The dust-proof assembly 400 is disposed between the lens set 300 and the screen 100 such that a sealed cavity is formed between the screen 100 and the lens set 300.

Specifically, the screen 100 may be composed of two display screens, and the two display screens may be hinged together through a rotating shaft or the like, so that the positions of the display screens can be adjusted along with the difference of the interpupillary distances of the wearer, and further, the relative positions of the two supports can be changed. The lens barrel 110 may be directly adhered to a side surface of the screen 100 by glue or the like, and a cavity is formed inside the lens barrel 110 to facilitate connection between the holder 200 and the lens barrel 110. The lens set 300 includes a lens and a film, a cavity for mounting the lens is formed in the frame 200, and the lens and the frame 200 can be clamped or bonded by glue.

When this optical structure used, dustproof subassembly 400 formed sealed chamber respectively at screen 100 and lens group 300 support 200 to when the circulation of air, the unable sealed intracavity that gets into of air, the dust in the air just also is difficult to get into sealed intracavity, and then reduces impurity interference lens such as dust to the refraction of light, with the experience that effectively improves the user and feels.

Referring to FIG. 1, in some embodiments of the present application, a dust seal assembly 400 includes a see-through plate 410. The see-through plate 410 covers a cross section of the lens barrel 110. The sealed cavity includes a first cavity and a second cavity, the first cavity is formed between the see-through plate 410 and the lens assembly 300, and the second cavity is formed between the see-through plate 410 and the screen 100.

Referring to fig. 1, the space between the lens assembly 300 and the screen 100 is divided into a first cavity and a second cavity by the see-through plate 410, and the first cavity and the second cavity are both sealed, so that the possibility of air entering is effectively reduced, and the possibility of dust and other impurities attaching to the screen 100 or the lens assembly 300 can be reduced.

Referring to fig. 1, in some embodiments of the present application, a see-through plate 410 is provided within the lens barrel 110. The perspective plate 410 is arranged in the lens barrel 110, the outer peripheral wall of the perspective plate 410 is attached to the inner side wall of the lens barrel 110, the support 200 and the lens group 300 are connected, at the moment, the first cavity is formed by enclosing the inner side wall of the perspective plate 410, the inner side wall of the lens barrel 110 and the inner side wall of the screen 100, and the second cavity is formed by enclosing the outer side wall of the perspective plate 410, the inner side wall of the support 200 and the inner side wall of the lens group 300.

Referring to fig. 1, in some embodiments of the present application, a see-through plate 410 is connected to an end surface of an end of the lens barrel 110 away from the screen 100. At this time, the perspective plate 410 directly seals the cavity in the lens barrel 110, that is, the cavity in the lens barrel 110 is the first cavity, and the support 200 is connected with the perspective plate 410 to enclose the second cavity. The installation position of the specific see-through plate 410 may be selected according to the actual installation space.

Referring to fig. 1, in some embodiments of the present application, a see-through plate 410 is bonded to a lens barrel 110. When the perspective plate 410 is installed, the perspective plate 410 and the lens barrel 110 are bonded together by glue, and the glue can effectively fill a gap between the perspective plate 410 and the lens barrel 110, so that a sealed first cavity and a sealed second cavity are smoothly formed.

Referring to fig. 1, in some embodiments of the present application, the perspective plate 410 is made of glass. Specifically, the see-through plate 410 may be made of a glass plate having a good light transmission effect, and the light passing through the glass plate has a small loss and a weak degree of refraction or reflection, so that the light generated by the screen 100 can be smoothly refracted through the lens assembly 300.

Referring to FIG. 1, in some embodiments of the present application, the dust guard assembly 400 further includes a dust guard 420. The dust-proof member 420 is disposed circumferentially along the bottom surface of the bracket 200, and the dust-proof member 420 is connected to the bracket 200 and the lens barrel 110, respectively. The dust-proof member 420 may effectively fill a gap between the lens assembly 300 and the see-through plate 410, thereby improving the sealing property of the second cavity.

Referring to FIG. 1, in some embodiments of the present application, the dust shield 420 has a closed loop configuration. Specifically, the dust-proof member 420 is circumferentially disposed along the circumferential direction of the second cavity to completely block the circumferential gap of the second cavity, thereby improving the sealing property of the second cavity.

In some embodiments of the present disclosure, the dust-proof member 420 is made of foam. The foam has good sealing performance and light weight, and can effectively reduce the weight of the whole equipment.

Simultaneously, because different wearers ' interpupillary distance is different, screen 100, support 200 and lens group 300 all need to change along with interpupillary distance's change, and when lens group 300's position changed, the bubble cotton can produce certain deformation to the gap that produces between shutoff lens group 300 and perspective board 410.
