  Embodiment 1 of the present invention will be described below with reference to FIGS. This embodiment shows an example applied to a stationary fuel cell system. FIG. 1 shows a state before the side member 4 is attached to the case body 1 of the fuel cell case. FIG. 2 shows a state in which the lower side portion 4 d of the side member 4 is placed on the first engaging portion 6 of the case body 1. 3 shows a state in which the lower side portion 4d of the side surface member 4 is placed on the first engaging portion 6 of the case body 1, and the side surface member 4 is moved in the direction of the arrow D3 with the lower side portion 4d of the side surface member 4 as the oscillation center region. A state in which the second engaging portion 7 is brought into contact with the case main body 1 by being swung in the attachment direction is shown. FIG. 4 shows a state in which the side member 4 is attached to the case main body 1.

  As shown in FIG. 1, the fuel cell case according to the present embodiment includes a metal case body 1 having a substantially square box shape and a metal or hard resin side member having a square plate-like panel shape. 4 is provided. The case body 1 includes a first side surface 11 that is a front surface, a second side surface 12 that is a back surface, and a third side surface 13 and a fourth side surface 14 that face each other. The first side surface 11 has a maintenance opening 15 that is closed by the side member 4, and a mounting surface 16 that is formed at the peripheral edge of the opening 15.

  In FIG. 1, an arrow W direction indicates a direction along the left-right direction in which the surface 4 a of the side member 4 is extended. The arrow H direction indicates the height direction of the case body 1 and the side member 4. An arrow D direction indicates a depth direction of the case body 1.

  According to the present embodiment, a method of attaching the side member 4 to the case main body 1 as a kind of lid is adopted by bringing the side member 4 close to the case main body 1 along the arrow D3 direction, that is, the depth direction of the case main body 1. Has been. Therefore, the side member 4 is neither a sliding door system nor a double door system. With such a system, the installation area of the fuel cell case can be reduced, and the open area of the opening 15 can be increased, which is advantageous for maintenance. As shown in FIG. 1, the opening 15 has an opening amount close to almost the entire front surface of the case body 1.

  The side member 4 is a front panel of the fuel cell case, and is a panel that is detachably attached to the mounting surface 16 on the side surface 11 side that is the front surface of the case body 1. The side member 4 has a substantially square shape, and includes an upper side 4u, a lower side 4d, two side sides 4s, and a vent 4x penetrating in the thickness direction. The height of the side member 4 substantially corresponds to the height of the case body 1. The width of the side member 4 substantially corresponds to the width of the case body 1. The width means a dimension in a direction along the arrow W direction. Specifically, the height of the side member 4 is 50 centimeters or more or 80 centimeters or more. The width of the side member 4 is 50 centimeters or more or 80 centimeters or more. Although such a side member 4 is reduced in weight, the handling work is not easy with few workers.

  As shown in FIG. 1, the side part 4 s of the side member 4 is bent in an arc shape toward the case body 1. At the lower part of the side part 4 s of the side member 4, an ear-shaped attachment collar part 40 extending from the side part 4 s along the arrow D direction is formed. A first bolt insertion hole 41 is formed in the mounting flange 40. The first bolt insertion hole 41 has an axis along the arrow W direction. As shown in FIG. 1, a first attachment hole 17 is formed in the lower part of the third side surface 13 and the fourth side surface 14 of the case body 1. The axis of the first mounting hole 17 is substantially parallel to the axis of the first bolt insertion hole 41 and extends along the arrow W direction.

  Further, as shown in FIG. 1, a second bolt insertion hole 42 is formed on the side of the side member 4 that faces the upper side 1 u of the case body 1. The axis of the second bolt insertion hole 42 is along a direction substantially parallel to the arrow D direction. As shown in FIG. 1, a second attachment hole 18 is formed on the upper side 1 u side of the case body 1. The axis of the second mounting hole 18 is substantially parallel to the axis of the second bolt insertion hole 42 and extends along the arrow D direction.

