Means for Solving the Problems

[0006] The tank module according to claim 1 comprises: a first tank module section comprising: a plurality of first tanks arranged in parallel and filled with fluid; a first manifold arranged with the arrangement direction of the plurality of first tanks as the longitudinal direction and enabling the flow of the fluid between the plurality of first tanks; a second tank module section comprising: a plurality of second tanks arranged in parallel and filled with fluid, located below the first tank module section and below the plurality of first tanks; a second manifold located below the first manifold and arranged with the arrangement direction of the plurality of second tanks as the longitudinal direction and enabling the flow of the fluid between the plurality of second tanks; a joint section connected to the first manifold and the second manifold and enabling the flow of fluid between the first manifold and the second manifold; and a bracket to which the first manifold and the second manifold are fixed and which integrate the first manifold and the second manifold. The bracket comprises a first fixing portion fixed to the first manifold, a second fixing portion fixed to the second manifold, and a connecting portion that connects the first and second fixing portions and is fixed to the vehicle. The axial end of the second tank has a neck portion formed to be smaller in outer diameter than other parts, the first tank is formed to be shorter in axial length than the second tank, the first manifold is positioned above the second tank, the first fixing portion is formed along the longitudinal direction of the first manifold, and the second fixing portion is formed along the longitudinal direction of the second manifold. Furthermore, the connecting portion is provided with a fastening portion that is positioned between the neck portions formed on adjacent second tanks in a plan view and fastened to the vehicle. .

[0007] The tank module according to claim 1 comprises a first tank module section, a second tank module section, a joint section, and a bracket. The first tank module section comprises a plurality of first tanks and a first manifold, the plurality of first tanks arranged in parallel, and the first tanks are filled with fluid. The first manifold is arranged with the arrangement direction of the plurality of first tanks as the longitudinal direction, and the first manifold enables the flow of fluid in the first tanks between the plurality of first tanks.

[0008] Furthermore, in the present invention, the second tank module is located below the first tank module and comprises a plurality of second tanks and a second manifold. The plurality of second tanks are located below the plurality of first tanks and arranged in parallel, and the second tanks are filled with fluid. The second manifold is located below the first manifold and is arranged with the arrangement direction of the plurality of second tanks as its longitudinal direction, and the second manifold enables the flow of fluid within the second tanks between the plurality of second tanks.

[0009] Furthermore, in this invention, a joint is connected to the first manifold and the second manifold, allowing fluid to flow between the first manifold and the second manifold via the joint. In addition, brackets are fixed to the first manifold and the second manifold, integrating the first manifold and the second manifold via the brackets.

[0010] As a result, in this invention, the first tank module and the second tank module can be treated as a single tank module. Furthermore, in this invention, the first manifold and the second manifold are fixed together via a bracket, thereby integrating the first tank module and the second tank module and improving the rigidity of the tank module. As a result, relative displacement between the first tank module and the second tank module can be suppressed. Furthermore, in this invention, by fixing the connecting portion to the vehicle while the first fixing portion is fixed to the first manifold and the second fixing portion is fixed to the second manifold, it becomes possible to mount a single tank module, in which the first tank module portion and the second tank module portion are integrated via a bracket, onto the vehicle. Furthermore, in this invention, a neck portion is provided at the axial end of the second tank, and this neck portion is formed to be smaller in outer diameter than other parts. Also, the first tank is formed to be shorter in axial length than the second tank, and the first manifold is positioned above the second tank. Furthermore, the first fixing portion is formed along the longitudinal direction of the first manifold, and the second fixing portion is formed along the longitudinal direction of the second manifold. In addition, a fastening portion is provided at the connecting portion, and the fastening portion is positioned between the neck portions formed on the second tank in a plan view. The connecting portion is fastened (fixed) to the vehicle via this fastening portion. In this invention, the neck portion of the second tank is formed to be smaller in outer diameter than other parts of the second tank, so that a gap is provided between the neck portions of adjacent second tanks. Therefore, in this invention, when viewed from below the vehicle, the fastening portion is exposed through this gap, which improves the workability when fastening the fastening portion to the vehicle. In other words, in this invention, since the fastening portion is exposed through the gap, bolt fastening can be performed from the lower side of the vehicle when mounting the tank module onto the vehicle. Compared to bolt fastening from the upper side of the vehicle, there are no interfering parts, resulting in improved workability.

