Description

Technical Field

[0001] This utility model relates to the field of fatigue testing technology for automotive seat armrests, and in particular to a fatigue testing bench for automotive seat armrests. Background Technology

[0002] Armrests are a crucial component of car seats, and their fatigue performance directly impacts the seat's lifespan. Therefore, it's essential to test the fatigue strength of armrests. Current seat manufacturers' laboratories employ two methods: first, manually fixing a rotating device to the armrest and then rotating it. However, this method often results in unstable testing due to the rotating device's tendency to shift, and it cannot guarantee that the rotating device and armrest are concentric. Second, they use robotic arms to perform the tests, but these are expensive and cannot accurately reflect whether the test parameters meet the requirements.

[0003] Therefore, a fatigue testing bench for automotive seat armrests was designed to improve the above-mentioned problems. Utility Model Content

Figure 3 This is a perspective view of the rotating mechanism of this utility model. This utility model provides a fatigue testing bench for automotive seat armrests, including a workbench 1, a rotating mechanism 2, and a control system (not shown). The workbench 1 is movable and has casters 11 at its lower part for easy movement and can also be placed inside a temperature and humidity test chamber. The rotating mechanism 2 is mounted on the workbench 1 and is used to rotate the seat armrests for durability testing. The control system controls the operation of the rotating mechanism 2 and mainly includes digital input terminals, digital output terminals, a data acquisition module, a data storage module, and a PLC drive module. The rotating mechanism 2 includes a base 21, a vertical slide rail 22, a sliding plate 23, a rotating cylinder 24, a rotating arm 25, an adjusting plate 26, and a clamping arm 27. The base 21 is mounted on the workbench 1, and the vertical slide rail 22 is mounted on the base 21. On seat 21, slide plate 23 is connected to vertical slide rail 22 and can move up and down.
