When choosing an electric wheelchair, in addition to the appearance and smart configuration, Dali believes that the most important thing to consider are the three main components: battery, motor and brake.
The battery determines its life and should be carefully selected based on the daily travel distance of seniors; The engine determines the power and should be selected based on the travel conditions of the elderly. If you need to climb hills and mountains, choose a high-power engine.
Lastly, there is the braking system. It is the most important part to protect the safety of seniors when traveling. It is necessary and responsible for older people and their families to understand this.
Currently there are two types of braking systems for electric wheelchairs: electromagnetic brakes and electronic brakes (EABS brakes) + hand brakes. So which of the two brakes is safer for seniors? Today Dalí will present it to you in detail.
1. The difference between electromagnetic brakes and electronic brakes (EABS brakes)
Different braking principles: Electromagnetic brakes depend on the interaction force between magnetic poles to achieve braking. Equipment such as electric vehicles, roller coasters, and high-speed trains use this type of electromagnetic brakes. Electronic brakes use friction to stop.
Prices and maintenance costs are different. The structure of electromagnetic brakes is a little more complicated, and the cost of materials is also relatively higher. Therefore, the sales price is more expensive and maintenance more problematic. Relatively speaking, the price and maintenance costs of electronic brakes are lower. In general, the price and maintenance costs of electronic brakes are lower. The price of electromagnetic brakes is about 200 yuan more expensive than that of electronic brakes.
Different electromagnetic safety brake systems can ensure the safety of elderly people when using electric wheelchairs.
The system is designed so that once the elderly person releases their hands from the operating lever, the brakes automatically take effect. Even when going up or down a hill or when the power of the electric wheelchair runs out, it can prevent the wheelchair from sliding, effectively ensuring the safety of the elderly. Equipped with electronic brakes, they may not work properly in scenarios such as going up and down hills, the electric wheelchair runs out of power, accidentally pressing the power supply or the circuit has poor contact, posing safety risks to people. old people.
Although some electric wheelchairs equipped with electronic brakes are also equipped with hand brakes on both sides, when elderly people encounter an unexpected situation and need to brake suddenly, their reaction speed is difficult for them to brake successfully and avoid the accident. danger.
2. Electromagnetic brakes and electronic brakes. How to choose an electric wheelchair? If older people travel on a flat road and do not need to go up and down hills, they can opt for electronic brakes. However, for the safety of the elderly, it is strongly recommended that everyone choose an electric wheelchair equipped with an electromagnetic brake.
3. How to judge whether an electric wheelchair is equipped with electromagnetic brakes?
The first method is to consult the seller directly. The second is to turn off the electric wheelchair he bought and push it forward. If it can be pushed slowly, it means that the electric wheelchair is equipped with an electronic brake. On the contrary, if it cannot be pushed, it is an electromagnetic brake.
