Description

交叉杆型单车结构 技术领域
本创作系有关于单车车架结构，尤其是一种交叉杆型单车结构。
背景技术
单车为一种非常普遍的交通工具，由于单车具有轻便的特性，且不须使用汽油，因此也是低污染的交通工具。一般的单车车架结构，其主架结构之配置形状类似由两个基本三角形所形成，两者共享一主杆，第一个三角形结构利用前叉杆连结前轮1，第二个三角形结构连结后轮2，此为最常见的车架结构形式。惟目前市面上的单车主要都属于上述结构，因此其结构强度有所受限，且在外观上较无变化，因此显得死板。因此无法给予使用者较良好的使用体验。
技术问题
由于目前材料技术的进步，可以应用高强度的材料构成具有流畅型态的刚性结构零组件，而可以取代传统的设计结构中的零组件，甚至在减少设计结构中的组件数量下保持良好的刚性结构，因此可以让产品拥有更好的结构强度且具有更多样化的外观型态。故本案希望提出一种崭新的具有强化结构及流畅外型之车架的单车，以解决先前技术上的缺陷。
