[0002] The hydrogen storage system protection devices used in current fuel cell vehicle light trucks and medium trucks are relatively complex in structure, and their design usually involves the combination and splicing of multiple components such as the bottom plate, front guard plate, rear guard plate, and side guard plate. This multi-component assembly method not only leads to a complex structure and many connection points, which is not conducive to disassembly and assembly. It also increases the weight of the hydrogen storage system protection device, making the weight of the entire on-board hydrogen system heavier, which is not conducive to the lightweight development of the vehicle. More importantly, the hydrogen storage system protection device generally adopts a right-angle structure in the appearance design of the connection. This right-angle structure causes the hydrogen storage system protection device to occupy a large space in the vehicle, which is not conducive to the spatial layout of the vehicle.

[0003] Therefore, there is room for improvement in the protective structure of the on-board hydrogen system. Utility Model Content

[0032] Reference below Figure 1-Figure 3 The protective cover 1 of the vehicle-mounted hydrogen system 100 according to the first embodiment of the utility model is described.

[0033] like Figure 1 As shown, the protective panel 1 of the vehicle-mounted hydrogen system 100 according to the embodiment of the utility model comprises: a skin bottom plate 11 and a skin side plate 12. The upper part of the skin bottom plate 11 constitutes a placement space for placing the gas cylinder 2, and one side edge of the skin bottom plate 11 is the outer side edge. The lower edge of the skin side plate 12 is connected to the outer side edge of the skin bottom plate 11, and the skin side plate 12 and the skin bottom plate 11 are an integral bent and formed part.

[0034] First, by providing the interconnected skin bottom plate 11 and skin side plates 12, the protective mask 1 constructs a semi-enclosed structure, and the gas cylinder 2 is safely placed on the inner side of the structure, which can improve the stability and reliability of the gas cylinder 2, ensure that the gas cylinder 2 can remain stable during the driving of the vehicle, and reduce potential risks caused by bumps or collisions. This design eliminates the connection points and gaps between multiple components in the traditional design, thereby reducing the additional space occupied by connectors and corners. Avoiding the space waste caused by the right-angle structure allows the protective mask 1 of the on-board hydrogen system 100 to more effectively utilize the surrounding space while protecting the gas cylinder 2, thereby improving the overall space utilization.

[0035] In addition, the semi-enclosed structure also facilitates the installation and maintenance of the vehicle-mounted hydrogen system 100. Since the vehicle-mounted hydrogen system 100 is semi-enclosed inside the protective mask 1, it can be installed and fixed more easily. At the same time, when the gas cylinder 2 needs to be checked, the protective skin side panel 12 can be untied to expose the gas cylinder 20 for inspection without removing the entire protective mask 1.

[0036] Since the skin side panels 12 and the skin bottom panel 11 are integrally formed bent parts, there is no gap or interface at the connection between them, which can avoid the potential risk of loosening or breaking. The seamless connection allows the protective panel 1 to maintain a more stable shape when subjected to external impact, effectively protecting the gas cylinder 2, thereby improving the stability of the vehicle-mounted hydrogen system 100.

[0037] In some embodiments, the cross-section of the protective mask 1 is oriented in the same direction as the driving direction. When the vehicle is driving, the air resistance generated by the protective mask 1 during driving can be reduced to the maximum extent.

[0038] In addition, the cross section of the protective panel 1 facing the driving direction also helps to improve the stability of the vehicle, so that the vehicle can better cope with external interference such as wind resistance when driving at high speed and maintain a stable driving posture.

[0039] According to some embodiments of the present invention, the protective mask 1 is as follows: Figure 1-Figure 2 As shown, the upper end of the skin side panel 12 forms a curved section 121 that gradually extends upward toward the placement space. The curved section 121 can not only enhance the bending resistance of the skin side panel 12. When subjected to a large lateral pressure, the skin side panel 12 can also maintain its original shape and position and is not easily deformed or damaged.

[0040] Since the curved section 121 extends toward the placement space, the relative area between the protective mask 1 and the gas cylinder 2 is increased, which means that the protective mask 1 can more effectively wrap and fix the gas cylinder 2, thereby improving the stability of the gas cylinder 2 during vehicle driving. In addition, the increased relative area also helps to improve the impact resistance of the protective mask 1. Since the contact area between the protective mask 1 and the gas cylinder 2 is larger, when the vehicle is subjected to external impact, the protective mask 1 can better withstand and disperse the impact force, thereby reducing the risk of local damage and deformation of the gas cylinder 2.

