The weight depends on the required use:
The original intention of the design of the electric wheelchair is to realize independent activities around the community, but with the popularization of family cars, there is also a need for frequent travel and carrying.
If you go out and carry it, you must consider the weight and size of the electric wheelchair. The main factors that determine the weight of a wheelchair are the frame material, battery, and motor.
Generally speaking, an electric wheelchair with an aluminum alloy frame of the same size and a lithium battery is about 7-15 kg lighter than an electric wheelchair with a carbon steel frame and a lead-acid battery. For example, Shanghai Mutual’s wheelchair with lithium battery and aluminum alloy frame weighs only 17 kg, which is 7 kg lighter than the same model of the same brand, which also has an aluminum alloy frame but uses lead-acid batteries.
Whether the motor is a lightweight motor or an ordinary motor, a brush motor or a brushless motor. Generally speaking, lightweight motors are 3 to 8 kg lighter than ordinary motors. Brushed motors are 3 to 5 kg lighter than brushless motors.
For example, compared with the Yuwell electric wheelchair on the left below, the Hubang electric wheelchair on the left has an aluminum alloy frame and lead-acid batteries, but Hubang uses a lightweight brushed battery, and Yuwell uses a vertical brushless motor. The Hubang on the left is 13 kg lighter than the Yuyue on the right.
Generally speaking, the lighter the weight, the more advanced technologies, materials and processes are adopted, and the portability is stronger.
Durability:
Big brands are more reliable than small ones. Big brands consider the long-term brand image, use sufficient materials, and have exquisite workmanship. The controllers and motors they choose are relatively good. Some small brands mainly rely on price competition because of their lack of brand influence, so materials and workmanship will inevitably be cut corners. La. For example, Yuwell is the leader in home medical equipment in our country, and Hubang is a participant in the formulation of the new national standard for wheelchairs in our country. Hubang wheelchairs were used in the ignition ceremony of the 2008 Paralympic Games. Nature is real.
In addition, aluminum alloy is light and strong. Compared with carbon steel, it is not easy to corrode and rust, and its natural durability is stronger.
In addition, lithium batteries have a longer life than lead-acid batteries. The charging times of lead-acid batteries are 500~1000 times, and the charging times of lithium batteries can reach 2000 times.
safety:
As a medical device, electric wheelchairs generally have guaranteed safety. All are equipped with brakes and seat belts. Some also have anti-rollback wheels. In addition, for wheelchairs with electromagnetic brakes, there is also an automatic brake function for slopes.
Comfort:
As a device for people with disabilities to ride for a long time, comfort is an important consideration. Including the height of the seat, the length and width of the seat, the distance between the legs, the driving stability, and the actual riding experience. It is best to go to the scene to experience it before purchasing. Otherwise, if you buy it and find that the ride is uncomfortable, even if the manufacturer agrees to return or exchange the product, an electric wheelchair weighs tens of kilograms, and the shipping fee of several hundred yuan will still have to be paid by yourself, because this is not a quality problem after all. You can go to the Jimeikang rehabilitation equipment experience centers in various places to experience it on the spot before deciding to buy it.
After-sales service:
Electric wheelchairs cost 2, 3,000 or even thousands of yuan each. They are considered high-end durable goods, and no one can take care that they will last a lifetime. Such an expensive device, what should I do if it breaks down? Therefore, it is recommended that you try to choose those big brands that have passed the test of time. The company has strength and after-sales guarantee. In our actual work, we often encounter some people who bought small-brand wheelchairs in other places, and after a while they couldn’t find after-sales manufacturers
