Description

A miniature coaxial dual-propeller unmanned aerial vehicle Technical Field

[0001] This utility model relates to the field of aircraft technology, specifically to a micro coaxial dual-propeller unmanned aerial vehicle. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. A UAV consists of multiple systems, including a frame, arms, motors, antennas, image transmission systems, and flight control systems. These systems combine to form a UAV, which is suitable for applications in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, and film and television production.

[0003] As the use of drones becomes increasingly widespread, the functional requirements for drones are also increasing. Therefore, there is a need for modular drones with interchangeable image transmission and flight control structures to change drone functions. Chinese patent CN201820275864.8 states that "the positioning through hole is connected to the positioning threaded hole on the drone mounting node by screws to realize the fixed connection between the fixed base plate and the drone mounting frame." It can be seen that traditional drones usually use screws and other structures for fixing, which makes the disassembly of drone modules cumbersome and very inconvenient for maintenance and carrying.

[0004] Therefore, we propose a micro coaxial dual-propeller UAV to solve the above problems. Summary of the Invention

[0009] The propeller module is located on the top of the UAV shell and is used to drive the overall movement of the UAV. The propeller module is divided into an upper propeller module and a lower propeller module, which correspond to different positions of the propeller.

[0010] The adjustment module includes a motor, an adjustment mechanism, and a servo mechanism. The motor is coaxially connected to the propeller module, thereby controlling the rotation of the propeller module. The servo mechanism is connected to the adjustment mechanism via a pull rod, and is used to control the adjustment mechanism to adjust the operation of the motor. The servo mechanism controls the adjustment structure to adjust the operation of the motor through the received signals, thereby controlling the working mode of the propeller module and controlling the flight status of the UAV.

[0011] The control module also includes an electronic speed controller (ESC) and a flight controller (FSC), which are used to control the working state of the servo mechanism. The power module is used to supply power to the adjustment module and the control module.
