Description

【０００１】
【発明の属する技術分野】
本発明は、バッテリーパックが取り付けられる携帯電話機に関する。
【０００２】
【従来の技術】
従来の携帯電話機には、図７に示すものが知られている。これは、液晶パネル等の表示部(20)を設けた第１キャビネット(２)と、多数の操作釦(31)(31)を配列した第２キャビネット(３)をヒンジ(21)接続し、折り畳み可能に設けている(例えば、特許文献１参照)。
図８は、該携帯電話機を折り畳み、裏側から見た分解斜視図である。第２キャビネット(３)の裏側には、凹部(30)が設けられ、該凹部(30)内に略矩形状のバッテリパック(１)が嵌まる。第２キャビネット(３)上にて凹部(30)の側縁部には、凹部(30)に嵌まったバッテリパック(１)を係り止める爪片(４)がスライド可能に設けられ、該爪片(４)は、バッテリパック(１)の一端部に向かってバネ付勢されている。バッテリパック(１)の他端部には、突片(11)(11)が設けられており、該突片(11)(11)を凹部(30)の側壁に開設された穴(図示せず)に挿入し、該突片(11)(11)を中心としてバッテリパック(１)を下向きに回動させる。バッテリパック(１)の下端部に押されて爪片(４)は一旦バネ付勢に抗して、バッテリパック(１)から逃げる。バッテリパック(１)の下端部が爪片(４)を通過すれば、爪片(４)とバッテリパック(１)は係合し、バッテリパック(１)は第２キャビネット(３)に取り付けられる。即ち、爪片(４)はバッテリパック(１)のロック機構を構成する。

【発明が解決しようとする課題】
バッテリパック(１)は、凹部(30)の下面に設けられた端子(６)に接し、該端子(６)によって上向きに付勢される。爪片(４)がバッテリパック(１)の幅方向の中央である仮想線Ｌ上に位置すれば、バッテリパック(１)の何れか一方の側部が浮き上がることは防止される。
しかし、近年、携帯電話機の多機能化に伴って、第１キャビネット(２)上に種々のディスプレイ等を設けた結果、第２キャビネット(３)の裏側にスピーカ(５)を設けざるを得ない機種が出現した。爪片(４)が仮想線Ｌ上に位置すれば、スピーカ(５)を配置するスペースがないから、爪片(４)を仮想線Ｌから何れか側方、図８では左側に設ける必要が生じた。従って、バッテリパック(１)の右側が浮いてしまい、端子(６)とバッテリパック(１)との接触が不安定になる。
この点について、図９に示すように、仮想線Ｌの両側に夫々爪片(４)(４)を設け、第２キャビネット(３)上の仮想線Ｌ上のスペースを広く設け、該スペースにスピーカ(５)を配置する構成も考えられる。しかし、これでは爪片(４)(４)が２つあるので、部品点数が増加し、各爪片(４)(４)とバッテリパック(１)を係合させる必要があるから、操作も面倒である。
本発明の目的は、ロック機構が、バッテリパック(１)の幅方向の中央部から片寄せされて配置されても、バッテリパック(１)を浮かせないことにある。
【０００５】
【課題を解決する為の手段】
ロック機構は、バッテリパック(１)の一端部に嵌まる爪片(４)を具え、該爪片(４)には、バッテリパック(１)を下向きに押す突起(42)が設けられ、該突起(42)によりバッテリパック(１)は中央部Ｌに対して爪片(４)とは反対側の側部が下がる向きに回動する。
【０００６】
【作用及び効果】
爪片(４)が中央部Ｌに対してずれていると、端子(６)によってバッテリパック(１)は、中央部Ｌに対して爪片(４)とは反対側の側部が浮き上がらんとする。しかし、突起(42)によりバッテリパック(１)は中央部Ｌに対して爪片(４)とは反対側の側部が下がる向きに回動する。これにより、バッテリパック(１)の側部の浮き上がりは防止され、端子(６)とバッテリパック(１)との接触が安定する。
【０００７】
【発明の実施の形態】
以下、本発明の一例を図を用いて詳述する。本例にあっては、爪片(４)がバッテリパック(１)を、幅方向の中央部Ｌに対して爪片(４)とは反対側の側部が下がる向きに押すことを特徴とする。
図１は、携帯電話機の第２キャビネット(３)の裏側を示す分解斜視図である。従来と同様に、第２キャビネット(３)の裏面には、凹部(30)が形成され、該凹部(30)に矩形状のバッテリパック(１)が嵌まる。凹部(30)の底面には、バッテリパック(１)に電気的に接する端子(６)が出没可能に設けられ、該端子(６)はバッテリパック(１)を上向きに弾性付勢する。爪片(４)は少なくとも幅方向の中央部が、バッテリパック(１)の幅方向の中央部である仮想線Ｌに対して左側にずれて設けられ、第２キャビネット(３)上にて仮想線Ｌ上に、スピーカ(５)が設けられる。
第２キャビネット(３)の裏面には、浮かせ突片(32)、及びアンテナ(33)が設けられている。第２キャビネット(３)を図１とは上下逆にして机面に置いた場合、即ちスピーカ(５)を机面に対向させて置いた場合でも、浮かせ突片(32)及びアンテナ(33)によって、スピーカ(５)は机面から離れ、スピーカ(５)からの音を聞くことができる。
