Automotive door locks are critical safety components that directly affect driving safety.
To adapt to complex high and low temperature climates across different regions, major OEMs impose extremely strict requirements on the temperature resistance and durability of door locks. All door lock products must undergo repeated opening and closing tests ranging from tens of thousands to even millions of cycles under extreme temperature conditions from -40°C to +80°C before mass production. The stability of the motor used in the testing equipment is a key factor in determining test accuracy and whether the testing process can proceed smoothly.
Customer Key Requirements
According to mainstream OEM testing standards, equipment development must meet two core requirements, which are also major technical challenges in the industry:
01. Adaptation to extreme environmental testing
The system must simulate extreme high and low temperature conditions from -40°C to +80°C, repeatedly testing the opening/closing behavior and structural stability of the door lock under different temperatures. This helps identify potential component failures caused by temperature variations in advance, ensuring the final product fully meets OEM acceptance standards.
02. Long-term high-precision operation
Door locks must undergo durability testing for tens of thousands to millions of continuous cycles. This requires the motor to maintain uniform output and fast response throughout the entire process, without issues such as vibration or speed fluctuation, ensuring each set of test data remains accurate and consistent, and supporting long-term uninterrupted stable operation of the test system.
