Description
本発明は、筐体への電池の収納構造を改良した電子機器に関する。 The present invention relates to an electronic apparatus having an improved battery storage structure in a housing.
携帯電話機や携帯型無線機等の各種の電子機器においては、筐体内に電池を収納して、電池より供給される電力によって電子機器が動作するようになっている。電池が水に濡れると故障の原因となることから、筐体内で電池を収納する電池収納部には防水構造を採用して電池収納部への水の浸入を防ぐことが必要である。 In various electronic devices such as a mobile phone and a portable wireless device, a battery is housed in a casing, and the electronic device is operated by electric power supplied from the battery. When the battery gets wet, it may cause a failure. Therefore, it is necessary to adopt a waterproof structure for the battery storage part that stores the battery in the housing to prevent water from entering the battery storage part.
また、電池に大きな衝撃が加わると故障の原因となることから、電池収納部には防水構造に加えて衝撃吸収構造を設けて、電池に加わる衝撃を吸収させることが必要である。 In addition, since a large impact on the battery may cause a failure, it is necessary to provide a shock absorbing structure in addition to the waterproof structure in the battery housing portion to absorb the impact applied to the battery.
一般的に、防水構造による防水効果や衝撃吸収構造による衝撃吸収効果を高めようとすると、部品点数が多くなったり、電池収納部が大きくなったりして、電子機器の小型化の妨げとなる。よって、部品点数を極力少なくし、電池収納部を極力小さくしつつ、電池に対する十分な防水効果と衝撃吸収効果を得ることができる電子機器が求められる。 In general, if the waterproof effect by the waterproof structure and the impact absorption effect by the shock absorbing structure are to be enhanced, the number of parts increases and the battery housing portion becomes large, which hinders downsizing of the electronic device. Therefore, there is a demand for an electronic device that can obtain a sufficient waterproof effect and shock absorption effect on the battery while minimizing the number of components and the battery housing portion as much as possible.
本発明はこのような要望に対応するため、部品点数を極力少なくし、電池収納部を極力小さくしつつ、電池に対する十分な防水効果と衝撃吸収効果を得ることができる電子機器を提供することを目的とする。 In order to meet such a demand, the present invention provides an electronic device that can obtain a sufficient waterproof effect and shock absorbing effect on a battery while minimizing the number of components and making the battery housing portion as small as possible. Objective.

A casing having a battery housing portion to be mounted, a mounting recess for mounting the battery, and a packing that covers the opening by holding the battery in contact with each surface of the battery mounted in the mounting recess And a lid attached to the opening covered by the packing of the housing.
本発明の電子機器によれば、部品点数を極力少なくし、電池収納部を極力小さくしつつ、電池に対する十分な防水効果と衝撃吸収効果を得ることができる。 According to the electronic device of the present invention, it is possible to obtain a sufficient waterproof effect and shock absorption effect for the battery while minimizing the number of components and making the battery housing portion as small as possible.
以下、一実施形態の電子機器について、添付図面を参照して説明する。以下詳述する一実施形態の電子機器は、携帯型無線機を例とする。電子機器は無線機に限定されず、筐体内に電池を収納して、電池より供給される電力によって動作する任意の電子機器であればよい。 Hereinafter, an electronic apparatus according to an embodiment will be described with reference to the accompanying drawings. An electronic device according to an embodiment described in detail below is a portable radio device as an example. The electronic device is not limited to a wireless device, and may be any electronic device that stores a battery in a housing and operates with electric power supplied from the battery.
図１に示す分解斜視図を用いて、一実施形態の電子機器の概略的な構成について説明する。図１において、筐体１０は、面１１〜１６によって概略直方体状に形成されている。筐体１０は、プラスチック樹脂によって形成されている。 A schematic configuration of an electronic apparatus according to an embodiment will be described with reference to an exploded perspective view illustrated in FIG. In FIG. 1, the housing | casing 10 is formed in the substantially rectangular parallelepiped shape by the surfaces 11-16. The housing 10 is made of plastic resin.
