Endurance test method for central control door lock switch

Abstract

The invention discloses an endurance test method for a central control door lock switch. By alternate movement of two cylinders, the cyclic motion of the central control door lock switch in a locking / unlocking period is realized to perform endurance test on the central control door lock switch. The method comprises the following steps of: parameter setting: setting the length of a cylinder ejector rod which extends out of each cylinder, setting the pressing frequency of switch keys and setting endurance test ending conditions; lofting; rough adjustment; fine adjustment: respectively aligning the two cylinders with a locking key and an unlocking key of the central control door lock switch; endurance test: starting endurance test, and determining the frequency of the endurance test; and endurance test ending judgment: performing endurance test ending judgment, continuously performing the endurance test if the endurance test ending conditions are not met, and ending the endurance test until the endurance test ending conditions are met. The method is easy to operate, accurate adjustment can be realized, a test result is true and reliable, and the method is applicable to the endurance test of the central control door lock switch and other rocker structural switches.

Description

technical field [0001] The invention relates to a detection method, in particular to a durability test method of a centrally controlled door lock switch. Background technique [0002] The central control door lock switch of the car can lock and unlock the car door. After locking, the door cannot be opened; after unlocking, it can be opened normally. This is of great significance to improve passenger safety. The durability test of the central control door lock switch belongs to the durability test of the electrical switch. The durability test of the central control door lock switch is used to verify whether it is reliable, which plays an important role in improving the safety of the car. There are many switch durability test methods in the prior art, but due to the complexity of the test equipment used, the operation is inconvenient, for example, the cylinder and the switch button are not easy to align accurately, or it is not convenient to adjust the distance between the c...

Problems solved by technology

There are many switch durability test methods in the prior art, but due to the complexity of the test equipment used, the operation is inconvenient, for example, the cylinder and the switch button are not easy to align accurately, or it is not convenient to adjust the distance between the cylinder and the switch button within the optimal range (so The above-mentioned within the optimal range means that when the cylinder is inflated, the piston rod stretches out and the switch can be pressed, but the switch button will not be damaged due to insufficient force or too much force), which will cause damage due to reasons other than the switch itself.
