Seat creep experiment platform

Abstract

The invention discloses a seat creep experiment platform, which is composed of a base, an upper platform face, four hydraulic oil cylinders, a middle support hydraulic oil cylinder and a creep device. The four hydraulic oil cylinders and the middle support hydraulic oil cylinder are arranged on four corners between the base and the upper platform face. The upper end and the lower end of each hydraulic oil cylinder are respectively hinged with the base and the upper platform face in spherical face mode. The middle support hydraulic oil cylinder is arranged at the middle position of the base and the upper platform face, the lower end of the middle support hydraulic oil cylinder is fixed on the base, the upper end of the middle support hydraulic oil cylinder is hinged with the bottom of the upper platform face in spherical face mode, and the creep device is arranged on the upper platform face. The creep device is composed of a support column, a transverse frame, a horizontal counter weight, a vertical frame, two vertical counter weights, an adjusting screw and a seat fixing seat. The horizontal counter weight is fixed at the middle of the transverse frame through the screw, and the vertical counter weights are respectively fixed on two sides of the upper end of the vertical frame. The seat creep experiment platform can detect creep performance of the soft portion of the seat at the design stage to judge whether the seat can completely meet requirements for seat creep experiments.

Description

technical field [0001] The invention relates to a seat test bench, in particular to a seat creep test bench. Background technique [0002] At present, the soft part of the vehicle seat cushion is mostly made of foam brown silk, and these materials will undergo permanent deformation or creep after a long time of bearing weight. Once the soft part of the seat creeps, the comfort of the seat will be improved. The resistance will be greatly reduced, but at present there is no more effective experimental equipment for detecting the creep characteristics of the soft part of the seat. Contents of the invention [0003] The object of the present invention is to provide a seat creep test bench. The present invention enables the seat to detect the creep performance of the soft part of the seat at the design stage to judge whether it fully meets the requirements of the seat creep test. [0004] The present invention is composed of a base, an upper table, four hydraulic cylinders, an...