図１の上側である面１２には、略矩形状の開口１２ａが形成されている。開口１２ａが形成されている面１２は電子機器の裏面側であり、面１１を正面１１、面１２を裏面１２、面１３を上面１３、面１４を下面１４、面１５，１６をそれぞれ側面１５，１６と称することとする。 A substantially rectangular opening 12a is formed in the upper surface 12 of FIG. The surface 12 on which the opening 12a is formed is the back surface side of the electronic device. The surface 11 is the front surface 11, the surface 12 is the back surface 12, the surface 13 is the upper surface 13, the surface 14 is the lower surface 14, and the surfaces 15 and 16 are the side surfaces 15. , 16.
裏面１２には、開口１２ａを取り囲むように、裏面１２より上方に突出したリブ１２ｂが形成されている。ここでの上方とは、筐体１０に取り付ける後述する裏蓋６０の方向である。裏面１２の４つの角部には、ねじ孔１７ａ〜１７ｄが形成されている。上面１３の側面１６側の端部には、アンテナ１８が装着されている。 On the back surface 12, ribs 12b protruding upward from the back surface 12 are formed so as to surround the opening 12a. Here, the upper direction is the direction of a back cover 60 to be described later attached to the housing 10. Screw holes 17 a to 17 d are formed at four corners of the back surface 12. An antenna 18 is attached to an end of the upper surface 13 on the side surface 16 side.
正面１１の裏面である筐体１０の底面１０Ｂ上には、底面１０Ｂより突出した図示していない複数のリブが形成されている。回路基板２０は開口１２ａより筐体１０の内部へと挿入され、底面１０Ｂより突出して形成されたリブ上に載置される。よって、回路基板２０は、底面１０Ｂから若干の距離だけ離間した状態で筐体１０内に収納される。 A plurality of ribs (not shown) projecting from the bottom surface 10B are formed on the bottom surface 10B of the housing 10 which is the back surface of the front surface 11. The circuit board 20 is inserted into the housing 10 through the opening 12a and placed on a rib formed so as to protrude from the bottom surface 10B. Therefore, the circuit board 20 is accommodated in the housing 10 in a state of being separated from the bottom surface 10B by a slight distance.
正面１１を構成する板には、携帯型無線機として必要な各種の開口部が形成されているが、図１では簡略化のため、開口部の図示を省略している。 Various openings necessary for the portable radio device are formed on the plate constituting the front surface 11, but the illustration of the openings is omitted in FIG. 1 for simplification.
回路基板２０の１つの角部の近傍には、電力供給用のコネクタ２１が接続されている。回路基板２０には、集積回路２２や各種の回路部品２３等が実装されている。 A power supply connector 21 is connected in the vicinity of one corner of the circuit board 20. An integrated circuit 22 and various circuit components 23 are mounted on the circuit board 20.
筐体１０内に収納された回路基板２０上には、隔壁板３０が被せられる。隔壁板３０は一例としてアルミニウム等の金属板により形成されている。隔壁板３０は筐体１０内の空間を仕切る役割を果たすと共に、後述するように熱を吸収する吸熱体として作用する。従って、隔壁板３０は金属であることが好ましく、アルミニウムは特に好ましい。隔壁板３０は、複数の開口部３１と、段差部３２とを有する。 A partition plate 30 is placed on the circuit board 20 accommodated in the housing 10. The partition plate 30 is formed of a metal plate such as aluminum as an example. The partition plate 30 functions to partition the space in the housing 10 and also acts as a heat absorber that absorbs heat as will be described later. Therefore, the partition plate 30 is preferably a metal, and aluminum is particularly preferable. The partition plate 30 has a plurality of openings 31 and step portions 32.
図２は、筐体１０内に回路基板２０を収納し、回路基板２０上に隔壁板３０を被せた状態を示している。 FIG. 2 shows a state in which the circuit board 20 is housed in the housing 10 and the partition plate 30 is put on the circuit board 20.
図３は、図２のＡ−Ａ断面図である。図３では簡略化のため、隔壁板３０の回路基板２０側の面の全てが回路基板２０に接しているように図示しているが、隔壁板３０は、回路基板２０の少なくとも一部または回路基板２０上に実装された少なくとも一部の部品（集積回路２２または回路部品２３等）に接していればよい。回路基板２０または部品が隔壁板３０と接することにより、隔壁板３０は回路基板２０や部品が発生させる熱を吸収する吸熱効果を奏する。 FIG. 3 is a cross-sectional view taken along the line AA of FIG. In FIG. 3, for simplicity, the entire surface of the partition plate 30 on the side of the circuit board 20 is shown in contact with the circuit substrate 20, but the partition plate 30 is at least part of the circuit substrate 20 or the circuit. It suffices to be in contact with at least a part of components (such as the integrated circuit 22 or the circuit component 23) mounted on the substrate 20. When the circuit board 20 or the component is in contact with the partition plate 30, the partition plate 30 has an endothermic effect of absorbing heat generated by the circuit substrate 20 or the component.
