An office chair chassis shock absorption module

Abstract

This utility model provides a shock-absorbing module for an office chair chassis. During operation, the connecting platform connects to the support rod of the office chair. The bearing plate supports the external seat cushion. When the bearing plate is subjected to external pressure, it moves downwards. On one hand, the bearing plate compresses the buffer mechanism; on the other hand, it drives each sliding column to be inserted into and slidably connected to the limiting ring. Simultaneously, the sliding column drives the compression plate to be inserted into the sliding groove and slidably connected to the receiving platform. The compression plate compresses the compression springs as it moves downwards. In other words, the latex pad, silicone pad, high-density sponge pad, and spring pad in the buffer mechanism cushion the bearing plate. Furthermore, two compression springs cushion the bearing plate through the compression plate and sliding columns. This office chair chassis shock-absorbing module provides excellent cushioning performance.

Description

Technical Field

[0001] This utility model relates to the field of office chair shock absorption, and in particular to an office chair chassis shock absorption module. Background Technology

[0002] Office chairs refer to various chairs provided for convenience in daily work and social activities. Office chairs can be divided into narrow and broad definitions. Narrowly defined, an office chair refers to a chair with a backrest used for desk work while seated. Broadly defined, an office chair includes all chairs used in offices. Office chairs can be categorized by material composition, such as genuine leather, PU leather, fabric, mesh, and plastic. They can also be categorized by usage, such as executive chairs, work chairs, staff chairs, manager chairs, conference chairs, visitor chairs, and ergonomic chairs.

[0003] However, the shock absorption module is a crucial component of office chairs, enhancing their comfort. Traditional office chairs with cushioning and pressure reduction features, such as the one described in patent application CN201611234319.6 (invention title: A Comfortable Office Chair with Shock Absorption and Cushioning Function), have relatively poor cushioning performance. Utility Model Content

[0004] Therefore, it is necessary to provide an office chair chassis shock absorption module to address the technical problem that traditional office chairs with cushioning and pressure reduction have poor cushioning effects.

[0005] An office chair chassis shock absorption module includes: a support platform, a compression mechanism, and a buffer mechanism; The receiving platform has a buffer groove in the middle area, and a sliding groove on both sides of the buffer groove. A limit ring is provided on the inner wall of the opening end of each sliding groove. A connecting platform is provided at the bottom of the receiving platform. The extrusion mechanism includes a support plate and two extrusion assemblies; the two extrusion assemblies are symmetrically arranged on both sides of the support plate; each extrusion assembly includes a sliding column, an extrusion plate, and a compression spring; the extrusion plate is connected to the support plate via the sliding column; the sliding column is adapted to the limiting ring, inserted into the limiting ring, and slidably connected to the limiting ring; the extrusion plate is adapted to the sliding groove, inserted into the sliding groove, and slidably connected to the receiving platform; the compression spring is adapted to the sliding groove, housed in the sliding groove, one end of the compression spring is connected to the bottom of the sliding groove, and the other end of the compression spring abuts against the extrusion plate; The cushioning mechanism includes a trouser bag, a latex pad, a silicone pad, a high-density sponge pad, and a spring pad; the latex pad, the silicone pad, the high-density sponge pad, and the spring pad are all adapted to the trouser bag, and the latex pad, the silicone pad, the high-density sponge pad, and the spring pad are filled into the trouser bag in descending order of height; the trouser bag is adapted to the cushioning groove, and part of the trouser bag is inserted into the cushioning groove and connected to the receiving platform.

[0006] In one embodiment, the connecting platform and the receiving platform are integrally formed.

[0007] In one embodiment, the receiving platform is a cylindrical structure.

[0008] In one embodiment, the receiving platform is a quadrangular prism structure.

[0009] In one embodiment, the connecting platform is a cylindrical structure.

[0012] In one embodiment, the sliding column is a cylindrical structure.

[0013] In one embodiment, the sliding column is a quadrangular prism structure.

[0014] In one embodiment, the extrusion plate is a circular plate structure.

[0015] In operation, the aforementioned office chair chassis shock absorption module uses a connecting platform to connect with the support rod of the office chair. The load-bearing plate supports the external seat cushion. When the load-bearing plate is subjected to external pressure, it moves downwards. On one hand, the load-bearing plate compresses the cushioning mechanism; on the other hand, it drives each sliding column to be inserted into and slidably connected to the limiting ring. Simultaneously, the sliding column drives the compression plate to be inserted into the sliding groove and slidably connected to the receiving platform. The compression plate compresses the compression springs as it moves downwards. In other words, the latex pad, silicone pad, high-density sponge pad, and spring pad in the cushioning mechanism cushion the load-bearing plate. Furthermore, the two compression springs cushion the load-bearing plate through the compression plate and sliding columns. The aforementioned office chair chassis shock absorption module provides excellent cushioning performance. Attached Figure Description
