Description

【0001】
【発明の属する技術分野】
本発明は、携帯型電子機器のバッテリカバーの開閉機構に関する。
【0002】
【従来の技術】
携帯型の電子機器はバッテリにより駆動されており、装置本体にはそのバッテリを収納するための収納部が設けられている。バッテリ収納部に収納されたバッテリはバッテリカバーにより覆われており、このバッテリカバーは、バッテリの交換が簡単に行えるように開閉が簡単で、かつ収納してあるバッテリが外に飛び出したりしないような構造である必要がある。
【0003】
【発明が解決しようとする課題】
図5は従来のバッテリカバー41の開閉機構の説明図である。同図(A)は、バッテリカバー41を開いてバッテリ42をバッテリ収納部43から取り外すときの状態を示しており、同図(B)は、バッテリ42を収納部43に収納した状態で、バッテリカバー41の測部から見た断面図である。
【0004】
バッテリ42をバッテリ収納部43に収納した状態では、同図(B)に示すようにバッテリカバー41のつめ41aが装置本体44の凹部(図示せず)に引っかかり、バッテリカバー41はその状態でロックされている。バッテリ42を交換する場合には、バッテリカバー41のロックを外してバッテリカバー41を開いてバッテリ42を交換する。
【0005】
携帯型電子機器では、ユーザが装置を持ち運んで使用することから、装置本体に衝撃が加わることが考えられ、多少の衝撃では動作上支障のないことが望まれる。
【0006】
上述したような構造のバッテリカバー開閉機構を有する電子機器に、たとえば落下の衝撃が加わると、同図(B)に示すように落下の衝撃によりバッテリ42が飛び出す方向aと、バッテリカバー41を開く方向bとが一致するので、落下の衝撃が大きいとバッテリ42が外に飛び出そうとする力でバッテリカバー41のロックが外れ、バッテリ42が装置本体44から外に飛び出してしまうという問題点があった。
【0007】
本発明の課題は、衝撃が加わったときにもバッテリが装置本体から飛び出さないようにすることである。
【0008】
【課題を解決するための手段】
本発明は、携帯型電子機器のバッテリカバーの開閉機構であって、バッテリを収容するバッテリ収容部と、前記バッテリ収容部に収容されたバッテリを覆うバッテリカバーとからなり、前記バッテリ収容部は、中蓋と、前記バッテリ収容部の上面に固定された弾性部材と、前記バッテリカバーの挿入方向の手前側から奥側に向かって傾斜した傾斜面を有する第1の案内板を有し、前記バッテリカバーは、挿入方向の手前側から奥側に向かって傾斜した傾斜面を有する第2の案内板を有し、前記第1の案内板の傾斜面に沿って前記第2の案内板の傾斜面をスライドさせて前記バッテリカバーを挿入したときに、前記第1の案内板の傾斜面と前記第2の案内板の傾斜面が接触するにつれて、前記弾性部材と前記中蓋とが密着するように前記弾性部材がスライド方向に対して垂直方向に圧縮される構造である。
【0009】
本発明によれば、バッテリカバーの開閉方向がバッテリの取り出し方向と異なるので、落下等の衝撃が加わってバッテリに装置本体から飛び出す方向の力が働いても、バッテリカバーを開く方向にはその力は作用しないので、落下の衝撃によりバッテリが装置本体から飛び出すことが無くなる。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。携帯端末装置11の外観は図示していないが、装置本体11の表側にデータを入力する為の複数のキーからなるキー入力部と、入力されたデータを表示する液晶表示部とを備えており、裏面側にはバッテリ12を収納するバッテリ収納部15が設けられている。
【0011】
図1は、第1の実施の形態の携帯端末装置11のバッテリカバー開閉機構の説明図であり、同図(A)は、バッテリカバー13を装置本体11から外した状態で、装置本体11を裏面側から見た外観斜視図であり、同図(B)は、バッテリカバー13を装置本体11に取り付けた状態で、図1(A)のアーア方向から見た断面図であり、同図(C)は同じくイーイ方向から見た断面図である。
【0012】
バッテリカバー13は、図1(C)のイーイ断面に示すように、左右の端部13aがコの字状に曲げられており、その左右の端部13aが、装置本体11に収容されたバッテリ12の左右に設けられている案内板14と当接して、図1(A)の矢印c方向にスライドさせてバッテリカバー13を装置本体11に取り付けるようになっている。
【0013】
バッテリカバー13を矢印c方向にスライドさせて、バッテリカバー13の端面13bがバッテリ収納部15の端面15aに接触する位置まで押し込むと、バッテリ12はバッテリカバー13により覆われる。
