This invention is applicable to portable electronic devices with an optional replaceable battery adapter. related.

0002

[Conventional technology]

In the field of personal computers, replacing the traditional disk top type, Laptops, which are small, lightweight, and convenient to carry, have become popular. This kind of person Due to their characteristics, most computers are powered by batteries, which saves energy. Empowerment is considered the most important design issue.

0003 A laptop-type personal computer powered by the above-mentioned secondary battery. If the built-in battery capacity decreases, the battery will be supplied with AC power via the AC adapter. It was charged and used using the supplied electricity.

0004

[Problem that the idea aims to solve]

As mentioned above, conventionally, when the capacity of the built-in battery decreases, it can be used in places without AC power. The problem is that a personal computer cannot be used without an AC adapter or an AC adapter. was there.

[0005] This idea was made in view of the above circumstances, and if the capacity of the built-in battery decreases, A portable electronic device equipped with a power supply that allows continuous use even in locations without AC power. The purpose is to provide equipment.

[0006]

[Means to solve the problem]

The portable electronic device of the present invention is powered by an AC adapter in addition to the built-in battery. It consists of the main body of the electronic device to be supplied and a battery adapter. A replaceable primary battery that serves as a power supply source as an alternative to a power source, and A regulator that converts the current and voltage required for the A switch to cut off the connection between the battery and regulator, and an AC adapter included in the electronic device itself. and a connection plug that connects to the data input terminal.

[0007]

[Effect]

In the configuration of the present invention described above, the low battery state of the built-in battery of a portable electronic device is When the condition is detected, attach the battery adapter to the AC adapter connection plug. for example , when using the personal computer outdoors, use an external battery with a power supply terminal ( By replacing the battery adapter, you can use your personal computer for long periods of time. Realize. This allows you to use it as an alternative to the AC adapter even if the built-in battery capacity decreases. Continuous use is possible by attaching the battery adapter to the battery.

【Example】

An embodiment of the present invention will be described below with reference to the drawings.

[0009] FIG. 1 is a perspective view showing an embodiment of the present invention.

0010 In FIG. 1, 1 is the main body of a personal computer. 2 is AC adapter This is an input terminal and a terminal for charging the built-in battery of the main unit. 3 is the main idea The gist of the proposal is the battery adapter. The detailed configuration of this battery adapter 3 is shown in Figure 2. shown. 4 is an AC adapter, which is usually connected to AC adapter input terminal 2. , converts the AC power into the DC power required by the personal computer main body 1, and Supplies the DC power necessary for operation. 5 is the primary voltage set in the battery adapter 3. It's a pond.

[0011] FIG. 2 is a diagram showing the internal configuration of the battery adapter 3 shown in FIG. 1. In the figure, 3 Reference numeral 1 denotes a primary battery, which corresponds to the primary battery 5 in FIG. 1 and can be replaced as desired. 32 is a voltage regulator, which is the AC adapter input of the personal computer main unit 1. Supplies the necessary power to the personal computer main unit 1 when connected to the terminal 2. Ru. 33 is the connection between the primary battery 33 (5 in Figure 1) and the voltage regulator switch 32 It is a switch inserted in the circuit, and is turned off when not in use or when replacing the battery. (off) state. 34 is a connection plug, which connects the personal computer main body 1 is connected to AC adapter input terminal 2 of.

0012 The operation in the embodiment of the present invention will be explained below.

[0013] The personal computer main body 1 is powered by a secondary battery. This secondary battery is The structure is always non-removable. Usually, the personal computer main body 1 When using in an office etc., connect AC adapter 4 to AC adapter input terminal 2. DC power is supplied to the personal computer main body 1. In this way, the AC power supply In places where power supply equipment (AC outlet) is available, the product may become unusable mid-way due to a dead battery. There is no problem with it disappearing. However, when using the AC adapter outdoors, etc. In environments where there is no Usage time is limited by battery capacity.

[0014] The present invention solves this problem by connecting the battery adapter 3 to the AC adapter. Connect to the input terminal 2 instead of the AC adapter 4, and use a commercially available primary battery (for example, a single or By inserting AA or AA batteries, you can power the personal computer 1. It is possible to supply power and significantly (optionally) extend the usage time. i.e. battery By using the built-in secondary battery only when replacing the battery of adapter 3, it can last for a long time. Therefore, the personal computer main body 1 can be used.

[0015] Note that the output power of the battery adapter 3 is connected to the personal computer via the AC adapter input terminal 2. By configuring the computer body 1 to be able to supply power to the built-in secondary battery, AC It is also possible to charge the secondary battery without using the adapter 4.

[0016]

[Effect of the idea]

With the above-described configuration, even if the built-in battery capacity decreases, the AC adapter remains Continuous use is possible by attaching a battery adapter instead of a battery. This allows you to run your personal computer for long periods of time without using an AC adapter. data can be used.
