DESCRIPTION OF THE EMBODIMENTS

(7) The present invention will be more clearly and completely described by means of two preferred embodiments in conjunction with the accompanying drawings hereinafter, but the present invention is not limited to the scope of the embodiments.

Embodiment 1

(8) As shown in FIG. 1, the present invention provides an amphibious drone, comprising a fuselage 1, a linear support 2 and a main wing 3. The amphibious drone is equipped with a take-off and landing device 4, which is provided on the lower surface of one or more of the fuselage 1, the linear support 2 and the main wing 3. The take-off and landing device 4 comprises a buoyancy unit 41 and a power device, and the power device is capable of generating thrust to push the buoyancy unit 41 to move. The installation of the take-off and landing device 4 can realize that the buoyancy unit 41 serves as a buoyancy device to support the drone when the amphibious drone is floating on the water. The take-off and landing device 4 can also be used as a support device when the drone is landing on land. Since the take-off and landing device 4 has its own power device, the power device can directly drive the drone to move and take off and land by driving the buoyancy unit 41 to move.

(9) As shown in FIGS. 2 to 4, further, the take-off and landing device 4 is detachably connected to the fuselage 1 and/or the linear support 2 and/or the main wing 3. The detachable connection allows the drone to detach the take-off and landing device 4 when it does not need to land on water, reducing the weight of the drone to achieve a lighter flight effect. The take-off and landing device is reinstalled before the flight that requires landing on water, and is convenient and practical. In this embodiment, a bump 44 is provided on the take-off and landing device 4, the lower surface of the fuselage 1 and/or the linear support 2 and/or the main wing 3 is provided with a receiving groove 5, and when the take-off and landing device 4 and the fuselage 1 and/or the linear support 2 and/or the main wing 3 are in a connected state, the bump 44 is provided in the receiving groove 5. The bump 44 and the receiving groove 5 are provided to be connected quickly and sufficiently, and can realize the quick disassembly and assembly between the take-off and landing device 4 and the drone body. In other embodiments, other connection methods can also be used, such as lock connection.

(10) The buoyancy unit 41 is an open hollow structure, and at least a part of the power device is located in the intermediate space of the buoyancy unit 41. A part of the power device is installed in the intermediate space of the buoyancy unit 41 to realize that when the power device is started, an air or water flow is formed in the open hollow space of the buoyancy unit 41. The thrust generated by the air or water flow pushes the power device to move forward and then drives the amphibious drone to move forward.

(11) The power device comprises a thruster 42 and a power connector 43, and the thruster 42 is provided in the intermediate space of the buoyancy unit 41. Preferably, the thruster 42 uses a propeller system. The power connector 43 is located at the connection position between the take-off and landing device 4 and the amphibious drone, that is, on the surface of the bump 44. The thruster 42 and the power connector 43 are connected by a power line. A power connector 43 is further provided at the connection position between the fuselage 1 and/or the linear support 2 and/or the main wing 3 and the take-off and landing device 4, that is, on the surface of the receiving groove 5. The power device and the fuselage 1 and/or the linear support 2 and/or the main wing 3 are electrically connected through the connection state of the power connector 43, that is, when they are in the connected state, the bump 44 is located in the receiving groove 5. At the same time, the two power connectors 43 at corresponding positions are in contact with each other, so as to realize the power connection. The power connector 43 is provided to supply power to the thruster 42 through the drone so that the thruster 42 operates. Moreover, because the power is directly supplied by the drone, the power system in the power device is reduced, the possibility of the power system touching water is reduced and the service life is increased.

(12) Further, in this embodiment, the buoyancy unit 41 is a float.

(13) Further, the amphibious drone comprises at least two of the take-off and landing devices 4, and all the take-off and landing devices 4 are symmetrically arranged along the central axis of the amphibious drone. The installation of two or more take-off and landing devices 4 can not only ensure that the drone has a better water surface support effect, but also the increase of the take-off and landing devices 4 strengthens the starting power, and the drone takes off and lands faster. The take-off and landing device 4 can be provided on the lower surface of the fuselage 1, and can be provided directly below the linear support 2 along the central axis of the drone. In this embodiment, while a take-off and landing device 4 is provided on the lower surface of the fuselage 1, two take-off and landing devices 4 are further provided symmetrically below the linear support 2. In other embodiments, a take-off and landing device 4 can also be provided on the lower surface of the wing 3. At the same time, the amphibious drone can also be provided with only one take-off and landing device 4 so that it is located directly below the central axis of the drone to achieve the effect of light structure and quick disassembly and assembly.

Embodiment 2

(14) The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the amphibious drone of the present invention does not comprise the power connector 43. As shown in FIG. 5, the power device 45 comprises the thruster 42 and the main engine 46, the main engine 46 is located inside the buoyancy unit 41, the main engine 46 and the thruster 42 are connected through a power line 47, and the main engine is capable of generating electricity to drive the thruster 42 to move. The main engine 46 is installed in the power device 45, so that the power system is self-powered, providing powerful electricity, and strengthening the operating power of the power device.

(15) Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