[0041] like Figure 2 As shown, the protective panel 1 according to some embodiments of the present invention further includes a skin end plate 13. The skin end plate 13 is located at at least one end of the skin bottom plate 11 in the length direction, and the lower edge of the skin end plate 13 is connected to the skin bottom plate 11 and the side edge is connected to the skin side plate 12.

[0042] The skin end plate 13 connects the skin bottom plate 11 and the skin side plate 12, which can not only disperse the external force to the entire structure of the protective panel 1, rather than just concentrate it on a certain point, thereby effectively reducing the force burden of a single part. At the same time, the provision of the skin end plate 13 can also enhance the overall rigidity of the protective panel 1. When impacted by external force, the skin end plate 13 can prevent excessive relative displacement or deformation between the skin bottom plate 11 and the skin side plate 12, and maintain the shape and structural stability of the entire protective panel 1.

[0043] The skin end plate 13 , the skin side plate 12 and the skin bottom plate 11 are an integrated bent and formed part, and the skin end plate 13 is welded to one of the skin side plate 12 and the skin bottom plate 11 .

[0044] Specifically, one side of the skin end plate 13 is a bent edge connected to the skin side plate 12, and the other side of the skin end plate 13 is welded to the skin bottom plate 11. In this way, the skin end plate 13, the skin side plate 12 and the skin bottom plate 11 can be formed by bending an integral plate and then welding them together, and the two are connected into one to form a semi-frame structure with a stable shape.

[0045] This arrangement ensures that the connection between the skin end plate 13 and the skin bottom plate 11 or the skin side plate 12 has a high structural integrity and stability. At the same time, since the skin end plate 13, the skin side plate 12 and the skin bottom plate 11 are integrally formed, there is no need for complicated debugging work, which reduces production costs and manufacturing cycle, and the protective panel 1 also becomes simpler and more efficient during the manufacturing process.

[0046] Specifically, the bottom side of the skin end plate 13 is integrally formed with the skin bottom plate 11, and the vertical side of the skin end plate 13 is welded to the skin side plate 12. Alternatively, the vertical side of the skin end plate 13 is integrally formed with the skin side plate 12, and the bottom side of the skin end plate 13 is welded to the skin bottom plate 11.

[0047] like Figure 3 As shown, according to some embodiments of the present invention, the protective mask 1 is provided with at least one adjustment opening 14 for avoiding, and the adjustment opening 14 is provided through the skin side panel 12. By providing the adjustment opening 14, the position between the skin side panel 12 and the gas storage cylinder 2 can be exposed, so as to facilitate the operation and maintenance of the inner area of ​​the skin side panel 12 by the operator, avoid disassembling unnecessary parts, and improve the efficiency of disassembly and assembly.

[0048] Optionally, a portion of the adjustment port 14 is disposed on the skin side panel 12 , and another portion is disposed on the skin bottom panel 11 , so that the operating tool can work more flexibly on the gas cylinder 2 when adjustment is required.

[0049] In some optional embodiments, a cover plate is provided at the adjustment opening 14. The cover plate is rotatably or detachably formed on the skin side panel 12 to open and close the adjustment opening 14. When no operation is required, the adjustment opening 14 can be closed to protect the inner area of ​​the skin side panel 12 from interference and damage from the external environment. When operation is required, the operator can conveniently open the cover plate and operate the inner area of ​​the skin side panel 12 through the adjustment opening 14.

[0050] In some optional embodiments, the adjustment port 14 and the ventilation port are the same port.

[0051] According to some embodiments of the present invention, the protective mask 1 is as follows: Figure 3 As shown, the skin side panels 12 and / or the skin bottom panel 11 are provided with reinforcing ribs 15. The provision of the reinforcing ribs 15 helps to improve the overall structural strength and stability of the protective panel 1.

[0052] In some embodiments, the reinforcing ribs 15 are arranged on the skin side panels 12. Such an arrangement can effectively enhance the rigidity and force bearing capacity of the skin side panels 12, and can provide better support and stability, especially when facing lateral external forces.

[0053] In other embodiments, the reinforcing ribs 15 are arranged on the skin bottom plate 11. Such an arrangement can enhance the load-bearing capacity and impact resistance of the protective panel 1. When the vehicle is traveling on a bumpy road, such an arrangement can effectively disperse and reduce the direct force of the road impact on the protective panel 1, thereby reducing the risk of damage to the onboard hydrogen system 100 and the protective panel 1 itself.

