DETAILED DESCRIPTION OF THE EMBODIMENTS

As shown inFIG. 1, as a vehicle travels at a high velocity, it knocks into an air resistance wall711, and a reacting force forms an air resistance hole712firmly surrounding the vehicle. The faster the vehicle travels, the thicker the air resistance wall711and the air resistance hole712will be, and the higher the resistance will be. A first pressure region713is formed between the back of the vehicle and an air resistance hole entrance714, and brings pressure resistance to the vehicle. The faster the vehicle travels, the higher the pressure resistance will be, and the larger an area of the first pressure region713will be. Once the air resistance hole entrance714is closed, large air pressure is generated between inside of the air resistance hole712and outside thereof, and a second pressure region715is formed by the air resistance wall711, the air resistance hole712, and the air resistance hole entrance714, which greatly increase energy consumption of the vehicle. Therefore, to prevent the air resistance hole entrance714from being closed is a key point of reducing energy consumption. In this embodiment, the second pressure region715is significantly larger than the first pressure region713.

As shown inFIG. 2, an energy-saving vehicle of a first embodiment of the invention comprises a housing comprising an outer portion2and an inner portion3, an air-flow channel4, a first air inlet7, an air outlet8. The first air inlet7is disposed in the front of the vehicle, the air outlet8is disposed at the back of the vehicle, and the air-flow channel4is disposed between the outer portion2and the inner portion3of the housing and connected to the air outlet8. In this embodiment, the air-flow channel4is annular.

A rotating head9is disposed in the first air inlet7and driven by a motor901. At least a third air inlet701is disposed around the vehicle and connected to the air-flow channel4. A spoiler201in the shape of a concave-convex parabola is disposed at the bottom of the outer portion2, and at least a second air inlet702is disposed on the spoiler201. In this embodiment, the rotating head9is in the shape of a disk.

As the vehicle travels at a high velocity, it knocks into the air resistance wall711. At this time, the rotating head9rotates at a high speed, disperses resistance of the air resistance wall711under centrifugal force, and enables the resistance to enter the air-flow channel4, whereby preventing collision between the air and the inner portion3and reducing resistance of the air resistance wall711.

Since air resistance is proportional to a cross section of a windward side of the vehicle, the first air inlet7having an area approximately or complete the same as that of a front portion of said housing induces air of a collision surface between the air resistance wall711and the housing into the air-flow channel4, whereby reducing resistance of the air resistance wall711and pressure resistance of the second pressure region715.

Then, air of the air resistance wall711around the first air inlet7forms the air resistance hole712and firmly surrounds the vehicle. Meanwhile, since the spoiler201in the shape of a concave-convex parabola is disposed at the bottom of the outer portion2, a length of a path of the air passing through the spoiler201is larger than that of an upper portion of the housing, air passing through an inner surface and an outer surface of the spoiler201has an increased speed, and speed of air in the air-flow channel4is greater than that in an normal condition, and therefore speed of the air in the air-flow channel4is greater than that outside the air-flow channel4. The second air inlet702induces air at the bottom of the spoiler201into the air-flow channel4, which balances speeds of air in and outside the air-flow channel4. A length of a path of the air passing through the spoiler201is no less than that of an upper portion of the housing, whereby reducing or eliminating lifting force.

The air resistance hole712firmly surrounding the vehicle is formed by lateral resistance, namely pressure applied to the vehicle by air around the vehicle. Under the pressure, air closely adjacent to an upper portion of the housing of the vehicle is squeezed into the air-flow channel4via the first air inlet701.

If resistance of the air resistance wall711and the air resistance hole712is reduced, air of the air resistance hole712simultaneously reaches the back of the vehicle from all around whereby obtaining good continuity. If the air resistance hole entrance714is closed, the vehicle is greatly affected by the second pressure region715formed by the air resistance wall711, the air resistance hole712, and the air resistance hole entrance714and travels with great difficulty. As too much air from the air resistance wall711is induced via the first air inlet7, pressure resistance of the second pressure region715is greatly reduced, and at the same time, large quantity of air with a speed higher than the vehicle is emitted from the air outlet8, which makes it impossible to close the air resistance hole entrance714. If air in the first pressure region713is enough, the first pressure region713and the second pressure region715will disappear and the pressure region at the back of the vehicle is turned into air with a forward direction. Since large quantity of air is induced into the air-flow channel4via the first air inlet7, the second air inlet702and the third air inlet701, multiple pressure regions are formed therein or somewhere in the vicinity thereof and uniformly distributed thereon, which causes large quantity of air on the surface of the housing is induced into the air-flow channel4via the first air inlet7, the second air inlet702and the third air inlet701. And thus pressure regions are formed and are positive air pressure regions. Since distribution of air is changed, reduction of energy consumption is implemented.

A flexible sleeve801is used to adjust a spraying angle of the air outlet8, whereby closing the air resistance hole as the vehicle travels at different speeds.

As shown inFIGS. 3-5, an energy-saving vehicle of a second embodiment of the invention comprises a housing comprising an outer portion2and an inner portion3, an air-flow channel4, an airflow hole5, a first air inlet7, and an air outlet8. The air-flow channel4is disposed between the outer portion2and the inner portion3of the housing. In this embodiment, the air-flow channel4is circular. The airflow hole5can be regarded as a bottom air-flow channel that has a same width as the housing. The bottom air-flow channel is divided into three independent sub-air-flow channels by two spoilers403, and thus four sub-air-flow channels are formed. The first air inlet7, a middle air-flow channel404and the air outlet8are sequentially connected. A left air inlet7, an air-flow channel402and a rear air outlet801are sequentially connected. A right air inlet7, an air-flow channel401and a rear air outlet802are sequentially connected.

At least a third air inlet701is disposed in the vicinity of the housing and connected to the air-flow channel4and a middle air outlet803.

