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 electric and mechanical stretching device of a movable sofa, which comprises a mechanical stretching device and an electric device, wherein the electric device consists of a motor, a motor-driven assembly, a motor head fixing piece and an electric connecting rod; the motor-driven assembly is in a fixed overall structure; a motor head is rotationally connected with the motor head fixing piece fixed on the electric connecting rod; the motor-driven assembly is rotationally connected with the mechanical stretching device by a first rotating shaft, and consists of a motor slide block fixing support, a transmission connecting piece, a fixing support connecting piece and a motor motion slide block; the motor slide block fixing support is fixed on the motor motion slide block; the fixing support connecting piece is connected with the motor slide block fixing support; the motor slide block fixing support is fixedly connected with the transmission connecting piece; the transmission connecting piece is rotationally connected with a leg laying drive of the mechanical stretching device by the first rotating shaft. The stretching device changes the original motor-driven device, so that electric mounting and operating efficiency of the movable sofa can be improved, and the automation degree and the comfort of the sofa are raised and improved.

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 ...
