BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply for a portable electronic device and a portable electronic device incorporating the power supply.

More specifically, the present invention relates to an inductive charging device for inducing electrical energy using natural or artificial vibration energy and supplying the induced energy to a secondary battery.

In addition, the present invention forms a single power supply module by forming the inductive charging device and the secondary battery as one unit, and connects the power supply module to electronic equipment to supply a stable power. It concerns the device.

[0004] The present invention relates to a portable electronic device operated by using such a power supply device.

In particular, the power supply device of the present invention is useful for supplying power to a portable communication terminal device (for example, a cellular phone, a PCS phone, etc.), but is not necessarily limited to this.

[0006]

2. Description of the Related Art Electronic devices are generally classified into the following two categories.

[0007] One is fixed to one place for use, and the other is not fixed to a certain place, and can be used freely while being carried and carried by the user.

For example, the former includes a home television set and an audio set. Examples of the latter include portable communication terminals such as cellular phones, portable computers such as notebooks, portable cassettes,
There are portable CD players and the like.

Recently, the use of such portable electronic devices has been increasing. A power source for operating these portable electronic devices is indispensable.

[0010] In the case of an electronic product that is fixed to one place and used, such as a home television, an electrical facility (outlet) connected to a power distribution system of a power station is provided at the place of use, and when necessary, The user receives power by connecting the plug of the electronic product to the outlet.

On the other hand, in the case of a portable electronic device, a battery is used as a main power source. Of course, when the user stays in a specific place, the above-mentioned fixed electric equipment can be used in a limited manner.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

(First Embodiment) FIGS. 1 to 7 are drawings attached to explain a power supply device according to a first embodiment of the present invention.

This embodiment is an embodiment in a case where a mechanical generator portion for generating an induced electromotive force using natural or artificial vibration energy is fixed to a portable communication terminal device.

In the following, a cellular phone (Cellular ph), which is the most widely used portable communication terminal device, will be described.
(one: mobile phone).

Prior to describing this embodiment, a general configuration of a cellular phone will be described.

FIG. 1 is a front view of a cellular phone, and FIG.
Is a rear view, and FIG. 2B is a side view.

As shown in FIG. 1, the cellular phone includes a device case 1 built in an RF circuit (Radio frequency circuit) and the like, an antenna 2, a speaker 3, a display unit 4, a character / number key unit 5, And a microphone 6.

As can be seen from FIGS. 2 (A) and 2 (B), the cellular phone is provided with a storage section for storing the secondary battery 8 on the back of the case 1, and is provided in the storage section. The secondary battery 8 is detachably connected.

A detachable section 7 for attaching and detaching the secondary battery 8 is formed in the storage section of the cellular phone.
A plurality of charging contacts 9 are formed at the lower end of.

FIG. 3 is a rear view of the cellular phone to which the power supply of the present invention is fixed.

An antenna 11 is arranged at the upper end of the cellular phone device case 10, and a secondary battery 13 is mounted via a detachable portion 15. Outer surface of this rechargeable battery 13 (the part that comes into contact with the user when the user holds the cellular phone)
Is formed with an induced electromotive force generating means 17.

Therefore, when the user moves while carrying the cellular phone, fine vertical vibrations occur,
Due to this minute vibration, the induced electromotive force generating means generates electric energy to charge the storage battery.

When the storage battery is completely discharged and the cellular phone cannot be used, the user may artificially shake the cellular phone in the direction of arrow B in FIG. 3 to generate kinetic energy. it can.

An electromagnetic mechanism for producing electric energy using natural or artificial kinetic kinetic energy and an electric mechanism for using the generated electric energy to charge a storage battery are shown in the accompanying drawings. 6
This will be described with reference to FIGS.

First, FIG. 6 is an enlarged configuration diagram of the induced electromotive force generating means 17 mounted on the outer surface of the secondary battery 13.

As can be seen from FIGS. 3 to 6, the induced electromotive force generating means 17 is housed in a housing space 21 formed on the outer surface of the battery pack in which the secondary battery 13 is built.

The storage space 21 is preferably a rectangular slot, but is not necessarily limited to this.

The storage space 21 is provided with the induced electromotive force generating means 1.
7 is protected from external shocks, and electromagnetic disturbance caused by electromagnetic induction phenomenon (Electromagnetic disturban)
ce) to protect the internal electronic components of the cellular phone.

Therefore, it is desirable that the storage space 21 is electromagnetically protectively coated.

The induced electromotive force generating means 17 housed in the housing space 21 comprises an electromagnetic induction device 24 and elastic members 23 connected to both ends of the electromagnetic induction device 24.

The electromagnetic induction device 24 is a portion that generates an induced electromotive force using natural vibration energy generated according to the movement of the user or artificial kinetic energy of the user. As shown in FIG. 7, the electromagnetic induction device 24 includes a permanent magnet 25 and a bobbin 27.

The permanent magnet 25 and the bobbin 27 are mechanically connected to the elastic member 23, respectively.

