Technical Field

[0001] The present invention belongs to the field of micro-UAVs, and in particular relates to a method for quickly launching a group of micro-rotor UAVs. Background Art

[0002] A drone, short for unmanned aerial vehicle, is an unmanned aerial vehicle controlled by a radio remote control device and its own programmable control unit. Compared to manned aircraft, it offers advantages such as small size, low cost, and ease of use. From a technical perspective, drones can be categorized as unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned multi-rotor aircraft, and unmanned paragliders. From an application perspective, they can be divided into military and civilian applications. In the military, drones are divided into reconnaissance aircraft and target drones. In civilian applications, drones can be used in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, store inspections, disaster relief, film and television production, and creating romance.

[0030] The present invention will be further described in detail below with reference to the embodiments and the accompanying drawings, but they are not intended to limit the technical solutions of the present invention.

[0031] Example 1

[0032] The micro-rotor drone 1 of this embodiment has a cylindrical main body with four circumferentially evenly distributed wings, which are rotatably connected to the main body at the wing roots.

[0033] The storage device for a micro-rotor drone group includes a storage box 2, a constraint plate 3, a base 4 and a connecting mechanism 5. Figure 1 and 2 shown.

[0034] The storage box 2 is composed of a box cover and a box body, wherein the rear wall of the box body is fixedly connected to the bottom plate, and the left, right and front wall plates are rotatably connected to the bottom plate by hinges. When the box is folded, the left and right wall plates are respectively connected to the front and rear wall plates with buckles.

[0035] The constraint plate 3 is a flat plate structure with 5 rows and 10 columns in the middle, totaling 50 constraint holes 31. The constraint hole 31 is a circular through hole in the middle, and four circumferentially evenly distributed square grooves are opened outward from its outer circumference. The structural dimensions of the grooves match the wing shape of the micro-rotor drone 1. Figure 3 shown.

[0036] The base 4 is a square structure with a mounting groove 41 on the top. The inner diameter of the circular structure is consistent with the outer diameter of the main body of the micro-rotor drone 1. The four side panels and the bottom panel are respectively provided with mounting grooves 42, which are composed of interconnected bottom panel grooves and side wall grooves. Figure 4 shown.

[0037] The connecting structure 5 is a hinge, which includes three hinge shafts and four hinge pieces.

[0038] The storage device for a swarm of micro-rotor drones of this embodiment includes 50 bases 4, which are placed in a storage box 2. Among them, in a row of bases 4 that are in contact with the rear wall of the storage box 2, the base 4 near the middle position is fixedly connected to the rear wall of the storage box 2; two adjacent bases 4 are connected by a connecting mechanism 5. When connected, the hinges at both ends of the connecting mechanism 5 are respectively fixed in the bottom plate grooves of two adjacent mounting grooves 42.

[0039] When using the storage device of this embodiment to store a group of micro-rotor drones, the storage box 2 is retracted, with adjacent bases 4 in close contact. The two hinges in the middle of the connecting structure 5 are bent upward and stored in the sidewall grooves of two adjacent mounting slots 42. Each base 4 has a micro-rotor drone 1 placed in its placement slot 41, with its wings rotated downward and stowed. The restraining plate 3 is located within the storage box 2, above the base 4. Its restraining holes 31 fit over the micro-rotor drone 1 with its wings retracted, preventing the wings from unfolding within the storage box 2.

[0040] When flying a swarm of micro-rotor drones, first, open the lid of the storage box 2, loosen the connecting buckles of the side panels of the box, and flatten and unfold the front, left and right side panels; then remove the constraint plate 3 from the top, apply outward pulling force to the base 4 from the front, left and right directions, and the hinges of the connecting mechanism 5 gradually flatten as the base 4 moves, and the wings of the micro-rotor drone 1 also gradually flatten. Under the control of the remote control, the wings rotate, and the micro-rotor drone 1 flies out of the storage box 2.

[0041] The micro-rotor UAV group stored by the storage device of this embodiment can realize the takeoff of any number of micro-rotor UAVs under the control of the remote controller as needed.

[0042] Example 2

[0043] The difference from Example 1 is that:

[0044] The storage device for a micro-rotor drone swarm of this embodiment includes a storage box 2 , a base 4 and a connecting mechanism 5 .

[0045] The base 4 has a placement slot 41 with four circumferentially evenly distributed square receiving slots 43. Figure 5 shown.

