摘 要
本文主要為后車門門體及附件的設(shè)計(jì)。門體主要包括車門內(nèi)外板、加強(qiáng)橫梁、窗框等。車門附件主要包括車門鎖、鉸鏈、車門開度限位器、拉手操縱鈕、導(dǎo)軌、內(nèi)外裝配件、車門密封條等。在后面的設(shè)計(jì)中主要考慮這些零件設(shè)計(jì)以及車門上各種部件的布置、運(yùn)動不干涉等。
車門是車身結(jié)構(gòu)中一個(gè)較復(fù)雜的總成，熟悉車門結(jié)構(gòu)的功能要求、結(jié)構(gòu)特點(diǎn)和較正常的結(jié)構(gòu)處理方法是車門設(shè)計(jì)的基礎(chǔ)；另外，在具體的結(jié)構(gòu)設(shè)計(jì)過程中，正確的方法、步驟是實(shí)現(xiàn)合理設(shè)計(jì)的關(guān)鍵。如車門總體結(jié)構(gòu)的確定、附件的布置及運(yùn)動校核、結(jié)構(gòu)的統(tǒng)一協(xié)調(diào)和強(qiáng)度、剛度、可靠性、輕量化等方面都有一定的規(guī)律和要求。結(jié)合產(chǎn)品開發(fā)的具體實(shí)踐對車門結(jié)構(gòu)設(shè)計(jì)的幾個(gè)問題做了較詳細(xì)的論述。

ABSTRACT
The main body of a book is experienced and observed mainly for queen vehicle reaching the accessories design. The door body includes car door inside and outside board 、 reinforces crossbeam、 window case etc. Car door accessories includes the car door lock 、 the hinge mainly 、the position-limitimplement of car door aperture、 the handle control Niu、 slide way、 inside and outside assemble document 、car door hermetic sealing strip etc. Arrangement , motion noninterference thinking that these parts design and the car door fixes the various component mainly in back design etc.
Car door is more complex assembly is the body structure. Structural function requirement, specialty of structure and general handling method of structure are the basis of body door structure design. In the course of door structural design, correct method and procedure are the key points to realize design, such as determination of door structure outlay, arrangement of accessories, motion verification and also others as overall coordination of structure, strength, rigidity, reliability etc, all have definite rule and demand. Fairly detailed discussion is made for some problems of door structural design combining the substantial practice of product development.
