  The interior panel structure of a door pocket may be required to be lightweight and thin, to have high structural strength, and to be efficiently manufactured.

  Accordingly, an object of the present invention is to provide an interior panel structure for a railway vehicle that can be reduced in weight and thickness, has high structural strength, and can be efficiently manufactured.

  In order to solve the above-described problem, an aspect of the present invention is an interior panel structure that is connected to a railway vehicle structure on three sides, and the remaining one side excluding the three sides is separated from the railway vehicle structure. And a long plate-like reinforcing member provided along the one side on a part of one plate surface of the panel member, and the reinforcing member is formed of the panel member. A plate surface covering portion that covers the partial area, and an end surface covering portion that is integrally continuous with the plate surface covering portion and covers an end surface on the one side of the panel material, A first plate portion that is in surface contact with the one plate surface of the panel material; and a second plate portion that is connected to the first plate portion and is opposed to the one plate surface of the panel material at an interval. Each of the first plate portion and the second plate portion extends in a longitudinal direction of the reinforcing material, and Are arranged in parallel in one direction along the one plate surface of interlinking the panel material, the thickness of the second plate portion in the thickness direction of the panel material is thicker configured than the thickness of the first plate portion.

  The “plate surface” here refers to a pair of surfaces (main surfaces) having the largest surface area among the surfaces of the panel material. In addition, the “end face” refers to a face of an end portion that connects the pair of plate surfaces of the panel material.

  According to the above configuration, in the plate surface covering portion of the reinforcing material, the first plate portion that is in surface contact with the one plate surface of the panel material and the first plate portion are connected, and the gap between the one plate surface of the panel material and the gap is provided. The panel member and the reinforcing member are arranged in parallel in one direction along one plate surface of the panel member extending in the longitudinal direction and orthogonal to the longitudinal direction of the reinforcing member. As a result, a hollow structure is formed in the interior panel structure. Thereby, the panel material is strongly reinforced with the reinforcing material. In addition, since the reinforcing material has a high structural strength by forming a continuous portion in which the plate surface covering portion and the end surface covering portion are integrally continuous, the vicinity of the end surface of the panel material is strongly reinforced. it can.

  By providing the reinforcing material having such a configuration along a side of the panel material separated from the railway vehicle structure in a partial region of one panel surface of the panel material, a portion that requires reinforcement of the panel material is provided. Can be properly reinforced. Therefore, it is not necessary to increase the overall thickness of the panel material in order to reinforce the panel material, and the panel material can be reduced in weight and thickness. Furthermore, by making the thickness of the first plate portion of the reinforcing material thinner than the thickness of the second plate portion, the weight of the reinforcing material can be reduced and the thickness can be reduced. Therefore, it is possible to reduce the weight and thickness of the interior panel structure while strongly reinforcing the interior panel structure with the reinforcing material.

  Moreover, since the 1st reinforcement material is comprised by the simple structure with which the board surface coating | coated part and the end surface coating | coated part were integrated, it can manufacture easily. Further, by integrating the plate surface covering portion and the end surface covering portion of the first reinforcing material, the number of components of the interior panel structure can be reduced, and the interior panel structure can be efficiently manufactured.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a front view showing a door pocket 2 and its periphery of a railway vehicle 1 according to the first embodiment. FIG. 2 is a perspective view showing the structure of the interior panel structure 4 on the vehicle interior side. FIG. 3 is a perspective view showing the structure of the interior panel structure 4 on the inner side of the door pocket.

  As shown in FIG. 1, a pair of door pockets 2 are provided on both sides of a side door 1 a that is opened and closed by both sliding doors 3 of a railway vehicle 1. Each door pocket 2 includes an interior panel structure that faces the sliding doors 3 housed in the door pocket 2 at an interval from the vehicle interior side. The interior panel structure 4 is entirely formed in a rectangular shape, and has an upper side 4a, a lower side 4b, a first side side 4c, and a second side side 4d located on the opposite side of the first side side 4c. The interior panel structure 4 is connected to the railcar structure 14 at three sides of the upper side 4a, the lower side 4b, and the first side 4c, and the second side 4d is separated from the railcar structure 14.

