Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a combination structure of a battery pack which is attached to, for example, an electronic device main body and supplies power to the electronic device main body.

[0002]

2. Description of the Related Art In recent years, portable electronic devices such as portable telephones have been desired by users as a whole to be thin, lightweight, and compact, and these tendencies have been further strengthened. Such electronic devices employ a battery pack having a built-in rechargeable battery. This battery pack is made of a material such as plastic and is composed of an upper lid and a lower lid. Therefore, after the battery and / or the protection circuit are housed inside, the openings of the upper lid and the lower lid are bonded with an adhesive or the like.

Conventionally, the edges of the opening portions of the upper lid and the lower lid are flat, and an adhesive is applied to the flat portions and combined and bonded. For this reason, the adhesive overflows on the surface of the battery pack and impairs the appearance of the surface. In addition, the bonding is not sufficient because of the butt bonding with the flat surface. For this reason, a method of adopting an inlay fitting structure on the rim and applying an adhesive to it is used, but with a structure where the upper lid and the lower lid are only glued from the left and right at the rim part As a result, the battery pack itself is susceptible to impacts from the left and right, and often breaks, and the adhesive overflows to the outside, which is not sufficient for aesthetics.

[0004]

Accordingly, an object of the present invention is to provide a structure in which the opening edge portions of the upper lid and the lower lid are combined in an uneven structure, so that not only is the structure sufficiently reinforced against any external force, but also the adhesive is used. It does not leak to the outside of the surface and impairs the aesthetics.Moreover, the bonding area can be increased, so that the bonding can be made sufficient. An object of the present invention is to provide a battery pack lid assembly structure that does not cause a displacement in a reverse direction.

[0005]

Means for solving the problems of the present invention are first and second box-shaped first and second boxes each having a structure in which at least a battery is housed and which can be attached to an electronic apparatus body.
A battery pack main body, a convex portion formed on an edge of a second battery pack main body combined with the first battery pack main body, and a convex portion formed on the edge of the first battery pack main body combined with the convex portion. And a corrugated portion formed by combining desired portions where the convex portions and concave portions are combined into a waveform.

[0006]

The adhesive is applied to the convex or concave portion formed on the edge of the upper lid, and the concave or convex portion formed on the edge of the lower lid is combined with the adhesive and fixed. It can withstand the impact of external force sufficiently. In particular, it becomes strong against external forces from the left and right directions. In addition, by adopting the waveform, the upper lid and the lower lid can be bonded without causing a vertical displacement.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings, FIGS. 1 and 2. FIG. 1 shows a plastic battery pack body 1 combined with an upper lid 2 and a lower lid 3. FIG. FIG. 2 is a cross-sectional view taken along the line AA of FIG. As shown in FIG. 2, a protrusion 4 is formed at the opening edge of the battery pack main body 1 covered under the upper cover 2. On the other hand, a recess 5
To form That is, the shape and size are set so that the convex portion 4 and the concave portion 5 can be fitted with each other in a good condition. Therefore, the dimensions of the combination of the upper lid 2 and the lower lid 3 of the battery pack body 1 are determined so that no gap is opened.

The upper lid 2 and the lower lid 3 form a corrugated portion 6 composed of a convex portion 4 and a concave portion 5 combined in a waveform. The corrugated portion 6 is formed on one of the opposing side walls of the battery pack main body 1 and may not be formed on the entire longitudinal direction of the side wall, or may be formed on all opposing side walls. The formation of the corrugated portion 6 prevents the upper lid 2 and the lower lid 3 from being displaced in the direction of the arrow B, so that the upper lid 2 and the lower lid 3 can be reliably fixed at a prescribed position. This is particularly effective when the upper lid 2 and the lower lid 3 of the battery pack body 1 receive forces in directions opposite to each other.

Next, when the upper lid 2 and the lower lid 3 are combined and fixed, an adhesive H is applied to the concave portions 5 and the convex portions 4 are combined and inserted into the applied concave portions 5 to be bonded and fixed. As a result, the adhesive H does not protrude to the outside, so that the appearance is beautiful, the upper lid 2 and the lower lid 3 can be firmly fixed, and a battery pack main body that does not shift in the shifting direction can be configured.

[0010]

As described above, the present invention provides a first and second box-shaped battery pack main bodies each having at least a battery housed therein and configured to be attachable to an electronic apparatus main body. A convex portion formed on the edge of the second battery pack main body combined with the first battery pack main body; a concave portion formed on the edge of the first battery pack main body combined with the convex portion; And a corrugated portion formed by corrugating a desired portion to be combined with the concave portion, and at least a battery is housed therein, and the first portion of the box-shaped structure is configured to be attachable to the electronic device body. And a second battery pack main body, a convex portion formed on an edge of the second battery pack main body combined with the first battery pack main body, and an edge of the first battery pack main body combined with the convex portion. Recess formed in And a corrugated side wall portion in which the opposite side wall portion of the battery pack body in which the convex portion and the concave portion are combined is formed by corrugating the corrugated wall portion, so that the appearance can be beautifully secured and the force against displacement This is a battery pack lid assembly structure that can sufficiently withstand the above problems, and has a great effect such as structural reinforcement.
