Do you know the testing standards for electric wheelchairs?
With the advancement of time, the improvement of people's living standards and the rapid development of the medical industry, wheelchairs, as a more commonly used medical and means of transportation, are common equipment for the disabled and every family with the elderly. With the development of wheelchairs, there are two types of manual wheelchairs and electric wheelchairs, among which electric wheelchairs are more powerful. Recently, some netizens said that it is inconvenient for the elderly at home, and they want to buy an electric wheelchair for the elderly to facilitate their movement, but they do not know the various technologies of electric wheelchairs, and they do not know how to refer to the selection. A secure, easy-to-use wheelchair.
So what are the test standards for electric wheelchairs? The following is an introduction to the test standards for wheelchairs, which is convenient for your reference when choosing.
1. Wheel landing
When the user walks autonomously, accidentally presses on a stone, or crosses a small ridge, other wheels cannot be left in the air, causing the direction to lose control, and the sudden turning of the car poses a threat.
Test requirements: Raise any wheel of the manual four-wheeled wheelchair equipped with the experimental dummy by 20mm, and the other wheels should touch the ground.
2. Seat impact resistance
Generally, it is not easy for wheelchair users to get up and sit down slowly, and they often sit down abruptly, so the seat is required to have a certain strength.
Test requirements: place the wheelchair horizontally on the test bench, let the football with iron sand mass of 25 kg fall freely on the seat for 3 times from a height of 250 mm, and there should be no deformation, fracture, tear, desoldering and damage. and other abnormal phenomena.
3. Static stability
When the user drives autonomously and wants to climb up (down) a ramp, or drive laterally through a ramp, the wheelchair itself is very light and easy to tilt, but within a certain gradient, it cannot "turn over on its back" , "buckle down" or tip over sideways.
Test requirements: Put the manual four-wheel wheelchair with the test dummy and the brake on the test platform with adjustable slope, first place the electric wheelchair in the direction of pushing up and down the slope, and increase the platform at a constant rate The incline, within 10°, the wheels on the uphill position shall not leave the test table; then place the wheelchair at right angles to the slope to the left and right, within 15°, the wheels in the uphill position shall not leave the test table.
4. Slope performance
The wheelchair caregiver pushed the user to the slope and braked the brakes to leave. As a result, the wheelchair slipped down the slope or rolled over, which is unpredictable. This indicator is to avoid such situations from happening.
Test requirements: Adjust the brakes of the manual four-wheeled wheelchair equipped with the test dummy properly and brake it tightly, and place it on the test platform with adjustable inclination in four directions: forward, backward, left and right. In the drag position, the inclination of the platform is increased at a constant rate, and the phenomenon of rolling, sliding and the wheels leaving the test table shall not occur within 8°.
The above are some of our implementation standards for electric wheelchairs and the corresponding test methods. For consumers, buying a reliable, safe and qualified product is the wish of each of us, but for some profiteers and black-hearted businessmen, they are desperate to seek benefits.