  As shown in FIGS. 2 and 3, the interior panel structure 4 includes a panel material 6, a first reinforcing material 7, a second reinforcing material 8, a handrail mounting portion 9, a handrail 10, a mounting bracket 11, a finger protection material 12, and a structure mounting. The unit 13 is provided. The panel material 6 is a composite panel material formed by laminating a plurality of plate materials. As an example, a resin plate 6i made of a non-foamed and solid thermoplastic resin is used as an intermediate layer on both surfaces of the resin plate 6i. The metal plates 6j and 6k are laminated (see FIG. 4). The metal plate 6k is disposed on the first plate surface 6e side facing the vehicle inner side. The metal plate 6j is disposed on the second plate surface 6f side facing the inside of the door pocket 2. The resin plate 6i and the metal plates 6j and 6k are bonded together by welding. In general, the interior material of a railway vehicle is composed of an aluminum-based decorative board or the like, which is obtained by laminating and bonding printing paper and a resin board on one side of an aluminum board, an aluminum coating board, or the like. The panel material 6 is thicker and has a lower specific gravity than these conventional interior materials. For this reason, the panel material 6 has high rigidity, is relatively light, and has a characteristic that warpage is unlikely to occur.

  The panel material 6 has a predetermined thickness D1 (see FIG. 4) and is formed in a rectangular shape. The panel material 6 includes an upper side 6a, a lower side 6b, a first side side 6c, and a second side side 6d corresponding to the upper side 4a, the lower side 4b, the first side side 4c, and the second side side 4d, respectively, in order. Have As an example, the thickness D1 of the panel material 6 is set to be equal to or less than the thickness D2 of the second plate portion 7a3 of the first reinforcing material 7 described later. The panel material 6 has the 1st board surface 6e, the 2nd board surface 6f, and the end surface 6g facing the interior panel structure 4 in the other door pocket 2 in the vicinity of the 2nd side 6d. The “separation” here refers to the case where the entire area of the second side 6d is separated from the railcar structure 14, and a part of the second side 6d near both ends in the longitudinal direction (for example, the first side A portion having a length of about several to tens of percent of the vertical length of the two side sides 6d) is connected to the railway vehicle structure 14 and the remaining portion is separated from the railway vehicle structure 14. Includes both. As an example, the panel material 6 is a composite material in which metal plates are stacked on both surfaces of a resin plate.

  The 1st reinforcement material 7 is formed in the elongate plate shape as a whole, and has the board surface coating | coated part 7a, the end surface coating | coated part 7b, and the protrusion part 7c. The plate surface covering portion 7 a covers a region near the second side 6 d of the second plate surface 6 f of the panel material 6 over the longitudinal (vertical) direction of the panel material 6.

  FIG. 4 is a cross-sectional view of the interior panel structure 4. FIG. 5 is a cross-sectional view of the interior panel structure 4 showing the positional relationship between the first reinforcing material 7 and the second reinforcing material 8. 4 and 5 show the interior panel structure 4 in a cross-section orthogonal to the longitudinal direction, respectively. In FIG. 5, the lower part of the 3rd board part 7a4 and the 2nd reinforcement material 8 piled up on it is shown in a cross section. As shown in FIG. 4, the plate surface covering portion 7 a includes a plurality of first plate portions 7 a 1, connecting portions 7 a 2, and second plate portions 7 a 3. The first plate portion 7 a 1 is in surface contact with the second plate surface 6 f of the panel material 6. The connecting portion 7a2 is located between the first plate portion 7a1 and the second plate portion 7a3, and connects the first plate portion 7a1 and the second plate portion 7a3. The second plate portion 7a3 continues to the connecting portion 7a2 and opposes the second plate surface 6f of the panel material 6 with a gap of a certain distance G.

