AI Technical Summary
Automotive air conditioning control panels are prone to malfunction in complex vibration environments due to loose wiring harnesses, micro-cracks in solder joints, and detachment of clips. Existing testing equipment cannot effectively simulate the vibration conditions during vehicle operation, resulting in discrepancies between laboratory test results and actual usage.
A test bench for automotive air conditioning control panels was designed. It simulates the vibration of a vehicle during driving by using components such as a vibration motor, eccentric journal, connecting rod, and vibration slider. Combined with a clamping structure and vibration sensors, it monitors and adjusts in real time to ensure the stability of the panel under high-frequency impact.
Effectively identify potential defects inside the panel, avoid functional failure after installation, improve product quality, reduce after-sales noise complaints, and enhance brand reputation.
