Description

Technical Field

[0001] The utility model relates to the technical field of night vision devices, in particular to a head-mounted binocular night vision device. Background Art

[0002] Night vision goggles are nighttime external sights with image intensifiers as their core components. When working, they do not use infrared searchlights to illuminate the target, but use the light reflected by the target under weak light to be enhanced by the image intensifier on the fluorescent screen into a visible image that can be perceived by the human eye to observe and aim at the target. Infrared night vision goggles are military night vision instruments that use photoelectric conversion technology. They are divided into active and passive types: the former uses an infrared searchlight to illuminate the target and receives reflected infrared radiation to form an image; the latter does not emit infrared rays, but relies on the target's own infrared radiation to form a "thermal image."

[0003] Most of the existing head-mounted binocular night vision goggles are fixedly installed, which makes it inconvenient for operators to move the night vision goggles up and down according to their own needs, reducing the comfort of viewing in later use. In addition, the lens of most night vision goggles is directly exposed to the outside world. Collisions when not in use later will cause scratches on the lens, affecting the viewing comfort.
