Abstract

折叠式两用人力车，它主要是经过伸缩折叠后可将人力脚踏车变为人力小推车，它的主要特征是将原人力脚踏车的车架拆成三段，用两个折叠活结链接起来，经折叠后前后两轮的人力脚踏车变为两轮并排的人力小推车，转换了使用功能。

Description

折叠式两用人力车
本发明的技术领域：是一种可以通过伸缩和折叠而变形为人力脚踏车或人力小推车的机械车辆. 
背景技术：目前的折叠式人力脚踏车都是将其折叠后缩小体积而无其他用途。 
发明内容：本发明的目的是将人力脚踏车折叠后，人们可以把它作为小推车使用，变换了使用功能。 
本发明的技术方案是：将原脚踏车的链条传动改为皮带传动。将原脚踏车的车架改为三节式折叠车架，中间横梁节由两小节套装组成能伸缩变换长度。折叠后的车架呈U字型结构，前后两轮变成两平行轮。车把和车座设计成可拆装的形式，折下后可装在U型车架上变成小推车的推杆。 
本发明对原人力脚踏车的结构做了部分改动，将原车架变成了折叠式的伸缩车架，将原来的金属链条传动改为皮带传动，经上述变动后原前后两轮的人力脚踏车可变换成两轮并排的人力小推车了。 
图1：是实施例的主视图 
图2：是实施例折叠后的顶视示意图 
图3：是实施例车架中间节的结构示意图 
下面结合附图对本发明加以详细说明，为了图示清晰，车体的细节部分均未画出，无关部件也未作标注。 
图1中E是车架中间节的前段，F是车架中间节的后段，L是螺杆、H是螺母，A、B是两个折叠关节，C是传动皮带，Q是脚踏车 前轮，M是脚踏车后轮。 
从图1和图2中可以看出从人力脚踏车车架总成上增加了两个折叠关节A、B，将车架可以折成一个U字型，从而实现了将前后的两轮变成了平行的两轮即可实现手推车的功能了。 
从图3中可以看出：车架折成U型后，中间节的前端露出螺杆L的螺帽，旋转该螺帽即可调节车架长度。
