Preferably, openings are provided at the rear ends of the first - layer space 11 and the second - layer space 12.

[0048] Inside the first - layer space 11, a hydrogen fuel cell assembly 2 and a hydrogen supply assembly 3 are provided. Preferably, the hydrogen fuel cell assembly 2 and the hydrogen supply assembly 3 are arranged in sequence along the front - to - rear direction. Both the hydrogen fuel cell assembly 2 and the hydrogen supply assembly 3 are slidably connected to the frame 1 in the front - to - rear direction, so that the hydrogen fuel cell assembly 2 and the hydrogen supply assembly 3 can enter and exit the first - layer space 11 through the opening at the rear end of the first - layer space 11.

[0050] Figure 3 The arrows shown in the figure indicate the directions in which the hydrogen fuel cell assembly 2, the hydrogen supply assembly 3, and the air supply assembly 4 move out of the frame 1.

At the same time, the hydrogen fuel cell assembly, the hydrogen supply assembly, and the air supply assembly are all slidably connected to the frame so that they can enter and exit the frame. Thus, when maintenance, disassembly, and assembly are required, at least part of the hydrogen fuel cell assembly, the hydrogen supply assembly, and the air supply assembly can be quickly and conveniently moved out of the frame for quick maintenance, disassembly, and assembly.

[0052] It should be noted that the reasonable layout of the hydrogen fuel cell assembly, the hydrogen supply assembly, and the air supply assembly can, on the one hand, have a high degree of compactness, enabling the hydrogen fuel cell power supply device to achieve a smaller volume. On the other hand, when at least one of the hydrogen fuel cell assembly, the hydrogen supply assembly, and the air supply assembly is moved out of the frame for maintenance, disassembly, and assembly, the mutual interference and influence between the components and the equipment within the components can be effectively avoided, facilitating quick maintenance, disassembly, and assembly.

[0053] It can be understood that the first-layer space and the second-layer space are not limited to opening at the rear end. In some other embodiments, one of the first-layer space and the second-layer space opens at the rear end, the other opens at the front end, or one opens at at least one end in the front-rear direction and the other opens at at least one end in the left-right direction.

[0054] It can be understood that the hydrogen fuel cell assembly and the hydrogen supply assembly are not limited to entering and exiting the first-layer space through the opening at the rear end of the first-layer space. In some other embodiments, openings are provided at both the front end and the rear end of the first-layer space. The hydrogen fuel cell assembly enters and exits the first-layer space through the opening at the front end of the first-layer space, and the hydrogen supply assembly enters and exits the first-layer space through the opening at the rear end of the first-layer space. The hydrogen fuel cell assembly and the hydrogen supply assembly can be set to slide synchronously or can be set to slide separately.

The cooling water supply assembly 5 is slidably connected to the frame body 1 so as to be able to enter and exit the third-layer space 13.

[0056] As Figure 1 and Figure 3 shown, a third-layer space 13 is further provided inside the frame body 1. The first-layer space 11, the second-layer space 12, and the third-layer space 13 are preferably arranged in sequence from top to bottom. In other words, the first-layer space 11 is the upper space, the second-layer space 12 is the middle space, and the third-layer space 13 is the bottom space.

[0057] The third-layer space 13 is horizontally arranged and preferably has an opening at the rear end.

[0058] A cooling water supply assembly 5 is arranged in the third-layer space 13. The cooling water supply assembly 5 is slidably connected to the frame body 1 along the front-rear direction so as to enter and exit the third-layer space 13 through the opening at the rear end of the third-layer space 13.

[0059] Thus, when it is necessary to overhaul and disassemble and assemble the cooling water supply assembly, the cooling water supply assembly can be quickly and conveniently moved out of the frame body to quickly perform overhaul and disassembly and assembly.

[0060] The cooling water supply assembly 5 is preferably connected to the hydrogen fuel cell assembly 2 through a pipeline to supply cooling water or coolant to the hydrogen fuel cell assembly 2.

[0061] It is understandable that the first - layer space, the second - layer space, and the third - layer space are not limited to being arranged in sequence along the vertical direction. In some other embodiments, the first - layer space, the second - layer space, and the third - layer space are arranged at intervals along the horizontal direction.

[0062] In some embodiments, a part of the air supply assembly 4 is arranged in the second - layer space 12 and is slidably connected to the frame 1 so as to be able to enter and exit the second - layer space 12. Another part of the air supply assembly 4 is arranged in the third - layer space 13 and is slidably connected to the frame 1 so as to be able to enter and exit the third - layer space 13.

[0063] As Figure 1 and Figure 3 shown, a part of the air supply assembly 4 is arranged in the second - layer space 12 and is slidably connected to the frame 1 in the front - to - back direction so as to be able to enter and exit the second - layer space 12 through the opening at the rear end of the second - layer space 12. Another part of the air supply assembly 4 is arranged in the third - layer space 13 and is preferably arranged in sequence with the cooling - water supply assembly 5 in the front - to - back direction. Another part of the air supply assembly 4 is also slidably connected to the frame 1 in the front - to - back direction so as to be able to enter and exit the third - layer space 13 through the opening at the rear end of the third - layer space 13, thus having a reasonable layout.

[0064] It is understandable that another part of the air supply assembly and the cooling - water supply assembly are not limited to entering and exiting the third - layer space through the opening at the rear end of the third - layer space. In some other embodiments, openings are provided at both the front end and the rear end of the third - layer space. Another part of the air supply assembly enters and exits the third - layer space through the opening at the front end of the third - layer space, and the cooling - water supply assembly enters and exits the third - layer space through the opening at the rear end of the third - layer space. Another part of the air supply assembly and the cooling - water supply assembly can be set to slide synchronously or can be set to slide separately.

