Description

【０００１】
【発明の属する技術分野】
この発明は、電子機器の電池カバーの取付け構造に係り、詳しくは、筐体本体に取り付けられた電池カバーのがたつきを抑制するようにした電子機器の電池カバーの取付け構造に関する。
【０００２】
【従来の技術】
例えば携帯電話、ＰＤＡ（ＰｅｒｓｏｎａｌＤｉｇｉｔａｌＡｓｓｉｓｔａｎｔｓ：個人向け携帯型情報通信機器）、携帯用ＧＰＳ（ＧｌｏｂａｌＰｏｓｉｔｉｏｎｉｎｇＳｙｓｔｅｍ）等の携帯用電子機器（（以下、単に電子機器とも称する）の電源として用いられている電池は、電子機器を構成している筐体本体に設けられた電池収納部に収納された状態で、筐体本体に取り付けられた電池カバーにより覆われるように構成されている。このような電子機器の電池カバーの取付け構造において、電子機器を安定に動作させるためには、筐体本体に対して電池カバーの取り付けを確実にして、電池収納部に収納した電池が動かないように保持する必要がある。もし、電池カバーの取り付けが不確実であると、電子機器の携帯中の振動等により電池カバーががたつくようになり、最悪の場合電池カバーが筐体本体から外れて電池が電池収納部から飛び出してしまうおそれがある。また、電池カバーが外れたことを気がつかない場合には、電池カバー自体を紛失してしまうこともある。
【０００３】
上述したような電池カバーが安易に外れることがないように構成した電子機器筐体（電子機器の電池カバーの取り付け構造）が開示されている（例えば、特許文献１参照。）。同電子機器の電池カバーの取付け構造は、図７に示すように、電池収納部１０３を有する筐体本体１０１と、この筐体本体１０１の一部に係合して筐体本体１０１に電池収納部１０３をカバーするように取り付けた状態を維持させるロック爪１０４を有する電池カバー１０２とを備えた構成において、筐体本体１０１にこの外面から底面まで貫通するように解除穴１０５が設けられるとともに、筐体本体１０１に電池カバー１０２のロック爪１０４と対向するようにストッパ１０６が設けられている。
【０００４】
このような構成によれば、筐体本体１０１の電池収納部１０３に電池（図示せず）を収納して電池カバー１０２を取り付ける（装着する）場合には、電池カバー１０２のロック爪１０４の先端部を開口部１０７の下側に押し込むことにより、ロック爪１０４を進入させて凹部１０８に位置した時点でロック爪４の先端部を凹部１０８に嵌合させる。一方、筐体本体１０１から電池カバー１０２を取り外す（離脱する）場合には、解除穴１０５からボールペンや鉛筆等を挿入してその先でロック爪１０４の先端部を押圧して撓ませることにより、ロックを解除させると同時に、筐体本体１０１から電池カバー１０２を取り外す。したがって、電池カバー１０２を筐体本体１０１に取り付けた状態では、電子機器の携帯中の振動等により電池カバー１０２が撓んだとしても、この撓みはストッパ１０６により規制されるので、電池カバー１０６が筐体本体１０１から外れることがなくなる。
【０００５】
また、電池カバーのロック不良の発生を防止するように構成した電池カバーのロック機構（電子機器の電池カバーの取付け構造）が開示されている（例えば、特許文献２参照。）。同電子機器の電池カバーの取付け構造は、図８及び図９に示すように、係合リブ２１２が形成された下側ケース２１１と、その係合リブ２０２と嵌合係止される係合爪２１４が形成された電池カバー２１３とを備えた構成において、係合リブ２１２は、外側垂直面２１２ａ−２１２ｂと頂部平面２１２ｂ−２１２ｃと、内側垂直面２１２ｃ−２１２ｄとから成り、頂部平面の内側角部２１２ｃがＲ面状に形成され、一方、係合爪２１４は凹溝２１４ａと先端傾斜辺２１４ｂとから形成され、凹溝２１４ａは電池カバー２１３の基部側垂直面２１４ｃ−２１４ｄと、底面２１４ｄ−２１４ｅと、先端側垂直面２１４ｅ−２１４ｆとから構成されている。
【０００６】
