[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) landing, and in particular to an airbag for UAV landing at sea. Background Art

[0002] With the development of science and technology, drones are increasingly used in the fields of ocean monitoring, maritime search and rescue, resource exploration, etc. In these missions, drones may need to land at sea to perform specific tasks or respond to emergencies. However, most of the existing drones land directly on the ground or are recovered by skyhook or parachute, and the sea environment is complex. Traditional drone landing methods face many challenges: 1. Hard landing risk. A hard landing directly on the sea surface may cause serious damage to the drone, affecting its service life and mission execution capabilities; 2. Stability issues. The fluctuation of the sea surface will make it difficult for the drone to remain stable during the landing process, increasing the difficulty and risk of landing. Therefore, existing drones have the problem of being unable to land on the sea surface, unable to ensure the integrity and reusability of the drone after landing, and unable to float on the sea surface. Summary of the invention

[0018] The technical solution provided by the embodiments of the present invention is described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 , Figure 2 As shown, the drone sea landing airbag of this embodiment includes an airbag 9 and an airbag inflation mechanism for filling gas into the airbag 9. Specifically, Figure 2 As shown, the airbag inflation mechanism includes an air tank 2, a manual opening and closing valve 3, a high-pressure hose 4, an electromagnetic exhaust valve 7 and an adapter 8. The air tank 2 is fixedly connected to the body 1 of the drone. Optionally, in order to facilitate disassembly and inflation, the air tank 2 can be fixed to the body 1 of the drone by a strap, and one end of the air tank 2 is connected to the manual opening and closing valve 3, and the manual opening and closing valve 3 can inflate the air tank 2 through an external air source. One end of the high-pressure hose 4 is connected to the manual opening and closing valve 3 through a first hose connector 5, and the other end is connected to the electromagnetic exhaust valve 7 through a second hose connector 6. One end of the adapter 8 is connected to the electromagnetic exhaust valve 7, and the other end is connected to the airbag 9, wherein the airbag 9 is folded and placed in the body 1 when not in use, the drone is controlled and connected to the electromagnetic exhaust valve 7, and the airbag 9 is located at the bottom of the body 1 after pushing down the drone cabin cover when in use.

[0020] In this embodiment, the body 1 of the UAV is a mission carrier. The provision of the airbag 9 in this embodiment can assist the body 1 of the UAV to land on the sea surface and provide stable buoyancy.

[0021] In addition, the manual on-off valve 3 is fixed to one end of the gas storage tank 2 through a threaded connection.

[0022] At the same time, one end of the high-pressure hose 4 is threadedly connected to the manual opening and closing valve 3 through the first hose connector 5, and the other end is threadedly connected to the electromagnetic exhaust valve 7 through the second hose connector 6. One end of the adapter 8 is also threadedly connected to the electromagnetic exhaust valve 7.

[0023] Preferably, the air tank 2 is a carbon fiber air tank, and the airbag 9 is a TPU woven airbag.

[0024] When the drone sea landing airbag of this embodiment is used, first open the manual opening and closing valve 3, and inflate the gas tank 2 through an external gas source. After the gas tank 2 is inflated, close the manual opening and closing valve 3, fix the gas tank 2 in the body 1 of the drone, and connect the high-pressure hose 4 to the manual opening and closing valve 3 through the first hose connector 5, then open the manual opening and closing valve 3, and then fold the airbag 9 and put it into the body 1 of the drone. At this time, the drone can enter the ready-to-fly state; when the drone flies to the designated sea area and descends to the designated height, the drone sends a control command to the electromagnetic exhaust valve 7 to open the valve. At this time, high-pressure gas is filled into the airbag 9 through the adapter 8. After the airbag 9 expands, the drone cabin cover is pushed open until the gas is full. Figure 1 As shown, the airbag 9 is partially located at the bottom of the drone body 1. At this time, the drone slowly glides to the sea surface and lands. The airbag 9 can provide a certain buffer force for the drone to descend. After landing on the sea surface, the drone floats on the sea surface with the buoyancy of the airbag 9.

[0025] The drone sea landing airbag of the present invention is based on the original structure of the drone, by adding an airbag and an airbag inflation mechanism. When the vertical distance between the drone and the sea surface reaches a set height, the drone sends an electrical signal to the electromagnetic exhaust valve of the airbag inflation mechanism, thereby inflating the airbag and popping it open. The airbag can provide cushioning when the drone lands, reduce impact force, and protect the structure and equipment of the drone. At the same time, the airbag can also increase the stability of the drone on the sea surface, making it easier to be recovered and reused, so that the drone can operate in the sea area and land smoothly on the sea surface, which can effectively solve the problem of drone landing at sea.

[0026] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
