Background technology
Graticle is used for aiming location, reading range finding etc. in optical observation instrument.In the rifle gun sight, the stability of graticle, the accuracy of adjusting have vital impact for the gun fire accuracy.Adopt the mechanical type optical axis regulating mechanism to come the position of adjustment aim picture on graticle in traditional rifle gun sight, to carry out the trajectory correction, but the mechanical type guiding mechanism is subject to shoot the vibratory impulse displacement, causes repeatedly shooting rear zero drift, and point of impact departs from former aiming point.In addition, traditional graticle adopts chemical etching process to scribe division line at optical glass, and the information of its demonstration is just definite when etching, can not change.
China Patent No. such as the applicant's application is the day-night integral observation sighting telescope of ZL201120202494.3, adopts mechanical partition adjusting mechanism, repeatedly have the unsettled problem of zero-bit in the shooting, and graticle only shows cross hairs.Along with the development of ray machine power technology, to the requirement raising of gun pointing accuracy, information intelligent, above-mentioned conventional gun gun sight division mechanism stability problem not good and that demonstration information is limited has to be solved.
Summary of the invention
For overcoming the defective of existing rifle gun sight division mechanism, this patent provides a kind of electronic division mechanism that makes graticle with the little display screen of high-resolution.This mechanism is coupled to little display image in the rifle gun sight observation optical path and shows division line, utilize the position of video driver circuit intense adjustment division line, whole trajectory makeover process machinery-free spare motion, and adopt the metal holder to cooperate plastic insulation spare that little display screen is closely fixed, improved the stability of graticle under high-intensity oscillation impact condition.Simultaneously, video driver circuit can drive the little display screen of high-resolution according to different situations and shows the magnanimity informations such as corresponding division line, literal, image.
The technical scheme that its technical problem that solves this patent adopts is:
Consist of main optical path by object lens, relaying image rotation group, eyepiece, between object lens and relaying image rotation group, form image planes, form the secondary image planes between relaying image rotation group and the eyepiece.In main optical path, insert one and optical axis semi-transparent semi-reflecting flat board at 45 °, the one side plating spectro-film of this flat board, another side plating high-transmission rate film.Little display screen and main optical path incident ray lay respectively at semi-transparent semi-reflecting dull and stereotyped both sides, and plane, little display screen place and semi-transparent semi-reflecting flat board are at 45 °, and its residing position is with image planes or secondary image planes conjugation.The target picture that the image of little display screen output becomes with object lens is coupled to a light path by semi-transparent semi-reflecting flat board, and enters human eye through eyepiece.
The PCB backboard of described little display screen is nested in the plastic insulation spare; fixing and locking is in the metal holder again; adopt between the display module of projection and plastic insulation spare on the PCB backboard and leave minim gap, fill with high temperature resistant electronic seal glue in the gap, and display module is carried out buffer protection.Video driver circuit is connected with little display screen, controls the information such as little display screen output division line, literal, image, and the display position of capable of regulating division line on little display screen.
Described semi-transparent semi-reflecting flat board can be once between image planes and the relaying image rotation group, and little display screen graticle image is through semi-transparent semi-reflecting dull and stereotyped transmission or reflection, pass through again relaying image rotation group after, image in the secondary image planes, realize the coupling with the target picture.
Described semi-transparent semi-reflecting flat board can also be between secondary image planes and eyepiece, and little display screen and secondary image planes are about semi-transparent semi-reflecting dull and stereotyped conjugation.
The beneficial effect of this patent is:
Finish by regulating the button control video driver circuit division line position of rifle gun sight, little display screen, semi-transparent semi-reflecting flat board and video driver circuit related in the adjustment process are all fixed locked in mechanical hull, there is not movable mechanical parts, solve the zero drift problem that conventional gun gun sight graticle causes because of the mechanical parts displacement after the shooting vibration, thereby improved fire accuracy.Little display screen is installed on the plastic insulation spare, is fixed by the metal holder again, has avoided disturbing because circuit and metalwork directly contact the short circuit or the signal that cause.High-resolution little display screen except showing meticulous division line, can also show kinds of words, image information under video driver circuit control, increased the transmission capacity of information, reaches intelligentized purpose.
