In recent years, with the continuous development of the new energy wave, many car companies have developed their own new energy models. Among them, mini-cars are also one of the key areas where major car companies are gradually developing their efforts, and the safety of the mini-electric car market has always been a concern for everyone. Only when a car is safe to drive and can be driven with confidence can the driver feel at ease. And there is such a model, which relies on the safety of the "all-aluminum body" used in mid-to-high-end models of luxury brands, and it is the Chery Ant/Unbounded Pro.
Reproduction of "Archimedes' Leverage Principle Challenge"
"Give me a fulcrum and I can lift the entire earth." I believe everyone has heard this sentence from Archimedes Virtue's famous saying, this is also the famous Archimedes' principle. Earlier, Chery replicated the "Archimedes' Lever Principle Challenge" with the Little Ant model.
The principle of this challenge is to use small ants as the fulcrum of the lever and hang heavy objects on one or both sides of the lever to test the pressure-bearing capacity of the car body. This also places great demands on the body materials and structure of Little Ant.
In three rounds of tests, Little Ant accepted the challenges of 3.2 tons, 8 tons, and 5.25 tons respectively. After the three challenges, Little Ant did not find any deformation. At the same time, the roof interior still maintained intact.
Small cars also have great power!
Perhaps because they feel that the "Archimedes' Principle Challenge" is not exciting enough, Chery Automobile once again launched the "Lifting 30-ton Tank Challenge".
In this event, Little Ant and Unbounded Pro will also challenge the big BOSS, a T59 main battle tank. According to reports, this tank weighs 36 tons. Even if the reactive armor, turret facilities, gun barrel, and engine of the tank are not in original condition, the weight of this tank can reach 30 tons.
Through the on-site challenge, we learned that the test this time was to arrange 2 Chery Ants and 2 Chery Unbounded Pros in a "2X2" layout, and slowly place the T59 tanks through a crane. On the roof of four vehicles, calculated in this way, the theoretical distribution weight of each vehicle is 7.5 tons. For micro pure electric vehicles such as Little Ant and Wujie Pro, it bears a weight that it should not bear. After the test, the body structure of each heavily-pressed car remained almost intact, and all four doors could be opened and closed. It can be described as a miracle!
The secret comes from here!
So why are Little Ant and Unbounded Pro able to bear the weight of a tank?
The reason is that Ant and Wujie Pro are equipped with "aluminum cabins". Both bodies adopt an aviation-grade all-aluminum frame body design and adopt a "falcon-shaped multi-cavity cross-section structure", which can reduce the weight of the vehicle by 30% while also increasing the body stiffness by 20%! The material utilization rate has also reached 96%, and the aluminum-based body is 100% recyclable, achieving low energy consumption and high recycling!
In addition, Little Ant uses 6 series aluminum alloy in the body, accounting for 68.7% of the entire vehicle. The skin structure of the body frame is made of 5 series aluminum alloy; the outer panel of the B-pillar of the body is made of Usib or 1500P hot-formed steel plate; the front-end module and the front and rear covers are all made of polymer composite PP+GF material.
In addition to the strong rigidity of the body, the suspension has also endured a lot
In addition to the heavy pressure on the body, we can also clearly see that whether it is Little Ant or Unbounded Pro, their The suspension also endured a lot silently. After reading the information, the editor learned that both Ant and Wujie Pro adopt a MacPherson independent suspension design. Compared with the front MacPherson + rear torsion beam used by competitors, the layout is significantly larger! At the same time, the driving control and comfort are also stronger, which is especially helpful for driving safety!
Electric EV: Spending money on the word "safety", Chery has achieved "a small car with great power"!
We all know that ants are famous "strong men" in nature. In them, we know that ants can lift more than 400 times their own weight. In the automotive world, Chery Ant has also successfully proved itself to be a "strong man". Not only did it successfully challenge the 7.6-ton roof still life weight and successfully replicate the "Archimedes' Principle Challenge", it also successfully challenged the lifting of a 30-ton tank, showing amazing product performance. This shows how much effort Chery has put into the word "safety" in new energy. In the true sense, "a small car also has great power!"
