Abstract

The invention relates to an electric rocking chair frame. The electric rocking chair frame comprises a pedestal, a seat cushion support, a backrest support and a driving mechanism, wherein the backrest support is hinged on the back part of the seat cushion support; the angle of the backrest support can be regulated relative to the seat cushion support; the electric rocking chair frame is characterized in that: the back part of the seat cushion support is hinged on the pedestal through end parts of support rods on the two sides; the driving mechanism is fixed on the middle front part of the pedestal and is connected with the middle front part of the seat cushion support through a connecting rod; the driving mechanism comprises a motor, a worm gear case and an eccentric wheel; the motor is installed on a shell of the worm gear case; motor output is in transmission connection with a worm through a belt; the eccentric wheel is fixed on a worm gear shaft; a movable sleeve is sleeved outside the eccentric wheel; and the movable sleeve is fixed with one end of the connecting rod. A primary motor output of the driving mechanism adopts belt transmission, and when the backrest support collides with an obstacle, the belt slips in order to protect the motor; and a secondary motor output adopts worm gear worm reduction and has a self-locking function, and when the motor is powered off, the rocking chair can keep the angle and does not swing freely.

Description

Technical field: [0001] The invention relates to an electric rocking chair bracket, in particular to an electric rocking chair which can electrically adjust the inclination angle of a backrest to provide a comfortable angle for sitting or lying down, and can also electrically swing at a specific angle.
