  By the way, in order to realize the structure of the outer plate, the first reinforcing member, and the second reinforcing member as described above, the height of one flange portion and the other flange portion of the second reinforcing member is set. The difference needs to match the height of the top of the first reinforcing member. In particular, when the joining of each member is realized by laser welding, the gap between the members needs to be suppressed to about 1/10 or less of the plate thickness in order to form a sound welded portion.

  However, since both the first reinforcing member and the second reinforcing member are usually formed by pressing, dimensional variations are likely to occur, and there is a tendency between one flange portion and the other flange portion in the second reinforcing member. It was difficult to make the height difference coincide with the height of the top of the first reinforcing member.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vehicle panel structure that can realize a reinforcing structure of an end portion of an outer plate even when there are variations in the dimensions of the reinforcing member.

  In order to solve the above-described problems, a vehicle panel structure according to the present invention includes an outer plate serving as an outer wall of a railway vehicle, a first reinforcing member having a cross-sectional hat shape arranged side by side on the inner surface of the outer plate, and an outer plate. 2nd which is arrange | positioned in the direction which cross | intersects the 1st reinforcement member in an edge part, has one flange part joined to the top part of the 1st reinforcement member, and the other flange part joined to the inner surface of an outer plate | board. The second reinforcing member includes a first split member including one flange portion and a first adjustment piece projecting in a height direction of the top portion of the first reinforcing member; A second split member including the other flange portion and a second adjustment piece that protrudes in the height direction of the top of the first reinforcing member and abuts on the first adjustment piece; The split member and the second split member are integrated by joining the first adjustment piece and the second adjustment piece. It is characterized in.

  In the vehicle panel structure, one flange portion of the second reinforcing member is joined to the top portion of the first reinforcing member at the end portion of the outer plate, and the other flange portion is joined to the inner surface of the outer plate. By joining the second reinforcing member as described above, the rigidity of the end portion of the outer plate is sufficiently ensured. In the vehicle panel structure, the second reinforcing member is divided into a first divided member and a second divided member. The first divided member and the second divided member have a first adjustment piece and a second adjustment piece that protrude in the height direction of the top portion of the first reinforcing member, and are brought into contact with each other. The first adjustment piece and the second adjustment piece are integrated together.

  According to such a configuration of the second reinforcing member, the position of the first divided member and the position of the second divided member are within a range where the first adjusting piece and the second adjusting piece can come into contact with each other. The height of the top of the first reinforcing member can be adjusted. Accordingly, even if the first reinforcing member and the second reinforcing member have dimensional variations, the height difference between the one flange portion and the other flange portion of the second reinforcing member is determined as the top portion of the first reinforcing member. The above-described reinforcing structure of the end portion of the outer plate can be easily realized.

  Moreover, it has the opposing part which opposes at least an edge part of an outer plate, and it exists in the longitudinal direction of a 1st reinforcement member by the edge part of an outer plate | board, an opposing part, and the web part of an adjacent 1st reinforcement member. A plate-like member joined to the top of the first reinforcing member so as to form a hollow portion is further provided, and one flange portion is joined to the top of the first reinforcing member via the plate-like member. It is preferable. In this case, the rigidity of the end portion of the outer plate can be further increased by the hollow portion. In addition, since this configuration can be realized with a simple configuration in which a plate-like member is added, an increase in the number of parts and an increase in weight can be suppressed.

  Moreover, it is preferable that the 2nd reinforcement member has comprised the cross-sectional hat shape. In this case, the rigidity of the end portion of the outer plate is further enhanced by the channel portion of the second reinforcing member, and when combined with the plate-like member, the second portion is provided by the plate-like member and the channel portion of the second reinforcing member. A hollow portion is formed in the longitudinal direction of the reinforcing member. Thereby, since the cross structure of a hollow part is formed in the outer-plate edge part, the further improvement of rigidity is achieved.

  Moreover, it is preferable that joining of one flange part and the top part of the 1st reinforcement member, and joining of the other flange part and the inner surface of an outer plate are made | formed by laser welding. The gap between the members is suppressed to a level sufficient for laser welding by adjusting the position of the first divided member and the position of the second divided member in the height direction of the top of the first reinforcing member. be able to. In laser welding, the amount of heat input to the member can be suppressed, so that it is possible to realize a strong joint that suppresses deformation of the member.

  According to the present invention, it is possible to realize the reinforcing structure of the end portion of the outer plate even if the dimensional variation of the reinforcing member is present.

