[0002] With the continuous increase in the number of motor vehicles, urban transportation systems are facing increasingly severe challenges such as congestion, traffic disorder, and frequent traffic accidents. Traditional ground-based transportation modes can no longer meet the growing and diverse travel demands of densely populated cities, prompting a transformation of transportation systems towards an integrated air-ground system. Against this backdrop, flying cars, as an innovative mode of transportation that combines the characteristics of aviation and ground transportation, are gradually moving from conceptual design to engineering realization, demonstrating enormous technological development potential and application prospects. Quadrotor vertical takeoff and landing flying cars, due to their advantages such as no runway required for takeoff and landing, flexible handling, and strong environmental adaptability, are widely regarded as an ideal solution for urban low-altitude transportation and short-distance air travel.

[0003] Existing flying cars have the following problems: they are heavy, have limited range and flight efficiency, and lack structural strength, fatigue life, corrosion resistance and configuration flexibility, making them unsuitable for vertical take-off and landing design and prototype manufacturing. Summary of the Invention

[0004] This application aims to at least solve the technical problem that existing flying cars are not suitable for vertical take-off and landing design and trial production. To this end, this application provides a flying car that is easy to adjust and improve in the trial production process, and can successfully perform vertical take-off and landing and flight.

Detailed Implementation

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application. The described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments in this application, they can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] This application is described below with reference to the accompanying drawings and specific embodiments:

[0028] Referring to Figure 1, this embodiment of the application provides a flying car 100, which includes: an aircraft 110, a connecting part 120, and a vehicle chassis 130. In use, from top to bottom, the components are the aircraft 110, the connecting part 120, and the vehicle chassis 130. The aircraft 110 includes a frame 111, a control component 112, multiple flight drive components 113, and multiple propellers 114. The number of flight drive components 113 and propellers 114 can be determined as needed and are one-to-one. The propellers 114 are conventional propellers, providing lift for the flying car 100 during flight. The control component 112 and the multiple flight drive components 113 are respectively mounted on the frame 111. The control component 112 is electrically connected to the multiple flight drive components 113 and is used to control each flight drive component 113. The propeller 114 is correspondingly mounted on the output end of the flight drive assembly 113 and is driven by the flight drive assembly 113. The connecting part 120 is detachably connected to the frame 111 or the control assembly 112. For example, one end of the connecting part 120 is connected to the frame 111 or the vehicle chassis 130 by screws or bolts. The vehicle chassis 130 includes a floor plate 131 and multiple wheels 132 mounted on the floor plate 131. The wheels 132 are connected to the floor plate 131 by conventional assembly. The floor plate 131 adopts a plate structure that can bear a certain load as the bottom structure of the car. The floor plate 131 is detachably connected to the connecting part 120. For example, the other end of the connecting part 120 is connected to the floor plate 131 by screws or bolts. For this application, a power supply 150 is also required. If the power supply 150 is a lithium battery, it is fixed on the base plate 131. The power supply 150 supplies power to the control component 112 and the flight drive component 113 mentioned above, and provides power to the flying car 100.

[0029] Existing flying cars are unsuitable for vertical takeoff and landing (VTOL) design and prototyping. This is because the design and prototyping of VTOL flying cars require timely adjustments to the structure and hardware / software to facilitate prototype improvements. However, most current flying cars are not designed for easy adjustment. This application enables successful VTOL takeoff and landing and controlled flight. Multiple flight drive components 113 independently drive multiple propellers 114, and a control component 112 controls the flight drive components 113. A connecting part 120 detachably connects the aircraft 110 and the vehicle chassis 130, providing high configuration flexibility. This facilitates design adjustments and improvements during prototyping, enabling successful VTOL takeoff and landing and flight. It provides strong support for the research and verification of key flying car technologies, significantly promoting the development of next-generation integrated air-ground transportation vehicles, and has significant engineering application value and cutting-edge demonstration significance. Furthermore, the detachable connection structure allows for partial redesign or improvement of the flying car 100, further facilitating design and prototyping.

[0030] In some embodiments, the vehicle chassis 130 further includes a driving steering assembly 133 and a driving drive assembly 134. The driving steering assembly 133 is connected to the wheel 132, and the output end of the driving drive assembly 134 is connected to the wheel hub of the wheel 132. The wheel 132 is made of rubber and provides power for the flying car 100 to travel on the road. Both the driving steering assembly 133 and the driving drive assembly 134 are fixed to the base plate 131, which is made of carbon fiber. The driving steering assembly 133 and the driving drive assembly 134 are powered by a power supply 150. The driving steering assembly can be a motor with a belt drive structure or other steering structure. The driving steering assembly 133 is used for steering the car, and the driving drive assembly 134 is a direct-drive motor or other device that can drive the wheel 132. The driving drive assembly 134 is used for driving the car, and the driving drive assembly 134 enables the flying car 100 to travel on the road.

