Abstract

The invention discloses a headrest, leg support and backrest angle adjuster of electric sofa. The angle adjuster comprises a synchronous transmission shaft, a driving motor for driving the synchronoustransmission shaft to rotate and planetary gear mechanisms connected to two ends of the synchronous transmission shaft; the planetary gear mechanisms are simple in internal structure, capable of achieving 360-degree rotation, suitable for different occasions and good in universality, the manufacturing cost is reduced, the adjusting mechanism connected with the planetary gear mechanisms is drivenby a connected driven rod, and good operation stability, durability and low noise are achieved.

Description

technical field [0001] The invention belongs to the technical field of home sofas, and relates to an electric sofa headrest, a leg rest, and a backrest angle adjuster. Background technique [0002] With the improvement of people's living standards, there are more and more requirements for the angle adjustment function of home seats. However, the transmission home sofa only provides a fixed posture for people, and the seat shape cannot be adjusted. In order to pursue the comfort of the sofa, the high-end sofa has an adjustment function. The screw drives the multi-link mechanism to realize the adjustment function; however, the mechanism has too many riveting processes, the manufacturing cost is high, and there will be abnormal noise and shaking after working for a period of time. Contents of the invention [0003] In view of the above problems, the present invention proposes an electric sofa headrest, leg rest, and backrest angle adjuster, which well solve the problems of m...
