In addition, the transportation device 100 further comprises a battery 140. Besides providing power to the lamps 114, the battery 140 can also provide power to the electronic equipments disposed on the vehicle body 110, such as radio, recorder or CD player, etc. Battery 140 can be a lead-acid battery.
The power system 120 has an engine 1210, a gas pipe 1220 and a gas tank 1230. The engine 1210 is used to drive and to move the vehicle body 110. The gas tank 1230 stores high pressure noninflammable gas. The gas pipe 1220 is connected to the engine 1210 and the gas tank 1230 delivers the high pressure noninflammable gas to the engine 1210, so that the engine 1210 can drive the vehicle body 110 without using fuel.
The gas pipe 1220 has a switch valve 1222 to control the delivery of the high pressure gas to the engine 1210. The switch valve 1222 can be a regular gas pipe valve, such as a magnetic valve or a gas valve. When the switch valve 1222 is turned on, the high pressure gas enters the engine 1210. Due to the high pressure of the high pressure gas, the engine 1210 drives and moves the vehicle body 110. When the switch valve 1222 is turned off, the gas pipe 1220 is blocked to prevent the high pressure gas from entering into the engine 1210 so that no high pressure gas is delivered to the engine 1210, and therefore the engine 1210 can not drive vehicle body 110, and thus vehicle body 110 stops moving.
The reason why the high pressure gas in the gas tank 1230 can be delivered to the engine 1210 is that the pressure in the gas tank 1230 is higher than the pressure in the gas pipe 1220 and the engine 1210. Thus the high pressure gas can be transported from the gas tank 1230 to the engine 1210 via the gas pipe 1220. Therefore in order to transport the high pressure gas from the gas tank 1230 to the engine 1210, the pressure in the gas tank 1230 should be maintained at a higher pressure relative to that in the engine 1210. As the high pressure gas in gas tank 1230 is depleted, the pressure of the high pressure gas in the gas tank 1230 is correspondingly reduced, and when the pressure in the gas tank 1230 is reduced a pressure equivalent to that in the gas pipe 1220, the transportation of the high pressure gas from the gas tank 1230 to the engine 1210 stops. At this time, high pressure gas needs to be filled into the gas tank 1230 from an external source.
The high pressure gas may be filled into the gas tank 1230 from an external source via a check valve 1232 on the gas tank 1230. To fill the high pressure gas from the external source, as shown in
The high pressure gas may also be filled into the gas tank 1230 from the external source using other methods. Referring to
It should be noted that other external sources such as car dealers or auto repair shops may also supply the high pressure gas, which can be used to fill the gas tank 1230.
In addition, the gas tank 1230 also comprises a pressure gage (not shown in the diagram) to measure the pressure of the high pressure gas inside the gas tank 1230 which may serve to indicate the content of the high pressure gas inside the gas tank 1230.
As for the engine 1210, there may be a plurality of embodiments capable of driving the vehicle body 110.
The cylinder block 310 is hollow inside, and is connected to the gas pipe 1220. An exhaust valve (air release valve) 312, which may be used to discharge the high pressure gas is disposed on the cylinder block 310. The drive shaft 330 comprises a flywheel 332 and a shaft 334 which are tightly fastened to each other. An end of the shaft 334 is connected to the center of flywheel 332, and the long axle of the shaft 334 is roughly vertical to the flywheel. The drive shaft 330 is mainly used to turn the wheels 112 to rotate and to drive the vehicle body 110.
The driving methods employing the drive shaft 330 to drive the vehicle body 110 may be various. The turning shaft 334 of the drive shaft 330 may be connected to the wheels 112, or the drive shaft 330 drives the vehicle body 110 in conjunction with a plurality of gears or belts. However, the method of employing the drive shaft 330 for driving the vehicle body 110 is not used to limit the scope of the present invention.
The piston 320 comprises a connecting rod 322 connected to the drive shaft 330, and the end of the connecting rod 322 is pivoted with the flywheel 332. The end of the connecting rod 332 can be used as an axle to rotate on the flywheel 332.
