Abstract

A flying car comprises a body (3), a cockpit (26), a passenger cabin (24), a baggage compartment (22), an equipment compartment (18), a vehicle body tail (16), wheels (21, 27), airfoils (5) and a propeller (11). As the combined longitudinal section of the body (3) and the vehicle body tail (16) is in the shape of the airfoil's (5) section, the body (3) can also generate lifting force when the flying car runs on a road surface and flies in air, therefore the area and the wingspan of the airfoils (5) can be relatively reduced under equal load conditions. The airfoils (5) are mounted on hollow flat columns (4) at two sides of the top face of the body (3), and are a certain distance from the curved top face of the body (3). When two ends of the airfoil (5) are folded downwards, the length, the width and the height of the outline of the flying car are smaller than those of a bus, so that the flying car can safely and freely take off, land and run on an expressway.

Description

Flying car

The present application claims priority to Chinese Patent Application No. 201410071053.2, entitled "Flying Vehicle", filed on February 28, 2014, the entire disclosure of which is hereby incorporated by reference in All related applications for which they are disclosed are an integral part of this application.

Technical field

The present invention relates to a "flight car" which can travel on city streets, highways and highways like ordinary cars, and can fly in the air like an airplane. It is mainly due to the technical solution of this flying car to solve the functional requirements of taking off and landing on generally better straight roads. It can take off and land in the straight sections of urban streets and ordinary roads, and it can also be at high speed. The straight section of the road takes off and land. Therefore, the technology of the present invention belongs to the technical field of the automobile industry and belongs to the technical field of the aviation industry.

Background technique

At present, most of the flying vehicles known on the Internet are products developed by the United States and European countries. Most of them are in the research and development stage, and the carrying capacity is small. Most of them can only sit two people, and the wingspan after the folding wings are deployed is 8 meters. Above, this is more difficult for ordinary highways to take off and land, even in two-way four-lane highways. There may be tall trees or utility poles on either side of the road, and steel guardrails and traffic signs on both sides of the four-lane highway. There are also separate steel fences along the road centerline and shrubs about 1.6 meters high. The two lanes on each side are 3.5×2=7.0 meters wide, plus the outermost short stop lane is 2.0 meters wide, and the total width is only about 9.0 meters, so after subtracting 8.0 meters, only 1.0 meters remaining width, so the wing Only 0.5 meters from the roadside barrier at both ends The speed of the flying car is also about 100 km / h or more, so the existing flying car is difficult to take off and land on the two-way four-lane highway. Nowadays, cars are basically popularized in ordinary people's homes in China. Not only are the cities often congested, but sometimes there are congestions on the highways. Therefore, people hope to have flying cars that can safely take off and land on streets and highways. When car congestion occurs, people can choose to fly over the highway from the congestion point and then land on the road to continue, or simply fly from the air to the destination. In addition, the existing flying car wings are fixedly mounted on the vehicle body, and the lift force when taking off and landing is limited, and the required running distance is long.

Summary of the invention

In order to overcome the above-mentioned shortcomings of the existing flying vehicles, the present invention provides an improved flying vehicle which is characterized in that according to the aerodynamic principle, the body can also generate lift when flying in the air; Set at a distance above the body, so under the same load conditions, the lift generated by the wing can be reduced, so the wingspan of the flying car can be reduced to less than 6 meters, compared to the above-mentioned existing flying car, both ends of the wing Steel fences, shrubs or traffic signs on both sides of the expressway can reach 1.5 meters or more indirectly. In this way, it is possible for the flying car to take off and land freely on the highway, and the safety has also been greatly improved. In addition, the angle of attack of the wing of the flying car of the present invention can be changed by rotation. Therefore, when the takeoff and landing are performed, the front edge of the wing is turned up to increase the angle of attack of the wing, and the increase of the lift can reduce the speed requirement during the takeoff and landing, thereby shortening. The distance to run.

The technical solutions adopted by the present invention to solve the technical problems thereof are as follows:

