Multifunctional leisure chair frame structure and control method thereof

Abstract

The invention discloses a multifunctional leisure chair frame structure and a control method thereof. The multifunctional leisure chair frame structure comprises a back frame, a seat frame, a foot rest, a chair leg assembly and a bottom supporting seat fixedly connected to the chair leg assembly. The foot rest is in running fit with the seat frame, and a first link rod mechanism is arranged amongthe front end of the seat frame, the foot rest and the bottom supporting seat; a second link rod mechanism is arranged between the rear end of the seat frame and the back frame; a first telescopic device for controlling the first link rod mechanism is arranged between the seat frame and the bottom supporting seat, a second telescopic device for controlling the second link rod mechanism is arrangedbetween the back frame and the seat frame, and the first telescopic device and the second telescopic device are independently controlled; the first telescopic device acts to enable the front end of the seat frame to upwarp and integrally move backwards, and meanwhile, the foot rest is forwards overturned and unfolded around the seat frame; the second telescopic device acts to enable the back frame to incline backwards relative to the seat frame and integrally move forwards; by controlling the first telescopic device and the second telescopic device to stretch out and draw back, the leisure chair can be stably changed from the sitting posture to the leisure posture to the lying posture.

Description

technical field [0001] The invention relates to the field of seats, in particular to a frame structure and control method of a multifunctional leisure chair. Background technique [0002] The market for leisure chairs has developed rapidly in recent years, and leisure chairs have gradually entered many people's offices, living rooms, and bedrooms. From the earliest leisure chair with the most simple technology, to the new type of leisure chair that pays attention to ergonomics; from the beginning, the seat will lose the support for the human body's waist when the user is in the reclining state, which is what we commonly call "running waist". , to the current "seat back linkage technology", which can make the user's buttocks and seat surface relatively fixed during the reclining process, eliminating the feeling of rubbing the back; When the whole body can be supported, the comfort of the leisure chair is further improved. While enjoying the relaxing posture provided by leis...

AI Technical Summary

Problems solved by technology

Although the leisure chair can control the lifting and extension of the footrest through the second electric push rod, because the second electric push rod cannot control the seat frame, the length of the footrest is limited by the length of the seat frame and the ground, so the footrest The frame cannot be designed to be longer; and the first electric push rod controls the movement of the seat frame and the chair back frame at the same time, but sometimes the human body only needs to adjust the back frame to make it tilt backward, and does not want to change the state of the seat frame, so the invention The seat frame and the back frame cannot be controlled separately
