Description
Technical field
The utility model relates to the optical imaging system that one is exclusively used in vehicle-mounted HUD (HUD), particularly relates to a kind of virtual image forming system of triple reflection.
Background technology
HUD (HeadUpDisplay) is the abbreviation of HUD or head-up display, it is the flight supplementary instrument generally used on aircraft, its major function is that assisting in flying person is in the process of executing the task, do not need to bow the important information just seeing that he needs, and then reduce pilot and bow and check the frequency of instrument, avoid notice to interrupt and lose the control to state consciousness, improving pilot thus and performing the safety guarantee in aerial mission process.In recent years, because the development of auto industry grows, HUD also gradually popularization and application to this field, and spread out and stretch out vehicle-mounted HUD, the HUD that its major function and aircraft use is similar, is driver and provides the information such as road conditions, communication, note, navigation, meteorology in real time, and by the information displaying of necessity on HUD, do not take sb's mind off sth while helping driver to understand various information when driving, improve operation safety.
Those skilled in the art knows, various information shows mainly through the principle of optical imaging system by vehicle-mounted HUD, so that driver checks information when not bowing, and in prior art, imaging system on vehicle-mounted HUD is secondary reflecting imaging, the real image image planes of the first time imaging of being launched by ray machine are due to towards front windshield glass window, and it is unobstructed, namely be exposed under periods of direct sunlight, cause the reflective degree of real image image planes itself more serious, image is caused to turn white, contrast is lower, and then make the virtual image that reflects through these real image image planes very unintelligible, the information that driver watches virtual image display is more painstaking.In addition, existing imaging system virtual image image planes are comparatively near, are substantially no more than 1m, limit the amplification effect of virtual image image planes.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, there is provided that a kind of modern design, structure are simple, the virtual image forming system of the triple reflection of imaging clearly, this imaging system is exclusively used in vehicle-mounted HUD, and its imaging effect is not by the impact of extraneous light intensity.
For achieving the above object, the utility model adopts a kind of virtual image forming system of triple reflection, comprise pedestal, ray machine, optical screen, mirror reflection surface and polynomial expression reflecting curved surface, described pedestal offers skewed slot, the two ends of this skewed slot form low order end and high order end respectively, described ray machine is installed in the low order end position of described skewed slot, described optical screen is installed in the high order end position of described skewed slot, described ray machine is formed corresponding along the gradient direction of described skewed slot with described optical screen, described mirror reflection surface is installed on described pedestal, and it is corresponding with the reflection direction of described optical screen, described polynomial expression reflecting curved surface is installed on described pedestal, and it is corresponding with the reflection direction of described mirror reflection surface.
As further improvement of the utility model, the high order end position of described skewed slot is provided with light shield, the opening direction of this light shield is corresponding with described mirror reflection surface, and described optical screen is in described light shield.
As further concrete improvement of the present utility model, described skewed slot to intert in described pedestal and forms damascene structures, and the low order end of this skewed slot is closed state, and near the bottom face of described pedestal; The high order end of this skewed slot is open state, and near the upper surface of described pedestal; The position that described mirror reflection surface is connected with described pedestal offers radiating groove, and this radiating groove is communicated with the low order end of described skewed slot.
The utility model is by the above-mentioned improvement to prior art, reach following five aspect beneficial effects: 1, because the imaging system in the utility model is imaging by triple reflection, namely first on optical screen, real image is projected by ray machine, then by optical screen, real image first reflection is amplified in mirror reflection surface, by mirror reflection surface, virtual image second time is reflected and is amplified on polynomial expression reflecting curved surface again, finally by polynomial expression reflecting curved surface, virtual image third time is reflexed to driver eye position, realize driver not need to bow and just can be correlated with the effect of the messages such as road conditions by real time inspection, in this process, relative to the secondary reflecting imaging of HUD vehicle-mounted in prior art, the image-forming range of the utility model triple reflection is obviously much larger than the image-forming range of secondary reflection, therefore more the areas imaging of the virtual image on polynomial expression reflecting curved surface can effectively be amplified, for driver, see also more clear, 2, because ray machine in the utility model is installed in the bottom end (i.e. low order end) of skewed slot, optical screen is then installed in the upper end (i.e. high order end) of skewed slot, ray machine projects real image on optical screen along the gradient direction of skewed slot, in the process of projection, because ray machine is in low order end position, external light source is difficult to the projection sharpness having influence on ray machine, and the outlet openings projecting optical screen is all (be namely subject to blocking of skewed slot sidewall and roof) in skewed slot, simultaneously known by the utility model structure of foregoing description, optical screen is the front windshield glass window of automobile dorsad, and in the daytime in driving conditions, major part light is all shine in from front windshield glass window, therefore, after the installation site of optical screen has carried out arranging as this by vehicle-mounted HUD of the present utility model, effectively reduce the impact of video picture on daylight aiming screen further, ensure that the video picture quality that vehicle-mounted HUD is final, 3, after skewed slot is arranged to damascene structures by the utility model, ray machine is made to be in base interior space, and make ray machine in pedestal, form concealed structure, isostructural imaging system above pedestal is arranged on relative to the split setting of ray machine in prior art and pedestal or ray machine, this damascene structures of the present utility model achieves the effect that pole reduces the volume (i.e. size) of this imaging system as much as possible on the whole, especially in the height of this imaging system, the height and the ray machine that at least reduce ray machine project the height of the slanted channel of optical screen (because skewed slot is embedded in the inside of described pedestal, namely the process of this imaging system first time projection completes in pedestal), and the height of imaging system directly affects human pilot sight line, therefore imaging system of the present utility model ensure that the sharpness of imaging while effectively reducing height, relative to the secondary reflecting imaging system on existing market, imaging system of the present utility model is the hoisting depth and then affect sight line because of the principle of " triple reflection " not, and then reach height and reproduced image resolution perfectly combine, 4, because vehicle-mounted HUD of the present utility model is provided with light shield at the high order end of skewed slot, and optical screen is in described light shield, therefore, further eliminate the impact of extraneous light aiming screen video picture, ensure the display resolution of the virtual image forming system of triple reflection, 5, by offering radiating groove in the junction of pedestal and mirror reflection surface, ray machine can be dispelled the heat in the course of the work in time, improving job stability and the serviceable life of ray machine.