a flying car that includes the body, wings, vertical tail, engine and wheels, etc. The components and their ordered combination; the longitudinal section of the automobile body is made into the shape of the aircraft, and the tail end of the vehicle body can be rotated up and down; the plane of the vehicle body is arranged from front to back in order of the cockpit, the passenger cabin, the luggage compartment, the equipment compartment and the tail of the vehicle body. The wing is not directly mounted on the vehicle body, but is mounted on the hollow flat column on both sides of the vehicle body, and the two sides of the wing can be folded downward at the position opposite to the two sides of the vehicle body; the propeller driven by the engine is placed on the top surface of the vehicle body. unit. In the above technical solution, the plane of the vehicle body is elongated, the longitudinal section of the vehicle body is a cross-sectional shape of the aircraft wing, and the rear end of the vehicle body is made of a tip and a small, poorly used body tail that can be rotated up and down. component. This tail is both an important part of the lift of the flying car body and a horizontal tail for the flying car to control the pitch of the car. Moreover, when the flying car takes off and land on the road, in order to lift the front part of the vehicle body to increase the lift, the tail of the vehicle body must be rotated upward, so that the tail of the vehicle body can be rotated to reduce the risk of rubbing the tail of the vehicle body. Since the longitudinal section of the flying car is a cross-sectional shape of the wing, the car can also be lifted when the car is moving forward, and the lifting side plates are added to both sides of the car top to make the upper and lower pressure difference of the car body larger. Some, so the lift generated by the body will be even larger. When the flying car is driving on the road, because the fuselage will generate some lift, it can reduce the pressure on the road from the flying car. It is equivalent to sitting in the car for 5 people, but the pressure on the ground is reduced, it seems that the car only sits 3 - 4 people the same, thus saving fuel. When a flying car is flying in the air, due to the lift generated by the body, the wing can be made smaller than the existing flying car under the same load conditions, which is beneficial to reduce the span width and make the flying car safer and more convenient. The road takes off and landing.

In the above technical solution, the wing is not directly mounted on the vehicle body, but is mounted on the hollow flat column on both sides of the vehicle body, and the wing is at the opposite side positions of the vehicle body. Can be folded down. In order to meet the requirements of the "flying car" for long-term driving on the expressway, the width of the folded body of the flying car can not exceed the width of the bus; similarly, the height of the wing after folding can not exceed the height of the bus. . Due to the special design of the body of the present invention, the wing can be relatively small, so that when the flying car of 4-12 people is used, the wing width can be controlled below 6 meters and the height can be controlled below 3.0 meters. Since the flying car has a length, a width and a height smaller than that of the existing bus after the wing is folded, the flying car can travel on the body street, the road and the highway like a normal car, so the technical solution of the present invention is Feasible and practical. In addition, the wing is mounted on a hollow flat column, and the hydraulic cylinder installed in the hollow flat column can tilt the wing up and down, so that when the flying car takes off and land, the front end of the wing greatly increases the lift of the wing. Therefore, the approach speed of the flying car can be reduced, and the distance of the flying car on the road can be greatly shortened accordingly.

In the above technical solution, the flying car has two working conditions, one of which is that the flying car is flying in the sky, and the other is that the flying car is driving on the road surface. Both operating conditions use the same engine. The engine can use the existing piston-type car engine. The flying car can be refueled conveniently and conveniently at the car stations all over the country like ordinary cars. By changing the connection with the engine through the shifting frame, it becomes two transmission structures, thereby realizing the functional requirements required to satisfy the above two operating conditions.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", The orientation or positional relationship of the "top", "bottom", "inside", "outside" and the like is based on the orientation or positional relationship shown in the drawings, and is merely for the convenience of describing the present invention and simplifying the description, rather than indicating or implying The device or component referred to must have a particular orientation, is constructed and operated in a particular orientation, and thus is not to be construed as limiting the invention.

In the description of the present invention, it should be noted that the terms "installation", "connected", and "set" should be understood broadly, unless otherwise explicitly defined and defined, for example, may be fixedly connected, set, or Removable connection, setup, or integral connection and setup. The specific meaning of the above terms in the present invention can be understood in a specific case by those skilled in the art.

In the example of the flying car shown in FIG. 1, the combined longitudinal section of the body 3 and the body tail 16 is a cross-sectional shape of the wing, which arranges the radar cabin 1, the electronic instrument cabin 2, the cockpit 26, the luggage compartment 22, and the like from the front to the rear. Equipment bay 18, and body tail 16. The wing 5 is mounted above the hollow flat column 4. The paddle housing 10 and the propeller 11 are in turn mounted above the transmission slot 9 above the equipment bay 18, while the vertical tail 13 is mounted behind the lift side panel 7. Since the longitudinal section of the body 3 is a cross-sectional shape of the wing, the body 3 can also generate lift when the flying car is flying in the air, that is, the body 3 is not only a container for loading and loading, but also has a function of a wing. In addition, vertical lifting side plates 7 are provided on both sides of the curved top of the body 3, and the lifting side plates 7 can be limited when the flying car is flying in the air. The air flow on the top of the body 3 moves to both sides, so that the pressure difference between the bottom plate 34 of the body 3 and the curved top thereof is increased, so that the lift generated by the body 3 is greater, so the flying car is more efficient than the existing flying car. .

