Figure 1 is a view showing the appearance of a smartphone auxiliary battery sold in the market.

The secondary cell refers to a battery capable of converting and storing electrical energy into chemical energy and then reconverting and using electrical energy when necessary, and is commonly referred to as a rechargeable battery 301. This rechargeable battery 301 can be charged by the auxiliary battery 25 and the charger, and thus can be repeatedly used several times. In recent years, as the demand for portable electronic products such as smartphones 5 or tablet PCs has rapidly increased, research on a high-performance rechargeable battery 301 capable of repetitive charging and discharging has been actively conducted. There is an increasing demand for an auxiliary battery 25 capable of supplying power to portable home appliances anytime, anywhere. However, in the case of the auxiliary battery 25 sold on the market, there is a problem of having to charge in advance in advance, and there is a disadvantage that it is difficult to be properly used in an emergency situation. This is because charging time must be considered in advance.

Figure 2 is a diagram showing a graph included in the report on the market trend of Japanese batteries provided by KOTRA.

In the graph of Figure 2, it is worth noting 2011. In the overall context of the graph, the demand for primary batteries is on a decreasing trend, but it is known that the usage is still high. In addition, according to KOTRA, the market size of the battery 201 in Japan was recorded as the highest at 115.3 billion yen in 2011, which is interpreted as an increase in the use of devices such as portable lights in emergency situations due to the impact of the Great East Japan Earthquake.

It can be seen from the graph of FIG. 2 that the use of a battery that does not require charging in advance is more suitable than the use of the rechargeable battery 301 in an emergency situation represented by a disaster situation. In addition, the battery 201 is still in demand as a suitable battery when it is necessary to conserve energy for a long time, such as a table clock, a remote control, or a hearing aid.

FIG. 3 is a diagram showing a use of a portable charging device sold on the market.

The battery 201 is cheaper than the rechargeable battery 301 and has the advantage of being able to easily purchase anytime, anywhere. Therefore, when the battery must be suddenly used, it can be used more efficiently than the rechargeable battery 301. In addition, the battery 201 is still in constant demand in that it can be easily purchased and used compared to the rechargeable battery 301 and has almost no risk of explosion. Considering this, a portable charging device 35 using a battery 201 is being sold on the market. However, in the case of a charging device using only the battery 201, there is a problem that it is difficult to reuse and causes an environmental problem.

Accordingly, it is necessary to develop an invention in which the battery 201 and the rechargeable battery 301 can be flexibly used in consideration of the steady demand for the battery 201 and the advantages of the rechargeable battery 301 that can be reused. However, the battery 201 and the rechargeable battery 301 need to be used separately. In general, the charger cannot use the battery 201 and the rechargeable battery 301 together. When the battery 201 and the rechargeable battery 301 are used together, there is a possibility of damaging the battery and circuit due to the difference in rated voltage, and in severe cases, damage to the smartphone or other electronic products connected to the battery may be caused. .

7 is a view showing a state that the reed switch, which is a component of the present invention, changes according to the application of magnetic force.

The reed switch 150 is composed of a pair of ferromagnetic materials, and the lead wires 155 may be formed in a state of being superimposed side by side with a small distance. The dotted line expressed around the magnet 250 in FIG. 7 represents the range of magnetic force for a preferred description of the present invention, and the range of magnetic force that can affect the operation of the reed switch 150 is (F) in the drawing. It was named as. When the lead wire 155 is positioned within the range of the magnetic field, the lead wire 155 is magnetized with opposite polarities, attracts each other, and closes the contact point so that the switch is turned on. That is, when the magnetic force inside the reed switch 150 is generated, the lead wire 155 inside the reed switch 150 has a polarity opposite to each other of the negative electrode and the positive electrode, and thus attracts each other to drive the switch.

When the magnetic force disappears, each of the lead wires 155 returns to its original position by elasticity, and the switch is turned off, that is, the lead wire 155 is separated and thus no current flows. If lead wires having the same polarity are present, the lead wires 155 push each other and stop the application of current according to whether or not magnetic force is applied.

FIG. 16 is a diagram showing a state in which an automatic transfer circuit using a reed switch is driven according to whether a battery and a rechargeable battery are inserted in the second embodiment of the present invention.

