       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to an on-road energy conversion and vibration absorber apparatus in which the kinetic energy received from moving vehicles (including motorcycles and bicycles) and pedestrians are converted into a potential energy using a restorable elastic element to compress and pressurize a fluid, and then to drive a vane wheel by releasing the pressure of the pressurized fluid. The vane wheel in turn drives a generator to generate electric energy. 
         [0004]    2. Description of the Prior Art 
         [0005]    Continuous rising of the oil cost has been affecting the economy in the whole world that the problems of environmental protection, energy saving, carbon reduction and anti-global green house effect have drawn more attention of the people than ever. At the same time, the development of new and non-contamination energy source is a paramount importance in the present day. 
         [0006]    As it is well-known, the traditional steam power plant produces a large amount of carbon dioxide which aggravates the green house effect, the hydraulic power plant is destructive to natural environment in construction and power supply is not reliable during low water periods, and the nuclear power plant is said to be the most threatful to the security. The wind power and solar light are considered to be the new hope of two clean energy sources. However, the both are sometimes geographically restrictive by reason of local climate. 
         [0007]    The inventor of the present invention who has a great interest in development of new energy sources has paid attention to the fact that there are so much energy wasted by the vehicles using inefficient engines which produce a large amount of exhaust gases containing harmful ingredients and heat dissipated along the roads to cause environmental pollution. How nice should it be possible to restore such wasted energies for reuse! 
         [0008]    In a bid to tackle this problem, the present inventor has dedicated great efforts for years to studying and improving these defects and has come up with the on-road energy conversion and vibration absorber apparatus as provided in this invention that can be used to restore part of the vehicle even pedestrian&#39;s lost of energies on the road for reuse. 
       SUMMARY OF THE INVENTION 
       [0009]    It is an object of the present invention to provide an on-load energy conversion and vibration absorber apparatus in which the kinetic energy received from moving vehicles (including motorcycles and bicycles) and pedestrians are able to be converted into a potential energy using a restorable elastic element to compress and pressurize a fluid, and then to drive a vane wheel by releasing the pressure of the pressurized fluid. The vane wheel in turn drives a generator to generate electric energy. 
         [0010]    It is another object of the present invention to provide an on-load energy conversion and vibration absorber apparatus that in addition to performing the energy conversion, the vibration of vehicles can also be absorbed and alleviated. 
         [0011]    To achieve the above objects, the aforesaid apparatus comprises a restorable elastic compression unit to be laid on the road surface with a pressure receiver plate attached to the top thereof, and a pressure chamber is formed inside. The pressure receiver plate is for receiving the weights of those moving vehicles including motorcycles and bicycles and pedestrians weighing down thereon so as to compress and pressurize a fluid, mainly air, contained in the pressure chamber. An elastic compression unit is provided to support the pressure receiver plate and restore it to its initial position after the exerting weight is released. A fluid conduit with a check valve is installed abut on, and in connection with the pressure chamber, the check valve conducts the pressurized fluid to flow along the conduit in one direction and drives a vane wheel with a jet flow of the pressurized fluid by releasing it potential energy. The vane wheel in turn drives a generator to generate electric energy. And the vibration of the vehicles is alleviated by the cushion effect of the restorable elastic element. 
         [0012]    Meanwhile, the pressure receiver plate has a structure of a large square plate whose surface contains a number of small square grid shaped meshes, or patterned in a beehive configuration.

Therefore, during the operation, for some embodiments, the gas region  2110  may contain fluid. Under such circumstance, such the fluid in the gas region  2110  can reduce the backside pressure imposed on the head body  2003 . Meanwhile, the gas absorbed in the fluid can be led to the gas valve  2010  to leave the tank  2002 .

         [0069]    It should be noted that, for some embodiments, as shown in  FIG. 16 , the pressure in the gas region  2110  is kept constant through injecting gas into the tank  2002  via the gas valve  2010 . Then, the fluid that flows into the fluid region  2111  will impose more pressure on the gas in the gas region  2110  so as to store more internal energy inside the gas. 
         [0070]    The operation of an energy storage used in the present invention is described as follows. Please refer to both  FIG. 15 . The piston member  1511  moves up and down through the first ball region  2006  and second ball region  2611 . The gas region tube  2122  is used for adjusting the fluid tank  2002  pressure through the gas valve  2010 . For some embodiments, the gas valve  2010 , as shown in  FIG. 15 , is used for letting the gas absorbed in the fluid emit from the fluid and leave the fluid tank  2002 , but not used for injecting gas into the fluid tank  2002  to result in a higher pressure. If a higher pressure is required, gas can be input into the fluid tank  2002  through the gas valve  2010 . If the fluid tank pressure is too high, the gas inside the tank  2002  can be released through the gas valve  2010 . 
