It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] like Figures 1 to 3As shown, this embodiment provides a chassis layout structure, which includes a front frame module 1, a fairing 9, an integrated frame 3, a power battery 4, an electric drive axle system 5, a frame longitudinal beam 7, a power battery cooling module 11, a brake air compressor 12, a multi-function controller 13, an air tank 14, and an electric power steering pump 15. Along the vehicle's driving direction, the front frame module 1, fairing 9, power battery 4, and electric drive axle system 5 are arranged sequentially, and both the power battery 4 and the electric drive axle system 5 are connected to the frame longitudinal beam 7. The integrated frame 3 is located downstream of the fairing 9 along the vehicle's driving direction, and the projection of the integrated frame 3 perpendicular to the vehicle's driving direction is located inside the projection of the fairing 9 perpendicular to the vehicle's driving direction. The power battery cooling module 11, brake air compressor 12, multi-function controller 13, air tank 14, and electric power steering pump 15 are all located inside the integrated frame 3.
[0032] Specifically, in this embodiment, as Figure 1 As shown, the integrated frame 3 is arranged on the rear side of the fairing 9 along the vehicle's driving direction, and the width of the integrated frame 3 is no greater than the width of the fairing 9, and the height of the integrated frame 3 is no greater than the height of the fairing 9. This ensures that the arrangement of the integrated frame 3 does not affect the vehicle's storage space and ensures the vehicle's aerodynamic performance. The power battery cooling module 11, brake air compressor 12, multi-function controller 13, air tank 14, and electric power steering pump 15 are all located inside the integrated frame 3. This helps to reduce the length of the connecting harnesses and connecting pipes between components, thereby greatly saving layout space. At the same time, it improves the convenience of maintenance and assembly, reduces maintenance costs, and helps to improve the vehicle's stability and braking performance.
[0033] Optionally, in this embodiment, the radiator and fan arranged at the front of the vehicle are collectively referred to as the front-end module 1 of the vehicle frame, and since it is prior art, it will not be described in detail here.
[0034] Optionally, in this embodiment, the front-end module 1 of the frame, the fairing 9, the integrated frame 3, the power battery 4, and the electric drive axle system 5 are arranged sequentially along the vehicle's driving direction. This arrangement is existing technology and will not be described in detail here.
[0035] Furthermore, at least a portion of the integrated frame 3 is located inside the fairing 9 along the height direction of the vehicle. Specifically, in this embodiment, the partial location of the integrated frame 3 inside the fairing 9 allows the integrated frame 3 to occupy part of the space at the bottom of the fairing 9, thereby increasing the space utilization rate of the vehicle.
[0036] Furthermore, such as Figure 1As shown, the chassis layout structure also includes a hydrogen fuel cell engine 2 and a hydrogen fuel cell engine cooling module. The hydrogen fuel cell engine 2 is located on the rear side of the front frame module 1 along the vehicle's driving direction, and the hydrogen fuel cell engine cooling module is located between the hydrogen fuel cell engine 2 and the front frame module 1. Specifically, in this embodiment, the hydrogen fuel cell engine 2 is located on the rear side of the front frame module 1 along the vehicle's driving direction. The front frame module 1 can provide a certain degree of protection for the hydrogen fuel cell engine 2, thereby improving safety during use. Furthermore, the location of the hydrogen fuel cell engine cooling module between the hydrogen fuel cell engine 2 and the front frame module 1 facilitates the connection of cooling water pipes, improves space utilization, and allows the air blown in through the front frame module 1 to efficiently remove heat, thereby improving the heat dissipation effect and ensuring the normal operating temperature of the hydrogen fuel cell engine 2.
[0037] Furthermore, such as Figure 1 As shown, the hydrogen fuel cell of the hydrogen fuel cell engine 2 is arranged between the cab and the longitudinal beam 7 of the frame, and the hydrogen fuel cell engine 2 is suspended at the bottom of the frame. Specifically, in this embodiment, the hydrogen fuel cell is connected to the frame by suspension, which improves the vibration resistance of the hydrogen fuel cell. The arrangement of the hydrogen fuel cell between the cab and the longitudinal beam 7 of the frame provides a certain degree of protection for it, improving safety during use. In this embodiment, the distance between the bottom of the hydrogen fuel cell and the lower wing surface of the frame is less than 400mm, so as to ensure that the fuel cell has sufficient distance from the ground when the vehicle bounces during driving, thereby avoiding collisions to the hydrogen fuel cell and further improving its safety.
[0038] Furthermore, such as Figure 1 As shown, the electric drive axle system 5 is located on the rear axle. The electric drive axle system 5 includes an electric drive axle, an electric drive axle control system, and an electric drive axle motor. The electric drive axle motor and the electric drive axle control system are arranged in front of the electric drive axle along the vehicle's travel direction, and both are connected to the electric drive axle. Specifically, in this embodiment, the electric drive axle system 5 is located on the rear axle and connected to the vehicle frame via the rear suspension system, thereby improving the installation stability of the electric drive axle system 5. The electric drive axle system 5 includes an electric drive axle, an electric drive axle control system, and an electric drive axle motor. The electric drive axle motor and control system are connected to the electric drive axle in front of it, which can improve transmission efficiency and save space in the traditional diesel vehicle drive shaft for accommodating the power battery 4.
