Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing small unmanned aerial vehicles are weak in performing tasks with high-altitude and long-distance requirements, and to overcome the shortcomings of the "disassembly-installation" mode, which takes a long time and the process is cumbersome, and provides a Foldable small drone, its body structure can be folded and stored in a regular-shaped packing box

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 aircraft 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 present invention provides a foldable small unmanned aerial vehicle, which comprises: a wing-body fusion body; a pair of wings, respectively arranged on the left and right sides of the wing-body fusion body, each of the wings and the A first folding mechanism is arranged at the junction of the wing-body fusion body, and the first folding mechanism is configured to enable the wing to be folded downward relative to the wing-body fusion body and to lock the unfolded wing at the Expanded state; one empennage; one tail brace, one end of which is connected to the empennage, and the other end is connected to the fusion body of the wing body through a second folding mechanism, and the second folding mechanism is configured to make the tail brace relatively The wing-body fusion body is folded down and the unfolded tail brace can be locked in an unfolded state. The small unmanned aerial vehicle can be stored in a cuboid packing box after its body structure is folded, and can be automatically unfolded to the flying state by using the pneumatic device to perform flight tasks such as air delivery. At the same time, the loading and unloading time is short and the transportation is convenient.

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...
