解锁手柄2设置复位弹簧。
本方案电动折叠车包括车把架1、踏板15、座杆17与轮架18， 车把架 1 设置轮盖 7 ，轮盖 7 与转向支架 13 轴连接， 座杆 17 轴连接于踏板 15 ，轮架 18 与踏板 15 轴连接，轮架轴套 10 穿过连接轴。 折叠完成后，车把架1、座杆17、踏板15、轮架18两两相贴，座杆17、踏板15、轮架18依次排列于车把架1的轮廓空间内 ，车辆折叠后外观呈闭合甲壳状。
车辆由展开状态折叠时， 翻动解锁手柄2，牵引线3在解锁手柄2作用下拉动锁柱4、座杆锁舌5和横销6，锁柱4由轮盖7的斜槽一8内脱出，车把架1与踏板15解锁；座杆锁舌5脱离座杆17，座杆17解锁；横销6脱离轮架轴套10，轮架18与踏板17解锁，一只解锁手柄同时控制三套锁定结构。
第一支分支线作用下，锁柱4由斜槽一8内脱出，轮盖7与转向支架13间的锁定被解锁，即车把架1与踏板15解锁，能够进行踏板15的折叠；第二支分支线作用下，座杆锁舌5被向下拖动，使其脱离座杆17，座杆17与踏板15间的锁定解锁，能够进行座杆17的折叠；第三支分支线作用下，横销6从轮架轴套10的销孔一11中脱出，踏板15与轮架轴套10之间的锁定解锁，因轮架轴套10与轮架18为一体设置，即踏板15与轮架18解锁，能够进行轮架18的折叠。
将踏板15向着车把架1的方向向上合并，轮架18向着踏板15底面的方向向下合并，由于转向支架13与轮盖7之间设有转轴，转向支架13能够以转轴为轴心向上运动，转向支架13带动踏板15一起向着车把架1的方向合并，同时 座杆 17 随踏板15一起向上运动，由于轮盖7为圆形，转向支架13向上运动过程中，锁柱4得以沿轮盖7的边缘向上做弧形运动；随 着轮架轴套 10 的顺时针方向转动， 轮架18向着踏板15的底面翻折，直至车把架1、座杆17、踏板15、轮架18四者两两相互闭合；此时锁柱4刚好运行至轮盖7的第二个斜槽处，在弹簧作用下，锁柱4被推入斜槽内，完成转向支架13与轮盖7的锁定，即车把架1与踏板15锁定 ；座杆锁舌 5 在弹簧作用下抵于座杆 17 的底端，弹簧处于被迫压缩状态，座杆 17 被座杆锁舌 5 顶住；轮架轴套 10 设置的销孔二 23 转动至横销 6 位置处，横销 6 在弹簧作用下，自动弹入 销孔二 23 中，轮架轴套 10 无法继续转动。车架整体折叠完成，车把架 1 与 踏板15被锁定，座杆17被锁定；踏板15与轮架18被锁定，车架各部分不会因 自重从折叠状态放开。
座杆锁舌5设置基座22，基座22与踏板15通过转轴连接，第二支分支线穿过定位片与基座22相连，基座22的两个支臂之间设置倾斜夹角，连接分支线的支臂长度小于连接座杆锁舌5的支臂长度，当分支线水平拉动基座22的一个支臂时，另一支臂向下运动，带动座杆锁舌5脱离座杆，而且，连接分支线端活动较小距离时座杆锁舌5可以得到较大的活动距离 。
车辆由折叠状态展开时，再次翻动解锁手柄 2 ， 锁柱4由斜槽二9内脱出，车把架1与踏板15间的锁定解锁，座杆锁舌5向下运动，脱离座杆17，座杆17得以转动，横销6从销孔二23中脱出，踏板15与轮架18间的锁定解锁。
将轮架 18 与踏板 15 向着地面翻折，再将 座杆 17 向着踏板 15 翻折， 转向支架13以转轴为轴心向下运动，锁柱4回到斜槽一8处，锁柱4被弹簧自动弹入斜槽一8内，转向支架13展开并被锁定；同时， 随着轮架轴套 10 的逆时针方向转动，销孔一 11 转动至横销 6 位置处，在弹簧作用下，橫销 6 自动弹入销孔一 11 中，轮架 18 被展开锁定， 车轮着地 ；随着座杆向踏板15的翻折， 座杆锁舌5在弹簧作用下自动复位至座杆17与踏板15之间的空隙中， 完成对座杆 17 的锁定。车架整体伸展完成， 操作者可以坐在鞍座上骑行 。
为了锁定稳定，本方案第一支分支线增设分支器连接两个锁柱，相应的两个轮盖边缘分别设置两个斜槽。
所述牵引线3串接多个分支器，通过分支器分别连接多个锁销，所述锁销对应于不同节点的旋转折叠部位，所述旋转折叠部位分别设置相应的锁孔，各分支线通过分支器汇集于解锁手柄2，从而实现解锁手柄2对多个折叠节点的解锁与锁定的操控。
需要指出的是，上述实施方式仅是本实用新型优选的实施例，对于本技术领域的普通技术人员来说，在符合本实用新型工作原理的前提下，任何等同或相似的替换均落入本实用新型的保护范围。
