目前已有針對汽車駕駛者所設計之資料投影裝置，若 將其應用於機車上時，則係組設於機車帽上之一適當位置 處，但由於機車駕駛者係處於一開放空間，除行駛間所產 生之晃動性較高外，若遇上外界光線較強時，例如太陽光 線，則投影裝置所顯像之行車資訊便容易變為模糊，使得 2者無法清楚掏取。另外，汽車於高速行驶（例如競： 車輛）時，駕敬者也常配戴頭罩或頭蓋以保護駕敬者安 全，此時也需要資料投影裝置以提供行車即時資訊， 時保護駕駛者之安全。而目前之頭蓋式顯示裝置：多J 之中，若使用者有意使用，則需要額外購 貝.，汉口*置内置式投影裝置之頭帽或頭皇，其 較為浪費且成本較高。另外對於有些使用者嘴部附^ 下緣延伸殼體之帽體而言，内置式投影裝置並不容^ 裝，亦即目前之内置式投影裝置使用彈性低 女 改善。 丄而要加以 本紙張尺度賴中關家標^ (請先閲讀背面之注意事項再填寫本頁各攔) 裝 -----訂--------φ^!

If it is applied to a locomotive, it will be set at an appropriate position on the locomotive cap. However, because the locomotive driver is in an open space, In addition to the high sloshing caused by the environment, if the external light is strong, such as the sun's rays, the driving information displayed by the projection device will easily become blurred, making it impossible for the two to clearly extract it. In addition, when the car is driving at a high speed (such as racing: vehicles), the respected people often wear a hood or head cover to protect the safety of the respected people. At this time, a data projection device is also required to provide real-time driving information, and to protect the driver's Safety. The current head-mounted display device: among many J, if the user intends to use it, they need to purchase additional shells. The head or head of the built-in projection device in Hankou * is more wasteful and costly. In addition, for some users whose caps are attached to the lower edge of the casing, the built-in projection device is not to be installed, that is, the current built-in projection device has low flexibility and is improved.丄 The paper standard is based on the Zhongguanjiajiao ^ (Please read the precautions on the back before filling in the blocks on this page) Install ----- Order -------- φ ^! Ximu is for cars or The data projection device designed by the locomotive driver, t is a projection device for direct projection, which occupies a large space, is inconvenient to assemble, and consumes a large amount of electric power. The traditional use of projected real images for eyeball imaging has to increase the distance between the projection lens group and the eyeball if the magnification is to be increased. Therefore, if you want to increase the image magnification, you need to increase the projection system and the workshop. Yu is actually not practical. In addition, the formation of a projected real image = a display device in the eyes, when the user's head moves (such as driving a π locomotive for traffic or the operation of a simulation game), ghost images and Doppler effects will occur; Severe shaking, so the display quality is poor, and the application area is not wide. Please refer to Figures ^ to ". This is a schematic diagram of the effect of the known effect of the Buller effect on the human eye. Just as many video recorders or cameras used by many people at the same time, when users try to focus while holding the camera while moving, they will find The focus of the camera lens has been adjusted back and forth. This is because the camera must try to figure out which part is the main subject you want to shoot = the distance of the subject from the camera, etc., in order to properly focus and shoot a clear image. The human eye is just like the lens of a camera, and the length of the tune #, eye # of the crystal bone can be adjusted quickly and at any time to adapt to different distances. As shown in Figure la, when the image of the object seen by the eye is a static real image 6 The eyeball 5 and the crystalline lens 51 are maintained in a normal state; then refer to FIG. 1b. When the image 6 1 and the eyeball 5 〇1 are in a relative movement, the eyeball 5 〇! In order to grasp the correct image, you must quickly Adjust the length of the eye axis and the curvature of the crystalline lens 5 1 1 as shown in Figure 丨 c. The curvature of the crystalline lens 5 丨 2 becomes smaller and becomes flatter, and the eye axis of the eyeball 502 is as long as Shortened due to the curvature of the crystalline lens 5 12; or as shown in Figure 1d, the curvature of the crystalline lens 5 丨 3 becomes larger and becomes 580589 5. The description of the invention (3) is relatively thick and the axis of the eyeball 503 is adapted to the crystalline lens us Curvature and side length. After taking it, as shown in Figure 丨 e, the crystalline lens 5 丨 4 is adjusted to a correct curvature, and the eye axis is also adjusted to the state of 504. During the adjustment process, because the speed of the object is higher than The speed of the eyeball adjustment will result in the afterimage 62, which is the conventional Doppler effect. In the process of rapid focus adjustment, a large amount of blood flowing through the microvessels around the eyeball will cause pressure on the eyeball for a long time, Too high intraocular pressure caused by frequent adjustment of the focal length will not only cause uncomfortable feeling to the human eye, but also serious fear of retinal detachment! What's more, the light scattering loss in the projection light path is high, so The light use efficiency is low, and the amount of light loss is large. Therefore, a new 7F device is still needed on the market, which can effectively enlarge the image provided by the microdisplay and maintain high resolution, and its imaging method will not The eyeball can be used at close range and for a long time without causing eye discomfort. Because of this, the inventor, in the spirit of active invention, is thinking about a kind of "refractive projection device" that can solve the above problem. After several research experiments, Until the completion of this invention for the benefit of the world. [III. Summary of the invention] Summary of the present invention ^ The main purpose of the present invention is to provide a refractive projection device, which can simplify the mechanism and assembly complexity to be suitable for various hoods.

