[0003] The present invention relates to a storage container support assembly for supporting a storage container. Background Art

[0004] In recent years, as awareness of environmental crises and depletion of petroleum resources increases, research and development of electric vehicles (environmentally friendly vehicles) have attracted much attention. Examples of electric vehicles include plug-in hybrid electric vehicles (PHEVs), battery electric vehicles (BEVs), fuel cell electric vehicles (FCEVs), and the like.

[0005] FCEVs include a fuel cell stack that generates electricity using hydrogen, a storage container that stores the hydrogen, and a battery pack that stores electricity generated by regenerative braking.

[0006] FCEV basically requires a storage tank that stores a large amount of hydrogen to increase mileage. In order to ensure a long-range FCEV, the storage tank has a cylindrical shape extending in the width direction of the vehicle.

[0007] Safety equipment such as valves may be engaged by nozzles located at the ends of the storage container in the width direction of the vehicle. Meanwhile, the storage container may expand or contract in the axial direction due to high-pressure hydrogen, so a support assembly for more stably supporting the storage container is required. Summary of the invention

[0042] Some embodiments of the present invention will be described in detail below with reference to the exemplary drawings. When adding reference numerals to the components of each drawing, it should be noted that the same or equivalent components are represented by the same reference numerals even if they are shown on different drawings. In addition, when describing the embodiments of the present invention, the detailed description of related known configurations or functions will be omitted when it is determined that the detailed description interferes with the understanding of the embodiments of the present invention.

[0043] In the description of components of embodiments of the present invention, terms such as first, second, A, B, (a) and (b) may be used. These terms are intended only to distinguish one component from other components, and these terms do not limit the nature, order or sequence of the components. Unless otherwise defined, all terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by those of ordinary skill in the art to which the present invention belongs. It should also be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant field, and unless clearly defined herein, should not be interpreted in an idealized or overly formal sense.

[0044] The following will refer to Figures 1 to 9 Embodiments of the present invention are described in detail.

[0045] Figure 1 is a schematic diagram showing a storage container according to an embodiment of the present invention. Figure 2 is an exploded perspective view of a nozzle and a storage container support assembly disposed in the "A" portion of a storage container according to an embodiment of the present invention.

[0046] refer to Figure 1 and Figure 2 The storage container 1 for storing high-pressure hydrogen may be cylindrical extending in the width direction (eg, X direction) of the vehicle, and may include a pair of nozzles 2 provided at both ends thereof. The storage container 1 may include a hydrogen storage tank 1 .

[0047] A pair of nozzles 2 may be provided to introduce hydrogen into or extract hydrogen from the storage container 1, and a stabilizing device such as wiring (not shown) may be coupled to the nozzles 2. The pair of nozzles 2 may be formed into a cylindrical shape extending in the longitudinal direction (length direction) of the storage container 1.

[0048] A pair of nozzles 2 disposed at both ends of the storage container 1 may be supported by a pair of mounting necks 10 and 20. Each mounting neck 10 or 20 may have a cylindrical shape. The diameter of each mounting neck 10 or 20 may be smaller than the diameter of the cylindrical part of the storage container 1 and larger than the diameter of the cylindrical part of each nozzle 2.

[0049] The mounting necks 10 and 20 may include a storage container fixing assembly 10 for fixing a first nozzle disposed at one end of the storage container 1 , and a storage container supporting assembly 20 for supporting a second nozzle 2 disposed at the other end of the storage container 1 .

[0050] Although not shown in the drawings, the storage container fixing assembly 10 may be directly fixed to the first nozzle via threads on the outer circumferential surface of the cylindrical portion of the first nozzle. The storage container fixing assembly 10 may fix the first nozzle to prevent the first nozzle from moving.

[0051] In addition, the storage container 1 may contain high-pressure hydrogen gas in the interior thereof. The storage container 1 may expand or contract in the radial direction of the body portion having a cylindrical shape, and may expand or contract in the axial direction of the nozzle part.

