Electric Sofa Gear Motor

Intelligent technology has become the future of smart homes. In following with this trend, the ZHAOWEI linear drive system has been developed to be utilized on intelligent sofa transmission.

The ZHAOWEI sofa gear motor push-rod drive system uses a DC motor to drive the screw, fulfilling the smart expansion and contraction of the sofa footrest device. The telescopic rod at the sofa footrest can extend, but is unable to rotate. The ZHAOWEI gear motor has positive and negative poles; the positive pole stretches out, and the negative pole retracts. By switching the positive and negative poles of the DC motor, the motor in the smart electric sofa will rotate in a clockwise or counter-clockwise direction to retracting and unfold.

Based on the traditional sofa design, the intelligent electric sofa gearbox drive system collects data through embedded technology, RFID and other IoT sensors, and then transmits the collected data to the controller for processing. The controller then passes through various sensors after processing. This facilitates the fulfillment of the entire terminal, achieving a variety of specific functions, and systematically works with other indoor appliances, resulting in a comfortable experience.


In order to achieve reliability in the telescopic retracting and unfolding of the smart electric sofa, ZHAOWEI has utilized a planetary gearbox to achieve a compact size, and high torque. There are 2-stage, 3-stage and 4-stage transmission options that the reduction ratio can be adjusted to, and the input speed, as well as torque of the gearbox, can be adjusted according to the design requirements of the starting motor of the electric sofa. After the information is transmitted, corresponding feedback is made once the correct information is checked. Different commands can be sent to the circuit board that accepts information via Bluetooth, which starts the motor. The motor is combined with the ZHAOWEI smart electric sofa gearbox to achieve intelligent telescopic expansion.


ZHAOWEI Drive aims to enhance home life. Regardless of the kind of sofa, the first thing that comes to mind is its comfort and ease. The circuit and current direction can be controlled by an App on a mobile device, or the function buttons on the sofa armrests. This allows the sofa angle to be intelligently set for sitting or lying back, and retains the memory for the sofa setting. It then automatically returns to its normal angle after the person gets up. When the person returns to sit or lie down, it automatically adjusts to the angle set before. A smarter sofa can also remember each person’s preferred sitting posture according to each of their bodies and weights, and intelligently identifies the member who is sitting, and provides them a comfortable angle.
