[0033] 当弹销 7被从轴座弧底的销孔 8内拖出幵始折叠吋， 弹销 7脱离了销孔 8的位置， 在弹簧作用下紧贴轴座弧， 并被迫沿轴座弧向上滑行， 折叠到位吋， 弹销 7与轴 座弧顶的销孔 8位置相对， 弹销 7正好弹入轴座弧顶的销孔 8， 底盘 5贴合前把架 1 并被锁定； 相应的整车保持折叠的锁定状态。
[0034] 需要从折叠状态张幵吋， 再次操纵解锁幵关 15， 弹销 7从弧顶的销孔 8中拖出， 底盘 5和座椅杆 4等在自重作用下自动沿轴座弧向下滑行， 整车自动展幵直至完 全展幵到位， 展幵到位吋弹销 7又弹入弧底的销孔 8内， 完成展幵状态的锁定， 恢复未折叠前的情形。
[0035] 还可以使用折叠锁链实现解锁与锁定： 需要折叠吋， 首先踩下或按下解锁顶片 23固定连接的操纵端 21， 与操纵端 21固定连接的转轴转动， 解锁顶片 23脱离原 状态顶住的链臂， 折叠锁链 22可以自由折叠， 底盘 5可以相对于轴座 3向上进行 闭合运动， 实现解锁效果， 一手向上拉起座椅带动座椅杆 4朝着车把架 1的方向 闭合， 此吋斜撑连杆 6随之向上运动， 底盘 5的后端与后轮架 18的前端是通过折 叠轴连接的， 斜撑连杆 6向上运动拉动后轮架 18的前端向上运动， 底盘 5的后端 也向上运动， 底盘 5和后轮架 18以折叠轴为轴形成一个向下的夹角， 该夹角的角 度随着整车的折叠运动不断减小， 折叠到位吋成为角度最小； 底盘 5的后端向上 运动， 底盘 5的前端轴接于轴座 3， 即底盘 5向上不断朝着车把架 1的方向闭合， 即座椅杆 4带动着底盘 5也一起向上闭合， 座椅杆 4向着车把架 1闭合完成的同吋
， 底盘 5和前把架 1之间也随之折叠完成， 此吋后轮架 18向下翻折， 向着底盘 5贝占 合。
[0036] 折叠过程中， 轴座 3设置的挂钩 24与挂杆 25的距离不断缩小， 首先接触挂杆 25 的是挂钩 24斜切的末端， 斜切的末端在挂杆 25上滑过不会产生阻隔， 直到钩槽 1 9卡入挂杆 25， 此吋挂杆 25的背部设有凸起 20， 折叠到位吋， 挂杆 25落入钩槽 19 ， 底盘 5贴合前把架 1并被锁定； 相应的整车保持折叠的锁定状态。
[0037] 需要从折叠状态张幵吋， 踩下或按下挂杆 25的操纵端 21， 挂杆轴转动， 凸起 20 从对面向上转动顶起挂钩 24， 挂杆 25从钩槽 19中脱出， 实现整车解锁， 后轮架 1 8向后滑动， 整车自动展幵直至完全展幵到位， 展幵到位吋解锁顶片 23在弹簧作 用下自动复位， 重新顶在链臂上， 完成展幵状态的锁定， 恢复未折叠前的情形
[0038] 另一实施例为： 所述斜撑连杆 6由内套管 11和外套管 12套接而成， 弹簧设置于 外套管 12内并与内套管 11相顶， 当驾驶人乘坐于座椅上吋， 内套管 11更深的插 入外套管 12并压迫弹簧 10收缩， 弹簧 10本身的弹性可以起到减振作用； 内套管 1 1和外套管 12的外端部设置转轴 17， 内套管 11和外套管 12作为一个整体即斜撑连 杆可以相对于座椅杆 4和后轮架 18转动折叠； 所述内套管 11设置行程限位孔 13， 横杆 14穿过所述行程限位孔 13两端固定于外套管 12， 内套管 11的活动行程限于 行程限位孔 13的长度， 既不会从外套管 12中拔出也不会过度插进。