As can be seen in Figure 2, the planar cross-sectional arrangement of the body 3 arranges the radar cabin 1, the electronic instrument bay 2, the cockpit 26, the luggage compartment 22, the equipment bay 18 and the body tail 16 in order from front to back. The tail end 30 of the body tail 16 is connected to the rear of the equipment compartment 18 via the rotating shaft 6, and can rotate around the rear end of the body 3, so that it can double the horizontal tail of the flying vehicle to operate the flying car. Pitch state. The cockpit 26, the luggage compartment 22, and the equipment compartment 18 are all provided with a hatch 29.

3 to 6 are views respectively showing the side, top, front and rear directions of the wing 5 of the flying car (5-seat) of the present invention unfolded to both sides. Wherein the two ends of the wing 5 of Fig. 5 are horizontally unfolded, and the ends of the wing 5 of Fig. 6 are slightly tilted upwards, which has the advantage that the flying car is taken off and landed on the highway, relative to the wing of Fig. 5. It is not easy to touch the steel guardrails or the isolation green belts on both sides of the expressway at both ends.

7 to 9 are side, front and rear views, respectively, of a flying car (5-seat) wing 5 of the present invention when it is folded on a highway, a street, or an upper road. The fuselage tail 16 in Figure 7 is in a horizontal state, and when it is traveling on a highway, it produces a greater lift. 8 and 9 show the case where the two ends of the wing 5 are folded downward and the wing 5 is magnetically fixed by the electromagnetic wing system 23 mounted on the bottom plate 34, so that the flying car does not end at both ends of the wing when driving on the road. Swinging.

Figure 10 shows the flight of a flying car on a highway. When the flying car accelerates on the road, people use the hydraulic cylinder 15 to manipulate the body tail 16 to turn up. When the hydraulic action cylinder 15 installed in the hollow flat column 4 is used to lift up the wing 5, the body is raised and the front wheel is off the ground. When the speed is getting faster and faster, the lift is getting bigger and bigger, and the four wheels of the flying car are all off the ground.

Fig. 11 is a longitudinal sectional view of a vehicle of a flying car (10 seats), and Fig. 15 is a plan view of a vehicle body of a flying car (10 seats). It is similar to the five-seat flying car, except that because there are more people on the ride, the lift is required to increase, and the wing 5 becomes two.

Figure 13 is a cross-sectional view showing the folding wing of the flying car of the present invention locked by the electromagnetic wing on the side of the vehicle body. In the figure, the lower end of the wing 5 is provided with a wrought iron piece 33. When the electromagnetic wing system 23 installed in the bottom plate 34 is energized, a strong magnetic force will firmly hold the wrought iron piece 33, so that the flying car can travel on the road. The ends of the wing 5 do not swing.

It is shown in Figs. 14 and 15 that the flying vehicle uses only one engine 8, and the shifting frame 14 is operated up and down by the hydraulic cylinder 15. When the shifting frame 14 controls the looper bevel gear 35 to be connected downwardly to the bevel gear 20 on the output shaft of the engine 8, the looper gear 35 passes through the spline shaft 12 and the two bevel gears 20 mounted in the paddle housing 10. The propeller 11 is rotated, and the flying car enters the flight function state. When the shifting frame 14 controls the looper gear 35 to be connected upwardly to the bevel gear 20 on the output shaft of the engine 8, the looper gear 35 passes through the spline shaft 12 and the bevel gear 20 and the drive shaft 19 mounted under the engine. The rear wheel 21 is driven to rotate, and the flying car enters the vehicle function driving state at this time.

The figure also shows that the fuel tank 17 specially made according to the shape of the rear of the equipment compartment 18 is installed at the rear of the equipment compartment.

16 and 17 show that the flying car wing 5 of the present invention is turned upside down. In the action state, the upper side of the wing 5 is turned up by the hydraulic action cylinder 15 installed in the hollow flat column 4, and when the vehicle speed is getting faster, the lift required for the flying car is getting larger and larger. 18 and 19 show the up-and-down turning state of the tail 16 of the flying vehicle body of the present invention. As can be seen from the figure, the hydraulic cylinder 15 mounted on both sides of the equipment compartment 18 penetrates into the tail 16 of the vehicle body and is stiffened therein. When the piston of the hydraulic cylinder 15 is contracted toward the equipment compartment, the body 16 is pulled to a state perpendicular to the ground. It can also be seen from the figure that the inner wheel casing 28 below the equipment bay 18 is different from the inner wheel casing 28 of the front wheel, that is, it is not semi-circular, but is inclined at an angle to the rear, so that the flying car is moving When driving or flying, the resistance of the front airflow to the body 3 is reduced, thereby improving the efficiency of the flying car, that is, saving fuel and increasing the range.

While the embodiments of the present invention have been shown and described, the embodiments of the invention may The scope of the invention is defined by the claims and their equivalents.
