Description

Technical Field

[0001] The invention relates to a counterweighted unmanned aerial vehicle frame and the unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers.

[0003] With the rapid development and popularization of drone technology, the application scenarios are constantly expanding, and it is widely used in aerial photography, agricultural plant protection, national defense and security, etc. At the same time, the upper limit of the load that drones can currently bear is constantly increasing. As a platform for specific tools, they often face changes in load size, weight, and shape. When a drone is equipped with a gimbal camera, the rotation of the camera causes the center of gravity to shift; when a drone delivers express, the load conditions of the delivered goods vary, resulting in uneven weight distribution. The weight distribution of drones is often symmetrical, but the weight distribution of the load is always asymmetrical, causing the center of gravity of the drone to deviate from the position of the rotor lift, which in turn causes the angle of the drone to deviate, making it impossible for the drone to hover and causing turbulence.

[0004] Therefore, it is necessary to provide a counterweighted UAV frame to solve the problem of uneven weight distribution. Summary of the invention
