Description

Amphibious bus}

Field of the Invention [0002] The present invention relates to an amphibious bus, and more particularly, to an amphibious bus capable of automatic conversion from a land mode to a land mode or from a land mode to a water mode.

In general, hybrid vehicles are vehicles that can simultaneously operate roads and other transportation routes. Typically, amphibious vehicles that can drive both roads and aqueducts are examples.

An amphibious vehicle is a car that combines a wheel or caterpillar to travel on land, and a structure (buoyancy, driven by a propeller or a webboard) to navigate the watercraft, .

These amphibious vehicles are mainly used as military or personal leisure activities.

For military purposes, it is possible to drive the road by means of an auxiliary structure, as well as by running on the watercourse, with a track (caterpillar), which is intended for military purposes and is intended mainly for easy travel in unsealed or field.

Therefore, there is a problem that military amphibious vehicles are restricted from traveling on packed roads such as asphalt. That is, since the packed roads are damaged, they are restricted to military use as a structure unpacked or combined in the field.

Conventional amphibious vehicles used for leisure activities are mainly ATVs (All-Terrain Vehicle), and they can be used as an all-terrain vehicle through an auxiliary structure of the hull, ie, running in marine, lakes, rivers and waterways, Although driving is smoothly carried out, there is a problem in safety and ride quality for the purpose of transportation rather than leisure.

That is, in the open form, when water is running, water is splashed to cause a feeling of discomfort such as wetting of clothing, etc., and it is small and influenced by waves and water.

In addition, since the passenger is required to run the road in a state in which the passenger is exposed to the danger, and the ATV is limited also to the lane (at least the first lane) in which the ATV can travel, There is a limit to how to replace the means of transportation as well as the running of the vehicle.

Accordingly, numerous researches and developments have been made to develop an amphibious bus capable of solving the above problems.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an amphibious bus in which conversion between an aquatic mode and a land mode can be automatically performed.

An amphibious bus according to an embodiment of the present invention includes: a hull; An engine for generating power for propelling the hull; A water propulsion device that receives the power from the engine and propels the hull from an aquarium; An onshore propulsion device that receives the power from the engine and propels the hull on land; A first drive shaft connecting the engine and the water-propulsion unit to transmit power transmitted from the engine to the water-propulsion unit; A second drive shaft connecting the engine and the onshore propulsion device to transmit power transmitted from the engine to the onshore propulsion device; A first clutch for controlling whether the first drive shaft is driven; A second clutch for controlling whether the second drive shaft is driven or not; A water sensing tank formed to be able to receive a fluid inside the hull; And a control unit that receives the level information of the fluid received in the aeration tank and controls the first clutch and the second clutch to select the driving of the watercraft or the onshore propulsion device, And controls the power generated by the engine to be transmitted only to the water-pumping propulsion device when the water level sensed by the water-sensing tank is equal to or higher than a predetermined water level, the first clutch is engaged and the second clutch is released, When the water level sensed by the tank is lower than a predetermined level, the first clutch is released and the second clutch is engaged so that the power generated by the engine is transmitted only to the onshore propulsion device.

Specifically, the water sensing tank may be disposed at a front lower portion of the hull to allow the fluid to flow into the hull by progress of the hull.

Specifically, the water sensing tank may be formed at the lowermost portion of the inflow hole through which the fluid flows, and may be formed so as to observe the traveling direction of the hull.

Specifically, the water sensing tank may further include a sensing sensor for measuring a level of the fluid received in the water sensing tank.

The control unit may further include an alarm unit for alarming the user whether the watercraft or the land mode is switched to the user aboard the hull, wherein the control unit receives the fluid level from the detection sensor by wire or wirelessly And when the level of the fluid is within the upper and lower range of 5% or less based on the predetermined level of the aeration tank, the alarm unit can be operated.

The amphibious bus according to the embodiment of the present invention detects the position of the amphibious bus through the water level of the water detection tank and determines whether the position of the amphibious bus is a prize or a land and then automatically converts from a land mode to a land mode So that smooth amphibious traffic can be achieved.

In the amphibious bus according to the embodiment of the present invention, it is possible to promptly determine whether the water sensing tank is disposed in front of the ship and whether it is water or land, and the inflow hole is disposed at the lowermost side of the water sensing tank, It is possible to prevent the water level judgment error from occurring.

Further, the amphibious bus according to the embodiment of the present invention sets an error judgment range within a range of 5% of the predetermined water level without depending only on the predetermined water level, and detects a sudden water level fluctuation In this case, an alarm unit is provided to allow an intuitive determination by the user, thereby preventing a mistake of the control unit detecting whether the vehicle is in the water or the land.

Also, the amphibious bus according to the embodiment of the present invention can realize the rolling of the wheels in the land mode through the single propulsion engine and the clutch and can realize the screw rotation in the airstream mode, thereby reducing the construction cost, There is an effect that the conversion from the mode to the aeration mode or from the aeration mode to the land mode can be performed quickly and easily.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view of an amphibious bus according to an embodiment of the present invention, FIG. 2 is a front sectional view of an amphibian according to an embodiment of the present invention, and FIG. 3 is a cross- Of FIG.