[0046] When using the storage device of this embodiment to store a group of micro-rotor drones, first fold up the wings of the micro-rotor drone 1 and insert it into the placement groove 41 of the base 4. The wings fall into the storage groove 43 and are constrained by it.

[0047] When using the storage device of this embodiment to release a group of micro-rotor drones, first, according to the number of drones to be released, the corresponding micro-rotor drone 1 is pulled upward from the placement slot 41 by a certain distance until the wings are free from the constraints of the storage slot 43 and are in an unfolded state; then the micro-rotor drone 1 is released to maintain its vertical state in the storage box 2; finally, under the control of the remote control, the wings rotate and the micro-rotor drone 1 flies out of the storage box 2.

[0048] Example 3

[0049] The difference from Example 2 is that:

[0050] The base 4 of this embodiment is composed of four identical structural units, and a connecting device 44 is provided at the connection between two adjacent structural units. The connecting device 44 is a hinge. Figure 6 shown.

[0051] When a group of micro-rotor drones is launched using the storage device of this embodiment, when an outward pulling force is applied to the base 4, the four structural units constituting the base 4 move away from each other, driving the hinge to extend, and the wings of the micro-rotor drone 1 break free from the constraints of the storage slot 43 and gradually flatten.

[0052] The storage device of this embodiment eliminates the need to manually release the wing restraints when launching the micro-rotor drone 1, thereby further shortening the launch time and improving the launch efficiency. In addition, as the structural units of the base 4 move away from each other, the friction force during the launch of the micro-rotor drone can be reduced.

[0053] Example 4

[0054] The difference from Example 3 is that:

[0055] The connecting device 44 is a spring.

[0056] In the storage device of this embodiment, after the wings of the micro-rotor drone 1 are flattened and the tension is removed, the four structural units of the base 4 are rebounded by the springs and restored to the assembled state, thereby shortening the reassembly time of the storage device.

[0057] Example 5

[0058] The difference from Example 1 is that:

[0059] The storage device for a micro-rotor drone swarm of this embodiment includes a storage box 2 , a base 4 , a connecting mechanism 5 , a stopper 6 and a traction rope 7 .

[0060] The storage box 2, the box cover and the rear wall plate and the four wall plates and the bottom plate are all rotatably connected by hinges. A sealing strip is set at the wall plate joint to ensure the sealing of the storage box 2.

[0061] The base 4 has a placement slot 41 with four circumferentially evenly distributed through receiving slots 43, and a vertical mounting slot 42 in the middle of the side wall. Figure 6 shown.

[0062] The connecting mechanism 5 is a hinge structure, which is composed of two sets of symmetrically arranged chains. Each set of chains is connected by two square bars at the ends in a rotatable manner, and the corresponding square bars of the two sets of chains are connected in a rotatable manner in the middle position. Figure 7 shown.

[0063] The stopper 6 is a square block with a vertical groove on its outer wall, and its structural dimensions match the vertical mounting groove 42.

[0064] The storage device for a micro-rotor drone swarm of this embodiment includes 25 bases 4 placed in a storage box 2, wherein the base 4 at the center is fixedly connected to the bottom plate of the storage box 2. A block 6 is placed in the through storage groove 43 of the base 4, and the two are rotatably connected, wherein the vertical groove of the block 6 is connected to the vertical mounting groove 42. Four traction ropes 7 are respectively located between the four wall panels of the storage box 2 and the base 4; the traction ropes 7 are connected to all the block 6 located on the outermost side by means of elastic pull ropes, such as Figure 8 shown.

[0065] When the storage box 2 is in the retracted state, adjacent bases 4 are in close contact; the two chains of the connecting structure 5 are in a tightened state, stored in the vertical mounting slots 42 and vertical slots of the adjacent bases 4 and the stopper 6. Each micro-rotor drone 1 placed in the base 4 has its wings restrained by the stopper 6 and in a retracted downward position.

[0066] To launch a swarm of micro-rotor drones, first open the lid of storage box 2, loosen the latches connecting the side panels, and flatten the front, left, and right side panels. Then, pull base 4 outward from the front, left, and right. The hinges of connecting mechanism 5 gradually flatten as base 4 moves. Driven by connecting mechanism 5, stoppers 6 rotate outward. Unconstrained by the constraints, the wings of micro-rotor drones 1 automatically rotate upward, gradually flattening. Under the control of the remote control, the wings rotate, and micro-rotor drones 1 fly out of storage box 2.
