Description

一种翻座箱式折叠电动车 技术领域
本发明涉及一种可折叠电动车，尤其是一种折叠和展开便易且折叠后横向占空间较小、后轮着地的翻座箱式折叠电动车。
背景技术
随着城市化的发展，交通拥堵尤其是早晚高峰时的拥堵越来越严重，汽车带来的环境污染也越来越严重，自行车，包括电动自行车，以其环保、经济、行驶灵活的特点逐渐成为人们短距离交通的首选。也有部分居民需要乘骑自行车结合公共交通工具才能到达目的地，但是普通电动车的体积大且笨重不便带入公共交通工具或室内，很大程度的限制了电动车的使用。为解决上述问题，人们引入了折叠技术将自行车做得更小巧更便携。但是，目前市场上的折叠自行车或多或少的存在如下缺陷：一、折叠不够彻底，多有棱角和伸出物，带入公交车/地铁等人多的空间仍有不便；二、折叠需要复杂的控制和联动机构，折叠步骤多而麻烦；三、折叠后车体不能拖行或推行需要肩扛手拎。因此，亟需一种结构简单、折叠和展开便易且折叠后形状简洁便于携带的自行车。
发明内容
本发明目的是，提出一种可折叠电动车及其折叠方法，尤其是一种折叠和展开方便快速、且折叠后体积紧凑、横向占空间小，能够后轮着地携带的翻座箱式折叠电动车。
本发明的技术方案是，一种可折叠电动车，其特征在于包括前轮组件、中央车架、后轮、座板和对称设置在中央车架两侧的尾架、座板支撑杆；
中央车架的前部连接前轮组件；
中央车架的后上角铰接座板，座板可翻转折叠于中央车架上方；
中央车架的后下角与尾架的前端可转动地连接，尾架的最后端安装后轮；
中央车架和/或尾架上设有限位机构，用于限定尾架的展开角度；
座板支撑杆为一对伸缩杆，用于支承座板和人体重量，其下端与尾架的后端可转动地连接，其上端与座板侧面可转动地连接，翻转座板时座板支撑杆会随着座板转动并改变长度。
座板可以是一整块，也可以是铰接的两节。一整块座板结构简单，但两节的 形式可以得到更紧凑的折叠效果，或更长的车座。
进一步的，座板支撑杆上端设有向后方伸出的托架结构，用于限位座板的展开角度，使得车体展开时尤其是骑行时结构更稳定。
优选的，可折叠电动车还包括踏板、回位弹簧和踏板牵索，尾架在展开时的下边缘铰接踏板的中部，踏板牵索分别连接踏板内侧和中央车架的前下部，特别是分别交叉连接不同侧的踏板内侧和中央车架前下部，两踏板的外侧通过回位弹簧牵引，使得尾架折叠时，踏板牵索放松，两侧踏板在弹簧牵拉下向中央车架靠拢；尾架展开时，踏板牵索拉紧将踏板水平展开。
进一步的，踏板与尾架之间也可以用弹簧铰链实现回位，这样回位弹簧可以省略。
前轮的尺寸可小于后轮的尺寸，使得折叠后体积更小。
作为进一步的改进，可以通过增加限位块或滑槽结构及相应的限位机构，使得尾架不仅可以绕中央车架旋转，同时还能纵向滑动，即当尾架向外旋转展开时，其向外滑动，使得后轮伸展更远，而当尾架向内旋转折叠时，其向内滑动，使得车轮靠近中央车架，车体更小。特别是，在折叠位，车身在重力的作用下自然下沉，尾架相对内缩，并利用限位装置使得尾架侧向得到限位，实现尾架在折叠竖直状态下的稳定自锁状态。
本发明的可折叠电动车的折叠方法包括以下操作：
一、将座板翻转折叠于中央车架上方，座板支撑杆会随着座板转动并改变长度，直至贴紧折叠位置，支撑杆始终连接着座板和尾架；
