490408 經濟部智慧財產局員工消費合作社印製 A7 B7 五、發明說明（/ ) 【發明領域】 本發明是有關於一種車用側視鏡，特別是有關於一種 用供車輛駕駛人可以精確且容易地觀察車輛後方景象的側 視鏡，而不會相對於車輛之行進方向產生失真的情形，並 且可以減小一個朝向該車輛內部突伸之殼體的突出長度。 【發明背景】 一般而言，一部車輛在其每一個前側窗框之駕駛側和 乘客座側均有一對側視鏡，以使得駕駛人可以觀看相對於 其車輛行進方向之後方的情形。 用於車輛之傳統的側視鏡是屬於平面反射鏡的型式， 其所具有之一個幾乎爲平面反射的表面係相對於該車身之 一條前後延伸的軸線而水平地突伸超出該前側車體，而這 種情形係造成空氣的阻力。此種空氣阻力係增加汽車的耗 油量，也因而造成空氣的污染。 此外，這種平面反射鏡型式的側視鏡係具有一個相當 小的後方投射角，這種情形可能造成該後視鏡在諸如下雨 或下雪等不良天候的狀況下，暴露於水滴、溼氣和霜雪， 因而造成駕駛人不易於觀察其後方的交通狀況。結果，很 可能具有導致意外事故的危險。 在考量這些問題之後，在PCT申請案第W096/31365 號以及美國專利申請案第5,559,640號中，係分別揭露一種 可以減少該延伸至車身以外之突出長度的側視鏡，而且該 側視鏡係使用一種光學元件以可增加後視角度。 在該PCT申請案第W096/31365號中，因爲該車輛係 5 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） --------------------訂---------^ IAWI (請先閱讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作社印製 490408 A7 B7 五、發明說明（2) 設置有四個向上和向下的透鏡，以及該等透鏡之間係設置 有兩個反射鏡，因此由於該車輛的震動而很難調整一個光 學軸線。此外，駕駛人最終藉以觀察後方之交通狀態的一 個接目透鏡（屏幕透鏡）係安裝在一個所謂的 ''柱狀物〃 的下側部分。結果係造成一個問題，即該側視鏡的構造和 安裝將變得非常複雜。 此外，該根據上述PCT申請案中之側視鏡的構造，其 將不易於同時使長距離以及短距離的物件聚焦，尤其更不 易將該側視鏡設計成可以單一倍率而觀看後方的景象。 另外，在該根據美國專利申請案第5,559,640號的側視 鏡中，該車身之外側係設置有一個相當小的凸透鏡，以及 在該凸透鏡與駕駛人之間係安裝有一個放大鏡，因而使得 該駕駛人可以看見車輛後方的交通情形。然而，該映入駕 駛人眼睛之放大的影像將會在垂直和水平的方向上產生嚴 重的失真情形。結果係產生一個問題，即該車用側視鏡並 不能實質地發揮其功能。 因此，在本發明案之申請人的韓國新型公開案第 76588號以及美國專利公開號第5,264,962號中，即揭露一 種針對於解決該等傳統問題的 ''車用側視鏡〃。 由於，本案申請人先前所提出之車用側視鏡係包含有 兩個透鏡組，亦即一個接物透鏡組和一個接目透鏡組，以 及包含有一個嵌置在該二透鏡組之間的平面反射鏡，因此 ’其能夠提供一個通達該車輛後方之相當寬廣的視野，以 及一個相當短的光學軸線，因而能夠讓駕駛人容易地觀看 6

一倍率的影像並不容易。尤其，另一個問題是，欲使駕駛 人的眼睛與安裝在靠近駕駛人側邊之殼體內的接目透鏡組 之光學軸線達成一致是很不容易的。 【發明槪要】 因此’本發明的一個目的，是要提供一種可供車輛駕 駿人用以精確且容易地觀察車輛後方景象的側視鏡，而不 會在相對於車輛行進之方向上產生失真的情形，並且可以 減少一個向內突伸於車輛內部之殻體的突出長度。 爲達成本發明上述之目的，其所提供的一種車用側視

圖2係爲圖1中所示之車用側視鏡的一個內腔部分的 延伸視圖。圖3係爲一個說明圖1中之光學元件設置方式 的立體圖。圖4係爲說明一條光學路徑的視圖，其中該光 學路徑係對應於該沿著圖1中之接物透鏡組的垂直方向之 中心線。圖5係爲一個說明該車用側視鏡的使用狀態參考 圖。 如這些圖式中所示，該接物透鏡系統係具有一個光學 傳輸元件9，該光學傳輸元件9係設置在該外側管狀單元5 內部並且用以將一個在該車輛1後側之影像折射和反射以 被聚集在車輛1內部。 一個光學傳輸元件9係構造成一個所謂阿米其式稜鏡 ，該光學傳輸元件9係整合著一凸透鏡型式之接物透鏡、 一上側反射單元13和一下側反射單元15，其中該凸透鏡 型式的接物透鏡係用以折射一束欲被聚集之通過的光線； 該平面反射鏡型式的上側反射單元13係以一特定角度（在 本實施例中爲45°)設置在該接物透鏡11的焦距之內，並 且用以反射該通過接物透鏡11之水平中心線上側的光線； 而該下側反射單元15則是設置在該上側反射單元13的一 下側而且位在該接物透鏡11的焦距以內，以使得該上側反 射單元13係與該接物透鏡11之一條水平中心線對應的交 16 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） ---------------------訂---------線 (請先閱讀背面之注意事項再填寫本頁)

一倍率或特定倍率的影像；而該第三反射單元Π’則是設置 在光學傳輸元件9與接目透鏡19之間，以用於反射該光學 傳輸元件9所接收的影像。 在本發明中，該第三反射單元Π係可以構造成一個設 置在該接物透鏡11之焦距以外的平面反射鏡，以使得該被 上側反射單元13和下側反射單元15所反射的光學路徑（ LPL和LPR)可以相互交錯，並且可以構造成一個稜鏡。 此外，該接目透鏡19係構造成一個單一凸透鏡。然而，根 據在該側視鏡與該駕駛人之間的距離，亦即在該側視鏡距 離駕駛人非常遙遠的情況下，例如：該在客座側邊上的側 視鏡，便可以在該內側管狀單元7的最外側部分安裝一個 平凸透鏡，以及在該平凸透鏡與該第三反射單元17之間安 裝一個凹凸透鏡。 