このような構成によれば、下側ケース２１１に電池カバー２１３を取り付ける場合には、電池カバー２１３が図９中矢印方向に押圧移動してその先端傾斜辺２１４ｂが係合リブ２１２の頂部２１２ｂに当接して下方にガイドされて撓みながら乗り上げ、さらに係合爪２１４の角部２１４ｃが係合リブ２１２の外側垂直面２１２ａ−２１２ｂに当接した状態で、係合爪２１４の凹溝２１４ａの開口端部２１４ｆは係合リブ２１２の頂部平面の内側角部２１２ｃに形成したＲ面に当たることなく、係合リブ２１２の基部２１２ｄまでなめらかに移動するので、下側ケース２１１の係合リブ２１２と電池カバー２１３の係合爪２１４が確実に嵌合係止されるようになる。したがって、下側ケース２１１の係合リブ２１２と電池カバー２１３の係合爪２１４とは、その初期係合する面にＲ面を設けて係合する部分を形成したので、初期の嵌合に際して互いの一端が当接せずになめらかな嵌合が行われ、嵌合後は互いにいずれかの部分で寸法差のない状態で嵌合係止されることになるため、確実なロックが行われ、電池カバー２１３が下側ケース２１３から外れることがなくなる。

【発明が解決しようとする課題】
しかしながら、特許文献１に開示されている電子機器の電池カバーの取付け構造では、電池カバーを筐体本体から取り外す際に道具を必要とするので、使い勝手が悪くなる、という問題がある。
すなわち、図７に示したような特許文献１記載の構成では、筐体本体１０１に設けたストッパ１０６の存在により電池カバー１０２が筐体本体１０１から外れるのを防止できるものの、電池カバー１０２を筐体本体１０１から取り外す際には、筐体本体１０１に設けた解除穴１０５からボールペンや鉛筆等の道具を用いて挿入してその先でロック爪１０４の先端部を押圧しなければならず、そのような道具がなければロックを解除できなくなるので使い勝手が悪くなる。
【０００９】
また、特許文献２に開示されている電子機器の電池カバーの取付け構造では、下側ケースの係合リブ及び電池カバーの係合爪の形成に高い寸法精度が要求されるので、構成部品である下側ケース及び電池カバーの量産性に欠ける、という問題がある。
すなわち、図８及び図９に示したような特許文献１記載の構成では、下側ケース２１１の係合リブ２１２と電池カバー２１３の係合爪２１４との初期係合する面にＲ面を設けるようにしたので、電池カバー２１３が下側ケース２１３から外れるのを防止できるものの、係合リブ２１２の幅寸法（頂部平面２１２ｂ−２１２ｃ間寸法）と係合爪２１４の凹溝２１４ａの幅寸法（底面２１４ｄ−２１４ｅ間寸法）とを略一致させる必要があるので高い寸法精度が必要となり、また係合リブ２１２の頂部平面の内側角部２１２ｃをＲ面状に加工しなけれならないため、下側ケース２１１及び電池カバー２１３を形成する際に成形用金型が高価になり、量産性に欠けるようになる。
【００１０】
この発明は、上述の事情に鑑みてなされたもので、電池カバーを取り外す際に道具を不要となして使い勝手を改善し、かつ構成部品の寸法精度を和らげて量産化を図ることができるようにした電子機器の電池カバーの取付け構造を提供することを目的としている。

【００１８】
【発明の実施の形態】
以下、図面を参照して、この発明の実施の形態について説明する。説明は、実施例を用いて具体的に行なう。
◇第１実施例
図１は、この発明の第１実施例である電子機器の電池カバーの取付け構造を示す斜視図、図２は図１のＡ−Ａ矢視断面図、図３及び図４は同電子機器の電池カバー取付け構造を構成するための電池カバーの装着方法を示す斜視図である。
この例の電子機器の電池カバーの取付け構造は、図１及び図２に示すように、電池収納部３が設けられた筐体本体１と、筐体本体１に電池収納部３をカバーするように取り付けられて筐体本体１に係合する係合爪４が設けられた電池カバー２とを備えた構成において、筐体本体１の内面の係合爪４に対向した位置にリブ（爪受け部）５が設けられるとともに、係合爪４とリブ５とを係合する際に係合爪４の矢印ａ方向への進入をガイドする傾斜面６Ａが、矢印方向に対して下り傾斜するように係合爪４の先端に設けられている。また、係合爪４の傾斜面６Ａの裏側位置にはコーナ部６Ｂが設けられ、傾斜面６Ａとコーナ部６Ｂとの間には平面６Ｃが設けられている。ここで、係合爪４の平面６Ｃは、係合爪４とリブ５との係合を確実にするために、リブ５の頂面６Ａよりも高い位置となるように形成されている。係合爪４はガイド部７を介して撓み可能に電池カバー２に設けられている。
【００１９】
筐体本体１及び電池カバー２は、ＰＥＴ（ポリエチレン・テレフタレート）、ポリプロピレン、塩化ビニール等の絶縁材料あるいはアルミニウムのような金属材料等の可撓性材料から構成されて、図１及び図２に示すように、筐体本体１の内部には電池収納部３を区画する座面８が、内部の側辺には凹部９が、また内部の中央のリブ５の下方には側縁部１０に連なる開口部１１がそれぞれ設けられている。また、リブ５は、頂面１２Ａ、第１の傾斜面１２Ｂ及び第２の傾斜面１２Ｃにより構成されている。
