Description

  The present invention is a power generation device mainly used for charging a mobile phone, and can generate power constantly due to vibrations that occur during normal mobile walking, etc. A power generation device that can be charged is provided.

  Recently, the penetration rate of mobile phones has been extremely high, and since the frequency of use is high, the charging method when going out has become an issue. There is a hand-held type for emergency use, but it is not suitable for carrying, and the labor required for power generation is large. On the other hand, some use the power generated by sunlight, but it is not sufficient in terms of performance. Patents have been filed for patents that use the vibration during walking and those that use changes in the relative positions of the magnet and coil, but it is difficult to realize because of its structural complexity.

The application patents in the above description are shown below.
JP 2009-225650 A

  The present invention has been established under the above-described background, and its problem is to provide a power generation device for charging a mobile phone having a structure capable of generating power by vibration in a normal walking state when going out. It is an object of the present invention to provide a power generation device that can easily perform emergency charging when a storage amount is insufficient due to a time call or the like.

  According to a first means of the present invention, a pulley is formed on a rotating shaft of a generator, a spring biased in a coil shape is wound around the pulley, and the other end of the spring is movable with respect to the generator. It is an object of the present invention to provide a power generator configured to generate electricity by changing the distance between the generator and the other end of the spring.

  The second means of the present invention is to provide a power generator configured to attach a generator to a mobile phone, attach a weight to the other end of the spring, and use the generated power for charging the mobile phone.

  According to a third means of the present invention, a pulley is formed on the rotating shaft of the generator, a spring energized in a coil shape is wound around the pulley, the other end of the spring is attached to the mobile phone, and the generated power is transferred to the mobile phone. A power generator configured to be used for charging is provided.

  The fourth means of the present invention provides a power generation apparatus in which the generator and the other end of the spring are coupled by a coil spring and an extension limiting rope.

  The power generator according to the present invention is obtained by the reciprocating rotation of the generator rotating shaft by the other end of the spring wound around the pulley formed on the rotating shaft of the generator moving by vibration during normal walking. The battery can be charged with the generated power, and if the amount of electricity stored is insufficient, the distance between the generator and the other end of the spring can be forced by shaking the mobile phone held by hand. It is possible to charge rapidly by changing continuously and obtaining large power from the generator. This operation can greatly reduce the labor compared with the hand-operated generators currently on the market, and its efficiency is also high. Note that the charging device is very compact, lightweight, and inexpensive because only a small generator and a coiled spring are the main components and complicated parts such as a speed increasing gear and a handle are unnecessary. Therefore, it can be carried as an accessory of a mobile phone at all times, and since it is not necessary to be charged by a household power source in a normal use state, there is also a power saving effect, and the effect is great.

  As is apparent from the above description, the power generation device of the present invention can always easily charge a storage battery of a mobile phone, and is compact, lightweight, inexpensive and can be used efficiently.

The best mode of the power generator of the present invention is to form a pulley on the rotating shaft of the generator, wrap a coil-energized spring around the pulley, and allow the other end of the spring to move with respect to the generator. It is an object of the present invention to provide a power generator configured to generate power by changing the distance between the generator and the other end of the spring.

Another form of the power generator of the present invention is to provide a power generator configured to attach a generator to a mobile phone, attach a weight to the other end of the spring, and use the generated power for charging the mobile phone. . It is desirable that the generator and the other end of the spring are connected by a coil spring and an extension limiting rope.

Embodiments of the present invention will be described below with reference to the drawings.
1 and 2 are side sectional views showing the structure of an embodiment of the present invention.
1 and 2, the generator 1 has a pulley 3 formed on its rotating shaft 2, and a plate-like spring 4 biased in a coil shape is wound around the pulley 3. One end portion of the spring 4 is wound around the pulley 3 as described above, and a weight 5 is fixed to the other end, and is connected to the generator 1 by a coil spring 6 and a limiting rope 7. The generator 1 is electrically coupled to the storage battery 11 via a rectifier 8 via a charging circuit 10 built in the mobile phone 9, and is attachable / detachable as required by an attaching / detaching mechanism 12. The structure of the attachment / detachment mechanism 12 is not particularly limited, but a system that does not separate by a simple tensile force is desirable. The coil spring 6 prevents the weight 5 from being attracted to the mobile phone 9 by the urging force of the spring 4, and the distance between the weight 5 and the generator 1 changes with a small force, so that the rotating shaft always keeps rotating easily. Is for the purpose. The restricting cord 7 is for preventing the coil spring 6 from being stretched and applying a tensile load to the spring 4 when an excessive force is applied to the weight 5.
FIG. 1 shows a state where the distance between the generator 1 and the weight 5 is short, and FIG. 2 shows a state where the distance between the generator 1 and the weight 5 is long.

FIG. 3 is a side sectional view showing the structure of another embodiment of the present invention.
In FIG. 3, the generator 1 has a pulley 3 formed on its rotating shaft 2, and a plate-like spring 4 urged in a coil shape is wound around the pulley 3. The other end of the spring 4 is coupled to the mobile phone 9 via the attachment / detachment mechanism 12. A cable 13 electrically connects the generator 1 and the rechargeable battery 11 via the rectifier 8 and the charging circuit 10. In the case of the embodiment shown in FIG. 4, since the generator 1 also serves as the weight 5, the overall weight can be reduced.

The operation of the power generating device having the above structure will be described.
In FIG. 1 and FIG. 2, when the mobile phone 9 is held in a hand or when walking in a holder case, the generator 1 and the weight 5 vibrate individually so that the mutual distance always changes. .
Therefore, as shown in FIG. 2, when the spring wound around the pulley is stretched, the portion wound around the pulley 3 is unwound, so that the rotating shaft 2 rotates in the direction of arrow B , and when shortened , as shown in FIG. By wrapping around the pulley 3, it rotates in the direction of arrow A. The generated power generated by the reciprocating rotation is rectified by the rectifier 8 and supplied to the storage battery 11 via the charging circuit 10. It is desirable to set the windings of the generator 1 so as to generate a necessary charging voltage at a relatively low rotational speed. When the amount of power storage is insufficient due to a long-time call or the like, the change in the positional relationship between the generator 1 and the weight 5 is increased by forcibly shaking the mobile phone 9 by hand, and the power generation amount increases. If the circuit for changing the voltage to current is included in the charging circuit 10, the storage battery 11 can be effectively charged.

  In FIG. 3, the generator 1 is suspended by a coil spring 6, and the other end of the spring 4 is coupled to a mobile phone 9 via an attachment / detachment device 12. In this state, when the mobile phone 9 is held in the hand as in the above case or when walking in a holder case, the generator 1 vibrates separately from the mobile phone 9, so the rotating shaft 2 is a spring. 4 reciprocates in response to the expansion and contraction of 4. Although the operation is the same as the state shown in FIGS. 1 and 2, since the weight 5 is not used, the overall weight can be reduced. It is desirable to use the cable 13 having excellent flexibility.

  As apparent from the above description, the power generator of the present invention can easily charge a storage battery of a mobile phone with a simple structure at all times, and is compact, lightweight, inexpensive and can be used efficiently. Further, charging can be performed rapidly by forcibly shaking the mobile phone 9, and the effect is extremely remarkable.
