Description

Technical Field

[0001] The present application relates to the field of transportation equipment, and in particular to a land and air dual-purpose aircraft. Background Art

[0002] Transportation equipment is the carrier of goods from one place to another, and is a tool of transportation. Since transportation is completed with the help of certain transportation tools and through certain transportation routes and ports, the transportation method depends on the type and nature of the transportation tools, transportation routes and ports used. Transportation equipment is divided into road transportation equipment, railway transportation equipment, aviation transportation equipment, water transportation equipment and pipeline transportation equipment according to the transportation method.

[0003] However, for complex and changeable transportation routes, the transportation of goods is usually achieved by replacing transportation equipment, which requires more time and resources to be spent on transshipment, thus reducing transportation efficiency. Summary of the invention

[0004] In order to improve transportation efficiency, the present application provides a land and air dual-purpose aircraft.

[0005] The present application provides a dual-purpose land and air vehicle that adopts the following technical solution: A dual-purpose land and air vehicle comprises a box body, a plurality of base frames are arranged below the box body, flywheels are arranged on both sides of the base frames, and the total number of flywheels on one side of all the base frames is greater than or equal to four, a steering assembly is arranged between the base frames and the flywheels, and a lift assembly is arranged on the flywheels.

[0006] By adopting the above technical solution, the flywheel is connected to the base frame through the rotating assembly and supports the box. When the flywheel is supported on the ground, the flywheel is rotated so that the box can move on the ground. The steering assembly makes the two flywheels on each side horizontal. The horizontal flywheel rotates rapidly, and the lift assembly provides lift for the whole, so that the box takes off. When the box is in the air, the steering assembly adjusts the remaining flywheels to horizontal, thereby providing lift for the box. When the box needs to descend, a part of the flywheel is first adjusted to vertical and gradually descends to touch the ground, and then the remaining flywheels are rotated to vertically touch the ground. In this way, the box can move on land and in the air, thereby adapting to complex traffic environments and improving transportation efficiency.

[0007] Optionally, the steering assembly includes a first rotating rod rotatably connected to the center of the flywheel, an end of the first rotating rod away from the flywheel is provided with a driving motor for driving the flywheel to rotate, a second rotating rod perpendicular to the first rotating rod is fixedly connected to the first rotating rod, a connecting sleeve is rotatably connected to the second rotating rod, the connecting sleeve is arranged in a Z shape, a steering motor for driving the second rotating rod to rotate is provided on the connecting sleeve, the end of the connecting sleeve away from the second rotating rod is rotatably connected to a base frame, and an adjusting motor for driving the connecting sleeve to rotate is provided on the base frame.

[0008] By adopting the above technical solution, when the adjusting motor drives the connecting sleeve to rotate, the steering motor on the connecting sleeve simultaneously drives the second rotating rod to rotate. With the cooperation of the adjusting motor and the steering motor, the flywheel is adjusted from a vertical state to a horizontal state, and at the same time, the driving motor drives the flywheel to rotate, thereby driving the lift assembly to provide lift for the box.

[0009] Optionally, the base frame is configured to be cylindrical and rotatably connected to the box body, and a driving member for driving the base frame to rotate is provided inside the box body.

[0010] By adopting the above technical solution, the chassis rotates to adjust the angle of the flywheel, so that when the flywheel rolls on the ground, it can provide a steering effect for the box.

[0011] Optionally, the flywheel includes an annular hub, an inner sleeve rotatably connected to the first rotating rod is provided inside the hub, the lift assembly is connected between the inner sleeve and the hub, and the lift assembly includes a plurality of wing plates, which are evenly distributed around the inner sleeve and fixedly connected to the inner sleeve and the hub.

[0012] By adopting the above technical solution, when the first rotating rod drives the inner sleeve to rotate, the inner sleeve drives the wing plate and the wheel hub to rotate synchronously, and the wing plate provides lift for the flywheel during the rotation process.

