具体实施方式：
如图 所示， 一种电动折叠车座管的锁定装置，包括座管 2 、踏板 3 与联动支架 7 ，其特征在于：所述踏板 3 与联动支架 7 通过主轴 8 转动连接，座管 2 通过转轴 15 与踏板 3 转动连接，其末端穿入踏板壳，联动支架 7 固定设置凸起挡块 4 ，座管 2 末端相应的设置凹孔 5 ，所述联动支架 7 设置带有锁钩 20 的锁臂，座管 2 末端后部相应的设置钩槽； 所述锁臂 19 一侧 对应向上的顶杆 13 ，顶杆 13 上穿踏板 3 设置踩踏点 14 ； 踏板 3 与踩踏点 14 之间设置复位弹簧 21 ，所述锁臂 19 前端 与联动支架 7 轴连接； 所述联动支架 7 与锁臂 19 之间设置弹簧 18 ，弹簧 18 向上弹顶锁臂 19 ； 所述锁臂 19 一侧 与顶杆 13 互顶， 所述顶杆 13 设置在座管 2 的一侧 ； 所述顶杆 13 设置卡簧 12 ；所述踏板 3 设置高于踏板平面的弧形支臂 16 ，所述转轴 15 设置于支臂 16 中端。
顶杆 13 设置环形凹槽，环形凹槽设置卡簧 12 ，顶杆 13 和锁臂 19 可以分体设置，卡簧 12 设置在踏板 3 下面，防止顶杆 13 从踏板 3 中抽出，特别是踏下踩踏点 14 松开时防止其被复位弹簧 21 弹出。
顶杆 13 设置固定座，受固定座约束只能上下运动，防止左右摇摆，固定座设置于踏板 3 内部。
本案锁臂 19 下设弹簧 18 可以替换为弹性锁臂。
本案取顶杆 13 与锁臂 19 的夹角在展开状态时为 90 度，可以缩短顶杆 13 的长度，踩踏用力方便；这个角度使得踩踏点 14 在座管 2 的一侧 ，二者在左右方向上并排设置着，顶杆 13 垂直向上传出踏板 3 ，操作者的两腿是夹持座管 2 的，其落脚点正好轻松落在踩踏点 14 上。如果踩踏点 14 位置比此靠前或靠后，顶杆 13 成为倾斜的斜杆，踩踏会比较吃力，不方便也不好用。踩踏点 14 的位置设置在本案中也不会影响座管 2 的翻折。
电动折叠车还包括 车把架 1 ，它与踏板 3 通过联动支架 7 轴连接，二者可以折叠闭合在一起，车把架 1 设置前轮支架 6 ，前轮支架 6 设置车轮，联动支架 7 开设轴孔，主轴 8 穿过轴孔。
主轴 8 设置成方形轴端，轴孔相应设置为方形，主轴 8 与踏板 3 固定连接在一起，踏板 3 翻折过程中，主轴 8 跟随踏板 3 一起运动。
凹孔 5 留有座管 2 折叠的活动行程，不会妨碍座管 2 的翻折。
主轴 8 的中段设置两个相邻的侧切面 9 ，两个侧切面 9 之间可以取 90 °夹角，需要说明的是其夹角设置取决于张开时踏板 3 与车把架 1 的角度， 90 °夹角是经实验证明的优选方案，驾驶者可以保持舒服轻松的姿势握持车把架 1 。
联动支架 7 内设置定位片 10 与弹性胶块 11 ，弹性胶块 11 设置于定位片 10 的里面。
侧切面 9 和定位片 10 相配合，主要实现踏板 3 与车把架 1 的相对固定。侧切面 9 与定位片 10 贴合时，主轴 8 转动遇到限制，更大的外力作用下，主轴 8 克服转动限制，另一个侧切面自动向定位片 10 贴合，再次实现相对固定。需要打破这种相对固定时，只需更大的外力参与进来即可。本案中，主要解决展开和合并时，车把架 1 和踏板 3 的相对固定，不至于一旦撤销外力就发生状态形变。
座管 2 与踏板 3 通过转轴 15 相连接，座管 2 相对于踏板 3 能够实现垂直方向的拉开与闭合。
车把架 1 内设置电池， 电池被隐藏，不影响车辆体积与外观，结构稳定可靠，存放安全。
为了保证电池的使用寿命及安全，电池可以采用多节锂电池构成的锂电池组， 锂电池较普通铅酸电池来说，具有使用寿命长、高效、安全、环保等优点。
座管 2 设置鞍座 17 ，鞍座 17 尾端开设扁孔，形成一抓握部，车辆折叠后，抓握部在上，车轮在下，手拉抓握部即可拉动车辆前行，无论是远距离移动车辆或是带动车辆上下楼梯都十分方便，省时省力。
为保证装配精度与强度稳定可靠， 座管 2 与鞍座 17 在制作时，通过模具工艺一体成型。
车辆骑行状态下，车轮着地，座管 2 与踏板 3 之 间约成 45 °角，座管2与车把架1之间约成45°角，踏板3与车把架1之间约成90°角。
展开状态，联动支架7的凸起挡块4探入座管2的凹孔5内部，凸起挡块4阻挡座管2鞍座端继续向下运动，锁钩20进入钩槽内，弹簧18从下面顶住锁臂19，座管2被锁定，驾驶者可以坐在鞍座17上操控车辆。
车辆折叠时，第一步， 按压踩踏点14，在踏板3和踩踏点14之间设置的复位弹簧21发生收缩形变，锁臂19在顶杆13作用下下移，锁钩20从钩槽内脱出， 操作者握住座管2向着车把架 1 的方向合并，座管 2 以转轴 15 为轴心，座 管 2 的 末端 受到转 轴 15 的 约束相应的向后运动， 凹孔5与凸起挡块4分离 。松开 踩踏点14，因为在踏板3和踩踏点14之间设置了复位弹簧21，踩踏点14可以自动复位。
第二步， 将 踏板 3 向着车把架1的方向合并， 座管 2 随踏板3一起向上运动，此时主轴8的第一个侧切面在外力作用下向上运动，脱离定位片10，直至车把架1、座管2、踏板3三者两两相互闭合，随着主轴8的转动 第二个侧切面自动与定位片 10 相贴合，第一个侧切面位于第二个侧切面的右侧，主轴 8 再次被定位片 10 锁定，防止踏板 3 因自重从折叠状态放开。
车辆 从折叠状态 展开时， 先 进行踏板 3 的伸展， 将踏板 3 向着地面翻折，主轴 8 被迫发生转动，压迫定位片 10 ，弹性胶块 11 发生压缩形变，第二个侧切面脱离定位片 10 ，第一个侧切面自动向着定位片 10 贴合； 将座管 2 向着踏板 3 翻折，随着 鞍座 17 向下运动，座管 2 末端向上翻挑 ， 直至其凹孔 5 套入凸起挡块 4 内，鞍座 17 无法继续向下运动，此时锁钩 20 自动进入钩槽，弹簧 18 被进一步压缩，鞍座 17 也无法向上回转，座管 2 被固定。 操作者可以坐在鞍座 17 上骑行。
前轮支架 6 连接转向轴，车把架 1 带动前轮实现转向。
为保持车辆的外观简洁及减轻重量，本方案座管2采用单杆式结构，为保证其强度，座管2与鞍座 17 采用碳纤维材料制成，碳纤维材料具有比重轻、强度大等优点， 应用于民用、军用、建筑、航天以及超级跑车领域。
