Multi-rotor unmanned aerial vehicle

Abstract

The invention discloses a multi-rotor unmanned aerial vehicle, which comprises a center plate, a foot stand, jib arms, motor bases, motors, screw propellers and an antenna. The foot stand is arranged under the center plate; the antenna is arranged above the center plate; one ends of the jib arms are connected with the center plate through joint parts; the other ends of the jib arms are connected with the motor bases; the motors are arranged on the motor bases; the screw propellers are arranged on the motors; a suspension frame is also arranged on the bottom part of the center plate; two parallel mounting rods are arranged on the suspension frame; and a camera mechanism, a nacelle mechanism and a loudspeaker are sequentially mounted on the mounting rods. The multi-rotor unmanned aerial vehicle provided by the invention applies a low-altitude flight platform of a small unmanned aerial vehicle, and is simple in structure, convenient to operate and control, and excellent in using effect, and the application field of the small unmanned aerial vehicle is widened.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a multi-purpose multi-rotor drone. Background technique [0002] With the rapid development of high-tech technologies such as automatic control technology and information technology, great progress has also taken place in UAV technology. In particular, low-altitude small and micro UAVs have the remarkable characteristics of short development cycle, low cost, low risk of use, and easy operation and learning. field.

AI Technical Summary

Problems solved by technology

For example, at present, in important occasions such as celebrations, commercial promotions, and group activities, the operation methods for creating scenes such as flower petals, snowflakes, and promotional materials are still done manually or mechanically on the ground, which has poor sense of reality and requires many hands. , and other shortcomings

In the emergency response to disasters, for the trapped people who need help, due to the limitations of transportation devices, on-site disaster environment, traffic conditions and other factors, it is impossible to achieve the fastest response

For disasters such as high-rise building fires, earthquakes, and rock landslides, the traffic conditions are inconvenient or severely damaged, and the ground is difficult to pass even on foot, hindering the transportation and delivery of relief materials

For the existing air delivery method of relief supplies, on the one hand, it is inconvenient to dispatch the aircraft and consumes a lot of money. For throwing, it is difficult to accurately locate the throwing point, and there is a large waste of throwing materials, and the degree of utilization is low; for low-altitude helicopters, the operation is difficult and the risk is greater
