Description

Technical Field

[0001] The present invention relates to the technical field of intelligent transportation equipment, and particularly to an in-wheel-clutch type wheel-wing shared land-air amphibious transportation platform. Background Art

[0002] As a multi-functional mobile platform integrating ground travel and low-altitude flight functions, the land-air amphibious transportation platform can flexibly switch among multi-domain scenarios such as land, low altitude, near shore, and underground pipe corridors, and perform various tasks such as transportation, reconnaissance, rescue, and surveying. Compared with traditional transportation tools, such as aircraft or automobiles, its operating dimensions and domains have been qualitatively improved. It can not only effectively utilize land and low-altitude space, but also break through the limitations of vehicles in complex environments, and has higher flexibility, mobility, and adaptability. The land-air amphibious mobile platform has broad application prospects in the fields of military transportation, emergency rescue, and smart city construction. For example, in the civilian field, it can be applied to diverse scenarios such as disaster rescue, terrain survey, and urban traffic guidance.

[0003] Despite the significant advantages of the land-air amphibious transportation platform, its technological development still faces many challenges. Currently, most land-air amphibious technologies are in the prototype research and development stage, and the technical routes are scattered, and the core technologies of the automotive and aviation fields have not been fully integrated. Most existing land-air amphibious systems adopt a wheel-wing separation structure, that is, two sets of independent drive systems are equipped: one is a wheel drive system for ground travel, and the other is a rotor drive system for air flight. Although this design realizes land-air amphibiousness in terms of function, it also brings problems such as complex systems, large overall dimensions, and increased weight, seriously restricting the passability and mobility of the land-air amphibious mobile platform in complex environments such as narrow sections, tidal flats, mountains, and pipe corridors, and it is even more difficult to meet the task requirements of diverse special operations in complex environments.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] (1) By integrating the blade motor assembly, clutch assembly, and wheel assembly into a clutch-wheel-wing shared mechanism, the present invention realizes the integration of the wheel and rotor within a single module. This can reduce space occupancy, decrease the overall size and weight of the amphibious land-air carrier platform, thereby enhancing the compactness and load capacity of the carrier platform.

[0024] (2) The present invention utilizes the clutch assembly to control the drive conversion between the wheel and rotor, enabling the carrier platform to complete the flight mode switch during driving without the need to stop the entire machine. This rapid mode conversion not only saves time but also greatly improves the convenience and stability of the mode switch, enhancing the adaptability of the carrier platform in complex environments.

[0025] (3) The present invention forms a ducted structure by the circumferential pipe parts of components such as the motor bracket, electromagnetic clutch bracket, and vane-type rim, enclosing the blades therein, effectively reducing the aerodynamic noise generated by the rotor. The ducted structure restricts the airflow path, forming a directional acceleration flow field, which can improve the aerodynamic efficiency of the rotor system; and the fully enclosed ducted structure can provide physical protection for high-speed rotating components, resisting bird strikes and foreign object intrusion, ensuring safe operation in complex urban environments; in addition, the integrated ducted design can also optimize the overall aerodynamic shape of the machine, reducing energy consumption by reducing air resistance.

[0026] (4) The present invention integrates the clutch-wheel-wing shared mechanism and the related lifting and flipping mechanism on the side of the fuselage, and the lifting and flipping mechanism adjusts the distance and axis direction between the clutch-wheel-wing shared mechanism and the ground. Such an integrated design realizes functional integration, making the overall structure more compact and efficient. It reduces the mutual interference between mechanisms and simplifies the control process.

[0027] (5) The present invention adopts a modular design, and the clutch-wheel-wing shared mechanism and the lifting and flipping mechanism can be assembled in any even number to different-sized carrier platforms. This modular characteristic enables the carrier platform to flexibly adjust the switching method of the "travel / fly" mode according to specific mission requirements. By increasing or decreasing the number of modules, it can adapt to different-sized carrier platforms, thus meeting the transportation needs in various complex environments.

It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. In addition, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0034] In order to illustrate the effectiveness of the method proposed by the present invention, the above - mentioned technical solutions of the present invention will be described in detail below through a specific embodiment. Figure 1 Schematic diagram of an amphibious air - land transport platform with a built - in clutch and combined wheel - wing mechanism according to an embodiment of the present invention. Figure 2 Schematic diagram of one group of built - in clutch - type combined clutch - wheel - wing mechanisms according to an embodiment of the present invention.

[0035] The following, in combination with Figure 1 and Figure 2 , the structure of the amphibious air - land transport platform with a built - in clutch and combined wheel - wing mechanism according to an embodiment of the present invention will be described.

