Description

  The present invention relates to a human-power accumulator that uses a commercially available bicycle as a drive source.

A conventional example will be described with reference to FIGS. Conventionally, as shown in Japanese Patent Application Laid-Open No. 2003-206854, the bicycle pedal 22, the saddle 28, the handle 27, and the power generation device 21 are integrated (FIG. 5). The power generation of this power generator is performed as follows. FIG. 6 shows the structure of the power generation device 21. A human stepping on the pedal 22 with his / her foot force turns the rotating shaft 23 of the pedal 22 as if riding a bicycle. The rotating shaft 23 is connected to the generator 26 via the main gear 24 and the sub gear 25. As described in Japanese Utility Model Publication No. 3089392, the force of the person stepping on the pedal 22 is transmitted to the generator 26 to generate power. Done.
JP 2003-206854 A Actual No. 3089392

  However, as shown in the conventional example, the pedal, saddle, handle, and generator cannot be separated unless they are disassembled, and the size is the same as a normal bicycle type training machine. It was heavy only by incorporating functions and was inconvenient for storage and transportation.

In addition, since the conventional example shows a configuration in which a saddle, a handle, a pedal, and a generator are integrated, the gear ratio from the pedal to the generator is fixed, and the rotation speed of the rotating shaft of the pedal is fixed. The number of rotations of the generator with respect to can not be easily changed, it is difficult to adjust the load widely for humans with different physical strength, and for those who do not have physical strength, the load on the pedal is large and it is not possible to generate power for a long time Met.
Further, the conventional human power generator has no idea of storing electric power and using it as an emergency power source in an emergency.

  The present invention has been made to solve such problems, and an object of the present invention is to provide a small and lightweight human power storage device in which a drive unit of a generator is separated. . Further, an object of the present invention is to provide a human power accumulator capable of changing the ratio of the rotational speed on the drive side and the rotational speed on the generator side.

  In order to solve the above-described problem, a human power storage device according to claim 1 includes a machine base, a support roller and a power generation roller that are rotatably arranged in parallel at a predetermined interval on the machine base, A roller-side pulley that is coaxially supported by the power generation roller, a generator disposed on the machine base, a power-generation pulley that is pivotally supported by the rotating shaft of the generator, the power-generation pulley, and the A power generator mounted on the roller pulley with a belt, a charge control device that converts power from the generator, a storage battery, power stored in the storage battery, and DC / DC that converts power from the generator And an AC converter.

  According to a second aspect of the present invention, in addition to the invention of the first aspect, the human power storage device includes a roller side pulley that is coaxially supported by the power generation roller or a power generation side pulley that is supported by the rotating shaft of the generator. The shaft is supported by pulleys having different diameters.

(A) Since the human-power-generating power storage device of the present invention is composed only of a portion that converts kinetic energy generated by the rotational force of the bicycle wheel into electrical energy, it is small and lightweight.
(B) Bicycles are easily available, so if a bicycle breaks down, you can prepare a substitute bicycle. Since the human-power-generating power storage device of the present invention does not have a functioning part of a bicycle, it is less likely to fail due to a small number of parts.
(C) Since the ratio of the rotation speed of the roller and the rotation speed of the generator can be changed, the load applied to the power generation can be made heavy or light, so that it can be adjusted according to the physical strength of the person who rides the bicycle.
(D) The generated electric power is stored in a storage battery and converted to an alternating current of 100 V by a DC / AC converter. If there is a bicycle and a person who rides it in an emergency such as a disaster, lighting and equipment can be driven by an AC power source, and electricity can be used without fuel. In other words, it has optimal properties as an emergency power source.

A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing a state where the apparatus and the bicycle are placed.
In the figure, reference numeral 1 denotes a human-power-generating power storage device, which includes a power generation device 2 and a power storage device 3. In the power generation device 2, a support roller 5 and a power generation roller 6 are rotatably supported in parallel on a machine base 4, and the surface of the power generation roller 6 is subjected to anti-slip processing. A roller-side pulley 7 having a diameter larger than the diameter of the power generation roller 6 is supported on the power generation roller 6 coaxially with the power generation roller 6. A generator 8 is disposed on the machine base 4, and a generator pulley 9 is pivotally supported on the rotating shaft of the generator 8, and a belt 10 is mounted on the roller pulley 7 and the generator pulley 9. .
The power storage device 3 includes a charge control device 11, a storage battery 12, and a DC / AC converter 13, and is connected to the generator 8 with a cable 14.