[0052] In particular, when high-pressure hydrogen is injected into the storage container 1, such as when the storage container 1 is being filled, the storage container 1 may expand in the longitudinal direction (e.g., X direction) and in the radial direction (Z direction). On the other hand, when high-pressure hydrogen escapes from the interior of the storage container 1, such as when a vehicle having the storage container 1 is traveling, the storage container 1 may contract in the longitudinal direction and in the radial direction.

[0053] When the storage container 1 expands or contracts, each nozzle of the storage container 1 may tend to be displaced in the axial direction (eg, X direction). However, the first nozzle of the storage container 1 is fixed by the storage container fixing assembly 10, and thus can be prevented from being displaced in the axial direction.

[0054] When the displacement of the first nozzle 2 and the second nozzle 2 of the storage container 1 in the axial direction is blocked, the main body of the storage container 1 may be further deformed. Therefore, the second nozzle 2 of the storage container 1 may be supported not by the storage container fixing assembly 10 but by the storage container supporting assembly 20, so that the second nozzle 2 is deformed in the axial direction.

[0055] Unlike the storage container fixing assembly 10 , the storage container supporting assembly 20 may support the second nozzle 2 in such a manner that the second nozzle 2 is displaceable in the axial direction.

[0056] The reason why the position of the first nozzle of the storage container 1 is fixed by the storage container fixing assembly 10 is to prevent interference with other components such as wiring connected to the first nozzle.

[0057] In addition, the embodiments of the present invention are not limited thereto, and the second nozzles 2 may be provided at both ends of the storage container 1 , and thus each of the pair of second nozzles 2 may be supported by the storage container support assembly 20 .

[0058] The storage container support assembly 20 may be formed so that the second nozzle 2 is inserted therein and may support the second nozzle 2. The second nozzle 2 may rotate in a state of being inserted into the storage container support assembly 20.

[0059] The storage container support assembly 20 may include: a spherical inner ring 30 coupled to the second nozzle 2; and a spherical outer ring 40 for receiving the spherical inner ring 30 and coupled to a frame (not shown) of a vehicle through a fastening member “F”.

[0060] The spherical inner ring 30 can be inserted through the inner ring hole 40a and joined to the spherical outer ring 40 (see Figure 3 ), and the spherical inner ring 30 can be coupled to the second nozzle 2 through the nozzle hole 30a.

[0061] The structures of the spherical inner ring 30 and the spherical outer ring 40 will be described in detail below.

[0062] Figure 3 is an exploded perspective view of a storage container support assembly according to an embodiment of the present invention. Figure 4 is a cross-sectional view illustrating a spherical outer ring and a spherical inner ring according to an embodiment of the present invention. Figure 5 1 is a perspective view of a state in which a spherical inner ring is inserted into an inner ring hole according to an embodiment of the present invention. Figure 61 is a perspective view of a state in which a spherical inner ring inserted into an inner ring hole rotates relative to a spherical outer ring according to an embodiment of the present invention. Figure 7 1 is a perspective view of a state in which the rotation of the spherical inner ring relative to the spherical outer ring is completed according to the embodiment of the present invention.

[0063] refer to Figures 3 to 7 , the spherical inner ring 30 and the spherical outer ring 40 may have a structure of a spherical bearing.

[0064] The spherical inner ring 30 may include a spherical inner ring body 31, which forms a nozzle hole 30a, a second nozzle 2 (see Figure 2 ) is inserted into the nozzle hole 30a. The spherical inner ring body 31 may be provided in a ring shape to have a sliding surface 31a having a portion of a spherical outer surface.

[0065] When the spherical inner ring 30 is inserted into the inner ring hole 40a, the sliding surface 31a may serve as a surface that slides while in contact with the spherical outer ring 40. In more detail, when the spherical inner ring 30 is inserted into the inner ring hole 40a, the sliding surface 31a may slide while in contact with the inner surface 41a of the spherical outer ring 40. In addition, the sliding surface 31a may be a surface that slides and rotates relative to the spherical outer ring 40.