[0011] The tank module according to claim 2 is the tank module according to claim 1, wherein a valve for controlling the outflow of the fluid is provided at one longitudinal end of the first manifold or the second manifold.

[0012] In the tank module described in claim 2, a valve is provided at one end of the longitudinal direction of the first manifold or the second manifold, and the outflow of fluid is controlled by the valve. In the present invention, the first manifold and the second manifold are connected by a joint, and fluid flows between the first manifold and the second manifold through the joint, so there is no need to provide a valve for each tank, and the number of parts and costs are reduced.

[0020] Claim 3The vehicle equipped with the tank module described in [claim number] is as described in claim 1 or Claim 2 the tank module described, and a pair of left and right side rails extending in the longitudinal direction of the vehicle body, to which the tank module is fastened via a fastening portion that forms part of the bracket and is fastened to the vehicle.

[Figure 3] It is a cross-sectional view schematically showing a state in which the tank module according to the present embodiment is mounted on a vehicle [Figure 4] It is a bottom view showing the tank module according to the present embodiment.

Modes for Carrying Out the Invention

[0024] The tank module according to the present embodiment will be described with reference to the drawings. Note that the arrows FR, UP, and RH appropriately marked in each figure indicate the front direction, upward direction, and the right side of the vehicle 12 on which the tank module 10 is mounted, respectively. Hereinafter, when simply explaining the front-back, up-down, and left-right directions, unless otherwise specified, it shall indicate the front-back in the vehicle front-back direction, the up-down in the vehicle up-down direction, and the left-right in the vehicle width direction when facing the traveling direction.

[0025] (Configuration of the Tank Module) First, the configuration of the tank module 10 according to the present embodiment will be described.

[0026] As shown in FIG. 1, the tank module 10 includes a tank module section (first tank module section) 14 and a tank module section (second tank module section) 16, and the tank module section 14 is disposed above the tank module section 16.

[0027] In the present embodiment, for example, in the tank module sections 14 and 16, a plurality of tanks (first tank) 18 and tanks (second tank) 20 are arranged in parallel along the vehicle front-back direction. The tanks 18 and 20 each have a substantially cylindrical shape, and the tanks 18 and 20 have substantially the same outer diameter dimension. At both axial ends 18A and 18B of the tank 18, a neck portion 22 having a smaller diameter (formed with a smaller outer shape) than other parts of the tank 18 is formed, and at both axial ends 20A and 20B of the tank 20, a neck portion 24 having a smaller diameter than other parts of the tank 20 is formed. Further, the tanks 18 and 20 are each formed of, for example, carbon fiber reinforced resin (CFRP) and filled with hydrogen (fluid) as fuel.

[0028] Furthermore, tank 20 is formed to have a longer axial length than tank 18, and tanks 18 and 20 are positioned vertically with their axial centers aligned. In other words, the axial ends 20A and 20B of tank 20 extend beyond the axial ends 18A and 18B of tank 18. Note that tanks 18 and 20 are positioned vertically with a radial offset equal to their respective radii.

[0029] The tank module section 14 has a manifold (first manifold) 26 provided at one axial end 18A of the tank 18, and a support member 28 provided at the other axial end 18B of the tank 18. The manifold 26 and the support member 28 are each substantially rectangular parallelepipeds, and are arranged with the longitudinal direction of the manifold 26 and support member 28, respectively, in the direction of arrangement of the multiple tanks 18 (vehicle longitudinal direction).

[0030] The manifold 26 and the support member 28 are set so that their height (vehicle vertical direction) is greater than their width (vehicle width direction), and are formed to improve rigidity against forces acting along the vehicle's vertical direction.

[0031] Here, as shown in Figure 2, a flow path 30 is formed within the manifold 26 along its longitudinal direction, allowing hydrogen in the tank 18 to flow. In addition, a flow path 32 is formed within the manifold 26 that communicates with a flow path formed in a nozzle (not shown) connected to one axial end 18A of each tank 18, and each flow path 32 communicates with the flow path 30.

[0032] Furthermore, as shown in Figure 1, a nozzle (not shown) is connected to the other axial end 18B of the tank 18. This nozzle is for sealing purposes, and the other axial end 18B of the tank 18 is connected to the support member 28 via this nozzle in a sealed state.

