[0026] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, in which the same or similar components have the same or similar designations and functions throughout, and examples of the embodiments are described by referring to the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present disclosure, and are not to be understood as limiting the present disclosure.

[0027] A storage bottle mounting frame 10 of a vehicle-mounted hydrogen system according to an embodiment of the first aspect of the present disclosure is described below with reference to FIGS. 1-5.

[0028] It is worth noting that the storage bottle mounting frame 10 of the vehicle-mounted hydrogen system according to the present disclosure is used to protect the hydrogen storage bottle in a vehicle-mounted scenario, ensure stable connection, and reduce damage caused by external impact during transportation and use, thereby realizing safe use of hydrogen energy. The storage bottle mounting frame 10 of the vehicle-mounted hydrogen system can also be applied to other vehicle-mounted scenarios involving gas bottles and gas tanks, in which the storage bottle mounting frame can ensure the safe storage, transportation, and use of gas, thereby improving the reliability and safety of gas bottles and gas tanks.

[0029] As shown in FIG. 1, the storage bottle mounting frame 10 of the vehicle-mounted hydrogen system according to an embodiment of the first aspect of the present disclosure. The storage bottle mounting frame includes a binding belt 2, a supporting rod 3, and a protective skin 1.

[0030] The binding belt 2 is used to cover and fix the storage bottle, one side of the binding belt 2 is used to be fixed laterally on the vehicle body longitudinal beam, and the other side of the binding belt 2 is provided with an adjusting mechanism 23 for adjusting the size of the circular opening.

[0031] The binding belt 2 is the basic structure connecting the storage bottle and the vehicle, which ensures that the storage bottle can be stably connected to the vehicle, thereby guaranteeing the basic use and safe operation of the vehicle-mounted hydrogen system 100.

[0032] The main function of the adjusting mechanism 23 is to adjust the size of the circular opening.

[0033] Since the storage bottle expands or shrinks with the change of internal pressure during use. Therefore, by using the binding belt 2 of the present disclosure, the expansion amount of the storage bottle can be absorbed through the adjusting mechanism 23, and as the gas in the storage bottle is slowly consumed, the binding belt 2 automatically reduces the size of the circular opening through the adjusting mechanism 23 to tighten the storage bottle at all times.

[0034] As shown in FIG. 2, the binding belt 2 is at least two and arranged in an axial direction. Two or more binding belts 2 can improve the fixing effect of the storage bottle, and the circumferential direction of the binding belt 2 is the same as that of the storage bottle, so that the binding belt 2 can be evenly distributed around the storage bottle, thereby providing omnidirectional and balanced structural bearing and fixing.

[0035] The support rod 3 connects the binding belt 2. The support rod 3 provides stable connection for the binding belt 2, and also enhances the connection effect of the binding belt 2 with the storage bottle. Multiple binding belts 2 are connected through the support rod 3, which can form a more stable structure. Especially when the storage bottle mounting frame is applied in a high-vibration environment, such as a vehicle driving environment, the support rod 3 can reduce the loosening or deviation caused by the single stress of the binding belt 2.

[0036] As shown in FIG. 3, the protective skin 1 is provided with an adjusting opening 13 opposite to the adjusting mechanism 23. By setting the adjusting opening 13, the adjusting mechanism 23 is exposed to the operator, so that when the size of the circular opening needs to be adjusted, the operator can conveniently operate the adjusting mechanism 23, further improving the use convenience of the storage bottle mounting frame 10.

[0037] Optionally, the protective skin 1 is made of a wear-resistant and corrosion-resistant material. Such a material can resist damage to the storage bottle in some harsh environments. In addition, the protective skin 1 can also be customized according to specific needs, such as using a fireproof material to improve fireproof performance, or using an insulating material to prevent static electricity accumulation, etc.

