摘要

本文主要论述了以重力势能驱动具有方向控制功能的自行小车的研究设计。应用Auto CAD对齿轮及各机构的二维设计，Pro/EngineerWildfire 3.0实现了各个零件的三维设计。

本作品是依据竞赛命题主题“无碳小车”，提出一种“无碳”方法，带动小车的运行，即给定一重力势能，根据能量转换原理，设计了一种可将该重力势能转化为机械能并用来驱动小车行走的装置。该自行小车在前行时能够自动避开赛道上设置的障碍物（每间隔1米，放置一个直径为20mm，高为200mm的弹性障碍圆棒）。此模型最大的特点是将重力势能转化为齿轮的转动，进而根据大小齿轮的粘合带动驱动轮和转向轮，从而按照规定的路线完成任务。本文将对无碳小车模型的设计过程，结构功能特点等进行详细的介绍，并阐述了本作品的创新点。

Abstract This article discusses the gravitational potential energy-driven self-control with the direction of car design.Auto CAD applications and the institutions of the two-dimensional design of gears, Pro / EngineerWildfire 3.0 implementation Three-dimensional design of each part.

This work is based on the proposition contest theme of \car,\and proposed a \according to energy conversion principles, the design of a gravitational potential energy can be transformed into the mechanical energy to drive the car and walking devices. The first line their own car on the track set to automatically avoid obstacles (1 meter intervals, place a diameter of 20mm, 200mm flexible high barrier for the rod.) The greatest feature of this model is transformed into gravitational potential energy of the rotating gears, and then bonding according to the size of the gear wheel drive and steering wheel, and thus complete the task in accordance with the provisions of the route. This model will be carbon-free car design process, structural features such as described in detail and describes the innovative point of this work.

Keywords: Auto CAD Pro / EngineerWildfire carbon-free car Driving wheel Steering wheel Safe and efficient Convenient and flexible Innovative ideas
