Description

一种折叠车
本申请要求于2016年05月31日提交中国专利局、申请号为201610377341.X、发明名称为“一种折叠车”，以及于2016年05月31日提交中国专利局、申请号为201620517291.6、发明名称为“一种折叠车”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及微型代步车生产技术领域，尤其是涉及一种折叠车。
背景技术
随着生活水平的提高，人们的生活需求也越来越多样化，适合城市短距离出行且携带方便的折叠车被越来越多的消费者所选择。
一般情况下，折叠车在收纳之后适合手拎、放置在工具包或者汽车后尾箱内，因而极轻、极简已经成为了折叠车所追求的目标。
如图1中所示，其展示了目前可查询到的一种较为轻便的折叠车，其车架主体是由两个相互铰接的环状构件01所形成，前车轮和后车轮分别设置在前后两个环状构件01上，在进行折叠时，车架主体的前后两个环状构件01绕其中间的铰接部旋转后相互贴合，前轮和后轮分别嵌入到两个环状构件01内。虽然这种折叠电动车实现了方便折叠，但是由于其车架折叠后形成了两个相互贴合的环状构件01，车架主体的用料和结构仍然不够精简，这使得目前折叠电动车整车的重量维持在15kg-20kg左右，整体在厚度方向上的尺寸也较大，携带仍然不是非常方便，尤其是不能放在背包等便携包中。
因此，如何能够进一步降低折叠车的车重以及折叠后所占用的体积，以进一步提高折叠车的便携性是目前本领域技术人员亟需解决的技术问题。
发明内容
本发明的目的是提供一种折叠车，以便能够进一步降低折叠车的车重以及折叠后所占用的体积，以进一步提高折叠车的便携性。
为达到上述目的，本发明所公开的折叠车，包括车架主体，所述车架主体包括通过折叠机构相连的前部开口环和后部开口环，并且在折叠后所述前部开 口环和所述后部开口环形成一个闭合环体。
优选的，所述折叠机构为带有锁止装置的抽拉式伸缩节，所述前部开口环与所述抽拉式伸缩节的前端相连，所述后部开口环与所述抽拉式伸缩节的后端相连。
优选的，所述抽拉式伸缩节具体为一套，所述抽拉式伸缩节的前端与所述前部开口环的上部接口相连，后端与所述后部开口环的上部接口相连；或者，
所述抽拉式伸缩节的前端与所述前部开口环的下部接口相连，后端与所述后部开口环的下部接口相连。
优选的，所述抽拉式伸缩节包括上部伸缩节和下部伸缩节，其中，所述上部伸缩节的前端与所述前部开口环的上部接口相连，后端与所述后部开口环的上部接口相连；所述下部伸缩节的前端与所述前部开口环的下部接口相连，后端与所述后部开口环的下部接口相连。
优选的，所述前部开口环的底端与所述后部开口环的底端相铰接后构成所述折叠机构，且铰接位置处还设置有锁止装置，所述前部开口环的上端与所述后部开口环的上端均为自由端。
优选的，所述前部开口环的上端与所述后部开口环的上端相铰接后构成所述折叠机构，且铰接位置处还设置有锁止装置，所述前部开口环的底端与所述后部开口环的底端均为自由端。
优选的，所述前部开口环的下部为可转动的前叉，前轮可翻转地设置于所述前叉上，后轮可翻转地设置于所述后部开口环上，且在折叠后，所述前轮翻转至所述闭合环体的一侧并嵌入所述闭合环体，所述后轮翻转至所述闭合环体的另一侧并嵌入所述闭合环体。
优选的，由所述前部开口环上部穿入的车把组件与所述前叉相连，所述车把组件包括车把立管和设置在车把立管顶端的握把，且所述车把立管为带有锁止装置的伸缩管。
优选的，所述握把的外端可朝向所述折叠车的内侧弯折，且在折叠后，所述握把形成供用户提起所述折叠车的提手。
优选的，所述后部开口环的上部还设置车座组件，所述车座组件包括车座立管和设置在所述车座立管顶端的车座，所述车座立管为带有锁止装置的伸缩 管。
