Description

Technical Field

[0001] This application relates to the field of liquefied gas transportation technology, and in particular to a gas cylinder fixing structure and vehicle. Background Technology

[0002] With the development of new energy vehicle technologies, liquefied natural gas (LNG) as a fuel, as a branch of new energy technologies, is also constantly evolving. Installing gas cylinders to hold LNG is a necessary feature of gas-powered vehicles. For vehicles powered solely by a gas engine, the cylinders are typically fixed directly in the chassis, a common configuration. However, when vehicles require temporary installation of cylinders for long-distance travel, or for vehicles powered by a gas engine, the cylinder becomes a temporary or optional addition. In such cases, a suitable location on the vehicle is needed for temporary fixation and easy removal of the cylinder. Therefore, the traditional method of fixing the cylinder to the chassis, which is difficult to remove, is no longer suitable.

[0003] Taking trucks or pickup trucks as an example, the rear cargo box serves as a temporary location for mounting gas cylinders. While it can hold and secure the cylinders, conventional setups typically use ropes or standard mounting brackets to attach them to the cargo box floor, making both the mounting and dismounting processes cumbersome. Therefore, it is necessary to develop a structural solution that simplifies the mounting and dismounting of gas cylinders within the cargo box. Utility Model Content

[0004] In view of this, this application aims to provide a gas cylinder fixing structure to offer a structural solution suitable for fixing gas cylinders to vehicles that is easy to install and remove.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A gas cylinder fixing structure is provided for fixing a gas cylinder to a load-bearing plate of a vehicle. The gas cylinder fixing structure includes a base assembly detachably mounted on the load-bearing plate and a fastening unit disposed on the base assembly. The top of the base assembly is provided with a support plate. The fastening unit includes pull plates at both ends respectively connected to the two ends of the support plate. The gas cylinder is fastened to the support plate by the pull plates. The pull plates are composed of multiple arc-shaped segmented pull plates connected together, and the arc angle of each segmented pull plate is less than 180°. The segmented pull plates are fastened together by connecting components.

[0006] Furthermore, the segmented pull plate includes a first segmented pull plate and a second segmented pull plate; the arc angle of the first segmented pull plate is 150° to 180°, and the arc angle of the support plate (30) is 100° to 140°.

[0007] Furthermore, the end of the pallet is bent into a connecting platform, and the end of the segmented pull plate is bent into a connecting end plate. The connecting end plate includes a pallet connecting end plate for connecting the connecting platform and a segmented connecting end plate for connecting adjacent segmented pull plates. The pallet connecting end plate is attached to the connecting platform and fastened with bolts, and an anti-rotation structure is provided between the pallet connecting end plate and the connecting platform to prevent the pallet connecting end plate from rotating relative to the connecting platform.

[0008] Furthermore, the anti-rotation structure includes an anti-rotation hole formed on the connecting platform and an anti-rotation pin provided on the pallet connecting end plate; when the pallet connecting end plate is attached to the connecting platform, the anti-rotation pin is inserted into the anti-rotation hole.

[0009] Furthermore, it also includes a protective cover covering the outside of the gas cylinder; the pull plate is provided with a protective cover mounting bracket, the middle part of the protective cover is fixed to the protective cover mounting bracket, and the bottom of the protective cover is connected to the connecting platform.

[0010] Furthermore, the two segmented connecting end plates between adjacent segmented pull plates are arranged opposite to each other and are spaced apart; the connecting assembly includes a pad placed on the opposite side of the segmented connecting end plates, a connecting bolt passing through the two pads and the two segmented connecting end plates, and a fastening nut screwed onto the connecting bolt.

[0011] Furthermore, the tightening unit also includes a buffer pad placed on the side of the support plate and the pull plate facing the gas cylinder.

[0012] Furthermore, the base assembly includes two support plates arranged opposite to each other, each support plate having a base plate connected to the load-bearing plate body, and an upright plate extending upward from the side portion of the base plate; the tray rests on the two upright plates.

