Lub Tsheb Bumper yog dab tsi?

Tsheb bumpers yog ib qho tseem ceeb ntawm kev ruaj ntseg cov cuab yeej ntsia rau pem hauv ntej thiab nram qab lub tsheb. Nws lub luag haujlwm tseem ceeb yog txhawm rau nqus kev sib tsoo lub zog, tiv thaiv cov qauv tsheb thiab kev nyab xeeb ntawm cov neeg taug kev, thiab ua haujlwm rau kev ua kom zoo dua qub thiab ua kom zoo nkauj. Cov ntsiab lus ntawm lawv cov qauv, kev ua haujlwm, cov ntaub ntawv, tsim evolution thiab txij nkawm yog raws li nram no:
I. Cov Txheej Txheem Txheej Txheem
** Sab nrauv phaj (lub plhaub sab nraud):** nthuav tawm ncaj qha, feem ntau yog ua los ntawm cov yas (xws li polypropylene PP), nrog rau txheej txheej kom phim lub tsheb xim.
* ** Yam ntxwv los ntawm cov qauv cushioning (xws li ripples lossis grooves) **, lub zog yog absorbed los ntawm deformation nyob rau hauv me me kev sib tsoo.
* ** Cushioning Material: ** Nyob nruab nrab ntawm lub phaj sab nrauv thiab kab teeb, nws feem ntau yog ua los ntawm foamed polypropylene (EPP) los yog honeycomb aluminium kom nqus tau cov kev sib tsoo ntxiv.
* **Qee cov qauv siab- kawg ua rau lub zog deformable- nqus cov blocks uas tuaj yeem kho tau sai nrog cov khoom hloov pauv tom qab qis - kev sib tsoo ceev.
**Crossbeam (Bumper Beam):** Muab zais rau hauv lub bumper yog ib qho tseem ceeb load-cov kabmob qauv, feem ntau yog ua los ntawm siab- lub zog steel (xws li boron steel) lossis aluminium alloy.
* * _ yam ntxwv, nyob rau hauv siab - kev sib tsoo ceev, folds ** disperse zog los ntawm orderly deformation, txo intrusion rau hauv cov neeg nrog caij compartment.
** Txuas txuas:** Ruaj lub bumper rau lub thav duab nrog lub zog txaus los cuam tshuam thaum tiv thaiv kev tawg thiab tawg.
** II. Core Functions: **
** Kev tiv thaiv neeg taug kev: ** Lub pem hauv ntej bumper sab nrauv phaj yog ua los ntawm cov yas mos kom txo tau cov ceg raug mob rau cov neeg taug kev hauv kev sib tsoo.
Qee cov qauv tau nruab nrog lub hood pop-up thev naus laus zis, uas txhawb nqa lub hood qhov siab thiab ua kom tsis muaj chaw rau cov neeg taug kev hauv kev sib tsoo.
** Tsawg-Kev Tiv Thaiv Kev Sib Tw Ceev:** Kev nqus lub zog qis dua 15 km / h, tiv thaiv kev puas tsuaj rau lub cev vaj huam sib luag thiab txo cov nqi kho.
Piv txwv li, ib qho me ntsis txhuam tawm tsam qhov cuam tshuam thaum thim rov qab hauv qhov chaw nres tsheb yuav xav tau tsuas yog hloov lub vaj huam sib luag sab nrauv, tsis yog kho tag nrho lub cev.
**High-Speed ​​Collision Energy Management:** Ua hauj lwm nrog cov kab ntev ntawm lub tsheb, qhov kev cuam tshuam yog kis thoob plaws hauv lub tsheb qauv los ntawm lub zog nqus ntawm cov quav, tiv thaiv kev ncaj ncees ntawm cov neeg caij tsheb.
** Cov qauv xeem:** Ua tau raws li C-NCAP lossis Euro NCAP kev sib tsoo (piv txwv li, 50 km / h frontal collision).
**Aerodynamic Optimization:** Lub deflector yog tsim nyob rau hauv lub bumper kom txo tau airflow turbulence, txo luag coefficient (Cd nqi), thiab txhim kho roj kev lag luam. Tesla Model 3, piv txwv li, txo nws cov Cd rau 0.23 los ntawm kev ua kom zoo dua nws cov qauv tsim, txo qis kev siv zog.
III. Khoom Evolution
Lub caij nyoog|Cov khoom tseem ceeb|Yam ntxwv
Thaum ntxov|Hlau (Steel / Aluminium Alloy)|Lub zog siab tab sis lub teeb yuag, yooj yim los tswj, corrosive
Yas (Polypropylene PP) los ntawm xyoo 1980s poob 30% -50% nws qhov hnyav, yog corrosion resistant thiab tuaj yeem tsim los coj cov duab nyuaj, tab sis tsis tshua muaj kev cuam tshuam.
Ncej -2000|Composites (PP + EPDM-TD)|Ntxiv cov roj hmab hais los txhim kho toughness thiab cuam tshuam tsis kam thaum tuav lub teeb
Hyundai|Carbon Fiber reinforced plastics|Haum rau siab -kev ua tau zoo, lub teeb yuag, ruaj khov tab sis kim tsheb xws li Porsche 911 GT3
IV. INTRODUCTION INTRODUCTION Tsim Trends
Kev koom ua ke|Bumper tsim nrog grille, pos huab teeb, radar, thiab lwm yam., txo cov naj npawb ntawm cov khoom thiab txhim kho kev sib dhos ua haujlwm.
Audi yog txhua yam -hauv- ib qho kev noj zaub mov, piv txwv li, sib txuas nrog lub bumper, boosting brand recognition.
Kev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb: ua tau -hauv millimeter-wave radar, lub koob yees duab thiab lwm yam sensors, txhawb kev hloov kho Adaptive Cruise Control, Tsis siv neeg nres thaum muaj xwm ceev thiab lwm yam haujlwm.
Kev Sib Tw: Qhov teeb meem ntawm cov yas jamming radar teeb liab yuav tsum muaj cov txheej txheem tshwj xeeb lossis cov khoom siv.
Cov ntaub ntawv siv tau ruaj khov: Qee cov tuam txhab lag luam siv cov khoom siv rov ua dua tshiab, xws li PET lub raj mis los ntawm dej hiav txwv, los tsim cov buffers los txo lawv qhov cuam tshuam rau ib puag ncig.
Piv txwv li Ford F-150's bumper sab nrauv, siv 20% cov yas siv dua tshiab, txo cov pa roj carbon monoxide.