In order to clearly describe how the engine 1210 drives the vehicle body 110, the cylinder block 300's three schematic working diagrams
Referring to
In addition, the gas pipe 1220 as shown in
The switch valve 1222 shown in
Next, referring to
As the piston head 324 being pushed, it drives the connecting rod 322 connected with the piston head 324. While the connecting rod 322 pushes the flywheel 332 to rotate the turning shaft 334. Therefore the drive shaft 330 is turned to drive and move the vehicle body 110.
Next, referring to
The continuous discharging of the high pressure gas from the cylinder block 310 continuously turns the flywheel 332 to continuously rotate the drive shaft 330. Although the connecting rod 322 can push the flywheel 332, however the rotating flywheel 332 may cause the connecting rod 322 to move up due to moment of inertia. If the flywheel 332 can not move the connecting rod 322 up, the flywheel 332 then can not rotate continuously, and therefore the drive shaft 330 can not rotate continuously so that the vehicle body 110 stops moving. Since the high pressure gas in the cylinder block 310 may prevent the piston head 324 from moving up, therefore the flywheel 332 can not move the connecting rod 322 up, therefore the drive shaft 330 can not continue to rotate. To make the flywheel 332 to move the connecting rod 322 up, the exhaust valve 312 is required to discharge the high pressure gas so that the flywheel 332 can move the connecting rod 322 up, thus the drive shaft 330 can continue to rotate.
When the connecting rod 322 moves up, the piston head 324 moves up accordingly. When the piston head 324 moves up until it reaches the upper end of the cylinder block 310, the cylinder 300 will return to a state shown in
The throttle valve 1224 functions to regulate the flow of the high pressure gas. Since the piston 320 in the cylinder 300 is pushed by the high pressure gas, therefore the greater the force with which the high pressure gas pushes the piston 320 is, the faster the drive shaft 330 rotates, and therefore the faster the vehicle body 110 moves. To increase the force with which the high pressure gas pushes the piston 320, a large amount of the high pressure gas is required to be delivered to push the piston 320. Therefore the throttle valve 1224 can increase the flow of the high pressure gas, so that the force that the high pressure gas pushes the piston 320 is increased, so that the moving speed of the vehicle body 110 is increased. Therefore the throttle valve 1224 is equivalent to the accelerator controlling the speed of the transportation device 100 and 200.
The main components of the cylinder 522 and the cylinder 524 are similar to that of the cylinder 300 (as shown in
The switching valve 510 is connected to the gas pipe 1220. The function of the switching valve 510 is to selectively deliver the high pressure gas to either cylinder 522 or cylinder 524. Since the engine 500 has two cylinders 522 and 524, therefore the flywheels 5232C and 5232D of the drive shaft 5230 can be driven in turn. However, in order to make cylinder 522 or cylinder 524 respectively drives the drive shaft 5230 in turn, the high pressure gas must be restricted not to enter cylinder 522 or cylinder 524 at the same time. Therefore the switching valve 510 is required. In conjunction with the rotation of the drive shaft 5230, the switching valve 510 periodically and alternately delivers the high pressure gas to the cylinder 522 and the cylinder 524, so that the drive shaft 5230 can rotate continuously, thus the vehicle body is driven to move. In addition, the advantage of using the switching valve 510 is that the vehicle body 110 can be driven in a different way with the engine 1210 which has to keep turning the bypass switch valve 1222 between the on and off states constantly to drive the vehicle body 110.
It is known from the above description, the principle of the power system 120 of the present invention is to drive the cylinders 522, 524 or 300 using the pressure of the high pressure gas as the power source to drive the vehicle body 110. Besides compressed noninflammable gas such as high pressure air, high pressure helium or high pressure nitrogen, the high pressure gas may also comprise high pressure helium and nitrogen in liquefied gas (for example liquid nitrogen or liquid helium). That is to say, the gas tank 1230 can store liquid nitrogen or liquid helium. The high pressure gas generated when the liquid nitrogen or the liquid helium is transformed from the liquid phase to the vapor phase is used to increase the air pressure in the gas tank 1230, so as to make the cylinders 522, 524 or 300 operate.
To sum up, the transportation device of the present invention can replace the automobiles that use gasoline as the power source, thus the gasoline shortage problem when the oil in the world is exhausted can be resolved. In addition, the cost on the power source of the transportation device can also be reduced without being affected by the daily increased oil price.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
