Description

Technical Field

[0001] This utility model relates to the field of hydrogen storage technology, specifically to a hydrogen storage cylinder loading and unloading system for a hydrogen energy carrier. Background Technology

[0002] For example, the published patent CN214984810U states that "Currently, range-extended electric vehicles serve as a transitional model between traditional gasoline vehicles and pure electric vehicles, combining the advantages of both. However, traditional gasoline range extenders still emit carbon dioxide and harmful gases. Hydrogen is a clean energy source, and its combustion only produces heat and water. Range extenders using hydrogen as fuel best meet the definition of new energy vehicles. Currently, during long-distance driving, if the hydrogen in the storage tank runs out, it is difficult to replenish it in time, making it difficult to extend the range using hydrogen. Replacing the hydrogen storage tank is also extremely complicated and difficult to do halfway through a journey."

[0003] As described in the published patent CN218064416U, "An Installation Structure for a Hydrogen Storage Tank for a Hydrogen Energy Vehicle," with the continuous development and progress of technology, the demand for transportation is constantly increasing. With the increasing fuel consumption of gasoline-powered vehicles and the gradual depletion of non-renewable resources, the development of gasoline-powered vehicles is gradually reaching its limit. The development and research of new energy sources to replace traditional gasoline energy is necessary. Hydrogen energy vehicles are divided into two types: one is a hydrogen internal combustion engine vehicle, which uses an internal combustion engine to burn hydrogen to generate power to propel the vehicle; the other is a hydrogen fuel cell vehicle, which uses hydrogen or hydrogen-containing substances to react with oxygen in the air in a fuel cell to generate electricity to drive an electric motor, which then propels the vehicle. During the use of hydrogen energy vehicles, liquid hydrogen tanks are required for storing hydrogen. When installing and using liquid hydrogen tanks, they need to be stably installed on the hydrogen energy vehicle. In existing technologies, existing hydrogen fuel cell vehicles use bolt-fixed and installed liquid hydrogen tanks. During installation, multiple bolts need to be locked at various points. This multi-bolt locking structure greatly complicates the replacement and maintenance of liquid hydrogen tanks. Improving the ease of installation and disassembly of liquid hydrogen tanks is needed.

[0004] In summary, among the technologies related to hydrogen fuel cell vehicles and electric vehicles, the installation and removal of hydrogen storage cylinders presents a problem of inconvenience. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 A hydrogen storage cylinder loading and unloading system for a hydrogen energy vehicle includes a base plate 100, on which a mounting frame 101 is fixedly mounted. The mounting frame 101 includes a support 102 fixed longitudinally on the base plate 100. Several supports 102 are arranged side by side, and adjacent supports 102 cooperate to form a storage cylinder space 103. like Figure 1 As shown, during the process of installing the hydrogen storage cylinder 114 into the storage space 103, the support of the horizontal mounting shaft 106 and the rotation of the horizontal roller 107 enable the hydrogen storage cylinder 114 to slide better into the storage space 103. The guidance of the vertical mounting shaft 104 and the rotation of the vertical roller 105 make the installation of the hydrogen storage cylinder 114 more convenient. The end of the hydrogen storage cylinder 114 is limited by the limiting baffle 108. After the hydrogen storage cylinder 114 is installed into the storage space 103, the head of the hydrogen storage cylinder 114 is limited and locked by the limiting locking assembly 109. The hydrogen storage cylinder 114 loading and unloading system of this utility model hydrogen energy carrier is easy to operate, versatile, and easy to maintain; A vertical mounting shaft 104 is fixedly mounted on the support 102 along the vertical direction. Multiple vertical mounting shafts 104 are equidistantly mounted along the length direction of the support 102. A vertical roller component 105 is rotatably mounted on the vertical mounting shaft 104. A transverse mounting shaft 106 is fixed between adjacent brackets 102 along the transverse direction. Multiple transverse mounting shafts 106 are equidistantly mounted along the length direction of the bracket 102. A transverse roller 107 is rotatably mounted on the transverse mounting shaft 106. One end of the bracket 102 is fixedly provided with a limiting baffle 108, and the other end of the bracket 102 is provided with a limiting locking assembly 109 spanning the storage bottle space 103. First, in terms of ease of operation, the system simplifies the complex operations of traditional bolt fixing, such as multiple alignments and tightening, to a single "push-in" action by using the low-friction support provided by the horizontal roller group and the guidance provided by the vertical roller group. This reduces the physical exertion and technical threshold of the operators, making the replacement process smooth and efficient. The replacement time is reduced from tens of minutes in the traditional method to several minutes, truly achieving the goal of "quick replacement" and effectively solving the pain point of the inconvenience of quick replenishment after the hydrogen in the 114 hydrogen storage cylinder is depleted. Secondly, in terms of safety, the system forms a robust "push-and-lock" constraint mechanism through the rigid limiting baffle 108 at the end and the limiting locking assembly 109 at the head. This mechanism not only prevents the hydrogen storage cylinder 114 from shifting or loosening during vehicle travel, ensuring stability during transportation and avoiding the risk of loosening of connecting pipes or structural collisions caused by cylinder displacement, but also has a highly reliable mechanical locking method that is not easily damaged by vibration. Furthermore, in terms of versatility and maintainability, the modular roller array design and equidistantly distributed mounting shafts allow it to adapt to standardized hydrogen storage cylinders 114 of different diameters and lengths, giving the system excellent scalability. At the same time, the rolling contact rather than rigid fixing method reduces scratches and wear on the outer wall of the hydrogen storage cylinder 114 during loading and unloading, effectively protecting the integrity of the cylinder, extending the service life of the hydrogen storage cylinder 114, and reducing maintenance costs. This invention uses a mounting bracket 101 fixed on a base plate 100 and a support 102 to form a storage space 103 for the hydrogen storage cylinder 114. A vertical mounting shaft 104 and a vertical roller 105 provide guidance and rolling, while a horizontal mounting shaft 106 and a horizontal roller 107 provide support and rolling, allowing the hydrogen storage cylinder 114 to move smoothly during installation. A limiting baffle 108 limits the end of the hydrogen storage cylinder 114, and a limiting locking assembly 109 conveniently locks the head of the hydrogen storage cylinder 114, thus enabling rapid replacement of the hydrogen storage cylinder 114. This solution effectively solves the problem of inconvenient loading and unloading of the hydrogen storage cylinder 114 in related technologies. By reducing friction through rolling components, it simplifies the operation process, improves replacement efficiency, and ensures the stable installation of the hydrogen storage cylinder 114, facilitating mid-journey refueling and maintenance, thereby enhancing the practicality and convenience of hydrogen energy vehicles.