[0038] At the same time, the protective skin 1 has certain elasticity and toughness, such as polyester fabric, nylon fabric, high-performance engineering plastic fabric, carbon fiber fabric or glass fiber fabric, etc. This is because the fabric can adaptively adjust with the shape and size changes of the storage bottle. Whether it is a circular, elliptical or other irregularly shaped storage bottle, the protective skin 1 can be attached to its surface to form a protective layer. This adaptive adjustment capability not only enhances the protection effect of the protective skin 1, but also enables it to adapt to storage bottles of various shapes, thereby helping to improve the adaptability of the storage bottle mounting frame.

[0039] The protective skin 1 includes: a skin side plate 12 blocking the side of the binding belt 2 away from the vehicle body longitudinal beam, and a skin bottom plate 11 connecting the lower edges of the skin side plate 12. Thus, the skin bottom plate 11 and the skin side plate 12 form a "L" shaped structure, forming a semi-enclosed protective space, and the storage bottle is arranged in the "L" shaped structure to improve the protection of the side and bottom of the storage bottle.

[0040] The skin bottom plate 11 connects the support rod 3 and the binding belt 2.

[0041] The double fixation of the support rod 3 and the binding belt 2 can enhance the adhesion and stability of the skin bottom plate 11. Especially when the protective skin 1 is made of soft material, the skin bottom plate 11 is prone to sagging due to the influence of gravity and external environmental factors. At this time, the support rod 3 and the binding belt 2 provide uniform support and stable binding for the skin bottom plate 11 through double fixation, reducing the sagging of the skin bottom plate 11 and ensuring its effective protection of the bottom of the storage bottle.

[0042] In addition, this double fixing method also helps to reduce unnecessary contact or interference between the skin bottom plate 11 and other vehicle components. By keeping the stable position of the skin bottom plate 11, the friction or collision with other components is reduced, thereby protecting the overall safety and stable operation of the vehicle-mounted hydrogen system 100. In this way, the reliability of the storage bottle mounting frame is improved, and the service life of the vehicle-mounted hydrogen system 100 is prolonged.

[0043] The skin side plate 12 is connected to the binding belt 2. In this way, the stable connection of the skin side plate 12 and the storage bottle can be realized, and the skin side plate 12 can be ensured to be stably positioned at the side of the storage bottle and form effective protection. In addition, when the skin side plate 12 is a flexible material piece, when the storage bottle needs to be viewed, the connection between the skin side plate 12 and the binding belt 2 can be disassembled, so that the skin side plate 12 can be opened downward. In this way, it is convenient to view the storage bottle, and the whole protective skin 1 is avoided to be disassembled, so that the operation efficiency and convenience are greatly improved.

[0044] The support rod 3 is arranged along the axial direction of the binding belt 2. The support rod 3 penetrates through a plurality of binding belts 2, and the arrangement ensures that the skin bottom plate 11 can cover and closely fit on the entire length of the storage bottle, and the structure improves the comprehensiveness of protection.

[0045] As shown in FIG. 1, the skin bottom plate 11 is suspendedly arranged except at the connection with the support rod 3 and the binding belt 2. This design ensures the stable connection of the skin bottom plate 11 and the storage bottle, and at the same time, guarantees the comprehensiveness and effectiveness of the protection, simplifies the installation steps, and improves the work efficiency. In addition, this design also helps to reduce the manufacturing cost.

[0046] The skin side plate 12 is suspendedly arranged except at the connection with the binding belt 2. In this way, the connection points between the skin side plate 12 and the binding belt 2 can be reduced, and the installation steps can be reduced. At the same time, the skin side plate 12 arranged in suspension reduces the direct contact area with the storage bottle, increases the space for air flow around the storage bottle, makes the heat and leaked hydrogen more easily dissipate to the environment, helps to dissipate heat of the storage bottle and the surrounding components, reduces the aggregation of leaked hydrogen, and further ensures the safety and reliability of the vehicle-mounted hydrogen system 100.

[0047] According to some embodiments of the present disclosure, the storage bottle mounting frame 10 of the vehicle-mounted hydrogen system is shown in FIG. 2. The binding belt 2 is a circular ring, and the support rod 3 is one and located at the lower end of the skin side plate 12.

