[0032] 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。
[0033] 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。
[0034] 另一实施例： 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贴合。
[0035] 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。
[0036] 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
[0037] 解决折叠车架减振问题方案的实施例为： 所述斜撑连杆 6由内套管 11和外套管 1 2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 11和外套管 12的外端部设置转轴 17， 内套管 11和外套管 1 2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。
[0038] 解决折叠车架减振问题方案的另一实施例为： 内套管 11套接在外套管内的端部 放大， 外套管 12与之配合的端部相应收紧， 弹簧设置于外套管 12内并与内套管 1 1相顶， 当驾驶人乘坐于座椅上吋， 弹簧收缩， 上部的套管向下运动， 弹簧的收 缩距离同吋构成行程限位。
[0039] 为了实现联动锁定与解锁， 一个解锁幵关 15可以同吋实现底盘 5与其他折叠关 节的解锁与锁定， 其他折叠关节可以设置锁定结构， 拉线 14增设分节连接解锁 弹销即可实现。
[0040] 进一步的， 为防止踩踏操纵端 21吋发生卡死现象， 为解锁顶片 23设置行程限位 ， 解锁顶片 23设有轴套， 底盘设有与轴套配合的轴， 该轴固定于底盘 5， 解锁顶 片 23通过该轴转动连接于底盘 5， 所述轴套设置飞翅 28 ; 链臂设置凹弧， 以为解 锁顶片 23留足运动空间。 踩下操纵端 21吋， 当飞翅 28运动到底盘 5底面并顶住吋 ， 解锁顶片 23无法继续向下运动， 实现行程限位， 然后继续进行车架折叠， 不 会产生阻隔。
[0041] 为解锁顶片 23设置行程限位的另一实施例： 解锁顶片 23设有轴套， 底盘设有与 轴套配合的轴， 该轴固定于底盘 5， 解锁顶片 23轴接于底盘 5 ; 所述底盘在操纵 端 21运动的一侧设置固定凸点 29。 踩下或按下操纵端 21吋， 当操纵端 21运动到 底盘 5侧面的固定凸点 29并被阻隔顶住吋， 解锁顶片 23无法继续向下运动， 实现 行程限位， 解锁后继续进行车架折叠。
[0042] 需要指出的是， 上述实施方式仅是本发明优选的实施例， 对于本技术领域的普 通技术人员来说， 在符合本发明工作原理的前提下， 任何等同或相似的替换均 落入本发明的保护范围。
