Description

Shared charging device using transistor

The present invention relates to a shared charging device using a transistor for sharing a cell-type rechargeable Ni-MH (Metal Hydride) battery and a general alkaline battery together using a transistor.

According to the general prior art, since there is no charging unit in the main body, the rechargeable battery uses a battery charged in a set or charged in a separate charging device or uses a general battery.

That is, there is a charging unit in the main body and a charger and a general battery identification unit, but the rechargeable battery has a different shape from the general battery (slim, rectangular, cylindrical) and accordingly, each battery insert is separate, and in the case of rechargeable batteries according to make Because of its unique method, the type of batteries used is limited depending on the set.

The prior art uses a general-purpose battery, there is a problem in that the user's battery utilization is limited and somewhat inconvenient because a separate charging device is required when using a rechargeable battery in common.

The present invention has been made to solve the above problems, it is possible to simply configure the circuit with a transistor and to use a common battery and a rechargeable battery in common, so that the user can use general or charging without using a separate charging device It is an object of the present invention to provide a shared charging device using a transistor that enables a common use of a rechargeable battery.

The present invention is used in a system operated with a general purpose or rechargeable battery to detect the rechargeable battery and prevent overcharging of the battery and output corresponding control signals, and install the general or rechargeable battery in the system. Battery mounting unit for supplying power, indicating the type of battery in response to the control signal of the battery mounting unit, the display and supply unit for applying the power of the battery mounting unit, switching unit for cutting off or applying the power receiving the control signal of the battery mounting unit And a charging unit configured to charge the power of the switching unit to the rechargeable battery mounted in the battery mounting unit and stop charging according to a control signal of the battery mounting unit, and apply to a cell-type battery and all devices requiring charging. Cost savings by using simple circuits and fixtures There is an effect, and has the feature of providing the user with the convenience of common battery.

Hereinafter, the shared charging device using the transistor according to the present invention will be described in detail.

1 is a block diagram showing a shared charging device according to the present invention, Figure 2 is a circuit diagram showing a shared charging device according to the present invention in detail, Figure 3 is a cross-sectional view showing a battery mechanism of the shared charging device according to the present invention. .

According to the present invention, as shown in Figure 1, by detecting the rechargeable battery and prevents overcharging of the battery to output the corresponding control signals, and to supply the power to the system by mounting the general or rechargeable battery Receiving the control signal of the battery mounting unit 10, the battery mounting unit 10, and displays the type of battery, the display and supply unit 20 for applying the power of the battery mounting unit 10, the control of the battery mounting unit 10 Switching unit 30 to cut off or apply AC / DC power in response to the signal, the AC / DC power of the switching unit 30 is charged to the rechargeable battery mounted on the battery mounting unit 10 and the battery mounting unit 10 It consists of a charging unit 40 to stop charging according to the control signal of the).

As shown in FIG. 2, the switching unit 30 includes a resistor and a MOS FET Q1, and the display and supply unit 20 includes a transistor Q2 and a light emitting diode L. do.

In addition, the battery mounting unit 10, as shown in Figure 3, the instrument 50 for mounting the rechargeable battery, and is formed on one side of the instrument 50 outputs a stop charge control signal to prevent overcharge The first terminal TH, the second terminal BAT for outputting a control signal indicating that the rechargeable battery is installed, the power terminals (+,-) for outputting the power of the battery, and the second terminal BAT. And a wire 60 electrically connecting the power terminal (-), and an elastic support (not shown) to elastically support the side to prevent the flow of the apparatus 50.

Referring to the operation according to the present invention configured as described above are as follows.

First of all, rechargeable and general batteries are basically the same in appearance.

Therefore, the rechargeable battery is placed in the mounting unit 40 in the instrument 50, the general battery is mounted without the instrument.

In this case, the first terminal TH and the second terminal BAT are opened so that no signal is transmitted to the switching unit 30 and the charging unit 40.

In this way, the classification of the general, Alka and filling is divided according to whether the instrument 50 is mounted, the volume is increased when the instrument 50 is installed, so to eliminate the flow when installing the general battery plate spring, etc. Support by being elastic and solve

When the rechargeable battery is inserted into the battery mounting unit 10 in such an environment, a control signal indicating that the rechargeable battery is mounted from the two terminals BAT of the mounting unit 40 is output to the switching unit 30.

In addition, the control signal is output to the display and supply unit 20 to inform the outside as a light emitting diode (L) that the rechargeable battery is mounted on the mounting portion (40).

The switching unit 30 transmits AC / DC power supplied from the outside using the control signal as an enable signal, and converts it to have a potential difference within 5V and then outputs it to the charging unit 40.

Subsequently, the charging unit 40 checks the state of charge of the rechargeable battery while charging the power inside and outside the 5V to the rechargeable battery of the battery mounting unit 10, and when the battery is fully charged, the battery mounting unit 10 The control signal for preventing overcharging is output to the charging unit 40 at the first terminal TH.

At this time, the charging unit 40 cuts off the power to charge the rechargeable battery by the control signal.

As such, when the charging operation is completed, the voltage output from the power terminals (+,-) of the battery mounting unit 10 allows the system to operate through the display and supply unit 20.

If the general alkaline battery is mounted in the battery mounting unit 10, the mounting unit 40 transmits a control signal indicating that the rechargeable battery is not mounted to the switching unit 30 and the display and supply unit 20.

Then, while the switching unit 30 blocks the external AC / DC power from being applied to the charging unit, the display and supply unit 20 displays that the general purpose battery is installed.

Therefore, the charging operation that occurs in the charging unit 40 does not occur.

The operation of the system using the general purpose dry battery as power is output from the power supply terminals (+,-) of the mounting unit 40, the power of the common battery in the battery mounting unit 10 through the display and supply unit 20 It is supplied to the system and is made by the supplied power.

The configuration that is not described herein includes the MOS FET Q1 of the switching unit 30, the transistor Q2 of the display and supply unit 20, the mechanism 50 and the wire 60 of the battery mounting unit 10. to be.

The common charging device using a transistor according to the present invention can be avoided from the danger of fire, etc. when charging under the mounting of a general battery, and it is possible to use a rechargeable battery without using a separate charging device. The charging state can be checked for stable charging.

Therefore, it can be applied to cell-type batteries and all devices requiring charging, and there is a cost reduction effect by using a simple circuit and a device, and it is effective to provide a user with the convenience of using a common battery.