図３に示すように、筐体１０内の空間は、隔壁板３０によって、隔壁板３０より正面１１側であり、回路基板２０を収納する回路基板収納部10h20と、隔壁板３０より裏面１２側であり、後述する電池５０等を収納する電池収納部10h50とに分割される。回路基板収納部10h20は筐体１０の底面１０Ｂ側に位置し、電池収納部10h50は回路基板収納部10h20の上部に位置している。 As shown in FIG. 3, the space in the housing 10 is on the front 11 side from the partition plate 30 by the partition plate 30, the circuit board storage portion 10 h 20 that stores the circuit board 20, and the back surface 12 side from the partition plate 30. And is divided into a battery storage portion 10h50 for storing a battery 50 and the like to be described later. The circuit board housing portion 10h20 is located on the bottom surface 10B side of the housing 10, and the battery housing portion 10h50 is located above the circuit board housing portion 10h20.
図１に戻り、板状の電池５０は、本実施形態においては、例えばリチウムイオン電池のような二次電池である。電池５０は二次電池に限定されず、一次電池であってもよい。電池５０の種類及び形状は任意である。但し、電池５０の形状としては、６面を有する略直方体であることが好ましい。本実施形態では、電池５０は、図１における下側の底面と、上側の上面と、底面と上面とで挟まれた４つの側面を有する。 Returning to FIG. 1, the plate-like battery 50 is a secondary battery such as a lithium ion battery in the present embodiment. The battery 50 is not limited to a secondary battery, and may be a primary battery. The type and shape of the battery 50 are arbitrary. However, the shape of the battery 50 is preferably a substantially rectangular parallelepiped having six surfaces. In the present embodiment, the battery 50 has four side surfaces sandwiched between the lower bottom surface, the upper upper surface, and the bottom surface and the upper surface in FIG.
電池５０より引き出されたケーブル５２はコネクタ５１に接続されている。コネクタ５１はコネクタ２１に接続され、電池５０が発生する電力が回路基板２０へと供給されて電子機器が動作する。 A cable 52 drawn from the battery 50 is connected to the connector 51. The connector 51 is connected to the connector 21, and the electric power generated by the battery 50 is supplied to the circuit board 20 to operate the electronic device.
電池５０は、絶縁体により形成されたパッキング４０の装着凹部４１に装着される。装着凹部４１に装着された電池５０は、電池収納部10h50に収納される。パッキング４０は、所定の弾性材料により形成される。弾性材料としては、一例としてシリコーンゴムが好適である。パッキング４０の具体的な形状については後述する。 The battery 50 is mounted in the mounting recess 41 of the packing 40 formed of an insulator. The battery 50 mounted in the mounting recess 41 is stored in the battery storage unit 10h50. The packing 40 is formed of a predetermined elastic material. As an elastic material, silicone rubber is suitable as an example. The specific shape of the packing 40 will be described later.
図２，図３の状態に対して、装着凹部４１に装着されることによってパッキング４０と一体化された電池５０が電池収納部10h50に収納されると、筐体１０の裏面１２には裏蓋６０が被せられる。図１に示すように、裏蓋６０を、ねじ７０ａ〜７０ｄによってねじ孔１７ａ〜１７ｄに締め付けることによって、図１における筐体１０から裏蓋６０までの全てが一体化されて、本実施形態の電子機器が構成される。 2 and 3, when the battery 50 integrated with the packing 40 by being mounted in the mounting recess 41 is stored in the battery storage unit 10h50, the back surface 12 of the housing 10 has a back cover. 60 is applied. As shown in FIG. 1, by tightening the back cover 60 to the screw holes 17a to 17d with screws 70a to 70d, all of the case 10 to the back cover 60 in FIG. Electronic equipment is configured.
