一种折叠车的车把架 一种折叠车的车把架
技术领域
本实用新型属于折叠车配件，具体涉及一种折叠车的车把架。
背景技术
折叠车具有可折叠、易操控、便于携带等优点，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，能够较方便的将其收纳于汽车后备箱或登机箱内。
目前的折叠车，包括电动折叠车与折叠自行车，两者外观相似，折叠部分一般由车把架折叠关节和立管折叠关节构成，通过车把架折叠，将前后两轮对折在一起，可减少车体的长度，但是对折之后增加了车体的宽度，体积粗笨，占用空间大，外观不美观，安全可靠性差，而且折叠起来的转角要求很高，不能适应各种折叠方式的需要。
实用新型内容
本实用新型所要解决的问题是：提供一种折叠车的车把架，能够实现伸缩调节，体积小巧、外形精美、安全可靠。
本实用新型是通过如下技术方案来实现的：
即一种折叠车的车把架，包括车把横管、立管与前叉，其特征在于：所述立管与前叉为双管式，两条立管分别设置于车把横管的左右两侧，两条前叉管对应套设于两条立管的外周，所述立管与前叉管之间的间隙设置滑套，所述前叉管外周设置快拆管夹，所述前叉管开设涨紧缝；所述立管与车把横管通过把立相连接；所述前叉管设置双管固定架，所述双管固定架与转向轴相连接，所述转向轴与车架相连接；所述两条前叉管分别设置于前轮两侧。
本实用新型的有益效果是：
1、本实用新型折叠车的车把架，能够实现立管与前叉的伸缩调节，结构简单，操作方便，手动操作无需几秒钟的时间，立管与前叉均为双管式，颠覆了传统车把、前叉的外观及横向折叠结构，外观简洁时尚，安全可靠性高，车辆折叠后，更加小巧美观。
2、立管与前叉管采用快拆管夹固定，保证固定稳定可靠的情况下，操作简单，拆装方便。
3、在快拆管夹设置处，前叉管开设涨紧缝，涨紧缝将这一端的前叉管分成左右两半部分，将立管套入前叉管的管体中，调节好车把架高度后，装好快拆管夹，快拆管夹的锁定作用能够使前叉管的左右两半部分牢固的抓紧立管，完成立管与前叉管的锁定并且稳定可靠，锁定与解锁都非常方便。
4、立管与前叉管之间的间隙内设置由耐磨塑料构成的滑套，滑套能够起到助滑的作用，使得立管与前叉管之间的滑动顺畅自如，保证车把架的伸缩性能，提高使用寿命。
附图说明
图1为本实用新型结构示意图；
图2为本实用新型车把与立管结构示意图；
图3为本实用新型立管与前叉管结构示意图；
如图中所示：1、车把横管；2、立管；3、前叉管；4、快拆管夹；5、涨紧缝；6、把立；7、双管固定架；8、转向轴；9、车架，10、前轮，11、轮轴。
具体实施方式
如图1-3所示：本实用新型一种折叠车的车把架，包括车把横管1、立管2与前叉，立管2与前叉为双管式，前叉包括两条前叉管3，两条立管2分别设置于车把横管1的左右两侧，两条前叉管3对应套设于两条立管2的外周，立管2与前叉管3之间的间隙设置滑套，前叉管3外周设置快拆管夹4，在快拆管夹4设置处，前叉管3开设涨紧缝5。
快拆管夹4用于立管2与前叉管3间的锁定与解锁，快拆管夹4为一圆环状管夹，具有一束紧部及活动锁部，束紧部具有供前叉管穿过的内套孔，活动锁部设有锁耳以配合螺栓，打开活动锁部调节螺栓就可以相应调节立管2与前叉管3的高度，即实现车把架的伸缩调节；调节完毕之后，拧紧螺栓，关闭活动扳手即完成立管2与前叉管3的锁定。
两条前叉管3，在快拆管夹4设置处开设涨紧缝4，涨紧缝4将这一端的前叉管3分成左右两半部分，将两条立管2分别套入两条前叉管3的管体中，调节好高度，装好快拆管夹4，快拆管夹4的锁定作用能够使前叉管3的左右两半部分紧抓立管2，完成立管2与前叉管3的锁定并且稳定可靠，锁定与解锁简单方便。
车辆折叠过程中，打开快拆管夹4，将两条立管2向下推动即可，直至两条立管2完全穿入两条前叉管3的管体中，关闭快拆管夹4即完成车把架的收缩，手动调节，操作简单。
车辆展开过程中，打开快拆管夹4，将两条立管2向外拉出，调节至适当高度，关闭快拆管夹4即完成车把架的伸展。
立管2与车把横管1通过把立6相连接。
前叉管3设置双管固定架7，双管固定架7后端设置转向轴支架，转向轴支架用以安置转向轴8，转向轴8与车架9相连接。
两条前叉管3分别设置于前轮10的两侧，两条前叉管3的末端分别设置轴孔，前轮10的轮轴11穿过两侧轴孔并得到固定，完成两条前叉管3与前轮的连接。
本方案立管2与前叉管3之间滑套采用耐磨塑料材料制成，如尼龙或者POM等，具有较强的耐磨性与良好的光滑度，能够避免立管2与前叉管3的管壁发生直接摩擦，使得两者间的滑动顺畅自如，保证伸缩性能。
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。