藉由這種結構，當在該連接著殼體3之車輛1後側的 物件影像以一個幾乎呈平行光線的形式而通過該接物透鏡 11時，該上側反射單元13會以一個對應於入射角之反射 的角度，而將該經由接物透鏡11之水平中心線上側部分的 投射光線反射在該下側反射單元15上，而該下側反射單元 17 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） ' " --------------------訂---------線"^1^" (請先閱讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作社印製 490408 A7 B7 五、發明說明（π ) 15也會將相同的投射光線向上反射到該第三反射單元17。 同時，該下側反射單元15會以一個特定的反射角度， 而將該經由接物透鏡11之水平中心線下側部分的投射光線 反射在該上側反射單元13上，並且該上側反射單元13也 會以一個對應於入射角度的反射角而將相同的投射光線向 下反射到該第三反射單元17。 因此，該分別由上側反射單元13和下側反射單元15 所反射的光線，會相互地交錯在該接物透鏡的焦點上，並 因而會在該第三反射單元17上形成一個側向和縱向均已校 正的影像。 該被第三反射單元17所反射的光線，會通過該由接目 透鏡19和光學傳輸元件9所共同構成之無焦點的光學系統 ，且會被放大以形成一個具有單一倍率或是一個特定倍率 的影像，以及會以一幾乎呈平行光線的形式傳輸到駕駛人 ;因而，該駕駛人能夠精確而容易地觀察到後方的事物， 而不會有失真的情形。 同時，在該接物透鏡11或是接目透鏡19之表面形成 水滴或霜雪的情況下，當該空氣入口 25的開關裝置（未圖 示）達成開啓的狀態時，空氣便可進入該空氣導引管27。 而進入空氣導引管27的空氣係藉由過濾元件33而進行過 濾，並且分別經由該第一歧管29和第二歧管31而噴注到 該接物透鏡11和接目透鏡19的表面上，因而可以將形成 在該接物透鏡11和接目透鏡19之表面上的水滴或霜雪排 除。 18 --------------------訂---------線

Description of the Invention (/) [Field of the Invention] The present invention relates to a side view mirror for vehicles, and in particular to a method for vehicle drivers to be accurate and easy A side view mirror for observing the scene behind the vehicle without any distortion relative to the direction of travel of the vehicle, and can reduce a protruding length of a case protruding toward the interior of the vehicle. [Background of the Invention] Generally, a vehicle has a pair of side mirrors on the driving side and the passenger seat side of each of its front side window frames, so that the driver can view the situation behind the vehicle relative to the direction of travel of the vehicle. The traditional side-view mirror used for vehicles is a type of flat mirror, which has a nearly flat-reflecting surface that projects horizontally beyond the front side of the body relative to an axis extending back and forth from the body. This situation causes air resistance. This kind of air resistance increases the fuel consumption of the car, which also causes air pollution. In addition, this type of flat mirror type side view mirror system has a relatively small rear projection angle. This situation may cause the rear view mirror to be exposed to water droplets, wetness under adverse weather conditions such as rain or snow. Gas and frost and snow make it difficult for drivers to observe the traffic conditions behind them. As a result, there is a high risk of accidents. After considering these issues, PCT Application No. W096 / 31365 and U.S. Patent Application No. 5,559,640 respectively disclose a side view mirror that can reduce the protruding length extending beyond the vehicle body, and the side view mirror system Use an optical element to increase