Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a mother - son unmanned aerial vehicle for aerial delivery. Background Art

[0002] At present, in the field of unmanned aerial vehicles, unmanned aerial vehicles generally operate alone, that is, a single unmanned aerial vehicle performs tasks. Currently, reconnaissance and single - use impact unmanned aerial vehicles on the market generally perform tasks separately. That is, first, the reconnaissance unmanned aerial vehicle completes the reconnaissance task, and then the impact unmanned aerial vehicle performs the impact task. However, the current reconnaissance and impact unmanned aerial vehicles generally use disposable ones. The disposable impact unmanned aerial vehicle has a short range and cannot achieve long - distance flight. In order to make up for the long - distance flight endurance problem, only the cost of the unmanned aerial vehicle can be increased to increase the flight range. However, as a disposable impact unmanned aerial vehicle, the cost is too high. Therefore, the current solution is to conduct reconnaissance and impact by dropping the son - unmanned aerial vehicle. For example, the publicly disclosed patent 202211274053.3 provides a drop - type early warning unmanned aerial vehicle, which conducts reconnaissance work by the form of the mother - unmanned aerial vehicle dropping the son - unmanned aerial vehicle. However, this structure cannot complete the impact attack action, and the carried son - unmanned aerial vehicle only has the reconnaissance function, with single function and overlapping function with the mother - unmanned aerial vehicle. At the same time, the son - unmanned aerial vehicle needs to be recovered. In order for the mother - unmanned aerial vehicle to carry the son - unmanned aerial vehicle back to the base, the cost also needs to be increased. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a mother - son unmanned aerial vehicle for aerial delivery. By using an unmanned aerial vehicle with long - distance flight performance (unmanned aerial vehicle mother - machine) to carry an impact - type unmanned aerial vehicle with a short - range flight (unmanned aerial vehicle son - machine), first, long - distance flight and reconnaissance are carried out. When reaching the target area, the unmanned aerial vehicle mother - machine drops the unmanned aerial vehicle son - machine through the dropping mechanism, and then the unmanned aerial vehicle mother - machine returns to the base for recovery without carrying the son - machine back. The son - machine is for single - use, which is convenient for cost control.

[0004] The utility model provides a mother - son unmanned aerial vehicle for aerial delivery, including an unmanned aerial vehicle mother - machine, a suspension dropping mechanism, and an unmanned aerial vehicle son - machine. The suspension dropping mechanism is arranged at the lower end of the wing of the unmanned aerial vehicle mother - machine. The unmanned aerial vehicle son - machine is installed on the suspension dropping mechanism and is installed at the lower end of the wing of the unmanned aerial vehicle mother - machine through the suspension dropping mechanism. The suspension dropping mechanism includes a suspension clip and a dropping mechanism. The unmanned aerial vehicle son - machine is clamped by the suspension clip, and when dropping is required, the dropping mechanism controls the suspension clip to open, and the unmanned aerial vehicle son - machine is dropped under the action of gravity and inertia.

[0005] Further improvement lies in that: the unmanned aerial vehicle son - machine is a foldable and automatically deployable unmanned aerial vehicle. When the suspension clip clamps the unmanned aerial vehicle son - machine, the main wing, auxiliary wing, and tail wing of the unmanned aerial vehicle son - machine are all folded in the body groove of the unmanned aerial vehicle son - machine through the folding mechanism.

[0006] A further improvement lies in that auxiliary stabilizing wings are arranged in front of and behind the main wing of the mother drone. The auxiliary stabilizing wings reduce the shaking caused by the change in weight before and after the mother drone releases the child drone.

[0007] A further improvement lies in that a stabilizing airfoil is arranged at the end of the fuselage of the mother drone. The stabilizing airfoil is triangular in shape and plays a role in stabilizing the fuselage.

[0008] A further improvement lies in that arc-shaped support feet are arranged at the lower end of the fuselage of the mother drone, and the mother drone is supported by the support feet.

[0009] A further improvement lies in that the folding mechanism of the child drone is wirelessly connected to the release mechanism by signal. One second after the release mechanism completes the release action, the folding mechanism of the child drone removes the external force to open the wings and tail of the child drone.

[0010] A further improvement lies in that an angled tail hook is arranged at the end of the main wing of the mother drone to enhance the stability of the main wing.

[0011] The beneficial effects of the present utility model are as follows: Through the cooperation of the mother drone and the child drone, the mother drone with long-distance flight performance carries the impact-type child drone with a short-distance flight range. First, it conducts long-distance flight and reconnaissance. When reaching the target area, the mother drone releases the child drone through the release mechanism, and then the mother drone returns to the base for recovery. It provides a feasible solution for the market demand for the application of reconnaissance and disposable impact-type drones, can realize the application scope of long-distance and large-scale reconnaissance and disposable impact-type drones, and at the same time reduces the application cost of such drones.

[0019] This air-dropping mother-and-son drone system can enable a mother drone to carry 4 drone sub-vehicles at the same time, and can achieve long-distance reconnaissance. After reaching the designated target area, the drone sub-vehicles are launched through the launching mechanism. The drone sub-vehicles can achieve target reconnaissance and one-time impact within the target area. After launching the drone sub-vehicles, the mother drone can return to the base. This launching mother-and-son drone system solves the tasks of long-distance reconnaissance, reconnaissance within the target area, and one-time impact on the target.
