Description

Technical Field

[0001] This invention relates to the technical field of industrial loading and unloading equipment, and more specifically, to a modular hydrogen fuel cell front-end crane with separate electric and hydrogen compartments. Background Technology

[0002] As hydrogen energy technology matures, its application scope is expanding. From the widespread adoption of small, light-duty vehicles to the initial trials in large, heavy-duty vehicles, not only has the power output of the fuel cell system's combustion module increased, but the hydrogen storage capacity of the hydrogen supply module has also grown significantly. Due to the compact layout and low energy consumption of small, light-duty vehicles, their hydrogen fuel cell systems are small in size, have low power output, and limited hydrogen storage, resulting in an integrated architecture. Currently, with the widespread and mature application of hydrogen energy technology, it is gradually being extended to large, heavy-duty vehicles. Large, heavy-duty vehicles have higher power requirements for their hydrogen fuel cell systems, typically using high-voltage power supply, which poses greater safety risks and necessitates significantly higher safety standards. Furthermore, due to the higher energy consumption of heavy-duty vehicles, a sufficiently large hydrogen storage capacity is required to ensure continuous operation. If a high-power, high-hydrogen-capacity hydrogen fuel cell system still uses an integrated architecture, the integrated combustion module, hydrogen supply module, and energy storage module will be large in size, making installation, layout, and maintenance on the vehicle more difficult. Therefore, optimizing the design of hydrogen fuel cell systems while ensuring the safety performance of heavy-duty vehicles has become an urgent problem to be solved. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a modular front-end gantry for hydrogen fuel cells with separate electric and hydrogen storage, which not only has high safety performance, but also offers high convenience for the installation and maintenance of hydrogen fuel cell systems.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The present invention relates to a modular hydrogen fuel cell front-end mounting system with separate hydrogen and electric power components, comprising: a frame including a first mounting portion and a second mounting portion disposed opposite to each other in its width direction; a fuel cell module configured to convert hydrogen energy into electrical energy; the fuel cell module being disposed on the first mounting portion; a hydrogen supply module configured to supply hydrogen to the fuel cell module; the hydrogen supply module being disposed on the second mounting portion; and an energy storage module disposed on the first mounting portion, and spaced apart from the fuel cell module; the energy storage module being electrically connected to the fuel cell module to store the electrical energy generated by the fuel cell module.

[0008] A hydrogen storage tank, which is fixedly installed in the first mounting frame;

[0009] A gas transmission pipeline is provided, which connects the hydrogen storage tank and the fuel cell module to allow hydrogen from the hydrogen storage tank to flow into the fuel cell module.

[0010] The distance between the center of gravity of the hydrogen supply module and the vehicle frame is greater than the distance between the fuel cell module and the vehicle frame; and / or, the distance between the center of gravity of the hydrogen supply module and the vehicle frame is greater than the distance between the energy storage module and the vehicle frame.

[0011] In some embodiments, the gas transmission pipeline includes a first section, a second section, and a third section; one end of the first section is connected to the hydrogen storage tank, and the other end of the first section is connected to one end of the second section, the first section being disposed on the vehicle frame and extending toward the rear of the vehicle frame; the second section being disposed on the rear of the vehicle frame, and the other end of the second section being connected to one end of the third section; the third section being disposed on the vehicle frame, and the other end of the third section being connected to the fuel cell module.

[0012] In some embodiments, the electro-hydrogen split modular hydrogen fuel cell front-end hanger further includes:

[0013] A first housing is disposed on the second mounting portion and covers the outside of the hydrogen supply module;

[0014] The second housing is disposed on the first mounting part and covers the outside of the fuel cell module and the energy storage module.

[0015] The first housing is provided with a first hydrogen concentration sensor, which is configured to detect the hydrogen concentration inside the first housing; the second housing is provided with a second hydrogen concentration sensor, which is configured to detect the hydrogen concentration inside the second housing.

[0016] In some embodiments, a valve body is provided at the hydrogen outlet of the hydrogen supply module. The valve body is configured to control the hydrogen outlet to close when the hydrogen concentration in the first housing or the hydrogen concentration in the second housing is greater than or equal to a preset threshold.