the backsight angle. In the PCT application No. W096 / 31365, because the vehicle is a 5-paper standard, it applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -------------- ------ Order --------- ^ IAWI (Please read the notes on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 490408 A7 B7 V. Description of the invention (2 ) Four upward and downward lenses are provided, and two mirrors are arranged between these lenses, so it is difficult to adjust an optical axis due to the vibration of the vehicle. In addition, an eyepiece lens (screen lens) through which the driver finally observes the traffic conditions behind is mounted on the lower part of a so-called '' column 〃 ''. The result is a problem that the construction and installation of the side view mirror becomes very complicated. In addition, according to the structure of the side view mirror in the above PCT application, it is not easy to focus both long distance and short distance objects, and it is even more difficult to design the side view mirror to view the rear scene at a single magnification. In addition, in the side view mirror according to U.S. Patent Application No. 5,559,640, a relatively small convex lens is provided on the outer side of the vehicle body, and a magnifying glass is installed between the convex lens and the driver, so that the driver One can see the traffic situation behind the vehicle. However, the magnified image reflected in the eyes of the driver will cause severe distortion in the vertical and horizontal directions. As a result, there is a problem that the side view mirror for the vehicle cannot substantially perform its function. Therefore, in the Korean New Publication No. 76588 and the U.S. Patent Publication No. 5,264,962, which are the applicants of the present invention, a `` vehicle side view mirror '' for solving these traditional problems is disclosed. Because the vehicle side view mirror system previously proposed by the applicant of this case includes two lens groups, that is, an objective lens group and an eyepiece lens group, and an optical lens embedded between the two lens groups. A flat mirror, so 'it can provide a fairly wide field of view to the rear of the vehicle, and a relatively short optical axis, so that it can be easily viewed by the driver. 6 This paper size applies to the Chinese National Standard (CNS) A4 specification ( 210 X 297 mm) ------------ 0 ------- 丨 Order --------- line (Please read the precautions on the back before filling this page ) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 490408 A7 _ B7 V.