【００２０】
次に、図３及び図４をも参照して、この例の電子機器の電池カバーの取付け構造において、電池カバーを筐体本体に取り付ける方法及び電池カバーを筐体本体から取り外す方法について説明する。
まず、電池カバー２を筐体本体１に取り付ける場合には、図２に示した筐体本体１の電池収納部３に電池（図示せず）を収納した後、図３及び図４に示すように、電池カバー２を筐体本体１の凹部４に水平に配置してから、電池カバー２を凹部４に沿って矢印ａ方向にスライドさせて、係合爪４の先端を開口部１１に挿入して筐体本体１に係合させる。
【００２１】
より詳細に説明すると、矢印ａ方向にスライドされることにより電池カバー２の係合爪４が開口部１１に挿入されると、図２に示すように、係合爪４はその先端の傾斜面６Ａがリブ５の第２の傾斜面１２Ｃに当接して、下方にガイドされて破線で示すように撓みながら、リブ５の頂面１２Ａの下に回り込む。次に、係合爪４はさらに先に進んで、コーナ部６Ｂが頂面１２Ａの下を通過すると、コーナ部６Ｂがリブ５の第１の傾斜面１２Ｂに当接して傾斜面１２Ｂに沿って上昇して停止する。この係合爪４の停止する位置は、係合爪４の高さ位置により決定される。すなわち、前述したように、係合爪４の平面６Ｃをリブ５の頂面１２Ａよりも高い位置となるように形成することにより、係合爪４とリブ５との係合を確実にすることができる。これによって、電池カバー２は筐体本体１に取り付けられる。
【００２２】
上述したように電池カバー２が筐体本体１に取り付けられた状態では、電池カバー２の係合爪４のコーナ部６Ｂが筐体本体１のリブ５の第１の傾斜面１２Ｂに当接して係合されているとともに、電池カバー２の底面２Ａが座面８に当接するように構成されている。一方、電池カバー２のガイド部７が筐体本体１の側縁部１０に当接するように構成されている。
【００２３】
上述のような電子機器の電子機器の取付け構造によれば、図２に示すように、電池カバー２は、垂直方向（高さ方向）においては、その係合爪４がリブ５と当接して係合しているとともに、その底面２Ａが座面８と当接していることにより固定される。また、水平方向（左右方向）においては、係合爪４がリブ５と当接して係合しているとともに、側縁部１０と電池カバーガイド部７とが当接していることにより固定される。したがって、垂直方向及び水平方向において、電池カバー２は筐体本体１に確実に取り付けられるので、電池カバー２にがたつきは生じない。
【００２４】
次に、電池カバー２を筐体本体１から取り外す場合には、図１及び図２の状態において、手によって電池カバー２のガイド部７付近を矢印ｂ方向（垂直方向）に押圧することにより、係合爪４のコーナ部６Ｂとリブ５の第１の傾斜面１２Ｂとが当接していた係合状態が解除される。続いて、電池カバー２を手によって矢印ａ方向と反対方向に擦るようにして引くことにより、簡単に取り外すことができる。
上述したように、この例の電子機器の電池カバーの取付け構造によれば、電池カバー２を取り外す際に、従来のように道具を用いなくとも簡単に取り外すことができる。また、この例の電子機器の電池カバーの取付け構造によれば、係合爪４をリブ５に当接させて係合させるので、従来のように高い寸法精度は要求されないため、高価な成形用金型を用いなくとも、量産化を図ることができる。
【００２５】
このように、この例の電子機器の電池カバーの取付け構造によれば、電池収納部３が設けられた筐体本体１と、筐体本体１に電池収納部３をカバーするように取り付けられて筐体本体１に係合する係合爪４が設けられた電池カバー２とを備えた構成において、筐体本体１の内面の係合爪４に対向した位置にリブ５が設けられ、このリブ５と係合爪４とが当接して係合されているので、簡単な構成で取付け構造を実現することができる。
したがって、電池カバーを取り外す際に道具を不要となして使い勝手を改善し、かつ構成部品の寸法精度を和らげて量産化を図ることができる。
【００２６】
◇第２実施例
図５は、この発明の第２実施例である電子機器の電池カバーの取付け構造を示す断面図である。この例の電子機器の電池カバーの取付け構造の構成が、上述した第１実施例の構成と大きく異なるところは、凹部と凸部とを当接させて電池カバーを筐体本体に取り付けるようにした点である。
