Description

TECHNICAL FIELD

[0001] The present application belongs to the field of flying cars, and particularly relates to a modular triphibian multifunctional flying car. BACKGROUND

[0002] Traditional flying cars have complex exposed components such as a vehicle body, a chassis, and wheels, which have large resistance and gravity, require large lift to overcome, and have low safety and reliability, low use efficiency, and problems in flying car performance, airworthiness certification, and air traffic management.

[0003] Due to various drawbacks of traditional flying cars and high requirements of the state for low-altitude economy, a multifunctional flying vehicle that can fly on sea, land, and air, is suitable for ground driving, vertical take-off and landing, air hovering / flat flying, underwater diving, and various environments is provided. SUMMARY

[0004] To solve the problems of traditional flying cars having complex exposed components, large resistance and gravity, low safety and reliability, and low use efficiency, the present application provides a modular triphibian multifunctional flying car, the wings of which are foldable, the lift rotors are concealable, the thrust rotors are deflectable, and the floats are water-filling and draining, which is suitable for sea, land, and air triphibian environments. In a first aspect, a modular triphibian multifunctional flying car is provided, which comprises: a ground vehicle 1, four wheels 2 symmetrically arranged on the lower part of the ground vehicle 1, a power system 10 and a communication and automatic driving control system 11 arranged inside the front part of the ground vehicle 1, a flight cabin 3 provided with a communication control system, four connecting clamping grooves 12 arranged on the floor of the ground vehicle 1, four electromagnetic spring buckles 13 arranged on the lower part of the flight cabin 3 corresponding to the positions of the four connecting clamping grooves 12 arranged on the floor of the ground vehicle 1, and the electromagnetic spring buckles 13 capable of being clamped in the connecting clamping grooves 12. An inner segment and an outer segment of each wing 4 are evenly divided into two segments, and hydraulic mechanisms 17, hinge connecting mechanisms 20, spring positioning pins 18, and positioning holes 19 are arranged on the end faces between the segments; when the hydraulic mechanisms 17 are opened and closed, the inner and outer segments can be folded or unfolded around the hinge connecting mechanisms 20, and after folding, the spring positioning pins 18 are inserted into the positioning holes 19. Ailerons 6 are arranged near the outer side of the trailing edge of the inner segment of the wing 4, wing slide rail mechanisms 21 are arranged on the upper and lower surfaces inside the outer segment of the wing 4, two duct lift rotors 5 are arranged at 0.35 times the chord length of the outer segment of the wing 4, a dihedral tail 8 is arranged on the upper part of the tail of the flight cabin 3, a deflection rudder 9 is arranged at the outer end of the trailing edge of the dihedral tail 8, and a duct deflection rotor 7 is arranged at 0.35 times the chord length of the outer end of the dihedral tail 8.

[0005] Furthermore, a float 16 is installed at the bottom and tail of the flight cabin 3, and a water injection valve 14 and a water drainage valve 15 are installed at the bottom and tail of the flight cabin 3. The float 16 is connected to both the water injection valve 14 and the water injection valve 15.

[0006] In ground driving mode, the communication control system on the flight cabin 3 controls the electromagnetic spring buckle 13 to engage in the connecting slot 12, and the ground vehicle 1 and the flight cabin 3 are combined into one unit. The communication control system controls the hydraulic mechanism 17 on the end face rib of each segment of the wing to perform the closing operation. The inner and outer segments fold around the hinge connection mechanism 20, and the wing is folded up to reduce space occupation. The modular amphibious multi-functional flying car drives under the control of the power system 10 and the communication and autopilot control system 11.

