AI Technical Summary

Technical Problem

The central column of the existing rotating rocking chair swings due to the difference in passenger weight, causing relative displacement between the drive mechanism and the central column. The coupling bears additional torsional and shear forces, which can easily lead to fatigue damage of elastic elements after long-term use, resulting in problems such as bending of the motor rotor shaft and short circuit of the stator winding.

Method used

A rubber limiting component and a detachable fixing ring component are installed on the inner wall of the upper end of the support cylinder. The mounting plate at the lower end of the central column is inserted into the mounting groove and fixed to the support plate. The drive mechanism is fixed to the mounting plate and moves synchronously to avoid relative displacement and additional stress. At the same time, a lifting mechanism is provided to facilitate the replacement of the rubber limiting component.

Benefits of technology

It effectively protects the drive mechanism, avoids additional torsional and shear forces caused by the shaking of the central column, extends the service life of the coupling, reduces the risk of motor damage, and facilitates the replacement of the rubber limit components.

Abstract

This utility model discloses a main support arm for a rotating rocking chair, including a base with a central column on the base and a drive mechanism for driving the central column to rotate on the base. The utility model provides a rubber limiting component on the inner wall of the upper end of the support cylinder. A mounting plate at the lower end of the central column is inserted into its mounting groove and fixed to the support plate. The drive mechanism is also fixed to the mounting plate. This ensures that the drive mechanism moves synchronously when the central column shakes, avoiding relative displacement and additional torsional and shear forces, effectively protecting the drive mechanism. Simultaneously, a detachable fixing ring assembly is provided at the upper end of the support cylinder to fix the rubber limiting component, and a lifting mechanism is provided at the lower end for easy replacement of the rubber limiting component.