【0014】
バッテリカバー13を装置本体11に完全に挿入した状態で、装置本体11に落下の衝撃が加わると、バッテリ12には、図1(B)の矢印Y方向の力が働き、バッテリ12は装置本体11の外に飛び出そうとする。一方、バッテリカバー13は、図1(B)の矢印X方向にはスライドするが、案内板14により矢印Y方向には動かないように規制されているので、落下の衝撃が加わってもバッテリカバー13は開かず、バッテリ12が装置本体11から外に飛び出すことはない。
【0015】
この第1の実施の形態によれば、バッテリカバー13を案内板14に沿ってスライドさせて装置本体11に取り付けるようにしたので、バッテリ12の取り出し方向とバッテリカバー13の開閉方向とが異なる。それにより、落下による衝撃が装置本体11に加わってもバッテリ12が装置本体11の外に飛び出すのを防止できる。
【0016】
次に、本発明の第2の実施の形態を図2を参照して説明する。図2(A)〜(C)は、中蓋21とパッキン25を用いてバッテリ収容部15を防滴構造にした第2の実施の形態の説明図であり、同図(A)は中蓋21を開いた状態での外観斜視図であり、同図(B)は図2(A)のアーア方向から見た断面図、同図(C)は、図2(B)のイ部の詳細図である。
【0017】
バッテリ収容部22は、直方体状で上部に開口を有し、その開口を中蓋21により覆うようになっている。バッテリ収容部22の両側面には、案内板23が設けられ、その案内板23に沿ってバッテリカバー24をスライドさせて中蓋21を覆うようになっている。
【0018】
バッテリカバー24を閉じるときには、先ずバッテリ収容部22にバッテリ12を挿入し、次に中蓋21を閉じる。さらに、バッテリカバー24を案内板23に沿ってスライドさせてバッテリカバー24の端面24aが装置本体11の端面に接触する位置まで押し込む。
【0019】
バッテリ収容部22の中蓋21と接触する外周上面部22aにはパッキン(弾性部材:ゴム、弾性プラスティック等)25が接着等により固定されている。このパッキン25と接触する中蓋21の先端には、図2(C)のイ部詳細図に示すようにパッキン25を圧縮するためのつめ21aが設けられている。
【0020】
従って、バッテリカバー24が案内板23に沿ってスライドされて装置本体11に取り付けられると、バッテリカバー24により中蓋21が押圧され、それにより中蓋21のつめ21aがパッキン25を圧縮して、中蓋21とバッテリ収容部22の外周上面部22aのパッキン25とが密着する。中蓋21とパッキン25とが密着すると、バッテリ収容部22の外部から内部に水滴が進入しないようになるのでバッテリ収容部22を防滴構造にすることができる。
【0021】
ところで、上述したような構造の開閉機構は、バッテリカバー24を装置本体11に挿入するときに、バッテリカバー24の内部上面で中蓋21を押さえ、パッキン25を圧縮するので、バッテリカバー24の先端部24aを装置本体11に挿入したときからパッキン25を圧縮するための力が必要となり、バッテリカバー24を奧に挿入するほど大きな力で挿入しなければならなくなる。
【0022】
この点を改良したのが、図3に示す第3の実施の形態である。この第3の実施の形態も、前述した第2の実施の形態と同様に、中蓋21と接触するバッテリ収容部22の外周上面部22aにパッキン25が接着等により固定されている。このパッキン25と接触する中蓋21の先端には、パッキン25を圧縮するためのつめ21aが設けられており、バッテリカバー34を装置本体11に取り付けたとき中蓋21とパッキン25によりバッテリ収容部22が密閉されるようにな構造となっている。
【0023】
バッテリ収容部22の両側面には案内板33が設けられている。この案内板33は、図3(B)のA−A断面図に示すように案内板33の上下方向の断面の幅dがバッテリカバー34が挿入される先端部33aから奥に向かって次第に広くなっている。つまり、案内板33の下面が挿入方向の手前側から奧側に向かって下がる方向に傾斜している。これに対応して、図3(B)のB−B断面に示すように、バッテリ収納部22の案内板33に沿ってスライドするバッテリカバー34の案内板35も上下方向の断面の幅eが挿入口の先端部35aから奥に向かって次第に広くなっている。つまり、案内板35の上面が挿入方向に向かって手前側(挿入口から見ると奧側)から奧側(挿入口)に向かって下がる方向に傾斜している。
【0024】
従ってバッテリカバー34をバッテリ収納部22の案内板33に沿って挿入するときに、最初に挿入されるバッテリカバー34の案内板35の先端部35aの断面の幅eは最小で、案内板33の先端部33aの幅dも最小であるので、バッテリカバー34の案内板35の先端部35aは案内板33の先端部33aと接触せず、バッテリカバー34を挿入するときにパッキン25を圧縮するための力はほとんど必要としない。
