Description

  The present invention is an electronic device holder mainly having a function of being able to charge a mobile phone while carrying it, and is capable of generating power constantly by vibrations generated particularly when walking with a mobile phone. It is a holder having safety that ensures electrical connection with the machine and prevents damage or deterioration of durability due to excessive load applied to the joint. It is another object of the present invention to provide an electronic device holder that can be easily urgently charged when a storage amount is insufficient.

  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. As shown in Patent Document 1, a patent application has been filed as one that uses vibration during walking, as shown in Patent Document 1, but it is difficult to realize because of its structural complexity. In addition, as shown in Patent Document 2, there is a proposal of a structure of winding a cable around a pulley. However, it is impossible to obtain a stretching durability of 10 million times with a cable, and the mainspring mechanism has a large space. This is not realized because it is necessary to reduce the size of the apparatus. Also, although these do not detail the method of attaching / detaching the electrical connection between the electronic device and the generator, there are many requests that an unnecessary generator should be easily removed when using a mobile phone, and the attachment / detachment is also difficult. Regarding the method, if a load such as the weight of a mobile phone is applied to this part, there is a risk of dropping off due to breakage or a decrease in durability, which is an obstacle to practical use.

The application patents in the above description are shown below.

When you do this, you can easily remove the unwanted generator, and this part will not be subjected to loads such as the weight of the mobile phone, and it will provide a holder that will not fall off due to breakage or decrease the durability. is there. In addition, it is possible to easily perform emergency charging when the amount of power storage is insufficient due to a long-time call or the like.

A suspension coupling portion that couples the other ends of the cords is provided, and the suspension coupling portion is movable with respect to the generator. A holder for storing an electronic device is provided in the vicinity of the suspension coupling portion, and an electrical connector for electrically connecting the generator and the electronic device via a flexible electric wire is provided to the holder. The present invention provides a holder for an electronic device characterized in that it is configured so as to generate electricity by changing the distance from the suspension coupling portion.

  The second means of the present invention includes a generator, a pulley fixed to the rotating shaft of the generator, a stretchable plate-like wrapping spring that is energized in close contact with the pulley, and the plate-like A coil spring including a winding spring is provided, one end of the coil spring is attached to the generator, and a suspension coupling portion is provided that combines the plate-like winding spring and the other end of the coil spring, The suspension coupling is movable with respect to the generator.

To do.

  The power generator of the present invention is such that the rotating shaft of the generator is always reciprocally rotated by the other end of a plate-like wrapping spring wound around a pulley formed on the rotating shaft of the generator by vibration during normal walking. The battery can be charged with the power obtained from the mobile phone, and if the amount of electricity stored is insufficient, the battery can be forcibly held while holding the electronic device holder that holds the mobile phone in hand. Charging can be performed rapidly by expanding and contracting the coiled spring and rotating the generator pulley back and forth to obtain large power from the generator. This operation can greatly reduce the labor compared with the hand-operated generators currently on the market, and its power generation 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 convenience effect is great.

  Another effect of the present invention is that the power generator of the type that winds the cable with a pulley breaks in a short time due to the lack of cable bending and stretching durability, and the practicality is poor, so that the pulley is tightly wound around the pulley. It is possible to obtain a sufficient durability for several years by completely solving the problem by using a stretchable plate-like wrapping spring that is energized as described above.

  Another effect of the present invention is that a safety housing and electrical connection can be achieved by providing an electrical connection device for electrically connecting the generator and the electronic device to the holder for storing the electronic device, and simultaneously storing and electrically connecting the electronic device. In addition, it is possible to obtain the convenience of use that the generator can be easily disconnected when the mobile phone is used again.

  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 efficient to use, and has high durability and reliability. .

  Another embodiment of the electronic device holder according to the present invention includes a generator, a pulley fixed to the rotating shaft of the generator, and a stretchable plate-like winding spring that is energized as if it is tightly wound around the pulley. A suspension coupling portion provided with a coil spring containing the plate-like winding spring, one end of the coil spring being attached to the generator, and the other ends of the plate-like winding spring and the coil spring being coupled to each other The suspension coupling portion is movable with respect to the generator. A holder for storing an electronic device is provided in the vicinity of the generator, an electrical connector for electrically connecting the generator and the electronic device is provided in the holder, and the holder and the suspension coupling portion are connected to the generator.

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 winding spring 4 that is urged in a spiral shape is wound around the pulley 3. A suspension coupling portion 5 is fixed to the other end of the plate-like winding spring 4, and is coupled to the generator 1 by a coil spring 6 and a limiting rope 7. The generator 1 is electrically coupled via a rectifier 8 via a charging circuit 10 built in the mobile phone 9 by a storage battery 11 and an electrical connector 12 in a detachable state as necessary. The electrical connector 12 is provided inside a holder 13 that accommodates the mobile phone 9, and is coupled to the generator 1 via a flexible electrical cable 15. The generator 1 is preferably a brushless type having the same structure as a multipolar stepping motor. By using the generator with such a structure and efficiently generating power with a small number of revolutions, the mechanical structure such as the speed-up gear can be omitted, so that the cost can be reduced and the size can be reduced. . Furthermore, since there is no frictional resistance of the rectifying brush, the power generation efficiency is high, and it is freed from worrying about the decrease in durability due to its wear. The electrical connector 12 provided in the holder 13 may be of a contact type by a spring as in the normal charging holder. The holding band 14 provided on the holder 13 prevents the mobile phone 9 from inadvertently falling off the holder 13, and the mobile phone 9 can be easily removed from the holder 13 by slightly shifting the position. .

