Technical Field
The invention relates to the field of automobile accessory testing, in particular to a detection method of anti-pinch strip resistance value testing equipment.
Background
Along with the development of automobiles, a plurality of middle-high-grade cars are provided with electric skylight, middle sliding doors, rear tail doors and other devices, so that the operation of opening and closing the car doors and the car windows is greatly facilitated, a more convenient and comfortable riding environment is provided for passengers, and potential dangers are brought at the same time. That is, when the passenger naturally puts his/her hands on the door frame or head out of the skylight, the passenger may be injured by the automatic sliding door or skylight, and the arrangement and design of the anti-pinch device are particularly important.
The anti-pinch strip is used as a key safety part and is widely applied to safety systems, the action mechanism of the anti-pinch strip is that a conductive electrode inside the anti-pinch strip is contacted through physical contact, so that contact resistance is generated, and the triggering of an obstacle is judged through the change of the voltage of an output end. When the electric door and window using the anti-pinch strip is closed, the electric door and window can automatically stop after meeting certain resistance, or automatically change the glass ascending stroke into the descending stroke, thereby preventing drivers and passengers from pinching (especially for naughty people in small basins).
The anti-pinch strip is required to be subjected to performance detection after being produced, the existing mode is that a pressing block is used for pressing down a preset stroke, detection is carried out after the stroke is finished, and whether the resistance value of the anti-pinch strip meets the performance requirement is detected. But the quality of the anti-pinch strip produced does not necessarily meet the standard. The following problems are found in the detection process of the anti-pinch strip at present: when the pressure block is pressed down to a preset stroke, the force value applied to the pressure block exceeds the protection program of the detection equipment, so that the equipment automatically stops and gives an alarm, and valid data cannot be detected.
Aiming at the problems, the engineer optimizes the resistance value test equipment and the detection method of the anti-pinch strip so as to solve the problems in the prior art.
