Description

Technical Field

[0001] The utility model relates to the technical field of automobile component testing and inspection, and more specifically, to a novel split armrest fatigue test fixture. Background Art

[0002] As car ownership grows, consumers are demanding higher standards for center console armrests in terms of environmental friendliness, comfort, and intelligence. Major automakers are increasingly focusing on armrest fatigue and durability testing. To ensure stable functionality throughout their lifecycle, armrests must undergo tens of thousands of fatigue and durability tests at varying temperatures. Manual operation cannot guarantee the stability and consistency of test movements, and manual fatigue testing at extreme temperatures can be harmful to the tester's health. For these reasons, an alternative to manual fatigue testing for armrests is urgently needed in the testing industry. Utility Model Content
