Abstract

This invention discloses a distributed, reusable power flying car, comprising: a vehicle body, vehicle wheel rims and wheel systems, and a hub motor-cycloidal propeller integrated mechanism. The flying car's flight is powered by four hub motors driving cycloidal propellers, and its ground driving is also powered by four hub motors driving the wheels. The hub motor-cycloidal propeller integrated mechanism can control the magnitude and direction of power transmission; that is, it can transmit power to the cycloidal propellers when the car is in flight mode, and to the wheels when the car is in ground driving mode, thus achieving reusable power. This invention places the cycloidal propeller mechanism inside the wheels, saving external space and facilitating faster switching between ground driving and flight modes. Furthermore, the flight structure of this invention is a cycloidal propeller design, rotating in the same direction as the wheels. Various flight attitudes can be achieved by adjusting the aerodynamic forces of the cycloidal propellers through the hub motors.

Description

Technical Field

[0001] This invention relates to the field of flying cars, and more specifically to a flying car that uses a single power system for both flight and ground driving. Background Technology

[0002] Traditional transportation relies primarily on road traffic. However, in recent years, with the increasing severity of congestion and traffic accidents, flying cars, capable of freely switching between land and air travel, have become a significant research area. The design of flying cars has been limited by their complex structures and limited testing space, hindering their development. However, with the advancement of modern automotive electrification and intelligentization, flying car design has made considerable progress and has become a research hotspot in recent years. Flying cars will usher in a new era of low-altitude logistics and intelligent transportation, representing an inevitable development following automotive electrification and intelligentization, and a future industry with a comprehensive driving force and significant impact on the economy and society.

[0003] Existing flying car designs, in terms of layout, are mainly divided into two types: propeller-driven flying cars and electric vertical take-off and landing flying cars.

[0004] Propeller-mounted flying cars place propellers around the vehicle, controlling their aerodynamic characteristics to achieve flight similar to aircraft. The car chassis is located underneath, enabling ground-based driving. However, this design results in large propeller footprints, compromising stability and safety on the ground and potentially obstructing other vehicles. Furthermore, the need for a separate propeller power unit for flight capabilities increases the car's mass and size, leading to excessively large vehicles that are detrimental to both drivability and energy efficiency.

[0005] Electric vertical takeoff and landing (eVTOL) flying cars are single-seat vehicles, which limits their load-bearing capacity. This design places the propellers directly above the vehicle to achieve vertical takeoff and landing capabilities similar to helicopters. However, considering the vehicle's size and the limited lift provided by the propellers, a chassis system cannot be properly installed below the cockpit. This prevents true switching between ground driving and flight, thus placing it within the category of an aircraft; the vehicle's driving function cannot be fully realized.

[0006] To address the problems inherent in the two aforementioned flying car designs, this invention achieves flight capability through a cycloidal propeller-type flight structure. The cycloidal propeller aircraft can control the aerodynamic forces of each propeller blade to achieve forward, backward, ascent, and descent functions. Considering the similarity between the arrangement and motion of the cycloidal propellers in the aircraft and the wheels of a car, this invention combines the two, using a single power system to perform both ground driving and flight functions. This achieves power reuse capability, saves space in the car's layout, improves the car's driving economy, and reduces the load during flight while maintaining normal ground driving capabilities. This technical solution has the potential for application in high-end electric four-wheel drive vehicles and possesses significant economic and social value. Summary of the Invention

[0007] The purpose of this invention is to propose a single-power-source flying car solution that uses a single power system for both flight and driving. This solution connects the car's flight mechanism assembly and wheel assemblies via a single power unit, and uses the power system to separately control the power for flight and ground driving. It switches between different power output directions under different operating conditions, thus achieving arbitrary switching between the two modes. This design aims to solve the problems of power configuration redundancy and increased weight and cost caused by existing inventions that require two power systems to complete two application scenarios. It also extends the flight and driving range of flying cars, better addressing urban traffic congestion. The flying car of this invention uses a cycloidal propeller-type flight mechanism as its flight device and a four-wheel independent drive system as its driving mechanism. Switching between flight and ground driving modes is achieved by controlling the power mechanism.

[0008] When the distributed multiplexed power electric four-wheel drive flying car is operating in ground driving mode, the driving torque output by the hub motor is fully distributed to the wheels through the suspension wheel-side mechanism. The car's cycloidal propeller is stationary, and the car can perform ground driving functions. Since the present invention places the cycloidal propeller mechanism between the car body and the wheels, the car will not affect the driving of other vehicles due to the excessive size of the flying device when driving on the ground, and can ensure a certain degree of maneuverability, handling stability and power.

