[0028] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0029] Reference Figures 1 to 5 As shown, a novel solid-state hydrogen storage power assembly for a two-wheeled vehicle includes a system housing 1, a solid-state hydrogen storage bottle 3, a pressure reducing valve 4, a controller 5, and a fuel cell 2 arranged in the system housing 1, wherein the system housing 1 includes two parallel first side panels 11 and second side panels 12 respectively arranged perpendicular to the first side panels 11, the second side panels 12 are detachably connected to the adjacent first side panels 11, and the fuel cell 2, the solid-state hydrogen storage bottle 3, the pressure reducing valve 4 and the controller 5 can be fixed on the first side panel 11 or the second side panel 12 respectively. During assembly, the parts can be first fixed on the corresponding side panels for debugging, and after the debugging is completed, the first side panel 11 and the second side panel 12 can be connected with bolts, and threaded holes are tapped on the first side panel 11 and the second side panel 12.

[0030] In one embodiment of the utility model, the second side plate 12 is located on the outside of the fuel cell 2, and the fuel cell 2 and the second side plate 12 are detachably connected. A plurality of air inlets 121 are provided at intervals between the corresponding positions of the second side plate 12 and the fuel cell 2, and a plurality of ventilation holes 111 are provided at intervals on the two first side plates 11, respectively, so as to maintain the air intake and ambient temperature required for the normal operation of the fuel cell 2.

[0031] In one embodiment of the utility model, a solid-state hydrogen storage bottle 3 is arranged on the outside of the fuel cell 2, a pressure reducing valve 4 is provided at the air inlet of the fuel cell 2, and the solid-state hydrogen storage bottle 3 is connected to the fuel cell 2 through the pressure reducing valve 4. Since the outlet pressure of the solid-state hydrogen storage bottle 3 is higher than the normal operation requirement of the fuel cell 2, it is necessary to arrange the pressure reducing valve 4 in front of the air inlet of the fuel cell 2. In addition, in order to improve the space utilization rate inside the assembly and realize the highly integrated design concept, the solid-state hydrogen storage powertrain for the new two-wheeled vehicle can select a bottle valve of the solid-state hydrogen storage bottle 3 with an integrated pressure reducing valve.

[0032] In one embodiment of the utility model, the controller 5 is arranged in the system housing 1, and the output end of the controller 5 is respectively connected to the fuel cell 2 and the solid-state hydrogen storage bottle 3. A hydrogen exhaust valve 6 is provided below the fuel cell 2, and the output end of the hydrogen exhaust valve 6 is arranged downward to facilitate the discharge of waste.

[0033] In one embodiment of the utility model, the upper and lower ends of the fuel cell 2 are respectively provided with a top plate 7 and a bottom plate 8 for convenient replacement of the solid hydrogen cylinder 3. The top plate 7 and the bottom plate 8 are arranged in parallel, and a hidden handle 71 is also provided on the upper end surface of the top plate 7, so as to facilitate the transfer and use of the solid hydrogen storage power assembly for the new two-wheeled vehicle.

[0034] And because the solid-state hydrogen storage bottle 3 adopts a replacement strategy, it needs to be replaced every time the hydrogen is used up, so the top plate 7 above the solid-state hydrogen storage bottle 3 is designed to be movable, and the cover plate above the fuel cell 2 is set to be immovable.

[0035] In one embodiment of the utility model, two exhaust ports 21 are provided on the lower end surface of the fuel cell 2. Since the fuel cell 2 generates water when working, the two exhaust ports 21 are both arranged vertically downward, and two fans 9 are arranged at intervals on the side of the fuel cell 2 to achieve air cooling of the fuel cell 2, thereby cooperating with the air inlet 121 to further improve the cooling efficiency.

[0036] In one embodiment of the utility model, a limiting protrusion 81 for limiting the installation position of the solid-state hydrogen bottle 3 is provided on the bottom plate 8, thereby ensuring that the relative position of the solid-state hydrogen bottle 3 and the fuel cell 2 is fixed, and the solid-state hydrogen storage powertrain for the new two-wheeled vehicle provides hydrogen to the fuel cell through the solid-state hydrogen storage bottle 3, which can effectively prevent hydrogen leakage and further improve the overall safety.

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
