Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0017] The electric mechanical extension device of the movable sofa in this embodiment includes the mechanical extension device of the prior art (for example, the patent document with the patent number 200920200532.4, the patent publication document with the publication number 102657449A, the patent document with the patent number 201220668439.8), and its structural characteristics are electric The device is composed of a motor 7, a motor drive assembly, a motor head fixture 8, and an electric connecting rod 9. The motor 7 adopts a rail motor, and the motor drive assembly is a fixed overall structure (there is no relative movement inside). The motor head is rotationally connected with the motor head fixing part 8 fixed on the electric connecting rod 9 through the second rotating shaft 4 (the other end of the motor 7 and the motor guide rail is not connected...

Abstract

The invention relates to an electromechanical stretching device for a movable sofa, which includes a mechanical stretching device and an electric device. The electric device is composed of a motor, a motor drive assembly, a motor head fixing part, and an electric connecting rod. The motor head fixing part fixed on the electric connecting rod is rotatably connected, and the motor drive assembly is rotatably connected to the mechanical stretching device through the first rotating shaft. The motor drive assembly is composed of a motor slider fixing bracket, a transmission connector, a fixing bracket connector, and a motor moving slider. The motor slider fixing bracket is fixed on the motor moving slider, and the fixing bracket connector is connected with the motor slider fixing bracket. The motor slider fixing bracket is fixedly connected with the transmission connector, and the transmission connector is rotationally connected with the leg rest of the mechanical stretching device through the first rotating shaft. The invention changes the original electric drive mode device, which is beneficial to improving the electric installation and operation efficiency of the movable sofa, and improves the degree of automation and comfort of the sofa.

Description

technical field [0001] The invention relates to an electromechanical stretching device for a movable sofa, in particular to a multifunctional electromechanical stretching device for a movable sofa with foldable or unfoldable legs and adjustable backrest angle. Background technique [0002] At present, there are four major deficiencies in the existing electromechanical stretching devices for movable sofas: 1. On the market, the structure of the electric driving method of movable sofas is too complicated, which affects the kinetic energy efficiency of the motor; 2. On the market, the electric driving method of movable sofas will appear Shaking phenomenon affects the comfort of the movable sofa; 3. On the market, the installation of the electric drive method of the movable sofa is complicated, which affects the installation efficiency of the movable sofa; 4. On the market, the motor head of the movable sofa electric drive protrudes from the electric connecting rod, and the legs ...
