Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] The present application claims priority to Korean Patent Application No. 10-2023-0091235 filed on Jul. 13, 2023, the entire contents of which application is incorporated herein for all purposes by this reference. Technical Field

[0003] The present invention relates to a supporting device for a pressure vessel, and more particularly, to a supporting device for a pressure vessel which can have a simplified structure and improve space utilization and design freedom. Background Art

[0004] The hydrogen-powered vehicle is configured to generate electricity through a chemical reaction between hydrogen and oxygen, and travels by driving an electric motor. The hydrogen-powered vehicle includes a 2 ) pressure vessel, configured to pass hydrogen and oxygen (O 2 ) between the electrolyte, a fuel cell stack configured to generate electricity through an oxidation-reduction reaction between the electrolyte and the electrolyte, various types of devices configured to discharge the generated water, a battery configured to store the electricity generated by the fuel cell stack, a controller configured to convert and control the generated electricity, and a motor configured to generate driving force.

[0005] A Type IV pressure vessel may be used as a pressure vessel for a hydrogen-powered vehicle. The Type IV pressure vessel may include an inner liner (eg, a non-metallic material) and a carbon fiber layer manufactured by winding a carbon fiber composite material around an outer surface of the inner liner.

[0006] Meanwhile, attempts have recently been made to install a pressure vessel in a space between longitudinal beams (or side frames) of a hydrogen-powered vehicle in order to ensure space utilization while ensuring driving stability (ensuring rear visibility) of the hydrogen-powered vehicle (eg, a hydrogen-powered truck).

[0007] However, it is usually necessary to set a separate support device in the space between the longitudinal beams to support the pressure vessel, which complicates the structure. In addition, it is necessary to ensure a space of a predetermined size or larger for installing the support device, which reduces space utilization and design freedom.

[0008] Furthermore, generally, both the pressure vessel and the supporting device need to be disposed together in the space between the longitudinal beams, which makes it difficult to increase the size (volume) of the pressure vessel to a predetermined size (volume) or more to increase the running distance of the vehicle.

[0009] Therefore, various studies have been conducted recently to simplify the structure for supporting (fixing) a pressure vessel and to improve space utilization and design freedom, but the research results are still insufficient. Therefore, it is necessary to develop a technology for simplifying the structure for supporting (fixing) a pressure vessel and to improve space utilization and design freedom.

[0010] The information included in the Background of the Invention is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgment or any form of suggestion that this information forms the prior art already known to a person skilled in the art. Summary of the invention

[0011] The present invention is directed to providing a supporting device for a pressure vessel, which can have a simplified structure and improve space utilization and design freedom.

[0012] Various aspects of the present invention are directed to providing a pressure vessel with a transverse frame portion configured to support longitudinal beams.

[0013] Among other things, the present invention is directed to providing a pressure vessel support device wherein the cross frame portion is configured to support the pressure vessel while simultaneously being used to support the longitudinal beams such that the pressure vessel may be installed in the space between the longitudinal beams without requiring a separate pressure vessel support device.

[0014] The present invention also seeks to selectively vary the mode and frequency of the longitudinal beams by selectively adjusting the dimensions of the cross frame portions.

[0015] The present invention also aims to increase the storage capacity of the pressure vessel (the amount of hydrogen stored) and increase the driving range of the vehicle.

[0016] The present invention also aims to improve structural rigidity, stability and reliability.

[0017] An exemplary embodiment of the present invention provides a support device for a pressure vessel, comprising: a first longitudinal beam, a second longitudinal beam, and a transverse frame portion, wherein the first longitudinal beam is configured to be joined to an object; the second longitudinal beam is spaced apart from the first longitudinal beam; the transverse frame portion connects the first longitudinal beam and the second longitudinal beam, and supports the pressure vessel between the first longitudinal beam and the second longitudinal beam.

[0018] This is to simplify the structure and improve space utilization and design freedom.

[0019] That is, it is usually necessary to provide a separate support device in the space between the longitudinal beams to support the pressure vessel, which complicates the structure. In addition, it is necessary to ensure a space of a predetermined size or larger for installing the support device, which reduces space utilization and design freedom. In addition, usually, both the pressure vessel and the support device need to be provided together in the space between the longitudinal beams, which makes it difficult to increase the size (volume) of the pressure vessel to a predetermined size (volume) or larger and thus to increase the driving distance of the vehicle.