[0013] Optionally, the wing panel includes a plurality of single wings arranged side by side and connecting members for connecting the single wings, the upper side surface of the single wing is set as a curved surface, an air duct is opened inside the single wing, the air duct includes an air inlet and an air outlet, lift members are provided on both sides of the air inlet, and the number of lift members on the side of the air inlet close to the upper side surface of the single wing is less than the number of lift members on the other side.

[0014] By adopting the above technical scheme, the difference in the number of lift members on both sides inside the air inlet makes the air flow velocity on one side of the air inlet close to the upper side of the wing smaller than the air flow velocity on the other side, thereby reducing the possibility of air flow turbulence inside the air inlet causing vibration of the wing. At the same time, the curved surface of the upper side of the wing makes the air flow velocity large and the pressure low, while the air flow velocity on the lower side of the wing is slow and the pressure is high. The pressure inside the wing is greater than that on the upper side of the wing, but lower than that on the lower side of the wing. Therefore, the pressure on the lower side of the wing is greater than the pressure on the air inlet close to the lower side of the wing, thereby increasing the lift of the wing. At the same time, the pressure on the side of the air inlet close to the upper side of the wing is greater than the pressure on the upper side of the wing, thereby further increasing the lift of the wing. All the wings are connected together by connecting members to generate greater lift, thereby completing the lifting of the box.

[0015] Optionally, the lift member includes a partition plate, and a guide groove corresponding to the partition plate is provided on the inner wall of the air inlet, and a slope protruding toward the center line of the air inlet is provided on the side of the guide groove away from the air outlet.

[0016] By adopting the above technical scheme, when the airflow flows to the slope, a negative pressure area is formed between the partition plate and the slope, so that the speed increasing channel between the partition plate and the guide groove forms a near vacuum, thereby applying a forward-flowing suction and pulling force to the airflow in the channel on the side of the partition plate away from the slope, so that the airflow in the air inlet can flow quickly, and the number of lift members on both sides of the air inlet is different, resulting in different airflow velocities on both sides, and the pressure on the lower side of the single wing is greater than the pressure on the side of the air inlet close to the lower side of the single wing, and the pressure on the side of the air inlet close to the upper side of the single wing is greater than the pressure close to the lower side of the single wing, forming a pressure difference in the air inlet drainage channel, generating an upward lift.

[0017] Optionally, the direction of the air outlet is consistent with the curvature of the corresponding position on the upper side of the single wing, a diverter plate is provided at the middle position of the air outlet, the length of the diverter plate is smaller than the air outlet, and the diverter plate is consistent with the direction of the air outlet.

[0018] By adopting the above technical solution, when the airflow from the air inlet reaches the air outlet, thrust is applied to the side of the air outlet close to the upper side of the single wing, so that the air outlet obtains an upward thrust, further enhancing the lift of the single wing. Finally, at the outlet of the air outlet, the two airflows converge to form a vortex, which then lifts the single wing again. The splitter separates the airflows on both sides of the air inlet at the air outlet, reducing the possibility of vibration of the single wing caused by airflow collision. Therefore, with the addition of multiple lifts, the lift of the single wing is greatly enhanced.

[0019] Optionally, a plurality of through holes are provided on the single wing, and the through holes on all the single wings are arranged correspondingly, and a connecting rod is further provided in the through holes of the single wings, and the connecting rod passes through all the single wings along the through holes and is fixedly connected to the wheel hub and the inner sleeve.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: By changing the angle of the flywheel through the steering assembly, the box can be used both on land and in the air. According to the actual situation, the mode of transportation can be changed to improve transportation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] The present application embodiment discloses a dual-purpose land and air vehicle. Figure 1 and Figure 2 A dual-purpose land and air vehicle includes a box body 1, two chassis 2 are installed below the box body 1, the chassis 2 is set in a cylindrical shape and is rotatably connected to the box body 1, and a driving member for driving the chassis 2 to rotate is provided inside the box body 1. Two flywheels 3 are provided on both sides of the chassis 2, that is, four flywheels 3 are provided on one side of the box body 1, a steering assembly 4 connecting the chassis 2 and the flywheel 3 is provided between the chassis 2 and the flywheel 3, and a lift assembly 33 is provided on the flywheel 3.