[0013] Furthermore, it also includes a bottom plate reinforcing plate arranged at the bottom of the load-bearing plate corresponding to the base plate, and the base plate, the load-bearing plate and the bottom plate reinforcing plate are fastened together by through bolts.

[0014] Compared with related technologies, this application has the following advantages: (1) The gas cylinder fixing structure of this application provides a detachable base assembly on the load-bearing plate of the vehicle, with a support plate on the top of the base assembly, which ensures that the gas cylinder can be smoothly placed on the support plate; then, the gas cylinder can be reliably fixed to the base assembly using a clamping unit. The pull plate in the clamping unit adopts a multi-segment structure, which avoids the situation where the pull plate with an excessive arc angle is difficult to hold the gas cylinder smoothly due to the small opening size. Multiple segmented pull plates are connected into one piece by connecting components and connected to the end of the support plate, so that the gas cylinder can be smoothly fixed to the base assembly, thereby providing a structural solution suitable for fixing gas cylinders to vehicles that is easy to install and remove.

[0015] (2) Setting the number of segmented pull plates to two segments helps reduce the workload of connecting the segments; at the same time, controlling the arc angle of the first segment pull plate between 150° and 180° ensures that it has sufficient span to complete most of the constraint dimensions of the gas cylinder, and the remaining constraint dimensions are completed by the second segment pull plate, which can keep the second segment pull plate within a shorter size range; in this way, the first segment pull plate can be installed first and the second segment pull plate can be installed last. The shorter second segment pull plate is easier to connect and assemble, which makes the overall assembly of the pull plates and the configuration of the number of parts more reasonable, which is conducive to further improving the convenience of the overall fixing operation of the gas cylinder. Reasonably controlling the arc angle of the upper support plate of the base assembly can ensure that the overall height of the base assembly is low.

[0016] (3) By setting a connecting platform at the end of the pallet and a connecting end plate at the end of the segmented pull plate, the pallet connecting end plate in the connecting end plate can be tightly fitted onto the connecting platform. The two connected segmented pull plates can also be reliably connected by the segmented connecting end plate, thereby effectively improving the connection stability between the segmented pull plate and the pallet, as well as between adjacent segmented pull plates. Furthermore, an anti-rotation structure is set between the pallet connecting end plate and the connecting platform. When the pallet connecting end plate is tightened onto the connecting platform with bolts, it can effectively prevent the pallet connecting end plate from rotating on the connecting platform, thereby ensuring the accuracy of the posture of the entire pull plate.

[0017] (4) The anti-rotation structure adopts an anti-rotation hole opened on the connecting platform and an anti-rotation pin set on the connecting end plate of the pallet. It is a plug-in fit. It has the characteristics of simple structure and easy processing. When the anti-rotation pin is inserted into the anti-rotation hole, since there is a gap between the plug-in part of the anti-rotation pin and the anti-rotation hole and the bolt used to fasten the connecting end plate of the pallet, the two connection points can restrict the rotation of the connecting end plate of the pallet, thereby ensuring the good anti-rotation effect of the anti-rotation structure.

[0018] (5) By setting a protective cover mounting bracket on the pull plate, the protective cover can be installed on the protective cover mounting bracket; at the same time, the bottom of the protective cover is fixed on the connecting platform, so that the protective cover can be firmly placed on the outside of the gas cylinder, thus forming good protection for the gas cylinder; it can effectively prevent flying stones and other objects from directly hitting the gas cylinder, which is conducive to ensuring the safety of the gas cylinder.

[0019] (6) The two adjacent segmented pull plates are connected by two opposite segmented connecting end plates. By leaving a certain gap between the two segmented connecting end plates and cooperating with the connecting bolts in the connecting assembly, it can be ensured that the entire pull plate can hold the gas cylinder tightly. By tightening the fastening nuts on the connecting bolts, the first and second segmented pull plates are gradually tightened during the tightening process, and the distance between the opposite segmented connecting end plates is brought closer. The clamping force of the pull plate on the gas cylinder can be flexibly controlled, thereby ensuring the reliability of the gas cylinder fixing structure for fixing the gas cylinder.

