Distinction 1: Security
Most of the ordinary electric wheelchairs appearing in the market now have only one controller, two motors and four wheels. Although they are electrically operated and can be driven on a flat ground, they can facilitate the travel of the elderly, but they can not climb stairs. When they meet the steps or need to go upstairs, they are powerless. Many elderly people do not have legs or feet. Flexible, unable to go up and down stairs by oneself, even if it can go up and down stairs, powerful can not move dozens of kilograms of electric wheelchairs up and down stairs.
For the electric climbing wheelchair, it can not only run on the flat ground, but also equipped with the track for climbing stairs. It can transform between the functions of walking on the flat ground and climbing stairs. When it needs to walk on the flat ground, it can walk like an electric one when it takes up the track, and when it encounters the stairs, it can put down the track like a small flat. Climb the stairs like gram.
Although seemingly simple, safety considerations can not be ignored. Old people generally have weak control ability. The steep steps and narrow space encountered by climbing stairs are huge potential security threats for the elderly. To make a very safe product, it is not only on the basis of electric wheelchairs, but also on the basis of electric wheelchairs. Adding a crawler is so simple that it needs careful design, careful consideration of the actual situation of various steps and various use environments, as well as the difficulties and obstacles that different elderly people may encounter in the operation process. Moreover, it needs easy operation and no safety risk in operation. It often takes several years of design, development and testing to produce a mature and reliable electric climbing wheelchair.
In recent years, it is common for the elderly to slip up and down stairs and fall down. It also shows from the side that the elderly need for electric climbing wheelchairs and the safety requirements are very high! ___________ The design of ordinary electric wheelchairs does not need to consider these issues, just need to consider the speed and brake basic safety issues, it is much simpler.
Difference 2: Low yield
Ordinary electric wheelchairs or electric vehicles, the industrial chain is relatively mature, especially ordinary electric vehicles, in China, the annual production of tens of millions of units, coupled with the export volume, basically more than 100 million a year, such a huge volume of shipments, but also let the entire industrial chain is very mature, from accessories to the whole car factory, production costs. Very low, but also let the terminal sales price is relatively low.
Even ordinary electric wheelchairs, with the development of the market for many years and the increase of the elderly population in China, have gradually improved the industrial chain. The annual shipment volume is close to tens of millions of units, and the output value is billions of dollars, which also makes the cost drop a lot. However, there are only a few manufacturers in the field of electric climbing wheelchairs in the world, no more than 100. Most of them are only engaged in electric climbing wheelchairs concurrently. Generally, they have other main business to produce other products. The annual production of electric climbing wheelchairs in China is tens of thousands, which belongs to the industry with very low output. Because of the low overall output, the matching industry chain will not be particularly mature, so the cost of accessories, production, operation, maintenance and other links will increase accordingly, resulting in the terminal retail price of electric climbing wheelchair is not low, which is also one of the important reasons.
