Abstract

The invention relates to the mechanical field, and relates to a helmet-mounted display provided with a lens translation adjustment mechanism, which comprises a helmet-mounted display body. The helmet-mounted display body is provided with at least one lens translation adjustment mechanism; each lens translation adjustment mechanism comprises a lens frame provided with a lens, and the outer contour of the lens frame has a gear-shaped structure; the front end surface and the rear end surface of the lens are rotary symmetrical surfaces; the lower end of the lens frame is provided with a track for rolling of the lens frame; the track is provided with a first straight rack engaged with the outer contour of the lens frame; the upper end of the lens frame is provided with a driving mechanism for driving the lens frame to roll along the track; the driving mechanism comprises a second straight rack engaged with the outer contour of the lens frame; the second straight rack has a horizontal movement direction; and the helmet-mounted display body is provided with a shell, and the first straight rack is fixedly connected with the shell. Translation adjustment can be carried out on the lens conveniently, and stop at any position can be realized.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a helmet-mounted display. Background technique [0002] Virtual reality is the use of computer simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, allowing users to observe things in the three-dimensional space in a timely and unlimited manner . The virtual reality system is an interactive virtual environment generated by a computer that acts on the user through sight, hearing, and touch to create an immersive feeling. Human-computer interaction in virtual reality goes far beyond the traditional mode of keyboard and mouse. Using digital helmets, digital gloves and other sensor devices, three-dimensional interactive technology, voice recognition, and voice input technology have become important means of human-computer interaction. Among them, the head-mounted display component is the key to realizing the vi...