In this method of using the human power storage device 1, the rear wheel 16 of the bicycle 15 is placed on the support roller 5 and the power generation roller 6 of the power generation device 2.
The bicycle 15 may be any commercially available bicycle. When the bicycle 15 is squeezed, the rear wheel 16 of the bicycle 15 rotates, and the rotational force is transmitted to the power generator 2 to rotate the generator 8. The mechanism by which the rotational force of the rear wheel 16 of the bicycle 15 is transmitted to the generator 8 will be described in detail with reference to FIG. The rear wheel 16 of the bicycle 15 is placed on the support roller 5 and the power generation roller 6. When the rear wheel 16 of the bicycle 15 is rotated by human power, both the support roller 5 and the power generation roller 6 rotate. Since the surface of the power generation roller 6 is anti-slip processed, the rotational force of the rear wheel 16 of the bicycle 15 is transmitted to the power generation roller 6 without loss. A roller pulley 7 is coaxially attached to the power generation roller 6, and when the power generation roller 6 rotates, the roller side pulley 7 also rotates. The rotation of the roller side pulley 7 is transmitted to the power generation side pulley 9 via the belt 10. Since the power generation pulley 9 is attached to the shaft of the generator 8, the shaft of the generator 8 is rotated by the rotation of the power generation pulley 9, and the generator 8 generates power.

  How the generated electric power is used will be described with reference to FIG. The power generated by the generator 8 is first converted into a form suitable for charging by the charging control device 11 through the cable 14. The electric power is stored in the storage battery 12. The stored electric power and the electric power while the generator 8 is rotating are converted into AC 100 V AC by the DC / AC converter 13. AC100V can operate normal electrical equipment

You can use a commercially available bicycle that you use everyday. Therefore, the power generation device does not have a steering wheel, pedal, or saddle, which are components of the bicycle. Therefore, it is easier to store and move the device than before.
Electricity can be generated only by human leg power, and bicycles are generally easily available. Therefore, it is possible to supply electric power necessary for watching electric lights, televisions, etc. at the time of a disaster without fuel and complicated devices at home. Moreover, if a plurality of public facilities are installed and bicycles are alternately carried by visitors, it is possible to store electric power in case of a disaster.
Because it is small, it is more resistant to earthquakes than large equipment and is easy to transport.

In this embodiment, it has been described that the transmission of the rotational force of the bicycle is performed by pulleys and belts, but the same can be realized by using chains, gears, and the like. Also, by providing a pulley with the same diameter on the support roller and the power generation roller and mounting the belt, the rotational force of the support roller can be transmitted to the power generation roller, and the power generation roller rotates with a light force. Therefore, it is possible to generate power with a lighter power.
In addition, although the power generation device 1 is shown with the power generation device 2 and the power storage device 3 as separate units, the power storage device 3 may be integrally provided on the machine base 4 of the power generation device 2.

A second embodiment of the present invention will be described with reference to FIGS. Portions common to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
In FIG. 3, the human-power-generating power storage device 1 includes a power generation device 2 and a power storage device 3. In the power generation device 2, a support roller 5 and a power generation roller 6 are rotatably supported in parallel on a machine base 4, and the surface of the power generation roller 6 is subjected to anti-slip processing. As shown in FIG. 4, a pulley 17 having a different diameter, that is, a large pulley 18 and a small pulley 19 are supported on the power generation roller 6 coaxially with the power generation roller 6. A generator 8 is disposed on the machine base 4, and a generator pulley 9 is pivotally supported on the rotating shaft of the generator 8, and a belt 10 is fitted to the pulley 17 and the generator pulley 9.

In this embodiment, pulleys having different diameters as shown in FIG. 4, that is, a large pulley 18 and a small pulley 19, are coaxially attached to the power generation roller 6. A pulley around which the belt 10 of the pulley 17 is wound is, for example, a large pulley 18. Since the pulley small 19 is changed, the ratio of the rotational speed of the rear wheel 16 of the bicycle 15 and the rotational speed of the generator 8 can be changed. The power generation mechanism is the same as that of the first embodiment, but the force required to ride the bicycle can be changed by changing the ratio of the rotation speeds.
For this reason, since it becomes possible to ride a bicycle with an optimal load even for a person with different leg strength, it is possible to generate power for a long time and to store electricity.

In this embodiment, the method using two pulleys having different diameters has been described. However, if necessary, a larger number of pulleys can be attached.
Further, instead of a pulley, a gear and a chain may be used instead of a bicycle chain, or a gear whose gear ratio can be changed may be used.

It is explanatory drawing which shows the use condition of the 2nd Example of this invention. FIG. 6 is a perspective view of a pulley in which a plurality (two) of pulleys having different diameters are mounted on a concentric circle according to a second embodiment of the present invention. It is a reference figure which shows the whole apparatus of a prior art example. It is a reference figure which shows the power generation principle of a prior art example.
