Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mobile phone, and more particularly to a mobile phone having a power generator as a power source in addition to a rechargeable battery.

[0002]

[Prior art]

 Since mobile phones have the great advantage that they can talk while walking in a communicable area, their use has been spreading rapidly in recent years and has been steadily expanding. However, on the other hand, mobile phones only have a fixed capacity rechargeable battery as their power source, which limits the usage time. State. Such a state often occurs without the user's knowledge, and when the charging device connected to the commercial power supply cannot be used, the mobile phone cannot be used. In order to deal with such a situation, manual generators are commercially available, but it is inconvenient to carry both a mobile phone and a generator. For this reason, mobile phones incorporating a manual generator have been proposed.

For example, Japanese Patent Application Laid-Open No. 10-322428 discloses that a knurl partially projecting from a main body of a mobile phone is rotated by a finger, and the rotation is accelerated by a gear train. A mobile phone configured to transmit to a rotor is disclosed. The mobile phone described in Japanese Utility Model Laid-Open No. 6-23162 employs a configuration in which a self-excited DC generator is driven by the restoring force of a mainspring wound by a manual lever. Further, Japanese Patent Application Laid-Open No. 2000-23378 proposes that a built-in battery is charged by power generation by a firing method, and an interface connector connected to an external connector of a mobile phone is used as necessary.

[0004]

[Problems to be solved by the invention]

 However, the conventional techniques as described above have the following disadvantages. That is, in the method described in Japanese Patent Application Laid-Open No. 10-322428, the knurl is simply rotated while being pressed with the thumb, and the number of rotations and the rotation speed are not sufficient, and the knurl is necessary for the operation of the mobile phone. It is difficult to obtain sufficient power. In the portable telephone described in Japanese Utility Model Laid-Open No. 6-23162 and Japanese Patent Laid-Open No. 2000-23378, since the power of the lever is temporarily stored in the mainspring, a large-sized mainspring is used to obtain sufficient power. Must be carried out, and the important portability of a mobile phone is lost.

[0005]

[Means for Solving the Problems]

 The present invention provides a main body provided with an input button, a display unit, a transmission unit and a reception unit, a power generation device provided inside the main body, and a driving device for manually driving the power generation device from outside the main body. And a speed increasing gear mechanism having a pulling cable and a one-way clutch, and when the pulling cable is pulled out from the main body, the rotor of the power generating device is connected to the rotor through the speed increasing gear mechanism. This is a mobile phone equipped with a manual power generation device characterized in that the mobile phone is configured to rotate.

Further, the present invention provides a main body provided with an input button, a display unit, a transmission unit and a reception unit, a power generation device provided inside the main body, and a manual operation of the power generation device from outside the main body.

And a storage battery such as a lithium ion battery.

FIG. 2 shows a configuration of a built-in power generator and a drive mechanism for driving the power generator. In FIG. 2, a power generator indicated by reference numeral 10 includes a casing 11 fixed inside a main body 1, and a stator 12 having a coil or a magnet attached thereto, and a magnet or a coil attached therein. An ordinary power generation unit including the rotor 13 is provided, and power generated by rotation of the rotor 13 is supplied to the storage battery via an electric circuit (not shown). The drive mechanism for driving the power generator 10 includes a speed increasing gear mechanism for driving the rotor 13 of the power generator 10 to rotate.

Further, in this example in which a drive mechanism is provided outside the casing 11, a pulley 15 whose peripheral surface is wound by a towing line 14 is rotatably supported via a support shaft 16 integrated with the pulley 15. ing. The towing line 14 has an appropriate length, for example, about 50 cm, and is fixed at one end to a pulley 15 and wound around the pulley 15 in a certain direction. Is connected to the base 7. The pulley 15 is provided with a spiral spring (not shown) that urges the pulling cable 14 to rotate in a winding direction, and a one-way mechanism that prevents the rotation from being transmitted to the support shaft 16 when rotating in the winding direction. And a clutch (not shown). The base 7 of the antenna 6 supports the antenna 6 so that it can expand and contract at a predetermined position in a normal call state. At the same time, the base 7 itself is pulled in a direction away from the main body 1 so that the cable 14 It is configured such that the pulley 15 can be rotated via the pulley.