[0066] The nozzle hole 30 a may have a circular hole shape when viewed on the central axis of the nozzle hole 30 a , and the spherical inner ring body 31 may have an annular shape surrounding the nozzle hole 30 a .

[0067] The spherical outer ring 40 may include a frame engaging portion 45 engaged to the frame, and an inner ring engaging portion 41 forming an inner ring hole 40 a into which the spherical inner ring 30 can be inserted.

[0068] The frame engaging member 45 may include an engaging hole 45a, an engaging member "F" (see Figure 2 A pair of frame engaging members 45 may be provided and may be located on both sides of the inner ring engaging portion 41.

[0069] The inner ring engagement portion 41 may support the spherical inner ring 30 so that the inner ring engagement portion 41 can rotate when the spherical inner ring 30 is inserted into the inner ring engagement portion 41. The inner ring engagement portion 41 may include an inner surface 41a surrounding the sliding surface 31a and formed to correspond to the sliding surface 31a forming a part of the spherical surface.

[0070] The inner surface 41a may extend to surround the inner hole 40a to form the inner hole 40a. When viewed on the central axis of the inner hole 40a, the inner hole 40a may include a circular shape, and the inner ring engagement portion 41 may include an annular shape surrounding the inner hole 40a.

[0071] The inner surface 41a may include a guide groove 42, which is provided on one side of the inner ring hole 40a in the direction of the central axis so that the spherical inner ring 30 can be inserted into the inner ring hole 40a. Here, the term "one side" may be a side facing the spherical inner ring 30 to be inserted into the inner ring hole 40a. The guide groove 42 may be in communication with the inner ring hole 40a.

[0072] The guide surface 42a forming the guide groove 42 may be stepped upward or downward from the inner surface 41a. In other words, the guide surface 42a located on the upper side of the center of the inner ring hole 40a may be stepped upward from the inner surface 41a, and the guide surface 42a located on the lower side of the center of the inner ring hole 40a may be stepped downward from the inner surface 41a.

[0073] Furthermore, the guide surface 42a may extend parallel to the insertion direction of the spherical inner ring 30 and may be connected to the inner surface 41a. That is, the guide surface 42a may extend parallel to the central axis of the inner ring hole 40a in the central axis direction of the inner ring hole 40a.

[0074] As described above, a pair of guide surfaces 42a may be provided to face each other. The pair of guide surfaces 42a may be provided to be symmetrical to each other about the central axis of the inner ring hole 40a.

[0075] The width W1 of the guide groove 42 in the direction perpendicular to the central axis of the inner ring hole 40a (for example, the Y direction) may be greater than or equal to the width W2 of the spherical inner ring 30 in the direction of the central axis of the nozzle hole 30a, so that the spherical inner ring 30 can be inserted into the inner ring hole 40a.

[0076] In addition, the distance "H" between the pair of guide surfaces 42a, i.e., the minimum distance between the pair of guide surfaces 42a, may be greater than or equal to the sliding diameter D3, i.e., the outer diameter of the sliding surface 31a. In other words, the sliding diameter D3 may be less than or equal to the distance "H" between the pair of guide surfaces 42a.

[0077] The sliding diameter D3 may correspond to twice the radius R2 of the sliding surface 31a, which is the distance R2 from the center of the spherical inner ring 30 to the sliding surface 31a of the spherical inner ring 30. Here, when viewed in a cross section perpendicular to the central axis direction of the spherical inner ring 30, the center of the spherical inner ring 30 may be the center of the nozzle hole 30a, and may be the center point at the same distance R2 from the sliding surface 31a.

[0078] In addition, the spacing distance "H" between the pair of guide surfaces 42a may correspond to twice the radius R1 of the inner surface 41a, which is the distance R1 from the center of the spherical outer ring 40 to the inner surface 41a of the spherical outer ring 40. Here, when viewed in a cross section perpendicular to the central axis direction of the spherical outer ring 40, the center of the spherical outer ring 40 may be the center of the inner ring hole 40a, and may be the center point where the distance R1 between the inner surface 41a and the center of the inner ring hole 40a is the same.