[0048] The circular ring-shaped binding belt 2 can uniformly fix around the circumference of the storage bottle and provide stable and uniform support force.

[0049] The support rod 3 is one and is located at the lower end of the skin side plate 12. While achieving the connection effect of the support rod 3 to the storage bottle mounting frame, by arranging it inside the lower end arc of the skin side plate 12, it can be ensured that the support rod 3 does not occupy too much space around the storage bottle, thereby reducing the possibility of position conflict with the storage bottle.

[0050] The skin side plate 12 and the skin bottom plate 11 are connected in an arc shape. Compared with a right angle or an acute angle connection mode, the arc-shaped transition connection can better disperse and withstand external impact force, reduce stress concentration, thereby improving the impact resistance of the protective skin 1, enhancing the overall strength of the protective skin 1, and reducing the space occupancy.

[0051] Secondly, due to the arc-shaped transition, air can flow more smoothly through the arc-shaped transition connection of the protective skin 1, taking away the heat accumulated between the protective skin 1 and the storage bottle, which helps to maintain the appropriate working temperature of the vehicle-mounted hydrogen system 100 and prevent overheating.

[0052] The storage bottle mounting frame 10 of the vehicle-mounted hydrogen system according to some embodiments of the present disclosure, as shown in FIG. 3, the adjusting port 13 is located at the connection between the skin side plate 12 and the skin bottom plate 11. By lowering the position of the adjusting port 13, it is beneficial to reduce the height of the skin side plate 12, and thus reduce its side area. In this way, not only can the storage bottle mounting frame be more compact, but also the amount of material used can be effectively reduced, thereby reducing the overall cost of the storage bottle mounting frame. At the same time, it can also reduce the weight of the storage bottle mounting frame, thereby realizing the lightweight of the vehicle and improving the utilization rate of hydrogen energy.

[0053] The storage bottle mounting frame 10 of the vehicle-mounted hydrogen system according to some embodiments of the present disclosure, as shown in FIG. 4, the support rod 3 includes at least three sub-rod segments 30 spaced apart by the binding belt 2, and the end of the sub-rod segment 30 is fixedly connected to the binding belt 2 in the axial direction.

[0054] Such sub-rod segments 30 not only make installation and disassembly easier, but also effectively control manufacturing costs, because each segment can be manufactured separately and combined according to needs, avoiding unnecessary material waste. If a certain sub-rod segment 30 needs to be replaced, only the segment needs to be operated separately, without the need to replace the entire support rod 3. This modular maintenance method can save maintenance time and labor costs.

[0055] The end of the two outermost sub-rod segments 30 in the axial direction is fixedly connected to the binding belt 2, and the other end is a cantilever rod 31. The two outermost sub-rod segments 30 in the axial direction can improve the connection area of the protective skin 1. Since the above two sub-rod segments 30 correspond to the two ends of the storage bottle, they can set the protective skin 1 at the end of the storage bottle, thereby effectively protecting the end of the storage bottle and other components around the end.

[0056] In addition, the cantilever rod 31 also adds flexibility to the protective skin 1, allowing it to adapt to different shapes and sizes of the storage bottle. By adjusting the length and angle of the cantilever rod 31, the protective effect of the protective skin 1 on the storage bottle can be ensured.

[0057] According to some embodiments of the present disclosure, the storage bottle mounting frame 10 of the vehicle-mounted hydrogen system is an integrated bending molding of the skin side plate 12 and the skin bottom plate 11.

[0058] The integrated bending molding not only simplifies the manufacturing process, but also reduces potential failure points by reducing the area of the connection. Traditional connection structures usually include independent components that need to be connected together by bolts, welding or other means. However, such connection methods are prone to looseness under vibration or impact, thereby affecting the sealing and protection effect of the connection.

