Description

Technical Field

[0001] This invention relates to the field of amphibious vessel technology, specifically to an amphibious vessel capable of stable movement on land. Background Technology

[0002] Amphibious boats are multi-functional vehicles capable of operating in three different environments: land, water, and air. They can freely switch between these modes according to different mission requirements and environmental conditions, adapting to various complex terrains and scenarios. They can carry a variety of equipment and payloads for reconnaissance, patrol, rescue, transportation, sightseeing, and other missions, meeting the needs of different users.

[0003] When the amphibious assault boat is in flight, it generates lift through the rotors of its vertical takeoff and landing (VTOL) mechanism, allowing it to leave the ground or water surface. Simultaneously, it utilizes the propellers of its aerial propulsion system to provide forward thrust, enabling flight. During flight, the attitude and direction are controlled by adjusting the angles of the elevators and rudders. When the amphibious assault boat is navigating on the water, it uses water jet propulsion from its surface / underwater propulsion system to propel itself on the water. The rudder controls the boat's steering, enabling surface navigation. When the amphibious assault boat is traveling on land, it typically uses tracks or wheels mounted on its bottom, powered by electric motors, to propel itself. The steering mechanism controls the direction of travel.

[0004] To reduce air and water resistance, amphibious boats typically adopt a smooth, flat, streamlined hull. The bottom lacks sufficient space to install complex land-based support structures. In order to take off and land in the air and float on the water, the bottom of the amphibious boat may only be able to install miniaturized wheels or tracks, resulting in a small ground contact area and concentrated support points, making it easy to slip or capsize on uneven surfaces. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a amphibious boat that can move stably on the road surface, so as to solve the technical problems in the background art mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an amphibious boat capable of stable movement on a road surface, comprising a hull, mounting bases, and mounting slots, wherein multiple sets of mounting bases are installed on the outer wall of the hull, and mounting slots are symmetrically provided at one end of the hull; The hull is equipped with a flight drive module and an underwater drive module. Multiple sets of mounting bases are equipped with lift fan blades, and the multiple sets of lift fan blades are electrically connected to the flight drive module. Two sets of mounting slots are equipped with thrust fan blades, and the two sets of thrust fan blades are electrically connected to the underwater drive module.

[0007] By adopting the above technical solution, the problems of slipping and capsizing when the amphibious boat moves on the ground are solved. Before the amphibious boat lands on the ground, multiple sets of rollers and multiple sets of support seats are moved out of multiple installation compartments. The multiple sets of rollers and multiple sets of support seats are distributed at the bottom of the boat. After the boat lands on the ground, the multiple sets of rollers and multiple sets of support seats work together to support the boat.

[0011] Preferably, the two sets of first drive shafts rotate synchronously, thereby driving multiple sets of drive gears to rotate. The multiple sets of drive gears mesh with multiple sets of toothed plates, and the multiple sets of toothed plates move, thereby driving multiple sets of baffles to move.

[0012] The present invention is further configured such that the inner walls of the multiple sets of reserved grooves are symmetrically provided with limiting grooves, the outer walls of the multiple sets of baffles are symmetrically provided with protruding plates, and the multiple sets of protruding plates are respectively movably connected to the multiple sets of limiting grooves.

[0014] The present invention is further configured such that multiple sets of transmission bevel gears are installed on the outer walls of multiple sets of the first transmission shafts, and multiple sets of connecting shafts are movably installed inside the hull. Each set of connecting shafts has a connecting bevel gear installed at one end, and the multiple sets of connecting bevel gears are respectively meshed with the multiple sets of transmission bevel gears.

[0015] Preferably, the two sets of first drive shafts rotate, driving multiple sets of drive bevel gears to rotate. The multiple sets of drive bevel gears mesh with multiple sets of connecting bevel gears, and the multiple sets of connecting bevel gears rotate, driving multiple sets of connecting shafts to rotate.

[0016] The present invention is further configured such that multiple sets of movable cylinders are movably installed inside the hull, and the multiple sets of movable cylinders are respectively connected to multiple sets of connecting shafts by toothed synchronous belts.