Therefore, when the user carrying the cellular phone provided with the electromagnetic induction device 24 of the present embodiment moves, fine vertical vibrations are generated, and the fine vibrations are transmitted to the elastic member 23. . As a result, the elastic member 23 sustains the minute vibration so that the permanent magnet 25 and the bobbin 27 relatively swing.

When the permanent magnet 25 having a constant magnetic flux approaches and moves farther from the bobbin 27 on which a fixed number of coils are wound, a change in the magnetic flux is generated, and a change in the magnetic flux is generated. An induced electromotive force (induced electromotive force according to Faraday's law) is generated at both ends.

Further, when the user carrying the cellular phone provided with the electromagnetic induction device 24 of this embodiment shakes the cellular phone in the direction of arrow B in FIG. 3 in an emergency, the same process as described above is performed. An induced electromotive force is generated at both ends of the coil.

Elements such as the magnetic force of the permanent magnet 25 and the number of turns of the coil are appropriately designed in consideration of the capacity of the secondary battery, the weight of the cellular phone, and the like.

It is preferable that the elastic member 23 is a coil spring having a large elastic coefficient enough to respond to minute vibration and sustain the vibration. Substitution with equivalent means to achieve the desired result is fully possible in the state of the art.

As can be seen from FIG. 7, the electromagnetic induction device 24
The induced electromotive force generated at both ends of the coil wound around the bobbin 27 passes through the charge adjusting circuit 30 and the storage battery 2 of the mobile phone.
Charge 9

The charge adjusting circuit 30 includes a voltage adjusting circuit for boosting a minute induced electromotive force generated from the electromagnetic induction device to a voltage level suitable for charging the secondary battery.

The charge adjusting circuit 30 includes a rectifier circuit for converting an AC voltage generated from the electromagnetic induction device into a DC voltage.

FIG. 8 shows a specific embodiment of the charge regulating circuit.

As shown, the charge regulating circuit 30 of the present invention comprises an AC-DC converter 32, a first DC-DC converter 33, a second DC-DC converter 35, and a first super capacitor ( (Super capacitor) 34 and a second super capacitor 37.

The first and second supercapacitors 3
4 and 37 and the storage battery 36 are connected in parallel to the second DC-DC converter 35. In addition, the AC
-DC converter 32 is an induced electromotive force generating means (generator) 31
And the second DC-DC converter 35 is connected to an external circuit. Hereinafter, a detailed configuration of each component of the charge adjustment circuit 30 will be described.

The AC-DC converter 32 converts an induced AC voltage of about 200 mV generated from the induced electromotive force generating means 31 into a DC voltage of about 1.8 V.

That is, the AC-DC converter 32 is roughly composed of a booster for boosting a voltage and a rectifier for rectifying an alternating current. The reason for boosting the voltage is to increase the voltage generated from the bobbin of the induced electromotive force generating means to a constant value because it is very low.
Therefore, when the voltage generated from the bobbin exceeds about 2 V or more, such a booster is not necessary. This booster uses a transformer to boost the AC power.

The rectifier is a diode bridge rectifier circuit for converting AC power generated from the bobbin into DC power used in an electronic circuit.

The first DC-DC converter 33 is an AC-DC converter.
D of about 1.8 V supplied from the DC converter 32
It is used to increase the C voltage to about 3.6 V, which is the potential of the storage battery 36.

The first super capacitor 34 has the first
Is for temporarily storing the voltage supplied from the DC-DC converter 33 of FIG. The first supercapacitor 34 temporarily stores the power generated from the bobbin, and supplies the stored electric energy to the circuit of the electronic device for the operation of the electronic device (the circuit of the cellular phone), or The battery is supplied to the storage battery 36 for charging a secondary battery (particularly, a lithium ion battery).

If the power supply device of the present embodiment is applied to a cellular phone, the power used during a call standby is supplied from the first supercapacitor 34, and the power used during the call is actually supplied from a storage battery 36. Supplied. Such adjustment of the power supply is achieved by an internal microprocessor (not shown) of the second DC-DC converter 35. Thus, the use efficiency of the storage battery can be further improved by the first supercapacitor 34.

The second super capacitor 37 is provided for compensating the storage battery 36.
When an instantaneously high voltage (pulse voltage) is required in the external circuit, the stored power of the second supercapacitor 37 is supplied to the external circuit. Therefore, it is possible to prevent an excessive discharge that occurs instantaneously in the storage battery 36. As a result, the service life of the storage battery 36 is 1.5 to 2 times that of a normal case.
It is extended about twice.

The electric energy stored in the second supercapacitor 37 is supplied from the storage battery 36 and an external circuit, and is adjusted by the second DC-DC converter 35.

The supercapacitors 34 and 37 are not much different from existing general capacities. However, the super capacitors 34 and 37 are EDLC (Electric doule la
yercapacitor (electric double-layer capacitor), the chargeable capacity is about 1, compared to the existing capacity.
It has a much larger value, about 000 to 100,000 times.

That is, while the general capacity has a capacity of several μF to several hundred μF, the supercapacitor has a capacity of several hundred m.
It has a capacity of F to several F.