  Hereinafter, a preferred embodiment of a vehicle panel structure according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing an embodiment of a railway vehicle structure to which a vehicle panel structure according to the present invention is applied. As shown in the figure, the railway vehicle structure 1 includes a floor structure 2, a side structure 3, a roof structure 4, and a wife structure 5, and these structures are joined to each other, thereby It has a box shape with a space to accommodate it inside.

  The floor structure 2 is disposed at the bottom of the railway vehicle structure 1 as a structure constituting the floor of the vehicle. The side structure 3 and the wife structure 5 are erected on the left and right edges and the front and rear edges of the floor structure 2 as structures constituting the side part of the vehicle. The side structure 3 is provided with a plurality of door portions 6 (for example, three locations) at equal intervals for passengers / occupants to get on and off.

  In addition, window portions 7 are provided between the door portions 6 and 6 and at both ends of the side structure 3. The wife structure 5 is provided with an entrance / exit 8 for an occupant / passenger to move between vehicles. The roof structure 4 is arranged as a structure that forms the roof portion of the vehicle. An air conditioner and a pantograph for adjusting the temperature inside the vehicle are installed on the upper part of the roof structure 4.

  Next, the configuration of the vehicle panel structure applied to the side structure 3 will be described in more detail. FIG. 2 is a perspective view showing the configuration of the vehicle panel structure according to the first embodiment. FIG. 3 is an exploded perspective view thereof. In the figure, only one end of the vehicle panel structure is shown, but the other end also has the same configuration.

  As shown in FIGS. 2 and 3, the vehicle panel structure 10 includes an outer plate 20, a first reinforcing member 30, and a second reinforcing member 40. The outer plate 20 is a member constituting the outer wall of the vehicle. The outer plate 20 is made of stainless steel (SUS301L) having a thickness of about 1.2 mm, for example, and has a rectangular shape with a length of about 940 mm.

  The first reinforcing member 30 includes a rectangular top portion 31, web portions 32 and 32 erected from both sides in the width direction of the top portion 31, and flange portions 33 and 33 projecting outward from the tips of the web portions 32 and 32. A cross-sectional hat-shaped member (hat type material). The first reinforcing member 30 is made of, for example, stainless steel (SUS301L) having a thickness of 0.8 mm, and has a long shape corresponding to the length of the outer plate 20. Moreover, the width | variety of the top part 31 is about 50 mm, for example, and the height of the web part 32 is about 35 mm, for example.

  The first reinforcing member 30 is arranged in parallel in the vehicle height direction at a pitch of 200 mm, for example, with the top portion 31 facing the inside of the vehicle, and is formed in a spot shape along the flange portions 33 and 33. It is firmly joined to the inner surface of the outer plate 20 by W1. Thereby, a hollow portion is formed between the first reinforcing member 30 and the outer plate 20 along the longitudinal direction of the first reinforcing member 30.

  Similar to the first reinforcing member 30, the second reinforcing member 40 includes a rectangular top portion 41, web portions 42 and 42 erected from both sides in the width direction of the top portion 41, and tips of the web portions 42 and 42. It is a cross-sectional hat-shaped member (hat type | mold material) which has the flange parts 43 and 43 which protrude outside from. Moreover, the width | variety of the top part 41 is about 50 mm, for example.

  On the other hand, in the second reinforcing member 40, as shown in FIG. 4, the heights of the web portions 42 and 42 are different from each other, and the height of one web portion 42 is about 35 mm, for example. The height is about 70 mm, for example. As a result, the difference between the height of one flange portion 43 and the height of the other flange portion 43 in the second reinforcing member 40 is 35 mm, which matches the height of the top portion 31 of the first reinforcing member 30. It is like that.

  The second reinforcing member 40 is disposed at the end 20a of the outer plate 20 so as to be orthogonal to the first reinforcing member 30 so that the top 41 faces the inside of the vehicle. The second reinforcing member 40 includes a flange portion 43 in a state where one flange portion 43 is in contact with the top portion 31 of the first reinforcing member 30 and the other flange portion 43 is in contact with the inner surface of the outer plate 20. It is firmly joined to the outer plate 20 and the first reinforcing member 30 by a laser welded portion W2 formed in a spot shape along 43,43.

  Further, the end portion 30 a of the first reinforcing member 30 is in contact with the inner side surface of the other web portion 42 of the second reinforcing member 40. The other web part 42 and the end part 30a of the first reinforcing member 30 are firmly joined to each other by a spot-like laser welding part W3.

