[0024] 接近开关无需与运动部件进行机械直接接触，当物体接近开关的感应面到动作距离时，接近开关即给控制器提供控制指令。
[0025] 接近开关具有传感性能，且动作可靠，性能稳定，频率响应快，应用寿命长，抗干扰能力强等、并具有防水、防震、耐腐蚀等特点。

[0027] 电机 1 设置电源开关 24 ，按下电源开关 24 电机开始工作，同时控制踏板 14 、座杆 28 、轮架 16 三套装置的锁定与解锁，保证车辆在骑行状态或闭合状态下结构稳定，折叠关节处不会自动打开，提高使用安全性能，并能够省去繁琐的快拆配件及拆装工序，操作简单，省时省力。
[0028] 为了方便操作及外观美观，电源开关 24 设置于车把架 15 的外壳上。
[0029] 牵引线 4 设置分支器 25 ，分支器 25 分出三条分支线，三条分支线分别连接弹性锁柱 5 、座杆锁舌 6 和橫销 7 。设置分支器能够实现线路数量的优化配置，避免线路拐弯打折，操控解锁手柄能够同时控制牵引线及分支线下分出的结构。
[0030] 锁柱 5 与定位柱 26 之间设置弹簧，定位柱 26 固定于转向支架 27 ，分支线穿过定位柱 26 与锁柱 5 相连。
[0031] 转向支架 27 设置锁柱 5 的活动行程，锁柱 5 用于锁定车把架 15 与踏板 14 。转向支架 27 设置锁柱 5 的活动行程，用以限制锁柱 5 的移动距离，避免锁柱 5 移动距离过大，还能规范锁柱 5 的运动，避免其跑偏。
[0032] 锁柱 5 受外力脱出，回位时，弹簧起到助力作用。
[0033] 分支线增设分支器从两端连接横销 7 。本方案中，第三条分支线增设分支器，分支为两条子分支线，在对应横销 7 的两端，踏板 14 设有定位片，两片定位片与横销 7 之间设置弹簧，两支子分支线分别穿过两片定位片连接横销 7 的两端。

[0035] 电机 1 可以设置杠杆器与牵引线 4 相连。应用杠杆原理，按动电源开关 24 ，电机 1 可以轻松拉动牵引线 4 ，锁定和解锁时较为省电。
[0036] 本方案感应点可以设置为磁铁或电磁铁，通过电磁感应控制电机工作，磁场均强，灵敏高效。

[0040] 将踏板 14 向着车把架 15 的方向向上合并，轮架 16 向着踏板 14 底面的方向向下合并，由于转向支架 27 与轮盖 8 之间设有转轴，转向支架 27 能够以转轴为轴心向上运动，转向支架 27 带动踏板 14 一起向着车把架 15 的方向合并，同时座杆 28 随踏板 14 一起向上运动。
[0041] 车架闭合后，车把架 15 与踏板 14 相闭合，第一感应点 33 与第一传感器 30 配合产生感应，生成相应信号并传输给电机控制器；同时，踏板 14 与轮架 16 闭合，轮架 16 翻折于踏板 14 的底面，第三感应点 35 与第三传感器 32 配合产生感应，生成相应信号同时传输给电机控制器，在该两组信号控制下，电机控制器控制电机 1 开始运转，曲轴 3 进入下半圈运动，套筒 22 向左平移，牵引线 4 被收回。
[0042] 曲轴 3 完成下半圈运动时，近端接近开关 17 产生感应发出相应信号给电机控制器，电机控制器控制电机 1 停止运转。此时套筒 22 在固定架内向左平移，将牵引线 4 收回，在弹簧作用下，锁柱 5 被推入斜槽二 10 内，转向支架 27 与轮盖 8 锁定，即车把架 15 与踏板 14 锁定；座杆锁舌 6 在弹簧作用下抵于座杆 28 的底端，弹簧处于被迫压缩状态，座杆 28 被座杆锁舌 6 顶住，座杆 28 被锁定；轮架轴套 11 设置的销孔二 13 转动至横销 7 位置处，在弹簧作用下，横销 7 被弹入销孔二 13 中，轮架轴套 11 无法继续转动，轮架 16 与踏板 14 锁定。车架整体折叠完成，车把架 15 与踏板 14 被锁定，座杆 28 被锁定；踏板 14 与轮架 16 被锁定，车架各部分不会因自重从折叠状态放开。
[0043] 车辆由折叠状态展开时，按动电源开关 24 ，电机 1 工作，曲轴 3 进行上半圈圆周运动中，套筒 22 向右平移。
[0044] 曲轴 3 完成上半圈运动时，曲轴 3 靠近远端接近开关 18 ，电机 1 停止运转。此时套筒 22 在固定架内向右平移，将牵引线 4 拉出，牵引线 4 拉动锁柱 5 、座杆锁舌 6 和横销 7 ，锁柱 5 由轮盖 8 的斜槽一 9 内脱出，车把架 15 与踏板 14 解锁；座杆锁舌 6 脱离座杆 28 ，座杆 28 解锁；横销 7 脱离轮架轴套 11 ，轮架 16 与踏板 14 解锁。