At least a second air inlet702is disposed at the bottom of the outer portion2. Bottom air-flow channels404,401and402are divided by the spoilers403between the outer portion2and the inner portion3, and thus three independent air layers are formed.

Alternatively, the bottom air-flow channels404,401and402may be not completely separated by the spoiler403, and form a huge air layer. The air outlet8is disposed in the middle of the bottom at the back of the vehicle, the air outlet803is disposed above the air outlet8, and the air outlets801and802are disposed at the back of the air outlet8.

As the vehicle travels at a high velocity, it knocks into the air resistance wall, and resistance of air resistance wall is induced into the air-flow channels404,402and401via the first air inlet7having an area approximately or completely the same as that of a front portion of the housing, a decorative window703, and a vehicle headlight705. Both sides of the decorative window703and the vehicle headlight705are in the shape of a stream line whereby reducing air resistance.

Vertical air resistance on a windshield of the vehicle is not reduced, and a pressure region is formed on a front air inlet. Under inward pressure, the third air inlet701on one side or at the top of the vehicle induces part of air resistance from the air resistance hole in to the air-flow channel4, whereby reducing part of resistance from the air resistance wall and the air resistance hole.

The air-flow channel can employs different shapes, and a cross section thereof may be in the shape of an ellipse, a circle, a rectangle, a snake, a loop or a stream line, so that a length of a path of air passing the bottom of the vehicle is no less than that of an upper portion of the housing. In this embodiment, the air-flow channel has a concave-convex surface, and a length of a path of air passing the air-flow channel is no less than that of an upper portion of the housing, and therefore a speed of the air is increased. Moreover, since under the same condition, air speed in the air-flow channel is higher than that in a normal condition (namely a vehicle speed), the second air inlet702is disposed between the bottom of the vehicle and the air-flow channel, and an opening state is formed. At this time air speed at the bottom of the vehicle is lower than that of an upper portion of the vehicle, air at the bottom of the vehicle is induced into the air-flow channels404,402and401via the second air inlet702, whereby balancing air at the bottom of the vehicle with that in the air-flow channels404,402and401. The air-flow channel402enables a length of a path of air passing the air-flow channels is no less than that of an upper portion of the housing, and therefore lift resistance is reduced or disappeared, and the vehicle travels more safely, stably and economically.

The air inlets spray air of the air resistance wall and the air resistance wall from the air outlets8,801,802and803via the air-flow channels at a speed higher than or equal to the vehicle speed. If there is a large amount of air, the air resistance hole can be used to close air in the air resistance hole entrance, at this time reverse resistance is turned into forward driving force, surrounds the vehicle, fills the pressure region at the back of the vehicle, eliminate pressure resistance, causes pressure resistance at the back to disappear so that a big pressure cannot be formed, and turns the back of the vehicle into a high pressure region.

The inner portion3of the housing is concave, which forms a big airflow hole5having a same width as the housing, increases space in the vehicle and increases air speed in the air-flow channel. The independent air-flow channels404,401and402can also be semi-independent air-flow channels. Decorative windows are disposed on all the air inlets, and vent holes thereof are in the shape of uniformly-distributed bars.

Airflow controllers704are disposed in all the air outlets and the decorative windows703. An upper surface of an airflow controlling plate therein is parabolic, and a bottom thereof is planar whereby increasing an air speed. The airflow controllers704is louver-like and is capable of controlling an angle of spraying and absorbing of air, whereby controlling resistance and lift force generated by different airflow in the air-flow channel4. In emergency cases such as reducing a speed or braking, the air outlet closes the airflow controllers704, large resistance is generated in the air-flow channel by high-speed air, which naturally reduces the vehicle speed, and makes the vehicle travel more safely with the help of a brake.

The vehicle headlights705are disposed on both sides of the outer portion2of the housing.

Alternatively, the airflow controller704is disposed in the decorative window703. A motor804with an adjustable rotating speed is disposed in the air outlet803and operates to spray and absorb air. One end of the motor is connected to the air-flow channel4. As the vehicle travels at a high velocity, the first air inlet7induces air of the air resistance wall into the air-flow channels401,404and402, and then the air is sprayed from the air outlets8,802and801. At this time the motor804absorbs air, and increases the air speed via the airflow controller704in the decorative window703and the air-flow channel4. The airflow controller704is capable of controlling an angle, and both sides thereof are parabolic.

Since the motor804has strong suction power and is capable of quickly absorbing air in the vicinity of the third air inlet701, whereby forming a pressure region in the vicinity thereof and on the outer portion2of the housing.

The resistance of the air resistance hole can be reduced if a motor having low energy consumption is used. And then air having a speed higher than the vehicle speed is sprayed from the air outlet803, which turns the back of the vehicle into a forward driving area. Reaction force generated thereby helps the vehicle to travel at a high velocity. The structure can be used for producing racing cars or sports cars.

If the motor804has a large power, original power of the vehicle can be switched off. This is because that after lift force is eliminated, weight of the vehicle is greatly reduced, at this time, large driving force is not required, and a turbofan engine with small power can be used. The vehicle features low energy consumption with respect to existing vehicles.

Alternatively, the bottom air-flow channel, the air inlet and the air outlet are not used. An air-flow channel4is formed between the outer portion2and the inner portion3and surrounds the vehicle. Air inlets701and702are uniformly distributed around the housing. An airflow controller704is disposed in a decorative window703of the air inlet. One end of a motor804in each of the air inlet and the air outlet803is connected to the air-flow channel. As the vehicle travels at a high velocity, the motor804absorbs air in the vicinity of the air inlets, which reduces resistance of the air resistance wall and the air resistance hole to the minimum and saves energy.