【0025】
そして、バッテリカバー34をさらに奥に押し込んでいってバッテリカバー34の案内板35の先端35aがバッテリ収納部22の案内板33と接触する位置まで進むと、バッテリカバー34の内面上部が中蓋31を、図3(B)の下方向に押圧する。バッテリカバー34により中蓋21が下方に押圧されると、中蓋21によりパッキン25が圧縮されてパッキン25と中蓋21とが密着する。
【0026】
その位置からさらにバッテリカバー34を奥に挿入すると、バッテリ収容部22の案内板33の断面の幅dが最大となる後端部33bと、バッテリカバー34の案内板35の断面の幅eが最小となる先端部35aとが当接し、案内板33の断面の幅dが最小となる先端部33aと、バッテリカバー34の案内板35の断面の幅eが最大となるろ部35bが当接する。
【0027】
すなわち、バッテリ収納部22の案内板33の下面を、バッテリカバー34の挿入方向の手前側から奧側に向かって下る傾斜面とし、その傾斜面に沿ってスライドさせるバッテリカバー24の案内板35の上面を、挿入方向の手前側から奧側に向かって下がる傾斜面とすることにより、バッテリカバー34をある程度奥に挿入するまで案内板33の傾斜面と案内板35の傾斜面とは接触せず、パッキン25を圧縮するための力は必要としないので、バッテリカバー34を装置本体11に挿入する初期の段階では大きな力を必要としない。
【0028】
そして、バッテリカバー34を案内板33に沿って奥に挿入するにつれて案内板33の傾斜面と案内板35の傾斜面とが接触するので、パッキン25を圧縮するための力が徐々に大きくなる。さらに、バッテリカバー34を挿入するにつれてパッキン25が次第に圧縮されるので、パッキン25を均一に圧縮することができ、パッキン25と中蓋21との密着性をより高めることができる。
【0029】
図4は、パッキン25と中蓋21との隙間が不均一な場合のパッキン25の圧縮状態を示す図である。
図4(A)に示すように中蓋21とパッキン25との間の隙間が、奧の部分21aで大きくなっている場合でも、上述したようにバッテリ収納部22の案内板33の断面形状を案内板33の先端部33aから奥に向かって断面の幅dが次第に広がる形状とし、それに対応してバッテリカバー34の案内板35の断面形状を挿入口から奥に向かって次第に広がる形状とすることにより、バッテリカバー34を挿入するに従って徐々にパッキン25を圧縮する力が大きくなり、案内板33の後端部33bでもパッキン25に充分に圧縮力が働く。これによりパッキン25が均一に圧縮されるので、図4(B)に示すようにパッキン25と中蓋21とが均一に密着する。
【0030】
上述した実施の形態は本発明を携帯端末装置に適用した場合であるが、それに限らずビデオカメラ、携帯型液晶テレビ、携帯ラジオ等の携帯型の電子機器に広く適用できる。また、バッテリカバーをスライドさせる方向は、図1のX方向に限らず、Y方向と直交する方向であればよい、
【0031】
【発明の効果】
本発明は、バッテリカバーの開閉方向をバッテリの取り出し方向と異ならせることで、装置本体に落下等による衝撃が加わったときに、バッテリカバーが外れてバッテリが装置本体の外に飛び出すことがなくなる。また、バッテリカバーをスライドさせて挿入するための案内板の接触面を、挿入方向の手前側から奧に向かって傾斜させることにより、バッテリカバーを装置本体に挿入するときに必要な力を少なくして、バッテリカバーをより取り付け易くできる。

[0003]
[Problems to be solved by the invention]
FIG. 5 is an explanatory view of a conventional opening / closing mechanism of the battery cover 41. FIG. 4A shows a state where the battery cover 41 is opened and the battery 42 is removed from the battery storage unit 43. FIG. 4B shows a state where the battery 42 is stored in the storage unit 43. FIG. 6 is a cross-sectional view of the cover 41 as viewed from the measuring unit.
