AI Technical Summary
The AR glasses in existing holographic brain-computer interface helmets lack effective fixation when raised, resulting in loosening and wear of the pivot structure, which poses a safety hazard.
A protective structure was designed, comprising an L-shaped plate, a base plate, and a clamping plate, forming a U-shaped support structure. The L-shaped plate and the base plate support the AR glasses, preventing them from relying solely on the weight of the rotating bearing, and springs and limiting rods ensure stable support.
This effectively prevents AR glasses from loosening or being damaged due to the weight of the rotating bearing when raised, improving safety and stability and avoiding the risk of glasses shaking or falling off.
