市面上現有藍牙耳機充(chong)電接口都是(shi)通過接頭插座插接的(de)，插接的(de)接頭容(rong)易老化磨損，而且(qie)在(zai)電器里(li)后插接的(de)時候，力(li)度(du)不容(rong)易掌握，容(rong)易將接頭損壞。

為了(le)能輕松簡(jian)易地把耳機(ji)從充電(dian)盒里拔(ba)出來(lai)，或不損(sun)傷充電(dian)盒的接頭插(cha)座，延長其的使用(yong)壽命(ming)，兆威(wei)結合藍牙耳機(ji)廠家的結構設計需(xu)求(qiu)，研(yan)發(fa)設計了(le)藍牙耳機(ji)充電(dian)盒升降(jiang)系統(tong)解決方案(an)。

藍牙耳機(ji)充(chong)電(dian)(dian)盒設(she)計(ji)小(xiao)巧美觀，但內部(bu)構(gou)造卻包含(han)了充(chong)放電(dian)(dian)電(dian)(dian)路、保護電(dian)(dian)路、電(dian)(dian)池(chi)三(san)部(bu)分(fen)。需要在(zai)有限的(de)小(xiao)體積空(kong)間里實(shi)現(xian)微型(xing)傳(chuan)(chuan)動(dong)(dong)系(xi)統，這就要求(qiu)行星齒(chi)輪(lun)(lun)(lun)箱的(de)結構(gou)必須小(xiao)且傳(chuan)(chuan)動(dong)(dong)力(li)矩要大。為此，兆威設(she)計(ji)了3.4mm行星齒(chi)輪(lun)(lun)(lun)箱+絲桿副傳(chuan)(chuan)動(dong)(dong)方案(an)，在(zai)藍牙耳機(ji)充(chong)電(dian)(dian)盒內實(shi)現(xian)充(chong)電(dian)(dian)盒的(de)接頭(tou)(tou)插座自(zi)動(dong)(dong)升降，采用3.4MIM微小(xiao)齒(chi)輪(lun)(lun)(lun)、多頭(tou)(tou)絲桿、金屬嵌件注塑、端(duan)面軸承(cheng)等多項設(she)計(ji)，實(shi)現(xian)了耳機(ji)在(zai)微小(xiao)空(kong)間內平穩升降的(de)傳(chuan)(chuan)動(dong)(dong)需求(qiu)。

兆威藍牙(ya)耳機充電(dian)(dian)(dian)盒升(sheng)(sheng)降(jiang)系統解決方案中的升(sheng)(sheng)降(jiang)驅動(dong)(dong)系統常采用(yong)5V低(di)(di)壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)作為供電(dian)(dian)(dian)電(dian)(dian)(dian)源，5V永磁直(zhi)流(liu)(liu)無刷電(dian)(dian)(dian)機作為驅動(dong)(dong)動(dong)(dong)力源。在(zai)供給馬達5V直(zhi)流(liu)(liu)電(dian)(dian)(dian)后，馬達螺旋(xuan)旋(xuan)轉(zhuan)，通過3.4mm行星齒輪箱結(jie)合步(bu)進(jin)電(dian)(dian)(dian)機的馬達蝸(gua)桿與(yu)渦輪進(jin)行一級減速，內管(guan)上(shang)固定(ding)(ding)一個螺母，推桿轉(zhuan)動(dong)(dong)就像擰螺絲(si)，螺母被擰著擰著就上(shang)來了(le)，從而讓艙體(ti)升(sheng)(sheng)起來，通過切換(huan)5V直(zhi)流(liu)(liu)電(dian)(dian)(dian)的正(zheng)負極(ji)，馬達就會反轉(zhuan)，讓模組降(jiang)下去(qu)，從而實現艙體(ti)的智(zhi)能下降(jiang)。此升(sheng)(sheng)降(jiang)齒輪箱傳動(dong)(dong)結(jie)構(gou)比(bi)直(zhi)來直(zhi)去(qu)的升(sheng)(sheng)降(jiang)方式顯(xian)得更加穩(wen)定(ding)(ding)，對電(dian)(dian)(dian)動(dong)(dong)升(sheng)(sheng)降(jiang)結(jie)構(gou)的機械損耗(hao)也會更小，符合低(di)(di)噪(zao)音(yin)、穩(wen)定(ding)(ding)、運轉(zhuan)平穩(wen)的需求。
