AI Technical Summary
Existing forestry survey planning remote sensing drones are prone to vibration during landing, which can affect the balance of the drone and potentially damage internal components. Existing shock absorption methods also affect the balance of the drone and are not stable enough.
The system employs a combination of a first and second buffer assembly, a rebound locking assembly, and an adjustment assembly. Through the combined use of a multi-layered buffer structure and springs, it absorbs the impact force during landing and locks the spring rebound at the critical point to ensure a stable landing of the drone.
It effectively absorbs and weakens the impact force during landing, improves the stability of drone landing, protects internal components, and adapts to the cushioning needs of drones of different weights.
