Description

Technical Field

[0001] The invention relates to an air-ground dual-purpose helicopter flying car, which is used for air and ground passenger and cargo transportation, air patrol, air farmland operation, air forest protection, air power wiring operation, air tourism, accommodation and sightseeing, air fitness and parachuting platform and the like. Background Art

[0002] In recent years, the performance of power batteries and electric multi-rotor propeller drone technology have greatly improved. The present invention is based on the patent application "A Helicopter Aircraft" filed by me on January 17, 2003 and authorized (Chinese invention patent application No. 03114968.5), and has made new improvements to the power device and the folding and unfolding method of the horizontal tail. The important parts of its basic configuration are still the same as those of the "03114968.5" invention, including the canard and horizontal tail. The present invention can be regarded as a multi-purpose air-to-ground dual-purpose helicopter flying car. Summary of the Invention

[0003] The purpose of this invention is to utilize a newly designed, matched set of electric propellers. This propeller can achieve vertical takeoff and landing, hovering, and forward flight in the air, as well as taxiing and landing on the ground and driving on ground tracks. The power battery equipped with this device is also used to drive the wheels equipped with hub motors for driving on the ground track. This power battery can be quickly charged or replaced with another set of power batteries to meet the needs of medium- and long-distance aviation, such as continuous point-to-point flights and landings from the air. The technical solution to achieve this purpose is as follows:

[0004] An electric multi-purpose helicopter flying car has electric propellers and retractable front wings and horizontal tail wings. The electric propellers are arranged in groups and their thrust directions are matched according to usage requirements. Each group, for example, has four propellers, which are arranged on the main crossbeams and their brackets perpendicular to the longitudinal fuselage on the left and right sides of the longitudinal middle fuselage of the aircraft fuselage. The propellers are driven by electricity generated by the onboard power battery and the flying carpet-like solar photovoltaic panels deployed and towed in the air at the tail of the aircraft to generate lift or forward thrust. Both sides of the fuselage have rotatable support rods for the main crossbeams. The main crossbeams are also pushed by a horizontal push-pull mechanism arranged in the side walls of the fuselage, so that they rotate in the upper and lower clamping plates like a universal joint, thereby displacing the electric propellers on the main crossbeams and their brackets to generate downward lift or backward forward thrust on the fuselage. Furthermore, the main crossbeam is connected by double rings between its outer and inner sections. When pushed and pulled by the push-pull rod, the sleeve-type connecting component is transformed from an open forward flying state perpendicular to the longitudinal fuselage to a retracted state parallel to the longitudinal fuselage and attached to the side of the fuselage; when flying in the air, the front wing and the horizontal tail are open. When it is necessary to drive like a car on the ground road, the horizontal tail is provided with a movable hinge of a vertical cross-section of a tail close to the left or right rudder of the tail. The tail is centered on the rotatable hinge joint and is driven by the forward or reverse coordinated traction of the cables driven by the electric motor connected in series at the tail support rod and several force points arranged in front and rear of the tail rudder and on the lower surface of the middle part of the rotatable tail. The tail is transformed from a horizontal state to a forward vertical state close to the side of the longitudinal fuselage at the outermost position. In this retracted state, the aircraft can drive on the ground lane like an ordinary car.

[0005] The utility model relates to a multi-purpose flying carpet platform of an electric multi-purpose helicopter flying car. It is arranged and configured based on the tailgate at the rear of the aircraft and the spatial structural components around the tailgate. It uses light and flexible multiple sections or multiple rods to form an airbag bag that can be rolled and deployed toward the rear of the aircraft in the air or retracted by a cable attached to its surface. The outer shell of the airbag bag is a double-layer airbag layer with an inflated airbag layer inside. A ventilation inlet and outlet air cylinder channel is provided from the tailgate of the aircraft to the usable space inside the airbag bag. A plurality of solar photovoltaic panels are provided on the upper surface of the large rectangular flying carpet bag. A capsule-type sleeping blanket and a transparent landscape glass window are provided inside the airbag bag. The airbag bag also has an inlet and outlet tailgate for the occupant to perform mid-air parachute jump. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The technical solution of the present invention is further described with reference to the following drawings:

[0007] Figure 1 It is a three-dimensional schematic diagram of a helicopter flying car;

[0008] Figure 2It is a schematic diagram of the displacement structure of the main beam with four electric propellers on each side of the fuselage;

[0009] Figure 3 It is a schematic diagram of the structure of the horizontal tail being folded or extended;

[0010] Figure 4 The tail of a helicopter flying car can be flexibly deployed in the air. The upper surface of the towed vehicle is equipped with photovoltaic solar cells. The outer shell is an inflatable double-layer flying carpet. The interior of the flying carpet is equipped with a capsule-style passenger cabin bed. The basic structural diagram of this flying carpet also serves as an aerial parachute platform.

[0011] Figure 1 "1" is the electric propeller; "2" is the horizontal tail; "3" is the strut supporting the horizontal tail; "4" is the left front wheel; "5" is the rudder; "6" is the fuselage; "7" is the cockpit at the front of the fuselage; "8" is the canard; "9" is the bracket for the electric propeller "1"; "10" is the main crossbeam of each group of 4 electric propellers on the left or right side of the fuselage, which can be rotated 90 degrees forward and backward respectively, so as to transform the electric propellers at the four corners mounted on the bracket "9" in a horizontal position as shown in the figure, which blow air downward to generate lift for the fuselage, into a vertical position with 2 upper and 2 lower propellers blowing air toward the rear of the fuselage to make the aircraft fly forward.

