Background technology
Graticle in optical observation instrument for aiming at location, reading range finding etc.In rifle gun sight, the stability of graticle, the accuracy of adjusting have vital impact for gun fire accuracy.In traditional rifle gun sight, adopt mechanical type optical axis regulating mechanism to come the position of adjustment aim picture on graticle, to carry out trajectory correction, but mechanical type guiding mechanism is subject to shoot 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 on optical glass, to scribe division line, and the information of its demonstration is just definite when etching, can not change.
Day-night integral observation sighting telescope if the China Patent No. of the applicant's application is ZL201120202494.3, adopts mechanical partition adjusting mechanism, repeatedly in shooting, have the unsettled problem of zero-bit, and graticle only shows cross hairs.Along with the development of Light Electrical technology, the requirement of gun pointing accuracy, information intelligent is improved, 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 defect of existing rifle gun sight division mechanism, the invention provides a kind of electronic division mechanism that makes graticle with the micro-display screen of high-resolution.This mechanism is coupled in rifle gun sight observation optical path by micro-display image and shows division line, utilize the position of video driver circuit intense adjustment division line, whole trajectory makeover process machinery-free part motion, and adopt metal holder to coordinate plastic insulation part closely to fix micro-display screen, improved the stability of graticle under high-intensity oscillation impact condition.Meanwhile, video driver circuit can drive the micro-display screen of high-resolution to show the magnanimity informations such as corresponding division line, word, image according to different situations.
The technical solution adopted for the present invention to solve the technical problems is:
By object lens, relaying image rotation group, eyepiece, form main optical path, between object lens and relaying image rotation group, form image planes one time, between relaying image rotation group and eyepiece, form secondary image planes.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.Micro-display screen and main optical path incident ray lay respectively at semi-transparent semi-reflecting dull and stereotyped both sides, and micro-display screen place plane and semi-transparent semi-reflecting flat board at 45 °, its residing position, with image planes or secondary image planes conjugation.The target picture that the image of micro-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 micro-display screen is nested in plastic insulation part; fixing and locking is in metal holder again; between the display module of PCB backboard projection and plastic insulation part, adopt and leave minim gap, fill with high temperature resistant electronic seal glue in gap, and display module is carried out to buffer protection.Video driver circuit is connected with micro-display screen, controls the information such as micro-display screen output division line, word, image, and the display position of capable of regulating division line on micro-display screen.
Described semi-transparent semi-reflecting flat board can be once between image planes and relaying image rotation group, and micro-display screen graticle image is through semi-transparent semi-reflecting dull and stereotyped transmission or reflection, then after relaying image rotation group, images in secondary image planes, realizes the coupling with target picture.
Described semi-transparent semi-reflecting flat board can also be between secondary image planes and eyepiece, and micro-display screen and secondary image planes are about semi-transparent semi-reflecting dull and stereotyped conjugation.
The invention has the beneficial effects as follows:
The division line position of rifle gun sight is by regulating button control video driver circuit to complete, micro-display screen, semi-transparent semi-reflecting flat board and video driver circuit related in adjustment process are all fixed locked in mechanical hull, there is no movable mechanical parts, solve the zero drift problem that conventional gun gun sight graticle causes because of mechanical parts displacement after shooting vibration, thereby improved fire accuracy.Micro-display screen is installed on plastic insulation part, then is fixed by metal holder, has avoided disturbing because circuit and metalwork directly contact the short circuit or the signal that cause.High-resolution micro-display screen except showing meticulous division line, can also show kinds of words, image information under video driver circuit is controlled, and has increased the transmission capacity of information, reaches intelligentized object.
