1. One ratio controller
The types of electric wheelchair controllers can be divided into manual control, head control, tongue control, cheek control, chin control, air control, voice control, etc. Except for manual control, other controls are used for patients with quadriplegia. Whether an electric wheelchair is good or not depends on the performance of the controller, because the controller instantly controls the wheelchair to move in any direction (360 degrees), which is the nerve of the wheelchair. The controller is divided into domestic controller and imported controller. Generally, the price of electric wheelchairs with domestic controllers is below 7,000 yuan and above 5,000 yuan; the prices of electric wheelchairs with imported controllers are relatively high, basically ranging from 7,000 to 10,000 yuan.
2. Second ratio motor
Because the motor is the main driving power part of the electric wheelchair, it is also the heart of the electric wheelchair. At present, there are mainly two types of brush motors (high-speed and low-speed) and brushless motors in China.
The brushed low-speed motor has a larger current and weaker performance when starting and climbing; the brushed high-speed motor has good wear resistance and reasonable design, which effectively reduces the maintenance cost of the electric wheelchair. As my country stipulates that electric bicycles and electric wheelchairs are non-motorized vehicles, and the speed of brushless motors is above 20 km/h, they are not used.
3. Three ratios of material
How to buy an electric wheelchair?
The materials of electric wheelchairs can be divided into aluminum alloy and steel tube materials. Now the aluminum alloy used for electric wheelchairs is made of high-strength aluminum alloy. This material not only has the advantages of steel pipe’s sturdiness and durability, but also light weight, avoiding the disadvantage of heavy steel pipe material.
4. Four choice brands
Electric wheelchairs are more elaborate than ordinary wheelchairs, so the requirements on the manufacturing process are relatively high. It is recommended to choose an electric wheelchair brand.
2. Safe use and careful maintenance
Safe use steps: Raise the foot pedal, and then put the foot pedal down after the user is seated; make sure that the arm can freely control the rocker, and make sure that the seat is adjusted to the proper position.
The maintenance of electric wheelchairs should pay attention to the following issues:
1. Manual brake (safety device): always check whether the manual brake is adjusted normally. Pay attention to whether the wheels are completely stationary when using the manual brake, and tighten all the screws and screws.
2. Tires: Always pay attention to whether the tire pressure is normal. This is basic.
3. Chair cover and backrest: Clean the chair cover and leather backrest with warm water and diluted soapy water.
4. Lubrication and general maintenance: Always use lubricant to maintain the wheelchair, but don’t use too much to prevent oil stains on the floor. Maintain general maintenance from time to time, and check whether the screws and screws are secure.
5. Usually, please wipe the body of the car with clean water, avoid placing the electric wheelchair in a damp place and avoid hitting the controller, especially the rocker; when carrying the electric wheelchair, please protect the controller strictly. When the controller is exposed to food or When the beverage is contaminated, please clean it up immediately, wipe it with a cloth dampened with a diluted cleaning solution, and avoid using detergents containing powder or alcohol.
