Description

本発明は光学投影システムに関し、特に、構造が簡単で、体積が小さく、遠距離の仮想結像が可能で、収差が小さいヘッドアップディスプレイ技術を取り外し可能なハウジング内に結合し、ヘッドアップディスプレイにアフターマーケット製品市場の利便性を具備させた光学投影システムに関する。   The present invention relates to an optical projection system, and in particular, a head-up display technology of simple construction, small in volume, capable of virtual imaging at a long distance, with low aberration, coupled into a removable housing, to head-up display The present invention relates to an optical projection system having the convenience of the aftermarket product market.

ヘッドアップディスプレイ(Head Up Display、HUD)は、使用者が前方の景色を見ると同時に、同じ視野でヘッドアップディスプレイの投射する虚像情報を見ることを可能にし、下を向いてメーターパネルを見る必要がなく、その利便性とそれがもたらす安全性により、自動車のヘッドアップディスプレイは現在大きなトレンドとなりつつある。   The Head Up Display (HUD) enables the user to view forward scenery and at the same time view the projected virtual image information of the head up display, and it is necessary to look down the meter panel The head-up display of automobiles is currently becoming a major trend because of its convenience and the safety it brings.

図1の従来のヘッドアップディスプレイの実施を示す概略図を参照する。ヘッドアップディスプレイは、ケース91を含み、ケース91内にイメージ情報を射出できるイメージング装置92が設置され、少なくとも2つの光学ミラー93、94を経由して、イメージ情報をドライバー前方の自動車ウインドシールドガラス95に投射し、反射を経た後に該イメージ情報の虚像を表示させ、ドライバーに見えるようにする。そのうち、ヘッドアップディスプレイのケース91は二次元のイメージを一定の視野(F.O.V)で投射するため、2つの光学ミラー93、94で二次元のイメージをウインドシールドガラス95に向けて投射するには、一定の体積を備えている必要があり、このケース91を自動車運転席前方の限られた空間に取り付ける際、自動車の前景を犠牲にしたくない場合、自動車の出荷前にメーターパネル内の空間に組み込む必要があり、かつ光路が垂直であるため、ケース91の体積が厚く、組み込みが非常に困難になる。   Reference is made to the schematic drawing illustrating the implementation of the conventional head-up display of FIG. The head-up display includes a case 91, and an imaging device 92 capable of emitting image information is installed in the case 91, and the vehicle windshield glass 95 in front of the driver via the at least two optical mirrors 93 and 94. And, after reflection, display a virtual image of the image information to make it visible to the driver. Among them, since the case 91 of the head-up display projects a two-dimensional image with a constant field of view (FOV), to project a two-dimensional image toward the windshield glass 95 by two optical mirrors 93 and 94, If it is necessary to have a fixed volume and this Case 91 is mounted in a limited space in front of the car driver's seat, if you do not want to sacrifice the foreground of the car, install it in the space in the meter panel before shipping the car. Because of the need and because the optical path is vertical, the volume of the case 91 is thick, making it very difficult to incorporate.

しかしながら、ヘッドアップディスプレイの体積を縮小する、または全体を薄型化するには、虚像の拡大、視野、収差という3つの光学設計上の問題に直面する。小型プロジェクターまたは液晶ディスプレイ(LCD)をディスプレイ装置として使用する場合、遠距離の虚像式ヘッドアップディスプレイを実現するには、バックエンドの虚像リレー光学系(Relay Optics)を組み合わせる必要がある。しかし、虚像リレー光学系の設計は容易でなく、簡潔な光学構造を用いて大きな視野の収差(Aberration)を効果的に除去することはできず、視野範囲が小さいと表示される情報が少なくなり、ヘッドアップディスプレイの応用効果が制限される。このほか、ウインドシールドガラスは不規則な曲面であり、目に反射されるとき、イメージの変形を収差が生じ、イメージの変形と収差を除去することが非常に困難で、表面鏡が大面積の非球面(Aspherical Surface)である、或いはその他のレンズを増設して収差の問題を解決する必要があり、これにより部品の製作コストが増加して生産組み立ての難度も高くなる。これを理由に、現在自動車におけるヘッドアップディスプレイの普及率はずっと上昇していない。   However, in order to reduce the volume of the head-up display, or to make the whole thin, three optical design problems are encountered: enlargement of virtual image, field of view, and aberration. When a small projector or liquid crystal display (LCD) is used as a display device, it is necessary to combine back end virtual image relay optics (Relay Optics) in order to realize a long distance virtual image head-up display. However, designing a virtual image relay optical system is not easy, and a simple optical structure can not be used to effectively eliminate large field aberrations, and less information is displayed when the field range is small. The application effect of the head-up display is limited. Besides, the windshield glass is irregularly curved, and when it is reflected to the eye, the distortion of the image is aberrated, it is very difficult to remove the distortion and aberration of the image, and the surface mirror has a large area. It is necessary to solve the problem of aberration by adding an aspheric surface (Aspherical Surface) or other lenses, which increases the manufacturing cost of parts and increases the difficulty of production assembly. Because of this, the penetration rate of head-up displays in automobiles is not increasing at present.

