Abstract: The invention discloses a head-mounted display apparatus. The head-mounted display comprises a headband module and a head-mounted display module, wherein the head-mounted display comprises an optical module, the headband comprises a connecting structure connected with the head-mounted display housing so as to adjust the wearing angle of the head-mounted display module; The optical module comprises a module housing, a left lens barrel mechanism, a right lens barrel mechanism, a left sight distance adjusting mechanism and a left pupillary distance adjusting mechanism for adjusting the sight distance and pupillary distance of the left lens barrel mechanism, a right sight distance adjusting mechanism and a right pupillary distance adjusting mechanism for adjusting the sight distance and pupillary distance of the right lens barrel mechanism. The head-mounted display can separately adjust the sight distance and pupillary distance of the left and right lens barrel mechanism, as well as the wearing angle.

Abstract: The invention discloses an optical module and a head-mounted display apparatus. The optical module includes a left/right lens barrel mechanism, a left/right sight distance adjusting mechanism, and a left/right pupillary distance adjusting mechanism; The left lens barrel mechanism includes a left lens barrel assembly and a left display screen disposed behind the left lens barrel assembly through a left screen bracket; The left sight distance adjusting mechanism adjusts the distance between the left display screen and the left lens barrel assembly; The left pupillary distance adjusting mechanism drives the left lens barrel mechanism to move left and right. Symmetrically, the structure of the right side is the same as left. The optical module adjusts the sight distance/pupillary distance of left and right eye separately by the left and right sight distance adjusting mechanism/pupillary distance adjusting mechanism, so that images seen by both eyes are clearer.