[0020] In contrast, according to the exemplary embodiment of the present invention, the pressure vessel can be supported by the transverse frame portion connecting the first longitudinal beam and the second longitudinal beam. Therefore, it is possible to obtain advantageous effects of simplifying the structure and improving space utilization and design freedom.

[0021] According to an exemplary embodiment of the present invention, the cross frame portion itself is configured to support the first longitudinal beam and the second longitudinal beam, and is also configured to support the pressure vessel, so that the pressure vessel can be installed (supported and fixed) in the space between the first longitudinal beam and the second longitudinal beam without the need for a separate pressure vessel support device.

[0022] The lateral frame portion may have various structures configured to support the pressure vessel between the first longitudinal beam and the second longitudinal beam while connecting the first longitudinal beam and the second longitudinal beam in the leftward / rightward direction of the object.

[0023] According to an exemplary embodiment of the present invention, the cross frame portion may include: a first cross member and a second cross member, the first cross member is configured to connect the first longitudinal beam and the second longitudinal beam and surround a portion of the outer peripheral surface of the pressure vessel; the second cross member is configured to connect the first longitudinal beam and the second longitudinal beam and surround another portion of the outer peripheral surface of the pressure vessel.

[0024] According to an exemplary embodiment of the present invention, the first cross member may include a first curved surface seating portion in which the outer circumferential surface of the pressure vessel may be received.

[0025] As described above, in the exemplary embodiment of the present invention, the pressure vessel is in close contact (surface contact) with the first curved surface seating portion. Therefore, the advantageous effects of more stably maintaining the arrangement state of the pressure vessel relative to the first cross member and minimizing the movement and sway of the pressure vessel can be obtained.

[0026] According to an exemplary embodiment of the present invention, the second cross member may include a second curved surface seating portion in which the outer peripheral surface of the pressure vessel may be received.

[0027] As described above, in the exemplary embodiment of the present invention, the pressure vessel is in close contact (surface contact) with the second curved surface seating portion. Therefore, the advantageous effects of more stably maintaining the arrangement state of the pressure vessel relative to the second cross member and minimizing the movement and swing of the pressure vessel can be obtained.

[0028] According to an exemplary embodiment of the present invention, the transverse frame portion may be configured to be selectively movable between the first longitudinal beam and the second longitudinal beam in the length direction of the pressure vessel.

[0029] As described above, since the transverse frame portion is movable in the length direction of the pressure vessel, in response to the size of the pressure vessel, the transverse frame portion can be arranged at an optimal position where the transverse frame portion can stably support the pressure vessel.

[0030] According to an exemplary embodiment of the present invention, a supporting device for a pressure vessel may include: a first side fastening hole, a first fastening hole, a first fastening member, a second side fastening hole, a second fastening hole, and a second fastening member, wherein the first side fastening hole is formed in at least one of a first longitudinal beam and a second longitudinal beam; the first fastening hole is formed in a first transverse member and corresponds to the first side fastening hole; the first fastening member is fastened to the first side fastening hole and the first fastening hole; the second side fastening hole is formed in at least one of the first longitudinal beam and the second longitudinal beam; the second fastening hole is formed in a second transverse member and corresponds to the second side fastening hole; the second fastening member is fastened to the second side fastening hole and the second fastening hole.

[0031] According to an exemplary embodiment of the present invention, the first side fastening holes may be provided as a plurality of first side fastening holes spaced apart from each other along the length direction of the pressure vessel, and the second side fastening holes may be provided as a plurality of second side fastening holes spaced apart from each other along the length direction of the pressure vessel.

[0032] As described above, in the exemplary embodiment of the present invention, a plurality of first side fastening holes are spaced apart from each other along the length direction of the pressure vessel, and a plurality of second side fastening holes are spaced apart from each other along the length direction of the pressure vessel. Therefore, in response to the size of the pressure vessel, the transverse frame portion can be arranged at an optimal position where the transverse frame portion can stably support the pressure vessel, and then the transverse frame portion can be fixed relative to the first longitudinal beam and the second longitudinal beam.