[0065] In some embodiments, the hydrogen - fuel - cell power - supply device of the embodiment of the present utility model further includes a sliding assembly 6, and corresponding sliding assemblies 6 are respectively arranged in the first - layer space 11, the second - layer space 12, and the third - layer space 13. The sliding assembly 6 includes a fixing member 61 and a sliding member 62, and the fixing member 61 is slidably connected to the sliding member 62. The fixing member 61 is connected inside the frame 1.

The air supply assembly 4 is connected to the sliding member 62 in the second - layer space 12, or a part of the air supply assembly 4 is connected to the sliding member 62 in the second - layer space 12, and another part of the air supply assembly 4 is connected to the sliding member 62 in the third - layer space 13. The cooling - water supply assembly 5 is connected to the sliding member 62 in the third - layer space 13.

[0066] As Figure 1 and Figure 2As shown in the figure, the frame body 1 is provided with three sliding components 6. The three sliding components 6 are preferably arranged at intervals in the up and down direction and are respectively located in the first-layer space 11, the second-layer space 12, and the third-layer space 13. Specifically, the three sliding components 6 include a first sliding component 67, a second sliding component 68, and a third sliding component 69. The first sliding component 67 is located in the first-layer space 11, the second sliding component 68 is located in the second-layer space 12, and the third sliding component 69 is located in the third-layer space 13.

[0067] Each sliding component 6 includes a fixing member 61 and a sliding member 62. The fixing member 61 is fixedly connected to the frame body 1, and the sliding member 62 is connected to the fixing member 61 and can slide relative to the fixing member 61 in the front and back directions.

[0068] The hydrogen fuel cell assembly 2 and the hydrogen supply assembly 3 are both connected to the sliding member 62 of the first sliding component 67, so as to be slidably connected to the frame body 1 in the front and back directions through the first sliding component 67, and thus enter and exit the first-layer space 11.

[0069] A part of the air supply assembly 4 is connected to the sliding member 62 of the second sliding component 68, so as to be slidably connected to the frame body 1 in the front and back directions through the second sliding component 68, and thus enter and exit the second-layer space 12.

[0070] The cooling water supply assembly 5 and another part of the air supply assembly 4 are both connected to the sliding member 62 of the third sliding component 69, so as to be slidably connected to the frame body 1 in the front and back directions through the third sliding component 69, and thus enter and exit the third-layer space 13.

[0071] Thus, through the three sliding components 6, the hydrogen fuel cell assembly 2 and the hydrogen supply assembly 3, a part of the air supply assembly 4, the cooling water supply assembly 5, and another part of the air supply assembly 4 can respectively slide relative to the frame body 1 in the front and back directions, which is convenient for maintenance, disassembly, and assembly.

[0072] It can be understood that in some other embodiments, the air supply assembly is entirely located in the second-layer space. The air supply assembly is connected to the sliding member of the second sliding component, so as to be slidably connected to the frame body in the front and back directions through the second sliding component. The cooling water supply assembly is connected to the sliding member of the third sliding component, so as to be slidably connected to the frame body in the front and back directions through the third sliding component, and thus enter and exit the third-layer space.

[0073] In some embodiments, the fixing member 61 includes slide rails, which are connected to the frame body 1. There are at least two slide rails, and the at least two slide rails are parallel and arranged at intervals. The sliding member 62 includes a bearing plate, which is arranged on the at least two slide rails.

The hydrogen fuel cell assembly 2 and the hydrogen supply assembly 3 are arranged on the bearing plate of the first sliding assembly 67. A part of the air supply assembly 4 is arranged on the bearing plate of the second sliding assembly 68. The cooling water supply assembly 5 and the other part of the air supply assembly 4 are arranged on the bearing plate of the third sliding assembly 69.

[0078] The slide rail as the fixing member 61 not only plays a role in guiding the sliding direction but also plays a role in carrying the bearing plate and further carrying the components on the bearing plate.

[0079] It should be noted that when at least part of the components in the corresponding layer of space or at least part of the components are removed, the bearing plate can still be entirely located in the corresponding layer of space, partially located in the corresponding layer of space, or entirely located outside the corresponding layer of space.

[0080] It can be understood that the protruding part is not limited to being provided on the top surface of the sliding rail. In some other embodiments, the upper end of the sliding rail serves as the protruding part and is fitted into the recessed part at the bottom of the bearing plate.

[0081] It can be understood that the sliding member is not limited to the bearing plate. In some other embodiments, the sliding member is a slider connected to the surface of the corresponding component through a bracket. The slider is arranged on the corresponding sliding rail. Preferably, a plurality of sliders are arranged on the same sliding rail. At this time, the sliding rail is not limited to being arranged at the bottom of the corresponding layer of space and can also be arranged at the left and right ends of the corresponding layer of space.

The locking member 65 can be connected between the fixing member 61 and the sliding member 62, and at least one of the fixing member 61 and the sliding member 62 is detachably connected to the locking member 65 so that the locking member 65 locks the relative positions of the fixing member 61 and the sliding member 62.

[0084] As Figure 1 and Figure 2 shown, the sliding assembly 6 further includes a plurality of locking members 65. At least one sliding rail serving as the fixing member 61 is connected to the bearing plate serving as the sliding member 62 through the locking members 65. The locking member 65 is fixedly connected to one of the sliding rail and the bearing plate, and the other is detachably connected, or the locking member 65 is detachably connected to both the sliding rail and the bearing plate.
