Background
The most obvious difference between the flying automobile and the common automobile is that the flying automobile has the function of flying in the air. With the rise of urban air traffic concepts in recent years, an electric vertical take-off and landing aircraft which is used for solving the problem of urban traffic congestion and only has an air flight function is also called a flying car, and the connotation of the flying car concept is expanded to be a carrier with an air-ground amphibious function or used for urban air traffic.
The prior technical scheme comprises the following steps:
due to the development of modern science and technology, the aerocar can be mainly divided into three categories, namely a folding wing aerocar, a multi-rotor aerocar and a self-rotor aerocar.
1. The aerocar taking off and landing vertically adopts a foldable wing design. When the automobile runs on a highway, the wings can be folded at two sides of the automobile body, the propellers are folded in the fairing, and the automobile can run on the highway like a common civil automobile. In flight mode, the wings and propellers are deployed. The wheels are contracted in the fairing inside the vehicle body, so that the resistance of the wheels during flying is reduced. The flight mode employs the principles of tiltrotor aircraft. During taking off, the double engines are in certain included angle with the horizontal line, so that the double engines can take off and land vertically, and after reaching a certain height, the double engines are gradually rotated to be horizontal to provide continuous power. In addition, the vertical take-off and landing function is realized, the safety coefficient is higher, and the requirement on a take-off field of a road surface is low. But adopt the rotor structure that verts to lead to its cost higher, energy consumption than greatly increased, use cost is high, and is fit for the masses little.
2. The multi-rotor type aerocar adopts the principle of external symmetrical propellers, offsets torque force while providing enough lift force, has the capability of vertical take-off and landing, and is not limited to take-off and landing fields any more. The unmanned aerial vehicle can fly by a planned air route in advance, the limitation on the operation capacity of passengers is low, the misoperation probability is low, and the safety is high. But compared with other flying automobiles, the flying automobile has the advantages of high use cost, low speed, large energy consumption, small voyage and high maintenance cost. Is only suitable for traffic in a small range and short distance
3. The design of the self-rotor aerodyne integrates the functions of an automobile and a motorcycle, and the self-rotor aerodyne can normally run on a road after being folded. After the rotor wing is unfolded, thrust is provided through the propeller at the tail of the collective body, the self-rotating rotor wing rotates to generate lift force, and the running takeoff of 170m is needed. The novel automobile flight control device is high in flight speed and low in requirement on the field, meets the daily requirement of people on automobiles and flight, and has certain practicability. But does not have hovering capability, a vertical take-off and landing function.
In addition, the existing flying automobile has the defects of high manufacturing cost, greatly increased energy consumption ratio, high use cost, small application range and heavy weight due to the limitation of design and technology, cannot meet the requirement of complex scene landing, and has no way of passing through complex terrains in mountains and countries when executing specific tasks, so that the existing flying automobile cannot be effectively applied to the field of military.

