Description

一种折叠式交通工具的轮架折叠机构 一种折叠式交通工具的轮架折叠机构
技术领域
本实用新型属于折叠车配件，具体涉及一种折叠式交通工具的轮架折叠机构。
背景技术
折叠式交通工具具有可便于携带的优点，在折叠的使用过程中也不需要借助外来工具，通过手动自行将车折
叠或展开，折叠后，能够较方便的存放和移动，避免室外存放的不安全隐患。
当前多数折叠式交通工具外观同自行车相似或由自行车改装而成，其车架是通过两节车架管之间设置折叠机构
与快拆紧固件实现车架的折叠，车架折叠为横向对折，折叠工序复杂，折叠后外观不美观，而且体积较大，占
用空间较大，张牙舞爪，无法存放于汽车后备箱远距离携带。
如何设计一种折叠便捷，结构简单，成本低，折叠后体积小的折叠式交通工具成为本领域技术人员面临的技术
难题。
发明内容
针对上述的技术缺陷确定的技术问题是：设计一种折叠式交通工具的轮架折叠机构，折叠度高，折叠后体
积下，折叠速度快，过程方便快捷。
要解决其技术问题，所采用的技术方案为：设计一种折叠式交通工具的轮架折叠机构，前把架与踏板活动连接
，座椅支撑杆与踏板活动连接，后轮架活动连接于踏板底面，其特征在于，后轮架包括左轮架和右轮架，左右
轮架的折叠轴呈倾斜夹角，所述踏板底面设置限位收紧槽，所述轮架与踏板底面的贴合位置设置磁铁，所述左
右轮架折叠后呈V型。
本实用新型的有益效果为：折叠度高，折叠后体积小，折叠速度快，过程方便快捷。
左右轮架的折叠轴呈倾斜夹角，后轮架、后轮一分为二，在正常行驶中左右轮架合并在一起，形成一个整体的
后轮，需要折叠时，左右后轮分开，折叠在踏板下面，当踏板与前把架贴合时左右后轮分立在前轮两侧，这样
就节约了空间，缩小了折叠体积。
所述踏板底面设置限位收紧槽，用于在正常行驶状态把左右轮架卡紧，保证其形成一个整体后轮，不会因颠簸
等分离。
所述轮架与踏板底面的贴合位置设置磁铁，用于吸合轮架和踏板底面，保证在折叠状态时二者紧密贴合，不会
因自动等原因分离，增强折叠的稳定性和牢固度。
所述左右轮架折叠后呈V型，分立在前轮两侧，折叠度高，整车折叠体积小，在折叠状态时能够保证站立的稳
定性，使用者折叠完毕放手后不会倾倒。

具体实施方式
如图所示，一种折叠式交通工具的轮架折叠机构，前把架1与踏板2活动连接，座椅支撑杆3与踏板2活动连接，
后轮架4活动连接于踏板2底面，其特征在于，后轮架2包括左轮架5和右轮架6，左右轮架的折叠轴7呈倾斜夹角
，所述踏板2底面设置限位收紧槽8，所述轮架与踏板2底面的贴合位置设置磁铁9，所述左右轮架折叠后呈V型
。
折叠时先把左右轮架向着踏板2底面折叠，左右轮架从限位收紧槽8脱出，因为左右轮架的折叠轴7呈倾斜夹角
，左右轮架贴合到踏板2底面时自动左右分开，被磁铁9吸附折叠锁定，再向着车把架1折叠，此时左右后轮分
立在前轮两侧，操作者放手后整车折叠站立。后轮10包括左后轮和右后轮。
展开时，按照先前顺序，扳动左右后轮，克服磁铁9的吸附力，左右后轮与踏板2底面脱离，伸展进入限位收紧
槽8卡住，左右轮架与踏板2在同一平面上，左右轮合并为一个整体后轮10，使用者可以上车骑行。
折叠度高，折叠后体积小，折叠速度快，过程方便快捷。
左右轮架的折叠轴7呈倾斜夹角，后轮架4、后轮10一分为二，在正常行驶中左右轮架合并在一起，形成一个整
体的后轮10，需要折叠时，左右后轮分开，折叠在踏板2下面，当踏板2与前把架1贴合时左右后轮分立在前轮
两侧，这样就节约了空间，缩小了折叠体积。
所述踏板2底面设置限位收紧槽8，用于在正常行驶状态把左右轮架卡紧，保证其形成一个整体后轮10，不会因
颠簸等分离。
所述轮架与踏板2底面的贴合位置设置磁铁9，用于吸合轮架和踏板2底面，保证在折叠状态时二者紧密贴合，
不会因自动等原因分离，增强折叠的稳定性和牢固度。
所述左右轮架折叠后呈V型，分立在前轮两侧，折叠度高，整车折叠体积小，在折叠状态时能够保证站立的稳
定性，使用者折叠完毕放手后不会倾倒。
需要指出的是，上述实施方式仅是本实用新型优选的实施例，对于本技术领域的普通技术人员来说，在符合本
实用新型工作原理的前提下，任何等同或相似的替换均落入本实用新型的保护范围内。
