Specifically, as shown in fig. 1, the AR module further includes an AR optical component, the housing 100 includes an AR optical structure mounting shell 110 and a cover 120, the AR optical structure mounting shell 110 is used for mounting the AR optical component, a mounting cavity is formed in the AR optical structure housing 100, and the mounting cavity has an opening; the display module 200 is installed in the installation cavity; the cover 120 is detachably mounted to the opening of the mounting cavity. Further, lid 120 can be dismantled with AR optical structure installation shell 110 and be connected, then the user of being convenient for or workman installs display module assembly 200 in AR optical structure installation shell 110's installation cavity to establish the opening of installation cavity through lid 120 lid, then have better protection and dustproof effect to AR optical assembly and display module assembly 200. The cover 120 may be fixedly attached to the AR optical structure mounting case 110 by screws. Of course, the cover 120 may also be connected to the AR optical structure mounting case 110 by means of a snap connection. In order to ensure better sealing performance at the joint of the cover 120 and the AR optical structure mounting case 110, it is preferable that the cover 120 and the AR optical structure mounting case 110 are screwed. One of the cover 120 and the AR optical structure mounting case 110 may be provided with a screw hole, and the other may be provided with a screw post, and the screw passes through the screw hole and is screwed to the screw post, so as to achieve the effect of screw connection between the cover 120 and the AR optical structure mounting case 110. Further, a foam 900 may be interposed between the cover 120 and the AR optical structure mounting housing 110, so as to further improve the sealing property between the surfaces of the cover 120 and the AR optical structure mounting housing 110, and prevent dust or other impurities from entering the AR optical structure mounting housing 110.
