Simulated dummy for testing comfort level of automobile seat

Abstract

The invention discloses a simulated dummy for testing the comfort level of an automobile seat, and the simulated dummy is characterized in that the simulated dummy comprises a simulated dummy body, and the simulated dummy body sequentially comprises a simulated skeleton layer, a simulated muscle layer, a simulated fat layer and a simulated skin layer from the inside to the outside; an upper trunkangle measuring instrument is arranged at the trunk corner of the simulated dummy body; a left thigh hip angle measuring instrument and a right thigh hip angle measuring instrument are respectively arranged at the left thigh angle and the right thigh angle of the simulation dummy body; a left thigh knee angle measuring instrument and a right thigh knee angle measuring instrument are respectivelyarranged at the left knee angle and the right knee angle of the simulated dummy body; a left foot angle measuring instrument and a right foot angle measuring instrument are arranged at the left ankleangle and the right ankle angle of the simulated dummy body, a waist area of the simulated dummy body is provided with a waist protrusion measuring scale, and pressure sensors are arranged on the back, the left thigh rear side and the right thigh rear side of the simulated dummy body. According to the invention, various sitting postures and forms of a human body can be truly simulated, and optimalsimulation of testing of the comfort level of the automobile seat by a real person can be realized.

Description

technical field [0001] The invention relates to the field of car seat comfort testing, in particular to a simulation dummy used for car seat comfort testing. Background technique [0002] With the improvement of people's living standards, the proportion of the function of the car as a vehicle for loading and commuting will gradually decrease, while the proportion of the function used for leisure and entertainment will gradually increase. As a direct support device for car users, the comfort of car seats is also increasing. It has attracted more and more attention, and people have higher and higher requirements for the comfort of car seats, and the body pressure distribution of car seats is the main indicator for testing the comfort of car seats. [0003] At present, there are two methods for detecting the body pressure distribution of car seats, namely the real person detection method and the dummy detection method. Although the real person detection method can intuitively ...

Problems solved by technology

Although the real person detection method can intuitively let the tester feel the comfort of the car seat, it is not easy to control the test process, and it has the following disadvantages: when the posture and position of the test subject change each time, the body The results of pressure distribution are different; the measurement results of different seats by the same person are not comparable; the same seat needs to be measured by multiple people, and it is difficult to analyze the measurement results; the angles of various parts of the body cannot be detected during the pressure distribution test of real people. It is not possible to more accurately understand the changes in body pressure values ​​at various angles

The dummy test method is the main method for testing the comfort of car seats. In the prior art, SAE dummy is usually used to test the comfort of car seats, because the dummy is a rigid structure, and most of the pressure of all the body is concentrated on the seat. In the cushion area, the pressure of the backrest is only a small part, and such a pressure situation cannot accurately simulate the state of a real person under real pressure; in addition, because the SAE dummy is designed according to the size and weight of the American, and the Chinese people's comfort level of the car seat There are certain differences in evaluation
