また、以下の特許文献３には、円筒型二次電池の外周面に、可撓性の太陽電池を設置して、太陽電池にて、二次電池を充電する構造が、開示されている。
実公昭58-661号 実公昭54-44730号 実開平2-61067号 Patent Document 3 below discloses a structure in which a flexible solar battery is installed on the outer peripheral surface of a cylindrical secondary battery, and the secondary battery is charged by the solar battery.
No. 58-661 No. 54-44730 ACT 2-61067

外周面に太陽電池を設けた二次電池を、スペーサに取り付けた状態で、保管するなら、スペーサにより、太陽電池への太陽光等の光の入射が遮られるので、太陽電池による二次電池への充電はできなくなる。   If you store a secondary battery with a solar cell on the outer peripheral surface attached to the spacer, the spacer will block the incidence of light, such as sunlight, on the solar cell. Can no longer be charged.

本発明は、このような問題点を解決するために成されたものであり、効率良く充電できる太陽電池の配置構造を提供することを目的とする。   The present invention has been made to solve such problems, and an object of the present invention is to provide a solar cell arrangement structure that can be efficiently charged.

本発明は、内部に円柱状の二次電池を保持する機構を備える筒状体の電池用スペーサであって、前記筒状体の外周面に太陽電池を備えることを特徴とする。また、前記二次電池の直径よりも大きな直径を備える円筒状体の電池用スペーサであることを特徴とする。   The present invention is a cylindrical battery spacer provided with a mechanism for holding a cylindrical secondary battery therein, and is characterized in that a solar battery is provided on the outer peripheral surface of the cylindrical body. Further, the battery spacer is a cylindrical battery having a diameter larger than that of the secondary battery.

本発明においては、電池用スペーサの外周面に太陽電池を設置しているので、二次電池を電池用スペーサに保持した状態で保管しても、光を太陽電池に入射させ２次電池を充電することができる。二次電池の直径よりも、電池用スペーサは大きな直径を備えていることより、二次電池の外周面の概略全周或いは一部に太陽電池を設定する場合と比較して、電池用スペーサの外周面は広い面積となるので、必要に応じて、大きな面積に太陽電池を設置することができる。大きな面積の太陽電池は、大きな出力にて、二次電池を充電することができる。   In the present invention, since the solar battery is installed on the outer peripheral surface of the battery spacer, even if the secondary battery is stored in a state of being held by the battery spacer, light is incident on the solar battery to charge the secondary battery. can do. Since the battery spacer has a larger diameter than the diameter of the secondary battery, the battery spacer has a larger diameter than the case where the solar battery is set on the entire circumference or a part of the outer peripheral surface of the secondary battery. Since the outer peripheral surface has a wide area, the solar cell can be installed in a large area as necessary. A large-area solar cell can charge a secondary battery with a large output.

本実施例を、図面を用いて説明する。電池用スペーサＡは、単３型円柱状二次電池１を、単１型電池として利用できるように、円筒状体１０の形状を備えている。このような二次電池１としては、Ni-Cd電池、Ni水素電池等が利用することができる。円筒状体１０の側壁面には、略全体に、可撓性を有する太陽電池Ｓが設定している。   This embodiment will be described with reference to the drawings. The battery spacer A has the shape of the cylindrical body 10 so that the AA columnar secondary battery 1 can be used as an AA type battery. As such a secondary battery 1, a Ni-Cd battery, a Ni hydrogen battery, etc. can be utilized. A flexible solar cell S is set on the side wall surface of the cylindrical body 10 almost entirely.

この円筒状体１０は、樹脂材料からなり、外周面である外周面体１１、円板型の上面である上面体１２、円板型の下面である下面体１３を備えている。   The cylindrical body 10 is made of a resin material and includes an outer peripheral surface body 11 that is an outer peripheral surface, an upper surface body 12 that is an upper surface of a disk type, and a lower surface body 13 that is a lower surface of the disk type.

上面体１２は、外側中心部に、金属材料からなる円柱型の正極端子１２＋が設けられており、これと電気接続した状態で、上面体１２の裏面側に、金属板状の弾性端子１２Ｒを備えている。この弾性端子１２Ｒの一端が延長して、正極端子１２＋と接触して、電気接続している。また、太陽電池Ｓからの電流が、二次電池１への方向のみに供給できるように、逆流防止ダイオードＤを太陽電池Ｓのプラス出力端子との間に、接続している（図面において詳細な配線は省略してある）。   The upper surface body 12 is provided with a cylindrical positive electrode terminal 12+ made of a metal material in the center of the outer side, and a metal plate-like elastic terminal 12R is provided on the back surface side of the upper surface body 12 in an electrically connected state. I have. One end of the elastic terminal 12R is extended to be in contact with the positive terminal 12+ to be electrically connected. Further, the backflow prevention diode D is connected between the positive output terminal of the solar cell S so that the current from the solar cell S can be supplied only in the direction toward the secondary battery 1 (detailed in the drawing). Wiring is omitted).

