Kana zvasvika pakuchaja muhupenyu, yako yekutanga kuita ndeye kushandisa charger uye tambo yekuchaja.Mumakore achangopfuura, nhamba ye "wireless chargers" yave iri pamusika, iyo inogona kubhadharwa "mumhepo".Ndeapi misimboti uye matekinoroji anoshandiswa mune izvi?
Kare muna 1899, nyanzvi yefizikisi Nikola Tesla akatanga tsvakiridzo yake yekufambiswa kwemagetsi isina waya.Akavaka shongwe yemagetsi isina waya muNew York, uye akabata nzira yekutumira magetsi isina waya: kushandisa pasi seyemukati conductor uye ionosphere yepasi seyekunze conductor, nekukudza iyo inotumira muradial electromagnetic wave oscillation mode, yakagadzwa pakati. pasi neinosphere Inorira pamhepo yakaderera ingangoita 8Hz, uye yobva yashandisa mafungu emagetsi epamusoro anotenderedza pasi kufambisa simba.
Kunyangwe pfungwa iyi isina kuitika panguva iyoyo, kwaive kuongorora kwakashinga kwekuchaja pasina waya nemasayendisiti makore zana apfuura.Mazuva ano, vanhu vakaramba vachitsvaga uye kuyedza pane izvi, uye vakabudirira kugadzira tekinoroji yekuchaja isina waya.Pfungwa yepakutanga yesainzi iri kuitwa zvishoma nezvishoma.
Wireless kuchaja tekinoroji inoshandisa nzira isiri-yemuviri yekubata kuti uwane kufambisa kwemagetsi.Parizvino, kune matatu akajairwa asina waya magetsi ekufambisa matekinoroji, anoti electromagnetic induction, electromagnetic resonance, uye masaisai eredhiyo.Pakati pavo, iyo electromagnetic induction mhando inzira inoshandiswa zvakanyanya, iyo isingangove nepamusoro yekuchaja kugona, asiwo ine mutengo wakaderera.
Musimboti wekushanda we electromagnetic induction isina waya yekuchaja tekinoroji ndeiyi: isa coil yekutumira pane isina waya yekuchaja base, uye isa coil yekugamuchira kuseri kwenhare mbozha.Kana nhare mbozha ichichajwa padyo nebhesi yekuchaja, iyo coil yekutumira inoburitsa inochinjika magineti nekuti yakabatana kune inochinjika ikozvino.Shanduko yesimba remagineti ichaita kuti magetsi apinde mucoil yekugamuchira, nokudaro achiendesa simba kubva kumagumo ekutumira kusvika kumagumo ekugamuchira, uye pakupedzisira kupedzisa kubhadharisa.
Kushanda kwekuchaja kweiyo electromagnetic induction isina waya yekuchaja nzira yakakwira se80%.Kuti vagadzirise dambudziko iri, masayendisiti akatanga kuedza kutsva.
Muna 2007, boka rekutsvagisa muUnited States rakabudirira kushandisa tekinoroji yemagetsi ekuvheneka mwenje we60-watt girobhu rinenge 2 metres kubva patsime remagetsi, uye simba rekufambisa magetsi rakasvika makumi mana muzana, iro rakatanga kutsvagisa nekusimudzira boom yemagetsi emagetsi. resonance isina waya yekuchaja tekinoroji.
Nheyo ye electromagnetic resonance isina waya yekuchaja tekinoroji yakafanana neiyo resonance musimboti wekunzwika: mudziyo wekufambisa simba uye mudziyo unogamuchira simba unogadziriswa kune imwechete frequency, uye simba remumwe neumwe rinogona kuchinjana panguva yekunzwa, kuitira kuti coil. mumudziyo mumwe unogona kuva kure.Chinhambwe chinotamisa simba kune coil mune imwe mudziyo, kupedzisa kuchaja.
Iyo electromagnetic resonance isina waya yekuchaja tekinoroji inotyora muganho we electromagnetic induction pfupi-chinhambwe kutapurirana, inotambanudza chinhambwe chekuchaja kusvika pamamita matatu kusvika mana pakureba, uye zvakare inobvisa muganho wekuti mudziyo unogashira unofanirwa kushandisa zvinhu zvesimbi pakuchaja.
Kuti uwedzere kuwedzera chinhambwe chekufambiswa kwemagetsi asina waya, vaongorori vakagadzira tekinoroji yekuchaja tekinoroji.Nheyo yacho ndeiyi: microwave transmitting device uye microwave inogamuchira mudziyo wakazara usina wireless simba rekutapurirana, mudziyo wekutumira unogona kuiswa mupuragi yemadziro, uye mudziyo wekugamuchira unogona kuiswa pane chero yakaderera-voltage chigadzirwa.
Mushure meiyo microwave yekufambisa mudziyo yatumira redhiyo frequency siginecha, chishandiso chinogashira chinogona kubata redhiyo wave simba rakabvongodzwa kubva kumadziro, uye kuwana yakagadzikana yakananga ikozvino mushure mekuonekwa kwemafungu uye yakakwirira-frequency kugadzirisa, iyo inogona kushandiswa nemutoro.
Kuenzaniswa nenzira dzechinyakare dzekuchaja, tekinoroji yekuchaja isina waya inotyora miganhu yenguva nenzvimbo kusvika pamwero wakati, uye inounza kurerukirwa kwakawanda kuhupenyu hwedu.Zvinotendwa kuti nekuenderera mberi kwekuvandudza tekinoroji yekuchaja isina waya uye zvigadzirwa zvine hukama, kuchave neramangwana rakakura.tarisiro yekushandisa.
