Title:
HEAD-MOUNTED ADJUSTING APPARATUS AND HEAD-MOUNTED DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/183727
Kind Code:
A1
Abstract:
A head-mounted adjusting apparatus and a head-mounted display device. The head-mounted adjusting apparatus comprises: a mounting housing (100) provided with a mounting hole (110); two racks arranged in parallel in the mounting housing (100) and slidably connected to the mounting housing (100); a gear (200) meshed between the two racks; a position-limiting wheel (300) coaxially connected to the gear (200); and an annular retainer (400) rotatably provided in the mounting hole (110) and sleeved on the position-limiting wheel (300). The annular retainer (400) is provided with mounting recesses (410) that run through an inner annular surface and an outer annular surface, a rolling piece (420) is rotatably provided in each mounting recess (410), and the width of each rolling piece (420) is greater than that of the corresponding mounting recess (410) in the radial direction of the annular retainer (400). The outer periphery of the position-limiting wheel (300) is provided with position-limiting planes (310), gaps are reserved between the position-limiting wheel (300) and the annular retainer (400), and the position-limiting wheel (300) rotates with respect to the annular retainer (400), such that the position-limiting planes (310) can abut against the rolling pieces (420). Unnecessary noise generated by the head-mounted adjusting apparatus in an adjusting process is avoided, thereby improving use experience of users.
