Description

Technical field

[0001] The present disclosure relates to a high pressure container module and fuel cell vehicle. Prior art

[0002] Japanese Patent Application Laid-Open (JP-A) No. 2008-49961 discloses a design in which several container housings (pressure tanks) are placed in an open top housing. This technology involves attaching the valves to each container body, and the valves are connected together by a pipe, for example, a feeding or replenishing pipe. In addition, application TP-A No. 2009-270707 discloses a structure in which several barrel-shaped tanks with hydrogen of different diameters are located in a housing with a handle, and the housing is mounted above the floor in the rear. [0003] The housing described in IP-A No. 2009-270707 is a simple example of transporting hydrogen tanks and, therefore, allows for improvements in terms of resistance to shock loads when installed in a vehicle. As a reciprocal strategy, we can consider the method, in particular, disclosed in JP-A No. 2008-49961, according to which several container bodies are housed in a casing in the form of a box. However, since each container body is equipped with a valve, and the valves are connected together by a pipe, as the number of container bodies increases in order to increase capacity, the design becomes more complex.

SUMMARY OF THE INVENTION

[0004] Taking into account the above circumstances, the present description of the invention discloses a vehicle and a module of high pressure containers, characterized by the possibility of achieving high capacity, as well as a simple and yet resistant to shock loads design.

[0005] A first aspect of the present disclosure discloses a high pressure container module comprising several stacked container bodies, each container body having a cylindrical round shape and having an opening in at least one end portion in its axial direction; a connecting element connected to the opening of each container body and joining together several container bodies, the connecting element comprising a flow channel establishing a connection between the internal cavities of the container bodies with each other; a casing in the form of a box, configured to accommodate several container housings and a connecting element, the casing having a through hole; and a guide tube, which is equipped with a connecting element, bred out of the casing through a through hole in the casing, and to which a valve is connected, which is capable of opening and closing the flow channel.

[0006] In the high pressure container module according to the first aspect, several container bodies with a cylindrical round shape are laid. At least at one end portion in the axial direction of each container body an opening is made, the openings being interconnected by a connecting element. The internal cavities of several container bodies communicate with each other by means of a connecting element. The guide tube is attached to the connecting element and a valve is attached to it. This allows fuel to be poured in and out by opening and closing a separate valve, even if the number of container bodies increases to increase capacity. In particular, several container housings form a module capable of functioning as a single high-pressure container, which makes it possible to increase capacity using a simple structure.

[0007] Several container bodies and a connecting element are placed in a casing in the form of a box, and a guide tube, with which the connecting element is equipped, extends out of the casing through a through hole. Such an arrangement of several container housings in the housing makes it possible to secure the container housings and the connecting element, providing resistance to shock loads. It should be noted that “box form” is understood to mean a form that includes a bottom wall that serves as a support for objects placed in a casing, and a peripheral wall that encloses objects placed in a casing, including a form that does not include in the description.

[0008] Thus, the high pressure container module according to the first aspect of the invention allows for an increase in capacity using a simple structure that provides shock resistance.

[0009] According to the first aspect, the guide tube may be in the middle part of the connecting element in the laying direction of the container bodies.

[0010] In the above configuration, when fueling several container housings is filled with fuel, fuel enters the connecting element through a guide tube located in the middle of the connecting element in the direction of laying of the container housings. This makes it possible to prevent the filling of the respective container bodies with an unequal amount of fuel as compared with the structures in which the guide tube is located on one end portion of the connecting element. Conversely, if the fuel with which the container bodies are filled is supplied outside, approximately the same amount of fuel may be supplied from each container body. This makes it possible to prevent temperature changes of the respective container housings in the housing as a result of pressure changes in the container housings.

[0011] The high pressure container module thus configured can eliminate the temperature change of the respective container bodies in the casing as a result of pressure changes in the container bodies.

[0012] According to the first aspect, the case may comprise a shell including a bottom wall and a peripheral frame-shaped wall protruding upward from the bottom wall and enclosing several container bodies, as well as a closing element. In addition, the peripheral wall of the casing shell has a closed cross-sectional shape.

[0013] In the above configuration, the case comprises a case shell and a closure member, which eliminates the ingress of foreign objects and other similar objects in the case shell. In addition, since the peripheral wall of the shell of the casing has a closed cross-sectional shape, the deformation of the peripheral wall can be suppressed more efficiently compared to structures in which the peripheral wall is made of an element with an open cross section. Ultimately, this reduces the transmission of shock load to the container bodies inside the casing.

[0014] Thus, the high pressure container module, configured according to the above description, is capable of eliminating the ingress of foreign objects into the casing and enhancing the casing resistance to shock loads.

[0015] The first aspect may further provide a mounting bracket on the bottom wall, and the container bodies may be placed using the mounting bracket so that these container bodies do not touch the bottom wall.

[0016] In the above configuration, the container bodies are not in contact with the bottom wall. This allows you to prevent direct transmission of shock load on the container bodies from the bottom wall, if, for example, the casing is in contact with the road surface while the vehicle is running on fuel cells equipped with a high pressure container module. In addition, you can eliminate the noise caused by the contact of the bottom wall and the container bodies.

[0017] Thus, the high pressure container module, configured as described above, is able to enhance shock resistance and suppress the occurrence of noise.

[0018] The first aspect may further provide a load transfer section with a closed cross-sectional shape, which can be placed on at least one of the elements — on the bottom wall or on the closing element — and extend between two opposite edges of the peripheral wall

[0019] In the above configuration, when a load is applied to the case, this load may be transferred to the opposite side of the case through the load transfer portion.

[0020] This improves the ability to withstand the load on the high pressure container module.

[0021] According to the first aspect, the load transfer section may be located on the closing element from the side of the container bodies, an air channel may be formed between the closing element and the load transfer section, and the air channel may comprise a ventilation hole allowing the gas to escape from the body.

[0022] In the above configuration, an air duct is provided on the closure member between the closure member and the load transfer portion, and a vent is provided in the air duct. This prevents gas retention inside the casing due to blocking the release by the load transfer section.

