Guhitamo Impeta Yukuri ya Kamera ya Automotive Kamera Modules: Ubuyobozi Bwuzuye Kubisobanuro

Nka "jisho" rya sisitemu igezweho yo gufasha abashoferi (ADAS) hamwe na porogaramu yigenga yo gutwara, moderi ya kamera yimodoka ningirakamaro kumutekano wibinyabiziga. Ubusugire bwiyi sisitemu yicyerekezo bushingiye cyane kubushobozi bwabo bwo guhangana n’ibidukikije bikaze. Gufunga impeta, nkibikoresho byingenzi birinda, bigira uruhare runini mugukora neza mugutanga umukungugu, ubushuhe, kunyeganyega, nubushyuhe bukabije. Guhitamo ikidodo gikwiye nibyingenzi kubwigihe kirekire. Aka gatabo karasobanura neza ibyingenzi - ibikoresho, ingano, n'ibipimo ngenderwaho - kugirango umenyeshe inzira yo gutoranya ibinyabiziga bifunga kamera.

1. Ibisobanuro by'ibikoresho: Urufatiro rwo gushiraho ikimenyetso

Guhitamo elastomer byerekana neza kashe irwanya ubushyuhe, imiti, no gusaza. Ibikoresho bikunze kugaragara kuri kamera yimodoka zirimo:

• Nitrile Rubber (NBR): Azwiho kurwanya cyane amavuta n'ibikomoka kuri peteroli, hamwe no kurwanya abrasion. NBR ni amahitamo ahendutse kubisabwa mubice bya moteri cyangwa uduce twerekanwe namavuta. Ubukomere busanzwe buri hagati ya 60 na 90 Inkombe A.
• Rubic Silicone (VMQ): Itanga ubushyuhe budasanzwe bwo gukora (hafi -60 ° C kugeza + 225 ° C) mugihe gikomeza guhinduka. Kurwanya ozone hamwe nikirere bituma iba ibikoresho byatoranijwe kuri kamera yo hanze yerekana urumuri rwizuba hamwe nubushyuhe bwibidukikije.
• Fluoroelastomer (FKM): Itanga imbaraga zo guhangana nubushyuhe bwo hejuru (kugeza kuri + 200 ° C no hejuru), ibicanwa, amavuta, hamwe n’imiti myinshi ikaze. FKM ikunze gusobanurwa kubidodo hafi ya powertrain cyangwa mubushuhe bwinshi kandi bushobora guterwa nubushakashatsi bwibinyabiziga byamashanyarazi (EV) bipakira. Gukomera bisanzwe ni hagati ya 70 na 85 Inkombe A.

Impanuro yo guhitamo: Ibidukikije bikora nubushoferi bwibanze bwo guhitamo ibikoresho. Reba ubushyuhe bukomeza kandi bukenewe cyane, kimwe no guhura n'amazi, ibikoresho byoza, cyangwa umunyu wo mumuhanda.

2. Ibipimo by'ibipimo: Kwemeza neza neza

Ikidodo kirakora gusa niba gihuye neza na kamera. Ibipimo byingenzi byingenzi bigomba guhuzwa neza nigishushanyo mbonera:

• Imbere ya Diameter (ID): Igomba guhuza neza na barri ya lens cyangwa diameter ya groove diameter. Ubworoherane busanzwe bukomeye, akenshi muri mm 0,10 mm, kugirango hirindwe icyuho gishobora guhungabanya kashe.
• Igice cyambukiranya (CS): Iyi diameter yumugozi wa kashe igira ingaruka itaziguye imbaraga zo kwikuramo. Ibice bisanzwe byambukiranya kuva kuri 1.0 mm kugeza kuri mm 3.0 kuri kamera nto. CS ikwiye itanga compression ihagije idateye guhangayika cyane bishobora gutera kunanirwa imburagihe.
• Kwiyunvira: Ikidodo kigomba kuba cyarakozwe kugirango kigabanuke ku ijanisha ryihariye (mubisanzwe 15-30%) muri glande. Uku kwikuramo gukora igitutu gikenewe cyo guhuza inzitizi nziza. Kwikuramo munsi biganisha kumeneka, mugihe gukabya gukabije bishobora gutera gusohora, guterana hejuru, no gusaza byihuse.

Kubyububiko butari busanzwe bwa geometrike, kashe-yashizweho kashe ifite ibishushanyo byihariye byiminwa (urugero, U-igikombe, D-shusho, cyangwa imyirondoro igoye) irahari. Gutanga abatanga ibishushanyo mbonera 2D cyangwa 3D CAD yerekana ni ngombwa kuriyi porogaramu.

3. Imikorere no kubahiriza: Kuzuza ibipimo nganda byimodoka

Ikidodo c'ibinyabiziga kigomba kwihanganira ibizamini byemewe kugirango bizere kwizerwa mubuzima bwikinyabiziga. Ibipimo ngenderwaho byingenzi byerekana:

• Ubushyuhe bwo Kurwanya Ubushyuhe: Ikidodo kigomba kwihanganira gusiganwa ku magare yagutse (urugero, -40 ° C kugeza kuri + 85 ° C cyangwa irenga kubisabwa munsi ya hood) kubihumbi byizunguruka bitavunitse, bikomye, cyangwa bigahinduka burundu.
• Kurinda Ingress (IP Rating): Ikidodo ningirakamaro kugirango ugere kuri IP6K7 (umukungugu wuzuye) hamwe na IP6K9K (umuvuduko ukabije / gusukura ibyuka). Kurohama, IP67 (metero 1 kuminota 30) na IP68 (kwibira byimbitse / birebire) ni intego rusange, bigenzurwa nikizamini gikomeye.
• Kuramba no Gusenyuka: Nyuma yo gukorerwa igihe kirekire no guhangayika (bigereranywa nibizamini nkamasaha 1.000 hejuru yubushyuhe bwo hejuru), kashe igomba kwerekana compression yo hasi. Igipimo cyo gukira cya> 80% nyuma yo kwipimisha cyerekana ibikoresho bizakomeza imbaraga za kashe mugihe.
• Kurwanya Ibidukikije: Kurwanya ozone (ASTM D1149), imirasire ya UV, nubushuhe nibisanzwe. Ihuzwa n’amazi yimodoka (feri ya feri, coolant, nibindi) nayo iragenzurwa.
• Impamyabushobozi yimodoka: Ababikora bakora muri sisitemu yo gucunga ubuziranenge bwa IATF 16949 berekana ubwitange mubikorwa bigoye bisabwa murwego rwo gutanga amamodoka.

Umwanzuro: Uburyo butunganijwe bwo guhitamo

Guhitamo impeta nziza yo gufunga ni icyemezo cyingirakamaro kiringaniza ibisabwa, ibibazo by ibidukikije, nigiciro. Mbere yo kurangiza guhitamo, sobanura neza urwego rwubushyuhe bukora, imiterere yimiti, imbogamizi zumwanya, hamwe nibisabwa byinganda.

Mugihe ikintu gito, impeta yo gufunga ni umusanzu wibanze mumutekano no mumikorere ya sisitemu yo kureba ibinyabiziga bigezweho. Uburyo bwuburyo bwo gusobanura bwerekana ko "amaso" yikinyabiziga aguma asobanutse kandi yizewe, kilometero nyuma y'ibirometero. Gufatanya nu mutanga wujuje ibyangombwa utanga amakuru akomeye ya tekiniki hamwe ninkunga yo kwemeza ni urufunguzo rwo gutsinda.
