Description
Technical field
This utility model relates to a kind of new line display device, particularly relates to one and utilizes windshield glass of automobile to realize coming back
The equipment of display.
Background technology
The English of HUD is Head Up Display, is commonly abbreviated as HUD, means " come back display ", it is also possible to
Be referred to as " head up displays ", when being World War II for solve in fighter-pilot's observation objects driving cabin instrument and with
Inside and outside vision contradiction that track target causes and start research and development.The technology that developed with many wars is the same, and what HUD was initial should
With being exactly on fighter plane, the aircraft equipping HUD the earliest is the Mirage of France.This by electronic building brick, display module,
The comprehensive optoelectronic display device of the composition such as controller and high voltage power supply, can be by letters such as flight parameter, aiming attack, Autonomous test
Breath, with image, the form of character, is projected on passenger cabin dead ahead compound glass by optics.
2003, Bayerische Motorne Werke Aktiengeellschaft became Europe first hand and uses the motor corporation of HUD technology, thus opens vehicle-mounted new line
The beginning of display.Many moneys vehicle of BMW all has been provided with HUD at present, and is carrying out the research and development of night vision system always and answering
With.Navigation system, lane departur warning, band pedestrian identify that the pedestrian of the night vision system of function dodges the information such as warning, can
It is shown on windshield by head-up-display system.Vehicle assembles intelligent vehicle-carried head-up display system, it is also possible to by time
The relevant informations such as speed, rotating speed show in the range of driver front is looked squarely, and effectively prevent driver and cause because of switching sight line
Vehicle accident occurs.
Existing market goes forward to fill high-grade HUD, is primarily present three below shortcoming:
(1) need to customize special windshield glass
Use most HUD designs in the world at present, be in windshield, to add holographic coating or at front
Glass plates semi-transflective reflective film and makes the viewing area of HUD.This method needs in windshield processing and making process
Complete, complex process, it is difficult to promote.
Patent of invention CN102791510B discloses a kind of Vehicle HUD device using multiple lens.The optics of lens belongs to
Property and the layout of reflector be enhanced the driving information image being incident upon in vehicle windscreen with realization, improve definition and distinguish
Do not spend.But this patent of invention needs to increase a semi-transparent semi-reflecting film in the interlayer of windshield, is not direct profit
The new line realizing image with existing windshield shows.
(2) optical projection assembly is positioned at car body
The HUD used in the world, after its optical projection assembly is positioned at meter panel of motor vehicle, the complicated electricity with in car
Road bus is adjacent.This mounting means is not only the maintenance of HUD and brings certain difficulty, and optical projection assembly work
Heat can be produced when making, the circuit bus system of periphery is produced impact, some electronic component time serious, may be caused to work
Abnormal, even to damage, the consequence produced therefrom is difficult to expect.
Patent of invention CN101889234A discloses a kind of projection figure on the transparent windshield HUD of vehicle
The system of shape.This system includes utilizing transparent windshield to realize the multiple reflecting mirror groups shown that come back, whole reflecting mirror
Group is below windshield, after meter panel of motor vehicle.Vehicle body is changed the biggest by this mounting means, it is difficult at the big model in rear dress market
Enclose popularization.
(3) expensive
At present, the standard configuration during middle class HUD is only some import or only a few joint brand middle and high end vehicle/
Optional component, apolegamy price is 28000～50000 yuan.And the high-grade HUD being arranged in deluxe carmodel, accordingly
Original-pack actively or passively infrared night vision system, vehicle deviation early warning, radar vision CAS etc., apolegamy price is higher, typically
It is reached for 10～170,000 yuan.
Utility model content
