Holes 25e,... Are formed in the upper surface portion 25a and the lower surface portion 25c of the reinforcing plate 25 at positions corresponding to the holes 23a, 23a of the vehicle body mounting portion 23. Then, cylindrical collars 26, 26 are inserted through holes 25e,... Formed in the upper surface portion 25a and the lower surface portion 25c, and their upper ends are located below the holes 23a, 23a of the vehicle body mounting portion 23. It is joined to the periphery. The bottom frames 3, 3 extend substantially in the left-right direction of the vehicle and connect the two side frames 2, 2. Specifically, as shown in FIG. 4A, each bottom frame 3 includes a bottom panel 11 and a side panel 13 of the case 1.
And is indirectly connected to each side frame 2 via the. The bottom panel 11 of the case 1 has holes 1 at positions corresponding to the collars 26,.
Are formed. Each of the bottom frames 3 has a hole having a diameter larger than the diameter of the head of the bolt 7 at a position corresponding to the hole 11a so that the bolt 7 can be inserted into the hole 11a of the bottom panel 11. .. Are formed. Next, a method of assembling the FC box B and a method of attaching the FC box B to a vehicle body will be described. First, as shown in FIG. 2, a front panel 12, side panels 13, 1
3. The rear panel 14 is joined. The side frames 2 and 2 to which the reinforcing plate 25 and the collar 26 are joined in advance are respectively joined so as to straddle the right side panel 13 and the bottom panel 11 and the left side panel 13 and the bottom panel 11. The mounting panels 4,... And the mounting brackets 5,. Each corner plate 6 is joined to each corner formed by the front panel 12, the side panels 13, 13, and the rear panel 14 so as to straddle the upper end of each panel and the vehicle body mounting portions 22, 23 of each side frame 2. Let it. At this time, the holes 6a,... Of the corner plates 6 are aligned with the holes 22a, 22b, 23a, 23b of the vehicle body mounting portions 22, 23. Then, the bottom frames 3 and 3 are joined to appropriate positions below the bottom panel 11. At this time, FIG.
The holes 3a of the bottom frame 3 are aligned with the holes 11a for attaching the bolts 7 formed at the four corners of the bottom panel 11, as shown in FIG. A fuel cell V and auxiliary equipment (not shown) are installed on the installation panels 4,... And the installation brackets 5,. Then, the cover C is attached to the case 1 via the seal D from above. After the positioning pins P, P attached to the side frames 2 of the FC box B are aligned with the positioning holes (not shown) of the main frame F of the vehicle, the bolts 7 are removed from the holes 3a of the bottom frames 3. The FC box B is inserted immediately below the main frame F. In this way, by attaching the vehicle body mounting portions 22 and 23 of the two side frames 2 and 2 directly below the main frame F, as shown in FIG. Central upper surface 24 of side frame 2
A space that can accommodate the equipment and the like is created between the two. As described above, according to the present embodiment, the following effects can be obtained. (1) Since the space between the main frame F and the central upper surface 24 of the side frame 2 is the space in the case 1, the space below the main frame F can be used effectively. Therefore, for example, piping can be passed through the space, or the fuel cell V can be placed sideways. In addition, by appropriately providing holes in the side frame 2, the bottom panel 1 is provided.
1, pipes can be passed through a closed section formed by the side panel 13 and the side frame 2. (2) By arranging the vehicle body mounting portions 22, 23 reinforced by the reinforcing plate 25 in the FC box B, for example, the section modulus is increased by about 50% from that of the conventional vehicle body mounting portion. The strength of the mounting part is improved. In addition, according to the side frame 2 of the present embodiment with respect to the conventional cross-shaped bone 85, the section modulus can be increased only by changing the height of the central upper surface portion 24. The overall strength can be easily improved. (3) Even in the event of a collision, since the side frame 2 is mounted directly below the main frame F of the vehicle, that is, since the main frame F and the side frame 2 are mounted in parallel, It is resistant to compression in the vertical direction and bending in the vertical direction, and can reliably protect the fuel cell system S in the FC box B including the piping. Further, since the side frames 2 attached in parallel to the main frame F reinforce the main frame F itself, the rigidity of the entire vehicle body can be improved.
Further, the rigidity of the bottom frame 3 against a load in the left-right direction can be improved. As described above, the present invention is not limited to the above embodiment, but can be implemented in various forms. (1) In the present embodiment, the side frame 2 is
Although a member having a substantially L-shaped cross section mainly composed of the vehicle body attachment portions 22 and 23 and the central upper surface portion 24 is used, the present invention is not limited to this, and the front and rear ends of the side frames may extend upward. Any shape may be used. For example, the member constituting the side frame may be a member having a substantially U-shaped cross section or a hollow rod-shaped member. (2) In the present embodiment, two bottom frames 3 are provided, but the present invention is not limited to this, and three or more bottom frames may be provided. (3) In this embodiment, the bottom frame 3 is connected to the side frame 2 via the bottom panel 11 and the side panel 13 of the case 1.
Although the present invention is not limited thereto,
The bottom frame may be joined directly to the side frames.
However, in this case, since the bottom frame is configured to be installed in the FC box, the structure as in the present embodiment is desirable in order to maximize the space in the FC box. According to the first aspect of the present invention, since the space between the main frame and the vicinity of the center of the side frame is the space in the case, the space below the main frame is reduced. It can be used effectively. In addition, even in the event of a collision, the load in the front-rear direction can be received by the main frame and the side frames, so it is resistant to compression and bending, and reliably protects the piping and other fuel cell systems in the fuel cell system box. be able to. Further, the rigidity against the load in the left-right direction can be improved by the bottom frame.
