AI Technical Summary
When a drone lands, the bottom of the camera is easily damaged by protrusions on the ground, and existing technology lacks effective protective measures.
The system employs a protective plate and ring structure. The rotation direction of the protective plate is limited by a limiting plate to prevent damage to the camera and rotor. The protective plate is automatically adjusted by an electric telescopic rod and a sliding wheel, and reset by the sliding wheel and a torsion spring.
It effectively protects the drone's bottom and camera from damage caused by ground protrusions, while simplifying the rotor maintenance process.