[0031] Referring to Figure 2, in some embodiments, the driving steering assembly 133 includes an angle adjuster 1331 and multiple gears. The angle adjuster 1331 is mounted on the base plate 131 and powered by a power supply 150. The output end of the angle adjuster 1331 is connected to one gear, and at least part of the other gears are fixed relative to the driving drive assembly 134, with adjacent gears being connected by transmission. Through the cooperation of the angle adjuster 1331 and the gears, the road steering function of the flying car 100 can be realized. In some embodiments, the multiple gears are divided into a main gear 1332 and two driven gears 1333. The two driven gears 1333 are respectively meshed on both sides of the main gear 1332, and the gear ratio between the main gear 1332 and the driven gears 1333 is [1.2, 1.5], such as 1.2, 1, 3, or 1.5.

[0032] In some embodiments, the driving assembly 134 includes a second driver 1341 and a bracket 1342. The bracket 1342 is fixed relative to the driven gear 1333. The second driver 1341 is mounted on the bracket 1342, and the output end of the second driver 1341 is connected to the hub of the wheel 132. The second driver 1341 is used to drive the wheel 132, and the bracket 1342 is used to facilitate the installation of the second driver 1341. The second driver 1341 is a motor, the bracket 1342 is a motor mount, and the angle adjuster 1331 is a servo motor. The main gear 1332 is fixed to the output end of the servo motor. There are two driven gears 1333, which mesh with the two sides of the main gear 1332 to form a gear set. The driven gears 1333 are fixed relative to the bracket 1342 and can rotate together relative to the base plate 131 at a certain angle.

[0033] In some implementations, a servo-driven gear set is used to steer the front wheels. The core of this scheme is a three-stage transmission structure: Power input stage: An SG90 servo is vertically fixed to the base plate 131, and its output shaft is rigidly connected to a 27-tooth steering master gear 1332 via bolts. Motion conversion stage: A driven gear 1333 set with 20 meshing teeth on both sides of the master gear 1332, with a gear ratio set to 27:20, ensures that a 60.75° servo rotation angle is mapped to an actual 45° rotation angle of the wheel 132. Force transmission stage: A fixed steering arm extends radially from the driven gear 1333 and is hinged to the steering tie rod system via a connector, ultimately driving the front wheels to rotate around the kingpin axis.

[0034] In some implementations, a dual-motor rear-drive architecture is adopted: the power system uses a distributed hub motor drive scheme, with each of the two rear wheels equipped with a 600W brushless motor, rigidly connected to the wheel hub via motor brackets 1342 and screws, achieving linear control of the speed range from 0-50000 RPM. The power battery is a 75A battery pack with 4 rotor stages, which, after voltage regulation, independently powers the two motors, with a maximum output power of 1200W.

[0035] Referring to Figure 3, in some embodiments, there are four flight drive components 113 and four rotor blades 114, which are symmetrically and spaced apart from the frame 111, arranged in a four-corner distribution. The drive torque directions of the flight drive components 113 located on the diagonals are the same, and the drive torque directions of the flight drive components 113 located on the two diagonals are opposite. The four flight drive components 113 and the rotor blades 114 form a quadcopter, and the lift generated enables the flying car 100 to achieve vertical take-off and landing and flight. The control component 112 is connected to the four flight drive components 113, which can drive the four flight drive components 113 synchronously. By utilizing the direction and magnitude of the drive torque of each diagonal flight drive component 113, the flying car 100 can achieve flight and flight steering functions.

[0036] In some embodiments, the flight drive assembly 113 includes a first driver 1131 and an electronic speed controller. The electronic speed controller is electrically connected to the first driver 1131, and the output of the first driver 1131 is connected to the propeller blade 114. The first driver 1131 drives the propeller blade 114 to rotate, and the electronic speed controller controls the speed and rotation direction of the first driver 1131. In some embodiments, the control assembly 112 includes a flight controller 1121 and a circuit board 1122. The circuit board 1122 is electrically connected to the flight controller 1121, and the flight controller 1121 is electrically connected to the flight drive assembly 113. For example, the bottom of the intersection of the frame 111 is connected to the circuit board 1122 by bolts or screws, the bottom of the circuit board 1122 is connected to the end of the connecting part 120 by screws or bolts, and the top is connected to the frame 111. The flight controller 1121 receives commands and outputs control commands to the electronic speed controller.