As shown in Figs. 1 to 3, an amphibious bus 1 according to an embodiment of the present invention includes an engine 10, an airstream propulsion device 20, an onshore propulsion devices 31 and 32, The first and second clutches 51 and 52, the ballast tank 61, the aeration tank 72, and the control unit (not shown).

Hereinafter, the amphibious bus 1 according to the embodiment of the present invention will be described with reference to FIG. 1 to FIG.

Before describing the amphibious bus 1, a hull (not shown) is described.

The amphibious bus 1 may be formed in the shape of a ship or in a variety of streamlines, though it is not limited thereto.

The hull may be constituted by a stern section 1a, a central section 1b and a bow section 1c and the stern section 1a may be provided with an engine 10, a water propulsion apparatus 20, A seat S on which a passenger (not shown) is seated is arranged in the inside and a ballast tank 61 and an onshore propelling device 31 or 32 are arranged on the lower side. And a water detection tank 72 may be disposed on the lower side.

Hereinafter, various equipments provided on the hull of the amphibious bus 1 will be described in detail.

The engine 10 generates power for propelling the hull.

Specifically, the engine 10 is disposed in the stern section 1a of the hull, and may be an internal combustion engine for a vehicle provided in the vehicle or a small-sized marine engine provided on the ship to generate power.

At this time, the engine 10 may be connected to the water-pumping propulsion device 20 by a first drive shaft 41, and may be connected by a second drive shaft 42 to the on-land propulsion devices 31 and 32.

The water propulsion device 20 receives power from the engine 10 and propels the hull from the water.

Specifically, the water-propulsion unit 20 is vertically disposed on the engine 10 and can be connected to the first drive shaft 41. The power supplied from the engine 10 is converted into a rotational force to propel the hull from the water .

The water propulsion device 20 may be formed to protrude to a length smaller than the protruded length of the land propelling devices 31 and 32. This makes it possible to drive the water-pumping apparatus 20 even when the water-pumping apparatus 20 is not driven in the ground mode.

In addition, the water-pumping propulsion device 20 may be formed in a form that can be changed to be drawn into the inside of the ship or protruded to the outside. This allows the water-propulsion device 20 to be drawn into the hull in the terrestrial mode, and the water-propulsion device 20 to be drawn out of the hull in the aquam mode, thereby reducing the air resistance in the terrestrial mode .

The water propulsion device 20 can be, for example, a screw propeller, and can be formed in pairs.

The onshore propulsion devices (31, 32) receive the power from the engine (10) and propel the hull on land.

Specifically, the on-land propulsion devices 31 and 32 may be constituted by a rear wheel 31 and a front wheel 32 in the form of wheels, and may be disposed in front of the engine 10 and connected via a second drive shaft 42 And the power supplied from the engine 10 can be converted into rotational force to propel the hull on the land.

At this time, of the land propulsion units 31 and 32, only the rear wheel 31 can be connected to the engine 10 through the second drive shaft 42. [

The land propulsion devices 31 and 32 may be formed to protrude to a length longer than the protruded length of the water propulsion device 20. [ This makes it possible to drive the water-pumping apparatus 20 even when the water-pumping apparatus 20 is not driven in the ground mode.

The first and second drive shafts 41 and 42 connect the engine 10 and the water propulsion device 20 or the on-land propulsion devices 31 and 32 to transmit the power transmitted from the engine 10 to the water- 20) or on-land propulsion units (31, 32).

Specifically, the first drive shaft 41 connects the engine 10 and the water propulsion device 20 and can directly transmit the power transmitted from the engine 10 to the water propulsion device 20, and the first drive shaft 41 The first clutch 51 may be provided.

The second drive shaft 42 connects the engine 10 and the on-land propulsion devices 31 and 32 and can directly transmit the power transmitted from the engine 10 to the on-land propulsion devices 31 and 32, And the second clutch 52 may be provided on the first clutch 42.

The first and second clutches 51 and 52 control whether the first and second drive shafts 41 and 42 are driven.

Specifically, the first clutch 51 is formed on the first drive shaft 51, and may be connected to the control unit by wire or wirelessly, so that the control signal from the control unit may be received by wire or wireless and may be coupled or disassembled.

When the first clutch 51 is engaged and the first drive shaft 41 is connected to the water-propulsion apparatus 20 and the first clutch 51 is disengaged, the first drive shaft 41 is connected to the engine 10 and the water propulsion device 20 are released.

The second clutch 52 is formed on the second drive shaft 42 and may be connected to the control unit by wire or wirelessly, and may receive the control signal from the control unit by wire or wirelessly, and may be coupled or disassembled.

When the second clutch 52 is engaged and the second drive shaft 42 is connected to the engine 10 and the land propulsion units 31 and 32 and the second clutch 52 is disengaged, The engine 10 and the land propulsion devices 31 and 32 are released.

The ballast tank 61 is disposed on the lower side of the hull, and the ballast water can be stored in order to cope with a change in weight due to an increase or decrease of passengers inside the hull.

The ballast tank 61 can be supplied with seawater or fresh water from a sea chest (not shown) formed separately on the lower side of the hull. To this end, the amphibious bus of the present invention has a separate pump .