【０００８】
図２(a)は、図１をＡ方向から見た図であり、図２(b)は、図２(a)の左側面図である。バッテリパック(１)上にて、爪片(４)との対向箇所には凹み端面(10)が設けられ、爪片(４)は凹み端面(10)の周縁下端部を下向きに押す。
図３は、爪片(４)の斜視図であり、図４は図３をＢ−Ｂ線を含む面にて破断した断面図である。爪片(４)は、指で押される操作片(40)と該操作片(40)の下方に位置し凹み端面(10)の周縁下端部を押す押さえ片(41)とを具えている。押さえ片(41)の先端部は、操作片(40)の先端部よりもバッテリパック(１)側に位置し、操作片(40)はバッテリパック(１)には嵌まらない。
押さえ片(41)の上面隅部には、斜面(44)が形成され、バッテリパック(１)を凹部(30)に装着するときは、前記の如く、バッテリパック(１)の下端部が斜面(44)を押して、爪片(４)を一旦バッテリパック(１)から離れる向きに押す。バッテリパック(１)の下端部が斜面(44)を通過すると、爪片(４)は後記の押しバネ(34)により元の位置に復帰し、爪片(４)とバッテリパック(１)とが係合する。
操作片(40)の上面には、矢印(43)が付され、使用者は操作片(40)を矢印(43)の先端に向けて押すと、バッテリパック(１)と爪片(４)との係合が外れて、バッテリパック(１)を第２キャビネット(３)から取り出すことができる。
【０００９】
図４に示すように、爪片(４)は第２キャビネット(３)内に設けられた押しバネ(34)によってバッテリパック(１)に向けて付勢され、押さえ片(41)が凹み端面(10)に嵌まる。
図５は、図３をＣ方向から見た断面図である。押さえ片(41)の下面右端部には、突起(42)が設けられ、該突起(42)が凹み端面(10)の周縁下端部を下向きに押す。図５に示すように、バッテリパック(１)は押さえ片(41)の左端部と凹み端面(10)の周縁部との接点Ｄを中心として、時計方向に回動し、中央部Ｌに対して右側の側部が下降する。
爪片(４)は幅方向の中央部が、バッテリパック(１)の中央部Ｌに対して左側に片寄せされているから、バッテリパック(１)は端子(６)の付勢力によって右側の側部が浮き上がらんとする。しかし、突起(42)によってバッテリパック(１)は右側の側部が下降するから、バッテリパック(１)の右側の側部が浮き上がることは防止される。これにより、爪片(４)を中央部Ｌからずれた位置に配備しても、端子(６)とバッテリパック(１)の接触は安定する。爪片(４)は、１つで済むから、部品点数も増加しないし、取付け作業工程も増加しない。更に、爪片(４)のワンタッチ操作で、バッテリパック(１)を着脱できるので、操作性がよい。
【００１０】
本例にあっては、突起(42)によりバッテリパック(１)は中央部Ｌに対して爪片(４)とは反対側の側部が下がる向きに回動する。従って、爪片(４)が中央部Ｌに対して右側に設けられているときは、突起(42)を押さえ片(41)の下面左端部に設ければよい。
また、第２キャビネット(３)上にて、バッテリパック(１)の幅方向の中央部Ｌ上に配備される部品として、スピーカ(５)を例示したが、これに限定されない。例えば、カメラ素子、振動報知用バイブレータ、ＬＣＤでもよい。
更に、突起(42)は図３に一点鎖線で示すように、係合すべき凹み端面(10)に向かって突出し、凹み端面(10)との係り代を大きく設けてもよい。突起(42)と凹み端面(10)の周縁部との係り代が大きくなれば、バッテリパック(１)はより安定して側部が下向きに下がる。
また、図６に示すように、バッテリパック(１)の凹み端面(10)の周縁下端部に突起(42)を設け、爪片(４)の押さえ片(41)の下面にて、突起(42)を押してもよい。これによっても、バッテリパック(１)は時計方向に回動し、中央部Ｌに対して右側の側部が下降する。

[0004]
[Problems to be solved by the invention]
The battery pack (1) contacts a terminal (6) provided on the lower surface of the recess (30) and is urged upward by the terminal (6). If the claw piece (4) is positioned on the virtual line L that is the center in the width direction of the battery pack (1), it is possible to prevent any one side of the battery pack (1) from floating.