[0079] The sliding diameter D3 may be greater than the nozzle hole diameter D2. Meanwhile, the radius R2 of the sliding surface 31a may be equal to or less than the radius R1 of the inner surface 41a. The radius R1 of the inner surface 41a may be a value corresponding to half of the spacing distance "H" between the pair of guide surfaces 42a.

[0080] Due to this structure, when the central axis direction of the nozzle hole 30a and the central axis direction of the inner ring hole 40a are perpendicular to each other, the spherical inner ring 30 can be inserted into the inner ring hole 40a through the guide groove 42.

[0081] The spherical inner ring 30 can be rotatably supported by the spherical outer ring 40 when inserted into the inner ring hole 40a. In order to rotatably support the spherical inner ring 30 in the spherical outer ring 40, it is necessary to prevent the spherical inner ring 30 from being separated from the spherical outer ring 40. For this purpose, when the central axis direction of the nozzle hole 30a and the central axis direction of the inner ring hole 40a are perpendicular to each other, the front end of the spherical inner ring 30 in the insertion direction can be blocked by the spherical outer ring 40, and the rear end thereof can be spaced apart from the spherical outer ring 40. In this case, it should be understood that the rear end of the spherical inner ring 30 is spaced apart from the guide surface 42a of the spherical outer ring 40.

[0082] For more details, see Figure 4 , which illustrates a cross section perpendicular to the central axis of the inner ring hole 40a and the central axis of the nozzle hole 30a, the diameter D1 between the front end portions of the spherical outer ring 40 may be smaller than the sliding diameter D3. In this case, the diameter D1 between the front end portions may represent the minimum spacing distance of the inner surface 41a when viewed in the direction of the central axis of the inner ring hole 40a.

[0083] By adopting this structure, it is possible to prevent the spherical inner ring 30 inserted through the inner ring hole 40a from being inserted further forward than the front end of the spherical outer ring 40.

[0084] In addition, when viewed in a cross section perpendicular to the central axis of the inner race hole 40a, the inner surface 41a may have a curvature in the direction in which the spherical inner race 30 is inserted.

[0085] When viewed in a cross section including the guide surface 42a, as the spherical inner race 30 moves toward the front end in a direction of insertion into the inner race hole 40a, the inner surface 41a may bend so that the cross-sectional area of ​​the inner race hole 40a decreases.

[0086] Furthermore, when viewed in a cross section outside the guide surface 42a, the inner surface 41a of the spherical inner ring 30 in the direction of insertion into the inner ring hole 40a may form a portion of a spherical surface so that the front end and the rear end are symmetrical to each other (see Fig. 9 ).

[0087] According to this structure, when the central axis direction of the inner ring hole 40a and the central axis direction of the nozzle hole 30a are perpendicular to each other, the spherical inner ring 30 can be inserted into the inner ring hole 40a along the guide surface 42a (see Figure 5 ).

[0088] At the same time, due to the sliding surface diameter D3 of the spherical inner ring 30 inserted into the inner ring hole 40a, the front end of the spherical inner ring 30 is blocked by the front end of the spherical outer ring 40, so the spherical inner ring 30 cannot be further inserted into the inner ring hole 40a. In this case, the spherical inner ring 30 can be positioned at the insertion position IP.

[0089] In this case, the rear end of the spherical inner ring 30 may be spaced apart from the guide surface 42a. In this state, the spherical inner ring 30 may rotate relative to the spherical outer ring 40 until the central axis of the inner ring hole 40a and the central axis of the nozzle hole 30a correspond to each other (see Figure 6 ).

[0090] Thereafter, when the central axis of the inner ring hole 40a and the central axis of the nozzle hole 30a correspond to (eg, coincide with) each other, the spherical inner ring body 31 can be fixed while being inserted into the inner ring engagement portion 41 (see Figure 7 ). In this case, the spherical inner ring 30 may be positioned at the locking position LP.

[0091] The following will refer to Figure 8 and Fig. 9 The principle of fixing the spherical inner ring 30 to the spherical outer ring 40 is described.