[0004]
In the state in which the battery 42 is stored in the battery storage portion 43, the pawl 41a of the battery cover 41 is caught in a recess (not shown) of the apparatus main body 44 as shown in FIG. Has been. When the battery 42 is replaced, the battery cover 41 is unlocked, the battery cover 41 is opened, and the battery 42 is replaced.
[0005]
In a portable electronic device, since a user carries and uses the device, it is considered that an impact is applied to the device body, and it is desired that there is no problem in operation with a slight impact.
[0006]
For example, when a drop impact is applied to the electronic device having the battery cover opening / closing mechanism having the structure as described above, the direction a in which the battery 42 pops out due to the drop impact and the battery cover 41 are opened as shown in FIG. Since the direction b coincides, there is a problem that when the impact of the drop is large, the battery cover 41 is unlocked by the force that the battery 42 tries to jump out, and the battery 42 jumps out from the apparatus main body 44. It was.
[0007]
An object of the present invention is to prevent a battery from popping out of the apparatus main body even when an impact is applied.
[0008]

The elastic part There is a structure that is compressed in the direction perpendicular to the sliding direction.
[0009]
According to the present invention, since the opening / closing direction of the battery cover is different from the removal direction of the battery, even if an impact such as dropping is applied and a force in the direction of popping out of the main body of the battery is applied, the force in the direction of opening the battery cover Does not act, so the battery will not jump out of the main body due to the impact of dropping.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Although the external appearance of the mobile terminal device 11 is not shown, the mobile terminal device 11 includes a key input unit including a plurality of keys for inputting data on the front side of the device main body 11 and a liquid crystal display unit for displaying the input data. On the back side, a battery storage unit 15 for storing the battery 12 is provided.
[0011]
FIG. 1 is an explanatory diagram of a battery cover opening / closing mechanism of the mobile terminal device 11 according to the first embodiment. FIG. 1 (A) shows the device main body 11 with the battery cover 13 removed from the device main body 11. FIG. 4B is an external perspective view seen from the back side, and FIG. 4B is a cross-sectional view seen from the AA direction of FIG. 1A with the battery cover 13 attached to the apparatus main body 11. C) is a cross-sectional view seen from the same direction.
[0012]
As shown in FIG. 1C, the battery cover 13 has left and right end portions 13a bent in a U-shape, and the left and right end portions 13a are accommodated in the apparatus main body 11. The battery cover 13 is attached to the apparatus main body 11 by abutting against the guide plates 14 provided on the left and right sides of 12 and sliding in the direction of arrow c in FIG.
[0013]
When the battery cover 13 is slid in the direction of the arrow c and pushed into a position where the end surface 13 b of the battery cover 13 contacts the end surface 15 a of the battery housing 15, the battery 12 is covered with the battery cover 13.
[0014]
When a drop impact is applied to the apparatus main body 11 with the battery cover 13 completely inserted into the apparatus main body 11, a force in the direction of the arrow Y in FIG. Trying to jump out of 11. On the other hand, the battery cover 13 slides in the direction of the arrow X in FIG. 1B, but is regulated so as not to move in the direction of the arrow Y by the guide plate 14. Therefore, even if a drop impact is applied, the battery cover 13 13 is not opened, and the battery 12 does not jump out of the apparatus main body 11.
