In today's rapid development of science and technology, new energy vehicles have gradually opened up the market, and more and more products of the new era such as "intelligent cockpit" and "black technology" have emerged on the market, and have received the favor of many consumers. While we choose a car as a means of transportation, we can not only consider whether it is smart enough, but more importantly, safety.
As a pure electric model for urban commuting under Chery New Energy, Chery Little Ant has eliminated safety anxiety for consumers through multiple experimental test challenges. Previously, after successfully challenging the roof static pressure test of two 3.8-ton containers totaling 7.6 tons, Chery Little Ant conducted the "Reproduction Archimedes Leverage Principle Challenge" for the purpose of "Aluminum Cabin Extreme Compression Challenge", including two rounds of labor-saving levers, one round of equal-force lever challenge, and finally successfully completed three rounds of leverage challenge.
Recently, Chery Little Ant's extreme pressure challenge is even more "exaggerated", and it actually "lifts a 30-ton tank to the top". At the challenge site, 2 Chery Little Ants and 2 Chery Unbounded Pro tail to tail, arranged in the form of "Tian Zi Grid", and then a tank was placed on the roof of the four cars by the crane, as can be seen from the video, in addition to the suspension of the 4 cars all to the end, the tire top to the upper wheel eyebrow, the whole vehicle structure of the four small cars has not changed much, the doors can be opened and closed normally, the tank lift is successfully completed, and the end can be driven normally.
It should be understood that the tank used in this challenge is the T59 tank, although it is not a model in service, but the armor, turret, barrel and engine are also there, weighing 30 tons. In other words, the average roof weight of 7.5 tons per trolley is achieved, how exactly is this done?
First of all, by disassembling the Chery little ant appearance cover, we can find that each cover piece is very light and can be moved by one person. By checking the materials of the front and rear surrounds, cabin covers, front fenders on both sides, door panels, rear foils and rear tailgates, we learned that they are all polymer composite materials developed by Chery, so they feel light.
Dismantling the exterior cover parts of the steel structure models of the same class, we found that in addition to the plastic parts used in the front and rear surrounds, the rest of the cabin cover, front and rear wings, and rear tailgate are all made of homogeneous thin steel plates.
As micro electric vehicles, Chery Little Ant and Unbounded Pro can complete such an "exaggerated" challenge, thanks to the fact that the body material adopts the unique Hayabusa-shaped multi-cavity section structure of the aviation-grade all-aluminum body. This design not only reduces the weight of the body by 30%, but also increases the rigidity of the body by 20%. The main structure of the body skeleton adopts 6 series aluminum alloy, accounting for 68.7%. The body frame skin structure is made of 5 series aluminum alloy. Coupled with the application of hot-stamped steel plate of the outer plate of the B-pillar, the torsional rigidity of Chery Little Ant's body reaches 26967Nm/°.
Secondly, in the front part of Chery Little Ant, a very wide anti-collision beam and hexagonal radiator frame are used, although the lightweight treatment is done, the overall structure is made of solid materials, and the arms extended on both sides are connected to the car body, which can effectively increase the ability of the car body to resist damage. The side and rear materials and structural design of the body are also in line with mainstream SUV models, and they all have high strength.
The steel structure of the same class, its anti-collision column adopts the most conventional structural design, and the size is not as wide as Chery's little ant. The side and rear steel plates are relatively thin, and the ability to resist impact is self-evident.
In addition to the safety level, the overall product performance of Little Ant and Unbounded Pro is remarkable. Although Chery Little Ant is a small family scooter, in addition to the all-aluminum body, it is also equipped with four-wheel independent suspension and rear-drive system, as well as ABS anti-lock braking system, ESC electronic stability system, tire pressure detection system and uphill assist system, and the overall driving safety and handling performance are extremely advantageous in the same class.
summary
Chery Little Ant, as a miniature pure electric vehicle priced at 6.9999-99999 thousand yuan, has not only achieved its own excellent results in safety, but also made the best proof for domestic brands with many challenges such as "replicating Archimedes lever principle challenge" and "lifting 30-ton tank topping"!
