How to safely use skylights as well as domestic car owners to some of the ignorant habit but lack the attention they deserve . Internet search is not difficult to find , because the electric windows or sunroof children injured as a result never stopped in earlier this month , Anyang, Henan 's almost the same as a little girl playing with skylights and killed , but fortunately did not cause the rescue in a timely manner serious injury. Why electric windows with safety design has frequently become a threat to the safety of children's lives Blackhand ? This is from the electric sunroof anti-pinch feature works start.
According to Yu- fan clutch special note , the current production of automotive electric sunroof pinch function implemented in two ways , one is by measuring the sunroof motor current changes to complete, the other is to control the use of Hall sensors , by detecting the motor the speed of change and travel to achieve pinch function . Pinch principle is not complicated , but the operation still need to solve some problems, we all know , windows or skylights in the lifting process will encounter much resistance , if dust or debris in orbit lift more, run the glass itself resistance is relatively large. So if the anti-trap function design is too sensitive , then it may affect the normal operation of the window , which means that even if the windows are equipped with anti-trap function , in effect before it must encounter greater resistance . Pinch does not mean not hurt , especially for children's tender neck , in the anti-trap function may have been previously involved in a possible injury suffered external force . In addition, most of the anti-pinch feature will detect the resistance when the window motor reversal lowered the window to unlock the danger, but also part of the window just pinch off the motor power can do to make it stop working, do Although the clip can be avoided more serious injury, but they do not have the ability to control the power window buttons children, skylights card if the neck , it means that adults must come down from the car window lift danger if adults and children will be very dangerous negligence then . In addition, the sunroof anti-pinch function does not belong to the vehicle inspection part, due to the circuit failure pinch function failure is possible .
Then, set the value of the resistance sunroof pinch how much is safe in this area have a national standard? According to special margin fan clutch understood that the National Car Quality Supervision and Inspection Center Liu Yuguang , deputy chief engineer , told reporters , as of now , no one in the industry for car sunroof anti-card safety design a unified standard , each car manufacturers are based on their own experience or design of the experimental data .
While some car sunroof with automatic pinch function , but as the child is concerned , he does not know how to properly operate the buttons , once misuse is still very dangerous, and some models of the sunroof closes automatically with flameout function , in case the vehicle flameout , the child's head is still out of the window , it is easy to pinch .