[0092] Figure 8 is a schematic side cross-sectional view of a storage container support assembly and a second nozzle along a central axis of an inner circle hole according to an embodiment of the present invention. Fig. 9 is a schematic side cross-sectional view of a storage container assembly and a second nozzle according to an embodiment of the present invention.

[0093] exist Figure 8In the cross section of the spherical inner ring 30 including the guide groove 42 of the spherical outer ring 40, the front end of the spherical inner ring 30 is blocked by the front end of the spherical outer ring 40, thereby preventing the spherical inner ring 30 from being further inserted forward. In addition, the rear end of the spherical inner ring 30 may be spaced apart from the guide surface 42a.

[0094] exist Fig. 9 In another cross section of the spherical inner ring 30 shown, which does not include the guide groove 42 of the spherical outer ring 40, the front end of the spherical inner ring 30 is blocked by the front end of the spherical outer ring 40, so that the spherical inner ring 30 can be prevented from being further inserted forward. Moreover, since the rear end of the spherical inner ring 30 is formed to be blocked by the inner surface 41a, the forward or backward movement of the second nozzle 2 of the spherical inner ring 30 in the axial direction can be restricted.

[0095] According to this structure, the problem caused by wear between components can be prevented by the shape of the spherical bearing for simple fitting. In the geometric shape of the embodiment of the present invention, the spherical inner ring 30 will not be separated from the spherical outer ring 40 as long as the spherical inner ring 30 is not rotatably inserted into the inner ring hole 40a of the spherical outer ring 40 in a predetermined direction by an external force.

[0096] That is, although the second nozzle 2 is deformed and rotated, the spherical inner ring 30 can be prevented from being separated from the spherical outer ring 40, thereby preventing safety accidents.

[0097] In addition, according to one embodiment of the present invention, although the storage container 1 (see Figure 1 ) The longitudinal displacement or the distortion of the vehicle body may cause vibration, but the second nozzle 2 of the storage container 1 can still be supported more stably by the storage container support assembly 20, thus preventing safety accidents.

[0098] At the same time, the spherical outer ring 40 can be integrated into one component. As described above, since the spherical outer ring 40 is integrated into one component, even when the second nozzle 2 is displaced in the axial direction or the second nozzle 2 is displaced due to rotation, even due to vibration, etc., the spherical inner ring 30 can be more effectively prevented from being separated from the spherical outer ring 40.

[0099] In this way, when the separation of the spherical inner ring 30 and the spherical outer ring 40 is prevented, safety accidents caused by the separation between components related to the storage container 1 can be more effectively prevented.

[0100] In addition, since the spherical outer ring 40 is integral, the fastening components required for the joint between the spherical outer ring 40 are no longer required, and due to the recessed portion formed on the surface of the spherical outer ring 40, the spherical outer ring 40 can rotatably and stably support the spherical inner ring 30, and at the same time, the weight of the spherical outer ring 40 is reduced, so the weight of the vehicle can be reduced.

[0101] The present invention can support the storage container more stably, thereby preventing collision between the storage containers and thus preventing safety accidents.

[0102] Furthermore, the present invention can resist deformation of the nozzle of the storage container in the axial direction while rotatably supporting the nozzle, thereby preventing separation between the storage container and the storage container supporting assembly.

[0103] Furthermore, in the present invention, since the spherical inner ring coupled to the nozzle of the storage container is supported by the integrated spherical outer ring, the spherical inner ring can be prevented from being separated from the spherical outer ring, safety can be improved, and manufacturing can be facilitated.

[0104] Furthermore, various effects directly or indirectly determined by the present specification can be provided.

[0105] The above description only illustrates the technical spirit of the present invention, and those skilled in the art can make various modifications and changes without departing from the basic characteristics of the present invention.

[0106] Therefore, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention, but are intended to describe exemplary embodiments of the present invention, and the scope of the technical spirit of the present invention is not limited by these embodiments. All technical spirits within the scope equivalent to the protection scope of the present invention should be interpreted as included within the scope of the present invention.
