１は前フレームで、該前フレーム１の前端部分には、前ホーク２や前車輪軸３などを介して前車輪４が支持されると共に、ハンドルステム５などを介してハンドル６が設けられている。前記ハンドルステム５は上下２分割に構成され、上下のハンドルステム５間に介在されるリンク機構７により、後述する折りたたみ状態で、ハンドル６が前フレーム１に対して後述する後フレーム７とは反対側に折りたたみ可能に連結されている。 Reference numeral 1 denotes a front frame, and a front wheel 4 is supported at a front end portion of the front frame 1 via a front fork 2 and a front wheel shaft 3 and a handle 6 is provided via a handle stem 5 and the like. Yes. The handle stem 5 is divided into upper and lower parts, and the handle 6 is opposite to the rear frame 7 described later with respect to the front frame 1 in a folded state described later by a link mechanism 7 interposed between the upper and lower handle stems 5. It is foldably connected to the side.
８は前記前フレーム１の後部に後述のリンク機構１３により連結される後フレームで、該後フレーム８の後端部分には、後車輪軸９などを介して後車輪１０が支持されると共に、前側部分には、サドル１１を支持するシートパイプ１２が設けられている。 8 is a rear frame connected to the rear portion of the front frame 1 by a link mechanism 13 which will be described later. A rear wheel 10 is supported on a rear end portion of the rear frame 8 via a rear wheel shaft 9 and the like. A seat pipe 12 that supports the saddle 11 is provided in the front portion.
１３は前記前フレーム１と後フレーム７とを連結するリンク機構で、両フレームを使用状態と折りたたみ状態との間を回動可能とすると共に、使用状態に選択的に保持する機構（図示せず）を具備している。前記リンク機構１３は、回動軸１４が図１に示すように本実施形態の折りたたみ式電動補助自転車を上方から見て後フレーム８の左側に配設されており、図１に示すように前記後フレーム７に対して前フレーム１を折りたたんだ状態で、前フレーム１が後フレーム７の左側に回動するように構成されている。 13 is a link mechanism that connects the front frame 1 and the rear frame 7, and is a mechanism (not shown) that enables both the frames to be rotated between the use state and the folded state and that is selectively held in the use state. ). As shown in FIG. 1, the link mechanism 13 is arranged on the left side of the rear frame 8 when the folding shaft 14 is viewed from above as shown in FIG. The front frame 1 is configured to rotate to the left side of the rear frame 7 with the front frame 1 folded with respect to the rear frame 7.
前記リンク機構１３の回動軸１４は、該回動軸１４と前記前車輪軸３との距離Ａと、回動軸１４と前記後車輪軸９との距離Ｂとの関係が、Ａ＜Ｂとなるように構成され、前記後車輪軸１０が後述する前車輪１のカバー体２２に接触しないように構成されている。 The rotation shaft 14 of the link mechanism 13 is such that the relationship between the distance A between the rotation shaft 14 and the front wheel shaft 3 and the distance B between the rotation shaft 14 and the rear wheel shaft 9 is A <B. The rear wheel shaft 10 is configured not to contact a cover body 22 of the front wheel 1 described later.
１５は前記後フレーム８の前部に設けられた脚部で、前記前フレーム１と後フレーム８とを折りたたんだ状態で地面に接地し、折りたたみ状態での後フレーム８前方側の脚部となり、使用状態では、地面に対して十分な間隔を有するように構成されている。 15 is a leg portion provided at the front portion of the rear frame 8, and is grounded to the ground in a state where the front frame 1 and the rear frame 8 are folded, and becomes a leg portion on the front side of the rear frame 8 in a folded state. In use, it is configured to have a sufficient distance from the ground.
