Functional sofa support assembly with pinch protection and extension enhancement

Abstract

The invention relates to a functional sofa support assembly with an anti-pinching protector and an extension enhancing device. The functional sofa support assembly comprises a main support, a backrest assembly, a driving assembly and an extension and retraction assembly. The extension and retraction assembly comprises a drive arm, a driving arm, a large foot plate and a small foot plate. The drive arm is connected with the driving assembly, the large foot plate and the small foot plate. The drive arm comprises a first drive arm body and a second drive arm body. The first drive arm body is provided with an outwards-protruding protective separation blade, the protective separation blade and the first drive arm body are connected to form an integral structure, and the second drive arm body is connected with the large foot plate and the small foot plate at the same time. A first connecting piece is welded and fixed to a front driving rod, and a second connecting piece is welded and fixed to a rear driving rod. The small foot plate is additionally arranged, and the length of a sofa foot rest is increased; the protective separation blade of the first drive arm body and the second drive arm body are kept overlapped all the time in the extension and retraction process of the drive arm, no shearing action is carried out, and potential safety hazards are eliminated. The functional sofa support assembly is more compact in structure, wider in application range, convenient to install and safe and comfortable in use.

Description

technical field [0001] The invention relates to the technical field of sofas, in particular to a functional sofa support assembly provided with anti-pinch protection, a small foot plate and an extension enhancing device. Background technique [0002] Existing electric retractable multifunctional sofas, also known as functional sofas, can be used as ordinary sofas after shrinking, and can be used as sofa beds after stretching. They are easy to control and comfortable to use. With the wide application of electric multifunctional sofas, the safety and stability of electric sofas are more prominent. For example, when a functional sofa stretches under the drive of a motor, a gradually deformed gap will be formed between its two transmission arms, and the gap will perform a shearing action as the transmission arms expand and contract. At this time, if a child puts his hand into the above-mentioned gap, it will cause serious injury to the child. If an animal puts its limbs into t...

Problems solved by technology

But this will not only put forward higher requirements for the later sofa installation, but also increase the cost of product packaging and transportation, and sometimes the stability of the electric sofa will be reduced due to low installation quality

Thereby reducing the comfort of using the sofa, the user experience of the product is not ideal enough
