Embodiment 1

[0028] This embodiment provides a ground-air unmanned vehicle whose wheels and ducts are shared, and can freely switch between walking mode and flight mode.

[0029] Such as Figure 1-4 As shown, the ground-air unmanned vehicle shared by the wheels and the duct includes: the body 1, the duct fan 2, the motor A3, the folding device 4, the frame 5, the motor B6, the gear 7 and the landing gear 8.

[0030] The connection relationship between the wheels and the ground-air unmanned vehicle shared by the duct is as follows: the front end of the body 1 is elliptical and streamlined, which can significantly reduce airflow interference; the front and rear directions of the body 1 are vertical, the left and right directions are horizontal, and the up and down directions are vertical The body 1 is a left-right symmetrical shell structure, and its vertical upper end is circumferentially provided with four frames 5 integrally formed with the body 1, wherein the two front frames 5 are symme...

Embodiment 2

[0036] On the basis of Embodiment 1, the flight control and walking controller are located above the interior of the body 1, and the battery is located below the interior of the body 1, which is conducive to reducing the center of gravity of the ground-air unmanned vehicle shared by the wheels and the duct.

Embodiment 3

[0038] On the basis of Embodiment 1 or 2, an inspection window is provided at the bottom of the body 1 to facilitate inspection of the control module and battery replacement.

Abstract

The invention discloses an air-ground unmanned vehicle shared by wheels and a duct. The air-ground unmanned vehicle comprises a vehicle body, a duct fan, a motor A, a folding device, racks, a motor B,a gear and an undercarriage. The vehicle body is in bilateral symmetry state. The Four racks are arranged at the upper end of the vehicle body in the circumferential direction, and the front rack andthe rear rack are bilaterally symmetrical about the vehicle body. An outward end part of each rack is connected with a ducted fan through a folding device; each folding device drives the ducted fan to be switched between a horizontal state and a vertical state through a steering engine A arranged on the rack; a fan in each ducted fan is driven by a motor A; the duct of each ducted fan can be driven by a motor B to rotate independently, and when the ducted fans are vertical, the ducts of the four ducted fans can be in contact with the ground at the same time; a steering engine B is arranged inthe undercarriage and drives the undercarriage, one end of the undercarriage is arranged in the vehicle body, and the other end of the undercarriage can penetrate through a through hole formed in thebottom of the vehicle body to stretch; and a control module is arranged in the vehicle body and makes the motor A and the motor B rotate and the steering engine A and the steering engine B act.

Description

technical field [0001] The invention relates to the technical field of investigation and rescue, in particular to a ground-air unmanned vehicle with wheels and ducts shared. Background technique [0002] In the prior art, the use of quadcopters for indoor detection and rescue has disadvantages such as high noise, susceptibility to airflow interference, and low motion control accuracy, which greatly limits the application of quadcopters; Among them, the speed and obstacle-surmounting ability of unmanned vehicles are poor. Contents of the invention [0003] In view of this, the present invention provides a ground-air unmanned vehicle whose wheels and ducts are shared, which can freely switch between walking mode and flight mode. [0004] The technical solution of the present invention is: a land-air unmanned vehicle that shares the wheels with the duct, including: the body, duct fan, motor A, folding device, frame, motor B, gears and landing gear; [0005] The front end of...