前記脚部１５は使用状態で地面に対して十分な間隔を有するように形成されているため、回動軸１４と前車輪軸３との距離Ａが回動軸１４と後車輪軸９との距離Ｂより短く形成した構成では、リンク機構１３の回動軸１４を使用状態で地面に対して垂直な構成とした場合、折りたたみ状態で前後車輪４、１０及び脚部１５の３点で起立させた際には、車体が音フレーム８側に傾斜した状態となり、安定性が悪くなる。 Since the leg portion 15 is formed so as to have a sufficient distance from the ground in use, the distance A between the rotation shaft 14 and the front wheel shaft 3 is the distance between the rotation shaft 14 and the rear wheel shaft 9. In the configuration formed shorter than the distance B, when the rotation shaft 14 of the link mechanism 13 is configured to be perpendicular to the ground in use, the link mechanism 13 is erected at the three points of the front and rear wheels 4 and 10 and the leg 15 in the folded state. In this case, the vehicle body is inclined toward the sound frame 8 and the stability is deteriorated.
そこで、本実施形態では、前記リンク機構１３の回動軸１４を、上方になる従って前方に位置するように前後方向に傾斜させている。前記回動軸１４を前方側に傾斜させることにより、折りたたみ状態で前記前後車輪４、１０及び脚部１５の３点できるさせた際、車体が地面に対して略垂直な状態に起立させることができる。尚、前記回動軸１４の傾斜角度は、前記回動軸１４から前車輪軸３との距離Ａ、前記回動軸１４と後車輪軸９との距離Ｂ、前記距離Ａと距離Ｂとの差、前記脚部１５の地面からの距離などの各種寸法等により異なるが、本実施形態では、使用状態における垂直軸に対して約１度前方に傾斜させている。 Therefore, in the present embodiment, the rotation shaft 14 of the link mechanism 13 is inclined in the front-rear direction so as to be positioned upward and thus forward. By tilting the rotating shaft 14 forward, when the three points of the front and rear wheels 4, 10 and the leg 15 can be made in a folded state, the vehicle body can stand up in a state substantially perpendicular to the ground. it can. The tilt angle of the pivot shaft 14 is determined by the distance A between the pivot shaft 14 and the front wheel shaft 3, the distance B between the pivot shaft 14 and the rear wheel shaft 9, and the distance A and the distance B. Although this differs depending on the difference and various dimensions such as the distance of the leg 15 from the ground, in this embodiment, the leg 15 is inclined forward by about 1 degree with respect to the vertical axis in use.
前記後フレーム７の前部寄りの位置には、シートパイプ１２の下方位置に、左右方向にクランクシャフト１６が回動可能に設けられ、このクランクシャフト１６に取り付けられた図示しないフロントスプロケットと後車輪軸９に取り付けられた図示しないリヤスプロケットとの間にチェーン１７が掛けられている。前記クランクシャフト１６の両端にはクランク１８が設けられ、該クランク１８にはペダル１９が設けられている。前記クランクシャフト１６、フロントスプロケット、リヤスプロケット、チェーン１７、クランク１８及びペダル１９により人力駆動系の人力駆動部を構成している。 A crankshaft 16 is provided at a position near the front portion of the rear frame 7 so as to be rotatable in the left-right direction at a position below the seat pipe 12, and a front sprocket and a rear wheel (not shown) attached to the crankshaft 16 are provided. A chain 17 is hung between a rear sprocket (not shown) attached to the shaft 9. A crank 18 is provided at both ends of the crankshaft 16, and a pedal 19 is provided on the crank 18. The crankshaft 16, the front sprocket, the rear sprocket, the chain 17, the crank 18 and the pedal 19 constitute a human power drive unit of a human power drive system.
