[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Reference below Figure 1 - Figure 6 A single-pole protection structure 10 of a vehicle-mounted hydrogen system 100 according to an embodiment of the present invention is described.

[0041] It is worth noting that the single-pole protection structure 10 proposed in this application is used to protect the hydrogen storage bottle, ensure its stable connection, and prevent it from being damaged by external impact during transportation and use, thereby achieving safe use of hydrogen energy. This single-pole protection structure 10 can also be applied to transportation scenarios involving other gas cylinders and gas tanks. In these scenarios, the single-pole protection structure 10 can ensure the safe storage and use of gas, thereby improving the safety of use and transportation.

[0042] like Figure 1 As shown, a single-pole protection structure 10 of a vehicle-mounted hydrogen system 100 according to some embodiments of the first aspect of the utility model is shown. The single-pole protection structure 10 includes a strap 11, a support rod 12 and a protection skin 15.

[0043] The binding belt 11 is used to cover and fix the gas cylinder 20. The binding belt 11 is used to provide a stable fixing effect to prevent the gas cylinder 20 from falling off from the single-pole protective structure 10.

[0044] like Figure 2 As shown, the support rod 12 is connected to the binding band 11, and the support rod 12 is arranged along the axial extension of the binding band 11, and a skin connector 13 is provided on the support rod 12. The support rod 12 can enhance the overall stability and rigidity of the single-pole protective structure 10. They not only provide a connection position for the protective skin 15, but also provide axial support for the gas cylinder 20 through its axially extending structure to prevent the gas cylinder 20 from being displaced under external impact or vibration. At the same time, the limitation of the support rod by the binding band 11 can also reduce the maximum displacement of the weak area at the farthest end of the support rod 12 in the axial direction of the binding band 11.

[0045] Therefore, the single-pole protection structure 10 of the present application has a simple structure, is easy to install, and has good consistency after installation.

[0046] Optionally, the support rod 12 is made of a high-strength material rod, including but not limited to: a carbon steel rod, a stainless steel rod, an aluminum alloy rod, a titanium alloy rod, a carbon fiber rod, a glass fiber composite material rod, and the like.

[0047] The protective skin 15 is connected to the skin connector 13 , and includes a skin side panel 151 extending along the axial direction of the binding belt 11 . The upper end of the skin side panel 151 is connected to the binding belt 11 and the rest is suspended.

[0048] This means that the upper end of the skin side panel 151 is connected to the strap 11, and the rest of the panel is suspended to form a space, so that the single-pole protection structure 10 can adapt to gas cylinders 20 of different sizes. At the same time, reducing the connection points between the upper end of the skin side panel 151 and the strap 11 can shorten the time for installing or removing the skin side panel 151, thereby improving the connection efficiency of the single-pole protection structure 10.

[0049] At the same time, the protective skin 15, as the outer layer of the single-pole protective structure 10, is connected to the skin connector 13 of the support rod 12, forming a certain wrapping and protection for the gas cylinder 20, ensuring that the gas cylinder 20 can be partially buffered when subjected to external force.

[0050] In some optional embodiments, the protective film layer is a polymer material layer. Such polymer material layers include but are not limited to: polyurethane layers, polytetrafluoroethylene layers or polycarbonate layers. These polymer material layers have excellent weather resistance, chemical stability and mechanical properties, and can provide better protection for the protective mask 1.

[0051] The protective film layer can be applied to the surface of the aluminum alloy plate by spraying, rolling or hot pressing to ensure that it is closely bonded to the surface of the aluminum alloy plate.

[0052] According to the single-pole protection structure 10 of the vehicle-mounted hydrogen system 100 of the embodiment of the present application, the support rod 12, the strap 11 and the protection skin 13 are connected to form a simple single-pole protection structure 10, which can greatly reduce the overall weight of the traditional frame, help to achieve lightweight vehicles, and also save the space required by the traditional frame.

[0053] According to some embodiments of the present invention, the single-pole protection structure 10 of the vehicle-mounted hydrogen system 100 is as follows: Figure 2 As shown, the support rod 12 includes: a main rod body 121, and a strap connector 14 connected to the main rod body 121. The skin connector 13 is arranged on the main rod body 121 and at least two are spaced apart along the length direction of the main rod body 121. The strap connector 14 is connected to the strap 11.

[0054] The main rod body 121 may include a straight rod or a curved rod to adapt to gas cylinders 20 of different shapes and sizes, thereby ensuring the connection effect between the support rod 12 and the gas cylinder 20 .

[0055] The function of the strap connector 14 is to achieve the connection effect between the strap 11 and the support rod 12 .

