[0026] 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， 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 2 7的卷线被渐渐放松， 直至弹入销孔 26锁定后支架。
[0027] 其连接轴设置阻尼垫 24， 可以实现座椅杆 11解锁后缓缓向前倾倒， 避免激烈碰 撞造成不必要的损伤。
[0028] 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。 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。 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。 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 12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。 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
[0031] 所述立撑 22包括带有弯折角度的两个分支 40， 所述两个分支轴连接在一起。
[0032] 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。
[0033] 小齿轮 23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。
[0034] 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。