However, in recent years, with the increase in the number of functions of mobile phones, as a result of providing various displays and the like on the first cabinet (2), a speaker (5) has to be provided on the back side of the second cabinet (3). A model appeared. If the claw piece (4) is positioned on the imaginary line L, there is no space for placing the speaker (5), so the claw piece (4) must be provided on either side of the imaginary line L, on the left side in FIG. occured. Accordingly, the right side of the battery pack (1) floats, and the contact between the terminal (6) and the battery pack (1) becomes unstable.
In this regard, as shown in FIG. 9, claw pieces (4) and (4) are provided on both sides of the virtual line L, and a space on the virtual line L on the second cabinet (3) is provided wide. A configuration in which the speaker (5) is arranged is also conceivable. However, since there are two claw pieces (4) and (4) in this case, the number of parts increases, and it is necessary to engage each claw piece (4) and (4) with the battery pack (1). It is troublesome.
An object of the present invention is to prevent the battery pack (1) from being lifted even if the lock mechanism is arranged so as to be offset from the center in the width direction of the battery pack (1).
[0005]
[Means for solving the problems]
The locking mechanism includes a claw piece (4) that fits into one end of the battery pack (1), and the claw piece (4) is provided with a protrusion (42) that pushes the battery pack (1) downward. The protrusion (42) causes the battery pack (1) to rotate with respect to the central portion L such that the side opposite to the claw piece (4) is lowered.
[0006]
[Action and effect]
When the claw piece (4) is displaced with respect to the center portion L, the terminal (6) causes the battery pack (1) to lift away from the side opposite to the claw piece (4) with respect to the center portion L. And However, the protrusion (42) causes the battery pack (1) to rotate in such a direction that the side portion opposite to the claw piece (4) is lowered with respect to the central portion L. Thereby, the side part of the battery pack (1) is prevented from being lifted, and the contact between the terminal (6) and the battery pack (1) is stabilized.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of the present invention will be described in detail with reference to the drawings. In this example, the claw piece (4) pushes the battery pack (1) in such a direction that the side opposite to the claw piece (4) is lowered with respect to the central portion L in the width direction. To do.

[0008]
2A is a view of FIG. 1 viewed from the direction A, and FIG. 2B is a left side view of FIG. On the battery pack (1), a recessed end surface (10) is provided at a position facing the claw piece (4), and the claw piece (4) pushes the lower end of the peripheral edge of the recessed end surface (10) downward.
FIG. 3 is a perspective view of the claw piece (4), and FIG. 4 is a cross-sectional view of FIG. 3 taken along the plane including the line BB. The claw piece (4) includes an operation piece (40) to be pressed by a finger and a pressing piece (41) which is located below the operation piece (40) and presses the lower end of the peripheral edge of the recessed end surface (10). The tip of the holding piece (41) is positioned closer to the battery pack (1) than the tip of the operation piece (40), and the operation piece (40) does not fit into the battery pack (1).
A slope (44) is formed at the upper surface corner of the holding piece (41). When the battery pack (1) is mounted in the recess (30), the lower end of the battery pack (1) is inclined as described above. (44) is pressed, and the claw piece (4) is once pushed away from the battery pack (1). When the lower end of the battery pack (1) passes through the inclined surface (44), the claw piece (4) is returned to its original position by a later-described pressing spring (34), and the claw piece (4), the battery pack (1), Engage.
An arrow (43) is attached to the upper surface of the operation piece (40). When the user pushes the operation piece (40) toward the tip of the arrow (43), the battery pack (1) and the claw piece (4) are provided. And the battery pack (1) can be taken out from the second cabinet (3).
[0009]
As shown in FIG. 4, the claw piece (4) is urged toward the battery pack (1) by a pressing spring (34) provided in the second cabinet (3), and the holding piece (41) is a concave end surface. Fits in (10).
FIG. 5 is a cross-sectional view of FIG. 3 viewed from the C direction. A protrusion (42) is provided at the right end of the lower surface of the pressing piece (41), and the protrusion (42) pushes the lower end of the peripheral edge of the recessed end surface (10) downward. As shown in FIG. 5, the battery pack (1) rotates clockwise around the contact D between the left end portion of the holding piece (41) and the peripheral edge portion of the recessed end surface (10). The right side is lowered.
Since the claw piece (4) is centered in the width direction on the left side with respect to the center part L of the battery pack (1), the battery pack (1) is moved to the right side by the urging force of the terminal (6). The side part is lifted up. However, since the right side of the battery pack (1) is lowered by the protrusion (42), the right side of the battery pack (1) is prevented from being lifted. Thereby, even if it arrange | positions in the position which shifted | deviated the nail | claw piece (4) from the center part L, the contact of a terminal (6) and a battery pack (1) is stabilized.