[0056] like Figure 2 As shown, according to some embodiments of the present invention, the single-pole protection structure 10 of the on-board hydrogen system 100 has cantilever ends 120 at both ends of the support rod 12, and at least three skin connectors 13 are spaced apart along the length direction of the support rod 12. By providing at least three skin connectors 13, uniform support force can be provided to the protective skin 15.

[0057] Generally speaking, the cantilever ends 120 at both ends of the support rod 12 correspond to the end positions of the gas cylinder 20 on both sides, and the skin connectors 13 are arranged at both ends of the support rod 12 to realize the protection of the ends of the gas cylinder 20 by the protective skin 15. The protective skin 15 forms a structure similar to a protective cover, and the gas cylinder 20 is completely arranged therein, thereby preventing the gas cylinder 20 from being damaged by external factors.

[0058] At the same time, since the cantilever end 120 has a smaller displacement characteristic in the radial direction, this design significantly enhances the stability of the support rod 12 and improves its supporting force on the gas cylinder 20.

[0059] Optionally, the ends of the gas cylinder 20 are provided with air pipes and other components, and the skin connectors 13 are provided at both ends of the support rod 12, which can also improve the protection of the protective skin 15 to the air pipes and other components at the ends of the gas cylinder 20, thereby enhancing the reliability and durability of the entire vehicle-mounted hydrogen system 100.

[0060] like Figure 3 As shown, the width of the two outermost skin connectors 13 is greater than the width of the skin connector 13 between them. The wider skin connector 13 can provide a larger connection area, and can more effectively apply tension to the protective skin 15. Even if the skin is slightly deformed under temperature changes or vibration conditions, it can maintain a stable connection with the support rod 12. At the same time, it avoids the phenomenon of excessive concentration of tension on both ends of the protective skin 15, thereby extending the service life of the protective skin 15.

[0061] When the skin is made of a softer material, the wider skin connector 13 can provide a larger connection area and a stronger gripping force, thereby significantly improving the connection effect of the skin at both ends of the support rod 12.

[0062] For example, there are eight skin connectors 13 spaced apart along the length direction of the support rod 12. Two of the skin connectors 13 are located at the two ends of the support rod 12, and the remaining six skin connectors 13 are located in the middle section of the support rod 12. Among the six skin connectors 13 in the middle section, the length dimensions of the innermost four skin connectors 13 are greater than the length dimensions of the two skin connectors 13 located at the two ends of the middle section.

[0063] This is because when the protective skin 15 is made of a relatively soft material, the protective skin 15 may sag due to the influence of gravity and other factors. The longer skin connectors 13 are used to increase the connection area of ​​the protective skin 15 in the middle section. These longer connectors can more effectively support and fix the protective skin 15, prevent it from sagging, and ensure that the protective skin 15 can provide complete protection for the gas cylinder 20.

[0064] At the same time, by preventing the protective skin 15 from sagging, unnecessary interference or contact between the protective skin 15 and other components can also be avoided, thereby protecting the safe and stable operation of the entire on-board hydrogen system 100.

[0065] In some optional embodiments, such as Figure 2 As shown, the support rod 12 is connected to the lower end of one side of the strap 11. At the same time, the support rod 12 is connected to the part of the strap connector 14 away from the gas cylinder 20. Prevent the support rod 12 from interfering with the gas cylinder 20.

[0066] like Figure 1 As shown, the protective skin 15 includes a skin bottom plate 152 , the lower edge of the skin side plate 151 is connected to the outer side edge of the skin bottom plate 152 , and the bottom of each skin connector 13 is connected to the skin bottom plate 152 .

[0067] The skin bottom plate 152 and the skin side plate 151 form an "L"-shaped structure. This structure not only provides side protection for the gas cylinder 20, but also forms a semi-enclosed protective space through the connection between the skin side plate 151 and the skin bottom plate 152, wrapping the gas cylinder 20 inside.

[0068] like Figure 4 As shown, the skin connector 13 further includes: a bottom connecting plate 131 and a side connecting plate 132. The bottom connecting plate 131 is horizontally arranged and connected to the skin bottom plate 152. The side connecting plate 132 is vertically arranged and connected to the bottom connecting plate 131 at the lower edge, and the upper end of the side connecting plate 132 is connected to the main rod body 121.

[0069] The bottom connecting plate 131 is provided to ensure a stable connection between the skin bottom plate 152 and the support rod 12 , while also providing a support and connection basis for the side connecting plates 132 .