  As described above, in the vehicle panel structure 10, the second reinforcing member 40 is disposed in the end portion 20 a of the outer plate 20 in a direction orthogonal to the first reinforcing member 30, and one of the second reinforcing members 40 is arranged. The flange portion 43 is joined to the top portion 31 of the first reinforcing member 30, and the other flange portion 43 is joined to the inner surface of the outer plate 20. By joining the second reinforcing member 40 as described above, the rigidity of the end portion 20a of the outer plate 20 is sufficiently ensured. Moreover, since the amount of heat input to the member can be suppressed by using laser welding for joining each member, it is possible to realize strong joining with suppressing deformation of the member.

  By the way, in realizing the reinforcing structure of the end portion 20a of the outer plate 20 described above, the difference in height between one flange portion 43 and the other flange portion 43 in the second reinforcing member 40 is determined as the first reinforcing member. It is necessary to match the height of the top 31 of 30. In this embodiment, since laser welding is used for joining the one flange portion 43 and the top portion 31 and joining the other flange portion 43 and the outer plate 20, in order to form a sound welded portion, It is required that the gap between the members be suppressed to about 1/10 or less of the plate thickness.

  However, since both the first reinforcing member 30 and the second reinforcing member 40 are normally formed by pressing, there is a problem that dimensional variations are likely to occur. Therefore, when the second reinforcing member 40 is disposed at the end 20a of the outer plate 20, the height difference between the one flange portion 43 and the other flange portion 43 in the second reinforcing member 40 is the first difference. In some cases, the height of the top portion 31 of the reinforcing member 30 does not match the height, and the gap between the members cannot always satisfy the conditions required for laser welding.

  On the other hand, the second reinforcing member 40 described above is divided into two in the width direction at the top 41 by a first dividing member 51 and a second dividing member 52, as shown in FIG. The first split member 51 includes one flange portion 43, one web portion 42, a half portion 41a on one side of the top portion 41, and a first adjustment piece 53 formed at the tip of the half portion 41a. Have. The first adjustment piece 53 extends in the longitudinal direction of the first split member 51 and projects in the direction opposite to the web portion 42 along the height direction of the top portion 31 of the first reinforcing member 30. .

  The second split member 52 includes the other flange portion 43, the other web portion 42, the half portion 41b on the other side of the top portion 41, and the second adjustment piece 54 formed at the tip of the half portion 41b. Have. The second adjustment piece 54 extends in the longitudinal direction of the second split member 52, and projects in the same direction as the first adjustment piece 53 along the height direction of the top of the first reinforcing member 30. ing.

  The first dividing member 51 and the second dividing member 52 are in a state where the first adjusting piece 53 and the second adjusting piece 54 are in contact with each other, and the first adjusting piece 53 and the second adjusting member 54 are in contact with each other. The adjustment pieces 54 are firmly joined to each other by laser welding portions W4 formed in a spot shape along the longitudinal direction.

  According to the configuration of the second reinforcing member 40 as described above, the position of the first split member 51 and the second split member are within a range in which the first adjusting piece 53 and the second adjusting piece 54 can come into contact with each other. The position 52 can be adjusted in the height direction of the top 31 of the first reinforcing member 30. For example, as shown in FIG. 5A, the position of the first divided member 51 with respect to the second divided member 52 is set to the second position while the first adjusting piece 53 and the second adjusting piece 54 are kept in contact with each other. By shifting to the base end side of the adjusting piece 54, the difference in height between the one flange portion 43 and the other flange portion 43 in the second reinforcing member 40 can be reduced.

  For example, as shown in FIG. 5B, the position of the first split member 51 relative to the second split member 52 is maintained while the first adjustment piece 53 and the second adjustment piece 54 are kept in contact with each other. By shifting to the tip side of the second adjustment piece 54, the difference in height between the one flange portion 43 and the other flange portion 43 in the second reinforcing member 40 can be increased.

  Therefore, even if the first reinforcing member 30 and the second reinforcing member 40 have dimensional variations, the difference in height between one flange portion 43 and the other flange portion 43 in the second reinforcing member 40 is the first difference. Therefore, the reinforcing structure of the end portion 20a of the outer plate 20 can be easily realized.

  Subsequently, a second embodiment of the present invention will be described. FIG. 6 is a perspective view showing a configuration of a vehicle panel structure according to the second embodiment. FIG. 7 is an exploded perspective view thereof.

  As shown in FIGS. 6 and 7, the vehicle panel structure 60 according to the second embodiment has a plate-like member 70 interposed between the first reinforcing member 30 and the second reinforcing member 40. This is different from the first embodiment. The plate-like member 70 is made of, for example, stainless steel (SUS301L) having a thickness of about 0.8 mm. The plate-like member 70 has a substantially rectangular main body 71 and a plurality of projecting portions 72 that project from one side of the main body 71 at a pitch of 200 mm, for example.

