Problems solved by technology

[0002] In the field of ejection of small UAVs weighing more than 50 kg, there is no electromagnetic catapult suitable for such UAVs in China. According to reports, only the United States and Israel have similar UAV boosters. Domestically produced rubber band catapults can only eject Boost drones below 50 kg, and drones weighing more than 50 kg can only be boosted by solid explosive rockets, which is very dangerous and very difficult to carry and transport

Abstract

The invention relates to a mechanical double-joint and spring structured actuator of a catapult for an unmanned aerial vehicle. The actuator comprises mainly a fixed box, a semicircular actuating fastener, a spring, a semicircular pressing structure with a handle and the like; the spring is mounted in the center of the semicircular actuating fastener in the fixed box; the semicircular pressing structure is in contact with the semicircular actuating fastener; after the semicircular pressing structure is moved for a travel over one third, the spring pushes the semicircular actuating fastener to quickly slide to the other side, thereby allowing actuation.

Description

Technical field [0001] The invention relates to an unmanned aerial vehicle catapult activation device with a mechanical double joint plus spring structure, in particular to an activation buckle with two semicircular joints and a spring. It belongs to the technical field of unmanned aerial vehicle catapults. Background technique [0002] In the field of ejection of small UAVs weighing more than 50 kg, there is no electromagnetic catapult suitable for such UAVs in China. According to reports, only the United States and Israel have similar UAV boosters. Domestically produced rubber band catapults can only eject UAVs under 50 kg can be boosted, and UAVs weighing more than 50 kg can only be boosted by solid explosive rockets, which is very dangerous and very difficult to carry and transport. Contents of the invention [0003] The UAV catapult excitation device with mechanical double joint and spring structure, the main structure includes a fixed box, a semicircular activation ...
