The electric rocking chair device adopts the non-automatic mechanical rocking device for the movable sofa, although the function of sofa movement can be realized, after the rocking chair stops rocking, a user needs to want to apply a force to the electric sofa to start rocking, which is very inconvenient for the user and has very poor use experience.

Chinese patent application No. CN202011238079.3 discloses an electric rocking device of a sofa rocking chair, which comprises a base for providing mounting positions for a sofa rocking adjusting component, a leg extension adjusting component, a backrest adjusting component, a sofa mounting component and an electric component; the sofa swinging adjusting component is arranged on the base and used for adjusting the sofa to swing through swinging; the leg extension adjusting component is arranged on the sofa mounting component and used for adjusting the swing of the front leg placing plate of the sofa through extension and retraction; the backrest adjusting component is arranged on the sofa mounting component and used for adjusting the inclination angle of the sofa backrest through rotation; the sofa mounting component provides a mounting position for the sofa. Above-mentioned patent product sways through electric putter direct action at in-service use in-process, leads to swaying and pause to frustrate and feel very serious, and the comfort level descends.

In order to achieve the effect of electric rocking and to improve comfort at the same time, we propose a rocking sofa power device.
