Description

Technical Field

[0001] This utility model belongs to the field of hydrogen energy vehicles, and more specifically, it relates to a hydrogen swapping on-board hydrogen supply system installed on both sides of the chassis. Background Technology

[0002] Driven by the global goal of carbon neutrality, hydrogen-powered heavy-duty trucks, with their advantages of zero emissions and long-range heavy-duty operation, have become a core direction for the zero-carbon transformation of commercial vehicles. The National Medium and Long-Term Plan for the Development of the Hydrogen Energy Industry (2021-2035) explicitly lists it as a priority demonstration area. Currently, hydrogen-powered heavy-duty trucks have been piloted on a large scale in scenarios such as port logistics, but they face two major bottlenecks: First, there is a lack of hydrogen refueling infrastructure. The layout of hydrogen refueling stations across the country is concentrated and the growth rate is slowing down, making it difficult to support cross-regional logistics needs. Second, the efficiency of refueling is limited. Although the traditional hydrogen refueling mode is better than charging electric heavy-duty trucks, it is still limited by the distribution of hydrogen refueling stations. Although there have been breakthroughs in technologies such as high-pressure gaseous hydrogen storage and liquid hydrogen storage and transportation, the problem of adapting to scenarios for rapid refueling has not been solved.

[0003] Existing hydrogen swapping vehicle-mounted hydrogen supply system technology is only applicable to models with the on-board hydrogen supply system located at the rear of the vehicle or similar layouts. However, in addition to the rear of the vehicle, hydrogen supply systems in hydrogen-powered heavy-duty trucks are also located on both sides of the chassis, and this accounts for a significant proportion of the market.

[0029] Reference Figures 1 to 5 As shown, a hydrogen swapping vehicle-mounted hydrogen supply system installed on both sides of the chassis is provided, including two hydrogen system fixing modules 1 fixed to both sides of the vehicle chassis. Both hydrogen system fixing modules 1 are detachably connected to hydrogen cylinder modules 2. The bottoms of the two hydrogen cylinder modules 2 are fixedly connected by connecting beams 3. Each hydrogen system fixing module 1 is fixedly installed on both sides of the vehicle chassis by bolts.

[0030] Preferably, the hydrogen system fixing module 1 and the hydrogen cylinder module 2 are connected by positioning holes and are equipped with guide bushings to guide the installation of the hydrogen cylinder module 2.

[0031] In some embodiments of this utility model, each hydrogen system fixing module 1 includes a support beam 11, a fixing sub-beam 12, and a fixing main beam 13. The support beam 11, the fixing sub-beam 12, and the fixing main beam 13 are welded together to form a fixing frame. A fixing plate 14 is fixedly installed on the outside of the fixing frame. Bolt holes for fixing to the vehicle chassis are opened on the fixing sub-beam 12, the fixing main beam 13, and the fixing plate 14.

[0032] Furthermore, a hydrogen system connector 15 is connected to the bottom of the support beam 11.

[0033] Furthermore, a guide positioning bushing 16 is interference-fitted to the bottom of the support beam 11.

[0034] Furthermore, an outer skin 17 is fixedly connected to the outer periphery of the fixed frame to protect the hydrogen cylinder module 2.

[0035] In some embodiments of this utility model, the hydrogen cylinder module 2 includes a hydrogen cylinder 22 and a hydrogen cylinder fixing frame 23. A hydrogen cylinder strap 21 is fixedly connected to the hydrogen cylinder fixing frame 23. The hydrogen cylinder 22 is fixedly mounted on the hydrogen cylinder fixing frame 23 by the hydrogen cylinder strap 21. A placement beam 231 is provided on the hydrogen cylinder fixing frame 23. The hydrogen cylinder strap 21 is located in the middle of the placement beam 231. Guide positioning pins 24 are located at both ends of the placement beam 231.

[0036] Furthermore, the connecting assembly 25 includes a guide block 251, a guide bushing 252, and a fixing bend 253. The fixing bend 253 has a U-shaped structure. The guide block 251 is fixedly installed inside the fixing bend 253 by bolts.

[0037] Preferably, the connecting component 25 has a bolt through hole 254, and the bolt through hole 254 has a chamfer to guide the fixing bolt to be screwed in.

[0039] Preferably, the strap body 211 is made of stainless steel to extend its service life.

