Description

A kind of intelligent glasses of adjustable contrast

Technical field

This utility model relates to intelligent glasses technical field, especially relates to the intelligent glasses of a kind of adjustable contrast.

Background technology

Intelligent glasses, also referred to as smart mirror, refer to as smart mobile phone, there is independent operating system, the program that can be provided by software houses such as user installation software, game, voice can be passed through or action has manipulated adding schedule, digital map navigation and good friend's interaction, shooting photo and video and friend launches the functions such as video calling, it is possible to be realized the general name of such class glasses that wireless network accesses by mobile communication network. Compared with common smart mobile phone, intelligent glasses have information can look squarely, without taking hands, the advantage such as more miniature receives more and more attention.

The basic structure of intelligent glasses is made up of micro projector, photographic head, controller (including sensor, storage transmission equipment, controlling equipment etc.). Wherein, micro projector, common name " prism ", be equivalent to a small-sized head up displays (HUD), mainly light is thrown on one piece of radiation shield, then reflex to human eyeball by one piece of convex lens, it is achieved so-called " one-level amplification ", a sufficiently large virtual screen is formed, it is possible to show simple text message and various data before human eye. Existing prism be fit successively in a right-angle surface of polarization splitting prism quarter-wave plate, reflection enlarging lens form, this prism has the disadvantage in that under any light intensity (dim or bright) environment, the contrast of the light that extraneous incident light sends with display is fixing, it is impossible to adapt to the demand of different light environment.

In view of this, special proposition this utility model.

Utility model content

The purpose of this utility model is in that to provide the intelligent glasses of a kind of adjustable contrast, to solve to there is the technical problem that cannot regulate contrast in prior art.

The intelligent glasses of the adjustable contrast that this utility model provides, including micro projector, lens body and the display controller being connected with described lens body, linear polarizer; Described micro projector is made up of polarization splitting prism;One right-angle surface of one corner cube prism of described polarization splitting prism is fitted with quarter-wave plate, reflection enlarging lens successively, and a right-angle surface of another corner cube prism is just to described linear polarizer; Face relative with quarter-wave plate one of them described on described polarization splitting prism connects described display controller;

Described linear polarizer is rotatable, and just same right-angle surface to described polarization splitting prism all the time in rotary course.

Compared with prior art, above-mentioned intelligent glasses of the present utility model is additionally arranged a linear polarizer, and this linear polarizer can rotate, therefore the ambient light intensity entering human eye from the direction can be regulated, thus regulating the contrast of its light sent with intelligent glasses itself, adapt to varying environment demand.

The all right Optimal improvements further of above intelligent glasses:

Preferably, described linear polarizer is tabular, and hinged with described lens body.

When linear polarizer is tabular, the P light that the external world can pass through polarization splitting prism is more, and it is just wider with the contrast range of lens body light, and the selection space of wearer is just bigger. Herein hinged can be any articulated elements that can realize in prior art.

Preferably, described linear polarizer and described lens body removably connect.

User can select not use the function regulating contrast, linear polarizer is removed, reduces the heavy burdens.

Embodiment 1

The intelligent glasses of a kind of adjustable contrast, as illustrated in fig. 1 and 2, including micro projector, lens body and the display controller 1 being connected with lens body, linear polarizer 5; Micro projector is made up of polarization splitting prism 2; One right-angle surface of one corner cube prism of polarization splitting prism 2 is fitted with quarter-wave plate 3, reflection enlarging lens 4 successively, and a right-angle surface of another corner cube prism is just to linear polarizer 5; Face relative with one of them quarter-wave plate 3 on polarization splitting prism 2 connects display controller 1; Linear polarizer 5 is tabular, and hinged with lens body, and by this articulated structure, linear polarizer 5 can rotate, and just same right-angle surface to polarization splitting prism 2 all the time in rotary course. Linear polarizer 5 and lens body removably connect.

The principle that above-mentioned intelligent glasses regulates contrast is as follows:

As shown in Figure 3, the light that display controller 1 (i.e. the image source of intelligent glasses) sends P light (i.e. light shown in double-head arrow) after the spectro-film of polarization splitting prism 2 loses through S (i.e. light shown in single arrow) luminous reflectance, P light is after quarter-wave plate 3 and reflection magnifier 4, become S light then through quarter-wave plate 3, after arriving the spectro-film of polarization splitting prism 2, be reflected into human eye 6. With the ambient light intensity that enters human eye from linear polarizer 5 bigger time for initial condition, as shown in Figure 3, in order to improve contrast, need to change the light intensity of ambient light, so being additionally arranged linear polarizer 5, linear polarizer 5 allows the light transmission of direction vibrations, namely sequentially passes through linear polarizer 5, polarization splitting prism 2, extraneous P light enters human eye 6, and now the light intensity of ambient light is maximum. When ambient light is crossed strong, the ambient light through polarization splitting prism received due to position of human eye is P light, so rotational line polaroid 5 is to making P light not pass through, as shown in Figure 4, this figure is the ray plot after the linear polarizer 90-degree rotation of Fig. 3 state; When ambient light is not as strong time, it is possible to allow P too much pass through by rotational line polaroid 5.

Though it addition, the linear polarizer in above-described embodiment is tabular, but its cross section can be arbitrary shape, for instance circular, square or other is irregularly shaped.

Last it is noted that various embodiments above is only in order to illustrate the technical solution of the utility model, it is not intended to limit; Although this utility model being described in detail with reference to foregoing embodiments, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein some or all of technical characteristic is carried out equivalent replacement; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of this utility model.