[0033] On the other hand, similar to the tank module section 14, the tank module section 16 has a manifold (second manifold) 34 at one axial end 20A of the tank 20, and a support member 36 at the other axial end 20B of the tank 20. The manifold 34 and the support member 36 are each substantially rectangular parallelepipeds, and the arrangement direction of the multiple tanks 20 is the longitudinal direction of the manifold 34 and the support member 36, respectively. The manifold 34 and the support member 36 are formed so that their height (vehicle vertical direction) is greater than their width (vehicle width direction).

[0034] Similar to manifold 26, a flow path 38 (see Figure 3) is formed within manifold 34 along the longitudinal direction of manifold 34, allowing hydrogen in tank 20 to flow. Furthermore, a flow path (not shown) is formed within manifold 34 that communicates with a flow path formed in a fitting (not shown) connected to one axial end 20A of each tank 20, and each flow path communicates with flow path 38.

[0035] Furthermore, a nozzle (not shown) is connected to the other axial end 20B of the tank 20, similar to the tank 18, and the other axial end 20B of the tank 20 is connected to the support member 36 via this nozzle in a sealed state.

[0036] In this embodiment, the support members 28 and 36 are formed for the purpose of sealing the other axial ends 18B and 20B of the tanks 18 and 20, but they may also be configured as a manifold. In this case, for example, it is necessary to form flow paths between the multiple tanks 18 and 20 such that the flow direction is unidirectional.

[0037] On the other hand, in this embodiment, one longitudinal end 26A of the manifold 26 and one longitudinal end 34A of the manifold 34 are connected by a joint 40. A flow path for hydrogen, not shown in the figures, is formed within the joint 40, and it is in communication with a flow path 30 (see Figure 3) formed in the manifold 26 and also in communication with a flow path 38 (see Figure 3) formed in the manifold 34.

[0038] Furthermore, a valve 42 is provided on the rear side of one longitudinal end 26A of the manifold 26. This valve 42 controls the outflow of hydrogen, allowing hydrogen in the tanks 18 and 20 to be supplied to the fuel cell unit (not shown). Note that the valve 42 may also be provided at one longitudinal end 34A of the manifold 34, or at a location other than the longitudinal ends 26A and 34A of the manifolds 26 and 34.

[0039] In this embodiment, a bracket 44 is provided between the manifold 26 and the manifold 34, and another bracket 46 is provided between the support member 28 and the support member 36. As described above, the tank module 14 is located above the tank module 16. The tank 20 provided in the tank module 16 is formed to have a longer axial length than the tank 18 provided in the tank module 14, and the axial ends 20A and 20B of the tank 20 are positioned to protrude from the axial ends 18A and 18B of the tank 18, respectively.

[0040] Therefore, in this embodiment, in a front view, the manifold 26 and support member 28 of the tank module 10 are positioned above the manifold 34 and support member 36, respectively, and in a plan view, the manifold 34 and support member 36 are positioned further outward in the vehicle width direction than the manifold 26 and support member 28, respectively.

[0041] The bracket 44 is made of a metal plate and, as shown in Figure 3, includes a fixing portion (first fixing portion) 48 that is fixed to the manifold 26 and a fixing portion (second fixing portion) 50 that is fixed to the manifold 34. The fixing portions 48 and 50 are formed along the longitudinal directions of the manifolds 26 and 34, respectively.

[0042] Furthermore, the bracket 44 is configured to include a connecting portion 52 that connects the fixing portion 48 and the fixing portion 50, and the connecting portion 52 is formed to be the same length as the fixing portion 48 and the fixing portion 50. In other words, in this embodiment, the bracket 44 is formed by bending a rectangular plate material. The fixing portion 50 is fixed to the upper surface 35 of the manifold 34 via bolts 54, etc., and the fixing portion 48 is fixed to the lower surface 27 of the manifold 26 via bolts 56, etc.

[0043] In this embodiment, a vertical dimensional difference is provided between the fixing portion 48 and the fixing portion 50, and an inclined portion 58 is provided on the fixing portion 50 side of the connecting portion 52 to absorb this dimensional difference. The inclined portion 58 is inclined upward as it approaches the manifold 26 side. By forming such an inclined portion 58, the bracket 44 can obtain a reaction force against forces acting along the vertical direction compared to when it is formed as a flat plate. In this embodiment, although the inclined portion 58 is provided on the fixing portion 50 side, the dimensional difference may also be absorbed by providing inclined portions on both the fixing portion 48 side and the fixing portion 50 side.

