Yu Chengdong once said that he copied Huawei! Xiaomi's response is to smear: the keel shaft patent is officially confirmed and there are big differences between the two parties

According to news on August 7, Xiaomi’s keel hinge hinge patent was recently approved. The application was filed on September 18, 2020, and the application was announced on March 18, 2022. The final authorization announcement date is June 25, 2024. The technology involved in this patent is the “keel hinge” that was already installed on Xiaomi MIX Fold 3.

Judging from the patent summary, the rotating shaft adopts a unique three-stage connecting rod rotating shaft design, which not only improves the freedom of the rotating shaft, but also greatly improves the reliability and anti-drop performance of the entire machine. Its folding life has reached 500,000 times.

1. Yu Chengdong laughed at the 2023 Pollen Annual Meeting and talked about plagiarism by friends, saying that he had infringed on Huawei's intellectual property rights, used Huawei's designs without authorization and changed names at will.

2. Yu Chengdong pointed out that Xiaomi renamed the double-rotating water droplet hinge as a keel hinge, and the so-called keel hinge does not actually exist.
3. Xiaomi responded that the "keel hinge" is a new generation of folding hinges developed by it. It adopts the industry's first 3-level rod structure, which improves the precision and reliability of folding quality.
4. As can be seen from the comparison patent pictures, there are differences in the hinge designs of Huawei and Xiaomi. Although both have a U-shaped (water drop-shaped) structure, Xiaomi's lower structural member is a pole, while Huawei's lower structural member is a knob.
