In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0032] Existing rail transit vehicles are usually powered by catenary or on-board energy storage devices. One form of on-board energy storage power supply is to use energy storage devices such as power batteries or supercapacitors in conjunction with hydrogen energy systems as the power source for driving the vehicle. Under high endurance requirements, the hydrogen energy system and energy storage device are large in size, and the existing carriage space is small. If the hydrogen energy system, energy storage device and other necessary vehicle equipment are to be placed in the carriage, the passenger space of the existing carriage needs to be reduced, resulting in low space utilization of the carriage. In related technologies, a carriage that is longer than the existing carriage can be designed to increase the space of the carriage so that the carriage can accommodate the hydrogen energy system, energy storage device and other necessary vehicle equipment while still having a large passenger space. However, the above method requires the carriage to be redesigned, the modification cost is high, and the practicality is low.

[0033] Based on this, refer to Figure 1 The hydrogen energy powered rail vehicle group provided by the embodiment of the present invention includes a power vehicle module 100 and an equipment vehicle module 200. Figure 5 and Figure 9 The power vehicle module 100 includes a power compartment 110 and an energy storage device 120. The interior of the power compartment 110 has a passenger space, and the energy storage device 120 is located outside the passenger space. Specifically, the energy storage device 120 can be a power battery or a supercapacitor; Figures 2 to 4 、 Figures 6 to 8 The equipment vehicle module 200 includes an equipment compartment 210 and a hydrogen energy system 220. The hydrogen energy system 220 is installed in the equipment compartment 210 and is at least partially located inside the equipment compartment 210. The equipment compartment 210 is connected to the power compartment 110. The hydrogen energy system 220 is used to supply power to the power vehicle module 100.

[0034] The hydrogen energy powered rail vehicle group provided by the embodiment of the present invention is provided with a power vehicle module 100 and an equipment vehicle module 200. The energy storage device 120 in the power vehicle module 100 is located outside the passenger space of the power vehicle compartment 110. The equipment vehicle module 200 includes an equipment vehicle compartment 210 and a hydrogen energy system 220. The hydrogen energy system 220 is installed in the equipment vehicle compartment 210. The hydrogen energy system 220 and the energy storage device 120 are both located outside the passenger space and do not occupy the passenger space, which is conducive to improving the space utilization of the compartment; moreover, the equipment vehicle module 200 is independent of the power vehicle module 100. In actual application, the equipment vehicle module 200 can be added on the basis of the original power vehicle compartment 110 without the hydrogen energy system 220, and the energy storage device 120 can be arranged on the power vehicle compartment 110 to form the hydrogen energy powered rail vehicle group provided by the embodiment of the present invention. There is no need to remanufacture the power vehicle module 100, which is conducive to reducing the modification cost and improving the practicality.

[0035] Further, refer to Figure 1The power car module 100 is provided with two power cars 110, and the two power cars 110 are respectively connected to the two ends of the equipment car 210. The equipment car module 200 includes two hydrogen energy systems 220, which are used to provide power to the two power car modules 100 in a one-to-one correspondence. The two power car modules 100 share one equipment car module 200. In actual application, an equipment car module 200 is added between the two original power cars 110. The two hydrogen energy systems 220 installed in one equipment car module 200 can respectively supply power to the two power cars 110, which is conducive to reducing the number of equipment car modules 200 in the entire train. On the one hand, it can reduce the number of train sets and reduce the complexity of vehicle set formation. On the other hand, compared with using two equipment cars 210 to install two hydrogen energy systems 220, using one equipment car 210 to install two hydrogen energy systems 220 has lower manufacturing costs, thereby further reducing the cost of transformation.

