example 1

[0039] Example 1: Carrying out the flight mission of launching an air drop

[0040] The small drone in this state is equipped with a folding mechanism and an unfolding mechanism at the same time. When carrying out the flight mission of launching in the air, the small unmanned aerial vehicle equipped with the corresponding payload is first in such a state figure 2 The folded state shown is stored in a rectangular packing box, which can be carried by hot air balloon, airship, helicopter or large transport plane to a predetermined height and airspace for air delivery. A parachute and an automatic device for opening the hatch are installed in the rectangular packing box used to accommodate small drones. After being launched in the air, the parachute will automatically open and stabilize and descend, and then the hatch will be automatically opened to release the drone in the folded state inside.

[0041] After the UAV in the folded state slides out of the packaging box, its left ...

[0042] Example 2, rapid transition from storage state to ready-to-fly state in routine tasks

[0043] The small drone in this form can only be equipped with a folding mechanism and omit the unfolding mechanism. The left and right wings 6, 7 and the tail brace 3 are respectively connected with the wing-body fusion body 8 through a set of folding mechanisms. The wings and tailstays are folded in the storage and transportation state. When the drone arrives at the destination, take the folded drone out of the packing box, and pull the left and right wings and tailstays upward until the folding mechanism is automatically locked. The machine can reach the ready-to-fly state. After completing the flight mission, the drone can be restored to storage by simply pressing back the latch 110 of the folding mechanism, freeing it from the barbs 105, and folding the wings and tailstays down and packing them into the case status, the entire implementation process is simple and convenient.

Abstract

The invention provides a folding small-sized unmanned aerial vehicle, which comprises a wing-fuselage blended body, a pair of airfoils, an empennage and a tail boom, wherein the airfoils are respectively arranged on both sides of the wing-fuselage blended body; a connection position of each airfoil and the wing-fuselage blended body is provided with a first folding mechanism; the first folding mechanisms are used for folding the airfoils downwards relative to the wing-fuselage blended body and locking the unfolded airfoils in an unfolded state; one end of the tail boom is connected with the empennage, while the other end is connected with the wing-fuselage blended body through a second folding mechanism; and the second folding mechanism is used for folding the tail boom downwards relative to the wing-fuselage blended body and locking the unfolded tail boom in an unfolded state. After being folded, an airframe structure of the small-sized unmanned aerial vehicle can be accommodated in a cuboid packing chest; and the folding small-sized unmanned aerial vehicle can unfold to the flight condition automatically by utilizing an air-powered actuating device to execute flight tasks of air delivery and the like, and simultaneously, the small-sized unmanned aerial vehicle is short in assembly and disassembly time and convenient in transportation.

Description

technical field [0001] The invention relates to an aviation vehicle, in particular to a foldable small unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as unmanned aerial vehicle, is a powered, unmanned, reusable aircraft. In recent years, due to the rapid development of material science, microelectronics technology, and computer technology, the UAV technology has been greatly promoted. The field of drones has become a field that countries are vying for development. UAVs are generally classified by weight, among which those below 20kg are called micro or small UAVs, such as the "pointer" UAV and "Silver Fox" UAV in the United States, which are generally used to perform battlefield reconnaissance, damage Military tasks such as assessment and target guidance, as well as non-military tasks such as flight tests, aerial surveying and mapping, search and rescue as an aircraft platform. [0003] Due to the low take-off weight of the drone its...