[0033] According to an exemplary embodiment of the present invention, the first cross member and the second cross member may jointly surround the entire outer circumferential surface of the pressure vessel.

[0034] According to an exemplary embodiment of the present invention, at least one of the first cross member and the second cross member may include: a first movable cross member and a second movable cross member; the second movable cross member is configured to be selectively movable toward or away from the first movable cross member in the length direction of the pressure vessel.

[0035] According to an exemplary embodiment of the present invention, the eigenmode frequencies of the first and second longitudinal beams may be selectively varied based on movement of the second movable cross member relative to the first movable cross member (movement toward or away from the first movable cross member).

[0036] As described above, in the exemplary embodiment of the present invention, the eigenmode frequencies of the first longitudinal beam and the second longitudinal beam are selectively changed based on the movement of the second movable transverse member relative to the first movable transverse member (the distance between the first movable transverse member and the second movable transverse member). Therefore, it is possible to obtain an advantageous effect of minimizing (suppressing) the resonance of the first longitudinal beam and the second longitudinal beam caused by external vibration (e.g., vibration of the road surface) without replacing the transverse frame (e.g., the first transverse member).

[0037] The movement of the second movable cross member relative to the first movable cross member may be implemented in various ways depending on the required conditions and design specifications.

[0038] According to an exemplary embodiment of the present invention, a supporting device for a pressure vessel may include: a moving member configured to selectively move the second movable cross member toward or away from the first movable cross member.

[0039] According to an exemplary embodiment of the present invention, the supporting device of the pressure vessel may include: a first threaded hole and a second threaded hole, wherein the first threaded hole is formed in a first movable transverse member and is threadedly fastened to one end of the movable member; the second threaded hole is formed in a second movable transverse member and is threadedly fastened to the other end of the movable member; wherein, in response to the rotation of the movable member, the first movable transverse member and the second movable transverse member can move toward or away from each other.

[0040] According to an exemplary embodiment of the present invention, a maximum spacing between the second movable cross member and the first movable cross member may be defined within a maximum length of the pressure vessel in a length direction of the pressure vessel.

[0060] For reference, the pressure vessel supporting device 10 according to the exemplary embodiment of the present invention may be used to support the pressure vessel 20 on various objects each having longitudinal beams (first longitudinal beams and second longitudinal beams).

[0064] The pressure vessel 20 may have various structures configured to store the target fluid. The present invention is not restricted or limited by the type and structure of the pressure vessel 20.

[0065] For example, the pressure vessel 20 may include a liner, a carbon fiber layer disposed around an outer surface of the liner, and a glass fiber layer disposed around an outer surface of the carbon fiber layer.

[0066] Hereinafter, an example in which the pressure vessel 20 includes an accommodation space having a circular cross section will be described. According to another exemplary embodiment of the present invention, the pressure vessel may have a quadrangular cross-sectional shape or other cross-sectional shapes.

[0068] The first longitudinal beam 110 may have various structures according to required conditions and design specifications. The present invention is not restricted or limited by the structure and shape of the first longitudinal beam 110 .

[0069] For example, the first longitudinal beam 110 may have approximately Alternatively, the first longitudinal beam 110 may have an “I”-shaped cross section or other cross-sectional shapes.

[0070] The second longitudinal beam 120 is provided to the object and is spaced apart from the first longitudinal beam 110 to prevent the object from warping and bending in forward / rearward and leftward / rightward directions of the body of the object while ensuring structural rigidity of the body of the object.

[0071] The second longitudinal beam 120 may have various structures according to required conditions and design specifications. The present invention is not restricted or limited by the structure and shape of the second longitudinal beam 120.

[0072] For example, the second longitudinal beam 120 may have approximately Alternatively, the second longitudinal beam 120 may have an “I”-shaped cross section or other cross-sectional shapes.

[0073] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The cross frame portion 200 is configured to prevent the object from warping and bending in the forward / rearward and left / right directions of the vehicle body, and supports the pressure vessel 20 between the first longitudinal beam 110 and the second longitudinal beam 120, while ensuring the structural rigidity of the vehicle body of the object and the first longitudinal beam 110 and the second longitudinal beam 120.