  In the plate-like member 70, the main body portion 71 faces the end portion 20 a of the outer plate 20 (hereinafter, the main body portion 71 is referred to as a facing portion 73), and each of the projecting portions 72 is the first reinforcing member 30. It arrange | positions so that it may contact | abut on the top part 31, and is firmly joined to the top part 31 of the 1st reinforcement member 30 by the laser welding part W5 formed in the spot part at the opposing part 73 and the overhang | projection part 72. FIG. In addition, the length of the overhang | projection part 72 is about 100 mm-200 mm, for example. Moreover, the corner part which the opposing part 73 and the overhang | projection part 72 make is processed into the concave shape of (phi) 30 mm, for example.

  In the vehicle panel structure 60, the second reinforcing member 40 is in a state where one flange portion 43 is in contact with the plate-like member 70 and the other flange portion 43 is in contact with the inner surface of the outer plate 20. ing. The second reinforcing member 40 is firmly joined to the outer plate 20, the first reinforcing member 30, and the plate-like member 70 by the laser welded portion W <b> 2 formed in a spot shape along the flange portions 43 and 43. Has been.

  For such a vehicle panel structure 60, the same operational effects as those of the first embodiment can be obtained. That is, even if the first reinforcing member 30 and the second reinforcing member 40 have dimensional variations, the difference in height between the one flange portion 43 and the other flange portion 43 in the second reinforcing member 40 is the first difference. Therefore, the reinforcing structure of the end portion 20a of the outer plate 20 can be easily realized.

  Further, in the vehicle panel structure 60, the end 20a of the outer plate 20 is joined by joining the outer plate 20, the first reinforcing member 30, the second reinforcing member 40, and the plate-like member 70, as shown in FIG. The first hollow portion S <b> 1 extending in the longitudinal direction of the first reinforcing member 30 is formed by the facing portion 73 of the plate-like member 70 and the web portions 32, 32 of the adjacent first reinforcing member 30. Yes.

  Furthermore, in the vehicle panel structure 60, the second reinforcing member 40 is joined by joining the outer plate 20, the first reinforcing member 30, the second reinforcing member 40, and the plate-like member 70, as shown in FIG. A second hollow portion S2 is formed in a direction orthogonal to the first hollow portion S1 by the top portion 41, the web portions 42 and 42, and the facing portion 73 of the plate-like member 70. The second hollow portion S2 is partitioned by the facing portion 73, and thereby three-dimensionally intersects without communicating with the first hollow portion S1.

  With such an intersecting structure of the first hollow portion S1 and the second hollow portion S2, in the vehicle panel structure 60, the rigidity of the end portion 20a of the outer plate 20 can be further increased. Compared with the conventional configuration in which the bone members are arranged in the crossing direction, this configuration can be realized only by adding the plate-like member 70, so that an increase in the number of parts can be avoided and an increase in weight can be suppressed.

  The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the other flange portion 43 of the second reinforcing member 40 is directly joined to the inner surface of the outer plate 20. However, like the vehicle panel structure 80 shown in FIG. The side edge 82 of the door frame 81 may be sandwiched between the outer flange 20 and the other flange 43, and the outer plate 20, the flange 43, and the side edge 82 may be integrally joined by the laser welding portion W2.

  In the above-described embodiment, the first adjustment piece 53 of the first division member 51 and the second adjustment piece 54 of the second division member 52 both project in the direction opposite to the web portion 32. However, the first adjustment piece 53 and the second adjustment piece 54 only need to protrude along the height direction of the top portion of the first reinforcing member 30, and may protrude toward the web portion 32 side. Good.

  Furthermore, for example, like the vehicle panel structure 90 shown in FIG. 11, the second reinforcing member 40 may be divided at the other web portion 42 instead of the top portion 41. In this case, the tip end portion of the other web portion 42a in the first split member 91 becomes the first adjustment piece 93, and the tip portion of the other web portion 42b in the second split member 92 becomes the second adjustment piece 94. Become. Therefore, similarly to the above-described embodiment, the first adjustment piece 93 and the second adjustment piece 94 are brought into contact with each other, and are spot-like along the longitudinal direction of the first adjustment piece 93 and the second adjustment piece 94. What is necessary is just to join the 1st division member 91 and the 2nd division member 92 by the laser welding part W5 formed in this.