[0023] Thus, the high pressure container module, configured in the manner described above, is capable of efficiently discharging gas contained within the enclosure.

[0024] A second aspect of the present invention provides a fuel cell vehicle comprising a high pressure container module according to the first aspect, wherein the high pressure container module can be placed in the lower part of the vehicle below the floor panel forming the floor surface in the vehicle cabin.

[0025] According to the second aspect of the invention, the high pressure container module is located at the bottom of the vehicle under the floor panel, which allows space for the high pressure container module to be accommodated without reducing the volume of the cabin or luggage compartment space.

[0026] Thus, in a fuel cell vehicle according to the second aspect of the invention, a decrease in the volume of the cabin and luggage compartment can be excluded.

[0027] According to the second aspect of the invention, the container bodies may be stacked in the transverse direction of the vehicle, while the axial direction of the container bodies is the longitudinal direction of the vehicle.

[0028] In the above configuration, the connecting members connecting the container bodies are located on the front or rear side of the vehicle. The fuel supply to the fuel cell stack located in the front or rear of the vehicle can be performed smoothly.

[0029] Thus, the high pressure container module, configured in the manner described above, is capable of smoothly supplying fuel to the fuel cell stack.

[0030] According to the second aspect of the invention, the container bodies may be stacked in the longitudinal direction of the vehicle, while the axial direction of the container bodies is transverse to the vehicle.

[0031] In the above configuration, since the axial direction of the container bodies is the transverse direction of the vehicle, the container body length in the axial direction will not influence, even if the power control unit and other devices located in the front of the vehicle are transferred to the rear vehicle. That is, the length of the container body in the axial direction can be maintained in a specific size, regardless of the size of the components located in the front or rear of the vehicle.

[0032] Thus, the high pressure container module, configured in the manner described above, allows for increased design flexibility.

[0033] According to the second aspect, the container bodies that are laid in the rear of the vehicle in the form of a high pressure container module can be arranged in tiers in the vertical direction of the vehicle.

[0034] In the above configuration, the fuel capacity can be increased by stacking containers.

[0035] Thus, the high pressure container module configured in the manner described above allows an increase in fuel capacity.

[0036] According to the second aspect of the invention, both sides of the rear portion of the casing in the transverse direction of the vehicle can in plan be concave toward the front side of the vehicle.

[0037] In the above configuration, it is possible to eliminate the negative impact of the casing on the peripheral components even if the casing is installed in the rear end portion of the vehicle.

[0038] Thus, a fuel cell vehicle configured in the manner described above is capable of eliminating the negative impact of the casing on peripheral components, while simultaneously maintaining the fuel capacity.

[0040] the First approximate version of the implementation

The following description relates to a fuel cell vehicle 11 in which the high pressure container module 10 is installed in accordance with the first exemplary embodiment, and refers to the attached figures. It should be noted that in the figures the arrows FORWARD, UP and RIGHT indicate, respectively, the forward and upward direction, as well as the right side of the vehicle 11 on the fuel cells. In the following description, unless explicitly stated otherwise, reference to the front, rear, top, bottom, left and right directions refers to the front and rear in the longitudinal direction of the vehicle, the top and bottom in the vertical direction of the vehicle, the left and right side in the vehicle’s transverse direction for orientation in the forward direction.

[0041] As shown in FIG. 1, a fuel cell vehicle 11 (hereinafter referred to as “vehicle 11”) equipped with a high pressure container module 10 according to a first exemplary embodiment, contains a drive engine 12, a fuel cell battery 14 (battery TE) and module 10 high pressure containers.

[0042] As an example, in the first exemplary embodiment, the driving motor 12 is located at the rear of the vehicle. When turning on the drive motor 12, the power of the drive motor 12 is transmitted to the rear wheels 13 through a transmission not shown in the figures.

[0043] The fuel cell battery 14 is located in the front of the vehicle. The fuel cell battery 14 has a multi-layered structure formed by several tiers of individual cells, which are structural units, and serves as a high voltage source. Each individual cell entering the fuel cell battery 14 generates electric energy due to an electrochemical reaction between hydrogen gas coming from the high pressure container module 10 described below and compressed air coming from an air compressor, not shown in the figures. In addition, the vehicle 11 is equipped with a rechargeable battery, not shown in the figures. A battery is a rechargeable battery; it is possible to use a nickel-hydrogen secondary battery, a lithium hydrogen secondary battery, etc. Electric power is supplied to the drive motor 12 from the battery to bring it into action, and the regenerated power from the drive motor 12 is restored due to regenerative braking

[0044] The module 10 of the high-pressure containers is located in the lower part of the vehicle under the floor panel 16 forming the floor surface of the vehicle cabin. In addition, as shown in FIG. 2, the high pressure container module 10 comprises several container bodies 18, pipes 20, 21 serving as connecting elements, a case 22, and a guide pipe 32.

[0045] As shown in FIG. 3, the container bodies 18 are made with an elongated, substantially cylindrical round shape, the longitudinal direction of which coincides with the axial direction. Several buildings 18 containers placed in the same row with each other. By way of example, in the first exemplary embodiment, eleven container bodies 18, the axial directions of which coincide with the longitudinal direction of the vehicle, are placed at even intervals in the transverse direction of the vehicle (for convenience of description, only the left half of the vehicle is shown in Figure 3 and six buildings 18 are shown containers).

[0046] The positions of the front ends of the eleven container bodies 18 in the vehicle are aligned with each other, and the seven container bodies 18 located closest to the center of the vehicle have the same length in the axial direction relative to each other. Two container bodies 18 on the left side of the vehicle and two container bodies 18 on the right side of the vehicle are made with a shorter length in the direction from the front to the rear of the vehicle (axial direction) compared to other container bodies 18. Thus, the rear end portions of these four container housings 18 are offset to the front of the vehicle further than the rear end portions of the other container housings 18.

[0047] As shown in FIG. 2, each of the container bodies 18 includes a shell 24, covers 30, a first reinforcing layer 26 and a second reinforcing layer 28. Each shell 24 has a cylindrical circular shape open at both end portions in the axial direction, and The first exemplary embodiment is made, for example, from an aluminum alloy. However, this is not limited, and the shell 24 may be made of polymer or other similar material.

