This design eliminates the joints and gaps between the various components of conventional designs, thereby reducing the additional space occupation due to the connectors and corners. The space waste caused by the right angle structure is avoided, so that the surrounding space can be more effectively utilized while the protective mask 1 of the vehicle-mounted hydrogen system 100 protects the gas storage bottle 2, and the overall space utilization rate is improved.

In addition, the semi-enclosed structure also facilitates installation and maintenance of the on-board hydrogen system 100. Since the in-vehicle hydrogen system 100 is semi-enclosed inside the protective mask 1, installation and fixation can be more easily performed. Meanwhile, when the gas cylinder 2 is to be checked, the protective skin side plate 12 can be unfastened, and the gas cylinder 20 can be exposed for checking, so that the whole protective mask plate 1 does not need to be detached.

Due to the bent profile of the skin side panels 12 and the skin bottom panel 11 being integrated, there is no gap or interface at the connection between them, so that potential loosening or fracture risks can be avoided. The protective mask 1 can maintain a more stable form when being subjected to external impact by seamless connection, so that the gas storage bottle 2 is effectively protected, and the stability of the vehicle-mounted hydrogen system 100 is further improved.
