Automobile glass elevating switch button endurance test device and method thereof

Abstract

The invention discloses an automobile glass elevating switch button endurance test device and a method thereof. The device comprises an upper shifting pressure regulating valve, an upper shifting air cylinder, an upper shifting buffer device, a button Y-shaped shifting rod, a lower shifting buffer device, an upper shifting operation indicating lamp, a lower shifting operation indicating lamp, a lower shifting air cylinder, a lower shifting pressure regulating valve, a shifting rod upper limiting plate, a lower return spring, a shifting piece hinge, a lifting switch button, an upper return spring, a shifting rod lower limiting plate and a test bed. The device has the advantages that the upper return spring and the lower return spring are installed, the Y-shaped shifting rod can return to the middle position after shifting the lifting switch button, meanwhile, impact force of the air cylinder is reduced in the air cylinder braking process, and the stability of a test sample piece is effectively guaranteed; the lever principle is formed through design, the braking force of the air cylinder is reduced, and the air cylinder can be stably tested under the low-temperature condition; and through limiting control, the lifting switch button is not damaged in the process that the cylinder extends out to form the lever principle, and the stability of a test sample piece is effectively protected.

Description

technical field [0001] The invention relates to a switch button endurance test device and a method thereof, in particular to an automobile glass lift switch button durability test device and a method thereof, belonging to the technical field of automobile testing. Background technique [0002] At present, the test bench for the durability test of the automotive glass lift switch button is to use the cylinder to directly drive the switch. The long-term durability test of the cylinder directly drives the lift button, causing varying degrees of damage to the switch button, which cannot reach the 8 of the key pressure test standard. -10N test standard, and under low temperature conditions, the cylinder braking force must be strengthened to achieve braking, so it is easier to damage the sample and fail to meet the expected requirements of the test. [0003] Based on this, the present application proposes an automobile window lift switch button durability test device and a method ...

Problems solved by technology

[0002]At present, the test bench for the durability test of the automotive glass lift switch button is to use the cylinder to directly drive the switch. The long-term durability test of the cylinder directly drives the lift button. The buttons cause different degrees of damage, which cannot meet the 8-10N test standard of the button pressure test standard, and the braking force of the cylinder must be strengthened to achieve braking under low temperature conditions, so it is easier to damage the sample and fail to meet the expected requirements of the test
