  The underframe 2 is configured to extend substantially horizontally. More specifically, the underframe 2 is convexly curved upward in the longitudinal direction of the vehicle in a side view, and is inclined downward from the central portion in the longitudinal direction of the vehicle toward both ends in the longitudinal direction of the vehicle ( FIG. 1 shows this inclination exaggerated with a two-dot chain line). Thereby, even if there are many passengers in the passenger compartment formed inside the vehicle body 1, it is possible to prevent the underframe 2 from being bent downward.

  The side structure 3 is formed with a side entrance 4 used for passengers getting on and off. The vehicle body 1 includes a side entrance frame 5 attached to the periphery of the side entrance 4 for reinforcement and makeup. The vehicle body 1 includes a door 6 that opens and closes the side entrance 4. The side structure 3 is provided with a door pocket 7 that can accommodate the door 6 adjacent to the side entrance 4 in the longitudinal direction of the vehicle. The door 6 is slidable in the longitudinal direction of the vehicle between an open position where the door 6 is housed in the door pocket 7 and opens the side doorway 4 and a closed position where the door 6 exits from the doorbag 7 and closes the side doorway 4. Is provided.

  In the present embodiment, two side entrances 4 are arranged at one end and the other end of each side structure 3 in the vehicle longitudinal direction. As an example only, in this embodiment, the door 6 is a one-sided sliding door, and is configured by one door member. One door member and one door pocket 7 are connected to one side doorway 4. It corresponds. As an example only, in this embodiment, each door pocket 7 is adjacent to the corresponding side doorway 4 at the vehicle longitudinal direction center side with respect to the corresponding side doorway 4. However, the number and arrangement of the side doors 4 are not particularly limited. Further, the door 6 may be of a double door type (may be constituted by two door members), and the arrangement of the door pocket 7 with respect to the side doorway 4 is not limited.

  FIG. 2 is a plan view showing the lower edge of the side doorway 4 and the bottom portion of the door pocket 7, and FIG. 3 is a cross-sectional view showing the lower edge of the side doorway 4 and the bottom portion of the door pocket 7. As shown in FIGS. 2 and 3, the vehicle body 1 includes a hull assembly 10 disposed along the lower edge of the side door 4. The hull assembly 10 includes a hull 11 and a hull heater 12. The huller 11 is formed in a long flat plate shape in the vehicle longitudinal direction. The hull heater 12 is attached to the lower surface of the hull 11.

(Function)
A railway vehicle body 1 according to an embodiment of the present invention includes a door 6 that opens and closes a side entrance 4, a frame 2 that has a recess 2 a that extends in the longitudinal direction of the vehicle along the side entrance 4 and opens upward, And a hull assembly 10 disposed along the lower edge of the side doorway 4. The hull assembly 10 includes a hull 11 that closes the concave portion 2a from above, and a hull heater 12 that is attached to the lower surface of the hull 11 and accommodated in the concave portion 2a. The vehicle body 1 includes a frame cover member 40 that is interposed between the hull assembly 10 and the frame 2, is fitted in the recess 2 a to cover the inner surface of the recess 2 a, and houses the hull heater 12.

  Even if the water melted by the hulling heater 12 permeates from the upper surface side to the lower surface side of the hulling paper 11, the water can be received by the underframe cover member 40 (in particular, the bathtub portion 44 in this embodiment). it can. It can suppress that water adheres to the frame 2, and can suppress that the frame 2 rusts.

  Moreover, you may provide the 1st sealing material 91 which seals the clearance gap between the base frame cover member 40 and the contact member which contact | abuts the base frame cover member 40 in the lower surface side of the huller 11. According to the above configuration, the water received by the frame cover member 40 by the first seal member 91 enters the gap between the frame cover member 40 and the member that contacts the frame cover member 40, and the frame cover member 40. Reaching the surface of another member can be suppressed. Since the 1st sealing material 91 is provided in the lower surface side of the huller 11, it can prevent that a passenger steps on at the time of boarding / alighting. Therefore, the lifetime of the first sealing material 91 is extended.

