Description

Head mounted display is adjusted structure

Technical field

The utility model relates to a kind of head mounted display and adjusts structure, relate in particular to a kind of can be fast, precise synchronization adjusts the spacing of two display units, to meet the adjustment structure of user's two eye pupil pitchs of holes.

Background technology

The present known employed head mounted display structure of multimedia, as shown in Figure 1, this display device structure includes visual framework 5 and two display units 6.Display unit 6 includes sliding seat 61, display panel 62, frame 63, amplifying lens 64, focal length adjusts assembly 65 and eye distance is adjusted assembly 66.Display panel 62 is fixedly installed on the sliding

seat

61, and 64 of amplifying lenses are fixedly installed on the frame 63.After focal length adjustment assembly 65 passes the screw 611 of sliding seat 61 earlier, pass the screw 631 of frame 63 again, make frame 63 by pivotally connected on sliding seat 61; After the assembling of two display units 6 is finished, utilize eye distance to adjust the screw 612 that assembly 66 passes the screw 51 of visual framework 5 and sliding seat 61 earlier after, can two display units 6 are pivotally connected in visual framework 5.

When adjusting two eye pupil pitchs of holes, adjust assembly 66 drive display unit 6 displacements in visual framework 5 as long as rotate eye distance, promptly can adjust two eye pupil pitchs of holes, to reach the adjustment of watching image frame.But this two eye pupil pitch of holes adjustment are to belong to adjustment out of the ordinary, and asynchronous adjustment is so during two eye pupil pitchs of holes, be difficult for fast, accurately adjust when adjusting.After even two eye pupil pitch of holes adjustment are finished, two display units, 6 positions are also non-to be two correct eye pupil pitchs of holes, therefore the inconvenience that causes the user to use.

The utility model content

Fundamental purpose of the present utility model is to solve above-mentioned known display in the defective of adjusting on the two eye pupil pitchs of holes.The utility model is adjusted the outstanding structure redesign of two eye pupil pitchs of holes with display, allows display when adjusting two eye pupil pitchs of holes, can adjust synchronously, to reach fast, accurately to adjust two oculopupillary spacings.

To achieve these goals, head mounted display of the present utility model is adjusted structure and is comprised: two display units, and framework outside having respectively on each display unit has the pivot connection on the framework outside this; Adjustment unit, comprise two with this pivot connection by pivotally connected driven subassembly, and with the passive component of the synchronous interlock of this two driven subassembly.When this passive component rotates, promptly drive two driven subassemblies and rotate, at this moment, two display units i.e. close the or both sides displacement to passive component synchronously, to adjust user's two oculopupillary spacings.

Embodiment

Relevant technology contents of the present utility model and detailed description, existing conjunction with figs. is described as follows:

Fig. 2, Fig. 3 are that display device structure of the present utility model decomposes and the stereoscopic synoptic diagram.As shown in the figure, head mounted display of the present utility model is adjusted structure and is comprised: two display units 1,1 ' and with two display units 1,1 ' be connected be used to adjust two display units 1,1 ' adjustment unit 2.Utilize adjustment unit 2 can adjust two display units 1,1 ' synchronously, can know the image frame of seeing that two display units are shown so that use corresponding to user's two oculopupillary spacings.

Two display units 1,1 ' on have respectively

outer framework

11,11 '.Outer framework 11,11 ' on have respectively pivot connection 12,12 ', pivot connection 12,12 ' in have flank of thread 13,13 '; Outside framework 11,11 ' inside be assembled with the

display module

14,14 that is used for the show image picture '.

Adjustment unit 2 comprise passive component 21 and symmetrical driven

subassembly

22,22 '.Passive component 21 outside surfaces have ratchet face 211, have joining hole 212 in it, are provided with breach 213 corresponding and that communicate with joining hole 212 at the peristoma place of joining hole 212.The body of rod 221,221 that driven subassembly 22,22 ' have is connected with pivot connection 12,12 ' phase pivot '.Tool flank of thread 222,222 on the body of rod 221, the 221 ' surface ', on the body of rod 221,221 ' one ends, have symmetrical protuberance 223,223 '.When driven subassembly 22,22 ' winding during at joining hole 212, protuberance 223,223 ' promptly is positioned in the breach 213, when passive component 21 was rotated by external force, driven subassembly 22,22 ' promptly was along with rotation, thereby drove two display units 1, the adjustment of 1 ' synchronous shift.Thus, by said modules constitute brand-new can adjust synchronously two display units 1,1 ' the adjustment structure.

Fig. 3, Fig. 4 are the three-dimensional and adjustment action synoptic diagram of display appearance of the present utility model.As shown in the figure, when user's finger is placed on the ratchet face 211 of passive component 21, can promotes passive component 21 and rotate, when passive component 21 rotates, promptly drive two driven subassemblies 22,22 ' rotation; At this moment, two display units 1,1 ' promptly are synchronously to passive component 21 close or both sides displacements, to adjust user's two oculopupillary spacings.

Because each user's two oculopupillary spacings are inequality, thus by adjustment structure of the present utility model, can adjust synchronously fast, accurately two

display units

1,1 of display ', to meet different users's two oculopupillary spacings.

Fig. 5 is the decomposing schematic representation of another kind of display device structure of the present utility model.As shown in the figure, the structure of present embodiment and the structure of Fig. 2 are basic identical, institute's difference be in, utilize linkage unit 3 connect two driven

subassemblies

22,22 '.Have joining hole 31 at linkage unit 3 in it, be provided with breach 32 corresponding and that communicate with joining hole 31 at the peristoma place of joining hole 31, joining hole 31 and breach 32 be used for winding two driven subassemblies 22,22 '; 22,22 windings of two driven subassemblies two displays 1,1 ' pivot connection 12,12 ' after, with two passive components 4,4 ' respectively be installed in two driven subassemblies 22,22 ' an end on.Passive component 4,4 ' on have respectively ratchet face 41,41 '.Rotating any one passive component 4 or 4 ' time, interlock two driven subassemblies 22,22 ' rotate synchronously simultaneously, realize adjusting simultaneously synchronously two displays 1,1 ' spacing, to meet different users's two oculopupillary spacings.

The above only is a preferred embodiment of the present utility model, be not so promptly limit claim of the present utility model, the equivalent structure transformation that every utilization the utility model instructions and accompanying drawing content are done, or directly or indirectly be used in other relevant technical field, all in like manner be included in the claim of the present utility model.
