[0003] The current mainstream on-board hydrogen system is arranged on the rear side of the cab. Steel is welded into a hydrogen bottle frame. A horizontal multi-layer stacking scheme is adopted to assemble the hydrogen bottle in the frame to form a back-type multi-layer array structure. This installation scheme of the on-board hydrogen system occupies a certain space behind the cab, and it is not convenient to use this scheme for vehicles that are sensitive to the size of the upper body.

Each hydrogen bottle 9Y can be fixed upward by two fastening mechanisms 2 arranged at intervals.

[0048] This embodiment provides a bottom-mounted flat on-board hydrogen system 100 structural solution, which adopts modular design and can be installed as a whole as a module for multiple hydrogen bottles 9. When assembling the on-board hydrogen system 100 in this embodiment, the hydrogen bottle 9 can be fastened to the support arc groove by the fastening mechanism 2, and each support arc groove is fixed with a hydrogen bottle 9. The bottom support beam 1 can be used to support the bottom of the hydrogen bottle 9, and the hydrogen bottle 9 is arranged in a bottom-mounted flat manner to form a multi-bottle group bottom-mounted flat structure. The bottom-mounted hydrogen bottle 9 fixing method makes up for the lack of upper installation space occupied by the back of the hydrogen system.

The multiple hoisting beams 3 include side hanging beams 3a located at the ends of the bottom support beams 1 along the X direction and multiple intermediate hanging beams 3b located between the side hanging beams 3a. An intermediate support beam 4 is connected between two hoisting beams 3 opposite to each other along the Y direction.

[0050] In one embodiment, the vehicle-mounted hydrogen system 100 includes two bottom support beams 1, four side suspension beams 3a, four middle suspension beams 3b and four middle support beams 4. When assembling the vehicle-mounted hydrogen system 100 in this embodiment, first fix the four side suspension beams 3a and the four middle suspension beams 3b to the two bottom support beams 1, and the fixing method can be bolt connection, welding, etc., and then the middle support beam 4 is respectively connected to the four middle suspension beams 3b and the four side suspension beams 3a.