二、向上、后提拉中央车架，带动前轮离地，同时尾架自然相对回收呈垂直状态。在尾架回收的过程中，踏板牵索放松，踏板在回位弹簧的作用下回到平行贴紧尾架的状态。
进一步的，为了减小折叠车车体的前后长度，还可以包括如下操作：
三、转动前轮组件，使前轮转动到近似与后轮垂直。
四、折叠车把手，使体积更小。
展开过程与折叠过程相反。
相对于现有技术，本发明的可折叠电动车有如下优点：1)折叠机构可靠且折叠便易，仅需二到四步即可完成折叠；2)折叠后体积紧凑、横向占空间小，能够 后轮着地携带，特别是当后轮引入智能平衡控制，非常方便沿地面平衡推行，大大减轻了携带的负重，且因体积小，便于使用者携带乘座轨道交通，对他人的影响小。现有技术鲜有本发明这样用途广泛的电动车折叠结构。总之，本发明是结构简约、行驶可靠(可与常规电动车一样出行)的翻座箱式折叠电动车。

具体实施方式
图1、4、5、6是本发明车体从展开到折叠的过程，图2、3、7分别为座板底面和脚踏部分的局部放大图。
本发明的技术方案是，一种可折叠电动车，包括前轮组件1、中央车架2、后轮、座板3和对称设置在中央车架两侧的尾架4和座板支撑杆5，中央车架2的前部连接前轮组件1；中央车架2的后上角铰接座板3，座板3可翻转折叠于中央车架2上方；中央车架2的后下角与尾架4的前端可转动地连接，尾架4的最后端安装后轮；中央车架2和/或尾架4上设有限位机构，用于限定尾架4的展开角度；座板支撑杆5为一对伸缩杆，用于支承座板3和人体重量，其下端与尾架4的后端可转动地连接，其上端与座板3侧面可转动地连接，翻转座板3时座板支撑杆5会随着座板3转动并改变长度。所述中央车架2既是连接前轮组件1、座板3和尾架4的结构组件，又可以提供储物空间，还能够用于放置电动车电池和控制器。电动车的电池和控制器也可以位于尾架4内侧，设置在左右侧尾架的下部的连接件之上，所述连接件可以是整块板件、网格或间隔的肋条。所述中央车架可以是具有完整侧壁和底部的箱体，也可以只是箱形的框架。纺织物制成的储物袋套在箱体框架中或套在箱体框架外即可实现储物的功能。座板3可以是一整块，也可以是铰接的两节。一整块座板结构简单，但两节的形式可以得到更紧凑的折叠效果，或更长的车座。用于限定尾架的展开角度的限位机构，可以设置在中央车架2或尾架4上，如图1所示在中央车架下部设置突出的限位块6；也可以是由中央车架和尾架上的两部分配合而起到限位作用，如公开号为CN201999140U公开日为2011.10.05的实用新型专利，由弧形长形槽和拉力弹簧配合实现展开角度的限位；也可以在中央车架和尾架的预设的展开位置处开设销孔，用轴销实现限位。
进一步的，座板支撑杆5上端设有向后方伸出的托架结构，用于限位座板3 的展开角度，使得车体展开时尤其是骑行时结构更稳定。
优选的，可折叠电动车还包括踏板7、踏板牵索8和回位弹簧9，尾架4的下部铰接踏板7的中部，踏板牵索8分别交叉连接不同侧的踏板内侧和车架下部，或者连接同侧的踏板内侧和车架下部，两踏板的外侧通过回位弹簧9牵引，使得尾架折叠时，踏板牵索8放松，两侧踏板在回位弹簧9牵拉下向中央车架靠拢；尾架展开时，踏板牵索8拉紧将踏板7水平展开。
进一步的，踏板7与尾架4之间也可以用弹簧铰链实现回位，这样回位弹簧9也可以省略。
优选的，前轮的尺寸可小于后轮的尺寸，使得折叠后体积更小。
