Description

  The present invention relates to a railway vehicle structure.

  In recent years, various types of electrical equipment such as cabin lighting and liquid crystal display panels have been provided in railway vehicle structures. Therefore, a large number of wirings used for transmission / reception of signals to / from electric devices are arranged in the railway vehicle structure. These wires are generally bundled for each type, and are arranged along the longitudinal direction of the vehicle while being held by a wire holding structure attached to the structure.

  With respect to such a wiring holding structure, for example, in Patent Document 1, there are a fixing portion fixed to a roof structure, a connection portion extending downward from the fixing portion, and a protective member that protrudes horizontally from the connection portion and has elasticity. And a structure in which a wiring bundle is mounted on the mounting portion and fixed with a fixing band.

JP 2010-188951 A

  By the way, in the conventional wiring holding structure described above, when there are a plurality of wiring bundles, a mounting portion is provided on the opposite side across the connecting portion, and the plurality of wiring bundles are arranged in parallel. However, in such a structure, for example, when a part of the wiring bundle located on the front side when viewed from the inside is to be branched to the back side, a notch or the like for passing the branching portion of the wiring is provided in the connecting portion. It is necessary to provide it. Further, even if the notch is provided, it is necessary to place the branch portion of the wiring on the wiring bundle located on the far side, and the wiring may be complicated. Furthermore, since it is difficult to visually recognize the wiring bundle on the back side from the indoor side, there is a problem that it is difficult to ensure workability such as inspection and expansion of wiring.

  The present invention has been made to solve the above problems, and even when the wiring is branched, it can be avoided that the wiring becomes complicated with a simple configuration, and the visibility of the attached bundle of wirings can be avoided. The purpose of the present invention is to provide a railway vehicle structure capable of securing the above.

  In order to solve the above problems, a railway vehicle structure according to the present invention is a railway vehicle structure including a wiring holding structure that holds a plurality of wiring bundles in which wirings connected to electronic devices are bundled. A suspension groove fixed to the roof structure or side structure of the railway vehicle structure via an adapter, a mounting plate extending along the suspension groove, on which the wiring bundle is placed, and a predetermined interval in the suspension groove A holding member that holds the mounting plate, and the holding member has a first holding piece to which the first mounting plate is fixed, and a second member to which the second mounting plate is fixed. And the first holding piece and the second holding piece are different in the height direction of the railway vehicle structure.

  In this railway vehicle structure, in the holding member that holds the mounting plate, the first holding piece to which the first mounting plate is fixed and the second holding piece to which the second mounting plate is fixed are provided. It is different. The holding member itself is fixed to the hanging groove with a predetermined interval. With such a configuration, a sufficient space is ensured in both sides of the wiring bundle placed on the first placement board and on both sides of the wiring bundle placed on the second placement board. Even if no notch etc. are provided in the hanging groove, the branch route is prevented from being blocked by other wire bundles by passing the wire branch part between the holding members when branching the wire bundle. it can. Further, in this railway vehicle structure, the wiring bundle can be easily visually recognized from between the holding members by arranging the holding members at a predetermined interval. Therefore, workability of work such as wiring inspection and expansion (addition) is ensured.

  The first holding piece faces the inside of the railway vehicle structure, while the second holding piece faces the outside of the railway vehicle structure, and the first mounting plate and the second mounting plate are provided with the hanging groove. It is preferable that it is located on both sides of the position. In this case, a sufficient space can be secured on both sides of the wiring bundle placed on the first placement board and on both sides of the wiring bundle placed on the second placement board. The complexity of wiring can be avoided more suitably.

  Further, both the first holding piece and the second holding piece face the inside of the railway vehicle structure, the first placement plate is located inside the railway vehicle structure with respect to the hanging groove, and the second placement piece It is preferable that the plate is located directly below the hanging groove. In this case, the visibility of the wiring bundle can be further improved. Moreover, the complexity of wiring can also be avoided by shifting the position of the first mounting plate and the position of the second mounting plate.

  In addition, both the first holding piece and the second holding piece face the inside of the railway vehicle structure, and both the first placement plate and the second placement plate are located directly below the suspension groove. Preferably it is. In this case, the visibility of the wiring bundle can be further improved. Moreover, the weight balance of a holding member becomes favorable by positioning a 1st mounting board and a 2nd mounting board directly under a suspension groove.

  The third holding piece further has a third holding piece facing the inside of the railway vehicle structure at the same stage as the second holding piece, and the third mounting plate fixed to the third holding piece is positioned directly below the suspension groove. It is preferable. In this case, even if the wiring bundle is further arranged, the complexity of the wiring can be avoided. Moreover, the weight balance of the holding member is also maintained.

  The fourth holding plate further includes a fourth holding piece that faces the inside of the railway vehicle structure at a lower stage than the second holding piece, and the fourth mounting plate that is fixed to the fourth holding piece is the second mounting plate. It is preferable that it is located just below. In this case, even if the wiring bundle is further arranged, the complexity of the wiring can be avoided. In addition, the wiring bundle placed on the fourth placement board can be routed close to the electronic device.

  The fifth holding plate further includes a fifth holding piece that faces the outside of the railway vehicle structure in the same stage as the first holding piece, and the fifth mounting plate fixed to the fifth holding piece is the second mounting plate. It is preferable to be located inside the railway vehicle structure. In this case, even if the wiring bundle is further arranged, the complexity of the wiring can be avoided. Further, the space between the holding member and the roof structure or the side structure can be effectively used.

  Further, it is preferable that the second holding piece is lower than the first holding piece. Thereby, it becomes possible to make the shape of the holding member conform to the shape of the roof structure and the side structure of the railway vehicle structure, and the space can be used effectively.

  According to the present invention, even if the wiring is branched, it is possible to avoid the wiring from becoming complicated with a simple configuration, and it is possible to ensure the visibility of the attached wiring bundle.