As shown inFIGS. 6 and 7, an energy-saving vehicle of a third embodiment of the invention comprises a housing comprising an outer portion2and an inner portion3, windshield5, a door6, a first air inlet7, an air-flow channel, a pair of first air outlets801and a second air outlet803. The first air outlets801are disposed on both sides of the bottom at the back of the vehicle, and the second air outlet803is disposed at the center of the back of the vehicle. The air-flow channel is formed between the outer portion2and the inner portion3, and comprise a first sub-air-flow channel4and a second sub-air-flow channel401connected to each other. The first sub-air-flow channel4is linear, and the second sub-air-flow channel401is annular.

A rotating head705is disposed at the center of the first air inlet7and driven by a motor706. The rotating head705is in the shape of a cone, a flying plate, a hemisphere, a stream line and so on. The rotating head705generates centrifugal force by rotating at a high speed. Under the centrifugal force, air is induced into the first sub-air-flow channel4, whereby avoiding resistance generated by knocking into forward air resistance and applied on the inner portion3. A contact surface between the rotating head705and the air has concave or convex helix.

Multiple fitting portions are disposed on the vehicle for installing the windshield5and the door6. The door6employs a double-layer hollow structure, and is connected to the air-flow channel via a third air inlet701. The windshield5and the door6are disposed between the first air inlet7and the second sub-air-flow channel401. The door6is connected to the second sub-air-flow channel401via the first air inlet701. Various beautiful vehicles are formed by the second sub-air-flow channel401, the inner portion3, the outer portion2and the door6. Compared with the existing vehicle, the invention is more simple and practical, and greatly reduces production cost. The first air inlet7, the first air outlets801, and the second air outlet803are sequentially connected.

At least a third air inlet701is disposed on both sides and at the top and bottom of the first sub-air-flow channel4and the second sub-air-flow channel401, and a second air inlet702is disposed at the bottom thereof, so that the first sub-air-flow channel4and the second sub-air-flow channel401are connected to the outside. Multiple decorative windows703with different size are disposed on all the air inlets and air outlets according to shapes thereof. The air inlets are disposed in the decorative window703, and in the shape of uniformly-distributed bars, diamonds, square grids, cells, circular holes, stream lines and so on. The air inlet can be fixed, or has an airflow controller704for controlling an angle. The decorative window has smooth surface and fluent lines for decoration, and operates to prevent foreign bodies from entering without affecting absorbing and spraying air. In this embodiment, the first air inlet7and the third air inlet701have the decorative windows and are fixed, and the airflow controller704is disposed in the decorative window703of the second air inlet702.

At least a wind indicator9is disposed in the first sub-air-flow channel4, a rotating axis901is disposed in the wind indicator9, a pair of power generators903is disposed on both ends of the rotating axis901, and an impeller902is disposed on the rotating axis901. The power generator903is capable of recharging no less than one fuel cell904whereby providing an auxiliary power supply. The fuel cell904supplies power to a motor10and drives a speed reducer101to operate.

As the motor10rotates at a low speed, torque thereof is large, and thus the motor10is difficult to operate. By using the speed reducer101, wheels106of the vehicle are capable of rotating freely. The speed reducer101drives a differential gear102to operate, and equally distributes torque from the speed reducer101to a pair of half shafts104. As the vehicle turns or travels on an uneven road, driving wheels on both sides thereof rotate at different speeds. The half shafts104are connected and fixed to a nave boss105in the wheel106. Rotation of the motor10is controlled by a controlling board11, or functions of traditional four-speed gearbox are integrated on the controlling board11, or traditional gearboxes can be used to facilitate these functions without accelerator pedals.

A stepless control button111is disposed on a steering wheel and operates to adjust a rotation speed of the motor10. Operation of the motor10drives the wheels106to rotate (such as forwardly, reversely, slowly and quickly) after transmission. In this invention, there is no accelerator pedal but a brake pedal, which reduces possibilities of traffic accidents.

The speed reducer101, the differential gear102and the half shafts104are normal automobile parts in the art.

As the vehicle travels at a high velocity, since the rotating head705is driven by the motor706, rotates at a high speed, and generates centrifugal force that throws air into the first sub-air-flow channel4. Most resistance of the air resistance wall is induced into the first sub-air-flow channel4via the first air inlet7having an area approximately or completely the same as a front portion of the housing. Alternatively, the area of the first air inlet7is slightly less than that of a front portion of the housing. Vertical air resistance on the windshield cannot be reduced. Under pressure, air of the air resistance hole surrounding the vehicle is induced into the first sub-air-flow channel4and the second sub-air-flow channel401via the third air inlet701and the second air inlet702whereby reducing resistance of the air resistance wall and the air resistance hole. At this time, a length of each of the first sub-air-flow channel4and the second sub-air-flow channel401is larger than that of an upper portion of the vehicle, whereby eliminating lift resistance. Since air speed at the bottom of the vehicle is greater than that at the top thereof, and air pressure at the top of the vehicle stably presses an upper portion of the housing, which makes the vehicle travel more stably, safely and economically.

The air outlet sprays air of the air resistance wall and the air resistance wall from the air inlets in the air-flow channels at a speed higher than the vehicle speed. If there is a large amount of air, reverse air resistance reaching the back of the vehicle and operating to close the air resistance hole entrance surrounds the vehicle, fills the pressure region at the back of the vehicle, causes pressure resistance at the back to disappear, and turns the pressure region into a high pressure region.

A removable head802on the air outlet8controls two bottom air outlets801and a middle air outlet803to spray air in a desired direction. Since a length of a path of the air passing through the air-flow channel is far larger than that of an upper portion of the housing, the decorative window703operating to control an angle of the airflow controller704is disposed in the second air inlet702, and operates to control incoming air of the bottom air-flow channel and solve a problem of large pressure at the top of the vehicle after lift force is eliminated.

