以上が充電器１０の構成である。
次に、バッテリー装置５の構成を説明する。 As shown in FIG. 11, the main body case 18 is provided with an input connector 44 for inputting power to the charger 10 from an external power source such as a home AC power source. A belt 45 for binding the input AC cord 59 is attached to one side of the main body case 18, and the belt 45 is formed of a hook-and-loop fastener. The input AC cord 59 is a cord for connecting an external power source such as a household AC power source and the charger 10, and has connection portions 60 and 61 at both ends, respectively.
The above is the configuration of the charger 10.
Next, the configuration of the battery device 5 will be described.

図１２，図１３に示すように、バッテリー装置５は、バッテリーケース５２と、バッテリーケース５２内に収納されたリチウムイオン電池等の二次電池５３とを有している。バッテリーケース５２は、底部に、四角形の接続部５４を有している。差込部５１は接続部５４の底面に設けられている。尚、接続部５４にはスリット５５が形成されている。
以下、上記構成における作用を説明する。 As shown in FIGS. 12 and 13, the battery device 5 includes a battery case 52 and a secondary battery 53 such as a lithium ion battery housed in the battery case 52. The battery case 52 has a rectangular connection portion 54 at the bottom. The insertion part 51 is provided on the bottom surface of the connection part 54. A slit 55 is formed in the connection portion 54.
Hereinafter, the operation of the above configuration will be described.

充電器１０を使用してバッテリー装置５を充電する場合、先ず、バッテリー装置５を電動自転車１の車体フレーム４から取り外す。そして、図１２に示すように、入力用ＡＣコード５９の一方の接続部６０を充電器１０の入力用コネクタ４４に接続し、他方の接続部６１を家庭用の交流電源等の外部電源６２に接続する。   When charging the battery device 5 using the charger 10, first, the battery device 5 is removed from the body frame 4 of the electric bicycle 1. Then, as shown in FIG. 12, one connecting portion 60 of the input AC cord 59 is connected to the input connector 44 of the charger 10, and the other connecting portion 61 is connected to an external power source 62 such as a home AC power source. Connecting.

次に、出力コード１４を収納溝４２から取り出した後、図８，図９に示すように、受け部２９に嵌っている突部２６を中心にして、充電用コネクタ１５を一方向Ｂへ回動する。これにより、係止片２７が被係止部３５から離脱し、取付用座４０が収納溝４２の他端部から外方へ離脱する。その後、図３に示すように、突部２６を受け部２９から離脱させることにより、充電用コネクタ１５が本体ケース１８から取り外される。   Next, after the output cord 14 is taken out from the storage groove 42, as shown in FIGS. 8 and 9, the charging connector 15 is rotated in one direction B around the protrusion 26 fitted to the receiving portion 29. Move. As a result, the locking piece 27 is detached from the locked portion 35, and the mounting seat 40 is detached outward from the other end portion of the storage groove 42. Thereafter, as shown in FIG. 3, the charging connector 15 is detached from the main body case 18 by removing the protrusion 26 from the receiving portion 29.

このように、充電用コネクタ１５を本体ケース１８から取り外すためには、充電用コネクタ１５を回動する必要があるため、本体ケース１８に取り付けられた充電用コネクタ１５が不用意に本体ケース１８から外れてしまうのを防止することができる。   Thus, in order to remove the charging connector 15 from the main body case 18, it is necessary to rotate the charging connector 15, so that the charging connector 15 attached to the main body case 18 is inadvertently removed from the main body case 18. It can be prevented from coming off.

