Lub bumper pem hauv ntej ntawm lub tsheb yog dab tsi?
Lub bumper bumper pem hauv ntej (tseem hu ua lub bumper txhawb nqa lossis lub bracket tiv thaiv pem hauv ntej) yog ib qho tseem ceeb ntawm cov qauv uas txuas lub bumper pem hauv ntej ntawm lub tsheb rau lub cev lub cev, fender, lossis subframe. Nws feem ntau ua haujlwm xws li kev txhawb nqa, kev tso chaw, kev tiv thaiv, thiab kev nqus hluav taws xob. Lub luag haujlwm tseem ceeb
Kev txhawb nqa ruaj khov: Nruab lub bumper kom ruaj ntseg rau ntawm lub cev tsheb kom tiv thaiv kev co lossis kev tawg thaum tsav tsheb.
Kev Tiv Thaiv Kev Sib Tsoo: Hauv kev sib tsoo qeeb qeeb (xws li khawb lossis kev sib tsoo tom qab), nws deforms nws tus kheej kom nqus ib feem ntawm lub zog cuam tshuam, txo kev puas tsuaj rau cov khoom tseem ceeb xws li lub teeb taub hau, radar, thiab cov thoob dej.
Kev tso qhov chaw tseeb: Xyuas kom tseeb tias qhov sib txawv ntawm lub bumper thiab cov khoom nyob ib puag ncig xws li lub teeb taub hau thiab grilles yog sib npaug, zam kev suab tsis zoo lossis qhov sib txawv tsis sib xws.
Kev hloov kho ib puag ncig: Teb rau kev nthuav dav thiab kev sib cog lus ntawm thermal, kev co zaus siab, thiab lwm yam, los ntawm kev tso tawm kev ntxhov siab los ntawm cov clasps elastic lossis cov qhov sib txawv.
Cov yam ntxwv ntawm cov qauv thiab cov khoom siv
Cov Qauv: Feem ntau yog cov thav duab zoo li Z, snap-fit, lossis cov txheej txheem coj ua ke; qee qhov nrog cov khoom siv tiv thaiv kev rub rov qab thiab kev nias.
Cov ntaub ntawv siv ntau:
Cov hlau muaj zog heev: Xws li B340/590DP dual-phase steel, nrog lub zog tso zis ntawm 590 MPa;
Cov ntaub ntawv sib xyaw: Xws li cov iav fiber reinforced polyamide (GFPA6), nrog lub zog tensile ntawm 180 MPa thiab txo qhov hnyav ntawm 40%;
Cov yas engineering: Xws li hloov kho PA66, polypropylene txhawb nqa, sib npaug rigidity thiab toughness.
Txoj kev teeb tsa: Kho los ntawm bolts, snap-fit, lossis kev sib xyaw ua ke ntawm ob qho tib si; qee cov qauv siv cov qauv sib xyaw ua ke "snap-fit + bolt".
Kev txhim kho txuj ci thiab kev tsim kho tshiab (txij li xyoo 2026)
Kev txhim kho kev ua haujlwm ntawm kev sib dhos: Piv txwv li, Guangzhou Automobile daim ntawv pov thawj xyoo 2017 rau kev sib xyaw ua ke ntawm kev coj ua thiab kev tiv thaiv kev rub rov qab tau txhim kho kev ua haujlwm ntawm kev sib dhos los ntawm 30%;
Kev kho kom zoo dua qub: Keda daim ntawv pov thawj xyoo 2022 tau qhia txog lub tshuab hloov kho lub disc kom daws tau qhov teeb meem ntawm kev txau tshuaj sib xws;
Kev sib npaug ntawm qhov hnyav thiab kev nyab xeeb: General Motors '2024 patent tau ua kom lub kaum sab xis ntawm phab ntsa sab xis zoo dua rau 15 °, ua rau tus nqi nqus hluav taws xob ntawm kev sib tsoo nce ntxiv 25%;
Kev sib xws tshiab ntawm lub zog: Tsim cov yas thaiv hluav taws xob uas muaj kev rwb thaiv tsev siab (qhov ntim tsis kam > 10¹⁵ Ω·cm) kom ua tau raws li qhov yuav tsum tau ua kom muaj kev nyab xeeb ntawm hluav taws xob hluav taws xob siab.