[0074] In this case, the structure in which the transverse frame portion 200 supports the pressure vessel 20 can be understood as a structure in which the transverse frame portion 200 fixes the pressure vessel 20 so that the pressure vessel 20 does not move between the first longitudinal beam 110 and the second longitudinal beam 120 or separate from the portion between the first longitudinal beam 110 and the second longitudinal beam 120 .

[0075] The number of the transverse frame parts 200 and the intervals between the transverse frame parts 200 may be variously changed according to required conditions and design specifications. The present invention is not restricted or limited by the number of the transverse frame parts 200 and the intervals between the transverse frame parts 200.

[0076] Hereinafter, an example will be described in which a plurality of pressure vessels 20 are disposed between the first longitudinal beam 110 and the second longitudinal beam 120, and the pressure vessels 20 are respectively supported by a plurality of (e.g., two) transverse frame portions 200. According to another exemplary embodiment of the present invention, each pressure vessel may be supported by a single transverse frame portion.

[0077] The cross frame portion 200 may have various structures configured to support the pressure vessel 20 between the first longitudinal beam 110 and the second longitudinal beam 120 while connecting the first longitudinal beam 110 and the second longitudinal beam 120 in the left / right direction of the object. The present invention is not restricted or limited by the structure of the cross frame portion 200.

[0078] According to an exemplary embodiment of the present invention, the cross frame portion 200 may include: a first cross member 210 and a second cross member 220, wherein the first cross member 210 is configured to connect the first longitudinal beam 110 and the second longitudinal beam 120, and is arranged to surround a portion of the outer peripheral surface of the pressure vessel 20; the second cross member 220 is configured to connect the first longitudinal beam 110 and the second longitudinal beam 120, and is arranged at another portion of the outer peripheral surface of the pressure vessel 20.

[0079] Hereinafter, an example will be described in which the first cross member 210 supports the upper portion of the pressure vessel 20 based on the upward / downward direction (gravity direction), and the second cross member 220 supports the lower portion of the pressure vessel 20 based on the upward / downward direction (gravity direction). According to another exemplary embodiment of the present invention, the first cross member may be configured to support the lower portion of the pressure vessel, and the second cross member may be configured to support the upper portion of the pressure vessel.

[0080] For reference, in the exemplary embodiment of the present invention shown and described above, an example in which the cross frame portion 200 includes two cross members (a first cross member and a second cross member) has been described. However, according to another exemplary embodiment of the present invention, the cross frame portion may include three or more cross members or only one cross member.

[0081] The first cross member 210 may have various structures configured to connect the first and second longitudinal beams 110 and 120 and surround a portion of the outer peripheral surface of the pressure vessel 20 (eg, the upper portion of the pressure vessel). The present invention is not restricted or limited by the structure and shape of the first cross member 210.

[0082] For example, the first cross member 210 may have an approximately straight line shape and be located between the first longitudinal beam 110 and the second longitudinal beam 120 .

[0083] One end of the first cross member 210 may be in close contact with the inner surface of the first longitudinal beam 110 facing the second longitudinal beam 120, and the other end of the first cross member 210 may be in close contact with the inner surface of the second longitudinal beam 120 facing the first longitudinal beam 110. A portion of the outer peripheral surface of the pressure vessel 20 (e.g., the upper portion of the pressure vessel 20) may be supported by the first cross member 210.

[0084] According to an exemplary embodiment of the present invention, the first cross member 210 may include a first curved surface seating portion 212 in which the outer circumferential surface of the pressure vessel 20 may be received.

[0086] As described above, in the exemplary embodiment of the present invention, the pressure vessel 20 is in close contact (surface contact) with the first curved surface seating portion 212. Therefore, the advantageous effects of more stably maintaining the arrangement state of the pressure vessel 20 relative to the first cross member 210 and minimizing the movement and swing of the pressure vessel 20 can be obtained.

[0087] According to another exemplary embodiment of the present invention, the first curved surface seating portion may have a semicircular shape. Alternatively, the pressure container may be configured to be in line contact or point contact with the first curved surface seating portion.

[0088] The second cross member 220 may have various structures configured to connect the first and second longitudinal beams 110 and 120 and surround another portion of the outer peripheral surface of the pressure vessel 20 (eg, the lower portion of the pressure vessel). The present invention is not restricted or limited by the structure and shape of the second cross member 220.

