Embodiment 1

[0039] refer to figure 1 , figure 2 , a passenger car seat ventilation function consistency test device provided by the present invention includes a test box 1, a low temperature box 2, a thermal imager 3, a wire grid dummy 4, a computer, and a lin box; wherein the low temperature The box 2 is provided with an air inlet, and the low-temperature box 2 is connected with the test box 1 through a pipeline 6; the low-temperature box 2 is used to cool the incoming air, and the ventilation fan of the seat to be tested will guide the cold air into the test chamber. Box 1; the seat 5 to be tested is placed in the test box 1, and after it is sealed with the test box 1, the seat cushion and the backrest position are leaked out, and the ventilation fan of the seat to be tested is electrically connected to the lin box, and the lin box is connected to the lin box The computer is electrically connected, and the ventilation fan is controlled by the computer to start, stop and rotate speed; ...

Embodiment 2

[0042] A passenger car seat ventilation function consistency test method, the method comprises the following steps:

[0043] Step S1, place the seat to be tested in the test box, seal it, leak the seat cushion and the backrest position, and ensure that the air on the front surface of the seat is separated from the air on the rear surface of the seat; The mesh dummy is placed on the seat to be tested, and the outer contour of the wire mesh dummy must conform to the SAE-profile (see figure 2 and Chinese patent CN211205774U);

[0044] Step S2, store the sealed test box and the steel wire mesh dummy in a high temperature box at 40°C±0.5°C and a relative air humidity of 30%RH±1.5%RH for 6 hours; Set at 11°C±0.5°C;

[0045]Step S3, connect the power supply of the thermal imager, and connect the computer with the thermal imager, and at the same time connect the ventilation fan of the seat to be tested to the power supply and the lin box, connect the lin box to the computer, load t...

Abstract

The invention relates to a passenger car seat ventilation function consistency test method and test device. The device comprises a test box, a low-temperature box, a thermal imager, a computer, a lin box and a steel wire grid dummy; the low-temperature box is connected with the test box through a pipeline and is used for cooling incoming air, and cold air is guided into the test box through a ventilation fan; a to-be-tested seat is placed in the test box, the positions of a seat cushion and a backrest are exposed after the to-be-tested seat is sealed with the test box, the ventilation fan is electrically connected with the lin box, and the lin box is electrically connected with a computer; the steel wire grid dummy is placed on the to-be-tested seat, the thermal imager is arranged right in front of the steel wire grid dummy, the thermal imager is electrically connected with the computer, the computer controls the thermal imager to carry out video shooting on the to-be-tested seat, and obtains temperature information corresponding to a cushion and backrest test area at a specified time point according to shot videos. The method and device can accurately test the consistency of the ventilation function of the passenger car seat, and is simple in structure, convenient to operate and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of seat ventilation detection, and in particular relates to a method and a test device for testing the consistency of the ventilation function of a seat of a passenger car. Background technique [0002] Seat ventilation is an important and practical function in the seat comfort configuration, which is of great help to the comfort experience of the seat occupants. Currently, most passenger cars have this configuration. Consistency of seat ventilation function is an important indicator for examining the performance of seat ventilation, but so far the industry has not promulgated a unified method and standard for measuring the consistency of passenger car seat ventilation function. Contents of the invention [0003] In view of the above-mentioned technical problems and defects, the purpose of the present invention is to provide a method for testing the consistency of ventilation function of passenger car seat...
