Abstract
Description
本発明は、二次電池を充電する充電器の機構に関するものである。 The present invention relates to a mechanism of a charger for charging a secondary battery.
近年、ポータブルオーディオやデジタルスチルカメラといった携帯可能な電子機器の市場が急速に伸びている。そんな中、携帯型電子機器に電源を供給するための充電型電池及び充電器は重要な役割を担っている。 In recent years, the market for portable electronic devices such as portable audio and digital still cameras has grown rapidly. Meanwhile, rechargeable batteries and chargers for supplying power to portable electronic devices play an important role.
しかしながら、充電型電池用の充電器は二次電池を充電した場合、電池自身および充電回路からの発熱により、安全上のために充電器のカバーがあったりすると、充電器内部に熱がたまりやすく、電池自身の寿命および性能の劣化、また充電可能な温度環境の確保に課題があった。 However, when a rechargeable battery charger is charged for a rechargeable battery, heat from the battery itself and the charging circuit may cause heat to accumulate inside the charger if there is a charger cover for safety reasons. However, there are problems in the deterioration of the life and performance of the battery itself and the securing of a temperature environment where charging is possible.
上述の課題を解決するために、従来の方法では、電池装着時に充電器の電池装着面と二次電池とを隔離するために段差を設け、また、周囲の側壁に切り欠きを設置し、充電時に生じる充電器と二次電池との間の熱を側壁の切り欠きから放熱させるようにしていた(例えば、特許文献1参照)。
しかしながら、上記従来の構成では、放熱路は側壁に切り欠き部として設置しているのみであるため、電池を充電している間、発熱面に対して、放熱用の空気の流出入方向が部分的な横方向となるために放熱効果は少なかった。 However, in the above conventional configuration, the heat radiation path is only installed as a notch on the side wall, so that the direction of the flow of heat in and out of the heat radiation surface is partially with respect to the heat generation surface while charging the battery. Therefore, the heat dissipation effect was small.
本発明は、この課題を解決するものであり、二次電池の充電の発熱を容易に放熱できるようにした充電器を提供することを目的とする。 The present invention solves this problem, and an object of the present invention is to provide a charger that can easily dissipate heat generated by charging a secondary battery.
上記目的を達成するために本発明の充電器は、充電回路を内蔵した本体に充電電池を収納する凹部を設けるとともに、この凹部を覆うカバーを開閉可能とした充電器において、上記凹部の少なくとも両端部に本体の底面に貫通する貫通穴を設けた構成としたものである。 In order to achieve the above object, a charger according to the present invention is provided with a recess for housing a rechargeable battery in a main body with a built-in charging circuit, and a cover that can open and close the cover, and at least both ends of the recess. In this configuration, a through-hole penetrating the bottom surface of the main body is provided in the part.
本発明によると、充電器の底部から貫通穴を作製し、充電器内部の空気の流出入を効率的に実施できるようにした。また、さらに、ケースの側面およびカバーにも切り欠き部を追加して、さらに空気の流れの効果を大きくして、放熱効果をあげることができた。 According to the present invention, a through hole is made from the bottom of the charger so that air can be efficiently flowed in and out of the charger. In addition, notches were added to the side and cover of the case to further increase the effect of air flow and increase the heat dissipation effect.
以下本発明を実施するための最良の形態について、図面を参照しながら説明する。 The best mode for carrying out the present invention will be described below with reference to the drawings.
図1は実施例の充電器を上面側から見た斜視図である。図1において1は充電器を示す。充電器1の外装は上ケース2、カバー3、および、下ケース4で構成されている。上ケース2には凹部である電池収納部5が形成されている。電池収納部5には上ケース2の穴部から充電制御用の基板に取り付けられた電池接続用のマイナス端子11及びプラス端子12が露出しており、電池収納部5に充電電池を入れると接続が可能となる。カバー3は
空気流出用の貫通穴7及び回転軸9を有し、回転軸9を軸に開閉が可能である。図1はカバー3が開いた状態を示している。
FIG. 1 is a perspective view of the charger of the embodiment as viewed from the upper surface side. In FIG. 1, 1 indicates a charger. The exterior of the charger 1 includes an upper case 2, a cover 3, and a lower case 4. The upper case 2 is formed with a battery housing portion 5 that is a recess. A battery connecting minus terminal 11 and a plus terminal 12 which are attached to a charging control board are exposed from the hole of the upper case 2 in the battery housing portion 5 and are connected when a rechargeable battery is inserted into the battery housing portion 5. Is possible. The cover 3 has a through-hole 7 for air outflow and a rotating shaft 9, and can be opened and closed around the rotating shaft 9. FIG. 1 shows a state in which the cover 3 is opened.
図2は実施例の充電器を底面側から見た斜視図である。図1、図2において6は貫通穴を示し、貫通穴6は電池収納部5の両端に有し、下ケース4の底面に貫通している。貫通穴6が下ケース4の底面に貫通することにより、電池挿入部5と底面側との空気の流出入が可能になると共に電池挿入部5に水などの異物が入った場合に底面側へ流出が可能となる。 FIG. 2 is a perspective view of the charger of the embodiment as seen from the bottom side. In FIGS. 1 and 2, reference numeral 6 denotes a through hole. The through hole 6 is provided at both ends of the battery housing 5 and passes through the bottom surface of the lower case 4. When the through hole 6 penetrates the bottom surface of the lower case 4, air can flow in and out between the battery insertion portion 5 and the bottom surface side, and when a foreign substance such as water enters the battery insertion portion 5, it moves to the bottom surface side. An outflow is possible.