[0020] (7) By setting buffer pads on the inside of the tray and pull plate, direct contact between the plate and the surface of the gas cylinder is avoided, so as to form good buffer and protection and avoid damage to the surface of the gas cylinder.

[0021] (8) The base assembly adopts two L-shaped support plates to support the pallet, realizing the individual processing structure of the three separate parts. Each individual component has a simple structure, which is convenient for rapid stamping and forming using sheet metal, making the overall efficiency of the structure higher. The L-shaped support plate can be firmly fixed to the load-bearing plate using its bottom base plate, while the vertically arranged upright plate can form a good support effect between the load-bearing plate and the pallet.

[0022] (9) Based on the above-mentioned substrate being attached to the upper surface of the load-bearing plate, a bottom plate reinforcement plate is added to the bottom of the load-bearing plate, so that the substrate and the bottom plate reinforcement plate can clamp the load-bearing plate tightly from top to bottom, increasing the structural stability of the bottom of the entire base assembly; with the three-layer plate being integrated and fixed, the support foundation of the entire gas cylinder fixing structure is more reliable.

[0023] Another object of this application is to provide a vehicle equipped with the gas cylinder fixing structure described in this application. The vehicle of this application possesses the technical advantages of the aforementioned gas cylinder fixing structure. Attached Figure Description

[0031] Installing gas cylinders to hold liquefied natural gas is a necessary feature of natural gas vehicles. For vehicles powered solely by a natural gas engine, the cylinders are typically fixed directly to the chassis, a common configuration. However, when a vehicle needs to temporarily install a cylinder for long-distance travel, or for vehicles that use a natural gas engine as one of their power sources, the cylinder becomes a temporary addition or optional feature. In such cases, a suitable location on the vehicle is needed for temporary fixation and easy removal of the cylinder. This renders the traditional, fixed-to-the-chassis method, which is difficult to remove, unsuitable. For example, in trucks or pickups, the cargo bed serves as a temporary location for cylinders. While the cargo bed can hold and secure the cylinder, conventional methods like ropes or standard brackets are used to attach it to the cargo bed floor, making both fixing and removal cumbersome.

[0032] It should be noted that, in addition to the cargo box floor as the mounting base for fixing gas cylinders, any mounting plate on the vehicle with a certain load-bearing capacity can also be used as the mounting base for fixing gas cylinders.

[0033] In view of the above-mentioned problems in the related technologies, this application innovatively proposes a brand-new gas cylinder fixing structure, which is suitable for fixing the gas cylinder 6 to the vehicle and is easy to disassemble and assemble.

[0034] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0035] An embodiment of the first aspect of this application provides a gas cylinder fixing structure for fixing a gas cylinder 6 to a load-bearing plate 1 of a vehicle; one exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0036] Overall, the gas cylinder fixing structure includes a base assembly 3 detachably mounted on a load-bearing plate 1, and a fastening unit 4 disposed on the base assembly 3. The base assembly 3 has a support plate 30 at its top, and the fastening unit 4 includes pull plates 40 whose two ends are respectively connected to the two ends of the support plate 30. The gas cylinder 6 is fastened to the support plate 30 by the pull plates 40. The pull plates 40 are composed of multiple arc-shaped segmented pull plates connected together, and the arc angle of each segmented pull plate is less than 180°. The segmented pull plates are fastened together by connecting components 41.

[0037] Based on the overall design concept described above, a detachable base assembly 3 is installed on the vehicle's load-bearing plate 1, with a support plate 30 on top of the base assembly 3, ensuring that the gas cylinder 6 can be smoothly placed on the support plate 30. Then, the clamping unit 4 can reliably fix the gas cylinder 6 to the base assembly 3. The pull plate 40 in the clamping unit 4 adopts a multi-segment structure, avoiding the situation where a pull plate 40 with an excessively large arc angle would be difficult to clamp onto the gas cylinder 6 due to its small opening size. Multiple segmented pull plates are connected as one unit by connecting components 41 and connected to the end of the support plate 30, thus smoothly fixing the gas cylinder 6 to the base assembly 3. This provides a structural solution suitable for fixing the gas cylinder 6 to a vehicle that is easy to install and remove.

