Chair dynamic flexibility test device and test method

Abstract

The invention provides a chair dynamic flexibility test device and a test method. The test device comprises a chair connection tooling and a test chair, wherein the test chair is fixedly arranged on atabletop through the chair connection tooling; a laser displacement sensor is fixedly arranged on the tabletop through a laser displacement sensor connection tooling. The chair connection tooling, the laser displacement sensor connection tooling, the laser displacement sensor and a laser displacement sensor light sensing clamp are used in a matched way; through the instant collection and calculation of data, the dynamic flexibility of the tested chair can be obtained; the design level of the chair comfort performance and the product verification work efficiency are improved.

Description

technical field [0001] The invention belongs to the field of automobile engineering, and in particular relates to a test device and a test method for the dynamic deflection of a seat. Background technique [0002] As an important part of the vehicle, car seats not only play a vital role in the safety of passengers or drivers, but also directly affect the comfort experience of passengers or drivers in the car. With the gradual improvement of people's quality of life, people are now paying more and more attention to the driving and riding experience of vehicles. [0003] There are many standards to evaluate the quality of a seat, such as materials used, automatic adjustment function, heating and ventilation function, softness and hardness, etc. Among them, the softness and hardness can refer to both the seat cushion and the backrest; the softness of the backrest The degree of hardness includes the surface material, the strength of the skeleton structure and the tightness of t...

AI Technical Summary

Problems solved by technology

When the vehicle is driving on bumpy roads and the seat back is too hard, the experience of passengers may be "skinny" and inelastic like the hard seats of ordinary trains. Taking such seats for a long time will cause passengers or drivers to be extremely tired

When the seat back is too soft (loose), it will give passengers or drivers an unreliable and unsafe experience, which may affect driving safety while affecting the experience.