[0009] When the distributed multiplexed power electric four-wheel drive flying car operates in flight mode, the hub motor controls the deployment of the cycloidal propeller wing section. At this time, the driving torque output by the hub motor is fully distributed to the cycloidal propeller blades. By controlling the aerodynamic force of the cycloidal propeller, the car can achieve vertical takeoff and landing and fly in three-dimensional space. The car wheels are stationary during this time, which does not affect the car's normal flight. Since the maximum wheel speed required for the car to travel on the ground is higher than the speed required by the cycloidal propeller flight mechanism during flight, and the maximum torque obtainable from the wheels is greater than the maximum torque required by the cycloidal propeller flight mechanism during flight, the hub motor of this invention fully meets the speed and torque requirements for flight mode operation. No additional transmission device is needed, improving the car's energy utilization rate and enabling the car to better perform its flight functions.

[0010] To achieve the above objectives, the technical solution of the present invention is as follows:

[0011] A distributed, multiplexed, electric four-wheel-drive flying car, characterized in that it comprises:

[0012] The power integration and switching mechanism can switch the power output direction of the two power output shafts between the cycloidal propeller and the wheel, and drive the rotation of the car wheel and the cycloidal propeller flight mechanism.

[0013] The cycloidal propeller flight mechanism is a system that performs flight functions. Four propeller blades are equidistantly mounted on a rotating base on the wing to replace the traditional propeller-type flight mechanism of flying cars. Based on the working characteristics of the cycloidal propeller mechanism, the flying car can realize actions such as lifting, moving forward and hovering.

[0014] The hub motor cycloidal propeller integrated mechanism enables the flying car to perform flight functions. The distributed multiplexed power electric four-wheel drive flying car of the present invention integrates the hub motor cycloidal propeller integrated mechanism between the hub and the body. This can significantly reduce the space occupied by the cycloidal propeller in the ground driving mode and improve the utilization rate of the space inside the hub.

[0015] The hub motor cycloidal propeller integrated mechanism includes a power integration and switching mechanism and a cycloidal propeller flight mechanism. The power integration and switching mechanism and the cycloidal propeller flight mechanism are connected by a spline. The power integration and switching mechanism provides power and enables the switching of power direction, while the cycloidal propeller flight mechanism provides the lift required for vehicle flight.

[0016] The power integration and switching mechanism includes a hub motor, two power output shafts, and a motor wiring harness. The two power output shafts are mounted on both ends of the hub motor, and the motor wiring harness is fixed on the housing of the hub motor to supply power to the hub motor. The hub motor provides power to the vehicle and outputs power to the vehicle wheels and the cycloidal propeller engagement base in the two modes of the vehicle, respectively.

[0017] The cycloidal propeller flight mechanism includes a cycloidal propeller mounting base, a cycloidal propeller, a cycloidal propeller fixing screw, a cycloidal propeller angle adjusting gear, a cycloidal propeller rotating screw, and a positioning gear. The cycloidal propeller is assembled with the cycloidal propeller fixing screw and the cycloidal propeller rotating screw through mounting holes on the cycloidal propeller. The other end of the cycloidal propeller rotating screw is eccentrically connected to the positioning gear through a mounting hole in the cycloidal propeller mounting base. The other end of the cycloidal propeller fixing screw is connected to the center position of the positioning gear through a mounting hole in the cycloidal propeller mounting base. The positioning gear meshes with the cycloidal propeller angle adjusting gear, and the end cap protects and fixes the gear.

[0018] A distributed, reused power electric four-wheel drive flying car, characterized in that it includes:

[0019] The distributed, multi-powered, electric four-wheel-drive flying car has a flight mode and a ground driving mode. Switching between the two modes is achieved by controlling the power integration and switching mechanism.

[0020] The power integration and switching mechanism has a disconnected state, a flight power output state, and a ground driving power output state. By controlling the internal electromechanical control system, the disconnected state, the flight power output state, and the ground driving power output state can be controlled, and the power integration and switching mechanism can switch between the three working states.

[0021] When the distributed multiplexed power electric four-wheel drive flying car is in ground driving mode, the power output shafts at both ends transmit power to the wheels, thereby realizing ground driving mode.

[0022] When the distributed multiplexed power electric four-wheel drive flying car operates in flight mode, the power of the hub motors controls the engagement of the power integration and switching mechanism and the second output direction of the two-end power output shafts. Power is transmitted from the hub motors through the power integration and switching mechanism to the second output direction of the two-end power output shafts. The output shafts are connected to the cycloidal propeller flight mechanism, ultimately transmitting power to the cycloidal propeller mounting base. Utilizing the power transmitted from the two-end power output shafts, the cycloidal propeller can change its angle under the control of the cycloidal propeller mounting base and the cycloidal propeller rotating screw, thereby altering the aerodynamic forces and completing flight maneuvers.

[0023] When the distributed multiplexed power electric four-wheel drive flying car is in flight mode, the cycloidal propeller extends out of the vehicle body at a certain angle under the control of the power integration and switching mechanism. The cycloidal propeller rotates using the power transmitted from the power output shafts at both ends, driving the car to fly.