Description of the Invention (4) — The present invention < Another object is to provide a refractive projection device that can reduce the occupation of 2 rooms and save power consumption Power to reduce the shaking of the image as the user moves. Another object of the present invention is to provide an image display device which can effectively enlarge the image provided by the micro display, occupying a small space, maintaining the image resolution, extending the use time, low material cost, and adjusting magnification. The image contrast ratio is high, and the Doppler and Dragon shadow effects are reduced, which is suitable for a helmet-type display device. In order to achieve the above-mentioned object, the refractive projection device of the present invention is matched with a headgear and a main body, including: at least a display unit; at least one light source for providing light from the display unit; and a refractive lens group for deflection from the The display unit emits or reflects light from the display unit;-a virtual image imaging lens group for reflecting or transmitting the light passing through the refractive lens group and forming the reflected light into a virtual image; and optionally a diffraction The mirror group is located between the refraction mirror group and the virtual image imaging mirror group, and is used to increase the half-brightness angle of the light emitted from the display unit or reflected from the display unit; wherein the refraction mirror group is between the display unit and the Between the virtual image imaging lens group; the angle Y between the refractive lens group and the display unit, the included angle γ is greater than 0 degrees, less than 90 degrees; and the image displayed by the display unit is biased through the refractive lens group Refraction formation-a real image inverted with the original image, and then converted into a virtual image inverted with the original image by the virtual image imaging lens group. The invention is provided with at least one diffractive mirror group in the above-mentioned projection device.

Because the diffractive lens group has an improved half-brightness angle, that is, similar to the micro-focusing feature, the scattered light can be refocused to be close to parallel light, so the imaging information of the projection device can be adjusted by this diffraction and group, so Reduce the loss of light source, relatively improve the visibility and sharpness, so that users can clearly know the relevant image data _ The feature of this month is that it also includes a case to house the above. ,, >, Display unit, light source, diffractive lens group and refractive lens group, and these component groups are arranged outside the above-mentioned hood, so as to achieve the purpose of the present invention.

These 4 figures are schematic diagrams of real image and virtual image differences of eye imaging. Figure 2 shows the real image 4 projected by the conventional projection system. In the case that the eye considers the real image, the eye must be correct __ 9 This paper size applies the Chinese National Standard (CNS) A4 specification ^^ _ χ297 公 楚) -~-580589 A7 B7 V. Description of the Invention (6) Focusing is performed so that the image is imaged on the retina in order to "see" the image 4 丨, and as mentioned in the previous paragraph, the process of focusing will bring pressure to the eye. Figures 3a to 3c show what the eye of the invention sees as a virtual image. In this case, when the imaging lens group (concave mirror) 260 is transparent, the continuous image 4 2 projected by the display unit (not shown) will form a virtual image 4 3 after the imaging lens group 2 6 0, and Because when the human eye observes the virtual image of the reflective surface, the eyeball adjusts its focus on the reflective surface. When the human eye views the virtual image of the reflective surface, the eye does not need to adjust the focal length, but only needs to focus on the reflective surface. And if there is movement of the reflecting object or the image projected on the reflecting surface in the display, the focus of the eye is only on the reflecting surface, that is, the eyeball does not need to adjust the focus greatly because of the reflected object or the image movement in the display, as long as the reflecting object The image of a moving shirt in an image or a monitor is projected on the retina after passing through the lens in the eyeball. The depth of field recognized by the retina can be seen by several layers, that is, the eye can clearly see the image or distinguish the movement of the image, but it does not have to follow the image. Quickly adjust the length of the eyeball to suit the movement of the image, so that the intraocular pressure will not rise. The distance between the virtual image of the non-transparent reflection surface in the eyeball can be roughly explained in Figures 3b and 3c. Because the retina of the eyeball has a multi-layered structure, the eyeball can feel the distance of the image in a multi-layered structure. When the virtual image 44 enters the eyeball through a reflective surface 260, the eyeball will automatically adjust the relative image of the non-penetrating reflective surface through the lens to the retina, and the virtual 44 image formed by reflection on the reflective surface after passing through the eye lens. It will be imaged on the multilayer structure of the retina with the focus adjustment of the ocular lens fixed on the reflecting surface. The eye "feels" through the retina until the image 412 falls before the eye retina, that is, "feels" that the image exists in front of the retina and reflects.

