In the past few days, the automobile circle has basically been swiped by the Beijing Auto Show, after all, this international auto show has not only released hundreds of new cars, but also gathered various bigwigs. However, although the auto show is very lively, there is a serious traffic accident about the "three drivers and passengers killed" in Shanxi Province of Wenjie M7, which also sparked heated discussions on the Internet, and even rushed to the hot search on Weibo.
According to the video circulating on the Internet, a black Wenjie M7 rear-ended a sprinkler truck at high speed, the front cabin of the Wenjie M7 was on fire, the entire front of the car collapsed very seriously, and the A-pillar on the front side of the sprinkler was suspected to have been bent. At the same time, the accident video also shows that the hidden door handle of the M7 is suspected to have not popped out, so a sanitation worker and passers-by are smashing open the rear window glass to try to save people, and in the follow-up video, the M7 has burned out.
In this regard, the official Wenjie made a statement: according to the national platform data access management regulations, it was learned that the speed of the vehicle was 115km/h when the accident occurred, the airbag was opened normally, and the characteristics of the power battery pack were normal. However, although the current specific investigation results can still be subject to the follow-up traffic police department's report, there are also many questions on the Internet, among which whether the hidden door handle is the key to hindering the rescue has also become a hot topic recently.
As we all know, now in new energy vehicles, the design of hidden door handles is very popular, and its benefits are also obvious, one is that this design can make the door handle and the body integrate, looking more beautiful, more advanced, and more technological, and the other is to reduce wind resistance to a certain extent, thereby improving aerodynamic performance. So we can also see that in new energy vehicles above 200,000 levels, hidden door handles have basically become the standard.
However, it is this hidden design that actually has a lot of hidden dangers. Although the serious accident caused by the M7 has no direct connection with the hidden door handle, it is important to know that the new energy vehicle equipped with a large-capacity battery is likely to burn and catch fire in the event of a collision, and this speed is still very fast, so the occupants must open the door to escape at the first time, and whether the door can be opened from the outside in time has become the key to rescue.
Compared with the traditional door handle, the hidden door handle is undoubtedly much more complicated, the vehicle should be unlocked in the state of power, through the internal motor to push out the door handle, which means that any link in the impact process will cause the handle to bounce off, and the outside people want to save the people in the car, the first reaction must be to pull the door, but if the entire control system fails due to a violent impact, the door handle will not pop out and miss the opportunity.
Many people may question whether the door handle is hidden or not is not the key, it still depends on whether the vehicle has the function of automatic unlocking after a collision, because sometimes in the event of a serious accident, even if there is a door handle, it cannot be opened if it is locked. But now the hidden doorknob doesn't even give a chance to try to pull, so naturally it is even more useless.
In fact, the configuration of hidden door handles has been frequently complained about, because in addition to the relative safety risks, its practicality has also been questioned. For example, in winter, because the weather in the north is too cold, there may be an embarrassing situation that it cannot be frozen, and even many car owners have come up with ways to put tape on the hidden door handles and pour hot water. Just imagine, if this is the kind of traditional doorknob that used to be pulled directly, would you still need to put so much thought into this function?
Write at the end
In the era of new energy vehicles, we have indeed seen a lot of higher-tech technologies, after all, consumer demand is upgrading, and automotive products will definitely be improved. But no matter what stage of technology development, safety is still the first priority of the car, any function that is not conducive to safety, any hidden danger that will cause safety, should be eliminated in time, otherwise once the tragedy happens, it will be regretted.
