The invention relates to the mechanical field, and relates to a helmet-mounted display provided with a mobile mechanism with a screen support capable of moving back and forth, which comprises a helmet-mounted display body. The helmet-mounted display body comprises a shell; the shell is internally provided with a mobile mechanism; the mobile mechanism comprises a screen support provided with a display screen; the screen support is provided with a round gear; the shell is also internally provided with a driving mechanism driving the round gear to roll; the driving mechanism comprises a first straight rack; the first straight rack is in sliding connection with a first sliding rail, the first straight rack is in engaged connection with the round gear, and the guiding direction of the first sliding rail is the back-forth direction; the shell is also internally provided with a second tack for rolling of the round gear, the second track is provided with a second straight rack, and the second straight rack is in engaged connection with the round gear; and the guiding direction of the first sliding rail and the guiding direction of the second track are parallel. The traditional fixed screen support is improved into a mobile screen support, and the display screen can move back and forth.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a virtual reality helmet. 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 helmet display component is the key to realizing the virtual ...