  Each of the first plate portion 7a1 and the second plate portion 7a3 extends in the longitudinal direction of the first reinforcing member 7, and is orthogonal to the longitudinal direction of the first reinforcing member 7 and is in one direction along the second plate surface 6f. (For example, the longitudinal direction of the railway vehicle 1 and the short direction of the first reinforcing member 7) are alternately and repeatedly arranged. Thereby, the plate | board surface coating | coated part 7a has a corrugated cross section. As shown in FIGS. 3 and 5, the first reinforcing member 7 further includes a third plate portion 7 a 4 extending from a plurality of second plate portions 7 a 3 from one side in the longitudinal direction of the first reinforcing member 7.

  The thickness D2 of the second plate portion 7a3 in the thickness direction of the panel material 6 is set to be thicker than the thickness D3 of the first plate portion 7a1. The thickness D2 of the second plate portion 7a3 can be set as appropriate. For example, in the door pocket 2, the thickness D2 is set in a range where the sliding door 3 and the first reinforcing member 7 do not contact each other. The distance G between the second plate surface 6f of the panel material 6 and the second plate portion 7a3 in the thickness direction of the panel material 6 is set to the same distance as the thickness D3 of the first plate portion 7a1. In addition, the distance G between the second plate surface 6f of the panel material 6 and the third plate portion 7a4 in the thickness direction of the panel material 6 is also set to a distance corresponding to the thickness D3 of the first plate portion 7a1. In the one direction, the pitch between the adjacent first plate portions 7a1 (the interval between the centers P1 of the adjacent first plate portions 7a1) and the pitch between the adjacent second plate portions 7a3 (the adjacent second plate portions). The distance between the centers P2 of 7a3 is substantially the same as an example, but is not limited to this and may be different from each other. When a cross section perpendicular to the longitudinal direction of the first reinforcing member 7 is viewed, the connecting portion 7a2 extends from a part of the upper surface of the first plate portion 7a1 so as to be continuous with the second plate portion 7a3. Thus, by providing the connection part 7a2 in the upper surface of the 1st board part 7a1, the board surface coating | coated part 7a has a structure which is hard to be compressed in the thickness direction, and the structural strength is raised.

  The first reinforcing member 7 is fixed to the panel member 6 by a plurality of blind rivets R inserted through the first plate portion 7a1. In the interior panel structure 4, as an example, the distal end head portion on the insertion side of each blind rivet R does not penetrate the first plate surface 6 e, and remains inside the panel material 6 (here, in the resin plate 6 i). The length of the blind rivet R is defined by, for example, the thickness D3 of the first plate portion 7a1, the thickness of the metal plate 6j located on the second plate surface 6f side of the panel material 6, and the thickness of the resin plate 6i. . For this reason, the blind rivet R hardly affects the surface of the first plate surface 6e.

  When the blind rivet R is provided, for example, a drill is used to define the cutting depth, and a hole (not shown) having a predetermined depth is formed on one surface (second plate surface 6f) of the panel material 6 that cannot be seen from the inside of the vehicle. Form. The depth of the hole is, for example, the depth from the metal plate 6j to the inside of the resin plate 6i. A blind rivet R is driven into this hole, and the tip head is expanded and fixed inside the resin plate 6i.

  The end surface covering portion 7b is formed continuously with the plate surface covering portion 7a. The end surface covering portion 7b is formed in a hollow column shape having a hollow inside, and is used as a door column that reinforces while covering the end surface 6g on the second side 6d side of the panel material 6. When the cross section orthogonal to the longitudinal direction of the first reinforcing member 7 is viewed, the end surface covering portion 7b extends in the thickness direction of the panel material 6 from one end of the plate surface covering portion 7a in the one direction. By extending in the direction along the first plate surface 6e, the end surface 6g of the panel material 6 and a part of the second side 6d of the first plate surface 6e are respectively covered. Between the plate surface covering portion 7a and the end surface covering portion 7b, an orthogonal corner portion 7d in which the plate surface covering portion 7a and the end surface covering portion 7b are orthogonal to each other is formed. By forming the orthogonal corner portion 7d, the structural strength of the first reinforcing member 7 at the continuous portion of the plate surface covering portion 7a and the end surface covering portion 7b is increased.

