Abstract

The invention discloses a head-mounted adjustment device and a head-mounted display device, wherein the head-mounted adjustment device includes: a mounting shell; two racks are arranged in parallel with the mounting shell and are slidably connected with the mounting shell; gears, Engaged between the two racks, and a limit shaft is protruded on one side; the limit ring is sleeved outside the limit shaft, and the outer peripheral edge of the limit shaft and the inner peripheral edge of the limit ring form a limit ring groove; the ring The cage is provided with a receiving groove, and the limit roller is rotatably arranged in the containing groove, and the ring cage is rotatably arranged in the limit ring groove; and a locking switch is used to make the ring cage and the limit ring relatively Rotate, so that the limit roller reaches the locking position or the free position; at the locking position, the limit roller abuts against the limit ring and the limit shaft at the same time; at the free position, the limit roller and the limit ring or There is a gap between the limit shafts. The technical solution of the present invention aims to prevent unnecessary noise from the head-mounted adjustment device during the adjustment process, so as to improve the user experience.

Description

technical field [0001] The invention relates to the field of head-mounted devices, in particular to a head-mounted adjustment device and a head-mounted display device. Background technique [0002] Head-mounted display devices such as virtual reality head-mounted devices, augmented reality head-mounted devices, and mixed reality head-mounted devices generally include a host for displaying image information to a user and a wearing part for wearing the host on the user's head. [0003] The wearing part usually includes straps or side arms extending from both ends of the host to one side, the head-mounted display device is worn behind the user's head, and the straps or side arms are located on both sides of the user's head. In view of the different head circumferences of different users, in order to adapt to wearing by different users, the wearing part usually also includes an adjusting part for adjusting the strap or the length of the side arm to adjust the wearing tightness o...
