Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen-powered electric bicycles, in particular to a power structure of a hydrogen-powered electric bicycle. Background Art

[0002] As a new type of green transportation tool, the promotion and application of hydrogen electric bicycles are accelerating. The advantages of this new type of transportation tool are its long driving range, fast energy replenishment and relatively low comprehensive energy cost. These characteristics make it an important choice for future urban travel, tourism and other fields. The power structure is one of the most important components of hydrogen electric bicycles.

[0003] Since the solid-state hydrogen storage bottle inside the power structure of a hydrogen-powered electric bicycle is often set obliquely upward, the bottleneck is prone to freezing when releasing hydrogen, which affects the use effect and is difficult to promote. It can no longer meet people's needs. For this reason, we propose a new type of hydrogen-powered electric bicycle power structure to solve the above-mentioned defects and provide better use effects.

[0009] Furthermore, an inner shell and an outer shell are respectively provided on the inner and outer sides of the bicycle crossbar assembly, and the materials of the inner shell and the outer shell are both aluminum alloy. By setting the bicycle crossbar assembly as a composite structure composed of the inner shell and the outer shell made of aluminum alloy, the structural strength of the bicycle crossbar assembly is improved.

[0010] Furthermore, the inner shell is provided with an assembly cavity for a hydrogen storage bottle that matches the solid-state hydrogen storage bottle, so that it is convenient to realize the rapid positioning and assembly of the solid-state hydrogen storage bottle inside the inner shell.

[0011] Furthermore, an arc-shaped buffer protection layer matching the solid-state hydrogen storage bottle is provided on the hydrogen storage bottle assembly cavity, and the arc-shaped buffer protection layer is made of silicone rubber, so that it is convenient to use the arc-shaped buffer protection layer made of silicone rubber to provide buffering and anti-collision protection for the solid-state hydrogen storage bottle installed inside the inner shell.

[0012] Furthermore, a connecting pipe is provided between the fan and the fuel cell.

[0013] Furthermore, the fuel cell and the stack controller are electrically connected via a wire.

[0014] Furthermore, the hydrogen outlet is arranged obliquely downward, and the bicycle crossbar assembly, the bicycle reserved groove and the bicycle head pipe form a disassembly and installation structure through screws, so that the device achieves the advantages of a split type and is easy to assemble and maintain.

[0015] Compared with the prior art, the beneficial effects of the utility model are:
