摘 要:后圍出風口總成一般布置在車倆后部活側(cè)圍鈑金上,并在出風口的骨架處設(shè)置2~5個葉片,每個葉片都有自己的獨立翻轉(zhuǎn)機構(gòu),在車門關(guān)閉時因車廂內(nèi)瞬間擠入大量空氣,氣壓暴漲推動葉片向上翻起打開出風口及時泄壓,在減輕乘坐人員不適感的同時,也具備了對車廂內(nèi)換氣、通風的功能。

Design Requirements for Rear Air Outlet Assembly
Li Shuai
Abstract:The rear wall air outlet assembly is generally arranged on the sheet metal of the live side wall at the rear of the car, and 2~5 blades are set at the skeleton of the air outlet. Each blade has its own independent turning mechanism. When the door is closed as a large amount of air is squeezed into the cabin instantly, the air pressure surge pushes the blades upward to open the air outlet to release the pressure in time, which not only relieves the discomfort of passengers, but also has the function of ventilation in the cabin.
Key words:air outlet body, sealing ring, blade, bead, clip, welding column

后圍出風口總成屬于外飾塑料小件,結(jié)構(gòu)輕巧,但功能及其重要,設(shè)計階段既要考慮車廂容積和壓入的空氣量保證開口尺寸,同時也要避免因結(jié)構(gòu)設(shè)計不合理,在葉片翻起時,在出風口處形成的渦流使雜質(zhì)、灰塵等進入車廂內(nèi)部,降低乘坐人員的舒適性。(剩余3159字)