[0015]
According to the first embodiment, since the battery cover 13 is slid along the guide plate 14 and attached to the apparatus main body 11, the take-out direction of the battery 12 and the opening / closing direction of the battery cover 13 are different. Thereby, even if an impact due to dropping is applied to the apparatus main body 11, the battery 12 can be prevented from jumping out of the apparatus main body 11.
[0016]
Next, a second embodiment of the present invention will be described with reference to FIG. FIGS. 2A to 2C are explanatory views of a second embodiment in which the battery accommodating portion 15 has a drip-proof structure using the inner lid 21 and the packing 25, and FIG. 2B is a cross-sectional view as viewed from the AA direction in FIG. 2A, and FIG. 2C is a detail of the portion A in FIG. 2B. FIG.
[0017]
The battery housing part 22 has a rectangular parallelepiped shape and has an opening in the upper part, and the opening is covered with the inner lid 21. Guide plates 23 are provided on both side surfaces of the battery housing portion 22, and the battery cover 24 is slid along the guide plates 23 to cover the inner lid 21.
[0018]
When closing the battery cover 24, the battery 12 is first inserted into the battery housing portion 22, and then the inner lid 21 is closed. Further, the battery cover 24 is slid along the guide plate 23 and pushed into a position where the end surface 24 a of the battery cover 24 contacts the end surface of the apparatus main body 11.
[0019]
A packing (elastic member: rubber, elastic plastic or the like) 25 is fixed to the outer peripheral upper surface portion 22a in contact with the inner lid 21 of the battery housing portion 22 by adhesion or the like. At the tip of the inner lid 21 that comes into contact with the packing 25, a pawl 21a for compressing the packing 25 is provided as shown in FIG.
[0020]
Therefore, when the battery cover 24 is slid along the guide plate 23 and attached to the apparatus main body 11, the inner cover 21 is pressed by the battery cover 24, whereby the claw 21 a of the inner cover 21 compresses the packing 25, The inner lid 21 and the packing 25 on the outer peripheral upper surface portion 22a of the battery housing portion 22 are in close contact with each other. When the inner lid 21 and the packing 25 are in close contact with each other, water drops do not enter the inside of the battery housing portion 22 from the outside, so that the battery housing portion 22 can have a drip-proof structure.
[0021]
By the way, the opening / closing mechanism having the above-described structure presses the inner lid 21 on the inner upper surface of the battery cover 24 and compresses the packing 25 when the battery cover 24 is inserted into the apparatus main body 11. The force for compressing the packing 25 is required after the portion 24a is inserted into the apparatus main body 11, and the battery cover 24 must be inserted with a greater force as it is inserted into the bag.
[0022]
This point has been improved in the third embodiment shown in FIG. In the third embodiment as well, the packing 25 is fixed to the outer peripheral upper surface portion 22a of the battery housing portion 22 in contact with the inner lid 21 by adhesion or the like, as in the second embodiment described above. A claw 21 a for compressing the packing 25 is provided at the tip of the inner lid 21 that comes into contact with the packing 25. When the battery cover 34 is attached to the apparatus main body 11, the battery housing portion is held by the inner lid 21 and the packing 25. 22 is hermetically sealed.
[0023]
Guide plates 33 are provided on both side surfaces of the battery housing portion 22. As shown in the AA cross-sectional view of FIG. 3B, the guide plate 33 has a width d of the cross-section in the vertical direction of the guide plate 33 that gradually increases from the front end 33a into which the battery cover 34 is inserted toward the back. It has become. In other words, the lower surface of the guide plate 33 is inclined in a direction that descends from the near side in the insertion direction toward the heel side. Correspondingly, the guide plate 35 of the battery cover 34 that slides along the guide plate 33 of the battery housing 22 also has a width e of the cross section in the vertical direction, as shown in the BB cross section of FIG. It gradually becomes wider from the distal end portion 35a of the insertion opening toward the back. In other words, the upper surface of the guide plate 35 is inclined in the direction of descending from the near side (the heel side when viewed from the insertion port) toward the heel side (the insertion port) toward the insertion direction.