FIG. 3 is a side sectional view showing the structure of another embodiment of the present invention.
In FIG. 3, the generator 1 is provided at the lower part of the holder 13 and is directly coupled to the electrical connector 12, and the electrical cable 15 is omitted. The generator 1 and the suspension coupling portion 5 are coupled to both ends of the plate-like wrap spring 4 and the coil spring 6, and the holder 13 and the suspension coupling portion 5 are coupled to each other through a restriction rope 7. Reference numeral 16 denotes a cylindrical auxiliary member for preventing the holder 13 from being largely inclined by supporting the coil spring 6 in a state where the restricting cord 7 is loosened.

The operation of the power generating device having the above structure will be described.
1 and 2, the mobile phone 9 stored in the holder 13 is safely carried while being prevented from falling off by the holding band 14. In this state, the cellular phone 9 and the generator 1 are electrically coupled by the electrical connector 12 in the holder 13. Further, the suspension coupling portion 5 is attached to a belt or the like, and the mutual distance varies in a state where the suspension coupling portion 5 is coupled by the coil spring 6 and the limiting rope 7 due to vibration caused by walking. The generator 1 reciprocally rotates the pulley 3 by the expansion and contraction movement of the plate-like winding spring 4 wound around the rotating shaft 2 in close contact with the pulley 3 due to the mutual distance variation. That is, when the plate-like winding spring 4 wound around the pulley 3 is stretched, the portion wound around the pulley 3 is unwound so that the rotating shaft 2 rotates in the direction of arrow A. 4 is wound around the pulley 3 to rotate in the direction of arrow B. Due to this reciprocating rotational movement, the generator 1 charges the storage battery 11 via the electrical connector 12 and the rectifier 8 via the charging circuit 10 built in the mobile phone 9.

  In this case, the plate-like wrapping spring 4 wound tightly on the pulley 3 does not rub in contact with and away from each other in its expansion / contraction movement, so it is not worn even in repetitive movements and has excellent durability. In addition, since it is in a state of being tightly wound with respect to the pulley 3, it has an advantage that it can be greatly reduced in size as compared with a spring formed with a gap between each other like a spiral spring. As for durability, assuming that there are 3000 steps a day, 10 million expansion / contraction movements are performed in order to maintain the durability for 10 years. If a general cable such as a fiber bundled around the pulley 3 is wound, it will be rubbed in contact with each other and broken by thousands or tens of thousands of expansion and contraction due to internal friction caused by expansion and contraction. Become. If the durability is improved with a special material, the cost will increase significantly and the product value will be lost. The most excellent method that can be put into practical use is the method that uses the plate-like winding spring 4 that tightly winds according to the present invention. Since the limiting rope 7 has a small degree of bending, sufficient durability can be obtained by using a material similar to that used for fishing such as Tegs, and the flexible electric cable 15 has a small degree of bending and no force is applied. Therefore, even a commercially available product will not break.

  Further, the electronic device holder of the present invention does not require any modification to the mobile phone 9 itself. If the electric connector 12 itself is strong enough to suspend the mobile phone 9 with sufficient strength, a new coupling method is required, and the widely used current mobile phone cannot be used. . Therefore, the system of the present invention in which the mobile phone 9 accommodated in the holder 13 is configured so as to be safely carried with the holding band 14 being prevented from falling off, and the electrical connector 12 is provided inside the holder 13, The telephone 9 can be easily separated from the generator 1 during use without any modification, and the electrical connection can be made reliably, and its convenience and reliability are extremely high. In the case of the present embodiment, since the depth dimension of the electronic device holder is small, it is suitable for use in a state where it is suspended from the shoulder or neck.

  In FIG. 3, the generator 1 is provided at the lower part of the holder 13 and is directly coupled to the electrical connector 12, and the electrical cable 15 is omitted. The generator 1 and the suspension coupling portion 5 are coupled to both ends of the plate-like wrap spring 4 and the coil spring 6, and the holder 13 and the suspension coupling portion 5 are coupled to each other through a restriction rope 7. Therefore, the entire length of the apparatus is shortened, and the apparatus is easy to use with less shaking when used while being suspended from the waist belt. Since the cylindrical auxiliary member 16 prevents the holder 13 from tilting greatly in a state where the restricting cord 7 is loosened, the effect can be further enhanced.

  As a method of power generation while being carried, the practicality of this method is about 3000 steps if the power generation efficiency is 50% or more when the vibration amplitude is 20 mm and the mass of the holder 13 including the mobile phone and the generator is 200 g. It has been demonstrated that walking can sufficiently cover normal standby power. In addition, when the battery runs out due to a long phone call or the like, it is possible to talk for about 1 minute by forcibly extending and contracting about 100 times. In this case, if the durability is somewhat sacrificed, it is possible to generate power more easily by increasing the stroke by extending the length of the restricting cord 7 as necessary, and extending the length of the restricting cord 7 as required. Is possible. Although it is considered that another method using a piezoelectric element has been proposed, it is necessary to verify whether it is practically possible because its power generation efficiency is 5% or less.

In the description of the above embodiment, the cellular phone has been described. However, it is needless to say that the present invention is not limited to this and can be applied to all ordinary portable electronic devices having a storage battery inside. . In particular, since the mass of a slightly larger one is increased, the charging power is increased in proportion to that, which is suitable for the device. Needless to say, a bag suspended by two belts may have a plurality of generators.
As is clear from the above description, the electronic device holder of the present invention has a simple structure and can easily charge the storage battery of the mobile phone at all times, requires no modification of the mobile phone itself, is compact and lightweight, It is cheap and efficient, and it is very easy to disconnect the generator and use a single mobile phone as usual. In addition, charging can be performed rapidly by forcibly expanding and contracting the plate-like winding spring 4, and the effect is extremely remarkable.
