safety
Most of the ordinary electric wheelchairs that appear on the market now have only one controller, two motors, and four wheels. There is nothing they can do when they reach the stairs or the environment where they need to go upstairs. Many elderly people have inflexible legs and feet and cannot go up and down the stairs by themselves.
For the electric stair-climbing wheelchair, not only can it drive on flat ground, but it is also equipped with crawlers for climbing stairs, which can switch between the two functions of walking on flat ground and climbing stairs. It walks like an electric motor, and when you encounter stairs, you can put down the crawlers and climb the stairs like a small tank.
Although it seems very simple, the consideration of safety cannot be ignored. The elderly generally have weak control ability. The steep steps and narrow spaces encountered by climbing stairs are a huge safety threat to the elderly. To make a product that is very safe to use is not just as simple as adding a crawler to the electric wheelchair. It requires careful design, carefully considering the actual conditions of various steps, various usage environments, and different elderly people. Troubles and obstacles that may be encountered during operation.
Moreover, it also needs to be easy to operate and there is no safety risk during operation. It often takes several years of design, development and testing to produce a final mature and reliable electric stair climbing wheelchair.
In the past few years, it is not uncommon for the elderly to slip up and down the stairs and fall, which also shows the demand and safety requirements of the elderly for electric stair-climbing wheelchairs.
The standard is very high! The design of ordinary electric wheelchairs does not need to consider these issues, only the basic safety issues of speed and braking need to be considered, which is much simpler.
Low Yield
Ordinary electric wheelchairs or electric vehicles have a relatively mature industrial chain, especially ordinary electric vehicles, with an annual production volume of tens of millions of units in China. In addition to the number of exports, it can basically exceed 100 million per year. Such a huge output The volume of goods also makes the entire industrial chain very mature. From parts to OEMs, the production cost is extremely low, and the terminal sales price is also relatively low.
Even for ordinary electric wheelchairs, with the years of market development and the increase of the elderly population in the country, the industrial chain has gradually improved, and the annual shipments are close to 10 million units. The output value is tens of billions, which also makes the cost drop a lot. However, there are only a handful of manufacturers in the field of electric stair climbing wheelchairs in the world, no more than 100, and most of them are only engaged in electric stair climbing wheelchairs, and generally have other main businesses to produce other products. The annual production of electric stair-climbing wheelchairs in China is only tens of thousands, which belongs to the output
For an extremely low industry, due to the low overall output, the supporting industrial chain will not be particularly mature, so that the cost of accessories, production, operation, maintenance and other links will increase accordingly, resulting in the terminal retail price of the electric stair climbing wheelchair. Not low, which is one of the important reasons.
