Specific examples

It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

As shown in FIG. 1, it shows a structural diagram of a flying car provided by an embodiment of the present invention. The flying car includes: a car body 10, a rotor assembly 20, a cruise assembly 30, a sensor assembly (not shown in the figure), Landing assembly 40 and control assembly (not shown in the figure); cruise assembly 30 includes: wing 301 and thrust fan 302; rotor assembly includes: multiple sets of ducted fans 201; wing 301 is provided on the top of the car body 10, thrust The fan 302 is provided at the top of the car body 10 at a position corresponding to the longitudinal center axis; the landing assembly 40 is provided at the bottom of the car body 10; multiple sets of ducted fans 201 are symmetrically distributed and arranged around the car body 10; the sensor assembly is used to monitor The driving status of the vehicle body 10 is sent to the control component; the control component is used to control the rotor component 20, the cruise component 30, and the landing component 40 to work according to the driving status.

In the embodiment of the present invention, the flying car can realize the vertical take-off and landing through the cooperation of the rotor assembly 20 and the landing assembly 40, to meet the requirements of the vertical take-off and vertical landing of the flying car in multiple scenarios, and to get rid of the flying car in the existing technical solutions The problem is that the runway needs to be assisted to take off and land, and in the flight state, the horizontal assembly of the flying car can be achieved through the cruise assembly 30, which greatly improves the cruising efficiency and endurance of the flying car.

The car body 10 is consistent with the current car body, and the power drive when driving on the road surface can be a front drive type, a rear drive type, or a four-wheel drive type. In addition, the car body 10 can also use the thrust fan 302 of the cruise assembly 30, To realize the thrust driving on the road surface, the embodiment of the present invention takes the thrust fan 302 as the driving device of the flying automobile on the ground as an example to describe the flying automobile.

Specifically, the overall structure of the car body 10 may be a streamlined structure to reduce wind resistance. The car body 10 includes: a top, a bottom, and a front cockpit 101 and a rear portion, which defines the longitudinal axis direction of the car body 10 along the length of the vehicle body, parallel For the main direction of movement of flying cars, the front cockpit 101 can be designed to carry at least two people. Further, the car body 10 can be made of lightweight materials (for example: carbon fiber materials) to reduce the car as much as possible while ensuring safety Body mass, improve the endurance of flying cars.

Optionally, the number of ducted fans is an integer multiple of 4.

In the embodiment of the present invention, referring to FIG. 2, which shows a top view of a flying car provided by an embodiment of the present invention, the rotor assembly 20 is mainly used to realize the vertical take-off and landing function of the flying car, including multiple sets of culverts Fan 201, ducted fan 201 is a device that provides vertical take-off and landing lift for flying cars. The ducted axis of ducted fan 201 is parallel to the vertical direction and is used to provide vertical lift. For safety reasons, at least 4 sets of ducts can be used Fan 201, in special cases, the number of ducted fans 201 can be increased to an integer multiple of 4, (8 groups of ducted fans 201 are used in FIG. 2), 8 groups of ducted fans 201 are evenly distributed in the car The surroundings of the body 10 provide lift for the vehicle body 10 to take off and land vertically or assist the vehicle body 10 in posture adjustment. During the operation of the ducted fan 201, its incoming flow speed is small, and its rotor blades can be used with fixed pitch blades suitable for low incoming flow speed. The thrust is controlled by the rotation speed. The rotor blade can be controlled by an electric motor (not shown in the drawings) ) Direct drive.

Further, multiple groups of ducted fans 201 may be distributed in a rectangular shape. Along the wingspan of the wing 301, the ducted fans 201 on both sides of the car body 10 are symmetrical with respect to the longitudinal symmetry plane A of the car body 10; along the length of the car body 10, the front and rear ducted fans 201 of the car body 10 are relative to the lateral direction The vertical section B is symmetrical. Among them, the longitudinal symmetry plane A and the transverse vertical tangent plane B perpendicularly intersect, and the intersection line is generally close to or passes through the center of gravity of the automobile body 10 and the lift center of the wing 301.

It should be noted that according to the road vehicle driving standards, the width of the car should not exceed 2.5 meters. Therefore, in order to ensure that the flying car has a certain width near the ground and the ground state, increase the number of ducted fans 201 and use a smaller size The duct fan 201 may increase the lateral wheelbase of the lift points on both sides of the flying car, which will be more advantageous for the attitude adjustment of the flying car. Therefore, 8 groups of ducted fans 201 are adopted as the preferred solution.

Compared with large variable pitch blades with high power and low speed, electric motors are very suitable for driving such distributed small-size, high-speed rotors or fans. Compared with the direct drive method of internal combustion engine rotors, electric motor drives have light weight, The advantages of small size and fast response speed, followed by the simple structure of the electric motor, fewer moving parts, and high reliability. In addition, the external culverts around the rotor can play a good role in protecting the rotor and its surroundings and improve the safety of the whole machine. The external culverts also have the advantages of adding extra lift and reducing noise.

The sensor module is used to send the monitored driving status of the flying car to the control module. The control module is used to perform specific flight operations when it is determined that the flying car is in a different flying state according to the received driving status. What needs to be explained is The sensor module can also send the monitored data to the IoV server via a wireless network, and the IoV server can further plan the flight operation of the flying car based on the data and feed the result back to the control module of the flying car.

