[0002] When gas cylinders in the prior art are installed on an external carrier, a fixing structure is required. Taking the installation of gas cylinders capable of storing hydrogen in fuel cells on vehicles as an example, the existing gas cylinder fixing device mainly includes a fixing base and a gas cylinder strap. The fixing base is mainly welded to the vehicle body to bear the weight of the gas cylinder, and the gas cylinder strap is mainly used to tighten and position the cylinder body. This traditional gas cylinder fixing structure can fix most types of gas cylinders. However, for Type IV gas cylinders (non-metallic inner liner fiber fully wrapped gas cylinders), since the gas cylinder liner is made of plastic material, the liner will expand due to pressure, temperature and other reasons during the process of filling and deflating the gas cylinder, causing the outer diameter of the gas cylinder to change.

[0003] The traditional gas cylinder fixing structure cannot absorb the diameter change caused by the expansion of the gas cylinder, which makes it easy to damage the gas cylinder strap and the gas cylinder when the gas cylinder expands, thereby affecting the fixing effect of the gas cylinder strap on the gas cylinder, and then affecting the fixing effect of the gas cylinder on the external carrier, which is not conducive to the safety of the gas cylinder.

[0043] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0044] Example 1

[0045] This embodiment relates to a gas cylinder fixing structure to solve the problem in the prior art that the gas cylinder fixing structure cannot absorb the diameter change of the gas cylinder 100, thereby causing damage to the gas cylinder strap 1 and the gas cylinder 100.

[0046] Overall, the gas cylinder securing structure of this embodiment includes a first securing bracket 2 mounted on the first end of a gas cylinder strap 1, a first connector 3 connecting the second end of the gas cylinder strap 1 to the first securing bracket 2, and an elastic member 4 mounted on the first connector 3. The first and second ends are positioned opposite each other, with the first securing bracket 2 being used to connect to an external gas cylinder securing support, and the second end being movably sleeved onto the first connector 3. The elastic member 4 tends to maintain a predetermined gap between the second and first ends.

[0047] The gas cylinder fixing structure described in this embodiment is advantageous in fixing the gas cylinder strap 1 to the gas cylinder 100 by arranging a first fixing bracket 2 on the first end plate of the gas cylinder strap 1, and connecting the second end of the gas cylinder strap 1 to the first fixing bracket 2 by a first connecting member 3. In addition, an elastic member 4 is arranged to absorb the diameter change caused by the expansion of the gas cylinder 100, which is advantageous in preventing the gas cylinder 100 from expanding and damaging the gas cylinder strap 1 and the gas cylinder 100, thereby ensuring the fixing effect of the gas cylinder strap 1 on the gas cylinder 100 and the safety of the gas cylinder 100.

[0048] Based on the above overall introduction, an exemplary structure of the gas cylinder fixing structure in this embodiment is as follows: Figure 1 As shown in FIG, part of the structure of the gas cylinder strap 1 is as follows Figure 2 As shown in . In this embodiment, to facilitate the placement of the first fixing bracket 2, a first connecting portion 1021 is provided outwardly at the first end of the gas cylinder strap 1. The first fixing bracket 2 is specifically connected to the first connecting portion 1021. To facilitate the connection between the second end and the first fixing bracket 2, a first connecting piece 1011 is provided at the second end of the gas cylinder strap 1, corresponding to the first connecting portion 1021. The first connecting member 3 is connected to the first connecting piece 1011 and the first fixing bracket 2. A predetermined gap is maintained between the second end and the first end, that is, the predetermined gap is maintained between the first connecting portion 1021 and the first connecting piece 1011.

[0049] In specific implementation, the preset gap can usually be selected based on the specifications of the gas cylinder 100 and the structural characteristics of the gas cylinder strap 1 used, and it can generally enable the gas cylinder strap 1 to have a certain degree of tightness adaptability in fixing the gas cylinder 100, and is conducive to the compactness of the overall fixing structure.

[0050] The first connecting piece 1011 is generally L-shaped and comprises a first vertical portion connected to the gas cylinder strap 1, and a first transverse portion for connecting to the first connecting portion 1021. To further enhance the structural strength of the first connecting piece 1011, first flanges 104 are provided on both sides of the first transverse and longitudinal portions in the width direction, respectively. This structure is simple and easy to arrange and implement.

