Many people think that wheelchairs are for people with disabilities. What kind of wheelchairs do the elderly need? In fact, this is a very unscientific concept.
”
Crutches, wheelchairs, electric wheelchairs and other devices are used to assist the elderly in walking. They can provide help as soon as possible when the elderly are not easy to move. They can exercise properly but not overwork, so as to extend or even restore the elderly's walking ability. At the same time, they can greatly reduce the probability of injury caused by accidental falls.
If the user completely loses the ability to walk, all the mobile aids will lose the significance of assistance and become pure walking substitutes.
Wheelchair / electric wheelchair is not the "patent" of a certain kind of people. To some extent, it is an investment in the health of the elderly and reducing the family medical expenditure.
Today, let's talk about how to choose a suitable electric wheelchair in the dazzling electric wheelchair market.
3 Motor
Motor is the power guarantee of electric wheelchair.
Electric wheelchair motor is divided into brush / brushless. The brush motor needs to replace the carbon brush regularly, so the driving inertia is small; Brushless motor does not need maintenance, but the speed is fast, there is a very slight inertia.
The quality of motor depends on the material of magnetic cylinder and coil, and there is a price difference. At the same time, when choosing the electric wheelchair, we need to compare and observe the factors such as the workmanship, power and noise of the motor.
The tightness of gearbox oil seal and seal ring is very important.
4 battery
In three words, lithium batteries are more expensive than lead-acid batteries, so many products on the market still use lead-acid batteries, which vary from person to person.
5 tires
The tires of electric wheelchair are divided into pneumatic tire and solid tire.
Solid tire is more wear-resistant and explosion-proof, the disadvantage is that the shock absorption effect is not good, and the bumpiness is obvious when the ground is high and low; Pneumatic tires have relatively good shock absorption effect. It's very comfortable to sit. Just pump air frequently.
6 brake system
The electromagnetic braking system can ensure the safety of the elderly when operating the electric wheelchair or electric scooter. If you let go, it will brake automatically. It will not slide and brake immediately, even on the uphill and downhill roads, which can ensure the safety of the elderly.