[0038] It should be noted that, based on the above-mentioned overall design concept, the technical solution of this application can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the aforementioned base assembly 3 can be a single-unit structure, or it can be formed by separately processing multiple parts and then welding them together to form the base assembly 3; the specific arrangement sequence and assembly method of the base assembly 3, the clamping unit 4, and their placement on the load-bearing plate 1 can also be flexibly adjusted. For parts required for the implementation of the overall solution but not covered in the above-mentioned overall setup, reasonable and flexible designs can be made by referring to mature setup methods in the field and the actual situation during implementation, which will not be elaborated here. The specific implementation scheme described below in this embodiment is only one of the many solutions that can be formed by the various combinations and variations mentioned above. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the various solutions that can be formed by the combinations and variations of the above-mentioned specific forms, as well as the specific implementation scheme of this embodiment, are all within the protection scope of this application.

[0039] The following will provide a detailed description of the solution proposed in this application. To facilitate a better understanding of the solution, it is necessary to provide a general overview of the practical application of the gas cylinder fixing structure before proceeding with the detailed description. This gas cylinder fixing structure is applicable to the installation of gas cylinders on various types of vehicles, as well as to equipment or facilities requiring the fixing of gas cylinders 6. When applied to vehicles, any fixing plate with a certain load-bearing capacity on the vehicle can be used as the installation base for fixing the gas cylinder. However, considering that the rear cargo boxes of pickup trucks or small vans are well-known, this embodiment will use the installation application on a pickup truck as an example. The load-bearing plate 1 shown in the figure is the floor plate of the rear cargo box of the pickup truck.

[0040] Continue as Figure 3 , Figure 4 As shown, as a preferred exemplary implementation among various feasible solutions, the segmented pull plate of this embodiment includes a first segmented pull plate 40a and a second segmented pull plate 40b; wherein, the arc angle of the first segmented pull plate 40a is 150° to 180°; the arc angle of the support plate 30 is preferably set between 100° and 140°. By reasonably controlling the arc angle of the support plate 30 on the base assembly 3, it can be ensured that the base assembly as a whole has a low height dimension.

[0041] Setting the number of segmented pull plates to two segments helps reduce the workload of connecting the segments. At the same time, controlling the arc angle of the first segment pull plate 40a between 150° and 180° ensures that it has sufficient span to complete most of the constraint dimensions of the gas cylinder 6. The remaining constraint dimensions are completed by the second segment pull plate 40b, which can be kept within a shorter size range. In this way, the first segment pull plate 40a can be installed first, and the second segment pull plate 40b can be installed last. The shorter second segment pull plate 40b is easier to connect and assemble. This makes the overall assembly and part number configuration of the pull plate 40 more reasonable, which helps to further improve the convenience of the overall fixing operation of the gas cylinder 6.

[0042] Simultaneously, a connecting platform 300 can be formed by bending the end of the pallet 30, and a connecting end plate can be formed by bending the end of the segmented pull plates accordingly. Specifically, the connecting end plate in this embodiment includes a pallet connecting end plate 400 for connecting the connecting platform 300, and a segmented connecting end plate 407 for connecting adjacent segmented pull plates. During installation, the pallet connecting end plate 400 is attached to the connecting platform 300 and fastened with bolts, and an anti-rotation structure is provided between the pallet connecting end plate 400 and the connecting platform 300 to prevent the pallet connecting end plate 400 from rotating relative to the connecting platform 300.

[0043] By providing a connecting platform 300 at the end of the pallet 30 and a connecting end plate at the end of the segmented pull plate, the pallet connecting end plate 400 in the connecting end plate can fit tightly against the connecting platform 300. Two connected segmented pull plates can also be reliably connected via the segmented connecting end plate 407, thereby effectively improving the connection stability between the segmented pull plate and the pallet 30, as well as between adjacent segmented pull plates. Furthermore, an anti-rotation structure is provided between the pallet connecting end plate 400 and the connecting platform 300. When the pallet connecting end plate 400 is tightened onto the connecting platform 300 using bolts, it effectively prevents the pallet connecting end plate 400 from rotating on the connecting platform 300, thus ensuring the accuracy of the posture of the entire pull plate 40.