[0029] The chassis 2 rotates to adjust the angle of the flywheel 3, so that when the flywheel 3 rolls on the ground, it can provide a steering effect for the box 1. The flywheel 3 is connected to the chassis 2 through a rotating assembly and supports the box 1. When the flywheel 3 is supported on the ground, the flywheel 3 is rotated, and the box 1 can move on the ground. When the box 1 needs to be lifted, the steering assembly 4 drives the two flywheels 3 on both sides of the box 1 to adjust from a vertical state to a horizontal state. The horizontal flywheel 3 rotates quickly, and the lift assembly 33 provides a lift for the whole, so that the box 1 takes off. When the box 1 is in the air, the steering assembly 4 adjusts the remaining flywheel 3 to a horizontal state, thereby providing a lift for the box 1. When the box 1 needs to descend, the flywheel 3 adjusted to a horizontal state later is first adjusted to a vertical state, and gradually descends to abut the ground, and then the remaining flywheel 3 is rotated to a vertical state to touch the ground, so that the box 1 can move on land and in the air, thereby adapting to complex traffic environments.

[0030] Reference Figure 2 and Figure 3 The flywheel 3 includes a circular hub 31, an inner sleeve 32 rotatably connected to a first rotating rod 41 is provided inside the hub 31, a lift assembly 33 is connected between the inner sleeve 32 and the hub 31, a steering assembly 4 includes a first rotating rod 41 inserted in the inner sleeve 32 and rotatably connected to the inner sleeve 32, a driving motor for driving the flywheel 3 to rotate is provided at one end of the first rotating rod 41 away from the flywheel 3, a second rotating rod 42 perpendicular to the first rotating rod 41 is fixedly connected to the first rotating rod 41, a connecting sleeve 43 is rotatably connected to the second rotating rod 42, the connecting sleeve 43 is arranged in a Z shape, a steering motor for driving the second rotating rod 42 to rotate is installed on the connecting sleeve 43, and one end of the connecting sleeve 43 away from the second rotating rod 42 is rotatably connected to the chassis 2, and an adjusting motor for driving the connecting sleeve 43 to rotate is installed on the chassis 2. Among them, the driving motor, the steering motor and the adjusting motor are not specifically shown in the figure.

[0031] When the adjusting motor drives the connecting sleeve 43 to rotate, the steering motor on the connecting sleeve 43 simultaneously drives the second rotating rod 42 to rotate. With the cooperation of the adjusting motor and the steering motor, the flywheel 3 is adjusted from a vertical state to a horizontal state. When the driving motor drives the inner sleeve 32 to rotate, the flywheel 3 rotates with the inner sleeve 32, so that the lift assembly 33 provides lift for the box 1.

[0032] Reference Figure 3 and Figure 4 The lift assembly 33 includes a plurality of wing plates 331, which are evenly distributed around the inner sleeve 32 and fixedly connected to the inner sleeve 32 and the wheel hub 31. The inner sleeve 32 drives the wing plates 331 and the wheel hub 31 to rotate synchronously, and the wing plates 331 provide lift for the flywheel 3 during rotation.

[0033] Reference Figure 4 and Figure 5The wing plate 331 includes a plurality of single wings 332 arranged side by side and a connecting piece for connecting the single wings 332. The upper side surface of the single wing 332 is set as an arc surface. An air duct 333 is opened inside the single wing 332. The air duct 333 includes an air inlet 334 and an air outlet 335. Lifting pieces are arranged on both sides of the air inlet 334. The number of lifting pieces on the side of the air inlet 334 close to the upper side surface of the single wing 332 is less than the number of lifting pieces on the other side.