[0089] For example, the second cross member 220 may have an approximately straight line shape and be located between the first longitudinal beam 110 and the second longitudinal beam 120 .

[0090] One end of the second cross member 220 may be in close contact with the inner surface of the first longitudinal beam 110 facing the second longitudinal beam 120, and the other end of the second cross member 220 may be in close contact with the inner surface of the second longitudinal beam 120 facing the first longitudinal beam 110. Another portion of the outer peripheral surface of the pressure vessel 20 (e.g., the lower portion of the pressure vessel) may be supported by the second cross member 220.

[0091] According to an exemplary embodiment of the present invention, the second cross member 220 may include a second curved surface seating portion 222 in which the outer circumferential surface of the pressure vessel 20 may be received.

[0092] For example, the second curved surface seating portion 222 may be defined to have a shape corresponding to the outer peripheral surface of the pressure vessel 20 , and the outer peripheral surface of the pressure vessel 20 may be in close contact (surface contact) with the second curved surface seating portion 222 .

[0093] The first cross member 210 and the second cross member 220 may be provided to jointly surround the entire outer circumferential surface of the pressure vessel 20. For example, the second curved surface seating portion 222 and the first curved surface seating portion 212 may be provided to jointly define a circular shape and surround the entire outer circumferential surface of the pressure vessel 20.

[0094] As described above, in the exemplary embodiment of the present invention, the pressure vessel 20 is in close contact (surface contact) with the second curved surface seating portion 222. Therefore, the advantageous effects of more stably maintaining the arrangement state of the pressure vessel 20 relative to the second cross member 220 and minimizing the movement and swing of the pressure vessel 20 can be obtained.

[0095] Furthermore, in the exemplary embodiment of the present invention, the entire outer peripheral surface of the pressure vessel 20 is in close contact with the first cross member 210 and the second cross member 220, so that the structural rigidity of the pressure vessel 20 can be imparted to the first cross member 210 and the second cross member 220. Therefore, an advantageous effect of further improving the overall bending / torsion rigidity of the vehicle body of the object can be obtained.

[0096] According to another exemplary embodiment of the present invention, the second curved surface seating portion may have a semicircular shape. Alternatively, the pressure container may be configured to be in line contact or point contact with the second curved surface seating portion.

[0097] According to an exemplary embodiment of the present invention, the cross frame portion 200 may be configured to selectively move between the first longitudinal beam 110 and the second longitudinal beam 120 in the length direction of the pressure vessel 20 (ie, the length direction of the first longitudinal beam).

[0098] As described above, since the cross frame portion 200 is movable in the length direction of the pressure vessel 20 , in response to the size of the pressure vessel 20 , the cross frame portion 200 may be arranged at an optimal position where the cross frame portion 200 may stably support the pressure vessel 20 .

[0099] The arrangement state of the transverse frame portion 200 relative to the longitudinal beams (first and second longitudinal beams) can be fixed in various ways according to required conditions and design specifications. The present invention is not restricted or limited by the structure for fixing the transverse frame portion 200 relative to the longitudinal beams.

In a state where the first fastening hole 214 is aligned with the first side fastening hole 112 (aligned to communicate), the first fastening member B1 (e.g., a bolt member) is threadedly fastened to the first side fastening hole 112 and the first fastening hole 214, so that the arrangement state of the first cross member 210 relative to the first longitudinal beam 110 and the second longitudinal beam 120 can be fixed.

[0103] Likewise, the inner circumferential surface of the second side fastening hole 122 and the inner circumferential surface of the second fastening hole 224 may be provided with a threaded portion, and the second fastening member B2 may be threadedly fastened to the threaded portion. In a state where the second fastening hole 224 is aligned with the second side fastening hole 122 (aligned to communicate), the second fastening member B2 (e.g., a bolt member) is threadedly fastened to the second side fastening hole 122 and the second fastening hole 224, so that the arrangement state of the second cross member 220 relative to the first longitudinal beam 110 and the second longitudinal beam 120 can be fixed.