As shown inFIG. 8, difference between an energy-saving vehicle of a fourth embodiment of the invention and that of the third embodiment is, the second sub-air-flow channel401is an annular hole, and a pair of motors804are disposed in the air outlets801at the bottom of both sides of the vehicle. The motor804can operate after the airflow controller disposed in the decorative window703closes the air outlet803.

As the vehicle travels at a high velocity, since the motor804has strong suction power and is capable of quickly absorbing air in the vicinity of the air inlets, a pressure region is formed in the vicinity thereof and in the front and on the surface of the housing, which reduces resistance of the air resistance wall and the air resistance hole. Since a length of a path of the air passing through the first sub-air-flow channel and the second sub-air-flow channel is far larger than that of an upper portion of the housing, the lift resistance disappears, and the vehicle travels more stably, safely and economically. Air sprayed from the air outlet has a speed higher than the vehicle speed, and instantly fills the pressure region at the back of the vehicle, which causes a low pressure region to disappear and a high pressure region not to be formed, and turns the back of the vehicle into a forward driving area.

The resistance of the air resistance hole can be reduced if a motor having low energy consumption is used. And then air having a speed higher than the vehicle speed is sprayed from the air outlet803, which turns the back of the vehicle into a forward driving area. Reaction force generated thereby helps the vehicle to travel at a high velocity. The structure can be used for producing racing cars or sports cars.

A main body of the vehicle is formed by the outer portion2and the inner portion3that are curved. If borders of the outer portion2and the inner portion3are made of metal materials, they will be more firm. The outer portion2and the inner portion3are made of engineering plastics or light-weight materials such as carbon fibers and fiber glass, which reduces light of the vehicle and guarantees strength thereof. The windshield5is disposed in the annular hole. A foldable roof602can be folded or unfolded via controlling, which forms a novel, simple, light-weight, safe and reliable racing car or a sports car. The third air inlet701, the second air inlet702and the air outlet803each has a decorative window703with an airflow controller. Strong suction power generated by the motor804increases air speed in the air-flow channel and the air inlets, and then air is sprayed from the air outlet at a speed higher than the vehicle speed. The air having a speed far higher than the vehicle speed instantly fills a pressure region at the back of the vehicle, and large reaction force is generated and helps the vehicle to travel. If the motor804has a large power, original power of the vehicle can be switched off and the motor804provides power. Alternatively, the motor804is not used and the air outlets801and803naturally exhaust gas, at this time, the invention is a good racing car or a sports car with good performance.

As shown inFIGS. 9 and 10, an energy-saving vehicle of a fifth embodiment of the invention is illustrated. A control board906is disposed on an instrument penal of the vehicle1. A speed controlling button907is disposed on a steering wheel and operates to control a stepless control button to control a speed of the motor. There is only a brake pedal below feet of a driver, which prevents traffic accidents usually caused by erroneous operation of accelerator pedals and the brake pedals and guarantees safety of travelling.

The vehicle1comprises a housing comprising an outer portion2and an inner portion3, and an air-flow channel4is formed between the outer portion2and the inner portion3. A first air inlet7having an area approximately or completely the same as a front portion of the housing is disposed in the front of the outer portion2. A decorative window703is disposed on the first air inlet7. Multiple vent holes in the shape of square grids are disposed in the decorative window703and operate as ornaments for filtering impurities in air.

The first air inlet7receives air of an air resistance wall as the vehicle travels. The air is induced into the air-flow channel4via the first air inlet7. At this time the air resistance hole tightly surrounds the housing of the vehicle and generates another resistance. At least a third air inlet701and a second air inlet702are disposed at the top and on one side of the vehicle and provide outlets for the air resistance hole. Under inward pressure, part of the air is induced into the air-flow channel4, whereby reducing resistance of the air resistance wall and the air resistance hole.

A spoiler201is disposed at the bottom of the outer portion2, and connected to the air-flow channel4via at least one first air inlet702, whereby increasing air speed at the bottom of the vehicle and a length of a path of air passing through the air-flow channel.

A surface of a spoiler201is in the shape of concave-convex stream line whereby increasing a length of air passing through the spoiler201. Since a speed of the air passing through the spoiler201is greater than a plane, speed of the air passing through the bottom of the vehicle is increased. Moreover, since a length of a path of the air passing through the spoiler201is greater than that of an upper portion of the housing, lift resistance disappears. Then the air-flow channel transfers air induced from all air inlets to the air outlet8at the back of the housing2, and the air is sprayed from the air outlet801at a high speed. A decorative window703is disposed in the air outlet8and operates to control an airflow controller. If there is a large amount of air, the air fills a low pressure region at the back of the vehicle, a big pressure cannot be formed, the back of the vehicle is turned into a high pressure region, and resistance as the vehicle travels is reduced.

As for the vehicle of the invention, air pressure at the bottom of the vehicle is slightly less than that at the top thereof, and the air pressure at the top stably presses the upper portion of the housing. Under a same speed and size, the vehicle of the invention is more stable, safe and economical than a vehicle of 2 tons. Since weight of the vehicle is not taken into account so as to overcome air resistance, a weight of the vehicle of the invention is greatly reduced. Light-weight and firm materials are used as a body, and an overall weight of the vehicle is 350 Kg, including weight of a gas storage device and gas. Namely, the weight of the invention is only ⅕ than that of a normal car which is 1.3-2 tons, and energy is saved by approximately 80%. Moreover, since materials for producing the vehicle are saved by 80% in weight, production cost is greatly reduced.

