Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a dual-layer, regionally arranged structure for a fuel cell-lithium modular dual-battery system UAV. Background Technology

[0002] Drones require a power supply system, and existing power supply systems include fuel cell-lithium dual battery systems. The fuel cell-lithium dual battery system is a new type of hybrid power system that emerged based on the development of fuel cells. Compared with the traditional fuel cell-lithium battery hybrid system, the fuel cell-lithium dual battery system can achieve efficient energy utilization and increase the range.

[0003] Currently, most drones with dual-battery systems are modified from traditional lithium-ion battery drones. The modification design approach is from the outside in, mainly involving the installation of fuel cell systems and components on the existing lithium-ion battery drone, including high-pressure hydrogen cylinders, fuel cells, intake and exhaust valves, control circuit boards, and other components. The advantage is that the original lithium-ion battery drone structure can be preserved; simply adding a support structure to fix the fuel cell system components to it is sufficient. However, the disadvantages include: the original drone's system balance is affected, reducing the drone's flight attitude stability and flexibility; the added support structure and the exposed fuel cell system components leave critical components unprotected, posing safety hazards during flight; and the overall appearance is cluttered, resulting in poor integration and making replacement of corresponding equipment inconvenient.

[0011] Preferably, the drone includes a snap-fit ​​upper cover and a lower cover, and the upper cover or the lower cover is provided with a drive component for flight around its perimeter.

[0012] Compared with the prior art, this utility model has the following advantages:
