Electric sofas are driven by a built-in motor. After gear reduction, the motor drives a lead screw or push rod, converting the motor's rotational motion into linear motion, thus controlling the height adjustment of components such as the sofa backrest. Users can control the sofa via buttons on the armrests, a remote control, or smart devices. Its core components mainly include the drive motor, reduction gears, lead screw, nut, push rod, slide, and control switches.
Traditional electric sofas have long faced the technical bottleneck of not being able to simultaneously achieve "zero gravity, zero wall contact, and true high legs." Some electric sofas, through the use of a double-slide structure and a specific curve design, have achieved compatibility between zero gravity, zero wall contact, and true high legs. When zero-gravity mode is activated, the sofa can be adjusted to an angle where the seat cushion tilts upwards by 20 degrees, the thigh-to-calf angle is 160 degrees, and the waist-to-thigh angle is 135 degrees, so that the knees are slightly higher than the heart. At the same time, the 14cm true high leg design allows robotic vacuum cleaners to freely enter and exit.
