摘要
随着科技和社会的发展和进步,各种各样的车辆将会陆续出现在公路上面,与此同时,随着时间的推移,汽车之间发生的交通事故也越来越频繁,如果不对汽车进行检修,最基本的就是严重影响了汽车的外观,严重的导致汽车不能继续使用,在以前,我国对这种现状的重视程度还是不够,即在交通工具上有自带的检修工具,但这对于难度大点的检修工作就带来困难,例如车底盘,如果发生故障,根本就不能够检修,而且这种现状存在着许多不和谐因素,更使群体分化加剧,社会人文关怀程度的下降。而如果能够经常对汽车进行检修,将会大大提高汽车的使用年限和外观美,给人们一个安全、放心的驾驶环境。
本次设计是关于汽车检修升降台架的设计,通过对传统的汽车检修升降台架结构进行了改进和优化,对它的机械结构和液压系统进行设计,使得此种类型的汽车检修升降台架的使用范围更广泛,更加灵活,并且对今后的选型设计工作有一定的参考价值。

Abstract
For a lot of special places, like the risk is very big, or we are difficult to reach, such as disarm bombs, unknown corresponding domains such as detection, probing deep of more dangerous situation usually need to implement the robot.It’s a main part of robot for micro pedipulator, walking robots and more than six feet, compared to the Eight Legged Robot, because of strong bearing capacity, good stability, which the meritss is simple construction, So, a large number of researchers around the world, start .This paper mainly to the four bar mechanism as the main execution elements to design of micro walking the whole scheme of the four bar mechanism.
Its principle is diagonal synchronization, leg activity by the structure of the crank rocker, front leg movements around the same, it detailed performance curve characteristics of the connecting rod,when the curve trajectory diagonal straight line segment, the robot is stationary, the motion trajectory when the diagonal curve is slanting line do the walking.