その後、図１２〜図１５に示すように、充電用コネクタ１５の充電用端子１６をバッテリー装置５の差込部５１に差し込む。これにより、家庭用の交流電源等の外部電源６２から得られる電力は、充電器１０に供給され、充電器１０において交流から直流に変換されると共に所定の電圧に変換されて、充電器１０からバッテリー装置５に供給されて、バッテリー装置５が充電される。   Thereafter, as shown in FIGS. 12 to 15, the charging terminal 16 of the charging connector 15 is inserted into the insertion portion 51 of the battery device 5. Thereby, the electric power obtained from the external power source 62 such as a home AC power source is supplied to the charger 10, and is converted from AC to DC in the charger 10 and also converted into a predetermined voltage. The battery device 5 is charged by being supplied to the battery device 5.

充電の際、充電用コネクタ１５の差込片２８がバッテリー装置５のスリット５５に差込まれ、バッテリー装置５の接続部５４が充電用コネクタ１５の第１および第２の案内板２２，２３間に入り込むため、充電用コネクタ１５がバッテリー装置５に対して幅方向Ｗへずれるのを防止することができ、また、第３の案内板２４が接続部５４の一面５４ａに面接触するため、充電用コネクタ１５がバッテリー装置５に対して一方向Ｃへずれるのを防止することができる。   During charging, the insertion piece 28 of the charging connector 15 is inserted into the slit 55 of the battery device 5, and the connecting portion 54 of the battery device 5 is between the first and second guide plates 22, 23 of the charging connector 15. Therefore, the charging connector 15 can be prevented from shifting in the width direction W with respect to the battery device 5, and the third guide plate 24 is in surface contact with the one surface 54 a of the connecting portion 54. The connector 15 can be prevented from shifting in one direction C with respect to the battery device 5.

尚、図１６に示すように、充電用端子１６の差込部５１への差し込みが不十分であると、充電用コネクタ１５とバッテリー装置５との間に隙間５７が発生する場合がある。万一、薄い金属板等の異物５８が隙間５７に侵入しても、異物５８は、充電用端子１６に達する前に異物接触防止用突起１７に当接し、充電用端子１６への接近が妨げられる。これにより、異物５８が充電用端子１６に接触するのを防止することができ、ショート等の不具合の発生を防止することができる。   As shown in FIG. 16, when the charging terminal 16 is not sufficiently inserted into the insertion portion 51, a gap 57 may be generated between the charging connector 15 and the battery device 5. Even if a foreign object 58 such as a thin metal plate enters the gap 57, the foreign object 58 abuts against the foreign object contact prevention protrusion 17 before reaching the charging terminal 16 and prevents access to the charging terminal 16. It is done. Thereby, it can prevent that the foreign material 58 contacts the charging terminal 16, and generation | occurrence | production of malfunctions, such as a short circuit, can be prevented.

また、図１０に示すように、他方のブッシング３８は本体ケース１８の一側面１８ａに対して外側方へ所定角度Ａだけ傾斜しているため、出力コード１４の他端部の根元の捻れを少なくすることができる。
バッテリー装置５の充電が完了した後、図１２，図１３に示すように、充電用コネクタ１５の充電用端子１６をバッテリー装置５の差込部５１から脱抜する。 Also, as shown in FIG. 10, the other bushing 38 is inclined outward by a predetermined angle A with respect to the one side surface 18a of the main body case 18, so that the twist of the other end of the output cord 14 is reduced. can do.
After the charging of the battery device 5 is completed, the charging terminal 16 of the charging connector 15 is removed from the insertion portion 51 of the battery device 5 as shown in FIGS.

充電器１０を使用しない場合、図８に示すように、充電用コネクタ１５の突部２６を本体ケース１８の受け部２９に嵌めた後、突部２６を中心に充電用コネクタ１５を他方向Ｄへ回動する。   When the charger 10 is not used, as shown in FIG. 8, after fitting the protrusion 26 of the charging connector 15 into the receiving portion 29 of the main body case 18, the charging connector 15 is moved in the other direction D around the protrusion 26. To turn.