[0007] When a flight switching command is received (either the pilot makes a judgment, or the power system 10 and the communication and autopilot control system 11 detect and judge traffic congestion or emergency situations), the flight mode is entered. In flight mode, the communication control system controls the spring positioning pin 18 to disengage from the positioning hole 19 and controls the hydraulic mechanism 17 on the end face rib of each wing segment to perform the unfolding operation. The inner and outer segments unfold around the hinge connection mechanism 20, and the folding wing segments are unfolded to become a complete wing 4. The sliding rail mechanism 21 inside the outer wing moves the skin above and below the inner rotor of the wing 4 along the wing surface, exposing the lifting rotor 5 hidden inside the wing. The communication control system starts the lifting rotor 5 and simultaneously starts the ducted deflector rotor 7 on the oblique tail fin at the rear of the flight cabin, and controls the electromagnetic spring buckle 13 to disengage from the connecting slot 12. The lifting rotor 5 and the deflector rotor 7 on the oblique tail fin increase their rotation speed. The lifting rotor 5 generates vertical lift, and the deflector rotor 7 on the oblique tail fin generates an upward pull perpendicular to the plane of the oblique tail fin. Its vertical component provides lift. When the lift is sufficient to balance the gravity, the flight cabin 3 takes off, and the communication and autopilot control system 11 controls the ground vehicle 1 to park nearby. After the flight cabin 3 takes off, the deflector 7 on the oblique tail 8 deflects 90° around its mounting axis and becomes fixed, transforming into a thrust propeller and generating forward thrust. At this time, the wing 4 generates lift. As the speed of the flight cabin 3 increases, the lift of the wing increases, and the lift rotor 5 hidden inside the wing begins to unload lift. Through the sliding rail mechanism 21 inside the wing 4, the wing skin moves along the surface of the wing 4 and returns to the holes on the upper and lower surfaces of the lift rotor 5, sealing the surface of the wing 4 and shutting down the lift rotor 5. At this time, the complete and smooth wing 4 generates greater lift and reduces drag as the speed increases, and the overall lift-to-drag ratio of the aircraft reaches its optimal level. The flight cabin 3 will fly at a greater forward speed. The aileron 6 arranged at the tail of the inner section of the wing 4 and the deflector 9 at the tail of the oblique tail 8 provide aerodynamic forces for the balance and attitude change of the aircraft.

[0008] Underwater modes (such as those required for marine scientific research, submarine cable repair, or underwater exploration) are divided into surface gliding and underwater submersible navigation.

[0009] In water gliding mode, the flying car operates in the same way as after takeoff from Flight Cabin 3. It can approach the water surface and fly rapidly by skimming the surface like a ground effect vehicle, or glide on the water surface like a boat.

[0010] In underwater submersible mode, flight cabin 3 transitions from forward flight mode to hovering mode: the sliding rail mechanism 21 inside the outer end of wing 4 removes the wing skin of the outer end 4, exposing the ducted lift rotor 5. The communication control system activates the lift rotor 5, which generates a portion of the lift. The deflecting rotor 7 at the tail of the oblique tail 8 deflects 90° in the opposite direction around its mounting axis, generating a pull perpendicular to the plane of the oblique tail 8. Its vertical component provides a portion of the lift. Flight cabin 3 lands on the water surface in a hovering manner. Seawater is injected into the float 16 at the bottom of the flight cabin through the water injection valve 14 at the tail, increasing the gravity of flight cabin 3. When the gravity is greater than the buoyancy, flight... When cabin 3 sinks, the communication control system detects that cabin 3 has reached the designated depth and controls the deflector rotor 7 at the tail of the oblique tail 8 to deflect 90° around its mounting axis and fix it, generating forward thrust. The duct hole on the surface of wing 4 is closed by the slide rail mechanism 21 at the outer end of wing 4 and the lift rotor 5 is closed. The communication control system controls the deflector rotor 7 to adjust its speed to adapt to the underwater propeller environment, and cabin 3 conducts underwater navigation. When it is necessary to surface, the float 16 discharges seawater through the drain valve 15, and the weight of cabin 3 decreases. When the weight is less than the buoyancy, cabin 3 surfaces and approaches the water surface. Cabin 3 then performs water surface taxiing takeoff or vertical climb to take off.

[0011] When a command to switch from flight mode to ground driving mode is received, the deflector rotor 7 decelerates, the flight cabin 3 decelerates and descends and hovers, and searches for the nearest ground vehicle 1 through the network platform. After hovering and landing, the communication control system controls the electromagnetic spring latch 13 to engage in the connecting slot 12, and the ground vehicle 1 and the flight cabin 3 are combined into one unit. The communication control system controls the hydraulic mechanism 17 on the end face ribs of each wing segment to perform the closing operation, and the inner and outer segments fold around the hinge connection mechanism 20, folding the wing to reduce space occupation. The communication control system shuts down the ducted lift rotor 5 and the deflector rotor 7. The modular amphibious multi-functional flying car drives on the ground under the control of the power system 10 and the communication and autopilot control system 11.

[0012] Among them, the motor and control system are located in the middle of the lifting rotor 5, and the motor, deflection mechanism and control system are located in the middle of the deflecting rotor 7.

[0013] The beneficial effects of this invention are at least as follows: This invention adopts a modular approach, integrating a ground vehicle, foldable wings, a vertical lift device, a propulsion device, and a flight cabin into a single aircraft. Through the engagement / disengagement of the connection buckles between the ground vehicle and the flight cabin, the unfolding / retraction of the foldable wings, the opening / closing of the lift rotors hidden inside the wings, the deflection of the slanted ducted deflector rotors, and the conversion of the water injection / drainage function of the floats at the bottom of the flight cabin, a multi-functional amphibious flying car capable of ground travel, vertical takeoff and landing, hovering / level flight, and underwater navigation is formed.

