Dual-drive mechanical stretching device

Abstract

The invention relates to a dual-drive mechanical stretching device which comprises two stretching mechanisms, a driving assembly A, a driving assembly B and a base, wherein the two stretching mechanisms are arranged on the left and right sides of the base; each stretching mechanism comprises a backrest assembly, a support assembly and a bracket assembly; the lower ends of the support assemblies are hinged to the base; the backrest assemblies are hinged to the rear ends of the support assemblies; the bracket assemblies are hinged to the front ends of the support assemblies; the driving assembly A comprises a driving connecting rod A which is connected with the rear ends of the two bracket assemblies, a flexible power mechanism A and a driving connecting rod C which is connected with the rear ends of the two support assemblies; two ends of the flexible power mechanism A are respectively hinged to the driving connecting rod A and the driving connecting rod C; the driving assembly B comprises a driving connecting rod B which is connected with the front ends of the two support assemblies and a flexible power mechanism B; the two ends of the flexible power mechanism B are respectively hinged to the driving connecting rod B and the rear end of the base. The two independent driving assemblies are respectively arranged to control the bracket assemblies and the support assemblies, so that the comfort level is high and the adjusting range is broad.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a double-drive mechanical stretching device. Background technique [0002] With the continuous improvement of living standards, people's requirements for a comfortable life are getting higher and higher. In a fast-paced, high-stress life, being able to have a comfortable sofa or lounge chair for rest can play a very good role in improving people's living standards. The electric sofas or electric leisure chairs currently on the market can be driven by motors to realize the stretching and folding of the footrests of the sofa or leisure chairs and the adjustment of the angle of the backrest. [0003] However, most electric sofas or electric leisure chairs on the market are driven by a single motor. In the process of adjusting the footrest and backrest of the sofa, they can only be adjusted at the same time or backwards, and the footrest and backrest cannot be adjusted separately....