  And the drainage opening 45 opened in the inner space of the bathtub part 44 of the frame cover member 40 may be provided. This drain port 45 may be communicated with the outside of the frame cover member 40 via a drain pipe. As an example of this “outside”, outside air may be used, or a frame drain part (not shown) formed on the frame 2 for draining rainwater may be used. Since drainage is enabled, it is possible to suppress deterioration of the frame cover member 40 with water, and it is possible to protect the hulling heater 12 housed in the bathtub portion 41 from water.

  The bottom wall 42 of the frame cover member 40 is inclined downward toward the outer side in the vehicle longitudinal direction, and the drain port 45 may be open to the outer side in the vehicle longitudinal direction of the bottom wall 42. For this reason, the water that has reached the underframe cover member 40 flows down toward the outer side in the vehicle longitudinal direction under its own weight. Since the drain opening 45 is opened ahead, the drainage is high. The frame 2 is inclined so as to protrude upward at the center in the longitudinal direction of the vehicle, and the frame cover member 40 is easily inclined to the bottom wall 42 when formed so as to follow this inclination. Can be attached and can be easily assembled with the frame 2.

  The frame cover member 40 may be formed of any material, but may be formed of a steel plate material in the same manner as the frame 2 for joining with the frame 2 by fillet welding. In that case, there is a possibility that the underwater frame cover member 40 is rusted by the received water. However, even in that case, the ease of repair or replacement of the frame cover member 40 is much higher than that of the frame 2, which contributes to long-term operation of the vehicle body 1. In order to replace the underframe cover member 40, the hull assembly 10 may be removed. Since the frame cover member 40 is loosely fitted in the recess 2a, the operation of removing the frame cover member 40 from the frame 2 and the operation of attaching it to the frame 2 can be easily performed.

  The second sealing material 92 may be provided along the side end surface of the huller 11. Moreover, the gasket 93 may be interposed between the lower surface of the huller 11 and the contact member (the flat plate portion 5b). According to this, even if the water melted by the hulling heater 12 enters from the upper surface side to the lower surface side of the hulling paper 11, the second sealing material 92 prevents the water from entering. Even if water permeates into the lower surface side of the huller 11, the gasket 93 is interposed between the lower surface of the huller 11 and the upper surface of the flat plate portion 5b disposed below it. It can prevent passing through the lower surface side of the huller 11. Thus, since the triple seal is provided in the approach path until the water outside the huller 11 reaches the surface of the frame 2, the rust prevention effect of the frame 2 is high.

  There is a possibility that the hull assembly 10 may be removed and reattached more frequently than the underframe cover member 40 in order to maintain the hull heater 12. In that case, as long as the third sealing material 93 is broken, only the hull assembly 10 is attached to the frame 2 without breaking the first sealing material 91 and removing the frame cover member 40 from the frame 2. Can be removed from. There are few incidental operations such as removal of parts other than the parts to be maintained, and the maintenance work of the hulling heater 12 can be performed easily.

  When the hull assembly 10 is reinstalled, the third sealing material 93 needs to be re-installed. In this case, if the construction is insufficient, a gap is formed at the seam between the hull assembly 10 and the door pocket bottom wall 33, and there is a possibility that water may enter downward from here. In this embodiment, the recessed part 2a and the frame cover member 40 are extended to the door pocket corresponding part, and the joint is positioned immediately above the frame cover member 40 (particularly, the bathtub portion 44). Therefore, even if the construction is insufficient and the entry of water is allowed, the water can be received by the frame cover member 40, and the rust prevention effect of the frame 2 is improved.

  During traveling of the vehicle, ice and snow may adhere to the outer surface of the door 6 that is in the closed position and forms the exterior of the vehicle. When the door 6 slides to the open position, the ice and snow may fall into the door storage space. A door pocket cover member 50 is also provided on the inner bottom of the door pocket 7. Thereby, the water produced by melting by the snow and snow or the door pocket heater 32 can be received by the door pocket cover member 50, and such water can be prevented from reaching the surface of the underframe 2 (door pocket corresponding portion). A drain outlet 54 is also formed at the bottom of the door cover member 50, so that water received by the door cover member 50 can be drained. Thereby, deterioration of the door cover member 50 can be prevented, and the smooth operation of the door 6 can be realized.

  The embodiment has been described so far, but the above configuration can be appropriately changed, added, and / or deleted within the scope of the gist of the present invention.
