AI Technical Summary
Existing helicopter landing gear cannot effectively reduce vibrations during landing, causing vibrations to be transmitted to the internal parts of the aircraft and damage electronic components.
It adopts a movable frame, movable rod, sleeve and magnetic ring shock absorption mechanism, and utilizes the principle of magnetic pole repulsion and spring buffer, combined with the height adjustment mechanism to adjust the height through bolts.
It effectively reduces vibration transmission during landing, protects internal electronic components, and allows for adjustable landing gear height to adapt to different conditions.
