CQBA Magnesium Aluminum Manufacturing Co., Ltd. has won the favor of many electric vehicle manufacturers for its innovative achievements in high-strength, lightweight and shock-resistant magnesium alloy car seat frames.
Lightweight Magnesium alloy seat for EV
"The car seat skeleton is the basis of car seats. Can the seat be safe and reliable, have sufficient strength, stiffness and durability, have a compact structure and reduce mass as much as possible, mainly based on the 'skeleton'." CQBA magnesium aluminum Cha Jianshuang, deputy general manager of technology, said.
In order to successfully develop a lightweight, high-strength, shock-resistant magnesium alloy seat frame in a short period of time, since 2016, the research and development team has actively invested in research and development. After fully studying the characteristics of magnesium alloy materials and a comprehensive understanding of the structure of seat products, this magnesium alloy car seat skeleton has finally appeared.
"First of all, the technology has significantly improved overall stiffness." Zha Jianshuang introduced that the modal value of the traditional steel skeleton is only 18Hz, while the modal value of the magnesium alloy seat skeleton can reach more than 30Hz, making the NVH of the interior of the vehicle 40% performance improvement. In addition, the shock absorption characteristics of magnesium alloys have greatly improved the comfort of seats. The dynamic and static strength of magnesium alloy seat frames can meet the requirements of domestic and foreign vehicle seats.
Not only that, the integrated design of the magnesium alloy seat frame reduces the number of parts by 50%, reduces the manufacturing cycle, and reduces the risk of the manufacturing process.
Can such an innovative product withstand the test of reality?
The answer is yes. Zhan Jianshuang told reporters that the product has completed relevant test verifications according to the crash requirements of "Ford Motor" , and the test results are all qualified.
"The magnesium alloy seat frame can meet the fatigue of 300,000 times, far exceeding the customer's standard of 200,000 times." Zha Jianshuang said.
Leading high-quality development of enterprises
With the official mass production of magnesium alloy seat frames, its economic and social benefits have become more apparent.
According to Cha Jianshuang, it is precisely because the integrated design of the product can reduce the number of parts by 50%, thereby reducing the manufacturing cycle, reducing the risk of the manufacturing process and the consumption of production energy, coupled with the fewer manufacturing processes, a relatively significant reduction It not only reduces the cost for automobile manufacturers, but also reduces the waste of resources and environmental pollution during processing, and achieves better energy conservation and emission reduction effects.
"For example, a set of seats on the same platform model can be more than 4kg lighter than the original design steel frame, which greatly reduces the weight of the entire vehicle." Zha Jianshuang said, using a magnesium alloy seat frame, an economical car can reduce fuel consumption by about 16 liters, which means that a large city with millions and more cars can reduce fuel consumption by 16 million liters a year.
At present, magnesium alloy seat frame has applied for and obtained 3 patents. This technology has a domestic leading advantage and huge market potential. It has been included in the company's key business growth plan during the "13th Five-Year Plan" period. Favored by domestic automobile manufacturing companies such as automobiles and Changan New Energy Vehicles, they have reached cooperation agreements with Boao Magnesium Aluminum, and magnesium alloy seat frames will be used in more and more automobiles.
"The application of magnesium alloys in automobile seats has realized the feasibility of applying magnesium alloys to automobile parts." Cha Jianshuang said that the research and development results provided a lightweight reference direction and examples of magnesium alloy applications for the same industry. It provides a reference for more products to apply magnesium alloy materials, and also promotes the development of the magnesium alloy industry chain to a certain extent. In the future, Boao Magnesium Aluminum will continue to be committed to the development of magnesium alloy technology, further increase the ability of new product research and development, application innovation, and research results to be transformed into engineering technology, lead the high-quality development of enterprises, and contribute to the development and application of magnesium alloy industry More contributions.
