Description

Optical module adapting device applied to head-mounted display equipment Technical Field The embodiment of the disclosure relates to the field of optical modules and head-mounted display devices, in particular to an optical module adapting device applied to a head-mounted display device. Background In a head-mounted display device (such as smart glasses, a head-mounted display terminal, etc.) of a PWG (Pancake Window Grating, folded optical path grating scheme), such as a scene where a plurality of people at home share the head-mounted display device, the head-mounted display device has been gradually used by the masses along with the development of technology. However, the detachable lens that traditional head-mounted display device set up has the installation loaded down with trivial details, and easy not hard up problem and dismantlement many times can damage ray apparatus equipment, under the circumstances of many people sharing in face family, can not satisfy different degrees user's demand, can not convenient adjustment lens number of degrees, consequently, need one kind can ensure the position and the stability after myopia lens and optical module are installed after the quick assembly disassembly of lens installation to do not damage optical module adapter device of ray apparatus equipment in the dismouting repeatedly. At present, the traditional optical module adapting device mostly depends on using screw and buckle structure, has the problems of complicated installation, easy looseness and the like. However, in practice, it has been found that when using conventional optical module adapting devices, the following technical problems often exist: because the traditional detachable lens depends on the mechanical fixing structure of the screws and the buckles, the disassembly and assembly process is complicated and time-consuming, the efficiency is low when a user changes the lens, and the waiting time is too long when a plurality of people share equipment; because the lens in the traditional technology is required to be disassembled and assembled directly to the optical area or the surface of the shell of the optical machine equipment, and the fixed structure has no protection design, the optical machine equipment is scratched by the lens edge or the tool during repeated disassembly and assembly, so that the optical machine equipment is damaged, the optical performance is attenuated, and the service life of the equipment is shortened.
