Technology has changed the world. With the advancement of technology, there are more and more types of means of transportation for the elderly to travel. Different people have different needs. While electric wheelchairs bring convenience to the elderly, how to choose a suitable electric wheelchair for them is also a problem that cannot be ignored.
First of all, we need to understand the needs of the elderly hope. The electric wheel chair for the elderly is very different from the traditional hand-push wheelchair. The electric wheel chair is similar to the structure of a car, with strong stability and 360° rotation in place. The power button on the controller can toggle back and forth between forward and backward. If the car needs to be charged, it can be used for 2 hours after charging for 4 hours. The emergence of electric power wheel chairs makes the elderly feel that the society is still focused on them. The sunset is infinitely good, but it is only near dusk. In your old age, riding your car to see. Electric power wheel chairs are not just a walking tool, they are also the yearning of the elderly for life.
1. Carry out the test on the ground. First switch the electric wheel chair to the power-off state, and push it on the flat ground to observe whether the electric wheel chair driving wheel rotates. If there is rotation, the braking performance is poor, otherwise the braking performance is good.
2. Slope performance test. Choose a 10-15 degree ramp to place the electric wheel chair on the slope, switch the electric wheel chair to the closed state, push the electric wheel chair downward and observe whether the driving wheel of the electric wheel chair rotates; if the driving wheel rotates, the braking performance is poor, otherwise braking performance is good.
3. Weight test. Place the electric wheel chair on the above-mentioned ramp, then switch the power supply of the electric wheel chair to the closed state, place a weight of about 100 kg or sit on the electric wheel chair, and check whether the electric wheel chair slides slowly down the slope. The braking performance of this electric wheel chair is poor. It is not recommended for the elderly or the disabled. There is a danger of slipping when going up and down the slope. If the driving wheel of the electric wheel chair does not rotate or slide under the load, it indicates the braking performance of the electric wheel chair is good, so the elderly or disabled can use it with confidence.
4. Exercise test. Adjust the speed of the electric wheel chair to the fastest speed on the flat road or the above-mentioned ramp, then release the electric wheel chair control lever to check whether the braking distance of the electric wheel chair is too long. If it can stop within 50cm, the braking performance is good, otherwise This electric wheel chair has poor braking performance and is not recommended for the elderly or disabled.
The above are the simple methods used to test the braking performance and safety performance of electric wheel chairs when purchasing electric wheel chairs every day. The braking performance and safety performance of an electric wheel chair for the elderly or disabled are the primary considerations.