[0017] In some embodiments, the first housing is provided with a first vent; a first fan is provided at the first vent, and the first fan is configured to cause air inside the first housing to be discharged to the outside through the first vent;

[0018] The second housing is provided with a second vent; a second fan is provided at the second vent, the second fan being configured to cause air inside the second housing to be discharged to the outside through the second vent; and / or,

[0019] The first vent is located on the side of the first housing away from the second housing in the width direction of the frame; the second vent is located on the side of the second housing away from the first housing in the width direction of the frame.

[0020] In some embodiments, the energy storage module includes a second mounting frame and a battery pack, wherein the second mounting frame is disposed on the first mounting portion; and the battery pack is fixedly disposed on the second mounting frame.

[0021] The fuel cell module includes a third mounting frame and a fuel cell engine. The third mounting frame is disposed on the first mounting part and is spaced apart from the second mounting frame. The fuel cell engine is fixedly disposed on the third mounting frame.

[0022] In some embodiments, the energy storage module further includes a temperature sensor connected to the battery pack; the temperature sensor is configured to detect the temperature of the battery pack.

[0023] In some embodiments, the fuel cell module further includes a cooling assembly and an exhaust assembly; the cooling assembly is connected to the fuel cell engine and configured to cool the fuel cell engine; the exhaust assembly is connected to the exhaust port of the fuel cell engine and configured to guide the exhaust gas generated by the fuel cell engine to the outside.

[0024] In some embodiments, the front-end crane of the electro-hydrogen split modular hydrogen fuel cell is a front-end crane.

[0025] The present invention relates to a modular hydrogen fuel cell front-end crane with separate electric and hydrogen components. The crane's frame has a first mounting portion and a second mounting portion in its width direction. In this embodiment, the fuel cell module and energy storage module are both mounted on the first mounting portion, while the hydrogen supply module is mounted on the second mounting portion. Because the first and second mounting portions are positioned opposite each other, the hydrogen supply module is spaced apart from the fuel cell module and energy storage module, distributed on both sides of the frame in the width direction. This isolates the high-voltage components formed by the fuel cell module and energy storage module from the hydrogen supply module, thus solving the safety risk problem caused by the integrated architecture of the high-voltage components and the hydrogen supply module in related technologies, and improving safety. Furthermore, the modular mounting of the fuel cell module, energy storage module, and hydrogen supply module on the frame facilitates separate installation, removal, and maintenance of each module, thereby improving the ease of installation and maintenance of the fuel cell module, hydrogen supply module, and energy storage module in the modular hydrogen fuel cell front-end crane of this embodiment.

[0026] Furthermore, since the fuel cell module, energy storage module, and hydrogen supply module are respectively mounted on the first mounting part and the second mounting part of the modular hydrogen fuel cell front-end crane of this embodiment, the weight of the fuel cell module, energy storage module, and hydrogen supply module is more evenly distributed on both sides of the frame in the width direction, so that the weight distribution on both sides of the modular hydrogen fuel cell front-end crane of this embodiment is uniform, thereby improving the stability of the modular hydrogen fuel cell front-end crane when it is in motion.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] In related technologies, vehicles with hydrogen fuel cell systems include a fuel cell module, a hydrogen supply module, and an energy storage module, all integrated into a single architecture. When the vehicle is a modular hydrogen fuel cell front-end crane with a separate hydrogen and fuel cell unit, high-voltage power supply is typically used, posing significant safety risks. For example, in these technologies, the hydrogen refueling structure for the hydrogen supply module and the charging structure for the energy storage module are integrated into the overall architecture of the hydrogen fuel cell system. These components are prone to micro-leakage under long-term vibration or sealing aging. Furthermore, the energy storage module (such as a lithium-ion battery or supercapacitor) may generate localized high temperatures, arcs, or sparks during charging and discharging due to internal resistance heating, potentially leading to safety accidents. Moreover, the integrated architecture of the fuel cell module, hydrogen supply module, and energy storage module not only limits the space available for installation and maintenance but also creates a complex overall structure, making the installation and maintenance of hydrogen fuel cell systems in these vehicles difficult.

