公交车车门开关的模块化设计

Modular Design for Bus Door Switch

在简述了汽车模块化技术的基础上,以模块化产品设计的原理,就公交车车门开关存在的缺陷进行模块化的设计。本项设计可以实现以下功能:1)正常的车门开与关;2)车辆在紧急事故发生时的自动与手动打开;3)延时电路带来的车门关门失效。在以上功能都失灵后乘员也可手动推开车门。设计中将上述功能电路制成模块电路板,同时增加一应急电源和应急气道,大大提高车门的安全性与应急性。

This article introduces the auto modular technology,then makes modular design according to the principle of modular product design and the characteristics of bus door switch.This design has the following functions：1.open and shut the door normally;2.open the door automatically or manually when the accident happens;3.prevent the door from closing failure by the time-lapse circuit.When the above two functions are failed,passengers can also open the door manually.In the design,the functional circuits are made into module circuit,and the emergency power and airway can also be increased to improve the safety and emergency of car greatly.