[0048] The covers 30 are provided on both end portions of each shell 24 in the axial direction. The axial direction of each cover 30 is oriented along the longitudinal direction of the vehicle; and the lid has essentially the shape of a hemisphere projecting in the direction of the outer (axial direction) side of the shell 24. The two end sections of each shell 24 are covered with lids 30. In the first exemplary embodiment, the lid 30 in the front of the vehicle and the lid 30 in the rear parts of the vehicle are identical to each other. In addition, the connecting element 30A protrudes outward in the axial direction from the tip of each cover 30. Each connecting element 30A is equipped with an opening 30B. Holes 30B are connected to pipes 20, 21 described below.

[0049] The first reinforcing layer 26 is provided on the outer circumferential surface of the shell 24. The first reinforcing layer 26 is made of carbon fiber (CFRP). In particular, a carbon fiber sheet impregnated with thermosetting resin, in particular, epoxy resin, is wrapped around the outer peripheral surface of the shell 24 and heated to form the first reinforcing layer 26. Although not shown in the figures, the fibers of the first reinforcing layer 26 are oriented in the circumferential direction of the shell 24 .

[0050] A second reinforcing layer 28 is provided on the outer circumferential surface of the first reinforcing layer 26. The second reinforcing layer 28 is made of carbon fiber (CFRP). In particular, CFRP filaments impregnated with thermosetting resin, in particular, epoxy resin, are wrapped around the outer peripheral surfaces of the first reinforcing layer 26 and covers 30, and then heated to form the second reinforcing layer 28. Although not shown in the figures, the fibers of the second reinforcing layer 28 are oriented in the axial direction of the shell 24 or in a direction located at a predetermined angle relative to the axial direction.

[0051] The container bodies 18 formed in the manner described above are connected together in the vehicle’s transverse direction by pipes 20, 21. The pipe 20 is an elongated pipe extending in the vehicle’s transverse direction (i.e., in the direction of installation of the container bodies 18) and placed in the front of the housings 18 containers relative to the vehicle. The pipe 20 is equipped with fasteners 20A attached to the fasteners 30A of the covers 30. Several fasteners 20A are provided according to the positions of the container bodies 18, with eleven of the fasteners 20A provided in the first exemplary embodiment. Each fastener 20A has an external thread protruding toward the corresponding container body 18, and the opening CEP (connecting element 30A) of the lid 30 is screwed onto the external thread, thereby fixing the container bodies 18 to the pipe 20. Inside the pipe 20, a flow channel is formed the cavities of several container bodies 18 communicate with each other through this flow channel. In addition, the pipe 20 is equipped with several front fastening plates 36. The front fastening plates 36 will be described in detail below.

[0052] The guide tube 32 is located on the middle portion of the tube 20 in the vehicle's transverse direction (i.e., the middle portion in the laying direction of the container bodies 18). In the first exemplary embodiment, the guide tube 32 is a cylindrical body protruding from the tube 20 in the direction of the front of the vehicle and placed on the fastening element 20A in the middle of the tube 20 along the transverse direction of the vehicle. The guide tube 32 exits through the through-hole 46A, formed in the peripheral wall 46 of the casing 22 (see below). The valve 34, made with the possibility of opening and closing the flow channel through the pipe 20, is attached to the guide pipe 32.

[0053] The pipe 21 is located at the rear of the vehicle relative to the container bodies 18. The rear parts of the containers 18 are connected to each other in the transverse direction of the vehicle pipe 21. The pipe 21 is equipped with several (eleven in the first exemplary embodiment) fasteners 21A, similar to pipe 20. In the fasteners 21A, mounting holes are made through which the connecting elements 30A are inserted covers 30. As shown in FIG. 3, the pipe 21 is attached to the container bodies 18 by screwing the bolts 23 into the holes 30B (see FIG. 2) of the connecting elements 30A from the outside along the axle direction in the position in which the connecting elements 30A are inserted through the fastening members 21A. In addition, a flow channel is formed inside the pipe 21, and the internal cavities of several container bodies 18 communicate with each other through this flow channel. As shown in figure 2, the pipe 21 is equipped with several rear mounting plates 38. The rear mounting plates 38 will be described in detail below.

[0054] The container bodies 18 and the pipe 20 are housed in the casing 22. The casing 22 is made essentially in the form of a rectangular duct in a horizontal projection and contains the casing 40 of the casing and the closing element 42.

[0055] The casing shell 40 is in the form of a box open from the upper side and comprises a bottom wall 44 and a peripheral wall 46. The bottom wall 44 is made of an aluminum alloy or other similar material and has a substantially rectangular shape with rounded corners in horizontal projection . The fastening holes 44A are made at intervals around the outer peripheral part of the bottom wall 44, which allows the bottom wall 44 to be attached to the frame elements, for example, supports, by means of fastening elements, for example bolts.

[0056] The peripheral wall 46 projects upwardly from the bottom wall 44 and is extruded from an aluminum alloy. The peripheral wall 46 has a rectangular shape. The size of the outer contour of the peripheral wall 46 is sufficient to wrap around several container bodies 18, and in the first exemplary embodiment, the size of the peripheral wall 46 is sufficient to accommodate eleven container bodies 18.

[0057] The peripheral wall 46 comprises a front wall 48 extending in the vehicle lateral direction in the front part of the vehicle, a rear wall 50 extending in the vehicle lateral direction in the rear part of the vehicle, as well as a right wall 52 and a left wall 53 connecting together the two end portions of the front wall 48 and the rear wall 50 in the longitudinal direction of the vehicle. The front wall 48, the rear wall 50, the right wall 52 and the left wall 53 are made with a closed cross-sectional shape. The following is described in detail above.

[0058] As shown in FIG. 4, the front wall 48 is made with a closed cross-sectional shape when viewed in the transverse direction of the vehicle. In particular, the front wall 48 comprises a front and rear pair of front vertical walls 48A protruding upward from the bottom wall 44 with an interval between them in the longitudinal direction of the vehicle, the front top wall 48 V connecting the upper end portions of the front vertical walls 48A to each other in the front to the back and the front intermediate wall 48C connecting the vertical intermediate portions of the front vertical walls 48A to each other in the direction from front to back.

