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 battery pack which is attached to an electronic device such as a portable electronic device and has a function of supplying power.

[0002]

2. Description of the Related Art Recent electronic devices, such as portable video and digital cameras, are rapidly becoming popular because of their small size, light weight, smooth operation even during movement, and very high convenience. The batteries used in such electronic devices are packaged rechargeable secondary batteries. This type of packaged battery pack has been able to withstand continuous use for a long time because the type of batteries contained therein has been changed to lithium.

However, the handling of lithium batteries used in such battery packs is very strict with respect to other types of batteries. For example, temperature control, charging condition, impact, and the like must be sufficiently controlled. Therefore, it is an important requirement not only to take care not to drop the battery pack itself to give an impact, but also to prevent the case itself from being broken. Normally, the battery pack is made of plastic and has a box shape, so that it is considered that the battery pack is easily broken when an impact is given to a flat portion.

[0004] Therefore, it is desired to improve these corners into a structure that can withstand an impact. Also, battery packs are usually divided into S type and L type.For long-term use, L type with large capacity is used from the beginning, or S type which does not protrude relatively from electronic equipment is used first. We change to L type according to battery consumption. At the time of this replacement, when the battery pack is held and the battery pack is made of plastic, the battery pack is inadvertently slipped off from a finger unless it is firmly held.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the strength of the case itself of the battery pack body, prevent the battery pack body from slipping down even if it is held with a fingertip, and furthermore, a battery pack structure in which the direction can be confirmed with the fingertip. To provide.

[0006]

A battery pack containing at least one rechargeable battery therein, having a terminal capable of supplying power of the rechargeable battery to the electronic device body, and having a structure detachable from the electronic device body. In the battery pack structure of the main body, a first line formed of a plurality of linear shapes formed on a surface of the battery pack main body opposite to the surface attached to the electronic device main body.
And a second linear group formed of a plurality of linear shapes formed in a direction different from the linear direction of the first linear group and on the remaining surface on which the first linear group is formed. It consists of:

[0007]

In order to reinforce the battery pack main body against impact, a linear portion is formed on the flat portion of the battery pack main portion, and another portion of the linear portion is formed at a different position in the linear direction by approximately 90 degrees.
A linear shape is formed in the direction of the degree, so that when the finger is picked with a fingertip, the line is rubbed and the hand does not slip down. In addition, since the linear shape is arranged at an angle of about 90 degrees, the mounting direction can be recognized without being visually observed when the electronic device is mounted on an electronic device.

[0008]

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

FIG. 1 shows a battery pack body 1 attached to a portable electronic device such as a video tape recorder. The battery pack body 1 accommodates a lithium battery therein and can supply power to a video tape recorder (not shown). Are provided with electrode terminals. The battery pack body 1
Is box-shaped and made of a material such as a synthetic resin. The battery pack body 1 has an upper lid 2 and a lower lid 3 ultrasonically welded around.

Therefore, the battery pack main body 1 has a structure in which a battery and a protection circuit for managing the battery are housed inside. A first linear group 4 is formed on the upper surface of the battery pack main body 1, that is, on the side opposite to the side attached to the video tape recorder. The first linear group 4 is formed by making the plurality of linear groups 6 parallel to each other and forming them in about half of the area of the upper surface. Therefore, the surface becomes uneven and about half the area remains. In the remaining area, a second linear group 5 is formed for the first linear group 4.

The structure of the second linear group 5 is the same as that of the first linear group 4, but the direction of the plurality of linear lines 7 forming the second linear group 5 is the first linear group. It has a plane inclination of about 90 degrees with respect to the plurality of linears 6 of the group 4. Therefore, in this case, it can be seen at the fingertip that the first linear group 4 is parallel to the upper side of the battery pack main body 1. In addition, it can be seen from the fingertip that the second linear group 5 has the linear shape 6 parallel to the side of the battery pack body 1.

Therefore, even when the battery pack main body 1 is mounted on a video tape recorder in a dark place, for example, it is possible to determine the orientation of the battery pack main body 1 with respect to the video tape recorder, and it is difficult to mount the battery pack main body. Not something. Further, since the first linear group 4 and the second linear group 5 are composed of a plurality of 6, 7 linear shapes, they do not slide down even when pinched with a fingertip, and the direction of pinching with a fingertip is not limited. Angle of about 90 degrees as the first
, And a second linear group 5. FIG. 2 schematically shows the linear shapes 6 and 7 of the first and second linear groups 4 and 5.

In the above-mentioned embodiment, each line 6 of the first line group 4 and each line 7 of the second line group 5 are arranged parallel to the upper and lower sides and the side sides and at an angle of about 90 degrees to each other. However, the invention is not limited to this, and the linear shape 6 of the first linear group 4 may be configured as a diagonal line, and the linear shape 7 having an angle of about 90 degrees with the linear shape may be the linear shape of the second linear group. Of course. The linear shapes 6 and 7 of the first linear group 4 and the second linear group 5 do not have to be substantially 90 degrees, and the number of linear groups does not matter.

[0014]

As described above, the present invention has a structure in which at least one secondary battery is housed, a terminal capable of supplying the power of the secondary battery to the electronic device main body, and which can be attached to and detached from the electronic device main body. In the battery pack structure of the battery pack body described above, a first linear group consisting of a plurality of linear forms formed on a surface of the battery pack main body on the opposite side attached to the electronic device main body, and the first linear form A second linear group consisting of a plurality of linear groups formed in a direction different from the linear direction of the group and on the remaining surface on which the first linear group is formed. Therefore, it is possible to provide a battery pack structure that improves the strength of the case itself of the battery pack body, prevents the battery pack body from slipping down when held by a fingertip, and has a great effect such that the direction can be confirmed with the fingertip.

In order to reinforce the battery pack main body against impact, a filament is formed on a flat portion of the battery pack main body, and another portion of the linear portion is formed at another position with respect to the direction of the filament.
By forming a striated line in the degree direction, it is possible to prevent the striated object from sliding down from the hand when it is gripped with a fingertip. Therefore, it is possible to surely grasp without grasping the direction of grasping with the fingertip.
In addition, since the filaments are arranged at an angle of about 90 degrees, the mounting direction can be recognized without looking at the eyes when mounting the electronic apparatus.
