Description
Technical field
The utility model is related to intelligent terminal technical field, more particularly to a kind of vehicle-mounted head-up display.
Background technology
Head-up display（HUD, Head Up Display）, it is early stage application flight supplementary instrument on aircraft at present on aircraft.It is flat
Depending on be meant that pilot need not bow just it can be seen that he need important information.The head-up display army of appearing in earliest
With on aircraft, reduction pilot is bowed and checks the frequency of instrument, it is to avoid notice is interrupted and lost to situationawareness
（SituationAwareness）Grasp.Due to head-up display convenience and flight safety, airliner can be improved
Also numerous and confused follow-up is installed.
With the development of science and technology, head-up display is also used on automobile more and more.Looking squarely on automobile
Display can be by important running information, such as speed, engine revolution, oil consumption, tire pressure, navigation and external smart machine
Information be displayed in real time on front windshield in the visual field of driver, so that driver need not bow, it is possible to see
To running information, so as to avoid dispersion to the notice of road ahead, potential driving hidden danger is eliminated；It is additionally, since projection
When the virtual image fall immediately ahead of car, the time that driver adjusts visual focal length will shorten, safer for driver.Together
When so that driver need not adjust eyes between instrument in the road in an observation distant place and nearby, can avoid the fatigue of eyes,
Driving can greatly be strengthened entirely and driving experience is improved.
As shown in figure 1, existing head-up display is typically made up of ray machine, radiation shield, imaging screen, light beam is projected from ray machine
To radiation shield, then imaging screen is reflexed to by radiation shield, then human eye is reflexed to by imaging screen, form catoptric arrangement twice, imaging away from
Close to（0.5~1.0m）.Meanwhile, as shown in Fig. 2 during use, before head-up display need to be positioned over vehicle windscreen
In space, due to the narrow space before vehicle windscreen, so as to limit the main frame length of head-up display, light beam is caused to pass through
After crossing two secondary reflections, imaging at a distance cannot be still obtained.Therefore, existing head-up display image-forming range is nearer, easily divides
Notice of the driver to front road conditions is dissipated, traffic safety is influenceed.
The content of the invention
Technical problem to be solved in the utility model is, there is provided a kind of vehicle-mounted head-up display, can be by light beam
Triple reflection effectively extend imaging optical path.