[0051] As a feasible embodiment, a limiting structure is provided on the first connecting member 3, and the elastic member 4 is limited between the second end and the limiting structure. The location of the elastic member 4 here facilitates the elastic member 4 to apply a force toward the first end to the second end, so that the second end tends to approach the first end, thereby maintaining a preset gap between the first end and the second end. Figure 1 As shown in , the first connecting member 3 can be a bolt in the prior art, and the rod of the bolt is passed through the first connecting piece 1011, the first fixing bracket 2 and the first connecting part 1021 and is threadedly connected to the nut.

[0052] In terms of specific structure, the limiting structure includes a limiting block 301 sleeved on the first connecting member 3, and the limiting block 301 is located on the side of the second end away from the first end, and the elastic member 4 is limited between the second end and the limiting block 301. The limiting block 301 is arranged on the rod body of the bolt and can abut against the head of the bolt. The structure of the limiting block 301 here is simple, which is convenient for arrangement and implementation on the first connecting member 3. As a preferred embodiment, the elastic member 4 of this embodiment includes a spring sleeved on the first connecting member 3. Among them, the spring is sleeved on the rod body of the bolt, and the two ends of the spring abut on the limiting block 301 and the first connecting piece 1011 respectively. The setting of the spring is not only conducive to arrangement and implementation, but also has a good use effect.

[0053] As a preferred embodiment, a receiving space 200 is formed in the first fixing bracket 2, and the second end, the first connecting member 3 and the elastic member 4 are arranged in the receiving space 200. The provision of the receiving space 200 here facilitates protection of the various components in the receiving space 200 by installing the bracket.

[0054] In terms of detailed structure, Figure 3 As shown in the figure, the first fixed bracket 2 includes a first bracket body 201 in a "U" shape, and first connecting arms 202 folded outward at both ends of the first bracket body 201. The first end portion and the first connecting member 3 are connected to the bottom of the first bracket body 201, and the inner side of the first bracket body 201 is surrounded to form a accommodating space 200. A first connecting portion is provided on the first fixed bracket 2, and is connected to the external gas cylinder fixing carrier through the first connecting portion. Specifically, a first connecting portion is provided at each end of the first connecting arm 202. Here, the arrangement of the first bracket body 201 in a "U" shape and the first connecting arm 202 makes the structure of the first fixed bracket 2 simple and the installation stability on the external gas cylinder fixing carrier good.

[0055] The first connection portion in this embodiment comprises a first connection hole 2021 provided on each first connection arm 202. This structure is simple, easy to form, and provides a good connection effect. Of course, the first connection portion may also employ other structural forms besides connection holes, as long as the first fixing bracket 2 can be mounted on the external gas cylinder fixing support.

[0056] In order to further improve the performance of the structure of the first fixing bracket 2, as Figure 3As shown in FIG, reinforcing ribs are provided on two opposing side walls of the first bracket body 201, each extending to intersect with the first connecting arm 202 on the same side. To distinguish them from the reinforcing ribs described below, the reinforcing ribs on the first fixed bracket 2 are referred to as first reinforcing ribs 203. The provision of the first reinforcing ribs 203 helps to improve the structural strength of the first bracket body 201. Furthermore, flanges are provided on both sides of the first bracket body 201 and each first connecting arm 202. To distinguish them from the other flanges in this embodiment, the flanges on the first fixed bracket 2 are referred to as second flanges 2011. The second flanges 2011 herein also help to improve the structural strength of the first fixed bracket 2, and their structure is simple and easy to form. Of course, providing the second flanges 2011 only on one side of the first bracket body 201 and each first connecting arm 202 is also feasible.

[0057] It should be noted that the gas cylinder 100 in this embodiment can be, for example, a Type IV gas cylinder 100 with a non-metallic inner liner and fully wrapped with fiber in the prior art, which can be used to store gases such as hydrogen. The external gas cylinder fixing carrier can be, for example, a carrier such as a vehicle body for fixing the gas cylinder 100.

[0058] In addition, the gas cylinder strap 1 of this embodiment can be an integrated structure, in which case the first end and the second end are respectively the two free ends of the gas cylinder strap 1. Of course, the gas cylinder strap 1 can also be formed by connecting two separate straps, in which case the same ends of the two straps can be connected by the gas cylinder fixing structure, or one end can be connected by the gas cylinder fixing structure and the other end can be connected by the connecting structure.

