Example Embodiment

[0081] The present invention will be further described in detail below in conjunction with the drawings.

[0082] Such as Figure 1 to 11 , The present invention is suitable for the method for determining the design parameters of the movable mechanism of the spring return seat. The connecting hinge and force applying device (spring, pull rod) on the lower part of the chair surface are such as figure 2 Shown. One side B of the hinge is fixed to the connecting plate at the seat surface, and the other side A is fixedly connected to the seat pillar. The two are connected by a pin to form a hinge; at the same time, there is a force spring under the seat, and a hinge on B Pull rod, the other end of the pull rod is placed on A, the pull rod is covered with a force spring, when the user sits on the chair, leaning on the back of the chair, the spring provides restoring force, and the spring reaction force is loaded on the hinge at the same time on. In this way, the design parameters of...

Abstract

The invention particularly relates to a method for determining design parameters of a spring return type seat, and belongs to the technical field of seat design. A connecting hinge and a force application device are arranged at the lower part of a seat surface; the force application device comprises a spring and a pull rod; one side B of the hinge is fixed on a connecting plate at the seat surface, and the other side A of the hinge is fixedly connected with a seat pillar through a pin, so that the hinge is formed; and a force application spring is arranged on the lower portion of the seat, thepull rod is hinged to the seat B, the other end of the pull rod is placed on the seat A, the pull rod is sleeved with the force application spring, and when a user sits on the seat surface, leans against the seat back and leans back and forth, the spring provides restoring force and loads spring counter force to the hinge. In this way, design parameters of a seat moving mechanism such as the spring and the hinge can be determined according to the metal strength and the use condition of the seat.

Description

technical field [0001] The invention specifically relates to a method for determining design parameters of a spring return seat, which belongs to the technical field of seat design. Background technique [0002] In today's corporate offices, there are a large number of damaged office chairs. The failure form is that the metal connecting hinge at the lower part of the chair surface is broken and damaged, and the chair surface is separated from the lower column, resulting in a large number of office chairs being damaged and wasted. Most of the office chairs are common backrest seats. The back of the chair can rotate back and forth as the user leans back. The seat bears the alternating load transmitted by the pulling spring of the human body. Fracture failure occurs under alternating load. At present, there is no technical system design method for determining the design parameters of the office seat movable mechanism. Contents of the invention [0003] The present invention...