In order to facilitate the observation and safe driving of a driver to the surrounding environment during ground driving, the flying motor power source layout adopts a non-square parallel different-plane central symmetry structure. The fan-shaped expandable protective duct is adopted around the propeller; when the vehicle runs on the ground, the transverse size is shortened by adopting a fixed-position propeller-stopping method.
The technical solution of the present invention is described in detail below with reference to the accompanying drawings and examples.
Examples
As shown in fig. 1, the embodiment of the present invention provides a manned flying car with form intelligence. The invention mainly explains a fan-shaped expandable protection duct, fixed propeller and topology fusion frame structure with intelligent form, and solves 2 technical problems in an intelligent form.
1. Intelligent-fan-shaped expandable protection duct
The intelligent detection sensor is applied to the flying vehicle, so that manual operation and control can be reduced, the automation control degree is increased, and the convenience in the aspect of operation and control is improved. The intelligent control system is based on the laser displacement sensor, and judges the distance from the front propeller to the ground according to the action characteristics of the front propeller close to and far from the ground so as to realize the corresponding intelligent control of the fan-shaped expandable protection duct on the propeller. When the aerocar driven on the ground is jammed and rises for 2 meters after the flight mode is implemented, the fan-shaped expandable protection duct rotates out of the inner channel to form a closed loop with the inner channel, thereby protecting the propeller and simultaneously improving the pneumatic performance. After the flight operation of the flying automobile is finished, the descending operation is carried out, and when the distance between the fan-shaped expandable protective duct and the ground is 2 meters, the fan-shaped expandable protective duct can rotate to enter the inner duct so as to avoid friction with other vehicles on the road.
The circumference of the propeller 4 adopts a fan-shaped expandable protection duct design; the fan-shaped expandable protection culvert inner ring 1 is connected with the fan-shaped expandable protection culvert outer ring 2 through a slide rail, and the fan-shaped expandable protection culvert inner ring 1 is positioned on the inner side of the fan-shaped expandable protection culvert outer ring 2.
The shape intelligence of protection duct:
when the vehicle is driven on the ground, the fan-shaped expandable protective culvert inner ring 1 rotates to enter the fan-shaped expandable protective culvert outer ring 2, so that the ground trafficability is improved, the transverse size is shortened, the vehicle can be ensured to run in a single lane of a normal pavement road surface when the vehicle runs on the ground, the running of other vehicles is not hindered, the transportation difficulty is reduced after the vehicle is rotatably stored, the transportation cost is obviously reduced, the size of a die opening is reduced, and the processing difficulty is reduced; when the aircraft drives in the air, after the fan-shaped expandable protection duct inner ring 1 rotates out of the fan-shaped expandable protection duct outer ring 2, the propeller is protected from being influenced by other objects, the propeller can generate larger lift force, and the pneumatic performance is improved.
2. Form intelligence-fixed position oar stopping
When the vehicle runs on the ground, the fan-shaped expandable protection duct inner ring 1 rotates to enter the fan-shaped expandable protection duct outer ring 2, and then the propeller 4 performs fixed-position propeller stopping operation, so that the ground trafficability is improved, the transverse size is shortened, and the vehicle can run in a single lane of a normally paved road surface when running on the ground.
3. Morphological intelligence-topology fusion frame structure
FIG. 2 is a schematic view of the internal structure of the passenger flying vehicle of the present invention.
Because large aircraft have higher requirements on structural strength and rigidity and are extremely sensitive to weight, the chassis of the conventional vehicle is usually designed to have higher weight for ensuring driving comfort and reliability. The topology fusion frame structure adopts the scheme that a main carbon fiber tube is connected with aviation aluminum alloy and local aluminum alloy or alloy steel is welded, and an original chassis functional component, a covering piece and the like are directly arranged on a frame. The upper part of the front rotor wing can shield the sight of the driver for land driving and air operation, so the lower part is arranged; the rear rotor wing is arranged downwards, influences the observation visual field of a rearview mirror of a driver when driving on the ground, and is arranged upwards. Thus a design with front rotor below and rear rotor above results. Along with the improvement of the national requirements on energy conservation and emission reduction, how to apply an advanced structural design technology to carry out structural design on the frame is to realize the weight reduction and the light weight of the frame, so that the increasingly strict national regulation requirements and the lifting force are met, and the method becomes a key factor for the survival of future automobile factories.
In order to better realize the weight reduction task in the lightweight design, the invention abandons the traditional automobile chassis and flight frame in the overall design and designs a new flight driving fusion frame structure.

The frame considers the view safety when the vehicle drives and flies on the ground, and the propellers of the four-shaft eight-propeller aerocar are not arranged on the same plane, but are designed in such a way that the front propeller is arranged from the bottom to the top along with the rear propeller. The front propeller position is positioned under the front glass of the vehicle body in consideration of the reason that the view of the driver is limited. The rear part is positioned at the upper part of the vehicle body in consideration of the problem that the vehicle body collides with a coming vehicle behind.
Because the flying automobile considers the flying requirement, the roof adopts a transparent acrylic plate roof window 11; because the windows on the side of the vehicle body are not limited to the left rear upper window 9 and the left front upper window 12 on the upper part in flight requirements, the lower parts of the windows are also designed into the left lower window 17 and the right lower window (which are not marked in the figure due to the view angle) of the acrylic plate made of transparent materials, and the driving experience is better and the safety is higher.

The flying motor power source layout adopts a non-square parallel non-planar central symmetrical structure, and fan-shaped expandable protection ducts and fixed propellers are arranged around the propellers.
Aiming at the fan-shaped expandable protection duct, the protection duct can be realized by folding the outer propeller cover to the upper part or the lower part of the inner propeller cover along the propeller core, but the stability is poor.
The fixed paddle and the frame part have no alternative scheme temporarily.