[0037] In some embodiments, the flight controller 1121 is a conventional flight controller 1121, the circuit board 1122 is an existing circuit board 1122 equipped with a control chip, the first driver 1131 is a motor, the electronic speed controller is an electronic speed controller, the frame 111 is X-shaped, forming four symmetrical arms. The arms are long plates with cutouts for weight reduction. The ends of the arms are provided with motor mounting ports, and the electronic speed controllers and motors are mounted in the mounting ports. The different interfaces of the output end of the flight controller 1121 are respectively connected to the signal transmission lines of the four electronic speed controllers, while the input end is connected to the output end of the remote controller receiver through multiple terminal lines to provide control signals for the flight phase of the flying car 100. The frame 111 includes arms and cross nodes. Four arms are connected to the cross nodes. The main board is located at the cross nodes. The shaft is made of nylon and fiber. The circuit board 1122 is made of glass fiber. The conductive parts at its four corners are soldered to the input terminals of four ESCs (four ESCs are connected to four rotor motors, and two ESCs are connected to two wheel 132 motors). The output wires of the ESCs are connected to the matching motors. The cross nodes are connected to the connecting parts 120 by bolts through glass fiber. The end of the arm integrates an A2212 brushless self-locking motor to ensure that its continuous output maximum power is 330W, while achieving motor weight reduction. At this time, the motor weight is only 56g.

[0038] In some implementations, steering, takeoff and landing, and flight are controlled by the flight drive assembly 113 and the control assembly 112. Based on the differential torque vector distribution principle, the APM flight control parses the remote controller commands and generates four-motor control signals. Heading control: Diagonal motor groups (right front-left rear as one group, rotating clockwise; left front-right rear as one group, rotating counterclockwise) are driven by differentiated speeds, using anti-torsion to achieve yaw rate control. Propeller blade 114 rotation optimization: The right front / lower left motors are equipped with forward-rotating 9450 propellers (CCW, pitch 4.5), and the left front / right rear motors are equipped with reverse-rotating 9450 propellers (CW, pitch 4.5). A threaded self-tightening structure ensures that the propeller blades 114 lock into zero displacement at high speeds.

[0039] In some implementations, a distributed brushless motor direct-drive architecture is adopted. The power unit consists of four A2212KV980 brushless motors, paired with 20A ESCs, connected to the power distribution board via silicone cables. Energy distribution: A PDB-XT60 four-layer power distribution board (2oz copper thickness) is installed in the center of the fuselage, supporting 12V lithium battery input and integrating a protection module. The propeller blades are 9450 blades.

[0040] In some embodiments, multiple right-angle fasteners 140 are also included. Some right-angle fasteners 140 are connected to one end of the connecting part 120 and the base plate 131, while the remaining right-angle fasteners 140 are connected to the other end of the connecting part 120, the frame 111, or the control component 112. For example, in this application, eight right-angle fasteners 140 are connected to the top end of the connecting part 120, and eight right-angle fasteners 140 are connected to the bottom end of the connecting part 120. Then, the lower right-angle fasteners 140, together with bolts, connect the connecting part 120 to the base plate 131, and the upper right-angle fasteners 140, together with bolts, connect the connecting part 120 to the circuit board 1122. The right-angle fasteners 140 are L-shaped parts with two connecting surfaces, such as those for mating with the top of the base plate 131 and the side of the connecting part 120, respectively. The connecting surfaces are provided with bolt holes for easy bolting. The right-angle fasteners 140 are externally connected and fixed by bolts.

[0041] Referring to Figure 4, in some embodiments, the connecting portion 120 includes multiple composite plates 121. Each composite plate 121 has a slot, and the edges of the multiple composite plates 121 are joined together to form a column. The space surrounded by the multiple composite plates 121 is connected to the outside through the slot. As shown, the connecting portion 120 is composed of four composite plates 121 joined in a ring. Each composite plate 121 is made of composite material, and the joints are fixed by welding or screws to form a rigid connection, constituting a whole. Furthermore, the slot design and the hollow internal design formed by the composite plates 121 significantly reduce the weight of the flying car 100.

[0042] This application achieves efficient and accurate simulation of over 100 driving modes of flying cars through scientific synergy and precise connection between various components. Furthermore, it features a simple structure, convenient operation, and practical functions. Simultaneously, it significantly reduces the overall weight, improves range and flight efficiency, and demonstrates superior performance in structural strength, fatigue life, corrosion resistance, and configuration flexibility. This not only promotes the integration and optimization of the Flying Car 100 technology system but also provides solid technical support and a practical platform for building a green, efficient, and intelligent urban three-dimensional transportation network in the future.