[0059] The integrated bending molding eliminates stress concentration at the connection, reducing the risk of failure due to loose connections. At the same time, the integrated structure is also beneficial to enhance the overall strength and stiffness of the storage bottle mounting frame, so that it can better resist external impact and vibration.

[0060] According to some embodiments of the present disclosure, the storage bottle mounting frame 10 of the vehicle-mounted hydrogen system includes at least two segments distributed circumferentially, and the adjusting mechanism 23 is located between the adjacent two segments. The relative position between the adjacent binding segments can be changed by the adjusting mechanism 23, so as to adjust the size of the circular opening of the binding belt 2.

[0061] As shown in FIG. 5, the adjusting mechanism 23 is an elastic adjusting mechanism.

[0062] Firstly, the elastic adjusting mechanism already has a certain pre-tightening force when the binding belt 2 is not fully tightened. This pre-tightening force can help the binding belt 2 better fit on the storage bottle wall, ensuring the preliminary fixing effect.

[0063] Secondly, the elastic adjusting mechanism can ensure that the binding belt 2 exerts a constant pressure on the storage bottle in the fastened state. This constant pressure helps to maintain the stability of the storage bottle, effectively reducing the safety risk of the binding belt loosening caused by the radial expansion of the storage bottle during the cyclic filling process, and making up for the loss of the binding belt torque.

[0064] At the same time, during the driving of the vehicle, the storage bottle may be subjected to vibration. The elastic adjusting mechanism can absorb the energy of the vibration, reducing their impact on the binding belt 2 and the storage bottle, thereby protecting the safety of the storage bottle.

[0065] In addition, the setting of the elastic adjusting mechanism can to some extent alleviate the stress concentration of the binding belt 2 during the fastening process, thereby improving the service life of the storage bottle mounting frame.

[0066] The bottle storage frame according to some embodiments of the present disclosure, as shown in FIG. 5, the adjusting mechanism 23 comprises an adjusting rod 232 and an adjusting hole 233.

[0067] The adjusting rod 232 is rotationally connected to one of the two adjacent binding sections. The adjusting hole 233 is provided on the other binding section, and the adjusting rod 232 is fitted in the adjusting hole 233. The elastic member 231 is located on the binding section provided with the adjusting hole 233, and the elastic member 231, the binding section, and the adjusting rod 232 are connected.

[0068] The adjusting rod 232 serves as an adjusting tool. By rotating the adjusting rod 232, the relative position between the two adjacent binding sections can be changed, thereby adjusting the size of the circular opening of the binding belt 2.

[0069] The adjusting hole 233 is shaped and sized to match the adjusting rod 232, so as to ensure that the adjusting rod 232 can be smoothly inserted and rotated in the adjusting hole 233. The adjusting hole 233 provides a movement track for the adjusting rod 232. By rotating the adjusting rod 232 in the adjusting hole 233, the relative position change between the binding sections can be controlled.

[0070] In some embodiments, as shown in FIG. 5, the end of the binding section corresponding to the adjusting rod 232 is provided with a through hole 211. A connecting shaft 212 is provided in the through hole 211, the connecting shaft 212 crosses the through hole 211, and the side surface of the connecting shaft 212 is provided with a connecting hole 2120 matched with the adjusting rod 232. The adjusting rod 232 is fitted on the connecting shaft 212 through the connecting hole 2120. The adjusting rod 232 is provided with a connecting nut 2321 located on the side of the adjusting rod 232 away from the elastic member 231. Through this structure, the rotational connection between the adjusting rod 232 and the binding section can be achieved. At the same time, by tightening or loosening the connecting nut 2321, the connection tightness between the adjusting rod 232 and the corresponding binding section can be adjusted.

[0071] The elastic member 231 provides an elastic force. When the binding belt 2 is fastened, the elastic force provided by the elastic member 231 provides a continuous and stable force between the two binding sections. This force not only ensures the stable connection between the two binding sections, but also ensures the close fit between the binding belt 2 and the bottle.

