Abstract

The invention discloses a transmission mechanism, a head mounted display, and a refraction adjusting method for a head mounted display. The transmission mechanism is used for controlling movement of a first framework relative to a second framework. The first framework is connected to the second framework through a connecting member arranged on the first framework. The transmission mechanism includes a dial wheel, a worm, a turning gear, a transmission shaft and transmission gears. A horizontal frame of the second framework is equipped with a containing groove, part of the dial wheel is arranged in the containing groove and the dial wheel is arranged on the horizontal frame of the second framework with the worm being an axis. The transmission shaft is arranged on the horizontal frame of the second framework. The turning gear sleeves the transmission shaft and fits the worm. The transmission gears are symmetrically arranged on vertical frames of the second framework. The upper portion of the connecting member is equipped with tooth bars, and the tooth bars engage with the transmission gears. When the transmission gears fit the tooth bars, the connecting member drives the first framework to move in a straight reciprocating manner relative to the second framework. According to the technical solution, turning transmission and rotary to rectilinear motion are achieved, transmission is steady and reliable, and the transmission mechanism is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of head-mounted displays, in particular to a transmission mechanism, a head-mounted display and a refraction adjustment method thereof. Background technique [0002] Currently, the head-mounted displays on the market are not well-designed, have complex mechanisms, and are bulky. Moreover, head-mounted displays usually do not consider the needs of users with eye vision defects (such as nearsightedness or hyperopia). Even if some head-mounted displays can achieve diopter adjustment, the refraction adjustment mechanism is particularly complicated and the cost is very high. In addition, the existing Some head-mounted displays often do not have a self-locking function when implementing diopter adjustment, or require additional facilities to assist in realizing self-locking, which will also increase the cost of the diopter adjustment solution and severely limit the development of head-mounted displays.