  The protruding portion 7 c protrudes from the end surface covering portion 7 b toward the interior panel structure 4 of the door pocket 2 on the other side. A handrail attaching portion 9 is fixed to each protruding portion 7 c in the vicinity of both longitudinal ends of the first reinforcing member 7.

  The 1st reinforcement material 7 consists of aluminum as an example, and is integrally formed by extrusion. Each number of the 1st board part 7a1 and the 2nd board part 7a3 is not limited, and can be adjusted suitably. If the number of each of the first plate portion 7a1 and the second plate portion 7a3 is increased, the reinforcing effect by the first reinforcing member 7 can be increased. If the number of each of the first plate portion 7a1 and the second plate portion 7a3 is reduced, the first reinforcing member 7 can be reduced in weight and simplified.

  In addition, although the width | variety of the plate surface coating | coated part 7a in the said one direction can be set suitably, for example, it can set to the range of 1/10 or more and 1/2 or less with respect to the width | variety of the panel material 6 in the said one direction. . In addition, the length of the plate surface covering portion in the longitudinal direction of the first reinforcing member 7 can also be set as appropriate. For example, the length is 60% or more and 100% or less of the length in the longitudinal (vertical) direction of the panel member 6. Can be set.

  The second reinforcing member 8 is a long plate-like member extending in a direction intersecting with the longitudinal direction of the first reinforcing member 7 (see FIG. 3). The second reinforcing material 8 is provided in the vicinity of the upper side 6a of the panel material 6 so as to sandwich the first plate surface 6e and the second plate surface 6f of the panel material 6. As shown in FIG. 5, a part of the second reinforcing member 8 is overlapped with the third plate portion 7a4 extending from the second plate portion 7a3. In the overlapped portion 16, the first reinforcing member 7 and the second reinforcing member 8 are connected by mechanical fastening with a fastening member B (a combination of a countersunk bolt B1 and a nut B2), for example. The thickness D4 of the second reinforcing member 8 in the overlapping portion 16 of the second reinforcing member 8 and the third plate portion 7a4 is the same as the thickness D3 and the distance G of the first plate portion 7a1. By setting the thickness D4 in this way, the second reinforcing material 8 is brought into surface contact with both the second plate surface 6f and the third plate portion 7a4, and the first reinforcing material 7 and the second reinforcing material 8 An overlapping portion 16 is formed for fixing the.

  The handrail attaching part 9 is fixed to the protrusion part 7c of the 1st reinforcement material 7 with fastening members, such as a screw, as an example (refer FIG. 2). The handrail 10 is a long member formed by bending a metal pipe, and is fixed to each handrail attachment portion 9 with a fastening member such as a screw in the vicinity of both ends in the longitudinal direction.

  The mounting bracket 11 is a bracket for mounting the finger protection member 12. The mounting bracket 11 extends in the longitudinal direction of the first reinforcing member 7 and is disposed between the end surface covering portion 7b and the protruding portion 7c. For example, the mounting bracket 11 is fixed to the protruding portion 7c by a fastening member such as a screw. The finger protection member 12 is made of, for example, an elastic member such as rubber, and extends in the longitudinal direction of the first reinforcing member 7 in the same manner as the mounting bracket 11. As an example, the finger protection member 12 is fixed to the mounting bracket 11 with an adhesive or the like.

  The structure attachment portion 13 is formed by bending a sheet metal member, and is used as a fixing portion for attaching the interior panel structure 4 to the railway vehicle structure 14 (see FIG. 1). The structure attachment portion 13 extends upward from a portion close to the end face 6g of the upper side 6a of the panel material 6. As an example, the structure attachment portion 13 is fixed to the second reinforcing member 8 by a fastening member such as a screw or a rivet. Moreover, the structure attachment part 13 is fixed to the railway vehicle structure 14 by, for example, a fastening member such as a screw or a rivet.

