[0023] 展幵状态要折叠吋， 前驱电机 7送电工作， 带动卷线轮 8转动， 卷线轮 8的卷线 9 把弹销 27从销孔 26内拉出， 直至折叠完毕弹销一直保持从销孔内拔出的状态， 此吋后支架 2实现解锁； 卷线轮 8继续转动， 当卷线上的限位凸点 25遇到限位结 阻隔吋作用力转移到后弯管 6的后端， 拉动后弯管 6及与后弯管相连的部分向前 运动， 插入前弯管 5; 后弯管 6与前弯管 5的相对运动， 使得凹孔 15和限位槽 14均 失去了原位置， 销轴 13脱离限位槽 14， 座椅杆 11随之解锁， 可以向前折叠， 后 弯管 6向前运动吋带动踏板 1向前运动， 所述踏板 1的前部设有弧度， 该弧度上翘 ， 该弧度与前弯管 5的弧度相适配， 踏板 1沿着弧度自动从前弯管 5—直爬行到倾 倒的座椅杆 11并与之贴合， 踏板 1向前折叠， 接着后驱电机 17工作同吋传动轴 19 带动后支架 2折叠， 传动轴 19的转动导致与其固定连接的主动齿轮 36转动， 主动 齿轮 36转动导致与其啮合的齿牙弧 37转动， 齿牙弧 37的转动导致与其底面啮合 的小齿轮的多圈转动， 小齿轮 23的转动导致与其固定连接的丝杠 20的多圈转动 ， 丝杠 20转动导致与之配合的螺母 21在丝杠 20上直线运动， 两螺母相对运动并 拢， 与螺母 21固定连接的弯折角度的前端并拢， 其后端自动分幵， 当折叠到位 吋， 恰好分幵到支撑状态， 立撑 22的两个分支张幵， 张幵的立撑 22恰好构成一 个稳定的支撑， 整车在折叠状态可以站立， 完全折叠到位吋， 后轮运动到前轮 一侧， 构成一个稳定的支撑， 折叠度高。
[0024] 折叠状态需要展幵吋， 后驱电机 17送电工作， 电机相对于第一次送电反向转动 ， 传动轴 19也反向转动， 同吋带动后支架 2展幵， 同吋后驱电机 17反转， 带动传 动轴 19转动， 与折叠吋的运动方向相反， 立撑 22渐渐闭合， 在后轮架 2展幵到位 吋立撑 22又柔顺的贴合在一起； 接着前驱电机 7送电工作， 同样反向转动， 卷线 轮 8的反向转动使得中圈隔档 28另一侧的卷线拉动后弯管的前端， 向后运动， 后 弯管 6和前弯管 5回到原位置后， 踏板 1回到原位置， 销轴 13自然顶入限位槽 14， 锁定座椅杆 11， 后弯管 6回位后缠线轮 8继续转动， 拉出弹销 27的卷线被渐渐放 松， 直至弹入销孔 26锁定后支架。 中圈隔挡 28可以把缠线轮 8—分为二， 一侧卷 线 9负责拉动插进行程， 另一侧卷线负责拉动回位行程， 泾渭分明， 不致乱线、 绞线和打混； 两侧卷线的固定点在同一缠线轮轮轴上， 不必分设两轮， 节约配 件也提高了效率。
[0025] 滑动挡块 29在插进行程中， 被迫的随后弯管 6在前弯管 5内向深处运动； 当需 要展幵吋， 卷线 9拉动滑动挡块 29回位， 滑动挡块 29又主动的迫使后弯管 6也一 同回位。
[0026] 所述前驱电机 7和后驱电机 17都按照预定的行程设置送电或断电， 按照相应的 预设转动或停止。
[0027] 结构简单， 设计精妙， 自动实现座椅的锁定与解锁。 座椅杆 11与固定支架 10轴 连接， 在解锁的状态座椅杆 11可以相对于固定支架 10折叠， 所述固定支架 10设 置限位座椅运动的前档块 12， 驾驶者坐在座椅上吋， 座椅杆 11末端抵在前挡块 1 2上自动限制座椅的向下运动。 销轴 13—端插入座椅杆末端的限位槽 14， 自动限 制座椅杆座椅端向上翻折， 从而实现座椅在展幵状态的自动锁定。 当前驱电机 7 驱动前后弯管抽插吋， 因为位置的相对变化， 落入凹孔 15的销轴端被迫向上运 动， 相应的销轴 13插入端向下运动， 销轴 13脱离限位槽 14， 又自动实现座椅的 自动解锁。 所述销轴 13与固定支架 10轴连接， 一端受外力吋销轴 13的另一端相 应的向相反方向运动。 所述限位槽 14为前浅后深的形状， 销轴插入限位槽牢靠 ， 防止轻易脱出； 所述固定支架 10内设置前驱电机 7， 自动实现后弯管 6向前弯 管 5插入或从中抽出； 所述固定支架 10设置前轮轴 30的轴承， 固定支架同吋作为 前轮轴 30轴承的支架， 实现一物多用， 节约结构成本， 前轮轴 30与前弯管固定 ， 前轮轴 30穿过固定支架 10设置前轮。
[0028] 所述皮带 18设有齿牙 34， 电机出轴端与传动轴的皮带轮 35也相应的设置与之啮 合的齿牙， 工作吋电机轴对转动轴 19带动的圈数精准， 提高控制精确度； 所述 传动轴设置缓冲阻尼 31， 避免后支架 2在折叠吋发生撞击。
[0029] 所述缓冲阻尼包括凹凸配合的两个环形套 32， 在凸出部和凹进部之间设有硅胶 33， 两个环形套互相配合， 其间隙设置的硅胶 33起到缓冲作用。
[0030] 所述立撑 22包括带有弯折角度的两个分支 24， 所述两个分支轴连接在一起。
[0031] 双面齿牙弧 37充分利用了内部结构空间， 节约了传递工序， 又起到对内部结构 的支撑作用。 它稳定的把主动齿轮 36的转动传递给小齿轮， 起到放大转速比的 作用， 主动齿轮 36旋转 90-180度， 小齿轮就可以实现多圈的转动。
[0032] 小齿轮 23的转动带动丝杠 20旋转， 丝杆 38运动带动了与之配合的螺母 21发生直 线运动， 导致与螺母 21相连的两个分支的前端发生张幵或者并拢的变换。
[0033] 所述丝杠与立撑支架所设的支撑弧 37相抵， 保证丝杠 20上所设的小齿轮与齿牙 弧 37底面的齿牙紧密啮合。
[0034] 对所公幵的实施例的上述说明， 使本领域专业技术人员能够实现或使用本发 明。 对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的， 本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下， 在其它 实施例中实现。 因此， 本发明将不会被限制于本文所示的这些实施例， 而是要 符合与本文所公幵的原理和新颖特点相一致的最宽的范围。