[0036] Further, refer to Figures 2 to 4 、 Figures 6 to 8 The hydrogen energy system 220 includes a hydrogen fuel cell device 221 and a hydrogen storage device 222. The hydrogen storage device 222 is used to provide hydrogen to the hydrogen fuel cell device 221, and the hydrogen fuel cell device 221 is used to supply power to the power vehicle module 100. The layout of the two hydrogen fuel cell devices 221 and the two hydrogen storage devices 222 in the equipment compartment 210 can be set according to actual needs. For example:

[0037] In some embodiments, reference Figures 2 to 4 The two hydrogen storage devices 222 are both housed within the equipment compartment 210 and are arranged at a set of diagonal locations within the equipment compartment 210. The two hydrogen fuel cell devices 221 are both mounted on the top of the equipment compartment 210 and are symmetrically arranged about a central axis of the top of the equipment compartment 210. The other set of diagonal locations of the equipment compartment 210 can be used to respectively place the electrical cabinets of the two power vehicle modules 100 and other necessary vehicle equipment. The two hydrogen fuel cell devices 221 are arranged symmetrically on the top of the equipment compartment 210, and the two hydrogen storage devices 222 and the electrical cabinets of the two power vehicle modules 100 and other necessary vehicle equipment are arranged symmetrically within the center of the equipment compartment 210. This helps to improve the uniformity of the weight distribution of the equipment vehicle module 200, making the equipment vehicle module 200 more balanced and reducing the possibility of the equipment vehicle module 200 being tilted after being mounted on the track beam 300, thereby improving the operational stability of the equipment vehicle module 200.

[0038] In other embodiments, referring to Figures 6 to 8The two hydrogen storage devices 222 are both housed inside the equipment compartment 210 and are respectively arranged at a set of diagonal positions inside the equipment compartment 210. The two hydrogen fuel cell devices 221 are both housed inside the equipment compartment 210 and are respectively arranged at another set of diagonal positions inside the equipment compartment 210. The electrical cabinets of the two power car modules 100 and other necessary vehicle equipment can be arranged symmetrically on the top of the equipment compartment 210 and about a central axis of the top of the equipment compartment 210. The two hydrogen fuel cell devices 221 and the two hydrogen storage devices 222 are arranged symmetrically inside the center of the equipment compartment 210, and the electrical cabinets of the two power car modules 100 and other necessary vehicle equipment are arranged symmetrically on the top of the equipment compartment 210. This helps to improve the uniformity of the weight distribution of the equipment car module 200, making the equipment car module 200 more balanced and reducing the possibility of the equipment car module 200 being deflected after being installed on the track beam 300, thereby improving the operational stability of the equipment car module 200.

[0039] Further, refer to Figures 2 to 4 、 Figures 6 to 8 The hydrogen energy system 220 further includes a second heat sink 223, which is used to dissipate heat for the hydrogen fuel cell device 221. The second heat sink 223 and the hydrogen fuel cell device 221 are arranged at the same position. For example, referring to Figures 2 to 4 , the second heat sink 223 and the hydrogen fuel cell device 221 can be simultaneously arranged on the top of the equipment compartment 210; Figures 6 to 8 The second heat sink 223 and the hydrogen fuel cell device 221 can also be simultaneously disposed in the equipment accommodating space 211 inside the equipment compartment 210 .

[0040] Further, refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 8 The interior of the equipment carriage 210 has an equipment accommodating space 211 and a through space 212 that are isolated from each other. The equipment accommodating space 211 is used to accommodate the hydrogen energy system 220. The through space 212 runs through the equipment carriage 210 to connect the passenger spaces of the two power carriages 110. The through space 212 is used for passengers to move between the two power carriages 110, which is beneficial to improving the integrity of the interior space of the hydrogen energy powered rail vehicle group.

[0041] Further, refer to Figure 9 The energy storage device 120 is connected to the top of the power car 110, and the energy storage device 120 is not blocked by other components. Therefore, the maintenance operation of the energy storage device 120 is relatively simple, which is conducive to reducing the maintenance cost of the hydrogen-powered rail vehicle group.

[0042] Further, refer to Figure 1 、 Figure 5and Figure 9 The power vehicle module 100 further includes a power bogie 130, which is connected to the top of the power vehicle 110 and is mounted on the track beam 300. The energy storage device 120 and the hydrogen energy system 220 are both used to drive the power bogie 130 to move relative to the track beam 300. The power bogie 130 is connected to the top of the power vehicle 110, does not occupy passenger space, and is mounted on the track beam 300, enabling it to run smoothly along the track beam 300, thereby improving the operational stability of the hydrogen-powered rail vehicle group.