[0059] As shown in FIG. 2, a through hole 46A passing through the front wall 48 in the longitudinal direction of the vehicle is formed in the front wall 48 in the middle part of the transverse direction of the vehicle. As shown in FIG. 3, the guide tube 32 provided on the tube 20 exits the casing 22 through the through hole 46A. In addition, the valve 34, made with the possibility of opening and closing the flow channel through the pipe 20, is fixed to the guide pipe 32. This allows you to adjust the amount of fluid flowing through the flow channel. One end of the pipe, not shown in the figure, is connected to the valve 34, and the other end of this pipe is connected to a fuel cell battery or other similar unit.

[0060] As shown in FIG. 5, the rear wall 50, like the front wall 48, is formed with a closed cross-sectional shape when viewed in the transverse direction of the vehicle. In particular, the rear wall 50 comprises a front and rear pair of rear vertical walls 50A protruding upward from the bottom wall 44 with an interval between them in the longitudinal direction of the vehicle, the rear top wall 50B connecting the upper end portions of the rear vertical walls 50A to each other in the direction front to back, and the rear intermediate wall 50C connecting the vertical intermediate portions of the rear vertical walls 50A to each other in a direction from front to back.

[0061] As shown in FIG. 2, when viewed in the longitudinal direction of the vehicle, the right wall 52 and left wall 53 have a closed cross-sectional shape, like the front wall 48 and the rear wall 50. The right wall 52 includes a pair of left and right vertical the walls 52A protruding upward from the bottom wall 44 with a gap between them in the transverse direction of the vehicle, the right upper wall 52B connecting the upper end portions of the right vertical walls 52A from left to right, and the right intermediate a wall 52C connecting the vertical intermediate portions of the right vertical walls 52A from each other from left to right. The left wall 53 includes a pair of left and right vertical walls 53A protruding upward from the bottom wall 44 with an interval between them in the vehicle transverse direction, the left upper wall 53B connecting the upper end portions of the left vertical walls 53A from left to right, and left an intermediate wall 53C connecting the vertical intermediate portions of the left vertical walls 53A from each other from left to right. The peripheral wall 46 is made in the form of a frame element with a closed cross-sectional shape corresponding to the above description.

[0062] As shown in FIG. 3 on a horizontal projection, the concave portions 51 concave toward the front of the vehicle are formed in the transverse direction of the vehicle on both sides of the rear end portion of the peripheral wall 46 (only the concave portion 51 on the left is shown in FIG. 3 vehicle). Thus, the length of the inner cavity of the casing 22 in the longitudinal direction of the vehicle at the two end sections will be less in the transverse direction of the vehicle than in the middle part in the transverse direction of the vehicle. Thus, the container bodies 18, located on both sides in the transverse direction of the vehicle, have a shorter length in the longitudinal (axial) direction of the vehicle than the other container bodies 18, as described above.

[0063] As shown in FIG. 2, the covering element 42 is made in the form of a flat plate of aluminum alloy or another similar material and has a contour corresponding to the contour of the peripheral wall 46. Thus, the concave portions 42A are concave on a horizontal projection to the front of the vehicle , are formed by the corresponding peripheral wall 46 at the rear end of the closing element 42 at both end sections in the transverse direction of the vehicle. As shown in Figures 4 and 5, the step 42B is formed along the outer peripheral edge portion of the covering element 42. A portion on the peripheral outer side of the step 42B overlaps the upper surface of the peripheral wall 46 and is attached thereto with fasteners, for example, bolts. The upper opening of the casing shell 40 is closed by a closing element 42. It should be noted that a gap is formed between the closing element 42 and the container bodies 18, forming a structure that suppresses, for example, noise due to the contact between the closing element 42 and the container bodies 18.

[0064] As shown in FIG. 2, the first mounting brackets 60 serving as the mounting brackets are provided on the vehicle portion of the bottom wall 44 relative to the vehicle. Several first mounting brackets 60 are disposed at intervals in the vehicle’s transverse direction, while in the first example The embodiment has three first mounting brackets 60.

[0065] As shown in FIG. 4, the first mounting brackets 60 are attached to the bottom wall 44 and the front wall 48 (peripheral wall 46) and support the pipe 20. Each first mounting bracket 60 includes a support portion 60A, a stand 60B, and a protruding portion 60C.

[0066] The support portion 60A is a unit in the form of a flat plate, made with a substantially rectangular shape in plan, and is located at a location separated from the bottom wall 44 in the direction of the upper part of the vehicle. Three pillars 60B extend towards the bottom wall 44 from the support portion 60A from the rear edge and two edges in the vehicle's transverse direction (in FIG. 4, only the 60B pillar extending to the rear of the vehicle and the 60B pillar extending to the right side are shown vehicle). Each of the racks 60B is directed diagonally downward from the supporting part 60A in the direction of the bottom wall 44, and the lower end portion of each rack 60 B is bent so that it runs along the bottom wall 44 and joins the bottom wall 44.

[0067] The forward protruding portion 60C extends diagonally upward from the front edge of the support portion 60A towards the peripheral wall 46. The front end portion of the protruding 60C portion is bent upwards so that it extends along the peripheral wall 46 and is connected to the front wall 48 there is a peripheral wall 46).

[0068] The front fastening plates 36 are attached to the pipe 20. Each front fastening plate 36 extends down from the area between adjacent fastening portions 20A of the pipe 20, and the lower end portion of each front fastening plate 36 is equipped with a flange 36A bent to the rear of the vehicle. Each flange 36A overlaps with the supporting part 60A of the corresponding first mounting bracket 60 and is attached thereto by a bolt 100 and a nut 102.