  Here, when the side member 4 is attached to the case body 1, the first bolt insertion hole 41 and the first attachment hole 17 are set to face each other so that the first attachment bolt 31 can be inserted. And the 2nd bolt insertion hole 42 and the 2nd attachment hole 18 are set so that it may mutually face so that the 2nd attachment bolt 32 can be inserted. As can be understood from FIG. 1, the first attachment bolt 31 is attached to the first attachment hole 17 along the locus P <b> 1. The second attachment bolt 32 is attached to the second attachment hole 18 along the locus P2. According to this embodiment, a plate-like insulator material 8 (inner layer member) is attached to the inner surface 4 i of the side member 4. The insulator material 8 also serves for sound insulation, vibration reduction, heat insulation, and the like, and is formed of a material softer than the material of the side member 4 (for example, a resin foam such as urethane foam).

  As shown in FIGS. 1 to 3, the engaging portion 5 is for temporarily determining the position of the side member 4, and includes a first engaging portion 6 provided on the case body 1 and an upper side of the side member 4. And a second engaging portion 7 provided on the head. As shown in FIG. 2, the first engagement portion 6 is provided on the bottom side of the case body 1. The first engaging portion 6 also functions as a leg portion of the case body 1. In attaching the side member 4 to the attachment surface 16 of the case main body 1, the first engaging portion 6 places the lower side portion 4 d of the side member 4 on the case main body 1 to be engaged with each other in the gravity direction (G direction). It has a function of temporarily determining the position of the side member 4.

  As shown in FIGS. 1 and 3, the first engaging portion 6 is installed on the floor surface FA and protrudes in the protruding direction (arrow A <b> 1 direction) toward the side member 4. The 1st engaging part 6 has the inclined surface 64 which inclines so that height may become low as it goes to a front-end | tip, and the 1st mounting surface 65 along horizontal. The first engagement portion 6 includes a first placement surface 65 for placing the lower side portion 4 d of the side member 4. When the position of the side member 4 in the gravitational direction is temporarily determined with respect to the case body 1, the first placement surface 65 of the first engagement portion 6 is a portion on which the lower side portion 4 d of the side member 4 is placed. As shown in FIG. 1, the first engaging portion 6 includes a frame portion 60 in which a hard plate such as a metal plate is formed in a frame shape, and a soft loading material such as urethane rubber loaded in the frame portion 60. And a loading section 61 formed by loading. The loading unit 61 contributes to vibration damping.

  As shown in FIG. 2, the second engagement portion 7 protrudes from the upper side portion 4 u of the side member 4 toward the case body 1. When the position of the side member 4 is tentatively determined, the second engaging portion 7 has a function of being placed on the upper side 1 u of the case body 1 so that the side member 4 can be suspended from the case body 1. As shown in FIG. 2, the second engaging portion 7 extends in a hook shape extending in the lateral direction (in the direction of arrow D <b> 3) toward the case body 1 at the upper side portion 4 u of the side member 4. An engaging portion 72 is provided.

  The extending engagement portion 72 extends along a direction (arrow D3 direction, mounting direction of the side member 4) that intersects the direction along the surface 4a of the side member 4. The upper side 4u of the side member 4 is provided with a second bolt insertion hole 42. The second mounting bolt 32 can be inserted into the second bolt insertion hole 42. As shown in FIG. 2, the bottom plate 1 v of the case body 1 is lifted by Δh from the upper surface of the first engaging portion 6, and water penetration is suppressed.

  Next, an operation for attaching the side member 4 to the case body 1 will be described. First, the operator manually supports the side member 4, and as shown in FIG. 2, the lower side portion 4 d of the side member 4 is flat with the plurality of (two) first engaging portions 6 of the case body 1. The first mounting surface 65 is placed. By this work, basic positioning of the side member 4 in the gravity direction is performed. Here, the height positions of the flat first mounting surfaces 65 of the plurality of (two) first engaging portions 6 are set to be the same. Therefore, if necessary, the operator slides the side member 4 in the left-right direction (the direction of the arrow W shown in FIG. 1) while the side member 4 is placed on the first engaging portion 6. The lateral position of the side member 4 can be adjusted. This operation is also easy because it can be performed while the lower side portion 4d of the side member 4 is placed on the first engaging portion 6. In addition, a plurality of first engaging portions 6 are provided and are not continuous along the direction in which the lower side portion 4 d of the side member 4 extends, and the lower side portion 4 d of the side member 4 and the first engaging portion 6 are not connected. Since the contact area is reduced, the frictional resistance in the slide movement is reduced.

