selected from three types: a drive unit 43 manufactured by company A (see FIG. 11), a drive unit 44 manufactured by company B (see FIG. 13), and a drive unit 45 manufactured by company C (see FIG. 15). The following description will be made with reference to FIGS. 10 to 15.

[0047] 11, the drive device 43 is equipped with an electric motor 431, and by operating the motor 431, a first rack and a second rack (neither of which is shown), which are arranged horizontally along the track direction within a housing 432, can be slid in opposite directions. One of the two door bodies is hung on the first rack by a connecting member 433, and the other door body is hung on the second rack by a connecting member 434, so that the first rack and the second rack slide in opposite directions to open and close the side door 26 (see FIG. 1).

[0048] As shown in Fig. 13, the drive device 44 is equipped with an electric motor 441, and by operating the motor 441, a first rack 442 and a second rack 443, which are arranged horizontally along the track direction, can be slid in opposite directions. One of the two door bodies is hung from the first rack 442 by a connecting metal fitting 444, and the other door body is hung from the second rack 443 by a connecting metal fitting 445, so that the first rack 442 and the second rack 443 slide in opposite directions to open and close the side door 26 (see Fig. 1).

[0049] As shown in Fig. 15, the drive device 45 includes an air cylinder 451 that is driven by operating air supplied from an air supply source (not shown). When the air cylinder 451 is driven, a first rod 452 and a second rod 453 that are arranged horizontally along the track direction slide in opposite directions. One of the two door bodies is hung from the first rod 452 by a connecting fitting 454, and the other door body is hung from the second rod 453 by a connecting fitting 455. As a result of the first rod 452 and the second rod 453 sliding in opposite directions, the side door 26 (see Fig. 1) is opened and closed.

[0050] The drive device base plate 34 can be provided with a mounting portion suitable for a drive device selected from the three types of drive devices 43, 44, and 45. Specifically, this is as follows.

[0051] First, a description will be given of the case where the driving device 43 is selected. When the driving device 43 is selected, the driving device base plate 34 is provided with nut members 71A, 71B, 72A, 72B, 72C, and 72D as mounting portions, as shown in FIG.

[0052] All of the nut members 71A, 71B, 72A, 72B, 72C, and 72D are joined by welding to the rear surface of the drive unit base plate 34 (i.e., the surface on the side of the side structure 24). The positional relationship of the nut members 71A, 71B, 72A, 72B, 72C, and 72D is determined by the drive unit 43, but because rib members that constitute the side structure 24 are located on the rear surface side of the drive unit base plate 34, the nut members 71A, 71B, 72A, 72B, 72C, and 72D are provided to avoid the positions of the rib members.

[0053] Specifically, of the nut members 71A and 71B joined to both ends of the drive unit base plate 34 in the track direction, the nut member 71A is positioned between the upper two of the three header cross bones 53, and the nut member 71B is positioned below the second header cross bone 53 from the top. The nut members 71A and 71B are the same member, and each has two screw holes.

[0054] Furthermore, of the nut members 72A, 72B joined to the center of the drive unit base plate 34 in the track direction, the nut member 72A is positioned between the cross bones 32A, 32B (see Figures 3 and 5), and the nut member 72B is positioned below the cross bone 32B (see Figures 3 and 5).

[0055] Of the nut members 72C and 72D joined between the center and end portions of the drive unit base plate 34 in the track direction, the nut member 72C is positioned at the same position as the nut member 72A in the vertical direction and between the header panel vertical rib 33 and the first vertical rib 56 in the track direction. The nut member 72D is positioned at the same position as the nut member 72B in the vertical direction and at the same position as the nut member 72C in the track direction. The nut members 72A, 72B, 72C, and 72D are all identical members and each have one screw hole. Furthermore, the drive unit base plate 34 has through-holes penetrating the thickness direction at positions corresponding to the nut members 71A, 71B, 72A, 72B, 72C, and 72D so that bolts can be inserted from the inner surface of the drive unit base plate 34 and screwed into the nut members 71A, 71B, 72A, 72B, 72C, and 72D.

[0056] As described above, by providing the nut members 71A, 71B, 72A, 72B, 72C, and 72D on the drive device base plate 34, the drive device 43 can be fixed as shown in FIG.

[0057] Next, a description will be given of a case where the drive unit 44 is selected. When the drive unit 44 is selected, the drive unit base plate 34 is provided with nut members 73A, 73B, 74A, 74B, and 74C as mounting portions, as shown in FIG.

[0058] The nut members 73A and 73B are joined by welding to the back surface (i.e., the surface on the side structure 24 side) of the protrusion 341 of the drive unit base plate 34. The nut members 74A, 74B, and 74C are joined by welding to the front surface (i.e., the surface opposite to the surface on the side structure 24 side) of the drive unit base plate 34.

