JP2000023378A - Generator type battery pack for portable telephone set - Google Patents

Abstract

PROBLEM TO BE SOLVED: To further improve the operating ease of a generator type battery pack by providing an interface connector which can cope with each manufacturer, can be attached anew, and has compatibility with electrically-charged battery packs. SOLUTION: When the battery section 7 of a portable telephone terminal 1 runs down, an interface connector 2 having electrical and mechanical interchangeability with the external interface for charging of the terminal 1 is set up in a spring taking-up section 3, and the battery is charged by inserting the external interface of the terminal 1 into the connector 2. Since the lower section of the connector 2 is constituted as the spring taking-up section 3, the section 3 can be used while winding up the section 3, even when the terminal 1 is busy. Even when the terminal 1 is removed from the connector 2, in addition, the battery section 7 can be charged. Since the section 3 here has a structure with which a spring is not wound directly but is wound indirectly, the rotation of the section 3 in the reverse direction can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention charges a built-in battery by power generation by a firing method, and an interface connector connected to an external connector of a portable telephone can be replaced as necessary to correspond to each manufacturer. Further, the interface connector relates to a generator-type battery pack for a mobile phone that is compatible with an electric rechargeable battery pack.

2. Description of the Related Art In a conventional battery pack with a generator for a portable telephone, a rack is moved by pressing a lever in Japanese Utility Model Laid-Open No. 6-23162, and a spring is wound by a pinion gear with a ratchet, and the spring is wound up to some extent. It is disclosed that the self-excited DC generator turns and starts generating electricity.

[0003]

As described above, in the conventional generator-type battery pack for a portable telephone, a manual lever, a mainspring wound by the lever, and a gear when the mainspring is wound up to a certain extent are used. It is disclosed that it starts to move, and as a result, the self-excited DC generator turns and starts generating electricity. However, as a result of repeatedly examining the problem of how to provide an easy-to-use mobile phone generator for a user instead of a structure for generating power in this way, as a result of different mobile phones for different manufacturers, We focused on the interface connector connected to the external connector.

[0004] For example, when a user carries a generator-type battery pack and goes out with a plurality of friends, each person naturally owns a plurality of cellular phones of a plurality of manufacturers. Among them, when a friend's mobile phone ran out of battery, it could not be charged because the interface connector was different. In addition, since the structure of the interface connector of the electric rechargeable battery pack mainly used indoors and the structure of the interface connector of the generator type rechargeable battery pack mainly used outdoors are different, charging is performed using an adapter.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and it is an object of the present invention to provide a power generation system for a portable telephone capable of efficiently generating electric power by manual operation and charging the generated electric energy to a built-in rechargeable battery. In the mechanical battery pack, a replaceable interface connector is provided so as to be compatible with each manufacturer, and the interface connector provides a generator battery pack for a mobile phone compatible with the electric rechargeable battery pack.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating a state in which a mobile phone terminal is charged in a generator-type battery pack for a mobile phone according to an embodiment of the present invention. FIG. 2 is a diagram illustrating a mobile phone according to an embodiment of the present invention. It is a block diagram in the state where the mobile telephone terminal is charged to the generator type battery pack. In FIG. 1, reference numeral 1 denotes a mobile phone terminal, 2 denotes a detachable interface connector, 3 denotes a winding-up section, and 8 denotes an electric interface connector.
As shown in FIG. 1, when the mobile phone terminal 1 is out of battery, an interface connector 2 that is electrically and mechanically compatible with a charging external interface of the mobile phone terminal 1 is provided in the winding-up unit 3. Thus, the external interface of the mobile phone 1 is inserted and ready to be charged.

In FIG. 2, the same members as those in FIG. 1 are denoted by the same reference numerals. Reference numeral 6 denotes a power generation unit that generates power by winding up the beam of the beam winding unit 3; 5, an AC detection unit that detects an electromotive force generated by the power generation unit 6; 4, a charge circuit unit; and 7, a charge battery unit. I have.

The operation will be described with reference to FIGS. 1 and 2. The interface connector 2 shown in FIG. 1 can be replaced so as to correspond to each manufacturer. The interface connector 2 is inserted from the bottom of the mobile phone terminal 1 to supply power. The lower portion of the interface connector 2 is a sprung winding unit 3 which can be used while winding the sprung winding unit 3 even during a call with the mobile phone terminal 1. Further, even when the mobile phone terminal 1 is detached from the interface connector 2, FIG.
Can be charged to the charging battery unit 7 indicated by.
In addition, since the sprung winding portion 3 does not directly wind the sprout but indirectly winds the sprung, the sprung winding portion 3 can be prevented from rotating in the opposite direction.

Next, an operation from power generation by winding up to charging of the power generation will be described with reference to FIG. The rotation speed of the spring is increased by performing the winding operation of the winding-up unit 3, the power generation unit 6 is moved, and the electromotive force generated by the power generation unit 6 is detected by the AC detection unit 5. Then, the electromotive force is charged to the charging battery unit 7 via the charging circuit unit 4, and the charged electromotive force is charged to the mobile phone terminal 1 through the interface connector 2.

If the interface connector 2 is compatible with the interface connector 2 used in the electric rechargeable battery pack 8, the single interface connector 2 can be used indoors and outdoors.

[0011]

As described above, the present invention is compatible with an electric rechargeable battery pack, and furthermore, has a replaceable interface connector provided on a rechargeable battery for winding operation which is compatible with each manufacturer. Since the battery can be charged regardless of the maker of the device, an easy-to-use charger can be provided.