[0046] To address the aforementioned issues, this invention proposes a front-end suspension 10 for a modular hydrogen fuel cell with separate electric and hydrogen storage.

[0047] The following description, with reference to the accompanying drawings, describes an embodiment of the present invention: a modular hydrogen fuel cell front-end suspension 10 with separate electric and hydrogen storage.

[0048] like Figures 1-7 As shown, the modular hydrogen fuel cell front-end crane 10 with separate electric and hydrogen components according to an embodiment of the present invention includes a frame 100, a fuel cell module 200, a hydrogen supply module 300, and an energy storage module 400.

[0049] The frame 100 includes, for example, in its width direction (e.g.) Figure 1 The first mounting portion 110 and the second mounting portion 120 are arranged opposite each other (in a left-right direction). The fuel cell module 200 is configured to convert hydrogen energy into electrical energy; that is, the fuel cell module 200 can convert the hydrogen energy of hydrogen gas into electrical energy. The fuel cell module 200 is mounted on the first mounting portion 110. The hydrogen supply module 300 is configured to supply hydrogen gas to the fuel cell module 200. The hydrogen supply module 300 is mounted on the second mounting portion 120. The energy storage module 400 is mounted on the first mounting portion 110 and is spaced apart from the fuel cell module 200. The energy storage module 400 is electrically connected to the fuel cell module 200 so that the energy storage module 400 stores the electrical energy generated by the fuel cell module 200, thereby providing power to the entire vehicle of the modular hydrogen fuel cell front-end crane 10 of this embodiment.

[0050] Compared with related technologies, the electric-hydrogen split modular hydrogen fuel cell front-end crane 10 of the present invention has a frame 100 with a first mounting part 110 and a second mounting part 120 in its width direction. The fuel-power module 200 and the energy storage module 400 of the electric-hydrogen split modular hydrogen fuel cell front-end crane 10 of this embodiment are both disposed on the first mounting part 110, and the hydrogen supply module 300 is disposed on the second mounting part 120. Because the first mounting part 110 and the second mounting part 120 are arranged opposite to each other, the hydrogen supply module 300 is distributed separately from the fuel cell module 200 and the energy storage module 400 on both sides of the vehicle frame 100 in the width direction. In other words, the fuel cell module 200 and the energy storage module 400 are isolated from the hydrogen supply module 300, which avoids the safety hazard of hydrogen leakage from the hydrogen supply module 300 accumulating at the electrical structures of the fuel cell module 200 and the energy storage module 400. This solves the problem of greater safety risks caused by the integrated architecture of the fuel cell module 200, the energy storage module 400 and the hydrogen supply module 300 in related technologies, and improves safety. Furthermore, the fuel cell module 200, energy storage module 400, and hydrogen supply module 300 are modularly mounted on the vehicle frame 100, which facilitates the separate installation, removal, and maintenance of the fuel cell module 200, energy storage module 400, and hydrogen supply module 300. Therefore, the ease of installation and maintenance of the fuel cell module 200, hydrogen supply module 300, and energy storage module 400 of the modular hydrogen fuel cell front-end crane 10 of the present invention is improved.

[0051] Furthermore, since the fuel cell module 200, the energy storage module 400, and the hydrogen supply module 300 are respectively mounted on the first mounting portion 110 and the second mounting portion 120 of the modular hydrogen fuel cell front-end crane 10 with separate electric and hydrogen components in this embodiment, the weight of the fuel cell module 200, the energy storage module 400, and the hydrogen supply module 300 is relatively evenly distributed on both sides of the frame 100 in the width direction. This makes the weight distribution on both sides of the modular hydrogen fuel cell front-end crane 10 with separate electric and hydrogen components in this embodiment uniform, thereby improving the stability of the modular hydrogen fuel cell front-end crane 10 with separate electric and hydrogen components during operation.