The vehicle of the invention further comprises an air motor operating to drive wheels. Airflow control of the air motor is implemented by a multi-way electromagnetic valve whereby driving the vehicle to travel. A main gas-storage device5is disposed in the front of the vehicle1, and an auxiliary gas-storage device501is disposed at the back thereof, a gas inlet502is disposed on each of the main gas-storage device5and the auxiliary gas-storage device501and makes it possible to inject gas therein. A barometer503is disposed on each of the main gas-storage device5and the auxiliary gas-storage device501and makes it possible to observe a pressure state thereof. A pressure regulating valve504is connected to a gas outlet of each of the main gas-storage device5and the auxiliary gas-storage device501and operates to adjust gas pressure of compressed gas therefrom. A flowvalve505is connected to the pressure regulating valve504. A multi-way valve506is connected to the flowvalve505. Each way of the multi-way valve506can be independently switched on or off via controlling and connected to the air motor603via a pipe507. The multi-way valve506connected to the flowvalve505of the main gas-storage device5is a five-way electromagnetic valve, and four ways thereof are connected to the air motors603on four wheels. The multi-way valve506connected to the flowvalve505of the auxiliary gas-storage device501is a three-way electromagnetic valve, and two ways thereof are connected to the air motor603on two rear wheels. The pipe507induces compressed air in and drives the air motor603. A rotating shaft602of the air motor603is fixed to a nave boss601via a speed reducer604, whereby forcing the driving wheel6to rotate.

At least a wind indicator9is disposed in the air-flow channel4between the first air inlet7and the air outlet8. As the vehicle travels, air enters the air-flow channel4and drives an impeller902and a rotating shaft901. A pair of generators903(or air pumps) are connected to both ends of the rotating shaft901. Electric energy produced by the generator903is stored in at least a fuel cell904, or directly used to drive an air compressor905to inflate for the main gas storage device5. The full cell904supplies power for devices in the vehicle, such as lights, audio devices and control circuit boards906.

In this embodiment, four-wheel drive is implemented by the air motor603. Alternatively, the front wheels, the rear wheels or only one wheel is driven by the air motor603, which makes the invention convenient for use on crowded roads and during parking. Moreover, the motor10inFIGS. 6 and 7can be replaced by the air motor603whereby driving the front wheels or the rear wheels, or the full cell can be used to drive the air pump905to store gas for the gas storage device whereby driving the air motor603. Alternatively, the air motor603can be replaced by an electric motor powered by the fuel cell.

The vehicle of this embodiment makes use of compressed air that is an inexhaustible energy. However, since the gas storage device has a large size and dynamic energy generated by the compressed air is limited, the following requirements should be met: 1) the body of the vehicle is light and safe; 2) the compressed air should be effectively used. Since the invention is capable of eliminating the lift resistance and the overall weight of the vehicle is approximately 350 Kg, the air motor directly drives all the wheels and a transmission process is greatly simplified. Therefore, as long as design is reasonable, the simpler the vehicle is, the more reliable it will be, and the less failure rate it will have, and energy waste caused by injecting the compressed air in an engine for driving the transmission system is prevented. Moreover, the wind indicator is capable of supplying power to the vehicle as the vehicle travels, and therefore production of a vehicle driven by the compressed air or the fuel cell is feasible.

As shown inFIG. 11, an energy-saving double-deck vehicle of a sixth embodiment of the invention comprises a housing comprising an outer portion2and an inner portion3, and an air-flow channel4is formed between the outer portion2and the inner portion3. The air-flow channel4surrounds an upper compartment and a lower compartment. An upper air-flow channel401, a middle air-flow channel402and a lower air-flow channel403are respectively connected to a first air inlet7and a pair of air outlets802and801. The air outlets802and801are disposed at the back of the vehicle and each has a same width as the housing. At least a wind indicator901is disposed in the air-flow channel4and driven by air whereby forcing an impeller902to rotate to drive a generator903. Power generated by the generator903recharges a battery904operating as an auxiliary power supply.

As the double-deck vehicle travels at a high velocity, a pair of motors705are disposed at the bottom and the top of the first air inlet7, and operate to drive a rotating head704to operate at a high speed whereby generating centrifugal force to throw vertical air resistance into the air-flow channel, preventing crash between the air and the inner portion3, and reducing vertical resistance of the air resistance wall. The first air inlet7having an area approximately or completely the same as that of a front portion of the housing induces the air resistance wall in the air-flow channels4,401,402and403. Multiple strip-shaped decorative windows703are disposed on at least one of the second air inlet702and the third air inlet701, whereby inducing part of air of the air resistance hole firmly surrounding the housing in the air-flow channels4,401,402and403. At this time, under pressure, air resistance holes in the vicinity of the air inlets and firmly surround the housing are pushed into the air inlet, and air of vertical and lateral air resistance wall and air resistance hole is induced into the air-flow channel, which causes large amount of air uniformly distributed on and in the vicinity of the air inlet is induced and form a pressure region at the surface of the housing. The first air-flow channel403is connected to the first air inlet7, and the annular hole404is connected to the air outlet8.

As air passes the bottom air-flow channel403and the annular404, a length of the air passing through the bottom air-flow channel403and the annular404is larger than that of an upper portion of the housing, and an air speed is higher than that at the top of the vehicle. At this time lift resistance is eliminated, air pressure at the top of the vehicle stably presses the upper portion of the housing, and thus the vehicle travels more quickly, stably, safely and economically. The air-flow channel sprays air of the air resistance wall, the air resistance hole and at the bottom of the vehicle from the air outlets802.801and8at a speed higher than an air speed at the top of the vehicle. A removable head804can be used to change an angle of spraying whereby forcing air of the air resistance hole to reach the back of the vehicle simultaneously for continuity of air, to close the air resistance hole entrance, and to surround the air sprayed from the air outlet. The gas instantly fills a pressure region at the back of the vehicle, and causes a low pressure region at the back thereof to disappear and a big pressure not to be formed.