Further, referring to FIG. 2, the wing 301 is located at the top of the car body 10, and its longitudinal position is related to the overall center of gravity of the flying car. In the horizontal flight state, the lateral axis of the flying car is defined along the direction of the wingspan of the wing 301. The outer side of the trailing edge of the wing 301 can be provided with a movable aileron 3011 that can control the rolling maneuver of the flying car. According to requirements, in other embodiments, the wing 301 can add other maneuvers for optimizing aerodynamic performance, such as increase in lift and drag reduction. Faces such as flaps, wingtips, winglets and other devices.

In the embodiment of the present invention, the thrust fan 302 is a device that provides forward thrust for a flying car, and may be similar to the structure of the ducted fan 201. Preferably, two sets of thrust fans 302 may be symmetrically arranged. The longitudinal symmetry plane A of the automobile body 10 is symmetrical, and the thrust fan 302 does not produce airflow influence with the ducted fan 201 during operation. The thrust fan 302 and the wing 301 can be installed independently of each other, without affecting the spread of the wing 301. In view of the characteristics that the incoming speed of the thrust fan 302 changes greatly during operation and the incoming speed is high during cruising, the rotor of the thrust fan 302 uses variable pitch blades to keep it relatively constant at different incoming speeds High propulsion efficiency. In addition, through the variable pitch adjustment, the rotor can generate reverse thrust, which increases the dynamics of the flying plane. Also, because the working environment of the ducted fan 201 and the thrust fan 302 is different, the design of the external duct will also be different.

Taking rotation speed control as an example, the thickness of the turning arrow represents the speed of the bypass fan 201.

Specifically, when the sensor assembly detects that the driving state of the vehicle body is the vertical landing state b, the control assembly controls the rotational speed of all the ducted fans 201 to be less than the first preset rotational speed, and controls the landing bracket 401 to protrude from the storage tank.

Optionally, when the sensor assembly detects that the driving state of the automobile body is a vertically ascending state, the control assembly controls the rotation speed of all the bypass fans to be greater than a sixth preset rotation speed.

In a specific example, when the flying car is in the hovering state a, the rotational speed of the ducted fan 201 is the first preset speed. When the flying car changes from the hovering state a to the vertical landing state b, it needs to be reduced by 8 at the same time. Set the speed of the ducted fan 201 to reduce the overall lift, so that the speed of the ducted fan 201 is less than the first preset speed; in addition, when the flying car wants to enter the vertical climbing state c, you need to increase 8 sets of ducted fans at the same time The rotation speed of 201 increases the overall lift, so that the rotation speed of the bypass fan is greater than the sixth preset rotation speed, where the sixth preset rotation speed is greater than or equal to the first preset rotation speed.

In a specific example, when the flying car wants to do a roll maneuver d to the left and keep the flying height constant (the total vertical lift is unchanged), it is necessary to increase the rotation speed of the bypass fan 201 on the right side of the car body 10 at the same time. Increasing the right side lift force, and at the same time reducing the rotation speed of the left bypass duct 201 of the vehicle body 10 to reduce the left side lift force, and at the same time, it is necessary to maintain the total lift force of the vehicle body 10 in the vertical direction unchanged. Correspondingly, when the flying car wants to roll the maneuver e to the right and keep the flying height unchanged, it is necessary to increase the speed of the bypass fan 201 on the left side of the car body 10 at the same time to increase the left lift and reduce the car at the same time The rotation speed of the bypass duct 201 on the right side of the main body 10 is used to reduce the right lift, and at the same time, the total lift in the vertical direction of the main body 10 of the vehicle needs to be maintained unchanged.

Taking the speed control as an example, the thickness of the turning arrow represents the speed of the bypass fan 201.

When the flying car wants to make a counterclockwise yaw state h around its center and keep the flying height unchanged, it is necessary to increase the speed of the bypass fan 201 of the car body 10 rotating clockwise at the same time, and at the same time reduce the counterclockwise rotation of the car body 10 The rotation speed of the ducted fan 201 causes the automobile body 10 as a whole to withstand a counterclockwise rotation torque, and at the same time, it is necessary to maintain the total lift of the automobile body 10 in the vertical direction unchanged. Correspondingly, when the flying car wants to make a clockwise yaw state i around its center and keep the flying height unchanged, it is necessary to increase the speed of the bypass fan 201 of the car body 10 rotating counterclockwise at the same time, and at the same time reduce the car body The rotational speed of the ducted fan 201 rotating clockwise 10 makes the whole body 10 of the vehicle bear a clockwise rotation torque, and at the same time needs to maintain the total lift of the body 10 in the vertical direction unchanged.

Based on the above description of the flying vehicle in the clockwise / counterclockwise yaw state, it should be noted that in one case, the fourth preset speed and the fifth preset speed may be the same speed, that is, assuming the fourth preset speed and The fifth preset speed is 10000 rpm, when the flying car needs to rotate slightly counterclockwise, the speed of the bypass fan rotating clockwise can be controlled to be greater than 10000 rpm, and the bypass that rotates counterclockwise can be controlled The speed of the fan is less than 10,000 rpm.

The flying car mainly includes four main states: ground static state j, wing retracted hover state k, and wing expansion. Hover state l and steady cruise state m.

Specifically, the take-off process n can be changed from the ground static state j to the wing retracted hover state k. At this time, the lift and maneuver of vertical flight are completely completed by the rotor assembly. After the flying car passes through the wing deployment process p, the wing retracted hover state k can be changed to the wing deployed hover state l, preparing for the vertical / level flight mode switching. Through the action of the thrust fan 302, the flying car can further pass an acceleration process r to complete the change from the wing deployment hover state l to the stable cruise state m.