[0069] As shown in FIG. 2, second mounting brackets 62 serving as mounting brackets are provided on the rear wall portion of the bottom wall 44 relative to the vehicle. Several second mounting brackets 62 are arranged at intervals in the transverse direction of the vehicle, while in the first example The embodiment has three second fixing brackets 62 (only two second fixing brackets 62 are shown in FIG. 2). The second fastening brackets 62 are provided in positions corresponding to the first fastening brackets 60 in the vehicle's transverse direction.

[0070] As shown in FIG. 5, the second mounting brackets 62 are attached to the bottom wall 44 and support the pipe 21. Each of the second mounting brackets 62 includes a bearing portion 62A and a support 62B.

[0071] The support portion 62A is a unit in the form of a flat plate, made with a substantially rectangular shape in plan, and is located at a location separated from the bottom wall 44 in the direction of the upper part of the vehicle. In the central portion of the support part 62A, a first mounting hole 62C is made, passing through the support part 62A in the direction of its thickness. Four pillars 62B extend from the front, rear, left, and right end sections of the support part 60A towards the bottom wall 44. Each rack 62B is directed diagonally downward from the support part 62A towards the bottom wall 44, and the bottom end section of each rack 62B is bent so that it runs along the bottom wall 44 and joins the bottom wall 44.

[0072] The rear fastening plates 38 are attached to the pipe 21. Each rear fastening plate 38 extends downward from an area between adjacent fastening portions 21A of the pipe 21, and the lower end portion of each rear fastening plate 38 is equipped with a flange 38A bent to the front of the vehicle.

[0073] The second mounting hole 38B is provided in each flange 38A. The second mounting hole 38B is an elongated hole, the orientation of the longitudinal axis of which coincides with the direction of the axis of the container bodies 18. The bolt 104 is inserted through the first fixing hole 62C, formed in the supporting part 62A of the second fixing bracket 62, and through the second fixing hole 38B on the flange 38A. The bolt 104 is screwed with the nut 106 on the underside of the bearing part 62A, thus connecting the bearing part 62A and the flange 38A.

[0074] A polymer bushing 63 is provided between each second mounting bracket 62 and each rear mounting plate 38. Polymer bushing 63 is connected to support portion 62A and flange 38. Polymer bushing 63 is formed by upper bushing 64 and lower bushing 65. Upper bushing 64 includes upper ring 64A, extended along the axial direction of the bolt 104. The inner diameter of the upper ring 64A is slightly greater than the diameter of the stem of the bolt 104 inserted into the upper ring 64A. The flange 64B extends radially outward from the upper end portion of the upper ring 64A.

[0075] The lower sleeve 65 includes a lower ring 65A extended along the axial direction of the bolt 104. The upper ring 64A is inserted into the lower ring 65A. The upper flange 65B extends radially outward from the upper end portion of the lower ring 65A, and the upper flange 65B is placed between the flange 64B of the upper sleeve 64 and the flange 38A of the rear mounting plate 38. The lower flange 65C extends radially outward from the lower end portion of the lower ring 65A, and the lower flange 65C is placed between the flange 38A of the rear mounting plate 38 and the supporting part 62A of the second mounting bracket 62. Thus, the rear mounting plates 38 can be moved in the axial direction of the container bodies 18 relative to the second mounting brackets 62.

[0076] The pipe 20 and the pipe 21 at both ends of the container bodies 18 are supported respectively on the first fixing brackets 60 and the second fixing brackets 62. In particular, the container bodies 18 are supported by the first fixing brackets 60 and the second fixing brackets 62 in a position in which the container bodies 18 are not in contact with the bottom wall 44 (i.e., in a position raised above the bottom wall 44).

[0077] Uses and Benefits

The following description relates to the use and benefits of the first exemplary embodiment of the invention.

[0078] the Module 10 of the high pressure containers mounted on the vehicle 11 in the first exemplary embodiment, contains several buildings 18 containers, made with a round cylindrical shape, laid, as shown in figure 2. The corresponding body 18 of the containers are connected together on one end portion in the axial direction with the help of pipe 20, and on the other end section in the axial direction with the help of pipe 21. The internal cavities of the container bodies 18 communicate with each other through pipes 20, 21. Directed yuschaya pipe 32 is provided on the pipe 20 and the valve 34 fixed to the guide tube 32. This allows the fuel fill or supply fuel by opening and closing the individual valve 34, even if the number of container bodies 18 is increased to increase the capacitance. In particular, several container housings 18 form a module functioning as a single high-pressure container, which allows capacity to be increased using a simple structure. In addition, since the pipe 20 is located on the front side of the vehicle relative to the module 10 of the high pressure containers, a smooth supply of fuel to the fuel cell battery 14 located in the front of the vehicle is possible.

[0079] In addition, in the first exemplary embodiment, the container bodies 18 and pipes 20, 21 are housed in a box-shaped casing 22, and the guide pipe 32 leaves the pipe 20 out of the casing 22. This placement of several containers 18 in the casing 22 helps to secure container bodies 18 and pipes 20, 21, providing resistance to shock loads. Thus, the high pressure container module 10 according to the first exemplary embodiment allows the capacity to be increased using a simple structure providing resistance to shock loads.

[0080] Furthermore, the first exemplary embodiment provides for a structure in which the valve 34 is attached to a guide tube 32 extending to the outside of the housing 22; this provides access to the valve 34 even when the closing element 42 of the casing 22 overlaps. In particular, it is not necessary to open the closing element 42 in order, for example, to detach the pipe from the valve 34; this allows you to increase operational reliability compared with designs in which the valve 34 is provided inside the casing 22.

[0081] Furthermore, in the first exemplary embodiment, since the guide tube 32 is located in the middle portion in the laying direction of the container bodies 18, when filling several container bodies with fuel through the tube 20, the fuel passes through the guide tube 32 connected to the middle portion of the tube 20 and almost evenly enters each of the buildings of 18 containers. This helps to prevent the uneven filling of the respective container bodies 18 with fuel. In addition, if the fuel with which the container bodies 18 are filled is supplied to the outside, approximately the same amount of fuel can be supplied from each container body 18. With very high internal pressure in the container body 18, changes in pressure lead to large temperature fluctuations. However, in the first exemplary embodiment, the amount of fuel in each of the container bodies 18 is changed to an approximately equal amount. This makes it possible to prevent temperature changes of the respective container bodies 18 in the case 22 as a result of pressure changes in the container bodies 18.