[0017] Preferably, multiple sets of connecting shafts rotate, and the multiple sets of connecting shafts are respectively connected to multiple sets of movable cylinders through toothed synchronous belts, and the multiple sets of movable cylinders rotate.

[0018] The present invention is further configured such that each of the multiple sets of movable cylinder inner walls is movably installed with a telescopic column, and the outer walls of the multiple sets of telescopic columns are respectively threadedly connected to the inner walls of the multiple sets of movable cylinders, and one end of each of the multiple sets of telescopic columns is respectively connected to a multiple set of support seats.

[0019] Preferably, multiple sets of movable cylinders rotate, and the inner walls of the multiple sets of movable cylinders are respectively threaded to the outer walls of multiple sets of telescopic columns. One end of each set of telescopic columns is connected to a set of support seats. Therefore, the multiple sets of telescopic columns move, thereby driving the multiple sets of support seats to move.

[0020] The invention is further configured such that a second motor is installed inside the hull, and a second drive shaft is installed at the output end of the second motor.

[0021] Preferably, the second motor is started, driving the second drive shaft to rotate.

Before the amphibious boat lands on the ground, multiple sets of rollers and support seats are moved out of multiple installation compartments and are distributed at the bottom of the hull. After the hull lands on the ground, the multiple sets of rollers and support seats work together to support the hull. The support points are distributed, making it less likely to slip or capsize on uneven roads.

[0027] 2. This invention, by setting up installation compartments, reserved slots, and baffles, allows the amphibious boat to navigate underwater. Before navigation, two sets of first drive shafts rotate, driving multiple sets of transmission gears to rotate, thereby displacing multiple sets of baffles and telescopic columns. The telescopic columns move upward, causing multiple sets of support seats to move upward, and the support seats move into the interior of the installation compartments. The baffles move downward, reaching the bottom of the installation compartments and closing them. This allows the amphibious boat to enter underwater navigation, preventing water from entering the hull through the installation compartments and protecting the electronic components inside the hull.

[0031] The embodiments of the present invention will now be described.

[0032] A type of amphibious vessel capable of stable movement on land; see [link / reference]. Figure 1 - Figure 9 It includes a hull 1, mounting bases 2 and mounting slots 4. Multiple sets of mounting bases 2 are installed on the outer wall of the hull 1, and mounting slots 4 are symmetrically opened at one end of the hull 1. The hull 1 is equipped with a flight drive module and an underwater drive module. Multiple mounting bases 2 each have movably mounted lift fan blades 3, and these lift fan blades 3 are electrically connected to the flight drive module. When the amphibious boat is performing flight operations, the flight drive module inside the hull 1 is activated, driving the multiple lift fan blades 3 to rotate, thereby lifting the hull 1 upwards, allowing the amphibious boat to perform flight operations. Two mounting slots 4 each have movably mounted thrust fan blades 5, and these thrust fan blades 5 are electrically connected to the underwater drive module. When the amphibious boat is navigating in the water, the hull 1 falls into the water, the underwater drive module inside the hull 1 is activated, driving the two thrust fan blades 5 to rotate, allowing the hull 1 to travel in the water. Multiple installation chambers 8 are provided at the bottom of the hull 1, and the multiple installation chambers 8 are distributed in a dispersed manner. Each of the multiple installation chambers 8 has a support seat 21 that is movably installed inside. Each of the multiple support seats 21 has a limit shaft 22 that is movably installed inside. Each of the multiple limit shafts 22 has a roller 23 installed on its outer wall.

[0033] Please see Figure 3 A first motor 9 is installed inside the hull 1. A first drive shaft 10 is installed at the output end of the first motor 9. First transmission shafts 11 are symmetrically installed inside the hull 1. A toothed synchronous belt connects one set of first drive shafts 10 and one set of first transmission shafts 11. A toothed synchronous belt also connects the two sets of first transmission shafts 11. When the first motor 9 starts, it drives the first drive shaft 10 to rotate. The first drive shaft 10 is connected to the first set of first transmission shafts 11 through the toothed synchronous belt. When one set of first transmission shafts 11 rotates, the two sets of first transmission shafts 11 are connected through the toothed synchronous belt and rotate synchronously.