２０は前記前車輪４の前車輪軸３に設けられるハブで、内部に電動機及び遊星歯車機構からなる電動機部（いずれも図示せず）を内蔵している。２１は前記シートパイプ１２の後部に着脱自在に装着されるバッテリーで、前記ペダル１９に加わる踏力を検出する踏力検出部の出力に基づいてマイコン等を含む制御部（いずれも図示せず）が前記バッテリー２１の出力により電動機部を駆動するようになっている。前記電動機部、バッテリー２１、踏力検出部及び制御部により前記前車輪４を駆動制御するモータ駆動系の電動駆動部を構成している。 Reference numeral 20 denotes a hub provided on the front wheel shaft 3 of the front wheel 4 and incorporates therein an electric motor unit (not shown) including an electric motor and a planetary gear mechanism. A battery 21 is detachably attached to the rear portion of the seat pipe 12, and a control unit (not shown) including a microcomputer or the like based on the output of the pedal force detection unit that detects the pedal force applied to the pedal 19 The electric motor unit is driven by the output of the battery 21. The electric motor part, the battery 21, the treading force detection part, and the control part constitute an electric drive part of a motor drive system that drives and controls the front wheel 4.
２２は図３に示すように本実施形態の折りたたみ式電動自転車の前記前車輪４の左側に設けられる合成樹脂製のカバー体で、前記前車輪軸３から前車輪軸３近傍の前ホーク２に亘って形成され、前記電動機部への図示しない配線部を保護するようになっている。 As shown in FIG. 3, a synthetic resin cover body 22 is provided on the left side of the front wheel 4 of the folding electric bicycle according to the present embodiment, and extends from the front wheel shaft 3 to the front fork 2 near the front wheel shaft 3. The wiring portion (not shown) to the electric motor portion is protected.
次に、本実施形態の折りたたみ式電動補助自転車の折りたたみ方法について以下に説明する。尚、以下、後フレーム７を移動させず、前フレーム１を後フレーム７に対して回動させるように説明するが、本説明によって本発明を限定するものではない。 Next, the folding method of the folding type battery-assisted bicycle according to this embodiment will be described below. In the following description, the rear frame 7 is not moved and the front frame 1 is rotated with respect to the rear frame 7. However, the present invention is not limited to this description.
リンク機構１３の回動軸１４を支点として、後フレーム８に対して前フレーム１を左方向に回動する。この状態では、図１に示す如く、前フレーム１のカバー体２２は後フレーム８の後車輪軸９よりリンク機構１３側の後車輪軸９に当接しない位置に位置しており、カバー体２２が後車輪軸９への接触により破損することがないと共に、前フレーム１と後フレーム８とで囲まれる空間に位置するので、折りたたみ状態で電動補助自転車が転倒した場合でも、カバー体２２が地面等に接触することはなく、カバー体２２の破損を防止することができる。 The front frame 1 is rotated leftward with respect to the rear frame 8 with the rotation shaft 14 of the link mechanism 13 as a fulcrum. In this state, as shown in FIG. 1, the cover body 22 of the front frame 1 is located at a position that does not contact the rear wheel shaft 9 on the link mechanism 13 side from the rear wheel shaft 9 of the rear frame 8. Is not damaged by contact with the rear wheel axle 9 and is located in a space surrounded by the front frame 1 and the rear frame 8, so that even when the battery-assisted bicycle falls over in the folded state, the cover body 22 remains on the ground. The cover body 22 can be prevented from being damaged.
さらに、この状態で、ハンドルフレーム５を、リンク機構７によりハンドル６が前フレーム１に対して後フレーム８とは反対側に位置するように回動する。カバー体２２は前フレーム１の後フレーム８側に位置しているので、ハンドル６を折りたたんだ状態で移動する際等にハンドル６が動揺してもハンドル６がカバー体２２に接触することはなく、カバー体２２の破損を防止することができる。 Further, in this state, the handle frame 5 is rotated by the link mechanism 7 so that the handle 6 is positioned on the side opposite to the rear frame 8 with respect to the front frame 1. Since the cover body 22 is located on the rear frame 8 side of the front frame 1, the handle 6 does not come into contact with the cover body 22 even when the handle 6 is shaken when the handle 6 is moved in a folded state. Further, it is possible to prevent the cover body 22 from being damaged.
