1. The weight is related to the required use:
The original intention of electric wheelchair design is to realize independent activities around the community. However, with the popularity of family cars, it is also necessary to travel and carry frequently.
The weight and size of the electric wheelchair shall be considered if it is carried out. The weight of a wheelchair is mainly determined by the frame material, battery and motor.
Generally speaking, the electric wheelchair with aluminum alloy frame and lithium battery of the same size is about 7~15 kg lighter than the electric wheel with carbon steel frame and lead-acid battery.
2. Durability:
Big brands are more reliable than small ones. Considering the long-term brand image, big brands use sufficient materials and exquisite technology. The controllers and motors they choose are relatively good. Some small brands mainly rely on price competition because of their poor brand influence. Therefore, it is inevitable to steal work and craft.
In addition, aluminum alloy is light and solid. Compared with carbon steel, it is not easy to corrode and rust, and its natural durability is relatively strong.
In addition, lithium batteries have a longer service life than lead-acid batteries. The lead-acid battery can be charged for 500~1000 times, and the lithium battery can reach 2000 times.
3. Security:
As a medical device, the safety of electric wheelchair is generally guaranteed. Are equipped with brakes and safety belts. Some also have anti roll wheels. In addition, for wheelchairs with electromagnetic braking, there is also a ramp automatic braking function.
4. Comfort:
As a device that is inconvenient for people to move for a long time, comfort is an important consideration. Including seat height, seat length, width, leg distance, driving stability and actual riding experience.
