Embodiment 1

[0037] combine figure 1 , figure 2 and image 3, a self-service convertible ground-air dual-purpose aircraft in this embodiment includes an aircraft body, a conversion drive mechanism, and a landing support mechanism. The aircraft body is a quadrotor aircraft, and the upper part is provided with a power supply module, a flight control module, and a GPS positioning module. , and can also be equipped with corresponding shooting devices, signal detection and detection devices, rescue devices, etc. according to needs, and there is no special restriction on the usage.

[0038] The installed rotor of the aircraft body of this embodiment is a wheeled rotor. The wheeled rotor includes a rotor motor, rotor blades 104 and a rim 105. The rotor motor is fixed at the two ends of the rotor beam 101, and the rotor blades 104 are connected with the rotor motor shaft. The outer end of the blade 104 is fixedly connected with the rim 105 , and the outer surface of the rim 105 is engraved with...

Embodiment 2

[0049] A self-convertible ground-air dual-purpose aircraft of this embodiment has the same basic structure as that of Embodiment 1, the difference being that this embodiment controls the lifting movement of the lifting screw 407 through gear meshing, and it can also be realized in other ways. Lifting, in this embodiment, the gear meshing control is mainly used as an example. Specifically, the third motor 404 is fixed on the frame bottom plate 106 at the bottom of the aircraft body, the output shaft of the third motor 404 is equipped with the first lift gear 405, and the frame bottom plate 106 is connected with the second lift gear 406 through bearings, so that the second lift gear 406 The two lifting gears 406 can rotate relative to the frame bottom plate 106, but cannot move axially. The first lift gear 405 meshes with the second lift gear 406 .

[0050] The middle part of the second lift gear 406 has a threaded hole, that is, the inner wall of the middle part of the second ...

Embodiment 3

[0053] combine Figure 6 , a self-service convertible ground-air dual-purpose aircraft of this embodiment, its basic structure is the same as that of Embodiment 2, the difference is that the landing gear in this embodiment is mainly composed of three frame support rods arranged at equal intervals 401, the frame support bar 401 is connected into one body through the support bar horizontal frame 403, and the length of the junction is equal to that of the three rack support bars 401. Cover, thereby the lifting screw rod 407 is rotationally connected with the landing gear. If the length of the frame support bar 401 is larger, a through hole can be opened at the position corresponding to the frame top plate 102 and the frame bottom plate 106, and the support bar cross frame 403 is positioned above the frame top plate 102. Affect the rack top plate 102, the structure design is reasonable.

[0054] When performing missions in the field, you may encounter soft soil or partially unev...

Abstract

The invention discloses a self-help switching type air-and-ground dual-purpose aircraft and belongs to the field of aircrafts. The aircraft mainly comprises an aircraft body, a switching driving mechanism, a taking-off and landing supporting mechanism and the like, wherein wheel rotors of the aircraft body are fixed at two ends of rotor cross beams; the switching driving mechanism controls the rotor cross beams to rotate through gear meshing, so that the wheel rotors are switched horizontally and vertically; the taking-off and landing supporting mechanism comprises a third motor, a lifting screw and a landing gear, the third motor is fixed on the aircraft body, the landing gear is rotationally connected with the lifting screw, and the lifting screw is driven by the third motor to perform lifting movement relative to the aircraft body. The landing gear having a lifting function is arranged on the aircraft body, so that the aircraft can be switched automatically between a flying mode and a ground driving mode, has the high intelligent degree and is applicable to field investigation.

Description

technical field [0001] The invention relates to the technical field of aircraft, and more specifically, relates to a self-convertible ground-air dual-purpose aircraft. Background technique [0002] Quadrotor aircraft is a relatively common and classic small aircraft, which is widely used in technical fields such as military reconnaissance, resource survey, and civil aerial photography. The aircraft is compact in structure and flexible in movement, and is suitable for use in narrow spaces or complex environments. In some specific situations, aircraft landing and reconnaissance are required, such as small spaces such as inside buildings, grass and forests. In order to realize the multi-functional development of aircraft, so that it can not only take pictures on land, but also conduct observation and reconnaissance from the air, the concept of land-air dual-purpose aircraft was proposed, and it has been well developed in recent years. However, the structure of the air-ground ...