For a preferred description of the automatic transfer circuit 100 using the reed switch according to the second embodiment of the present invention, a driving process of the automatic transfer circuit 100 using the reed switch of FIG. 9 will be described with reference to (1a). In addition, the drawings of (1a) and (2b) will be divided into (A), (B), and (C) according to whether the battery 201 and the rechargeable battery 301 are inserted as described in FIG. 9.

The driving process of the second embodiment of the present invention, which will be mainly described in FIG. 16, is shown by (2b) in FIG. 16. (1a) and (2b) of Fig. 16 are different in the type of the reed switch 150. First, (1a) is a NO reed switch 150a. When magnetic force is transferred into the reed switch 150, the lead wires 155 having different polarities are joined to each other to drive the reed switch 150 In the NC reed switch 150b of (2b), when magnetic force is transmitted to the inside of the reed switch 150, the lead wires 155 having the same polarity push each other, and the left lead wire 155a and the right lead wire ( 155b) may be broken.

Therefore, when comparing (A) of (1a) and (2b) of Fig. 16, the reed switch 150 of (1a) is short-circuited to apply current from the rechargeable battery holder 301 to the power output terminal 700, The reed switch 150 of (2b) is in a state in which magnetic force is not applied to the lead wire 155 constituting the reed switch 150, that is, the magnet 250 is separated from the reed switch 150 by a predetermined distance or more, but the lead wire The original positions of 155 are configured so as not to be separated from each other, so that current can be applied from the rechargeable battery holder 301 to the power output terminal 700.

The following will be described by comparing (C) of (1a) and (2b). In the case of (1a), as in (B), the magnetic force is not applied because the transfer magnet is spaced apart, but it differs from (B) in that a rechargeable battery is provided. However, regardless of whether the rechargeable battery 301 is inserted, the automatic transfer circuit using the reed switch according to the present invention has a difference in the driving process only if it is inserted into the battery 201, and (C) of (1a) is (B) of (1a). Like ), since magnetic force is not applied to the inside of the reed switch 150, the lead wire 155 does not come into contact with it, so that current cannot be applied.

On the other hand, in the case of (2b), magnetic force is applied by the magnet 250, but when the magnetic force is applied, the lead wires 155 configured inside the reed switch 150 are pushed together by the same polarity, and accordingly, the reed switch 150 There is a difference in that it is configured so that current from the rechargeable battery 301 cannot be transmitted to the power output terminal 700 by being blocked.

As in (B) of (1a), since magnetic force is not applied to the inside of the reed switch 150, the lead wire 155 does not come into contact, so that current cannot be applied. The driving process of the modified embodiment of the automatic transfer circuit using the reed switch according to the first and second embodiments of the present invention according to FIG. 17 is described in the first and second embodiments of the present invention according to FIG. 2 It can be seen that there is no difference from the embodiment. However, it can be seen that the automatic transfer circuit 100 using a reed switch according to a modified embodiment of the present invention has no difference in a driving process depending on whether a rechargeable battery and a battery are inserted.

On the other hand, in the case of (2b), magnetic force is applied to the lead wire 155 inside the reed switch 150 by the magnet 250, but when magnetic force is applied, the lead wire 155 configured inside the reed switch 150 has the same polarity. By pushing each other, there may be a difference in that the reed switch 150 is blocked accordingly so that the current from the rechargeable battery 301 cannot be transmitted to the power output terminal 700.

Here, the open state of the reed switch 150 refers to a state in which the lead wire 155 provided in the reed switch 150 returns to its original position by elasticity. The state in which the lead wire 155 returns to its original position due to elasticity is achieved because the magnetic force of the magnet 250 provided in the battery holder 200 does not reach the reed switch 150 during the insertion of the battery 201. I can lose. This is described on the basis of the first embodiment of the present invention having the NO-type reed switch 150a, and the automatic transfer circuit 100 using the reed switch is provided with the NC-type reed switch 150b. 2 In the case of the embodiment, the step of opening the reed switch 150 when the battery 201 is inserted (S18-3) is that the magnetic force of the magnet 250 provided in the battery holder 200 is applied to the reed switch 150.

In other words, the reed switch 150 does not receive magnetic force from the magnet 250, so that the lead wire 155, which is a component inside the reed switch, is originally due to elasticity. It returns to the position of and can cause a short circuit. Although there may be differences in the process of short circuiting, the order of switching when the battery 201 is removed is the same regardless of the first embodiment and the second embodiment and/or the modification of the first embodiment and the modification of the second embodiment.
