Problems solved by technology

[0004] In view of this, in order to solve the problems of difficult definition of the hardness index of the real car in the ring state, no quantitative index in the development process, unstable subjective evaluation of the product, and difficult determination of the pass rate, the present invention proposes a method that can be carried out under real car conditions. Hardness test, the car seat hardness-in-the-loop test equipment and test method, which do not destroy the entire seat surface, are simple to operate, can objectively and accurately test the seat hardness, and the test results are consistent with the subjective evaluation. The testers provide the test according to the present invention. Equipment and test methods can be used to measure and evaluate the hardness of real vehicle seat seats

Embodiment 1

[0069] The vehicle seat hardness-in-the-loop test equipment and test method were used to press the measurement point of the A seat by 30 mm, and then unload at the same speed. Read the force value at 30mm on the curve, the first time is 150N, the second time is 158N, the third time is 165N, and the average value is 157.7N.

Embodiment 2

[0071] The vehicle seat hardness in-ring test equipment and test method are used to press the B seat by 30mm at the same point, and then unload at the same speed. Read the force value at 30mm on the curve, the first time is 173N, the second time is 181N, the third time is 190N, and the average value is 181.3N.

[0072] From the results obtained in Example 1 and Example 2, it can be seen that the force of seat B is 23.6 N greater than that of seat A by pressing the same point at the same depth, indicating that seat B is harder than seat A. If the enterprise takes more than 180N as the unqualified index of seat hardness, the B seat is judged to be unqualified.

Embodiment 3

[0074] Using the vehicle seat hardness-in-the-loop testing equipment and testing method, the hardness comfort test is carried out on the left and right A and B points of a certain seat along the vehicle transverse direction. Corresponding point positions, press 30mm into the two points respectively, then unload at the same speed, and read the force value at 30mm on the curve. If point A is 150N for the first time, 158N for the second time, and 165N for the third time, the average value is 157.7N; point B is 173N for the first time, 181N for the second time, and 190N for the third time, and the average value is calculated. The value is 181.3N. Point B is 23.6N larger than point A, indicating that point B is harder than point A. If the difference between the left and right of the company exceeds 20N as the unqualified index of seat hardness, the seat will be judged as unqualified.

Abstract

The invention provides a vehicle seat hardness-in-the-loop testing equipment and method, comprising a mobile main support, a hardness testing module and a mobile sub-support; the mobile main support comprises a column, a wheel set at the bottom of the column, one end of which is connected with The beam connected with the column; the hardness test module is connected with the beam and can move along the length of the beam, and the hardness test module includes a sliding table assembly, a force sensor connected with the lifting end of the sliding table assembly, and a pressure plate connected with the force sensor; The mobile sub-support includes a sub-column, a sub-wheel set at the bottom of the sub-column, and a beam limiter located on the sub-column. The vehicle seat hardness in-ring test device of the present invention can perform hardness test under real vehicle conditions, does not damage the entire seat surface, is simple to operate, can test the seat hardness objectively and accurately, and the test results are consistent with subjective evaluation.

Description

technical field [0001] The invention belongs to the field of vehicle performance testing, and in particular relates to a vehicle seat hardness-in-the-loop testing device and a testing method, which can perform hardness testing in a real vehicle-in-the-loop state. Background technique [0002] At present, the comfort of car seats has become a key concern for customers when purchasing a car. Seat hardness is one of the contents that customers can clearly perceive and evaluate. Fatigue and other aspects are affected. Japanese cars are often designed with a softer seat surface to improve the short-term seating comfort of customers and give customers the feeling of a comfortable sofa. The German car seat design is relatively tough, which can effectively support the body when the customer is driving for a long time, without being too tired, and ensuring better dynamic comfort. [0003] The softness design of the seat is a systematic project, which involves various factors such a...
