Description
Technical field
The utility model relates to looks squarely display technique field, particularly relates to a kind of device eliminating automobile head-up display projection image ghost image.
Background technology
Automobile head-up display be a kind of driver of allowing when driving sight line do not need to leave the various information that road surface just can read automobile, as the speed of a motor vehicle, rotating speed, water temperature, the device of the information such as oil mass.
In the automobile head-up display that current Ge great mainstream automotive manufacturer configures, in order to eliminate ghost image, strengthen reflecting effect, the method for employing is the resin glue structure before changing in shelves glass sandwich, in common front shelves glass sandwich, resin glue is parallel construction, and thickness is unification evenly; And in automobile head-up display device, needing to change light path makes the virtual image of optical projection system overlap, just need the structure changing resin glue, become a kind of up big and down small wedge structure, utilize the refraction different principle of light in different medium, make glass front together with the virtual image coincidence of reverse side, eliminate ghost image, also strengthen reflecting brightness.
But thereby produce high cost, manufacture difficulty is large, the problem that yield rate is low, head-up display will be installed additional in producer, configure the front shelves glass of a whole Zhang Anggui, even the cost of shelves glass has exceeded the price of head-up display before one, causes and just can only be furnished with in the height configuration vehicle of high-end automobile.
Utility model content
In view of eliminating head-up display projection image ghost image above shortcomings at present, the utility model provides a kind of device eliminating automobile head-up display projection image ghost image, can reach the identical display effect of high-end vehicle in low configuration vehicle, reflection ray is overlapped, brightness strengthens.
For achieving the above object, the following technical scheme of employing of the present utility model:
A kind of device eliminating automobile head-up display projection image ghost image, comprise the head-up display to described windshield projects images, the device of described elimination automobile head-up display projection image ghost image also comprises the wedge shape reflectance coating being arranged on windshield inside surface, described wedge shape reflectance coating is that one end is thick, the wedge shape reflectance coating other end is thin, described wedge shape reflectance coating is arranged on head-up display in the region that windshield projects, its thicker end is towards the coboundary of windshield, and thinner end is towards the lower limb of windshield.
As the preferred technical solution of the present invention, the angle of wedge angle of described wedge shape reflectance coating is 0.89 degree.
As the preferred technical solution of the present invention, the thicker end height of described wedge shape reflectance coating is 2.39mm, and thinner end height is 0.69mm.
As the preferred technical solution of the present invention, described wedge shape reflectance coating is rectangle, and its length is 110mm, and width is 75mm.
The advantage that utility model is implemented: realize second virtual image that head-up display projection light formed through windshield internal surface reflection and overlap with first virtual image that head-up display projection light reflects to form through windshield outside surface.And the cost making wedge shape reflectance coating is low, can reach the identical display effect of high-end vehicle in low configuration vehicle, in addition, wedge shape reflectance coating also can make the brightness of projection ray be enhanced, and makes to drive the image that personnel are seen more limpid in sight.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