  In this case, as shown in FIG. 2, the lower side portion 4 d of the side member 4 is brought close to the case body 1, and the extended engagement portion 72 of the second engagement portion 7 is separated from the case body 1. It is preferable to incline the member 4. This is to avoid interference and collision between the extended engagement portion 72 and the case body 1.

  As shown in FIG. 2, the lower side 4d of the side member 4 has an L shape in cross section. For this reason, since the contact area in the lower side part 4d increases, a pressure receiving area becomes small. In this case, the load applied to the lower side portion 4d of the side member 4 and the load applied to the first engagement portion 6 are reduced. In particular, the intersection area 403 of the plate portion 401 and the plate portion 402 constituting the lower side portion 4d of the side member 4 is rounded. If such an intersection area 403 becomes the swing center area of the side member 4, the swingability of the side member 4 is ensured.

  In some cases, when the lower side portion 4d of the side member 4 is placed on the first placement surface 65 of the first engagement portion 6 of the case body 1, the extension of the second engagement portion 7 of the side member 4 is increased. The installation engaging portion 72 may be brought into contact with the upper side portion 1u of the case main body 1.

  Here, as shown in FIG. 2, a lower flange 112 extending upward in the vertical direction is integrally formed on the lower side 1 d of the case body 1. An upper flange 110 that extends downward in the vertical direction is integrally formed on the upper side 1 u of the case body 1.

  Next, with the lower side portion 4d of the side member 4 placed on the first engaging portion 6 as a swing fulcrum region, the side member 4 faces the case body 1 in the direction of arrow D3 (attachment direction), The operator swings manually. That is, the extended engaging portion 72 of the side member 4 approaches the upper side 1u of the case body 1 so that the tilt angle θ (see FIG. 2) of the side member 4 is reduced. Thereby, the side member 4 becomes a direction along the vertical direction further.

  As a result, as shown in FIG. 4, the extended engagement portion 72 of the second engagement portion 7 of the side member 4 rides on the upper surface of the upper side portion 1 u of the case body 1. As a result, the second engaging portion 7 of the side member 4 engages while being placed on the upper side 1 u of the case body 1. In this state, even before the second mounting bolt 32 is fastened, the frictional engagement between the extended engagement portion 72 of the second engagement portion 7 of the side member 4 and the upper side portion 1u of the case body 1 is achieved. As a result, the side member 4 is prevented from falling. Therefore, the operator's work becomes easier.

  Before the lower side portion 4 d of the side member 4 is placed on the first engaging portion 6 of the case body 1, the extended engaging portion 72 of the second engaging portion 7 of the side member 4 is placed on the upper side of the case body 1. It is also conceivable to place and engage the part 1u. However, in this case, there is a possibility that the operator will not be able to visually recognize the lower side portion 4d of the side member 4.

  According to the present embodiment, as shown in FIG. 4, the extended engagement portion 72 of the second engagement portion 7 of the side member 4 is sufficiently on the upper surface of the upper side 1 u of the case body 1. As shown in FIG. 4, the lower surface of the lower side portion 4 d of the side member 4 is lifted by a gap 66 from the first placement surface 65 of the first engagement portion 6. For this reason, the lower surface of the lower side portion 4 d of the side member 4 is not in contact with the first placement surface 65 of the first engagement portion 6. Therefore, even if water droplets are present on the first placement surface 65 of the first engagement portion 6, the water droplets are less likely to contact the lower side portion 4 d of the side member 4.

