A precise locking device for UAV wing positioning

Abstract

The invention discloses an accurate locking device for wing positioning of an unmanned aerial vehicle. The iron sheet is provided with a magnet sheet at the position corresponding to the iron sheet on both sides of the body. When the present invention is in use, by pulling up the handle, the hexagonal pin will break away from the positioning hole, and the hexagonal pin will move downward under the action of the spring and re-insert in the positioning hole, so as to realize the precise locking of the wing. When it is not needed, pull up the handle , close the wing, drive the rotating shaft to rotate in the fixed shaft, the iron sheet inside the wing will be adsorbed on the magnet sheet under the action of magnetic force, put down the handle, and further lock the wing to prevent the wing from opening during carrying, causing When the propeller is broken, the locking device has a simple structure, and avoids opening holes on the wings and the fuselage by adding the structure of the fixed shaft and the rotating shaft, thereby avoiding the impact on the structural strength of the fuselage.

Description

technical field The invention relates to the technical field of unmanned aerial vehicles, in particular to an accurate locking device for wing positioning of an unmanned aerial vehicle. Background technique UAV is an unmanned aircraft controlled by radio remote control equipment or onboard computer program control system. UAV has simple structure and low cost of use. It can not only complete the tasks performed by manned aircraft, but also is suitable for manned aircraft. It plays a very important role in emergency response and early warning of emergencies. At the same time, with the advancement of science, more civilian drones have been developed, and a large number of drones are used in the field of aerial photography. The aerial photography of drones has the advantages of high definition, large scale, small area, and high potentiality, and is especially suitable for obtaining Aerial images in belt-shaped areas, and drones provide convenient operation for aerial photograp...

Problems solved by technology

Most of the current UAVs use a foldable wing structure, thereby reducing the size of the UAV and making it easy to carry. Now the more commonly used folding wings use a fixed pin puller installed on the fuselage. The pins of the pin and the pin holes on the wing are used to lock the folded wing. In order to ensure the cooperation between the pin of the pin puller and the pin hole of the wing, it is necessary to assemble the pin puller and the fuselage, the wing and the fuselage, The opening of the wing pin hole is finished to ensure the precise fit between the pin and the pin hole, which is difficult to process, and opening holes on the body itself and the wing will affect the structural strength of the drone, thereby affecting The accuracy of the pin locking device will not only destroy the overall aesthetics of the drone, so we propose a precise locking device for wing positioning of the drone to solve the above problems