The second DC-DC converter 35 is used to increase the voltage of 3.6 V supplied from the first supercapacitor 34 to the level at which the circuit operates, ie, 4.0 to 4.2 V. You. Further, the second DC-DC converter 35 adjusts the voltage supplied from the first supercapacitor 34 so as to supply the voltage to an external circuit or to use the voltage as a power source for storing the storage battery 36.

As described above, the weak AC voltage generated from the bobbin is primarily converted into the DC voltage by passing through the charge adjusting circuit 30, and then is boosted to the charging potential of the secondary battery or the operating potential of the circuit. You.

Of course, the charge adjusting circuit 30 of the present embodiment is not necessarily limited to the circuit configuration example shown in FIG. That is, if the same function and result are expressed, various modifications are possible in the state of the art of those skilled in the art.

Further, the charge adjusting circuit 30 is implemented as an IC chip and mounted according to the trend of lightening of cellular phones.
opulate).

In the above-described embodiment, the case where one induced electromotive force generating means 17 is housed in the housing space 21 formed vertically on the outer surface of the secondary battery 13 has been described.

However, the induced electromotive force generating means 17 of the present invention
Can be built in a cellular phone, and a plurality of induced electromotive force generators can be connected in parallel as shown in FIG. Further, as shown in FIG. 5, it is also possible to arrange vertically and horizontally and connect them in parallel.

As described above, when a plurality of induced electromotive force generating means are connected in parallel, there is an advantage that the charging capacity is increased and the necessity of a separate power supply is reduced, but the weight of the cellular phone is increased. There are disadvantages.

The first embodiment of the present invention described above shows a case where the induced electromotive force generating means is fixedly installed on the back of a battery pack attached to a portable phone.

However, in this embodiment, the permanent magnet and the bobbin
Since parts having a considerable weight, such as springs, must be added to the cellular phone, it is not possible to effectively and properly cope with the demand for reducing the weight of the cellular phone.

Accordingly, a description will be given below of a new embodiment in which kinetic energy can be used as an energy source for charging a secondary battery without increasing the weight of a portable electronic device such as a cellular phone.

The portable power supply device 100 according to the present embodiment has a case 110. The case 110 has an upper storage chamber 113 and a lower storage chamber 115. The upper storage chamber 113 is sealed by an upper lid 112 having a detachable projection 121. Further, the lower storage chamber 115 is also hermetically sealed by the lower lid 114 having the detachable projection 141. The case 110 has attaching / detaching portions 122 and 142 for receiving the protrusions 121 and 141, respectively.

In the upper storage chamber 113, the magnet support plate 10 is provided.
5 and 105 'are arranged on both inner surfaces of the upper storage chamber 113 as shown in the figure, and the magnet support plates 105 and 105' are fixed to the bottom surface of the upper storage chamber 113 so as not to be detached toward the center. Fixed jaws 101, 10 for

2, 131 ', 132' and a concave portion. A bobbin 151 on which the coil 107 is wound is provided in a concave portion formed by the convex portions 131, 132, 131 'and 132' of the moving member.
152, 153, 151 ', 152', 153 'are fixed.

FIG. 10 shows a specific configuration of the bobbin 151.

As shown, a coil 107 is wound around the bobbin 151, and a hollow 108 for accommodating a magnet is formed inside the coil 107.

As will be described later, when the moving member 130 vibrates in its length direction, the bobbins 151, 152, 153, 151 ', 152',
153 'also vibrates at the same time. Thereby, the magnets 156, 157, 158, 156 '157', 15
8 'oscillates relatively toward or away from the bobbin. At this time, a change in magnetic flux is generated, and an induced electromotive force is generated at both ends of the coil 107 of the bobbin.

2, 131 ', 132' and magnet support plates 105, 105 '
And springs 161, 162, which are elastic members,
161'162 'are respectively interposed. The convex portion 13
Grooves are respectively formed in the front surfaces of the magnet support plates 1, 132, 131 ', and 132', and both ends of the springs 131, 132, 131 ', and 132' are buried therein. In the case of the present embodiment, the use of the coil spring as the elastic member is illustrated, but the present invention is not necessarily limited to this.

FIG. 11 is a plan view of the embodiment 100 after the upper lid 112 is removed.

The moving member 130 is arranged in the upper storage chamber 113 so as to have a gap with both wall surfaces of the upper storage chamber 113, and a spring 161 which is an elastic member is provided in the gap.
162, 161 'and 162' are interposed. Therefore,
If the case 110 is vibrated by an external motion,
The movement member 130 includes springs 161, 162, 16

Accordingly, the charge adjusting circuit 30 converts the AC voltage into a DC voltage, and then boosts the converted DC voltage to a certain voltage level and stores the boosted DC voltage in the supercapacitor 34. The supercapacitor 34 stores a weak induced voltage and partially supplies the circuit to a portable electronic device, and the remaining part is used to charge a secondary battery.

FIG. 12 shows a connection contact 142 for supplying a DC voltage from the charge adjustment circuit 30 incorporated in the circuit board 120 to the storage battery 170. The connection contact 142 is disposed in the lower storage chamber 115.
