For individuals with disabilities, using mobility aids such as electric wheelchairs is essential. So what distinguishes these electric wheelchairs from conventional manual wheelchairs? Let's explore more about this product below.
What is an electric wheelchair?
An electric wheelchair is a specialized vehicle designed to assist people with disabilities in mobility. It utilizes electric motors on the two rear wheels to facilitate easy movement across various terrains. While the design may not differ significantly from manual wheelchairs, it incorporates electric motors.
Features of electric wheelchairs
Electric wheelchairs are much larger in size compared to typical manual wheelchairs. The weight of standard wheelchairs ranges from 28-70 kg, depending on the manufacturer, and the design varies accordingly.
Most common types of electric wheelchairs
- Steel frame electric wheelchairs: These are heavier than typical aluminum frame wheelchairs and are more affordable. They are constructed from electrostatically painted steel or bent and welded steel.
- Aluminum frame electric wheelchairs: These are made from aluminum alloy frames, known for being extremely lightweight and resistant to corrosion over time. They are less prone to metal corrosion due to environmental factors.
Structure of electric wheelchairs
Mechanical structure
- Electric wheelchairs operate with the support of an electric motor drive system and a steering system. The drive system includes an energy converter, motor, energy control unit, and battery.
- Other key components of electric wheelchairs include: frame, wheels, steering motor, and speed controller. Additionally, the wheelchair is equipped with a joystick and signal lights.
- The motor operates unidirectionally based on magnetic fields with a maximum power of 120W. The steering motor has a power of 30W with belt drive.
- The battery has a voltage of 12V-9Ah.
How do electric wheelchairs operate?
Electric wheelchairs use electric current to power the motor and facilitate movement. The main operations of the wheelchair include turning left, turning right, and applying brakes.
For electric wheelchairs equipped with electric brakes, they typically have a strong power output of 320W or more and are more expensive. These types usually have a durability of up to 10 years compared to conventional wheelchairs.
For electric wheelchairs without electric brakes, they are designed quite simply with a gearbox combined with a brush motor. The cost of this type is relatively low, with a durability ranging from 3-5 years depending on the brand.
