Description
Technical field
The utility model relates to a kind of easy video eyeglasses eyesight adjustment device, can be applicable to the focus adjusting mechanism of the visual system such as video eyeglasses, virtual implementing helmet.
Background technology
Video eyeglasses/intelligent glasses is one of the major equipment of man-machine interaction, augmented reality, the glasses of all the type all be unable to do without opticator, the effect of this part is amplified by the image on micro-display screen, and by image projection on retina, and then be presented in large-screen image in beholder's eye.Determine whether beholder can know the principal element seeing image: one is that optical system has good imaging capability, and two is eye conditions that optical system can adapt to different crowd preferably.First factor depends mainly on the Design and manufacture of optical system, and second factor is except outside the Pass having with optical system, relevant with the mechanical adjusting mechanism of assisting toward contact.
The different users of video eyeglasses has different eye conditions, distinguish with eyesight, roughly can be divided into myopia, normal, long sight (presbyopic) three kinds, for same optical system, in unregulated situation, almost cannot meet the demand from myopia to long sight crowd.Therefore be necessary for that optical system is auxiliary adds mechanical adjusting mechanism, for regulating different diopters.
The eyesight adjustment device volume that current most video eyeglasses adopts is comparatively large, even in order to reduce volume weight, also usually dispenses this governor motion.Existing visual system lens barrel focusing system usually have: screw thread rotation focusing system, chute-type focusing system etc.Screw thread rotation focus adjusting mechanism is transformed to straight line precession amount by rotational action, but often needs to add lubricant reduction friction in this mechanism, and this can cause the pollution of optical system usually.Chute-type focus adjusting mechanism is developed by cam mechanism, moves slip pin do straight line precession by rotary chute endless belt, but this type mechanism structure is slightly aobvious complicated at present, and volume is also larger, and reducing weight with the loss of weight of video eyeglasses contradicts.
Utility model content
The technology of this practicality is dealt with problems: the deficiency overcoming existing chute-type focus adjusting mechanism, provides a kind of easy video eyeglasses eyesight adjustment device, more simply, is easier to produce, to reduce assembly process, improves working (machining) efficiency and reduce costs.
The technical solution of the utility model: a kind of easy video eyeglasses eyesight adjustment device, comprising: lens barrel shell, objective table, optical tubes, spacer ring, dustproof window sheet and trim ring, described eyesight adjustment device be connected with video eyeglasses by four mounting holes of lens barrel outer shell outer wall, fixing, all the other five parts and objective table, optical tubes, spacer ring, dustproof window sheet and trim ring are all inner at lens barrel enclosure cavity, lens barrel shell inner cavity is stepped cylindrical cavity, and top wall thickness is thinner, the rectangular channel that bottom is established, just in time objective table is made to do longitudinal sliding motion with the rectangular configuration clearance fit of described objective table outer wall, the top of objective table is cylindrical cavity, the internal thread of the inner cylinder face of objective table forms with the external thread of outer wall at the bottom of described lens barrel and is threaded, the protruding platform that lens barrel outer wall is established is limited in the chute of described lens barrel shell shell wall, lens barrel only can be rotated, spacer ring is provided with between described optical tubes top and described dustproof window sheet, dustproof window sheet is fixed on lens barrel shell by described trim ring.
The shell wall of described lens barrel shell is provided with chute, has opening above chute, is fit into facilitate the protruding platform of optical tubes outer wall.
Described lens barrel shell shell wall is provided with four mounting holes, is convenient to be installed on by whole eyesight adjustment device in other structures on video eyeglasses.
Described lens barrel shell shell wall is provided with groove, carries out buckle-type be connected with trim ring.
Described objective table outer wall shape is consistent with lens barrel outer casing inner wall.
Be provided with perforate bottom described objective table, its shape is consistent with the display Source size that size and video eyeglasses adopt.
Described objective table inwall is internal thread, matches with the external thread of optical tubes.
Described lens barrel shell, objective table, optical tubes, spacer ring and trim ring are plastic member or hardware.
Moved around lens barrel housing center along sliding tray by the protruding platform promoting optical tubes outer wall, rotary motion is threaded connection and conducts to objective table by optical tubes, objective table is due to the restriction of lens barrel outer casing inner wall, rotary motion is converted to rectilinear motion, the relative distance reached between objective table and optical tubes regulates, thus realizes diopter adjustment.
The utility model advantage is compared with prior art: improve chute governor motion (cam wheel adjustment mechanism) and simplify, the straight line precession rotating and regulate is achieved by less part, simplify difficulty of processing, to reduce assembly process, improve working (machining) efficiency and reduce costs.
