Dustproof structure used for head-mounted display

Abstract

The invention relates to the field of head-mounted display equipment, and in particular, relates to a dustproof structure used for a head-mounted display. The dustproof structure comprises a display screen, a display screen bracket, a left lens, a right lens, a left lens frame, a right lens frame, a dustproof piece and an eye shield, wherein the display screen is fixed on the display screen bracket; a dustproof groove used for installing the dustproof piece is formed in the display screen bracket; the left lens is installed on the left lens frame, and the right lens is installed on the right lens frame; the left lens frame and the right lens frame are installed on the display screen bracket, and are in contact with the dustproof piece in the dustproof groove; and the eye shield is pressed on the left lens and the right lens, so that the left lens frame and the right lens frame are pressed on the dustproof piece with proper pressure. The dustproof structure provided by the invention makes full use of physical connection relationships among the components through reasonable design, simplifies the space layout, and has the advantages of simple structure and good dustproof effect.

Description

Technical field [0001] The present invention relates to the field of head-mounted display devices, and in particular, to a dust-proof structure for a head-mounted display. Background technique [0002] A head-mounted display is a device that magnifies the image on the ultra-micro display screen through a set of optical systems (mainly precision optical lenses), and projects the image on the retina, thereby presenting the large-screen image in the eyes of the viewer. With the progress and development of science and technology, head-mounted displays have gradually become civilians. The head-mounted displays currently on the market include: head-mounted displays that do not support pupil distance adjustment and head-mounted displays that support pupil distance adjustment. For head-mounted displays that support pupil distance adjustment, the In the limited mechanical design space of such products, it is necessary to design multiple solutions to improve the overall performance of the...

Problems solved by technology

[0003] In the Chinese patent application with the application number 201510204170.6, the dust-proof solution for the head-mounted display adopted is to install the mounting part of the lens bracket on the mounting seat of the display bracket, and then place the ring-shaped soft rubber sleeve on the lens bracket The mounting part and the mounting seat of the display stand, although this solution has a certain dust-proof effect, but limited by the size of the mounting seat, the sliding range of the lens support is limited, resulting in a small adjustment range of the pupil distance. And by manually pushing the lens holders to adjust the interpupillary distance, it is impossible to accurately adjust the distance between the two lens holders, which affects the user experience of the user; in addition, this solution has the disadvantages of complex structure and high manufacturing cost.