[0059] In this embodiment, in addition to locating the limit block 301 on the side of the second end away from the first end, the limit block 301 can also be set on the side of the first end away from the second end. At this time, the elastic member 4 is limited between the first end and the limit block 301, which is also conducive to maintaining a preset gap between the second end and the first end.

[0060] In the gas cylinder securing structure of this embodiment, the elastic member 4 applies a corresponding preload force to the first end portion, securing the gas cylinder strap 1 to the gas cylinder 100. The preload force here is the tightening force F1 applied by the gas cylinder 100 when the gas cylinder 100 is empty. When the gas cylinder 100 is filled with high-pressure gas, such as hydrogen, the pressure and temperature of the gas cylinder 100 increase, causing the gas cylinder 100 to expand radially, resulting in an increase in diameter. At this time, the force applied to the second end portion causes the second end portion to move away from the first end portion, compressing the spring and absorbing the change in diameter of the gas cylinder 100. This allows the gas cylinder strap 1 to maintain its tightening force on the gas cylinder 100, which is now F2. When the high-pressure hydrogen is released from the gas cylinder 100, the pressure and temperature of the gas cylinder 100 decrease, causing the gas cylinder 100 to contract, causing the diameter of the gas cylinder 100 to gradually return to its empty state. Simultaneously, the spring gradually releases the preload force F2 until it reaches the empty state preload force F1.

[0061] The gas cylinder securing structure of this embodiment optimizes the connection structure between the first end and the second end, thereby ensuring that the first securing bracket 2, the first connecting member 3, and the elastic member 4 cooperate to maintain the gas cylinder strap 1 in place on the gas cylinder 100 during the expansion process. This not only provides excellent fastening without damaging the gas cylinder strap 1 or the gas cylinder 100, but also offers the advantage of ease of deployment and implementation. Furthermore, this gas cylinder securing structure can be used to secure gas cylinders 100 to gas cylinders of varying diameters, thus offering excellent versatility.

[0062] Example 2

[0063] This embodiment relates to a gas cylinder fixing device, comprising a gas cylinder strap 1 consisting of a first strap 101 and a second strap 102 that are fastened together, a first fixing structure located at one end of the gas cylinder strap 1, and a second fixing structure located at the other end of the gas cylinder strap 1. The first fixing structure adopts the gas cylinder fixing structure described in Example 1, and the first strap 101 has a first end, and the second strap 102 has a second end. The second fixing structure connects the first strap 101 and the second strap 102 together, and the second fixing structure is provided with a second connection portion connected to an external gas cylinder fixing carrier. The structure of the gas cylinder fixing device in use is as follows: Figures 4 to 7 As shown in .

[0064] As a preferred embodiment, Figure 8 As shown in FIG, the second fixing structure includes a second fixing bracket 5 provided at the end of the first strap 101, and a second connecting member 6 connecting the end of the second strap 102 to the second fixing bracket 5; the second connecting portion is provided on the second fixing bracket 5. Here, the connection effect is good through the cooperation between the second fixing bracket 5 and the second connecting member 6.

[0065] In terms of specific structure, Figure 10As shown in FIG, to facilitate the installation of the second fixing bracket 5 on the first strap 101, a second connecting piece 1012 is provided at the other end of the first strap 101, relative to the first connecting piece 1011. The second connecting piece 1012 is L-shaped and has a second vertical portion and a second transverse portion. The second vertical portion is used to connect to the first strap 101, and the second transverse portion is used to connect to the second connecting member 6. A third flange 106 is provided on either side of the second transverse portion and the second vertical portion to enhance the structural strength of the second connecting piece 1012 and its stability during use.

[0066] Reference Figure 9 As shown in the figure, corresponding to the second transverse portion, a second connecting portion 1022 is provided at the end of the second strap 102, which is turned outward. The second connecting member 6 is connected between the second transverse portion, the second fixing bracket 5 and the second connecting portion 1022, so as to be used to connect the corresponding ends of the first strap 101, the second fixing bracket 5 and the second strap 102 together, and the second fixing bracket 5 in the connected state is clamped between the second transverse portion and the second connecting portion 1022, thereby having better connection stability.