[0059] The relative positions of the nut members 73A, 73B, 74A, 74B, and 74C are determined by the drive unit 44. However, because the rib members constituting the side structure 24 are located on the rear surface of the drive unit base plate 34, the nut members 73A and 73B are provided to avoid the rib members. Specifically, the nut member 73A, which is located on the rear surface of the protrusion 341 of the drive unit base plate 34, is positioned above the cross frame 32A (see FIGS. 3 and 5), and the nut member 73B is positioned between the cross frames 32A and 32B (see FIGS. 3 and 5). The nut members 73A and 73B are all identical members and each have one screw hole. Furthermore, the drive unit base plate 34 has through-holes penetrating the thickness direction at positions corresponding to the nut members 73A and 73B so that bolts can be inserted from the inner surface of the drive unit base plate 34 and screwed into the nut members 73A and 73B.

[0060] The nut members 74A, 74B, and 74C are positioned side by side at the lower end of the drive unit base plate 34, and are all positioned identically in the vertical direction. A pair of nut members 74A is positioned in the center of the drive unit base plate 34 in the track direction, and nut members 74C are positioned at both ends in the track direction, with nut member 74B positioned between nut members 74A and 74C. Note that the nut members 74A, 74B, and 74C are all identical members, and each has two screw holes.

[0061] By providing the nut members 73A, 73B, 74A, 74B, and 74C on the drive device base plate 34 as described above, the drive device 44 can be fixed as shown in FIG.

[0062] Next, a description will be given of a case where the driving device 45 is selected. When the driving device 45 is selected, the driving device base plate 34 is provided with nut members 75A, 75B, 75C, 75D, 75E, and 76 as mounting portions, as shown in FIG.

[0063] The nut members 75A, 75B, 75C, 75D, and 75E are joined by welding to the back surface of the drive unit base plate 34 (i.e., the surface facing the side structure 24) in a state where they are arranged at equal intervals from the center outward in the track direction in the order of nut members 75A, 75B, 75C, 75D, and 75E. Furthermore, the nut member 76 is joined by welding to the front surface of the drive unit base plate 34 (i.e., the surface opposite to the surface facing the side structure 24).

[0064] The relative positions of the nut members 75A, 75B, 75C, 75D, 75E, and 76 are determined by the drive unit 45. However, because the rib members constituting the side structure 24 are located on the rear surface of the drive unit base plate 34, the nut members 75A, 75B, 75C, 75D, and 75E are provided to avoid the rib members. Specifically, the nut members 75A and 75B are located between the cross ribs 32A and 32B (see FIGS. 3 and 5), the nut member 75C is located between the top panel vertical rib 33 and the first vertical rib 56, and the nut members 75D and 75E are located between the upper two of the three top panel cross ribs 53. The nut members 75A, 75B, 75C, 75D, and 75E are all identical members, and each has one screw hole. In addition, at positions on the drive unit base plate 34 corresponding to the nut members 75A, 75B, 75C, 75D, and 75E, through holes are provided that penetrate the thickness direction so that bolts can be inserted from the inner surface of the drive unit base plate 34 and screwed into the nut members 75A, 75B, 75C, 75D, and 75E.

[0065] Furthermore, each of the two nut members 76 is positioned above and between nut members 75B and 75C, and is positioned in the same vertical direction. The two nut members 76 are the same member, and each has two screw holes.

[0066] As described above, by providing the nut members 75A, 75B, 75C, 75D, 75E, and 76 on the drive device base plate 34, the drive device 45 can be fixed as shown in FIG.

[0067] (About the effects) As described above, the body structure according to this embodiment is (1) In a railway vehicle structure comprising a side structure 24, an opening for a side door 26 provided in the side structure 24 (e.g., an entrance / exit opening 61), and frame members (e.g., cross beams 32A, 32B, header vertical frame 33, header horizontal frame 53) reinforcing the side structure 24 above the opening (entrance / exit opening 61), and in which a drive unit (e.g., drive unit 43 or drive unit 44 or drive unit 45) for opening and closing the side door 26 is fixed to the frame members (cross beams 32A, 32B, header vertical frame 33, header horizontal frame 53), the drive unit is fixed to the frame members (cross beams 32A, 32B, header vertical frame 33, header horizontal frame 53) via a drive unit base plate 34 connected to the frame members (cross beams 32A, 32B, header vertical frame 33, header horizontal frame 53).