优选的，还包括设置在所述前部开口环或所述后部开后环上的折叠式脚踏板，所述折叠式脚踏板折叠后嵌入所述闭合环体。
优选的，所述前部开口环和所述后部开口环均为半圆环。
由以上技术方案可以看出，本发明所公开的折叠车中，包括车架主体，并且车架主体包括通过折叠机构相连的前部开口环和后部开口环，在折叠后，前部开口环和后部开口环形成一个闭合环体。
由于车架主体由两个开口环构成，两个开口环在折叠之后将形成一个闭合的环体，相比于现有技术而言，该折叠车在折叠之后仅具有一个闭合环体，因而有效减小了折叠车所占用的空间，同时因为用料的减少，整车车重也显著降低，这就使得该折叠车的便携性大大提高。

具体实施方式
本发明的核心是提供一种折叠车，以便能够进一步降低折叠车的车重以及折叠后所占用的体积，以进一步提高折叠车的便携性。
为了使本技术领域的人员更好地理解本发明方案，下面结合附图和具体实施方式对本发明作进一步的详细说明。
本发明中所公开的折叠车，实际上包括但不限于电动车、自行车、滑板车 等，该折叠车包括车架主体，该车架主体包括通过折叠机构3相连的前部开口环1和后部开口环2，并且在折叠后该前部开口环1和后部开口环2形成一个闭合的环体。
在上述实施例中，由于车架主体由两个开口环构成，两个开口环在折叠之后将形成一个闭合的环体，相比于现有技术而言，该折叠车在折叠之后仅具有一个闭合环体，因而有效减小了折叠车所占用的空间，同时因为用料的减少，整车车重也显著降低，这就使得该折叠车的便携性大大提高。
本领域技术人员理解的是，折叠机构3的实现形式并不局限于一种，例如在本发明实施例中，折叠机构3为带有锁止装置的抽拉式伸缩节，前部开口环1与抽拉式伸缩节的前端相连，后部开口环2与抽拉式伸缩节的后端相连，锁止装置可以采用目前通用的形式，例如定位销、顶珠等。需要进行说明的是，在本实施例中，以折叠车行驶的方向为前，因而抽拉式伸缩节也就具有了前后两端之分，前部开口环1和后部开口环2同样是基于该基准进行的命名。
一种具体的实施例，如图2中所示，抽拉式伸缩节具体包括一套，该抽拉式伸缩节的前端与前部开口环1的上部接口相连，后端与后部开口环2的上部接口相连。该抽拉式伸缩节至少包括截面不同的三个节段，每一个节段均能够缩入相邻的较大的一节中，从而缩短整体的长度，当该抽拉式伸缩节完全缩回时，前部开口环1和后部开口环2的底部也刚好相接构成闭合环体。更进一步的，抽拉式伸缩节内相邻的两个节段之间可以通过滚轮、轴承或者滑块相连，以便实现顺利的抽拉，在伸缩到位后，锁止装置将抽拉式伸缩节锁止，以防止伸缩节的旋转和松动。
需要进行说明的是，上述实施例中，由于一个开口环具有两个端部，位于上面的端部称为上部接口，位于下面的端口称为下部接口。
前部开口环1的下部为可转动的前叉4，如图2中所示，前轮5通过前轮架6可翻转地设置在前叉4上，后轮13通过后轮架7可翻转地设置在后部开口环2上，并且在折叠后，前轮5翻转至闭合环体的一侧并嵌入闭合环体内，后轮13翻转至闭合环体的另一侧并嵌入闭合环体内，如图3中所示。当然，前轮5和后轮13处应当设置锁止装置，该锁止装置在前后轮展开或者前后轮折叠后起到锁止作用，防止前后轮松动。
前部开口环1的上部穿入车把组件，车把组件的底端与前叉4相连，车把组件与前部开口环1之间通过碗组、培林和轴承等零件相互配合，其配合的具体结构可参照现有自行车中车把与车架的配合方式，本文中对此不作赘述，车把组件具体包括车把立管8和设置在车把立管8顶端的握把9，如图2中所示，并且该车把立管8为带有锁止装置的伸缩管，车把立管8上的锁止装置优选的为定位销或顶珠，当然，也可以为螺丝或者快拆扳手等。
相比于现有技术而言，上述实施例中的折叠车在进行转向时车把仅需带动前叉4转动，而无需带动整个前部开口环1转动，这使得车辆的转向更加轻盈省力，客户的舒适性体验更好。