[0044] Furthermore, in this embodiment, as shown in Figure 1, fastening portions 52A are provided on the connecting portion 52 at a predetermined pitch along the longitudinal direction of the connecting portion 52. Here, as shown in Figure 4, when viewed from the bottom of the tank module 10, multiple tanks 20 are exposed.

[0045] As mentioned above, the tank 20 is substantially cylindrical, and a neck portion 24 is provided at its axial end. Therefore, a gap 60 is provided between the neck portions 24 of adjacent tanks 20. The fastening portion 52A provided on the connecting portion 52 of the bracket 44 shown in Figure 1 is positioned so that it can be exposed through this gap 60. Note that the bracket 46 has substantially the same configuration as the bracket 44, so its description will be omitted.

[0046] In this embodiment, the vehicle 12 shown in Figure 3 is a so-called frame vehicle in which the vehicle body is supported by a ladder frame. The ladder frame comprises a pair of left and right side frames 62, 64 that extend along the longitudinal direction of the vehicle at both ends in the vehicle width direction, and a plurality of cross members (not shown) that are spanned between the pair of left and right side frames 62, 64. At the fastening portion 52A provided on the connecting portion 52 of the brackets 44, 46, the connecting portion 52 is fastened (fixed) to the lower surfaces 62A, 64A of the side frames 62, 64, respectively, via bolts 66 or the like.

[0047] As described above, with brackets 44 and 46 fastened to side frames 62 and 64 respectively, the tank module 10 is fixed to the side frames 62 and 64 via brackets 44 and 46, and the tank module 10 is mounted on the vehicle 12.

[0048] (Operation and effects of the tank module) Next, the operation and effects of the tank module 10 according to this embodiment will be described.

[0049] As shown in Figure 1, the tank module 10 in this embodiment includes a tank module section 14, a tank module section 16, a joint section 40, and brackets 44 and 46. The tank module section 14 is composed of a plurality of tanks 18 and a manifold 26, and the manifold 26 is arranged along the arrangement direction of the plurality of tanks 18 at one axial end 18A side of the plurality of tanks 18. This manifold 26 enables the flow of fluid within the tanks 18 between the plurality of tanks 18.

[0050] Furthermore, the tank module section 16 is located below the tank module section 14 and comprises a plurality of tanks 20 and a manifold 34. The plurality of tanks 20 are located below the plurality of tanks 18 and arranged in parallel, and the manifold 34 is located below the manifold 26 and arranged along the direction of the arrangement of the plurality of tanks 20. This manifold 34 enables the flow of fluid within the tanks 20 between the plurality of tanks 20.

[0051] A joint 40 is connected to manifold 26 and manifold 34, allowing fluid to flow between manifold 26 and manifold 34 via the joint 40.

[0052] As a result, in this embodiment, the tank module section 14 equipped with the manifold 26 and the tank module section 16 equipped with the manifold 34 can be treated as a single tank module 10.

[0053] In this embodiment, the manifold 26 provided on one axial end 18A of the tank 18 and the manifold 34 provided on one axial end 20A of the tank 20 are fixed together via a bracket 44. In addition, the support member 28 provided on the other axial end 18B of the tank 18 and the support member 36 provided on the other axial end 20B of the tank 20 are fixed together via a bracket 46.

[0054] Thus, in this embodiment, the tank module section 14 and the second tank module section 16 are integrated via brackets 44 and 46, improving the rigidity of the tank module 10 and suppressing relative displacement between the tank module section 14 and the tank module section 16.

[0055] Furthermore, in this embodiment, a valve 42 is provided at one end 26A in the longitudinal direction of the manifold 26, and the outflow of fluid is controlled by the valve 42. In this embodiment, a joint portion 40 is connected to the manifold 26 and the manifold 34, and fluid flows between the manifold 26 and the manifold 34 via the joint portion 40, so there is no need to provide a valve for each tank 18 and 20, thereby reducing the number of parts and costs.

[0056] Here, the brackets 44 and 46 will be described in detail. In this embodiment, as shown in Figure 3, bracket 44 is composed of a fixing part 48, a fixing part 50, and a connecting part 52. The fixing part 48 is fixed to the manifold 26, and the fixing part 50 is fixed to the manifold 34. The connecting part 52 connects the fixing part 48 and the fixing part 50, and the connecting part 52 is fixed to the vehicle 12 side. In bracket 46, the fixing part 48 is fixed to the support member 28, and the fixing part 50 is fixed to the support member 36.