On the other hand, a gear 17 fixed to a support shaft 16 integral with the pulley 15, a small-diameter gear 18 meshing with the gear 17, and a large gear integrated with the gear 18 are provided inside the casing 11 of the power generator 10. A gear speed increasing mechanism including a gear 19 having a diameter and a gear 20 having a small diameter integrated with the rotor 13 is housed. It is desirable that the speed increasing ratio of the gear speed increasing mechanism is set so that one rotation of the pulley 15 is increased to about 10 to 20 times.

In the mobile phone thus configured, when the storage battery is discharged and a normal operating voltage cannot be obtained, the main body 1 is held with one hand and the base of the antenna 6 is held with the other hand. 7 is pulled away from the main body 1. As a result, the pulley 15 of the drive mechanism rotates through the pull cord 14 connected to the base 7, and the rotation is increased through the gears 17 to 20 of the speed increasing gear mechanism. And the power is generated by the power generation device 10. By repeating this operation several times, the storage battery is charged with the power of the power generation device 10 and the mobile phone is supplied with a normal operating voltage and becomes operable. In the above embodiment, the tip of the towing line 14 is connected to the base 7 of the antenna 6, but a hole provided at an appropriate place of the main body 1 is penetrated, and an appropriate knob or ring is provided at the end. The same operation can be performed with the above configuration.

It is a figure showing that it was led out from the hole provided in. A groove is formed on the circumference of the two guide wheels 31, and each guide wheel is urged so as to sandwich the strap 32 therebetween. As a result, the strap 32 comes into close contact with the pulley 15, and the strap 32 becomes hard to slip.

FIGS. 5 and 6 show that the manual power generation device is configured to be detachably attached to the mobile phone main body. The mobile phone body 1 is provided with a spherical concave portion 43 and an insertion port 41. The case 33 in which the manual power generation device is accommodated has a pulling index outlet 34 for pulling out the towing line 14, a stopper 35 at the tip of the towing line, a connector 42 for transmitting generated electricity, and a mobile phone main body. By providing the hook 36 made of an elastic member for stopping, the manual power generator can be attached or detached as required.

Next, another embodiment of the present invention will be described with reference to FIGS. 7 and 8. FIG. In the mobile phone according to the second embodiment, a lever 21 pivotally supported at one end is provided on a side surface of the main body 1. This lever 21 has, on its free end side, a rack 22 extending along a part of an arc centered on a pivot point, and this rack 22 meshes with a pinion 23 provided in the main body 1. I have. The tip of the lever 21 is normally urged away from the main body 1 by the action of a return spring (not shown), but is fixed at the position closest to the main body 1 in a normal use state. Thus, it is desirable that the fixing member be fixed by a suitable fixing means such as a hook. The pinion 23 meshing with the rack 22 is connected to a gear 30 fixed to a support shaft 16 supporting a rotor of the power generator 10 via gears 24 to 28 constituting a speed increasing gear mechanism and a one-way clutch 29. ing.

When a sufficient operating voltage cannot be obtained from the storage battery due to the discharge, the operation of holding the main body 1 and the lever 21 at the same time, pulling the lever 21 toward the main body 1 with a finger, and then releasing the same is repeated. As a result, the gear 23 meshing therewith rotates via the rack 22, and this rotation is directly connected to the gear 30 via the gears 24 to 28 of the speed increasing gear mechanism and the one-way clutch 29. And the power is generated by the power generation device 10. In the process of returning the lever 21, the one-way clutch 29 allows the gear train to rotate in the reverse direction, so that the rotor 13 does not rotate in the reverse direction. By repeating this operation several times, the storage battery is charged with the power of the power generation device 10, and the mobile phone is operable by receiving the supply of the normal operating voltage.