Since air distribution of the double-deck vehicle is changed, lift resistance is eliminated and pressure at the top of the vehicle is larger than that at the bottom thereof. Therefore the vehicle does not need to overcome lift resistance by increasing a weight thereof, which decreases weight of the vehicle, improves holding capacity, and makes the vehicle travel more stably, safely and economically. The double-deck vehicle can travel in cities, or operates as a long-distance bus featuring improved transport capacity. The principle of the invention can be applied to a double-deck train, in which the air inlet and the air outlet are connected to different carriages via the air-flow channel, and thus transport capacity thereof is greatly improved and transport cost is reduced. The principle of the invention can be applied to a single-deck train, subways, large buses and large juggernauts.

As shown inFIG. 12, an energy-saving vehicle of a seventh embodiment of the invention comprises a first air inlet7, an air outlet8, and an air-flow channel4. The first air inlet7is disposed in the front of the vehicle1, and the air outlet8is disposed at the back of the vehicle and connected to the first air inlet7via the air-flow channel4. A decorative window707is disposed in the first air inlet7, and multiple vent holes in the shape of a diamond are disposed therein, whereby enabling air to freely pass through without hindrance and preventing foreign bodies from entering. A decorative window708is disposed in the air outlet8, and an airflow controller is disposed therein. Opening or closing, and an angle of the air outlet8can be controlled via the airflow controller. In emergency cases such as reducing a speed or braking, the airflow controllers in the decorative window708is closed, large resistance is generated in the air-flow channel since large amount of air cannot be discharged from the air outlet8, which naturally reduces the vehicle speed, and makes the vehicle travel more safely with the help of a brake.

As the vehicle travels at a high velocity, a first air inlet7having an area approximately or completely the same as a front portion of the housing induces air of the air resistance wall in the air-flow channel4and sprays the air from the air outlet8, and the air instantly fills the pressure region at the back of the vehicle, which causes a high pressure region not to be formed, turns the back of the vehicle into a forward driving area, and reduces energy consumption of the vehicle.

An inflating device is disposed at the bottom of the housing. A rectangular air cushion401is formed after being inflated by an air pump via a pipe202, and reduces a distance between a road and a bottom404of the air cushion, whereby preventing obstacle on the road from affecting the vehicle and making the vehicle travel more conveniently. Moreover, air passing the bottom of the vehicle is greatly decreased, which further reduces air resistance and lift resistance. As road condition is poor or the air cushion401is to be folded, it is deflated via a deflating vent201, and then at least a reset spring203disposed at the bottom thereof upwardly folds the air cushion401and attaches the cushion401to the outer portion2of the housing. A hand air pump can be used by the deflating vent201to inflate the air cushion401. A light-weighted sheet402is disposed in the bottom404of the air cushion, and the bottom404of the air cushion is formed by soft materials such as leather, soft plastics, cloths, rubbers and so on. One side of a sealing frame403is connected to the outer portion2, and the other side thereof is connected to the bottom404of the air cushion whereby forming multiple air cushions401,403and404. Alternatively, the bottom404can be replaced by a concave-convex spoiler.

As shown inFIG. 13, the air cushion401can be designed to have different areas and separately disposed at the bottom of the vehicle.

Alternatively, an air cushion401having a same area as the bottom of the vehicle can be used. An air outlet405is disposed at the center of the bottom404of the air cushion401and operates to discharge air generated by an engine in the front of the vehicle to the ground. A vertical plane or a horizontal plane of the bottom404is concave-convex, which increases an air speed. Or the air cushion401is disposed at a first half part or a second half part at the bottom of the vehicle.

As shown inFIG. 14, an energy-saving vehicle of an eighth embodiment of the invention comprises a first air inlet7, an air outlet8, and an air-flow channel4. The first air inlet7is disposed in the front of the vehicle, and the air outlet8is disposed at the back of the vehicle and connected to the first air inlet7via the air-flow channel4. A decorative window802is disposed in the air outlet8, and an airflow controller is disposed therein. Airflow and an angle of the air outlet8can be controlled via the airflow controller, whereby controlling airflow in the air-flow channel4and resistance and lift resistance generated by the airflow. In emergency cases such as reducing a speed or braking, the decorative window802is closed, large resistance is generated by high-speed air in the air-flow channel, which naturally reduces the vehicle speed, and makes the vehicle travel more safely with the help of a brake. The air-flow channel4is connected to an engine room302via a first air inlet703. An arc-shaped plate301can be sued to separate the engine room302. At least a third air inlet701at the top and on both sides of the vehicle is connected to the engine room301, and a second air inlet702is connected to the air-flow channel4.

As the vehicle travels at a high velocity, since the outer portion2is a concave-convex spoiler201, and a path of air passing through inside and outside of the spoiler201is larger than that of an upper portion of the housing, lift resistance is eliminated.

The first air inlet7having an area approximately or completely the same as a front portion of the housing induces air of the air resistance wall in the parabolic concave-convex air-flow channel4, but vertical resistance on a windshield is not reduced. At least a third air inlet701at the top of the vehicle and a first air inlet703on one side thereof induce part of the air in the engine room302whereby dissipating heat from a water tank and an engine, and then the air is induced tin the air-flow channel4via the first air inlet703. Air at the bottom of the vehicle is induced in the air-flow channel4via the second air inlet702whereby balancing air in the outer portion2with that outside the outer portion2. The air-flow channel4induces air from all the air inlets in the decorative window802of the airflow controller and then the air is sprayed from the air outlet8, whereby turning the back of the vehicle into a high pressure region and reduces energy consumption of the vehicle.

