Description

拉杆箱式快速折叠微型电动车 技术领域
本发明属于代步工具领域，进一步涉及一种可折叠的电动车，具体涉及一种拉杆箱式快速折叠微型电动车。
背景技术
本发明人在2013年申请的公告号为CN103204209B的专利中公开了一种有折椅功能的拉杆箱式便携折叠电动三轮车，利用折叠车架的翻转可以将车前轮和控制车把收纳至坐框基座的下方，然后通过其他的一些辅助结构可以实现在电动三轮车、拉杆箱和座椅三种状态下转换。
但是在实际使用过程中发现，其存在以下缺陷：由于主要的连接部件折叠车架的上方和下方分别连接有控制车把和车前轮，且为了保证车前轮和控制车把能够收纳进坐框基座的下方，从而使得折叠车架距离地面有一定的高度，这样就导致用户在使用电动三轮车的时候，需要抬腿跨过折叠车架才能坐到坐框基座上，而且在行驶过程中用户的脚只能放在前轮两侧的折叠踏板上，对于年纪比较大或者腿脚不利索的残障人士来说，不仅使用不便，还存在安全隐患。

本发明的工作过程如下：
初始状态如图1所示，此时用户可以直接乘坐，利用控制车把对电动车进行控制，用户上车时不需要抬腿，安全系数高；
当不需要乘坐时，对照图1、图9和图10，首先用左手大拇指按压矩形限位片，将509以7为圆心逆时针转动(按图1的视角方向)，此时509与510紧靠在一起；参照图7和图8，然后右手捏一下操作把手，拉动507的上端向右移动直至505根508脱开，此时左手带动510和509以501为圆心一起顺时针转动，从而使509和510均紧贴在脚踏板402上；继续参照图1，再然后将509、510和402整体一起以3为圆心逆时针转动，将509、510和402一起收纳至1的下方(需要注意的是，将6对准104放入，防止车轮摆动)；最后利用102卡住402，103卡住7，此时的状态如图11所示，完成整个电动车的折叠；
参照14，由于此时103卡住的是7上的712(图14中712被103挡住了)，509是被1挡住了，此时509不能顺时针转动；若需要拖动电动车，首先需要解除103的限制，将7向外拖动至708被103限制，此时的状态如图15所示；然后逆时针转动509，进而带动7向上转动，直至509被709顶住如图16所示，此时整个电动车的状态如图17所示， 用户可以直接手握操作把手拖动电动车行进。
综上，仅为本发明之较佳实施例，不以此限定本发明的保护范围，凡依本发明专利范围及说明书内容所作的等效变化与修饰，皆为本发明专利涵盖的范围之内。
