Ejection type unmanned aerial vehicle

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and discloses an ejection type unmanned aerial vehicle. The ejection type unmanned aerial vehicle comprises a bottom plate, supports are fixedly mounted at the four corners of the top end of the bottom plate correspondingly, an unmanned aerial vehicle body is movably arranged among the four supports, and suction blocks are fixedly mounted at the four ends of the bottom side of a support of the unmanned aerial vehicle body correspondingly; and grooves a are formed in the sides, close to the unmanned aerial vehicle body, of the four supports. Through the arranged grooves a and grooves b, when the unmanned aerial vehicle is used, the four suction blocks on the bottom side of the unmanned aerial vehicle body can be arranged on springs of the four grooves a correspondingly, an electromagnetic block is pushed through a push rod motor a, the suction blocks are sucked, so that when the push rod motor a retracts a motor shaft, the springs can be compressed, and when the springs are compressed to a certain degree, the electromagnetic block is powered off, and ejection of the unmanned aerial vehicle body is completed. Compared with the prior art, ejection in the vertical direction can be achieved, the occupied space in the prior art is effectively reduced, use is convenient, and the use effect is extremely good.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a catapult unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as unmanned aerial vehicle, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. Because of its small size, low cost, easy to use, low requirements on the combat environment, and strong battlefield survivability, it is favored by armies all over the world and is widely used in the military field. In addition, countries around the world are actively expanding the application scope of civilian drones, and the technical and economic effects of using drones in fields such as electric power, communications, meteorology, agriculture, forestry, ocean, and exploration are promising. [0003] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not b...