これにより、係止片２７が被係止部３５に係止され、図９の仮想線で示すように、取付用座４０が収納溝４２の他端部に嵌入され、図６，図７に示すように、充電用端子１６と異物接触防止用突起１７とが収納部３３に収納され、図２に示すように、充電用コネクタ１５が本体ケース１８に取り付けられる。   As a result, the locking piece 27 is locked to the locked portion 35, and the mounting seat 40 is fitted into the other end of the storage groove 42 as shown by the phantom line in FIG. As shown in FIG. 2, the charging terminal 16 and the foreign object contact prevention protrusion 17 are housed in the housing portion 33, and the charging connector 15 is attached to the main body case 18 as shown in FIG. 2.

これにより、ケース部材１２が本体ケース１８と充電用コネクタ１５とで構成されるとともに、充電用端子１６がケース部材１２内に収納される。したがって、充電用コネクタ１５が直方体形状のケース部材１２の一部を構成することになり、開閉自在な蓋をケース部材１２に設けることを不要にすることができ、部品点数を減らすことが可能となる。   Thereby, the case member 12 is constituted by the main body case 18 and the charging connector 15, and the charging terminal 16 is accommodated in the case member 12. Accordingly, the charging connector 15 constitutes a part of the rectangular parallelepiped case member 12, and it is possible to eliminate the need to provide the case member 12 with an openable / closable lid, thereby reducing the number of components. Become.

また、充電用コネクタ１５を本体ケース１８に取り付けた際、図５，図９の仮想線に示すように、取付用座４０が収納溝４２の他端部に嵌入される。この際、図９に示すように、充電用コネクタ１５を他方向Ｄに回動することにより、取付用座４０の上端部が収納溝４２内の上面に当接し、充電用コネクタ１５が他方向Ｄへさらに回動すると、取付用座４０は、収納溝４２内の上面によって一旦下方へ押し付けられた後、仮想線で示すように収納溝４２内の奥へ達する。このため、取付用座４０が不用意に一方向Ｂへ回動して収納溝４２から外部へ離脱してしまうのを防止することができ、充電用コネクタ１５が不用意に本体ケース１８から外れてしまうのを防止することができる。   Further, when the charging connector 15 is attached to the main body case 18, the attachment seat 40 is fitted into the other end of the storage groove 42 as shown by the phantom lines in FIGS. 5 and 9. At this time, as shown in FIG. 9, by rotating the charging connector 15 in the other direction D, the upper end portion of the mounting seat 40 abuts on the upper surface in the storage groove 42, and the charging connector 15 is moved in the other direction. When the mounting seat 40 is further rotated to D, the mounting seat 40 is once pressed downward by the upper surface of the storage groove 42 and then reaches the back of the storage groove 42 as indicated by a virtual line. Therefore, it is possible to prevent the mounting seat 40 from inadvertently rotating in one direction B and detaching from the storage groove 42 to the outside, and the charging connector 15 is inadvertently detached from the main body case 18. Can be prevented.

さらに、図２，図５に示すように、出力コード１４を収納溝４２に収納することにより、出力コード１４がケース部材１２の外側方へはみ出すのを防止することができる。この際、出力コード１４はリブ４３によって収納溝４２内に固定されるため、出力コード１４が不用意に収納溝４２から外部へ出てしまうことはない。尚、取付用座４０を一方の係合部として利用し、収納溝４２を他方の係合部として利用することにより、さらに部品点数を減らすことができる。   Further, as shown in FIGS. 2 and 5, by storing the output cord 14 in the storage groove 42, it is possible to prevent the output cord 14 from protruding outward from the case member 12. At this time, since the output cord 14 is fixed in the storage groove 42 by the rib 43, the output cord 14 does not accidentally go out of the storage groove 42. Note that the number of parts can be further reduced by using the mounting seat 40 as one engaging portion and using the storage groove 42 as the other engaging portion.