As can be seen that as long as the spoiler201is added to the bottom of the vehicle whereby forming the air-flow channel4between the spoiler201and the bottom thereof, a length of a path of air passing the air-flow channel4is greater than that of the upper portion of the housing and lift resistance disappears. Especially, since air resistance is proportional to a cross section of a windward side of the vehicle, and the windward side is an air inlet having an area approximately or completely the same as the housing, vertical resistance is turned into friction force on the air-flow channel and resistance of a vertical air resistance wall is greatly reduced. A separating plate can be added to the bottom of the vehicle whereby forming an air inlet and an air outlet connected to the air-flow channel4, which improves holding capacity and safety of the vehicle and reduces resistance and energy consumption thereof. The spoiler201can form the air-flow channel4via a plane.

As shown inFIGS. 15 and 16, difference between an energy-saving vehicle of a ninth embodiment of the invention and that of the eighth embodiment is, a concave-convex spoiler202is added to the air-flow channel4whereby forming two air-flow channels401and4. The first air inlet7is connected to the air-flow channel4and the air outlet8. The first air inlet7is connected to the air-flow channel401and the air outlet801. One end of a removable rod204is fixed to the inner portion3of the housing, and the other end thereof is fixed to the spoiler201. The removable rod204can be stretched or contracted via control such as hydraulic pressure, air pressure and electromotive action. Multiple removable rods204that are reasonably arranged are capable of forcing the spoiler201to move upwards or downwards. Alternatively, the removable rod204is not used and the spoiler201moves upwards or downwards via mechanical control, which is well-known in the art. A sealing plate203is disposed in the vicinity of the air-flow channel4. The bottom of the sealing plate203is connected to the spoiler201, and the top thereof is disposed in a removable groove205in a frame207at the bottom of the vehicle. A rubber ring206is disposed in the removable groove205and operates to seals the air-flow channel4as the sealing plate203passes the rubber ring206. The sealing plate203can be moved upwards or downwards within a certain distance whereby increasing or reducing a distance between the spoiler201and the road. As the spoiler201moves downwards, the distance between the spoiler201and the road is reduced, air is reduced and traveling of the vehicle is not affected. As a road condition is poor, the spoiler201moves upwards, the distance between the spoiler201and the road is increased and the vehicle is capable of traveling normally.

As the vehicle travels at a high velocity, the movable rod204moves the spoiler201downwards whereby reducing the distance between the spoiler201and the road, at this time the air entering the bottom of the vehicle is reduced, which increases a speed of the vehicle, reduces air resistance, and eliminates lift resistance.

As the vehicle travels at a high velocity, the first air inlet7having an area approximately or completely the same as a front portion of the housing induces air of the air resistance wall in the air-flow channels4and401, and the third air inlet701induces part of air at the top and on one side of the vehicle in the engine room302. Meanwhile, the first air inlet7induces part of air in the air-flow channel4, and the second air inlet702induces air in the air-flow channel4. The air-flow channels4and401formed by spoilers201and202cause a length of a path of air passing therethrough to be greater than that of an upper portion of the housing whereby eliminating the lift resistance, and then spray the air from the air outlets8and801. The air instantly fills a pressure region at the back of the vehicle, eliminates pressure resistance, and turns the back of the vehicle into a high pressure region.

Multiple decorative windows703are disposed on all air inlets and the air outlet.

For the energy-saving vehicle of the invention, it comprises a housing comprising an inner portion and an outer portion, at least an air-flow channel, at least a first air inlet, and at least an air outlet. There is a certain distance between the inner portion and the outer portion of the housing. The air-flow channel is formed between the inner portion and the outer portion of the housing. The first air inlet is disposed in the front of the housing, and the air outlet is disposed at the back of the housing. The first air inlet, the air outlet and the air-flow channel are connected. At least a third air inlet is disposed on each side of the housing. At least a second air inlet is disposed at the bottom of the housing and connected to the air-flow channel.

The number of the air-flow channels is one or more. If more than one air-flow channel is used, at least a spoiler is disposed between adjacent air-flow channels whereby separating the air-flow channels. Each of the air-flow channels may be completely independent (namely separated from each other without connection) or semi-independent (namely separated from each other but connected). Surface of the air-flow channel is a smooth parabola in the shape of a stream line, which increases a length of a path of air passing therethrough and an air speed. At least a wind indicator driven by air is disposed in the air-flow channel and supplies power to a fuel cell.

The existing vehicle consumes enormous energy during traveling since its front portion and side portion knocks into the air resistance wall and has a pressure region at the back thereof. As for the vehicle of the invention, since air of the air resistance wall and the air resistance hole is induced into the air-flow channel, a pressure region is formed in the front of the vehicle and in the vicinity of the air inlet on each side thereof, and the air is sprayed from the back of the vehicle at a speed higher than the vehicle speed, the air instantly eliminates resistance of the pressure region, and eliminates the pressure region at the back of the vehicle and a big pressure region generated by the air resistance hole, and forms a high pressure region, which saves power and increases the vehicle speed.

The outer portion surrounds the inner portion, and the air-flow channel is disposed therebetween and operates to allow air to pass through. The inner portion is a seal, and air cannot enter therein. The outer portion is a ventilation layer that allows air in the vicinity of the vehicle to enter the air-flow channel and to be sprayed form the air outlet. The air inlet is disposed in the forefront of the housing knocking to the air resistance wall and has an area approximately or completely the same as the housing, the air outlet is disposed at the back of the vehicle and connected to the air-flow channel.

A concave hole is disposed below the inner portion of the housing, and connected to the air inlet and the air outlet. The concave hole is in the shape of a stream line. The inner portion and the outer portion are in the shape of a stream line, which makes it possible for air to quickly pass through the air-flow channel without hindrance and to be sprayed from the air outlet. A removable sleeve is disposed on the air outlet and operates to adjust a direction, and makes it possible for air to be sprayed from three directions. By adjusting an angle by the removable sleeve at different vehicle speeds, the air sprayed from the air outlet is capable of preventing closing of the air resistance hole entrance.