二次電池１がスペーサＡの内部に保持された状態で、二次電池１の正極１＋と弾性端子１２Ｒが接触しており、弾性端子１２Ｒの先端側にて、下側に付勢できるように、弾性端子１２Ｒは弾性力を備えている。   In a state where the secondary battery 1 is held inside the spacer A, the positive electrode 1+ of the secondary battery 1 and the elastic terminal 12R are in contact with each other, and can be urged downward on the tip side of the elastic terminal 12R. The elastic terminal 12R has an elastic force.

下面体１３より内部に、内部底面体１４が設けられており、二次電池１を挿入、保持するために、円形の開口１４Ｈを備えている。そして、下面体１３は、回転してスライドするために、中心よりずれた位置に、円柱状の突起体１３Ｐを備え、この突起体１３Ｐを、内部底面体１４の円形開口１４Ｈに嵌入している。また、下面体１３の下側には、金属材料からなる円板状の負極端子１３−が設けられ、これと電気接続した状態で、下面体１３の内側には、金属板状の端子配線１３Ｒが設けられ、負極端子１３−と端子配線１３Ｒとは、一体となって電気接続している。二次電池１の負極１−と接触するために、端子配線１３Ｒの先端は、突起形状１３ＲＰとなっている。端子配線１３Ｒの他端側は、下面体１３の突起体１３Ｐの中心部を貫通して、端子配線１３Ｒの他端１３ＲＴが突起体１３Ｐの内側の表面に露出して設けられている。そして、端子配線１３Ｒの他端１３ＲＴと、太陽電池Ｓのマイナス端子とは、撚線であるリード線１５等の半田付け等により電気接続されている（図面において詳細な配線は省略してある）。ここでリード線１５は、コイル状部を備えていて寸法的に余裕があるので、突起体１３Ｐを中心にして回転して下面体１３が開閉しても、端子配線１３Ｒの他端１３ＲＴが回転しても、半田付け等が、外れることはない。このような撚線のリード線による電気接続に代えて、他端１３ＲＴの表面に、弾性力を備える金属体が押圧して接触することで、他端１３ＲＴが回転しても電気接続を維持できる構造とすることもできる。   An inner bottom surface 14 is provided inside the lower surface body 13, and a circular opening 14 </ b> H is provided for inserting and holding the secondary battery 1. In order to rotate and slide, the lower surface body 13 includes a cylindrical protrusion 13P at a position shifted from the center, and the protrusion 13P is fitted into the circular opening 14H of the inner bottom surface body 14. . Further, a disk-shaped negative electrode terminal 13- made of a metal material is provided below the lower surface body 13, and in a state of being electrically connected thereto, a metal plate-shaped terminal wiring 13R is formed inside the lower surface body 13. And the negative electrode terminal 13- and the terminal wiring 13R are electrically connected together. In order to contact the negative electrode 1 of the secondary battery 1, the tip of the terminal wiring 13 </ b> R has a protruding shape 13 </ b> RP. The other end side of the terminal wiring 13R passes through the center portion of the protrusion 13P of the lower surface body 13, and the other end 13RT of the terminal wiring 13R is exposed on the inner surface of the protrusion 13P. The other end 13RT of the terminal wiring 13R and the negative terminal of the solar cell S are electrically connected by soldering the lead wire 15 or the like which is a stranded wire (detailed wiring is omitted in the drawing). . Here, since the lead wire 15 has a coil-like portion and has a dimensional margin, the other end 13RT of the terminal wiring 13R is rotated even if the lower surface body 13 is opened and closed by rotating around the protrusion 13P. Even so, soldering etc. will not come off. Instead of electrical connection using such a stranded lead wire, a metal body having an elastic force is pressed and brought into contact with the surface of the other end 13RT, so that the electrical connection can be maintained even when the other end 13RT rotates. It can also be a structure.

また、内部底面体１４の開口１４Ｈに連続して、円筒状の保持部１６が設けれており、この保持部１６内の空間は、直径が、二次電池１が挿入できる寸法になっている。円筒状の形状の高さは、図２では、二次電池１の高さ程度まであるが、これに代わって、二次電池１の高さの半分程度まで小さくすることも可能である。   Further, a cylindrical holding portion 16 is provided continuously to the opening 14H of the inner bottom surface body 14, and the diameter of the space in the holding portion 16 is such that the secondary battery 1 can be inserted. . Although the height of the cylindrical shape is about the height of the secondary battery 1 in FIG. 2, it can be reduced to about half the height of the secondary battery 1 instead.

