過(guo)(guo)(guo)去的傳統卷簾(lian)門(men)(men)(men)(men)存(cun)在(zai)以下(xia)不足，門(men)(men)(men)(men)體一(yi)般由(you)若(ruo)干的門(men)(men)(men)(men)片呈(cheng)波浪型折疊(die)而(er)(er)成，由(you)于門(men)(men)(men)(men)體啟閉過(guo)(guo)(guo)程(cheng)(cheng)中(zhong)，相鄰的門(men)(men)(men)(men)片會(hui)相對折疊(die)或(huo)(huo)伸展，從而(er)(er)使得門(men)(men)(men)(men)體的寬(kuan)度(du)發生(sheng)變(bian)化(hua)，但是(shi)這過(guo)(guo)(guo)程(cheng)(cheng)中(zhong)，門(men)(men)(men)(men)洞上(shang)的滑槽(cao)的寬(kuan)度(du)是(shi)不變(bian)的，從而(er)(er)使得卷簾(lian)門(men)(men)(men)(men)在(zai)卷起或(huo)(huo)放下(xia)的過(guo)(guo)(guo)程(cheng)(cheng)中(zhong)，由(you)于門(men)(men)(men)(men)片晃動會(hui)產生(sheng)較(jiao)大的噪(zao)音;我們不妨試(shi)試(shi)快(kuai)(kuai)速(su)卷簾(lian)門(men)(men)(men)(men)，快(kuai)(kuai)速(su)卷簾(lian)門(men)(men)(men)(men)就沒有噪(zao)音了(le)?是(shi)因為什么?

  那是因為(wei)，能降(jiang)(jiang)噪的(de)(de)(de)快(kuai)速(su)卷簾門(men)(men)(men)(men)在墻體上設置有(you)門(men)(men)(men)(men)洞，門(men)(men)(men)(men)洞的(de)(de)(de)兩側(ce)設置有(you)供門(men)(men)(men)(men)體上下(xia)升(sheng)降(jiang)(jiang)的(de)(de)(de)凹槽(cao)，凹槽(cao)內兩側(ce)壁設置有(you)氣囊，氣囊的(de)(de)(de)外(wai)側(ce)設置有(you)防(fang)護(hu)(hu)板(ban)(ban)，兩個防(fang)護(hu)(hu)板(ban)(ban)之間形成(cheng)用于夾持門(men)(men)(men)(men)體且供門(men)(men)(men)(men)體上下(xia)滑移的(de)(de)(de)滑槽(cao)。門(men)(men)(men)(men)體向(xiang)(xiang)上運(yun)動(dong)(dong)時(shi)，相(xiang)鄰兩個門(men)(men)(men)(men)片(pian)(pian)(pian)由(you)于擠(ji)壓折疊使得(de)門(men)(men)(men)(men)體的(de)(de)(de)寬度(du)增加(jia)，門(men)(men)(men)(men)片(pian)(pian)(pian)向(xiang)(xiang)外(wai)擠(ji)壓防(fang)護(hu)(hu)板(ban)(ban)，防(fang)護(hu)(hu)板(ban)(ban)相(xiang)外(wai)擠(ji)壓氣囊，使得(de)防(fang)護(hu)(hu)板(ban)(ban)與門(men)(men)(men)(men)片(pian)(pian)(pian)始終保持緊(jin)貼(tie)狀態，使得(de)門(men)(men)(men)(men)片(pian)(pian)(pian)和防(fang)護(hu)(hu)板(ban)(ban)之間因存(cun)在間隙很小不會碰撞產(chan)生噪音或者噪音很小，門(men)(men)(men)(men)體向(xiang)(xiang)下(xia)運(yun)動(dong)(dong)時(shi)，相(xiang)鄰兩個門(men)(men)(men)(men)片(pian)(pian)(pian)伸展使得(de)門(men)(men)(men)(men)體的(de)(de)(de)寬度(du)減小，氣囊在彈性作用下(xia)推動(dong)(dong)防(fang)護(hu)(hu)板(ban)(ban)，使得(de)防(fang)護(hu)(hu)板(ban)(ban)緊(jin)貼(tie)門(men)(men)(men)(men)片(pian)(pian)(pian)，同樣(yang)起到減少噪音的(de)(de)(de)效果。

  氣囊(nang)(nang)(nang)(nang)上設(she)置(zhi)有(you)(you)氣嘴(zui)，氣嘴(zui)穿(chuan)出墻體(ti)(ti)外。通過采用(yong)上述技術方案，便于(yu)對氣囊(nang)(nang)(nang)(nang)進行充氣或放氣。防(fang)護(hu)板呈(cheng)L型(xing)，一(yi)側(ce)(ce)貼(tie)合于(yu)氣囊(nang)(nang)(nang)(nang)與門(men)體(ti)(ti)之(zhi)間(jian)，另一(yi)側(ce)(ce)伸出凹(ao)槽(cao)(cao)外位于(yu)門(men)洞(dong)的(de)(de)(de)兩(liang)側(ce)(ce)。一(yi)方面(mian)能夠(gou)對氣囊(nang)(nang)(nang)(nang)起到保(bao)護(hu)作用(yong)，另一(yi)方面(mian)，能夠(gou)對氣囊(nang)(nang)(nang)(nang)的(de)(de)(de)形變起到導向(xiang)輔(fu)助作用(yong)。凹(ao)槽(cao)(cao)的(de)(de)(de)內(nei)側(ce)(ce)壁設(she)置(zhi)有(you)(you)限位槽(cao)(cao)，氣囊(nang)(nang)(nang)(nang)的(de)(de)(de)一(yi)側(ce)(ce)粘接于(yu)限位槽(cao)(cao)內(nei)。使得氣囊(nang)(nang)(nang)(nang)在(zai)凹(ao)槽(cao)(cao)內(nei)更加穩定(ding)。門(men)體(ti)(ti)沿(yan)其長度方向(xiang)均布有(you)(you)若干(gan)橡膠制成的(de)(de)(de)隔片。在(zai)門(men)體(ti)(ti)收卷的(de)(de)(de)過程中，避免金屬的(de)(de)(de)門(men)片之(zhi)間(jian)摩擦產生(sheng)噪音。