[0082] In addition, in the first exemplary embodiment, the casing 22 includes a casing shell 40 and a covering element 42, which prevents the entry of foreign objects and other similar objects into the casing shell 40. Since the peripheral wall 46 of the casing 40 has a closed cross-sectional shape, the deformation of the peripheral wall 46 can be suppressed more efficiently compared to structures in which the peripheral wall 46 is in the form of a plate. This allows you to prevent the transfer of shock loads on the containers 18 in the casing 22. In particular, it is possible to prevent the penetration of foreign objects into the casing 22 and to increase the resistance of the casing 22 to shock loads.

[0083] In addition, in the first embodiment, the container bodies 18 are supported by the first mounting brackets 60 and the second mounting brackets 62 in a position in which the container bodies 18 are not in contact with the bottom wall 44. In particular, the container bodies 18 are raised above the bottom wall 44. This prevents direct transfer of the shock load to the container bodies 18 from the bottom wall 44, for example, when the housing 22 contacts the road surface. In addition, you can eliminate the noise caused by the contact of the bottom wall 44 and the housings 18 of the containers.

[0084] In addition, as shown in FIG. 1, the high pressure container module 10 is placed under the floor panel 16 of the vehicle 11 according to the first embodiment, which allows the cavity to be securely fixed to accommodate the high pressure container module 10 without reducing the volume of the cabin or luggage space offices. In addition, as shown in figure 2 in plan, both sides in the longitudinal direction of the vehicle rear casing 22 are concave to the front of the vehicle, thereby preventing the corners of the rear end part of the casing 22 from colliding with peripheral components, such as tires, without reducing fuel capacity.

[0085] In the first exemplary embodiment, the positions of the front extremities relative to the vehicle of the eleven container bodies 18 are aligned with each other, as shown in Figure 3. However, the invention is not limited to this embodiment, and, for example, allows the configuration of the embodiment shown in figure 6.

[0086] an implementation option

As shown in FIG. 6, in the high-pressure container module 70 according to this embodiment, several container bodies 18 are laid in the transverse direction of the vehicle, and the axes of their axes coincide with the longitudinal direction of the vehicle. Seven buildings 18 containers located in the Central part in the longitudinal direction of the vehicle, made so that their length in the axial direction was the same.

[0087] The two container bodies 18 on the left side of the vehicle and two container bodies 18 on the right side of the vehicle are designed so that their length in the longitudinal direction of the vehicle (i.e. in their axial direction) is less than the length of the other container bodies 18. The rear ends of these four container housings 18 are located closer to the front side of the vehicle than the rear ends of the other container housings 18. In addition, the front ends of these four container bodies 18 are located closer to the rear side of the vehicle than the front ends of the other container bodies 18. To improve the visibility in FIG. 6, the module 70 of high-pressure containers is shown in a simplified form, and the pipes 20, 21 and valve 34 are not shown.

[0088] A high pressure container module 70 is attached to a pair of left and right supports 72 extending in the longitudinal direction of the vehicle. A pair of left and right front side member 74 is located on the front side of the supports 72 relative to the vehicle. figure placed in the form of tiers. The rear ends of the front side members 74 are curved so that they protrude laterally to the inside and the rear side of the vehicle and join the supports 72.

[0089] A pair of left and right rear side member 76 is located on the rear side of the supports 72 relative to the vehicle. Suspension member 77 is mounted on rear side members 76. Drive motor 12 is located in plan between suspension member 77 and high pressure container module 70. The front ends of the rear side members 76 are curved so that they protrude in the vehicle’s transverse direction towards the inside and the front side of the vehicle and are connected to the supports 72.

[0090] Both ends in the transverse direction of the vehicle of the rear wall 50 forming the peripheral wall 46 of the shell 40 of the casing of the module 70 of high-pressure containers are designed to form concave portions 51 concave in plan to the front of the vehicle. In addition, both extremities in the transverse direction of the vehicle of the front wall 48, forming the peripheral wall 46, are made in the form of concave portions 71, concave in plan towards the rear of the vehicle. In other words, the peripheral wall 46 of the shell casing 40 has a shape in which the central portion of the vehicle is enlarged in the longitudinal direction of the vehicle. This configuration allows you to increase the length of the buildings 18 containers in the axial direction and to maintain fuel capacity, while eliminating the negative impact between the casing 40 of the casing, the frame elements and the peripheral elements of the vehicle.

[0091] the Second approximate version of the implementation

The following description relates to the module 80 of the high-pressure containers in accordance with the second exemplary embodiment, and refers to figures 7-9. Configurations similar to the first exemplary embodiment have the same reference symbols and are not accompanied by detailed explanations.

[0092] As shown in FIG. 7, the high-pressure container module 80 according to the second exemplary embodiment has a configuration similar to the first exemplary embodiment, except for the casing 22. The casing 22 according to the second exemplary embodiment has a substantially rectangular box shape and contains the casing 40 of the casing and the closing element 81.

[0093] The casing shell 40 is in the form of a box open from the upper side, and comprises a bottom wall 44 and a peripheral wall 46. The bottom wall 44 is made of an aluminum alloy or other similar material and has a substantially rectangular shape with rounded corners. The peripheral wall 46 protrudes upward from the bottom wall 44 and is made of a structural element of extruded aluminum alloy. The peripheral wall 46 has a rectangular shape. The peripheral wall 46 comprises a front wall 48 extending in the vehicle transverse direction in the front of the vehicle, a rear wall 50 extending in the vehicle transverse direction in the rear part of the vehicle, as well as a right wall 52 and a left wall 53 connecting the two end portions front wall 48 and rear wall 50 together in the longitudinal direction of the vehicle.

[0094] The lower reinforcing elements 82 serving as the load transfer section are located on the upper surface side (i.e., on the container body 18) of the bottom wall 44. For example, in the second exemplary embodiment, three lower reinforcing elements 82 are provided between opposite portions of the peripheral wall 46 spaced apart in the longitudinal direction of the vehicle. In particular, the lower reinforcing elements 82 are configured to connect the right wall 52 and the left wall 53 of the peripheral wall 46.

