車用后視鏡折疊器
Auto Folding Machine



摘 要：汽車后視鏡俗稱倒車鏡，是汽車主動(dòng)安全裝置，是駕駛員坐在駕駛室座位上直接獲取汽車后方、側(cè)方和下方等外部信息的工具。但是車輛在行車過(guò)程中難免發(fā)生一些意外事故，后視鏡作為安裝在車輛上寬度最寬的零部件，在造成相擦的情況下，最易受到?jīng)_擊，為了最大程度避免擦傷，就需要后視鏡有折疊功能。隨著汽車產(chǎn)品市場(chǎng)觀念的不斷更新和變化，市場(chǎng)對(duì)轎車后視鏡安全性、操作方便性、經(jīng)久耐用性及豪華美觀性等方面提出了更高的要求。特別是汽車電子技術(shù)的發(fā)展，給后視鏡產(chǎn)品的功能升級(jí)帶來(lái)了更大的空間，也促使了這一類操縱簡(jiǎn)單，安裝便捷，價(jià)格低廉的汽車后視鏡自動(dòng)調(diào)節(jié)裝置的問(wèn)世。因此，對(duì)汽車后視鏡的機(jī)構(gòu)原理有所了解是必不可少的。汽車后視鏡屬于重要安全件，它的鏡面、外形和操縱都頗講究。后視鏡的質(zhì)量及安裝都有相應(yīng)的行業(yè)標(biāo)準(zhǔn)，不能隨意。后視鏡折疊器指汽車兩側(cè)的后視鏡在必要時(shí)可以折疊收縮起來(lái)。這種功能在城市路邊停車時(shí)特別有用，后視鏡折疊后能節(jié)省很大的空間。多數(shù)情況下，后視鏡折疊按鈕位于主駕駛位控制玻璃升降按鈕區(qū)域附近，但也有些車型是例外，比如換擋底座區(qū)域。

Abstract: Commonly known as side mirror car rearview mirror is an important vehicle active safety devices, is sitting in the cab driver's seat direct access to external information, tools, steering a car rear-view mirror of the inner core components, to control the door mirror The up and down about adjustments to the driver a proper perspective. With the rapid development of automobile industry momentum, has also led to the development of automotive mirrors industry as a core component of the steering rear view mirrors are continuously optimized and improved, electrically adjustable steering now has been widely by the world States of motor vehicles and parts manufacturers are used. Made at this stage in the major luxury cars steering electric mirrors Eaton purchased in foreign and domestic companies are also using the method of reverse mapping of the imitation, but imitation resulted in poor production results are poor, when the steering operation noise, high currents, these domestic generic products only for some of the domestic market and the small car factory maintenance. The design of the existing share in the foreign company's Electric Power Steering internal planetary gear to carry out optimization to improve design, reduce the steering gear ratio within the gear box, in order to reduce noise, reduce the current, lower power consumption, and maintain electric Steering the original shape and size and structure to enable it to Eaton's products are interchangeable, the localization of the electric steering mirrors.
