Benefits of technology

The invention is an electromechanical extending device for a movable sofa that has a simple structure, improves installation efficiency, reduces shaking and inconsistent sides, increases safety, and reduces the risk of injury from the motor installation head. The device includes a motor movement sliding block and a motor head connected via a bolt, improving the installation efficiency of the motor. The invention also unifies the structure of the mechanical extending device of the electric rocking chair or swinging chair, reducing controlling cost, and improves the electric function, safety, reliability, efficiency, and level of comfort of the movable sofa.

Problems solved by technology

The current electromechanical extending device of a movable sofa has six major disadvantages: 1, in the electrically driving manner of the movable sofa, the structure is too complicated, influencing the kinetic energy efficiency of the motor; 2, in the electrically driving manner of the movable sofa, the installation position of the motor installation head is too high so that there is a risk of the hip touching the motor installation head when people are seated in the sofa, and there is a serious safety problem; 3, in the electrically driving manner of the movable sofa, the installation is complicated, influencing the installation efficiency of the movable sofa; 4, in the electrically driving manner of the movable sofa, the motor installation tube piece is too complicated so that there is a problem that the sofa cannot be installed in the production process; 5, in the electrically driving manner of the movable sofa, there is a problem of shaking and inconsistent left and right sides in the running process; and 6, the mechanical device of the electric rocking chair or swinging chair of the movable sofa has an inconsistent structure, increasing the manufacturing cost of the movable sofa.