本実施形態においては、筐体１０の開口１２ａが形成されている面１２を電子機器の裏面側としているので裏蓋６０と称しているが、開口１２ａが形成されている面１２を電子機器の正面側としてもよい。この場合、裏蓋６０は正面側の蓋となる。 In the present embodiment, the surface 12 on which the opening 12a of the housing 10 is formed is referred to as the back cover 60 because it is the back side of the electronic device, but the surface 12 on which the opening 12a is formed is referred to as the electronic device. It may be the front side. In this case, the back cover 60 serves as a front cover.
図４，図５を用いて、パッキング４０の具体的な形状について説明する。パッキング４０の装着凹部４１は、底面４０Ｂと、底面４０Ｂに対して直交する４つの壁４３〜４６とによって、略矩形状に形成されている。装着凹部４１に電池５０が装着されると、電池５０の底面と底面４０Ｂとが接触し、電池５０の４つの側面は４つの壁４３〜４６それぞれと接触する。電池５０の上面には、後述する押さえ部４７，４８が接触する。 A specific shape of the packing 40 will be described with reference to FIGS. The mounting recess 41 of the packing 40 is formed in a substantially rectangular shape by a bottom surface 40B and four walls 43 to 46 orthogonal to the bottom surface 40B. When the battery 50 is mounted in the mounting recess 41, the bottom surface of the battery 50 and the bottom surface 40B are in contact with each other, and the four side surfaces of the battery 50 are in contact with the four walls 43 to 46, respectively. On the upper surface of the battery 50, pressers 47 and 48 described later are in contact.
このように、パッキング４０は電池５０の６面全てに接触して、電池５０を保護する。パッキング４０は、電池５０の６面全てで衝撃吸収効果を奏する。 In this way, the packing 40 contacts all six surfaces of the battery 50 to protect the battery 50. The packing 40 has an impact absorbing effect on all six surfaces of the battery 50.
パッキング４０は、装着凹部４１よりも外側に突出した突出部４０p1，４０p2を有する。突出部４０p1は、パッキング４０の上面側のみに位置する薄い板状である。突出部４０p2は、パッキング４０の上面側に位置する板状部４０p21と、板状部４０p21と一体的に連結した肉厚部４０p22とよりなる。肉厚部４０p22は、壁４５，４６の間隔よりも狭い幅を有し、底面４０Ｂから板状部４０p21までの高さを有する。肉厚部４０p22は、壁４４の外面と一体的に連結されている。 The packing 40 has protrusions 40p1 and 40p2 that protrude outward from the mounting recess 41. The protrusion 40p1 is a thin plate located only on the upper surface side of the packing 40. The protruding portion 40p2 includes a plate-like portion 40p21 located on the upper surface side of the packing 40, and a thick portion 40p22 integrally connected to the plate-like portion 40p21. The thick portion 40p22 has a width narrower than the interval between the walls 45 and 46, and has a height from the bottom surface 40B to the plate-like portion 40p21. The thick portion 40p22 is integrally connected to the outer surface of the wall 44.
パッキング４０を電池収納部10h50に収納すると、肉厚部４０p22の外面は筐体１０の下面１４の内面に接触し、壁４５は側面１５の内面に接触し、壁４６は側面１６の内面に接触する。壁４３は、隔壁板３０に形成した段差部３２に接触する。 When the packing 40 is stored in the battery storage unit 10h50, the outer surface of the thick portion 40p22 contacts the inner surface of the lower surface 14 of the housing 10, the wall 45 contacts the inner surface of the side surface 15, and the wall 46 contacts the inner surface of the side surface 16. To do. The wall 43 contacts the stepped portion 32 formed on the partition plate 30.
パッキング４０の１つの角部にはコネクタ５１及びケーブル５２を下方へと引き出すための開口部４２が形成されている。開口部４２は、装着凹部４１を部分的に切り欠くようにして突出部４０p1に形成されている。開口部４２が形成されていることによって、壁４３と壁４５とは連結していない。従って、装着凹部４１は、開口部４２側には底面角部が存在しない。 An opening 42 for pulling out the connector 51 and the cable 52 downward is formed at one corner of the packing 40. The opening 42 is formed in the protrusion 40p1 so as to partially cut out the mounting recess 41. Since the opening 42 is formed, the wall 43 and the wall 45 are not connected. Accordingly, the mounting recess 41 has no bottom corner on the opening 42 side.