[0024]
Therefore, when the battery cover 34 is inserted along the guide plate 33 of the battery housing portion 22, the width e of the cross section of the front end portion 35 a of the guide plate 35 of the battery cover 34 to be inserted first is the smallest. Since the width d of the front end portion 33a is also the smallest, the front end portion 35a of the guide plate 35 of the battery cover 34 does not contact the front end portion 33a of the guide plate 33, and the packing 25 is compressed when the battery cover 34 is inserted. Little power is needed.
[0025]
Then, when the battery cover 34 is further pushed in and the tip 35a of the guide plate 35 of the battery cover 34 is advanced to a position where it contacts the guide plate 33 of the battery storage unit 22, the upper part of the inner surface of the battery cover 34 is the inner lid 31. Is pressed downward in FIG. When the inner lid 21 is pressed downward by the battery cover 34, the packing 25 is compressed by the inner lid 21 and the packing 25 and the inner lid 21 are brought into close contact with each other.
[0026]
When the battery cover 34 is further inserted from that position, the rear end portion 33b in which the width d of the cross section of the guide plate 33 of the battery housing portion 22 is maximum, and the width e of the cross section of the guide plate 35 of the battery cover 34 is minimum. The leading end portion 35a comes into contact with the leading end portion 33a where the width d of the cross section of the guide plate 33 is minimum, and the filter portion 35b where the width e of the cross section of the guide plate 35 of the battery cover 34 becomes maximum.
[0027]
That is, the lower surface of the guide plate 33 of the battery storage unit 22 is an inclined surface that descends from the near side in the insertion direction of the battery cover 34 toward the heel side, and the guide plate 35 of the battery cover 24 is slid along the inclined surface. By making the upper surface an inclined surface that descends from the near side in the insertion direction toward the heel side, the inclined surface of the guide plate 33 and the inclined surface of the guide plate 35 do not contact until the battery cover 34 is inserted to some extent. In addition, since a force for compressing the packing 25 is not required, a large force is not required at the initial stage of inserting the battery cover 34 into the apparatus main body 11.
[0028]
As the battery cover 34 is inserted deeper along the guide plate 33, the inclined surface of the guide plate 33 and the inclined surface of the guide plate 35 come into contact with each other, so that the force for compressing the packing 25 gradually increases. Further, since the packing 25 is gradually compressed as the battery cover 34 is inserted, the packing 25 can be uniformly compressed, and the adhesion between the packing 25 and the inner lid 21 can be further enhanced.
[0029]
FIG. 4 is a diagram illustrating a compressed state of the packing 25 when the gap between the packing 25 and the inner lid 21 is not uniform.
As shown in FIG. 4A, even when the gap between the inner lid 21 and the packing 25 is large at the flange portion 21a, the cross-sectional shape of the guide plate 33 of the battery storage portion 22 is changed as described above. The width d of the cross section gradually widens from the front end 33a of the guide plate 33 toward the back, and the cross-sectional shape of the guide plate 35 of the battery cover 34 correspondingly expands toward the back from the insertion port. As a result, the force for compressing the packing 25 gradually increases as the battery cover 34 is inserted, and a sufficient compressive force is applied to the packing 25 even at the rear end portion 33 b of the guide plate 33. As a result, the packing 25 is uniformly compressed, so that the packing 25 and the inner lid 21 are in close contact with each other as shown in FIG.
[0030]
The embodiment described above is a case where the present invention is applied to a portable terminal device, but is not limited to this, and can be widely applied to portable electronic devices such as a video camera, a portable liquid crystal television, and a portable radio. Further, the direction in which the battery cover is slid is not limited to the X direction in FIG.
[0031]
【The invention's effect】
According to the present invention, the opening / closing direction of the battery cover is different from the removing direction of the battery so that the battery cover is not removed and the battery does not jump out of the apparatus body when an impact due to dropping or the like is applied to the apparatus body. Also, by tilting the contact surface of the guide plate for sliding and inserting the battery cover from the near side in the insertion direction toward the heel, the force required when inserting the battery cover into the device body is reduced. Thus, the battery cover can be more easily attached.