[0052] In some embodiments, such as Figure 2As shown, the hydrogen supply module 300 of this embodiment includes a first mounting frame 310, a hydrogen storage tank 320, and a gas transmission pipeline 330. The first mounting frame 310 is disposed on the second mounting part 120; the hydrogen storage tank 320 is fixedly installed in the first mounting frame 310, and the gas transmission pipeline 330 is connected between the hydrogen storage tank 320 and the fuel cell module 200, so that the hydrogen in the hydrogen storage tank 320 flows into the fuel cell module 200. That is, the hydrogen storage tank 320 can store hydrogen, and the hydrogen in the hydrogen storage tank 320 is input into the fuel cell module 200 through the gas transmission pipeline 330, so that the fuel cell module 200 converts hydrogen energy into electrical energy. Therefore, using the hydrogen storage tank 320 to store hydrogen is beneficial to increasing the hydrogen storage capacity of the hydrogen supply module 300, thereby providing sufficient power for the front-end crane 10 of the electro-hydrogen split modular hydrogen fuel cell of this embodiment.

[0053] In some embodiments, such as Figure 2 As shown, the distance between the center of gravity of the hydrogen supply module 300 and the vehicle frame 100 is greater than the distance between the fuel cell module 200 and the vehicle frame 100; and / or, the distance between the center of gravity of the hydrogen supply module 300 and the vehicle frame 100 is greater than the distance between the energy storage module 400 and the vehicle frame 100.

[0054] In other words, the distance between the center of gravity of the hydrogen supply module 300 and the vehicle frame 100 is greater than the distance between the fuel cell electric module 200 and the vehicle frame 100; or, the distance between the center of gravity of the hydrogen supply module 300 and the vehicle frame 100 is greater than the distance between the energy storage module 400 and the vehicle frame 100; or, the distance between the center of gravity of the hydrogen supply module 300 and the vehicle frame 100 is greater than the distance between the fuel cell electric module 200 and the vehicle frame 100 and the distance between the energy storage module 400 and the vehicle frame 100.

[0055] It is understandable that, because the hydrogen storage tank 320 of the hydrogen supply module 300 stores hydrogen, the overall weight of the hydrogen supply module 300 is less than that of the fuel cell module 200 and the energy storage module 400. In the above embodiment, in order to improve the stability of the front-end crane 10 of the electro-hydrogen split modular hydrogen fuel cell in this embodiment under driving or other working conditions, the distance between the center of gravity of the hydrogen supply module 300 and the frame 100 is made greater than the distance between the fuel cell module 200 and the frame 100 and / or the distance between the energy storage module 400 and the frame 100, so as to further improve the uniformity of the weight distribution on both sides of the frame 100.

[0056] Specifically, the energy storage module 400 includes a second mounting bracket 410 and a battery pack 420. The second mounting bracket 410 is disposed on the first mounting portion 110, and the battery pack 420 is fixedly disposed on the second mounting bracket 410. The battery pack 420 can be a lithium battery pack 420 or other types of battery packs 420. Thus, the battery pack 420 is fixedly mounted on the second mounting portion 120 using the second mounting bracket 410, ensuring a stable connection between the battery pack 420 and the vehicle frame 100, and the structure is simple.

[0057] The fuel cell module 200 includes a third mounting bracket (not shown in the figure) and a fuel cell engine 220. The third mounting bracket is disposed on the first mounting portion 110 and is spaced apart from the second mounting bracket 410. The fuel cell engine 220 is fixedly mounted on the third mounting bracket. Thus, the fuel cell engine 220 is fixedly mounted on the first mounting portion 110 using the third mounting bracket, ensuring a stable connection between the fuel cell engine 220 and the vehicle frame 100, and the structure is simple.

[0058] In some alternative embodiments, the second mounting bracket 410 is connected to the first mounting part 110 via a threaded connection structure, and the third mounting bracket is connected to the first mounting part 110 via a threaded connection structure.

[0059] In some alternative embodiments, the second mounting frame 410 is connected to the first mounting part 110 by welding, and the third mounting frame is connected to the first mounting part 110 by welding.

[0060] Furthermore, the second mounting frame 410 and the third mounting frame are smaller in width than the first mounting frame 310, so that the distance between the center of gravity of the hydrogen supply module 300 and the vehicle frame 100 is greater than the distance between the fuel cell module 200 and the vehicle frame 100 and the distance between the energy storage module 400 and the vehicle frame 100, thereby further improving the uniformity of the weight distribution on both sides of the vehicle frame 100.