このため、上述の従来品の問題と欠点をどのように解決し、虚像の拡大を達成するとともに、ウインドシールドガラスによるイメージの変形と収差をなくし、全体的なイメージの品質を向上するかが、本発明の発明人とこの産業に従事する関連企業が改善を研究する方向性となっている。   Therefore, how to solve the problems and drawbacks of the conventional products described above and achieve enlargement of a virtual image and eliminate image distortion and aberration by the windshield glass to improve the overall image quality, The inventor of the present invention and a related company engaged in this industry have a direction to study improvement.

本発明の発明人は上述の欠点に鑑み、関連試料を収集し、多方面での評価と検討を経て、かつこの業界に従事して蓄積した長年の経験に基づき、度重なる試作と変更を重ね、本発明の構造が簡単で体積が小さく、遠距離の仮想結像が可能で、収差が小さいヘッドアップディスプレイ技術を取り外し可能なハウジング内に結合し、ヘッドアップディスプレイにアフターマーケット製品市場の利便性を具備させた、光学投影システムの特許を設計したものである。   In view of the above-mentioned drawbacks, the inventor of the present invention has repeatedly collected trial samples and changes based on many years of experience after collecting relevant samples, evaluating and studying in various fields, and engaging in the industry.

FIGS. 2 and 3 show a mirror positional relationship diagram and a schematic view of an imaging path, respectively, according to a preferred embodiment of the present invention. As can be clearly seen from these figures, the optical projection system according to the invention comprises an imaging unit 1, a reflector 2, a reflective curved mirror 3 and at least one optical lens 4,
The imaging unit 1 projects at least one scheduled image 12;
The reflecting mirror 2 is disposed at one side of the imaging unit 1 to receive and reflect the expected image 12;
The reflecting curved mirror 3 is disposed on one side of the imaging unit 1 and located on the reflecting path of the reflecting mirror 2 and used for adjusting the imaging path and reducing the aberration of the virtual image, and the scheduled image 12 Is projected onto the windshield glass 7 and further reflected to the eyes of the user, and a virtual image of the predetermined image 12 is imaged outside the windshield glass 7, and the reflecting curved mirror 3 includes a plurality of curvatures. , And the curvature is defined by a mathematical equation,
The at least one optical lens 4 is placed on the imaging path to magnify the predetermined image 12 and the optical lens 4 is a Fresnel lens and a protective layer 41 on the optical lens 4 Is provided.

そのうち、該結像ユニット1と該反射鏡2間に第1挟角αが定義され、該反射鏡2と該反射曲面鏡3間に第2挟角βが定義され、該結像ユニット1と該反射曲面鏡3間に第3挟角γが定義され、かつ該第1挟角αが15度から70度であり、該第2挟角βが30度から90度であり、該第3挟角γが75度から140度であり、かつ該第1挟角αの最適値が30度から40度であり、該第2挟角βの最適値が50度から60度であり、該第3挟角γの最適値が95度から105度である。   Among them, a first included angle α is defined between the imaging unit 1 and the reflecting mirror 2, and a second included angle β is defined between the reflecting mirror 2 and the reflecting curved mirror 3. A third included angle γ is defined between the reflecting curved mirror 3 and the first included angle α is 15 to 70 degrees, and the second included angle β is 30 to 90 degrees, the third The included angle γ is 75 to 140 degrees, and the optimum value of the first included angle α is 30 to 40 degrees, and the optimum value of the second included angle β is 50 to 60 degrees, The optimum value of the third included angle γ is 95 degrees to 105 degrees.