[0070] Through the connection between the side connecting plate 132 and the main rod body 121 , the skin connector 13 can firmly fix the protective skin 15 on the support rod 12 to form a single-rod protective structure 10 .

[0071] In some optional embodiments, such as Figure 4 As shown, the main rod body 121 is a round rod, and the skin connector 13 includes a first arc plate 133, which is sleeved on the outside of the main rod body 121 and welded, and the lower end of the first arc plate 133 is connected to the upper end of the side connecting plate 132. The first arc plate 133, the side connecting plate 132 and the bottom connecting plate 131 are an integrated bent and formed part.

[0072] The inner side of the first arc plate 133 is matched with the outer peripheral wall of the round rod, which not only improves the tightness of the connection between the skin connector 13 and the main rod body 121, but also effectively prevents the skin connector 13 from loosening under vibration or impact.

[0073] It is worth noting that the first arc plate 133, the side connecting plate 132 and the bottom connecting plate 131 in the skin connecting member 13 are formed by an integral bending molding. This is conducive to simplifying the manufacturing process, and also improves the overall strength and stability of the skin connecting member 13, providing a reliable guarantee for the safe operation of the vehicle-mounted hydrogen system 100.

[0074] In some optional embodiments, the skin connector 13 further includes: a connecting reinforcement rib 134 provided on the bottom connecting plate 131 , the connecting reinforcement rib 134 is vertically arranged to the main rod body 121 , and is welded to at least one of the bottom connecting plate 131 and the side connecting plate 132 .

[0075] The connection reinforcement ribs 134 play a role in supporting and enhancing the strength of the skin connector 13, and can effectively prevent the skin connector 13 from being deformed due to external forces, thereby ensuring the stability and reliability of the connection. In addition, the connection reinforcement ribs 134 also play a certain role in limiting the support rod 12. This limiting effect makes the support rod 12 more stable during use, effectively avoiding possible shaking and deformation, thereby further improving the stability and safety of the entire single-pole protective structure 10.

[0076] For example, the connecting reinforcement rib 134 is welded to the main rod body 121. Since the connecting seam between the main rod body 121 and the connecting reinforcement rib 134 is straight, such welding is conducive to the welding operation. Alternatively, the connecting reinforcement rib 134 is welded to the side connecting plate 132. When in use, the connecting reinforcement rib 134 has a good supporting effect on the side connecting plate 132, and improves the supporting strength of the connecting reinforcement rib 134 to the side connecting plate 132. Alternatively, in order to achieve the best supporting strength, the connecting reinforcement rib 134 can also be welded to both the main rod body 121 and the side connecting plate 132.

[0077] In some Figure 4 In the illustrated embodiment, the skin connector 13 further includes a connection hole 135 for connecting the protective skin 15 . The connection hole 135 is formed on the bottom connecting plate 131 .

[0078] The connecting holes 135 are used to fix the skin connecting member 13 to the protective skin 15 through appropriate fasteners, such as bolts, nuts, etc., so as to achieve a firm connection between the skin connecting member 13 and the protective skin 15 .

[0079] In some other embodiments not shown in the figures, the skin connector 13 includes a buckle structure for connecting the support rod 12. In this way, it can be fixed to the support rod 12 through the buckle structure. The buckle connector has one or more openings, and the support rod 12 can pass through these openings and be fixed by the buckle structure, which can provide a strong fixing force.

[0080] In some optional embodiments, the main rod body 121 is a round rod, such as Figure 5As shown, the strap connector 14 includes: a second arc plate 141 and a connecting end plate 142. The second arc plate 141 is covered and welded to the end of the main rod body 121. The second arc plate 141 connects the support rod 12 and the strap 11. The inner arc portion of the second arc plate 141 fits the outer circumference of the gas cylinder 20 to ensure the stability of the gas cylinder 20. The main rod body 121 passes through the second arc plate 141, thereby achieving the connection effect between the support rod 12 and the strap 11.

[0081] Combination Figure 6 The strap connector 14 is a part of the strap 11 .

[0082] The connecting end plate 142 is vertically arranged with the main rod body 121 and the second arc plate 141 and is welded to the end surface of the strap 11, and the connecting end plate 142 can be detached or welded to the end surface of the strap 11. The connecting end plate 142 provides support force for the second arc plate 141. When the connecting end plate 142 is supported on the second arc plate 141, the connecting end plate 142 provides uniform support force for it. This support force can effectively prevent the second arc plate 141 from being skewed or deformed when subjected to external force. Since the connection between the second arc plate 141 and the main rod body 121 and the strap 11 is achieved by welding, once the connecting end plate 142 remains stable, it can provide support force for the structure of the strap connector 14 and avoid the risk of falling off between the support rod 12 and the strap 11.

