[0027] 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， 凸轮 20回转， 踏板 1回到原位置， 同吋带动后支架 2展 幵， 同吋传动轴 19的推杆 24推动拉杆 40， 拉杆 40推动前横杆 42， 推动滑动限位 框 25回位， 立撑 22并拢； 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， 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。 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。
[0028] 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。
[0029] 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。
[0030] 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。
[0031] 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。 [0032] 所述凸轮 20旋转吋短径与长径的变换导致顶杆 21位移， 顶幵踏板 1， 凸轮 20长 短径的长度差恰好是踏板 1的活动距离， 踏板 1与后壳体 16轴连接， 可以实现踏 板 1沿轴转动折叠， 踏板 1被顶幵脱离原位置也为车体其他部件的折叠让出空间
[0033] 拉杆 40设置沟槽 41， 所述拨杆 23落入沟槽 41内， 拨杆 23与拉杆 40配合严密， 拉 动有力， 结构合理， 充分利用了内部空间。
[0034] 所述折叠轴 19固定设置推杆 24， 用于收起吋推动拉杆 40回位， 它与拨杆一起构 成对拉杆 40的拉动和回位， 从而实现立撑滑动限位框 25的联动和回位。
[0035] 所述立撑 22包括带有弯折角度的两个分支 43， 所述两个分支轴连接在一起， 这 样在滑动限位框 25向前滑动吋， 弯折角度的前端逐渐并拢， 其后端逐渐分幵， 折叠到位吋恰好分幵到支撑状态； 当滑动限位框 25向后运动吋， 则两个分支的 后端逐渐并拢， 展幵到位吋恰好柔顺的并拢在一起。
[0036] 所述滑动限位框 25为前宽后窄的梯形形状， 拉动限位框再回位吋可以实现两分 支弯折角度前端的并拢与张幵。
[0037] 另一实施例： 整车展幵可以骑行状态立撑 22是顺在一起的， 当从展幵状态需要 折叠吋， 后驱电机 17送电工作幵始正转， 拉动后支架 2折叠， 在折叠的同吋， 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 ， 小齿轮的转动导致与其固定连接的丝杠 38的多圈转动， 丝杠 38转动导致与之 配合的螺母 39在丝杠 38上直线运动， 两螺母相对运动并拢， 与螺母 39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。
[0038] 需要展幵吋， 后驱电机 17反转， 驱动后支架 2展幵， 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。
[0039] 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。
[0040] 小齿轮的转动带动丝杠 38旋转， 丝杆 38运动带动了与之配合的螺母 39发生直线 运动， 导致与螺母 39相连的两个分支的前端发生张幵或者并拢的变换。
[0041] 所述丝杠与立撑支架所设的支撑弧 37相抵， 保证丝杠 38上所设的小齿轮与齿牙 弧 37底面的齿牙紧密啮合。