上述の部材を組み立てると、図からはっきりと分かるように、本発明の光学投影システムは主に、結像ユニット1と、反射鏡2(平面鏡または凸面鏡)、反射曲面鏡3と、光学レンズ4(好ましくはフレネルレンズであるが、凸レンズまたは光学的透明薄型材としてもよい)等とウインドシールドガラス7を組み合わせ、遠距離の虚像を形成する。そのうち、該結像ユニット1と、該反射鏡2と、該反射曲面鏡3は同一水平面に位置するため、結像ユニット1は好ましくは予定イメージ12を平行光で側面方向に該反射鏡2上に投射し、自由な曲率的の反射曲面鏡3を利用して反射光線の経路を変えて上方向に射出させ(このとき結像経路が該反射曲面鏡3から上に向かう垂直成分を獲得する)、同時に収差を補正する目的を達成するとともに、光学レンズ4が防護層41を備えており、防塵保護機能を有するため、別途設置される透光部材(プラスチック、ガラス、アクリル等)の結像効果への影響を回避することができる。そのうち、反射曲面鏡3は複数の曲率を含有するため、反射鏡2の発散距離及び角度に合わせて全面的に収差を補正できる。このため該反射曲面鏡3の曲率は固定された曲率ではなく、精密な計算を経て1つの数学方程式を導き出し、該数学方程式に基づきこれらの特殊な曲率設計を有する反射曲面鏡3が製作される。該数学方程式は下式(1)に示すとおりである:   The optical projection system of the present invention mainly comprises the imaging unit 1, the reflecting mirror 2 (plane mirror or convex mirror), the reflecting curved mirror 3, and the optical lens 4 Although it is preferably a Fresnel lens, it may be a convex lens or an optically transparent thin material or the like) and the windshield glass 7 in combination to form a virtual image of a long distance. Among them, since the imaging unit 1, the reflecting mirror 2 and the reflecting curved mirror 3 are located on the same horizontal plane, the imaging unit 1 preferably sideways the projected image 12 with parallel light on the reflecting mirror 2 , And use the free curved reflective curved mirror 3 to change the path of the reflected light and emit it upward (in this case, the imaging path acquires a vertical component directed upward from the reflective curved mirror 3). ) At the same time to achieve the purpose of correcting the aberration, and since the optical lens 4 is provided with the protective layer 41 and has a dustproof protection function, imaging of a separately installed translucent member (plastic, glass, acrylic, etc.) The influence on the effect can be avoided. Among them, since the reflecting curved mirror 3 contains a plurality of curvatures, it is possible to correct the aberration entirely in accordance with the diverging distance and angle of the reflecting mirror 2. Therefore, the curvature of the reflecting curved mirror 3 is not a fixed curvature, but one mathematical equation is derived through precise calculation, and the reflecting curved mirror 3 having these special curvature designs is manufactured based on the mathematical equation. . The mathematical equation is as shown in the following equation (1):

Figure 2019045843
Figure 2019045843

予定イメージ12は、反射曲面鏡3で初歩的に拡大されるほか、反射曲面鏡3の方向転換後の結像経路を経由し、さらに光学レンズ4の拡大効果を経て、該予定イメージ12がウインドシールドガラス7に投射され、ウインドシールドガラス7により該予定イメージ12を使用者の目に反射させ、該ウインドシールドガラス7の外で屈折して該予定イメージ12の虚像が形成される(使用者前方約2メートルの位置)。このように、上述の構造によって、第1挟角α、第2挟角β、第3挟角γの配置を組み合わせ、三角結像技術で遠距離の仮想結像を達成し、かつ該光学レンズ4がフレネルレンズであるため、レンズの必要体積を効果的に縮小し、同時に収差の問題を克服することができる。   The scheduled image 12 is expanded primarily by the reflecting curved mirror 3 and passes through the imaging path after the turning of the reflecting curved mirror 3 and the expanding effect of the optical lens 4 to make the projected image 12 a window. The projected image 12 is projected onto the shield glass 7, reflected by the windshield glass 7 to the eyes of the user, and refracted outside the windshield glass 7 to form a virtual image of the projected image 12 (front of the user) About 2 meters). As described above, according to the above-described structure, the arrangement of the first included angle α, the second included angle β, and the third included angle γ is combined to achieve virtual imaging at a long distance by triangular imaging technology, and the optical lens Since 4 is a Fresnel lens, the required volume of the lens can be effectively reduced and at the same time the problem of aberration can be overcome.