         [0071]    Please refer to  FIG. 15 . When the fluid coming from the first pipeline enters the fluid tank  2002  through the fluid input  2008 , the fluid inside the fluid region  2111  will push the piston member  1511  up. As a result, a form of potential energy is stored in the piston member  1511 . Next, when the fluid inside the fluid region  2111  leaves through the fluid output  2009 , the potential energy stored can be poured into the fluid again through the work done by the piston member  1511  on the fluid. 
         [0072]    For some embodiments, where a spring member  2007  is used, the spring member  2007  is stick to the head member  2003 , as shown in  FIG. 15 . When the fluid enters the fluid tank  2002  through the fluid input  2008 , a form of elastic energy will be stored in the spring member  2007 , because the spring member  2007  is expended. When the fluid leaves the tank  2002  through the fluid output  2009 , the elastic energy can be poured into the fluid again because the spring member  2007  will return to its normal length. 
         [0073]    For some embodiments, as shown in  FIG. 16 , the present invention uses an energy storage without the piston member. The operation of such the energy storage is described as follows. First, a predetermined amount of gas is input into the fluid tank  2002  through the gas region tube  2122 . Then, the gas region  2110  of the tank  2002  has a stable pressure and volume. Second, the fluid coming from the first pipeline enters the tank  2002  through the fluid input  2008 . Then, the volume of the fluid region  2111  will increase. As a result, the volume of the gas region  2110  will decrease, so that the gas pressure of the gas region  2110  will increase. That is, a form of potential energy will be stored in the gas region  2110 . Third, when the fluid inside the fluid region  2111  leaves the tank  2002  through the fluid output  2009 . The stored, potential energy will be poured into the fluid because the gas will do work on the fluid. 
         [0074]    For the operation of all kinds of energy storage used in the embodiments of the present invention, when the fluid is leaving the tank  2002  through the fluid output  2009 , the leaving fluid will have more stable energy so as to force an fluid machinery  731 ,  732 ,  733  to generate energy. For some embodiments, the energy provided by the car movement will be accumulated in the energy storage, and when the accumulation reaches a certain amount, the overall amount energy is then provided for driving fluid machineries. 
         [0075]    Please refer to  FIGS. 10 and 11 . The present invention provides alternative practices of an energy generating system. The energy generating system  10 ,  11  comprises a different energy transformer that has a fluid machinery  931 ,  932 ,  933 , an electrical power generator  761 ,  762 ,  763 , and a mechanism  941 ,  942 ,  943 . The fluid machinery  931 ,  932 ,  933  transfers energy to the electrical power generator  761 ,  762 ,  763  through the mechanism  941 ,  942 ,  943 . Please refer to  FIG. 10 . The fluid machinery  931  comprises a fluid inlet  9311  and a fluid outlet  9312 . It should be mentioned that in  FIGS. 10 ,  11 , the fluid machineries  931 ,  932 ,  933  also have a fluid inlet and a fluid outlet. 
         [0076]    The energy transformers used in  FIGS. 7-9  have a fluid machinery which is a fluid cylinder. The energy transformers used in  FIGS. 10 and 11  have a fluid machinery which is a fluid motor. 
         [0077]    For some embodiments, the applied fluid machinery is a fluid cylinder. For some embodiments, the applied fluid machinery is a fluid motor. 
         [0078]    The present invention also provides a variety of choices regarding mechanism used in the energy transformers of the present invention. 
         [0079]    As shown in  FIG. 17(   a ), for some embodiments, the mechanism is a belt drive. As shown in  FIG. 17(   b ), for some embodiments, the mechanism is a chain drive. As shown in  FIG. 17(   c ), for some embodiments, the mechanism is a gear drive. As shown in  FIG. 17(   d ), for some embodiments, the mechanism is a crank mechanism. As shown in  FIG. 17(   e ), for some embodiments, the mechanism is a rack and pinion. 
         [0080]    The operation of an energy generating system of the present invention is described as follows. 
         [0081]    Please refer to  FIGS. 7 ,  9 ,  10  and  11 . A vehicle  800  enters an area where there are several object holders  771 ,  772 ,  773 ,  774 . Please refer to  FIG. 12 , the vehicle  800  is moving in one direction  8001 . The weight of the vehicle  800  then is a force applied onto several pressure-transferring devices  1007 ,  1001 . It should be noted that, for some embodiments, the car  800  moving direction is perpendicular to the movement of the pressure-transferring devices. 
         [0082]    Please refer to  FIG. 13 , when the pressure-transferring device  1007  receives the weight force provided by the vehicle  800 , the force will be transferred from the contact member  1311  to the pushing member  1313 ,  1049 . Consequently, the pushing member  1049  will press the fluid tube  1019 . Then, the fluid inside the fluid tube  1019  will leave the tube  1019  through the outlet non-return valve  1003 . 