更进一步的，握把9的外端还可以朝向折叠车的内侧弯折，弯折之后与闭合环体的平面平行，在折叠后，握把9形成供用户提起折叠车的提手，如图3中所示。
除此之外，考虑到舒适性，还可在后部开口环2上部设置车座组件，如图2中所示，车座组件包括车座立管10和设置在车座立管10顶端的车座11，并且车座立管10也为带有锁止装置的伸缩管，车座立管10的锁止装置优选的为定位销、顶珠、螺丝或者快拆扳手等。如图3中所示，车座立管10和车座11在折叠后也实现了隐藏，从而有效减小了折叠车占用的体积。
当然，设置车座后就需要考虑设置脚踏板，为此，本实施例中所公开的折叠车还包括设置在前部开口环1或者后部开口环2上的折叠式脚踏板12，如图2中所示，折叠式脚踏板12在折叠后也能够嵌入闭合环体内，以便最大程度的节省空间。
除此之外，当抽拉式伸缩节包括一套时，该抽拉式伸缩节的前端还可以与前部开口环1的下部接口相连，后端与后部开口环2的下部接口相连，如图4中所示。该抽拉式伸缩节至少包括截面不同的三个节段，每一个节段均能够缩入相邻的较大的一节中，从而缩短整体的长度，当该抽拉式伸缩节完全缩回时，前部开口环1和后部开口环2的顶部也刚好相接构成闭合环体。更进一步的，抽拉式伸缩节内相邻的两个节段之间可以通过滚轮、轴承或者滑块相连，以便实现顺利的抽拉，在伸缩到位后，锁止装置将抽拉式伸缩节锁止，以防止伸缩节的旋转和松动。
当然，抽拉式伸缩节还可包括两套，位于上部的抽拉式伸缩节称为上部伸缩节，位于下部的抽拉式伸缩节称为下部伸缩节，其中上部伸缩节的前端与前部开口环1的上部接口相连，后端与后部开口环2的上部接口相连；下部伸缩节的前端与前部开口环1的下部接口相连，后端与后部开口环2的下部接口相连，如图5中所示。该实施例中抽拉式伸缩节的具体结构可参照图2和图4中抽拉式伸缩节的结构设计。
可以理解的是，折叠机构3还可通过铰接的方式实现，请参考图6，在本实施例中，前部开口环1的底端与后部开口环2的底端铰接后构成折叠机构3，并且铰接位置处还设置有锁止装置，前部开口环1的上端和后部开口环2的上端均为自由端。在该实施例中，锁止装置优选的为定位销。需要说明的是，在本实施例中，前部开口环1和后部开口环2的底端是指在完成折叠后，两个开口环位置较低的一端被称为底端。
当然，本领域技术人员容易想到的变通是，前部开口环1的上端与后部开口环2的上端相铰接后也可构成折叠机构3，且铰接位置处也应当设置锁止装置，前部开口环1的底端与所述后部开口环2的底端均为自由端。本实施例中前部开口环1底端和后部开口环2底端的定义方式与上一实施例中相同。
如图4至图6中所示，为了能够调节握把9与人体的距离，还可在车把立管8上设置车把调节机构，该车把调节机构应当包括设置在车把立管8上，可沿靠近或远离人体方向旋转的握把安装杆，握把9安装在握把安装杆上，并且还具有对握把安装杆进行锁止的锁止装置。
不难理解的是，所谓闭合环体的形状多种多样，例如椭圆形、矩形、多边形等等，只要是具有封闭形状的环体均可称为闭合环体，考虑到折叠后占用的体积以及折叠后的美观，本发明实施例中的前部开口环1和后部开口环2均为半圆环，折叠后所形成的闭合环体为圆环，前轮5和后轮13在折叠后刚好可嵌入圆环内，从而最大程度的减小折叠后的车辆所占用的空间，并增加折叠后的美观程度。
整车可以采用铝合金、铝镁合金、钢、或者碳纤维来进行制作，经实际验证，少部分结构采用碳纤维，大部分结构采用铝合金时，本发明中所公开的折叠车若做成电动车，当其最大续航在20公里左右时，其整体重量可以控制在 5kg左右，并且其折叠后的体积足以保证其放入双肩背包中背在背上，这大大提升了折叠车的便携性能，做到了极轻、极简和极美的程度。
以上对本发明所提供的折叠车进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