[0036] As Figure 1 shown, the present invention provides an amphibious air - land transport platform 1 with a built - in clutch and combined wheel - wing mechanism, including: a fuselage 2, the two sides of the fuselage 2 are symmetric with each other, the fuselage 2 has a cabin, a plurality of lifting and flipping mechanisms are provided on both sides of the fuselage 2, the lifting and flipping mechanisms on both sides are symmetric with each other along the axis of the fuselage 2, and the combined clutch - wheel - wing mechanism 100 is connected to the fuselage 2 through the lifting and flipping mechanisms.

[0037] Inside the cabin of the fuselage 2, there is a flight control module which is used to obtain external environment and instruction information and provide control information to control the operation of the clutch wheel-wing shared mechanism 100 and the attitude conversion of the lifting and flipping mechanism. Inside the cabin of the fuselage 2, there is a battery and a power distribution board which are used to distribute power to each component and play a role in regulating voltage.

[0038] In some embodiments, the flight control module may include a processor and sensors. The sensors obtain external environment information, and the processor receives and processes the external environment information, generates control information based on a control algorithm, and controls the operation of the clutch wheel-wing shared mechanism 100 and the attitude conversion of the lifting and flipping mechanism.

[0039] As Figure 2 shown, the clutch wheel-wing shared mechanism 100 included in the built-in clutch type wheel-wing shared land-air amphibious carrier platform 1 provided by the present invention will be described below.

[0040] The clutch wheel-wing shared mechanism 100 includes a blade motor assembly 110, a clutch assembly 120, and a wheel assembly 130 connected in sequence.

[0041] The blade motor assembly 110, the clutch assembly 120, and the wheel assembly 130 all have a rotation axis, and the rotation axes maintain a collinear relationship to ensure the efficiency and stability of power transmission between the assemblies.

[0042] In some embodiments, the blade motor assembly 110 is connected to the clutch assembly 120, and the blade motor assembly 110 is connected to the lifting and flipping mechanism. The blade motor assembly 110 includes: a drive motor 111, a blade 112, and a motor bracket sleeve 113; the blade 112 is fixedly connected to the rotor of the drive motor 111 by bolts and can rotate at a high speed; the motor bracket sleeve 113 is fixed on the outer periphery of the drive motor 111, and the motor bracket sleeve 113 is connected to the lifting and flipping mechanism to connect the entire blade motor assembly 110 to the vehicle body. The drive motor 111 serves as the power source of the entire device, directly drives the blade 112 to rotate by rotating the rotor, and at the same time maintains the accuracy of the rotation axis.

[0043] In some embodiments, the clutch assembly 120 includes an electromagnetic clutch fixed end 121, an electromagnetic clutch switch 122, and an electromagnetic clutch bracket 123. The clutch assembly 120 has a rotatable part inside. The electromagnetic clutch fixed end 121 is fixed to the rotor of the drive motor 111 and driven by it, and the vane-type rim 132 is fixedly connected to the rotatable part inside the electromagnetic clutch.

[0044] When the clutch assembly 120 is operating, it has two states: engaged and disengaged. When the clutch assembly 120 is in the engaged state, the electromagnetic clutch switch 122 is open, and the torque of the drive motor 111 is transmitted to the wheel assembly 130. When the clutch assembly 120 is in the disengaged state, the electromagnetic clutch switch 122 is closed, and the torque of the drive motor 111 is no longer transmitted to the wheel assembly 130.

[0045] In some embodiments, the wheel assembly 130 is connected to the clutch assembly 120. The wheel assembly 130 includes: a tire 131, a vane-type rim 132, and a wheel housing 133. The vane-type rim 132 is fixedly connected to the output end of the clutch assembly 120. The tire 131 is fixed to the outer periphery of the vane-type rim 132 and is used to provide ground adhesion during land travel. The wheel housing 133 is fixed to the vane-type rim 132 and is used to induce air flow, optimize the air flow direction, and reduce air resistance during operation.

[0046] In some embodiments, a wide-diameter bearing 135 is provided between the vane-type rim 132 and the rotating shaft, which can support and reduce friction, enabling the vane-type rim 132 to rotate smoothly and efficiently relative to the rotating shaft.

[0047] In some embodiments, when the clutch assembly 120 is in the disengaged state, the drive motor 111 does not drive the vane-type rim 132 but only drives the paddle 112 to rotate to achieve the flight mode. When the clutch assembly 120 is in the engaged state, the drive motor 111 drives the vane-type rim 132 to rotate, and then drives the wheel assembly 130 to rotate to achieve the ground travel function.

[0048] The motor bracket 113 in the paddle motor assembly 110 of the present invention, the electromagnetic clutch bracket 123 in the clutch assembly 120, and the vane-type rim 132 in the wheel assembly 130 all have circumferential pipe portions. The circumferential pipe portions of the motor bracket 113, the electromagnetic clutch bracket 123, and the vane-type rim 132 are sleeved together with the circumferential portion of the wheel housing 133 to jointly form a duct structure 5, and the paddle 112 is located inside the duct structure.