[0072] Specifically, when the bottle is subjected to vibration, due to the action of this external force, a slight looseness may occur between the binding belt 2 and the bottle. The elastic member 231 can quickly respond to this looseness. It releases an elastic force acting on the binding belt 2, thereby forming an inward pulling force. This pulling force can quickly reduce the distance between the two binding sections, and re-tightly fit the binding belt 2 on the bottle. Therefore, the elastic member 231 can effectively resist the micro displacement caused by vibration, and ensure that the bottle remains stable during long-term use.

[0073] In addition, the elastic member 231 can also be self-adapted to the actual force of the bottle. If the looseness caused by the vibration is small, the elastic force released by the elastic member 231 is also small; if the looseness is large, the elastic member 231 will release a larger elastic force to compensate. The self-adaptive adjustment capability improves the reliability of the bottle mounting frame in protecting the stability of the bottle.

[0074] In some optional embodiments, as shown in FIG. 5, the adjusting mechanism 23 further comprises an adjusting nut 234. The adjusting nut 234 is threadedly connected to the adjusting rod 232, the elastic member 231 is a spring and sheaths the adjusting rod 232, one end of the elastic member 231 abuts against the adjusting nut 234 through a limiting stopper, and the other end abuts against the binding section provided with the adjusting hole 233.

[0075] Specifically, when the adjusting nut 234 is rotated to approach the other binding section, the space provided by the spring for the adjusting rod 232 gradually shortens. Since the spring is in a compressed state, it will be compressed by the compression force from the adjusting nut 234. This compression causes the relative positions of the two binding sections to approach each other, the circumference of the binding belt 2 becomes shorter, and the tightening of the bottle is achieved. In this process, the spring is compressed and stores elastic potential energy. This elastic potential energy is the energy accumulated by the adjusting mechanism 23 to resist external forces. Once the external force tries to loosen the binding belt 2, the spring releases the stored elastic potential energy to help the binding belt 2 return to the tightened state, ensuring the stability and safety of the bottle.

[0076] Due to the threaded connection between the adjusting nut 234 and the adjusting rod 232, the operator can accurately control the tightening degree of the binding belt 2 by simply rotating the adjusting nut 234. This adjusting method is not only convenient and easy to use, but also can provide sufficient adjustment range to adapt to bottles of different sizes and shapes. At the same time, different compression amounts of the elastic member 231 can be set according to different bottle sizes, weights and expansion amounts.

[0077] In some optional embodiments, as shown in FIG. 5, the adjusting hole 233 is a long hole. This setting is to adapt to the circumferential shortening of the binding belt 2 during the adjustment of the tightness.

[0078] Since the binding belt 2 is usually wrapped around an object such as a bottle, when the tightness of the binding belt 2 needs to be adjusted, the binding belt 2 will be shortened or lengthened along its circumferential direction. At this time, the adjusting rod 232 needs to be able to move along the radial direction of the binding belt 2. Therefore, the long hole shape of the adjusting hole 233 can adapt to the position change of the adjusting rod 232 to avoid interference.

[0079] The length of the long hole can be set according to the range of shortening or lengthening of the binding belt 2 to ensure smooth movement of the adjusting rod 232 during adjustment and ensure the use of the bottle mounting frame 10.

[0080] In some optional embodiments, the inner side wall of the adjusting hole 233 is provided with a lubricating film layer. The lubricating film forms a separation layer on the inner side wall of the adjusting hole 233, reduces the frictional resistance when the adjusting rod 232 slides in the adjusting hole 233, and thus improves the smoothness and efficiency of the adjustment.

[0081] In addition, the lubricating film layer also has the effect of preventing wear and tear and prolonging the service life. Whether the adjusting rod 232 slides in the adjusting hole 233 or the adjusting rod 232 collides in the adjusting hole 233 due to external force, when the two directly contact, wear and tear is easy to occur, at this time, the lubricating film layer can reduce wear and tear, protect the surface of the adjusting rod 232 and the inner side wall of the long hole from being damaged, and thus prolong the service life of the entire adjusting mechanism 23.

