For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] The embodiment provides a hydrogen fuel truck chassis structure, which comprises a frame 100, a hydrogen supply system 200, an air inlet assembly 300, a cooling assembly 400, a battery assembly and a control assembly 600, the air inlet assembly 300 and the cooling assembly 400 are connected with the hydrogen supply system 200, the frame 100 is provided with a connecting piece 700, the hydrogen supply system 200 is detachably connected with the frame 100 through the connecting piece 700, the battery assembly and the control assembly 600 are arranged on the two sides of the frame 100, and the battery assembly and the control assembly 600 are located at the bottom of the hydrogen supply system 200.

[0028] Please refer to the drawings and Figure 2 As shown in the drawings, the air inlet assembly 300 and the cooling assembly 400 are arranged on the hydrogen supply system 200 and form a whole with the hydrogen supply system 200. The hydrogen fuel is stored in the hydrogen supply system 200, the hydrogen supply system 200 and the air inlet assembly 300 can be connected with the external fuel cell through the gas pipeline, and the cooling assembly is connected with the fuel cell through the liquid pipeline, so as to cool the fuel cell. The battery assembly is used for storing the electric quantity generated by the fuel cell, and the electric quantity is adjusted through rectification and voltage stabilization circuit to supply energy for the driving device of the vehicle, so as to ensure the stability of the vehicle. The battery assembly and the control assembly 600 are connected with the frame 100, and the battery assembly and the control assembly 600 are located at the lower end of the hydrogen supply system 200, so that the space below the hydrogen supply system 200 is fully utilized, and the arrangement of various components is more compact. The air inlet assembly 300 and the cooling assembly and other components with liquid or gas pipelines are directly connected with the hydrogen supply system 200 and form a whole with the whole hydrogen supply system 200, so as to ensure the stability of the air inlet assembly 300 and the cooling assembly, and the air inlet assembly 300 and the cooling assembly can be connected with the hydrogen supply system 200 in advance, so as to ensure the assembly efficiency. As for the battery assembly and the control assembly 600 which are relatively large in size and relatively independent in function, the battery assembly and the control assembly 600 are not connected with the hydrogen supply system 200, but are separately connected with the frame 100, so as to reduce the weight of the hydrogen supply system 200 and facilitate the subsequent hoisting and connection of the hydrogen supply system 200. At the same time, the battery assembly and the control assembly 600 are installed on the two sides of the frame 100, and the whole hydrogen supply system 200 is located above the frame 100. The battery assembly and the control assembly 600 are installed separately and will not interfere with or collide with the frame 100 or other structures, so as to ensure the safety of the equipment.

[0029] Optionally, in some possible embodiments, the connecting member 700 comprises a connecting plate 701 and a plurality of connecting bolts 702, one end of the connecting plate 701 is connected with the hydrogen supply system 200 through the connecting bolts 702, and one end of the connecting plate 701 is connected with the vehicle frame 100 through the connecting bolts 702.

[0030] Please refer to Figure 3 and Figure 4 , the hydrogen supply system 200 is connected with the vehicle frame 100 through the connecting plate 701, in addition to facilitating the disassembly and installation of the hydrogen supply system 200, the hydrogen supply system 200 can also be positioned in advance through the connecting plate 701, thereby improving the installation efficiency of the hydrogen supply system 200.