[0040] In this embodiment, the system consists of a hydrogen system fixing module 1 (fixed to both sides of the chassis), a quick-change hydrogen cylinder module 2, and a connecting beam 3. The hydrogen system fixing module 1 and the hydrogen cylinder module 2 are fixed together with bolts. The left and right hydrogen cylinder modules 2 are connected by the connecting beam 3. The hydrogen system fixing module 1 is fixed to both sides of the vehicle chassis with bolts. Then, the hydrogen cylinder module 2 is detachably connected to the hydrogen system fixing module 1. The guide positioning bushing 16 and the guide positioning pin 24 guide and position the hydrogen cylinder module 2 and the hydrogen system fixing module 1 to cooperate. At the same time, the connecting beam 3 connects the two hydrogen cylinder modules 2 into one unit. When disassembling and replacing, both hydrogen cylinder modules 2 need to be disassembled and replaced together, which can quickly disassemble and assemble the hydrogen fuel cell vehicle, thereby quickly replenishing energy.

[0041] The hydrogen system fixing module 1 is fixed to both sides of the vehicle chassis with bolts. The connection end face of the fixing module 1 and the hydrogen cylinder module 2 is designed with positioning holes and equipped with guide bushings to guide the installation of the hydrogen cylinder module 2.

[0042] like Figure 2 As shown, the hydrogen system fixing module 1 consists of a support beam 11, a fixing sub-beam 12, a fixing main beam 13, a fixing plate 14, a hydrogen system connecting seat 15, a guide positioning bushing 16, and an outer skin 17. The fixing frame is integrally welded. The fixing sub-beam 12, the fixing main beam 13, and the fixing plate 14 have bolt holes for fixing to the vehicle chassis. The bottom surface of the hydrogen system connecting seat 15 is flush with the bottom surface of the support beam 11 and is welded with a welding nut to cooperate with the hydrogen cylinder module 2 for fixing. The guide positioning bushing 16 and the support beam 11 adopt an interference fit to ensure positioning accuracy.

[0043] like Figures 3-5 As shown, the hydrogen cylinder module 2 consists of a hydrogen cylinder strap 21, a hydrogen cylinder 22, a fixing frame 23, a guide positioning pin 24, and a connecting component 25; the hydrogen cylinder strap 21 consists of a stainless steel strip 211, a locking bolt 212, a strap buckle 213, and an anti-slip pad 214; the connecting component 25 consists of a guide block 251, a guide bushing 252, and a fixing bend 253.

[0044] Hydrogen cylinder straps 21 secure the hydrogen cylinder 22 to the fixed frame 23. Guide positioning pins 24 provide positioning and guidance during the engagement of the hydrogen cylinder module 2 with the hydrogen system fixing module 1, helping the quick-change hydrogen cylinder module 2 to align with the correct fixing point. The fixing bolts pass through the bolt holes in the connecting assembly 25 and then engage with the welded nuts on the hydrogen system connecting seat 15. The connecting assembly 25 is designed with chamfers to guide the fixing bolt path. Furthermore, to further ensure the accuracy of the fixing bolt path, the connecting assembly 25 is also designed with guide bushings 252, which can engage with the guide positioning pins of the tightening / untiling bolt mechanism of the hydrogen system disassembly / removal mechanism (not shown in this system).

[0045] At the bottom of the fixed frame 23, that is, below the base where the hydrogen cylinder strap 21 is fixed, there is a guide bushing, which helps to guide the connection between the hydrogen system disassembly and assembly mechanism and the hydrogen cylinder module 2.

[0046] When replacing the hydrogen system, the hydrogen system disassembly and assembly mechanism, guided by the guide bushing below the hydrogen system, first aligns with the hydrogen system, then removes the fixing bolts of the hydrogen system to be replaced, thus removing the hydrogen system. When installing the hydrogen system, the disassembly and assembly mechanism first transports the new hydrogen system to the underside of the vehicle chassis. Guided by the positioning guide bushing 16, the hydrogen system is slowly raised until it is aligned with the hydrogen system fixing module 1, i.e., the guide positioning pin 24 is fully inserted into the positioning guide bushing 16. Then, the fixing bolts of the hydrogen system are screwed in through the bolt tightening / removing mechanism of the disassembly and assembly mechanism, thereby completing the replacement of the hydrogen system.

[0047] The above is a further detailed description of this utility model and should not be considered as a limitation on the specific implementation of this utility model. For those skilled in the art, simple deductions or substitutions without departing from the concept of this utility model are all within the protection scope of this utility model.