[0082] Optionally, the lubricating film layer can be a metal layer, a non-metal layer, and a polymer layer, etc. For example, the metal layer includes a molybdenum disulfide material layer; the non-metal layer includes a polytetrafluoroethylene PTFE-based composite material layer; the polymer layer includes an epoxy resin layer, etc. The lubricating film layer of these materials can operate under high temperature and high load, and is not easy to age.

[0083] According to the bottle storage frame 10 of the vehicle-mounted hydrogen system according to some embodiments of the present disclosure, the binding belt 2 is provided with an extension fixing plate 24 extending along the axial direction of the binding belt 2, and the skin side plate 12 is fixedly connected to the extension fixing plate 24. By arranging the extension fixing plate 24 extending along the axial direction, the contact area between the skin side plate 12 and the binding belt 2 can be increased, so that the skin side plate 12 can cover a larger bottle storage area, thereby providing more comprehensive and effective protection. This not only enhances the safety of the bottle storage, but also improves the stability and reliability of the entire vehicle-mounted hydrogen system 100.

[0084] In some optional embodiments, the extension fixing plate 24 is arranged near the upper edge of the skin side plate 12, and the upper edge of the skin side plate 12 is arranged to be suspended except for being connected to the binding belt 2. The extension fixing plate 24 enables the upper part of the skin side plate 12 to closely fit on the bottle, effectively protecting the side of the bottle. This avoids the problem that the upper part of the skin side plate 12 may sag due to gravity or other factors, thereby possibly weakening the protection effect.

[0085] The upper end of the skin side plate 12 forms a curved section 14 gradually extending upward toward the binding belt 2.

[0086] In this way, the curved section 14 extends toward the direction of the bottle, so that the skin side plate 12 can more effectively wrap the bottle, increase the protection area of the skin side plate 12 to the bottle, and improve the stability of the bottle in the vehicle-mounted hydrogen system 100.

[0087] At the same time, the curved section 14 also improves the adaptability to the bottle with a self-adjustable diameter.

[0088] In some optional embodiments, when it is necessary to view or maintain the storage bottle 20, the skin side plate 12 can be flexibly lifted down simply by unfastening the connection between the binding belt 2 and the skin side plate 12. Such design not only facilitates the viewing of the surface appearance of the storage bottle 20, but also avoids the disassembly of the entire protective skin 1, improving the convenience of maintenance.

[0089] According to the second aspect of the present disclosure, the vehicle-mounted hydrogen system 100 comprises a storage bottle 20 and a storage bottle mounting frame 10 of the vehicle-mounted hydrogen system. The storage bottle mounting frame 10 of the vehicle-mounted hydrogen system adopts the storage bottle mounting frame 10 of the vehicle-mounted hydrogen system of the first aspect of the present disclosure, and the binding belt 2 is sleeved to fix the storage bottle. The side of the storage bottle is protected by the skin side plate 12, and the bottom is protected by the skin bottom plate 11, improving the safety of the storage bottle and further improving the reliability of the vehicle-mounted hydrogen system 100.

[0090] According to the third aspect of the present disclosure, the vehicle comprises a vehicle body longitudinal beam and a vehicle-mounted hydrogen system 100. The vehicle-mounted hydrogen system 100 is installed on one side of the vehicle body longitudinal beam.

[0091] Specifically, the vehicle-mounted hydrogen system 100 is installed on one side of the vehicle body longitudinal beam, and the other side is used to install other important components such as battery modules and the like. Such layout can improve the load balance of the vehicle, so that the weight distribution of the left and right of the vehicle is uniform, thereby optimizing the handling performance and driving stability of the vehicle and improving the safety of the vehicle.

[0092] Next, referring to FIGS. 1-5, the storage bottle mounting frame according to one specific embodiment of the present disclosure is described.

[0093] Referring to FIG. 1, the storage bottle mounting frame comprises a protective skin 1, a binding belt 2 and a support rod 3.
