Unmanned aerial vehicle and catapult thereof

Abstract

The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle and a catapult thereof.The unmanned aerial vehicle comprises a flight mechanism, a catapulting mechanism is arranged on the flight mechanism, a folding mechanism is arranged on the catapulting mechanism, a power mechanism is installed between the folding mechanism and the catapulting mechanism, and the power mechanism drives the catapulting mechanism; a placement mechanism is rotationally arranged on the folding mechanism, and a shielding mechanism is arranged on the placement mechanism; through the arrangement of the flight mechanism, wings of the unmanned aerial vehicle can be folded and stored conveniently, the placement mechanism can transport the unmanned aerial vehicle conveniently, and the occupied space of the unmanned aerial vehicle is reduced; the folding mechanism and the flight mechanism are convenient to carry to move through the arrangement of the placement mechanism, the unfolded folding mechanism is convenient to support, and the flight track is convenient to extend through the arrangement of the folding mechanism, so that the flight mechanism obtains enough acceleration; and through the arrangement of the shielding mechanism, auxiliary parts of the flight mechanism can be shielded and protected conveniently, and the outdoor viability of the unmanned aerial vehicle and the launcher is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle and a catapult thereof. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft that is operated by radio remote control equipment and self-provided program control devices, or is operated completely or intermittently by an on-board computer. Compared to manned aircraft, drones are often better suited for missions that are too "dumb, dirty, or dangerous". The initial flight of the drone needs to be able to fly, and for this reason, the flight mission needs to be A catapult that uses acceleration. [0003] However, traditional fixed-wing UAVs take up a lot of space, and the transfer process is extremely inconvenient, and traditional ejection racks that perform ejection tasks generally need to be placed on the ground for ejection tasks. The flight preparation time, and the need to select a flat gro...

Problems solved by technology

[0003] However, traditional fixed-wing UAVs take up a lot of space, and the transfer process is extremely inconvenient, and the traditional ejection racks that perform ejection tasks generally need to be placed on the ground for ejection tasks, and the ejection parts need to be hoisted to the ground for deployment separately, extending the The flight preparation time and the need to select a flat ground to perform the launch mission strictly limit the flight conditions of the UAV; The device is easily corroded under long-term exposure to the sun or wind and rain, and cannot protect the drone and ejection parts, thereby reducing the ability to use the drone in response to emergencies, and the existing ejection There is no blocking shield on the frame, which reduces the service life of the catapult
