The invention, which relates to the technical field of the night-vision device, discloses a rotation and
rollover automatic power-on and power-off structure of a night-vision device, comprising a mirror bracket, two rotating arms, two
night vision goggles, two magnets and two Hall sensors. The structure realizes automatic power-on of the
night vision goggles in use and automatic power-off of the
night vision goggles in non-use through a non-rigid
contact mode by utilizing the interaction of the
magnet and the Hall sensor. Specifically, when the rotating arm drives the night vision goggles to rotate to a certain angle, the
magnet enters the sensing range of the Hall sensor, and a trigger
signal enables the night vision goggles to be powered on; on the contrary, when the rotating arm drives the night vision goggles to rotate and leave the induction range, the night vision goggles are automatically powered off. In addition, the rotating shaft between the rotating arm and the mirror bracket can adjust the damping, and the contact part is provided with a sealing ring, so that the dustproof and waterproof performance of the structure is ensured, and the structure is suitable for various working environments.
