Not afraid of hitting ultra-high strength steel-aluminum hybrid car body to build the first line of defense for safety
We usually call the collision between a car and an external object a "primary collision", while the collision between an occupant and an internal part of the car is called a "secondary collision". For the occupants in the car, the risk brought by the first collision is "inertial impact", and the impact intensity brought by the second collision greatly affects the harm to the human body, so the safety and reliability of the car body structure are particularly important for protecting the occupants in the car. In the C-IASI evaluation system, the evaluation of car body structure is mainly reflected in three experiments: frontal 25% offset collision, side collision and roof strength.
The frontal 25% offset collision simulates the actual traffic accidents such as car-to-car collision, car-to-tree collision and telephone pole collision with small overlapping area. "25%" refers to the overlap ratio between the cross section of the car body and the rigid wall obstacle in frontal collision. When a vehicle collides, the smaller the frontal collision area, the greater the local force on the vehicle body, the less easily the huge impact force is dispersed, and the greater the safety threat to the occupants in the vehicle. Generally speaking, this position is located in the 25% area on both sides of the front of the car, which can be called the "cover door" of the car structure. Because of the small overlap, most of the impact force needs to be absorbed by the anti-collision beam and suspension structure. Therefore, whether its anti-collision design is firm or not affects the safety of the whole vehicle and is also an important reference factor for the safety index of a vehicle.
In the frontal 25% offset collision of China Insurance Research Institute, the polar krypton 00 1 ensures the complete occupant living space with ultra-high strength cage body structure, and the deformation of A-pillar and threshold is almost zero. Such excellent results are due to the efforts of Krypton 00 1 in car body safety. In order to build a solid safety fortress, Krypton 00 1 was developed with five-star safety standards to build a high-performance steel-aluminum hybrid lightweight body. Ultra-high-strength thermoformed steel beams with strength 3-4 times that of ordinary steel and up to 1300MPa are used in key parts such as A-pillar, B-pillar and roof frame, and are mostly used in armored vehicles. The cage structure and the reinforcement of ultra-high strength thermoformed steel make the top bearing capacity of Krypton 00 1 reach about 1 1.5 tons, which can efficiently absorb and disperse collision energy from different directions and prevent the cabin from deformation.

Krypton 00 1 also adopts the leading motor active sinking protection technology. When a collision occurs, the vehicle will take the initiative to disengage the front motor and sink to change the collision direction, so as to prevent the motor from invading the passenger compartment and further protect the safety of the passenger compartment. At the same time, the structural design of "off-wheel unloading" is adopted, which can passively cut off the high-rigidity front wheel in the collision, so that the front wheel is out of contact with the car body, which can better disperse the force generated by the collision and avoid the danger of the hub invading the passenger compartment.
Advanced structural collision strategy-engine sinking; Off-wheel unloading force
Krypton 00 1 not only has a high-performance lightweight steel-aluminum hybrid body, but also adopts the energy absorption strategy of extreme collapse. No matter the common accidents such as head-on collision, side collision, rear-end collision, or the rollover caused by the out-of-control vehicle, it can effectively prevent the deformation of the passenger compartment from causing harm to the occupants in the vehicle and strive for more living space for the occupants in the vehicle.
In order to resolve the collision energy, the high-performance steel-aluminum hybrid lightweight body is designed with seven horizontal and five vertical multi-channel stress structures, including: anti-collision beam, energy-absorbing box and longitudinal beam, subframe, wheels, lower A-pillar and threshold. Moreover, the front and rear frames of Krypton 00 1 are provided with collapse zones, which have appropriate strength and good deformability, and can fully meet the needs of lightweight car body, collision collapse unloading force and pedestrian protection. Taking the front of an automobile as an example, when a collision occurs, the energy-absorbing structure collapses and bends its tail end, which allows energy to be transmitted and released laterally while absorbing energy, effectively avoiding the risk of structural breakdown and protecting the passenger compartment and battery compartment.

Not only the frontal 25% offset collision, polar Krypton 00 1 achieved excellent results in all details of the side impact test, among which the intrusion of the side structure obtained the best performance of the car. Polar Krypton 00 1 adopts "nine-grid" anti-collision structure design, and the anti-collision beam arranged at the bottom of the side of the car body traverses the car body between the front and rear wheels. When the side of the car body collides, the total width of nine three-layer irregular cars is about 133mm, which can collapse layer by layer from the outside to the inside to cushion the collision between battery layers. The anti-collision structure of "Jiugongge" battery enables the whole vehicle to bear an instantaneous impact force of about 7 1.4 tons (700kN) when the side column collides. It is worth mentioning that in the side impact safety verification of Krypton 00 1, the safety standard consistent with Krypton 009 was adopted, and the side column impact test was carried out every 12.7cm, far exceeding the industrial requirement of 1 test point, and * * measured 15 point.
Extreme krypton 00 1 brings more comprehensive safety protection to family members than that.
To evaluate the safety of a car, we should consider both active safety and passive safety, and intelligent auxiliary safety is also very important. In this insurance research and test in China, the ZAD intelligent driver assistance system equipped with Krypton 00 1 achieved the highest score of vehicle assistance safety index 1 13.78, which is also the only vehicle assistance system with three full marks. Excellent results are attributed to the use of top-level intelligent sensing hardware and leading algorithms to prevent problems before they happen. The krypton 00 1 is equipped with dual 7nm Mobileye EyeQ5H intelligent driving chips and falcon eye Vidal Hawkeye visual fusion sensing system. Through the auxiliary driving safety function of the whole scene, we can make a safe and efficient judgment before the collision danger of the vehicle, effectively prevent and reduce the risks encountered in the driving process and improve driving safety.

The concept of global security not only pays attention to the safety of users' travel, but also considers all aspects of electricity consumption, health and information security in the era of intelligent pure electricity. In terms of the safety of the three major electrical appliances concerned by new energy users, Kykrypton 00 1 adopts NTP non-thermal diffusion prevention and control technology, and promotes the safety of batteries to a new height through six safety protection measures: real-time prevention and control, early warning, active heat dissipation, passive heat insulation, rapid exhaust and intelligent power off. At the same time, relying on the industry-leading 360 battery safety protection system, as well as 265, 438+08 system-level safety tests and 675 parts tests covering six categories of extreme working conditions, the battery pack is not afraid of collision, fire and wading, making the safety of pure trams impeccable.
The highest battery safety standard in the industry, no heat dissipation and no fire.
In terms of occupant health, Krypton 00 1 adopts hard-core protection such as CN95 air conditioning filter, App controllable intelligent active cockpit cleaning, AQS air quality detection and control system, etc., so that the air inside the car can be kept fresh at all times, and it can also be sterilized and mildewed. In addition, with the rapid development of automobile intelligence, information security has become particularly important. For this reason, Krypton 00 1 has built three "invisible firewalls", which can completely achieve zero information leakage, zero tampering and zero false alarm, and ensure the safety of automobile information.
Comfort, health and safety cockpit
Krypton 00 1 has created a number of records in the most stringent C-IASI evaluation system, set the standard for the safety model of medium and large vehicles, and fully proved the strong system strength and innovation ability of Krypton. In addition to authoritative testimony, kryptonian security always speaks with facts. In the past two years, Krypton has delivered nearly100000 products, and it still maintains the only zero-fire record of batteries in the industry. Starting from the safety of users, Krypton Space not only adheres to the safety bottom line, but also raises the safety standard of intelligent driving to a higher level. Practice has proved that safety is the biggest luxury of electric vehicles.