  In the interior panel structure 4, the plate surface covering portion 7 a of the first reinforcing member 7 is connected to the first plate portion 7 a 1 in surface contact with the second plate surface 6 f of the panel material 6 and the first plate portion 7 a 1, and the panel material The second plate portion 6a3 facing the second plate surface 6f with a gap extends in the longitudinal direction and is alternately arranged in the one direction. Thereby, in the part where 2nd board part 7a3 and 2nd board surface 6f of interior panel structure 4 oppose, a hollow structure is formed by panel material 6 and 1st reinforcement material 7 (refer to Drawing 4), and panel material 6 is firmly reinforced by the first reinforcing member 7. Therefore, for example, it is possible to reinforce the panel material 6 so as to prevent the panel material 6 from being bent and bent in the longitudinal (vertical) direction. Moreover, since the 1st reinforcement material 7 has high structural intensity | strength by forming the continuous part in which the plate surface coating | coated part 7a and the end surface coating | coated part 7b are integrated continuously, The vicinity of the end face 6g can be strongly reinforced.

  In addition, the first reinforcing member 7 is provided in a partial region of the second plate surface 6f of the panel member 6 along the second side 6d of the panel member 6 that is separated from the railcar structure 14, and the panel member 6 By providing the second reinforcing material 8 along the upper side 6 a, it is possible to appropriately reinforce the portion of the panel material 6 that needs to be reinforced with the first reinforcing material 7 and the second reinforcing material 8. Therefore, in order to reinforce the panel material 6, it is not necessary to increase the overall thickness of the panel material 6, and the excessive thickness of the panel material 6 can be reduced. Therefore, the panel material 6 can be reduced in weight and thickness. Thereby, since the selection range of the member which can be utilized as the panel material 6 can be expanded, the cost of the panel material 6 can be reduced using the member marketed, for example. Furthermore, the thickness D3 of the 1st board part 7a1 of the 1st reinforcement material 7 can be made thinner than the thickness D2 of the 2nd board part 7a3, and the weight reduction and thickness reduction of the 1st reinforcement material 7 can be achieved. Therefore, in the interior panel structure 4, the interior panel structure 4 can be reduced in weight and thickness while the panel material 6 is firmly reinforced by the first reinforcing material 7 and the second reinforcing material 8.

  Further, by forming the first reinforcing material 7 thin, the panel material 6 can be reinforced with the first reinforcing material 7 even when the separation distance between the sliding doors 3 and the panel material 6 cannot be made so large. Since the first plate portion 7a1 is in surface contact with the second plate surface 6f of the panel material 6, when the total thickness of the first plate portion 7a1 and the panel material 6 can be secured to some extent, the first plate portion 7a1 Even if the thickness D3 is slightly reduced, it is considered that the interior panel structure 4 is unlikely to have insufficient strength.

  Further, the first reinforcing member 7 has a high structural structure because the plate surface covering portion 7a and the end surface covering portion 7b are integrally formed, and the continuous portion of the plate surface covering portion 7a and the end surface covering portion 7b is formed. Has strength. Specifically, in the first reinforcing member 7, the plate surface covering portion 7a and the end surface covering portion 7b are integrally formed, and the plate surface covering portion 7a and the end surface covering portion 7b are orthogonal to each other at the orthogonal angle portion 7d. Therefore, the first reinforcing member 7 is unlikely to buckle in both the longitudinal direction and the short direction. For this reason, the end surface 6g of the panel material 6 and its vicinity region can be firmly reinforced with the first reinforcing material 7.

  In the interior panel structure 4, the second reinforcing material 8 is provided so as to extend in a direction intersecting with the longitudinal direction of the first reinforcing material 7 (horizontal direction in the present embodiment). It can also be reinforced to prevent bending and bowing.

  Moreover, since the 1st reinforcement material 7 has a simple structure with which the plate surface coating | coated part 7a, the end surface coating | coated part 7b, and the protrusion part 7c were integrated, it can manufacture easily. Thus, by integrating the plate surface covering portion 7a, the end surface covering portion 7b, and the protruding portion 7c of the first reinforcing member 7, the number of components of the interior panel structure 4 is reduced, and the interior panel structure 4 is reduced. Can be manufactured efficiently.

