A variable saucer-shaped airship UAV

Abstract

The invention belongs to the technical field of unmanned aerial vehicles and provides a variable disc-shaped airship unmanned aerial vehicle, including a disc-shaped airbag, a motor arm, an airbag bracket assembly, a compound eye camera, and a propeller. The inside of the disc-shaped airbag is supported by the airbag bracket assembly , the airbag bracket assembly includes a bearing seat, a large gear, a screw, a motor, a pinion, an upper support rod, a lower support rod, a connecting rod, a disk, and a support rod fixing seat, and a motor is fixed on the disk, and the motor drives The small gear meshes with the large gear, and then through the meshing of the thread in the center of the bearing seat and the screw rod, the bearing seat moves up and down along the screw rod, and then the disc drives the upper support rod to swing. The disc on the top of the airbag bracket and the four motors The arms are connected, and the end of each motor arm is provided with a motor seat, and the output shaft of the motor is connected with the propeller, and 6 compound eye cameras are installed symmetrically on the lower part of the disc-shaped airbag. The device of the invention has the advantages of simple structure, convenient use and portability, and can effectively improve the endurance time of the drone.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a variable saucer-shaped airship unmanned aerial vehicle. Background technique [0002] At present, unmanned aerial vehicles have been widely used in military reconnaissance and detection, missile early warning, aerial photography, security monitoring, search and rescue in disaster areas and other fields. However, the existing unmanned aerial vehicles generally have the following problems: (1) The problem of short time in the air, the existing solution is to develop new fuel cells, aluminum batteries, etc. The time is limited and the cost is high. If a foldable micro-airship is used, since the airbag itself has buoyancy in the air, it can hover without the high-speed movement of the blades. All the power is used to propel the airship forward, and the airborne time is greatly extended. (2) The problems of electromagnetic interference crashes and stron...

AI Technical Summary

Problems solved by technology

However, the existing unmanned aerial vehicles generally have the following problems: (1) the short time in the air, the existing solution is to develop new fuel cells, aluminum batteries, etc. to increase the air time of the aircraft, but the increased battery life through this method The time is limited and the cost is high. If a foldable micro-airship is used, since the airbag itself has buoyancy in the air, it can hover without the high-speed movement of the blades. All the power is used to propel the airship forward, and the time spent in the air is greatly extended.

(2) The problem of electromagnetic interference crash, strong wind disturbance crash, (3) the problem of poor portability, the existing solution is to use the method of reducing the volume of the airbag, but this will greatly reduce the payload of the airship and make the function of the airship restricted