The water detection tank 72 is formed so as to be able to receive fluid inside the hull.

Specifically, the water-sensing tank 72 can be disposed in the front lower portion of the ship so that the fluid can flow into the ship by the progress of the hull, and the inflow hole H1 through which the fluid is introduced is formed at the frontmost lowermost portion, The outflow hole H2 may be formed on the lower side. At this time, the inlet hole H1 may be formed so as to observe the traveling direction of the hull.

Accordingly, the amphibious bus 1 according to the embodiment of the present invention can promptly determine whether the water-sensing tank 72 is disposed in front of the ship and whether it is an award or a land. That is, since the fluid flows in the direction of travel in the water phase due to the direction of travel of the amphibious bus 1, it can be promptly determined whether it is water or land by arranging it in front of the hull which is the first flow-

In addition, the inflow hole H1 is disposed at the lowermost side in front of the water sensing tank 72, thereby preventing errors in determination of the level of the remaining fluid.

When the inflow hole H1 is disposed at the forward middle or front upper side of the aeration sensing tank 72 without being disposed at the lowermost front side of the aeration sensing tank 72, , The time taken for the fluid flowing from the water phase to remain on the ground during the mode conversion becomes longer, and the transition from the water mode to the land mode may be delayed.

In order to solve this problem, according to the present invention, the inflow hole H1 is disposed at the lowermost position of the front side of the water detection tank 72 to quickly discharge the remaining fluid, thereby preventing the delay in mode switching .

The water detection tank 72 may further include a detection sensor 71 for measuring the level of the fluid contained therein. The detection sensor 71 may be connected to the control unit by wire or wirelessly to measure the level of the fluid contained in the aeration detection tank 72 in real time and transmit the level information to the control unit.

The water detection tank 72 has an effect that the outflow hole H2 is disposed at the lowermost side of the water detection tank 72 so that the fluid can be quickly discharged when the water is converted from the water mode to the land mode. Of course, the inflow hole H1 is disposed at the lowermost position in the forward direction, and the fluid remaining together with the outflow hole H2 can be completely removed, thereby making it possible to prevent an error in determining the level of the remaining fluid.

The control unit receives the level information of the fluid received in the aeration detection tank 72 and controls the first and second clutches 51 and 52 so as to select the drive of the water propulsion device 20 or the land propulsion devices 31 and 32 .

Specifically, when the water level sensed by the water-sensing tank 72 is equal to or higher than the predetermined water level, the control unit controls the first clutch 51 and the second clutch 52 so that the power generated by the engine 10 And when the water level sensed by the water sensing tank 72 is lower than the predetermined level, the first clutch 51 is disengaged and the second clutch 52 is engaged to engage the engine 10, So that the power generated in the on-land propulsion units 31 and 32 is transmitted only.

More specifically, the control unit receives the fluid level of the fluid in the water sensing tank 72 from the sensing sensor 71 of the water sensing tank 72 by wire or wireless, and when the fluid level of the fluid received is above the predetermined level, The engine 10 and the water propulsion device 20 are connected to each other and the engine 10 is connected to the first clutch 51 via a wire or wireless connection, And the land propulsion devices 31 and 32 are released, so that the power generated in the engine 10 can be controlled to be transmitted only to the water propulsion device 20.

When the level of the delivered fluid is less than the preset level, the control unit transmits a release signal to the first clutch 51 by wire or wireless, and transmits the release signal to the second clutch 52 by wire or wireless, The engine 10 and the water propulsion device 20 are disengaged and the engine 10 and the on-land propulsion devices 31 and 32 are connected to each other so that the power generated by the engine 10 is transmitted only to the land propulsion devices 31 and 32 To be transmitted.

Accordingly, the amphibious bus 1 according to the embodiment of the present invention detects whether the position of the amphibious bus 1 is a prize or a terrestrial through the water level of the aquametage tank 72, It is possible to automatically convert to the airstream mode in the land mode or the land mode, thereby enabling smooth amphibious traffic.

In addition, since the rolling of the wheels in the land mode can be realized through the one engine 10 and the first and second clutches 51 and 52 and the screw rotation in the airstream mode can be implemented, the construction cost can be reduced, To the aquatic mode or from the aquatic mode to the athletic mode can be quickly and easily achieved.

In addition, in the embodiment of the present invention, an alarm unit (not shown) may be further provided for alarming the user U boarding on the hull, whether an aquatic or terrestrial mode switchover is possible.

The control unit receives the fluid level of the fluid in the water sensing tank 72 from the sensing sensor 71 by wire or wireless and compares it with the predetermined water level. If the fluid level is higher than the reference water level of the water level sensing tank 72 Is within 5% of the upper and lower range, the alarm unit can be operated.

The amphibious bus 1 according to the embodiment of the present invention sets the error judgment range within a range of 5% or less of the predetermined water level without depending only on the predetermined water level, (U) to detect whether the water level or the ground level is present by allowing the user U to make an intuitive judgment by placing an alarm part in the water level sensor There is an effect of preventing misjudgment.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification and the modification are possible.