[0044] Regarding the above-mentioned configuration, in specific implementation and application, mature methods or products in this field can be used, and adjustments can be made based on the convenience, rationality, and applicability of implementation. In this embodiment, a base connection hole 402 is provided on the pallet connecting end plate 400, and a pull plate connection hole 302 is correspondingly provided on the connecting platform 300. When installing the pull plate 40 onto the pallet 30, first align the anti-rotation structure, then align the base connection hole 402 and the pull plate connection hole 302, and then use the first mounting bolt 404 to pass through the base connection hole 402 and screw it into the pull plate connection hole 302, and tighten it, so that the pallet connecting end plate 400 can be installed and secured on the connecting platform 300.

[0045] There are, of course, various technical solutions to choose from for the specific design of the anti-rotation structure. For example, a connecting bolt can be added between the pallet connecting end plate 400 and the connecting platform 300, and the two bolts can be spaced apart in conjunction with the first mounting bolt 404 mentioned above, which can also ensure that the pallet connecting end plate 400 will not rotate relative to the connecting platform 300. However, in order to obtain a better technical effect, the following configuration is preferred.

[0046] Specifically, such as Figure 4As shown, as a preferred exemplary implementation among various feasible solutions, the anti-rotation structure of this embodiment includes an anti-rotation hole 301 formed on the connecting platform 300 and an anti-rotation pin 401 provided on the pallet connecting end plate 400; when the pallet connecting end plate 400 is attached to the connecting platform 300, the anti-rotation pin 401 is inserted into the anti-rotation hole 301. The anti-rotation structure adopts an insertion-fit form of the anti-rotation hole 301 formed on the connecting platform 300 and the anti-rotation pin 401 provided on the pallet connecting end plate 400. It has the characteristics of simple structure and easy processing. When the anti-rotation pin 401 is inserted into the anti-rotation hole 301, since there is a gap between the insertion part of the anti-rotation pin 401 and the anti-rotation hole 301 and the bolt used to fasten the pallet connecting end plate 400, the two connection points can restrict the rotation of the pallet connecting end plate 400, thereby ensuring a good anti-rotation effect of the anti-rotation structure.

[0047] Continue to refer to Figure 2 and combined Figure 3 As shown, as a preferred exemplary implementation among various feasible solutions, the gas cylinder fixing structure of this embodiment also includes a protective cover 5 covering the outside of the gas cylinder 6; a protective cover mounting bracket 42 is provided on the pull plate 40, the middle part of the protective cover 5 is fixed to the protective cover mounting bracket 42, and the bottom of the protective cover 5 is connected to the connecting platform 300. By providing a protective cover mounting bracket 42 on the pull plate 40, and then installing the protective cover 5 on the protective cover mounting bracket 42; at the same time, fixing the bottom of the protective cover 5 to the connecting platform 300, the protective cover 5 can be firmly covered on the outside of the gas cylinder 6, thereby forming good protection for the gas cylinder 6; it can effectively prevent flying stones and other objects from directly hitting the gas cylinder 6, which is conducive to ensuring the safety of the gas cylinder.

[0048] Regarding the above-mentioned configuration, in specific implementation and application, a protective cover mounting hole 303 can be provided on the connecting platform 300, and a protruding fixed support leg 52 can be provided at the bottom of the protective cover 5. The fixed support leg 52 can be securely fixed to the support plate 30 by screwing a second mounting bolt 520 through the fixed support leg 52 into the protective cover mounting hole 303 on the connecting platform 300. Corresponding to the protective cover mounting bracket 42 on the pull plate 40, a mounting groove 51 can be provided on the protective cover 5. During installation, the protective cover mounting bracket 42 is inserted into the mounting groove 51 to achieve reliable positioning and restraint. Then, a third mounting bolt 510 passes through the plate at the bottom of the mounting groove 51 and is screwed onto the protective cover mounting bracket 42, thus securely fixing the middle part of the protective cover 5 to the pull plate 40. In this way, the entire protective cover 5 can securely shield the outside of the gas cylinder 6, achieving a good protective effect. In addition, to facilitate users to observe the condition of the gas cylinder 6 in a timely manner, a monitoring window 50 can be opened in the middle of the protective cover 5.

