摘 要
本文主要為后車門門體及附件的設計。門體主要包括車門內外板、加強橫梁、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、導軌、內外裝配件、車門密封條等。在后面的設計中主要考慮這些零件設計以及車門上各種部件的布置、運動不干涉等。
車門是車身結構中一個較復雜的總成，熟悉車門結構的功能要求、結構特點和較正常的結構處理方法是車門設計的基礎；另外，在具體的結構設計過程中，正確的方法、步驟是實現(xiàn)合理設計的關鍵。如車門總體結構的確定、附件的布置及運動校核、結構的統(tǒng)一協(xié)調和強度、剛度、可靠性、輕量化等方面都有一定的規(guī)律和要求。結合產(chǎn)品開發(fā)的具體實踐對車門結構設計的幾個問題做了較詳細的論述。

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.
