AI Technical Summary

Technical Problem

The existing mid-section folding structure of drone arms has problems such as cumbersome locking methods, locking gaps causing swaying that affects flight stability, and insufficient locking force.

Method used

The arm quick-folding mechanism employs multiple locking mechanisms. Through the rotational connection of the first and second folding components, combined with the synergistic effect of the first and second locking components, it achieves automatic locking and circumferential limiting, providing progressive locking force and radial preload, thus avoiding additional manual operation.

Benefits of technology

It simplifies the folding and unfolding operation of the arms, improves flight stability and locking reliability, reduces arm sway, and enhances the stability and reliability of locking performance.
