Technical Field
[0001] The utility model relates to the technical field of automobile component testing, and more specifically, to a novel automobile central control front armrest assembly fatigue testing fixture. Background Art
[0002] The car center control armrest is a component that is used very frequently in car interior products. During daily use by passengers, the driver or passengers need to adjust the armrest according to their driving habits or usage habits. For some armrests with storage boxes, passengers will adjust the armrests when opening and closing the storage boxes. During use, the armrests will be adjusted too many times and the adjustment mechanism will wear out, causing noise, jamming, and failure of the locking function, etc., which will affect the passenger comfort. Therefore, it is very important to detect armrest adjustment fatigue.
[0003] Traditional central control testing uses a car body. Since the car body itself is very heavy, it is extremely inconvenient for testers to place the car body in the experimental environment chamber. When conducting fatigue tests under high and low temperature extremes, personnel entering the environment chamber will cause harm to human health. In view of this, a new type of automobile central control front armrest assembly fatigue test fixture is urgently needed in the industry. Utility Model Content
