AI Technical Summary
Existing baby crib rocking mechanisms generate significant impact forces during start-up and stop, have low transmission precision, and cannot accurately control the transmission ratio and speed. This results in uneven rocking amplitude and unstable speed, affecting the rocking effect of the baby crib and posing safety hazards.
The crib employs a drive gear and driven gear meshing structure, combined with a sliding groove and limit rod design. The drive motor drives the meshing motion of the rack and driven gear to achieve high-precision linear motion positioning of the crib, while the limit rod and arc-shaped guide groove ensure the controllability and stability of the swaying.
It improves the accuracy and stability of the crib's rocking motion, ensuring the crib's safety and comfort during the rocking process, avoiding shaking and deviation, and providing a stable sleep environment.