この例の電子機器の電池カバーの取付け構造は、図５に示すように、筐体本体１に爪受け部として動作する凹溝１３が設けられる一方、電池カバー２には円錐状の係合爪１４が設けられている。そして、円錐状の係合爪１４は、周囲面１４Ａが凹溝１３のコーナ部１３Ａと当接して係合している。
これ以外は、上述した第１実施例と略同様である。それゆえ、図５において、図２の構成部分と対応する各部には、同一の番号を付してその説明を省略する。
【００２７】
この例の電子機器の電池カバーの取付け構造によれば、円錐状の係合爪１４の周囲面１４Ａが凹溝１３のコーナ部１３Ａと当接して係合していることにより、係合爪１４の周囲面１４Ａが３６０°にわたって爪受け部としての凹溝１３のコーナ部１３Ａと当接して係合しているので、簡単な構成で強固に係合爪１４を凹溝１３に係合することができる。したがって、電池カバー２は筐体本体１に確実に取り付けられるので、電池カバー２にがたつきは生じない。
【００２８】
このように、この例によっても、第１実施例と略同様な効果を得ることができる。
【００２９】
◇第３実施例
図６は、この発明の第３実施例である電子機器の電池カバーの取付け構造を示す断面図である。この例の電子機器の電池カバーの取付け構造の構成が、上述した第２実施例の構成と大きく異なるところは、凹部と凸部とを当接させる構成において両者を点接触させて取り付けるようにした点である。
この例の電子機器の電池カバーの取付け構造は、図６に示すように、筐体本体１に爪受け部としての凹溝１５が設けられる一方、電池カバー２には円錐状の係合爪１６が設けられている。そして、円錐状の係合爪１６は、先端が凹溝１５の底部１５Ａと点接触により当接して係合している。ここで凹溝１５の開口角度は鈍角に設定され、係合爪１６の突出角度は、鋭角に設定されている。
これ以外は、上述した第２実施例と略同様である。それゆえ、図６において、図５の構成部分と対応する各部には、同一の番号を付してその説明を省略する。
【００３０】
この例の電子機器の電池カバーの取付け構造によれば、円錐状の係合爪１６の先端が凹溝１５の底部１５Ａと点接触により当接して係合しているので、より簡単な構成で係合爪１６を凹溝１５に係合することができる。特に、上述したように凹溝１５の開口角度を鈍角に設定し、係合爪１６の突出角度を鋭角に設定することにより、係合爪１６を凹溝１５に当接する際の位置決め操作を簡単にすることができる。したがって、電池カバー２は筐体本体１に確実に取り付けられるので、電池カバー２にがたつきは生じない。
【００３１】
このように、この例によっても、第２実施例と略同様な効果を得ることができる。
【００３２】
以上、この発明の実施例を図面により詳述してきたが、具体的な構成はこの実施例に限られるものではなく、この発明の要旨を逸脱しない範囲の設計の変更などがあってもこの発明に含まれる。例えば、実施例では携帯用電子機器に適用した例で説明したが、携帯用電子機器に限らずに、金融機関における現金自動預払機、交通機関における自動券売機等の電子機器、あるいは工業用の各種機械等の入力装置、さらには腕時計等のその他の装置にも適用することができる。
【００３３】
【発明の効果】
以上説明したように、この発明の電子機器の電池カバーの取付け構造によれば、電池収納部が設けられた筐体本体と、筐体本体に電池収納部をカバーするように取り付けられて筐体本体に係合する係合爪が設けられた電池カバーとを備えた構成において、筐体本体の内面の係合爪に対向した位置に爪受け部が設けられ、爪受け部と係合爪とが当接して係合されているので、簡単な構成で取付け構造を実現することができる。
したがって、電池カバーを取り外す際に道具を不要となして使い勝手を改善し、かつ構成部品の寸法精度を和らげて量産化を図ることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mounting structure of a battery cover of an electronic device, and more particularly, to a mounting structure of a battery cover of an electronic device in which rattling of a battery cover mounted on a housing body is suppressed.