[0034] Please see Figure 3 - Figure 6 Multiple sets of transmission gears 12 are installed on the outer walls of both sets of first drive shafts 11. Multiple sets of reserved slots 6 are opened at the bottom of the hull 1. Baffles 13 are movably installed on the inner walls of the multiple sets of reserved slots 6. The multiple sets of baffles 13 are movably connected to multiple sets of installation chambers 8. Toothed plates 14 are symmetrically installed on the inner walls of the multiple sets of baffles 13. The multiple sets of transmission gears 12 are meshed with the multiple sets of toothed plates 14. The two sets of first drive shafts 11 rotate synchronously, thereby driving the multiple sets of transmission gears 12 to rotate. The multiple sets of transmission gears 12 are meshed with the multiple sets of toothed plates 14. The multiple sets of toothed plates 14 are displaced, thereby driving the multiple sets of baffles 13 to displace.

[0035] Please see Figure 3 - Figure 6 Multiple sets of reserved grooves 6 have symmetrically opened limiting grooves 7 on their inner walls, and multiple sets of baffles 13 have symmetrically installed protruding plates 15 on their outer walls. The multiple sets of protruding plates 15 are movably connected to the multiple sets of limiting grooves 7, which increases the sealing performance of the baffles 13 and improves the waterproof effect of the installation chamber 8.

[0036] Please see Figure 3 - Figure 5 Multiple sets of first drive shafts 11 are equipped with multiple sets of transmission bevel gears 16 on their outer walls. Multiple sets of connecting shafts 17 are movably installed inside the hull 1. Each set of connecting shafts 17 has a connecting bevel gear 18 installed at one end, and the multiple sets of connecting bevel gears 18 are respectively meshed with the multiple sets of transmission bevel gears 16. When the two sets of first drive shafts 11 rotate, they drive the multiple sets of transmission bevel gears 16 to rotate. The multiple sets of transmission bevel gears 16 are respectively meshed with the multiple sets of connecting bevel gears 18. When the multiple sets of connecting bevel gears 18 rotate, they drive the multiple sets of connecting shafts 17 to rotate.

[0037] Please see Figure 3 - Figure 5Multiple sets of movable cylinders 19 are installed inside the hull 1, and each set of movable cylinders 19 is connected to a set of connecting shafts 17 by a toothed synchronous belt. The multiple sets of connecting shafts 17 rotate, and the multiple sets of connecting shafts 17 are connected to the multiple sets of movable cylinders 19 by toothed synchronous belts.

[0038] Please see Figure 3 - Figure 7 Each set of movable cylinders 19 has a telescopic column 20 movably installed on its inner wall, and the outer walls of the telescopic columns 20 are threadedly connected to the inner walls of the movable cylinders 19. One end of each telescopic column 20 is connected to a support seat 21. When the movable cylinders 19 rotate, the inner walls of the movable cylinders 19 are threadedly connected to the outer walls of the telescopic columns 20, and one end of each telescopic column 20 is connected to a support seat 21. Therefore, the telescopic columns 20 move, thereby causing the support seats 21 to move.

[0039] Please see Figure 3 A second motor 25 is installed inside the hull 1. A second drive shaft 26 is installed at the output end of the second motor 25. When the second motor 25 is started, it drives the second drive shaft 26 to rotate.

[0040] Please see Figure 3 - Figure 9 Multiple sets of second drive shafts 27 are movably installed inside the hull 1, and each set of second drive shafts 27 is connected to the other by a toothed synchronous belt. Each set of second drive shafts 27 is connected to a second drive shaft 26 by a toothed synchronous belt. Each set of second drive shafts 27 has a groove 28 at both ends. A detection device is installed inside the hull 1 opposite to one set of grooves 28, and the detection device is electrically connected to a second motor 25. When the second drive shaft 26 rotates, it is connected to the set of second drive shafts 27 by a toothed synchronous belt. Thus, when the set of second drive shafts 27 rotates, the multiple sets of second drive shafts 27 are connected by synchronous belts and rotate synchronously. When the multiple sets of second drive shafts 27 stop rotating, the detection device detects the set of grooves 28. If the groove opening of the groove 28 is not facing upward, the detection device starts the second motor 25 to make the groove opening of the groove 28 face upward.