  As described above, the extended engagement portion 72 of the second engagement portion 7 of the side member 4 rides on the upper side 1 u of the case body 1 and is placed on the upper side 1 u of the case body 1. In this case, as shown in FIG. 4, the second mounting hole 18 is formed in the upper flange 110 of the upper side 1 u of the case body 1. The second mounting hole 18 faces and communicates with the second bolt insertion hole 42 of the side member 4. In this state, the second mounting bolt 32 inserted into the second bolt insertion hole 42 is screwed into the second mounting hole 18 of the case body 1 and fastened.

  When the side member 4 is fitted to the case body 1 as described above, as can be understood from FIG. 1, the first mounting hole 17 of the case body 1 and the first bolt insertion hole 41 of the side member 4 have a locus P1. Face each other. In this state, the first mounting bolt 31 inserted into the first bolt insertion hole 41 is screwed into the first mounting hole 17 and attached. As can be understood from FIG. 1, the first mounting bolt 31 is mounted not from the front of the fuel cell case but from the lateral direction. For this reason, it is difficult for a viewer who exists in front of the fuel cell case to visually recognize the head portion 31 h of the first mounting bolt 31. As a result, the appearance design is improved.

  Further, when the side member 4 is attached to the case body 1 as described above, a top plate 9 is used as shown in FIG. The top plate 9 has a top plate flange 90 oriented downward in the vertical direction. The top plate 9 is fitted and attached to the case body 1 from above. As a result, the top flange 90 of the top plate 9 covers the head portion 32h of the second mounting bolt 32 from the outside. For this reason, the head portion 32h of the second mounting bolt 32 is not visually recognized from the outside. As a result, the appearance design is improved. In short, according to the present embodiment, both the first mounting bolt 31 and the second mounting bolt 32 are not visually recognized by the viewer on the front side of the fuel cell case, and the design is improved.

  When the side member 4 is attached to the case body 1 as described above, the upper surface 8u of the insulator material 8 is in close contact with the upper flange 110 on the upper side 1u side of the case body 1, as shown in FIG. Sealed. Further, when the side member 4 is attached to the case main body 1, the lower surface 8 d of the insulator material 8 is sealed in close contact with the lower flange 112 on the lower side 1 d side of the case main body 1 as shown in FIG. 8. . When sealed by the insulator material 8 in this way, external rainwater is prevented from entering the case body 1.

  As described above, when the insulator material 8 having elasticity is brought into close contact with the case body 1, the reaction force is generated. When the reaction force is increased, the side member 4 may not easily move to the case body 1 side. is there. Therefore, according to the present embodiment, before the reaction force is generated or while the reaction force is small, the extended engagement portion 72 of the second engagement portion 7 of the side member 4 is connected to the upper side of the case body 1. It is set to ride on and engage the part 1u.

  Next, the case where the side member 4 attached to the case body 1 is removed will be described. First, the operator removes the top plate 9, the first mounting bolt 31, and the second mounting bolt 32. Even when the first mounting bolt 31 and the second mounting bolt 32 are removed, the extended engaging portion 72 of the second engaging portion 7 of the side member 4 is placed on the upper side 1u of the case body 1. Therefore, the side member 4 is temporarily held on the upper side 1u of the case body 1. In this state, the extended engaging portion 72 of the second engaging portion 7 of the side member 4 is removed from the upper side 1 u of the case body 1. Then, the lower side portion 4 d of the side member 4 is placed on and supported by the first engagement portion 6. Even when the side member 4 is removed in this manner, the side member 4 can be temporarily held by the first engaging portion 6, so that the work becomes easy.

  FIG. 6A shows a state before the side member 4 is attached to the case body 1. FIG. 6B shows a state after the side member 4 is attached to the case body 1. FIG. 7A shows a state before the side member 4 is attached to the case main body 1. FIG. 7B shows a state after the side member 4 is attached to the case body 1.

