Other well-known parts of the utility model, such as shell, connect wires, the part shapes, structure such as supporting element
It is the prior art, is not described in detail herein.
For the guarantee of picture quality under cramped construction: under normal circumstances, 500 front of driver of passenger car can all have convex
The console or instrument desk risen, this segment space limits putting for head-up display device, if further compressing imaging unit
200 and second the distance between the reflecting optics 400, then the image-forming range of head-up display device is affected.This is practical new
The console or instrument desk of protrusion is utilized in type, and imaging unit 200 is tilted down and is put, and utilization lays flat or approaches and lays flat
The first reflecting optics 300 imaging ray is reflected towards the second reflecting optics 400, it is good that such design method brings two o'clock
Place: one, the downward inclination angle (the second angle) of the first reflecting optics 300 further decreased, this reduces the height of complete machine；
Two, for the second reflecting optics 400, the off-axis angle between incident ray and emergent ray and primary optical axis is further reduced
It spends, in optical path model as shown in Figure 3, off-axis angle only has 10 ° or so, thus very close ideal image condition.It improves
The image quality of second reflecting optics 400, to provide relatively sharp head-up display device imaging for driver.
On the one hand, the present embodiment uses multiplexed light structure, has feature compact-sized, that projected image is remote；Another party
Face, the present embodiment are just casting anti-close-coupled optical texture and imaging unit 200,300 and of the first reflecting optics by unique
The modular design of second reflecting optics 400 subtracts to the maximum extent under the premise of guaranteeing to come back display image and visual angle quality
The small volume of head-up display device.The head-up display device of the utility model has ultra-thin fuselage, particularly suitable for designing
Automobile through being formed or having dispatched from the factory, is not required to dig in front of instrument desk as head-up display device in the prior art
Hole, so that it may which the imaging effect for reaching head-up display device in the prior art reduces the installation threshold of head-up display device, tool
There are widely market prospects.
Embodiment 2
The present embodiment is roughly the same with embodiment 1, the difference is that, the first reflecting optics 300 are concave reflection eyeglass,
Second reflecting optics 400 are plane reflection eyeglass or concave reflection eyeglass or are convex refractive eyeglasses.
Embodiment 3
Since such head-up display device is in a manner of installing additional, it is placed in above the instrument desk in front of driver,
If reflecting optics would be possible to extraneous sunlight, street lamp light reflexing to driver's eyes without effective shade,
It brings and dazzles the eyes problem, seriously affect the traffic safety of driver.
For the utility model by the way that concave mirror inner surface is coated with reflectance coating, concave mirror is opaque, and effectively blocks
The light of external light source directive plane mirror, solves glare problem.
In order to solve the first reflecting optics 300 and the second reflecting optics 400 for the external environments light such as sunlight, street lamp
Reflection, caused by glare of driver problem, the second reflecting optics 400 are towards imaging unit 200 and the first reflecting optics 300
It is coated with reflectance coating on one side.Further, the first reflecting optics 300 towards imaging unit 200 and the second reflecting optics 400 one
Face can also be coated with reflectance coating.
It is edge-on and lighttight as shown in figure 4, when external light source is from upper front part the first reflecting optics 300 of directive
Two-mirror piece 400 is effectively light-blocking.As shown in figure 5, when external light source is from top the first reflecting optics 300 of directive, lay flat or
The light of the direction will not be reflected towards to 500 eyes of driver close to the first reflecting optics 300 laid flat.As shown in fig. 6, when outer
Boundary's light source is laid flat or will not should close to the first reflecting optics 300 laid flat on rear side of the top when the first reflecting optics 300 of directive
The light in direction is reflected towards 500 eyes of driver.
Since the second reflecting optics 400 are edge-on downwards towards driver 500 with the inclination angle of third angle, and the first reflecting mirror
Piece 300 is opaque, effectively blocks the light of the second reflecting optics of external light source directive 400, thus solve glare problem, nothing
Light-baffling device, reduced small product size must in addition be increased.
Embodiment 4
In order to adapt to the height of sighting line of different height drivers 500 and different sitting posture drivers 500, the utility model is special
Benefit further includes the picture altitude adjustment structure for adjusting image height, and picture altitude adjustment structure is arranged in the second reflecting optics
400 and/or first on reflecting optics 300.
As shown in Figure 1, picture altitude adjustment structure is arranged on the second reflecting optics 400, for adjusting third angle
Size.Specifically, picture altitude adjustment structure includes shaft 600 and manually or electrically regulating mechanism.Shaft 600 is arranged second
400 upper end of reflecting optics or intermediate position are made by being located at the manually or electrically regulating mechanism of 400 lower end of the second reflecting optics
Second reflecting optics, 400 lower end can be moved forward and backward, thus change the catoptric imaging ray angles degree of the second reflecting optics 400, warp
After crossing the secondary reflection again of the first reflecting optics 300, the imaging ray position for being reflected into windshield 100 changes, Jin Ergai
Become the image height of the head-up display device.
Certainly, in the other embodiments of the application, picture altitude adjustment structure also be can be set in the first reflecting optics
On 300, for adjusting the size of the second angle.Specifically, picture altitude adjustment structure is shaft 600.The setting of shaft 600 is the
Any end of one reflecting optics 300, while manually or electrically regulating mechanism is set in the other end of the first reflecting optics 300,
Can move up and down 300 one end of the first reflecting optics, thus change the transmitting imaging ray angle of the first reflecting optics 300,
Achieve the purpose that adjust head-up display device image height.
The present embodiment further includes front-rear position regulating device, for adjust imaging unit 200 and the first reflecting optics 300 it
Between distance, front-rear position regulating device be arranged on imaging unit 200 and/or the first reflecting optics 300.Picture altitude is adjusted
Structure can make head-up display device further adapt to the inclination angle of different windshield 100 of different vehicle, thickness, refractive index band
The ghost problems come.
On the one hand the utility model uses the light channel structure of close-coupled, the second reflecting optics 400 roll and another close
The second horizontal positioned reflecting optics 400, it is light-blocking to be effectively utilized 400 self structure of the second reflecting optics, prevents ambient
It is caused to dazzle the eyes problem；On the other hand trans- compact optical structure, the second reflecting optics 400 and imaging are just being cast using unique
Unit 200 dips down the setting of inclined, efficiently utilizes the structure space limit of 500 front console of driver and instrument desk
System, and under the premise of guaranteeing head-up display device quality and angular field of view, head-up display device is reduced to the maximum extent
Thickness and volume, created condition for head-up display device in popularizing for storage car market, bring significant economic effect
Benefit and social benefit.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
It, in specific embodiments and applications can be with many changes may be made, as long as these variations are without departing from this with novel thought
The design of utility model, belongs to the protection scope of the utility model.