[0095] Each of the lower reinforcing elements 82 is made essentially in the form of a hat profile, open to the underside of the vehicle, when viewed in the transverse direction of the vehicle. The flange portions 82A extend from the front and rear extremities of the lower reinforcing element 82 along the bottom wall 44. The flange sections 82A are attached to the bottom wall 44 superimposed on the bottom wall 44. Thus, the bottom reinforcement element 82 together with the bottom wall 44 forms a closed cross-section .

[0096] The closing element 81 is made in the form of a plate of aluminum alloy or another similar material and has a shape corresponding to the peripheral wall 46. Through holes 81A are made at four corner portions of the closing element 81. The gas inside the casing 22 can be released medium through the through holes 81A.

[0097] The upper reinforcing elements 84, serving as a load transfer section, are located on the lower surface side (i.e., on the side of the container bodies 18) of the case 22 (i.e. closing element 81). For example, in the second exemplary embodiment, three upper reinforcing elements 84 are provided, spaced from each other along the longitudinal axis of the vehicle and extending in the transverse direction of the vehicle from one side of the closing element 81 to the other side thereof. The three upper reinforcing elements 84 are arranged at positions corresponding to the lower reinforcing elements 82.

[0098] As shown in figure 8A, each of the upper reinforcing elements 84 is made essentially in the form of a hat profile, open to the underside of the vehicle, when viewed in the transverse direction of the vehicle. The flange portions 84A extend from the front and rear extremities of the upper reinforcing element 84 along the closing member 81. The flange portions 84A are attached to the closing member 81, while overlapping it. Thus, the upper reinforcing element 84 together with the closing elements 81 forms a closed cross-sectional profile.

[0099] As shown in FIG. 7, the convex portions 86 are formed in the central part of the covering element 81 in the vehicle transverse direction. The convex portions 86 are formed in positions corresponding to the upper reinforcing members 84, and, as shown in FIG. 8B, are formed by partially bending the closure member 81 so as to overlap the upper reinforcing member 84. As a result, between the convex portion 86 and the upper reinforcing member 84 is formed cavity serving as the air channel 88.

[0100] On the convex portion 86, a vent hole 86A is formed. The vent hole 86A is provided in the air duct 88 and is adapted to discharge gas flowing in the air duct 88 to the outside.

[0101] Uses and Benefits

The following description relates to the use and advantageous effects of the second exemplary embodiment of the invention.

[0102] In the case of, for example, a collision, when the load acts on the case 22, according to a second exemplary embodiment, the load can be transferred to the side of the case 22 opposite to the side of the collision by means of upper reinforcing elements 84 and lower reinforcing elements 82. For example, as shown 9, in the event of a side collision with a vehicle and the application of a shock load to the left side support of the vehicle 72, the shock load is distributed to the upper reinforcing elements 84 and the lower e reinforcing members 82 through the left wall 53, and is transmitted in the vehicle width direction. Then the shock load is transmitted to the right side support 72 of the vehicle through the right wall 52. Such a transfer of the load can improve the characteristics of the carrying capacity.

[0103] In particular, since the reinforcing elements serving as a load transfer section are provided on the bottom wall 44 of the casing 22 and on the covering member 81, the number of load transfer paths is increased compared to a configuration in which the reinforcing elements are provided only on the bottom wall 44 or closing element 81, and the bearing capacity is improved.

[0104] In addition, an air channel 88 is provided between the closing element 81 and each of the upper reinforcing elements 84, in which a vent hole 86A is provided. This allows you to prevent gas retention in the casing 22 due to overlapping of the release of the upper reinforcing elements 84 and to ensure the effective release of gas from the inside of the casing 22 to the outside.

[0105] In the second exemplary embodiment, reinforcing elements are provided both on the bottom wall 44 of the casing 22 and on the closing element 81, and this configuration is not restrictive. For example, configurations are possible in which only upper reinforcing elements 84 or only lower reinforcing elements 82 will be provided. Although in such configurations the number of load transfer paths may be less than in configuration with upper reinforcing elements 84 and lower reinforcing elements 82, the carrying capacity characteristics will be higher than in the version without reinforcing elements.

[0106] In addition, in the second exemplary embodiment, the upper reinforcing elements 84 are placed on the lower surface of the covering element 81, and the lower reinforcing elements 82 are placed on the upper surface of the lower wall 44. However, the invention is not limited to this option, and, for example, a configuration in which the upper reinforcing elements 84 will be placed on the upper surface of the closing element 81. This configuration is also characterized by the efficiency of the transmission of the impact of the collision to the opposite visions side. However, in the case of placing the upper reinforcing elements 84 on the upper surface of the closing element 81, the upper reinforcing elements 84 will project towards the upper part of the vehicle. Therefore, from the point of view of maintaining the volume of space, it is preferable to place the upper reinforcing elements 84 on the lower surface of the closing element 81.

[0107] the Third approximate version of the implementation

The following description relates to a high pressure container module 90 according to a third exemplary embodiment, and refers to figures 10-11. Configurations similar to the first exemplary embodiment have the same reference symbols and are not accompanied by detailed explanations.

[0108] As shown in FIG. 10, the high pressure container module 90 in the third exemplary embodiment includes several cylinder-shaped container bodies 18. The container bodies 18 are arranged in the longitudinal direction of the vehicle, and the directions of their axes coincide with the transverse direction of the vehicle.

[0109] In addition, the container bodies 18 arranged in the rear of the vehicle of the high pressure container module 90 are arranged in tiers in the vertical direction of the vehicle. That is, the container bodies 18 are arranged in several tiers in the rear side of the vehicle of the high pressure container module 90. In particular, as shown in FIG. 11, the first tier of container bodies 18 comprises thirteen container bodies 18 arranged in the longitudinal direction of the vehicle. Three housings 18 containers stacked on four of the thirteen housings 18 containers on the back side. The three container housings 18 form the second tier and are placed, respectively, in positions between pairs of the container tier 18 of the first tier (i.e., in a staggered pattern).

