Embodiment Construction

[0043] Hereinafter, the present invention will be described in detail with reference to the drawings and examples.

[0044] figure 1 It is a flow chart of the safety belt buckle durability test method of the present invention.

[0045] Such as figure 1 As shown, at first, in step S101, power is turned on to make the deadbolt return to its original position, that is, the solenoid valve of the buckle button is opened to open the buckle button, so that the deadbolt remaining in the buckle is released, and the time delay A first length of time (for example, 1 second). The delay here is the process time for the lock to release the spring and the lock tongue to rise, that is, it takes one second from the lock button is pressed to the lock tongue bounces back to its original position.

[0046] Then, in step S102, detect whether there is a deadbolt in the buckle (that is, detect whether the deadbolt still exists in the buckle), if yes, it means that the buckle is stuck on the deadb...

Abstract

The invention provides an experimental control method for a seat belt buckle button, which includes: before the station button is pressed, power is turned on to return the deadbolt to its original position; after the station button is pressed, the solenoid valve for the deadbolt is opened, Make the lock tongue drop and insert the lock buckle, and check whether the third time length has passed, if yes, then detect that the lock tongue is in place, otherwise continue to wait; if the lock tongue is in place, open the lock button solenoid valve, and detect Whether the fourth length of time has passed, if yes, then detect whether there is a deadbolt in the buckle, otherwise continue to wait; if it detects that there is a deadbolt in the buckle, then perform a fault alarm, otherwise close the solenoid valve of the buckle button; When the predetermined number of experiment cycles is reached, the experiment is stopped; otherwise, the step of opening the bolt electromagnetic valve is skipped. In addition, corresponding control devices are provided. The method and device of the invention are simple and easy to implement, have good stability, timeliness, accuracy and operation safety, and improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of auto parts detection, in particular to a safety belt buckle durability experiment control method and a device thereof. Background technique [0002] The seat belt buckle is an important part of the car safety protection device. The existing seat belt buckle durability test process mainly relies on manual or simple mechanical buttons and relays for process control. Due to the technical requirements of the relay itself, such as the need for time delay, the limitation of the number of opening and closing, and the large operating current, etc., there are many faults in the whole experiment process, there are defects such as leakage and slow response, which makes the work efficiency low and stable. , Poor operation safety. Contents of the invention [0003] In order to solve the above problems, the present invention provides a control method and device for a seat belt buckle durability experiment, so as to...
