Referring to fig. 2 to 5, in some embodiments, the gas storage system 100 includes at least one gas storage assembly 10, and in general, the gas storage system 100 includes a plurality of gas storage assemblies 10, each of the gas storage assemblies 10 having a similar structure, and thus the structure of a single gas storage assembly 10 shown in fig. 2 to 5 will be described below. The gas storage assembly 10 includes a plurality of gas cylinders 1 and a fixing frame 2 for vertically fixing the plurality of gas cylinders 1.

The "vertical" mounting is relative to the prior art transverse mounting described previously, where the cylinders are disposed vertically relative to the mounting interface, e.g., vehicle chassis, where the gas storage system is located, rather than parallel as in the prior art. The beneficial effects of this are that, can overcome the frame that transversely sets up heavier, and there is the shortcoming of the potential safety hazard of gas leakage.

The term "fixed frame" as its name implies, means to provide mounting and securement to a plurality of cylinders of the gas storage assembly 10. The fixed frame 2 includes a first frame 21, the first frame 21 defining a first installation space 201, a second installation space 202 being located at the periphery of the first installation space 201, the first frame 21 providing a gas cylinder fastening seat 213 located at the first installation space 201, the second installation space 202, a part of the gas cylinders of the plurality of gas cylinders 1 being disposed in the first installation space 201, another part of the gas cylinders being disposed in the second installation space 202; all of the plurality of gas cylinders 1 are carried by the first frame 21.

Preferably, the gas cylinders located in the first installation space 201 are arranged in a plurality of columns, and the number of gas cylinders arranged in each second installation space 202 is the same as the number of gas cylinders located in the first installation space 201 in the adjacent columns. Thus, the vertical installation and fixation of the gas cylinder can be realized more stably. For example, as shown in fig. 2 to 5, one gas storage assembly 10 has eight gas cylinders 1, four gas cylinders located in the middle are installed and fixed in a first installation space 201 in the form of 2 x 2, namely, two gas cylinders 1 in each row, and the other four gas cylinders 1 are installed and fixed in second installation spaces 202 on the left and right sides of the first frame 21 in a structure of two gas cylinders 1 in a single row.

It should be understood that all of the plurality of cylinders 1 are carried by the first frame 21 in the meaning that the first frame 21 herein is a main frame that supports the fixed frame 2, specifically, for example, as shown in the drawings, the first frame 21 is provided with a cylinder fastening seat 213 not only in the first installation space 201 defined by the first frame 21, but also in the second installation space 202 outside the first installation space 201, with the result that both the cylinders 1 located in the first installation space 201 and the cylinders 1 located in the second installation space 202 are carried by the first frame 21.

Preferably, in some embodiments, the gas storage assembly 10 may further include a second frame 22, where the second frame 22 is located in the second installation space 202 and is located outside the gas cylinder in the second installation space 202, and the second frame 22 may only serve as a non-load bearing gas cylinder for protecting the gas cylinder or providing a mounting site for a skin structure or the like. It will be appreciated that the second frame 22 is an auxiliary frame provided on the side of the first frame 21, rather than serving as a load bearing function. Specifically, the gas cylinders 1 are supported by the first frame 21, and the second frame 22 may be a structure that serves only to protect the gas cylinders or to provide a non-supported gas cylinder for a mounting site of a skin structure or the like, and thus the second frame 22 may be lighter than the first frame 21. For example, the second frame 22 may be thinner than the first frame 21.

The embodiment has the advantages that through the arrangement of the first frame and the gas cylinder fastening seat, on the basis of realizing the vertical installation and fixation of the gas cylinders to realize better safety, the frame structure is simplified, specifically, the bearing of the gas cylinders is borne through the first frame, and the size of the first frame only needs to correspondingly install the first installation space of a part of the gas cylinders, compared with the frame which needs to surround all the gas cylinders, the structure is simplified, the material cost is saved, and the weight reduction performance is better; and, the mounting fixing reliability of the gas cylinders located at the relatively central portion in the array formed by the plurality of gas cylinders is poor with respect to the structure in which the single integral frame encloses all the gas cylinders, whereas the above embodiment has the structure in which the first frames provided with the relatively centers define the first mounting space, and the second mounting space is provided at the periphery of the first mounting space, respectively, so that a larger portion of the gas cylinders can be reliably mounted and fixed.

