Description

A manned flying car with morphological intelligence

technical field

The invention relates to the technical field of flying cars, in particular to a manned flying car with morphological intelligence.

Background technique

The most obvious difference between a flying car and an ordinary car is that it has the function of flying in the air. In recent years, with the rise of the concept of urban air transportation, the electric vertical take-off and landing aircraft that only has the function of flying in the air is also called flying car, which is used to solve the problem of urban traffic congestion. vehicles for urban air traffic.

The existing technical solutions include:

Due to the development of modern science and technology, flying cars can be mainly divided into three categories: folding-wing flying cars, multi-rotor flying cars, and spin-wing flying cars.

1. The vertical take-off and landing flying car adopts a foldable wing design. When driving on the road, the wings can be folded on the sides of the body, and the propellers can be folded in the fairing, which can be driven on the road like an ordinary civilian car. When in flight mode, the wings and propellers are deployed. The wheels are retracted inside the fairing inside the car body, reducing the drag of the wheels during flight. The flight mode adopts the principle of tilt-rotor aircraft. When taking off, the twin engines bear a certain angle with the horizontal line, so that it can take off and land vertically. After reaching a certain height, the twin engines gradually turn to the level to provide continuous power. In addition, it has the function of vertical take-off and landing, which has a higher safety factor and lower requirements for the take-off site on the road. However, the use of the tilt-rotor structure leads to its high cost, greatly increased energy consumption ratio, high use cost and small adaptability.

2. The multi-rotor flying car applies the principle of an external symmetrical propeller, which can offset the torque force while providing sufficient lift, and has the ability to take off and land vertically, which is no longer limited to take-off and landing sites. It can conduct unmanned flight through pre-planned routes, with low restrictions on the operating ability of the occupants, low probability of misoperation, and high safety. However, compared with other flying cars, its use cost is high, the speed is slow, the energy consumption is large, the range is small, and the maintenance cost is high. Only suitable for small-scale traffic, short-distance travel

3. The design of the spin-wing flying car integrates the functions of cars and motorcycles at the same time. After the rotor is folded, it can drive normally on the road. After the rotor is deployed, thrust is provided by the propeller at the tail of the collective, so that the rotor rotates to generate lift, which requires a 170m run to take off. It flies fast and has low demand for venues. It meets people's daily needs for cars and flying, and has certain practicability. But it does not have hovering ability, vertical take-off and landing function.

In addition, due to the limitations of its design and technology, the existing flying cars not only have high construction costs, greatly increase the energy consumption ratio, high use costs, small size and weight, but also cannot meet the requirements of landing in complex scenarios. When performing specific tasks, there is no way to pass through the mountainous and rural complex terrain, so it cannot be effectively applied in the military field.

In order to facilitate the driver's observation of the surrounding environment and safe driving when driving on the ground, the layout of the motor power source for the flight adopts a non-square parallel and out-of-plane center-symmetric structure. The fan-shaped expandable protective duct design is adopted around the propeller; the horizontal dimension is shortened by stopping the propeller at a fixed position when driving on the ground.

The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

Example

As shown in FIG. 1 , an embodiment of the present invention proposes a manned flying vehicle with morphological intelligence. The invention mainly describes the fan-shaped expandable protective duct, fixed paddle and topology fusion frame structure with intelligent form, and solves two technical problems with intelligent form.

1. Form intelligence - fan-shaped expandable protective duct

The flying car uses intelligent detection sensors, which can reduce manual manual control and increase the degree of automatic control, thereby improving the convenience of control. Based on the laser displacement sensor, the invention judges the distance from the ground according to the action characteristics of the front propeller approaching and moving away from the ground, so as to realize the corresponding intelligent control of the fan-shaped expandable protective duct on the propeller. When the ground-driven flying car encounters congestion, after the flight mode is implemented, when it rises 2 meters, the fan-shaped expandable protective duct will rotate out of the inner channel to form a closed loop, which protects the propeller and improves the aerodynamic performance. After the flight operation of the flying car is completed, the landing operation is carried out. When the distance is 2 meters from the ground, the fan-shaped expandable protective duct will rotate into the inner lane to avoid friction with other vehicles on the road.

The fan-shaped expandable protective duct design is adopted around the propeller 4; the fan-shaped expandable protective duct inner ring 1 and the fan-shaped expandable protective duct outer ring 2 are connected by sliding rails, and the fan-shaped expandable protective duct inner ring 1 is located in the fan-shaped expandable protective duct. The inner side of the ducted outer ring 2.

