Description

Technical Field

[0001] The utility model relates to the technical field of rocking chairs, in particular to a rocking structure and a baby rocking chair comprising the same. Background Art

[0002] Baby rockers, a common baby product, are popular with parents because they simulate the rocking effect of a cradle, helping babies fall asleep quickly and enjoy a comfortable environment. Traditional baby rockers mostly use mechanical or inertial rocking mechanisms. Mechanical rocking mechanisms typically include multiple complex connecting rods and gears, resulting in complex structures that are difficult to assemble and maintain. Furthermore, these complex structures are prone to wear and loosening over long periods of use, affecting the smoothness and safety of the rocking. Inertial rocking mechanisms, on the other hand, rely on the rapid start and stop of the motor or changes in rotation direction to generate inertial force, which in turn propels the baby seat back and forth. While this design can achieve the rocking function, the frequent start and stop and rotation direction changes of the motor increase wear and shorten its service life. The generated inertial force can also cause discomfort to the baby. Utility Model Content
