Driving device applied to automatic rocking chair

Abstract

The invention discloses a driving device applied to an automatic rocking chair. The driving device comprises a hollow shell, wherein the inner part of the shell is provided with an electric magnet; the lower part of an iron core of the electric magnet is connected with an ejector rod which can stretch out of the shell or shrink into the shell; an opening which is used for enabling the ejector rod to get in and out is formed in the side wall of the shell. According to the driving device applied to the automatic rocking chair, disclosed by the invention, because the ejector rod is driven to stretch out of the shell and lean against a supporting surface through adopting the electric magnet, a rocking chair main body is further driven to swing; the ejector rod can repeatedly get in and out of the shell and lean against the supporting surface when the electric magnet is repeatedly and intermittently energized, so that the rocking chair main body is enabled to be able to further repeatedly swing, and the purpose of enabling the rocking chair to automatically swing is realized; by adopting the structure, the structure of the driving device is facilitated to be simplified, production and processing are convenient, and the production cost of the rocking chair is reduced.