[0054] In some other embodiments, Figure 3 As shown, the reinforcing ribs 15 are arranged on the skin side panels 12 and the skin bottom panel 11. Such arrangement not only enhances the strength of the side panels of the panel, but also enhances the supporting capacity of the bottom panel of the panel, so that the protective panel 1 can maintain its original shape and protective function under complex road conditions, providing continuous and reliable protection for the on-board hydrogen system 100.

[0055] In some optional embodiments, there is at least one reinforcing rib 15 , and the at least one reinforcing rib 15 extends from the skin side panel 12 to the skin bottom panel 11 .

[0056] In this way, the strength of the skin side panels 12 and the skin bottom panel 11 can be enhanced. When encountering external force impact, the reinforcing ribs 15 can disperse and reduce the impact force, thereby reducing the risk of cracking or damage to the skin side panels 12 and the skin bottom panel 11 themselves, and improving the service life of the protective panel 1. At the same time, the skin side panels 12 and the skin bottom panel 11 are firmly connected by the reinforcing ribs 15, thereby effectively avoiding deformation or displacement caused by bumps, vibrations or other external factors during vehicle driving. This stability ensures that the internal space of the protective panel 1 is maintained in a constant state, providing a reliable protection environment for the on-board hydrogen system 100.

[0057] In such Figure 3 In the illustrated embodiment, there are five reinforcing ribs 15, which are arranged at intervals along the length direction of the protective panel 1, and each reinforcing rib 15 extends from the skin side panel 12 to the skin bottom panel 11. In this way, an orderly support structure can be formed, and each reinforcing rib 15 plays a certain role, supporting the protective panel 1 like a skeleton, so that it can maintain its original shape and stability when subjected to external impact or pressure, ensuring that the reinforcing ribs 15 comprehensively and evenly enhance the strength of the protective panel 1, thereby better protecting the gas cylinder 2 inside.

[0058] According to the protective mask 1 of some embodiments of the present invention, the protective mask 1 is an aluminum alloy plate.

[0059] Since the aluminum alloy plate is light in weight, high in strength and good in corrosion resistance, it is suitable for various scenarios requiring protection and support. When the aluminum alloy plate is used in the protective mask 1, the aluminum alloy plate not only provides the necessary structural strength, but also ensures the overall lightweight, reduces the vehicle's energy consumption, and is conducive to improving the vehicle's endurance.

[0060] A protective film layer is provided on the surface of the protective mask 1. This protective film layer can reduce the erosion of the external environment on the protective mask 1, such as chemical corrosion, etc. In addition, the protective film layer can also increase the wear resistance and impact resistance of the protective mask 1, thereby extending its service life.

[0061] 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.

[0062] 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.

[0063] like Figure 1 As shown, the vehicle-mounted hydrogen system 100 according to the second aspect of the embodiment of the utility model includes: a protective mask 1 and a gas storage cylinder 2.

[0064] The protective mask 1 is the protective mask 1 of the vehicle-mounted hydrogen system 100 in the first embodiment of the present application. The gas cylinder 2 is located in the placement space.

[0065] The gas cylinder 2 is a component for storing hydrogen in the vehicle-mounted hydrogen system 100, and is located in the placement space surrounded by the protective mask 1. This layout ensures that the gas cylinder 2 is supported and protected by the protective mask 1, improves the stability and reliability of the gas cylinder 2 during vehicle operation, and can also reduce damage or leakage of the gas cylinder 2 caused by external impact, vibration and other factors. At the same time, the structure of the protective mask 1 can also ensure that the gas cylinder 2 can be easily inspected when necessary.

[0066] like Figure 4 As shown, the vehicle according to the third embodiment of the utility model comprises: a vehicle body longitudinal beam and a vehicle-mounted hydrogen system 100. The vehicle-mounted hydrogen system 100 is the vehicle-mounted hydrogen system 100 of the second embodiment of the present application, and the vehicle-mounted hydrogen system 100 is installed on the horizontal side of the vehicle body longitudinal beam.

[0067] This installation method can balance the distribution of vehicle load. Since the on-board hydrogen system 100 is installed on one side of the vehicle body longitudinal beam, there is enough space on the other side of the vehicle body longitudinal beam to install other important components, such as batteries. This layout helps to balance the load distribution of the vehicle, making the left and right weight distribution of the vehicle more even, thereby optimizing the vehicle's handling performance and driving stability. During driving, balanced load distribution can ensure that the vehicle can maintain a stable posture under various road conditions and improve the safety of the vehicle.

[0068] By providing the on-board hydrogen system 100 in the second aspect embodiment, the vehicle in the third aspect embodiment of the utility model has an on-board hydrogen system 100 with high safety and reliability.