[0014] This invention relates to a modular amphibious multi-functional flying car, which has advantages such as ground driving, vertical take-off and landing, aerial cruising, and underwater navigation, expanding the scope of automobile usage. Through the application of this aircraft technology, the efficiency of automobile use can be improved in a compact and efficient manner, while meeting the application needs of various aspects such as air commuting, intercity travel, emergency rescue, disaster relief, and deep-sea exploration.

Detailed Implementation

[0017] The features and illustrative embodiments of various aspects of the present invention will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details.

Well-known structures and techniques are not shown in the drawings and the following description to avoid unnecessarily obscuring the invention.

[0018] It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other, and the various embodiments can be referenced and cited from each other.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] This invention provides a modularly combinable, foldable wing, concealable lift rotor, deflectable thrust rotor, and floats that can be filled and drained, making it suitable for amphibious environments including sea, land, and air.

[0021] The modular amphibious multi-functional flying car provided by this invention employs modular technology to combine a ground vehicle and a flight cabin into a single flying car. By separating the vehicle chassis, the aircraft flies with less drag, improving flight efficiency. A hydraulic mechanism allows the wings to be folded and retracted in sections for easy travel on ordinary roads. A sliding rail mechanism allows the wing skin to be removed to expose the front ducted lift rotor. The flight cabin and ground vehicle are connected / disconnected via a combination connector. The flight cabin can then take off and land vertically, the wings close via the sliding rails, the hidden front ducted lift fan is shut off, and the deflector rotor of the rear tail fin deflects 90° around its mounting axis to generate forward thrust, enabling forward flight. When navigating underwater, a water injection valve injects seawater into the buoys. While submerged, the speed of the rear rotor is adjusted to generate forward thrust in the water, enabling operation in amphibious environments.

[0022] This invention provides a modular amphibious multi-functional flying car, the details of which are as follows: (1) Ground driving mode, ground vehicle 1 (see Figure 2 ) and Flight Cabin 3 (see Figure 3 ) is connected by the middle combination buckle 12 (see Figure 4 The components are combined into one unit, with the wings folding down to reduce space usage. See [link / reference]. Figure 9 The ground vehicles possess standardized and independent power systems 10 and communication and automatic driving control systems 11, see [link / reference]. Figure 2 The network platform enables sharing functionality and can operate on ordinary highways; see [link / reference]. Figure 9 .

[0023] (2) In-flight mode: Upon receiving a flight switching command (either the pilot makes a judgment, or the power system 10 and communication and autopilot control system 11 detect and judge traffic congestion or emergency situations), see [link to relevant documentation]. Figure 2 Upon entering flight mode, the communication control system controls the spring positioning pin 18 to disengage from the positioning hole 19, thereby controlling the hydraulic mechanism 17 on the end face ribs of each wing segment to perform the deployment operation. The inner and outer segments unfold around the hinge connection mechanism 20. (See also...) Figure 5 After unfolding the folded wing sections, it becomes a complete wing 4. (See also...) Figure 1 .

[0024] (3) The slide rail mechanism 21 inside the outer wing consists of a lead screw actuator 22, a connecting rod 23, a slider 24, and a slide rail 25. The slider 24 is connected to the movable skin 26 on the wing 4, and the slide rail 25 is fixed to the wing 4. The lead screw actuator 22 is controlled to move axially through the communication control system. The connecting rod 23 connected to the lead screw actuator moves the slider 24 along the slide rail 25. The movable skin 26 moves along the slide rail 25 with the slider. See [link to relevant documentation] Figure 6 Wing 4, internal lift rotor 5 (see Figure 7 The movable skins on the upper and lower parts of the wing surface are moved away, revealing and activating the lift rotor 5 hidden inside the wing 4. At the same time, the obliquely mounted ducted deflector rotor 7 at the tail of the flight cabin 3 (see...) Figure 8 Upon activation, the ground vehicle 1 and the flight cabin 3 separate via the intermediate connecting clip. The lifting rotor 5 and the inclined ducted deflector rotor 7 increase their rotational speed. The lifting rotor 5 generates vertical lift, and the deflector rotor 7 generates a pull force perpendicular to the plane of the inclined duct, with its vertical component providing lift. When the lift is sufficient to balance gravity, the flight cabin 3 lifts vertically into the air in a hovering position. (See [link]). Figure 10 Ground vehicle 1 automatically searches for the nearest parking lot based on traffic conditions.