下面体１３を、図２のように、回転してスライドさせたで、二次電池１を保持部１６内の空間に挿入する。そして、図１に示すように、下面体１３を回転して閉めた状態において、二次電池１は、電池用スペーサＡの内部に、保持機構により保持される。保持機構は、図面に開示されるように、上面体１２及び弾性端子１２Ｒ、外周面体１１及び保持部１６、内部底面体１４及び下面体１３及び端子配線１３Ｒ等の配置、構造による機構であって、二次電池１を保持している。   Since the lower surface body 13 is rotated and slid as shown in FIG. 2, the secondary battery 1 is inserted into the space in the holding portion 16. As shown in FIG. 1, the secondary battery 1 is held inside the battery spacer A by the holding mechanism in a state where the lower surface body 13 is rotated and closed. As shown in the drawings, the holding mechanism is a mechanism based on the arrangement and structure of the upper surface body 12 and the elastic terminal 12R, the outer peripheral surface body 11 and the holding portion 16, the inner bottom surface body 14, the lower surface body 13, the terminal wiring 13R, and the like. The secondary battery 1 is held.

可撓性を有する太陽電池Ｓとしては、本出願人が出願した特開平７−２３１０１５号に開示されるように、耐熱性のポリイミド樹脂の基板上に、裏面電極層、アモルファスシリコン半導体層、受光面の透明電極層を積層した積層体Ｓ１〜Ｓ６であり、所望の出力電圧を得るために、同公報に開示されるように、複数の積層体を電気的に直列接続したものである。本実施例においては、このよう積層体Ｓ１〜Ｓ６を、スペーサＡの外周面体１１の円周方向に延在するように配置することにより、太陽電池Ｓに入射する光が、全周方向或いは周方向のある方向より光が入射しても、出力を安定してえることができる。、
また、図３に示すように、円板形の乱反射板Ｒの中心部にスペーサＡを配置することにより、入射する光を乱反射させて、効率良く、太陽電池Ｓに光を入射させることができる。ここで、乱反射板Ｒとしては、図３の拡大図（ｂ）に図示されるように、表面を高光反射性としたピラミッド状の構成要素Ｒ１を連続して配置したものを利用している。 As a flexible solar cell S, as disclosed in Japanese Patent Application Laid-Open No. 7-23310 filed by the present applicant, a back electrode layer, an amorphous silicon semiconductor layer, a light receiving layer on a heat-resistant polyimide resin substrate. In order to obtain a desired output voltage, a plurality of laminates are electrically connected in series as disclosed in the publication. In the present embodiment, the laminates S1 to S6 are arranged so as to extend in the circumferential direction of the outer peripheral surface 11 of the spacer A, so that the light incident on the solar cell S can be transmitted in the entire circumferential direction or the circumferential direction. Even if light enters from a certain direction, the output can be stably obtained. ,
In addition, as shown in FIG. 3, by arranging the spacer A in the center of the disk-shaped diffuse reflector R, the incident light can be diffusely reflected, and the light can be efficiently incident on the solar cell S. . Here, as the irregular reflection plate R, as shown in the enlarged view (b) of FIG. 3, a plate in which pyramid-shaped components R <b> 1 whose surface has high light reflectivity is continuously arranged is used.

本実施例では、スペーサＡの外周面体１１の全体に太陽電池Ｓを配置しているが、一部に配置することも可能である。   In the present embodiment, the solar cell S is arranged on the entire outer peripheral surface 11 of the spacer A, but it is also possible to arrange it on a part thereof.

また、スペーサＡは、円筒状体の外形を備えているが、単１型電池と互換性があるのであれば、多角柱状の筒状体であっても良い。このとき、スペーサの外周面は、多数の平面となるので、このような各平面に、板状の太陽電池を配置することができる。そして、配置された複数の板状の太陽電池を電気接続する。この場合、板状の太陽電池は、可撓性がなくても良い。   The spacer A has a cylindrical outer shape, but may be a polygonal cylindrical body as long as it is compatible with a single-type battery. At this time, since the outer peripheral surface of the spacer is a large number of planes, a plate-like solar cell can be arranged on each such plane. And the several plate-shaped solar cell arrange | positioned is electrically connected. In this case, the plate-like solar cell may not be flexible.