[0031] It can be understood that the weight of the entire system after integration can reach more than 3.5 tons, and many necessary systems of the hydrogen fuel vehicle such as the control assembly 600 and the battery assembly are arranged on both sides of the vehicle frame 100. When installing the hydrogen supply system 200, the entire assembly process must be carried out in an orderly manner. If the integrated hydrogen supply system 200 is assembled on the vehicle frame 100 first, it will cause obstruction to the space on the vehicle frame 100, resulting in the installation of the battery assembly and the control assembly 600 being affected and the assembly efficiency being reduced. Therefore, the battery assembly and the control assembly 600 need to be assembled in advance, and the hydrogen supply system 200 is usually installed by hoisting during assembly. During hoisting, the hydrogen supply system 200 is heavy, and the entire assembly process is very time-consuming and labor-intensive, and it is difficult to quickly position the hydrogen supply system 200 to the installation position during installation. In the present embodiment, the hydrogen supply system 200 and the vehicle frame 100 are indirectly connected through the connecting plate 701, before the battery assembly and the control assembly 600 are assembled, the connecting plate 701 can be connected with the vehicle frame 100 first to determine the installation position of the hydrogen supply system 200, and then the installation positions of the battery assembly and the controller are determined according to the position of the connecting plate 701, so as to avoid interference between the battery assembly and the controller and the hydrogen supply system 200 to be installed. Thereafter, many devices such as the battery assembly and the control assembly 600 are installed, and during installation, they are once in place, thereby avoiding installation errors and multiple disassembly and assembly, affecting the installation efficiency. Finally, the hydrogen supply system 200 after preliminary integration is hoisted, and therefore the installation position of the hydrogen supply system 200 is positioned in advance through the connecting plate 701, so that during the final assembly of the hydrogen supply system 200, the assembly precision can be guaranteed, the hydrogen supply system 200 can be quickly and accurately installed at the designated position, and collision and friction between the hydrogen supply system 200 and the battery assembly or the control assembly 600 will not occur, thereby ensuring the safety of the devices.

[0032] Optionally, in some possible embodiments, a plurality of connecting holes are arranged at intervals on the connecting plate 701, the hydrogen supply system 200 and the vehicle frame 100, and the connecting bolts 702 can be arranged in any connecting hole, so that the connecting plate 701 can be detachably connected with the hydrogen supply system 200 or the vehicle frame 100.

[0033] Please refer to Figure 4 As shown in the figure, a plurality of connecting holes are arranged on the frame 100 and the connecting plate 701 in intervals. The connecting plate 701 can be installed at any position by aligning the connecting holes on the connecting plate 701 with the connecting holes on the frame 100 at different positions and then passing the fixing bolts. It can be understood that the installation position of the connecting plate 701 needs to be adjusted according to the shape and size of the hydrogen supply system 200, so as to ensure the stability of the hydrogen supply system 200 after installation. The installation position of the connecting plate 701 can be adjusted, so as to meet the installation requirements of different models of hydrogen supply system 200 and improve the practicability.

[0034] Optionally, in some possible embodiments, the connecting holes on the connecting plate 701 include a first hole group 704 and a second hole group 705. The first hole group 704 is connected with the connecting holes on the frame 100, and the second hole group 705 is connected with the connecting holes on the hydrogen supply system 200. The hole diameter of the first hole group 704 is smaller than that of the second hole group 705.

[0035] Please refer to Figure 7 As shown in the figure, the connecting plate 701 is provided with two different diameter connecting holes, i.e., the first hole group 704 and the second hole group 705, which facilitates quick installation of the hydrogen supply system 200. It can be understood that the connecting plate 701 is installed on the frame 100 in advance, and the frame 100 is fixed during installation. Therefore, the connecting plate 701 is connected with the frame 100 by using the first hole group 704 with smaller hole diameter, so as to ensure the stability of the connecting bolt 702. When installing the hydrogen supply system 200, the hoisting method is usually used, and the hydrogen supply system 200 may vibrate slightly. At this time, the second hole group 705 with larger hole diameter is used to connect the hydrogen supply system 200, and the connecting bolt 702 can easily pass through the larger second hole group 705 during installation, which facilitates positioning and fixing of the hydrogen supply system 200.

[0036] Optionally, in some possible embodiments, the connecting plate 701 is provided with a backing plate 703, which is located at the connection between the connecting plate 701 and the hydrogen supply system 200.

[0037] Please refer to Figure 4 and Figure 5 As shown in the figure, the backing plate 703 functions as a nut, and a screw hole suitable for the fixing bolt can be formed on the backing plate 703. Since the hydrogen supply system 200 is connected with the connecting plate 701 through the larger second hole group 705, there is a gap between the second hole group 705 and the connecting bolt 702, which may vibrate and affect the connection stability. At this time, the backing plate 703 is arranged on the connecting plate 701 to assist in fixing, so as to ensure the stability of the connecting plate 701 after being connected with the hydrogen supply system 200 and improve the assembly precision.

[0038] Optionally, in some possible embodiments, the cooling assembly 400 comprises a heat dissipation device 401 arranged on the top of the hydrogen supply system 200 and an expansion water tank 402 connected in series on the liquid pipeline 403.