[0012] Figure 2"11" is a load-bearing structural thick plate arranged on the side walls on both sides of the middle of the fuselage, each of which has a bearing for supporting the main crossbeam; "12" is the outer section of the main crossbeam, which is pushed by the push rod "13" and can be rotated 90 degrees; the main crossbeam uses two high-strength circular rings "14" to connect the outer section with the inner section in a mutually perpendicular and interlocking manner. When the main crossbeam is pushed forward by component "13" and rotated 90 degrees, the outer section of the main crossbeam is in a horizontal state due to one of the rings of "14". The connection method includes the support of its upper and lower two plywoods, so that the outer section is in a perpendicular state to the longitudinal fuselage. The main crossbeam is driven by the rotation of the active lower end of the support rod "15" at the bottom of the main crossbeam and gradually approaches the rear fuselage side horizontally. At this time, the four electric propellers on each side are in a state where the propeller blades of two upper and two lower ones are perpendicular to the ground, so they can be close to and vertically When the main beam rotates up and down and is in a horizontal position, the longitudinal horizontal push rod in the side wall of the fuselage that moves back and forth in the groove can push the diagonal support rod "16" forward, thereby also pushing the main beam forward from the state close to the longitudinal side wall of the fuselage to the state perpendicular to the longitudinal fuselage. At this time, pushing the outer side of the main beam forward into place can enable the four electric propellers on each side to blow air downward to make the aircraft enter a vertical ascent working condition, and then rise to a suitable height. At this time, the main beam and its bracket are pressed Figure 2 When the aircraft is rotated forward 90 degrees in the direction indicated by the middle arrow "17" and brought into a state perpendicular to the ground, each electric propeller blows air toward the rear of the aircraft, thereby generating thrust for forward flight.

[0013] Figure 3"18" is a rotatable and flexible pivot joint point for rotating the horizontal tail, which is located at a lateral position close to the vertical cross-section of the tail; the cable "18" driven by the electric motor is connected in series to at least three force points "19", so that the tail can rotate around the force point "18"; "20" is a flexible and rotatable articulated component of the tail support rod. When the cable is pulled and moved from the force point "19" to the force point "21", it drives the outer section of the displaceable horizontal tail to tilt forward and gradually change to a vertical state close to the side wall of the fuselage. At this time, the support rod is also pulled and rotated by virtue of its flexible block-shaped connecting surface set on the lower surface of the outer section of the horizontal tail, thereby jointly putting the tail in a vertical state. At this time, there is also a cable pulled from the positioning force point "22" of the tail above, which together with the support rod and the flexible rotating pivot forms a multi-point positioning state, so that the tail can switch between the horizontal and vertical states. When the tail is in a vertical position, it is located at the outermost left and right sides of the longitudinal fuselage, and contains two electric propellers and their blades in a vertical position close to the sides of the fuselage. During takeoff, the front wings and horizontal tail are first spread out, and then the main crossbeam is rotated outward to a position perpendicular to the longitudinal fuselage. The main crossbeam is then rotated to adjust the blades of the four electric propellers on each side to a horizontal position. The propellers are started to generate upward lift, causing the aircraft to rise vertically. The blades of each electric propeller are then turned to a vertical position, and air is blown backward to generate thrust to make the aircraft fly forward.

[0014] Figure 4 "23" is an openable door at the tail of the aircraft; "24" is a horizontal bar of the airbag structure that is laid down and connected to the outside of the structure on both sides of the tail. This horizontal bar is connected to the door "23" at the tail of the aircraft. The inflatable double-layer large-area rectangular airbag is rolled and unfolded by the horizontal bar "22". The tail door "23" is provided with an oblong ventilation cylinder with a sealed outer surface leading to the interior of the airbag, which is suitable for crawling forward in a lying position. The airbag enters the interior through the cylinder. The airbag is provided with a horizontal bed and a transparent window. The airbag also has an openable and closable door at its tail. Passengers equipped with parachutes can leave the aircraft through this tail door and slide backward into the air to parachute and land.

[0015] The tail airbag is equipped with multiple lightweight and resilient frame members at its edges. These can be rolled horizontally into a tube and then unrolled backwards, retracted and retracted using a cable. During flight, the airbag, unfolded horizontally like a flying carpet, generates upward lift, allowing it to carry passengers or objects of appropriate weight for various activities. Solar photovoltaic panels are mounted on the large upper surface of the airbag, generating electricity that charges the power battery, extending the aircraft's flight time and enabling long-distance flight. The airbag can also perform multiple point-to-point flights, recharging at the landing site or connecting to a battery pack before continuing its flight.

[0016] Effect:

[0017] Compared with conventional multi-rotor propeller drones, the electric aircraft of the present invention has wings that generate lift when flying in the air, which has significant practical and multi-purpose effects of saving electricity, achieving more economical and practical flight costs, and longer flight time.

[0018] Manufactured in accordance with aircraft airworthiness standards and managed and used in accordance with aircraft standards.
