Embodiment
There is no interpupillary distance detection function and the defect of automatic regulating function to solve current nearly eye display device, this practicality is new
Type provides a kind of nearly eye display device optical system adjusting apparatus.
In order to be more clearly understood to technical characteristic of the present utility model, purpose and effect, accompanying drawing is now compareed detailed
Illustrate embodiment of the present utility model.
Fig. 2-Fig. 4 is referred to, the utility model includes nearly eye display device 100, and nearly eye display device 100 can be empty
Intend the real helmet.Nearly eye display device 100 includes display screen 10, optical mirror slip 20, adjusting means 30, and adjusting means 30 includes adjusting
Roller 31, geared system 32, shade 33 and support 34 are saved, geared system 32 is connected with optical mirror slip 20 by support 34
Connect, optical mirror slip 20 can do the rotation of small range under the drive of geared system 32.When in use, adjustment regulation roller 31 is
Geared system 32 can be made to drive the small range of optical mirror slip 20 or so to rotate, center of rotation is the center of display screen 10.Relative to water
The dynamic optical mirror slip 20 of translation for adjusting optical system, the life of human eye is more conformed to by center of rotation of the center of display screen 10
Feature is managed, makes display effect more preferably.33 points of shade is left and right two panels anti-dazzling screen 331, and left and right two panels anti-dazzling screen 331 can be buckled
Altogether, under normal usage, left and right two panels anti-dazzling screen 331 is respectively at the two ends of display screen 10, when need carry out light
During the adjustment of system, left and right two panels anti-dazzling screen 331 can play a part of shading after fastening.One end of anti-dazzling screen 331
Semicircular breach is provided with, after left and right two panels anti-dazzling screen 331 fastens, two semicircular breach constitute a circle
Loophole 332.The light that display screen 10 is launched can reach optical mirror slip 20 by loophole 332, then by optical mirror slip
20 are transmitted to exterior space.When two respective geometric centers of optical mirror slip 20 line distance with it is unequal with the interpupillary distance of human eye
When, the right position of optical mirror slip 20 can be adjusted by adjusting adjusting means 31, shade 33 can be with optical mirror slip
20 move together.
Refer to Fig. 5-Fig. 6, during adjustment the line distance of two respective geometric centers of optical mirror slip 20 with
When the interpupillary distance of human eye is equal, the center of display screen 10, the geometric center of optical mirror slip 20 and the pupil of human eye are straight just at one
On line, perfect optical requirement is reached, now display effect is optimal.During regulation, the display centre of display screen 10 is shown
Green target center, on the central horizontal line of display screen 10, the left side of green target center shows the green arrow towards the right, green target
The right side of the heart shows the green arrow towards the left side, the position of green target center is pointed out, other positions do not light.Work as display
During the obstructed remarkable eye pupil hole of the line of the geometric center of center and the optical mirror slip 20 of screen 10, user can pass through loophole
332 observe the arrow of green, can adjust optical system according to the sensing of arrow；When in display screen 10 during adjustment
When the pupil of the heart, the geometric center of optical mirror slip 20 and human eye is in a straight line, the green target center of display centre transmitting
Light can reach human eye by loophole 332.User sees that green target center may know that now optical system regulation reaches
Satisfied accuracy, you can stop regulation, the two ends that shade 33 is adjusted into display screen 10 are normally shown using nearly eye to be filled
Put 100.Using green glow as mark light on the one hand be because green light under dark background than more visible and obvious, it is another
Aspect green glow, without stronger stimulation, it also avoid causing the vision system of people damage to human eye.
Fig. 7-Fig. 8 is referred to, Fig. 7-Fig. 8 respectively illustrates two kinds of embodiments of the present utility model, this practicality shown in Fig. 7
New first embodiment, when adjusting means 30 drives optical mirror slip 20 to move together, display screen 10 is not with optical mirror slip 20 1
Play movement, because optical mirror slip 20 is the center rotating along display screen 10, therefore the emission center of display screen 10 light still
It can be emitted by the geometric center of optical mirror slip 20 with straight line, light does not occur partially when passing through optical mirror slip 20
Turn.The benefit so designed is that display screen 10 can be fixedly installed, and simplifies design and assembling process.This practicality is new shown in Fig. 8
Type second embodiment, when adjusting means 30 drives optical mirror slip 20 to move together, display screen 10 is moved with optical mirror slip 20
Dynamic, such display screen 10 and optical mirror slip 20 keep geo-stationary, therefore the light of the emission center of display screen 10 can still lead to
The geometric center for crossing optical mirror slip 20 is emitted with straight line, and light does not deflect when passing through optical mirror slip 20.Display
As optical mirror slip 20 is moved together display effect can more protruded screen 10, adds the selection of visual angle and the depth of field.
When adjusting beginning, display screen 10 plays test image, the green target center of display centre display of display screen 10, aobvious
On the central horizontal line of display screen 10, the left side of green target center shows the green arrow towards the right, and the right side of green target center is shown
Towards the green arrow on the left side.User wears nearly eye display device 100, and adjusts shade 33 in buckling state, adjusts
Whole adjusting means 31 adjusts the right position of optical mirror slip 20, is adjusted according to the instruction of green arrow, until seeing green
Untill target center.When can persistently see the target center of green in the visual field, it is believed that now the regulation of optical system reaches satisfied
Accuracy, can stop adjusting optical system.The now pupil of the center of display screen 10, the geometric center of optical mirror slip 20 and human eye
It is in a straight line, display effect is optimal.
Compared with prior art, the utility model is by the way of shade 33 and display screen 10 cooperate, can be with
Accurate adjustment optical system, it is ensured that optical system perfect can be shown.It is right again by electronic equipment measurement interpupillary distance relative to needing
Substantial amounts of cost is saved for the device that optical system is adjusted, is conducive to the manufacturing and popularization of equipment.Shading
Device 33 is arranged on the inside of support 34, be able to can both prevent from losing again with convenient for collecting.By being set at the center of shade 33
The light vertical exit at the center of display screen 10 can be made by putting loophole 332, it is ensured that the accuracy of measurement.When unused, shading
Device 33 is received in the both sides of display screen 10, and display is not influenceed.Geared system 32 is adjusted by roller 31 by user, side
Easy row.Playing test image by display screen 10 can point out adjustment person when regulation is to better effects.In display
Screen 10 center show one target center contribute to recognize mark point, around it display green arrow can with convenient use person according to
Arrow direction indication adjusts optical system.
Embodiment of the present utility model is described above in conjunction with accompanying drawing, but the utility model is not limited to
The embodiment stated, above-mentioned embodiment be only it is schematical, rather than restricted, this area it is common
Technical staff is not departing from the utility model objective and scope of the claimed protection situation under enlightenment of the present utility model
Under, many forms can be also made, these are belonged within protection of the present utility model.