[0039] As shown in Figure 1 , the heat dissipation device 401 can be a forced air cooling device 401 in fuel cell related technology, which can achieve the heat dissipation effect. The heat dissipation device 401 is connected with the heat dissipation plate of the fuel cell through the liquid pipeline 403, so as to dissipate heat for the fuel cell, reduce the temperature of the fuel cell, and ensure the safety of the fuel cell. One or more expansion water tanks 402 are connected in series on the liquid pipeline 403, and the expansion water tank 402 is used to accommodate excess cooling liquid, so as to avoid damage to the liquid pipeline 403 due to expansion of the liquid, and ensure the safety of the liquid pipeline 403.

[0040] Optionally, in some possible embodiments, the heat dissipation device 401 is provided with a protective cover 800 on the side cover. Please refer to Figure 1 , the heat dissipation device 401 is arranged on the top of the hydrogen supply system 200. On the one hand, it can make full use of the installation rack structure of the hydrogen supply system 200, and does not need to be arranged separately, thereby saving the installation cost. On the other hand, it can make full use of the space on the top of the hydrogen supply system 200, improve the space utilization rate, and form a larger heat dissipation surface. The heat exchange device is not blocked by the cargo box or the cab and other components, and can fully exchange heat with the external environment, thereby improving the cooling effect. Since the heat exchange device is arranged on the top of the hydrogen supply system 200, it lacks shielding, and thus has low safety. The side cover of the heat exchange device is provided with a protective cover 800, so as to ensure the safety of the heat exchange device. In order to avoid affecting the heat exchange effect of the heat exchange device, the protective cover 800 can adopt a mesh structure, so as to ensure the flowability of the gas and improve the heat exchange effect.

[0041] Optionally, in some possible embodiments, the control assembly 600 comprises a motor controller 601, a brake air compressor 602 and a multi-in-one controller 603, which are arranged on both sides of the vehicle frame 100 respectively.

[0042] Optionally, in some possible embodiments, the battery assembly comprises a plurality of power batteries 500, which are arranged symmetrically on both sides of the vehicle frame 100.

[0043] Please refer to Figure 6As shown, the power battery 500, the motor controller 601, the brake air compressor 602 and the all-in-one controller 603 are arranged on both sides of the frame 100, on the one hand, the space on both sides of the frame 100 can be fully utilized, and the space occupancy rate is reduced. On the other hand, when the hydrogen supply system 200 is installed, the power battery 500, the motor controller 601, the brake air compressor 602 and the all-in-one controller 603 can be disassembled from both sides of the frame 100 without disassembling the hydrogen supply system 200, so that the power battery 500, the motor controller 601, the brake air compressor 602 and the all-in-one controller 603 can be conveniently maintained and replaced, and the service life of the whole device is improved.

[0044] The embodiment also provides an assembly method of the hydrogen fuel truck chassis structure, including the following steps. First, connect the heat dissipation device 401 and the air intake system with the hydrogen supply system 200, and when connecting, the mounting bracket can be arranged on the hydrogen supply system 200 to assist in fixing the air intake system, the heat dissipation device 401 and the pipeline structure. Second, install the connecting plate 701 on the frame 100 to determine the installation position of the hydrogen supply system 200. Then, arrange and install the power battery 500, the motor controller 601, the brake air compressor 602 and the all-in-one controller 603 on both sides of the frame 100, and the installation position corresponds to the position of the connecting plate 701. Finally, move the hydrogen supply system 200 installed on the heat dissipation device 401 and the air intake device to the frame 100, and connect the hydrogen supply system 200 with the frame 100 through the connecting plate 701 on the frame 100. Through the above scheme, the hydrogen fuel truck chassis is assembled, which is convenient and fast, and has better stability and safety.

[0045] The embodiment also provides a hydrogen fuel truck, which includes a cab, a driving device, a running wheel and the hydrogen fuel truck chassis structure of any one of the above, the hydrogen fuel truck chassis structure is connected with the cab, the driving device and the running wheel are arranged on the frame 100 of the hydrogen fuel truck chassis structure, the power battery 500 of the hydrogen fuel truck chassis structure is electrically connected with the driving device, and the driving device is used to drive the running wheel to rotate. The whole hydrogen fuel truck adopts the hydrogen fuel truck chassis structure provided in the above embodiment, which is easy to assemble and improves the production efficiency.

[0046] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0047] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
