Airbag testing apparatus

Abstract

The invention discloses an airbag testing apparatus. The apparatus includes a pedestal, a testing case with a top open, a timer, a pressing assembly, a plurality of pressure sensors, a single chip microcomputer and a starting button. The testing case with the top open is mounted at the pedestal. The timer is mounted at the testing case with the top open and is intended for performing timing. The pressing assembly includes a pressing rod which conducts telescopic movement under the driving of a first motor and a pressing block which is disposed at the bottom end of the pressing rod. The plurality of pressure sensors are separately mounted at the bottom surface of the pressing block and the bottom surface of the testing case with the top open. The starting button is connected to a control end of the single chip microcomputer. An input end of the single chip microcomputer is connected to the pressure sensors. A data transmission end of the timer is connected to a data transmission end of the singe chip microcomputer. According to the invention, the apparatus can test the sealing properties of an airbag and the rigidity of the air bag, has high testing precision, and is easy to operate.

Description

technical field [0001] The invention belongs to the field of automobile equipment detection and relates to an airbag testing device. Background technique [0002] An airbag is an object that can be filled with compressed air or a liquid medium, and uses the compressibility of air and the fluidity of water to achieve protection. Airbags are used in automobiles and other devices that require cushioning protection. Therefore, the airtightness and stiffness of the airbag are extremely important performance indicators. Good airbags have good stiffness and airtightness, and poor airtightness will lead to a decrease in cushioning performance. , the poor stiffness will cause the airbag to explode easily under huge pressure, which cannot ensure the safety of the user. Therefore, it is necessary to test the stiffness and airtightness of the airbag. Most of the existing devices can only test the stiffness or airtightness. It cannot be measured at the same time, and the structure of ma...

Airbags are used in automobiles and other devices that require cushioning protection. Therefore, the airtightness and stiffness of the airbag are extremely important performance indicators. Good airbags have good stiffness and airtightness, and poor airtightness will lead to a decrease in cushioning performance. , the poor stiffness will cause the airbag to explode easily under huge pressure, which cannot ensure the safety of the user. Therefore, it is necessary to test the stiffness and airtightness of the airbag. Most of the existing devices can only test the stiffness or airtightness. It cannot be measured at the same time, and the structure of many devices is very complicated, and the operation is very cumbersome