[0104] According to an exemplary embodiment of the present invention, the first side fastening holes 112 can be set as a plurality of first side fastening holes 112 spaced apart from each other at predetermined intervals along the length direction of the pressure vessel 20 (the length direction of the first longitudinal beam), and the second side fastening holes 122 can be set as a plurality of second side fastening holes 122 spaced apart from each other at predetermined intervals along the length direction of the pressure vessel 20.

[0105] As described above, in the exemplary embodiment of the present invention, the plurality of first side fastening holes 112 are spaced apart from each other along the length direction of the pressure vessel 20, and the plurality of second side fastening holes 122 are spaced apart from each other along the length direction of the pressure vessel 20. Therefore, in response to the size of the pressure vessel 20, the cross frame portion 200 can be arranged at an optimal position where the cross frame portion 200 can stably support the pressure vessel 20, and then the cross frame portion 200 can be fixed relative to the first longitudinal beam 110 and the second longitudinal beam 120.

[0106] The process of installing the pressure vessel 20 to the longitudinal beams (the first longitudinal beam 110 and the second longitudinal beam 120 ) may be variously changed according to the required conditions and design specifications. The present invention is not restricted or limited by the process and order of installing the pressure vessel 20 .

[0107] According to the exemplary embodiment of the present invention, after the second cross member 220 is mounted to the first longitudinal beam 110 and the second longitudinal beam 120, the pressure vessel 20 is accommodated on the second cross member 220 to which the first cross member 210 is mounted. Therefore, the cross frame portion 200 itself may be configured to support the first longitudinal beam 110 and the second longitudinal beam 120, and also serve as a supporting device for supporting the pressure vessel 20.

[0108] That is to say, reference Figure 5 , the second cross member 220 may be first installed to the first longitudinal beam 110 and the second longitudinal beam 120. In a state where the second cross member 220 is disposed between the first longitudinal beam 110 and the second longitudinal beam 120, the second cross member 220 may be fixed by the second fastener B2.

[0109] Next, if Figure 6 As shown, the pressure vessel 20 may be arranged (accommodated) on the second curved seating portion 222 of the second cross member 220 .

[0110] Afterwards, if Figure 7 As shown, the first cross member 210 may be installed to the first longitudinal beam 110 and the second longitudinal beam 120 so that the first curved seating portion 212 covers the pressure vessel 20. When the first cross member 210 is disposed between the first longitudinal beam 110 and the second longitudinal beam 120, the first cross member 210 may be fixed by the first fastener B1.

[0111] At the same time, reference Figure 1 and Figure 8 According to an exemplary embodiment of the present invention, at least one of the first cross member 210 and the second cross member 220 may include a first movable cross member 210a and a second movable cross member 210b, and the second movable cross member 210b is configured to selectively move toward or away from the first movable cross member 210a in the length direction of the pressure vessel 20.

[0112] For example, the first movable cross member 210a and the second movable cross member 210b may be configured to have the same size (eg, the same width in the length direction of the pressure vessel 20). Alternatively, the first movable cross member 210a and the second movable cross member 210b may have different sizes.

[0113] According to an exemplary embodiment of the present invention, the eigenmode frequencies of the first and second longitudinal beams 110 and 120 may be selectively changed based on the movement of the second movable cross member 210b relative to the first movable cross member 210a (movement toward or away from the first movable cross member 210a).

[0114] As described above, in the exemplary embodiment of the present invention, the eigenmode frequencies of the first longitudinal beam 110 and the second longitudinal beam 120 can be selectively changed based on the movement of the second movable cross member 210b relative to the first movable cross member 210a (the distance between the first movable cross member and the second movable cross member). Therefore, an advantageous effect of minimizing (suppressing) the resonance of the first longitudinal beam 110 and the second longitudinal beam 120 caused by external vibration (e.g., vibration of the road surface) can be obtained.

[0115] Among other things, in an exemplary embodiment of the present invention, by changing the distance between the first movable cross member 210a and the second movable cross member 210b, the eigenmode frequency of the first longitudinal beam 110 and the second longitudinal beam 120 is selectively changed. Therefore, an advantageous effect of minimizing (suppressing) the resonance of the first longitudinal beam 110 and the second longitudinal beam 120 caused by external vibration can be obtained without changing the cross frame (e.g., the first cross member).

