4 Common Questions and Suggestions for Power Wheelchair

Electric wheelchairs are an important means of transport for the elderly and disabled due to the rapid growth of the medical field. The current electric wheelchair industry is at its height, whether it's a power wheelchair. It is important to ensure the safety and effectiveness of this electric wheelchair, as it is used by elderly people or those with disabilities. What are some of the most frequently asked questions about the power wheelchair and what suggestions can you make? Next, let's have a look.

This is the list of content:

  • Stop driving when charging

  • Motor Stall Protection

  • Impact Strength

  • Double Roll Fatigue Strength

Don't charge while driving

The cord can break or fall off if the user accidentally drives during the charging. This can expose live parts. In recent years, the problem of driving not being inhibited while charging has been a common one in both registration inspection supervision and sample tests. Before leaving the factory, it is recommended that the controller program be set to disable driving while charging. If the power wheelchair has two charging connectors it is important to ensure that one of them does not operate the power wheelchair when the other is charging.

Motor Stall Protection

The power wheelchair may encounter obstacles and the drive motor can stall. The drive motor will begin to heat up because of the excessive current. Overheating can cause permanent damage or even put the life of the operator at risk. In the testing process, the most common problem is that the power wheelchair is not equipped with an over-current device. This will cause the motor and controller to overheat. The power wheelchair manufacturer should configure an overcurrent protection device to the external circuit on the controller or battery. This will automatically disconnect the circuit if an excessive current is detected.

Impact Strength

When driving a electric wheelchair, you will inevitably experience a variety of sudden impacts. The impact strength test measures the resistance of the parts of the electric wheelchair. The impact strength test is the impact of an object with a specific mass on an electric wheelchair vehicle. This includes the impact when the user is seated in the power wheelchair, the impact on the backrest, and the impact from obstacles on the hand rings, casters, and footrests. The most common issues after the impact strength tests are looseness, deformation, and damage to the footrest. The manufacturer should consider the impact resistance when choosing the casters or the footrest.

Double Roll Fatigue Strength

The two-roll test is a test that involves bumping the electric wheelchair 200,000 times in a two-roll testing machine, under the maximum load conditions specified by the supplier. In the inspection process, the most common unqualified phenomenon is deformation and fracture in the power wheelchair crossbar. The crossbar is the primary load-bearing component of the electric wheelchair. If the inner diameter and the wall thickness of this part are too small or too thin, the crossbar can easily break when subjected to multiple jumps in an environment of high strength. To address the unqualified phenomenon above, electric wheelchair manufacturers should focus on two key points. The first is to select a crossbar with as thick a pipe wall as possible to increase the strength of support.