[0019] In this embodiment of the utility model, the transverse mounting shaft 106 includes a top transverse shaft 110 mounted on the upper end of the bracket 102 and a bottom transverse shaft 111 mounted on the bottom of the bracket 102. The transverse roller component 107 includes a top roller component 112 mounted on the top transverse shaft 110 and a bottom roller component 113 mounted on the bottom transverse shaft 111. The top roller component 112 and the bottom roller component 113 are respectively in rotatable contact with the top and bottom of the outer wall of the hydrogen storage cylinder 114. like Figure 3 and 6 As shown, the transverse mounting shaft 106 is specifically configured to include a top transverse shaft 110 located at the upper end of the bracket 102 and a bottom transverse shaft 111 located at the bottom of the bracket 102. The transverse roller component 107 is also correspondingly divided into a top roller component 112 and a bottom roller component 113. With the top and bottom rollers 113 maintaining simultaneous rotational contact with the top and bottom of the outer wall of the hydrogen storage cylinder 114, the bottom roller 113 mainly bears the weight of the cylinder and provides smooth support during the installation of the hydrogen storage cylinder 114. The top roller 112 applies constraint from above and together with the bottom roller 113 forms a stable clamping guide track, effectively preventing the hydrogen storage cylinder 114 from tilting, jamming, or rigidly colliding with the bracket 102 during the push-in process. This significantly improves the stability and guiding accuracy of the hydrogen storage cylinder 114 during the loading and unloading process. The rolling contact at both the top and bottom points reduces frictional resistance, ensuring smooth and effortless operation, while avoiding scratches on the surface of the hydrogen storage cylinder 114 caused by sliding friction.

[0020] In this embodiment of the utility model, adjacent storage bottle spaces 103 share a set of vertical mounting shafts 104 and vertical roller components 105; like Figure 4 As shown, the same set of vertical rollers 105 located at the junction of the two storage cylinder spaces 103 simultaneously serve as lateral guide mechanisms for the hydrogen storage cylinders 114 on both sides. When any hydrogen storage cylinder 114 is inserted, the rollers effectively guide it to smoothly enter its respective space by rotating. This reduces the number of mounting shafts and rollers used, thereby reducing the overall material cost and structural complexity of the system. At the same time, it makes the structure more compact, which helps to arrange more storage cylinder spaces 103 in a limited space, improving the space utilization and modularity of the entire system.

[0021] In this embodiment of the utility model, the limiting locking assembly 109 includes a locking plate 116 rotatably mounted on the first bracket 102, and a fastening member 117 is fixedly provided on the bracket 102 adjacent to the first bracket 102. The fastening member 117 is engaged with the end of the locking plate 116, and the lower edge of the locking plate 116 is provided with an arc-shaped locking groove 118 that matches the contour of the hydrogen storage bottle 114. like Figure 3 As shown, when the hydrogen storage cylinder 114 is pushed into the storage space 103 along the guide roller and abuts against the end limiting baffle 108, the operator can rotate the locking plate 116 so that its arc-shaped locking groove 118 precisely engages with the outer wall of the head of the hydrogen storage cylinder 114. Then, the locking plate 116 is engaged and locked with the buckle 117 on the adjacent bracket 102, thereby using mechanical constraints to firmly press the hydrogen storage cylinder 114 from above the head. The arc-shaped locking groove 118 with a matching profile achieves a large area and high degree of contact with the hydrogen storage cylinder 114, which significantly improves the reliability and stability of locking and effectively prevents the hydrogen storage cylinder 114 from loosening due to vibration during vehicle operation. At the same time, its integrated locking action of "rotation-engagement-clamping" is extremely simple and quick, and while ensuring a firm lock, it further optimizes the replacement efficiency of the hydrogen storage cylinder 114.