図3は実施例の充電器に充電電池13を装着し、カバー3を閉めた状態の斜視図である。カバー3を閉めることにより、電池収納部5を覆うことが可能となる。また、カバー3には充電電池13aと13b,13bと13c,13cと13d間の谷の上に位置する部分に貫通穴7を設けている。充電電池間の谷の上に貫通穴7を設けることにより充電電池13とカバー3との間に空気の流出入経路を設けることが可能となる。また下ケース4には電池収納部5の側面に、切り欠き部8を有している。切り欠き部8を有することにより切り欠き部8の横に収納される充電電池13a及び13dの取り外しが容易となると共に、カバー3と切り欠き部8との間に隙間が生じる為、空気の流出が容易となる。 FIG. 3 is a perspective view of the battery charger 13 of the embodiment with the rechargeable battery 13 attached and the cover 3 closed. By closing the cover 3, it is possible to cover the battery housing 5. Further, the cover 3 is provided with a through hole 7 in a portion located on the valley between the rechargeable batteries 13a and 13b, 13b and 13c, and 13c and 13d. By providing the through hole 7 on the valley between the rechargeable batteries, it is possible to provide an air inflow / outflow path between the rechargeable battery 13 and the cover 3. Further, the lower case 4 has a notch portion 8 on the side surface of the battery housing portion 5. The notch 8 makes it easy to remove the rechargeable batteries 13a and 13d housed beside the notch 8, and a gap is formed between the cover 3 and the notch 8, so that air flows out. Becomes easy.
図4は実施例の充電器における充電中の空気の流出入を模式的に示す断面図である。充電器1の電池収納部5に充電電池13を収納してカバー3を閉め、充電を開始したときの空気の流れを図5に1点鎖線で示している。充電により温度上昇した充電電池13に対し、充電器1の底面から、貫通穴6を通り空気が流入する。流入した空気は充電電池13の表面を通りながら、充電電池13a及び13dの側面側にある切り欠き部8と電池カバー3との隙間及びカバー3の貫通穴7から抜ける為、充電電池13の表面を冷却する効果がある。 FIG. 4 is a cross-sectional view schematically showing air inflow and outflow during charging in the charger of the embodiment. The flow of air when the rechargeable battery 13 is accommodated in the battery accommodating portion 5 of the charger 1 and the cover 3 is closed and charging is started is shown by a one-dot chain line in FIG. Air flows from the bottom surface of the charger 1 through the through hole 6 to the rechargeable battery 13 whose temperature has risen due to charging. The inflowing air passes through the surface of the rechargeable battery 13 and escapes from the gap between the notch 8 on the side of the rechargeable batteries 13 a and 13 d and the battery cover 3 and the through hole 7 of the cover 3. Has the effect of cooling.
図5は実施例の充電器に上面から水が掛かった時の水の流出入を模式的に示す断面図である。充電器1の電池収納部5に充電電池13を収納してカバー3を閉めた状態で上面から水が掛かった場合の水の流れを図6に2点鎖線で示している。充電器1に上面から水が掛かった場合、カバー3の貫通穴7から電池収納部5へ入った水は両端にある下ケース4の底面に貫通する貫通穴6から直接排水される為、充電器内部に浸水する量が低減される効果がある。 FIG. 5 is a cross-sectional view schematically showing the inflow and outflow of water when water is applied to the charger of the embodiment from the upper surface. The flow of water when the rechargeable battery 13 is stored in the battery storage unit 5 of the charger 1 and the cover 3 is closed and water is applied from the upper surface is shown by a two-dot chain line in FIG. When water is applied to the charger 1 from the upper surface, the water that has entered the battery housing 5 from the through hole 7 of the cover 3 is drained directly from the through hole 6 that penetrates the bottom surface of the lower case 4 at both ends. There is an effect that the amount of water immersed in the vessel is reduced.
上述の効果を確認するために、周囲温度25℃の環境下で容量約2100mAh程度の単3形ニッケル水素電池を4本同時に平均電流750mAで充電する充電器を作成した。貫通穴6、貫通穴7及び切り欠き部8を有した場合と、貫通穴6、貫通穴7及び切り欠き部8を有しない場合とで4本の充電電池13a、13b、13c、13dの充電中における表面温度を測定した。 In order to confirm the above-mentioned effect, a battery charger for charging four AA nickel metal hydride batteries with a capacity of about 2100 mAh at an average current of 750 mA in an environment at an ambient temperature of 25 ° C. was prepared. Charging of the four rechargeable batteries 13a, 13b, 13c, and 13d when the through hole 6, the through hole 7 and the notch 8 are provided and when the through hole 6, the through hole 7 and the notch 8 are not provided The surface temperature inside was measured.
表1に示すように、実施形態に基づく、貫通穴6、貫通穴7、切り欠き部8を設けることにより、貫通穴6、貫通穴7、切り欠き部8を設けない場合に比べて充電電池13の表面温度が低く、放熱効果が高いことがわかる。 As shown in Table 1, by providing the through hole 6, the through hole 7, and the notch 8 based on the embodiment, the rechargeable battery is compared with the case where the through hole 6, the through hole 7, and the notch 8 are not provided. It can be seen that the surface temperature of 13 is low and the heat dissipation effect is high.
表1では充電電池の例えば単3形ニッケル水素電池4本入りで説明したが、充電器に用いられる電池の本数及び電池の種類に関係なく同様の効果が得られる。 Although Table 1 describes the case where four rechargeable batteries, for example, AA nickel metal hydride batteries are included, the same effect can be obtained regardless of the number of batteries and the type of batteries used in the charger.
また、熱の放熱効果の実験として、ケース材料をPPEとしたが、ABSなど他の樹脂材料系及びアルミ製などの金属系であっても同様の効果が得られる。 In addition, although the case material is PPE as an experiment of the heat radiation effect, the same effect can be obtained even when other resin material systems such as ABS and metal systems such as aluminum are used.