With continued reference to fig. 2-5, in some embodiments, the specific structure of the first frame 21 for providing the bearing of all the gas cylinders 1 may be that the first frame 21 includes a plurality of columns 211, at least one bearing beam 212 is disposed between the columns 211 disposed adjacently, and two ends of the bearing beam 212 are fixedly connected to the columns 211 disposed adjacently respectively; a cylinder fastening base 213 is provided at the upright 211 and/or the load beam 212, for example the cylinder fastening base 213 may be a structure comprising a circular arc profile for better fastening with the cylinder. Preferably, the fastening piece arranged on the gas cylinder fastening base 213 may be a plurality of hoops 214, and the hoops 214 can hold and fasten the gas cylinder 1 on the side surface of the gas cylinder 1. Three hoops 214 are shown for example in the figures arranged in a vertical direction to clampingly secure the cylinder. The above embodiment has the advantage of facilitating further stable fixation of the gas cylinder 1 in the vertical direction. It will be appreciated that the fastening member 214 has the advantages of reliable fastening effect and easy installation and operation, but the fastening member is not limited to the fastening member, and may be other fastening structures, such as a manner of fixing around the gas cylinder by using a steel chain, a steel wire, etc.

With continued reference to fig. 2-5, in some embodiments, the first frame 21 may be configured such that the first mounting space 201 defined by the first frame 21 is a cube space, and three or all four sides of the cube are provided with load-bearing beams 212 to correspondingly define a "U" or "mouth" shaped structure. The above-mentioned cube structure is a substantial cube structure, including a quadrangular prism structure and also including a truncated cube structure, for example, as shown in fig. 2, a portion located at a corner of the cube has two pillars 211, where the corner is a truncated structure, and is not a quadrangular prism structure, but also belongs to the cube space defined above. As shown in fig. 4 and 5, three or all four sides of the cube are provided with load bearing beams 212, forming a "mouth" shaped structure, which is relatively stable. However, if the strength requirement of the gas storage system is not very high, only three sides may be provided with the load-bearing beams 212, for example, the load-bearing beams 212 located in front as shown in fig. 4 and 5 may be omitted, and the corresponding structure is a "U" -shaped structure, so that the structure of the first frame 21 may be simplified and further lightened. The second installation spaces 202 are respectively located at opposite side surfaces of the first installation space 201, for example, the second installation spaces 202 are respectively located at left and right side surfaces of the first installation space 201 as shown in the drawing. The beneficial effects of adopting above embodiment lie in that, frame construction is comparatively simple and have comparatively stable installation fixed effect.

Referring to fig. 3 and 4, in some embodiments, the gas cylinder 1 located in the first installation space 201 is disposed offset from the gas cylinder located in the second installation space 202. Here, the gas cylinders of the first installation space 201 and the gas cylinders of the second installation space 202 are arranged in a staggered manner, for example, as shown in fig. 3 and 4, for example, the gas cylinders of the first installation space 201 are arranged along a straight line L in the same row of two gas cylinders 1, and the axes a of the gas cylinders 1 respectively positioned at two sides of the gas cylinders are not positioned on the straight line L, so that the gas storage system 100 is provided with a plurality of gas storage assemblies 10 in a staggered manner, the plurality of gas storage assemblies 10 can be compactly arranged, and the space integration degree of the gas storage system 100 is improved. It will be appreciated that in some embodiments, the arrangement may be staggered.

The contoured sleeve 24 is shaped similarly to the shape of one end of the cylinder 1 and thus can fit snugly. The beneficial effects of adopting above embodiment lie in that, the support that provides of bracket 23 bears the weight of the effect can avoid the gas cylinder to drop in vertical direction, and the restriction vertical direction gas cylinder displacement avoids generally that the direct friction of metallic bracket 23 and gas cylinder 1 surface causes the risk simultaneously. The material of the copying bush 24 is generally a nonmetallic material, but is not limited thereto, and any material can be used as long as it can alleviate friction.