[0068] (2) In the structure of the railway vehicle described in (1), it is preferable that the base plate 34 for the drive unit is formed in the shape of a roughly rectangular plate, with a longitudinal direction along the track direction of the side structure 24 and a transverse direction in the height direction of the side structure 24, that the longitudinal length (dimension L11) is at least twice the length (dimension L21) of the opening (e.g., entrance / exit opening 61) in the track direction, and that the transverse length (dimension L12) is formed within a range that fits within the fascia portion 28 above the opening (entrance / exit opening 61), and that it can be used in common with a drive unit (drive unit 43, drive unit 44, or drive unit 45) selected from multiple types of drive units.

[0069] Moreover, the drive unit base plate 34 according to this embodiment is (3) Used in a railway vehicle 1 including a side structure 24, an opening (e.g., entrance / exit opening 61) for a side door 26 provided in the side structure 24, frame members (e.g., cross beams 32A, 32B, header vertical frame 33, header horizontal frame 53) reinforcing the side structure 24 above the opening (e.g., entrance / exit opening 61), and a drive unit (e.g., drive unit 43, drive unit 44, or drive unit 45) for opening and closing the side door 26, and between the drive unit (drive unit 43, drive unit 44, or drive unit 45) and the frame members (cross beams 32A, 32B, header vertical frame 33, header horizontal frame 53) and is characterized by having a fixing portion (e.g., through hole 343) for fixing to a bone member (horizontal bones 32A, 32B, vertical bones 33 of the top panel, horizontal bones 53 of the top panel), and an attachment portion (e.g., nut members 71A, 71B, 72A, 72B, 72C, 72D corresponding to the drive unit 43, or nut members 73A, 73B, 74A, 74B, 74C corresponding to the drive unit 44, or nut members 75A, 75B, 75C, 75D, 75E, 76 corresponding to the drive unit 45) for attaching a drive unit (drive unit 43 or drive unit 44 or drive unit 45).

[0070] (4) In the base plate 34 for the drive unit described in (3), it is preferable that it is formed in the shape of an approximately rectangular plate, with a longitudinal direction along the track direction of the side structure 24 and a transverse direction in the height direction of the side structure 24, that the longitudinal length (dimension L11) is at least twice the length (dimension L21) of the track direction of the opening (e.g., entrance / exit opening 61), and that the transverse length (dimension L12) is formed within a range that fits within the fascia portion 28 above the opening (entrance / exit opening 61), and that it can be used in common with a drive unit (drive unit 43, drive unit 44, or drive unit 45) selected from multiple types of drive units.

[0071] According to the above-described railway vehicle body structure or drive unit base plate 34, the drive unit (drive unit 43 or drive unit 44 or drive unit 45) is fixed to the frame members (cross ribs 32A, 32B, header vertical ribs 33, header horizontal ribs 53) of the side body structure 24 via the drive unit base plate 34 which is coupled to the frame members (cross ribs 32A, 32B, header vertical ribs 33, header horizontal ribs 53). Therefore, if the drive unit base plate 34 is designed to be capable of mounting a plurality of types of drive units, the shape and arrangement of the frame members (cross ribs 32A, 32B, header vertical ribs 33, header horizontal ribs 53) only need to be such that the drive unit base plate 34 can be coupled thereto, and there is no need to consider the manufacturer or drive system of the drive unit. In other words, the shape and arrangement of the frame members (cross ribs 32A, 32B, headboard vertical ribs 33, headboard cross ribs 53) do not need to be designed each time to suit the selected drive unit, and the design of the car body structure 2 of the railway car 1 can be standardized. Therefore, the manufacturing efficiency of the railway car 1 can be improved.

[0072] The base plate 34 for the drive unit is desirably formed in a rectangular shape with a longitudinal length (dimension L11) that is at least twice the length (dimension L21) of the opening (e.g., entrance / exit opening 61) in the track direction, and a lateral length (dimension L12) that fits within the fascia portion 28 above the opening (entrance / exit opening 61).By forming it in this manner, it becomes possible to attach many of the commonly used drive units (drive units 43, 44, 45).

[0073] The above-described embodiment is merely illustrative and does not limit the present invention in any way. Therefore, the present invention can naturally be improved and modified in various ways without departing from the spirit and scope of the present invention. For example, the number and positions of the fixing portions (through holes 343) provided on the drive unit base plate 34 are not limited to those of the present embodiment. Since the drive unit base plate 34 is subject to the mass of the drive unit and the door body, as well as impacts when the door body slides, the number of fixing portions (through holes 343) may be adjusted as appropriate to withstand the above mass and impacts.

[0074] In addition, in this embodiment, the arrangement of the drive unit base plate 34 and drive units 43, 44, 45 is explained using the side entrance / exit block 244 sandwiched between intermediate window blocks 243 on both sides as an example, but the same applies to the side entrance / exit block 244 sandwiched between the front side car end window block 241 and the intermediate window block 243, and the side entrance / exit block 244 sandwiched between the intermediate window block 243 and the rear side car end window block 242.
