AI Technical Summary
Existing hinge dampers are difficult to seal effectively and completely when sealing silicone oil. External air can easily seep in, accelerating silicone oil oxidation and affecting performance stability. Furthermore, silicone oil is prone to performance fluctuations due to displacement and shaking during operation.
A vacuum module is used to evacuate the inside of the buffer through a sealing component and an industrial vacuum pump, reducing the oxygen content. After evacuation, an oil core is pushed in to form a physical barrier, preventing external air from seeping in and ensuring uniform distribution and stability of the silicone oil.
The filling density and uniformity of silicone oil are improved, ensuring the consistency and reliability of the buffer performance, avoiding performance fluctuations caused by external impacts, and realizing stable operation of the buffer under different working conditions.