进一步的，为了折叠后车体能够保持折叠状态，可以设置机械或电磁卡扣结构来固定车体不同组件的位置关系。
优选的，折叠电动车的把手以可伸缩或者可折叠的方式连接前轮组件的竖管部分，以进一步减小折叠后车体的宽度；控制开关安装在把手上，电机安装在后轮，接线尽量置于把手、前叉组件、下横杆的内腔中，以减少外露部件数量，储物箱或箱体框架、下箱体设置圆角，以使车体更简洁美观，避免刮蹭和勾拉。
本发明的可折叠电动车的折叠方法包括以下操作：
一、将座板3翻转折叠于中央车架2上方，座板支撑杆5会随着座板3转动并改变长度，且保持两端的连接不变；
二、向后、上提拉中央车架2，带动前轮离地，后轮相对前移到中央车架2下方，尾架4接近垂直。
进一步的，为了减小折叠车车体的前后长度，还可以包括如下操作：
三、转动前轮组件1，使前轮转动到近似与后轮垂直。
四、折叠车把手，使体积更小。
进一步的，可以通过增加限位块或滑槽结构及相应的限位机构，使得尾架4不仅可以绕中央车架旋转，同时还能纵向滑动，即当尾架向外旋转展开时，其向外滑动，使得后轮伸展更远，而当尾架向内旋转折叠时，其向内滑动，使得车轮靠近中央车架，车体更小。特别是，在折叠位，车身在重力的作用下自然下沉，带动尾架内缩，并利用限位装置使得尾架侧向得到限位，实现车身在折叠竖直状态下的稳定自锁状态。这样车身展开时前后长度增大，骑行者体态舒展，而又不 会增大折叠后的体积。
具体的限位方式如图8、9所示，所述限位机构包括转轴10、尾架滑槽11以及不规则限位块12，尾架4接近前端开设尾架滑槽11，中央车架2上固定有转轴10，其穿过所述尾架滑槽11，使尾架4沿转轴可以平行滑动，中央车架2的相应位置设有限制尾架前端运动轨迹的不规则限位块12，限位块12内侧表面在尾架4转动时与尾架4前端接触，使得车体展开时尾架滑槽的前端和所述转轴接触得到限位，尾架4沿自身长度方向向外滑动，后轮伸展到最远位置；车体折叠时尾架滑槽的后端被转轴限位并保持稳定。
一种替代的限位方式如图10、11所示，所述限位机构包括转轴10、轴销13、尾架滑槽11以及曲线滑槽14，尾架4接近前端开设尾架滑槽11，中央车架下后部固定有转轴10，其穿过所述尾架滑槽11，尾架最前端固定有垂直向内的轴销10，中央车架2相应位置设有曲线滑槽14，所述轴销13可以在曲线滑槽中滑动，使得车体展开时尾架4最前端的轴销滑动到曲线滑槽的最下部，并使尾架4沿自身长度方向向外滑动，后轮伸展到最远位置；车体折叠时，尾架最前端的轴销滑动到曲线滑槽的最上部，使得尾架4沿自身长度方向向内滑动，后轮最接近中央车架并保持稳定。
另一种替代的限位方式如12-14所示，所述限位机构包括轴销13以及滑槽15，尾架4前端设有两根轴销13，两根轴销间隔固定，中央车架2的下部设有一特定形状的滑槽15，尾架的轴销可在滑槽中滑动，滑槽15的形状使得车体展开时尾架4的轴销滑动到滑槽的底面并保持稳定，车体折叠时尾架4的轴销滑动到不规则滑槽的最上端并保持稳定。
