Windows pinch hand function refers to the window glass up the process, if you encounter resistance, it will automatically drop to prevent the folders in hand and so on. General car window on the pinch hand function are relying on " tactile " to control , the control system in the glass up process once the glass face of pressure is detected , it will stop the glass up and down the glass directive to prevent clip wounding .
        According to the Throttle Valve  Kero understand the pinch function windows , window glass rises in the process, if you encounter an obstacle , it will automatically stop. However, due to improper operation or failure , window anti-trap function can sometimes fail , once caught the child , will be very dangerous.

        It was against the sunroof pinch function did an experiment with obstacles prevent the window glass up and found to be pinched off lettuce , water bottles caught flat , large cucumbers caught out a deep scar .
        Later, the car manufacturers to improve electric windows in two ways , one is to pull up on the switch to formula , rather than left as press -in , so to avoid inadvertently make windows may rise ; Second, the car windowpane designed pinch type, once you encounter any resistance , it will immediately drop to a minimum. Therefore, in the purchase of vehicles , preferring no leather , no sunroof , but also choose a pinch function of the window , to prevent the risk of entrapment occupants .

       General car is equipped with anti-pinch windows are relying on " tactile " to control , the control system in the glass up process once the glass face of pressure is detected , it will stop the glass up and down the glass directive to prevent entrapment people . But more advanced car is also equipped with one kind of rely on " visual " to control the anti-trap function . Rise in the glass above the glass found during any foreign object , it automatically stops rising and instead fall , so no direct contact with foreign objects into the glass . Such a system from the infrared transmitter and receiver components mounted on the window interior parts , which can continuously and accurately scan the designated area , away from the edge 4 of the window frame opening 200 mm range , if detected glass foreign body will stop rising , so it was called " no-touch pinch smart glass ."
       To reduce the risk of injury window glass for auto glass lifter should have pinch function , next year will be the introduction of relevant regulations require new vehicles should be fitted with anti-trap feature a glass elevator .

       According to the Throttle Valve Kero understand Auto Glass lifter pinch technology will be able to minimize the risk of injury , its working principle is: When the window glass encounters an obstacle between the frame and the car , the sensor can detect abnormalities, and induction into the larger motor deceleration will immediately make up the windows to stop and reverse the decline.
