[0030] like Figures 1 to 6 As shown, the gas cylinder support assembly of the first embodiment includes: a support structure 10 and an elastic buffer structure 20. The support structure 10 includes a base 11 and a pressure cover 12, the base 11 is provided with a plurality of arc-shaped receiving grooves 111 spaced apart along a first direction X, the pressure cover 12 is provided with a plurality of arc-shaped pressure grooves 121 spaced apart along a first direction, the plurality of arc-shaped receiving grooves 111 and the plurality of arc-shaped pressure grooves 121 are provided one-to-one to form a receiving space, and the gas cylinder is placed in the receiving space formed by the arc-shaped receiving grooves 111 and the arc-shaped pressure grooves 121. The two ends of the elastic buffer structure 20 are respectively connected between adjacent arc-shaped pressure grooves 121 and adjacent arc-shaped receiving grooves 111.

[0031] By applying the technical solution of this embodiment, the gas cylinder 100 is placed in the arc-shaped receiving groove 111 of the base 11, and is pressed by the arc-shaped pressing groove 121. The same base 11 is provided with multiple arc-shaped receiving grooves 111, which can improve the utilization efficiency of the bracket assembly and save space. The two ends of the elastic buffer structure 20 are respectively connected between the adjacent arc-shaped pressing grooves 121 and the adjacent arc-shaped receiving grooves 111. The elastic buffer structure 20 can play a role in buffering and shock absorption. For example, when the gas cylinder 100 is subjected to temperature changes, thermal expansion and contraction will occur. The elastic buffer structure 20 not only provides pre-tightening force, but also can follow the thermal expansion and contraction of the gas cylinder to compensate for the adjustment of the spatial structure caused by the deformation, thereby avoiding the safety hazards caused by the thermal expansion and contraction of the gas cylinder 100. At the same time, the elastic buffer structure 20 is arranged between adjacent gas cylinders 100, which greatly reduces the number of elastic buffer structures 20, saves costs, and reduces the weight of the gas cylinder bracket assembly. The technical solution of this embodiment effectively solves the problem of dangers caused by thermal expansion and contraction during the storage and transportation of gas cylinders in the prior art.

[0032] like Figure 3 , Figure 4 and Figure 6 As shown, in the technical solution of this embodiment, adjacent arc-shaped receiving grooves 111 are connected by a first connection portion, adjacent arc-shaped pressing grooves 121 are connected by a second connection portion, the first end of the elastic buffer structure 20 is connected to the first connection portion, and the second end of the elastic buffer structure 20 is connected to the second connection portion. The above-mentioned structural setting makes the structure of the pressure cover 12 equivalent to a cantilever beam structure, so that the adjustment of the space of the gas cylinder 100 can be achieved relatively easily. It should be noted that the diameter of the receiving space of the gas cylinder 100 formed by the arc-shaped receiving groove 111 and the arc-shaped pressing groove 121 is slightly larger than the diameter of the gas cylinder 100, and the remaining part can be filled with a wear-increasing buffer pad, which further increases the adjustable range of the space formed by the arc-shaped receiving groove 111 and the arc-shaped pressing groove 121. The wear-increasing buffer pad can be made of rubber, silicone, etc. Of course, the diameter of the accommodating space of the gas cylinder 100 formed by the arc-shaped accommodating groove 111 and the arc-shaped pressing groove 121 may also be equal to the diameter of the gas cylinder 100 , and its deformation is achieved through the deformation between the arc-shaped accommodating groove 111 and the arc-shaped pressing groove 121 .

[0033] like Figures 1 to 6 As shown, in the technical solution of this embodiment, the elastic buffer structure 20 includes a spring 21, a first screw 22, a second screw 23, a first nut and a second nut, the first connecting portion has a first through hole, the second connecting portion has a second through hole, the first screw 22 is fixedly connected to the first end of the spring 21, the second screw 23 is fixedly connected to the second end of the spring 21, the spring 21 is located between the first connecting portion and the second connecting portion, the first screw 22 passes through the first through hole to cooperate with the first nut, and the second screw 23 passes through the second through hole to cooperate with the second nut. The above structure is compact, easy to operate, and has low processing cost. It should be noted that the diameter of the first through hole is larger than the diameter of the first screw 22 and smaller than the diameter of the spring 21, so that the first through hole forms a limit through the first nut and the spring 21, and the first end of the first screw 22 and the spring 21 is provided with a limit plate, which can also achieve the role of limiting. The matching limit structure of the second through hole and the second screw 23 is similar to the above structure, and will not be repeated here. The axial extension direction of the spring 21 is the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0034] like Figures 1 to 4As shown, in the technical solution of this embodiment, there are two arc-shaped receiving grooves 111 (of course, there can also be three, four, etc., and this embodiment takes two as an example), and two elastic buffer structures 20 are arranged at intervals between adjacent arc-shaped receiving grooves 111. The two elastic buffer structures 20 are respectively arranged at the head position of the gas cylinder 100 close to the gas cylinder 100 and the tail position close to the gas cylinder 100. Such a structure greatly saves the number of elastic buffer structures 20 used, that is, the two elastic buffer structures 20 must first be located between adjacent arc-shaped receiving grooves 111, and then the two elastic buffer structures 20 must be located on both sides along the axis direction of the gas cylinder 100, and the two gas cylinders 100 can pass through the two elastic buffer structures 20. It should be noted that the base 11 and the gland 12 are both frame structures, and the arc-shaped receiving groove 111 has at least two reinforcing ribs, which are respectively located at the head and tail of the gas cylinder 100. For example: in order to reduce weight, the base 11 and the gland 12 are both set as a frame structure, and the reinforcing ribs can be connecting rods, and the two ends of the connecting rods are respectively connected to the two arc-shaped receiving grooves 111 of the corresponding base 11 on the same layer, which greatly improves the strength of the base 11 and the gland 12. If there are three reinforcing ribs in the arc-shaped receiving groove 111 (the reinforcing ribs here can still be connecting rods, and the two ends of the connecting rods are respectively connected to the corresponding arc-shaped receiving grooves 111), in addition to the head and tail of the gas cylinder 100, there is also the middle part of the gas cylinder 100, which can greatly save the weight of the gas cylinder bracket assembly. As other embodiments, the base 11 and the gland 12 can also use metal arc plates that match the length of the gas cylinder 100, and reinforcing ribs are added to the metal arc plates.

