Embodiment 1

[0043]The land-air amphibious UAV includes a fuselage main body 1; the fuselage main body 1 is provided with a storage mechanism; the fuselage main body 1 is provided with driving mechanisms in pairs; the storage mechanism is used to drive the driving mechanism to make The running gear is extended or stowed. As can be seen from the above structure, the fuselage main body 1 is the main flight part of the UAV, and traveling mechanisms are arranged in pairs on the fuselage main body 1. When the driving mode is converted to the flight mode, the storage mechanism is used to drive the movement of the driving mechanism, and the driving mechanism is stored in the main body 1 of the fuselage. Although the flying part carries the ground driving part, the outer dimensions of the flying part of the UAV remain unchanged. Or the change is very small, it will not affect the airflow flow field, and will not damage the aerodynamic performance of the flying part; the traveling mechanism may be ...

Embodiment 2

[0045] On the basis of the first embodiment, when the traveling mechanism is stored, it is attached to both sides of the main body 1 of the fuselage; when the traveling mechanism is extended, it is folded downward relative to the main body 1 of the fuselage. It can be seen from the above structure that when the land-air amphibious UAV is converted from the ground driving mode to the flight mode, the driving mechanism is stored and attached to both sides of the fuselage body 1 to form a complete flying part. Although the flying part carries the ground driving part, However, it will not affect the air flow field and will not destroy the aerodynamic performance of the flying part; driving dynamics.

[0046] The traveling mechanism includes a folding fuselage part; the folding fuselage part is hinged to the fuselage main body 1; It can be known from the above structure that the folding fuselage parts on both sides of the fuselage body 1 can be folded relative to the fuselage body...

Embodiment 3

[0049] See attached Figure 1-11 . On the basis of Embodiment 1, the traveling mechanism includes a storage arm 2 and a traveling frame 3; the receiving arm 2 is connected to the traveling frame 3; To the bottom or top or both sides of the main body 1 of the fuselage. It can be seen from the above structure that the fuselage main body 1 is the main flying part of the UAV, which can adapt to working environments such as battlefield reconnaissance, search and rescue, geological exploration, high-altitude photography, etc., and avoid large obstacles or bad road sections with many sand and gravel. When the land-air amphibious UAV is converted from the ground driving mode to the flight mode, the storage mechanism on the fuselage body 1 drives the vertical storage arm 2 to move, and the two vertical storage arms 2 carry two driving frames respectively. 3 close to the fuselage main body 1, for example, all the traveling frames 3 can be hidden in the fuselage main body 1 from the bo...

Abstract

The invention discloses an air-ground amphibious unmanned aerial vehicle and a flight control method thereof, and belongs to the field of unmanned aerial vehicles. The unmanned aerial vehicle comprises a vehicle main body; a storage mechanism is arranged on the vehicle main body; traveling mechanisms are arranged on the vehicle main body in pairs; and the storage mechanism is used for driving a running mechanism to act, so that the running mechanism extends or is stored. During taking off, when the set height is reached, the running mechanism is converted into the storage state from the stretching state; and during landing, if the height is lower than the set height, a traveling mechanism is converted from the storage state to the stretching state. According to the land-air amphibious unmanned aerial vehicle and the flight control method thereof, the ground driving part can be stored in the air flight part, the air flow field cannot be affected, the aerodynamic performance of the flight part cannot be damaged, the air function in land-air amphibious is highlighted, only road surface driving is used as an auxiliary mode, the weight of a road surface driving structure is reduced to the maximum degree, the load of a flight part is reduced, flight time is prolonged, and the flight maneuverability is improved.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and in particular relates to land-air amphibious unmanned aerial vehicles and a flight control method thereof. Background technique [0002] In order to solve the problem that model cars or small mechanical vehicles in special industries can only drive on the road in the working environment of battlefield reconnaissance, search and rescue, geological exploration, high-altitude photography, etc., and cannot continue to work when encountering large obstacles or bad road sections with a lot of sand and gravel, and The use of existing aircraft is obviously affected by the weather, and often cannot be used when the wind is strong, and due to the disadvantages of the small battery capacity that the aircraft has a limited flight time in the air, a variety of land and air amphibious robots have emerged in recent years. [0003] For example, a kind of land-air amphibious intelligent vehicle mention...