An airflow controller is disposed in the decorative window and operates to adjust an angle, or air inlets in the shape of uniformly-distributed bars, diamonds, square grids, cells, circular holes, stream lines and so on are disposed in the decorative window. At least an air inlet is disposed at the bottom of the housing, and operates to induce air at the bottom of the vehicle in the air-flow channel, whereby balancing air speed at the bottom of the vehicle with that in the air-flow channel before the air is discharged from the air outlet. Thus, problems such as unsafe traveling and waste of gas caused by lift resistance (since air speed at the bottom of the vehicle is less than that at the top thereof) are solved. As long as the air speed at the bottom of the vehicle is great than or equal to that at the top thereof, the vehicle is capable of traveling more quickly, safely, stably and economically.

A rotating head is disposed between the concave hole and the air inlet, and a contact surface between the rotating head and the air has multiple concave or convex helixes for dividing the air. The rotating head is in the shape of a cone, a flying plate, a hemisphere, an impeller, a stream line and so on, and can be driven by a motor. As the vehicle traveling at a high velocity knocks into the air resistance wall, under centrifugal force, air in front of the vehicle is separated via the rotating head and an air-flow channel is instantly formed, which prevents resistance generated by the air knocking into the housing and makes it possible to induce air into the air-flow channel.

As for the vehicle of the invention, an accelerator pedal can be removed and only a brake pedal is used. The stepless control button disposed on a steering wheel adjusts a rotation speed of the motor, which makes the vehicle more convenient for use and safely since many traffic accidents are caused by erroneous operation of accelerator pedal and the brake pedal.

The number of the air-flow channels can be one or more. If more than one air-flow channel is used, both ends of each air-flow channel are connected to the air inlet and the air outlet. The air inlet can disposed in the front of the vehicle, or on one side of the vehicle, or at the bottom of the vehicle. The first sub-air-flow channel is connected to the second sub-air-flow channel, and to the air inlet. The air outlet is connected to the second sub-air-flow channel. A cross section of one of the first sub-air-flow channel and the second sub-air-flow channel is curved and in the shape of an ellipse, a circle, a rectangle, a snake, a loop or a stream line. Thus a main body of the vehicle is formed by the curved outer portion and the curved inner portion. After the windshield, the door, the separating plate and the engine are added, a beautiful vehicle is formed. Each of the air-flow channels can be in the shape of a stream line. A spoiler is disposed at the bottom of the vehicle and operates to increase an air speed.

In reforming an existing vehicle, the spoiler can be added to the bottom thereof, or an air-flow channel disposed on a spoiler of the air inlet is connected to the air inlet and the air outlet, so as to reduce energy consumption of the vehicle. The spoiler having a length no less than the upper portion of the vehicle increases and balances an air speed in the air-flow channel and that at the bottom of the vehicle (namely between the spoiler and the ground), and causes an air speed of the inner portion at the back of the vehicle to be approximately equal to that of the outer portion, which completely eliminates the lift resistance. Most or all the lift resistance can be eliminated if the spoiler is disposed at the bottom of the vehicle. To eliminate lift force of the vehicle, the spoiler is disposed at the bottom of the vehicle, or the air inlet at the bottom of the vehicle is connected to the air-flow channel, or both the spoiler and the air inlet are used.

Since the lift resistance is eliminated, the weight of the vehicle is only ⅕ than that of a normal car, energy is saved by approximately 80%, and production cost is significantly reduced.

The invention reduces a distance between the bottom of the vehicle and the road, increases an air speed with the help of the spoiler disposed at the bottom thereof, decreases the air resistance, and eliminates the lift resistance.

A length of the air-flow channel at the bottom of the vehicle is greater than that of an upper portion of the housing, which causes an air speed at the top of the vehicle to be higher than that at the bottom thereof, and eliminates the lift resistance. Air movement during traveling of the vehicle is completely changed, and air pressure at the top of the vehicle stably presses the upper portion of the housing of the vehicle, which makes the vehicle travel more faster, stably, safely and economically, and thus the lift resistance disappears. At this time there is no need to eliminate the lift resistance by increasing weight of the vehicle, and the vehicle only needs to have some basic functions, which greatly reduces energy consumption and production cost of the vehicle.

The first air inlet having an area approximately or completely the same as a front portion of the housing induces air of the air resistance wall in the air-flow channel, and the air inlets uniformly distributed around the housing induce air of the air resistance hole in the air-flow channel and reduce resistance of the air resistance wall and the air resistance hole.

Preventing the air resistance hole from being closed is a key point of solving a problem of high energy consumption. Air of the air resistance wall is induced from the front of the vehicle, and air of the air resistance hole is sprayed from the air outlet. At this time, air of the air resistance hole surrounds the air resistance hole entrance, reverse resistance is turned into forward driving force, the air instantly fills the pressure region at the back of the vehicle, which causes a big and a low pressure region to disappear, and a high pressure region to be formed at the back of the vehicle. A pressure region is formed at the front portion of and in the vicinity of the vehicle, and a high pressure region is formed at the back thereof, which makes the vehicle more economically and reduces energy consumption.

Traditional energy-saving vehicles such as compressed-air-driven vehicles, solar vehicles and fuel cell vehicles are difficult to be commercialized because 1) they are too heavy; 2) transmission systems thereof are too complex, and a great part of power is used by the transmission systems that overcome the lift resistance and air resistance by increasing weight thereof. The vehicle of the invention features a light weight, simplifies the transmission system to the great extent, and provides a new way for commercializing the energy-saving vehicle.

To summarize, the invention is very simple, practical and reliable, and provides a novel method for producing and reforming traditional compressed-air-driven vehicles, solar vehicles and fuel cell vehicles that features short use time and a difficult recharging process.