[0034] The difference in the number of lift members on both sides of the air inlet 334 makes the air flow velocity on one side of the air inlet 334 close to the upper side of the single wing 332 smaller than the air flow velocity on the other side, thereby reducing the possibility of air flow turbulence inside the air inlet 334 causing vibration of the single wing 332. At the same time, the curved surface of the upper side of the single wing 332 makes the air flow velocity large and the pressure low, while the air flow velocity on the lower side of the single wing 332 is slow and the pressure is large. The pressure inside the single wing 332 is greater than the upper side of the single wing 332, but lower than the pressure on the lower side of the single wing 332. Therefore, the pressure on the lower side of the single wing 332 is greater than the pressure on the air inlet 334 close to the lower side of the single wing 332, thereby increasing the lift of the single wing 332. At the same time, the pressure on the side of the air inlet 334 close to the upper side of the single wing 332 is greater than the pressure on the upper side of the single wing 332, thereby further increasing the lift of the single wing 332. All the single wings 332 are connected together by connecting members to generate greater lift, thereby completing the lifting of the box body 1.

[0035] The lifting member includes a partition plate 336 , and a guide groove 337 corresponding to the partition plate 336 is formed on the inner wall of the air inlet 334 . A slope 338 protruding toward the center line of the air inlet 334 is formed on the side of the guide groove 337 away from the air outlet 335 .

[0036] When the airflow flows to the slope 338, a negative pressure area is formed between the partition plate 336 and the slope 338, so that the speed increase channel between the partition plate 336 and the guide groove 337 forms a near vacuum, thereby applying a forward-flowing suction and pulling force to the airflow in the channel on the side of the partition plate 336 away from the slope 338, so that the airflow in the air inlet can flow quickly. The different numbers of lift members on both sides of the air inlet result in different airflow velocities on both sides, and the pressure on the lower side of the single wing 332 is greater than the pressure on the side of the air inlet close to the lower side of the single wing 332, and the pressure on the side of the air inlet close to the upper side of the single wing 332 is greater than the pressure on the lower side of the single wing 332, forming a pressure difference in the air inlet drainage channel, generating an upward lift.

[0037] The direction of the air outlet 335 is consistent with the curvature of the corresponding position on the upper side of the single wing 332. A splitter plate 339 is provided at the middle position of the air outlet 335. The length of the splitter plate 339 is less than that of the air outlet 335, and the splitter plate 339 is consistent with the direction of the air outlet 335. When the airflow from the air inlet 334 reaches the air outlet 335, a thrust is applied to the side of the air outlet 335 close to the upper side of the single wing 332, so that the air outlet 335 obtains an upward thrust, further improving the lift of the single wing 332. Finally, at the outlet of the air outlet 335, the two airflows converge to form a vortex, and then lift the single wing 332 again. The splitter plate 339 separates the airflows on both sides of the air inlet at the air outlet, reducing the possibility of airflow collision causing vibration of the single wing 332. Therefore, with the support of multiple lifts, the lift of the single wing 332 is greatly improved.

[0038] A plurality of through holes 3321 are provided on the single wing 332 , and the through holes 3321 on all the single wings 332 are arranged correspondingly, the connecting member is arranged as a connecting rod 3322 , and the connecting rod 3322 passes through the through holes 3321 of all the single wings 332 on the same wing plate 331 , and the connecting rod 3322 is fixedly connected to the hub 31 and the inner sleeve 32 .

[0039] When the flywheel 3 rotates, the single wing 332 on each wing plate 331 provides lift through the wind passing through the wind duct 333, thereby enabling the box body 1 to be lifted quickly.

[0040] The implementation principle of a land and air amphibious aircraft in an embodiment of the present application is as follows: when the flywheel 3 is supported on the ground, the flywheel 3 is rotated and the box 1 can move on the ground. When the box 1 needs to be lifted off, the steering assembly 4 drives the two flywheels 3 on both sides of the box 1 to adjust from a vertical state to a horizontal state. The horizontal flywheel 3 rotates rapidly, and provides lift for the whole through the wing plate 331, so that the box 1 takes off. When the box 1 is in the air, the steering assembly 4 adjusts the remaining flywheel 3 to a horizontal state, thereby providing lift for the box 1. When the box 1 needs to descend, the flywheel 3 adjusted to a horizontal state later is first adjusted to a vertical state, and gradually descends to touch the ground, and then the remaining flywheel 3 is rotated to a vertical state to directly touch the ground, so that the box 1 can move on land and in the air.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