再一种替代的限位方式如15-21所示，所述限位机构包括尾架轴16以及滑槽17，所述尾架4沿长度方向开有供尾架轴16滑动的滑槽17，滑槽17包括最前端的分支部分171和其他部分172，所述分支部分171设置为两段扇形分支或S形分支，使得当尾架4前端滑到尾架轴6位置时，尾架4能够在尾架轴16的限位下旋转，在其他位置时尾架4沿滑槽的其他部分172下落或滑升，改变整车高度。如15-21所示，尾架轴16为两个或多个在中央车架上成上下分布的轴销。相应的，滑槽17的最前端可以为两段扇形分支或S形分支，当然，滑槽的最前端为扇形分支也是可以的。该技术方案中，所述尾架轴16设置为在中央车架2 上成上下分布的轴销，数量为两个，滑槽17最前端为分支部分171设置为S形分支，具体参见图16-1。
再一种替代的限位方式如22-29所示，所述尾架轴16为在中央车架2上成上下分布的一个或多个扁平轴18，滑槽17最前端的分支部分171设置为扇形分支，优选的，扁平轴18与滑槽17接触的地方为较为光滑的曲面以减小摩擦。其余结构与图15中所述的结构相同，图15—图29这两种方案所述的限位机构，中央车架上不需要开槽，中央车架作为整车的结构支撑件，强度不受影响；若以中央车架内部作为电池、控制器等的存储空间，则该部分空间形状可以做的很规则，提高空间利用率，车体折叠和展开时限位的稳定性更好。
这样，车体需要折叠时，将座板3翻转于中央车架2上方，座板支撑杆5随着座板3的转动而转动并改变长度，向上提拉中央车架2或前轮组件1，此时在滑槽17最前端的滑槽的分支部分171的限位下，尾架4由于重力作用绕尾架轴16旋转向竖直方向靠拢；尾架轴16滑动到滑槽的分支部分171与滑槽的其他部分172的连接处后，在滑槽的其他部分172的限位下，由于重力作用，尾架轴16沿滑槽的其他部分172下滑带动中央车架2自然下落并稳定自锁，车体高度降低。而当车体需要展开时，上提中央车架2或前轮组件1，尾架轴16沿滑槽的其他部分172上滑；尾架轴16滑动到滑槽的分支部分171与滑槽的其他部分172的连接处后，给尾架4或座板支撑杆5或后轮一个向后的力，此时在滑槽的分支部分171的限位下，尾架4绕尾架轴6旋转远离竖直位置，直至尾架轴16旋转到滑槽的分支部分171的极限位置，将座板3翻转展平，板座支撑杆5随着座板的转动而转动并改变长度，此时在车体自重和/或骑乘者体重的作用下，尾架4实现稳定自锁。所述滑槽的其他部分172可以为直线形的，也可以为曲线形的。
作为本发明的一种改进，参见图30，为了增加可折叠电动车的支撑强度，所述限位机构还包括一个连接在中央车架和尾架的连接件20，所述连接件20与中央车架2和尾架4之间构成稳定可释放的三角支撑关系，车体展开时与中央车架2和尾架4形成稳定的三角形，车体折叠时连接件20放松，三角形破坏，该连接件可以应用在上述任何一种折叠电动车上，该连接件20主要用于增加电动车的支撑强度，使得电动车的承载范围更加广泛，适用性更好，使用时间更长。
相对于现有技术，本发明的可折叠电动车有如下优点：1)折叠机构可靠且折叠便易，仅需二到四步即可完成折叠；2)折叠后体积紧凑、横向占空间小，能够后轮着地携带，大大减轻了携带的负重，且因体积小，便于使用者携带乘座轨道交通，对他人的影响小。现有技术鲜有本发明这样用途广泛的电动车折叠结构。总之，本发明是结构简约、行驶可靠(可与常规电动车一样出行)的翻座箱式折叠电动车。
以上所述仅为本发明的优选实施例，并不用于限制本发明，对于本领域的技术人员来说，可以将上述技术方案中的两个或者多个进行重新组合，形成新的实施方式；凡在本发明的精神和原则之内，所作的任何修改、改进等，均应包括在本发明的保护范围之内。