  Moreover, when forming the 1st reinforcement material 7 integrally by an extrusion process or a forge process, the 1st reinforcement material 7 can be formed more easily than the case where a reinforcement material is comprised with the frame which welded the several member, for example. Further, in this case, it is possible to eliminate the trouble of correcting the welding distortion and the like after forming the frame. Further, the first reinforcing member 7 can be easily fixed to the panel member 6 using a fastening member such as a blind rivet R.

  In addition, in the conventional door pocket structure of a railway vehicle, the panel material is generally reinforced by using a reinforcing material formed by welding a plurality of aggregates by welding. There are many cases where welding distortion occurs in the material, and there is a burden that it takes a lot of time to remove the welding distortion when manufacturing the interior panel structure. On the other hand, in this embodiment, since the 1st reinforcement material 7 and the 2nd reinforcement material 8 are connected by the mechanical fastening by the fastening member B, it welds to the connection part of the 1st reinforcement material 7 and the 2nd reinforcement material 8. No distortion occurs. Further, since the first reinforcing member 7 and the second reinforcing member 8 are fixed to the panel member 6 by mechanical fastening with the blind rivet R, each fixing of the first reinforcing member 7 and the second reinforcing member 8 to the panel member 6 is performed. Weld distortion does not occur in the part. Thereby, the welding distortion removal operation | work at the time of manufacturing the interior panel structure 4 can be made unnecessary.

  In addition, since the distance G between the second plate portion 7a3 of the first reinforcing member 7 and the second plate surface 6f of the panel member 6 and the thickness D4 of the second reinforcing member 8 are the same, for example, Since the 1 reinforcing material 7 is combined with the second reinforcing material 8, it is possible to reduce the processing range and the processing amount when cutting. In addition, since the distance G between the second plate portion 7a3 of the first reinforcing member 7 and the second plate surface 6f of the panel member 6 and the thickness D4 of the second reinforcing member 8 are the same, the first reinforcing member is provided. As the flat bolt B1 and the blind rivet R used for fixing the material 7 and the second reinforcing material 8 and fixing the first reinforcing material 7 and the second reinforcing material 8 to the panel material 6, respectively, The same type can be used and work efficiency can be improved. Further, by configuring the panel material 6 with a highly rigid composite panel material, the number of reinforcing materials for reinforcing the panel material 6 can be reduced.

  In the interior panel structure 4, the handrail 10 is configured separately from the component parts such as the first reinforcing member 7 and the second reinforcing member 8, and the degree of freedom in design is increased. For this reason, for example, the handrail 10 can be designed such that its cross-sectional shape changes in the longitudinal direction. In addition, the handrail 10 can be designed such that the lower end of the handrail 10 is located at a certain height from the foot of the passenger, so that the leg of the passenger can be prevented from hitting the handrail 10 in the vicinity of the entrance / exit. Further, by configuring the handrail 10 with a material such as stainless steel, the strength can be improved and the surface can be kept clean.

  Hereinafter, another embodiment of the present invention will be described focusing on differences from the first embodiment.

(Second Embodiment)
FIG. 6 is a cross-sectional view of the interior panel structure 40 according to the second embodiment. The first reinforcing member 17 includes a first plate portion 17a1 and a second plate portion 17a3 in which the plate surfaces are arranged to face each other with a space therebetween. Further, the first reinforcing member 17 has a plurality of connecting portions 17a2 arranged in parallel in the first direction so as to connect the first plate portion 17a1 and the second plate portion 17a3 in the facing direction. A space S surrounded by two adjacent connecting portions 17a2, the first plate portion 17a1 and the second plate portion 17a3 is formed inside the first reinforcing member 17. Thereby, the 1st reinforcement material 17 has a hollow structure because the cross section orthogonal to the longitudinal direction is formed in hollow shape. The first reinforcing member 17 is fixed to the panel member 6 by a blind rivet R provided so as to pass through the connecting portion 17a2.

  Since the first reinforcing member 17 is formed to have a hollow structure and has high structural strength, the first reinforcing member 17 deforms like a bow in the longitudinal (vertical) direction and is not easily bent, and also in the thickness direction. Difficult to deform. Therefore, the panel material 6 can be reinforced more strongly by reinforcing the panel material 6 using the first reinforcing material 17 having such a hollow structure.
