DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery output recovery device for recovering the output of a primary battery once used in many home electric appliances and the like, once the output of the primary battery is cut off.

[0002]

2. Description of the Related Art At present, primary batteries such as manganese dry batteries, alkaline dry batteries, mercury batteries, and lithium batteries are used as power supplies for a wide range of electrical devices such as home appliances, measuring instruments, and communication devices. Representative examples of electric devices using a primary battery include a remote control device such as a television receiver, an intercom, a camera, a calculator, a clock, a mobile phone, and the like.

[0003] Since the chemical reaction in the battery occurs irreversibly, the primary battery has a life if it changes by discharging a chemical substance participating in the chemical reaction. That is,
Primary batteries are non-rechargeable batteries. Generally, therefore, it is considered that when the operation of the electric device stops due to the power supply during use, the battery has run out, that is, the chemical substance in the battery has been exhausted and has reached the end of its life. Then, in order to restart the electric equipment, the user replaces the battery with a new one stored in the battery, or runs to buy a new battery when there is no stock.

[0004]

As described above, in the case of an electric device using a battery as a power source, there is a problem that the device stops because of the life of the battery as the power source. In recent years, although the life of the primary battery has been greatly improved, it is inevitable that the operation of the electric device stops due to the life of the battery. However, power can be restored as quickly as possible, such as with devices that are being used frequently, such as remote control devices and mobile phones, and that are moving or measuring continuously. desired.
In addition, in consideration of the case where the vehicle is moving, it is desirable that the battery output can be recovered without replacing the battery.

[0005] When investigating the cause of the cut-off of the battery as a power source, it is not necessarily the life as a result of the chemical substances in the battery being completely changed by the discharge, but the electromotive force due to the partial increase in the internal resistance of the battery. It was considered that the output was lowered, which caused the output to stop. The present invention has been made in view of the above-described problems, and provides an apparatus capable of reactivating a battery and quickly restarting an apparatus when the output of the battery is cut off, particularly without replacing the battery. It is intended to be.

[0006]

The present invention has the following features to attain the object mentioned above. That is, the battery output recovery device of the present invention is a battery output recovery device for recovering the output of the battery for an electric device whose power supply to the load is a battery, and one of the positive and negative electrodes of the battery. A switch having one end connected to the other end, a switch for conducting and breaking between the other end of the resistor and either the positive or negative electrode of the battery , and a switch for manually conducting and breaking the switch.
And a switch drive mechanism (30) .

When the switch is turned off, the battery is discharged to the load. On the other hand, when the switch is turned on, the battery is short-circuited across the resistor. Then, by continuously repeating conduction and interruption by switching the switch, the output of the battery whose output has been cut off is restored again.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As a preferred embodiment of a battery output recovery device according to the present invention, a remote control device (hereinafter abbreviated as "remote control device") for a television receiver using a primary battery as a power source is described below. An example in which the battery output recovery device is applied will be described with reference to the drawings. FIG. 1 is a main part circuit diagram of a remote control device provided with a battery output recovery device according to the present invention. In FIG. 1, reference numeral 1 denotes a battery, reference numeral 2 denotes a load, reference numeral 3 denotes a main switch for supplying and shutting off battery power to the load, and reference numeral 4 denotes a battery power recovery device according to the present invention. Here, load 2 indicates the load of the main circuit of the remote control device. When the switch 3 is closed, electric power from the battery is supplied to the remote controller, and the remote controller operates.

As shown in FIG. 1, the battery output recovery device 4 of the present invention comprises a resistor 7 and a switch 6 connected to one electrode of the battery 1. When the switch 6 is closed with the main switch 3 closed, the battery is short-circuited via the resistor 7. That is, the output recovery device for the battery 1 of the present invention includes the battery 1, the main switch 3, and the switch 6.
And a short circuit including the resistor 7.

FIG. 2 shows the configuration of the battery output recovery device 4 of the present invention. The two batteries 1, 1
The positive electrode terminal 8 is brought into direct contact with the conductor 11 and the conductors 12 and 13 provided therein, and the negative electrode is inserted and connected by coming into contact with the conductor 9 via a spring 9. The conductor 11 connects one of the two batteries 1 in series. The conductor 12
Is a positive electrode of the battery, and the conductor 13 is a negative electrode terminal of the battery. The lead 15 from the negative electrode 13 is connected to the load 2 of the remote controller via the contact 16.

On the other hand, lead wire 20 from positive electrode terminal 12
Are connected to the column 21 via the main switch 3. A movable contact piece 22 made of a spring material is attached to the support 21, and is usually connected to a contact 23. Then, the contact 23 is connected to the load 2 of the remote control device, and supplies power from the battery to the load 2.

A contact 24 is provided opposite to the contact 23, and the contact 24 is connected to the contact 16 connected to the negative terminal 13 of the battery via the resistor 7. Normally, the movable contact piece 22 is connected to a contact 23, and the switch 3
Is closed, the battery power is supplied to the load 2. However, when the movable contact piece 22 is switched to the contact point 24, the power supply to the load 2 is cut off to form a short circuit through the resistor 7, and the short circuit includes the electromotive force of the battery and the resistor 7. A fixed short-circuit current flows.

As shown in FIG. 2, the movable contact piece 22 normally connected to the contact 23 is switched between the contact 23 and the contact 24 by a switch driving mechanism. The switch drive mechanism is composed of a rotary operation plate 30 supported by a central shaft 31 and having four pins 32 projecting from the back surface thereof. A hole 35 is formed in the rotary operation plate 30, and a finger is inserted into the hole 35 to rotate the rotary operation plate 30.

