AI Technical Summary

Problems solved by technology

[0005] 1. Due to the crawler type, the rotation radius is large, and the stairs of ordinary residential buildings in China are narrow, and the stair climbing chair cannot rotate;

[0006] 2. Due to the crawler type, the stair climbing chair is easy to damage the edge of the stairs during the process of walking, especially the wooden stairs are more destructive;

[0007] 3. There is no similar product in China, and it needs to be imported, which is expensive. The price of each stair climbing machine is between 40,000 and 160,000 yuan, which exceeds the purchasing power of ordinary consumers;

[0008] 4. Since it is imported, maintenance has become a big problem, and spare parts cannot be solved, so they need to be imported from abroad

[0009] Germany and Italy also have similar stair climbing machines, mainly two-wheeled stair climbing machines, but the biggest disadvantage of this kind of stair climbing machines is that they are very bumpy and vibrate, which is a great threat to the heart of the elderly or disabled