[0116] The movement of the second movable cross member 210b relative to the first movable cross member 210a (the distance between the first movable cross member and the second movable cross member) can be implemented in various ways according to the required conditions and design specifications. The present invention is not restricted or limited by the movement structure of the second movable cross member 210b relative to the first movable cross member 210a.

[0117] According to an exemplary embodiment of the present invention, the supporting device 10 of the pressure vessel may include a moving member MB configured to selectively move the second movable cross member 210 b toward or away from the first movable cross member 210 a .

[0118] The moving member MB may have various structures configured to selectively move the second movable cross member 210b toward or away from the first movable cross member 210a. The present invention is not restricted or limited by the structure of the moving member MB.

[0119] For example, the first movable cross member 210a and the second movable cross member 210b may be configured to move linearly toward or away from each other through the rotation of the moving member MB.

[0120] According to an exemplary embodiment of the present invention, the support device 10 of the pressure vessel may include: a first threaded hole 213a and a second threaded hole 213b, wherein the first threaded hole 213a is provided in the first movable cross member 210a and is threadedly fastened to one end of the moving member MB, and the second threaded hole 213b is provided in the second movable cross member 210b and is threadedly fastened to the other end of the moving member MB. In response to the rotation of the moving member MB, the first movable cross member 210a and the second movable cross member 210b may move toward or away from each other.

[0121] For example, a typical bolt member, which has a straight rod shape and includes threads provided on an outer peripheral surface thereof, may be used as the moving member MB.

[0122] The threads of the first threaded hole 213a and the second threaded hole 213b may be formed in opposite directions, and the first movable cross member 210a and the second movable cross member 210b may move toward or away from each other in response to the rotation of the moving member MB.

[0123] For example, when the moving member MB rotates in a first direction (eg, clockwise), the first movable cross member 210a and the second movable cross member 210b may move away from each other based on the moving member MB.

[0124] On the other hand, when the moving member MB rotates in the second direction (eg, counterclockwise), the first movable cross member 210a and the second movable cross member 210b may move toward each other based on the moving member MB.

[0125] According to an exemplary embodiment of the present invention, the maximum spacing between the second movable cross member 210b and the first movable cross member 210a (the maximum interval between the first movable cross member and the second movable cross member) can be limited within the maximum length of the pressure vessel in the length direction of the pressure vessel 20.

[0126] Meanwhile, in the exemplary embodiment of the present invention shown and described above, an example has been described in which the first movable cross member 210a and the second movable cross member 210b are linearly moved by the rotation of the moving member MB. However, according to another exemplary embodiment of the present invention, only either one of the first movable cross member and the second movable cross member may be configured to be linearly moved by the rotation of the moving member.

[0127] In addition, in the exemplary embodiment of the present invention shown and described above, an example has been described in which the first cross member 210 includes a plurality of cross members (a first movable cross member and a second movable cross member). However, according to another exemplary embodiment of the present invention, the second cross member (rather than the first cross member) may include a plurality of movable cross members, or the first cross member and the second cross member may include a plurality of movable cross members, respectively.

[0128] According to the exemplary embodiments of the present invention described above, advantageous effects of simplifying the structure and improving space utilization and design freedom can be obtained.

[0129] According to the exemplary embodiment of the present invention, the pressure vessel can be supported by the transverse frame portion supporting the longitudinal beam. Therefore, it is possible to obtain advantageous effects of simplifying the structure and improving space utilization and design freedom.

[0130] Among other things, according to an exemplary embodiment of the present invention, the cross frame portion is configured to support the pressure vessel while being used to support the longitudinal beams, so that the pressure vessel can be installed in the space between the longitudinal beams without requiring a separate pressure vessel support device.

[0131] Furthermore, according to the exemplary embodiment of the present invention, the mode and frequency of the longitudinal beam may be selectively changed by selectively adjusting the size of the transverse frame portion.

[0132] Furthermore, according to the exemplary embodiment of the present invention, it is possible to obtain advantageous effects of increasing the storage capacity of the pressure vessel (the amount of stored hydrogen) and increasing the running distance of the vehicle.

[0133] Furthermore, according to the exemplary embodiments of the present invention, advantageous effects of improving structural rigidity, stability, and reliability may be obtained.
