Adopt rotation structure to realize operating condition's switching, when removing with land walking mode, the actuating arm is through rotating the adjustment to vertical state to reduce the occupation space of horizontal direction, solved the longer ground wing that leads to of traditional aircraft both sides span and extended and fold and the bigger problem of occupation space when run-up takes off, compare in traditional aircraft, can be applicable to ground walking transportation better.
It should be noted that the specific connection mode of each part is conventional means such as bolts, rivets, welding and the like, which are mature in the prior art, the machinery, the parts and the equipment are conventional models in the prior art, and the circuit connection is a conventional connection mode in the prior art, which is not described in detail herein.
Example 3
In yet another exemplary embodiment of the present disclosure, as shown in fig. 1 to 10, a method of operating an air-ground amphibious aircraft as in example 2 is provided.
The method comprises the following steps:
the rotation of the driving arm 5 at the side surface of the supporting arm 3 is controlled by the corner driving motor 504;
when the corner driving motor 504 controls the driving arm 5 to rotate the wheel rim 10 to a state parallel to the chassis 1, the whole machine is in a flying state;
the propeller motor 13 is used for controlling the propeller 4 to generate reverse thrust, so that the whole aircraft ascends or advances;
when the corner driving motor 504 controls the driving arm 5 to enable the wheel rim 10 to rotate to a state vertical to the chassis 1, the whole machine is in a walking state;
at the moment, the wheel motor 14 is controlled to enable the wheel gear 8 and the wheel gear ring 7 to be meshed and driven, and further the whole machine moves forwards.
When the whole aircraft is in a flying state, the wheel rims 10 on the two sides of the chassis 1 are in a horizontal extending state, and when the whole aircraft is in a walking state, the wheel rims 10 on the two sides of the chassis 1 are in a vertical tightening state, so that the whole size of the whole aircraft is reduced, and the whole aircraft can move on the ground conveniently.
The spiral lifting mechanism and the walking mechanism are driven to rotate through the corner driving arm in the rotary driving mechanism, the two wings of the spiral lifting mechanism can freely switch the working states in the horizontal direction and the vertical direction through conversion, and then the form of the whole spiral lifting mechanism is changed on the two sides of the chassis, so that the working state of the spiral lifting mechanism can be freely switched between a flight mode and a land walking mode, and the spiral lifting mechanism is suitable for two working states of a road surface and a flight.
The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure, and various modifications and changes may be made to the present disclosure by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present disclosure should be included in the protection scope of the present disclosure.
