Problems solved by technology

[0003] Since the interpupillary distance of users of different ages is different, the head-mounted device needs to be able to adjust the distance between the two lens barrels to improve the comfort of use. The interpupillary distance adjustment mechanism of conventional head-mounted display devices is generally in the form of a paddle. There is a shrapnel limit inside. When adjusting, the strength is not well grasped, and it is easy to dial it or get stuck in the middle of several gears and not adjust it in place.

Abstract

The invention discloses a head-mounted display device, which belongs to the technical field of head-mounted displays. There is a threaded column arranged vertically. A sleeve is set on the outside of the threaded column. The sleeve is provided with an internal thread matching the threaded column. The bottom end of the sleeve is provided with a rotating gear. A second button is arranged between the button and the threaded column. a spring; the two lens barrels are respectively connected with horizontal connecting rods, and the two connecting rods are provided with rotating racks that can mesh with the two rotating gears, and the rotating racks of the two connecting rods are respectively engaged on opposite sides of the rotating gears; The casing is provided with a travel limit structure for limiting the moving distance of the lens barrel each time. The two lens barrels are respectively connected with the travel limit structure. The travel limit structure allows the lens barrel to move only one gear at a time, thus solving When the gear is adjusted, the gear is over-shifted and the gear is not adjusted in place.

Description

technical field [0001] The invention belongs to the technical field of head-mounted displays, and in particular relates to a head-mounted display device. Background technique [0002] With the development of electronic products, more and more head-mounted display devices such as virtual reality head-mounted devices, augmented reality head-mounted devices, and mixed reality head-mounted devices have appeared in real life. [0003] Since the interpupillary distance of users of different ages is different, the head-mounted device needs to be able to adjust the distance between the two lens barrels to improve the comfort of use. The interpupillary distance adjustment mechanism of conventional head-mounted display devices is generally in the form of a paddle. There is a shrapnel limiter inside, if you don’t grasp the force well when adjusting, it is easy to dial it or get stuck in the middle of several gears and not adjust it in place. Contents of the invention [0004] The te...
