A three-year-old girl was killed by the sunroof!Measured power of electric sunroof

【The owner's family car knowledge】Recently, the death of a three-year-old girl on the Internet has become the focus of attention. The convenient and comfortable configuration of the car’s electric sunroof has become a "butcher" that strangles girls. Is this a design defect or Is it a mechanical failure, or is it caused by human care? Today we will use a few small experiments to understand how powerful an electric sunroof is.

Small experiment on sunroof anti-pinch

After reading the above accidents and understanding the principle of the sunroof anti-pinch function, our doubts seem to be focused on the reliability of the sunroof anti-pinch function? Let's try it for yourself and take a look at the sunroof's anti-pinch function. What is the effect?

We found four vehicles equipped with electric sunroofs and all with anti-pinch function, namely FAW-Volkswagen Sagitar GLI, Changan Yidong, BMW Brilliance Old 320i and Mitsubishi Pajero, which include independent, joint venture, imported and For luxury brands, the items used to be clamped are 1.25L empty beverage bottles, bananas, bitter gourd, lotus root and white radish.

1. Reliability test

experiment method:

The first thing to do is the reliability test. An editor sits in the car to control the sunroof switch, and another editor holds a beverage bottle that should not be broken and is clamped by the sunroofs of four cars 5 times to see if the anti-pinch function of the sunroof is all Can work.

The sunroofs of 4 vehicles have undergone five anti-pinch tests, and there is no problem in reliability. That is to say, the sunroof can open automatically when it encounters a softer beverage bottle during the closing process, but because of the different manufacturers' The setting of the force received when the anti-pinch is activated is different, so the deformation of the beverage bottle when the anti-pinch function is activated is also not consistent. Among them, the Sagitar GLI performed the best and received the least force during anti-pinch startup, followed by Pajero. Yidong and BMW 320i performed similarly, with beverage bottles being pinched more severely.