[0061] In some embodiments, the first mounting frame 310 includes a first enclosure wall and a first base plate. The first enclosure wall is a frame structure, and the first base plate is connected to the bottom of the first enclosure wall. The second mounting frame 410 includes a second enclosure wall and a plurality of first crossbeams. The second enclosure wall is a frame structure, and the plurality of first crossbeams are connected to the bottom of the second enclosure wall. The third mounting frame includes a third enclosure wall and a plurality of second crossbeams. The third enclosure wall is a frame structure, and the plurality of second crossbeams are connected to the bottom of the third enclosure wall. The second enclosure wall and the first crossbeams, as well as the third enclosure wall and the second crossbeams, are hollow metal structures, while the first enclosure wall and the first base plate are solid metal structures. This makes the first mounting frame 310 of the hydrogen supply module 300 heavier, thereby further improving the uniformity of weight distribution on both sides of the vehicle frame 100.

[0062] In some embodiments, such as Figure 5 As shown, the gas transmission pipeline 330 includes a first section 331, a second section 332, and a third section 333. One end of the first section 331 is connected to the hydrogen storage tank 320, and the other end of the first section 331 is connected to one end of the second section 332. The first section 331 is mounted on the vehicle frame 100 and extends towards the rear 130 of the vehicle frame 100, for example, towards the rear of the vehicle frame 100. The second section 332 is mounted on the rear 130 of the vehicle frame 100, and the other end of the second section 332 is connected to one end of the third section 333. The third section 333 is mounted on the vehicle frame 100, and the other end of the third section 333 is connected to the fuel cell module 200.

[0063] It is understandable that, in this embodiment, the front of the modular hydrogen fuel cell front-end crane 10, which is designed for separate electric and hydrogen storage, is susceptible to damage during driving or other operating modes. The gas supply line 330 is located at the rear and tail 130 of the frame 100 to minimize the risk of leakage due to compression or breakage of the gas supply line 330, thereby improving the overall passive safety performance of the vehicle. Furthermore, since the gas supply line 330 is directly located on the tail 130 of the frame 100, it eliminates the need for a structure on the frame 100 for the gas supply line 330 to pass through, thus improving the overall structural strength of the frame 100. It also facilitates direct installation and maintenance of the gas supply line 330.

[0064] Furthermore, a protective shell extending along the extension direction of the gas pipeline 330 is provided on the outside of the gas pipeline 330, and the protective shell is connected to the frame 100 to further protect the gas pipeline 330.

[0065] In other alternative embodiments, such as Figure 8 As shown, the gas pipeline 330 can also extend from the bottom of the frame 100 to the fuel cell module 200 and connect with the fuel cell module 200.

[0066] In some embodiments, such as Figure 1 As shown, the front-end hanger 10 of the modular hydrogen fuel cell with separate electric and hydrogen components in this embodiment of the invention also includes a first housing 510 and a second housing 520. The first housing 510 is disposed on the second mounting part 120 and covers the outside of the hydrogen supply module 300 to protect the hydrogen supply module 300 and prevent damage to the hydrogen supply module 300.

[0067] The second housing 520 is disposed on the first mounting part 110. The second housing 520 covers the outside of the fuel cell module 200 and the energy storage module 400 to protect the fuel cell module 200 and the energy storage module 400 from damage.

[0068] Furthermore, a first hydrogen concentration sensor is installed inside the first housing 510, configured to detect the hydrogen concentration within the first housing 510. A second hydrogen concentration sensor is installed inside the second housing 520, configured to detect the hydrogen concentration within the second housing 520. It is understood that leaks may occur at hydrogen refueling interfaces, pipe joints, pressure reducing valves, etc., under long-term vibration or seal aging. The installation of the first hydrogen concentration sensor and the second hydrogen concentration sensor in the first housing 510 and the second housing 520, respectively, ensures that any hydrogen leaks at the interfaces of the hydrogen supply module 300 or the fuel cell module 200, or other hydrogen flow structures, can be detected promptly by the first and / or second hydrogen concentration sensors, thereby improving safety performance.

