The invention relates to a small-sized unmanned aerial vehicle ejector, comprising a pedaling emitter (1), an elastic pretensioner (2), an ejection pulley frame (3), a front adjustable support (4), a rear adjustable support (5), a guide rail plate (6), a front rocker (13), a rear rocker (14), slide wheels (15), a fixing board (16), a hook (17) and an elastic cord (24); a pedal (25) is arranged on the pedaling emitter (1); the front adjustable support (4) and the rear adjustable support (5) are respectively hinged onto two ends of the guide rail plate (6); multiple slide wheels (15) are symmetrically mounted on the ejection pulley frame (3) in pairs by rotary shafts. The small-sized unmanned aerial vehicle ejector is integrally made of aluminum alloy, light in weight, portable, capable of ejecting small-sized unmanned aerial vehicles with the weight smaller than 5kg, economical and safe and has no demands on take-off fields.
Description
technical field [0001] The invention relates to a catapult, in particular to a small unmanned aerial vehicle catapult. Background technique [0002] Due to the characteristics of fast maneuverability, low cost of use, and simple maintenance and use, small UAVs have been widely used at home and abroad. The take-off technology of small UAVs has always played an important role in the use. The most widely used are fixed-wing small UAVs, helicopters, multi-rotor vertical take-offs, small UAVs under 5kg, hand-throwing take-off and catapult take-off. At present, the take-off methods of small drones mainly include taxi takeoff, vertical takeoff, catapult takeoff, and hand throw takeoff; taxi takeoff has high requirements on the site; vertical takeoff requires a high-power engine to generate enough lift; hand throw takeoff requires Only professionals can do it, the cutting accuracy is low, and there is a danger of being hit by the propeller for small drones that are thrown and pushe...
