Equipment used for air sac test

Abstract

The invention discloses equipment used for an air sac test. The equipment used for the air sac test comprises a base, an air sac test box body, a timer, a telescopic compression rod which can move up and down when driven by a first motor, a compression block arranged at the bottom end of the telescopic compression rod, multiple pressure sensors, a singlechip and a touch display, wherein the air sac test box body is arranged on the base and comprises a test box body and a box cover, a through hole through which the telescopic compression rod can penetrate is formed in the box cover, the box cover is movably arranged on the test box body, and an air sac air charging hole is formed in the bottom of the test box body; the timer is arranged outside the test box body; multiple pressure sensors are respectively arranged on the bottom surface of the compression block and the bottom surface of the test box body; a data transmission terminal of the touch display and a data transmission terminal of the timer are respectively connected with the singlechip, the input terminal of the singlechip is connected with each pressure sensor, and the output terminal of the singlechip is connected with the first motor. The equipment used for the air sac test can test sealing property of an air sac, also can test stiffness of the air sac and is high in test precision and easy to operate.

Description

technical field [0001] The invention belongs to the field of automobile equipment detection, and relates to equipment for airbag testing. 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 ...

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