[0069] Furthermore, a valve body is provided at the hydrogen outlet of the hydrogen supply module 300. When the hydrogen supply module 300 includes a hydrogen storage tank 320, the hydrogen outlet is located on the hydrogen storage tank 320. The valve body is configured to close the hydrogen outlet when the hydrogen concentration in the first housing 510 or the second housing 520 is greater than or equal to a preset threshold. That is, in the event of hydrogen leakage in the first housing 510 and / or the second housing 520, the first hydrogen concentration sensor and / or the second hydrogen concentration sensor detect the hydrogen leakage, and the valve body closes to prevent the hydrogen supply module 300 from discharging hydrogen and to prevent further hydrogen leakage.

[0070] Specifically, the first hydrogen concentration sensor, the second hydrogen concentration sensor, and the valve body are electrically connected to the controller. The opening and closing of the valve body is controlled by the controller. That is, the controller executes the computer program described above, which closes the valve body when the hydrogen concentration in the first housing 510 and / or the second housing 520 exceeds a preset threshold. The hydrogen concentration in the first housing 510 and / or the second housing 520 is detected by the first hydrogen concentration sensor and / or the second hydrogen concentration sensor, respectively, to obtain hydrogen concentration signals, which are then transmitted to the controller.

[0071] In some embodiments, such as Figure 6 and Figure 7As shown, a first vent 511 is provided on the first housing 510; a first fan 512 is provided at the first vent 511, and the first fan 512 is configured to discharge air inside the first housing 510 to the outside through the first vent 511. A second vent 521 is provided on the second housing 520; a second fan 522 is provided at the second vent 521, and the second fan 522 is configured to discharge air inside the second housing 520 to the outside through the second vent 521. Thus, by using the first fan 512 to draw air from the first housing 510 to the outside through the first vent 511, in the event of hydrogen leakage inside the first housing 510, the first fan 512 can draw hydrogen to the outside, preventing hydrogen from remaining in the first housing 510 for a long time. Similarly, the second fan 522 draws hydrogen to the outside, preventing hydrogen from remaining in the second housing 520 for a long time. Therefore, the safety performance of the front-end crane 10 of the electro-hydrogen split modular hydrogen fuel cell of this embodiment of the invention is further improved.

[0072] Furthermore, the first vent 511 is located on the side of the first housing 510 away from the second housing 520 in the width direction of the frame 100; the second vent 521 is located on the side of the second housing 520 away from the first housing 510 in the width direction of the frame 100. This allows the hydrogen in both the first housing 510 and the second housing 520 to better diffuse to the outside when hydrogen leakage occurs, preventing hydrogen accumulation.

[0073] In some embodiments, the first housing 510 is provided with a hydrogen filling port, and the second housing 520 is provided with a charging port, which corresponds to the energy storage module 400. Both the first housing 510 and the second housing 520 are provided with maintenance doors so that operators can perform maintenance through the maintenance doors.

[0074] In some embodiments, the energy storage module 400 further includes a temperature sensor (not shown) connected to the battery pack 420. The temperature sensor is configured to detect the temperature of the battery pack 420, which is beneficial for thermal management of the battery pack 420.

[0075] In some embodiments, the fuel cell module 200 further includes a cooling assembly 230 and an exhaust assembly 240. The cooling assembly 230 is connected to the fuel cell engine 220 and is configured to cool the fuel cell engine 220. The exhaust assembly 240 is connected to the exhaust port of the fuel cell engine 220 and is configured to guide the exhaust gas generated by the fuel cell engine 220 to the outside.

[0076] Specifically, the cooling assembly 230 includes a radiator and a fan. The radiator is in contact with the fuel cell engine 220, and the fan is located at the radiator to facilitate the exchange of air around the radiator with outside air. The exhaust assembly 240 includes an exhaust pipe connected to the exhaust port of the fuel cell engine 220.

[0077] In some embodiments, the electro-hydrogen split modular hydrogen fuel cell forward crane 10 is a forward crane. It should be noted that the electro-hydrogen split modular hydrogen fuel cell forward crane 10 in this embodiment can be a forward crane or other electric container handling equipment, such as a forklift.

[0078] The foregoing has provided a detailed description of the modular hydrogen fuel cell front-end hanger 10 with separate electro-hydrogen configuration provided by this invention.