装着凹部４１は、底面４０Ｂと壁４３，４６とによって形成される底面角部４１ｅと、底面４０Ｂと壁４４，４６とによって形成される図４では見えていない底面角部と、底面４０Ｂと壁４４，４５とによって形成される図４では見えていない底面角部とを有する。便宜上、図４では見えていない底面角部も底面角部４１ｅと称することとする。即ち、装着凹部４１は、３つの底面角部４１ｅを有する。 The mounting recess 41 includes a bottom corner 41e formed by the bottom surface 40B and the walls 43, 46, a bottom corner formed by the bottom surface 40B and the walls 44, 46, which is not visible in FIG. 4, a bottom surface 40B, and a wall. And the bottom corners not visible in FIG. For convenience, the bottom corner that is not visible in FIG. 4 is also referred to as a bottom corner 41e. That is, the mounting recess 41 has three bottom corners 41e.
パッキング４０の上面には、３つの底面角部４１ｅそれぞれに対応して、底面角部４１ｅの位置よりも装着凹部４１の内側へと突出した押さえ部４７が形成されている。３つの押さえ部４７の先端部は、それぞれ、壁４３，４６双方に対して４５度で傾斜する線分、壁４４，４６双方に対して４５度で傾斜する線分、壁４４，４５双方に対して４５度で傾斜する線分となっている。 On the upper surface of the packing 40, a pressing portion 47 is formed corresponding to each of the three bottom corner portions 41 e and projecting inward of the mounting recess 41 from the position of the bottom corner portion 41 e. The tip portions of the three pressing portions 47 are respectively formed on a line segment inclined at 45 degrees with respect to both the walls 43 and 46, a line segment inclined at 45 degrees with respect to both the walls 44 and 46, and both the walls 44 and 45. On the other hand, it is a line segment inclined at 45 degrees.
また、開口部４２の近傍の壁４５の上面には、装着凹部４１の内側へと突出した押さえ部４８が形成されている。押さえ部４８は、壁４５より略三角形状に突出している。上記のように、開口部４２が形成されていることによって壁４３と壁４５とが連結しておらず、開口部４２側には底面角部が存在しないため、底面角部４１ｅ上方の押さえ部４７の代わりに押さえ部４８を設けている。 In addition, on the upper surface of the wall 45 in the vicinity of the opening 42, a pressing portion 48 that protrudes to the inside of the mounting recess 41 is formed. The pressing portion 48 protrudes from the wall 45 in a substantially triangular shape. As described above, because the opening 42 is formed, the wall 43 and the wall 45 are not connected, and there is no bottom corner on the side of the opening 42. Therefore, the pressing portion above the bottom corner 41e. A pressing portion 48 is provided instead of 47.
パッキング４０の最外周部には、パッキング４０の外周端部を取り囲むように、底面４０Ｂ側に突出したリブ４０ｂが形成されている。パッキング４０を筐体１０に装着した状態では、リブ４０ｂは筐体１０側に突出している。 A rib 40b protruding toward the bottom surface 40B is formed on the outermost peripheral portion of the packing 40 so as to surround the outer peripheral end portion of the packing 40. In a state where the packing 40 is attached to the housing 10, the rib 40 b protrudes toward the housing 10.
図５は、図４のＢ−Ｂ断面図である。図６は、パッキング４０を裏面から見た平面図である。図６に示すように、パッキング４０の外周端部には、リブ４０ｂに隣接した凹部４０ｃが形成されている。 5 is a cross-sectional view taken along the line BB in FIG. FIG. 6 is a plan view of the packing 40 as seen from the back side. As shown in FIG. 6, a recess 40 c adjacent to the rib 40 b is formed at the outer peripheral end of the packing 40.
図５に示すように、壁４５，４６に沿った部分では、壁４５，４６とリブ４０ｂとの隙間が凹部４０ｃとなっている。図６に示すように、突出部４０p1，４０p2には、リブ４０ｂと平行して底面４０Ｂ側に突出したリブ４０ｄが形成され、リブ４０ｂとリブ４０ｄとの隙間が凹部４０ｃとなっている。リブ４０ｄは、リブ４０ｂよりも若干高く突出している。 As shown in FIG. 5, in the part along the walls 45 and 46, the clearance gap between the walls 45 and 46 and the rib 40b becomes the recessed part 40c. As shown in FIG. 6, the protrusions 40p1 and 40p2 are formed with ribs 40d protruding to the bottom surface 40B side in parallel with the ribs 40b, and the gaps between the ribs 40b and the ribs 40d form the recesses 40c. The rib 40d protrudes slightly higher than the rib 40b.
