[0024] In addition, in order to reduce the overall size of the frame 1, two adjacent groups of hydrogen bottle fixing belts 4 are staggered.

[0025] Furthermore, the first hydrogen bottle placement seat 2 is composed of a plurality of first support seats 2-1 with curved inner surfaces, the curved inner surface of the first support seat 2-1 faces downward and has the same curvature as the upper end surface of the hydrogen bottle; the second hydrogen bottle placement seat 3 is composed of a plurality of second support seats 3-1 with curved inner surfaces, the curved inner surface of the second support seat 3-1 faces upward and has the same curvature as the lower end surface of the hydrogen bottle. By providing the first hydrogen bottle placement seat 2 and the second hydrogen bottle placement seat 3, the hydrogen bottle can be placed stably and can also be positioned.

[0026] Furthermore, a plurality of groups of bottle body support seats 5 are vertically welded on the frame 1 on one side connected to the hydrogen bottle fixing belt 4, and each group of bottle body support seats 5 is composed of two horizontally oppositely arranged support blocks 5-1 with curved inner surfaces, and the curved inner surface of the support block 5-1 has the same curvature as the hydrogen bottle body. When the hydrogen bottle is fixed by the hydrogen bottle fixing belt 4, its side surface fits with the curved inner surface of the support block 5-1 to ensure the stability of the bottle body.

[0027] Furthermore, a supporting column 6 is arranged between two adjacent groups of hydrogen bottle fixing belts 4 and the two groups of hydrogen bottle fixing belts 4 opposite thereto.