[0035] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the support structure 10 also includes a pin 13, the base 11 has a first pin hole on both sides, the pressure cover 12 has a second pin hole on both sides, and the pin 13 passes through the first pin hole and the second pin hole respectively. The above structure is easy to assemble and disassemble, and the processing cost is low. When in use, the base 11 is laid flat, the two gas cylinders 100 are placed in the arc-shaped receiving groove 111, and the elastic buffer structure 20 is installed. The elastic buffer structure 20 and the base 11 are assembled through the first screw 22 and the first nut, and then the pressure cover 12 is placed, and the four pins 13 are respectively installed at the four corners of the support structure, and then the elastic buffer structure 20 and the pressure cover 12 are installed, that is, the second screw 23 and the second nut are assembled.

[0036] In the technical solution of this embodiment, the support structure 10 also includes a wear-reducing buffer pad, and the arc-shaped receiving groove 111 and the arc-shaped pressing groove 121 are both provided with a wear-reducing buffer pad. The provision of the wear-reducing buffer pad makes it difficult for the gas cylinder 100 to escape along the axial direction of the gas cylinder 100, and on the other hand, the wear-reducing buffer pad can also play a role in buffering and shock absorption. In addition, the wear-reducing buffer pad can also play a role in increasing the deformation amount of the gas cylinder support assembly. In addition, the wear-reducing buffer pad can also play a role in reducing the contact wear between the gas cylinder 100 and the base 11 and the pressure cover 12.

[0037] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the lowest part of the base 11 has a first engaging convex-concave structure 112. The first engaging convex-concave structure 112 cooperates with the outside and is not easy to loosen.

[0038] like Figures 1 to 6 As shown, in the technical solution of this embodiment, the top surface of the pressure cover 12 has a second bite convex-concave structure 122, and the convex and concave of the first bite convex-concave structure 112 and the second bite convex-concave structure 122 are arranged correspondingly. The first bite convex-concave structure 112 and the second bite convex-concave structure 122 cooperate with each other, so that multiple gas cylinder support assemblies can be stacked, and the stacked multiple gas cylinder support assemblies are not easy to loosen due to the action of the bite teeth. It should be noted that the convexity of the first bite convex-concave structure 112 corresponds to the groove of the second bite convex-concave structure 122, and the convexity of the second bite convex-concave structure 122 corresponds to the groove of the first bite convex-concave structure 112. By setting the vertical distance between the convexity and the groove of the first bite convex-concave structure 112, it is realized that the stacked gas cylinder support assemblies are not easy to tip over. The first bite convex-concave structure 112 and the second bite convex-concave structure 122 are both arc-shaped convexities and arc-shaped grooves, so that when they are matched, stress and strain are not easy to concentrate, can resist large external forces, and have a long service life.

[0039] like Figure 3 As shown, in the technical solution of this embodiment, the first occlusal convex-concave structure 112 includes multiple rows of protrusions, and the protrusions in adjacent rows are staggered. The second occlusal convex-concave structure 122 includes multiple rows of protrusions, and the protrusions in adjacent rows are staggered. In this way, the force between the first occlusal convex-concave structure 112 and the second occlusal convex-concave structure 122 is relatively balanced, and the direction of the limit is relatively comprehensive. It should be noted that the first occlusal convex-concave structure 112 includes multiple columns of protrusions, and the multiple columns of protrusions are also staggered, and the second occlusal convex-concave structure 122 includes multiple columns of protrusions, and the multiple columns of protrusions are also staggered.

[0040] The difference between the technical solution of Example 2 and the technical solution of Example 1 is that when the gas cylinder bracket assemblies are stacked, the lowest point of the lowest base 11 is the placement plane, the upper part of the uppermost pressure cover 12 is the matching plane, and the remaining matching positions are still convex-concave structures. In this way, there is no need to process the placement plane of the base 11 into a convex-concave structure, nor is there any need to process the upper part of the pressure cover 12 into a convex-concave structure.

[0041] The present application also provides a gas cylinder support module, the gas cylinder support module includes multiple groups of gas cylinder support assemblies, the multiple groups of gas cylinder support assemblies are stacked, and the gas cylinder support assemblies are the above-mentioned gas cylinder support assemblies.

[0042] It can be seen from the above that the technical solution of the present application can be assembled as needed through modular design. The limiting engaging teeth (the first engaging convex-concave structure 112 and the second engaging convex-concave structure 122) can provide limiting effects in four directions. Two horizontally placed hydrogen bottles only need to use one spring or two springs to meet the travel required for the expansion of the hydrogen bottles. The small number of springs saves costs and improves the hydrogen storage density of the hydrogen storage system.

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
