Abstract
Description
1-1.電動自転車の全体構造
図1に示す一実施形態の電動自転車1は、電動アシスト自転車である。一実施形態の電動自転車1は、フレーム10と、フレーム10に回転可能に連結された二つの車輪11と、フレーム10に取り付けられたハンドル部12、サドル部13、及びモーターユニット15とを備える。二つの車輪11は、前輪111と後輪112である。このうち後輪112が、モーターユニット15から出力される駆動力によって回転駆動される。
図2、図3、図8、図14等に示すように、バッテリー2の主体を構成するバッテリー本体3は、複数の蓄電池セル31と、これら複数の蓄電池セル31を囲む筒型のケース32と、ケース32の外表面に取り付けられたカバー33と、ケース32の下端を覆う底カバー35とを備える。カバー33は、ケース32の外表面に取り付けられた状態で、バッテリー2の表面の一部を構成する。
次に、バッテリー2の上端部を構成する保持装置4について、図8-図11等に基づいて説明する。保持装置4は、電動自転車1のフレーム10に固定されたロック装置6に対して、バッテリー本体3を着脱可能に保持するために用いられる。
ロック装置6は、フレーム10に固定されるロックユニット5の主体を構成する装置であり、図5等に示すように、バッテリー2の一部を構成する保持装置4を、着脱可能に固定することができる。一実施形態の電動自転車1においては、保持装置4とロック装置6とで、バッテリー2をフレーム10に保持させるためのバッテリー保持機構8が構成される。
固定構造7は、ロック装置6と組み合わさってロックユニット5を構成する構造であって、ロック装置6を、フレーム10の切り欠き部分108の長手方向の端部(具体的には切り欠き部分108の上端部)に固定する機能を有する。切り欠き部分108の長手方向は、フレーム10のうちバッテリー2が装着される部分(つまりダウンチューブ103)の長手方向と一致する。
上記の構成を備える一実施形態の電動自転車1では、利用者のキー操作に基づいたメインロック機能と、操作レバー43を利用したサブロック機能の両方を利用して、バッテリー2をフレーム10に対して二重固定することができる。利用者は、例えばバッテリー2を片手で掴んだ状態のまま、操作レバー43を簡単に押し込み操作することができる。
一実施形態の電動自転車1が備える各構成は、いずれも一例に過ぎず、同様の作用効果を奏する範囲内において適宜変形を施すことが可能である。