  As described above, according to the present embodiment, when the side member 4 is attached to the case main body 1, the side member 4 is placed on the first engaging portion 6 of the case main body 1, thereby positioning the side member 4. You can make a temporary decision. Further, by engaging the second engaging portion 7 of the side member 4 with the upper side 1 u of the case body 1, the position of the side member 4 can be further temporarily determined. For this reason, it is reduced that an operator uses excessive effort to hold the side member 4. The operator can attach or remove the side member 4 without taking an unreasonable posture. Therefore, the worker can do it alone. Of course, the side member 4 may be attached and removed by a plurality of workers.

  FIG. 9 shows a second embodiment. The present embodiment basically has the same configuration and the same function and effect as the first embodiment. Hereinafter, a description will be given centering on portions different from the first embodiment.

  As shown in FIG. 9, the first engaging portion 6 is lifted from the floor surface FA, and can be retracted in a direction (arrow A <b> 2) in which the first engaging portion 6 is retracted to the bottom side of the case body 1. Further, the first engaging portion 6 can project in a direction projecting from the case main body 1 (arrow A1 direction). The first engaging portion 6 has a rail-shaped guide portion 6a that is concave or convex. The case body 1 has a rail-shaped guided portion 1a made of a convex or a concave. The guided portion 1 a guides the guide portion 6 a of the first engaging portion 6. Further, the case body 1 has guide portions 1c and 1d for guiding the first engagement portion 6.

  When attaching the side member 4 to the case main body 1, the operator manually projects the first engaging portion 6 in a direction (arrow A <b> 1 direction) in which the first engaging portion 6 protrudes from the case main body 1. As described above, by placing the lower side portion 4d of the side member 4 on the first engaging portion 6 of the case body 1, the position of the side member 4 in the gravitational direction is provisionally determined. If necessary, the position of the side member 4 in the left-right direction is also provisionally determined.

  Thereafter, similarly to the first embodiment, the side member 4 is fastened and fixed to the case body 1 by the second mounting bolt 32 and the first mounting bolt 31. When the work of assembling the side member 4 to the case main body 1 is completed in this way, the operator manually pushes the first engagement portion 6 and moves it in the retracting direction (in the direction of arrow A2). Evacuate. In this case, since the 1st engaging part 6 does not protrude outward from the case main body 1 and the side member 4 excessively, it is suppressed that the 1st engaging part 6 becomes obstructive.

  Further, when the side member 4 assembled to the case body 1 is removed from the case body 1, the operator pulls the retracted first engaging portion 6 to move in the protruding direction (arrow A1 direction). What is necessary is just to make it protrude outward from the case main body 1 and the side member 4. FIG. In this case, since the lower side portion 4d of the side member 4 can be temporarily held by being placed on the first engaging portion 6, the operator's work becomes easier as in the first embodiment. Note that a leg 1r that lands on the floor surface FA is provided at the bottom of the case body 1.

  FIG. 10 shows a third embodiment. The present embodiment basically has the same configuration and the same function and effect as the first embodiment. Hereinafter, a description will be given centering on portions different from the first embodiment. According to this embodiment, the first engagement portion 6 is provided, but the second engagement portion 7 is not provided.

  First, the operator manually supports the side member 4 and places the lower side portion 4d of the side member 4 on the first engaging portion 6 of the case body 1 as shown in FIG.

  Next, with the lower side portion 4d of the side member 4 placed on the first engaging portion 6 as a swing fulcrum region, the side member 4 faces the case body 1 in the direction of arrow D3 (attachment direction), The operator swings manually. Thereby, the side member 4 becomes a direction along the vertical direction. Then, the second mounting hole 18 and the second bolt insertion hole 42 are made to face each other. In this state, the second mounting bolt 32 inserted into the second bolt insertion hole 42 is screwed into the second mounting hole 18 of the case body 1 and attached. Similarly to the first embodiment, the lower portion of the side member 4 is attached to the case body 1 by the first attachment bolt 31.

FIG. 11 shows a fourth embodiment. The present embodiment basically has the same configuration and the same function and effect as the first embodiment.