[0002]
[Prior art]
For example, it is used as a power source for portable electronic devices (hereinafter, also simply referred to as electronic devices) such as a mobile phone, a PDA (Personal Digital Assistants), and a portable GPS (Global Positioning System). The battery is configured to be covered by a battery cover attached to the housing main body in a state of being stored in a battery housing portion provided in the housing main body constituting the electronic device. In order to ensure stable operation of electronic devices in the device battery cover mounting structure, it is necessary to securely attach the battery cover to the housing body and hold the battery housed in the battery housing so that it does not move If the installation of the battery cover is uncertain, In the worst case, the battery cover may come off from the housing body and the battery may jump out of the battery housing, and if the battery cover is not noticed, The cover itself may be lost.
[0003]
An electronic device housing (attachment structure of a battery cover of an electronic device) configured to prevent the above-mentioned battery cover from being easily detached is disclosed (for example, see Patent Document 1). As shown in FIG. 7, the mounting structure of the battery cover of the electronic device includes a housing body 101 having a battery housing portion 103, and a battery housing which is engaged with a part of the housing body 101 to be housed in the housing body 101. In a configuration including a battery cover 102 having a lock claw 104 for maintaining the attached state so as to cover the portion 103, a release hole 105 is provided in the housing body 101 so as to penetrate from the outer surface to the bottom surface, A stopper 106 is provided on the housing body 101 so as to face the lock claw 104 of the battery cover 102.
[0004]
According to such a configuration, when a battery (not shown) is stored in the battery storage portion 103 of the housing body 101 and the battery cover 102 is attached (attached), the tip of the lock claw 104 of the battery cover 102 By pushing the part below the opening 107, the lock claw 104 is advanced and the tip of the lock claw 4 is fitted into the recess 108 when the lock claw 104 is positioned in the recess 108. On the other hand, when removing (removing) the battery cover 102 from the housing body 101, a ballpoint pen, a pencil, or the like is inserted from the release hole 105, and the tip of the lock claw 104 is pressed and bent at the tip thereof. At the same time as the lock is released, the battery cover 102 is removed from the housing body 101. Therefore, in a state where the battery cover 102 is attached to the housing main body 101, even if the battery cover 102 bends due to vibration of the electronic device while being carried, the bending is regulated by the stopper 106. It does not come off the housing body 101.
[0005]
In addition, a battery cover lock mechanism (a structure for mounting a battery cover of an electronic device) configured to prevent occurrence of battery cover lock failure is disclosed (for example, see Patent Document 2). As shown in FIGS. 8 and 9, the mounting structure of the battery cover of the electronic device includes a lower case 211 on which an engagement rib 212 is formed, and an engagement claw that is engaged with and engaged with the engagement rib 202. In the configuration including the battery cover 213 on which the 214 is formed, the engagement rib 212 includes an outer vertical surface 212a-212b, a top plane 212b-212c, and an inner vertical plane 212c-212d, and an inner corner of the top plane. The portion 212c is formed in an R-plane shape, while the engaging claw 214 is formed by a concave groove 214a and a tip inclined side 214b, and the concave groove 214a is formed on a base vertical surface 214c-214d of the battery cover 213 and a bottom surface 214d- 214e and a front-side vertical surface 214e-214f.
[0006]
According to such a configuration, when the battery cover 213 is attached to the lower case 211, the battery cover 213 is pressed and moved in the direction of the arrow in FIG. When the corners 214c of the engaging claws 214 contact the outer vertical surfaces 212a-212b of the engaging ribs 212, the openings of the concave grooves 214a of the engaging claws 214 are brought into contact. The end portion 214f smoothly moves to the base portion 212d of the engagement rib 212 without hitting the R surface formed on the inner corner portion 212c of the top surface of the engagement rib 212, so that the engagement rib 212 of the lower case 211 and the battery The engagement claws 214 of the cover 213 are securely fitted and locked. Therefore, the engagement rib 212 of the lower case 211 and the engagement claw 214 of the battery cover 213 form an engagement portion by providing an R surface on the surface to be initially engaged. Smooth fitting is performed without one end of the abutting, and after fitting, it will be fitted and locked in a state where there is no dimensional difference in any part, so a secure lock is performed, The battery cover 213 does not come off the lower case 213.

[Problems to be solved by the invention]
However, the mounting structure of the battery cover of the electronic device disclosed in Patent Literature 1 requires a tool when removing the battery cover from the housing body, and thus has a problem that the usability is deteriorated.
That is, in the configuration described in Patent Document 1 as shown in FIG. 7, although the battery cover 102 can be prevented from being detached from the housing body 101 due to the presence of the stopper 106 provided on the housing body 101, the battery cover 102 When removing from the body main body 101, it is necessary to insert using a tool such as a ballpoint pen or a pencil through a release hole 105 provided in the housing main body 101 and press the tip of the lock claw 104 at the tip thereof. Without such a tool, it will not be possible to release the lock, so the usability will be poor.