The form intelligence of protective ducts:

When driving on the ground, the inner ring 1 of the fan-shaped expandable protective duct rotates into the outer ring 2 of the fan-shaped expandable protective duct. In order to improve the ground passability and shorten the lateral dimension, it can ensure that the road can be driven in a single lane with normal pavement when driving on the ground. It does not hinder the driving of other vehicles. After being rotated and stored, it not only reduces the difficulty of transportation, but also significantly reduces the transportation cost, but also reduces the size of the mold opening and reduces the difficulty of processing; when driving in the air, the fan-shaped expandable protective duct inner ring 1 rotates out of the fan-shaped shape to expand After protecting the ducted outer ring 2, the propeller can be protected from the influence of other objects, and the propeller can also generate more lift and improve the aerodynamic performance.

2. Form intelligence - stop paddle at a fixed position

When driving on the ground, after the inner ring 1 of the fan-shaped expandable protective duct rotates into the outer ring 2 of the fan-shaped expandable protective duct, the propeller 4 will perform the operation of stopping the propeller at a fixed position, in order to improve the ground passability and shorten the horizontal dimension. It can ensure that the road is driven in a single lane with normal pavement when driving on the ground.

3. Form intelligence-topology fusion frame structure

FIG. 2 is a schematic diagram of the internal structure of the manned flying vehicle of the present invention.

Because large aircraft have high requirements on structural strength and rigidity, and are extremely sensitive to weight, traditional vehicle chassis often choose a design with higher weight to ensure driving comfort and reliability. Topological fusion of frame structure, using the main carbon fiber tube and aviation aluminum alloy connection, local aluminum alloy or alloy steel welding scheme, the original chassis functional components and cover parts are directly arranged on the frame. The upper position of the front rotor will block the driver's sight of land driving and air control, so it is placed at the bottom; the lower position of the rear rotor will affect the observation field of the driver's rearview mirror when driving on land, so it is placed at the top. Hence the design with the front rotor below and the rear rotor above. With the improvement of the country's requirements for energy saving and emission reduction, how to apply advanced structural design technology to the structural design of the frame to achieve weight reduction and light weight of the frame, so as to meet the increasingly stringent national regulations and improve lift, and become a future car key factor for plant survival.

In order to better realize the weight reduction task in the lightweight design, the overall design of the present invention abandons the traditional automobile chassis and flight frame, and designs a new flight-driving integrated frame structure. The new fusion frame adopts an integrated topology structure. The present invention is based on the conventional multi-rotor layout, the four-axis eight-propeller aircraft structure is used as the main flight structure, and the ground driving is in the form of Ackerman steering 7 and McPherson suspension shock absorption.

The frame uses carbon fiber tube as the frame, which is connected by aviation aluminum alloy. The original chassis functional components and cover parts are directly arranged on the frame. In addition, in order to facilitate the driver's observation of the surrounding environment and safe driving when driving on the ground, the layout of the flying motor power source adopts a non-square parallel and out-of-plane center-symmetric structure.

A topological fusion frame structure, including a sub-frame body, the frame structure is composed of 17 carbon fiber tubes 18 (which can be increased or decreased according to actual needs) on a chassis 8 in the form of McPherson suspension and shock absorption, and aviation aluminum alloys. 19 is connected in such a way that the pin is positioned and the bolt 20 is locked. It also includes some link points on the body to form a stable triangular reinforcing rib carbon fiber tube 21 structure, and the cross reinforcing rib structure is arranged on the front lower part of the frame body. The motor of the frame body is supported by the motor bracket and connected with the carbon fiber tube bolts. The frame takes into account the safety of vision during ground driving and flight, and the propellers of the four-axis and eight-propeller flying car are not set on the same plane, but the front propeller is designed to go down and the rear propeller to go up. The front propeller position is located under the front glass of the body due to the limited visibility of the driver. The rear part is located on the upper part of the body in consideration of the collision between the body and the car coming from behind.

Since the flying car considers the flight requirements, the roof adopts a transparent material acrylic panel roof window 11; due to the flight requirements, the side windows of the vehicle body are not limited to the left rear upper window 9 on the upper part, and the left front upper window 12, which is in the lower part. 17 of the left lower window and the right lower window (due to the angle of view, not marked in the picture) are also designed to make the driving experience better and safer.
