Abstract

PROBLEM TO BE SOLVED: To simplify a structure, to reduce the cost and to make it easily replaceable, by providing a magnet attracted by magnetic attraction on each mounting surface of a battery pack body containing a battery inside and an electronic apparatus to receive power from the battery pack for mutual attraction. SOLUTION: The body 3 of a battery pack 7 having an electrode 6 for a charging terminal to be electrically connected to a charger is mounted to an electronics apparatus body 1 such as a mobile phone with an electrode 2 protruded at the designated spot. In this case, waterproof and frame-shaped first and second magnetic sheets 4, 5 mounted to the battery pack body 3 and the electronic apparatus body 1 are attracted each other by magnetic attraction. As a result, in the electronic apparatus body 1 and the battery pack body 3, the electrodes 2, 6 are electrically and elastically connected each other and liquid- tightness is materialized, and water and the like never infiltrate into the electrodes 2, 6. Thereby, the electrical connection of the electrodes 2, 6 is not damaged by moisture, and the battery pack can be easily mounted and demounted with a simple structure.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a battery pack which is mounted on an electronic device such as a portable telephone device main body and supplies power to the portable telephone device main body.

[0002]

2. Description of the Related Art Recently, various types of electronic devices, for example, portable telephone devices, are small and light, and can be easily communicated even when moving, and are very convenient. . The battery used in this mobile phone device is a package of rechargeable rechargeable batteries, and this packaged rechargeable battery has recently endured long-term continuous use and can be used for a long time. Are becoming mainstay.

A battery pack of a portable telephone device employing this lithium battery is inserted into a charger in a mounted state without being detached from the portable electronic device and charged, and the life thereof has been improved so that it can be used for several years. Therefore, it is rare that one or at most two battery packs are replaced with new battery packs by the end of the life cycle of the portable electronic device to which the battery pack is attached. However, when the battery pack is mounted on the main body of the portable electronic device, the structure of both uses a hook mechanism such as a claw that moves in parallel, and since this is a complicated structure, it becomes a bottleneck for measuring the price inexpensively. Has become.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to pay attention to the fact that the number of times that a battery pack is replaced with a new battery pack in the life cycle of a portable electronic device is extremely small. However, since the semi-fixed state with respect to the portable electronic device main body for a long period of time, it is necessary to eliminate the structurally expensive hook mechanism for attaching the battery pack to the portable electronic device main body and adopt a structure that can be easily attached and detached when necessary. Accordingly, the present invention provides a battery pack mounting structure that can be made inexpensive structurally without assembling labor, and can be made liquid-tight as required, thereby reducing the price as a whole.

[0005]

In order to solve the above-mentioned problems, a battery pack body containing at least a battery therein, an electronic device body to which power is supplied from the battery pack body, and an electronic device body A battery pack mounting structure, comprising: a magnet that attracts the battery pack body with a magnetic attraction force.

[0006]

By attaching the mounting surface of the battery pack body and the electronic device body with a magnet to a semi-fixed state so that they can be removed when necessary, a new battery pack can be replaced. This is a battery pack mounting structure that has simplified the structure and reduced the price.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, reference numeral 1 denotes a main body of an electronic device such as a portable communication device, for example, a portable telephone device, and this electronic device main body 1 is shown from the back. Electrodes 2 protrude from the electronic device body 1 at predetermined locations. The electronic device body 1 has 3
Although not shown, a battery pack body having a charging terminal electrically connected to the charger is attached. That is, a frame-shaped first magnet sheet 4 on the pack body side is attached to the battery pack body 3, while a frame-shaped second magnetic sheet 5 is attached to the electronic device body side, and both magnetic sheets are attached. The electronic device main body 1 and the battery pack main body 3 are attached by causing the magnetic heads 4 and 5 to be attracted by magnetic attraction. In this case, the first and second magnetic sheets 4 and 5 can be made liquid-tight by selecting a water-resistant sheet. If an elastic sheet is selected, the magnetically attracted surface can be attracted densely.

The battery pack body 3 has an electrode 6 which is electrically and elastically connected to the electrode 2. The first and second magnetic sheets 4 and 5 are provided on the electronic device main body 1 or the battery pack main body 3 while avoiding the electrodes 2 and 6. Therefore, since the first and second magnetic sheets 4 and 5 are water-resistant and liquid-tight as described above, after the electronic device main body 1 and the battery pack main body 3 are attached, water or the like is externally applied to the electrodes 2 and 6. Will not invade. Accordingly, the electrical connection between the electrodes 2 and 6 is not affected by moisture, and the structure can be relatively simple and the mounting can be realized.

Therefore, the magnetic sheets 4 and 5 are formed to the size of the mounting surface of the battery pack main body 3, and the first magnetic sheet 4 is embedded in the electronic apparatus main body 1 with its surface exposed.
On the other hand, the second magnetic sheet 5 is also buried in the battery pack main body 3 like the first magnetic sheet 4. In this state, when the battery pack body 3 is attached to the electronic apparatus body 1 by magnetically attracting the electrodes, the electrodes 2 and 6 are electrically and reliably electrically connected to complete the attachment.

When the battery pack is removed, the battery pack body 3 can be separated from the electronic device body 1 by raising the battery pack body 3 against the magnetic attraction of the first and second magnetic sheets 4 and 5. Therefore, the battery pack main body 3 and the electronic device main body 1 can be connected by simple means without forming a hook mechanism as in the related art, and can be realized at low cost.

[0012]

As described above, the present invention provides a battery pack main body containing at least a battery therein, an electronic device main body to which power is supplied from the battery pack main body, the electronic device main body, and the battery pack main body. A magnet mechanism that attracts the battery pack with a magnetic attraction force eliminates the structurally expensive hook mechanism that attaches the battery pack to the main body of the portable electronic device, and can be separated when necessary. The present invention can provide a battery pack mounting structure that is structurally inexpensive, has a liquid-tight structure, and is inexpensive as a whole.