[0110] Two container bodies 18 are laid on the second tier of container bodies 18. These two container housings 18 form the third tier and are located, respectively, in the positions between the pairs of container housings 18 of the second tier (that is, in a staggered pattern). Thus, the three tiers of the container bodies 18 are formed in the rear side of the vehicle of the high pressure container module 90.

[0111] As shown in FIG. 10, the container bodies 18 are housed in the casing 92. The casing 92 has in plan the shape of a substantially rectangular box and contains a casing shell 94 and a closing element 91 (see also FIG. 11).

[0112] The casing shell 94 is in the form of a box open from the upper side, and comprises a bottom wall 95 and a peripheral wall 96. The bottom wall 95 is made of an aluminum alloy or other similar material and has a substantially rectangular shape with rounded corners.

[0113] The peripheral wall 96 comprises a front wall 96A extending in the vehicle lateral direction in the front part of the vehicle, a rear wall 96B extending in the vehicle lateral direction in the rear part of the vehicle, as well as a right wall 96C and left wall 96D connecting two end portions of the front wall 96A and the rear wall 96B together in the longitudinal direction of the vehicle. The front wall 96A, the rear wall 96B, the right wall 96C and the left wall 96D are made, respectively, with a closed cross-sectional shape.

[0114] In the horizontal projection, front concave portions 97, concave toward the rear of the vehicle, are provided on both sides in the vehicle transverse direction of the front wall 96A. In addition, the rear concave portions 98, concave toward the front of the vehicle, are provided on both sides of the rear wall 96B in the transverse direction of the vehicle.

[0115] As shown in FIG. 11, the covering member 91 is superimposed on the upper surface of the peripheral wall 96 of the case shell 94 and secured thereto with fasteners, for example, bolts. The closing member 91 according to the third exemplary embodiment comprises steps. In particular, the closing element 91 contains steps, so that the rear part of the closing element 91 relative to the vehicle is located above its front part, with the result that the height of the closing element 91 corresponds to the height of three tiers of the container bodies 18.

[0116] The module 90 of high-pressure containers is placed under the floor panel 99 of the vehicle, and part of the module 90 of high-pressure containers with a multi-layered arrangement of the container bodies 18 serves as an element on which rear passenger seats are mounted.

[0117] As shown in FIG. 10, the high pressure container module 90 is attached to a pair of left and right supports 72 extending in the longitudinal direction of the vehicle. A pair of left and right front side member 74 is located on the front side of the supports 72 relative to the vehicle. The front side members 74 are oriented in the longitudinal direction of the vehicle, while the fuel cell battery 14 and the power control unit (PCU), not shown in the figure , arranged in several tiers. The rear ends of the front side members 74 are curved so that they protrude laterally to the inside and the rear side of the vehicle and join the supports 72.

[0118] A pair of left and right rear side members 76 are located on the rear side of the supports 72 relative to the vehicle. Suspension element 77 is mounted on rear side members 76. Drive motor 12 is arranged in plan between suspension member 77 and high pressure container module 70. The front ends of the rear side members 76 are curved so that they protrude laterally to the inside and to the front side of the vehicle and join the supports 72.

[0119] In addition, the reinforcing elements 92 connecting the front side members 74 and the rear side members 76 are oriented along the longitudinal direction of the vehicle. Module 90 high-pressure containers located in the plan between the reinforcing elements 92.

[0120] Uses and Benefits

The following description relates to the use and benefits of the third exemplary embodiment of the invention.

[0121] In the third exemplary embodiment, since the axis of the container bodies 18 is oriented in the vehicle transverse direction, the length of the container body 18 in the axial direction will not be limited even if the fuel cell battery 14 and the power control unit located in the front of the vehicle will be moved to the back of the vehicle. That is, it is possible to maintain a certain length of the container body 18 in the axial direction, regardless of the size of the components located in the front or rear of the vehicle. This allows greater design flexibility.

[0122] In addition, in the third exemplary embodiment, the fuel (hydrogen gas) capacity can be increased by stacking the container bodies 18 in tiers. In particular, the container bodies 18 are stacked in tiers using the space under the rear passenger seats, which prevents a decrease in cabin volume.

[0123] Explanations are given for the high pressure container module and the fuel cell vehicle in accordance with the first, second, and third exemplary embodiments. However, various implementations are possible within the scope of the invention, not beyond the scope of the present description. For example, in the above-described exemplary embodiment, both end portions in the axial direction of the container bodies 18 are connected to each other via pipes 20, 21. However, this design is not restrictive, and it is possible that only the front ends of the container bodies 18 will be connected together pipe 20. Even in such cases, several container housings 18 may form a section functioning as a single high pressure container, due to the communication of the internal cavities to pusov containers 18 with each other through the pipe 20.

[0124] In addition, in the above-described exemplary embodiments, each container body 18 is composed of a case shell 24, a first reinforcement layer 26, a cover 30 and a second reinforcement layer 28. However, the foregoing is not restrictive. For example, a variant is possible in which the container bodies 18 are not equipped with a second reinforcing layer 28, and the casing 22 will be strengthened to increase the resistance to shock loads. In addition, the materials and the orientation of the fibers of the first reinforcing layer 26 and the second reinforcing layer 28 can be changed in the most appropriate way, in accordance with the resistance to shock loads required for the containers 18.

[0125] In addition, in the above-described exemplary embodiments, the housing 22 is configured from the case shell 40 and the cover member 42. However, the foregoing is not restrictive. For example, the casing 22 can only be assembled from the casing shell 40 without the covering element 42. In addition, a variant is possible in which the peripheral wall 46 will directly contact the floor panel 16, as a result of which the floor panel 16 will function as the covering element of the casing cover 40 .

[0126] In addition, there are no special restrictions on the arrangement of the container bodies 18 and the shape of the casing 22. For example, in the first exemplary embodiment, the container bodies 18 are stacked in a single row (tier) in the transverse direction of the vehicle. A two-tiered configuration is also applicable, in which the container bodies 18 will stack on top of the other container bodies 18.
