Problems solved by technology

[0005] Existing fuel cell UAVs use a separate external hydrogen storage tank to supply hydrogen to the fuel cell, which makes the structure of the UAV more complicated, the space utilization rate is low, and the volume and weight occupied by the hydrogen storage tank are too large. Relatively large, which is contrary to the lightweight design of the fuel cell and the design direction with a high degree of integration

Abstract

The invention is applicable to the technical field of unmanned aerial vehicles and portable power equipment, and discloses an unmanned aerial vehicle and portable power equipment. The drone includes a drone body, the drone body includes a hydrogen storage tank as an arm and a power component connected to the hydrogen storage tank, the drone also includes a fuel cell connected to the drone body, and the power component is electrically connected in fuel cells. The portable power device includes a device body, the device body includes a hydrogen storage tank as a support and a power assembly connected to the hydrogen storage tank, the portable power device also includes a fuel cell connected to the device body, and the power assembly is electrically connected to the fuel cell. In the UAV and portable power equipment provided by the present invention, the UAV uses the hydrogen storage tank as a part of the fuselage as the arm, and is no longer externally installed separately, which improves the space utilization rate and simplifies the structure of the UAV. The integration is high, and the weight of the fuselage is realized, which is beneficial to improve the endurance time of the UAV.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles and portable power equipment, and in particular relates to an unmanned aerial vehicle and portable power equipment. Background technique [0002] Electric multi-rotor drones have been widely used in military and civilian fields due to their advantages of simple operation, high mobility, and low cost, and have gradually become the mainstream type of micro-miniature drones. In recent years, they have been widely used in aerial photography drones , but the low mileage has become one of the key factors restricting its application and development. [0003] Fuel cell UAV is a new type of electric UAV with fuel cell as the main power source. It is the most potential type of UAV under the background of long-endurance application requirements of medium and low-altitude electric UAVs. It has become a research hotspot at home and abroad. . Fuel cell drones use hydrogen as fuel to directly ...
