Physical performance detecting device and platform for stroller

Abstract

The invention discloses a physical performance detecting device for a stroller. The device comprises an acceleration detection module, a displacement detection module, a stress detection module, and amaster control module; the acceleration detection module detects and obtains acceleration data during up-down vibration of the stroller; the displacement detection module detects and obtains vibration amplitude data during up-down vibration of the stroller; the stress detection module detects and obtains stress data of a bearing rod of the stroller; and the master control receives the acceleration data, the vibration amplitude data and the stress data in real time, processes the data, and obtains a real-time dynamic result and a final statistical result. The final statistical result comprisesthe maximum, the minimum, the mean value, the amount of vibration bouncing quantity data and the mean value of the vibration bouncing quantity data. The method can be used for design and developmentof a factory product, check in a lab equipment period, and capability verification projects in a lab, and is technically characterized by diversified data, real-time collection and accurate detection.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a physical performance detection device and platform of a children's trolley. Background technique [0002] The domestic safety standard for children's strollers GB 14748-2006 "Safety Requirements for Children's Strollers", in which 4.15 dynamic durability test item stipulates that after being tested according to the test method of 5.18, the children's stroller should not have any influence on its safety. damage. According to the test method of clause 5.18, the stroller will be continuously subjected to 36,000 cycles of fatigue tests on the irregular surface test equipment, and then the safety evaluation of the test samples will be carried out. Internationally, the EU product standard EN 1888-2018 "Children's care products - children's wheeled transport equipment: safety performance and test methods" also adopts basically the same irregular surface test items, equi...

AI Technical Summary

Problems solved by technology

[0003] (1) In the standard, the test method only stipulates the principle of the test, the size and layout of obstacles, and does not specify the conveyor belt carrying obstacles, resulting in the conveyor belt materials closely related to the test results in the test equipment of each laboratory. , Conveyor belt support mode, conveyor belt cycle length and test times are significantly different. Therefore, the same product will produce different results in different laboratories, and ultimately affect the evaluation of product safety performance.

[0004] (2) The difference in sample clamping and fixing methods and fixing effects leads to differences in test results in different laboratories

During the test, due to the difference in sample clamping conditions, the product test results are affected

[0005] (3) As a fatigue test item for durability, the test time is usually longer

[0006] Therefore, in order to solve the above-mentioned sample testing problems, it is necessary to take measures such as inter-laboratory verification, inter-laboratory proficiency comparison, and implementation of proficiency testing plans to achieve consistency in inter-laboratory sample test results. The technical means of the period verification of the test equipment for the durability test project or the qualitative evaluation of the capability verification of the dynamic durability test project
