Invention patent of lightweight aluminum anti-collision beam

In the domestic new energy vehicle market, small pure electric vehicles have become the first choice for many users because of their good practicability and affordable price. With the rapid expansion of this market segment and increasingly fierce competition, various brands have come up with their own housekeeping skills. But on the whole, most manufacturers' efforts are focused on improving the face value, intelligent configuration and other places that users can see at a glance, so as to attract users' attention in the first time. Then, a car company found another way, not only focusing on the quality of vehicles, but also quietly making its own efforts. This is Chery, an independent automobile brand famous for its adherence to the technical route. Its new energy pure electric vehicle ant adopts aviation-grade all-aluminum body design, which sets a new benchmark for the market in terms of safety quality such as body strength.

The ant adopts an all-aluminum frame body, which provides enough body strength for the vehicle. In order to show our strength more intuitively, the little ant deliberately carried out a series of challenges, which made us completely jump out of those complicated parameters and concepts and make judgments based on seeing. This series of challenges not only includes the static pressure test of two container tops weighing 3.8 tons each, but also further challenges the difficult Archimedes lever principle.

Recently, the little ant has released a big move with confidence. Use two small ants+two Chery unbounded Pro*** to lift the 30-ton king of land warfare-tank. When the giant T59 tank was suspended above the small ants and unbounded Pro, the heavy oppressive feeling came to my face, making people breathless. Finally, they successfully completed the ultimate compressive challenge test of the "aluminum cabin". Ant and unbounded Pro not only have no harmful deformation in the body structure, but also successfully drive out of the test site, which makes people curious.

So, where does the super strength of small ants come from? Today, we will disassemble the "aluminum cabin" of the small ant and make a comparison with the competing models on the market. In the whole front module and front and rear cover of the vehicle, the small ant adopts PP+GF polymer composite material. Compared with ordinary steel, this material has better tensile strength and can realize "automatic recovery" for small bumps in daily use. For the traditional materials used in competing models, it is basically difficult to avoid hitting a pit. At the same time, the front longitudinal beam structure gradually collapsed by the small ant can absorb the collision energy to the maximum extent when the vehicle collides, provide sufficient buffer, reduce the possibility of deformation in the cockpit area, and provide sufficient safety guarantee for users to travel.

Next, it is the internal structure of the door of the little ant. For our users, there are generally not many opportunities to see it with their own eyes, but the internal support system of the door is really protecting our travel safety, which is called an unsung hero. From the disassembly diagram, we can clearly see that a thick aluminum alloy anti-collision beam is installed on the door of the ant, which keeps the danger out. It is conceivable that the small round tube anti-collision beam used in competing models can provide much protection in hidden corners.

Ants set aluminum alloy beams at the rear of the car, which are firmly connected with the all-aluminum body frame, which not only protects the rear drive motor at the rear of the car, but also prepares for the possible rear-end collision. The rear structure of competing models is basically undefended and will be seriously injured in the event of an accident.

Finally, let's learn the secret that small ants can bear the weight of the king of land warfare. Compared with the simple cross-sectional form of the profile of competing cars, the aluminum profile with closed cross-section adopted by Little Ant cooperates with the "Falcon-shaped multi-cavity cross-sectional structure" of the whole car, so that the whole car body structure presents a cage-like three-dimensional space, which not only reduces the weight by 30%, but also increases the rigidity of the car body by 20%, greatly improving the compression resistance and anti-collision effect of the car, which is why Little Ant dares to challenge the 30-ton tank. Up to 68.7% of 6-series aluminum alloy is used as the main structure of the body skeleton of the ant. The skeleton skin is made of 5 series aluminum alloy plates; The outer plate of the B-pillar is made of ultra-high strength steel plate reaching Usibor1500 p. The aluminum lightweight technology adopted by the ant has obvious leading advantages in the domestic market. This technology was jointly recommended by the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology and the Ministry of Natural Resources on June 5438+February 3 1 2020, which highlighted Chery's hard-core technical strength.

At present, under the fierce competition in the domestic new energy mini-car market, many competing models with high homogeneity are dazzling and have no choice. As a domestic automobile manufacturer that always pays attention to technological progress, Chery's excellent quality has been fully recognized by many consumers. The world's first all-aluminum profile structure and its unique "Falcon-shaped multi-cavity cross-section structure" launched by the manufacturer not only set a new technical benchmark in the market, but also provided more security for small ant users and truly respected life. If you are interested in getting a pure electric scooter, Chery ants with affordable price and good security will be able to accompany you throughout the journey.
