Electric mechanical extension device for movable sofa

Abstract

The invention relates to an electric mechanical extension device for a movable sofa. The electric mechanical extension device is mainly suitable for movable sofas, particularly electric rocking chairs and swinging chairs. The electric mechanical extension device for the movable sofa comprises a mechanical extension device and an electric device, wherein the electric device consists of a motor, a front motor connecting pipe, a back motor connecting pipe, a motor head mounting piece, a motor motion slide block, a slide block mounting piece, a rotating connecting piece and a rotating bent piece; the front motor connecting pipe is connected with a leg connecting piece; the motor head mounting piece is connected with the front motor connecting pipe, and is rotationally connected with the motor; the motor motion slide block is arranged on a motor slide rail; the sliding mounting piece is fixed on the back motor connecting pipe, and is rotationally connected with the motor motion slide block; the back motor connecting pipe is connected with the rotating bent piece; the rotating bent piece is rotationally connected with an ascending connecting piece; the rotating connecting piece is rotationally connected with the rotating bent piece and a mounting plate. The electric mechanical extension device is simple in structure, safe and reliable for driving, high in efficiency, low in cost and high in comfort.

Description

Technical field [0001] The invention relates to an electromechanical extension device for a movable sofa, in particular to an electromechanical extension device for a multifunctional movable sofa whose legs can be folded or unfolded, and the backrest angle can be adjusted to a certain extent. It is mainly suitable for movable sofas, especially electric rocking chairs , Swing chairs. Background technique [0002] At present, there are six major shortcomings in the existing electromechanical extension device of the movable sofa: 1. The structure of the electric driving method of the movable sofa is too complicated, which affects the kinetic energy efficiency of the motor; 2. The electric driving method of the movable sofa will cause the installation position of the motor mounting head to be excessive. High, leading to the danger of contact between the buttocks and the motor installation head when sitting on the sofa, and there are serious safety problems; 3. The installation of the...

Problems solved by technology

[0002] At present, there are six major deficiencies in the existing electromechanical stretching devices for movable sofas: 1. The structure of the electric driving method of the movable sofa is too complicated, which affects the kinetic energy efficiency of the motor; High, resulting in the risk of contact between the buttocks and the motor installation head when people sit on the sofa, and there are serious safety problems; 3. The installation of the electric drive method of the movable sofa is complicated, which affects the installation efficiency of the movable sofa; 4. The motor installation of the movable sofa electric drive method The pipe fittings are too complicated, which leads to the problem that the sofa cannot be installed normally during the production process

5. There are problems of jitter and inconsistency between left and right in the operation of the electric drive mode of the movable sofa

6. The structure of the movable sofa electric rocking and swinging chair mechanism is inconsistent, which increases the production cost of the movable sofa