[0043] Further, refer to Figure 1 、 Figure 5 and Figure 9 The power car module 100 also includes a mobile car 140, which is used to be installed on the track beam 300. The energy storage device 120 is housed inside the mobile car 140, and the mobile car 140 is connected to the power bogie 130, so that during the operation of the hydrogen energy powered rail vehicle group, the mobile car 140 can move synchronously with the power bogie 130 to ensure the stability of power supply. The energy storage device 120 is installed in the mobile car 140, and the mobile car 140 is installed on the track beam 300, which can save space on the top of the power car 110; and the energy storage device 120 is electrically connected to the power bogie 130 installed in the track beam 300. It is understandable that the wires between the energy storage device 120 and the power bogie 130 can also be laid in the track beam 300, which helps to reduce the difficulty of wiring.

[0044] Further, refer to Figure 1 、 Figure 5 and Figure 9 The power vehicle module 100 further includes a first heat sink 150, which is used to dissipate heat from the energy storage device 120. The first heat sink 150 and the energy storage device 120 are installed at the same position. For example, Figure 1 and Figure 5 , the first heat sink 150 and the energy storage device 120 are both installed in the mobile vehicle 140; Figure 9 The first heat sink 150 and the energy storage device 120 are both installed on the top of the power compartment 110 .

[0045] Further, refer to Figure 1 、 Figure 5 and Figure 9Two power bogies 130 are provided, one on each side of the mobile vehicle 140 in the direction in which the track beam 300 extends. The two power bogies 130 can jointly bear the weight of the power carriage 110, thereby reducing the weight borne by a single power bogie 130, lowering the possibility of damage to the single power bogie 130 due to excessive force, and improving the structural stability of the hydrogen-powered rail vehicle set. Furthermore, with the reduced weight borne by a single power bogie 130, the load-bearing capacity requirement of the single power bogie 130 is also reduced accordingly, which helps reduce the manufacturing cost of the single power bogie 130 and makes the hydrogen-powered rail vehicle set more economical and practical.

[0046] In some embodiments, reference Figure 1 、 Figure 5 and Figure 9 In the power vehicle module 100 provided with two power bogies 130, the mobile vehicle 140 is only connected to one of the power bogies 130. The mobile vehicle 140 and the power bogie 130 can be rigidly connected by a rigid rod or other structure, or elastically connected by an elastic connecting rod or other structure. By driving the mobile vehicle 140 along the track beam 300 by one of the power bogies 130, the synchronous movement of the mobile vehicle 140 and the power bogie 130 can be achieved.

[0047] In other embodiments, in a power vehicle module 100 provided with two power bogies 130, a mobile vehicle 140 may also be provided to be simultaneously connected to the two power bogies 130. However, during the operation of the hydrogen energy powered rail vehicle group, the distance between the two power bogies 130 is not constant. Therefore, when the mobile vehicle 140 is simultaneously connected to the two power bogies 130, the mobile vehicle 140 and the power bogies 130 should be elastically connected through structures such as elastic connecting rods to ensure the stability of operation.

[0048] Further, refer to Figures 1 to 4 、 Figures 6 to 8 The equipment car module 200 further includes a non-powered bogie 230, which is connected to the equipment car 210 and is used to be mounted on the track beam 300. The non-powered bogie 230 can share the weight of the entire hydrogen-powered rail vehicle group with the powered bogie 130 in the power car module 100, which helps to further reduce the weight borne by a single powered bogie 130, reduces the possibility of a single powered bogie 130 being damaged by excessive force, and improves the structural stability of the hydrogen-powered rail vehicle group. In addition, after the weight borne by a single powered bogie 130 is reduced, the load-bearing capacity requirement of the single powered bogie 130 is also reduced accordingly, which helps to reduce the manufacturing cost of the single powered bogie 130, making the hydrogen-powered rail vehicle group more economical and practical.

[0049] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
