Geely L380 sets a precedent, showing its 'iron shield skill' in a rear-end collision test with four rows of seats

With the rapid development of the automobile industry, the need to ensure the safety of passengers has become increasingly prominent. Frontal collisions and rear-end collisions have become the most important types of accidents that threaten road traffic safety, accounting for 72% of accidents. Based on this, Geely Automobile has decided to test the safety of the vehicle through rigorous front and rear impact tests before the world's first four-row pure electric high-end MPV, LEVC L380, is launched to effectively protect users' travel safety.

On January 9, the L380, known as the "Land Airbus", completed a public frontal collision test. All 31 inspections passed the comprehensive verification of passive safety and electrical safety capabilities, becoming the industry leader. The first pure electric MPV model to complete public frontal crash testing.

On April 9, the safety breakthrough of L380 continued to deepen. L380 successfully completed the rear-impact internal test challenge at the Geely Automobile Safety Technology Laboratory, passing all 20 inspection points, fully demonstrating its strong strength in rear safety. So far, the L380 has proven its industry-leading hard-core vehicle safety capabilities with "both front and rear" results. With "Airbus-level" safety standards, it has once again refreshed people's understanding of the safety performance of high-end pure electric MPVs.

The first time in the industry that four rows of seats come with dummies for rear-end collision detection

Among all types of traffic accidents, vehicle rear-end collisions are extremely common. Especially on highways, the proportion of rear-end collision accidents reaches 77.2%. Therefore, as the world's first four-row pure electric high-end MPV, the tail impact test of the L380 is of great significance to both user safety and the pure electric MPV industry.

This rear collision test uses GB 20072 as the crash test condition. The speed difference between the front and rear vehicles is 50km/h, covering almost all rear-end collision scenarios in reality. The bullet vehicle in the test condition weighs 1100kg and is non-collapseable rigidity. For the vehicle, all the energy after the collision is absorbed by the car being rear-ended; two dummies are added in the fourth row, and additional inspection contents such as electrical safety and cockpit structural safety are added. The high standard of collision design means that the L380 with a 4-row seat layout will encounter huge impact loads, which undoubtedly poses a more severe challenge to its structural stability and energy absorption capabilities.

Judging from the results of the internal test, the L380 crash performed well and passed all 20 real-time inspection items. During the test, the L380 tail quickly collapsed and deformed, fully absorbing the energy. The entire D-pillar did not bend or deform significantly. The collapse and energy absorption process was completed in the trunk part. The passenger compartment had no obvious deformation, and the dummy maintained a good posture. And there is no contact with objects in the car. This means that in the event of a real rear-end collision, even the passengers sitting in the fourth row will be fully protected, thereby greatly reducing the possibility of injury.

During the tail impact test, the L380's double flashes were triggered normally, the door lock was unlocked normally, the door handle automatically popped up, the seat belt was tightened instantly, and the RCW function (rear collision warning function) and E-call function were triggered normally , while further enhancing vehicle safety, it also provides users with more superior escape conditions. L380 also performs well in terms of electrical safety, which is crucial for pure electric vehicles. After the collision, the L380 high voltage was powered off normally, which fully complied with the three-electric safety requirements of pure electric vehicles and further improved the safety of the entire vehicle.

Three lines of defense create the L380’s safety iron shield function

As a pure electric MPV with four rows of seats, L380’s energy absorption efficiency in structural collisions and accuracy requirements are more stringent. Relying on the active and passive safety systems, L380 has created three hard-core protection lines, creating an iron shield of safety, allowing users to drive without worries, and successfully achieved the "Airbus-level safety" standard.

L380 has hard-core supports that can withstand huge collision energy. Its rear anti-collision beam made of high-strength steel has an effective coverage width of 1450mm, accounting for 72.5% of the vehicle width ratio. The "wide-area force" can effectively resist collisions and intrusions from various angles, improving protection in all aspects; at the same time, the L380 energy-absorbing box , rear longitudinal beams, and seat pit reinforcement plates form a 2 in 2 force transmission structure, which gradient supports and absorbs most of the collision energy during rear-end collisions. The 1500MPa hot-formed steel longitudinal beams ensure zero intrusion into the core area of ​​electrical safety; in addition, energy absorption The box and rear longitudinal beam are two-level unloaders, and the seat reinforcement plate constitutes a three-level reinforcement. "Sequential guidance" gradually resolves the collision energy to ensure that the energy is transmitted according to the designed path, while accurately controlling the collapse of the structure to prevent the upward displacement of the collapsed structure. , invading the cockpit. In addition, the head height of the four rows of L380 is 1582mm from the ground. Important parts such as the heads of the four rows of passengers are far away from the collision deformation zone. In the event of an accident, the "dislocation avoidance" high sitting position can provide additional survival space.

On top of the "hard core", L380 also has a "smart mind" - intelligent protection. The L380 uses the RCW function to intelligently warn the following vehicle to brake and maintain the brakes of the own vehicle to avoid secondary risks and reduce collision losses; in terms of emergency calls, the L380 will automatically trigger the E-call function when an unexpected collision occurs, calling for rescue in time and preempting rescue. Prime time; in addition, the important safety-related high and low voltage components of the L380 are placed between the front and rear axles, which can minimize the risk of damage in front and rear collisions. The high and low voltage components are placed in the middle to keep the "electricity" away from the collision. ; In the event of a collision, L380 cuts off the high voltage in milliseconds, while the 40Ah low-voltage lithium iron phosphate battery continues to provide power, ensuring that the vehicle is unlocked smoothly and that "power" is available.

In terms of the restraint system, the L380 seat guide rail adopts a high-strength seat slide rail adjustment design. The slide rail locking failure strength reaches 3 to 6.5 times the design standard, ensuring the stability and safety of the seat in extreme situations. safety. Even in the event of a low-probability event such as a collision during the adjustment process, the L380's seat can still remain strongly locked. Even when the four rows of seats are loaded with extreme luggage, the L380 can effectively prevent luggage from damaging the seat frame, thereby maximizing driver safety.

No safety, no luxury. The confidence behind “Airbus-level safety”