図７は、パッキング４０の装着凹部４１に電池５０を装着して両者を一体化した状態を示している。図７に示すように、装着凹部４１に装着された電池５０の上面には、押さえ部４７，４８が接触している。装着凹部４１の深さを電池５０の厚さとほぼ同じとしておけば、電池５０は、底面４０Ｂと壁４３〜４６と押さえ部４７，４８とによって囲まれて保持される。 FIG. 7 shows a state where the battery 50 is mounted in the mounting recess 41 of the packing 40 and the both are integrated. As shown in FIG. 7, the holding portions 47 and 48 are in contact with the upper surface of the battery 50 mounted in the mounting recess 41. If the depth of the mounting recess 41 is substantially the same as the thickness of the battery 50, the battery 50 is surrounded and held by the bottom surface 40 </ b> B, the walls 43 to 46, and the pressing portions 47 and 48.
電池５０の面内の１つの方向（例えば壁４３，４４に沿った方向）をＸ方向、電池５０の面内でＸ方向と直交する方向（例えば壁４５，４６に沿った方向）をＹ方向とし、電池５０の厚さ方向をＺ方向とすると、パッキング４０は、Ｘ方向，Ｙ方向，Ｚ方向の全ての方向で電池５０にかかる衝撃を吸収しつつ、電池５０を保護する。 One direction in the plane of the battery 50 (for example, the direction along the walls 43 and 44) is the X direction, and a direction perpendicular to the X direction in the plane of the battery 50 (for example, the direction along the walls 45 and 46) is the Y direction. Assuming that the thickness direction of the battery 50 is the Z direction, the packing 40 protects the battery 50 while absorbing the impact applied to the battery 50 in all the X, Y, and Z directions.
図８は、筐体１０内に回路基板２０から電池５０までを収納して、ねじ孔１７ａ〜１７ｄによって裏蓋６０を筐体１０に締め付けて構成した電子機器を切断した断面図である。図８は、図４のＢ−Ｂに相当する位置で電子機器を切断した断面図である。図９は、図８における左上角部を拡大した拡大部分断面図であり、（ａ）は裏蓋６０を締め付ける前の状態、（ｂ）は裏蓋６０を締め付けた状態を示している。 FIG. 8 is a cross-sectional view of an electronic device in which the circuit board 20 to the battery 50 are housed in the housing 10 and the back cover 60 is fastened to the housing 10 by the screw holes 17a to 17d. 8 is a cross-sectional view of the electronic device cut at a position corresponding to BB in FIG. 9 is an enlarged partial cross-sectional view in which the upper left corner in FIG. 8 is enlarged. (A) shows a state before the back cover 60 is tightened, and (b) shows a state in which the back cover 60 is tightened.
図９の（ａ）に示すように、電池収納部10h50に、装着凹部４１に電池５０を収納したパッキング４０を収納すると、筐体１０に形成したリブ１２ｂとパッキング４０に形成した凹部４０ｃとが係合する。 As shown in FIG. 9A, when the packing 40 storing the battery 50 in the mounting recess 41 is stored in the battery storage portion 10h50, the rib 12b formed in the housing 10 and the recess 40c formed in the packing 40 are formed. Engage.
図９の（ａ）より分かるように、裏蓋６０の内面角部はテーパ状となっている。裏蓋６０の内面とは、パッキング４０と対向する側の面である。裏蓋６０を、電池５０を収納したパッキング４０に被せてねじ孔１７ａ〜１７ｄによって筐体１０に締め付けて、裏蓋６０を筐体１０に取り付けると、図９の（ｂ）に示すように、テーパ状となっている裏蓋６０の内面角部がパッキング４０の直角状の角部をつぶしながらパッキング４０を押さえ込む。 As can be seen from FIG. 9A, the inner corner of the back cover 60 is tapered. The inner surface of the back cover 60 is a surface on the side facing the packing 40.