[0049] The ducted structure of the present invention is wrapped by multiple circumferential ducts to form a sound insulation barrier, which can reduce aerodynamic noise and significantly improve the low-altitude flight environment in the city. At the same time, the ducted structure forms a directional acceleration flow field by restricting the airflow path, which can reduce the turbulent loss while improving the aerodynamic efficiency of the rotor system. Compared with the open rotor, the lift coefficient can be increased by 15-20%. The fully enclosed structure provides physical protection for high-speed rotating components, effectively resisting bird strikes and foreign object intrusion, and meeting the safety operation requirements of unmanned systems in complex urban environments. The integrated ducted design can also optimize the aerodynamic shape of the whole machine, and reduce the energy consumption by 12-18% by reducing air resistance.

[0050] Figure 3 Schematic diagram of the lifting and flipping mechanism provided by the present invention. The following will be combined with Figure 3 Describe the structure of one set of the lifting mechanism and the flipping mechanism provided according to the embodiments of the present invention.

[0051] The present invention provides a lifting and flipping mechanism, including a lifting mechanism 31 and a flipping mechanism 41.

[0052] The lifting mechanism 31 includes a lifting servo 311, a lifting worm gear 312, a lifting worm 313, a lead screw 314 and a fixed frame 315. The output end of the lifting servo 311 is connected to the lifting worm 313. The lifting worm gear 312 meshes with the lifting worm 313. The lifting worm gear 312 is fixedly connected to the screw of the lead screw 314. The nut of the lead screw 314 is fixed on the fixed frame 315. The rotation centers of the lifting worm gear 312 and the screw of the lead screw 314 are perpendicular to the ground. When the lifting servo 311 operates, it drives the lifting worm 313 to rotate the lifting worm gear 312, and then drives the lead screw 314 to lift the fixed frame 315 perpendicular to the ground by a preset distance.

[0053] In some embodiments, three or four flipping mechanisms 41 are evenly and dispersedly arranged on each side of the fuselage 2, and lifting mechanisms 31 are respectively arranged at the four corners of the fuselage 2.

[0054] In some embodiments, the lead screw 314 can be a trapezoidal lead screw, a ball screw, etc., but not limited thereto.

[0055] In some embodiments, the lifting servo 311 can be a stepper motor, a servo motor, etc., but not limited thereto. The torque, speed and other parameters of the lifting servo 311 are determined by the weight of the carrier platform and the required lifting speed.

[0056] In some embodiments, the fixed frame 315 is slidably connected to the fuselage 2, and the fixed frame 315 can slide up and down in a direction perpendicular to the ground. Each side of the fixed frame 315 has a bracket, and through holes are provided on the brackets.

[0057] The flipping mechanism 41 includes a flipping servo 411, a flipping worm gear 412, a flipping worm 413, a transmission shaft 414, and a flipping fixed bracket 415. The flipping servo 411 is fixed on the bracket on one side of the fixed bracket 315. The output end of the flipping servo 411 is connected to the flipping worm 413. The flipping worm gear 412 meshes with the flipping worm 413. The flipping worm gear 412 is fixedly connected to the transmission shaft 414. The transmission shaft 414 passes through the through hole in the bracket on one side of the fixed bracket 315. One end of the transmission shaft 414 extending out of the through hole is fixed with the flipping fixed bracket 415. The rotation center of the transmission shaft 414 is parallel to the ground. There is also a rotating shaft and a flipping fixed bracket 415 in the through hole in the bracket on the other side of the fixed bracket 315.

[0058] The flipping fixed bracket 415 is fixed to the blade motor assembly 110. In some embodiments, the flipping fixed bracket 415 is fixed to the motor bracket sleeve 113 of the blade motor assembly 110. When the flipping fixed bracket 415 rotates, it can drive the overall flipping of the clutch wheel and wing sharing mechanism 100, changing the axis direction of the clutch wheel and wing sharing mechanism 100.

[0059] In some embodiments, when the flipping fixed bracket 415 drives the clutch wheel and wing sharing mechanism 100 to flip, the rotation center line of the clutch wheel and wing sharing mechanism 100 can achieve the conversion between two states, including the conversion from being parallel to the ground to being perpendicular to the ground and the conversion from being perpendicular to the ground to being parallel to the ground. When the rotation center line is parallel to the ground, the clutch wheel and wing sharing mechanism 100 acts as a wheel, enabling the carrier platform to travel on the ground. When the rotation center line is perpendicular to the ground, the clutch wheel and wing sharing mechanism 100 provides lift to enable the carrier platform to fly. That is, the switching between the two states of being perpendicular and parallel to the ground is realized.

[0060] In some embodiments, the flipping servo 411 can be a stepper motor, a servo motor, etc., but is not limited thereto. The parameters such as the torque and speed of the flipping servo 411 are determined by the weight of the clutch wheel and wing sharing mechanism and the required flipping speed.

[0061] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0062] In the present invention, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or may include the first and second features not being in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature.
