Abstract

The present invention, when using a portable communication device such as PDA and mobile phone (hereinafter referred to as a telephone), when the battery attached to the telephone is almost exhausted and an alarm sounds, the battery remains connected without stopping or turning off the call. Provides the ability to exchange.

In the representative diagram, when the battery level indicator attached to the main unit shows the lowest level or the alarm sounds, the user double-clicks a specific key button promised on the telephone. Will cause the connection to be released. At this time, when the user replaces the charged battery with the consumed battery and double-clicks a specific key button, the power supply line of the phone is connected to the newly installed battery and separated from the internal battery, thereby completing the battery replacement work. If the capacity of the built-in battery is below a certain level, it is automatically charged from the main battery or the battery charger.

Description

Uninterruptible battery exchange system of mobile communication device {Battery exchanging system without disconnection for mobile-communication-equipment}

The present invention relates to a method of exchanging a battery while maintaining a call connection when the battery is exhausted and replaced while using a PDA or a mobile phone (hereinafter, referred to as a portable communication device).

In the conventional mobile phone, when the battery is exhausted during the call and falls below the reference voltage 8, the voltage comparator 9 detects this, and the microprocessor 11 outputs a beep signal for ringing the buzzer 12. After that, when the battery voltage falls below the threshold value, the output of the microprocessor (ⓒ) is designed to stop the call by blocking the power switch 13. In addition, when the alarm sounds 'low battery' in the standby state, the user voluntarily turns off the power, replaces the battery with a charged battery, and logs in again. However, this natural procedure could sometimes undermine a conversation with an important party, or make it difficult to contend for a minute. This conventional approach was inevitably taken for granted, but it was clearly a problem that needed improvement.

In order to solve the above problems, the present invention, when the user of the mobile phone recognizes that the exhaustion of the battery is imminent during the call or standby, the specific key button of the phone (for example '#' key or '*' key) The purpose of this function is to provide a function to replace the battery while maintaining a call connection by double-clicking).

Figure 2 is a circuit diagram of the power supply unit of the mobile phone improved in the present invention.

* Explanation of Signs of Major Parts of Drawings *

1: mobile phone

2: Mounting battery (secondary battery, main power)

3: built-in battery (secondary battery, auxiliary power)

4: replacement battery (secondary battery)

5: Battery connection terminal

6: electronic switch (b contact)

7: Electronic switch (a contact)

8: reference voltage

9: voltage comparator

10: Key button designated by program

11: microprocessor

12: alarm (alarm buzzer)

13: power switch

14: germanium diode

The present invention for achieving the above object is to install a small battery (3) inside the mobile phone (1) for the purpose of preventing a call interruption, opening and closing the main battery (2) and the internal battery (3) To add a semiconductor switch (6), (7), the microprocessor 11 provides a function of the present invention by controlling them with a program.

Hereinafter, the uninterruptible battery exchange system according to the present invention will be described in detail with reference to the accompanying drawings.

If the user recognizes that the remaining battery capacity of the mobile communication device is insufficient and attempts to replace the battery with a new battery 4, first, the promised key button 10 of the phone; For example, double click the '#' key. The microprocessor 11 which senses this signal outputs a command to turn on the semiconductor switch a contact 7 at the output terminal ⓐ and to turn off the semiconductor switch b contact 6 at the output terminal ⓑ. After that, the main battery 2 mounted on the phone is disconnected, and power is supplied from the built-in battery 3 so that the phone can maintain a normal operating state.

The user replaces the charged battery 4 with the depleted battery 2 and mounts it.

Double click on the promised key button 10. Upon receiving this signal, the microprocessor 11 returns the semiconductor switch a contact 7 and b contact 6 to an initial state, whereby the replacement operation is completed.

The present invention is basically possible to replace the battery while maintaining the connection, but if you use the earphone, you can easily replace the battery while continuing the call.

If you are busy only talking without pressing the return button after replacing the battery, program the two electronic switches (6) and (7) to return to their original state automatically after the set time (for example, 2-3 minutes). Do it.

Looking at the effect of the improved mobile phone according to the present invention, it is possible to avoid the interruption of connection due to lack of battery during the call can ensure communication safety in emergency standby service, emergency communication, etc. It will be effective in preventing the loss of the loss, avoiding a rude in the call with the adults on the hand, and eliminating the possibility of misunderstandings due to the interruption of the call between friends and lovers. In addition, you can expect psychological stability as the battery can be replaced without turning off the phone.

Claims (1)
