Cabinet inside is provided with control assembly, display module, optical module and a player module, the control assembly
One control of intelligent terminal, control of intelligent terminal are powered by power module, and control of intelligent terminal is master controller, and intelligent control is whole
End connection display module and player module；
Display module is controlled by control assembly, the form face face optical module of display module；
Optical module includes an optical lens module and a speculum, and speculum is installed on the output of optical lens module
End, puts, transparent screen is installed on reflection end face one end of speculum, optical lens module between speculum and horizontal plane in 45 degree
Incidence angle one end of face speculum.
As preferable technical scheme, the optical lens module and speculum are installed in machinery by a support,
Screw is provided with support, support is installed on mechanical inwall by the way that screw is detachable.
The beneficial effects of the utility model are：The utility model is using the double aobvious technology for detection visual conditions of a screen, realization pair
Complexity regards the real simulation (such as misty rain low contrast low-light (level)) of luminous environment；Realized using the double aobvious technologies of a screen to hyperopia and myopia
The synchronous detection with screen of same machine, effectively improve detection efficiency；And extra screening annexa oculi is saved, by controlling the logical of transparent screen
Power off to control the whether transparent of screen and transparent region.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), except non-specifically chatting
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, control assembly, display module, optical module and a player module are installed inside cabinet 1；
In the present embodiment, control assembly uses computer main board 4, and computer main board 4 is powered by power module, computer main board 4
For master controller, computer main board 4, which connects display module and player module, control assembly, can also use computer or smart mobile phone
Or tablet personal computer etc.；
In the present embodiment, player module uses transparent screen, but can also use other structures during actual use, as long as real
The structure of existing automatically controlled control transparency can be applied in the utility model.
In the present embodiment, display module uses a display screen 5, and the form on display screen 5 is controlled by computer main board 4,
The form face face optical module of display screen 5, computer main board be PC of the prior art master control borad, the big portion of display module
Divide and use display screen, but also other many display modules, also it can apply in the utility model, as long as can be real
Now show and can be used in the utility model；
Optical module includes an optical lens module 6 and a speculum 7, speculum 7 are installed on the defeated of optical lens module 6
Go out end, put between speculum 7 and horizontal plane in 45 degree, transparent screen 3 is installed on reflection end face one end of speculum 7, optical lens
Incidence angle one end of the face speculum of mirror assembly 6.
Optical lens module 6 is conventional image amplifier, the image on display screen through optical lens module amplification, then
By the reflection of speculum, by the image transmitting on display screen to transparent screen.
Using optical lens module as image amplifier, in real life, also many light in the present embodiment
Amplifier, therefore other optical amplifiers also may be selected in the utility model, as long as the structure that light amplifies can be applied.
In the present embodiment, the reflection angle of speculum 7 can be adjusted conveniently, and the putting position of transparent screen can be used for regulation anti-
Penetrate the reflection angle of mirror so that reflected image being capable of face transparent screen.
In the present embodiment, it can be used cooperatively with visual environment builder so that when equipment is used for vision-based detection, testee
The image on transparent screen that two eyes are seen is different.
In the present embodiment, optical lens module 6 and speculum 7 are installed in machinery by a support, are set on support
There is screw, support is installed on mechanical inwall by the way that screw is detachable, and the installation of optical lens module and speculum can pass through
Support is dismantled, and is also mountable to position different in cabinet, selects optimal position to complete installation.
Device interior light path principle is：Long sight detects and near-sighted detection passes through the positive transparent screen of equipment body with image
Realize, the switching of antimetropia detection is controlled by computer main board in equipment body.
When switching to distant vision to detect, mainboard control transparent screen is powered and transparent screen is changed into transparent, while opens display
Screen imaging, display screen imaging projects 45 degree of corner reflectors through optical module, then projects transparent screen through speculum.It is detected and uses
The projection imaging can be seen in family, receives detection；
When switching near vision to detect, mainboard control transparent screen power-off makes transparent screen be changed into White-opalescent, simultaneously will
Imaging is shown in the screen, and being detected two eyes of user can open simultaneously, and transparent screen is divided into two pieces, and the display content of both sides is equal
Difference, if tested eyes are left eye, now there is image in the left screen of transparent screen, and without image on the screen of right side, due to
Close visual environment builder to use, left eye can see detection image, and right eye is then it is seen that the transparent screen without image, is received with this
Detection.
The beneficial effects of the utility model are：
1st, detection while hyperopia and myopia are carried out in same equipment is realized, is originally told somebody what one's real intentions are so as to effectively improve to apply
The equipment application value of technology.
2nd, using electrically controlled transparent material as form, by the power on/off to left and right form come control the transparent of form with
It is no, the dependence to aid has not only been broken away from, more ensure that eyesight status of the bore hole in detection that be blocked is unaffected.From
And make it that detected value is more objective and credible.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work, should all cover within the scope of protection of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
