Description of the invention (1) [I. Technical Field to which the Invention belongs] The present invention relates to a refractive projection device, and particularly to a refractive projection device suitable for a traffic carrier. [II. Prior technology] The head up dispiay project important driving information near the eyes and head up, so that the driver of a traffic vehicle (such as steam soil) is in the process of driving respect. No need to look down at the dashboard to ignore the traffic situation ahead, reducing the possibility of accidents. It has been widely used in automobiles and airplanes. The conventional head-up display device is placed in a space above a car dashboard, and is projected on a windshield of a traffic vehicle to form a real image. Ren Ru ^ shot a private real image, t was directly interfered by external light. In particular, the sunlight shot by the sun gate often causes insufficient contrast of the image projected by the head-up display device, and a white fog-like image is generated, making it difficult for the user to identify the information displayed by the head-up display device. In addition, the traditional projection device forms a display shock that projects a real image in the eyes. When the user's head moves (for example, when the car is moving), it will produce ghosting and blurring or severe shaking caused by the Doppler Effect. So the display quality is not good. [III.

In order to allow your review committee to better understand the invention Technical content, the second preferred embodiment is described below. Please refer to FIG. 1, which is a schematic diagram of a first embodiment of the present invention. The refractive projection device of the present invention shown in the figure is located in front of a driver's seat of a car and includes a display single SU'-convex lens 2 (that is, the refractive lens group of this embodiment): a calender film 3 next to the convex lens 2, And—Wind-breaking glass 4 (that is, in the present embodiment (virtual image imaging lens group), the convex lens has an included angle Y, wherein the angle Y is about 30 degrees.

Description of the invention (5)-Please refer to FIG. 2, which is a partial cross-sectional view of this embodiment. In this embodiment, a single M i projects a letter A in a horizontal direction and passes through a pan-convex lens 2 (that is, this embodiment). Example of the refraction lens group) After being refracted to form an erect real image, ^, it is reflected by the child's windshield 4 (that is, the virtual image imaging lens group of this embodiment) and is reflected in the eyes of the user. Shape & an enlarged upright virtual image a. Θ 显 不 70 70 is arranged between the focal length of the convex lens 2 (ie the refractive lens group of this embodiment) and the double focal length to form an enlarged inverted real image Convex through 1¾ 2 (ie, the refractive lens group of this embodiment). Then the enlarged inverted real image is located within the focal length of the concave mirror, and is converted to form an enlarged virtual image to the user's eyeball. The filter The function of the film 3 is that, as is well known, sunlight contains various wavelengths of light, so the scattering produced by the sunlight will cause scattering at many angles with different wavelengths of light; and the function of the filter film 3 is to filter out Light outside a specific wavelength can greatly reduce the scattering phenomenon caused by incident light and further increase the m-definition of the image projected by the present invention. There is no limitation on the wavelength of the light passed through the filter, and a monochromatic filter is preferred. In this embodiment, the color of the image projected by the display unit is green, so a filter film capable of filtering light outside the green light band is selected. In this state, 'external incident light 51 will be filtered by the filter first, and only the green light is left.' Then most of the incident light will be refracted by the refraction lens group at a large angle to the inside of the housing 6 and be Absorption (the shell 6 is black), so most of the external light sources do not affect the image projected by the display unit.

Description of the invention (6 ^ " ~-of Green, so the projected image can greatly improve the white haze-like image phenomenon produced by the conventional projection system. Finally, see FIG. 3, which is a partial scraped view of the second embodiment of the present invention. In this embodiment, Most of the same as the first embodiment, only a matting sheet 31 is provided on the filter film 3 (the matting sheet 31 has a function that when the incident light 52 of the external light source comes to the convex lens, the The matting sheet 3 can scatter most of the incident light 52 to prevent it from affecting the image projected by the display unit 11 and thereby increasing the sharpness of the image. In particular, the general daylight is divided between the line of sight of the image receiver (such as the driver). The angle is incident on the wind-receiving glass 4 (that is, the virtual image imaging lens group of this embodiment). The incident light is incident on the convex lens 2 (that is, the refractive lens group of this embodiment), but when Putian daylight is incident on the surface of this convex lens 2, it is largely scattered by the extinction sheet. Therefore, most of the incident sunlight is incident on the convex lens 2. The surface is eliminated. Even if a small part of the sunlight is incident through the convex lens (ie, the refractive lens group of this embodiment), the angle of incidence is caused by the refractive effect of the convex lens 2 (ie, the refractive lens group of this embodiment). It is not equal to the exit angle, so Da Shao's incident transmission light will be deflected outside the display unit, instead of directly hitting the VFD display of the display unit 11. Therefore, the image displayed by the display unit η can avoid ambient light. Influence, improve the contrast and sharpness of the image 0 ... The refractive projection device of the present invention uses a filter film to increase the brightness and contrast of the formed image, improve the definition, and reduce or eliminate the interference of external ambient light. The imaging principle of the present invention is Virtual image imaging is mainly formed by a refraction lens group (convex lens)-the national standard A, the description of the invention, which is placed upside down on the original image and left and right. 7) Two? A virtual image imaging unit (concave mirror, concave through: Lu Xiangxiong: Cheng Yi upside down with the original image, the left and right magnification of the head = the second line uses the virtual image to form the eyeball, so The blurring is reduced. In addition, the image mode caused by the Doppler effect and ghost effect: = In the present invention, refracted light is used to form a virtual image. • When magnifying an image, only the virtual image imaging lens group lens needs to be adjusted. ^ Birefringence The distance, angle, and even curvature of the lens group (such as a convex lens), shape: =, simple adjustment method 'occupies little space. Compared to the traditional "Xianwan" official eyeballs, and requires a large space projection display device ^' It has the relative advantages of simplified operation and flexible use of space. Furthermore, since the present invention uses refracted light to form a virtual image on the user's eyeball, the contrast of the imaging is high, the mortuary effect is large, and it is less affected by the ambient light. Compared with the traditional projection of the real image on the user's eyeball, Display device with better image quality. When the user is using it, the surrounding non-users, because the image is refraction imaging, the light refraction angle of the transmission virtual image imaging environment group is large, and it will not affect other people around the same height as the user's line of sight. low. It should be noted that the above are merely examples, and are not limited to the examples. For example, those who do not depart from the basic structure of the present invention should be the scope of rights claimed by the patent, and the scope of the patent application shall prevail. [V.