[0022] In this embodiment of the present invention, the width of the end of the latch plate 116 is greater than the width of the tail. like Figure 3 As shown, by designing the end width of the locking plate 116 to be greater than the tail width, this structure makes the head of the locking plate 116 have a larger mass and the center of gravity shifted forward. Thus, under natural conditions, it can generate a downward torque to keep it locked by its own weight, effectively enhancing its static stability and preventing accidental unlocking due to vibrations during vehicle operation. At the same time, the tail of the locking plate 116 is narrowed, leaving ample space for the opening and rotation trajectory of the locking plate 116. On the one hand, it significantly improves the reliability and safety of the locking assembly in the locked state through a physical self-locking mechanism, avoiding the risk of accidental slippage of the hydrogen storage tank 114. On the other hand, the optimized design of the tail ensures smooth operation when the operator opens the locking plate 116.

[0023] In this embodiment of the utility model, a baffle 119 is fixed on the outermost bracket 102, and a viewing window 120 is opened on the baffle 119. The vertical roller 105 is disposed in the viewing window 120. like Figure 2 As shown, the baffle 119 acts as a physical barrier, effectively preventing external direct contact and intrusion into the roller system. At the same time, the viewing window 120 allows the vertical roller 105 to be partially exposed to perform its guiding function normally. It also facilitates direct observation of the wear and working status of the roller through the viewing window 120, allowing for daily inspections without disassembling the components.

[0024] In this embodiment of the utility model, a guide plate 121 inclined upward is provided below the limiting lock assembly 109, and the guide plate 121 extends toward the storage space 103; like Figure 4 and 6 As shown, an upwardly inclined guide plate 121 is provided below the limiting locking assembly 109, and the guide plate 121 extends toward the interior of the storage bottle space 103. When the operator inserts the hydrogen storage bottle 114, the head of the bottle will first contact the surface of this inclined guide plate 121, and be automatically and smoothly lifted and guided to the correct installation height and position by the guiding action of the inclined surface. This effectively avoids the collision, jamming or wear of the head of the hydrogen storage bottle 114 with the mounting frame 101 caused by manual misalignment, thus protecting the equipment components and reducing the difficulty of operation.

[0025] In this embodiment of the utility model, a roller mounting groove 122 is provided on the guide plate 121, and the bottom roller component 113 is installed in the roller mounting groove 122; like Figure 4 and 6As shown, by opening a roller mounting groove 122 on the inclined guide plate 121 and installing the bottom roller component 113 in the groove, the bottom support rolling function and the head guide function are integrated into one. This allows the bottom of the hydrogen storage bottle 114 to immediately contact the bottom roller component 113 protruding from the groove while the head is lifted and guided along the inclined surface of the guide plate 121. This achieves a seamless transition to a low-friction rolling conveying state, optimizes the smoothness of the continuous action of the hydrogen storage bottle 114 from initial contact to complete loading, and eliminates functional gaps and height differences between components. This not only simplifies the overall structure of the mounting frame 101 through structural integration, but more importantly, ensures that the hydrogen storage bottle 114 always receives stable and smooth support and guidance throughout the loading path, effectively preventing possible bumps, jams, or surface scratches on the bottle.

[0026] In this embodiment of the present invention, a stop plate 124 is provided on the substrate 100. The stop plate 124 is located at the front end of the guide plate 121. A relief groove 125 for supporting the tail end of the hydrogen storage bottle 114 is preset between the stop plate 124 and the guide plate 121. like Figure 4 As shown, when the hydrogen storage cylinder 114 needs to be unloaded, after releasing the head lock, the hydrogen storage cylinder 114 is pulled outward. When its tail end moves to the front of the system, it will fall into and abut against the relief groove 125. At this time, the stop plate 124 acts as a rigid physical block, which can effectively intercept the continued displacement of the tail end of the hydrogen storage cylinder 114. The reliable mechanical stop structure completely avoids the "tail swing" phenomenon of the hydrogen storage cylinder 114 due to inertia or improper operation during the removal process, and prevents the heavy cylinder from causing impact injury to the operator. At the same time, the design of the relief groove 125 ensures that the hydrogen storage cylinder 114 can be stably supported in the position to be loaded or unloaded, making the whole replacement process more controllable and safe. It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
