The difference between electric ladder wheelchair and traditional wheelchair

Difference 1: Security

Most common electric wheelchairs currently on the market have only one controller, two motors and four wheels. Although they can be driven by electric motors on the ground and can facilitate the elderly to travel, they cannot climb stairs. When they encounter stairs or need to go upstairs, they can do nothing. Many elderly people have inflexible legs and feet and cannot go up and down stairs alone. Even if they go up and down stairs, they have no power to move dozens of kilograms of electric wheelchairs up the stairs.

The electric ladder wheelchair can not only be driven on flat ground, but can also be equipped with crawler tracks. It can switch between two functions: walking on the ground and climbing stairs. When you need to walk on the flat ground, you can fold it and move like an electric motor. When you encounter a staircase, you can put down the crawler and climb the stairs like a small tank.

Although it seems simple, safety considerations cannot be ignored. The general control ability of the elderly is relatively weak. The steep steps and narrow spaces encountered when climbing stairs are a huge safety hazard for the elderly. To make a very safe product, not only to simply add a track on the basis of an electric wheelchair, but also need to be carefully designed, carefully consider the actual situation of the various use environments of each step, and different elderly people may The troubles and obstacles encountered. In addition, it needs to be easy to operate without security risks. It often takes several years of design, development and testing to produce the ultimate mature and reliable electric climbing wheelchair.

In recent years, it is not uncommon for elderly people to slip up and down stairs. This also shows that the demand for electric ladder wheelchairs and the safety requirements of the elderly are very high! The design of ordinary electric wheelchairs does not need to consider these issues, only need to consider the basic safety of speed and braking, which is much simpler.

Difference 2: Low output

The industrial chain of ordinary electric wheelchairs or electric vehicles is relatively mature, especially ordinary electric vehicles. China's annual output is often tens of millions of units. Adding the export volume, the annual output is basically over 100 million. Such huge trading volume also makes the entire industry chain very mature. From accessories to OEMs, production costs are extremely low, and terminal sales prices are relatively low.

Even for ordinary electric wheelchairs, with the development of the Chinese market for many years and the increase in the elderly population, the industry chain is gradually improving. The annual shipment is close to 10 million units, and the output value is several billions, which also makes the cost drop a lot. However, at present, there are only a few manufacturers in the field of electric climbing wheelchairs, no more than 100. Most of them are only engaged in electric climbing wheelchairs. Generally speaking, they have other major businesses to produce other products. China's annual output of electric climbing wheelchairs is tens of thousands, which belongs to an industry with extremely low output. As the overall output is low, the supporting industrial chain will not be particularly mature, so that the costs of parts, production, operation, maintenance and other links will increase accordingly, resulting in the retail price of electric climbing wheelchair terminals is not low, which is one of the important reasons.
