新型电动助力自行车的结构设计

摘要电动助力自行车与普通自行车靠人力驱动，现有电动车驱动时无需蹬踏的反人类设计(且断电时骑行困难)相比优势明显，具有骑行非常自如省力（即使断电），符合人类运动特性，环保轻便，是快捷交通、代步工具的不二选择。47538

本课题在研究分析国内外电动助力自行车行业标准，国内外市场上已有电动助力自行车产品的基础上，设计出了一种新型的电动助力自行车结构，此结构根据使用者脚踏骑行的踏力引起的链条张紧力，通过“助力-检测装置”检测蹬踏力，最终反馈给控制装置。该结构具有简单，轻便，创新，价格低廉诸多优点，将在文中具体阐述。

Title Structure Design of a New Electric Assisted Bicycle

Abstract

Electric power assisted bicycle and the bicycle is driven by manpower, electric vehicle drive without pedaling against humanity design, power cycling difficult, electric power car in three obvious advantages, with ride very comfortable and labor-saving (even if the power), in line with the characteristics of human motion, light green, is a high-efficient traffic and transport choice.

This paper analyzes the study abroad industry standard power-assisted bicycle, based on domestic and foreign markets have been the product of an electric assist bicycle on the design of a new type of electric assist bicycle structure, which according to the user's foot ride pedaling force chain tension caused by "power - detecting means" detected pedaling force, and ultimately back to the control unit. The structure is simple, lightweight, innovative, low-cost advantages, will be specifically addressed in the text.