また、入力用ＡＣコード５９の一方の接続部６０を充電器１０の入力用コネクタ４４から取り外し、他方の接続部６１を家庭用の交流電源等の外部電源６２から取り外した後、図１１に示すように、入力用ＡＣコード５９をベルト４５で本体ケース１８の一側面に結束することができる。   Further, after one connection portion 60 of the input AC cord 59 is removed from the input connector 44 of the charger 10 and the other connection portion 61 is removed from the external power source 62 such as a home AC power source, it is shown in FIG. In this way, the input AC cord 59 can be bound to one side surface of the main body case 18 by the belt 45.

また、充電電圧の異なった複数機種の充電器１０がある場合、図１３に示した充電器１０の差込片２８は、各機種ごとに、異なった位置に設けられている。これにより、例えば充電電圧が２４ボルト用の充電器１０を用いて２４ボルト用のバッテリー装置５を充電する際、充電用コネクタ１５の差込片２８の位置がバッテリー装置５のスリット５５の位置に合致するため、差込片２８をスリット５５に差し込むことができる。しかしながら、誤って、３６ボルト用の充電器１０を用いて２４ボルト用のバッテリー装置５を充電しようとすると、差込片２８の位置がスリット５５の位置に合致せず、このため、差込片２８をスリット５５に差し込むことができず、３６ボルト用の充電器１０の充電用端子１６を２４ボルト用のバッテリー装置５の差込部５１に差し込むことはできない。これにより、バッテリー装置５の充電電圧と異なった充電電圧の充電器１０で充電するといった誤充電を防止することができる。尚、上記充電電圧の数値は一例であって、これらの数値に限定されるものではない。   When there are a plurality of types of chargers 10 having different charging voltages, the insertion piece 28 of the charger 10 shown in FIG. 13 is provided at a different position for each model. Thus, for example, when charging the battery device 5 for 24 volts using the charger 10 having a charging voltage of 24 volts, the position of the insertion piece 28 of the charging connector 15 is set to the position of the slit 55 of the battery device 5. In order to match, the insertion piece 28 can be inserted into the slit 55. However, if the battery device 5 for 24 volts is charged by mistake using the charger 10 for 36 volts, the position of the insertion piece 28 does not match the position of the slit 55, and therefore the insertion piece 28 cannot be inserted into the slit 55, and the charging terminal 16 of the 36 volt charger 10 cannot be inserted into the insertion portion 51 of the battery device 5 for 24 volt. Thereby, it is possible to prevent erroneous charging such as charging with the charger 10 having a charging voltage different from the charging voltage of the battery device 5. In addition, the numerical value of the said charging voltage is an example, Comprising: It is not limited to these numerical values.

上記実施の形態では、充電可能な電池である二次電池を本体ケース１８に内蔵していない充電器１０を示したが、二次電池を本体ケース１８に内蔵した充電器１０であってもよい。この場合、外部電源６２から供給される電力を一旦充電器１０の二次電池に蓄え、充電器１０の二次電池の電力をバッテリー装置５に出力してバッテリー装置５を充電するものであってもよい。   In the above embodiment, the charger 10 in which the secondary battery, which is a rechargeable battery, is not built in the main body case 18 is shown. However, the charger 10 in which the secondary battery is built in the main body case 18 may be used. . In this case, the power supplied from the external power source 62 is temporarily stored in the secondary battery of the charger 10, and the power of the secondary battery of the charger 10 is output to the battery device 5 to charge the battery device 5. Also good.

上記実施の形態では、充電対象機器の一例として、電動自転車１のバッテリー装置５を挙げたが、電動自転車１に限定されるものではなく、電動自転車１以外の車両に搭載されるバッテリー装置又は車両以外の機器に備えられるバッテリー装置を充電するものであってもよい。   In the above-described embodiment, the battery device 5 of the electric bicycle 1 has been described as an example of the charging target device. However, the battery device 5 is not limited to the electric bicycle 1, but is mounted on a vehicle other than the electric bicycle 1. You may charge the battery apparatus with which apparatuses other than are charged.
