Intelligent furniture-based chair frame mechanical structure with replaceable reclining state

Abstract

The invention discloses an intelligent furniture-based chair frame mechanical structure with a replaceable reclining state, relates to the technical field of furniture seats, and solves the problems that the adjustment angle of an existing seat is not fine, and a person is inconvenient to reset when lying on the seat. The intelligent furniture-based chair frame mechanical structure with the replaceable reclining state comprises a seat plate, a wheel seat is rotationally arranged in the middle of the bottom of the seat plate; a back plate is rotatably arranged on the rear side of the seat platethrough hinge connection; the back plate further comprises an air strip; by arranging the telescopic rocker and the lead screw, a mechanical angle adjusting function is provided for the chair frame,when the angle of the chair frame needs to be adjusted, the telescopic rocker can be directly rotated, the telescopic rocker is used for driving the control shaft to rotate, and the control shaft is used as power to be matched with the sliding block structure to control angle adjustment of the back plate and the push plate; the control shaft and the telescopic rocker are connected through the wormwheel and the worm, self-locking can be achieved, the stabilizing effect is good, and people can reset when lying on the seat.

Description

technical field [0001] The invention relates to the technical field of furniture seats, in particular to a chair frame mechanical structure based on a replaceable tilting state for smart furniture. Background technique [0002] The swivel chair is a computer chair, a kind of office chair, a chair with a sitting part that can be rotated. Swivel chairs can be divided into two types: half swivel chairs and full swivel chairs, and you should choose according to your own needs. [0003] After retrieval, for example, the patent No. CN107662524B discloses an adjustable seat assembly. A seat assembly is provided having a seat bottom and a seat back mounted adjacent the seat bottom. A pad is disposed on at least one of the seat bottom and the seat back and defines a seating surface. The seating surface has multiple regions. A controller is in communication with the cushion and is programmed to vary the stiffness of each of the regions along the seating surface independently. [...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a chair frame mechanical structure based on the replaceable reclining state for intelligent furniture, to solve the above-mentioned background technology. When you need to use the lever to loosen the seat shaft, you can adjust it by yourself through the body feeling. The adjustment angle is not fine, and it is inconvenient to reset when people lie on the seat. The general mechanical structure cannot prevent the seat from rolling over
