Description

Technical Field The invention relates to unmanned aerial vehicle manufacturing technology field, and especially relates to an unmanned aerial vehicle. Background Art With the continuous development of unmanned aerial vehicle technology, more and more industries and individuals are used the UAV for transporting and releasing to-be-transported piece. The existing unmanned aerial vehicle (UAV) usually uses electric controlled releasing mechanism, so as to lift the to-be-transported piece during flying, and when reaching the destination, releasing the to-be-transported piece. However, through the above-mentioned releasing way, the control signal is easy to be influenced by the shielding object, in addition, on one hand, the electric control of the releasing mechanism increased the consumption of the electric quantity, on the other hand, because the mechanism is more complicated to increase the weight and manufacturing cost of the unmanned aerial vehicle, influence the endurance ability of the unmanned aerial vehicle. US 2021/ 309 357 A1 relates to a UAV, which includes a chassis, a power supply mounted to the chassis, a control system operable to receive power from the power supply, at least one rotor operable to generate lift under control of the control system, and a winch mounted to the chassis. CN 111 960 255 A relates to an automatic decoupling mechanism for hoisting equipment. US 8 985 658 B2 relates to a carabiner comprising a body having an opening and a closure movably coupled to the body, the closure being movable to an open position, and to a closed position. US 2008/ 083 100 A1 relates to a retractable hook, which is used to couple a portable article to another thing. EP 3 492 380 A1 relates to a delivered article loading apparatus, which is mounted to a lifting wire installed at a drone. US 2019/ 256 210 A1 relates to a payload retrieval apparatus. Summary of the Invention The purpose of the invention is to provide an unmanned aerial vehicle, the unmanned aerial vehicle can realize the automatic releasing of the to-be-transported piece, and the structure is simple, it is easy to realize, it can reduce the manufacturing cost of the unmanned aerial vehicle and improve the endurance ability of the unmanned aerial vehicle. For this purpose, the invention uses the following technical solution: The invention provides an unmanned aerial vehicle, having the features defined in claim 1. Further preferred embodiments are defined in the dependent claims. The beneficial effects of the invention are as follows: During transportation, the to-be-transported piece is hooked to the bottom of the mounting groove under the gravity effect of the to-be-transported piece and deforms the reset component, when the to-be-transported piece lands to the ground, the force of the to-be-transported piece on the reset component disappears, the to-be-transported piece moves towards the opening direction of the mounting groove under the reset function of the reset component and is automatically separated from the mounting groove, so as to realize automatic releasing after the to-be-transported piece lands to the ground. The UAV can realize the automatic releasing of a to-be-transported piece, and the structure is simple, it is easy to realize, it can reduce the manufacturing cost of the UAV and improve the endurance ability of the UAV.
