The hidden door handle caused another tragedy and became the biggest stumbling block for the owner to escape from the accident

In order to better wind resistance performance and a more sporty appearance, more and more models began to use the design of hidden door handles, especially on electric cars, based on the consideration and requirements of technological design and increased mileage, this device that was originally only seen in high-end models with hundreds of thousands of large has become the standard configuration of one or two hundred thousand family cars.

Recently, in an accident on a highway section, a woman was trapped in the car because of the design of the hidden door handle and could not be rescued. According to the video taken at the scene of the accident, the two sides of the accident were a family car and a truck, and after the collision, the family car was squeezed under the truck, and the front of the car was seriously damaged, probably due to a problem with the electronic control system, which caused the hidden door handle to be unable to be spread out, and the injured in the car could not be rescued.

However, this is not the first time that hidden door handles have been accidental, in 2019, an anesthesiologist in the United States drove a Tesla Model S into a palm tree on the side of the road, and when firefighters arrived, they were unable to open the door and could not be rescued, and finally the fire engulfed the life of the car and the anesthesiologist.

In addition to not being able to open in a car accident, even in the winter in the north, many Northeast car owners with hidden door handles have taken the lead in understanding the dilemma that the door handle is frozen and cannot be opened.

Now that we know what to expect with concealed doorknobs, let's take a look at the current state of technology for this thing. What we want to tell you here is that, at least for now, there is no problem with hidden door handles in terms of technical path and cost control. This technology, which was first manufactured by the German team and gradually standardized by the market and gradually developed in the Chinese market, has reached the level of "the latest generation of products with greatly improved ice-breaking capabilities, emergency devices in case of accidents, and a significant reduction in costs".

But the technology does not mean that it can be realized! The cost of these technical parts is very high, and the focus is on what technical path and technical specifications of the products car companies choose.

At the beginning of the design, the hidden door handle will basically be equipped with an emergency mechanism, which will give the door handle a signal when a collision occurs, and will automatically push it open after receiving the collision signal. This mechanism can fail due to damage to the electronic components in some violent collisions. However, some door systems do not have the entire collision signal connection, resulting in the entire car not being supported even if the door handle is supported.

Let's finally talk a little about the necessity of concealed doorknobs. The brainwashing of OEMs and sales to everyone is to "build cognition", which is based on the fact that hidden door handles can reduce wind resistance and increase cruising range. But Zhiyi Auto wants to tell you an industry situation that even if you don't use hidden door handles, the Mercedes-Benz CLA ten years ago achieved a wind resistance of 0.22Cd, and the current wind resistance performance of the BMW 3 Series can also reach 0.23Cd, these cars do not use hidden door handles, but the result is similar to the current model. No car company will make a model equipped with hidden door handles and a model equipped with ordinary door handles to do wind resistance comparison, which is a trap.

So the hidden door handle is only the advantage of "good looking", but is it important? The answer is yes, because this device, which was originally only placed on hundreds of thousands of large models, has been transferred to ordinary people's homes by technology, and it must have fans. As for safety, the technology has arrived, and whether it is used or not depends on the conscience of the car companies.