[0067] As a preferred structural example of the second fixing bracket 5, Figure 11 As shown in , the second fixed bracket 5 includes a "U"-shaped second bracket body 501 and outward-folded second connecting arms 502 at both ends of the second bracket body 501. The ends of the second strap 102 and the second connecting member 6 are connected to the bottom of the second bracket body 501. A second connecting portion is provided at each end of the second connecting arm 502, and a reinforcing plate 504 is provided between at least one of the second connecting arms 502 and the second bracket body 501. The "U"-shaped second bracket body 501 and the outward-folded second connecting arms 502 here have the advantages of easy layout and implementation, as well as good connection stability. In addition, the reinforcement plate 504 provided between the second connecting arm 502 and the second bracket body 501 helps to improve the structural strength of the second fixed bracket 5.

[0068] In order to further improve the performance of the structure of the second fixing bracket 5, in this embodiment, Figure 11 As shown in the figure, second reinforcing ribs 505 are respectively provided at the corners of the second bracket body 501 and at the connections between the two opposite side walls and the corresponding second connecting arms 502. The cooperation of multiple second reinforcing ribs 505 is conducive to improving the structural strength of the second bracket body 501.

[0069] Continue to refer to Figure 11As shown in , the reinforcing plate 504 in this embodiment has a first part 5041 connected to the second connecting arm 502, and a second part 5043 connected to the side wall of the second bracket body 501 on the same side, and a middle part 5042 for connecting the first part 5041 and the second part 5043 together, and a triangular structure is formed between the middle part 5042, the second bracket body 501 and the second connecting arm 502. In this way, the high stability of the triangle can be utilized to improve the structural strength and stability of the second fixed bracket 5.

[0070] The second connection portion of this embodiment includes a second connection hole 5021 extending through the second connection arm 502 and the first portion 5041. The second connection member 6 includes a bolt extending through the second connection piece 1012, the second fixing bracket 5, and the second connection portion 1022, and a nut threadedly engaged with the bolt. This structure is simple, easy to install, and provides a good connection effect.

[0071] As a feasible arrangement, the distance between the first end of the first strap 101 and the external gas cylinder mounting support is greater than the distance between the second end thereof and the external gas cylinder mounting support. Therefore, the height of the first mounting bracket 2 is greater than the height of the second mounting bracket 5, thereby meeting the installation requirements of the gas cylinder 100 on the external gas cylinder mounting support. Of course, the heights of the first mounting bracket 2 and the second mounting bracket 5 can also be determined based on actual use, as long as the connection requirements are met.

[0072] In addition, if Figure 9 As shown in , in this embodiment, the first strap 101 is located above the gas cylinder 100, the second strap 102 is located below the gas cylinder 100, and a protective plate mounting seat 103 is provided on at least the second strap 102. The protective plate mounting seat 103 here is fixed to the second strap 102 by welding, and the protective plate mounting seat 103 is provided with mounting points for mounting a protective plate to facilitate the installation of the protective plate. The provision of the protective plate mounting seat 103 here is conducive to improving the structural integration of the gas cylinder strap 1 and the safety of the gas cylinder 100. In addition, a protective layer 105 is provided on the inner side of the first strap 101 and the second strap 102, respectively, to prevent the gas cylinder 100 from being lost by the gas cylinder strap 1. In a specific implementation, the protective layer 105 can be made of rubber.

[0073] When using the gas cylinder securing device of this embodiment, the first and second straps 101, 102 are first connected to the second fixing bracket 5 via the second connector 6. The other ends of the first and second straps 101, 102 are then connected to the elastic member 4 via the first connector 3, thereby securing the gas cylinder strap 1 to the gas cylinder 100. Finally, the first and second fixing brackets 2, 5 are mounted on an external gas cylinder securing support. For example, a single gas cylinder 100 can be secured to an external gas cylinder securing support using multiple gas cylinder securing devices.

[0074] In the gas cylinder fixing device described in this embodiment, the first strap 101 and the second strap 102 are fixed to the gas cylinder 100 through the above-mentioned first fixing structure and second fixing structure, which is beneficial to improving the fixing effect of the gas cylinder fixing device on the gas cylinder 100 and the safety of the gas cylinder 100.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
