How often should the brake system of an electric wheelchair be checked?

1. Introduction
Electric wheelchairs have brought great convenience to people with limited mobility, allowing them to travel and participate in social activities more freely. As one of the key safety components of electric wheelchairs, the performance of the brake system is directly related to the safety of the user. Therefore, it is very important to regularly check the brake system of electric wheelchairs. Next, we will explore the inspection cycle and related details of the brake system of electric wheelchairs.

2. The importance of the brake system of electric wheelchairs
Ensure user safety: The brake system can brake the electric wheelchair in a timely and stable manner when it needs to stop, prevent accidents such as collisions and falls caused by failure to brake in time, and ensure the personal safety of the user.
Maintain wheelchair stability: Under special road conditions such as slopes, a good brake system can prevent the electric wheelchair from accidentally sliding, keep it stable, and provide users with reliable support and a stable riding experience.

3. Factors affecting the inspection cycle of the brake system
Frequency of use: If the electric wheelchair is used for a long time every day, and is frequently started and braked, the wear rate of the components of the brake system will accelerate, so the inspection cycle needs to be shortened. For example, if an electric wheelchair is used for more than 8 hours a day, a detailed inspection of the brake system may be required every quarter.
Usage environment: When using an electric wheelchair in complex road conditions, such as bumpy roads, places with many slopes, or in bad weather conditions, the brake system is burdened and the inspection cycle should be shortened accordingly. For electric wheelchairs that often travel outdoors in mountainous areas, the brake system may need to be inspected once a month.
User weight: When the user is heavier, the pressure and wear on the electric wheelchair brake system will also be greater. To ensure safety, the inspection frequency should be increased.

4. Regular inspection cycle of electric wheelchair brake system
Daily quick inspection: Before each use, the user or caregiver should conduct a simple quick inspection, including observing whether the brake pads are obviously damaged, whether the brake line is loose, and whether the brake operation is smooth, etc. This can timely discover some obvious problems and avoid traveling with faults.
Regular in-depth inspection: It is generally recommended to conduct a comprehensive in-depth inspection of the electric wheelchair brake system every 3-6 months. Professional maintenance personnel will use professional tools to conduct detailed inspections on various components of the brake system, such as measuring the thickness of the brake pads, detecting the wear of the brake discs, testing the braking force and response time of the brakes, etc., to comprehensively evaluate the performance and status of the brake system and ensure its safety and reliability.

5. Inspection focus and cycle of different brake components
Brake pads: Brake pads are the core wear parts of the brake system. Usually, their wear degree should be carefully checked every 3-6 months. When the brake pads are worn to a certain extent, the braking effect will be significantly reduced. Generally, the wear limit mark of the brake pads is about 2-3mm. When this limit is reached, it needs to be replaced in time, otherwise it will affect the braking safety.
Brake discs: The inspection cycle of the brake discs can be appropriately longer, generally every 6-12 months. Mainly check whether there are scratches, cracks, deformations and other problems on the surface of the brake discs. These problems may affect the stability of braking and the transmission of braking force. If there is serious damage, it also needs to be replaced in time.
Brake line and brake oil pipe: For electric wheelchairs equipped with mechanical brakes, the brake line should be checked once a month for looseness and broken wires; the brake oil pipe should pay attention to whether it is aging, cracking, oil leakage, etc., and is generally checked every 3-6 months to ensure that the braking command can be transmitted accurately.
Brake motor and controller: The brake motor and controller are the core components of the electric wheelchair braking system. They need to be fully tested by professionals every six months to one year to check whether their internal circuits are normal, whether the brake signal response is sensitive, and whether the brake force output is stable, etc., to ensure the overall performance of the brake system.

6. Professional equipment and methods for braking system inspection
Braking force tester: The braking force tester can accurately measure the braking force of the electric wheelchair at different speeds and loads, and determine whether the braking force meets the relevant standard requirements. During the test, fix the wheelchair on the test platform, simulate various actual driving conditions, start the braking force tester, record the braking force data and analyze it.
Braking distance test equipment: Using professional braking distance test equipment, the distance from the start of braking to the complete stop of the electric wheelchair can be measured at the specified speed and road conditions to evaluate whether the braking effect meets the standard. The test should be carried out in accordance with the standard test methods and procedures to ensure the accuracy and reliability of the test results.
Wear detection tools: such as measuring tools, calipers, etc., are used to measure the degree of wear of components such as brake pads and brake discs, and compare them with the standard size to determine whether they need to be replaced. During the inspection, the dimensions of each key part should be accurately measured, and no minor wear problems should be missed.

7. How to perform maintenance and care according to the inspection results
Replace worn parts in time: If the inspection finds that the brake pads, brake discs and other components are severely worn and meet the replacement standards, they should be replaced immediately to avoid continued use that leads to a decrease in braking performance and causes safety accidents.
Adjust the parameters of the braking system: According to the inspection results, if the parameters of the braking system deviate, such as inappropriate tightness of the brake line and uneven braking force of the brake, timely adjustments are required to restore the braking system to the best working state.
Cleaning and lubrication: During the inspection, if dirt, dust and other impurities are found in the brake system, it should be cleaned in time and the relevant parts should be lubricated to reduce friction and wear and improve the service life and performance of the brake system.

8. Common misunderstandings in brake system inspection and maintenance

Ignoring regular inspections: Some users believe that the electric wheelchair brake system does not need to be frequently inspected when there is no obvious fault. This concept is wrong. Only through regular inspections can potential problems be discovered in time and prevented before they happen.

Over-reliance on professional maintenance personnel: Although professional maintenance personnel have professional knowledge and skills in brake system inspection and maintenance, users and caregivers should also master some basic inspection methods and common sense to find problems in daily use and communicate with professional maintenance personnel in time.

Use of inferior parts: When replacing brake system parts, inferior parts are used to reduce costs, which may lead to poor braking performance, frequent failures and other problems, but the gains do not outweigh the losses. Reliable and standard parts should be selected for replacement.

9. Summary
The inspection cycle of the electric wheelchair brake system should take into account the frequency of use, the use environment, the weight of the user and other factors. It generally includes daily quick inspections before each use and regular in-depth inspections every 3-6 months. At the same time, it is necessary to focus on the inspection focus and cycle of different brake components, use professional equipment for accurate inspections, and perform maintenance and care in a timely manner according to the inspection results to avoid common misunderstandings, ensure the reliable performance of the brake system, and protect the safety of users, so that electric wheelchairs can better serve people with limited mobility and provide them with a safe and convenient travel experience. It also helps to improve the quality reputation and competitiveness of electric wheelchairs in the international market and promote their sales and development in the international wholesale procurement market.
