Today, Ningde Times held a press conference on new chassis products in Shanghai and released the rock chassis.
This chassis is the flagship version of CIIC ultra-high safety, with the ultra-high safety performance of no fire and no explosion in the 120km/h frontal collision in the case of live charge.
The rock chassis takes electricity as the center, focuses on intelligence and safety, and is positioned as an efficient and safe base.
Before that, it has completed the winter test of Heihe River and the summer test of Turpan, with a range of more than 1000 kilometers.
, an innovative design that theoretically allows automakers to quickly assemble a vehicle simply by installing a body shell.
Rock chassis, as a set of CIIC integrated intelligent chassis with power as the core, not only emphasizes intelligence, but also puts safety performance in the first place, and is committed to creating an efficient and stable underlying architecture.
By optimizing the structural design, the system significantly improves the safety factor of the vehicle.
The model based on the rock chassis shows excellent energy absorption capacity in the crash test.
According to the data, only 15% of the collision energy is borne by the body part, while the remaining 85% is effectively absorbed by the stronger CIIC chassis.
In the actual measurement of China Automobile Research Institute, the test car equipped with the chassis crashed head-on at the speed of 120km/h, which can avoid fire and explosion.
, the 120km/h front column impact test was also carried out in the Ningde era, and the bearing area of the column impact was only 1 / 6 of that of the front impact, and the collision damage was more serious at the same speed.
At the speed of 120km/h, the impact pressure per unit area is 21 times that of 56km/h.
In the experiment, the trial-made cars with the chassis successfully passed the 120km/h front column impact test, and the high voltage was powered off at the moment of collision, and there was no fire or explosion after 12 hours of rest.
The rock chassis adopts a three-dimensional bionic tortoise shell structure, which integrates the car body and the energy cabin.
the aircraft carrier barrier structure can decelerate the vehicle step by step and reduce the invasion speed.
submarine grade thermoformed steel and aerospace grade aluminum alloy can improve the chassis support strength.
The reason for the research and development of rock chassis in Ningde era is out of a deep insight into the current automobile safety situation.
In recent years, with the frequent occurrence of automobile safety accidents, authoritative data reveal the sharp increase in the number of traffic accidents and the shocking number of casualties.
There were more than 157000 traffic accidents nationwide in 2022, and by 2023, the number had climbed to 255000.
In the face of such a grim situation, safety has become the primary issue of the automobile industry.
, the rapid development of the new energy vehicle industry has also brought new challenges.
Although the production and sales of new energy vehicles continue to grow, the problem of spontaneous combustion has become a bottleneck restricting its development.
In the first half of this year, there were 150 accidents of spontaneous combustion of new energy vehicles, an increase of 20% over the same period last year.
In order to meet these challenges, Ningde era put forward a solution to evolve from single cell safety to integrated intelligent chassis system security.
Due to reducing the development cycle and time of chassis components, it can help the mainframe factory to reduce the related development time, and finally help the vehicle development cycle to be controlled in 12-14 months, thus faster to lay out the product to market.
In addition, Ningde Times also signed an agreement with Avita at the press conference.
Avita will become the first new energy brand in the world to adopt the rock chassis of Ningde era.
Chen Zhuo, president of Avita Technology, stressed this initial cooperation at the press conference.
, Ningde Times aims to sell the rock chassis to top automakers seeking to accelerate research and development and reduce costs.
For Zeng Yuqun, chairman of the Ningde era, the emergence of the rock chassis helps to promote further growth in the Ningde era.
Zeng Yuqun told Reuters in November that the Rock chassis plan could reduce the cost of developing new electric cars from tens of billions of dollars to nearly $10 million, and allow minority electric car companies to make a profit by selling only 10, 000 cars a year.
