Description

Technical Field

[0001] The invention belongs to the field of aircraft, and in particular relates to a disc-type magnetic levitation helicopter. Background Art

[0002] In recent years, unmanned helicopters have developed rapidly, especially multi-rotor remote-controlled helicopters, which have won a large application market due to their small size, flexible mobility and simple operation. However, with the advancement of electromagnetic technology, problems such as large wind resistance, high energy consumption and large turning diameter of rotor helicopters, including multi-rotor helicopters, have gradually emerged. Summary of the invention

[0003] 1. Problems to be solved The invention provides a disc-type magnetic levitation helicopter. The disc-type magnetic levitation helicopter has a compact structure, a disc-shaped appearance, small flight wind resistance, high energy utilization rate, a small turning radius, and can realize instant turning.

[0004] (II) Technical solutions to the problem The disc-type magnetic levitation helicopter according to the present invention is characterized in that the disc-type magnetic levitation helicopter is composed of a cabin assembly 1, a propeller assembly 2, a steering and speed change assembly 3, a battery assembly 4, a magnetic levitation system 5, and a control system 6.

[0005] The cabin assembly 1 is composed of an electromagnet base ring 11, a cabin belt ring 12, an upper cabin body 13, a lower cabin body 14, a landing gear 15, a gangway 16, a side cabin door 17 and a bottom cabin door 18.

[0006] The electromagnet base ring 11 has a horizontal mushroom head shape on one side when passing through the propeller rotation axis. The mushroom head extends into the U-shaped groove of the hollow hub 21. Circumferential balancing electromagnets 52 and circumferential driving electromagnets 54 are alternately arranged on the top of the mushroom head.

[0007] The propeller assembly 2 is a structure with an axially hollow hub. The propeller blades 22 are arranged on the circumference of the hollow hub 21 and are evenly distributed 360 degrees. The hollow hub 21 is horizontally U-shaped on one side through the propeller rotation axis, and the mouth of the U points to the center of the circle.

[0008] A circumferential outer slide rail 231 and a circumferential inner slide rail 232 are provided on the lower side of the propeller outer cover 23. The steering and speed change assembly 3 is installed on the two slide rails and can move circumferentially along the two slide rails.

[0009] The two sets of steering and speed change components 3 are overall in the shape of a dustpan and are installed on the lower side of the propeller outer cover 23. They can slide circumferentially along the circumferential outer slide rail 231 and the circumferential inner slide rail 232. In the hovering state, the two sets of steering and speed change components 3 are symmetrically distributed 180 degrees on the lower side of the propeller assembly 2. When steering is required, the angle between the two sets of steering and speed change components 3 can be adjusted.

[0010] The steering and speed change assembly 3 can change its angle relative to the circumference of the cabin assembly 1 through its circumferential displacement device 33 to change the direction of the dustpan opening of the steering and speed change assembly 3, so that the disc-type magnetic levitation helicopter will fly in the opposite direction of the dustpan opening of the steering and speed change assembly 3.

[0011] The wind shield bottom plate 31 can change its opening and closing degree under the control of the bottom plate opening and closing device 34 to change the size and speed of the airflow in the dustpan opening direction of the steering and speed change component 3, thereby controlling the flight speed of the disc-type magnetic levitation helicopter.

[0012] A plurality of spherical wheels 151 and a brake device 152 are arranged at the bottom of the landing gear 15, so that the disc-type magnetic levitation helicopter can be temporarily moved and braked on the ground.

[0013] The bottom hatch 18 is used for loading and unloading cargoes of the disc-type magnetic levitation helicopter, and the side hatch 17 and the gangway 16 are used for passengers to enter and exit.

[0014] The control system 6 of the disc-type magnetic levitation helicopter can realize automatic control of the helicopter only by controlling the rotation speed of its propeller blades 22, the circumferential angle of the steering and speed change component 3 relative to the cabin component 1 and the opening and closing degree of the wind shield bottom plate 31, and can realize unmanned driving at low cost.

[0015] (III) Beneficial effects 1. The disc-type magnetic levitation helicopter described in the present invention has a compact structure, a disc-shaped appearance, a small turning radius, and can achieve instant turning.

[0016] 2. During the flight of the disc-type magnetic levitation helicopter described in the present invention, the propeller is in a suspended state under the action of electromagnetic force. During the rotation process, there is no other contact friction except contact with the air, so the energy loss is small and the cruising range is long.

[0017] 3. The steering and speed control of the disc-type magnetic levitation helicopter described in the present invention is achieved by adjusting the circumferential angles of the two steering and speed change components 3 relative to the cabin component 1, and the opening and closing degree of the bottom plate opening and closing device 34. The control and execution mechanism is simple and easy. BRIEF DESCRIPTION OF THE DRAWINGS