[0049] There are, of course, various technical solutions to choose from for the specific arrangement of the pad 410; for example, it can be a flat plate or a plate with a bent structure; in this embodiment, a bent structure pad 410 is preferred, with the two parts of the pad 410 respectively placed on the main body of the segmented connecting end plate 407 and the segmented pull plate, ensuring the positional stability of the pad 410 on the segmented connecting end plate 407. However, to obtain a better technical effect, the following arrangement is preferred.

[0050] Specifically, continue as Figure 3 , Figure 4 As shown, as a preferred exemplary embodiment among various feasible solutions, the two segmented connecting end plates 407 between adjacent segmented pull plates are arranged opposite each other, and there is a gap between them; the connecting assembly 41 includes a pad 410 placed on the opposite side of the segmented connecting end plate 407, a connecting bolt 411 passing through the two pads 410 and the two segmented connecting end plates 407, and a fastening nut 412 screwed onto the connecting bolt 411. The two adjacent segmented pull plates are connected by the two opposing segmented connecting end plates 407. By leaving a certain gap between the two segmented connecting end plates 407, and cooperating with the connecting bolt 411 in the connecting assembly 41, it can be ensured that the entire pull plate 40 can tightly hold the gas cylinder 6. By tightening the fastening nut 412 on the connecting bolt 411, the first segment pull plate 40a and the second segment pull plate 40b are gradually tightened during the tightening process. The distance between the two opposite segment connecting end plates 407 is brought closer, which allows for flexible control of the clamping force of the pull plate 40 on the gas cylinder 6, thereby ensuring the reliability of the gas cylinder fixing structure in fixing the gas cylinder 6.

[0051] In addition, to ensure the reliability of the connection of the connecting assembly 41, two fastening nuts 412 can be provided on the connecting bolt 411. Tightening the two fastening nuts 412 simultaneously ensures locking and prevents the nuts from loosening. In specific operation, the connecting bolt 411 is sequentially inserted into the segmented connecting holes 403 on the two segmented connecting end plates 407 through the segmented connecting holes 403 opened in the middle of the segmented connecting end plate 407, and then the fastening nuts 412 are screwed onto the connecting bolts 411, thus completing the connection operation between two adjacent segmented pull plates. It should also be noted that, in order to improve the structural strength of each segmented pull plate, some reinforcing protrusions or reinforcing grooves can be stamped on the segmented pull plates in one go. In this embodiment, a first reinforcing rib 406 is stamped on the main body of the segmented pull plate, and the first reinforcing rib 406 extends along the length direction of the segmented pull plate. A first reinforcing protrusion 405 is also formed at the connection position between the main body of the segmented pull plate and the connecting end plate to improve the structural stability between the main body and the connecting end plate.

[0052] Furthermore, as a preferred exemplary implementation among various feasible solutions, the tightening unit 4 of this embodiment also includes a buffer pad 43 placed on the side of the support plate 30 and the pull plate 40 facing the gas cylinder 6. By providing the buffer pad 43 on the inner side of the support plate 30 and the pull plate 40, direct contact between the plate and the surface of the gas cylinder 6 is avoided, thereby forming good buffering and protection and preventing damage to the surface of the gas cylinder 6.

[0053] Continue as Figure 4 As shown, as a preferred exemplary embodiment among various feasible solutions, the base assembly 3 of this embodiment includes two support plates 31 arranged opposite to each other. Each support plate 31 has a base plate 310 connected to the load-bearing plate 1, and vertical plates 311 extending upward from the side of the base plate 310. The support plate 30 is placed on the two vertical plates 311. The base assembly 3 uses two L-shaped support plates 31 to support the support plate 30, realizing the individual processing structure of the three separate components. Each individual component has a simple structure, facilitating rapid stamping using sheet metal, thus improving the overall efficiency of the structure. The L-shaped support plate 31, with its base plate 310 at its bottom, can be firmly fixed to the load-bearing plate 1, while the vertically arranged vertical plates 311 provide good support between the load-bearing plate 1 and the support plate 30.

