Description
Technical field
The present invention relates to new line field of display technology, especially a kind of light path system of head-up display.
Background technique
Currently, with the development of auto industry active safety, to the display of on-vehicle safety information, more stringent requirements are proposed,
Traditional on-vehicle information-such as speed, revolving speed, fuel liquid level are often shown on instrument board, and user, which need to bow, can just see
Information, brings some potential safety problems, in existing partial automobile, increases HUD(head-up display), HUD will be on instrument board
Speed, revolving speed, fuel liquid level, navigation information and warning message (such as tire pressure be decreased or increased, machine oil indicator light) etc. throw
It penetrates on the windshield, driver can directly be not required to bow, and during normal driving, head-up front energy acquisition speed is led
The information such as boat information, ADAS and warning message (such as tire pressure be decreased or increased, machine oil indicator light), improve car steering
Security performance.
In existing HUD, image information is issued by image display device (PGU), image beam passes through even mating plate, then passes through
Two reflecting mirrors are crossed, so that image is projected on shield glass, form the virtual image of image in the front of front windshield,
Driver can observe speed, navigation information, ADAS of automobile etc. constantly, and HUD is mounted on position of driver, due to image
Display device volume itself is larger, and the image information that image display device is launched is directly over even mating plate out, is passing through
Reflecting mirror is sent to front windshield, since image display device structure is larger, and the image emission port of image display device
It needs to be directly toward even mating plate, in order to which the virtual image for reflexing to image display device in front of front windshield is big, needs image aobvious
The image emission port and the distance between even mating plate of showing device are sufficiently large, in existing central control system for installing HUD
Volume reduce, the image emission port of the image display device in HUD reduces at a distance from even mating plate, so that being projected in front
The virtual image formed in front of wind glass is smaller, on-vehicle information can not be accurately seen clearly during driver drives vehicle, so that driver
Also need the on-vehicle information checked on instrument board of bowing again.
Summary of the invention
Goal of the invention of the invention is: existing for the prior art with the volume for being used to install HUD in central control system
Reduce, the virtual image that HUD is in front of front windshield is smaller, can not accurately see vehicle-mounted letter in driver's forming process clearly
The problem of breath, provides a kind of light path system of head-up display.
To achieve the goals above, the technical solution adopted by the present invention are as follows:
A kind of light path system of head-up display, including image display device, the first reflecting mirror, even mating plate, the second reflecting mirror and
Third reflecting mirror, the light that described image display device issues are transferred to first reflecting mirror, and first reflecting mirror is by light
Line is transferred to the even mating plate, and light is transferred to second reflecting mirror through the even mating plate, and second reflecting mirror is by light
Line reflection is to the third reflecting mirror.
As this practical preferred embodiment, the light path system of head-up display further includes shell, described image display device,
First reflecting mirror, the even mating plate, second reflecting mirror and the third reflecting mirror are fixed at the shell
It is interior, the light of described image display device issue select, the light of the reflection point of first reflecting mirror and the even mating plate passes through
Point is triangularly arranged.
As a preferred solution of the present invention, first reflecting mirror is plane mirror or concave mirror, and the second reflecting mirror is plane
Mirror or concave mirror, the third reflecting mirror are plane mirror or concave mirror, and plane mirror is the conventional application of reflecting mirror, and concave mirror can
Increase the area in the virtual image in the front of front windshield, increases the display of image information.
As a preferred solution of the present invention, the first mounting bracket, the second mounting bracket, are fixedly installed in the shell
Three mounting brackets and the 4th mounting bracket, first reflecting mirror are fixed in first mounting bracket, the even light
Piece is fixed in second mounting bracket, and second reflecting mirror is fixed in the third mounting bracket, institute
It states third reflecting mirror to be fixed in the 4th mounting bracket, described image display device is fixed at the shell bottom
Portion enables each reflective mirror and even mating plate to be stably mounted to enclosure interior, increases the integrally-built stability of HUD.
As a preferred solution of the present invention, described image display device at a distance from first reflecting mirror for 40mm~
120mm, first reflecting mirror are 40mm~120mm at a distance from the even mating plate, between two components that this place refers to away from
From for light between two components with a distance from.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, the first reflecting mirror is increased between image display device and even mating plate, the band image that image display device is launched is believed
The light of breath reflexes to even mating plate by the first reflecting mirror, and light is through even mating plate to the second reflecting mirror, and the second reflecting mirror is by light
Light is transferred on front windshield by line reflection to third reflecting mirror, third reflecting mirror, guarantees what image display device issued
Light source virtual image formed by the front of front windshield is sufficiently large so that driver do not have to bow can clear view to alarm signal
Breath, navigation information etc. so that guarantee light that image display device is launched enter even mating plate apart from it is enough while, image
The distance between display device and even mating plate reduce, so that HUD internal structure is compact, reduce the integrally-built volume of HUD.
