The failures of electric wheelchairs mainly include battery failure, brake failure and tire failure.
1. Battery
Electric wheelchairs, as the name suggests, batteries are the key to driving electric wheelchairs. The battery of high-end electric wheelchairs is also relatively expensive in the market. Therefore, in the process of using electric wheelchairs, battery maintenance is very important. The problem that the battery is more prone to is that there is no way to charge it and it is not durable after charging. First, if the battery cannot be charged, check whether the charger is normal, and then check the fuse. Small problems basically appear in these two places. Secondly, the battery is not durable after charging, and the battery is also damaged during normal use. Everyone should know this; the battery life will gradually weaken over time, which is normal battery loss; if it occurs suddenly Battery life problems are generally caused by excessive discharge. Therefore, in the process of using the electric wheelchair, the battery should be diligently maintained.
2. Brake
Among the control components of an electric wheelchair, the brake is a very important part, which is closely related to the personal safety of the user. Therefore, it is important to check that the brakes are working properly every time before using an electric wheelchair. The most common cause of brake problems is the clutch and rocker. Before each trip with an electric wheelchair, check whether the clutch is in the “on gear” position, and then check whether the joystick of the controller bounces back to the middle position. If it is not for these two reasons, it is necessary to consider whether the clutch or controller is damaged. At this time, it is necessary to repair it in time. Do not use an electric wheelchair when the brakes are damaged.
3. Tires
Since the tires are in direct contact with the ground, the road conditions are different, and the wear and tear of the tires during use is also different. A common problem with tires is punctures. At this time, you need to inflate the tire first. When inflating, you must refer to the recommended tire pressure on the surface of the tire, and then pinching the tire to see if it feels firm. If it feels soft or your fingers can press in, it may be an air leak or a hole in the inner tube. The maintenance of tires is also very important. Many people find that they can’t walk in a straight line after using electric wheelchairs for a period of time. In fact, major problems occur in the tires, such as tire deformation, air leakage, looseness, etc., or the bearings at the wheel joints. Insufficient lubricating oil, rust, etc. are all possible reasons why the electric wheelchair cannot walk in a straight line.
1. Electromagnetic brake: You can brake only when it is electric! ! !
2. Tires: Always pay attention to whether the tire pressure of the tires is normal. This is the most basic.
3. Chair cover and backrest: Wash 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 do not use too much to avoid oil stains on the floor. Always maintain general maintenance and check whether the screws and screws are secure.
5. Usually, please wipe the car body with water, avoid placing the electric wheelchair in a damp place and avoid hitting the controller, especially the rocker; when transporting the electric wheelchair, please strictly protect the controller. When the beverage is contaminated, please clean it up immediately, wipe with a cloth with diluted cleaning solution, and avoid using cleaning agents such as abrasive powder or alcohol.
