Car seat headrest insertion and withdrawal force durability tester
Applicable standards:
GB 11550-2009 "Automobile seat headrest strength requirements and test methods" : This standard specifies the test methods and requirements for the insertion and removal durability of the automobile seat headrest, which is an important basis for evaluating the insertion and removal durability of the headrest.
Main parameters:
The measuring range of insertion and withdrawal force: The tester should be able to accurately measure the insertion and withdrawal force during the insertion and withdrawal of the headrest, and the measuring range is usually determined according to the design and requirements of the headrest. For example, the insertion and withdrawal force measurement range of some testers may reach 500N or higher.
Measurement accuracy: The accuracy of the insertion and withdrawal force measurement is critical to evaluating the insertion and withdrawal durability of the headrest. The tester should have a high measurement accuracy to ensure the accuracy of the test results. In general, the measurement accuracy should be ±1% or higher.
Insertion and removal stroke: Insertion and removal stroke refers to the maximum distance that the headrest moves during insertion and removal. The tester should be able to simulate the insertion and removal travel of the headrest in actual use to ensure the accuracy and reliability of the test. The specific value of the insertion and removal stroke is usually determined according to the design and requirements of the headrest.
Insertion and removal speed: Insertion and removal speed refers to the movement speed of the headrest during insertion and removal. The tester should have an adjustable insertion and removal speed to adapt to different test requirements. The specific value of the insertion and removal speed should be determined according to the test standard and the type of seat.
Cycle times: The tester should be able to set the number of plug and pull cycles to achieve a predetermined test cycle. The setting of the number of cycles should be determined according to the specific test standards and seat types to ensure the adequacy and effectiveness of the test.
Data recording and analysis: Modern car seat headrest insertion and withdrawal endurance tester is usually equipped with advanced data recording and analysis system, which can record various data in the insertion and withdrawal process in real time, such as insertion and withdrawal force, insertion and withdrawal stroke, insertion and withdrawal speed, cycle number, etc., and can conduct follow-up processing and analysis of the data. This helps users more accurately understand the headrest's insertion and removal durability.
Safety performance: The tester should have perfect safety protection measures, such as overload protection, emergency stop button, etc., to ensure the safety and reliability of the test process. In addition, the tester should also comply with the relevant electrical safety standards and mechanical safety standards.