[0041] Please see Figure 3 - Figure 7 Multiple sets of limiting shafts 22 extend to one end of the outer wall of multiple sets of support seats 21 and are each equipped with a protrusion 24. The multiple sets of protrusions 24 are movably connected to multiple sets of grooves 28. Multiple sets of second drive shafts 27 rotate, driving the multiple sets of protrusions 24 to rotate, thereby driving the multiple sets of limiting shafts 22 to rotate.

[0042] The working principle of this invention is as follows: when the amphibious boat is sailing in the water, the hull 1 falls into the water, the underwater drive module inside the hull 1 is activated, driving the two sets of thrust fan blades 5 to rotate, and the hull 1 travels in the water. When the amphibious vessel is in flight operation, the flight drive module inside the hull 1 is activated, which drives multiple sets of lift fan blades 3 to rotate, thereby lifting the hull 1 upward, and the amphibious vessel is in flight operation. When the amphibious vessel is preparing to land from the air, the first motor 9 starts, driving the first drive shaft 10 to rotate. The first drive shaft 10 is connected to a set of first transmission shafts 11 by a toothed synchronous belt. The first set of first transmission shafts 11 rotates, and the two sets of first transmission shafts 11 are connected by a toothed synchronous belt. The two sets of first transmission shafts 11 rotate synchronously, thereby driving multiple sets of transmission gears 12 to rotate. The multiple sets of transmission gears 12 are respectively engaged with multiple sets of toothed plates 14. The multiple sets of toothed plates 14 move upward, thereby driving multiple sets of baffles 13 to move upward, thus exposing the installation compartment 8. When the two sets of first drive shafts 11 rotate, they drive multiple sets of drive bevel gears 16 to rotate. The multiple sets of drive bevel gears 16 are respectively meshed with multiple sets of connecting bevel gears 18. The multiple sets of connecting bevel gears 18 rotate, driving multiple sets of connecting shafts 17 to rotate. The multiple sets of connecting shafts 17 are respectively connected to multiple sets of movable cylinders 19 through toothed synchronous belts. The multiple sets of movable cylinders 19 rotate, and the inner walls of the multiple sets of movable cylinders 19 are respectively threaded to the outer walls of multiple sets of telescopic columns 20. One end of the multiple sets of telescopic columns 20 is respectively connected to multiple sets of support seats 21. Therefore, the multiple sets of telescopic columns 20 move downward, thereby driving the multiple sets of support seats 21 to move downward, and then driving the multiple sets of rollers 23 to move downward. After the multiple sets of rollers 23 move downward a certain distance, the multiple sets of installation chambers 8 open, and the multiple sets of rollers 23 move out of the multiple sets of installation chambers 8. When multiple sets of support seats 21 move downward, they drive multiple sets of protrusions 24 to move downward, causing the protrusions 24 to move into the interior of multiple sets of grooves 28. After the hull 1 lands on the ground, multiple sets of rollers 23 and multiple sets of support seats 21 work together to support the hull 1. The support points are distributed, making it less likely to slip or capsize on uneven surfaces. The second motor 25 starts, driving the second drive shaft 26 to rotate. The second drive shaft 26 is connected to a set of second transmission shafts 27 by a toothed synchronous belt, so the set of second transmission shafts 27 rotates. Multiple sets of second transmission shafts 27 are connected by synchronous belts, and the multiple sets of second transmission shafts 27 rotate synchronously, thereby driving the multiple sets of protrusions 24 to rotate, which in turn drives the multiple sets of limit shafts 22 to rotate, and then drives the multiple sets of rollers 22 to rotate, causing the hull 1 to move.