As the finger is inserted into the hole 35 of the rotary operation plate 30 and rotated, one pin 3 on the back surface of the rotary operation plate 30 is rotated.
2 presses the movable piece 22, and the movable piece 22
And contacts the contact 24. As the rotation further proceeds, one pin 32 that pushes the movable contact 22 is
The movable contact piece 22 is separated from the contact 2 by its elastic force.
Return to 3. Further, when the rotation operation plate 30 rotates, the next pin 32 pushes the movable contact piece 22, the connection is switched from the contact 23 to the contact 24, and when the pin is released, the movable contact piece 22 comes into contact with the contact 24. I do.

By rotating the rotary operation plate 30 in this manner, the connection between the contacts 23 and 24 is continuously switched. When the movable contact piece 22 connects the support 21 and the contact 23, the output from the battery is supplied to the load 2. When the movable contact piece 22 connects the support 21 and the contact 24, the battery enters a short-circuit state via the resistor 7. Since the above-described resistor 7 has a sufficiently small resistance value as compared with the resistor as a load, the resistor 7
The battery current flows in the short-circuit state via the.

The operation of the battery output recovery device having the above configuration is performed as follows. When the output of the battery serving as the power supply is cut off and the remote control device does not operate, the back cover (not shown) containing the battery output recovery device 1 of the remote control device is removed, and a finger is inserted into the hole 35 of the rotary operation plate 30. , And the rotation operation plate 30 is rotated. By the rotation of the rotation operation plate 30, the pin 32 functions as a cam, and the movable contact piece 22
As the rotary operation plate 30 rotates, the contact 23 or the contact 2
The connection is switched to 4 and the state is repeatedly switched to the state of discharging to the load or the state of short circuit via the resistor 7. By repeating the switching between the discharge state and the short-circuit state 10 to 20 times (that is, rotating the disk 20 several times),
The output of the battery once output is cut off is restored.

The mechanism of battery output recovery by the battery output recovery device is not always clear. However, it is believed that the battery output is recovered by the mechanism described below. Generally, when a battery is discharged, polarization causes internal resistance. When the discharge to the load continues, the internal resistance gradually increases, and at the same time, a portion having a large electric resistance is generated somewhere in the battery. For this reason, the electromotive force is reduced, and the battery voltage required for supplying the output to the load cannot be obtained, and the battery current does not flow.
This is presumed to be that the reaction of the ionic species in the battery at the electrode was prevented, or the movement of the ionic species was blocked in a part of the battery and no electromotive force was generated. A large battery current flows by short-circuiting both electrodes of the battery. Therefore, it is considered that by recovering the speed of the electrode reaction and promoting the movement of the ion species whose movement has been prevented, the electric resistance in the battery is homogenized and the battery output is recovered.

In the above-described embodiment, an example has been described in which the battery output recovery device including the battery 1, the main switch 3, the switch 6, and the resistor 7 is built in the electric equipment. However, it is possible to use not only a built-in battery, but also an independent battery recovery device having a resistor 2 corresponding to a load and a battery insertion portion 10 and having the same configuration as that shown in FIG. . In this case, the battery whose output has run out can be inserted into an independent battery recovery device, and the battery output can be recovered by switching the switch a plurality of times, and can be returned to the original electrical device and reused.

Except for the battery insertion portion, all other components may be the same as the independent battery output recovery device described above. In this case, the positive electrode of one battery is
2 and the ends of the lead wires 15 and 20 of FIG.
13, and the output of the battery can be recovered by continuously switching the switch a plurality of times.

The battery whose output has been restored by the battery output restoring device as described above can be used for a considerably long time thereafter. Therefore, by incorporating the present battery output recovery device into a home electric appliance, the time during which the use of the device becomes unavailable due to the output of the battery can be suppressed in a very short time.

Further, even when a spare battery is not prepared, the battery output can be immediately restored and the device can be continuously operated. Further, since the battery output recovery device can manually recover the output, it does not require an external power supply and can immediately recover the battery output in any place.

[0022]

As described above, the battery output recovery device of the present invention is incorporated in an electric device, for example, a remote control device of a television receiver. A switch is provided for turning on and off the other end of the resistor and the other of the positive and negative electrodes of the battery. When the switch is turned on and off, the battery is switched between a discharge state to the load and a short-circuit state across a resistor. The output of the battery whose output has been cut off can be recovered by repeating the switching of the state as described above ten times or more.

The battery whose output has been restored by the present battery output restoring device can then be used for a long period of about one month in the case of a remote control device, for example. Therefore, by incorporating the present battery output recovery device into a home electric appliance, the time during which the use of the device becomes unavailable due to the output of the battery can be suppressed in a very short time.

Further , the present battery output recovery device can repeatedly switch the conduction and cutoff of the switch.
As the switch driving mechanism, for example, a rotary operation plate provided with pins on its surface is provided. Therefore, by turning the rotary operation plate with a finger inserted therein, it is possible to quickly switch between conduction and cutoff. Therefore, the battery output can be recovered in a very short time. Further, since the present battery output recovery device is manually operated, the output of the battery can be easily recovered at any place at any time, and the use of the electric equipment can be continued. Further, by using the battery output recovery device, it is possible to extend the use period of the primary battery that has been discarded because the output has not been obtained only once.
