"The hatchback is not safe, and it will be finished as soon as it is rear-ended."

"The lighter the car, the less it will hit."

"The safety of the car is poor and it is not strong at all."

Is that really the case? Mini and small pure electric vehicles, which are popular on the market now, all carry a big battery. Will it be more unsafe? In fact, the safety of the vehicle is not directly related to the positioning of the vehicle type and the size of the car body. As long as we are willing to make "hard materials" and attach importance to the safety design of the car body, the lower safety limit will not be low. The only problem is that this will lead to a substantial increase in the cost of building a car, which is obviously unrealistic for miniature pure electric vehicles with generally low prices.

But among them, there are also some "heterogeneous", such as Chery Automobile. Both small ants and unbounded Pro have the ultimate pursuit of their own safety. Moreover, Chery seems to be a masochist. The ant has completed the static pressure test of the 7.6-ton roof, repeating the Archimedes lever principle challenge. That's not all. The ultimate compressive challenge of Chery ant "aluminum cabin" continues. Can this "lifting 30 tons of tanks" succeed?

Chery Ant: 30-ton tank, carry it!

What kind of scene will the tank face the car? Previously, a military column of CCTV had done such an experiment. The car was crushed by the main battle tank, just like tissue paper. It is hard to imagine that mini pure electric vehicles like Chery Ant and Infinite Pro can withstand the pressure of a T59 main battle tank.

You know, T59 main battle tank is a real medium-sized tank with a total combat weight of 36 tons. Even though the reaction armor, turret facilities, barrel and engine of this T59 tank are not original, its weight has reached 30 tons.

With two Chery ants and two Chery unbounded Pro in place, the T59 was slowly moved to the top of the four cars by crane. From the pictures at the scene, we can see how strong the visual impact of T59 tank is. Chery ant and unbounded Pro are both "petite" in front of the main battle tank.

When this T59 tank fell, the weight of 30 tons was firmly pressed on the roofs of four "cars", and the theoretical distribution weight of each car was 30/4 tons =7.5 tons. This weight is not a problem for small ants who successfully challenge the static pressure test of the 7.6-ton container top cover. Unbounded Pro has also stood the test. Like the little ants, the four models have maintained a complete body structure, and the doors can be opened and closed normally.

Why can small ants and unbounded Pro constantly complete all kinds of "abnormal" safety testing challenges? Don't worry! Then look down.

Can hold tanks! The secret of ant/unbounded Pro is here.

Chery Ant and Infinite Pro both adopt aluminum frame, and its unique falcon bone multi-cavity cross-section structure can reduce the weight of the whole vehicle by 30% and improve the stiffness by 20%.

At the same time, 6 series aluminum alloy accounts for 68.7% of the body structure of Chery Ant. This kind of material is mostly found in the fuselage frame, girder and landing gear strut of aircraft, and it is definitely a solid aviation grade material. The skin structure of the car body frame is also made of 5 series aluminum alloy plates, with the help of Usibor 1500P thermoformed steel plates and PP+GF polymer composites, the torsional stiffness of Chery Ant reaches 26,967 nm/.

In addition, most mini-cars or small cars on the market at present adopt the "scooter suspension" with the front McPherson rear torsion beam. Although the cost of building a car is reduced, the handling safety and comfort will also be reduced. Chery Ant adopts a unique four-wheel independent suspension at the same level. The front and rear McPherson independent suspensions have the characteristics of strong maneuverability and comfortable driving experience, which is of great significance to driving safety.

Che Shu concluded

Chery Ant regards the ultimate compressive challenge of "aluminum cabin" and has completed three extremely severe challenges, from the static pressure test of the 7.6-ton roof, to the re-carving of Archimedes lever principle, and then to the lifting of 30-ton tanks. With the "bloodline" of safety design, both Chery Ant and Boundless Pro have reached the ceiling of safety experience in the same level. Next, what breakthroughs will Chery Ant and Unbounded Pro achieve? We will wait and see!
