一、手搖手電筒原理是什么

手電筒中(zhong)沒有電(dian)池，在晃動手(shou)電(dian)筒時(shi)，手(shou)電(dian)筒中(zhong)的永磁(ci)體(ti)在線圈(quan)中(zhong)運動，運動是相對(dui)而言的，相對(dui)于永磁(ci)體(ti)而言，線圈(quan)在做切割磁(ci)感(gan)線運動，所以會產生感(gan)應(ying)電(dian)流(liu)，電(dian)流(liu)通過(guo)燈泡，燈泡就(jiu)會發光。

二、手搖手電筒原理圖

手(shou)(shou)(shou)搖手(shou)(shou)(shou)電(dian)筒(tong)是(shi)一(yi)(yi)種(zhong)利(li)用(yong)(yong)大(da)功(gong)(gong)率的(de)三相交流發電(dian)機(ji)進(jin)行(xing)手(shou)(shou)(shou)搖發電(dian)的(de)設備(bei)，利(li)用(yong)(yong)此(ci)(ci)原(yuan)理產生(sheng)的(de)電(dian)能可(ke)以通過開關電(dian)源來對手(shou)(shou)(shou)電(dian)筒(tong)的(de)電(dian)路系統進(jin)行(xing)內置充電(dian)。此(ci)(ci)種(zhong)手(shou)(shou)(shou)電(dian)筒(tong)可(ke)以在較為緊急的(de)情況下使(shi)用(yong)(yong)不僅(jin)具(ju)有較為便于攜(xie)帶的(de)作用(yong)(yong)還具(ju)有結構(gou)簡單的(de)功(gong)(gong)能。在一(yi)(yi)些特殊的(de)情況下可(ke)以進(jin)行(xing)突然性(xing)的(de)照明使(shi)用(yong)(yong)，不僅(jin)如此(ci)(ci)手(shou)(shou)(shou)搖電(dian)筒(tong)的(de)發電(dian)量還可(ke)以在一(yi)(yi)定程(cheng)度上用(yong)(yong)作手(shou)(shou)(shou)電(dian)筒(tong)的(de)備(bei)用(yong)(yong)電(dian)量。

該手搖(yao)動(dong)式自發(fa)電(dian)(dian)手電(dian)(dian)筒(tong)(tong)原理圖(tu)(tu)如圖(tu)(tu)所(suo)示。其結構(gou)示意圖(tu)(tu)如圖(tu)(tu)2所(suo)示。在使(shi)用電(dian)(dian)筒(tong)(tong)時，搖(yao)動(dong)電(dian)(dian)筒(tong)(tong)使(shi)它(ta)的磁鐵7上下移動(dong)，通過(guo)線圈6即(ji)產生電(dian)(dian)能，再(zai)經(jing)圖(tu)(tu)2中的D1-D4整流(liu)，C1貯(zhu)能向電(dian)(dian)池CR2032充電(dian)(dian)通過(guo)開關控制使(shi)發(fa)白(bai)光二極管發(fa)光而實現自發(fa)電(dian)(dian)的功能。

三、 手搖手電筒內部結構是怎么樣的

在(zai)圖中(zhong)，1為(wei)(wei)(wei)圓(yuan)筒(tong)(tong)(tong)形(xing)的塑料(liao)(liao)骨架(jia)。2為(wei)(wei)(wei)發白光二極管3為(wei)(wei)(wei)電(dian)(dian)路(lu)板。4為(wei)(wei)(wei)用銅(tong)片(pian)制作(zuo)的開關。5為(wei)(wei)(wei)予留的CR2032電(dian)(dian)池位置。6為(wei)(wei)(wei)空芯線圈，電(dian)(dian)感量約33mh，線徑約φ.2mm。7為(wei)(wei)(wei)強力磁鐵(tie)，應(ying)使(shi)(shi)它(ta)能在(zai)圓(yuan)筒(tong)(tong)(tong)內(nei)順(shun)利(li)的上下移動。8為(wei)(wei)(wei)聚焦(jiao)鏡(jing)片(pian)，它(ta)與塑料(liao)(liao)骨架(jia)之(zhi)間(jian)裝有橡膠密封(feng)圈，使(shi)(shi)光線更(geng)加集中(zhong)，射(she)程(cheng)更(geng)遠。9為(wei)(wei)(wei)橡膠減震(zhen)圈，避免磁鐵(tie)直接(jie)沖擊塑料(liao)(liao)骨架(jia)。將上面(mian)的材(cai)料(liao)(liao)作(zuo)為(wei)(wei)(wei)一(yi)體，然后放入(ru)右面(mian)的塑料(liao)(liao)電(dian)(dian)筒(tong)(tong)(tong)外(wai)殼10內(nei)。電(dian)(dian)筒(tong)(tong)(tong)的滑動開關11與電(dian)(dian)路(lu)板的銅(tong)片(pian)相(xiang)對應(ying)，再旋上電(dian)(dian)筒(tong)(tong)(tong)蓋12。這個電(dian)(dian)筒(tong)(tong)(tong)就(jiu)能使(shi)(shi)用了。

我們(men)可以(yi)上下搖動這(zhe)個(ge)(ge)電(dian)(dian)(dian)筒(tong)(tong)。它就能(neng)源源不(bu)斷地(di)發光了。由于采用了超亮度(du)的(de)發白光二極管(guan)并且有(you)鏡(jing)片聚焦，亮度(du)和(he)射程大于只使用聚焦電(dian)(dian)(dian)殊的(de)五號電(dian)(dian)(dian)池(chi)(chi)手電(dian)(dian)(dian)筒(tong)(tong)。但這(zhe)個(ge)(ge)電(dian)(dian)(dian)筒(tong)(tong)亦有(you)個(ge)(ge)顯著的(de)缺點(dian)，就是要不(bu)停地(di)搖才能(neng)不(bu)斷地(di)發光。為(wei)了克服(fu)這(zhe)個(ge)(ge)缺點(dian)和(he)節約(yue)成本，我們(men)沒有(you)采用鋰充電(dian)(dian)(dian)池(chi)(chi)增加(jia)儲能(neng)。而是在C1兩端(duan)并接兩只CR2032鋰電(dian)(dian)(dian)池(chi)(chi)。實踐證明，由于這(zhe)個(ge)(ge)電(dian)(dian)(dian)筒(tong)(tong)的(de)耗電(dian)(dian)(dian)量約(yue)為(wei)30mA，新的(de)電(dian)(dian)(dian)池(chi)(chi)可以(yi)用較長的(de)時(shi)間(jian)，電(dian)(dian)(dian)量不(bu)足時(shi)搖動電(dian)(dian)(dian)筒(tong)(tong)又(you)能(neng)用上一(yi)段時(shi)問。反復多次后(hou)電(dian)(dian)(dian)池(chi)(chi)完全失效后(hou)，取(qu)下電(dian)(dian)(dian)池(chi)(chi)仍(reng)然可以(yi)繼續(xu)工作(zuo)。如果你的(de)經濟(ji)條件(jian)許(xu)可，將電(dian)(dian)(dian)池(chi)(chi)換成鋰充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)那是最(zui)理(li)想的(de)了。