[0083] In some Figure 5 In the illustrated embodiment, the strap connector 14 includes at least two second arc plates 141 and a connecting end plate 142. The plurality of second arc plates 141 are arranged at intervals along the axial direction of the gas storage cylinder 20, and the connecting end plate 142 is connected to the same side of the plurality of second arc plates 141. The main rod body 121 passes through the plurality of second arc plates 141 in sequence.

[0084] By providing a plurality of second arc plates 141, the stability and strength of the strap connector 14 can be improved. The use of a plurality of second arc plates 141 not only enhances the strength of the strap connector 14, but also avoids the bending phenomenon that may occur when a single second arc plate 141 is subjected to external force. Through the synergistic effect of the plurality of arc plates, the strap connector 14 can better resist external impact and vibration, thereby ensuring the stability and safety of the gas cylinder 20.

[0085] The main rod 121 passes through a plurality of second arc plates 141 in sequence to play a role of connection and fixing. The main rod 121 can evenly distribute the local external force to the entire strap connector 14 through cooperation with the plurality of second arc plates 141, thereby improving the force bearing capacity of the strap 11.

[0086] In some optional embodiments, there is at least one binding strap 11 , and when there are at least two binding straps 11 , the two binding straps 11 are spaced apart from each other in the axial direction.

[0087] For example, when there is only one binding strap 11 , the support rod 12 passes through the binding strap 11 to be connected to the gas cylinder 20 .

[0088] As another example, when there are more than two straps 11, these straps 11 are spaced apart in the axial direction. By providing multiple straps 11, it is ensured that the gas cylinder 20 can be fixed evenly and stably. The support rod 12 passes through these straps 11 in the axial direction, and in this way, the support rod 12 also provides axial support and stability for the entire single-rod protection structure 10.

[0089] The support rod 12 includes at least two sections separated by the strap 11 (for the convenience of understanding the scheme in conjunction with the accompanying drawings, Figure 3 Each section of the support rod is indicated by a character X in the figure, and at least two skin connectors 13 are spaced apart on each section to connect the protective skin 15.

[0090] This segmented support rod 12 not only makes installation and disassembly easier, but also effectively controls manufacturing costs, because each segment can be manufactured separately and combined according to needs, avoiding unnecessary material waste. If a certain segment of the support rod 12 needs to be replaced, only the segment needs to be replaced separately, without replacing the entire support rod 12. This modular maintenance method can save maintenance time and labor costs.

[0091] According to the vehicle-mounted hydrogen system 100 of the second aspect of the present utility model, Figure 6 As shown, it includes: a single-pole protection structure 10, a gas storage cylinder 20 and a control valve assembly 30.

[0092] The single-pole protection structure 10 adopts the single-pole protection structure 10 of the vehicle-mounted hydrogen system 100 of the first embodiment of the present application. The gas cylinder 20 is fixed in the strap 11 and arranged along the axial direction of the strap 11. The control valve assembly 30 is connected to the gas cylinder 20.

[0093] The straps 11 and the support rods 12 serve as a connecting bridge to establish a stable connection between the protective skin 15 and the gas cylinder 20, effectively dispersing the external impact force and protecting the gas cylinder 20 from direct damage. The single-rod protection structure 10 not only improves the durability and safety of the gas cylinder 20, but also ensures the stable operation of the on-board hydrogen system 100 under complex environmental conditions. At the same time, the existence of the protective skin 15 also plays multiple roles such as heat insulation and dust prevention, further enhancing the comprehensive protection effect of the gas cylinder 20.

[0094] As a part of the vehicle-mounted hydrogen system 100, the control valve assembly 30 is responsible for controlling the flow and release of hydrogen. It is connected to a part of the gas storage bottle 20, and the control valve assembly 30 is located in the single-rod protection structure 10, further improving the operating stability of the vehicle-mounted hydrogen system 100.

[0095] In some optional embodiments, the control valve assembly 30 includes a pressure reducing valve 31, and a skin connector 13 is provided at the end of the support rod 12, and the pressure reducing valve 31 is installed on the skin connector 13 at the end. In this arrangement, the pressure reducing valve 31 is located entirely within the protective skin 15, thereby increasing the protection range of the single-rod protective structure 10 for the control valve assembly 30, thereby improving the safety of the on-board hydrogen system 100.

[0096] In some embodiments, a mounting through hole is provided on the skin connector 13 at the end, which is used to achieve the connection between the skin connector 13 and the pressure reducing valve 31 .
