[0002] The center armrest of the center console is a functional component frequently used by both the driver and passengers. Occupants frequently open and close the armrest to access the storage compartment. Therefore, the durability of its opening and closing operation is a crucial test for verifying its durability and reliability. During daily vehicle use, vehicles experience a wide range of environmental fluctuations in temperature and humidity. Furthermore, vehicles must also be used in hot and humid regions like Hainan, extremely cold regions like Mohe, and extremely dry and hot regions like Huoyan Mountain. To ensure that functional components like the armrest operate stably and smoothly under these challenging conditions, ensuring a reliable impression for users, tens of thousands of cycles of operation are essential. During fatigue testing, not only must operational consistency and stability be maintained, but also the safety of test personnel from these extreme conditions must be considered. To conduct these tests and avoid these issues, a new fixture for testing the durability of the center console's opening and closing operation was designed and manufactured. Utility Model Content