Description of the invention (7) ~ Between the retina, as shown in Figure 3b, and after it is transmitted to the brain, the virtual image is seen in front of the reflective surface, but the focal length of the eyeball has not changed. When the real image is located on the surface of the reflecting surface 26 0, the image 4 丨 3 refracted by the crystalline lens will also fall on the surface of the retina. In combination with Figures 3b and 3c, you can explain the relative motion of the object or image. From the above description, it can be known that when the virtual image moves, the eyeball does not need to adjust the focus, so there is no Doppler effect of increased intraocular pressure, image overlap or afterimage. This problem is also an advantage of virtual image projection imaging. Please refer to FIG. 4, FIG. 5, and FIG. 6. These three figures are schematic diagrams of the refractive lens group used in the present invention compared with the conventional art. FIG. 4 is a conventional direct projection lens using a convex lens 170. Since the light path of the external light source 丨 800 is the same as the direction of the light path of the display unit 1900, the external light source will form the projected image. Strong interference; Figure 5 is a conventional projection system using a concave mirror 1 71 reflection imaging. In this figure, the light path of the external light source 180 is the same as the light path of the image projected by the display unit 190, so it will also There is strong interference; Figure 6 shows the use of refractive imaging in the present invention. In this figure, an angle exists between the convex lens (refractive imaging lens group) 1 72 and the display unit 190.

Under the same power consumption power, the development brightness is improved, and the clear part 33 of the driver 31 can clearly observe and obtain relevant driving information. Please refer to FIG. 9 again, which is the second schematic diagram of the architecture of the present invention. The structure is the same as the above, but the difference lies in that the projection device is arranged above the outer front end of the motorcycle head 2 ′ with a casing i0f. This set-up can also be used for various purposes. It can be known from the foregoing embodiments that the projection display device of the present invention can be used with any existing hood or helmet of any shape, and only needs to be fixed to the hood or burglar with a combination unit, which has a wide range of applications and great flexibility When installing, the new head army or helmet must be purchased additionally.

Description of the invention (13) It is only necessary to adjust the distance, angle and even curvature of the virtual image imaging lens group or the refractive lens group (for example, convex): the adjustment method is simple and the space is small. Compared to the traditional projection display device that forms a real image in the user's eyeball and requires a large space, it has the relative advantages of simplified operation and large space flexibility. Furthermore, since the present invention forms a virtual image in the user's eyes by refraction, which is different from a general projection system that uses projection to form a real image in the user's eyes, there is no need to occupy a large amount of volume as the traditional projection system that forms a real image. Compared with I, the volume occupied by the system is greatly reduced. Of course, the weight is also greatly reduced, which meets the requirements of lightness, thinness, and shortness. In addition, the present invention uses refracted light to form a virtual image that is achieved by the user's eyes. And it is less affected by ambient light, and has better image quality than traditional projection display devices that form a real image on the user's eye. When the user uses it, for the surrounding non-users, due to the refraction imaging of the shadow image, the refraction angle of the light by the transmission virtual image imaging environment group is large, and it will not affect other people around the height of the user's line of sight. The interference is relatively low. More specifically, the refracted image display device of the present invention has the advantages of small cylinder volume, low material cost, low power consumption, easy portability, high flexibility in use, and can reduce production costs, which is quite in line with market demand. In summary, the present invention, regardless of its purpose, means, and effect, sings its characteristics that are quite different from those of the conventional technology, and is a major breakthrough for "refractive projection equipment for traffic vehicles". However, it should be noted that the above-mentioned embodiments are merely examples for the convenience of description, and the scope of rights claimed in the present invention should be based on the scope of the patent application, rather than being limited to the above-mentioned embodiments. ------------- • Equipment --------- Order --------- 9.
