Problems solved by technology

Since the electric cylinder is generally located in the middle of the functional iron frame, but it cannot be completely in the middle during installation, so when the iron frame of the sofa is subjected to driving force to change its posture, the force on both sides of the seat frame is inconsistent, and it is prone to twisting and poor stability.

Embodiment 1

[0045] The embodiment of the present application discloses a functional sofa mechanical stretching device with a stabilizing mechanism. refer to image 3 , a functional sofa mechanical stretching device with a stabilizing mechanism includes an armrest mounting plate 1 , a seat frame 2 , a backrest 3 , a leg support 4 , a connecting assembly 5 and a driving member 7 . Two armrest mounting plates 1 are provided and are respectively located on both sides of the seat frame 2. A reinforcing rod 6 is arranged between the armrest mounting plates 1, and two ends of the reinforcing rod 6 are fixedly connected to the two armrest mounting plates 1 respectively. The backrest 3 is rotatably connected to the armrest mounting plate 1 , and the seat frame 2 is oscillatingly connected to the armrest mounting plate 1 through the connecting assembly 5 . There are two connecting components 5 located on both sides of the seat frame 2 respectively. The leg support part 4 is rotatably connected to...

Embodiment 2

[0060] The difference between embodiment 2 and embodiment 1 is that, referring to Figure 9 and Figure 10 , both ends of the stabilizing link 33 are respectively fixedly connected to the suspension front support member 13 . When the sofa changes from a sitting position to a lying position, the stabilizing link 33 rotates backwards following the swing of the suspension front support 13, and the distance from the seat surface of the seat frame 2 becomes larger, the torque becomes larger, and the stability is better . The probability of twisting of the seat frame 2 during use is reduced.

[0061] Specifically, the suspension front support 13 includes a vertical rod portion 34 connected to the armrest mounting plate 1 and a horizontal rod portion 35 fixedly connected to the lower end of the vertical rod portion 34 . Both ends of the stabilizing link 33 are respectively fixedly connected to the cross bar portion 35 .

Abstract

The invention relates to a functional sofa mechanical stretching device with a stabilizing mechanism, which comprises an armrest mounting plate, a seat frame and two connecting assemblies connected to the two sides of the seat frame respectively, and each connecting assembly comprises a front seat frame supporting connecting rod, a rear seat frame supporting connecting rod, a forward moving connecting piece and a suspension swing assembly, the front seat frame supporting connecting rod and the rear seat frame supporting connecting rod are both rotationally connected to the seat frame, the two ends of the forward moving connecting piece are rotationally connected to the front seat frame supporting connecting rod and the rear seat frame supporting connecting rod respectively, the forward moving connecting piece is connected to the armrest mounting plate through the suspension swing assemblies, and a stable connecting rod is connected between the two suspension swing assemblies. The stabilizing connecting rod is connected to the suspension swing assembly. When the sofa is changed from a sitting posture to a lying posture, the stable connecting rod moves along with the movement of the suspension swing assembly, and the torque is increased, so that the stability of the seat frame is better, and the seat frame is not easy to twist.

Description

technical field [0001] The present application relates to the field of home furnishing, in particular to a functional sofa mechanical stretching device with a stabilizing mechanism. Background technique [0002] Functional sofa refers to a sofa with multiple functions, and the sofa can be converted in three states: sitting position, TV position and lying position. [0003] The existing functional iron frame of the sofa provides driving force through an electric cylinder to change the posture. Since the electric cylinder is generally located in the middle of the functional iron frame, it cannot be completely in the middle during installation. Therefore, when the sofa iron frame is subjected to driving force to change its posture, the force on both sides of the seat frame is inconsistent, and it is prone to twisting and poor stability. Contents of the invention [0004] In order to improve the stability of the sofa, [0005] The application provides a functional sofa mecha...