[0039] Furthermore, such as Figures 1 to 3As shown, the power battery 4 is located between the hydrogen fuel cell engine 2 and the electric drive axle system 5, and the power battery heat dissipation module 11 is located on the upper inner side of the integrated frame 3. Specifically, in this embodiment, the power battery 4 is arranged at the center of the longitudinal beam 7 of the vehicle frame. This arrangement can improve the space utilization of the chassis, making the layout of each component compact and reasonable, and improving the rationality of the layout. At the same time, the power battery heat dissipation module 11 is located on the upper inner side of the integrated frame 3. The integrated frame 3 can provide support for the power battery heat dissipation module 11, and the high position of the power battery heat dissipation module 11 is conducive to air circulation, which can effectively improve heat dissipation performance, ensure the operating temperature of the power battery 4, and improve the thermal stability of the power battery 4.
[0040] Preferably, in this embodiment, the power battery 4 is connected to the vehicle frame via a bracket to improve its installation stability.
[0041] Preferably, in this embodiment, the charging port of the power battery 4 is located on the left side of the vehicle along the driving direction and in front of the hydrogen storage system 8.
[0042] Furthermore, such as Figures 1 to 3 As shown, two power battery cooling modules 11 are provided, and the two power battery cooling modules 11 are arranged at intervals. Specifically, in this embodiment, the two power battery cooling modules 11 are arranged at intervals along the width direction of the vehicle on the upper inner side of the integrated frame 3, thereby further improving the heat dissipation efficiency.
[0043] Furthermore, such as Figures 1 to 3 As shown, both the multi-function controller 13 and the air tank 14 are located on the lower inner side of the integrated frame 3, and are spaced apart. Specifically, in this embodiment, both the multi-function controller 13 and the air tank 14 are located on the lower inner side of the integrated frame 3. The integrated frame 3 ensures the installation stability of the multi-function controller and the air tank 14. The multi-function controller 13 is located on the left side of the integrated frame 3 along the vehicle's driving direction, which facilitates connection with internal components of the vehicle frame, simplifies wiring harness layout, reduces wiring harness length, and helps reduce energy loss. The air tank 14 is located on the right side of the integrated frame 3 along the vehicle's driving direction and is spaced apart from the multi-function controller 13. This prevents the multi-function controller 13 and the air tank 14 from colliding with each other. In this embodiment, the base plates of both the multi-function controller 13 and the integrated frame 3 are connected to a side plate on one side, which improves the installation stability of the multi-function controller 13. At the same time, the base plates of both the air tank 14 and the integrated frame 3 are connected to a side plate on the other side, which improves the installation stability of the air tank 14 and ensures safety during use.
[0044] Furthermore, such as Figures 1 to 3As shown, the brake air compressor 12 is disposed between one of the power battery cooling modules 11 and the multi-function controller 13, and the electric power steering pump 15 is disposed between another power battery cooling module 11 and the air reservoir 14. Specifically, in this embodiment, this arrangement ensures that the components are evenly distributed, thereby avoiding mutual collisions between components, improving safety during use, and the positional relationship between the components is reasonably arranged, reducing unnecessary space waste.
[0045] Furthermore, such as Figure 1 As shown, the chassis layout also includes a hydrogen storage system 8, which is arranged on both sides of the frame longitudinal beam 7 and located between the front suspension and the rear axle mudguard 6. Specifically, in this embodiment, the hydrogen storage system 8 is arranged in the area between the front axle and the rear axle of the vehicle. The hydrogen storage system 8 includes a receiving compartment fixedly installed on the frame longitudinal beam 7 and several hydrogen storage tanks symmetrically distributed within the receiving compartment. The receiving compartment covers both sides and the bottom of the frame longitudinal beam 7. The hydrogen refueling port is located on the front left side of the receiving compartment. The upper edge of the hydrogen storage system 8 does not exceed the height of the frame, and the width of the receiving compartment does not exceed the maximum limit stipulated by regulations.
[0046] Furthermore, such as Figure 1 As shown, the chassis layout also includes a low-voltage battery 10, which is located on the left side of the frame longitudinal beam 7 and between the front suspension and the hydrogen storage system 8. Specifically, in this embodiment, this arrangement makes the maintenance and replacement of the low-voltage battery 10 more convenient and allows for easy charging.
[0047] The chassis layout structure provided in this embodiment is applicable to the new energy vehicles equipped with hydrogen fuel cells, as well as other types of fuel cell vehicles and pure electric vehicles. It can integrate the new energy electric drive-related components of the vehicle, thereby improving space utilization and the convenience of maintenance and assembly. No specific limitations are made here.
[0048] Furthermore, the hydrogen fuel cell engine 2, integrated frame 3, power battery 4, electric drive axle system 5, rear axle mudguard 6, frame longitudinal beam 7, hydrogen storage system 8, fairing 9, low-voltage battery 10, power battery heat dissipation module 11, brake air compressor 12, multi-function controller 13, air tank 14, and electric power steering pump 15 in this embodiment are all existing technologies and will not be described in detail here.
