摘 要
窗簾是家庭、展覽館、影院、賓館、會議室、辦公室等場合的必備品，但這些場合使用的窗簾基本上是普通的手動窗簾，使用電機驅動的很少見。究其原因，主要是現有的電動窗簾大多是由旋轉電機來驅動的，窗簾開合需要一套減速及傳動機構，把電機的旋轉運動轉變為直線運動，這就必然使窗簾架的結構復雜，故障率高，普及受到限制。
直流直線電機自動窗簾是一種利用直線電機直接直線驅動窗簾運行，從而達到自動控制窗簾狀態的一種遮陽設備，作為汽車內飾它不但增加了行車舒適度，而且保護了乘客隱私，實現單向透視以外，此外他還可以隔熱、阻擋紫外線。無形的增加了駕駛的安全性。有研究表明，在陽光照射下，如果汽車內部溫度由25攝氏讀增加到35攝氏度，駕駛者的反應速度將下降20%，因此，汽車窗簾對調節車內溫度，提高駕駛安全性起到重要作用。各種汽車自動窗簾自投放市場以來，非常受到用戶青睞。隨著中國汽車產業的快速發展，汽車窗簾在國內的發展將會有非常明朗的前景。
本文研究工作針對對直流直線電機驅動式窗簾設計過程中碰到的主要問題的解決和電機與導軌的一體化設計方案，主要包括以下幾個部分：第一章為緒論，著重分析了選題背景和意義，包括本直線電機的性能和優勢，以及國內外研究現狀。第二章對直流直線電機驅動式窗簾工作原理、結構和基本工作特性進行了大致的介紹第三章為本課題的主體部分，即完成直流直線電機驅動式窗簾設計和搭建，先概述汽車自動窗簾的方案，然后對直流直線電機驅動式窗簾的整體結構設計。

A Design of DC Linear Electric Curtain
Abstract
Curtain is the essential goods for family, exhibition halls, cinemas, hotels, conference rooms, offices and other places.,but these occasionscurtain basically use ordinary curtains,using, motor-driven lessly. The reason is mainly that curtain of motor-driven requair a set of s.low down and drive mechanism.for the motor’s rotary motion into linear motion ,which must make high failure rate and the structure of complex.So its spread is limited.
DC linear motor auto curtain is drived by linear motor ,so as to achieve a state of automatic controling, it can protect passengers in addition to privacy, to achieve a one-way Perspective, in addition to heat insulation and block UV rays. Some research shows that in sunlight, driving the response rate will drop 20 percent, so the car curtains inside temperature regulation and improve driving safety play an important role in . With the rapid development of China's automobile industry, car curtains in the country's development will have a very uncertain future..
This paper aimed to solve the main problems med in design and integration of motor and rail design.The first chapter for the introduction will focus on analyzing the context and meaning of topics, including the automatic car curtain performance and advantages, as well as domestic and foreign research the status quo.
Chapter II of the DC linear motor driven curtain principle, the basic structure and characteristics of the work.
Chapter III of this part is the main topics, namely Automatic curtains completed the design and structures, first outlined the programme of Automatic curtains, and then the DC linear motor driven curtain automatic curtains and the various details of the overall design.
Keywords: Comfort Privacy Prospect The DC linear motor curtain