[0054] In practical implementation and application, to improve the overall structural strength of the support plate 31, a second reinforcing rib 304 can be provided on the base plate 310, and a second reinforcing protrusion 313 can be provided on the upright plate 311, thereby improving the structural stability of the entire support plate 31 at key locations. In addition, weight-reducing holes 314 can be provided on the support plate 31 at locations that do not significantly affect the structural strength, in order to reduce the overall weight of the dissipation device.

[0055] In addition, continue as Figures 5 to 8 As shown, the gas cylinder fixing structure of this embodiment also includes a bottom plate reinforcing plate 2 arranged at the bottom of the load-bearing plate 1 corresponding to the base plate 310. The base plate 310, the load-bearing plate 1, and the bottom plate reinforcing plate 2 are fastened together by through bolts. Based on the above-mentioned situation where the base plate 310 is attached to the upper surface of the load-bearing plate 1, the bottom plate reinforcing plate 2 is added to the bottom of the load-bearing plate 1, so that the base plate 310 and the bottom plate reinforcing plate 2 can clamp the load-bearing plate 1 from top to bottom, increasing the structural stability of the bottom of the entire base assembly 3; with the three-layer plate being integrally fixed, the supporting foundation of the entire gas cylinder fixing structure is more reliable.

[0056] Regarding the above-mentioned configuration, in the specific implementation and application process, mature methods or products in this field can be used, and adjustments can be made based on factors such as ease of implementation, rationality, and applicability. For example, the base plate reinforcing plate 2 mentioned above can be reinforced using a flat plate.

[0057] However, in this embodiment, considering the structural feature of the load-bearing plate 1 which is usually stamped with reinforcing grooves 10 arranged along the length of the vehicle, the bottom plate reinforcing plate 2 of this embodiment should be set to conform to the wavy structure of the load-bearing plate 1. Therefore, from the bottom of the vehicle, the bottom plate reinforcing plate 2 also has a conforming protrusion 20 formed by conforming to the shape. Considering that a crossbeam will be installed at the bottom of the vehicle, that is, the bottom of the load-bearing plate 1, in order to avoid increasing the height of the bottom of the vehicle, the bottom plate reinforcing plate 2 of this embodiment is provided with a clearance groove 200 corresponding to the crossbeam, so that the crossbeam can be set in the clearance groove 200, and the installation of the crossbeam is not affected by the setting of the bottom plate reinforcing plate 2.

[0058] For the connection between the base plate 310 and the bottom plate reinforcing plate 2, multiple through holes 21 can be provided on the bottom plate reinforcing plate 2, and a bottom plate connection hole 312 can be provided on the base plate 310. Multiple sets of fourth mounting bolts 32 and square nuts 320 are used to fasten the three-layer plate. The fourth mounting bolts 32 pass sequentially from the top of the base plate 310 through the bottom plate connection hole 312, the through hole on the load-bearing plate 1, and the through holes 21, and are screwed to the square nuts 320 located below the bottom plate reinforcing plate 2, thus completing the fastening of the three-layer plate. The square nuts 320 are used because they can be precisely confined between the two conformal protrusions 20, effectively preventing the square nuts 320 from loosening.

[0059] In summary, the gas cylinder fixing structure of this embodiment, by setting a detachable base assembly 3 on the load-bearing plate 1 of the vehicle, and setting a support plate 30 on the top of the base assembly 3, ensures that the gas cylinder 6 can be smoothly placed on the support plate 30; then, the tightening unit 4 can reliably fix the gas cylinder 6 to the base assembly 3. The pull plate 40 in the tightening unit 4 adopts a multi-segment structure, avoiding the situation where the pull plate 40 with an excessive arc angle is difficult to tighten smoothly on the gas cylinder 6 due to the small opening size. Multiple segmented pull plates are connected into one piece by the connecting component 41 and connected to the end of the support plate 30, so that the gas cylinder 6 can be smoothly fixed to the base assembly 3, thereby providing a structural solution suitable for fixing the gas cylinder 6 to the vehicle that is easy to install and remove.

