Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a rotary wing unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles, referred to as "drones", are unmanned aerial vehicles that are controlled by radio remote control equipment and self-contained program control devices. From a technical point of view, they can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, unmanned paragliders, etc. Among them, rotary-wing drones are the most commonly used in cargo drones.

[0003] According to the publication number CN214165301U, a rotary wing UAV is first opened to open the door panel of the cargo box, and the items to be transported are placed on the carrier. Then, the electric push rod is operated to drive the guide slide plate to rise. Under the common guidance of the transverse guide hole and the oblique guide hole, the two connecting blocks and the L-shaped extrusion plate are driven to slide in the direction close to each other, so that the two L-shaped extrusion plates clamp and fix the transported items on the carrier to avoid the transported items from colliding with the inner wall of the cargo box during the freight process and causing damage. Then, the door panel is closed and the UAV body is started for transportation. When landing, the first spring plays the role of the first step of shock absorption. At the same time, the cargo box descends. Under the rotation connection of the two transfer rods, the two sliding plates are driven to slide in the direction close to each other. The second spring is squeezed, thereby playing a further shock absorption effect. The combination of the two shock absorption effects makes the practical device have a good shock absorption effect on the transported items when the UAV lands, avoiding damage due to vibration, thereby improving the practicality of the device.

[0004] The items can be fixed by structures such as the above-mentioned L-shaped extrusion plate, but the cargo box is prone to shaking when the drone lands. After the items are fixed by the L-shaped extrusion plate, the items cannot move between the L-shaped extrusion plate, which can easily cause the items to be squeezed between the L-shaped extrusion plate and cause damage to the items.