[0025] (4) After the flight cabin 3 takes off, the tail rotor 7 deflects 90° around its mounting axis and becomes fixed, transforming into a thrust propeller and generating forward thrust. At this time, the wing 4 generates lift. As the speed increases, the lift of the wing 4 increases, and the lift rotor 5 hidden inside the wing 4 begins to unload lift. The slide rail mechanism 21 inside the outer end of the wing controls the screw actuator to perform axial retraction movement through the communication control system. The connecting rod connected to the screw actuator moves the slider along the slide rail. The movable skins above and below the lift rotor 5 inside the wing 4 retract along the wing surface and return to the holes on the upper and lower surfaces of the rotor, closing the wing surface 4 and shutting down the lift rotor 5. At this time, the complete and smooth wing generates greater lift and reduces drag as the speed increases. The overall lift-to-drag ratio of the aircraft reaches its optimal level, and the aircraft will fly at a greater forward speed. See Figure 11 The ailerons 6 located at the rear of the inner section of the wing 4 and the deflector 9 at the rear of the obliquely mounted tail 8 provide aerodynamic forces for the aircraft's balance and attitude changes.

[0026] (5) In water gliding mode, the flying car operates in the same way as the flight cabin 3 after takeoff. It can approach the water surface and fly quickly by skimming the water like a ground effect vehicle or glide on the water surface like a boat.

[0027] (6) Underwater navigation mode (e.g., underwater operation is required for marine scientific research, submarine cable repair, or underwater exploration). First, the aircraft wing transitions from level flight mode to hovering mode. The sliding rail mechanism 21 inside the outer wing consists of a lead screw actuator 22, a connecting rod 23, a slider 24, and a sliding rail 25. See [reference needed]. Figure 6 The slider 24 is connected to the movable skin 26 on the wing. The slide rail 25 is fixed to the outer wing 4. The slider 24 is located on the slide rail 25. The communication control system controls the lead screw actuator 22 to move axially. The connecting rod 23 connected to the lead screw actuator 22 pushes the slider 24 to move along the slide rail 25. The movable skin 26 moves along the slide rail 25 with the slider 24. The lifting rotor 5 inside the wing 4 (see...) Figure 7 The movable skins on the upper and lower surfaces of the wing are moved away to expose the ducts on the upper and lower surfaces of the wing. The lift rotor 5 starts and generates lift. The deflector rotor 7 of the oblique tail 8 deflects 90° in the opposite direction around its mounting axis, generating a pull perpendicular to the plane of the oblique tail 8 duct. Its vertical component provides part of the lift. The flight cabin 3 lands on the water surface in a hovering manner. Then, seawater is injected into the float 16 at the bottom of the flight cabin through the water injection valve 14 at the tail, increasing gravity. When gravity is greater than buoyancy, the flight cabin 3 sinks. See Figure 12 , Figure 13When the communication control system detects that the flight cabin 3 has reached the designated depth, it controls the deflector 7 at the tail of the oblique tail 8 to deflect 90° around its mounting axis and fix it, generating forward thrust. The duct hole on the surface of the wing 4 is closed by the slide rail mechanism 21 at the outer end of the wing 4 and the lift rotor 5 is closed. The communication control system controls the deflector 7 to adjust its speed to adapt to the underwater propeller environment, and the flight cabin 3 conducts underwater navigation. When it is necessary to surface, the float 16 discharges seawater through the drain valve 15, and the weight of the flight cabin 3 decreases. When the weight is less than the buoyancy, the flight cabin 3 floats up and approaches the water surface. The flight cabin 3 then performs water surface taxiing takeoff or vertical climb to take off.

[0028] (7) When the flight cabin 3 receives the instruction to switch from flight mode to ground driving mode, the deflector 7 decelerates, the flight cabin 3 decelerates and descends and hovers, and searches for the nearest ground vehicle 1 through the network platform. After hovering and landing, the communication control system controls the electromagnetic spring buckle 13 to engage in the connecting slot 12, and the ground vehicle 1 and the flight cabin 3 are combined into one. The communication control system controls the hydraulic mechanism 17 on the end face rib of each segment of the wing to perform the closing operation. The inner and outer segments fold around the hinge connection mechanism 20, and the wing is folded up to reduce space occupation. The communication control system shuts down the ducted lift rotor 5 and the deflector 7. The modular amphibious multi-functional flying car drives on the ground under the control of the power system 10 and the communication and autopilot control system 11.

[0029] The above description merely illustrates embodiments of the present invention and is quite specific and detailed; however, it should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Furthermore, any parts of the present invention not described in detail are conventional techniques.
