本科學(xué)生畢業(yè)設(shè)計 電動記憶座椅 設(shè)計 院系 名稱 : 汽車 與交通 工程 學(xué)院 專業(yè)班級 : 車輛工程 學(xué)生姓名 : 指導(dǎo)教師 : 職 稱 : The Graduation Design for Bachelor39。s Degree Electtric Memory Seat Design Candidate: Zhang Xue hui Specialty: Vehicle Engineering Class: 07— 11 Supervisor: Yang Zhao Heilongjiang Institute of Technology I 摘 要 汽車座椅的設(shè)計主要以安全性和舒適性為主,并且隨著汽車工業(yè)和電子 技術(shù)的飛速發(fā)展,汽車座椅越來越舒適功能越來越齊全。本設(shè)計主要是 將電動座椅與車載電腦結(jié)合在一起, 可增加座椅的記憶功能,對座椅給中信息參數(shù)實現(xiàn)智能化管理。全電動調(diào)節(jié)的,前后,高低,靠背角度,前后傾斜,某些型號甚至有左右傾斜調(diào) 整,都是依靠座椅中電動機控制 ,你只要撥動幾個開關(guān)就能調(diào)節(jié)在這種電動座椅中加一個記憶芯片,當 調(diào)節(jié)到一個最舒適的位置時,這個位置就 可以 被記住了, 當 車被別人開過 時 ,座椅被重新調(diào)過, 只要上車后,座椅自動回到你當時設(shè)置的角度 。 汽車電動座椅自動控制系統(tǒng)的設(shè)計方法。系統(tǒng)以單片機為核心, 通過控制直流電動機,經(jīng)蝸輪蝸桿傳動機構(gòu)牽引座椅移動,使汽車座椅具有自動測量極限位置、手動調(diào)節(jié)、位置記憶以及自動恢復(fù)功能。該系統(tǒng)使汽車座椅便于安裝, 位置調(diào)節(jié)方便、快捷 。 關(guān)鍵詞 : 座椅 ; 設(shè)計 ; 記憶 ; 控制 II ABSTRACT Seat design mainly safety and fortable give priority to, and along with the auto industry and electronic technology rapid development, car seats more fortable function more and more plete. This design is mainly will electric seat and vehiclemounted puter together, can increase the seat of the memory function, to realize information in seat intellectualized control parameters. All electric adjustment, height, back of a chair, back and forth, back and forth, some tilt Angle of about even tilt adjustment type, all depend on seat, so long as you are in motor control switch can adjust turn several in the electric chair, add a memory chip when you adjust to a most fortable position, press memory button, the position is to remember, if the car was, seat is open others had to reset, then you just get on, press recall button, the seat of the automatic back to you when setting Angle. The electric memory seat of the automatic control system design method. System based on singlechip, through the control dc motivation, the worm gear and worm drive institutions traction, car seat seat move with automatic measurement limit position, manual adjustment, position memory and resume automatic function. This system makes car seats for easy installation, the position convenient adjustment, quickly. Key words: Seat。 Design。 Memory。 Control。 i 目 錄 摘要 ........................................................................................................................................