[0024] The beneficial effects of this invention are:

[0025] 1. The distributed multiplexing power electric four-wheel drive flying car of the present invention integrates the cycloidal propeller flight mechanism between the car wheel hub and the car body, which greatly reduces the driving space occupied by the flight mechanism when the car is in ground driving mode, improves the space utilization rate of the flying car, and has a high degree of integration and modularity.

[0026] 2. The distributed multiplexing power electric four-wheel drive flying car of the present invention uses a cycloidal propeller as the car's flight mechanism. It is small in size and its working mode is similar to that of the wheels. Placing it between the car body and the wheel hub also reduces other safety hazards caused by exposed wings, making its working environment safer and more reliable.

[0027] 3. The distributed multiplexing power electric four-wheel drive flying car of the present invention utilizes a power integration and switching mechanism to move the output shaft axially, enabling power switching between two modes: ground driving and flight. By utilizing the power integration and switching mechanism, one power source meets two usage requirements, saving power and achieving better economy.

[0028] 4. The distributed multiplexing power electric four-wheel drive flying car of the present invention can control the switching between two modes with only one control mechanism, with fewer control actuators, simplified structure and reliable control.

[0029] 5. The distributed multiplexing power electric four-wheel drive flying car of the present invention integrates the cycloidal propeller flight mechanism between the wheel hub and the car body, fully considering the possible mutual interference between the two modes. The integrated design enables the two modes to work independently without affecting each other. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0042] An embodiment of the present invention is given below with reference to the accompanying drawings.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, this embodiment provides a distributed, multiplexed power electric four-wheel-drive flying car, including a flying car body and its power mechanism. The flying car body includes a body 1, a support axle 2, wheel rims and wheel systems 3, a hub motor cycloidal propeller integrated mechanism 4, and a suspension system 5. The body 1 is supported by the support axle 2 at the front and rear. The wheel rims and wheel systems 3 and the hub motor cycloidal propeller integrated mechanism 4 are symmetrically mounted at both ends of the support axle 2. The hub motor cycloidal propeller integrated mechanism 4 is connected to the wheel rims and wheel systems 3 through the support axle 2, thereby enabling power transmission and realizing the respective functions of the two systems.

[0044] The wheel and wheel system 3 includes a car wheel 6 and a suspension wheel mechanism 7. The car wheel 5 and the suspension wheel mechanism 7 are connected to the hub motor cycloidal propeller integration mechanism 4 via a support shaft 2. The wheel and wheel system 3 performs the function of ground driving for the flying car.

[0045] The hub motor cycloidal propeller integration mechanism 4 includes a power integration and switching mechanism 8 and a cycloidal propeller flight mechanism 9; the power integration and switching mechanism 8 and the cycloidal propeller flight mechanism 9 are connected by a spline, the power integration and switching mechanism 8 provides power and realizes the switching of power direction, and the cycloidal propeller flight mechanism 9 provides the lift required for the car to fly.

[0046] The power integration and switching mechanism 8 is connected to the cycloidal propeller fixing screw 16 and the cycloidal propeller rotating screw 18 on the cycloidal propeller mounting base 10. The angle of the cycloidal propeller 15 is controlled by controlling the cycloidal propeller rotating screw 18. The cycloidal propeller 15 is assembled with the cycloidal propeller fixing screw 16 and the cycloidal propeller rotating screw 18. The power output shafts 13 at both ends are connected to the power integration and switching mechanism 8 and the cycloidal propeller mounting base 10 to output power.

[0047] Example 2

[0048] like Figure 5 , 6 As shown in Figures 7 and 8, this embodiment provides a distributed multiplexed power electric four-wheel drive flying car, which has a flight mode and a ground driving mode. The switching between the two modes is achieved by controlling the power integration and switching mechanism.

[0049] When the distributed multiplexed power electric four-wheel drive flying car is operating in ground driving mode, the driving torque output by the hub motor is fully distributed to the wheels through the wheel-side mechanism. The cycloidal propeller of the flying car is stationary, and the car can perform ground driving functions.

[0050] When the distributed multiplexed power electric four-wheel drive flying car is operating in flight mode, the hub motor controls the deployment of the cycloidal propeller wing section and controls the engagement of the power integration and switching mechanism and the second output direction of the two power output shafts. At this time, the driving torque output by the hub motor is fully distributed to the cycloidal propeller wing section. Power is transmitted from the hub motor through the power integration and switching mechanism to the second output direction of the two power output shafts. At this time, the two power output shafts are connected to the cycloidal propeller flight mechanism, and finally the power is transmitted to the cycloidal propeller mounting base. Using the power transmitted by the two power output shafts, the two power output shafts of the cycloidal propeller can change their angle under the control of the cycloidal propeller mounting base and the cycloidal propeller rotating screw, thereby changing the aerodynamic force and completing the flight action. By controlling the aerodynamic force of the cycloidal propeller, the car can achieve vertical take-off and landing and fly in three-dimensional space. At this time, the car wheels are stationary and will not affect the normal flight of the car.

They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and examples shown herein.
