Abstract

PROBLEM TO BE SOLVED: To provide a battery pack attaching structure capable of decreasing cost as a whole by eliminating a structurally expensive hooking structure to attach the battery pack to a portable electronic apparatus and adopting a structure which can be detached when the need arises to make it easy to assemble and structurally inexpensive, since a battery pack is attached to a portable electric device of a long period. SOLUTION: This attaching structure has at least a battery pack main body 4 housing batteries, a recessed groove 6 formed on the side of a side opposing to the battery pack main body 4, an electronic apparatus main body 1 attached to the battery pack main body 4 and supplied with electric power by the battery pack main body 4, and a convex shelf 5 formed on the wall part of the side opposing to the electronic apparatus main body 1 and engaged with the recessed groove 6.

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 rechargeable battery packaged in a rechargeable battery. Recently, the mainstay of this packaged rechargeable battery is a rechargeable battery that can withstand continuous use for a long time. Have been doing.

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 battery life has been improved so that it can be used for several years. I have. Therefore, it is rare that a portable electronic device to which a battery pack is attached is replaced with a new battery pack by the end of its life cycle as a product, and it is considered that at most one battery pack or at most two battery packs are replaced. As described above, although the frequency of battery replacement is low, the structure for mounting the battery pack on the main body of the portable electronic device employs a very complicated and elaborate structure. That is, a hook structure such as a claw or the like that moves in parallel is adopted, and the price cannot be reduced because excessive quality is used although the frequency of use is low.

[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 battery pack is attached to the main body of the portable electronic device for a long time, it is necessary to eliminate the structurally expensive hook structure for attaching the battery pack to the main body of the portable electronic device and adopt a structure that can be easily removed when necessary. Accordingly, the present invention provides a battery pack mounting structure that can be structurally inexpensive without assembling labor and can be inexpensive as a whole.

[0005]

In order to solve the above-mentioned problems, a battery pack body accommodating at least a battery therein, a concave groove formed on a side of an opposite side of the battery pack body, An electronic device main body to which a pack main body is mounted and to which electric power is supplied from the battery pack main body, and a convex shelf formed on a wall portion of an opposite side of the electronic device main body and fitted with the concave groove, This is the mounting structure of the battery pack.

[0006]

The structure is simple by fitting the concave groove of the battery pack main body and the convex shelf of the electronic equipment main body, and can be removed when necessary, so that a new battery pack can be replaced. This is a battery pack mounting structure that has simplified the structure and reduced the price.

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

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 at predetermined locations in the electronic device main body 1 to form a concave portion 3 as a whole. Four battery pack bodies are attached to the electronic device body 1. That is, the overall dimensions of the battery pack main body 4 are selected so that the battery pack main body 4 can be incorporated into the concave portion 3 of the electronic device main body 1.

Therefore, in the assembled state, the thickness of the battery pack main body 4 substantially matches the depth of the electronic device main body 1 and becomes flat. Convex shelves 5 are formed on opposing walls inside the recess 3. A concave groove 6 formed on the side of the opposite side of the battery pack main body 4 fits into the convex shelf 5, and is fitted from above the concave portion 3 of the electronic device main body 1. FIG. 2 is a sectional view of the fitting portion. Of course, an electrode on the battery pack main body 4 side electrically connected to the electrode 2 is also formed.

The battery pack main body 4 is inserted into the recess 3 from above the electronic device main body 1. At this time, the opposing length of the protruding shelf 5 is shorter than the length of both sides of the battery pack main body 4 where the concave groove 6 is formed. For this reason, the battery pack body 4
And the concave groove 6 and the convex shelf 5 are fitted and fixed by fitting the battery pack body 4 into the concave portion 3.

When the battery pack main body 4 thus mounted is taken out of the concave portion 3, a minus screwdriver is inserted through the side opening of the electronic equipment main body 1, that is, the insertion opening 7 opened at the bottom side of the electronic equipment main body 1. When the battery pack main body 4 is raised, the convex shelf 5 is disengaged from the concave groove 6 and the battery pack main body 4 pops out. Thereby, the battery pack main body 4 can be removed from the concave portion 3 of the electronic device main body 1.

The above-mentioned convex shelves 5 are provided so as to face each other up and down. In this case, the concave grooves 6 on the side of the battery pack body 4 are naturally formed on the left and right sides.
Further, the insertion slot 7 is not limited to a flathead screwdriver, and may be anything as long as it is flat. In short, the insertion slot 7 only needs to be inserted from the insertion slot 7 to raise the battery pack body 4.
Further, it is a matter of course that the convex shelf 5 may be formed in the concave groove 6 and combined therewith instead of the concave groove 6.

[0013]

As described above, according to the present invention, a battery pack main body containing at least a battery therein, a concave groove formed on the side of the opposite side of the battery pack main body, and the battery pack main body are mounted. Since it is composed of an electronic device main body to which power is supplied from the battery pack main body and a convex shelf formed on a wall portion of the opposite side of the electronic device main body and fitted with the concave groove, it is structurally expensive. By eliminating the hook structure, it is possible to provide a battery pack mounting structure that is structurally inexpensive by eliminating the need for assembling by making it possible to remove it when necessary, and to reduce the price as a whole. is there.