Kev piav qhia txog cov lus
Lub bumper pem hauv ntej ≠ Lub thav duab bumper pem hauv ntej:
Lub bumper pem hauv ntej: Tsom ntsoov rau kev sib txuas thiab kev buffering, feem ntau yog cov khoom tsis yog lub luag haujlwm tseem ceeb;
Lub thav duab pem hauv ntej ntawm lub bumper (suav nrog lub teeb tseem ceeb, lub thawv nqus hluav taws xob): Yog lub qauv tseem ceeb uas nqa tau lub nra hnyav, koom nrog ncaj qha rau kev nqus hluav taws xob ntawm kev sib tsoo.
Feem ntau hu ua: Hauv cov ntsiab lus kho lossis hloov kho, nws kuj feem ntau hu ua "lub ntsej muag pem hauv ntej".
Cov lus qhia siv tau
Yog tias lub bracket laus lossis tawg, nws yuav ua rau lub bumper xoob, ua rau muaj suab tsis zoo, lossis txawm poob, cuam tshuam rau kev nyab xeeb tsav tsheb;
Thaum hloov, nws raug pom zoo kom siv cov khoom qub los yog cov khoom siv tom qab kho kom raug kom tsis txhob muaj qhov sib txawv, suab tsis zoo, lossis tsis ua haujlwm ntawm qhov snap-fit vim yog kev kam rau siab tsis sib xws;
Hauv kev hloov kho tawm ntawm txoj kev, lub bumper pem hauv ntej kuj yuav tsum tau ua kom tau raws li cov kev cai kho tshuab xws li kev tiv thaiv torsion sab, kev tiv thaiv longitudinal shear, thiab cua tsis kam; cov khoom siv pom zoo yog 6061-T6 txhuas alloy (lub zog tso zis 240 MPa);
Lub bumper bracket (tseem hu ua lub bumper bracket pem hauv ntej lossis lub bracket nruab nrab pem hauv ntej) yog ib qho tseem ceeb ntawm lub tsheb lub tsheb pem hauv ntej kev nyab xeeb, feem ntau ua haujlwm hauv peb yam: kev txhawb nqa, kev nqus zog, thiab kev sib txuas:
Kev Txhawb Nqa thiab Kev Kho: Raws li "lub moj khaum" ntawm lub bumper, lub bumper pem hauv ntej ua haujlwm ntawm kev txhawb nqa thiab kho lub rooj sib dhos bumper, xyuas kom meej tias nws ruaj khov thaum tsav tsheb, tiv thaiv kev co, kev hloov chaw, lossis suab tsis zoo, thiab xyuas kom meej tias qhov sib dhos raug thiab kev sib koom ua ke ntawm lub bumper thiab lub teeb pem hauv ntej, undergrates, thiab lwm yam;
Kev nqus zog ntawm kev sib tsoo: Hauv kev sib tsoo qeeb qeeb, lub bumper pem hauv ntej raug tswj hwm deformation los ntawm nws cov qauv (xws li thaj chaw tawg, kev nqus zog tawm, thiab lwm yam), nqus thiab faib cov zog cuam tshuam, txo cov zog xa mus rau lub tsheb cov kab ntev thiab chav neeg caij tsheb, yog li txo qhov kev puas tsuaj rau cov qauv tsheb thiab cov neeg nyob hauv;
Txuas lwm yam khoom: Lub bracket nruab nrab pem hauv ntej feem ntau ua haujlwm ua qhov chaw sib txuas, koom tes nrog cov khoom tseem ceeb xws li radiators, cov thoob dej, thiab lub teeb taub hau los kho lawv, xyuas kom meej tias qhov chaw ruaj khov ntawm cov khoom no thaum tsav tsheb thiab lav qhov kev ua haujlwm ib txwm ntawm lub tsheb;
Tsis tas li ntawd xwb, cov bumper bumper niaj hnub no kuj tseem ceeb rau kev ua kom lub cev sib dua, kev sib dhos ua ke, thiab kev ua haujlwm zoo hauv kev tsim qauv. Piv txwv li, cov qauv bracket sib cais tuaj yeem txo qhov hnyav, haum rau ntau yam duab, thiab txhim kho qhov tseeb ntawm kev teeb tsa los ntawm kev tsim qauv uas tsis ua yuam kev.
Qee cov thev naus laus zis patented kuj tau qhia txog cov qauv tshiab xws li snap-fit thiab multipoint positioning los txhim kho cov nqi tsim khoom thiab cov teebmeem pom.
Hauv kev xaus lus, txawm hais tias lub bumper pem hauv ntej tsis pom tseeb, nws ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb, kev ruaj khov thiab kev zoo nkauj.