[0060] An embodiment of the second aspect of this application provides a vehicle equipped with the gas cylinder fixing structure provided in Embodiment 1.

[0061] To address the need for additional gas cylinders 6 in some vehicle models, a bottom plate reinforcement plate 2 with an M-shaped cross-section is added to the bottom of the load-bearing plate 1. An obstacle avoidance groove 200 is provided on the bottom plate reinforcement plate 2 to effectively prevent the installation of the vehicle body crossbeam. Multiple through holes 21 arranged on the bottom plate reinforcement plate 2 provide ample mounting points for the base assembly 3 above the load-bearing plate 1.

[0062] The base assembly 3 adopts a separate L-shaped support plate 31 and a support plate 30 welded together. The support plate 31 features weight-reducing holes 314 and a second reinforcing protrusion 313, which achieve weight reduction and structural reinforcement. The support plate 31 and the support plate 30 are welded together using MIG welding to improve pressure resistance. The symmetrically arranged support plates 31 are designed as universal parts with identical structures, facilitating maintenance and replacement. The base assembly 3 uses a separate processing and welding method, which is simpler than a one-piece Z-shaped support structure mold, reducing mold investment costs. The bottom of the support plate 31 is screwed to the load-bearing plate 1 and the base plate reinforcing plate 2, while the top is welded to the support plate 30 using MIG welding, forming a stable support structure.

[0063] The pull plate 40 adopts a two-section pull plate installation structure, which not only meets the operational requirements of employees but also maximizes the utilization of the internal space of the vehicle. Each section of the pull plate 40 and the support plate 30 are designed in an arc shape. An anti-rotation structure is installed between the support plate connecting end plate 400 and the connecting platform 300 to ensure the reliability of the connection between the pull plate 40 and the support plate 30. The anti-rotation structure can be configured with the following specific dimensions: a 10mm×5mm×2mm anti-rotation pin 401 is provided at the end of the support plate connecting end plate 400; a 15mm×9mm anti-rotation hole 301 is provided on the connecting platform 300. When the support plate connecting end plate 400 is installed onto the connecting platform 300, the anti-rotation pin 401 is positioned within the anti-rotation hole 301. When the support plate connecting end plate 400 rotates relative to the connecting platform 300, interference occurs between the two, achieving the anti-rotation effect.

[0064] Obviously, to ensure the reliable fixation of the gas cylinder 6, multiple sets of base assemblies 3 and fastening units 4 should be spaced apart in the width direction of the vehicle body. As shown in the accompanying drawings of this embodiment, two sets of base assemblies 3 and fastening units 4 are provided at the front of the load-bearing plate 1. These two sets of base assemblies 3 and fastening units 4 are spaced apart in the width direction of the vehicle body, thereby effectively fixing the gas cylinder 6 to the vehicle.

[0065] In addition, the gas cylinder 6 is protected by installing a C-shaped protective cover 5 on the pull plate 40 and the support plate 30. The monitoring window 50 on the protective cover 5 makes it easy to observe the information of the gas cylinder 6. At the same time, the protective cover 5 is designed to be easy to disassemble, which helps users to remove and replace or add metal storage devices such as a car trunk liner in the future.

[0066] Overall, the gas cylinder fixing structure of this application adopts a base assembly 3 that is easy to disassemble and a two-section pull plate 40 installation structure. Compared with the one-piece pull plate structure, it is not only easier to disassemble and assemble, but also increases the usable space inside the vehicle body by about 15%. The bolt installation in the same direction ensures the balanced force on the bolts and the installation is firm, which strengthens the tensile and bending strength of the installation structure. The easy removal of the protective cover 5 is conducive to the addition of metal body liner, etc., which greatly improves the power configuration of pickup trucks and other models, meets the needs of customers for special power forms, and helps to enhance the user appeal of the product.
