前門外飾板簡介

汽車的車門下部外飾板(ban)是通過卡(ka)扣與鈑金(jin)件卡(ka)接在一起,外飾板(ban)的邊緣位置與鈑金(jin)貼合,通過雙面膠粘接固定。

汽車前圍板作用：

1、汽(qi)車(che)(che)覆(fu)(fu)蓋(gai)(gai)件（簡稱覆(fu)(fu)蓋(gai)(gai)件）是(shi)指構(gou)成汽(qi)車(che)(che)車(che)(che)身或駕駛(shi)室、覆(fu)(fu)蓋(gai)(gai)發(fa)動機(ji)和(he)底盤的(de)異(yi)形體表(biao)面和(he)內部的(de)汽(qi)車(che)(che)零件。汽(qi)車(che)(che)覆(fu)(fu)蓋(gai)(gai)件既是(shi)外觀裝飾性(xing)的(de)零件，又是(shi)封(feng)閉薄殼狀的(de)受力零件；
2、覆(fu)蓋(gai)件表面(mian)上任何微小的(de)(de)缺(que)陷(xian)都會在涂漆后(hou)引(yin)起光線的(de)(de)漫反射而(er)損壞外(wai)形的(de)(de)美觀，因(yin)此覆(fu)蓋(gai)件表面(mian)不允許(xu)有波紋、皺折、邊緣(yuan)拉痕(hen)和其他(ta)破(po)壞表面(mian)美感的(de)(de)缺(que)陷(xian)。歐、美、日(ri)等發達國家生產的(de)(de)A級表面(mian)精(jing)度(du)的(de)(de)汽車覆(fu)蓋(gai)件有引(yin)擎蓋(gai)板；
3、車頂蓋(gai)(gai)(gai)，左(zuo)(zuo)、右車側(ce)圍(wei)(wei)(wei)(wei)，前(qian)(qian)(qian)(qian)、后(hou)車門，前(qian)(qian)(qian)(qian)、后(hou)、左(zuo)(zuo)、右翼(yi)子(zi)板(ban)(ban)(ban)(ban)(ban)，行禮箱蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)，發(fa)動(dong)(dong)機(ji)前(qian)(qian)(qian)(qian)支撐板(ban)(ban)(ban)(ban)(ban)，發(fa)動(dong)(dong)機(ji)前(qian)(qian)(qian)(qian)裙(qun)板(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)(qian)圍(wei)(wei)(wei)(wei)上蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)，后(hou)圍(wei)(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)，后(hou)圍(wei)(wei)(wei)(wei)上蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)(qian)裙(qun)板(ban)(ban)(ban)(ban)(ban)，前(qian)(qian)(qian)(qian)框架，前(qian)(qian)(qian)(qian)翼(yi)子(zi)板(ban)(ban)(ban)(ban)(ban)，車輪(lun)擋(dang)泥(ni)板(ban)(ban)(ban)(ban)(ban)、后(hou)翼(yi)子(zi)板(ban)(ban)(ban)(ban)(ban)、后(hou)圍(wei)(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)、行李倉蓋(gai)(gai)(gai)，后(hou)圍(wei)(wei)(wei)(wei)上蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)、頂蓋(gai)(gai)(gai)、前(qian)(qian)(qian)(qian)圍(wei)(wei)(wei)(wei)側(ce)板(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)(qian)圍(wei)(wei)(wei)(wei)板(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)(qian)圍(wei)(wei)(wei)(wei)上蓋(gai)(gai)(gai)板(ban)(ban)(ban)(ban)(ban)、前(qian)(qian)(qian)(qian)擋(dang)泥(ni)板(ban)(ban)(ban)(ban)(ban)、發(fa)動(dong)(dong)機(ji)罩。覆蓋(gai)(gai)(gai)件(jian)的制造(zao)是汽車車身制造(zao)的關鍵環(huan)節。
前(qian)(qian)圍(wei)(wei)(wei)板是(shi)指發動機(ji)艙(cang)與(yu)車廂之(zhi)間的(de)隔(ge)板，它和地板、前(qian)(qian)立柱聯接(jie)，安(an)裝(zhuang)在前(qian)(qian)圍(wei)(wei)(wei)上(shang)蓋板之(zhi)下。前(qian)(qian)圍(wei)(wei)(wei)板上(shang)有許(xu)多(duo)孔口，作為操縱(zong)用(yong)的(de)拉線、拉桿、管路和電線束通過之(zhi)用(yong)，還(huan)要(yao)配合踏板、方向機(ji)柱等機(ji)件安(an)裝(zhuang)位置(zhi)。為防止發動機(ji)艙(cang)里(li)的(de)廢氣、高溫、噪聲竄入(ru)車廂，前(qian)(qian)圍(wei)(wei)(wei)板上(shang)要(yao)有密(mi)(mi)封措施和隔(ge)熱(re)裝(zhuang)置(zhi)。在發生(sheng)意外事(shi)故時，它應具有足(zu)夠的(de)強(qiang)度和剛度。對比車身其它部件而言，前(qian)(qian)圍(wei)(wei)(wei)板裝(zhuang)配最重要(yao)的(de)工(gong)藝技(ji)術是(shi)密(mi)(mi)封和隔(ge)熱(re)，它的(de)優劣往往反映(ying)了車輛運行的(de)質量。