電動補助自転車を折りたたんだ状態では、前後フレーム１、８及び折りたたんだハンドルフレーム５を図示しないベルト等により締結する、或いは、収納袋に収納し、折りたたんだ状態において電動補助自転車の前後のフレーム１、８及びハンドル６が回動するのを阻止することが運搬上、或いは収納上好ましい。 In the folded state of the battery-assisted bicycle, the front and rear frames 1 and 8 and the folded handle frame 5 are fastened by a belt (not shown) or the like, or stored in a storage bag and folded in the folded state. It is preferable in terms of transportation or storage that the 8 and the handle 6 are prevented from rotating.
折りたたんだ状態では、前後車輪４、１０及び脚部１５が接地して起立状態に保持される。重量物である電動機部とバッテリー２１は、それぞれ前車輪４のハブ２０内、シートパイプ１２の後方位置に配置され、前フレーム１と後フレーム８に分散配置されるので、図１に示すように折りたたんだ状態を上方から見て、前フレーム１方向及び後フレーム８方向（前後フレーム１、８の鉛直線方向に対して交差する方向）に安定して起立状態を保持することができる。 In the folded state, the front and rear wheels 4, 10 and the leg 15 are grounded and held in an upright state. As shown in FIG. 1, the heavy-duty electric motor unit and the battery 21 are respectively disposed in the hub 20 of the front wheel 4 and the rear position of the seat pipe 12 and are distributed in the front frame 1 and the rear frame 8. When the folded state is viewed from above, the standing state can be stably maintained in the direction of the front frame 1 and the direction of the rear frame 8 (direction intersecting the vertical direction of the front and rear frames 1 and 8).
また、バッテリー２１は、後フレーム８の後車輪軸９よりも前方側に位置するので、脚部１５側に加重が加わり、重量物である電動機部とバッテリー２１の荷重は、折りたたんだ状態で接地する前後車輪１、１０側と脚部１５側に分散され、リンク機構１３側が浮き上がる方向に対しても安定して起立状態を保持することができると共に、脚部１５に加わる荷重を軽減させて不必要に脚部１５の強度を向上させる必要をなくすことができる。 Further, since the battery 21 is located on the front side of the rear wheel shaft 9 of the rear frame 8, a load is applied to the leg portion 15 side, and the load of the heavy electric motor portion and the battery 21 is grounded in a folded state. The front and rear wheels 1, 10 and the leg 15 side are dispersed, and the link mechanism 13 side can be stably kept upright even in the direction in which the link mechanism 13 is lifted. The need to improve the strength of the leg portion 15 can be eliminated.
尚、上記実施例においては、リンク機構１３の回動軸１４と前車輪軸３との間の距離Ａと、回動軸１４と後車輪軸９との間の距離Ｂとの関係が、Ａ＜Ｂとなるように構成し、後車輪軸９が前車輪１のカバー体２２に接触しないように構成したが、Ａ＞Ｂに設定して同様の課題を達成する構成としてもよい。また、前車輪４の直径を後車輪１０の直径より大きく形成し、或いは、前車輪４の直径を後車輪１０の直径より小さく形成して、前車輪４のカバー体２２が後車輪軸９に接触しないように構成してもよい。 In the above embodiment, the relationship between the distance A between the rotation shaft 14 of the link mechanism 13 and the front wheel shaft 3 and the distance B between the rotation shaft 14 and the rear wheel shaft 9 is A Although it comprised so that it might become <B and the rear-wheel axle 9 did not contact the cover body 22 of the front wheel 1, it is good also as a structure which sets to A> B and achieves the same subject. Further, the diameter of the front wheel 4 is formed larger than the diameter of the rear wheel 10, or the diameter of the front wheel 4 is formed smaller than the diameter of the rear wheel 10, and the cover body 22 of the front wheel 4 is attached to the rear wheel shaft 9. You may comprise so that it may not contact.