         [0083]    Please refer to  FIG. 13  again. When the weight force is removed from the pressure-transferring device  1007  (e.g., the vehicle  800  has passed the object holder), there is no force applied onto the contact member  1311 . Then, the pushing member  1049  will return to its original state. Because the part  1049  of the pushing member covering the fluid tube  1019  is made of elastic materials, the part  1049  will return to its original shape. So, the pushing member will move up. The contact member  1311  then will return to its original level. Meanwhile, the fluid in the energy generating system will enter the fluid tube  1019  through the inlet non-return valve  1002 . 
         [0084]    It should be noted that, for some embodiments, after the contact member  1311  is pressed, the fluid stored in the fluid storage  721  can be used for moving the contact member  1311  back to its original level. For some embodiments, a spring member can be used for doing so. Such the spring member can be inserted into the pressure-transferring device to perform such function. 
         [0085]    For some embodiments, after the contact member  1311  is pressed, the fluid stored in the fluid storage  721  is then pressurized to be used for moving the contact member  1311  back to its original level. For some embodiments, a spring member could be incorporated with the pushing member  1313  to perform the function of moving the contact member  1311  back to its original level. 
         [0086]    Alternatively, when a pressure-transferring device  1001  shown in  FIG. 14  is applied, the weight force provided by the vehicle  800  will be directly applied onto the pushing member  1049  that covers the fluid tube  1019 . After the vehicle  800  passes the object holder, because of the elastic characteristics of the pushing member  1049 , the pushing member  1049  will return to its original shape. By doing so, the fluid will leave the fluid tube  1019  through the outlet non-return valve  1003  and then enter the fluid tube  1019  through the inlet non-return valve  1002 . 
         [0087]    It should be noted that, for some embodiments, after the pushing member  1049  is pressed, the fluid stored in the fluid storage  721  can be used for moving the pushing member  1049  back to its original level. For some embodiments, a spring member can be used for doing so. 
         [0088]    For some embodiments, after the pushing member  1049  is pressed, the fluid stored in the fluid storage  721  can be pressurized to be used for moving the pushing member  1049  back to its original level. For some embodiments, the elastic material  1049  of the pushing member  1049  could be functioning to move the pushing member  1049  back to its original level. 
         [0089]    After the fluid leaves the object holders, as shown in  FIGS. 7 and 10 , the fluid will enter the energy storage  633 . The energy storage  633  may provide additional energy to the fluid. Then, when the fluid leaves the energy storage  633 , it may have more stable power to run the fluid machinery. 
         [0090]    It should be noted that, for some embodiments, the energy storage  633  is used for accumulating the energy input from the pressure-transferring devices and, then, providing the stable energy to the fluid machineries. 
         [0091]    Alternatively, as shown in  FIGS. 9 and 11 , when the energy storage is not used, the fluid will directly enter the fluid machinery to run it. 
         [0092]    Please refer to  FIGS. 7 ,  9 ,  10  and  11  again. The fluid enters the fluid machinery  731 ,  732 ,  733 ,  931 ,  932 ,  933  to use hydraulic force to produce mechanical power. Then, the fluid will leave the fluid machinery. 
         [0093]    Next, the fluid will enter the fluid storage  721 . Then, the fluid will leave the fluid storage  721  to begin a new cycle of the operation. For some embodiments, during the operation, the pressure in the fluid storage  721  will first maintain constant, and then force the reflux to flow to the object holders  771 ,  772 ,  773 ,  774 . 
         [0094]    The present invention also provides more details about the operation of the energy transformer  78 . When the fluid machinery is driven to create mechanical power, the mechanical power will run the mechanism  741 ,  742 ,  742 ,  941 ,  942 ,  943  as shown in  FIGS. 7 ,  9 ,  10  and  11 . Then, the mechanism will begin to drive the electrical power generator to generate electricity. 
         [0095]    It should be noted that, for some embodiments, the device  78  comprises a fluid actuator and a power transmission. The fluid actuator may be a hydraulic cylinder or hydraulic motor. The power transmissions are shown in  FIG. 17 . 
         [0096]    The electricity from the electrical power generators  761 ,  762 ,  763  will be transferred in the power lines that are set in parallel. The electricity is transferred to the power converter  1974 . As a result, the energy generating system can begin to provide electricity. 
         [0097]    It should be noted that, for some embodiments, the power converter  1974  can provide the electricity generated to the general public in terms of parallel circuits. Alternatively, the generated electricity may be stored in a battery. 
         [0098]    It is apparent to a person skilled in the art that the basic idea of the invention can be implemented in many different ways. The invention and its embodiments are thus not restricted to the examples described above, but may vary with the scope of the appended claims.