[0057] In this manner, the fixing portion 48 of the bracket 44 is fixed to the manifold 26 and the fixing portion 50 is fixed to the manifold 34, and the fixing portion 48 of the bracket 46 is fixed to the support member 28 and the fixing portion 50 is fixed to the support member 36, thereby integrating the tank module 14 and the tank module 16.

[0058] As a result, in this embodiment, as described above, the tank module section 14 and the tank module section 16 form a single tank module 10. In this state, the connecting sections 52 of the brackets 44 and 46 are fixed to the vehicle 12 side. This allows the tank module 10 to be mounted on the vehicle 12.

[0059] Here, we will explain how the connecting portions 52 of brackets 44 and 46 are fixed to the vehicle 12.

[0060] In this embodiment, tanks 18 and 20 are substantially cylindrical in shape, and neck portions 22 and 24, respectively, are formed at the axial ends of tanks 18 and 20, respectively, with a smaller diameter than other parts of tanks 18 and 20. Furthermore, tank 18 is formed to be shorter in axial length than tank 20, and the manifold 26 is positioned above tank 20.

[0061] As described above, the connecting portion 52 of the bracket 44 is provided with a fastening portion 52A. This fastening portion 52A is positioned between the neck portions 24 formed on the tank 20 in a plan view, and the connecting portion 52 can be fastened to the vehicle 12 via this fastening portion 52A.

[0062] In this embodiment, brackets 44 and 46 are fastened to a pair of left and right side frames 62 and 64 that extend along the longitudinal direction of the vehicle. However, as shown in Figure 4, the neck portion 24 of the tank 20 has a smaller diameter than other parts of the tank 20, so a gap 60 is provided between the neck portions 24 of adjacent tanks 20. Therefore, when viewed from below the vehicle, the fastening portion 52A (see Figure 1) is exposed through this gap 60.

[0063] Thus, in this embodiment, the fastening portion 52A is exposed, which improves workability when fastening the fastening portion 52A to the vehicle 12. In other words, in this embodiment, since the fastening portion 52A is exposed through the gap 60, bolt fastening from the lower side of the vehicle is possible when mounting the tank module 10 to the vehicle 12, and compared to bolt fastening from the upper side of the vehicle, there are no interfering parts, resulting in better workability.

[0064] In this embodiment, the tanks 18 and 20 are arranged along the vehicle width direction, but this is not limited to this configuration; they may also be arranged along the vehicle longitudinal direction. In this case, although not shown in the figures, for example, the brackets 44 and 46 are fixed to cross members located at the front and rear of the vehicle.

[0065] In this embodiment, tanks 18 and 20 are substantially cylindrical in shape, but the shape of tanks 18 and 20 is not limited to this, and they may be substantially rectangular in shape. Also, tanks 18 and 20 are given the same outer diameter, but this is not limited to this.

[0066] Furthermore, in this embodiment, the tank 20 is formed to have a longer axial length than the tank 18, but it is not limited to this, and may be formed to have the same length. In this case, for example, the manifold 26 and manifold 34 will be positioned to overlap vertically, but the bracket will be positioned between the manifold 26 and manifold 34 to fix them together, and the connecting portion will protrude inward or outward in the vehicle width direction and be fastened to the vehicle 12.

[0067] <Note> Furthermore, the following configurations may be combined as appropriate to form the tank module and tank module-equipped vehicle according to the present invention.

[0068] (Composition 1) The tank module comprises a first tank module section comprising: a plurality of first tanks arranged in parallel and filled with fluid; a first manifold arranged with the arrangement direction of the plurality of first tanks as the longitudinal direction and enabling the flow of the fluid between the plurality of first tanks; a second tank module section comprising: a plurality of second tanks arranged in parallel and filled with fluid, located below the first tank module section and positioned below the plurality of first tanks; a second manifold located below the first manifold and arranged with the arrangement direction of the plurality of second tanks as the longitudinal direction and enabling the flow of the fluid between the plurality of second tanks; a joint section connected to the first manifold and the second manifold and enabling the flow of fluid between the first manifold and the second manifold; and a bracket to which the first manifold and the second manifold are fixed.
